[0051] In order to further understand the technical solutions of some embodiments of the present application, the technical solutions of the electronic cigarette and its mixed taste adjusting 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. The embodiments 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 some of the embodiments of the present application, not all.

[0052] In some embodiments, as shown in Figure 1 A mixed taste adjusting circuit of an electronic cigarette is provided, and the mixed taste adjusting circuit comprises:

[0053] The air pressure detection module 101 is configured to generate an electrical signal when detecting that the air pressure reaches a triggering condition, and output a detection signal after amplifying the electrical signal;

[0054] The parameter input module 102 is configured to obtain and output a parameter value of each taste in at least two tastes to be mixed;

[0055] The control module 103 and the at least two power output modules 104, the first signal input end of the control module 103 is connected to the output end of the air pressure detection module 101, the second signal input end of the control module 103 is connected to the output end of the parameter input module 102, and the output end of the control module 103 is connected to the control end of each power output module 104 respectively, and the control module 103 is configured to control the power output module 104 corresponding to each taste to work simultaneously according to the parameter value of each taste when receiving the detection signal.

[0056] The air pressure detection module 101 monitors the air pressure to reach the trigger condition and outputs a detection signal. The air pressure detection module 101 detects the air pressure change in real time through a sensor (such as a microphone). When the air pressure changes to reach the trigger condition, the air pressure detection module 101 converts the air pressure signal into an electric signal and processes the signal into a detection signal, which is output to the input end of the control module 103. The parameter input module 102 inputs and obtains the parameter value of each mixed taste. The parameter input module 102 is composed of a user interface or a sensor, which is used to set or obtain the adjustment parameters (such as the proportion) of each taste. These parameter values are transmitted to the control module 103 for use in adjusting the mixed taste. The control module 103 controls the working state of the power output module 104 according to the detection signal and the parameter value of each taste. The control module 103 receives the detection signal from the air pressure detection module 101 and starts to process the task related to the taste mixing. The control module 103 also receives the taste parameter value from the parameter input module 102. According to the detection signal and the taste parameter value, the control module 103 calculates which power output modules 104 should be activated and how to adjust the output power of each power output module 104. The control module 103 sends instructions to the control end of each power output module 104, instructing it to start working or stop working. The control module 103 controls at least two power output modules 104 to work simultaneously. Taking the first power output module and the second power output module as an example, the first power output module controls the power output of the first taste. The first power output module adjusts the output power of the corresponding taste according to the instruction of the control module 103. When the control module 103 issues an instruction, the first power output module starts to output power to adjust the concentration or intensity of the taste. If the instruction of the control module 103 is to close the module, the first power output module stops working. The second power output module controls the power output of the second taste. The working principle of the second power output module is the same as that of the first power output module. The control module 103 adjusts the power output of the module through a signal instruction to change the concentration or intensity of the second taste. If the instruction of the control module 103 is to close the module, the second power output module 142 stops working.

[0057] The technical effect of the embodiment is that through the cooperative work of the air pressure detection module and the control module, the precise control of multiple taste adjustment modules is realized. The air pressure detection module monitors the air pressure change in real time and transmits the signal to the control module. The parameter input module provides the taste proportion parameter set by the user. The control module accurately controls the working state of multiple power output modules and adjusts the output power of each taste according to the received air pressure signal and taste parameter value, so as to accurately adjust the concentration or intensity of different tastes and output multiple mixed tastes. The technical solution not only can respond to the air pressure change in real time, but also can adjust the mixing effect of different tastes to provide more flexible and personalized taste experience.

[0058] As an embodiment of the air pressure detection module 101, as shown in Figure 2 The air pressure detection module 101 comprises:

[0059] The microphone module 111 is configured to generate and output an electrical signal when detecting air pressure change.

[0060] The conversion module 112 is connected to the input end of the microphone module 111 and the output end of the air pressure detection module 101, and is configured to output a detection signal when the electrical signal meets a trigger condition.

[0061] The microphone module 111 is configured to detect air pressure change and convert the air pressure change into an electrical signal. The microphone module 111 usually consists of one or two air pressure sensors and can sense air pressure change. When the air pressure changes, the microphone module 111 converts the change into an electrical signal, which reflects the degree of air pressure change. The output electrical signal is the input signal of the air pressure detection module 101 and will be sent to the conversion module 112 for detection. The conversion module 112 receives the electrical signal output by the microphone module 111 and processes the signal according to the set trigger condition. If the received electrical signal meets the preset air pressure change condition (e.g., the air pressure drops to a certain threshold), the conversion module 112 outputs a detection signal.

[0062] As an example, as shown in Figure 3 and Figure 4 The microphone module 111 comprises 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, which can sense air pressure change. When the air pressure changes, the air pressure sensor converts the change into an electrical signal. The chip U1 detects the electrical signal and outputs a detection signal SMK_WK to the control module 103 when the electrical signal meets the preset air pressure change condition, as shown in Figure 3 As an example of the control module 103, the control module 103 is a chip U0, and the pin 1 of the chip U0 receives the detection signal SMK_WK.

[0063] As an embodiment, the parameter input module 102 comprises:

[0064] The touch chip is connected to the output end of the control module 103 and is configured to obtain and output the percentage of each flavor in the at least two flavors to be mixed according to user action.

[0065] The touch chip can sense the user's touch action, usually by detecting the contact of a finger or other conductive object on the touch surface. The touch chip usually contains a touch sensing circuit for determining the position and pressure of the finger and identifying the touch type (such as single-point touch, multi-point touch, sliding, etc.). The user adjusts the taste ratio through the touch interface provided by the touch chip. Through the sliding, clicking, etc. operations of the finger on the touch screen or touch panel, the user can control the percentage of each taste in the mixed taste. The touch chip can accurately convert this input into digital signals, usually two or more taste parameters, to determine the percentage of each taste. The touch chip will output corresponding digital signals according to the touch data input by the user, and these signals will be transmitted to the control module 103. The output signal is usually digitized data representing the adjustment ratio of each taste, which is provided for the control module 103 for further processing and decision-making. The output end of the touch chip is connected to the control module 103, and the control module 103 adjusts the power output module according to the received input signal to realize the mixing of different tastes. The working process of the touch chip is as follows: the user specifies the ratio of each taste by touching a specific area (such as two sliding bars or adjustment buttons) on the touch panel or screen. The touch chip detects the user's finger touch and sliding action and obtains the user's input data in real time. The touch chip calculates the adjustment value of each taste according to the touch event, usually by sensing the user's touch action through capacitance change or resistance change and converting it into a digital signal. The touch chip outputs these data as signals, usually through a serial interface (such as I2C or SPI) to transmit data to the control module 103. After receiving these digital signals, the control module 103 parses the percentage value of each taste and adjusts the operation of the power output module according to this information, thereby realizing the mixing ratio of different tastes.

[0066] The technical effect of the embodiment is that the user can intuitively adjust the ratio of different tastes through the touch chip, providing accurate input control. The touch chip can quickly respond to the user's touch operation and convert the input into a digital signal, ensuring that the control system can timely adjust the taste ratio.

[0067] As an embodiment, as Figure 5As shown, the power output modules include a first power output module 141, a second power output module 142, and a third power output module 143. The first signal output end of the control module 103 is connected to the control end of the first power output module 141. The signal feedback end of the first power output module 141 is connected to the third signal input end of the control module 103. The second signal output end of the control module 103 is connected to the control end of the second power output module 142. The signal feedback end of the second power output module 142 is connected to the fourth signal input end of the control module 103. The third signal output end of the control module 103 is connected to the control end of the third power output module 143. The signal feedback end of the third power output module 143 is connected to the fifth signal input end of the control module 103. The control module 103 is configured to output a corresponding PWM control signal to each power output module corresponding to each taste according to the percentage of each taste when receiving a detection signal.

[0068] The control module 103 receives the detection signal from the air pressure detection module 101, determines the air pressure change (such as inhaling action), obtains the percentage data of each flavor from the parameter input module 102, sets the power output ratio of each flavor, and obtains the corresponding PWM control signal when receiving the detection signal. The PWM control signal is sent to the first power output module 141, the second power output module 142, and the third power output module 143 through the first signal output end, the second signal output end, and the third signal output end, respectively. The control module 103 also obtains signal feedback from each power output module, monitors and adjusts the power output in real time through the signal feedback end, and ensures that each power output module works as required. The first power output module 141 adjusts the output power according to the PWM control signal sent by the control module 103, thereby controlling the atomization effect of the first flavor of the electronic cigarette. The first power output module 141 receives the PWM control signal from the control module 103, adjusts the output power to ensure that the set flavor ratio is reached, and feeds back the power output signal to the control module 103 for real-time monitoring of the power output state by the control module 103. The second power output module 142 receives the second PWM control signal from the control module 103, adjusts the power output of the second flavor, controls the power output of the second flavor through the duty cycle of the PWM signal, feeds back the power output signal to the control module 103, and makes adjustments by the control module 103. The third power output module 143 receives the third PWM control signal from the control module 103, adjusts the power output of the third flavor, changes the power of the third flavor through the duty cycle of the control signal, feeds back the power output signal to the control module 103, and ensures the continuous and stable operation of the system. The signal feedback end of each power output module is used to feed back the working state and actual output power of the power output module to the control module 103. The control module 103 adjusts the PWM control signal according to the feedback signal to achieve precise power control. The signals (such as current, voltage, etc.) output by the power output module are fed back to the control module 103. The control module 103 obtains real-time information of the output power through the signal feedback end, ensures that the output power of each power output module meets the expected flavor ratio, and makes fine adjustments to the PWM signal according to the feedback information to maintain the accuracy and stability of the system.

[0072] For the first power output module 141, the control module 103 adjusts the working state of the first MOS tube Q1 and the second MOS tube Q2 by outputting the PWM signal V1_PWM to control the on and off, and the switching state of the first MOS tube Q1 and the second MOS tube Q2 determines the size of the output power.

For the second power output module 142, the control module 103 adjusts the working state of the third MOS tube Q3 and the fourth MOS tube Q4 by outputting the PWM signal V2_PWM to control the on and off, and the switching state of the third MOS tube Q3 and the fourth MOS tube Q4 determines the size of the output power. By receiving the feedback signal AD2_RL, the control module 103 constantly monitors the second power output module 142 and adjusts the output signal to ensure accurate control of the power. For the third power output module 143, the control module 103 adjusts the working state of the fifth MOS tube Q5 and the sixth MOS tube Q6 by outputting the PWM signal V3_PWM to control the on and off, and the switching state of the fifth MOS tube Q5 and the sixth MOS tube Q6 determines the size of the output power. By receiving the feedback signal AD3_RL, the control module 103 constantly monitors the third power output module 143 and adjusts the output signal to ensure accurate control of the power.

[0074] As an embodiment, as shown in Figure 9 The mixed taste adjusting circuit further includes a display module 105 connected with the control module 103, for displaying the parameter values of each power module in operation.

[0075] The display module 105 is mainly used for real-time display of the parameter values of each power output module in operation, such as power, taste ratio and other related information. The display module 105 is connected with the control module 103, can receive parameter data from the control module 103, and displays it to the user through appropriate display mode, ensuring that the user can clearly understand the current system running state. The display module 105 is connected with the control module 103 through a communication interface, and the control module 103 is responsible for receiving and processing the working parameters (such as power, taste ratio, etc.) from each power output module. The control module 103 generates corresponding power parameter signals (such as different power values, taste ratios, etc.) according to the state of the power output module and the input user parameters. The display module 105 displays the power parameter values to the user in real time according to the received data, using a screen or display panel (such as LED, LCD or OLED, etc.). For example, when the user adjusts the power output, the display module will update and display the current power value and taste ratio in real time. The display module can feedback the system working state in real time, helping the user to intuitively understand the device running condition, adjust the output or taste ratio to achieve the desired atomization effect. The user inputs new parameters to the control module 103 through the touch screen, button or other interactive mode, and the display module will update the display content according to the data processed by the control module 103, ensuring that the user can check and adjust the working state of the device at any time.

[0076] As an example, as shown in Figure 10As shown, the control module 103 sends a signal LCD RS to pin 1 of the display screen interface chip U2, a signal LCD_RST to pin 2 of the display screen interface chip U2, a signal LCD_MOSI to pin 3 of the display screen interface chip U2, a signal LCD_CLK to pin 4 of the display screen interface chip U2, a signal LCD_CS to pin 5 of the display screen interface chip U2, pin 6 of the display screen interface chip U2 is grounded, pin 7 of the display screen interface chip U2 is connected to one end of the capacitor C4, one end of the capacitor C5 and a voltage signal 3.0V S, the other end of the capacitor C4 is connected to the other end of the capacitor C5, pin 8 and pin 10 of the display screen interface chip U2, pin 9 of the display screen interface chip U2 is connected to one end of the resistor R30, and the other end of the resistor R30 is connected to a voltage signal 3.0V.

[0077] The control module 103 sends signals with the following functions:

[0078] LCD RS (pin 1): This signal is used to select the command or data mode. If the signal is high, the data mode is selected; if the signal is low, the command mode is selected.

[0079] LCD_RST (pin 2): This signal is used to reset the display screen interface chip, ensuring that the chip is initialized each time it is turned on.

[0080] LCD_MOSI (pin 3): This signal is used to transmit data. The control module 103 sends display data or commands to the display screen through this pin.

[0081] LCD_CLK (pin 4): This signal is a clock signal used to synchronize the transmitted data and drive the timing of the display screen interface chip.

[0082] LCD_CS (pin 5): This signal is used to select the display screen interface chip for communication. When it is low, the chip is selected and communication begins.

[0083] Pin 7 of the display screen interface chip U2 is connected to one end of the capacitor C4, one end of the capacitor C5 and a voltage signal 3.0V. Capacitors C4 and C5 may function to stabilize voltage, filter or denoise, ensuring stable operation of the display screen. The voltage signal 3.0V is the voltage required for the display screen to operate, providing the necessary operating voltage.

[0084] Pin 9 of the display screen interface chip U2 is connected to one end of the resistor R30, and the other end of the resistor R30 is connected to a voltage signal 3.0V. Resistor R30 is used for voltage division, current limiting or controlling certain characteristics of the display screen (such as brightness or contrast).

[0085] The control module 103 controls the display content of the display screen through these signals. When the control module 103 sends new data or commands, the display screen interface chip U2 will control the pixel array of the display screen according to the received signals and voltage settings, changing the display content.

[0086] The technical effect of the embodiment is that the display module provides an intuitive interface to display the working parameters of the power module, improving the user experience. By providing real-time feedback of the parameter values, users can more accurately control the flavor mixing and power output, ensuring stable performance of the electronic cigarette and allowing for individual adjustments. This design enhances the interactivity and ease of use of the system, further optimizing the control and operation process of the device.

[0087] As an embodiment, as shown in Figure 11 The mixed flavor adjustment circuit further includes:

[0088] The charging module 106 is connected to the control module 103 and is used to send a wake-up signal to the control module 103 when an external power source is connected, and to charge the battery module according to the charging control signal of the control module 103.

[0089] The charging module 106 includes a charging chip and a charging interface, and the charging chip is connected to the charging interface and the control module 103. When the charging chip is connected to the external power source through the charging interface, it sends a wake-up signal to the control module 103 and charges the battery according to the charging control signal of the control module 103.

[0090] The charging module 106 sends a wake-up signal to the control module 103 when the device is connected to an external power source, and controls the external power source to charge the battery according to the charging control signal of the control module 103. Its function is to ensure the smoothness of the battery charging process and to manage the battery charging state through cooperation with the control module 103.

[0091] The charging chip is responsible for connecting with the external power supply and managing the charging of the battery module. After receiving the charging control signal from the control module 103, the charging chip adjusts the charging process to ensure that the battery module is charged under the correct voltage and current conditions. Another main function of the charging chip is to send a wake-up signal to the control module 103 when the external power supply is connected, starting the charging process. When the external power supply is connected through the charging interface, the charging chip detects the power input and sends a wake-up signal to the control module 103 through the signal line. After receiving the wake-up signal, the control module 103 starts working and sends a charging control signal to the charging chip. According to this signal, the charging chip supplies power to the battery module and monitors the battery voltage and current in real time to ensure the safety and efficiency of the charging process. The charging interface is used to connect with the external power supply to provide power input. The charging chip manages the charging process of the battery module to ensure that the battery is charged within a safe range and prevent overcharging or over-discharging. When the battery is fully charged, the charging chip stops charging and notifies the control module 103, and the system may enter standby state or turn off the charging.

[0092] As an example, as shown in Figure 12 and Figure 13 , the charging module 106 includes a charging chip U3 and a charging interface U4. The pin IN of the charging chip U3 is connected to one end of the resistor R31, one end of the resistor R32, and one end of the capacitor C6. The other end of the resistor R31 is connected to the voltage VIN. The other end of the resistor R32 is connected to one end of the capacitor C7. The pin CHG of the chip U3 outputs a wake-up signal USB_WK to the control module 103. The pin BAT of the chip U3, one end of the capacitor C8, and one end of the capacitor C9 are connected together and connected to the positive terminal of the battery module 107. The pin INSET of the chip U3 is connected to one end of the resistor R33. The other end of the resistor R33 and one end of the resistor R34 are connected together and receive the CHG_EN signal output by the control module 103. The other end of the capacitor C7, the other end of the capacitor C6, the pin GND of the chip U3, one end of the resistor R34, one end of the capacitor C8, and one end of the capacitor C9 are connected together and connected to the negative terminal of the battery module 107. As shown in Figure 12 , when the charging interface U4 is connected to the external power supply, the pin VBUS outputs the voltage VIN, the pin CC1 outputs the signal SWDIO to the control module 103, and the pin CC2 outputs the signal SWCLK to the control module 103.

[0093] The technical effect of the embodiment is that the cooperation of the charging chip and the control module ensures the protection of the battery during the charging process, avoiding overcharging or battery damage, and through the dynamic management of the wake-up signal and the charging control signal, the overall performance of the system and the service life of the battery are improved.

[0094] As an embodiment, as shown in Figure 14 , the mixed taste adjusting circuit further comprises:

[0095] The voltage acquisition module 108 is connected to the battery module 107 and the control module 103 respectively. When the control module 103 receives the wake-up signal, it sends a charging control signal to the charging chip through the voltage acquisition module 108 when the battery voltage meets the preset condition.

[0096] The voltage acquisition module 108 is used to detect the battery voltage and transmit its data to the control module 103, so that the control module 103 can determine whether the battery voltage meets the charging condition after receiving the wake-up signal, and send a charging control signal to the charging chip accordingly. The voltage acquisition module 108 ensures that the system charges within an appropriate voltage range, thereby improving the safety and efficiency of battery charging. When the charging interface detects the connection of an external power source, the charging chip sends a wake-up signal to the control module 103, prompting the system to enter the charging management mode. The voltage acquisition module 108 acquires the current battery voltage from the battery module 107 and converts the data into a suitable signal for transmission to the control module 103. After receiving the battery voltage data from the voltage acquisition module, the control module 103 compares it with the preset threshold value: if the battery voltage is below the charging threshold, the control module 103 sends a charging control signal to the charging chip to start the charging process. If the battery voltage is above the safety threshold (e.g., near full charge), the control module 103 will not send a charging control signal to prevent overcharging. After the control module 103 sends the charging control signal, the charging chip adjusts the charging current and voltage according to the control signal and starts charging the battery. The voltage acquisition module 108 continues to monitor the battery voltage and feeds back to the control module 103 in real time, so that the control module 103 can terminate the charging when the battery is fully charged. During the charging process, the voltage acquisition module 108 continuously monitors the battery voltage until it detects that the voltage reaches the full charge state (e.g., 4.2V). Based on the voltage data, the control module 103 sends a stop charging signal to the charging chip to turn off the charging circuit, preventing overcharging of the battery and improving the battery's lifespan and safety.

[0097] As an example, as shown in Figure 15 The voltage acquisition module 108 includes a transistor Q7, a transistor Q8, a resistor R41, a resistor R42, and a capacitor C11. The emitter of the transistor Q8 is connected to the output of the battery module 107, the base of the transistor Q8 is connected to the collector of the transistor Q7, the base of the transistor Q7 is connected to the signal output of the control module 103, the emitter of the transistor Q7 is grounded, the collector of the transistor Q8 is connected to one end of the resistor R41, the other end of the resistor R41, one end of the resistor R42, and one end of the capacitor C11 are connected together and connected to the signal input of the control module 103, and the other end of the resistor R42 and the other end of the capacitor C11 are connected together and grounded.

[0098] The control module 103 outputs a control signal BAT2_AD_EN to the triode Q7, so that the triode Q7 is turned on, the collector and the emitter of the triode Q7 are connected, and then the base of the triode Q8 is connected to the ground, so that the triode Q8 is turned on, the battery module 107 outputs a current through the triode Q8, and a feedback signal BAT_AD is output through the voltage division of the resistor R41 and the resistor R42 to the control module 103, and the control module 103 controls the charging module 106 to supply power to the battery module according to the state of the battery module.
