[0003] The present application relates to the field of aerosol provision, particularly to an aerosol provision system, a use method, a computer device, and a storage medium.

[0004] Background

[0005] For electronic cigarette heating systems, compared with power systems with a single battery, the power systems with multiple batteries (referring to 2 or more batteries) can achieve the same power level with smaller current, and the power systems with multiple batteries can provide a higher voltage (for example, a conventional single battery power system can provide a voltage of 3.7V, while a power system with 2 batteries can provide a voltage of 7.4V). Higher voltage will generate higher power to heat the heating element and help reduce power loss during atomization, improving heating efficiency.

For example, the common 5V adapter on the market cannot charge the power system (7.4V) with two batteries mentioned above, and a 9V or 12V adapter needs to be provided for charging. However, the 9V or 12V adapter is not a popular adapter for consumer products and needs to be customized, which increases the product cost. Alternatively, a boost or a charge pump can be added to the 5V adapter to increase the input voltage, but adding a boost or a charge pump to the circuit will be more complicated and costly.

[0030] Additional aspects and advantages will be partially presented in the following description, some of which will become apparent from the following description.

[0066] A consumable is an article comprising or consisting of aerosol-generating material, part or all of which is intended to be consumed during use by a user. A consumable may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generation area, a housing, a wrapper, a mouthpiece, a filter and / or an aerosol-modifying agent. A consumable may also comprise an aerosol generator, such as a heater, that emits heat to cause the aerosol-generating material to generate aerosol in use. The heater may, for example, comprise combustible material, a material heatable by electrical conduction, or a susceptor.

[0067] A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

[0068] An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavour, acidity or another characteristic of the aerosol. The aerosolmodifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosol-modifying agent. The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosol-modifying agent may, for example, comprise one or more of a flavourant, a colourant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0069] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol- generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0070] The present disclosure relates to aerosol delivery systems (which may also be referred to as vapour delivery systems) such as nebulisers or e-cigarettes. Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol delivery system I device and electronic aerosol delivery system I device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0071] Aerosol delivery systems (e-cigarettes) often, though not always, comprise a modular assembly comprising a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will comprise the aerosol-generating material and the vaporiser (which may collectively be called a “cartomizer” ) and the reusable device part will comprise the power provision (e.g. rechargeable power source) and control circuitry. It will be appreciated these different parts may comprise further elements depending on functionality. For example, the reusable device part will often comprise a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part in some cases comprises a temperature sensor for helping to control temperature. Cartridges are electrically and mechanically coupled to the control unit for use, for example using a screw thread, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol-generating material in a cartridge is exhausted, or the user wishes to switch to a different cartridge having a different aerosol-generating material, the cartridge may be removed from the reusable part and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-part modular configuration may generally be referred to as two-part systems / devices.

[0072] It is common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure will be taken to comprise this kind of generally elongate two-part system employing disposable cartridges. However, it will be appreciated that the underlying principles described herein may equally be adopted for different configurations, for example single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposables, as well as other overall shapes, for example based on so-called box-mod high performance devices that typically have a boxier shape. More generally, it will be appreciated certain embodiments of the disclosure are based on aerosol delivery systems which are operationally configured to provide functionality in accordance with the principles described herein and the constructional aspects of systems configured to provide the functionality in accordance with certain embodiments of the disclosure is not of primary significance.

[0073] As described in the technical background, the existing aerosol provision system, if powered by a battery assembly with multiple batteries, can provide a higher voltage to generate higher power heating elements, reduce power loss during the atomization process, and improve heating efficiency. However, in this way, the commonly used adapters will not be able to charge the battery assembly. If additional customized adapters are used or a boost or a charge pump is added to the charging circuit to increase the input voltage, this will increase product costs.

[0074] Embodiment one

[0075] Figure 1 shows a schematic diagram of a circuit structure of an aerosol provision system. Referring to Figure 1 , the system generally comprises a battery assembly 100, a switching assembly 200, a control module 300, a charging interface 400, a heating element 500, and a charging integrated circuit 600.

[0076] As further shown in Figure 1 , the battery assembly 100 includes at least two batteries connected to each other, which can provide a higher voltage when supplying power to the heating element 500. The switching assembly 200 is configured to be connected to the battery assembly 100, and used to switch the connection mode between the at least two batteries of the battery assembly 100. The connection mode includes a series connection and a parallel connection. The control module 300 is connected to the switching assembly 200 The control module 300 is configured to control the switching assembly 200 to switch the connection mode between at least two batteries to series connection when the aerosol provision system is detected to be in a first mode, and to switch the connection mode between at least two batteries to parallel connection when the aerosol provision system is detected to be in a second mode. The first mode is the power supply mode, in which the battery assembly 100 can supply power to the heating element, and the second mode is the charging mode, in which the battery assembly 100 can be charged.

[0077] The first mode is a first operating mode and the second mode is a second operating mode.

[0078] The charging interface 400, heating element 500, and charging integrated circuit 600 are all connected to the battery assembly 100. The charging interface 400 and charging integrated circuit 600 are mainly used to provide access to an external power source to charge the battery assembly. The heating element 500 is mainly used to convert the electrical energy provided by the battery assembly 100 into thermal energy to heat the aerosol generating material and generate aerosols for users to puff.

[0079] It can be understood that when at least two batteries are connected in series, the battery assembly can provide a higher voltage. Taking a battery assembly with two batteries and a single battery output voltage of 3.7V as an example, when two batteries are connected in series, the output voltage of the battery assembly increases to 7.4V. At this time, the battery assembly can provide a higher voltage to the heating element to generate a higher power for heating. When two batteries are connected in parallel, the output voltage of the battery assembly is still 3.7V. A conventional adapter (such as 5V) may still be used to charge the battery assembly without the need for special adapters or adding a boost or charge pump in the charging circuit to increase the input voltage, for example, thereby helping reduce product costs.

[0080] It should be noted that the embodiments do not impose specific limitations on the number of batteries contained in the battery assembly 100. Users can arrange it according to actual product requirements. For example, the battery assembly can contain two, three, four, or more batteries. In embodiments, the batteries for the battery assembly 100 in the embodiments are a commonly used specification battery on the market, so that no additional customization is required, thereby reducing product costs. In embodiments, the specifications of the multiple batteries for the battery assembly 100 are the same, so that when switching them to a parallel connection mode for charging, a universal adapter can be used, without the need for a special adapter or adding a boost or a charge pump in the charging circuit to increase the input voltage, thereby reducing product costs.

[0081] For convenience, the present application will be described with the battery assembly 100 having two batteries of the same specification.

[0082] In embodiments, the battery assembly 100 is composed of a first battery 110 and a second battery 120, and the switching assembly 200 is composed of a first switch S1 , a second switch S2, and a third switch S3. It should be noted that in embodiments, there is no specific limitation on the number of switches included in the switching assembly 200. Users can choose according to their actual product requirements.

[0083] As further shown in Figure 1 , the first switch S1 is connected between the first battery 110 and the second battery 120, the second switch S2 is connected between the charging interface 400 and the second battery 120, and the third switch S3 is connected between the first battery 110 and the second battery 120. In embodiments, the two ends of the first switch S1 are respectively connected to the positive electrode of the first battery 110 and the negative electrode of the second battery 120, the two ends of the second switch S2 are respectively connected to the charging interface 400 and the negative electrode of the second battery 120, and the two ends of the third switch S3 are respectively connected to the positive electrode of the first battery 110 and the positive electrode of the second battery 120. Therefore, when the first switch S1 is closed, the second switch S2, and the third switch S3 are opened, the connection between the first battery 110 and the second battery 120 is in series. When the first switch S1 is opened, the second switch S2, and the third switch S3 are closed, the connection between the first battery 110 and the second battery 120 is in parallel. The connection between the first battery 110 and the second battery 120 can be switched by switching the first switch S1 , the second switch S2, and the third switch S3 on and off.

[0084] It can be understood that the battery assembly 100 in the embodiments is mainly used to supply power to the heating element 500, so when the heating element 500 is operated, the heating element 500 is electrically connected to each battery in the battery assembly 100. The heating element 500 is electrically connected to both the first battery 110 and the second battery 120 during operation, so that the first battery 110 and the second battery 120 can supply power to the heating element 500. In addition, some other components in the aerosol provision system may also need to consume some electrical energy to operate, such as the control module 300. However, compared to the electrical energy required by the heating element 500, the electrical energy required by the control module 300 and other components is relatively less. Therefore, in embodiments, all batteries in the battery assembly 100 can be used to power them, or one of the batteries in the battery assembly 100 can be used to power them. That is, both the first battery 110 and the second battery 110 can be connected to the control module 300 so that the first battery 110 and the second battery 120 can supply power to the control module 300 at the same time, or one of the first battery 110 and the second battery 110 can be connected to the control module 300 so that one of the first battery 110 and the second battery 120 can supply power to the control module 300.

[0085] In embodiments, the first battery 110 is used to supply power to the control module 300. Therefore, regardless of whether the heating element 400 of the aerosol provision system is operated or not, the first battery 110 is always in operation (the first battery 110 continuously supplies power to the control module 300), so the voltage of the first battery 110 may be lower than that of the second battery 120. However, it is well known to those skilled in the art that charging two batteries in parallel with unequal voltages at the same time may cause damage to the batteries.

[0086] The aerosol provision system according to embodiments is also provided with a detection module (not shown in the figures), which is configured to detect the current voltage of the first battery 110 and the second battery 120 when the control module 300 detects that the aerosol provision system is in the second mode (charging mode). When the detection module (not shown) detects that the current voltages of the first battery 110 and the second battery 120 are the same, the first battery 110 and the second battery 120 can be charged simultaneously. Therefore, the control module 300 controls the first switch S1 to open, the second switch S2 and the third switch S2 to close, so that the connection between the first battery 110 and the second battery 120 is switched to parallel. After that, the external power supply is connected to the charging interface 400 through the adapter, so as to charge the first battery 110 and the second battery 120 simultaneously. When the detection module (not shown in the figure) detects that the current voltages of the first battery 110 and the second battery 120 are different, the control module 300 controls the first switch S1 to open and the second switch S2 to close to switch the aerosol provision system to the third mode. In the third mode, the battery with a lower current voltage can be charged first until the current voltages of the first battery 110 and the second battery 120 are the same, and then the third switch S3 is closed to switch the aerosol provision system to the second mode, so that the connection mode between the first battery 110 and the second battery 120 is switched to parallel, so that the first battery 110 and the second battery 120 can be charged at the same time.

[0087] It can be understood that due to the use of the first battery 110 to supply power to the control module 300 in the embodiment, the first battery 110 is always in operation (the first battery 110 continuously supplies power to the control module 300), so the detection module may detect that the current voltage of the first battery 110 is lower than the current voltage of the second battery 120. In combination with the connection mode between the above- mentioned switching assembly and each battery, when the first switch S1 is opened and the second switch S2 is closed (i.e. in the third mode), after the external power supply is connected to the charging interface 400 through the adapter, only the first battery 110 can be charged, but the second battery 120 cannot be charged.

[0088] Based on this, in embodiments, after the aerosol provision system is switched to the third mode, an external power supply is connected to the charging interface 400 through an adapter. The first battery 110 with a lower current voltage is charged first, until the current voltage of the first battery 110 and the second battery 120 are the same, and then the third switch S3 is closed to switch the aerosol provision system to the second mode, so that the connection mode between the first battery 110 and the second battery 120 is switched to parallel, so as to charge the first battery 110 and the second battery 120 at the same time. This arrangement can avoid simultaneous charging when the voltages of the first battery 110 and the second battery 120 are unequal, which may cause damage to the first battery 110 and the second battery 120.

[0089] In embodiments, the control module 300 comprises a microcontroller. The microcontroller in the embodiments can be a microcontroller carried by the aerosol provision system itself, so that there is no need to increase the hardware cost of the aerosol supply system. The detection module can be integrated into the control module 300, or it can be a separate assembly communicatively connected to the control module. In embodiments, the detection module in the embodiments is integrated into the control module 300, that is, the functionality of the detection module is implemented through the control module 300, which can further reduce the hardware cost of the aerosol provision system.

[0090] In embodiments, the connection between the charging interface 400 and the first battery 110 and the second battery 120 can be controlled by controlling the on and off of each switch of the switching assembly 200. When the first switch S1 is opened and the second switch S2 and the third switch S3 are closed, in addition to switching the connection mode between the first battery 110 and the second battery 120 to parallel, the charging interface 400 is also in a connected state with both the first battery 110 and the second battery 120. At this time, the external power supply is connected to the charging interface 400 through the adapter, and the first battery 110 and the second battery 120 will be charged at the same time. When the first switch S1 is opened and the second switch S2 is closed, the charging interface 400 is connected to the first battery 110 and disconnected from the second battery 120. At this time, the external power supply is connected to the charging interface 400 through the adapter, and only the first battery 120 will be charged.

[0091] As further shown in Figure 1 , the charging integrated circuit 600 is connected between the charging interface 400 and the battery assembly 100. It can be understood that the charging integrated circuit 600 can convert the external power supply to charge the battery assembly 100. The charging integrated circuit 600 is not specifically limited in the embodiment. Under the premise of not violating the inventive concept of the present application, any known charging integrated circuit 600 can be used in the embodiments.

[0092] In embodiments, there are no specific requirements for the heating element 500. Any known heating element applicable to the aerosol supply system can be used in the embodiments.

[0093] Embodiment two

[0094] Corresponding to the Embodiment one mentioned above, the present application also provides a use method for an aerosol provision system, which is applied to the aerosol provision system as described in Embodiment one. In this embodiment, the same or similar content as the Embodiment one mentioned above can be referred to the above introduction, and will not be repeated in the later. Referring to Figure 2, the method comprises the following steps:

[0095] S100: determining the mode of the aerosol provision system, where the mode comprises at least a first mode and a second mode.

[0096] S200: according to the mode of the aerosol provision system, switching the at least two batteries to a corresponding connection mode, wherein, the connection mode comprises at least series connection and parallel connection, in the first mode, the at least two batteries are switched to series connection, and in the second mode, the at least two batteries are switched to parallel connection.

[0097] S300: The battery assembly operates when the at least two batteries are in series connection or the battery assembly is charged when the at least two batteries are in parallel connection. In embodiments, the use method is mainly applicable to an aerosol provision system in which the battery assembly has multiple batteries. As an illustrative rather than limiting example, the first mode is the power supply mode, in which the battery assembly can supply power to the heating element, and the second mode is the charging mode, in which the battery assembly can be charged.

[0098] In embodiments, in the first mode (power supply mode), at least two batteries of the battery assembly are switched to series connection, which increases the output voltage of the battery assembly. At this time, the battery assembly can provide a higher voltage to the heating element to generate higher power for heating. In the second mode (charging mode), at least two batteries of the battery assembly are switched to parallel connection, and the output voltage of the battery assembly is still the same as that of a single battery. At this time, the battery assembly can still be charged with a conventional adapter (such as 5V), without using a special adapter or adding a boost or a charge pump in the charging circuit to increase the input voltage, thereby reducing product costs.

[0099] In embodiments, the battery assembly comprises at least a first battery and a second battery, and the method further comprises: detecting the current voltages of the first battery and the second battery; when the current voltages of the first battery and the second battery are the same, switching the at least two batteries to parallel connection to switch the aerosol provision system to the second mode, and to charge the first battery and the second battery at the same time; when the current voltages of the first battery and the second battery are different, switching the aerosol provision system to a third mode, to charge the battery with a lower current voltage first, until the current voltages of the first battery and the second battery are the same, then switching the at least two batteries to parallel connection to switch the aerosol provision system to the second mode, and then charging the first battery and the second battery at the same time.

[0100] It can be understood that, in addition to supplying power to heating element, the battery assembly may also need to supply power to other components such as control modules. In an embodiment, depending on the power requirements of the components, only one of the batteries in the battery assembly may be used to supply power to the relevant components, while the battery supplying power to other components is always in operation regardless of whether the heating element of the aerosol supply system is in operation, so its voltage may be lower than that of other batteries. However, it is well known to those skilled in the art that charging two batteries in parallel with unequal voltages at the same time may cause damage to the batteries.

[0101] In embodiments, the use will detect the current voltage of the first battery 110 and the second battery 120 when the control module 300 detects that the aerosol provision system is in the second mode (charging mode). When the current voltages of the first battery and the second battery are detected to be the same, the first battery and the second batter can be charged simultaneously. Therefore, the connection between the first battery and the second battery is switched to parallel, and both batteries are charged simultaneously. When the current voltages of the first battery and the second battery are detected to be different, if the first battery and the second battery are charged at the same time, the battery will be damaged. Therefore, in embodiments, the aerosol provision system will be switched to the third mode. In the third mode, only the battery with a lower current voltage can be charged until the current voltages of the first battery and the second battery are the same. And then the aerosol provision system will be switched to the second mode, so that the connection mode between the first battery and the second battery is switched to parallel, so that the first battery and the second battery can be charged at the same time, thus realizing the protection of the battery assembly.
