The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0049] Please see Figure 1This application provides an embodiment of an aerosol generating device, which includes a plurality of sensing electrodes 10, a plurality of display units 20 and a touch controller 30.

[0050] An inductive capacitor is formed between the inductive electrode 10 and the power supply ground terminal.

[0051] In one embodiment, the sensing electrode 10 includes a copper foil electrically connected to the corresponding detection pin 301.

[0052] Copper foil can be deposited on printed circuit boards. The copper foil primarily senses human touch based on the principle of capacitive sensing. Specifically, when a person is not touching or near the copper foil, the capacitance between the copper foil and the ground is small; when a person touches or nears the copper foil, the capacitance between the copper foil and the ground is large.

[0053] In one embodiment, see Figure 4 and Figure 6 The aerosol generating device includes nine sensing electrodes 10, namely copper foil G1, copper foil G2, copper foil G3, copper foil G4, copper foil G5, copper foil G6, copper foil G7, copper foil G8 and copper foil G9. Specifically, copper foil G1 is electrically connected to the detection pin SEG0 of the touch controller 30 via pin TK0; copper foil G2 is electrically connected to the detection pin SEG1 of the touch controller 30 via pin TK1; copper foil G3 is electrically connected to the detection pin SEG2 of the touch controller 30 via pin TK2; copper foil G4 is electrically connected to the detection pin SEG3 of the touch controller 30 via pin TK3; copper foil G5 is electrically connected to the detection pin SEG4 of the touch controller 30 via pin TK4; copper foil G6 is electrically connected to the detection pin SEG5 of the touch controller 30 via pin TK5; copper foil G7 is electrically connected to the detection pin SEG6 of the touch controller 30 via pin TK6; copper foil G8 is electrically connected to the detection pin SEG7 of the touch controller 30 via pin TK7; and copper foil G9 is electrically connected to the detection pin SEG8 of the touch controller 30 via pin TK8.

[0054] For example, copper foils G1, G2, G3, G4, G5, G6, G7, G8, and G9 are circles of the same size. The nine circular copper foils are arranged in a matrix of three rows and three columns, with equal spacing between adjacent rows or columns, forming a 3x3 grid "chessboard" corresponding to the sensing electrode 10.

[0055] The display unit 20 corresponds one-to-one with the sensing electrode 10, and each display unit 20 is configured to display two different preset patterns.

[0056] Please see Figure 2The display unit 20 includes a first sub-display unit 21 and a second sub-display unit 22. The first sub-display unit 21 includes a plurality of first LEDs 210 connected in parallel, and is configured to display a first preset pattern. The second sub-display unit 22 includes a plurality of second LEDs 220 connected in parallel, and is configured to display a second preset pattern, which is different from the first preset pattern.

[0057] Correspondingly, the display unit 20 is configured as a 3x3 grid "chessboard," with the first sub-display unit 21 and the second sub-display unit 22 representing a "chess piece" for each player. Lighting up either the first sub-display unit 21 or the second sub-display unit 22 indicates that a "chess piece" has been placed at the corresponding position on the 3x3 grid "chessboard." A first preset pattern is formed by arranging multiple parallel first LEDs 210, and a second preset pattern is formed by arranging multiple parallel second LEDs 220. For example, the first preset pattern is "○," and the second preset pattern is "×."

[0058] It is understood that the number of first LEDs 210 in the first sub-display unit 21 can be determined based on the first preset pattern and the hardware parameters of the touch controller 30, etc. The number of second LEDs 220 in the second sub-display unit 22 can be determined based on the second preset pattern and the hardware parameters of the touch controller 30, etc.

[0059] In one embodiment, the first LED 210 and the second LED 220 are different colors. By setting the first LED 210 and the second LED 220 to have different colors, the two sides in the battle can be better distinguished.

[0060] In some embodiments, the display unit 20 can also be used as a UI display for the aerosol generating device. For example, when the user is inhaling, the display unit 20 can be controlled to display the remaining power, remaining oil, etc. of the aerosol generating device.

[0061] As one example, please see Figure 5 The aerosol generating device includes nine display units 20, including first LED lights D1 to D36 and second LED lights D37 to D72. The first LED lights D1 to D36 are red LEDs, and the second LED lights D37 to D72 are blue LEDs.

[0062] Specifically, the cathodes of the first LEDs D1 to D16 are electrically connected to the enable pin COM0 of the touch controller 30; the anodes of the first LEDs D1 to D4 are electrically connected to the detection pin SEG0 of the touch controller 30; the anodes of the first LEDs D5 to D8 are electrically connected to the detection pin SEG1 of the touch controller 30; the anodes of the first LEDs D9 to D12 are electrically connected to the detection pin SEG2 of the touch controller 30; and the anodes of the first LEDs D13 to D16 are electrically connected to the detection pin SEG3 of the touch controller 30. The cathodes of the first LEDs D17 to D36 are electrically connected to the enable pin COM1 of the touch controller 30; the anodes of the first LEDs D17 to D20 are electrically connected to the detection pin SEG4 of the touch controller 30; the anodes of the first LEDs D21 to D24 are electrically connected to the detection pin SEG5 of the touch controller 30; the anodes of the first LEDs D25 to D28 are electrically connected to the detection pin SEG6 of the touch controller 30; the anodes of the first LEDs D29 to D32 are electrically connected to the detection pin SEG7 of the touch controller 30; and the anodes of the first LEDs D33 to D36 are electrically connected to the detection pin SEG8 of the touch controller 30.

[0063] The cathodes of the second LEDs D37 to D52 are electrically connected to the enable pin COM2 of the touch controller 30; the anodes of the second LEDs D37 to D40 are electrically connected to the detection pin SEG0 of the touch controller 30; the anodes of the second LEDs D41 to D44 are electrically connected to the detection pin SEG1 of the touch controller 30; the anodes of the second LEDs D45 to D48 are electrically connected to the detection pin SEG2 of the touch controller 30; and the anodes of the second LEDs D49 to D52 are electrically connected to the detection pin SEG3 of the touch controller 30. The cathodes of the second LEDs D53 to D72 are electrically connected to the enable pin COM3 of the touch controller 30; the anodes of the second LEDs D53 to D56 are electrically connected to the detection pin SEG4 of the touch controller 30; the anodes of the second LEDs D57 to D60 are electrically connected to the detection pin SEG5 of the touch controller 30; the anodes of the second LEDs D61 to D64 are electrically connected to the detection pin SEG6 of the touch controller 30; the anodes of the second LEDs D65 to D68 are electrically connected to the detection pin SEG7 of the touch controller 30; and the anodes of the second LEDs D69 to D72 are electrically connected to the detection pin SEG8 of the touch controller 30.

[0064] Specifically, the first sub-display unit 21 of the first display unit 20 includes four first LEDs D1 to D4 connected in parallel, and the second sub-display unit 22 of the first display unit 20 includes four second LEDs D37 to D40 connected in parallel, corresponding to the copper foil G1. The first sub-display unit 21 of the second display unit 20 includes four first LEDs D5 to D8 connected in parallel, and the second sub-display unit 22 of the second display unit 20 includes four second LEDs D41 to D44 connected in parallel, corresponding to the copper foil G2. The first sub-display unit 21 of the third display unit 20 includes four first LEDs D9 to D12 connected in parallel, and the second sub-display unit 22 of the third display unit 20 includes four second LEDs D45 to D48 connected in parallel, corresponding to the copper foil G3. The first sub-display unit 21 of the fourth display unit 20 includes four first LEDs D13 to D16 connected in parallel, and the second sub-display unit 22 of the fourth display unit 20 includes four second LEDs D49 to D52 connected in parallel, corresponding to the copper foil G4. The first sub-display unit 21 of the fifth display unit 20 includes four first LEDs D17 to D20 connected in parallel, and the second sub-display unit 22 of the fifth display unit 20 includes four second LEDs D53 to D56 connected in parallel, corresponding to the copper foil G5. The first sub-display unit 21 of the sixth display unit 20 includes four first LEDs D21 to D24 connected in parallel, and the second sub-display unit 22 of the sixth display unit 20 includes four second LEDs D57 to D60 connected in parallel, corresponding to the copper foil G6. The first sub-display unit 21 of the seventh display unit 20 includes four first LEDs D25 to D28 connected in parallel, and the second sub-display unit 22 of the seventh display unit 20 includes four second LEDs D61 to D64 connected in parallel, corresponding to the copper foil G7. The first sub-display unit 21 of the eighth display unit 20 includes four first LEDs D29 to D32 connected in parallel, and the second sub-display unit 22 of the eighth display unit 20 includes four second LEDs D65 to D68 connected in parallel, corresponding to the copper foil G8. The first sub-display unit 21 of the ninth display unit 20 includes four first LEDs D33 to D36 connected in parallel, and the second sub-display unit 22 of the eighth display unit 20 includes four second LEDs D69 to D72 connected in parallel, corresponding to the copper foil G9.

[0065] For example, touching the copper foil G1 illuminates the first display unit 20, indicating that a "chess piece" has been placed at the corresponding position on the 3x3 grid "chessboard". Specifically, the detection pin SEG0 outputs a high-level signal, and the enable pin COM0 outputs a low-level signal, illuminating the first LEDs D1 to D4; or, the detection pin SEG0 outputs a high-level signal, and the enable pin COM2 outputs a low-level signal, illuminating the second LEDs D37 to D40.

[0066] The touch controller 30 includes multiple detection pins 301 and multiple enable pins 302. Each detection pin 301 is electrically connected to a corresponding sensing electrode 10 to obtain the capacitance value of the sensing capacitor. Each detection pin 301 and each enable pin 302 are electrically connected to a corresponding display unit 20.

[0067] By electrically connecting each detection pin 301 to the corresponding sensing electrode 10 and display unit 20, the detection pin 301 is reused, saving the pin resources of the touch controller 30, thereby simplifying the hardware design of the touch controller 30 and reducing hardware costs.

[0068] The touch controller 30 is configured to periodically detect changes in the capacitance value of the sensing capacitor through the detection pin 301, and determine whether the sensing electrode 10 corresponding to the detection pin 301 is touched based on the changes in the capacitance value. If the sensing electrode 10 is touched, the detection pin 301 is controlled to output a first level signal and the corresponding enable pin 302 is controlled to output a second level signal, so that the display unit 20 corresponding to the sensing electrode 10 displays a preset pattern.

[0069] In this embodiment, the touch detection of the sensing electrode 10 and the display control of the display unit 20 adopt the time-division multiplexing principle. For example, the scan period T is 10ms. The touch controller 30 periodically executes the scan period T, defining the first 5ms of the scan period as the touch detection time. During the touch detection time, the change in capacitance value of the detection pin 301 is detected, and the change in capacitance value determines whether the sensing electrode 10 corresponding to the detection pin 301 has been touched. The last 5ms of the scan period T is defined as the display control time. If the sensing electrode 10 is touched, the detection pin 301 is controlled to output a first-level signal, and the corresponding enable pin 302 is controlled to output a second-level signal, thereby controlling the display unit 20 corresponding to the sensing electrode 10 to display a preset pattern during the display control time of the scan period. When the touch controller 30 executes at high speed, the touch detection of the sensing electrode 10 and the display control of the display unit 20 appear to operate simultaneously.

[0070] In some embodiments, the touch controller 30 is also configured to control a plurality of display units 20 to alternately display a first preset pattern and a second preset pattern.

[0071] In one example, multiple display units 20 alternately displaying a first preset pattern and a second preset pattern includes: upon the first touch, the first sub-display unit 21 is illuminated, displaying the first preset pattern; upon subsequent touches, the second sub-display unit 22 and the first sub-display unit 21 are alternately illuminated, alternately displaying the second preset pattern and the first preset pattern. Alternatively, upon the first touch, the second sub-display unit 22 is illuminated, displaying the second preset pattern; upon subsequent touches, the first sub-display unit 21 and the second sub-display unit 22 are alternately illuminated, alternately displaying the first preset pattern and the second preset pattern. Wherein, upon the first touch, the first sub-display unit 21 is illuminated, displaying the first preset pattern, includes: pre-setting the first sub-display unit 21 to illuminate and display the first preset pattern upon the first touch; or the first sub-display unit 21 and the second sub-display unit 22 alternately appear upon the first touch, and a subsequent touch determines that the first sub-display unit 21 is illuminated, displaying the first preset pattern. The second sub-display unit 22 is lit up upon the first touch, and the second preset pattern is displayed. This includes: the second sub-display unit 22 is lit up upon the first touch, and the second preset pattern is displayed; or the first sub-display unit 21 and the second sub-display unit 22 alternately appear upon the first touch, and the second sub-display unit 22 is lit up upon a second touch, and the second preset pattern is displayed.

[0072] Please see Figure 3 The touch controller 30 includes multiple registers 31, each of which corresponds to a detection pin 301. The touch controller 30 is also configured to configure the flag bits of the registers according to the change in capacitance value, and to control the display unit 20 to display or not display a preset pattern according to the corresponding flag bits.

[0073] In one embodiment, the touch control chip U1 continuously monitors the capacitance values ​​of multiple detection pins 301 for changes. If the capacitance value of a detection pin 301 increases or the change exceeds a preset threshold, it is considered that the sensing electrode 10 corresponding to that detection pin 301 has been touched, and the flag bit of the register 31 corresponding to the detection pin 301 is configured to a binary value of 1. If the capacitance value of a detection pin 301 does not change or the change is less than the preset threshold, it is considered that the sensing electrode 10 corresponding to that detection pin 301 has not been touched, and the flag bit of the register 31 corresponding to the detection pin 301 is configured to a binary value of 0. By reading the flag bit value of the register 31, the touch control chip U1 can determine the touch state of the sensing electrode 10, and thus control the display unit 20 to display a preset pattern.

[0074] Based on the above embodiments, the touch control chip U1 has an anti-interference algorithm. After detecting the capacitance value of the detection pin 301, the anti-interference algorithm is used to filter the capacitance value, and the change in the filtered capacitance value determines that the sensing electrode 10 corresponding to the detection pin 301 has been touched.

[0075] Please see Figure 6 The touch controller 30 includes a touch control chip U1 and its peripheral circuitry. The touch control chip U1 includes detection pins SEG0 to SEG8, enable pins COM0 to COM3, pin BUSY, pin DATA, pin RL ADC, pin USB CHECK, pin CHG EN, pin PWM ADJ, pin RL DET, pin SMOKE KEY, pin SPK EN, pin I CPCK, pin I CPDA, and pin KEY. The peripheral circuitry is a filter circuit, including resistor R1, capacitor C1, and capacitor C2, and their connection relationship is shown in the figure.

[0076] The aerosol generating apparatus provided in this application includes multiple sensing electrodes, multiple display units, and a touch controller. Each sensing electrode forms a sensing capacitor with a power ground terminal. Each display unit corresponds to one sensing electrode, and each display unit is configured to display two different preset patterns. The touch controller includes multiple detection pins and multiple enable pins. Each detection pin is connected to a corresponding sensing electrode to obtain the capacitance value of the sensing capacitor. Each detection pin and each enable pin are electrically connected to a corresponding display unit. The touch controller is configured to periodically detect changes in the capacitance value of the sensing capacitor through the detection pins and determine whether the sensing electrode corresponding to the detection pin has been touched based on the change in capacitance value. If the sensing electrode is touched, the controller controls the detection pin to output a first-level signal and the corresponding enable pin to output a second-level signal, thereby causing the display unit corresponding to the sensing electrode to display the preset pattern. Therefore, this application embodiment uses multiple sensing electrodes, multiple display units, and a touch controller to replace a display screen for display, which can reduce the cost of the aerosol generating apparatus.

[0077] Please refer to it again. Figure 3 The aerosol generating device also includes a switching circuit 40, a sound effect circuit 50, an airflow sensor 60, a power regulation circuit 70, and a power supply circuit 80. It is understood that in some aerosol generating devices, the sound effect circuit 50 and / or the power regulation circuit 70 may be omitted.

[0078] The switch circuit 40 has at least two different switch positions. The switch circuit 40 is electrically connected to the touch controller 30. The switch circuit 40 is configured to output a corresponding switch signal according to the switch position. The touch controller 30 is also configured to control the aerosol generating device to work in different game modes based on the switch signal, or to control the aerosol generating device to exit the game mode.

[0079] The game modes include player-versus-AI mode and two-player mode.

[0080] In one embodiment, see Figure 7 The switch circuit 40 is electrically connected to the pin KEY of the touch control chip U1. The switch circuit 40 includes resistors R11, R12, R13 to R17, bidirectional diode D82, and toggle switch S1. The connection relationship is shown in the figure.

[0081] The toggle switch S1 has three different switch positions. When the toggle switch S1 is switched to the first switch position, it outputs a first voltage signal and sends it to the pin KEY of the touch control chip U1. The touch controller 30 is also configured to control the aerosol generator to work in the two-player battle mode with the first voltage signal. When the toggle switch S1 is switched to the second switch position, it outputs a second voltage signal and sends it to the pin KEY of the touch control chip U1. The touch controller 30 is also configured to control the aerosol generator to work in the human-computer battle mode with the second voltage signal. When the toggle switch S1 is switched to the third switch position, it outputs a third voltage signal and sends it to the pin KEY of the touch control chip U1. The touch controller 30 is also configured to control the aerosol generator to exit the game mode with the third voltage signal.

[0082] The sound effect circuit 50 is electrically connected to the touch controller 30, which is also configured to control the sound effect circuit 50 to emit corresponding sound effects when the aerosol generating device enters game mode, exits game mode, and the display unit 20 displays a preset pattern.

[0083] In one embodiment, see Figure 8 The audio circuit 50 includes a voice chip U2, capacitors C4 to C6, resistors R18 and R19, and a PMOS transistor Q1, with the connections shown in the figure. The voice chip U2 includes pins BUSY, DATA, SI, CLK, PWMP, and PWMN. Pin BUSY of the voice chip U2 is electrically connected to pin BUSY of the touch control chip U1, and pin DATA of the voice chip U2 is also electrically connected to pin DATA of the touch control chip U1. Pins SI and CLK are left floating, and pins PWMP and PWMN are electrically connected to the speaker (not shown in the figure).

[0084] The audio source files for the sound effects corresponding to the aerosol generator entering game mode, exiting game mode, and the display unit 20 displaying preset patterns are pre-converted into BIN files and burned into the voice chip U2. When the aerosol generator enters game mode, the touch control chip U1 outputs sound effect command 1, and the sound effect circuit 50 emits the corresponding sound effect based on sound effect command 1; when the aerosol generator exits game mode, the touch control chip U1 outputs sound effect command 2, and the sound effect circuit 50 emits the corresponding sound effect based on sound effect command 2; when the display unit 20 displays according to preset rules, the touch control chip U1 outputs sound effect command 3, and the sound effect circuit 50 emits the corresponding sound effect based on sound effect command 3.

[0085] In some embodiments, the touch controller 30 is also configured to control the sound circuit 50 to emit corresponding sound effects when the aerosol generating device enters different game modes.

[0086] The airflow sensor 60 is electrically connected to the touch controller 30. The airflow sensor 60 is configured to output a suction signal in response to a suction action. The touch controller 30 is also configured to activate the aerosol generating device based on the suction signal.

[0087] In one embodiment, see Figure 9 The airflow sensor 60 is electrically connected to the SMOKE KEY pin of the touch control chip U1. The airflow sensor 60 includes a microphone U3, a resistor R20, and a capacitor C7, as shown in the figure. The microphone U3 outputs a fourth voltage signal in response to the suction action and sends it to the SMOKE KEY pin of the touch control chip U1. The touch controller 30 starts the aerosol generation device based on the fourth voltage signal.

[0088] The power regulation circuit 70 is electrically connected to the touch controller 30, and the power regulation circuit 70 is configured to control the output power of the aerosol generating device based on the power regulation command sent by the touch controller 30.

[0089] In one embodiment, see Figure 10 The power adjustment circuit 70 is electrically connected to the pins RLADC, PWM ADJ and RL DET of the touch control chip U1, respectively. The power adjustment circuit 70 includes contact D+1, contact D-1, resistors R21 to R26, capacitor C8, PMOS transistor Q2 and PMOS transistor Q3. The connection relationship is shown in the figure. Contacts D+1 and D-1 are electrically connected to the heating wire (not shown in the figure).

[0090] Based on the above embodiment, the touch controller 30 detects the suction action applied by the user to the airflow sensor 60. The PWM ADJ pin of the touch control chip U1 outputs a high level, which does not meet the conduction condition of PMOS transistor Q2, so PMOS transistor Q2 is turned off. The RL DET pin of the touch control chip U1 outputs a low level, which meets the conduction condition of PMOS transistor Q3, so PMOS transistor Q3 is turned on. At this time, the current loop of PMOS transistor Q3 and heating wire is selected. Then, the resistance of the heating wire is detected by the RL ADC of the touch control chip U1. The touch control chip U1 calculates the cell voltage under load based on the internal reference voltage, and calculates the duty cycle of the output PWM signal based on the resistance of the heating wire and the cell voltage. The PWM ADJ pin of the touch control chip U1 outputs a power adjustment command to adjust the duty cycle of the PWM signal, thereby keeping the output power of the aerosol generating device constant and avoiding the impact of cell voltage decrease and heating wire resistance change on the output power as usage time increases.

[0091] The power supply circuit 80 is electrically connected to the touch controller 30, the switch circuit 40, the sound effect circuit 50, the airflow sensor 60, and the power regulation circuit 70, respectively, to provide power.

[0092] In one embodiment, the power supply circuit 80 includes a battery cell for providing power. The battery cell can be any suitable power source, such as a DC source, or a battery. In one example, the battery is a lithium-ion battery, or it can be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery.

[0093] Optionally, the power supply circuit 80 also includes a protection circuit electrically connected to the battery cell to protect the battery cell.

[0094] When the power supply circuit 80 includes a rechargeable battery cell, the power supply circuit 80 also includes an interface circuit and a charging circuit. The interface circuit is configured to receive the input voltage from the charging device and is electrically connected to the touch controller 30. The charging circuit is electrically connected to the interface circuit, the touch controller 30, and the rechargeable battery cell, respectively, and is used to convert the input voltage into a charging voltage for charging the rechargeable battery cell.

[0095] Please refer to it again. Figure 3 The aerosol generating device also includes multiple electrostatic discharge (ESD) protection circuits 90, each electrically connected to a corresponding detection pin 301 to prevent ESD damage to the detection pin 301. And / or, the aerosol generating device also includes multiple anti-interference circuits 100, each electrically connected between a corresponding sensing electrode 10 and display unit 20 to prevent mutual interference between the sensing electrode 10 and display unit 20.

[0096] In one embodiment, see Figure 6 The aerosol generating device also includes nine electrostatic protection circuits 90, including resistors R2 to R10, with the connection relationship shown in the figure, which serve to protect the detection pin 301 of the touch control chip U1. The aerosol generating device also includes nine anti-interference circuits 100, including diodes D73 to D81, with the connection relationship shown in the figure, to prevent mutual interference between the touch detection of the sensing electrode 10 and the display control of the display unit 20 during time-division multiplexing.

[0097] Please see Figure 11 The touch display method provided in this application is applied to an aerosol generating apparatus as described in any embodiment of this application, such as... Figure 11 As shown, the method includes:

[0098] Step S110: Periodically detect the change in capacitance value of the sensing capacitor through the detection pin.

[0099] Step S120: Determine whether the sensing electrode corresponding to the detection pin has been touched based on the change in capacitance value.

[0100] In step S130, if the sensing electrode is touched, the detection pin is controlled to output a first-level signal and the corresponding enable pin is controlled to output a second-level signal, thereby causing the display unit corresponding to the sensing electrode to display a preset pattern. In some embodiments, the preset pattern includes a first preset pattern and a second preset pattern, and the method further includes controlling a plurality of display units to alternately display the first preset pattern and the second preset pattern.

[0101] The first and second preset patterns are used to represent the "pieces" held by the two players respectively. The players take turns touching (clicking) the empty display units, that is, the first and second preset patterns are displayed alternately. Among them, the display units that do not display the first or second preset pattern are empty display units.

[0102] In some embodiments, the method further includes: controlling the detection pin to detect the capacitance value of the sensing capacitor during a first time period of the scanning cycle, and controlling the detection pin to output a first level signal and the corresponding enable pin to output a second level signal during a second time period following the scanning cycle, so that the display unit corresponding to the sensing electrode displays a preset pattern.

[0103] The detection pin employs a time-division multiplexing principle. During the first time interval of the scan cycle, the detection pin is controlled to detect the capacitance value of the sensing capacitor, thereby realizing touch detection of the sensing electrode 10. During the second time interval following the scan cycle, the detection pin is controlled to output a first-level signal and the corresponding enable pin outputs a second-level signal, thereby causing the display unit corresponding to the sensing electrode to display a preset pattern, thus realizing display control of the display unit 20. Therefore, by multiplexing the detection pin 301, the pin resources of the touch controller 30 are saved, thereby simplifying the hardware design of the touch controller 30 and reducing hardware costs.

[0104] In some embodiments, the aerosol generating device further includes a switching circuit having at least two different switching positions. The switching circuit is electrically connected to a touch controller and is configured to output a corresponding switching signal according to the switching position. The method further includes: controlling the aerosol generating device to operate in different game modes based on the switching signals, or controlling the aerosol generating device to exit a game mode. The game modes include a human-computer battle mode and a two-player battle mode.

[0105] In some embodiments, in human-computer battle mode or two-player battle mode, the method further includes: recording the display order of the display units; when the number of display units is one more than a first preset number, controlling the display unit with the smallest value in the display order to turn off, so that at most only the first preset number of display units can be displayed at the same time.

[0106] In one embodiment, the two players take turns touching the screen, with a maximum of six display units on the screen at any given time (i.e., the screen only displays the six most recent "pieces"). When the sixth display unit is lit up (i.e., when the sixth "piece" is placed), the first display unit dims (the first "piece" dims); when the seventh display unit is lit up (i.e., when the seventh "piece" is placed), the first display unit disappears (the first "piece" disappears), and the second display unit dims (the second "piece" dims); when the eighth display unit is lit up (i.e., when the eighth "piece" is placed), the second display unit disappears (the second "piece" disappears), and the third display unit dims (the third "piece" dims); and so on, until one side wins, thus realizing an infinite tic-tac-toe game.

[0107] In some embodiments, the preset pattern includes a first preset pattern and a second preset pattern, and the method further includes: determining whether the consecutive first preset pattern or second preset pattern has reached a second preset number in the straight line direction; if so, controlling the first preset pattern or second preset pattern in the straight line direction to flash the second preset number until any sensing electrode is touched.

[0108] In one embodiment, the first preset pattern is “×” and the second preset pattern is “○”. The side that first connects three “×” or “○” in a line wins. The three “×” or “○” in a line flash. Touch any position on the screen to restart the game, or exit the game mode by controlling the aerosol generating device through the switch circuit.

[0109] like Figure 12a and Figure 12b As shown, multiple display units are constructed into a 3x3 grid "chessboard". For example, the aerosol generating device is controlled by a switch signal to operate in a two-player mode. Assuming one player's "piece" is a red "○" and the other player's "piece" is a blue "×", the red "○" moves first, and the player who first connects three red "○"s or blue "×"s in a line wins.

[0110] like Figure 12a As shown, one player places their first "piece" in the second row, second column of the 3x3 grid, displaying a red "○" and recording it as the first display unit. The other player then places their second "piece" in the first row, second column of the 3x3 grid, displaying a blue "×" and recording it as the second display unit. In the second round, one player places their third "piece" in the first row, third column of the 3x3 grid, displaying a red "○" and recording it as the third display unit. The other player then places their third "piece" in the third row, first column of the 3x3 grid. When the fourth "piece" is placed in the display unit of the column, a blue "×" is displayed, and it is recorded as the fourth display unit. In the third round, one player places the fifth "piece" in the display unit of the second row and third column of the 3x3 grid, which is displayed as a red "○", and it is recorded as the fifth display unit. Then the other player places the sixth "piece" in the display unit of the second row and first column of the 3x3 grid, which is displayed as a blue "×", and it is recorded as the sixth display unit. At this time, the first "piece" in the display unit of the second row and second column of the 3x3 grid, the red "○", becomes dark.

[0111] like Figure 12b As shown, in the fourth round, one player places their 7th piece in the third row, third column of the 3x3 grid "chessboard," displaying a red "○," which is recorded as the 7th display unit. At this time, the red "○" of the first piece in the second row, second column of the 3x3 grid "chessboard" disappears, and the blue "×" of the second piece in the first row, second column of the 3x3 grid "chessboard" dims. Simultaneously, three red "○"s in the third column of the 3x3 grid "chessboard" form a line and flash. The player represented by the red "○" wins. Touching any display unit of the 3x3 grid "chessboard" clears all the pieces and restarts the game.
