Flame-resistant wick
A flame-resistant wick includes a hollow chamber and at least one capillary structure surrounding the hollow chamber. The at least one capillary structure is interlaced by a plurality of wire strands into a tubular shape. Each of the plurality of wire strands consists of a plurality of core wires made of a material having a melting point of not less than 800° C.

a hollow chamber; and
at least one capillary structure surrounding the hollow chamber and interlaced by a plurality of wire strands into a tubular shape, with each of the plurality of wire strands consisting of a plurality of core wires made of a material having a melting point of not less than 800° C.;
wherein the plurality of wire strands includes a plurality of first wire strands and a plurality of second wire strands interlaced with one another, and wherein each of the plurality of first wire strands interlaces with at least one of the plurality of second wire strands to form an acute angle, wherein the at least one capillary structure is flexible and bent into a U shape to form an igniting end and two drawing ends located opposite to the igniting end.
2. The flame-resistant wick as claimed in claim 1 , wherein at least one of the plurality of core wires is made of metals whose melting point of not less than 800° C. or carbon fiber material.
3. The flame-resistant wick as claimed in claim 2 , wherein the metals include copper or stainless steel.
4. The flame-resistant wick as claimed in claim 3 , wherein the at least one of the plurality of core wires is made of copper, and wherein the others of the plurality of core wires are made of non-copper materials.
