[0030] Combined Figure 1 And Figure 2As shown, the side of the oil cup 4 facing the air inlet hole 30 is beveled, and the angle of the bevel is α, which is 35°±0.5° in this embodiment; the plane on which the bottom of the planar ceramic atomization core 7 is located is a ceramic atomization plane. The inside of the electronic cigarette body is provided with an air channel, and the air channel is combined with Figure 1 and Figure 3 As shown, the initial section of the air channel is the opening 20 of the bottom cover of the electronic cigarette body, and the inner side wall is provided with an air inlet hole 30 in communication with the opening 20, and the air inlet hole 30 is combined with Figure 1 The dashed arrow is a schematic diagram of the air path, and it can be seen that the airflow passes through the air inlet hole 30 from bottom to top and then flows horizontally through the ceramic atomization plane. The air inlet hole 30 is located on the side of the ceramic atomization core, and the distance between the air inlet hole 30 and the ceramic atomization plane is h, which is 0.35 mm in this embodiment. The airflow enters the oil cup 4 from the side to avoid the condensate or tobacco tar flowing downward from blocking the air inlet hole 30. The smoke generated by atomization flows out through the air channel of the oil cup 4 to the mouthpiece 2. Specifically, after the airflow enters the air inlet hole 30 from the bottom opening 20 from bottom to top, the airflow enters the oil cup 4 from the side of the oil cup 4 and impacts the bevel transition of the oil cup 4.

[0032] As shown, Figures 4-5 The inside of the ceramic support 8 is provided with a plurality of cylindrical protrusions 10, and the spacing between adjacent protrusions 10 is 0.5-3 mm. The design of the protrusions 10 increases the surface area inside the ceramic support 8, i.e., increases the surface area of the atomization chamber, which can effectively hold the condensate and tobacco tar generated inside the atomization chamber, reduce the accumulation of condensate and tobacco tar, and avoid blocking the air inlet hole 30 to cause changes in suction resistance or no smoke.
