When the height of the bump 2 is excessively low, it is inconvenient to form a significant end surface on the bump 2, which brings an obstacle to the arrangement of the heating body 3. When the height of the bump 2 is excessively high, the bump occupies an excessively large area of the electronic cigarette vaporization core 100 and increases a penetration path of e-liquid of the electronic cigarette, which reduces the vaporization efficiency of the electronic cigarette vaporization core 100.

The arrangement of the bump 2 can avoid setting an excessively large vaporization surface area. When the vaporization surface formed on the bump 2 is fully used, full utilization of the vaporization surface can be ensured through heating of the heating body, and on the basis of improving a heating speed of the heating body 3, utilization efficiency of the vaporization surface is ensured. When the contour of the heating body 3 matches the edge of the bump 2, the heating body 3 may heat a middle and a side of the bump 2 uniformly when generating heat, to ensure an effective vaporization area of the vaporization surface, improve heating efficiency of the heating body 3 and an amount of vaporization of the electronic cigarette vaporization core 100, and ensure a vaporization effect of the electronic cigarette.

A vaporization chamber 106 is formed between the vaporization surface and the lower support 104, and an air vent in communication with the air inlet hole 1051 is provided on the lower support 104.
Specifically, when the electronic cigarette vaporization assembly works, e-liquid flowing out from the e-liquid storage tank 102 is guided to the liquid absorbing end of the porous body 1 through the e-liquid guiding hole 1032, then is absorbed through capillary action of the porous body 1 to the heating body 3 on the vaporization end of the porous body 1, and then is vaporized through heating of the heating body 3. In this case, under an inhalation action of the air outlet channel 1011, a user drives air in the air inlet hole 1051 to enter the vaporization chamber 106, and the air carrying an aerosol in the vaporization chamber 106 is guided to the air outlet channel 1011. Because the e-liquid is continuously absorbed by the porous body 1 and supplemented to the heating body 3, a negative pressure is formed in the e-liquid storage tank 102, and under an action of the negative pressure, external air may pass through the vaporization chamber 106 and the electronic cigarette vaporization core 100 and then enter the e-liquid guiding hole 1032 and the e-liquid storage tank 102, to form a balance air pressure, thereby ensuring that the e-liquid can be smoothly guided to the porous body 1.

In this embodiment, the electronic cigarette may not include the lower support 104, and the upper support 103 is engaged with the lower cover 105 to fix the electronic cigarette vaporization core 100.
Optionally, the electronic cigarette includes:
Specifically, the electronic cigarette vaporization assembly has a simple structure, and a component in the housing occupies less space, so that a space volume inside the electronic cigarette that can be used to form a vaporization cavity is increased. Compared with a related art, the electronic cigarette vaporization assembly in the solution adopts only a form of matching between the housing and the lower base to limit the structures such as the vaporization core, thereby simplifying the internal structure of the electronic cigarette vaporization assembly and leaving more space for the vaporization core and the vaporization cavity.
