Description

Technical Field

[0001] The utility model relates to the technical field of water flossers, and in particular to a water flosser with a low-friction and easy-to-assemble water flosser pump connection structure. Background Art

[0002] As we all know, a water flosser is a small device used for oral hygiene care, usually consisting of a handheld nozzle and a water pump. It removes food debris, bacteria and other dirt from the mouth by spraying high-pressure water onto the teeth and gums, helping to prevent oral problems such as gingivitis and bad breath. The water flosser is easy to use and can adjust the intensity and spray angle of the water flow according to personal needs. It is suitable for various oral cleaning needs and can achieve deep cleaning of the tooth surface and gum gaps, thereby improving the level of oral hygiene.

[0003] However, in traditional water flossers, when the piston connecting rod is constantly moving in the piston cylinder, it may not be able to completely form negative pressure to drain the liquid into the stamping nozzle tube due to poor sealing, which may lead to unstable stamping effect and affect the quality and consistency of the product. Therefore, technical improvement is urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a water flosser with a low friction and easy-to-assemble water flosser pump connection structure. When the water flosser is in use, the bevel gear is driven to rotate by starting the servo motor, and the bevel gear is engaged with the cam gear plate, thereby driving the connecting rod and the piston connecting rod to move in the piston cylinder. At this time, the steel sleeve is driven by the movement of the piston connecting rod to form a reciprocating component, which then reciprocates against the piston cylinder. The gap between the piston cylinder and the piston connecting rod can be effectively sealed by the sealing ring to prevent gas or liquid leakage. This can ensure that a sufficiently closed environment is formed when the piston moves, thereby ensuring the stability and reliability of the stamping effect.
