The emulsion spray head is of a push type plastic spring structure, and a pump core is assembled by a spring sleeve, a pump body, a valve needle, a piston, an inner plug, a valve rod and a plastic spring, and has the main innovation point that the improvement of the pump core structure in the emulsion spray head and the technical research, development and application of a high new material on an emulsion pump, in particular the improvement of an outer cover spring into the plastic spring, so that the whole emulsion spray head can be recycled and treated without disassembly. The main characteristics are as follows: 1. the plastic spring adopts a brand new design, the appearance presents a multi-section tower-type corrugated cylinder structure, the middle through hole is designed, the wall thickness is extremely thin, the outer ring is in a W-shaped wave design, the design of the concave-convex wave structure is more in accordance with elastic mechanics, the product deformation is more facilitated to create a good elastic effect, the pressing hand feeling is extremely soft and fine, and the hand feeling of the traditional steel wire spring is relatively hard and abrupt. 2. The emulsion spray head is of a full-plastic structure and is manufactured by recyclable plastics, so that the emulsion spray head is environment-friendly and healthy, and meanwhile, the whole spray head is directly recycled, and the emulsion spray head is free of splitting, environment-friendly, low-carbon, economical, efficient and convenient.
The production assembly is as follows: the middle through hole of the plastic spring is sleeved into the cylindrical section of the valve rod, the end face of the upper sleeve opening of the plastic spring is arranged on the plane of the everting groove of the valve rod, the other end face of the lower sleeve opening of the plastic spring is arranged on the plane of the outer ring edge of the inner plug, and the outer diameter of the lower sleeve opening is sleeved on the inner diameter of the central hole of the large ring. Therefore, the plastic spring is really assembled in the pump core assembly to form the full plastic pump core assembly. In the use process, the pressure head cap is pressed to drive the valve rod to move downwards, so that the corrugated cylinder of the plastic spring is compressed and deformed; after the hand is released, the corrugated cylinder of the plastic spring is rebounded and reset to drive the valve rod, the head cap, the piston and the valve needle to move upwards, so that the rebound function is realized when the pump core is assembled and pressed. The emulsion spray head has the advantages that the emulsion spray head is convenient to produce, the full-plastic pump core is assembled as a universal piece to be assembled independently, and finished products can be assembled by adding the matched large ring and the head cap, so that the emulsion spray head can be matched with different large rings and head caps according to actual needs, realize diversified combination and meet the demands of vast consumers. Most plastic spring structure spray heads in the market at present are of integral design, and a single pump core cannot be assembled into a full-plastic structure, so that a large ring and a fixed head cap which are matched and fixed are needed to finish the finished product of the full-plastic structure spray head, and the plastic structure spray head is single and dead.
