Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0031] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0032] refer to Figure 1 The present embodiment provides a heating control system for a heating-not-burning appliance, comprising: a first heating structure 10, a second heating structure 20, a processor 40, and a control switch 50. The first heating structure 10 is electrically connected to the processor 40, and the first heating structure 10 is used to heat in a first heating mode under the control of the processor 40; the second heating structure 20 is electrically connected to the processor 40, and the second heating structure 20 is used to heat in a second heating mode under the control of the processor 40; the control switch 50 is used to receive a user's instruction and send the instruction to the processor 40; the processor 40 is used to start the first heating structure 10 to heat in the first heating mode or start the second heating structure 20 to heat in the second heating mode according to the instruction.

[0033] When the heating control system of this embodiment is used, specifically, the first heating method is different from the second heating method, and / or the hardware structures of the first heating structure 10 and the second heating structure 20 are different. The user selects a matching heating structure according to the specifications of the aerosol generating substrate and inserts the aerosol generating substrate into it, and then sends a heating start instruction to the processor 40 through the control switch 50 according to the start mode of the heating structure, and the processor 40 determines whether to use the first heating structure 10 or the second heating structure 20 to heat the aerosol generating substrate by judging the instruction.

[0034] For example, when the specification of the aerosol generating substrate currently used by the user is the first aerosol generating substrate 60, then the first aerosol generating substrate 60 is inserted into the Figure 1In the first heating structure 10 on the right side of the heating-not-burning device shown, the user sends an instruction to start the first heating structure 10 to the processor 40 through the control switch 50. After receiving the instruction, the processor 40 controls the first heating structure 10 to heat in the first heating mode. Specifically, after the first heating mode is started, the circuit of the first heating structure 10 is turned on, and the processor 40 calls the heating temperature control curve corresponding to the first heating mode (i.e., the first heating temperature control curve) to control the heating structure using two control modes, namely power control and TCR temperature control. Specifically, in the preheating stage, a predetermined preheating total power value is set for full power output, so that the temperature rises faster and the preheating time is as short as possible. When the preheating total power of the preheating stage is reached, the TCR (temperature coefficient of resistance) temperature control mode is adopted. The TCR value change of the first heating structure 10 is detected in real time to obtain the real-time temperature value change of the first heating structure 10, and the temperature change data is transmitted to the processor 40 for PID processing of three links such as proportion, integration and differentiation. The processed result value is converted into a PWM (pulse width modulation) duty cycle (the ratio of pulse width to pulse period) through a proportional coefficient, so as to accurately control the target temperature we need.

[0035] For another example, when the specification of the aerosol generating substrate currently used is the second aerosol generating substrate 70, then the second aerosol generating substrate is inserted into Figure 1 In the second heating structure 20 on the left side of the heating-not-burning appliance shown, the user sends an instruction to start the second heating structure 20 to the processor 40 through the control switch 50. After receiving the instruction, the processor 40 controls the second heating structure 20 to heat in the second heating mode. Specifically, after the second heating mode is started, the circuit of the second heating structure 20 is turned on, and the processor 40 calls the heating temperature control curve corresponding to the second heating mode (i.e., the second heating temperature control curve) to control the heating structure using two control modes, namely power control and TCR temperature control. Specifically, in the preheating stage, a predetermined preheating total power value is set for full power output, so that the temperature rises faster and the preheating time is as short as possible. When the preheating total power of the preheating stage is reached, the TCR (temperature coefficient of resistance) temperature control mode is adopted. The TCR value change of the second heating structure 20 is detected in real time to obtain the real-time temperature value change of the second heating structure 20, and the temperature change data is transmitted to the processor 40 for PID processing of three links such as proportion, integration and differentiation. The processed result value is converted into a PWM (pulse width modulation) duty cycle (the ratio of pulse width to pulse period) through a proportional coefficient, so as to accurately control the target temperature we need.

[0036] By adopting the above-mentioned heating control method, it is possible to match aerosol generating substrates of different specifications and models. When in use, different heating methods can be switched only by judging the trigger signal through the processor 40, which is easy to carry and easy to use.

[0037] In practical applications, the processor 40 may be a PLC control board. The control switch 50 includes a button 51 and a touch switch 52. The touch switch 52 connects the button 51 and the processor 40. When in use, the user presses the button 51 to activate the touch switch 52, and then the touch switch 52 transmits a signal to the processor 40, thereby transmitting the user's command.

[0038] As a specific example, the processor 40 is used to start the first heating structure 10 to heat in the first heating mode or start the second heating structure 20 to heat in the second heating mode according to the instruction, including:

[0039] When the instruction output by the control switch 50 is a long signal, the processor 40 starts the first heating structure 10 to heat in the first heating mode according to the long signal.

[0040] Specifically, the control switch 50 outputs a long signal to the processor 40 after being long pressed for a preset time. For example, when the first aerosol generating substrate 60 is inserted into the first heating structure 10, the button 51 is long pressed for 2 seconds, and the touch switch 52 outputs a field signal "1" to the processor 40. The processor 40 determines that the first heating structure 10 needs to be started according to the level signal "1" and heats in the first heating mode. At this time, the circuit of the second heating structure 20 is disconnected, and the circuit of the first heating structure 10 is turned on.

[0041] When the instruction output by the control switch 50 is a short signal, the processor 40 starts the second heating structure 20 to perform heating in the second heating mode according to the short signal.

[0042] Specifically, the control switch 50 outputs a short signal to the processor 40 after being pressed quickly for a preset number of times. For example, when the second aerosol generating matrix 70 is inserted into the second heating structure 20, the button 51 is pressed quickly four times, and the touch switch 52 outputs a continuous short signal "0" to the processor 40. The processor 40 determines that the second heating structure 20 needs to be started at this time according to the length and density of the level signal "0", and heats in the second heating mode. Similarly, at this time, the circuit of the first heating structure 10 is disconnected, and the circuit of the second heating structure 20 is turned on.

[0043] It should be noted that the first aerosol generating substrate 60 and the second aerosol generating substrate 70 in this embodiment are aerosol generating substrates of two different specifications.

[0044] Furthermore, the first heating structure 10 includes: a first heating chamber 11 and a heating rod 12; the heating rod 12 is arranged at the center of the first heating chamber 11, and the heating rod 12 is used to perform central heating on the aerosol generating matrix after receiving the instruction of the processor 40.

[0045] In practical applications, the first heating structure 10 includes a first heating chamber 11 and a heating rod 12. Specifically, the heating rod 12 is disposed inside the first heating chamber 11 and is located at the center of the first heating chamber 11. As a specific example, the diameter of the heating rod 12 is generally set at 2-2.4 mm, the inner diameter of the first heating chamber 11 is generally set at 7.3-7.5 mm, and the length of the heating rod 12 is generally set at 19-20 mm. When the first aerosol generating substrate 60 is inserted into the first heating chamber 11, the heating rod 12 is inserted into the interior of the aerosol generating substrate to achieve central heating of the aerosol generating substrate.

[0046] Furthermore, the second heating structure 20 includes: a second heating chamber 21 and a heating tube 22; the heating tube 22 is circumferentially arranged in the second heating chamber 21, and the heating tube 22 circumferentially heats the aerosol generating substrate after receiving the instruction of the processor 40.

[0047] In practical applications, the second heating structure 20 includes a second heating chamber 21 and a heating tube 22. Specifically, the heating tube 22 is circumferentially arranged inside the second heating chamber 21, so that the outer wall of the heating tube 22 and the inner wall of the second heating chamber 21 can be fitted together to ensure the stability of the installation. When the second aerosol generating substrate 70 is inserted into the second heating chamber 21, the second aerosol generating substrate 70 is also located inside the heating tube 22, and the circumferential heating of the second aerosol generating substrate 70 is achieved through the heating tube 22.

[0048] In some embodiments, the heating control system further includes a display structure 30 , which is electrically connected to the processor 40 , and is used to display the heating mode of the heating structure currently activated by the processor 40 .

[0049] As a further improvement, in order to facilitate the user to grasp the current use status of the heat-not-burn device at any time, a display structure 30 is set on the side of the heat-not-burn device, wherein the display structure 30 can be a display screen. When the processor 40 determines that the first heating structure 10 needs to be started at this time according to the level signal "1" and heating is performed in the first heating mode, the display screen will display an "H" symbol, indicating that the heat-not-burn device is heating the aerosol-generating substrate in a central heating mode at this time.

[0050] When the processor 40 determines, based on the length and density of the level signal "0", that it is necessary to start the second heating structure 20 and perform heating in the second heating mode, the display screen will display the "E" symbol, indicating that the heating non-combustion device is currently heating the aerosol generating substrate in a circumferential heating mode.

[0051] refer to Figure 2 The present embodiment provides a heating control method for a heating-not-burning appliance, which adopts the heating control system as described above. Specifically, the heating control method comprises the following steps:

[0052] Step 100: receiving a user's instruction to start heating;

[0053] Step 200: starting the first heating mode or the second heating mode according to the instruction;

[0054] Step 300: when the first heating mode is started, the first heating structure 10 is controlled to heat in the first heating mode;

[0055] Step 400: When the second heating mode is activated, the second heating structure 20 is controlled to perform heating in the second heating mode.

[0056] When the heating control method of this embodiment is used, the user selects a matching heating structure according to the specifications of the aerosol generating substrate and inserts the aerosol generating substrate therein. Then, according to the starting method of the heating structure, the user controls the switch 50 to send a heating start instruction to the processor 40. The processor 40 determines whether to use the first heating structure 10 or the second heating structure 20 to heat the aerosol generating substrate by judging the instruction.

[0057] For example, when the specification of the aerosol generating substrate currently used by the user is the first aerosol generating substrate 60, then the first aerosol generating substrate 60 is inserted into the Figure 1In the first heating structure 10 on the right side of the heating-not-burning device shown, the user sends an instruction to start the first heating structure 10 to the processor 40 through the control switch 50. After receiving the instruction, the processor 40 controls the first heating structure 10 to heat in the first heating mode. Specifically, after the first heating mode is started, the circuit of the first heating structure 10 is turned on, and the processor 40 calls the heating temperature control curve corresponding to the first heating mode (i.e., the first heating temperature control curve) to control the heating structure using two control modes, namely power control and TCR temperature control. Specifically, in the preheating stage, a predetermined preheating total power value is set for full power output, so that the temperature rises faster and the preheating time is as short as possible. When the preheating total power of the preheating stage is reached, the TCR (temperature coefficient of resistance) temperature control mode is adopted. The TCR value change of the first heating structure 10 is detected in real time to obtain the real-time temperature value change of the first heating structure 10, and the temperature change data is transmitted to the processor 40 for PID processing of three links such as proportion, integration and differentiation. The processed result value is converted into a PWM (pulse width modulation) duty cycle (the ratio of pulse width to pulse period) through a proportional coefficient, so as to accurately control the target temperature we need.

[0058] For another example, when the specification of the aerosol generating substrate currently used by the user is the second aerosol generating substrate 70, then the second aerosol generating substrate is inserted into the aerosol generating substrate. Figure 1 In the second heating structure 20 on the left side of the heating-not-burning appliance shown, the user sends an instruction to start the second heating structure 20 to the processor 40 through the control switch 50. After receiving the instruction, the processor 40 controls the second heating structure 20 to heat in the second heating mode. Specifically, after the second heating mode is started, the circuit of the second heating structure 20 is turned on, and the processor 40 calls the heating temperature control curve corresponding to the second heating mode (i.e., the second heating temperature control curve) to control the heating structure using two control modes, namely power control and TCR temperature control. Specifically, in the preheating stage, a predetermined preheating total power value is set for full power output, so that the temperature rises faster and the preheating time is as short as possible.

The processed result value is converted into a PWM (pulse width modulation) duty cycle (the ratio of pulse width to pulse period) through a proportional coefficient, so as to accurately control the target temperature we need.

[0059] By adopting the above-mentioned heating control method, it is possible to match aerosol generating substrates of different specifications and models. When in use, different heating methods can be switched only by judging the trigger signal through the processor 40, which is easy to carry and easy to use.
