Technical Field
The invention relates to a spray head of an emulsion pump, in particular to a high polymer full-plastic push type emulsion spray head and a preparation method of a material thereof.
Background
The emulsion bottle generally consists of a spray head and a bottle body, belongs to one of containers of liquid cream cosmetics, and enables the liquid cream cosmetics (emulsion) to flow out of the containers by pressing the spray head of the emulsion pump. The working principle is as follows: the volume in the bottle body is periodically increased and decreased by pressing the head cap of the spray head, so that the pressure of the liquid is increased, and the liquid in the bottle body is sucked and discharged. However, most emulsion pumps in the current market adopt steel wire springs, and the steel wire springs are inevitably subjected to chemical reaction under the soaking of liquid, so that the elastic performance of the product is affected, and the liquid is further deteriorated and polluted to influence the physical health of a user. And the spray head of the traditional steel wire spring can be recycled after the metal spring is detached during recycling, so that the recovery is extremely unfavorable, the recovery cost is high, and the process is complex. The prior emulsion pump with a steel wire spring is disclosed in Chinese patent literature, for example, application number 200910152519.0, publication date 2010, 3 months and 3 days, and the utility model name is 'emulsion pump rotary telescopic nozzle'; the prior plastic spring vacuum pump is disclosed in China patent document publication No. 201520565501.4, issued with publication date 2015.12.23, and named "a plastic spring vacuum pump". However, the plastic spring and the spray head have fewer products combined, and similar products are difficult to recycle by adopting a full plastic structure.
Disclosure of Invention
