Water pump for water toothpick

Abstract

The invention relates to a water pump for a water toothpick. The water pump includes a shell, a connecting cavity and a flow control mechanism, wherein the connecting cavity and the flow control mechanism are arranged in the shell, the flow control mechanism comprises a driving motor, a driving gear arranged on a rotating shaft part of the driving motor, an eccentric seat meshing with the drivinggear and a piston assembly. The eccentric seat is capable of being connected to the shell in a rotary mode and comprises a connecting shaft. The central axis of the connecting shaft is arranged relative to the rotary axis of the eccentric mounting in a deviating mode, part of the piston assembly extends into the connecting cavity, the connecting shaft is arranged on the piston assembly in a penetrating and rotary mode, the driving gear is arranged as an involute helical gear and drives the eccentric seat to rotate by meshing with the eccentric seat, and the piston assembly is driven by the rotation of the eccentric seat to perform piston motion in the connecting cavity. According to reasonable structural design of the water pump, the effect generated by the water column impact when the water pump works is improved, and meanwhile, the effects that noise is reduced, energy consumption is lowered and flow is improved are achieved.

Description

technical field [0001] The invention belongs to the technical field related to oral equipment, and in particular relates to a water pump for a tooth washer. Background technique [0002] The dental flosser is a conventional oral cleaning device, which uses the impact force of the high-speed water column ejected under a certain pressure to achieve the effect of cleaning the teeth. [0003] At present, the existing application and the water pump on the dental flosser usually adopt a membrane water pump, and the water is pushed out by the suction and thrust generated when the diaphragm inside is pushed and pulled back and forth. Because the suction and push action of the film requires high-speed and high-frequency action to inhale enough water, the vibration force and noise of the corresponding dental cleaner are relatively large, and the suction and thrust of water generated are small, making the corresponding The impact force of the water column generated by the professional...
