[0026] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Please refer to Figures 1 to 7 , an aerosol generating device 100 is provided in an embodiment of this application. The aerosol generating device 100 includes an outer housing 10 and an assembly 20. The interior of the outer housing 10 has a receiving cavity 11 for receiving at least a part of the assembly 20. And ribs 12 are provided on the inner wall of the outer housing 10. The assembly 20 can be slidably connected to the ribs 12, so that the assembly 20 can slide into and out of the receiving cavity 11 relative to the outer housing 10. The assembly 20 includes a first module 21 and a second module 22. One of the first module 21 and the second module 22 includes an atomization core 211, and the atomization core 211 is used for atomizing a liquid matrix to generate an aerosol. The first module 21 includes a first connection portion 212 and a liquid storage cavity 2131, and the liquid storage cavity 2131 is used for storing the liquid matrix. The second module 22 includes a second connection portion 221 and a battery cavity 223. The second connection portion 221 is used for snap-connecting with the first connection portion 212. The battery cavity 223 is used for receiving a power supply assembly 222, and the power supply assembly 222 is used for electrically connecting with the atomization core 211 to supply power to the atomization core 211. When the first module 21 and the second module 22 are docked so that the first connection portion 212 and the second connection portion 221 are snap-connected, the atomization core 211 forms an electrical connection with the power supply assembly 222, and there is a liquid path between the atomization core 211 and the liquid storage cavity 2131 for making the atomization core 211 and the liquid storage cavity 2131 in fluid communication. The liquid matrix in the liquid storage cavity 2131 can flow to the atomization core 211 through this liquid path and thus be heated to form an aerosol. Wherein, at least a part of the assembly 20 is configured to be slidable along the ribs 12 to be received in the receiving cavity 11, and the ribs 12 abut against the first connection portion 212 or the second connection portion 221, so as to prevent the first connection portion 212 or the second connection portion 221 abutted by the ribs 12 from deforming, prevent the first connection portion 212 and the second connection portion 221 from detaching, and ensure the firmness of the connection between the first module 21 and the second module 22.

[0028] With the above structure, the first module 21 and the second module 22 are snap-connected through the first connecting portion 212 and the second connecting portion 221 to form an assembly 20, and then the assembly 20 is assembled into the accommodation cavity 11 of the outer housing 10. Such a modular assembly method greatly improves the assembly efficiency of the aerosol generating device 100. By providing ribs 12 on the inner wall of the outer housing 10, the assembly 20 can be connected to the ribs 12 and slide into the accommodation cavity 11 under the guiding and supporting action of the ribs 12, greatly reducing the difficulty of assembling the assembly 20 with the outer housing 10. In addition, when the assembly 20 is assembled with the outer housing 10 to a preset position, the ribs 12 on the outer housing 10 abut against the first connecting portion 212 or the second connecting portion 221 on the assembly 20 to prevent the first connecting portion 212 or the second connecting portion 221 abutted by the ribs 12 from deforming, ensuring the connection reliability of the modules assembled in the outer housing.

[0029] In some embodiments, please refer to Figures 2 to 4 , the accommodation cavity 11 and the ribs 12 of the outer housing 10 both extend along the first direction X, and the assembly 20 slides into the accommodation cavity 11 along the first direction X. When the assembly 20 slides to the preset assembly position, the ribs 12 abut against the first connecting portion 212 or the second connecting portion 221 in the second direction Y, where the first direction X and the second direction Y are perpendicular to each other. Since the first module 21 and the second module 22 are distributed along the first direction X, and during the buckling process of the first connecting portion 212 and the second connecting portion 221, the first connecting portion 212 or the second connecting portion 221 will deform in the second direction Y, and after the first connecting portion 212 and the second connecting portion 221 are buckled together, the first connecting portion 212 and the second connecting portion 221 remain in mutual interference. During long-term use, it is easy to cause the first connecting portion 212 and / or the second connecting portion 221 to deform, resulting in loose connection between the first module 21 and the second module 22, and further possibly causing unstable electrical connection between the atomization core 211 and the power supply component 222, or causing liquid leakage between the atomization core 211 and the liquid storage cavity 2131.

[0030] Therefore, by providing the ribs 12 to abut against the first connecting portion 212 or the second connecting portion 221 in the second direction Y, the ribs 12 provide support for the first connecting portion 212 and / or the second connecting portion 221, enabling the first connecting portion 212 and the second connecting portion 221 to remain buckled with each other while reducing the interference force between the first connecting portion 212 and the second connecting portion 221, thereby preventing the first connecting portion 212 and the second connecting portion 221 from loosening or even separating due to deformation.

[0031] In some embodiments, please refer to Figure 3 and Figure 4, one of the first connecting portion 212 and the second connecting portion 221 includes a resilient arm 2121 and a hook 2122, the hook 2122 is disposed on the resilient arm 2121, and the other of the two is provided with a stop portion 2211. The stop portion 2211 is located inside the resilient arm 2121, and when the hook 2122 is snap-fitted with the stop portion 2211, the first module 21 and the second module 22 are snap-fitted and fixed. When the assembly 20 formed by the first module 21 and the second module 22 is assembled in the receiving cavity 11 of the outer housing 10, the rib 12 abuts against the outer side of the resilient arm 2121, thereby preventing the resilient arm 2121 from deforming away from the first module 21 or away from the second module 22, resulting in the hook 2122 on the resilient arm 2121 being disengaged from the stop portion 2211.

[0032] In some embodiments, please refer to Figure 6 and Figure 7 , the first module 21 includes a first housing 213, a liquid storage cavity 2131 is formed inside the first housing 213, and the first connecting portion 212 is disposed on the outer wall of the first housing 213. The second module 22 includes a second housing 224, a power supply assembly 222 is disposed in the second housing 224, the second housing 224 defines at least a part of the boundary of the battery cavity 223, and the second connecting portion 221 is disposed on the outer wall of the second housing 224. When the first housing 213 and the second housing 224 are connected along the first direction X, the first connecting portion 212 and the second connecting portion 221 are snap-fitted. In a further embodiment, the first connecting portion 212 is disposed near the end of the first housing 213, and the second connecting portion 221 is disposed near the end of the second housing 224, so that the first connecting portion 212 and the second connecting portion 221 can be more easily snap-fitted, reduce the volume of the first connecting portion 212 and the second connecting portion 221, and thus reduce the overall mass of the aerosol generating device 100.

[0033] It can be understood that the first connecting portion 212 and the second connecting portion 221 can be snap-fitted on one side in the first direction X of the first module 21 and the second module 22, or can be snap-fitted on both sides in the first direction X, which can further increase the firmness of the connection between the first module 21 and the second module 22.

[0034] In some embodiments, please refer to Figure 5, along the second direction Y, the first module 21 has opposite first and second side portions 21a and 21b, and first connecting portions 212 are provided on both the first side portion 21a and the second side portion 21b. Along the second direction Y, the second module 22 has opposite third and fourth side portions 22a and 22b, and second connecting portions 221 are provided on both the third side portion 22a and the fourth side portion 22b; when the first module 21 and the second module 22 are connected along the first direction X, the first connecting portion 212 of the first side portion 21a is snap-connected to the second connecting portion 221 of the third side portion 22a, and the first connecting portion 212 of the second side portion 21b is snap-connected to the second connecting portion 221 of the fourth side portion 22b, and the first direction X is perpendicular to the second direction Y.

[0035] When snap connections of the first connecting portions 212 and the second connecting portions 221 are provided on both sides of the first module 21 and the second module 22, in order to further strengthen the connections of the first connecting portions 212 and the second connecting portions 221 on the left and right sides of the assembly 20, the number of ribs 12 on the inner wall of the outer housing 10 can be set to be multiple, and the positions of the ribs 12 correspond to the positions of the first connecting portions 212 or the second connecting portions 221. Please refer to Figure 2 , on the inner wall of the outer housing 10 in the second direction Y, a first rib 121 and a second rib 122 are respectively provided, and the assembly 20 is respectively slidably connected to the first rib 121 and the second rib 122. When the assembly 20 slides to a preset assembly position, the first rib 121 abuts against the first connecting portion 212 of the first side portion 21a or the second connecting portion 221 of the third side portion 22a, and the second rib 122 abuts against the first connecting portion 212 of the second side portion 21b or the second connecting portion 221 of the fourth side portion 22b.

[0036] In some embodiments, please refer to Figure 6, the first module 21 further includes a sealing plug 214 disposed between the first module 21 and the second module 22 to form a sealed connection between the first module 21 and the second module 22. The sealing plug 214 includes a first sealing portion 2141 and a second sealing portion 2142 oppositely disposed along the first direction X. The first sealing portion 2141 is hermetically connected to the first housing 213 to seal the liquid storage cavity 2131 and prevent the liquid matrix in the liquid storage cavity 2131 from leaking. The second sealing portion 2142 is hermetically connected to the second housing 224 to prevent the liquid matrix in the liquid storage cavity 2131 from leaking into the battery cavity 223 of the second housing 224 and contaminating the power supply assembly 222. In some embodiments, the atomization core 211 is a component of the first module 21, and the atomization core 211 is disposed in the first housing 213 and partially penetrates the liquid storage cavity 2131. At this time, the sealing plug 214 is located between the atomization core 211 and the power supply assembly 222. A gas guiding through hole 2143 is formed in the sealing plug 214. An air intake passage 2241 communicating with the outside is provided in the second housing 224. The gas guiding through hole 2143 communicates the atomization core 211 and the air intake passage 2241, so that other substances in the outside can enter the atomization core 211 from the air intake passage 2241 through the gas guiding through hole 2143. It can be understood that in other embodiments, the atomization core 211 can be a component of the second module 22, and the atomization core 211 is disposed in the second housing 224. At this time, the atomization core 211 is located between the sealing plug 214 and the power supply assembly 222. The atomization core 211 penetrates the sealing plug 214. The liquid path portion connecting the atomization core 211 and the liquid storage cavity 2131 is partially formed in the first module 21 and partially formed in the second module 22. When the first module 21 and the second module 22 are snap-connected, these two parts of the liquid path are connected to form a complete liquid path, so that the liquid matrix in the liquid storage cavity 2131 can flow to the atomization core 211 through the complete liquid path.

[0037] The first module 21 and the second module 22 share a sealing plug 214, which can not only reduce costs but also help reduce the volume of the aerosol generating device.

[0038] In some embodiments, please refer to Figure 7, a first air inlet hole 13 communicating with the outside is formed on the outer housing 10. The power supply assembly 222 includes a battery cell 2221. The second housing 224 includes a bottom plate 2242 for supporting the battery cell 2221. A second air inlet hole 22421 is formed on the bottom plate 2242. The second air inlet hole 22421 is in fluid communication with the first air inlet hole 13 and the air inlet passage 2241. The outside air can sequentially pass through the first air inlet hole 13, the second air inlet hole 22421, the air inlet passage 2241 and the air guiding through hole 2143 to reach the inside of the atomization core 211. It can be understood that the power supply assembly 222 may further include a circuit board 2222. The circuit board 2222 is disposed inside the first housing 213 or inside the second housing 224. The circuit board 2222 forms an electrical connection with the battery cell 2221 and the atomization core 211, so as to control the battery cell 2221 to work for the atomization core 211.

[0039] In some embodiments, please refer to Figure 3 , a sliding groove 23 is provided on the assembly 20. The sliding groove 23 is used for sliding connection with the rib 12 to guide the first connecting portion 212 and the second connecting portion 221 to be abutted by the rib 12. Specifically, the sliding groove 23 may be provided on the outer wall of the first housing 213 and extend along the first direction X. After the first housing 213 and the second housing 224 are snap-connected to form the assembly 20, when the assembly 20 is assembled with the outer housing 10, the first housing 213 enters the accommodation cavity 11 before the second housing 224. Therefore, the sliding groove 23 is provided on the first housing 213, which can facilitate the assembly 20 to be quickly and directionally assembled with the outer housing 10 and improve the assembly efficiency.

[0040] In some embodiments, please refer to Figure 1 , the outer housing 10 includes a first outer housing 14 and a second outer housing 15. The first outer housing 14 and the second outer housing 15 respectively define partial boundaries of the accommodation cavity 11. When the first outer housing 14 and the second outer housing 15 are connected, they jointly enclose to form the accommodation cavity 11. One end of the first outer housing 14 is provided with a mouthpiece 141. The mouthpiece 141 communicates the accommodation cavity 11 with the outside. The other end of the first outer housing 14 opposite in the first direction X is an assembly end 142. The assembly 20 enters the inside of the first outer housing 14 through the assembly end 142, so that the aerosol generated by the atomization core 211 can be discharged from the mouthpiece 141 for the user to suck. The second outer housing 15 is connected to the assembly end 142 of the first outer housing 14, so as to hold the assembly 20 in the accommodation cavity 11.

[0041] In some embodiments, please refer to Figure 1, the accommodation depth of the accommodation cavity 11 in the first outer housing 14 is greater than that of the accommodation cavity 11 in the second outer housing 15, and the rib 12 is provided on the inner wall of the first outer housing 14. By setting the accommodation cavity 11 of the first outer housing 14 deeper, most of the volume of the assembly 20 can be accommodated in the first outer housing 14, facilitating the assembly of the assembly 20 and the first outer housing 14. And by providing the rib 12 on the inner wall of the first outer housing 14, the assembly 20 can be more easily slidably connected during the assembly with the first outer housing 14.
