[0040] In order to further understand the technical solutions of the electronic cigarette and its double-color display circuit in some embodiments of the present application, the technical solutions of the electronic cigarette and its double-color display circuit, and how the technical solutions solve the above technical problems will be described in detail below in combination with some specific embodiments and drawings. Each embodiment can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0041] In some embodiments, as shown in Figure 1 A double-color display circuit of an electronic cigarette is provided, and the double-color display circuit includes a detection module 101, a touch module 102, a control module 103, a power output module 104, a driving module 105, and a double-color LED lamp module 106.

[0042] The input end of the control module 103 is connected to the output end of the detection module 101 and the output end of the touch module 102 respectively, the output end of the control module 103 is connected to the input end of the power output module 104 and the input end of the driving module 105 respectively, and the output end of the driving module 105 is connected to the input end of the double-color LED lamp module 106.

[0043] The detection module 101 outputs a detection signal when detecting that the air pressure reaches a triggering condition, the touch module 102 acquires and outputs output power information according to a user touch operation to the control module 103, the control module 103 is used for controlling the power output module 104 to output first power and controlling the driving module 105 to drive the double-color LED lamp module 106 to display a first color pattern when receiving the detection signal and the first output power information, and the control module 103 is also used for controlling the power output module 104 to output second power and controlling the driving module 105 to drive the double-color LED lamp module 106 to display a second color pattern when receiving the detection signal and the second output power information.

[0044] The detection module 101 monitors the change of air pressure inside the electronic cigarette to detect whether the user is inhaling. When the air pressure reaches a preset trigger value, a detection signal is output to the control module 103. When the user inhales, the air pressure inside the electronic cigarette decreases, and the detection module 101 senses the pressure change and outputs a detection signal. The touch module 102 obtains the power information set by the user through the touch sensor or button, and transmits the corresponding power information (first power mode or second power mode) to the control module 103 for adjusting the heating power and LED color display. The user selects different power modes (for example, low power mode and high power mode) through touch operation, and the touch module 102 converts the user's selection information into output power information and transmits it to the control module 103. The control module 103 (MCU / processing chip) processes the signals input by the detection module 101 and the touch module 102, obtains the heating power of the electronic cigarette and the LED display color, controls the output of the power output module 104 to provide different heating powers in different power modes, and controls the driving module 105 to make the double-color LED lamp module 106 display different color patterns. When the power output module 104 receives the first power signal from the control module 103, it outputs the first power to provide lower heating power, and when it receives the second power signal from the control module 103, it outputs the second power to provide higher heating power. The driving module 105 drives the double-color LED lamp module 106 to display different color light effects according to the instructions from the control module 103; the control module 103 sends instructions to the driving module 105, which decides the LED light color according to the current power mode. In low power mode, the driving module 105 makes the LED light emit a first color (such as blue), indicating that the electronic cigarette is in a low-temperature working state; in high power mode, the driving module 105 makes the LED light emit a second color (such as red), indicating that the electronic cigarette is in a high-temperature working state. The double-color LED lamp module 106 displays different colors according to the control of the driving module 105, which is used to prompt the user of the current working state of the electronic cigarette. The working process is as follows: the user inhales, the detection module 101 outputs a detection signal, the control module 103 receives the signal, the user sets the power, the touch module 102 outputs the power information, and the control module 103 receives the signal; if the power information is the first power (low power), the control module 103 outputs a low power signal to the power output module 104; if the power information is the second power (high power), the control module 103 outputs a high power signal to the power output module; in low power mode, the driving module 105 makes the LED light display a first color (such as blue); in high power mode, the driving module 105 makes the LED light display a second color (such as red); the power output module 104 outputs the corresponding current power to the heating element according to the instructions from the control module 103, and adjusts the output power to achieve different heating temperatures, meeting the different smoking experience needs of the user.

[0045] The technical effect of the embodiment is that, by combining the detection module 101, the touch module 102, the control module 103, the power output module 104, and the driving module 105, the intelligent switching and intuitive display of the electronic cigarette in the low-power and high-power modes are realized; the detection module 101 accurately identifies the user's inhaling behavior according to the change in air pressure, the touch module 102 allows the user to select the power mode through a simple touch operation, and the control module 103 adjusts the power and LED light display according to the touch input; through the color change of the double-color LED light module 106, the user can clearly identify the current device working state, and at the same time, the power output module provides corresponding heating power according to different modes to optimize the smoking experience. The technical solution improves the interactivity between the user and the device and enhances the user's convenience and visual experience.

[0046] As an embodiment of the detection module 101, as shown in Figure 2 The detection module 101 includes:

[0047] The microphone module 111 is used to generate and output an electrical signal when detecting a change in air pressure.

[0048] The conversion module 112, whose input end is connected to the input end of the microphone module 111 and whose output end is the output end of the detection module 101, is used to output a detection signal when the electrical signal meets the triggering condition.

[0049] The microphone module 111 monitors the change in air pressure inside the electronic cigarette and generates a corresponding electrical signal according to the change in air pressure. When the user inhales, the air pressure inside the electronic cigarette decreases, and the microphone module 111 senses the change in air pressure and converts it into an electrical signal. The conversion module 112 receives the electrical signal output by the microphone module 111 and processes the signal according to the set triggering condition. If the received electrical signal meets the pre-set air pressure change condition (such as the air pressure dropping to a certain specific threshold), the conversion module 112 outputs a detection signal to inform the control module 103 to perform subsequent power adjustment and LED display control.

[0050] As an example, as shown in Figure 3 The microphone module 111 includes a microphone M1, a microphone sensor MICI, a chip U1, and a capacitor C1. The microphone M1 and the microphone sensor MICI constitute an air pressure sensor that can sense the change in air pressure. When the air pressure changes, the air pressure sensor converts the change into an electrical signal. The chip U1 receives the electrical signal from the air pressure sensor. When the air pressure value represented by the electrical signal reaches the pre-set threshold, it is determined that the pre-set condition is met, and a detection signal SMK_WK is output to the control module 103, as shown in Figure 4 The control module 103 is a control chip U0, and the pin 1 of the control chip U0 receives the detection signal SMK_WK.

[0051] As an implementation, as shown in Figure 5 The touch module 102 includes a touch screen 121 and a touch chip 122, the output end of the touch screen 121 is connected to the input end of the touch chip 122, and the output end of the touch chip 122 is the output end of the touch module 102;

[0052] The touch chip 122 detects the number of touches received on the touch screen 121, and switches between outputting the first output power information and the second output power information when the number of touches meets the switching condition, which is a preset number of times within a preset time.

[0053] The touch chip 122 detects the user's touch operation and outputs the corresponding power information according to the number of touches within a preset time, and switches the output of different power information (first output power information and second output power information) in turn through a specific touch action (such as multiple touches in a short time), thereby adjusting the working mode (low power mode or high power mode) of the electronic cigarette. The touch chip 122 detects the user's touch action and starts timing, and the touch chip 122 will monitor the number of touches within a preset time (for example, 1.5 seconds), and when the number of touches is detected to reach a preset number of times (for example, 3 times), the touch chip 122 judges as a switching request. If the number of touches meets the switching condition, the touch chip 122 will output the corresponding power information (such as low power or high power mode) and transmit it to the control module 103. The touch chip 122 clears the timer after detecting each valid touch sequence, and is ready to accept the next touch input. For example, the user presses 3 times within 1.5 seconds, and the touch chip 122 identifies that the number of touches meets the condition, and outputs the power information of the low power mode to the control module 103; when the user presses 3 times again within 1.5 seconds, the touch chip 122 identifies that the number of touches meets the condition, and outputs the power information of the high power mode to the control module 103.

[0054] As an example, as shown in Figure 6 The pin 1 of the touch chip U2 is connected to the control module 103, the pin 2 of the touch chip U2 is grounded, the pin 3 of the touch chip U2 is connected to the touch button, the pin 4 of the touch chip U2 is connected to the touch screen 121, the pin 5 of the touch chip U2 is connected to the power supply B+, and the touch chip U2 sends a touch signal TOCH WK to the control module 103 when it receives a touch action T10 or T11.

[0055] The technical effect of the embodiment is that the power mode of the electronic cigarette is quickly switched by accurately detecting the touch action of the user and combining the preset touch number and time conditions, and the user can switch between the low power mode and the high power mode through a simple touch operation, and the operation process is intuitive and efficient. The touch recognition technology makes the operation of the electronic cigarette more simple, without complex buttons or settings, greatly improving the convenience and intelligent level of the device.

[0056] As an embodiment, as shown in Figure 7 The power output module 104 includes a first MOS tube Q1, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first voltage stabilizing tube D1, and a fifth capacitor C5. One end of the fifth resistor R5, the source of the first MOS tube Q1, one end of the first voltage stabilizing tube D1, and one end of the sixth resistor R6 are connected together to receive an input power B+. The other end of the first voltage stabilizing tube D1 is grounded. The other end of the fifth resistor R5, the drain of the first MOS tube Q1, and one end of the third resistor R3 are connected together to form an output end of the power output module 104. The other end of the sixth resistor R6 is connected to the gate of the first MOS tube Q1 and one end of the fourth resistor R4. The other end of the fourth resistor R4 is a control end of the power output module 104. The other end of the third resistor R3 and one end of the fifth capacitor C5 are connected together to form a signal feedback end of the power output module 104. The other end of the fifth capacitor C5 is grounded.

[0057] For the power output module 104, the control module 103 adjusts the working state of the first MOS tube Q1 by outputting a PWM signal PWM_OUT1 to control the conduction and shutdown. The switching state of the first MOS tube Q1 determines the size of the output power, and outputs high power or low power. By receiving the feedback signal AD_RL, the control module 103 constantly monitors the power output module 104 and adjusts the output signal to ensure accurate control of the power.

[0058] The technical effect of the embodiment is that the switching state of the MOS tube is accurately adjusted, and the PWM control signal is combined to realize accurate regulation and control of the power output. Through the capacitor and resistor network of the feedback loop, the power output module 104 can stably output power and adjust in time to adapt to the changing input signal, thereby ensuring the stability and reliability of the electronic cigarette.

[0059] As an embodiment, as shown in Figure 8As shown, the driving module 105 includes a signal input module 131 and a driving chip 132. The power input end, data input end and clock signal input end of the signal input module 131 are respectively connected to the output end of the control module 103. The first control signal output end and the second control signal output end of the signal input module 131 are respectively connected to the two control ends of the driving chip 132. The driving signal output end of the driving chip 132 is connected to the control end of the double-color LED lamp module 106. The control module 103 outputs the first control signal and the second control signal to the driving chip 132 through the signal input module 131, so as to make the driving chip 132 output the row driving signal and the column driving signal to the double-color LED lamp module 106.

[0060] The signal input module 131 receives the power input signal, data input signal and clock signal from the control module 103, and ensures that these signals can be correctly transmitted to the driving chip 132. The power input end of the signal input module 131 receives the power signal provided by the control module 103, ensuring that the driving module 105 receives power to work. The data input end of the signal input module 131 receives the data input signal sent by the control module 103. These data usually include the brightness, color or mode information required by the LED lamp display. The clock signal input end of the signal input module 131 receives the clock signal sent by the control module 103. The clock signal is used to synchronize the transmission and update of data, ensuring that the LED lamp display is executed according to the correct timing. The signal input module 131 outputs the first control signal and the second control signal according to the received data and clock signal. These two signals are used to control the work of the driving chip 132. The driving chip 132 generates appropriate row driving signals and column driving signals according to the control signals (the first control signal and the second control signal) transmitted by the control module 103, and outputs them to the double-color LED lamp module 106, so as to control the display effect of the LED matrix and realize the lighting of specific LED lamps. The row driving signal and the column driving signal are sent to the control end of the double-color LED lamp module 106 to control the on-off state and display effect of each LED lamp.

[0061] As an example, as Figure 9As shown, the signal input module 131 includes a first resistor R1, a second resistor R2, a first capacitor C1, a second capacitor C2, a third capacitor C3, and a fourth capacitor C4. One end of the first resistor R1, one end of the second resistor R2, one end of the first capacitor C1, and one end of the second capacitor C2 are connected together as a power input terminal. The other end of the first capacitor C1 and the other end of the second capacitor C2 are connected together to ground. The other end of the first resistor R1 and one end of the third capacitor C3 are connected together as a data input terminal and a first control signal output terminal. The other end of the second resistor R2 and one end of the fourth capacitor C4 are connected together as a clock signal input terminal and a second control signal output terminal. The other end of the third capacitor C3 and the other end of the fourth capacitor C4 are connected together to ground. The driving chip U3 outputs eight row driving signals and eight column driving signals according to the first control signal and the second control signal, respectively.

[0062] The power input terminal receives a power signal PL_BAT+ through the first resistor R1, the second resistor R2, the first capacitor C1, and the second capacitor C2. This part of the circuit provides stable power for the driving chip U3 and uses capacitors to smooth power noise, ensuring the stability and filtering effect of the power supply and avoiding power interference affecting signal transmission. The connection between the first resistor R1 and the third capacitor C3 forms a data input terminal and a first control signal output terminal, and the data input terminal receives a data input signal LED_DAT from the control module 103. The third capacitor C3 filters the data input signal to avoid high-frequency noise in the electrical signal affecting accurate data transmission. The port transmits the received data to the driving chip U3 to further control the display of the LED matrix. The connection between the second resistor R2 and the fourth capacitor C4 forms a clock signal input terminal and a second control signal output terminal, and the clock signal input terminal receives a clock signal LED_CLK from the control module 103. The fourth capacitor C4 is used to filter and denoise the clock signal to ensure stable transmission of the clock signal. The main function of the driving chip U3 is to generate row driving signals and column driving signals according to the first control signal and the second control signal transmitted by the signal input module 131, and finally drive the LED matrix or LED lamp module to display the required pattern or color.

[0063] The technical effect of the embodiment is that the signal input module 131 effectively receives and transmits the power, data signal, and clock signal of the control module 103, ensuring that the driving chip 132 can accurately generate the required row driving signal and column driving signal, which controls the display effect of the dual-color LED lamp module 106, realizes accurate control of the LED matrix, and further displays different patterns, colors, or brightness.

[0064] As an implementation, the dual-color LED light module 106 includes a matrix arrangement of LED light groups, the cathodes of each row of LED light groups are commonly connected and receive a row drive signal, and the anodes of each column of LED light groups are commonly connected and receive a column drive signal.

[0065] The dual-color LED light module 106 is composed of a plurality of LEDs arranged in a matrix, and the LEDs in each row and each column receive a row drive signal and a column drive signal, respectively, through common connection. The function of the dual-color LED light module 106 is to accurately control the on-off and color of each LED according to the row drive signal and the column drive signal provided by the drive chip 132, so as to display different patterns, colors and dynamic effects in the matrix. The cathodes of each row of LED light groups are commonly connected, and the cathodes of all rows are connected to the row drive signal through common connection. The anodes of each column of LED light groups are commonly connected, and the anodes of all columns are connected to the column drive signal through common connection. The row drive signal output by the drive chip 132 is connected through the cathode of each row, and the row drive signal controls whether the LED in each row is on. In the display process, the row drive signal activates different rows in turn, so that only the LED in a certain row can be activated or controlled to display. The column drive signal is connected through the anode of each column, and the column drive signal controls whether the LED in each column is on. The column drive signal works with the row drive signal, and only when both the row drive signal and the column drive signal are valid, the LED at a specific position will be on. Each LED can select different colors, and the drive chip 132 controls different colors of different LEDs through the cooperation of the row drive signal and the column drive signal. The drive chip 132 controls the brightness and color change of each LED through appropriate signals, and presents the required display effect. The dual-color LED light module 106 can display different patterns or animation effects. By quickly switching the row and column drive signals, dynamic effects such as meteor shower, gradient breathing light, etc. can be achieved. The accurate cooperation of the row drive signal and the column drive signal realizes the control of each LED in the matrix, and achieves the effect of dynamic display. For example, if a pattern of a specific color needs to be displayed, the control module 103 generates specific row drive signals and column drive signals to control the relevant LED lights to be turned on.

[0066] As an implementation, the LED light group includes eight rows and eight columns of LED light groups, the first row, the second row, the sixth row, the seventh row and the eighth row of LED light groups display a first color, and the third row, the fourth row and the fifth row of LED light groups display a second color.

[0067] The LED light group is composed of eight rows and eight columns of LED lights, and the LED lights in each row and each column are controlled by row driving signals and column driving signals. There are 64 LED lights in each row and each column, or less than 64 LED lights, and the color of each LED light can be controlled by the combination of the row driving signals and the column driving signals. The LED lights in the first row, the second row, the sixth row, the seventh row and the eighth row will display the first color. For example, assuming that the first color is red, the LED lights in these rows will display red. The control module 103 causes the LED lights in these rows to light up and display red through the corresponding row driving signals and column driving signals. The LED lights in the third row, the fourth row and the fifth row will display the second color, for example, green. The control module 103 causes the LED lights in these rows to display green through the corresponding row driving signals and column driving signals. The cathodes of the LED lights in each row are connected in common, and the column driving signals control whether the LED lights in each column are lit through the anodes of the columns. The row driving signals of each row are activated in turn to control the state of all the LED lights in the row, and the column driving signals determine the specific on-off mode. In this configuration, different control signals are used to achieve a two-color display effect. The rows in which the first color is displayed and the rows in which the second color is displayed are precisely controlled through the cooperation of the row driving signals and the column driving signals. For example, the LED lights in the first row may display red, the LED lights in the second row also display red, the LED lights in the third row display green, and so on. Due to the flexibility of the matrix structure, more colors or effects can be added by adjusting the control signals. For example, different rows can be made to display other colors as needed, or dynamic effects such as gradient, flicker, flow, etc. can be achieved.

[0068] As an example, as shown in FIG. 1, the fourth row, the sixth column, the fourth row, the seventh column, the seventh row, the sixth column, the seventh row, the seventh column and the seventh row, the eighth column positions of the eight-row and eight-column LED light group do not have LED light groups, and the remaining positions all have LED light groups. Figure 10

[0069] In actual design, some positions do not have LED lights, and the fourth row, the sixth column, the fourth row, the seventh column, the seventh row, the sixth column, the seventh row, the seventh column and the seventh row, the eighth column positions do not have LED lights. In these specific positions, no light will be lit. In addition to the above-mentioned five positions, the remaining positions in the matrix will have LED lights. That is, in addition to these five specific positions, all other positions (such as the first row, the first column, the second row, the third column, etc.) will be installed and display LED lights. As shown in FIG. 1, the first row, the first column, the second row, the third column, the third row, the second column, the fourth row, the first column, the fifth row, the first column, the sixth row, the second column, the seventh row, the second column, the eighth row, the second column, the eighth row, the third column, the eighth row, the fourth column, the eighth row, the fifth column, the eighth row, the sixth column, the eighth row, the seventh column, the eighth row, the eighth column positions of the eight-row and eight-column LED light group are all installed and display LED lights.
