Abstract
An adjustable vortex flame device includes a control head delimiting a through hole with an opening and including a flow guiding mechanism including a plurality of vanes and a flow control head inserting in the through hole. The flow control head includes a first member and a second member detachably engaging with each other and delimiting a first chamber and a second chamber connecting to each other. The two channels extend in the first member and to an outer periphery of the flow control head and connect to the first chamber. The flow control head has two flow outlets defined at distal ends of the two channels and a flow inlet defined at a distal end of the second chamber. A hollow and transparent shield is disposed above the control head and delimits a space fluidly connecting to the through hole.
