Abstract
The utility model discloses a manual two-way air extracting pump, which comprises a pump body. An operating cavity is arranged in the pump body; two ends of the operating cavity are respectively provided with a front sealing plate and a rear sealing plate; a piston for dividing the operating cavity into a front operating cavity and a rear operating cavity is arranged in the operating cavity; and a piston rod is connected to the rear end of the piston. The technical scheme mainly includes that a front one-way air outlet valve and a rear one-way air outlet valve are respectively arranged on the front sealing plate and the rear sealing plate and only allow air to exit from the operating cavity, a cavity is arranged in the piston, a front one-way air inlet valve communicated with the cavity and the front operating cavity is arranged in the front of the cavity and only allows air to enter the front operating cavity, a rear one-way air inlet valve communicated with the cavity and the rear operating cavity is arranged on the back of the cavity and only allows air to enter the rear operating cavity, and a connecting through hole communicated with the cavity is arranged in the piston rod and connected with a container with air to be extracted.
Description
[technical field]
The present invention relates to a kind of extraction pump.
[background technique]
Existing manual suction pump can only be just can bleed when a direction is moved when piston, just wastes a stroke like this when pumpback, and pumping efficiency is low, wastes time and energy.
[summary of the invention]
The present invention seeks to have overcome the deficiencies in the prior art, the manual bidirectional extraction pump that can both bleed in the reciprocal process of a kind of piston is provided.
The present invention is achieved by the following technical solutions:
A kind of manual bidirectional extraction pump, comprise the pump housing 1, in the described pump housing 1, be provided with active chamber 101, described active chamber 101 two ends are respectively equipped with preceding hush panel 4, back hush panel 5, be provided with the piston 2 that it is divided into preceding active chamber 1011 and back active chamber 1012 in the described active chamber 101, described piston 2 rear ends are connected with piston rod 3, it is characterized in that: hush panel 4 before described, be respectively equipped with the preceding unidirectional gas outlet valve 6 that to give vent to anger from active chamber on the back hush panel 5, the unidirectional gas outlet valve 7 in back, be provided with cavity 201 in the described piston 2, the front side of described cavity 201 be provided be communicated with described cavity 201 and preceding active chamber 1011 can only be before described the preceding breather cheek valve 8 of air inlet in the active chamber 1011, the rear side of described cavity 201 is provided with the back breather cheek valve 9 of air inlet in the active chamber backward 1012 that is communicated with described cavity 201 and back active chamber 1012, is provided with in the described piston rod 3 and described cavity 201 connecting through holes 301 that join with extraction vessel that communicate.
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.

[embodiment]
A kind of manual bidirectional extraction pump, comprise the pump housing 1, in the described pump housing 1, be provided with active chamber 101, described active chamber 101 two ends are respectively equipped with preceding hush panel 4, back hush panel 5, be provided with the piston 2 that it is divided into preceding active chamber 1011 and back active chamber 1012 in the described active chamber 101, described piston 2 rear ends are connected with piston rod 3, it is characterized in that: hush panel 4 before described, be respectively equipped with the preceding unidirectional gas outlet valve 6 that to give vent to anger from active chamber on the back hush panel 5, the unidirectional gas outlet valve 7 in back, be provided with cavity 201 in the described piston 2, the front side of described cavity 201 be provided be communicated with described cavity 201 and preceding active chamber 1011 can only be before described the preceding breather cheek valve 8 of air inlet in the active chamber 1011, the rear side of described cavity 201 is provided with the back breather cheek valve 9 of air inlet in the active chamber backward 1012 that is communicated with described cavity 201 and back active chamber 1012, is provided with in the described piston rod 3 and described cavity 201 connecting through holes 301 that join with extraction vessel that communicate.
The unidirectional gas outlet valve in described unidirectional gas outlet valve 6 and back 7 is made by elastic caoutchouc.
Described forward direction suction valve 8 and back breather cheek valve 9 are made by elastic caoutchouc.
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.
Working principle of the present invention: promote piston 3 forward, preceding active chamber 1011 volumes diminish gradually and make preceding active chamber 1011 interior pressure increase, preceding unidirectional gas outlet valve 6 is opened, breather cheek valve 8 is closed, the in the past unidirectional gas outlet valves 6 of gas in the preceding active chamber 1011 are discharged, simultaneously because back active chamber 1012 volumes increase the formation negative pressure gradually, the unidirectional gas outlet valve 7 in back cuts out, and back breather cheek valve 9 is opened in the container air-breathing; Pull back piston 3, back active chamber 1012 volumes diminish gradually and make preceding active chamber 1012 interior pressure increase, the unidirectional gas outlet valve 7 in back is opened, the back is closed to suction valve 9, the in the past unidirectional gas outlet valve 7 of gas in the back active chamber 1012 is discharged, simultaneously because preceding active chamber 1011 volumes increase the formation negative pressure gradually, and preceding unidirectional gas outlet valve 6 cuts out, preceding breather cheek valve 8 is opened in the container air-breathing.
