[0064] Heat Not Burning (HNB) devices are devices that use the thermal effect of a heating element to heat an aerosol-generating substrate so that the aerosol-generating substrate generates aerosol without burning.

[0065] Currently, the control board of an HNB device includes a battery cell, display screen, and heating element. During the HNB device production process, after the control board is assembled into the HNB device, the battery cell, display screen, and heating element are uniformly tested for performance.

[0066] Although battery cells, displays, and heating elements undergo factory inspection by suppliers, some of these elements inevitably experience defects during assembly. However, if these defects are detected in a finished HNB device, the control board of the device will need to be reworked, increasing the rework rate for HNB devices.

[0067] In response to the above-mentioned problems, the embodiments of the present application provide a self-inspection method for a control board, a heating-without-combustion device, and a storage medium. In response to an acquired self-inspection instruction, the method determines whether the battery cells of the control board have passed the inspection. The self-inspection instruction is used to indicate that the control board has been packaged and is to be assembled into a heating-without-combustion device. When it is determined that the battery cells have passed the inspection, the method determines whether the display screen of the control board has passed the inspection. When it is determined that the display screen has passed the inspection, the method determines whether the heating element of the control board has passed the inspection. When it is determined that the heating element has passed the inspection, the method determines that the control board has passed the inspection. This achieves the goal of determining that the control board has passed the self-inspection when the battery cells, display screen, and heating element of the control board are inspected in sequence when the control board has been packaged. In the production process of the HNB device, the number of unqualified control boards assembled into the HNB device can be reduced. This can prevent the problem of needing to rework the control board of the abnormal HNB device when an abnormality is detected after the control board is assembled into the finished HNB device. This is beneficial to reducing the production rework rate of the HNB device.

[0068] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0069] See also Figure 1 , which shows a schematic diagram of an application scenario of the HNB device 100 provided in an embodiment of the present application. The HNB device 100 may include a housing 101, a battery cell 102, a display screen 103, a heating element 104, and a controller 105. The battery cell 102, the display screen 103, the heating element 104, and the controller 105 may be installed in the housing 101, and the housing 101 may provide installation support for the battery cell 102, the display screen 103, the heating element 104, and the controller 105.

[0070] The housing 101 may be provided with a medium cavity for storing an aerosol-generating matrix. The aerosol-generating matrix is used to generate an aerosol after heating. The main components of the aerosol-generating matrix may include glycerin, propylene glycol, flavoring, and nicotine, etc., which are not limited here.

[0071] The material of the shell 101 can be any one of engineering plastics (for example, polycarbonate (PC), polystyrene (PS), nylon (PA), polyimide (PI), etc.), aluminum alloy, stainless steel or ABS plastic (Acrylonitrile Butadiene Styrene Plastic, ABS plastic), etc., and is not limited here.

[0072] The battery cell 102 can be electrically connected to the display screen 103 , the heating element 104 and the controller 105 and provide power to the display screen 103 , the heating element 104 and the controller 105 . The battery cell 102 can be packaged into a control board together with the display screen 103 , the heating element 104 and the controller 105 .

[0073] The display screen 103 may be any one of a light-emitting diode (LED) display screen, an organic light-emitting diode (OLED) display screen, or a liquid crystal display (LCD) display screen, etc., which is not limited here.

[0074] The heating element 104 can be used to heat the aerosol-generating substrate stored in the medium cavity to generate aerosol. The heating element 104 can be any one of a resistance heating element, an electromagnetic heating element, or an infrared heating element, which is not limited here.

[0075] The controller 105 can be communicatively connected to the battery cell 102 , the display screen 103 and the heating element 104 . The controller 105 can be used to control the battery cell 102 , the display screen 103 and the heating element 104 to operate.

[0076] The controller 105 can be any one of a microcontroller unit (MCU), a central processing unit (CPU), a combinatorial logic controller (CLC), a complex programmable logic device (CPLD) or a field programmable gate array (FPGA), etc., and is not limited here.

[0077] See also Figure 2 , which shows a flow chart of a self-test method of a control panel provided by an embodiment of the present application. In a specific embodiment, the self-test method of the control panel can be applied to Figure 1 The controller 105 in the HNB device 100 shown in FIG. 1 is used as an example below. Figure 2 The process shown in FIG. 1 is described in detail. The self-test method of the control board may include the following steps 201 to 204.

[0078] Step 201: In response to the acquired self-test instruction, determine whether the battery cells of the control board pass the test.

[0079] In an embodiment of the present application, the controller can obtain a self-test instruction, and in response to the obtained self-test instruction, test the battery cells of the control board and determine whether the battery cells pass the test.

[0080] The self-test instruction may be used to indicate that the control board has been packaged and is ready to be assembled into an HNB device.

[0081] Specifically, the HNB device may further include an ADC sampling circuit, which is electrically connected to the battery cell and the controller. The ADC sampling circuit may be used to collect the battery cell voltage of the battery cell.

[0082] The controller can obtain a self-test instruction, and in response to the obtained self-test instruction, send a first acquisition instruction to the ADC sampling circuit. The ADC sampling circuit receives and responds to the first acquisition instruction, collects the cell voltage of the battery cell, and sends the collected cell voltage to the controller. The controller receives the cell voltage returned by the ADC sampling circuit, and determines whether the battery cell passes the test based on the cell voltage. The judgment of whether the battery cell passes the test is based on the detected cell voltage, thereby improving the accuracy of judging whether the battery cell passes the test.

[0083] When the cell voltage is within the preset voltage range, it is determined that the cell has passed the test; when the cell voltage is outside the preset voltage range, it is determined that the cell has failed the test.

[0084] The preset voltage range may be used to represent the voltage range of the battery cell when the HNB device is working normally. The preset voltage range may be a voltage range preset by the user.

[0085] As an example, the preset voltage range may be [3.9 volts (V), 4.2 V], which is not limited here.

[0086] Step 202: When it is determined that the battery cell has passed the test, determine whether the display screen of the control panel has passed the test.

[0087] In an embodiment of the present application, when the controller determines that the battery cell has passed the test, the display screen of the control board can be tested to determine whether the display screen has passed the test.

[0088] Specifically, when the controller determines that the battery cell has passed the test, it can send a display instruction to the display screen. The display screen receives and responds to the display instruction, and the display screen displays. The controller generates a first confirmation prompt message, and receives the first confirmation information input by the user based on the first confirmation prompt message, and determines whether the display screen has passed the test based on the first confirmation information. Whether the display screen has passed the test is judged based on the first confirmation information, thereby improving the accuracy of judging whether the display screen has passed the test.

[0089] Among them, the display instruction can be used to instruct the display screen to display, the first confirmation prompt information can be used to prompt the user to input the first confirmation information to the controller, and the first confirmation information can include a first confirmation result used to characterize that the display screen displays normally, and a second confirmation result used to characterize that the display screen displays abnormally.

[0090] When the first confirmation result is received, it is determined that the display screen has passed the test; when the second confirmation result is received, it is determined that the display screen has failed the test.

[0091] As an example, when the display screen displays normally, the lights of various colors on the display screen or the display screen display normally display for 0.3 seconds, which is not limited here.

[0092] Step 203: When it is determined that the display screen has passed the test, determine whether the heating element of the control panel has passed the test.

[0093] In an embodiment of the present application, when the controller determines that the display screen has passed the test, the heating element of the control panel may be tested to determine whether the heating element has passed the test.

[0094] Specifically, the HNB device may further include a resistance sensor, which is electrically connected to the controller and can be used to collect the resistance value of the heating element.

[0095] When the controller determines that the display screen has passed the test, it can send a second acquisition instruction to the resistance sensor. The resistance sensor receives and responds to the second acquisition instruction, collects the resistance of the heating element, obtains the resistance of the heating element, and sends the resistance of the heating element to the controller. The controller receives the resistance of the heating element returned by the resistance sensor, and determines whether the heating element has passed the test based on the resistance of the heating element. The judgment of whether the heating element has passed the test is based on the detected resistance of the heating element, thereby improving the accuracy of judging whether the heating element has passed the test.

[0096] When the resistance of the heating element is within the preset resistance range, it is determined that the heating element has passed the test; when the resistance of the heating element is outside the preset resistance range, it is determined that the heating element has failed the test.

[0097] The preset resistance range may be used to represent the resistance range of the heating element when the HNB device is working normally. The preset resistance range may be a resistance range preset by a user.

[0098] As an example, the preset resistance range may be [0.5 ohm (Ω), 1.5 Ω], which is not limited here.

[0099] The resistance sensor may be any one of a thermal resistance sensor, a strain gauge resistance sensor, a piezoresistive resistance sensor, a gas resistance sensor, etc., and is not limited here.

[0100] Step 204: When it is determined that the heating element has passed the test, it is determined that the control board has passed the test.

[0101] In an embodiment of the present application, when the controller determines that the heating element has passed the inspection, it can be determined that the control board has passed the inspection, so that when it is determined that the control board has completed packaging, the control board self-inspection is determined to be qualified by sequentially inspecting the battery cells, display screen and heating element of the control board. In the production process of the HNB device, it can reduce the number of unqualified control boards assembled into HNB devices, and can prevent the problem of needing to rework the control board of the abnormal HNB device finished product when an abnormality of the control board is detected after the control board is assembled into the HNB device finished product, which is beneficial to reducing the production rework rate of the HNB device.

[0102] In some embodiments, when the controller determines that the battery cell has failed the test, it can generate a first processing prompt message, and when it receives the first confirmation processing message, it returns to the step of determining whether the battery cell of the control board has passed the test until step 204, thereby achieving continuous testing of the battery cell, which is beneficial to improving the production yield of the HNB device.

[0103] The first processing prompt information can be used to prompt the user to process the battery cell and input the first processing confirmation information to the controller. The first processing confirmation information can be used to indicate that the user has processed the battery cell.

[0104] As an example, the preset voltage range can be [3.9V, 4.2V], and the first processing prompt information can include charging prompt information and discharging prompt information. The charging prompt information can be used to prompt the user to charge the battery cell until the battery cell voltage is [3.9V, 4.2V], and the discharging prompt information can be used to prompt the user to discharge the battery cell until the battery cell voltage is [3.9V, 4.2V].

[0105] When the cell voltage is less than 3.9V, it is determined that the cell has failed the test, and a charging prompt message can be generated; when the cell voltage is greater than 4.2V, it is determined that the cell has failed the test, and a discharging prompt message can be generated.

[0106] In some embodiments, when the controller determines that the display screen has failed the inspection, it may generate a second processing prompt message, and upon receiving the second confirmation processing message, return to the step of determining whether the display screen has passed the inspection, until step 204, thereby achieving continuous inspection of the display screen, which is beneficial to improving the production yield of the HNB device.

[0107] The second processing prompt information can be used to prompt the user to replace the display screen and input the second confirmation processing information to the controller. The second confirmation processing information can be used to indicate that the user has replaced the display screen.

[0108] In some embodiments, when the controller determines that the heating element has not passed the test, a third processing prompt message may be generated, and when the third confirmation processing message is received, the controller returns to the step of determining whether the heating element has passed the test until step 204, thereby achieving continuous detection of the heating element, which is beneficial to improving the production yield of the HNB device.

[0109] The third processing prompt information can be used to prompt the user to replace the heating element and input the third confirmation processing information to the controller. The third confirmation processing information can be used to indicate that the user has replaced the heating element.

[0110] The solution provided by the present application determines whether the battery cells of the control board have passed the test in response to the obtained self-test instructions. The self-test instructions are used to indicate that the control board has been packaged. When it is determined that the battery cells have passed the test, it is determined whether the display screen of the control board has passed the test. When it is determined that the display screen has passed the test, it is determined whether the heating element of the control board has passed the test. When it is determined that the heating element has passed the test, it is determined that the control board has passed the test. This achieves that when it is determined that the control board has been packaged, the control board is determined to have passed the self-test by sequentially testing the battery cells, display screen, and heating element of the control board. In the production process of HNB devices, the number of unqualified control boards assembled into HNB devices can be reduced, and the problem of needing to rework the control board of the abnormal HNB device finished product when an abnormality is detected in the control board after the control board is assembled into the HNB device can be suppressed. This is conducive to reducing the production rework rate of HNB devices.

[0111] See also Figure 3 , which shows a flow chart of a self-test method of a control panel provided by another embodiment of the present application. In a specific embodiment, the self-test method of the control panel can be applied to Figure 1 The controller 105 in the HNB device 100 shown in FIG. 1 is used as an example below. Figure 3 The process shown in FIG. 1 is described in detail. The self-test method of the control board may include the following steps 301 to 305.

[0112] Step 301: In response to the acquired self-test instruction, determine whether the battery cells of the control board pass the test.

[0113] Step 302: When it is determined that the battery cell has passed the test, determine whether the display screen of the control panel has passed the test.

[0114] In this embodiment, step 301 and step 302 may refer to the contents of the corresponding steps in the aforementioned embodiment, and will not be repeated here.

[0115] Step 303: When it is determined that the display screen passes the test, determine whether the motor of the control board passes the test.

[0116] In this embodiment, the HNB device may further include a motor. The motor may be electrically connected to the battery cell and the controller. The motor may be packaged into a control board together with the battery cell, the display screen, the heating element, and the controller.

[0117] When the controller determines that the display screen passes the test, the controller may test the motor of the control board to determine whether the motor passes the test.

[0118] Specifically, when the controller determines that the display screen has passed the test, it can send a vibration command to the motor. The motor receives and responds to the vibration command, and the motor vibrates. The controller generates a second confirmation prompt message, and receives the second confirmation information entered by the user based on the second confirmation prompt message, and determines whether the motor has passed the test based on the second confirmation information. Judging whether the motor has passed the test based on the second confirmation information improves the accuracy of judging whether the motor has passed the test.

[0119] Among them, the vibration instruction can be used to instruct the motor to vibrate, and the second confirmation prompt information can be used to prompt the user to input second confirmation information to the controller. The second confirmation information may include a third confirmation result used to characterize that the vibration duration of the motor is greater than or equal to the duration threshold, and a fourth confirmation result used to characterize that the vibration duration of the motor is less than the duration threshold.

[0120] When the third confirmation result is received, it is determined that the motor has passed the test; when the fourth confirmation result is received, it is determined that the motor has failed the test.

[0121] The duration threshold may be used to represent the minimum vibration duration of the motor when the HNB device is working normally. The duration threshold may be a vibration duration preset by the user.

[0122] As an example, the duration threshold may be 0.3s, which is not limited here.

[0123] Step 304: When it is determined that the motor has passed the test, determine whether the heating element has passed the test.

[0124] In this embodiment, when the controller determines that the motor has passed the test, it can determine whether the heating element has passed the test, so that when it is determined that the control board has been packaged, the control board self-inspection is determined to be qualified by sequentially testing the battery cell, display screen, motor and heating element of the control board. In the production process of the HNB device, it can reduce the number of unqualified control boards assembled into HNB devices, and can prevent the problem of needing to rework the control board of the abnormal HNB device finished product when an abnormality of the control board is detected after the control board is assembled into the HNB device finished product, which is beneficial to reducing the production rework rate of the HNB device.

[0125] Step 305: When it is determined that the heating element has passed the test, it is determined that the control board has passed the test.

[0126] In this embodiment, step 305 can refer to the contents of the corresponding steps in the above embodiments, which will not be repeated here.

This achieves the goal of determining that the control board has passed the self-test when the battery cells, display screen, and heating element of the control board are tested in sequence when the control board has been packaged. In the production process of HNB devices, the number of unqualified control boards assembled into HNB devices can be reduced, and the problem of needing to rework the control board of the abnormal HNB device finished product when an abnormality is detected in the control board after the control board is assembled into the finished HNB device can be suppressed. This is conducive to reducing the production rework rate of HNB devices.
