[0033] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple", "several" is two or more, unless otherwise explicitly specified.

[0034] It should be understood that the structures, proportions, sizes and the like shown in the drawings of the present application are only used to cooperate with the content disclosed in the description, to be understood and read by those skilled in the art, and do not have technical significance, and any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0035] As shown in the drawings, the aerosol generating device provided by the embodiments of the present application is provided with a heating cavity 2 and an air flow channel 3 in the device body 1, and the shell wall of the device body 1 is provided with a cigarette inlet 4 and an air inlet 5,

[0036] One end of the heating cavity 2 is communicated with the cigarette inlet 4, and the other end is communicated with the air flow channel 3, and the end of the air flow channel 3 away from the heating cavity 2 is communicated with the air inlet 5;

[0037] A ball 6 is arranged in the air flow channel 3, the outer diameter of the ball 6 is smaller than the inner diameter of the air flow channel 3, and the gravity of the ball 6 is smaller than the reaction force of the airflow in the air flow channel 3;

[0038] Limiting structures 7 are arranged between the air flow channel 3, the air inlet 5 and the heating cavity 2.

[0039] The present application provides an aerosol generating device, in which a heating chamber 2 and an air flow channel 3 are provided in a device body 1, and a cigarette inlet 4 and an air inlet 5 are provided on the shell wall of the device body 1. One end of the heating chamber 2 is connected to the cigarette inlet 4, and the other end is connected to the air flow channel 3. The end of the air flow channel 3 away from the heating chamber 2 is connected to the air inlet 5; a sphere 6 is provided in the air flow channel 3, the outer diameter of the sphere 6 is smaller than the inner diameter of the air flow channel 3, and the gravity of the sphere 6 is smaller than the reaction force of the airflow in the air flow channel 3 on it; a limiting structure 7 is provided between the air flow channel 3 and the air inlet 5 and the heating chamber 2. The aerosol generating device provided by this application has a sphere 6 disposed within the air flow channel 3. Since the gravity of the sphere 6 is less than the reaction force of the airflow within the air flow channel 3, the airflow generated when the consumer inhales will drive the sphere 6 to move within the air flow channel 3 and collide with the inner wall of the air flow channel 3, making a sound. The sound changes prompt the user whether the frequency and depth of inhalation are appropriate. If the sound is rapid, it can prompt the user to slow down the frequency and depth of inhalation, improving the user experience. For other people nearby, the sound of the sphere 6 can also remind them that someone is using the aerosol generating device and they can avoid it in time. In areas where smoking is not allowed, the sound of the sphere 6 will also reduce the probability of the user taking out the aerosol generating device. In addition, the sound produced by the collision of the sphere 6 also improves the playability of the aerosol generating device.

[0040] The air flow in the air flow channel 3 is generated by active inhalation by the consumer, and the gravity of the sphere 6 only needs to be smaller than the minimum force that the consumer can use to draw the aerosol.

[0041] Preferably, the interior of the sphere 6 is hollow, and the wall of the sphere 6 has a plurality of through holes for airflow to pass through.

[0042] Preferably, the interior of the sphere 6 is hollow, and the wall of the sphere 6 has multiple through holes for airflow to pass through. This not only reduces the material usage of the sphere 6 and thus reduces its weight, making it easier to be driven by the airflow; moreover, the hollow structure of the sphere 6 and the through holes allow airflow to pass through, which can reduce the resistance of the sphere 6 to the airflow, so that when consumers use the aerosol generating device provided by this application, the change in suction force is small and the adaptation period is short compared to using other devices.

[0043] Preferably, the ball 6 is made of metal or hard plastic.

[0044] Depending on the material, the sound level of the ball 6 colliding with the inner wall of the air flow channel 3 varies. Preferably, the ball 6 is made of metal (such as iron, copper, etc.) or hard plastic (such as polyethylene, polypropylene, etc.), which makes the collision easier to produce sound and the sound is crisp.

[0045] Preferably, a plurality of spheres 6 are provided in the air flow channel 3 .

[0046] One sphere 6 or multiple (two or more) spheres 6 may be provided in the air flow channel 3 , which may collide not only with the inner wall of the air flow channel 3 but also with each other.

[0047] Preferably, the limiting structure 7 is a perforated plate 71 fixedly connected to the inner wall of the air flow channel 3, and the diameter of the hole in the perforated plate 71 is smaller than the outer diameter of the sphere 6; or,

[0048] The limiting structure 7 is a flange 72 fixedly connected to the inner wall of the air flow channel 3, and the inner diameter of the flange is smaller than the outer diameter of the sphere 6; or,

[0049] The limiting structure 7 is a limiting ring 73 fixedly connected to the inner wall of the air flow channel 3 via a support rod 731 . The inner diameter of the limiting ring 73 and the length of the support rod 731 are both smaller than the outer diameter of the sphere 6 .

[0050] In the present application, the sphere 6 is restricted by the limiting structure 7 provided between the air flow channel 3 and the air inlet 5 and the heating chamber 2. It can only move within the air flow channel 3 and will not fall out or enter the heating chamber 2 to affect the insertion and suction of the aerosol generating product.

[0051] Specifically, the limiting structure 7 can be any one of the implementation modes such as a perforated plate 71 , a flange 72 , a limiting ring 73 and a support rod 731 .

[0052] When using the orifice plate 71 structure, the orifice plate 71 is fixedly connected to the inner wall of the air flow channel 3. The diameter of the hole in the orifice plate 71 is smaller than the outer diameter of the sphere 6, so the sphere 6 will not fall out. At the same time, air can pass through the hole without affecting the suction. The shape of the hole in the orifice plate 71 can be any shape, such as rectangular, circular, elongated, etc.

[0053] When the flange 72 structure is used, the flange 72 is fixedly connected to the inner wall of the air flow channel 3 and protrudes into the air flow channel 3. The inner diameter of the flange 72 (i.e., the diameter of the flange 72 closest to the central axis of the air flow channel 3) constitutes a restriction on the position of the sphere 6. By setting the inner diameter of the flange 72 to be smaller than the outer diameter of the sphere 6, the sphere 6 will not fall out. At the same time, air can pass through the hole in the middle of the flange 72 and can be sucked smoothly.

[0054] When the retaining ring 73 and the support rod 731 are used in conjunction, the support rod 731 extends radially along the air flow channel 3, with one end connected to the inner wall of the air flow channel 3 and the other end connected to the outer wall of the retaining ring 73. The inner diameter of the retaining ring 73 (i.e., the distance between the inner wall of the retaining ring 73 and the central axis of the air flow channel 3) is smaller than the outer diameter of the sphere 6, preventing the sphere 6 from falling out of the center of the retaining ring 73. Furthermore, the length of the support rod 731 is also smaller than the outer diameter of the sphere 6, preventing the sphere 6 from falling out of the gap between the inner wall of the air flow channel 3 and the outer wall of the retaining ring 73. At the same time, air can pass through the gap on both sides of the retaining ring 73.

[0055] The limiting structure 7 between the air flow channel 3 and the air inlet 5 and the limiting structure 7 between the air flow channel 3 and the heating cavity 2 can be the same or different. For example, both limiting structures 7 use the structure of the hole plate 71, or one uses the hole plate 71 and the other uses the flange 72.

[0056] Preferably, the air inlet 5 is also provided with a fan 8, and the fan 8 is located on the side of the limiting structure 7 close to the outer wall of the device body 1.

[0057] More preferably, the air inlet 5 is also provided with a fan 8, and the fan 8 is located on the side of the limiting structure 7 close to the outer wall of the device body 1, so that the movement of the ball 6 is limited by the limiting structure 7 and does not collide with the fan 8. The fan 8 rotates during suction, making the air flow into the cigarette more stable and gentle. In addition, it can also enhance the visual effect of suction and improve the playing nature.

[0058] The fan 8 can be fixed on the inner wall of the air flow channel 3 by a support.

[0059] Preferably, the shell wall of the device body 1 is at least partially transparent, and the transparent shell wall corresponds to the position of the air flow channel 3.

[0060] Preferably, the shell wall of the device body 1 is at least partially transparent, and the transparent shell wall corresponds to the position of the air flow channel 3. When the consumer sucks, he can not only hear the sound, but also see the movement of the ball 6, which provides a multi-dimensional sensory experience, a visual and auditory suction process, enhances the playing nature, and improves the consumer experience.

[0061] The shell wall of the device body 1 is at least partially transparent, which can be the transparent shell wall corresponding to part of the position of the air flow channel 3, so that the ball 6 moves between the transparent and opaque shell walls, providing a visual experience that is visible and invisible. Alternatively, the shell wall of the device body 1 can be transparent, and the consumer can observe the movement of the ball 6 throughout the process. In addition, the transparent part of the shell wall can be larger than the corresponding part of the air flow channel 3, which can display other structures in the aerosol generating device or cooperate with the design to display product LOGO and other content.

[0062] Preferably, the surface of the ball 6 has a color layer or a fluorescent layer.

[0063] Preferably, the surface of the ball 6 has a color layer. The color layer can be yellow, green, white, or various colors, providing a more rich visual experience.

[0064] The surface of the ball 6 can also be provided with a fluorescent layer. The light-induced energy storage fluorescent material stores light energy after being irradiated by natural light, fluorescent light, ultraviolet light, etc. After stopping the light irradiation, it is slowly released in the form of fluorescent light. Therefore, in the night or dark place, the light-emitting ball 6 can still be observed to move for several hours to several dozen hours. Therefore, the light-emitting ball 6 can be observed to move when sucking in the night or dark place.

[0065] Preferably, the central axes of the heating chamber 2 and the air flow channel 3 coincide with each other.

[0066] Preferably, the central axes of the heating chamber 2 and the air flow channel 3 coincide with each other, so that there is no angle between the heating chamber 2 and the air flow channel 3, and the air flow is smoother.

[0067] The heating chamber 2 and the air flow channel 3 can be set to be perpendicular to the end face of the device body 1, so that the heating chamber 2 and the air flow channel 3 pass through the two end faces of the device body 1, and the cigarette inlet 4 and the air inlet 5 are respectively located on different end faces.

[0068] Preferably, the device body 1 further includes a power supply 9, a controller 10 and a heating component 11.

[0069] The heating component 11 is disposed on the periphery of the heating chamber 2 , and the power supply 9 , the controller 10 and the heating component 11 are electrically connected.

[0070] The preferred device body 1 also includes a power supply 9, a controller 10 and a heating component 11. The heating component 11 is arranged on the periphery of the heating chamber 2, and the power supply 9, the controller 10 and the heating component 11 are electrically connected. The power supply 9 supplies power to the controller 10, and the controller 10 controls the heating component 11 to work, so that the heating chamber 2 accumulates heat. The aerosol-generating product inserted into the heating chamber 2 releases aerosol when heated. The heating chamber 2 is connected to the air flow channel 3. When the consumer inhales, the air enters the heating chamber 2 from the air flow channel 3, so that the consumer can inhale smoothly.

[0071] When the heating chamber 2 and the air flow channel 3 are arranged to pass through the two end surfaces of the device body 1, the power supply 9 and the controller 10 can be arranged on the side.

[0072] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
