Technical Field

[0001] The utility model relates to a pressing pump, in particular to a pressing pump capable of adjusting the air pressure of a bottle body. Background Art

[0002] When the bottle is filled, the internal air pressure of the bottle is low. When it is transported to the market, as the external air pressure increases, the pressure difference can easily cause the bottle to deform.

[0003] However, the existing compression pump lacks a structure for regulating and balancing the air pressure inside the bottle. The air pressure of the bottle changes greatly from filling to transportation to the market, and the bottle is easily deformed.

[0004] Therefore, there is an urgent need for a press pump that can adjust the air pressure and improve the problem of bottle deformation. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the present utility model is to provide a pressing pump that can adjust the air pressure and improve the problem of bottle deformation.

[0007] As a further improvement of the above technical solution, a step is provided on the main body, the screw cover is fixedly installed on the step, the step includes a horizontal part and a vertical part, the vent is provided at the connection between the horizontal part and the vertical part, and there is a first gap between the screw cover and the vertical part.

[0008] As a further improvement of the above technical solution, a limiting portion is provided on the outer periphery of the vertical portion, and the limiting portion overlaps with the projection of the screw cover in the vertical direction. There is a second gap between the limiting portion and the screw cover, and the external air passes through the second gap, the first gap, the vent hole and the cavity from the outside to the inside in sequence.

[0009] As a further improvement of the above technical solution, the cross section of the flexible portion is in the shape of a downwardly curved arc.

[0010] As a further improvement of the above technical solution, the main body includes a main body and a clamping member that are detachably connected, the step is arranged on the main body, the flexible part is arranged on the clamping member, and the clamping member is clamped under the step.

[0011] As a further improvement of the above technical solution, the vent includes an inner annular wall and an outer annular wall, the clip is attached to the outer periphery of the outer annular wall, and the flexible portion passes over the vent from the bottom of the outer annular wall and abuts against the lower end of the inner annular wall.

[0012] As a further improvement of the above technical solution, there are several vents, and the flexible portion is annular.

[0013] The beneficial effect of the present invention is as follows: the present invention provides a vent hole and a flexible portion on the main body, the flexible portion abuts against the bottom of the vent hole and blocks the vent hole. When the external environmental air pressure is greater than the internal air pressure of the bottle body, the flexible portion is subjected to downward pressure and opens the vent hole, thereby regulating and balancing the air pressure in the bottle body, and improving the problem of bottle deformation caused by air pressure changes.
