[0040] like Figure 1 and Figure 2 As shown, an embodiment provides an atomizing device, including a housing assembly 100, an atomizing component 200, and a liquid storage cup 300. The housing assembly 100 includes a housing 110 and a drive component 120, the drive component 120 being movably mounted within the housing 110, with a portion of the drive component 120 exposed relative to the housing 110. Accordingly, a user can directly access the portion of the drive component 120 exposed relative to the housing 110.

[0041] In some embodiments, the atomizing component 200 is disposed within the housing component 100. A liquid reservoir 300 is slidably disposed within the housing component 100 and surrounds the atomizing component 200, with the sliding direction of the liquid reservoir 300 parallel to the axial direction of the atomizing component 200. In some embodiments, the axial direction of the atomizing component 200 may be parallel to the axial direction of the atomizing device, which may refer to the extension direction of the central axis L of the atomizing device. Furthermore, the liquid reservoir 300 is configured with a plurality of liquid storage chambers 330 sequentially arranged along the axial direction of the atomizing component 200. In these embodiments, different liquid storage chambers 330 can be used to store atomizing bases of different flavors.

[0042] In some embodiments, the axial direction of the atomizing component 200 may also be perpendicular to the axial direction of the atomizing device.

[0043] In some embodiments, the same atomizing matrix may be stored in different liquid storage chambers 330.

[0044] In some embodiments, the drive member 120 can be driven to the liquid reservoir 300, and the drive member 120 can be configured to drive the liquid reservoir 300 to slide along the axial direction of the atomizing assembly 200, so that at least one liquid reservoir 330 forms a liquid path connection with the atomizing assembly 200. During use, the user can drive the liquid reservoir 300 to move along the axial direction of the atomizing assembly 200 through the drive member 120, so that at least one liquid reservoir 330 forms a liquid path connection with the atomizing assembly 200, thereby enabling the switching of different flavor atomizing substrates. The liquid reservoir 330, which forms a liquid path connection with the atomizing assembly 200, can supply the atomizing substrate to the atomizing assembly 200, and the atomizing assembly 200 heats and atomizes the received atomizing substrate to generate an aerosol for the user to inhale.

[0045] In the atomizing device provided in this embodiment, multiple liquid storage chambers 330 can share the same set of atomizing components 200. The atomizing device can provide a variety of flavored aerosols while reducing the number of atomizing components 200, thus lowering the production cost. Furthermore, the atomizing device provided in this embodiment also includes a drive component 120 that is connected to the liquid storage cup 300. A portion of the drive component 120 is exposed outside the outer casing 110, allowing the user easy access to the drive component 120. This allows the drive component 120 to drive the liquid storage cup 300 to move axially along the atomizing component 200, enabling the switching of different flavored aerosols, facilitating user operation, and improving user convenience.

[0046] like Figure 1 and Figure 2As shown, in some embodiments, the atomizing device further includes a mouthpiece assembly 550, which can be connected to one end of the housing 110. In some embodiments, the mouthpiece assembly 550 may include a mouthpiece 400, which may include an integral mouthpiece body 410 and an air guide tube 420. One end of the mouthpiece body 410 is inserted into the housing 110 and can be connected to the housing 110 by means of snap-fit ​​connection, interference fit, or adhesive bonding, which can prevent the mouthpiece 400 from falling off the housing 110 at will. The other end of the mouthpiece body 410 may protrude relative to the housing 110 and form an output port 430. The air guide tube 420 may be disposed in the mouthpiece body 410, and the air guide tube 420 may be connected to the end of the mouthpiece body 410 near the output port 430, and the air guide tube 420 may be in communication with the output port 430. The end of the air duct 420 away from the output port 430 can extend into the housing 110 and communicate with the atomizing component 200.

[0047] In some embodiments, the mouthpiece assembly 550 further includes a second seal 511. The second seal 511 is insertable into the end of the mouthpiece body 410 away from the outlet 430 and seals against the inner wall of the mouthpiece body 410 facing the air guide tube 420. One end of the atomizing assembly 200 may pass through the second seal 511 and be exposed relative to the side of the second seal 511 facing the air guide tube 420, so that the atomizing assembly 200 communicates with the end of the air guide tube 420 away from the outlet 430.

[0048] In some embodiments, the nozzle assembly 550 further includes a first liquid-absorbing member 521, which may be disposed on the side of the second seal 511 facing the air guide tube 420. The first liquid-absorbing member 521 can be used to absorb and store condensate generated at the location of the nozzle 400, reducing the possibility of leakage from the atomizing device. In an embodiment, the first liquid-absorbing member 521 has a first through hole 5211, which can penetrate the first liquid-absorbing member 521 along the axial direction of the atomizing device and can communicate between the air guide tube 420 and the atomizing assembly 200. In some embodiments, the first liquid-absorbing member 521 may be made of a structure such as absorbent cotton.

[0049] like Figure 2 and Figure 3As shown, in some embodiments, the atomizing assembly 200 may include an atomizing tube 210 and an atomizing core 220. The atomizing tube 210 may extend axially along the atomizing device. One end of the atomizing tube 210 is inserted into the second sealing member 511 and communicates with the end of the air guide tube 420 away from the output port 430. The atomizing core 220 may be fixedly disposed in the atomizing tube 210 and located approximately at the middle of the axial direction of the atomizing tube 210. Additionally, the atomizing tube 210 may have a liquid inlet hole 211 that is opposite to and communicates with the atomizing core 220. The atomizing matrix in the liquid storage chamber 330 can enter the atomizing core 220 through the liquid inlet hole 211, and the atomizing core 220 heats and atomizes the atomizing matrix to generate an aerosol. The aerosol can sequentially pass through the atomizing tube 210, the first through hole 5211, and the air guide tube 420, and be output from the output port 430 of the mouthpiece 400.

[0050] In some embodiments, a plurality of liquid inlet holes 211 may be provided on the periphery of the atomizing tube 210. These liquid inlet holes 211 may be distributed around the periphery of the atomizing tube 210 and are at the same height in the axial direction of the atomizing assembly 200. That is, the distances between the plurality of liquid inlet holes 211 and the end face of the atomizing tube 210 facing the nozzle 400 are all equal. Accordingly, when the liquid storage cup 300 is moved into position relative to the atomizing assembly 200, a liquid storage chamber 330 can be connected to the atomizing assembly 200 through the liquid inlet holes 211 to form a liquid path.

[0051] In some embodiments, the plurality of liquid inlet holes 211 may be distributed at different height positions along the axial direction of the atomizing tube 210 along the atomizing assembly 200, that is, the distance between the plurality of liquid inlet holes 211 and the end face of the atomizing tube 210 facing the nozzle 400 is not equal. When the liquid storage cup 300 moves into position relative to the atomizing assembly 200, two or three equal numbers of liquid storage chambers 330 can form a liquid path communication with the atomizing assembly 200 through the liquid inlet holes 211 in relative positions.

[0052] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, the liquid reservoir 300 may include a housing assembly 310 and a partition assembly 320. The housing assembly 310 includes a housing 311, a first end cap 312, and a second end cap 313. The housing 311 may be a cylindrical structure with openings at both ends and is disposed around the periphery of the atomizing assembly 200. In this embodiment, the first end cap 312 may cover the opening of the housing 311 facing the nozzle 400 and may be connected to the outer shell 110 by means of snap-fit ​​connection, bonding, or interference fit. Accordingly, the opening of the housing 311 facing the nozzle 400 may be closed by the first end cap 312. The second end cap 313 may cover the opening of the housing 311 away from the nozzle 400 and may be connected to the housing 311 by means of snap-fit ​​connection, bonding, or interference fit. Accordingly, the opening of the housing 311 away from the nozzle 400 is closed by the second end cap 313.

[0053] In some embodiments, the first end cap 312 facing the housing 311 and the second end cap 313 facing the housing 311 are both provided with annular flanges 314. The flanges 314 can seal against the inner wall of the housing 311 facing the liquid storage cavity 330, thereby achieving a seal at the connection between the first end cap 312, the second end cap 313 and the housing 311, reducing the probability of leakage.

[0054] In this embodiment, the atomizing component 200 can be inserted through the first end cap 312 and the second end cap 313, and both the first end cap 312 and the second end cap 313 can slide relative to the atomizing component 200. In some embodiments, an annular third sealing member 315 is provided on the side of the first end cap 312 facing the atomizing component 200 and the side of the second end cap 313 facing the atomizing component 200. The side of the third sealing member 315 away from the first end cap 312 / second end cap 313 seals against the atomizing component 200, that is, the third sealing member 315 seals against the atomizing component 200 and the first end cap 312 / second end cap 313, thereby achieving a seal at the connection position between the first end cap 312 / second end cap 313 and the atomizing component 200.

[0055] In some embodiments, the third seal 315 has an annular second insertion groove 3151 on the side opposite to the atomizing assembly 200, and the opening of the second insertion groove 3151 may be disposed on the side opposite to the atomizing assembly 200. The first end cap 312 and the second end cap 313 both have annular second insertion portions 3121 protruding from the side facing the atomizing assembly 200. The second insertion portions 3121 can be inserted into the second insertion groove 3151 on the third seal 315 at the opposite position and seal against the inner wall of the second insertion groove 3151. Thus, the third seal 315 and the first end cap 312 / second end cap 313 can form a limiting connection in the sliding direction of the liquid storage cup 300 (i.e., the axial direction of the atomizing assembly 200). When the liquid storage cup 300 slides relative to the atomizing assembly 200, the third seal 315 can be prevented from disengaging from the first end cap 312 / second end cap 313, ensuring the sealing of the connection position between the atomizing assembly 200 and the first end cap 312 / second end cap 313.

[0056] In some embodiments, an annular groove may be formed on the side of the first end cap 312 / second end cap 313 facing the atomizing assembly 200. The end of the third seal 315 facing the first end cap 312 / second end cap 313 may be embedded in the groove. The end of the third seal 315 facing the atomizing assembly 200 may protrude relative to the groove and seal against the atomizing assembly 200.

[0057] In this embodiment, the side of the third seal 315 facing away from the first end cap 312 / second end cap 313 can seal against the surface of the atomizing tube 210 facing away from the atomizing core 220, and the third seal 315 can slide relative to the atomizing tube 210 along the axial direction of the atomizing assembly 200. In some embodiments, at least one second sealing protrusion 3152 is provided on the side of the third seal 315 facing the atomizing assembly 200, and the second sealing protrusion 3152 can be annular. The second sealing protrusion 3152 can seal against the surface of the atomizing tube 210 facing away from the atomizing core 220. On the one hand, this can prevent leakage; on the other hand, when the liquid storage cup 300 slides relative to the atomizing assembly 200, the second sealing protrusion 3152 can scrape off the atomizing matrix attached to the surface of the atomizing tube 210 facing away from the atomizing core 220, preventing cross-contamination of the atomizing matrix in each liquid storage chamber 330.

[0058] In some embodiments, the third seal 315 may be provided with a second sealing protrusion 3152 protruding from the side facing the atomizing assembly 200.

[0059] In some embodiments, the third seal 315 may have two, three, or four or more second sealing protrusions 3152 protruding from the side facing the atomizing assembly 200. The multiple second sealing protrusions 3152 may be arranged sequentially along the axial direction of the atomizing assembly 200, and all of them shall be in sealing contact with the surface of the atomizing tube 210 away from the atomizing core 220.

[0060] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the partition assembly 320 may protrude from the inner wall of the housing 311 on the side facing the atomizing assembly 200, and divide the internal space of the housing assembly 310 into a plurality of liquid storage chambers 330.

[0061] In some embodiments, the liquid storage cup 300 may include three sets of partition assemblies 320, which are arranged sequentially and spaced apart in the housing assembly 310 along the axial direction of the atomizing assembly 200, and divide the interior of the housing assembly 310 into four liquid storage chambers 330 arranged sequentially along the axial direction of the atomizing assembly 200.

[0062] In some embodiments, the liquid storage cup 300 may also include one, two, or four sets of partition assemblies 320, which divide the interior of the housing assembly 310 into two, three, or five corresponding liquid storage chambers 330. The multiple liquid storage chambers 330 may be arranged sequentially along the axial direction of the atomizing assembly 200.

[0063] In some embodiments, the side of the partition assembly 320 facing the atomizing assembly 200 can seal against the surface of the atomizing tube 210 opposite to the atomizing core 220. In some embodiments, the partition assembly 320 includes a partition 321 and a first sealing member 322. The partition 321 may protrude from the inner wall of the housing 311 facing the atomizing assembly 200 and may have an annular plate structure. In some embodiments, the partition 321 and the housing 311 may be an integral structure.

[0064] In some embodiments, the partition 321 and the housing 311 may also be separate structures. A sealing ring 340 may be abutted between the partition 321 and the housing 311. On the one hand, this can seal the connection position between the partition 321 and the housing 311. On the other hand, it can also keep the partition 321 fixed relative to the housing 311.

[0065] In some embodiments, the liquid reservoir 300 may include three sets of baffle assemblies 320. The baffle 321 located in the middle along the axial direction of the atomizing device may be integrally formed with the housing 311. One baffle 321 near the first end cap 312 and another baffle 321 near the second end cap 313 are separate from the housing 311. Two second stepped surfaces 3111 are also disposed on the side of the housing 311 facing the atomizing assembly 200. One second stepped surface 3111 may be disposed opposite to the first end cap 312, and the other second stepped surface 3111 may be disposed opposite to the second end cap 313. The baffle 321 near the first end cap 312 may be placed on the second stepped surface 3111 opposite to the first end cap 312, and the second stepped surface 3111 provides support and restraint for the baffle 321. The partition 321 near the second end cap 313 can be placed on the second step surface 3111 opposite to the second end cap 313, and the second step surface 3111 provides support and limit for the partition 321.

[0066] In some embodiments, the first sealing member 322 may be disposed on the side of the partition 321 facing the atomizing assembly 200, and sealingly abut against the partition 321 and the atomizing assembly 200. In some embodiments, the first sealing member 322 has an annular first insertion groove 3221 on the side facing the partition 321. The partition 321 has a first insertion portion 3211 protruding from the side facing the atomizing assembly 200. The first insertion portion 3211 can be inserted into the first insertion groove 3221 and sealingly abut against the inner wall of the first insertion groove 3221. Thus, the first sealing member 322 and the partition 321 can form a limiting connection in the sliding direction of the liquid storage cup 300 (i.e., the axial direction of the atomizing assembly 200). When the liquid storage cup 300 slides relative to the atomizing assembly 200, the first sealing member 322 can be prevented from disengaging from the partition 321, ensuring the sealing of the connection position between the atomizing assembly 200 and the partition assembly 320.

[0067] In some embodiments, the partition 321 may have an annular groove on the side facing the atomizing assembly 200. The end of the first seal 322 facing the partition 321 may be embedded in the groove. The end of the first seal 322 facing the atomizing assembly 200 may protrude relative to the groove and seal against the surface of the atomizing tube 210 away from the atomizing core 220.

[0068] In this embodiment, the side of the first sealing member 322 facing away from the partition plate 321 can seal against the surface of the atomizing tube 210 facing away from the atomizing core 220, and the first sealing member 322 can slide relative to the atomizing tube 210 along the axial direction of the atomizing assembly 200. In some embodiments, the first sealing member 322 has at least one first sealing protrusion 3222 protruding from the side facing the atomizing assembly 200, and the first sealing protrusion 3222 can be annular. The first sealing protrusion 3222 can seal against the surface of the atomizing tube 210 facing away from the atomizing core 220. On the one hand, this can prevent leakage; on the other hand, when the liquid storage cup 300 slides relative to the atomizing assembly 200, the first sealing protrusion 3222 can scrape off the atomizing matrix attached to the surface of the atomizing tube 210 facing away from the atomizing core 220, preventing cross-contamination of the atomizing matrix in each liquid storage chamber 330.

[0069] In some embodiments, the first seal 322 may have a first sealing protrusion 3222 protruding from the side facing the atomizing assembly 200.

[0070] In some embodiments, the first seal 322 may have two, three, or four or more first sealing protrusions 3222 protruding from the side of the atomizing assembly 200. The multiple first sealing protrusions 3222 may be arranged sequentially along the axial direction of the atomizing assembly 200, and all of them shall be in sealing contact with the surface of the atomizing tube 210 away from the atomizing core 220.

[0071] like Figure 5 As shown, in some embodiments, each liquid storage chamber 330 is provided with a liquid storage element 350, which can be used to adsorb the atomized matrix. In the embodiments, the liquid storage element 350 may be a structure such as liquid storage cotton.

[0072] like Figures 2 to 6 As shown, in some embodiments, the drive member 120 is rotatably mounted in the housing 110. The drive member 120 may include an integral drive member body 127 and a support plate portion 125. The drive member body 127 may be a cylindrical structure with openings at both ends. The support plate portion 125 may be disposed within the drive member body 127, dividing the drive member body 127 into a first receiving cavity 1271 and a second receiving cavity 1272. In some embodiments, the end of the housing 110 facing away from the suction nozzle 400 may also be configured as an opening, and the end of the drive member body 127 away from the suction nozzle 400 may protrude relative to the end of the housing 110 away from the suction nozzle 400. Accordingly, the end of the drive member body 127 away from the suction nozzle 400 may be exposed relative to the housing 110, facilitating user access to the drive member 120 to allow the drive member 120 to rotate relative to the housing 110. The end of the drive member body 127 facing the suction nozzle 400 may abut against the suction nozzle 400 and the second sealing member 511.

[0073] In some embodiments, a snap-fit ​​protrusion 121 may be provided on the side of the drive body 127 facing the housing 110. A slot 113 is formed on the inner wall of the side of the housing 110 facing the drive body 127, which engages with the snap-fit ​​protrusion 121. The slot 113 may be arranged around the rotation axis of the drive member 120, and correspondingly, the slot 113 may be annular. In this embodiment, the snap-fit ​​protrusion 121 snaps into the slot 113 and may be located within the slot 113 at the upper axial limit of the atomizing device. This allows for axial positioning of the drive member 120 and the housing 110, restricting the drive member 120 from moving relative to the housing 110 along the axial direction of the housing 110, preventing the drive member 120 from arbitrarily detaching from the housing 110, and simultaneously improving the stability of the drive member 120 when rotating relative to the housing 110.

[0074] In some embodiments, an annular slot 113 may be formed on the side of the drive body 127 facing the housing 110. A snap-fit ​​protrusion 121 may protrude from the inner wall of the housing 110 on the side facing the drive body 127.

[0075] In some embodiments, both the atomizing assembly 200 and the liquid reservoir 300 are disposed in the first receiving cavity 1271, and the liquid reservoir 300 is arranged around the side of the atomizing assembly 200 facing the drive body 127. In some embodiments, the end of the atomizing tube 210 away from the nozzle assembly 550 can be inserted into the support plate portion 125, and the support plate portion 125 can provide support and limit the atomizing tube 210 to ensure the installation stability of the atomizing assembly 200. In addition, the support plate portion 125 and the atomizing tube 210 can rotate relative to each other, or the atomizing tube 210 and the nozzle assembly 550 can rotate relative to each other. The atomizing core 220 can be spaced apart from the support plate portion 125 and the nozzle assembly 550 along the axial direction of the atomizing assembly 200, so as to be able to communicate with the liquid passages of each liquid reservoir 330 in the liquid reservoir 300.

[0076] In some embodiments, the guide groove 122 may be formed in the portion of the drive member body 127 opposite to the first receiving cavity 1271, and the guide groove 122 may be configured as a spiral groove extending axially along the atomizing assembly 200. That is, the guide groove 122 may be arranged around the rotational axis of the drive member 120 and extend axially in the atomizing assembly 200. The housing 311 of the liquid storage cup 300 may have a guide protrusion 3112 protruding from the side facing the drive member body 127, and the guide protrusion 3112 may be a cylindrical structure extending radially along the liquid storage cup 300. The guide protrusion 3112 is slidably inserted into the guide groove 122. When the drive member 120 rotates relative to the housing 110, the guide protrusion 3112 may move axially along the atomizing device under the squeezing action of the inner wall of the guide groove 122, thereby allowing the liquid storage cup 300 to slide relative to the atomizing assembly 200. Thus, different liquid storage chambers 330 can be connected to the liquid inlet holes 211 on the atomizing tube 210, so that different liquid storage chambers 330 and atomizing core 220 form a liquid path connection, so as to supply atomizing matrix to atomizing core 220.

[0077] In some embodiments, the drive member 120 may be a sliding key slidably mounted on the side of the housing 110 opposite to the liquid reservoir 300, and the sliding direction of the drive member 120 may be parallel to the axial direction of the atomizing assembly 200. During use, the drive member 120 can be pushed to move along the axial direction of the atomizing assembly 200, thereby causing the liquid reservoir 300 to slide along the axial direction of the atomizing assembly 200, so as to realize the switching between different liquid reservoirs 330.

[0078] In some embodiments, the end of the drive body 127 away from the nozzle 400 may be provided with a first stepped surface 123 opposite to the end face of the housing 110 away from the nozzle 400. The mounting surface 114 of the housing 110 away from the nozzle 400 can slide against the first stepped surface 123. In some embodiments, a plurality of first positioning portions 111 are provided on the side of the mounting surface 114 facing the first stepped surface 123. The plurality of first positioning portions 111 may be spaced apart around the rotation axis of the drive member 120 and correspond one-to-one with a plurality of liquid storage chambers 330, i.e., the plurality of first positioning portions 111 are sequentially arranged along the movement path of the drive member 120. A second positioning portion 124 adapted to the first positioning portion 111 may be provided on the side of the first stepped surface 123 facing the mounting surface 114. One of the second positioning portions 124 may be selectively positioned and connected to the plurality of first positioning portions 111. For example, when the second positioning part 124 is positioned and connected to the first positioning part 111 corresponding to a liquid storage cavity 330, the liquid storage cup 300 can be moved to a position where the liquid storage cavity 330 and the atomizing component 200 form a liquid path connection.

[0079] In some embodiments, the first positioning part 111 may be a positioning groove formed on the mounting surface 114. The second positioning part 124 may be a positioning protrusion protruding from the first stepped surface 123 and adapted to the shape of the positioning groove.

[0080] In some embodiments, the first positioning part 111 may also be disposed on the inner wall of the housing 110 facing the drive member 120, and the second positioning part 124 may be disposed on the surface of the drive member body 127 facing the inner wall of the housing 110.

[0081] In some embodiments, a plurality of first marking portions 112 may be configured on the side of the outer casing 110 opposite to the liquid reservoir 300, and the plurality of first marking portions 112 are configured one-to-one with a plurality of first positioning portions 111 along the rotation direction of the drive member 120. In some embodiments, the plurality of first marking portions 112 may be numbered differently to correspond to different liquid reservoirs 330. A second marking portion 126 may be configured on the peripheral surface of the drive member body 127 relative to the exposed portion of the outer casing 110, and the second marking portion 126 may be configured corresponding to a second positioning portion 124 along the rotation direction of the drive member 120, that is, the second marking portion 126 may be in the same position as the second positioning portion 124 along the rotation direction of the drive member 120. In use, the user can identify the flavor of the atomized matrix in the liquid reservoir 330 currently connected to the atomizing component 200 through the first marking portion 112 and the second marking portion 126.

[0082] In some embodiments, the first positioning portion 111 may be disposed on the side of the first stepped surface 123 facing the mounting surface 114. The second positioning portion 124 may be disposed on the side of the mounting surface 114 facing the first stepped surface 123. Correspondingly, the first marking portion 112 may also be disposed on the portion of the drive body 127 exposed relative to the housing 110, and the second marking portion 126 may be disposed on the side of the housing 110 away from the liquid reservoir 300.

[0083] like Figure 2 and Figure 3 As shown, the atomizing device also includes an electrical component 530, which may include a power supply battery 531 and a circuit board 532 electrically connected. Both the power supply battery 531 and the circuit board 532 can be disposed in the second receiving cavity 1272. In some embodiments, the power supply battery 531 may be located on the side of the circuit board 532 facing the liquid storage cup 300. In some embodiments, a second through hole 1251 opposite to the atomizing tube 210 may be formed on the support plate portion 125, and the pins of the atomizing core 220 may pass through the second through hole 1251 and extend to the second receiving cavity 1272 to be electrically connected to the circuit board 532.

[0084] In some embodiments, the power supply battery 531 or circuit board 532 may be disposed in the space between the drive body 127 and the housing 110 or in the first accommodating cavity 1271.

[0085] In some embodiments, the atomizing device further includes a base plate 540, which can cover the opening of the drive body 127 away from the nozzle 400, and can be connected to the drive body 127 by means of snap-fit ​​connection, bonding or interference fit.

[0086] In some embodiments, the atomizing device further includes a fourth seal 512. The fourth seal 512 may be disposed between the base plate 540 and the circuit board 532. The periphery of the fourth seal 512 may seal against the surface of the drive body 127 facing away from the housing 110, thereby achieving a seal on the end of the drive body 127 facing away from the nozzle 400 and reducing the probability of leakage.

[0087] In some embodiments, an air inlet 541 may be provided on the base plate 540. A third through hole 5121 opposite to and communicating with the air inlet 541 may be provided on the fourth seal 512. A fourth through hole 5321 opposite to and communicating with the third through hole 5121 may be provided on the circuit board 532. Accordingly, the second accommodating cavity 1272 may be connected to the external environment in sequence through the fourth through hole 5321, the third through hole 5121 and the air inlet 541, and the other end of the second accommodating cavity 1272 may be connected to the atomizing assembly 200 through the second through hole 1251, thereby enabling the atomizing assembly 200 to be connected to the external environment.

[0088] In some embodiments, the atomizing device further includes a second liquid-absorbing member 522, which may be disposed on the side of the circuit board 532 facing the power supply battery 531 and arranged side by side with the power supply battery 531. The second liquid-absorbing member 522 can be used to absorb condensate and leakage that enters the space where the power supply battery 531 is located, thereby reducing the probability of further leakage of the atomizing matrix to the outside of the atomizing device. In some embodiments, the second liquid-absorbing member 522 may be a structure such as absorbent cotton.
