Claim Text:
1. An adjustable vortex flame comprising: a control head delimiting an opening, with the opening having a diametrical size, wherein the control head includes a base having an inner periphery thereof delimiting the opening, wherein the base 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, wherein 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 one of the plurality of first ridges have an included angle of greater than 90 degrees, wherein the third and fourth edges of one of the plurality of second ridges have an included angle of greater than 90 degrees, with the control head including a flow guiding mechanism including a plurality of vanes, with the plurality of vanes disposed along a circumference of the opening one after another, with two adjacent vanes including a spiral air passage formed therebetween, with the control head including a control mechanism delimiting a hole, with the hole having a diametrical size and which varies with respect to different sizes of vortex flames, with the hole corresponding to and in communication with the opening, with the hole in a smaller diametrical size than the opening, wherein the flow guiding and control mechanisms are mounted on the base; and a hollow and transparent shield disposed above the control head and adjacent to the control mechanism, with the shield delimiting a space in communication with the hole of the control mechanism.
