1.Plastic spray nozzles are spray nozzles used for liquid or gas spraying, consisting of components such as the nozzle, spray orifice, and filter screen.

Plastic spray nozzles have extensive applications across various fields, including cosmetics, medicine, agriculture, and industry.
In the cosmetics industry, plastic spray nozzles are commonly used for spraying liquid cosmetics such as lipstick, perfume, and toner.
In the medical field, they are used in medical instruments like syringes and aerosol sprayers.
In agriculture, plastic spray nozzles are employed in irrigation and crop protection.
In industrial settings, they are used for tasks such as cleaning, painting, and coating.

2. Structural Composition
   A plastic spray head is primarily composed of several components such as the nozzle, valve, plunger, and spring.
   The nozzle, as the core component of the spray head, determines the shape and flow rate of the liquid being sprayed.
   The valve controls the flow of the liquid, while the plunger and spring ensure the opening and closing of the valve.
3. Working Principle
   The working principle of plastic spray nozzles is to spray liquid or gas through pressure. When the liquid or gas enters the nozzle, it is sprayed out through the spray hole due to the change in pressure. Factors such as the size, position, and number of the spray holes in the nozzle will all affect the flow rate and spraying effect of the liquid or gas.
