The second extending wall 1116 is connected to the first extending wall 1115 and extends toward the partition wall 1114 in a direction perpendicular to the first extending wall 1115. The second extending wall 1116 may be generally annular and is coaxially arranged with the receiving portion 111a. The second extending wall 1116 and the first extending wall 1115 define a second cavity 1117.

[0065] like Figure 8 , Figure 9 and Figure 11As shown, in this embodiment, the atomizing structure 12 may include a porous body 121, a heating element 122, a fixing tube 123, and a conductive connector 124. The porous body 121 is generally a columnar structure with both ends open. Specifically, the porous body 121 is cylindrical and has a central through hole 1211. The central through hole 1211 can be coaxially arranged with the receiving portion 111a, and it can form a partial air outlet channel for the output of aerosol generated after atomization. In some embodiments, the porous body 121 can be a ceramic porous body. Of course, it is understood that in some other embodiments, the porous body 121 is not limited to a ceramic porous body, and it can be a cotton core. In some embodiments, the heating element 122 is disposed on the porous body 121. Specifically, the heating element 122 is disposed on the inner surface of the porous body 121, and it can be a heating mesh. Of course, it is understood that in some other embodiments, the heating element 122 is not limited to a heating mesh, and it can be a heating wire or a heating plate, etc. The heating element 122 can generate heat to heat the liquid matrix on the porous body 121 when energized.

Specifically, the second liquid storage structure 13 can be a ceramic porous body or a liquid storage cotton. The second liquid storage structure 13 can be columnar and have a through-end structure. It can be sleeved on the outer periphery of at least part of the atomizing structure 12 and coaxially arranged with the atomizing structure 12. Specifically, the second liquid storage structure 13 can be a hollow cylinder. In some embodiments, the second liquid storage structure 13 can be sleeved on the outer periphery of the fixing tube 123 of the atomizing structure 12 and correspondingly arranged with the porous body 121, and then sleeved on the outer periphery of the porous body 121 and coaxially arranged with the porous body 121. The second liquid storage structure 13 can be in liquid-conducting communication with the porous body 121 through the liquid inlet 1231. That is, the liquid matrix on the second liquid storage structure 13 can enter the porous body 121 through the liquid inlet 1231 to supply liquid to the porous body 121. In some embodiments, the axial length of the second liquid storage structure 13 may be greater than or equal to the axial length of the porous body 121. One end of the second liquid storage structure 13 may be placed on the support base 113, and the other end may extend to the partition wall 1114.

It can be used to seal against the mating portion 111b and the nozzle assembly 20, preventing leakage of the liquid matrix from the liquid supply channel 40 and enhancing the overall sealing performance. In some embodiments, the sealing member 14 can be a silicone component. Of course, it is understood that in other embodiments, the sealing member 14 is not limited to a silicone component, but can be a plastic component or other elastic structure.

The first liquid-absorbing structure 15 can have a through-hole structure at both ends and be coaxially arranged with the porous body 121. The porous body 121, the fixing tube 123, the first liquid-absorbing structure 15, and the nozzle assembly 20 are sequentially connected to form an air outlet channel. In some embodiments, the first liquid-absorbing structure 15 can be absorbent cotton, which can absorb the condensate formed by the condensation of the aerosol generated during atomization, preventing leakage from the atomizer 100. In other embodiments, the first liquid-absorbing structure 15 can be omitted.

[0069] In this embodiment, the atomizing component 10 further includes a conductive element 16, which can be electrically connected to the atomizing structure 12. There can be two conductive elements 16, which can be disposed on the atomizing base 11, specifically installed on the bottom wall of the second base 112 and extending inwards towards the second base 112.

When the conductive element 16 is electrically connected to the power supply component 200, the conductive connectors 124 are electrically connected to the power supply component 200, thereby enabling the power supply component 200 to supply power to the heating element 122. In some embodiments, the conductive element 16 can be a conductive post. Of course, it is understood that in other embodiments, the conductive element 16 is not limited to a conductive post; it can be a conductive sheet or other conductive structure.

In some embodiments, there can be two magnetic suction members 17, each of which can be columnar. Of course, it is understood that in some other embodiments, the magnetic suction member 17 is not limited to two, but can be one, and the magnetic suction member 17 is not limited to being columnar, but can be sheet-like. In some other embodiments, the magnetic suction member 17 can be omitted.

[0071] For example Figure 6 and Figure 7As shown, in this embodiment, the nozzle assembly 20 can be sleeved on the outer periphery of a portion of the atomizing seat 11 and the first liquid storage structure 30. Specifically, the nozzle assembly 20 includes a nozzle body 21 and a second liquid suction structure 22. The nozzle body 21 can be sleeved on the outer periphery of the mating part 111b and can be fixed to the mating part 111b by interference fit or screw connection, thereby making the nozzle assembly 20 and the atomizing assembly 10 form an integral structure, and the two can rotate relative to the first liquid storage structure 30 together. The nozzle body 21 can extend towards the receiving part 111a to be sleeved on the outer periphery of the first liquid storage structure 30, and can be fixed to the first liquid storage structure 30 by interference fit or screw connection. The nozzle body 21 is provided with an air outlet pipe 211, which is coaxially arranged with the atomizing structure 12 and communicates with the fixing pipe 123 for outputting aerosol. The nozzle assembly 20 has a suction port 2110, specifically, the suction port 2110 is formed at one end of the air outlet pipe 211. A second liquid-absorbing structure 22 can be disposed inside the nozzle body 21, located on top of the first liquid-absorbing structure 15. It can be in close contact with the inner wall of the nozzle body 21 and the first liquid-absorbing structure 15, and can be used to absorb condensate formed by aerosol condensation, further preventing leakage. The second liquid-absorbing structure 22 is a hollow structure with both ends open, communicating with the air outlet pipe 211 inside the nozzle body 21 and the first liquid-absorbing structure 15.

[0072] The first liquid absorption structure 15 and the second liquid absorption structure 22 can be selectively provided, that is, only the first liquid absorption structure or the second liquid absorption structure is provided.

[0073] like Figures 12 to 15 As shown, in this embodiment, the first liquid storage structure 30 can be sleeved on the outer periphery of at least a portion of the atomizing structure 12. Specifically, the first liquid storage structure 30 can be sleeved on the outer periphery of the receiving portion 111a and partially embedded in the nozzle assembly 20. In some embodiments, the first liquid storage structure 30 can be rotatably disposed relative to the atomizing base 11. Specifically, the overall structure formed by connecting the first liquid storage structure 30 with the atomizing assembly 10 and the nozzle assembly 20 can be rotatably disposed relative to each other. That is, the relative position of the first liquid storage structure 30 and the atomizing base 11 in the circumferential direction can be changed by rotating the first liquid storage structure 30 or the nozzle assembly 20.

[0074] In this embodiment, the first liquid storage structure 30 may include a liquid storage shell 31 and a capping assembly 32. The liquid storage shell 31 can be used to store a liquid matrix. The capping assembly 32 can cover the liquid storage shell 31 and can be assembled with the atomizing seat 11.

[0075] In this embodiment, the liquid storage shell 31 may include an outer ring wall 311, an inner ring wall 312, and an end wall 313. The outer ring wall 311 may be tubular, disposed on the outer periphery of the inner ring wall 312, and one end of which is connected to the end wall 313. The inner ring wall 312 may also be tubular, spaced apart from the outer ring wall 311, and the two may be coaxial. One end of the inner ring wall 312 is connected to the end wall 313. The first liquid storage structure 30 has a liquid storage cavity 314, specifically, the liquid storage cavity 314 is defined between the inner ring wall 312 and the outer ring wall 311. The liquid supply channel 40 is located between the liquid storage cavity 314 and the second liquid storage structure 13. The liquid storage shell 31 has an opening 315 at one end opposite to the end wall 313, and the opening 315 can communicate with the liquid storage cavity 314. The inner side of the inner ring wall 312 can define a channel 316, which can be used to allow the atomizing seat 11 to be partially inserted therein.

[0076] In this embodiment, the minimum distance from the second liquid storage structure 13 to the suction port 2110 is less than the minimum distance from the liquid storage cavity 314 to the suction port 2110. That is, the second liquid storage structure 13 is closer to the suction port 2110 than the liquid storage cavity 314. The liquid supply channel 40 can extend at least partially from the liquid storage cavity 314 to the suction port 2110 in the direction opposite to the suction direction, and communicate with the end of the second liquid storage structure 13 closest to the suction port 2110. This prevents the liquid matrix in the liquid storage cavity from continuously supplying liquid to the atomizing structure 12 under gravity during suction, avoiding oversaturation of the atomizing structure and preventing leakage. In other embodiments, the minimum distance from the second liquid storage structure 13 to the suction port 2110 may also be greater than or equal to the minimum distance from the liquid storage cavity 314 to the suction port 2110.

[0077] When the atomizer 100 is in the first placement state, the mouthpiece assembly 20 faces a first direction, which can be vertical and away from the placement plane. For example, the mouthpiece assembly 20 faces upward, and the liquid storage chamber 314 is below the liquid supply channel 40. The liquid matrix in the liquid storage chamber 314 cannot be supplied to the second liquid storage structure 13 through the liquid supply channel 40. When the atomizer 100 is in the second placement state, the mouthpiece assembly 20 faces a second direction (the atomizer 100 is inverted or tilted). This second direction can be vertical and towards the placement plane. For example, the mouthpiece assembly faces downward. Under the action of gravity, and when the liquid storage chamber 314 is connected to the liquid supply channel 40, the liquid matrix in the liquid storage chamber 314 can be transported to the second liquid storage structure 13 along the liquid supply channel 40.

[0078] In this embodiment, a limiting structure is provided on the atomizing seat 11 and the inner ring wall 312 to prevent the atomizing seat 11 from moving axially. Specifically, the limiting structure may include a limiting groove 1121 and a slider 317. The limiting groove 1121 is provided on the outer wall of the atomizing seat 11, specifically, it may be provided on the outer wall of the second seat 112, extending circumferentially along the second seat 112. The slider 317 is provided in the inner ring wall 312, protruding from the inner ring wall 312. When the atomizing seat 11 is assembled with the first liquid storage structure 30, the atomizing seat 11 can pass through the channel 316, and the slider 317 can slide into the limiting groove 1121 along the sliding groove 1122. When the atomizing seat 11 and the first liquid storage structure 30 rotate relative to each other, the slider 317 can be placed in the limiting groove 1121 and rotate, thereby providing axial limiting for the atomizing seat 11 and the first liquid storage structure 30. When the slider 317 is inserted into the slide groove 1122, the liquid supply channel 40 and the liquid storage chamber 314 are in a state of separation. When the slider 317 slides from the slide groove 1122 into the limiting groove 1121, it slides from the first set position of the limiting groove 1121 to the second set position. The liquid supply channel 40 can communicate with the liquid storage chamber 314. Due to the limitation of the limiting groove 1121, the atomizing seat 11 cannot be axially separated from the first liquid storage structure 30.

[0079] In this embodiment, the receiving portion 111a may partially pass through the channel 316. In some embodiments, the outer wall of the liquid storage shell 31 may also be provided with an anti-slip structure 318, which may include a plurality of protrusions spaced circumferentially along the liquid storage shell 31. By providing the anti-slip structure 318, the user can easily grip the liquid storage shell 31 and achieve an anti-slip effect. In some embodiments, the anti-slip structure 318 may be omitted.

[0080] In this embodiment, the cover assembly 32 can cover the opening 315. The cover assembly 32 may include an end cap 321, a rotating member 322, and a support member 323. The end cap 321 can be sleeved on the liquid storage shell 31 and cover the opening 315. The rotating member 322 is inserted into the liquid storage cavity 314 from the opening 315, located in the portion of the liquid storage cavity 314 near the opening 315, and can be connected to the atomizing seat 11. It can rotate relative to the liquid storage shell 31 in the liquid storage cavity 314. The support member 323 is fixedly disposed in the liquid storage cavity 314, located in the portion of the liquid storage cavity 314 near the opening 315, and located on the side of the rotating member 322 opposite to the opening 315. It can be fixedly connected to the liquid storage shell 31.

[0081] In this embodiment, the end cap 321 may include a covering portion 3211 and an extension portion 3213. The covering portion 3211 can cover the opening 315, and a limiting hole 3212 is provided on the covering portion 3211. The number of limiting holes 3212 is the same as the number of positioning posts 1119, which is two in this embodiment. The two limiting holes 3212 can be provided one-to-one with the two positioning posts 1119 of the atomizing seat 11. In some embodiments, the limiting hole 3212 can be an arc-shaped hole extending along the circumference of the covering portion 3211. The two ends of the limiting hole 3212 can correspond to the first position a and the second position b, respectively. The extension portion 3213 is disposed in the circumferential direction of the covering portion 3211 and extends in a direction perpendicular to the covering portion 3211. It can be located on the outer periphery of part of the liquid storage shell 31 and can be fixed to the liquid storage shell 31 by interference fit, snap-fit, or screw connection. Specifically, the end cap 321 and the liquid storage shell 31 can be fixed together by a snap-fit ​​structure. The snap-fit ​​structure may include a snap protrusion 3111 and a snap hole 3214. The snap protrusion 3111 may be provided on the outer side wall of the liquid storage shell 31. The snap hole 3214 is provided on the extension 3213 and corresponds one-to-one with the snap protrusion 3111. When the end cap 321 and the liquid storage shell 31 are assembled, the snap protrusion 3111 can be snapped into the snap hole 3214, thereby allowing the end cap 321 to be connected and fixed to the liquid storage shell 31.

[0082] In this embodiment, the rotating member 322 may be generally annular, and can be fitted around the outer periphery of the inner ring wall 312, and in close contact with the inner ring wall 312 and the outer ring wall 311, and in close contact with the cover portion 3211. The rotating member 322 may be a silicone component, which not only allows rotation but also provides a sealing function. In some embodiments, the end face of the rotating member 322 has a connecting through hole 3221, which allows the positioning post 1119 of the atomizing seat 11 to be inserted, thereby connecting the rotating member 322 to the atomizing assembly 10 and communicating with the liquid guiding hole 1118 in the positioning post 1119.

[0083] In this embodiment, the support member 323 can be sleeved on the outer periphery of the inner ring wall 312 and snapped and fixed to the outer ring wall 311. The support member 323 may include a support platform 3231. The support platform 3231 may be annular.

[0084] In this embodiment, the first liquid storage structure 30 has a liquid supply port 3232 at one end facing the suction port 2110. The liquid supply port 3232 is connected to the liquid storage cavity 314 and can supply liquid to the second liquid storage structure 13 through the liquid supply channel 40. This allows the liquid supply direction to be approximately opposite to the suction direction or to form a set angle greater than 0 degrees and less than 90 degrees. This prevents the liquid matrix in the liquid storage cavity from continuously supplying liquid to the atomizing structure under the action of gravity during suction, thereby preventing the atomizing structure 12 from becoming oversaturated, preventing leakage, improving the heating sufficiency of the liquid matrix on the atomizing structure 12, and enhancing the user experience.

[0085] Specifically, the liquid supply port 3232 can be disposed on the cover assembly 30, and there is at least one liquid supply port 3232. In this embodiment, there can be two liquid supply ports 3232, which can be disposed one-to-one with the two liquid guiding holes 1118. Further, the liquid supply port 3232 can be disposed on the support platform 3231 of the support member 323, and the liquid supply port 3232 can be a circular through hole. Of course, it is understood that in some other embodiments, the liquid supply port 3232 is not limited to a circular through hole.

[0086] The support member 323 also includes a locking portion 3233 that engages with the outer annular wall 311. This locking portion 3233 is located on the side of the support platform 3231 opposite to the rotating member 322. Multiple locking portions 3233 can be provided, spaced apart circumferentially along the support platform 3231. Each locking portion 3233 has a locking slot 3234. Multiple ribs 3112 are provided on the inner side of the outer annular wall 311 of the liquid storage shell 31. These ribs 3112 can be spaced apart circumferentially along the liquid storage shell 31, and each rib 3112 corresponds to a locking slot 3234. When the support member 323 is assembled with the liquid storage shell 31, the ribs 3112 can engage with the locking slots 3234, thereby fixing the support member 323 and the liquid storage shell 31 circumferentially. Meanwhile, the surface of the rib 3112 facing the support member 323 restricts the support member 323 from moving downward in the axial direction, while the cover portion 3211 restricts the support member 323 and the rotating member 322 from moving upward in the axial direction. In some embodiments, the method of fixing the support member 323 and the liquid storage shell 31 is not limited to snap-fit; the two can also be fixed by adhesive or by setting other connection structures.

[0087] Understandably, in other embodiments, the capping assembly 32 may also be without the end cap 321. In this case, the rotating member 322 can be press-fitted with the liquid storage shell 31, or a boss can be provided on the liquid storage shell 31 to restrict the rotating member 322 from dislodging from the liquid storage cavity 314. The support member 323 can also be restricted from dislodging from the liquid storage cavity 314 by press-fitting, or the support member 323 can be fixed to the liquid storage shell 31.

[0088] In this embodiment, the first liquid storage structure 30 can be at least partially installed in the power supply assembly 200 and can be fixedly disposed with the power supply assembly 200. In some embodiments, the power supply assembly 200 may include a housing 201, a bracket 202, a power source 203, and ejector pins 204. The housing 201 is a hollow structure with one end open and is longitudinally elongated. In some embodiments, the housing 201 may be generally cylindrical; it is understood that in other embodiments, the housing 201 is not limited to being cylindrical. The bracket 202 is disposed in the housing 201 for mounting the power source 203 and can also serve to support the atomizer 100. There are two ejector pins 204, which are spaced apart on the bracket 202 and are electrically connected to the power source 203. When the ejector pins 204 make one-to-one contact with the conductive parts 16 of the atomizer 100, the atomizer 100 and the power supply assembly 200 are electrically connected. When the ejector pin 204 is completely misaligned with the conductive part 16 of the atomizer 100, the atomizer 100 is disconnected from the power supply assembly 200.

[0089] In this embodiment, the first liquid storage structure 30 can be rotated relative to the atomizing base 11 by rotating the power supply component 200. Of course, it is understood that in other embodiments, the atomizing base 11 can also be rotated relative to the first liquid storage structure 30 and the power supply component 200 by rotating the nozzle assembly 20. Markings can be provided on the nozzle assembly 20 and the first liquid storage structure 30. These markings can be triangular structures. Of course, it is understood that in other embodiments, the position markings are not limited to triangular structures and can be arrows or other shapes. The markings can include a guide mark 212, a first position mark a, and a second position mark b. Specifically, the guide mark 212 can be disposed on the outer surface of the nozzle body 21 of the nozzle assembly 20, and the first position mark a and the second position mark b can be disposed on the outer surface of the liquid storage shell 31, corresponding to the first and second positions respectively.

[0090] Before use, the first liquid storage structure 30 needs to be installed to form the atomizer 100. Specifically, the first liquid storage structure 30 is fitted onto the atomizing seat 11, so that the slider 317 is located in the groove 1122, thereby being installed in place axially. At this time, the slider 317 enters the limiting groove 1121 from the groove 1122, and the atomizing seat 11 is in the second position relative to the first liquid storage structure 30. The first liquid storage structure 30 and the second liquid storage structure 13 are not connected. Moreover, the positioning post 1119 is inserted into the rotating member 322. Then, the atomizer 100 is installed onto the power supply assembly 200.

[0091] Rotating the power supply assembly 200 causes the first liquid storage structure 30 to rotate relative to the atomizing seat 11, so that the guide mark 212 points to the first position mark a, and the atomizing seat 11 is located at the first position relative to the first liquid storage structure 30. During the rotation, since the positioning post 1119 on the atomizing seat 11 is connected and fixed to the rotating component 322, the positioning post 1119 can move from the first end to the second end of the limiting hole 3212, so that the liquid guide hole 1118 is aligned with the liquid supply port 3232, which can drive the slider 317 to rotate from the first set position to the second set position in the limiting groove 1121. When the atomizing base 11 is in the first position relative to the first liquid storage structure 30, the connecting through hole 3221 is connected to the liquid supply port 3232, so that the liquid guiding hole 1118 is connected to the liquid supply port 3232. This allows the second liquid storage structure 13 to be connected to the liquid storage chamber 314 via the liquid supply channel 40. Furthermore, by inverting or tilting the atomizer 100 (with the nozzle assembly 20 facing downwards), the liquid matrix in the liquid storage chamber 314 can be supplied to the second liquid storage structure 13 via the liquid supply channel 40. At the same time, the conductive element 16 can be connected to the external circuit, that is, the conductive element 16 is in contact with the pin 204 of the power supply assembly 200. At this time, the atomizing structure 12 is in an energized state and can be used for suction.

[0092] When the atomizing base 11 is in use, the rotatable power supply component 200 rotates the first liquid storage structure 30 relative to the atomizing base 11, causing the guide mark 212 to point to the second position mark b. The atomizing base 11 is then positioned in the second position relative to the first liquid storage structure 30. During rotation, the positioning post 1119 can move from the second end of the limiting hole 3212 to the first end, thereby completely misaligning the connecting through hole 3221 with the liquid supply port 3232, and consequently completely misaligning the liquid guide hole 1118 with the liquid supply port 3232. Simultaneously, the slider rotates from the second set position to the first set position in the limiting groove 1121. When the atomizing base 11 is in the second position relative to the first liquid storage structure 30, the liquid guide hole 1118 and the liquid supply port 3232 are completely misaligned, meaning the liquid supply channel 40 is disconnected and not connected to the liquid storage chamber 314. This isolates the second liquid storage structure 13 from the liquid storage chamber 314, preventing the liquid storage chamber 314 from supplying liquid to the second liquid storage structure 13 and thus preventing leakage. Meanwhile, the conductive element 16 can be disconnected from the external circuit. Specifically, the conductive element 16 can be completely misaligned with the pin 204 of the power supply component 200. At this time, the slider 317 rotates within the limiting groove 1121 to the position where the slide groove 1122 is connected, and the first liquid storage structure 30 can be separated from the atomizing seat 11 to replace the new first liquid storage structure 30.

[0093] Figure 16 and Figure 17A second embodiment of the electronic atomizing device of this utility model is shown. The difference from the first embodiment is that, in the atomizing assembly 10, the heating element 122 of the atomizing structure 12 is not limited to being disposed inside the porous body 121, but can cover the outside of the porous body 121. The fixing tube 123 can be sleeved on a portion of the porous body 121, specifically on the section of the porous body 121 facing the mouthpiece assembly 20. The first liquid-absorbing structure 15 can be accommodated in the sealing member 14 and is coaxially arranged with the sealing member 14. The conductive member 16 can extend to the support base 113 and can be inserted into the support base 113, and is electrically connected to the conductive connector 124 of the atomizing structure 12 through the support base 113.

[0094] In some other embodiments, the rotating member 322 can be omitted, and the atomizing seat 11 and the first liquid storage structure 30 can be fixedly set to ensure that the liquid supply channel 40, the liquid storage chamber 314, and the second liquid storage structure 13 are always in communication.

[0095] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
