Why does the External Spring Cleansing Oil Pump with an external spring structure effectively improve the safety and stability of the product?

When designing an External Spring Cleansing Oil Pump, the use of an external spring structure is an important innovation. It effectively solves the problem of contact between the material body and the metal spring, thereby improving the safety and stability of the product. The core concept of this design is to remove the spring from the traditional built-in structure and place it outside the pump body, thereby achieving complete isolation of the material body and the metal spring.
1. The design of the external spring structure fundamentally avoids direct contact between the material body and the metal spring. In traditional oil pump designs, the spring is usually located inside the pump head and in direct contact with the material body. This design may cause a chemical reaction between the material body and the metal spring during use, especially in some special environments, such as temperature changes or complex material composition. This reaction may be more intense, affecting the quality and safety of the product. The External Spring Cleansing Oil Pump completely solves this problem by moving the spring to the outside of the pump body, ensuring that the material body will not contact the metal spring during use, thereby avoiding the occurrence of chemical reactions.
2. The external spring structure also improves the durability and stability of the oil pump. Since the spring is no longer in direct contact with the material body, it will not be affected by the composition of the material body, thereby extending the service life of the spring. This design also reduces the complexity inside the pump head, making the pump head structure simpler and reducing the possibility of failure. In abnormal environments, such as large temperature changes, the External Spring Cleansing Oil Pump can still maintain stable functions to ensure the normal use of the product.
3. The design of the external spring structure also improves the safety of the product. In some special application areas, such as the use of liquids such as makeup remover oil, hair oil and essential oil, the safety of the material body is particularly important. The External Spring Cleansing Oil Pump completely eliminates the risk of chemical reactions by avoiding contact between the material body and the metal spring, thereby ensuring the safety of the material body. This design also improves the compatibility of the product, allowing the External Spring Cleansing Oil Pump to be widely used in various oily liquids to meet the needs of different customers.
