[Technical field]

[0001] The present invention relates to the technical field of embedded devices, and in particular to an electronic atomization oral care system with dynamic interactive function. [Background technology]

[0002] Atomizers usually consist of batteries, heating elements, and containers for storing atomized drugs. The heating elements are triggered by inhalation to heat the atomized drugs into steam for users to inhale. Compared with traditional cigarettes, atomizers are more diverse and reusable, providing users with a more personalized experience and meeting the diverse needs of consumers. As a new tobacco product, atomizers have undergone rapid development and changes in both technology and the market. At present, the market is showing an explosive growth trend worldwide. According to the research and statistics of the QYResearch research team, the global atomizer market sales reached 173.3 billion yuan in 2023, and it is expected to reach 305.13 billion yuan in 2030, with a compound annual growth rate (CAGR) of 8.7% (2024-2030). The future development market of atomizers is considerable, and the audience group is gradually increasing.

[0003] According to existing research results, the age of the audience of atomizers is mainly concentrated between 18 and 35 years old, accounting for 70%. Among them, users aged 18 to 25 account for the highest proportion, reaching 30%. The people who use atomizers are mainly young people, which means that in addition to meeting basic functional requirements, atomizers will also gradually increase personalized needs. As for the common atomizer products on the market, there are still the following problems:

[0004] 1. The interaction methods are not rich enough: Most of the interaction methods of existing products are through suction microphones and buttons to interact with users, and the interaction methods are not rich enough.

[0005] 2. Lack of fashion and fun: Most of the atomizers on the market can only meet the needs of users for the suction function, which is monotonous. With the development of society, users' demands for atomizers are becoming more and more diversified. Users may require atomizers to have not only the atomization function, but also a certain fashion and fun.

[0006] 3. Technological innovation can no longer meet the ever-changing needs of users: With the development of society, users' demands for atomizers are becoming more and more diversified, and the simple technology used in traditional atomizers can no longer meet the ever-changing needs of users.

[0007] 4. Limited functions: Traditional atomizers have relatively simple functions, often only having basic smoke generation functions. They cannot provide additional functions such as screen smart reminders and motor vibration reminders.

[0008] 5. Insufficient health care: Traditional atomizers are often lacking in health care. They usually only focus on the production and taste of smoke, but ignore the care and protection of the user's physical health.

[0009] 6. Product firmware upgrade is not flexible and convenient enough: If the atomizers on the market need to be upgraded in firmware after they have been made into products, they can only be upgraded by disassembling the pcba board, and it is difficult to upgrade the firmware without connecting the battery, which wastes manpower and costs to a certain extent.

[0010] 7. Limited personalization: Most existing products use fixed designs and lack user customization options. Although some products offer limited color or style options, they cannot meet users' diverse needs for themes and appearances. [Summary of the invention]

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.

[0043] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] See also Figure 1The electronic atomization oral care system with dynamic interactive function of the present invention comprises a main control module, a MIC module, an LCD module, a voice module, a motor, a storage module, a key module and an atomization module, wherein the MIC module, the LCD module, the voice module, the motor, the storage module, the key module and the atomization module are respectively connected to the main control module.

[0045] The main control module is connected to a charging chip, the charging chip is connected to a battery, the battery is connected to an LDO voltage-stabilizing output module, and the LDO voltage-stabilizing output module is connected to the main control module.

[0046] The atomization module is connected with a microphone, and the microphone and the MIC module are respectively connected with an LDO voltage stabilization output module. The battery is connected with the atomization module.

[0047] The microphone is a suction microphone. The MIC module is a pickup microphone for collecting ambient sound.

[0048] The main control module adopts the AK32M0P030 model main control chip. In principle, other models of main control chips can be used to achieve the same function. The main control chip generally has common peripheral interfaces such as uart / usart, ADC, comparator, etc. The present invention uses the AK32M0P030 model main control chip as the main control chip of the electronic atomization oral care system, in which QFN32 packaging is used respectively. It is mainly responsible for the main control functions of the electronic atomization oral care system, such as the operation of the voice chip, button control, charge and discharge control, heating wire heating control and screen display control, whether the motor vibrates, etc., to ensure smooth communication and collaboration between the modules and the normal operation of the various functions of the electronic atomization oral care system.

[0049] The voice module adopts the AK50X model voice chip. When the atomization module is in the process of suction, the voice chip sends out a voice signal to remind the user after receiving the instruction from the main control module, thereby increasing the intelligence of the product.

[0050] The electronic atomization oral care system with dynamic interactive function of the present invention, in addition to the microphone with triggering suction function, also adds a sound pickup microphone for collecting external sounds. A transistor is used in the sound pickup microphone circuit to amplify the external sounds after they come in. When the sound signal is transmitted to the main control module, the main control module issues instructions to drive the LCD module to display the corresponding lighting effect after processing and analysis, so that the electronic atomization oral care system can change different lighting effects and pictures according to the external sounds, thereby increasing the fashion and interest of the product.

[0051] The present invention provides a microphone and a button for users to interact with the electronic atomization oral care system. Users trigger the microphone and the button to transmit data to the AK32M0P030 model main control chip, which analyzes the data and sends corresponding instructions after receiving the signal. For example, when the microphone that collects the sound of the external environment is triggered, the LCD module will display the corresponding lighting effects and pictures according to different sound effects.

[0052] The motor serves as one of the output devices. When the atomization module of the electronic atomization oral care system is in the suction process, the main control module will control the motor to initiate vibration of a certain frequency, which serves to remind the user and increases the interactivity with the user.

[0053] The electronic atomization oral care system with dynamic interactive function of the present invention includes a host, which is provided with a TYPE-C port. The host can be upgraded online through the TYPE-C port, and the finished product can be upgraded when powered by a battery, and the pcba mainboard can be upgraded when the battery is not connected.

[0054] The LCD module uses an LCD display screen for UI display, and the storage module is flash. Flash is used to store pictures and audio that the user wants to display. The user can store the pictures and audio that he wants to display in flash in advance. In fact, different types of screens such as LED digital tube display screens with different pins or starry sky screens, TFTP screens, etc. can be used to implement it according to the different UIs of the machine.

[0055] The present invention mainly displays the status information, power, oil, power level, corresponding lighting effects and pictures of the electronic atomization oral care system through the LCD module. The brightly colored LCD makes the interface of the electronic atomization oral care system clearer and more vivid. The AK32M0P030 chip will display the pictures stored in the flash on the LCD module according to the signals obtained by other modules, and control the screen to display the corresponding effects.

[0056] The LDO voltage-stabilizing output module is a special linear voltage regulator that can keep the output voltage stable when the input-output voltage difference is very small. It uses an error amplifier to compare the output voltage with a reference voltage (usually an accurate voltage generated internally), and adjusts the current through the power transistor according to the comparison result to keep the output voltage stable. In the present invention, the battery voltage can stably output a 3.3V voltage after passing through the LDO voltage-stabilizing output module to power the main control module and other modules.

[0057] The MOS with the model JXP1216DRG and the package information DFN2020-6L used in the atomizer module controls whether the heating wire works and protects the circuit. For example, when the atomizer module is in a high voltage or high current state, the MOS tube can control the switch of the circuit after receiving the instruction of AK32M0P030, thereby protecting against short circuit and open circuit.

[0058] The motor and AK50X voice chip also play output roles in the present invention. When the electronic atomization oral care system is in the suction process, the main control module will control the motor to initiate vibration of a certain frequency and send a signal to the voice chip. After receiving the signal, the voice chip will send a voice signal, which serves to remind the user.

[0059] The charging chip uses the AK4056H model chip, which is responsible for the charging function of the electronic atomization oral care system. It manages the battery charging process to ensure that the battery can be charged safely and efficiently. The charging chip communicates with the AK32M0P030, and then the main control chip controls the display of the screen to clearly inform the user of the charging status of the electronic atomization oral care system at this time.

[0060] Furthermore, AK32M0P030, as the core main control module of the electronic atomization oral care system, is responsible for the main judgment and control of the logic of the present invention. AK32M0P030 receives signals from buttons, AK4056H charging chip, suction microphone and microphone for collecting external environmental sound. After data processing and analysis, it sends instructions to drive the atomization module to work, control the LCD module to display the corresponding effect, control the motor to vibrate at a certain frequency, and the AK50X voice chip to send voice signals.

[0061] After receiving the signal from the AK32M0P030 main control module, the LCD module can drive the display of power, fuel, power level, corresponding lighting effects and pictures.

[0062] The AK4056H charging chip and battery are responsible for charging and powering the electronic atomization oral care system. The AK4056H charging chip also manages whether it is charging normally, whether the battery is overcharged, whether the charging current is too large, etc.

[0063] The button module is implemented by a patch or plug-in button. To simplify the user's operation, this system only sets one button, which transmits the signal to AK32M0P030 for judgment and processing through long press, short press, etc., so as to perform the corresponding function.

[0064] The MIC module is used to collect external sounds. A transistor is used in its internal circuit to amplify the external sounds. When the sound signal is transmitted to the main control module, the main control module issues instructions to drive the screen to display the corresponding lighting effects after processing and analysis, so that the electronic atomization oral care system can change different lighting effects according to external sounds.

[0065] The atomization module is composed of MOS and heating wire. Its main function is to heat the purified liquid and effectively atomize it, realizing the basic function of the atomization system. In this process, the heating wire plays a key role. It generates heat through battery power, causing the e-liquid to evaporate and form smoke. This module needs to be used with purification liquid.

[0066] The voice module receives instructions from the AK32M0P030 main control module. During the suction process of the atomizer module, after the voice chip receives the instructions from the main control module, it will send out a sound signal to remind the user.

[0067] The motor receives instructions from the AK32M0P030 main control module. During the suction process of the atomizer module, after receiving the instructions from the main control module, the motor will vibrate at a certain frequency to remind the user.

[0068] The user triggers the microphone by suction action, and the microphone sends the signal to AK32M0P030 for judgment and processing.

[0069] Flash stores the pictures and lighting effects that the user wants to display on the screen, and receives instructions from AK32M0P030. When the corresponding pictures are to be displayed and the corresponding audio is to be played, the flash will transmit the corresponding picture and audio data to the main control, which will then transmit it to the LCD screen for display and the voice chip to play the audio.

[0070] The working principle of the present invention is further described below in conjunction with specific principle diagrams.

[0071] See also Figure 2 , is the schematic diagram of the AK32M0P030 main control chip, QFN32 package. The VCC part of the main control chip requires 3.3V power supply (pin 4), and the power supply voltage is provided by an external battery.

[0072] The main control chip uses the SPI communication interface to connect to the ZB25VQ64C, and uses pins 10-13 (CS, SCLK, SO, SI) to read the program code stored in the flash chip to perform corresponding operations. It also writes the user's picture data into the flash chip for storage to meet the user's personalized needs.

[0073] AK32M0P030 is connected to the LCD screen through six signal lines, and sends a control signal through the LCD_EN enable pin (pin 25), which turns on the circuit of the LCD screen accordingly, so that the circuit can be turned on as needed to reduce power consumption; through the coordinated cooperation of the six signal lines, it is ensured that the MCU can correctly send commands and data to the LCD and control the LCD display to achieve personalized picture and lighting effect display:

[0074] a. LCD_CS (pin 10): Chip select signal interface, which is used to select whether to activate the LCD for data transmission. When LCD_CS is activated (usually low), the LCD will respond to the data or command sent by the MCU.

[0075] b. LCD_SCK (pin 5): Serial clock signal interface, used to synchronize data transmission between LCD and MCU. When LCD receives the clock signal, it will read or write data according to the specified timing.

[0076] c.LCD_SDA (pin 43): serial data interface, which is the main channel for MCU to send data or commands to LCD. Data is transmitted through LCD_SDA interface under the synchronization of LCD_SCK clock signal.

[0077] d.LCD_EN (pin 38): 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.

[0078] e. LCD_RS (pin 42): register selection interface, which is used to indicate whether the data currently received by the LCD is a command or display data. When LCD_RS is high, it means that the data being transmitted is a command; when it is low, it means that the data being transmitted is display data.

[0079] f.LCD_RST (pin 8): reset signal interface. When the MCU sends a reset signal to LCD_RST, the LCD will perform a reset operation. This usually occurs during power-on initialization or system reset to ensure that the LCD display is in a known and correct initial state.

[0080] The present invention has a voice interaction function. As can be seen in the schematic diagram, the MCU is connected to TG1 (pin 5), which acts as a switch button for the AUDIO part. When the MCU needs to play a voice prompt, the AUDIO part is triggered through this pin to start working and complete the voice prompt.

[0081] The user can operate the KEY (pin 9) simply and conveniently. The MCU can receive and process the signal sent by the 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.

[0082] The main control chip AK32M0P030 builds a basic atomization control system through MIC (pin 2), PWM2 (pin 29), ADC2 (pin 8), and RL2_CK2 (pin 3). MIC senses the user's inhalation action in real time and transmits the signal to the MCU to ensure that the MCU can respond promptly and accurately, while PWM2 controls the time and temperature of the heating element by adjusting the duty cycle of the PWM signal, thereby affecting the amount of smoke and taste, and then feeds back the temperature, duration and other signals to the MCU through the ADC pin for more precise control. The RL2_CK2 pin is used to detect the resistance of the heating wire before the system atomizes, and to detect potential problems (heating wire damage, aging, etc.) in time, so as to avoid adverse conditions during the atomization process.

[0083] At the same time, AK32M0P030 has two serial debugging interfaces: SWCLK (pin 23) and SWDIO (pin 24).

[0084] AK32M0P030 forms the power management part through AD_NTC, CHR_OK, CHR_ON, AD_BAT, LOW, and TDC. These pins each have different functions and together ensure that the power system of this system can work safely and efficiently.

[0085] a.PROG (pin 20): This pin is used to control whether the charging chip needs to charge the battery. When PROG receives a high level, the charging chip starts the charging function.

[0086] b.CHRG (pin 7) and STDBY (pin 8): These two pins are related to the charging function of the electronic atomization oral care system. When the electronic atomization oral care system is connected to the charger and starts charging, the STDBY pin will be activated to notify the MCU that the electronic atomization oral care system is currently charging. When charging is completed, the CHRG pin will be activated, indicating that the charging process has been successfully completed. The MCU can control the charging process of the electronic atomization oral care system according to the status of these two pins, and perform corresponding operations after charging is completed, such as disconnecting the charging circuit or displaying a prompt that charging is complete.

[0087] c.BAT_AD (pin 15): used to monitor the voltage of the battery of the electronic atomization oral care system. The MCU can know the remaining battery power in real time by reading the analog signal of the AD_BAT pin. According to the battery power, the MCU can adjust the working state of the electronic atomization oral care system, such as reducing the output power when the power is low or reminding the user to charge in time.

[0088] d.VIN_CK (pin 18): used to detect whether the charging voltage of the charging chip has reached the expected 5V charging voltage. When the charging voltage reaches 5V, the MCU outputs a high level.

[0089] Through the collaborative work of these pins and the MCU, the power management part of this system can realize functions such as temperature monitoring, charging control, and battery power monitoring to ensure that the electronic cigarette can work safely and stably.

[0090] See also Figure 3 , is a schematic diagram of the storage module. The present invention adopts ZB25VQ64C model, package information SOP8 as a flash chip with a storage capacity of 64M*1bit. It can store a variety of files, including images, color schemes, and user interface layouts, etc., to meet the user's needs to change the interface of the electronic atomization oral care system in real time according to personal preferences. Figure 3 This is the principle block diagram of ZB25VQ64C. The 3V3A pins are connected to LCD, AUDIO, and SPK, so that when the MCU lets the LCD read data or commands, a closed-loop circuit is formed to trigger the flash chip to work, retrieve and display the flash chip information content, and play the corresponding voice at the same time. The design of incorporating the flash chip can not only reduce the storage burden of the MCU, but also increase the speed of information reading, making the display of the electronic cigarette smoother and faster.

[0091] a. Flash_CS: Chip selection signal, used to select or activate the flash memory chip. When the Flash_CS signal is activated, it means that the flash memory is currently communicating with the main control chip.

[0092] b. Flash_MISO: 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.

[0093] c. Flash_SCK: Serial clock signal, used to synchronize data transmission between the flash memory and the main control chip. The Flash_SCK signal defines the rate and timing of data transmission.

[0094] d. Flash_MOSI: 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.

[0095] These pins work together to ensure that the main control chip of the electronic atomization oral care system can correctly communicate with the flash memory to realize data reading, writing and storage.

[0096] See also Figure 4 and Figure 5 , which are the audio processing module (Audio) and the speaker module (SPK) of the voice module. The audio processing module is composed of the voice chip AK50X, and the speaker module is composed of AK8002D. When the electronic atomization oral care system is in the process of suction, it provides users with audio feedback and operation prompts. When the MCU needs to play audio, it sends the corresponding instructions and data to the Audio part through the TG1 IO port, triggering the Audio part to start processing the audio data (the sound effects, prompt sounds or voice commands pre-stored in the FLASH chip, etc., are transmitted through the 3V3AIO port), and convert the data into an analog audio signal through the DAC IO port. The CTRL IO port opens the SPK part. After the SPK part receives the control signal of CTRL and the analog audio signal of DAC, it starts to play the sound.

[0097] The SPK part uses an audio power amplifier IC with shutdown mode, model AK8002D, SOP8 package, which is suitable for this atomization system. It can reduce power consumption by controlling the shutdown mode. AK8002D works stably, with a gain bandwidth product of up to 2.5MHz and stable unity gain. From the principle, it can be seen that the analog audio signal converted by DAC can further eliminate the noise and the noise coupled from the input end through the DC blocking capacitor C10, providing users with a better voice experience.

[0098] See also Figure 6 , is the schematic diagram of the MIC module. In the schematic diagram, the MIC module receives external sound signals through the pickup microphone, and after capacitor filtering and transistor amplifier amplification, transmits the signal to the MCU through the MIC_AD pin. After MCU analyzes and processes, it sends relevant instructions to the LCD module. A MOS tube is also added to the circuit to achieve low power consumption.

[0099] See also Figure 7 , is the motor schematic diagram. One end of the motor is connected to the power supply and the other end is connected to the MOTOR_IO pin of the MCU. The motor receives instructions from the MCU. When the MCU detects that the atomization system is inhaling, it outputs a high level to the motor module through the MOTOR_IO pin. At this time, the motor will vibrate at a certain frequency.

[0100] See also Figure 8 , is a schematic diagram of the charging chip, and the charging chip AK4056H is used as the charging chip in the host of the present invention.

[0101] See also Fig. 9 , is the schematic diagram of the LCD module. As shown in the figure, the screen interface receives signals from the MCU, and the MCU issues specific instructions to drive the LCD screen to display specific lighting effects and pictures. The LCD screen is connected to the AK32M0P030 through six signal lines, and receives control signals through the LCD_EN enable pin, and accordingly turns on the circuit of the LCD screen, so that the circuit can be turned on as needed to reduce power consumption; through the coordinated cooperation of the six signal lines, it ensures that the MCU can correctly send commands and data to the LCD and control the LCD display to achieve personalized picture and lighting effect display.

[0102] See also Fig.10 , is the MIC circuit schematic diagram of the MIC module. The MIC is directly powered by the battery. The voltage output pin of the MIC is connected to the GPIO2 pin of the AK030 chip. When the user triggers the suction microphone, the MIC pin outputs a high level. After the MCU receives the signal, it will control the atomization module to start working, triggering the heating wire to heat the e-liquid to produce an atomization effect. It will also control the LCD module to display the corresponding picture and the voice chip to play the corresponding audio, providing users with a convenient smoking experience.

[0103] See also Fig.11 , is the schematic diagram of the atomization module, which uses the JXP1216DRG MOS tube, supports a maximum current of 16A and a maximum voltage of 12V. When the user uses the atomization system, the MCU receives the instruction and outputs the corresponding pulse signal through the PWM2 pin to control the conduction of the MOS tube. When the MOS tube is turned on, the battery's electrical energy flows through it to the heating wire, causing the heating wire to generate heat. This heat then heats the e-liquid, causing it to evaporate quickly and produce an atomization effect. By precisely controlling the duty cycle and frequency of the PWM signal, the MCU can achieve precise adjustment of the heating power of the heating wire to achieve the purpose of providing different concentrations and tastes of smoke according to the user's smoking habits and needs. In addition, the JXP1216DRG also feeds back signals such as temperature and duration to the MCU through the ADC pin for more precise control, providing users with a personalized smoking experience.
