1, a mouth-nose mask 10 made of a heat-resistant synthetic resin or rubber is configured to cover both the mouth and nose of a user, and has an oval cylindrical body 11, one side of which is the user. The face (particularly, it has a pad portion 12 capable of completely sealingly covering from the root portion of the nose to the lips and the jaw portion, and has a mounting opening 13 formed on the other side, which will be described later. That is, the portion in which the filtering substance or the like is stored) is detachably mounted or is non-detachably fixed.
An exhaust valve 30 is mounted below one of the side surfaces in a portion near the pad portion 12. Although the detailed structure of the exhaust valve 30 will be described later, the exhaust valve 30 is configured to allow only exhaust and not to inhale gas from the outside.

る。Next, a mounting opening 13 is formed on the side opposite to the pad portion 12, and the mounting opening 13 is formed.
The canister 20 is attached to the above as described above. This canister 20 has a three-layer structure having a function of detoxifying poisonous gas (for example, carbon monoxide, hydrogen cyanide, hydrogen chloride, formaldehyde, nitrogen dioxide, ammonia, benzene, hydrogen sulfide, sulfur dioxide, etc.).
That is, as shown in FIG. 2, the adsorption layer 21, the filter layer 22, and the catalyst layer 23 are sequentially formed from the outside.
It is desirable that the adsorption layer 21 is made of synthetic zeolite or an activator, the filter layer 22 is made of non-woven fabric (chemical fiber system), and the catalyst layer 23 is made of heavy metal or metal catalyst. However, the structure of the canister 20 itself may be selected from known structures and a desired structure may be adopted. It should be noted that the canister 20 itself can be replaced so that it can be recycled, which is convenient. However, it is necessary to pay sufficient attention to coupling the canister 20 and the mounting opening 13 of the tubular body 11, and it is necessary to configure the structure so as to have a hermeticity.

As shown in FIGS. 3 (A) and 3 (B), the exhaust valve 30 is provided between an inner member 31 and an outer member 32 which are engaged with each other, and between them. And a movable seal member 33 located. The movable seal member 33 elastically comes into close contact with the outer protruding portion of the inner member 31 to normally block the air flow, and only when an air pressure higher than a predetermined air pressure is applied, the movable seal member 33 is directed toward the outer member 32 side. It is configured to move so as to bulge to form a gap, and thus to move and operate when the air pressure in the mask 10 becomes higher than a predetermined value due to the exhaust of the user.

The shaft portion 37 has a hole 38 at the center thereof, and the support pin 40 of the movable seal member 33 is held in an elastically sealed state. The movable seal member 33 has a disc-shaped valve body 41 made of a soft plastic material as shown in the drawing, and a support pin 40 is integrally formed at the center of the disc-shaped valve body 41. The stop projection 42 is elastically fitted and attached to the hole 38 of the shaft portion 37. And this valve body 41
Is normally in close contact with the edge of the engaging projection 35. However, when the air pressure from the direction of the flange portion 34 (that is, the pressure due to the exhaust of the user) is applied, the flatness of the valve body 41 is maintained while the engagement between the engagement protrusion 42 and the hole 38 is maintained as it is. The portion 41a moves slightly away from the end edge of the engaging projection 42 by the air pressure so as to bulge toward the outer member 32 side, and forms a gap between the two (the valve body 41 and the end edge of the engaging projection 35). As a result, the exhaust gas is pushed out through the windows of the outer member 32.

Is screwed together. Thus, as shown in FIG.
The inner member 31 and the outer member 32 are arranged on the inner side and the outer side with the wall portion 1 sandwiched therebetween, and are detachably coupled to each other. Thereby, the exhaust gas can be discharged to the outside by the exhaust pressure of the user, while the invasion of air (namely, toxic gas) from the outside is prevented by the action of the valve body 41.
