Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0033] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0034] The present application discloses an atomizing device, which is used in an atomizer to atomize liquid into gas for inhalation by a user.

[0035] The atomizing device disclosed in the present application includes a shell, a base, an atomizing tube 5 and an oil storage member 71; the shell has a first opening and an air outlet 121; the base is installed at the first opening of the shell and is sealed with the shell, and the base has an air inlet; the atomizing tube 5 is located in the shell, and the atomizing tube 5 connects the air inlet and the air outlet 121, and the atomizing tube 5, the shell and the base form an oil cavity, and the oil cavity is located radially outside the atomizing tube 5, and the atomizing tube 5 is provided with an oil inlet; the oil storage member 71 is located in the oil cavity, and the oil storage member 71 is arranged around the atomizing tube 5, and the oil storage member 71 has an embedded part embedded in the base, and the embedded part blocks the oil inlet.

[0036] In the atomization device disclosed in the present application, since the atomization tube 5, the shell and the base form an oil cavity, the oil storage part 71 is located in the oil cavity, the oil storage part 71 is arranged around the atomization tube, and at least part of the oil storage part 71 is embedded in the base, and the embedded part of the oil storage part 71 blocks the oil inlet on the atomization tube 5, so that the oil storage part 71 and the oil inlet connect the oil cavity and the central channel in the atomization tube 5 to form an oil inlet path. Please refer to the dotted arrow in Figure 1. The oil can enter the atomization tube 5 along the oil inlet path. In this way, through the double obstruction of the base and the oil storage part 71, the amount of oil entering the atomization tube 5 through the oil inlet path can be effectively reduced, which can effectively reduce the possibility of oil leakage along the oil inlet path, thereby helping to improve the sealing performance of the atomization device and the entire atomizer.

[0037] In some embodiments, referring to Figures 1 to 5, the atomizer tube 5 has a first end 51 and a second end 52 arranged along its length. The first end 51 is sealed with the housing, and the oil inlet includes a notch 53. The notch 53 is provided at the second end 52 of the atomizer tube 5. The tube wall of the second end 52 is sealed with the base, and the notch 53 and the base enclose a first through hole.

[0038] The atomizing device further includes an oil guide member 6 , which is plug-fitted to the atomizing tube 5 . The oil guide member 6 has a protruding portion 62 located in the notch 53 , and the protruding portion 62 blocks the first through hole.

[0039] In this way, the tube walls at both ends of the atomizing tube 5 are sealed with the shell and the base respectively, and the first through hole of the atomizing tube 5 is blocked by the protruding portion 62 of the oil guide member 6 to achieve sealing. In this way, both ends of the atomizing tube 5 can achieve sealing inside and outside the atomizing tube 5, which can effectively reduce the amount of oil entering the atomizing tube 5 along the connection between the atomizing tube 5 and the base or the shell, that is, reduce the leakage of oil, which helps to improve the sealing performance of the atomizing device and the atomizer.

[0040] In other embodiments, also referring to Figures 1 to 5 , the oil inlet further includes a second through-hole 54 provided on the wall of the atomizing tube 5; the oil guide 6 includes an annular portion 61 connected to the protruding portion 62, the annular portion 61 being located within the atomizing tube 5 and configured to block the second through-hole 54. This helps increase the area of ​​the oil inlet on the atomizing tube 5, while ensuring sealing performance, and can prevent insufficient oil intake into the atomizing device, which could affect the normal operation of the atomizing device and the entire atomizer.

[0041] Specifically, please refer to Figures 1 to 3. In some embodiments, the shell includes a shell body 1 and a sealing ring 2. The shell body 1 has a large cylinder 11 and a small cylinder 12. The large cylinder 11 and the small cylinder 12 are both cylindrical structures. The small cylinder 12 is located inside the large cylinder 11 in its radial direction. The small cylinder 12 is coaxial with the large cylinder 11. One end of the large cylinder 11 has a first opening, and the other end is connected to the cylinder wall of the small cylinder 12. The small cylinder 12 has an inner end and an outer end. The inner end is located inside the large cylinder 11, and the outer end is located outside the large cylinder 11 to form a nozzle of the atomizing device. The opening at the outer end of the small cylinder 12 forms an air outlet 121; the hardness of the sealing ring 2 is less than that of the shell body 1, and the sealing ring 2 can be a rubber part. The sealing ring 2 extends in the length direction of the small cylinder 12. The sealing ring 2 is inserted into the small cylinder 12 and has an interference fit. 2 is sealed with the inner wall of the small cylinder 12 through its radially outer protrusion. One end of the sealing ring 2 has an outer flange 22 extending toward its radially outer side. The outer flange 22 is positioned and matched with the inner end surface of the small cylinder 12. The other end of the sealing ring 2 also has an inner flange 21 extending toward its radially inner side. The sealing ring 2 also has an interference fit with the atomizing tube 5. The sealing ring 2 is sleeved on the first end 51 of the atomizing tube 5. The end surface of the first end 51 of the atomizing tube 5 is positioned and matched with the inner flange 21 of the sealing ring 2 to limit the relative position of the sealing ring 2 and the atomizing tube 5 in the longitudinal direction of the atomizing tube 5. The radially inner side of the sealing ring 2 also has a protrusion that is sealed and matched with the outer wall of the atomizing tube 5. In this way, the housing body 1 and the atomizing tube 5 can be sealed through the sealing ring 2, that is, the entire housing and the first end 51 of the atomizing tube 5 are sealed.

[0042] Of course, in some other embodiments, the shell body 1 and the sealing ring 2 in the shell can also be integrally formed using two different materials, wherein the hardness of the shell body 1 is greater than the hardness of the sealing ring 2, and the sealing ring 2 can be made of rubber material, which can improve the sealing performance between the shell and the atomizer tube 5.

[0043] The structure of the sealing ring 2 in the present application is not limited to the structure described in Figures 1 to 3. For example, the sealing ring 2 can be sleeved on the inner end of the small cylinder 12 and positioned to cooperate with the small cylinder 12. A ring groove is provided on the sealing ring 2 to seal with the first end 51 of the atomizing tube 5.

[0044] In some embodiments, please refer to Figures 1, 2, 4 and 5. The base includes a base 3 and a sealing seat 4. The base 3 has a positioning groove 36 with the notch facing the direction of the atomizing tube 5. The sealing seat 4 is installed in the positioning groove 36. The hardness of the sealing seat 4 is less than that of the base 3. The sealing seat 4 can be a rubber part. A protrusion is provided on the outer peripheral surface of the sealing seat 4. The sealing seat 4 and the positioning groove 36 are interference fit through the protrusion, which can ensure the sealing performance between the sealing seat 4 and the base 3.

[0045] Of course, in other embodiments, the base 3 and the sealing seat 4 in the base can also be integrally formed by using two materials of different hardness through overmolding, where the hardness of the base 3 is greater than the hardness of the sealing seat 4, and the sealing seat 4 can be made of rubber material, which can improve the sealing performance between the base 3 and the sealing seat 4.

[0046] In some embodiments, the base 3 is sealed with the wall of the second end 52 of the atomizing tube 5 through the sealing seat 4 , and the base 3 is also sealed with the oil guide member 6 and the oil storage member 71 in the axial direction of the atomizing tube 5 through the sealing seat 4 .

[0047] Specifically, referring again to Figures 1, 2, 4, and 5, the sealing seat 4 has a sealing groove 41 that seals and engages with the tube wall of the second end 52. In the axial direction of the atomizer tube 5, the axial end of the sealing seat 4 encloses the notch 53 to form a first through-hole. The axial end of the sealing seat 4 also axially seals with the annular portion 61 of the oil guide member 6. The axial end of the sealing seat 4 has a first sealing surface 43 and a second sealing surface 44 facing the atomizer tube 5. The first sealing surface 43 is located within the atomizer tube 5 in the radial direction of the atomizer tube 5, and the second sealing surface 44 is located within the notch 53 in the radial direction of the atomizer tube 5. Both the first sealing surface 43 and the second sealing surface 44 seal with the oil guide member 6 in the axial direction of the atomizer tube 5.

[0048] More specifically, please refer to Figures 4 and 5. The mouth of the notch 53 at the second end 52 is set back to the first end 51. Two notches 53 can be set, and they are evenly spaced in the circumferential direction of the atomizer tube 5 to facilitate the processing of the notch 53. The number of sealing grooves 41 corresponds to the number of notches 53. The sealing groove 41 is provided on the sealing seat 4. The sealing groove 41 is an arc-shaped groove. The circumferential dimension of the sealing groove 41 is the same as the circumferential dimension of the tube wall between the two adjacent notches 53 at the second end 52 of the atomizer tube 5, so that the sealing groove 41 can be sealed and inserted with the tube wall of the second end 52 of the atomizer tube 5; after the atomizer tube 5 and the sealing seat 4 are sealed and inserted, the notch 53 of the atomizer tube 5 and the sealing seat 4 form a first through hole.

[0049] The oil guide member 6 is plugged into and fitted with the second end 52 of the atomizer tube 5. Please refer to Figures 1 to 5. The annular portion 61 of the oil guide member 6 is located in the atomizer tube 5, and the protruding portion 62 is located in the notch 53 of the atomizer tube 5. The atomizer tube 5 structure with multiple notches 53 is convenient for assembling the oil guide member 6 and the atomizer tube 5, and can avoid the oil guide member 6 from curling. The oil guide member 6 has two protruding portions 62 corresponding to the notch 53, and the two protruding portions 62 are arranged in the radial direction of the oil guide member 6. The protruding portion 62 is located in the notch 53 and the contour of the protruding portion 62 matches the contour of the side wall of the notch 53, which helps to make the protruding portion 62 and the notch 53 sealed.

[0050] The first sealing surface 43 and the second sealing surface 44 are both arranged on the outer end surface of the sealing seat 4 facing away from the positioning groove 36. The first sealing surface 43 is located on the inner side of the sealing groove 41 in the radial direction of the sealing seat 4, and the second sealing surface 44 is located between two adjacent sealing grooves 41 in the circumferential direction of the sealing seat 4; the annular portion 61 of the oil guide member 6 is sealed with the first sealing surface 43 in the axial direction of the atomizer tube 5, and the protruding portion 62 of the oil guide member 6 is sealed with the second sealing surface 44 in the axial direction of the atomizer tube 5. In this way, the oil guide member 6 is sealed with the sealing seat 4 in the axial direction of the atomizer tube 5, so that the protruding portion 62 blocks the first through hole and meets the sealing performance of the inside and outside of the atomizer tube 5 at the connection position with the base, thereby improving the sealing performance of the entire atomizer device.

[0051] Of course, in other embodiments, the first sealing surface 43 on the sealing seat 4 can be spaced apart from the annular portion 61 of the oil guide member 6, and only the protruding portion 62 is axially sealed with the second sealing surface 44, which can also meet the sealing requirements of the connection position between the atomizer tube 5 and the base.

[0052] Alternatively, in other embodiments, the sealing groove 41 on the sealing seat 4 can be eliminated. After the oil guide member 6 and the atomizer tube 5 are inserted into each other, the end face of the oil guide member 6 can be flush with the end face of the second end 52 of the atomizer tube 5. The end face of the oil guide member 6 and the end face of the second end 52 of the atomizer tube 5 are both axially sealed with the axially outer end face of the sealing seat 4. This can also improve the sealing performance of the connection between the atomizer tube 5 and the base.

[0053] In some embodiments, the sealing seat 4 further has a protrusion 46 located radially outside the atomizer tube 5. The protrusion 46 is arranged on the radial outer groove wall of the sealing groove 41. The protrusion 46 extends in the axial direction of the atomizer tube 5. The protrusion 46 is sealed with the protruding portion 62 of the oil guide member 6 in the radial direction of the atomizer tube 5.

[0054] Specifically, referring to Figures 1 to 5, the convex edge 46 of the sealing seat 4 has a third sealing surface 45 facing the atomizer tube 5 in the axial direction of the atomizer tube 5, and the distance between the third sealing surface 45 and the groove bottom surface of the sealing groove 41 is greater than the distance between the second sealing surface 44 and the groove bottom surface. In this way, the convex edge 46 protrudes from the second sealing surface 44, and the convex edge 46 also has a radial sealing surface facing the atomizer tube 5 in the radial direction of the atomizer tube 5. The convex edge 46 is sealed in the radial direction of the atomizer tube 5 through its radial sealing surface with the protruding portion 62 of the oil guide member 6 to improve the sealing performance at the position of the first through hole.

[0055] It should be noted that, referring to Figures 1 to 5, the radial minimum dimension of the oil guide member 6 at the protruding portion 62 is equal to the outer diameter of the atomizer tube 5, and the outer end surface of the protruding portion 62 in the radial direction of the oil guide member 6 is a plane, so that the protruding portion 62 as a whole has a portion protruding from the outer peripheral surface of the atomizer tube 5. Since the sealing seat 4 has a large deformation ability and the oil guide member 6 can be an oil-guiding cotton, the oil-guiding cotton can also be deformed after being squeezed. In this way, the sealing seat 4 and the oil guide member 6 can make the protruding portion 62 located radially on the inner side of the convex edge 46 of the sealing groove 41 after deformation, thereby realizing the sealing cooperation between the protruding portion 62 and the sealing seat 4 in the radial direction.

[0056] Of course, in some other embodiments, if the axial sealing cooperation between the oil guide member 6 and the sealing seat 4 can already meet the sealing performance requirements, the flange 46 may not be provided on the sealing seat 4, and the third sealing surface 45 and the second sealing surface 44 may be provided to be coplanar, which facilitates the processing and manufacturing of the sealing seat 4.

[0057] In some embodiments, the second sealing surface 44 is coplanar with the first sealing surface 43. (See Figures 4 and 5.) This allows the end surface of the annular portion 61 facing the base and the end surface of the protruding portion 62 facing the base to be coplanar, facilitating the manufacture of the sealing seat 4 and the entire oil guide member 6. Of course, the first sealing surface 43 and the second sealing surface 44 may not be coplanar, i.e., the end surface of the annular portion 61 facing the base and the end surface of the protruding portion 62 facing the base may not be coplanar, as long as the first sealing surface 43 and the annular portion 61 are axially sealed, and the second sealing surface 44 and the protruding portion 62 are axially sealed.

[0058] In some embodiments, please refer to Figures 1, 2 and 4. The oil storage member 71 is an annular oil storage cotton. The oil storage member 71 is extended in the length direction of the atomizing tube 5. The oil storage member 71 is sleeved outside the atomizing tube 5. The oil storage member 71 has an inner side wall for fitting with the outer tube wall of the atomizing tube 5. The inner side wall of the oil storage member 71 blocks the radial outer opening of the second through hole 54 and the first through hole, and the annular portion 61 of the oil guide member 6 blocks the radial inner opening of the second through hole 54. The protruding portion of the oil guide member 6 62 is located in the first through hole, so that after the oil storage member 71 and the oil guide member 6 expand and deform, the oil guide member 6 and the oil storage member 71 can contact each other at the second through hole 54 and the first through hole, which is conducive to the oil guide member 6 absorbing the oil in the oil storage member 71 and realizing the transmission of oil inside and outside the atomizing tube 5; and the structure of arranging the oil storage member 71 outside the atomizing tube 5 to block the second through hole 54 and the first through hole can also reduce the oil in the oil guide member 6, and avoid leakage of too much oil in the oil guide member 6 that is too late to be atomized.

[0059] When the oil storage part 71 is assembled, the axial ends of the oil storage part 71 are respectively sealed and positioned with the outer flange 22 of the sealing ring 2 and the third sealing surface 45 provided on the convex edge 46 of the sealing seat 4 in the axial direction of the atomizer tube. After the oil storage part 71 absorbs oil and expands, the oil storage part 71 is respectively sealed with the sealing ring 2 and the sealing seat 4, which also helps to improve the sealing performance of the connection position between the atomizer tube 5 and the base and the outer shell.

[0060] In some embodiments, the oil chamber is located radially outside the atomizing tube 5 , the base has a mounting groove 31 with a notch facing the oil chamber, and the oil storage member 71 is completely embedded in the mounting groove 31 to form an embedded portion.

[0061] Specifically, please refer to Figures 1 to 4. The large cylinder 11, the small cylinder 12, the sealing ring 2, the atomizing tube 5, the sealing seat 4 and the base 3 form an oil chamber, which is located radially outside the atomizing tube 5. The oil storage part 71 is located in the oil chamber and transmits the absorbed oil to the oil guide part 6 through the second through hole 54 and the first through hole; the base 3 has a mounting groove 31 with a notch facing the oil chamber, and a positioning groove 36 for installing the sealing seat 4 is arranged on the bottom wall of the mounting groove 31. The groove side wall of the mounting groove 31 has a radial inner side surface of a radial outer side surface, and the radial outer side surface is sealed with the inner cylinder wall of the large cylinder 11. The radial inner side surface is used to limit the expansion size of the embedded part in the radial direction to prevent the oil storage part 71 from absorbing too much oil, so as to reduce the residual oil rate of the atomizing device. The oil storage component 71 is entirely embedded in the mounting groove 31 of the base 3, and the oil storage component 71 as a whole forms an embedded part.
