Description

Beauty instrument Technical Field The application relates to the technical field of beauty equipment, in particular to a beauty instrument. Background With the continuous improvement of the living standard of people, the demand for skin care is growing increasingly, and the rapid development of the beauty instrument market is promoted. At present, various types of beauty instruments are appeared on the market, and among them, beauty instruments using water light skin care as a main function are receiving a great deal of attention. Such cosmetic instruments are generally composed of three parts, namely a housing, a driving device and a water photoelastic. The water photoelastic is filled with skin care components such as essence or nutrient solution, and the piston is pushed to move by the driving device, so that the liquid is extruded out of the liquid outlet and acts on the skin, and the skin care effect is achieved. However, a significant problem with this type of prior art cosmetic device is that when the cosmetic device is used and turned off, the driving device automatically resets to separate from the piston, and the piston loses the holding effect of the driving device, so that air may enter the water photoelastic through the liquid outlet during the turn-off, and when the cosmetic device is turned on again, the driving device pushes the piston to move so that the liquid outlet is discharged, and the liquid outlet may discharge the gas-liquid mixture, resulting in uneven liquid discharge. The uneven liquid outlet phenomenon makes it difficult for the beauty instrument to accurately control the liquid outlet amount of the water photoelastic by controlling the movement of the piston, thereby affecting the skin care effect and the user experience.
