External spring structure of spray head of emulsion pump

Abstract

The invention discloses an external spring structure of a spray head of an emulsion pump, and relates to the technical field of emulsion pump structures. The external spring structure is characterizedin that a controlled steel wire rod is mounted on a shell on the outer side of a spring section of a pump body of the external spring structure, so that a suction pipe on the emulsion pump can achieve the purpose of more thoroughly sucking emulsion at the bottom of a bottle with a convex-surface-shaped bottle bottom. The spring external structure of the spray head of the emulsion pump comprises apump body, wherein a screw cap is installed at the top of the pump body, penetrating holes of circular through hole structures are formed in the top of a pressing cap and the top of the screw cap, the penetrating holes in the two mechanisms are located on the same vertical axis, when the pump body drives the suction pipe to be buckled and screwed on the emulsion bottle with the convex-surface-shaped bottle bottom for use, even if some emulsions at the bottle bottom are pushed from the top through the installed steel wire rod due to the structure that the bottle bottom protrudes upwards, the bottom section of the suction pipe can be bent towards one side and the bottle body inclines laterally, and then the emulsions can be sucked, so that the functional structure is improved, and the utilization rate of the emulsion in the emulsion bottle with the convex-surface-shaped bottle bottom is higher.

Description

technical field [0001] The invention relates to the technical field of lotion pumps on the top of lotion bottles, in particular to an external spring structure for a spray head of a lotion pump. Background technique [0002] Lotion pumps are widely used in cosmetic products such as shampoos, body washes, etc., for dispensing said products from containers containing these products. In order to compensate for the negative pressure generated during the pumping of the product in the container by the lotion pump, a balance air hole is provided in the lotion pump. [0003] Chinese Patent Application No. CN201620760806.5 discloses a lotion pump with parts such as a pressure head, a tooth cover, a cylinder head, and a cylinder, wherein a first sleeve is formed on the pressure head, and the first sleeve includes a first sealing structure; A second sleeve is formed on the tooth cover or the cylinder head, and a second sealing structure corresponding to the first sealing is formed on ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a spring external structure of the spray head of the lotion pump to solve the problem that after the lotion pump with the above structure is placed on the lotion bottle and used for a long time, the lotion in the lotion bottle will become less. When applying, the emulsion at the bottom of the lotion bottle is difficult to suck up through the straw of the lotion pump, especially when the bottom of some bottles is convex, the remaining emulsion at the bottom will flow to the periphery of the bottom of the bottle, and the vertical straw is difficult At this time, throwing away the lotion bottle that has not completely used up the lotion will cause waste
