Description

Technical Field

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

[0002] Aerosol generating devices typically have an internal gas path structure, which includes a suction channel and a heating element. Users can draw air from the aerosol generating device, causing the aerosol generating medium within the gas path structure to come into contact with the heating element, thereby generating aerosols. The aerosols then flow through the suction channel for the user to inhale.

[0003] Existing aerosol generating devices include mouth-inhalation aerosol generating devices and lung-inhalation aerosol generating devices. When inhaling through the mouth, the aerosol needs to remain in the mouth for a period of time before being inhaled into the lungs; therefore, the airflow structure of mouth-inhalation aerosol generating devices has a small airflow. When inhaling through the lungs, the aerosol needs to enter the lungs directly; therefore, the airflow structure of lung-inhalation aerosol generating devices has a large airflow.

[0004] The air path structure of existing aerosol generating devices is fixed, so they cannot simultaneously support both mouth-to-mouth and lung-to-lung inhalation modes. This forces users to carry two aerosol generating devices at the same time, which reduces the efficiency of the aerosol generating devices and the user experience. Utility Model Content

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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] To solve the above problems, please refer to... Figures 1-5 This application provides a gas path structure, which includes: a main body, the main body being provided with a suction channel 11 and a first air inlet 210 respectively connected to the external environment, the first air inlet 210 being connected to the suction channel 11;

[0056] An adjustment component 100 is rotatably connected to the main body and is provided with a first through hole 110. The adjustment component 100 is used to rotate to make the first through hole 110 and the first air inlet 210 connected or misaligned, so as to block or open the first air inlet 210.

[0057] In this embodiment, the adjusting component 100 can rotate to control the connection or misalignment of the first through hole 110 and the first air inlet 210. Therefore, by controlling the rotation amplitude of the adjusting component 100, the conduction area of ​​the first air inlet 210 can be controlled, thereby changing the air volume in the suction channel 11 when the user inhales, achieving the purpose of switching between mouth inhalation and lung inhalation. Therefore, the airway structure of this embodiment enables the user to use the aerosol generating device efficiently and has a good user experience.

[0058] Further, please refer to Figures 1-5 The main body includes a first outer shell 10 and a first sealing element 200. A second through hole is provided inside the first outer shell 10. The adjusting component 100 passes through the second through hole and is interference-fitted with the second through hole.

[0059] The first sealing member 200 is located inside the first housing 10 and abuts against the inner wall of the first housing 10 where the second through hole is provided. The first sealing member 200 is provided with a first air inlet 210 communicating with the second through hole. Along the air intake direction of the first air inlet 210, the projected area of ​​the first air inlet 210 is smaller than the projected area of ​​the second through hole.

[0060] When the adjusting component 100 rotates, the first through hole 110 is misaligned or connected with the first air inlet 210.

[0061] In this embodiment, the adjustment component 100 is inserted through the second through hole along the Z direction in the figure to connect itself and the first outer shell 10. The user can drive the adjustment component 100 to rotate around the Z axis in the figure by moving the end of the adjustment component 100 away from the main body. The first sealing member 200 can change the conduction area of ​​the second through hole. Since the projected area of ​​the first air inlet 210 is smaller than that of the second through hole, when the adjustment component 100 rotates and the first through hole 110 on it intersects with the first air inlet 210, external gas can smoothly enter from the first air inlet 210; when the first through hole 110 and the first air inlet 210 are misaligned, the adjustment component 100 will block the first air inlet 210, preventing gas from entering the interior of the first outer shell 10.

[0062] Therefore, the adjustment component 100, the first seal 200 and the first housing 10 of the air passage structure in this embodiment can form a simple and easy-to-control mechanical structure, which makes it convenient for users to operate, adjust and control the air output of the air passage structure.

[0063] Further, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 The air passage structure includes a first sub-body 600 and a second sub-body 700 connected to each other. The first sub-body 600 is provided with an atomizing core assembly 13, a mouthpiece 12 and a first air tube 20. The mouthpiece 12 passes through the first sub-body 600 and is connected to the inside of the atomizing core assembly 13 to form a suction channel 11.

[0064] The second sub-body 700 is provided with a microphone 60. One end of the first air tube 20 is connected to the microphone 60, and the other end is connected to the mouthpiece 12 and the atomizing core assembly 13 to connect the microphone 60 and the suction channel 11.

[0065] In this embodiment, when the user inhales, the airflow structure generates an airflow through the microphone 60, which triggers the atomizing core assembly 13 to operate. The airflow intake path is as follows: Figure 1 As indicated by the middle arrow.

[0066] The separate design of the first sub-body 600 and the second sub-body 700 prevents the aerosol-generating medium inside the first sub-body 600 from entering the second sub-body 700, thereby preventing circuit components such as the microphone 60 located in the second sub-body 700 from being soaked and malfunctioning due to the aerosol-generating medium. Simultaneously, the first air pipe 20 guides the airflow, preventing some of the airflow flowing through the microphone 60 from entering the first air pipe 20 and... Figure 1 The airflows indicated by the arrows converge, thus avoiding Figure 1 The airflow in the middle and the airflow through the microphone 60 create a counterforce, thereby improving the sensitivity of the microphone 60 and the airflow volume of the air path structure. Because one end of the first air tube 20 is connected between the atomizing core assembly 13 and the mouthpiece 12, when Figure 1 When the airflow flows, it will not come into contact with the hot airflow inside the atomizing core assembly 13, thus avoiding the influence of the hot airflow. Figure 1 Airflow within the microphone is adjusted to improve the sensitivity of the microphone 60.

[0067] Further, please refer to Figure 1 , Figure 2 , Figures 6-11 The first sub-body 600 has a second air inlet 17 at the end away from the mouthpiece 12. The second sub-body 700 has a second sealing element 500, which is located between the microphone 60 and the first sub-body 600. An elastic ring 520 is provided on the side of the second sealing element 500 facing the first sub-body 600. The elastic ring 520 abuts against the first sub-body 600. Along the direction from the first sub-body 600 to the second sub-body 700, the second air inlet 17 is located inside the elastic ring 520 and is used to connect the first air tube 20 and the microphone 60.

[0068] In this embodiment, since the second sealing member 500 is disposed between the microphone 60 and the first sub-body 600, the second sealing member 500 can further seal the microphone 60, preventing liquid from flowing directly from the second air inlet 17 to the surface of the second sub-body 700, thereby improving the service life of the second sub-body 700 (including the microphone 60); at the same time, the elastic ring 520 abuts against the first sub-body 600, and the second air inlet 17 is located inside the elastic ring 520 along the direction from the first sub-body 600 to the second sub-body 700. Therefore, when the first sub-body 600 and the second sub-body 700 are connected, the second air inlet 17 will be sealed by the elastic ring 520, thereby further preventing the second sub-body 700 and the microphone 60 from contacting the liquid.

[0069] It should be understood that the gas path structure may also include a first liquid-absorbing element (not shown in the figure), which is located between the elastic ring 520 and the first sub-body 600. In this case, the first liquid-absorbing element can absorb liquid from the first sub-body 600, thereby preventing liquid from accumulating on the surface of the second seal 500 and flowing to the microphone 60.

[0070] Further, please refer to Figures 7-11 The second sealing element 500 is provided with a second air pipe 510, which passes through the second air inlet 17. The side wall of the second air pipe 510 is provided with a fourth through hole 512, which connects the second air pipe 510 and the first air pipe 20.

[0071] In this embodiment, since the second air tube 510 is connected to the first air tube 20 through the fourth through hole 512 provided on its side wall, even if there is some gas backflow in the first air tube 20 and liquid condenses on the top wall of the second air inlet 17 above the second air tube 510, the liquid cannot enter the fourth through hole 512 when it falls, thereby preventing the microphone 60 from being soaked in liquid and improving the service life of the air circuit structure.

[0072] It should be understood that the second air tube 510 can be a separate component, in which case the second air tube 510 and the second seal 500 are connected by assembly, thus allowing the user to quickly replace the second air tube 510 and improve the maintenance efficiency of the air circuit structure. Alternatively, the second air tube 510 can be integrally formed with the second seal 500, in which case the connection between the second air tube 510 and the second seal 500 is reliable and has higher strength.

[0073] It should be understood that the second air inlet 17 is set in the Z direction in the figure, and the fourth through hole 512 can be set in the X direction in the figure. That is, the setting direction of the fourth through hole 512 is perpendicular to the setting direction of the second air inlet 17. Therefore, when the gas in the second air inlet 17 condenses into liquid and falls, it cannot directly enter the fourth through hole 512.

[0074] It should be understood that the depth direction (X-axis direction) of the fourth through hole 512 can be oriented away from the first air pipe 20. In this case, when the aerosol or other airflow in the first air pipe 20 flows to the second air pipe 510, it cannot directly pass through the fourth through hole 512. Instead, it first contacts the second air inlet 17 and the outer wall of the second air pipe 510, and then condenses to form a liquid. This liquid will remain between the second air inlet 17 and the second seal 500. Therefore, with the depth direction of the fourth through hole 512 in this embodiment oriented away from the first air pipe 20, it can effectively prevent externally flowing gas from entering the second air pipe 510, thereby preventing this gas or liquid from contacting the microphone 60 and improving the service life of the microphone 60.

[0075] Further, please refer to Figures 1-6 The air passage structure also includes a first sealing element 200. The inner wall of the first sub-body 600 is provided with a partition plate 16. The first sealing element 200 abuts against the partition plate 16 and the end of the atomizing core assembly 13 near the mouthpiece 12, and forms a first receiving cavity 30 between the first sealing element 200, the partition plate 16 and the atomizing core assembly 13. A first gap 41 is provided between the mouthpiece 12 and the atomizing core assembly 13. The first gap 41 connects the first receiving cavity 30 and the suction channel 11.

[0076] One end of the first air tube 20 passes through the first seal 200 and is located in the first receiving cavity 30. The first seal 200 is provided with a first inclined surface 220, which is located in the first receiving cavity 30. The first inclined surface 220 is connected to the first gap 41, and the vertical distance between the first inclined surface 220 and the microphone 60 gradually increases in the direction away from the first gap 41.

[0077] In this embodiment, the first receiving cavity 30 can prevent the aerosol medium in the first sub-body 600 from flowing back into the first air tube 20 when shaken, thereby preventing liquid from submerging the microphone 60; the direction away from the first gap 41 is the X direction in the figure, and the vertical distance between the first inclined surface 220 and the microphone 60 is the distance in the Z direction in the figure. When a portion of the aerosol in the suction channel 11 condenses and flows back to the first gap 41, and flows along the first gap 41 into the first receiving cavity 30, the first inclined surface 220 can prevent this portion of liquid from accumulating in the first receiving cavity 30, and at the same time guide this portion of liquid to flow back to the first gap 41 along the first inclined surface 220, and then flow back into the suction channel 11, thereby preventing the microphone 60 from being submerged by liquid, and reducing the loss rate of the aerosol generating medium.

[0078] Please refer to Figures 6-8 In the gas path structure, the third sealing element 800 is provided with a first receiving groove and a fifth through hole 810, and the microphone 60 is located in the first receiving groove;

[0079] The second sealing member 500 is provided with a second receiving groove 530 and a second air pipe 510. The third sealing member 800 is located in the second receiving groove 530. The third sealing member 800 and the second receiving groove 530 define a receiving cavity. Along the depth direction of the fifth through hole 810 (Z direction in the figure), the orthographic projections of the fifth through hole 810 and the second air pipe 510 are misaligned.

[0080] In this embodiment, firstly, the microphone 60 passes through the gas passage formed by the fifth through hole 810, the receiving cavity, and the second air tube 510, so that when the user inhales, the gas can travel along... Figure 1The liquid flows through the microphone 60 in the direction of the middle arrow, thereby activating the aerosol generating device containing the gas path structure. Secondly, the third seal 800 effectively accommodates and restricts the movement of the microphone 60, while the second seal 500 accommodates and restricts the third seal 800, thus ensuring high stability of the gas path structure. Then, along the Z direction in the figure, the orthographic projections of the fifth through hole 810 and the second air pipe 510 are misaligned. Therefore, when external liquid passes through the second air pipe 510, it cannot drip directly into the fifth through hole 810, thereby preventing liquid from directly passing through the fifth through hole 810 and contacting the microphone 60, thus improving the service life of the gas path structure. In summary, the gas path structure of this embodiment has strong stability, long service life, and good performance.

[0081] Furthermore, such as Figure 5 and Figure 6 As shown, the top of the first trachea 20 can also form a second gap 42 with the inner wall of the first outer shell 10, and along the Z direction in the figure, the second gap 42 is higher than the first gap 41.

[0082] In this embodiment, when the user inhales, the gas in the first receiving cavity 30 will flow through the first gap 41 to the suction channel 11, thereby forming a negative pressure. The negative pressure will cause the gas in the first air tube 20 to flow through the second gap 42 into the first receiving cavity 30, and then through the first gap 41 into the suction channel 11 for the user to inhale.

[0083] First, because the height of the second gap 42 is greater than the height of the first gap 41, even if the aerosol in the suction channel 11 enters the first receiving cavity 30 through the first gap 41, it cannot directly enter the first air tube 20. Instead, after contacting the side wall of the first air tube 20, it condenses into liquid and slides down to the bottom wall of the first receiving cavity 30. In summary, the design of the second gap 42 in this embodiment can prevent external gas from flowing back into the first air tube 20, thereby preventing the microphone 60 from being corroded by liquid and improving the sensitivity of the microphone 60.

[0084] Secondly, the second gap 42 allows the gas in the first air tube 20 to flow accordingly with the user's suction, thereby promoting the flow of gas through the microphone 60 and improving the detection accuracy of the microphone 60. At the same time, since the second gap 42 is located at the top of the first receiving cavity 30, the gas in the first air tube 20 will compress the first receiving cavity 30 to a certain extent after passing through the second gap 42, thereby causing the liquid (partially formed by the condensation of aerosol) located at the bottom of the first receiving cavity 30 to flow towards the first gap 41 into the suction channel 11, so as to avoid the accumulation of this part of the liquid and improve the utilization rate of the aerosol generating medium.

[0085] Then, the width of the second gap 42 (in the Z-axis direction) can be set to be smaller than the width of the first gap 41. In this case, it is possible to further prevent the gas entering the first receiving cavity 30 from the first gap 41 from flowing back into the first air tube 20, so as to avoid the microphone being corroded by liquid.

[0086] Further, please refer to Figure 1 , Figure 5 The first air tube 20 can abut against the inner wall of the first outer shell 10. At this time, the side wall of the first air tube 20 is provided with an opening, which is located in the first receiving cavity 30 and on the side of the first air tube 20 away from the first gap 41.

[0087] In this embodiment, the opening allows airflow that flows through the microphone 60 into the first trachea 20 to pass through, so that the airflow can enter the first receiving cavity 30 from the first trachea 20, and then pass through the first gap 41 from the first receiving cavity 30 into the suction channel 11.

[0088] Because the opening is located on the side of the first air tube 20 away from the first gap 41, even if the aerosol in the suction channel 11 passes through the first gap 41 and flows back into the first receiving cavity 30, this portion of the aerosol cannot directly enter the opening. Instead, it first adheres to the side wall of the first air tube 20 or the inner wall of the first outer shell 10, forming a liquid such as an aerosol generating medium. This liquid flows along the side wall of the first air tube 20 or the inner wall of the first outer shell 10 under the action of gravity to the bottom wall of the first receiving cavity 30. Therefore, the technical solution of the first air tube 20 abutting against the inner wall of the first outer shell 10 and having an opening can prevent liquid from entering the microphone. At the same time, because the first air tube 20 abuts against the inner wall of the first outer shell 10, the first outer shell 10 can prevent the first air tube 20 from shaking through friction, thereby improving the stability of the air path structure and thus increasing the service life of the aerosol generating device.

[0089] It should be understood that when the first air tube 20 abuts against the inner wall of the first outer shell 10, the first air tube 20 can be integrally formed with the inner wall of the first outer shell 10. At this time, the connection strength between the first air tube 20 and the first outer shell 10 is high.

[0090] Further, please refer to Figures 6-8 The third sealing element 800 is provided with a second inclined surface 830. Along the depth direction of the fifth through hole 810 (Z direction in the figure), the orthographic projection of the second air tube 510 is located on the second inclined surface 830. One end of the second inclined surface 830 is connected to the side of the fifth through hole 810 away from the microphone 60, and along the direction away from the fifth through hole 810 (X direction in the figure), the vertical distance between the second inclined surface 830 and the second air tube 510 gradually increases.

[0091] In this embodiment, along the Z direction in the figure, the orthographic projection of the second air tube 510 is located on the second inclined surface 830. Therefore, when liquid flows into the receiving cavity from the second air tube 510, the liquid will move along the inclined direction of the second inclined surface 830. Along the direction away from the fifth through hole 810, the vertical distance between the second inclined surface 830 and the second air tube 510 gradually increases. Therefore, when liquid falls onto the second inclined surface 830, it will move away from the fifth through hole 810, thereby effectively preventing liquid from entering the fifth through hole 810 and contacting the microphone 60. In summary, the microphone 60 of this embodiment has a long service life and good performance.

[0092] Further, please refer to Figure 7 The gas path structure also includes a second liquid suction element 70, and the third sealing element 800 is also provided with a third receiving groove 840. The groove opening of the third receiving groove 840 is connected to the end of the second inclined surface 830 away from the fifth through hole 810.

[0093] In this embodiment, the opening of the third receiving groove 840 is connected to the end of the second inclined surface 830 away from the fifth through hole 810. Therefore, when liquid drips onto the second inclined surface 830, it will flow along the second inclined surface 830 to the third receiving groove 840 and finally contact the second liquid suction member 70 in the third receiving groove 840. The second liquid suction member 70 will store and absorb the liquid to prevent the liquid from flowing back to the microphone 60 when the user shakes the air passage structure (when the user shakes the aerosol generating device).

[0094] It should be understood that the second absorbent element 70 can be an oil-absorbing cotton.

[0095] Further, please refer to Figure 7 The first receiving groove includes a first sub-receiving groove and a second sub-receiving groove 820. The first sub-receiving groove is disposed at the bottom of the second sub-receiving groove 820. The fifth through hole 810 connects to the first sub-receiving groove. The microphone 60 is located inside the second sub-receiving groove 820 and is interference-fitted with the second sub-receiving groove 820.

[0096] In this embodiment, the interference fit between the microphone 60 and the second sub-receiving groove 820 can prevent the microphone 60 from shifting position during operation. The first sub-receiving groove allows the gas to still have a large flow channel after passing through the fifth through hole 810, thereby allowing the microphone 60 to contact a larger volume of gas and improve the accuracy of the microphone 60.

[0097] Further, please refer to Figure 1 , Figures 6-12The second sub-body 700 includes a bracket 50 and a second outer shell 400. The second sealing member 500 is sleeved on the side of the bracket 50 facing the first sub-body 600 and covers at least part of the side wall of the bracket 50. The second outer shell 400 is provided with a second receiving cavity. The inner wall of the second receiving cavity is provided with a plurality of guide ribs 420. The bracket 50 is located in the second receiving cavity, and the side wall of the bracket 50 is provided with a plurality of guide grooves 51. The guide ribs 420 are located in the guide grooves 51 one by one to guide the bracket 50 into the second receiving cavity.

[0098] In this embodiment, because the second sealing member 500 is sleeved on the side wall of the bracket 50 and the side facing the first sub-body 600, the second sealing member 500 is not easily detached from the bracket 50, and liquid can be effectively prevented from soaking into devices such as the microphone 60 located between the second sub-body 700 and the second sealing member 500, thereby improving the service life of the gas path structure. The cooperation of the guide groove 51 and the guide rib 420 enables the bracket 50 to be accurately guided into the second receiving cavity according to a preset position when the bracket 50 and the second housing 400 are connected, thereby improving the assembly efficiency of the gas path structure.

[0099] Further, please refer to Figure 9 and Figure 10 A first magnetic attractor 81 is provided on the side of the first sub-body 600 facing the second sub-body 700, and a second magnetic attractor 82 is provided on the side of the second sub-body 700 facing the first sub-body 600. The first magnetic attractor 81 and the second magnetic attractor 82 are magnetically connected.

[0100] In this embodiment, the magnetic connection between the first magnetic chuck 81 and the second magnetic chuck 82 can improve the connection stability of the first sub-body 600 and the second sub-body 700. At the same time, the first magnetic chuck 81 and the second magnetic chuck 82 can also guide the first sub-body 600 and the second sub-body 700 to complete the connection according to the preset position, thereby improving the assembly efficiency of the air passage structure.

[0101] It should be understood that at least one of the first magnetic attractor 81 and the second magnetic attractor 82 is a magnet, and the other is a magnet or metal.

[0102] Further, please refer to Figures 1-2 , Figure 5 An adjustment protrusion 120 is provided on the side of the adjustment component 100 away from the interior of the main body. The adjustment protrusion 120 is used to toggle so that the adjustment component 100 rotates.

[0103] In this embodiment, the adjustment protrusion 120 allows the user to easily rotate the adjustment component 100 around the Z-axis in the figure, thereby improving the efficiency of the air passage structure.

[0104] Further, please refer to Figures 1-2 , Figure 6Along the direction from the interior of the main body to the first air inlet 210, the second through hole includes a first sub-through hole 14 and a second sub-through hole 15 connected in sequence. The diameter of the first sub-through hole 14 is larger than that of the second sub-through hole 15. The outer wall of the adjusting component 100 is provided with a limiting protrusion 101, which abuts against the side of the second sub-through hole 15 near the interior of the main body.

[0105] In this embodiment, the first sub-through hole 14 and the second sub-through hole 15 form a stepped structure, and the limiting protrusion 101 abuts against the step of the stepped structure, thus preventing the adjustment component 100 from detaching from the main body along the Z direction in the figure, thereby improving the stability of the gas path structure.

[0106] Please refer to Figures 17-19 The gas path structure of this application also includes:

[0107] The first sub-body 600 is provided with a liquid storage chamber 93, a guide channel 94 and an injection hole 95. The guide channel 94 and the injection hole 95 are arranged opposite to each other. The guide channel 94 connects to the external environment and the liquid storage chamber 93, and the injection hole 95 connects to the external environment and the liquid storage chamber 93.

[0108] The movable component 900 is movably disposed within the guide channel 94 and is interference-fitted with the guide channel 94. It is used to reciprocate along the guide channel 94 and to block the injection hole 95 and the guide channel 94.

[0109] In this embodiment, the liquid storage chamber 93 is used to contain the aerosol generating medium. The operating principle of the gas path structure is as follows: First, in Figure 17 In the case shown, the moving component 900 blocks the injection hole 95 and the guide channel 94, so the aerosol generating medium inside the storage chamber 93 cannot flow to the outside. Even if the first sub-body 600 and the oil bottle 91 (or a device such as an injector that can transfer the aerosol generating medium into the storage chamber 93) are connected, the aerosol generating medium in the oil bottle 91 cannot enter the storage chamber 93.

[0110] Then, when the user needs to inject fluid, they can grasp the movable component 900 located outside the fluid reservoir 93, thereby driving the movable component 900 in the opposite direction along the Z-axis in the figure, so that the drive component is driven by... Figure 17 Move to the indicated position Figure 19 As shown in the diagram, at this point, the injection port 95 is connected to the external environment, and the aerosol generating medium inside the oil bottle 91 can enter the storage chamber 93. Then, when the storage chamber 93 is sufficiently filled with the aerosol generating medium, the user can drive the moving component 900 to reset to block the injection port 95, thereby ending the oil injection operation. At this time, the oil bottle 91 is still connected to the injection port 95, but the aerosol generating medium inside it can no longer enter the injection port 95.

[0111] When adding aerosol generating medium into the reservoir 93 using a syringe, the injection port 95 can be opened first, the syringe can be inserted into the injection port 95, and then the syringe can be withdrawn after the aerosol generating medium is replenished. Then the moving component 900 can be reset to block the injection port 95. At this time, the reservoir 93 is still in a sealed state.

[0112] In summary, the gas path structure of this application embodiment can move along the guide channel 94, thereby quickly blocking and opening the injection hole 95, so that the liquid storage chamber 93 can be quickly opened or sealed in the method of replenishing the aerosol generating medium through the injector; and the oil bottle 91 can also be connected to the first sub-body 600 through the injection hole 95, thereby matching the first sub-body 600 and completing the replenishment of the aerosol generating device. Therefore, the gas path structure of this application embodiment has a wide range of adaptability.

[0113] It should be understood that, such as Figure 1 and Figure 17 As shown, the liquid storage chamber 93 and the first air pipe 20 are isolated from each other. Specifically, the air outlet of the first air pipe 20 is located inside the first receiving chamber 30. Therefore, when the external oil bottle 91 adds the aerosol generating medium into the liquid storage chamber 93 through the injection hole 95, the aerosol generating medium will be blocked by the first sealing member 200 and thus cannot enter the first receiving chamber 30, so as to successfully avoid the aerosol generating medium affecting the airflow through the microphone 60.

[0114] Similarly, please refer to Figure 1 , Figures 17-22 An isolation plate 97 can also be installed inside the first sub-body 600. The isolation plate 97 is annular and surrounds the first air pipe 20. The isolation plate further divides the interior of the first sub-body 600 into an independent airflow chamber (not marked in the figure) and a liquid storage chamber 93. The first air pipe 20 is located inside the airflow chamber. The isolation between the airflow chamber and the liquid storage chamber 93 allows for... Figure 1 and Figure 21 The airflow indicated by the arrow enters the first sub-body 600 through the first air inlet 210, then directly enters the airflow chamber, and follows the direction shown by the arrow in the figure, entering the atomizing core assembly 13 from the bottom, while also causing the aerosol to flow out from the suction channel 11. After the aerosol generating medium is stored in the liquid storage chamber 93 to a certain capacity, it can directly enter the atomizing core assembly through the sixth through hole 98 provided on the side wall of the atomizing core assembly 13.

[0115] Therefore, the gas path structure in this application can effectively prevent liquid from entering the microphone 60 when the external oil bottle 91 is filled, and can also prevent the aerosol generated during the filling process from blocking the flow path of the external gas, thereby improving the service life of the gas path structure.

[0116] In some embodiments, a third liquid suction device can also be provided inside the oil bottle 91. The third liquid suction device can reduce the liquid injection speed of the oil bottle 91 to avoid the aerosol entering the liquid storage chamber 93 too quickly, which would cause the aerosol pressure at the connection between the atomizing core assembly 13 and the liquid storage chamber 93 (sixth through hole 98) to be too high, so as to avoid leakage at the connection between the atomizing core assembly 13 and the first sub-body 600.

[0117] Further, please refer to Figures 17-20 The moving component 900 includes a pull rod 910, a plug 920, and an elastic element 930 along the direction from the injection hole 95 to the guide channel 94. The guide channel 94 includes a guide groove (not marked in the figure) and a guide hole (not marked in the figure) that are interconnected. The guide hole connects the guide groove and the external environment.

[0118] The plug 920 is interference-fitted with the guide groove. One end of the pull rod 910 is connected to the plug 920, and the other end passes through the guide hole. One end of the elastic member 930 abuts against the bottom of the guide groove, and the other end abuts against the plug 920.

[0119] In this embodiment, the lever 910 can be gripped by the user to control the movement component 900. Figure 17 Move to the position shown Figure 19 The position shown; when the moving component 900 is... Figure 17 Move to the position shown Figure 19 When in the position shown, the elastic element 930 is squeezed by the blocking element 920 and the bottom of the guide groove; when the user is in Figure 19 In the case shown, after the aerosol generation medium is replenished through the injection hole 95, the pull rod 910 can be released directly. At this time, the elastic element 930 will release its stored elastic potential energy to push the blocking element 920 to reset the blocking injection hole 95.

[0120] Simultaneously, under the action of the elastic element 930, the plugging element 920 receives a continuous force moving towards the injection hole 95, thereby preventing the oil injection structure from being inverted. Figures 17-19 When the state shown is reached, the blockage 920 moves away from the injection hole 95, which causes the gas path structure to leak aerosol during shaking.

[0121] In summary, the air circuit structure of this embodiment can achieve automatic reset, thereby improving the efficiency of the air circuit structure and also improving the sealing performance of the air circuit structure.

[0122] Further, please refer to Figures 17-18The pull rod 910 includes a rod body 911 and a pull cap 912. The pull cap 912 includes a first sub-pull cap 9121 and a second sub-pull cap 9122 connected to each other. Along the direction from the pull cap 912 to the plug 920 (Z direction in the figure), the projected area of ​​the first sub-pull cap 9121 is larger than the projected area of ​​the guide hole. Part of the second sub-pull cap 9122 passes through the guide hole, and the side of the second sub-pull cap 9122 facing the rod body 911 is provided with a mounting hole (not marked in the figure). The rod body 911 passes through the mounting hole.

[0123] In this embodiment, the first sub-cap 9121 can block the guide hole. Because the projected area of ​​the first sub-cap 9121 is larger than the projected area of ​​the guide hole, the user can drive the pull rod 910 to move by grasping the second sub-cap 9122. At the same time, because the first sub-cap 9121 and the rod body 911 are connected by a mounting hole, the user can quickly switch between different sizes of caps 912 by plugging and unplugging to avoid the caps 912 becoming too large.

[0124] It should be understood that a partition plate 96 can be provided in the guide channel 94. At this time, the elastic element 930 can abut against the partition plate 96, and the rod body 911 passes through the partition plate 96 and is interference-fitted with the partition plate 96, thereby achieving the function of sealing the liquid inlet channel.

[0125] Further, please refer to Figures 17-18 One end of the blocking component 920 is interference-fitted with the guide channel 94 to block the guide channel 94.

[0126] In this embodiment, the blocking component 920 can be as follows: Figure 17 As shown, both the injection hole 95 and the guide channel 94 are blocked simultaneously, so that even after the injection hole 95 is opened, the guide channel 94 remains blocked, thereby preventing leakage from the storage chamber 93 during the replenishment of the aerosol generation medium.

[0127] Further, please refer to Figure 18 The gas path structure includes a first sealing ring, and the side wall of the plug 920 is provided with a first annular groove (not marked in the figure). The first sealing ring is located in the first annular groove and is interference-fitted with the inner wall of the first annular groove and the injection hole 95.

[0128] The gas path structure includes a second sealing ring. The side wall of the plug 920 is provided with a second annular groove (not marked in the figure). The second sealing ring is located in the second annular groove and is interference-fitted with the second annular groove and the inner wall of the guide channel 94.

[0129] In this embodiment, the first and second sealing rings are respectively interference-fitted to increase the contact area and pressure between the plug 920 and the injection hole 95 and the guide channel 94, thereby improving the sealing performance between the plug 920 and the guide channel 94 / injection hole 95. It should be understood that the first and second sealing rings can be elastic rings.

[0130] Further, please refer to Figures 20-22 The gas path structure also includes a first oil bottle 1011 and a second oil bottle 1015. The first oil bottle 1011 and the second oil bottle 1015 have different capacities. The outer wall of the first oil bottle 1011 is provided with a first threaded protrusion 1014, and the outer wall of the second oil bottle 1015 is provided with a second threaded protrusion 1016. The inner wall of the injection hole 95 is provided with a threaded groove (not marked in the figure). The first threaded protrusion 1014 and the second threaded protrusion 1016 can both be threadedly connected to the threaded groove.

[0131] In this embodiment, although the capacities of the first oil bottle 1011 and the second oil bottle 1015 differ, both the first threaded protrusion 1014 and the second threaded protrusion 1016 can be threadedly connected to the threaded groove. Therefore, both the first oil bottle 1011 and the second oil bottle 1015 can be connected to the first sub-body 600, so that the first sub-body 600 can be adapted to various models of oil bottles 91. At the same time, the threaded connection method can improve the efficiency of disassembly and installation of the oil bottle 91 and the first sub-body 600.

[0132] Further, please refer to Figures 17-22 The first oil bottle 1011 is provided with an oil cavity 1013 and a seventh through hole 1012. The seventh through hole 1012 connects the oil cavity 1013 and the liquid storage cavity 93. The plug 920 is interference-fitted with the seventh through hole 1012; and / or,

[0133] The gas path structure also includes a sealing plug 92, which is inserted into the injection hole 95 and is interference-fitted with the injection hole 95.

[0134] In this embodiment, after the first oil bottle 1011 is connected to the first sub-body 600, the injection hole 95 and the seventh through hole 1012 overlap. At this time, the plug 920 cannot directly contact the injection hole 95. Therefore, the plug 920 can be interference-fitted with the seventh through hole 1012 in the first oil bottle 1011 to block the seventh through hole 1012.

[0135] When the first sub-body 600 adds the aerosol generating medium directly into the injection hole 95 through the injector, the first sub-body 600 does not need the oil bottle 91. At this time, the sealing plug 92 can seal the injection hole 95, thereby preventing leakage of the aerosol generating medium in the injection hole 95.

[0136] It should be understood that the second oil bottle 1015 can also be provided with a seventh through hole 1012 and an oil cavity 1013, and the plug 920 is plugged in the seventh through hole 1012.

[0137] Further, please refer to Figures 12-13 The aerosol generating device also includes a PCB board 330, a button decoration 320, and a button bracket 310. The button bracket 310 abuts against the PCB board 330 and is provided with a button groove 311 and a snap-fit ​​groove 312. The button decoration 320 is located in the button groove 311. The snap-fit ​​groove 312 is provided at the connection between the bottom wall and the side wall of the button groove 311. The side wall of the button decoration 320 is provided with a snap-fit ​​321, which abuts against the snap-fit ​​groove 312.

[0138] In this embodiment, the engagement of the buckle 321 and the buckle groove 312 can prevent the button decoration 320 from falling off into the button groove 311. At the same time, the combination of the button decoration 320 and the button bracket 310 can facilitate the user to replace different button decorations 320.

[0139] Further, please refer to Figures 14-16 The aerosol generating device also includes a second housing 400, a second sub-body 700 disposed within the second housing 400, a battery 380 and a PCB board 330 disposed within the second housing 400, a positioning groove 410 disposed on the side wall of the second housing 400, a contact surface disposed at the bottom of the button bracket 310, the button bracket 310 being disposed within the positioning groove 410, and at least a portion of the button bracket 310 passing through the bottom of the positioning groove 410 and exposed to the external environment; the contact surface abuts against the side wall of the positioning groove 410.

[0140] In this embodiment, the contact surface abuts against the side wall of the positioning groove 410, thus preventing the button bracket 310 from rotating around the center of the positioning groove 410, thereby improving the structural stability of the aerosol generating device.

[0141] It should be understood that, please refer to Figure 16 The aerosol generating device may further include a charging plate 340, LEDs, a light guide column 360, a light-guiding silicone 370, and an oil bottle 91, all stacked sequentially within the second housing 400. In this case, the charging plate 340 can be connected to the PCB board 330 for charging and discharging under the control of the PCB board 330. The LED 350 can emit light of different colors or frequencies to remind the user of the current operating status of the aerosol generating device. The light guide column 360 can guide the light along a preset path for easy observation by the user. The light-guiding silicone 370 can guide the light while preventing the light guide column 360 from hitting the oil bottle 91 and also prevent external liquids from entering the LED 350. A battery 380 can be connected to the PCB board, charging plate, LEDs, and other structures to provide energy.
