Description

Technology Field

[0001] The present application relates to a charging control circuit, a method and device, a charging system, and a detachable atomizing device.

[0002] [Related Application]

[0003] This application claims priority to a Chinese patent application filed on June 1, 2021, with application number 202110609640.2 and titled "Charging control circuit, method and apparatus, charging system, detachable atomizing device," all of which are by reference. Background Technology

[0004] In cyclic charging batteries such as lithium-ion batteries, the voltage gradually decreases during the discharge process, and discharge is completed when the voltage drops to the lowest allowable voltage.

[0005] A conventional detachable atomizer includes an atomizer and a dedicated charging case for charging the atomizer. During the process in which the power supply battery of the charging case charges the battery to be charged of the atomizer, the charging control circuit must obtain a continuous voltage from the power supply battery. If, during the charging process, the amount of electricity in the power supply battery is insufficient and the output voltage drops below the minimum allowable output voltage, the output of the power supply battery is interrupted, thereby stopping the charging process, and consequently, the battery to be charged cannot complete a single charging cycle.

[0052] To aid in understanding the present application, the application will be described more comprehensively below with reference to the attached drawings. The drawings illustrate embodiments of the present application. However, the present application is not limited to the embodiments described herein and may be implemented in various other forms. These embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present application.

[0053] All technical and scientific terms used herein have the same meaning as generally understood by those skilled in the art to which this application pertains, unless otherwise defined. The terms used herein are intended to specifically describe the embodiments and are not to be interpreted as limiting the scope of this application.

[0054] The terms "first," "second," etc., used in this application are intended to describe various components and are not limited by such terms. These terms are used solely for the purpose of distinguishing one component from another.

[0055] When an element is referred to as being "connected" to another element, it shall be understood that the element is directly connected to the other element or may be connected through an intermediate element. Furthermore, the term "connection" as used in the embodiments below shall be understood as an "electrical connection," "communication connection," etc., when there is transmission of electrical signals or data between the connected objects.

[0056] As used herein, singular words include plural forms unless the context clearly indicates otherwise. Additionally, terms such as “include” or “compose” mean the presence of the specified configuration, whole, step, action, component, part, or combination thereof, but should not be understood as not excluding the presence or addition of one or more other configurations, whole, step, action, component, part, or combination thereof.

[0057] The battery charging process is divided into four stages: trickle charging, constant current charging, constant voltage charging, and charging termination. When the electric charge of the battery to be charged is too low, the trickle charging mode is used, and the charging current in the trickle charging stage is relatively small to protect the battery. When the battery to be charged rises above the trickle charging threshold, constant current charging is performed. In the constant current charging stage, charging is performed with a fixed current, and the current is relatively high to implement rapid charging. When the voltage of the battery to be charged rises above the constant current charging threshold, for example at 4.2V, the constant voltage charging mode is used, and the charging circuit outputs a fixed voltage. At this time, as the voltage of the battery to be charged gradually increases, the difference between the output voltage of the charging circuit and the voltage of the battery to be charged gradually decreases, so the charging current also gradually decreases. When the charging current falls below the minimum current threshold, the charging cycle is completed by entering the charging termination stage.

[0058] In a detachable atomizer, during the process of charging one battery with another, the charging control circuit must obtain a continuous voltage from the power supply battery. If the power supply battery's electrical capacity is insufficient during the charging process and its output voltage drops below the minimum allowable output voltage, the output is cut off, interrupting the charging process. Consequently, the battery to be charged cannot complete a single charging cycle, preventing full charging, and power outages may occur while the user is using the atomizer, thereby degrading the user experience.

[0059] In order to solve the technical problem described in the background art, in one aspect, an embodiment of the present application provides a charging control circuit comprising a charging circuit (20) and a controller (40). As illustrated in FIG. 1, the input terminal of the charging circuit (20) is configured to be connected to a first battery (60), and the output terminal of the charging circuit (20) is configured to be connected to a second battery (80); the output terminal of the controller (40) is electrically connected to the control terminal of the charging circuit (20), and the controller (40) is configured to obtain information on the remaining electric amount of the first battery (60) to indicate the magnitude of the remaining electric amount of the first battery (60); and when it is determined that at least one charging cycle of the second battery (80) can be completed with the remaining electric amount of the first battery (60) according to the information on the remaining electric amount of the first battery (60), the operation of the charging circuit (20) is controlled so that the first battery (60) charges the second battery (80).

[0060] Here, the charging circuit (20) refers to a circuit capable of obtaining electrical energy from the first battery (60) and charging the second battery (80) with an input signal required for charging the second battery (80). The controller (40) refers to a device having information acquisition capability and control capability, and for example, the controller (40) may be an MCU (Microcontroller Unit), a single-chip microcomputer, a CPU, etc. The controller (40) may obtain information on the remaining electric charge of the first battery (60) by directly connecting to the first battery (60), or obtain information on the remaining electric charge of the first battery (60) by indirectly connecting to the first battery (60) through another device, and the controller (40) may also receive information on the remaining electric charge collected by other components such as other sensors or battery charge / discharge curve measuring devices. The charging control circuit may be applied to a charging control scenario of a detachable atomizing device, and the atomizing device may be configured to atomize solid aerosol generating material. The first battery (60) and the second battery (80) may be lithium batteries. A charging cycle refers to the process of fully charging a completely discharged battery.

[0061] Specifically, during the charging process, the amount of electricity in the first battery (60) is insufficient, causing the output of the first battery (60) to be interrupted. Consequently, the second battery (80) cannot complete one charging cycle and cannot be fully charged, resulting in a problem where the charging effect cannot be guaranteed. To avoid this problem, before charging, the controller (40) first obtains information on the remaining amount of electricity in the first battery (60) and determines whether the current remaining amount of electricity in the first battery (60) is sufficient to support one charging cycle of the second battery (80) based on the information on the remaining amount of electricity. If the determination result is 'YES', the controller (40) controls the charging circuit (20) to operate through a connection line with the charging circuit (20), so that the charging circuit (20) transfers the electrical energy of the first battery (60) to the second battery (80).

[0062] To explain in more detail the implementation process of the charging control circuit (1) provided in the embodiment of the present application, a scenario applied to a detachable atomizer is described as an example. As shown in FIG. 2, when applied to a detachable atomizer, the charging control circuit (1) is placed in the charging device (1000) of the detachable atomizer, and at the same time, the first battery (60) is also placed in the charging device (1000), and the second battery (80), which is set to receive charging from the first battery (60), is placed in the atomizer (2000) of the detachable atomizer, and the charging device (1000) and the atomizer (2000) can be separated and combined. When charging is required, the atomizer (2000) and the charging device (1000) are combined (as shown in FIG. 2), and at this time, the charging circuit (20) and the second battery (80) are electrically connected, and the electrical connection may be a wireless coupling connection or a contact-type electrical connection. Before charging, the controller (40) of the charging control circuit (1) illustrated in FIG. 1 obtains information on the remaining electric charge of the first battery (60). When the controller (40) determines that the current remaining electric charge of the first battery (60) is sufficient to support one charging cycle of the second battery (80) according to the information on the remaining electric charge, the controller (40) of the charging device (1000) controls the charging circuit (20) to operate through a connection line with the charging circuit (20) so that the charging circuit (20) transfers the electrical energy of the first battery (60) to the second battery (80) of the atomizing device (2000), thereby ensuring that the second battery (80) of the atomizing device (2000) can be fully charged, thus ensuring that the second battery (80) can satisfy the operating voltage requirements of the atomizing device (2000) for atomizing aerosol-generating material.

[0063] In another aspect, if the controller (40) determines that at least one charging cycle of the second battery (80) can be completed with the remaining electric amount of the first battery (60) according to the information on the remaining electric amount of the first battery (60), it controls the operation of the charging circuit (20) so that the first battery (60) charges the second battery (80); in other words, if the controller (40) determines that at least one charging cycle of the second battery (80) cannot be completed with the remaining electric amount of the first battery (60) according to the information on the remaining electric amount of the first battery (60), it controls the charging circuit (20) to limit the charging of the second battery (80) by the first battery (60).

[0064] In one embodiment, the remaining electric amount information of the first battery (60) includes the output voltage of the first battery (60), and the controller (40) is also configured to determine that at least one charging cycle of the second battery (80) can be completed with the remaining electric amount of the first battery (60) when the output voltage of the first battery (60) is greater than or equal to a threshold voltage; the threshold voltage is a voltage value that causes the second battery (80) to complete at least one charging cycle. The output voltage of the first battery (60) may represent the remaining electric amount of the first battery (60), and the threshold voltage may be obtained according to the output voltage value corresponding to the remaining electric amount required for one charging cycle of the second battery (80) during the test process. If the output voltage of the first battery (60) is lower than the threshold voltage, this means that the current remaining electric charge of the first battery (60) is not sufficient to support one charging cycle of the second battery (80). In other words, the output of the first battery (60) is interrupted due to a lack of electric charge during the charging process, and the second battery (80) may not be fully charged. Consequently, when a user uses the atomizer equipped with the second battery (80) in the future, a power outage may occur, which may affect the usage effect. At this time, the controller (40) controls the charging circuit (20) to prevent charging from starting; that is, the charging circuit (20) limits the charging of the second battery (80) by the first battery (60) under the control of the controller (40). Here, the threshold voltage may be a voltage of 3.2V.

[0065] When the controller (40) determines that the remaining electric charge is sufficient to support one charging cycle according to the output voltage of the first battery (60), that is, only when the output voltage of the first battery (60) is above a threshold voltage, the controller (40) controls the charging circuit (20) to start a charging operation, and the charging circuit (20) transfers the electrical energy of the first battery (60) to the second battery (80) to supply power to the second battery (80) until the second battery (60) is fully charged, and stops operating when it is fully charged. The charging control circuit provided in the embodiment of the present application ensures that at least one complete charging cycle can be quickly completed for every charge, so that the second battery (80) can be quickly fully charged, thereby improving the user experience.

[0066] In one embodiment, as shown in FIG. 3, the first battery (60) is connected across two input terminals of the controller (40), and the controller (40) is configured to collect the output voltage of the first battery (60). As shown in FIG. 3, the two input terminals of the controller (40) are each connected to the positive and negative terminals of the first battery (60) to obtain the voltage across the first battery (60), and since the magnitude of the output voltage can indicate the amount of remaining electricity of the battery, by using the connection method of FIG. 3, the controller (40) can obtain voltage information that indicates the magnitude of the remaining electricity of the first battery (60) and provide a data basis for determining the start of subsequent charging. It should be noted that the residual electric amount information indicating the magnitude of the remaining electric amount of the battery is not limited to the output voltage of the first battery (60) and may be the output current of the first battery (60), and the controller (40) can obtain the amount of the remaining electric amount of the first battery (60) by collecting the output current of the first battery (60).

[0067] In one embodiment, the charging control circuit further includes a first resistor (R1) and a second resistor (R2), the second resistor (R2) is connected in series with the first resistor (R1), and the second resistor (R2) is a resistor connected across two input terminals of the controller (40), and the controller (40) is configured to collect the output voltage of the first battery (60) (BAT1).

[0068] As illustrated in FIG. 3, the controller (40) can also connect the first resistor (R1) and the second resistor (R2) in series and then connect them across both ends of the first battery (60), and then draw a lead wire from the connection point of the first resistor (R1) and the second resistor (R2) to the controller (40) using a voltage division method, and the controller (40) can collect the voltage across the second resistor (R2) using this voltage division method, and then obtain the output voltage of the first battery (60) according to the resistance values ​​of the second resistor (R2) and the first resistor (R1), and determine the output voltage of the first battery (60) as the remaining electric charge information of the battery.

[0069] In one embodiment, as illustrated in FIG. 4, the controller (40) is also configured to perform a notification operation to remind the user to charge the first battery (60) (BAT1) when the output voltage of the first battery (60) (BAT1) is less than the threshold voltage. When the output voltage of the first battery (60) (BAT1) is less than the threshold voltage, this means that the remaining electric charge of the first battery (60) (BAT1) is not sufficient to support one charging cycle of the second battery (80) (BAT2). At this time, the controller (40) can simultaneously perform a notification operation to remind the user to charge the first battery (60), so that when the atomizing device is to be used, the first battery (60) (BAT1) has a sufficient remaining electric charge to supply to the second battery (80) (BAT2), and the second battery (80) (BAT2) is fully charged and the device is operated to proceed with atomization. It should be noted that the atomizing device described as an example in this specification is merely to more clearly explain the operation implementation process and beneficial effects of the charging control circuit provided in the embodiments of this application, and that the charging control circuit is not limited to atomizing device scenarios and may be applied to other devices.

[0070] In one embodiment, the controller (40) is configured to drive an LED light to be turned on and / or to display notification information on a display screen and / or to drive a vibration motor to operate and / or to send notification information to a remote terminal when it is determined that at least one charging cycle of the second battery (80) cannot be completed with the remaining electric amount of the first battery (60) according to the information on the remaining electric amount of the first battery (60). To achieve a better notification effect, in the charging circuit (20) according to an embodiment of the present application, the controller (40) also drives the operation of the LED light when the remaining electric amount of the first battery (60) is insufficient to support one charging cycle of the second battery (80), thereby reminding the user to charge the first battery (60). Here, the LED light may be placed in a device in which an operating voltage is provided by the second battery (80). For example, the LED light may be placed in an atomizing device in which an operating voltage for atomizing an aerosol generating material is provided by the second battery (80). To enhance the notification effect of the LED light, the LED light may be placed by being embedded in the housing of the atomizing device.

[0071] The notification action may also be a controller (40) driving the display screen to display notification information, which may be information that reminds the user to charge the first battery (60), such as "The electric charge of the first battery (60) is insufficient and needs to be charged," or a symbol that has an alarm function, such as "!". The display screen may be a screen embedded in an object powered by the second battery (80), for example, the display screen may refer to a screen on an atomizer powered by the second battery (80), and the screen may be embedded and placed on the housing of the atomizer. The display screen may be a screen of a remote terminal such as a mobile phone or tablet, and the controller (40) transmits notification information to the display screen and drives the display screen to display the notification information when it is determined through a wired or wireless communication connection with the display screen that the remaining electric charge of the first battery (60) is insufficient to support one charging cycle of the second battery (80), thereby achieving the purpose of reminding the user to charge the first battery (60).

[0072] The vibration motor may be a vibration motor integrated into a target powered by the second battery (80) or a vibration motor integrated into a terminal such as a user's mobile phone. If it is determined that the remaining electric charge of the first battery (60) is insufficient to support one charging cycle of the second battery (80), the controller (40) drives the vibration motor to operate via a wired or wireless connection with the vibration motor, and the user recognizes that the remaining electric charge of the first battery (60) is insufficient and charging is required by detecting the vibration.

[0073] Currently, mobile terminals such as mobile phones and tablets have become indispensable necessities in people's lives, and users basically carry at least one mobile terminal device. Taking this into account, if the controller (40) determines that the remaining electric charge of the first battery (60) is not sufficient to support one charging cycle of the second battery (80), it can transmit notification information to the remote terminal and display it on the remote terminal.

[0074] To further enhance the notification effect, when the output voltage of the first battery (60) is lower than the threshold voltage, that is, when it is determined that the remaining electric charge of the first battery (60) is not sufficient to support one charging cycle of the second battery (80), the controller (40) can simultaneously perform a plurality of operations during the notification operation to remind the user to charge the first battery (60).

[0075] In one embodiment, the controller (40) is configured to control the charging circuit (20) according to the current voltage state of the second battery (80) to charge the second battery (80) in a target charging mode, and the target charging mode includes one or more selected from a trickle charging mode, a constant current charging mode, a constant voltage charging mode, and a charging termination mode. To optimize the charging performance of the second battery (80), the voltage tolerance is controlled to be within ±1%. When the controller (40) controls the operation of the charging circuit (20), it further considers the current voltage state of the second battery (80) and selects a different charging mode according to the battery condition of the second battery (80). As described in the above embodiment, if the voltage of the second battery (80) is too low, it means that the current remaining electric charge of the second battery (80) is too low. Therefore, at this time, charging must first be started in a trickle charging mode, and then, referring to the above embodiment, the charging mode is sequentially changed until the charging current of the charging circuit (20) is lower than the minimum current threshold, and then enters the charging end stage to complete the charging cycle.

[0076] In one embodiment, the controller (40) is configured to control the charging circuit (20) to charge the second battery (80) in a trickle charging mode, a constant current charging mode, a constant voltage charging mode, and a charging end mode during the charging cycle when the voltage of the second battery (80) is lower than a first threshold value before charging begins. The first threshold value may be a threshold voltage indicating the end of trickle charging, for example, the first threshold value may be a voltage value of 2V. If the voltage of the second battery (80) is lower than the first threshold value, this means that the remaining electric charge of the second battery (80) is too low, and the charging circuit (20) first precharges the completely discharged second battery (80) in a trickle charging mode. Subsequently, as described in the above embodiment, depending on the magnitude of the output voltage during the charging process of the second battery (80), the charging circuit (20) sequentially charges the second battery (80) in a constant current charging mode, a constant voltage charging mode, and a charging end mode.

[0077] In one embodiment, the controller (40) is configured to control the charging circuit (20) to charge the second battery (80) in a constant current charging mode, a constant voltage charging mode, and a charging termination mode during the charging cycle when the voltage of the second battery (80) is greater than a first threshold value and less than a second threshold value before charging begins.

[0078] The second threshold is a voltage corresponding to the end of the constant current charging stage during the charging process. For example, the second threshold may be a voltage value of 3.6V. If the voltage of the second battery (80) is greater than the first threshold before starting charging, this indicates that the voltage of the second battery (80) is not too low. If it is determined that the voltage of the second battery (80) is also less than the second threshold in order to proceed with rapid charging, it indicates that the battery to be charged is suitable for the constant current charging mode. In the constant current charging mode, the charging circuit (20) can be controlled to proceed with charging at the first current, and the first current may be 3A. The first current is not further reduced to rapidly charge the second battery (80) during the entire constant current charging stage.

[0079] If, before charging begins, the voltage of the second battery (80) is greater than the second threshold and less than the third threshold, the charging circuit (20) is controlled to charge the second battery (80) in a constant voltage charging mode and a charging end mode during the charging cycle. Here, the third threshold is a voltage corresponding to the end of the constant voltage charging stage. For example, the third threshold may be a voltage value of 3.65V. If the voltage of the second battery (80) is greater than 3.6V and less than 3.65V, the charging circuit (20) enters the constant voltage charging stage and charges the second battery (80) with a constant voltage until the voltage of the second battery (80) reaches 3.65V, and then the charging circuit (20) enters the charging end mode and the charging of the second battery (80) is completed.

[0080] In another aspect, as illustrated in FIGS. 1 to 4, an embodiment of the present application provides a charging system comprising a first battery (60) configured to charge a second battery (80), a second battery (80), and the aforementioned charging control circuit.

The first battery (60) may be mounted on the same device as the second battery (80), and the first battery (60) primarily serves to charge the second battery (80). For example, the first battery (60) and the second battery (80) may be placed in the first part and the second part, which is detachable from the first part, respectively, of a detachable atomizing device. The charging system may be applied to an atomizing device for atomizing an aerosol generating substance. Refer to the description of the above embodiment for the process in which the charging control circuit proceeds with charging control of the second battery (80) according to the state of the first battery (60) and the second battery (80), and redundant description is omitted.

[0083] Here, the atomizing device (2000) refers to a component capable of receiving an aerosol-generating material and atomizing it, for example, the aerosol-generating material may be a solid material of plant leaves to which one or more of menthol, fruit flavoring, plant essential oil, or nut flavoring have been added, and the aerosol-generating material may be a liquid atomizable fragrance material. As illustrated in FIGS. 2 and 5, a second battery (80) is placed in the atomizing device (2000), and the second battery (80) is configured to supply an operating voltage to the material atomizing portion of the atomizing device (2000). When charging is required, the charging control circuit (1) placed in the charging device (1000) obtains information on the remaining electric charge of the first battery (60), and if it is determined that the current remaining electric charge of the first battery (60) is sufficient to support one charging cycle of the second battery (80) according to the information on the remaining electric charge, the controller (40) of the charging control circuit (1) controls the charging circuit (20) to transfer the electric energy of the first battery (60) to the second battery (80) of the atomizing device (2000), thereby ensuring that the second battery (80) of the atomizing device (2000) can be fully charged, thus ensuring that the second battery (80) can satisfy the atomizing operating voltage requirements of the atomizing device (2000).

At this time, if the controller (40) determines that the remaining electric charge of the first battery (60) is sufficient to support one charging cycle of the second battery (80), the controller (40) controls the operation of the charging circuit (20) so that the first battery (60) charges the second battery (80).

[0085] In one embodiment, as illustrated in FIGS. 5 and 6, the housing (1100) of the charging device (1000) includes a fixed part having a groove (1500) and a cover (1600).

When the cover (1600) is closed, the atomizing device (2000) is stably positioned in the second receiving cavity (1300), thereby improving charging reliability. Furthermore, due to this structure, the attachment and detachment of the atomizing device (2000) is very convenient and provides a good user experience. In one embodiment, one side of the cover (1600) can be rotatably connected to a fixed part having a groove (1500) through a rotation axis (1700), and with this structure, the cover (1600) can be prevented from being lost.

Additionally, the charging control circuit (1) may control the first voltage indicator (1800) and / or the electric amount indicator (1900) to light up when it is monitored that the remaining electric amount of the first battery (60) is not sufficient to support one charging cycle of the second battery (80).

[0087] In one embodiment, as illustrated in FIGS. 5 and 7, the atomizing device (2000) includes a housing (2200), and a third receiving cavity (2300) for receiving a second battery (80) is formed in the housing (2200). The atomizing device (2000) further includes an atomizing circuit board (2400) and a heating element (2500). A fourth receiving cavity (2600) communicating with the outside is further formed in the housing (2200) of the atomizing device (2000). The fourth receiving cavity (2600) is configured to receive the material. A portion of the heating element (2500) is configured to extend into the fourth receiving cavity (2600) to heat and atomize the material within the receiving cavity. Another portion of the heating element (2500) is electrically connected to the atomizing circuit board (2400) within the third receiving cavity (2300). The atomizing circuit board (2400) is connected and controls the operating state of the heating element (2500) by power supply from the second battery (80) to implement atomizing control.

[0088] In one embodiment, as illustrated in FIGS. 5 and 7, the atomizing device (2000) further includes a second voltage indicator (2700), the second voltage indicator (2700) is connected to an atomizing circuit board (2400) within a third receiving cavity (2300), and the atomizing circuit board (2400) can control the operating state of the second voltage indicator (2700) according to the power supply voltage and residual voltage conditions of the second battery (80). For example, a means for controlling the first voltage indicator (1800) with the charging control circuit (1) described in the above embodiment may be referenced, and a redundant description is omitted. In one embodiment, the second voltage indicator (2700) may communicate with the outside by passing through a through hole on the housing (2200) of the atomizing device (2000). The second voltage indicator (2700) may also be placed inside the third receiving cavity (2300) of the atomizing device (2000) and placed in close contact with the side wall of the housing (2200), and the portion of the housing (2200) where the second voltage indicator (2700) is placed is made of a transparent material so that the light of the second voltage indicator (2700) can pass through the housing (2200).

[0089] To better explain the process of using the above-mentioned separable atomizing device, the explanation is given using the example of a solid aerosol generating substance; however, it should be noted that the above-mentioned separable atomizing device can also be used for atomizing other substances or complex substances, such as fruit substances or vanilla substances.

[0090] When the atomizing circuit board (2400) detects that the amount of electricity in the second battery (80) is insufficient to support the amount of electricity required for one atomization of the aerosol generating material (3000) according to the output voltage of the second battery (80), the second voltage indicator (2700) is controlled to operate in a first state to remind the user to charge the atomizing device (2000), and in the first state, the second voltage indicator (2700) may light up in red. By opening the cover (1600) of the charging device (1000) and placing the atomizing device (2000) in the groove (1500), the power supply terminal (2100) of the atomizing device (2000) connected to the second battery (80) is matched and connected to the charging terminal (1400) placed on the inner wall of the groove (1500). At this time, when the cover (1600) is closed, the atomizing device (2000) is stably accommodated in the second receiving cavity (1300). At this time, if the controller (40) in the first receiving cavity (1200) determines that the remaining electric amount is sufficient to support one charging cycle of the second battery (80) according to the information on the remaining electric amount of the first battery (60), the controller (40) controls the charging circuit (20) to operate so that the electric amount of the first battery (60) is processed and then supplied to the second battery (80). At this time, the controller (40) can also control the first voltage indicator (1800) and the electric amount indicator (1900) to operate in a first state. In the first state, the first voltage indicator (1800) may not be lit or may be lit in green, and the electric amount indicator (1900) may not be lit or may be lit in green.

[0091] When the controller (40) in the first receiving cavity (1200) determines, based on the information regarding the remaining electric amount of the first battery (60), that the remaining electric amount of the first battery (60) is not sufficient to support at least one charging cycle of the second battery (80), the controller (40) controls the first voltage indicator (1800) and the electric amount indicator (1900) to operate in a second state, thereby reminding the user that power supply to the second battery (80) cannot be guaranteed at present and reminding the user to charge the first battery (60). In the second state, the first voltage indicator (1800) may be lit or illuminated in red, and the electric amount indicator (1900) may be lit or illuminated in red.

[0092] When the atomizing circuit board (2400) detects that the amount of electricity in the second battery (80) is sufficient to support the amount of electricity required for one atomization of the aerosol generating material (3000) according to the output voltage of the second battery (80), the atomizing circuit board (2400) controls the second voltage indicator (2700) to operate in a second state, thereby informing the user that baking of the aerosol generating material can be performed with the current atomizing device (2000) and that the baking effect can be guaranteed. In the second state, the second voltage indicator (2700) may be lit in green or may not be lit. The user places a solid aerosol generating material (3000) into the fourth receiving cavity through the fourth receiving cavity and an external communication part, and the atomizing circuit board (2400) controls the heating element (2500) to operate by power supply from the second battery (80), and the heating element (2500) heats and bakes the solid aerosol generating material (3000).

[0096] Here, the meaning of terms such as "remaining electric capacity information" is the same as in the above embodiment, and redundant explanation is omitted. When it is determined that the remaining electric capacity of the first battery is sufficient to support one charging cycle of the second battery based on the acquired information on the remaining electric capacity of the first battery, charging is started at this time so that the problem of charging interruption due to insufficient electric capacity of the first battery does not occur.

[0107] In one embodiment, the step of charging the second battery to a target charging mode during the charging cycle according to the voltage state of the second battery is,

[0108] If the voltage of the second battery is lower than a first threshold value before charging begins, the step of charging the second battery during a charging cycle in a trickle charging mode, a constant current charging mode, a constant voltage charging mode, and a charging termination mode;
