Abstract
The utility model relates to a plunger pump paste suction and extrusion mechanism. The front end of a plunger pump is connected with the back end of a toothpaste tube and forms a closed gas bin with a piston in the toothpaste tube, a gas inlet valve group and an exhaust valve group are arranged on a pump seat, and a cylinder and a plunger are arranged at the back end of the pump seat. The gas bin can be pressurized by pressing the plunger pump for a plurality of times, pressure can drive the piston to slowly and continuously extrude toothpaste in the toothpaste tube out, and the toothpaste is not extruded onto bristles once during the tooth brushing process, but is continuously supplied according to the demand quantity of the toothpaste for tooth brushing during the tooth brushing process, so that the phenomena of outflow and waste of the surplus toothpaste because the toothpaste is extruded onto the bristles once can be avoided. When the toothpaste is filled, the toothpaste can be sucked into the toothpaste tube by pressing the plunger pump.
Description
Technical field
The utility model relates to a kind of toothbrush, belongs to daily necessities field, especially can inhale the cream extrusion mechanism according to the plunger displacement pump that the toothpaste requirement in the process of brushing teeth is continuously supplied with.
Background technology
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 can inhale the cream extrusion mechanism according to the plunger displacement pump that the toothpaste requirement in the process of brushing teeth is continuously supplied with.
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 plunger displacement 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 plunger displacement pump and the toothpaste tube forms an airtight gas storehouse, and pump seat is provided with an intake valve group and an air bleeding valve group; And intake and exhaust switching self-lock switch, cylinder and plunger and plunger return spring are established in the rear end of pump seat.Intake valve group and air bleeding valve group are made up of check valve a and check valve b and check valve c and check valve d respectively; On pump seat, constitute two T shape air flue intake valve group air flues and air bleeding valve group air flue; Air flue is UNICOM gas storehouse, atmosphere and pump chamber respectively; Like Fig. 3, shown in Figure 4, the push rod of self-lock switch is provided with threeway at intake valve group duct position or air bleeding valve group duct position, with UNICOM gas storehouse, atmosphere and pump chamber; Be provided with intake and exhaust between the push rod of T shape air flue and self-lock switch and switch the self-lock switch sealing ring, the bottom of push rod is provided with self-locking mechanism.When brushing teeth, take off the brush cap, press a few lower plunger pumps and just can brush teeth; Plunger displacement pump makes pressurization in the gas storehouse, and the pressure-driven piston makes the toothpaste in the toothpaste tube pass through the toothpaste passage in the brush, gently; Continuously be transported on the bristle, brushed tooth after, click intake and exhaust and switch the self-lock switch button; Pressed gas in the toothpaste tube is discharged, in order to avoid toothpaste flows out.When filling toothpaste; Screw off brush; Switching self-lock switch to intake and exhaust presses and makes self-lock switch push rod three pass to air bleeding valve group duct position to pin; Then toothpaste mouth is screwed in the toothpaste mouth interface, press plunger displacement pump and make the air in the gas storehouse extract out produce negative pressure, move behind the piston can be toothpaste inspiration toothpaste tube thereby make.
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.Pressing plunger displacement pump can be toothpaste inspiration toothpaste tube, and filling toothpaste is easy.
