Full-plastic emulsion pump head

Abstract

The invention relates to the field of emulsion pump heads, in particular to a full-plastic emulsion pump head. A pressing head, a main column, a pump body, a bottle cap, a plastic spring and a movable pump plug are all made of plastic, and are environmental-friendly, safe and convenient to recycle; meanwhile, an elastic assembly that is adopted is a plastic spring, and a plastic ball for liquid to enter is arranged in the lower end of the pump body; and meanwhile, the problems that a metal spring and a metal ball are corroded and contents are polluted when the metal spring and the metal ball are adopted are solved. The pressing head is rotated into a blocking groove, a first-stage clamping block is used for preventing a guide strip from automatically exiting from the blocking groove, a self-locking structure is safe and reliable, and the problem of liquid leakage caused by the fact that the guide strip exits from the blocking groove due to vibration and loosening in the transportation process is solved; and in addition, according to the full-plastic emulsion pump head, a buckle can be arranged between the pressing head and the bottle cap so as to avoid the problem of liquid leakage caused by the fact that the guide strip moves along a guide groove, and therefore locking can be achieved through left-right rotation or the buckle according to the specific production condition.

Description

technical field [0001] The invention relates to the field of emulsion pump heads, in particular to an all-plastic emulsion pump head. Background technique [0002] The traditional lotion pump usually consists of a lock bottle cap, a pump chamber, a press head, a main column, an auxiliary column, a piston, a glass bead, a rebound device, and a lock cover that fixes the main column, the auxiliary column, and the piston on the pump chamber. The rebound device adopts a metal spring and is arranged in the material body cavity. When the emulsion is pumped, it is immersed in the emulsion. The metal spring is easy to corrode and pollute the content (emulsion); and because the traditional emulsion pump generally includes plastic, metal and glass, etc. Parts and components need to be disassembled and sorted for recycling during recycling, which is inconvenient to recycle. In addition, the self-locking structure on the existing lotion pump that prevents the main column from being pres...
