Macromolecular fully-plastic press-type vacuum spray head and material preparation method thereof

Abstract

The invention relates to a macromolecular fully-plastic press-type vacuum spray head and a material preparation method thereof. The macromolecular fully-plastic press-type vacuum spray head is designed to solve the technical problem that a spring structure of an existing similar product is difficult to recycle overall. A spiral slotted hole is formed in a rotating ring inside an outer cover of thevacuum spray head, a pin column of a large ring is inserted into a cover positioning groove in the inner wall of the outer cover through the spiral slotted hole in the rotating ring, a pump core assembly is fixed to a center hole of the large ring in a buckled mode, and the outer circle of a valve rod of the pump core assembly is provided with a spring. According to the key points of the macromolecular fully-plastic press-type vacuum spray head, the spring is a plastic spring, one end of the plastic spring is provided with an outer sleeving opening, one end of the plastic spring is provided with an inner sleeving opening, and a wavy cylinder is arranged between the outer sleeving opening and the inner sleeving opening of the plastic spring; and the outer sleeving opening, the inner sleeving opening and the wavy cylinder of the plastic spring are integrally formed, the two ends of the plastic spring abut against a head cap and the large ring respectively, that is, the outer circle of the outer sleeving opening of the plastic spring is in sleeving fit with the inner circle of a rib groove in the bottom in the head cap, a ring opening of the inner sleeving opening of the plastic spring abuts against a ring groove in the bottom of a large ring groove of the large ring, and the plastic spring is located in the large ring groove of the large ring.

Description

Technical field [0001] The invention relates to a spray head of a press type micro sprayer, which is a polymer all-plastic press type vacuum spray head and a material preparation method thereof. Background technique [0002] The nozzle of the micro sprayer is a plastic product used for cosmetic spraying, and the nozzle of the press type micro sprayer is a nozzle that is used for spray operation by pressing the head cap. Its working principle is: by pressing the head cap movement of the nozzle, the volume of the bottle body is periodically increased and reduced, so that the pressure of the liquid is increased, and the liquid in the bottle body is sucked and discharged. However, most lotion pumps on the market currently use wire springs. When the wire springs are immersed in liquid, chemical reactions will inevitably occur, which will affect the elastic performance of the product, and make the liquid deteriorate and pollute the user's health. In addition, the traditional wire spri...

Problems solved by technology

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a polymer all-plastic press-type vacuum nozzle and its material preparation method in the field, so that it can solve the problem of the poor structure of the nozzle in the existing similar products, especially the spring structure in the nozzle. Poor design makes it difficult to recycle as a whole, and technical problems that the material preparation method needs to be improved
