AI Technical Summary

Technical Problem

The pump body in existing oral care equipment is prone to moisture leakage during use, which can lead to corrosion and damage to electronic components, and conventional sealing measures cannot effectively prevent the leakage of moist fluids.

Method used

By forming a sealed transmission chamber and drive chamber in the fluid pumping assembly, the housing component confines the humid fluid within the transmission chamber and isolates and seals the transmission chamber from the outside, preventing the humid fluid from spreading further to other areas. The housing component is not easily damaged and does not need to move with the transmission unit, ensuring the reliability and lifespan of the seal.

Benefits of technology

It effectively prevents moisture leakage, reduces damage to internal electronic components of oral care equipment, and extends the service life of the equipment.

Abstract

Provided are a fluid pumping assembly (1000) for oral cleaning and an oral care device. The fluid pumping assembly (1000) comprises at least a housing component (100), an execution unit (200), a transmission unit (300), and a driving unit (400). The housing component (100) is provided with an execution cavity (110), a transmission cavity (120), a driving cavity (130), and a liquid inlet (111) and a liquid outlet (112) that are in communication with the execution cavity (110); the transmission cavity (120) is isolated and sealed from the exterior of the housing component (100), and the transmission cavity (120) is isolated and sealed from the driving cavity (130); the execution unit (200) is disposed in the execution cavity (110); the transmission unit (300) is disposed in the transmission cavity (120), and the transmission unit (300) partially extends into the execution cavity (110) and is connected to the execution unit (200); the driving unit (400) is disposed in the driving cavity (130), an output terminal of the driving unit (400) extends into the transmission cavity (120) and is connected to the transmission unit (300), and the driving unit (400) drives the execution unit (200) to move in the execution cavity (110) by means of the transmission unit (300). The fluid pumping assembly (1000) can reduce the possibility of fluid leakage, thereby avoiding damage to electronic components inside the oral care device and prolonging the service life of the oral care device.
