Abstract (en)
The present disclosure relates to an electronic vaporization device and a vaporizer thereof. The vaporizer includes a liquid storage housing (10) having a liquid storage cavity (110) formed therein and a heating base (52) arranged in the liquid storage housing. The outer surface of the heating base is provided with a vent channel (522), a liquid absorbing groove opening (523), a liquid storage groove (524) and a vent entrance (525). One end of the vent channel is communicated with the liquid storage cavity, and the other end of the vent channel is respectively communicated with the liquid absorbing groove opening and the vent entrance. The liquid storage groove is communicated with the liquid absorbing groove opening to absorb liquid substrate to the liquid storage groove by a capillary force. The vent channel is provided with the vent entrance and the liquid absorbing groove opening, the vent entrance is configured to introduce an external air, and the liquid absorbing groove opening is configured to absorb the liquid substrate into the liquid storage groove through the capillary force, thereby isolating ventilation from liquid storage and preventing the liquid substrate from blocking the vent channel.
