The inner part 63 circumferentially surrounds the button 59 and the lighting assembly 61.
[0233] Fig. 7 shows a sectional view designated in Fig. 1 as II-II. In Fig. 7, it is shown that the inner part 63 is in contact with the outer surface of the main part 65 around the button 59 and the lighting assembly 61. The inner part 63 may be in close contact with the outer surface of the main part 65. The inner part 63 may be a plastic part. The inner part 63 may be impermeable to water. The inner part 63 has a surface 67 (the first surface) facing outward toward the second part 21 of the housing and away from the main part 65. The outer surface 67 (the first surface) of the inner part 63 may be parallel to the inner surface 69 (the second surface) of the second part 21 of the housing. The outer surface 67 (the first surface) of the inner part 63 is substantially parallel to the inner surface 69 (the second surface) of the second part 21 of the housing.Between the inner part 63 and the second part 21 of the housing there is a double-sided adhesive tape 71. The first adhesive side 73 of the double-sided adhesive tape 71 is glued to the outer surface 67 (the first surface) of the inner part 63. The opposite second adhesive surface 75 of the double-sided adhesive tape 71 is glued to the inner surface 69 (the second surface) of the second part 21 of the housing. Thus, the double-sided adhesive tape 71 is glued or connected to both the inner part 63 and the second part 21 of the housing.
[0234] Double-sided adhesive tape 71 extends circumferentially around the button hole 55 and around the light opening 57. Double-sided adhesive tape 71 forms a seal between the inner portion 63 and the second portion 21 of the housing. By using double-sided adhesive tape 71, the fluid entering through the button hole 55 or the fluid entering through the light opening 57 can be prevented from leaking into the inner compartments of the aerosol generating device 3.
[0235] In the embodiment of Fig. 7, the lighting assembly 61 comprises a light guide 77 and a light source 79. The light guide 77 may be configured to direct the light generated by the light source 79. The light source 79 may, for example, comprise one or more LEDs. In the illustrated embodiment, both the light guide 77 and the light source 79 are visible from the outside through the light opening 57. Alternatively, the lighting assembly 61 may not be directly visible through the light opening 57, but may be configured to emit artificial light through the light opening 57.
[0236] In the illustrated embodiment, the shape of the adhesive tape 71 corresponds to the shape of the outer surface 67 of the inner portion 63. This can improve the adhesive bonding strength between the inner portion 63 and the second housing portion 21. However, the double-sided adhesive tape 71 may also have different shapes. For example, the double-sided adhesive tape 71 may comprise a first annular portion circumferentially surrounding the button hole 55 and a second annular portion circumferentially surrounding the light opening 57. The first annular portion and the second annular portion may be a single unit or separate parts.
[0237] Fig. 8 shows a schematic perspective view of the distal end 13 of the aerosol generating device 3. A connection port 81 is provided at the distal end 13. The connection port 81 is configured to be connected to an external connector for transmitting data or power supply, or both, between the connection port 81 and the external connector. For example, the battery of the aerosol generating device 3 can be charged through the connection port 81. The connection port 81 can be a USB connection port. As shown in Fig. 8, the connection port 81 is accessible through an opening in the first decorative cover plate 83. The first decorative cover plate 83 is an optional part and can be attached to the first part 19 of the housing by gluing or otherwise.
[0238] Fig. 9 shows the view of Fig. 8 with the first decorative cover plate 83 removed. Under the first decorative cover plate 83 there is a second optional decorative cover plate 85. The second decorative cover plate 85 can be attached to the first part 19 of the housing by gluing or otherwise.
[0239] Fig. 10 shows the view of Fig. 9 with the second decorative covering plate 85 removed. Under the second decorative covering plate 85, the end surface 87 of the first part 19 of the housing becomes visible.
[0240] Fig. 11 shows a sectional view, and in Fig. 10 the section is designated as III-III. For ease of illustration, Fig. 11 shows only the first part 19 of the housing, the connection port 81, and the two locking members 89, and no other parts are illustrated. In particular, Fig. 11 does not illustrate the various internal parts of the aerosol generating device 3.
[0241] As shown in Fig. 10 and Fig. 11, two fixing elements 89 in the form of screws pass through corresponding fastening holes 91 in the first part 19 of the housing. In particular, the fastening holes 91 are provided on the end surface 87 of the first part 19 of the housing. The fixing elements 89 fix the first part 19 of the housing to the main part 65 of the aerosol generating device 3. The main part 65 is not illustrated in Fig. 11, but is shown in Fig. 12 and Fig. 13. The main part 65 has holes for screws with internal threads for accommodating the fixing elements 89.
[0242] In the illustrated embodiment, there are two locking elements 89, one on each side of the connection port 81. The connection port 81 is accessible through the connector opening 93 on the end surface 87 of the first part 19 of the housing. As can be better seen in Fig. 11, the connection port 81 passes into the connector opening 93 of the first part 19 of the housing. The connection port 81 can pass through the first connector opening 93 of the first part 19 of the housing. An elastomer seal in the form of a sealing element 95, formed by overlay molding on the connection port 81, is in contact with the sealing surface 97 of the first part 19 of the housing. The sealing surface 97 forms and surrounds the connector opening 93. The sealing element 95 is formed by means of overlay molding on the connecting port 81 over the entire circumference of that part of the connecting port 81 which passes into the opening 93 of the connector of the first part 19 of the housing.The sealing element 95 is in contact with the sealing surface 97 of the first part 19 of the housing over the entire circumference of the opening 93 of the connector. The sealing element 95 provides a seal that prevents liquid from entering between the connection port 81 and the first part 19 of the housing. The sealing element 95 is compressed between the first part 19 of the housing and the connection port 81. The sealing element 95 is compressed between the first part 19 of the housing and the sealing surface 97 of the connection port 81 in a direction substantially perpendicular to the axial direction 20.
[0243] Fig. 12 corresponds to the view in Fig. 10 with the first part 19 of the housing removed. Between the main part 65 of the aerosol generating device 3 and the first part 19 of the housing, a separator 99 is provided. In particular, the separator 99 is provided between the main part 65 and the end surface 87 of the first part 19 of the housing. Two fixing elements 89 pass through the openings in the separator 99. The openings in the separator 99 are aligned along the axis with the fastening openings 91 in the first part 19 of the housing.
[0244] Fig. 13 corresponds to the view in Fig. 12 with the separator 99 removed. Between the main part 65 of the aerosol generating device 3 and the separator 99 there is an elastomer sealing layer 101. The fixing elements 89 pass through the openings in the elastomer sealing element 101. The openings in the elastomer sealing element 101 are aligned along the axis with the openings in the separator 99 and with the fastening openings 91 in the first part 19 of the housing. When the locking elements 89 are tightened, the first part 19 of the housing is pressed against the outer surface of the separator 99. In turn, the separator 99 presses on the elastomer sealing layer 101 relative to the main part 65, thereby compressing the elastomer sealing layer 101 between the main part 65 and the first part 19 of the housing. The elastomer sealing layer 101 can form a seal between the main part 65 and the separator 99.The seal may prevent liquid entering through the fastening holes 91 from leaking into the internal compartments of the aerosol generating device 3.
[0245] The separator 99 may be formed from an elastomeric material. When the locking elements 89 are tightened, the separator 99 may be pressed against the first housing portion 19, thereby creating a seal between the first housing portion 19 and the separator 99 at least around the locking elements 89.
[0246] The separator 99 and the elastomeric sealing element 101 may be formed as a single unit. For example, one of the separator 99 and the elastomeric sealing element 101 may be omitted, and the other one of the separator 99 and the elastomeric sealing element 101 may be directly compressed between the main portion 65 and the first housing portion 19.
