The invention discloses a spray pump sealing cup and locking cover matching structure and a spray pump. The spray pump sealing cup and locking cover matching structure comprises a spray pump sealing cup comprising a sealing cup seat; the lower end of the sealing cup seat is provided with an inward convex connection ring, the upper end of the inward convex connection ring is provided with a flange, a locking cover is connected to the inward convex connection ring in an inserted manner, the lower end of the locking cover is provided with a positioning outward convex ring, the other wall of the locking cover is provided with a buckling line locking the locking cover to the flange, the positioning outward convex ring is pressed to the bottom of the flange, and the buckling line is arranged on the upper end surface of the flange in a buckled manner. The purpose of overcoming the defects of the prior art can be achieved, and the structure is simple and convenient to assemble; the invention further aims to provide the spray pump with the structure.
Description
technical field [0001] The invention relates to a matching structure of a sealing cup and a locking cover of a spray pump, and also relates to a spray pump including the matching structure of the sealing cup of a spray pump and a locking cover. Background technique [0002] Due to its exquisite design and convenient use, the spray pump has been widely used in daily chemical and pharmaceutical industries. The existing spray pump has a relatively complicated structure, especially the structure of the spray pump sealing cup and locking cover is relatively complicated, the assembly is troublesome, and the sealing performance is not good. [0003] Therefore, the matching structure between the sealing cup and the locking cover of the existing spray pump and the corresponding spray pump need to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a structure that is simple in str...
