Abstract
A gas hot air gun includes a main body, an ignition device, a switch set and a safety switch. The main body includes a blower, a nozzle, a barrel and a handle. A heating chamber and a mixing chamber are on the inner front of the barrel. A gas can is inside the handle. One end of the nozzle is connected to the gas can. The switch set includes a power switch, with the safety switch closing power of the battery set or gas flow under some pre-set conditions. Users press the power switch and have gas spray out from the nozzle into the heating chamber to generate heat. The blower sends hot air in the heating chamber out of the main body. A metal slice, regulating the direction of air, and a catalyst, for avoiding flame extending out of the nozzle area, are inside the heating chamber.
Claims22
A gas hot air gun comprising:
- a blower;
- a nozzle;
- a main body including a barrel and a handle, with a heating chamber and a mixing chamber in said barrel, and a battery set and a gas can inside said handle, wherein the gas can contains burnable fluid;
- an ignition device installed inside said barrel;
- and
- a switch set installed inside said main body, said switch set including a power switch and an ignition switch, when said power switch is pressed, gas is sprayed out from said nozzle into said mixing chamber to mix with air and sent to said heating chamber, wherein said ignition switch has said ignition device ignite the mixed gas and air and generate heat, said blower blows hot air inside said heating chamber out, wherein a metal slice is inside said heating chamber, with the metal slice having a good heat exchange rate and heat conductivity to be heated up and cooled down rapidly, said metal slice also has air flow direction regulation effect, with the metal slice including an axially extending burning chamber, with the metal slice further including a plurality of lobes, with the lobes and the main body defining a plurality of passages radially spaced from and circumferentially spaced around the burning chamber.
