Oral irrigator

Abstract

The invention relates to an oral irrigator. The oral irrigator structurally comprises a spray nozzle, an irrigator body assembly and a wireless inductive charging base. The spray nozzle is connected with the irrigator body assembly, the irrigator body assembly is fixed to the wireless inductive charging base component, and an irrigator body can be charged. An inner upper part assembly is connected to an upper-portion cavity of a handle, an inner lower part assembly is connected to a lower-portion cavity of the handle, and the two cavities are separated by a partition plate. A water pump is arranged in the inner upper part assembly, a water inlet valve plate and a water outlet valve plate are arranged in the water pump, the valve plates are opened or closed by utilizing a piston and a connecting rod in the water pump, water in a pump cavity in the inner upper part assembly flows in a sealed cavity formed by the upper portion of the handle, the partition plate and the inner lower part assembly and does not flow into the inner lower part assembly, a PCBA and a motor on the inner lower part assembly are isolated from the water, damage caused by contact with water does not occur, normal usage of the PCBA and the motor in the oral irrigator is ensured, and the problem that PCBA and motor damage caused by water leakage of water pumps of other brands of oral irrigators and accordingly the service life is not long enough is solved.

Description

technical field [0001] The present invention relates to a cleaning appliance for tooth cleaning and tooth protection, in particular to an appliance that isolates water running pipes from water-sensitive electronic components and motors that need to be protected. The flosser is easy to pull out, the nozzle has a position, and the flosser is inductively charged. Background technique [0002] The electronic components that need to be protected on the existing ordinary dental flossers, the motor and the water running pipeline are in the same chamber, and there is no seal to separate them. Once the water pump leaks or seeps, it will immediately infiltrate into the electronic components, and the motor will be damaged and cannot be used. . Ordinary dental flossers are all contact charging. There are contact terminals on the body. The contact terminals are prone to rust and aging after contact with water, resulting in poor contact and unable to charge. There are two positions for ...
