Abstract
The invention discloses a manual bidirectonal air pump. The air pump comprises a pump body, wherein the inside of the pump body is provided with a working chamber; the both ends of the working chamber are separately provided with a front seal plate and a back seal plate; the inside of the working chamber is provided with a piston which divides the working chamber into a front working chamber and a back working chamber; and the back end of the piston is connected with a piston rod. The key points of the technical scheme of the invention are as follows: the front seal plate and the back seal plate are separately provided with a front one-way gas outlet valve and a back one-way gas outlet valve which can outgass only from the working chamber; the inside of the piston is provided with a cavity; the front side of the cavity is provided with a front one-way gas inlet valve which is used to communicate the cavity with the front working chamber and suck air only from the front working chamber; the back side of the cavity is provided with a back one-way gas inlet valve which is used to communicate the cavity with the back working chamber and suck air only from the back working chamber; and the inside of the piston rod is provided with a connection through hole which is communicated with the cavity and connected with a sucked container.
Description
[technical field]
The present invention relates to a kind of extraction pump.
[background technique]

Aforesaid manual bidirectional extraction pump is characterized in that: the unidirectional gas outlet valve in described unidirectional gas outlet valve 6 and back 7 is made by elastic caoutchouc.
Aforesaid manual bidirectional extraction pump is characterized in that: breather cheek valve 8 and back breather cheek valve 9 are made by elastic caoutchouc before described.
Aforesaid manual bidirectional extraction pump is characterized in that: described piston rod 3 tail ends are connected with handle 10, are provided with the air passing hole 1001 that communicates with described connecting through hole 301 in the described handle 10.
Compared with prior art, the present invention has following advantage:
Can both bleed in the reciprocal process of piston of the present invention, two-way pumping efficiency height is time saving and energy saving.
