The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of the present invention provides an aerosol generating device, which includes an atomizer 100 and a power supply device (not shown) electrically connected to the atomizer 100, wherein, in use, the power supply device is used to provide electric energy to the atomizer 100, so as to heat an aerosol-forming substrate stored in the atomizer 100, and the aerosol-forming substrate is atomized under the heating action to form smoke for a user to inhale.

The atomizer 100 includes a reservoir 10, a bottom cap assembly 30, a vent assembly 50, an atomizing assembly 70, and a mouthpiece assembly 90.

Referring also to figure 2, a reservoir 10 is provided with a reservoir chamber 11 for storing an aerosol-forming substrate, and a bottom cap component 30 and a mouthpiece component 90 are mounted to the bottom and top of the reservoir 10 respectively. The ventilation assembly 50 has one end slidably coupled to the bottom cap assembly 30 and the other end extending into the reservoir 11 and fixedly connected to the mouthpiece assembly 90. Meanwhile, an atomizing cavity 530 having a liquid inlet 5301 is disposed in the ventilation assembly 50, and an atomizing assembly 70 is disposed in the atomizing cavity 530, and is capable of heating the aerosol-forming substrate adsorbed on the atomizer 100 through the liquid inlet 5301 when the power supply device supplies power to the atomizer, so as to atomize the aerosol-forming substrate into smoke, and the smoke is inhaled by the user through the ventilation assembly 50 and the mouthpiece assembly 90 under the smoking action of the user.

Referring to fig. 2 and 4, the mouthpiece component 90 is slidable relative to the liquid reservoir 10 under an external force between an activation position (shown in fig. 2) and a use position (shown in fig. 4). When the mouthpiece component 90 is in the position to be activated (i.e. when the nebulizer 100 is in transport or not in use), the bottom cap component 30 closes the liquid inlet 5301, so that the nebulizer 100 is completely isolated from the aerosol-forming substrate within the liquid reservoir 10, avoiding long-term immersion of the nebulizer 100 in the aerosol-forming substrate, which could lead to deterioration of the aerosol-forming substrate and affect the taste of subsequent smoking; when the cigarette holder assembly 100 is located at the use position, the liquid inlet 5301 is communicated with the liquid storage cavity 11 and the atomization cavity 530, so that aerosol-forming substrates in the liquid storage cavity 11 can be adsorbed by the atomization assembly 70 located in the atomization cavity 530 through the liquid inlet 5301, and are heated under the action of electric energy provided by the power supply device to form smoke.
