[0036] Referring to Figures 1, 2, 3 and 4, an aerosol generating device 30 provided in an embodiment of the present application includes an aerosol generating device 20 and a host 10, wherein the aerosol generating device 20 and the host 10 are detachably connected, or the aerosol generating device 20 and the host 10 are non-detachably connected, the host 10 includes a battery 12 and a housing 11, the battery 12 is located in the housing 11, the aerosol generating device 20 can be inserted in the housing 11, so that the aerosol generating device 20 can slide relative to the housing 11, the housing 11 is provided with a receiving cavity 111, the battery 12 is received in the receiving cavity 111, and the side of the receiving cavity 111 away from the aerosol generating device 20 can be connected to the outside. The aerosol generating device 20 includes a housing assembly 200, an atomizing assembly 300, a base assembly 400 and a conductive assembly 500. The base assembly 400 can slide relative to both the atomizing assembly 300 and the housing assembly 200, and the conductive assembly is electrically connected to the battery 12.

[0037] Referring to FIG. 1 , FIG. 2 and FIG. 3 , in some embodiments, the housing assembly 200 includes a liquid storage shell 210, a nozzle rod 220 and a sealing member 230. A liquid storage chamber 211 is provided in the housing assembly 200, and the liquid storage chamber 211 is used to accommodate a liquid atomization medium. The liquid storage shell 210, the nozzle rod 220, the sealing member 230 and the atomization assembly 300 can together enclose the liquid storage chamber 211. The nozzle rod 220 can be integrally formed with the liquid storage shell 210, and the liquid storage shell 210 has a first end and a second end opposite to each other. The nozzle rod 220 is located in the liquid storage shell 210 and connected to the first end of the liquid storage shell 210, and the nozzle rod 220 extends a certain length toward the second end. An air suction channel 2221 is provided in the nozzle rod 220, and the end of the air suction channel 2221 close to the first end of the liquid storage shell 210 is connected to the outside world, and the user can inhale the aerosol at the end of the air suction channel 2221.

[0038] Referring to Fig. 1, Fig. 2 and Fig. 3, the liquid storage shell 210 may be provided with a first limiting hole 213 and a second limiting hole 214, which are spaced apart along the axial direction of the liquid storage shell 210, and are both used to cooperate with the base assembly 400. When the base assembly 400 slides relative to the liquid storage shell 210, the base assembly 400 can cooperate with the first limiting hole 213 and the second limiting hole 214 at different positions. The inner wall surface of the liquid storage shell 210 may also be recessed to form a guide groove 212, which is slidably matched with the base assembly 400, so that the sliding accuracy of the base assembly 400 relative to the liquid storage shell 210 can be improved.

[0039] Referring to Fig. 1, Fig. 2 and Fig. 3, the seal 230 can be made of a flexible material, for example, the seal 230 can be made of a material such as silica gel, and the seal 230 can be fixedly arranged in the liquid storage shell 210, so that the seal 230 and the liquid storage shell 210 can move synchronously, and the seal 230 can play a good sealing role on the liquid storage chamber 211. The seal 230 is sleeved on the atomization assembly 300, and the seal 230 can slide relative to the atomization assembly 300. The housing assembly 200 can also include a reinforcement 240, and the reinforcement 240 can be made of a stainless steel material, so that the rigidity of the reinforcement 240 is greater than the rigidity of the seal 230. The reinforcing member 240 may be roughly annular, and the reinforcing member 240 is embedded in the sealing member 230. By providing the reinforcing member 240, the rigidity and strength of the sealing member 230 can be reasonably improved, and the sealing member 230 is prevented from being greatly deformed during the sliding process relative to the atomizing assembly 300, thereby improving the sealing performance of the sealing member 230 to the liquid storage chamber 211. A guide hole 232 may be opened in the sealing member 230, and the guide hole 232 is slidably matched with the base assembly 400.

[0040] Referring to Fig. 2, Fig. 3 and Fig. 7, a guide surface 231 is provided on the side of the seal 230 facing the liquid storage chamber 211, and the guide surface 231 is an inclined surface, so that the guide surface 231 is arranged at an angle relative to the axial direction of the liquid storage shell 210, and the guide surface 231 is inclined from the side away from the assembly toward the side close to the atomizing assembly 300. By providing the guide surface 231, a good guiding effect can be played on the atomizing medium in the liquid storage chamber 211, so that the atomizing medium can smoothly enter the atomizing assembly 300. The end of the seal 230 away from the liquid storage chamber 211 is spaced from the atomizing assembly 300, so that an annular gap 233 is formed between the seal 230 and the atomizing assembly 300.

[0041] Referring to FIGS. 2, 3, 4 and 6, in some embodiments, the atomizer assembly 300 includes an atomizer seat 310 and an atomizer core 320. The atomizer seat 310 includes a body portion 330 and a boss 340, and the boss 340 protrudes from the side of the body portion 330. The body portion 330 may include a bottom plate 331 and a side tube 332, the side tube 332 is arranged around the edge of the bottom plate 331, the boss 340 may be arranged on the side tube 332 along the radial direction of the side tube 332, the side tube 332 surrounds the atomization channel 3321, the atomizer core 320 is located in the atomization channel 3321, and the side tube 332 is provided with a liquid inlet hole 3323 and an air inlet hole 3322, the liquid inlet hole 3323 and the air inlet hole 3322 are spaced a certain distance along the axial direction of the side tube 332, and the liquid inlet hole 3323 can connect the atomization channel 3321 and the liquid storage chamber 211. The atomizing core 320 can cover the liquid inlet hole 3323. For example, the atomizing core 320 can block one end of the liquid inlet hole 3323 connected to the atomizing channel 3321. When the atomizing medium flows from the liquid storage chamber 211 into the liquid inlet hole 3323, the atomizing medium in the liquid inlet hole 3323 will contact the atomizing core 320 and penetrate into the atomizing core 320. The atomizing core 320 can generate heat, so that the atomizing medium that penetrates into the inside of the atomizing core 320 absorbs heat and atomizes to form an aerosol. The nozzle rod 220 can be inserted into the atomizing channel 3321, and the nozzle rod 220 is sealed and connected to the atomizing seat 310, so the nozzle rod 220 can play a good sealing role on the atomizing channel 3321, and the nozzle rod 220 can slide in the atomizing channel 3321 relative to the atomizing seat 310. The inhalation channel 2221 of the nozzle rod 220 is connected to the atomization channel 3321. When the user inhales at the end of the inhalation channel 2221, the aerosol in the atomization channel 3321 can enter the inhalation channel 2221 to be absorbed by the user. The air inlet 3322 is arranged on the side tube 332, so the air inlet 3322 is arranged on the side of the atomization seat 310. The air inlet 3322 can maintain a certain distance from the bottom plate 331 along the axial direction of the side tube 332. When the user inhales, the gas can enter the atomization channel 3321 from the air inlet 3322 to carry the aerosol into the inhalation channel 2221.

[0042] Referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 6, a ventilation groove 3324 is further provided on the side tube 332, and the ventilation groove 3324 can be connected to the liquid inlet hole 3323. When the liquid inlet hole 3323 is connected to the liquid storage chamber 211, the gas in the ventilation groove 3324 can enter the liquid storage chamber 211 through the liquid inlet hole 3323. When the user inhales, as the atomizing medium in the liquid storage chamber 211 is consumed, since the ventilation groove 3324 is connected to the liquid inlet hole 3323, the gas will enter the liquid storage chamber 211 through the ventilation groove 3324 and the liquid inlet hole 3323, so that the gas fills the space released by the consumption of the atomizing medium, ensures that the air pressure in the liquid storage chamber 211 is consistent with the external air pressure, and makes the liquid in the liquid storage chamber 211 smoothly flow to the atomizing core 320 through the liquid inlet hole 3323.

[0043] One end of the ventilation groove 3324 is connected to the liquid inlet hole 3323, and the other end of the ventilation groove 3324 extends in a curved and circuitous manner from the direction toward the mounting seat 410. The other end of the ventilation groove 3324 extends in a curved and circuitous manner from the air inlet hole 3322 toward the base assembly 400, so that the ventilation groove 3324 is curved. In view of the curved shape of the ventilation groove 3324, the ventilation groove 3324 has sufficient capacity to store the atomized medium from the liquid storage chamber 211, so as to prevent the atomized medium in the ventilation groove 3324 from overflowing from the ventilation groove 3324 to constitute leakage. At the same time, in the process of the gas entering the liquid storage chamber 211 from the ventilation groove 3324, the gas can carry the atomized medium in the ventilation groove 3324 back to the liquid storage chamber 211, thereby further preventing the atomized medium from leaking from the ventilation groove 3324.

[0044] In some embodiments, the ventilation groove 3324 includes a first ventilation segment 3324a and a second ventilation segment 3324b. The number of the first ventilation segment 3324a and the second ventilation segment 3324b can be multiple. The first ventilation segment 3324a extends along the circumference of the side tube 332, and multiple first ventilation segments 3324a are arranged at intervals along the axial direction of the side tube 332. The second ventilation segment 3324b is arc-shaped and connected to the end of the first ventilation segment 3324a, or the second ventilation segment 3324b is connected between two adjacent first ventilation segments 3324a, and one of the second ventilation segments 3324b is connected to the liquid inlet 3323.

[0045] The boss 340 is provided with a socket 341, and the conductive component 500 is disposed on the base component 400. The conductive component 500 can slide synchronously with the base component 400 relative to the atomizer component 300, and the conductive component 500 can be inserted into the socket 341. For example, the conductive component 500 may include a first electrode 510 and a second electrode 520, and the first electrode 510 and the second electrode 520 may both be columnar structures. There are two sockets 341, and the first electrode 510 can be inserted into one of the sockets 341, and the second electrode 520 can be inserted into the other socket 341.

[0046] Referring to FIGS. 2, 3, 4 and 6, the sealing member 230 is sleeved on the side tube 332. When in the initial position, the sealing member 230 blocks the liquid inlet hole 3323, so that the liquid inlet hole 3323 and the liquid storage chamber 211 are not connected to each other, that is, the atomized medium in the liquid storage chamber 211 cannot enter the liquid inlet hole 3323 and be absorbed by the atomizer core 320. After the side tube 332 slides a set distance relative to the sealing member 230 from the initial position, the sealing member 230 will completely open the liquid inlet hole 3323, so the sealing member 230 will no longer block the liquid inlet hole 3323, and the atomized medium in the liquid storage chamber 211 can enter the atomizer core 320 through the liquid inlet hole 3323. In the initial position, the seal 230 and the boss 340 are spaced apart. When the side tube 332 slides relative to the seal 230 until the liquid inlet hole 3323 is fully opened, the seal 230 can abut against the boss 340 to limit the sliding of the side tube 332 relative to the shell assembly 200.

[0047] A communication hole 3312 is provided on one side of the atomizer seat 310 facing the base assembly 400. For example, the communication hole 3312 can be provided on the bottom plate 331. The number of the communication holes 3312 can be two. An avoidance groove 3311 is also provided on the bottom plate 331. The air inlet 3322 and the avoidance groove 3311 are arranged at a distance along the axial direction of the atomizer seat 310. The avoidance groove 3311 is used to avoid the sliding of the base assembly 400 to prevent the bottom plate 331 from interfering with the sliding of the base assembly 400.

[0048] Referring to FIGS. 2, 3, 4 and 5, the atomizing core 320 includes a heating element 321 and a pin wire 322. The heating element 321 is disposed at the liquid inlet 3323. The heating element 321 can absorb the atomizing medium from the liquid inlet 3323. The pin wire 322 is disposed on the heating element 321. The pin wire 322 can be electrically connected to the conductive component 500, so that the battery 12 supplies power to the heating element 321 through the conductive component 500 and the pin core, so that the heating element 321 converts the electrical energy into heat, and then the atomizing medium is atomized under the action of the heat to form an aerosol. The pin wire 322 includes a first conductive wire and a second conductive wire. The first conductive wire is disposed in one of the connecting holes 3312 and is bent to extend to one of the plug holes 341. The second conductive wire is disposed in another connecting hole 3312 and is bent to extend to another plug hole 341. Of course, after the first conductive wire and the second conductive wire are installed, the two connecting holes 3312 can be blocked by a sealing plug or a sealant to prevent the gas from entering the atomization channel 3321 from the connecting hole 3312. The first conductive wire and the second conductive wire are clearance-matched with their respective corresponding plug holes 341. When the first electrode 510 is inserted into one of the plug holes 341, the first conductive wire is clamped between the first electrode 510 and the hole wall of one of the plug holes 341. When the second electrode 520 is inserted into the other plug hole 341, the second conductive wire is clamped between the second electrode 520 and the hole wall of the other plug hole 341, so that the electrical connection relationship between the conductive component 500 and the heating element 321 can be achieved.

[0049] When the aerosol atomization device is not in use, the base assembly 400 and the conductive assembly 500 are in the initial position, that is, in the first position. At this time, the first electrode 510 and the second electrode 520 are spaced apart from the plug hole 341 and are located outside the plug hole 341, so the conductive assembly 500 cannot contact the pin line 322, that is, the battery 12 cannot power the atomizer core 320 through the conductive assembly 500. When the base assembly 400 slides from the first position to the second position relative to the housing assembly 200, the first electrode 510 and the second electrode 520 will be inserted into the plug hole 341, so that the conductive assembly 500 contacts the pin line 322, that is, the battery 12 can power the atomizer core 320 through the conductive assembly 500.

[0050] Referring to FIGS. 2, 3, 4 and 5, in some embodiments, the base assembly 400 includes a mounting seat 410, and the mounting seat 410 is slidably connected to the liquid storage shell 210. The mounting seat 410 may include a base portion 413, a surrounding wall portion 414, a guide portion 412 and a limiting portion 415. The surrounding wall portion 414 is connected around the periphery of the base portion 413, and the base portion 413, the surrounding wall portion 414 and the housing assembly 200 are enclosed to form an accommodating chamber 411. The atomizer seat 310 is partially accommodated in the accommodating chamber 411, for example, the bottom plate 331 and the boss 340 of the atomizer seat 310 can be accommodated in the accommodating chamber 411. The guide portion 412 may be in the shape of a strip, and the guide portion 412 is protrudingly arranged on the outer surface of the surrounding wall portion 414. The guide portion 412 is slidably matched with the guide groove 212 on the liquid storage shell 210, so that the sliding accuracy of the mounting seat 410 and the entire base assembly 400 relative to the liquid storage shell 210 can be improved. Of course, the guide groove 212 can be arranged on the surrounding wall portion 414, and the guide portion 412 can also be arranged on the liquid storage shell 210. The limiting portion 415 may be roughly columnar, and the limiting portion 415 is also protrudingly arranged on the outer surface of the surrounding wall portion 414. The limiting portion 415 can cooperate with the first limiting hole 213 and the second limiting hole 214 on the liquid storage shell 210, so as to limit the sliding of the base assembly 400 relative to the housing assembly 200.

[0051] For example, when the mounting seat 410 and the base assembly 400 are located at the first position relative to the housing assembly 200, the limiting portion 415 cooperates with the first limiting hole 213. When the mounting seat 410 applies a thrust, the limiting portion 415 will withdraw from the first limiting hole 213, so that the mounting seat 410 and the base assembly 400 slide from the first position to the third position relative to the housing assembly 200. When the mounting seat 410 and the base assembly 400 are located at the third position, the limiting portion 415 cooperates with the second limiting hole 214. Therefore, by respectively cooperating with the limiting portion 415 with the first limiting hole 213 and the second limiting hole 214, the base can be limited in the first position and the third position relative to the housing assembly 200.

[0052] Referring to FIGS. 2, 3, 4 and 5, in some embodiments, the base assembly 400 may further include a mounting post 420, which is located in the accommodating cavity 411 and protrudes from the base portion 413, and the first electrode 510 and the second electrode 520 may protrude from the mounting post 420. When the mounting seat 410 and the base assembly 400 are located in the second position, the first electrode 510 and the second electrode 520 are inserted into the insertion hole 341, and the atomizer seat 310 may abut against the mounting post 420, thereby limiting the sliding of the base assembly 400 relative to the housing assembly 200, and ensuring that the base assembly 400 stays in the second position. The base assembly 400 may also include a guide column 460, which is protruding from the base portion 413. The guide column 460 can extend into the guide hole 232 of the seal 230. The guide column 460 and the guide hole 232 are slidably matched. Of course, the guide column 460 can seal the guide hole 232 to prevent the atomized medium in the liquid storage chamber 211 from entering the accommodating chamber 411 through the guide hole 232.

[0053] The accommodating chamber 411 and the ventilation groove 3324 are interconnected, so that the gas can enter the liquid storage chamber 211 through the accommodating chamber 411, the ventilation groove 3324 and the liquid inlet hole 3323. The annular gap 233 between the seal 230 and the atomizing assembly 300 is interconnected with the ventilation groove 3324 and the accommodating chamber 411. When the base assembly 400 is located at the third position relative to the shell assembly 200, the gas can enter the liquid storage chamber 211 through the accommodating chamber 411, the annular gap 233, the ventilation groove 3324 and the liquid inlet hole 3323. The annular gap 233 can provide a good avoidance space, on the one hand, to ensure that the accommodating chamber 411 is effectively connected to the ventilation groove 3324 through the annular gap 233, and on the other hand, it can also reasonably increase the amount of gas entering the ventilation groove 3324 from the accommodating chamber 411 per unit time, ensuring that the released space in the liquid storage chamber 211 is replenished by gas in time to increase the speed of supplying the atomized medium to the liquid inlet hole 3323. On the other hand, the contact area between the seal 230 and the side tube 332 can be reasonably reduced, thereby reasonably reducing the friction resistance between the seal 230 and the side tube 332.

[0054] Referring to FIGS. 2, 3, 4 and 5, in some embodiments, the base assembly 400 may further include an air guide column 440, which is connected to the base portion 413. The air guide column 440 includes a first air guide segment 441 and a second air guide segment 442. The first air guide segment 441 and the second air guide segment 442 may be coaxially arranged. The first air guide segment 441 is arranged on the base portion 413 and is located in the accommodating cavity 411. The second air guide segment 442 is arranged on a side of the base portion 413 away from the first air guide segment 441. A avoidance groove 3311 is arranged at a position of the bottom plate 331 corresponding to the air guide column 440, and the avoidance groove 3311 is used to accommodate the first air guide segment 441. The first air guide section 441 and the second air guide section 442 are both provided with an air inlet channel 443, which connects the receiving chamber 111 and the receiving chamber 411, and the external gas can enter the atomization channel 3321 through the receiving chamber 111, the air inlet channel 443, the receiving chamber 411 and the air inlet hole 3322 in sequence. By setting the avoidance groove 3311, when the base assembly 400 slides relative to the shell assembly 200, the avoidance groove 3311 provides an avoidance space for the movement of the air guide column 440, avoiding the interference between the bottom plate 331 and the air guide column 440, and also avoiding the bottom plate 331 from closing the air outlet of the air inlet channel 443, ensuring that the gas in the air inlet channel 443 passes through the avoidance groove 3311 and the receiving chamber 411 to enter the air inlet hole 3322. A through groove 444 is formed on the outer peripheral surface of the second air guide section 442, and the through groove 444 connects the receiving chamber 111 and the air inlet passage 443. The gas in the receiving chamber 111 can enter the air inlet passage 443 through the through groove 444. By providing the through groove 444, when the second air guide section 442 abuts against the battery 12, the battery 12 can abut against the end of the second air guide section 442. In view of the existence of the through groove 444, the gas in the receiving chamber 111 can smoothly pass through the through groove 444 and enter the air inlet passage 443, effectively avoiding the situation that the end of the air inlet passage 443 is blocked by the battery 12 and the gas in the receiving chamber 111 cannot enter the air inlet passage 443.

[0055] Referring to FIG. 5 and FIG. 7 , in some embodiments, the projection of the air inlet 3322 on the plane where the air outlet of the air inlet channel 443 is located is misaligned with the position of the air outlet of the air inlet channel 443, that is, the projection of the air outlet maintains a certain distance from the air outlet. In layman's terms, the air inlet 3322 is not located directly above the air guide column 440 and the air outlet. Therefore, in the case of leakage of the atomized medium from the air inlet 3322, the atomized medium leaking from the air inlet 3322 will not be able to drip into the air inlet channel 443 of the air guide column 440, thereby preventing the atomized medium from leaking into the receiving chamber 111 through the air inlet channel 443, preventing the atomized medium from leaking from the air inlet channel 443 to the outside of the entire aerosol device, and further preventing the atomized medium entering the receiving chamber 111 from the air inlet channel 443 from corroding the battery 12, thereby improving the reliability of the operation of the aerosol device. In fact, the atomized medium dripping from the air inlet 3322 can enter the accommodating chamber 411 , so the accommodating chamber 411 can store the atomized medium leaking from the air inlet 3322 , thereby preventing the atomized medium from entering the accommodating chamber 111 from the air inlet channel 443 .

[0056] Referring to FIG. 5 and FIG. 7 , in some embodiments, the position of the air outlet of the air inlet channel 443 is higher than the bottom wall of the mounting seat 410, and the position of the air inlet hole 3322 from the bottom wall of the mounting seat 410 is higher than the position of the air outlet of the air inlet channel 443 from the bottom wall of the mounting seat 410. In layman's terms, the air outlet of the air inlet channel 443 is higher than the bottom wall of the mounting seat 410, and the air inlet hole 3322 is higher than the air outlet of the air inlet channel 443. Since the air outlet of the air inlet channel 443 is higher than the bottom wall of the mounting seat 410, a certain amount of atomized medium can be stored in the accommodating chamber 411. When the liquid level formed by the atomized medium in the accommodating chamber 411 does not reach the air outlet of the air inlet channel 443, the atomized medium will not be able to enter the air inlet channel 443. Since the air inlet hole 3322 is higher than the air outlet of the air inlet channel 443, when there is too much atomized medium in the accommodating chamber 411 and the liquid level formed thereby reaches the air outlet, the atomized medium flows out from the air inlet channel 443, so as to prevent the liquid level formed by the gradually increasing atomized medium from reaching the air inlet hole 3322 and blocking the air inlet hole 3322, thereby improving the reliability of the aerosol generating device 20.

[0057] Referring to FIG. 5 and FIG. 7 , in some embodiments, the base assembly 400 may further include a liquid absorbing member 450, which may be a liquid absorbing cotton, etc. The liquid absorbing member 450 is disposed in the accommodating cavity 411 of the mounting seat 410 and is located below the air inlet 3322, and the height of the air guide column 440 is higher than the height of the liquid absorbing member 450. By providing the liquid absorbing member 450, the liquid absorbing member 450 can absorb the atomized medium in the accommodating cavity 411, thereby converting the atomized medium in the free state into the atomized medium in the bound state, and further preventing the atomized medium in the accommodating cavity 411 from entering the air inlet channel 443 and causing leakage. Since the liquid absorbing member 450 is disposed on the side of the atomizing seat 310 and is located above the liquid absorbing member 450, when the base assembly 400 moves to the third position relative to the housing assembly 200, the liquid absorbing member 450 will not pose a risk of blocking the air inlet 3322, thereby avoiding the aerosol generating device 20 from being unable to work properly due to the air inlet 3322 being blocked by the liquid absorbing member 450, thereby improving the reliability of the aerosol generating device 20. Since the height of the air guide column 440 is higher than the height of the liquid absorbing member 450, the height of the air outlet is higher than the liquid absorbing member 450, which is also conducive to preventing the atomized medium in the liquid absorbing member 450 from entering the air inlet channel 443 to cause leakage.

[0058] 2, 5 and 7, in some embodiments, the aerosol generating device 20 may further include a circuit board 610 and an airflow sensor 620, which are disposed on a side of the mounting base 410 away from the atomizing base 310. The conductive component 500 is electrically connected to the circuit board 610, the airflow sensor 620 is disposed on the circuit board 610, and the vent column 430 is provided with a sensing airway 431, which communicates the airflow sensor 620 and the accommodating chamber 411. When the user inhales at the end of the inhalation channel 2221, the external gas will enter the atomization channel 3321 from the receiving chamber 111, the air inlet channel 443, the containing chamber 411 and the air inlet hole 3322 in sequence. It can be understood that at the moment when the user inhales, there is a change in air pressure in the atomization channel 3321. The airflow sensor 620 can detect the change in air pressure in the atomization channel 3321 by sensing the airway 431 and the containing chamber 411, so that the airflow sensor 620 can feedback a working signal to the circuit board 610, so that the circuit board 610 controls the battery 12 to supply power to the atomization core 320 through the conductive component 500 to generate heat, so that the atomization medium on the atomization core 320 is atomized to form an aerosol discharged into the atomization channel 3321. The gas in the atomization channel 3321 will carry the aerosol and be discharged from the inhalation channel 2221, so that the user can inhale the aerosol from the end of the inhalation channel 2221.

[0059] The working principle of the aerosol generating device 20 is described below:

[0060] Referring to FIG. 2, FIG. 3 and FIG. 7, first, the aerosol generating device 20 is in an idle state before being used. At this time, the base assembly 400 is in the first position, the conductive assembly 500 is spaced apart from the plug hole 341, and the conductive assembly 500 is not inserted into the plug hole 341 and contacts the pin line 322 to form an electrical conduction relationship, so the battery 12 cannot supply power to the atomizing core 320 through the conductive assembly 500 and the pin line 322, that is, the aerosol generating device 20 is in a power-off state, even if the user inhales in the air inhalation channel 2221 due to the mist operation, the atomizing core 320 will not generate heat to atomize the atomizing medium, thereby avoiding the waste of atomizing medium and energy, and improving the reliability of the aerosol generating device 20. At the same time, in the first position, the sealing member 230 will block the liquid inlet hole 3323, and the atomizing medium in the liquid storage chamber 211 cannot enter the atomizing core 320 through the liquid inlet hole 3323, that is, the aerosol generating device 20 is in a liquid-off state. Therefore, there will be no leakage of the atomizing medium on the atomizing core 320, thereby preventing the entire aerosol generating device 20 from leaking the atomizing medium, further improving the reliability of the aerosol generating device 20. Therefore, the aerosol generating device 20 is in an idle state, the base assembly 400 is in the first position relative to the housing assembly 200, and the aerosol generating device 20 is in a power-off and liquid-off state at the same time.

[0061] Referring to FIG. 8 , when the aerosol generating device 20 needs to be used, the atomizer assembly 300 can be fixed relative to the shell assembly 200, that is, the atomizer assembly 300 and the shell assembly 200 are fixed, and a thrust is applied to the base assembly 400, so that the base assembly 400 moves from the first position to the second position relative to the fixed atomizer assembly 300 and the shell assembly 200. At this time, the conductive component 500 will be inserted into the plug hole 341, so that the conductive component 500 contacts the pin line 322 to form an electrical conduction relationship, so the battery 12 can supply power to the atomizer core 320 through the conductive component 500 and the pin line 322, that is, the aerosol generating device 20 is in a power-on state. However, in view of the fact that the atomizer assembly 300 is fixed relative to the shell assembly 200 during the movement of the base assembly 400 from the first position to the second position, the atomizer assembly 300 cannot slide relative to the shell assembly 200, so that the seal 230 still blocks the liquid inlet hole 3323, that is, the liquid in the liquid storage chamber 211 cannot enter the atomizer core 320 through the liquid inlet hole 3323, and the aerosol generating device 20 is still in the liquid-free state. Therefore, the base assembly 400 is in the second position relative to the shell assembly 200, and the aerosol generating device 20 is in the liquid-free state at the same time, but in the power-on state.

[0062] Referring to FIG9 , finally, the base assembly 400 is continuously applied with thrust, so that the base assembly 400 moves from the second position to the third position relative to the shell assembly 200. In the process of applying thrust to the base assembly 400, the limiting portion 415 on the mounting seat 410 will be disengaged from the first limiting hole 213. At this time, the base assembly 400 pushes the atomizer assembly 300 to move synchronously relative to the shell assembly 200. When the atomizer assembly 300 moves to the third position, the limiting portion 415 on the mounting seat 410 will be inserted into the second limiting hole 214, and the atomizer assembly 300 stops moving relative to the shell assembly 200. At this time, the sealing member 230 opens the liquid inlet hole 3323, so that the liquid storage chamber 211 and the liquid inlet hole 3323 are interconnected, so the atomizer medium in the liquid storage chamber 211 can enter the atomizer core 320 through the liquid inlet hole 3323, that is, the aerosol generating device 20 is in a liquid-passing state, and the solid arrow in FIG9 is the flow trajectory of the atomizer medium. Since the atomizer assembly 300 and the base assembly 400 both move synchronously relative to the housing assembly 200, the conductive assembly 500 is still in contact with the pin line 322, that is, the aerosol generating device 20 is still in a state where it can be powered. Therefore, the base assembly 400 is in the third position relative to the housing assembly 200, and the aerosol generating device 20 is in a liquid-passing state and a power-on state at the same time. At this time, the aerosol generating device 20 is completely ready, and the user can inhale at the end of the inhalation channel 2221. The dotted arrow in FIG9 is the flow trajectory of the gas.
