In addition, in describing the embodiment of the present disclosure, when it is determined that a detailed description of a related known configuration or function interferes with the understanding of the embodiment of the present disclosure, the detailed description thereof will be omitted.

[0039] In addition, in describing components of the embodiment of the present disclosure, terms such as first, second, A, B, (a), (b), and the like may be used. Such terms are only for distinguishing components from other elements, and the essence, order, or order of the components are not limited by the terms. When it is described that a component is connected, coupled, or combined with another component, the component may be directly connected, coupled, or combined with another component, but another component may be connected, coupled, or combined between each component.

[0040] 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.

[0041] FIG. 1 is a perspective view of a transparent mask equipped with an oxygen supply means according to an example of the present disclosure.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] With reference to FIG. 2, the transparent mask may further include an air discharge means 130 provided in the air discharge port 120. The air discharge means 130 may include an air discharge guide member 131, a discharge flap 132, and an air discharge fastening member 133.

[0049] 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.

[0050] 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.

[0051] 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. When damaged or aged, the discharge flap 132 may be replaced with a new one after disassembling the air discharge fastening member 133.

[0052] With reference to FIGS. 3 and 4, the transparent mask may further include an air inflow means 140 provided in the air inflow port 120. The air inflow means 140 may include an air inflow guide member 141, an inflow flap 142, an installation guide member 143, a filter 144, and an air inflow fastening member 145.

[0053] The air inflow guide member 141 is a cylindrical member and may be coupled 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. On the outer peripheral surface of the air inflow guide member 141, a screw may be provided, or a latching portion may be provided. An inner circumferential surface of the air inflow guide member 141 may be provided with an inflow guide protrusion 141 radially shaped thereon or may be provided without the inflow guide protrusion 141 thereon. A hole may be provided by passing through the inside of the air inflow guide member 141, that is, the surface brought in contact with the transparent member 110, entirely, or by passing through only a portion corresponding to the air inflow port 120. The inflow movement guide protrusion 141 may be provided in two stages or may be provided in one stage on the inner side, that is, on a side toward the air inflow port 120. An inflow flap 142 to be described later may be located on the outer side of the inflow movement guide protrusion 141 of the inner side, that is, a position of the inflow movement guide protrusion 141 of the outer side.

[0054] 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.

[0055] 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 installation guide member 143 may be coupled to the air inflow guide member 141 by having a screw or a latching portion provided on the inner circumferential surface of an inner side. The installation guide member 143 may have a screw or a latching portion provided on the outer circumferential surface. The inner peripheral surface of the first space is fastened to the air inflow guide member 141 and is brought into close contact with the same, thereby preventing the inflow flap 142 from being separated. The second space may accommodate a filter 144 to be described later.

[0056] The filter 144 filters foreign substances contained in the incoming air and may be installed in the second space of the installation guide member 143. The filter may include carbon powder and copper powder. In the filter, a carbon filter layer containing carbon powder on a nonwoven fabric, woven fabric, sponge, and the like, and a copper filter layer containing copper powder on a nonwoven fabric, woven fabric, sponge, or the like may be overlapped. The carbon filter layer and the copper filter layer may be added or replaced.

[0057] The air inflow fastening member 145 is fastened to the installation guide member 143 to fix the filter 144.

[0058] With reference to FIG. 5, the transparent mask may further include an air inflow pipe 150 having one side coupled to the air inflow port 120. The air inflow pipe 150 may be provided with a flexible material. The air inflow pipe 150 may be directly coupled to the transparent member 110 by attachment, fusion, or the like, or coupled to the air inflow guide member 141 of the air inflow means 140. An opposite side of the air inflow pipe 150 may include a first branch pipe 151 and a second branch pipe 152 that are branched off. The first branch pipe 151 is provided with a coupling assembly 170 to which an oxygen cylinder 160 is coupled so that oxygen may be supplied from the oxygen cylinder 160. The second branch pipe 152 may be provided with a second air inflow means 180.

[0059] With reference to FIG. 6, the coupling assembly 170 may include a coupling member 171 and a coupling pipe 172 with a configuration to be able to detach from the oxygen cylinder 160.

[0060] The coupling member 171 may be mounted on the oxygen discharge part 161 of the oxygen cylinder 160. Wings coupled to wing grooves of the oxygen cylinder 160 may be provided at end portions under the coupling member 171. The wings are provided as a pair and are coupled to the oxygen cylinder 160 to maintain bonding force with the oxygen cylinder.

[0061] The coupling tube 172 has a tubular shape, and an air movement hole 173 may be provided therein. The injection nozzle 162 of the oxygen cylinder 160 may be coupled to an inner end portion of the air movement hole 173.

[0062] With reference to FIG. 7, the second air inflow means 180 may include a connection port 181, a second inflow flap 182, a second installation guide member 183, a second filter 184, and a second air inflow fastening member 185. The second air inflow means 180 is similar to the above-described air inflow means 140. Therefore, omitted parts may refer to the air inflow means 140.

[0063] The connection port 181 of the second air inflow means 180 may be coupled by being fitted, attached, bonded, or fusion-bonded to the second branch pipe 152 or integrally provided with the second branch pipe 152, and a screw or a latching portion may be provided on an outer circumferential surface thereof. The connection port 181 is a cylindrical member, and an inner circumferential surface of the connection port 181 may be provided with a second inflow movement guide protrusion 181 radially shaped thereon or may be provided without the second inflow inner protrusion 181. A hole may be provided by passing through only a portion of the inner side of the connection port 181, that is, a surface being brought into contact with the second branch pipe 152. The second inflow inner protrusion 181 may be provided in two stages or may be provided in one stage on an inner side of the connection port 181, that is, the side of the second branch tube 152. A second inflow flap 182 to be described later may be located on an outer side of the second inflow movement guide protrusion 181 of an inner side.

[0064] 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.

[0065] 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 inner peripheral surface of the third space is fastened to the connection port 181 and is brought into close contact with the same, thereby preventing the second inflow flap 182 from being separated. The fourth space may accommodate a second filter 184 to be described later.

[0066] The second filter 184 filters foreign substances contained in the incoming air and may be installed in the fourth space of the second installation guide member 183. The second filter 184 may include carbon powder and copper powder. In the second filter 184, a carbon filter layer containing carbon powder on a nonwoven fabric, woven fabric, sponge, and the like, and a copper filter layer containing copper powder on a nonwoven fabric, woven fabric, sponge, or the like may be overlapped. The carbon filter layer and the copper filter layer may be added or replaced.

[0067] The second air inflow fastening member 185 is fastened to the second installation guide member 183 to fix the second filter 184.

[0068] In addition, with reference to FIG. 6, the transparent mask further includes an oxygen supply amount control part 190 provided in the coupling assembly 170, wherein the oxygen supply amount control part 190 may include an opening/closing hole 191, an opening/closing ball 192, a spring 193, a control valve 194, and a fixing ring 195.

[0069] The opening/closing hole 191 may be a hole penetrating through the coupling pipe 172 so as to communicate with the air movement hole 173.

[0070] The opening/closing ball 192 is mounted in the opening/closing hole 191 to open and close large or small the air movement hole 173 according to the rotation of the control valve 194.

[0071] The spring 193 may elastically support the control valve 194 mounted on the coupling pipe 172.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] The following describes the process of using one embodiment of the present disclosure.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] In addition, with reference to FIG. 9, the coupling assembly 170 may be connected to the first branch pipe 151 branched off from the air inflow: pipe 150, and an oxygen cylinder 160 may also be installed in the coupling assembly 170 to be used. For the oxygen stored in the oxygen cylinder 160, when the control valve 194 of the oxygen supply amount control part 190 is rotated in forward and reverse directions, the curved control surface inside the control valve 194 presses the opening/closing ball 192, and the opening/closing ball 192 may control the oxygen supply amount by controlling the open area of the air movement hole 173 of the coupling assembly 170 while moving along the opening/closing hole 191.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.
