The structural design of lotion pump is one of the key factors to ensure its efficient, stable and safe operation. A well-designed lotion pump can not only effectively adapt to lotions of different viscosities, but also improve user experience and extend product life.
Pump body structural design
Material selection: The pump body material must have good corrosion resistance and wear resistance to cope with the chemicals that may exist in the lotion and wear under long-term use. Stainless steel, food-grade plastics, etc. are common choices. They are not only safe and harmless, but also effectively resist corrosion and aging.
Flow channel design: The flow channel design in the pump body should reduce resistance as much as possible and improve fluid delivery efficiency. Reasonable flow channel shape and size can reduce the friction between the fluid and the pump body and reduce energy loss. At the same time, the flow channel must also ensure that there is no dead corner, which is convenient for cleaning and disinfection, and prevents the residue of lotion from causing bacterial growth.
Sealing: The sealing between the pump bodies is crucial to prevent lotion leakage. Sealing is usually achieved by using sealing rings, sealing gaskets and other components. These components must be made of high-quality materials and precision-processed to ensure the sealing effect.
Pump head and pump core design
Pump head structure: The pump head is the part of the lotion pump that is in direct contact with the user, and its design needs to take into account the convenience and comfort of the user. The pump head usually adopts a push-type design, which drives the lotion out through the compression and recovery of the spring. The shape, size and material of the pump head must be carefully designed to ensure smooth pressing and moderate force.
Pump core structure: The pump core is the core component of the lotion pump, which is responsible for sucking the lotion out of the container and delivering it to the pump head. The design of the pump core needs to consider factors such as the viscosity, flow rate and pumping pressure of the lotion. For medium and high viscosity lotions, the pump core may use structures such as screws and gears to enhance the pumping capacity. The material of the pump core must also be corrosion-resistant and wear-resistant to ensure long-term stability.
