[0002] Common aerosol generation systems typically include a charging box and an aerosol generation device, which can be installed in the charging box for charging.

[0003] Currently, the charging box of an aerosol generation system includes a charging module to charge its own battery and a discharging module to charge the aerosol generation device. This means that the charging box of the aerosol generation system requires two power modules (i.e., the charging module and the discharging module mentioned above) to meet the charging needs of the charging box and the aerosol generation device, which makes it difficult to reduce the size of the charging box and results in high cost. Utility Model Content

[0004] The purpose of this application is to provide a charging box and its aerosol generation system to solve the problem that the current charging box has two power modules to meet the charging needs of the charging box and the aerosol generation device, which makes it difficult to reduce the size of the charging box and results in high cost.

[0005] In a first aspect, this application provides a charging case, including a charging case controller, a charging case battery, and a charging circuit; the input terminal of the charging circuit is electrically connected to the charging case battery, and the input terminal of the charging circuit is also electrically connected to an external power source; the output terminal of the charging circuit is electrically connected to the charging case battery, and the output terminal of the charging circuit is also electrically connected to an aerosol generating device matched with the charging case; the charging case controller is electrically connected to both the charging case battery and the charging circuit; the charging circuit is configured to activate corresponding charging paths in response to a control signal from the charging case controller; wherein, the charging paths include: a charging path where the external power source charges the charging case battery, a charging path where the external power source charges the aerosol generating device, and a charging path where the charging case battery charges the aerosol generating device.

[0006] The charging box designed above incorporates a charging circuit within it. This circuit can activate different charging paths based on control signals sent by the charging box controller. These charging paths include: an external power source charging the charging box battery, an external power source charging the aerosol generating device, and a charging box battery charging the aerosol generating device. This design allows the charging box to meet the charging needs of both the battery and the aerosol generating device with a single charging module, thereby enabling a reduction in the charging box's size and significantly lowering its cost.

[0007] In an optional embodiment of the first aspect, the charging circuit includes an input switching unit, a charging conversion unit, and an output switching unit; the input terminal of the input switching unit is electrically connected to the charging case battery and is also electrically connected to an external power source; the output terminal of the input switching unit is electrically connected to the input terminal of the charging conversion unit; the output terminal of the charging conversion unit is electrically connected to the input terminal of the output switching unit; the output terminal of the output switching unit is electrically connected to the charging case battery and is also electrically connected to an aerosol generating device; the input switching unit is configured to, in response to a control signal, connect the input terminal of the charging conversion unit to the external power source or connect the input terminal of the charging conversion unit to the charging case battery; the charging conversion unit is configured to convert the received power supply voltage into a target charging voltage; the output switching unit is configured to, in response to a control signal, connect the output terminal of the charging conversion unit to the charging case battery or connect the output terminal of the charging conversion unit to the aerosol generating device.

[0008] In the above-described implementation, this solution sets up a simple input switching unit and an output switching unit, which can realize the switching of charging paths based on different control signals. This makes the charging circuit designed in this solution simple and small in size, thereby not only further reducing the size of the charging box, but also further reducing the cost of the charging box.

[0009] In an optional embodiment of the first aspect, the input switching unit includes a first single-pole triple-throw relay; the first normally open terminal of the first single-pole triple-throw relay is electrically connected to an external power supply, the second normally open terminal of the first single-pole triple-throw relay is electrically connected to the charging box battery, the normally closed terminal of the first single-pole triple-throw relay is grounded, and the common terminal of the first single-pole triple-throw relay is electrically connected to the input terminal of the charging conversion unit; the first single-pole triple-throw relay is configured to control its first normally open terminal to connect with its common terminal in response to a first control signal sent by the charging box controller; the first single-pole triple-throw relay is further configured to control its second normally open terminal to connect with its common terminal in response to a second control signal sent by the charging box controller; the first single-pole triple-throw relay is configured to maintain its normally closed terminal electrically connected with its common terminal when no control signal is received.

[0011] In the above implementation method, this solution uses a single-pole triple-throw relay to switch the charging path, integrating multiple switching paths into one device, reducing the number of external wiring and solder joints, and lowering the probability of failure due to line problems.

[0012] In an optional embodiment of the first aspect, the input switching unit includes a first controllable switch and a second controllable switch; a first terminal of the first controllable switch is electrically connected to an external power source, and a second terminal of the first controllable switch is electrically connected to the input terminal of the charging conversion unit; a first terminal of the second controllable switch is electrically connected to the charging case battery, and a second terminal of the second controllable switch is electrically connected to the input terminal of the charging conversion unit; the first controllable switch is configured to control the input terminal of the charging conversion unit to be connected to the external power source in response to a first control signal sent by the charging case controller; the second controllable switch is configured to control the input terminal of the charging conversion unit to be connected to the charging case battery in response to a second control signal sent by the charging case controller.

[0014] In the above implementation, this solution uses a controllable switching transistor to switch the charging path, thereby improving the response capability of the designed charging circuit through the high-frequency switching capability of the controllable switching transistor, and further reducing the size of the charging box based on the small size of the controllable switching transistor.

[0015] In an alternative embodiment of the first aspect, the charging box further includes an external interface; the input terminal of the charging circuit is electrically connected to the external interface, and the external interface is electrically connected to an external power source.

[0016] In the above-described implementation, this solution provides an external interface on the charging case, thereby enabling the charging case to be compatible with various external power sources, avoiding the inconvenience of relying on a single external power source, and thus improving the charging compatibility of the charging case.

[0018] In the above implementation, this solution identifies the access status of external power through the charging cable insertion detection unit, switches the charging path based on the access status of external power, and detects whether the charging cable is actually inserted and connected through the charging cable insertion detection unit, avoiding "virtual charging" caused by loose interface or poor contact (such as charging cable being half-inserted), thereby improving the charging reliability of the charging box under different charging paths.

[0019] In a second aspect, this application provides an aerosol generation system, including an aerosol generation device and a charging box according to any optional embodiment of the first aspect. The aerosol generation device includes a generation device battery, which is configured to be electrically connected to the output terminal of the charging circuit of the charging box when the aerosol generation device is inserted into the charging box.

[0020] The aerosol generation system designed above includes a charging box as described above. Therefore, the charging circuit of the aerosol generation system can conduct different charging paths based on the control signal sent by the charging box controller. The specific charging paths include: a charging path where the external power supply charges the charging box battery, a charging path where the external power supply charges the aerosol generation device, and a charging path where the charging box battery charges the aerosol generation device. As a result, the aerosol generation system designed in this solution only needs one charging module to meet the charging needs of the charging box battery and the aerosol generation device. This not only reduces the size of the aerosol generation system but also significantly reduces its cost.

[0021] In an optional embodiment of the second aspect, the aerosol generating device further includes an aerosol controller and a reverse current blocking device. The aerosol controller is electrically connected to the generating device battery and the reverse current blocking device, respectively. The reverse current blocking device is disposed between the output terminal of the charging circuit and the generating device battery. The aerosol controller is configured to send a current blocking signal to the reverse current blocking device when the output terminal of the charging circuit is connected to the generating device battery. The current blocking signal is used to control the reverse current blocking device to cut off the reverse current.

[0022] In the above-described embodiments, this solution, by setting a reverse current blocking device between the battery of the generating device and the output terminal of the charging circuit, can prevent current from flowing back from the battery of the generating device into the charging circuit or other circuit components, effectively avoiding circuit abnormalities, protecting equipment safety, and improving charging stability.

[0041] Common aerosol generation systems typically include a charging box and an aerosol generation device, which can be installed in the charging box for charging.

[0042] Currently, the charging box of an aerosol generation system includes a charging module to charge its own battery and a discharging module to charge the aerosol generation device. This means that the charging box of the aerosol generation system requires two power modules to meet the charging needs of the charging box and the aerosol generation device, which makes it difficult to reduce the size of the charging box and results in high cost.

[0043] To address the aforementioned issues, this application designs a charging box and its aerosol generation system. By incorporating a charging circuit within the charging box, the circuit can activate different charging paths based on control / modulation signals sent by the charging box controller. These charging paths include: a charging path where an external power source charges the charging box battery, a charging path where an external power source charges the aerosol generation device, and a charging path where the charging box battery charges the aerosol generation device. This design allows the charging box to meet the charging needs of both the charging box battery and the aerosol generation device with a single charging module, thereby enabling a reduction in the size of the charging box and significantly lowering its cost.

[0044] Based on the above ideas, this application first provides a charging case, such as... Figure 1 As shown, the charging case includes a charging case controller 10, a charging case battery 20, and a charging circuit 30. The input terminal of the charging circuit 30 is electrically connected to the charging case battery 20, and can also be electrically connected to an external power source A. The output terminal of the charging circuit 30 is electrically connected to the charging case battery 20, and also electrically connected to an aerosol generating device B that matches the charging case. The charging case controller 10 is electrically connected to both the charging case battery 20 and the charging circuit 30. The aerosol generating device B is a device capable of converting liquid or solid substances into tiny particles using energy forms such as high-pressure gas or ultrasound, and then spraying them out to form an aerosol.

[0045] In the charging box designed above, the charging circuit 30 of this solution can activate different charging paths in response to the control signal sent by the charging box controller 10. These charging paths include a charging path in which the external power source A charges the charging box battery 20, a charging path in which the external power source A charges the aerosol generating device B, and a charging path in which the charging box battery 20 charges the aerosol generating device B.

[0046] Specifically, assuming that the charging box designed in this scheme is connected to an external power source A and needs to be charged, in this case, the charging circuit 30 designed in this scheme can respond to the control signal sent by the charging box controller 10 to control the connection between its input terminal and the external power source A, and control the connection between its output terminal and the charging box battery 20, forming a charging path for the external power source A to charge the charging box battery 20, thereby realizing the external power source A to charge the charging box battery 20.

[0047] Alternatively, assuming that the charging box designed in this scheme contains an aerosol generating device B and is connected to an external power supply A, and the aerosol generating device B needs to be charged, in this case, the charging circuit 30 designed in this scheme can also respond to the control signal sent by the charging box controller 10 to control the connection between its input terminal and the external power supply A, and control the connection between its output terminal and the aerosol generating device B, forming a charging path for the external power supply A to charge the aerosol generating device B, thereby realizing the external power supply A to charge the aerosol generating device B;

[0048] Alternatively, assuming that the charging box designed in this scheme contains an aerosol generating device B, and the charging box is not connected to an external power source A, and it is necessary to charge the aerosol generating device B, in this case, the charging circuit 30 designed in this scheme can also respond to the control signal sent by the charging box controller 10 to connect the controller input terminal to the charging box battery 20 and control its output terminal to connect to the aerosol generating device B, forming a charging path for the charging box battery 20 to charge the aerosol generating device B, thereby realizing the charging box to charge the aerosol generating device B.

[0049] It should be noted that during the formation of the different charging paths described above, the charging circuit 30 receives different control signals sent by the charging box controller 10, thereby enabling differentiated control of the different charging paths.

[0050] The charging box designed above incorporates a charging circuit within it. This circuit can activate different charging paths based on control signals sent by the charging box controller. These charging paths include: an external power source charging the charging box battery, an external power source charging the aerosol generating device, and a charging box battery charging the aerosol generating device. This design allows the charging box to meet the charging needs of both the battery and the aerosol generating device with a single charging module, thereby enabling a reduction in the charging box's size and significantly lowering its cost.

[0051] In an optional implementation of this embodiment, as one possible implementation, such as Figure 2As shown, the charging circuit 30 designed in this scheme may include an input switching unit 310, a charging conversion unit 320, and an output switching unit 330. The input terminal of the input switching unit 310 is electrically connected to the charging box battery 20, and the input terminal of the input switching unit 310 is also used to electrically connect to an external power source A. The output terminal of the input switching unit 310 is electrically connected to the input terminal of the charging conversion unit 320, the output terminal of the charging conversion unit 320 is electrically connected to the input terminal of the output switching unit 330, the output terminal of the output switching unit 330 is electrically connected to the charging box battery 20, and the output terminal of the output switching unit 330 is also used to electrically connect to an aerosol generating device B. The input switching unit 310, the charging conversion unit 320, and the output switching unit 330 are all electrically connected to the charging box controller 10.

[0052] The charging circuit 30 designed above allows the charging box controller 10 to transmit control signals to the input switching unit 310 and the output switching unit 330. In response to the control signal, the input switching unit 310 connects the input terminal of the charging conversion unit 320 to the external power supply A, or connects the input terminal of the charging conversion unit 320 to the charging box battery 20. Similarly, in response to the control signal, the output switching unit 330 connects the output terminal of the charging conversion unit 320 to the charging box battery 20, or connects the output terminal of the charging conversion unit 320 to the aerosol generating device B. The charging conversion unit 320 can convert the received power supply voltage into a target charging voltage. Specifically, it can employ any circuit element that performs voltage conversion, such as a DC-DC converter, a power conversion module, or a charging management chip.

[0053] As a specific example, assuming the charging box designed in this scheme is connected to an external power source A and needs to be charged, in this case, the charging box controller 10 can send a first control signal to the input switching unit 310 and a third control signal to the output switching unit 330. In response to the first control signal, the input switching unit 310 connects the input terminal of the charging conversion unit 320 to the external power source A, and the output switching unit 330 connects the output terminal of the charging conversion unit 320 to the charging box battery 20, thus forming a charging path for the external power source A to charge the charging box battery 20, thereby realizing the charging of the charging box battery 20 by the external power source A.

[0054] As another possible example, suppose the charging box designed in this scheme is connected to an external power source A and needs to charge the aerosol generating device B. In this case, the charging box controller 10 can send a first control signal to the input switching unit 310 and a fourth control signal to the output switching unit 330. In response to the first control signal, the input switching unit 310 connects the input terminal of the charging conversion unit 320 to the external power source A. In response to the fourth control signal, the output switching unit 330 connects the output terminal of the charging conversion unit 320 to the aerosol generating device B, thus forming a charging path for the external power source A to charge the aerosol generating device B, thereby realizing the charging of the aerosol generating device B by the external power source A.

[0055] As another possible example, suppose the charging box designed in this scheme contains an aerosol generating device B, and the charging box is not connected to an external power source A, and it is necessary to charge the aerosol generating device B. In this case, the charging box controller 10 can send a second control signal to the input switching unit 310 and a fourth control signal to the output switching unit 330. In response to the second control signal, the input switching unit 310 connects the input terminal of the charging conversion unit 320 to the charging box battery 20. In response to the fourth control signal, the output switching unit 330 connects the output terminal of the charging conversion unit 320 to the aerosol generating device B, thus forming a charging path for the charging box battery 20 to charge the aerosol generating device B, thereby realizing the charging box battery 20 to charge the aerosol generating device B.

[0056] In the above-described implementation, this solution sets up a simple input switching unit and an output switching unit, which can realize the switching of charging paths based on different control signals. This makes the charging circuit designed in this solution simple and small in size, thereby not only further reducing the size of the charging box, but also further reducing the cost of the charging box.

[0057] In an optional embodiment of this scheme, as one possible implementation, both the input switching unit 310 and the output switching unit 330 can be designed as single-pole three-throw relays. Specifically, for example... Figure 3As shown, the input switching unit 310 includes a first single-pole triple-throw relay K1, and the output switching unit 330 includes a second single-pole triple-throw relay K2. The first normally open terminal K11 of the first single-pole triple-throw relay is electrically connected to an external power source A, the second normally open terminal K12 of the first single-pole triple-throw relay is electrically connected to the charging box battery 20, the normally closed terminal K13 of the first single-pole triple-throw relay is grounded, and the common terminal K14 of the first single-pole triple-throw relay is electrically connected to the input terminal of the charging conversion unit 320. The first normally open terminal K21 of the second single-pole triple-throw relay is electrically connected to the charging box battery 20, the second normally open terminal K22 of the second single-pole triple-throw relay is electrically connected to the aerosol generating device B, the normally closed terminal K23 of the second single-pole triple-throw relay is grounded, and the common terminal K24 of the second single-pole triple-throw relay is electrically connected to the output terminal of the charging conversion unit 320.

[0058] In the charging circuit designed above, the common terminal of both the first single-pole triple-throw relay K1 and the second single-pole triple-throw relay K2 is connected to the normally closed terminal when no control signal is received, thereby disconnecting the charging path. Specifically, the control signal can be a PWM modulation signal, and whether the common terminal is connected to the first normally open terminal or the second normally open terminal can be controlled by different PWM modulation signals.

[0059] As a concrete example, suppose the charging box designed in this scheme is connected to an external power source A and needs to be charged. In this case, the charging box controller 10 can send a first control signal to the first single-pole triple-throw relay K1 and a third control signal to the second single-pole triple-throw relay K2. The first single-pole triple-throw relay K1, in response to the first control signal, generates a magnetic force that applies force to the common terminal K14 of the first single-pole triple-throw relay. This causes the common terminal K14 of the first single-pole triple-throw relay to connect and conduct with the first normally open terminal K11 of the first single-pole triple-throw relay under the applied force, thereby conducting... The connection path between the input terminal of the charging conversion unit 320 and the external power supply A is established; the second single-pole triple-throw relay K2, in response to the energization of the third control signal coil, generates a magnetic force that applies force to the common terminal K24 of the second single-pole triple-throw relay, causing the common terminal K24 of the second single-pole triple-throw relay to connect and conduct with the first normally open terminal K21 of the second single-pole triple-throw relay under the action of the applied force, thereby establishing the connection path between the output terminal of the charging conversion unit 320 and the charging box battery 20, forming a charging path for the external power supply A to charge the charging box battery 20, thereby realizing the charging of the charging box battery 20 by the external power supply A.

[0060] As another possible example, suppose the charging box designed in this scheme is connected to an external power source A and needs to charge the aerosol generating device B. In this case, the charging box controller 10 can send a first control signal to the first single-pole triple-throw relay K1 and a fourth control signal to the second single-pole triple-throw relay K2. The first single-pole triple-throw relay K1, in response to the first control signal, generates a magnetic force through its coil, applying force to the common terminal K14 of the first single-pole triple-throw relay. This causes the common terminal K14 of the first single-pole triple-throw relay to connect and conduct with the first normally open terminal K11 of the first single-pole triple-throw relay under the applied force. The connection path between the input terminal of the charging conversion unit 320 and the external power supply A is established; the second single-pole triple-throw relay K2, in response to the energization of the fourth control signal coil, generates a magnetic force that applies force to the common terminal K24 of the second single-pole triple-throw relay, causing the common terminal K24 of the second single-pole triple-throw relay to connect and conduct with the second normally open terminal K22 of the second single-pole triple-throw relay under the action of the applied force, thereby establishing the connection path between the output terminal of the charging conversion unit 320 and the aerosol generating device B, forming a charging path for the external power supply A to charge the aerosol generating device B, and thus realizing the charging of the aerosol generating device B by the external power supply A.

[0061] As another possible example, suppose the charging box designed in this scheme contains an aerosol generating device B, and the charging box is not connected to an external power source A, and the aerosol generating device B needs to be charged. In this case, the charging box controller 10 can send a second control signal to the first single-pole triple-throw relay K1 and a fourth control signal to the second single-pole triple-throw relay K2. The first single-pole triple-throw relay K1, in response to the second control signal, generates a magnetic force that applies force to the common terminal K14 of the first single-pole triple-throw relay, causing the common terminal K14 of the first single-pole triple-throw relay to connect with the second normally open terminal K12 of the first single-pole triple-throw relay under the applied force. The circuit is turned on, thus connecting the input terminal of the charging conversion unit 320 with the charging box battery 20. The second single-pole triple-throw relay K2 responds to the energization of the fourth control signal coil to generate a magnetic force that applies force to the common terminal K24 of the second single-pole triple-throw relay. Under the action of the force, the common terminal K24 of the second single-pole triple-throw relay is connected and turned on with the second normally open terminal K22 of the second single-pole triple-throw relay, thereby connecting the output terminal of the charging conversion unit 320 with the aerosol generating device B, forming a charging path for the charging box battery 20 to charge the aerosol generating device B, thereby realizing the charging box battery 20 to charge the aerosol generating device B.

[0062] In the above implementation method, this solution uses a single-pole triple-throw relay to switch the charging path, integrating multiple switching paths into one device, reducing the number of external wiring and solder joints, and lowering the probability of failure due to line problems.

[0063] In an optional embodiment of this invention, the input switching unit 310 and the output switching unit 330 may also be in the form of controllable switching transistors, as one possible implementation, such as... Figure 4 As shown, the input switching unit 310 includes a first controllable switch K3 and a second controllable switch K4, and the output switching unit 330 includes a third controllable switch K5 and a fourth controllable switch K6. The first terminal of the first controllable switch K3 is electrically connected to an external power supply A, and the second terminal of the first controllable switch K3 is electrically connected to the input terminal of the charging conversion unit 320. The first terminal of the second controllable switch K4 is electrically connected to the charging box battery 20, and the second terminal of the second controllable switch K4 is also electrically connected to the input terminal of the charging conversion unit 320. The first terminal of the third controllable switch K5 is electrically connected to the output terminal of the charging conversion unit 320, and the second terminal of the fourth controllable switch K6 is electrically connected to the output terminal of the charging conversion unit 320. The second terminal of the fourth controllable switch K6 is also electrically connected to the aerosol generating device B. Specifically, the controllable switches can be field-effect transistors, IGBTs, or MOSFETs.

[0064] The charging circuit 30 designed above serves as a specific example. Assuming that the charging box designed in this scheme is connected to an external power source A and needs to charge the charging box itself, in this case, the charging box controller 10 can send a first control signal to the first controllable switch K3 and a third control signal to the third controllable switch K5. The first controllable switch K3 closes in response to the first control signal, thereby connecting the input terminal of the charging conversion unit 320 to the external power source A. The third controllable switch K5 closes in response to the third control signal, thereby connecting the output terminal of the charging conversion unit 320 to the charging box battery 20, forming a charging path for the external power source A to charge the charging box battery 20, thereby realizing the charging of the charging box battery 20 by the external power source A.

[0065] As another possible example, suppose the charging box designed in this scheme is connected to an external power source A and needs to charge the aerosol generating device B. In this case, the charging box controller 10 can send a first control signal to the first controllable switch K3 and a fourth control signal to the fourth controllable switch K6. The first controllable switch K3 closes in response to the first control signal, thereby connecting the input terminal of the charging conversion unit 320 to the external power source A. The fourth controllable switch K6 closes in response to the fourth control signal, thereby connecting the output terminal of the charging conversion unit 320 to the aerosol generating device B, forming a charging path for the external power source A to charge the aerosol generating device B, thereby realizing the charging of the aerosol generating device B by the external power source A.

[0066] As another possible example, suppose the charging box designed in this scheme contains an aerosol generating device B, and the charging box is not connected to an external power source A, and it needs to charge the aerosol generating device B. In this case, the charging box controller 10 can send a second control signal to the second controllable switch K4 and a fourth control signal to the fourth controllable switch K6. The second controllable switch K4 responds to the second control signal and its coil closes, thereby connecting the input terminal of the charging conversion unit 320 to the charging box battery 20. The fourth controllable switch K6 responds to the fourth control signal and closes, thereby connecting the output terminal of the charging conversion unit 320 to the aerosol generating device B, forming a charging path for the charging box battery 20 to charge the aerosol generating device B, thereby realizing the charging box battery 20 to charge the aerosol generating device B.

[0067] In the above implementation, this solution uses a controllable switching transistor to switch the charging path, thereby improving the response capability of the designed charging circuit through the high-frequency switching capability of the controllable switching transistor, and further reducing the size of the charging box based on the small size of the controllable switching transistor.

[0068] In an optional embodiment of this design, the charging box can also utilize an external interface 40. The input terminal of the charging circuit 30 is electrically connected to the external interface 40. Specifically, as shown below... Figure 5 As shown, the input terminal of the input switching unit 310 in the charging circuit 30 is electrically connected to the external interface 40. The external interface 40 can be electrically connected to an external power supply A, thereby transmitting the electrical signal of the external power supply A to the input switching unit 310. Specifically, the external interface 40 can be any one or more of the following: USB interface, Type-C interface, Lightning interface, and USB-C interface.

[0069] In the above-described implementation, this solution provides an external interface on the charging case, thereby enabling the charging case to be compatible with various external power sources, avoiding the inconvenience of relying on a single external power source, and thus improving the charging compatibility of the charging case.

[0070] In an optional implementation of this embodiment, based on the design of the external interface 40, such as Figure 5 As shown, the charging box designed in this scheme may also include a charging cable insertion detection unit 50. The charging cable insertion detection unit 50 is electrically connected to the external interface 40 and the charging box controller 10 respectively. When an external power source A is inserted into the external interface 40, the charging cable insertion detection unit 50 can send a power insertion signal to the charging box controller, so that the charging box controller 10 can sense the access of the external power source A and thus realize subsequent charging path control.

[0071] Specifically, as one possible implementation, for example, when the charging case controller 10 detects that an external power source A is connected to the external interface 40 based on the charging cable insertion detection unit 50, and detects that the charging case battery 20 has a low power level, the charging case controller 10 can send a first control signal to the input switching unit 310 and a third control signal to the output switching unit 330, so that the input terminal of the input switching unit 310 is connected to the external interface 40, and the output terminal of the output switching unit 330 is connected to the charging case battery 20, thereby enabling the external power source A to charge the charging case battery 20; as another example, when the charging case controller 10 detects that an external power source A is connected to the external interface 40 based on the charging cable insertion detection unit 50, and detects that the aerosol generating device B has a low power level, the charging case controller 10 can send a first control signal to the input switching unit 310. The control signal and the fourth control signal are sent to the output switching unit 330, so that the input terminal of the input switching unit 310 is connected to the external interface 40 and the output terminal of the output switching unit 330 is connected to the aerosol generating device B, thereby enabling the external power supply A to charge the aerosol generating device B; or, for example, if the charging box controller 10 detects that the external interface 40 is not connected to a power source and the aerosol generating device B has a low power level based on the charging cable insertion detection unit 50, the charging box controller 10 can send a second control signal to the input switching unit 310 and a fourth control signal to the output switching unit 330, so that the input terminal of the input switching unit 310 is connected to the charging box battery 20 and the output terminal of the output switching unit 330 is connected to the aerosol generating device B, thereby enabling the charging box battery 20 to charge the aerosol generating device B.

[0072] In addition, the charging box controller 10 can also detect whether the charging cable is truly inserted and connected through the charging cable insertion detection unit 50, avoiding "virtual charging" caused by loose interfaces or poor contact (such as the charging cable being only partially inserted).

[0073] Specifically, the charging cable insertion detection unit 50 can adopt various existing forms. For example, the charging cable insertion detection unit 50 can be a signal pin detection unit, which uses the level / resistance changes of the power supply pin (VCC), ground pin (GND), or specific detection pin (ID pin) of the external interface 40 itself to determine the insertion status. For example, when the external interface 40 is a USB-C interface, when the USB-C plug is inserted, the CC (Configuration Channel) pin inside the plug will connect with the CC pin of the external interface 40. The charging cable insertion detection unit 50 can determine whether it is inserted by detecting the change in the resistance or voltage signal of the CC pin. In addition, the charging cable insertion detection unit 50 can also be a mechanical contact detection unit, which uses the mechanical spring contacts inside the interface. When the charging cable is inserted, the plug squeezes the spring contacts to make them conduct or disconnect, generating an electrical signal change, thereby determining whether it is inserted based on the electrical signal change.

[0074] In the above implementation, this solution identifies the access status of the external power source through the charging cable insertion detection unit 50, switches the charging path based on the access status of the external power source, and detects whether the charging cable is actually inserted and connected through the charging cable insertion detection unit 50, so as to avoid "virtual charging" caused by loose interface or poor contact (such as charging cable being half-inserted), thereby improving the charging reliability of the charging box under different charging paths.

[0075] This application also provides an aerosol generation system, such as Figure 6 As shown, the aerosol generation system includes a charging box 1 as described in any of the optional embodiments above and an aerosol generation device B. The aerosol generation device B includes a generation device battery B1. When the aerosol generation device B is inserted into the charging box 1, the generation device battery B1 is electrically connected to the output terminal of the charging circuit 30 of the charging box 1. In this way, the charging circuit 30 can be turned on based on the different charging paths described above, so as to realize that the external power supply A charges the generation device battery B1, or the charging box battery 20 charges the generation device battery B1.

[0076] The aerosol generation system designed above includes a charging box as described above. Therefore, the charging circuit of the aerosol generation system can conduct different charging paths based on the control signal sent by the charging box controller. The specific charging paths include: a charging path where the external power supply charges the charging box battery, a charging path where the external power supply charges the aerosol generation device, and a charging path where the charging box battery charges the aerosol generation device. As a result, the aerosol generation system designed in this solution only needs one charging module to meet the charging needs of the charging box battery and the aerosol generation device. This not only reduces the size of the aerosol generation system but also significantly reduces its cost.

[0077] In an optional implementation of this embodiment, such as Figure 7 As shown, the aerosol generating device B also includes an aerosol controller B2 and a reverse current blocking device B3; the aerosol controller B2 is electrically connected to the generating device battery B1 and the reverse current blocking device B3 respectively; the reverse current blocking device B3 is disposed between the output terminal of the charging circuit 30 and the generating device battery B1.

[0078] In the aerosol generation system designed above, when the aerosol controller B2 is connected to the battery B1 of the generation device at the output end of the charging circuit 30, it can send a current blocking signal to the reverse current blocking component B3; the reverse current blocking component B3 cuts off the reverse current based on the current blocking signal, thereby preventing current backflow.

[0079] In the above-described embodiment, by providing a reverse current blocking component B3 between the battery B1 of the generating device and the output terminal of the charging circuit 30, the current can be prevented from flowing back from the battery B1 of the generating device into the charging circuit 30 or other circuit components, which can effectively avoid circuit abnormalities, protect equipment safety and improve charging stability.

[0080] In addition, the aerosol controller B2 designed in this scheme can communicate with the charging box controller 10. For example, the aerosol controller B2 can transmit the power of the generating device battery B1 to the charging box controller 10, so that the charging box controller 10 can sense the power of the generating device battery B1, and then, when the power of the generating device battery B1 is low, prioritize charging the generating device battery B1 by adjusting the charging path of the charging circuit.
