The present invention is not bulky and convenient to be carried by the general public and can be easily worn out when needed. The present invention relates to a multifunctional mask equipped with a purification filter for decomposing and purifying dust. Conventionally, carbon monoxide (CO) and sulfurous acid gas (SO ₂ ), which are frequently generated in a fire, are removed to remove dust and change generated in a fire by using activated carbon inside a nonwoven fabric or by using a nonwoven fabric and present in a general atmosphere. It does not have the means to efficiently remove and remove various kinds of harmful gases and fine dust (ozone, carbon dioxide, sulfur dioxide, fine dust, etc.) and toxic gases generated in industrial sites. There is also a problem, and conventionally there is no separate structure for sealing the toxic gas and dust into the user's nose and mouth so that the toxic gas or dust is somewhat introduced into the hood, there is a problem in reliability and stability, Easily discharge the air sucked into the structure of the air purification filter There is a problem that the means are not provided, resulting in difficulty in breathing due to lack of oxygen and disturbance of air flow, so that they cannot be worn for a long time. The present invention focuses on solving the above problems of the prior art. Looking at the constituent means of the present invention in more detail, the transparent hood (1, Hood) that covers the entire face is a transparent film of PI (Polyamide) series of thermosetting resins insoluble in fire, rectangular or ordinary users easy to store and easy to wear It is designed and manufactured in size and shape that can easily block various kinds of gases and dust that are harmful to human body. The hood is surface treated to be easily adhered to the edge 2 except for the part where the user's head is inserted, and then coated with a polymer-based adhesive, followed by heat treatment to firmly adhere the harmful gas and smoke to the inside of the hood. To prevent ingress. One side of the hood where the nose and mouth are located when the user wears the hood has a toxic gas decomposition catalyst and a dust removal filter that decomposes and purifies toxic gas generated in a fire, harmful gases and dust generated in the air or industrial sites. The built-in air purifying filter 4 of a suitable size is closely attached using an adhesive agent. The inner hood film to which the air purifying filter is attached is removed to free the flow of air into or out of the air purifying filter. The air purifying filter which decomposes the harmful gas attached to the hood and filters the dust decomposes various kinds of harmful gases of the human body, purifies the dust and at the same time improves the flow of the purified air to free the user's breath as much as possible. The inside of the filter for air purification is made of a silicon (6) or a soft rubber material harmless to the human body is attached to the structure (6) for sealing so that no harmful gas and dust into the user's nose and mouth. The left and right sides of the structure is attached to the structure around the nose and mouth to prevent the influx of harmful gas and dust is attached to the strap 8, the outside of the structure where the nose is located by the bending of the nose (height) To prevent the ingress of toxic gas and dust, a thin, small plate of aluminum (7) is attached. The strap 8 is formed in a form that can be hooked to the ear or a hook or fixed to the head. At the edge of the filter structure for air purification is attached a valve to free the intake of air during the separate air discharge. The air purification filter for the removal of harmful gases and dust is introduced into the interior through the filter for purification of the outside air, all four stages are designed to decompose and filter all kinds of harmful gases, dust, smoke and fine dust Play a role. In the construction of the four-stage air purification filter (FIG. 2), a non-woven filter for dust filtration having a relatively large diameter is installed at a portion contacting the outside air to remove relatively large dusts first, and then a toxic gas is disposed at the next stage. A catalyst for removing toxic gases including a decomposing catalyst material is located inside the nonwoven fabric, and at the next stage, a nonwoven filter provided with an electrostatic function is removed to remove dust more efficiently. There is a non-woven filter for removing fine dust to remove. The toxic gas removal catalyst is made of granules having a small diameter as a material containing various kinds of metal ions according to the type of gas and packed in a nonwoven fabric and embedded in a filter. 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 (hereinafter referred to as the term "air purifying filter") is composed of a plastic box of a predetermined size and is formed in a form of freeing the flow of air on the front surface and the inside of the hood. A separate space 16 is installed on the left and right sides or the slopes of the air purifying filter structure to install the valve so that the valve 24 is opened when the users discharge the air, and the closed state is normally or at the time of inhaling the air. It is designed to maintain the user's breathing more smoothly. The space 16 formed on one side of the air purification filter structure and installed with a valve may be installed on one side of the slopes of the air purification filter structure or may be formed on both sides or both sides of the air purification filter structure. In consideration, some of the formed space may be blocked, and a valve may be installed only in a part of the space. The air purifying filter (structure) inside the hood is equipped with a commercially available small sound generating means capable of producing a desired sound, such as a small whistle (25) fixed to a string of a certain length or “I'm a person here” or “please save”. It can be used to generate sounds in the dark or when needed to signal the presence or danger of a person. At the top of the hood, a colored luminous tape (3) is attached with a certain width and length to easily recognize the presence of a person in the dark, or a power supply (with a built-in small battery) and a switch are installed if necessary. Alternatively, at least one light emitting device (light emitting diode, etc.) capable of illuminating the light at a necessary place may be attached to at least one external structure of the filter to easily recognize each other, to inform a danger, or to request a structure. The lower part of the hood is inserted in the same manner as the film used to attach the polyamide film after inserting the general fiber string 5 to prevent external toxic gas and dust from entering the larynx after wearing. After leaving a space to move the surface to be easily adhered to a certain width by corona discharge, apply a polymer-based adhesive, and then heat-treated firmly. Both ends of the string are stretched out about 10 cm in the unfolded state so that the user can pull it out when necessary to prevent the introduction of various gases and dusts harmful to the human body into the larynx.
