A first positioning portion 324 extends axially downward along the inner edge of the light guide portion 323 on the side of the first plate 321 facing away from the boss 322, thereby increasing the area of the light guide member 32 that receives light. The first positioning portion 324 includes a first latch 3241. When the light guide member 32 is installed, the edge of the surface of the first plate body 321 facing away from the boss 322 abuts against the bottom surface of the limiting groove 14, that is, the light guide part 323 abuts against the bottom surface of the limiting groove 14, the first positioning part 324 passes through the first through hole 132, and the first clip 3241 is engaged with the bottom surface of the positioning protrusion 131 to fix the light guide member 32. At the same time, the first positioning part 324 increases the area of the light guide member 32 that receives light.
[0040] See also Figure 7 、 Figure 8 as well as Figure 11 As shown, the light shielding member 31 includes a second plate 311. The light shielding member 31 is assembled to the side of the light guide 32 where the boss 322 is provided. The light shielding member 31 is in contact with the surface of the boss 322 to expose the light guide portion 323 and block light emitted from the boss. The second plate 311 is provided with a second positioning portion 312 that protrudes toward the light guide 32. The light guide 32 is provided with a positioning hole 325 that matches the second positioning portion 312. When the light shielding member 31 is installed on the light guide 32, the second positioning portion 312 passes through the positioning hole 325 to fix the radial position between the light shielding member 31 and the light guide 32. The second plate 311 is provided with a second clip 313 that extends toward the light guide 32. The light guide 32 is provided with a connecting hole 326 that matches the second clip 313. When the light shielding member 31 is mounted on the light guide member 32, the second buckle 313 passes through the connection hole 326 and engages with the connection hole 326 to assemble the light guide assembly 30. The light shielding member 31 is in contact with the surface of the boss 322 to block part of the light emitted from the boss 322.
[0041] See also Figure 1 and Figure 12 As shown, the light board 20 is mounted on the bottom wall 12, specifically within the projection of the boss 322 onto the bottom wall 12. Specifically, a plurality of lamp beads 21 are provided on the side of the light board 20 facing away from the bottom wall 12. The lamp beads 21 are evenly arranged on the surface of the light board 20, making the light emitted from the light board 20 more uniform, and thus making the light emitted from the step surface 3231 more uniform.
[0042] In the embodiment of the present invention, the light guide component 30 is covered on the installation groove 11 of the shell 10 to form a closed space. The light emitted by the lamp board 20 can pass through the light guide member 32, but cannot pass through the light shading member 31 and the shell 10. The light shading member 31 is fitted with the boss 322, the bottom surface of the light guide part 323 is fitted with the limiting groove 14, and the side surface of the first plate 321 is fitted with the peripheral wall 13, so that the light is reflected in the closed space, then refracted by the light guide member 32, and finally emitted through the step surface 3231 on the light guide part 323 of the light guide member 32, so that the emitted light is uniform.
[0043] In some embodiments, as Figure 2 As shown, the step surface 3231 is set as a bevel, convex fillet or chamfered corner, so that the light is emitted evenly. Preferably, the step surface 3231 with a chamfered corner is used so that the light is refracted / reflected between the step surfaces 3231, making the light emitted from the step surface 3231 more even.
[0044] In some embodiments, as Figure 1 and Figure 2 As shown, the surface of the light guide 32 facing the lamp board 20 is processed into a bright surface, specifically including the surface of the first positioning portion 324 facing the lamp board 20 and the surface facing away from the boss 322 surrounded by the first positioning portion 324, which increases the reflection efficiency of the light and makes the step surface 3231 emit light more uniformly.
[0045] In some embodiments, as Figure 1 and Figure 2 As shown, the surface of the boss 322 is matte. The surface of the light guide 323 that contacts the retaining groove 14 is also matte. The side of the first plate 321 is also matte, and the surface of the first positioning portion 324 facing away from the light board 20 is also matte. The matte surface prevents side light leakage, reduces light overflow, improves light reflection efficiency, and makes the light emitted from the step surface 3231 more uniform.
[0046] The aerosol generating device further includes a control module, a power module and an airway, wherein the control module, the power module and the airway are conventional technologies in the art, so their layout and connection are not described in detail here.
