In this way, when the battery 24 module 2 is damaged, it is only necessary to remove the battery 24 module 2 from the atomizing module 1, and then assemble a new battery 24 module 2 on the first side wall 113 of the atomizing module 1 so that the aerosol generating device can continue to be used without replacing the entire aerosol generating device, thereby reducing the user's usage cost.

[0055] In this embodiment, it can be understood that when the atomizer module 1 is damaged, it is only necessary to detach the atomizer module 1 from the battery 24 module 2, and then assemble a new atomizer module 1 on the second side wall 213 of the battery 24 module 2 so that the aerosol generating device can continue to be used without replacing the entire aerosol generating device.

[0057] In this embodiment, it should be noted that, in specific implementation, the detachable connection between the first connector 13 and the second connector 23 may be a snap connection, a plug-in connection, a magnetic connection, etc., as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this. It can be understood that, in some optional embodiments, when the detachable connection between the first connector 13 and the second connector 23 is a snap connection, the structural form of the first connector 13 may be a snap, and accordingly, the structural form of the second connector 23 is a slot that can be engaged with the snap; in other optional embodiments, when the detachable connection between the first connector 13 and the second connector 23 is a plug-in connection, the structural form of the first connector 13 may be a plug, and accordingly, the structural form of the second connector 23 is a socket that can be plugged with the plug; in some other optional embodiments, such as Figure 2-3 、 Figure 6 as well as Figure 8-9 As shown, when the detachable connection between the first connecting member 13 and the second connecting member 23 is a magnetic connection, the first connecting member 13 includes at least one first magnetic member 131 fixed on the first side wall 113, and the second connecting member 23 includes at least one second magnetic member 231 fixed on the second side wall 213. The at least one first magnetic member 131 and the at least one second magnetic member 231 attract each other. In a specific implementation, at least one of the first magnetic member 131 and the second magnetic member 231 is a magnet. For example, both the first magnetic member 131 and the second magnetic member 231 are magnets. For another example, one of the first magnetic member 131 and the second magnetic member 231 is a magnet, and the other is a magnetic body made of a magnetic conductive material (for example, a magnetic conductive material such as iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as it can meet the use requirements, this embodiment does not impose specific restrictions on the structural form of the first magnetic member 131 and the second magnetic member 231.

[0058] Furthermore, in some optional embodiments of the present application, in order to achieve reliable electrical contact between the first electrode assembly 12 and the second electrode assembly 22, the first electrode assembly 12 may be in the form of a conductive nail, and the second electrode assembly 22 may be in the form of a conductive spring pin. Figure 6 as well as Figure 8-9As shown, the first electrode assembly 12 includes two first conductive nails 121 spaced apart, and the second electrode assembly 22 includes two first conductive elastic pins 221 spaced apart. The two first conductive nails 121 are in electrical contact with the two first conductive elastic pins 221 in a one-to-one correspondence. In this embodiment, it can be understood that the two conductive nails of the atomization module 1 can be regarded as the positive and negative electrodes of the atomization module 1, and the two conductive elastic pins of the battery module 24 can be regarded as the positive and negative electrodes of the battery module 24. In addition, it can be understood that the conductive nails are a type of electrode that does not have a telescopic function, and the conductive elastic pins are a type of electrode that can be telescopic. The specific structural composition of the conductive elastic pins is well known to those skilled in the art and will not be repeated here.

[0060] Further, please refer to Figure 1-3 In some optional embodiments of the present application, a boss portion 110 is provided on the side of the atomizer module 1 facing the battery 24 module 2, and an end surface of the boss portion 110 facing the battery 24 module 2 is a first side wall 113 of the atomizer module 1. A groove 210 adapted to the boss portion 110 is provided on the side of the battery 24 module 2 facing the atomizer module 1. The second side wall 213 of the battery 24 module 2 is located in the groove 210 and is arranged opposite to the notch of the groove 210. The boss portion 110 and the groove 210 are arranged in coordination with each other. In this way, the mutual coordination between the boss portion 110 and the groove 210 can limit the movement of the battery 24 module 2 relative to the atomizer module 1 in the up-down direction or the front-back direction of the aerosol generating device, thereby facilitating the improvement of the connection stability between the atomizer module 1 and the battery 24 module 2.

[0061] Furthermore, in some optional embodiments of the present application, the specific structural forms of the atomization module 1 and the power supply module can be as follows:

[0062] Please refer to Figure 1-4The atomization module 1 includes a first shell 11, an atomization core 14, a mouthpiece 15, and a first control circuit board 16 installed in the first shell 11. The first shell 11 has a first end face 111 and a second end face 112 along its height direction. The first shell 11 has a first side wall 113 along its circumference. A first airway 101 and a storage cavity 102 for storing aerosol-forming substances are provided in the first shell 11. The mouthpiece 15 is connected to the first end face 111 of the first shell 11 and is communicated with the air outlet end of the first airway 101. When a user bites the mouthpiece 15 to inhale, the airflow in the first airway 101 can be An inhalation airflow is formed on the flow path; the atomizer core 14 is installed on the airflow flow path of the first airway 101, so that the aerosol generated by the atomizer core 14 can be carried away by the inhalation airflow formed in the first airway 101 and discharged to the outside for inhalation by the user. Moreover, the atomizer core 14 is connected to the storage chamber 102, so that the atomizer core 14 can absorb aerosol-forming substances from the storage chamber 102 for heating and atomization; the first control circuit board 16 is electrically connected to the atomizer core 14 and the first electrode assembly 12 respectively through wires or the like, and the first control circuit board 16 can control the on-off between the atomizer core 14 and the first electrode assembly 12;

[0063] The battery 24 module 2 includes a second shell 21 and a battery 24 installed in the second shell 21. The second shell 21 has a third end face 211 and a fourth end face 212 along its own height direction. The second shell 21 has a second side wall 213 along its own circumference. The battery 24 is electrically connected to the second electrode assembly 22.

[0064] In this embodiment, based on the above structural design, the structural principle of the aerosol generating device provided in this embodiment is as follows:

[0065] During use, the user can trigger the first control circuit board 16 by pressing the switch button (the switch button can be exposed and arranged on the outer surface of the first shell 11 and is electrically connected to the first control circuit board 16) to control the atomization core 14 to connect to the first electrode assembly 12, so that the battery 24 can provide electrical energy to the atomization core 14 through the second electrode assembly 22 and the first electrode assembly 12. The atomization core 14 is energized and heated to atomize the aerosol-forming substance adsorbed by itself into an aerosol that can be inhaled by the user. When the user bites the mouthpiece 15 to inhale, an inhalation airflow is formed on the airflow flow path of the first airway 101. When the inhalation airflow flows through the atomization core 14, the aerosol is taken away. The aerosol eventually flows out of the mouthpiece 15 to the user's mouth along with the inhalation airflow and is inhaled by the user.

[0066] In this embodiment, it should be noted that the specific structural composition, operating principle, and communication method between the atomizer core 14 and the storage chamber 102 are all well known to those skilled in the art and will not be described in detail here. In addition, in a specific implementation, the first shell 11 can be a one-piece structure or a split structure assembled from different shell structures. Similarly, the second shell 21 can be a one-piece structure or a split structure assembled from different shell structures. The specific structural form of the first shell 11 and the second shell 21 can be determined according to actual use needs, and this embodiment does not impose specific restrictions on this. In addition, in a specific implementation, the structural form of the first control circuit board 16 can be a single-chip microcomputer, processor, controller, or other mature device with control functions in the field.

[0067] Further, please refer to Figure 4 In some optional embodiments of the present application, the atomization module 1 further includes a first airflow sensor 17 mounted within the first housing 11. The first airflow sensor 17 is located in the airflow path of the first airway 101 and is electrically connected to the first control circuit board 16. The air inlet end 1011 of the first airway may be disposed on the second end surface 112 of the second housing 21. In this embodiment, the provision of the first airflow sensor 17 enables the aerosol generating device to operate more intelligently, thereby improving the user experience. Specifically, when the user bites the mouthpiece 15 and takes a puff, an inhalation airflow is formed on the airflow path of the first airway 101. This inhalation airflow triggers the first airflow sensor 17 to operate, causing the first airflow sensor 17 to send a puff signal to the first control circuit board 16 to indicate that the user is taking a puff. When the first control circuit board 16 receives the puff signal, the first control circuit board 16 controls the atomizer core 14 to connect to the first electrode assembly 12, thereby causing the atomizer core 14 to be powered on and heated, and atomizing the aerosol-forming substance drawn from the storage chamber 102 into an aerosol that can be inhaled by the user. When the user stops taking a puff, no inhalation airflow is formed on the airflow path of the first airway 101, causing the first airflow sensor 17 to send a stop signal to the first control circuit board 16 to indicate that the user has stopped taking a puff. When the first control circuit board 16 receives the stop signal, the first control circuit board 16 disconnects the electrical connection between the atomizer core 14 and the first electrode assembly 12, thereby powering off the atomizer core 14 and stopping the atomization operation.

[0068] In some other optional embodiments of the present application, the specific structural forms of the atomization module 1 and the power supply module can be as follows:

[0069] Please refer to Figure 5-9The atomization module 1 includes a first shell 11, an atomization core 14 and a mouthpiece 15. The first shell 11 has a first end face 111 and a second end face 112 along its height direction, and a first side wall 113 along its circumference. A first air channel 101 and a storage cavity 102 for storing aerosol-forming substances are provided in the first shell 11. The mouthpiece 15 is connected to the first end face 111 of the first shell 11 and communicates with the air outlet end of the first air channel 101 (in some optional embodiments, the air inlet end 1011 of the first air channel can be provided on the second end face 112 of the first shell 11). The atomization core 14 is installed on the airflow path of the first air channel 101 and communicates with the storage cavity 102. The first electrode assembly 12 is electrically connected to the atomization core 14 by means of a wire or the like.

[0070] The battery 24 module 2 includes a second shell 21, a battery 24 and a second control circuit board 25. The second shell 21 has a third end face 211 and a fourth end face 212 along its own height direction. The second shell 21 has a second side wall 213 along its own circumference. The battery 24 is installed in the second shell 21 and is electrically connected to the second control circuit board 25 through wires or the like. The second control circuit board 25 is installed in the second shell 21 and is electrically connected to the second electrode assembly 22 through wires or the like.

[0071] In this embodiment, based on the above structural design, the structural principle of the aerosol generating device provided in this embodiment is as follows:

[0072] During use, the user can trigger the second control circuit board 25 by pressing a switch button (the switch button can be exposed and arranged on the outer surface of the second shell 21 and is electrically connected to the second control circuit board 25), so that the battery 24 can provide electrical energy to the atomization core 14 through the second electrode assembly 22 and the first electrode assembly 12. The atomization core 14 is energized and heated to atomize the aerosol-forming substance adsorbed by itself into an aerosol that can be inhaled by the user. When the user bites the mouthpiece 15 to inhale, an inhalation airflow is formed on the airflow flow path of the first airway 101. When the inhalation airflow flows through the atomization core 14, the aerosol is taken away. The aerosol eventually flows out of the mouthpiece 15 to the user's mouth along with the inhalation airflow and is inhaled by the user.

[0073] In this embodiment, it can be understood that the aerosol generating device provided in this embodiment is similar to the aerosol generating device provided in the embodiment. Figure 1-4 The aerosol generating device provided in the embodiment shown (it should be noted that, in some embodiments, Figure 4The main difference between the two is that the second control circuit board 25 and the charging interface 26 can be removed (the main difference is that the setting position of the control circuit board has changed, that is, the setting position of the control circuit board is transferred from the first shell 11 of the atomization module 1 to the second shell 21 of the battery 24 module 2. The advantage of this change is that it is conducive to further reducing the user's usage cost, because in some actual application scenarios, the service life of the battery 24 module 2 is usually higher than the service life of the atomization module 1.

[0074] Similarly, see Figure 6-9 In some optional embodiments of the present application, in order to improve the intelligence of the aerosol generating device, an airflow sensor may be added to the second housing 21. Specifically, Figure 7 As shown, the battery 24 module 2 also includes a second airflow sensor 28 installed in the second shell 21. A second air duct 201 is also provided in the second shell 21. The second airflow sensor 28 is located on the airflow flow path of the second air duct 201 and is electrically connected to the second control circuit board 25. The air inlet end 1011 of the first air duct is located on the first side wall 113, and the air outlet end 2011 of the second air duct is located on the second side wall 213 and is correspondingly connected to the air inlet end 1011 of the first air duct (in some optional embodiments, the air inlet end of the second air duct 201 may be provided on the fourth end face 212 of the second shell 21). With such a configuration, when the user bites the mouthpiece 15 to inhale, an inhalation airflow will be formed on the airflow flow path connecting the first airway 101 and the second airway 201. The inhalation airflow will trigger the second airflow sensor 28 to operate, so that the second airflow sensor 28 will send a suction signal to the second control circuit board 25 to indicate that the user is inhaling. When the second control circuit board 25 receives the suction signal, the second control circuit board 25 controls the first electrode assembly 12 to connect to the battery 24, so that the atomizing core 14 is energized and heated, and the aerosol-forming substance sucked from the storage chamber 102 is atomized into an aerosol that can be inhaled by the user. When the user stops inhaling, no inhalation airflow is formed on the airflow flow path connecting the first air channel 101 and the second air channel 201, so that the second airflow sensor 28 sends a stop signal to the second control circuit board 25 to indicate that the user has stopped inhaling. When the second control circuit board 25 receives the stop signal, the second control circuit board 25 disconnects the electrical connection between the second electrode assembly 22 and the battery 24, thereby cutting off the power to the atomizer core 14 and stopping the atomization operation.

[0075] Further, please refer to Figure 4 and Figure 7In some optional embodiments of the present application, the battery module 24 further includes a charging port 26 exposed on the fourth end surface 212 of the second housing 21, and the charging port 26 is electrically connected to the second control circuit board 25. With this arrangement, when the battery 24 of the battery module 24 is low or depleted, the user can conveniently charge the battery 24, thereby extending the service life of the battery module 24 and enabling repeated use of the battery module 24. In a specific implementation, the charging port 26 may be a USB port or a Type-C port, which is not specifically limited in this embodiment.

[0076] Further, please refer to Figure 7 and Figure 10 In some optional embodiments of the present application, the battery 24 module 2 also includes a display component 27 for displaying visual information. The display component 27 is installed on any outer surface of the second shell 21 except the second side wall 213 (such as the upper end surface, front side wall, rear side wall, right side wall, etc. of the second shell 21 that can be easily observed by the user), and the display component 27 is electrically connected to the second control circuit board 25.

[0077] In this embodiment, by adding a display component 27 for displaying visual information on the second shell 21, the user can intuitively observe visual information such as the working parameters of the aerosol generating device. For example, the display component 27 can display visual information such as the remaining power of the battery 24, the operating temperature of the battery 24, the output power of the battery 24, the remaining amount of aerosol-forming material in the storage cavity 102, and preset animation patterns, which is conducive to improving the user experience.

[0078] In this embodiment, it should be noted that, in specific implementation, the structural form of the display component 27 can be a flexible bendable display screen (such as a flexible OLED (organic light-emitting diode) touch screen, a flexible AMOLED (active matrix organic light-emitting diode) touch screen, etc.), or a non-flexible rigid display screen (such as an LED flat panel display screen), which can be determined according to actual usage requirements, and this embodiment does not impose specific restrictions on this.

[0079] Furthermore, in some optional embodiments of the present application, the specific arrangement and structural form of the display assembly 27 may be as follows:

[0080] like Figure 7 as well as Figure 9-10As shown, the second shell 21 also has three third side walls 214 located between the third end face 211 and the fourth end face 212 along its circumference, wherein one of the third side walls 214 and the second side wall 213 are arranged back to back with each other along the first direction of the second shell 21, and the remaining two third side walls 214 are arranged back to back with each other along the second direction of the second shell 21. The first direction of the second shell 21, the second direction of the second shell 21, and the height direction of the second shell 21 are perpendicular to each other. Schematically, the first direction of the second shell 21 is Figure 9-10 The left and right directions in the second housing 21 are Figure 9-10 The front-to-back direction of the second housing 21 is Figure 9-10 In the up-down direction, the three third side walls 214 of the second housing 21 are respectively the front side wall, the right side wall and the rear side wall of the second housing 21. Each third side wall 214 can be a flat surface or a curved surface, which is not specifically limited in this embodiment;

[0081] like Figure 7 as well as Figure 10-13 As shown, the display assembly 27 includes a flexible printed circuit board 276 having a circuit track 2763 and at least two flexible display films 271 fixedly connected to the flexible printed circuit board 276. The flexible printed circuit board 276 is provided with at least two first mounting areas 2761 on one side surface along its thickness direction. The at least two first mounting areas 2761 are spaced apart along the length direction of the flexible printed circuit board 276. Each first mounting area 2761 is fixed with a plurality of light-emitting elements 275 electrically connected to the circuit track 2763. The circuit track 2763 is electrically connected to the second control circuit board 25. Each flexible display film 271 covers one first mounting area. 2761, and each flexible display film 271 has a plurality of light-transmitting areas 2711 for allowing light emitted by the light-emitting element 275 to pass through. The area other than the light-transmitting area 2711 in each flexible display film 271 can be regarded as a light-shielding area 2712 through which light cannot pass. The surface of the flexible printed circuit board 276 on the side facing away from the plurality of light-emitting elements 275 can be connected to the second shell 21 by gluing (such as double-sided tape) and covering at least two third side walls 214 of the second shell 21. Among the at least two third side walls 214 covered by the flexible printed circuit board 276, each third side wall 214 corresponds to at least one flexible display film 271.

[0082] In this embodiment, it is understood that the flexible printed circuit board 276, also known as an FPC (Flexible Printed Circuit) board, is a flexible circuit board printed with circuit traces 2763. It has advantages such as good flexibility, light weight, and thinness. In a specific manufacturing process, the desired flexible printed circuit board 276 can be obtained by printing the circuit traces 2763 on a polyimide film or a polyester film. In addition, in some embodiments, the flexible printed circuit board 276 and each flexible display film 271 can be fixedly connected to form a stacked display assembly 27 by bonding with glue (such glue can be double-sided tape, structural adhesive, optically clear adhesive, etc.).

[0083] In this embodiment, it should be noted that, in a specific implementation, the light-emitting element 275 can be a component such as an LED lamp bead that can emit light when powered on, wherein the light-emitting element 275 can be fixed on the surface of the flexible printed circuit board 276 by welding, bonding (such as bonding with insulating glue or conductive glue), etc. and form an electrical connection with the circuit track 2763 of the flexible printed circuit board 276.

[0084] In this embodiment, it should also be noted that, in specific implementation, the material of the flexible display film 271 can be polyimide (PI for short), polyethylene terephthalate (PET for short), polyethylene phthalate (PEN for short), liquid crystal polymer (LCP for short), polyvinyl alcohol (PVA for short), polydimethylsiloxane (PDMS for short) and other flexible materials. As long as they can meet the use requirements, this embodiment does not impose any specific restrictions on the specific material of the flexible display film 271. Among them, in some optional embodiments, when the flexible display film 271 is made of a transparent flexible material, a light-transmitting area 2711 and a light-shielding area 2712 can be formed on the flexible display film 271 by applying light-shielding ink, etc. For example, when the flexible display film 271 is a transparent polyimide film, light-shielding ink can be applied to the surface of the polyimide film in a predetermined manner, and the area of ​​the polyimide film coated with the light-shielding ink can be regarded as the light-shielding area 2712 of the flexible display film 271, and the area of ​​the polyimide film not coated with the light-shielding ink can be regarded as the light-transmitting area 2711 of the flexible display film 271. In other optional embodiments, when the flexible display film 271 is made of an opaque flexible material, a light-transmitting area 2711 and a light-blocking area 2712 can be formed on the flexible display film 271 by laser engraving or the like. For example, when the flexible display film 271 is an opaque PET film, the required light-transmitting area 2711 (the light-transmitting area 2711 is essentially a through hole) can be engraved on the surface of the PET film by laser engraving, and the unengraved area of ​​the PET film is formed as the light-blocking area 2712. Of course, the flexible display film 271 can also be other film structures having light-transmitting areas 2711 and light-blocking areas 2712 that are already mature in the art. For example, in other optional embodiments, the flexible display film 271 can also be a PET color film having light-transmitting areas 2711 and light-blocking areas 2712 that are already mature in the art. As long as it can meet the use requirements, this embodiment does not impose specific limitations on this. In addition, in a specific implementation, the number of light-transmitting areas 2711 on each flexible display film 271 and the shape and size of each light-transmitting area 2711 can be determined according to actual use requirements, and this embodiment does not impose specific restrictions on this. Optionally, as Figure 15-16As shown, the shape of the light-transmitting area 2711 can be a text shape, a number shape, a letter shape, a graphic shape (a dot shape, a line shape), etc. When the light emitted by the light-emitting element 275 reaches the corresponding light-transmitting area 2711, the light display information of the corresponding shape can be displayed. For example, when the light emitted by the light-emitting element 275 reaches the light-transmitting area 2711 in the shape of letters, the user can observe the glowing letters on the surface of the flexible display film 271. In this way, by combining a plurality of light-transmitting areas 2711 of different shapes, light display information of a plurality of different shapes can be obtained, and thus by combining light display information of different shapes, various information of the aerosol generating device can be represented, such as the remaining power of the battery 24, the operating temperature of the battery 24, the output power of the battery 24, the remaining amount of the aerosol-forming substance in the storage cavity 102, a preset animation pattern, etc.

[0085] In the technical solution of this embodiment, the flexible printed circuit board 276 has a plurality of first installation areas 2761 spaced apart along its length direction, and a plurality of light-emitting elements 275 electrically connected to the circuit traces 2763 of the flexible printed circuit board 276 are fixed in each first installation area 2761. Therefore, each first installation area 2761 can be regarded as a light-emitting area. Moreover, each first installation area 2761 is covered by a flexible display film 271 having a plurality of light-transmitting areas 2711. The light emitted by the plurality of light-emitting elements 275 in each first installation area 2761 after being energized can be displayed on the light-transmitting area 2711 of the corresponding flexible display film 271. Therefore, each flexible display film 271 can be regarded as an information display area of ​​the display component 27, thereby realizing the information display function of the display component 27. Since the flexible display film 271 and the flexible printed circuit board 276 are both flexible structures, the display assembly 27 formed by interconnecting the flexible display film 271 and the flexible printed circuit board 276 is also a flexible structure and can be bent. Therefore, when the display assembly 27 is applied to the aerosol generating device, based on the bendable nature of the display assembly 27, the display assembly 27 can be covered along the circumference of the second shell 21 on multiple third side walls 214 of the second shell 21 in different orientations, so that the information display area of ​​the display assembly 27 can be distributed along the circumference of the second shell 21 on at least two outer surfaces in different orientations, thereby increasing the information display range of the aerosol generating device and enabling the aerosol generating device to display more visual information to the user. Moreover, compared to flexible OLED touch screens, flexible AMOLED touch screens, or LED flat-panel displays, the display assembly 27 provided in this embodiment has the advantages of simple structure and low cost.

[0086] In addition, it should be particularly pointed out in the present embodiment that, in some specific implementations, a single piece of flexible display film 271 with a longer length may be used to replace multiple pieces of flexible display film 271 with shorter lengths to simultaneously cover the light-emitting elements 275 in each first installation area 2761. However, in actual practice, the applicant has found that when a single piece of flexible display film 271 with a longer length is used to simultaneously cover the light-emitting elements 275 in each first installation area 2761, it is easy for some of the light-emitting elements 275 to be damaged during the process of installing the display assembly 27 on the multiple third side walls 214 of the second shell 21. The reason for this is that, in the process of wrapping the display assembly 27 of this embodiment around the multiple third side walls 214 of the second shell 21 along the circumference of the second shell 21, it is difficult to avoid bending the display assembly 27 multiple times. In the case where the display component 27 is not installed properly and needs to be reinstalled, the display component 27 needs to be bent more times. Each time the display component 27 is bent, the entire flexible display film 271 will be stretched to varying degrees and local stress concentration will occur. The greater the degree of bending of the display component 27, the greater the degree of stretching of the flexible display film 271 and the more obvious the local stress concentration phenomenon will be. Each time the flexible display film 271 is stretched, the light-emitting element 275 will be squeezed to varying degrees, and the part of the flexible display film 271 where the local stress concentration phenomenon occurs will squeeze the light-emitting element 275 the most. Therefore, when the display component 27 is bent repeatedly, especially when the degree of bending is large, it will easily cause some light-emitting elements 275 to be crushed by the flexible display film 271.

[0087] In order to solve the technical problem that when a single piece of flexible display film 271 with a long length is used to simultaneously cover the light-emitting elements 275 in each first installation area 2761, some of the light-emitting elements 275 are easily damaged during the process of installing the display assembly 27 on the multiple third side walls 214 of the second shell 21, in the technical solution of this embodiment, since each first installation area 2761 is individually covered by a flexible display film 271 with a relatively short length, and each flexible display film 271 is separately arranged rather than being connected to each other into a single-piece film structure, the bending and stretching of each flexible display film 271 are independent of each other and do not affect each other. For example, when the first flexible display film 271 is installed, the first flexible display film 271 is installed. After covering the first third side wall 214 of the second shell 21 (such as the front side wall of the second shell 21), in the process of covering the second third side wall 214 (such as the right side wall of the second shell 21) by bending the display component 27 once, the first flexible display film 271 will not be stretched due to the bending of the display component 27 this time, so that the first flexible display film 271 will not squeeze the light-emitting element 275 opposite to it during this process, thereby effectively reducing the risk of some light-emitting elements 275 being crushed by the flexible display film 271 during the process of installing the display component 27 on multiple third side walls 214 of the second shell 21.

[0088] It should be noted here that in some specific application scenarios, in order to improve the production efficiency of the display component 27, multiple pieces of shorter flexible display film 271 can be obtained by cutting a single piece of longer flexible display film 271. For example, a single piece of longer flexible display film 271 can be used to simultaneously cover the light-emitting elements 275 in each first installation area 2761, and before the display component 27 is installed on the multiple third side walls 214 of the second shell 21, the portion of the single piece of longer flexible display film 271 that does not cover the first installation area 2761 can be cut, so that multiple pieces of shorter flexible display film 271 can be obtained with intervals in the length direction of the display component 27.

[0089] Further, please refer to Figure 11-12 and Figure 14 In some optional embodiments of the present application, the display component 27 further includes at least two flexible diffusion films 272, and a flexible diffusion film 272 is sandwiched between the flexible printed circuit board 276 and each flexible display film 271. The corresponding flexible diffusion film 272 covers each light-transmitting area 2711 of the corresponding flexible display film 271 and covers each light-emitting element 275 in the corresponding first mounting area 2761.

[0090] In this embodiment, a flexible diffuser film 272 is disposed between each first mounting area 2761 of the flexible printed circuit board 276 and each flexible display film 271. While ensuring that the display assembly 27 remains bendable, the corresponding flexible diffuser film 272 can evenly diffuse the light emitted by the light-emitting element 275 within the corresponding first mounting area 2761, allowing the light emitted by the corresponding light-emitting element 275 to be more evenly diffused onto the light-transmitting area 2711 of the corresponding flexible display film 271, thereby improving the uniformity of the light display of the display assembly 27. In a specific implementation, the flexible diffuser film 272 can be a transparent flexible film coated with fluorescent ink (for example, fluorescent ink can be coated on a transparent PET film), or other flexible film with light diffusion function, as long as it meets the requirements of use. This embodiment does not impose specific limitations on this. In this embodiment, it should be noted that in some embodiments, the flexible diffuser film 272 and the flexible display film 271, as well as the flexible diffuser film 272 and the flexible printed circuit board 276, can be laminated together by gluing.

[0091] For further information, please refer to Figure 11-12 and Figure 14 In some optional embodiments of the present application, the display assembly 27 further includes a flexible light-shielding sheet 273, which is sandwiched between the flexible printed circuit board 276 and each flexible display film 271. The flexible light-shielding sheet 273 defines a plurality of light-transmitting holes 2731 located between the flexible printed circuit board 276 and each flexible display film 271. Each light-transmitting region 2711 in each flexible display film 271 is disposed opposite at least one light-transmitting hole 2731, and each light-transmitting hole 2731 contains at least one light-emitting element 275. It should be noted that, in a specific implementation, the number of light-transmitting holes 2731 in corresponding portions of the flexible light-shielding sheet 273 may be the same as or different from the number of light-transmitting regions 2711 on the corresponding flexible display film 271, as long as the requirements of use are met. This embodiment does not impose any specific limitation on this. In addition, the shape and size of the light-transmitting holes 2731 on the corresponding parts of the flexible light-shielding sheet 273 can be the same as or different from the shape and size of the light-transmitting area 2711 on the corresponding flexible display film 271, as long as they can meet the usage requirements. This embodiment does not impose any specific restrictions on this.

[0092] In this embodiment, the provision of the flexible light shielding sheet 273 can reduce the risk of light leakage from the display assembly 27 while ensuring that the display assembly 27 can still be bent, allowing the light emitted by the light-emitting element 275 to be more fully and concentratedly transmitted to the light-transmitting area 2711 of the flexible display film 271, thereby facilitating an improvement in the lighting effect of the display assembly 27. In a specific implementation, the flexible light shielding sheet 273 can be made of a flexible material such as non-transparent silicone, rubber, silicone rubber, sponge, etc., as long as it meets the requirements of use. This embodiment does not impose any specific restrictions on this. In this embodiment, it should be noted that in some embodiments, the flexible light shielding sheet 273 and the flexible display film 271, as well as the flexible light shielding sheet 273 and the flexible printed circuit board 276, can be laminated together by gluing.

[0093] Further, please refer to Figure 11-14 In some optional embodiments of the present application, the surface of each first installation area 2761 is covered with a flexible reflective layer 274 , and each light-emitting element 275 in each first installation area 2761 is exposed from the corresponding flexible reflective layer 274 .

[0094] In this embodiment, the provision of the flexible reflective layer 274 can improve the lighting display effect of the display assembly 27 while ensuring that the display assembly 27 can still be bent. Specifically, in some usage scenarios, after the light emitted by the light-emitting element 275 hits the light-transmitting area 2711 of the flexible display film 271 (or the flexible diffusion film 272), a portion of the light will be reflected. The presence of the flexible reflective layer 274 can, to a certain extent, reflect this portion of the reflected light back to the light-transmitting area 2711 of the flexible display film 271, thereby improving the utilization efficiency of the light and enabling the display assembly 27 to achieve a better lighting display effect. In a specific implementation, the flexible reflective layer 274 can be a flexible reflective film (such as a transparent polyimide film), a paint layer (optionally, to achieve a better reflective effect, a white paint layer can be used as the flexible reflective layer 274), or a reflective ink layer. As long as it meets the usage requirements, this embodiment does not impose any specific restrictions on this. In this embodiment, it should be noted that, in some implementations, the flexible reflective layer 274 and the flexible display film 271 can be laminated together by gluing.

[0095] It should be noted that, in the structural design of the display assembly 27, the flexible diffusion film 272, the flexible light shielding sheet 273, and the flexible light reflecting layer 274 can exist at the same time, or one or two of them can be selected for setting, which depends on the actual use requirements and is not specifically limited in this embodiment. Figure 14As shown, the flexible display film 271, the flexible diffusion film 272, the flexible light shielding sheet 273, the flexible reflective layer 274, and the flexible printed circuit board 276 are stacked in sequence, wherein two adjacent layers can be stacked together by gluing.

[0096] Further, please refer to Figure 11-13 In some optional embodiments of the present application, a flexible printed circuit board 276 is provided with a plurality of light-emitting elements 275 on one side thereof, and further provided with a second mounting area 2762 connected to the first mounting area 2761. The area of ​​the second mounting area 2762 is smaller than that of the first mounting area 2761. The second mounting area 2762 is visibly arranged at the edge of the display component 27 (for example, assuming that the display component 27 is a strip-shaped sheet structure with a certain length and width, the second mounting area 2762 can be located at the length edge or the width edge of the display component 27). In addition, at least one of a current input interface 278 electrically connected to the circuit trace 2763, a current driving element 277, and a plurality of metal test points 279 is provided in the second mounting area 2762. For example, as Figure 11 As shown, a current input interface 278 electrically connected to the circuit trace 2763 , a current driving element 277 , and a plurality of metal test points 279 made of metal material are disposed in the second mounting area 2762 of the flexible printed circuit board 276 .

[0097] In this embodiment, the provision of the current input interface 278 facilitates the electrical connection between the circuit traces 2763 of the flexible printed circuit board 276 and the second control circuit board 25. For example, in a specific application, one end of a flexible flat cable can be connected to the current input interface 278 and the other end of the flexible flat cable can be connected to the current output interface of the second control circuit board 25. This allows for quick and convenient electrical connection between the circuit traces 2763 of the flexible printed circuit board 276 and the second control circuit board 25. The current input interface 278 can be a socket-type connector or other type of communication interface, as long as it meets the requirements of use, and this embodiment does not impose any specific restrictions.

[0098] In this embodiment, the current driving element 277 is provided so that, after the battery 24 is connected via the current input interface 278, the second control circuit board 25 can drive each light-emitting element 275 in the display assembly 27 to emit light in a predetermined manner, thereby displaying the desired information on the flexible display film 271. It should be noted that, in a specific implementation, the current driving element 277 can employ a driver chip commonly used in the art. Since its specific structure and operating principles are well known to those skilled in the art, they will not be described in detail here.

[0099] In this embodiment, the provision of multiple metal test points 279 can facilitate testers to perform corresponding functional tests or fault tests on the display component 27 .

[0100] Further, please refer to Figure 7 as well as Figure 9-10 In some optional embodiments of the present application, the battery 24 module 2 also includes a protective shell 29 made of a light-transmitting material (for example, acrylic, glass, etc.), and the protective shell 29 is installed on the second shell 21 and covers the display component 27.

[0101] In this embodiment, the provision of the light-transmitting protective shell 29 not only ensures that the user can observe the lighting information displayed by the display component 27 through the protective shell 29, but also protects the display component 27 to reduce the risk of damage to the light-emitting element 275 due to impact by foreign objects.

[0102] In addition, it should be noted that other contents of the aerosol generating device disclosed in this application can be found in the prior art and will not be repeated here.

[0103] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application.
