a spray pump

Abstract

The invention relates to an atomizing pump. The atomizing pump comprises a head cap, a bottle cap, a pump body, a piston, a hoodle and a spring, wherein one side of the head cap is provided with a sprayer; the bottle cap is used for connecting the atomizing pump to a bottle body; the pump body is arranged at the lower side of the top face of the bottle cap; the lower portion of the piston penetrates through a through hole to be connected into an extruding cavity in a mode capable of moving up and down and maintain a tightly matched state with the inner wall of the extruding cavity all the time. The atomizing pump simplifies the structure of an atomizing pump in the prior art, the structure of the atomizing pump is simpler and more reasonable, the manufacturing and the assembly are convenient, therefore the production cost of the atomizing pump is reduced, and the market competitiveness of the atomizing pump is improved; meanwhile, the atomizing pump ingeniously uses the connection structure between the piston and the head cap, a seal structure is not needed to be additionally arranged, the seal of the atomizing pump is achieved, therefore, the liquid leakage problem when the bottle body is inverted is avoided, the connection between the piston and the body is simple and good in sealing performance, the liquid is pressed into a spraying cavity conveniently, the atomizing volume of the atomizing pump is large and stable, and the use is convenient.

Description

Technical field [0001] The invention relates to the technical field of micro-sprayers, in particular to a spray pump. Background technique [0002] Due to its exquisite design and convenient use, sprayers have been widely used in daily chemical and pharmaceutical industries. Due to design defects, existing sprayers often have disadvantages such as relatively slow pumping during use, and insufficient discharge volume, which cannot meet the needs of users. [0003] In order to solve the above problems, the Chinese invention patent application "A sprayer with a gripping structure for easy connection" (application number: 201310683212.X) with the application publication number CN103721881A discloses a structure that includes a sealed cup, and the sealed cup includes There is a sealing cup seat, a connecting part protruding outward is provided in the sealing cup seat, an annular groove is arranged between the connecting part and the sealing cup seat, and flanges are provided around the...

AI Technical Summary

Problems solved by technology

[0004] Although the sprayer with the above-mentioned structure can make the ejection volume relatively stable, due to its complex structure, not only is it inconvenient to assemble, but it is also easy to cause spraying failure due to a misfit between any two parts, and the complicated parts lead to a relatively high production cost of the sprayer as a whole. High, reducing the market competitiveness of the product
