[0040] Referring to Figure 1 The present application provides an embodiment of an aerosol generating device, which comprises a plurality of induction electrodes 10, a plurality of display units 20 and a touch controller 30.

[0041] An induction capacitance is formed between the induction electrode 10 and the power ground.

[0042] In one embodiment, the induction electrode 10 comprises a copper foil electrically connected to a corresponding detection pin 301.

[0043] The copper foil can be deposited on a printed circuit board, and the copper foil mainly senses human touch based on the principle of capacitive induction. Specifically, when the human body does not touch or approach the copper foil, the induction capacitance formed between the copper foil and the ground is small; when the human body touches or approaches the copper foil, the induction capacitance formed between the copper foil and the ground is large.

[0044] In one embodiment, referring to Figure 4 and Figure 6 The aerosol generating device comprises nine induction 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. Among them, the copper foil G1 is electrically connected to the detection pin SEG0 of the touch controller 30 through the pin TK0, the copper foil G2 is electrically connected to the detection pin SEG1 of the touch controller 30 through the pin TK1, the copper foil G3 is electrically connected to the detection pin SEG2 of the touch controller 30 through the pin TK2, the copper foil G4 is electrically connected to the detection pin SEG3 of the touch controller 30 through the pin TK3, the copper foil G5 is electrically connected to the detection pin SEG4 of the touch controller 30 through the pin TK4, the copper foil G6 is electrically connected to the detection pin SEG5 of the touch controller 30 through the pin TK5, the copper foil G7 is electrically connected to the detection pin SEG6 of the touch controller 30 through the pin TK6, the copper foil G8 is electrically connected to the detection pin SEG7 of the touch controller 30 through the pin TK7, and the copper foil G9 is electrically connected to the detection pin SEG8 of the touch controller 30 through the pin TK8.

[0045] For example, the copper foil G1, the copper foil G2, the copper foil G3, the copper foil G4, the copper foil G5, the copper foil G6, the copper foil G7, the copper foil G8 and the copper foil G9 are circular and have the same size. The nine circular copper foils are arranged in a matrix of three rows and three columns, and the adjacent two rows or two columns of copper foils are equally spaced to form a corresponding induction electrode 10 of a nine-square "chessboard".

[0046] The display unit 20 corresponds to the induction electrode 10 one by one, and each display unit 20 is configured to be able to display two different preset patterns.

[0047] Referring to 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 LED lights 210 connected in parallel, and the first sub-display unit 21 is configured to display a first preset pattern. The second sub-display unit 22 includes a plurality of second LED lights 220 connected in parallel, and the second sub-display unit 22 is configured to display a second preset pattern, which is different from the first preset pattern.

[0048] Correspondingly, the display unit 20 is configured as a nine-square "chessboard", and the first sub-display unit 21 and the second sub-display unit 22 are used to represent a "chess piece" of one of the two parties in the game. When the first sub-display unit 21 or the second sub-display unit 22 is lit, it indicates that a "chess piece" is dropped at the corresponding position of the nine-square "chessboard". The first preset pattern is formed by the layout of the plurality of first LED lights 210 connected in parallel, and the second preset pattern is formed by the layout of the plurality of second LED lights 220 connected in parallel. For example, the first preset pattern is "O", and the second preset pattern is "X".

[0049] It can be understood that the number of first LED lights 210 in the first sub-display unit 21 can be determined according to the first preset pattern and the hardware parameters of the touch controller 30, etc. The number of second LED lights 220 in the second sub-display unit 22 can be determined according to the second preset pattern and the hardware parameters of the touch controller 30, etc.

[0050] In one embodiment, the colors of the first LED lights 210 and the second LED lights 220 are different. By setting the colors of the first LED lights 210 and the second LED lights 220 to be different, the two parties in the game can be better distinguished.

[0055] Specifically, the first sub-display unit 21 of the first display unit 20 includes four first LED lamps D1 to D4 connected in parallel, and the second sub-display unit 22 of the first display unit 20 includes four second LED lamps 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 LED lamps D5 to D8 connected in parallel, and the second sub-display unit 22 of the second display unit 20 includes four second LED lamps D41 to D44 connected in parallel, corresponding to the copper foil G2.

[0056] For example, when the copper foil G1 is touched, the first display unit 20 is lighted, indicating that a "chess piece" is dropped at the corresponding position of the nine-square "chessboard". Specifically, the detection pin SEG0 outputs a high-level signal, and the enable pin COM0 outputs a low-level signal, so that the first LED lamp D1 to the first LED lamp D4 are lighted; or the detection pin SEG0 outputs a high-level signal, and the enable pin COM2 outputs a low-level signal, so that the second LED lamp D37 to the second LED lamp D40 are lighted.

[0057] The touch controller 30 includes a plurality of detection pins 301 and a plurality of enable pins 302. Each detection pin 301 is electrically connected to a corresponding sensing electrode 10, for obtaining the capacitance value of the sensing capacitor; and each detection pin 301 and each enable pin 302 are electrically connected to a corresponding display unit 20.

[0058] By electrically connecting each detection pin 301 to a corresponding sensing electrode 10 and display unit 20 respectively, the multiplexing of the detection pin 301 is realized, the pin resources of the touch controller 30 are saved, so that the hardware design of the touch controller 30 can be simplified, and the hardware cost is reduced.

[0059] In the embodiment of the present application, 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 scanning period T is 10 ms, and the touch controller 30 periodically performs the scanning period T. The first 5 ms of the scanning period T is defined as the touch detection time of the scanning period, and the change of the capacitance value of the detection pin 301 is detected in the touch detection time of the scanning period, and whether the sensing electrode 10 corresponding to the detection pin 301 is touched is judged according to the change of the capacitance value. The last 5 ms of the scanning period T is defined as the display control time of the scanning period, and if the sensing electrode 10 is touched, the detection pin 301 outputs a first level signal and the corresponding enable pin 302 outputs a second level signal, so as to control the display unit 20 corresponding to the sensing electrode 10 to display a preset pattern in the display control time of the scanning period. When the touch controller 30 works at high speed, the touch detection of the sensing electrode 10 and the display control of the display unit 20 seem to work at the same time.

[0060] In the embodiment of the present application, 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 scanning period T is 10 ms, and the touch controller 30 periodically performs the scanning period T. The first 5 ms of the scanning period T is defined as the touch detection time of the scanning period, and the change of the capacitance value of the detection pin 301 is detected in the touch detection time of the scanning period, and whether the sensing electrode 10 corresponding to the detection pin 301 is touched is judged according to the change of the capacitance value. The last 5 ms of the scanning period T is defined as the display control time of the scanning period, and if the sensing electrode 10 is touched, the detection pin 301 outputs a first level signal and the corresponding enable pin 302 outputs a second level signal, so as to control the display unit 20 corresponding to the sensing electrode 10 to display a preset pattern in the display control time of the scanning period. When the touch controller 30 works at high speed, the touch detection of the sensing electrode 10 and the display control of the display unit 20 seem to work at the same time.

[0061] In some embodiments, the touch controller 30 is further configured to control the plurality of display units 20 to alternately display the first preset pattern and the second preset pattern.

[0062] In one example, the plurality of display units 20 alternately displaying the first preset pattern and the second preset pattern comprises: the first time the first sub-display unit 21 is lit, displaying the first preset pattern, and the subsequent touch alternately lights up the second sub-display unit 22 and the first sub-display unit 21, alternately displaying the second preset pattern and the first preset pattern. Alternatively, the second sub-display unit 22 is lit the first time, displaying the second preset pattern, and the subsequent touch alternately lights up the first sub-display unit 21 and the second sub-display unit 22, alternately displaying the first preset pattern and the second preset pattern. Wherein the first time the first sub-display unit 21 is lit, displaying the first preset pattern comprises: presetting the first time the first sub-display unit 21 is lit, displaying the first preset pattern; or the first time the first sub-display unit 21 and the second sub-display unit 22 appear alternately, and the first sub-display unit 21 is determined to be lit by touching again, displaying the first preset pattern. The second sub-display unit 22 is lit the first time, displaying the second preset pattern, which comprises: presetting the first time the second sub-display unit 22 is lit, displaying the second preset pattern; or the first time the first sub-display unit 21 and the second sub-display unit 22 appear alternately, and the second sub-display unit 22 is determined to be lit by touching again, displaying the second preset pattern.

[0063] Please refer to Figure 3 , the touch controller 30 comprises a plurality of registers 31, the register 31 corresponds to the detection pin 301 one by one, and the touch controller 30 is further configured to configure the flag bit of the register according to the change of the capacitance value, and control the display unit 20 to display or not to display the preset pattern according to the corresponding flag bit.

[0064] In one embodiment, the touch control chip U1 inside detects whether the capacitance value of the plurality of detection pins 301 changes all the time, if it is detected that the capacitance value of the detection pin 301 increases or the capacitance value changes is greater than a preset threshold, it is considered that the sensing electrode 10 corresponding to the detection pin 301 is touched, then the flag bit of the register 31 corresponding to the detection pin 301 is configured to binary value 1, if it is detected that the capacitance value of the detection pin 301 does not change or the capacitance value changes is less than a preset threshold, it is considered that the sensing electrode 10 corresponding to the detection pin 301 is not touched, then the flag bit of the register 31 corresponding to the detection pin 301 is configured to binary value 0. The touch control chip U1 can determine the touch state of the sensing electrode 10 by reading the flag bit value of the register 31, and then can control the display unit 20 to display the preset pattern.

[0065] On the basis of the above-mentioned embodiment, 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 for filtering processing of the capacitance value, and the change of the capacitance value after the filtering processing is used to judge whether the sensing electrode 10 corresponding to the detection pin 301 is touched.

The touch controller is configured to periodically detect the change of the capacitance value of the sensing capacitor through the detection pin, and determine whether the sensing electrode corresponding to the detection pin is touched according to the change of the capacitance value. If the sensing electrode is touched, the touch controller controls the detection pin to output a first level signal and the corresponding enable pin to output a second level signal, so that the display unit corresponding to the sensing electrode displays a preset pattern. Therefore, the embodiment of the present application displays by using a plurality of sensing electrodes, a plurality of display units, and a touch controller instead of a display screen, which can reduce the cost of the aerosol generating device.

The aerosol-generating device further comprises nine anti-interference circuits 100, including diodes D73 to D81, which are connected as shown in the figure, and prevent the touch detection of the induction electrode 10 and the display control of the display unit 20 from interfering with each other when time division multiplexing.

[0088] Please refer to Figure 11 The touch display method provided by the embodiments of the present application is applied to the aerosol-generating device as in any of the embodiments of the present application, as shown in Figure 11 The method comprises the following steps:

[0089] In step S110, the change in the capacitance value of the induction capacitor is detected periodically through the detection pin.

[0090] In step S120, it is determined whether the induction electrode corresponding to the detection pin is touched according to the change in the capacitance value.

[0091] In step S130, if the induction 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, so that the display unit corresponding to the induction electrode displays a preset pattern. In some embodiments, the preset pattern comprises a first preset pattern and a second preset pattern, and the method further comprises: controlling the plurality of display units to display the first preset pattern and the second preset pattern alternately.

[0092] The first preset pattern and the second preset pattern are used to represent the "chess pieces" held by the two parties in a game, and the two parties take turns to touch (click) the idle display units, i.e., the first preset pattern and the second preset pattern are displayed alternately. The display units that do not display the first preset pattern or the second preset pattern are idle display units.

[0093] In some embodiments, the method further comprises: controlling the detection pin to detect the capacitance value of the induction capacitor in a first time period of a scanning period, and controlling the detection pin to output a first-level signal and the corresponding enable pin to output a second-level signal in a second time period that is continuous with the scanning period, so that the display unit corresponding to the induction electrode displays a preset pattern.

[0094] The detection pin adopts time division multiplexing principle. In the first time period of the scanning cycle, the detection pin is controlled to detect the capacitance value of the sensing capacitor, so as to realize touch detection of the sensing electrode 10. In the second time period of the scanning cycle, the detection pin is controlled to output a first level signal and the corresponding enable pin is controlled to output a second level signal, so that the corresponding display unit of the sensing electrode displays a preset pattern, thereby realizing display control of the display unit 20. Therefore, through multiplexing of 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 the hardware cost.

[0095] In some embodiments, the aerosol generating device further comprises a switch circuit having at least two different switch positions, the switch circuit being electrically connected with the touch controller, the switch circuit being configured to output a corresponding switch signal according to the switch position, and the method further comprises: controlling the aerosol generating device to work in different game modes or to exit the game mode based on the switch signal. The game modes include a man-machine combat mode and a two-player combat mode.

[0096] In some embodiments, in the man-machine combat mode or the two-player combat mode, the method further comprises: recording the display order of the display units; when the number of the display units is one more than the first preset number, controlling the display unit with the smallest value in the display order to be turned off, so that at most the first preset number of display units are displayed at the same time.

[0097] As one of the embodiments, the two players take turns to touch the screen, and at most 6 display units on the screen are displayed at the same time (i.e., the screen displays only the last 6 "chess pieces"). When the 6th display unit is lit (i.e., the 6th "chess piece" is dropped), the 1st display unit is dimmed (the 1st "chess piece" is dimmed); when the 7th display unit is lit (i.e., the 7th "chess piece" is dropped), the 1st display unit disappears (the 1st "chess piece" disappears), and the 2nd display unit is dimmed (the 2nd "chess piece" is dimmed); when the 8th display unit is lit (i.e., the 8th "chess piece" is dropped), the 2nd display unit disappears (the 2nd "chess piece" disappears), and the 3rd display unit is dimmed (the 3rd "chess piece" is dimmed); and so on, until one side wins, thereby realizing an infinite tic-tac-toe game.

[0098] In some embodiments, the preset pattern includes a first preset pattern and a second preset pattern, and the method further comprises: determining whether the continuous first preset pattern or second preset pattern reaches a second preset number in a straight line direction; if so, controlling the second preset number of the first preset pattern or the second preset pattern in the straight line direction to flash until any one of the sensing electrodes is touched.

[0099] As one of the embodiments, the first preset pattern is "X", the second preset pattern is "O", the party that connects 3 "X" or "O" into a line first wins, the 3 "X" or "O" connected into a line flashes, the game is restarted by touching any position of the screen, or the aerosol generating device exits the game mode by the switch circuit control.

[0100] As shown in Figure 12a and Figure 12b , the plurality of display units are configured as a nine-square "chessboard". For example, based on the switch signal, the aerosol generating device is controlled to work in the two-player mode, assuming that the "chess piece" of one party is red "O" and the "chess piece" of the other party is blue "X", the red "O" goes first, and the party that connects 3 red "O" or blue "X" into a line first wins.

[0101] As shown in Figure 12a , the party drops the first "chess piece" in the display unit of the second row and the second column of the nine-square "chessboard", displays the red "O", and records it as the first display unit; then the other party drops the second "chess piece" in the display unit of the first row and the second column of the nine-square "chessboard", displays the blue "X", and records it as the second display unit; in the second round, the party drops the third "chess piece" in the display unit of the first row and the third column of the nine-square "chessboard", displays the red "O", and records it as the third display unit; then the other party drops the fourth "chess piece" in the display unit of the third row and the first column of the nine-square "chessboard", displays the blue "X", and records it as the fourth display unit; in the third round, the party drops the fifth "chess piece" in the display unit of the second row and the third column of the nine-square "chessboard", displays the red "O", and records it as the fifth display unit; then the other party drops the sixth "chess piece" in the display unit of the second row and the first column of the nine-square "chessboard", displays the blue "X", and records it as the sixth display unit, at this time, the first "chess piece" of the red "O" in the display unit of the second row and the second column of the nine-square "chessboard" becomes dim.

[0102] As shown in Figure 12b , in the fourth round, the party drops the seventh "chess piece" in the display unit of the third row and the third column of the nine-square "chessboard", displays the red "O", and records it as the seventh display unit, at this time, the first "chess piece" of the red "O" in the display unit of the second row and the second column of the nine-square "chessboard" disappears, the second "chess piece" of the blue "X" in the display unit of the first row and the second column of the nine-square "chessboard" becomes dim, at the same time, 3 red "O" in the third column of the nine-square "chessboard" are connected into a line, the 3 red "O" flashes, the party represented by the red "O" wins, and the "chess pieces" are all cleared by touching any one of the display units of the nine-square "chessboard" to restart the game.
