Pressing pump capable of preventing residues from dripping

Abstract

The invention discloses a pressing pump capable of preventing residues from dripping, relates to the field of plastic products, and solves the problem that since most of the pump nozzles of existing hand pumps face downwards, after liquid is extruded through pressing, under the action of gravity, liquid remaining in the pump nozzles can flow out after a long time to pollute a bottle body or a place in which bottles are held. A barrier film is arranged in a pump nozzle. The shape of the barrier film is matched with that of the inner cavity of the pump nozzle and the inner cavity of the pump nozzle is isolated into a left part and a right part by the barrier film. The barrier film is cut along the center to form a multi-petal structure. When being impacted by the pressure of the liquid pumped out from the hand pump, the multi-petal structure is automatically opened to enable the liquid to flow out, and after pressure release, the multi-petal structure is automatically recovered by meansof elasticity and the pump nozzle is sealed, so that remaining liquid is prevented from continuously flowing towards, and the problem that the liquid remaining in the pump nozzle can flow out after along time to pollute the bottle body or the place in which the bottles are held is solved. The pressing pump adopting the scheme is simple in structure, low in cost, convenient to operate, and wide inpopularization prospect.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a pressing pump for preventing residual dripping. Background technique [0002] Pressing pump, also called hand pump, is a device that can use hand pressing to suck out the liquid in the bottle by air pressure. This device is widely used in cleaning fields, such as shampoo, shower gel, hand sanitizer, etc. Currently, cleaning Most of the products use a push pump to pump out the liquid. Most of the pump nozzles of the existing hand pumps face downward. After the liquid is squeezed out, due to the gravity, the liquid remaining in the pump nozzle will flow out after a long time, causing the bottle body or the place where the bottle is placed to be soiled. Contents of the invention [0003] In order to solve the above problems, the present invention provides a press pump to prevent residual dripping, which is realized by the following technical solutions: [0004] A pressing pump ...
