Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a press pump head and processing equipment. Background Technology

[0002] Press pump heads are used to install on the mouth of liquid bottles to squeeze out the liquid inside. They are widely used in daily life and industrial production. However, since most press pumps use straight pipes for suction, there is a situation where residual liquid in the bottle cannot be completely sucked up and used, which wastes resources.

[0003] Chinese utility model patent with announcement number CN214987295U discloses a universal press bottle pump head, which consists of a pump body and a press-out head and a pump tube respectively installed on the upper and lower parts of the pump body. The pump tube consists of a connecting section, a universal telescopic section and a suction section connected from top to bottom. The universal telescopic section can be stretched or contracted up and down and has extensibility.

[0004] The problem with the existing technology is that users need to open the pump head from the bottle opening first, and then manually stretch the universal telescopic section of the pump tube. The residual liquid on the pump tube can easily contaminate their hands, making it inconvenient to use. Utility Model Content
