Description

Technical Field

[0001] This application relates to the field of aerosol generating device technology, and more specifically, to an atomizer structure and an aerosol generating device. Background Technology

[0002] With the development of aerosol generating devices, existing single-tank aerosol generating devices are gradually unable to meet the growing demand for diverse flavors from users. Therefore, multi-tank aerosol generating devices have emerged on the market.

[0003] In multi-compartment aerosol generators, multiple compartments are typically stacked sequentially along their height, with through-holes connecting them. In existing technologies, before the user uses the aerosol generator, some compartments are already connected. This can lead to premature mixing of liquids between compartments, affecting the final aerosol's flavor; or, the liquid may concentrate at the bottom and contact the atomizer core, causing leakage and impacting the generator's lifespan. Other aerosol generators employ a separate design, placing the compartments separately within the liquid cartridge and the main body containing the atomizer core. This design requires the user to assemble the main body and cartridge before vaping and remove the seal between them, resulting in low assembly efficiency, a poor user experience, and the risk of leakage due to improper handling during assembly.

[0004] In summary, existing aerosol generating devices suffer from problems such as leakage, low assembly efficiency, and low utilization efficiency. Utility Model Content

[0020] When the limiting member restricts the first body and the second body, at least a portion of the first positioning protrusion is located in the first positioning groove, and the first connecting protrusion and the first connecting hole are separated.

[0021] When the limiting member separates from the first body and the second body, and the liquid inlet pipe lifts the sealing part to connect the first receiving cavity and the second receiving cavity, the first connecting protrusion engages with the first connecting hole.

Detailed Implementation

[0045] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.

[0046] In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its actual use or operating state, specifically the orientation shown in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "comprising" means "including but not limited to". The terms first, second, third, etc., are used merely as illustrative purposes and do not impose numerical requirements or establish a numerical order.

[0047] In this application, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. A and B can be singular or plural.

[0048] In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, "at least one of a, b, or c," or "at least one of a, b, and c," can both mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be single or multiple.

[0049] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0050] Please refer to Figures 1-4 This application also provides an atomizer structure, including:

[0051] A first main body 100, wherein a first receiving cavity 101 is provided inside the first main body 100;

[0052] The second main body 200 has a second receiving cavity 201 inside it;

[0053] A sealing assembly 400 is used to seal the first receiving cavity 101. It is provided with a sealing hole 401 and a sealing part 430. The sealing hole 401 connects the first receiving cavity 101 to the external environment. The sealing part 430 is interference-fitted with the sealing hole 401 to seal the sealing hole 401.

[0054] The liquid inlet pipe 230 has one end connected to the first receiving cavity 101 and the other end connected to the sealing hole 401.

[0055] The limiting member 300 is engaged between the first body 100 and the second body 200 to restrict the relative movement of the first body 100 and the second body 200, so as to restrict the liquid inlet pipe 230 from abutting the sealing part 430 until the sealing part 430 leaves the sealing hole 401.

[0056] In this embodiment, the limiting member 300 can restrict the first body 100 and the second body 200 from moving closer together along the Z direction in the figure. Therefore, when the user needs to activate the atomizer structure or the aerosol generating device containing the atomizer structure, the usage process is as follows: First, remove the limiting member 300 to release the movement restriction of the limiting member 300 on the first body 100 and the second body 200; then, drive the first body 100 and the second body 200 to move closer together (for example, press the first body 100 toward the second body 200), so that the liquid inlet tube 230 continuously abuts against the sealing part 430 until the sealing part 430 leaves the sealing hole 401; after the sealing part 430 leaves the sealing hole 401, the sealing hole 401 opens, and the first receiving cavity 101 and the second receiving cavity 201 are connected.

[0057] The atomizer structure of this embodiment can maintain isolation between multiple chambers before activation to prevent liquid leakage. At the same time, because the multiple chambers are not connected, the internal air pressure is stable, and the liquid in the multiple chambers will not flow to the atomizer core assembly 500 and other parts on its own, thereby further preventing liquid leakage or short circuit of internal components and improving the service life of the atomizer structure. Then, the connection and conduction between the multiple chambers can be completed by pressing the first main body 100 and the second main body 200. It is simple to use, so it is highly efficient and less prone to leakage due to improper operation.

[0058] In summary, the atomizer structure of this embodiment can effectively prevent leakage, improve its service life, and has a long service life.

[0059] Further, please refer to Figures 1-5 The limiting member 300 has a first mounting groove 301 and a second mounting groove (not shown in the figure) respectively at its two opposite ends. The end of the first body 100 facing the second body 200 is located in the first mounting groove 301, and the end of the second body 200 facing the first body 100 is located in the second mounting groove.

[0060] The vertical distance from the bottom of the first mounting groove 301 to the bottom of the second mounting groove is the first distance, and the vertical distance from the end of the liquid inlet pipe 230 facing the first receiving cavity 101 to the opening of the sealing hole 401 is the second distance. The first distance is greater than the second distance.

[0061] In this embodiment, the first mounting groove 301 and the second mounting groove respectively fix the first body 100 and the second body 200 to prevent the first body 100 and the second body 200 from slipping off the limiting member 300. The first distance is the distance that the first body 100 and the second body 200 can approach each other after the limiting member 300 is disengaged. Therefore, when the first distance is greater than the second distance, it can be ensured that before the first body 100 is connected to the second body 200, the liquid inlet pipe 230 can complete the action of pushing the sealing part 430 to move away from the sealing hole 401, thereby preventing the liquid inlet pipe 230 from failing to connect the first receiving cavity 101 and the second receiving cavity 201 after the user presses the first body 100.

[0062] Further, please refer to Figures 1-2 and Figure 6 The side wall of the limiting member 300 is provided with a gripping protrusion 310 and a disassembly opening 320. The disassembly opening 320 and the gripping protrusion 310 are arranged opposite to each other, and the disassembly opening 320 connects the first mounting groove 301 and the second mounting groove.

[0063] Furthermore, the limiting member 300 is provided with a clearance hole 330, and the disassembly opening 320 communicates with the clearance hole 330; and / or,

[0064] The limiting member 300 is an elastic member, and the disassembly opening 320 is smaller than the diameter of the first body 100 and / or the second body 200.

[0065] In this embodiment, the gripping protrusion 310 is provided for the user to grip, so as to control the limiting member 300 to move away from the first body 100 and the second body 200 along the X direction in the figure, thereby improving the user's efficiency. The disassembly opening 320 is disposed opposite to the gripping protrusion 310. Therefore, when the user controls the gripping protrusion 310 to drive the limiting member 300 to move along the X direction, the disassembly opening 320 allows the first body 100 and the second body 200 to separate from the limiting member 300 through the disassembly opening 320.

[0066] The clearance hole 330 allows the limiting member 300 to avoid structural elements (such as the liquid inlet pipe 230 and the vent pipe 240) between the first body 100 and the second body 200 after assembly with the first body 100 and the second body 200, thereby preventing collisions between the limiting member 300 or the structures between the first body 100 and the second body 200 that could affect installation accuracy. It should be understood that the sealing assembly 400 and the limiting member 300 can be made of silicone.

[0067] Further, please refer to Figures 3-5 , Figures 8-9 The sealing assembly 400 also includes a sealing body 410 and a connecting part 420. A sealing hole 401 is disposed in the sealing body 410, and one end of the connecting part 420 is connected to the sealing body 410 and the other end is connected to the sealing part 430.

[0068] In this embodiment, the connecting part 420 can connect the sealing part 430 and the sealing body 410 to prevent the sealing part 430 from floating in the first receiving cavity 101 after being held away from the sealing hole 401 by the liquid inlet pipe 230, so as to affect the quality of the liquid in the first receiving cavity 101; at the same time, it can also prevent the sealing part 430 from flowing with the liquid in the first receiving cavity 101 to block the opening of the liquid inlet pipe 230.

[0069] Further, please refer to Figures 3-5 , Figure 7 The first body 100 includes a first outer shell 120 and a bottom cover 110. The first outer shell 120 and the bottom cover 110 define a first receiving cavity 101. The bottom cover 110 is provided with a first positioning protrusion 111 on the side facing the second body 200. The side wall of the first positioning protrusion 111 is provided with a first connecting protrusion 112. The second body 200 includes a liquid cup 210. The liquid cup 210 is provided with a second receiving cavity 201. The side of the liquid cup 210 facing the first body 100 is provided with a first positioning groove 212. The side wall of the first positioning groove 212 is provided with a first connecting hole 211.

[0070] When the limiting member 300 restricts the first body 100 and the second body 200, at least part of the first positioning protrusion 111 is located in the first positioning groove 212, and the first connecting protrusion 112 and the first connecting hole 211 are separated.

[0071] When the limiting member 300 separates from the first body 100 and the second body 200, and the liquid inlet pipe 230 pushes up the sealing part 430 to connect the first receiving cavity 101 and the second receiving cavity 201, the first connecting protrusion 112 engages with the first connecting hole 211.

[0072] In this embodiment, since at least a portion of the first positioning protrusion 111 is located within the first positioning groove 212 when the limiting member 300 is connected to the first body 100 and the second body 200, after the limiting member 300 disengages, the first positioning protrusion 111 can guide the first body 100 and the second body 200 to complete the installation quickly and accurately. After the first body 100 moves toward the second body 200, the first connecting protrusion 112 can engage with the first connecting hole 211, thereby completing the installation of the first body 100 and the second body 200, making it difficult for the first body 100 and the second body 200 to separate, thus improving the stability of the atomizer structure.

[0073] Further, please refer to Figure 2 and Figure 7 The outer side wall of the bottom cover 110 is also provided with a second connecting protrusion 113, and the side wall of the first outer shell 120 is provided with a second connecting hole 121. The second connecting protrusion 113 is engaged with the second connecting hole 121.

[0074] For further details, please refer to... Figure 1 , Figure 3 , Figure 5 , Figures 6-8 The bottom cover 110 has a second positioning protrusion 114 on the side facing the sealing assembly 400, and the sealing assembly 400 has a second positioning groove 402 on the side facing the bottom cover 110. The second positioning groove 402 is arc-shaped, and the second positioning protrusion 114 is installed in the second positioning groove 402 and is adapted to the second positioning groove 402; and / or,

[0075] There are multiple first positioning protrusions 111 and multiple first positioning grooves 212, and the multiple first positioning protrusions 111 and multiple first positioning grooves 212 are arranged in a one-to-one correspondence; and / or,

[0076] The first outer casing 120 is a transparent part.

[0077] In this embodiment, because the second positioning groove 402 is arc-shaped and the second positioning protrusion 114 is adapted to the second positioning groove 402, the second positioning protrusion 114 can only be installed into the second positioning groove 402 at a preset angle. Therefore, the cooperation between the second positioning protrusion 114 and the second positioning groove 402 can guide the installation of the bottom cover 110 and the sealing assembly 400, and also play a foolproof role. When there are multiple first positioning protrusions 111 and first positioning grooves 212, relative rotation between the first body 100 and the second body 200 can be avoided when the limiting member 300 is not disengaged. When the first outer shell 120 is a transparent part, it is convenient for the user to observe the remaining liquid in the first receiving cavity 101 and whether the sealing part 430 is blocked in the sealing hole 401 through the first outer shell 120, thereby improving the user's efficiency.

[0078] Further, please refer to Figures 1-5 The second body 200 includes a liquid cup 210 and a second outer shell 220. The second receiving cavity 201 is disposed in the liquid cup 210. The second outer shell 220 is provided with a third receiving cavity 10. The liquid cup 210 is located in the third receiving cavity 10 and can reciprocate along the third receiving cavity 10 toward the first body 100.

[0079] When the limiting member 300 restricts the first body 100 and the second body 200, there is a gap between the liquid cup 210 and the bottom wall of the third receiving cavity 10;

[0080] When the limiting member 300 separates from the first body 100 and the second body 200, and the liquid inlet pipe 230 lifts the sealing part 430 to connect the first receiving cavity 101 and the second receiving cavity 201, the liquid cup 210 abuts against the bottom wall of the third receiving cavity 10, and at least part of the first body 100 is located in the third receiving cavity 10.

[0081] In this embodiment, when the limiting member 300 is not disengaged, it prevents the first body 100 from moving towards the second body 200. When the limiting member 300 disengages from between the first body 100 and the second body 200, the first body 100 moves towards the second body 200. At this time, the liquid cup 210 will be forced to move towards the bottom wall of the third receiving cavity 10. After the bottom of the liquid cup 210 abuts against the bottom wall of the third receiving cavity 10, the liquid cup 210 stops moving, and the first body 100 is connected to the liquid cup 210. The specific connection method can be referred to the first positioning protrusion 111, the first positioning groove 212, the first connecting protrusion 112, and the first connecting hole 211 in the above embodiment.

[0082] After the first body 100 moves toward the second body 200, part of the first body 100 will also be located in the third receiving cavity 10. At this time, the connection between the first body 100 and the liquid cup 210 can be prevented from being exposed, thereby preventing accidental disconnection of the connection and improving the stability of the multi-compartment preset structure.

[0083] It should be understood that the first body 100 can be interference-fitted with the third receiving cavity 10 so that the first body 100 is less likely to detach after entering the third receiving cavity 10, thereby improving the stability of the atomizer structure. The limiting member 300 can abut against the opening end of the third receiving cavity 10 to prevent the second body 200 and the first body 100 from moving toward the bottom wall of the third receiving cavity 10, or it can be glued to the side wall of the third receiving cavity 10 so that it will detach from the preset position after being subjected to a certain force, or it can be fixed to the inner wall of the second outer shell 220 by a mechanical mechanism such as a buckle.

[0084] Further, please refer to Figures 3-5 The first main body 100 is provided with a suction channel 102, and the second main body 200 is provided with an atomizing core assembly 500. An air outlet pipe 240 is provided on the side facing the first main body 100. One end of the air outlet pipe 240 is connected to the atomizing core assembly 500, and the other end passes through the suction channel 102.

[0085] In this embodiment, the air outlet pipe 240 can connect the air passage of the first body 100 and the second body 200 so that the gas and aerosol in the first body 100 and the second body 200 can be smoothly drawn in by the user; at the same time, the air outlet pipe 240 can also guide the connection of the first body 100 and the second body 200 and prevent the first body 100 and the second body 200 from separating along the X direction in the figure.

[0086] Accordingly, please refer to Figures 1-5 This application also provides an aerosol generating device, which includes the atomizer structure of any of the above embodiments.

[0087] In this embodiment, the aerosol generating device includes the atomizer structure of the previous embodiment. Therefore, before activation, it can maintain stable air pressure between multiple chambers and prevent liquid from flowing on its own, thus avoiding liquid leakage or short circuits in internal components and improving the service life of the atomizer structure. Simultaneously, the connection and conduction between multiple chambers can be completed simply by pressing, resulting in high efficiency and reducing the likelihood of leakage due to improper operation. In summary, the aerosol generating device of this embodiment effectively avoids leakage, improves its own service life, and has a long service life.
