[0064] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship or movement of the components in a specific orientation (as shown in the accompanying drawings). If the specific orientation changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0066] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0067] Please see Figure 1 An atomizer 100 provided in this application embodiment includes: a first battery cell 10 for providing power; a first interface 20 for connecting to a power supply, thereby realizing an electrical connection between the atomizer 100 and the power supply; a first USB interface circuit 30 for electrically connecting to a charging device, thereby charging the first battery cell 10 through the charging device; wherein, a first charging path 10a is established between the first interface 20 and the first battery cell 10, and a second charging path 10b is established between the first USB interface circuit 30 and the first battery cell 10; a first control circuit 40 is configured to conduct the first charging path 10a and / or the second charging path 10b, thereby charging the first battery cell 10.

[0068] For example, the first interface 20 may include a pogo pin or other connector capable of transmitting current and communication signals. The first USB interface circuit 30 may include a USB interface or other interface capable of connecting and communicating with external devices. In this embodiment, the external device refers to a device with charging function, such as a charger, power bank, or smart device.

[0069] By providing a first interface 20 that can connect to a power supply, the atomizer 100 can be charged by a power supply; by providing a first USB interface circuit 30 that can be electrically connected to a charging device, the atomizer 100 can be charged by a charging device. Specifically, the first control circuit 40 is configured to: activate the first charging path 10a to charge the first battery cell 10; activate the second charging path 10b to charge the first battery cell 10; and activate both the first charging path 10a and the second charging path 10b to charge the first battery cell 10. Therefore, the atomizer 100 has at least two charging methods. The first charging path 10a and the second charging path 10b are isolated from each other and controlled independently, thus, each charging method is independent of the others and does not affect the others.

[0070] In some embodiments, please refer to Figure 2 The atomizer 100 also includes a unidirectional conduction circuit 50, which is electrically connected between the first interface 20 and the first USB interface circuit 30. The unidirectional conduction circuit 50 is configured to trigger the conduction of the second charging path 10b when the first charging path 10a is turned on, thereby realizing the superposition of the charging current of the first charging path 10a and the second charging path 10b to charge the first battery cell 10.

[0071] like Figure 4 As shown, the unidirectional conduction circuit 50 includes a diode D1. The anode of diode D1 is electrically connected to the power supply electrode VOUT of the first interface 20, and the cathode of diode D1 is electrically connected to the VBUS pin (which is electrically connected to...). Figure 6 The VBUS pin of the USB interface J1 and Figure 7 The VBUS pin of the second charging circuit 70, i.e. the cathode of diode D1, is electrically connected to the first USB interface circuit 30 and the second charging circuit 70 respectively.

[0072] When the first charging path 10a is turned on, diode D1 is turned on, triggering the second charging path 10b to be turned on, thereby realizing the superposition of the charging current of the first charging path 10a and the second charging path 10b to charge the first battery cell 10.

[0073] That is, when using a power supply for charging, a high current is used for charging.

[0074] Please see Figures 2 to 8The first charging path 10a is provided with a first charging circuit 60, including a first charging chip 61, and the first charging circuit 60 is also electrically connected to the first control circuit 40; the second charging path 10b is provided with a second charging circuit 70, including a second charging chip 71, and the second charging circuit 70 is also electrically connected to the first control circuit 40.

[0075] It should be noted that the first charging chip 61 has an isolation function to prevent current from flowing back to the first interface 20 when charging is performed using a charging device (by connecting the second charging path 10b to charge the first battery cell 10), which would cause the first interface 20 to become energized.

[0076] Please continue reading. Figure 3 The first charging circuit 60 also includes a first input detection circuit 62, which is electrically connected to the first interface 20, the first charging chip 61 and the first control circuit 40 respectively. The first control circuit 40 is also configured to control the start or stop of the first charging chip 61 in response to the first detection voltage output by the first input detection circuit 62 and the communication signal received from the power supply.

[0077] like Figure 4 As shown, the first interface 20 includes a power supply electrode VOUT, a communication electrode X1, and a ground electrode GND. Figure 8 As shown, the first control circuit 40 includes a control chip U3 and its peripheral circuits, including a filter circuit composed of resistor R17 and capacitor C5, which is used to filter the output voltage of the first battery cell 10 and then input it to the VCC pin of the control chip U3 to provide power to the control chip U3.

[0078] In some embodiments, the atomizer 100 further includes a signal detection circuit 101 electrically connected between the first interface 20 and the first control circuit 40, the signal detection circuit 101 being configured to detect communication signals transmitted by the power supply.

[0079] The first charging circuit 60 is electrically connected between the power supply electrode VOUT and the VBAT pin (i.e., the first battery cell 10), and is also electrically connected to the control chip U3 and the diode D1. The signal detection circuit 101 is electrically connected between the communication electrode X1 and the control chip U3.

[0080] In some specific embodiments, the first charging chip 61 includes a charging chip U1, which includes at least a VCC pin, an EN pin, a BAT pin, and an ILIM pin. The first input detection circuit 62 includes resistors R1 and R2 and a capacitor C1. Resistors R1 and R2 are connected in series between the power supply electrode VOUT and the ground terminal. The connection node between resistors R1 and R2 is electrically connected to the POG CHECK pin of the control chip U3. The capacitor C1 is connected in parallel between the power supply electrode VOUT and the ground terminal. In some embodiments, the capacitor C1 may be omitted. The VCC pin is electrically connected to the power supply electrode VOUT, the EN pin is electrically connected to the POG EN pin of the control chip U3, and a resistor R3 is provided between the EN pin and the ground terminal. The BAT pin is electrically connected to the VBAT pin (i.e., the first battery cell 10), and a capacitor C2 is provided between the BAT pin and the ground terminal to filter the charging voltage output by the charging chip U1. A resistor R4 is provided between the ILIM pin and the ground terminal to set the charging current output by the charging chip U1, which is a fixed current. In some other embodiments, the charging current output by the charging chip U1 can also be an adjustable current.

[0081] The signal detection circuit 101 includes resistors R5 and R6 (or Figure 12 Resistors R22 and R23 are shown. Resistor R5 is electrically connected between the communication electrode X1 and the POG SIG pin of the control chip U3. One end of resistor R6 is electrically connected to both resistor R5 and the POG SIG pin of the control chip U3, and the other end of resistor R6 is grounded.

[0082] When the first interface 20 is connected to the power supply, the output voltage provided by the power supply reaches the first charging circuit 60 through the power electrode VOUT. Resistors R1 and R2 divide the output voltage to obtain the first detection voltage, which is then transmitted to the POG CHECK pin of the control chip U3. Simultaneously, the communication signal (e.g., a high-level signal) transmitted by the power supply reaches the signal detection circuit 101 through the communication electrode X1. Resistors R5 and R6 divide the communication signal, which is then transmitted to the POG SIG pin of the control chip U3. Therefore, when the first interface 20 is connected to the power supply, if the control chip U3 simultaneously receives the first detection voltage and the communication signal, the POG EN pin of the control chip U3 outputs an enable signal to the charging chip U1, activating the charging chip U1 and connecting the first charging path 10a. When the charging stop condition is met, the POG EN pin of the control chip U3 outputs an enable signal to the charging chip U1, deactivating the charging chip U1.

[0083] The first control circuit 40 responds to the first detection voltage output by the first input detection circuit 62 and the communication signal received from the power supply to control the start or stop of the first charging chip 61, thereby improving the reliability of charging using the power supply.

[0084] Please continue reading. Figure 5 The second charging circuit 70 also includes:

[0085] The second input detection circuit 72 is electrically connected to the first USB interface circuit 30, the second charging chip 71 and the first control circuit 40 respectively. The first control circuit 40 is also configured to control the start or stop of the second charging chip 71 in response to the second detection voltage output by the second input detection circuit 72.

[0086] The first current regulation circuit 73 is electrically connected to the second charging chip 71 and the first control circuit 40 respectively. The first control circuit 40 is also configured to regulate the magnitude of the charging current output by the second charging chip 71.

[0087] like Figure 6 As shown, the first USB interface circuit 30 includes a USB interface J1 and its peripheral circuitry, including resistors R7 to R10 and diode D4. The specific circuit connection is shown in the figure and will not be described in detail here. Figure 7 As shown, the second charging circuit 70 is electrically connected between the VBUS pin (which is electrically connected to the VBUS pin of the USB interface J1 and the VBUS pin of the cathode of diode D1, respectively) and the VBAT pin (i.e., the first battery cell 10). In some embodiments, the second charging circuit 70 further includes a filter circuit composed of resistor R11 and capacitor C3, used to filter the output voltage of the VBUS pin of the USB interface J1 or the VBUS pin of the cathode of diode D1.

[0088] In some specific embodiments, the second charging chip 71 includes a charging chip U2, which includes at least a VCC pin, an EN pin, a BAT pin, and an ILIM pin. The second input detection circuit 72 includes resistors R12 and R13, which are connected in series between the VBUS pin and ground. The connection node between resistors R12 and R13 is electrically connected to the USB CHECK pin of the control chip U3. Specifically, the VCC pin is electrically connected to the VBUS pin, the EN pin is electrically connected to the CHG EN pin of the control chip U3, and a resistor R14 is provided between the EN pin and ground. The BAT pin is electrically connected to the VBAT pin (i.e., the first battery cell 10), and a capacitor C4 and a diode D5 are connected in parallel between the BAT pin and ground to filter the charging voltage output by the charging chip U2. The ILIM pin is connected to ground through resistor R15 and electrically connected to the CURRENT pin of the control chip U3 through resistor R16 to adjust the charging current output by the charging chip U2, which is an adjustable current. In some other embodiments, the charging current output by the charging chip U2 can also be a fixed current.

[0089] When the first USB interface circuit 30 is electrically connected to the charging device, or when the first interface 20 is connected to the power supply, the VBUS pin of the USB interface J1 or the VBUS pin of the cathode of diode D1 outputs a voltage to the second charging circuit 70. Resistors R12 and R13 are used to divide this output voltage to obtain a second detection voltage, thereby controlling the CHG EN pin of chip U3 to output an enable signal to charging chip U2, starting charging chip U2 and conducting the second charging path 10b. When the charging stop condition is met, the CHG EN pin of control chip U3 outputs an enable signal to charging chip U2, turning off charging chip U2.

[0090] Especially when the charging currents of the first charging path 10a and the second charging path 10b are superimposed to charge the first battery cell 10, the charging current output by the second charging chip 71 can be adjusted by the first control circuit 40, which can reduce the charging current of the first battery cell 10, reduce heat generation, improve safety and the service life of the first battery cell 10.

[0091] It should be noted that when charging is performed using a charging device, due to the presence of the unidirectional conduction circuit 50, the voltage in the second charging path 10b will not reach the first interface 20. That is, when charging is performed using a charging device, the first interface 20 is not energized, thus avoiding the risk of electric shock.

[0092] In other embodiments, please refer to Figure 9 and Figure 10In the atomizer 100, a third charging circuit 80 is provided in both the first charging path 10a and the second charging path 10b, including a third charging chip 81. The third charging circuit 80 is also electrically connected to the first control circuit 40. A first switch circuit 90 is also provided in the first charging path 10a, which is electrically connected to the first interface 20, the third charging circuit 80 and the first control circuit 40 respectively.

[0093] Compared to Figure 2 In the embodiment shown, the atomizer 100 saves one charging chip.

[0094] Please continue reading. Figure 10 The third charging circuit 80 also includes:

[0095] The third input detection circuit 82 is electrically connected to the first switch circuit 90, the first USB interface circuit 30, the third charging chip 81 and the first control circuit 40 respectively. The first control circuit 40 is also configured to control the start or stop of the third charging chip 81 in response to the third detection voltage output by the third input detection circuit 82.

[0096] The second current regulation circuit 83 is electrically connected to the third charging chip 81 and the first control circuit 40 respectively. The first control circuit 40 is also configured to regulate the magnitude of the charging current output by the third charging chip 81.

[0097] In some embodiments, the third charging circuit 80 may employ the exact same circuitry as the second charging circuit 70, with the third input detection circuit 82 and the second current regulation circuit 83 as follows: Figure 7 As shown above, please refer to the relevant content; it will not be repeated here.

[0098] When the first USB interface circuit 30 is electrically connected to the charging device, the VBUS pin of the USB interface J1 outputs a voltage to the third charging circuit 80. The third input detection circuit 82 divides this output voltage to obtain a third detection voltage, thereby controlling the CHGEN pin of the chip U3 to output an enable signal to the third charging chip 81, starting the third charging chip 81 and turning on the second charging path 10b. When the charging stop condition is met, the CHGEN pin of the control chip U3 outputs an enable signal to the third charging chip 81, turning off the third charging chip 81.

[0099] The charging current of the first charging path 10a or the second charging path 10b can be adjusted by the second current adjustment circuit 83.

[0100] Please see Figure 11 The first switching circuit 90 includes:

[0101] The fourth input detection circuit 91 is electrically connected to the first interface 20 and the first control circuit 40 respectively;

[0102] The first switching unit 92 is electrically connected between the first interface 20 and the third charging circuit 80;

[0103] The second switch unit 93 is electrically connected to the first switch unit 92 and the first control circuit 40, respectively.

[0104] The first control circuit 40 is further configured to control the second switching unit 93 to turn on in response to the fourth detection voltage output by the fourth input detection circuit 91 and the communication signal received from the power supply, so as to turn on the first switching unit 92 and thereby turn on the first charging path 10a.

[0105] like Figure 12 As shown, the fourth input detection circuit 91 includes resistors R18 and R19, which are connected in series between the power supply electrode VOUT and the ground terminal. The connection node between resistors R18 and R19 is electrically connected to the POG CHECK pin of the control chip U3. The first switching unit 92 includes a MOSFET Q1 and a resistor R20. The drain of MOSFET Q1 is electrically connected to the power supply electrode VOUT, the source of MOSFET Q1 is electrically connected to the VBUS pin of the USB interface J1, the gate of MOSFET Q1 is electrically connected to the second switching unit 93, and resistor R20 is electrically connected between the source and gate of MOSFET Q1. The second switching unit 93 includes a MOSFET Q2 and a resistor R21. The drain of MOSFET Q2 is electrically connected to the gate of MOSFET Q1, the source of MOSFET Q2 is grounded, the gate of MOSFET Q2 is electrically connected to the POG EN pin of the control chip U3, and resistor R21 is electrically connected between the gate and source of MOSFET Q2.

[0106] When the first interface 20 is connected to the power supply, the output voltage provided by the power supply reaches the first switching circuit 90 through the power supply electrode VOUT. Resistors R18 and R19 are used to divide the output voltage to obtain the fourth detection voltage, thereby controlling the POG EN pin of the control chip U3 to output an enable signal to the gate of MOSFET Q2, turning on MOSFET Q2. At this time, the gate voltage of MOSFET Q1 is pulled to ground, satisfying the conduction condition of MOSFET Q1, and MOSFET Q1 turns on, so the output voltage can be output to the third charging circuit 80. The third input detection circuit 82 is used to divide the output voltage of the first switching circuit 90 to obtain the third detection voltage, thereby controlling the CHG EN pin of the control chip U3 to output an enable signal to the third charging chip 81, starting the third charging chip 81 and turning on the first charging path 10a. When the charging stop condition is met, the CHG EN pin of the control chip U3 outputs an enable signal to the third charging chip 81, turning off the third charging chip 81.
