There are disadvantages.

The high-function type mask has the advantages of not having difficulty in breathing and not easily forming moisture because the air is circulated smoothly because the air is inhaled and discharged separately by the air purification means and the exhaust means, while the disadvantage of being expensive there is.

However, since the mask covers the mask wearer's face (nose part and mouth part), the facial expression of the mask wearer cannot be seen.

In addition, in the case of deaf people who are deaf and cannot hear sounds, there is a problem in that communication is not performed because the shape of the mouth cannot be confirmed.

In order to solve the above problems, in recent years, a film-type transparent transparent mask has been registered in Korean Patent Registration No. 10-1681100.

Thus, it is introduced into the transparent member 110 through the air inlet 120, and the mask wearer can breathe with the introduced air.

At this time, the second inlet movement inner protrusion 181 ′ is formed in two stages, so that the inside of the connector 181 cannot be closed even when the second inlet flap 182 moves inward to guide the inflow of external air. 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 exhales, the second inlet flap 182 of the second air inlet means 180 by the exhaling force causes the second inlet during the second inflow of the second air inlet guide member 181, the protrusion 181 ') to the outside, that is, to prevent the internal air discharge of the transparent member 110 by closing the second inlet through hole 183' of the second installation guide member 183 while moving in the opposite direction to the transparent member 110. can

In addition, the discharge flip 132 of the air discharging means 130 by the exhaling force moves outward along the discharging protrusion 131 ′, that is, in the opposite direction to the transparent member 110 while moving the air outlet 120 ′. By opening it, the inside air can be exhausted.

While repeating the above process, the mask wearer can inhale and exhale even while wearing the transparent mask 100 , thereby enabling smooth breathing. The second air inlet means 180 secures the second branch pipe 152 for a certain length and places it on the upper side of the water surface, outside of a workplace with poor breathing environment, for example, a tank lorry, or outside the window, Air can be easily supplied. To this end, the second air inlet means 180 may be provided with a floating body that can float on water, a weight that falls downward due to gravity, or a ring that can be fixed where necessary.

In addition, referring to FIG. 9 , a coupling port 170 is connected to the first branch pipe 151 branched from the air inlet pipe 150 , and an oxygen cylinder 160 is installed in the coupling port 170 to be used. may be The oxygen stored in the oxygen cylinder 160 rotates the control valve 194 of the oxygen supply amount control unit 190 in forward and reverse directions while the curved control surface inside the control valve 192 presses the opening/closing ball 192, The opening/closing ball 192 can control the oxygen supply amount by adjusting the open area of the air movement hole 173 of the coupling hole 170 while moving along the opening and closing hole 191 . In addition, the opening/closing ball 192 may adjust the oxygen supply amount by pressing the opening/closing member coupled to the inside of the air moving hole 173 to adjust the opening area of the through-hole inside the opening/closing member.

The forward and reverse rotation angles of the control valve 192 may be rotated within the rotation control member 196 provided as a pair in the coupling member 171 .

Oxygen supplied according to the control of the oxygen supply control unit 190 is supplied into the transparent member 110 through the air inlet 120 via the first branch pipe 151 and the air inlet pipe 150, With the oxygen supplied into the transparent member 110 , the mask wearer can breathe.

As described above, since the second air inlet means 180 and/or the oxygen cylinder 160 is connected to the transparent member 110 as described above, it is possible to breathe by receiving external air and/or oxygen for a certain period of time during a fire as well as toxic gas. It can prevent damage such as suffocation and poisoning by poisonous gas. In addition, it is possible to improve the working environment because it is possible to breathe by receiving external air and oxygen even in a work place with a poor breathing environment, as well as to be able to work while staying in the work place for a long time.

Since the filters contain carbon powder and copper powder, fine dust filtration and antibacterial, sterilizing, and deodorizing effects can be obtained, and after a certain period of time, additional filters can be added or replaced.
