At the dynamic sealing of wall.It is generally sealed using O-ring seals, this kind of movable sealing structure is caused close using rear easy to wear for a long time
Seal bad or leakage so that pump cannot normally launch liquid detergent and softener, and O-ring seals at the dynamic sealing of the structure
Friction noise it is big, short life.
How preferably to solve to launch the bull pump of liquid detergent and softener poor sealing, friction noise be big and short life
The problem of, become the double end for being traditionally used for launching laundry washer liquid and softener when previous very serious technical problem
Pump cannot preferably meet the industry needs of continuous development.
Utility model content
To solve the above problems, a kind of good seal performance of the utility model offer, friction noise are small, use with long service life
In the bull pump for launching laundry washer liquid and softener, specific technical solution is：
Bull pump for launching laundry washer liquid and softener, including the pump housing, check valve, small sealing ring, check valve
Fixed plate, large sealing packing ring, cylinder body, cylinder body fixed frame, dynamic sealing, piston, gear-box, cam, gear and motor, the dynamic sealing
Sealing sharp angle α is formed with ontology, upper lip, upper lip sealing surface and lower lip, between the upper lip sealing surface and the body surface,
Lip acute angles beta is formed between the upper lip and the lower lip, the piston has slot hole, piston head, piston head inner cavity and piston
Head groove, the dynamic sealing are mounted in the piston head groove, and the upper lip sealing surface of the dynamic sealing and the cylinder body
Inner wall form dynamic sealing face.
Preferably, the projecting shaft of the motor is connect with the centre bore of the gear, and the gear is connect with the cam,
The cam is connect with the slot hole of the piston.
Preferably, the cylinder body has, the pistons of corresponding described two cylinder bodies also there are two, and it is described two
Cylinder body is integrally formed by plastic injection.
Preferably, there are two the piston head grooves of the piston, the dynamic sealing of the corresponding piston head groove
There are two, and the upper lip of described two dynamic sealings is opposite liftoff in described two piston head grooves.
Preferably, the dynamic sealing is made of rubber.
Preferably, the piston is shaped by plastic injection.
Preferably, between formation sealing sharp angle α is 10 °~20 ° between the upper lip sealing surface and the body surface.
Preferably, between the lip acute angles beta formed between the upper lip and the lower lip is 15 °~25 °.
Preferably, the motor is permanent magnetism bidirectional reversible synchronous motor.
Preferably, a cylinder body in described two cylinder bodies launches liquid detergent, another cylinder body launches softener.
According to said program it can be seen that the utility model has the following advantages that：Due to the presence of α angles, piston motion mistake
The upper lip sealing of dynamic sealing to lip direction towards rebounding simultaneously in inboard wall of cylinder block extrusion process in journey, and depositing due to β angles
And the interference volume between the upper lip sealing surface of dynamic sealing and inboard wall of cylinder block can be being automatically adjusted, when α takes 13 ° β takes 20 ° simultaneously
To be best, the dynamic sealing performance of upper lip sealing surface and inboard wall of cylinder block is ensured that in this way, while during reducing piston motion
Friction noise at dynamic sealing, and extend the service life of pump.
