The adsorption filter 170 may be a filter serving to remove moisture or odor in the first fluid space S1. In addition, the adsorption filter 170 can enhance the emotional quality of the user by providing natural harmless harmless to the user's respiratory apparatus.

More specifically, the adsorption filter 170 shields the body through-hole 111 so that the first fluid space S1 and the second fluid space S2 are disposed so as not to communicate with each other except the above- .

FIG. 10 is an exploded perspective view showing the mask body 110 and the flap valve 150 in the configuration of FIG. 7, and FIG. 11 is a cutaway perspective view taken along line B-B of FIG.

The air discharged by the user's breath moves from the first fluid space S1 to the second fluid space S2 opened by the flap valve 150 as shown in Figs. 7 and 8, And is discharged to the outside through the slit 125.

Thus, in an embodiment of the face mask 100 according to the present invention, the flap valve 150 may be configured such that only air that is closed during the inspiration action of the user and purified by the air purification unit 1 is supplied to the user &apos; Way valve that opens when the user exhales and exhales the user's breath.

However, when the purified air supplied from the air-cleaning unit 1 is in an emergency situation in which the connection pipe 90 malfunctions or the user needs more intake air, the flap valve 150, which is a one-way valve, It is possible to provide the inconvenience of forcibly removing the face mask 100 according to the present invention.

Accordingly, in an embodiment of the face mask 100 according to the present invention, the flap valve 150 is configured to allow the first fluid space S1 and the second fluid &lt; RTI ID = 0.0 &gt; And to open the space S2 in an emergency.

One side free end 151 and the other free side end 152 are connected to the inner surface of the mask shell 120 and the inner surface of the mask body 110 in the second fluid space S2 according to the pressure change of the first fluid space S1. As shown in Fig. At this time, one free end 151 and the other free end 152 may be formed to have a thickness that only a part of the end portion (tip end portion) is bent.

Therefore, when the pressure of the first fluid space S1 increases due to the user's exhalation, one side communication hole 116 and the other side communication hole 117 are connected to one side free end portion covering the outer side surface of the mask body 110 The end portion of the first free end 152 and the free end 152 of the second free end 152 can simultaneously flow into the second fluid space S2 from the first fluid space S1 and the second fluid space S2 May be exhausted to the outside through an exhaust slip provided in the mask shell 120. [ Here, the other free end 152 for the emergency valve may be configured to have a low flexibility with respect to the free end of one side, and thus may be opened during the exhalation or may maintain the closed state.

When the first fluid space S1 is depressurized by the user's suction, one side communication port 116 and the other side communication port 117 are connected to each other by one side free end 151 and the other side free side 152, The purified air of the air purifying unit 1 which is separately provided is flowed into the first fluid space S1 through the air inlet 113. [

However, there may be a case where the pressure in the first fluid space S1 is reduced to a predetermined pressure or lower due to a sudden dyspnea, a lack of oxygen, a problem in an air purification unit, or the like. At this time, the air introduced into the first fluid space S1 may be an emergency state in which not only the purified air supplied by the air-cleaning unit 1 but also the communication hole 115 is opened, and the emergency valve is opened Needs to be. Here, the predetermined pressure is not limited, and may be, for example, a sudden pressure that the user suddenly sucks.

6, the tip of the other free end 152 for the emergency valve is bent toward the first fluid space S1 side in the above-described emergency situation It is necessary to allow emergency opening.

One free end for the exhalation valve must be easily bent and opened at the time of exhalation and must be quickly closed upon intake, so that the flexibility of the flap valve should be high. For this purpose, it is recommended that the flap valve is made thinner than the emergency valve flap valve. In addition, it is preferable that the exhalation valve is maintained in a closed state even during normal intake or emergency situations. To this end, even if the reduced pressure of forming the first fluid space is reduced to the predetermined pressure or less in one side communication port for the exhalation valve, A support rib 116a for preventing the free end portion from being bent toward the first fluid space side may be formed. The supporting ribs 117a may be formed so as to cross the other communication hole 117 vertically.

The other free end for the emergency valve should be less flexible than one free end for the exhalation valve to prevent emergency opening during routine intake and the other free end for the emergency valve should be thicker than one free end for the exhalation valve Lt; / RTI &gt;

The reinforcement rib 152a may be formed in one region of the other free end portion of the emergency valve to further prevent the emergency opening during the normal intake. The reinforcing rib may prevent the other free end portion of the emergency valve from being bent toward the first fluid space when the forming pressure of the first fluid space is less than the predetermined pressure.

Figure 12 is a case of another embodiment in which there is one flexible flap valve, in which the flap valve acts as an exhalation valve that is bent in the direction of the second fluid space and closed at the time of inspiration, The flexible flap valve is bent into the first fluid space through the communication hole to be opened so that the first fluid space and the second fluid space can be opened to allow intake It can also be configured to serve also as an emergency valve.

As described above, the face mask 100 according to an embodiment of the present invention has an effect of improving usability and convenience because it can be easily worn on a user's body together with an air purification unit for purifying and supplying outside air, , The emergency valve is opened according to the degree of pressure reduction in the first fluid space provided by the user's intake when an urgent situation occurs such that a large amount of intake is required during wear of the user or a problem occurs in the inflow of air from the air purification unit The present invention has the effect of preventing the occurrence of a safety accident at the time of a similar accident by allowing an emergency intake, and it is possible to improve the quality of user's sensibility by removing moisture and odor in the air (first fluid space) .
