Abstract

A functional mask of the present invention prevents a fabric from blocking a nostril due to inhalation pressure when breathing through a nose by wearing a mask due to a structure in which left and right nose sides corresponding to a left side and a right side of the nose of a wearer with respect to an inner surface of a fabric body are vertically or obliquely bonded, respectively, thereby increasing a breathing amount and improving a wearing feeling.

Description

Functional Mask {The Balaclava Mask}

The present invention relates to a functional mask, and more particularly, to a functional mask having left and right nose pieces (supports) joined to portions corresponding to the left and right sides of the wearer's nostrils with respect to the inner surface of the distal end of the mask.

Personal protection from environmental pollution caused by rapid urbanization due to the deterioration of the natural atmospheric environment such as yellow dust, which is frequently caused by global climate change, air pollution due to rapid urbanization due to economic development, environmental pollution due to population increase, and dust generated in the artificial working environment, and viruses and bacteria. It is often necessary to wear a mask to protect the health of people.

The conventional disposable mask has a pleated front part in which the entire surface of the filter paper is bent several times, a finish part in which both sides of the filter paper are ultrasonically heat-sealed, welded or sewn together with an earring band, and is formed on the upper part of the filter paper to allow free bending. Possible metal wires are provided, so that the metal wire is bent to fit the contours of the wearer's face with severe curvature, and the folds on the front of the filter paper are spread out to evenly adhere to the wearer's nose and lower chin.

However, such a conventional disposable mask enables the length of the earring band to be adjusted according to the wearer's physical characteristics of the face shape, and there is no separate ear length adjustment means, but a long tie when tying both ends of the earring band. Since the earring band is used in a short or short tie, it is very cumbersome to use because it is necessary to repeat the inconvenient operation such as knotting the earring band or releasing the knot at all times when wearing or releasing it or adjusting the length according to the wearer's body type.

So, in the proposed conventional mask of Utility Model Registration No. 321107, separate finishing members are ultrasonically welded on both sides of the mask, but the earring band is built in the inside of the finishing member so that the earring band is more than a certain level by the bending pressing force of the finishing part. It is made to be pulled by a tensile force, and a groove and a guide handle are formed in the middle part of the finished part, and the length of the earring band is adjusted by drawing out the middle part of the earring band by the groove.

However, since the mask of this structure is made of spandex or neoprene without a nose piece (nose support), it not only has excellent adhesion along the curve of the wearer's face when worn, but also has no lifting phenomenon. There was a problem that the nostrils were blocked by being in close contact with the nostrils, making breathing difficult.

Republic of Korea Utility Model Registration No. 321107 (July 11, 2003)

The object of the present invention is proposed to solve the problems in consideration of the existing problems, and it is possible to increase the breathing volume by preventing the fabric from blocking the nostrils by the inhalation pressure when breathing through the nose while wearing a mask. To provide a functional mask that can be improved.

A functional mask according to an embodiment of the present invention for solving the above technical problem, the left and right distal body parts respectively formed with the left and right earring bands; The left and right nose pieces are respectively joined to the parts corresponding to the left and right sides of the wearer's nostrils with respect to the left and right distal body parts to prevent the fabric from blocking the wearer's nostrils by inhalation pressure when wearing the mask; including; characterized in that

As another embodiment, the left and right nose pieces of the present invention are characterized in that they are respectively bonded to the inner surface of the left and right distal body parts.

As another embodiment, the left and right nose pieces of the present invention are characterized in that they are respectively bonded to the outer surfaces of the left and right distal body parts.

As another embodiment, the left distal body and the right distal body of the present invention are characterized in that a central junction is formed at the vertical end forming the central portion of the mask by contacting each other.

In another embodiment, the left and right nose pieces of the present invention are characterized in that they are made of plastic.

As another embodiment, the left and right nose pieces of the present invention are characterized by a length of 15 to 35 mm, a width of 1.5 to 3 mm, and a thickness of 0.5 to 2 mm.

As another embodiment, the left and right nose pieces of the present invention are characterized in that when they are respectively bonded to the inner surface or the outer surface of the left and right distal body parts, they are respectively bonded vertically from the front of the mask.

As another embodiment, the left and right nose pieces of the present invention are characterized in that when bonded to the inner surface or the outer surface of the left and right distal body parts, respectively, they are bonded at an angle of up to 20° from the front to the left or right of the mask inclined.

Since the functional mask of the present invention has a structure in which the left and right nose pieces are respectively joined to the parts corresponding to the left and right sides of the wearer's nostrils with respect to the inner surface of the fabric body, the fabric is moved to the nostrils by the inhalation pressure when breathing through the nose while wearing the mask. It has the advantage of improving the wearing comfort while increasing the breathing volume by preventing the blockage in advance.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings Figs. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. Accordingly, the shape of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same configuration in each drawing is sometimes illustrated with the same reference numerals. Detailed descriptions of well-known functions and configurations determined to unnecessarily obscure the gist of the present invention will be omitted.

1 to 3, the functional mask (1) of the present invention, the left and right earring band portions (12a, 12b) are formed, respectively, the left and right distal body portions (10a) (10b); a central bonding portion 14 for bonding the vertical ends of the left distal body 10a and the right distal body 10b in contact with each other to form a central portion of the mask 1 by ultrasonic waves; With respect to the inner or outer surfaces of the left and right distal body parts 10a and 10b, respectively, they are bonded to the portions corresponding to the left and right sides of the wearer's nostrils, and the fabric is exposed to the wearer's by inhalation pressure when wearing the mask 1 It includes; left and right nose pieces (20a, 20b) to prevent blocking the nostrils.

At this time, the left and right nose pieces 20a and 20b are made of plastic, and have a length of 15 to 35 mm, a width of 1.5 to 3 mm, and a thickness of 0.5 to 2 mm, and it is preferable that the upper and lower ends of the vertical side are curved. .

In addition, the left and right nose pieces 20a and 20b are vertically bonded in front of the mask 1 when bonded to the inner or outer surfaces of the left and right distal body portions 10a and 10b, respectively, or , are joined at an angle of up to 20° to the left or right from the front of the mask 1 .

That is, the left and right nose pieces (20a, 20b) are vertically erected on the portions corresponding to the left and right sides of the wearer's nostrils as shown in FIG. It is preferable that each is joined to the outer surface.

In addition, the left and right nose pieces (20a, 20b) are the left and right distal body parts (10a) ( 10b) is preferably joined to the inner surface or the outer surface, respectively.

In this way, the functional mask of the present invention has left and right nose pieces (20a) (20b) on the left and right parts corresponding to the left and right sides of the wearer's nose with respect to the inner or outer surfaces of the left and right distal body parts (10a, 10b) Because this structure is vertically or obliquely joined, it is possible to improve the fit while increasing the breathing volume by preventing the fabric from blocking the nostrils by inhalation pressure when breathing through the nose while wearing the mask 1 .

That is, there is a large difference in the amount of respiration (difference in the area in which air enters through the mask) depending on the presence or absence of the left and right nose pieces 20a and 20b in the mask 1 of the present invention.

If the mask is used without the left and right nose pieces as before, the mask fabric blocks the nostrils during inhalation, so the area through which air directly passes through the mask fabric is reduced, making breathing difficult.

That is, assuming that the corresponding area is the same as the area of the nostril, the area through which air can actually pass is as follows.

Assuming that the size of a common nostril is 9mm in long diameter and 7mm in short diameter, the following calculation formula appears.

4.5mm x 3.5mm x 3.14 (circumference) x 2 (number of nostrils) = 98.91mm2

However, when the left and right nose pieces 20a and 20b are added to the mask 1 as in the present invention, an empty space is created between the nose and the pharynx, and air enters through the mask 1 covering the space. As a result, the area through which the actual air passes increases.

That is, in the corresponding area, a trapezoid having an upper side of 25 mm, a lower side of 30 mm, and a height of 20 mm is formed on both sides of the mask 1, and assuming such a corresponding area, the following area is obtained.

(25mm　+ 30mm) x 1/2 x 20mm x 2 = 1100mm2

Here, when the two calculation formulas are checked, there is an area difference of about 11.12 times depending on the presence or absence of the left and right nose pieces 20a and 20b, and there is an effect of increasing the respiration volume by the difference in the area.

On the other hand, the present invention is not limited to the above-described embodiments, but can be implemented with modifications and variations without departing from the gist of the present invention, and the technical idea to which such modifications and variations are applied also falls within the scope of the following claims. have to see
