Embodiment approach

[0094] Further, as an embodiment of the present invention, the sealing member 13 includes a piston.

[0095] It can be understood that the piston and the casing 11 jointly define the water passage, the piston can be just locked on the inner wall of the casing 11 to close the water passage, and one end of the central shaft 121 is fixedly connected to the middle of the piston, and the central shaft 121 is driven by the motor 12. The reciprocating motion is performed in the casing 11 to drive the piston to move in the water-passing chamber to change the pressure of the water-passing chamber.

[0096] Specifically, when the water pump 1 is running, the motor 12 drives the central shaft 121 to reciprocate axially inside the housing 11, thereby driving the piston to reciprocate in the water passage, thereby changing the pressure of the water passage. When the motor 12 drives the central shaft 121 to move axially in the casing 11 in the direction close to the piston, the piston will ...

Abstract

The invention relates to the technical field of liquid variable capacity, in particular to a water pump, a tooth cleaning device, a pump body device and a water pumping method. Comprising a shell, a motor and a sealing piece, the sealing piece is contained in the shell, the sealing piece and the shell jointly define a water passing cavity, the motor comprises a center shaft, an axial through flow channel is formed in the center shaft, and one end of the center shaft extends into the water passing cavity and is connected with the sealing piece; a water inlet hole communicated with the water passing cavity and the flow channel is formed in the side wall of the end, close to the sealing piece, of the center shaft, a water inlet channel communicated with the water passing cavity is formed in the shell, and the motor drives the center shaft to reciprocate in the shell, drives at least part of the sealing piece to move relative to the water passing cavity and changes the pressure intensity of the water passing cavity. The pressure change of the water passing cavity drives external fluid to enter the water passing cavity from the water inlet channel and then enter the flow channel through the water inlet hole to be discharged. The water pump is smaller in overall size and lower in noise. The tooth cleaning device, the pump body device and the water pumping method have the same effect as the water pump.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid variable volume, in particular to a water pump, a tooth cleaning device, a pump body device and a water pumping method. 【Background technique】 [0002] With the improvement of people's daily level, more and more products need to use small water pumps. The existing small-sized water pump is driven by gears, which leads to high noise and complicated structure of the pump body. [Content of the invention] [0003] In order to solve the problems of high noise and complex structure of small and medium-sized water pumps in the prior art, the present invention provides a water pump, a tooth cleaning device, a pump body device and a water pumping method. [0004] In order to solve the above technical problem, the present invention provides a water pump, the water pump includes a casing, a motor and a seal, the seal is accommodated in the casing and defines a water passage together with the casing, The...
