[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] In some embodiments, the present application provides a control method for a heat-not-burn appliance, which is used to control the heating of the heat-not-burn appliance. Among them, the heat-not-burn appliance refers to an appliance that atomizes an aerosol-generating substrate into an aerosol by heating rather than direct combustion. In the present application, the heat-not-burn appliance may be provided with a circumferential heating component, which refers to a component that can heat and bake the aerosol-generating substrate along the circumference of the aerosol-generating substrate. It may include at least one heating circuit, and the heating circuit may be arranged along the circumference of the aerosol-generating substrate to achieve circumferential heating.

[0054] It is understood that the component structure of the circumferential heating component, the arrangement structure of the heating circuit, etc. can be determined according to actual conditions, and this application does not impose specific restrictions on this. In one example, the circumferential heating component can be implemented using a ceramic heating tube, that is, at least one section of the heating circuit is arranged on the surface of the ceramic thick film tube to avoid magnetic field shielding inside the heating chamber.

[0055] In one example, a heat-not-burn appliance may be Figure 1As shown, it includes: an upper cover 102, a ceramic heating tube 103, a heating circuit lead 104, a metal sheet 105, a base 106 and a heating circuit 107. The heating circuit 107 can be arranged on the surface of the ceramic heating tube 103 and form a circumferential heating component together with the ceramic heating tube 103. When the aerosol generating substrate 101 (such as a cigarette) is inserted into the heat-not-burn device, the heat-not-burn device can circumferentially heat the aerosol generating substrate through the circumferential heating component to atomize the aerosol generating substrate into an aerosol.

[0056] In one example, the circumferential heating assembly may include two heating circuits, and the two heating circuits may be arranged in accordance with Figure 2 The arrangement schematic diagram shown is arranged on the surface of the ceramic heating tube 103 .

[0057] In order to realize the intelligent control function of the heating without burning appliance, the heating without burning appliance may also be provided with a control component. It is understood that the control component may be a component with a data processing function. It should be noted that in addition to the data processing function, the control component may also have more functions, such as an electrical parameter detection function, etc., and its specific implementation may be determined according to actual conditions, and this application does not impose specific restrictions on this.

[0058] The control component can be regarded as the signal processing center of the heat-not-burn appliance, which is used to realize data acquisition function and / or control other components. For example, the control component can realize heating control by controlling the electrical parameter value (such as resistance value, voltage value, current value, power value, etc.) of the circumferential heating component, thereby controlling the heating temperature of the circumferential heating component.

[0059] It should be noted that, in addition to the components mentioned above, the heat-not-burn device may also include more components, such as a nozzle, a liquid storage tank, a power supply component, a prompt component, etc. The heat-not-burn device involved in this application may be a device of any shape, any principle, and any structure, and this application does not make any specific restrictions on this, as long as it has at least a circumferential heating component and a control component.

[0060] In some embodiments, the present application provides a control method for a heating-not-burning appliance. The following embodiments are described by taking the application of the method to a control component as an example. Figure 3 As shown, the control method of the heating-not-burning appliance of the present application may include the following steps:

[0061] S302: in response to the arrival of the current cycle, perform electrical parameter detection on the heating circuit and obtain the current electrical parameter value;

[0062] S304: Calculating the target electrical parameter change value corresponding to the heating circuit in the current cycle according to the current electrical parameter value when the preset difference calculation rule is met;

[0063] S306: If the preset insertion judgment rule is met, data matching is performed in at least one first preset relationship according to the target electrical parameter change value, and a matching result is determined; wherein the first preset relationship is a correspondence relationship between the electrical parameter change value of the heating circuit and the substrate type of the aerosol generating substrate;

[0064] S308: If the matching result is the target substrate type, the circumferential heating component is heated and controlled according to the target substrate type.

[0065] Specifically, since there is a soft magnetic material inside the aerosol generating matrix, when the aerosol generating matrix is ​​inserted into / pulled out of the heating without burning device, the magnetic flux inside the heating chamber will change, causing the electrical parameter value of the heating circuit distributed on the outer surface of the heating chamber to change accordingly. At the same time, considering that different types of aerosol generating matrices contain different soft magnetic materials, if different types of aerosol generating matrices are inserted into the heating without burning device respectively, the change in magnetic flux inside the heating chamber will also be different. Based on this principle, the present application can realize the control of the heating without burning device according to the electrical parameter value of the heating circuit.

[0066] When the current cycle arrives, the control component can detect the electrical parameters of the heating circuit to obtain the current electrical parameter value. It can be understood that the current electrical parameter value refers to the electrical parameter value of the heating circuit in the current cycle. The electrical parameter value described in this application can be, but is not limited to, voltage value, current value, inductance value, etc. For ease of description, some embodiments below are described using inductance value as an example.

[0067] In one example, if the circumferential heating assembly includes multiple heating circuits, the control assembly may select one or more of the heating circuits for electrical parameter detection. If multiple heating circuits are selected for electrical parameter detection, the control assembly may measure the electrical parameter value corresponding to each heating circuit in the current cycle, and perform weighted summation of the electrical parameter values ​​of each heating circuit to obtain the current electrical parameter value.

[0068] When the electrical parameter value of the heating circuit in the current cycle is obtained, if the preset difference calculation rule is met, the control component can calculate the target electrical parameter change value corresponding to the heating circuit in the current cycle according to the current electrical parameter value, and the target electrical parameter change value is used to reflect the degree of change of the electrical parameter value of the heating circuit. For example, when the difference calculation rule is met, the control component can subtract the electrical parameter value obtained by the previous cycle detection from the current electrical parameter value to obtain the target electrical parameter change value.

[0069] Among them, the difference calculation rule refers to the rule used to determine whether it is necessary to calculate the change in electrical parameters. The content of the rule can be predetermined based on actual conditions such as electrical parameter detection accuracy and control accuracy requirements, and this application does not impose specific restrictions on this.

[0070] When the target electrical parameter change value is calculated, the control component can determine whether the preset insertion judgment rule is met. Among them, the insertion judgment rule refers to the rule used to determine whether the aerosol generating substrate is inserted into the heating non-combustion device. The specific rule content can be preset according to the actual situation, and the present application does not impose specific restrictions on this. In one example, if the electrical parameter value is an inductance value, the control component can determine whether the aerosol generating substrate is inserted into the heating non-combustion device based on the size relationship between the target electrical parameter change value and the first preset inductance threshold. If the target electrical parameter change value is greater than the first preset inductance threshold, it can be determined that the insertion judgment rule is met, that is, it can be determined that the aerosol generating substrate is inserted into the heating non-combustion device.

[0071] When the insertion judgment rule is met, the control component can perform data matching in at least one first preset relationship according to the target electrical parameter change value. Since the first preset relationship is the corresponding relationship between the electrical parameter value change value of the heating circuit and the substrate type of the aerosol generating substrate, after data matching, the control component can try to determine the substrate type of the aerosol generating substrate inserted into the heat-not-burn appliance and obtain a matching result.

[0072] If the matching result is the target substrate type corresponding to the target electrical parameter change value, it indicates that the inserted aerosol generating substrate is an aerosol generating substrate matched to the heat-not-burn device. In this case, the control component can drive the circumferential heating component according to the target substrate type, so that the circumferential heating component can heat and bake the inserted aerosol generating substrate with a heating temperature that matches the target substrate type, thereby improving the atomization taste.

[0073] Furthermore, in one example, the heat-not-burn appliance may also include a prompt component, which refers to a component in the heat-not-burn appliance that has a prompt function, and may be, but is not limited to, a prompt light, a display screen, a sound device, etc. When the circumferential heating component is driven, the control component may provide a light, display, or vibration prompt through the prompt component.

[0074] In one example, if the matching result is empty, it indicates that the inserted aerosol generating substrate is not suitable for the heat-not-burn appliance. In this case, the control component may not drive the circumferential heating component, and may issue a prompt alarm through the prompt component of the heat-not-burn appliance.

[0075] In some embodiments, Figure 4 As shown, when the preset difference calculation rule is met, the target electrical parameter change value corresponding to the heating circuit in the current cycle is calculated according to the current electrical parameter value, including:

[0076] S402: Calculating a current electrical parameter difference value according to a current electrical parameter value and a reference electrical parameter value; wherein the reference electrical parameter value is an electrical parameter value obtained by performing electrical parameter detection on the heating circuit in a previous cycle;

[0077] S404: If the current electrical parameter difference meets the preset stability judgment threshold, the current electrical parameter value is recorded as the latest stable value, and the target electrical parameter change value is calculated according to the latest stable value and the previous stable value.

[0078] Specifically, during the process of inserting / pulling the aerosol generating substrate into / out of the heat-not-burn device, the electrical parameter values ​​of the heating circuit show a trend of gradual change over multiple cycles until the aerosol generating substrate is fully inserted / pulled out. When the aerosol generating substrate is fully inserted / pulled out, the electrical parameter values ​​of the heating circuit tend to be stable.

[0079] For example, during the process of inserting the aerosol generating substrate into the heat-not-burn device, the inductance value of the heating circuit will gradually increase over multiple cycles until the aerosol generating substrate is completely inserted. For another example, during the process of removing the aerosol generating substrate from the heat-not-burn device, the inductance value of the heating circuit will gradually decrease over multiple cycles until the aerosol generating substrate is completely removed.

[0080] Based on this, in order to accurately calculate the electrical parameter change value of the heating circuit to improve the control reliability of the heating-not-burning appliance, in this embodiment, the control component can compare the electrical parameter value detected in the current cycle with the electrical parameter value detected in the previous cycle to determine whether the electrical parameter value of the heating circuit has stabilized. If so, the target electrical parameter change value corresponding to the heating circuit in the current cycle is calculated.

[0081] Specifically, the control component can use the electrical parameter value of the heating circuit in the previous cycle as the reference electrical parameter value, and subtract the reference electrical parameter value from the current electrical parameter value to obtain the current electrical parameter difference. It can be understood that the current electrical parameter difference is the electrical parameter change of the heating circuit in two adjacent cycles.

[0082] When the current electrical parameter value difference is calculated, the control component can compare the current electrical parameter difference with the preset stability judgment threshold value, and judge whether the electrical parameter value of the heating circuit has tended to be stable in the current cycle. For example, if the current electrical parameter difference is less than the stability judgment threshold value, it can be determined that the electrical parameter value of the heating circuit has tended to be stable in the current cycle, otherwise, it can be determined that the electrical parameter value of the heating circuit is still in a gradual change trend in the current cycle.

[0083] When the current electrical parameter difference meets the stability judgment threshold, the control component can record the current electrical parameter value as the latest stable value, and calculate the difference between the latest stable value and the previous stable value, so as to obtain the target electrical parameter change value.

[0084] Since the electrical parameter values ​​of the heating circuit show a trend of gradual change in multiple cycles during the process of inserting / pulling out the aerosol generating matrix into the heating without burning device, until the aerosol generating matrix is ​​completely inserted / pulled out. Therefore, the previous stable value is the electrical parameter value corresponding to the heating circuit before the aerosol generating matrix is ​​inserted / pulled out. Taking the insertion of the aerosol generating matrix into the heating without burning device as an example, when the aerosol generating matrix is ​​not completely inserted into the heating without burning device, the magnetic flux inside the heating chamber remains unchanged, and the electrical parameter values ​​of the heating circuit show a stable trend. As the aerosol generating matrix is ​​inserted into the heating without burning device, the magnetic flux inside the heating chamber changes continuously, causing the electrical parameter values ​​of the heating circuit to gradually change. When the aerosol generating matrix is ​​completely inserted into the heating without burning device, the magnetic flux inside the heating chamber remains unchanged, and the electrical parameter values ​​of the heating circuit show a stable trend.

[0085] It can be seen that, for the case where the aerosol generating substrate is inserted into the heating without burning device, the latest stable value is the electrical parameter value of the heating circuit when the aerosol generating substrate is fully inserted into the heating without burning device, and the previous stable value is the electrical parameter value of the heating circuit when the aerosol generating substrate is not fully inserted into the heating without burning device. For the case where the aerosol generating substrate is pulled out of the heating without burning device, the latest stable value is the electrical parameter value of the heating circuit when the aerosol generating substrate is fully pulled out of the heating without burning device, and the previous stable value is the electrical parameter value of the heating circuit when the aerosol generating substrate is fully inserted into the heating without burning device.

[0086] The present application calculates the target electrical parameter change value based on the latest stable value and the previous stable value, so that the target electrical parameter change value can more accurately reflect the electrical parameter change of the heating circuit before and after the aerosol generating matrix is ​​plugged in. Subsequent heating control based on the target electrical parameter change value can further improve the reliability of control.

[0087] In some embodiments, the circumferential heating assembly is controlled to heat according to the target substrate type, including:

[0088] According to the target substrate type, data matching is performed in at least one second preset relationship, and a target temperature curve is determined; wherein the second preset relationship is a correspondence between the substrate type of the aerosol generating substrate and the heating curve;

[0089] The circumferential heating component is heated and controlled so that the circumferential heating component is heated according to a target temperature curve.

[0090] In this embodiment, the control component may pre-store at least one second preset relationship, which refers to the corresponding relationship between the substrate type of the aerosol generating substrate and the heating curve. When the target substrate type is obtained, the control component may determine the target temperature curve corresponding to the target substrate type in each second preset relationship, and drive the circumferential heating component according to the target temperature curve, so that the circumferential heating component heats and bakes the aerosol generating substrate according to the heating temperature change described by the target temperature curve. In this way, the atomization taste can be further improved.

[0091] In some embodiments, the heating control of the circumferential heating assembly is performed according to the target substrate type, further comprising:

[0092] When the circumferential heating component is in the heating state, the heating time is counted;

[0093] In response to the reheating instruction, the circumferential heating assembly is controlled to heat according to the target temperature curve and the heating time.

[0094] In actual scenarios, the circumferential heating component may be interrupted due to factors such as user operation and appliance power. In order to enable the heating-not-burning device to heat and bake the aerosol-generating matrix according to the consumption of the aerosol-generating matrix during reheating after the interruption to further improve the atomization taste, in this embodiment, when the circumferential heating component is in a heating state, the control component can count the cumulative heating time of the circumferential heating component. When receiving a reheating instruction, the control component can heat and drive the circumferential heating component according to the target temperature curve and the heating time.

[0095] For example, the control component may determine a target curve segment in the target temperature curve according to the heating time, and drive the circumferential heating component according to the target curve segment. For another example, the control component may determine a target heating temperature in the target temperature curve according to the heating time, determine a driving energy value according to the target heating temperature, and drive the circumferential heating component according to the driving energy value.

[0096] In some embodiments, heating control of the circumferential heating assembly includes:

[0097] Driving the circumferential heating component to heat the circumferential heating component so that the circumferential heating component is continuously in a heating state until a heating stop condition is met;

[0098] Wherein, satisfying the heating stop condition includes satisfying at least one of the following:

[0099] Satisfy the preset extraction judgment rules;

[0100] The heating time is greater than or equal to the preset time threshold;

[0101] A heating stop instruction input by the user is received.

[0102] In this embodiment, when the target substrate type is matched, the control component can continuously drive the circumferential heating component so that the circumferential heating component is continuously in a heating state and heats and bakes the aerosol generating substrate until the preset unplugging judgment rule is met, the heating time is greater than or equal to the preset time threshold, and / or a heating stop instruction input by the user is received. For example, when it is determined that the unplugging judgment rule is met, the heating time is greater than or equal to the preset time threshold, and / or a heating stop instruction input by the user is received, the control component can stop driving the circumferential heating component to stop heating. In this way, automatic heating stop can be achieved, which can be more intelligent.

[0103] Furthermore, when the circumferential heating component stops driving, the control component can drive the prompt component to provide a light display and vibration prompt to remind the user that the heating has been paused.

[0104] Among them, the extraction judgment rule refers to the rule used to judge whether the aerosol generating substrate is pulled out from the heating without burning appliance. The specific content of the rule can be determined according to the actual situation, and this application does not impose specific restrictions on this. In one example, if the electrical parameter value is an inductance value, the control component can judge whether the aerosol generating substrate is pulled out from the heating without burning appliance based on the magnitude relationship between the target electrical parameter change value and the second preset inductance threshold. If the target electrical parameter change value is less than the second preset inductance threshold, it can be determined that the extraction judgment rule is met, and it can be determined that the aerosol generating substrate has been pulled out from the heating without burning appliance.

[0105] When the heating time is greater than or equal to the preset time threshold, it indicates that the total baking time of the aerosol generating substrate has reached a critical value. If the baking continues, the aerosol generating substrate may release harmful substances. Therefore, when the heating time is greater than or equal to the preset time threshold, the control component can stop driving the circumferential heating component.

[0106] The user can input a heating stop instruction to the heating non-combustion appliance through the buttons, display components, vibration sensors, etc. of the heating non-combustion appliance to instruct the control component to stop driving the circumferential heating component and thus stop heating.

[0107] In some embodiments, the control method of the heating without burning appliance provided in the present application may further include the following steps:

[0108] If the unplugging judgment rule is met, or the heating time is greater than or equal to the preset time threshold, the heating time is reset.

[0109] In this embodiment, when the removal judgment rule is met or the heated time is greater than or equal to the preset time threshold, it indicates that the aerosol generating substrate needs to be replaced. In this case, the control component can perform a zeroing operation on the heated time to ensure that the heated time accurately reflects the cumulative heating time of a single aerosol generating substrate, thereby improving the reliability and accuracy of the control.

The control device of the heating without combustion appliance described below and the control method of the heating without combustion appliance described above can be referred to each other.

[0136] Those skilled in the art will understand that the internal structure of the control component shown in the present application is merely a block diagram of a partial structure related to the scheme of the present application, and does not constitute a limitation on the control component to which the scheme of the present application is applied. The specific control component may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0137] In some embodiments, the present application provides a heating-not-burning appliance, comprising:

[0138] A heating chamber, used to contain an aerosol-generating substrate;

[0139] A circumferential heating assembly includes at least one heating circuit; the heating circuit is arranged along the circumference of the heating chamber for heating;

[0140] The control component described in any of the above embodiments is connected to the at least one heating circuit and is used to execute the steps of the control method of the heating non-combustion appliance described in any of the above embodiments to control the heating of the circumferential heating component.

[0141] For a description of the heating chamber, circumferential heating components, heating circuits and control components, please refer to the above and Figure 1-Figure 4 , this application will not be repeated here.

[0142] In some embodiments, the control component includes: an inductance detection circuit and a control circuit. The inductance detection circuit refers to a circuit for detecting the inductance value of the heating circuit, and can periodically detect the inductance value of the heating circuit to obtain the electrical parameter value of the heating circuit. The control circuit refers to a circuit with a data processing function, and its specific implementation can be determined according to actual conditions, and this application does not impose specific restrictions on this.

[0143] The inductance detection circuit may include a voltage-controlled oscillator unit and a voltage-stabilizing unit, and the voltage-controlled oscillator unit may be connected to the voltage-stabilizing unit and at least one section of the heating circuit, respectively. The voltage-stabilizing unit is used to connect to the power supply component, to stabilize the voltage output by the power supply component, and to provide the stabilized voltage as a working voltage to the voltage-controlled oscillator unit. The control circuit may be connected to the voltage-controlled oscillator unit.

[0144] When the inductance value is different, the oscillation signal output by the voltage-controlled oscillation unit has different frequencies. Therefore, the control circuit can detect the signal frequency of the oscillation signal output by the voltage-controlled oscillation unit and calculate the inductance value of the heating circuit based on the signal frequency.

[0145] In this embodiment, inductance detection is achieved through a voltage-controlled oscillation unit and a voltage stabilization unit, which has the advantages of simple implementation and small size.

[0146] In one example, the circuit structure of the inductance detection circuit can be as follows: Figure 6 As shown, the voltage-controlled oscillation unit is implemented based on the MC1648 chip, and the voltage stabilization unit is implemented based on the 7805 three-terminal voltage stabilization integrated circuit. In this way, the cost of the inductance detection circuit can be reduced. Figure 6 In the figure, Lx is the inductance value of the heating circuit. By connecting the heating circuit to points A and B in the figure and measuring the signal frequency of the signal at point C, the inductance value of Lx can be calculated based on the signal frequency, thereby realizing the inductance detection of the heating circuit.
