Description

High-air-tightness mask

Technical Field

The utility model relates to a gauze mask technical field especially relates to a gauze mask of high gas tightness.

Background

The mask is a sanitary article, is generally worn at the mouth and nose part and is used for filtering air entering the mouth and nose so as to achieve the purpose of preventing harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer. Because the mask has a certain filtering function on air entering the lung, the mask is very important to wear when respiratory infectious diseases are prevalent and work in environments polluted by dust and the like.

However, in various masks in the prior art, because the edge of the filtering main body cannot be well attached to the face of a person, a gap exists between the filtering main body and the face of the person, so that the air tightness of the mask is poor, and the protection effect is poor.

Therefore, it is necessary to design a mask with high air tightness to solve the above problems.

Disclosure of Invention

An object of the utility model is to provide a gauze mask of high gas tightness can strengthen the gas tightness of gauze mask, improves the sense of touch of gauze mask and human skin contact.

To achieve the purpose, the utility model adopts the following technical proposal:

a high-air-tightness mask comprises a filtering main body and an ear band connected with the filtering main body; the inner side of the filtering main body is connected with an airtight sponge layer; the air-tight sponge layer is provided with a through hole for accommodating the mouth and the nose.

Further, the filter body includes an inner nonwoven layer; the edges of the air-proof sponge layer and the inner non-woven fabric layer are fixedly connected by ultrasonic bonding.

Furthermore, the filtering main body also comprises an outer non-woven fabric layer and a melt-blown fabric layer; the outer non-woven fabric layer is arranged on one side of the inner non-woven fabric layer, which is far away from the air-impermeable sponge layer; the melt-blown fabric layer is arranged between the outer non-woven fabric layer and the inner non-woven fabric layer.

Further, the thickness of the air-proof sponge layer is 3 mm-5 mm.

Further, the cross section of the through hole is circular, kidney-shaped, oval or polygonal.

Further, the air-impermeable sponge layer is a polyester sponge layer.

Further, the ear belt is a head-wearing ear belt or an ear-hanging ear belt.

The utility model has the advantages that: the high-airtightness mask has the advantages that the airtight sponge layer is arranged on the inner side of the filtering main body, and the through holes for accommodating the mouth and the nose are formed in the airtight sponge layer, so that airtightness between the edge of the filtering main body and the face of a person is enhanced, and the protection effect of the mask is better; in addition, the air-impermeable sponge layer has elasticity, so that the touch feeling of the mask in contact with the skin of a human body is greatly improved, and the mask is more comfortable to use.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 3, a mask with high airtightness comprises a filtering body 10 and an ear band 20 connected to the filtering body 10; the inner side of the filtering main body 10 is connected with an airtight sponge layer 30; the air-impermeable sponge layer 30 is provided with a through hole 31 for accommodating the mouth and nose.

Specifically, in the mask, the ear band 20 is made of elastic material, so that the mask is convenient and comfortable for a user to wear. The ear band 20 may be a head-worn ear band or an ear-hung ear band.

In the mask, a filter main body 10 includes an inner non-woven fabric layer 11; the air-impermeable sponge layer 30 is fixedly connected with the edge of the inner non-woven fabric layer 11 by ultrasonic bonding. Wherein, the inner non-woven fabric layer 11 is a PP non-woven fabric layer, and has better softness and better moisture absorption effect. The air impermeable sponge layer 30 is preferably a polyester sponge layer. Of course, sponge layers made of other materials can be adopted, and the sponge layer is air-impermeable. Wherein the thickness of the air-impermeable sponge layer 30 is 3 mm-5 mm. The section of the through hole 31 formed on the air-impermeable sponge layer 30 is circular, kidney-shaped, oval or polygonal. Of course, other shapes of through holes can be designed as long as the mouth and nose of a person can be accommodated.

Further, the filter body 10 further includes an outer non-woven fabric layer 13 and a meltblown fabric layer 12; wherein, the outer non-woven fabric layer 13 is arranged on one side of the inner non-woven fabric layer 11 far away from the air-impermeable sponge layer 30; the meltblown layer 12 is provided between the outer nonwoven layer 13 and the inner nonwoven layer 11. Preferably, the outer non-woven fabric layer 13 is a PP waterproof non-woven fabric layer, and has a good waterproof effect; the melt-blown cloth layer 12 is a single layer or a plurality of layers and has a better filtering effect.

In addition, a nose bridge strip (not shown) can be embedded in the filtering main body 10 of the mask for shaping the mask at the nose bridge, so that the comfort and the sealing performance of the mask are improved.

The high-airtightness mask of the utility model has the advantages that the airtight sponge layer 30 is arranged on the inner side of the filtering main body 10, and the through holes 31 for accommodating the mouth and the nose are formed in the airtight sponge layer 30, so that the airtightness between the edge of the filtering main body 10 and the face of a person is enhanced, and the protection effect of the mask is better; in addition, because the air-impermeable sponge layer 30 has elasticity, the touch feeling of the mask contacting with the skin of a human body is greatly improved, and the mask is more comfortable to use.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
