Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses high gas permeability gauze mask. Referring to fig. 1 and 2, including locating outside dustproof filter cartridge 1 and inside gauze mask body 2, the middle part of gauze mask body 2 has set firmly inhaling valve opening 3 to the below that lies in inhaling valve opening 3 on the gauze mask body 2 has set firmly exhaling valve opening 4. The positions of the dustproof filter box 1, which are positioned in the air suction valve hole 3, are provided with air holes 11. The two ends of the mask body 2 are respectively and fixedly provided with an ear hook 5. When in use, the mask body 2 is arranged in the dustproof filter box 1, then the ear hangers 5 at the two ends of the mask body 2 are hung on ears, and the positions of the exhalation valve hole 4 and the inhalation valve hole 3 are respectively aligned to the mouth and the nose.

Referring to fig. 1, the ear-hook 5 is sleeved with an ear-protecting ring 6, and the size of the ear-hook 5 can be adjusted by adjusting the position of the ear-protecting ring 6 on the ear-hook 5, so as to meet the wearing requirements of different wearers. In order to improve the wearing comfort, the ear protection ring 6 is provided in an arc shape matching with the shape of the ear.

Referring to fig. 2 and 3, in order to facilitate the installation of the mask body 2, an annular boss 7 is fixedly arranged at the periphery of the air suction valve hole 3 on the inner side surface of the mask body 2, and a groove 8 matched with the boss 7 is formed in the inner surface of the dustproof filter box 1. The lug boss 7 is clamped into the groove 8, so that the connection between the mask body 2 and the dustproof filter box 1 can be realized. In order to facilitate the air circulation, the height of the boss 7 is larger than that of the groove 8, so that a channel which is convenient for the air circulation is formed between the suction valve hole 3 and the dustproof filter box 1.

Referring to fig. 2, a filter screen 12 is fixedly disposed in the suction valve hole 3, and the filter screen 12 is filled with purification particles. Can filter the impurity in the air in the process of breathing in, prevent that impurity from getting into the nasal cavity.

Referring to fig. 4, a sealing ring 9 is fixedly arranged at a contact position of the outer edge of the inner side surface of the mask body 2 and the face, and a sealing gasket 10 is fixedly arranged at a position of the sealing ring 9, which is positioned at the nasal alar part. The gasket 10 includes two elastomeric sheets one 101 and two elastomeric sheets two 102 arranged in a chevron formation. After the mask is worn, the sealing ring 9 can be in contact with the face, and the first elastic sheet 101 and the second elastic sheet 102 can be tightly attached to the gaps on the two sides of the nose wing, so that the phenomenon that the glasses are fogged due to the fact that exhaled water vapor seeps upwards is avoided.

Referring to fig. 2 and 5, an exhalation valve sheet 13 is fixedly arranged in the exhalation valve hole 4, and a moisture absorption sponge layer 14 is connected to the side surface of the exhalation valve sheet 13 far away from the mask body 2. The exhaled water vapor is exhausted to the outside through the exhalation valve sheet 13 after being absorbed by the moisture absorption sponge layer 14. In order to facilitate the acceleration of the discharge of water vapor, a plurality of flow guide grooves 141 are uniformly distributed on the side surface of the moisture absorption sponge layer 14 close to the exhalation valve piece 13, and a plurality of air guide hoses 15 communicated with the flow guide grooves 141 are inserted into the exhalation valve piece 13. The water vapor enters the air guide hose 15 under the guiding action of the guiding groove 141 and is discharged. Meanwhile, the moisture absorption sponge layer 14 can absorb water vapor, so that the dryness of the interior of the mask is ensured, and the muggy feeling is prevented.

Referring to fig. 5, two elastic valves 151 are fixedly arranged in the air guide hose 15, the two elastic valves 151 are both half-moon-tooth-shaped and symmetrically distributed along the inner diameter of the air guide hose 15, and the free ends of the two elastic valves 151 face the direction of the dustproof filter box 1. Because the elastic valve 151 has certain elasticity and can deform, the distance between the two elastic valves 151 can be increased when the air exhales outwards, so that the water vapor can be conveniently discharged. When inhaling, the two elastic valves 151 are attached together under the action of suction force, so that the air guide hose 15 has the function of one-way flow guide, and prevents external air from entering the inside of the mask body 2.

Referring to fig. 5, in order to facilitate the installation and replacement of the moisture absorption sponge layer 14, the moisture absorption sponge layer 14 is fixedly provided with a snap fastener 142, and the mask body 2 is provided with a buckle 21 at the outer edge of the exhalation valve hole 4, wherein the buckle 21 is matched with the snap fastener 142. The moisture absorption sponge layer 14 can be fixed to the mask body 2 by pressing the snap fastener 142 into the snap fastener 21.

The implementation principle of the high-breathability mask in the embodiment of the application is as follows: first, the snap fastener 142 is pressed into the snap fastener 21 to fix the moisture absorption sponge layer 14 and the mask body 2. Then, the boss 7 is connected into the groove 8, and the mask body 2 is mounted on the dust-proof filter box 1. Finally, the position of the ear protection ring 6 is adjusted, the ear hook 5 is hung on the ear, and the sealing ring 9 and the sealing pad 10 are respectively jointed with the face and the nasal alar. In the use process, the outside air is filtered by the filter screen 12 and then enters the inlet cover body 2 from the absorption valve hole; the exhaled water vapor is guided by the guiding groove 141 and then discharged from the air guiding hose 15.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
