Description

Hood for Fire Evacuation {SHUNTING FIRE HOOD}

The present invention relates to a hood for evacuation of fire, and in particular, to improve the productivity by manufacturing the front and rear parts by sewing and gluing, antifog coating on the viewing window to prevent the blurring and to contact the face and head The present invention relates to a fire evacuation hood that has a soft lining to reduce discomfort when worn and obtains excellent dehumidification, dedusting, detoxification and deodorization performance by a composite filter.

In general, in the case of large-scale fire events such as the recent subway fire disaster, such as the recent Daegu subway fire disaster, the cause of death is mostly caused by toxic gas rather than by direct flame, and most of the victims do not have visibility due to toxic gas. Or inhaled by poisonous gas.

In foreign countries, a personal mask that can be lightly carried in the case of fire has been developed to reduce the mortality rate caused by the inhalation of smoke in the event of a fire. At the same time, there was a problem in that the visibility of the visor part was blurred due to steam, and the vision was blurred. Productivity was low, and a simple type of purification filter was employed to prevent the contaminated air's ability to clean contaminated air at the fire site. There was this.

The present invention devised to solve the problems and defects of the prior art as described above, to improve the productivity by manufacturing the front and rear parts by sewing and bonding method, anti-fog coating on the viewing window to perform anti-fogging treatment In addition, the purpose of the present invention is to provide a fire evacuation hood that reduces the discomfort when worn by coating a soft lining on the contact surface of the face and the head, and obtains excellent dehumidification, dedusting, detoxification, and deodorization performance by the composite filter.

In order to achieve the above object, the hood for evacuation of the fire according to the present invention is bonded to the periphery of the front plate and the rear plate of rubber material such as polychloroprene, the neck portion is formed thinner than the upper portion for elasticity, the front plate The upper opening is formed of a polycarbonate material and the like is attached to the anti-fog coating for the anti-fog coating, and a pair of lower openings formed to be located on both sides of the lower outlet is attached to the composite filter.

In addition, the inner surface of the front plate of the hood portion is configured to coat the lining so as to gently contact the face portion and the head.

In addition, the composite filter is laminated with a mesh for protection of the filter, an electrostatic filter for filtering smoke, an active carbon filter for removing various harmful elements and deodorizing and deodorizing, a catalyst filter for detoxifying CO, and a reinforcing cloth for reinforcement. The part is joined.

Hereinafter, with reference to the accompanying drawings of the present invention in detail as follows.

1 to 4 is a view of the fire evacuation hood according to the present invention, Figure 1 is an external configuration of the fire evacuation hood, Figure 2 is an internal configuration of the fire evacuation hood, Figure 3 A cross-sectional view taken along line AA of FIG. 1, and a cross-sectional view taken along line BB of FIG.

In FIG. 1, the hood part is shown, and the periphery of the rubber front plate 1a and the back plate 1b is joined by sewing or adhesive tape, and the neck portion 1c has better elasticity. It is thinner than the upper part.

The hood part 1 is attached to a viewing window 2 at the upper opening 1d of the front plate 1a, and the viewing window 2 is coated with an anti-fork to prevent blur.

A pair of lower openings 1e are formed in the lower part of the upper opening 1d so as to be located at both sides of the discharge port (one-way valve) 4, and the composite filter 3 is attached to the lower opening 1e.

The see-through window 2 is attached and bonded to a size covering the upper opening 1d of the hood part 1. The composite filter 3 is attached and adhered in a size covering both lower openings 1e of the hood part 1.

The outlet 4 is coupled to penetrate the filter 3 at the lower side of the front plate 1a of the hood 1, and inside the outlet 4, a breathable elastic close contact, such as a sponge, adhered to the nose and around the mouth. The sphere 5 is attached.

The composite filter (3) is a mesh (3a) for the protection of the filter, an electrostatic filter (3b) for filtering smoke, active carbon filter (3c) for detoxification and deodorization to remove various harmful elements, to detoxify CO The catalyst filter 3d and the reinforcing cloth 3e for reinforcement are laminated, and the peripheral part is joined by sewing or welding.

In addition, the inner surface of the front plate 1a of the hood part 1 is coated with a lining 6 so as to be in soft contact with the face part and the head, and the lining 6 is, for example, of the inner surface of the front plate 1a. It covers the surrounding area except the viewing window 2 and the composite filter 3.

It is preferable to use a nonwoven fabric for the reinforcing cloth 3e, and it is preferable to use a nonwoven fabric having good touch because it is in contact with the face portion.

The present invention as described above is carried by the user in a way that the user folds the hood and carry it in a bag, for example, when the fire meets inadvertently in the interior of the building, subway, and avoid the fire.

The fire evacuation hood of the present invention is easy to carry and wear because the front plate (1a) and the back plate (1b) is made of a rubber material, and the neck portion (1c) is formed in a thin thickness than other parts It is in close contact with the neck portion of the breathable elastic contact (5) is secured because the gap and position with the face portion is secured and airtightness is improved.

In addition, when a fire evacuation hood is worn, a visual field is secured through the see-through window 2, and smoke is generated by the electrostatic filter 3b of the composite filter 3 while externally contaminated air flows through the composite filter 3. It is filtered, various harmful elements are removed by the active carbon filter 3c, detoxification and deodorization, and CO is detoxified by the catalyst filter 3d, so that the fire can be evacuated safely while breathing the purified air. .

In addition, since the composite filter 3 is supported by the mesh 3a made of fire resistance and flame retardant material and the reinforcing cloth 3e of the nonwoven fabric, the durability is improved, and thus it can be used for a long time and can be used stably. The fog coating ensures better visibility because of the antifogging treatment.

Fire evacuation hood according to the present invention as described above is produced by the method of sewing and gluing the front and rear parts of the hood has the advantage of improving productivity, and cover the mouth and nose to the outlet of the hood to be in close contact Breathable elastic contacts, such as sponges, that can be bonded together, remove enough carbon dioxide from the breath, minimizing the size of the dead space. In addition, there is an advantage to increase the safety by anti-fog coating anti-fog coating on the see-through window, by applying a method of coating a soft lining on the face and the contact surface of the head when manufacturing the hood has the advantage of reducing discomfort during wearing. In addition, since the composite filter is formed of a mesh of fire resistance and flame retardant material, an electrostatic filter for filtering smoke, an active carbon filter for removing various harmful substances, detoxification and deodorization, and a catalytic filter for detoxifying CO, dehumidification and dedusting , Detoxification, deodorizing performance is excellent.
