Abstract
A hot air blower includes a shell including a fan mechanism, a combustion device, a vane mechanism, and a flame protector disposed therein. The vane mechanism includes a clipping seat and a plurality of guiding vanes extended thereon. The plurality of guiding vanes extend obliquely and prevents the air passing through the vane mechanism from generating turbulence. The clipping seat and the flame protector form a half-closed combustion chamber therebetween. Heat in the half-closed combustion chamber causes a thermal expansion of the air and, thereby increasing a speed and a volume of the air passing the guiding vanes of the vane mechanism. The heated air is discharged from an external flow tube and which controls a heating range of an area of the hot air blower.
Claims15
A hot air blower comprising:
- a shell;
- a fuel canister, a fan mechanism, a combustion device, a vane mechanism, and a flame protector disposed within the shell, with the fan mechanism blowing air, with the combustion device including a burning end, with the vane mechanism disposed in a position locating the combustion device between the fan mechanism and the vane mechanism, with the vane mechanism including a clipping seat and a plurality of guiding vanes, with the plurality of guiding vanes extending axially and obliquely from the clipping seat, with the axially and obliquely disposed plurality of guiding vanes preventing the air passing through the vane mechanism from generating turbulence to achieve a flow-regulating effect;
- with the flame protector and the burning end axially disposed within the vane mechanism, with the flame protector circumferentially surrounding and hooding the burning end of the combustion device, with the flame protector including a lateral wall including a plurality of vents, with the air passing the vane mechanism expelled out of the plurality of vents, with the clipping seat and the flame protector connected together and forming a half-closed combustion chamber therebetween, with heat in the half-closed combustion chamber causing a thermal expansion of the air and thereby increasing a speed and a volume of the air passing the plurality of guiding vanes of the vane mechanism;
- and
- an external flow tube extended out of the shell, with the heated air discharged from the external flow tube which controls a heating range of an area.

- with the flame protector disposed within the vane mechanism and hooding the burning end of the combustion device, with the flame protector including a lateral wall including a plurality of vents, with the air passing the vane mechanism expelled out of the plurality of vents, with the clipping seat and the flame protector forming a half-closed combustion chamber therebetween, with heat in the half-closed combustion chamber causing a thermal expansion of the air and thereby increasing a speed and a volume of the air passing the plurality of guiding vanes of the vane mechanism;
- and
- an external flow tube extended out of the shell, with the heated air discharged from the external flow tube which controls a heating range of an area.
