Three years ago, I pulled weeds and bought my first electric toothbrush. It's the first time to use it, and my buzzing teeth are sore. After brushing, the smoothness of the tongue licking the surface of the teeth is unforgettable. For ordinary toothbrushes, electric toothbrushes are no different from the impact of cars on carriages at the end of the eighteenth century. Before the automobile was fully recognized, people were suspicious and ignorant of this new thing, just like many consumers lack cognition and prejudice about electric toothbrushes now.

Before I received the Oclean One intelligent sonic electric toothbrush, I also used several electric toothbrushes of different brands, among which there are many international brands and domestic cutting-edge products, and I can be regarded as an old brush friend. At present, the principle differences and use feelings of different electric toothbrushes can only be regarded as subjective feelings. At present, the evaluation of toothbrushes by domestic and foreign media can be very thorough. As a media person, this is somewhat irresponsible for consumers. As a consumer, it is unlikely to know the specific difference between 100 yuan and 2000 yuan electric toothbrush products.

Considering the Oclean One smart toothbrush in my hand, I think this toothbrush is still good, but not many people know what is good about it and what is the difference from other products. "Don't accept running points?" To quote Reebs, this time, I want to make the key points of electric toothbrush clear objectively.

This will be a long article. If you want to be kind to your teeth, I suggest you read it carefully.

What am I talking about when I say electric toothbrush?

The purpose of brushing our teeth every day is actually to remove food residues between teeth and dental plaque attached to the surface of teeth and maintain oral health. Despite brushing their teeth every day, 97% of the population in China are still in poor oral health (if you are interested, please search the third national oral health epidemiological survey report yourself). Dental calculus, dental caries, gum problems, dentin hypersensitivity, halitosis, dental stains and dental plaque are the seven most common problems in China, and most of them are directly related to whether brushing teeth is clean or not.

The electric toothbrush drives the brush head to simulate manual brushing through the vibration of the motor. The brush head vibrates tens of thousands of times per minute, which is much higher than manual brushing for one or two hundred times. The cleaning efficiency is higher, and it is easier to remove dental plaque that causes various dental problems. Therefore, oral cleaning ability has become the first key index of electric toothbrush. Then, how to judge the cleaning performance of an electric toothbrush, at present, consumers do not have a very clear selection criteria. In other words, consumers don't have the standard to judge the quality of electric toothbrushes, but more often rely on the trust of brands and the judgment of prices.

In addition, in addition to the cleaning ability, the electric toothbrush is an electrical appliance for daily use, and the experience, charging and battery life are also factors to consider the advantages and disadvantages of the product. Therefore, according to my accumulated experience in using various electric toothbrushes in recent years, my research on toothbrushes and consumers' concern about electric toothbrushes, I think the most important thing of electric toothbrushes is their cleaning ability, which accounts for more than 60% by weight. The remaining 40% is the experience including cleaning mode and battery life.

Before the evaluation, first understand the basic information of Oclean One smart toothbrush.

Appearance: Oclean, in addition to beauty, is more temperament.

Because the whole white body is slim, it looks longer than other electric toothbrushes, and the actual length is similar to that of mainstream electric toothbrushes.

The body surface of the Oclean One smart toothbrush looks like pearl luster, which is much better than the white of other brands. It is the kind of bright white with a metallic luster hidden underneath, and some angles even resemble the matte effect of metal. If you look closely, there will be different levels of texture. This feeling is very similar to the color of Lexus "supersonic white". At this point, the delicacy of Oclean One is even more expressive than the high-end models of some imported electric toothbrush brands.

According to the official introduction of Oclean, after the research and use of a variety of electric toothbrushes, in order to prevent the body of the electric toothbrush from being affected by mildew and degumming after one or two years of use, Oclean One adopts a complicated five-spraying and five-drying process: on the basis of transparent MBS shell, the first layer of gray-black primer is sprayed and then dried; After that, spray a second layer of silver primer. After drying, the third layer is white paint, the fourth layer is pearl powder paint, and finally the surface is sprayed with a nano water-repellent coating. Because of the multi-layer primer with different colors such as silver, white and pearlescent, although the cost has increased greatly, it has also obtained a beautiful, exquisite and layered appearance that can guarantee long-term use. The surface of the fuselage adopts the industry's first nano-coating, and the toothpaste foam is clean after washing.

Brush head: the secret of super cleaning power

Brush head is the most basic and key factor to determine the cleaning ability of electric toothbrush. The brush head looks simple, but every factor affects the cleaning performance and user experience. Oclean, a person's brush head is ugly, but there are many secrets behind it. I will tell them one by one.

Galloping

According to national standards, the bristles of ordinary toothbrushes have three different specifications: hard, medium and soft. Due to frequent vibration in a short period of time, bristles with too high hardness are easy to damage gums or even enamel. Soft bristles are usually used, and the diameter of bristles is between 5 mil and 6 mil (0.12mm-0.18mm). Bristles are usually made of nylon filaments. The nylon yarn invented by DuPont has the characteristics of high elasticity and weak water absorption (no water absorption, not easy to breed bacteria), which can play the role of cleaning teeth and massaging gums.

In order to improve the cleaning ability of toothbrush as much as possible, the brush head of Oclean smart toothbrush adopts the best bristles in the world, including Tynex brilliance &: 2016 brilliance Pro diamond bristles, Pedex triangular diamond bristles and fading-promoting bristles.

Common bristles are mostly cylindrical, and the cleaning area is limited when brushing teeth. However, diamond-shaped or triangular bristles have larger cleaning area and better cleaning ability than circular bristles.

Because the diamond-shaped bristles and triangular diamond-shaped bristles are smaller than circular bristles, they can go deeper into the teeth and have stronger cleaning ability to the deposits between dental plaque and teeth.

▲ Research data from DuPont: Comparison of cleaning ability between diamond-shaped bristles and ordinary round bristles.

Dupont diamond bristles

The brush head of Oclean One smart toothbrush adopts special diamond bristles, which is the same as Philips' 9-series high-end electric toothbrush. Diamond bristles look brighter in appearance than ordinary cylindrical bristles. This is based on Tynex Brilliance &；; 20 16 Brilliance Pro series bristles have a unique rhombic cross section, which not only improves the aesthetics of the brush head, but more importantly, rhombic bristles have more cleaning edges than cylindrical bristles, and their cleaning ability is stronger than that of cylindrical bristles, and they are also softer and more comfortable to taste.

Germany Pedex triangular bristles

The green bristles in the middle of the head of Oclean One smart toothbrush adopt German Pedex top triangular diamond bristles, and the principle is the same as DuPont diamond bristles. Pedex triangular bristles have three long cleaning edges, and their cleaning ability is better than that of cylindrical bristles. At the same time, the bristles are thinner, which makes it easier to clean teeth deeply and less irritating to gums.

Germany Pedex faded bristles

Toothbrushes are in contact with the mouth and water every day. Thick bristles are easy to breed bacteria and not easy to clean. It is generally recommended to replace the toothbrush or brush head every 2-3 months. In ordinary high-grade toothbrushes and electric toothbrushes, users are reminded to change toothbrushes by changing the color of some bristles. This discolored bristle consists of two layers of bristles made of different materials-a light-colored inner core and a very thin dark outer layer. The outer bristles gradually wear out during use, exposing the inner optical comb core, indicating that the brush head needs to be replaced. Generally, the discoloration time is three months.

Hair transplant quantity

The higher the amount of bristles planted on the toothbrush, the more bristles it contains, and the more cleaning contact surfaces with teeth, the stronger the cleaning ability. The hair planting density of Olcean One smart toothbrush head is 20% higher than that of ordinary toothbrush. There are two factors that can greatly increase the amount of hair planted on the Oclean One toothbrush. One is that the planting hole is not a traditional circle, but a long polygon, which can implant more bristles; Secondly, diamond-shaped and triangular diamond-shaped bristles are used, which are smaller than circular bristles and can accommodate more in the same area.

Oclean has made great determination to improve the cleaning ability of toothbrushes. Dupont and Padax diamond bristles are much more expensive than ordinary bristles because of the particularity of molding technology. At present, DuPont diamond bristles are only used in Philips' high-end brush heads.

Brush a circle

I don't know if you feel that when you use disposable toothbrushes in ordinary hotels, you will feel uncomfortable when brushing your teeth, and even your gums will bleed, but using your own toothbrush will not be so uncomfortable. Why is this? This is an ordinary hotel toothbrush, and the bristles are not completely rounded. In order to prevent the bristles with certain hardness from stabbing or scratching the gums due to cutting in the production process, one end of the bristles of the toothbrush in direct contact with the teeth and gums in the production process should be round. China's national standards clearly stipulate that toothbrush bristles must be rounded, and the rounding rate must reach 50% to be qualified.

For the disposable toothbrushes provided by most hotels, from the perspective of cost saving, the rounding rate of bristles is usually poor, and it is easy to stab and scratch gums when brushing teeth.

From a 300-fold electronic magnifying glass, the top of the bristles of the Oclean One smart toothbrush is obviously round, which will not cause damage when touching the gums. Oclean official said that the grinding rate of smart toothbrush bristles is 1.4 times that of the national standard. From the practical experience, the polished toothbrush will not be swollen or painful after wear after use.

Diamond-shaped bristles with round tips.

Brush head modeling

The requirement of electric toothbrush for brush head is proper width and size, which generally covers 2-3 teeth, that is, it can clean 2-3 teeth at the same time. Most electric toothbrushes have smaller brush heads than ordinary toothbrushes, which can clean every corner of teeth more flexibly. Oclean One smart toothbrush has a slender brush head with a length and width of about 25mm* 1 1mm, which can cover about 2-3 teeth and is suitable for deep cleaning of molars or wisdom teeth.

Tongue coating brush

The middle and high-grade toothbrush head also has the function of cleaning the tongue coating, and the soft and hard materials are integrated on a brush head through a relatively complicated process. The back of the brush head of the Oclean One smart toothbrush has a circle line, which is very soft to the touch. This is a TPE material commonly used in baby pacifiers. As a tongue coating cleaning material, it can be integrated into the brush head, which can not only protect the soft tongue, but also clean the residue on the surface of the tongue coating and reduce the generation of breath.

In addition to cleaning the tongue coating, the tongue coating brush also has the advantage of cushioning and protecting teeth when the brush head contacts teeth, so as to prevent the high-speed vibrating brush head from "hitting" the teeth.

Counterweight iron ring

After using a lot of electric toothbrushes, the brush head of the electric toothbrush is not only different in shape from the bristles, but also the bottom of the brush handle. High-end models usually have a metal ring at the bottom of the brush head, which looks more beautiful and taller, but ordinary brush heads can't see this metal ring. The metal ring used in the high-end brush head is not only more beautiful, but also can play the role of counterweight and change the center of gravity of the brush head. When the motor vibrates at high speed, the lighter end tends to vibrate more. This principle can be explained by a tumbler. The tumbler is heavy at the bottom and light at the top. When pushing the tumbler, the top swings greatly and the bottom swings slightly.

The seemingly simple brush head is not easy to learn. In my opinion, in the brush head part, it is the type of bristles that determines the cleaning ability. The diamond-shaped and triangular diamond-shaped bristles of Oclean One have longer cleaning edges than the circular bristles, and their cleaning ability is more remarkable. Other parts, such as the amount of hair transplant, modeling, materials, etc. It can make the cleaning ability of bristles play a more extreme role.

Strong motor: whether the toothbrush is good or not depends on whether the motor is strong or not.

The brush head is responsible for cleaning, and the motor is responsible for driving the brush head to clean. Motor is the most important core of electric toothbrush. Just as the engine of a car determines the performance of the whole car, the performance of the motor also determines the cleaning ability of the electric toothbrush. As far as the electric toothbrush is concerned, the performance of the motor is determined by three key data: vibration frequency, swing amplitude and torque.

The motor of Oclean One smart toothbrush is a linear programmable brushless acoustic motor jointly developed by Oclean and Jinlong Electromechanical Co., Ltd., with the maximum effective vibration frequency of 42,000 times per minute and the torque of 280gf.cm This motor should be the most powerful of its kind. For Jinlong electromechanical, most readers may feel strange. In fact, Jinlong Electromechanical Co., Ltd. is the China brand with the largest shipment of micromotors in the world. For example, the miniature linear motors used in high-end smart phones such as Apple Samsung and smart watches are all produced by Jinlong Electromechanical.

Brushless structure with high vibration frequency.

Vibration frequency refers to the number of times the motor vibrates per unit time. Theoretically, the higher the effective vibration frequency, the higher the cleaning ability. Compared with manual brushing only 100-200 times per minute, the vibration frequency of the mainstream electric toothbrush now ranges from 15000 times per minute to 3 1000 times, which is several times faster than manual brushing. Come on, friends, do the math yourself.

The maximum vibration frequency of the motor of the Oclean One smart toothbrush can reach 42,000 times per minute, which is the most effective cleaning frequency in the acoustic toothbrush at present. This kind of motor adopts brushless electromagnetic levitation design, and the rotor is small in size, light in weight, small in inertia and fast in transient speed. In addition, it does not have the friction loss of the brush of the traditional brush motor or the travel limit of the fixed mechanical limit motor, and can realize a very high effective vibration frequency.

In order to test whether Oclean One can really reach 42,000 vibrations per minute, I tried many methods and found many devices on Taobao, but unfortunately I couldn't afford them. Later, Apple APP STORE found a software to test the frequency of musical instruments. That's an app called "Tuner" launched by Panorama Software Company, which uses the excellent pickup of Apple's mobile phone for frequency detection. Since Oclean One is also an acoustic toothbrush, its frequency can be tested with stable sound, and the number of vibrations of the toothbrush can be detected through conversion.

The frequency is displayed as 350Hz per second, 1Hz is vibration twice, and then multiplied by 60 seconds, the calculated vibration times are 42,000 times.

According to the senior engineer of Jinlong Electromechanical Company, it is actually easy for the motor to vibrate more than 40,000 times per minute, but it is very difficult to increase the amplitude at such a high frequency. Due to the limitation of technology and electromagnetic performance, the amplitude of most motors will be greatly reduced or even lost at high frequency. Therefore, in order to achieve effective amplitude, most electric toothbrushes on the market control the vibration times to about 30,000 times per minute, while some electric toothbrushes with weak performance can only get about 25,000 times per minute.

PS: The difference between brush motor and brushless motor;

The difference between a brush motor and a brushless motor is whether it is equipped with an ordinary brush. The rotor of the brush motor is wound with a coil, and the current contacts the annular electrode installed on the rotor through the brush to realize electromagnetic conversion and achieve the purpose of electrode rotation. Brushed motor technology is mature, but due to the friction of conductive brush, it is relatively weak in efficiency and life. Because the rotor is wound with thick copper wire, the inertia is relatively large when rotating, and the reciprocating rotation requires relatively large electromagnetic force, and the vibration frequency is not particularly high. It is generally used in daily electrical appliances that are not particularly demanding.

There is no coil on the rotor of brushless motor, so there is no need to conduct current through brushes. The volume and weight can be made relatively small, and a very high rotational speed can be obtained. The electromagnetic coil of the motor is on the stator, which can generate a magnetic field to drive the rotor to rotate after being directly energized. No noise and resistance caused by brush friction, less overall noise, higher power conversion efficiency, higher torque output, longer service life and no maintenance. For example, the motors of DJI UAV and Tesla motors are all brushless motors with high speed and large torque.

▲ Brush motor

High frequency and high torsion.

High vibration frequency, large torque and large swing are the motor characteristics of Oclean One smart toothbrush. In the torque part, the torque of the common electric toothbrush is between 150 gf. cm-230 gf. cm, while the torque of the Oclean One smart toothbrush motor is much higher than other motors, reaching 280 gf.cm..

The meaning of 280gf.cm is simply understood as that when the shaft of the motor extends vertically to the arm of 1 cm, an object weighing 280 g can be pushed. It is estimated that science and engineering men can also understand this sentence. For most people, it is only necessary to know that this figure is much higher than the torque of many electric toothbrushes from 150gf.cm to 230gf.cm.

The significance of torque to electric toothbrush is that when brushing teeth, if the torque is small, the motor can't effectively drive the brush head to swing, and the swing of the brush head is restrained, so that it can't form effective vibration, and the cleaning ability is greatly weakened. When the torque of the motor is large, even if the force applied to the brush head is large, the motor can still drive the brush head to vibrate, forming an effective vibration swing, and the cleaning ability can be guaranteed.

Ordinary toothbrushes generally exert 300-500g force on teeth when brushing teeth. When the electric toothbrush is in use, a force of 100-300g is usually applied to the brush head, so when the motor torque of the electric toothbrush is not enough, the brush head cannot vibrate effectively under a certain pressure, and the cleaning ability is not as good as that of the ordinary toothbrush. You get what you pay. I don't recommend electric toothbrushes that are too cheap or have too low motor torque.

The relationship between frequency and amplitude

Because there are many kinds of motors, there are also various data about the swing of motors. Physically speaking, the higher the swing frequency, the smaller the swing amplitude, and the larger the swing amplitude, the lower the frequency. There is a natural contradiction between the two. It is relatively easy to obtain a relatively large amplitude at lower frequencies, but it is very difficult to obtain a relatively large amplitude at higher frequencies.

The swing of electric toothbrush refers to the amplitude of reciprocating vibration of brush head driven by motor. The vibration amplitude of brush heads of different brands of electric toothbrushes is usually between 3 mm and 5 mm. This data seems insignificant, but it is full of articles. The crown height of normal adults (that is, the part of teeth exposed outside the gums) is between 7mm- 1 1mm, and the maximum crown of upper and lower jaws will not exceed 20 mm. Based on this data, the brush head width of electric toothbrush is generally around 10mm, and the vibration amplitude of vibrating bristles will not exceed the length of teeth when working. Due to the performance limitation of the motor, the amplitude of the brush head of many electric toothbrushes is often less than 5mm, and the cleaning ability is relatively insufficient.

Laser hanging weight test swing

Although the swing is similar to torque, it can also directly reflect the performance change of the motor with pressure load: when there is no pressure load, the swing is the largest. If the swing becomes smaller after adding a certain weight load, the intuitive torque performance of the motor can be calculated.

In order to test the motor performance of electric toothbrush, I specially made a scheme to test the torque of electric toothbrush. Under the condition of fixing the toothbrush, I simulated the stress on the toothbrush head, and hung weights with different weights on the toothbrush head. Hanging weight is equivalent to pressing hard on the brush head and vice versa. So as to test the torque of the electric toothbrush motor.

The brush head and the laser lamp are fixed together by clips. When the electric toothbrush swings after opening, the light projected by the laser lamp can be clearly presented, so that the length can be directly measured.

Different weights are hung on the fixed toothbrush to simulate the stress on the brush head and teeth, and the laser length projected on the scale will change with the hung weights.

Hanging weights with different weights in increments of 50gbit until the hanging weights reach 900g, the brush head stops swinging due to excessive force, and the projected laser changes from line to point.

During the test, record the length of the projected laser after increasing the hanging weight of 50g, and draw the following table and an intuitive torque diagram:

From the curve of the chart, we can intuitively reflect the difference between Oclean One smart toothbrush and other brands. When the load exceeds 600g, there is still a certain swing, while other similar products can not effectively vibrate when the load exceeds 300g, and the cleaning ability is obviously limited.

The reason why the Oclean One smart toothbrush motor is strong is that Jinlong Electromechanical has profound technical advantages for many years, and the other is that the materials are superior. For example, the magnet on the motor rotor is rare earth NdFeB with high magnetic energy product, which is three times the magnetic flux of ordinary magnets. Its volume is small, but its magnetic flux is very high, and it can absorb iron more than 600 times its own weight. The cleaning power of the electric toothbrush also depends on the performance of the motor. I hope everyone will pay attention to its motor performance parameters when buying. It's better to buy the right one.

Cleaning effect test

Almost all media will use dentures as a test of cleaning ability when evaluating electric toothbrushes. In my opinion, this does not objectively reflect the advantages and performance of electric toothbrushes, and needs to be different. This assessment, I am going to do something different: brush quail eggs.

There are many dark brown spots on the surface of quail egg shell. These spots are the pigment secreted by quail on the fallopian tube wall and deposited on the eggshell surface, and the pigment adheres to the eggshell to form unique spots. These spots are excellent camouflage and protective colors for quail eggs. It is very similar to black smoke stains and tea stains attached to teeth, and the spots on the surface of quail eggs are not easy to wash off. If you use an ordinary toothbrush, no matter how long it takes, it is difficult to brush off the spots on the surface. However, due to the high vibration frequency, the cleaning efficiency of electric toothbrush is 200-300 times that of ordinary toothbrush, and it is easy to brush off the spots on the surface of quail eggs during normal brushing time.

Many consumers still have a misunderstanding about electric toothbrushes, which is related to the health of teeth: electric toothbrushes are unsafe, and high-speed vibration will hurt teeth and even crack them. This question can be answered in the experiment of brushing quail eggs. The enamel on the tooth surface is the hardest tissue in the human body, which may break the hardness of quail egg shell with a light touch. When the electric toothbrush is used to remove spots, the eggshell is not broken, which proves the safety of the electric toothbrush.

APP soft power, intelligent black technology experience

Oclean One smart toothbrush is smart because it uses dialog's latest smart chip DA 1468 1, which is commonly used in various new smart wearable devices, such as Xiaomi Bracelet 2. Dialog DA 1468 1 has powerful integrated functions, such as multi-axis gyro angle sensor, self-contained memory chip, pressure sensing, Bluetooth 4.2 protocol, charge and discharge protection, etc. These functions are imperceptible to users. Let me first talk about the characteristics of Oclean One that I think is particularly good:

Intelligent frequency conversion splash prevention

With so many models of electric toothbrushes, there is an unavoidable problem. After the toothpaste is squeezed into the bristles, the brush head can only be sent to the mouth before brushing. If you open the brush head in advance, the toothbrush will be thrown everywhere, which is very disappointing.

This is a detail that many brands ignore by default. Oclean has made a very humanized intelligent solution: when the toothbrush has no pressure and resistance (contact with teeth), the brush head automatically vibrates at a very low amplitude and frequency. Once the brush head touches the teeth, the toothbrush will immediately increase the amplitude and frequency to the normal working state. If the teeth are taken out of the mouth when the toothbrush is working, the swing and frequency of the toothbrush will immediately drop to a very low level. Simply put, it does not touch the teeth, and the vibration is slow. Once it touches the teeth, it will work normally. In this way, the problem of toothpaste foam splashing everywhere is solved.

The splash-proof function of Oclean One smart toothbrush is to automatically adjust the vibration frequency and swing by sensing the pressure and resistance of the brush head, making the experience more humanized and intelligent.

APP multiple cleaning mode push

Brush your teeth and stare at your cell phone? This is not scientific. The concept of electric toothbrush introduced by some big brands does have this concept, and it is intuitive to tell whether the brushing posture is correct through mobile phones. I think this function is really an anti-human stunt. Using Oclean's APP, I feel that Oclean One has truly achieved the perfect combination of software and hardware. Most electric toothbrushes are more expensive and have more cleaning modes. As the proponent of the concept of smart toothbrush, Oclean App can directly push its built-in different brushing schemes (such as daily cleaning, super whitening, gum protection massage, maternal care, etc.). ) to the smart toothbrush, it also supports mobile phone customization, allowing users to choose different modes, gears, durations and free combinations. Theoretically, it supports unlimited brushing care scheme.

The first talking toothbrush

Oclean One smart toothbrush has built-in voice reminder function. In addition to different modes of voice reminders, you can also record voice reminders through Oclean App and set the reminder time. When brushing your teeth, the toothbrush will automatically play voice memos on time, such as reminding you of what you have to finish today. It's fun.

Oclean's intelligence is reflected in the powerful APP function. In addition to the above-mentioned mode push and voice reminder, APP software has many interesting functions, such as daily brushing data analysis and guidance, mode memory function, brush head replacement reminder, and recommendation from nearby dental clinics. If you are interested, you can go to the software market to download and experience it first.

Other details worth talking about.

Charge for several hours and use for 60 days.

My used electric toothbrush needs to be recharged almost every two or three weeks, every night or even all day. Sometimes I will encounter the embarrassment of brushing my teeth the next day, forgetting to charge it and turning it off. In order to achieve the waterproof purpose, the ordinary electric toothbrush adopts non-contact charging method, and the body is fixed on a special charging base for wireless charging. Usually, the charging efficiency of this method is relatively low, and it takes 12 to 20 hours for the electric toothbrush to be fully charged.

The way of wireless charging is simple and convenient in form, but it still feels a little inconvenient in actual use because of the long charging time. Oclean One smart toothbrush adopts a more direct contact charging method. On the basis of waterproof, the charging base is in direct contact with the gold-plated electrode ring at the bottom of the toothbrush, so the charging current is large and the battery can be fully charged in a short time. In addition, the charging base of Oclean One also has an automatic suction function, which can be automatically sucked together as long as the bottom of the toothbrush is close to the base.

Of course, the charging time depends not only on the charging method, but also on the built-in battery capacity. In order to control factors such as volume and cost, the battery capacity of many electric toothbrushes is around 1000 mAh, which is small in size and naturally much shorter in use time.

Oclean One smart toothbrush can be used continuously for 60 days after being fully charged. It is the longest toothbrush I know, and there is no one. There are two important reasons for this long time. One is the rationality of intelligent circuit design, and the other is the large battery capacity. Oclean One smart toothbrush adopts the same model 18650 lithium battery provided by LG as Tesla, with a capacity of up to 2600mAh. As the top supplier of lithium batteries, LG's 18650 lithium-ion battery has the advantages of large discharge current, small internal resistance and small leakage current, occupying the top position of lithium batteries.

IPX7 deep waterproof

Toothbrushes naturally contact water, and the waterproof performance of electric toothbrushes has also become a hard indicator of product quality. Oclean One smart toothbrush adopts IPX7 grade, which belongs to the standard with very high waterproof performance in electric toothbrush. IPX is an international industrial waterproof grade standard. Electric toothbrushes are usually waterproof between IPX5 and IPX7. IPX7 means that the product is immersed in water within 1 m, and it will not leak for 30 minutes, and its performance will not be affected.

Facts have proved that throwing the whole toothbrush into the water can still continue to work.

At the same time, even if the charging base is directly put into the water, it can still continue to charge.

Postscript of evaluation: smart toothbrush, as it should be.

The reason why Oclean One is called smart toothbrush lies in its core chip and APP software, which solves the potential demand from the user's point of view. Powerful hardware configuration only solves the most basic cleaning problem and can make the user's mouth healthier. In addition to the humanized intelligence of hardware and software, users can also know their oral health, and the unchangeable thing of brushing teeth becomes more fun. In addition, both Oclean APP and One toothbrush support OTA online upgrade, which can constantly update the firmware version like a mobile phone to achieve more functions. I think that since it is a smart toothbrush, it should be like this.

After the overall use evaluation, Oclean One intelligent sonic electric toothbrush has refreshed my standard cognition of electric toothbrush. Electric toothbrushes have a huge development space in China market, and various brands have sprung up like mushrooms after rain. Emerging products do not have very clear judgment criteria, and some products even exaggerate product functions and information, so that consumers have no clear judgment when choosing. I hope my article can bring you a new understanding of electric toothbrush. There are too many words, and the friends who can finish reading are probably true love teeth. This evaluation is more of an interpretation of the hardware of the Oclean One smart toothbrush. If you can read it patiently, I believe you will have a deeper understanding of electric toothbrushes, and at least you can tell the difference between high, medium and low-grade electric toothbrushes.
