[0042] The circuit system of the present invention solves the problem of limited personalization of existing electronic cigarette products. It realizes multi-theme switching through the FLASH module 7 and the screen display module 5, and assists in realizing convenient and fast theme switching through the voice processing and playback module 6. It can also realize functions such as power adjustment and intelligent reminders to adapt to the power triggering requirements of different types of e-liquids, achieve the best taste, improve product experience, enhance product practicality, and increase user stickiness.

[0043] The present invention is also provided with a tpyeC upgrade function. Through the tpyeC module 11, the resources of the main control module 1 and the flash module 7 can be upgraded. After the user buys the product, he can change different UI themes according to his preferences to achieve personalized customization. For example, the present invention is connected to the upgrade host computer through the tpyeC module 11, and the software determines whether the upgrade content is the main control chip program or the FLASH program, and then starts the upgrade transmission.

[0044] As a supplement, Figure 2-6 Figure 1 shows a circuit diagram of the main control chip U6 in the main control module. The chip model is PY32F030 and is packaged in a QFN32 package. The VCC portion of the main control chip U6 requires a 3.3V power supply (pin 1), which is provided by the LN1132 voltage regulator chip in the power management module 4. Specifically, the main control chip U6 uses an SPI communication interface to connect to the FLASH chip in the FLASH module 7. Pins 9-14 (CS, HOLDE, SCLK, SO, SI, WP) are used to read program code stored in the Flash chip to execute corresponding operations. User data or configuration information is also written to the Flash chip for storage, meeting the user's personalized needs. The main control chip U6 is connected to the LCD screen of the display module 5 via six signal lines, and a control signal is sent through the 3V3_EN enable pin (pin 3), which accordingly turns on the circuit of the LCD screen, allowing the circuit to be turned on as needed to reduce power consumption. Through the coordinated cooperation of the six signal lines, it is ensured that the main control chip U6 can correctly send commands and data to the LCD and control the LCD display to achieve personalized theme display, among which:

[0045] LCD_CS (pin 6): Chip select signal interface, which is used to select or activate the LCD for data transmission. When LCD_CS is activated (usually low), the LCD will respond to the data or commands sent by the main control chip U6.

[0046] LCD_SCK (pin 2): Serial clock signal interface, used to synchronize data transmission between LCD and main control chip U6. When LCD receives the clock signal, it will read or write data according to the specified timing.

[0047] LCD_SDA (pin 30): Serial data interface, which is the main channel for the main control chip U6 to send data or commands to the LCD. Data is transmitted through the LCD_SDA interface under the synchronization of the LCD_SCK clock signal.

[0048] LCD_EN (Pin 25): Enable signal interface used to control LCD data transmission operation. When LCD_EN is high, the LCD display reads the data on LCD_SDA and synchronizes according to the clock signal of LCD_SCK.

[0049] The utility model has a voice playback function, such as Figure 8 As shown, the main control chip U6 is connected to TG1 (pin 21), which acts as the switch button 10 of the AUDIO part. When the main control chip U6 needs to play a voice prompt, the AUDIO part is triggered through this pin to start working and complete the voice prompt.

[0050] The user can simply and conveniently operate KEY1 (pin 28), and the main control chip U6 can receive and process the signal sent by KEY in real time, execute the user's corresponding control instructions, and realize the power on and off, mode switching and other operations of the atomization system.

[0051] The main control chip U6 utilizes the MIC (pin 32), PWM2 (pin 26), ADC2 (pin 7), and RL2_CHK2 (pin 27) to establish a basic atomization control system. The MIC senses the user's inhalation in real time, specifically the sensor signal from the microphone in sensor module 3. This signal is then transmitted to the main control chip U6, ensuring a timely and accurate response. PWM2, on the other hand, controls the heating element's timing and temperature by adjusting the PWM signal's duty cycle. This involves adjusting the on-time of the MOSFET in circuit control module 8, thereby affecting vapor volume and flavor. The ADC pin then transmits temperature, duration, and other signals back to the main control chip U6 for more precise control. The RL2_CHK2 pin is used to detect the resistance of the heating element before the system atomizes, identifying potential issues (such as damage or aging) and preventing adverse events during the atomization process. The main control chip U6 also provides two serial debugging interfaces: SWCLK (pin 24) and SWDIO (pin 23).

[0052] The main control chip U6 forms the power management part with the power management module 4 through the pins AD_NTC, CHR_OK, CHR_ON, AD_BAT, LOW, and TDC. These pins each have different functions and work together to ensure that the power system of this system can work safely and efficiently. Among them, the operation of each pin is as follows:

[0053] AD_NTC (Pin 8): The NTC thermistor in sensor module 3 is connected to the main control chip U6 via the AD_NTC pin, which is used to monitor the temperature of the e-cigarette battery 9 or the interior of the e-cigarette in real time. By reading the analog signal from the AD_NTC pin, the main control chip U6 can determine whether the e-cigarette is within a safe operating temperature range. If the temperature is too high, the main control chip U6 can take appropriate measures, such as reducing the output power of the e-cigarette or shutting down the e-cigarette, to prevent the e-cigarette or battery 9 from overheating and causing danger.

[0054] CHR_OK (pin 22) and CHR_ON (pin 20): These two pins are related to the e-cigarette's charging function. When the e-cigarette is connected to a charger and begins charging, the CHR_ON pin is activated, notifying the main control chip U6 that the e-cigarette is currently charging. When charging is complete, the CHR_OK pin is activated, indicating that the charging process has been successfully completed. The main control chip U6 can control the e-cigarette's charging process based on the status of these two pins and perform corresponding operations after charging is complete, such as disconnecting the charging circuit or displaying a prompt indicating that charging is complete.

[0055] AD_BAT (pin 15): used to monitor the voltage of the electronic cigarette battery 9. The main control chip U6 can read the analog signal of the AD_BAT pin to know the remaining power of the battery 9 in real time. According to the power level of the battery 9, the main control chip U6 can adjust the working state of the electronic cigarette, such as reducing the output power when the power is low or reminding the user to charge in time.

[0056] LOW (Pin 17): When the battery 9 of the electronic cigarette is low on power, the LOW pin will be activated. By detecting the status of this pin, the main control chip U6 can determine whether the battery 9 is too low and take appropriate measures, such as shutting down the electronic cigarette or displaying a low battery prompt to prevent the electronic cigarette from suddenly stopping due to depletion of power.

[0057] TDC (pin 18): used for charging high voltage detection, and also detects whether the Type-C plug is inserted into the Type-C module 11, and detects whether high voltage is generated to protect subsequent circuits.

[0058] Through the coordinated work of these pins and the main control chip U6, the power management part of this system can realize functions such as temperature monitoring, charging control, and battery 9 power monitoring, ensuring that the electronic cigarette can work safely and stably.

[0059] In another embodiment, the main control chip U6 may be a Bluetooth chip, such as the nRF52832 chip, which is a low-power Bluetooth system-on-chip.

[0060] exist Figure 3 In the system, the FLASH module 7 uses the P25D440SH model package information SOP8 as the FLASH chip U3 of this system, with a storage capacity of 4M*1bit, which can store a variety of theme files, including images, color schemes and user interface layouts, etc., to meet the user's needs to change the e-cigarette theme in real time according to personal preferences. Figure 3 This is a block diagram of the FLASH chip U3. The 3V3A pins connect the LCD, AUDIO, and SPK components. This allows the main control chip U6 to read data or commands from the LCD, forming a closed-loop circuit that triggers the FLASH chip to retrieve and display the FLASH chip's information while also playing the corresponding audio. The integration of the FLASH chip into the design not only reduces the storage burden on the main control chip U6 but also increases the speed of information reading, making the e-cigarette display smoother and faster. The pins of the FLASH chip U3 are as follows:

[0061] flash_cs: Chip select signal, used to select or activate the flash memory chip. When the flash_cs signal is activated, it indicates that the flash memory is currently communicating with the main control chip.

[0062] flash_so: Serial output signal, used to read data from the flash memory. The flash memory transmits data serially to the main control chip through this pin.

[0063] flash_wp: Write protection signal used to prevent accidental write operations to the flash memory. When the flash_wp signal is activated, write operations to the flash memory are usually prohibited to prevent data loss or corruption.

[0064] flash_holde: Hold signal, used to suspend data transmission between the flash memory and the main control chip. When the flash_holde signal is activated, the flash memory will suspend its operation until the signal is released.

[0065] flash_sclk: Serial clock signal used to synchronize data transfer between the flash memory and the main control chip. The flash_sclk signal defines the rate and timing of data transfer.

[0066] flash_si: Serial input signal, used to write data to the flash memory. The main control chip transmits data serially to the flash memory through this pin.

[0067] These pins work together to ensure that the electronic cigarette's main control chip can correctly communicate with the flash memory to enable data reading, writing and storage.

[0068] exist Figure 4 The AK2301 MOS transistor Q1 used in the present invention plays a crucial role in the communication between the LCD screen of the display module 5 and the main control chip U6. When the main control chip U6 transmits data or commands to the LCD screen, it sends control signals through the 3V3_EN enable pin. One of the key signals is the E signal. When the main control chip U6 needs to send data to the LCD screen, it sets the E signal to a high level. Once the E signal becomes high, the AK2301 MOS transistor Q1 will receive this signal and turn on the circuit accordingly. This switching characteristic of the MOS transistor Q1 enables the circuit to conduct on demand, providing the required power or signal to the LCD screen.

[0069] In this state, the LCD_CS signal is activated, LCD_RS determines whether the received data is a command, and begins to process the information received from the SCK (serial clock) and SDA (serial data) interfaces. SCK and SDA are interfaces commonly used for serial communication, which are responsible for the transmission of clock signals and data respectively. Through these two interfaces, the main control chip U6 can send data and control commands to the LCD screen in an orderly manner. The LCD screen can read data from the SDA interface according to the rhythm of the clock signal, and work with the FLASH chip to complete the update of the display content or respond to the corresponding operation. LCD_RST represents the reset signal of the screen, which is used to reset the LCD module to the initial state to ensure that it can work correctly during startup or reconfiguration.

[0070] exist Figure 5-6 In the embodiment, the power management module 4 includes two parts, namely a charging unit and a power supply unit.

[0071] The charging unit uses charging chip U1 for charging management, which manages the charging process, including charging current, charging voltage, and charging indication. Charging chip U1 can be model AK4056H, which is a 1A single-cell lithium-ion battery linear charger with a high input voltage of up to 28V and a power supply OVP function. It adopts a constant current / constant voltage charging mode and charges via a Type-C interface.

[0072] The power supply unit includes a voltage regulator, a voltage divider, and a negative temperature coefficient thermistor. The voltage regulator (LDO) provides a standard 3.3V voltage to the system. The 3.3V voltage regulation is implemented using the LN1132 chip U2, a dedicated voltage regulator with a 5V input and a 3.3V output, powering the microphone of sensor module 3 and the LCD screen of display module 5. In the voltage divider (BAT_CHR), the power supply reduces the higher voltage through resistor R10 to a level that can be safely received by the main control chip U6. The battery 9 voltage status is then transmitted to the main control chip U6 via AD_BAT, thereby protecting the main control chip U6 while allowing the main control chip U6 to control and display the battery 9 voltage status. To save power during this voltage divider process, a LOW pin is also provided, which is reversely controlled by the main control chip U6. When the main control chip U6 pin needs to detect the battery 9 voltage status, the battery 9 voltage is reduced to the voltage required by AD_BAT to form a closed-loop circuit. Otherwise, the closed loop cannot be formed, and the detection state is disabled. The negative temperature coefficient thermistor (NTC_CHR) is used to detect temperature during the charging process. When the temperature of the battery 9 or the charging circuit is too high, the control system can sense the change by reading the resistance value of the NTC thermistor and take measures such as reducing the charging current or stopping charging to prevent overheating.

[0073] In the power management module 4, a MIC is added to connect to the PROG interface, which can be used for atomization during charging. The charging current can be turned off by pulling the level high through PROG.

[0074] exist Figure 7 In the circuit control module 8, the JXP1216DRG MOS transistor Q2 supports a maximum current of 16A and a maximum voltage of 12V. When the user uses the e-cigarette, the main control chip U6 receives the instruction and outputs a corresponding pulse signal through the PWM pin to control the conduction of the MOS transistor Q2. When the MOS transistor Q2 is turned on, the electrical energy of the battery 9 flows through it to the heating wire, causing the heating wire to generate heat. This heat in turn heats the e-cigarette oil, causing it to evaporate rapidly and produce an atomization effect. By precisely controlling the duty cycle and frequency of the PWM signal, the main control chip U6 can achieve precise adjustment of the heating power of the heating wire to achieve the purpose of providing different concentrations and flavors of smoke according to the user's smoking habits and needs. In addition, the MOS transistor Q2 also feeds back signals such as temperature and duration to the main control chip U6 via the ADC pin, allowing for more precise control and providing users with a personalized smoking experience.

[0075] exist Figure 7 In the schematic diagram, the RL2_CHR2 IO port is added to connect to the main control chip U6 to monitor the resistance of the heating wire before smoking. During the monitoring process, the main control chip U6 sends a signal to transistor Q5 through the RL2_CHR2 IO port, turning it on and allowing current to flow. This generates a voltage drop in the heating wire, which is fed back to the main control chip U6. Based on this information, the main chip U6 determines whether the heating wire is normal. If it exceeds the safe range, it takes appropriate measures to ensure the normal operation of the system.

[0076] Additionally, the Type-c module 11 is a Type-c socket that can be connected to a Type-c plug to upgrade the main control chip and the FLASH chip, as well as to supply power to the power management module.

[0077] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in this disclosure.
