How does the external lotion pump maintain stability in temperatures ranging from -15°C to 40°C?

An external lotion pump is a pump specially designed for dispensing water-based, lotion and non-oily liquid raw materials. One of its core advantages is that it can maintain the stability of product functions in a temperature range of -15°C to 40°C. This temperature adaptability enables it to ensure normal liquid output in various complex environments and meet users' high requirements for product performance.

First of all, the stability of this lotion pump is due to its unique design, especially the external spring structure it adopts. Traditional lotion pumps usually place the spring inside the pump body in direct contact with the liquid. However, this design has potential risks, that is, the liquid in the pump body may react chemically with the metal spring, especially in an environment with large temperature fluctuations, which may cause the composition of the liquid to be destroyed, thereby affecting the use effect and safety of the product.

In addition, the material selection of the external lotion pump has also been carefully considered. The pump head is made of food-grade raw materials, which have tolerance in both low and high temperature environments, and can effectively resist the erosion of the external environment to the pump body, thereby ensuring that the pump body can maintain a stable working state under temperatures. Food-grade materials also ensure the purity of liquid raw materials, whether in low-temperature freezing environments or in high-temperature and humid environments, to avoid harmful reactions of materials and ensure the safety and service life of the product.

The external lotion pump is not only carefully designed in terms of materials and structure, but also equipped with left and right locking structures and outer cover designs. These designs not only help prevent accidental leakage during transportation, but also further enhance the stability of the product in temperature fluctuations. The left and right locking structures can effectively lock the pump head when not in use to prevent the pump head from accidentally starting due to external forces; the outer cover provides an additional layer of protection to avoid direct impact of the external environment on the pump head. This multi-layer protection mechanism allows the spring and other internal components of the lotion pump to avoid failure problems caused by cold shrinkage or ice even in low-temperature environments;

At the same time, the external lotion pump is also specially equipped with anti-drop and transportation safety clips. These designs not only provide additional safety during transportation, but also ensure the robustness of the product under temperature conditions. The anti-drop design can protect the pump body in the event of an accidental collision and prevent the pump head components from being displaced or damaged due to vibration or impact; the transportation safety clip plays a role in fixing the pump head during transportation, ensuring the stability of the pump head during transportation and avoiding loosening or deformation of materials due to temperature changes, thereby ensuring that the product remains in the condition when it reaches the user.
