[0002] Heat-not-burn (HnB) technology is a new type of aerosol substrate treatment method, which releases aerosols by heating the aerosol substrate instead of burning it. This method aims to reduce the harmful substances produced by traditional burning aerosol substrates.

[0052] Reference Figure 1 , showing a schematic diagram of a heating without burning device provided in an embodiment of the present application; the embodiment of the present application relates to Figure 1 The split type heating without burning appliance shown in the figure comprises a control unit and an atomizing unit. The control unit transmits signals to the atomizing unit by wire or wirelessly.

[0053] The technical solution of the present application is described below through specific embodiments.

[0054] Reference Figure 2, showing a schematic diagram of a heating control method provided by an embodiment of the present application, the method is applied to a control unit in a heat-not-burn device, the control unit and the atomization unit transmit signals via wired or wireless means; the atomization unit is used to contain an aerosol matrix;

[0055] In the case of transmitting signals in a wired manner, the embodiment of the present application does not limit the connection components between the control unit and the atomization unit, and the connection components may include but are not limited to terminals and wires. For example, the control unit and the atomization unit may have terminals that match each other, and the control unit and the atomization unit may be contacted and connected through the terminals that match each other and transmit signals, so as to realize wired signal transmission between the control unit and the atomization unit.

[0056] In the case of wireless signal transmission, the embodiment of the present application does not limit the signal type of wireless transmission between the control unit and the atomization unit, and the signal type of wireless transmission may include but is not limited to infrared signals, Bluetooth signals, and Wi-Fi (Wireless Fidelity) signals. For example, a first wireless signal device (such as an infrared signal device) may be provided in the control unit, and a second wireless signal device may be provided in the atomization unit, and signal transmission may be performed between the first wireless signal device and the second wireless signal device, so as to realize wireless signal transmission between the control unit and the atomization unit.

[0057] The embodiment of the present application may specifically include the following steps:

[0058] Step 201, determining temperature change information corresponding to the atomization unit;

[0059] The control unit may determine the temperature change information corresponding to the atomizing unit after detecting the heating start operation event. The heating start operation event may be used to characterize the user's operation on the heat-not-burn appliance, for example, clicking a first control set on the heat-not-burn appliance. As an example, the first control may be a press control or a touch control.

[0060] The control unit is adapted to different atomization units. Different atomization units may have different heating methods (e.g., central heating, circumferential heating) or different heating elements, or may heat different aerosol matrices. Different aerosol matrices may include, but are not limited to, different aerosols released after the aerosol matrices are heated, different physical states of the aerosol matrices (e.g., solid or liquid), and different specifications of the aerosols.

[0061] When the control unit is connected to the atomization unit by wire or wirelessly, the control unit may determine the temperature change information matching the currently connected atomization unit.

[0062] As an example, the control unit can identify different atomization units, the control unit can store temperature change information of various identifiable atomization units, and the control unit can read the temperature change information corresponding to the atomization unit currently connected to it.

[0063] As another example, the temperature change information is pre-stored in the atomizing unit, and the control unit receives the temperature change information stored in the currently connected atomizing unit. For example, when the atomizing unit is manufactured, the temperature change information is stored in the atomizing unit through a designated device.

[0064] Step 202, generating heating control information according to the temperature change information;

[0065] The temperature change information is used to characterize the heating method of the corresponding aerosol substrate, such as the required temperature, heating time, etc. The control unit generates heating control information according to the temperature change information corresponding to the currently connected atomization unit, so that when the atomization unit heats the aerosol substrate according to the heating control information, the temperature change of the aerosol substrate matches the temperature change information.

[0066] Step 203: Send the heating control information to the atomization unit to instruct the atomization unit to heat the aerosol matrix according to the heating control information.

[0067] After generating the heating control information, the control unit sends the heating control information to the atomization unit, and the atomization unit is used to control its own heating element to work by using the heating control information, so as to heat the aerosol matrix through the heating element and release the aerosol.

[0068] It is understandable that since the heating of the aerosol substrate by the atomization unit is a continuous process, in the embodiment of the present application, the control unit may repeatedly perform step 202 at a specified frequency, so that the heating control information may be periodically sent to the atomization unit at the specified frequency. The atomization unit heats the aerosol substrate according to the most recently received heating control information.

[0069] In an embodiment of the present application, the temperature change information corresponding to the atomization part is determined; heating control information is generated based on the temperature change information; the heating control information is sent to the atomization part to instruct the atomization part to heat the aerosol matrix based on the heating control information; the heating control information is generated based on the predetermined temperature change information; the atomization part controls the heating of the heating element based on the heating control information; since the heating control information generation process is decoupled from the resistance value of the connection position between the control part and the atomization part, the resistance value of the connection position between the control part and the atomization part can be prevented from affecting the heating of the heating element; the atomization part controls the heating of the heating element based on the heating control information, thereby improving the accuracy of the heating temperature control of the heating element.

[0070] In some implementations of the embodiments of the present application, the temperature change information includes an initial heating temperature and a time-temperature change curve; step 202 may include: using the initial heating temperature to generate heating control information; calculating the heated time, and determining the position of the heated time on the time-temperature change curve as a time node, and a node temperature corresponding to the time node; if the node temperature of the current time node is inconsistent with the node temperature of the previous time node, using the target temperature to generate the heating control information; the target temperature is the node temperature corresponding to the current time node.

[0071] When the heating element starts to be heated, heating control information is generated according to the preheating temperature, so that the atomization unit controls the heating element to be heated to the preheating temperature, and then the aerosol matrix is ​​heated to the preheating temperature through the heating element.

[0072] After the heating control information is generated, the current heating time is calculated. The time-temperature change curve included in the temperature change information refers to a curve for controlling the temperature of the aerosol substrate releasing aerosols over time. Each position on the time-temperature change curve corresponds to a continuous time node, and each time node corresponds to a predetermined temperature.

[0073] After determining the heated time, the current time node where the current heated time is located on the time-temperature variation curve can be determined, and the temperature corresponding to the current time node obtained at the adjacent time can be used to determine whether the heating control information needs to be updated. For example: when the heated time is T1, the current time node determined is P1, and the temperature corresponding to the current time node P1 is TP1; when the heated time determined at the next moment is T2, the current time node determined is P2, and the temperature corresponding to the current time node P2 is TP2. It is determined whether TP2 is the same as TP1. If they are different, it means that the temperature control of the heating needs to be changed. It can be understood that when the heating element starts to be heated, the temperature corresponding to the first time node in the time-temperature variation curve is the initial heating temperature. As the heated time increases, the node temperature corresponding to the current time node may be inconsistent with the initial heating temperature. At this time, it is necessary to determine the node temperature corresponding to the current time node as the target temperature, and generate heating control information according to the target temperature. Through the above steps, the atomization unit can heat the heating element according to the initial heating temperature first. When the heating time reaches the time node at which the node temperature changes on the time-temperature change curve, the control unit uses the node temperature corresponding to the current time node, that is, the target temperature, to regenerate the heating control information and send it to the atomization unit so that the atomization unit can heat the aerosol matrix according to the time-temperature curve.

[0074] As an example, after the control unit outputs that the initial heating temperature reaches a preset time, a preheating completion prompt message may be output to prompt the user that the current aerosol matrix has completed preheating and has released aerosol.

[0075] In some implementations of the embodiments of the present application, before sending the heating control information to the atomization unit, the method further includes: determining a heating temperature in response to detecting a target operation event; and updating the heating control information using the heating temperature.

[0076] The target operation event may be an aerosol inhalation event. When the target event is detected, it indicates that the temperature of the aerosol matrix needs to be increased to release the aerosol faster. Therefore, when the control unit detects the target operation event, it is determined that the heating element needs to be heated up, and the heating temperature is determined and the heating control information is updated using the heating temperature, and the atomization unit is instructed to heat the aerosol according to the heating control information within a certain period of time to perform temperature compensation on the aerosol matrix.

[0077] The embodiment of the present application does not limit the method for determining the heating temperature. As an example, the determination method may be that the control unit reads the heating temperature from the atomization unit, or the control unit determines it based on the current time-temperature curve.

[0078] In some implementations of the embodiments of the present application, before generating heating control information based on the temperature change information, the method also includes: determining the working state of the atomization part according to a first preset frequency; and when the working state is a normal state, generating heating control information based on the temperature change information.

[0079] During the operation of the control unit, the working state of the atomization unit can be continuously determined according to the first preset frequency. When the working state of the atomization unit is normal, heating control information is generated to ensure the safety of users using the heating without burning appliance.

[0080] In some implementations of the embodiments of the present application, the method further includes: generating stop heating information when the working state is an abnormal state, or when a preset end heating event is detected; and sending the stop heating information to the atomization unit to instruct the atomization unit to stop heating the aerosol matrix.

[0081] In some cases, the atomization unit may be in an abnormal working state due to its own factors or environmental factors. At this time, the control unit generates a stop heating message to instruct the atomization unit to stop heating the aerosol matrix to avoid damage to the atomization unit due to excessive temperature caused by continued heating of the aerosol matrix.

[0082] The preset heating end event may be a predetermined event, for example: the control unit receives an end heating operation, the current heating time reaches a preset time threshold, the number of aerosol matrix releases reaches a preset number threshold, etc.

[0083] In some implementations of the embodiments of the present application, the atomization unit includes a substrate and a heating element connected to the substrate. Figure 3 , shows another schematic diagram of a heating without burning device provided in an embodiment of the present application; Figure 3 As shown, the atomization unit includes a heating element, a first control unit communicating with the control unit, and a thermistor connected to the first control unit, a heating circuit and a temperature measuring circuit; the heating element is connected to the heating circuit and the temperature measuring circuit. The heating circuit is used to heat the heating element so that the heating element generates heat and accurately reaches a certain temperature; wherein the temperature measuring circuit is used to measure the resistance information of the heating element, and calculate the temperature of the heating element based on the current resistance information and the resistance temperature coefficient corresponding to the heating element. The resistance of the heating element is related to the temperature, that is, the resistance of the heating element is different under different temperature conditions. Therefore, the resistance temperature coefficient of the heating element can be determined in advance, and when the atomization unit is working, the current temperature of the heating element can be calculated based on the current resistance value of the heating element determined by the temperature measuring circuit and the resistance temperature coefficient, and then the temperature of the heating element can be collected and controlled by PID (Proportional-Integral-Derivative Control).

[0084] Correspondingly, the control unit may be provided with a second control unit, and the second control unit is used to communicate with the above-mentioned first control unit.

[0085] In this implementation, determining the working state of the atomization unit includes:

[0086] Acquiring operating characteristic information of the atomization unit; the operating characteristic information includes: the resistance value of the heating element, and / or the substrate temperature of the substrate;

[0087] When the working characteristic information meets a preset condition, determining that the working state of the atomization unit is a normal state;

[0088] When the working characteristic information does not satisfy a preset condition, it is determined that the working state of the atomization unit is an abnormal state.

[0089] The working characteristic information of the atomization unit may include at least one of the resistance value of the heating element read by the temperature measuring circuit of the atomization unit and the substrate temperature detected by the thermistor. The preset condition may be a resistance range and a board temperature range that match the atomization unit. If the electronic value of the heating element is within the resistance range, it is determined that the resistance value meets the corresponding preset condition; if the substrate temperature is within the board temperature range, it is determined that the substrate temperature meets the preset condition. If and only if the working characteristic information meets the preset conditions, the working state of the atomization unit is determined to be a normal state; if any one or more of the working characteristic information does not meet the corresponding preset conditions, the working state of the atomization unit is determined to be an abnormal state.

[0090] During the process of the atomization unit controlling the heating element to generate heat, the atomization unit can determine the time difference between the time when the target heating control information is received and the current time; if the time difference is greater than a preset first time length, the heating of the aerosol matrix is ​​stopped.

[0091] The atomization unit can determine whether it is still possible to periodically obtain the heating control information issued by the control unit based on the time difference between the most recently received heating control information and the current time, and by comparing the time difference with the preset first time length. The first time length is greater than the time interval for the control unit to issue the heating control information. When the time difference is greater than the first time length, it is determined that the heating control information periodically issued by the control unit cannot be successfully received, and the heating element cannot be incorrectly controlled. At this time, the atomization unit automatically stops the heating element from heating to stop heating the aerosol matrix.

[0092] Reference Figure 4 , showing a schematic diagram of an example of a heating process of a heating-without-combustion device provided in an embodiment of the present application, comprising the following steps:

[0093] Step 401: The control unit receives a heating start operation.

[0094] Step 402: The control unit reads temperature change information and operating characteristic information from the atomization unit.

[0095] Step 403: The control unit determines that the atomization unit is in a normal working state and then starts heating.

[0096] Step 404, sending a heating start command and an initial heating temperature to the atomization unit.

[0097] Step 405: The atomization unit starts PID to collect and control the temperature of the heating element in real time.

[0098] Step 406: The control unit continues to send a heating command, and when there is a temperature change at a time node of the temperature curve, sends a new target temperature to be controlled to the atomization unit.

[0099] Step 407: The atomization unit receives the new target temperature and updates the PID target temperature.

[0100] Step 408: The control unit reads the board temperature and connection status in real time.

[0101] In step 409, the control unit continuously determines that the connection with the atomization unit is normal and the substrate temperature is normal. The control unit may continuously execute step 409 during the heating process. If the connection with the atomization unit is abnormal or the substrate temperature is abnormal, steps 410-411 are executed. If the connection with the atomization unit is normal and the substrate temperature is normal, step 406 is executed.

[0102] In step 410, the control unit sends a command to the atomization unit to end heating.

[0103] Step 411, the atomization unit stops controlling the heating element to generate heat.

[0104] During the heating process of the heating element, steps 412, 413, and 414 may be triggered at any time.

[0105] Step 412: The control unit detects the target operation event and sends a heating temperature to the atomization unit.

[0106] Step 413: The control unit detects a preset heating end event.

[0107] Step 414: the atomization unit does not receive a command for a certain period of time.

[0108] In some implementations of the embodiments of the present application, since the atomization unit is provided with a heating element, and the temperature control of the heating element requires the determination of an accurate initial resistance value (the resistance value of the heating element before the temperature rises) and a resistance temperature coefficient, the initial resistance value and the resistance temperature coefficient of the heating element in each atomization unit are not necessarily the same, so the atomization unit needs to be calibrated before being controlled by the control unit to heat the heating element for the first time to determine the above-mentioned initial resistance value and resistance temperature coefficient. The method also includes: determining the initial temperature of the heating element and receiving the initial resistance value sent by the atomization unit; sending a calibration command to the atomization unit to instruct the atomization unit to control the heating element to be heated to a calibration temperature; when detecting that the actual temperature of the heating element is consistent with the calibration temperature, receiving the calibration resistance value sent by the atomization unit; generating a resistance temperature coefficient matching the atomization unit based on the initial temperature, the initial resistance value, the calibration temperature, and the calibration resistance value; controlling the atomization unit to store calibration information; the calibration information includes the initial temperature, the initial resistance value, and the resistance temperature coefficient.

[0109] The control unit can use its own temperature sensing element (including but not limited to infrared sensors) to control the actual temperature before the atomization unit heats the heating element as the initial temperature, and receive the current resistance value of the heating element sent by the atomization unit as the initial resistance value. The control unit sends a calibration command including the calibration temperature to the atomization unit. In response to the calibration command, the atomization unit starts to heat the heating element so that the heating element gradually heats up to the calibration temperature.

[0110] During the heating process of the heating element, the control unit determines the real-time actual temperature of the heating element through the above-mentioned temperature sensing element. When the real-time actual temperature is the calibration temperature, the resistance value of the heating element currently detected by the atomization unit is determined to be the calibration resistance value. According to the initial resistance value, initial temperature, calibration resistance value and calibration temperature, the resistance temperature coefficient matching the heating element is calculated, and the atomization unit is controlled to store the initial temperature, initial resistance value and resistance temperature coefficient.

[0111] Reference Figure 5 , a schematic diagram showing an example of a calibration process of a heating-not-burning appliance provided in an embodiment of the present application is shown, comprising the following steps:

[0112] Step 501: The control unit receives a calibration start operation.

[0113] Step 502: The control unit reads the current resistance value of the atomization unit heating element and records it as the initial resistance value.

[0114] Step 503: The control unit sends a command to the atomization unit to heat the atomization unit at a calibrated temperature.

[0115] Step 504: the atomizing unit controls the heating element to generate heat using a default resistance temperature coefficient.

[0116] Step 505: The control unit detects the actual temperature of the heating element.

[0117] Step 506: The control unit calculates a new resistance temperature coefficient and sends it to the atomization unit.

[0118] Step 507: the atomizing unit controls the heating element to generate heat using the new resistance temperature coefficient.

[0119] In step 508, the control unit determines whether the actual temperature is consistent with the calibration temperature. If not, the control unit returns to step 505. If yes, the control unit executes steps 509-510.

[0120] Step 509: the control unit sends a heating end command to the atomization unit to instruct the atomization unit to stop controlling the heating element to generate heat.

[0121] In step 510, the control unit sends a hold command to instruct the atomization unit to save the initial resistance value and the current resistance temperature coefficient.

[0122] Reference Figure 6, shows a schematic diagram of another heating control method provided by an embodiment of the present application, which is applied to an atomizing part in a heat-not-burn device, wherein the atomizing part and the control part transmit signals via wired or wireless means; the atomizing part is used to contain an aerosol matrix; and specifically may include the following steps:

[0123] Step 601, receiving heating control information;
