In other embodiments, the atomizing assembly 30 may be disposed laterally within the central passage 201. The heating element is wound on the periphery of the liquid absorbing element in a spiral mode by a heating wire. Two ends of the liquid absorbing piece are respectively matched in the two opposite liquid guide holes. Both ends of the heating wire extend outward to connect the positive and negative electrodes of the power supply device 200, respectively.

The atomization device 100 may further include a silicone sleeve 60 disposed between the second end of the air duct 40 and the atomization seat 20, which may prevent the air duct 40 from directly contacting the atomization seat 20, and further prevent the air duct 40 or the atomization seat 20 from being worn when the air duct 40 rotates.

In the present embodiment, as shown in fig. 5-6, the air passage valve includes a first valve plate 71 radially disposed in the second end of the air guide tube 40, and a second valve plate 72 enclosed on the end surface of the atomizing base 20 facing the air guide tube 40. The first valve plate 71 is provided with a first plate hole 710, so that the air passage of the air duct 40 can be communicated with the central channel 201 of the atomizing base 20 through the first plate hole 710; the second plate hole 720 is formed in the second valve plate 72, so that the central passage 201 of the atomizing base 20 can communicate with the air passage of the air duct 40 through the second plate hole 720.

With reference to fig. 2 and 3, and fig. 5 and 6, when the air passage valve is in the open state, the first plate hole 710 and the second plate hole 720 are oppositely communicated, so as to communicate the air passage of the air duct 40 with the central passage 201 of the atomizing base 20.

The leak-proof plug 74 is arranged on the side of the leak-proof cotton 73 away from the atomizing assembly 30, and also seals off the port of the atomizing base 20 away from the air duct 40. Meanwhile, a channel hole 75 is formed between one side of the leakage preventing plug 74 and the side wall of the atomizing base 20, the channel hole 75 communicates with a central channel 201 of the atomizing base 20, and the central channel 201 communicates with the outer space of the atomizing base 20 through the channel hole 75. Two ends of the heating element penetrate through the anti-leakage cotton 73 and the anti-leakage plug 74 to extend out of the atomizing base 20 to be respectively connected with the positive electrode and the negative electrode of the power supply device 200.
