Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0042] The aerosol generating device provided in the embodiments of the present application is now described.

[0043] See also Figures 1 to 4 As shown, the aerosol generating device provided in the embodiment of the present application includes a main body shell 100, and a magnetic induction heating component 200 and a detachably connected matrix box 300 are provided in the main body shell 100.

[0044] Wherein, the matrix box 300 includes a shell 301 and a matrix band 302, a first reel 303 and a second reel 304 arranged in the shell 301, the matrix band 302 is at least partially wound around the first reel 303 and the second reel 304, and the first reel 303 or the second reel 304 rotates to drive the matrix band 302 to move between the first reel 303 and the second reel 304, and the matrix band 302 is provided with a magnetic induction heating material, for example, the magnetic induction heating material can be a magnetic induction heating layer 3021. The magnetic induction heating material can also be discrete particles, spaced layers, etc.

[0045] The magnetic induction heating assembly 200 includes at least two magnetic induction coils 201 , which are respectively arranged on both sides of the substrate tape 302 between the first reel 303 and the second reel 304 along the thickness direction of the substrate tape 302 .

[0046] The aerosol generating device provided in this embodiment is provided with at least two magnetic induction coils 201, and the at least two magnetic induction coils 201 are respectively arranged on both sides of the substrate strip 302 along the thickness direction of the substrate strip 302. The at least two magnetic induction coils 201 can work simultaneously and form a superimposed magnetic field, which is conducive to rapid heating of the substrate strip 302, reducing the preheating time and increasing the amount of smoke, thereby improving the user experience.

[0047] Generally, the host housing 100 may be a rectangular structure having a volume, for example, a cuboid structure with a height greater than a width.

[0048] In some embodiments, the generating device further includes a power supply and control assembly 500. The aforementioned matrix box 300 is disposed in the upper space of the main housing 100. The top of the outer shell 301 of the matrix box 300 is provided with an air outlet 101. The power supply and control assembly 500 is disposed in the lower space of the main housing 100. The height direction and the layer thickness direction are perpendicular to each other, and the thickness direction can be understood as the width direction of the main housing 100.

[0049] The matrix box 300 is arranged in the upper part of the space, which allows the magnetic induction heating component 200 and part of the matrix belt 302 to be arranged between the air outlet 101 and the power supply and control component 500. The aerosol generated by the heating and atomization of the matrix belt 302 can flow in the direction of the power supply and control component 500 pointing to the air outlet 101. By designing the spatial position of the power supply and control component 500, the air outlet 101, the magnetic induction heating component 200 and the matrix belt 302, it is convenient to arrange at least two magnetic induction coils 201 and the matrix belt 302, and the flow path of the aerosol is smoother and conforms to the assembly layout of the generating device.

[0050] For example, the power supply and control component 500 avoids the upper part of the space of the main body shell 100, so that the internal space of the shell 301 of the matrix box 300 is sufficient for use, allowing the two magnetic induction coils 201 on both sides of the matrix belt 302 to be arranged in the width direction, allowing at least two magnetic induction coils 201 on the same side of the matrix belt 302 to be arranged in the height direction, allowing the matrix belt 302 to have a certain extension length in the height direction, and allowing the generated aerosol to flow toward the air outlet 101 along the extension direction of the matrix belt 302.

[0051] The interior of the shell 301 of the matrix box 300 can be divided into an atomization chamber and a receiving chamber. The atomization chamber and the receiving chamber are arranged along the width direction. The atomization chamber is connected to the outside through the air outlet 101. The matrix strip 302 can be atomized in the atomization chamber and generate an aerosol. The aerosol is discharged through the air outlet 101 for the user to inhale.

[0052] The circumferential outer side of the first reel 303 is used to wind the substrate tape 302. The substrate tape 302 can be unwound from the first reel 303 and wound around the circumferential outer side of the second reel 304 after passing through the atomization chamber. That is, the substrate tape 302 before atomization is unwound from the first reel 303 and wound around the second reel 304 after atomization.

[0053] For example, the two ends of the substrate tape 302 are respectively wound around the outer periphery of the first reel 303 and the outer periphery of the second reel 304. By controlling the rotation of the second reel 304, the substrate tape 302 wound on the first reel 303 is driven to pass through the atomization chamber and be wound onto the second reel 304. The rotation direction of the second reel 304 can be clockwise or counterclockwise.

[0054] Here, unwinding refers to the process of peeling the rolled substrate radially, separating the outer layer from the inner layer of the substrate. The substrate tape 302 is wound around the circumferential outer side of the first reel 303. The substrate tape 302 can be unwound from the first reel 303, which refers to the process of separating the outer layer from the inner layer of the substrate tape 302.

[0055] Here, winding refers to a method of taking up a continuous product using a reel, a drum, or the like. The substrate strip 302, after passing through the atomization chamber, is wound around the circumferential outer side of the second reel 304 and is wound up by the second reel 304. This refers to the process of taking up the atomized substrate strip 302 using the second reel 304, i.e., rolling it into a roll.

[0056] The matrix box is detachably disposed in the upper space of the main body housing 100, and a replacement port can be provided on the side of the accommodating chamber away from the atomizing chamber. When the replacement port is in a closed state, the matrix box can be activated to heat the matrix belt 302. When the replacement port is in an open state, the matrix box can be replaced, which may include but is not limited to replacing the matrix belt 302.

[0057] In some embodiments, the matrix tape 302 includes a first matrix tape 302a and a second matrix tape 302b arranged in parallel and stacked. The first matrix tape 302a and the second matrix tape 302b both include a magnetic induction heating layer 3021 and a matrix layer 3022 arranged on the magnetic induction heating layer 3021. The matrix layer 3022 can be heated by the magnetic induction heating layer 3021 and generate an aerosol. The matrix layer 3022 of the first matrix tape 302a and the matrix layer 3022 of the second matrix tape 302b are arranged to face away from each other.

[0058] Each magnetic induction heating layer 3021 acts on the matrix layer 3022 stacked therewith, so that each matrix layer 3022 is independently heated and atomized, further improving the smoke output speed and smoke output, thereby further improving the user experience.

[0059] In some embodiments, an insulating layer 3023 is further provided between the first substrate strip 302a and the second substrate strip 302b.

[0060] The insulating layer 3023 is used to isolate the magnetic induction heating layers 3021 on both sides thereof, thereby further ensuring that each magnetic induction heating layer 3021 can act on the matrix layer 3022 stacked therewith respectively, preventing the heating heat from flowing between the two magnetic induction heating layers 3021, thereby preventing the independent heating atomization effect of each matrix layer 3022 from being affected.

[0061] In some embodiments, the matrix layer 3022 of the first matrix strip 302a and the matrix layer 3022 of the second matrix strip 302b are made of different materials or have different densities.

[0062] The materials of the two matrix layers 3022 are the same or different, and the densities of the two matrix layers 3022 are the same or different.

[0063] On the one hand, the two substrate layers 3022 are made of the same material and density, allowing the magnetic induction coils 201 on either side to heat both substrate layers 3022 simultaneously, thereby increasing vapor production. On the other hand, if the two substrate layers 3022 are made of different materials, they will have different characteristic aromas, producing different mouthfeels when heated, thereby enhancing the richness of the tobacco aroma. Alternatively, if the two substrate layers 3022 are made of different materials, the magnetic induction coils 201 on either side can simultaneously heat both substrate layers 3022, also increasing vapor production.

[0064] In some embodiments, the substrate tape 302 includes a magnetic induction heating layer 3021 , a first substrate layer 3022 , and a second substrate layer 3022 , wherein the magnetic induction heating layer 3021 is sandwiched between the first substrate layer 3022 and the second substrate layer 3022 .

[0065] By acting on different sides of the same magnetic induction heating layer 3021 on the matrix layer 3022 stacked therewith, each matrix layer 3022 is independently heated and atomized, further improving the smoke output speed and smoke output, thereby further improving the user experience.

[0066] Specifically, the substrate strip 302 is a flexible, long strip structure with a certain width and thickness, but the length can be extended and bent according to actual conditions. The magnetic induction heating layer 3021 can be any strip layer that can withstand the atomization temperature, has a certain degree of flexibility, and can be unwound and rewound, such as a metal strip layer, a graphite strip layer, or a strip layer formed by braiding metal wires. The thickness of the magnetic induction heating layer 3021 can be between 0.005 and 0.2 mm, and two substrate strips 302 can be adhered to the two surfaces of the magnetic induction heating layer 3021.

[0067] In some embodiments, at least two magnetic induction coils 201 are symmetrically arranged on both sides of the substrate tape 302 in the layer thickness direction.

[0068] At least two magnetic induction coils 201 are symmetrically arranged on both sides of the matrix strip 302 in the layer thickness direction, so that the heating and atomization speed of the two matrix layers 3022 at the same position is more consistent and faster, which is more conducive to rapid smoke output and easier to achieve the purpose of instant smoking and stopping.

[0069] In some embodiments, at least two magnetic induction coils 201 are arranged on both sides of the matrix tape 302 in the layer thickness direction, and at least one magnetic induction coil 201 located on one side in the layer thickness direction and at least one magnetic induction coil 201 located on the other side in the layer thickness direction are staggered along the extension direction of the matrix tape 302.

[0070] On both sides of the matrix strip 302 in the layer thickness direction, the magnetic induction coils 201 are staggered in equal or unequal numbers, and each magnetic induction coil 201 corresponds to a high-temperature zone. The resulting high-temperature zone ranges are also staggered, which is beneficial to increase the total area of ​​the high-temperature zone required for heating and atomization, thereby increasing the amount of smoke in the matrix layer 3022 per unit time, thereby further improving the user experience.

[0071] The structures of at least two magnetic induction coils 201 can be the same or different. For example, the magnetic induction coils 201 can be Figures 5 to 7 Any one of the magnetic induction coils 201.

[0072] Among them, the structures of the magnetic induction coils 201 are the same. For example, the magnetic core and the coil are set in the same manner, so the magnetic field and temperature field generated by each magnetic induction coil 201 are consistent. In this way, the magnetic field strength and heating capacity used for heating and atomization can be further enhanced and consistent, and the heating and atomization speeds of the two matrix layers 3022 can be more consistent and faster, which is more conducive to rapid smoke output.

[0073] Among them, the structures of the magnetic induction coils 201 are different. For example, at least one of the magnetic core and the coil is configured differently. Then, the magnetic fields and temperature fields generated by the different magnetic induction coils 201 are differentiated. The matrix layer 3022 is heated by the differentiated temperature fields, so that the aerosol obtained by atomization has a richer taste layer, which is conducive to stimulating a variety of tobacco flavors, thereby further improving the user experience.

[0074] In some embodiments, the space between the magnetic induction coils 201 disposed on both sides of the substrate belt 302 is a heating area, and the heating area is part of the internal space of the atomization chamber.

[0075] An air inlet 103 and an air outlet 101 are provided on the outer shell 301. The matrix box 300 also includes a first air duct 102 arranged between the air inlet 103 and the air outlet 101. The first air duct 102 passes through the heating area, and the extension direction of the first air duct 102 is parallel to the moving direction of the matrix belt 302 between the first reel 303 and the second reel 304. The air inlet 103 and the air outlet 101 are respectively located on both sides of the heating area.

[0076] The air inlet 103 is provided for the entry of external airflow, and during inhalation, the airflow directly passes through the heating area, and can drive the aerosol to reach the air outlet 101 smoothly.

[0077] In some embodiments, the space between the magnetic induction coils 201 arranged on both sides of the matrix belt 302 is a heating area, and an air inlet 103 and an air outlet 101 are provided on the outer shell 301. The matrix box 300 also includes a first air duct 102, which passes through the heating area. The air inlet 103 and the air outlet 101 are located on the same side of the heating area.

[0078] The air inlet 103 is provided for the entry of external airflow. When inhaling, the airflow does not directly pass through the heating zone, but uses negative pressure to draw away the aerosol. This method avoids the cold air from the air inlet passing through the heating zone and taking away the heat of the magnetic induction coil 201 and the matrix layer 3022, which is beneficial to maintaining the temperature of the atomization zone and improving energy utilization.

[0079] The first air channel 102 is provided with a through hole 104, which includes a first through hole 1041 and a second through hole 1042. The first through hole 1041 and the second through hole 1042 are both connected to the air outlet 101 through an air outlet channel. The first through hole 1041 is adjacent to the magnetic induction heating component 200, and the second through hole 1042 is farther away from the magnetic induction heating component 200. The diameter of the first through hole 1041 is larger than the diameter of the second through hole 1042.

[0080] There may be one or more second via holes 1042 . When there are multiple second via holes 1042 , the diameter of the first via hole 1041 is larger than the total diameter of the multiple second via holes 1042 .

[0081] Thus, the first through-hole 1041, which is closer to the magnetic induction heating assembly 200, is designed with a large diameter. As the primary passage for aerosol, the large diameter ensures the passage of a large amount of smoke. The second through-hole 1042, with a smaller diameter, has a higher airflow velocity, which can more effectively remove the remaining small amount of aerosol, thereby improving aerosol utilization.

[0082] In some embodiments, the main body housing 100 is further provided with a suction nozzle 400 connected to the first air channel 102 , and the air inlet 103 and the air outlet 101 are located on a side close to the suction nozzle 400 .

[0083] The nozzle 400 contains a filter device, which may include filter cotton 401 and a filter element 402, which can filter impurities in the aerosol and reduce the temperature of the aerosol, thereby ensuring the user's smoking taste.

[0084] The filter cotton 401 can be arranged in a circular pattern in the upper portion of the outlet channel, adjacent to the outlet 101, and has a central channel. The filter element 402 is located in the middle portion. The cross-section of the filter element 402 is consistent with the cross-section of the outlet channel, and the bottom end of the filter element 402 is aligned with or higher than the top line of the second through hole 1042 to ensure the normal passage of aerosols.

[0085] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
