DETAILED DESCRIPTION OF THE INVENTION

[0021] FIGS. 1 through 5 show a combustion device 10 in accordance with the present invention. The combustion device 10 includes a fuel reservoir 20, a wick 30, and a heat insulating and dissipating device 40.

[0022] The fuel reservoir 20 includes a container 21 and a tray 22 disposed on the container 21. The container 21 has an opening. The tray 22 covers the opening of the container 21.

[0023] The wick 30 is made of metal. The wick (30) has a top end having a substantially circular outer periphery and a bottom end having an outer periphery including two substantially parallel sides. The wick 30 is inserted through a first hole 221 of the tray 22 and into a space 211 of the container 21. The wick is clamped between two holding members of a holding device. The tray 22 defines a recess which has a base and raised lateral side walls which extend from the base upward and annularly along a perimeter of the base. The tray 22 has a brim protruding from the lateral side walls. The container 21 has a brim 212 corresponding to the brim of the tray 22. At least one fastener engages with the brims of the container 21 and the tray 22 to securely clamp the container 21 and the tray 22. The brims of the container 21 and the tray 22 include a gasket 224 disposed therebetween. With the gasket 224, the brims of the container 21 and the tray 22 join together tightly and in a sealed manner The tray 22 defines a second hole 222 communicated with the space 211 of the container 21, and the tray 22 includes a cover 223 movably connected thereto and selectively closing the second hole 222.

[0024] The cover 223 can slide with respect to the tray 22 between an open position and a closed position. When the cover 223 is moved to the open position, the hole 222 is open and allows fuel 90 to be poured into the space 211 of the container 21. Further, the cover 223, in the closed position, fully closes up and covers the hole 222.

[0025] The heat insulating and dissipating device 40 includes a heat insulating member 41 and a heat dissipating member 42 encircling the wick 30. The heat insulating member 41 is made of a non-metallic material. The heat insulating member 41 is disposed on a side of the base of the tray 22 which is opposite to a side delimiting the space 211 of the container 21. The heat insulating member 41 is disposed between the side of the tray 22 and the heat dissipating member 42. The heat insulating member 41 prevents the heat dissipating member 42 from causing the side of the tray 22 to become hot. The heat dissipating member 42 is made of a material different from that of the heat insulating member 41. The heat dissipating member 42 is made of a metallic material. The heat dissipating member 42 is disposed at a height lower than the lateral side walls of the tray 22 in order to prevent a user from accidentally touching it. The heat dissipating member 42 has a cross sectional area not smaller than a cross sectional area of the heat insulating member 41. The heat insulating member 41 and the heat dissipating member 42 are overlapped. The heat insulating member 41 and the heat dissipating member 42 respectively define an aperture through which the wick 30 inserts. The apertures of the heat insulating member 41 and the heat dissipating member 42 correspond to the first hole 221.

[0026] In view of the forgoing, the cover 223 allows a user to pour fuel 90 into the space 211 of the container 21. The cover 223 can slide with respect to the tray 22 between an open position and a closed position. When the cover 223 is moved to the open position, the hole 222 is open and allows fuel 90 to be poured into the space 211 of the container 21. Further, the use and the arrangement of the heat insulating member 41 and the heat dissipating member 42 of the heat insulating and dissipating device 40 as set forth effectively inhibits the temperature of the combustion device 10 from accumulating as the wick 30 burns, thereby preventing the user from getting burned accidentally. Furthermore, there is no need to trim the metallic wick 30 to prevent the generation of black smoke and soot.

[0027] The foregoing is merely illustrative of the principles of this invention, and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention.
