Description

[0002] In recent years, people have paid more and more attention to dental health. With the improvement of the quality of life, water flossers are becoming more and more popular because they can clean the gaps between teeth and gingival sulci that are difficult to clean with a toothbrush.

[0003] However, existing water flossers generally use a motor to drive gears, which in turn drive an eccentric wheel to rotate through gear transmission. The eccentric wheel drives the connecting rod to form a reciprocating motion in the cavity. The pressure difference formed by the reciprocating motion sucks water from the water tank out of the nozzle to rinse the teeth. Due to the gear meshing and the eccentric wheel structure, noise and vibration are generated during the high-speed movement of the motor, which can easily cause internal components to loosen and seals to fail, causing electrical safety hazards.
