Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an aerosol generating device and an aerosol generating apparatus including the aerosol generating device. Background Technology

[0002] Aerosol generators atomize liquid atomizing media into aerosols that users can inhale, making them popular among users. However, in traditional aerosol generators, condensation or leakage of atomizing media can occur in the atomization channels of the atomizing base during use. This condensation or leakage is discharged through the air inlet on the atomizing base and collected by the base of the atomizer. When too much condensation or leakage accumulates, the air inlet can become clogged, affecting the reliability of the aerosol generator. Summary of the Invention

[0003] One technical problem addressed by this application is how to improve the reliability of aerosol generating devices.

[0006] An atomizing component is disposed in the liquid storage chamber. The atomizing component is used to heat the atomizing medium to atomize it into an aerosol. The atomizing component includes an atomizing seat, which is provided with an atomizing channel. An air inlet is also provided on the side of the atomizing seat, and the air inlet is connected to the atomizing channel.

[0010] The air outlet of the air intake channel is positioned higher than the bottom wall of the mounting base, and the distance between the air inlet and the bottom wall of the mounting base is higher than the distance between the air outlet of the air intake channel and the bottom wall of the mounting base; and / or the projection of the air inlet onto the plane where the air outlet of the air intake channel is located is offset from the position of the air outlet of the air intake channel.

The first air guide section is disposed on the mounting base and located within the receiving cavity. The second air guide section is disposed on the side of the mounting base opposite to the first air guide section. The base plate is provided with a clearance groove corresponding to the position of the air guide column. The clearance groove is used to accommodate the first air guide section. The air inlet and the clearance groove are spaced apart along the axial direction of the atomizing base.

[0014] In one embodiment, the aerosol generating device further includes a conductive component connected to the mounting base. The atomizing base further includes a body and a boss. The boss is disposed on the outer peripheral surface of the body and has a socket on the side of the boss facing the mounting base. The atomizing component further includes an atomizing core housed in the atomizing channel. The atomizing core includes lead wires that extend into the socket. The conductive component can mate with the socket and be electrically connected to the lead wires.

[0015] And / or, the aerosol generating device further includes an airflow sensor connected to the mounting base, and the base assembly further includes a ventilation column with a sensing air passage that connects the airflow sensor and the receiving cavity.

[0016] In one embodiment, the housing assembly further includes a liquid storage shell, a seal, and a nozzle rod. The liquid storage shell has a first end and a second end opposite to each other. The nozzle rod is disposed at the first end of the liquid storage shell. The nozzle rod is sealed to the atomizing seat. An air intake channel is formed inside the nozzle rod. The air intake channel communicates with the atomizing channel. The mounting seat is disposed at the second end of the liquid storage shell.

[0017] The sealing element is fitted between the liquid storage shell and the atomizing seat, and forms the liquid storage cavity and the receiving cavity on opposite sides of the liquid storage shell, respectively. The atomizing seat extends through the sealing element from the first end of the liquid storage shell to the second end of the liquid storage shell. A part of the atomizing seat is located in the liquid storage cavity and another part is located in the receiving cavity.

[0018] In one embodiment, the mounting base is movable relative to the liquid storage shell and can drive the atomizing seat to move relative to the sealing element, and a first position and a third position are defined along the movement trajectory of the mounting base;

[0019] The atomizing seat has a liquid inlet hole that connects to the atomizing channel. When the mounting seat is in the first position, the sealing element closes the liquid inlet hole to block the connection between the liquid storage chamber and the atomizing channel. When the mounting seat is in the third position, the liquid inlet hole is connected to the liquid storage chamber to allow the liquid storage chamber to connect with the atomizing channel.

[0020] In one embodiment, an air exchange groove is also provided on the outer periphery of the atomizing seat. One end of the air exchange groove is connected to the liquid inlet hole, and the other end of the air exchange groove extends in a curved and meandering manner from the liquid inlet hole toward the mounting seat.

The aerosol generating apparatus and the battery are installed inside the housing, and the aerosol generating apparatus is electrically connected to the battery.

[0028] One technical advantage of one embodiment of this application is that, since the air inlet is located on the side of the atomizing seat, the liquid surface formed by the condensed substance or atomizing medium in the accommodating cavity cannot reach the air inlet, thus avoiding the risk of the air inlet being blocked and improving the reliability of the aerosol generating device.

Detailed Implementation

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] See Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this application provides an aerosol generating device 30, including an aerosol generating unit 20 and a main unit 10. The aerosol generating unit 20 and the main unit 10 can be detachably connected, or they can be non-detachably connected. The main unit 10 includes a battery 12 and a housing 11. The battery 12 is located inside the housing 11. The aerosol generating unit 20 can be inserted into the housing 11, allowing it to slide relative to the housing 11. The housing 11 has a receiving cavity 111, in which the battery 12 is housed. The side of the receiving cavity 111 away from the aerosol generating unit 20 can communicate with the outside. The aerosol generating unit 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. The conductive assembly is electrically connected to the battery 12.

[0046] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the housing assembly 200 includes a liquid storage shell 210, a nozzle rod 220, and a seal 230. A liquid storage chamber 211 is provided within the housing assembly 200 to contain the liquid atomizing medium. The liquid storage shell 210, nozzle rod 220, seal 230, and atomizing assembly 300 can collectively form the liquid storage chamber 211. The nozzle rod 220 can be integrally formed with the liquid storage shell 210. The liquid storage shell 210 has a first end and a second end. The nozzle rod 220 is located within the liquid storage shell 210 and connected to the first end of the liquid storage shell 210. The nozzle rod 220 extends a certain length towards the second end. An air intake channel 2221 is provided within the nozzle rod 220. The end of the air intake channel 2221 near the first end of the liquid storage shell 210 is connected to the outside, allowing the user to draw aerosol from the end of the air intake channel 2221.

[0047] See Figure 1 , Figure 2 and Figure 3The liquid storage shell 210 may have 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. Both the first limiting hole 213 and the second limiting hole 214 are 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. A guide groove 212 may also be recessed on the inner wall surface of the liquid storage shell 210, which slides with the base assembly 400, thereby improving the sliding accuracy of the base assembly 400 relative to the liquid storage shell 210.

[0048] See Figure 1 , Figure 2 and Figure 3 The sealing element 230 can be made of a flexible material, such as silicone. It can be fixedly installed within the liquid storage shell 210, allowing synchronous movement between the two. This provides a good seal for the liquid storage cavity 211. The sealing element 230 is fitted onto the atomizing assembly 300 and can slide relative to it. The shell assembly 200 may also include a reinforcing element 240, which can be made of stainless steel, giving it a stiffness greater than that of the sealing element 230. The reinforcing element 240 is generally annular and embedded within the sealing element 230. By including the reinforcing element 240, the stiffness and strength of the sealing element 230 can be reasonably improved, preventing significant deformation during sliding relative to the atomizing assembly 300 and thus enhancing its sealing performance over the liquid storage cavity 211. A guide hole 232 may be provided in the seal 230, and the guide hole 232 slides with the base assembly 400.

[0049] See Figure 2 , Figure 3 and Figure 7 The sealing element 230 has a guide surface 231 on the side facing the liquid storage chamber 211. The guide surface 231 is inclined, so that the guide surface 231 is set at an angle relative to the axial direction of the liquid storage shell 210. The guide surface 231 is inclined from the side away from the component towards the side closer to the atomizing component 300. By setting the guide surface 231, the atomizing medium in the liquid storage chamber 211 can be well guided, so that the atomizing medium can smoothly enter the atomizing component 300. The end of the sealing element 230 away from the liquid storage chamber 211 is spaced apart from the atomizing component 300, so that an annular gap 233 is formed between the sealing element 230 and the atomizing component 300.

[0050] See Figure 2 , Figure 3, Figure 4 and Figure 6 In some embodiments, the atomizing assembly 300 includes an atomizing base 310 and an atomizing core 320. The atomizing base 310 includes a body portion 330 and a boss 340, with the boss 340 protruding from the side of the body portion 330. The body portion 330 may include a base plate 331 and a side cylinder 332, with the side cylinder 332 surrounding the edge of the base plate 331. The boss 340 may protrude radially from the side cylinder 332, forming an atomizing channel 3321. The atomizing core 320 is located within the atomizing channel 3321. The side cylinder 332 has a liquid inlet 3323 and an air inlet 3322, which are spaced a certain distance apart along the axial direction of the side cylinder 332. The liquid inlet 3323 may connect the atomizing 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 the end of the liquid inlet hole 3323 that connects 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 come into contact with the atomizing core 320 and penetrate into the atomizing core 320. The atomizing core 320 can generate heat, thereby causing the atomizing medium that has penetrated into the atomizing core 320 to absorb heat and atomize to form an aerosol. The mouthpiece rod 220 can be inserted into the atomizing channel 3321, and the mouthpiece rod 220 is sealed to the atomizing seat 310. Therefore, the mouthpiece rod 220 can provide a good seal for the atomizing channel 3321, and the mouthpiece rod 220 can slide relative to the atomizing seat 310 within the atomizing channel 3321. The suction channel 2221 of the nozzle rod 220 is connected to the atomization channel 3321. When the user inhales at the end of the suction channel 2221, the aerosol in the atomization channel 3321 can enter the suction channel 2221 and be absorbed by the user. The air inlet 3322 is provided on the side tube 332, so the air inlet 3322 is located on the side of the atomizing base 310. The air inlet 3322 can maintain a certain distance from the base plate 331 along the axial direction of the side tube 332. When the user inhales, the gas can enter the atomization channel 3321 through the air inlet 3322 to carry the aerosol into the suction channel 2221.

[0051] See Figure 2 , Figure 3 , Figure 4 and Figure 6The side cylinder 332 is also provided with a ventilation groove 3324, which can be connected to the liquid inlet 3323. When the liquid inlet 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 3323. When the user draws in the liquid, as the atomizing medium in the liquid storage chamber 211 is consumed, since the ventilation groove 3324 is connected to the liquid inlet 3323, the gas will enter the liquid storage chamber 211 through the ventilation groove 3324 and the liquid inlet 3323. This allows the gas to fill the space released by the consumption of the atomizing medium, ensuring that the air pressure in the liquid storage chamber 211 is consistent with the external air pressure, so that the liquid in the liquid storage chamber 211 can flow smoothly to the atomizing core 320 through the liquid inlet 3323.

[0052] One end of the ventilation groove 3324 is connected to the liquid inlet 3323, and the other end of the ventilation groove 3324 extends in a curved and tortuous manner from the air inlet 3322 toward the base assembly 400, making the ventilation groove 3324 curved. Because the ventilation groove 3324 is curved, it has sufficient capacity to store the atomized medium from the liquid storage chamber 211, preventing the atomized medium from overflowing from the ventilation groove 3324 and causing leakage. Simultaneously, during the process of gas entering the liquid storage chamber 211 from the ventilation groove 3324, the gas can carry the atomized medium from the ventilation groove 3324 back to the liquid storage chamber 211, thereby further preventing leakage of the atomized medium from the ventilation groove 3324.

[0053] In some embodiments, the ventilation groove 3324 includes a first ventilation section 3324a and a second ventilation section 3324b. There can be multiple first ventilation sections 3324a and second ventilation sections 3324b. The first ventilation section 3324a extends circumferentially along the side cylinder 332, and multiple first ventilation sections 3324a are spaced apart axially along the side cylinder 332. The second ventilation section 3324b is arc-shaped and connected to the end of the first ventilation section 3324a, or the second ventilation section 3324b is connected between two adjacent first ventilation sections 3324a, and one of the second ventilation sections 3324b communicates with the liquid inlet 3323.

[0054] The boss 340 has a socket 341. A conductive component 500 is mounted on the base assembly 400. The conductive component 500 can slide synchronously with the base assembly 400 relative to the atomizing assembly 300, and can be inserted into the socket 341. For example, the conductive component 500 may include a first electrode 510 and a second electrode 520, both of which can be columnar structures. There are two sockets 341; the first electrode 510 can be inserted into one socket 341, and the second electrode 520 can be inserted into the other socket 341.

[0055] See Figure 2 , Figure 3 , Figure 4 and Figure 6 The sealing element 230 is sleeved on the side cylinder 332. In the initial position, the sealing element 230 blocks the liquid inlet hole 3323, making the liquid inlet hole 3323 and the liquid storage chamber 211 disconnected. That is, the atomizing medium in the liquid storage chamber 211 cannot enter the liquid inlet hole 3323 and be absorbed by the atomizing core 320. After the side cylinder 332 slides a set distance relative to the sealing element 230 from the initial position, the sealing element 230 will completely open the liquid inlet hole 3323. Therefore, the sealing element 230 will no longer block the liquid inlet hole 3323, and the atomizing medium in the liquid storage chamber 211 can enter the atomizing 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 cylinder 332 slides relative to the seal 230 until the liquid inlet 3323 is fully open, the seal 230 can abut against the boss 340, thereby limiting the sliding of the side cylinder 332 relative to the housing assembly 200.

[0056] The atomizing base 310 has a connecting hole 3312 on the side facing the base assembly 400. For example, the connecting hole 3312 can be set on the base plate 331, and there can be two connecting holes 3312. The base plate 331 also has a relief groove 3311. The air inlet 3322 and the relief groove 3311 are spaced apart along the axial direction of the atomizing base 310. The relief groove 3311 is used to avoid the sliding of the base assembly 400 and prevent the base plate 331 from interfering with the sliding of the base assembly 400.

[0057] See Figure 2 , Figure 3 , Figure 4 and Figure 5The atomizing core 320 includes a heating element 321 and a lead wire 322. The heating element 321 is disposed at the liquid inlet 3323 and can absorb the atomizing medium from the liquid inlet 3323. The lead wire 322 is disposed on the heating element 321 and 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 lead wire, thereby allowing the heating element 321 to convert electrical energy into heat, which in turn causes the atomizing medium to atomize and form an aerosol under the action of heat. The lead wire 322 includes a first conductive wire and a second conductive wire. The first conductive wire passes through one of the connecting holes 3312 and bends to extend into one of the sockets 341, and the second conductive wire passes through another connecting hole 3312 and bends to extend into another socket 341. Of course, after the first and second conductive wires are installed, the two connecting holes 3312 can be sealed with sealing plugs or sealant to prevent gas from entering the atomizing channel 3321 through the connecting holes 3312. The first and second conductive wires are clearance-fitted with their respective sockets 341. When the first electrode 510 is inserted into one of the sockets 341, the first conductive wire is sandwiched between the first electrode 510 and the wall of one of the sockets 341. When the second electrode 520 is inserted into the other socket 341, the second conductive wire is sandwiched between the second electrode 520 and the wall of the other socket 341. In this way, the electrical connection between the conductive component 500 and the heating element 321 can be achieved.

[0058] When the aerosol atomizing device is not in use, the base assembly 400 and the conductive assembly 500 are in their initial positions, i.e., the first position. At this time, the first electrode 510 and the second electrode 520 are spaced apart from the socket 341 and located outside the socket 341. Therefore, the conductive assembly 500 cannot contact the lead wire 322, meaning the battery 12 cannot supply power to the atomizing core 320 through the conductive assembly 500. When the base assembly 400 slides relative to the housing assembly 200 from the first position to the second position, the first electrode 510 and the second electrode 520 will be inserted into the socket 341, thereby allowing the conductive assembly 500 to contact the lead wire 322. In other words, the battery 12 can supply power to the atomizing core 320 through the conductive assembly 500.

[0059] See Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, the base assembly 400 includes a mounting base 410, which is slidably connected to the liquid reservoir 210. The mounting base 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 surrounds the periphery of the base portion 413, and the base portion 413, the surrounding wall portion 414, and the housing assembly 200 enclose a receiving cavity 411. The atomizing seat 310 is partially received in the receiving cavity 411; for example, the base plate 331 and the boss 340 of the atomizing seat 310 may be received in the receiving cavity 411. The guide portion 412 can be strip-shaped and protrudes from the outer surface of the enclosure portion 414. The guide portion 412 slides in conjunction with the guide groove 212 on the liquid storage shell 210, thereby improving the sliding accuracy of the mounting base 410 and the entire base assembly 400 relative to the liquid storage shell 210. Of course, the guide groove 212 can be provided on the enclosure portion 414, and the guide portion 412 can also be provided on the liquid storage shell 210. The limiting portion 415 can be approximately columnar and also protrudes from the outer surface of the enclosure 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, thereby limiting the sliding of the base assembly 400 relative to the shell assembly 200.

[0060] For example, when the mounting base 410 and the base assembly 400 are in the first position relative to the housing assembly 200, the limiting part 415 engages with the first limiting hole 213. When the mounting base 410 applies a pushing force, the limiting part 415 will disengage from the first limiting hole 213, thereby allowing the mounting base 410 and the base assembly 400 to slide relative to the housing assembly 200 from the first position to the third position. When the mounting base 410 and the base assembly 400 are in the third position, the limiting part 415 engages with the second limiting hole 214. Therefore, by engaging the limiting part 415 with the first limiting hole 213 and the second limiting hole 214 respectively, the base can be limited relative to the housing assembly 200 in the first and third positions.

[0061] See Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, the base assembly 400 may further include a mounting post 420, which is located within the receiving cavity 411 and protrudes from the base portion 413. The first electrode 510 and the second electrode 520 may protrude from the mounting post 420. When the mounting base 410 and the base assembly 400 are in the second position, the first electrode 510 and the second electrode 520 are inserted into the insertion hole 341, and the atomizing seat 310 can 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 remains in the second position. The base assembly 400 may also include a guide post 460, which protrudes from the base portion 413 and can extend into the guide hole 232 of the seal 230. The guide post 460 slides in the guide hole 232. Of course, the guide post 460 can seal the guide hole 232 to prevent the atomizing medium in the liquid storage chamber 211 from entering the receiving chamber 411 through the guide hole 232.

[0062] The receiving cavity 411 and the ventilation groove 3324 are interconnected, allowing gas to enter the storage cavity 211 through the receiving cavity 411, the ventilation groove 3324, and the liquid inlet 3323. The annular gap 233 between the sealing element 230 and the atomizing assembly 300 is interconnected with the ventilation groove 3324 and the receiving cavity 411. When the base assembly 400 is in the third position relative to the housing assembly 200, gas can enter the storage cavity 211 through the receiving cavity 411, the annular gap 233, the ventilation groove 3324, and the liquid inlet 3323. This annular gap 233 provides good clearance space, ensuring that the receiving cavity 411 is effectively connected to the ventilation groove 3324 through the annular gap 233, and also reasonably increasing the amount of gas entering the ventilation groove 3324 from the receiving cavity 411 per unit time, ensuring that the release space in the storage cavity 211 is replenished by gas in a timely manner to increase the speed of supplying the atomizing medium to the liquid inlet 3323. On the other hand, it can reasonably reduce the contact area between the seal 230 and the side cylinder 332, thereby reasonably reducing the frictional resistance between the seal 230 and the side cylinder 332.

[0063] See Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, the base assembly 400 may further include an air guide column 440 connected to the base portion 413. The air guide column 440 includes a first air guide section 441 and a second air guide section 442, which may be coaxially arranged. The first air guide section 441 is disposed in the base portion 413 and located within the receiving cavity 411, while the second air guide section 442 is disposed on the side of the base portion 413 opposite to the first air guide section 441. The base plate 331 is provided with a clearance groove 3311 corresponding to the position of the air guide column 440, which is used to accommodate the first air guide section 441. Both the first air guide section 441 and the second air guide section 442 are provided with air intake channels 443. The air intake channels 443 connect the receiving cavity 111 and the receiving cavity 411. External gas can enter the atomizing channel 3321 in sequence through the receiving cavity 111, the air intake channel 443, the receiving cavity 411, and the air inlet 3322. By setting the clearance groove 3311, during the sliding process of the base assembly 400 relative to the housing assembly 200, the clearance groove 3311 provides clearance space for the movement of the air guide column 440, avoiding interference between the base plate 331 and the air guide column 440, and also avoiding the base plate 331 from sealing the air outlet of the air intake channel 443, ensuring that the gas in the air intake channel 443 passes through the clearance groove 3311 and the receiving cavity 411 to enter the air inlet 3322. A through groove 444 is recessed on the outer peripheral surface of the second air guide section 442. The through groove 444 connects the receiving cavity 111 and the air intake channel 443. Gas in the receiving cavity 111 can enter the air intake channel 443 through the through groove 444. By providing the through groove 444, when the second air guide section 442 is in contact with the battery 12, the battery 12 can contact the end of the second air guide section 442. Due to the presence of the through groove 444, gas in the receiving cavity 111 can smoothly enter the air intake channel 443 through the through groove 444, effectively preventing gas in the receiving cavity 111 from being unable to enter the air intake channel 443 due to the end of the air intake channel 443 being blocked by the battery 12.

[0064] See Figure 5 and Figure 7In some embodiments, the projection of the air inlet 3322 onto the plane of the air outlet of the air intake channel 443 is offset from the position of the air outlet of the air intake channel 443. That is, the projection of the air outlet is at a certain distance from the air outlet. In simple terms, the air inlet 3322 is not located directly above the air guide column 440 and the air outlet. Therefore, in the event of leakage of the atomizing medium from the air inlet 3322, the atomizing medium leaking from the air inlet 3322 will not drip into the air intake channel 443 of the air guide column 440, thus preventing the atomizing medium from leaking into the receiving cavity 111 through the air intake channel 443. This prevents the atomizing medium from leaking from the air intake channel 443 outside the entire aerosol device, thereby preventing the atomizing medium entering the receiving cavity 111 from the air intake channel 443 from corroding the battery 12, thereby improving the reliability of the aerosol device. In fact, the atomized medium dripping from the air inlet 3322 can enter the receiving cavity 411. Therefore, the receiving cavity 411 can store the atomized medium leaking from the air inlet 3322, preventing the atomized medium from entering the receiving cavity 111 from the air intake channel 443.

[0065] See Figure 5 and Figure 7 In some embodiments, the outlet of the air intake channel 443 is positioned higher than the bottom wall of the mounting base 410, and the distance between the air inlet 3322 and the bottom wall of the mounting base 410 is higher than the distance between the outlet of the air intake channel 443 and the bottom wall of the mounting base 410. In simpler terms, the outlet of the air intake channel 443 is higher than the bottom wall of the mounting base 410, and the air inlet 3322 is higher than the outlet of the air intake channel 443. Since the outlet of the air intake channel 443 is higher than the bottom wall of the mounting base 410, a certain amount of atomizing medium can be stored in the receiving cavity 411. When the liquid level formed by the atomizing medium in the receiving cavity 411 does not reach the outlet of the air intake channel 443, the atomizing medium will not be able to enter the air intake channel 443. Since the air inlet 3322 is higher than the air outlet of the air inlet channel 443, when there is too much atomizing medium in the receiving cavity 411 and the liquid surface formed by it reaches the air outlet, the atomizing medium flows out from the air inlet channel 443, thus preventing the liquid surface formed by the gradually increasing atomizing medium from reaching the air inlet 3322 and blocking it, thereby improving the reliability of the aerosol generating device 20.

[0066] See Figure 5 and Figure 7In some embodiments, the base assembly 400 may further include a liquid-absorbing element 450, which may be a liquid-absorbing cotton or the like. The liquid-absorbing element 450 is disposed within the receiving cavity 411 of the mounting base 410 and located below the air inlet 3322, and the height of the air guide column 440 is higher than the height of the liquid-absorbing element 450. By providing the liquid-absorbing element 450, it can adsorb the atomized medium in the receiving cavity 411, thereby converting the free atomized medium into a bound atomized medium, further preventing the atomized medium in the receiving cavity 411 from entering the air inlet channel 443 and causing leakage. Since the liquid suction element 450 is located on the side of the atomizing base 310 and above it, when the base assembly 400 moves to the third position relative to the housing assembly 200, the liquid suction element 450 will not pose a risk of blocking the air inlet 3322. This avoids the aerosol generating device 20 from malfunctioning due to the air inlet 3322 being blocked by the liquid suction element 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 suction element 450, the height of the air outlet is also higher than that of the liquid suction element 450, which also helps prevent the atomizing medium in the liquid suction element 450 from entering the air inlet channel 443 and causing leakage.

[0067] See Figure 2 , Figure 5 and Figure 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 the side of the mounting base 410 opposite to 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 ventilation column 430 has a sensing air passage 431 that connects the airflow sensor 620 and the receiving cavity 411. The user inhales from the end of the inhalation channel 2221. External gas enters the atomization channel 3321 sequentially from the receiving cavity 111, the air inlet channel 443, the receiving cavity 411, and the air inlet 3322. It is understood that at the moment of inhalation, there is a pressure change in the atomization channel 3321. The airflow sensor 620 can detect this pressure change by sensing the air passage 431 and the receiving cavity 411. This causes the airflow sensor 620 to send a signal to the circuit board 610 indicating that it is ready to operate. The circuit board 610 then controls the battery 12 to supply power to the atomizing core 320 through the conductive component 500 to generate heat. This heat causes the atomizing medium on the atomizing core 320 to atomize, forming an aerosol that is discharged into the atomization channel 3321. The gas in the atomization channel 3321 carries the aerosol and is discharged from the inhalation channel 2221, allowing the user to inhale the aerosol from the end of the inhalation channel 2221.

[0068] The working principle of the aerosol generating device 20 is described below:

[0069] See Figure 2 , Figure 3 and Figure 7 First, the aerosol generating device 20 is in an idle state before use. At this time, the base assembly 400 is in the first position, and the conductive component 500 is spaced apart from the socket 341. The conductive component 500 is not inserted into the socket 341 but is in contact with the pin wire 322 to form an electrical connection. Therefore, the battery 12 cannot supply power to the atomizing core 320 through the conductive component 500 and the pin wire 322. That is, the aerosol generating device 20 is in a power-off state. Even if the user draws air through the inhalation channel 2221 due to misting operation, the atomizing core 320 will not be able to 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 component 230 will block the liquid inlet 3323, and the atomizing medium in the liquid storage chamber 211 cannot enter the atomizing core 320 through the liquid inlet 3323. That is, the aerosol generating device 20 is in a liquid-off state. Therefore, there will be no leakage of atomizing medium on the atomizing core 320, thereby avoiding leakage of atomizing medium in the entire aerosol generating device 20 and further improving the reliability of the aerosol generating device 20. Thus, the aerosol generating device 20 is in an idle state, with the base assembly 400 in the first position relative to the housing assembly 200, and the aerosol generating device 20 is simultaneously in a power-off and liquid-off state.

[0070] See Figure 8 Then, when the aerosol generating device 20 is needed, the atomizing component 300 can be fixed relative to the housing component 200, that is, the atomizing component 300 and the housing component 200 are fixed. A pushing force is applied to the base component 400, so that the base component 400 moves from the first position to the second position relative to the fixed atomizing component 300 and the housing component 200. At this time, the conductive component 500 will be inserted into the socket 341, so that the conductive component 500 contacts the lead wire 322 to form an electrical conduction relationship. Therefore, the battery 12 can supply power to the atomizing core 320 through the conductive component 500 and the lead wire 322, that is, the aerosol generating device 20 is in a power-on state. However, since the atomizing component 300 is fixed relative to the housing component 200 during the movement of the base assembly 400 from the first position to the second position, the atomizing component 300 cannot slide relative to the housing component 200. This means the seal 230 still blocks the liquid inlet 3323, preventing liquid in the storage chamber 211 from entering the atomizing core 320 through the liquid inlet 3323. Therefore, the aerosol generating device 20 remains in a liquid-off state. Thus, while the base assembly 400 is in the second position relative to the housing component 200, the aerosol generating device 20 is simultaneously in a liquid-off state, but is still energized.

[0071] See Figure 9Finally, a pushing force is applied to the base assembly 400, causing it to move relative to the housing assembly 200 from the second position to the third position. During this pushing process, the limiting part 415 on the mounting base 410 disengages from the first limiting hole 213. At this time, the base assembly 400 pushes the atomizing assembly 300 to move synchronously relative to the housing assembly 200. When the atomizing assembly 300 reaches the third position, the limiting part 415 on the mounting base 410 inserts into the second limiting hole 214, and the atomizing assembly 300 stops moving relative to the housing assembly 200. At this time, the seal 230 opens the liquid inlet 3323, allowing the liquid storage chamber 211 to communicate with the liquid inlet 3323. Therefore, the atomizing medium in the liquid storage chamber 211 can enter the atomizing core 320 through the liquid inlet 3323, meaning the aerosol generating device 20 is in a liquid-flow state. Figure 9 The solid arrow in the middle represents the flow trajectory of the atomizing medium. Since the atomizing component 300 and the base component 400 move synchronously relative to the housing component 200, the conductive component 500 remains in contact with the pin line 322, meaning the aerosol generating device 20 remains energized. Therefore, the base component 400 is in the third position relative to the housing component 200, and the aerosol generating device 20 is simultaneously in a liquid-flowing and energized state. At this time, the aerosol generating device 20 is fully ready, and the user can inhale from the end of the suction channel 2221. Figure 9 The dashed arrow in the middle represents the gas flow trajectory.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
