The working method of the low-temperature smoke of the present invention includes:

Step A. Put the tobacco part 1501 of the cigarette 15 into the cigarette cavity 101, while the heating element 2 is inserted 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, heats the tobacco part 1501, and the tobacco part 1501 generates smoke; during the working process of the heating body 2, the controller 5 is used to lock the second switch 6 is in an off state to prevent the electromagnet 8 from being energized to work and pushing out the cigarette 15 due to mistakenly touching the second switch 6 during the working process of the heating element 2 .

Step C. When the heating time of the heating body 2 reaches the set time or the user's smoking state is completed, the second switch 6 is controlled to be turned on, and the electromagnet 8 is energized to generate a thrust repulsive with the first magnetic member 7, and the thrust pushes The moving frame 1 moves away from the heating body 2 until all or a part of the upper section of the heating body 2 is separated from the tobacco part 1501;

Step D. Take out the tobacco portion 1501 of the cigarette 15 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 method further includes detecting the heating element with a detection unit. 2, the controller 5 determines whether it is necessary to control the second switch 6 to be turned on according to the working state of the heating element 2 detected by the detection unit, and if so, jumps to step C.

In the step B,

The method of using the detection unit to detect the working state of the heating element 2 is as follows: using the timer 9 to record the continuous conduction time t of the first switch 3 , that is, the continuous working time of the heating element 2 .

The method for the controller 5 to judge whether it is necessary to control the conduction of the second switch 6 is as follows:

Compare t with the preset time t0. If t0>t, it means that the working time of the heating element 2 is less than the preset time, and the heating element 2 needs to continue to work to generate heat. At this time, the electromagnet 8 is not required to generate the magnetic force to push the moving frame 1. , that is, the electromagnet 8 does not need to be energized, and it is not necessary to control the second switch 6 to be turned on; if t0≤t, it means that the working time of the heating element 2 reaches the preset time, the heating element 2 stops working, and the tobacco part 1501 does not generate smoke for supply. When the user smokes, the electromagnet 8 needs to generate a magnetic force to push the moving frame 1 to push the tobacco part 1501 toward the smoking port, that is, the electromagnet 8 needs to be powered on, and the second switch 6 needs to be turned on. As shown in FIG. 4 , under the action of the repulsive force of the electromagnet 8 to the first magnetic member 7 , the moving frame 1 moves upward, so that a part of the upper section of the heating body 2 is separated from the tobacco part 1501 to prevent the heating body 2 from thermally contacting the tobacco part 1501 When it is re-cooled, it is pulled out and the oxides or residual slag fragments of the tobacco part 1501 remain, which makes it difficult to clean the cigarette chamber 101 and the heating element 2 in which the tobacco part 1501 is stored.

As shown in FIG. 13 , in one embodiment, after the user completes the smoking state, the first switch 3 is controlled to be turned off. Specifically, the step B further includes using a detection unit to detect the working state of the heating element 2 , the controller 5 determines whether it is necessary to control the second switch 6 to be turned on according to the working state of the heating element 2 detected by the detection unit, and if so, jumps to step C.

In the step B,

The method of using the detection unit to detect the working state of the heating body 2 is: using the temperature detector 10 to collect the real-time temperature of the heating body 2;

The method for the controller 5 to judge whether it is necessary to control the conduction of the second switch 6 is as follows:

A comparator 11 is provided inside the controller 5, and the real-time temperature of the heating element 2 detected by the temperature detector 10 is compared by the comparator 11, that is, the heating element 2 collected by the temperature detector 10 is compared by the comparator 11. Two adjacent temperatures are compared. If the previous sampling temperature T _n ≤ the next sampling temperature T _n+1 , it means that the heating element 2 is working, producing heat, and the user is smoking normally. At this time, no electromagnetic field is required. The iron 8 generates a magnetic force that pushes the moving frame 1, that is, the electromagnet 8 does not need to be energized, and does not need to control the second switch 6 to be turned on; if the previous sampling temperature T _n > the next sampling temperature T _n+1 , it means heat generation The temperature of the body 2 has a downward trend or is decreasing, so it can be judged that the heating body 2 has stopped working, that is to say, the tobacco part 1501 does not generate smoke for the user to smoke. Pushing the tobacco part 1501 toward the smoking port means that the electromagnet 8 needs to be energized, and the second switch 6 needs to be turned on. As shown in FIG. 4 , under the action of the repulsive force of the electromagnet 8 to the first magnetic member 7 , the moving frame 1 moves upward, so that a part of the upper section of the heating body 2 is separated from the tobacco part 1501 to prevent the heating body 2 from thermally contacting the tobacco part 1501 When it is re-cooled, it is pulled out and the oxides or residual slag fragments of the tobacco part 1501 remain, which makes it difficult to clean the cigarette chamber 101 and the heating element 2 in which the tobacco part 1501 is stored.
