Burning wick structure

Abstract

A burning wick structure includes an upper half portion and a lower half portion. The outer diameter of the upper half portion is larger than that of the lower half portion. The bottom surface of the lower half portion is provided with an insertion hole for being inserted by an end of a cotton thread. The top portion of the insertion hole is further provided with an evaporating region. A porous region having a larger thickness is formed between the evaporating region and the top portion of the upper half portion. The porous region is formed with at least one ventilating region having a smaller thickness.
