Claim:
1. A vortex flame device capable of being manually ignited safely comprising: a flow guiding mechanism integrated from two half flow guiding mechanisms and with which a fuel reservoir is adapted to connect, with each half flow guiding mechanism including a wall, with the walls of the two half flow guiding mechanisms engaged together in a manner movable relative to each other, with each wall including a plurality of vanes mounted thereon, with the plurality of vanes disposed one after another along a circumference of a channel, with the two half flow guiding mechanisms jointly delimiting the channel, with two adjacent vanes of the plurality of vanes including a spiral air passage formed therebetween and in communication with the channel, with the two half flow guiding mechanisms selectively changing to a first position including a gap between free ends thereof and a second position with the free ends thereof joined; a combustion head disposed in the channel and having at least one outlet hole that fuel of the connected fuel reservoir flows through; and a hollow and transparent shield disposed above the flow guiding mechanism, with the shield delimiting a space in communication with the channel and the outlet hole; wherein the two half flow guiding mechanisms are in the first position for safe manual ignition for a user, wherein each of the two half flow guiding mechanisms includes a first base member and a second base member joined to the first base member, wherein the first base member has a first engaging end and the second base member has a second engaging end engaging with the first engaging end, wherein the first engaging end forms a plurality of first ridges each including first and second edges and an apex defined therebetween and the second engaging end forms a plurality of second ridges each including third and fourth edges and an apex defined therebetween respectively, wherein the first and second edges of one of the plurality of first ridges correspondingly face the third and fourth edges of one of the plurality of second ridges, wherein the first and second edges of the one of the plurality of first ridges have an included angle of greater than 90 degrees, and wherein the third and fourth edges of the one of the plurality of second ridges have an included angle of greater than 90 degrees.
