[0002] The existing liquid electronic cigarette uses tobacco tar as an aerosol generating atomizing agent. The tobacco tar is generally transmitted from the oil tank to the vicinity of the heating body for atomization through oil guiding cotton or a ceramic oil guiding element. The oil guiding cotton has a loose form and is not easy to control the liquid guiding flow. The oil storage capacity of the ceramic oil guiding element is weaker than that of the oil guiding cotton, and the ceramic oil guiding element is prone to insufficient oil supply. Dry burning of the oil guiding cotton or the ceramic oil guiding element produces an odor, which brings an adverse smoking experience. In addition, the flexible structure of the oil guiding cotton and the rigid structure of the ceramic oil guiding element limit the assembly mode with the heating body, which is not conducive to product design.
