Abstract
A gas hot air gun includes a main body, an air blower, an ignition device, a nozzle and a switch set. The main body includes a barrel, a handle, a heating chamber and a mixing chamber on the inner front of the barrel. A battery set and a gas can are inside the handle. One end of the nozzle is connected to the gas can. The switch set includes a power switch and an ignition switch. Users press the power switch and have gas spray out from the nozzle into the heating chamber to generate heat. The blower sends out hot air in the heating chamber out of the main body. A metal slice to regulate the direction of air and a catalyst to avoid flames from coming out of the nozzle area are inside the heating chamber.

A gas hot air gun comprising:
- 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 air blower installed internally on an end of said barrel and powered by the battery set;
- an ignition device installed inside said barrel;
- a nozzle installed inside said main body, wherein one end of said nozzle is connected to the gas can to spray gas;
- and
- a switch set installed inside said main body, said switch set comprises a power switch and an ignition switch, wherein users press said power switch and have gas spray out from said nozzle into said mixing chamber to mix with air which then is sent to said heating chamber, said ignition switch has said ignition device ignite the mixed gas and air and generate a heat source, wherein said blower blows hot air inside said heating chamber out of the barrel, wherein a first and a second container are installed in said handle to hold the battery set in said first container and the gas can in said second container, wherein a movable cover is on a bottom of said handle to cover said first and said second container.
A gas hot air gun comprising:
