[Detailed Description of the Invention] (Technical Field) This invention relates to a gas mask for protecting the entire human body from carbon monoxide (hereinafter referred to as CO) contained in gas (Prior art). Fires and explosions often result in a high concentration of Co, and in order to protect human life from this atmosphere, metal oxide catalysts, such as manganese oxide and copper oxide, have traditionally been used. Phobcalide (main component MnO2-0uO) is known.

However, this fobcalide catalyst can be converted from CO to 00 at room temperature.
.. However, since the arranging ability is reduced by moisture, it is also possible to use noble metal catalysts alone or in combination with hobkasite, and the oxidation of 00 itself has become satisfactory.

('F4 Issues to be resolved) However, considering the reaction form, co+-! −o2−aot+Q (Q”=94.1Ka

Is this air that has a higher temperature than K? Is it hot when humans smoke it? Are you wearing a gas mask because you can't stand the high fever? Accidents such as removal of the plug and eventual CO poisoning have occurred.

The main thing about all types of gas masks is that if you tighten the straps for wearing on your head properly, the mask will cover your face.
The air 4 containing 002 is oxidized by the oxidation catalyst 2 to become CO2, and this 00. When reacting with fc, e heats up, that is, is it an endothermic reaction? 9. The substance 3 absorbs heat and is lowered in temperature to become fc air 5. This will be supplied to the human mouth and nose.

It is an endothermic reaction that occurs smoothly in the vicinity, and the high heat ζ generated during the production of CO□ is consumed, making the intake air completely low temperature and rendering it harmless.

(Effects of the Invention) As described above, the present invention uses an oxidation catalyst VC process to convert 00 to harmless CO1 in the air and convert it to carbonate by a substance that subsequently undergoes an endothermic reaction.
Since there is no CO in the intake air, and the air is low temperature and has a large oxygen basin, it is possible to take in air, so there is enough time to escape from the danger area.
