[0002] An aerosol generator is an electronic device that atomizes stored aerosol-forming substances such as e-liquid or liquid medication into aerosols through electric heating. Currently, commercially available aerosol generators typically include a housing, protective cover, atomizer core, power supply unit, and liquid reservoir. The protective cover is connected to the housing and forms a storage space within which the atomizer core, power supply unit, and liquid reservoir are located. The liquid reservoir generally contains the aerosol-forming substance, which is conducted to the atomizer core via capillary action. During vaping, the power supply unit provides electricity to the atomizer core, causing it to heat up. This heat atomizes the aerosol-forming substance on the atomizer core into an inhalable aerosol.

[0036] Please refer to Figures 1-5 This application provides an aerosol generating device, comprising a nozzle 10, a housing 20, a fixing member 30, a liquid storage component 40, an atomizing core 50, a first display component 60, a second display component 70, a controller 80, and a battery 90. The nozzle 10 is connected to the housing 20 and is used for users to inhale aerosols. A sealing plug 101 is inserted into the nozzle 10; the user can remove the sealing plug 101 to inhale the aerosol during use. In this embodiment, the housing 20 and the fixing member 30 constitute the shell of the aerosol generating device; that is, the shell includes the housing 20 and the fixing member 30. It is understood that as long as it can accommodate and install at least some of the components of the aerosol generating device, the shape and structure of the shell are not specifically limited here.

[0037] In this embodiment, the outer casing 20 includes a top cover 201, a bottom cover 202, and a side cover 203. The top cover 201 is connected to the suction 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 side cover 203 is provided with an alignment arm 2031, a fastening hole 2032, and a mating groove 2033. The alignment arm 2031 is located within the space formed by the side cover 203. The mating groove 2033 is located on the inner wall surface of the side cover 203 and extends laterally along the outer casing 20. Specifically, the upper and lower ends of the two opposite side walls of the side cover 203 are provided with fastening holes 2032 and mating grooves 2033, thus making the connection more stable and reliable.

[0038] The side cover 203 also has a disc-shaped light-transmitting area 204, which is located on the first side of the housing 20. It is understood that the light-transmitting area 204 can be made of transparent or translucent material, and its shape can be set as needed. The first side and the third side of the housing 20 are positioned opposite each other. The top cover 201 and the bottom cover 202 are positioned opposite each other and located at opposite ends of the housing 20. The top cover 201, bottom cover 202, and side cover 203 form a display window 205, which extends through the first, second, and third sides of the housing 20. The second side of the housing 20 is connected to the first and third sides of the housing 20, and the mating groove 2031 extends to the window of the display window 205. Preferably, the top cover 201, bottom cover 202, and side cover 203 are integrally molded, thus facilitating assembly, increasing production efficiency, and improving structural reliability.

[0039] The fastener 30 is located inside the housing 20 and between the top cover 201 and the bottom cover 202, that is, the fastener 30 is located within the space formed by the housing 20 and is connected to the top cover 201. Through the cooperation between the fastener 30 and the housing 20, it is not only convenient to assemble the first display component 60 and the second display component 70, thus improving production efficiency, but also the structure is more stable and reliable.

[0040] Preferably, the aerosol generating device further includes a support base 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 base 91. A fixing groove 301 is provided on the side of the fixing tube, and a positioning protrusion 302 is provided in the fixing groove 301. The fixing tube is also provided with a receiving hole 305 and an alignment hole 306, which are located on the side wall of the fixing tube. The alignment arm 2031 is inserted into the alignment hole 306, so that the fixing member 30 can be tightly connected to the outer shell 20.

[0041] In this embodiment, the support base 91 is located between the fixing tube and the bottom cover 202. Specifically, the fixing tube includes a tube body 303, and a fixing groove 301 is located on the side of the tube body 303. An end wall 304 extends from the end of the tube body 303 facing the top cover 201 along the direction of the center line of the tube body 303, and the end wall 304 abuts against the top cover 201, thus making the overall structure more reliable. In one embodiment, the support base 91 may not be necessary, and the second end of the fixing member 30 is connected to the bottom cover 202. The fixing member may be plate-shaped or open ring-shaped, etc.

[0042] 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 inside the tube body 303, and a porous liquid absorption column 404 is inserted inside the liquid storage tube 401. The porous liquid absorption column 404 is used to adsorb the aerosol generation matrix. The porous liquid absorption column 404 can be porous foam or fiber, as long as it can adsorb the aerosol generation matrix. The first elastic sealing seat 402 is covered on the first end of the tube body 303 and elastically abuts against the end wall 304, thereby improving the sealing performance. The second elastic sealing seat 403 is covered on the second end of the tube body 303 and connected to the support seat 91.

[0043] The atomizing core 50 includes a liquid guiding component 501 and a heating element 502. The liquid guiding component 501 is located within the porous liquid absorption column 404 and is used to conduct the aerosol generating matrix within the porous liquid absorption column 404 to the heating element 502. The liquid guiding component 501 can be made of materials such as cotton or porous ceramics, as long as it can absorb the aerosol generating matrix. It is understood that the aerosol generating matrix can be formed by combining propylene glycol, glycerol, and fragrance in a certain proportion. The aerosol generating matrix is ​​existing technology, and its composition will not be elaborated here. The heating element 502 is electrically connected to the controller 80. The controller 80 is electrically connected to the battery 90 and is used to control the battery 90 to supply power to the heating element 502, causing the heating element 502 to heat up and atomize the aerosol generating matrix to form an aerosol. The heating element 502 can be a heating mesh or heating wire, etc. Understandably, the structure of the atomizing core 50 is not specifically limited here, as long as it can atomize the aerosol generation matrix to form an aerosol.

[0044] Both the first display component 60 and the second display component 70 are mounted on the housing, meaning they can be installed on the outer surface of the housing or inside the housing. The space formed inside the housing also falls under the category of the housing. In this embodiment, the first display component 60 is arranged circumferentially around the outer surface of the fixed tube. The first display component 60 can be used to display relevant parameter information of the aerosol generating device and to display patterns such as stars, moons, suns, and rockets to enhance the aesthetics of the electronic cigarette. For example, it can display the remaining battery power of the aerosol generating device, the remaining amount of aerosol-forming material, the operating power, and preset pattern information. In this embodiment, the first display component 60 is a flexible display component, i.e., a flexible display screen, such as a flexible OLED screen or a flexible LCD screen. The first display component 604 can be fixed to the outer surface of the fixed tube by means of adhesive, snap-fit, etc. The first display component 60 can be O-shaped or U-shaped, etc., and its shape is not specifically limited here.

[0045] One end of the first display component 60 and the second display component 70 are located on the same side of the housing, that is, one end of the first display component 60 and the second display component 70 are located on the same side of the aerosol generating device. The image displayed by the second display component 70 and at least a portion of the image displayed by the first display component 60 are located on the same side of the aerosol generating device. Therefore, the images displayed by the first display component 60 and the second display component 70 can be combined to form a complete image. The resolutions of the first display component 60 and the second display component 70 are different. Therefore, by cooperating with the second display component 70 and the first display component 60, certain images can be displayed at a low cost.

[0046] It is understood that as long as at least a portion of the first display component 60 and at least a portion of the second display component 70 are located on the same side of the housing, that is, at least a portion of the first display component 60 and at least a portion of the second display component 70 are located on the same side of the aerosol generating device, the spacing and positional relationship between them are not specifically limited here. For example, when the housing is a polyhedron, at least a portion of the image displayed by the first display component 60 and at least a portion of the image displayed by the second display component 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 component 60 and at least a portion of the image displayed by the second display component 70 are located in the same area of ​​the housing, so that when the user views, at least a portion of the image formed by the combination of the first display component 60 and the second display component 70 can be seen. Therefore, as long as the user can see at least a portion of the image formed by the combination of the first display component 60 and the second display component 70, it is considered that at least a portion of the first display component 60 and at least a portion of the second display component 70 are located on the same side of the housing.

[0047] Preferably, the pixel pitch of the second display component 70 is smaller than that of the first display component 60, and the resolution of the second display component 70 is greater than that of the first display component 60. The second display component 70 displays images with better smoothness and detail. Therefore, it can be used to display images of fast-moving objects such as the sun or the earth, while the first display component 60 can be used to display images of other planets or satellites orbiting the sun or the earth at a slower pace. Thus, it not only leverages the advantages of both the first display component 60 and the second display component 70 but also significantly reduces costs. Furthermore, the first display component 60 and the second display component 70 can be combined to display fountains, sprays, or fireworks. The second display component 70 can be a rigid liquid crystal display or an organic light-emitting diode display, etc., and is inserted into the receiving hole 305, ensuring reliable positioning. It is understood that pixel pitch refers to the distance between two adjacent pixels on the display screen.

[0048] The first display component 60 is provided with a screen mating notch 600 and a positioning notch 601. The position of the screen mating notch 600 corresponds to the position of the light-transmitting area 204, thus allowing the first display component 60 and the second display component 70 to fit together more tightly. This enables the images displayed by the first display component 60 and the second display component 70 to blend better, improving the display effect. The positioning protrusion 302 is inserted into the positioning notch 601, making it less prone to displacement during assembly. This not only facilitates assembly but also improves the product yield.

[0049] Please refer to Figures 6 to 9 In this embodiment, the first display component 60 is a flexible display component that can be bent. The flexible display component is disposed around the side of the fixing member 30. The first display component 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 covers the side of the fixing member 30, that is, the flexible printed circuit board covers the side of the fixing tube, and the flexible printed circuit board is inserted into the fixing groove 301. Therefore, it is not only easy to assemble, but also easy to assemble into place, thus improving production efficiency.

[0050] The flexible printed circuit board 1 has a circuit trace 14 and a first surface 11 along its thickness direction. Multiple light-emitting elements 2 are spaced apart on the first surface 11 of the flexible printed circuit board 1 and electrically connected to the circuit trace 14. A flexible display layer 3 is fixedly stacked on the first surface 11 of the flexible printed circuit board 1 and covers each light-emitting element 2. The flexible display layer 3 corresponds to the position of the display window 205. The flexible display layer 3 has multiple light-transmitting areas 31, each light-transmitting area 31 being opposite to at least one light-emitting element 2. The area of ​​the flexible display layer 3 other than the light-transmitting areas 31 is a light-shielding area 32.

[0051] 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) board, is a flexible circuit board with printed circuit traces 14. It has advantages such as good flexibility, light weight, and thinness. In the specific manufacturing process, the desired flexible printed circuit board 1 can be obtained by printing circuit traces 14 on a flexible film. The flexible film can be a high-performance polymer material such as polyimide film or polyester film, which has excellent heat resistance, chemical stability, and bendability.

[0052] In this embodiment, the light-emitting element 2 can be an LED bead or other electrically energized light-emitting component. In some optional implementations, the light-emitting element 2 can be an LED bead with dimensions of 0.5–1.5 mm (length) × 0.2–0.8 mm (width) × 0.1–0.8 mm (thickness). Preferably, the light-emitting element 2 can be a 0402 LED bead, with dimensions of 1.0 mm (length) × 0.5 mm (width) × 0.4 mm (thickness). After repeated testing, when the first display component 60 provided in this embodiment uses this type of LED bead as the light-emitting element 2, compared to LED beads of other sizes, the first display component 60 achieves better display effects and higher reliability. 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 or conductive adhesive), and forms an electrical connection with the circuit trace 14 of the flexible printed circuit board 1.

[0053] In this embodiment, the material of the flexible display layer 3 can be flexible materials such as polyimide (PI), polyethylene terephthalate (PET), polyethylene phthalate (PEN), liquid crystal polymer (LCP), polyvinyl alcohol (PVA), and polydimethylsiloxane (PDMS), as long as it meets the usage requirements. This embodiment does not impose specific limitations on the specific material of the flexible display layer 3. 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 coating with light-shielding ink. For example, when the flexible display layer 3 is a transparent polyimide film, light-shielding ink can be coated on the surface of the polyimide film in a predetermined manner. The area of ​​the polyimide film coated with 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 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-shielding area 32 can be formed on the flexible display layer 3 by means of 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 (at this time, the light-transmitting area 31 is essentially a through hole), and the area in the PET film that is not engraved is formed as the light-shielding area 32.

[0054] It should be noted that, in specific implementation, the shape, size, and positional distribution of each light-transmitting area 31 can be determined according to actual usage requirements. This embodiment does not impose specific limitations 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, the corresponding shape of the light display information can be displayed. For example, when the light emitted by the light-emitting element 2 reaches the letter-shaped light-transmitting area 31, 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, various shapes of light display information can be obtained. The different shapes of light display information can be used to characterize various information of the aerosol generating device (such as remaining power, operating power, remaining amount of aerosol forming material, 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 usage requirements. This embodiment does not impose specific limitations on this either.

[0055] In this embodiment, it should also be noted that, in specific implementation, the flexible display layer 3 can be fixedly laminated onto the first surface 11 of the flexible printed circuit board 1 by means of bonding or other methods. Optionally, such as... Figure 7 As shown, a third adhesive layer 33 is provided on the side surface of the flexible display layer 3 facing the flexible printed circuit board 1. The flexible display layer 3 can be quickly and reliably bonded to the flexible printed circuit board 1 through the third adhesive layer 33 to form an integrated laminated structure. In 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 meets the usage requirements. This embodiment does not impose specific limitations on this.

[0056] In the technical solution provided in this application embodiment, a plurality of light-emitting elements 2 are distributed on the first surface 11 of the flexible printed circuit board 1. A flexible display layer 3 with 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, thereby enabling the plurality of light-emitting elements 2 to be encapsulated between the flexible display layer 3 and the flexible printed circuit board 1. The flexible printed circuit board 1 can serve 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 serve as a medium for the plurality of light-emitting elements 2 to be electrically connected to the power supply. 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 areas 31 of the flexible display layer 3. That is, the light-transmitting areas 31 of the flexible display layer 3 can serve as the light display area of ​​the first display component 60, thereby realizing the display function of the first display component 60.

[0057] Since both the flexible display layer 3 and the flexible printed circuit board 1 are flexible structures, the first display component 60 formed by stacking the flexible display layer 3 and the flexible printed circuit board 1 is also a flexible structure, which can be bent. Thus, based on the bendable characteristic of the first display component 60, the first display component 60 can be wrapped around the outer periphery of the fixed tube, 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.

[0058] Please refer to Figure 8 In some optional embodiments of this application, the first display component 60 further includes a first adhesive layer 15, and the flexible printed circuit board 1 also has a second surface 12 disposed opposite to the first surface 11. The first adhesive layer 15 is disposed on the second surface 12 and bonded to the fixing tube. Thus, in some application scenarios where the first display component 60 of this embodiment is used in an aerosol generating device, the entire first display component 60 can be quickly attached to the outer surface of the fixing tube via the first adhesive layer 15, thereby improving the ease of installation of the first display component 60. In specific implementations, the first adhesive layer 15 can be a type of adhesive such as double-sided tape or structural adhesive, as long as it meets the usage requirements; this embodiment does not impose specific limitations on this.

[0059] Please refer to Figure 6 and Figure 9 In some optional embodiments of this 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 that of 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 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. The current driving element 41 and the current input interface 42 are installed at intervals on the second mounting area 112 and are all electrically connected to the circuit trace 14.

[0060] In this embodiment, by providing a current input interface 42 electrically connected to the circuit trace 14, in some application scenarios where the first display component 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 component 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. This allows for quick and easy electrical connection between each light-emitting element 2 and the controller of the aerosol generating device. The current input interface 42 can be a general-purpose connector or other types of communication interfaces, as long as it meets the usage requirements. This embodiment does not impose specific limitations on this.

[0061] In this embodiment, by setting a driving element electrically connected to the circuit trace 14, in some application scenarios where the first display component 60 of this embodiment is used in an aerosol generating device, when the power supply component of the aerosol generating device is turned on through the current input interface 42, the power supply component can easily drive each light-emitting element 2 to emit light in a preset manner, so as to display the required information on the flexible display layer 3. It should be noted that, in specific implementations, the driving element can be a driving chip commonly used in the art. Since its specific structure and usage principle are well known to those skilled in the art, they will not be described in detail here.

[0062] Please refer to Figure 6 , Figure 9-10 as well as Figure 14 In some optional embodiments of this application, the edge of the flexible printed circuit board 1 is provided with a clearance notch 13, the second mounting area 112 is located within the clearance notch 13, and 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 configuration, compared to the configuration where the second mounting area 112 of the flexible printed circuit board 1 protrudes from the edge of the flexible printed circuit board 1 (e.g., ...), provides a better fit. Figure 11 As shown), in some application scenarios where the first display component 60 of this embodiment is used in an aerosol generating device, it is beneficial to reduce the risk of interference between the first mounting area 111 and the second mounting area 112 during the process of mounting the first display component 60 around the outer surface of the aerosol generating device in the circumferential direction. This facilitates increasing the display area of ​​the first display component 60 in the circumferential direction of the aerosol generating device. For example, assuming the first display component 60 is a flexible strip sheet with a certain length and width, if the second mounting area 112 of the flexible printed circuit board 1 protrudes from one of the width edges of the flexible printed circuit board 1 (e.g., ... Figure 7As shown, during the process of mounting the strip-shaped first display component 60 around the outer surface of the aerosol generating device in a circumferential manner, the second mounting area 112 of the flexible printed circuit board 1 is prone to overlap with another width edge of the flexible printed circuit board 1 and interfere with the end of the first mounting area 111 that is away from the second mounting area 112. This makes 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.

[0063] In the technical solution provided in this embodiment, since the second mounting area 112 of the flexible printed circuit board 1 is designed to avoid interference, that is, the second mounting area 112 of the flexible printed circuit board 1 is located within the avoidance notch 13 opened on the edge of the flexible printed circuit board 1, the first display component 60 can be mounted around the outer surface of the aerosol generating device in the circumferential direction, thus effectively avoiding interference between the end of the first mounting area 111 away from the second mounting area 112 and the second mounting area 112. This allows the first display component 60 to be easily formed into an open ring or a complete closed ring structure, thereby maximizing the display area of ​​the aerosol generating device in the circumferential direction.

[0064] In this embodiment, it should be noted that in some specific application scenarios, when the flexible printed circuit board 1 is a strip with a certain length and width, an avoidance notch 13 for accommodating the second mounting area 112 can be opened on the long edge of the flexible printed circuit board 1. Figure 9-10 As shown, a clearance notch 13 for accommodating the second mounting area 112 can also be provided on the width edge of the flexible printed circuit board 1. This embodiment does not impose specific limitations on this.

[0065] Please refer to Figure 9 In some optional embodiments of this application, a plurality of test points 43 made of metal are also exposed on the second mounting area 112 of the flexible printed circuit board 1. The plurality of test points 43 are electrically connected to the circuit traces 14 of the flexible printed circuit board 1. In this way, by setting a plurality of test points 43 made of metal, it is convenient for testers to perform corresponding functional tests or fault tests on the first display component 60.

[0066] Please continue to refer to Figure 9In some optional embodiments of this application, the first display component 60 further includes a flexible flat cable 52, one end of which is plugged into the current input interface 42. This configuration allows installers to quickly and easily connect the first display component 60 to the power supply component of the aerosol generating device in scenarios where the first display component 60 of this embodiment is used in an aerosol generating device. In practice, only the end of the flexible flat cable 52 furthest from the current input interface 42 needs to be plugged into the communication interface of the power supply component, which is very convenient.

[0067] Please refer to Figure 9-10 In some optional embodiments of this application, the first display component 60 further includes a metal sheet 51, which is fixed to the side of the flexible film facing away from the second mounting area 112. In this embodiment, the metal sheet 51 can reinforce (i.e., supplement the strength) the portion of the flexible printed circuit board 1 containing the second mounting area 112, thereby facilitating the 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 application scenarios where the first display component 60 of this embodiment is mounted on the outer surface of the aerosol generating device. To further facilitate the positioning of 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 also provided on the surface of the metal sheet 51.

[0068] Please refer to Figure 8 In some optional embodiments of this application, the first display component 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 through the flexible reflective layer 6. In this embodiment, the flexible reflective layer 6 improves the lighting display effect of the first display component 60 while ensuring that the first display component 60 can be bent. Specifically, after the light emitted by the light-emitting element 2 shines on the light-transmitting area 31 of the flexible display layer 3, a portion of the light is reflected. The presence of the flexible reflective layer 6 can reflect this reflected light back to the light-transmitting area 31 of the flexible display layer 3 to a certain extent, thereby improving the light utilization rate and enabling the first display component 60 to obtain a better lighting display effect. In specific implementation, the flexible reflective layer 6 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 6), or a reflective ink layer, as long as it meets the usage requirements. This embodiment does not impose specific limitations on this.

[0069] Please continue to refer to Figure 8 , Figure 12 and Figure 13In some optional embodiments of this 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 adhesive 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 uniformly diffuse the light emitted by the light-emitting elements 2, so that the light emitted by the light-emitting elements 2 can be diffused more evenly 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 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 meet the usage requirements. This embodiment does not impose specific limitations on this. Optionally, in some embodiments, the flexible diffusion layer 7 is a yellow fluorescent ink film, 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 side surface of the flexible diffusion layer 7 facing away from the flexible display layer 3, so that the flexible diffusion layer 7 can be bonded to the flexible printed circuit board 1 (or the flexible reflective layer 6, or the flexible light-shielding layer 8 described later). The fourth adhesive layer 71 can be an adhesive layer of the type of double-sided tape, structural adhesive, etc.

[0070] Please continue to refer to Figure 8 and Figure 14 In some optional embodiments of this application, the first display component 60 further includes a flexible light-shielding layer 8. The flexible light-shielding layer 8 has multiple 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 opposite to at least one light-transmitting area 31. In this embodiment, the flexible light-shielding layer 8 reduces the loss of light emitted by the light-emitting element 2, allowing the light emitted by the light-emitting element 2 to be transmitted more fully and concentratedly to the light-transmitting area 31 of the flexible display layer 3, thereby improving the lighting display effect of the first display component 60. In specific implementations, the flexible light-shielding layer 8 can be made of non-transparent flexible materials such as silicone, rubber, or silicone rubber, as long as it meets the usage requirements. This embodiment does not impose specific limitations on this.

[0071] Please continue to refer to Figure 8In some optional embodiments of this 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 easily and quickly laminated onto the first surface 11 of the flexible printed circuit board 1, or it can be easily and quickly laminated onto the flexible reflective layer 6. In specific implementations, the second adhesive layer 82 can be a type of adhesive such as double-sided tape or structural adhesive, as long as it meets the usage requirements; this embodiment does not impose specific limitations on this.

[0072] Based on the bendable nature of the first display component 60, the first display component 60 can be wrapped around multiple outer surfaces of the fixing member 30 simultaneously, 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.

[0073] The aerosol generating device of this utility model also includes a light-transmitting protective cover 92. The light-transmitting protective cover 92 is provided with a snap hook 921 and a docking arm 922. The light-transmitting protective cover 92 covers the display window 205. The snap hook 921 is located on the inner wall surface of the light-transmitting protective cover 92 and is snapped into the wall of the snap hole 2032. The docking arm 922 is inserted into the docking groove 2033. During assembly, the light-transmitting protective cover 92 is first aligned with the display window 205. Then, force is applied to the light-transmitting protective cover 92 in the horizontal direction to move the docking arm 922 toward the docking groove 2033. After the docking arm 922 is fully inserted into the docking groove 2033, the snap hook 921 is snapped into the wall of the snap hole 2032, thereby reliably connecting the light-transmitting protective cover 92 to the outer shell 20.

[0074] Because the docking arm 922 is located inside the housing 20, when the outer wall of the housing 20 is subjected to lateral forces, it is hindered by the docking arm 922, thus preventing deformation, resulting in high structural reliability and improved service life. Furthermore, guided by the docking arm 922, the snap hook 921 and snap hole 2032 are easily aligned, facilitating assembly and improving production efficiency. The light-transmitting protective cover 92 protects the portion of the first display component 60 located in the display window 205 area, preventing the user from touching the first display component 60. Preferably, the light-transmitting protective cover 92 is detachably connected to the housing 20.

[0075] In this embodiment, thanks to the above improvements, the aerosol generating device of this embodiment has the advantage of a large display area, enabling it to display more visual information to the user. It should be noted that, in specific implementations, the first display component 60 can be arranged around the outer shell 209 in a semi-enclosed (in which case the first display component 60 can be arranged in an open ring such as a "U") or fully enclosed (in which case the first display component 60 can be arranged in a closed ring such as an "O") manner. The specific encirclement method of the first display component 60 can be determined according to actual usage requirements, and this embodiment does not impose specific limitations on it.

[0076] Since at least a portion of the first display component 60 and at least a portion of the second display component 70 are located on the same side of the housing, they are used to display graphic and textual information in combination. Therefore, the images displayed by the first display component 60 and the second display component 70 can be combined to form a complete image, even though the resolutions of the first display component 60 and the second display component 70 are different. Thus, their ingenious combination can display rich and specific images, reducing costs and facilitating widespread application.

[0077] In summary, since the housing includes an outer shell 20 and a fastener 30, with the fastener 30 located inside the outer shell 20, and the outer shell 20 having a snap-fit ​​hole 2032, a mating groove 2033, and a display window 205, the mating groove 2033 being located on the inner wall of the outer shell 20 and extending to the window of the display window 205, the light-transmitting protective cover 92 covering the display window 205, the snap-fit ​​hook being located on the inner wall of the light-transmitting protective cover and being snapped into the wall of the snap-fit ​​hole, and the mating arm extending at least partially into the mating groove, it can prevent the outer shell from deforming inward. It has the advantages of being easy to assemble, not easily deformed, and having good reliability.

[0078] It should be noted that other aspects of the aerosol generating apparatus disclosed in this application can be found in the prior art, and will not be repeated here.

[0079] The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
