As shown in fig. 2 and 3, the first through hole 31, the first vent post 211, the second vent post 212, and the second through hole 41 are sequentially communicated with each other, and an air passage penetrating the power supply device is formed. Therefore, when the first atomizer is mounted in the first mounting portion 3, the second through hole 41 serves as an air inlet of the first atomizer. As shown in fig. 7, when the user sucks the first atomizer, the external air enters the first atomizer through the second through hole 41, the second vent pillar 212, and the first through hole 31 in this order. Meanwhile, air at the sensing end 221 of the pneumatic switch 22 enters the first atomization device 200 from the third vent column 213 through the first vent column 211 and the first through hole 31 in sequence, so that a negative pressure is formed at the sensing end 221 of the pneumatic switch 22, the pneumatic switch 22 is triggered, and finally the 100 power supply device supplies power to the first atomization device 200. Similarly, when the second atomizing device 300 is mounted in the second mounting portion 4, the first through hole 31 serves as an air inlet of the second atomizing device. As shown in fig. 8, when the user sucks the second atomizer 300, the external air enters the second atomizer through the first through hole 31, the first vent pillar 211, and the second through hole 41 in sequence. Meanwhile, air at the sensing end 221 of the pneumatic switch 22 enters the second atomization device 300 from the third vent column 213 through the second vent column 212 and the second through hole 41 in sequence, so that a negative pressure is formed at the sensing end 221 of the pneumatic switch 22, the pneumatic switch 22 is triggered, and finally the power supply device 100 supplies power to the second atomization device 300.

Preferably, the first vent column 211 and the second vent column 212 are coaxially arranged, so that the air circulation rate between the first vent column 211 and the second vent column 212 can be increased, which is beneficial to improving the atomization efficiency and increasing the concentration of aerosol. Further, the axial direction of the third vent column 213 forms an included angle with the axial directions of the first vent column 211 and the second vent column 212, and the included angle may be an acute angle, an obtuse angle or a right angle. Thus, the oil or the condensate flowing from the atomization passage into the first through hole 31 or the second through hole 41 is difficult to enter the third vent column 213, thereby functioning to protect the pneumatic switch 22.

Preferably, as shown in fig. 5 and 6, the third vent column 213 includes a small diameter section 2131 and a large diameter section 2132. One end of the small diameter section 2131 is connected to the first vent column 211 and the second vent column 212, and the other end is connected to the large diameter section 2132.

The second atomization device 300 is matched with the second installation part 4 and can be detachably connected with the second installation part 4. When the first atomization device 200 is installed in the first installation part 3, the first atomization passage 201 of the first atomization device 200 is communicated with the first through hole 31. When the second atomization device 300 is installed in the second installation part 4, the second atomization passage 301 of the second atomization device 300 is communicated with the second through hole 41. The aerosol generator of the embodiment can be configured with two atomization devices of different types, and share one trigger air passage and one pneumatic switch 22, so that the structure of the device is simplified, the cost is saved, and the individual requirements of users can be met. The specific structure of the power supply device of the aerosol generator refers to the above embodiments, and since the aerosol generator adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.
