[0042] Please see Figure 1 This application provides an embodiment of an aerosol generating device 100, comprising: a battery cell 11 for providing power; a device interface device 12, wherein a first branch 101 is established between the positive terminal of the battery cell 11 and the device interface device 12, and a second branch 102 is established between the device interface device 12 and the ground terminal GND of the aerosol generating device 100, the first branch 101 and the second branch 102 being separate from each other; and an impedance circuit 13 disposed in the first branch 101, the impedance circuit 13 being configured such that when a voltage detection device is connected to the device interface device 12, the first branch 101, the voltage detection device and the second branch 102 form a loop, thereby enabling the battery cell voltage to be detected externally to the aerosol generating device 100, the battery cell voltage being used to determine whether the self-discharge of the aerosol generating device 100 meets a preset standard. The negative terminal of the battery cell 11 is electrically connected to the ground terminal GND of the aerosol generating device 100.

[0043] The battery cell 11 provides power for operating the aerosol generating apparatus 100. For example, the battery cell 11 can provide power to heat the heating element of the aerosol generating apparatus 100, and can provide power required for operating circuits (e.g., drive circuits). In addition, the battery cell 11 can provide power required to operate sensors (e.g., airflow sensors, temperature sensors, etc.), motors, etc. provided in the aerosol generating apparatus 100.

[0044] The battery cell 11 can be, but is not limited to, a lithium iron phosphate (LiFePO4) battery cell, a lithium cobalt oxide (LiCoO2) battery cell, or a lithium titanate battery cell. The battery cell 11 can be a rechargeable battery cell or a disposable battery cell. When the battery cell 11 is a rechargeable battery cell, the aerosol generating device 100 also includes a charging circuit electrically connected to the battery cell 11 for charging the battery cell 11. In addition, the battery cell 11 also includes a PCM (Protection Circuit Module), electrically connected to the charging circuit. The PCM is the core component in the battery cell 11 that implements basic safety protection, used to prevent overcharging, over-discharging, short circuits, and overcurrent of the battery cell 11.

[0045] In some embodiments, the device interface device 12 includes a first ground pin 121, a second ground pin 122, and a conductive housing 123.

[0046] The device interface 12 can be a USB TPYEC interface. Common USB TPYEC interfaces include 6-pin TPYEC, 12-pin TPYEC, 16-pin TPYEC, and 24-pin TPYEC interfaces. The 6-pin TPYEC interface is a simplified version that retains only the charging function, eliminating all data transmission pins. It features high-current fast charging and reverse insertion protection, and can be used in scenarios where only charging is required, such as the aerosol generation device 100. Depending on the requirements of the scenario, a USB TPYEC interface with a different number of pins can be selected. For example, when the aerosol generation device 100 is required to support PD fast charging, a 12-pin TPYEC interface with at least one set of data transmission pins should be selected.

[0047] In this embodiment, the device interface device 12 is a TPYEC female connector. The TPYEC female connector and the TPYEC male connector are physically connected, but internally they are not connected. It is understood that the device interface device 12 can also be other interface devices with multiple connector combinations that are not internally connected. The first ground pin 121 and the second ground pin 122 are a set of GND pins (i.e., GND1 pin and GND2 pin) of the TPYEC female connector. Taking a 6-pin TPYEC female connector as an example, the device interface device 12 also includes a set of VBUS pins (i.e., VBUS1 pin and VBUS2 pin) and a set of CC pins (i.e., CC1 pin and CC2 pin).

[0048] In some embodiments, the device interface device 12 may also be a POGO PIN, a button, or other interface device with external electrical capabilities.

[0049] One or two of the first grounding pin 121, the second grounding pin 122, and the conductive housing 123 are disposed in the first branch 101, and the remaining two or one of the first grounding pin 121, the second grounding pin 122, and the conductive housing 123 are disposed in the second branch 102. This includes at least the following cases:

[0050] The first grounding pin 121 is provided in the first branch 101, and the second grounding pin 122 is provided in the second branch 102;

[0051] The first grounding pin 121 is disposed in the first branch 101, and the conductive housing 123 is disposed in the second branch 102;

[0052] The first grounding pin 121 is disposed in the first branch 101, and the second grounding pin 122 and the conductive housing 123 are disposed in the second branch 102;

[0053] The first grounding pin 121 and the second grounding pin 122 are disposed in the first branch 101, and the conductive housing 123 is disposed in the second branch 102;

[0054] The first grounding pin 121 and the conductive housing 123 are disposed in the first branch 101, and the second grounding pin 122 is disposed in the second branch 102;

[0055] The second grounding pin 122 is provided in the first branch 101, and the first grounding pin 121 is provided in the second branch 102;

[0056] The second grounding pin 122 is disposed in the first branch 101, and the conductive housing 123 is disposed in the second branch 102;

[0057] The second grounding pin 122 is disposed in the first branch 101, and the first grounding pin 121 and the conductive housing 123 are disposed in the second branch 102;

[0058] The second grounding pin 122 and the conductive housing 123 are disposed in the first branch 101, and the first grounding pin 121 is disposed in the second branch 102;

[0059] The conductive outer casing 123 is disposed in the first branch 101, and the first grounding pin 121 is disposed in the second branch 102;

[0060] The conductive housing 123 is disposed in the first branch 101, and the second grounding pin 122 is disposed in the second branch 102;

[0061] according to Figure 2 In the embodiment shown, the first grounding pin 121 is disposed in the first branch 101, and the impedance circuit 13 is electrically connected between the positive terminal of the battery cell 11 and the first grounding pin 121; the second grounding pin 122 is disposed in the second branch 102; the conductive outer shell 123 is either suspended or electrically connected to the first grounding pin 121 or electrically connected to the second grounding pin 122.

[0062] Under normal circumstances, the first grounding pin 121 is in a floating state. The first grounding pin 121 is connected to the positive terminal of the cell 11 through the impedance circuit 13. At this time, the impedance circuit 13 does not consume current.

[0063] The equivalent resistance of impedance circuit 13 ranges from 100Ω to 100MΩ.

[0064] In some alternative embodiments, the impedance circuit 13 includes at least one resistor.

[0065] As one example, such as Figure 3a As shown, impedance circuit 13 includes resistor R1. As one example, such as... Figure 3bAs shown, the impedance circuit 13 includes resistors R1 to Rn connected in series, where n is an integer greater than or equal to 2.

[0066] In some alternative embodiments, the impedance circuit 13 includes a unidirectional conducting element and at least one resistor connected in sequence.

[0067] By utilizing the unidirectional nature of the unidirectional conducting element, the return of large external current to the positive terminal of cell 11 is prevented, thereby improving the safety of cell 11.

[0068] In one embodiment, the unidirectional conducting element includes a diode, the anode of which is electrically connected to the positive terminal of the cell 11, and the cathode of which is electrically connected to a first ground pin 121 through at least one resistor.

[0069] As one example, such as Figure 3c As shown, the impedance circuit 13 includes a diode D1 and a resistor R1; the anode of diode D1 is electrically connected to the positive terminal of the battery cell 11, and the cathode of diode D1 is electrically connected to the first ground pin 121 through resistor R1. As one example, ... Figure 3d As shown, the impedance circuit 13 includes a diode D1 and resistors R1 to Rn connected in series, where n is an integer greater than or equal to 2; the anode of diode D1 is electrically connected to the positive terminal of cell 11, and the cathode of diode D1 is electrically connected to the first ground pin 121 through resistors R1 to Rn connected in series.

[0070] In some alternative embodiments, the aerosol generating device 100 further includes a device controller 40 electrically connected to the battery cell 11; the impedance circuit 13 includes at least one switching transistor, the first end of which is electrically connected to the positive terminal of the battery cell 11, the second end of which is electrically connected to the first ground pin 121, and the third end of which is electrically connected to the device controller 40, the device controller 40 being configured to control the switching transistor to turn on.

[0071] The switching transistor can be a field-effect transistor, thyristor, triac, transistor, IGBT, or other switching devices. When the switching transistor is turned on, it contains components such as diodes, and its equivalent resistance ranges from 100Ω to 100MΩ. Since the first ground pin 121 is in a floating state, the voltage of the first ground pin 121 is pulled up by the switching transistor to be equal to the cell voltage.

[0072] In some other embodiments, when preset conditions are met, the device controller 40 is configured to control the switch tube to turn off, thereby cutting off the first branch 101 and improving the safety of the aerosol generating device 100.

[0073] The following are some examples of methods for determining whether the self-discharge of the aerosol generating device 100 meets the preset standard using cell voltage:

[0074] Example 1: Determine the reference voltage Vref based on the quiescent current of the PCBA system and the maximum self-discharge of cell 11; detect the cell voltage V1 on day 1... detect the cell voltage VN on day N; calculate whether the ratio (VN-V1) / (N-1) is less than or equal to Vref. If so, determine that the self-discharge of the aerosol generating device 100 meets the preset standard. The quiescent current of the PCBA system can be obtained from the cell voltage and the SOC curve of cell 11. The maximum self-discharge of cell 11 is known; the self-discharge of a standard cell 11 is ≤3mV.

[0075] Example 2: For aerosol generating devices 100 in the same batch, at the first moment, the cell voltage V1 of each aerosol generating device 100 is detected, and at the second moment, the cell voltage V2 of each aerosol generating device 100 is detected; the voltage difference V0 of each aerosol generating device 100 is calculated as (V2-V1); the voltage difference V0 with significant difference is selected, and it is determined that the self-consumption of the corresponding aerosol generating device 100 does not meet the preset standard.

[0076] Example 3: Construct a standard aerosol generating device 100; detect the daily cell voltage of the standard aerosol generating device 100 over a period of time; detect the daily cell voltage of the aerosol generating device 100 to be tested over a period of time; compare the daily cell voltage of the aerosol generating device 100 to be tested over a period of time with the daily cell voltage of the standard aerosol generating device 100 over a period of time to see if the difference is within a reasonable range. If so, determine that the self-consumption of the aerosol generating device 100 meets the preset standard.

[0077] It should be noted that the decrease in cell voltage can reflect the change in the self-consumption of the aerosol generating device 100. Therefore, the method for determining whether the self-consumption of the aerosol generating device 100 meets the preset standard based on the cell voltage is not limited to the above method. It can be reasonably designed according to the specific requirements in the product research and development and production process.

[0078] The aerosol generating device provided in this application establishes a first branch between the positive terminal of the battery cell and the device interface device, and a second branch between the device interface device and the ground terminal of the aerosol generating device. The first and second branches are separate from each other. An impedance circuit is set in the first branch. The impedance circuit is configured such that when the voltage detection device is connected to the device interface device, the first branch, the voltage detection device, and the second branch form a loop, thereby enabling the battery cell voltage to be detected externally to the aerosol generating device. The battery cell voltage is used to determine whether the self-discharge of the aerosol generating device meets a preset standard. Therefore, it is possible to determine whether the self-discharge of the aerosol generating device meets a preset standard without disassembling the device, thus enabling a low-cost aerosol generating device to meet the preset standard.

[0079] Please see Figure 4 This application provides an embodiment of an aerosol generation system 300, including: an aerosol generation device 100 as described in any of the above embodiments; a voltage detection device 200, which is electrically connected to a device interface device 12, the voltage detection device 200 being configured to detect the cell voltage when the voltage detection device 200 is electrically connected to the device interface device 12, the cell voltage being used to determine whether the self-consumption of the aerosol generation device meets a preset standard.

[0082] Adaptively, the detection interface device 21 is a TPYEC connector. In some embodiments, the detection interface device 21 may be omitted.

[0083] Voltage detection circuit 22, the two ends of voltage detection circuit 22 are electrically connected to the first connection pin 211 and the second connection pin 212 respectively, and voltage detection circuit 22 is configured to detect cell voltage when detection interface device 21 and device interface device 12 are electrically connected.

[0084] like Figure 5 As shown, when the detection interface device 21 and the device interface device 12 are electrically connected, the first connection pin 211 is electrically connected to the first branch 101 through the device interface device 12, and the second connection pin 212 is electrically connected to the second branch 102 through the device interface device 12. Therefore, the voltage across the voltage detection circuit 22 is equal to the voltage difference between the cell 11 and the ground terminal GND, which is equal to the cell voltage. The cell voltage of the cell 11 can be detected without damaging the structure of the aerosol generating device 100.

[0085] In one embodiment, the voltage detection circuit 22 includes a voltmeter.

[0086] In some specific embodiments, the voltmeter displays to three decimal places, enabling more accurate detection of the cell voltage. In other embodiments, the voltage detection circuit 22 can also be a multimeter, oscilloscope, or other measuring instrument capable of measuring DC voltage.

[0087] In some embodiments, the detection interface device 21 and the voltage detection circuit 22 are encapsulated in a fixture.

[0088] By using a fixture to test the cell voltage of the aerosol generating device 100, the connection operation can be simplified and the testing efficiency improved.

[0089] In some embodiments, please continue reading Figure 5 The voltage detection device 200 also includes a detection controller 23 connected to the voltage detection circuit 22. The detection controller 23 is configured to receive the cell voltage output by the voltage detection circuit 22 and determine whether the self-consumption of the aerosol generating device 100 meets the preset standard based on at least one cell voltage.

[0090] In one embodiment, the detection controller 23 pre-stores a program for determining whether the self-consumption of the aerosol generating device 100 meets a preset standard. The program is run, and the self-consumption of the aerosol generating device 100 is determined based on the voltage of at least one battery cell. The method for determining whether the self-consumption of the aerosol generating device 100 meets the preset standard based on the voltage of at least one battery cell can be found in the foregoing description and will not be repeated here.

[0091] In addition, the voltage detection device 200 also includes a display screen for displaying the determination result of whether the self-power consumption of the aerosol generating device 100 meets the preset standard. Alternatively, the voltage detection device 200 also includes a voice module for broadcasting the determination result of whether the self-power consumption of the aerosol generating device 100 meets the preset standard. Alternatively, the voltage detection device 200 also includes LEDs for controlling the LEDs to display information based on the determination result of whether the self-power consumption of the aerosol generating device 100 meets the preset standard, such as displaying color, flashing frequency, flashing pattern, etc. Alternatively, the voltage detection device 200 also includes a wireless communication module for sending the determination result of whether the self-power consumption of the aerosol generating device 100 meets the preset standard to a user terminal.

Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
