Description

Technical Field

[0001] The utility model belongs to the technical field of novel tobacco, and particularly relates to an aerosol generating device. Background Art

[0002] Disposable e-cigarettes and cartridge-type e-cigarettes are two popular small e-cigarettes on the market. These e-cigarettes are characterized by their small size, compact structure, and ease of portability. Generally speaking, with disposable e-cigarettes, once the e-liquid is consumed, the e-cigarette is simply discarded, which undoubtedly results in a waste of resources and environmental pollution. With cartridge-type e-cigarettes, while the e-liquid can be easily replaced after depletion, it is still discarded by the user when it is discarded (for example, due to a malfunction), which also results in environmental pollution and waste of resources. Furthermore, the power supply module of the e-cigarette has other issues, such as a single function. Therefore, improvements to e-cigarettes are needed to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0042] The following is an explanation of the implementation of the present invention by means of specific specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide an in-depth understanding of the present invention, the following description will contain many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0043] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0044] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, the utility model provides an aerosol generating device 1, which includes:

[0047] The housing 2 has a first opening 2.1. The first opening 2.1 is located in the housing 2 along the axial direction Y (eg Figure 1 , Figure 3-4 and Figure 6 one end of the Y direction);

[0048] a power supply module 3 for supplying power to the aerosol generating device 1 to generate aerosol for the user to inhale;

[0049] The power supply module 3 is detachably connected to the housing 2 . The power supply module 3 enters (preferably is embedded in) the housing 2 from the first opening 2 . 1 along the axial direction Y and can be removed from the housing 2 .

[0050] By adopting the above technical solution, the user can easily make the power supply module 3 enter the shell 2 or remove it from the shell 2 along the axial direction Y, so that when the power supply module 3 fails or runs out of power, the power supply module 3 can be quickly replaced without discarding or replacing the entire aerosol generating device 1. It not only avoids environmental pollution, but also reduces resource waste, conforms to the mainstream environmental protection concept, and also responds to the EU's new battery (EU) 2023 / 1542 regulations. In addition, the utility model provides a first opening 2.1 at one end of the shell 2 along the axial direction. If the power supply module 3 needs to be replaced, the user only needs to remove the power supply module 3 to be replaced from the shell 2 along the axial direction Y from the first opening 2.1, and then let the replaced power supply module 3 enter the shell 2 along the axial direction Y from the first opening 2.1. This replacement method is convenient and quick, and will not cause any damage to other components in the aerosol generating device 1.

[0051] Further, combined with Figure 2-Figure 3 In the above embodiment, the power supply module 3 has a first end 3.1 and a second end 3.2 arranged opposite to each other along the axial direction Y, and the first end 3.1 enters the shell 2 from the first opening 2.1; further, the side wall 3.2.1 of the second end 3.2 is tightly matched with the inner wall 2.2 of the shell 2. Preferably, the width of the power supply module 3 gradually increases from the first end 3.1 to the second end 3.2, that is, the shape of the power supply module 3 is narrow at the top and wide at the bottom. For example, the width w1 of the power supply module 3 is less than w2.

[0052] In the process of the power supply module 3 entering the housing 2 from the first opening 2.1 along the axial direction Y, since the upper end of the power supply module 3 is narrow, there is a certain gap between it and the inner wall 2.2 of the housing 2, and the gap is relatively large (see Figure 7 ), thereby making it easier for the power supply module 3 to enter the housing. The lower end of the power supply module 3 is wider, and the gap between the side wall 3.2.1 of the second end 3.2 and the inner wall 2.2 of the housing 2.2 is smaller (see Figure 8 ). As a result, when the power supply module 3 is connected in place, the side wall 3.2.1 of the second end 3.2 of the power supply module and the inner wall 2.2 of the housing 2 fit tightly together, thereby securing the power supply module 3 within the housing 2. It should be noted that "connected in place" means that the power supply module 3 enters a predetermined position in the aerosol generating device 1, thereby achieving a reliable electrical connection. Generally speaking, only after the power supply module 3 is connected in place will the circuit of the aerosol generating device 1 be closed, and the power supply module 3 will begin to power the aerosol generating device 1, thereby generating aerosol for the user to inhale.

[0053] Further, if Figure 4As shown, the width of at least a portion of the second end 3.2 of the power supply module 3 is slightly larger than the inner diameter of the housing 2. This generates a clamping force, forming an interference fit, which tightly secures the power supply module 3 within the housing 2. The clamping force generated by the interference fit increases the static friction between the power supply module 3 and the housing 2, helping to stabilize the power supply module 3 and prevent it from moving or falling off during use.

[0054] The utility model designs the structure of the power supply module 3 and sets it into a structure that is narrow at the top and wide at the bottom. The first end 3.1 of the power supply module 3 is loosely matched with the inner wall 2.2 of the shell 2, and the second end 3.2 is tightly matched with the inner wall 2.2 of the shell 2, thereby ensuring the smooth entry and removal of the power supply module 3. After being connected in place, it can also limit the power supply module 3 along the radial direction X (for example, Figure 1 and Figure 4 The X direction in the figure, where the X direction is perpendicular to the Y direction) moves.

[0055] Further, if Figure 2-Figure 3 and Figure 5 As shown, the power supply module 3 includes a housing 4, which is provided along the width direction of the power supply module 3 (eg Figure 1 and Figure 4 The outer wall 4.1 is preferably an inclined surface inclined relative to the insertion direction Y1 (e.g., Y1 in the figure) of the power supply module 3, extending from the second end 3.2 to the first end 3.1, and the inclined surface extends from the second end 3.2 to the first end 3.1 in the direction (e.g., Figure 5 The M direction in the figure forms an included angle α with the insertion direction Y1 of the power supply module 3. The included angle α satisfies the following conditions: 0.2°≤α≤10°. Setting the angle α within this range facilitates inserting the power supply module 3 into the housing 2. Furthermore, once properly connected, the power supply module 3 has a strong static friction force with the housing 2, effectively preventing the power supply module 3 from moving in the radial direction X or falling off in the axial direction Y.

[0056] Further, if Figure 1-Figure 3As shown, the power supply module 3 also includes a base 5, which has a convex edge 5.1, which abuts against the first opening 2.1. The convex edge 5.1 can serve as a stopper, positioning and protection device, and can also facilitate the user to remove the power supply module 3 from the shell 2. Specifically, on the one hand, the convex edge 5.1 abuts against the first opening 2.1 of the shell 2, which can ensure that the power supply module 3 is accurately placed in the predetermined position (i.e., connected in place) during the entry process, preventing the power supply module 3 from shifting during use. On the other hand, after the convex edge 5.1 abuts against the first opening 2.1 of the shell 2, a seal can be formed, thereby preventing external dust, liquid or other foreign matter from entering the interior of the electronic cigarette, thereby protecting the internal circuits and components. On the other hand, when the user installs or removes the power supply module 3, the convex edge 5.1 can serve as a grip, providing the user with a force point, making it easier for the user to apply force, so that the power supply module 3 can be quickly removed from the shell 2.

[0057] Further, if Figure 1 As shown, the aerosol generating device 1 further includes a first control unit 6, which is fixed in the shell 2 and is used to control the power supply module 3 to power the aerosol generating device 1 to generate aerosol for the user to inhale. The power supply module 3 and the first control unit 6 are detachably connected.

[0058] In existing e-cigarettes, the power supply module is often soldered to the circuit board (control unit) via wires. If the battery needs to be replaced, it is often necessary to replace it together or disassemble the circuit board and battery. However, this disassembly is often destructive and cannot be restored once disassembled (the battery and control board wires are soldered). Even if reassembled, problems with oil sealing and airtightness are likely to occur.

[0059] Based on this, the utility model designs the power supply module 3 and the first control unit 6 as two independent modules. For example, the first control unit 6 is fixed in the shell 2, and the power supply module 3 and the first control unit 6 are designed to be detachably connected. If the power supply module 3 fails, the user only needs to remove the power supply module 3 alone to repair or replace the power supply module 3 in time.

[0060] Further, if Figure 1As shown, the power supply module 3 also includes a first magnetic body 7, which can be provided at the top of the power supply module 3 (i.e., the first end 3.1), and the first control unit 6 includes a second magnetic body 8, which can be provided at the bottom end of the control unit 3, wherein the top and the bottom are arranged relative to each other along the axial direction Y, the first magnetic body 7 and the second magnetic body 8 are arranged relative to each other along the axial direction Y, and the power supply module 3 and the first control unit 6 are detachably connected by magnetic attraction. This connection method is stable and reliable, and the user can easily assemble or disassemble the power supply module 3 and the shell 2 without the aid of any tools. In addition, by achieving connection through magnetic attraction, the connection structure can be designed to be more compact, and no additional space is required to accommodate a complex connection mechanism, which is particularly suitable for disposable electronic cigarettes and small electronic cigarettes with replaceable cartridges with limited space.

[0061] Further, combined with Figure 6 , a groove is provided at the top of the power supply module 3, and the power supply module 3 also includes an elastic button 9, which is located in the groove. A protrusion 10 is provided at the bottom end of the first control unit 6, and the protrusion 10 abuts against the elastic button 9 along the axial direction Y. The cooperation between the elastic button 9 and the protrusion 10 helps to accurately align the power supply module 3 and the first control unit 6 during the assembly process, that is, when the protrusion 10 abuts against the elastic button 9 along the axial direction Y, the power supply module 3 is connected in place. In addition, arranging the elastic button 9 in the groove can effectively prevent users from touching it by mistake. In other words, the elastic button 9 will only be triggered and the aerosol generating device 1 will start working only when the user presses it intentionally.

[0062] Furthermore, a second magnetic body 8 is provided at the bottom end of the first control unit 6, a metal sheet is provided at the top end of the power supply module 3, and a Hall sensor is provided at the bottom end of the metal sheet. The Hall sensor is used to detect changes in the magnetic field and generate an electrical signal to the first control unit 6. Specifically, the Hall sensor can detect changes in the magnetic field near the metal sheet. When the first control unit 6 is close to or separated from the power supply module 3, the magnetic field environment in which the power supply module is located will change, and the Hall sensor can capture these changes. After the Hall sensor detects the change in the magnetic field, it will generate a corresponding electrical signal. These electrical signals can be received by the first control unit 6 and can determine whether the power supply module 3 is connected in place, that is, whether the power supply module 3 and the first control unit 6 are correctly connected. When the connection is in place, the electrical signal reaches a threshold and remains stable. With this arrangement, it is possible to accurately and quickly determine whether the connection is in place.

[0063] Further, if Figure 1 As shown, the shell 2 further comprises a second opening 2.3, which is located at the other end of the shell 2 along the axial direction Y. The aerosol-generating article can be inserted into or removed from the shell 2 along the axial direction Y from the second opening 2.3.

[0064] The aerosol-generating product includes an aerosol-generating matrix, which is a material that can provide volatile components when heated. The aerosol-generating matrix can be solid or liquid. The aerosol-generating matrix can also be a paste-like material, a small bag of porous material including an aerosol-generating matrix, or loose tobacco mixed with a gelling agent or adhesive, which may contain common atomizers such as glycerol. Alternatively, the aerosol-generating matrix can include tobacco-containing material or non-tobacco material, or it can contain both tobacco material and non-tobacco material. The aerosol-generating matrix also includes an atomizer, such as glycerol or propylene glycol. The aerosol-generating matrix can also include additional ingredients, such as nicotine or flavor extracts. For a solid aerosol-generating matrix, it can be formed into a structure of a cigarette cartridge or a cigarette stick to be contained in a smoking device, and further made into the form of a heated cigarette, which will also include a tobacco matrix part and a filter part.

[0065] In this embodiment, the aerosol-generating product is an example of a cigarette cartridge 11 containing cigarette oil, wherein the cigarette cartridge 11 is detachable relative to the shell 2, so that the user can take out the cigarette cartridge 11 at any time as needed to replace the cigarette oil, and then embed the cigarette cartridge 11 into the shell 2 along the axial direction Y from the second opening 2.3.

[0066] Further, if Figure 1 As shown, the first control unit 6 includes a third magnetic body 12, which is located at the top of the first control unit 6. The cigarette cartridge 11 also includes a fourth magnetic body 18, which is located at the bottom of the cigarette cartridge 11. The third magnetic body 12 and the fourth magnetic body 18 are arranged opposite each other along the axial direction Y. The cigarette cartridge 11 and the first control unit 6 are detachably connected by magnetic attraction. This connection method is stable and reliable.

[0067] In particular, Figure 1 and Figure 4 As shown, the first control unit 6 is fixed in the shell 2, and the cigarette cartridge 11 and the power supply module 3 are both detachable relative to the shell 2 and the first control unit 6. The utility model designs the first control unit 6, the cigarette cartridge 11 and the power supply module 3 into three independent modules, so that when any module fails or needs to be replaced, it can be quickly disassembled and installed without the help of any external tools. Among them, when the three modules are assembled together, the first magnetic body 7 at the upper end of the power supply module 3 and the second magnetic body 8 at the bottom end of the first control unit 6 are connected by magnetic attraction, and the lead 15 in the power supply module 3 (the wire connecting the battery 19 and the electrode column 16) is wrapped inside the electrode column 16. This design can protect the lead 15 and prevent it from being damaged by external factors. Afterwards, the electrode column 16 of the power supply module 3 contacts the spring pin 17 of the first control unit 6, thereby establishing a circuit connection and providing the necessary power for the electronic cigarette.

[0068] It should be noted that the power supply module 3 houses a battery 19, typically a rechargeable lithium-ion battery. The first control unit 6 comprises a main control PCB board and integrated circuitry connecting the battery, microphone sensor, and heating element of the atomization unit. When a user draws on the e-cigarette, the airflow triggers the microphone sensor, detecting the puff. Once the puff is detected, the microphone sensor sends a signal, and the first control unit 6 activates the heating element within the e-cigarette. Once heated, the heating element atomizes the nicotine and flavoring solution in the cartridge 11 into vapor particles for the user to inhale.

[0069] Further, if Figure 1 As shown, the power supply module 3 includes a charging unit and a power supply unit. The charging unit is used to charge external power devices, and the power supply unit is used to power the aerosol generating device 1. In other words, the power supply module 3 provided by the present invention can not only power the aerosol generating device 1, but also serve as a charging device to charge external power devices such as headphones. Because the power supply module 3 of the present invention can be tightly fixed within the housing 2, it can support a large-capacity battery. In other words, the battery 19 in the power supply module 3 can be a large-capacity battery.

[0070] Furthermore, the power supply unit and the charging unit are respectively equipped with interfaces. Specifically, the power supply unit and the charging unit are respectively equipped with a charging interface and a power supply interface, and the charging interface is used to connect an external power device (such as headphones, mobile phones, etc.) to charge the external power device. The power supply interface is used to connect an adapter, and the adapter supplies power to the power supply module through the power supply interface, and the power supply module supplies power to the aerosol generating device. With this arrangement, the power supply module 3 can not only charge the external power device, but also supply power to the aerosol generating device 1, thereby reducing the number of items that the user needs to carry when going out and improving portability.

[0071] Further, if Figure 4 As shown, the power supply unit and the charging unit share a single interface 13. This interface 13 is a charging interface used to connect to an external power device for charging. It is also used to connect to an adapter, which powers the power supply module through the charging interface. Designing interface 13 as a single interface saves operating space and also makes the product design more concise and beautiful.

[0072] Further, if Figure 4 As shown, the power supply module 3 also includes a second control unit 14, which includes a protection circuit for protecting the power supply module 3. For example, when the battery is overcharged, over-discharged, or short-circuited, the circuit is promptly disconnected to protect the power supply module 3. The second control unit 14 can control the interface to supply power to the power supply module and control the charging unit to supply power to external power devices.

[0073] Reference Figure 9 Combined with Figure 1 The present invention also provides a control method for an aerosol generating device, which can be applied to the aerosol generating device 1 in each of the above embodiments. For example, the aerosol generating device 1 includes a power supply module 3 and a housing 2. The power supply module 3 is used to power the aerosol generating device 1 to generate aerosol for the user to inhale. The housing 2 has a first opening 2.1. The first opening 2.1 is located at one end of the housing 2 along the axial direction Y. The power supply module 3 is detachably connected to the housing 2. The power supply module 3 enters the housing 2 along the axial direction from the first opening 2.1 and can be removed from the housing 2. The control method includes:

[0074] Connection status information acquisition step S1: acquiring connection status information between the power supply module and the aerosol generating device.

[0075] Preset condition determination step S2: determining whether the connection status information satisfies a first preset condition.

[0076] If the first preset condition is met, step S3 is performed: obtaining the power supply parameters of the power supply module. Then, a second determination step S5 is performed: determining whether the power supply parameters of the power supply module are within a preset range for normal use of the aerosol generating device. If so, step S6 is performed: controlling the power supply module to supply power to the aerosol generating device. If not, step S7 is performed: controlling the power supply module to not supply power to the aerosol generating device. The power supply parameters may be voltage, current, and / or temperature, and accordingly, the preset range may be a preset range of voltage, current, and / or temperature.

[0077] If the first preset condition is not met, step S4 is performed: controlling the power supply module to stop supplying power to the aerosol generating device.

[0078] Among them, the first preset condition is that the power supply module is connected in place.

[0079] By adopting the above technical solution, it can be ensured that only when "the power supply module is connected in place and the power supply parameters of the power supply module are within the preset range under the normal use state of the aerosol generating device" are simultaneously met, the power supply module can supply power to the aerosol generating device and generate aerosol for the user to inhale. That is, when the power supply module is not connected in place or the power supply parameters are abnormal, the power supply module will not supply power to the aerosol generating device, nor will it generate aerosol for the user to inhale. The significance of such a design is that, on the one hand, when it is not connected in place, the battery fails, or the battery model does not match the aerosol generating device, it can serve as a reminder to inform the user that the device needs to be checked or the battery replaced. On the other hand, it can also effectively prevent damage to the user or the device due to abnormal power supply parameters (for example, the voltage is too high or too low) or the power supply module is turned on when it is not connected in place. It should be noted that not being connected in place means that a reliable electrical connection has not been established between the power supply module and the aerosol generating device or no electrical connection has been established.

[0080] Furthermore, in each of the above embodiments, the power supply module includes a charging unit, which is used to charge external electrical devices, such as Figure 10 As shown, the preset condition judgment step S2 also includes: if the first preset condition is met, step S3 is performed: obtaining the power supply parameters of the power supply module, and at the same time turning off the charging unit so that the charging unit cannot charge the external electrical device. Since the aerosol generating device usually uses a lithium battery, if the power supply module is connected in place, it can not only serve as a charging device to power the external electrical device, but also power the aerosol generating device to generate aerosol for the user to inhale. The battery may be under greater pressure, which may increase the risk of overheating, short circuit or even explosion. Based on this, while obtaining the power supply parameters of the power supply module, turning off the charging unit so that the charging unit cannot charge the external electrical device can effectively avoid the above risks. Furthermore, the external power supply can charge the power supply module. That is to say, if the power supply module is connected in place, the external power supply can charge the power supply module, and at the same time, the power supply module can also power the aerosol generating device to generate aerosol for the user to inhale.

[0081] Further, if Figure 11 As shown, the power supply module includes a charging unit, which is used to charge external electrical equipment. When the connection status information does not meet the first preset condition, after the preset condition judgment step S2, it also includes: step S8 of judging whether the second preset condition is met.

[0082] If the second pre-set condition is met, step S9 proceeds to the following: the charging unit is turned on to enable the charging unit to charge the external electrical device. The second pre-set condition is that the power supply module is completely disconnected from the aerosol generating device. Complete electrical disconnection means that the power supply module and the aerosol generating device are not in electrical contact. Under this condition, the power supply module can be partially or completely removed from the housing. This design ensures that the power supply module can only charge the external electrical device after it is completely removed from the housing. This prevents the heat generated during the charging process from affecting the internal components of the aerosol generating device, thereby helping to extend the service life of the aerosol generating device.

[0083] Further, if Figure 11 As shown, if the second preset condition is not met, step S10 is performed: the power supply unit is turned off so that the power supply unit cannot supply power to the aerosol generating device, and the charging unit is turned off so that the charging unit cannot charge the external power device. In other words, as long as the power supply module and the aerosol generating device are in a partially separated state, the power supply module can neither supply power to the aerosol generating device nor serve as a charging device to charge the external power device. This can prevent the aerosol generating device from being accidentally activated due to improper operation by the user (for example, the power supply module is not properly connected or accidentally touched), thereby avoiding accidental power supply and reducing the risk of short circuits and electrical fires.

[0084] Further, for Figure 6 The aerosol generating device in the embodiment of the present invention, for example, the aerosol generating device 1 further includes a first control unit 6, which is fixed in the shell 2 and is used to control the power supply module 3 to power the aerosol generating device 1 to generate aerosol for the user to inhale. The power supply module 3 is detachably connected to the first control unit 6, and a groove is provided at the top of the power supply module 6. The power supply module 3 further includes an elastic button 9, which is located in the groove. A protrusion 10 is provided at the bottom end of the first control unit 6, and the protrusion 10 and the elastic button 9 are arranged opposite to each other along the axial direction Y.

[0085] Determining whether the connection status information satisfies the first preset condition includes detecting whether the protrusion 10 and the elastic button 9 are in contact. If so, the connection status information satisfies the first preset condition. The present invention determines whether the first preset condition is met, i.e., whether the connection is in place, by detecting whether the protrusion 10 and the elastic button 9 are in contact. Because the elastic button 9 is within the recess, accidental user contact is avoided. This detection method is fast and accurate.

[0086] Furthermore, the aerosol generating device also includes a first control unit, which is fixed in the housing and is used to control the power supply module to power the aerosol generating device to generate aerosol for the user to inhale. The power supply module is detachably connected to the first control unit. A second magnetic body is provided at the bottom end of the first control unit, a metal sheet is provided at the top end of the power supply module, and a Hall sensor is provided at the bottom end of the metal sheet. The Hall sensor is used to detect changes in the magnetic field and generate an electrical signal to the first control unit.

[0087] Determining whether the connection status information satisfies the first preset condition includes: acquiring an electrical signal and determining whether the electrical signal reaches a threshold and remains unchanged; if so, the connection status information satisfies the first preset condition.

[0088] As the power supply module is inserted into the housing axially from the first opening, the distance between the power supply module and the first control unit becomes smaller and smaller, and the magnetic field environment in which the power supply module is located becomes stronger and stronger. When the metal sheet at the top of the power supply module 3 and the magnetic material at the bottom of the control unit are completely attached through magnetic attraction, the magnetic field reaches the threshold and then no longer changes. The Hall sensor can instantly detect the change in the magnetic field and quickly transmit the information to the first control unit. When the electrical signal reaches the threshold and remains unchanged for a period of time, it is determined that the connection is in place. This design is simple and reliable, and can quickly detect whether the connection is in place and respond quickly.

[0089] Further, if Figure 12 As shown, the power supply module also includes a power supply unit, which is used to power the aerosol generating device. The control method also includes: executing step S01: receiving a power supply instruction from the user, and then performing step S1: obtaining connection status information and step S2: preset condition judgment step to determine whether to power the aerosol generating device.

[0090] That is, after the power supply module is embedded in the housing, the user can give instructions by pressing a button or connecting a Bluetooth phone, and based on the instructions, the connection status information between the power supply module and the housing and the preset conditions are determined. Furthermore, after the power supply module is embedded in the housing, the user can also control the external power supply to power the power supply module by pressing a button or connecting a Bluetooth phone.

[0091] Further, if Figure 13 As shown, the control method further includes: executing step S02: receiving a charging instruction from the user, and then performing step S11: activating the charging unit based on the charging instruction to charge the external power device. This allows the user to use the power supply module as a charging device to charge the power device according to their needs. Furthermore, when the charging unit is activated to charge the external power device, the power supply module's power supply parameters, such as voltage, can be detected to determine whether they are within a preset range. Only within the preset range can the power supply module charge the external power device. This design can prevent battery damage due to over-discharge.

[0092] Reference Figure 14 Combined with Figure 1 The present invention further discloses a control device 20 for an aerosol generating device, wherein the aerosol generating device 1 includes a power supply module 3 and a housing 2. The power supply module 3 is used to power the aerosol generating device 1 to generate aerosol for the user to inhale. The housing 2 has a first opening 2.1. The first opening 2.1 is located at one end of the housing 2 along the axial direction Y. The power supply module 3 is detachably connected to the housing 2. The power supply module 3 enters the housing 2 from the first opening 2.1 along the axial direction 2 and can be removed from the housing 2.

[0093] The device 20 further comprises: a connection status information acquisition module 20.1, a preset condition judgment module 20.2 and a second judgment module 20.3, wherein the connection status information acquisition module 20.1 is connected to the preset condition judgment module 20.2, and the preset condition judgment module 20.2 is connected to the second judgment module 20.3.

[0094] The connection status information acquisition module 20.1 is used to obtain the connection status information between the power supply module and the aerosol generating device.

[0095] The preset condition judgment module 20.2 is used to judge whether the connection status information meets the first preset condition. If the first preset condition is met, the power supply parameters of the power supply module are obtained. If the first preset condition is not met, the power supply module is controlled not to power the aerosol generating device.

[0096] The second determination module 20.3 is configured to determine whether the power supply parameters of the power supply module are within a preset range under normal use of the aerosol generating device; if so, the power supply module is controlled to supply power to the aerosol generating device; if not, the power supply module is controlled not to supply power to the aerosol generating device;

[0097] Among them, the first preset condition is that the power supply module is connected in place.

[0098] Furthermore, the preset condition judgment module 20.2 is also used to determine if the first preset condition is met, obtain the power supply parameters of the power supply module, and at the same time turn off the charging unit so that the charging unit cannot charge the external power device.

[0099] Furthermore, if the first preset condition is determined not to be satisfied, the preset condition determination module 20.2 is further configured to determine whether a second preset condition is satisfied. If the second preset condition is satisfied, the charging unit is activated to enable the charging unit to charge the external electrical device. The second preset condition is that the electrical contact between the power supply module and the aerosol generating device is completely disconnected.

[0100] Furthermore, the preset condition judgment module 20.2 is also used to judge: if the second preset condition is not met, the power supply unit is turned off so that the power supply unit cannot power the aerosol generating device, and the charging unit is turned off so that the charging unit cannot charge the external electrical device.

[0101] Furthermore, in the above embodiment, the connection status information obtaining module 20.1 is further configured to determine whether the first preset condition is satisfied by detecting whether the protrusion is in contact with the elastic button. If so, the connection status information satisfies the first preset condition.

[0102] Furthermore, in the above embodiment, the connection status information acquisition module 20.1 is further configured to acquire the electrical signal and determine whether the electrical signal reaches a threshold and remains unchanged. If so, the connection status information satisfies the first preset condition.

[0103] Furthermore, in the above embodiment, if Figure 15 As shown, the control device 20 of the aerosol generating device further includes: a module 20.4 for receiving a power supply instruction from a user, wherein the module 20.4 for receiving a power supply instruction from a user is connected to the connection status information obtaining module 20.1.

[0104] The module 20.4 for receiving the power supply instruction from the user is used to receive the power supply instruction from the user, and then perform a connection status information acquisition step and a preset condition judgment step to determine whether the power supply module supplies power to the aerosol generating device.

[0105] Furthermore, in the above embodiment, if Figure 16 As shown, the control device 20 of the aerosol generating device further includes: a module 20.5 for receiving a charging instruction from a user, wherein the module 20.5 for receiving a charging instruction from a user is used to receive a charging instruction from a user and activate a charging unit based on the charging instruction to charge an external electrical device.

[0106] Furthermore, the connection status information acquisition module 20.1, the preset condition judgment module 20.2, the second judgment module 20.3, the user's power supply instruction receiving module 20.4, and the charging instruction module 20.5 can be set in the first control unit and / or the second control unit.

[0107] Further, if Figure 17 As shown, the present invention further provides an electronic device 21, which includes a processor 21.2 and a memory 21.1. The memory 21.1 stores at least one instruction, which, when executed by the processor 21.2, implements the control method described in any of the above embodiments. The memory 21.1 may include, for example, a system memory, a fixed non-volatile storage medium, etc. The system memory may store, for example, an operating system, an application program, a boot loader, and other programs.

[0108] Using this technical solution, the electronic device 21 ensures that the power supply module can only power the aerosol generating device and generate aerosol for the user to inhale if both the power supply module is properly connected and the voltage of the power supply module matches the voltage of the aerosol generating device under normal use. In other words, if the power supply module is not properly connected or the voltage is abnormal, the power supply module will not power the aerosol generating device and will not generate aerosol for the user to inhale.

[0109] The present invention also provides a computer-readable storage medium, in which at least one instruction is stored. When the at least one instruction is executed, the control method in any of the above embodiments is implemented.

[0110] Using the above technical solution, the computer-readable medium ensures that the power supply module can only power the aerosol-generating device and generate aerosol for the user to inhale if both the power supply module is properly connected and the voltage of the power supply module matches the voltage of the aerosol-generating device under normal use are met. In other words, if the power supply module is not properly connected or the voltage is abnormal, the power supply module will not power the aerosol-generating device and will not generate aerosol for the user to inhale.

[0111] In another embodiment, the power supply module and the first control unit are inseparable, and when the second control unit of the power supply module detects that the power supply module is supplying power to the aerosol generating device to generate aerosol, the power supply module is prohibited from charging the external power device; when the power supply module is charging the external power device, if the second control unit receives a signal from the first control unit indicating that power should be supplied to the aerosol generating device to generate aerosol, the power supply module stops charging the external power device. Preferably, the control unit includes a first control unit and a second control unit.
