A cup with a spring is called a "shake cup". Shake cups are suitable for bodybuilders, office workers and students, because they like to drink milk tea, soy milk powder and so on. However, these powders need to be constantly stirred and shaken during brewing, and it is difficult to fully mix with water or other dissolved substances. The spring in the cup can help the solid beverage to melt and prevent caking.

There is generally no fixed time to charge the electric shaking cup. There is a signal light on the shaker. When the color of the signal light changes, the charging ends. At present, there are two kinds of shaking cups on the market, electric and manual, which are convenient and flexible. The electric shaking cup is faster, which can better realize the interaction between objects and water quality.
