Abstract

The utility model provides a vacuum sucking structure consisting of a collecting cylinder, a lower three-way base, a pump, a piston, a handle pipe, an upper three-way base, a safety valve seat, a safety valve movable bolt, a C-shaped buckle, a buoy, a collecting cylinder cover, a handle, an air vent opening, an air vent opening cover, a collecting hole cover and a sucking pipe. The vacuum sucking structure aims to discharge air from the hollow handle when the piston pushed (drawn) by the handle in the sucking structure does reciprocating motion, so that the air in the collecting cylinder is reduced, the suckling pipe is placed in liquid to be sucked, and the liquid is sucked into the collecting cylinder by the sucking pipe through an atmospheric pressure for balancing a pressure insides the cylinder when the pressure inside the cylinder is lower than the atmospheric pressure outsides the cylinder; and therefore, the function of sucking the liquid is further realized; and the operation efficiency of sucking is improved by the reciprocating motion of the handle.

Description

Vacuum suction arrangement

[technical field]

The utility model relates to a kind of vacuum draw knot, refers to a kind of vacuum suction arrangement that liquid is used that extracts especially.

[background technique]

Existing vacuum suction arrangement; Be all to be provided with an one-way air pump in the central position of a hollow storage tube; And the suction port of this one-way air pump is connected with the top of storage tube; Detach the air in the storage tube by the one-way air pump, form the negative pressure state in the storage tube, so that liquid-absorbent to storage tube inside is stored; But the article of commonly using have following all points and do not conform in practicality:
