As long as it can meet the use requirements, this embodiment does not impose any specific restrictions on the structural form of the first magnetic member 131, the second magnetic member 141, the third magnetic member 231 and the fourth magnetic member 241.

[0071] Alternatively, in other optional embodiments of the present application, when the third outer wall 211 of the battery module 2 is the second top surface 213 of the battery module 2, the structural form of each connection structure, and the structural form and position distribution of each electrode assembly may be as follows:

[0072] For details, please refer to Figure 16-17 The first connecting structure 13 includes at least one first slide groove 130 extending in a direction perpendicular to the second outer wall 112, and the first slide groove 130 is a T-shaped groove or a dovetail groove. The third connecting structure 23 includes at least one first slide rail 230 that slides with the first slide groove 130. The second connecting structure 14 includes at least one second magnetic member 141. The fourth connecting structure 24 includes at least one fourth magnetic member 241 that is attracted to the second magnetic member 141. The first electrode assembly 12 includes two conductive nails 121 spaced apart on the second outer wall 112. The second electrode assembly 22 includes two conductive elastic pins 221 spaced apart on the fourth outer wall 212. The two conductive nails 121 are in electrical contact with the two conductive elastic pins 221 in a one-to-one correspondence.

[0073] In this embodiment, when the battery module 2 is exhausted or damaged and needs to be replaced, the battery module 2 to be replaced can be pulled out in a direction away from the second outer wall 112 of the atomizer module 1, and then the first slide rail 230 of the new battery module 2 is aligned with the first slide groove 130 of the atomizer module 1 and the battery module 2 is pushed in a direction close to the second outer wall 112 until the fourth outer wall 212 of the battery module 2 abuts against the second outer wall 112 of the atomizer module 1 so that each conductive spring pin 221 forms an electrical contact with each conductive nail 121 and each fourth magnetic member 241 forms a magnetic connection with each second magnetic member 141. In this way, the replacement of the battery module 2 can be completed quickly, and the operation is very convenient. Among them, the battery module 2 can be limited in four directions: up, down, front and back by utilizing the sliding cooperation between the first slide groove 130 and the first slide rail 230, and the battery module 2 can be limited in six directions: up, down, front, back, left and right by utilizing the magnetic connection between the second magnetic part 141 and the fourth magnetic part 241. In this way, a reliable detachable connection can be achieved between the battery module 2 and the atomization module 1, and it is not easy for them to separate from each other.

[0074] Similarly, in some optional embodiments of the present application, when the first outer wall 111 of the atomization module 1 is the first bottom surface 114 of the atomization module 1, the structural form of each connection structure, and the structural form and position distribution of each electrode assembly can also be as follows:

[0075] For details, please refer to Figure 2-3The first connecting structure 13 includes at least one first magnetic member 131, the third connecting structure 23 includes at least one third magnetic member 231 attracted to the first magnetic member 131, the second connecting structure 14 includes at least one second slide groove 140 extending along the height direction of the atomization module 1, the second slide groove 140 is a T-shaped groove or a dovetail groove, and the fourth connecting structure 24 includes at least one second slide rail 240 slidingly engaged with the second slide groove 140; the first electrode assembly 12 includes two conductive nails 121 spaced apart on the first outer wall 111, and the second electrode assembly 22 includes two conductive elastic pins 221 spaced apart on the third outer wall 211, and the two conductive nails 121 are in electrical contact with the two conductive elastic pins 221 in a one-to-one correspondence.

[0076] In this embodiment, when the battery module 2 is exhausted or damaged and needs to be replaced, the battery module 2 to be replaced can be pulled out in a direction away from the first outer wall 111 of the atomizer module 1, and then the second slide rail 240 of the new battery module 2 is aligned with the second slide groove 140 of the atomizer module 1 and the battery module 2 is pushed in a direction close to the first outer wall 111 until the third outer wall 211 of the battery module 2 abuts against the first outer wall 111 of the atomizer module 1 so that each conductive spring pin 221 forms an electrical contact with each conductive nail 121 and each third magnetic member 231 forms a magnetic connection with each first magnetic member 131. In this way, the replacement of the battery module 2 can be completed quickly, and the operation is very convenient. Among them, the battery module 2 can be limited in four directions: front, rear, left and right by utilizing the sliding cooperation between the second slide groove 140 and the second slide rail 240, and the battery module 2 can be limited in six directions: up, down, front, rear, left and right by utilizing the magnetic connection between the first magnetic part 131 and the third magnetic part 231. In this way, a reliable detachable connection can be achieved between the battery module 2 and the atomization module 1, and it is not easy for them to separate from each other.

[0077] Furthermore, in some optional embodiments of the present application, the specific structural forms of the atomization module 1 and the battery module 2 can be as follows:

[0078] Please refer to Figure 6-9 and Figure 16-18The atomization module 1 includes a first shell 11, a mouthpiece 15, an atomizing core 16, a first airflow sensor 17 and a first control circuit board 18 installed in the first shell 11. The first shell 11 has a first outer wall 111 and a second outer wall 112. A first air channel 101 and a storage chamber 102 for storing aerosol-forming substances are provided in the first shell 11. The mouthpiece 15 is connected to the first top surface 113 of the first shell 11 and is communicated with the air outlet end 1012 of the first air channel. The air inlet end 1011 of the first air channel is communicated with the outside world (in a specific implementation, the air inlet end 1011 of the first air channel can be provided on the outer wall of the first shell 11 that is not covered by the second shell 21). When the user bites the mouthpiece 15 to inhale, the outside air can be drawn into the first air channel 101 and form an inhalation airflow on the airflow flow path of the first air channel 101; the atomizing core 1 6 is installed on the air flow path of the first air channel 101 so that the aerosol generated by the atomizer core 16 can be carried away by the suction air flow formed in the first air channel 101 and discharged to the outside for the user to inhale. Moreover, the atomizer core 16 is connected to the storage chamber 102 so that the atomizer core 16 can absorb the aerosol-forming material from the storage chamber 102 for heating and atomization. The first airflow sensor 17 is installed on the air flow path of the first air channel 101 to detect the airflow change in the first air channel 101, and the first airflow sensor 17 is spaced apart from the atomizer core 16. The first control circuit board 18 can be electrically connected to the atomizer core 16, the first airflow sensor 17, and the first electrode assembly 12 respectively by means of wires or the like. The first control circuit board 18 can control the connection and disconnection between the atomizer core 16 and the first electrode assembly 12 according to the detection signal sent by the first airflow sensor 17.

[0079] The battery module 2 includes a second shell 21 and a battery 25 installed in the second shell 21 . The second shell 21 has a third outer wall 211 and a fourth outer wall 212 . The battery 25 is electrically connected to the second electrode assembly 22 .

[0080] In this embodiment, based on the above structural design, the structural principle of the aerosol generating device provided in this embodiment is as follows:

[0081] When the user bites the mouthpiece 15 to inhale, an inhalation airflow is formed on the airflow flow path of the first airway 101, and the inhalation airflow triggers the first airflow sensor 17 to operate, so that the first airflow sensor 17 sends a suction signal to the first control circuit board 18 to indicate that the user is inhaling. When the first control circuit board 18 receives the suction signal, the first control circuit board 18 controls the atomization core 16 to connect to the first electrode assembly 12, so that the battery 25 can provide electrical energy to the atomization core 16 through the second electrode assembly 22 and the first electrode assembly 12. The atomization core 16 is powered on and heated, and atomizes the aerosol-forming substance drawn from the storage chamber 102 into an aerosol that can be inhaled by the user. When the inhalation airflow flows through the atomization core 16, the aerosol is carried away, and 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. When the user stops inhaling, no inhalation airflow is formed in 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 18 to indicate that the user has stopped inhaling. When the first control circuit board 18 receives the stop signal, it disconnects the electrical connection between the atomizer core 16 and the first electrode assembly 12, thereby powering off the atomizer core 16 and stopping atomization. The provision of the first airflow sensor 17 enables the aerosol generating device to operate more intelligently, thereby improving the user experience.

[0082] In this embodiment, it should be noted that the specific structural composition, operating principle, and communication method between the atomizer core 16 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 is not specifically limited in this embodiment. In addition, in a specific implementation, the structural form of the first control circuit board 18 can be a single-chip microcomputer, processor, controller, or other mature device with control functions in the field.

[0083] In this embodiment, it should be noted that in some optional implementations, such as Figure 8 and Figure 18As shown, the battery module 2 may further include a second control circuit board 28 mounted within the second housing 21 and a charging interface 26 exposed on the second bottom surface 214 of the second housing 21. The second control circuit board 28 is electrically connected to the battery 25 and the charging interface 26 respectively through wires or other means. This arrangement allows the user to conveniently charge the battery 25 when the battery 25 is low or depleted, thereby extending the service life of the battery module 2 and enabling the battery module 2 to be used repeatedly. In a specific implementation, the type of the charging interface 26 may be a USB interface or a Type-C interface, which is not specifically limited in this embodiment.

[0084] In some other optional embodiments of the present application, the specific structural forms of the atomization module 1 and the battery module 2 may also be as follows:

[0085] Please refer to Figure 2-4 The atomizer module 1 includes a first shell 11, a nozzle 15, and an atomizer core 16. The first shell 11 has a first outer wall 111 and a second outer wall 112. A first air channel 101 and a storage chamber 102 for storing aerosol-forming substances are provided in the first shell 11. The nozzle 15 is connected to the first top surface 113 and communicates with the air outlet end 1012 of the first air channel. The atomizer core 16 is installed on the airflow path of the first air channel 101 and communicates with the storage chamber 102. The first electrode assembly 12 is electrically connected to the atomizer core 16.

[0086] The battery module 2 includes a second shell 21, a battery 25, a second airflow sensor 27, and a second control circuit board 28 installed in the second shell 21. The second shell 21 has a third outer wall 211 and a fourth outer wall 212. The battery 25 is installed in the second shell 21 and is electrically connected to the second control circuit board 28. The second control circuit board 28 is electrically connected to the second electrode assembly 22. A second air duct 201 is provided in the second shell 21. The second airflow sensor 27 is installed on the airflow flow path of the second air duct 201 and is electrically connected to the second control circuit board 28. The air inlet end 1011 of the first air duct is located on the outer wall where the first shell 11 contacts the second shell 21. The air outlet end 2012 of the second air duct is correspondingly connected to the air inlet end 1011 of the first air duct, and the air inlet end 2011 of the second air duct is connected to the outside world. In the specific implementation, in some optional embodiments, such as Figure 2-3As shown, the air inlet end 1011 of the first air channel can be disposed on the first outer wall 111 of the first housing 11, and correspondingly, the air outlet end 2012 of the second air channel can be disposed on the third outer wall 211 of the second housing 21. In other optional embodiments, the air inlet end 1011 of the first air channel can be disposed on the second outer wall 112 of the first housing 11, and correspondingly, the air outlet end 2012 of the second air channel can be disposed on the fourth outer wall 212 of the second housing 21. The air inlet end 2011 of the second air channel can be disposed on an outer wall of the second housing 21 that is not covered by the first housing 11 (such as the second bottom surface 214 of the second housing 21).

[0087] In this embodiment, based on the above structural design, the structural principle of the aerosol generating device provided in this embodiment is as follows:

[0088] When the user bites the mouthpiece 15 to inhale, an inhalation airflow is formed on the airflow flow path connecting the first airway 101 and the second airway 201. The inhalation airflow triggers the second airflow sensor 27 to operate, so that the second airflow sensor 27 sends a suction signal to the second control circuit board 28 to indicate that the user is inhaling. When the second control circuit board 28 receives the suction signal, the second control circuit board 28 controls the second electrode assembly 22 to connect to the battery 25, so that the atomizer core 16 can be connected to the battery 25 through the first electrode assembly 12 and the second electrode assembly 22, thereby energizing and heating the aerosol-forming substance drawn from the storage chamber 102 and atomizing the aerosol-forming substance into an aerosol that can be inhaled by the user. When the inhalation airflow flows through the atomizer core 16, the aerosol is carried away, and 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. When the user stops inhaling, no inhalation airflow is formed in the airflow path connecting the first airway 101 and the second airway 201, causing the second airflow sensor 27 to send a stop signal to the second control circuit board 28 to indicate that the user has stopped inhaling. When the second control circuit board 28 receives the stop signal, it disconnects the electrical connection between the second electrode assembly 22 and the battery 25, thereby disconnecting the atomizer core 16 from the power supply and stopping atomization. The provision of the second airflow sensor 27 enables the aerosol generating device to operate more intelligently, thereby improving the user experience.

[0089] In this embodiment, it should be noted that, similarly, in some optional implementations, such as Figure 4As shown, the battery module 2 may further include a charging port 26 exposed on the second bottom surface 214 of the second housing 21. The charging port 26 is electrically connected to the second control circuit board 28. This configuration allows the user to conveniently charge the battery 25 when the battery 25 is low or depleted, thereby extending the service life of the battery module 2 and enabling repeated use of the battery module 2. 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.

[0090] In this embodiment, it can be understood that the aerosol generating device provided in this embodiment (such as Figure 1-4 ) and Figure 5-8 / The main difference of the aerosol generating device provided by the embodiments shown in / 15-18 is that the setting position of the airflow sensor and the number of control circuit boards have changed, that is, the setting position of the airflow sensor is transferred from the first shell 11 of the atomization module 1 to the second shell 21 of the battery module 2, and the control circuit board set in the first shell 11 is omitted. The benefit 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 module 2 is usually higher than the service life of the atomization module 1.

[0091] Further, please refer to Figure 4 、 Figure 8-9 and Figure 18 In some optional embodiments of the present application, the battery module 2 also includes a display component 29 for displaying visual information and electrically connected to the second control circuit board 28. The display component 29 is installed on any outer wall of the second shell 21 except the third outer wall 211 and the fourth outer wall 212. That is, the display component 29 is installed on the outer wall of the second shell 21 that is not covered by the first shell 11, such as the front outer wall, rear outer wall, right outer wall and other outer surfaces of the second shell 21 that are convenient for users to observe.

[0092] In this embodiment, by adding a display component 29 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 29 can display visual information such as the remaining power of the battery 25, the operating temperature of the battery 25, the output power of the battery 25, the remaining amount of aerosol-forming material in the storage cavity 102, and preset animation patterns, which is conducive to improving the user experience.

[0093] In this embodiment, it should be noted that, in specific implementation, the structural form of the display component 29 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.; it can also be an inflexible 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.

[0094] Furthermore, in some optional embodiments of the present application, the specific arrangement and structural form of the display assembly 29 may be as follows:

[0095] like Figure 8-12 As shown, the display assembly 29 includes a flexible printed circuit board 296 having a circuit track 2963 and a display film 291 made of a flexible material. A plurality of light-emitting elements 295 electrically connected to the circuit track 2963 are fixed to the surface of the flexible printed circuit board 296 along one side of its thickness direction. The surface of the flexible printed circuit board 296 facing away from the plurality of light-emitting elements 295 can be connected to the second shell 21 by gluing (the glue can be double-sided tape) and covers the second shell 21 except the third outer wall 211 and the fourth outer wall 212. At least one outer wall of the display film 296, the circuit track 2963 is electrically connected to the second control circuit board 28, and the display film 291 can be fixedly connected to the flexible printed circuit board 296 by gluing (the glue can be double-sided tape, structural glue, optically transparent glue, etc.) on one side of the flexible printed circuit board 296 where multiple light-emitting elements 295 are provided and covers each light-emitting element 295. The display film 291 has multiple light-transmitting areas 2911 for light emitted by the light-emitting elements 295 to pass through. The area of ​​the display film 291 other than the light-transmitting area 2911 is a shading area 2912.

[0096] In this embodiment, it is understood that the flexible printed circuit board 296, also known as an FPC (Flexible Printed Circuit) board, is a flexible circuit board with printed circuit traces 2963. It has advantages such as good flexibility, light weight, and thinness. In a specific manufacturing process, the desired flexible printed circuit board 296 can be obtained by printing the circuit traces 2963 on a polyimide film or a polyester film. It is also understood that the flexible printed circuit board 296 can serve as a mounting carrier for the multiple light-emitting elements 295, and the circuit traces 2963 on the flexible printed circuit board 296 can serve as a medium for electrically connecting the multiple light-emitting elements 295 to the second control circuit board 28.

[0097] In this embodiment, it should be noted that, in a specific implementation, the light-emitting element 295 may be a component that emits light when energized, such as an LED lamp bead. Furthermore, the light-emitting element 295 may be secured to the surface of the flexible printed circuit board 296 by welding or bonding (e.g., with insulating glue or conductive glue) and electrically connected to the circuit traces 2963 of the flexible printed circuit board 296.

[0098] In this embodiment, it should also be noted that, in specific implementation, the material of the display film 291 can be flexible materials such as 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), etc. As long as it can meet the use requirements, this embodiment does not impose any specific restrictions on the specific material of the display film 291. Among them, in some optional embodiments, when the display film 291 is made of a transparent flexible material, a light-transmitting area 2911 and a light-shielding area 2912 can be formed on the display film 291 by applying light-shielding ink, etc. For example, when the display film 291 is a transparent polyimide film, light-shielding ink can be applied on 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 2912 of the display film 291, and the area of ​​the polyimide film not coated with the light-shielding ink can be regarded as the light-transmitting area 2911 of the display film 291. In other optional embodiments, when the display film 291 is made of an opaque flexible material, a light-transmitting area 2911 and a light-blocking area 2912 can be formed on the display film 291 by laser engraving or the like. For example, when the display film 291 is an opaque PET film, the required light-transmitting area 2911 (the light-transmitting area 2911 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 2912. Of course, the display film 291 can also be other film structures having light-transmitting areas 2911 and light-blocking areas 2912 that are already mature in the art. For example, in other optional embodiments, the display film 291 can also be a PET color film having light-transmitting areas 2911 and light-blocking areas 2912 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 2911 on the display film 291 and the shape and size of each light-transmitting area 2911 can be determined according to actual use requirements, and this embodiment does not impose specific restrictions on this. Optionally, the shape of the light-transmitting area 2911 can be a text shape, a graphic shape (such as a dot shape, a line shape, etc.), a number shape, a letter shape, etc. When the light emitted by the light-emitting element 295 reaches the corresponding light-transmitting area 2911, the light display information of the corresponding shape can be displayed. For example, when the light-emitting element 295 emits When the emitted light reaches the letter-shaped light-transmitting area 2911, the user can observe the illuminated letters on the surface of the display film 291. Thus, by combining multiple light-transmitting areas 2911 of different shapes, a variety of light display information can be obtained. Combining light display information of different shapes can thus represent various information about the aerosol generating device, such as the remaining charge of the battery 25, the operating temperature of the battery 25, the output power of the battery 25, the remaining amount of aerosol-forming material in the storage chamber 102, preset animated patterns, etc. Furthermore, the number of light-emitting elements 295 corresponding to each light-transmitting area 2911 can be one or more, depending on actual usage requirements and is not specifically limited in this embodiment.

[0099] In this embodiment, based on the above-mentioned structural design, the second control circuit board 28 can control the multiple light-emitting elements 295 to be powered on and emit light or powered off and stop emitting light. The light emitted by the multiple light-emitting elements 295 when powered on and emit light can be displayed in the light-transmitting area 2911 of the display film 291, that is, the light-transmitting area 2911 of the display film 291 can be used as the light display area of ​​the display component 29, thereby realizing the display function of the display component 29. In addition, since the display film 291 and the flexible printed circuit board 296 are both flexible structures, the display assembly 29 formed by stacking the display film 291 and the flexible printed circuit board 296 is also a flexible structure, so that the display assembly 29 has a bendable property, so that the display assembly 29 can easily cover at least one outer wall of the second shell 21 that is not covered by the first shell 11. For example, the display assembly 29 can cover at least two outer walls of the second shell 21 that are not covered by the first shell 11 along the circumference of the second shell 21. This is conducive to improving the information display range of the aerosol generating device, so that the aerosol generating device can display more visual information to the user in multiple directions. Moreover, compared with flexible OLED touch screens, flexible AMOLED touch screens or LED flat screens, the display assembly 29 provided in this embodiment has the advantages of simple structure and low cost.

[0100] Further, please refer to Figure 8-9In some optional embodiments of the present application, the battery module 2 also includes a protective shell 210 made of a light-transmitting material (for example, acrylic, glass, etc.), and the protective shell 210 is installed on the second shell 21 and covers the display component 29.

[0101] In this embodiment, the provision of the light-transmissive protective shell 210 not only ensures that the user can observe the light information displayed by the display assembly 29 through the protective shell 210, but also protects the display assembly 29 to reduce the risk of damage to the light-emitting element 295 due to impact by foreign objects. It should be noted that, in specific implementations, in some optional embodiments, a gap may exist between the inner surface of the protective shell 210 and the display film 291, and the size of the gap may be 0.1 mm to 2 mm. The provision of this gap can, on the one hand, serve as a heat dissipation space for the display assembly 29 to improve the heat dissipation efficiency of the display assembly 29 during operation, and on the other hand, it can prevent the inner surface of the protective shell 210 from squeezing the display assembly 29 and damaging the light-emitting element 295 in the display assembly 29.

[0102] Further, please refer to Figure 10-13 In some optional embodiments of the present application, a flexible printed circuit board 296 is provided with a plurality of light-emitting elements 295 on one side thereof, and has a first mounting area 2961 and a second mounting area 2962 connected to each other, the area of ​​the first mounting area 2961 is larger than the area of ​​the second mounting area 2962, and the second mounting area 2962 is visibly arranged at the edge position of the display component 29 (for example, assuming that the display component 29 is a strip sheet with a certain length and width, the second mounting area 2962 is located at the length edge or the width edge of the display component 29), the plurality of light-emitting elements 295 are fixed in the first mounting area 2961, and the second mounting area 2962 is provided with at least one of a current input interface 298 electrically connected to the circuit trace 2963, a current driving element 297, and a plurality of metal test points 299.

[0103] In this embodiment, the provision of the current input interface 298 facilitates the electrical connection between the circuit trace 2963 of the flexible printed circuit board 296 and the first control circuit board 18. For example, in some specific application scenarios, simply plugging one end of a flexible flat cable into the current input interface 298 and the other end of the flexible flat cable into the current output interface (not shown) of the second control circuit board 28 can quickly establish an electrical connection between the circuit trace 2963 of the flexible printed circuit board 296 and the second control circuit board 28, making operation very convenient. The current input interface 298 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 specific limitations on this. Accordingly, the structure of the current output interface of the second control circuit board 28 can be the same as the structure of the current input interface 298 of the flexible printed circuit board 296.

[0104] In this embodiment, the provision of the current driving element 297 enables, after the battery 25 is connected via the current input interface 298, the second control circuit board 28 to control the individual light-emitting elements 295 in the display assembly 29 to emit light in a predetermined manner, thereby displaying the desired information on the display film 291. It should be noted that, in a specific implementation, the current driving element 297 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.

[0105] In this embodiment, the provision of multiple metal test points 299 can facilitate testers to perform corresponding functional tests or fault tests on the display component 29 .

[0106] Furthermore, considering that in some specific application scenarios, when a single display film 291 with a longer length is used to simultaneously cover the light-emitting elements 295 in each first installation area 2961, it is easy for some light-emitting elements 295 to be damaged during the process of installing the display component 29 on the outer walls of the second shell 21 in multiple different directions along its own circumference. The reason is that in the process of winding the display component 29 around the outer walls of the second shell 21 in multiple different directions along the circumference of the second shell 21, it is difficult to avoid bending the display component 29 multiple times. If the display component 29 needs to be reinstalled due to improper installation, the display component 29 needs to be bent more times. Bending, and each time the display component 29 is bent, the entire display film 291 will be stretched to varying degrees and local stress concentration will occur. The greater the degree of bending of the display component 29, the greater the degree of stretching of the display film 291 and the more obvious the local stress concentration will be. Each time the display film 291 is stretched, the light-emitting element 295 will be squeezed to varying degrees, and the portion of the display film 291 where the local stress concentration occurs will squeeze the light-emitting element 295 the most. Therefore, when the display component 29 is repeatedly bent, especially when the degree of bending is large, it will easily cause some of the light-emitting elements 295 to be crushed by the display film 291.

[0107] Based on the above findings, in order to solve the technical problem that when a single long display film 291 is used to simultaneously cover the light-emitting elements 295 in each first mounting area 2961, some of the light-emitting elements 295 are easily damaged during the process of installing the display assembly 29 on multiple outer walls of the second housing 21 in different directions, multiple pieces of shorter flexible display films 2910 can be used to replace the single long display film 291. Specifically, please refer to Figure 8-9 as well as Figure 13-14 In some optional embodiments of the present application, at least two first mounting areas 2961 are provided on one side surface of the flexible printed circuit board 296 along its own thickness direction, and the at least two first mounting areas 2961 are spaced apart along the length direction of the flexible printed circuit board 296, and multiple light-emitting elements 295 are fixed in each first mounting area 2961; the display film 291 includes at least two flexible display films 2910 spaced apart, each flexible display film 2910 covers a first mounting area 2961, and each flexible display film 2910 has multiple light-transmitting areas 2911, and among the multiple outer walls of the second shell 21 in different directions covered by the flexible printed circuit board 296, each outer wall corresponds to at least one flexible display film 2910.

[0108] In the technical solution of this embodiment, since each first mounting area 2961 is individually covered by a relatively short flexible display film 2910, and each flexible display film 2910 is separately provided rather than being connected to form a single-piece film structure, the bending and stretching of each flexible display film 2910 are independent of each other and do not affect each other. For example, please refer to Figure 9 as well as Figure 13-14 After the first flexible display film 2910 is covered on the first outer wall of the second shell 21 (such as the front outer wall of the second shell 21), in the process of covering the second flexible display film 2910 on the second outer wall of the second shell 21 (such as the right outer wall of the second shell 21) by bending the display component 29 once, the first flexible display film 2910 will not be stretched due to the bending of the display component 29 this time, so that the first flexible display film 2910 will not squeeze the light-emitting element 295 opposite to it during this process, thereby effectively reducing the risk of some light-emitting elements 295 being crushed by the flexible display film 2910 when the display component 29 is installed on multiple outer walls of the second shell 21 in different directions along the circumference of the second shell 21.

[0109] In this embodiment, it should be noted that, in some specific application scenarios, in order to improve the production efficiency of the display component 29, multiple pieces of shorter flexible display films 2910 can be obtained by cutting a single piece of longer display film 291. For example, a single piece of longer display film 291 can be used to simultaneously cover the light-emitting elements 295 in each first installation area 2961, and before the display component 29 is installed on multiple outer walls of the second shell 21 in different directions, the portion of the single piece of longer display film 291 that does not cover the first installation area 2961 can be cut, so that multiple pieces of shorter flexible display films 2910 with intervals can be obtained in the length direction of the display component 29.

[0110] Further, please refer to Figure 13-14 In some optional embodiments of the present application, the display component 29 further includes a flexible diffusion membrane 292 sandwiched between the flexible printed circuit board 296 and the display film 291 , and the flexible diffusion membrane 292 covers each light-transmitting area 2911 of the display film 291 .

[0111] In this embodiment, the provision of the flexible diffuser film 292 ensures that the display assembly 29 is bendable while uniformly diffusing the light emitted by the light-emitting element 295. This allows the light emitted by the light-emitting element 295 to be more evenly diffused onto the light-transmitting area 2911 of the display film 291, thereby improving the uniformity of the light display of the display assembly 29. In a specific implementation, the flexible diffuser film 292 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 films with light diffusing properties, as long as they meet the requirements of use. This embodiment does not impose specific limitations on this. Alternatively, in some embodiments, the flexible diffuser film 292 can be a yellow fluorescent ink film. In this embodiment, it should be noted that, in a specific implementation, the flexible diffuser film 292 and the display film 291, as well as the flexible diffuser film 292 and the flexible printed circuit board 296, can be laminated together using glue.

[0112] For further information, please refer to Figure 13-14 In some optional embodiments of the present application, the display assembly 29 further includes a flexible light-shielding sheet 293 sandwiched between the flexible printed circuit board 296 and the display film 291. The flexible light-shielding sheet 293 is provided with a plurality of light-transmitting holes 2931. Each light-transmitting hole 2931 is provided with at least one light-emitting element 295. Each light-transmitting area 2911 is provided opposite to at least one light-transmitting hole 2931. It should be noted that, in a specific implementation, the number of light-transmitting holes 2931 on the flexible light-shielding sheet 293 and the number of light-transmitting areas 2911 on the display film 291 can be the same or different, as long as the requirements of use are met, and this embodiment does not impose any specific restrictions on this. In addition, the shape and size of the light-transmitting holes 2931 on the flexible light-shielding sheet 293 and the corresponding light-transmitting areas 2911 on the display film 291 can be the same or different, as long as the requirements of use are met, and this embodiment does not impose any specific restrictions on this.

[0113] In this embodiment, the provision of the flexible light shielding sheet 293 can reduce the risk of light leakage from the display assembly 29 while ensuring that the display assembly 29 can still be bent, allowing the light emitted by the light-emitting element 295 to be more fully and concentratedly transmitted to the light-transmitting area 2911 of the display film 291, thereby facilitating an improvement in the lighting effect of the display assembly 29. In a specific implementation, the flexible light shielding sheet 293 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 specific limitations on this. In this embodiment, it should be noted that in some embodiments, the flexible light shielding sheet 293 and the display film 291, as well as the flexible light shielding sheet 293 and the flexible printed circuit board 296, can be laminated together by gluing.

[0114] For further information, please refer to Figure 13-14 In some optional embodiments of the present application, the display component 29 further includes a flexible reflective layer 294 sandwiched between the display film 291 and the flexible printed circuit board 296 , and each light-emitting element 295 is exposed from the flexible reflective layer 294 .

[0115] In this embodiment, the provision of the flexible reflective layer 294 can improve the lighting display effect of the display assembly 29 while ensuring that the display assembly 29 can still be bent. Specifically, in some usage scenarios, after the light emitted by the light-emitting element 295 hits the light-transmitting area 2911 of the display film 291 (or the flexible diffuser 292), a portion of the light will be reflected. The presence of the flexible reflective layer 294 can, to a certain extent, reflect this partially reflected light back to the light-transmitting area 2911 of the display film 291, thereby improving the utilization efficiency of the light and enabling the display assembly 29 to achieve a better lighting display effect. In a specific implementation, the flexible reflective layer 294 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 294), 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 294 and the display film 291 can be laminated together by gluing.

[0116] It should be noted that, in the structural design of the display assembly 29 including the display film 291, the flexible diffusion film 292, the flexible light shielding film 293, and the flexible reflective layer 294 can exist at the same time, or one or two of them can be selected for configuration, which is determined according to actual use requirements and is not specifically limited in this embodiment. Figure 13-14As shown, the display film 291, the flexible diffusion film 292, the flexible light shielding sheet 293, the flexible reflective layer 294, and the flexible printed circuit board 296 are stacked in sequence, wherein two adjacent layers can be stacked together by gluing.
