Description

Anti-fog mask {ANTI-FOG MASK}

The present invention relates to an anti-fog mask, and more particularly, it can be worn regardless of the face shape of the mask wearer, and also effectively blocks the breath coming out of the mouth or nose when wearing the mask, so that moisture is condensed on the mask body It relates to a mask that can prevent the occurrence of fogging on the lens of the wearer who wears glasses by preventing the leaking of the breath or snoring into the upper part of the mask.

The atmosphere in which people live contains a lot of foreign substances such as fine dust, and these fine dust and yellow dust enter the human respiratory system and cause various diseases, causing fatal adverse effects on people living in modern times.

Here, the fine dust is small and fine dust particles that are invisible to our eyes, and includes numerous air pollutants along with sulfur gas, nitrogen oxides, lead, ozone, carbon monoxide, and the like. It is divided into artificial occurrence and natural occurrence, such as yellow dust from sandstorm dust, volcanic ash, and dust from forest fire. In particular, if the elderly and the weak continuously inhale, there is a problem that the immune function is lowered, leading to death from lung disease.

Masks filter such fine dust so that purified air can be sucked, so it is strongly recommended to wear a mask during outdoor activities.

Masks are also used as the reason for the generation of such fine dust, but the demand for them is significantly increasing in that they are being actively proposed as personal protective measures to prevent the spread of respiratory infectious diseases that are prevalent worldwide.

In order to respond to this demand, mask manufacturers are actively developing technologies to make and distribute masks more easily, and consumers also recognize masks that were worn only in special situations as essentials for life, making life easier and easier. Masks that can be safely applied are required.

The mask may be broadly classified into a cotton mask, a non-woven fabric mask, and the like, depending on the material constituting the mask.

Although a cotton mask has the advantage that it can be reused after washing, it has a disadvantage in that the filtration rate is low. Suitable as a mask.

On the other hand, most of the masks have a shape and structure that is integrated by sewing a hanging string on the inner edge of the outer skin, so there is a problem that breathing is not smooth due to moisture discharged from the nose or mouth in winter when the ambient temperature is low. Due to this, the user who wears the glasses has a problem in that the discharged moisture comes into contact with the glasses, and condensation occurs on the glasses.

In addition, when moisture is condensed on the mask surface due to moisture inside the mask, in the case of a cotton mask, the cotton mask becomes wet and causes discomfort when worn. When exposed to , there was a problem that the filtration rate was significantly lowered.

Therefore, there is a strong demand for the development of a mask technology that can minimize the generation of moisture inside the mask during respiration.

The mask according to the present invention can be worn regardless of the face shape of the mask wearer, and also prevents moisture from condensing in the mask body 10 by effectively blocking the breath coming out of the mouth when wearing the mask, and in particular, the mask It has a structure that can prevent the leaking of breath to the upper part of the eyeglasses and prevent the wearer's lens from getting stuck in the lens.

To this end, the mask according to the present invention may be largely defined as including a main body 10, a pair of earrings 20 and a mouth covering part 30 as shown in FIGS. 1 to 4 .

First, the main body 10 is a portion that covers the wearer's face, and is preferably formed to protrude forwardly with respect to the central sewing line 11 .

When the central portion of the main body 10 is formed to protrude in a curved manner, complementary to this, the space between the main body 10 and the wearer's face can be formed to be more expanded, and thus a person with a protruding mouth can wear the mask without difficulty. can be worn.

In addition, by providing sufficient space between the body 10 and the wearer's face, it is possible to maintain a gap between the body 10 and the mouth covering part 30 to be described later, thereby minimizing the feeling of foreign body when wearing the mask.

The body 10 may be configured by sewing with each other in a state in which a pair of unit members made of a material such as natural or synthetic fiber, nonwoven fabric, etc. are symmetrically formed with respect to the sewing line 11, and if necessary, the sewing line 11 ) is omitted and it is revealed that it can be molded into various shapes, such as by protruding and forming a curved unit member.

Since the left half and the right half of the body 10 can be folded symmetrically with respect to the sewing line 11, a separate fold line is formed on the mask when storing the mask, so that the mask can be easily folded and stored even if the mask is folded. can

An iron core 15 that can be bent to fit the shape of the bridge of the nose may be embedded in the upper edge of the body 10 .

The earring 20 is formed at the left and right ends of the main body 10, and the ear insertion hole 21 into which the wearer's ear is inserted may be penetrated.

The earring 20 is a part that is hung on the ear of the mask wearer, and various selections are possible within the range that can be hung on the ear part. In this embodiment, the earring 20 through which the ear insertion hole 21 is formed is exemplified in a state integrally configured with the body 10 made of the same material as the body 10, and the earring 20 is used as a member such as a rubber ring if necessary. ) can be configured.

The ear insertion hole 21 may be formed through the earring 20 within a range in which an ear can be inserted, such as a circular shape or an oval shape.

The mouth covering part 30 allows moisture to be condensed on the back of the main body 10 to block the breath discharged from the mouth when the mask wearer exhales, or the breath is discharged to the upper part of the main body 10, so that the wearer's glasses are fogged. There is a purpose of preventing the occurrence of snoring, and as shown in FIGS. 2 and 6 , a passage through which only snoring is discharged is formed as a predetermined space between the mask body 10 and the mouth covering part 30, ) and the mouth below the pharynx, a passage through which only the breath is discharged is separately formed, so that it is positioned in a space where the nose and the mouth are completely separated by the mouth covering part 30, thereby satisfying the above object.

To this end, the mouth covering part 30 is formed on the rear surface of the main body 10 to cover the wearer's mouth except for the nose to block the wearing.

In particular, the mouth covering unit 30 in the present invention can be elastically adjusted in response to the position of the mouth that changes depending on the wearer's face shape and face size, etc. It has a structure that can block it.

To this end, the mouth covering part 30 is made of a material that is stretchable so as to be in close contact with the skin across the pharyngeal region of the wearer, and the left and right both ends are fixed to the inner surface of the earring 20, respectively, and the adhesive band 31 and the It may be exemplified as including a mouth covering film 32 extending downward from the adhesion band 31 to cover the main surface of the mouth.

A core material 32, such as a rubber band, may be embedded in the inside of the adhesive band 31, and through this, the adhesive band 31 itself can be in close contact with the curved face, so that the breath is leaked to the top of the adhesive band 31. can be prevented from happening.

In particular, since both the left and right ends of the close contact band 31 are fixed to the earring 20, a structure is provided that allows the fixed end of the close contact band 31 to be in close contact with the wearer's ear point as much as possible.

In this way, the adhesive band 31 itself can contact the wearer's face in a wider area, and a stronger tensile force is applied to the adhesive band 31 in contact with the wearer's face in the direction of the arrow shown in FIG. Since the structure can be, the adhesion band 31 is more strongly in close contact with the wearer's facial skin, so that airtightness can be further improved.

Here, as shown in FIG. 4 , the left and right ends of the adhesive band 31 are preferably attached to within 5 cm of the outermost point 22 on the front side of the ear insert 21 .

When the distance (W) between the end of the adhesion band 31 and the outermost point 22 on the front side of the ear insert 21 exceeds 5 cm, the separation distance between the adhesion band 31 and the ear insert 21 ( As W) increases, the tensile force applied to the contact band 31 wrapped around the wearer's face is lowered, and thus, the adhesive band 31 cannot be in strong contact with the wearer's face.

In addition, since the adhesive band 31 itself can be stretched or compressed, it can be elastically applied to different face sizes and face shapes, etc. have.

In addition, both left and right ends of the adhesive band 31 are attached to the earring 20 , and the mouth cover 32 is not fixed to the earring 20 and the main body 10 , but is the lower edge of the adhesive band 31 . Since it is fixed on the close contact band 31 along the , the angular movement of the mouth covering part 30 itself can be made freely within a predetermined angular range.

In this way, according to the height of the mouth, the relative position of the mouth covering part 30 can be adjusted as in the direction of the arrow shown in FIG. can be placed around it.

The mouth covering membrane 32 is a member in the form of a membrane extending to the lower portion of the adhesion band 31 , and covers the periphery of the wearer's mouth to prevent the mouthpiece from leaking toward the rear surface of the body 10 .

At this time, it is preferable that the upper end of the mouth cover 32 is fixed to the adhesion band 31 , and both left and right side ends and the lower end of the mouth cover 32 are formed in the form of free ends.

In this case, the pressure of the breath is appropriately dispersed and discharged to the left, right, and lower ends of the mouth covering membrane 32 , thereby suppressing the moisture condensation phenomenon occurring in the mouth covering membrane 32 itself.

If the close-fitting band 31 or the mouth cover 32 closes all around the mouth as part of preventing the leakage of breath, the breath is excessively concentrated in the mouth cover 32, and the moisture in the mouth cover 32 is condensed. A problem of wet wetting occurs.

To prevent this, when a certain amount of ventilation is formed in the mouth covering film 32 , breath is discharged through the ventilation hole to the rear surface of the main body 10 , and there is a risk that moisture may be condensed on the main body 10 .

Accordingly, the mask according to the present invention seals the upper part of the mouth periphery through the adhesion band 31, and configures the mouth cover film 32 below the adhesion band 31 in the form of a curtain film to cover the mouth area. This prevents direct transmission to the main body 10 and at the same time distributes the pressure of the breath and discharges it to the left, right, and lower sides of the mouth covering membrane 32, so that the moisture caused by inhalation into the mouth covering membrane 32 itself. Condensation can be prevented. In addition, since it does not directly press the mouth, excessive blocking of the mouth can be prevented, thereby improving the wearing comfort and guaranteeing the degree of freedom of the mouth, thereby providing the advantage of enabling clearer speech transmission even while wearing a mask.

The mouth covering part 30 may be configured to be detachable from the body using means such as Velcro, if necessary.

The mask according to the present invention may further include a nose covering portion 40 formed on the upper end of the rear surface of the main body 10 to cover the wearer's nose to block snoring.

The nose covering part 40 is in the form of a curtain film configured to surround the periphery of the nostrils from the bridge of the nose when the mask is worn, and has the same configuration as the above-described mouth covering film 32 .

That is, the nose covering part 40 prevents snoring from being transmitted directly to the main body 10 by covering the periphery of the nose, and at the same time, by dispersing the pressure of the snoring, the left, right and By discharging to the lower side, it is possible to prevent condensation of moisture due to snoring in the nose covering part 40 itself. In addition, since it does not press the periphery of the nostrils, the nose covering unit 40 itself does not interfere with breathing through the nose, and snoring generated during respiration is between the nose covering unit 40 and the main body 10 (Fig. 9). It is guided in the direction of the arrow shown in ) and is provided with a structure that can prevent the snoring from flowing out to the upper part of the main body 10 .

On the other hand, in the mask according to the present invention, the main body 10 is divided into a front member 12 and a rear member 13 as shown in FIGS. 10 to 11, and the front member 12 and the rear member ( 13) is configured so that a separate filter member 14 can be embedded therebetween.

The upper edges of the front member 12 and the rear member 13 are in contact with each other to form a closed upper edge of the main body 10, and on the contrary, the lower ends of the front member 12 and the rear member 13 are in the form of free ends. The lower edge of the main body 10 becomes an open shape. The filter member 14 can be configured to be detachable toward the lower end opened in this way.

Since the body 10 itself is curved toward the front, when the filter member 14 is interposed between the front member 12 and the rear member 13 configured in this way, the filter member 14 is formed with the front member 12 and It is tightly fitted between the rear members 13 so as not to be separated by its own weight.

The filter member 14 may preferably use a non-woven fabric filter, and since such a filter is vulnerable to moisture, it is interposed between the front member 12 and the rear member 13 to minimize exposure to moisture. can do it

In addition, since it is possible to separately wash the mask except for the filter member 14 that is vulnerable to moisture, the mask can be used more cleanly. In this case, the filter member 14 may be replaced with a new product depending on the amount used.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms recited in the above detailed description.
