As an important dispensing device for cosmetics, skin care products and other liquid products, the design of the spray pump has a direct impact on the product's use effect and user experience. Therefore, in the design process of the spray pump, multiple factors need to be considered comprehensively to ensure its performance, reliability and market competitiveness.

Functional design
The core function of the spray pump is to spray the liquid evenly, so the superiority of the spray effect must be ensured during the design process. Designers need to pay attention to key parameters such as the spray angle, spray distance and atomization particle size of the spray pump. The spray angle should be adjusted according to different usage scenarios so that users can easily spray the product to the target area. At the same time, the spray distance and particle size are directly related to the product's coverage and use effect. The optimal parameters should be determined through experimental data during design to meet the specific needs of different products.

Material selection
The material selection of the spray pump is crucial and directly affects the durability, chemical stability and user safety of the product. Common spray pump materials include plastics such as polypropylene and polyethylene, and metal materials such as stainless steel. Selecting corrosion-resistant and high-temperature resistant materials can ensure that the spray pump will not deform or leak during long-term use. In addition, the non-toxicity and environmental protection of materials are also important considerations in the design. Ensuring compliance with relevant regulatory requirements is a necessary prerequisite for the design.

Sealing performance
The sealing performance of the spray pump is directly related to the shelf life and safety of the product. When designing, it is necessary to ensure the matching accuracy between the various components of the spray pump (such as the nozzle, pump body and sealing ring) to prevent the entry of air and impurities, thereby avoiding oxidation or contamination of the product. The selection of sealing materials must take into account their chemical resistance and temperature resistance to ensure that a good sealing effect can be maintained under different environmental conditions.

Ergonomic design
The user experience of the spray pump is not only closely related to its functionality, but also closely related to ergonomic design. Designers should consider the comfort of holding the spray pump and the ease of operation. For example, the shape of the spray pump should conform to the natural grip of the palm, and the height and angle of the nozzle should enable the user to easily perform the spraying operation. In addition, the pressing force and stroke should also be designed to be moderate to ensure that the user feels relaxed and effortless when using it.

Adaptive design
Different cosmetics and skin care products have their own physical properties, including viscosity, density and ingredients. Therefore, the design of the spray pump needs to be adaptable to meet the needs of various formulations. For example, for products with higher viscosity, the pump body and nozzle design of the spray pump should ensure that the fluid can pass smoothly to avoid clogging. In addition, the adjustment function of the spray pump should also be designed according to the needs of different products to achieve the best spraying effect.
