Device capable of automatically igniting or heating a cigarette

1. A device for automatically igniting or heating a cigarette, comprising:

a heat source system,

a control system, and

an openable and closeable top cover;

wherein:

the heat source system comprises an electric heating chamber and an igniter, wherein the igniter is located at a bottom of the electric heating chamber;

the igniter comprises an electric heating element;

the electric heating chamber comprises at least one pair of first light passing holes, wherein the at least one pair of first light passing holes penetrate a wall of the electric heating chamber; and

the control system comprises a control circuit board, a mechanical switch, a mode switching switch, an infrared light source, a light sensing switch, and a device main circuit switch; wherein the mechanical switch controls the openable and closeable top cover to be opened or closed and controls the device main circuit switch to be turned on or off; the mode switching switch is configured to switch between an operation of the igniter and an operation of the electric heating chamber; the infrared light source, the light sensing switch, and the at least one pair of first light passing holes are aligned with one another; the light sensing switch controls the igniter or the electric heating chamber to be powered on or off.

2. The device according to claim 1 , wherein: a thermal insulation layer is arranged outside the electric heating chamber, and an air chamber is arranged between the electric heating chamber and the thermal insulation layer.

3. The device according to claim 1 , wherein: the device further comprises an auxiliary cigarette accommodation case.

4. The device according to claim 2 , wherein: at least one pair of second light passing holes are arranged on the thermal insulation layer, and the at least one pair of second light passing holes are aligned with the at least one pair of first light passing holes.

5. The device according to claim 1 , wherein: the device further comprises a battery and/or a charging interface.

6. The device according to claim 1 , wherein: the electric heating chamber is arranged in a manner allowing the electric heating chamber to slidably extend or retract relative to the device.

7. The device according to claim 6 , wherein: the device further comprises an electric heating chamber sliding button, and the electric heating chamber sliding button is fixed on an outer wall of the electric heating chamber and extends outside the device.

8. A method of automatically igniting or heating the cigarette by using the device according to claim 1 , comprising the following steps:

step (1): pressing the mechanical switch, unlocking a snap buckle of the openable and closeable top cover to open the openable and closeable top cover, triggering the device main circuit switch, wherein a main circuit of the device is connected, the infrared light source works to emit an infrared light, and the infrared light reaches the light sensing switch via the at least one pair of first light passing holes; setting the mode switching switch according to a type of a cigarette to be smoked; if the cigarette to be smoked is a carbon-heated cigarette or an end-ignition type cigarette, setting an ignition mode, wherein only the igniter is powered on to operate in the ignition mode, and the electric heating chamber is not powered on to operate in the ignition mode; if the cigarette to be smoked is an electric heating cigarette, setting a heating mode, wherein only the electric heating chamber is powered on to operate in the heating mode, and the igniter is not powered on to operate in the heating mode; entering a standby state of the device; and

step (2): inserting the cigarette to be smoked into the electric heating chamber, when the cigarette to be smoked blocks the infrared light, according to a mode setting of the mode switching switch, activating the igniter to be powered on to operate to ignite an insertion end of the cigarette to be smoked by the light sensing switch, or activating the electric heating chamber to be powered on to operate to circumferentially heat the cigarette to be smoked by the light sensing switch; and entering a working state of the device.

9. The method according to claim 8 , wherein, the method further comprises the following step:

step (3): sensing the infrared light and restoring the device to the standby state by the light sensing switch after the cigarette to be smoked is removed from the electric heating chamber.

10. The method according to claim 8 , wherein, the method further comprises the following step:

step (4) cutting off the main circuit of the device by the device main circuit switch after the openable and closeable top cover is closed, and entering an off state of the device.

11. The method according to claim 8 , wherein: a thermal insulation layer is arranged outside the electric heating chamber, and an air chamber is arranged between the electric heating chamber and the thermal insulation layer.

12. The method according to claim 8 , wherein: the device further comprises an auxiliary cigarette accommodation case.

13. The method according to claim 8 , wherein: at least one pair of second light passing holes are arranged on the thermal insulation layer, and the at least one pair of second light passing holes are aligned with the at least one pair of first light passing holes.

14. The method according to claim 8 , wherein: the device further comprises a battery and/or a charging interface.

15. The method according to claim 8 , wherein: the electric heating chamber is arranged in a manner allowing the electric heating chamber to slidably extend or retract relative to the device.
