Insert the heat-not-burn cigarette into the heating cylinder 22, and then press the control switch 9 to start smoking.

[0026] The working principle of the present invention will be specifically described in combination with the above embodiments. When the purchased heat-not-burn cigarette is suitable for being smoked using the central heating component 5, simply align the tail end of the cigarette with the dust-proof cover 12 and then press it downwards. When the cigarette can no longer descend, the two limit hooks 15 on the dust-proof cover 12 have been engaged with the two hooks 17. At this time, the heating needle 11 has penetrated into the cigarette. Then, a start signal is sent through the control switch 9, and the control module 7 controls the heating needle 11 to work. At this time, the user can smoke. After smoking is completed, the heating needle 11 is controlled to stop working. Then, press the pressing covers 20 on both sides. The push rod 21 pushes the lower end of the hook 17, and the hook 17 releases the limit hook 15. Under the action of the dust-proof cover return spring, the dust-proof cover 12 moves upwards and ejects the cigarette. When the purchased heat-not-burn cigarette is suitable for being smoked using the peripheral heating component 4, it is necessary to select a suitable peripheral heating component 4 according to the specifications of the cigarette. Then, slide the dust-proof cover 23 of the heating cylinder to expose the heating cylinder 22. Insert the cigarette into the heating cylinder 22. Then, a start signal is sent through the control switch 9, and the control module 7 controls the heating cylinder 22 to work. At this time, the user can smoke the cigarette. After smoking is completed, control the heating cylinder 22 to stop working. Then, pull out the cigarette and close the dust-proof cover 23 of the heating cylinder.
