step A, placing a tobacco 15 part 1501 of a cigarette into a cigarette cavity 101, and inserting a heating element 2 into the tobacco part 1501;
Step B, the first switch 3 is turned on, the power supply 4 supplies power to the heating body 2, the heating body 2 works and heats the tobacco part 1501, and the tobacco part 1501 generates smoke; during the operation of the heating element 2, the controller 5 is used for locking the second switch 6 to be in an off state, so that the electromagnet 8 is prevented from being electrified to push out the cigarettes 15 due to the fact that the second switch 6 is touched by mistake during the operation of the heating element 2.
Step C, when the heating time of the heating body 2 reaches the set time or the smoking state of a user is finished, the second switch 6 is controlled to be turned on, the electromagnet 8 generates a pushing force which is repulsive to the first magnetic piece 7 after being electrified, and the pushing force pushes the movable frame 1 to move in a direction away from the heating body 2 until all or part of the upper section of the heating body 2 is separated from the tobacco portion 1501;
Step d. The tobacco 15 portion 1501 of the cigarette is removed from the cigarette cavity 101.
As shown in fig. 12, in one embodiment, when the heating time of the heating element 2 reaches the set time, the first switch 3 is controlled to be turned off, specifically, in the step B, the detecting unit is further used to detect the operation state of the heating element 2, and the controller 5 determines whether the second switch 6 needs to be controlled to be turned on according to the operation state of the heating element 2 detected by the detecting unit, and if so, the step C is skipped.
In the step B of the process described above,
The method for detecting the working state of the heating element 2 by using the detection unit comprises the following steps: the duration t of the first switch 3, i.e. the duration of the heating element 2, is recorded by means of a timer 9.
The method for judging whether the second switch 6 needs to be controlled to be turned on by the controller 5 is as follows:
Comparing t with preset time t0, if t0 is larger than t, indicating that the working time of the heating element 2 is smaller than the preset time, and the heating element 2 needs to work continuously to generate heat, wherein at the moment, the electromagnet 8 is not required to generate magnetic force for pushing the movable frame 1, namely the electromagnet 8 is not required to be electrified, and the second switch 6 is not required to be controlled to be turned on; if t0 is less than or equal to t, the working time of the heating element 2 reaches the preset time, the heating element 2 stops working, the tobacco portion 1501 does not generate smoke for the user to inhale, at this time, the electromagnet 8 is required to generate magnetic force for pushing the movable frame 1 to push the tobacco portion 1501 out towards the smoking opening, that is, the electromagnet 8 needs to be electrified, and the second switch 6 needs to be controlled to be turned on. As shown in fig. 4, the moving frame 1 moves upward by the repulsive force of the electromagnet 8 to the first magnetic member 7, so that a part of the upper section of the heating element 2 is separated from the tobacco portion 1501, and oxide or residue fragments of the tobacco portion 1501 are prevented from being pulled out and remaining when the heating element 2 is cooled after being in thermal contact with the tobacco portion 1501, resulting in difficulty in cleaning the tobacco rod chamber 101 storing the tobacco portion 1501 and the heating element 2.
As shown in fig. 13, in one embodiment, after the user smokes, the first switch 3 is controlled to be turned off, specifically, in the step B, the detecting unit is further used to detect the working state of the heating element 2, and the controller 5 determines whether the second switch 6 needs to be controlled to be turned on according to the working state of the heating element 2 detected by the detecting unit, if so, the step C is skipped.
In the step B of the process described above,
The method for detecting the working state of the heating element 2 by using the detection unit comprises the following steps: collecting real-time temperature of the heating body 2 by using a temperature detector 10;
The method for judging whether the second switch 6 needs to be controlled to be turned on by the controller 5 is as follows:
The controller 5 is internally provided with the comparator 11, the real-time temperature of the heating body 2 detected by the temperature detector 10 is compared by the comparator 11, namely, two adjacent temperatures of the heating body 2 acquired by the temperature detector 10 are compared by the comparator 11, if the previous sampling temperature T n is less than or equal to the later sampling temperature T n+1, the heating body 2 is in a working state, heat is produced, a user normally smokes, at the moment, the electromagnet 8 is not required to generate magnetic force for pushing the movable frame 1, namely, the electromagnet 8 is not required to be electrified, and the second switch 6 is not required to be controlled to be turned on; if the previous sampling temperature T n > the next sampling temperature T n+1, the temperature of the heating element 2 is reduced or is falling, so it can be determined that the heating element 2 is stopped, that is, the tobacco portion 1501 does not generate smoke for the user to inhale, and at this time, the electromagnet 8 needs to generate a magnetic force for pushing the moving frame 1 to push the tobacco portion 1501 out towards the smoking opening, that is, the electromagnet 8 needs to be energized, and the second switch 6 needs to be controlled to be turned on. As shown in fig. 4, the moving frame 1 moves upward by the repulsive force of the electromagnet 8 to the first magnetic member 7, so that a part of the upper section of the heating element 2 is separated from the tobacco portion 1501, and oxide or residue fragments of the tobacco portion 1501 are prevented from being pulled out and remaining when the heating element 2 is cooled after being in thermal contact with the tobacco portion 1501, resulting in difficulty in cleaning the tobacco rod chamber 101 storing the tobacco portion 1501 and the heating element 2.
