Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used for evacuation from fires or fires caused by earthquakes. It protects the respiratory tract, visual, auditory, olfactory, neurological tract, etc. during emergency evacuation during a fire, as it protects the respiratory tract from toxic gases generated during a fire, and maintains a sufficient field of vision. , concerning the improvement of the respiratory part of a smoke and gas mask that allows people to move safely and quickly to a designated evacuation site without affecting the head, where the most important sensory organs are concentrated in human behavior. be.

Conventionally, there are many types of smoke masks of this kind, but when worn on the head, they have a complicated structure, so in an emergency, especially in the case of a fire, people usually have to act calmly and take measures out of fear. Since they are often difficult to remove, those that require time and effort to wear are unsuitable.

In addition, even if it is easy to put on, a smoke mask that does not have an insulating effect and is made of materials and structures that are weak against heat can catch fire when acting in high heat, such as a fire. In some cases, people may suffer burns or even die from wearing a mask.

In addition, even if smoke masks are made of heat-resistant materials, if they are constructed solely for the purpose of preventing fires, they may cause breathing difficulties because no measures have been taken to prevent toxic gases associated with fires. They may die, or even if they are rescued, they may suffer from gas poisoning and become paralyzed.

As an invention to solve these drawbacks, a bag that can cover the entire head and near the neck has a see-through part in the part facing the eyes, and contains a smoke absorbent in the part facing the mouth. There are smoke and gas masks that are equipped with air intake and exhaust parts, and the exterior parts are all made of flame-retardant materials, but they protect the head from fire and ensure the minimum necessary breathing conditions before evacuating. However, in the event of an emergency evacuation such as a fire, the respiratory system is disturbed due to stress, and even if the smoke mask itself has a strong ability to absorb and remove toxic gases and smoke, In the same invention, the function of sucking air from which external smoke or toxic gases have been adsorbed and removed requires an unstable operation of attaching the mouth directly to the intake/exhaust member and sucking/exhausting it, and the intake air also has a multilayer structure. Because the mask has to pass through the intake and exhaust members, it requires a fairly strong intake and exhaust force. The disadvantage is that it is not possible to take calm evacuation actions.

In addition, with conventional smoke and gas masks, even if purified air is inhaled through the intake and exhaust members, most of the exhaust air is exhausted into the mask body with the intake and exhaust members configured as described above. However, there are disadvantages in that the transparent part becomes cloudy or carbon monoxide fills the mask body.

The present invention has the advantage of providing sufficient visibility and adsorbing and removing effects of toxic gases, smoke, etc., which the head cloth has to protect the head and face, and furthermore, it eliminates the instability of having to inhale directly from the mouth contact point of the respiratory member. We have improved the respiratory system parts so that you can breathe in a stable state at all times, and the air intake and exhaust parts, which are made of multiple layers containing toxic gas adsorbents, can smoothly breathe in and out. The purpose is to

The structure of the present invention is that in a bag that can cover the entire head and the vicinity of the neck, the other parts except for the part facing the eyes and the part facing the mouth are made of flame-retardant polyvinyl chloride sheet. The sheet is made of a polymer sheet of fibers and a heat insulating non-woven fabric, and the flame-retardant polyvinyl chloride sheet and the flame-retardant fiber polymer sheet and the heat insulating non-woven fabric form a space without adhesion and face the eyes. A flame-retardant transparent vinyl chloride sheet is used for the transparent part attached to the part, and an intake/exhaust member is attached to the part that corresponds to the mouth. A breathable bag coated with a heat-insulating non-woven fabric is placed in the center, and ventilation holes are sequentially punched from the bag toward the eye area. A polymer, a space formed with the polymer and a heat insulating nonwoven fabric are located, and from the inside outward from the bag, flame retardant fibers, flame retardant fibers formed by perforating ventilation holes, and flame retardant fibers are arranged in order from the inside. This relates to a smoke and gas mask, characterized in that a polymer with a flammable polyvinyl chloride sheet is located thereon, and a mouthpiece member that can be inserted into the lips is protruded from the insulating nonwoven fabric in the sun-exposed part. , this will be explained based on the embodiment shown in the drawings.

Reference numeral 1 denotes a smoke-proof and gas-proof mask of the present invention, which in this embodiment is a bag made of a flame-retardant sheet, and is large enough to cover the entire head and the vicinity of the neck.

Reference numeral 2 denotes a transparent part, which is made of a flame-retardant transparent vinyl chloride sheet in this embodiment, but any transparent and flame-retardant material may be used.

In FIG. 2, reference numeral 3 denotes an air intake/exhaust member, which is shaped like a bag and has a poison absorbent 4 such as activated carbon, zeolite, or dawsonite in its core.

This poison absorbent 4 is housed in a breathable heat insulating nonwoven fabric 5.

This activated carbon, zeolite, and dawsonite are heat-insulating nonwoven fabrics 5
The zeolite and dawsonite may be individually encapsulated and formed into three layers, a combination of zeolite and dawsonite, or a mixture of each.

Furthermore, in this embodiment, a flame-retardant polyvinyl chloride sheet 6 and a flame-retardant fiber 7 are sequentially placed in the direction of the face with the poison absorbent 4 in the center, without being in close contact with the heat-insulating nonwoven fabric 5, leaving a gap. A sheet made of a polymer with a plurality of ventilation holes 8 perforated at appropriate locations is placed, and a heat insulating nonwoven fabric 9 such as breathable spunlace is placed at appropriate intervals without being adhered to the sheet. To position.

In addition, in the outward direction, with the poison absorbent 4 in the center, breathable flame-retardant fibers 10 such as polyfural are placed with appropriate voids. A sheet made of a polymer of flame fibers 11 and a flame-retardant polyvinyl chloride sheet 12 and having a plurality of ventilation holes 13 perforated therein is located.

Reference numeral 14 denotes a mouthpiece-like mouth abutting part, which the user uses by holding it in his/her lips 15, and is attached to the insulating nonwoven fabric 9 of the face-facing part, with a constant through hole in the middle part. Separator 16 for preventing adhesion as much as possible
is intervening.

According to the present invention, clean air is sucked in or exhausted from the mouth contact portion 14 directly through the intake/exhaust member 3, but the mouth is not brought into direct contact with the intake/exhaust member. Unlike the case where the patient breathes with the mouthpiece-shaped mouth contact part 15, stable inhalation and exhaustion can be performed.

Therefore, when evacuating in situations such as fires or earthquakes where the spirits are high and the respiratory system is disturbed, the mouthpiece can reliably suck clean air powerfully for a short period of time. It has an excellent effect that is completely different from conventional smoke and gas masks in case of emergency evacuation.
