Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments.

[0044] In some embodiments, as shown in Figure 1 A control circuit of an atomization device is provided, the atomization device includes an atomization device body 100 and an atomization device part 200, the atomization device part 200 and the atomization device body 100 are detachably connected, and the control circuit includes:

[0045] The first module 101 is located in the atomization device body 100, and the first module 101 comprises a first MCU 103 and a first wireless communication module 104, and the first MCU 103 is connected with the first wireless communication module 104;

[0047] The first MCU 103 and the second MCU 105 transmit data information through the first wireless communication module 104 and the second wireless communication module 106.

[0048] The first module 101 is located in the atomization device body 100, and the first MCU 103 (master control unit) implements the control and management of the whole device, including power adjustment, temperature control, battery management and user interaction. The first wireless communication module 104 is used for wireless communication with the second module 102, and realizes data interaction, such as state synchronization, control instruction transmission and the like.

[0049] The working process of the technical solution is as follows: when the user installs the detachable atomization device body 200, the second MCU 105 sends a connection request to the first MCU 103 through the second wireless communication module 106. After the first MCU 103 receives the request, it confirms the connection and performs device information synchronization, such as atomization cartridge status, battery capacity, etc. The second MCU 105 is responsible for monitoring the temperature of the atomization cartridge, battery capacity and other parameters, and periodically transmits data to the first MCU 103 through the second wireless communication module 106.

The user can check the device status through the buttons or display screen of the device body, and the first MCU 103 can also send adjustment instructions (such as adjusting temperature, power, etc.) to the second MCU 105. When the user starts the atomization device, the first MCU 103 sends a heating instruction to the second MCU 105, and the second MCU 105 controls the heating element to start and monitors the heating temperature in real time. If the temperature exceeds the set threshold, the second MCU 105 can immediately adjust the heating power and send an alarm message to the first MCU 103 to prevent overheating or safety risks. The first MCU 103 adjusts the overall power output according to the received data to ensure stable atomization effect. When the user disassembles the atomization device body 200, the second MCU 105 notifies the first MCU 103 to disconnect and turn off related functions to ensure safety.

[0050] It should be noted that the atomization device body 200 and the atomization device body 100 are designed for detachable connection, which can be easily replaced or independently maintained. The connection methods include but are not limited to the following embodiments:

[0055] As an implementation manner, as shown in Figure 2 The first wireless communication module 104 includes:

[0056] The first wireless output module 141, whose input end is connected to the first output end of the first MCU 103, is configured to output data information to the second module 102;

[0057] The first wireless input module 142, whose output end is connected to the first input end of the first MCU 103, is configured to receive the data information output by the second module 102.

[0058] The first wireless output module 141 is configured to send control instructions and data to the second module 102, and the first wireless output module 141 transmits the control instructions (such as heating power setting, temperature adjustment, start / stop atomization) of the first MCU 103 and sends the device state information (such as working mode, battery management strategy). The first wireless input module 142 is configured to receive the data information from the second module 102, and the first wireless input module 142 receives the real-time data (such as heating body 109 temperature, fault state) fed back by the second module 102; analyzes the received data and transmits the data to the first MCU 103 for decision and adjustment, monitors the connection state of the second module 102, ensures the normal operation of the device, and triggers the safety protection mechanism when disconnected.

[0059] The working process of the embodiment is as follows: after the second module 102 is connected to the atomization device body 100, the second module 102 sends a connection request signal, the first wireless input module 142 receives the request and transmits it to the first MCU 103; the first MCU 103 sends a signal through the first wireless output module 141 to complete wireless pairing with the second module 102 and establish a data interaction channel; the first MCU 103 sends control instructions such as heating power setting, temperature adjustment, working mode, etc. through the first wireless output module 141. The second wireless communication module 106 receives the instructions and transmits them to the second MCU 105, and the second MCU 105 performs corresponding operations; the second MCU 105 monitors data such as atomization chamber temperature and battery power and sends the data through the second wireless communication module 106. The first wireless input module 142 receives the data and transmits them to the first MCU 103, and the first MCU 103 adjusts according to the feedback information, such as optimizing the heating strategy or prompting the battery power shortage.

[0060] The technical effect of the embodiment is that through the cooperative work of the first wireless output module 141 and the first wireless input module 142, efficient wireless communication between the atomization device body 100 and the detachable module is realized; control instructions and state data can be transmitted in real time, so that the first MCU 103 can accurately regulate and control the heating power, temperature management and working mode, and at the same time receive the temperature, battery power and fault state information fed back by the second module 102, thereby optimizing the device operation strategy.

[0061] As an embodiment, as shown in Figure 2 The second wireless communication module 106 includes:

[0062] The second wireless output module 162 is connected to the first output end of the second MCU 105 to output data information to the first module 101; the second wireless input module 161 is connected to the first input end of the second MCU 105 to receive the data information output by the first module 101.

[0063] The second wireless output module 162 sends data to the first module 101, and the second wireless output module 162 transmits the key state information collected by the second MCU 105, such as the atomization chamber temperature, the running state or fault alarm of the heating element, etc. Feedback device operation parameters so that the first MCU 103 can optimize power management, temperature adjustment and other functions. The second wireless input module 161 receives control instructions of the first module 101, such as atomization start / stop, heating power setting, working mode adjustment, etc., analyzes the received data and transmits them to the second MCU 105 for execution, to ensure that the atomization process meets the set requirements.

[0064] The working process of the embodiment is as follows: after the device is started, the first MCU 103 sends a control instruction through the first wireless output module 141, the second wireless input module 161 receives the instruction and transmits it to the second MCU 105 for execution. The second MCU 105 monitors the temperature of the atomization chamber, the heating power and other data, and feeds back to the first wireless input module 142 through the second wireless output module 162, so that the first MCU 103 can make real-time adjustment.

[0065] The technical effect of the embodiment is that through the cooperative work of the second wireless output module 162 and the second wireless input module 161, efficient bidirectional wireless communication between the atomization device body 100 and the detachable module is realized; this scheme enables the second MCU 105 to feed back the atomization chamber temperature, heating power and device running state information to the first MCU 103 in real time, so that the first MCU 103 can dynamically optimize power management and temperature adjustment, and improve the atomization effect and energy efficiency. At the same time, the second wireless input module 161 ensures that the control instruction sent by the first MCU 103 can be accurately transmitted to the second MCU 105 and executed, ensuring that the device operates according to the set requirements. This technical scheme improves the intelligent level and response speed of the device, and at the same time, without traditional physical contacts and connecting lines, it reduces mechanical wear and tear, enhances the durability and safety of the device, and optimizes the user experience.

[0066] As an embodiment, as shown in Figure 3 the first wireless output module 141 is a first optical signal output module for generating and sending a first optical signal; the second wireless input module 161 is a first optical signal processing module for receiving and decoding the first optical signal; the second wireless output module 162 is a second optical signal output module for generating and sending a second optical signal; and the first wireless input module 142 is a second optical signal processing module for receiving and decoding the second optical signal.

[0067] The first optical signal output module generates and sends a first optical signal, which is used to transmit information to the first optical signal processing module. The first optical signal output module can use a light source such as a laser, an LED, an infrared light, etc., and select a suitable optical signal according to application requirements. The first optical signal processing module receives and decodes the first optical signal, converts the optical signal into an electronic signal or a control signal for subsequent processing, and is mainly used to receive the optical signal sent from the first optical signal output module and extract data information therein. The first optical signal processing module can be a photodetector such as a photoresistor, a photodiode, a photomultiplier tube, etc. The second optical signal output module generates and sends a second optical signal, which is used to transmit information to the second optical signal processing module to realize bidirectional communication. The second optical signal processing module receives and decodes the second optical signal, and converts the second optical signal into an electronic signal or a control signal. This module receives the optical signal sent from the second optical signal output module, extracts feedback data or control information, and realizes bidirectional interaction.

[0068] The technical effect of the embodiment is that through the cooperative work of the first optical signal output module, the first optical signal processing module, the second optical signal output module and the second optical signal processing module, bidirectional wireless transmission and decoding of optical signals are realized. Compared with the traditional radio communication mode, data transmission using optical signals has the advantages of strong anti-electromagnetic interference ability, high transmission rate and good confidentiality.

[0069] As an embodiment, as shown in Figure 4 The first optical signal output module 141 includes a first light-emitting diode D1 and a first resistor R1. One end of the first resistor R1 is the input end of the first optical signal output module 141, the other end of the first resistor R1 is connected to the cathode of the first light-emitting diode D1, and the anode of the first light-emitting diode D1 is connected to a power supply voltage VCC. The second optical signal processing module 142 includes a first light-receiving tube Q1 and a second resistor R2. One end of the second resistor R2 receives the power supply voltage VCC, the other end of the second resistor R2 and the collector of the first light-receiving tube Q1 are commonly connected as the output end of the second optical signal processing module 142, and the emitter of the first light-receiving tube Q1 is grounded.

[0070] The first light signal output module 141 is used for sending a control signal, and the first light emitting diode D1 is used as a light signal sending element. When the first MCU 103 outputs a low-level signal, the first light emitting diode D1 is lit and emits a specific light signal (usually infrared light) to the outside, which is used for transmitting a control instruction or data to the second light signal processing module 142. The first resistor R1 is used for current limiting, which ensures that the first light emitting diode D1 works in a suitable current range, avoids overcurrent damage, and stabilizes the output intensity of the light signal and improves the transmission reliability. The second light signal processing module 142 is used for receiving a control signal, and the first phototransistor Q1 is used for receiving the light signal emitted by the light emitting diode in the second module 102. When the second light emitting diode D2 in the second module 102 is lit, the first phototransistor Q1 is turned on by the light, and the signal is transmitted to the subsequent circuit, thereby completing the reception of the wireless data. The second resistor R2 is used as a pull-up resistor, which ensures that the output end of the second light signal processing module 142 maintains a high level when the first phototransistor Q1 does not receive a light signal; when the first phototransistor Q1 is turned on, the output end level is lowered, so that the first MCU 103 can correctly analyze the received signal.

[0071] The working principle of the embodiment is that the first MCU 103 controls the lighting and extinguishing of the first light emitting diode D1, and encodes the control instruction or data through the light and dark changes of the light signal. The first resistor R1 limits the current of the first light emitting diode D1, which ensures the stability of the light signal intensity and is not affected by the power voltage fluctuation. When the second light emitting diode D2 in the second module 102 emits light, the first phototransistor Q1 is turned on after receiving the light signal, and the output end voltage is lowered. The first MCU 103 detects a low-level signal, that is, receives the corresponding control instruction or data. When the light emitting diode in the second module 102 is extinguished, the first phototransistor Q1 is cut off, and the output end is restored to a high level, forming a “0” or “1” change of the digital signal, thereby realizing the wireless data transmission. The second resistor R2 provides a stable high level when the phototransistor is not turned on, which ensures the accuracy of signal analysis.

[0072] The technical effect of the embodiment is that the wireless data transmission between the first MCU 103 and the second MCU 105 is realized through the light signal communication mode, which avoids the problems of multiple physical contacts and connection lines in the traditional contact connection, improves the durability of the device and the reliability of the signal transmission; the first light emitting diode D1 and the first phototransistor Q1 are used to encode and analyze the control signal through the light and dark changes, which ensures the stability of the data transmission; the first resistor R1 and the second resistor R2 are respectively used for current limiting and pull-up, which ensures the stability of the light signal intensity and the signal accuracy of the receiving end.

[0073] As an example, as Figure 4As shown, the first light signal processing module 161 includes a second light receiving tube Q2 and a third resistor R3, one end of the third resistor R3 receives a power supply voltage VCC, the other end of the third resistor R3 and the collector of the second light receiving tube Q2 are commonly connected as the output end of the first light signal processing module 161, and the emitter of the second light receiving tube Q2 is grounded; the second light signal output module 162 includes a second light emitting diode D2 and a fourth resistor R4, one end of the fourth resistor R4 is the input end of the second light signal output module 162, the other end of the fourth resistor R4 is connected to the cathode of the second light emitting diode D2, and the anode of the second light emitting diode D2 is connected to the power supply voltage VCC.

[0074] The first light signal processing module 161 is used to receive the control instruction of the first module 101, and the second light receiving tube Q2 receives the light signal emitted by the first light emitting diode D1. When the first light emitting diode D1 is on, the second light receiving tube Q2 is turned on by light, the output end voltage is lowered, the received light signal is converted into an electrical signal, and the electrical signal is transmitted to the second MCU 105. When the first light emitting diode D1 is off, the second light receiving tube Q2 is cut off, and the output end voltage returns to a high level; the third resistor R3 acts as a pull-up resistor, keeps the output end of the first light signal processing module 161 at a high level when the second light receiving tube Q2 is not conducting (no light signal is received), and ensures signal stability. When the second light receiving tube Q2 is conducting, the output end voltage is lowered, so that the second MCU 105 can correctly identify the signal change. The second light signal output module 162 is used to send device state data to the first module 101, the second light emitting diode D2 acts as a light signal transmitting element, converts the data signal of the second MCU 105 into a light signal and sends it to the first light receiving tube Q1. When the second MCU 105 outputs a low level, the second light emitting diode D2 emits a light signal, indicating that there is data transmission. When the second MCU 105 outputs a high level, the second light emitting diode D2 is off, indicating that there is no signal transmission. The fourth resistor R4 acts as a current limiting resistor to prevent damage caused by excessive LED current and control the luminous intensity to ensure the stability of the light signal.

[0075] Specifically, as shown in the figure, Figure 4 The first MCU 103 sends data to the second MCU 105:

[0076] The first MCU 103 outputs a low level signal TXA, the first light emitting diode D1 is conducting and emitting light, and the second light receiving tube Q2 receives the signal and conducts to ground, outputting a low level signal RXB.

[0077] The first MCU 103 outputs a high level signal TXA, the first light emitting diode D1 is not conducting, the second light receiving tube Q2 is not conducting, and the signal RXB is pulled up to a high level by the pull-up resistor R3.

[0078] The second MCU 105 sends data to the first MCU 103:

[0079] The second MCU 105 outputs a low-level signal TXB, the second light-emitting diode D2 is turned on to emit light, the first light-receiving tube Q1 receives the signal to turn on, and outputs a low-level signal RXA.

[0080] The second MCU 105 outputs a high-level signal TXB, the second light-emitting diode D2 is not turned on, the first light-receiving tube Q1 is not turned on, and the signal RXA is pulled high to a high level by the pull-up resistor R2.

[0081] As an embodiment, as shown in Figure 5 The first module 101 further includes a first power terminal 121, the first power terminal 121 is connected to the battery module 120, the second module 102 further includes a second power terminal 122, and when the second module 102 is connected to the atomization device body 100, the second power terminal 122 is connected to the first power terminal 121.

[0082] The battery module 120 serves as the energy source of the entire atomization device, responsible for providing stable working voltage to the first MCU 103 to ensure normal operation of the device. Through the connection of the first power terminal 121 and the second power terminal 122, power is supplied to the second MCU 105, enabling the second module 102 to work independently. The first power terminal 121 serves as the power interface between the device body and the second module 102, and when the second module 102 is connected, it provides power to the second MCU 105 through the second power terminal 122. The second power terminal 122 is a power supply interface for the second module 102, which is connected to the first power terminal 121 when the atomization device body 200 is connected to the atomization device body 100, achieving power transmission and supplying power to the second MCU 105, so that the atomization device body 200 and the atomization device body 100 can work normally without the need for an independent battery, improving the integration design of the system.

[0083] The technical effect of the present embodiment is that through the cooperative design of the battery module 120, the first power terminal 121 and the second power terminal 122, unified power supply of the atomization device body 100 and the atomization device body 200 is achieved, ensuring stable operation of the device. This scheme eliminates the need for an independent battery for the atomization device body 100, simplifies the system structure, reduces costs, and avoids the complexity of battery management. This design supports modular expansion, allowing the device to flexibly replace or upgrade detachable modules, enhancing the adaptability and user experience of the system.

[0084] As an embodiment, as shown in Figure 6As shown, the first module 101 also includes a button module 107, the output of which is connected to the second input of the first MCU 103. The second module 102 also includes a power output module 108 and a heating element 109. The second output of the second MCU 105 is connected to the control terminal of the power output module 108, and the output of the power output module 108 is connected to the heating element 109.

[0085] The button module 107 is used for user input of power settings (such as adjusting heating power, turning the atomizing device on / off), and transmits the user-set power information to the first MCU 103. The first MCU 103 processes the power setting information input by the button module 107 and sends it to the second module 102 through the first wireless output module 141 to monitor and adjust the power output during the atomization process and optimize the device's operating status. The first wireless output module 141 wirelessly sends the power setting information processed by the first MCU 103 to the second module 102 to control the heating element 109. The second wireless input module 161 receives the power setting information sent by the first wireless output module 141 and transmits it to the second MCU 105. The second MCU 105 (slave control unit) parses the received power information and adjusts the power output of the heating element 109 according to the set value, controlling the power output module 108 through the second output terminal to drive the heating element 109 to work. The power output module 108, as the driving unit of the heating element 109, adjusts the output power according to the control signal of the second MCU 105 to achieve precise heating control. The heating element 109 provides atomization heating function, heating according to the energy provided by the power output module 108 to achieve atomization effect.

[0086] The technical advantages of this embodiment are as follows: Through the collaborative operation of the button module 107, the wireless communication module, and the dual MCUs, intelligent power control of the atomizing device is achieved. The user can set the heating power via the button module 107. After receiving and processing the input information, the first MCU 103 transmits the set value to the second MCU 105 via wireless communication, ensuring precise control of the heating element 109. The second MCU 105 analyzes the power information and drives the power output module 108 to precisely adjust the power output of the heating element 109, optimizing the atomization effect. This solution improves the flexibility and intelligence of the device, achieves stable and precise power regulation, enhances the user experience, and eliminates the need for traditional physical contacts and connecting wires, reducing mechanical wear and improving the durability and reliability of the device.

[0087] As one implementation method, such as Figure 7 As shown, the first module 101 also includes a driving module 110 and a display screen 111. The second output terminal of the first MCU 103 is connected to the input terminal of the driving module 110, and the output terminal of the driving module 110 is connected to the input terminal of the display screen 111.

[0088] The driving module 110 serves as an interface between the first MCU 103 and the display screen 111, receives the control signal of the first MCU 103, and drives the display screen 111 to work. The driving module 110 analyzes the power information output by the first MCU 103 and converts it into a signal format suitable for the display screen 111, to ensure the correctness and stability of the display content. The display screen 111 displays the working state of the atomization device in real time, including the current heating power, working mode, battery capacity and other information. When the second module 102 enters the heating state, the corresponding power setting value is displayed, so that the user can intuitively understand the working state of the device. OLED, LCD or LED digital tube display technology can be used to provide clear and readable information and improve user experience.

[0089] The technical effect of the present embodiment is that the combination of the driving module 110 and the display screen 111 realizes the real-time information visualization of the atomization device, improves the user experience and the intelligent level of the device, and ensures that the power information output by the first MCU 103 is correctly analyzed and transmitted to the display screen 111, so that the device can display the key state information such as heating power, working mode and battery capacity in real time during the heating process. The user can intuitively understand the operation of the device, adjust the use parameters conveniently, and improve the interactive experience.
