Noise-reducing leak-proof durable pulse oral irrigator pump member

Abstract

The invention discloses a noise-reducing leak-proof durable pulse oral irrigator pump member. The noise-reducing leak-proof durable pulse oral irrigator pump member comprises a shell and a piston which is made from a composite nylon material, wherein a motor groove is formed in one end in the shell; a driving groove is formed in the center in the shell; a pump groove is formed in the other end inthe shell; a pump body is arranged in the pump groove; a piston is arranged in the pump body; the center of the driving groove is rotationally connected with a driven spiral bevel gear; and the top end of the driven spiral bevel gear is fixedly connected with an eccentric rotating column. After the piston makes contact with water, the whole piston can swell to ensure that the friction of the pumpbody and the piston neutralizes each other in the drawing process, so that the loss is reduced, and the sealing closeness of the whole drawing device and the pump body is improved. Much more drawing,much higher the closeness is, and the higher the pressure formed after water impact is; the higher the pressure is, the larger the water column is; and furthermore, the water in the cavity can be prevented from overflowing.

Description

technical field [0001] The invention relates to the field of dental flossers, in particular to a noise-reducing, leak-proof and durable pulse dental flosser pump body component. Background technique [0002] The dental flosser is an auxiliary tool for cleaning the oral cavity. It uses the impact of pulsed water to clean the teeth and the gap between the teeth. It is mainly portable and desktop. The general flushing pressure is 0 to 90 psi. [0003] During the use of the existing dental flossers, when the motor drives the pump body through gear transmission, the existing straight bevel gears or horizontally arranged involute gears are usually used for transmission, which will cause large noise, the existing one-way water inlet of the pump body is controlled by the one-way water inlet sheet, and the sheet is easily damaged during use, and needs to be replaced frequently, which is very troublesome. Contents of the invention [0004] The object of the present invention is to ...
