Oral irrigator

Abstract

The invention provides an oral irrigator. The oral irrigator comprises a shell body, a water inlet assembly, a water outlet assembly and a pump body assembly, the pump body assembly comprises a valve pump body, a piston and a driving device, the valve pump body comprises a water inlet valve base, a water outlet valve base and a pump body, and a water outlet is formed in the water outlet valve base; a water outlet valve block is arranged on the outer side of the water outlet, the water outlet assembly comprises a water outlet pipe and a water outlet pipe joint, the outer end of the water outlet pipe joint is connected with the water outlet pipe, and the inner end of the water outlet pipe joint is connected with the water outlet valve base; a water outlet valve cavity is formed in the water outlet valve base, the water outlet is formed in the middle of the bottom surface of the water outlet valve cavity, a water outlet valve block supporting rib is arranged around the water outlet and located on the bottom surface of the water outlet valve cavity, and several water outlet valve block guiding ribs are arranged on the periphery of the water outlet valve block supporting rib; the driving device drives the piston to reciprocate in the pump body, and the water outlet valve block reciprocates between the water outlet pipe joint and the water outlet valve block guiding ribs to control opening and closing of the water outlet. According to the oral irrigator, the viscous resistance of water flow to the water outlet valve block is reduced, and the stability of water flow sprayed by the pump body is improved.

Description

technical field [0001] The invention relates to the technical field of dental flossers, in particular to a dental flosser. Background technique [0002] The dental flosser is an auxiliary tool for cleaning the mouth, which uses the impact of pulsed water to clean the teeth and the spaces between the teeth. Generally, the high-speed rotating force of the motor drives the eccentric device to push the piston to reciprocate up and down to realize the opening and closing action of the water outlet valve and the water outlet valve, so that the pump body sucks and ejects high-pressure water flow to clean the teeth and teeth. Effect. [0003] At present, the water outlet valve seat of dental flossers on the market has a simple planar structure and a film sealing gasket of soft material in the structure. Large, easy to damage the sealing sheet, and the viscosity of the sealing gasket increases when it meets water, and the resistance increases, which reduces the spray water pressure...

Problems solved by technology

[0003] At present, the water outlet valve seat of dental flossers on the market has a simple planar structure and a film sealing gasket of soft material in the structure. Large, easy to damage the sealing piece, and the viscosity of the sealing gasket increases when it meets water, and the resistance increases, which reduces the spray water pressure and affects the practical effect of the product
