The pump head structure of a Lotion Pump is one of its key components, which directly affects the distribution effect and user experience of the product.

Press button:

The outermost part of the pump head is the push button, also known as the pump head button. This is the primary interface through which users interact with the Lotion Pump, initiating the liquid dispensing mechanism by pressing a button. Press buttons are usually designed ergonomically to ensure easy and comfortable operation by the user.

Spring device:

Inside the pump head, next to the push button, there is usually a spring device. This spring is responsible for providing feedback and push force. When the user presses the button, the spring is compressed, storing energy. When the button is released, the spring quickly deploys, pushing other components to perform liquid dispensing.

piston:

The piston is the moving part within the Lotion Pump pump head. It works in conjunction with the spring and is responsible for generating positive thrust during liquid dispensing. Usually, the piston is a sealed cylinder that fits against the inner wall of the pump head. When the spring is released, the piston moves downward, pushing liquid through the outlet of the pump head.

exit:

The bottom of the pump head is the outlet through which the liquid is released to the outside. The design of the outlet takes into account the viscosity and consistency of the liquid as well as the user's desired dispense volume. Typically, the outlet is equipped with a valve control system to ensure that it remains sealed and prevents liquid leakage when not in use.

Seal ring:

To prevent liquid leakage and outside air from entering, the pump head usually contains a sealing ring. This is an annular seal located at a strategic location on the pump head, usually between the piston and pump head. The selection and design of the sealing ring is crucial to ensure the hygiene and product stability of the Lotion Pump.

Pump head housing:

The entire pump head is usually made of corrosion- and chemical-resistant materials, such as plastic or metal. The design of the housing must not only consider aesthetics, but also ensure that it is strong and durable enough to adapt to a variety of environmental and usage conditions.
