The present invention always carries a handkerchief in the bag and can be easily taken out when needed and can be easily worn, but it does not melt at high temperatures and can be easily worn by users. It relates to a fire escape mask with an air purification filter for decomposing and purifying. Conventionally, a function of dissolving and removing carbon monoxide (CO) and sulfuric acid gas (SO ₂ ) generated in a fire is enough to remove activated carbon in a nonwoven fabric or to remove dust and change generated in a fire by using a nonwoven fabric. It is not equipped to prevent the removal of toxic gas and smoke efficiently, and it is difficult to see the front due to power failure or other causes at the time of fire in the basement, as well as problems such as difficulty in breathing due to the free flow of air. When there is a case, there is a problem such that there is no suitable means for notifying the existence of a person, causing a collision with people, causing injury or falling and being unable to move anymore, resulting in an increase in casualties. The flame retardant mask defined in the recognition criteria of the flame retardant mask (enacted by FIS 004 2000. 12. 27.) is manufactured to filter out toxic gases such as carbon monoxide and smoke generated by fire. Is used for evacuation or evacuation at a place where more than 18% of the water is used, and the term "purification container" refers to the part that functions to filter out toxic gases and smoke. " Test methods and test standards for standards are established. The present invention has been made with the above-mentioned problems in the prior art in mind and the recognition criteria. Looking at the constituent means of the present invention in more detail, the transparent hood (1, Hood) manufactured to block the head portion including the face from the toxic gas and smoke in the fire is PI (Polyamide) series of thermosetting resin that does not dissolve in fire It is a transparent film that can be easily inserted into the user's head while falling down to the middle of the neck. To the edge (2) of the hood, except for the part where the user's head is inserted, the surface of the hood to be easily adhered by corona discharge, then coated with a polymer-based adhesive, and then heat-treated firmly to adhere the toxic gas and smoke inside the hood To prevent ingress. Moderately sized air purifying filter with a toxic gas decomposition catalyst for decomposing and purifying toxic gas or smoke generated in a fire and a filter for removing dust on one side of the hood where the user's nose and mouth are located when the user wears the hood (4) After the film is removed, the adhesive is adhered closely using an adhesive, and the attached filter decomposes and purifies the toxic gas or the smoke and at the same time improves the flow of the purified air to free the user's breathing as much as possible. The toxic gas and smoke purification filter 4 is designed to be introduced through the four stages of the outside air is introduced into the interior through the filter for purification and serves to decompose and filter all of the toxic gas, smoke and fine dust. In the configuration of the four-step air purification filter (Fig. 2), a non-woven filter 12 for dust filtration having a relatively large diameter is installed at a portion in contact with external air to remove a relatively large dust generated in a fire. At the stage, a catalyst 13 for removing toxic gases including a catalyst substance for decomposing toxic gases is located inside the nonwoven fabric, and at the next stage, a nonwoven filter provided with an electrostatic function to remove dust once more efficiently ( 14) is located, the last stage is a fine dust removal non-woven filter 15 for removing the fine dust is located. The toxic gas removal catalyst may be manufactured from granules having a small diameter of various metal materials according to the type of gas, and packed into a nonwoven fabric. The material of the nonwoven fabric used in the present invention is made of synthetic resin series such as polyester, polypropylene and acrylic resin. The air purifying filter structure 11 (hereinafter, used in the same term as the “air purifying filter”) is formed of a plastic box of a predetermined size to free the flow of air on the front and inside the hood. Consists of The air purifying filter (structure) inside the hood is a commercial sound generating means capable of producing a desired sound, such as a small whistle (5) fixed to a string (6) of a certain length or "I'm a person here" or "please save" ( 22) can be used to sound the presence of a person in the dark when worn. The air purification filter 4 is designed and manufactured so that it can be located at the part where the user's mouth or nose is located when worn. At the top of the hood, the luminous tape (3) is attached to a certain width and length so that the presence of a person can be easily seen in the dark, or when the mask is unfolded for wearing the mask, a commercial small liquid crystal battery is built in. At least one light emitting means (21, light emitting diode), etc., which illuminates the light in the dark by operating a switch to turn on the light is attached to the external structure of the filter to easily recognize a person and prevent a collision between people and the presence of a person. Make it easy to see whether or not. The lower part of the hood is attached in the same manner as the film used for attaching the polyamide film after inserting the general fiber string 6 to prevent external toxic gas and smoke from entering the larynx after wearing. Leave a space where you can insert a certain width of the surface to facilitate the adhesion by corona discharge, then apply a polymer-based adhesive and heat-treated firmly adhered. Both ends of the string are extended out about 10 cm in the unfolded state so that the user can easily pull when needed to prevent the inflow of toxic gas and smoke into the larynx.
