Embodiment Construction

[0013] Combine below figure 1 with figure 2 Illustrate this embodiment, the present invention relates to the field of protective mask structure, more specifically a kind of novel air valve film mask, comprising mask body 1, one-way breathing valve 2 and lanyard 3, can provide a kind of use PE plastics to make The air valve film replaces the breathing valve, which can further reduce the production cost of the mask, improve the breathing efficiency, improve the wearing comfort of the mask, and increase the effective use time of the mask.

[0014] The material of the one-way breathing valve 2 is PE, and ultrasonic welding is adopted between the one-way breathing valve 2 and the mask body 1 .

[0015] When in use, the one-way breathing valve 2 is made of soft PE material, which is light in weight and low in cost. It is easy to use, which can further reduce the production cost of the mask, improve the breathing efficiency, improve the wearing comfort of the mask, and improve the...

Abstract

The invention relates to the field of protective mask structures, in particular to a novel air valve membrane mask, which comprises a mask body 1, a one-way breather valve 2 and a hanging belt 3, an air valve membrane made of PE (polyethylene) plastics can be provided to replace a breather valve, the one-way breather valve 2 is made of PE, and the one-way breather valve 2 is welded with the mask body 1 by ultrasonic waves. The production cost of the mask can be further reduced, the breathing efficiency is improved, the wearing comfort of the mask is improved, and the effective use time of themask is prolonged.

Description

technical field [0001] The invention relates to the field of protective mask structure, more specifically a novel air valve membrane mask. Background technique [0002] Polyethylene polyethylene, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, and the lowest operating temperature can reach -100~-70°C. It has good chemical stability and can withstand most acids and alkalis. It is not resistant to oxidizing acids. . It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation. The breathing valve is usually made of plastic with a silicone film in the middle. The cost is high, the installation is complicated, and the efficiency of blocking air is not high, so a new type of air valve membrane mask is desig...
