Abstract
A vortex flame device includes a flow guiding mechanism integrated from two half flow guiding mechanisms and with which a fuel reservoir is adapted to connect. Each half flow guiding mechanism includes a wall. The walls are engaged together in a manner movable relative to each other, and each includes a plurality of vanes mounted thereon. Two adjacent vanes include a spiral air passage formed therebetween and in communication with the channel. The two half flow guiding mechanisms selectively change to a first position including a gap between free ends thereof and a second position with the free ends thereof joined. Further, a combustion head is disposed in the channel and has at least one outlet hole that fuel of the connected fuel reservoir flows through. Further, a shield is disposed above the flow guiding mechanism.
