In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, an environment for implementing the method for controlling heating of a non-combustible electronic smoking article according to the first embodiment of the present application includes heating of a non-combustible electronic smoking article 100 and a tobacco rod 200. Heating incombustible electron smoking set 100 includes the heating device 101 that a plurality of intervals set up, and a plurality of heating device 101 can be controlled by control module 102 independent control to, can realize carrying out the segmentation heating to a cigarette 200, compare in whole cigarette bulk heating, heating efficiency is more reasonable, can make the smog volume suitable, extension cigarette live time.

Wherein, the tobacco in cigarette 200 is toasted the back by heating device 101, can give off the aerosol, and when the user smoked the cigarette holder of a cigarette 200, the air got into smoking set 100 in, through a cigarette 200, carries the aerosol that gives off after toasting in the cigarette 200 to the user's mouth in for the user inhales.

Referring to fig. 2, a heating non-combustible electronic smoking article 100 is provided according to a second embodiment of the present application, wherein the heating non-combustible electronic smoking article 100 includes an infrared ceramic heating tube 10 and a controller 30. The infrared ceramic heating tube 10 includes a ceramic tube 11 and at least two heating assemblies 12.

The ceramic tube 11 is used for accommodating the cigarette 200. When the ceramic tube 11 is heated, a large amount of infrared rays are excited, and the cigarettes 200 accommodated in the ceramic tube 11 are heated by the infrared rays generated by the excitation. In the embodiment, the infrared rays are not shielded by other media, so that the utilization rate is high, and the heating efficiency is higher.

It will be appreciated that the material of the ceramic tube 11 may be a magnesium hercynite-cordierite composite ceramic. The magnesium-iron-chromium spinel-cordierite composite ceramic is a composite infrared ceramic prepared by adding magnesium-iron-chromium spinel into low-expansion base material cordierite in the form of additive, the infrared radiation efficiency of the composite infrared ceramic can reach 90%, and the structure is stable. Thereby, the ceramic tube 11 is made to have a high infrared radiation efficiency. It can be understood that the wavelength of the infrared ray generated by the ceramic tube 11 matches with the cigarette 200, that is, when the frequency of the infrared ray matches with the molecular vibration frequency of the tobacco in the cigarette 200, the molecular motion of the tobacco in the cigarette 200 is more intense, and thus, the optimal heating effect can be obtained.

At least two heating assemblies 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 is understood that in some embodiments, the heating assembly 10 may be in the form of a conductive paste coating or a heat generating wire. In some embodiments, the conductive paste coating as the heating component may be tungsten-manganese paste, and the like, and is coated on the outer wall or the middle layer of the ceramic tube, so that when the conductive paste coating is electrified, the ceramic tube can be heated. It will be appreciated that for multiple heating assemblies, it may be desirable to apply each conductive paste coating in segments. In some embodiments, a heating wire as the heating component may be wound around an outer wall of the infrared ceramic component, and when the heating wire is powered on, the ceramic tube may be heated.

The heating elements 12 are arranged in sequence along the axial direction of the ceramic tube 11, and one heating element 12 corresponds to one section of the ceramic tube 11, for example, heating element 1# corresponds to section a of the ceramic tube, heating element 2# corresponds to section B of the ceramic tube, and heating element 3# corresponds to section C of the ceramic tube. When a heating element 1# heating, the regional A section of the ceramic pipe that corresponds is heated and produces the infrared ray to carry out sectional type heating to a corresponding regional one section of cigarette, because, other sections of ceramic pipe are not heated, thereby, can not produce the infrared ray, other sections of cigarette can not heat because of receiving infrared radiation.

It will be appreciated that each heating assembly 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 change in resistance of the heating assembly 12, i.e., the change in temperature, and thus the pumping action, may be detected by a corresponding detection circuit.

The controller is respectively connected with each heating component, thereby, can gather each heating component's voltage to control each heating component's heating power. Specifically, the controller may be connected to each of the heating assemblies 12 via a sensing circuit. The detection circuit is used for collecting the voltage and the current at the two ends of each heating assembly in real time and sending the voltage and the current at the two ends to the controller, so that the controller can obtain the resistance according to the voltage and the current at the two ends. It will be appreciated that the controller may also control the heating power of each heating assembly by controlling the respective power supply unit 40.

In the preheating stage, each heating element 12 is controlled to heat by controller 30 to, the whole heating of ceramic pipe 11 produces the infrared ray, and the whole cigarette 200 of infrared radiation heaies up to smoking temperature, and it can be understood that smoking temperature is higher than the temperature that gives out the aerosol with the tobacco baking in the cigarette to prevent that the cigarette temperature can not reach the temperature that gives out the aerosol with the tobacco baking in the cigarette after the air gets into. It is understood that each heating assembly 12 is connected to a power supply unit 40, the power supply unit 40 supplies power to each heating assembly 12, and the power supply unit 40 generally includes various power supply circuits and control circuits, so that the power supply unit 40 can supply power to each heating assembly 12 intermittently under the control of the controller 30, thereby maintaining the temperature of each heating assembly 12 at a preset temperature, for example, by adjusting the duty ratio of the current or voltage output by the power supply unit to each heating assembly 12 to maintain each heating assembly 12 at a preset temperature, so as to heat the ceramic tube 11. Therefore, the ceramic tube 11 can radiate infrared rays with certain energy to heat the cigarette 200, and the temperature of the cigarette 200 is kept to be raised to the smoking temperature. It is understood that controlling the temperature of the heating assembly 12 is equivalent to controlling the baking temperature of the ceramic tube 11 to 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 a section of baked aerosol of the cigarette, at this time, the controller 30 selects any heating assembly from the heating assemblies 12 as a target heating assembly, controls the target heating assembly to continue heating, so that a section of the area of the cigarette 200 corresponding to the target heating assembly is controlled to the smoking temperature, and controls the remaining heating assemblies except the target heating assembly to stop heating. It will be appreciated that the draw temperature is the temperature at which the aerosol of the baked tobacco rod is maintained, and is slightly below the draw temperature. In this embodiment, only one section of the cigarette 200 corresponding to the target heating assembly is baked with aerosol, and other sections of the cigarette 200 are not baked with aerosol, so that the problem of overhigh heating efficiency caused by the integral baking of the cigarette can be avoided.

To enable the cigarettes to be cured in segments, the smoking article 100 should also have the ability to detect the depletion of tobacco in the segment of the cigarette being cured, and when depletion, to initiate the curing of the next segment of the cigarette 200. In conventional solutions, the suction is typically sensed by providing an additional sensor, such as an additional air flow sensor or the like, to compare the number of suction openings with a nominal number of suction openings that can be supplied for the segment of tobacco to determine whether the tobacco has been depleted in the segment being cured.

In this embodiment, the controller 30 determines the puff parameters based on the change in resistance of the remaining heating elements 12, and determines whether the tobacco in the section of the cigarette 200 corresponding to the target heating element is depleted based on the puff parameters without the need for additional sensors. Specifically, as shown in fig. 3, when a user sucks the ceramic tube, the temperature of the ceramic tube 11 is lowered due to the entering of the air flow, the temperature of the remaining heating assemblies made of the thermistor material is also lowered, the resistance of the remaining heating assemblies is changed first, the controller is connected with each heating assembly, the controller can acquire that the resistance of the remaining heating assemblies is changed first, the controller can increase the heating power of the target heating assembly, so that 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 instantly raised to the smoking temperature due to the stop of the air flowing in, the temperature of the remaining heating assemblies is also raised, the resistance of the remaining heating assemblies is changed second, after the controller acquires that the resistance of the remaining heating assemblies is changed second, the controller can reduce the heating power of the target heating assembly, and the temperature of the ceramic tube is pulled back to the suction temperature, the temperature of the remaining heating elements also drops to the pumping temperature, which in turn undergoes a third change in resistance. Therefore, each time a cigarette is smoked, the resistance of the rest heating components can be changed in a first way, a second way and a third way, and the smoking action can be determined according to the change of the resistance of the rest heating components. That is, when the first change, the second change and the third change occur periodically, one pumping action is determined. The number of puffs and the duration of a single puff may reflect the puff parameters used to evaluate the segment of tobacco being smoked. Thus, the smoking parameters may be determined based on the smoking action, and further, it may be determined from the smoking parameters whether the tobacco in the section of the cigarette corresponding to the target heating element has been depleted. A determination is made as to whether tobacco in a section of the cigarette corresponding to the target heating element has been depleted. When depletion has ended, controller 30 selects a heating element from the remaining heating elements 12 as the new target heating element, and begins heating use and monitoring of the next section of cigarette 200. Therefore, cigarette sectional type intelligent heating can be realized, cigarette suction time is prolonged, an additional sensor is not needed, and the structure is simple.

It will 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, an arm (acorn RISC machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components.

In some embodiments, the pumping parameter comprises a pumping port number or a pumping duration, wherein the pumping port number is a number of cycles of the first change, the second change, and the third change in the resistance, and the pumping duration is a duration of time for accumulating the first change to the second change to the third change.

When the suction parameter is the number of suction ports, the number of changes can be defined as the number of suction ports by accumulating the number of changes in the resistance. It is understood that the variation refers to a periodic variation from the first variation to the third variation.

When the pumping parameter is a pumping time period, the change time period may be taken as the pumping time period by accumulating the change time period of the resistance. It is understood that the duration of the change refers to the sum of the individual durations of time between the occurrence of the first change to the second change to the third change in resistance.

In some embodiments, when the puff parameter is greater than or equal to a first predetermined threshold, it is determined that the tobacco in a section of the cigarette corresponding to the target heating element is depleted. In this real-time example, the first predetermined threshold corresponds to a rated suction parameter of the cigarette segment, for example, when the suction parameter is the number of suction openings, the first predetermined threshold is the rated number of suction openings, and when the suction parameter is the suction duration, the first predetermined threshold is the rated suction duration. The puff parameter is then compared to a first predetermined threshold value that reflects a nominal puff volume of the tobacco in the segment, and if the puff parameter is greater than or equal to the first predetermined threshold value, it indicates that the tobacco in the segment has been depleted.

In this embodiment, each heating element 12 is made of a thermistor material, and in combination with the characteristics of air entering during smoking, the smoking action can be detected through the resistance change, the smoking parameters are calculated, and then the smoking parameters are compared with a first preset threshold value, so that whether the tobacco in a section of area corresponding to the target heating element in the cigarette is consumed completely or not can be determined, and no additional sensor is needed, so that the electronic smoking set is simple in structure.

Considering that some users may smoke cigarettes at intervals, for example, every 2 minutes after a puff, and then smoke, and during the interval period, the tobacco in the section of area corresponding to the target heating assembly is still roasted, and the tobacco is also consumed a little, in this case, in order to make the determination result of the consumption of tobacco to be used up accurate, in some embodiments, the step of determining, by the controller, whether the tobacco in the section of area corresponding to the target heating assembly is used up further includes:

acquiring the accumulated heating time of the target heating assembly;

and if the accumulated heating time is greater than or equal to a second preset threshold value, determining that the tobacco in a section of the cigarette corresponding to the target heating assembly is depleted.

Wherein, the accumulated heating time refers to the total time for which the tobacco in a section corresponding to the target heating component is accumulated and roasted. With the accumulative heating time as the evaluation criterion, the time threshold that the second preset threshold can receive the toast for reflecting the cigarette section, accumulative heating time is greater than or equal to the second preset threshold, then confirms in the cigarette props up with the tobacco in the section region that the target heating subassembly corresponds is consumed totally.

In this real-time example, the accumulated heating time is used as an evaluation standard, so that the error caused by the fact that the tobacco in a section of area corresponding to the target heating assembly is still baked and a small amount of tobacco is consumed can be avoided at the interval stage, the judgment is more accurate, and the sectional heating is more sensitive.

In some embodiments, the step of determining whether the tobacco in the segment of the area corresponding to the target heating element is depleted further comprises:

In this embodiment, the accumulated heating time and the real-time heating power are integrated to obtain the accumulated heating energy consumed by heating the smoke branch section. The third preset threshold is the energy required for finishing the baking of the tobacco in a section of area corresponding to the target heating assembly in the cigarette. When the accumulated heating energy is greater than or equal to a third preset threshold value, determining that the tobacco consumption in a section of area corresponding to the target heating assembly in the cigarette is almost exhausted

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, 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, and thus, the capacitance value of the capacitor also changes. Based on the above principle, after acquiring the capacitance between any two of the at least two conductors, the controller 30 may determine that the cigarette is inserted into or removed from the ceramic tube according to the change of the capacitance.

For the safety of the smoking set, when the cigarette is inserted into the ceramic tube, preheating is started, namely, each heating assembly is controlled to heat, so that the cigarette is heated to the smoking temperature by the infrared radiation generated by the ceramic tube. And when the cigarette is detected to move out of the ceramic tube, controlling each heating assembly to stop heating. Thus, abnormal empty heating of the smoking set can be prevented.

In some embodiments, the infrared ceramic heating tube further includes a heat insulation assembly (not shown) which is sleeved on the outer wall of the ceramic tube 11 and wraps the heating assemblies 12 for keeping the temperature, preventing heat from dissipating, and preventing a user from being scalded. It is understood that the insulation assembly may be made of an alumina composite based porous ceramic or like insulating material.

It is worth noting that the heated non-burning e-cig shown in fig. 2 only shows the components relevant to the present embodiment. Accordingly, one of ordinary skill in the art to which the present embodiment relates will appreciate that the heated non-burning e-smoking article may include conventional components in addition to those shown in fig. 2.

To sum up, the heating non-combustion electronic smoking set that this application embodiment provided includes infrared ceramic heating pipe and controller, and infrared ceramic heating pipe includes ceramic pipe and two at least heating element, and the controller is connected with each heating element respectively. Wherein, 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, one heating component corresponds to one section of area 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 the infrared radiation generated by the ceramic tube, then, the target heating component is controlled to continue heating so that the section of area corresponding to the target heating component in the cigarettes is controlled to the smoking temperature, and the rest heating components are controlled to stop heating, when a user sucks the cigarettes, the temperature of the ceramic tube is instantly reduced due to the entering of air flow, the temperature of the rest heating components made of thermistor materials is also reduced, the resistance of the rest heating components is changed along with the temperature, and the controller can increase the heating power of the target heating component because the controller is connected with each heating component, the controller can acquire the first change of the resistance of the rest heating components, the temperature of the ceramic tube is rapidly increased back to the smoking temperature, when smoking is stopped, air stops flowing in, the temperature of the ceramic tube can be instantly increased to the smoking temperature, the temperature of the rest heating assemblies is increased accordingly, the resistance of the rest heating assemblies is changed secondarily, after the controller obtains that the resistance of the rest heating assemblies is changed secondarily, the controller can reduce the heating power of the target heating assembly, the temperature of the ceramic tube can be pulled back to the smoking temperature, the temperature of the rest heating assemblies is reduced to the smoking temperature accordingly, and the resistance of the rest heating assemblies is changed thirdly accordingly. Therefore, each time a cigarette is smoked, the resistance of the remaining heating assemblies changes by the first change, the second change and the third change, the smoking action can be determined according to the change of the resistance of the remaining heating assemblies, the smoking parameters can be determined, 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 smoking parameters; when the consumption is over, a heating element is selected from the remaining heating elements as a new target heating element, and the heating application of the next section of cigarettes is started. Therefore, cigarette sectional type intelligent heating can be realized, cigarette suction time is prolonged, an additional sensor is not needed, and the structure is simple.

The third embodiment of the present application provides a method of control heating incombustible electronic smoking set, can be applied to any suitable heating incombustible electronic smoking set, and this heating incombustible electronic smoking set infrared ceramic heating pipe, infrared ceramic heating pipe includes ceramic pipe and two at least heating element, wherein, the ceramic pipe is used for acceping a cigarette, two at least heating element set up in on the ceramic pipe, two at least heating element follow the ceramic pipe axial is arranged in proper order, one heating element corresponds one section region of ceramic pipe, two at least heating element are made by thermistor material, and resistance changes along with temperature change promptly, for example, heating element's temperature is higher, and its resistance value is bigger. Therefore, the resistance value of the heating component can be detected through the corresponding detection circuit, and the temperature change can be detected.

When the heating component is electrified and heated, a section of corresponding area of the ceramic pipe is heated to generate infrared rays, so that the corresponding section of area of the cigarette is heated in a sectional mode.

As shown in fig. 4, the method S20 includes:

s21: and controlling the at least two heating components to heat so that the cigarettes are heated to the smoking temperature by the infrared radiation generated by the ceramic tube.

S25: and when the tobacco in the cigarette is consumed up in the section of area corresponding to the target heating component, selecting a heating component from the rest heating components as a new target heating component, and returning to the step S22.

In the preheating stage, each heating element of control heats to, the whole infrared ray that is heated production of ceramic pipe, the whole cigarette of infrared radiation heaies up to smoking temperature, and it can be understood that smoking temperature is the temperature that can give out the aerosol with the tobacco baking in the cigarette. It is understood that each heating assembly is connected to a power supply unit, the power supply unit supplies power to each heating assembly, and the power supply unit generally includes various power supply circuits and control circuits, so that the power supply unit can supply power to each heating assembly intermittently, thereby maintaining the temperature of each heating assembly at a preset temperature, for example, by adjusting the duty ratio of the current or voltage output by the power supply unit to each heating assembly, so as to heat the ceramic tube. Therefore, the ceramic tube can radiate infrared rays with certain energy to heat the cigarettes and keep the temperature of the cigarettes raised to the smoking temperature. It will be appreciated that controlling the temperature of the heating assembly is equivalent to controlling the baking temperature of the ceramic tube against the tobacco rod.

When the temperature of the cigarette reaches the smoking temperature, a smoking stage is entered, and in the stage, a user needs to smoke a section of the baked aerosol of the cigarette, at the moment, any heating assembly is selected from the heating assemblies as a target heating assembly, the target heating assembly is controlled to continue heating, so that a section of area corresponding to the target heating assembly in the cigarette is controlled to the smoking temperature, and the rest heating assemblies except the target heating assembly are controlled to stop heating. In this embodiment, only one section region of the cigarette that the target heating assembly corresponds is toasted aerosol, and other regional sections are not toasted aerosol to, can avoid leading to the heating efficiency too high because of a cigarette whole toasts, in this embodiment, the segmentation is toasted, can satisfy the cigarette volume, can also prolong a cigarette smoking time.

In order to provide for the continuous baking of segments of a cigarette, the smoking article should also have the ability to detect the depletion of tobacco in the segment of the cigarette being baked, and when depletion, the baking of the next segment of the cigarette is initiated. In conventional solutions, the suction is typically sensed by providing an additional sensor, such as an additional air flow sensor or the like, to compare the number of suction openings with a nominal number of suction openings that can be supplied for the segment of tobacco to determine whether the tobacco has been depleted in the segment being cured.

In this embodiment, the smoking parameters are determined based on the change in resistance of the remaining heating elements, and from this smoking parameters it is determined whether the tobacco in the section of the cigarette corresponding to the target heating element has been depleted, without the need for additional sensors. Specifically, as shown in fig. 3, when a user sucks the ceramic tube, the temperature of the ceramic tube is lowered due to the entering of the air flow, the temperature of the remaining heating assembly made of the thermistor material is also lowered, the resistance of the remaining heating assembly is changed accordingly, the heating power of the target heating assembly is increased to rapidly raise the temperature of the ceramic tube to the smoking temperature, when the suction is stopped, the temperature of the ceramic tube is instantly raised to the smoking temperature due to the stop of the air flowing in, the temperature of the remaining heating assembly is also raised accordingly, the resistance of the remaining heating assembly is changed accordingly, the heating power of the target heating assembly is reduced after the resistance of the remaining heating assembly is changed accordingly, the temperature of the ceramic tube is pulled back to the suction temperature, and the temperature of the remaining heating assembly is lowered accordingly to the suction temperature, a third change in resistance follows. Therefore, each time a cigarette is smoked, the resistance of the rest heating components can be changed in a first way, a second way and a third way, and the smoking action can be determined according to the change of the resistance of the rest heating components. That is, when the first change, the second change and the third change occur periodically, one pumping action is determined. The number of puffs and the duration of a single puff may reflect the puff parameters used to evaluate the segment of tobacco being smoked. Thus, the smoking parameters may be determined based on the smoking action, and further, it may be determined based on the smoking parameters whether the tobacco in the section of the cigarette corresponding to the target heating element has been depleted. A determination is made as to whether tobacco in a section of the cigarette corresponding to the target heating element has been depleted. When the consumption is exhausted, a heating assembly is selected from the rest heating assemblies as a new target heating assembly, and heating use and monitoring of the next section of the cigarette are started. Therefore, cigarette sectional type intelligent heating can be realized, cigarette suction time is prolonged, an additional sensor is not needed, and the structure is simple.

When the consumption is almost exhausted, selecting a heating assembly from the rest heating assemblies as a new target heating assembly, starting heating use and monitoring of the next section of the cigarette, namely returning to the step S22, heating the corresponding section in the cigarette through the new target heating assembly, simultaneously monitoring whether the tobacco in the section is completely consumed, if so, selecting a heating assembly from the rest heating assemblies as a new target heating assembly until all the sections in the cigarette are completely consumed, and stopping the operation of the smoking set at the moment.

Therefore, cigarette sectional type intelligent heating can be realized, cigarette suction time is prolonged, an additional sensor is not needed, and the structure is simple.

S29: and if the accumulated heating energy is larger than or equal to a third preset threshold value, determining whether the tobacco in a section of area corresponding to the target heating assembly in the cigarette is depleted.

In this embodiment, the accumulated heating time and the real-time heating power are integrated to obtain the accumulated heating energy consumed by heating the smoke branch section. The third preset threshold is the energy required for finishing the baking of the tobacco in a section of area corresponding to the target heating assembly in the cigarette. And when the heating energy is greater than or equal to a third preset threshold value, determining whether the tobacco in the section of the cigarette corresponding to the target heating assembly is depleted.

In some embodiments, the heating assembly comprises at least two electrical conductors distributed along the circumference of the ceramic tube. It can be understood that any two of the at least two electric 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 is changed, so that the capacitance value of the capacitor is also changed.
