What Role Does the External Spring Structure Play in the Liquid Foundation Pump's Performance?

Basic Design of External Spring Structure
The external spring structure of Liquid Foundation Pump is a unique design. Compared with the traditional internal spring design, the biggest advantage of the external spring structure is that it avoids direct contact between the liquid and the metal spring. The traditional internal spring structure exposes the spring directly to the liquid. As the number of uses increases, the metal spring may corrode or react chemically with the liquid, thus affecting the quality of the liquid and the service life of the pump head.

Key Design to Improve Liquid Safety
The external spring structure of Liquid Foundation Pump plays an important role in the safety of the liquid. For cosmetics such as oily and powdery liquids, the liquid ingredients may react with metal parts, resulting in changes in the product ingredients and even affecting the use effect. The design of the external spring structure completely eliminates the direct contact between the liquid and the spring, ensuring that the original ingredients of the liquid are not disturbed by external factors, maintaining its purity and stability.

Extended service life and reduced wear
The design of the external spring structure not only improves the safety of Liquid Foundation Pump, but also plays an important role in service life. Since the metal spring is not directly exposed to the liquid, the frequency of contact between the spring and the liquid is reduced, which greatly improves the corrosion resistance and wear resistance of the spring. Compared with the problems of spring rust, deformation or breakage that may occur in traditional designs, the design of the external spring structure can better ensure the stability and performance of the pump head in long-term use.

Accurately distribute liquid and improve the use experience
The design of the external spring structure also has significant advantages in the operating performance of the Liquid Foundation Pump. One of the functions of the Liquid Foundation Pump is to accurately control the amount of liquid distributed to avoid excessive use or waste. The external spring structure ensures that the pump head can evenly and stably distribute a small amount of liquid each time it is pressed by finely adjusting the elastic force of the spring.

In addition, the design of the external spring also helps to improve the response speed of the pump head, allowing users to quickly get the required liquid when pressing, avoiding the situation of unsmooth pressing or slow response that may occur in traditional built-in spring designs. This precise control allows consumers to better control the amount used each time, avoiding excessive or insufficient liquid distribution, and better meets the use needs of cosmetics.

Prevent spring loosening and ensure long-term stability
Another advantage of the external spring structure is that it can effectively prevent the spring from loosening or shifting. In the traditional internal spring design, the spring may loosen or shift due to the mutual friction of the internal components during long-term use, resulting in unsmooth operation of the pump head. The external spring structure ensures that the spring always stays in place through a precise fixing design, and the stability of the spring will not be affected even after long-term repeated use.
