Description

Technical Field

[0001] This utility model relates to the field of non-combustible cigarette technology, specifically to an aerosol generating device. Background Technology

[0002] In heated tobacco products, heating air and then using that heated air to further heat the cigarette offers advantages such as gentle and uniform heating. However, due to air's low specific heat capacity and slow thermal conductivity, current methods using airflow heating often suffer from high heating element temperatures and high energy consumption. Furthermore, in existing products, the heat carried by the cigarette is primarily provided by the small amount (e.g., 55ml) of air inhaled during the user's inhalation (which lasts approximately 2 seconds). This portion of heat is actually minimal. The majority of the cigarette's heat comes from conduction between inhalations, transferring heat to components in direct or indirect contact with the cigarette. Since the cigarette's heat originates from conduction rather than the convective heat transfer that airflow heating aims to achieve, it fails to realize the advantages of airflow heating. Utility Model Content

[0003] This invention proposes an aerosol generating device to solve the above-mentioned problems.

[0004] In a first aspect, embodiments of this utility model disclose an aerosol generating device, comprising:

[0008] The path adjustment mechanism is located in the isolation space. The path adjustment mechanism is used to adjust the air flow path applied by the flow rate adjustment mechanism and / or to adjust the flow path of the condensate after aerosol condensation and can retain the condensate.

[0009] By adopting the above technical solution, the aerosol generating device of this utility model improves the temperature of the environment where the flow rate regulating mechanism is located by setting up an isolation space to separate the flow rate regulating mechanism from the heating component, which is beneficial to extending the service life of the flow rate regulating mechanism. Furthermore, the isolation space, as a buffer zone, provides a collection space for condensate, which helps to mitigate damage to the flow rate regulating mechanism from condensate. Further, by setting up a path regulating mechanism within the isolation space to adjust the airflow path, the potentially turbulent flow generated during user inhalation can be streamlined into a uniform and stable laminar flow, improving the heating uniformity of the aerosol-generated product and enhancing the consistency of the aerosol's taste. By setting up a path regulating mechanism within the isolation space to adjust the flow path of the condensate, and because the path regulating mechanism can be used to collect aerosol condensate, the flow rate regulating mechanism can be protected from contamination, ensuring its long-term accuracy and reliability.

Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0059] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0060] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0061] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0062] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0063] Firstly, reference Figure 1 , Figure 2 and Figure 3 This utility model provides an aerosol generating device, comprising: a housing 2, the housing 2 having an internal cavity 3, a heating component 4, a flow rate regulating mechanism 5 (such as a fan), an isolation space 6, and a path regulating mechanism 7; the cavity 3 is used to contain aerosol generating products, such as cigarettes, and extends along its axial direction; the cavity 3, the heating component 4, the isolation space 6, and the flow rate regulating mechanism 5 are sequentially distributed along the axial direction; the heating component 4 is used to heat the aerosol generating products contained in the cavity 3 by heating a medium to generate aerosol; the flow rate regulating mechanism 5 is used to regulate the flow rate of the medium heated by the heating component 4; the isolation space 6 separates the heating component 4 and the flow rate regulating mechanism 5, and the isolation space 6 connects the space where the heating component 4 is located and the space where the flow rate regulating mechanism 5 is located; the path regulating mechanism 7 is disposed in the isolation space 6, and the path regulating mechanism 7 is used to regulate the air flow path applied by the flow rate regulating mechanism 5 and / or to regulate the flow path of the condensate after aerosol condensation and to allow the condensate to remain.

[0064] By adopting the above technical solution, the aerosol generating device provided in this embodiment of the utility model can improve the temperature of the environment where the flow rate regulating mechanism 5 is located by setting an isolation space 6 to separate the flow rate regulating mechanism 5 from the heating component 4, which is beneficial to improving the service life of the flow rate regulating mechanism 5. Moreover, the isolation space 6, as a buffer, provides a space for the condensate to collect, which helps to alleviate or avoid damage to the flow rate regulating mechanism 5 by aerosol condensate. Furthermore, compared with setting a cavity only between the heating component 4 and the flow rate regulating mechanism 5, although the airflow resistance is small, the airflow will concentrate and rapidly impact the heating component 4 from the center of the heating component 4 or the path of least resistance, resulting in uneven heat exchange and short heat exchange time. In addition, the airflow direction is uncontrolled and cannot guide the hot airflow to the area that needs more heat. By setting a path regulating mechanism 7 in the isolation space 6 to regulate the airflow path, the potentially turbulent airflow generated when the user inhales is sorted into a uniform and stable airflow (such as a rotating airflow), improving the heating uniformity of the aerosol generated product and improving the consistency of the aerosol taste. By setting a path adjustment mechanism 7 within the isolation space 6 to regulate the flow path of the condensate (e.g., adjusting the straight flow path of the condensate along the inner wall of the isolation space 6 to a curved path), and by using the path adjustment mechanism to collect aerosol condensate, the flow rate adjustment mechanism 5 is protected from contamination, ensuring its long-term accuracy and reliability. In this embodiment, the path adjustment mechanism 7 transforms the isolation space 6 from a simple "cavity" into a functional structural component, helping to strengthen the internal structure, optimize the spatial layout of the aerosol generating device, improve uneven heating and low heat exchange efficiency, and ultimately enhance the flavor and energy efficiency of the smoking device.

[0065] In this embodiment of the invention, the aerosol generating device further includes a vacuum structure 1 located inside the housing 2. The accommodating cavity 3 and the heating element 4 are located within the vacuum structure 1. The vacuum structure 1 can isolate the heat transfer of the heating element 4, preventing the outer surface temperature of the aerosol generating device from becoming too high and improving the user experience. The heating element 4 can be a heating wire, a heating element with slurry attached to a ceramic substrate, or a heating element based on electromagnetic principles; this embodiment does not impose any limitations on this. The isolation space 6 is the empty space between the heating element 4 and the flow rate regulating mechanism 5. Specifically, the isolation space 6 is formed inside the housing 2.

[0066] In this embodiment of the present invention, the path adjustment mechanism 7 includes: a cylinder 71 and a collection unit. The cylinder 71 has a channel that extends through both ends. Preferably, the extension direction of the channel is parallel to or coincides with the extension direction of the aerosol generating device. The collection unit can be used to collect condensate. At least a part of the collection unit is fixedly disposed on the inner wall of the cylinder 71. From the radial direction perpendicular to the channel, the collection unit can at least cover the channel of the cylinder 71. The collection unit connects the space where the flow rate adjustment mechanism 5 is located and the space where the heating component 4 is located, that is, the medium can enter the channel from one end of the channel and flow out from the other end of the channel.

[0067] In this embodiment, viewed from the radial direction perpendicular to the channel, the collection unit covers the channel of the cylinder 71, so that the aerosol condensate will not drip onto the surface of the flow rate regulating mechanism 5 due to the obstruction of the collection unit, thus preventing the flow rate regulating mechanism 5 from short-circuiting and improving the reliability of the flow rate regulating mechanism 5. The collection unit connects the space where the flow rate regulating mechanism is located and the space where the heating component is located, which can ensure the smooth flow of air between the heating component 4 and the flow rate regulating mechanism 5, so that the medium can enter the channel from one end of the channel and flow out from the other end of the channel.

[0068] In this embodiment of the utility model, such as Figure 5 As shown, the path adjustment mechanism 7 also includes a support member 72. The collecting unit includes multiple helical blades 73. The support member 72 is located in the middle of the cylinder 71 and is used to support the helical blades 73. Preferably, the centerline of the support member 72 coincides with the centerline of the cylinder 71. This centerline is a virtual, non-existent line and is the axis of symmetry of the cylinder 71 or the support member 72. The helical blades 73 include a first blade edge 731 fixed to the support member 72, a second blade edge 732 fixed to the inner wall of the cylinder 71, and a blade surface 733 connecting the first blade edge 731 and the second blade edge 732. The helical blades 73 are spirally ascending around the support member 72. The first blade edges 731 of the multiple helical blades 73 are staggered in the axial or circumferential direction of the support member 72. Figure 6 As shown, multiple helical blades 73 completely cover the channel of the cylinder 71.

[0069] Specifically, the staggered arrangement of the first blade edges 731 of the plurality of helical blades 73 in the axial direction of the support member 72 as described in this embodiment means that the starting points of the first blade edges 731 of the helical blades 73 on the support member 72 are axially spaced.

[0070] The staggered arrangement of the first blade edges 731 of the plurality of helical blades 73 in the circumferential direction of the support member 72, as described in this embodiment, means that the starting points of the first blade edges 731 of the helical blades 73 on the support member 72 are circumferentially spaced. Preferably, the plurality of helical blades 73 have the same rotation angle and the starting points of the first blade edges 731 are located on the same radial plane of the support member 72 (a plane perpendicular to the axial direction of the cylinder 71 is a radial plane) (for example, such as...). Figure 5 As shown, A and B are the starting points of the first blade edge 731 of the two helical blades 73 (rotation angle of 180°) on the support member 72, respectively. The two starting points A and B are located on the same radial plane. This is beneficial to shorten the axial length of the cylinder 71 and make full use of the internal space of the cylinder 71, which is conducive to the miniaturization of the aerosol generating device. At the same time, it also improves the symmetry of the airflow at the outlet of the path adjustment mechanism 7, which is beneficial to improve the uniformity of subsequent heating. Furthermore, when the sum of the rotation angles of the multiple helical blades 73 is 360°, the axial length of the cylinder 71 can be set to the shortest, that is, the same multiple helical blades 73 can just completely cover the channel of the cylinder 71.

[0071] The fact that multiple helical blades 73 completely cover the channel of cylinder 71 means that, from a top-down and / or bottom-up perspective, multiple helical blades 73 completely cover the channel of cylinder 71. In other words, the area of ​​the projected surface of multiple helical blades 73 on the radial plane of cylinder 71 is the same as the area of ​​the radial plane of the channel of cylinder 71, thereby blocking aerosol condensate that may fall from above.

[0072] Combination Figure 5 , Figure 6 As shown, Figure 6 The diagram shows the starting edge 734 and the ending edge 735, which can be understood as the starting edge 734 and the ending edge 735 of the left helical blade 73; while the starting edge 734 and the ending edge 735 of the right helical blade 73 coincide with the corresponding edge of the left helical blade 73 in the radial plane, and are not shown in the diagram. Alternatively, it can be understood as the starting edge 734 and the ending edge 735 of the right helical blade 73; while the starting edge 734 and the ending edge 735 of the left helical blade 73 coincide with the corresponding edge of the right helical blade 73, and are not shown in the diagram. Through the above arrangement, the area of ​​the projection surface of the multiple helical blades 73 on the radial plane of the cylinder 71 is the same as the area of ​​the radial plane of the channel of the cylinder 71, achieving complete coverage of the channel. In the above description, "left" and "right" correspond to the left and right directions when the observer is viewing the paper from the front.

[0073] In this embodiment, the starting edge 734 may be close to the heating component 4 and the ending edge 735 may be close to the flow rate regulating mechanism 5, or the starting edge 734 may be close to the flow rate regulating mechanism 5 and the ending edge 735 may be close to the heating component 4.

[0074] In some embodiments, the collecting unit may also include only one helical blade 73. The first edge 731 of the helical blade 73 is fixed to the support member 72, and the second edge 732 of the helical blade 73 is fixed to the inner wall of the cylinder 71. The helical blade 73 spirals upward around the support member 72, and the helical blade 73 rotates at least 360° around the support member 72 to completely cover the channel inside the cylinder 71. This structure is simple and easy to process and manufacture.

[0075] In this embodiment, by setting the helical blades 73, the airflow is guided to forcibly ascend along the fixed helical blades 73 through the isolation space 6 in a spiral path. This causes the airflow to change from a traditional axial flow to a high-speed rotating vortex after leaving the isolation space 6. This change in airflow pattern causes the airflow to move in a spiral trajectory within the heating zone where the heating component 4 is located and the heat exchange zone where the aerosol-generating product is located, extending the flow path length in both zones and improving the heat exchange effect. Furthermore, the airflow generates centrifugal force during its flow through the helical blades 73, pushing the air towards the periphery of the heating component 4 and the aerosol-generating product. This facilitates full heating of the aerosol-generating product and alleviates the problem of uneven heating. The first blade edges 731 of multiple helical blades 73 are staggered in the axial or circumferential direction of the support member 72. There is a gap between the helical blades 73 in the axial direction, so that the isolation space 6 is not affected by the presence of the helical blades 73, thus ensuring smooth airflow. By covering the channel of the cylinder 71 with multiple helical blades 73, the aerosol condensate will not drip onto the surface of the flow rate regulating mechanism 5 under the obstruction of the helical blades 73, preventing the flow rate regulating mechanism 5 from short-circuiting and improving the reliability of the flow rate regulating mechanism 5.

[0076] like Figure 4 As shown in the figure, this embodiment uses simulation software to simulate the above working conditions. As can be seen from the figure, the air blown up from the bottom will turn into a spiral airflow and maintain a certain flow rate.

[0077] In this embodiment, the number of spiral blades 73 is not limited; it can be one, two, or more. (Combined with...) Figure 5 , Figure 6 As shown, when there are two helical blades 73, the rotation angle of a single helical blade 73 is 180°. Combined with... Figure 18As shown, when the number of spiral blades 73 is 2, there are two airflow inlets and outlets (arrows indicate the airflow direction, and the number of arrows indicates the number of outlets). When the number of spiral blades 73 is 1, there is one airflow inlet and one airflow outlet. Multiple airflow inlets or multiple airflow outlets are beneficial to improving the symmetry of the airflow at the outlet of the path adjustment mechanism 7, thereby improving the uniformity of heating of the aerosol-generated product heated by the airflow.

[0078] In this embodiment, the number of spiral turns of the helical blade 73 is not limited, and technicians can choose an appropriate number of spiral turns according to actual needs. Considering that the size of the aerosol generating device is usually not particularly large, the number of spiral turns of the helical blade 73 can be half a turn, one turn, two turns, three turns, etc. An appropriate number of spiral turns is beneficial to obtaining more rotational kinetic energy. The higher the rotational speed, the more stable and longer the rotational state, which helps to resist downstream attenuation.

[0079] In the above embodiment, when the airflow flows out of the isolation space 6, its rotational kinetic energy decreases as the path length increases. To ensure that the airflow maintains a spiral ascent in the area where the heating component 4 is located and the area of ​​the receiving cavity 3, the length of the isolation space 6, the length of the space where the heating component 4 is located, the length of the receiving cavity 3 (the heat exchange length of the aerosol-generated product), the initial velocity of the airflow at the outlet of the heating component 4, the receiving cavity 3, and the flow rate regulating mechanism 5 should be reasonably controlled. By controlling the length of the isolation space 6, the airflow can gain more rotational kinetic energy by spiraling upward through the spiral blades 73 within the isolation space 6. By controlling the length of the heating component 4, the residence time of the airflow in the heating area can be controlled to obtain more thermal energy. By controlling the length of the receiving cavity 3, the aerosol-generated product in the receiving cavity 3 can have a better heat exchange effect. In this embodiment, the ratio of the lengths of the isolation space 6, the heating component 4, and the receiving cavity 3 in the direction of the support member 72 is: length of isolation space 6: length of heating component 4: length of receiving cavity 3 = 1.1~1.5:1:1~1.2. In this embodiment, the length of the isolation space 6 is greater than the length of the heating component 4, providing space for stable airflow rotation. This proportional setting facilitates uniform heating, avoids localized overheating, and reduces energy waste. In the above embodiment, the outlet flow velocity of the flow rate regulating mechanism 5 is 1.2-1.5 m / s. If the outlet flow velocity of the flow rate regulating mechanism 5 is too low, it may lead to insufficient kinetic energy and easy attenuation of the swirling flow. If the flow velocity is too high, the time spent flowing through the spiral blades 73 is too short, insufficient time for complete rotation, and high-speed flow through the heating zone may result in insufficient heating. A flow velocity within the above range can balance the kinetic energy of the swirling flow with sufficient heating, improving heat exchange efficiency and user experience.

[0080] In the above embodiment, the second blade edge 732 is arc-shapedly connected to the inner wall of the cylinder 71. By making the second blade edge 732 arc-shapedly connected to the inner wall of the cylinder 71, a smooth geometric transition is provided, which can smoothly guide the flow of aerosol condensate, reduce flow resistance, and prevent the condensate from "getting stuck" at the intersection of the inner wall of the cylinder 71 and the second blade edge 732 (when there is a sharp angle between the inner wall of the cylinder 71 and the second blade edge 732, aerosol is prone to condensation and accumulation at the angle); and the arc-shaped connection between the second blade edge 732 and the inner wall of the cylinder 71 reduces the processing difficulty and improves the convenience of cleaning at this location.

[0081] In some embodiments, the condensate can be retained by roughening the surface of the spiral blade 73, or by making the second blade edge 732 and the inner wall of the cylinder 71 a straight line connection so that the aerosol condenses and accumulates at the angle, or by a combination of the above-mentioned techniques for retaining the condensate.

[0082] In the above embodiment, the first blade edge 731 is closer to the heating element 4 than the second blade edge 732. For example... Figure 7 As shown, by bringing the first blade edge closer to the heating element 4, so that in Figure 7 In the cross-sectional diagram shown (the section line passes through the axis of symmetry of the support 72), the first blade edge 731 is always higher than the second blade edge 732. Consequently, the angle between the inner wall of the cylinder 71 and the blade surface 733 is always an acute angle α, which is beneficial for guiding the accumulation of aerosol condensate. In an optional embodiment, the value of α ranges from 20° to 70°. By controlling α within the above range, it is possible to avoid greater airflow resistance due to an excessively large angle, ensuring better airflow efficiency while also taking into account the guiding capacity of the aerosol condensate.

[0083] In the above embodiments, continue to refer to Figure 6 The path adjustment mechanism 7 also includes a stop portion 736 protruding from the blade surface 733, with both ends of the stop portion 736 connected to the first blade edge 731 and the second blade edge 732, respectively. The stop portion 736 prevents further flow of aerosol condensate, causing the condensate to accumulate near the stop portion 736, thus achieving condensate collection. In this embodiment, the stop portion 736 does not alter the communication between the isolation space 6 and the space where the heating component 4 is located, as well as the space where the flow rate adjustment component is located, ensuring smooth airflow.

[0084] In some embodiments, a storage groove (not shown in the figure) may be provided on the blade surface 733 to store aerosol condensate, and is not limited to the form of a stop portion 736 protruding from the blade surface 733.

[0085] In the above embodiments, such as Figure 8As shown, the path adjustment mechanism 7 includes multiple mechanisms distributed along the axial direction of the cylinder 71, and these mechanisms are detachably connected. In this embodiment, the distribution of multiple path adjustment mechanisms along the axial direction of the cylinder 71 extends the airflow path length, improves the stability of the airflow output, and also extends the path length of the condensate. The detachable connection of the multiple path adjustment mechanisms 7 facilitates subsequent maintenance, cleaning, and replacement, improving ease of use.

[0086] Specifically, if a single path regulating mechanism 7 is used, there is still a certain probability that fine aerosol condensate will drift through the ventilation section between the spiral blades 73 and contaminate the motor and fan (airflow disturbance component 53) in the flow rate regulating mechanism 5. Therefore, by using at least two path regulating mechanisms 7 stacked in a staggered manner, even if fine aerosol condensate passes through the ventilation section of the first path regulating mechanism 7, due to the staggered stacking, this aerosol condensate will fall into the spiral blade 73 area of ​​the second path regulating mechanism 7 and be blocked. The second path regulating mechanism 7 also has the function of storing condensate, so at least two such path regulating mechanisms 7 can also effectively collect condensate and protect the flow rate regulating mechanism 5. In this embodiment, the two path regulating mechanisms 7 can be staggered by 90° or other angles, or not staggered at all. The staggering described in this embodiment can be understood as the end edge 735 of the spiral blade 73 of the upper path regulating mechanism 7 and the starting edge 734 of the spiral blade 73 of the lower path regulating mechanism 7 having a certain angle rather than being parallel or overlapping. In some embodiments, a high-temperature resistant silicone sleeve 74 can be fitted onto the outside of the two path adjustment mechanisms 7 to ensure the stability of the connection between them.

[0087] In the above embodiments, the two path adjustment mechanisms 7 can be detachably connected by snap-fit. This utility model does not limit this, as long as it is easy to install and remove.

[0088] In the above embodiments, the path adjustment mechanism is detachably connected to the heating component, and the path adjustment mechanism can also be detachably connected to the flow rate adjustment mechanism to facilitate cleaning or replacement of the path adjustment mechanism.

[0089] In the above embodiment, a through groove (not shown in the figure) is provided inside the support member 72, which connects the space where the flow rate regulating mechanism 5 is located and the space where the heating component 4 is located. By providing a through groove in the middle of the support member 72, a portion of the airflow can reach the heating component 4 through the through groove, thereby improving the airflow efficiency. In some embodiments, a baffle may also be provided at one end of the through groove near the flow rate regulating mechanism 5 to prevent condensate in the through groove from flowing into the flow rate regulating mechanism 5 below.

[0090] In the above embodiments, a vortex ring stabilizer (not shown in the figure) is also included, disposed between the path adjustment mechanism 7 and the heating component 4. The vortex ring stabilizer can "shape" and "reinforce" the airflow at the outlet of the flow rate adjustment mechanism 5 or the helical blade 73, preventing the airflow from attenuating too much before entering the heating component 4, thereby increasing the path length of the airflow in the heating area and the heat exchange area and improving the heat exchange effect.

[0091] In some embodiments, the path adjustment mechanism 7 may also be a combination of a separate vortex ring stabilizer and a separate aerosol condensate storage tank.

[0092] In some embodiments, the path adjustment mechanism 7 is a porous structure (not shown in the figure), configured with micropores through which airflow passes. These micropores adsorb condensed aerosols via capillary action. Specifically, the porous structure can be a porous ceramic plate. When high-temperature aerosols flow through the microporous channels of the cooler porous ceramic, they cool and liquefy, forming tiny droplets. These micropores exert strong capillary forces on the liquid, rapidly drawing it into the micropores and trapping it firmly. Even if the device is tilted or inverted, gravity cannot easily overcome the capillary forces to expel the liquid. Since the viscosity of the gas is much lower than that of the liquid, the airflow can pass relatively smoothly through the micropores partially occupied by the liquid, while the liquid remains trapped.

[0093] In some embodiments, such as Figure 9 , Figure 10 As shown, the collection unit of the path adjustment mechanism 7 includes at least: a first layer of guide member 75 and a second layer of guide member 76. The first layer of guide member 75 is fixedly connected to the inner wall of the cylinder 71. The first layer of guide member 75 and the inner wall of the cylinder 71 form a first receiving tank 751 for collecting condensate. The opening of the first receiving tank 751 faces the heating component 4. The second layer of guide member 76 is fixedly connected to the inner wall of the cylinder 71 and is located on the side facing the flow rate adjustment mechanism 5 relative to the first layer of guide member 75. The second layer of guide member 76 and the inner wall of the cylinder 71 form a second receiving tank 761 for collecting condensate. The opening of the second receiving tank 761 faces the heating component 4. From the radial direction perpendicular to the channel, the second layer of guide member 76 and the first layer of guide member 75 completely cover the channel of the cylinder 71. There is a gap between the second layer of guide member 76 and the first layer of guide member 75 in the extending direction of the cylinder 71 for airflow to pass through.

[0094] In this embodiment, as Figure 11As shown, the first layer of guide members 75 and the second layer of guide members 76 maintain a preset distance in the axial direction of the cylinder 71, which facilitates the flow of air within the gap between the first layer of guide members 75 and the second layer of guide members 76, thereby increasing the kinetic energy of the airflow. The first layer of guide members 75 and the second layer of guide members 76, together with the inner wall of the cylinder 71, form a first receiving tank 751 and a second receiving tank 761 for collecting condensate, respectively, simplifying the structure of the collection unit. Furthermore, the openings of the first receiving tank 751 and the second receiving tank 752 are upward-facing, which on the one hand can collect the aerosol condensate falling from above, and on the other hand allows the airflow to flow upward along the surface of the corresponding guide members, improving the stability of the airflow. Figure 12 As shown in the top view, the projection surfaces of the first layer of guide members 75 and the second layer of guide members 76 in the radial direction (the surface perpendicular to the radial direction of the cylinder 71) cover the channel of the cylinder 71, thus providing a larger aerosol condensate receiving surface inside the cylinder 71. Aerosol condensate that does not fall into the first receiving tank 751 can be received by the second receiving tank 761, which helps to prevent aerosol condensate from entering the flow rate regulating mechanism 5 below through the gap between the first layer of guide members 75 and the second layer of guide members 76. Alternatively, the collection unit may also include at least a third layer of guide members fixedly connected to the inner wall of the cylinder 71. The third layer of guide members and the inner wall of the cylinder 71 form a third receiving tank for collecting condensate. The opening of the third receiving tank faces the heating component. The third layer of guide members is located between the second layer of guide members and the flow rate regulating mechanism 5. From the top view, the projection surfaces of the first layer of guide members, the second layer of guide members and the third layer of guide members in the radial direction (the surface perpendicular to the radial direction of the cylinder 71) cover the channel of the cylinder 71, so that aerosol condensate that does not fall into the first receiving tank can be received by the second receiving tank, and aerosol condensate that does not fall into the second receiving tank can be received by the third receiving tank.

[0095] In some embodiments, the ends of the first guide member 75 and the second guide member 76 near the heating member 4 extend vertically along the axial direction, which is beneficial for better guiding the airflow.

[0096] In the accompanying drawings of this embodiment, there is one first-layer guide member 75 and one second-layer guide member 76. In some embodiments, there may be multiple first-layer guide members 75 and multiple second-layer guide members 76. The first-layer guide members 75 are spaced apart in the circumferential direction of the cylinder 71, and the second-layer guide members 76 are spaced apart in the circumferential direction of the cylinder 71. The first-layer guide members 75 and the second-layer guide members 76 are arranged alternately in the circumferential direction of the cylinder 71 (the first-layer guide member 75, the second-layer guide member 76, the first-layer guide member 75, and so on).

[0097] In some embodiments, the heating element 4 may also be a hollow tube, with the hollow tube structure docking with the isolation space 6. The hollow tube shape of the heating element 4 helps to reduce the resistance to the airflow at the outlet of the isolation space 6, thereby maintaining the spiral upward posture of the airflow at the outlet of the isolation space 6, further ensuring the heating effect between the heating element 4 and the air, as well as the heat exchange effect between the hot air and the aerosol-generated product. In some embodiments, the heating element 4 may also be a heating wire.

[0098] In the above embodiments, such as Figure 8 , 9 , Figure 14 As shown, the flow rate regulating mechanism 5 includes: a motor base 51, a motor 52, and an airflow disturbance component 53. The motor base 51 has a hollow interior forming a motor mounting cavity 510. The motor 52 is fixedly installed in the motor mounting cavity 510, and the output end of the motor 52 extends toward the heating component 4. The airflow disturbance component 53 is fixed to the output end of the motor 52 and is located between the motor base 51 and the heating component 4.

[0099] Specifically, the motor base 51 is preferably made of an elastic base that can absorb vibration. By setting an elastic base, the vibration generated by the fan rotation can be absorbed, improving the user experience. The airflow disturbance component 53 is a fan, which is driven by the motor 52 to rotate and disturb the airflow within the aerosol generating device. The flow rate adjustment mechanism 5 in this embodiment has a simple structure, is easy to install and manufacture, and helps to save on the cost of the aerosol generating device.

[0100] In the above embodiment, the heating component 4 is located above the output end of the motor 52 in the extending direction. This arrangement of components along the axial direction of the housing 2 helps to reduce the diameter of the aerosol generating device and improves ease of use.

[0101] In the above embodiments, the distance between the airflow disturbance component 53 and the heating component 4 is 2mm to 10mm. The distance between the airflow disturbance component 53 and the heating component 4 should not be too close to avoid damage from high temperature, nor should it be too far to avoid requiring a larger initial velocity to fully blow hot air into the smoke. Generally, the distance from the fan to the bottom of the heating component 4 is preferably 3 to 5mm.

[0102] In the above embodiments, continue to refer to Figure 13The motor base 51 includes a base portion 511 and a mounting portion 512. The base portion 511 has a hollow structure that communicates with the outside. The mounting portion 512 is located closer to the airflow disturbance member 53 than the base portion 511. That is, in this embodiment, the mounting portion 512 is located above the base portion 511. The hollow interior of the mounting portion 512 forms a motor mounting cavity 510. The circumferential surface of the mounting portion 512 has a plurality of protrusions 513 extending along the axial direction of the mounting portion 512. Adjacent protrusions 513 define a channel 514 for airflow to pass through. The channel 514 communicates with the hollow structure. The plurality of protrusions 513 are partially embedded inside the base portion 511 and fixedly connected to the inner wall of the base portion 511.

[0103] In the above embodiment, a sealing ring 54 is sleeved on the outside of the seat 511, and annular ribs 541 distributed in the axial direction of the sealing ring 54 are formed on the circumferential surface of the sealing ring 54. The arrangement of the annular ribs 541 can improve the sealing performance between the seat 511 and the housing 2 of the aerosol generating device, as well as the stability of the motor base 51.

[0104] In the above embodiments, such as Figure 15 As shown, it also includes a base bracket 55, which is installed in the hollow structure of the base portion 511. The base bracket 55 has the same protrusions and channels as the mounting portion 512. The arrangement of the base bracket 55 helps to prevent the transfer of internal heat to the external environment.

[0105] In the above embodiments, such as Figure 8 , Figure 13 , Figure 16 As shown, it also includes: a main sleeve 9, which is fitted onto the outside of the motor base 51 and extends to surround the airflow disturbance member 53. The inner surface of the main sleeve 9 that fits onto the motor base 51 matches the outer periphery of the protrusion 513. The main sleeve 9 prevents airflow diffusion and enhances the rotational kinetic energy of the airflow by concentrating it. Furthermore, the upper end of the main sleeve 9 is fitted onto the outside of the path adjustment mechanism 7. The inner diameter of the portion of the main sleeve corresponding to the path adjustment mechanism 7 is larger than the portion of the main sleeve connected to the flow rate adjustment mechanism 5. The connection between the path adjustment mechanism 7 and the flow rate adjustment mechanism 5 via the main sleeve 9 improves the stability of the device.

[0106] In the above embodiments, such as Figure 17 As shown, it also includes: a connecting cylinder 8, having a first receiving groove 81 and a second receiving groove 82 that are connected in the axial direction. The first receiving groove 81 is used to receive the aerosol generating product, and the second receiving groove 82 is used to receive the heating component 4. A partition 83 is provided between the first receiving groove 81 and the second receiving groove 82. A through hole 831 is provided on the partition 83 to connect the first receiving groove 81 and the second receiving groove 82. The second receiving groove 82 is closer to the airflow disturbance component 53 than the first receiving groove 81.

[0107] Furthermore, the connecting sleeve 8 also includes a third receiving groove 84, which is sleeved on the end of the path adjustment mechanism 7 near the heating component 4. The connecting sleeve 8 connects the receiving cavity 3, the heating component 4, and the path adjustment mechanism 7, improving the connection stability of the internal structure of the aerosol generating device. In this embodiment, the connecting sleeve 8 has a first wire passage notch 85 at the upper end of the heating component 4, and a second wire passage notch 86 at the junction of the heating component 4 and the path adjustment mechanism 7. The heating component 4 is a heating wire, and the lead wire connecting the heating wire to the power supply passes through the first wire passage notch 85 and enters the second wire passage notch 86. The lead wire passes through the interior of the heating component 4, which reduces the influence of the lead wire on the airflow inside the connecting sleeve 8, improves the rationality of the layout, and also facilitates the subsequent cleaning of the path adjustment mechanism 7 and the flow rate adjustment mechanism 5. In this embodiment, the path adjustment mechanism 7 and the flow rate adjustment mechanism 5 can be manufactured as a whole for easy installation and disassembly.

[0108] In some embodiments, in order not to affect the consumer's user experience, the initial velocity of the hot air at the outlet of the heating component 4 and the length of the receiving cavity 3 are configured such that when the air flows to the upper end of the aerosol-generating article, the flow velocity perpendicular to the consumer's use direction is almost 0.

[0109] In the above embodiment, when a suction action is detected, the flow rate adjustment mechanism 5 stops working. At this time, the airflow is provided by the negative pressure generated by the consumer's suction. On the one hand, this can reduce the energy consumption of the fan, and on the other hand, it can also ensure the consumer's suction experience (because the flow rate adjustment mechanism 5 does not work at this time, and the suction sensation is the same as other devices).

[0110] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
