Water pump structure of portable oral irrigator

Abstract

The invention relates to a water pump structure of a portable oral irrigator. The portable oral irrigator comprises an oral irrigator host, wherein the oral irrigator host comprises a housing and a water pump assembly; the water pump assembly is arranged in the housing and is provided with a pump body, a drive motor, a water outlet nozzle and a water inlet nozzle; the housing is provided with a water inlet and a water outlet corresponding to the water outlet nozzle and the water inlet nozzle separately; the drive motor is vertically arranged; an output shaft of the drive motor is in transmission connection with the pump body through a straight gear and an end surface gear; the end surface gear is vertically and rotationally arranged in the housing; the pump body comprises a pump cylinder, a piston rod and a pumping piston head; the pump cylinder is a three-way pipe; the pumping piston head is arranged in one end of the pump cylinder and the other two ends of the pump cylinder are communicated with the water outlet nozzle and the water inlet nozzle respectively; and one end of the piston rod is connected with the pumping piston head and the other end is in eccentric running fit with the end surface gear. The pumping piston head is controlled through an eccentric driving mechanism to continuously move in the pump cylinder in a reciprocating manner, so that continuous pumping is achieved to reach the target of reliably working.

Description

technical field [0001] The invention relates to a portable dental flosser, in particular to a water pump structure of the portable dental flosser. Background technique [0002] Present portable flossers generally include a main body of the flosser, the main body of the flosser includes a housing and a water pump assembly, the water pump is arranged in the housing, and the housing is provided with a water inlet and a water outlet corresponding to the water pump. Because the water pump in the main body of the current dental flosser is an outsourced part, the molding of the portable dental flosser is designed according to the water pumps on the market. Therefore, the design of the portable dental flosser is greatly limited. In addition, because the quality of the purchased water pump is difficult to control and the volume is large, the portable dental flosser is unreliable and bulky. Contents of the invention [0003] The purpose of the present invention is to overcome the s...

AI Technical Summary

Problems solved by technology

Since the water pump in the main body of the current dental flosser is a purchased part, the shape of the portable dental flosser is designed according to the water pump currently on the market. Therefore, it brings great limitations to the design of the portable dental flosser

In addition, because the quality of the purchased water pump is difficult to control and the volume is relatively large, the portable dental flosser is unreliable and large in size
