Embodiment 1
[0045] A large flux double-diaphragm manual pump, including a pump body 501, both sides of the pump body 501 are sealed with an end cover 1, and the pump body and each of the end covers 1 are sealed Assemble a diaphragm 4, the pump body 501 and the end caps 1 on both sides and the diaphragm 4 are locked by a compression mechanism, and each diaphragm 4 is reciprocally deformed by the rocker drive mechanism, wherein:
[0046] A sealed drive cavity 507 is formed between the pump body 501 and the diaphragm 4, and a feed cavity 504 and a discharge cavity 506 that are not communicated with the drive cavity 507. The rocker drive mechanism The driving end is located in the driving chamber 507, and the pump body 501 is provided with a feed port 503 communicating with the feed chamber 504 and a discharge port 505 communicating with the discharge chamber 506;
[0047] Each of the end caps 1 is formed with a cavity 101, a feed channel 102 and a discharge channel 103 respectively communica...
Embodiment 2
[0054] As a preferred manner, a base 502 is fixed on the bottom of the pump body 501 , and a fixing bolt hole is provided on the base 502 . The pump body 501 and the base 502 constitute the pump body 5 of the manual pump of the present invention, and the base 502 is used for fixing the pump body 5 of the present invention.
[0055] As a preferred mode, the pump body 501 , the end cover 1 and the diaphragm 4 are matched in parallel, and the outline of the diaphragm 4 is the same as that of the inner side wall of the end cover 1 and the side wall of the pump body 501 . The cooperation of the three can form a closed cavity.
[0056] As a preferred mode, the pressing mechanism includes a pump body body positioning earring 509 fixed on the outside of the pump body body 501, an end cap positioning earring 105 fixed on the end cover 1, and passes through the pump body body positioning earring 509. And end cap positioning earring 105, the threaded connecting rod 6 that two ends utili...
Embodiment 3
[0061] The rocker drive mechanism includes a rocker structure with one end located in the drive chamber 507 and the other end passing through the pump body 501, a shaft coupling 7 driven by the rocker structure to reciprocate in the axial direction, and fixed on Both ends of the coupling member 7 are driven to deform and support the chuck I31 corresponding to the diaphragm 4 .
[0062] Manually shake the top of the rocker structure, the rocker structure drives the shaft coupling 7 to reciprocate in the axial direction, the shaft coupling is cylindrical, and when the shaft coupling 7 drives the supporting chuck I31 to move axially, the supporting chuck I31 pushes the membrane The deformation of the sheet 4 corresponds to the volume change of the concave cavity 101 and promotes the fluid flow. The supporting chuck I31 can be fixedly connected with the diaphragm 4, and when the shaft coupling 7 moves back and forth, the diaphragm 4 is deformed by pushing and pulling.
