Description

Transparent mask without earring strap

The present invention relates to a transparent mask, and more particularly, to a transparent mask in which the earring string is omitted, which can be worn for a long time without ear pain because there is no need for an earring string because the adhesion to the face is maintained by its own elastic force .

The mask that covers the user's mouth and nose prevents external dust or germs from penetrating into the body through the respiratory tract, and also blocks droplets from being spit out when the user coughs or sneezes. Various types have been developed.

The mask is composed of a main body that covers the mouth and nose, and a hook that is fixed to both ends on the left and right sides of the main body and is worn over the ears. The body, usually, has a structure in which a filter sheet is mounted on a fabric of a woven or non-woven material, and the hanging string is made of an elastic material that can be stretched in length.

However, in the conventional mask, the hanger may cause inconvenience to the use of the mask. As mentioned above, since the hanging strap has elasticity, when time passes while the hanging strap is stretched and worn on the ear, the back of the ear is pressed and pain is felt, leaving traces of the hanging strap on both cheeks in many cases. Accordingly, a hanging strap that can be adjusted in length has been developed, but adjusting the length itself is cumbersome and cumbersome, so it is not used well in practice.

On the other hand, recently, as a special mask, a so-called transparent mask in which the body itself is made of a transparent material is also used. A transparent mask is a transparent film applied instead of a fabric, and the shape of the mouth can be seen from the outside, enabling smoother communication.

As a background technology related to a transparent mask, Korean Patent Registration No. 10-1681100 (film-type transparent mask) has been disclosed. The disclosed transparent mask is a film-type transparent mask comprising a mask body that is in close contact with a part or the entire face of a user, a filter part formed on the lower surface of the mask body to purify the inhaled air, and a fixing part for fixing the mask to the face In the filter unit, one or more vents are formed repeatedly at predetermined intervals in the first film; a second film in which one or more vents are repeatedly formed at predetermined intervals; and a filter layer formed between the first film and the second film, wherein the first vents of the first film and the second vents of the second film are interlaced with each other, and the filter layer is a nonwoven filter or a nanoweb filter and an airtight part made of hydrogel, adhesive, polyethylene foam, acrylic foam or rubber material that can be closely adhered to the user's face is formed on the edge of the film-type transparent mask, and a plurality of tubes on the first film and the second film are formed. Flow paths of various patterns are formed between the pores to maximize the filtration path of the inhaled air, with a length longer than the linear distance between neighboring vent holes, and the inner surface of the flow paths of various patterns contains external harmful substances. It has a structure in which an adhesive or an adsorbent for adsorbing pollutants is applied while air passes through the flow path.

1 is a perspective view of a transparent mask 10 in which an earring string is omitted according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view for explaining the structure of the filter unit shown in FIG. 3 is a cross-sectional view taken along line A-A of FIG. 1 .

As shown, the transparent mask 10 according to the present embodiment includes a transparent cover 20 , an edge sealing member 30 , a filter unit 40 , and an auxiliary string 50 .

The light-transmitting cover 20 is molded and manufactured with a light-transmitting film, and has an elastic deflection to be retracted in the direction of the arrow b. That is, in a state in which no external force is applied, it is completely curled inward and rolled up, and unfolds when the user opens it by hand. When the user releases his/her hand, it shrinks again to dry.

The transparent cover 20, in an unfolded state, can cover the user's face (like a general mask), that is, the mouth and nose, and both ends extend to the back of the jawbone. Therefore, when the light-transmitting cover 20 is unfolded and put in close contact with the user's face and then released, both ends are retracted in the direction of the arrow b by the elastic restoring force of the light-transmissive cover 20, and the mounted state on the face is maintained.

In addition, the edge of the light-transmitting cover 20 is closed with a resilient closing part 24 . The elastic closing portion 24 is a portion formed by rolling the outer portion of the light-transmitting cover 20 inward, and allows the rim portion of the light-transmitting cover 20 and the face to be in close contact more effectively. As long as it can provide such a function, the shape of the elastic closing portion 24 can be changed as much as possible.

In addition, as shown in FIG. 3 , a ventilation hole 21 is formed in the transparent cover 20 . The ventilation hole 21 is a through hole formed at the point where the filter unit 40 is to be mounted, and allows air to pass through when the user breathes.

The filter unit 40 is installed on the outer side of the transparent cover 20 and filters air while passing through it, and includes a filter holder 41, an inner screen 42a, a filter member 43, and a filter case 44. , an outer screen (42c), and a sealing cap (46).

The inner screen 42a is a mesh-shaped member mounted on the ventilation hole 21 , and supports the filter member 43 . Of course, the inner screen (42a) also serves as the bottom surface of the filter holder (41).

The filter member 43 passes air when the user's inhalation occurs, and serves to filter germs or fine dust in the air. Such a filter member 43 can be made of a cloth for a general KF94 or KF80 mask. The filter member 43 is fitted in the receiving space 41e of the cylinder 41b.

The filter case 44 has a cylindrical shape and has a female screw portion 44a and a screen support groove 44c on an inner circumferential surface. The female threaded portion 44a is a portion screwed with the male threaded portion 41c of the cylinder 41b. In addition, the screen support groove 44c accommodates the outer screen 42c. The outer screen 42c takes the shape of a disk and is supported by being inserted into the screen support groove 44c, and prevents the filter member 43 from being separated.

The filter case 44 is detachable from the filter holder 41 for replacement of the filter member 43 . In addition, a cap fixing screw portion 44e is further formed on the outer peripheral surface of the filter case 44 . The cap fixing screw portion 44e is a male screw portion to which the sealing cap 46 is coupled.

The sealing cap 46 protects the outer screen 42c and the filter member 43 by being screwed to the cap fixing screw portion 44e. When using the transparent mask 10, the sealing cap 46 must be removed of course.

On the other hand, the edge sealing member 30, coupled to the edge portion of the light-transmitting cover serves to block the gap between the light-transmitting cover and the skin of the face. That is, it is to block the inflow of dust, etc. into the gap between the elastic closing part 24 and the skin as much as possible. The edge sealing member 30 is a fabric for a KF94 or KF80 mask cut in a strip shape and then folded in half in the width direction, and surrounds the edge of the light-transmitting cover 20 . The fixing of the edge sealing member 30 to the transparent cover 20 may be an adhesive fixing method using an adhesive.

The auxiliary string 50 includes a string body 51 , a hook 53 , and a length adjustment member 55 . The hook 53 is a member connected to both ends of the string body 51 and is coupled to the hook hole 11 formed in the light-transmitting cover 20 . In addition, the string body 51 is a member caught behind the user's neck, as shown in FIG. The length of the string body 51 can be adjusted through the length adjustment member 55, and when the string body 51 is shortened through the length adjustment member 55, it spans the back of the head and adheres the transparent mask to the face more strongly. can do it Since this auxiliary string 50 is a general one, further description will be omitted. In addition, the auxiliary string 50 may not be used.

Hereinafter, the same reference numerals as the above reference numerals refer to the same members having the same function.

As shown, the transparent mask 10 according to the modified example has a rectangular sound passage 26 in the center of the transparent cover 20 . The voice passage 26 is a hole through which the voice passes when the user wearing the transparent mask 10 speaks. By forming the voice passage 26, speech sounds are clearly and clearly heard.

In addition, a blocking sheet 29 is installed in front of the voice passage 26 . The blocking sheet 29 is a rectangular plate-shaped member that covers the voice passage 26 and prevents the user's droplets from diverge forward. The width of the blocking sheet 29 is wider than the width of the voice passage 26 . And the four corners of the blocking sheet 29 are provided with mounting holes (29a). The mounting hole 29a is a hole through which the support protrusion 28 is fitted. The interval between the blocking sheet 29 and the light-transmitting cover 20 may be about 5 mm.

The support protrusions 28 are support means for maintaining the blocking sheet 29 in front of the transparent cover 20 and are located outside the four corners of the voice passage 26 . The support protrusion 28 is composed of an extended portion 28a protruding forward from the light-transmitting cover 20 and an elastic split 28c on both sides.

The elastic split 28c is a portion divided by the gap 28e and is elastically deformable. In other words, when passing through the mounting hole (29a), it is retracted, and after passing through, it is opened again and elastically restored. The blocking sheet 29 is detachable with respect to the support protrusion 28 .

5 is a view showing another modified example of the transparent mask 10 in which the earring string is omitted according to an embodiment of the present invention, and FIG. 6 is a view showing an example of mounting the transparent mask shown in FIG. 5 .

The light-transmitting cover 20 is composed of a lower cover part 23 that covers the lower canal of the face, and an upper cover part 22 that covers the upper part of the lower canal. The lower canal is approximately the area from the bridge of the nose to the chin, and the upper part of the lower canal is the part including the eyes and forehead. The lower cover part 23 and the upper cover part 22 form one body.

In particular, the left and right ends of the upper cover part 22 extend backward (in the occipital direction when worn) to elastically press the user's side head, that is, the side head. Since the upper cover part 22 elastically presses the temporal part, the wearing state of the transparent mask 10 is more stably maintained.

7 is a partial cross-sectional view showing a state in which the adsorption unit 61 is applied to the transparent mask 10 in which the earring string is omitted according to an embodiment of the present invention. The adsorption unit 61 to be described later is applicable to all types of the transparent mask 10 described above.

Referring to the drawings, it can be seen that the sealing chamber 25 is formed on the edge of the transparent cover 20 . The sealing chamber 25, after extending along the edge of the light-transmitting cover 20, both ends meet, that is, form a closed curve, and also serves as a function of the elastic closing portion (24 in FIG. 3) described above. In addition, the sealed chamber 25 provides a negative pressure space (25a).

The adsorption part 61 communicates with the negative pressure space part 25a of the sealed chamber 25 and extends inward (in the direction toward the face), the connecting tube 61c, and the adsorption nozzle coupled to the connecting tube 61c ( 61a). The number of applications of the adsorption unit 61 may vary depending on the embodiment, for example, about 10 may be applied.

The suction nozzle (61a) is a funnel-shaped member made of soft silicone, in close contact with the user's skin in a state in which the sealing chamber 25 is pressed and contracted, and is formed in the negative pressure space portion (25a) when the sealing chamber is elastically restored. It is absorbed by the skin under the action of negative pressure. By applying the adsorption unit 61 in this way, the mounting state of the transparent mask 10 is more stably maintained.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
