Description

The present invention relates to a smoke and gas mask, and more particularly to a smoke and gas mask that can be easily and correctly worn in a short period of time in an emergency.

Conventional smoke and gas masks include a hood that covers the entire head of the user, a cylindrical body with a pad that touches the user's face, and an opening on the opposite side of the pad that is attached to the mask. A smoke-proof mask is known that is equipped with a smoke-proof canister and can be used as a countermeasure against toxic gas/smoke and oxygen deficiency in the event of a fire for a relatively long time (see, for example, Patent Document 1).

In addition, it includes a facepiece that is tightly fixed to the wearer's face, a headband that fixes the facepiece to the wearer's face, and an absorbent that is detachably attached to the facepiece and that contains an absorbent that can adsorb toxic components. A smoke-proof and gas-proof mask equipped with a can is disclosed (see, for example, Patent Document 2).

According to the smoke mask described in Patent Document 1, the hood protects the user's nose, mouth, and eyes and can be used for a relatively long time. However, it is difficult for ordinary people who are not accustomed to wearing smoke masks to properly put on the hood and the cylindrical body in a short period of time in an emergency. In addition, since it is relatively large, manufacturing costs are high, and it is also bulky when stored, and a large storage space is required to store a large amount of smoke masks.

In addition, in the smoke and gas masks of Patent Document 2, the absorbent contained in the absorption can generally tends to have a short effective life when it comes into contact with air, so when not in use, the absorbent contained in the absorption can It is necessary to seal the mask in a sealed plastic bag, etc., and to attach it to the facepiece after opening the plastic bag before use. Therefore, there has been a problem in that valuable time in an emergency is wasted in opening the plastic bag, attaching it to the mask, and putting on the gas mask. Furthermore, since the facepiece is worn by placing the headband on the back of the head and fixing it, it may take time for people who are not used to wearing headbands to properly wear it.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to enable ordinary people who are not accustomed to wearing smoke and gas masks to wear them easily and correctly in an emergency situation. To provide a smoke-proof and gas-proof mask capable of storing a large amount of smoke-proof and gas-proof masks compactly even in a relatively narrow space.

The above object of the present invention is achieved by the following configuration.
(1) A facepiece that is attached to the user's face to cover the user's nose and mouth and has an intake hole and an exhaust hole, and a facepiece that contains an absorbent capable of adsorbing toxic components and is connected to the intake hole. an absorption canister integrally fixed to the
ear straps for attaching the facepiece closely to the user's face;
an airtight container in which the facepiece, the absorption canister, and the ear strap are housed in a state where they are assembled together and are shielded from the outside air;
Smoke and gas masks.

According to the smoke and gas masks of the present invention, even ordinary people who are not accustomed to wearing smoke and gas masks can easily and correctly wear them in a short time in an emergency. Additionally, in case of an emergency, a large amount of smoke and gas masks can be compactly stored in a relatively small space. Therefore, it is suitable for keeping on hand in buildings such as apartments and offices, hotels, hospitals, nursing homes, etc. in case of fires or earthquakes.

FIG. 1 is a perspective view of a smoke and gas mask according to the present invention. FIG. 2 is a cross-sectional view of a check valve provided in an intake hole and an exhaust hole of a smoke and gas mask.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a smoke-proof and gas-proof mask according to the present invention will be described in detail below based on the drawings.

As shown in FIG. 1, the smoke and gas mask 10 of this embodiment includes a facepiece 20 that is attached to the user's face, an absorption canister 30 that is integrally fixed to the facepiece 20, and a mask 20 that is attached to the user's face. and an ear hook string 40 for attaching and holding the ear hook to the ear. The facepiece 20 to which the absorption canister 30 is integrally fixed is housed in the airtight container 50 together with the ear strap 40 in a state where it is shielded from the outside air.

The face piece 20 is, for example, integrally formed with a front face piece 21 made of hard plastic and a rear face piece 22 made of soft plastic. The front end of the front face piece 21 is formed in the shape of a pipe 23 extending outward, and the pipe 23 communicates the inside and outside of the face piece 20. A partition wall 25 having a plurality of intake holes 24 is provided at the front end of the pipe 23 (see FIG. 2).

An intake check valve 45 that opens toward the inside of the front face piece 21 is disposed on the inner surface of the partition wall 25 . As shown in FIG. 2, the valve body 46 of the check valve 45 is made of an elastic member such as rubber, and includes a flange portion 47 that covers the intake hole 24, and a head formed protruding approximately at the center of the flange portion 47. A mounting boss 48 is provided. The head 48a of the headed attachment boss 48 is formed to have a larger diameter than the attachment hole 26 of the partition wall 25.

The valve body 46 is attached to the partition wall 25 in such a manner that the head 48a of the headed mounting boss 48 is inserted into the mounting hole 26 of the partition wall 25 and is prevented from coming off. As a result, the flange portion 47 of the valve body 46 comes into airtight contact with the inner surface of the partition wall 25 due to elastic force, allowing air to flow from the outside into the pipe 23, and preventing air from flowing from inside the pipe 23 to the outside. to prevent

Further, a part of the face piece 20 is provided with an exhaust hole 27 consisting of a plurality of elongated holes. The exhaust hole 27 also communicates the inside of the face piece 20 with the outside (outside air). A partition wall (not shown) having a plurality of exhaust holes is provided inside the exhaust hole 27 . A check valve 45 for exhaust is provided on the outside of the partition wall. The exhaust check valve 45 prevents the flow of air from the outside to the inside of the face piece 20, and allows the flow of air from the inside to the outside.

Note that the intake check valve and the exhaust check valve have substantially the same structure, although the direction in which the valve body 46 is attached to the partition wall is opposite, so a detailed description thereof will be omitted.

As a result, when the pressure inside the face piece 20 decreases due to air intake by the user, the flange portion 47 separates from the partition wall 25 and external air flows into the inside of the face piece 20 . Further, when the pressure inside the face piece 20 increases due to the user's exhalation, the exhaust check valve 45 opens and the air is exhausted to the outside.

The rear face piece 22 has a large opening toward the rear and has a size and shape that can cover the user's mouth and nose. Furthermore, since the rear face piece 22 is made of soft plastic, it comes into close contact with the user's face when worn.

The absorption canister 30 contains an absorbent 31 capable of adsorbing toxic components, such as activated carbon or activated carbon carrying (impregnating or impregnating) a substance that reacts with the toxic components. The absorption canister 30 has ventilation holes 32 on its front and rear surfaces, and is integrally connected to the pipe 23 of the front face piece 21. The absorption canister 30 may be fixed by screwing onto the pipe 23, or may be fixed by adhesive.

Both ends of an elastic ear strap 40 made of loop-shaped rubber or the like are fixed to both side surfaces of the face piece 20, respectively. The smoke and gas mask 10 can be worn on the user's face by hanging the ear straps 40 around the user's ears.

The airtight container 50 is for storing the smoke-proof and gas-proof mask 10 while being isolated from the outside air, and is made of, for example, a plastic bag that can maintain an airtight state. Then, the face piece 20, absorption canister 30, and ear strap 40 assembled together are stored in an airtight state. The airtight container 50 can prevent the performance of the absorbent 31 from deteriorating by storing the smoke and gas mask 10, especially the absorption canister 30 containing the absorbent 31, shielded from the outside air.

Next, the usage and operation of the smoke and gas mask 10 of this embodiment will be explained. The smoke and gas mask 10 of this embodiment is always kept in buildings such as apartments and offices, hotels, hospitals, nursing homes, etc., and is used in the event of a disaster or fire. Since the smoke and gas masks 10 of this embodiment are formed in a relatively small size, a large number of smoke and gas masks 10 can be stored in a narrow storage space.

When using the smoke and gas mask 10, take out the smoke and gas mask 10 together with the airtight container 50 from the storage location, open the airtight container 50 such as a plastic bag, and remove the assembled facepiece 20 and gas absorbent. Take out the can 30 and the ear strap 40. Then, the opening of the rear face piece 22 made of soft plastic is pressed against the face (mouth and nose), and the ear strap 40 is hung around the ear.

In this way, to put on the smoke and gas mask 10, simply take out the smoke and gas mask 10 from the airtight container 50, and hang the ear straps 40, which are widely known how to use masks, around your ears. Since it is extremely simple, even an ordinary person who is not accustomed to wearing the smoke and gas mask 10 can easily and correctly wear it in a short time even in an emergency.

After wearing the smoke and gas mask 10, when the user breathes, the air containing toxic components outside the smoke and gas mask 10 is adsorbed by the absorbent 31, and the harmless air is taken in. The user's breathing is ensured.

Note that the present invention is not limited to those illustrated in the above embodiments, and can be modified as appropriate without departing from the gist of the present invention.
