Description

Anti-fog Mask {Anti-Fog Mask}

The present invention relates to an anti-fog mask, and more particularly, a mask for preventing anti-fogging, in which a user wearing a mask effectively discharges exhalation out of the mask when breathing to prevent the mask edge from being separated from the user's face and enables smooth breathing. It is about.

In general, masks are widely used to cover the nose and mouth or to protect against cold weather in order to prevent inhalation of germs and dust. In particular, in recent years, air pollution caused by yellow dust, fine dust, etc. is serious, and more people are often seen wearing masks when going out.

A typical mask has a shape in which earrings are symmetrical with a main body on which a filter for filtering foreign substances from outside air is formed, and both earrings are hung on the wearer's ear to cover the nose and mouth. However, because the degree of protruding nose and mouth is different for each wearer, the main body does not come into close contact with the face, and the main body comes into close contact with the nose and mouth due to one side opening or exhalation or exhalation. Not only is the function degraded, but there is a problem of difficulty in breathing itself.

In addition, when exhalation is discharged to the outside of the mask, the mask area is spaced apart from the user's face around the nose, which is relatively curved, and the exhalation flows out through the gap, and when the eyeglasses are worn in a severe case, there is a problem that the rim of the eyeglass lens occurs .

In order to solve this problem, Korean Utility Model Registration No. 221,064 inserts a snore blocking member made of a soft material into the bag portion and the bag portion formed integrally at the end of the upper portion, and the upper end of the mask body inside the snore blocking member. Anti-fogging mask is known, characterized in that the wire or the shape memory alloy is inserted and fixed to be in close contact with, fixed to. However, this still causes problems such as difficulty in breathing because the exhalation is not discharged to the outside of the mask smoothly, and the wire or shape memory alloy is frequently deformed by external forces such as relatively intense facial movements or face pressing. There is a problem that occurs so that the function of anti-fog deterioration.

Korea Utility Model Registration No. 221,064

The present invention has been made in order to solve the above-described problems, the curved portion is maintained in a state protruding to the front through the combination of the shape of the sheet constituting the anti-fog mask to the front edge of the mask is in close contact with the user's face and the nose and The area where the mouth is located is spaced apart from the user's face to secure a breathing space, and the user's exhalation is smoothly discharged to the outside of the mask to allow for smooth breathing even when the mask is worn. It is to provide an anti-fog mask.

In addition, the present invention is to provide an anti-fog mask to be forced to exhaust the exhalation through the fan unit to the outside of the mask to prevent the anti-fog and more smooth breathing.

Other objects of the present invention will become clearer through the preferred embodiments described below.

Two sheets 10 consisting of an earring hole 11 formed on one side and a curved portion 12 protruding in the opposite direction to the earring hole 12 forming position on the other side are symmetrically coupled around the curved portion, but the curved portion 12 Is formed to protrude to the front side, one of the two sheets 10 of the mask body is provided with a bracket fastening hole 13 in the sheet 10 and the valve engaging projection 21 is formed in the center, the valve The lower bracket 20 in which a plurality of valve support ribs 22 are provided radially so that an exhaust hole is formed between the coupling protrusions 21, and the valve coupling protrusion 21 is inserted into the center. Protrusion fastening hole 31 is formed, the plurality of valve deformed ribs 32 are provided radially so as to be formed to be spaced apart from the valve support ribs 22 gradually from the center to the outer side to form an exhaust hole therebetween. Autumn formation A valve hole 41 to which the valve coupling protrusion 21 is coupled is formed in the upper bracket 30 and the center thereof, and the valve protrusion 42 is spaced apart from the lower bracket 20 on the outer circumferential surface of the valve hole 41. Is provided is coupled between the lower bracket 20 and the bracket 30, consisting of an elastically deformable valve 40, the bracket between the outer portion of the lower bracket 20 and the outer portion of the upper bracket 30 The antifogging mask, characterized in that coupled to the mask body so that the outer peripheral surface of the fastening hole (13) is located.

At this time, the material of the sheet 10 is composed of a polyurethane of 0.2 ~ 0.6mm thickness is preferably bonded by the adhesive so that the curved portion 12 protrudes to the front. The front filter body and the rear filter body may be further provided on the front and rear surfaces of the region where the user's nose and mouth are located.

As described above, since the two sheets of polyurethane material 10 having a predetermined thickness constituting the antifogging mask according to the present invention are combined around the curved portion 12, the edge portion of the mask may be removed even without a shape maintaining means made of metal. The area close to the user's face and the user's nose and mouth are spaced apart from the user's face to secure a breathing space. As shown in FIG. 3A, when the user inhales, the valve 40 is in close contact with the valve support rib 22 to prevent the outside air from flowing into the mask body. In addition, as shown in b of FIG. 3, when the user exhales, the valve 40 is brought into close contact with the valve deformation rib 32 and exhausted to a gap formed on the outer circumferential surface of the valve 40. At this time, in order to prevent the valve 40 from being in close contact with the valve deformable rib 32 regardless of inhalation or exhalation, a ring-shaped valve rib 43 is provided on an opposite side of the surface on which the valve protrusion 42 is formed. ) May be further provided.

Accordingly, in addition to preventing outside air inflow, the mask body adheres to the user's face according to the inhalation and exhalation of the user, thereby minimizing repetition of the breathing by minimizing respiratory resistance and exhalation of the lower bracket 20. ) And smoothly discharged through the exhaust bracket consisting of the upper bracket 30 and the valve 40 has the effect of preventing fog on the glasses when the user wears the glasses.

4A and 4B are front perspective views of the exhaust bracket and the fan unit fastened to the antifogging mask body according to the exemplary embodiment of the present invention, respectively, and FIGS. 5A and 5B respectively illustrate the antifogging agent according to the exemplary embodiment of the present invention. The additional configuration of the present invention will be described below with reference to the fan unit back view and the bottom view of the mask for protection.

In order to protect the exhaust bracket consisting of the lower bracket 20, the upper bracket 30 and the valve 40, a plurality of exhaust ports are formed to remove the bracket cover 50 that is detached to the upper bracket 30 It may further include.

At this time, the structure that couples the bracket cover 50 with the upper bracket 30 may be applied to a variety of coupling means, such as assembling by a hook, as well as a method of inserting and rotating a projection in a plurality of grooves.

In addition, a fan 61 rotating by a motor and a battery and a charging terminal 62 for supplying power to the motor are provided, and the switch 63 and the rotary shaft lower side of the fan 61 for driving the motor are provided. The fan unit is provided with a fan exhaust hole 64, the fan is detachable to the upper bracket 30, the fan unit hole 65 is provided on the surface facing the upper bracket 30 where the fan 61 is located It further comprises a unit (60).

At this time, it can be configured to change the rotational speed of the fan 61 through the operation of the switch 63, the fan 61 has a shape to discharge the air to the outside inside the mask body by the rotation. That is, when the user exhales, it is discharged downward through the fan unit exhaust hole 64 in accordance with the rotation of the fan 61.

In addition, the exhaust bracket, the bracket cover 50, and the fan unit 60 including the lower bracket 20, the upper bracket 30, and the valve 40 are easily combined with and separated from the mask body, thereby providing a mask filter life.
