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.
