Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to an atomization system and a charging method thereof. Background Art

[0002] Atomizers are electronic devices that simulate smoking to produce aerosols and provide users with the taste and mouthfeel of cigarettes. Atomizers have different flavors while having the taste of real cigarettes, and can reduce the production of harmful substances by 90%, which has won people's favor. Whether it is a traditional atomizer that uses sprays or an emerging heat-not-burn atomizer, atomizers are electronic devices, and most common products are equipped with power components such as lithium batteries. Therefore, matching charging equipment is required to ensure that the atomizer has enough power to generate aerosols from the atomization matrix during use.

[0003] Currently, most of the charging pogo pins designed for the atomizer devices and their matching charging devices on the market are 2 pins (power contact and ground contact). The charging device is always on as a power source, which will cause the power consumption of the atomizer device and the charging device to be relatively large. Therefore, the battery power of the charging device is consumed very quickly, which indirectly shortens the single use time of the atomizer device. In addition, the atomizer device and the charging device cannot communicate with each other, and the battery status of the charging device cannot be obtained in time, resulting in the situation that the atomizer device cannot be charged in time, which brings inconvenience to the user.

The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Figure 1 This is a schematic diagram of the structure of an atomization system provided by an embodiment of the present application. Figure 1 As shown, the atomization system provided in this embodiment includes an atomization device 100 and a charging device 200 .

[0053] The atomization device 100 includes a heating element and an atomizer containing an atomization matrix. When the atomization device 100 is in use, the heating element is controlled to heat, and the atomization matrix in the atomizer generates an aerosol after being heated, providing a user with a sense of use. In the present embodiment, the atomization device 100 also includes a first rechargeable battery 101, a first interface 102, and a second interface 103, wherein the first rechargeable battery 101 provides a working voltage for the atomization device 100, and the heating element is driven to heat by the first rechargeable battery 101. The first interface 102 is used to connect an external power supply, and can obtain voltage through a power supply for charging. In some embodiments, the first interface 102 can be a Micro-USB interface, a Type-C interface, or a wireless charging interface, all of which can be connected to an external power supply and a device, and can realize data transmission and charging.

[0054] The charging device 200 is a convenient device that can charge a mobile device. In some embodiments, the charging device 200 is a charging compartment, which has a charging base and a charging compartment. The charging compartment has multiple charging ports built in, which can charge multiple devices at the same time. The charging device 200 includes at least a second rechargeable battery 201 and a third interface 202, and the third interface 202 is used to connect to the second interface 103 of the atomizing device 100. In some embodiments, the third interface 202 can be a wired interface, such as a USB-C interface, a Micro-USB interface, etc., or a wireless interface, such as an induction interface, or a metal contact interface.

[0055] In this embodiment, the atomization device 100 has three charging states, including a first charging state, a second charging state, and a third charging state. Specifically, the first charging state is when the first interface 102 is connected to an external power source, the first rechargeable battery 101 obtains voltage through the external power source for charging; the second charging state is when the second interface 103 is connected to the third interface 202, the first rechargeable battery 101 obtains voltage through the second rechargeable battery 201 for charging; the third charging state is when the first interface 102 is connected to an external power source and the second interface 103 is connected to the third interface 202 respectively, and when the first rechargeable battery 101 is fully charged, the second rechargeable battery 201 obtains voltage through the external power source for reverse charging.

[0056] It is understandable that, in this embodiment, the charging method of the first rechargeable battery 101 of the atomizing device 100 itself can be to connect the external power supply through the first interface 102 and the necessary data line, adapter, etc. to obtain the voltage for charging. It can also be connected to the third interface 202 of the charging device 200 matched with the second interface 103, and the voltage is obtained by the battery of the charging device 200 to achieve charging. At the same time, the atomizing device 100 can also act as a medium. When the first interface 102 is connected to the external power supply and the second interface 103 is connected to the charging device 200, it will give priority to charging its own first rechargeable battery 101. After being fully charged, it acts as a medium to connect the external power supply and the charging device 200, realizing the charging of the second rechargeable battery 201 by the external power supply, which can be regarded as the reverse charging of the atomizing device 100 to the charging device 200, which can save the step of connecting the external power supply for charging when the charging device 200 is out of power, saving time, improving charging efficiency, and extending the single use cycle of the atomizing device 100.

[0057] Figure 2 This is a schematic diagram of the structure of an atomization system provided in another embodiment of the present application. Figure 2As shown, the atomizing device 100 of this embodiment further includes at least one of a first processor 104 , a switch circuit 105 , and a first charging circuit 106 . The charging device 200 further includes a second processor 203 and a second charging circuit 204 .

[0058] In this embodiment, the output end of the first charging circuit 106 of the atomizing device 100 is connected to the input end of the first rechargeable battery 101, and the output end of the second charging circuit 204 of the charging device 200 is connected to the input end of the second rechargeable battery 201. The first charging circuit 106 of the atomizing device 100 and the second charging circuit 204 of the charging device 200 are connected via a switch circuit 105.

[0059] When the atomizer device 100 is in the first charging state, the first interface 102 of the atomizer device 100 obtains voltage through an external power supply, and transmits the voltage to the first rechargeable battery 101 through the first charging circuit 106, so as to charge the first rechargeable battery 101. When the atomizer device 100 is in the second charging state, the switch circuit 105 is in the on state, the second interface 103 of the atomizer device 100 obtains voltage through the second rechargeable battery 201, and transmits the voltage to the first rechargeable battery 101 through the second charging circuit 204, the switch circuit 105 and the first charging circuit 106 in sequence, so as to charge the first rechargeable battery 101. When the atomizer device 100 is in the third charging state, the first interface 102 of the atomizer device 100 obtains voltage through an external power supply, and transmits the voltage to the second rechargeable battery 201 through the first charging circuit 106, the switch circuit 105 and the second charging circuit 204, so as to reversely charge the second rechargeable battery 201.

[0060] In some embodiments, the first processor 104 of the atomizing device 100 and the second processor 203 of the charging device 200 are communicatively connected via the second interface 103 and the third interface 202 .

[0061] The second interface 103 and the third interface 202 are Pogo Pin or spring pin interfaces, and have 3pins (power contact, communication contact and ground contact). When connected, the respective communication contacts establish a communication channel. In addition, the communication pins of the first processor 104 and the second processor 203 are connected by a single signal line, and the two use a single signal line for data transmission. Its communication structure is simple, and the chip can save the use of I / O port lines, which is particularly important for systems with compact design and limited resources. Compared with multi-line communication, single-line communication is more economical and efficient. Single-line communication not only supports one-way transmission of data, but also supports two-way communication, that is, the first device and the second device can communicate with each other through a single signal line to achieve data interaction and sharing. Although single-line communication uses a single signal line, it still supports high-speed data transmission. For example, the data transmission rate of a single bus is generally 16.3Kbit / s, and the maximum can reach 142Kbit / s, which also meets the demand for data transmission speed. At the same time, it should be noted that a single signal line performs well in bus expansion and maintenance, providing efficient and convenient space for subsequent system expansion and maintenance.

[0062] Figure 3 This is a circuit diagram of an atomization device provided by an embodiment of the present application. Figure 3 As shown, the atomization device 100 of this embodiment includes a first rechargeable battery 101 , a first interface 102 , a second interface 103 , a first processor 104 , a switch circuit 105 and a first charging circuit 106 .

[0063] In this embodiment, the first interface 102 is USB1, and the first processor 104 includes a control chip U2, which has at least a communication pin and a plurality of input and output pins. The first charging circuit 106 includes a resistor R1, a resistor R2, a resistor R3, a voltage stabilizing chip U1, a capacitor C1, a capacitor C2, a resistor R4, a resistor R5, a diode D1, a resistor R6, a capacitor C3, a resistor R7, a battery management chip U3 and a capacitor C4. The switch circuit 105 includes a switch tube Q1, a resistor R10, a resistor R11 and a switch tube Q2. The second interface 103 is an interface J3 including 3 pins, and its communication pin is connected to the control chip U2.

[0064] Specifically, the USB1 interface is connected to the control chip U2 through the resistor R2 for transmitting the connection signal; the resistor R1 and the resistor R3 are connected to the USB1 interface as the peripheral resistors of the USB1 interface. The voltage stabilizing chip U1 is connected to the power output end of the USB1 interface, the capacitor C1 and the capacitor C2 are respectively connected in parallel between the input end and the output end of the voltage stabilizing chip U1 and the ground end, the resistor R4 and the resistor R5 are connected in series and then connected in parallel between the output end and the ground end of the voltage stabilizing chip U1, the diode D1 is connected between the voltage stabilizing chip U1 and the input end of the battery management chip U3, the resistor R6 and the capacitor C3 are connected in series and then connected in parallel between the diode D1 and the input end of the battery management chip U3, and the output end of the battery management chip U3 is connected to the first rechargeable battery 101; the capacitor C4 is connected between the output end and the ground end of the battery management chip U3. One end of the resistor R10 is connected to the control chip U2, and the other end is connected to the control end of the switch tube Q2. The first end of the switch tube Q2 is connected to the control end of the switch tube Q1. The first end of the switch tube Q1 is connected to the input end of the battery management chip U3. The second end of the switch tube Q1 is connected to the voltage pin of the interface J3.

[0065] Figure 4 A circuit diagram of a charging device provided in one embodiment of the present application. Figure 4 As shown, the charging device 200 of this embodiment includes a second rechargeable battery 201 , a third interface 202 , a second processor 203 and a second charging circuit 204 .

[0066] The second processor 203 includes a control chip U2, and the third interface is a communication pin of the interface J1 connected to the control chip U2. The second charging circuit 204 includes capacitors C1, C2, a battery management chip U1, an inductor L1, resistors R4, R5, capacitor C5, resistor R9 and a voltage stabilizing chip U3.

[0067] Specifically, the power pin of the interface J1 is connected to the input end of the second charging circuit 204 , and the capacitor C1 and the capacitor C2 are connected in parallel between the second rechargeable battery 201 and the input end of the second charging circuit 204 .

[0068] During the charging process of the atomizing device 100, when the USB1 of the atomizing device 100 is connected to an external power source, the input voltage is sequentially input to the first rechargeable battery 101 through the voltage regulator chip U1, the diode D1 and the battery management chip U3 to charge it. At this time, the POG0_CTL pin output signal of the control chip U2 of the atomizing device 100 controls the switch tube Q1 to be turned off, and the external power source cannot charge the second rechargeable battery 201.

[0069] When the interface J2 of the atomizing device 100 is connected to the interface J1 of the charging device 200, the control chip communication between the two can be realized through the communication quotes. The POG0_CTL pin output signal of the control chip U2 of the atomizing device 100 controls the switch tube Q1 to turn on, and the second rechargeable battery 201 outputs a voltage of 5V through the battery management chip U3, and charges the first rechargeable battery 101 through the switch tube Q1 and the first charging circuit 106.

[0070] When the USB1 of the atomizing device 100 is connected to an external power source and the interface J2 is also connected to the interface J1 of the charging device 200, the control chip U2 of the atomizing device 100 detects the power of the first rechargeable battery 101. When the power of the first rechargeable battery 101 is not fully charged, a signal is transmitted to the control chip of the charging device 200 through the interface J1 to control its battery management chip U3 to change from a boost mode to a buck mode. At the same time, the control chip U2 of the atomizing device 100 also controls the switch tube Q1 to be cut off. At this time, the input voltage of the external power source is sequentially input to the first rechargeable battery 101 through the voltage regulator chip U1, the diode D1 and the battery management chip U3 to charge it. If it is detected that the power of the first rechargeable battery 101 is fully charged, the CHAG of the control chip U2 of the atomizing device 100 is turned off. The EN pin is pulled low, turning off the battery management chip U3 to charge the first rechargeable battery 101, and at the same time controlling the switch tube Q1 to be turned on, and the input voltage of the external power supply charges the second rechargeable battery 201 through the switch tube Q1, the power supply end of the interface J1, and the battery management chip U1.

[0071] In summary, the atomization system provided by any of the above embodiments includes an atomization device and a charging device that can be matched through an interface connection, the atomization device includes a first rechargeable battery, and the charging device includes a second rechargeable battery; the atomization device has three charging states, wherein the first charging state is that the first rechargeable battery is charged through an external power supply; the second charging state is that when the atomization device is connected to the charging device, the first rechargeable battery is charged through the second rechargeable battery; the third charging state is that when the atomization device is connected to the external power supply and the charging device at the same time, and the first rechargeable battery is fully charged, the second rechargeable battery is reversely charged through the external power supply. The atomization device of this embodiment enables the atomization device to be charged through the charging device when there is no external power supply, and when there is an external power supply, the atomization device charges itself and reversely charges the charging device through the external power supply, thereby extending the single use cycle of the atomization device and the charging device.

[0072] The following describes in detail the logic of the atomization device 100 during the charging process based on the communication between the first processor 104 and the second processor 203 for the atomization system provided in any of the above embodiments.

[0073] In some embodiments, when the second interface 103 is connected to the third interface 202, that is, when the atomizer device 100 is connected to the charging device 200, the first processor 104 of the atomizer device 100 is used to monitor the power level of the first rechargeable battery 101, for example, the voltage of the first rechargeable battery 101 can be monitored through a sampling circuit. When the power level of the first rechargeable battery 101 does not reach the preset first threshold, a first signal indicating that charging is required is output to the second processor 203; when the power level of the first rechargeable battery 101 reaches the preset first threshold, a second signal indicating that charging is not required is output to the second processor 203.

[0074] It is understandable that when the atomization device 100 and the charging device 200 are connected, if the two are charged directly and are in a charging state for a long time, it will cause a series of problems such as increased power consumption and increased temperature of the atomization device 100 and the charging device 200. Therefore, after the second interface 103 is connected to the third interface 202, the first processor 104 of the atomization device 100 determines whether charging is needed based on the monitored power level of the first rechargeable battery 101, and transmits it to the second processor 203 through the communication interface, thereby improving the charging efficiency and saving power consumption.

[0075] Normally, the first rechargeable battery 101 of the atomization device 100 is between 3.7-4.2V. In some embodiments, the preset first threshold value can be 4.1V. When the power of the first rechargeable battery 101 is lower than 4.1V, the first processor 104 outputs a first signal indicating that charging is required to the second processor 203; when the power of the first rechargeable battery 101 is lower than 4.1V, the first processor 104 outputs a second signal indicating that charging is not required to the second processor 203.

[0076] At this time, the second processor 203 is used to respond to the first signal, detect the power level of the second rechargeable battery 201, and when the power level of the second rechargeable battery 201 is greater than or equal to the preset second threshold value, drive the control switch circuit 105 to turn on, and output voltage through the second rechargeable battery 201 to enable the atomization device 100 to enter the second charging state; when the battery power of the charging device 200 is less than the preset second threshold value, output a third signal indicating refusal to charge to the first processor 104, and drive the control switch circuit 105 to turn off; and, in response to the second signal, the control switch circuit 105 is turned off, and the second rechargeable battery 201 stops outputting voltage.

[0077] It is understandable that after receiving the first signal transmitted by the first processor 104, the second processor 203 immediately monitors and obtains the power level of its own second rechargeable battery 201. When the power level of the second rechargeable battery 201 is greater than or equal to the preset second threshold, the first rechargeable battery 101 can be charged. When the power level of the second rechargeable battery 201 is less than the second threshold, some power needs to be retained to maintain its own working state, for example, it needs to maintain communication with the first processor 104, so at this time it needs to refuse to charge the first rechargeable battery 101 and inform the first processor 104.

[0078] In some embodiments, the preset second threshold value may be 3.4V, that is, when the power level of the second rechargeable battery 201 is higher than 3.4V, upon receiving the first signal, the output drive signal drives the control switch circuit 105 to turn on, and charges the first rechargeable battery 101 through the second charging circuit 204 and the first charging circuit 106; when the power level of the second rechargeable battery 201 is lower than 3.4V, upon receiving the first signal, the switch circuit 105 is kept off, and a third signal indicating refusal to charge is output to the first processor 104.

[0079] Furthermore, after the second processor 203 receives the second signal transmitted by the first processor 104, it can be known that the power of the first rechargeable battery 101 has reached the preset first threshold value, and charging is not needed at this time. At this time, the second processor 203 controls the driving signal to keep the switch circuit 105 from turning on, and controls the second rechargeable battery 201 not to output voltage.

[0080] In some embodiments, during the process of the second rechargeable battery 201 charging the first rechargeable battery 101, the first processor 104 is also used to switch the atomization device 100 from the current second charging state to the first charging state when it detects that the first interface 102 is connected to an external power supply, and at the same time output a fourth signal indicating that charging is stopped to the second processor 203.

[0081] In response to the fourth signal, the second processor 203 controls the switch circuit 105 to be turned off and the second rechargeable battery 201 to stop outputting voltage.

[0082] It is understandable that when the second interface 103 is connected to the third interface 202, that is, when the atomizing device 100 is connected to the charging device 200, and the atomizing device 100 is in the second charging state, that is, the process of the second rechargeable battery 201 charging the first rechargeable battery 101, if the first processor 104 detects that the first interface 102 is connected to an external power source, the first processor 104 will control the switching of the charging state, that is, the second rechargeable battery 201 charges the first rechargeable battery 101, and switches to charging the first rechargeable battery 101 from the external power source to save the power of the second rechargeable battery 201. At the same time, the first processor 104 transmits a fourth signal representing the stop of charging to the second processor 203 through the communication interface. When the second processor 203 receives the fourth signal, it controls the switch circuit 105 to be turned off, and the second rechargeable battery 201 stops outputting voltage to the first rechargeable battery 101.

[0083] In some embodiments, after the atomization device 100 switches from the current second charging state to the first charging state, the first processor 104 is further used to control the switch circuit 105 to turn on when it detects that the first rechargeable battery 101 is fully charged, thereby switching the atomization device 100 from the first charging state to the third charging state.

[0084] It can be understood that, during the process of the second rechargeable battery 201 charging the first rechargeable battery 101, the first processor 104 is also used to control the atomization device 100 to switch from the second charging state to the first charging state when it detects that the first interface 102 is connected to the external power supply. At this time, the first processor 104 will continue to monitor and obtain the power of the first rechargeable battery 101. When it is detected that the first rechargeable battery 101 is fully charged, the output signal of the driving control switch circuit 105 is turned on, connecting the first charging circuit 106 and the second charging circuit 204, and controlling the atomization device 100 to switch from the first charging state to the third charging state.

[0085] In some embodiments, the first processor 104 is further configured to output an interrupt signal for determining that the communication with the second processor 203 is interrupted when the second rechargeable battery 201 is not detected to be charging the first rechargeable battery 101 and the third signal is not obtained.

[0086] It can be understood that when the atomization device 100 is connected to the charging device 200, that is, when the second interface 103 is connected to the third interface 202, based on the above embodiment, there may be two situations: one is that the power of the first rechargeable battery 101 does not reach the preset first threshold, and the second processor 203 should respond to the first signal to control the second rechargeable battery 201 to charge the first rechargeable battery 101. At this time, if the first processor 104 does not detect that the second rechargeable battery 201 is charging the first rechargeable battery 101, it may be that the second processor 203 does not obtain the first signal transmitted by the first processor 104; the second is that the power of the second rechargeable battery 201 is lower than the preset second threshold, and the third signal refusing to charge the first rechargeable battery 101 is output through the second processor 203, and the first processor 104 does not obtain the third signal. The above two situations both illustrate that the communication between the first processor 104 and the second processor 203 is interrupted. At this time, the first processor 104 will output an interrupt signal to determine that the communication with the second processor 203 is interrupted.

[0087] There are at least two possible reasons for the interruption of communication between the first processor 104 and the second processor 203: one is that the charging device 200 has power, that is, the second rechargeable battery 201 has power to charge the first rechargeable battery 101, but the communication interface fails, and the second processor 203 does not obtain the first signal transmitted by the first processor 104; the other is that the charging device 200 is in low power or no power, that is, the power of the second rechargeable battery 201 is lower than the preset second threshold, or is in a "dead battery" state, and the second processor 203 cannot transmit the third signal to the first processor 104 through the communication interface. At this time, it is necessary to replenish the power in time to restore the communication between the first processor 104 and the second processor 203.

[0088] In some embodiments, the first processor 104 is further configured to drive the switch circuit 105 to conduct according to an interrupt signal, and control the atomization device 100 to enter a second charging state, or control the atomization device 100 to enter a third charging state when the first interface 102 is connected to an external power supply.

[0089] It can be understood that, for the above-mentioned first communication interruption situation, the first processor 104 outputs a signal for driving the control switch circuit 105 to conduct according to the interrupt signal, connects the first charging circuit 106 and the second charging circuit 204, and controls the second rechargeable battery 201 from the atomization device 100 end to charge the first rechargeable battery 101 through the second charging circuit 204, the switch circuit 105 and the first charging circuit 106, that is, the first processor 104 controls the atomization device 100 to enter the second charging state according to the interrupt signal. For the above-mentioned second communication interruption situation, it is necessary to replenish the power in time. At this time, if it is detected that the first interface 102 is connected to the external power supply, the switch circuit 105 is driven to conduct, connects the first charging circuit 106 and the second charging circuit 204, and controls the external power supply from the atomization device 100 end to reversely charge the second rechargeable battery 201 in time through the first charging circuit 106, the switch circuit 105 and the second charging circuit 204, so that the first processor 104 and the second processor 203 resume communication.

[0090] Figure 5 A schematic diagram of the structure of an atomization system provided in another embodiment of the present application. Figure 5 As shown, the atomization system of this embodiment is based on any of the above embodiments, and the atomization device 100 further includes a first prompt component 107 , and the charging device 200 further includes a second prompt component 205 .

[0091] The first prompt component is connected to the first processor 104, and is used to output a first prompt message when the atomization device 100 is in a first charging state; output a second prompt message when the atomization device 100 is in a second charging state; and output a third prompt message when the atomization device 100 is in a third charging state.

[0092] The second prompt component is connected to the second processor 203, and is used to output fifth prompt information when the atomization device 100 is in the second charging state, and to output sixth prompt information when the atomization device 100 is in the third charging state.

[0093] Among them, the first prompt information, the second prompt information, the third prompt information, the fourth prompt information, the fifth prompt information and the sixth prompt information include at least one of light, light color, pattern and text.

[0094] For example, the first prompt component and the second prompt component are both light prompt components composed of at least one LED light. When the atomization device 100 is in different charging states, it can realize the prompt of the charging state by flashing the light, the light being always on and / or the light color difference. In a feasible embodiment, when the atomization device 100 is in the first charging state, the first prompt component is always on with a red light, and the second prompt component is not on; when the atomization device 100 is in the second charging state, the first prompt component flashes a red light or a marquee, and the second prompt component is always on to display the charging state; when the atomization device 100 is in the third charging state, the first prompt component is always on, and the second prompt component flashes a red light or a marquee.

[0095] For another example, the first prompt component and the second prompt component may both be a display screen, on which the current charging status is displayed through patterns, texts, or a combination of patterns and texts.

[0096] In summary, the atomizing device and charging device provided by any of the above embodiments realize that when there is no external power supply, the atomizing device is charged by the charging device, and when there is an external power supply, the atomizing device charges itself and reversely charges the charging device through the external power supply, thereby extending the single use cycle of the atomizing device and the charging device. In addition, based on the communication channel of the processor between the atomizing device and the charging device, the atomizing device is switched between three charging states, and the problem that the charging device is always on as a power supply is avoided, which will increase the power consumption of the atomizing device and the charging device, accelerate the battery consumption of the charging device, and shorten the single use time of the atomizing device is avoided.

[0097] Figure 6 This is a flow chart of a charging method for an atomization system provided in one embodiment of the present application. The charging method for an atomization system provided in this embodiment is applied to the atomization system described in any of the above embodiments, and its execution subject is an atomization device, such as Figure 6 As shown, the charging method of the atomization system provided in this embodiment specifically includes the following steps:

[0098] Step S601: Acquire the connection status of the first interface and the second interface and the power level of the first rechargeable battery.

[0099] Step S602: Determine and control the atomizing device to enter a corresponding charging state according to the connection state between the first interface and the second interface.

[0100] Among them, the charging state of the atomization device includes a first charging state, a second charging state and a third charging state; the first charging state is that when the first interface is connected to an external power supply, the first rechargeable battery obtains voltage through the external power supply for charging; the second charging state is that when the second interface is connected to the third interface, the first rechargeable battery obtains voltage through the second rechargeable battery for charging; the third charging state is that when the first interface is connected to the external power supply and the second interface is connected to the third interface respectively, and the first rechargeable battery is fully charged, the second rechargeable battery obtains voltage through the external power supply for reverse charging.

[0101] It is understandable that when the atomizing device 100 needs to be charged, it can determine and control the atomizing device 100 to enter a corresponding charging state according to the connection status of its first interface 102 and the second interface 103. This includes charging through the external power supply when the first interface 102 is connected to the external power supply; charging through the charging device 200 when the second interface 103 is connected to the third interface 202 of the charging device 200; and when the first interface 102 is connected to the external power supply, the second interface 103 is connected to the charging device 200, and the first rechargeable battery 101 of the atomizing device 100 is fully charged, the charging device 200 is reversely charged through the external power supply as a medium.

[0102] Figure 7 This is a flow chart of a charging method for an atomization system provided in another embodiment of the present application. Figure 7 As shown, the charging method of the atomization system provided in the above embodiment, step S602, determining to control the atomization device to enter a corresponding charging state according to the connection state of the first interface and the second interface, further specifically includes the following steps:

[0103] Step S701: When the second interface is connected to the third interface, monitor the power level of the first rechargeable battery.

[0104] Step S702: When the acquired power level of the first rechargeable battery does not reach the preset first threshold, the atomizing device is controlled to enter the second charging state; when the acquired power level of the first rechargeable battery reaches the preset first threshold, the atomizing device is controlled not to enter the second charging state.

[0105] It can be understood that after the atomization device 100 and the charging device 200 are connected to the third interface 202 through the second interface 103, the processor of the atomization device 100 first detects the power of the first rechargeable battery 101 to determine whether the first rechargeable battery 101 needs to be charged. When it does not reach the preset first threshold, it enters the second charging state, that is, the second rechargeable battery 201 of the charging device 200 needs to charge the first rechargeable battery 101; when it reaches the preset first threshold, it does not enter the second charging state, that is, the second rechargeable battery 201 is not needed to charge the first rechargeable battery 101 at this time.

[0106] Step S703: when the atomizing device is in the second charging state, detecting the connection state of the first interface;

[0107] Step S704: when it is detected that the first interface is connected to the external power source, the atomizing device is controlled to switch from the second charging state to the first charging state.

[0108] It is understandable that when the atomization device 100 is in the second charging state, that is, when the atomization device 100 is charged through the charging device 200, if it is detected that the first interface 102 is connected to an external power source, the first rechargeable battery 101 of the atomization device 100 will no longer be charged through the second rechargeable battery 201 of the charging device 200, but the first charging state will be switched to charge the first rechargeable battery 101 of the atomization device 100 through the external power source, and the power of the charging device 200 will no longer be consumed, thereby extending the service life of the charging device 200.

[0109] Step S705: When the atomization device is in the first charging state, monitor the power level of the first rechargeable battery.

[0110] Step S706: when it is detected that the power of the first rechargeable battery is fully charged, the atomizing device is controlled to switch from the first charging state to the third charging state.

[0111] It is understandable that when the atomization device 100 is in the first charging state, that is, when the atomization device 100 is charged by an external power supply, if it is measured that the power of the first rechargeable battery 101 is fully charged, that is, the first rechargeable battery 101 is fully charged, the atomization device 100 no longer needs to be charged, and the current first charging state can be switched to the third charging state, so that the external power supply can charge the charging device 200.

[0112] It should be noted that the various steps in the above embodiment are the same or similar to the implementation process and technical effects in the product embodiment, and will not be repeated here to avoid repetition. In addition, steps S701-step S702, steps S703-step S704, and steps S705-step S706 can be executed simultaneously or separately, and this embodiment does not make any specific limitations.

[0113] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the inspiration of the present application, ordinary technicians in the field can make several simple deductions, deformations or substitutions based on the ideas of the present application without departing from the scope of protection of the purpose of the present application and the claims. All of these are within the protection of the present application.
