Detailed Description

For a better understanding of the present invention, reference is made to the accompanying drawings and examples, which are set forth in the following description and are incorporated in the following description.

A novel mask, comprising: gauze mask body 1, nose bridge strip 2 and elasticity ear area 3, gauze mask body 1 includes: a skin-friendly layer 101, a core layer 102, and an outer layer 103; the edges of the skin-friendly layer 101, the core layer 102 and the outer layer 103 are bonded in sequence through a thermal bonding process, and the skin-friendly layer 101, the core layer 102 and the outer layer 103 are thermally bonded after being pressed, so that the conformability among the skin-friendly layer 101, the core layer 102 and the outer layer 103 is ensured; the core layer 102 includes: a central film 1021 having air permeability and a peripheral film 1022 having air impermeability; the outer edge of the center film 1021 is bonded to the inner edge of the edge film 1022. The edge film 1022 is inexpensive and is used to block air; the center membrane 1021 serves to ventilate and filter air. The nose bridge strip 2 is made of plastic or iron, preferably plastic with iron wires, and has high plasticity. The single elastic ear band 3 is 150MM in length. The transverse two sides of the mask are provided with folds.

In addition, based on the structure of the core layer 102, the core layer 102 can be provided with the nose bridge strip 2 and the elastic ear band 3 for direct use, the skin-friendly layer 101, the core layer 102, the nose bridge strip 2 and the elastic ear band 3 can be produced and used in combination, and the skin-friendly layer 101 can be consistent with the core layer 102 in size and can also be consistent with the size of the central film 1021 in the core layer 102; the core 102, outer layer 103, nose bridge 2 and elastic ear band 3 may be used in combination, with the outer layer 103 being of the same size as the core 102 and also of the central film 1021 in the core 102. Similarly, the skin-friendly layer 101 and the outer layer 103 may be sized to be produced in various combinations with the core layer 102.

A square air vent is arranged at the central position of the edge film 1022; the central film 1021 is adhesively disposed over the ventilation opening. The specification of the ventilation port is about 4cm x 5cm, but the ventilation port is not limited to the specification, and the minimum area of the ventilation port can meet the requirement of smooth breathing of the nasal cavity and the oral cavity of a user.
