1) Is there a temperature adjustment function?

I usually prefer scented tea and health tea, many of which can't be boiled directly! With the temperature regulation function, making coffee, scented tea, milk powder and even health tea is not a problem. Dad and nanny get up in the middle of the night to make milk powder, so they don't have to doze off until the water boils before letting it cool. It can be said that it has solved a big pain point.

2) Direct drinking or storage?

This function is also very important. Direct drinking has three main advantages:

(1) The water comes out quickly, so don't wait.

② There is no need to store water, and it is not easy to produce scale and bacteria, polluting water sources.

(3) As long as the water supply is connected, there is no need to change water.

3) What kind of filtering method is used?

① Reverse osmosis technology

For example, the filter element used in Qinyuan KRL39 13 is RO membrane, which can remove all impurities in water, and the purified water is pure water without any impurities. A certain amount of wastewater will be produced in the process of filtration. However, reverse osmosis technology not only removes harmful substances, but also removes mineral elements beneficial to human body in water, which is not suitable for the elderly and children with poor resistance to drink for a long time.

② nanofiltration technology

For example, JD 1759S-NF of Midea adopts this method, which is a membrane separation technology between reverse osmosis and ultrafiltration. Like reverse osmosis technology, it will produce corresponding wastewater. Unlike reverse osmosis, it can retain most mineral elements and is suitable for the elderly and children to drink.

③ Ultrafiltration technology

For example, daogrs v3 uses ultrafiltration, which is a physical screening process that uses ultrafiltration membranes with different pore sizes to separate liquids with pressure as the driving force. It can remove most harmful substances such as heavy metals, bacteria and residual chlorine. And the trace elements needed by the human body are retained, and waste water is not generated, so that water is saved and the environment is protected. It is a widely used purification technology in the water purification market.

④ Microfiltration technology

For example, Qinyuan QJ-UF-502A(S), microfiltration is based on porous membrane, which can only remove some large particles of harmful substances such as sediment and rust in water, but still cannot remove smaller substances, so it is not recommended to drink the water directly after microfiltration.

Summary:

Drinking fountains can no longer meet the current drinking water demand, and healthier and more convenient equipment is needed to replace drinking fountains.

1) Under-kitchen water purifier (representative product: Qinyuan KRL39 13): It can only be used in the kitchen, and it can filter water but not heat it. Suitable for families without hot water demand.

2) On-stage drinking machine (representative product: Xiaomi-Mi Yun instant drinking machine): It occupies little space and is easy to use. However, it is necessary to change water frequently, clean the sink, and the filtration system is not in place or strong enough. Suitable for families with limited budget, limited space and small number of people.

3) Vertical water purifier (representative product: Midea JD 1759S-NF): The filtration system can meet the daily drinking water demand, but it takes up a lot of space, and the water pipes and power supplies will be messy. And clean the sink regularly. Suitable for families or companies with large space and a little more people.

4) Embedded pure water dispenser (representative product: daogrs v3): It can be embedded with other electrical appliances, saving space and being neat. With temperature regulation function, the direct drinking water is faster and more sanitary, and the filtering system is also reassuring. However, the location and water pipes need to be reserved in advance. Suitable for families or companies with reserved places and high requirements for drinking water.
