Abstract

In the conventional dust mask, the air in the inside of the room is exhausted to the mask body rather than to the exhaust valve attached to the dust mask, so that the mask wears during the winter season and the safety glasses worn for work safety The fogging phenomenon was severe and inconvenient, and the moisture in the breathing air was condensed in the mask main body, and the water was frosted, making it impossible to wear the mask for a long time.
In order to achieve the above object, according to the present invention, as shown in Figs. 1 and 2, the inner surface of the exhaust valve 3 is tapered (stepped) (5) in the shape of a flare-like mouthpiece.
If the mouthpiece connected to the exhaust valve is worn lightly with the lips part (placed between the lower two lips) after spitting the above-mentioned dust mask, and spitting only the breathed breath into the mouth, It is possible to solve all the inconveniences caused by wear of the dust-proof mask (such as fogging of the glasses, water in the mask body, repulsive and uncomfortable due to re-suction of hazy air).

Description

[0001] The present invention relates to a dust-proof mask having an exhaust mouthpiece,

The present invention relates to a dust-proof mask, and more particularly, to a disposable dust mask having an exhaust valve on the front side of the dust-proof mask body and a fixing band on the edge thereof.

In the conventional dustproof mask, as shown in FIG. 1, two fixing bands 2 for wearing a mask are attached to the edge of the mask body 1 which is formed by bending the mask body 1 in conformity with the face portion, And an exhaust valve 3 is attached to the exhaust port 3 so as to escape.

In the dustproof mask having the above structure, the air inside the breathing room escapes more to the mask body part 1 than to the exhaust valve 3 attached to the dustproof mask, And the moisture in the air inside the room was condensed in the mask body, so that the water was stopped and it was very difficult to wear the mask for a long time.

In the course of breathing regardless of the season, when the air passes through the body of the mask, the body is pushed into the body to remove the mask, and then the body is very disproved due to the smell when it is used again. Humid and turbid air remaining in the empty space (4) must be re-introduced every time it breathe, so that the feeling of wearing is very uncomfortable and frustrating, avoiding the wearing of the dust mask.

In order to solve the above-mentioned disadvantages, in the present invention, the Nash makes most of the breath air escape through the exhaust valve without passing through the mask body, so that even when the mask is worn for a long time, I did not want to be frustrated, and I always focused on maintaining a comfortable state.

In order to achieve the above object, according to the present invention, as shown in Figs. 1 and 2, the inner surface of the exhaust valve 3 is tapered (stepped) ), Insert a mouthpiece (5) shaped like a trumpet into the exhaust valve.

After wearing the above dust mask, lightly plug the tip of the mouthpiece connected to the exhaust valve into the lips (place between the lower two lips) and spit on the breathing mouth only, So that the damp air exits only to the exhaust valve (3).

In the above process, the breathing of the breathing room is immediately exited only through the exhaust valve, so that there is no cloudy air between the face part and the mask body 4.

When the user breathes again, the air outside the mask is filtered by the dust-proof mask main body 1 so that only clean air can be sucked in. At this time, the mouthpiece attached to the lips is influenced by the check valve function of the exhaust valve It does not.

By doing so, it is possible to solve all the inconveniences caused by wear of the dust-proof mask (fogging glasses, water condensed on the mask body, unpleasant smell on the body, Regardless of the season, it can be worn comfortably at all times.

Fig. 3 is a view showing the stereo-figure of the mouthpiece in various directions (* the lower part shows a front view)

The following description will be made with reference to the accompanying drawings.

First, as shown in the drawings, a dust mask according to the present invention includes a mask body 1, which is formed by bending a concave portion of the mask to fit the face portion of a conventional dust mask, and a fixing band 2 are connected to each other at two locations and the shape of the basic shape is the same as that of the conventional dust mask having the exhaust valve 3 attached to the center of the body.

Here, before explaining the difference between the conventional dust-proof mask and the dust-proof mask according to the present invention, the structure in which the exhaust valve is attached will be described first.

2, the outer assembly 3-1 is positioned from the outer side with a hole drilled in the center of the body 1, the rubber plate 3-2 for the exhaust valve is located inside the outer assembly 3-1, And the exhaust valve is attached by pressing the inner assembly (3-3) of the exhaust valve past the hole pierced through the hole. The conventional dustproof mask and the dustproof mask according to the present invention have the same structure.

The difference between the dust mask according to the present invention is that the inner surface of the inside of the exhaust valve inner assembly 3-3, which is the inner component of the exhaust valve 3 attached to the dustproof mask, ), And a morning glory mouth piece (5) is sandwiched therebetween.

The shape of the mouthpiece is similar to the shape of a morning glory or a trumpet. It is pierced with a structure in which the lips can be sucked out of the breath.

The shape of the mouthpiece is fitted in the shape of a morning glory in a narrow and flat portion 5-1 in which the lips are contacted and in the engagement jaw 3-4 formed in the inner surface of the inner assembly 3-3 of the exhaust valve 3 (5-2) made of soft elastic material to make movement relatively freely and do not damage the lips or teeth.

The mouthpiece may be directly connected to the inner inner assembly of the exhaust valve (in the form of a body), but in this case the mouthpiece needs a soft material and the inner assembly of the exhaust valve is rigid It would be rather bad because of the material needed.

Also, since the mouthpiece and the exhaust valve are manufactured separately, they can be attached to and detached from each other. In some cases, the mouthpiece may be removed and worn.

The shape of the outer assembly of the exhaust valve should be such that the exhausted air can escape downwards rather than upwards.

The above techniques are summarized as follows.

The dust-proofing mask body 1, which is formed by concavely curving in conformity with the face portion, is provided with two fixing bands 2 which are attached to both sides of the side edge so as to wear a mask. (3), which is an inner component of an exhaust valve (3) attached to a dustproof mask, is attached to an inner circular surface of an exhaust valve inner assembly (3-3) Shaped mouthpiece 5 is sandwiched therebetween and an exhaust valve 3, which is an inner component of the exhaust valve 3 attached to the dustproof mask, The inner assembly 3 - 3 has an inner circular surface formed with a stop jaw 3 - 4 in the form of a stepped jaw, and a morning glory mouth piece 5 is inserted therebetween. The shape of the morning glory And a circular fastening jaw (3-4) formed on the inner surface of the inner assembly (3-3) of the exhaust valve (5) (5-2), and the material should be made of a soft elastic material so that the movement is relatively free and the lip and the tooth portion are not damaged.
