[0065] It can be understood that the central heating element 9 is powered by the power supply 7 so that the central heating element 9 generates heat, thereby heating the cigarette.

[0066] Referring to FIG11 , a method for extracting smoke from a heating device includes the above-mentioned heating device. The method includes:

[0067] Step S1: Insert the cigarette from top to bottom onto the top plate 11 inside the heating chamber 1 and press downward, driving the heating chamber 1 downward so that the rotating wheel 3 moves downward and simultaneously stretches the spring. After reaching the limit position, the cigarette is released and fixed by the inclined slide 31 and the engaging groove 22.

[0068] Step S2: Control the power supply 7 to supply power to the central heating element 9 to heat the cigarette;

[0069] Step S3: After the cigarette is heated and smoked, press the cigarette downward again to drive the heating chamber 1 to continue to move downward, so that the wheel 3 rotates, the spring rebounds, and drives the wheel 3 and the heating chamber 1 to move upward, driving the cigarette upward. When the boss 12 reaches the highest point of the slide groove 21, the cigarette is separated from the central heating element 9, and the user can now take out the cigarette directly.

[0070] It should be noted that the cigarette is inserted from top to bottom into the top plate 11 inside the heating chamber 1 and pressed downward so that the central heating element 9 is inserted into the cigarette. The position of the cigarette can be fixed by the heating chamber 1 and the central heating element 9. By pressing the cigarette downward, the heating chamber 1 is driven to move downward, so that the wheel 3 moves downward while stretching the spring. After reaching the limit position, the cigarette is released and the cigarette is fixed by the inclined slide 31 and the clamping groove 22. The central heating element 9 is powered by the control power supply 7 to achieve heating of the cigarette. When the heating and smoking of the cigarette is finished, the cigarette is pressed downward again to drive the heating chamber 1 to continue to move downward, so that the wheel 3 rotates, the spring rebounds, and drives the wheel 3 and the heating chamber 1 to move upward, driving the cigarette upward. When the boss 12 reaches the highest point of the slide 21, the cigarette is separated from the central heating element 9, and the user can directly take out the cigarette.

[0071] In summary, the cigarette-taking device for a heating appliance provided by the present invention, when in use, inserts a cigarette into the heating chamber 1, and the heating chamber 1 moves downward, and the rotating wheel 3 is driven to move downward by cooperating with the slot 13 with a serrated structure at the bottom and the inclined slide 31 of the rotating wheel 3. During the downward movement of the rotating wheel 3, the spring is stretched, and when it reaches the limit position, the cigarette is released, and the inclined slide 31 disengages from the slide groove 21. Since the rotating wheel 3 is supported by the heating chamber 1 in the axial direction and cannot continue to move axially, under the action of pressure, the rotating wheel 3 rotates circumferentially, and then the spring partially rebounds, causing the inclined slide 31 of the rotating wheel 3 to fall off from the slot 13 at the bottom of the heating chamber 1, thereby engaging with the engaging groove at the bottom of the slide cylinder 2. 22 abuts and remains fixed, at this time the power supply 7 can be started normally to pass electric energy to the central heating element 9 to heat the cigarette; when the heating and smoking of the cigarette is finished, press the cigarette downward, the cigarette drives the heating chamber 1 to continue to move downward, so that the wheel 3 continues to rotate, and the inclined slide 31 slides through the clamping groove 22 and enters the slide groove 21. At this time, the wheel 3 moves upward under the elastic force of the spring, and the wheel 3 drives the heating chamber 1 to move upward. The circumferential boss 12 of the heating chamber 1 moves upward in the slide groove 21 of the slide cylinder 2. At this time, the heating chamber 1 drives the cigarette to move upward. When the boss 12 slides to the highest point of the slide groove 21, the cigarette is separated from the central heating element 9, and the user can directly take out the cigarette.

[0072] In addition to the smoke extraction device for heating appliances disclosed in the above embodiments, the present invention also provides a heating appliance including the above smoke extraction device for heating appliances.
