Referring to fig. 1, an implementation environment of a method for controlling heating of an incombustible electronic smoking article according to a first embodiment of the present application includes heating the incombustible electronic smoking article 100 and a cigarette 200. The heating non-combustion electronic smoking set 100 comprises a plurality of heating devices 101 arranged at intervals, and the plurality of heating devices 101 can be controlled independently by the control module 102, so that the cigarette 200 can be heated in a segmented mode, the heating efficiency is more reasonable compared with the whole cigarette, the smoke quantity can be suitable, and the service time of the cigarette can be prolonged.
When a user draws a holder of the cigarette 200, air enters the smoking set 100, passes through the cigarette 200, and conveys the aerosol emitted after being baked in the cigarette 200 to a user's mouth for the user to inhale.
A second embodiment of the present application provides a heating non-combustible electronic smoking article 100, referring to fig. 2, the heating non-combustible electronic smoking article 100 includes an infrared ceramic heating tube 10 and a controller 30. Wherein the infrared ceramic heating tube 10 comprises a ceramic tube 11 and at least two heating elements 12.
Wherein the ceramic tube 11 is used for accommodating the cigarettes 200. When the ceramic tube 11 is heated, a large amount of infrared rays are excited, and the infrared rays generated by the excitation heat the cigarettes 200 accommodated in the ceramic tube 11. In the embodiment, the infrared rays are not blocked by other mediums, and the utilization rate is high, so that the heating efficiency is high.
It is understood that the material of the ceramic tube 11 may be a magnesia-ferrichrome spinel-cordierite composite ceramic. The composite Mg-Fe-Cr spinel-cordierite ceramic is prepared by adding Mg-Fe-Cr spinel into low-expansion base material cordierite in the form of additive, and has infrared radiation efficiency up to 90% and stable structure. Thus, the ceramic tube 11 is made to have a high infrared radiation efficiency. It will be appreciated that the wavelength of the infrared light generated by the ceramic tube 11 matches the frequency of the infrared light of the cigarette 200, i.e. the frequency of the infrared light matches the molecular vibration frequency of the tobacco in the cigarette 200, the molecular movement of the tobacco in the cigarette 200 is more intense, and thus the optimal heating effect can be obtained.
At least two heating components 12 are disposed on the ceramic tube 11 for heating the ceramic tube 11 to excite the ceramic tube 11 to generate infrared rays. It will be appreciated that in some embodiments, the heating assembly 10 may be in the form of a conductive paste coating or a heating filament. In some embodiments, the conductive paste coating as the heating component can be tungsten-manganese paste or the like, and is coated on the outer wall or the middle layer of the ceramic tube, so that the ceramic tube can be heated when the conductive paste coating is electrified. It will be appreciated that for multiple heating elements, it is necessary to apply each of the conductive paste coatings in sections. In some embodiments, the heating wire serving as the heating component can be wound on the outer wall of the infrared ceramic component, and when the heating wire is electrified, the ceramic tube can be heated.
Each heating element 12 is sequentially arranged along the axial direction of the ceramic tube 11, and one heating element 12 corresponds to a section of the ceramic tube 11, for example, heating element 1# corresponds to a section a of the ceramic tube, heating element 2# corresponds to a section B of the ceramic tube, and heating element 3# corresponds to a section C of the ceramic tube. When a heating component 1# heats, the section A of the corresponding section of the ceramic tube is heated to generate infrared rays so as to heat the corresponding section of the cigarette in a sectional manner.
It will be appreciated that each heating element 12 is made of a thermally sensitive material, i.e. the electrical resistance varies with temperature. For example, when the thermosensitive material is a positive temperature coefficient thermosensitive material, the temperature of the heating member increases, and the resistance value thereof also increases, but when the thermosensitive material is a negative temperature coefficient thermosensitive material, the temperature of the heating member increases, and the resistance value thereof decreases. Thus, the resistance change of the heating element 12, and thus the temperature change, and thus the pumping action, can be detected by the corresponding detection circuit.
The controller is connected with each heating component respectively, so that the voltage of each heating component can be acquired, and the heating power of each heating component is controlled. Specifically, the controller may be connected to each heating element 12 via a detection circuit. The detection circuit is used for collecting the voltages and the currents at the two ends of each heating component in real time and sending the voltages and the currents at the two ends to the controller, so that the controller can obtain the resistor according to the voltages and the currents at the two ends. It will be appreciated that the controller may also control the heating power of each heating assembly by controlling the corresponding power supply unit 40.
During the preheating stage, the controller 30 controls the heating elements 12 to heat, so that the ceramic tube 11 is heated as a whole to generate infrared rays, and the infrared rays radiate the whole cigarette 200 to rise to a smoking temperature, and it is understood that the smoking temperature is higher than the temperature for smoking tobacco in the cigarette to emit aerosol, so that the temperature of the cigarette cannot reach the temperature for smoking tobacco in the cigarette to emit aerosol after air enters. It will be appreciated that each heating element 12 is connected to a power supply unit 40, the power supply unit 40 supplies power to each heating element 12, and the power supply unit 40 generally includes various power supply circuits and control circuits, so that the power supply unit 40 may intermittently supply power to each heating element 12 under the control of the controller 30, so as to maintain the temperature of each heating element 12 at a predetermined temperature, for example, by adjusting the duty ratio of the current or voltage output from the power supply unit to each heating element 12 to maintain each heating element 12 at a predetermined temperature, so as to heat the ceramic tube 11. Thus, the ceramic tube 11 can radiate infrared rays of a certain energy to heat the cigarette 200, and the temperature of the cigarette 200 is kept rising to the smoking temperature. It will be appreciated that controlling the temperature of the heating assembly 12 is equivalent to controlling the baking temperature of the ceramic tube 11 on the cigarette 200.
When the temperature of the cigarette reaches the smoking temperature, the smoking stage is entered, and at this stage, the user needs to smoke the baked aerosol at a section of the cigarette, at this time, the controller 30 selects any one of the heating elements 12 as a target heating element, controls the target heating element to continue heating, so that a section of the cigarette 200 corresponding to the target heating element is controlled to the smoking temperature, and controls the remaining heating elements except the target heating element to stop heating. It will be appreciated that the pumping temperature is a temperature at which the cigarette is baked into the aerosol, and is slightly below the smoking temperature described above. In this embodiment, only one area of the cigarette 200 corresponding to the target heating element is baked to give aerosol, and the other area is not baked to give aerosol, so that the heating efficiency is prevented from being too high due to the overall baking of the cigarette.
In order to allow continuous baking of the segments of the cigarette, the smoking article 100 should also have the ability to detect whether the tobacco is consumed in the segment of the cigarette being baked, and when consumed, begin the baking of the next segment of the cigarette 200. In conventional arrangements, the suction is typically detected by providing an additional sensor, such as an additional airflow sensor or the like, to detect the number of suction openings, which is compared to the nominal number of suction openings that the section of tobacco can supply to determine if the tobacco is depleted in the section of the cigarette being roasted.
In this embodiment, the controller 30 determines the pumping parameters based on the resistance change of the remaining heating element 12, and thus determines whether the tobacco in a section of the cigarette 200 corresponding to the target heating element is consumed or not based on the pumping parameters, without requiring an additional sensor. Specifically, as shown in fig. 3, when a user sucks, the temperature of air is lower due to the air flow entering, the temperature of the ceramic tube 11 is reduced, the temperature of the residual heating components made of the thermistor material is reduced, the resistance of the residual heating components is changed first, the controller is connected with each heating component, the controller can acquire the first change of the resistance of the residual heating components, the controller can increase the heating power of the target heating components, the temperature of the ceramic tube is quickly raised to the smoking temperature, when the suction is stopped, the temperature of the ceramic tube is instantaneously raised to the smoking temperature due to the fact that the air stops flowing, the temperature of the residual heating components is raised, the resistance of the residual heating components is changed second, the controller reduces the heating power of the target heating components after the controller acquires the second change of the resistance of the residual heating components, the temperature of the ceramic tube is pulled back to the suction temperature, the temperature of the residual heating components is lowered to the suction temperature, and the resistance of the residual heating components is changed third. Thus, each time a cigarette is smoked, the resistance of the remaining heating element will change first, second and third, and the smoking action can be determined from the change in resistance of the remaining heating element. I.e. when the resistance periodically undergoes a first, second and third change, a pumping action is determined. The number of puffs and the single duration may reflect a puff parameter for evaluating the puff of the segment of the cigarette. Thus, the suction parameter is determined according to the suction action, and further, whether the tobacco in a section of the cigarette corresponding to the target heating assembly is consumed or not can be determined according to the suction parameter. It is determined whether the tobacco in a section of the cigarette corresponding to the target heating element is depleted. When depleted, the controller 30 selects a heating element from the remaining heating elements 12 as a new target heating element, and begins the heating use and monitoring of the next segment of the cigarette 200. Therefore, the sectional intelligent heating of the cigarettes can be realized, the smoking time of the cigarettes is prolonged, an additional sensor is not needed, and the structure is simple.
It is to be appreciated that the controller may be a general purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a single chip, ARM (Acorn RISC Machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof.
In some real-time examples, the pumping parameters include a pumping port count or a pumping duration, wherein the pumping port count is a number of cycles in which the first, second, and third changes occur in the resistance, and the pumping duration is a duration in which the first, second, and third changes are accumulated.
When the pumping parameter is the pumping port number, the number of changes of the resistance can be taken as the pumping port number by accumulating the number of changes. It is understood that the variation refers to a periodic variation from a first variation to a third variation.
When the pumping parameter is pumping duration, the varying duration can be used as the pumping duration by accumulating the varying duration of the resistance. It is understood that the duration of the change refers to the sum of the individual durations of the resistance between the first change to the second change and the third change.
In some embodiments, when the puff parameter is greater than or equal to a first preset threshold, it is determined that tobacco is depleted in a region of the cigarette corresponding to the target heating assembly. In this real-time example, the first preset threshold corresponds to a nominal suction parameter of the tobacco segment, for example, when the suction parameter is the suction port number, the first preset threshold is the nominal suction port number, and when the suction parameter is the suction duration, the first preset threshold is the nominal suction duration. Thus, the puff parameter can reflect the puff of the user, and then the puff parameter can be compared to a first preset threshold that can reflect the nominal puff of the segment of tobacco, and if the puff parameter is greater than or equal to the first preset threshold, the segment is depleted of tobacco.
In this embodiment, by setting each heating element 12 to be made of a thermistor material, and combining the feature of air intake in smoking, the smoking action can be detected through resistance change, and the smoking parameter is calculated, and then the smoking parameter is compared with the first preset threshold value, so that whether the tobacco in a section of the cigarette corresponding to the target heating element is consumed or not can be determined, and an additional sensor is not needed, so that the electronic smoking set has a simple structure.
Considering that some users draw cigarettes at intervals, for example, 2 minutes after drawing a mouth, during the interval period, the tobacco in the area corresponding to the target heating component is still baked and is consumed in small amounts, in this case, in order to make the result of the determination of whether to consume the tobacco in the area corresponding to the target heating component accurate, in some embodiments, the step of determining whether to consume the tobacco in the area corresponding to the target heating component further includes:
acquiring accumulated heating time of the target heating assembly;
and if the accumulated heating time is greater than or equal to a second preset threshold, determining that the tobacco consumption in a section of the cigarette corresponding to the target heating component is depleted.
Wherein the accumulated heating time refers to the total time for which tobacco in a section corresponding to the target heating component is accumulated to be baked. And taking the accumulated heating time as an evaluation standard, wherein the second preset threshold value is a time threshold value reflecting that the cigarette section can be baked, and if the accumulated heating time is greater than or equal to the second preset threshold value, determining that the tobacco consumption in a section of the cigarette corresponding to the target heating component is depleted.
In this real-time example, the accumulated heating time is used as an evaluation criterion, so that the tobacco in a section of area corresponding to the target heating component is still baked in an interval stage, and errors caused by small consumption of tobacco can be avoided, so that judgment is more accurate, and further, the heating of the section is more sensitive.
In some embodiments, the step of determining whether the tobacco in the region corresponding to the target heating element is depleted further comprises:
acquiring the accumulated heating time and the real-time heating power of the target heating component, and determining the accumulated heating energy according to the accumulated heating time and the real-time heating power of the target heating component;
and if the accumulated heating energy is greater than or equal to a third preset threshold, determining whether the tobacco in a section of the tobacco corresponding to the target heating component is consumed completely.
In this embodiment, the accumulated heating time and the real-time heating power are integrated to obtain the accumulated heating energy consumed for heating the cigarette segment. The third preset threshold is the energy required by the baking of the tobacco in a section of the tobacco corresponding to the target heating component. When the accumulated heating energy is greater than or equal to a third preset threshold, determining that the tobacco consumption in a section of the cigarette corresponding to the target heating component is depleted
In some embodiments, the heating assembly 12 includes at least two electrical conductors, for example, at least two electrical conductors are uniformly distributed along the circumference of the ceramic tube, and it is understood that any two electrical conductors of the at least two electrical conductors form a capacitor, when the cigarette is not inserted, the medium in the middle of the capacitor is ceramic and air, and when the cigarette is inserted into the ceramic tube, the medium in the middle of the capacitor includes ceramic and the cigarette, and the medium changes, so that the capacitance value of the capacitor also changes. Based on the above principle, the controller 30 may determine that the cigarette is inserted into or removed from the ceramic tube according to the change of the capacitance after acquiring the capacitance between any two conductors of the at least two conductors.
For the safety of the smoking set, when the insertion of the cigarettes into the ceramic tube is detected, the cigarettes are preheated, namely, the heating assemblies are controlled to heat, so that the cigarettes are heated to the smoking temperature by the infrared radiation generated by the ceramic tube. When the cigarettes are detected to move out of the ceramic tube, each heating component is controlled to stop heating. Thus, abnormal empty heating of the smoking set can be prevented.
In some embodiments, the infrared ceramic heating tube further comprises a heat insulation component (not shown), the heat insulation component is sleeved on the outer wall of the ceramic tube 11 and wraps each heating component 12 for heat preservation, so that heat dissipation is prevented, and in addition, scalding of a user is prevented. It will be appreciated that the insulation assembly may be made of an alumina composite based porous ceramic or like insulation material.
Note that the heating non-combustible electronic smoking set shown in fig. 2 shows only the constituent elements related to the present embodiment. Accordingly, it will be appreciated by those skilled in the art to which this embodiment relates that the heated non-combustible electronic smoking article may also include other conventional components in addition to those shown in FIG. 2.
In summary, the heating non-combustion electronic smoking set provided by the embodiment of the application includes an infrared ceramic heating tube and a controller, the infrared ceramic heating tube includes a ceramic tube and at least two heating components, and the controller is respectively connected with each heating component. The ceramic tube is used for accommodating cigarettes, at least two heating components are arranged on the ceramic tube and are sequentially arranged along the axial direction of the ceramic tube, one heating component corresponds to one section of the ceramic tube, firstly, the controller controls the at least two heating components to heat, so that the cigarettes are heated to the smoking temperature by infrared radiation generated by the ceramic tube, then, the target heating component is controlled to continue heating, so that one section of the cigarette corresponding to the target heating component is controlled to the smoking temperature, the rest heating components are controlled to stop heating, when a user sucks, the temperature of the rest heating components is instantaneously reduced due to air flow, the temperature of the rest heating components made of thermistor materials is also reduced, the resistance of the rest heating components is also reduced, the first change of the resistance of the rest heating components is obtained due to the fact that the controller is connected with each heating component, the controller can increase the heating power of the target heating components, so that the temperature of the ceramic tube is quickly risen to the smoking temperature, when the suction is stopped, the temperature of the ceramic tube is instantaneously risen to the smoking temperature, the rest heating components is also increased, the resistance of the rest heating components is also increased, the second change of the rest heating components is also controlled to obtain the second change of the resistance, the rest heating components is also reduced, and the second change of the rest heating components is obtained, and the rest heating components are heated, and the third change of the rest heating components is obtained. Thus, each time a cigarette is smoked, the resistance of the remaining heating element changes first, second and third, the smoking action and the smoking parameter can be determined according to the change of the resistance of the remaining heating element, and further, whether the tobacco in a section of the cigarette corresponding to the target heating element is consumed or not can be determined according to the smoking parameter; when the cigarette is consumed, a heating component is selected from the rest heating components to serve as a new target heating component, and heating use of the next section of the cigarette is started. Therefore, the sectional intelligent heating of the cigarettes can be realized, the smoking time of the cigarettes is prolonged, an additional sensor is not needed, and the structure is simple.
The third embodiment of the present application provides a method for controlling a heating non-combustion electronic smoking set, which may be applied to any suitable heating non-combustion electronic smoking set, where the heating non-combustion electronic smoking set includes a ceramic tube and at least two heating components, the ceramic tube is used to accommodate cigarettes, the at least two heating components are disposed on the ceramic tube, the at least two heating components are sequentially arranged along an axial direction of the ceramic tube, one heating component corresponds to a section of an area of the ceramic tube, and the at least two heating components are made of a thermistor material, that is, a resistance changes with a temperature change, for example, the higher the temperature of the heating component is, the greater the resistance value of the heating component is. Thus, the resistance value of the heating assembly can be detected by the corresponding detection circuit, and the temperature change can be detected.
When one heating component is electrified and heated, a section of the corresponding ceramic tube is heated to generate infrared rays so as to heat a section of the corresponding cigarette section in a sectional mode.
As shown in fig. 4, the method S20 includes:
s21: and controlling the at least two heating assemblies to heat so that the cigarettes are heated to the smoking temperature by the infrared radiation generated by the ceramic tube.
S22: and after the temperature of the cigarette reaches the smoking temperature, controlling a target heating assembly to continue heating so as to control a section of the cigarette corresponding to the target heating assembly to the sucking temperature, and controlling the heating assemblies remaining except the target heating assembly to stop heating, wherein the target heating assembly is any one of the at least two heating assemblies.
S23: and acquiring the resistance of at least one heating component in the rest heating components, and determining the pumping parameters according to the change of the resistance.

S25: when the tobacco consumption in the section of the cigarette corresponding to the target heating element is depleted, selecting a heating element from the rest heating elements as a new target heating element, and returning to the step S22.
In the preheating stage, the heating assemblies are controlled to heat, so that the ceramic tube is heated integrally to generate infrared rays, the infrared rays radiate the whole cigarette to heat up to the smoking temperature, and the smoking temperature is understood to be the temperature at which the tobacco in the cigarette can be baked to emit aerosol. It will be appreciated that each heating element is connected to a power supply unit, the power supply unit supplies power to each heating element, and the power supply unit generally includes various power supply circuits and control circuits, so that the power supply unit may intermittently supply power to each heating element, so as to maintain the temperature of each heating element at a preset temperature, for example, by adjusting the duty cycle of the current or voltage output to each heating element by the power supply unit, so as to maintain each heating element at the preset temperature, so as to heat the ceramic tube. Therefore, the ceramic tube can radiate infrared rays with certain energy to heat the cigarettes, and the temperature of the cigarettes is kept to be raised to the smoking temperature. It is understood that controlling the temperature of the heating assembly is equivalent to controlling the baking temperature of the ceramic tube to the cigarette.
When the temperature of the cigarette reaches the smoking temperature, the smoking stage is entered, and at the stage, a user needs to smoke the baked aerosol of one section of the cigarette, at the moment, any one heating component is selected from all the heating components to serve as a target heating component, the target heating component is controlled to continue heating, so that one section of the cigarette corresponding to the target heating component is controlled to the smoking temperature, and the heating components which are remained except the target heating component are controlled to stop heating. In this embodiment, only one area of the cigarette corresponding to the target heating component is baked to give aerosol, and other area sections are not baked to give aerosol, so that the too high heating efficiency caused by the whole baking of the cigarette can be avoided.
In order to allow continuous baking of the segments of the cigarette, the smoking device should also have the ability to detect whether the tobacco is consumed in the segment of the cigarette being baked, and when consumed, begin the baking of the next segment of the cigarette. In conventional arrangements, the suction is typically detected by providing an additional sensor, such as an additional airflow sensor or the like, to detect the number of suction openings, which is compared to the nominal number of suction openings that the section of tobacco can supply to determine if the tobacco is depleted in the section of the cigarette being roasted.
In this embodiment, the pumping parameter is determined according to the resistance change of the remaining heating element, and thus it can be determined whether the tobacco in a section of the cigarette corresponding to the target heating element is consumed or not according to the pumping parameter, without an additional sensor. Specifically, as shown in fig. 3, when a user sucks, due to the fact that air flow enters, the temperature of air is low, the temperature of the ceramic tube is reduced, the temperature of the residual heating component made of the thermistor material is reduced, the resistance of the residual heating component is reduced, accordingly, the resistance of the residual heating component is reduced to a first change, the heating power of the target heating component is increased, the temperature of the ceramic tube is quickly raised to the smoking temperature, when the user stops sucking, the temperature of the ceramic tube is instantaneously raised to the smoking temperature due to the fact that air stops flowing in, the temperature of the residual heating component is raised, the resistance of the residual heating component is reduced, the heating power of the target heating component is reduced after the resistance of the residual heating component is reduced, the temperature of the ceramic tube is pulled back to the sucking temperature, the temperature of the residual heating component is reduced to the smoking temperature, and the resistance of the residual heating component is changed to a third. Thus, each time a cigarette is smoked, the resistance of the remaining heating element will change first, second and third, and the smoking action can be determined from the change in resistance of the remaining heating element. I.e. when the resistance periodically undergoes a first, second and third change, a pumping action is determined. The number of puffs and the single duration may reflect a puff parameter for evaluating the puff of the segment of the cigarette. Thus, the suction parameter is determined according to the suction action, and further, whether the tobacco in a section of the cigarette corresponding to the target heating assembly is consumed or not can be determined according to the suction parameter. It is determined whether the tobacco in a section of the cigarette corresponding to the target heating element is depleted. When the consumption is over, a heating component is selected from the rest heating components to serve as a new target heating component, and heating use and monitoring of the next section of the cigarette are started. Therefore, the sectional intelligent heating of the cigarettes can be realized, the smoking time of the cigarettes is prolonged, an additional sensor is not needed, and the structure is simple.
When the consumption is over, a heating element is selected from the remaining heating elements as a new target heating element, heating and monitoring of the next section of the cigarette are started, namely, the step S22 is returned to, the corresponding section of the cigarette is heated through the new target heating element, meanwhile, whether the tobacco in the section is consumed or not is monitored, if the consumption is over, a heating element is selected from the remaining heating elements as the new target heating element, until all sections of the cigarette are consumed, and at the moment, the smoking set stops working.
Therefore, the sectional intelligent heating of the cigarettes can be realized, the smoking time of the cigarettes is prolonged, an additional sensor is not needed, and the structure is simple.
In some embodiments, the suction parameter includes a suction port number or a suction duration. The number of the suction ports is the number of periods of the first change, the second change and the third change of the resistance, and the suction duration is the duration of accumulating each of the first change, the second change and the third change.

When the pumping parameter is pumping duration, the varying duration can be used as the pumping duration by accumulating the varying duration of the resistance. It is understood that the duration of the change refers to the sum of the individual durations of the resistance between the first change to the second change and the third change.
In some embodiments, step S24 specifically includes:
s241: and when the suction parameter is greater than or equal to a first preset threshold value, determining that the tobacco in a section of the cigarette corresponding to the target heating component is consumed.
In some embodiments, when the puff parameter is greater than or equal to a first preset threshold, it is determined that tobacco is depleted in a region of the cigarette corresponding to the target heating assembly. In this real-time example, the first preset threshold corresponds to a nominal suction parameter of the tobacco segment, for example, when the suction parameter is the suction port number, the first preset threshold is the nominal suction port number, and when the suction parameter is the suction duration, the first preset threshold is the nominal suction duration. Thus, the puff parameter can reflect the puff of the user, and then the puff parameter can be compared to a first preset threshold that can reflect the nominal puff of the segment of tobacco, and if the puff parameter is greater than or equal to the first preset threshold, the segment is depleted of tobacco.
In this embodiment, by setting each heating element 12 to be made of a thermistor material, and combining the feature of air intake in smoking, the smoking action can be detected through resistance change, and the smoking parameter is calculated, and then the smoking parameter is compared with the first preset threshold value, so that whether the tobacco in a section of the cigarette corresponding to the target heating element is consumed or not can be determined, and an additional sensor is not needed, so that the electronic smoking set has a simple structure.
Considering that some users draw cigarettes at intervals, for example, 2 minutes after drawing a mouth, tobacco in a region corresponding to the target heating element is still baked and is consumed in small amounts during the interval period, in this case, in order to make the determination of whether consumption is over accurate, in some embodiments, referring to fig. 6, the method further includes:
s26: a cumulative heating time of the target heating assembly is obtained.
S27: and if the accumulated heating time is greater than or equal to a second preset threshold, determining that the tobacco consumption in a section of the cigarette corresponding to the target heating component is depleted.

And taking the accumulated heating time as an evaluation standard, wherein the second preset threshold value is a time threshold value reflecting that the cigarette section can be baked, and if the accumulated heating time is greater than or equal to the second preset threshold value, determining that the tobacco consumption in a section of the cigarette corresponding to the target heating component is depleted.
In this real-time example, the accumulated heating time is used as an evaluation criterion, so that the tobacco in a section of area corresponding to the target heating component is still baked in an interval stage, and errors caused by small consumption of tobacco can be avoided, so that judgment is more accurate, and further, the heating of the section is more sensitive.

In this embodiment, the accumulated heating time and the real-time heating power are integrated to obtain the accumulated heating energy consumed for heating the cigarette segment. The third preset threshold is the energy required by the baking of the tobacco in a section of the tobacco corresponding to the target heating component. And when the heating energy is greater than or equal to a third preset threshold value, determining whether the tobacco in a section of the cigarette corresponding to the target heating component is consumed or not.
In some embodiments, the heating assembly comprises at least two electrical conductors distributed along the circumference of the ceramic tube. It is understood that any two conductors of the at least two conductors form a capacitor, when the cigarette is not inserted, the medium in the middle of the capacitor is ceramic and air, and when the cigarette is inserted into the ceramic tube, the medium in the middle of the capacitor comprises ceramic and the cigarette, and the medium changes, so that the capacitance value of the capacitor can also be caused to change.

For the safety of the smoking set, when the insertion of the cigarettes into the ceramic tube is detected, the cigarettes are preheated, namely, the heating assemblies are controlled to heat, so that the cigarettes are heated to the smoking temperature by the infrared radiation generated by the ceramic tube. When the cigarettes are detected to move out of the ceramic tube, each heating component is controlled to stop heating. Thus, abnormal empty heating of the smoking set can be prevented.
