[0036] The embodiment of the present application provides an atomization device 1.

[0037] It can be understood that the atomization device 1 of the embodiment of the present application can be any type of atomization device 1. The atomization device 1 can be used in the technical fields of medical, cosmetic, health care, electronic atomization, etc. For example, the atomization device 1 can be a scalp drug delivery atomization device.

[0038] Please refer to Figures 1 to 5 , the atomization device 1 comprises a tube shell 10, an atomization assembly and a power supply assembly 12.

[0039] At least part of the atomization assembly and the power supply assembly 12 is arranged in the tube shell 10, and the atomization assembly is electrically connected with the power supply assembly 12 to atomize the aerosol generating substrate.

[0040] The tube shell 10 has recessed notches 10a at both ends in the axial direction.

[0041] Among them, the tube shell 10 is a one-piece structure, the notch 10a at one end of the tube shell 10 and the non-recessed area 10b at the other end of the tube shell 10 are oppositely arranged along the axial direction of the tube shell 10, and along the projection perpendicular to the axial direction of the tube shell 10, the projection of the notch 10a at one end of the tube shell 10 coincides with the projection of the non-recessed area 10b at the other end of the tube shell 10.

[0042] Here, the aerosol generating substrate includes, but is not limited to, a material for medical, health, health, beauty, etc. purposes. For example, it includes, but is not limited to, a drug, a material containing nicotine or a material not containing nicotine, etc. For example, it can be a solid or liquid material in which a plant such as tobacco is used as a main raw material and a corresponding aerosol forming agent and aroma material are added.

[0043] The power supply assembly 12 is configured to supply power to the atomization assembly to atomize the aerosol generating substrate to form an aerosol. It can be understood that the atomization assembly at least includes a structure for atomizing the aerosol generating substrate. In some embodiments, the atomization assembly can include a structure for storing liquid and a structure for atomizing the aerosol generating substrate.

[0044] The tube shell 10 can serve as an appearance component of the atomization device 1 to protect the atomization assembly and the power supply assembly 12, and reduce the influence of external dust, moisture and impact on the atomization assembly and the power supply assembly 12. At the same time, the tube shell 10 can also provide structural support for the entire atomization device 1, and increase the positioning and connection stability between the atomization assembly and the power supply assembly 12.

[0045] The atomization assembly and the power supply assembly 12 can have part of their structures accommodated in the tube shell 10, or all structures of at least one of them can be accommodated in the tube shell 10, which is not limited here.

[0046] The tube shell 10 has recessed notches 10a at both ends in the axial direction, i.e., the tube shell 10 is recessed inward at both ends in the axial direction to form a non-planar or lower space than the surrounding area. The part of the tube shell 10 other than the notches at both ends in the axial direction is the non-recessed area 10b.

[0047] Exemplarily, the tube shell 10 can have a cylindrical structure, and the notches 10a are formed by recessing the circumference of the end face of both ends of the tube shell 10 inward. The notches 10a and the non-recessed area 10b can have a smooth transition to form a smooth curve on the entire circumference. In this way, the two ends of the tube shell 10 have no obvious edges, corners, etc., reducing the probability of damage to the atomization assembly and the power supply assembly 12 by the corner parts, and increasing the installation reliability.

[0048] It can be understood that the provision of the notches 10a can also serve as a reference for the assembly of the atomization assembly and the power supply assembly 12, improving the assembly efficiency and accuracy.

[0049] Here, the number of notches 10a can be one, two, three or more, and the number of notches 10a corresponds one-to-one to the number of non-recessed areas. The notches 10a at both ends of the tube shell 10 are consistent in shape and size, and the non-recessed areas 10b at both ends of the tube shell 10 are consistent in shape and size.

[0050] The tube shell 10 is an integral component, that is, the tube shell 10 is integrally manufactured into a shape, and the tube shell 10 has no splicing marks, so that the outer surface of the atomizing device 1 is more neat and flat, the assembly process is reduced, and the appearance reliability is improved.

[0051] The notch 10a at one end of the tube shell 10 and the non-recessed area 10b at the other end of the tube shell 10 are arranged in axial opposition, that is, in the axial direction of the tube shell 10, the two ends in the axial direction are on one side of the notch 10a and on the other side of the non-recessed area 10b.

[0052] In a projection along a plane perpendicular to the axial direction of the tube shell 10, the projection of the notch 10a at one end of the tube shell 10 coincides with the projection of the non-recessed area 10b at the other end of the tube shell 10, that is, the size of the notch 10a at one end of the tube shell 10 is consistent with the size of the non-recessed area 10b at the other end of the tube shell 10, so that the tube shell 10 can be obtained by one cutting.

[0053] The one cutting described herein refers to that, when the tube shell 10 is manufactured, a long tube can be formed by stretching the same tube material, and then the long tube is cut.

[0054] Here, in the axial direction of the tube material, one cutting can obtain one end face of one tube shell 10 in the axial direction and the other end face of the other tube shell 10 in the axial direction. That is, two end faces of the tube shell 10 required can be obtained at one cutting, and the size of the notch 10a at one end of the tube shell 10 coincides with the size of the non-recessed area 10b at the other end of the tube shell 10, and the projections coincide.

[0055] Further, two cuttings can obtain the end face of the first tube shell 10, the end faces of the two ends of the second tube shell 10, and the end face of the other end of the third tube shell 10, to obtain one finished tube shell 10 and two semi-finished tube shells 10, and three cuttings can obtain two finished tube shells 10 and two semi-finished tube shells 10, and so on.

[0056] Here, the tube material can be precisely cut by laser cutting and numerical control machine tool cutting. The tube shell 10 can be made of a metal tube material that is stretched and cut.

[0057] It can be understood that the size of the tube shell 10 does not need to be large, and one stretched metal tube material can not only be made into multiple tube shells 10 by one cutting, but also can reduce the waste of the tube material.

[0058] In the related art, the pipe is first cut into multiple sections of flat pipe, and then the end face curve cutting process is performed on each flat pipe, which has low production efficiency. That is, two cutting processes are required, and the notches at both ends of the pipe shell coincide, the non-recessed areas coincide, the size of the pipe shell corresponding to the notch in the axial direction is smaller than the size of the non-recessed area, and the overall structural stability is poor.

[0059] The gap 10a at one end of the pipe shell 10 in the axial direction corresponds to the non-recessed area 10b at the other end and is projected to coincide, that is, the end faces of the pipe shell 10 at different ends in the axial direction can be obtained at the same time by one cutting process, the processing procedure is less, the production efficiency can be improved, and the defective rate is low. Moreover, the size of each part of the pipe shell 10 in the axial direction can be made consistent, so that the stress can also be relatively uniform, thereby increasing the overall structural stability and reducing material waste. Furthermore, the notches 10a at both ends are not arranged at opposite positions, which can facilitate reference from different directions during assembly, improve the assembly effect and accuracy, and of course, the arrangement of the notches 10a and the non-recessed areas 10b can also increase the appearance aesthetics of the pipe shell 10 and improve the appearance performance of the atomizing device 1.

[0060] For example, in some embodiments, referring to Figure 5 , the pipe shell 10 has two notches 10a and two non-recessed areas 10b at both ends, and the notches 10a and the non-recessed areas 10b are arranged alternately in the circumferential direction at any one end. The adjacent two sides of any one notch 10a are non-recessed areas 10b, and the two sides of any one non-recessed area 10b are notches 10a.

[0061] In some embodiments, the size of the pipe shell 10 at any position in the axial direction is consistent. In this way, the stress of each part of the pipe shell 10 can be relatively uniform, thereby facilitating stable protection and support.

[0062] For example, in some embodiments, referring to Figure 3 and Figure 5 , the pipe shell 10 is mirror-symmetric about the center line of the pipe shell 10.

[0063] Here, the center line is the central axis of the pipe shell 10.

[0064] That is, the pipe shell 10 has a mirror-symmetric structure, and the positions and shapes of the notches 10a on both sides are exactly the same, and the positions and shapes of the non-recessed areas 10b on both sides are exactly the same.

[0065] In this embodiment, the pipe shell 10 is mirror-symmetric about the center line, and the multiple notches 10a at the same end can be symmetrically distributed, which further facilitates the notches 10a as reference points during assembly, and also increases the consistency of the product and the appearance aesthetics of the atomizing device 1.

[0066] In some embodiments, the notch 10a at either end of the tube shell 10 along the axial direction is rounded to transition to the non-recessed area 10b, and the radius R of the rounding is 5.5 mm to 15 mm. That is, 5.5 mm≤R≤15 mm, for example, 5.5 mm, 6 mm, 7.5 mm, 8.2 mm, 9.6 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc.

[0067] In this embodiment, the size of the rounding R is neither too large nor too small, which facilitates the smooth connection of the notch 10a to the non-recessed area 10b and increases the appearance reliability of the tube shell 10 while preventing scratching of the atomization assembly.

[0068] The matching mode of the power supply assembly 12 and the atomization assembly is not limited. For example, the power supply assembly 12 and the atomization assembly can be axially butted.

[0069] In some embodiments, referring to Figures 2 to 5 , the power supply assembly 12 includes a bracket 122 and a battery 123, and the battery 123 is accommodated in the bracket 122. For example, the tube shell 10 is sleeved on the outer periphery of the bracket 122 and the battery 123.

[0070] In this embodiment, the bracket 122 is provided with a foolproof structure, and the atomization assembly is provided with a matching structure. When the foolproof structure and the matching structure are matched with each other, the atomization assembly is accommodated in the tube shell 10, and the atomization assembly is electrically connected to the battery 123. When the foolproof structure and the matching structure are misaligned, at least part of the atomization assembly is located outside the tube shell 10 and separated from the battery 123.

[0071] Here, the matching of the foolproof structure and the matching structure can enable the atomization assembly to butt against the bracket 122 in a correct manner, thereby completing the electrical connection to the battery 123, improving the installation convenience, and effectively reducing the security risks caused by incorrect installation. When the foolproof structure and the matching structure are misaligned, at least part of the atomization assembly is located outside the tube shell 10 and separated from the battery 123, i.e., cannot be electrically connected to the battery 123, thereby reducing the probability of accidental start-up when not properly assembled and further increasing the safety of the atomization device 1 in use.

[0072] In this embodiment, the butt joint of the foolproof structure on the bracket 122 and the matching structure on the atomization assembly can realize the installation of the atomization assembly, so that the atomization assembly is not easy to fall out, and can provide a correct installation direction for the butt joint of the atomization assembly and the power supply assembly 12, thereby increasing the assembly efficiency.

[0073] It can be understood that in the related art, a fixing groove needs to be processed on the inner surface of the tube material to realize the butt joint with the atomization assembly and the power supply assembly, etc. The product has multiple processing procedures and is prone to damage to the tube material, thereby increasing the defective rate.

[0074] In the embodiment, the cooperation of the cooperation structure and the fool-proof structure eliminates the need for machining a fixing groove on the tube shell 10, further reduces the machining process of the tube shell 10, and increases the assembly reliability of the atomization device 1.

[0075] The specific structures of the cooperation structure and the fool-proof structure are not limited.

[0076] In some embodiments, referring to Figure 4 , the fool-proof structure includes a protruding column 1221 protruding from the top side of the bracket 122, and the cooperation structure includes a groove 11b formed on the outer surface of the atomization assembly, and the protruding column 1221 is inserted into the groove 11b.

[0077] In the embodiment, the cooperation of the protruding column 1221 and the groove 11b realizes the cooperation of the bracket 122 and the atomization assembly, the structure of the protruding column 1221 and the groove 11b is simple, and when providing correct assembly positioning for the bracket 122 and the atomization assembly, the probability of disassembly of the atomization assembly is reduced, and the assembly stability of the atomization device 1 is increased.

[0078] The specific structure of the atomization assembly is not limited.

[0079] In some embodiments, referring to Figure 3 and Figure 5 , the atomization assembly includes an atomization core assembly 111 and a first liquid storage member 15, the first liquid storage member 15 is used for storing an aerosol generating substrate, the atomization core assembly 111 is connected with the first liquid storage member 15 to atomize the aerosol generating substrate, and the atomization assembly is electrically connected with the power supply assembly 12 through the atomization core assembly 111.

[0080] The atomization core assembly 11 is used for obtaining electric energy from the power supply assembly 12 to atomize the aerosol generating substrate to generate an aerosol. Exemplarily, the groove 11b can be formed on the atomization core assembly 11.

[0081] The way in which the atomization core assembly 11 atomizes the aerosol generating substrate is not limited. For example, it can be heating atomization, ultrasonic atomization, etc. In the embodiment in which the atomization core assembly 11 atomizes the aerosol generating substrate in the heating atomization manner, the structure of the atomization core assembly 11 is also not limited. For example, the atomization core assembly 11 can include a heating needle, a heating net, or a heating sheet, etc.

[0082] The connection manner of the atomization core assembly 11 and the first liquid storage member 15 is not limited, which can be detachable connection or non-detachable connection, and is not limited herein. Exemplarily, the atomization core assembly 11 and the first liquid storage member 15 are detachably connected, and after the aerosol generating substrate in the first liquid storage member 15 is used up, the first liquid storage member 15 can be replaced by releasing the connection relationship between the atomization core assembly 11 and the first liquid storage member 15.

[0083] The atomization core assembly 11 and the first liquid storage member 15 can be in a split structure.

[0084] In some embodiments, referring to Figure 2 The atomization core assembly 11 includes an atomization core 111 and a second liquid storage member 112 for storing the aerosol generating substrate, and the atomization core 111 is arranged in the second liquid storage member 112. The second liquid storage member 112 is in communication with the first liquid storage member 15 and the atomization core 111.

[0085] That is, when the atomization core assembly 11 is not connected to the first liquid storage member 15, the atomization core assembly 11 can store the aerosol generating substrate through the second liquid storage member 112. When atomization is needed, the aerosol generating substrate stored in the second liquid storage member 112 can reduce the risk of dry burning of the atomization core. At the same time, in this process, the aerosol generating substrate in the first liquid storage member 15 flows to the second liquid storage member 112 and is atomized by the atomization core. The first liquid storage member 15 can replenish the aerosol generating substrate and improve the atomization balance.

[0086] The atomization core can be formed in a structure such as a heating wire or a heating net, which is not limited here.

[0087] In some embodiments, referring to Figures 1 to 3 The atomization device includes a suction nozzle 14, which is at least sleeved on the outer periphery of the notch 10a of one end of the tube shell 10 to cover the notch 10a.

[0088] Here, the aerosol formed by atomization can diffuse outward through the suction nozzle 14 for use by a user.

[0089] That is, the suction nozzle 14 is directly sleeved on the notch of one end of the tube shell 10 to cover the notch 10a, so as to also cover the part of the structure of the atomization assembly exposed through the notch 10a of one end of the tube shell 10 to protect the power supply assembly 12. In this embodiment, the end surface of the suction nozzle 14 has low requirements, and the end surface of the suction nozzle 14 can be a flat end surface, which facilitates the reduction of the manufacturing difficulty of the suction nozzle 14 and enhances the protection of the tube shell 10.

[0090] In other embodiments, the end surface of the suction nozzle 14 that is connected to the tube shell 10 is adapted to the shape of the end surface of one end of the tube shell 10.

[0091] That is, the end surface of the suction nozzle 14 that is connected to the tube shell 10 also has a notch and a non-recessed area. When connected to the tube shell 10, the notch 10a of the suction nozzle 14 is connected to the non-recessed area 10b of the tube shell 10, and the non-recessed area of the suction nozzle 14 is connected to the notch of the tube shell 10. In this way, the overall flatness of the atomization device 1 can be increased, the protruding part of the appearance of the atomization device 1 can be reduced, and the appearance of the atomization device 1 can be made more beautiful. At the same time, the axial size of the suction nozzle 14 can be reduced, and the production cost can be reduced.

[0092] In some embodiments, the mouthpiece 14 is formed as a part of the atomization assembly. That is, the mouthpiece 14 is a component of the atomization assembly, and the mouthpiece 14 is also connected to the tube shell 10 when the atomization assembly is connected to the power assembly 12 and the tube shell 10. In this way, the assembly process is simplified, the assembly efficiency is improved, and the manufacturing difficulty of the mouthpiece 14 is reduced.

[0093] Here, the mouthpiece 14 as a part of the atomization assembly means that the mouthpiece 14 cannot be detached from the atomization assembly.

[0094] In another embodiment, the mouthpiece 14 and the atomization assembly are in a split structure. That is, the mouthpiece 14 and the atomization assembly are manufactured separately, and the mouthpiece 14 is connected to the atomization assembly and the tube shell 10 after the atomization assembly is connected to the power assembly 12 and the tube shell 10. In this way, the mouthpiece 14 is adapted to the shape of the end face of the tube shell 10, and the appearance of the atomization device 1 is improved.

[0095] Here, the mouthpiece 14 and the atomization assembly in a split structure means that the mouthpiece 14 and the atomization assembly are two independent structures, and the mouthpiece 14 can be detached from the atomization assembly.

[0096] In some embodiments, referring to Figure 3 , the first liquid storage member 15 can have a through hole 15a, and the mouthpiece 14 can pass through the through hole 15a to communicate with the atomization cavity defined by the atomization core assembly 11, so as to guide the aerosol out of the atomization cavity. The mouthpiece 14 passing through the through hole 15a can further position the first liquid storage member 15, and reduce the probability of displacement of the first liquid storage member 15. In some embodiments, referring to Figures 1 to 3 , the atomization device 1 further comprises a bottom cover 13, and the bottom cover 13 at least covers the outer periphery of the notch 10a of the other end of the tube shell 10 to cover the notch 10a.

[0097] That is, the bottom cover 13 directly covers the notch 10a of the other end of the tube shell 10 to cover the notch 10a, so as to also facilitate covering the part of the power supply structure in the power assembly 12 exposed through the notch 10a of the other end of the tube shell 10, so as to protect the power assembly 12. In this embodiment, the end face of the bottom cover 13 is low in requirement, and the end face of the bottom cover 13 can be a flat end face, so as to facilitate reducing the manufacturing difficulty of the bottom cover 13 and enhancing the protection of the tube shell 10.

[0098] In another embodiment, the end face shape of the bottom cover 13 connected to the tube shell 10 is adapted to the end face shape of the other end of the tube shell 10.

[0099] That is to say, the end surface of the bottom cover 13 that is in abutment with the tube shell 10 also has a notch and a non-recessed area.

[0104] In some embodiments, the power supply assembly 12 includes a circuit board 124 connected to the outer side of the support 122 and electrically connected to the battery 123. The circuit board 124 has a charging interface 124a, and the bottom cover 13 has a clearance 13a in which the charging interface 124a is arranged.

[0105] Here, the bottom cover 13 can close and protect the other end of the tube shell 10, and reduce the probability of exposure and damage of the internal structure of the power supply assembly 12.

[0106] The circuit board 124 can serve as a control center to manage the power distribution and control logic of the entire atomization device 1. The circuit board 124 is arranged on the outer side of the support 122, which can facilitate heat dissipation and maintenance of the circuit board 124.

[0107] The charging interface 124a is arranged to facilitate power supply to the circuit board 124, and further to the battery 123, so as to enable the atomization device 1 to be used continuously. Here, the charging interface 124a is arranged in the avoiding opening 13a, and can be flush with the end surface of the avoiding opening 13a, or recessed from the end surface of the avoiding opening 13a, or protrude from the end surface of the avoiding opening 13a.

[0108] The bottom cover 13 and the tube shell 10 can be coupled in various ways.

[0109] In some embodiments, as shown in Figure 3 part of the circuit board 124 is exposed to the outer surface of the tube shell 10 through the gap 10a. The bottom cover 13 can be directly sleeved on the outer periphery of the other end of the tube shell 10 to cover the gap 10a, or can be adapted to the shape of the end surface of the other end of the tube shell 10 to fit the gap 10a, thereby closing the gap 10a and protecting the circuit board 124.
