The pump head can be divided into screw pump head, cassette pump head, left and right lock pump head, hand button type pump head (spray gun), direct press pump head with cover, and left and right with cover Lock the pump head. The hand button pump head is mainly used for detergent products, such as degreasing and glass cleaning products. According to the function, it can be divided into emulsion pump head, foam pump head, vacuum pump head, spray pump head (spray head), aerosol pump (spray head), and so on. Foam pump heads are mainly used in hand sanitizer, skin cleanser, shampoo, shower gel, and other products, especially in children's products.

    Among them, the internal structure of the foam pump head is more complicated. After the material in the bottle passes through the mesh in the foam pump head, the material is wrapped in air and made into bubbles by the fine mesh, so the foam is pressed out, and it does not need to be rubbed with water to foam, the dosage is small, and it is convenient to use. The material in the foam pump head must be liquid, and the material must be very thin and not thick, otherwise, the mesh will be blocked and the material will not be pressed out. The bottle with the foam pump head can only hold liquid but not lotion, and the fine mesh in the pump head cannot be missing, otherwise, the foam cannot be pressed.

    We can choose the pump head with the appropriate pump output according to the characteristics of the product used. For example, if the amount of shampoo, shower gel, etc. is large at one time, a pump head with a large pump output should be used. For products such as water and emulsion, use a pump head with a slightly smaller pump output. The pumping volume of the pump head should be uniform and stable. The deviation of the pump output is determined according to the user's needs and the characteristics of the pump head.
