[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] In related technologies, these electronic atomizers use a heating element to heat and atomize the internally stored atomizing liquid into an aerosol, allowing users to utilize these gases at any time. Additionally, some advanced electronic atomizers can store atomization data generated during the atomization process. However, this approach still suffers from limitations in the practicality and functionality of electronic atomizers.

[0039] To address this, this application provides an atomizing circuit comprising a connection interface, a processing unit, a storage module, and an atomizing module. The first and second data terminals of the connection interface are connected to the first and second data terminals of the processing unit, respectively; each second communication terminal of the processing unit is connected to each data terminal of the storage module; and the control terminal of the processing unit is connected to the atomizing module. Specifically, the connection interface connects to an external device for data transmission between the processing unit and the external device. The processing unit reads data from the storage module, writes data to the storage module, stores atomizing data from the atomizing module and external data written from the external device, and outputs a PWM signal to the atomizing module. The atomizing module outputs a level signal to the processing unit, which in turn causes the processing unit to output the PWM signal. This allows for the storage of external data in the atomizing circuit via the connection interface and the extraction of atomizing data or control parameters from the atomizing circuit, thereby enhancing the practicality and functional versatility of the electronic atomizer.

[0040] This application uses an atomization circuit applied in an electronic atomizer as an example for illustration. However, it does not imply that this application's embodiments can only be applied to electronic atomizers to achieve atomization and storage functions.

[0041] The atomizing circuit provided in the embodiments of this application will be explained in detail below.

[0042] Figure 1 A schematic diagram of an atomizing circuit provided in this application. See also... Figure 1 This application provides an atomizing circuit 100, which includes a connection interface 101, a processing unit 102, a storage module 103, and an atomizing module 104.

[0043] The first data terminal of the connection interface 101 is connected to the first communication terminal of the processing unit 102.

[0044] Each second communication terminal of the processing unit 102 is connected to each data terminal of the storage module 103, and the control terminal of the processing unit 102 is connected to the atomizing module 104. Specifically, the control terminal of the processing unit 102 includes a first control terminal and a second control terminal, which are respectively connected to the atomizing module 104.

[0045] The connection interface 101 is used to connect to an external device to transmit data between the processing unit 102 and the external device.

[0046] The processing unit 102 is used to read data from the storage module 103, write data to the storage module 103, and output PWM signals to the atomization module 104.

[0047] The storage module 103 is used to store the atomization data of the atomization module 104, as well as external data written from the external device.

[0048] The atomization module 104 is used to output a level signal to the processing unit 102, which causes the processing unit 102 to output the PWM signal.

[0049] Under normal circumstances, the atomization module 104 can generate and output a level signal to the processing unit 102 when the user performs the corresponding atomization function trigger operation, when the gas flow rate around the atomization module 104 changes, or when other conditions determine that atomization is needed.

[0050] In one embodiment, the connection interface 101 can be any type of interface, such as a Universal Serial Bus (USB), specifically a Type-A, Type-B, or Type-C interface, or any other interface capable of supporting data transmission. Furthermore, besides supporting data transmission, the connection interface 101 can also perform any other possible functions, such as charging. This application does not limit this aspect.

[0051] In one embodiment, the external device can be any possible terminal device, such as a smartphone, tablet, computer, laptop, etc., and this application embodiment does not limit it.

[0052] Furthermore, after the external device is connected to the connection interface 101, each communication terminal of the external device can be connected to the first communication terminal of the processing unit 102 in the atomization circuit 100 through the connection interface 101. In this way, the external device can write data to or read data from the storage module 103 through the processing unit 102.

[0053] Specifically, the external device can read external data stored in the storage module 103, or it can read atomization data stored in the storage module 103. This application embodiment does not limit this.

[0054] Generally, the number of first data terminals of the connection interface 101 can be one or more. Furthermore, the number of first communication terminals of the processing unit 102 can be the same as the number of first data terminals of the connection interface 101. Specifically, this can be adjusted according to the data transmission method between the processing unit 102 and the external device; this embodiment does not limit this.

[0055] Specifically, data can be transmitted between the external device and the processing unit 102 via serial differential signals, or via parallel signals or any other possible means. This application embodiment does not limit this.

[0056] For example, assuming that data is transmitted between the external device and the processing unit 102 via serial differential signals, this embodiment also provides a possible connection method between the connection interface 101 and the processing unit 102. See also... Figure 1 In this case, the connection interface 101 may have two first data terminals, namely data terminal O1 and data terminal O2, and the processing unit 102 may also have two first communication terminals, namely communication terminal O3 and communication terminal O4.

[0057] from Figure 1 As can be seen, data terminal O1 is connected to communication terminal O3 via communication line L1, and data terminal O2 is connected to communication terminal O4 via communication line L2. Specifically, when the external device and processing unit 102 exchange data through connection interface 101, communication lines L1 and L2 are used to transmit positive voltage signals and negative voltage signals, respectively. In this way, serial differential signals can be transmitted between the external device and processing unit 102.

[0058] Understandable Figure 1The connection method between the connection interface 101 and the processing unit 102 shown is merely an example and does not mean that the atomizing circuit 100 provided in this embodiment can only be configured in this way. If the external device and the processing unit 102 transmit data through other means, the first data terminal of the connection interface 101 and the first communication terminal of the processing unit 102 can also be adaptively set to one, three, or any other possible number, and a corresponding number of communication lines can be provided between the connection interface 101 and the processing unit 102 to connect them. This embodiment does not limit this.

[0059] Generally, the interface on the external device is a female port. To facilitate plugging and unplugging the connection interface 101 from the external device, the connection interface 101 can generally be set to a male port, or it can be set to a female port and a converter cable can be used to connect the connection interface 101 to the external device. This application embodiment does not limit this.

[0060] In one embodiment, the processing unit 101 can be any component with functions such as calculation, processing, and control. For example, it can be any possible component such as a microcontroller unit (MCU), a central processing unit (CPU), or a digital signal processing chip (DSP). This application embodiment does not limit this.

[0061] Specifically, the processing unit 101 and the storage module 103 can transmit data via parallel signals and / or a Serial Peripheral Interface (SPI). That is, the processing unit 101 can also have the function of converting data formats, for example, converting data transmitted by the storage module 103 in parallel signals into serial differential signals that the external device can recognize and read, or converting data transmitted by the external device in serial differential signals into parallel signals or SPI signals that the storage module 103 can recognize. This application embodiment does not limit this aspect.

[0062] In one embodiment, the storage module 103 can be any possible storage device, and the storage module 103 may include at least one memory, which may be a Flash memory. This application embodiment does not limit this.

[0063] In one embodiment, the atomization data may include any possible data such as the current operating voltage, atomization rate, and remaining capacity of the atomizing liquid detected by the atomization module 104.

[0064] In one embodiment, the storage module 103 may also store any external data written by the external device.

[0065] For example, the external data can be data of any format, such as text data, audio data, video data, etc. Additionally, the storage module 103 can also store firmware and / or control parameters required for each component in the atomization circuit 100 to perform any possible functions such as atomization, charging, display, and sound output. This application embodiment does not limit this aspect.

[0066] In one embodiment, the atomizing module 104 can refer to a device for atomizing the atomizing liquid corresponding to the atomizing circuit 100, so that the atomizing liquid becomes a gas.

[0067] In one embodiment, the level signal can be a digital signal. This level signal can be used to indicate the flow rate of the gas around the atomizing module 104, whether atomization has begun, and / or the user-desired atomization rate. Generally, if the level signal can indicate the gas flow rate, then the higher the gas flow rate, the higher the voltage value corresponding to the level signal can be; however, this embodiment does not limit this.

[0068] In one embodiment, the PWM signal can be a signal used to control the atomization rate. Generally, the larger the duty cycle of the PWM signal, the faster the atomization module 104 atomizes the liquid. This application does not limit this aspect.

[0069] It is worth noting that, in order to better explain the atomizing circuit 100 provided in the embodiments of this application, the working principle of the atomizing circuit 100 is described below:

[0070] When the connection interface 101 is not connected to the external device, or when the external device and the atomizing circuit 100 do not exchange data, the first communication terminal of the processing unit 102 will not transmit data. At this time, the atomizing circuit 100 only needs to perform the atomizing function.

[0071] Specifically, if the circuit 100 is in the default state or does not need to atomize at present, the atomization module 104 will not output the level signal, and the processing unit 102 will not output the PWM signal. At this time, the atomization module 104 will not perform any operation on the atomizing liquid.

[0072] If the gas flow rate changes or a user triggers the operation, the atomizing module 104 can output the level signal to the processing unit 102, causing the processing unit 102 to output the PWM signal to the atomizing module 104. When the atomizing module 104 receives the PWM signal, it can atomize the liquid into gas through heating, pressurization, sound waves, or other methods. In this way, the atomizing function of the atomizing circuit 100 can be realized.

[0073] When the connection interface 101 is connected to the external device and the external device needs to exchange data with the atomizing circuit 100, if the external device needs to write data to the storage module 103, the external device can send a data write command to the processing unit 102, and then transmit the data to the first communication terminal of the processing unit 102 through the connection interface 101 in the form of a serial differential signal. After the processing unit 102 receives the data, it can convert the data format (for example, convert it into a parallel signal or SPI signal that the storage module 103 can recognize), and output the converted data to the storage module 103 through the second communication terminal of the processing unit 102. In this way, the purpose of writing data from the external device to the circuit 100 can be achieved.

[0074] If the external device needs to read data from the storage module 103, it can first send a data read command to the processing unit 102 through the connection interface 101. The processing unit 102 then controls the storage module 103 to transmit data to the processing unit 102 in the form of parallel signals or SPI signals. Then, the processing unit 102 converts the data into a serial differential signal that the external device can recognize, and transmits the converted data to the external device through the first communication terminal of the processing unit 102 and the connection interface 101. In this way, the purpose of the external device reading data from the circuit 100 can be achieved.

[0075] It is worth noting that, as can be seen from the above, the atomizing circuit 100 provided in this application embodiment can not only realize the atomization function of the atomizing liquid, but also realize the function of writing data from external devices into the storage module 103 in the atomizing circuit 100, and / or enabling external devices to read data from the storage module 103 in the atomizing circuit 100. That is, the atomizing circuit 100 provided in this application embodiment can also be used as a memory. In this way, a data storage function can be added to the original atomization function of the atomizing circuit 100. That is, it can realize the function of storing external data into the atomizing circuit 100 through the connection interface 101, and storing or reading atomized data in the atomizing circuit 100, thereby improving the practicality and functional diversity of the electronic atomizer.

[0076] In this embodiment, a connection interface 101, a processing unit 102, a storage module 103, and an atomizing module 104 are provided in the atomizing circuit 100. The first data terminal of the connection interface 101 is connected to the first communication terminal of the processing unit 102. Each second communication terminal of the processing unit 102 is connected to each data terminal of the storage module 103, and the first control terminal and the second control terminal of the processing unit 102 are respectively connected to the atomizing module 104.

[0077] Specifically, the connection interface 101 is connected to an external device to transmit data between the processing unit 102 and the external device; the processing unit 102 reads data from the storage module 103, writes data to the storage module 103, and outputs a PWM signal to the atomization module 104; the storage module 103 is used to store the atomization data of the atomization module 104 and the external data written from the external device. Additionally, the atomization module 104 outputs a level signal to the processing unit 102, which causes the processing unit 102 to output the PWM signal, thus enabling the atomization circuit to have a data storage function.

[0078] In other words, the atomizing circuit 100 provided in this application embodiment can realize the functions of writing or reading external data into the storage module 103 through the connection interface 101, and reading the atomizing data stored in the storage module 103. In this way, the practicality and functional diversity of the electronic atomizer can be improved.

[0079] In one possible implementation, the processing unit 102 may disable its first communication terminal and / or second communication terminal when outputting the PWM signal; or it may disable its first control terminal and / or second control terminal when exchanging data with the storage module 103. This ensures that the atomizing circuit 100 only performs atomization or data read / write operations at any given time, preventing malfunctions in the storage and / or atomization functions of the atomizing circuit 100 due to excessive processing pressure on the processing unit 102.

[0080] It is understood that the processing unit 102 can also simultaneously output the PWM signal and exchange data with the external device and / or storage module 103. This can improve the practicality of the atomization circuit 100.

[0081] In one possible implementation, see [link to relevant documentation]. Figure 2 The storage module 103 includes a first storage unit 1031.

[0082] The data terminals of the first storage unit 1031 are respectively connected to the second communication terminals of the processing unit 102.

[0083] In one embodiment, the first storage unit 1031 is at least used to store data written by the external device through the connection interface 101 and the processing unit 102, as well as atomization data detected by the processing unit 102 when the atomization module 104 is working.

[0084] In addition, the first storage unit 1031 can also be used to store firmware information required for the operation of components such as the processing unit 102 and / or the atomization module 104 in the atomization circuit 100. This application embodiment does not limit this.

[0085] Furthermore, the first storage unit 1031 can also be used, under the control of the processing unit 102, to transmit any possible external data stored internally to the processing unit 102. This application embodiment does not limit this aspect.

[0086] It is worth noting that this allows the storage circuit 100 to store the firmware of each component, the atomization data, and the data written by the external device. Furthermore, since only one first storage unit 1031 is set up, the cost can be reduced.

[0087] In one possible implementation, see [link to relevant documentation]. Figure 3 The storage module 103 includes a second storage unit 1032 and a third storage unit 1033.

[0088] The data terminals of the second storage unit 1032 and the third storage unit 1033 are respectively connected to the corresponding second communication terminals of the processing unit 102.

[0089] In one embodiment, the second storage unit 1032 is used to store data written by the external device through the connection interface 101 and the processing unit 102. The second storage unit 1032 can also be used to transfer the data stored inside the second storage unit 1032 to the processing unit 102 under the control of the processing unit 102.

[0090] In one embodiment, the third storage unit 1033 is used to store the atomization data detected by the processing unit 102 when the atomization module 104 is working.

[0091] Furthermore, the third storage unit 1033 can also be used to store firmware information required for the operation of components such as the processing unit 102 and / or the atomizing module 104 in the atomizing circuit 100. The third storage unit 1033 can also be used to transmit the data stored inside the third storage unit 1033 to the processing unit 102 under the control of the processing unit 102.

[0092] In one possible approach, the external device can also write the data needed for firmware upgrade to the third storage unit 1033 through the connection interface 101 and the processing unit 102, and erase the original firmware data, thereby realizing firmware upgrade of the corresponding components in the circuit 100.

[0093] It is worth noting that when there are multiple storage units in the storage module 103, different access addresses can be assigned to each storage unit so that the processing unit 102 can accurately access the corresponding storage unit and thus ensure that the corresponding data can be processed correctly.

[0094] It is worth noting that in this embodiment, by providing a second storage unit 1032 and a third storage unit 1033 in the atomizing circuit 100, the data written by the external device is stored in the second storage unit 1032, and the data needed or generated internally by the circuit 100 is stored in the third storage unit 1033. This achieves isolation between different data types, thereby improving the security and reliability of data storage.

[0095] In one possible implementation, see [link to relevant documentation]. Figure 4 The atomization module 104 includes: a trigger unit 1041, a switch unit 1042, and an atomization unit 1043.

[0096] The output terminal of the trigger unit 1041 is connected to the first control terminal of the processing unit 102.

[0097] The input terminal of the switching unit 1042 is connected to the second control terminal of the processing unit 102, and the output terminal of the switching unit 1042 is connected to the atomizing unit 1043.

[0098] In one embodiment, the triggering unit 1041 is used to output the level signal to the processing unit 102, specifically, the level signal can be output to the processing unit 102 when certain conditions are met.

[0099] For example, the triggering unit 1041 can be any possible device such as a touch switch, pressure sensor or airflow sensor, and the embodiments of this application do not limit it.

[0100] For example, if the trigger unit 1041 is a touch switch, the level signal can be output when the user triggers the touch switch to close it. If the trigger unit 1041 is a pressure sensor, the level signal can be output when the user triggers the pressure sensor or when the pressure detected by the pressure sensor exceeds a preset pressure value. If the trigger unit 1041 is an airflow sensor, the level signal can be output when the user triggers the airflow sensor or when the airflow sensor detects a gas flow rate exceeding a preset threshold. This application does not limit the scope of the embodiments.

[0101] Generally, the level signal can be a high-level active signal. That is, if the signal output by the trigger unit 1041 is low in the default state, the processing unit 102 will not be triggered to output the PWM signal. Alternatively, the level signal can be set to a low-level active signal according to actual needs, and this application embodiment does not limit this.

[0102] In one embodiment, the switching unit 1042 is used to output a working voltage to the atomizing unit 1043 under the action of the PWM signal.

[0103] The operating voltage can be provided by any possible power source. This application does not limit this.

[0104] In one embodiment, the atomizing unit 1043 is configured to power on or atomize upon receiving the operating voltage. Specifically, the atomizing unit 1043 may be configured to generate heat upon receiving the operating voltage.

[0105] The atomizing unit 1043 may include a heating resistance wire, a sound wave output device, a pressurizing device, and other devices capable of converting the atomized liquid into a gas. In this embodiment, the atomization of the liquid into a gas is described using methods such as heating, pressurizing, and sound waves, and does not imply that the atomizing module 104 provided in this application embodiment can only achieve the purpose of atomization in these ways. This application embodiment does not limit this.

[0106] It is worth noting that when the atomizing unit 1043 receives the operating voltage, the atomizing unit 1043 can atomize the atomizing liquid into gas by outputting heat to the corresponding atomizing liquid, pressurizing the atomizing liquid, or outputting sound waves to the atomizing liquid.

[0107] In one possible implementation, see [link to relevant documentation]. Figure 5 The trigger unit 1041 includes: an airflow sensor MIC and an analog-to-digital converter ADC.

[0108] The first terminal of the airflow sensor MIC is grounded, and the second terminal of the airflow sensor MIC is connected to the input terminal of the analog-to-digital converter (ADC).

[0109] The power supply terminal of the analog-to-digital converter (ADC) is used to input the operating voltage, and the first output terminal of the ADC is connected to the first control terminal of the processing unit 102.

[0110] In one embodiment, the airflow sensor MIC is used to output an analog signal to the analog-to-digital converter (ADC) based on the gas flow rate.

[0111] For example, the gas flow rate can specifically refer to the flow rate of the gas flowing through the airflow sensor MIC. That is, the airflow sensor MIC can output the analog signal when the gas flow rate is greater than a preset threshold, or it can output the analog signal when it is determined that atomization needs to be performed based on the gas flow rate. This application embodiment does not limit this.

[0112] Generally, the higher the gas flow rate, the faster the atomization rate is required. In this case, the required atomization rate can be indicated by the analog signal.

[0113] In one embodiment, the analog-to-digital converter (ADC) is used to convert the analog signal into the level signal and output the level signal to the processing unit 102.

[0114] in addition, Figure 5 The VIN terminal shown is used to power the analog-to-digital converter (ADC), capacitor C0 can be used for filtering, V+1 terminal is used to output the level signal, resistor Ra can be used for stabilization circuit, and component Z1 is a metal cover.

[0115] It is worth noting that the level signal is obtained based on the analog signal conversion. Therefore, the level signal can also indicate the current required atomization speed. After the processing unit 102 receives the level signal, it can adjust the duty cycle of the PWM signal according to the level signal to adjust the atomization rate.

[0116] In one possible implementation, see [link to previous section] Figure 5 The trigger unit 1041 also includes a first light-emitting diode D1.

[0117] The positive terminal of the first light-emitting diode D1 is connected to the second output terminal of the analog-to-digital converter (ADC), and the negative terminal of the first light-emitting diode D1 is grounded.

[0118] In one embodiment, the analog-to-digital converter (ADC) is further configured to supply power to the first light-emitting diode (LED) D1 upon receiving the analog signal, so as to output a prompt message. Specifically, a corresponding voltage may be output to the first LED D1, but this embodiment of the application does not limit this.

[0119] In one embodiment, the prompt message is a light signal generated when the first light-emitting diode D1 emits light. Specifically, the prompt message can be used to indicate that the airflow sensor MIC is outputting an analog signal to the analog-to-digital converter ADC, that the trigger unit 1041 and / or the atomization module 104 is currently powered on, and that the atomization circuit 100 is currently atomizing, etc. This application embodiment does not limit the scope of the prompt message.

[0120] Additionally, see also Figure 5 , Figure 5The diagram also shows a resistor Rb connected between the positive terminal of the first light-emitting diode D1 and the second output terminal of the analog-to-digital converter (ADC). The resistor Rb can limit current and protect the first light-emitting diode D1 from being damaged.

[0121] It is worth noting that because this analog signal is only output during atomization, when the analog-to-digital converter (ADC) supplies power to the first LED D1, causing it to light up, it accurately indicates that atomization is currently in progress. This provides effective assistance to the user, thus enhancing the usability of circuit 100.

[0122] In one possible implementation, see [link to relevant documentation]. Figure 6 The switching unit 1042 includes at least: a first switching transistor M1, a second switching transistor M2, and a first resistor R1.

[0123] The gate of the first switching transistor M1 is connected to the second control terminal of the processing unit 102, the source of the first switching transistor M1 is grounded, and the drain of the first switching transistor M1 is connected to the first terminal of the first resistor R1 and the gate of the second switching transistor M2, respectively.

[0124] The source of the second switch M2 is connected to the second terminal of the first resistor R1, the drain of the second switch M2 is connected to the atomizing unit 1043, and the source of the second switch M2 is used to input the working voltage.

[0125] In one embodiment, the first switch M1 is turned on under the action of the PWM signal. The first switch M1 can be an N-channel switch, such as an NMOS transistor.

[0126] Specifically, since the drain of the first switching transistor M1 receives the operating voltage through the first resistor R1 ( Figure 6 The source of the first switching transistor M1 is grounded (VCC in the signal), so when the PWM signal is high, the gate of the first switching transistor M1 is also high. At this time, the conduction condition of the first switching transistor M1 is met, thus making the first switching transistor M1 conduct.

[0127] In one embodiment, the second switch M2 is used to turn on when the first switch M1 is turned on, so as to output the operating voltage to the atomizing unit 1043. The second switch M2 can be a P-channel switch, such as a PMOS transistor.

[0128] Specifically, since the operating voltage is directly input to the source of the second switch M2 and to its gate through the first resistor R1, when the first switch M1 is off, the source and gate voltages of the second switch M2 do not meet the turn-on condition, and therefore the second switch M2 is off. When the first switch M1 is on, the operating voltage is applied to the gate of the second switch only after passing through the voltage drop across the first resistor R1. At this time, the source and gate voltages of the second switch M2 meet the turn-on condition, and therefore the second switch M2 is on.

[0129] Additionally, see also Figure 6 The switching unit 1042 also includes resistors R2 and R3, and terminal A1 between resistors R2 and R3 can be used to detect whether the atomizing unit 1043 is short-circuited or open-circuited. If the atomizing unit 1043 is a resistance wire, the resistance value of the resistance wire can also be detected. Specifically, terminal A1 can be connected to a detection terminal corresponding to the processing unit 102, but this embodiment does not limit this.

[0130] It is worth noting that when the second switch M2 is turned on, the operating voltage can be output to the atomizing unit 1043 through the second switch M2 and port SWC2, thereby achieving the purpose of powering the atomizing unit 1043.

[0131] In one possible implementation, see [link to relevant documentation]. Figure 7 and Figure 8 The atomizing circuit 100 also includes a power supply module 105.

[0132] The power input terminal of the power supply module 105 is connected to the power output terminal of the connection interface 101, the first output terminal of the power supply module 105 is connected to the power terminal of the processing unit 102, and the second output terminal of the power supply module 105 is connected to the power terminals of the storage module 103 and the atomization module 104, respectively.

[0133] In one embodiment, the power supply module 105 provides operating voltage to the processing unit 102, the storage module 103, and the atomization module 104, and charges them when the connection interface 101 outputs power. In one embodiment, the operating voltage output by the power supply module 105 to the processing unit 102, the storage module 103, and the atomization module 104 can be the same or different. Specifically, it can be adjusted according to the actual voltage required by each unit or module; this embodiment does not limit this.

[0134] It is understood that the power output of the connection interface 101 specifically refers to the external device outputting power to the power supply module 105 through the connection interface 101. In this case, the power supply module 105 can be charged, thus avoiding the need for frequent battery replacements in the atomizing circuit 100 and improving the convenience of recharging the atomizing circuit 100.

[0135] In one possible implementation, see [link to relevant documentation]. Figure 9 The power supply module 105 includes at least: a fuse F1, a charging management unit U, and an energy storage unit BAT.

[0136] The first end of the fuse F is connected to the power output terminal of the connection interface 101, and the second end of the fuse F is connected to the input terminal of the charging management unit U.

[0137] The output of the charging management unit U is connected to the input of the energy storage unit BAT.

[0138] In one embodiment, the fuse F is used to disconnect when the current flowing through the fuse F exceeds a preset current value. This provides overcurrent protection for circuit 100.

[0139] In one embodiment, the charging management unit U may be a charging management chip. The charging management unit U is used to adjust the charging energy input from the connection interface 101 and output the adjusted charging energy to the energy storage unit BAT.

[0140] The charging energy can refer to the electrical energy input to the circuit 100 by the external device through the connection interface 101.

[0141] Specifically, the charging management unit U can be used to adjust any possible parameters such as the voltage, current, and power of the charging energy. Specifically, it can be adjusted according to the parameters of the energy storage unit BAT or the battery cells in the energy storage unit BAT. This application embodiment does not limit this.

[0142] In one embodiment, the energy storage unit BAT includes at least one battery cell.

[0143] In one possible way, see [link / reference] Figure 9 The circuit 100 may also include resistors R4 and R5. One end of resistor R4 and one end of resistor R5 are respectively connected to the corresponding ports of the connection interface 101 through connectors. The other end (USB+) of resistor R4 and the other end (USB-) of resistor R5 are connected to the two first communication terminals of the processing unit 102 to realize the interaction between the circuit 100 and external devices.

[0144] In one possible way, see [link / reference] Figure 9The power supply module 105 may also include a resistor Rd and a second light-emitting diode D2. The negative terminal of the second light-emitting diode D2 may also be connected to the indicator terminal of the charging management unit U, and the terminal A2 connected to the negative terminal of the second light-emitting diode D2 may also be connected to a detection terminal of the processing unit 102.

[0145] Specifically, when the charging management unit U charges the energy storage unit BAT, a voltage is simultaneously applied to the positive terminal of the second light-emitting diode D2. Furthermore, as the charging voltage and / or charging current change, when the charging management unit U determines that the energy storage unit BAT is fully charged, it can adjust the voltage at the indicator terminal to change the light emission state of the second light-emitting diode D2, thereby indicating that the energy storage unit BAT is fully charged.

[0146] In addition, if the processing unit 102 determines that the current energy storage unit BAT is fully charged through other means, the processing unit 102 can adjust the negative voltage of the second light-emitting diode D2 through terminal A2, so that the light-emitting state of the second light-emitting diode D2 changes.

[0147] As can be seen, the above methods can provide users with effective prompts and assistance.

[0148] In one possible way, see [link / reference] Figure 9 The power supply module 105 also includes capacitor C2, resistor Re, resistor Rg, and resistor Rh.

[0149] Capacitor C2 and resistor Re stabilize the circuit. Terminal A3 between resistors Rg and Rh can be connected to processing unit 102 because a certain voltage will exist at terminal A3 when connection interface 101 is connected to the external device. At this time, processing unit 102 can know that connection interface 101 is connected to the external device, thus realizing the connection detection function.

[0150] In one possible way, see [link / reference] Figure 9 The power supply module 105 also includes a resistor Ri. One end of the resistor Ri is connected to the enable terminal of the charging management unit U, and the other end of the resistor Ri is grounded. The enable terminal of the charging management unit U can also be connected to a control terminal of the processing unit 102.

[0151] Specifically, the processing unit 102 can control the charging management unit to start enabling by outputting a corresponding signal to the enabling terminal, or it can control the charging management unit U to adjust the parameters of the charging energy in a certain way. This application embodiment does not limit this.

[0152] In one possible way, see [link / reference] Figure 9The power supply module 105 also includes resistors Rj and Rk. Terminal A5 between resistors Rj and Rk can be connected to a detection terminal of the processing unit 102, allowing the processing unit 102 to detect the cell voltage of the energy storage unit BAT via terminal A5 and the corresponding detection terminal. In other words, voltage detection of the energy storage unit can be achieved.

[0153] In one possible way, see [link / reference] Figure 9 The power supply module 105 also includes a capacitor C1. The first plate of the capacitor C1 is connected to the energy storage unit BAT and the resistor Rk respectively, and the second plate is connected to the ground terminal of the charging management unit U to achieve the function of filtering and stabilizing the circuit.
