Description

Technical Field

[0002] An aerosol generating device is an electronic device that can atomize aerosol-forming substances such as tobacco oil and liquid medicine stored in it into an aerosol through electrical heating. Currently, aerosol generating devices on the market generally include structures such as an atomizer core, a battery, and a storage chamber. The storage chamber generally contains aerosol-forming substances, and 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 battery provides electrical energy to the atomizer core, allowing the atomizer core to be powered and heated. The heat generated by the power supply to the atomizer 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. In order to facilitate the user to know the remaining power of the aerosol generating device at any time and intuitively, the outside of the aerosol generating device is usually equipped with an LCD screen that can display information such as the remaining power.

[0046] Please refer to Figures 1-10 as well as Figures 13-17 An embodiment of the present application provides an aerosol generating system, which includes a power supply device 1 and an aerosol generating device 2. The power supply device 1 is used to be detachably connected to the aerosol generating device 2 to power the aerosol generating device 2. Specifically, the power supply device 1 includes a first housing 11, a first battery 12 installed in the first housing 11, a first control circuit board 13 installed in the first housing 11, a first display component 14 for displaying first visual information, a first electrode assembly 15 for electrically connecting to the aerosol generating device 2, and a first connector 16 for detachably connecting to the aerosol generating device 2, wherein:

[0047] The first shell 11 has multiple outer surfaces 110 with different orientations along its circumference. In a specific implementation, the first shell 11 can be an integrated structure or a split structure assembled from different shell structures. Its specific structural form can be determined according to actual usage needs, and this embodiment does not impose any specific restrictions on this.

[0048] The first control circuit board 13 is electrically connected to the first battery 12, and the first display component 14 is a flexible display component. The first control circuit board 13 can be used to control the working state of the flexible display component (for example, controlling the flexible display component to connect to the first battery 12 and display the first visual information, or controlling the flexible display component to disconnect the electrical connection with the first battery 12 and stop displaying the first visual information), control the working state of the first battery 12 (for example, controlling the output power of the first battery 12), monitor the working condition of the first battery 12 (for example, monitoring the remaining power of the first battery 12), etc., wherein the structural form of the first control circuit board 13 can be a single-chip microcomputer, a processor, a controller, or other mature devices with control functions in this field.

[0049] The flexible display assembly is electrically connected to the first control circuit board 13. The flexible display assembly is mounted on the first shell 11 along the circumference of the first shell 11 and covers at least two outer surfaces 110 of the first shell 11. In some optional embodiments, the structure of the flexible display assembly can be a flexible touch screen of the type of flexible OLED (organic light-emitting diode) touch screen, flexible AMOLED (active matrix organic light-emitting diode) touch screen, etc. Moreover, the flexible display assembly can be fixed to the multiple outer surfaces 110 of the first shell 11 along its own circumference by gluing, snapping, etc. It can be understood here that after the flexible display assembly is mounted on the first shell 11 along the circumference of the first shell 11, the light-emitting surface of the flexible display assembly is arranged to face away from the first shell 11 so that the user can observe the light information displayed by the flexible display assembly.

[0050] The first electrode assembly 15 is provided on the surface of the first shell 11 that is not covered with the flexible display assembly, and the first electrode assembly 15 is electrically connected to the first control circuit board 13. It can be understood here that when the power supply device 1 is used in combination with the aerosol generating device 2, the power supply device 1 can form an electrical connection with the aerosol generating device 2 through the first electrode assembly 15, thereby supplying power to the aerosol generating device 2. In some optional embodiments, the structure of the first electrode assembly 15 can be a non-retractable fixed electrode, in which case the first electrode assembly 15 includes at least two conductive nails spaced apart on the surface of the first shell 11; in other optional embodiments, the structure of the first electrode assembly 15 can also be an elastic electrode with elastic retractable function, in which case the first electrode assembly 15 includes at least two conductive elastic pins (such as) spaced apart on the surface of the first shell 11. Figure 5 It should be noted that the specific structural form of the conductive elastic needle is well known to those skilled in the art and will not be described in detail here.

[0051] The first connecting member 16 is provided on the surface of the first shell 11 that is not covered with the flexible display component, and the first connecting member 16 and the first electrode assembly 15 are provided on the same side of the first shell 11. It can be understood here that when the power supply device 1 and the aerosol generating device 2 are used in combination, the power supply device 1 can form a detachable connection with the aerosol generating device 2 through the first connecting member 16, wherein the detachable connection between the power supply device 1 and the aerosol generating device 2 can be a plug-in connection, a snap connection, a magnetic connection, etc., wherein, as Figures 4-5 As shown, when the detachable connection between the power supply device 1 and the aerosol generating device 2 is a magnetic connection, the first connecting member 16 includes at least one first magnetic member 161. Accordingly, the aerosol generating device 2 is provided with at least one second magnetic member 271 attracted to the first magnetic member 161. At least one of the first magnetic member 161 and the second magnetic member 271 is a magnet. For example, both the first magnetic member 161 and the second magnetic member 271 are magnets. For another example, one of the first magnetic member 161 and the second magnetic member 271 is a magnet, and the other is a magnetic body made of a magnetic conductive material (for example, a magnetic conductive material such as iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as the use requirements can be met, this embodiment does not impose specific restrictions on the structural form of the first magnetic member 161 and the second magnetic member 271.

[0052] In the technical solution of this embodiment, a bendable flexible display component is adopted to display visual information, and the bendable characteristics of the flexible display component are utilized to cover the flexible display component on multiple outer surfaces 110 of the first shell 11 in different directions along the circumference of the first shell 11 of the power supply device 1, so that the display area of ​​the flexible display component can be distributed on multiple outer surfaces 110 in different directions along the circumference of the first shell 11, thereby improving the information display range of the power supply device 1, so that the power supply device 1 can realize multi-directional information display, that is, compared with the traditional power supply device with only one outer surface covered with a display screen, the power supply device 1 provided in this embodiment has a larger information display range and can display more first visual information to the user. For example, the flexible display component displays the remaining power of the first battery 12, the output power of the first battery 12, the operating temperature of the first battery 12, preset pattern information and other first visual information to the user.

[0053] In addition, in the power supply device 1 provided in this embodiment, since the first electrode assembly 15 for electrically connecting to the aerosol generating device 2 and the first connector 16 for detachably connecting to the aerosol generating device 2 are both arranged on the same surface of the first shell 11 that is not covered with the flexible display component, it is possible to ensure that the power supply device 1 provided in this embodiment can be detachably assembled with the aerosol generating device 2 into a whole for use, while ensuring that the display area of ​​the flexible display component will not be blocked by the aerosol generating device 2, thereby ensuring that the aerosol generating system formed by the power supply device 1 and the aerosol generating device 2 has a larger information display range, so as to display more visual information to the user in multiple directions.

[0054] Alternatively, see Figures 5-7 In some optional embodiments of the present application, the first shell 11 has a first end face 111 and a second end face 112 opposite to each other along its own height direction, and the first shell 11 has four outer surfaces 110 located between the first end face 111 and the second end face 112 along its own circumference, wherein two outer surfaces 110 are arranged back to back with each other along the first direction of the first shell 11, and the other two outer surfaces 110 are arranged back to back with each other along the second direction of the first shell 11. Among the four outer surfaces 110 of the first shell 11, the flexible display component covers three of the outer surfaces 110, and the first electrode assembly 15 and the first connecting member 16 are both arranged on the remaining outer surface 110, wherein the first direction of the first shell 11, the second direction of the first shell 11, and the height direction of the first shell 11 are perpendicular to each other. As shown schematically, Figures 5-6 As shown, the four outer surfaces 110 of the first shell 11 distributed along its circumference are respectively the front side surface, the rear side surface, the left side surface and the right side surface of the first shell 11. The first direction of the first shell 11 is Figures 5-6The front-to-back direction in the first housing 11 is Figures 5-6 The left and right directions in the figure are as follows: Figures 5-6 In the vertical direction, the flexible display assembly covers the front, rear, and right surfaces of the first housing 11, and the first electrode assembly 15 and the first connector 16 are both provided on the left surface of the first housing 11. It should be noted that the outer surfaces 110 of the first housing 11 along its circumference can be either flat or curved, depending on actual usage requirements, and this embodiment does not impose any specific limitations on this.

[0055] In this embodiment, based on the above-mentioned structural design, since the outer surfaces 110 of the first shell 11 in three different directions along its own circumference are all covered by the flexible display component, and the first electrode assembly 15 and the first connecting member 16 are both arranged on the outer surface of the same side of the first shell 11 that is not covered by the flexible display component, the power supply device 1 can realize information display in three different directions regardless of whether it is in a state of being combined with the aerosol generating device 2 or in a state of not being combined with the aerosol generating device 2. That is, the user can observe the lighting information displayed by the flexible display component from three different directions of the power supply device 1, thereby improving the information display range of the power supply device 1, so that the power supply device 1 can display more visual information to the user in multiple directions.

[0056] Optionally, in some other optional embodiments of the present application, the information display of the power supply device 1 in four different directions can be achieved in the following manner, specifically:

[0057] like Figure 13 as well as Figures 16-17As shown, the first shell 11 has a first end face 111 and a second end face 112 opposite to each other along its height direction (illustratively, the first end face 111 of the first shell 11 is the upper end face of the first shell 11, and the second end face 112 of the first shell 11 is the lower end face of the first shell 11). The first shell 11 has four outer surfaces 110 located between the first end face 111 and the second end face 112 along its circumference, wherein two outer surfaces 110 are arranged back to back with each other along the first direction of the first shell 11, and the other two outer surfaces 110 are arranged back to back with each other along the second direction of the first shell 11. The flexible display component covers the four outer surfaces 110 of the first shell 11. The first end surface 111 is recessed with a receiving cavity 1110 capable of receiving at least part of the aerosol generating device 2. The receiving cavity 1110 has a cavity wall 11101 facing the cavity opening of the receiving cavity 1110 (the cavity wall 11101 can be regarded as one of the inner surfaces of the first shell 11). The first electrode assembly 15 and the first connecting member 16 are both arranged on the cavity wall 11101, wherein the first direction of the first shell 11, the second direction of the first shell 11, and the height direction of the first shell 11 are perpendicular to each other. As shown schematically, Figures 13-14 as well as Figures 17-18 As shown, the four outer surfaces 110 distributed along the circumference of the first shell 11 are respectively the front surface, rear surface, left surface and right surface of the first shell 11, and the flexible display component covers the front surface, rear surface, left surface and right surface of the first shell 11 at the same time.

[0058] In this embodiment, based on the above-mentioned structural design, since the outer surfaces 110 of the first shell 11 in four different directions of front, back, left and right are all covered by the flexible display component, and the first electrode assembly 15 and the first connecting member 16 are both arranged on the same surface of the first shell 11 that is not covered with the flexible display component, the power supply device 1 can display information to the user in four different directions of front, back, left and right, regardless of whether it is in a state of being combined with the aerosol generating device 2 or in a state of not being combined with the aerosol generating device 2, thereby improving the information display range of the power supply device 1, so that the power supply device 1 can display more first visual information to the user in an all-round manner of 360° along its own circumference. Moreover, when the power supply device 1 is in a state of being combined with the aerosol generating device 2, the aerosol generating device 2 is at least partially located in the receiving cavity 1110 of the first shell 11 and forms a detachable connection with the first connecting member 16 located in the receiving cavity 1110. That is, when the power supply device 1 is in a state of being combined with the aerosol generating device 2, the aerosol generating device 2 will be constrained by the receiving cavity 1110 and the first connecting member 16 at the same time, thereby making it more difficult for the aerosol generating device 2 to separate from the power supply device 1. In this embodiment, it should be noted that the power supply device 1 provided in this embodiment (such asFigures 16-18 As shown) and Figures 2-3 The main difference between the power supply device 1 provided in the embodiments shown in 5-7 is that the setting positions of the first electrode assembly 15 and the first connecting member 16, and the number of outer surfaces 110 covered by the flexible display assembly are different. The internal structures of the two are similar, which can be understood by those skilled in the art and will not be repeated here.

[0059] For further information, please refer to Figures 6-7 In some optional embodiments of the present application, the power supply device 1 further includes a charging interface 17 provided on the second end surface 112 of the first shell 11, and the charging interface 17 is electrically connected to the first control circuit board 13. In a specific implementation, the structural form of the charging interface 17 can be a USB interface or a Type-C interface, and this embodiment does not impose specific restrictions on this. With such a configuration, when the power of the first battery 12 in the power supply device 1 is low or exhausted, the first battery 12 can be charged in a wired manner so that the power supply device 1 can be reused. In this embodiment, it should be noted that in some specific application scenarios, when the power supply device 1 is in a charging state, the first visual information such as the current remaining power of the power supply device 1, the current charging speed of the power supply device 1, and a preset charging animation can be displayed to the user through a flexible display component.

[0060] For further information, please refer to Figures 6-8 as well as Figures 18-19 In some optional embodiments of the present application, along the height direction of the first shell 11, the flexible display component has a relative first edge 1401 and a second edge 1402, wherein, assuming that the minimum vertical height between the first edge 1401 and the second edge 1402 is H1, the maximum vertical height between the first edge 1401 and the second edge 1402 is H2, and the vertical height between the first end surface 111 of the first shell 11 and the second end surface 112 of the first shell 11 is H3, then 0.5H3≤H1≤0.9H3, 0.5H3≤H2≤0.9H3. For example, assuming that H3 is 70mm, H1 can be 35mm, 42mm, 49mm, 56mm, 63mm, etc., and H2 can be 35mm, 42mm, 49mm, 56mm, 63mm, etc. In this embodiment, it can be understood that when the flexible display component is in a non-enclosed expanded state, if the display area of ​​the flexible display component is a rectangle (such as Figure 8 As shown), H1=H2; and when the flexible display component is in a non-enclosed expanded state, if the display area of ​​the flexible display component is an irregular shape (such as Figure 19 As shown), then H1

[0061] ​In this embodiment, based on the above structural design, on the one hand, by setting the minimum vertical height between the first edge 1401 and the second edge 1402 of the flexible display component to 0.5 to 0.9 times the vertical height between the first end surface 111 and the second end surface 112 of the first shell 11, it is possible to ensure that the power supply device 1 can have a larger display area along its own height direction for displaying information; on the other hand, by setting the maximum vertical height between the first edge 1401 and the second edge 1402 of the flexible display component to 0.5 to 0.9 times the vertical height between the first end surface 111 and the second end surface 112 of the first shell 11, it is possible to reduce the risk that when the flexible display component is covered on multiple outer surfaces 110 of the first shell 11, part of the edge of the flexible display component along its width direction cannot cover the outer surface 110 of the first shell 11 due to uneven installation of the flexible display component, thereby generating a sense of abruptness, thereby affecting the overall aesthetic appearance of the power supply device 1.

[0062] For further information, please refer to Figures 16-17 In some optional embodiments of the present application, the flexible display component is a flexible OLED touch screen or a flexible AMOLED touch screen. The outer surface of the first shell 11 is provided with a mounting groove 113 extending along the circumference of the shell. The groove wall of the mounting groove 113 includes at least two outer surfaces 110. The flexible display component is adapted to be installed in the mounting groove 113 and covers at least two outer surfaces 110. It can be understood here that the shape and size of the flexible display component are adapted to the shape and size of the mounting groove 113, so that the flexible display component can be adapted to be installed in the mounting groove 113 of the first shell 11.

[0063] In this embodiment, the installation groove 113 can, on the one hand, play a certain positioning role in the installation of the flexible display assembly, thereby facilitating the installation of the flexible display assembly. On the other hand, it can properly accommodate the flexible display assembly, preventing the light-emitting surface of the flexible display assembly from excessively protruding from the outer surface of the first housing 11 and affecting the overall aesthetic appearance of the power supply device 1. In this embodiment, it should be noted that the specific structure and working principle of the flexible OLED touch screen or flexible AMOLED touch screen are well known to those skilled in the art and will not be described in detail here.

[0064] In some other optional embodiments of the present application, the flexible display assembly 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 may be of the following structural forms:

[0065] For details, please refer to Figures 6-10The flexible display assembly includes a display film 146 made of a flexible material and a flexible printed circuit board 141 having a circuit track 1410. A plurality of light-emitting elements 142 electrically connected to the circuit track 1410 are fixed on one side surface of the flexible printed circuit board 141 along its own thickness direction. The side surface of the flexible printed circuit board 141 facing away from the plurality of light-emitting elements 142 can be connected to the first shell 11 by gluing (the glue can be double-sided tape) and covers at least two outer surfaces 110 of the first shell 11. The flexible printed circuit board 141 is provided with a plurality of light-emitting elements 142. The circuit traces 1410 of the circuit board 141 are electrically connected to the first control circuit board 13. The display film 146 can be fixedly connected to one side of the flexible printed circuit board 141 where multiple light-emitting elements 142 are provided by gluing (the glue can be double-sided tape, structural glue, optically transparent glue, etc.) and covers each light-emitting element 142. The display film 146 has multiple light-transmitting areas 1461 for allowing light emitted by the light-emitting elements 142 to pass through. The area of ​​the display film 146 other than the light-transmitting area 1461 is a light-shielding area 1462.

[0066] In this embodiment, it is understood that the flexible printed circuit board 141, also known as an FPC (Flexible Printed Circuit) board, is a flexible circuit board with printed circuit traces 1410. It has advantages such as good flexibility, light weight, and thinness. In a specific manufacturing process, the desired flexible printed circuit board 141 can be obtained by printing the circuit traces 1410 on a polyimide film or a polyester film. It is also understood that the flexible printed circuit board 141 can serve as a mounting carrier for the multiple light-emitting elements 142, and the circuit traces 1410 on the flexible printed circuit board 141 can serve as a medium for electrically connecting the multiple light-emitting elements 142 to the first control circuit board 13.

[0067] In this embodiment, it should be noted that, in a specific implementation, the light-emitting element 142 may be a component that emits light when energized, such as an LED lamp bead. Furthermore, the light-emitting element 142 may be fixed to the surface of the flexible printed circuit board 141 by welding or bonding (e.g., bonding with insulating glue or conductive glue), and may be electrically connected to the circuit traces 1410 of the flexible printed circuit board 141.

[0068] It should be further noted that in the embodiments, the material of the display diaphragm 146 can be 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, and the embodiments do not specifically limit the specific material of the display diaphragm 146. In some optional embodiments, when the display diaphragm 146 is made of transparent flexible material, the light transmission area 1461 and the light shielding area 1462 can be formed on the display diaphragm 146 by coating light shielding ink or the like, for example, when the display diaphragm 146 is a transparent polyimide film, light shielding ink can be coated on the surface of the polyimide film in a predetermined manner, and the area of the polyimide film coated with light shielding ink can be regarded as the light shielding area 1462 of the display diaphragm 146, and the area of the polyimide film not coated with light shielding ink can be regarded as the light transmission area 1461 of the display diaphragm 146.

[0069] In some optional embodiments, when the display diaphragm 146 is made of opaque flexible material, the light transmission area 1461 and the light shielding area 1462 can be formed on the display diaphragm 146 by laser engraving or the like, for example, when the display diaphragm 146 is an opaque PET film, the required light transmission area 1461 (the light transmission area 1461 at this time is essentially a through hole) can be engraved on the surface of the PET film by laser engraving, and the area of the PET film not engraved forms the light shielding area 1462. Of course, the display diaphragm 146 can also be other diaphragm structures with light transmission area 1461 and light shielding area 1462 that are mature in the art, for example, in some optional embodiments, the display diaphragm 146 can also be a PET color film with light transmission area 1461 and light shielding area 1462 that are mature in the art, as long as it can meet the use requirements, and the embodiments do not specifically limit this.

[0070] In addition, in a specific implementation, the number of light-transmitting areas 1461 on the display film 146 and the shape and size of each light-transmitting area 1461 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 1461 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 142 reaches the corresponding light-transmitting area 1461, light display information of the corresponding shape can be displayed. For example, when the light emitted by the light-emitting element 142 reaches the letter-shaped light-transmitting area 1461, the user can observe the glowing letters on the surface of the display film 146. In this way, by combining multiple light-transmitting areas 1461 of different shapes, light display information of multiple different shapes can be obtained, and thus by combining light display information of different shapes, various information of the power supply device 1 can be represented, such as the remaining power of the first battery 12, the output power of the first battery 12, the operating temperature of the first battery 12, preset pattern information, etc. In addition, the number of light-emitting elements 142 corresponding to each light-transmitting area 1461 can be one or more, which can be determined according to actual usage requirements and is not specifically limited in this embodiment.

[0071] In this embodiment, based on the above-described structural design, the first control circuit board 13 can control the plurality of light-emitting elements 142 to illuminate when powered on or to stop emitting light when powered off. The light emitted by the plurality of light-emitting elements 142 when powered on can be displayed in the light-transmitting area 1461 of the display film 146. That is, the light-transmitting area 1461 of the display film 146 can serve as the light display area of ​​the flexible display assembly, thereby realizing the display function of the flexible display assembly. In addition, since the display film 146 and the flexible printed circuit board 141 are both flexible structures, the display assembly formed by laminating the display film 146 and the flexible printed circuit board 141 is also a flexible structure, thereby making the flexible display assembly have bendable properties. Moreover, compared to flexible OLED touch screens, flexible AMOLED touch screens, or LED flat-panel displays, the flexible display assembly provided in this embodiment has the advantages of simple structure and low cost.

[0072] For further information, please refer to Figures 5-7In some optional embodiments of the present application, the power supply device 1 also includes a protective shell 18 made of a translucent material (such as glass, acrylic, or other translucent materials). The outer surface of the first shell 11 is provided with a mounting groove 113 extending along the circumference of the first shell 11. The groove wall of the mounting groove 113 includes at least two outer surfaces 110. The flexible display component is fixed in the mounting groove 113 and covers at least two outer surfaces 110. The protective shell 18 is installed on the first shell 11 and covers the flexible display component. There is a gap L between the inner surface of the protective shell 18 and the display film 146. Optionally, the size of the gap L can be 0.1 mm to 2 mm.

[0073] In this embodiment, the provision of the light-transmissive protective case 18 ensures that the user can view the lighting information displayed by the flexible display assembly through the protective case 18 while also protecting the flexible display assembly, thereby reducing the risk of damage to the light-emitting element 142 due to impact from external objects. Furthermore, due to the presence of a gap L between the inner surface of the protective case 18 and the display film 146, this gap L serves as a heat dissipation space for the flexible display assembly, thereby improving the heat dissipation efficiency of the flexible display assembly during operation. Furthermore, it prevents the inner surface of the protective case 18 from squeezing the flexible display assembly and damaging the light-emitting element 142 therein.

[0074] For further information, please refer to Figure 11 In some optional embodiments of the present application, the flexible display assembly further includes a flexible diffusion membrane 145 sandwiched between the flexible printed circuit board 141 and the display film 146 , and the flexible diffusion membrane 145 covers each light-transmitting area 1461 of the display film 146 .

[0075] In this embodiment, the provision of the flexible diffuser film 145 ensures that the flexible display assembly is bendable while uniformly diffusing the light emitted by the light-emitting element 142. This allows the light emitted by the light-emitting element 142 to be more evenly diffused onto the light-transmitting area 1461 of the display film 146, thereby improving the uniformity of the light display of the flexible display assembly. In a specific implementation, the flexible diffuser film 145 can be a transparent flexible film coated with fluorescent ink (for example, fluorescent ink can be coated on a transparent PET film), or other flexible films with light diffusing properties, as long as they meet the requirements of use. This embodiment does not impose specific limitations on this. Alternatively, in some embodiments, the flexible diffuser film 145 can be a yellow fluorescent ink film. In this embodiment, it should be noted that, in a specific implementation, the flexible diffuser film 145 and the display film 146, as well as the flexible diffuser film 145 and the flexible printed circuit board 141, can be laminated together using glue.

[0076] For further information, please refer to Figure 11 In some optional embodiments of the present application, the flexible display assembly further includes a flexible light-shielding sheet 144 sandwiched between the flexible printed circuit board 141 and the display film 146. The flexible light-shielding sheet 144 is provided with a plurality of light-transmitting holes 1441. Each light-transmitting hole 1441 is provided with at least one light-emitting element 142. Each light-transmitting area 1461 is arranged opposite to at least one light-transmitting hole 1441. It should be noted that, in a specific implementation, the number of light-transmitting holes 1441 on the flexible light-shielding sheet 144 and the number of light-transmitting areas 1461 on the display film 146 can be the same or different, as long as the use requirements are met. This embodiment does not impose any specific restrictions on this. In addition, the shape and size of the light-transmitting holes 1441 on the flexible light-shielding sheet 144 and the corresponding light-transmitting areas 1461 on the display film 146 can be the same or different, as long as the use requirements are met. This embodiment also does not impose any specific restrictions on this.

[0077] In this embodiment, the provision of the flexible light shielding sheet 144 can reduce the risk of light leakage in the flexible display assembly while ensuring that the flexible display assembly can still be bent, so that the light emitted by the light-emitting element 142 can be more fully and concentratedly transmitted to the light-transmitting area 1461 of the display film 146, thereby facilitating an improvement in the lighting effect of the flexible display assembly. Specifically, in a specific implementation, the flexible light shielding sheet 144 can be made of a flexible material such as non-transparent silicone, rubber, silicone rubber, sponge, etc., as long as it can meet the requirements of use. 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 144 and the display film 146, as well as the flexible light shielding sheet 144 and the flexible printed circuit board 141, can be laminated together by gluing.

[0078] For further information, please refer to Figure 11 In some optional embodiments of the present application, the flexible display assembly further includes a flexible reflective layer 143 sandwiched between the display film 146 and the flexible printed circuit board 141 , and each light-emitting element 142 is exposed from the flexible reflective layer 143 .

[0079] In the embodiment, the flexible reflective layer 143 can improve the light display effect of the flexible display assembly while ensuring that the flexible display assembly can still be bent. Specifically, in some use scenarios, part of the light emitted by the light emitting element 142 will be reflected after irradiating the light-transmitting area 1461 of the display film 146 (or the flexible diffusion film 145), and the presence of the flexible reflective layer 143 can reflect the part of the reflected light back to the light-transmitting area 1461 of the display film 146 to some extent, thereby improving the utilization rate of the light and enabling the flexible display assembly to obtain better light display effect. In specific implementation, the flexible reflective layer 143 can be a flexible reflective film (such as a transparent polyimide film), can be a paint layer (optionally, to achieve better reflective effect, a white paint layer can be used as the flexible reflective layer 143), or can be a reflective ink layer, as long as the use requirement can be met, and the embodiment does not make a specific limitation thereon. In the embodiment, it should be noted that in some embodiments, the flexible reflective layer 143 and the display film 146 can be laminated together by means of glue adhesion.

[0080] It should be noted that in the structure design of the flexible display assembly including the display film 146, the flexible diffusion film 145, the flexible light shielding sheet 144, and the flexible reflective layer 143 can be simultaneously present, or one or two of them can be selected and arranged, according to the actual use requirement, and the embodiment does not make a specific limitation thereon. Preferably, to obtain better light display effect, as shown in FIG. 1, the display film 146, the flexible diffusion film 145, the flexible light shielding sheet 144, the flexible reflective layer 143, and the flexible printed circuit board 141 are sequentially laminated, and the adjacent two layers of structures can be laminated together by means of glue adhesion. Figure 11

[0081] Further, please refer to Figures 8-10 In some optional embodiments of the present application, one side surface of the flexible printed circuit board 141 provided with the plurality of light emitting elements 142 has a first mounting area 1411 and a second mounting area 1412 which are in connection with each other, the area of the first mounting area 1411 is greater than the area of the second mounting area 1412, the second mounting area 1412 is exposedly arranged at the edge position of the flexible display assembly (for example, assuming that the flexible display assembly is a strip-shaped sheet material with a certain length and width, the second mounting area 1412 is arranged at the length edge or the width edge of the flexible display assembly), the plurality of light emitting elements 142 are fixed in the first mounting area 1411, and the second mounting area 1412 is provided with at least one of a current input interface 147, a current driving element 148, and a plurality of metal test points 149 which are electrically connected with the circuit track 1410.

[0082] ​In this embodiment, the provision of the current input interface 147 facilitates the electrical connection between the circuit trace 1410 of the flexible printed circuit board 141 and the first control circuit board 13. For example, in some specific application scenarios, one end of a flexible flat cable can be connected to the current input interface 147, and the other end of the flexible flat cable can be connected to the current output interface (not shown) of the first control circuit board 13. This allows for quick electrical connection between the circuit trace 1410 of the flexible printed circuit board 141 and the first control circuit board 13, making operation very convenient. The current input interface 147 can be a socket-type connector or other type of communication interface, as long as it meets the requirements of use. This embodiment does not impose specific limitations on this. Accordingly, the structure of the current output interface of the first control circuit board 13 can be the same as the structure of the current input interface 147 of the flexible printed circuit board 141.

[0083] In this embodiment, the provision of the current driving element 148 enables the first control circuit board 13 to control the individual light-emitting elements 142 in the flexible display assembly to emit light in a predetermined manner after the first battery 12 is connected via the current input interface 147, thereby displaying the desired information on the display film 146. It should be noted that, in a specific implementation, the current driving element 148 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.

[0084] In this embodiment, the provision of multiple metal test points 149 can facilitate testers to perform corresponding functional tests or fault tests on the flexible display component.

[0085] Furthermore, considering that in actual practice, when a single long display film 146 is used to simultaneously cover the light-emitting elements 142 in each first installation area 1411, it is easy to cause some of the light-emitting elements 142 to be damaged during the process of installing the display component on the multiple outer surfaces 110 of the first shell 11. The reason is that in the process of wrapping the display component of this embodiment around the multiple outer surfaces 110 of the first shell 11 along the circumference of the first shell 11, it is difficult to avoid bending the display component multiple times. If the display component needs to be reinstalled due to improper installation, the display component needs to be bent more times, and each time When the display assembly is bent once, the entire display film 146 will be stretched to varying degrees and local stress concentration will occur. The greater the degree of bending of the display assembly, the greater the degree of stretching of the display film 146 and the more obvious the local stress concentration. Each time the display film 146 is stretched, the light-emitting element 142 will be squeezed to varying degrees. The part of the display film 146 where the local stress concentration occurs will squeeze the light-emitting element 142 the most. Therefore, when the display assembly is repeatedly bent, especially when the degree of bending is large, it will easily cause some of the light-emitting elements 142 to be crushed by the display film 146.

[0086] Based on the above findings, in order to solve the technical problem that when a single long display film 146 is used to simultaneously cover the light-emitting elements 142 in each first mounting area 1411, some of the light-emitting elements 142 are easily damaged during the process of mounting the display assembly on multiple outer surfaces 110 of the first housing 11, multiple short flexible display films 1460 can be used to replace the single long display film 146. Specifically, please refer to Figure 6 、 Figures 8-10 as well as Figure 12 In some optional embodiments of the present application, at least two first mounting areas 1411 are provided on one side surface of the flexible printed circuit board 141 along its thickness direction. The at least two first mounting areas 1411 are spaced apart along the length direction of the flexible printed circuit board 141, and a plurality of light-emitting elements 142 are fixed in each first mounting area 1411. The display film 146 includes at least two flexible display films 1460 spaced apart, each flexible display film 1460 covering one first mounting area 1411, and each flexible display film 1460 having a plurality of light-transmitting areas 1461. Among the at least two outer surfaces 110 covered by the flexible printed circuit board 141, each outer surface 110 corresponds to at least one flexible display film 1460.

[0087] In the technical solution of this embodiment, each first mounting area 1411 is individually covered with a relatively short flexible display film 1460, and each flexible display film 1460 is provided separately rather than being interconnected into a single, integrated film structure. Therefore, the bending and stretching of each flexible display film 1460 are independent of each other and do not affect each other. For example, after the first flexible display film 1460 is covered on the first outer surface 110 of the first housing 11 (such as the front surface of the first housing 11), when the second flexible display film 1460 is covered on the second outer surface 110 (such as the right side surface of the first housing 11) by bending the display assembly once, the first flexible display film 1460 is not stretched by the bending of the display assembly. As a result, the first flexible display film 1460 does not squeeze the light-emitting elements 142 opposite to it during this process. This effectively reduces the risk of some light-emitting elements 142 being crushed by the flexible display film 1460 during the installation of the display assembly on multiple outer surfaces 110 of the first housing 11.

[0088] In this embodiment, it should be noted that, in some specific application scenarios, in order to improve the production efficiency of the flexible display component, multiple pieces of shorter flexible display films 1460 can be obtained by cutting a single piece of longer display film 146. For example, a single piece of longer display film 146 can be used to simultaneously cover the light-emitting elements 142 in each first installation area 1411, and before the display component is installed on the multiple outer surfaces 110 of the first shell 11, the portion of the single piece of longer display film 146 that does not cover the first installation area 1411 can be cut, so that multiple pieces of shorter flexible display films 1460 can be obtained with intervals in the length direction of the display component.

[0089] Please refer to Figures 1-5 as well as Figures 13-15 The aerosol generating device 2 of the embodiment of the present application includes a second housing 21, an atomizing core 22, a mouthpiece 23, a second electrode assembly 26, a second connector 27, a second battery 24 installed in the second housing 21, a second control circuit board 25 installed in the second housing 21, and a second display assembly 29, wherein:

[0090] The second shell 21 has a connecting surface 211 for connecting to the first shell 11. The interior of the second shell 21 is provided with an airway 212 and a storage cavity 213 for storing aerosol-forming substances. The aerosol-forming substances can be substances such as tobacco oil and liquid medicine, which can be determined according to the actual usage needs of the user; wherein, in a specific implementation, the second shell 21 can be an integrated structure or a split structure assembled by different shell structures. Its specific structural form can be determined according to actual usage needs, and this embodiment does not impose specific restrictions on this.

[0091] The atomizer core 22 is installed in the airflow flow path of the airway 212 so that the aerosol generated by the atomizer core 22 can be carried away by the airflow formed in the airway 212 and discharged to the outside for inhalation by the user. Moreover, the atomizer core 22 is connected to the storage chamber 213 so that the atomizer core 22 can absorb aerosol-forming substances from the storage chamber 213 for heating and atomization. It should be noted here that the specific structural composition and working principle of the atomizer core 22 and the communication method between the atomizer core 22 and the storage chamber 213 are well known to those skilled in the art and will not be repeated here.

[0092] The suction nozzle 23 is arranged on one end surface of the second shell 21 along its own height direction, and the suction nozzle 23 is connected to the air outlet end of the air channel 212. When the user bites the suction nozzle 23 to inhale, the outside air can enter the air channel 212 from the air inlet end of the air channel 212 and form an inhalation airflow. When the inhalation airflow flows through the atomization core 22, it takes away the aerosol generated by the atomization core 22. The aerosol finally flows out of the suction nozzle 23 to the user's mouth along with the inhalation airflow and is inhaled by the user.

[0093] The second control circuit board 25 is electrically connected to the second battery 24 and the atomizer core 22 respectively. The second control circuit board 25 is mainly used to control the working state of the atomizer core 22, for example, to control the atomizer core 22 to connect to the second battery 24 and work according to a predetermined power, or to control the atomizer core 22 to power off and stop working. The structure of the second control circuit board 25 can be a single-chip microcomputer, a processor, a controller, or other mature devices with control functions in the field.

[0094] The second electrode assembly 26 is provided on the connection surface 211 of the second shell 21. The second electrode assembly 26 is electrically connected to the second control circuit board 25, and the second electrode assembly 26 is electrically contacted with the first electrode assembly 15 of the power supply device 1, thereby achieving electrical connection between the aerosol generating device 2 and the power supply device 1, so that the first battery 12 in the power supply device 1 can charge the second battery 24 in the aerosol generating device 2. In a specific implementation, the battery capacity of the first battery 12 can be set to be greater than or equal to the battery capacity of the second battery 24. In addition, in order to achieve reliable electrical contact between the first electrode assembly 15 and the second electrode assembly 26, one of the first electrode assembly 15 and the second electrode assembly 26 is a conductive nail and the other is a conductive elastic needle. For example, Figures 4-5 as well as Figures 14-15 As shown, the first electrode assembly 15 is in the form of a conductive spring pin, and the second electrode assembly 26 is in the form of a conductive nail.

[0095] The second connector 27 is provided on the connection surface 211 of the second shell 21, and the second connector 27 is detachably connected to the first connector 16. In a specific implementation, the detachable connection between the first connector 16 and the second connector 27 can be a snap connection, a plug-in connection, a magnetic connection, etc., as long as it can meet the use requirements, and this embodiment does not impose specific restrictions on this. It can be understood that in some optional embodiments, when the detachable connection between the first connector 16 and the second connector 27 is a snap connection, the structure of the first connector 16 can be a snap, and accordingly, the structure of the second connector 27 is a slot that can be engaged with the snap; in other optional embodiments, when the detachable connection between the first connector 16 and the second connector 27 is a plug-in connection, the structure of the first connector 16 can be a plug, and accordingly, the structure of the second connector 27 is a socket that can be plugged into the plug;

[0096] In some other optional embodiments, Figures 4-5 as well as Figures 14-15As shown, when the detachable connection between the first connecting member 16 and the second connecting member 27 is a magnetic connection, the first connecting member 16 includes at least one first magnetic member 161, and the second connecting member 27 includes at least one second magnetic member 271. The at least one first magnetic member 161 and the at least one second magnetic member 271 attract each other, wherein, in a specific implementation, at least one of the first magnetic member 161 and the second magnetic member 271 is a magnet. For example, both the first magnetic member 161 and the second magnetic member 271 are magnets. For another example, one of the first magnetic member 161 and the second magnetic member 271 is a magnet, and the other is a magnetic body made of a magnetic conductive material (for example, a magnetic conductive material such as iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as it can meet the use requirements, this embodiment does not impose specific restrictions on the structural form of the first magnetic member 161 and the second magnetic member 271.

[0097] In this embodiment, it should be noted that in some specific application scenarios, the first control circuit board 13 may obtain information about the remaining amount of aerosol-forming material in the storage cavity 213 as detected by the second control circuit board 25, and control the flexible display assembly to display the remaining amount of the aerosol-forming material. Furthermore, the first control circuit board 13 may also simultaneously obtain information about the remaining charge of the second battery 24 and the remaining charge of the first battery 12 as detected by the second control circuit board 25, and control the flexible display assembly to display the current remaining charge of the aerosol generating system (i.e., the sum of the remaining charge of the first battery 12 and the remaining charge of the second battery 24).

[0098] The second display assembly 29 is used to display second visual information. One end of the second display assembly 29 and the first display assembly 14 are located on the same side of the aerosol generating system, and the resolution of the second display assembly 29 is different from that of the first display assembly 14. Therefore, by cooperating with the second display assembly 29 and the first display assembly 14, it is possible to effectively display certain images at low cost. Specifically, the pixel pitch of the second display assembly 29 is smaller than the pixel pitch of the first display assembly 14, and the resolution of the second display assembly 29 is greater than the resolution of the first display assembly 14. The smoothness and detail of the image displayed by the second display assembly 29 are better. Therefore, the second display assembly 29 can be used to display images of rapidly moving objects such as the sun or the earth, that is, images of the sun or the earth are the second visual information. The first display assembly 14 can be used to display images of other planets or satellites that are slowly moving around the sun or the earth, that is, images of the planets or satellites are the first visual information.

[0099] Therefore, the advantages of the first display component 14 and the second display component 29 are exerted, and the cost is reduced well. In addition, the first display component 14 and the second display component 29 can be combined to display a fountain, a spray or fireworks, etc. The second display component 29 can be a hard liquid crystal display screen or an organic light-emitting diode display screen, etc. In the embodiment, the second display component 29 is a liquid crystal display screen. It can be understood that the pixel pitch refers to the distance between two adjacent pixels on the display screen.

[0100] In another embodiment, the first housing 11 is provided with a first picture fusion notch, and the first display component 14 is provided with a second picture fusion notch corresponding to the position of the first picture fusion notch. At least part of the second display component 29 corresponds to the position of the first picture fusion notch, so that at least part of the second visualized information is displayed from the area where the first picture fusion notch is located. Therefore, more rich patterns can be displayed.

[0101] Further, please refer to Figures 1-3 In some optional embodiments of the present application, the aerosol generating device 2 further comprises an airflow sensor 28 electrically connected to the second control circuit board 25, the airflow sensor 28 is located on the airflow flow path of the air channel 212, and the second control circuit board 25 is configured to control the energization of the atomization core 22 in response to the suction signal sent by the airflow sensor 28.

[0102] In the embodiment, the arrangement of the airflow sensor 28 enables the aerosol generating device 2 to work more intelligently, thereby improving the user's experience. Specifically, when the user bites the mouthpiece 23 to suck, a suction airflow will be formed on the airflow flow path of the air channel 212, which will trigger the airflow sensor 28 to act, so that the airflow sensor 28 will send a suction signal to the second control circuit board 25 to represent that the user is sucking, and when the second control circuit board 25 receives the suction signal, the second control circuit board 25 controls the energization of the atomization core 22, and the atomization core 22 is heated to atomize the aerosol-forming substance drawn from the storage cavity 213 into aerosol for the user to smoke. When the user stops sucking, the airflow sensor 28 will send a stop signal to the second control circuit board 25 to represent that the user has stopped sucking, and when the second control circuit board 25 receives the stop signal, the control circuit board controls the de-energization of the atomization core 22 to stop working.
