It will be appreciated that the material and structural design of the housing 20 may also refer to existing designs in the related art, and the present application is not limited in any way.

Referring to fig. 4 in combination with fig. 2 and 3, fig. 4 is a schematic structural diagram illustrating another view of the key assembly in the embodiment shown in fig. 3. In some embodiments, as shown in fig. 2 to 4, the key 31 may have a hat-shaped structure as a whole. The material of the key 31 may be aluminum alloy, that is: which may be an aluminum alloy key 31.

In some embodiments, the keys 31 may include: a key body 311 and a flange 312. The top of the key body 311 is provided with a light transmitting portion 310 and a pressing surface 314, and the key body 311 is provided with a receiving cavity 313. The flange 312 is disposed along the bottom circumference of the key main body 311, that is, the flange 312 is an annular flange and contacts the second light shielding member 33.

In some embodiments, the key body 311 may be provided in a cylindrical shape. The light transmitting portion 310 may be disposed in an arc shape, for example, may be disposed in a minor arc shape, or may be disposed in a major arc shape, or may be disposed in a semi-arc shape. The arc length of the light-transmitting portion 310 can be set according to actual needs. For example, the arc length of the light transmitting portion 310 may be set according to the number of light emitting elements 40 to be accommodated. Alternatively, the light transmitting portion 310 may be disposed along an edge of the pressing surface 314. In some embodiments, the light-transmitting portion 310 may be a light-transmitting groove formed on the key 31 or a light-transmitting material disposed in the light-transmitting groove. Specifically, a light-transmitting groove may be formed in the pressing surface 314 of the key body 311 to form the light-transmitting portion 310. Or a light-transmitting groove can be formed on the pressing surface 314 of the key main body 311, and a glue dripping process is adopted to fill the light-transmitting groove with light-transmitting glue, so that a light-transmitting part 310 is formed on the pressing surface 314 of the key main body 311. It should be noted that the process of dropping the adhesive may refer to the process technology means in the related art, and the material of the transparent adhesive may refer to the existing type in the related art, which is not particularly limited in the present application.

In some embodiments, as shown in fig. 4, the key main body 311 is further provided with a pressing lever 3111. The pressing rod 3111 may be inserted through the first shade 32 and press the second shade 33. Specifically, the pressing bar 3111 may be disposed coaxially with the key main body 311, that is: the pressing bar 3111 may be disposed at a center position of a side of the key main body 311 facing away from the pressing surface 314.

In some embodiments, the key body 311 is also provided with a positioning bar 3112. The positioning rod 3112 may also penetrate through the first light shielding member 32 to position the first light shielding member 32 in the accommodating cavity 313 of the key body 311. Specifically, the positioning lever 3112 is disposed adjacent to the pressing lever 3111. The number of the positioning bars 3112 may be set according to specific requirements, for example, one, two, etc., as long as the positioning effect can be achieved.

In some embodiments, the flange 312 of the key 31 may also be notched so that the key 31 may mate with other components of the aerosol-generating device 100.

Referring to fig. 3 again, in some embodiments, the first light shielding member 32 is in interference fit with the key body 311. Further, the shape of the first light shielding member 32 may be cylindrical, which is adapted to the shape of the key body 311. It will be appreciated that although the key body 311 and the first light shielding member 32 are shown in the drawings as being cylindrically shaped, this is not essential and the shape of both may be varied according to specific design requirements, for example, they may be rectangular bodies adapted to each other, or other shapes.

In some embodiments, the N light holes 320 of the first light shielding member 32 are arranged in an arc shape and aligned with the light transmitting portions 310 of the keys 31. Alternatively, the N light holes 320 may be circumferentially disposed at equal intervals on the first light shielding member 32. It is understood that in other embodiments, the N light holes 320 may be circumferentially disposed at different intervals on the first light shielding member 32. Specifically, the shape of each light transmitting hole 320 may be identical, or may be partially identical, or may be completely different. That is, the arc length of the N light holes 320 may be set according to actual needs. For example, the arc lengths of the N light holes 320 may all be the same, i.e., equidistant circumferential settings, or the arc lengths of the N light holes 320 may be partially the same, i.e., equidistant circumferential settings and different equidistant circumferential settings combined, or the arc lengths of the N light holes 320 may all be different, i.e., different equidistant circumferential settings. The N light holes 320 are circumferentially arranged in any manner as long as they can make the emitted light of the light emitting element 40 arc.

Referring to fig. 5 to 8, fig. 5 is a schematic diagram showing a structure of the case and key assembly removing key in the embodiment shown in fig. 2, fig. 6 is a sectional view along A-A of the embodiment shown in fig. 2, fig. 7 is a sectional view along B-B of the embodiment shown in fig. 2, and fig. 8 is a schematic diagram showing a structure of the key assembly assembled with the key in the embodiment shown in fig. 5 in the embodiment shown in fig. 3. As shown in fig. 5, in some embodiments, each two adjacent light holes 320 may be separated by a first light shielding wall 321 to achieve a light shielding effect, so as to reduce light crosstalk of light rays between the adjacent light holes 320. Thus, the light emission of each light emitting element 40 is independently set without interfering with each other. That is, the light-emitting members 40 can be effectively prevented or reduced from being connected with each other.

In some embodiments, the number of light holes 320 may be four. Of course, the number of the light holes 320 may be other numbers, for example, two, three, five, etc. So long as the arc-shaped effect of the light emitted from the light emitting member 40 can be achieved.

In some embodiments, as shown in fig. 3, the first light shielding member 32 is further provided with a through hole 322, which is matched with the pressing rod 3111 of the key main body 311. Wherein, the pressing rod 3111 is inserted through the through hole 322, so that the pressing rod 3111 presses the second shade 33. Specifically, the through hole 322 may be disposed coaxially with the first light shielding member 32, that is: the through hole 322 may be provided at a central position of the first light shielding member 32.

In some embodiments, the first light shielding member 32 is further provided with a positioning hole 323, and the positioning hole 323 is penetrated by the positioning rod 3112, which is adapted to the positioning rod 3112 of the key main body 311. Accordingly, the positioning hole 323 may be disposed adjacent to the through hole 322. Further, the number of the positioning holes 323 may be provided corresponding to the number of the positioning bars 3112.

Referring to fig. 3, 4 and 6 again, the second light shielding member 33 is disposed at the bottom of the first light shielding member 32 and contacts the flange 312 of the key 31. Alternatively, the second light shielding member 33 may be an elastic body and can be deformed when pressed by the pressing bar 3111 of the key 31, so that the key switch 35 is triggered. Specifically, when the key 31 is pressed, the pressing lever 3111 presses the second shade 33, and the second shade 33 further presses the key switch 35 provided on the second shade 33, so that the key switch 35 is triggered. The key switch 35 and the light emitting member 30 are electrically connected to the controller of the aerosol-generating device 100, respectively, so that the key switch 35 is triggered to generate sensing and feedback to the controller, and the controller can control the light emitting member 30 to emit light.

It will be appreciated that the function to be performed when the key switch 35 is activated may be set according to specific needs. For example, when the key switch 35 is triggered, the light emitting element 40 is triggered to emit light, i.e. the light emitting element 40 is turned on, so as to display the electric quantity. When the key switch 35 is activated, not only the aerosol-generating device 100 may be activated, but also the lighting member 40 may be illuminated to display the amount of electricity.

As shown in fig. 3, the second light shielding member 33 has a plate-like structure. Specifically, the second light shielding member 33 may include a support portion 331 and a light shielding portion 332 provided to the support portion 331. The supporting portion 331 is in contact with the flange 312 of the key 31. The light shielding portion 332 may be convexly disposed at the supporting portion 331.

In some embodiments, the supporting portion 331 of the second light shielding member 33 is further provided with a boss 3311 contacting with the flange 312 of the key 31. The protruding pillar 3311 of the second light shielding member 33 may be an elastomer, which is capable of deforming with the pressing of the key 31. Thus, on one hand, by providing the boss 3311 to support the flange 312 of the key 31, the key 31 can be prevented from shaking; on the other hand, it is also possible to avoid the occurrence of a false position when the edge region of the key 31 is pressed, that is, when the edge of the key 31 is pressed, the key switch 35 cannot be triggered, and thus the light emitting member 40 cannot be triggered to emit light.

In some embodiments, the number of posts 3311 may be multiple. A plurality of bosses 3311 are provided around the pressing lever 311. Thus, when the edge of the key 31 is pressed, the pressing rod 311 can still trigger the key switch 35, and further trigger the light emitting member 40 to emit light.

Alternatively, the number of the studs 3311 may be four. Four studs 3311 may be provided at four edges of the support 331 at intervals, namely: four bosses 3311 may be provided around the pressing lever 311. It should be understood that the number of the protruding columns 3311 may be one, two, etc., and the present application is not limited thereto, so long as the phenomenon of the virtual position and/or wobble of the key 31 can be avoided.

In some embodiments, the shape of the shade 332 matches the shape of the first shade 32. Alternatively, the outer diameter of the shade 332 may be equal to the outer diameter of the first shade 32.

Corresponding to the arrangement mode of the N light holes 320 of the first light shielding member 32, the N accommodating holes 3320 of the second light shielding member 33 are arranged in an arc-shaped arrangement at the light shielding portion 332. Accordingly, the N receiving holes 3320 may be disposed at equal intervals or at different intervals Zhou Xiangshe on the light shielding portion 332 of the second light shielding member 33. Wherein, every two adjacent accommodating holes 3320 can be separated by a second shielding wall 3321. Since the N accommodating holes 3320 are aligned with the N light holes 320, the first light shielding wall 321 and the second light shielding wall 3321 may be aligned with each other. Therefore, the N light emitting elements 40 are accommodated in the N accommodating holes 3320 in a one-to-one correspondence manner, and the light beam between the adjacent light holes 320 can be reduced by the common shading effect between the first shading wall 321 and the second shading wall 3321, so as to further reduce or avoid the light beam phenomenon between the light emitting elements 40. That is, in the aerosol-generating device 100 of the present application, by providing the first light shielding member 32 and the second light shielding member 33 and aligning the N light transmitting holes 320 of the first light shielding member 32 with the N receiving holes 3320 of the second light shielding member 33 one by one, the light emitting members 40 received in the respective receiving holes 3320 can be effectively reduced or avoided from generating a light-emitting phenomenon, so that the light emitting members 40 emit light toward the corresponding light transmitting holes 320, thereby forming an arc-shaped light emitting effect, and further clearly displaying the electric quantity of the device main body 10.

In some implementations, the shade 332 is also provided with a protrusion 3323 that contacts the pressing bar 3111. The protrusion 3323 is also deformed by the pressing of the key 31, similar to the boss 3311 of the supporting portion 331.

In some embodiments, a side of the protrusion 3323 facing away from the pressing bar 311 is provided with a receiving groove 330 to receive the key switch 35.

In some embodiments, the materials of the first light shielding member 32 and the second light shielding member 33 may be silicone, for example, black silicone.

Referring again to fig. 3 and 6, in some embodiments, the aerosol-generating device 100 further comprises a circuit board 34. The circuit board 34 may be disposed on a side of the second light shielding member 33 facing away from the first light shielding member 32. The second light shielding member 33 is bonded to the circuit board 34. One side of the key switch 35 is bonded to the circuit board 34, for example, the side of the key switch 35 facing away from the key 31 is bonded to the circuit board 34. The circuit board 34 is provided with N light emitting elements 40 arranged in an arc shape.

In some embodiments, N illuminators 40 are arranged in parallel. Since the brightness of the light emitting element 40 is controlled by the number of the light emitting elements 40 to be lighted, and the brightness thereof is determined by the current magnitude depending on the amount of electricity of the apparatus body 10. Therefore, the number of the light emitting elements 40 is determined by the amount of electricity of the apparatus body 10, that is, the amount of electricity of the apparatus body 10 can be clearly displayed by the brightness of the light emitting elements 40. Specifically, referring to fig. 9 to 12, fig. 9 to 12 are schematic diagrams illustrating the power display effect of the key assembly in the embodiment shown in fig. 8. As shown in fig. 9, when the number of lighting of the light emitting elements 40 is 1, the electric quantity of the apparatus main body 10 is 25%, and the display effect is shown as a segment of arc shape shown by A1. As shown in fig. 10, when the number of lighting of the light emitting members 40 is 2, the electric quantity of the apparatus main body 10 is 50% and the display effect thereof is shown as two arcs presented by A2. As shown in fig. 11, when the number of lighting of the light emitting members 40 is 3, the electric quantity of the apparatus main body 10 is 75%, and the display effect thereof is shown as three arcs presented by A3. As shown in fig. 12, the number of lighted pieces 40 is 4, and the amount of electricity of the apparatus main body 10 is 100% as shown by the four arcs presented by A4.

It should be noted that, although fig. 9 to 12 show the brightness of one to four light emitting elements 40 to display the electric quantity of the apparatus main body 10, this is not the only display mode, but may be displayed by other modes, for example, the lighting quantity of the light emitting elements 40 is 2, the display electric quantity is 25%, the display electric quantity is 50% to 100%, and so on, or the lighting quantity of the light emitting elements 40 is 3, the display electric quantity is 25%, and so on. That is, the amount of the electric power represented by the number of the light emitting elements 40 can be set according to the actual needs, so long as the electric power can be displayed by forming the arc-shaped light emitting effect.

Specifically, the second light shielding member 33 may be adhered to the circuit board 34 using a Pressure sensitive adhesive (Pressure SENSITIVE ADHESIVES, PSA).

Alternatively, the circuit board 34 may be a flexible circuit board 34 (Flexible Printed Circuit abbreviated as FPC). The luminous element 40 may be an LED lamp.

During assembly, N light emitting members 40 may be soldered to the circuit board 34 by SMT (Surface Mounted Technology, SMT) patches, and the N light emitting members 40 are arranged in an arc. The second light shielding member 33 may be adhered to the circuit board 34 using PSA, and the N light emitting members 40 are accommodated in the N accommodating holes 3320 of the second light shielding member 33 one by one. Further, the first light shielding member 32 is interference assembled in the accommodating cavity 313 of the key main body 311, namely: the pressing rod 3111 and the positioning rod 3112 of the key body 311 are respectively inserted through the through hole 322 and the positioning hole 323 of the first light shielding member 32, and the N light transmitting holes 320 of the first light shielding member 32 are aligned with the N receiving holes 3320 of the second light shielding member 33 one by one and aligned with the light transmitting portions 310 of the key 31.

In the aerosol-generating device 100 of the present application, the N light-transmitting holes 320 of the first light-shielding member 32 are aligned with the N receiving holes 3320 of the second light-shielding member 33 as well as the light-transmitting portions 310 of the key 31, so that the light-emitting member 40 received in each receiving hole 3320 can emit light toward the corresponding light-transmitting hole 320, thereby reducing the crosstalk of light between adjacent light-transmitting holes 320. Therefore, by adopting such a structural design, the light-transmitting portion 310 can clearly display the electric quantity of the device main body 10 according to the light-emitting brightness represented by the lighting quantity of the N light-emitting pieces 40, so as to enrich the design effect of the lamplight and promote the design and the grade sense of the product.

Further, the light-transmitting portion 310 may be arc-shaped, and the N light-transmitting holes 320 and the N accommodating holes 3320 are also correspondingly arc-shaped, so that the N light-emitting elements 40 are also arc-shaped, so that the light-transmitting portion 310 can clearly display the electric quantity of the device main body 10 through the arc-shaped light effect, and user experience is effectively promoted.

Further, due to the combined shading effect of the first shading member 32 and the second shading member 33, the light beam between the adjacent light holes 320 is further reduced, so that the light beam phenomenon between the light emitting members 40 can be effectively reduced or avoided.

The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent processes using the descriptions and the drawings of the present application or directly or indirectly applied to other related technical fields are included in the scope of the present application.
