Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an aerosol generating device. Background Technology

[0002] An aerosol generator is an electronic device that atomizes a liquid into an aerosol for users to inhale. Existing aerosol generators mainly consist of an atomizing component and a battery component. The atomizing component atomizes the liquid into an aerosol, while the battery component provides power to the atomizing component. In related technologies, the atomizing component has a mounting cavity, and the battery component is installed within the mounting cavity, thus achieving assembly of the atomizing component and the battery component. However, during assembly, it is difficult to accurately determine the angle at which the battery component is inserted into the mounting cavity, and the battery component is prone to rotation relative to the atomizing component within the mounting cavity, thereby affecting the assembly stability between the battery component and the atomizing component.

[0008] Optionally, in one embodiment, the first limiting rib and the second limiting rib each have a front end and a rear end opposite to each other along their extension direction. The front end extends into the mounting cavity and is provided with a guide slope. The guide slope has a first side and a second side opposite to each other along its inclination direction. The first side is closer to the outer wall of the mounting cylinder than the second side, and the second side is closer to the rear end than the first side.

[0009] Optionally, in one embodiment, the inner wall surface of the mounting cavity is curved, and the first limiting rib and the second limiting rib are both provided with a clearance slope on the side away from the outer wall of the mounting cylinder; the clearance slope has a third side and a fourth side opposite to each other along its inclined direction, the third side being closer to the limiting groove than the fourth side, and the fourth side being closer to the outer wall of the mounting cylinder than the third side.

[0010] Optionally, in one embodiment, the mounting cavity has a plug-in opening for insertion of the second housing, and the limiting block has a bottom wall facing the plug-in opening and side walls connected to both sides of the bottom wall, with a guide arc surface connecting the bottom wall and the side walls.

[0011] Optionally, in one embodiment, the limiting block is integrally formed with the inner wall of the mounting cavity.

[0016] The aerosol generating device of this application has at least the following beneficial effects:

[0017] This aerosol application incorporates a first limiting structure on the first housing of the atomizing component and a second limiting structure on the second housing of the battery component. The first and second housings are plug-in assembled, and the first and second limiting structures are also plugged in and snapped together along the plugging / snap direction. During assembly, the assembler needs to align the first and second limiting structures to achieve the plugging / snap connection. With the first and second limiting structures as references, the assembler can better determine the insertion angle of the first and second housings. Furthermore, because the first and second limiting structures are plugged in and snapped together along the plugging / snap direction, relative rotation between the first and second housings is restricted, thus making relative rotation between the atomizing component and the battery component less likely and improving the assembly stability between them.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] To address the technical problem of unstable assembly of atomizing components and battery components in existing aerosol generators, such as... Figure 1 , Figure 3 and Figure 6 As shown, this application proposes an aerosol generator 100, which mainly includes an atomizing component 10 and a battery component 20, wherein... Figure 1 This is a schematic diagram of the structure of one embodiment of the aerosol generating device 100 of this application. Figure 3 for Figure 1 A schematic diagram of the atomizing component in the diagram. Figure 6 for Figure 1 A schematic diagram of the battery assembly.

[0031] like Figure 3 As shown, the atomizing component 10 is provided with a first housing 11, and a first limiting structure 12 is provided on the first housing 11, such as... Figure 6 As shown, the battery assembly 20 has a second housing 21, and the second housing 21 has a second limiting structure 22. Please refer to... Figure 1 and Figure 2One of the first housing 11 and the second housing 21 is plugged into the other, and one of the first limiting structure 12 and the second limiting structure 22 is plugged into the other along the plugging direction of the first housing 11 and the second housing 21.

[0032] Specifically, such as Figure 3 As shown, in one structural embodiment, the atomizing assembly 10 includes a first housing 11 and an atomizer 13 mounted on the first housing 11. The first housing 11 has an overall cylindrical shape and a mounting cavity 111 is formed inside the first housing 11. The atomizer 13 is a component used to atomize the atomizing liquid into an aerosol, and the atomizer 13 is at least partially located inside the mounting cavity 111 so that it can be electrically connected to the battery in the battery assembly 20 when the battery assembly 20 is inserted into the mounting cavity 111.

[0033] Corresponding to the atomizing component 10 in the above structural scheme, such as Figure 6 As shown, the battery assembly 20 mainly includes a second housing 21 and a battery (not shown) installed inside the second housing 21. Specifically, the second housing 21 includes at least a mounting cylinder 211, which is cylindrical in shape and has a battery cavity for mounting the battery. Figure 6 In the structural scheme shown, the second housing 21 also includes a base plate 214, the mounting cylinder 211 is fixed on the base plate 214, and the end of the mounting cylinder 211 away from the base plate 214 is provided with a cylinder opening 212, which is used for installing the battery into the mounting cylinder 211.

[0034] Please combine Figure 1 and Figure 2 When assembling the atomizing component 10 and the battery component 20 with the above structure, the mounting cylinder 211 of the second housing 21 is inserted into the mounting cavity 111 of the first housing 11 in a plug-in manner with the battery attached. The relative movement of the first housing 11 and the second housing 21 in the axial direction can be restricted by fasteners 213, threaded connectors, pins and other connectors.

[0035] Of course, in other embodiments, the first housing 11 can be plugged into the second housing 21. For example, the second housing 21 may have a receiving cavity for both housing the battery and housing the first housing 11. Alternatively, the second housing 21 may have two cavities, one for housing the battery and the other surrounding the battery-containing cavity and used for housing the first housing 11. In short, any plug-in installation of the first housing 11 and the second housing 21 is acceptable.

[0036] Crucially, in this embodiment, please refer to... Figure 2 , Figure 3 and Figure 6The first housing 11 is provided with a first limiting structure 12, and the second housing 21 is provided with a second limiting structure 22. When the first housing 11 and the second housing 21 are installed in a plug-in manner, the first limiting structure 12 and the second limiting structure 22 are also plugged in and snapped together along the plugging and unplugging direction of the first housing 11 and the second housing 21.

[0037] Specifically, the first housing 11 is provided with a mounting cavity 111, and the second housing 21 is inserted into the mounting cavity 111 of the first housing 11 in an axial direction along the mounting cavity 111. The first limiting structure 12 is disposed in the mounting cavity 111 of the first housing 11, and the second limiting structure 22 is disposed outside the second housing 21. Both the first limiting structure 12 and the second limiting structure 22 extend in the axial direction of the mounting cavity 111 to facilitate the insertion and snapping of the first limiting structure 12 and the second limiting structure 22.

[0038] Of course, if the first housing 11 is plugged into the second housing 21, the first limiting structure 12 can be located outside the first housing 11, and the second limiting structure 22 can be located inside the second housing 21.

[0039] It should be noted here that, regarding the specific construction of the first limiting structure 12 and the second limiting structure 22, optionally, one of the first limiting structure 12 and the second limiting structure 22 can be a limiting block 121 and the other a limiting groove 221. For example, in one embodiment, as... Figure 3 As shown, the first limiting structure 12 is a limiting block 121 and is disposed within the mounting cavity 111 of the first housing 11, as... Figure 6 As shown, the second limiting structure 22 is a limiting groove 221 and is disposed on the outer wall of the mounting cylinder 211.

[0040] Of course, in other embodiments, the first limiting structure 12 can also be a limiting groove, and the second limiting structure 22 can also be a limiting block. For example, it can be... Figure 2 , Figure 3 and Figure 6 For reference, a limiting groove can be provided in the mounting cavity 111 of the first housing 11, and the limiting groove extends along the axial direction of the mounting cavity 111. A limiting block can be provided on the outer wall of the mounting cylinder 211. When the second housing 21 is installed into the first housing 11, the limiting block outside the mounting cylinder 211 slides and engages with the limiting groove.

[0041] Additionally, it should be noted that when the limiting block 121 is placed inside the mounting cavity 111, the limiting block 121 can be fixed to the inner wall of the mounting cavity 111, or it can be spaced apart from and relatively fixed to the inner wall of the mounting cavity 111. Similarly, when the limiting block 121 is placed on the second housing 21, the limiting block 121 can be fixed to the outer wall of the mounting cylinder 211, or it can be spaced apart from and relatively fixed to the outer wall of the mounting cylinder 211.

[0042] In summary, the aerosol of this application, by setting a first limiting structure 12 on the first housing 11 of the atomizing component 10 and a second limiting structure 22 on the second housing 21 of the battery component 20, allows the first housing 11 and the second housing 21 to be assembled in a plug-in manner. The first limiting structure 12 and the second limiting structure 22 are also plugged in and snapped together along the plugging and snapping direction of the first housing 11 and the second housing 21. Thus, during assembly, the assembler needs to align the first limiting structure 12 and the limiting structure to achieve the plugging and snapping of the first limiting structure 12 and the second limiting structure 22. With the first limiting structure 12 and the second limiting structure 22 as a reference, the assembler can better find the insertion angle of the first housing 11 and the second housing 21. In addition, since the first limiting structure 12 and the second limiting structure 22 are plugged and snapped together along the insertion and removal direction of the first housing 11 and the second housing 21, the relative rotation of the first housing 11 and the second housing 21 can be restricted, thereby making it difficult for the atomizing component 10 and the battery component 20 to rotate relative to each other, thus improving the assembly stability between the atomizing component 10 and the battery component 20.

[0043] Optionally, in one embodiment, please combine Figure 1 , Figure 3 and Figure 6 The first housing 11 has a mounting cavity 111, and the second housing 21 includes a mounting cylinder 211 for mounting the battery. The mounting cylinder 211 is pluggably installed in the mounting cavity 111. A limiting block 121 is provided in the mounting cavity 111, and a limiting groove 221 is provided on the outer wall of the mounting cylinder 211. That is, in this embodiment, the atomizing component 10 and the battery component 20 are assembled by plugging the second housing 21 into the first housing 11. In this way, the inner cavity of the mounting cylinder 211 does not need to be made large enough to accommodate the first housing 11, thus facilitating battery fixation, or the second housing 21 does not need to have a separate cavity structure to accommodate the first housing 11, thus simplifying the structure of the second housing 21.

[0044] In this embodiment, the first limiting structure 12 is a limiting block 121 disposed within the mounting cavity 111 of the first housing 11, and the second limiting structure 22 is a limiting groove 221 disposed on the outer wall of the mounting cylinder 211. It should be noted that the limiting groove 221 can be formed in various ways. For example, optionally, in one embodiment, the outer wall portion of the mounting cylinder 211 is recessed inward to form the limiting groove 221.

[0045] Alternatively, in another embodiment, such as Figure 6As shown, a first limiting rib 23 and a second limiting rib 24 protrude from the outer wall of the mounting cylinder 211. The first limiting rib 23 and the second limiting rib 24 extend along the insertion and extraction direction of the second housing 21, and a limiting groove 221 is formed between the first limiting rib 23 and the second limiting rib 24 at intervals. That is, in this embodiment, by protruding the first limiting rib 23 and the second limiting rib 24 on the outer wall of the mounting cylinder 211 and forming a limiting groove 221 at intervals, not only can a plug-in snap-fit ​​connection with the limiting block 121 be achieved, but the first limiting rib 23 and the second limiting rib 24 can also serve as reinforcing ribs to strengthen the structural strength of the mounting cylinder 211, achieving two goals at once.

[0046] Optionally, in one embodiment, such as Figure 6 As shown, both the first limiting rib 23 and the second limiting rib 24 have a front end 25 and a rear end 26 opposite to each other along their extending direction. The front end 25 extends into the mounting cavity 111, and the front end 25 is provided with a guide slope 27. Figure 7 As shown, the guide slope 27 has a first side 271 and a second side 272 opposite to each other along its inclined direction. The first side 271 is closer to the outer wall of the mounting cylinder 211 than the second side 272, and the second side 272 is closer to the rear end 26 than the first side 271.

[0047] Specifically, in this embodiment, you can refer to Figure 3 The first housing 11 has a plug-in opening 112 for inserting the second housing 21. When the second housing 21 is inserted into the mounting cavity 111 of the first housing 11 through the plug-in opening 112, if the front ends 25 of the first limiting rib 23 and the second limiting rib 24 abut against the edge of the plug-in opening 112 due to inaccurate positioning by the assembler, the front ends 25 of the first limiting rib 23 and the second limiting rib 24 will gradually extend into the mounting cavity 111 under the guidance of the guide slope 27. This avoids the first limiting rib 23 and the second limiting rib 24 from getting stuck at the plug-in opening 112, making the assembly of the battery assembly 20 and the atomizing assembly 10 smoother and improving the assembly efficiency.

[0048] Optionally, in one embodiment, such as Figure 3 As shown, the inner wall surface of the mounting cavity 111 is curved, as... Figure 6 As shown, both the first limiting rib 23 and the second limiting rib 24 have a clearance slope 28 on the side away from the outer wall of the mounting cylinder 211, such as... Figure 8As shown, the avoidance slope 28 has a third side 281 and a fourth side 282 opposite to each other along its inclined direction. The third side 281 is closer to the limiting groove 221 than the fourth side 282, and the fourth side 282 is closer to the outer wall of the mounting cylinder 211 than the third side 281. In this way, the first limiting rib 23 and the second limiting rib 24 can avoid the inner wall surface of the mounting cavity 111 by avoiding the avoidance slope 28, thus avoiding the first limiting rib 23 and the second limiting rib 24 interfering with the inner wall surface of the mounting cavity 111 and causing assembly difficulties.

[0049] Optionally, in one embodiment, such as Figure 3 or Figure 4 As shown, the mounting cavity 111 has a insertion opening 112 for inserting the second housing 21. The limiting block 121 has a bottom wall 1211 facing the insertion opening 112 and side walls 1212 connected to both sides of the bottom wall 1211. A guide arc surface 1213 connects the bottom wall 1211 and the side walls 1212. Specifically, in this embodiment, the limiting block 121 is generally rectangular in shape. Therefore, the limiting block 121 has a bottom wall 1211 facing the insertion opening 112 and side walls 1212 connected to both sides of the bottom wall 1211. The two side walls 1212 correspond to the first limiting rib 23 and the second limiting rib 24, respectively. Crucially, a guide arc surface 1213 connects the bottom wall 1211 and each side wall 1212. When the first limiting rib 23 or the second limiting rib 24 abuts against the guide arc surface 1213 due to positional deviation, the first limiting rib 23 or the second limiting rib 24 can gradually move to the outside of the side wall 1212 under the guidance of the guide arc surface 1213, so that the limiting block 121 can slide into the limiting groove 221 more smoothly, improving assembly efficiency.

[0050] Optionally, in one embodiment, the limiting block 121 is integrally formed with the inner wall of the mounting cavity 111, so that the limiting block 121 can be stably located in the mounting cavity 111, avoiding the situation where the battery assembly 20 is also unstable due to the unstable installation of the limiting block 121 itself, thereby improving the assembly stability between the battery assembly 20 and the atomizing assembly 10.

[0051] It should be noted that when the limiting block 121 is integrally formed with the inner wall of the mounting cavity 111, the limiting block 121 can be formed by protrusions on the inner wall of the mounting cavity 111, or the first housing 11 can be recessed into the mounting cavity 111 to form the limiting block 121.

[0052] For example, optionally, in one embodiment, please combine Figure 3 and Figure 5The first housing 11 is recessed into the mounting cavity 111 to form a limiting block 121 and a recessed area 113. The recessed area 113 is recessed relative to the outer wall of the first housing 11 and a display (not shown) is mounted thereon. That is, in this embodiment, the portion of the first housing 11 that is recessed into the mounting cavity 111 is used to limit the first housing 11 and the second housing 21, and is also used to mount the display, achieving a "multi-functional structure" effect, thereby simplifying the structure of the aerosol generator 100.

[0053] Optionally, in one embodiment, please combine Figure 1 , Figure 3 and Figure 5 One end of the mounting cavity 111 is provided with a plug-in opening 112 for inserting the second housing 21. The first housing 11 is provided with a notch 114 communicating with the plug-in opening 112. The notch 114 is disposed opposite to the limiting block 121, and part of the mounting cylinder 211 protrudes out of the mounting cavity 111 through the notch 114. Specifically, because the limiting block 121 is provided inside the mounting cavity 111, the limiting block 121 occupies a certain space inside the mounting cavity 111, so the battery cannot be made larger, affecting the overall power of the aerosol generator 100. Therefore, in order to solve the above technical problems, in this embodiment, a notch 114 is provided on the side wall 1212 of the first housing 11. The notch 114 is disposed opposite to the limiting block 121 and communicates with the plug-in opening 112, and part of the mounting cylinder 211 for mounting the battery protrudes out of the mounting cavity 111 through the notch 114.

[0054] It is understandable that the part of the mounting cylinder 211 that protrudes outside the mounting cavity 111 through the notch 114 can compensate for the space occupied by the limiting block 121, so that the battery will not be limited to a smaller size due to the setting of the limiting block 121, and the overall power of the aerosol generator 100 is guaranteed.

[0055] Optionally, in one embodiment, such as Figure 1 and Figure 2 As shown, one of the first housing 11 and the second housing 21 is provided with a locking hole 115, and the other is provided with a latch 213. The latch 213 is engaged in the locking hole 115 to restrict the relative movement of the first housing 11 and the second housing 21 in the insertion and removal direction. Specifically, in this embodiment, the first housing 11 is provided with a locking hole 115, which is a through hole and communicates with the mounting cavity 111. The second housing 21 also includes a base plate 214, on which the latch 213 is provided. When the second housing 21 is inserted into the first housing 11, the latch 213 is engaged in the locking hole 115, thereby restricting the relative movement of the first housing 11 and the second housing 21 in the insertion and removal direction.

[0056] Of course, in other embodiments, a buckle 213 may be provided on the first housing 11 and a locking hole 115 may be provided on the second housing 21, which can also achieve the limiting of the first housing 11 and the second housing 21 in the insertion and removal direction.

[0057] In addition, the number of buckles 213 and buckle holes 115 can be flexibly set according to actual needs. For example, the number of buckles 213 can be two, three, four, five, six, etc., and the number of buckle holes 115 corresponds one-to-one with the number of buckles 213.

[0058] Optionally, in one embodiment, such as Figure 6 As shown, the second limiting structure 22 is disposed on the outer wall of the second housing 21, and the buckle 213 is disposed on the second housing 21, with buckles 213 respectively provided on both sides of the second limiting structure 22. Specifically, in this embodiment, the second housing 21 includes a base plate 214 and a mounting cylinder 211 connected to the base plate 214. Two buckles 213 are provided, each buckle 213 is connected to the base plate 214, and each buckle 213 includes a pressing part 2131 and a fastening part 2132. The pressing part 2131 is fixedly connected to the base plate 214, and the fastening part 2132 is located on the side of the mounting part away from the base plate 214, and the fastening part 2132 is used to fasten into the buckle hole 115. Crucially, in this embodiment, the two latches 213 are located on both sides of the second limiting structure 22. This allows the assembler to press the latches 213 while observing the second limiting structure 22 during assembly, which makes it easier to accurately find the insertion angle of the second housing 21 and improves assembly efficiency.
