Pressing pump structure with waterproof ring

Abstract

The pressing pump structure with the waterproof ring comprises a pump body extending into a bottle body and further comprises a bottle locking cap, a locking cap, a pressing head, a pump chamber, an upper pump rod, a lower pump rod, a piston, a spring and a one-way valve, the bottle locking cap is connected to the pump body, the upper end of the pump body is sleeved with the locking cap, and the pump chamber is arranged on the pump body; the upper pump rod is arranged in the pump chamber and provided with a suction channel, the upper end of the upper pump rod is fixedly connected with the pressing head in an inserted mode, and the lower end of the upper pump rod is connected with the lower pump rod. A waterproof structure is arranged between the upper pump rod and the lock cover and is a waterproof ring arranged on the upper pump rod in a sleeving mode, and the upper end of the waterproof ring is in interference fit with the upper pump rod. In the whole pressing and using process, the upper end of the waterproof ring and the upper pump rod are kept in interference fit all the time, external pollutants such as water or dust are effectively prevented from entering the pump body, the risk that internal liquid is polluted and goes bad is reduced, the sealing performance of the emulsion pump is improved, and the subsequent using effect is guaranteed.

Description

technical field [0001] The invention relates to the related technical field of pressing pumps, in particular to a pressing pump structure with a waterproof ring. Background technique [0002] The application of press pumps in daily chemical products has been very extensive, but the existing press pump structure does not have waterproof function, and external pollutants such as water or dust can easily enter the inside of the pump body during use, thereby contaminating the internal liquid and causing deterioration, affecting the follow-up. use effect. SUMMARY OF THE INVENTION [0003] In view of this, one of the objectives of the present invention is to provide a press pump structure with a waterproof ring, which can effectively prevent domestic water from entering the pump body and the bottle body, and reduce the risk of contamination of the internal solution. [0004] The technical scheme that the present invention adopts for solving its technical problem is: [0005] A...
