[0069] See also Figure 2 and Figure 3Specifically, the liquid storage component 100 includes a first shell 1, a base 2 and a first sealing member 3. The first shell 1 has an air outlet pipe 11 inside. The base 2 is at least partially disposed in the first shell 1 and cooperates with the first shell 1 to form a liquid storage chamber 12, and the liquid storage chamber 12 is used to store the aerosol generating matrix. In the present embodiment, the base 2 is completely disposed in the first shell 1. The base 2 has an air outlet hole 21 and a lower liquid hole 22. The air outlet pipe 11 is connected to the air outlet hole 21. The first sealing member 3 is disposed in the first shell 1 and is located between the base 2 and the first shell 1. One end of the base 2 away from the air outlet pipe 11 is used for detachable connection with the heating component 200, so that the liquid storage chamber 12 is connected to the liquid inlet channel 42 of the heating component 200 through the lower liquid hole 22, and the air outlet hole 21 is connected to the mist outlet channel 43 of the heating component 200.

[0070] The first sealing member 3 is provided with a through hole corresponding to the lower liquid hole 22, and the through hole is connected to the lower liquid hole 22, or the first sealing member 3 is provided with a first sealing tube 31 corresponding to the lower liquid hole 22, and the first sealing tube 31 is at least partially embedded in the lower liquid hole 22. Figure 3 and Figure 5 As shown, in this embodiment, the first sealing member 3 is provided with a first sealing tube 31 at a position corresponding to the lower liquid hole 22, and the first sealing tube 31 is embedded in the lower liquid hole 22. The first sealing member 3 also includes a blocking member 33 to block the lower liquid hole 22, wherein the blocking member 33 is configured to open the lower liquid hole 22 when the liquid storage component 100 is connected to the heating component 200, so that the liquid storage chamber 12 is connected to the liquid inlet channel 42 of the heating component 200 through the lower liquid hole 22, thereby realizing the aerosol generation matrix in the liquid storage chamber 12 is transferred to the liquid inlet channel 42 of the heating component 200, so as to facilitate the atomization process.

[0071] In one embodiment, the blocking member 33 can be configured as a sealing plug, which is movably disposed in the lower liquid hole 22, and is used to be moved out of the lower liquid hole 22 when the liquid storage component 100 is connected to the heating component 200, so that the lower liquid hole 22 is opened. Wherein, the sealing plug is made of silicone, rubber or other flexible plastic materials. Specifically, the sealing plug is movably disposed in the first sealing tube 31, and is used to be moved out of the first sealing tube 31 when the liquid storage component 100 is connected to the heating component 200, so that the first sealing tube 31 is opened, and the liquid storage cavity 12 is connected to the liquid inlet channel 42 of the heating component 200. For example, the sealing plug can be movably disposed in the first sealing tube 31 by being embedded, or it can be movably connected to the inner surface of the first sealing tube 31. Wherein, when the sealing plug is movably connected to the inner surface of the first sealing tube 31, it can be integrally formed with the first sealing member 3.

[0072] In another embodiment, the blocking member 33 can be configured as a sealing film, which blocks the port of the lower liquid hole 22. The sealing film is used to be punctured when the liquid storage component 100 is connected to the heating component 200, so that the lower liquid hole 22 is opened. Specifically, the sealing film can be a thin film with a relatively small thickness, which is easily punctured under the action of external force.

In a specific embodiment, the first sealing member 3 is provided with a first sealing tube 31 at a position corresponding to the lower liquid hole 22, and the first sealing tube 31 is embedded in the lower liquid hole 22. The sealing film is arranged in the first sealing tube 31 and connected to the inner surface of the first sealing tube 31, or it can also be connected to the port position of the first sealing tube 31 to block the lower liquid hole 22.

[0073] See also Figure 3 and Figure 5 In this embodiment, the first sealing member 3 includes a cover portion 34, a surrounding portion 35, a first sealing tube 31 and a second sealing tube 32. The cover portion 34 is arranged on a side of the base 2 close to the air outlet pipe 11, and the surrounding portion 35 is arranged around the side wall of the base 2. The first sealing tube 31 is connected to the position of the cover portion 34 corresponding to the lower liquid hole 22 and is embedded in the lower liquid hole 22. A part of the second sealing tube 32 is embedded in the air outlet hole 21, and the other part passes through the cover portion 34 and is sleeved on one end of the air outlet pipe 11, so that the air outlet pipe 11 is connected to the air outlet hole 21. It can be understood that the first sealing tube 31 is arranged at the position of the first sealing member 3 corresponding to the lower liquid hole 22, and the second sealing tube 32 is arranged at the position corresponding to the air outlet hole 21, which can facilitate a tighter assembly connection between the first sealing member 3 and the base 2 and the first shell 1, and also facilitate better sealing and connection with the heating component 200.

[0074] Specifically, the inner surface of the first sealing tube 31 is provided with a first sealing convex ring 311, and / or the inner surface of the second sealing tube 32 is provided with a second sealing convex ring 321. Figure 5As shown, in this embodiment, the inner surface of the first sealing tube 31 is provided with a first sealing convex ring 311, and the height H1 of the first sealing convex ring 311 is within the range of 0.05-2mm. Along the axial direction of the liquid storage component 100, the width D1 of the first sealing convex ring 311 is greater than or equal to the height H1 of the first sealing convex ring 311. Further, the inner surface of the second sealing tube 32 is also provided with a second sealing convex ring 321, and the size of the second sealing convex ring 321 is equal to the size of the first sealing convex ring 311. It can be understood that the first sealing convex ring 311 is provided on the inner surface of the first sealing tube 31, and the size of the first sealing convex ring 311 is set within the above range, so that when the heating component 200 is connected to the liquid storage component 100, the first sealing tube 31 and the structural parts of the heating component 200 can be connected by interference fit to achieve a tighter connection, so as to better seal the connection position of the first sealing tube 31 and the heating component 200, prevent the aerosol generation matrix in the liquid storage chamber 12 from leaking and affecting the performance of the electronic atomization device 400, and avoid waste. Similarly, a second sealing convex ring 321 is provided on the inner surface of the second sealing tube 32, and the size of the second sealing convex ring 321 is set within the above range, so as to realize an interference fit connection between the second sealing tube 32 and the structural parts of the heating component 200, thereby avoiding leakage of airflow or aerosol generated by atomization.

[0075] like Figure 3 As shown, in this embodiment, the base 2 is disposed in the first housing 1, and the end surface of the base 2 away from the outlet pipe 11 can be flush with the open end of the first housing 1, so as to facilitate assembly when the liquid storage component 100 is connected to the power supply component 300. In other embodiments, the end surface of the base 2 away from the outlet pipe 11 can be spaced from the open end of the first housing 1, or the base 2 can be only partially disposed in the first housing 1, as long as it can cooperate with the first housing 1 to form the liquid storage cavity 12 and can ensure that the liquid storage component 100 can be stably connected to the power supply component 300 and the heating component 200.

[0076] For further information, see Figure 4 In this embodiment, a limiting groove 23 is further provided on the surface of the base 2 away from the air outlet pipe 11. The limiting groove 23 is spaced apart from the lower liquid hole 22 and the air outlet hole 21, so that when the liquid storage component 100 is connected to the power supply component 300, the structural parts of the power supply component 300 can be inserted into the limiting groove 23, so as to achieve a more convenient and stable detachable connection between the liquid storage component 100 and the power supply component 300.

When the liquid storage component 100 is detachably connected to the heating component 200, the liquid storage chamber 12 of the liquid storage component 100 is fluidically connected to the liquid inlet port 44 of the liquid inlet channel 42 of the heating component 200 through the lower liquid hole 22, so that the aerosol generating matrix in the liquid storage chamber 12 enters the liquid inlet channel 42 through the liquid inlet port 44 and is absorbed by the liquid absorption surface 52 of the atomizing core 5, and is heated by the atomizing surface 51 to be atomized to generate aerosol, and the aerosol generated by atomization enters the mist outlet channel 43, and enters the air outlet of the liquid storage component 100 through the mist outlet port 45 of the mist outlet channel 43, and then flows through the air outlet pipe 11 and is finally inhaled by the user.

[0080] For details, see Figure 1, Figure 3 , Figure 7 and Figure 8 In this embodiment, one end face of the second housing 4 is connected with a first connecting tube 46 and a second connecting tube 47 spaced apart from each other, and the first connecting tube 46 and the second connecting tube 47 are used to be detachably connected to the liquid storage assembly 100. Specifically, in one embodiment, the first connecting tube 46 and the second connecting tube 47 are parallel to each other, which can facilitate a better and more efficient detachable connection with the liquid storage assembly 100. The first connecting tube 46 is connected to the liquid inlet channel 42, and the second connecting tube 47 is connected to the mist outlet channel 43. The end of the first connecting tube 46 away from the liquid inlet channel 42 serves as the liquid inlet port 44, and the end of the second connecting tube 47 away from the mist outlet channel 43 serves as the mist outlet port 45. The first connecting tube 46 is used to be inserted into the first sealing tube 31 when the heating component 200 is detachably connected to the liquid storage component 100, so that the liquid inlet channel 42 is connected to the lower liquid hole 22, and the second connecting tube 47 is used to be inserted into the air outlet 21 when the heating component 200 is detachably connected to the liquid storage component 100, so that the mist outlet channel 43 is connected to the air outlet 21. By providing the first connecting tube 46 and the second connecting tube 47, the connection with the liquid storage component 100 is directly achieved through the first connecting tube 46 and the second connecting tube 47, and the heating component 200 does not need to be provided with other structural parts for achieving the connection with the liquid storage component 100, which simplifies the structure and can achieve a more convenient and efficient detachable connection between the liquid storage component 100 and the heating component 200.

[0081] In this embodiment, a first sealing convex ring 311 is provided on the inner surface of the first sealing tube 31, a second sealing convex ring 321 is provided on the inner surface of the second sealing tube 32, an outer surface of the first connecting tube 46 is contacted with the first sealing convex ring 311, and an outer surface of the second connecting tube 47 is contacted with the second sealing convex ring 321, thereby realizing an interference fit connection between the liquid storage component 100 and the heating component 200, ensuring the tightness and stability of the connection while further ensuring the sealing effect.

[0082] In this embodiment, the first connecting tube 46 is inserted into the first sealing tube 31, and the first connecting tube 46 pushes the blocking member 33 disposed in the first sealing tube 31 out of the first sealing tube 31, so that the first sealing tube 31 is opened, and the first sealing tube 31 is connected to the liquid inlet 44 at the end of the first connecting tube 46, so that the aerosol generating substrate in the liquid storage chamber 12 flows into the liquid inlet channel 42. In other embodiments, the liquid inlet 44 may also be provided on the side wall of the first connecting tube 46, and after the first connecting tube 46 is inserted into the first sealing tube 31, the first connecting tube 46 protrudes from the end of the first sealing tube 31, and the liquid inlet 44 extends into the liquid storage chamber 12, and the aerosol generating substrate in the liquid storage chamber 12 directly enters the liquid inlet channel 42 through the liquid inlet 44 on the side wall of the first connecting tube 46 to be absorbed.

[0083] Preferably, the first connecting tube 46 is coaxially arranged with the liquid inlet channel 42, and more preferably, the inner wall surface of the first connecting tube 46 is flush with the inner wall surface of the liquid inlet channel 42; and / or, the second connecting tube 47 is coaxially arranged with the mist outlet channel 43, and the inner wall surface of the second connecting tube 47 is flush with the inner wall surface of the mist outlet channel 43. It can be understood that the first connecting tube 46 is coaxially arranged with the liquid inlet channel 42, and the inner wall surface of the first connecting tube 46 is flush with the inner wall surface of the liquid inlet channel 42, and the second connecting tube 47 is coaxially arranged with the mist outlet channel 43, and the inner wall surface of the second connecting tube 47 is flush with the inner wall surface of the mist outlet channel 43. This can ensure that the aerosol-generating matrix flowing through the liquid inlet 44, i.e., the port of the first connecting tube 46, can flow more smoothly into the liquid inlet channel 42 and be absorbed by the atomization core 5 to ensure smooth liquid flow, which is beneficial to improving the atomization efficiency. At the same time, the aerosol generated by atomization in the mist outlet channel 43 can also flow more smoothly to the mist outlet 45, which is beneficial to improving the user experience.

[0084] like Figure 7 and Figure 8 As shown, the other end of the second housing 4 of the heating component 200 away from the mist outlet 45 has an air inlet 48, which is used to communicate with the mist outlet channel 43 to input external air into the mist outlet channel 43 and enter the air outlet pipe 11 together with the aerosol generated by atomization. The air inlet 48 can be coaxially arranged with the mist outlet channel 43, or non-coaxially arranged, as long as the fluid communication between the air inlet 48 and the mist outlet channel 43 is achieved.

[0085] Further, in this embodiment, if Figure 8 As shown, the second housing 4 includes a first sub-housing 401 and a second sub-housing 402 connected to each other, the interior of the first sub-housing 401 has an atomizing groove 41 and a liquid inlet channel 42, and the interior of the second sub-housing 402 has a mist outlet channel 43. The surface of the first sub-housing 401 close to the second sub-housing 402 is provided with an annular groove, and the surface of the second sub-housing 402 close to the first sub-housing 401 is provided with an annular protrusion, and the annular protrusion is embedded in the annular groove to cooperate with the formation of the mutually connected mist outlet channel 43, the atomizing groove 41 and the liquid inlet channel 42. Specifically, the first connecting pipe 46 is connected to the end face of one end of the first sub-housing 401 so that the liquid inlet 44 is connected to the liquid inlet channel 42, and the second connecting pipe 47 is connected to the end face of one end of the second sub-housing 402 so that the mist outlet 45 is connected to the mist outlet channel 43. It can be understood that the second housing 4 is set to include the first sub-housing 401 and the second sub-housing 402, which can make it easier to assemble the atomizing core 5 and the second sealing member 6 into the second housing 4, and the assembly method is simpler. In other implementations, the second housing 4 may not include the first sub-housing 401 and the second sub-housing 402 , and the second housing 4 may be provided as a separate structural component.

[0086] See also Figures 10 to 12 The atomizing core 5 includes a porous liquid-conducting substrate 53 and a heating element 54. The porous liquid-conducting substrate 53 can be made of porous materials such as porous ceramics, porous glass, and porous metal, or can also be made of dense materials to form a porous structure by punching holes. Fig.11 As shown, the porous liquid-conducting substrate 53 is roughly in the shape of a rectangular parallelepiped, and a receiving groove 531 is provided on one surface of the porous liquid-conducting substrate 53. The heating element 54 is arranged in the receiving groove 531 of the porous liquid-conducting substrate 53. Specifically, a plurality of protrusions are provided on the bottom surface of the receiving groove 531, and a plurality of holes are provided on the heating element 54 corresponding to the plurality of protrusions. The plurality of protrusions of the receiving groove 531 are embedded in the plurality of holes one by one to realize the fixed connection between the porous liquid-conducting substrate 53 and the heating element 54.

[0087] In this embodiment, the heating element 54 is an electromagnetic induction element, which generates heat by electromagnetic induction so that the atomizing core 5 heats the atomized aerosol to generate the matrix to generate aerosol. In other embodiments, the heating element 54 may also be directly buried inside the porous liquid-conducting matrix 53, and generate heat by electromagnetic induction, thereby heating the atomized aerosol to generate the matrix. It can be understood that the heating element 54 generates heat by electromagnetic induction, and generates heat by inducing an external magnetic field and exciting an induced current inside it to heat the aerosol to generate the matrix. It does not need to be electrically connected to the power supply assembly 300, which avoids the problem of poor contact between the heating element 54 and the power supply assembly 300 and affecting the atomization performance, which is beneficial to improving the performance of the electronic atomization device 400. In other embodiments, the heating element 54 may not be set as an electromagnetic induction element, and may be directly electrically connected to the power supply assembly 300 to generate heat by resistive heating.

[0089] See also Figure 1 , Fig.13 and Fig.14In this embodiment, the power supply component 300 is detachably connected to the liquid storage component 100 and the heating component 200. The power supply component 300 includes a third shell 7. The third shell 7 has a housing chamber 71 inside. One end of the heating component 200 can be accommodated in the housing chamber 71.

Specifically, the heating element 54 of the atomizer core 5 is disposed in the housing chamber 71, and the heating element 54 of the atomizer core 5 generates heat by electromagnetic induction. The power supply component 300 also includes an electromagnetic coil 8 and a battery 81. The third shell 7 also has an installation chamber 72 inside.

Specifically, the electromagnetic coil 8 is arranged corresponding to the heating element 54 and is wound around the outer side of the accommodating cavity 71. The electromagnetic coil 8 is electrically connected to the battery 81, so that when the electromagnetic coil 8 is powered on, the heating element 54 can generate heat by electromagnetic induction, thereby heating the atomized aerosol to generate the matrix, effectively avoiding the problem that when the heating element 54 generates heat by resistance, the battery 81 of the power supply assembly 300 and the heating element 54 are electrically connected by contact, resulting in poor contact between the battery 81 and the heating element 54, affecting the atomization performance. In other embodiments, the installation cavity 72 can also be arranged at intervals on the side of the accommodating cavity 71, and the electromagnetic coil 8 can also be arranged corresponding to the heating element 54 and wound around the inner side of the accommodating cavity 71, so that the heating element 54 generates heat by electromagnetic induction.

When the end of the liquid storage assembly 100 close to the power assembly 300 is inserted into the assembly groove 73, the limiting column 74 is arranged in the limiting groove 23, so that the power assembly 300 and the liquid storage assembly 100 are detachably connected, so that the connection between the liquid storage assembly 100 and the power assembly 300 is more stable and the assembly efficiency is higher.

[0092] The present application also provides another electronic atomization device 400, which is different from the first embodiment of the electronic atomization device 400 in that, in this embodiment, Fig.16 , Fig.17 and Fig. 20 As shown, the end face of the base 2 of the liquid storage component 100 away from the end of the air outlet pipe 11 is spaced from the end face of the open end of the first shell 1, and a mounting groove 13 is also provided inside the first shell 1. The second shell 4 of the heating component 200 is not provided with the first connecting pipe 46 and the second connecting pipe 47, and one end of the second shell 4 is at least partially embedded in the mounting groove 13, so that the heating component 200 and the liquid storage component 100 can be detachably connected. Specifically, a mounting seat 49 is connected to one end of the second shell 4, and the size of the mounting seat 49 is adapted to the size of the mounting groove 13. By installing the mounting seat 49 in the mounting groove 13 of the liquid storage component 100, the liquid storage component 100 and the heating component 200 can be detachably connected, and a more convenient assembly connection is achieved.

[0093] Specifically, Fig.17 and Fig.18 As shown, in this embodiment, the first sealing member 3 does not include the first sealing tube 31, and the position of the first sealing member 3 corresponding to the lower liquid hole 22 is set as a through hole, and the blocking member 33 can be directly and movably set in the through hole or the lower liquid hole 22. In one embodiment, the blocking member 33 is a sealing plug, which can be movably set in the lower liquid hole 22 by embedding, or can be movably connected to the hole wall of the through hole of the first sealing member 3 to block the lower liquid hole 22, and when the liquid storage component 100 and the heating component 200 are detachably connected, the sealing plug is moved out of the lower liquid hole 22 under the external force of the structure of the heating component 200, so that the lower liquid hole 22 is opened. Among them, when the sealing plug is movably connected to the hole wall of the through hole of the first sealing member 3, it can be integrally formed with the first sealing member 3.

[0094] In another embodiment, the blocking member 33 is a sealing film, and the position of the first sealing member 3 corresponding to the lower liquid hole 22 is set as a through hole. The sealing film is directly connected to the hole wall of the through hole of the first sealing member 3 and blocks the lower liquid hole 22. When the liquid storage component 100 and the heating component 200 are detachably connected, the sealing film is punctured under the external force of the structure of the heating component 200, the lower liquid hole 22 is opened, and the liquid storage chamber 12 is connected with the liquid inlet channel 42 of the heating component 200 through the lower liquid hole 22.

[0095] In this embodiment, the base 2 is completely disposed in the first housing 1, and the surface of the base 2 at one end away from the air outlet pipe 11 is spaced apart from the end surface of the open end of the first housing 1 to form a mounting groove 13. Fig.16 , Fig.17 ,and Fig. 20 As shown, specifically, the mounting seat 49 is provided with a liquid inlet 44 at a position corresponding to the liquid inlet channel 42, and the liquid inlet 44 is connected to the liquid inlet channel 42. The end face of the mounting seat 49 away from the liquid inlet channel 42 is connected with a support member 491, and the support member 491 is provided corresponding to the lower liquid hole 22. The mounting seat 49 is provided with a mist outlet 45 at a position corresponding to the mist outlet channel 43. When the liquid storage component 100 and the heating component 200 are detachably connected, the mounting seat 49 is installed in the mounting groove 13 of the liquid storage component 100, and the liquid inlet 44 corresponds to the lower liquid hole 22. The support member 491 presses against the blocking member 33 of the liquid storage component 100, and moves the blocking member 33 out of the lower liquid hole 22. The lower liquid hole 22 is opened, so that the liquid storage cavity 12 is connected to the liquid inlet channel 42 through the lower liquid hole 22 and the liquid inlet 44, and the mist outlet 45 is connected to the air outlet pipe 11 and the mist outlet channel 43.

[0096] In this embodiment, the second housing 4 of the heating component 200 is a separate structural member, and does not include the first sub-housing 401 and the second sub-housing 402. The second sealing member 6 is partially arranged around the side wall of the atomizing core 5 and separates the liquid inlet channel 42 from the mist outlet channel 43, and partially extends to the side of the mounting seat 49 close to the liquid storage component 100. The second sealing member 6 is located on the side of the mounting seat 49 close to the liquid storage component 100. The portion of the second sealing member 6 corresponding to the air outlet hole 21 and the lower liquid hole 22 is respectively provided with openings to connect the lower liquid hole 22 with the liquid inlet channel 42, and the air outlet hole 21 is connected with the mist outlet channel 43. Further, the portion of the second sealing member 6 corresponding to the lower liquid hole 22 is embedded in the lower liquid hole 22, so that the heating component 200 and the liquid storage component 100 are assembled more tightly, which is more conducive to preventing the leakage of the aerosol generating matrix in the liquid storage cavity 12. The end of the second housing 4 of the heating component 200 away from the liquid storage component 100 can still be accommodated in the accommodating cavity 71 of the power supply component 300.

[0097] See also Fig.16 and Fig.17In this embodiment, the installation cavity 72 is not arranged at the bottom of the accommodating cavity 71.

By directly embedding one end of the liquid storage component 100 in the assembly groove 73, the detachable connection between the liquid storage component 100 and the power supply component 300 is realized.

[0098] In this embodiment, the remaining structures are the same as those in the first embodiment of the electronic atomization device 400 and will not be described in detail.

[0099] See also Figure 21 to Figure 25 , Fig.21 is a cross-sectional schematic diagram of an implementation of a liquid storage component of the third embodiment of the electronic atomization device provided by the present application, Fig. 22 yes Fig.21 A schematic diagram of the structure of the base of the liquid storage assembly is provided, Fig.23 yes Fig.21 A schematic diagram of the structure of the active components of the liquid storage component is provided, Fig.24 yes Fig.21 A schematic cross-sectional view of a first sealing member of a liquid storage assembly is provided, Fig.25 It is a structural schematic diagram of an implementation scheme of a power supply component of the third embodiment of the electronic atomization device provided in the present application.

[0100] The present application also provides another electronic atomization device 400, which is different from the first embodiment of the electronic atomization device 400 in that, in this embodiment, the liquid storage component 100 of the electronic atomization device 400 also includes a movable component 9, which is arranged in the first housing 1 and is located on the side of the base 2 close to the air outlet pipe 11, and one end of the movable component 9 is configured to be able to move between a first position and a second position relative to the base 2. When one end of the movable component 9 is in the first position, the lower liquid hole 22 is blocked; when one end of the movable component 9 is in the second position, the lower liquid hole 22 is opened so that the lower liquid hole 22 is connected to the liquid storage chamber 12. By providing the movable component 9, the lower liquid hole 22 of the liquid storage component 100 can be blocked or opened when one end of the movable component 9 moves between the first position and the second position relative to the base 2, which is conducive to solving the problem of leakage of the aerosol generation matrix.

[0101] In this embodiment, the movable assembly 9 includes a movable member 91 and an elastic arm 92. The movable member 91 is rotatably connected to the base 2 so that one end of the movable member 91 can move between a first position and a second position. The elastic arm 92 is fixedly connected to the movable member 91. The elastic arm 92 is used to provide a driving force for the movable member 91 when the movable member 91 is in the second position so that the movable member 91 can be reset to the first position to re-block the lower liquid hole 22.

[0102] For details, see Fig.21 , Fig. 22 and Fig.23 In this embodiment, the base 2 includes a main body 24 and a fixed portion 25 connected to the main body 24 on a side close to the air outlet pipe 11. The main body 24 has a lower liquid hole 22 and an air outlet 21 that are spaced apart from each other. The movable member 91 includes a base 93 that is arranged around the air outlet 21. A protrusion 94 is connected to a first end of the base 93, and a rotating member 95 is connected to a second end opposite to the first end. The protrusion 94 can switch between a first position and a second position to block or open the lower liquid hole 22. One of the fixed portion 25 and the rotating member 95 has a rotating shaft 96, and the other has a bearing hole 97. The rotating shaft 96 is rotatably arranged in the bearing hole 97, so that the fixed portion 25 and the rotating member 95 can be rotatably connected. As shown Fig. 22 As shown, in this embodiment, two mutually spaced fixed parts 25 are connected to one side of the main body 24 of the base 2 close to the air outlet pipe 11, and two rotating parts 95 are connected to the second end of the movable part 91. The rotating part 95 has a rotating shaft 96, and the fixed part 25 has a bearing hole 97. The rotating shafts 96 of the two rotating parts 95 are rotatably arranged in the bearing holes 97 of the two fixed parts 25 in a one-to-one correspondence. In other embodiments, only one fixed part 25 and rotating part 95 may be provided, or the rotating shaft 96 may be provided on the fixed part 25, and the bearing hole 97 may be provided on the rotating part 95, as long as the rotating connection between the rotating part 95 and the fixed part 25 can be realized so that the protruding column 94 at one end of the movable part 91 can be switched between the first position and the second position.

[0103] In this embodiment, the rotating member 95 is an arc-shaped structure, the elastic arm 92 is an arc-shaped structure, one end of the elastic arm 92 is in contact with the main body 24, and the other end is connected to the base 93 or the rotating member 95. The elastic arm 92 is an elastic mechanism. Fig. 22As shown, in one embodiment, there is one elastic arm 92, which is located between two rotating members 95 and spaced apart from the rotating members 95. One end of the elastic arm 92 abuts against the main body 24, and the other end is connected to the second end of the base 93. The first end of the boss 94 of the movable member 91 switches from the first position to the second position through the rotation shaft 96 of the rotating member 95 rotating in the bearing hole 97. When the first end of the boss 94 of the movable member 91 is in the second position, the main body 24 of the base 2 squeezes the elastic arm 92, and the elastic arm 92 is in a compressed state. The elastic force of the elastic arm 92 is greater. The compressed elastic arm 92 causes the movable member 91 to generate a rotational torque based on the rotation shaft 96, providing a driving force for the movable member 91, so that the boss 94 at the first end of the base 93 of the movable member 91 can be reset to the first position and the lower liquid hole 22 can be re-blocked. The elastic arm 92 can be integrally formed with the base 93.

[0104] In other embodiments, the rotating member 95 may be configured in other shapes, the number of the elastic arms 92 may be configured in other numbers such as two or three, and the other end of the elastic arm 92 may be directly connected to the rotating member 95. The elastic arm 92 is compressed by the rotation of the rotating member 95, thereby providing a driving force for the boss 94 of the movable member 91 to reset to the first position. The movable assembly 9 may not be provided with the elastic arm 92, and other elastic mechanisms may be used to provide a driving force for the boss 94 of the movable member 91 to reset to the first position. For example, a spring or other structure may be directly arranged in the liquid storage chamber 12, one end of the spring is connected to the inner surface of the first housing 1, and the other end is connected to the first end of the base 93 of the movable member 91. When the spring is in the first state, the boss 94 at the first end of the base 93 is in the first position, and the lower liquid hole 22 is blocked. When the spring is in the second state, the boss 94 at the first end of the base 93 is in the second position, and the lower liquid hole 22 is opened. When the boss 94 at the first end of the base 93 is in the second position, the spring is in a compressed state, providing elastic force for the movable member 91. The boss 94 at the first end of the base 93 can be reset to the first position under the elastic force of the spring, thereby re-blocking the lower liquid hole 22. Alternatively, other elastic mechanisms may be used, as long as the boss 94 of the movable member 91 can be provided with a driving force to reset to the first position.

[0105] See also Fig.21 and Fig.23 In this embodiment, the movable component 9 further includes a sealing sleeve 98, which is sleeved on the convex column 94 and is made of a flexible sealing material such as rubber or silicone. By sleeved on the outer surface of the convex column 94, the lower liquid hole 22 can be better sealed, so that the sealing between the sealing sleeve 98 and the lower liquid hole 22 is more reliable, which is more conducive to preventing the leakage of the aerosol generating matrix in the liquid storage chamber 12.

[0106] like Fig.24 As shown, in this embodiment, the first sealing member 3 includes a surrounding portion 35 and a cover portion 34 connected to each other, the cover portion 34 is arranged on a side of the main body portion 24 of the base 2 close to the air outlet pipe 11, and the surrounding portion 35 is arranged around the side wall of the main body portion 24. The main body portion 24 of the base 2 has a avoidance hole 26 corresponding to the base 93, and the cover portion 34 includes a deformation portion 342 covering the avoidance hole 26. The avoidance hole 26 is used to allow other components to pass through the avoidance hole 26 and push the base 93 through the deformation portion 342, so that one end of the movable member 91 is switched from the first position to the second position.

[0107] Specifically, the cover portion 34 includes a cover body 341 and a deformation portion 342. The cover body 341 has an opening corresponding to the avoidance hole 26. The deformation portion 342 includes a bottom wall and an annular side wall. The bottom wall is arranged in the opening and is spaced apart from the inner wall surface of the opening. One end of the annular side wall is connected to the inner wall surface of the opening, and the other end is connected to the edge of the bottom wall, so that the deformation portion 342 can be easily deformed under the action of external force. Fig.21 and Fig.23 , a protrusion 931 is provided on the surface of the base 93 close to the main body 24.
