The emulsion spray head is a push type emulsion spray head with a plastic spring structure, a pump core assembly is formed by a spring sleeve, a pump body, a valve needle, a piston, an inner plug, a valve rod and a plastic spring of the emulsion spray head, the main innovation point is that the improvement of the pump core structure in the emulsion spray head and the technical research and development and application of high and new materials on an emulsion pump are improved, and particularly, an outer cover spring is improved into the plastic spring, so that the whole emulsion spray head can be recycled and processed without being disassembled. The main characteristics are as follows: 1. the plastic spring adopts a brand-new design, the appearance of the plastic spring is of a multi-section tower-shaped corrugated cylinder structure, the middle through hole is designed, the wall thickness of the plastic spring is extremely thin, the outer ring is in a W-shaped wave-shaped design, the concave-convex wave-shaped structure is designed to be more in accordance with the elasticity mechanics, the good elastic effect is created by product deformation, the pressing hand feeling is very soft and fine, and the traditional steel wire spring has a harder and more abrupt hand feeling. 2. The emulsion sprayer is of a full-plastic structure and is made of recyclable plastic, so that the emulsion sprayer is environment-friendly and healthy, the whole sprayer is directly recycled, and the emulsion sprayer is not required to be split, environment-friendly, low-carbon, economical, efficient and convenient.

The production and assembly are 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 outward turning 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 all-plastic pump core assembly. In the using process, the 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; the ripple barrel of the plastic spring is rebounded and reset after hands are released, the valve rod, the head cap, the piston and the valve needle are driven to move upwards, and the function of rebounding after the pump core assembly is pressed is achieved. The emulsion sprayer has the advantages that the production is convenient and fast, the all-plastic pump core assembly is used as a universal part to be independently assembled, and a finished product can be assembled by the matched large ring and the head cap, so that diversified combination is realized according to the mutual collocation of the actual requirement and different large rings and head caps, and the requirements of consumers are met. Most plastic spring structure spray heads in the market at present are integrally designed, and cannot realize a single pump core assembly full-plasticizing structure, so that a finished product of the all-plastic structure spray head can be finished only by matching a fixed large ring and a fixed head cap, and the plastic spring structure spray head is single and rigid.
