Description

Technical Field

[0001] This application relates to the technical field of electronic atomization, and particularly relates to a power supply device and an aerosol generating system. Background Art

[0002] An aerosol generating device is an electronic device that can atomize aerosol-forming substances such as tobacco products (such as cigarette sticks), e-liquids, and liquid medicines into aerosol that can be inhaled by users through electric heating.

[0003] In related technologies, in order to improve the battery life of the aerosol generating device so that users can use it outdoors for a long time, a power supply device with a certain battery capacity can be externally attached to the aerosol generating device to replenish electric energy for the aerosol generating device. Among them, in order to facilitate users to know information such as the remaining battery power of the power supply device at any time and intuitively, a display screen capable of displaying information such as the remaining battery power is usually configured on the outside of the power supply device. However, currently, power supply devices with display screens generally have the following problems:

[0004] Since the display screen used is an LED flat display screen, the LED flat display screen can only be installed on one of the outer surfaces of the power supply device (such as the front, back, side, or top surface of the power supply device), resulting in a problem of a small information display range of the power supply device. With the continuous development of electronic atomization technology, more and more information needs to be displayed on the display screen. Therefore, how to increase the information display range of the power supply device so that the power supply device can display more information for users is a technical problem that needs to be solved urgently by those skilled in the art.

[0069] Please refer to Figures 1 - 10 and Figures 13 - 18 , an embodiment of the present application provides a power supply device 1, which is used in combination with an aerosol generating device 2 to supply power to 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 flexible display component 14 for displaying visual information, a first electrode component 15 for electrically connecting to the aerosol generating device 2, and a first connector 16 for detachably connecting to the aerosol generating device 2, where:

[0070] The first housing 11 has a plurality of outer surfaces 110 with different orientations along its circumferential direction. Among them, in specific implementation, the first housing 11 can be an integral structure or a split structure assembled from different housing structures, and its specific structural form can be determined according to actual usage needs, and this embodiment does not make specific limitations on this.

[0071] The first control circuit board 13 is electrically connected to the first battery 12. The first control circuit board 13 can be used to control the working state of the flexible display component 14 (for example, controlling the flexible display component 14 to connect to the first battery 12 and display visual information, or controlling the flexible display component 14 to disconnect the electrical connection with the first battery 12 and stop displaying 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. Among them, the structural form of the first control circuit board 13 can specifically be a microcontroller, a processor, a controller, etc., which are mature control devices in the art with control functions.

[0072] The flexible display component 14 is electrically connected to the first control circuit board 13. The flexible display component 14 is installed on the first housing 11 along the circumferential direction of the first housing 11 and covers at least two outer surfaces 110 of the first housing 11. Among them, in some optional embodiments, the structural form of the flexible display component 14 can be a flexible touch screen of types such as a flexible OLED (organic light-emitting diode) touch screen, a flexible AMOLED (active-matrix organic light-emitting diode) touch screen, etc. Moreover, the flexible display component 14 can be fixed to multiple outer surfaces 110 along the circumferential direction of the first housing 11 by means of glue pasting, snap connection, etc. It can be understood here that after the flexible display component 14 is installed on the first housing 11 along the circumferential direction of the first housing 11, the light-emitting surface of the flexible display component 14 is arranged facing away from the first housing 11, so that the user can observe the light information displayed by the flexible display component 14.

[0073] The first electrode assembly 15 is arranged on the surface of the first housing 11 that is not covered by the flexible display component 14, 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, so as to supply power to the aerosol generating device 2. Among them, in some optional embodiments, the structural form of the first electrode assembly 15 can be a non-retractable fixed electrode. At this time, the first electrode assembly 15 includes at least two conductive pins spaced apart on the surface of the first housing 11; in some other optional embodiments, the structural form of the first electrode assembly 15 can also be an elastic electrode with an elastic telescopic function. At this time, the first electrode assembly 15 includes at least two conductive spring pins (as Figure 5 shown). It should be noted here that the specific structural form of the conductive spring pin is already well-known to those skilled in the art and will not be elaborated here.

[0074] The first connecting member 16 is disposed on the surface of the first housing 11 that is not covered by the flexible display assembly 14, and the first connecting member 16 and the first electrode assembly 15 are arranged on the same side of the first housing 11. Here, it can be understood that when the power supply device 1 is used in combination with the aerosol generating device 2, the power supply device 1 can form a detachable connection with the aerosol generating device 2 through the first connecting member 16. Among them, the detachable connection between the power supply device 1 and the aerosol generating device 2 can be a plug-and-play connection, a snap connection, a magnetic attraction connection, etc. Among them, as Figures 4 - 5 shown, when the detachable connection between the power supply device 1 and the aerosol generating device 2 is a magnetic attraction connection, the first connecting member 16 includes at least one first magnetic member 161. Correspondingly, the aerosol generating device 2 is provided with at least one second magnetic member 271 that attracts 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. Another example is that one of the first magnetic member 161 and the second magnetic member 271 is a magnet, and the other is a magnetic conductor made of a magnetic conductive material (such as a magnetic conductive material of the types of iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as the use requirements can be met, the structural forms of the first magnetic member 161 and the second magnetic member 271 are not specifically limited in this embodiment.

[0075] In the technical solution of this embodiment, by using the bendable flexible display assembly 14 to display visual information, and utilizing the bendable characteristic of the flexible display assembly 14 to cover the flexible display assembly 14 along the circumferential direction of the first housing 11 of the power supply device 1 on the outer side surfaces 110 with different orientations of the first housing 11, the display area of the flexible display assembly 14 can be distributed along the circumferential direction of the first housing 11 on the outer side surfaces 110 with different orientations, so as to improve the information display range of the power supply device 1, enabling the power supply device 1 to achieve multi-directional information display. That is, compared with the traditional power supply device with only one outer surface covered by a display screen, the power supply device 1 provided in this embodiment has a larger information display range and can display more visual information for users. For example, 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. are displayed for the user through the flexible display assembly 14.

[0076] In addition, in the power supply device 1 provided in this embodiment, since the first electrode assembly 15 for electrically connecting with the aerosol generating device 2 and the first connecting member 16 for detachably connecting with the aerosol generating device 2 are both disposed on the same surface of the first housing 11 that is not covered by the flexible display assembly 14, it is ensured that the power supply device 1 provided in this embodiment can be detachably assembled with the aerosol generating device 2 into an integrated unit for use, while the display area of the flexible display assembly 14 will not be blocked by the aerosol generating device 2. Thus, it can be ensured that the aerosol generating system formed by the combination of the power supply device 1 and the aerosol generating device 2 has a relatively large information display range, so as to display more visual information for the user in multiple directions.

[0077] Optionally, please refer to Figures 5 - 7 , in some optional embodiments of the present application, the first housing 11 has opposite first end faces 111 and second end faces 112 along its own height direction, and the first housing 11 has four outer surfaces 110 located between the first end face 111 and the second end face 112 along its own circumferential direction. Two of the outer surfaces 110 are arranged back to back along a first direction of the first housing 11, and the other two outer surfaces 110 are arranged back to back along a second direction of the first housing 11. Among these four outer surfaces 110 of the first housing 11, the flexible display assembly 14 is disposed to cover three of the outer surfaces 110, and the first electrode assembly 15 and the first connecting member 16 are both disposed on the remaining one outer surface 110. Among them, the first direction of the first housing 11, the second direction of the first housing 11, and the height direction of the first housing 11 are perpendicular to each other in pairs. Illustratively, as Figures 5 - 6 shown, the four outer surfaces 110 distributed along the circumferential direction of the first housing 11 are respectively the front side surface, the rear side surface, the left side surface, and the right side surface of the first housing 11. The first direction of the first housing 11 is the Figures 5 - 6 front-back direction in Figures 5 - 6 , the second direction of the first housing 11 is the Figures 5 - 6 left-right direction in

[0078] In this embodiment, based on the above structural design, since the outer surfaces 110 of the first housing 11 in three different circumferential orientations are all covered by the flexible display component 14, and the first electrode assembly 15 and the first connecting member 16 are both disposed on the same outer surface of the first housing 11 that is not covered by the flexible display component 14, the power supply device 1 can achieve information display in three different orientations whether it is in a state combined with the aerosol generating device 2 or in a state not combined with the aerosol generating device 2. That is, the user can observe the light information displayed by the flexible display component 14 from three different orientations of the power supply device 1, thereby increasing the information display range of the power supply device 1 and enabling the power supply device 1 to display more visual information for the user in multiple directions.

[0079] Optionally, in some other alternative embodiments of the present application, the information display of the power supply device 1 in four different orientations can also be achieved in the following manner. Specifically:

[0080] As Figure 14 And Figures 17 - 18 shown, the first housing 11 has opposite first end face 111 and second end face 112 in its height direction (illustratively, the first end face 111 of the first housing 11 is the upper end face of the first housing 11, and the second end face 112 of the first housing 11 is the lower end face of the first housing 11). The first housing 11 has four outer surfaces 110 located between the first end face 111 and the second end face 112 in its circumferential direction. Two of the outer surfaces 110 are disposed opposite to each other along the first direction of the first housing 11, and the other two outer surfaces 110 are disposed opposite to each other along the second direction of the first housing 11. The flexible display component 14 is disposed to cover the four outer surfaces 110 of the first housing 11. The first end face 111 is recessed with a receiving cavity 1110 capable of receiving at least a part of the aerosol generating device 2. The receiving cavity 1110 has a cavity wall 11101 disposed facing the opening of the receiving cavity 1110 (this cavity wall 11101 can be regarded as one of the inner surfaces of the first housing 11). The first electrode assembly 15 and the first connecting member 16 are both disposed on this cavity wall 11101. Among them, the first direction of the first housing 11, the second direction of the first housing 11, and the height direction of the first housing 11 are perpendicular to each other in pairs. Illustratively, as Figures 13 - 14 And Figures 17 - 18 shown, the four outer surfaces 110 distributed in the circumferential direction of the first housing 11 are respectively the front side surface, the rear side surface, the left side surface, and the right side surface of the first housing 11. The flexible display component 14 is disposed to cover the front side surface, the rear side surface, the left side surface, and the right side surface of the first housing 11 at the same time.

[0081] In this embodiment, based on the above structural design, since the outer surfaces 110 of the first housing 11 in four different orientations of front, back, left, and right are all covered by the flexible display component 14, and both the first electrode assembly 15 and the first connecting member 16 are disposed on the same surface of the first housing 11 that is not covered by the flexible display component 14, the power supply device 1 can display information for the user in four different orientations of front, back, left, and right whether it is in a combined state with the aerosol generating device 2 or in a state not combined with the aerosol generating device 2. Thus, the information display range of the power supply device 1 is increased, enabling the power supply device 1 to display more visual information for the user in all directions of 360° along its circumference. Moreover, when the power supply device 1 is in a combined state with the aerosol generating device 2, at least a part of the aerosol generating device 2 is located in the receiving cavity 1110 of the first housing 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 combined state with the aerosol generating device 2, the aerosol generating device 2 is simultaneously restricted by the receiving cavity 1110 and the first connecting member 16, making it less likely for the aerosol generating device 2 to become detached from the power supply device 1. In this embodiment, it should be noted that the main difference between the power supply device 1 provided in this embodiment (as shown in Figures 16 - 18 and the power supply device 1 provided in the embodiments shown in Figures 2 - 3 and FIGS. 5-7 lies in the installation 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 component 14. Their internal structural compositions are similar, and those skilled in the art can understand this and will not be elaborated here.

[0082] Furthermore, please refer to Figures 6 - 7 . In some alternative embodiments of the present application, the power supply device 1 further includes a charging interface 17 disposed on the second end face 112 of the first housing 11. The charging interface 17 is electrically connected to the first control circuit board 13. Specifically, in implementation, the structural form of the charging interface 17 can be a USB interface or a Type-C interface, and this embodiment does not make specific limitations thereto. With such a setting, 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, 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 for the user through the flexible display component 14.

[0083] Furthermore, please refer to Figures 6 - 8 and Figures 19 - 20, in some alternative embodiments of the present application, along the height direction of the first housing 11, the flexible display component 14 has opposite first edge 1401 and second edge 1402. Herein, assuming 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 face 111 and the second end face 112 of the first housing 11 is H3, then 0.5H3 ≤ H1 ≤ 0.9H3 and 0.5H3 ≤ H2 ≤ 0.9H3. Exemplarily, assuming H3 is 70 mm, then H1 can be 35 mm, 42 mm, 49 mm, 56 mm, 63 mm, etc., and H2 can be 35 mm, 42 mm, 49 mm, 56 mm, 63 mm, etc. In this embodiment, it can be understood that when the flexible display component 14 is in an unfolded state without being enclosed, if the display area of the flexible display component 14 is a rectangle (as shown in Figure 8 ), then H1 = H2; and when the flexible display component 14 is in an unfolded state without being enclosed, if the display area of the flexible display component 14 is an irregular figure (as shown in Figure 20 ), then H1 < H2.

[0084] 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 14 to be 0.5 to 0.9 times the vertical height between the first end face 111 and the second end face 112 of the first housing 11, it can ensure that the power supply device 1 can have a relatively large 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 14 to be 0.5 to 0.9 times the vertical height between the first end face 111 and the second end face 112 of the first housing 11, it can reduce the risk that when the flexible display component 14 is covered on the plurality of outer surfaces 110 of the first housing 11, due to the uneven installation of the flexible display component 14, some edges of the flexible display component 14 along its own width direction cannot cover the outer surface 110 of the first housing 11, resulting in a sense of abruptness, and further affecting the overall aesthetic appearance of the power supply device 1.

[0085] Further, please refer to Figures 17 - 18, in some alternative embodiments of the present application, the flexible display component 14 is a flexible OLED touch screen or a flexible AMOLED touch screen. An installation groove 113 extending along the circumferential direction of the housing is provided on the outer surface of the first housing 11. The groove wall surface of the installation groove 113 includes at least two outer side surfaces 110. The flexible display component 14 is adaptively installed in the installation groove 113 and covers at least two outer side surfaces 110. It can be understood here that the shape and size of the flexible display component 14 are adapted to the shape and size of the installation groove 113, so that the flexible display component 14 can be adaptively installed in the installation groove 113 of the first housing 11.

[0086] In this embodiment, the provision of the installation groove 113 can, on the one hand, play a certain positioning role in the installation of the flexible display component 14, thus facilitating the installation of the flexible display component 14. On the other hand, it can properly accommodate the flexible display component 14 and prevent the light-emitting surface of the flexible display component 14 from protruding excessively 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 structural composition and working principle of the flexible OLED touch screen or the flexible AMOLED touch screen are already well-known to those skilled in the art and will not be elaborated here.

[0087] In some other alternative embodiments of the present application, in addition to being flexible touch screens such as flexible OLED touch screens and flexible AMOLED touch screens, the structural form of the flexible display component 14 can also be the following structural forms:

[0088] Specifically, please refer to Figures 6 - 10 , the flexible display component 14 includes a display film 146 made of a flexible material and a flexible printed circuit board 141 having circuit traces 1410. A plurality of light-emitting elements 142 electrically connected to the circuit traces 1410 are fixed on one surface of the flexible printed circuit board 141 along the thickness direction of the flexible printed circuit board 141. The surface of the flexible printed circuit board 141 facing away from the plurality of light-emitting elements 142 can be connected to the first housing 11 by means of adhesion (such as double-sided tape) and cover at least two outer side surfaces 110 of the first housing 11. The circuit traces 1410 of the flexible printed circuit board 141 are electrically connected to the first control circuit board 13. The display film 146 can be fixedly connected to the side of the flexible printed circuit board 141 where the plurality of light-emitting elements 142 are provided by means of adhesion (such as double-sided tape, structural adhesive, optical transparent adhesive, etc.) and cover each light-emitting element 142. The display film 146 has a plurality of light-transmitting regions 1461 for the light emitted by the light-emitting elements 142 to pass through. The region of the display film 146 other than the light-transmitting regions 1461 is a light-shielding region 1462.

[0089] In this embodiment, it can be understood that the flexible printed circuit board 141 is also known as an FPC (Flexible Printed Circuit) board, which is a flexible circuit board printed with circuit traces 1410. It has the advantages of good flexibility, light weight, and thin thickness. In the specific manufacturing process, the required flexible printed circuit board 141 can be obtained by printing circuit traces 1410 on a polyimide film or a polyester film. In addition, it can also be understood that the flexible printed circuit board 141 can be used as a mounting carrier for multiple light-emitting elements 142, and the circuit traces 1410 on the flexible printed circuit board 141 can be used as a medium for electrically connecting the multiple light-emitting elements 142 to the first control circuit board 13.

[0090] In this embodiment, it should be noted that in the specific implementation, the light-emitting element 142 can be a component that can emit light when powered on, such as an LED lamp bead. In addition, the light-emitting element 142 can be fixed on the surface of the flexible printed circuit board 141 and electrically connected to the circuit traces 1410 of the flexible printed circuit board 141 by means of welding, bonding (such as bonding through insulating glue or conductive glue), etc.

[0091] In this embodiment, it should also be noted that in specific implementation, the material of the display diaphragm 146 can be flexible materials such as polyimide (abbreviation: PI), polyethylene terephthalate (abbreviation: PET), polyethylene naphthalate (abbreviation: PEN), liquid crystal polymer (abbreviation: LCP), polyvinyl alcohol (abbreviation: PVA), polydimethylsiloxane (abbreviation: PDMS), etc., as long as it can meet the usage requirements. This embodiment does not make specific restrictions on the specific material of the display diaphragm 146. Among them, in some alternative implementation manners, when the display diaphragm 146 is made of a transparent flexible material, a light-transmitting region 1461 and a light-shielding region 1462 can be formed on the display diaphragm 146 by means such as coating light-shielding ink. For example, when the display diaphragm 146 is a transparent polyimide film, the light-shielding ink can be coated on the surface of the polyimide film in a predetermined manner. The region of the polyimide film coated with the light-shielding ink can be regarded as the light-shielding region 1462 of the display diaphragm 146, and the region of the polyimide film not coated with the light-shielding ink can be regarded as the light-transmitting region 1461 of the display diaphragm 146. In some other alternative implementation manners, when the display diaphragm 146 is made of an opaque flexible material, a light-transmitting region 1461 and a light-shielding region 1462 can be formed on the display diaphragm 146 by means such as laser engraving. For example, when the display diaphragm 146 is an opaque PET film, the required light-transmitting region 1461 (in this case, the light-transmitting region 1461 is essentially a through hole) can be engraved on the surface of the PET film by laser engraving, and the region of the PET film not engraved forms the light-shielding region 1462. Of course, the display diaphragm 146 can also be other film structures in the art that have a light-transmitting region 1461 and a light-shielding region 1462. For example, in some other alternative implementation manners, the display diaphragm 146 can also be a PET color film in the art that has a light-transmitting region 1461 and a light-shielding region 1462, as long as it can meet the usage requirements. This embodiment does not make specific restrictions on this.In addition, during specific implementation, the number of the light-transmitting areas 1461 provided on the display diaphragm 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 make specific limitations thereto. Optionally, the shape of the light-transmitting area 1461 can be a character 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, the light display information of the corresponding shape can be displayed. For example, when the light emitted by the light-emitting element 142 reaches the light-transmitting area 1461 in the shape of a letter, the user can observe the glowing letter on the surface of the display diaphragm 146. Thus, by combining a plurality of light-transmitting areas 1461 with different shapes, a variety of light display information with different shapes can be obtained, and various information of the power supply device 1 can be represented by combining the light display information with different shapes, 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, the preset pattern information, etc. In addition, the number of the 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 this embodiment also does not make specific limitations thereto.

[0092] In this embodiment, based on the above structural design, the first control circuit board 13 can control a plurality of light-emitting elements 142 to be powered on and emit light or powered off and stop emitting light. When the plurality of light-emitting elements 142 are powered on and emit light, the light emitted can be displayed in the light-transmitting areas 1461 of the display diaphragm 146. That is, the light-transmitting areas 1461 of the display diaphragm 146 can be used as the light display areas of the flexible display assembly 14, thereby realizing the display function of the flexible display assembly 14. In addition, since both the display diaphragm 146 and the flexible printed circuit board 141 are flexible structures, the display assembly formed by laminating the display diaphragm 146 and the flexible printed circuit board 141 is also a flexible structure, so that the flexible display assembly 14 has the characteristic of being bendable. Moreover, compared with a flexible OLED touch screen, a flexible AMOLED touch screen or an LED flat display screen, the flexible display assembly 14 provided in this embodiment has the advantages of simple structure and low cost.

[0093] Further, please refer to Figures 5 - 7, in some alternative embodiments of the present application, the power supply device 1 further includes a protective shell 18 made of a light-transmitting material (such as glass, acrylic, etc.). An installation groove 113 extending along the circumferential direction of the first housing 11 is provided on the outer surface of the first housing 11. The groove wall surface of the installation groove 113 includes at least two outer side surfaces 110. The flexible display component 14 is fixed in the installation groove 113 and covers at least two outer side surfaces 110. The protective shell 18 is installed on the first housing 11 to cover the flexible display component 14, and 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.

[0094] In this embodiment, on the one hand, the setting of the light-transmitting protective shell 18 can not only ensure that the user can observe the light information displayed by the flexible display component 14 through the protective shell 18, but also protect the flexible display component 14 to reduce the risk of damage to the light-emitting element 142 caused by the impact of foreign objects on the flexible display component 14. On the other hand, since there is a gap L between the inner surface of the protective shell 18 and the display film 146, on the one hand, this gap L can be used as a heat dissipation space for the flexible display component 14 to improve the heat dissipation efficiency during the operation of the flexible display component 14. On the other hand, it can prevent the inner surface of the protective shell 18 from squeezing the flexible display component 14 and damaging the light-emitting element 142 in the flexible display component 14.

[0095] Further, please refer to Figure 11 , in some alternative embodiments of the present application, the flexible display component 14 further includes a flexible diffusion film 145 clamped between the flexible printed circuit board 141 and the display film 146. The flexible diffusion film 145 covers each light-transmitting area 1461 of the display film 146.

[0096] In this embodiment, the setting of the flexible diffusion film 145 can evenly diffuse the light emitted by the light-emitting element 142 on the premise that the flexible display component 14 can be bent, so that the light emitted by the light-emitting element 142 can be more evenly diffused onto the light-transmitting area 1461 of the display film 146, thereby improving the light display uniformity of the flexible display component 14. Among them, in specific implementation, the flexible diffusion 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 a light diffusion function, as long as it can meet the use requirements. This embodiment does not make specific limitations on this. Optionally, in some implementation manners, the flexible diffusion film 145 can be a fluorescent ink thin film sheet with a yellow color. In this embodiment, it should be noted that in specific implementation, the flexible diffusion film 145 and the display film 146 as well as the flexible diffusion film 145 and the flexible printed circuit board 141 can be laminated together by means of glue pasting.

[0097] Further, please continue to refer to Figure 11 , in some alternative embodiments of the present application, the flexible display assembly 14 further includes a flexible light-shielding sheet 144 sandwiched between the flexible printed circuit board 141 and the display film 146. A plurality of light-transmitting holes 1441 are formed in the flexible light-shielding sheet 144, and at least one light-emitting element 142 is disposed in each light-transmitting hole 1441. Each light-transmitting region 1461 is disposed opposite to at least one light-transmitting hole 1441. It should be noted here that in specific implementation, the number of the light-transmitting holes 1441 on the flexible light-shielding sheet 144 and the number of the light-transmitting regions 1461 provided on the display film 146 may be the same or different, as long as the usage requirements can be met, and this embodiment does not make specific limitations thereto. In addition, the shape and size of the light-transmitting holes 1441 on the flexible light-shielding sheet 144 and the shape and size of the corresponding light-transmitting regions 1461 on the display film 146 may be the same or different, as long as the usage requirements can be met, and this embodiment also does not make specific limitations thereto.

[0098] In this embodiment, the provision of the flexible light-shielding sheet 144 can reduce the risk of light leakage of the flexible display assembly 14 on the premise that the flexible display assembly 14 can still be bent, so that the light emitted by the light-emitting element 142 can be transmitted more fully and concentratedly to the light-transmitting regions 1461 of the display film 146, thereby facilitating the improvement of the light display effect of the flexible display assembly 14. Among them, in specific implementation, the flexible light-shielding sheet 144 can be made of flexible materials such as non-transparent silica gel, rubber, silicone rubber, sponge, etc., as long as the usage requirements can be met, and this embodiment does not make specific limitations thereto. In this embodiment, it should be noted that in some implementation manners, 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 means of glue adhesion.

[0099] Further, please continue to refer to Figure 11 , in some alternative embodiments of the present application, the flexible display assembly 14 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.

[0100] In this embodiment, the flexible reflective layer 143 can improve the lighting display effect of the flexible display component 14 on the premise of ensuring that the flexible display component 14 can still be bent. Specifically, in some usage scenarios, a part of the light emitted by the light-emitting element 142 is reflected after irradiating the light-transmitting area 1461 of the display diaphragm 146 (or the flexible diffusion film 145). The existence of the flexible reflective layer 143 can reflect this part of the reflected light back to the light-transmitting area 1461 of the display diaphragm 146 to a certain extent, thereby improving the utilization rate of light and enabling the flexible display component 14 to obtain a better lighting display effect. Among them, in specific implementation, the flexible reflective layer 143 can be a flexible reflective film (such as a transparent polyimide film), or a paint layer (optionally, a white paint layer can be used as the flexible reflective layer 143 to achieve a better reflective effect), or a reflective ink layer, as long as it can meet the usage requirements, and this embodiment does not make specific restrictions on this. In this embodiment, it should be noted that in some implementation manners, the flexible reflective layer 143 and the display diaphragm 146 can be laminated together by means of glue adhesion.

[0101] Here, it should be supplemented that in the structural design of the flexible display component 14 including the display diaphragm 146, the flexible diffusion film 145, the flexible light-shielding sheet 144, and the flexible reflective layer 143 can exist simultaneously, or one or two of them can be selected for setting, which is determined according to actual usage requirements, and this embodiment does not make specific restrictions on this. Among them, preferably, in order to obtain a better lighting display effect, as Figure 11 shown, the display diaphragm 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 laminated in sequence, and among them, adjacent two-layer structures can be laminated together by means of glue adhesion.

[0102] Furthermore, please refer to Figures 8 - 10 , in some alternative embodiments of the present application, one side surface of the flexible printed circuit board 141 where a plurality of light-emitting elements 142 are provided has a first mounting area 1411 and a second mounting area 1412 that are connected to each other. The area of the first mounting area 1411 is larger than the area of the second mounting area 1412. The second mounting area 1412 is exposed and disposed at the edge position of the flexible display component 14 (for example, assuming that the flexible display component 14 is a strip-shaped sheet with a certain length and width, then the second mounting area 1412 is located at the length edge or the width edge of the flexible display component 14). A plurality of light-emitting elements 142 are fixed in the first mounting area 1411, and at least one of a current input interface 147, a current driving element 148, and a plurality of metal test points 149 electrically connected to the circuit trace 1410 is disposed in the second mounting area 1412.

[0103] 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, only one end of a flexible cable needs to be plugged into the current input interface 147, and the other end of the flexible cable is plugged into the current output interface (not shown in the figure) of the first control circuit board 13. In this way, the electrical connection between the circuit trace 1410 of the flexible printed circuit board 141 and the first control circuit board 13 can be quickly achieved, and the operation is very convenient. Among them, the structural form of the current input interface 147 can be a socket-type connector or other types of communication interfaces, as long as it can meet the usage requirements. This embodiment does not make specific restrictions on this. Correspondingly, the structural form of the current output interface of the first control circuit board 13 can be the same as that of the current input interface 147 of the flexible printed circuit board 141.

[0104] In this embodiment, the provision of the current driving element 148 enables the first control circuit board 13 to control each light-emitting element 142 in the flexible display module 14 to emit light in a preset manner after the first battery 12 is connected through the current input interface 147, so as to display the required information on the display film 146. It should be noted here that in specific implementation, the current driving element 148 can adopt a general driving chip in the art. Since its specific structure and operating principle are well known to those skilled in the art, they will not be elaborated here.

[0105] In this embodiment, the provision of multiple metal test points 149 facilitates the tester to perform corresponding function tests or fault tests on the flexible display module 14.

[0106] Further, considering that in specific practice, when using a display film 146 with a relatively long single-piece length to cover the light-emitting elements 142 in each of the first mounting areas 1411 simultaneously, it is very easy to have a problem that some of the light-emitting elements 142 are damaged during the process of installing the display component on the multiple outer surfaces 110 of the first housing 11. The reason is that during the process of winding the display component of this embodiment around the circumferential direction of the first housing 11 on the multiple outer surfaces 110 of the first housing 11, it is inevitable that the display component needs to be bent multiple times. If the display component needs to be reinstalled due to improper installation, more bends of the display component are required. And each time the display component is bent, the entire display film 146 will be stretched to varying degrees and local stress concentration will occur. Moreover, the greater the degree of bending of the display component, the greater the degree of stretching of the display film 146 and the more obvious the local stress concentration phenomenon. And each time the display film 146 is stretched, it will cause varying degrees of extrusion to the light-emitting elements 142, and the part of the display film 146 where the local stress concentration phenomenon appears causes the greatest degree of extrusion to the light-emitting elements 142. Therefore, when the display component is bent repeatedly, especially when the degree of bending is relatively large, it is very easy to cause some of the light-emitting elements 142 to be crushed by the display film 146.

[0107] Based on the above findings, in order to solve the technical problem that when using a display film 146 with a relatively long single-piece length to cover the light-emitting elements 142 in each of the first mounting areas 1411 simultaneously, some of the light-emitting elements 142 are easily damaged during the process of installing the display component on the multiple outer surfaces 110 of the first housing 11, multiple flexible display films 1460 with relatively short single-piece lengths can be used to replace the display film 146 with a relatively long single-piece length. Specifically, please refer to Figure 6 , Figures 8 - 10 and Figure 12 . In some alternative embodiments of the present application, at least two first mounting areas 1411 are provided on one surface of the flexible printed circuit board 141 along its thickness direction, and the at least two first mounting areas 1411 are arranged at intervals along the length direction of the flexible printed circuit board 141. A plurality of light-emitting elements 142 are fixed in each of the first mounting areas 1411; the display film 146 includes at least two flexible display films 1460 arranged at intervals, each flexible display film 1460 covers one first mounting area 1411, and each flexible display film 1460 has 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.

[0108] In the technical solution of this embodiment, since each first installation area 1411 is separately covered by a flexible display film 1460 with a relatively short length, and each flexible display film 1460 is separately arranged and not a monolithic film structure connected to each other, 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 (such as the front surface of the first housing 11) of the first housing 11, during the process of covering the second flexible display film 1460 on the second outer surface 110 (such as the right surface of the first housing 11) by bending the display component once, the first flexible display film 1460 will not be stretched due to this bending of the display component. Furthermore, during this process, the first flexible display film 1460 will not squeeze the light-emitting element 142 opposite to it, so that during the process of installing the display component on multiple outer surfaces 110 of the first housing 11, the risk that some light-emitting elements 142 are damaged by the flexible display film 1460 can be effectively reduced.

[0109] In this embodiment, it should be supplemented that in some specific application scenarios, in order to improve the manufacturing efficiency of the flexible display component 14, multiple flexible display films 1460 with relatively short lengths can be obtained by cutting a single display film 146 with a relatively long length. For example, after using a single display film 146 with a relatively long length to cover the light-emitting elements 142 in each first installation area 1411, and before installing the display component on multiple outer surfaces 110 of the first housing 11, the parts of the single display film 146 with a relatively long length that do not cover the first installation area 1411 can be cut, so that multiple flexible display films 1460 with short lengths and spaced apart can be obtained in the length direction of the display component.

[0110] Correspondingly, please refer to Figures 1 - 5 and Figures 13 - 16 , the embodiment of the present application further provides an aerosol generating system, which includes an aerosol generating device 2 and the power supply device 1 in any of the above embodiments (such as Figures 2 - 3 , Figures 5 - 12 , Figure 14 and Figures 16 - 20 shown), wherein the aerosol generating device 2 includes a second housing 21, an atomization core 22, a mouthpiece 23, a second electrode assembly 26, a second connector 27, a second battery 24 installed in the second housing 21, and a second control circuit board 25 installed in the second housing 21, wherein:

[0111] The second housing 21 has a connection surface 211 for connecting to the first housing 11. Inside the second housing 21, there is an air passage 212 and a storage chamber 213 for storing the aerosol-forming substance. The aerosol-forming substance can be substances such as e-liquid or liquid medicine, which can be determined according to the actual usage needs of the user. Specifically, in implementation, the second housing 21 can be an integral structure or a split structure assembled from different housing structures. Its specific structural form can be determined according to actual usage needs, and this embodiment does not make specific limitations on this.

[0112] The atomization core 22 is installed on the airflow circulation path of the air passage 212 so that the aerosol generated by the atomization core 22 can be carried away by the airflow formed in the air passage 212 and discharged to the outside for the user to inhale. Moreover, the atomization core 22 is in communication with the storage chamber 213 so that the atomization core 22 can suck the aerosol-forming substance from the storage chamber 213 for heating and atomization. It should be noted here that the specific structural composition, working principle of the atomization core 22, and the communication method between the atomization core 22 and the storage chamber 213 are already well-known to those skilled in the art and will not be elaborated here.

[0113] The mouthpiece 23 is provided on one end face of the second housing 21 along its height direction, and the mouthpiece 23 is in communication with the air outlet end of the air passage 212. When the user bites the mouthpiece 23 to suck, outside air can enter the air passage 212 from the air inlet end of the air passage 212 and form a suction airflow. When the suction airflow flows through the atomization core 22, it takes away the aerosol generated by the atomization core 22, and the aerosol finally flows out from the mouthpiece 23 to the user's mouth and is inhaled by the user.

[0114] The second control circuit board 25 is electrically connected to the second battery 24 and the atomization core 22 respectively. The second control circuit board 25 is mainly used to control the working state of the atomization core 22. For example, it controls the atomization core 22 to connect to the second battery 24 and work at a predetermined power or controls the atomization core 22 to cut off the power and stop working. The structural form of the second control circuit board 25 can specifically be a single-chip microcomputer, a processor, a controller, etc., which are mature control devices in the art.

[0115] The second electrode assembly 26 is disposed on the connection surface 211 of the second housing 21. The second electrode assembly 26 is electrically connected to the second control circuit board 25 and is in electrical contact with the first electrode assembly 15 of the power supply device 1, thereby realizing the electrical connection between the aerosol generating device 2 and the power supply device 1, such that the first battery 12 in the power supply device 1 can charge the second battery 24 in the aerosol generating device 2. In 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, 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 pin and the other is a conductive spring pin. Exemplarily, as Figures 4 - 5 and Figures 15 - 16 shown, the structural form of the first electrode assembly 15 is a conductive spring pin, and the structural form of the second electrode assembly 26 is a conductive pin.

[0116] The second connector 27 is disposed on the connection surface 211 of the second housing 21, and the second connector 27 is detachably connected to the first connector 16. In 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 attraction connection, etc., as long as it can meet the usage requirements. This embodiment does not make specific limitations thereto. It can be understood that in some alternative implementation manners, when the detachable connection between the first connector 16 and the second connector 27 is a snap connection, the structural form of the first connector 16 can be a snap, and correspondingly, the structural form of the second connector 27 is a slot that can be engaged with the snap; in other alternative implementation manners, when the detachable connection between the first connector 16 and the second connector 27 is a plug-in connection, the structural form of the first connector 16 can be a plug, and correspondingly, the structural form of the second connector 27 is a socket that can be plugged into the plug; in still other alternative implementation manners, as Figures 4 - 5 and Figures 15 - 16 shown, when the detachable connection between the first connector 16 and the second connector 27 is a magnetic attraction connection, the first connector 16 includes at least one first magnetic member 161, and the second connector 27 includes at least one second magnetic member 271. At least one first magnetic member 161 and at least one second magnetic member 271 attract each other. In 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. Another example is that one of the first magnetic member 161 and the second magnetic member 271 is a magnet, and the other is a magnetic conductor made of a magnetic conductive material (such as ferromagnetic materials like iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as it can meet the usage requirements, this embodiment does not make specific limitations on the structural forms of the first magnetic member 161 and the second magnetic member 271.

[0117] In this embodiment, it should be noted that in some specific application scenarios, the first control circuit board 13 can obtain the remaining amount information of the aerosol-forming substance in the storage cavity 213 detected by the second control circuit board 25, and control the flexible display component 14 to display the remaining amount information of the aerosol-forming substance. In addition, the first control circuit board 13 can also simultaneously obtain the remaining power of the second battery 24 detected by the second control circuit board 25 and detect the remaining power of the first battery 12, and control the flexible display component 14 to display the current remaining power of the aerosol generation system (i.e., the sum of the remaining power of the first battery 12 and the remaining power of the second battery 24).

[0118] Furthermore, please refer to Figures 1 - 3 , in some alternative embodiments of the present application, the aerosol generation device 2 further includes an airflow sensor 28 electrically connected to the second control circuit board 25. The airflow sensor 28 is located on the airflow passage of the airway 212, and the second control circuit board 25 is configured to control the atomization core 22 to be powered on and work in response to the suction signal sent by the airflow sensor 28.

[0119] In this embodiment, the setting of the airflow sensor 28 enables the aerosol generation device 2 to work more intelligently, thereby improving the user experience. Specifically, when the user bites the mouthpiece 23 to suck, a suction airflow will be formed on the airflow passage of the airway 212. This suction airflow will trigger the airflow sensor 28 to act, causing the airflow sensor 28 to send a suction signal indicating that the user is sucking to the second control circuit board 25. When the second control circuit board 25 receives this suction signal, the second control circuit board 25 controls the atomization core 22 to be powered on and work. The atomization core 22 is powered on and heated to atomize the aerosol-forming substance sucked from the storage cavity 213 into an aerosol that can be inhaled by the user. When the user stops sucking, the airflow sensor 28 will send a stop signal indicating that the user has stopped sucking to the second control circuit board 25. When the second control circuit board 25 receives this stop signal, the control circuit board controls the atomization core 22 to be powered off and stop working.

[0120] It should be noted here that other contents of the power supply device 1 and the aerosol generation device 2 disclosed in the present application can be referred to the prior art and will not be elaborated here.

[0121] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. All equivalent structural transformations made under the concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
