Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to a flexible display component and an aerosol generating device. Background Art

[0002] An aerosol generating device is an electronic device that can use electric heating to atomize aerosol-forming substances such as tobacco oil and liquid medicine stored in it into aerosols. Currently, aerosol generating devices on the market usually include structures such as an atomizer core, a battery, and a storage bin. Among them, the storage bin generally stores aerosol-forming substances, and the aerosol-forming substances in the storage bin can be transferred to the atomizer core through capillary action and other methods. When the user uses the aerosol generating device for inhalation, the battery provides electrical energy to the atomizer core, so that the atomizer core can be powered on and heated. The heat generated by the power supply and heating of the aerosol core can be used to atomize the aerosol-forming substances transferred to the atomizer core into an aerosol that can be inhaled by the user.

[0003] As an aerosol generating device is used continuously, the battery power and the amount of aerosol-forming substance in the aerosol generating device gradually decrease. To facilitate users to readily and intuitively know the remaining battery power and the remaining amount of aerosol-forming substance in the aerosol generating device, the aerosol generating device is usually equipped with a display screen on the outside that can display information such as the remaining battery power and the remaining amount of aerosol-forming substance. However, current aerosol generating devices with display screens generally have the following problems:

[0004] Since the display screen used is usually a display screen with a rigid glass substrate, the display screen can usually only be installed on one of the outer surfaces of the aerosol generating device (such as the front, back, left side, right side or top surface of the aerosol generating device), which leads to the problem of a small information display range of the aerosol generating device. With the continuous development of electronic atomization technology, more and more information needs to be displayed on the display screen. Therefore, how to improve the information display range of the aerosol generating device so that the aerosol generating device can display more information to the user is a technical problem that needs to be urgently solved by technical personnel in this field.

[0050] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, when an element is described as being “fixed to” another element, it may be directly on the other element or one or more intervening elements may be present therebetween. When an element is described as being “connected to” another element, it may be directly connected to the other element or one or more intervening elements may be present therebetween.

[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0054] Please refer to Figure 1-10 and Figure 14-17 One embodiment of the present application provides a flexible display assembly 1 that can be used to display visual information about an aerosol generating device, such as the remaining battery level, operating power, remaining amount of aerosol-forming material, a preset pattern, and other visual information. The flexible display assembly 1 is sheet-shaped when in a non-enclosed, unfolded state. The flexible display assembly 1 has a first end 1A and a second end 1B that are opposite to each other along its length. At least one of the first end 1A and the second end 1B is provided with a connecting structure 10. When the flexible display assembly 1 is enclosed and the first end 1A is connected to the second end 1B via the connecting structure 10, the flexible display assembly 1 assumes a cylindrical shape, and a light-emitting surface 1C of the flexible display assembly 1 is located on the outer periphery of the cylindrical flexible display assembly 1. It can be understood here that when the flexible display component 1 is cylindrical, the flexible display component 1 can specifically be a cylindrical structure with a regular or irregular shape such as a rectangular, circular, elliptical, waist-shaped, or water-drop-shaped cross-section, which can be determined according to the actual application scenario (generally speaking, the shape formed by the flexible display component 1 after being enclosed is adapted to the shape of the shell 2 of the aerosol generating device. For example, if the shell 2 of the aerosol generating device is cylindrical, the shape formed by the flexible display component 1 after being enclosed can be a cylindrical structure with a circular cross-section). This embodiment does not make specific limitations on this.

[0055] In this embodiment, it should be noted that, in some optional implementations, the flexible display assembly 1 may be structured in the form of a flexible OLED (organic light-emitting diode) touch screen, a flexible AMOLED (active-matrix organic light-emitting diode) touch screen, or other types of flexible touch screens. Furthermore, the connection structure 10 may be structured in any manner that can connect the two ends of the flexible display assembly 1 along its length, such as an adhesive structure (such as double-sided tape, Velcro, etc.), a magnetic structure, a plug-in connector, etc., as long as it can meet the requirements of use, and this embodiment does not impose any specific restrictions on this.

[0056] In the technical solution of this embodiment, since the flexible display component 1 has a bendable property and can be enclosed into a cylindrical structure, when the flexible display component provided by this application is applied to an aerosol generating device, it is only necessary to install the sheet-shaped flexible display component 1 along the circumference of the shell 2 of the aerosol generating device, so that the flexible display component 1 is arranged 360 degrees around the shell 2 along the circumference of the shell 2. In this way, the light-emitting surface 1C of the flexible display component 1 can be distributed on multiple outer surfaces of the shell 2 in different directions along the circumference of the shell 2, thereby improving the information display range of the aerosol generating device, so that the aerosol generating device can display information to the user in a 360-degree full-scale manner, that is, the user can observe the visual information of the aerosol generating device from four different directions: the front, back, left, and right sides of the aerosol generating device.

[0057] In addition, since the flexible display component 1 has two opposite ends along its length, at least one of the two ends is provided with a connecting structure 10, and when one end is connected to the other end through the connecting structure 10, the flexible display component 1 can be enclosed into a cylindrical structure. Therefore, when the flexible display component provided in this embodiment is applied to an aerosol generating device, on the one hand, the flexible display component 1 can be enclosed into a cylindrical structure first, and then the cylindrical flexible display component 1 can be mounted on the shell 2 of the aerosol generating device, thereby realizing the installation and use of the flexible display component 1; on the other hand, the flexible display component 1 can be first wrapped around the shell 2 along the circumference of the shell 2 of the aerosol generating device, and then the two ends of the flexible display component 1 can be connected through the connecting structure 10, thereby realizing the installation and use of the flexible display component 1. In this way, the installation flexibility and convenience of the flexible display component 1 are improved.

[0058] Furthermore, in some optional embodiments of the present application, the flexible display assembly 1 may be a flexible touch screen such as a flexible OLED touch screen or a flexible AMOLED touch screen. In addition, the flexible display assembly 1 may also be a flexible touch screen such as a flexible OLED touch screen or a flexible AMOLED touch screen.

[0059] For details, please refer to Figure 2-10 The flexible display assembly 1 includes a flexible display film 11 and a flexible printed circuit board 16 having a circuit track 160. A plurality of light-emitting elements 14 electrically connected to the circuit track 160 are fixed on a surface of one side of the flexible printed circuit board 16 along its thickness direction. The plurality of light-emitting elements 14 are spaced apart at least along the length direction of the flexible printed circuit board 16. The flexible display film 11 can be fixedly laminated on a surface of one side of the flexible printed circuit board 16 by gluing or other means and covers the plurality of light-emitting elements 14. The flexible display film 11 has a plurality of light-transmitting areas 111 for transmitting light emitted by the light-emitting elements 14. The area of ​​the flexible display film 11 other than the light-transmitting areas 111 is a light-shielding area 112. Among them, the connecting structure 10 is arranged at at least one end of the flexible printed circuit board 16 along its own length direction and / or at at least one end of the flexible display film 11 along its own length direction, that is, along the length direction of the flexible display component 1, the connecting structure 10 can be arranged only on the end of the flexible display film 11, or only on the end of the flexible printed circuit board 16, or at the end of the flexible display film 11 and the end of the flexible printed circuit board 16. The setting position of the connecting structure 10 can be determined according to the structural form of the connecting structure 10, as long as it can achieve the connection of the two ends of the flexible display component 1 along its own length direction. This embodiment does not impose any specific restrictions on this.

[0060] In this embodiment, it can be understood that the flexible printed circuit board 16, also known as an FPC (Flexible Printed Circuit, FPC) board, is a flexible circuit board printed with circuit tracks 160. It has the advantages of good flexibility, light weight, and thin thickness. In the specific manufacturing process, the required flexible printed circuit board 16 can be obtained by printing the circuit tracks 160 on a polyimide film or a polyester film.

[0061] In this embodiment, it should be noted that, in a specific implementation, the light-emitting element 14 may be a component that emits light when energized, such as an LED lamp bead. Furthermore, the light-emitting element 14 may be secured to the surface of the flexible printed circuit board 16 by welding or bonding (e.g., with insulating or conductive glue) and electrically connected to the circuit traces 160 of the flexible printed circuit board 16.

[0062] In this embodiment, it should also be noted that, in specific implementation, the material of the flexible display film 11 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 11. Among them, in some optional embodiments, when the flexible display film 11 is made of a transparent flexible material, a light-transmitting area 111 and a light-shielding area 112 can be formed on the flexible display film 11 by applying light-shielding ink, etc. For example, when the flexible display film 11 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 112 of the flexible display film 11, and the area of ​​the polyimide film not coated with the light-shielding ink can be regarded as the light-transmitting area 111 of the flexible display film 11. In other optional embodiments, when the flexible display film 11 is made of an opaque flexible material, a light-transmitting area 111 and a light-shielding area 112 can be formed on the flexible display film 11 by laser engraving or the like. For example, when the flexible display film 11 is an opaque PET film, the required light-transmitting area 111 can be engraved on the surface of the PET film by laser engraving (the light-transmitting area 111 is essentially a through hole in this case), and the unengraved area in the PET film is formed as the light-shielding area 112. Of course, the flexible display film 11 can also be other film structures having light-transmitting areas 111 and light-shielding areas 112 that are already mature in the art. For example, in other optional embodiments, the flexible display film 11 can also be a PET color film having light-transmitting areas 111 and light-shielding areas 112 that are already mature in the art. As long as it can meet the use requirements, this embodiment does not impose specific restrictions on this.In addition, in a specific implementation, the number of light-transmitting areas 111 on the flexible display film 11 and the shape and size of each light-transmitting area 111 can be determined according to actual usage requirements, and this embodiment does not impose any specific restrictions on this. Optionally, the shape of the light-transmitting area 111 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 14 reaches the corresponding light-transmitting area 111, light display information of the corresponding shape can be displayed. For example, when the light emitted by the light-emitting element 14 reaches the light-transmitting area 111 in the shape of a letter, the user can observe the glowing letters on the surface of the flexible display film 11. In this way, by combining multiple light-transmitting areas 111 of different shapes, light display information of multiple different shapes can be obtained, and thus by combining light display information of different shapes, various visual information of the aerosol generating device can be represented, such as the remaining power of the aerosol generating device, the working power, the remaining amount of the aerosol-forming substance, the preset pattern and other visual information. In addition, the number of light-emitting elements 14 corresponding to each light-transmitting area 111 can be one or more, which can be determined according to actual use requirements and is not specifically limited in this embodiment.

[0063] In this embodiment, based on the above-described structural design, the light emitted by the multiple light-emitting elements 14 when energized can be displayed in the light-transmitting regions 111 of the flexible display film 11. That is, the multiple light-transmitting regions 111 of the flexible display film 11 can serve as the light-emitting surface 1C of the flexible display assembly 1, thereby realizing the display function of the flexible display assembly 1. In addition, because the flexible display film 11 and the flexible printed circuit board 16 are both flexible structures, the display assembly formed by laminating the flexible display film 11 and the flexible printed circuit board 16 is also a flexible structure, thereby making the flexible display assembly 1 bendable. Moreover, compared to flexible touch screens such as flexible OLED touch screens and flexible AMOLED touch screens, the flexible display assembly 1 provided in this embodiment has the advantages of simple structure and low cost.

[0064] Optionally, in some optional embodiments of the present application, the arrangement position and structural form of the connection structure 10 may be as follows:

[0065] For details, please refer to Figure 2 and Figure 4The flexible printed circuit board 16 has a first end 1A and a second end 1B opposite to each other along its length direction. Along the thickness direction of the flexible printed circuit board 16, the first end 1A has a first area 1A1 not covered by the flexible display film 11 on the side close to the flexible display film 11, and the second end 1B has a second area 1B2 on the side facing away from the flexible display film 11. At least one of the first area 1A1 and the second area 1B2 is covered with a connecting structure 10 including a glue layer 101 (the glue layer 101 can specifically be a type of glue such as double-sided tape). Exemplarily, the structure is that the glue layer 101 is arranged on the second area 1B2 of the second end 1B. Such a configuration allows the first end 1A and the second end 1B to be quickly bonded together through the glue layer 101, so that when the flexible display component 1 provided in this embodiment is applied to an aerosol generating device, it is convenient to quickly install the flexible display component 1 on the shell 2 of the aerosol generating device. For example, during installation and use, it is only necessary to wrap the flexible display component 1 around the shell 2 of the aerosol generating device along the circumference of the shell 2 of the aerosol generating device, so that the flexible display film 11 is set back to the shell 2, and then the first area 1A1 of the first end 1A and the second area 1B2 of the second end 1B are bonded together through the glue layer 101. In this way, the flexible component can be quickly installed, and the operation is very convenient.

[0066] Alternatively, in some other optional embodiments of the present application, the arrangement position and structural form of the connecting structure 10 may also be as follows:

[0067] For details, please refer to Figure 2 as well as Figure 5-6 The flexible printed circuit board 16 has a first end 1A and a second end 1B along its length. Along the thickness direction of the flexible printed circuit board 16, the first end 1A has a first area 1A1 not covered by the flexible display film 11 on the side close to the flexible display film 11, and the second end 1B has a second area 1B2 on the side facing away from the flexible display film 11. A connecting structure 10 is provided in both the first area 1A1 and the second area 1B2. The connecting structure 10 is one of a Velcro, a magnetic structure, and a plug-in connector.

[0068] In this embodiment, it can be understood that if Figure 5 As shown, when the structural form of the connecting structure 10 is Velcro, the connecting structure 10 includes a hook surface 104 and a hairy surface 105. For example, the hook surface 104 is arranged on the first area 1A1, and the hairy surface 105 is arranged on the second area 1B2.

For example, the first magnetic member 102 is arranged on the first area 1A1, and the second magnetic member 103 is arranged on the second area 1B2. In this way, the first end 1A and the second end 1B can be quickly attracted together by simply moving the first magnetic member 102 close to the second magnetic member 103.

[0070] In this embodiment, it can also be understood that, if Figure 6 As shown, when the structural form of the connection structure 10 is a plug-in connector, the connection structure 10 includes a plug 106 with a protrusion and a socket 107 with a groove.

At least one of the first area 1A1 and the second area 1B2 is covered with a connecting structure 10 including a glue layer 101 (the glue layer 101 can be a double-sided tape or other type of glue). In an exemplary embodiment, the glue layer 101 is disposed on the second area 1A1 of the first end 1A of the flexible printed circuit board 16. This arrangement allows the first end 1A and the second end 1B to be quickly bonded together via the glue layer 101.

[0073] Optionally, in some further optional embodiments of the present application, the arrangement position and structural form of the connection structure 10 may also be as follows:

[0074] For details, please refer to 2 and Figure 8-9 One end of the flexible printed circuit board 16 along its own length direction is a first end 1A, and one end of the flexible display film 11 along its own length direction is a second end 1B. Along the thickness direction of the flexible display component 1, the first end 1A has a first area 1A1 not covered by the flexible display film 11 on the side close to the flexible display film 11, and the second end 1B has a second area 1B2 not covered by the flexible printed circuit board 16 on the side close to the flexible printed circuit board 16.

[0075] In this embodiment, it should be noted that when the structure of the connecting structure 10 is a Velcro, the first end 1A and the second end 1B can be quickly connected together by pasting. The structure and arrangement of the Velcro are similar to those of the embodiment. Figure 5 When the connection structure 10 is a magnetic structure, the first end 1A and the second end 1B can be quickly connected together by magnetic attraction. The structure and arrangement of the magnetic structure are similar to those shown in FIG. Figure 5 When the structure of the connection structure 10 is a plug-in connector, the first end 1A and the second end 1B can be quickly connected together by snapping together. The structure and arrangement of the plug-in connector are similar to those of the embodiment shown in FIG. Figure 6 The embodiments shown are similar and will not be described again here.

[0076] For further information, please refer to Figure 11-13 In some optional embodiments of the present application, the flexible display assembly 1 further includes a flexible diffusion film 12 , which is sandwiched between the flexible display film 11 and the flexible printed circuit board 16 , and the flexible diffusion film 12 covers each light-transmitting area 111 .

[0077] In this embodiment, the provision of the flexible diffusion film 12 can ensure that the flexible display assembly 1 can be bent, while uniformly diffusing the light emitted by the light-emitting element 14. This allows the light emitted by the light-emitting element 14 to be more evenly diffused onto the light-transmitting area 111 of the flexible display film 11, thereby improving the uniformity of the light display of the flexible display assembly 1. In a specific implementation, the flexible diffusion film 12 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 diffusion functions. This embodiment does not impose specific limitations on this as long as it meets the requirements of use. Alternatively, in some embodiments, the flexible diffusion film 12 can be a yellow fluorescent ink film. In this embodiment, it should be noted that, in a specific implementation, the flexible diffusion film 12 and the flexible display film 11, as well as the flexible diffusion film 12 and the flexible printed circuit board 16, can be laminated together by gluing.

[0078] For further information, please refer to Figure 13 In some optional embodiments of the present application, the flexible display assembly 1 further includes a flexible light-shielding sheet 13, which is sandwiched between the flexible display film 11 and the flexible printed circuit board 16. The flexible light-shielding sheet 13 is provided with a plurality of light-transmitting holes 131, each of which is provided with at least one light-emitting element 14, and each light-transmitting area 111 is arranged opposite to at least one light-transmitting hole 131. It should be noted here that, in a specific implementation, the number of light-transmitting holes 131 on the flexible light-shielding sheet 13 may be the same as or different from the number of light-transmitting areas 111 on the flexible display film 11, as long as the use requirements can be met, and this embodiment does not impose any specific restrictions on this. In addition, the shape and size of the light-transmitting holes 131 on the flexible light-shielding sheet 13 may be the same as or different from the shape and size of the corresponding light-transmitting areas 111 on the flexible display film 11, as long as the use requirements can be met, and this embodiment does not impose any specific restrictions on this.

[0079] In this embodiment, the provision of the flexible light shielding sheet 13 can reduce the risk of light leakage in the flexible display assembly 1 while ensuring that the flexible display assembly 1 can still be bent, so that the light emitted by the light-emitting element 14 can be more fully and concentratedly transmitted to the light-transmitting area 111 of the flexible display film 11, thereby facilitating the improvement of the light display effect of the flexible display assembly 1. In particular, in a specific implementation, the flexible light shielding sheet 13 can be made of non-transparent flexible materials such as silicone, rubber, silicone rubber, sponge, etc., as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this. In this embodiment, it should be noted that in some embodiments, the flexible light shielding sheet 13 and the flexible display film 11, as well as the flexible light shielding sheet 13 and the flexible printed circuit board 16, can be laminated together by gluing.

[0080] For further information, please refer to Figure 13 In some optional embodiments of the present application, the flexible display assembly 1 further includes a flexible reflective layer 15 , which is sandwiched between the flexible display film 11 and the flexible printed circuit board 16 , and each light-emitting element 14 is exposed from the flexible reflective layer 15 .

[0081] In this embodiment, the provision of the flexible reflective layer 15 can improve the lighting display effect of the flexible display assembly 1 while ensuring that the flexible display assembly 1 can still be bent. Specifically, in some usage scenarios, after the light emitted by the light-emitting element 14 is irradiated by the light-transmitting area 111 of the flexible display film 11 (or the flexible diffusion film 12), a portion of the light will be reflected. The presence of the flexible reflective layer 15 can, to a certain extent, reflect this partially reflected light back to the light-transmitting area 111 of the flexible display film 11, thereby improving the utilization rate of light and allowing the flexible display assembly 1 to obtain a better lighting display effect. In a specific implementation, the flexible reflective layer 15 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 15), or a reflective ink layer. As long as it can meet the usage requirements, this embodiment does not impose specific restrictions on this. In this embodiment, it should be noted that, in some implementations, the flexible reflective layer 15 and the flexible display film 11 as well as the flexible reflective layer 15 and the flexible printed circuit board 16 can be laminated together by gluing.

[0082] It should be noted that, in the structural design of the flexible display assembly 1 including the flexible display film 11, the flexible diffusion film 12, the flexible light shielding sheet 13, and the flexible reflective layer 15 can be present at the same time, or one or two of them can be selected for setting, which depends on the actual use requirements. This embodiment does not impose any specific restrictions on this. Preferably, in order to obtain a better light display effect, such as Figure 13 As shown, the flexible display film 11, the flexible diffusion film 12, the flexible light shielding sheet 13, the flexible reflective layer 15, and the flexible printed circuit board 16 are stacked in sequence, wherein two adjacent layers can be stacked together by gluing.

[0083] Further, please refer to Figure 2-4In some optional embodiments of the present application, a surface of the flexible printed circuit board 16 facing the flexible display film 11 has a first mounting surface 161 and a second mounting surface 162 that are connected to each other. The area of ​​the first mounting surface 161 is larger than the area of ​​the second mounting surface 162. An edge notch 1D is defined along one edge of the flexible display assembly 1 along its width direction. The portion of the flexible printed circuit board 16 where the second mounting surface 162 is provided is located within the edge notch 1D. Multiple light-emitting elements 14 are fixed to the first mounting surface 161. The second mounting surface 162 is provided with at least one of a current input interface 17 electrically connected to the circuit trace 160, a current driving element 18, and multiple metal test points 19.

[0084] In this embodiment, the provision of the current input interface 17 facilitates the electrical connection between the circuit traces 160 of the flexible printed circuit board 16 and the electronic control assembly 4 of the aerosol generating device. For example, in a specific application, one end of a flexible flat cable can be connected to the current input interface 17 and the other end of the flexible flat cable can be connected to the control circuit board 42 of the electronic control assembly 4. This allows for a quick and convenient electrical connection between the circuit traces 160 of the flexible printed circuit board 16 and the electronic control assembly 4. The current input interface 17 can be a connector similar to the socket 107 or another type of communication interface, as long as it meets the requirements of use. This embodiment does not impose any specific limitations on this.

[0085] In this embodiment, the provision of the current driving element 18 enables, after the electronic control assembly 4 is connected via the current input interface 17, the control circuit board 42 of the electronic control assembly 4 to drive the various light-emitting elements 14 in the flexible display assembly 1 to emit light in a predetermined manner, thereby displaying the desired information on the flexible display film 11. It should be noted that, in a specific implementation, the current driving element 18 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.

[0086] In this embodiment, the provision of multiple metal test points 19 can facilitate testers to perform corresponding functional tests or fault tests on the flexible display assembly 1 .

[0087] In this embodiment, an edge notch 1D is provided on one edge of the flexible display assembly 1 along its width direction (for example, Figure 2As shown, the edge notch 1D is opened on the lower edge of the flexible display component 1), and the second mounting surface 162 for mounting the current input interface 17, the current driving element 18 and the plurality of metal test points 19 in the flexible printed circuit board 16 is exposed and arranged in the edge notch 1D. Compared with the arrangement method of protruding the portion of the flexible printed circuit board 16 with the second mounting surface 162 on the width edge of the flexible display component 1 (as shown in FIG. Figure 12 As shown), in the process of connecting the first end portion 1A and the second end portion 1B of the flexible display component 1, it is possible to effectively avoid the portion of the flexible printed circuit board 16 where the second mounting surface 162 is provided obstructing the connection between the two ends and blocking the partial light-transmitting area 111 of the flexible display film 11, thereby facilitating improvement of the connection convenience between the first end portion 1A and the second end portion 1B and improving the light display effect of the flexible display component 1.

[0088] In this embodiment, it can be understood that if Figure 1-2 The flexible display assembly 1 shown is similar to the Figure 11-12 The main difference between the flexible display assemblies 1 shown is that the shapes and the locations of the second mounting surface 162 of the flexible printed circuit board 16 are different, while the other structures may be the same.

[0089] Correspondingly, please refer to Figure 14-17 An embodiment of the present application further provides an aerosol generating device, which includes a housing 2, an atomizing core 3, an electronic control component 4, and a flexible display component 1 (such as Figure 1-13 shown), where:

[0090] The interior of the shell 2 is provided with an air flow channel 201 and a storage bin 202 for storing aerosol-forming substances. The aerosol-forming substances can be substances such as tobacco oil, liquid medicine, etc., which can be determined according to the actual usage needs of the user. This embodiment does not impose specific restrictions on this.

[0091] The atomizer core 3 is installed in the air flow path of the air flow channel 201 so that the aerosol generated by the atomizer core 3 can be carried away by the air flow formed in the air flow channel 201 and discharged to the outside for inhalation by the user. Moreover, the atomizer core 3 is connected to the storage bin 202 so that the atomizer core 3 can absorb aerosol-forming substances from the storage bin 202 for heating and atomization. It should be noted that the specific structure and working principle of the atomizer core 3 and the communication method between the atomizer core 3 and the storage bin 202 are well known to those skilled in the art and will not be repeated here.

[0092] The flexible display assembly 1 is mounted on the housing 2, with the light-emitting surface 1C of the flexible display assembly 1 facing away from the housing 2. The first end 1A of the flexible display assembly 1 is connected to the second end 1B of the flexible display assembly 1 via a connecting structure 10, so that the flexible display assembly 1 is arranged 360 degrees around the housing 2 along the circumference of the housing 2.

[0093] The electronic control component 4 is installed in the shell 2, and the electronic control component 4 is electrically connected to the flexible display component 1 and the atomizer core 3 respectively. The electronic control component 4 is mainly used to control the flexible display component 1 to display visual information of the aerosol generating device, and to control the working state of the atomizer core 3, such as controlling the atomizer core 3 to work according to a predetermined power or controlling the atomizer core 3 to stop working due to power failure; wherein, in some optional embodiments, the electronic control component 4 may specifically include a battery 41 for providing electrical energy and a control circuit board 42 with a control function. The control circuit board 42 is electrically connected to the atomizer core 3, the flexible display component 1, and the battery 41 respectively. The structural form of the control circuit board 42 can be a single-chip microcomputer, a processor, a controller, or other mature devices with control functions in this field.

[0094] In the technical solution of this embodiment, since the flexible display component 1 is arranged around the shell 2 360 degrees along the circumference of the shell 2, the light-emitting surface 1C of the flexible display component 1 can be distributed on multiple outer surfaces in different orientations along the circumference of the shell 2, so that the aerosol generating device can achieve 360-degree all-round information display. Therefore, compared with the traditional aerosol generating device in which only one outer surface is covered with a display screen, the aerosol generating device provided in this embodiment has a larger information display range and can display more visual information to the user.

[0095] For further information, please refer to Figure 14-17In some optional embodiments of the present application, the shell 2 includes a hollow body shell 21, a top cover 22 with a top surface 220, and a bottom cover 23 with a bottom surface 230. The top cover 22 is provided with a first annular enclosing portion 221 on the side facing away from the top surface 220. The first annular enclosing portion 221 is fixedly sleeved on the outer wall of one end of the body shell 21 along its own height direction (specifically, the first annular enclosing portion 221 and one end of the body shell 21 can be fixed to each other by means of a snap connection, interference fit, etc.). The bottom cover 23 is provided with a second annular enclosing portion 231 on the side facing away from the bottom surface 230. The second annular enclosing portion 231 is fixedly sleeved on the outer wall of one end of the body shell 21 facing away from the top cover 22 (specifically, the first annular enclosing portion 221 and one end of the body shell 21 can be fixed to each other by means of a snap connection, interference fit, etc.). The second annular enclosure portion 231 and the other end of the body shell 21 can be fixed to each other by means of a snap connection, interference fit, etc.), the top cover 22, the body shell 21 and the bottom cover 23 jointly define a mounting groove 203 arranged 360 degrees around the circumference of the shell 2, and the flexible display component 1 is located in the mounting groove 203 and is arranged around the body shell 21; the aerosol generating device also includes a protective shell 5 made of a light-transmitting material (such as glass, acrylic and other light-transmitting materials), the protective shell 5 is enclosed, and one end of the protective shell 5 is sleeved on the outer wall of the first annular enclosure portion 221 and abuts against the top cover 22, and the end of the protective shell 5 facing away from the top cover 22 is sleeved on the outer wall of the second annular enclosure portion 231 and abuts against the bottom cover 23.

[0096] In this embodiment, based on the above structural design, when manufacturing the aerosol generating device, the control circuit board 42 and other components can be first installed in the bottom cover 23; then the bottom cover 23 is fixed to the lower port of the body shell 21; then the battery 41, the atomizer core 3, the components for forming the storage compartment 202, the components for forming the airflow channel 201 and other structures are installed in the body shell 21; then the flexible display assembly 1 is enclosed into a cylindrical structure that adapts to the shape of the body shell 21 and is sleeved on the body shell 21. The flexible display component 1 is arranged to surround the body shell 21, and the flexible display component 1 is electrically connected to the control circuit board 42 through a flexible cable or the like; then the lower end of the protective shell 5 is sleeved on the outer wall of the second annular enclosure portion 231, so that the protective shell 5 surrounds the flexible display component 1; finally, the first annular enclosure portion 221 of the top cover 22 is fixedly matched with the upper end of the body shell 21, and the upper end of the protective shell 5 is sleeved on the outer wall of the first annular enclosure portion 221, so that a complete vapor generation device can be obtained. Among them, the setting of the light-transmitting protective shell 5, on the one hand, can ensure that the user can observe the information displayed by the flexible display component 1 through the protective shell 5, and can protect the flexible display component 1 to reduce the risk of damage to the flexible display component 1 due to impact by foreign objects; on the other hand, it can reduce the installation requirements of the flexible display component 1. Specifically, even if there is a gap between the inner peripheral side of the flexible display component 1 and the outer surface of the body shell 21 (that is, equivalent to the flexible display component 1 not tightly wrapping the body shell 21), under the constraint of the protective shell 5, the flexible display component 1 can also be stably maintained in the installation groove 203 and arranged around the shell 2.

[0097] It should be noted here that other contents of the flexible display assembly 1 and the aerosol generating device disclosed in this application can be found in the prior art and will not be described in detail here.
