[0036] In this embodiment, when the user starts to inhale, the medicine liquid or aerosol medium in the liquid storage tank 11 flows to the atomizer 4 through the liquid inlet hole 21, the liquid guide member 3, and the through hole in sequence. At the same time, the atomizer 4 in contact with the liquid guide member 3 vibrates at a high frequency and heats up, and the medicine liquid or aerosol medium is atomized to produce aerosol, which is discharged to the air outlet 14 through the first channel 51.
[0037] In this embodiment, a first seal 5 is provided to prevent water vapor from entering the atomizer 10 from the air outlet 14 , and the first seal 5 is provided between the housing 1 and the atomizer sheet 4 to fix the atomizer sheet 4 and prevent the atomizer sheet 4 from displacement.
[0038] like Figures 2 to 4 As shown, further, the bracket 2 includes a accommodating cylinder 22 and a support frame 23 arranged on the outer wall of the accommodating cylinder 22, the accommodating cylinder 22 is arranged in the liquid storage tank 11, the liquid inlet hole 21 is arranged on the wall of the accommodating cylinder 22, and the liquid guiding member 3 is installed in the accommodating cylinder 22; the support frame 23 is connected to the liquid storage tank 11 and seals the liquid storage tank 11, and the atomizing sheet 4 is arranged on the support frame 23.

[0054] Furthermore, at least one electrode group is provided on the housing 1 , and the atomizing sheet 4 is electrically connected to the electrode nail 9 .
[0055] Furthermore, two electrode groups are provided on the housing 1 , one electrode group is electrically connected to the atomizing sheet 4 , and the other electrode group is electrically connected to the heating element 8 .
