Description

Dustproof mask

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-proof mask, and more particularly, to a dust-proof mask for preventing wear of a wearer wearing glasses.

The dust-proof mask is mainly used in an environment with many floating dusts. The structure of a general dust-proof mask is shown in FIG.

FIG. 1 shows a structure of a dust-proof mask disclosed in Japanese Patent Application No. 10-1266926, which includes a filter layer for purifying air, a ventilation hole 41 formed at a central portion thereof, a mask body 10 covering the wearer's nose and mouth, (20) provided on both sides of the mask body (10) for wearing on the face and a vent hole (41) of the mask body (10) so that when the wearer breathes out, An exhaust valve 40 composed of the flexible valve flap so as to block the vent hole 41 when the vent hole 41 is opened and the wearer breathes the vent hole 41, 10) to adhere to the nose so as to block the inflow of dust.

Accordingly, when the wearer breathes, the outside air filtered by the dust is introduced into the mask body 10 through the mask body 10, and when the wearer breathes out, the exhaust valve 40 is opened and discharged .

However, when the user wears out the breathing mask, the pressure in the space between the mask body 10 and the face of the wearer increases rapidly, so that the mask body 10 is exhausted from the face and exhausted. In this case, It is very uncomfortable for the wearer wearing glasses to wear protective glasses due to the breath exhausted into the space of the upper part of the body 10, that is, the nose area, which is very inconvenient. There is a problem in that the number of users increases.

In order to solve such a conventional problem, the present invention provides a dustproof mask for preventing the windshield of the spectacles by causing the breath exiting to the upper side of the mask body to be guided to the lower part of the mask through a separate space inside the mask, It has its purpose.

According to an aspect of the present invention,

A mask body;

An upper shape adjuster positioned inside the mask body to allow the mask body to adhere to the nose along the contour according to the nose of the wearer;

The mask body is disposed on the inner side of the mask body so as to be spaced apart from the upper side of the upper shape adjusting unit so that the mask body can be closely attached to the nose along the contour according to the shape of the nose of the wearer, A lower shape adjuster for forming a space between the upper shape adjuster and the upper shape adjuster;

A communicating portion communicating with the space portion and being isolated from the interior of the mask body;

And a first exhaust valve located at a front portion of the mask body at a position of the communicating portion to exhaust air in the space portion.

And a second exhaust valve for exhausting the air inside the mask, wherein a valve case is disposed outside the first exhaust valve and the second exhaust valve, and the valve case is exhausted from the first exhaust valve, The air is guided to the position of the exhaust port where the air of the second exhaust valve is exhausted and exhausted.

According to the present invention constructed as described above, since the breath exhaled through the nose of the mask body is quickly exhausted to the front face of the mask body through the space portion and the communicating portion, the glasses are prevented from being frosted to thereby prevent visual disturbance, Can be prevented.

1 is a view showing the structure of a conventional dust mask.
2 is a view showing the structure of a dust-proof mask according to the present invention.
3 is a cross-sectional structural view of the wearer of the present invention.
4 is a view showing a structure of an exhaust valve and a valve case.

The present invention will be described with reference to the accompanying drawings.

FIG. 2 is a cross-sectional view of a dust-proof mask according to an embodiment of the present invention. FIG. 3 is a cross-sectional view of a wearer of the present invention. The mask body 100 surrounds the wearer's nose and mouth, And may be formed of polyester, polypropylene, nonwoven fabric or the like so that only the fresh air can be introduced into the inside by filtering polluted air or dust.

On both sides of the mask body 100, a fixing strap 110 is provided so that the wearer can wear the mask.

In addition, the mask body 100 is provided with a second exhaust valve 170 at its center so as to smoothly exhaust the exhaust gas due to the wearer's exhalation.

That is, since the pressure increases in the space between the mask body 100 and the wearer's face due to the exhalation, the mask body 100 may be lifted from the face and contaminated air from the outside may be introduced, So that the mask body 100 can be prevented from being lifted.

The structure up to this point is the same as the general structure of the related art, so that the gist of the present invention will be described in detail.

In the present invention, an upper shape adjusting unit 120 is provided so as to protrude from an upper side of the inner side of the mask body 100 (for example, a position corresponding to the upper side of the wearer's nose) The mask body 100 can be brought into close contact with the nose along the contour according to the shape of the nose at the upper portion of the wearer's nose to prevent the contaminated air from flowing into the gap between the nose and the mask body 100.

The length of the upper shape adjuster 120 may be a length that can be bent along the contour of the nose while connecting the cheekbones of the wearer, and may have a length of about 3 to 12 cm.

A lower shape adjusting unit 130 is provided on an inner surface of the mask body 100 at a position spaced apart from the upper shape adjusting unit 120 (for example, a middle position of the wearer's nose) Both end portions of the lower shape adjusting portion 130 are abutted with both end portions of the upper shape adjusting portion 120 so that the space portion 140 is formed between the upper shape adjusting portion 120 and the lower shape adjusting portion 130, .

The upper shape adjuster 120 is made of a soft material such as silicone or rubber and has an inner surface 121 formed on one side of a housing 121 having a cross- And the adjusting piece 122 is inserted in the longitudinal direction so that the mask body 110 is bent along the outline of the nose outwardly from the inner side of the housing 121 to bring the mask body 100 into close contact with the wearer's nose, A sponge 123 is inserted in the longitudinal direction from the inside to the inside of the housing 121 so that the hard adjusting piece 122 does not discomfort the wearer's nose and face.

The lower shape adjuster 130 has the same structure as that of the upper shape adjuster 120. The soft housing 121 is wrapped around the wearer's nose and face by a sponge 123 So that outside air can not easily flow through the gap.

The central portion of the lower shape adjuster 130 is opened and the communicating portion 150 is formed on the inner surface of the mask body 100 downwardly from the opened portion of the lower shape adjuster 130 to interlock with the space portion 140, The upper side is communicated with the space portion 140, the side portion and the lower side are closed, and the shape of the close pocket is set to be I have.

A first exhaust valve 160 is formed in the mask body 100 below the communicating part 150 to connect the communicating part 150 to the outside of the mask body 100, The second exhaust valve 160 exhausts the air inside the mask body 100 to the outside without introducing outside air as in the second exhaust valve 170.

Accordingly, when the user wears the mask body 100 to adjust the upper and lower shape adjusters 120 and 130, the upper and lower shape adjusters 120 and 130 can be used to adjust the contour of the upper and middle parts of the nose, The mask body 100 is brought into close contact with the nose.

Thereafter, when the wearer is exhaled, the pressure increases in the space between the mark body 100 and the wearer's face. Part of the pressure is exhausted through the second exhaust valve 170, and the pressure of the exhalation The shape adjusting unit 130 slightly flickers to generate a gap.

Through this gap, the exhalation flows into the space 140. The exhalation introduced into the space 140 is directly exhausted to the outside through the communicating part 150 and the first exhaust valve 160, Since the pressure is lowered in the part 140, the upper shape adjusting part 120 is kept in a state of being in close contact with the face of the wearer without lifting.

As a result, a part of the expiration is prevented from being exhausted to the upper side of the mask body 100, thereby preventing the glasses from being scuffed.

The valve case 180 is attached to the outer surface of the mask body 100 in which the first exhaust valve 160 and the second exhaust valve 170 are positioned to exhaust more quickly through the first exhaust valve 160. [ As shown in FIG. 4, the valve case 180 has an exhaust port 181 that covers the first exhaust valve 160 and the second exhaust valve 170 and opens downward. An isolation wall 182 for isolating the first exhaust valve 160 and the second exhaust valve 170 is formed.

An exhaust passage 183 is formed by the isolation wall 182 so that the exhaust air exhausted from the first exhaust valve 160 can be exhausted to the exhaust port 181 side.

Therefore, when the high exhaust pressure from the second exhaust valve 170 is discharged through the exhaust port 181, the exhaust air having a comparatively low pressure, which is exhausted through the exhaust path 183, is sucked and sucked out through the exhaust port 181 And exhausted.

As a result, the pressure of the space 140 is rapidly lowered, and the exhalation to the upper side of the mask body 100 is completely prevented.
