Here, the one free end 151 and the other free end 152 may have an inner surface and a mask body 110 of the mask envelope 120 in the second fluid space S2 according to the pressure change of the first fluid space S1. It may be provided with a flexible flap bent between the outer surface of the). In this case, the one free end 151 and the other free end 152 may be formed to have a thickness in which only a portion of the end portion (tip) is bent.

Therefore, when the pressure of the first fluid space (S1) increases due to the exhalation of the user, one side free end covering the one side communication port 116 and the other side communication port 117 on the outer side of the mask body 110 151 and the other end of the free end 152 is simultaneously lifted so that the user's exhaled air can flow from the first fluid space (S1) to the second fluid space (S2), the second fluid space (S2) The air flowed into) may be exhausted to the outside through the discharge slip provided in the mask envelope 120. Here, the other free end 152 for the emergency valve may be configured to have a weaker flexibility than the one free end, and thus may be opened during exhalation and may remain closed.

In addition, when the first fluid space S1 is depressurized by the intake of the user, the one free end 151 and the other free end 152 are masked on one side communication port 116 and the other communication port 117. It is closed while covering the outer surface of the body 110, the purified air of the separately provided air purification unit 1 is introduced into the first fluid space (S1) through the air inlet (113).

However, there may occur a case where the pressure in the first fluid space S1 is emergency reduced under a predetermined pressure due to a sudden difficulty in breathing, lack of oxygen, a problem of an air purification unit, or the like. In this case, the air flowing into the first fluid space S1 may be an emergency situation in which not only the purified air supplied by the air purification unit 1 but also flows through the communication port 115, and the emergency valve is opened. Needs to be. Here, the predetermined pressure is not limited, and may be, for example, a pressure suddenly reduced by the user inhaling abruptly.

One free end for the exhalation valve should be easily bent and open during exhalation and should be closed quickly during inspiration, so the flexibility of the flap valve should be high. For this purpose, it is better to configure a thinner thickness than the flap valve for the emergency valve. In addition, it is preferable to maintain the exhalation valve in a closed state even at the time of daily intake or emergency, and for this purpose, the one side communication port for the exhalation valve is formed on the one side of the exhalation valve even when the decompression of the first fluid space is reduced to below the predetermined pressure. A support rib 116a may be formed to prevent the free end from bending open toward the first fluid space. The support rib 117a may be formed to traverse the other side communication port 117 up and down.

The other free end for the emergency valve must be less flexible than the one free end for the exhalation valve to prevent emergency opening during normal intake, and the other free end for the emergency valve is thicker than the one free end for the exhalation valve. Can be configured.

In order to further prevent emergency opening during daily intake, a reinforcing rib may be formed in one region of the other free end for the emergency valve. The reinforcing rib can prevent the other free end of the emergency valve from being bent into the first fluid space side when the forming pressure of the first fluid space is less than the predetermined pressure.

FIG. 12 illustrates another embodiment in which one flexible flap valve exists, and serves as an exhalation valve in which the flap valve is bent in the direction of the second fluid space to open and closes upon inspiration when exhaled. In an emergency situation where the space is depressurized below a predetermined negative pressure, the flexible flap valve is bent and rolled into the first fluid space through the communication port to emergencyly open the first fluid space and the second fluid space to allow intake. It can be configured to serve as an emergency valve.

As described above, the embodiment 100 of the face mask according to the present invention has an effect of improving usability and convenience since outdoor activities are possible by simply wearing it on a user's body together with an air purification unit for purifying and supplying external air. In case of an emergency situation such as a large amount of intake required while wearing the user or a problem of inflow of air from the air purification unit, an emergency valve is opened according to the degree of decompression in the first fluid space provided by the intake of the user. By enabling emergency intake, it is possible to prevent the occurrence of a safety accident in case of emergency, and improves user's emotional quality by removing moisture and odor in the air (first fluid space) of the user's respirator.
