Adjustable Vortex Flame Device

摘要

An adjustable vortex flame device includes a control head. The control head delimits an opening and includes a flow guiding mechanism including a plurality of vanes and a control mechanism delimiting a hole. The plurality of vanes are disposed along a circumference of the opening one after another, with two adjacent vanes including a spiral air passage formed therebetween. The hole has a diametrical size and which varies with respect to different sizes of vortex flames of the adjustable vortex flame device. The hole corresponds to and in communication with the opening. The hole is in a smaller diametrical size than the opening. A hollow and transparent shield is disposed above the control head and adjacent to the control mechanism. The shield delimits a space in communication with the hole of the control mechanism.
