Water pump structure of electric oral irrigator

Abstract

The invention discloses a water pump structure of an electric oral irrigator. The water pump structure comprises a pump shell, the pump shell comprises a front pump shell and a rear pump shell, an elastic partition plate for dividing the pump shell into a pump cavity and a containing cavity is fixedly arranged between the front pump shell and the rear pump shell, the pump cavity communicates witha water inlet pipe and a water outlet pipe, an outlet of the water inlet pipe is provided with a one-way water inlet valve, an inlet of the water outlet pipe is provided with a one-way water outlet valve, a transmission rod driven by a motor to do reciprocating motion is arranged in the containing cavity, the front end of the transmission rod is connected to the middle of the elastic partition plate, and the rear end of the transmission rod is supported in a shaft hole in a rear end cover of the rear pump shell in a sliding mode. According to the water pump structure of the electric oral irrigator, the structure is simple, the production cost is reduced, the problem of abrasion between a pump cavity and a piston troubling technical staff in the field for a long time is overcome, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a dental flosser, in particular to a water pump structure of an electric dental flosser. Background technique [0002] For a long time, people generally use toothbrushes to clean their teeth. However, the existing toothbrushes can only clean the dirt and residues on the surface of the teeth, and it is difficult to completely remove the residues in the gaps between the teeth. Over time, "calculus" will appear on the teeth , not only will emit peculiar smell, but also cause periodontitis. Therefore people have to go to the hospital to wash their teeth, not to mention the high cost, but also to endure the pain. [0003] Based on the above-mentioned shortcomings of the toothbrush, at present, more and more people have chosen to use the dental flosser for cleaning and health care of the teeth. The dental flosser is mainly composed of a water pump and a nozzle. It uses a water flow with a certain pressure to rinse the teeth. The wa...

Problems solved by technology

This improvement, in essence, only reduces the direct wear between the piston and the second chamber, but the wear still inevitably occurs during the reciprocating motion, and the structure is very complicated, the production cost is increased, and the processing difficulty is increased. Big
