Description

Personal Portable Fire Safety Gas Mask {Anti -Gas Mask}

The present invention facilitates escape to the emergency exit by preventing the blurring of the field of view by the smoke caused by the toxic gas or the toxic gas generated in the limited space of the laboratory or the room or the room or the smoke caused by the fire to facilitate escape to the emergency exit. It is about a "personal portable fire safety gas mask" that can protect the

As is well known, the gas mask or dust mask comprises a filtration chamber disposed at the front face seating nose and mouth area, a transparent material field securing part and a head strap reinforcement, and thus a harmful gas or toxic smoke generated in a fire or in various emergencies. These gas masks or dust-proof gas masks are mainly face-to-face and are expensive to manufacture due to the use of various parts. It was very difficult to keep on my back

In other words, we know that gas masks are effective from various toxic gases or toxic fumes in case of fire or emergency, but due to the problem of purchase cost, most of the places are not equipped with such gas masks. The loss of life due to suffocation increases due to

Accordingly, the present invention has been invented in view of the above-mentioned conventional problems, while lowering suction resistance while wearing, cleans the poisonous gas through the filter part cleanly, protects it from eye irritation, and easily secures the field of view, and is easy on any face shape. Its purpose is to provide a personal portable fire safety gas mask that can be worn and manufactured at low cost so that many unspecified people can be easily equipped and carried as emergency fire or safety facilities regardless of time and place. have

The present invention for achieving the above object is the upper surface and the left and right sides are closed and the lower surface is a wear cover that is opened with a wear hole and the wear member having a wear hole connected integrally with the bottom surface of the wear cover. It consists of a breathing filter part attached to the center of the front part of the cover paper along the transverse direction by means of a siring material, but the breathing filter part is the outermost flameproof, anti-toxic fabric and filter protection cloth carbon coated filter filter protection A contact nonwoven fabric contacting the nose and mouth of the fabric and the wearer is piled up in the order.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows an overall perspective view of an emergency gas mask according to the present invention.

According to the present invention, the upper and left and right sides of the front portion 1a and the rear portion 1b are closed and the lower portion thereof is integrally connected to the wearing cover opened with the wearing hole 2 and the lower portion of the wearing cover 1. Resilient member (3) having a hole (2) consists of a breathing filter (5) attached to the center of the front cover (1a) of the wearing cover (1) along the transverse direction through the sealing material (4) The respiratory filter unit 5 is a non-woven fabric for flame retardant and anti-gas treatment 6 which is in contact with the outside air, followed by a filter protective cloth 7a, a carbon-coated filter 8, a filter protective cloth 7b, and a wearer's nose and mouth. Laminated in contact with the nonwoven fabric (9) in contact with the part in turn and the flame-resistant silicone tightening band (10) is built-in sewing around the wearing hole (2) of the elastic member (3)

In addition, the entirety of the wearing cover 1 is made of a material such as polyvinyl of transparent or light color. As a matter of course, not only such a material but also a material of a similar flame retardant system may be used, so that the visual field may be absorbed when worn. Of course it is very easy to secure

In addition, the non-woven fabric 6 for flame retardant and anti-gas treatment 6 of the respiratory filter unit 5 and other non-woven fabrics and filters 8 stacked thereon are made of a material capable of lowering respiratory resistance and have gas repellent and flameproof dustproof functions.

Meanwhile, when the wear cover 1 is worn on the face by the wearer 2, the elastic cover 3 and the tightening band 10 of the elastic material having good elasticity can be easily worn on various faces. Furthermore, when worn, the tightening band 10 of the wearing hole 2 has adhesiveness so as to suitably fit to various neck circumferences of the wearer and the wearing cover 1 is in the form of a substantially rectangular bag in the present invention. However, if necessary, the design can be changed to round circle or other polygonal bag shape.

The present invention can be easily worn by the person wearing the glasses to protect themselves from toxic gases in an emergency or fire without taking off the glasses.

In addition, in the present invention, since the wear cover 1 is made of a material such as flame retardant polyvinyl chloride, it can be easily stored and utilized regardless of a place, and the wear cover pocket or other carrying bag of the wearer can be folded as needed. There is also an advantage that you can carry it and wear it when toxic gas is generated.

As described above, the personal portable fire safety gas mask according to the present invention can clean the toxic gas cleanly by a filter unit having a low suction resistance to protect the wearer from various toxic gases generated in an emergency such as a fire, and easily secure a visual field. In addition, anyone can easily wear it, and in particular, by lowering the manufacturing cost, it is an emergency fire-fighting or safety facility that can be used easily regardless of the location and carrying it anywhere.
