AI Technical Summary

Benefits of technology

[0009]An objective of the present invention is to provide a mask structure which can remarkably improve the production efficiency and meanwhile allow for a good waterproof effect and wearing comfort by eliminating the need of an inner waterproof ring.

[0010]To achieve the aforesaid objective, a mask structure without an inner waterproof ring provided by the present invention comprises at least one lens assembly and a first injection molded component. The first injection molded component is disposed on the periphery of the lens assembly by injection molding. The first injection molded component has a skirt portion. The inner surface of the skirt portion of the first injection molded component is a flat surface, which completely eliminates the need of the inner waterproof ring.

Problems solved by technology

However, for such a mask structure with a waterproof ring 122 disposed on the skirt portion 120 or other kinds of mask structures, the shape of the mask itself is irregular and complex, so the mold cost is relatively high.

The manufacturing process requires manual assembly operations, so labor time and mold costs are required.

This is unfavorable for rapid production on a production line and for cost control.
