For example, an assembly or apparatus including one or more components is not limited to the one or more components listed but may optionally include one or more components not listed that are inherent to the described product or that the described functions should possess.

Referring to FIGS. 1 and 2, the disclosure provides an atomization device 100 capable of effectively preventing e-liquid leakage during storage and transportation. The atomization device 100 includes an e-liquid chamber assembly 10 and an atomization core assembly 30.

The atomization device 100 provided in the disclosure can be applied to electronic atomizers and the like.

Referring to FIGS. 3 and 4, the e-liquid chamber assembly 10 includes an e-liquid chamber outer-housing 11, an e-liquid chamber inner-housing 12, a first sealing structure 13, and a second sealing structure 14.

Optionally, the e-liquid chamber outer-housing 11 is hollow. Optionally, the e-liquid chamber outer-housing 11 is substantially tubular.

The disclosure does not specifically limit the shape of the e-liquid chamber outer-housing 11. Optionally, the e-liquid chamber outer-housing 11 is substantially cylindrical. Further optionally, one end of the e-liquid chamber outer-housing 11 has an opening, while another end of the e-liquid chamber outer-housing 11 is an annular closed end. The annular closed end of the e-liquid chamber outer-housing 11 has a through-hole that is in communication with an inner cavity of the e-liquid chamber outer-housing 11.

The disclosure does not specifically limit a material of the e-liquid chamber outer-housing 11. For example, the material of the e-liquid chamber outer-housing 11 may be, but is not limited to, metal, plastic, ceramic, etc. Optionally, the e-liquid chamber outer-housing 11 is a transparent tube to facilitate observation of an e-liquid level inside the e-liquid chamber outer-housing 11.

Optionally, the e-liquid chamber inner-housing 12 is hollow.

The disclosure does not specifically limit the shape of the e-liquid chamber inner-housing 12. Optionally, the e-liquid chamber inner-housing 12 is cylindrical. Further optionally, each of both ends of the e-liquid chamber outer-housing 11 has an opening.

The e-liquid chamber inner-housing 12 is disposed within the e-liquid chamber outer-housing 11. In other words, an outer diameter of the e-liquid chamber inner-housing 12 is smaller than an inner diameter of the e-liquid chamber outer-housing 11. In one embodiment, a central axis of the e-liquid chamber inner-housing 12 coincides with a central axis of the e-liquid chamber outer-housing 11. In another embodiment, the central axis of the e-liquid chamber inner-housing 12 may be offset from the central axis of the e-liquid chamber outer-housing 11.

The disclosure does not specifically limit the material of the e-liquid chamber inner-housing 12. For example, the material of the e-liquid chamber inner-housing 12 may be, but is not limited to, metal, plastic, ceramic, etc. Optionally, the e-liquid chamber inner-housing 12 is a steel tube, providing improved strength and good heat resistance.

The first sealing structure 13 forms a seal between a first end of the e-liquid chamber outer-housing 11 and a first end of the e-liquid chamber inner-housing 12.

Optionally, referring to FIGS. 3 and 4, the annular closed end of the e-liquid chamber outer-housing 11 includes an inner end surface 111 and an outer end surface 112 opposite the inner end surface 111, where the inner end surface 111 faces an inner side of the e-liquid chamber outer-housing 11. Further, a fixing tube 15 is provided on the inner end surface 111 of the first end of the e-liquid chamber outer-housing 11. The fixing tube 15 extends towards the inner cavity of the e-liquid chamber outer-housing 11. The fixing tube 15 may be integrally formed with the annular closed end. The fixing tube 15 is hollow. An outer diameter of the fixing tube 15 is smaller than an inner diameter of the e-liquid chamber inner-housing 12. Accordingly, at least part of the fixing tube 15 is disposed within an inner cavity of the e-liquid chamber inner-housing 12.

Further, referring to FIGS. 3 and 4, a nozzle 16 is provided on and protrudes from the outer end surface 112 of the e-liquid chamber outer-housing 11. The nozzle 16 is hollow. An inner cavity of the nozzle 16 is in communication with an inner cavity of the fixing tube 15. Furthermore, an inner diameter of the nozzle 16 is larger than an inner diameter of the fixing tube 15. The nozzle 16, the fixing tube 15, and a main body of the e-liquid chamber outer-housing 11 may be integrally formed.

Optionally, at least part of the first sealing structure 13 is disposed between an outer peripheral wall of the fixing tube 15 and an inner peripheral wall of the e-liquid chamber inner-housing 12. In other words, the first sealing structure 13 is sleeved on the outer peripheral wall of the fixing tube 15, and the first end of the e-liquid chamber inner-housing 12 is sleeved on an outer peripheral wall of the first sealing structure 13.

The disclosure does not specifically limit axial dimensions of the first sealing structure 13 and the fixing tube 15. In this embodiment, the axial dimension of the first sealing structure 13 is greater than the axial dimension of the fixing tube 15. In other embodiments, the axial dimension of the first sealing structure 13 may be smaller than the axial dimension of the fixing tube 15.

The disclosure does not specifically limit the structure of the first sealing structure 13. Optionally, the first sealing structure 13 is a sealing ring. For example, the first sealing structure 13 includes, but is not limited to, a rubber ring or a silicone ring. The first sealing structure 13 is sleeved on an outer periphery of the fixing tube 15, and an inner peripheral wall of the first sealing structure 13 tightly wraps the outer peripheral wall of the fixing tube 15.

The second sealing structure 14 forms a seal between a second end of the e-liquid chamber outer-housing 11 and a second end of the e-liquid chamber inner-housing 12.

Optionally, the second sealing structure 14 is disposed between an outer peripheral wall of the second end of the e-liquid chamber inner-housing 12 and an inner peripheral wall of the second end of the e-liquid chamber outer-housing 11.

The disclosure does not specifically limit the structure of the second sealing structure 14. Optionally, the second sealing structure 14 is a sealing ring. For example, the second sealing structure 14 includes, but is not limited to, a rubber ring or a silicone ring. The second sealing structure 14 is sleeved on the outer peripheral wall of the second end of the e-liquid chamber inner-housing 12. The inner peripheral wall of the second sealing structure 14 tightly wraps the outer peripheral wall of the second end of the e-liquid chamber inner-housing 12. The outer peripheral wall of the second sealing structure 14 is in close contact with an inner peripheral wall of the e-liquid chamber outer-housing 11.

Referring to FIGS. 3 and 4, the e-liquid chamber outer-housing 11, the e-liquid chamber inner-housing 12, the first sealing structure 13, and the second sealing structure 14 cooperatively define an e-liquid storage chamber 17.

Referring to FIGS. 3 and 4, the second end of the e-liquid chamber outer-housing 11 defines at least one first e-liquid hole 113. Optionally, the first e-liquid hole 113 is disposed on the outer peripheral wall of the e-liquid chamber outer-housing 11. Alternatively, the first e-liquid hole 113 may be a notch extending from an edge of an opening at the second end of the e-liquid chamber outer-housing 11 towards the first end. The disclosure does not specifically limit the shape of the first e-liquid hole 113. Optionally, the first e-liquid hole 113 may be circular, triangular, square, polygonal, or other shapes. The disclosure does not specifically limit the number (quantity) of first e-liquid holes 113. Optionally, there are multiple first e-liquid holes 113 evenly distributed along a periphery of the e-liquid chamber outer-housing 11. The number of first e-liquid holes 113 may be 2, 3, 4, 5, 6, or other numbers. In other embodiments, the number of first e-liquid holes 113 may be one.

At least part of the atomization core assembly 30 is disposed within the inner cavity of the e-liquid chamber inner-housing 12. Optionally, after assembly, the atomization core assembly 30 is disposed within the inner cavity of the e-liquid chamber inner-housing 12 and is closer to the second end of the e-liquid chamber inner-housing 12 than the first end of the e-liquid chamber inner-housing 12.

Referring to FIG. 4, the e-liquid chamber inner-housing 12 is in a first position when the e-liquid chamber assembly 10 is not assembled with the atomization core assembly 30. When the e-liquid chamber assembly 10 is not assembled with the atomization core assembly 30, the atomization core assembly 30 is in an unassembled state. In the unassembled state, the atomization core assembly 30 is outside the e-liquid chamber assembly 10. The atomization core assembly 30 is independent from the e-liquid chamber assembly 10. For the e-liquid chamber assembly 10, in the unassembled state, the e-liquid chamber inner-housing 12 is positioned in the first position relative to the e-liquid chamber outer-housing 11, the first end of the e-liquid chamber inner-housing 12 is spaced apart from (that is, not is contact with) the inner end surface 111 of the e-liquid chamber outer-housing 11, and an inner peripheral wall of the first end of the e-liquid chamber inner-housing 12 is sealed with the outer peripheral wall of the fixing tube 15 via the first sealing structure 13. An upper boundary of the first e-liquid hole 113 of the second end of the e-liquid chamber inner-housing 12 is farther away from the inner end surface 111 than an upper surface of the second sealing structure 14. Thus, both upper and lower ends of the e-liquid storage chamber 17 are in a sealed state, and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is not in communication with the e-liquid storage chamber 17. In this state, the e-liquid in the e-liquid storage chamber 17 is sealed, thereby making it less likely to experience issues such as leakage.

Referring to FIG. 5, the e-liquid chamber inner-housing 12 is in a second position when the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10. When the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10, the atomization core assembly 30 is in an assembled state. In the assembled state, the atomization core assembly 30 is mounted inside the e-liquid chamber inner-housing 12 of the e-liquid chamber assembly 10. For the e-liquid chamber assembly 10, in the assembled state, the e-liquid chamber inner-housing 12 is positioned in the second position relative to the e-liquid chamber outer-housing 11, the first end of the e-liquid chamber inner-housing 12 abuts against the inner end surface 111 of the e-liquid chamber outer-housing 11 (or, a distance between the first end of the e-liquid chamber inner-housing 12 and the inner end surface 111 of the e-liquid chamber outer-housing 11 is reduced compared to that in the unassembled state), and the inner peripheral wall of the first end of the e-liquid chamber inner-housing 12 is sealed with the outer peripheral wall of the fixing tube 15 via the first sealing structure 13.

A distance between the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 in the first position and the first end of the e-liquid chamber outer-housing 11 is greater than that a distance between the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 in the second position and the first end of the e-liquid chamber outer-housing 11. When the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 in the second position, the upper boundary of the first e-liquid hole 113 of the second end of the e-liquid chamber inner-housing 12 is closer to the inner end surface 111 than the upper surface of the second sealing structure 14, and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is in communication with the e-liquid storage chamber 17. In this state, the e-liquid in the e-liquid storage chamber 17 can flow through the first e-liquid hole 113 to the atomization core assembly 30 in the e-liquid chamber inner-housing 12, allowing the atomization core assembly 30 to heat and atomize the e-liquid, thereby achieving automatic e-liquid feeding before and during use.

During assembly of the atomization core assembly 30, the atomization core assembly 30 pushes the second end of the e-liquid chamber inner-housing 12 to move towards the first end, such that the e-liquid chamber inner-housing 12 can move from the first position to the second position, and thus the e-liquid storage chamber 17 switches from the sealed state to an automatic e-liquid feeding state.

The atomization device 100 provided in the disclosure includes the e-liquid chamber assembly 10 and the atomization core assembly 30. The e-liquid chamber assembly 10 includes the e-liquid chamber outer-housing 11, the e-liquid chamber inner-housing 12, the first sealing structure 13, and the second sealing structure 14. The e-liquid chamber inner-housing 12 is disposed within the e-liquid chamber outer-housing 11. The first sealing structure 13 forms a seal between the first end of the e-liquid chamber outer-housing 11 and the first end of the e-liquid chamber inner-housing 12. The second sealing structure 14 forms a seal between the second end of the e-liquid chamber outer-housing 11 and the second end of the e-liquid chamber inner-housing 12. The second end of the e-liquid chamber outer-housing 11 has the at least one first e-liquid hole 113. The e-liquid chamber outer-housing 11, the e-liquid chamber inner-housing 12, the first sealing structure 13, and the second sealing structure 14 collectively define the e-liquid storage chamber 17. At least part of the atomization core assembly 30 is disposed within the inner cavity of the e-liquid chamber inner-housing 12. When the e-liquid chamber assembly 10 is not assembled with the atomization core assembly 30, the e-liquid chamber inner-housing 12 is in the first position, and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is not in communication with the e-liquid storage chamber 17. When the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10, the e-liquid chamber inner-housing 12 is in the second position, and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is in communication with the e-liquid storage chamber 17. The distance between the first end of the e-liquid chamber outer-housing 11 and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 in the first position is greater than the distance between the first end of the e-liquid chamber outer-housing 11 and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 and in the second position. During storage and transportation, the atomization core assembly 30 is detached from the e-liquid chamber assembly 10. At this time, the e-liquid chamber inner-housing 12 in the e-liquid chamber assembly 10 is in the first position, and the e-liquid storage chamber 17 is in the sealed state to reduce the risk of e-liquid leakage. The first e-liquid hole 113 of the e-liquid chamber assembly 10 can switch between a closed state and an open state through detachment or assembly of the atomization core assembly 30, thereby achieving automatic e-liquid feeding.

When the e-liquid chamber assembly 10 is not assembled with the atomization core assembly 30 (i.e., in the unassembled state), a first predetermined gap is defined between the first end of the e-liquid chamber inner-housing 12 and the inner end surface 111 of the first end of the e-liquid chamber outer-housing 11.

Optionally, when the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10 (i.e., in the assembled state), a second predetermined gap is defined between the first end of the e-liquid chamber inner-housing 12 and the inner end surface 111 of the first end of the e-liquid chamber outer-housing 11. The second predetermined gap is less than the first predetermined gap. In other words, during assembly of the atomization core assembly 30, the distance between the first end of the e-liquid chamber inner-housing 12 and the inner end surface 111 of the first end of the e-liquid chamber outer-housing 11 decreases under pushing of the atomization core assembly 30.

Alternatively, when the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10 (i.e., in the assembled state), the first end of the e-liquid chamber inner-housing 12 abuts against the inner end surface 111 of the first end of the e-liquid chamber outer-housing 11. In this embodiment, the inner end surface 111 of the first end of the e-liquid chamber outer-housing 11 serves as a limiting structure during a process of the atomization core assembly 30 advancing into the e-liquid chamber assembly 10. Specifically, when the first end of the e-liquid chamber inner-housing 12 abuts against the inner end surface 111 of the e-liquid chamber outer-housing 11, the assembly of the atomization core assembly 30 is complete. Furthermore, the abutment of the first end of the e-liquid chamber inner-housing 12 with the inner end surface 111 of the e-liquid chamber outer-housing 11 can further enhance the sealing performance at the first end of the e-liquid storage chamber 17.

Optionally, referring to FIGS. 3 to 5, the e-liquid chamber assembly 10 further includes a support plate 18.

Referring to FIGS. 3 to 5, an inner peripheral wall of the second end of the e-liquid chamber outer-housing 11 is provided with a limiting boss 114. The limiting boss 114 is disposed towards an opening at the second end of the e-liquid chamber outer-housing 11.

The support plate 18 is disposed on the limiting boss 114.

The support plate 18 is hollow. The support plate 18 surrounds the outer peripheral side of the e-liquid chamber inner-housing 12. An inner peripheral wall of the support plate 18 is in contact with or close to an outer peripheral wall of the e-liquid chamber inner-housing 12. An outer peripheral wall of the support plate 18 is in contact with or close to the inner peripheral wall of the e-liquid chamber outer-housing 11.

The disclosure does not specifically limit the material of the support plate 18. For example, the material of the support plate 18 may be, but is not limited to, metal, plastic, ceramic, etc. Optionally, the support plate 18 is a steel plate to provide better support strength, and when the second sealing structure 14 is compressed, the steel plate can offer strong resistance to prevent deformation.

Furthermore, referring to FIGS. 3 to 5, the support plate 18, the e-liquid chamber inner-housing 12, and the e-liquid chamber outer-housing 11 cooperatively define the e-liquid storage chamber 17.

Referring to FIGS. 3 to 5, the second sealing structure 14 includes a first sealing ring 141.

The first sealing ring 141 is disposed at a side of the support plate 18 away from the e-liquid storage chamber 17.

The first sealing ring 141 surrounds the outer peripheral side of the e-liquid chamber inner-housing 12. The first sealing ring 141 is operable to form a seal between the outer peripheral side of the e-liquid chamber inner-housing 12 and an inner side wall of the e-liquid chamber outer-housing 11. An inner peripheral wall of the first sealing ring 141 tightly wraps the outer peripheral wall of the second end of the e-liquid chamber inner-housing 12. An outer peripheral wall of the first sealing ring 141 tightly fits with the inner peripheral wall of the e-liquid chamber outer-housing 11.

For ease of illustration, one end of each structure of the atomization device 100 closer to the nozzle 16 is referred to as a first end of that structure, while another end of each structure of the atomization device 100 farther away from the nozzle 16 is referred to as a second end of that structure.

Optionally, referring to FIGS. 3 to 5, the e-liquid chamber assembly 10 further includes an end cover 19. One end (i.e., the first end) of the end cover 19 abuts against a side of the first sealing ring 141 away from the support plate 18, and another end (i.e., the second end) of the end cover 19 fits with and covers the opening at the second end of the e-liquid chamber outer-housing 11.

Optionally, one end (i.e., the second end) of the first sealing ring 141 away from the support plate 18 defines a limiting groove. For example, the limiting groove may be an annular groove. In other embodiments, the limiting groove may also be a rectangular groove or an arc-shaped groove, etc. A limiting boss is provided on and protrudes from the first end of the end cover 19. A shape of the limiting boss matches a shape of the limiting groove (that is, the limiting boss and the limiting groove are complementary in shape). During a process of the end cover 19 covering and engaging with the first sealing ring 141, the limiting boss on the end cover 19 is positioned in the limiting groove on the first sealing ring 141.

In this embodiment, a hardness of the end cover 19 is greater than a hardness of the first sealing ring 141. The first sealing ring 141 may be a silicone ring. The end cover 19 is made of hard rubber. During a process of the end cover 19 covering and engaging with the first sealing ring 141, the first sealing ring 141 is compressed, forming a seal between the first end of the e-liquid chamber outer-housing 11 and the first end of the e-liquid chamber inner-housing 12.

The end cover 19 defines an end-cover hole 192 extending in an axial direction. The second end of the e-liquid chamber inner-housing 12 is disposed within the end-cover hole 192 to allow the atomization core assembly 30 to be positioned in the e-liquid chamber inner-housing 12 via the end-cover hole 192.

When the e-liquid chamber assembly 10 is not assembled with the atomization core assembly 30 (i.e., in the unassembled state), the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is disposed at one side of the support plate 18 away from the e-liquid storage chamber 17, that is, the upper boundary of the first e-liquid hole 113 (i.e., a boundary of the first e-liquid hole 113 closer to the first end) is farther away from the inner end surface 111 than the support plate 18 (with reference to the illustrated angle).

When the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10 (i.e., in the assembled state), at least part of the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is in communication with the e-liquid storage chamber 17. That is, the upper boundary of the first e-liquid hole 113 is closer to the inner end surface 111 than the support plate 18 (with reference to the illustrated angle).

Optionally, referring to FIGS. 3 to 5, the end cover 19 and the first sealing ring 141 define an e-liquid injection hole 191 extending through the end cover 19 and the first sealing ring 141. An axial direction of the e-liquid injection hole 191 is parallel to an axial direction of the end cover 19. The e-liquid injection hole 191 extends through both the end cover 19 and the first sealing ring 141. The e-liquid injection hole 191 is arranged offset from the end-cover hole 192 of the end cover 19. Furthermore, the e-liquid injection hole 191 also extends through the support plate 18. The e-liquid injection hole 191 is in communication with the e-liquid storage chamber 17, allowing the e-liquid to be refilled into the e-liquid storage chamber 17 via the e-liquid injection hole 191.

Referring to FIGS. 3 to 5, the e-liquid chamber assembly 10 further includes an e-liquid injection plug 20. The e-liquid injection plug 20 seals the e-liquid injection hole 191. When it is necessary to refill the e-liquid storage chamber 17 with the e-liquid, the e-liquid injection plug 20 is first pulled out, and then the e-liquid is filled into the e-liquid storage chamber 17 via the e-liquid injection hole 191. When it is not necessary to refill the e-liquid into the e-liquid storage chamber 17, the e-liquid injection plug 20 is used to seal the e-liquid injection hole 191, thereby sealing the e-liquid in the e-liquid storage chamber 17.

Optionally, referring to FIGS. 6 to 7, the atomization core assembly 30 includes an atomization cover 31. The atomization cover 31 fits with an inner side of the end-cover hole 192 of the end cover 19 and seals the end-cover hole 192 of the end cover 19. The atomization cover 31 has an abutting protrusion 311 that is operable to abut against the second end of the e-liquid chamber inner-housing 12. Specifically, the abutting protrusion 311 is annular and arranged on an outer peripheral wall of the atomization cover 31.

During mounting of the atomization core assembly 30 into the e-liquid chamber assembly 10, the abutting protrusion 311 pushes the e-liquid chamber inner-housing 12 to move from the first position to the second position, causing the first end of the e-liquid chamber inner-housing 12 to gradually approach the inner end surface 111 of the e-liquid chamber outer-housing 11.

In this embodiment, by designing the abutting protrusion 311 on the outer peripheral wall of the atomization cover 31, the abutting protrusion 311 can push the e-liquid chamber inner-housing 12 to move from the first position to the second position during mounting of the atomization core assembly 30 into the e-liquid chamber assembly 10. This movement causes the first end of the e-liquid chamber inner-housing 12 to gradually approach the inner end surface 111 of the e-liquid chamber outer-housing 11, thereby switching the e-liquid storage chamber 17 from the sealed state to the automatic e-liquid feeding state, facilitating automatic e-liquid feeding before and during use.

Optionally, referring to FIGS. 6 to 7, the atomization core assembly 30 further includes a heating wire assembly 32, an inner cotton layer 33, and an e-liquid storage cotton layer 34.

Part of the heating wire assembly 32 is fixed to the atomization cover 31, another part of the heating wire assembly 32 is disposed within the inner cotton layer 33. The e-liquid storage cotton layer 34 is sleeved around an outer side of the heating wire assembly 32 and an outer side of the inner cotton layer 33.

Optionally, the heating wire assembly 32 extends outward from a first end of the atomization cover 31. When the atomization core assembly 30 is in the assembled state, the heating wire assembly 32, the inner cotton layer 33, and the e-liquid storage cotton layer 34 are all located within the inner cavity of the e-liquid chamber inner-housing 12. The heating wire assembly 32 extends towards the nozzle 16. The inner cotton layer 33 is hollow. The inner cotton layer 33 wraps around part of the heating wire assembly 32 and is spaced apart from the atomization cover 31. Optionally, the inner cotton layer 33 is cylindrical.

The e-liquid storage cotton layer 34 is hollow. Optionally, the e-liquid storage cotton layer 34 is cylindrical. A second end of the e-liquid storage cotton layer 34 abuts against an end surface of the first end of the atomization cover 31. The abutting protrusion 311 is positioned farther away from the inner end surface 111 than the end surface of the first end of the atomization cover 31 (with reference to the illustrated angle).

Optionally, referring to FIGS. 6 to 7, a positioning tube 312 is further provided on and protrudes from the end surface of the first end of the atomization cover 31. The inner cotton layer 33 is disposed within the positioning tube 312. An inner peripheral wall of the e-liquid storage cotton layer 34 fits with an outer peripheral wall of the positioning tube 312. For example, the material of the positioning tube 312 may be metal.

When the atomization core assembly 30 is in the assembled state, a first end of the e-liquid storage cotton layer 34 may abut against or be close to a second end of the first sealing structure 13.

Optionally, referring to FIGS. 6 to 7, the atomization core assembly 30 further includes a ventilation tube 35. One end of the ventilation tube 35 surrounds one end of the atomization cover 31 and abuts against the abutting protrusion 311. Another end of the ventilation tube 35 is sleeved around an outer peripheral side of the first sealing structure 13. The e-liquid storage cotton layer 34 is compressed between the ventilation tube 35 and the positioning tube 312.

The disclosure does not specifically limit the material of the ventilation tube 35. For example, the material of the ventilation tube 35 may include, but is not limited to metal, plastic, ceramic, etc. Optionally, the ventilation tube 35 is a steel tube to provide better support strength. When the second sealing structure 14 is compressed, the steel tube can offer strong resistance to prevent deformation.

Referring to FIGS. 6 to 7, the ventilation tube 35 further includes a second e-liquid hole 351. An outer side of the second e-liquid hole 351 is operable to be in communication with the first e-liquid hole 113. The e-liquid storage cotton layer 34 is disposed at an inner side of the second e-liquid hole 351.

Optionally, the second e-liquid hole 351 is defined on an outer peripheral wall of the ventilation tube 35. Further optionally, the second e-liquid hole 351 is disposed near an edge of an opening of a second end of the ventilation tube 35. The disclosure does not specifically limit the shape of the second e-liquid hole 351. Optionally, the second e-liquid hole 351 may have a circular, triangular, square, or polygonal shape, among others. The disclosure also does not specifically limit the number (quantity) of second e-liquid holes 351. Optionally, there may be multiple second e-liquid holes 351, which can be evenly distributed along a periphery of the e-liquid chamber outer-housing 11. For example, the number of second e-liquid holes 351 may be 2, 3, 4, 5, or 6. In other embodiments, there may be only one second e-liquid hole 351.

When the first e-liquid hole 113 is in communication with the e-liquid storage chamber 17, the e-liquid in the e-liquid storage chamber 17 can flow through the first e-liquid hole 113 and the second e-liquid hole 351 into the e-liquid storage cotton layer 34, and the e-liquid can be evenly distributed in the e-liquid storage cotton layer 34, facilitating a uniform atomization of the e-liquid.

In the assembled state, the edge of the opening of the second end of the e-liquid chamber inner-housing 12 is positioned farther away from the inner end surface 111 than the support plate 18. The abutting protrusion 311 is also farther away from the inner end surface 111 than the support plate 18. A peripheral side wall of the abutting protrusion 311 is interference-fitted with the first sealing ring 141.

Optionally, referring to FIGS. 6 to 7, the atomization cover 31 further defines a cover hole 313. The cover hole 313, an inner cavity of the inner cotton layer 33, an inner cavity of the e-liquid storage cotton layer 34, an inner cavity of the first sealing structure 13, the inner cavity of the fixing tube 15, and the inner cavity of the nozzle 16 are sequentially connected, forming an airflow passage.

The atomization cover 31 is made of a conductive material.

Referring to FIGS. 6 to 7, the atomization core assembly 30 further includes an insulating member 36 and an electrode pin 37. The insulating member 36 is disposed within the cover hole 313 of the atomization cover 31. The electrode pin 37 extends through the insulating member 36. In other words, the insulating member 36 surrounds a peripheral side of the electrode pin 37, and the atomization cover 31 surrounds a peripheral side of the insulating member 36. The insulating member 36 is used to insulate the atomization cover 31 from the electrode pin 37.

Referring to FIGS. 6 to 7, the heating wire assembly 32 includes a first pin 321, a heating wire (covered by the inner cotton layer 33), and a second pin 322. The heating wire is connected between the first pin 321 and the second pin 322. One of the first pin 321 and the second pin 322 serves as a positive electrode, while the other serves as a negative electrode.

The atomization cover 31 is made of a conductive material. The atomization cover 31 is electrically connected to the first pin 321. The electrode pin 37 is electrically connected to the second pin 322.

Referring to FIGS. 6 to 7, an outer peripheral wall of the atomization cover 31 closer to a second end of the atomization cover 31 defines a mounting groove 314 for mounting of a sealing ring. The mounting groove 314 is annular. The atomization core assembly 30 further includes a second sealing ring 38. The second sealing ring 38 is disposed within the mounting groove 314 and forms a seal between the outer peripheral wall of the atomization cover 31 and an inner peripheral wall of the end cover 19.

Referring to FIG. 8, before operation, the e-liquid chamber assembly 10 and the atomization core assembly 30 are stored separately. At this time, the e-liquid storage chamber 17 within the e-liquid chamber assembly 10 is in the sealed state to reduce leakage.

Before refilling, the e-liquid chamber inner-housing 12 is assembled at the first position. Entire wall surfaces at both ends of the e-liquid chamber inner-housing 12 are in interference fit with the first sealing structure 13 and the second sealing structure 14, respectively, to form seals. At this time, a lower e-liquid outlet of the e-liquid chamber inner-housing 12 is disposed outside the e-liquid storage chamber 17. The e-liquid chamber outer-housing 11 are in interference fit with both the first sealing structure 13 and the second sealing structure 14 to form seals. These four sealing points prevent e-liquid leakage during the refilling process through the e-liquid injection hole 191, even if the e-liquid chamber assembly 10 is inverted. After refilling, the e-liquid injection plug 20 (e.g., a silicone plug) is mounted to the e-liquid injection hole 191 to form a seal, and at this point, the e-liquid is completely sealed, ensuring no leakage during storage and transportation of the e-liquid chamber assembly 10.

When the atomization device 100 is to be used, the atomization core assembly 30 is assembled with the e-liquid chamber assembly 10.

Referring to FIG. 8, in an initial state, the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is not in communication with the e-liquid storage chamber 17. During assembly of the atomization core assembly 30 into the e-liquid chamber assembly 10, the abutting protrusion 311 of the atomization cover 31 abuts against the e-liquid chamber inner-housing 12. As the atomization core assembly 30 is inserted, the atomization core assembly 30 pushes the e-liquid chamber inner-housing 12 towards the inner end surface 111, causing the first e-liquid hole 113 at one end of the e-liquid chamber inner-housing 12 to move towards the inner end surface 111 and gradually come into communication with the e-liquid storage chamber 17.

Referring to FIG. 9, during assembly, the e-liquid chamber inner-housing 12 is pushed until it comes into contact with the inner end surface 111 of the e-liquid chamber outer-housing 11. At this point, the e-liquid chamber inner-housing 12 and the atomization core assembly 30 can no longer be inserted further inward, thereby completing assembly of the atomization device 100.

Referring to FIG. 10, after assembly, the e-liquid chamber inner-housing 12 is no longer sealed with the second sealing structure 14. Instead, a seal is formed between the atomization cover 31 and the second sealing structure 14, and a seal is also formed between the ventilation tube 35 and the first sealing structure 13. Additionally, a deformation force from interference fitting of the first sealing ring 141 of the second sealing structure 14 secures the atomization core assembly 30 in place. The entire first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is in communication with the e-liquid storage chamber 17. A downward flow path for the e-liquid in the e-liquid storage chamber 17 is driven by gravity, causing the e-liquid to flow automatically through the first e-liquid hole 113 into the e-liquid storage cotton layer 34. Capillary pores within the e-liquid storage cotton layer 34 absorb the e-liquid via capillary action, allowing the e-liquid to spread throughout the e-liquid storage cotton layer 34. The e-liquid storage cotton layer 34 is in contact with the inner cotton layer 33, which also absorbs the e-liquid from the e-liquid storage cotton layer 34 via capillary action to provide e-liquid for atomization by the heating wire 32, thereby achieving automatic e-liquid feeding.

Referring to FIG. 11, the disclosure also provides an electronic atomizer 1000, which includes an atomization rod 200 and the atomization device 100 provided in any one of the above embodiments. A connection end of the atomization device 100 is provided with at least one first magnetic member 40. The first magnetic member 40 includes, but is not limited to, a magnet.

A connection end of the atomization rod 200 is provided with at least one second magnetic member 50. The second magnetic member 50 includes, but is not limited to, a magnet.

The atomization device 100 and the atomization rod 200 are magnetically connected to each other via the first magnetic member 40 and the second magnetic member 50. The atomization rod 200 further includes a battery 60 configured to power the atomization core assembly 30. Optionally, a negative terminal of the battery 60 is electrically connected to the atomization cover 31 and the first pin 321, and a positive terminal of the battery 60 is electrically connected to the electrode pin 37 and the second pin 322, thereby forming an atomization heating circuit for heating the atomization wire.

The electronic atomizer 1000 provided in the disclosure includes the atomization rod 200 and the atomization device 100. The atomization device 100 includes the e-liquid chamber assembly 10 and the atomization core assembly 30. The e-liquid chamber assembly 10 includes the e-liquid chamber outer-housing 11, the e-liquid chamber inner-housing 12, the first sealing structure 13, and the second sealing structure 14. The e-liquid chamber inner-housing 12 is disposed within the e-liquid chamber outer-housing 11. The first sealing structure 13 forms a seal between the first end of the e-liquid chamber outer-housing 11 and the first end of the e-liquid chamber inner-housing 12. The second sealing structure 14 forms a seal between the second end of the e-liquid chamber outer-housing 11 and the second end of the e-liquid chamber inner-housing 12. The second end of the e-liquid chamber outer-housing 11 has the at least one first e-liquid hole 113. The e-liquid chamber outer-housing 11, the e-liquid chamber inner-housing 12, the first sealing structure 13, and the second sealing structure 14 collectively define the e-liquid storage chamber 17. At least part of the atomization core assembly 30 is disposed within the inner cavity of the e-liquid chamber inner-housing 12. When the e-liquid chamber assembly 10 is not assembled with the atomization core assembly 30, the e-liquid chamber inner-housing 12 is in the first position, and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is not in communication with the e-liquid storage chamber 17. When the atomization core assembly 30 is mounted into the e-liquid chamber assembly 10, the e-liquid chamber inner-housing 12 is in the second position, and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 is in communication with the e-liquid storage chamber 17. The distance between the first end of the e-liquid chamber outer-housing 11 and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 in the first position is greater than the distance between the first end of the e-liquid chamber outer-housing 11 and the first e-liquid hole 113 of the e-liquid chamber inner-housing 12 and in the second position. The connection end of the atomization device 100 is provided with the at least one first magnetic member 40, and the connection end of the atomization rod 200 is provided with the at least one second magnetic member 50. The atomization device 100 and the atomization rod 200 are magnetically connected to each other via the first magnetic member 40 and the second magnetic member 50. The atomization rod 200 further includes the battery 60 configured to power the atomization core assembly 30. During storage and transportation, the atomization core assembly 30 is detached from the e-liquid chamber assembly 10, such that the e-liquid chamber inner-housing 12 of the e-liquid chamber assembly 10 is in the first position, and the e-liquid storage chamber 17 is in the sealed state to reduce e-liquid leakage.

The e-liquid chamber assembly 10 is prefilled with e-liquid. The battery 60 is configured to power the atomization core assembly 30, enabling the atomization core assembly 30 to heat and atomize the e-liquid in the e-liquid chamber assembly 10, thereby producing aerosol for a user to inhale.
