Rate, so the air can take away the heat of the metal foil Π 3 to form hot air, which is carried to the catalyst 1 14 , and the catalyst 1 14 can still contain a small amount of gas in the hot air. Complete combustion, reducing the production of carbon monoxide, this is secondary combustion, because the hot air passes through the second combustion, it can raise the temperature of the hot air again, and obtain a safe and high temperature gas, in addition, the catalyst 1 1 4 It can avoid the occurrence of open flame, and effectively prevent the flame that is still burning in the metal foil 1 1 3 from being discharged out of the air outlet 14 . The mixed gas requires a good mixing ratio of the wife to obtain a good combustion rate in the combustion chamber 1 15 , so when the oxygen content in the mixed gas is too low, the inhalation around the combustion chamber 1 15 The port 11 7 can replenish air in a timely manner, which utilizes the principle that the neck of the mixing chamber 11 2 is tapered, so that air can be sucked from the suction port 11 7 to be mixed with the gas, and enter the combustion chamber 1 1 5

1279199 V. Description of the invention (7) = ^ 疋 combustion, in addition, the gas can be controlled via the regulating valve 5 4 = 塁 'Because the foil 113 in the heating chamber 111 has good heat conduction $ can be ignited The combustion chamber 11 5 rapidly raises the temperature, and when the fire is heated to 111, if the combustion is incomplete, a poisonous carbon monoxide is generated, which is harmful to the human body. In order to completely burn the flame, the catalyst 1 14 can achieve this purpose. 'The catalyst 1 14 can be chemically anti-aspirated with the gas in the combustion, and the latter gas is converted into non-toxic carbon dioxide to form a safety: gas, electric mountain and catalyst Π4 can avoid the occurrence of open flame, effectively prevent the flame /3⁄4 leaking out of the air outlet 1 4 outside. Source threshold ί ΐ When the following conditions are used, the function of the safety switcher 60 is exerted. The temperature sensor 23 on the part 11 senses the temperature 21 stop i i i ' ' ” ” ” ” ” ” ” safe safety switch 6 ° interrupt all signals, so that the motor stops running, the magnetic lever 52 is detached and stopped = know 23 if the temperature is detected If the height is high, then the magnetic technology #52 is out of the stop air supply, and the motor 21 is lowered in temperature for a certain period of time and then stops running; when the power switch 51 is turned off, the device 23 still measures the high temperature, and the safety switch 6 causes the nozzle 4 to be closed. 〇 Stop the mouth: 2 The blower 20 is energized, so that the blower 20 operates to maintain the air supply to lower the temperature of the twisting 1. Since the foil Π3 has a good thermal conductivity: it can quickly absorb the cold air and cool down to help the heating chamber π丨Cooling, when the temperature sensor 230 senses that the heating chamber 111 reaches a certain cooling temperature, the blower 20 is powered off; this design makes the invention more portable and less prone to burns.
