[0031] Reference Figures 1 to 4The anti-impact pressing pump comprises a pump body 100, a pressing head 200 and a stopper 300. The pressing head 200 is movably arranged on the pump body 100 in the vertical direction and is located above the pump body 100. The stopper 300 is detachably arranged between the pressing head 200 and the pump body 100 and is used for stopping the pressing head 200 from moving towards the pump body 100. A vertical end of the stopper 300 is provided with a plug-in part 310. The pump body 100 is provided with a limiting part 110. The plug-in part 310 and the limiting part 110 are arranged opposite to each other in the vertical direction. When the pressing head 200 is pressed, the plug-in part 310 can move in the vertical direction to be plugged into the limiting part 110.

[0032] When the pressing head 200 is impacted by external impact, the pressing head 200 pushes the stopper 300 to move in the vertical direction towards the pump body 100 when the impact force makes the pressing head 200 move in the vertical direction towards the pump body 100. Finally, the plug-in part 310 is inserted into the limiting part 110 in the vertical direction. At this time, the limiting part 110 limits the stopper 300 in the horizontal direction. The pressing head 200 and the pump body 100 limit the stopper 300 in the vertical direction, so that the stopper 300 cannot be separated from the pump body 100 and the pressing head 200, thereby reducing the risk of accidental separation of the stopper 300. When the pressing head 200 is reset, the stopper 300 is moved to make the plug-in part 310 separate from the limiting part 110. At this time, the stopper 300 can be normally detached.

[0033] In the embodiment, the limiting part 110 is arranged on the pump body 100, and the lower end of the stopper 300 is provided with the plug-in part 310. The limiting part 110 is arranged on the pump body 100. When the pressing head 200 is impacted, the stopper 300 has relatively good anti-separation effect, and the processing difficulty of the pressing head 200 is not increased. It can be imagined that the limiting part 110 can also be arranged on the pressing head 200. At this time, the upper end of the stopper 300 is provided with the plug-in part 310. Or, the limiting part 110 can also be arranged on the pressing head 200 and the pump body 100. At this time, the upper and lower ends of the stopper 300 are provided with the plug-in part 310, thereby improving the effect of preventing accidental separation.

[0034] In the embodiment, the pump body 100 is provided with the sliding hole 120, the pressing head 200 comprises a main body 210 and a sliding column 220, the sliding column 220 is connected with the main body 210, the sliding column 220 is arranged in the sliding hole 120, the limiting portion 110 is located at the periphery of the hole of the sliding hole 120, and the stop piece 300 is arranged on the outer periphery of the sliding column 220 and between the main body 210 and the pump body 100. When the pressing head 200 moves vertically towards the pump body 100, the pressing head 200 is clamped with the stop piece 300 when the main body 210 and the periphery of the hole of the sliding hole 120 of the pump body 100 are moved to clamp the stop piece 300. At this time, the stop piece 300 limits the pressing head 200, the insertion portion 310 of the stop piece 300 is inserted into the limiting portion 110 of the periphery of the hole, and the risk of loosening of the stop piece 300 is reduced. The above structure realizes that the pressing head 200 can move vertically relative to the pump body 100, and the insertion portion 310 and the limiting portion 110 can be inserted and separated, and the structure is simple and easy to implement. It can be imagined that the sliding column 220 can also be arranged on the pump body 100, the sliding hole 120 can be arranged on the pressing head 200, and the sliding column 220 is arranged in the sliding hole 120. At this time, the stop piece 300 is arranged between the pump body 100 and the sliding hole 120 of the pressing head 200.

[0035] In the embodiment, the stop piece 300 is an elastic buckle, the elastic buckle is provided with a clamping hole 320, the sliding column 220 is arranged in the clamping hole 320, and the side wall of the clamping hole 320 is provided with an opening for the sliding column 220 to enter or separate from the clamping hole 320. The stop piece 300 is an elastic buckle. When the elastic buckle needs to be installed outside the sliding column 220, the elastic buckle is elastically deformed, so that the opening is enlarged to facilitate the sliding column 220 to enter the clamping hole 320, and then the elastic buckle restores the deformation. When the elastic buckle needs to be disassembled, the elastic buckle is pulled out in the horizontal direction by applying force, the elastic buckle is elastically deformed, so that the opening is enlarged to facilitate the sliding column 220 to separate from the clamping hole 320. The stop piece 300 adopts the form of an elastic buckle, and the structure is simple and easy to implement. Specifically, the elastic buckle is an integral injection molding structure, and the plastic makes the elastic buckle have good elasticity.

[0039] In the embodiment, the groove is provided with a first elastic member 400. The first elastic member 400 is provided, and when the protrusion of the stop piece 300 is inserted into the groove, the first elastic member 400 is elastically deformed. When the impact force disappears, the press head 200 is reset, and at this time, the first elastic member 400 also restores the elastic deformation, and automatically drives the protrusion of the stop piece 300 to separate from the groove. The groove is provided with the first elastic member 400, the insertion part 310 and the limiting part 110 are automatically separated, manual separation of the insertion part 310 and the limiting part 110 is not needed, and the use experience is improved. Specifically, the first elastic member 400 is an elastic ring, and can be a rubber ring or a silica gel ring and the like. It can be understood that the shape of the first elastic member 400 is matched with the shape of the groove, that is, when the groove is a strip-shaped groove, the first elastic member 400 is also a strip-shaped structure.

[0040] In the embodiment, the groove is provided with a chamfer surface 130 around the groove opening. The chamfer surface 130 is provided, the protrusion can be guided by the chamfer surface 130, and is relatively accurately inserted into the groove, and the use stability is improved.

[0041] In the embodiment, a second elastic member 500 is arranged between the press head 200 and the pump body 100, and when the press head 200 moves downward, the two ends of the second elastic member 500 abut against the press head 200 and the pump body 100 respectively and apply a force for moving the press head 200 upward.
