The present disclosure relates to a transparent mask equipped with an oxygen supply means and, more particularly, to a transparent mask equipped with an oxygen supply means capable of receiving oxygen by connecting a transparent member and an oxygen cylinder as well as allowing a mask wearer's face to be checked through a transparent member.
In general, a mask is used to block pathogens such as viruses and the like from being transmitted through the respiratory tract or to block harmful dust or fine dust from entering the human body through the respiratory tract. Regarding such masks, there is a general type in which a mask body made of woven fabric or non-woven fabric and a filter body are configured in a dual structure, and there is a high-functioning type in which an air purifying means and a discharge means are installed in the mask body.
On the other hand, the general type of mask has the advantage of being inexpensive, but there are disadvantages in that when a wearer inhales and exhales, air needs to pass through both the mask body and the filter body, so it is difficult to breathe because the air does not flow smoothly, and moisture is easily formed on the inside of the mask.
The high-functioning type mask has advantages of not causing breathing difficulty and not allowing moisture to be easily formed because the air is circulated smoothly because suction and discharge are separate due to the air purification means and the discharge means but has the disadvantage of being expensive.
However, since the mask covers the mask wearer's face (nose part and mouth part), there is a problem in that the expression of the mask wearer's face may not be seen, causing a sense of caution or rejection rather than a sense of familiarity.
In addition, in the case of deaf people who may not hear sounds due to hearing impairment, there is a problem in that communication may not be accomplished because the shape of the mouth may not be observed.
In order to solve the above problems, film-type transparent mask has been recently registered as Korean Patent No. 10-1681100. This related art is a film type transparent mask, which includes a mask body that is in close contact with all of or a part of the user's face, a filter part provided on a lower surface of the mask body to purify the sucked air, and a fixing part configured to fix the mask to the face, wherein the filter part includes a first film in which one or more vent holes are repeatedly provided at predetermined intervals, a second film in which one or more vent holes are repeatedly provided at predetermined intervals, and a filter layer provided between the first film and the second film, wherein The first vent holes of the first film and the second vent holes of the second film are disposed to be staggered with each other, and the filter layer is a nonwoven fabric filter or a nanoweb filter. In addition, an airtight part made of hydrogel, adhesive, polyethylene foam, acrylic foam, or rubber material that may be brought into close contact with the user's face is provided on the edge of the film type transparent mask, flow paths of various patterns are provided between a plurality of vent holes in the first film and the second film so as to maximize filtration paths of the sucked air by having a length longer than a linear distance between adjacent vent holes, and an inner surface of the flow path of the various patterns is configured to have adhesive or adsorbent for adsorbing contaminants applied thereto during passing of the air containing external harmful substances through the flow path.
In the related art above, the mask body is composed of a transparent plastic film, and thus it is possible to solve the problems of conventional art, but there is a problem that it is difficult to use in an underground space and the inside of a large water tank, where a breathing environment is poor due to ventilation difficulty, or a tank for storing liquid.
In addition, when a fire occurs, there is a problem that breathing of the mask wearer becomes difficult because toxic gases may not be filtered.
The foregoing is intended merely to aid in the understanding of the background of the present disclosure and is not intended to mean that the present disclosure falls within the purview of the related art that is already known to those skilled in the art.

Hereinafter, a transparent mask having an oxygen supply means according to an example of the present disclosure will be described with reference to the drawings.
The transparent mask equipped with an oxygen supply means according to an example of the present disclosure may include a transparent member 110, a coupling member 110′, an air inflow port 120, an air discharge port 120′, and an air outlet means 130.
The transparent member 110 is worn on the face to cover the nose and mouth and may be provided with a transparent material. The material of the transparent member 110 may be polyethylene (PE) or the like. The transparent member 110 may be manufactured in a shape convenient to wear taking the nose, mouth, face, and the like into consideration. The transparent member 110 may be bent in response to the size or shape of the wearer's face when worn but may need to stay to an extent not to wobble due to exhalation or inhalation. Silicone, rubber, and the like may be deformed and brought into close contact with the wearer's face to prevent air from infiltrating in or leaking out.
The coupling member 110′ configured to enable a periphery of the transparent member 110, that is, silicon 111, rubber, and the like to be brought in close contact with the face and may be a band or earpiece connected to opposite sides of the left and right of the transparent member 110 and the like.
The air inflow port 120 is a hole through which air is introduced into the transparent member 110 when the mask wearer breathes in and may be provided passing through at one side of the transparent member 110. One side on which the air inflow port 120 is installed may be an upper side, a lower side, a left side, a right side, or the like of the transparent member 110.
The air discharge port 120′ is a hole through which air is discharged to the outside of the transparent member 110 when the mask wearer exhales and may be provided passing through at an opposite side of the transparent member 110. The opposite side corresponds to a side and refers to a part other than the one side. That is, the opposite side may be a position opposite to the one side or adjacent to the one side.
The one side and the opposite side of the transparent member 110 may be positioned so that the mask wearer's mouth shape may be seen so as to allow the hearing impaired to identify the wearer's mouth shape, that is, the speaking shape.
With reference to
The air discharge guide member 131 is a cylindrical member and may be attached to the outer surface of the transparent member 110 by attachment, fusion, and the like or may be provided integrally with the transparent member 110. A screw may be provided, or a latching portion may be provided, on an outer circumferential surface of the air discharge guide member 131. The inner circumferential surface of the air discharge guide member 131 may be provided with a radially shaped discharge movement guide protrusion 131′ thereon or may be provided without the discharge movement guide protrusion 131′ thereon. A hole may be provided by passing through the inside of the air discharge guide member 131, that is, a surface brought in contact with the transparent member 110, entirely, or by passing through only a portion corresponding to the air discharge port 120′.
The discharge flap 132 opens and closes the air discharge port 120′ and may be provided with a soft synthetic resin material. In a state in which only one side is attached, the discharge flap 132 may be bent during exhalation so that the air discharge port 120′ is opened and may block the air discharge port 120′ by returning back during inhalation. In addition, in a completely separated state, the discharge flap is moved during inhalation and may close the air discharge hole, thereby blocking the inflow of air, and is moved during exhalation and may open the air discharge hole, thereby discharging the air. The discharge movement guide protrusion 131′ may facilitate movement of the discharge flap 132 by minimizing frictional force. The discharge flap 132 may be provided in a sawtooth shape in which a portion corresponding to the discharge movement guide protrusion 131′ is cut off. That is, the discharge flap 132 may be provided by being cut off to allow to an extent only a portion of the discharge movement guide protrusion 131′ to be inserted therein during discharge. Such a sawtooth shape may allow the discharge flap 132 to move in a stable state without being rotated, thereby perfectly performing opening and closing of the air discharge port 120′.
An air discharge fastening member 133 may be fastened and fixed to an air discharge guide member 131 by a screw or a fitting method, thereby preventing the discharge flap 132 from being separated.

The inflow flap 142 may be provided with a soft synthetic resin and may open and close an inflow through hole 143′ of an installation guide member 143 to be described later while moving along the inflow movement guide protrusion 141′ of an outer side. In addition, the inflow flap 142 having one side attached to the installation guide member 143 may introduce air by being bent to be spaced apart from the inflow through hole 143′ during inhalation and may close the inflow through hole 143′ by being returned during exhalation. In addition, in an unattached state, the inflow flap 142 is moved during inhalation and may open the inflow through hole 143′ and is moved and may close the inflow through hole 143′ during exhalation. The inflow flap 142 may be provided in a sawtooth shape in which a portion in which the inflow movement guide protrusion 141′ of an outer side is located is cut off. That is, the inflow flap 142 may be provided with a cut off portion into which a portion of the inflow movement guide protrusion 141′ of an outer side is inserted. Such a sawtooth shape may allow the inflow flap 142 to move in a stable state without being rotated, thereby allowing opening and closing of the inflow through hole 143′ to be perfectly performed.
The installation guide member 143 is a cylindrical shape, an outer side and an inner side are open, an intermediate membrane having the inflow through hole 143′ in the center is provided, and a first space and a second space may be provided on the inner side and the outer side, respectively.

The second inflow flap 182 is made of a soft synthetic resin and may open and close a second inflow through hole 183′ of a second installation guide member 183 while moving along the second inflow movement guide protrusion 181′ of the outer side. In addition, attached to one side of the second installation guide member 183 to be described later, the second inflow flap 182 may introduce air by being bent to be spaced apart from the second inflow through hole 183′ during inhalation and close the second inflow through hole 183′ by being returned during exhalation. When not attached, the second inflow flap 182 is moved along the second inflow inner protrusion 181′ of the outer side during inhalation and may open the second inflow through hole 183′ and is moved along the second inflow inner protrusion 181′ during exhalation and may close the second inflow through hole 183′. The second inflow flap 182 may be provided in a sawtooth shape in which a portion in which the second inflow inner protrusion 181′ of the outer side is located is cut off. Such a sawtooth shape may allow the second inflow flap 182 to move in a stable state without being rotated, thereby perfectly performing opening and closing of the second inflow through hole 183′.
The second installation guide member 183 is a cylindrical shape, an outer side and an inner side are open, an intermediate membrane having the second inflow through hole 183′ in the center is provided, and a third space and a fourth space may be provided on the inner side and the outer side, respectively. The second installation guide member 183 may be coupled to the connection port 181 by having a screw or a latching portion provided on the inner circumferential surface of an inner side. The second installation guide member 183 may have a screw or a latching portion provided on the outer circumferential surface.

The control valve 194 may be mounted to be able to rotate to the coupling pipe 172 while compressing the spring 193. The control valve 194 rotates around the coupling pipe 172 and may control pressing force of the opening/closing ball 192 with an inner spiral-shaped control surface.
A fixing ring 195 may be mounted on the coupling pipe 172, whereby the control valve 194 may be prevented from being separated, and a control surface of the control valve 194 and the opening/closing ball 192 are to be located on the same surface.
A pair of rotation control members 196 configured to control a rotation angle of the control valve 194 may be provided in the coupling member 171.
In addition, the transparent mask may be provided with a floating body installed on the second branch pipe 152. The floating body floats on water and may be Styrofoam, a tube, or the like. The floating body is provided with the second air inflow means 180 exposed into the air over the floating body, so that fresh air above the water may be introduced thereinto. The floating body may allow an end part of the second branch pipe 152 to float on the water, thereby allowing a person wearing the transparent mask to dive into a river, sea, water tank, or the like. In this case, the oxygen cylinder may be installed on the body or waist of the wearer.
In addition, the transparent mask may be provided with a weight installed on the second branch pipe 152. Due to a gravitational action of the weight, the second air inflow 180 may descend outside a window of a building, thereby allowing fresh air from the outside to be introduced into the transparent mask in case of a fire.
In a normal case, that is, the case without the floating body or weight, the present embodiment may be easily used by patients, the elderly, and the like who require a lot of oxygen.
The following describes the process of using one embodiment of the present disclosure.
First, the transparent mask 100 is brought into close contact with a face of a mask wearer. In this case, the transparent mask 100 may cover the nose and mouth of the mask wearer, and the silicone 111 attached to the inner circumference of the transparent member 110 may be brought into close contact with the face.
While the transparent mask 100 is brought into close contact with the mask wearer's face, the transparent mask 100 may be worn by allowing the coupling member 110′ to be positioned on a mask wearer's head or to be hung on the mask wearer's ears. At this time, the silicone 111 and the like attached to the inner circumference of the transparent member 110 by the coupling member 110′ is deformed and brought into close contact with the mask wearer's face, thereby preventing air from infiltrating in or leaking out.
When the mask wearer wearing the transparent mask 100 breathes in, by the inhaling suction force, the discharge flip 132 of the air discharge means 130 closes the air discharge port 120′ while moving to an inner side, that is, in a direction of the transparent member 110 along the discharge movement guide protrusion 131′. Accordingly, it is possible to prevent the inflow of external air into the inside of the transparent member 110.
In addition, by the inhaling suction force, the inflow flap 142 of the air inflow means 140 opens the inflow through hole 143′ of the installation guide member 143 while moving to the inner side, that is, in a direction of the transparent member 110 along the inflow movement guide protrusion 141′ of the air inflow guide member 141. Accordingly, external air is introduced into the transparent member 110 through the air inflow port 120, and the mask wearer may breathe with the air introduced thereinto.
At this time, the inflow movement inner protrusion 141′ is provided in two stages, whereby the air inflow port 120 is not allowed to be closed even when the inflow flap 142 moves in the inward direction, thereby being allowed to guide the inflow of external air. In addition, since the external air flows in through the filter 144, it is possible to filter fine dust and bacteria included in the external air.
On the other hand, when the mask wearer breathes out, by the exhaling discharge force, the inflow flap 142 of the air inflow means 140 closes the inflow through hole 143′ of the installation guide member 143 while moving to an outer side, that is, in an opposite direction to the member 110 along the inflow movement guide protrusion 141′ of the air inflow guide member 141. Accordingly, it is possible to prevent the internal air of the transparent member 110 from being discharged.
In addition, by the exhaling discharge force, the discharge flip 132 of the air discharging means 130 opens the air discharge port 120′ while moving to the outer side, that is, in the opposite direction to the member 110 along the discharge movement guide protrusion 131′. Accordingly, air inside the transparent member 110 may be discharged.
While repeating the above process, the mask wearer may breathe in and breathe out even while wearing the transparent mask 100, thereby enabling smooth breathing and preventing dust or bacteria from being infiltrated in. In addition, since the shape of the mask wearer's mouth may be checked due to the transparent member 110, even the hearing impaired may identify the contents.
In addition, to describe the use process of another embodiment of the present disclosure, the transparent mask 100 is brought into close contact with a face of a mask wearer. At this time, the transparent mask 100 may cover the nose and mouth of the mask wearer, and the silicone 111 attached to the inner circumference of the transparent member 110 may be brought into close contact with the face.
While the transparent mask 100 is brought into close contact with the mask wearer's face, the transparent mask 100 may be worn by allowing the coupling member 110′ to be positioned on a mask wearer's head or to be hung on the mask wearer's ears. At this time, the silicone 111 attached to the inner circumference of the transparent member 110 by the coupling member 110′ is deformed and brought into close contact with the mask wearer's face, thereby preventing air from infiltrating in or leaking out.
When the mask wearer wearing the transparent mask 100 breathes in, by the inhaling suction force, the discharge flip 132 of the air discharge means 130 closes the air discharge port 120′ while moving to an inner side, that is, in a direction of the transparent member 110 along the discharge movement guide inner protrusion 131′. Accordingly, it is possible to prevent the inflow of external air into the inside of the transparent member 110.
In addition, by the inhaling suction force, the second inflow flap 182 of the second air inflow means 180 opens the second inflow through hole 183′ of the second installation guide member 183 while moving to the inner side, that is, in a direction of the transparent member 110 along the second inflow inner protrusion 181′ of the connection port 181. Accordingly, external air is introduced into the inside of the transparent member 110 through the air inflow port 120 via the second branch pipe 152 branched off from the air inflow pipe 150, and the mask wearer may breathe with the air introduced thereinto.
At this time, the second inflow movement guide protrusion 181′ is provided in two stages, whereby the second inflow flap 182 is unable to close the inside of the connection port 181 even when moved in the inward direction, thereby being allowed to guide the inflow of external air. In addition, since the external air flows in through the second filter 184, it is possible to filter fine dust and bacteria included in the external air.
On the other hand, when the mask wearer breathes out, by the exhaling discharge force, the second inflow flap 182 of the second air inflow means 180 closes the second inflow through hole 183′ of the second installation guide member 183, while moving to an outer side, that is, in an opposite direction to the member 110 along the second inflow inner protrusion 181′ of the second air inflow guide member 181. Accordingly, it is possible to prevent the internal air of the transparent member 110 from being discharged.
In addition, by the exhaling discharge force, the discharge flip 132 of the air discharging means 130 opens the air discharge port 120′ while moving to the outer side, that is, in the opposite direction to the member 110 along the discharge movement guide protrusion 131′. Accordingly, air inside the transparent member 110 may be discharged.
While repeating the above process, the mask wearer may breathe in and breathe out even while wearing the transparent mask 100, thereby enabling smooth breathing. The second air inflow means 80 may be provided with the second branch pipe 152 securing a certain length, whereby the air may be easily supplied thereto by positioning the second branch pipe 152 on an upper side of the water surface, at an outside of a workplace with a poor breathing environment, for example, a tank lorry, or at an outside of the window. To this end, the second air inflow means 180 may be provided with a floating body that may float on water, a weight that falls down to a lower side due to a gravitational action, a ring that may be fixed where necessary, or the like.
In addition, with reference to
In addition, the opening/closing ball 192 may also control the oxygen supply amount by pressing the opening/closing member coupled to the inside of the air movement hole 173 to control the opening area of the through hole inside the opening/closing member.
The forward and reverse rotation angles of the control valve 194 may be restricted by rotation control members 196 provided as a pair in the coupling member 171.
Oxygen supplied according to the control of the oxygen supply amount control part 190 is supplied to the inside of the transparent member 110 through the air inflow port 120 via the first branch pipe 151 and the air inflow pipe 150, and the mask wearer may breathe with the oxygen supplied into the inside of the transparent member 110.
As described above, the second air inflow means 180 and/or the oxygen cylinder 160 is connected to the transparent member 110, so it is possible not only to breathe by supplying external air and/or oxygen for a certain period of time in case of fire but also to prevent damage such as suffocation by toxic gas, poisoning by poisonous gas, and the like. In addition, the work environment may be improved because it is possible to breathe by receiving external air and oxygen even in a workplace with a poor breathing environment as well as to be able to work while staying in the workplace for a long time.
Since the filters contain carbon powder and copper powder, fine dust filtration and antibacterial, sterilizing, and deodorizing effects may be obtained, and after a certain period of time, additional filters may be added or replaced.
In the above, even though it has been described that all components constituting the embodiment of the present disclosure are combined or operated in combination, the present disclosure is not necessarily limited to this embodiment. That is, within the scope of the present disclosure, all the components may also be configured or operated by selectively combining one or more components. In addition, terms such as “include”, “compose”, or “have” described above mean that the corresponding component may be immanent unless otherwise stated, so it should be construed as being able to include other components further rather than excluding other components. All terms including technical and scientific terms have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs unless otherwise defined. Terms commonly used, such as those defined in the dictionary, should be interpreted as being consistent with the contextual meaning of the related art and are not interpreted in an ideal or excessively formal meaning unless explicitly defined in the present disclosure.
The above description is merely illustrative of the technical spirit of the present disclosure, and various modifications and variations will be possible without departing from the essential characteristics of the present disclosure by those skilled in the art to which the present disclosure pertains. Therefore, the embodiments disclosed in the present disclosure are not intended to limit the technical spirit of the present disclosure but to explain, and the scope of the technical spirit of the present disclosure is not limited by these embodiments. The protection scope of the present disclosure should be interpreted by the following claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present disclosure.
