Patent Description:
Currently, electronic cigarette vaporizers used in the field of electronic cigarette vaporization generally have the problem of leakage of condensate. How is the condensate produced? The atomization principle of an electronic cigarette is to vaporize the smoke liquid into high-temperature atomized steam through electric heating. The high-temperature atomized steam contacts an inner wall of an airflow channel inside a cartridge when flowing in the airflow channel. Condensed liquid may be generated when the high-temperature atomized steam encounters the inner wall of the airflow channel having the normal temperature. When the condensed liquid inside the cartridge increases, it will gather together and flows out of the air inlet formed in a base of the cartridge into a battery located in a cigarette rod to damage the battery and electronic parts, or, the condensed liquid may enter the user's mouth from an air outlet when the user smokes the electronic cigarette, causing a poor user experience.

<CIT> discloses a cartridge and an electronic cigarette. The cartridge includes a liquid storage part inside of which a liquid storage cavity is formed; an air outlet channel; a porous body which comprises a main body having an atomizing surface, and two side parts arranged opposite to each other; and a container is defined and formed between the two side parts and the main part.
