(10) FIGS. 1-4 show a flame-resistant wick 1 of a first embodiment according to the present invention. The flame-resistant wick 1 includes a hollow chamber 10 and at least one capillary structure 20.

(11) In the embodiment, the flame-resistant wick 1 may include one capillary structure 20 surrounding the hollow chamber 10 and interlaced by a plurality of wire strands into a tubular shape to cause the capillary structure 20 to be flexible.

(12) The plurality of wire strands includes a plurality of first wire strands 21 and a plurality of second wire strands 22 interlaced with one another. Each of the plurality of first wire strands 21 interlaces with at least one of the plurality of second wire strands 22 to form an acute angle θ. Thus, the plurality of first wire strands 21 and the plurality of second wire strands 22 interlace with one another to form a plurality of meshes 23, and each of the plurality of meshes 23 has the acute angle θ. Further, each of the plurality of first wire strands 21 consists of a plurality of first core wires 211, and each of the plurality of second wire strands 22 consists of a plurality of second core wires 221. Furthermore, the plurality of first and second core wires 211 and 221 are made of a material having a melting point of not less than 800° C. to provide flame-resistant purpose.

(13) Moreover, the plurality of first and second core wires 211 and 221 can be made of metals whose melting point is not less than 800° C. or carbon fiber material and have the same wire diameter. The metals may include copper or stainless steel. The melting point of copper is about 1085° C., the melting point of stainless steel is about 1400° C., and the melting point of carbon fiber material is about 1500° C., all of which are materials with a melting point of not less than 800° C., and minimize carbonization and dissipation to achieve a flame-resistant effect under the flame burning of 1000° C. In addition, according to the flame reaction, the color of the ignited flame can be adjusted by changing the material of the plurality of first and second core wires 211 and 221, for example, one of the plurality of first and second core wires 211 and 221 is made of copper, so that a green flame can be obtained after ignition.

(14) FIGS. 3 and 4 show the capillary structure 20 to be bent into a U shape to form an igniting end 24 and two drawing ends 25 located opposite to the igniting end 24 before the flame-resistant wick 1 is inserted into a fuel container S. Therefore, the flame-resistant wick 1 can be used for various fuel containers S with different heights without cutting.

(15) FIG. 5 show a flame-resistant wick 1a of a second embodiment according to the present invention, and the same numbers are used to correlate similar components of the first embodiment, but bearing a letter a. The second embodiment includes two capillary structures 20 and 20a, which are mounted around one another and extend along a central axis C of the hollow chamber 10 to maintain the shape after bending easily.

(16) FIG. 6 show a flame-resistant wick 1b of a third embodiment according to the present invention, and the same numbers are used to correlate similar components of the first embodiment, but bearing a letter b. The at least one of the plurality of first core wires 2111b and the at least one of the plurality of second core wires 2211b are made of copper. The others of the plurality of first core wires 2112b and the others of the plurality of second core wires 2212b are made of non-copper materials such as stainless steel. Thus, the number of the plurality of first and second core wires 2111b and 2211b made of copper is not greater than the number of the plurality of first and second core wires 2112b and 2212b made of non-copper materials. Therefore, the at least one of the plurality of first and second core wires 2111b and 2211b made of copper improve the thermal conductivity of the flame-resistant wick 1b to facilitate heat transfer, so that the fuel is more easily vaporized, thereby improving combustion efficiency.

(17) FIG. 7 show a flame-resistant wick 1c of a fourth embodiment according to the present invention, and the same numbers are used to correlate similar components of the first embodiment, but bearing a letter c. Each of the plurality of first and second core wires 211c and 221c has a different wire diameter to the others to change the size of the meshes 23c to increase the capillary action of the flame-resistant wick 1c to improve the combustion efficiency.

(18) FIG. 8 show a flame-resistant wick 1d of a fifth embodiment according to the present invention, and the same numbers are used to correlate similar components of the first embodiment, but bearing a letter d. The plurality of first and second core wires 211d and 221d are made of carbon fiber material. The denier count of the carbon fiber material can be between 150 to 300 denier, thereby improving the structural strength and capillary action of the flame resistant wick 1d to improve the combustion efficiency.
