[0045] Such as Figures 1 to 8As shown in the figure, the aerosol generating device provided by the embodiment of the present application includes a first housing 10, a second housing 20, an atomization assembly 30, an electrical assembly 40, and a pushing assembly 50. The first housing 10 is formed with a mouthpiece 11. The second housing 20 is covered with the first housing 10. The second housing 20 is provided with an air flow channel 21. The bottom wall of the second housing 20 has an assembly hole 22. The atomization assembly 30 has an air inlet end 321 and an air outlet end 322. The atomization assembly 30 is installed in the first housing 10. The air inlet of the air inlet end 321 is communicated with the air flow channel 21, and the air outlet of the air outlet end 322 is communicated with the mouthpiece 11. The electrical assembly 40 includes a bracket 41, a PCB board 42, and a shrapnel 43. As Figure 8 shown, the PCB board 42 has a first pole 421 and a second pole 422. The bracket 41 is installed in the second housing 20. As Figures 4 to 6 shown, the PCB board 42 is snap-fixed to the bracket 41 through the buckle ear 414 of the bracket 41 and is located at one end of the bracket 41 away from the first housing 10. One end of the shrapnel 43 is electrically connected to the first pole 421, and the other end of the shrapnel 43 extends towards the second pole 422. The atomization assembly 30 is electrically connected to the PCB board 42. The pushing assembly 50 includes a push rod 51 and an elastic member 52. The push rod 51 has a pushing protrusion 511. The push rod 51 is slidably connected to the bracket 41. The protrusion is located on the side of the PCB board 42 away from the bracket 41. The elastic member 52 is pre-tensioned and installed between the push rod 51 and the bottom wall of the second housing 20. One end of the push rod 51 away from the first housing 10 has a stop protrusion 512. When the push rod 51 is inserted into the assembly hole 22 and the stop protrusion 512 is hooked on the edge area 23 of the orifice of the assembly hole 22, the elastic member 52 is compressed by the push rod 51, and the other end of the shrapnel 43 is disconnected from the second pole 422; when the stop protrusion 512 is unhooked from the edge area 23 of the orifice of the assembly hole 22, the push rod 51 slides under the elastic force of the elastic member 52, and the pushing protrusion 511 pushes the other end of the shrapnel 43 to be electrically connected to the second pole 422, so that the atomization assembly 30 is turned on.

[0046] In the aerosol generating device provided in the present application, the first pole 421 and the second pole 422 of the PCB board 42 are electrically connected through the elastic sheet 43, and then the atomization assembly 30 is turned on. Before the aerosol generating device is used by the user, the push rod 51 is in a state of being inserted into the assembly hole 22 and the stop projection 512 is hooked on the edge area 23 of the orifice of the assembly hole 22. At this time, the elastic member 52 is compressed by the push rod 51, and the other end of the elastic sheet 43 is disconnected from the second pole 422, that is, both the PCB board 42 and the atomization assembly 30 are in a disconnected state. Therefore, even under the condition of air flow, the aerosol generating device will not start automatically, and the PCB board 42 is in a disconnected and non-electrified state, thereby reducing the probability of the PCB board 42 being short-circuited and causing damage to the function of the aerosol generating device. When the aerosol generating device is purchased by the user and needs to be used, the stop projection 512 is disengaged from the edge area 23 of the orifice of the assembly hole 22, the push rod 51 slides under the elastic force of the elastic member 52, and the top projection 511 pushes the other end of the elastic sheet 43 to be electrically connected to the second pole 422, so as to turn on the atomization assembly 30. At this time, the user inhales through the mouthpiece 11, and the air flow passes through the atomization assembly 30, thereby starting to generate aerosol for the user to inhale.

[0047] Preferably, the elastic member 52 is a helical spring, and the helical spring is always pre-compressed between the push rod 51 and the bottom wall of the second housing 20.

[0048] As Figures 1 to 5 shown, the aerosol generating device further includes a locking structure 60, and the locking structure 60 is detachably connected to the second housing 20. Moreover, the locking structure 60 is detachably connected to the push rod 51 to restrict the stop projection 512 from disengaging from the edge area 23 of the orifice of the assembly hole 22. In this way, by locking the push rod 51 and the second housing 20 through the locking structure 60, the stop projection 512 of the push rod 51 will not disengage from the edge area 23 of the orifice of the assembly hole 22 during the transportation of the aerosol generating device, so that the push rod 51 is always locked with the second housing 20, and the push rod 51 will not be slid by the elastic force of the elastic member 52 to push the elastic sheet 43.

[0049] In the aerosol generating device provided in the embodiment of the present application, as Figure 4 and Figure 5 shown, the locking structure 60 includes a bottom patch 61, and the bottom patch 61 includes a patch body 611 and a convex block 612 provided on the patch body 611. As Figure 5 and Figure 7As shown, one end of the push rod 51 away from the first shell 10 is provided with two elastic arms 513 that are opposite and spaced apart. A coil spring covers the two elastic arms and pushes against the push protrusion 511. The elastic arms 513 are provided with stop protrusions 512, and the stop protrusions 512 of the two elastic arms 513 face each other. When the push rod 51 is locked with the second shell 20 by the locking structure 60, the bottom patch 61 is attached to the outer side of the bottom wall of the second shell 20, the two elastic arms 513 are inserted into the assembly hole 22, and the protrusion 612 is inserted between the two elastic arms 513. The protrusion 612 causes the two elastic arms 513 to be stretched apart, thereby limiting the orifice edge area 23 of the two stop protrusions 512 from being hooked off the assembly hole 22. When the aerosol generating device is purchased by a user and needs to be used, the user only needs to remove the bottom patch 61 from the outer side of the bottom wall of the second shell 20, that is, the protrusion 612 is separated from the two elastic arms 513, as shown in FIG. Figure 6 and Figure 7 As shown, the two elastic arms 513 approach each other under their own elastic force, and then the two stop protrusions 512 are both unhooked from the hole edge area 23 of the assembly hole 22, and the push rod 51 slides under the elastic force of the elastic member 52, and the other end of the push protrusion 511 pushes the spring sheet 43 to be electrically connected to the second pole 422, so that the atomizer assembly 30 is turned on. At this time, the user inhales through the mouthpiece 11, and the airflow flows through the atomizer assembly 30, thereby starting to generate aerosol for the user to inhale.

[0050] Further, such as Figure 4 and Figure 5 As shown, the locking structure 60 of the aerosol generating device also includes an auxiliary patch 62, which is a double-sided adhesive patch. The patch body 611 of the bottom patch 61 is attached to the outer side of the bottom wall of the second shell 20 through the auxiliary patch 62, and the protrusion 612 passes through the auxiliary patch 62 from the through hole 622 of the auxiliary patch 62 and is inserted between the two elastic arms 513. In this way, the patch body 611 of the bottom patch 61 is adhered by the auxiliary patch 62, so that the patch body 611 is not easy to tilt up, and the patch body 611 is effectively prevented from being detached from the bottom wall of the second shell 20 due to misoperation when tilting up. In addition, the auxiliary patch 62 has a pull ear 621 extending from the bottom patch 61, and the user can easily remove the auxiliary patch 62 from the bottom wall of the second shell 20 through the pull ear 621, and at the same time, the bottom patch 61 is separated from the bottom wall of the second shell 20.

[0051] like Figures 4 to 7As shown, in the aerosol generating device provided by the embodiment of the present application, the atomization assembly 30 includes a sealing member 31 and an atomizing device 32. The atomizing device 32 is electrically connected to the PCB board 42. The atomizing device 32 has an air inlet end 321, an air outlet end 322, and a liquid inlet hole 323 located between the air inlet end 321 and the air outlet end 322. Specifically, the sealing member 31 is sleeved on the atomizing device 32. The atomizing device 32 can slide relative to the sealing member 31. The sealing member 31 is installed in the opening end 12 of the first housing 10. The air outlet end 322 is slidably inserted into the mouthpiece 11. A first seal 91 is provided for sealing between the circumferential side wall of the air outlet end 322 and the inner wall of the mouthpiece 11. In this way, the sealing member 31, a part of the atomizing device 32 located between the sealing member 31 and the mouthpiece 11, and the first housing 10 form a liquid storage cavity 13. And, the first housing 10 is provided with a liquid injection hole 14. The liquid aerosol generating matrix is filled into the liquid storage cavity 13 through the liquid injection hole 14, and then the liquid injection hole 14 is sealed by a plug 94. As Figures 5 to 7 As shown, the push rod 51 is slidably inserted through the bracket 41. When the stop projection 512 is hooked on the edge area 23 of the orifice of the assembly hole 22, the liquid inlet hole 323 is sealed by the sealing member 31. That is, during the transportation of the aerosol generating device, even in the case of bumps, the liquid aerosol generating matrix in the liquid storage cavity 13 cannot enter the atomizing device 32 from the liquid inlet hole 323, thereby preventing the leakage of the liquid aerosol generating matrix. When the stop projection 512 disengages from the edge area 23 of the orifice of the assembly hole 22, the end of the push rod 51 facing the first housing 10 pushes the atomizing device 32 to slide, so that the liquid inlet hole 323 communicates with the liquid storage cavity 13. Thus, the liquid aerosol generating matrix can enter the atomizing device 32 from the liquid inlet hole 323. And, the top projection 511 pushes the other end of the elastic piece 43 to be electrically connected to the second pole 422 to turn on the atomization assembly 30. The user inhales through the mouthpiece 11, and the air flow passes through the atomization assembly 30, thereby starting to generate aerosol for the user to inhale.

[0052] As Figures 4 to 7 As shown, a baffle 312 is attached to one end of the sealing member 31 facing the liquid storage cavity 13, so as to prevent the liquid aerosol generating matrix from contacting the sealing member 31 through the baffle 312, thereby protecting the sealing member 31 from being impregnated and eroded by the liquid aerosol generating matrix. And, when the stop projection 512 disengages from the edge area 23 of the orifice of the assembly hole 22, the push rod 51 pushes the atomizing device 32 to slide relative to the sealing member 31, so that the liquid inlet hole 323 is higher than the baffle 312. At this time, the liquid inlet hole 323 communicates with the liquid storage cavity 13.

[0053] As Figures 5 to 7As shown, one end of the bracket 41 facing the first housing 10 is formed with a circumferential baffle 411. The circumferential baffle 411 surrounds the air inlet end 321. The circumferential baffle 411 abuts against the sealing member 31, and a sealing arrangement is provided between the circumferential baffle 411 and the sealing member 31. Specifically, an embedding groove 311 is formed at one end of the sealing member 31 facing the second housing 20. The circumferential baffle 411 is inserted into the embedding groove 311. Since the sealing member 31 is integrally formed of silica gel material and the sealing member 31 itself has elastic deformation performance, the sealing member 31 can form a sealing fit with the circumferential baffle 411 inserted into the embedding groove 311. In this way, the air inlet end 321 is located in the sealed space surrounded by the circumferential baffle 411. When the liquid aerosol generating matrix flows down along the atomizing device 32 and flows out from the air inlet of the air inlet end 321, the aerosol generating matrix will flow into the sealed space surrounded by the circumferential baffle 411 and be temporarily stored, rather than directly leaking to the outside of the aerosol generating device.

[0054] As Figures 5 to 7 shown, the bracket 41 is further formed with a first groove 412. The circumferential baffle 411 surrounds the first groove 412. The air inlet end 321 is slidably inserted into the first groove 412, and a sealing arrangement is provided between the circumferential side wall of the air inlet end 321 and the groove wall of the first groove 412 through a second seal 92. One end of the push rod 51 facing the first housing 10 passes through the avoidance hole 424 of the PCB board 42 and extends into the first groove 412. When the stop projection 512 disengages from the edge region 23 of the orifice of the mating hole 22 of the hook, the push rod 51 slides under the elastic force of the elastic member 52. One end of the push rod 51 extending into the first groove 412 pushes the atomizing device 32 so that the liquid inlet hole 323 communicates with the liquid storage cavity 13. That is to say, the first groove 412 can perform sliding positioning on the sliding process of the atomizing device 32, so that the atomizing device 32 will not be deflected during the sliding process and the atomizing device 32 can slide stably. Moreover, the top projection 511 pushes the other end of the elastic sheet 43 to be electrically connected to the second pole 422 to turn on the atomizing assembly 30. At this time, the user inhales through the mouthpiece 11, and the air flow passes through the atomizing assembly 30, thereby starting to generate aerosol for the user to inhale.

[0055] To further prevent the liquid aerosol generating matrix entering the sealed space surrounded by the circumferential baffle 411 from leaking to the outside of the aerosol generating device, therefore, as Figures 4 to 7As shown, the aerosol generating device further includes a liquid absorbing cotton 70 and a guiding structure 80. Specifically, the bracket 41 further forms a second groove 413, and the second groove 413 surrounds the first groove 412. The liquid absorbing cotton 70 is disposed in the second groove 413. In this way, the liquid aerosol generating matrix entering the sealed space surrounded by the circumferential baffle 411 will be absorbed by the liquid absorbing cotton 70, so that the liquid aerosol generating matrix will not leak to the outside of the aerosol generating device. And, the guiding structure 80 is installed on the bracket 41, and the circumferential baffle 411 surrounds the second groove 413 and the air outlet of the guiding structure 80. The air outlet of the guiding structure 80 is higher than the liquid absorbing cotton 70. Therefore, the liquid aerosol generating matrix flowing out from the air inlet end 321 will not flow to the air outlet of the guiding structure 80. The air outlet of the guiding structure 80 is communicated with the air inlet of the air inlet end 321, and the air inlet of the guiding structure 80 is communicated with the air flow channel 21.

[0056] As Figure 4 shown, the guiding structure 80 includes a guiding tube 81 and a flexible guiding sleeve 82. The guiding sleeve 82 is sleeved on the guiding tube 81. The guiding sleeve 82 is integrally formed of silica gel material. The guiding sleeve 82 is clamped in the bracket 41. The PCB board 42 is provided with a ventilation hole 423. As Figure 8 shown, the guiding sleeve 82 abuts against the PCB board 42, thereby preventing the guiding tube 81 from directly and rigidly contacting and abutting against the PCB board 42, effectively protecting the PCB board 42. The guiding tube 81 is communicated with the ventilation hole 423, and moreover, the air flow channel 21 is communicated with the ventilation hole 423.

[0057] In order to better protect the PCB board 42, therefore, as Figure 4 and Figure 7 shown, the aerosol generating device further includes a buffer member 90. The buffer member 90 is disposed on the PCB board 42, and moreover, the end surface of the air outlet of the air flow channel 21 abuts against the buffer member 90. That is to say, the buffer member 90 can prevent the end surface of the air outlet of the air flow channel 21 from directly and rigidly contacting and abutting against the PCB board 42, effectively protecting the PCB board 42. Specifically, the buffer member 90 can be formed by using buffer foam (at this time, the sealing effect between the buffer member 90 on the PCB board 42 and the end surface of the air outlet of the air flow channel 21 is general, and the buffer member 90 made of buffer foam focuses on buffering and abutting the end surface of the air outlet of the air flow channel 21 against the PCB board 42), or can be formed by using silica gel (at this time, the buffer member 90 can not only buffer and abut the end surface of the air outlet of the air flow channel 21 against the PCB board 42, but also seal between the PCB board 42 and the end surface of the air outlet of the air flow channel 21).

[0058] In the aerosol generating device of the present application, as Figure 7 shown, the first housing 10 and the second housing 20 are covered with each other to form a battery compartment 15. As Figure 4 and Figure 7As shown, the electrical component 40 further includes a battery 44. The battery 44 is installed in the battery compartment 15. And a support silica gel 442 is provided between the battery 44 and the first housing 10, and a battery foam 441 is provided between the battery 44 and the second housing 20. The battery foam 441 and the support silica gel 442 are both deformed by the extrusion of the battery 44, so as to ensure that the battery 44 is stably assembled without loosening. The battery 44 is electrically connected to the PCB board 42, and the battery 44 provides the required electrical energy.

[0059] In order to make the appearance of the mutually covered first housing 10 and second housing 20 more beautiful, therefore, as Figures 1 to 7 shown, a decorative sticker 93 is attached to the surfaces of the first housing 10 and the second housing 20, and decorative patterns and the like can be printed on the decorative sticker 93.

[0060] Moreover, before the user uses the aerosol generating device to inhale the aerosol, the mouthpiece 11 is covered with a mouthpiece silica gel 95, so as to prevent dust, sundries, etc. from entering the interior of the aerosol generating device and ensure the cleanliness of the interior of the aerosol generating device. When the user uses the aerosol generating device to inhale the aerosol, the user can remove the mouthpiece silica gel 95 from the mouthpiece 11.

[0061] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
