In addition, in the first connection position A and the second connection position B, the power supply device 10 and the aerosol generating device 20 are both kept in a connected state instead of being disconnected from each other.

In order to facilitate that the power supply device 10 and the aerosol generating device 20 of the embodiment can be switched in two connection states, the power supply device 10 and the aerosol generating device 20 are designed to be flexibly connected; specifically, as shown in FIG. 4 and FIG. 5 In the preferred embodiment, the sliding connection is adopted, and the power supply device 10 is in the shape of an elongated shape, which has a proximal end 110 and a distal end 220 opposite along the length direction; A chute 13 is provided in the length direction, and a sliding button 23 adapted to the sliding groove 13 is provided on the aerosol generating device 20.

Of course, based on the same positioning function, the above positioning hole 12 and pogo pin 22 used in the embodiment can be replaced with positioning posts/slots, limiting structures, etc. that can guide the sliding position.

Based on the structure and function realization of these details, the detailed structure and assembly of the aerosol generating device 20 in this embodiment can be referred to as shown in the exploded schematic diagram of FIG. The middle cover 230 for assisting the assembly and fixing of the main substrate 220; wherein, the slider 23 is arranged on the outer casing 210, the conductors 21 and the pogo pins 22 are both arranged on the main substrate 220 and penetrate through the middle cover 230 and the outer casing 210 The corresponding mounting holes on the power supply device 10 can be connected to the conductive contacts 11 and the positioning holes 12 on the power supply device 10 until they are partially exposed outside the surface of the outer casing 210 . In addition, the main core functional component, the atomizer 24 , is also connected to the main substrate 220 , and is also connected to the conductor 21 to conduct electricity.

The end cover 2412 is also provided with an air inlet hole, which is arranged opposite to the axial through hole of the porous body 2414. When sucking the nozzle rod 242, a negative pressure is generated inside the outer casing 2410, and the outside air enters through the air inlet hole. To the outer casing 2410, follow the direction of arrow R2 and carry the smoke aerosol generated in the porous body 2414 into the smoke channel 2421 of the nozzle rod 242 until it is transferred to the upper end of the nozzle rod 242 to be sucked; a complete smoke is formed.

When the airflow sensor 27 detects that the user sucks the nozzle rod 242 of the atomizer 24 to generate air circulation, the control switch circuit is turned on to supply power to the atomizer 24; and when the airflow sensor 27 does not detect airflow, the switch circuit is in Disconnect to prevent the atomizer 24 from being triggered by mistake. Meanwhile, it can be seen from the above that only when the airflow sensor 27 is in the second connection position B, it is connected to the power supply device through the conductor 21 and is in a conductive state. Compared with the normally open method in which the sensor is arranged on the circuit board of the power supply part to conduct stable conduction in the existing classic flat cigarette, it can better prevent false triggering and improve the service life of the sensor.

The above sliding connection and positioning methods are based on the preferred design of the shape of the vertically long power supply device 10 and the aerosol generating device 20 used in the embodiment; for other types of shapes or products, the active connection method can be based on the shape of the product.

Pass to power the atomizer to prevent false triggering.

Further in this embodiment, since the first airflow sensor 271b and the second airflow sensor 272b are located on a straight line in the longitudinal direction in the illustrated assembly, when the distance between the two is not far enough, it is possible that the first airflow sensor 271b The air flow in the smoke circulation path when the second atomizer 40 is puffing may be sensed, or conversely, the second air flow sensor 272b may sense the air flow in the smoke circulation path when the first atomizer 24b is puffing.

Based on the design idea, the airflow isolation plate 61 is simultaneously integrated with the functions of the first airflow isolation portion 511 and the second airflow isolation portion 512 in the previous embodiment.

Further in this embodiment, the first airflow guide body 621 and the second airflow guide body 622 are provided separately from the airflow separation plate 61 . Its structure is the same as the design in FIG. 14 and FIG. 15 , and will not be repeated here.
