Abstract
The utility model discloses a diaphragm pump toothpaste squeezing mechanism. The rear end of a toothbrush head and the front end of a toothpaste tube are connected, the rear end of the toothpaste tube is connected with the front end of a diaphragm pump, a channel communicating toothbrush bristles and the toothpaste tube is arranged in the toothbrush head, a sealed air bin is formed by the diaphragm pump and a piston in the toothpaste tube, a pull wire is arranged between the piston and a pump diaphragm seat, the diaphragm pump seat is provided with a one-way exhaust valve communicating the air bin and the atmosphere and a one-way air inlet valve communicating the air bin and a diaphragm pump chamber, and a soft hemispherical pump diaphragm is arranged at the rear end of the diaphragm pump seat. By pressing the diaphragm pump for several times, the inside of the air bin is pressurized, the piston is driven by the pressure to squeeze toothpaste in the toothpaste tube slowly and continuously. When teeth are brushed, the toothpaste is not squeezed onto the toothbrush bristles in one time, but is continuously supplied according to the required amount for brushing the teeth, so that the phenomenon about loss and waste of redundant toothpaste caused by squeezing the toothpaste onto the toothbrush bristles in one time is avoided.
Description
Technical field
[0001] the utility model relates to a kind of toothbrush, belongs to daily necessities field, the membrane pump toothpaste extrusion mechanism that especially can continuously supply with according to the toothpaste requirement in the process of brushing teeth.
Background technology
[0002] toothbrush is a kind of people indispensable sanitary wares of living, and existing technology is when brushing teeth on the disposable bristle that is extruded into toothpaste toothbrush, but have more than is needed again so much toothpaste when brushing teeth at the beginning can make the loss of a part of toothpaste, causes waste.
Summary of the invention
In order to overcomeThe defective of prior art, the utility model provide a kind of membrane pump toothpaste extrusion mechanism that can continuously supply with according to the toothpaste requirement in the process of brushing teeth.
The technical scheme that the utility model adopted: the front end of brush rear end and toothpaste tube joins; The front end of toothpaste tube rear end and membrane pump joins; Be provided with the passage of UNICOM's bristle and toothpaste tube in the brush; It is characterized in that: the piston in membrane pump and the toothpaste tube forms an airtight gas storehouse, and pump seat is provided with the one-way exhaust valve of UNICOM gas storehouse and atmosphere and the breather cheek valve of UNICOM gas storehouse and pump chamber, and the rear end of pump seat is provided with a soft hemispherical pumping diaphragm.When brushing teeth, to press several membrane pumps down and just can brush teeth, membrane pump makes pressurization in the gas storehouse; The pressure-driven piston makes the toothpaste in the toothpaste tube pass through the toothpaste passage in the brush, gently, continuously is transported on the bristle; After having brushed tooth; Click the air bleeding valve button, the pressed gas in the toothpaste tube is discharged, in order to avoid toothpaste flows out.When filling toothpaste, screw off brush, the internal orifice that the toothpaste mouth precession is fixed on the toothpaste tube front end is trumpet-shaped soft toothpaste mouth interface, screws off membrane pump, is provided with draught line between piston and the pump seat, pulling outward piston just can be with toothpaste inspiration toothpaste tube.
The beneficial effect of the utility model is; Toothpaste is not disposable being extruded on the bristle in the process of brushing teeth; But in the process of brushing teeth, continuously supply with according to the toothpaste requirement of brushing teeth, be extruded into toothpaste on the bristle thereby avoided disposable, cause the phenomenon that unnecessary toothpaste runs off to be wasted.Screwing off that membrane pump pulls outward piston just can be with toothpaste inspiration toothpaste tube, and filling toothpaste is easy.
