These devices typically provide aerosol to the user within twenty or fewer pumping cycles for a single aerosol product. However, during use, once heating begins, the user must complete twenty pumping cycles within a fixed timeframe, making it impossible to achieve on-demand aerosol release over extended periods.

[0009] Furthermore, at least two of the guide members are located on opposite sides of the heating cavity, and together with the cavity wall of the heating cavity, they define an airflow chamber.

[0010] Furthermore, at least two baffle structures are provided on the chamber wall of the heating chamber corresponding to at least two of the guide members, for reducing the gap between the guide members and the chamber wall of the heating chamber.

[0017] Implementing the technical solution constructed in this application has at least the following beneficial effects: This application, by setting up a heating chamber through which each region of the sheet-like aerosol generating product can pass sequentially, allows each region of the aerosol generating product to be heated independently. This enables users to use only the aerosol generated by a specific region of the aerosol generating product at a time. For other regions of the aerosol generating product, users can flexibly choose whether and when to use them according to their own needs, without having to use the aerosol generated by the entire aerosol generating product within a fixed time. This meets the user's need for on-demand release of aerosols over a long period of time, allowing for use and cessation of use as needed. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] 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. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] 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.

[0022] 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.

[0023] 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. "Below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] Figures 1 to 11The first embodiment of this application illustrates a microwave heating module 1, which, upon being powered on, heats the aerosol-generating product 2 by feeding microwaves, causing it to generate aerosols for user use. The microwave heating module 1 may include a housing unit 10, a microwave heating unit 20, an airflow guiding unit 30, and a medium traversal unit 40. The microwave heating unit 20, disposed within the housing unit 10, generates an energy field upon being powered on and fed microwaves, thereby heating the aerosol-generating product 2 located within the energy field. The medium traversal unit 40, also disposed within the housing unit 10, is used to place the aerosol-generating product 2 within the housing unit 10 and drive the aerosol-generating product 2 to move, ensuring that each area is sequentially heated by the microwave heating unit 20. The airflow guiding unit 30, disposed within the housing unit 10, works in conjunction with the housing unit 10 to define the airflow chamber 100. The airflow chamber 100 is connected to the air-guiding channels defined by the other structures of the microwave heating module 1, together forming an airflow channel that runs through both ends, so that the aerosol generated by the aerosol generating product 2 can flow out for user use.

[0025] like Figures 5 to 8 As shown, it should be understood that the aerosol generating product 2 can be in the form of a thin, elongated sheet or strip, housed within the housing unit 10. Each region along its length can pass sequentially through the microwave heating unit 20 under the drive of the medium traversal unit 40, where it is heated to generate aerosol. The aerosol generating product 2 can include an aerosol generating medium and at least one substrate layer along its thickness direction. The aerosol generating medium can be a solid material in the form of filaments, granules, or sheets made from plant leaves, flowers, and / or stems, and may also contain aroma components, propylene glycol, glycerol, or water. The substrate can be laid along the thickness direction on one side or opposite sides of the aerosol generating medium to improve the structural strength of the aerosol generating product 2. The substrate can be made of plant fiber (such as cardboard, greaseproof paper), polymer (such as plastics), metal, or inorganic non-metallic (such as ceramics, quartz), and can also reduce the leakage of condensed aerosol during heating, thus reducing contamination of the microwave heating module 1.

[0026] like Figure 2 , Figure 3 and Figure 10 As shown, in some embodiments, the housing unit 10 may include a housing, a separator 13, and a suction nozzle structure 15. The housing defines the outer contour of the microwave heating module 1 and may be a generally flat elliptical columnar structure, which internally defines a receiving cavity 111, a first receiving cavity 112, a second receiving cavity 113, a window 114, and a heating cavity 115.

[0027] The window 114 connects the heating cavity 115 to the outside. The receiving cavity 111 is used to receive at least a portion of the microwave heating unit 20, which is connected to the heating cavity 115 through the window 114, such that the microwave heating unit 20 and the heating cavity 115 are located on opposite sides of the window 114. The aerosol generating product 2 located in the heating cavity 115 can be heated by the microwave heating unit 20 through the window 114 to generate aerosol. The first receiving cavity 112 and the second receiving cavity 113 can be connected to the heating cavity 115 respectively. The first receiving cavity 112 can receive the unheated aerosol generating product 2, and the second receiving cavity 113 can receive the heated aerosol generating product 2.

[0028] See also Figures 5 to 8 The aerosol generating article 2, along its length, can sequentially traverse from the first receiving cavity 112 through the heating cavity 115 to the second receiving cavity 113. The region of the aerosol generating article 2 located within the heating cavity 115 can be heated by the microwave heating unit 20 within the receiving cavity 111 to generate aerosol. The aerosol guiding unit 50 is disposed within the heating cavity 115 to directionally rectify the airflow within the heating cavity 115, improving the aerosol transport efficiency within the heating cavity 115. The suction nozzle structure 15 allows the user to suction out the aerosol within the heating cavity 115.

[0029] It should be understood that "traversal" can be interpreted as the longitudinally elongated sheet-like aerosol generating product 2 being divided into multiple regions along its length, with each region generally and sequentially passing through the heating chamber 115.

[0030] Of course, the traversal heating strategy for the aerosol-generating article 2 can be flexibly controlled by the electronic control mechanism of the aerosol generating device it is equipped with. For example, it can be controlled so that each region of the aerosol-generating article 2 is uniformly heated when passing through the heating chamber 115. Another example is controlling the length of each movement of the aerosol-generating article 2, so that each region is traversed at fixed or non-fixed intervals, that is, each region is heated regularly or irregularly in an alternating manner. No specific limitations are made here.

[0031] It's important to understand that microwave heating modules in related technologies typically employ a central heating element inserted into a cylindrical aerosol-generating product, or a peripheral heating element surrounding the cylindrical aerosol-generating product, to heat it. This method generally requires insulation measures similar to traditional heating technologies (resistive, electromagnetic, etc.) after the initial heating of the aerosol-generating product to prevent excessively low temperatures that could lead to the generation of harmful substances in the un-aerosolized portions of the product, negatively impacting the user experience. Therefore, for this type of microwave heating module and its associated aerosol-generating product, users must complete the aerosol release within a fixed timeframe (usually several minutes) after initial use, and cannot release aerosols as needed over longer periods (e.g., several hours).

[0032] By sequentially passing each region of the aerosol generating product 2 along its length through the heating chamber 115, the microwave heating unit 20 can heat only a single region of the aerosol generating product 2 at a time, allowing the user to utilize the aerosol generated in that region without worrying about heating other regions of the aerosol generating product 2, thus avoiding aerosol waste. Simultaneously, this arrangement eliminates the need for heat preservation after the initial heating, preventing the generation of harmful substances in other regions of the aerosol generating product 2 due to low temperatures. Furthermore, the heating of each region of the entire aerosol generating product 2 can be flexibly controlled according to the user's needs, eliminating the need to utilize all the aerosol generated by the entire aerosol generating product 2 within a fixed timeframe, thus meeting the user's requirement for on-demand release and immediate shutdown of aerosols over extended periods.

[0033] It is important to understand that microwave heating technology offers advantages such as rapid heating, spontaneous substrate heating, and no thermal inertia, making it beneficial for users with high-volume usage requirements and / or on-demand operation needs. For users with high-volume usage requirements, the corresponding aerosol-generating product 2 needs to have a larger volume and mass.

[0034] This application heats a single area of ​​the aerosol generating product 2 using a heating chamber 115. This single heating process releases all the aerosols generated within a fixed area of ​​the aerosol generating product 2, and can be combined with microwave heating technology to further meet users' needs for large-capacity applications. Furthermore, by providing a first receiving chamber 112 and a second receiving chamber 113, this application can also increase the collection capacity of the aerosol generating product 2, thereby simultaneously meeting the needs of users requiring large-capacity applications.

[0035] like Figures 4 to 10As shown, the separator 13 is disposed within the heating cavity 115 and covers the window 114, serving to separate the receiving cavity 111 and the heating cavity 115. During use, the separator 13 can be positioned between the microwave heating unit 20 within the receiving cavity 111 and the aerosol generating product 2 within the heating cavity 115, to prevent aerosols generated during heating from contaminating the microwave heating unit 20 within the receiving cavity 111 through the window 114, thereby ensuring the service life of the microwave heating unit 20 and improving the aerosol output rate within the heating cavity 115.

[0036] like Figures 5 to 9 As shown, in some embodiments, the receiving cavity 111 and the heating cavity 115 may extend along the width direction of the housing unit 10. The first receiving cavity 112 and the second receiving cavity 113 may each be a cylindrical space with arc-shaped sidewalls, located at the two ends of the elliptical cylindrical housing unit 10 along its length, and on opposite sides of the receiving cavity 111 and the heating cavity 115 along the length of the housing unit 10. This arrangement improves the space utilization rate inside the housing unit 10. The heating cavity 115 may have a long and narrow channel-type chamber structure to facilitate directional rectification by the airflow guiding unit 30 during suction, thereby improving the aerosol output rate.

[0037] It should be understood that in some embodiments, the unheated portion and the heated portion of the aerosol-generated article 2 can be respectively rolled up in the first accommodating cavity 112 and the second accommodating cavity 113. The unrolled portion between them is exposed on the traversal path.

[0038] The traversal path can be understood as the path taken by each region of the aerosol-generated product 2 along its length direction from the first accommodating cavity 112 through the heating cavity 115 to the second accommodating cavity 113.

[0039] Along the traversal path, there may be a portion of the aerosol-generated product 2 that is not within the heating chamber 115, nor is it rolled up in the first accommodating chamber 112 or the second accommodating chamber 113, but is in a position that has detached from the roll and is ready to enter the heating chamber 115 or has already left the heating chamber 115.

[0040] By placing the first accommodating cavity 112 and the second accommodating cavity 113 on opposite sides of the heating cavity 115, the length of the aerosol generating product 2 that is not in the heating cavity 115 along the traversal path can be shortened, thereby reducing the contamination of the unheated aerosol generating product 2 and also reducing the possibility of the heated aerosol generating product 2 contaminating the equipment or other aerosol generating product 2 areas.

[0041] In other embodiments, the first accommodating cavity 112 and the second accommodating cavity 113 may also be located on the same side of the receiving cavity 111 and / or the heating cavity 115 along the width or length direction of the housing unit 10, or disposed on the same side or opposite sides of the receiving cavity 111 and / or the heating cavity 115 along the height direction of the housing unit 10. They can be flexibly arranged within the housing unit 10 according to actual needs; there are too many potential embodiments to list them all here.

[0042] In some other embodiments, the housing unit 10 may define only the heating cavity 115 and two receiving cavities. The microwave heating unit 20 may be entirely located outside the housing, and it and the heating cavity 115 may be located on opposite sides of the separator 13.

[0043] In other embodiments, the housing unit 10 may also be cylindrical, polygonal columnar, irregular columnar, hemispherical, spherical, polygonal body-shaped, irregular, or other shapes.

[0044] like Figure 2 and Figure 3 As shown, in some embodiments, the housing includes a main body 11 and a cover 12. The main body 11 is a hollow shell with one end open, defining a receiving cavity 111 and a window 114. The cover 12 seals the through end of the main body 11, and together they define a relatively sealed first receiving cavity 112, a second receiving cavity 113, and a heating cavity 115. By providing the main body 11 and the cover 12, the production and assembly efficiency of the microwave heating module 1 can be improved.

[0045] It should be understood that the main body 11 and the cover 12 can be detachably or non-detachably assembled with each other through various methods such as snap-fit ​​connection, bolt connection, threaded connection, interference fit, welding, glue connection, etc., without specific limitations.

[0046] In some embodiments, the end of the main body 11 away from the cover 12 defines a connection port 116. The receiving cavity 111 can communicate with the outside through the connection port 116. During the manufacturing process, the microwave heating unit 20 can be assembled into the receiving cavity 111 through the connection port 116, and the connection port 116 can be closed to form an embedded fit between the microwave heating unit 20 and the housing unit 10. This arrangement facilitates the assembly of the microwave heating unit 20 and improves the relative sealing of the receiving cavity 111.

[0047] Specifically, the main body 11 may include a side wall 1101, a bottom wall 1102, and a spacer 1103. The side wall 1101 is cylindrical with both ends open, the bottom wall 1102 covers one end of the side wall 1101, and a cover 12 is used to cover the other end of the side wall 1101. The connection port 116 extends through the bottom wall 1102 along its thickness direction.

[0048] The partition 1103 is erected on the bottom wall 1102 and located inside the side wall 1101, and is used to divide the space defined by the side wall 1101, the bottom wall 1102 and the cover 12 into a first accommodating cavity 112, a second accommodating cavity 113, a receiving cavity 111 and a heating cavity 115.

[0049] Specifically, one end of the partition 1103 is open, and the open end is fastened to the bottom wall 1102 at the connection port 116, defining the receiving cavity 111. The side of the partition 1103 near the heating cavity 115 also defines the window 114. The separator 13 can be attached to the partition 1103 to cover the window 114.

[0050] In some other embodiments, the spacer 1103 may also be a cylindrical structure with open ends, and the spacer 1103 can be closed off from the end of the connection port 116 by the cover 12.

[0051] In other embodiments, the connection port 116 can also be adjusted according to the relative position of the receiving cavity 111, and can be located at other positions on the housing such as the side wall 1101 or the cover 12. The specific structure of the spacer 1103 can also be adjusted accordingly based on the distribution changes of the receiving cavity 111, the first receiving cavity 112, the second receiving cavity 113, and the heating cavity 115. There are many potential embodiments, which will not be elaborated on here.

[0052] It should be understood that the side walls 1101, bottom walls 1102, and spacers 1103 of the main body 11 can be assembled and fixed by means of glue connection, welding, integral molding, bolt connection, snap-fit ​​connection, etc., and no specific limitation is made here.

[0053] like Figure 1 As shown, in some embodiments, the outer periphery of the cover 12 may be larger than the outer periphery of the main body 11 perpendicular to the axial direction, that is, the outer periphery of the cover 12 extends beyond the main body 11. When the microwave heating module 1 is assembled to the aerosol generating device, the outer periphery of the cover 12 can be adapted to the outer shell of the aerosol generating device (not shown in the figure), and the two together define the outer contour of the aerosol generating device.

[0054] Furthermore, the cover 12 may include a substrate and a metal layer disposed on the substrate.

[0055] It should be understood that during use, the electromagnetic energy released by the microwave heating unit 20 of the microwave heating module 1 can have harmful effects on surrounding electronic equipment and the human body. This application achieves metallization of the cover 12 by laying a metal layer on it. When the microwave heating module 1 is assembled into the housing of the aerosol generating device, the cover 12, together with the metal housing, forms an electromagnetic shielding space, improving the shielding effect and effectively preventing the leakage of electromagnetic energy generated by the microwave heating unit 20. Figure 12 and Figure 13 As shown, during use, the electric field strength of the metallized cover 12 is much smaller than that of the cover 12 without a metal layer.

[0056] It should be understood that the metal layer can be applied to the substrate through processes such as spraying to achieve the metallization of the cover 12, and no specific limitation is made here.

[0057] In some other embodiments, the cover 12 may also be made of metal. Of course, both the cover 12 and the main body 11 may be made of metal, or the outer surface may be covered with a metal layer, together forming a barrier for the electromagnetic shielding space.

[0058] Alternatively, both the cover 12 and the main body 11 can be made of various wave-transparent materials and enclosed within the outer shell of the aerosol generating device. In this embodiment, the electromagnetic shielding space can be defined by setting the outer shell of the aerosol generating device as a metal structure or by covering its surface with a metal layer.

[0059] like Figures 2 to 4 As shown, in some embodiments, the separator 13 may be in the form of a thin sheet, which is attached to the partition 1103 around the perimeter by means of adhesive to cover the window 114 and ensure the separation effect.

[0060] It should be understood that the aerosols released by the aerosol generating product 2 can easily diffuse and adhere to the surface of the microwave heating unit 20. After prolonged use, this can easily lead to the failure of the microwave heating unit 20 and affect the service life of the microwave heating module 1.

[0061] By setting the separator 13, the leakage of aerosol from the heating cavity 115 into the receiving cavity 111 can be effectively prevented, avoiding contamination of the microwave heating unit 20. This also avoids potential heating failure of the microwave heating unit 20 after long-term use, thus improving the consistency of the user's long-term experience. Furthermore, it can also improve the relative sealing of the receiving space of the aerosol-generating product 2, providing an airtight basis for the design of the airflow guiding unit 30 within the heating cavity 115. This facilitates the efficient removal of aerosol from the heating cavity 115, thereby helping to maintain the cleanliness of the housing unit 10 and preventing the spread of aerosol within the housing unit 10, which could contaminate the housing.

[0062] Specifically, the window 114 can be in various shapes such as rectangle, ellipse, circle, polygon, or irregular shape. The separator 13 can be set to various shapes such as rectangle, ellipse, circle, polygon, or irregular shape, or it can be set to a different shape from the window 114.

[0063] In some other embodiments, the separator 13 may also be in the form of a thin film. The film-shaped separator 13 may have a thinner thickness to improve the absorption rate of electromagnetic energy by the aerosol-generating article 2, reduce the energy consumption required for heating the aerosol-generating article 2 per cycle, and also reduce costs.

[0064] In some embodiments, the separator 13 may be made of a wave-transparent material. Further, it may be made of a lossless or low-loss material that has high-temperature resistance, thermal conductivity, and the ability to transmit infrared light waves.

[0065] The separator 13 can be made of at least one of ceramics (alumina ceramics, silicon nitride ceramics, boron nitride ceramics, etc.), polyimide (PI), mica, quartz glass, polyetheretherketone (PEEK), liquid crystal polymer (LCP), and polytetrafluoroethylene (PTFE). For example, the separator 13 can be a polyimide film, a ceramic sheet, or a mica sheet, etc., and no specific limitation is made here.

[0066] By selecting materials such as ceramic materials that have high temperature resistance and infrared light wave penetration properties to make the separator 13, the service life of the separator 13 can be improved, enabling long-term operation in special working environments such as high temperature and infrared light wave radiation. This avoids problems such as aging and damage of the separator 13 due to excessive heating temperature of the microwave heating unit 20, and achieves the reliability of long-term suction for users with large number of mouths.

[0067] When the separator 13 is made of low-loss, high-temperature resistant polyimide film, polyetheretherketone (PEEK), or mica material, the cost can be further reduced. At the same time, the thinner polyimide film and mica sheet can improve the absorption rate of electromagnetic energy by the aerosol-generating product 2 and reduce the energy consumption required for heating the aerosol-generating product 2 per cycle.

[0068] In some embodiments, the main body 11 and the cover 12 may be provided with mounting holes or mounting grooves, respectively. At least a portion of the periphery of the partition 13 is confined within the mounting hole or mounting groove to improve the positioning effect of the partition 13 within the housing and ensure the reliability of the closing of the window 114.

[0069] Specifically, such as Figure 2 , Figure 3 and Figure 10 As shown, an assembly hole 118 is defined on the bottom wall 1102 of the main body 11. (See also...) Figure 4 The cover 12 has a recessed mounting groove 122 on the side facing the main body 11. This design further improves the assembly efficiency of the housing unit 10. During assembly, the separator 13 can be inserted into the mounting hole 118 first, and then attached to the spacer 1103. When the cover 12 is then closed onto the through end of the main body 11, the other end of the separator 13 is correspondingly confined within the mounting groove 122.

[0070] Furthermore, such as Figure 3 As shown, one side of the mounting hole 118 can be connected to the connection port 116 so that the partition 13 can fit tightly against the outer wall of the partition portion 1103, ensuring the covering effect of the window 114.

[0071] Of course, in some other embodiments, the mounting hole 118 on the body 11 may also be configured as a non-through groove.

[0072] In some other embodiments, the partition 13 may also be filled into the window 114 or attached to the inner wall of the partition portion 1103 to cover the window 114 from the receiving cavity 111 side.

[0073] In some other embodiments, the partition 1103 may also be provided with a mounting groove, and the window 114 can be covered by inserting the partition 13 into the mounting groove. Alternatively, the partition 13 may also be fitted onto the window 114 by other means such as bolt connection, integral molding, or snap-fit ​​connection.

[0074] like Figures 2 to 4 As shown, in some embodiments, the suction nozzle structure 15 is disposed on the side of the cover 12 opposite to the main body 11 and defines an air outlet channel 150. The cover 12 has an air outlet 121 at the position corresponding to the suction nozzle structure 15. The air outlet 121 can communicate with both the air outlet channel 150 and the heating chamber 115. An air guide hole 117 is also defined on the bottom wall 1102 of the main body 11, corresponding to the heating chamber 115, to communicate with it. During the user's suction process, the airflow can enter the heating chamber 115 through the air guide hole 117, mix with the aerosol in the heating chamber 115, and then carry the aerosol out sequentially through the air outlet 121 and the air outlet channel 150.

[0075] Of course, in embodiments where the housing unit 10 is entirely enclosed within the housing of the aerosol generating device, the nozzle structure 15 can also be disposed on the housing of the aerosol generating device.

[0076] In other embodiments, the vent 117 may also be located at other locations on the wall of the heating chamber 115. For example, it may be located on the side wall 1101 that defines the heating chamber 115.

[0077] It should be understood that the suction nozzle structure 15 can be detachably or non-detachably assembled onto the cover 12 through threaded connection, snap-fit ​​connection, bolt connection, integral molding, interference fit, etc., without specific limitations.

[0078] For example Figure 2 and Figure 3 As shown, in some embodiments, the microwave heating unit 20 may include an outer conductor structure 21, an inner conductor structure 22, and an electrical connection structure 23. The outer conductor structure 21 defines a cavity 211, and the inner conductor structure 22 is at least partially spaced within the cavity 211 to radiate electromagnetic energy after microwave feeding, forming an energy field with the outer conductor structure 21. The electrical connection structure 23 is disposed between the outer conductor structure 21 and the inner conductor structure 22, and makes ohmic contact with both.

[0079] Specifically, one end of the outer conductor structure 21 is open, allowing the cavity 211 to connect to the outside through this open end. The electrical connection structure 23 is generally cap-shaped and fits over the open end of the outer conductor structure 21, thus relatively sealing the cavity 211. The inner conductor structure 22 can be assembled onto the electrical connection structure 23. When the electrical connection structure 23 fits over the open end of the outer conductor structure 21, the inner conductor structure 22 can be assembled into the outer conductor structure 21 from its open end, together with the outer conductor structure 21, forming a complete heating resonant cavity.

[0080] This arrangement further improves assembly efficiency. During assembly, the inner conductor structure 22 can be assembled onto the electrical connection structure 23 first, and then the assembly of the two can be assembled onto the outer conductor structure 21 from the through end. Furthermore, the assembled microwave heating unit 20 can be assembled onto the housing from the connection port 116 of the main body 11.

[0081] In some embodiments, the electrical connection structure 23 may be configured as a cover with a boss, so as to improve the relative sealing effect of the cavity 211 and reduce microwave leakage by the close fit between the boss and the through end of the outer conductor structure 21.

[0082] In some embodiments, when the microwave heating unit 20 is assembled to the housing unit 10, the through end of the outer conductor structure 21 can be located at the connection port 116, so that the electrical connection structure 23 is exposed outside the housing unit 10, so as to facilitate the disassembly, assembly, maintenance, etc. of the components.

[0083] Of course, the location of the through end of the outer conductor structure 21 can also ensure that when the microwave heating unit 20 is assembled into the housing unit 10, at least part of the electrical connection structure 23 is located inside the housing unit 10.

[0084] It should be understood that the assembly between the electrical connection structure 23 and the outer conductor structure 21 and the inner conductor structure 22 can be detachably or non-detachably connected by means of bolt connection, welding, snap connection, interference fit, threaded connection, glue connection, integral molding, etc., without specific limitations.

[0085] It should be understood that the outer conductor structure 21, the inner conductor structure 22, and the electrical connection structure 23 can all be formed using metallic materials or other materials with high conductivity. For example, they can be made of materials such as gold, silver, copper, aluminum, iron, gold-containing alloys, aluminum-containing alloys, copper-containing alloys, iron-containing alloys, or stainless steel. Alternatively, they can be formed by applying a metallic coating to the outer surface of a substrate, such as gold-plated stainless steel. No specific limitations are made here.

[0086] In some embodiments, the outer conductor structure 21 further defines an opening 212 located on one side of the outer conductor structure 21, which connects the cavity 211 to the outside. See also... Figure 4 When the microwave heating unit 20 is assembled into the housing unit 10, at least a portion of the outer conductor structure 21 is housed within the housing cavity 111, and a portion of the outer conductor structure 21 may be located within the window 114, such that the opening 212 may overlap within the window 114. The heating cavity 115 and the cavity 211 are connected through the opening 212 and the window 114, and the separator 13 covers the window 114 and the opening 212. A portion of the inner conductor structure 22 is located within the opening 212 and the window 114, and is exposed through the opening 212 and the window 114, so as to fit snugly against the separator 13.

[0087] The opening 212 can be any shape, such as circular, elliptical, rectangular, polygonal, or irregular. Its shape can be the same as or different from that of the window 114; no specific limitation is made here.

[0088] This configuration improves the heating efficiency of the energy field on the separator 13, thereby increasing the heating efficiency of the aerosol-generating product 2 region located within the heating chamber 115 and reducing heating of unnecessary areas. It also ensures that the inner conductor radiates electromagnetic energy.

[0089] In some embodiments, the outer conductor structure 21 is further defined with an air inlet 213. When the microwave heating unit 20 is assembled to the housing unit 10, the air inlet 213 can communicate with the air guide hole 117 on the main body 11.

[0090] In some other embodiments, the electrical connection structure 23 may also be provided with a corresponding air inlet 213. Alternatively, the air guide hole 117 may be directly connected to the outside.

[0091] For example Figures 2 to 4As shown, in some embodiments, the inner conductor structure 22 is longitudinally elongated and may include a connecting portion 221 and a microwave radiating portion 222 connected end to end. The connecting portion 221 is at least partially disposed within the cavity 211, with one end fitted to the electrical connection structure 23 and the other end connected to the microwave radiating portion 222. The microwave radiating portion 222 and the aerosol generating product 2 within the heating cavity 115 are located on opposite sides of the separator 13. At least a portion of the microwave radiating portion 222 extends within the opening 212 and the window 114 and is in contact with the separator 13.

[0092] This setup can further improve the heating efficiency of aerosol-generated product 2 and reduce the heating effect on unnecessary areas.

[0093] It should be noted that the opening 212 is a visible radiation window, designed to restrict the radiation of electromagnetic energy outside the cavity 211. The vast majority of the electromagnetic energy can be absorbed by the aerosol-generating product 2.

[0094] By designing the shape and size of the opening 212, the shape and size of the heated area of ​​the aerosol-generating product 2 can be accurately controlled, thus effectively controlling the carbonization area of ​​the aerosol-generating product 2. Controlling the carbonization area of ​​the aerosol-generating product 2 effectively controls the amount of aerosol released during a single heating cycle and improves the uniformity of heating in different areas of the longitudinally elongated aerosol-generating product 2, preventing localized overheating and scorching.

[0095] The shape and size of the window 114 and the opening 212 can be flexibly set according to the area that needs to be heated in the aerosol-generated product 2, and no specific limitation is made here.

[0096] Figure 14 This application shows Figure 1 The illustrated embodiment shows the volume loss density distribution of the aerosol-generating product 2 when the microwave heating module 1 heats a certain area of ​​the aerosol-generating product 2. According to this figure, the configuration of this application can effectively prevent areas of the aerosol-generating product 2 outside the heating chamber 115 from being heated by heating a small area of ​​the aerosol-generating product 2 in a traversing manner. This ensures that each area of ​​the aerosol-generating product 2 is uniformly heated within the heating chamber 115 during the traversal process. Simultaneously, through… Figure 14 It can be clearly seen that the boundary between the heated area and the unheated area of ​​the aerosol-generated product 2 is obvious, and the outline of the heated area is clear. Therefore, it can be seen that the shape and size design of the window 114 and the opening 212 can effectively control the area of ​​carbonized area of ​​the aerosol-generated product 2 each time it is heated, thereby improving the uniformity of the heated area along the length direction and the consistency of the heating effect, and avoiding local overheating and scorching.

[0097] Figure 15 This application shows Figure 1 The S-parameters (scattering parameters) of the aerosol-generating product 2 are shown in the embodiment where the microwave heating module 1 heats a certain area of ​​the aerosol-generating product 2. As can be seen from the figure, the arrangement of this application ensures good impedance matching. Most of the microwave energy within the microwave heating unit 20 can be absorbed by the area of ​​the aerosol-generating product 2 located within the heating cavity 115, minimizing reflection and loss.

[0098] Continue reading Figures 2 to 4 In some embodiments, the connecting portion 221 is generally L-shaped, comprising a first portion 2211 and a second portion 2212 that are perpendicular to each other. The first portion 2211 can be considered the long side of the L-shape, extending axially along the cavity 211 and the housing, with one end connected to the electrical connection structure 23 and the other end connected to one end of the second portion 2212. The second portion 2212 can be considered the short side of the L-shape, extending axially perpendicular to the cavity 211 and the housing, with one end connected to the first portion 2211 and the other end extending to the opening 212 to connect with the microwave radiating portion 222, so that the microwave radiating portion 222 is located within the opening 212.

[0099] In some other embodiments, the end of the second portion 2212 may also be connected to the middle position of the first portion 2211, so that the connection portion 221 is generally T-shaped.

[0100] In some other embodiments, the angle between the extension directions of the second portion 2212 and the first portion 2211 may be less than 90°, so that the inner conductor structure 22 is approximately Z-shaped.

[0101] In some other embodiments, the connecting portion 221 may also be configured as a curved shape, specifically as a C-shape, S-shape, irregular shape or other shapes.

[0102] In some other embodiments, the first portion 2211 may also be curved or bent.

[0103] In some embodiments, the microwave radiating portion 222 may be in the shape of an elongated cylindrical rod, extending within the opening 212 and window 114 in a direction perpendicular to the movement of the aerosol generating article 2, with the extension direction parallel to the extension direction of the first portion 2211. That is, it extends along an axis parallel to the cavity 211 and the housing, from one end of the opening 212 away from the through end of the outer conductor structure 21 to the end near the through end of the outer conductor structure 21.

[0104] One end of the microwave radiating section 222, away from the through end of the outer conductor structure 21, is connected to the end of the second part 2212, and its extension direction is perpendicular to the extension direction of the second part 2212. Thus, the structure after the microwave radiating section 222 and the second part 2212 are connected is approximately L-shaped, and the inner conductor structure 22 is approximately n-shaped with a bend.

[0105] Along the moving direction of the aerosol-generated article 2, the microwave radiating part 222 is approximately located at the midline of the window 114 and the opening 212, so as to facilitate uniform heating of the separator 13.

[0106] This configuration allows the energy field to be positioned closer to the heating chamber 115, improving the heating efficiency of the energy field on the separator 13 and reducing heating of unnecessary areas.

[0107] In other embodiments, the microwave radiating part 222 may also be in the form of a rectangular rod, an elliptical rod, a polygonal rod, a column of various shapes, a sheet perpendicular to the separator 13, or other shapes.

[0108] In some other embodiments, the extending direction of the microwave radiating part 222 may also be at an angle to the extending direction of the first part 2211.

[0109] In some other embodiments, the angle between the extending direction of the microwave radiating part 222 and the extending direction of the second part 2212 may be less than 90°.

[0110] In some other embodiments, the end of the second portion 2212 away from the first portion 2211 may also be connected to the end of the microwave radiating portion 222 near the through end of the outer conductor structure 21.

[0111] In some other embodiments, there may also be a certain gap between the microwave radiating part 222 and the separator 13.

[0112] In some embodiments, the microwave heating unit 20 may further include a waterproof structure (not shown in the figure). The waterproof structure may be disposed inside the cavity 211 and located between the outer conductor structure 21 and the inner conductor structure 22, for keeping the cavity 211 dry in water-exposed environments such as rain, thereby ensuring the normal operation of the microwave heating unit 20.

[0113] Specifically, the end face of the waterproof structure away from the through end of the outer conductor structure 21 can be set as an inclined end face to improve the waterproof effect.

[0114] It should be understood that the waterproof structure can be made of high-temperature resistant materials with low loss and low dielectric constant, such as Teflon, etc., without specific limitations.

[0115] like Figure 2 and Figure 3As shown, in some embodiments, the media traversal unit 40 may include a first reel 41, a second reel 42, and at least one guide. See also... Figure 8 A first spool 41 is disposed within the first receiving cavity 112 to receive the unheated portion of the aerosol-generated product 2. A second spool 42 is disposed within the second receiving cavity 113 to receive the heated portion of the aerosol-generated product 2. The guide is used to press the portion of the aerosol-generated product 2 located within the heating cavity 115 towards the window 114, so that the aerosol-generated product 2 fits as closely as possible to the separator 13.

[0116] This application, by setting up a first reel 41 and a second reel 42, allows the unheated and heated portions of the aerosol-generated product 2 to be wound onto the first reel 41 and the second reel 42 respectively, and stored in the first accommodating cavity 112 and the second accommodating cavity 113 respectively, thereby improving the utilization rate of the internal chambers of the housing unit 10. This arrangement can further improve the volume and weight of the aerosol-generated product 2, meeting the needs of users with large-volume requirements.

[0117] Meanwhile, the winding arrangement can be similar to that of a magnetic tape playback, facilitating the movement of the aerosol-generating product 2 along the traversal path. The winding storage method also reduces the exposed area of ​​both the unheated and heated portions of the aerosol-generating product 2, further mitigating aerosol pollution.

[0118] It is important to understand that microwave heating technology is highly sensitive to the distance between the aerosol generating product 2 and the microwave heating unit 20. When the distance is close, the electric field strength within the aerosol generating product 2 is higher, resulting in a faster heating rate. Conversely, when the distance is greater, the electric field strength within the aerosol generating product 2 is lower, leading to a slower heating rate. By controlling the distance between the two, the consistency of heating from one end to the other can be effectively improved.

[0119] This application, by providing at least one guide member, ensures that the area of ​​the aerosol-generating product 2 within the heating cavity 115 is well pressed against the separator 13, effectively maintaining the distance between the aerosol-generating product 2 and the microwave heating unit 20. It also reduces problems such as tilting and wrinkling that may occur during the movement of the aerosol-generating product 2 along the traversal path. This design ensures better microwave matching, guarantees the stability and consistency of the microwave heating effect, and achieves a more stable and superior suction experience.

[0120] In some other embodiments, the medium traversal unit 40 may not have the first reel 41 and / or the second reel 42, or the first reel 41 and / or the second reel 42 may be disposed outside the housing unit 10. The housing unit 10 may also not have the first accommodating cavity 112 and / or the second accommodating cavity 113, or the first accommodating cavity 112 and / or the second accommodating cavity 113 may be disposed outside the housing unit 10. In such embodiments, holes for the aerosol generating article 2 to pass through can be provided at corresponding positions on the main body 11 of the housing unit 10, allowing the aerosol generating article 2 to enter the housing unit 10 through the holes, be heated by the heating chamber 115, and then exit the housing unit 10 through another hole.

[0121] In some other embodiments, the medium traversal unit 40 may not have a guide member. By controlling the position of the first reel 41 and / or the second reel 42, a certain angle is formed between the portion of the aerosol-generating product 2 passing through the heating chamber 115 and the other portions of the aerosol-generating product 2. Furthermore, the tensioning and restraining effect of the first reel 41 and the second reel 42 on the aerosol-generating product 2 allows the portion of the aerosol-generating product 2 located within the heating chamber 115 to be pressed onto the separator 13 without external pressure.

[0122] It should be understood that the main body 11, cover 12, first roll 41, second roll 42, and guide can be made of materials such as polyphenylene sulfone resin (PPSU), Teflon, PEEK, acrylic, and various composite wave-transparent materials, without specific limitations.

[0123] like Figures 5 to 8 As shown, in some embodiments, the first spool 41 and the second spool 42 are respectively arranged parallel to the axis of the housing, and are approximately located at the central axis of the first accommodating cavity 112 and the second accommodating cavity 113, so as to improve the utilization of space. The longitudinally elongated sheet-like aerosol generating product 2 has its two ends fixed to the first spool 41 and the second spool 42 respectively, so as to ensure the overall tension and stability of the aerosol generating product 2 during the traversal process.

[0124] Specifically, the first scroll 41 and the second scroll 42 are both cylindrical. (See also...) Figure 3 and Figure 9 The main body 11 and the cover 12 are recessed at the positions corresponding to the first scroll 41 to form limiting grooves 16, so as to limit the two ends of the first scroll 41 within the limiting grooves 16, thereby limiting the first scroll 41 within the first accommodating cavity 112.

[0125] The second spool 42 includes a shaft body 421 and a drive unit 422. The shaft body 421 is cylindrical and is disposed within the second accommodating cavity 113. The drive unit 422 is located at one end of the shaft body 421 and outside the housing unit 10, serving as an external drive mechanism to rotate the shaft body 421. The main body 11 and the cover 12 are respectively provided with limiting grooves 16 at positions corresponding to the shaft body 421 to limit the rotation of the shaft body 421 within the second accommodating cavity 113. The main body 11 also has a through hole 119 penetrating through the wall of the limiting groove 16 corresponding to the second spool 42, through which the second spool 42 passes, allowing the drive unit 422 to extend outside the housing unit 10 and connect to an external drive mechanism.

[0126] It should be understood that the drive unit 422 can be implemented using structures such as gears, couplings, and flanges. Its external drive mechanism can be an electric drive mechanism such as a motor, turbine, or motor housed within the housing of the aerosol generating device. Alternatively, it can be implemented using a manually operated knob exposed outside the housing of the aerosol generating device, operated manually by the user. No specific limitations are specified here.

[0127] By providing a drive unit 422 on the second spool 42, when the second spool 42 is driven to wind up the heated aerosol-generated product 2, the aerosol-generated product 2 can be moved synchronously along the traversal path towards the second spool 42, and the first spool 41 can release a section of the aerosol-generated product 2 accordingly. Furthermore, the area of ​​the aerosol-generated product 2 located within the heating chamber 115 can be moved out of the heating chamber, and the next area can simultaneously enter the heating chamber 115.

[0128] In other words, this configuration further enhances the flexibility and ease with which users can control the aerosol generating product 2 to traverse each region along its length. During use, users can flexibly control the time interval between different regions of the aerosol generating product 2 by controlling the drive mechanism within the aerosol generating device. The aerosol generating product 2 does not need to complete aerosol release within a fixed time, thus meeting the user's need for on-demand release and flexible start-stop functionality. Simultaneously, this traversal method ensures uniform heating of each region, thereby guaranteeing consistent aerosol generation and a consistent user experience.

[0129] In some other embodiments, the first reel 41 may also include a shaft and a drive unit. By controlling the drive mechanism, the first reel 41 and the second reel 42 are driven to rotate synchronously, so that while the first reel 41 releases the aerosol-generated product 2 at a fixed rate, the second reel 42 simultaneously winds up the aerosol-generated product 2 at the same rate.

[0130] In some other embodiments, the number of second spools 42 may be at least two. By arranging the two second spools 42 parallel and spaced apart, and controlling the gap between them, the aerosol-generating article 2 can be sandwiched between them. When it is necessary to control the movement of the aerosol-generating article 2, by driving the two second spools 42 to rotate in opposite directions, the two second spools 42 simultaneously provide frictional forces in the same direction to the aerosol-generating article 2, thereby driving the movement of the aerosol-generating article 2. Similarly, the number of first spools 41 may also be at least two, which will not be elaborated further here.

[0131] It is important to understand that the scroll (abbreviated as first scroll 41 or second scroll 42) is rotatably disposed within the receiving cavity (abbreviated as first receiving cavity 112 or second receiving cavity 113), which can be achieved by configuring the scroll to include a support structure and a rotating structure. Specifically, the support structure can be fixed axially within the receiving cavity, the rotating structure can be rotatably fitted onto the support structure, and the aerosol-generating product 2 can be rolled onto the rotating structure. By rotatably disposing the rotating structure relative to the receiving cavity and the support structure, the aerosol-generating product 2 can be stored and released. Alternatively, a rotating connection structure such as a bearing can be provided between the scroll and the cavity wall of the receiving cavity to achieve rotatable placement of the scroll within the receiving cavity. Alternatively, a limiting structure such as a groove or protrusion can be provided correspondingly within the cavity wall of the receiving cavity to create a stable rotational space between the two ends of the scroll, allowing the scroll to slide directly in contact with the cavity wall of the receiving cavity, thus achieving rotatable placement of the scroll. There are many existing technologies that can achieve this, which will not be elaborated on here.

[0132] In some other embodiments, the first reel 41 and / or the second reel 42 may also be configured as a flat rectangular plate, an elliptical column, a polygonal column, an irregular column, or other shapes.

[0133] exist Figure 8 In the illustrated embodiment, there are two guide members. They are now defined as the first guide member 43 and the second guide member 44, respectively. The first guide member 43 and the second guide member 44 are spaced apart on opposite sides within the heating chamber 115 along the traversal path of the aerosol-generating article 2.

[0134] By setting the number of guide members to two and placing them at intervals on opposite sides of the heating chamber 115, the pressing effect on the aerosol-generated product 2 can be further improved, while the problems of tilting and wrinkling that occur during the movement of the aerosol-generated product 2 along the traversal path can be further reduced.

[0135] like Figure 16 , Figure 17 , Figure 18 , Figure 19 As shown, combined with Figure 14The volume loss density distribution shown clearly indicates that, as the gap between the aerosol-generating product 2 and the separator 13 gradually increases, or problems such as uneven adhesion to the separator 13 occur, the volume loss density of the aerosol-generating product 2 is significantly reduced compared to the embodiment with the first guide 43 and the second guide 44 constructed in this application. Therefore, the provision of the first guide 43 and the second guide 44 can further improve the heating effect of the microwave heating unit 20 on the aerosol-generating product 2, improve the utilization rate of microwave energy, and thus improve the user experience. At the same time, it can also prevent differences in the adhesion between each area of ​​the aerosol-generating product 2 and the separator 13 during the process, ensuring the consistency of the heating effect in each area.

[0136] according to Figure 20 It can be seen that, compared to the aerosol-generating product 2 which is tightly fitted to the separator 13, the S-parameters of the aerosol-generating product 2 are significantly worse when it is not tightly fitted to the separator 13. Therefore, the provision of the first guide 43 and the second guide 44 can further ensure the impedance matching effect. At the same time, it can also prevent differences in the degree of fit between each region of the aerosol-generating product 2 and the separator 13 during the traversal process, ensuring the consistency of the impedance matching effect.

[0137] In some other embodiments, the medium traversal unit 40 may also include two or more guide members. By providing at least one or at least two guide members on each of the opposite sides of the heating chamber 115, the pressing effect on the aerosol-generated article 2 can be further improved.

[0138] In some other embodiments, when there are two guide members, they may also be disposed on one side of the heating chamber 115. For example, they may both be located on the side where the aerosol-generating article 2 enters the heating chamber 115, or on the side where the aerosol-generating article 2 leaves the heating chamber 115, in order to improve the pressing effect on the disposed side.

[0139] In some other embodiments, when the medium traversal unit 40 includes only one guide, it may be disposed on only one side of the heating cavity 115 or located within the heating cavity 115. Alternatively, the guide may be irregularly shaped with a curved or bent shape, with its two ends pressing against the aerosol generating articles 2 on opposite sides of the heating cavity 115, while the middle part is separated from the aerosol generating articles 2.

[0140] In some other embodiments, at least one of the first guide member 43 and the second guide member 44 may be disposed outside the heating cavity 115, or disposed at positions adjacent to the heating cavity 115 and the first accommodating cavity 112 and the second accommodating cavity 113, respectively.

[0141] In some embodiments, the guide may have at least one guide wall for contacting the aerosol generating article 2. The guide wall is a curved wall that protrudes toward the aerosol generating article 2 to press against the aerosol generating article 2 and make it fit tightly against the separator 13.

[0142] Thus, when the surface of the aerosol generating article 2 has uneven protrusions, the guide wall can reduce the frictional resistance with the aerosol generating article 2 by utilizing its own curved protrusion features, which helps the part of the aerosol generating article 2 with uneven protrusions to pass smoothly, thereby improving the smoothness of the movement of the aerosol generating article 2 along the traversal path.

[0143] Specifically, the guide wall can be a developable surface or a non-developable surface.

[0144] When the guide wall is a developable surface wall, the generatrix of its developable surface extends approximately perpendicular to the direction of movement of the aerosol-generated product 2 within the heating chamber 115.

[0145] For example Figure 2 and Figure 3 In the embodiment shown, the first guide 43 and the second guide 44 can be smooth cylindrical rollers, which are rotatably disposed in the heating chamber 115 and located on opposite sides of the heating chamber 115 along the traversal path of the aerosol-generated article 2.

[0146] The cylindrical sidewalls of the two guide members can be considered as guide walls with curved protrusions. The axial direction of these guide walls is parallel to the generatrix and perpendicular to the direction of movement of the aerosol-generating product 2 within the heating chamber 115.

[0147] This application sets the first guide member 43 and the second guide member 44 in a cylindrical shape, with their generatrices extending perpendicular to the direction of movement of the aerosol generating product 2 within the heating chamber 115. This allows the guide walls to reduce friction with the aerosol generating product 2 by utilizing curved protrusions, while simultaneously separating the heating chamber 115 from the first accommodating chamber 112 and the second accommodating chamber 113, thereby preventing aerosol from diffusing into the two accommodating chambers.

[0148] This application further improves the smoothness of transporting the aerosol-generating product 2 by rotatably arranging the first guide member 43 and the second guide member 44 within the heating chamber 115. When there are protrusions on the surface of the aerosol-generating product 2, the first guide member 43 and the second guide member 44 can further reduce the friction with the aerosol-generating product 2 through their own rolling, facilitating the smooth transport of the aerosol-generating product 2 and avoiding problems such as tearing and breakage.

[0149] Specifically, the main body 11 and the cover 12 are recessed at the positions corresponding to the first guide member 43 and the second guide member 44 to form limiting grooves 16, so as to limit the two ends of the first guide member 43 and the second guide member 44 within the limiting grooves 16, thereby limiting the first guide member 43 and the second guide member 44 within the heating cavity 115.

[0150] It should be understood that the first guide member 43 and the second guide member 44 are rotatably disposed within the heating chamber 115, which can be specifically implemented by referring to the aforementioned method of rotating the drum, and will not be repeated here.

[0151] In some other embodiments, the first guide 43 and the second guide 44 may also be configured as roller structures with a drive unit 422. An external drive mechanism enables the first guide 43, the second guide 44, and the second roller 42 to rotate synchronously.

[0152] In other embodiments, the first guide 43 and / or the second guide 44 may also be configured as an elliptical column, a cone, a frustum, a semi-cylindrical shape, a sphere, an ellipsoid, a hemisphere, an irregular column, a polygonal column with rounded chamfers, or other shapes with curved walls.

[0153] In some other embodiments, the guide may also be configured with an irregular shape. For example, when there is only one guide, its two ends along the traversing path direction press the aerosol generating article 2 onto the separator 13. The remaining part is spaced apart from the aerosol generating article 2 and is located inside or outside the heating chamber 115.

[0154] In some other embodiments, the guide member can also be non-rotatably fixed within the heating chamber 115. As the aerosol-generating product 2 moves along the traversal path, the guide member and the aerosol-generating product 2 move against each other through friction. At this time, the first guide member 43 and the second guide member 44 can be configured in any shape, such as plate-shaped, column-shaped, or polygonal. By providing a guide wall with a curved protrusion structure, such as a hemispherical, semi-cylindrical, or semi-ellipsoidal shape, on the side of the guide member facing the aerosol-generating product 2, the aerosol-generating product 2 can be pressed tightly onto the separator 13 while reducing the frictional resistance with the aerosol-generating product 2.

[0155] In some other embodiments, the first guide 43 and / or the second guide 44 may also be configured as a flat rectangular plate, a polygonal column, a pyramidal shape, an irregular shape, or other shapes that do not have curved walls, and are only used to press the aerosol-generated product 2 onto the separator 13.

[0156] like Figures 5 to 8As shown, in some embodiments, the first guide member 43 and the second guide member 44 are spaced apart from the separator 13. The gap between the first guide member 43 and the second guide member 44 and the separator 13 is just enough for the aerosol-generating article 2 to pass through. At the same time, the first guide member 43 and the second guide member 44 are as close as possible to the side wall 1101 of the main body 11 to reduce the gap between them and the side wall 1101.

[0157] This arrangement allows the first guide member 43, the second guide member 44, the partition 13, the chamber wall of the heating chamber 115, and the airflow guiding unit 30 located within the heating chamber 115 to collectively define the airflow chamber 100. This airflow chamber 100 can communicate with the air guide hole 117 and the air outlet 121 respectively. That is, the first guide member 43 and the second guide member 44 also serve to partition the chamber, thereby reducing the communication area between the heating chamber 115 and the first accommodating chamber 112 and the second accommodating chamber 113 respectively.

[0158] This configuration reduces the spread of aerosols generated during heating into the first and second accommodating cavities 112 and 113, thereby reducing contamination of unheated areas of the aerosol-generating product 2, increasing the utilization rate of aerosols within the heating chamber 115, and further ensuring consistent heating effects across all areas of the aerosol-generating product 2 during the heating process. Simultaneously, it also reduces the spread of impurities and odors generated in the second accommodating cavity 113 after heating into the heating chamber 115, thus ensuring the purity of the aerosols within the heating chamber 115 and preventing any impact on the user's inhalation experience.

[0159] Further reading Figure 9 The housing unit 10 also includes at least two baffle structures 14. The baffle structure 14 is located inside the heating chamber 115 and is disposed on the side wall 1101 of the main body 11, and is respectively disposed with the first guide member 43 and the second guide member 44, so as to reduce the gap between the guide member and the chamber wall of the heating chamber 115, improve the relative independence of the heating chamber 115, and further reduce the outward diffusion of aerosol.

[0160] Specifically, the barrier structure 14 corresponding to the second guide member 44 will be described in detail below. The barrier structure 14 may include a first barrier member 141 and a second barrier member 142. The first barrier member 141 and the second barrier member 142 may be longitudinally elongated ribs or protruding ribs, and are arranged parallel to the axial direction of the second guide member 44.

[0161] The plane defined by the axes of the first barrier 141 and the second guide 44 is perpendicular to the side wall 1101 where the first barrier 141 is located. That is, the first barrier 141 is located at the position where the distance between the second guide 44 and the side wall 1101 is minimal. The cross-section of the first barrier 141 perpendicular to the axis is approximately triangular, with its apex pointing towards the second guide 44. The second barrier 142 is located on one side of the first barrier 141, and its cross-section perpendicular to the axis is also approximately triangular, with one side approximately tangent to the outer peripheral surface of the second guide 44.

[0162] By setting the first baffle 141 and the second baffle 142, two barriers can be formed, which improves the separation effect between the heating chamber 115 and the first accommodating chamber 112 and the second accommodating chamber 113, and further avoids the diffusion of aerosols.

[0163] In some other embodiments, the barrier structure 14 may include only one barrier member or multiple barrier members. Of course, the cross-sectional shape of the barrier member perpendicular to the axis may also be set as a polygon, irregular shape, circle, ellipse, semicircle, irregular shape, or other shapes.

[0164] In other embodiments, the diameter of the first guide member 43 and the second guide member 44 may be reduced, or the first guide member 43 and / or the second guide member 44 may be configured as other non-columnar shapes, solely for pressing the aerosol-generating article 2 onto the separator 13. In this case, separator plates may also be spaced apart on both sides of the airflow guiding unit 30 within the housing unit 10, thereby separating the airflow chamber 100 from the first accommodating cavity 112 and the second accommodating cavity 113. In such embodiments, the first guide member 43 and the second guide member 44 may be located inside or outside the airflow chamber 100.

[0165] In some other embodiments, the medium traversal unit 40 may include only one guide member, and one or at least two guide walls are provided on the guide member at intervals along the moving direction of the aerosol generating article 2 in the heating chamber 115 to achieve the pressing of the aerosol generating article 2 and the separator 13.

[0166] like Figure 4 and Figure 11 As shown, in some embodiments, the airflow guiding unit 30 is disposed on the side wall 1101 of the main body 11 and located between the first guide member 43 and the second guide member 44. It is used to guide the airflow in conjunction with the guide members, providing an air path structure for the output of aerosols, improving the aerosol extraction rate, and preventing aerosols from diffusing into other chambers. The airflow guiding unit 30 includes an airflow guiding structure 31 and at least two protruding structures 32.

[0167] The airflow guiding structure 31 defines a guide groove 311 for mixing and rectifying the airflow, balancing the generation and transport efficiency of the aerosol-generated product 2 at various locations along the airflow direction within the heating chamber 115, thereby further reducing the diffusion of aerosols to other chambers and achieving a uniform aerosol extraction effect. The protruding structure 32 is disposed on the airflow guiding structure 31 and located on both sides of the guide groove 311, for filtering and purifying the airflow, thus achieving a directional rectification effect.

[0168] Specifically, the guide channel 311 is formed on the side of the airflow guiding structure 31 facing the separator 13, such that the opening of the guide channel 311 faces the separator 13, the receiving cavity 111, and the aerosol generating article 2. The guide channel 311 is located inside the airflow chamber 100, and the channel wall of the guide channel 311 is also a component of the chamber wall of the airflow chamber 100.

[0169] like Figures 5 to 7 As shown, in some embodiments, along the direction of the airflow within the airflow chamber 100, the flow area of ​​at least a partially truncated section of the airflow chamber 100 gradually decreases.

[0170] Specifically, the flow area can be understood as the cross-sectional area of ​​a pipe or channel perpendicular to the velocity vector direction along the flow direction of the fluid flow area. That is, along the flow direction of the airflow within the airflow chamber 100, the cross-sectional area of ​​the airflow chamber 100 perpendicular to the airflow velocity vector direction.

[0171] Specifically, the side of the airflow guiding structure 31 facing the separator 13 is inclined. Along the direction of the airflow within the airflow chamber 100, the thickness of the airflow guiding structure 31 gradually increases, and the distance between its side facing the separator 13 and the separator 13 gradually decreases.

[0172] Therefore, along the direction of the airflow within the airflow chamber 100, the flow area of ​​the airflow chamber 100 decreases, meaning that the cross-sectional dimension of the airflow chamber 100 perpendicular to the axial direction of the shell gradually decreases. The distance between the wall of at least a partially truncated section of the guide channel 311 and the aerosol-generating product 2 within the heating chamber 115 also gradually decreases. In other words, along the direction of the airflow within the airflow chamber 100, the flow area of ​​at least a partially truncated section of the guide channel 311 also gradually decreases.

[0173] It should be understood that the cross-sectional shape of the guide channel 311 perpendicular to the extension direction can be set to various shapes such as semi-circle, U-shape, various arc shapes, irregular shapes, polygons, etc., and no specific limitation is made here.

[0174] It should be noted that the flow area of ​​at least part of the airflow chamber 100 and the guide channel 311 gradually decreases, as can be seen from the following: Figure 4As shown, the flow area of ​​the airflow chamber 100 and the guide channel 311 gradually decreases along the airflow direction. Alternatively, one section of the airflow chamber 100 and guide channel 311 may have a gradually decreasing flow area along the airflow direction, while the flow area of ​​the remaining sections of the airflow chamber 100 and guide channel 311 may remain unchanged, change irregularly, or gradually increase. Furthermore, two sections of the airflow chamber 100 and guide channel 311, at least two intervals apart, may have a gradually decreasing flow area along the airflow direction, while the flow area of ​​the remaining sections of the airflow chamber 100 and guide channel 311 may remain unchanged, change irregularly, or gradually increase.

[0175] like Figure 11 As shown, in some embodiments, the protrusion structure 32 may include a plurality of protrusions arranged in a uniform array. Specifically, the plurality of protrusions may be arranged in an array and have a significant protrusion relative to other planes.

[0176] The protrusion can be spherical, hemispherical, cuboid, polygonal, or various prism shapes, and has a significant protrusion shape relative to the surface on which it is set; no specific limitation is made here. The array arrangement of multiple protrusions can adopt various regular array arrangements such as linear row matrices or rectangular square matrices; no specific limitation is made here either.

[0177] exist Figure 11 In the illustrated embodiment, there are two protrusion structures 32, and the multiple protrusions of each protrusion structure 32 are arranged in a regular linear array, extending along the airflow direction within the airflow chamber 100. Both protrusion structures 32 are disposed on the airflow guide structure 31 and are symmetrically located on opposite sides of the guide groove 311.

[0178] In some other embodiments, the protrusions in each protrusion structure 32 may also be arranged in a matrix or other array. Of course, the protrusions in the protrusion structure 32 may also be arranged in other regular arrangements such as radial, annular, or gradient arrangements, or in irregular arrangements such as directional or random arrangements.

[0179] In some other embodiments, the number of protrusions 32 may be set to one, located only on one side of the guide channel 311. Alternatively, the number of protrusions 32 may be set to three or more, with at least two protrusions 32 provided on at least one side of the guide channel 311.

[0180] This application, by setting at least a partially truncated guide channel 311 with a flow area that gradually decreases with the direction of airflow, can, based on the principles of variable cross-section mixing and turbulent section rectification, ensure that the airflow entering the airflow chamber 100 is fully mixed with aerosol in the upstream region of the airflow chamber 100 to form a secondary reflux, and undergoes secondary mixing in the downstream region. This balances the extraction of aerosol generated from the sheet-like aerosol product 2 and the aerosol generated at corresponding upstream and downstream positions within the airflow chamber 100, thereby reducing the amount of aerosol condensation and retention in the downstream region of the airflow chamber 100, improving the aerosol extraction efficiency, and achieving a uniform extraction effect for the sheet-like aerosol product 2.

[0181] This application, by setting a protruding structure 32, can perform wave-damping and flow filtering in a direction perpendicular to the airflow direction, and rectify the diffused incoming gas under the absorption and reflection of the protruding surface. When the airflow direction is not the extension direction of the guide groove 311, it can quickly interact with the protruding surface of the protruding structure 32 to form a reflected wave. After the reflected wave accumulates, it rapidly impacts and further forms a rectified return flow of the guide airflow, thereby achieving a static directional rectification effect.

[0182] That is, the protruding structure 32 can integrate the airflow path in the airflow chamber 100 through the anti-wave beam effect and guide the airflow to the air outlet 121, further reducing the phenomenon of anisotropic diffusion and the formation of branch flow during the aerosol production process, further reducing the contamination of the first accommodating cavity 112 and the second accommodating cavity 113 by aerosols, and improving the aerosol extraction rate.

[0183] Table 1 shows a comparison of airflow parameters in the aerosol extraction process between the microwave heating module 1 equipped with the airflow guiding unit 30 and the microwave heating module 1 without the airflow guiding unit 30.

[0184] (Table 1 Comparison of airflow characteristic parameters during aerosol extraction) based on Figure 21 , Figure 22 As shown in Table 1, without the airflow guiding unit 30, the airflow velocity within the airflow chamber 100 is relatively low during aerosol extraction, and the flow rates of the main flow, tributaries, and return flow are all relatively low. Combined with... Figure 31 , Figure 32 and Figure 33 As shown, the aerosol extraction process involves numerous countercurrents, leading to reduced extraction efficiency and significant aerosol contamination of both the first and second accommodating chambers 112 and 113. Further analysis... Figure 25 , Figure 26 and Figure 27It is known that due to the presence of reflux and a large number of opposite branches, the pressure loss of the microwave heating module is large during the aerosol extraction process, and the stress distribution in the non-airflow chamber area of ​​the shell is large, which is not conducive to the structural strength and service life of the shell unit 10.

[0185] based on Figure 23 , Figure 24 As shown in Table 1, with the airflow guiding unit 30 installed, the velocity of the core airflow during aerosol extraction is significantly increased, by more than 54%, and the proportion of the core airflow increases to 92.39%, essentially eliminating tributaries and backflow phenomena. Comparing the backflow proportion in the downstream section of the airflow chamber 100, it can be seen that under the action of the guide channel 311, the aerosol extraction rate in the downstream section of the airflow chamber 100 increases significantly, effectively preventing aerosol condensation and backflow losses within the shell. Combined with... Figure 34 , Figure 35 and Figure 36 As shown, the anomaly stream during aerosol extraction is significantly reduced, and the problem of aerosol contamination of the first chamber 112 and the second chamber 113 is significantly alleviated, further improving the aerosol extraction efficiency. Further combined with... Figure 28 , Figure 29 and Figure 30 It can be seen that, due to the significant reduction in tributaries and backflow phenomena, the pressure loss of the microwave heating module is significantly reduced during aerosol extraction, and the stress on the non-airflow chamber area of ​​the shell is significantly reduced.

[0186] It is important to understand that the upstream and downstream regions of the airflow within the airflow chamber 100 are defined based on the direction of the airflow during the aerosol extraction process. Specifically, the upstream region can be understood as the area the airflow first passes through within the airflow chamber 100, and the downstream region as the area it passes through subsequently.

[0187] Furthermore, based on the flow path of the airflow within the airflow chamber 100, the upstream section of the airflow chamber 100 can be understood as the area segment involved in the first 50% of the flow path of the airflow within the airflow chamber 100. The downstream region within the airflow chamber 100 can be understood as the area segment involved in the last 50% of the flow path of the airflow within the airflow chamber 100.

[0188] It is important to understand that the area through which the airflow passes from the guide hole 117 to the outlet 121 can be divided into core airflow and non-core airflow. Specifically, if the airflow flows from the guide hole 117 through the airflow chamber 100 to the outlet 121, it can be considered core airflow. If the airflow enters the space outside the airflow chamber 100, such as the first receiving cavity 112 or the second receiving cavity 113, it can be considered non-core airflow. Therefore, the flow rate proportion within the airflow chamber 100 can be understood as the core airflow proportion. Figures 31 to 36As shown in the diagram, by setting up the airflow guiding unit 30, the proportion of core airflow can be significantly increased and the proportion of non-core airflow can be reduced.

[0189] It should be understood that the airflow guiding structure 31 can be detachably or non-detachably installed within the housing through various methods such as integral molding, welding, adhesive connection, bolt connection, snap-fit ​​connection, and sliding groove connection. Similarly, the protruding structure 32 can also be detachably or non-detachably installed on the airflow guiding structure 31 or the housing through various methods such as integral molding, welding, adhesive connection, bolt connection, snap-fit ​​connection, and sliding groove connection. No specific limitations are made here.

[0190] like Figures 5 to 9 As shown, in some embodiments, along the traversal path of the aerosol-generating article 2 within the heating chamber 115, the airflow guiding structure 31 is approximately located at the center of the heating chamber 115, and the first guide member 43 and the second guide member 44 are symmetrically arranged on opposite sides of the airflow guiding structure 31. Along the traversal path of the aerosol-generating article 2 within the heating chamber 115, the flow channel 311 is approximately located at the center of the airflow guiding structure 31, and at least two protruding structures 32 are symmetrically arranged on opposite sides of the flow channel 311.

[0191] This configuration can improve the uniformity of airflow distribution within the heating chamber 115, further enhancing the guiding effect of the airflow guiding unit 30.

[0192] like Figure 4 As shown, in some embodiments, the air guide hole 117 on the main body 11 and the air outlet hole 121 on the cover 12 are located at both ends of the guide groove 311 and are correspondingly arranged with the guide groove 311. This arrangement can further improve the aerosol extraction rate and reduce the diffusion of aerosols into the first accommodating cavity 112 and the second accommodating cavity 113.

[0193] See also Figure 11 In some embodiments, the protrusion 32 is disposed at one end of the airflow guiding structure 31 near the air guide hole 117, and is located approximately in the upstream region of the airflow chamber 100 along the direction of the airflow.

[0194] In some other embodiments, the number of the protrusion structure 32 may be set to at least three, and at least two protrusion structures 32 may be provided on at least one side of the guide groove 311.

[0195] In some other embodiments, the protrusion structure 32 may also be directly disposed on the side wall of the main body 11, located on the side of the airflow guiding structure 31.

[0196] In some other embodiments, the airflow guiding unit 30 may only include the airflow guiding structure 31, or only the protruding structure 32. Of course, the microwave heating module 1 may also omit the airflow guiding unit 30, by adjusting the size of the heating cavity 115, the air guide hole 117, and the relative position of the air outlet 121 with the heating cavity 115.

[0197] Figures 38 to 40 The microwave heating module 1A in the second embodiment of the application is shown. The main difference between it and the microwave heating module 1 in the first embodiment is that the inner conductor structure 22A is different.

[0198] Specifically, the second part 2212A of the connecting part 221A is far from the end of the first part 2211A and is connected to the middle part of the microwave radiating part 222A, so that the structure after the second part 2212A is connected to the microwave radiating part 222A is roughly T-shaped.

[0199] It should be noted that the specific connection point between the microwave radiating section 222A and the second part 2212A can be any location other than the end, and is not specifically limited here. For example, in Figure 39 In the embodiment shown, the midpoint of the extending direction of the microwave radiating part 222A is connected to the second part 2212A.

[0200] like Figure 37 and Figure 40 As shown in the diagram, the electric field intensity distribution during the operation of inner conductor structures with different shapes shows that inner conductor structure 22 and inner conductor structure 22A can generate similar electric field distributions during the operation, that is, the two can achieve similar heating effects on aerosol-generated products 2.

[0201] Meanwhile, by connecting the second part 2212A to the middle position of the microwave radiating part 222A, the structure after the connection is roughly T-shaped, which makes the electric field constructed during operation more uniform, and the hot spots are roughly symmetrically distributed vertically, thereby heating the aerosol to generate product 2A more uniformly.

[0202] Figure 41 and Figure 42 The microwave heating module 1B in the third embodiment of this application is shown. The main difference between it and the microwave heating module 1 in the first embodiment is that in this embodiment, the guide member and the airflow guiding unit 30B are integrally arranged.

[0203] Specifically, such as Figure 42 As shown, the first guide member 43B and the second guide member 44B are both non-rotatable cylindrical and are integrally disposed on opposite sides of the airflow guiding structure 31B along the moving direction of the aerosol generating product 2B, so as to simplify the structural features of the microwave heating module 1B.

[0204] It should be noted that the integration of the first guide member 43B and the second guide member 44B can be achieved through methods such as integral molding, welding, or glue connection, and no specific limitation is made here.

[0205] In some other embodiments, the first guide 43B and / or the second guide 44B may also be connected to the heating chamber ( Figure 41 and Figure 42 The chamber walls (not shown in the image) are integrally formed.

[0206] Furthermore, in this embodiment, the protrusion structure 32B is arranged along the extension direction of the guide groove 311B, and extends approximately from one end of the airflow chamber 100B to the other end along the direction of the airflow.

[0207] This application also provides an aerosol generating device, which may include the microwave heating module in any of the foregoing embodiments.

[0208] In some embodiments, the aerosol generating apparatus may further include a microwave feed module (not shown in the figure), which can make ohmic contact with the inner conductor structure of the microwave heating unit and be externally connected to a microwave generating unit to feed microwaves into the microwave heating unit.

[0209] This application also constructs an aerosol generation system, which may include sheet-like or strip-like aerosol generation articles and the microwave heating module in any of the foregoing embodiments.

[0210] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0211] 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.
