The cells 18 are held on the holder 17. The battery cell 18 is used for supplying power. The battery 18 may be a rechargeable battery or a disposable battery.

The light guide member 19 is preferably arranged in a second region within the housing 11; in other examples, the light guide member 19 may also be disposed in the first region within the housing 11, or across the first region and the second region, for example: the light guide member 19 extends from the wiring board 16 to the vicinity of the through hole 121 after passing through the gap between the wiring board 16 and the housing 11; or the light guide member 19 extends from the wiring board 16 to the left side of the housing 11 after passing through the gap between the first heater 14 and the housing 11. The light guide member 19 extends at least partially within the housing 11; the light guide member 19 may be bent at an angle preferably less than or equal to 90 °; the light guide member 19 may be arranged around a certain member.

The light guide member 19 includes an optical fiber 191 and a light-transmitting prevention member 192 fitted over the optical fiber 191.

The optical fiber 191 may be polymerized using a polymer compound. The optical fiber 191 may be made of one or more optical fiber filaments, and may have a net structure. The optical fiber 191 may be a point light emitting optical fiber or a line light emitting optical fiber. The diameter of the optical fiber 191 is between 0.25mm and 3mm; preferably, the diameter is between 0.25mm and 2.5mm; preferably, the diameter is between 0.25mm and 2mm; preferably, the diameter is between 0.25mm and 1.5mm; preferably, the diameter is between 0.75mm and 1.5mm; in a specific example, the diameter of the optical fiber 191 is 1mm. The optical fiber 191 has a certain flexibility and can be plastically deformed into various shapes, such as a regular shape of a circle, a square (including a rectangle or a square), an ellipse, a bar shape, etc., or other irregular shape. The bending radius of the optical fiber 191 is 4mm to 15mm; preferably, 4mm to 10mm; preferably, 4mm to 8mm; preferably, the diameter is between 4mm and 7mm; preferably, the diameter is between 4mm and 6mm.

In this example, the end portions of both ends of the optical fiber 191 extend out of the light-transmitting prevention member 192, and a portion of the optical fiber 191 exposed out of the light-transmitting prevention member 192 may be wire-lighted; of course, it is also possible to keep the ends of the optical fibers 191 flush with the ends of the light-transmitting preventing member 192 in one-to-one correspondence.

One end of the optical fiber 191 is disposed near the light emitting element 161 after passing through the fixing hole 1711, and one end of the optical fiber 191 is fixed by the fixing hole 1711, so that the end of the one end of the optical fiber 191 faces the light emitting element 161 or the end of the one end of the optical fiber 191 is prevented from being misplaced with the light emitting element 161; of course, the fixing of one end of the optical fiber 191 may be achieved by other fixing members. The end of the optical fiber 191 at one end is preferably configured as a substantially flat surface, and the light emitting element 161 has a corresponding substantially flat surface. The end of one end of the optical fiber 191 may be spaced from the light emitting element 161 by a distance as small as possible, typically 0.05mm to 0.5mm; preferably, the diameter is between 0.05mm and 0.2mm; further preferably, the diameter is 0.05mm to 0.15mm; in a specific example, the end of the optical fiber 191 is spaced apart from the light emitting element 161 by a distance of 0.1mm. The end of the optical fiber 191 may be in contact with the light emitting element 161, so that as much light as possible emitted from the light emitting element 161 is incident into the optical fiber 191. In an example, a color filter may be disposed between an end of one end of the optical fiber 191 and the light emitting element 161, and the color filter may change the color of the light beam so that the color light may enter the optical fiber 191.

The other end of the optical fiber 191 passes through the fixing groove 1721 and then is disposed near the through hole 132. The end of the other end of the optical fiber 191 is also preferably configured as a substantially flat surface. The other end of the optical fiber 191 may be spaced from the through hole 132 by the distance described above; alternatively, the other end of the optical fiber 191 may extend into the through hole 132. A transparent window or lens may be disposed within the through-hole 132, or within the viewing aperture 111, or between the through-hole 132 and the viewing aperture 111, at least a portion of the material contained within the transparent window being transparent, and the transparent window may be made of a material such as plastic or glass. It should be noted that, in other examples, it is also possible that the through hole 132 is not provided, that is, the other end of the optical fiber 191 is spaced from the window hole 111 or extends into the window hole 111.

The through hole 132 or the viewing aperture 111 forms a light exit. In other examples, the light outlet is not limited to the above case, and may be designed by the user himself; for example, the light outlet may be provided near the through hole 121, and the optical fiber 191 may be capable of guiding the light emitted from the light emitting element 161 into the through hole 121 or the through hole 121 when the cover 122 opens the through hole 121. While the optical fiber 191 is capable of directing light emitted by the light emitting element 161 into the through-hole 121, it may also be used in conjunction with other sensors to detect whether a solid substrate, such as an article, is inserted into the first heater 14 or removed from the first heater 14.

Thus, the light emitted from the light emitting element 161 can be emitted into the optical fiber 191 from the end of one end of the optical fiber 191, and then emitted out of the optical fiber 191 from the end of the other end of the optical fiber 191, and transmitted to the outside of the housing 11 through the through hole 132 and the window hole 111.

The light-transmitting prevention member 192 serves to prevent light incident into the optical fiber 191 from being transmitted out from the side wall of the optical fiber 191. The light-transmitting prevention member 192 is preferably made of a black material including at least one of PVC (polyvinyl chloride), PE (polyethylene), and TPU (polyurethane). The light guide member 19 may have an inner and outer layer structure, i.e., composed of an optical fiber 191 and a light-transmitting preventing member 192; the light-transmitting prevention member 192 may also have a protective function to prevent breakage of the optical fiber 191. The light guide member 19 may have a three-layer or more structure, for example: a separate protective layer is provided between the optical fiber 191 and the light-transmitting prevention member 192 to prevent breakage of the optical fiber 191. It will be appreciated that other functional layers may be provided outside the light-transmitting prevention member 192, and that the light-transmitting prevention member 192 itself may be a multilayer structure.

The temperature resistance value of the light-proof component 192 is preferably more than 80 ℃, so that the light guide component 19 is prevented from being damaged by the higher temperature in the shell 11; the upper limit of the temperature resistance of the light-transmitting member 192 is not limited, and may be generally 100 to 200 ℃. When the light guide member 19 is disposed in or spans into the first region within the housing 11, a material having high temperature resistance, for example, a temperature resistance value of about 100 ℃ may be employed; when the light guide member 19 is arranged in the second region within the housing 11, a material having relatively low temperature resistance may be used.

In other applications, the light emitted by the light emitting element 161 may partially penetrate the side wall of the optical fiber 191, and the light-blocking member 192 may be partially light-transmissive or partially light-blocking.

As shown in fig. 10, in an example, the light-transmitting device further includes another light-transmitting prevention member 162, the light-transmitting prevention member 162 is sleeved outside one end of the light-emitting element 161 and the optical fiber 191, and the light-transmitting prevention member 162 is disposed adjacent to the light-transmitting prevention member 192 with the end of the adjacent end kept in contact; of course, it is also possible that the light-transmitting prevention member 162 is sleeved outside the light-transmitting prevention member 192. Thus, the light emitted from the light emitting element 161 can be emitted into the optical fiber 191 as much as possible by the light-blocking member 162. The light-proof member 162 is made of a silica gel material, and the temperature resistance value thereof is greater than that of the light-proof member 192.

Unlike the example of fig. 10, in other examples, it is also possible to not provide the light-transmitting prevention member 162. Alternatively, the light-transmitting member 192 may be provided outside the light-emitting element 161.

In this example, the body of the optical fiber 191 (extending from one end of the optical fiber 191 to the other end of the optical fiber 191) is disposed at least partially along the gap between the battery cell 18 and the holder 17, so that light emitted away from the light emitting element 161 disposed on the wiring board 16 can be transmitted to the window hole 111 disposed at the front panel of the housing 11. The length of the optical fiber 191 is larger than the dimension of the aerosol-generating device 100 in the thickness direction; alternatively, the length of the optical fiber 191 is greater than 15mm, and the longest length thereof may be 100mm, 90mm, 80mm, 70mm, 60mm, 50mm. It is understood or readily imaginable that the body of the optical fiber 191 is arranged at least partially along the gap between the cell 18 and the housing 11, and/or along the gap between the cell 18 and the upper cover 12, and/or along the gap between the cell 18 and the bottom cover 13, are possible.
