The battery module 100 supplies power to the control driving module 200 and the heating module 300. The control driving module 200 controls the heating module 300 to heat the air entering the heating module 300, and the fuming medium is baked by the hot air, so that the fuming medium is atomized into smoke for a user to suck. Wherein, the smoking medium can be tobacco, smoke cartridge, tobacco tar and cigarette.

Specifically, please refer to fig. 2 to 4. The heating module 300 of the present embodiment includes a base 10, a sleeve 20, a first heating assembly 30, a separation tube 40, a connection member 50, and a second heating assembly 60. In addition, the e-smoking article 1000 further includes a housing 70 and a cover 80.

The sleeve 20 is fixedly arranged on the base 10. The sleeve 20 comprises a first accommodating cavity 20a and a second accommodating cavity 20b, wherein the first accommodating cavity 20a is communicated with the second accommodating cavity 20b, and the second accommodating cavity 20b is positioned at one end of the first accommodating cavity 20a far away from the base 10.

The first heating element 30 is fixedly disposed in the first accommodating chamber 20a, and the first heating element 30 is fixedly connected to the base 10.

The separation tube 40 is disposed on the first heating assembly 30 and is located in the second receiving chamber 20 b.

The connecting member 50 is fixedly provided to the separation tube 40. The connecting member 50 is fixedly disposed in the second receiving chamber 20 b.

The second heating assembly 60 is disposed on the separation tube 40. Specifically, the second heating assembly 60 is detachably disposed on the separation tube 40 through the connection member 50; that is, the connection member 50 connects the separation tube 40 and the second heating assembly 60, respectively. The second heating element 60 is located in the second accommodating cavity 20b, and optionally, the second heating element 60 may be located completely in the second accommodating cavity 20b, or may be located partially in the second accommodating cavity 20b, which is not limited in this embodiment.

For example, when the electronic smoking set 1000 is in the preheating stage, the first heating element 30 heats the air entering the first heating element 30 to form hot air, the hot air rises into the lower portion of the placing chamber M and gradually diffuses to the upper portion of the placing chamber M, but the diffusion of the hot air requires a certain time, and the temperature of the air in the upper portion of the placing chamber M is always lower than that of the air in the lower portion of the placing chamber M because the first heating element 30 is close to the lower portion of the placing chamber M. This causes the overall temperature of the air in the placing chamber M to be uneven.

And the second heating unit 60 is disposed at the upper portion of the placing chamber M through the partition pipe 40, and at this time, when the first heating unit 30 starts to heat the air, the second heating unit 60 also starts to heat the air at the upper portion of the placing chamber M at the same time. That is, the first heating assembly 30 diffuses the hot air into the lower portion of the placing chamber M and continues to diffuse toward the upper portion of the placing chamber M; the second heating unit 30 heats air at the upper portion of the placing chamber M into hot air, and the hot air is gradually diffused toward the lower portion of the placing chamber M.
