Description

External pump core of spring

Technical Field

The utility model relates to a lotion pump accessory equipment technical field specifically is an external pump core of spring.

Background

The emulsion bottle and the vacuum pump are containers for storing and taking emulsion, and mainly utilize the principle of a push type micro sprayer, and a blocking piece is omitted in a head cap, so that the emulsion flows out of the head cap of the spray head after passing through a suction pipe and a pump body, and cannot be atomized and sprayed out due to the blocking of the blocking piece. The two differences mainly lie in whether a through hole is arranged on one side of the pump body and whether a suction pipe is arranged; the main structures of the emulsion bottle and the vacuum pump are an emulsion bottle cap and pump cores, wherein some pump cores adopt the structure of an external spring.

The spring of the existing pump head is arranged in the pump head, is easy to contact with liquid, pollutes the liquid and influences the use effect of the liquid, and when the spring is arranged in the pump head and is in contact with the liquid for a long time, the spring is soaked for a long time and influences the service life of the spring; the existing pump head realizes liquid discharge through the through hole on one side, the liquid discharge amount is limited in such a way, the through hole is easy to block, and the liquid discharge amount is influenced after the through hole is blocked; most of the existing pump heads are designed with outer covers as containers for containing cups and pumping out liquid, and after long-term use, residues are easily left in the liquid outlet pipe, so that the pump heads are inconvenient to use.
