[0035] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device includes a power supply component 100 and an atomizer 200. The power supply component 100 is used to supply power to the atomizer 200.

[0036] Figure 2 This is an exploded structural diagram of an atomizer provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 200 includes a housing assembly 230, a liquid reservoir assembly 210, and an atomizing assembly 220. The housing assembly 230 includes a housing structure 240 and a nozzle 250, with the nozzle 250 mounted on the housing structure 240. The liquid reservoir assembly 210 is located within the housing assembly 230 and is used to store the aerosol matrix. The atomizing assembly 220 is located within the liquid reservoir assembly 210 and is used to heat the aerosol matrix; the atomizing assembly 220 has an atomization channel 220a.

[0037] The liquid storage assembly 210 may include a liquid reservoir housing 211, the interior of which forms a liquid reservoir for containing the aerosol matrix. In some examples, the liquid storage assembly 210 may also include a liquid storage element 212, such as a liquid storage cotton that has been adsorbed / wetted with the aerosol matrix.

[0038] The atomizing component 220 is located in the liquid tank housing 211. Figure 3 This is a schematic diagram of the internal structure of a liquid storage device provided in an embodiment of this application. For example... Figure 3 As shown, the atomizing assembly 220 can be located in the liquid storage container 212. The atomizing assembly 220 includes a support 221, a liquid guide 222, and a heating element 223. The support 221 forms an atomizing channel 220a, and the liquid guide 222 and the heating element 223 are located in the support 221. The material and structure of the heating element 223 are not limited, as long as it can generate heat. For example, the heating element 223 may include at least one of a heating mesh, a heating film, a heating wire, and a heating plate.

[0039] The support 221 provides space inside the liquid tank housing 211 to accommodate the liquid guiding component 222 and the heating component 223. The support 221 may be tubular, and its wall may have structures such as holes and slits to allow the aerosol matrix in the liquid tank housing 211 to enter the atomization channel 220a and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol matrix in the liquid guiding component 222, causing the aerosol matrix to vaporize.

[0040] The liquid tank shell 211 has an opening at one end facing the outlet of the atomization channel 220a, and the aerosol matrix heated and vaporized by the heating element 223 can be discharged outward through the through hole 211a.

[0041] The heating element 223 may be connected to an electrode, which is exposed outside the liquid tank housing 211. The power supply assembly 100 may have a power supply terminal that can make electrical contact with the electrode exposed outside the liquid tank housing 211, thereby supplying power to the atomizer 200.

[0042] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Because the power supply assembly 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0043] In other examples, the power supply assembly 100 and the atomizer 200 can be fixedly connected. For example, the housing portion of the power supply assembly 100 and the liquid tank housing 211 of the atomizer 200 are integrally formed, or the housing portion of the power supply assembly 100 and the housing structure 240 are integrally formed.

[0044] In related technologies, the mouthpiece 250 is installed on the housing structure 240 of the atomizer 200 via a snap-fit ​​structure. In the scenario where the aerosol generating device is dropped, the snap-fit ​​structure has a relatively high risk of breakage and failure, which could cause the mouthpiece to fall off.

[0045] Figure 4 This is a schematic diagram of the structure of a housing assembly provided in an embodiment of this application. Figure 4 As shown, the housing assembly 230 includes a housing structure 240 and a suction nozzle 250, wherein the housing structure 240 includes an outer housing 241 and an inner housing 242.

[0046] The outer shell 241 has a first opening 241a, the inner shell 242 has a second opening 242a, the outer shell 241 is fitted over the inner shell 242, the suction nozzle 250 is located at the second opening 242a and communicates with the second opening 242a, the suction nozzle 250 is inserted into the first opening 241a, and part of the suction nozzle 250 is sandwiched between the inner shell 242 and the outer shell 241.

[0047] By configuring the housing structure 240 as an outer housing 241 and an inner housing 242, with the outer housing 241 fitted over the inner housing 242, and the nozzle 250 positioned at the second opening 242a of the inner housing 242, the nozzle 250 communicates with the second opening 242a. By inserting the nozzle 250 into the first opening 241a of the outer housing 241, a portion of the nozzle 250 is clamped between the inner housing 242 and the outer housing 241. The clamping action of the outer housing 241 and the inner housing 242 restricts the nozzle 250, ensuring its secure installation on both the inner and outer housings. Since the nozzle 250 is not fixed by a snap-fit ​​structure, the risk of the aerosol generator falling off due to snap-fit ​​structure failure during a drop is reduced.

[0048] In some examples, the liquid tank housing 211 and the inner housing 242 in the atomizer 200 can also be the same structural component, that is, the inner housing 242 can be reused as the liquid tank housing 211, so as to reduce the number of parts in the atomizer 200 and make the structure of the atomizer 200 more compact.

[0049] like Figure 4 As shown, the nozzle 250 includes a nozzle body 251 and a mounting plate 252, with one end of the nozzle body 251 connected to one side of the mounting plate 252. The nozzle body 251 is inserted into the first opening 241a, and the mounting plate 252 is sandwiched between the inner shell 242 and the outer shell 241.

[0050] The nozzle body 251 is exposed outside the outer shell 241 through the first opening 241a, allowing the user to put it into their mouth during use. The mounting plate 252 is sandwiched between the inner shell 242 and the outer shell 241, so that the nozzle 250 can be firmly and stably mounted on the shell structure 240.

[0051] The nozzle body 251 and the mounting plate 252 can be made of different materials. When the nozzle 250 is molded using a two-color injection molding process, the nozzle body 251 can be injection molded using one material, and the mounting plate 252 can be injection molded using another material.

[0052] like Figure 4 As shown, the outer surface of the inner shell 242 has a recessed region 242b, and the mounting plate 252 is located in the recessed region 242b.

[0053] When the outer shell 241 and the inner shell 242 are assembled together, the mounting plate 252 is confined within the recessed area 242b, making the nozzle 250 more secure. Furthermore, the recessed area 242b also facilitates a better fit between the inner shell 242 and the outer shell 241, resulting in a more compact and robust structure for the shell assembly 230.

[0054] As an example, the surface of the mounting plate 252 may be flush with the surface outside the recessed area 242b of the inner housing 242.

[0055] In other words, the depth of the recessed area 242b is consistent with the thickness of the mounting plate 252. This makes the transition between the mounting plate 252 and the outer surface of the inner shell 242 smoother when the mounting plate 252 is assembled to the inner shell 242, allowing the surface of the inner shell 242 to be closer to the outer shell 241, thereby clamping the mounting plate 252 more stably.

[0056] In some examples, the mounting plate 252 is snapped into the inner housing 242.

[0057] By snapping the mounting plate 252 to the inner shell 242, the assembly of the shell assembly 230 can be facilitated. When assembling the shell assembly 230, the mounting plate 252 of the nozzle 250 can be connected to the inner shell 242 first, so that the nozzle 250 and the inner shell 242 are assembled as one unit. Then, the outer shell 241 is put over the inner shell 242, so that the nozzle body 251 passes through the first opening 241a of the outer shell 241.

[0058] As an example, Figure 5 This is a schematic diagram of the structure of a suction nozzle provided in an embodiment of this application. Figure 5As shown, the mounting plate 252 has a first latch 2521 and a second latch 2522 on the side away from the nozzle body 251, and the nozzle body 251 is located between the first latch 2521 and the second latch 2522. Figure 6 This is a schematic diagram of the internal structure of a housing assembly provided in an embodiment of this application. For example... Figure 6 As shown, the first buckle 2521 and the second buckle 2522 are respectively engaged with the inner shell 242.

[0059] The phrase "the nozzle body 251 is located between the first buckle 2521 and the second buckle 2522" means that in the arrangement direction of the nozzle body 251, the first buckle 2521 and the second buckle 2522, the nozzle body 251 is located between the first buckle 2521 and the second buckle 2522, and it does not mean that the three are located on the same side of the mounting plate 252.

[0060] By providing a first latch 2521 and a second latch 2522 on the side of the mounting plate 252 away from the nozzle body 251, and in the arrangement direction, the first latch 2521 and the second latch 2522 are located on opposite sides of the nozzle body 251, so that the nozzle 250 can be more stably assembled to the inner shell 242, and the nozzle 250 is prevented from becoming loose during the assembly of the outer shell 241, thus affecting the assembly of the shell assembly 230.

[0061] As an example, the first snap fastener 2521 may be located in the second opening 242a of the inner housing 242 and engage with the edge of the second opening 242a. A locking hole 242c may be provided on one side of the second opening 242a of the inner housing 242, and the second snap fastener 2522 may engage with this locking hole 242c.

[0062] like Figure 6 As shown, the mounting plate 252 has a positioning retaining ring 2523 on the side away from the nozzle body 251, and the positioning retaining ring 2523 is located in the second opening 242a. The positioning retaining ring 2523 is in transition fit with the second opening 242a.

[0063] Among them, transition fit can be either clearance fit or interference fit.

[0064] By setting a positioning retaining ring 2523 to cooperate with the second opening 242a, the positioning retaining ring 2523 can play a positioning role when assembling the suction nozzle 250 and the inner shell 242, making the connection between the suction nozzle 250 and the inner shell 242 more stable, which is conducive to improving the assembly accuracy and facilitating the assembly of the outer shell 241.

[0065] like Figure 4 As shown, the outer side wall of the nozzle body 251 near the mounting plate 252 has a flange 2511. (As indicated...) Figure 6As shown, flange 2511 is located in the first opening 241a and transitionally engages with the first opening 241a.

[0066] After inserting the nozzle body 251 into the first opening 241a of the outer shell 241, the flange 2511 forms a fit with the first opening 241a, which helps to further improve the installation accuracy of the nozzle 250 and prevent the nozzle 250 from becoming loose.

[0067] In some examples, the outer housing 241 and the inner housing 242 can snap together. For example... Figure 6 As shown, the inner shell 242 may have a third buckle 2421 on the side wall at the end away from the nozzle 250, and the inner side wall of the outer shell 241 may have a slot 241b, in which the third buckle 2421 is engaged.

[0068] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
