Description

Dust mask

The present invention relates to a dust mask, and more particularly, to a dust mask for preventing fogging in glasses of protective eyewear wearers.

The dust mask is mainly used under a lot of suspended dust, and the structure of a general dust mask is shown in FIG.

1 is a structure of a dust mask disclosed in Korean Patent No. 10-1266926, which is provided with a filter layer for purifying air, and a vent hole 41 is formed in the center to be vented and a mask body 10 covering the wearer's nose and mouth. And, it is provided in communication with the hanger 20 provided on both sides of the mask body 10, the vent hole 41 of the mask body 10 to be worn on the face when the wearer exhales An exhaust valve 40 made of the flexible valve flap and a mask body along the contour to fit the nose shape of the wearer so as to open the vent 41 and block the vent 41 when the wearer breathes. 10) is made of a shape adjusting piece 30 to block the inflow of dust to be in close contact with the nose.

Therefore, when the wearer inhales, the outside air in which dust is filtered through the mask body 10 is introduced into the mask body 10, and when the wearer exhales, the exhaust valve 40 is opened and discharged to the outside. Done.

However, since the pressure of the conventional dust mask rapidly increases in the space between the mask body 10 and the wearer's face when the wearer exhales, the mask body 10 is lifted from the face and exhausted. Steaming occurs in the glasses of the wearer who wears the protective glasses by breathing the upper part of the main body 10, that is, the space of the nose area, and is very uncomfortable. This greatly increases the problem.

The present invention is to solve this conventional problem, to provide a dust mask to prevent the fog on the spectacle by quickly exhausting the air exhausted to the upper side of the mask body to the lower portion of the mask through a separate space inside the mask. Its purpose is to.

Dust mask of the present invention for achieving the above object,

Mask body;

An upper shape adjusting part positioned inside the mask main body to allow the mask main body to be in close contact with the nose along the contour according to the wearer's nose shape;

Located in the mask body spaced apart from the lower side of the upper shape adjusting portion to allow the mask body to be in close contact with the nose along the contour to fit the shape of the nose of the wearer, both ends thereof are formed to contact both ends of the upper shape adjusting portion. A lower shape adjusting part which forms a space part between the upper shape adjusting part and the upper shape adjusting part;

2 is a view showing a structure of a dust mask according to the present invention.

Figure 3 is a cross-sectional structural view in a wearing state of the present invention.

Figure 4 shows the structure of the exhaust valve and the valve case.

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

Figure 2 is a view showing the structure of the anti-vibration mask according to the present invention, Figure 3 is a cross-sectional structural view in a wearing state of the present invention, the mask body 100 is wrapped inside the wearer's nose and mouth to facilitate breathing The space may be formed in a three-dimensional shape, and may be formed of polyester, polypropylene, nonwoven fabric, and the like to filter contaminated air or dust and introduce only fresh air therein.

Both sides of the mask body 100 is provided with a fixing strap 110 is configured to allow the wearer to wear a mask.

In addition, the mask body 100 has a second exhaust valve 170 is formed in the center portion so as to smoothly discharge the exhaust gas due to the exhalation of the wearer to the outside.

That is, the pressure is increased in the space between the mask body 100 and the wearer's face by exhalation, so that the polluted air from outside may be introduced as the mask body 100 is lifted from the face. It is possible to prevent the mask body 100 from being lifted up by quickly discharging the exhalation by the outside.

Since the structure so far is the same as the conventional general structure, the gist of the present invention will be described in detail.

In the present invention, the upper shape adjusting part 120 is provided on the inner side of the mask body 100 (for example, a position corresponding to the upper side of the wearer's nose), and the upper shape adjusting part 120 is provided. The mask body 100 may be in close contact with the nose along the contour to fit the nose shape in the upper portion of the wearer's nose to prevent the air contaminated from the outside to enter the gap between the nose and the mask body 100.

The length of the upper shape adjusting unit 120 may have 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.

The lower shape adjusting part 130 protrudes on the inner side of the mask body 100 at a position spaced below the upper shape adjusting part 120 (for example, the position of the middle part of the wearer's nose). Both ends of the lower shape adjusting unit 130 are in contact with both ends of the upper shape adjusting unit 120, respectively, and the space 140 between the upper shape adjusting unit 120 and the lower shape adjusting unit 130. Is formed.

The upper shape adjusting part 120 is made of a soft material such as silicone or rubber, and has an inner surface of the mask body 100 on one side of the housing 121 having a cross-section '┗┛' or 'U' shape. The fixing piece 122 is inserted in the longitudinal direction to be attached to and fixed to the inside of the housing 121 to bend along the contour of the nose to closely contact the mask body 100 with the wearer's nose and face. Inside the housing 121, the sponge 123 is inserted in the longitudinal direction so that the hard adjusting piece 122 does not cause inconvenience to the wearer's nose and face.

The lower shape adjusting unit 130 also has the same structure as the upper shape adjusting unit 120, so that a soft housing 121 is softly wrapped around the nose and face by the sponge 123 on the wearer's nose and face. The outside air does not flow easily through the gap.

On the other hand, while the center portion of the lower shape adjustment unit 130 is open, the communication portion 150 is formed on the inner surface of the mask body 100 in cooperation with the space portion 140 from the open portion to the lower side, the mask It is padded on the inner surface of the mask body 100 with the same material or moisture-proof cloth as the main body 100, the upper side is in communication with the space portion 140, the side and the lower side is in a blocked state similar to the pocket shape. Have.

In addition, a first exhaust valve 160 is formed in the mask body 100 at a lower portion of the communication unit 150 to connect the communication unit 150 and the outside of the mask body 100. Like the second exhaust valve 170, the internal air of the mask body 100 is exhausted to the outside without inflow of external air.

Therefore, when the wearer adjusts the upper and lower

shape adjusting parts

120 and 130 by wearing the mask body 100, the upper and lower

shape adjusting parts

120 and 130 may contour the upper and middle portions of the nose as shown in FIG. 3. Accordingly, the mask body 100 is brought into close contact with the nose.

When the wearer exhales afterwards, pressure increases in the space between the Marks main body 100 and the wearer's face, and some of the exhausts are exhausted through the second exhaust valve 170, and due to the exhalation pressure that is not exhausted. The lower shape adjusting part 130 is slightly excited to generate a gap.

Exhalation is introduced into the space 140 through such a gap, and the exhaled introduced into the space 140 is directly exhausted to the outside through the communication unit 150 and the first exhaust valve 160, and the space is exhausted. Since the pressure is lowered in the unit 140, the upper shape adjusting unit 120 does not lift and maintains a state in close contact with the face of the wearer.

As a result, part of the exhalation is prevented from being exhausted to the upper side of the mask body 100, so that no fogging occurs in the glasses.

On the other hand, the valve case 180 on the outer surface of the mask body 100, the first exhaust valve 160 and the second exhaust valve 170 is located in order to exhaust the expiration more quickly through the first exhaust valve 160 As shown in FIG. 4, the valve case 180 has an exhaust port 181 having a lower side open while covering the first exhaust valve 160 and the second exhaust valve 170, and toward the inside thereof. The isolation wall 182 for isolating the first exhaust valve 160 and the second exhaust valve 170 is formed.

The exhaust path 183 is formed to allow the exhalation exhausted from the first exhaust valve 160 to be exhausted toward the exhaust port 181 by the separating wall 182.

Accordingly, when the pressure exhausted from the second exhaust valve 170 is discharged through the high exhalation exhaust port 181, the exhalation having a relatively low pressure exhausted through the exhaust path 183 may be sucked and quickly flowed through the exhaust port 181. Exhausted.

As a result, the pressure of the space 140 is rapidly lowered, thereby preventing the exhalation exhausted to the upper side of the mask body 100 to be completely prevented, thereby making the antifogging effect very excellent.
