Description

Technical Field

[0001] The present application relates to the technical field of aerosol generating devices, and more specifically, to an air path structure and an aerosol generating device. Background Art

[0002] Aerosol-generating devices typically have an internal air path structure, including a suction channel and a heating element. A user draws on the device, causing the aerosol-generating medium within the air path structure to contact the heating element, generating an aerosol. The aerosol then flows through the suction channel for inhalation.

[0003] Existing aerosol generating devices include oral aerosol generating devices and pulmonary aerosol generating devices. When a user inhales through the mouth, the aerosol needs to remain in the mouth for a period of time before being inhaled into the lungs. Therefore, the air path structure of the oral aerosol generating device has a small air output. When a user inhales through the lungs, the aerosol needs to enter the lungs directly. Therefore, the air path structure of the pulmonary aerosol generating device has a large air output.

[0004] The air path structure of the aerosol generating device in the prior art is fixed, and therefore it is impossible to have both mouth inhalation and lung inhalation modes at the same time, resulting in the user having to carry two aerosol generating devices at the same time, thereby reducing the efficiency of the aerosol generating device and the user experience.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0051] In this application, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of a device in actual use or operation, specifically in the drawing directions of the accompanying drawings; whereas "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "including" means "including but not limited to." Terms such as first, second, and third are used merely as designations and do not impose numerical requirements or establish a sequential order.

[0052] In this application, "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0053] In this application, "at least one" means one or more, and "plurality" 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 items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can all 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 the present application may be presented in the form of a range; it should be understood that the description in the form of a range is only for convenience and brevity and should not be construed as a hard limitation on the scope of the present application; therefore, the range description should be considered to have specifically disclosed all possible sub-ranges and single numbers within the range. For example, the description of a range from 1 to 6 should be considered to have 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., as well as single numbers within the range, such as 1, 2, 3, 4, 5 and 6, which applies regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any cited number (fractional or integer) within the indicated range.

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

[0056] The adjusting mechanism 100 is rotatably connected to the main body and is provided with a first through hole 110 . The adjusting mechanism 100 is used to rotate or translate to connect or dislocate the first through hole 110 and the first air inlet 210 to block or connect the first air inlet 210 .

[0057] In this embodiment, the adjustment mechanism 100 can control the connection or misalignment between the first through hole 110 and the first air inlet 210 by rotating or translating. Therefore, by controlling the amplitude of the adjustment mechanism 100's rotation, the conductive area of ​​the first air inlet 210 can be controlled, thereby varying the air volume output within the inhalation channel 11 during inhalation, thereby achieving the purpose of switching between mouth-to-lung inhalation and lung-to-mouth inhalation. Therefore, the air path structure of this embodiment enables users to efficiently use the aerosol generating device and provide a good user experience.

[0058] For further information, please refer to Figures 1 to 5 The main body includes a first shell 10 and a first sealing member 200. A second through hole is provided in the first shell 10. The adjustment mechanism 100 is passed through the second through hole and has an interference fit with the second through hole.

[0059] The first sealing member 200 is located within the first housing 10 and abuts against the inner wall of the first housing 10 provided with the second through hole. The first sealing member 200 is provided with a first air inlet hole 210 connected to the second through hole. Along the air inlet direction of the first air inlet hole 210, the orthographic projection area of ​​the first air inlet hole 210 is smaller than the orthographic projection area of ​​the second through hole.

[0060] When the adjustment mechanism 100 rotates, the first through hole 110 and the first air inlet hole 210 are misaligned or connected.

[0061] In this embodiment, the adjustment mechanism 100 is provided along the Z direction in the figure through the second through hole to connect itself to the first housing 10. The user can drive the adjustment mechanism 100 to rotate about the Z axis in the figure by turning the end of the adjustment mechanism 100 away from the main body. The first sealing member 200 can change the conduction area of ​​the second through hole. Because the orthographic projection area of ​​the first air inlet hole 210 is smaller than the orthographic projection area of ​​the second through hole, when the adjustment mechanism 100 component rotates and the first through hole 110 located thereon intersects with the first air inlet hole 210, external air can smoothly enter through the first air inlet hole 210. When the first through hole 110 and the first air inlet hole 210 are misaligned, the adjustment mechanism 100 will block the first air inlet hole 210, preventing air from entering the interior of the first housing 10.

[0062] Therefore, the regulating mechanism 100 , the first sealing member 200 and the first housing 10 of the air path structure of this embodiment can form a simple and easily controlled mechanical structure, thereby facilitating the user to adjust and control the air output of the air path structure.

[0063] For further information, please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7The air path 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 suction nozzle 12 and a first air pipe 20. The suction nozzle 12 is provided through the first sub-body 600 and communicates with 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 pipe 20 is connected to the microphone 60 , and the other end is connected to between the suction nozzle 12 and the atomizing core assembly 13 , so as to connect the microphone 60 and the suction channel 11 .

[0065] In this embodiment, when the user inhales, the air path structure will generate an air flow through the microphone 60, so as to trigger the atomizer core assembly 13 to work by means of the gas flow. The air intake path of the air flow is as follows: Figure 1 Indicated by the arrow.

[0066] The split design of the first sub-body 600 and the second sub-body 700 can prevent the aerosol-generating medium inside the first sub-body 600 from entering the second sub-body 700, thereby preventing the circuit components such as the microphone 60 installed in the second sub-body 700 from being soaked by the aerosol-generating medium and becoming ineffective. At the same time, the first air pipe 20 can guide the above-mentioned airflow, preventing the part of the airflow that flows through the microphone 60 and enters the first air pipe 20 from being mixed with the airflow. Figure 1 The airflows shown by the arrows converge, thus avoiding Figure 1 The airflow in the nozzle 13 and the airflow through the microphone 60 are counteracted to improve the sensitivity of the microphone 60 and the air output of the air path structure. Figure 1 When the airflow in the atomizer core assembly 13 flows, it will not contact the hot airflow in the atomizer core assembly 13, thereby preventing the hot airflow from affecting the atomizer core assembly 13. Figure 1 The airflow in the microphone is increased to improve the sensitivity of the microphone 60.

[0067] For further information, please refer to Figure 1 、 Figure 2 、 Figures 6-11 The first sub-body 600 is provided with a second air inlet 17 at one end away from the suction nozzle 12, and the second sub-body 700 is provided with a second sealing member 500. The second sealing member 500 is provided between the microphone 60 and the first sub-body 600. The second sealing member 500 is provided with an elastic ring 520 on the side 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 for connecting the first air pipe 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, thereby preventing liquid from flowing directly from the second air inlet hole 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 along the direction from the first sub-body 600 to the second sub-body 700, the second air inlet hole 17 is located inside the elastic ring 520. Therefore, when the first sub-body 600 and the second sub-body 700 are connected, the second air inlet hole 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 air path structure may further include a first liquid absorbing member (not shown), which is located between the elastic ring 520 and the first sub-body 600. In this case, the first liquid absorbing member can absorb liquid from the first sub-body 600, thereby preventing the liquid from accumulating on the surface of the second sealing member 500 and then flowing to the microphone 60.

[0070] For further information, please refer to Figures 7-11 A second air pipe 510 is provided on the second sealing member 500 , and the second air pipe 510 is provided in the second air inlet hole 17 . A fourth through hole 512 is provided on the side wall of the second air pipe 510 , and the fourth through hole 512 connects the second air pipe 510 and the first air pipe 20 .

[0071] In this embodiment, because the second air pipe 510 is connected to the first air pipe 20 via the fourth through hole 512 provided on its side wall, even if some gas refluxes in the first air pipe 20 and condenses into liquid on the top wall of the second air inlet hole 17 above the second air pipe 510, the liquid cannot enter the fourth through hole 512 when falling, thereby preventing the microphone 60 from being soaked in liquid, thereby improving the service life of the air path structure.

[0072] It should be understood that the second air pipe 510 can be a separate component. In this case, the second air pipe 510 and the second sealing member 500 are connected by assembly, so that the user can quickly replace the second air pipe 510, thereby improving the maintenance efficiency of the air path structure. The second air pipe 510 and the second sealing member 500 can also be integrally formed. In this case, the connection between the second air pipe 510 and the second sealing member 500 is more reliable and stronger.

[0073] It should be understood that the setting direction of the second air inlet 17 is the Z direction in the figure, and the setting direction of the fourth through hole 512 can be 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 toward a side away from the first air tube 20. In this case, when the aerosol or other airflow in the first air tube 20 flows into the second air tube 510, it cannot directly pass through the fourth through hole 512. Instead, it first contacts the second air inlet hole 17 and the outer wall of the second air tube 510, and then condenses to form liquid. This liquid will be retained between the second air inlet hole 17 and the second sealing member 500. Therefore, in this embodiment, the depth direction of the fourth through hole 512 is oriented toward a side away from the first air tube 20. It can effectively prevent external backflow gas from entering the second air tube 510, thereby preventing this gas or liquid from contacting the microphone 60, thereby improving the service life of the microphone 60.

[0075] For further information, please refer to Figures 1 to 6 The air path structure further includes a first sealing member 200. A partition plate 16 is provided on the inner wall of the first sub-body 600. The first sealing member 200 abuts against the partition plate 16 and the end of the atomizer core assembly 13 close to the mouthpiece 12, and forms a first accommodating cavity 30 between the first sealing member 200, the partition plate 16, and the atomizer core assembly 13. A first gap 41 is provided between the mouthpiece 12 and the atomizer core assembly 13, and the first gap 41 connects the first accommodating cavity 30 and the suction channel 11.

[0076] One end of the first air pipe 20 is passed through the first sealing member 200 and is located in the first accommodating cavity 30. The first sealing member 200 is provided with a first inclined surface 220. The first inclined surface 220 is located in the first accommodating 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 accommodating chamber 30 can prevent the aerosol medium within the first sub-body 600 from flowing back into the first air pipe 20 during shaking, thereby preventing the 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 the aerosol within the suction channel 11 partially condenses and flows back into the first gap 41 and flows along the first gap 41 into the first accommodating chamber 30, the first inclined surface 220 can prevent this portion of liquid from accumulating in the first accommodating chamber 30, while simultaneously guiding this portion of liquid back along the first inclined surface 220 to the first gap 41 and then back into the suction channel 11, thereby preventing the microphone 60 from being submerged in the liquid and reducing the loss rate of the aerosol-generating medium.

[0078] Please refer to Figures 6 to 8 In the air path structure, the third sealing member 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 accommodating groove 530 and a second air pipe 510, and the third sealing member 800 is located in the second accommodating groove 530. An accommodating cavity is defined between the third sealing member 800 and the second accommodating groove 530. Along the hole 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, first, the microphone 60 passes through the gas passage formed by the fifth through hole 810, the accommodating cavity and the second air pipe 510, so that the gas can flow along the air passage when the user inhales. Figure 1 The liquid moves in the direction of the middle arrow through the microphone 60, thereby activating the aerosol generating device containing the air path structure; secondly, the third seal 800 can effectively accommodate and limit the movement of the microphone 60, and the second seal 500 can accommodate and limit the third seal 800, so the stability of the air path structure is relatively high; then, along the Z direction in the figure, the orthographic projections of the fifth through hole 810 and the second air tube 510 are misaligned, so when the external liquid passes through the second air tube 510, it cannot drip directly into the fifth through hole 810, thereby preventing the liquid from directly passing through the fifth through hole 810 and contacting the microphone 60, thereby improving the service life of the air path structure. In summary, the air path structure of the embodiment of the present application has strong stability, long service life, and good performance.

[0081] Furthermore, if Figure 5 and Figure 6 As shown, a second gap 42 may be formed between the top of the first air pipe 20 and the inner wall of the first housing 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 accommodating chamber 30 will flow to the suction channel 11 through the first gap 41, thereby forming a negative pressure. The negative pressure will cause the gas in the first air pipe 20 to flow into the first accommodating chamber 30 through the second gap 42, and then pass 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 that of the first gap 41, even if the aerosol in the suction channel 11 enters the first accommodating chamber 30 through the first gap 41, it cannot directly enter the first air tube 20. Instead, it condenses into liquid after contacting the sidewalls of the first air tube 20 and slides down the bottom wall of the first accommodating chamber 30. In summary, the provision of the second gap 42 in this embodiment prevents external air from flowing back into the first air tube 20, thereby preventing the microphone 60 from being corroded by liquid, thereby improving the sensitivity of the microphone 60.

[0084] Secondly, the second gap 42 enables the gas in the first air tube 20 to flow accordingly with the user's inhalation, thereby promoting the gas to flow through the microphone 60 and improving the detection accuracy of the microphone 60; at the same time, because the second gap 42 is located at the top of the first accommodating cavity 30, the gas in the first air tube 20 will compress the first accommodating cavity 30 to a certain extent after passing through the second gap 42, and then the liquid at the bottom of the first accommodating cavity 30 (part of the aerosol is condensed) will flow toward 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 (Z-axis direction) can be set to be smaller than the width of the first gap 41. At this time, it can further prevent the gas entering the first accommodating cavity 30 from the first gap 41 from flowing back into the first air pipe 20 to prevent the microphone from being corroded by liquid.

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

[0087] In this embodiment, the opening allows the airflow flowing through the microphone 60 and into the first air pipe 20 to pass through, thereby allowing the airflow to enter the first accommodating cavity 30 from the first air pipe 20 and then enter the suction channel 11 from the first accommodating cavity 30 through the first gap 41.

[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 accommodating chamber 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 housing 10, forming a liquid such as an aerosol-generating medium. This liquid then flows under the action of gravity along the side wall of the first air tube 20 or the inner wall of the first housing 10 to the bottom wall of the first accommodating chamber 30. Therefore, the first air tube 20 abuts the inner wall of the first housing 10, and the technical solution of providing an opening can prevent liquid from entering the microphone. At the same time, because the first air tube 20 abuts the inner wall of the first housing 10, the first housing 10 can prevent the first air tube 20 from shaking through friction, thereby improving the stability of the air path structure and thereby increasing the service life of the aerosol generating device.

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

[0090] For further information, please refer to Figures 6 to 8 The third sealing member 800 is provided with a second inclined surface 830. Along the depth direction of the fifth through hole 810 (the Z direction in the figure), the orthographic projection of the second air pipe 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 (the X direction in the figure), the vertical distance between the second inclined surface 830 and the second air pipe 510 gradually increases.

[0091] In this embodiment, along the Z direction in the figure, the orthographic projection of the second air pipe 510 is located on the second inclined surface 830. Therefore, when liquid flows from the second air pipe 510 into the accommodating chamber, the liquid will move along the inclined direction of the second inclined surface 830. In the direction away from the fifth through hole 810, the vertical distance between the second inclined surface 830 and the second air pipe 510 gradually increases. Therefore, when the liquid lands on the second inclined surface 830, it will move in a direction away from the fifth through hole 810, thereby effectively preventing the 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] For further information, please refer to Figure 7 The air path structure further includes a second liquid absorbing member 70 , and the third sealing member 800 is further provided with a third accommodating groove 840 , the notch of the third accommodating groove 840 is connected to an end of the second inclined surface 830 away from the fifth through hole 810 .

[0093] In this embodiment, the notch 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 absorbent member 70 in the third receiving groove 840. The second liquid absorbent member 70 then stores and absorbs the liquid, preventing the liquid from flowing back to the microphone 60 when the user shakes the air path structure (such as when the user shakes the aerosol generating device).

[0094] It should be understood that the second liquid-absorbing member 70 may be oil-absorbing cotton.

[0095] For further information, 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 arranged at the bottom of the second sub-receiving groove 820. The fifth through hole 810 is connected to the first sub-receiving groove. The microphone 60 is located in the second sub-receiving groove 820 and is interference fit 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 in position during operation, and the first sub-receiving groove can ensure that the gas still has a larger flow channel after passing through the fifth through hole 810, thereby allowing the microphone 60 to contact a larger volume of gas, thereby improving the accuracy of the microphone 60.

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

[0098] In this embodiment, because the second seal 500 is mounted on the sidewall of the bracket 50 and on the surface facing the first sub-body 600, the second seal 500 is not easily removed from the bracket 50. Furthermore, liquid can be effectively prevented from soaking into components such as the microphone 60 located between the second sub-body 700 and the second seal 500, thereby improving the service life of the air path structure. The cooperation between the guide groove 51 and the guide rib 420 ensures that when the bracket 50 and the second housing 400 are connected, the bracket 50 is precisely guided into the second accommodating cavity according to the preset position, thereby improving the assembly efficiency of the air path structure.

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

[0100] In this embodiment, the magnetic connection between the first magnetic component 81 and the second magnetic component 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 component 81 and the second magnetic component 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 path structure.

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

[0102] For further information, please refer to Figures 1-2 、 Figure 5An adjusting protrusion 120 is provided on one side of the adjusting mechanism 100 away from the interior of the main body, and the adjusting protrusion 120 is used to turn to rotate the adjusting mechanism 100.

[0103] In this embodiment, the adjusting protrusion 120 can facilitate the user to turn the adjusting mechanism 100 around the Z axis in the figure, so as to improve the use efficiency of the air path structure.

[0104] For further information, please refer to Figures 1-2 、 Figure 6 , along the direction from the inside of the main body to the first air inlet hole 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 the second sub-through hole 15, and the outer wall of the adjustment mechanism 100 is provided with a limiting protrusion 101, which abuts against the side of the second sub-through hole 15 close to the inside of the main body.

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

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

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

[0108] The moving component 900 is movably disposed in the guide channel 94 and has an interference fit with the guide channel 94 , and is used to move back and forth along the guide channel 94 and 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 principle of the air path structure is as follows: First, Figure 17 In the case shown, the movable component 900 blocks the injection hole 95 and the guide channel 94, so that the aerosol generating medium inside the liquid 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 liquid storage chamber 93) are connected, the aerosol generating medium in the oil bottle 91 cannot enter the liquid storage chamber 93.

[0110] Then, when the user needs to inject liquid, he can grasp the moving component 900 outside the liquid storage chamber 93, and then drive the moving component 900 in the reverse direction of the Z axis in the figure, so that the driving component is Figure 17Move to the position shown Figure 19 At this point, the injection hole 95 is connected to the external environment, and the aerosol-generating medium in the oil bottle 91 can enter the liquid storage chamber 93. Then, when the aerosol-generating medium in the liquid storage chamber 93 is sufficiently filled, the user can drive the movable assembly 900 back to block the injection hole 95, thereby ending the oil injection operation. At this point, the oil bottle 91 is still connected to the injection hole 95, but the aerosol-generating medium inside it can no longer enter the injection hole 95.

[0111] When using a syringe to add an aerosol-generating medium into the liquid storage chamber 93, the liquid injection hole 95 can be opened first, and the syringe can be inserted into the liquid injection hole 95. Then, after the aerosol-generating medium is replenished, the syringe can be withdrawn, and then the movable component 900 can be reset to block the liquid injection hole 95. At this time, the liquid storage chamber 93 is still in a sealed state.

[0112] In summary, the air path structure of the embodiment of the present application can move along the guide channel 94, and then quickly block and open the injection hole 95, so that when the aerosol generating medium is replenished by the injector, the liquid storage chamber 93 can be quickly opened or sealed; and the oil bottle 91 can also be connected to the first sub-body 600 through the injection hole 95, and then match the first sub-body 600 to complete the replenishment of the aerosol generating device, so the air path structure of the embodiment of the present application has a wide range of adaptability.

[0113] It should be understood that if 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 end of the first air pipe 20 is located in the first accommodating chamber 30. Therefore, when the external oil bottle 91 adds the aerosol generating medium into the liquid storage chamber 93 through the liquid injection hole 95, the aerosol generating medium will be blocked by the first sealing member 200 and cannot enter the first accommodating chamber 30, thereby successfully preventing the aerosol generating medium from affecting the airflow flowing through the microphone 60.

[0114] For further information, please refer to Figures 1 to 5 and Figure 17 The main body (first sub-body 600) is provided with a liquid storage cavity 93, a guide channel 94 and a liquid injection hole 95. The guide channel 94 and the liquid injection hole 95 are arranged opposite to each other. The guide channel 94 connects the second through hole and the liquid storage cavity 93, and the liquid injection hole 95 connects the external environment and the liquid storage cavity 93.

[0115] The adjusting mechanism 100 includes a moving component 900 and a rotating component 130. The moving component 900 is inserted into the rotating component 130 and has an interference fit with the guide channel 94. It is used to move back and forth along the guide channel 94 and block the injection hole 95 and the guide channel 94. The rotating component 130 is rotatably connected to the second through hole and seals the second through hole together with the moving component 900. A first through hole 110 is also provided.

[0116] In this embodiment, first, the movable assembly 900 and the rotating assembly 130 jointly form the regulating mechanism 100. Thus, the regulating mechanism 100 can regulate both the flow of aerosol-generating medium into the air path structure and the airflow during the user's inhalation, thereby switching between various inhalation modes, such as lung inhalation and mouth inhalation. Secondly, because the movable assembly 900 and the rotating assembly 130 jointly seal the second through-hole (the first sub-through-hole 14 and the second sub-through-hole 15), and the guide channel 94 communicates with the second through-hole, after the rotating assembly 130 is restrained by the second through-hole, it can prevent the portion of the movable assembly 900 (the blocking member 920) moving within the guide channel 94 from disengaging from the first sub-body 600 in a direction away from the liquid injection hole 95, thereby preventing the movable assembly 900 from disengaging during movement. Finally, because the movable assembly 900 is interposed within the rotating assembly 130, the rotating assembly 130 can rotate about the central axis of the movable assembly 900 during rotation. At this time, the movable assembly 900 provides support and positioning, preventing the rotating assembly 130 from shifting during rotation.

[0117] In summary, compared to adding other mechanical structures, respectively limiting the travel of the movable assembly 900 and supporting the fixed-axis rotation of the rotating assembly 130, the movable assembly 900 and the rotating assembly 130 of this embodiment together form the adjustment mechanism 100, and the two mutually restrict and support each other, which can save internal space of the gas path structure and omit additional mechanical structures, thereby reducing the production cost and production efficiency of the gas path structure.

[0118] It should be understood that when the adjustment mechanism includes a moving component 900 and a rotating component 130, the adjustment protrusion 110 and the limiting protrusion 101 are both arranged on the rotating component, that is, the rotating component 130 and the first sub-through hole 14 and the second sub-through hole 15 are limited by the limiting protrusion 101 to prevent the rotating component 130 from detaching from the first sub-body 600 in a direction away from the injection hole 95. The user can move the rotating component 130 around the moving component by turning the adjustment protrusion 101.

[0119] Similarly, please refer to Figure 1 、 Figures 17 to 22 , an isolation plate 97 can also be set in the first sub-body 600. The isolation plate 97 is annular and is set around the first air pipe 20. The isolation plate further divides the interior of the first sub-body 600 into an independent air flow chamber (not marked in the figure) and a liquid storage chamber 93, wherein the first air pipe 20 is located in the air flow chamber. The isolation of the air flow chamber and the liquid storage chamber 93 can make Figure 1 and Figure 21The airflow indicated by the arrow enters the first sub-body 600 through the first air inlet 210, then directly enters the airflow chamber and flows into the atomizer core assembly 13 from the bottom thereof in the direction indicated by the arrow in the figure, driving the aerosol out of 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 atomizer core assembly through the sixth through hole 98 provided in the side wall of the atomizer core assembly 13.

[0120] Therefore, the air path structure in the present application can effectively prevent the external oil bottle 91 from causing liquid to enter the microphone 60 during liquid injection, and can also prevent the aerosol-generating medium from blocking the flow path of the external gas during liquid injection, thereby improving the service life of the air path structure.

[0121] In some embodiments, a third liquid absorption component can be further provided in the oil bottle 91, and the third liquid absorption component can reduce the injection speed of the oil bottle 91 to prevent the aerosol from entering the liquid storage chamber 93 too quickly, thereby causing the aerosol hydraulic pressure at the connection between the atomizer core assembly 13 and the liquid storage chamber 93 (the sixth through hole 98) to be too high, so as to prevent leakage at the connection between the atomizer core assembly 13 and the first sub-body 600.

[0122] For further information, please refer to Figures 17-20 The moving assembly 900 includes a pull rod 910, a blocking member 920, and an elastic member 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.

[0123] The blocking piece 920 is interference fit in the guide groove. One end of the pull rod 910 is connected to the blocking piece 920 and the other end is passed through the guide hole. One end of the elastic piece 930 abuts against the bottom of the guide groove and the other end abuts against the blocking piece 920.

[0124] In this embodiment, the pull rod 910 can be grasped by the user to control the movement of the moving assembly 900. Figure 17 Move the position shown to Figure 19 The position shown; when the moving assembly 900 is Figure 17 Move the position shown to Figure 19 In the position shown, the elastic member 930 is squeezed by the blocking member 920 and the bottom of the guide groove; Figure 19 In the case shown, after the aerosol generating medium is replenished through the injection hole 95, the pull rod 910 can be directly released. At this time, the elastic member 930 will release its stored elastic potential energy to push the blocking member 920 to return to its original position and block the injection hole 95.

[0125] At the same time, under the action of the elastic member 930, the blocking member 920 obtains the force to continuously move toward the injection hole 95, thereby preventing the oil injection structure from being inverted ( Figures 17-19In the state shown in FIG, the blocking member 920 moves to a position away from the liquid injection hole 95, thereby causing the aerosol generating medium to leak during the shaking of the air path structure.

[0126] In summary, the air path structure of this embodiment can achieve automatic reset, thereby improving the use efficiency of the air path structure and also improving the sealing performance of the air path structure.

[0127] For further information, please refer to Figures 17-18 The 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 that are connected to each other. Along the direction from the pull cap 912 to the blocking member 920 (Z direction in the figure), the orthographic projection area of ​​the first sub-pull cap 9121 is larger than the orthographic projection area of ​​the guide hole. Part of the second sub-pull cap 9122 is inserted into the guide hole, and a mounting hole (not marked in the figure) is provided on the side of the second sub-pull cap 9122 facing the rod body 911, and the rod body 911 is inserted into the mounting hole.

[0128] In this embodiment, the first sub-pull cap 9121 serves to block the guide hole. Because the orthographic projection area of ​​the first sub-pull cap 9121 is larger than the orthographic projection area of ​​the guide hole, the user can drive the pull rod 910 by grasping the second sub-pull cap 9122. Furthermore, because the first sub-pull cap 9121 is connected to the rod 911 via the mounting hole, the user can quickly switch between pull caps 912 of different sizes by simply plugging and unplugging, thereby preventing the pull cap 912 from becoming too bulky.

[0129] It should be understood that a partition plate 96 may be provided in the guide channel 94 , and the elastic member 930 may abut against the partition plate 96 , and the rod body 911 may pass through the partition plate 96 and have an interference fit with the partition plate 96 , thereby achieving the effect of sealing the liquid inlet channel.

[0130] For further information, please refer to Figures 17-18 One end of the blocking member 920 is interference fit with the guide channel 94 to block the guide channel 94.

[0131] In this embodiment, the blocking member 920 can be as follows Figure 17 As shown, the injection hole 95 and the guide channel 94 are blocked at the same time, so that after the injection hole 95 is opened, the guide channel 94 is still blocked, thereby preventing the liquid storage chamber 93 from leaking during the process of replenishing the aerosol generating medium.

[0132] For further information, please refer to Figure 18 The gas path structure includes a first sealing ring. The side wall of the blocking member 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 has an interference fit with the first annular groove and the inner wall of the liquid injection hole 95.

[0133] The air path structure includes a second sealing ring. The side wall of the blocking member 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 has an interference fit with the second annular groove and the inner wall of the guide channel 94.

[0134] In this embodiment, the first sealing ring and the second sealing ring can respectively form an interference fit to increase the contact area and pressure between the plugging member 920 and the liquid injection hole 95 and the guide channel 94, thereby improving the sealing between the plugging member 920 and the guide channel 94 / liquid injection hole 95. It should be understood that the first sealing ring and the second sealing ring can be elastic rings.

[0135] For further information, please refer to Figures 20 to 22 The air path structure also includes a first oil bottle 1011 and a second oil bottle 1015. The capacities of the first oil bottle 1011 and the second oil bottle 1015 are different. 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), and the first threaded protrusion 1014 and the second threaded protrusion 1016 can both be threadedly connected to the threaded groove.

[0136] In this embodiment, although there is a difference in the capacity of the first oil bottle 1011 and the second oil bottle 1015, since the first threaded protrusion 1014 and the second threaded protrusion 1016 can both be threadedly connected to the thread groove, the first oil bottle 1011 and the second oil bottle 1015 can both be connected to the first sub-body 600, so that the first sub-body 600 can adapt to various models of oil bottles 91; at the same time, the threaded connection method can improve the disassembly and installation efficiency of the oil bottle 91 and the first sub-body 600.

[0137] For further information, please refer to Figures 17 to 22 The first oil bottle 1011 is provided with an oil chamber 1013 and a seventh through hole 1012 , the seventh through hole 1012 is connected with the oil chamber 1013 and the liquid storage chamber 93 , and the blocking member 920 is interference-fitted with the seventh through hole 1012 ; and / or

[0138] The gas path structure further includes a sealing plug 92 , which is inserted into the liquid injection hole 95 and has an interference fit with the liquid injection hole 95 .

[0139] In this embodiment, when the first oil bottle 1011 is connected to the first sub-body 600, the liquid injection hole 95 and the seventh through hole 1012 overlap. At this time, the blocking member 920 cannot directly contact the liquid injection hole 95; therefore, the blocking member 920 can be interference fit with the seventh through hole 1012 in the first oil bottle 1011 to block the seventh through hole 1012.

[0140] When the first sub-body 600 directly adds the aerosol-generating medium into the injection hole 95 through the injector, the first sub-body 600 does not need the oil bottle 91. In this case, the sealing plug 92 can seal the injection hole 95, thereby preventing the aerosol-generating medium in the injection hole 95 from leaking.

[0141] It should be understood that the second oil bottle 1015 can also be provided with a seventh through hole 1012 and an oil chamber 1013 , and the blocking member 920 blocks the seventh through hole 1012 .

[0142] For further information, please refer to Figures 12 and 13 The aerosol generating device also includes a PCB board 330, a key decoration 320 and a key bracket 310. The key bracket 310 is abutted against the PCB board 330 and is provided with a key slot 311 and a buckle slot 312. The key decoration 320 is located in the key slot 311; the buckle slot 312 is provided at the connection between the bottom wall and the side wall of the key slot 311, and the side wall of the key decoration 320 is provided with a buckle 321, which abuts against the buckle slot 312.

[0143] In this embodiment, the cooperation between the buckle 321 and the buckle groove 312 can prevent the key decoration 320 from falling off the key groove 311 . At the same time, the combination of the key decoration 320 and the key bracket 310 can facilitate users to replace different key decorations 320 .

[0144] For further information, please refer to Figures 14 to 16 The aerosol generating device also includes a second shell 400, the second sub-body 700 is arranged in the second shell 400, the battery 380 and the PCB board 330 are arranged in the second shell 400, the side wall of the second shell 400 is provided with a positioning groove 410, and the bottom of the key bracket 310 is provided with an abutment surface. The key bracket 310 is arranged in the positioning groove 410, and at least part of the key bracket 310 is passed through the bottom of the positioning groove 410 and exposed to the external environment; the abutment surface abuts against the side wall of the positioning groove 410.

[0145] In this embodiment, the abutting surface abuts against the side wall of the positioning groove 410 , thereby 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.
