Mask Structure Without an Inner Waterproof Ring

Abstract

A mask structure that has one lens assembly and a first injection molded component, while not having an inner waterproof ring, is provided. The first injection molded component is disposed on the periphery of the lens assembly, and has a skirt portion with an inner surface that is flat without the need of providing an inner waterproof ring.

What is claimed is: 
     
         1 . A mask structure without an inner waterproof ring, comprising:
 at least one lens assembly; and   a first injection molded component, being disposed on a periphery of the at least one lens assembly by injection molding, and the first injection molded component has a skirt portion;   wherein an inner surface of the skirt portion is a flat surface without the inner waterproof ring.   
     
     
         2 . The mask structure without an inner waterproof ring as claimed in  claim 1 , further comprising two buckling members being fixed with the at least one lens assembly. 
     
     
         3 . The mask structure without an inner waterproof ring as claimed in  claim 2 , wherein the two buckling members are formed integrally with an outer edge of the at least one lens assembly. 
     
     
         4 . The mask structure without an inner waterproof ring as claimed in  claim 2 , further having a strap which is provided to connect the two buckling members. 
     
     
         5 . The mask structure without an inner waterproof ring as claimed in  claim 1 , wherein the at least one lens assembly is a single lens assembly. 
     
     
         6 . The mask structure without an inner waterproof ring as claimed in  claim 1 , wherein the at least one lens assembly is two lens assemblies. 
     
     
         7 . The mask structure without an inner waterproof ring as claimed in  claim 1 , wherein the first injection molded component is made of a material selected from the group consisting of silicone, thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), polyvinyl chloride (PVC) and combinations thereof. 
     
     
         8 . The mask structure without an inner waterproof ring as claimed in  claim 1 , wherein the at least one lens assembly is formed by a second injection molded component. 
     
     
         9 . The mask structure without an inner waterproof ring as claimed in  claim 8 , wherein the second injection molded component is made of a material selected from the group consisting of polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polypropylene (PP) and combinations thereof. 
     
     
         10 . The mask structure without an inner waterproof ring as claimed in  claim 9 , further comprising a frame for receiving the at least one lens assembly therein. 
     
     
         11 . The mask structure without an inner waterproof ring as claimed in  claim 1 , wherein the at least one lens assembly is delivered to a mask mold by an automated mechanical arm, and then the first injection molded component is formed on the periphery of the at least one lens assembly by injection molding. 
     
     
         12 . The mask structure without an inner waterproof ring as claimed in  claim 1 , wherein the at least one lens assembly is delivered to a mask mold in a manual transferring mode, and then the first injection molded component is formed on the periphery of the at least one lens assembly through injection molding.
