[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 power supply component, and a storage chamber. Among them, the storage chamber generally contains aerosol-forming substances. The aerosol-forming substances in the storage chamber can be transferred to the atomizer core through capillary action and other methods. When the user uses the aerosol generating device for inhalation, the power supply component 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, its power supply and the amount of aerosol-forming substance gradually decrease. To facilitate users in readily and intuitively understanding the remaining power and amount of aerosol-forming substance in the aerosol generating device, the aerosol generating device is typically equipped with a display screen capable of displaying information such as the remaining power and amount of aerosol-forming substance.

[0037] Please refer to Figure 1-Figure 5 One embodiment of the present application provides an aerosol generating device comprising a mouthpiece 10, a housing 20, a fixing member 30, a liquid storage assembly 40, an atomizing core 50, a first display assembly 60, a second display assembly 70, a controller 80, and a battery 90. The mouthpiece 10 is connected to the housing 20 for a user to inhale the aerosol. In this embodiment, the housing 20 and the fixing member 30 constitute the housing of the aerosol generating device. Specifically, the housing includes the housing 20 and the fixing member 30. It is understood that the shape and structure of the housing are not specifically limited herein as long as they can accommodate and mount at least some of the components of the aerosol generating device.

[0038] In this embodiment, the housing 20 includes a top cover 201, a bottom cover 202, and a side cover 203. The top cover 201 is connected to the nozzle 10. The first end of the side cover 203 is connected to the top cover 201, and the second end of the side cover 203 is connected to the bottom cover 202.

The top cover 201, the bottom cover 202, and the side cover 203 form a display window 205, which extends through the first side, the second side, and the third side of the housing 20. The second side of the housing 20 is connected to the first side and the third side of the housing 20. Preferably, the top cover 201, the bottom cover 202, and the side cover 203 are integrally formed. Therefore, it is not only easy to assemble and has high production efficiency, but also more reliable in structure.

[0040] The fixing member 30 is located within the housing 20 and between the top cover 201 and the bottom cover 202. That is, the fixing member 30 is located within the space formed by the housing 20 and is connected to the top cover 201. The cooperation between the fixing member 30 and the housing 20 not only facilitates the assembly of the first display assembly 60 and the second display assembly 70, thereby improving production efficiency, but also makes the structure more stable and reliable.

[0041] Preferably, the aerosol generating device also includes a support seat 91, and the fixing member 30 is a fixing tube, that is, the fixing member 30 has a tubular structure. The first end of the fixing tube is connected to the top cover 201, and the second end of the fixing tube is connected to the support seat 91. A fixing groove 301 is provided on the side of the fixing tube, and the fixing groove 301 is provided with a positioning protrusion 302. The fixing tube is also provided with a receiving hole 305, an avoidance hole 306, a second buckling portion 307 and a second guide portion 308, and the receiving hole 305 and the avoidance hole 306 are located on the side wall of the fixing tube. The first buckling portion 2031 passes through the avoidance hole 306 and is buckled and connected to the second buckling portion 307, so that the fixing member 30 can be tightly connected to the housing 20. The first guide portion 2032 is matched with the second guide portion 308, so that the first buckling portion 2031 and the second buckling portion 307 can be better aligned, which is convenient for assembly and improves production efficiency.

[0042] In this embodiment, the second buckle portion 307 is the tube wall of the fixed tube, and the second guide portion 308 is a guide groove extending laterally along the fixed tube. The support seat 91 is located between the fixed tube and the bottom cover 202. Specifically, the fixed tube includes a tube body portion 303, and the fixing groove 301 is located on the side of the tube body portion 303. One end of the tube body portion 303 facing the top cover 201 extends along the direction of the center line of the tube body portion 303 to form an end wall portion 304, and the second guide portion is located at the end wall portion 304, and the end wall portion 304 abuts against the top cover 201, so that the overall structure is more reliable. In one embodiment, the support seat 91 may not be required, and the second end of the fixing member 30 is connected to the bottom cover 202. The fixing member may be in the shape of a plate or an open ring, etc.

[0043] The liquid storage assembly 40 includes a liquid storage tube 401, a first elastic sealing seat 402, and a second elastic sealing seat 403. The liquid storage tube 401 is located within the tube body 303. A porous liquid-absorbing column 404 is inserted into the liquid storage tube 401. The porous liquid-absorbing column 404 is used to absorb the aerosol-generating substrate. The porous liquid-absorbing column 404 can be porous foam or fiber, as long as it can absorb the aerosol-generating substrate. The first elastic sealing seat 402 is positioned over the first end of the tube body 303 and elastically abuts the end wall 304, thereby improving sealing performance. The second elastic sealing seat 403 is positioned over the second end of the tube body 303 and is connected to the support seat 91.

[0044] The atomizing core 50 includes a liquid guide 501 and an electric heating element 502. The liquid guide 501 is located in the porous liquid absorbing column 404 and is used to conduct the aerosol generating matrix in the porous liquid absorbing column 404 to the electric heating element 502. The liquid guide 501 can be made of materials such as cotton or porous ceramics, as long as it can adsorb the aerosol generating matrix. It is understandable that the aerosol generating matrix can be formed by combining propylene glycol, glycerol and flavors and fragrances in a certain ratio. The aerosol generating matrix is ​​a prior art and its composition is not described here. The electric heating element 502 is electrically connected to the controller 80. The controller 80 is electrically connected to the battery 90 to control the battery 90 to power the electric heating element 502, so that the electric heating element 502 generates heat to atomize the aerosol generating matrix to form an aerosol. Among them, the electric heating element 502 can be an electric heating net or an electric heating wire. It is understandable that the structure of the atomizing core 50 is not specifically limited herein, as long as it can atomize the aerosol-generating substrate to form an aerosol.

[0045] Both the first display assembly 60 and the second display assembly 70 are mounted on the housing. This means that the first display assembly 60 and the second display assembly 70 can be mounted on the outer surface of the housing or within the housing, and the space formed within the housing also falls within the scope of the housing. In this embodiment, the first display assembly 60 is disposed along the circumference of the fixed tube, surrounding the outer circumference of the fixed tube. The first display assembly 60 can be used to display information related to the aerosol generating device parameters and patterns such as stars, moons, suns, and rockets to enhance the aesthetics of the electronic cigarette. For example, it can be used to display the remaining battery level of the aerosol generating device, the remaining amount of aerosol-forming material, operating power, and preset pattern information. In this embodiment, the first display assembly 60 is a flexible, bendable display assembly, i.e., a flexible display screen, such as a flexible OLED screen or a flexible LCD screen. The first display assembly 604 can be secured to the outer surface of the fixed tube by gluing, snapping, or other means. The first display assembly 60 can be in an O-shaped or U-shaped configuration, and its shape is not specifically limited herein.

[0046] One end of the first display assembly 60 and the second display assembly 70 are located on the same side of the housing, that is, one end of the first display assembly 60 and the second display assembly 70 are located on the same side of the aerosol generating device. The image displayed by the second display assembly 70 and at least part of the image displayed by the first display assembly 60 are located on the same side of the aerosol generating device. Therefore, the image displayed by the first display assembly 60 and the image displayed by the second display assembly 70 can be combined to form an integrated image. The resolution of the first display assembly 60 is different from that of the second display assembly 70. Therefore, by cooperating with the first display assembly 60, the second display assembly 70 can display certain images at a low cost.

[0047] It is understood that as long as at least a portion of the first display assembly 60 and at least a portion of the second display assembly 70 are located on the same side of the housing, that is, at least a portion of the first display assembly 60 and at least a portion of the second display assembly 70 are located on the same side of the aerosol generating device, the spacing and positional relationship between the two are not specifically limited herein. For example, when the housing is a polyhedron, at least a portion of the image displayed by the first display assembly 60 and at least a portion of the image displayed by the second display assembly 70 are located on the same side of the housing; when the housing is a rotating body, at least a portion of the image displayed by the first display assembly 60 and at least a portion of the image displayed by the second display assembly 70 are located in the same area of ​​the housing, so that when a user views the housing, at least a portion of the image formed by the combination of the first display assembly 60 and the second display assembly 70 can be seen. Therefore, as long as at least a portion of the image formed by the combination of the first display assembly 60 and the second display assembly 70 can be seen when a user views the housing, at least a portion of the first display assembly 60 and at least a portion of the second display assembly 70 are considered to be located on the same side of the housing.

[0048] Preferably, the pixel pitch of the second display component 70 is smaller than the pixel pitch of the first display component 60, and the resolution of the second display component 70 is greater than the resolution of the first display component 60. The second display component 70 displays images with better smoothness and detail. Therefore, the second display component 70 can be used to display images of the rapidly moving sun or earth, while the first display component 60 can be used to display images of other planets or satellites that are slowly moving around the sun or earth. Thus, not only are the advantages of the first and second display components 60 and 70 utilized, but costs are also significantly reduced. Furthermore, the first and second display components 60 and 70 can be combined to display fountains, sprays, or fireworks, for example. The second display component 70 can be a rigid liquid crystal display or an organic light-emitting diode display, for example. The second display component 70 is inserted into the receiving hole 305, thereby ensuring reliable positioning. It is understood that pixel pitch refers to the distance between two adjacent pixels on a display screen.

[0049] The first display assembly 60 is provided with a screen-matching notch 600 and a positioning notch 601. The position of the screen-matching notch 600 corresponds to the position of the light-transmitting area 204. This allows the first display assembly 60 to fit more closely with the second display assembly 70, allowing the images displayed by the first display assembly 60 to be better integrated with the images displayed by the second display assembly 70, thereby improving the display effect. The positioning protrusion 302 is inserted into the positioning notch 601, making it less likely to shift during assembly, which not only facilitates assembly but also improves product yield.

[0050] Please refer to Figures 6 to 9 In this embodiment, the first display assembly 60 is a bendable flexible display assembly disposed around the side of the fixing member 30. The first display assembly 60 includes a flexible printed circuit board 1, a plurality of light-emitting elements 2, and a flexible display layer 3. The flexible printed circuit board 1 is wrapped around the side of the fixing member 30, that is, the flexible printed circuit board is wrapped around the side of the fixing tube, and the flexible printed circuit board is inserted into the fixing groove 301. Therefore, it is not only convenient for assembly, but also easy to fit in place, improving production efficiency.

[0051] The flexible printed circuit board 1 has circuit traces 14 and a first surface 11 along its thickness. A plurality of light-emitting elements 2 are spaced apart and electrically connected to the circuit traces 14 on the first surface 11 of the flexible printed circuit board 1. A flexible display layer 3 is fixedly laminated on the first surface 11 of the flexible printed circuit board 1 and covers each of the light-emitting elements 2. The flexible display layer 3 corresponds to the position of the display window 205. The flexible display layer 3 has a plurality of light-transmitting regions 31, each of which is disposed opposite at least one light-emitting element 2. The areas of the flexible display layer 3 other than the light-transmitting regions 31 are light-shielding regions 32.

[0052] In this embodiment, those skilled in the art will understand that the flexible printed circuit board 1, also known as an FPC (Flexible Printed Circuit, FPC) board, is a flexible circuit board printed with circuit tracks 14, which has the advantages of good flexibility, light weight, and thin thickness. In a specific manufacturing process, the required flexible printed circuit board 1 can be obtained by printing the circuit tracks 14 on a flexible film, wherein the flexible film can be a polymer material with high performance (such as excellent heat resistance, chemical stability and flexibility) such as polyimide film and polyester film.

[0053] In this embodiment, the light-emitting element 2 can be a component that can emit light when powered, such as an LED lamp bead. In some optional embodiments, the light-emitting element 2 can be an LED lamp bead with dimensions of 0.5-1.5 mm in length, 0.2-0.8 mm in width, and 0.1-0.8 mm in thickness. Preferably, the light-emitting element 2 can be a model 0402 LED lamp bead, which has dimensions of 1.0 mm in length, 0.5 mm in width, and 0.4 mm in thickness. After repeated testing, when the first display assembly 60 provided in this embodiment uses this model of LED lamp bead as the light-emitting element 2, the first display assembly 60 can achieve better display effects and higher quality reliability than LED lamp beads of other dimensions. The light-emitting element 2 can be fixed to the first surface 11 of the flexible printed circuit board 1 by welding, bonding (e.g., bonding with insulating glue or conductive glue), etc., and is electrically connected to the circuit traces 14 of the flexible printed circuit board 1.

[0054] In this embodiment, the material of the flexible display layer 3 can be a flexible material such as polyimide (PI), polyethylene terephthalate (PET), polyethylene phthalate (PEN), liquid crystal polymer (LCP), polyvinyl alcohol (PVA), polydimethylsiloxane (PDMS), etc., as long as it can meet the use requirements. This embodiment does not impose any specific restrictions on the specific material of the flexible display layer 3. Among them, when the flexible display layer 3 is made of a transparent flexible material, a light-transmitting area 31 and a light-shielding area 32 can be formed on the flexible display layer 3 by applying a light-shielding ink or the like. For example, when the flexible display layer 3 is a transparent polyimide film, a light-shielding ink can be applied to the surface of the polyimide film in a predetermined manner. The area of ​​the polyimide film coated with the light-shielding ink can be regarded as the light-shielding area 32 of the flexible display layer 3, and the area of ​​the polyimide film not coated with the light-shielding ink can be regarded as the light-transmitting area 31 of the flexible display layer 3. When the flexible display layer 3 is made of an opaque flexible material, a light-transmitting area 31 and a light-blocking area 32 can be formed on the flexible display layer 3 by laser engraving or the like. For example, when the flexible display layer 3 is an opaque PET film, the required light-transmitting area 31 can be engraved on the surface of the PET film by laser engraving (the light-transmitting area 31 at this time is essentially a through hole), and the unengraved area in the PET film is formed as the light-blocking area 32.

[0055] It should be noted here that, in specific implementation, the shape, size, and position distribution of each light-transmitting area 31 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 31 can be a text shape, a number shape, a letter shape, a dot shape, a line shape, etc. When the light emitted by the light-emitting element 2 reaches the light-transmitting area 31, light display information of the corresponding shape can be displayed. For example, when the light emitted by the light-emitting element 2 reaches the light-transmitting area 31 in the shape of a letter, the user can observe the illuminated letter on the flexible display layer 3. In this way, by combining multiple light-transmitting areas 31 of different shapes, light display information of multiple different shapes can be obtained, and light display information of different shapes can be used to represent various information of the aerosol generating device (such as remaining power, working power, remaining amount of aerosol-forming substance, preset pattern, etc.). In addition, the number of light-emitting elements 2 corresponding to each light-transmitting area 31 can also be determined according to actual use requirements, and this embodiment does not impose specific restrictions on this.

[0056] In this embodiment, it should be noted that, in a specific implementation, the flexible display layer 3 can be fixedly laminated on the first surface 11 of the flexible printed circuit board 1 by bonding or the like. Optionally, Figure 7As shown, a third adhesive layer 33 is provided on the surface of the flexible display layer 3 facing the flexible printed circuit board 1. The flexible display layer 3 can be quickly and reliably adhered to the flexible printed circuit board 1 through the third adhesive layer 33 to form an integrated laminated structure. In a specific implementation, the third adhesive layer 33 can be double-sided tape, structural adhesive, optically transparent adhesive, pressure-sensitive adhesive, etc., as long as it can meet the use requirements. This embodiment does not impose any specific restrictions on this.

[0057] In the technical solution provided in the embodiment of the present application, a plurality of light-emitting elements 2 are distributed on the first surface 11 of the flexible printed circuit board 1, and a flexible display layer 3 having a plurality of light-transmitting areas 31 is fixed on the first surface 11 of the flexible printed circuit board 1 and covers each light-emitting element 2, so that the plurality of light-emitting elements 2 can be encapsulated between the flexible display layer 3 and the flexible printed circuit board 1, wherein the flexible printed circuit board 1 can be used as a mounting carrier for the plurality of light-emitting elements 2, and the circuit traces 14 on the flexible printed circuit board 1 can be used as a medium for electrically connecting the plurality of light-emitting elements 2 to a power source. When the plurality of light-emitting elements 2 are connected to the battery through the circuit traces 14 of the flexible printed circuit board 1, the plurality of light-emitting elements 2 are powered on and emit light, and the emitted light can be displayed in the light-transmitting area 31 of the flexible display layer 3, that is, the light-transmitting area 31 of the flexible display layer 3 can be used as the light display area of ​​the first display component 60, thereby realizing the display function of the first display component 60.

[0058] Since the flexible display layer 3 and the flexible printed circuit board 1 are both flexible structures, the first display component 60 formed by laminating the flexible display layer 3 and the flexible printed circuit board 1 is also a flexible structure, so it can be bent. In this way, based on the bendable characteristics of the first display component 60, the first display component 60 can be covered on the outer peripheral surface of the fixed tube by winding, so that the light display area of ​​the first display component 60 can be distributed on multiple outer surfaces of the aerosol generating device, thereby increasing the display area of ​​the aerosol generating device, so that the aerosol generating device can display more information to the user.

[0059] Please refer to Figure 8 In some optional embodiments of the present application, the first display assembly 60 further includes a first adhesive layer 15. The flexible printed circuit board 1 further includes a second surface 12 disposed opposite the first surface 11. The first adhesive layer 15 is disposed on the second surface 12 and adhered to the fixing tube. Thus, in some scenarios where the first display assembly 60 of this embodiment is used in an aerosol generating device, the entire first display assembly 60 can be quickly attached to the outer surface of the fixing tube via the first adhesive layer 15, thereby facilitating easier installation of the first display assembly 60. In specific implementations, the first adhesive layer 15 can be a double-sided adhesive, structural adhesive, or other type of adhesive, as long as it meets the requirements of use. This embodiment does not impose any specific limitations on this.

[0060] Please refer to Figure 6 and Figure 9 In some optional embodiments of the present application, the first display component 60 further includes a current driving element 41 and a current input interface 42. The first surface 11 has a first mounting area 111 and a second mounting area 112 that are connected to each other. The area of ​​the first mounting area 111 is larger than the second mounting area 112. The second mounting area 112 is located at the edge of the flexible printed circuit board 1 (for example, assuming that the flexible printed circuit board 1 is a strip-shaped sheet with a certain length and width, the second mounting area 112 can be located at the length edge or the width edge of the flexible printed circuit board 1). A plurality of light-emitting elements 2 are fixed on the first mounting area 111, and the current driving element 41 and the current input interface 42 are installed at intervals on the second mounting area 112 and are both electrically connected to the circuit trace 14.

[0061] In this embodiment, by providing a current input interface 42 electrically connected to the circuit trace 14, in some scenarios where the first display assembly 60 of this embodiment is used in an aerosol generating device, it is convenient to electrically connect each light-emitting element 2 in the first display assembly 60 to the controller of the aerosol generating device. For example, in a specific application, only one end of a wire needs to be connected to the current input interface 42, and the other end of the wire needs to be connected to the controller of the aerosol generating device. In this way, the electrical connection between each light-emitting element 2 and the controller of the aerosol generating device can be quickly established, which is very convenient. The structure of the current input interface 42 can be a universal connector or other type of communication interface, as long as it meets the usage requirements, and this embodiment does not impose specific limitations on this.

[0062] In this embodiment, by providing a driving element electrically connected to the circuit trace 14, in some scenarios where the first display assembly 60 of this embodiment is applied to an aerosol generating device, when the power supply assembly of the aerosol generating device is connected via the current input interface 42, the power supply assembly can drive each light-emitting element 2 to emit light in a preset manner, thereby displaying the desired information on the flexible display layer 3. It should be noted that, in a specific implementation, the driving element can utilize 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.

[0063] Please refer to Figure 6 、 Figure 9-10 as well as Figure 14In some optional embodiments of the present application, an avoidance notch 13 is provided at the edge of the flexible printed circuit board 1, and the second mounting area 112 is located within the avoidance notch 13. The area of ​​the first surface 11 of the flexible printed circuit board 1 other than the second mounting area 112 is the first mounting area 111. This arrangement is more convenient than the arrangement in which the second mounting area 112 of the flexible printed circuit board 1 is protruded from the edge of the flexible printed circuit board 1 (e.g., Figure 11 As shown), in some use scenarios where the first display component 60 of this embodiment is applied to an aerosol generating device, it is beneficial to reduce the risk of interference between the first installation area 111 and the second installation area 112 during the process of installing the first display component 60 on the outer surface of the aerosol generating device along the circumference of the aerosol generating device, thereby facilitating the increase of the display area of ​​the first display component 60 in the circumferential direction of the aerosol generating device. For example, assuming that the first display component 60 is a flexible strip sheet with a certain length and width, if the second installation area 112 of the flexible printed circuit board 1 is protruded on one of the width edges of the flexible printed circuit board 1 (as shown in FIG. Figure 7 As shown in FIG, in the process of installing the strip-shaped first display component 60 on the outer surface of the aerosol generating device in a surrounding manner along the circumference of the aerosol generating device, the second mounting area 112 of the flexible printed circuit board 1 easily overlaps with the other width edge of the flexible printed circuit board 1 and interferes with the end of the first mounting area 111 away from the second mounting area 112, making it difficult for the first display component 60 to form a complete closed-loop structure, which is not conducive to maximizing the display area of ​​the aerosol generating device along its circumference.

[0064] In the technical solution provided in this embodiment, the second mounting area 112 of the flexible printed circuit board 1 is designed to be avoided, that is, the second mounting area 112 of the flexible printed circuit board 1 is located in the avoidance gap 13 opened at the edge of the flexible printed circuit board 1. In this way, in the process of installing the first display component 60 on the outer surface of the aerosol generating device along the circumference of the aerosol generating device, the end of the first mounting area 111 away from the second mounting area 112 can be effectively avoided from interfering with the second mounting area 112, so that the first display component 60 can be easily enclosed into an open ring or a complete closed loop structure, which is conducive to maximizing the display area of ​​the aerosol generating device along its circumference.

[0065] In this embodiment, it should be noted that in some specific application scenarios, when the flexible printed circuit board 1 is a strip sheet with a certain length and width, an avoidance gap 13 ( Figure 9-10As shown in FIG, an avoidance gap 13 for accommodating the second mounting area 112 may also be opened on the width edge of the flexible printed circuit board 1, and this embodiment does not impose any specific limitation on this.

[0066] Please refer to Figure 9 In some optional embodiments of the present application, the second mounting area 112 of the flexible printed circuit board 1 is also provided with a plurality of metal test points 43 , which are electrically connected to the circuit traces 14 of the flexible printed circuit board 1 . The provision of the plurality of metal test points 43 facilitates functional testing or fault testing of the first display assembly 60 by testers.

[0067] Please continue to refer to Figure 9 In some optional embodiments of the present application, the first display assembly 60 further includes a flexible flat cable 52, one end of which is plugged into the current input interface 42. This configuration facilitates the installation personnel to quickly and electrically connect the first display assembly 60 to the power supply assembly of the aerosol generating device when the first display assembly 60 of this embodiment is used in the aerosol generating device. During operation, the installer only needs to plug the end of the flexible flat cable 52 away from the current input interface 42 into the communication interface of the power supply assembly, which is very convenient.

[0068] Please refer to Figure 9-10 In some optional embodiments of the present application, the first display assembly 60 further includes a metal sheet 51, which is fixed to the side of the flexible membrane facing away from the second mounting area 112. In this embodiment, the metal sheet 51 can reinforce (i.e., provide additional strength to) the portion of the flexible printed circuit board 1 containing the second mounting area 112, thereby facilitating positioning of the portion of the flexible printed circuit board 1 where the driving element and the current input interface 42 are mounted in some usage scenarios where the first display assembly 60 of this embodiment is mounted on the outer surface of an aerosol generating device. Specifically, in order to more conveniently position the portion of the flexible printed circuit board 1 where the driving element and the current input interface 42 are mounted, at least one positioning hole 511 is further provided on the surface of the metal sheet 51.

[0069] Please refer to Figure 8In some optional embodiments of the present application, the first display assembly 60 further includes a flexible reflective layer 6, which covers the first surface 11 of the flexible printed circuit board 1, with each light-emitting element 2 exposed from the flexible reflective layer 6. In this embodiment, the provision of the flexible reflective layer 6 can enhance the lighting display effect of the first display assembly 60 while ensuring that the first display assembly 60 is bendable. Specifically, after the light emitted by the light-emitting element 2 hits the light-transmitting region 31 of the flexible display layer 3, a portion of the light is reflected. The presence of the flexible reflective layer 6 can, to a certain extent, reflect this partially reflected light back to the light-transmitting region 31 of the flexible display layer 3, thereby improving light utilization and enabling the first display assembly 60 to achieve a better lighting display effect. In a specific implementation, the flexible reflective layer 6 can be a flexible reflective film (such as a transparent polyimide film), a paint layer (optionally, a white paint layer can be used as the flexible reflective layer 6 to achieve a better reflective effect), or a reflective ink layer. Any suitable material that meets the requirements of use is not specifically limited in this embodiment.

[0070] Please continue to refer to Figure 8 、 Figure 12 and Figure 13 In some optional embodiments of the present application, the first display component 60 further includes a flexible diffusion layer 7. The flexible diffusion layer 7 can be attached to the surface of the flexible display layer 3 facing the flexible printed circuit board 1 by means of glue or the like, and the flexible diffusion layer 7 covers each light-transmitting area 31. In this embodiment, by providing the flexible diffusion layer 7 between the multiple light-emitting elements 2 and the multiple light-transmitting areas 31, the flexible diffusion layer 7 can evenly diffuse the light emitted by the light-emitting elements 2, so that the light emitted by the light-emitting elements 2 can be more evenly diffused to the light-transmitting areas 31 of the flexible display layer 3, thereby improving the uniformity of the light display of the first display component 60. In a specific implementation, the flexible diffusion layer 7 can be a transparent flexible film coated with fluorescent ink, or other types of flexible diffusion films, as long as they can meet the requirements of use. This embodiment does not impose specific restrictions on this. Optionally, in some embodiments, the flexible diffusion layer 7 is a yellow fluorescent ink film sheet, and the light emitted by the light-emitting elements 2 is blue light. Optionally, in some embodiments, a fourth adhesive layer 71 is provided on the surface of the flexible diffusion layer 7 facing away from the flexible display layer 3 so that the flexible diffusion layer 7 is adhered to the flexible printed circuit board 1 (or the flexible reflective layer 6, or the flexible shading layer 8 described later), wherein the fourth adhesive layer 71 can be a glue layer of the type of double-sided tape, structural adhesive, etc.

[0071] Please continue to refer to Figure 8 and Figure 14In some optional embodiments of the present application, the first display component 60 further includes a flexible light-shielding layer 8, which is provided with a plurality of light-transmitting holes 81. The flexible light-shielding layer 8 is sandwiched between the flexible printed circuit board 1 and the flexible display layer 3, and each light-transmitting hole 81 is arranged opposite to at least one light-transmitting area 31. In this embodiment, the provision of the flexible light-shielding layer 8 can reduce the loss of light emitted by the light-emitting element 2, so that the light emitted by the light-emitting element 2 can be more fully and concentratedly transmitted to the light-transmitting area 31 of the flexible display layer 3, thereby facilitating the improvement of the light display effect of the first display component 60. In a specific implementation, the flexible light-shielding layer 8 can be made of a non-transparent flexible material such as silicone, rubber, or silicone rubber, as long as it can meet the use requirements. This embodiment does not impose any specific restrictions on this.

[0072] Please continue to refer to Figure 8 In some optional embodiments of the present application, a second adhesive layer 82 is provided on the surface of the flexible light-shielding layer 8 facing the flexible printed circuit board 1. Thus, by providing the second adhesive layer 82, the flexible light-shielding layer 8 can be quickly laminated onto the first surface 11 of the flexible printed circuit board 1 or onto the flexible reflective layer 6. In a specific implementation, the second adhesive layer 82 can be a double-sided adhesive, structural adhesive, or other type of glue, as long as it meets the requirements of use, and this embodiment does not impose any specific restrictions on this.

[0073] Based on the bendable property of the first display component 60, the first display component 60 can simultaneously cover multiple outer surfaces of the fixing member 30 in a winding manner, so that the light display area of ​​the first display component 60 can be distributed on multiple outer surfaces of the aerosol generating device, thereby increasing the display area of ​​the aerosol generating device and enabling the aerosol generating device to display more information to the user.

[0074] The aerosol generating device of the present invention further includes a light-transmitting protective cover 92, which covers the display window 205 and is connected to the housing 20. The light-transmitting protective cover 92 protects the portion of the first display assembly 60 located in the display window 205 area, preventing the user from touching the first display assembly 60. Preferably, the light-transmitting protective cover 92 is detachably connected to the housing 20. More preferably, the light-transmitting protective cover 92 is detachably connected to the housing 20 by snap-fitting.

[0075] In this embodiment, thanks to the above-mentioned improvements, the aerosol generating device of this embodiment has the advantage of a large display area, capable of displaying more visual information to the user. It should be noted that, in a specific implementation, the first display assembly 60 can be arranged around the outer housing 209 in a semi-encircling manner (in which case the first display assembly 60 can be enclosed in an open loop such as a "U" shape) or a fully encircling manner (in which case the first display assembly 60 can be enclosed in a closed loop such as an "O" shape) along the circumference of the outer housing 209. The specific encircling manner of the first display assembly 60 can be determined based on actual usage requirements and is not specifically limited in this embodiment.

[0076] In summary, since at least a portion of the first display assembly 60 and at least a portion of the second display assembly 70 are located on the same side of the housing, they can be combined to display graphic information. Therefore, the image displayed by the first display assembly 60 and the image displayed by the second display assembly 70 can be combined to form a complete image. Since the resolution of the first display assembly 60 and the resolution of the second display assembly 70 are different, the clever combination of the two can display rich, specific images, reduce costs, and facilitate widespread application.

[0077] It should be noted here 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.

[0078] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application.
