[0029] To provide a clearer understanding of the technical features, objectives, and effects of this application, the specific embodiments of this application are now described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "up", "down", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings or the orientation or positional relationship commonly used when the product of this application is in use.

Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0034] Figures 1 to 6 An aerosol generating device 1 according to the first embodiment of this application is shown. This device can heat an aerosol generating article 2 inserted therein at a low temperature to release the aerosol in the aerosol generating article 2 without combustion. The aerosol generating device 1 may include a housing 10, a heating element 20, and a support member 30. The heating element 20 and the support member 30 are disposed within the housing 10. The heating element 20 can heat and atomize the aerosol generating article 2 after being powered on. The support member 30 is disposed at one end of the heating element 20 and is used to support the heating element 20 and the aerosol generating article 2 located within the heating element 20.

[0035] It should be understood that the aerosol generating device 1 can be used in the fields of medical, beauty, health care, and electronic atomization. The aerosol generating product 2 can use a solid matrix, which may include solid sheet-like, filamentous, or leaf-like atomizing materials. Specifically, it may include one or more of the following: powder, granules, fragments, strips, or flakes of tobacco, vanilla leaves, tea leaves, mint leaves, or other plant leaves. The atomizing material may also contain additional volatile flavor compounds to be released when the matrix is ​​heated. Of course, the aerosol generating product 2 may also include a liquid matrix or a paste matrix, such as oils or liquid medicines with added flavoring components.

[0036] like Figures 1 to 3 As shown, the housing 10 is generally a longitudinally elongated hollow cylinder, with an insertion port 11 at one end for inserting the aerosol generating article 2. The aerosol generating article 2 is cylindrical, and the heating element 20 defines a cylindrical heating space 200, one end of which can be connected to the insertion port 11. The aerosol generating article 2 can be inserted into the heating space 200 through the insertion port 11 to be heated by the heating element 20.

[0037] Understandably, the housing 10 can also be configured as a polygonal column, an elliptical column, an irregular column, an ellipsoid, a sphere, an irregular shape, or other shapes. The insertion port 11 can also be located on the side of the housing 10 or other positions. The aerosol generating product 2 and the heating space 200 can also be configured as elliptical columns, flat sheets of various shapes, polygonal columns, irregular columns, or other shapes.

[0038] An air inlet 100 is defined on the side wall of the housing 10. The heating element 20 may have an air inlet end 20M and an air outlet end 20N that penetrate the heating space 200. The air inlet 100 can be connected to the heating space 200 for air intake through the air inlet end 20M. The air outlet end 20N of the heating element 20 is located at the socket 11 of the housing 10, and the heating space 200 can be connected to the outside for air intake through the socket 11. That is, the heating space 200 can be connected to the air inlet 100 and the socket 11 respectively, forming an airflow channel P that is open at both ends, so as to output aerosol for user use.

[0039] Compared to setting the air inlet 100 at one end of the housing 10, this application sets the air inlet 100 on the side wall of the housing 10, which can shorten the distance between the air inlet 100 and the air inlet end 20M, shorten the air intake path, thereby reducing the proportion of cold air inhaled by the user in the first breath, improving the overall aerosol carry-out efficiency, and thus improving the user experience.

[0040] It should be understood that aerosol generating product 2 will produce condensate and other stains during the suction process. For aerosol generating devices with a bottom air intake structure and a straight air passage in related technologies, the condensate generated during use will remain in the straight air passage. If it is not cleaned, it will affect the suction taste.

[0041] By placing the air inlet 100 on the side wall of the housing 10, this application allows at least a portion of the air inlet section of the airflow channel P to extend at an angle to the axial direction of the heating space 200. That is, the airflow channel P can be curved or bent to prevent a large amount of condensate from entering the air inlet section of the airflow channel P, thereby ensuring that the suction experience is not affected.

[0042] It should be understood that, for aerosol generating devices with a top-inlet U-shaped air passage in related technologies, the aerosol generated during the preheating stage is prone to leakage through the air inlet end of the U-shaped air passage, resulting in waste.

[0043] This application provides an air inlet 100 on the side wall of the housing 10 and connects it to the heating space 200 via the air inlet end 20M of the heating component 20, thereby enabling the air inlet section of the airflow channel P to be located at the upstream end of the heating space 200, reducing aerosol leakage during the preheating stage.

[0044] Furthermore, such as Figure 2 and Figure 3 As shown, the air inlet 100 is positioned on the side wall of the housing 10 such that it corresponds to the air inlet end 20M of the heating component 20 along the axial direction of the housing 10, so as to further shorten the distance between the two and reduce the length of the air inlet path.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments, the heating element 20 may be cylindrical. A support member 30 is disposed at the air inlet end 20M of the heating element 20 and defines a support space 300 and at least one first air guide hole 311. One end of the support space 300 is open to connect and communicate with the heating space 200, forming an integral chamber. At least a portion of the aerosol generating article 2 can be inserted into this chamber. The first air guide hole 311 can communicate with the air inlet 100, the support space 300, and the heating space 200 respectively.

[0046] For example, such as Figure 2As shown, the aerosol generating article 2 may include a medium section 201, a sealing section 202, and a suction section 203. The medium section 201 is coaxially disposed between the sealing section 202 and the suction section 203. When the aerosol generating article 2 is inserted into the chamber, at least a portion of the sealing section 202 is located within the support space 300, at least a portion of the medium section 201 is located within the heating space 200, and at least a portion of the suction section 203 is located outside the chamber.

[0047] By setting up the support member 30 and defining the support space 300, this application allows the airflow channel P to be redirected at the support space 300, which can prevent condensate from leaking into the air intake section of the airflow channel P, thus ensuring the suction experience. At the same time, the setting of the support space 300 can also prevent the blocking section 202 from being heated in the heating space 200, thereby improving the utilization rate of the heating space 200.

[0048] Specifically, please refer to the following: Figure 5 and Figure 6 The support member 30 is generally cylindrical with one end open, and includes a bottom wall and a side wall. The bottom wall seals one end of the side wall, and together they define a support space 300 with one end open. A stepped surface 312 is formed on the inner wall surface of the side wall away from the bottom wall, which is used to abut against the air inlet end 20M of the heating element 20 to achieve coaxial assembly of the two.

[0049] It should be understood that the air inlet 100 corresponds to the air inlet end 20M of the heating element 20 along the axial direction of the housing 10. This can be understood as the air inlet 100 and the first air guide hole 311 being correspondingly arranged in the axial direction of the housing 10. This arrangement greatly shortens the formation of the air inlet section in the airflow channel P, thereby minimizing the proportion of cold air drawn in the first inlet and improving the overall aerosol carry-out efficiency.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the air inlet section of the airflow channel P may include a third air passage P3, which may be located within the support member 30 and communicate with the support space 300 and at least one first air guide hole 311. When the aerosol generating article 2 is inserted into the support space 300, the third air passage P3 can prevent the air inlet end of the aerosol generating article 2 from being blocked, ensuring smooth suction.

[0051] Specifically, the support member 30 may include a main body 31 and at least one support structure 32. The main body 31 defines a support space 300, a first air vent 311, and a stepped surface 312. The support structure 32 is disposed within the main body 31 and, together with the main body 31, defines a third air passage P3.

[0052] For example, continue reading Figure 2 and Figure 3 The support structure 32 protrudes from the connection between the bottom wall and the side wall of the main body 31 and is used to abut against the aerosol generating product 2. The space between the support structure 32 and the main body 31 can be regarded as the third air passage P3. When the aerosol generating product 2 is inserted into the aerosol generating device 1, the air inlet end of the aerosol generating product 2 (that is, the end of the sealing section 202 away from the medium section 201) can be at least partially exposed in the third air passage P3. Therefore, the airflow can follow the user's suction and enter the aerosol generating product 2 through the third air passage P3 to carry away the aerosol formed by internal atomization for the user's use.

[0053] It should be understood that the support structure 32 can be configured as various shapes such as columnar, block, disc, or irregular. It can also protrude from the inner wall of the bottom wall of the main body 31 or from the inner wall of the side wall. The number of it can also be set to multiple, spaced apart within the main body 31, without specific limitation here.

[0054] In some other alternative embodiments, at least one groove may be recessed on the bottom wall of the main body 31, the groove communicating with the first air guide hole 311 and the groove opening communicating with the support space 300. This groove can be regarded as the third air passage P3.

[0055] like Figure 6 As shown, in some embodiments, the main body 31 may include a support portion 3101 and an air guide portion 3102. A portion of the air guide portion 3102 forms the bottom wall of the main body 31. The support portion 3101 is tubular and, together with a portion of the air guide portion 3102, forms the side wall of the main body 31. The air guide portion 3102 and the support portion 3101 together define the support space 300, and the support structure 32 is disposed on the support portion 3101.

[0056] Furthermore, the outer diameter of the air guide 3102 can be larger than the outer diameter of the support 3101. When the support 30 and the heating element 20 are assembled into the housing 10, the portion of the air guide 3102 that protrudes radially outward from the support 3101 can also abut against part of the heating element 20 to improve the stability of the support for the heating element 20.

[0057] It should be understood that the support part 3101 and the air guide part 3102 can be detachably or non-detachably assembled with each other through snap-fit ​​connection, threaded connection, plug-in connection, interference fit, etc., or they can be integrally molded. The support part 3101 or the air guide part 3102 can also be composed of a single structure, or can be formed by detachably or non-detachably assembling with each other through snap-fit ​​connection, threaded connection, plug-in connection, interference fit, etc., and no specific limitation is made here.

[0058] In some embodiments, the heating component 20 may include a pot body and a heating structure disposed on the pot body. The pot body may be made of a heat-resistant material, such as quartz, ceramic, or heat-resistant glass. The heating structure may be layered or mesh-like and disposed on the inner and / or outer walls of the pot body; it may specifically employ resistance wire, infrared radiation coating, etc., without specific limitations.

[0059] like Figure 4 As shown, in some embodiments, there can be multiple first air guide holes 311, which are evenly spaced and arranged circumferentially on the support member 30. The air intake section of the airflow channel P may include a first air passage P1, which may be an annular air passage arranged circumferentially between the housing 10 and the support member 30, and communicates with the air inlet hole 100 and the first air guide holes 311 respectively.

[0060] The arrangement of the first air passage P1 and multiple first air guide holes 311 can improve the uniformity of airflow entering the aerosol-generating product 2 during the suction process, preventing airflow from concentrating on one side and affecting the suction experience. Simultaneously, it can reduce the risk of blockage in the air intake section of the airflow passage P.

[0061] Of course, the multiple first air guide holes 311 can also be non-uniformly spaced in the circumferential direction of the support member 30. The number of the first air guide holes 311 can be set to one, two, three, four, five, etc., and is not specifically limited here.

[0062] Furthermore, such as Figure 2 and Figure 3 As shown, the aerosol generating device 1 may further include a first sealing element 40, which can be sleeved on the support element 30 and together with the support element 30 defines the first air passage P1. The setting of the first sealing element 40 can improve the relative sealing of the air inlet section of the airflow passage P, avoid air leakage during the suction process, and further reduce the proportion of cold air in the first inlet during the suction process, thereby improving the suction experience and the overall aerosol carry-out efficiency.

[0063] See also Figures 4 to 6 The first sealing element 40 may be annular in structure, interference-fitted onto the support 30, and defines at least one second air guide hole 41. The second air guide hole 41 may be connected to the first air passage P1 and the air inlet 100 respectively.

[0064] Specifically, a first air guide groove 313 is recessed inward on the outer periphery of the air guide portion 3102 of the main body 31 of the support member 30. The first air guide groove 313 is annular, and its outer peripheral opening forms an annular groove. A plurality of first air guide holes 311 are evenly spaced along the circumference and penetrate the groove wall of the first air guide groove 313 to connect the first air guide groove 313 with the support space 300. The position of the first sealing member 40 on the support member 30 can block the groove opening on the outer side of the first air guide groove 313 to define the first air passage P1.

[0065] In some other alternative embodiments, the first air guide groove 313 may also be formed on the inner wall of the first seal 40. Alternatively, the support 30 and the first seal 40 may each define a portion of the first air guide groove 313, and the two may be joined to form a first air passage P1.

[0066] like Figure 4 As shown, in some embodiments, the air intake section of the airflow channel P may further include a second air passage P2, which may communicate with the first air passage P1 for air delivery. See also... Figure 2 and Figure 3 The aerosol generating device 1 may further include a second sealing element 50, which is sandwiched between the first sealing element 40 and the housing 10, and together with the housing 10 defines a second air passage P2. The second air passage P2 can be connected to the second air guide hole 41 and the air inlet hole 100 respectively. During the user's suction process, outside air can sequentially pass through the air inlet hole 100, the second air passage P2, the second air guide hole 41, the first air passage P1, the first air guide hole 311, and the third air passage P3, and enter the cavity formed by the support space 300 and the heating space 200, so as to pass through the aerosol generating product 2 located in the cavity, carry away the aerosol inside it, and provide it to the user.

[0067] By setting the second seal 50 and the second air passage P2, any gaps that may exist at the connection between the second air guide hole 41 and the air inlet hole 100 can be sealed, further ensuring the relative sealing of the air intake section of the airflow passage P.

[0068] This application, by setting a first seal 40 and a second seal 50, constructs relatively circuitous first air passages P1 and second air passages P2, which can effectively prevent the backflow of condensate or residual aerosol generating medium, thereby further ensuring the cleanliness of the air intake section of the airflow channel P, improving the service life of the aerosol generating device 1, and enhancing the user's inhalation experience. Simultaneously, the circuitous air intake channel can further avoid aerosol leakage during the preheating stage, preventing aerosol waste. Furthermore, the multiple seals enhance airtightness while improving airflow stability and optimizing airflow flow, allowing the airflow to be more evenly distributed before entering the heating space 200, thereby improving atomization efficiency and flavor experience.

[0069] Furthermore, such as 4 to Figure 6 As shown, the second seal 50 can be interference-fitted between the first seal 40 and the housing 10, and at least two second air guide grooves 51 are defined on the side facing the housing 10. The side of the second air guide groove 51 facing the housing 10 opens to form its opening, which can be sealed by the housing 10 to form a second air passage P2. At least one third air guide hole 52 is also provided through the groove wall of the second air guide groove 51, and the third air guide hole 52 can be connected to the second air guide hole 41.

[0070] Specifically, the number of air inlets 100 can be set to two. The two air inlets 100 can be located approximately at both ends of the second air passage P2 along the circumference of the housing 10. By ensuring that the position of the air inlets 100 in the axial direction of the housing 10 corresponds to the first air guide hole 311, while increasing the number of air inlets 100, the air intake volume can be increased to avoid excessive suction resistance affecting the suction experience.

[0071] Of course, an air inlet 100 can be provided at the position corresponding to the housing 10 in the second air passage P2. That is, in this embodiment, the number of air inlets 100 can also be set to three, four, five, or more.

[0072] like Figure 5 and Figure 6 As shown, in some embodiments, the first sealing member 40 around the second air guide hole 41 and the second sealing member 50 around the third air guide hole 52 can be partially embedded to improve the relative sealing at the joint between the second air guide hole 41 and the third air guide hole 52.

[0073] In some other alternative embodiments, the second air guide groove 51 may also be formed on the inner wall surface of the housing 10. Alternatively, the housing 10 and the second seal 50 may each have a portion of the second air guide groove 51, which together form the second air passage P2.

[0074] In some other alternative embodiments, the support member 30 can also be directly interference-fitted between the housing 10 and the support member 30, and the second air guide hole 41 is correspondingly set with the air inlet hole 100, thereby achieving relative sealing between the two.

[0075] In some other alternative embodiments, the air inlet 100 can also be directly connected to the first air guide hole 311, and the connection between the two holes can be sealed by setting a sealing structure such as a sealing ring to ensure the air passage is airtight.

[0076] It should be understood that the first seal 40 and the second seal 50 can be connected and assembled to each other by means of interference fit, snap-fit ​​connection, integral molding, etc., without specific limitations. The first seal 40 and the second seal 50 can be made of one or more of the following materials: silicone, rubber, TPU (thermoplastic polyurethane), PCTG (polyethylene terephthalate copolymer), PPSU (polyphenylsulfone), PEEK (polyetheretherketone), etc., without specific limitations.

[0077] It should be understood that the first air passage P1, the second air passage P2, and the third air passage P3 are all positioned perpendicular to the axis of the housing 10 to shorten the stroke of the airflow passage P's intake section. Of course, their arrangement can also be at an angle of slightly less than 90° to the axis of the housing 10.

[0078] In some embodiments, the aerosol generating device 1 may further include a connector 60, which is generally cylindrical and sleeved on the end of the heating component 20 away from the support 30, so as to cooperate with the support 30 to limit the position of the heating component 20.

[0079] It should be understood that at the connection points between the connector 60 and the heating element 20 and the housing 10, at least one sealing ring 70 may be provided to ensure the sealing of the connection and prevent aerosol leakage.

[0080] In some embodiments, the aerosol generating device 1 may further include an electronic control component and a battery (not shown). The electronic control component and the battery are respectively disposed within the housing 10. The electronic control component is electrically connected to the heating component and the battery respectively, and is used to control the operation of the aerosol generating device 1. The battery is used to provide electrical energy for the operation of the aerosol generating device 1.

[0081] Figures 7 to 9 The aerosol generating device 1A in the second embodiment of this application is shown. The main difference between it and the aerosol generating device 1 in the first embodiment is that, in this embodiment, the aerosol generating device 1A does not include the first sealing member 40 and the second sealing member 50.

[0082] like Figure 8 As shown in Figure 9, in this embodiment, the first air guide groove 313A of the support member 30A and the housing 10A together define the first air passage P1A.

[0083] Furthermore, the number of air inlets 100A can be set to multiple, and they can be evenly spaced along the circumference of the housing 10A to improve the uniformity of airflow in the first air passage P1A, thereby ensuring the uniformity of air intake in each first air guide hole 311A.

[0084] It should be understood that the number and diameter of the air inlet 100A and the first air guide 311A ​​can be the same or different, and no specific limitation is made here.

[0085] like Figure 7 As shown, in some embodiments, at least one sealing ring 70A may be provided on each of the opposite sides of the first air guide groove 313A along the axial direction of the support member 30A. The sealing ring 70A may be sleeved on the support member 30A and radially interference-fitted between the support member 30A and the housing 10A to ensure the airtightness of the first air passage P1A.

[0086] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0087] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, any equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
