Wick-burning and ventilation and flow-guide structure

A wick-burning and ventilation and flow-guide structure, comprising:

• a wick tray, which comprises a recess, the recess being provided with at least one through hole, a bottom of the recess of the wick tray being provided with a plurality of heat-dissipating fuel-dropping holes and at least one mounting hole, the wick tray being positionable on a fuel container;
• a heat isolation cover, which is in the form of a curved surface, the heat isolation cover being provided with at least one through aperture, the through aperture corresponding to the through hole, the heat isolation cover having a periphery that is formed with at least one support section corresponding to the mounting hole of the wick tray, the support section being extended to form a protrusion section that is receivable and positioned in the mounting hole, in order to connect the heat isolation cover to the wick tray in a removable manner and also to form a heat isolation space between the heat isolation cover and the wick tray, the periphery of the heat isolation cover being also formed with at least one opening part, which defines, together with a periphery of the wick tray, a ventilation heat-dissipating space;
• and
• a wick, which is made of a metallic or ceramic material, the wick being receivable in and extendible through the through aperture of the heat isolation cover and the through hole of the wick tray to be positioned, a flame-blocking heat-isolating sleeve being fit over and mounted to a surface of the wick between the heat isolation cover and the wick tray.
