AI Technical Summary
In the prior art, the fluorine reflective film made of polytetrafluoroethylene material is machined and molded by rod material, resulting in high processing costs and poor water pressure resistance or air pressure resistance, limiting its application range.
Using the secondary injection molding method, the fluorine reflective film is wrapped outside the mold core and molded on its outer layer to form a cylindrical member. The interlocking structure of the buckle holes and buckle feet is simplified and the wrapping process is passed through plastic. The material improves the performance of the outer layer.
The processing cost of the components is reduced and the pressure resistance is significantly improved, making the fluorine reflective film member suitable for sterilization devices requiring high pressure resistance.

[0002] The fluorine reflective film made of polytetrafluoroethylene has excellent light reflection performance, which makes it suitable for devices that require light reflection, such as devices that use deep ultraviolet rays to sterilize water. By setting a fluorine reflective film on the side wall of the sterilization chamber, the deep ultraviolet rays can be reflected very effectively. The fluorine reflective film used in devices such as water sterilization and disinfection usually needs to be formed into a cylindrical shape to form a sterilization chamber surrounded by the fluorine reflective film, and the fluorine reflective film is usually sleeved in a cylindrical outer structure to support the fluorine reflective film through the outer structure. In the prior art, the fluorine reflective film with a hollow cavity is mainly formed by rod machining. The fluorine reflective film formed by rod machining not only has a high processing cost, but also has poor water pressure or air pressure resistance, which limits its scope of application.
