Description

Hood type anti-virus mask

The present invention relates to a hooded quarantine mask, and more particularly, to a hooded quarantine mask capable of blocking droplets using structural features while having excellent breathability by forming an open area in a position facing the wearer's respirator.

The air purification mask is a mask for filtering pollutants contained in the air such as fine dust, and the quarantine mask is a mask to block viruses discharged through the respiratory tract or to block external viruses from entering the wearer's respiratory tract. Although the purpose of the two masks are different, it is common to use an air purification mask as a quarantine mask because viruses are blocked in the process of filtering pollutants contained in the air.

The air purification mask provides purified air to the wearer by sealing the space around the wearer's respirator as much as possible from the outside and purifying the air flowing into the closed space using a fiber density or purification filter.

This air purification mask has a compact structure for sealing the space around the wearer's respirator from the outside and filtering the air flowing into the enclosed space, so it has a disadvantage in that the breathing property of the wearer is deteriorated and the wearer feels uncomfortable and tight breathing. In particular, when an air purification mask is used for quarantine purposes, it is often necessary to wear it for a longer period of time than when used for air purification purposes, and it is often necessary to wear it indoors. This becomes more prominent.

3 is an exploded perspective view of a breathing unit according to an embodiment of the present invention, and FIG. 4 is a view showing a flow path of exhalation and droplets in the breathing unit according to an embodiment of the present invention. And Figure 5 is a view showing an example of the breathing unit according to an embodiment of the present invention.

The breathing unit 100 of the mask according to the present embodiment has three or more blocking films 110 overlapped in a state spaced apart from each other as described above in order to freely pass air, sound, etc., while blocking droplets containing a virus. It is formed in a multi-layer structure.

More specifically described with reference to FIG. 3, the breathing unit 100 may include three or more blocking films 110 disposed spaced apart from each other, and a space maintaining member 130 for maintaining a separation between the blocking films 110. have. The blocking layer 110 may be formed of an impermeable material or may be formed of a filter that filters contaminants in the air. In addition, some of the blocking layers 110 may be formed of an impermeable material, and the remaining blocking layers 110 may be formed of a filter.

Each of the blocking layers 110-1, 110-2 and 110-3 is provided with through regions a1, a2, and a3 in which one or more through holes 111-1, 111-2 and 111-3 are formed, Each of the through regions a1, a2, and a3 may be disposed so as not to overlap each other between adjacent blocking layers as described above. A plurality of through regions a1, a2, and a3 may be formed in each of the blocking layers 110-1, 110-2, and 110-3.

At this time, the spaced apart spaces between the respective blocking films 110 and the through holes 111 form a connected flow path that communicates the outer space and the facial space, and the through regions a1, a2, a3 are interposed between each other. By being arranged so as not to overlap, the flow path formed is not formed in a straight line, but a path change point is formed. Here, when the wearer breathes, the flow of air is guided through the flow path formed in the breathing unit 100. The air can freely flow regardless of this even if there are multiple path switching points in the flow path, but droplets in the air Does not pass through the path transition point. In order to maximize such a splash blocking effect, in the mask according to the present embodiment, the through regions a1, a2, and a3 formed in each blocking layer may be alternately arranged vertically.

In more detail with reference to FIG. 4 as an example, when the through regions a1, a2, and a3 are alternately arranged vertically, the flow path formed in the breathing unit 100 is switched from upward to downward or downward to upward. . When the flow path shown in FIG. 4 is changed from downward to upward as an example, when the wearer exhales, it is discharged from the facial space to the external space regardless of the shape of the wearer's exhalation path, but droplets included in the wearer's exhalation are Even if it passes through the penetration area a3 of the facial-side barrier layer, it is blocked by the second barrier layer 110-2 and most of them cannot flow any more. Depending on the angle when passing through the face-side penetration region a3, some droplets may flow downward along the flow path, but the droplets flowing downward do not pass through the second penetration region a2 and accumulate on the floor. Even if a small portion of the droplet passes through the second penetration area, the passed droplet cannot move upward along the upward flow path, and thus cannot pass through the outer penetration area a1 and discharge into the external space. Of course, droplets in the air of the outer space cannot also flow into the space on the face side of the wearer through the same principle.

Due to the structural characteristics of the breathing unit 100, the mask according to the present embodiment can freely pass air, sound, and the like, while blocking droplets containing viruses, thereby facilitating the wearer's breathing and effectively blocking viruses.

Preferably, in the through region according to the present invention in order to improve the blocking effect of droplets, through holes 111-1, 111-2, and 111-3 having different shapes for each blocking film may be formed.

As shown in FIG. 5, as the number of blocking films 110 disposed on the breathing unit 100 increases, the flow path formed in the breathing unit 100 extends and the number of path switching points increases. As it increases, the splash blocking effect increases. However, as the number of blocking films 110 increases, the load of the mask increases and the manufacturing cost also increases. Therefore, rather than unconditionally increasing the number of blocking films 110, an appropriate number of blocking films 110 is provided. It is desirable to do it.

Referring back to FIG. 3, the space holding member 130 is formed in a frame shape, and a blocking film 110-2 disposed in the middle of the three blocking films may be attached to the inner circumferential surface, and the cover part 200 is attached to the outer circumferential surface. Can be. Among the three blocking layers, a blocking layer 110-1 disposed on the outside and a blocking layer 110-3 disposed on the face side may be attached to the front and rear surfaces of the space maintaining member 130.

In this case, in the mask according to the present embodiment, the space maintaining member 130 of the breathing unit 100 may be formed to be detachable from the cover unit 200 or one or more blocking films 110 may be formed to be detachable. Preferably, of the three blocking films, the outer blocking film 110-1 and the face-side blocking film 110-3 have Velcro (v1) formed around the edges, and the front and rear surfaces of the space maintaining member 130 are Velcro (v1) of the blocking film. ) Corresponding to the Velcro (v2) is formed to be coupled, the outer blocking film (110-1) and the face-side blocking film (110-3) can be attached and detached by the Velcro coupling.

As described above, in the mask according to the present embodiment, the respirator 100 or some blocking films 110-1 and 110-2 are formed to be detachable, so that it is easy to clean the part contaminated by the splash in the process of blocking the splash, and after washing It can be reused and can be used semi-permanently.
