Precise liquid distribution: the key design of liquid foundation pump to improve the user experience

In the daily makeup process, accurate liquid distribution is crucial for every user. Especially for high-viscosity and high-oil liquid products such as liquid foundation and concealer, excessive use will not only waste cosmetics, but also may cause the makeup to be too thick or uneven, affecting the overall effect. Therefore, the design of the liquid foundation pump must be able to accurately control the amount of liquid released each time it is pressed to avoid excessive or too little. Accurate liquid distribution can effectively control the amount, ensure that the use of cosmetics is more economical, and also ensure the natural and delicate makeup.

The external spring structure design of the liquid foundation pump plays a key role in ensuring the distribution accuracy. Unlike the traditional built-in spring structure, the external spring structure places the spring outside the pump body, thereby avoiding direct contact between the spring and the liquid. This design not only improves the durability and stability of the pump head, but also avoids the risk of chemical reaction between liquid and metal, ensuring the purity and safety of the liquid.

One of the core advantages of the external spring structure is that it can provide precise and consistent elastic force control at each press. The spring force is finely adjusted to ensure that the amount of liquid dispensed is kept within a precise range each time the pump head is pressed. This is especially important for oily and powder liquid foundation products, because these cosmetics have a high concentration and viscosity, and improper distribution can easily lead to waste or uneven use.

The precise control of the external spring not only ensures a more consistent amount of liquid distribution, but also effectively reduces waste each time it is used. The traditional internal spring design sometimes causes uneven distribution of liquid during the pressing process, and excessive or uneven liquid outflow not only wastes the product, but may also lead to a poor consumer experience. The external spring optimizes the adjustment of the elastic force so that a fixed amount of liquid can be released each time it is pressed, avoiding the above problems.

Especially in the field of high-end cosmetics, the precise distribution function of the liquid foundation pump directly affects the product's use effect and consumer satisfaction. Users can accurately control the amount of liquid used each time by adjusting the pressing force, ensuring that they can get just the right amount each time they apply it, avoiding the heavy makeup caused by too much application, or the poor concealing effect caused by too little application.

The design of the liquid foundation pump not only focuses on the distribution accuracy, but also on the user's convenience of operation. The application of the external spring structure makes the pump head smoother when pressed, reducing the situation of spring jamming or poor operation. The precise distribution of liquid not only depends on the control of the spring, but is also closely related to the fluid dynamics design of the pump head. The cooperation between the external spring and the pump body makes the liquid outflow more uniform and stable after each press, thereby improving the overall operation and use experience.

In addition, the precise liquid distribution also allows consumers to not worry about liquid overflow or waste caused by excessive pressing. This precise control design is especially suitable for cosmetics that require delicate application, such as liquid foundation, concealer, etc. Users can easily get the required amount by lightly pressing, without worrying about excessive or insufficient liquid during use, which greatly improves the overall convenience of use.

The liquid foundation pump can not only accurately distribute oily or powder liquids, but also adapt to cosmetic liquids of different viscosities. Because the external spring structure can provide continuous and stable elastic output, the amount of liquid distributed is not only accurate, but also can adapt to the needs of different products. For some liquids with high viscosity or containing oily components, the design of the external spring structure makes the dispensing process smoother, avoiding the blockage or failure to release smoothly that may occur in traditional pump heads.
