Problems solved by technology
[0003] Most of the existing hydrogenation cap products are hydrogenation caps in the form of sheet metal. It is difficult to adjust the gap and surface difference between the body and the body sheet metal, and it is difficult to control, and the size retention is poor. After a period of use, it is prone to sinking, Distortion and other problems, and the parts are scattered, and the assembly is more complicated
Existing hydrogenation cap products also have some hydrogenation caps in the form of plastic, but they have complex drainage structures, such as drainage holes or drainage pipes, and complex fixing structures, mostly with 4 or more buckles. The mold is complex, the mold cost and parts cost are high
