The atomization principle of the cosmetic pump head is the core part of its design, which is related to the spray effect and user experience of the product.

Pneumatic driving principle:

Pneumatic system: The pump head of a cosmetic pump usually contains a pneumatic system, which includes a pneumatic chamber. When the user presses the pump head, air is pushed into this air pressure chamber, creating pressure.

Spray hole connection: The air pressure system is connected to the spray hole, and the air pressure is transmitted to the spray hole through a series of pipes and channels.

Spray hole design:

Spray hole shape: The shape of the spray hole has a direct impact on the atomization effect. Usually small and evenly distributed pore sizes are used to ensure that liquid cosmetics can be evenly atomized.

Number and arrangement of spray holes: The number and arrangement of spray holes need to be considered in the design to achieve an overall uniform atomization effect. Different pump head designs may have different arrangements, such as circular, linear, etc.

Air pressure transfer:

Air pressure chamber: The air pressure chamber is a key part of the pump head. When the user presses the pump head, the air is compressed in the air pressure chamber. This pressure is transferred to the liquid through a pipe connected to the liquid storage chamber.

Piston design: The process of air pressure transmission usually involves a piston. The design of the piston needs to ensure that air can enter the air pressure chamber smoothly while preventing liquid from entering the air pressure chamber.

Liquid storage room:

Liquid filling: Cosmetic pumps usually contain a liquid storage chamber that contains the cosmetic product. When air pressure is transferred to the liquid storage chamber, the pressure forces the liquid to flow through the pipe toward the spray hole.

Liquid back-suck prevention: Mechanisms to prevent liquid back-sucking need to be considered in the design to ensure that liquid is not re-sucked into the liquid storage chamber after use to prevent contamination.

Atomization effect control:

Air pressure adjustment: The design of the pump head may contain some adjustment mechanisms through which the user can adjust the air pressure, thereby affecting the intensity and fineness of the spray.

Spray volume control: Control the speed and amount of liquid entering the spray hole through design to achieve precise control of the spray volume.
