Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to an aerosol generation product and an aerosol generation system. Background Technology

[0002] The working process of the aerosol generation system is that the aerosol generation component in the aerosol generation product generates aerosols by heating without combustion, and then the aerosols are discharged outside the aerosol generation product for users to use or inhale.

[0003] Current aerosol generation products generally draw outside air into the aerosol generation component, and then the airflow formed by the outside air entering the aerosol generation component carries away the aerosol in the aerosol generation component. However, during the user's aerosol extraction process, new outside air continuously enters the aerosol generation component, resulting in a high oxygen content inside the aerosol generation component. In an environment with a high oxygen content, the aerosol generation component must maintain a non-combustible heating temperature below the temperature that would cause combustion (such as 350°C), which limits the heating temperature of the aerosol generation component and leads to unsatisfactory atomization effect of the aerosol generation product. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of this application is that the atomization effect of existing aerosol-generated products is not ideal.

[0005] To address the aforementioned technical problems, this application provides an aerosol-generating product, employing the following technical solution:

[0006] The aerosol-generating article includes: a shell and an aerosol-generating component;

[0007] The interior of the housing is provided with an airflow channel, and the side wall of the housing is provided with an air inlet. The airflow channel is connected to the outside atmosphere through the air inlet.

[0008] The aerosol generating component is disposed inside the housing, and the airflow channel is located downstream of the aerosol generating component. The airflow channel is used to form a vortex airflow under suction to carry out the aerosol in the aerosol generating component. The end of the aerosol generating component away from the aerosol channel is sealed.

[0009] Furthermore, the airflow channel is vortex-shaped, and the central region of the vortex axis of the airflow channel is an aerosol channel, which is connected to the air outlet of the aerosol generation component.

[0010] Furthermore, the aerosol generating component includes a heating element and an aerosol generating substrate, wherein the aerosol generating substrate is in contact with the heating element, and the heating element is used to heat the aerosol generating substrate to form an aerosol.

[0011] Furthermore, the heating element is a tubular structure with an open top, the aerosol generating substrate is in contact with the outer wall of the heating element, and the inner cavity of the heating element is connected to the airflow channel through the top opening of the heating element.

[0012] Furthermore, the side wall of the heating element is provided with a vent hole, which is connected to the inner cavity of the heating element and is used to allow aerosols in the aerosol generating substrate to pass through.

[0013] Furthermore, the aerosol generating substrate and the airflow channel are sealed together.

[0014] Furthermore, it includes a first air-blocking component, which is disposed at the end of the aerosol generating component away from the airflow channel, and is used to isolate the aerosol generating component from the outside world.

[0015] Furthermore, it also includes a filter tip located downstream of the airflow channel.

[0016] Furthermore, it also includes a second air-blocking component, which is disposed between the airflow channel and the filter nozzle. The second air-blocking component has a connecting channel that communicates with the airflow channel, and the filter nozzle is connected to the end of the connecting channel away from the airflow channel.

[0017] To address the aforementioned technical problems, this application also provides an aerosol generation system, which employs the following technical solution:

[0018] The aerosol generation system includes a housing, a power supply component, an induction coil, and an aerosol generation product as described in any of the above embodiments. The power supply component and the induction coil are both disposed inside the housing. The power supply component is electrically connected to the induction coil. The aerosol generation product can be inserted into the interior of the housing.

[0019] When the aerosol generating article is inserted into the interior of the housing, the induction coil surrounds the outside of the aerosol generating component of the aerosol generating article.

[0020] Compared with the prior art, the embodiments of this application have the following main advantages:

[0021] The aerosol generating product provided in this application features an airflow channel downstream of the aerosol generating component. This allows outside air to bypass the aerosol generating component and directly enter the airflow channel, forming a vortex airflow that draws out the aerosol generated within the component. This achieves the goal of carrying the aerosol out without the outside air passing through the component, avoiding the impact of outside air on the heating temperature of the aerosol generating component. Without outside air flowing through the component, a higher heating temperature (up to 350°C) can be set, resulting in better atomization and improved heat retention. Furthermore, the aerosol generating component can enhance the flavor of the aerosol. After being drawn into the airflow channel, the aerosol flows along the channel with the vortex airflow, achieving efficient heat dissipation and allowing the aerosol to cool down and be discharged, thus improving the user experience.

[0034] Example 1 of the aerosol-generated article of this application

[0035] Embodiment 1 of this application provides an aerosol-generating product, see reference. Figures 1 to 5 The aerosol generating product includes a housing 110 and an aerosol generating assembly 120. An airflow channel 131 is provided inside the housing 110, and an air inlet 111 is provided on the side wall of the housing 110. The airflow channel 131 communicates with the outside atmosphere through the air inlet 111. The aerosol generating assembly 120 is disposed inside the housing 110, and the airflow channel 131 is located downstream of the aerosol generating assembly 120. The airflow channel 131 is used to form a vortex airflow under suction to carry out the aerosol in the aerosol generating assembly 120. The end of the aerosol generating assembly 120 away from the aerosol channel 131 is sealed.

[0036] Understandably, the working principle of this aerosol-generated product is as follows:

[0037] After the aerosol generating component 120 is heated and generates aerosol within the housing 110, the aerosol accumulates within the aerosol generating component 120. The end of the aerosol generating component 120 away from the aerosol channel 1311 is sealed, isolating the aerosol generating component 120 from the outside environment, preventing outside air from passing through it. When a user inhales the aerosol, the user applies suction to the airflow channel 131 at the end away from the aerosol generating component 120. At this time, outside air does not pass through the aerosol generating component 120 but directly enters the airflow channel 131 through the air inlet 111 on the side wall of the housing 110. The airflow channel 131 is located downstream of the aerosol generating component 120. After the outside air enters the airflow channel 131, a vortex airflow is formed downstream of the aerosol generating component 120. The vortex airflow makes the air pressure in the airflow channel 131 lower than the air pressure in the aerosol generating component 120, and a pressure difference is formed between the airflow channel 131 and the aerosol generating component 120. The vortex airflow draws out the aerosol in the aerosol generating component 120 and carries the aerosol out of the aerosol generating product.

[0038] It should be noted that the airflow channel 131 is located downstream of the aerosol generating component 120, meaning that aerosols flow from the aerosol generating component 120 to the airflow channel 131.

[0039] Compared with existing technologies, this aerosol-generated product has at least the following technical advantages:

[0040] This embodiment of the application provides an airflow channel 131 downstream of the aerosol generating component 120. The airflow channel 131 is connected to the outside through an air inlet 111 on the side wall of the housing 110. The end of the aerosol generating component 120 away from the airflow channel 131 is sealed, so that outside air does not pass through the aerosol generating component 120, but directly enters the airflow channel 131 from the air inlet 111 to form a vortex airflow, thereby drawing out the aerosol generated in the aerosol generating component 120. This achieves the goal of carrying out the aerosol without outside air passing through the aerosol generating component 120, avoiding the influence of outside air on the heating temperature of the aerosol generating component 120. This allows the heating temperature of the aerosol generating component 120 to be higher (up to 350°C), resulting in better atomization effect. The aerosol generating component 120 also has a better temperature storage effect and can further enhance the flavor of the aerosol. After the aerosol is drawn into the airflow channel 131, it flows along the airflow channel 131 with the vortex-shaped airflow, which can also achieve efficient heat dissipation of the aerosol, allowing the aerosol to be cooled and discharged, thus improving the user experience.

[0041] In this embodiment, the airflow channel 131 is vortex-shaped. Specifically, the airflow channel 131 has a spiral vortex shape in a cross-section perpendicular to the axial direction (e.g., Figure 3 (As shown). After the gas enters the airflow channel 131, there are two flow directions: one is axial flow and the other is axial flow. When outside air is drawn into the airflow channel 131 from the air inlet 111, it will first spiral around the axial direction under the guidance of the airflow channel 131, and gradually approach the vortex axis region 1312. When the airflow enters the vicinity of the vortex axis region 1312, it will flow axially under the action of external suction to be discharged outside the housing 110. When the gas forms a spiral vortex airflow under the guidance of the airflow channel 131, the vortex airflow will generate suction on the aerosol in the downstream aerosol generation component 120, drawing the aerosol into the airflow channel 131 and discharging it outside the housing 110 along with other gases. This allows the aerosol generation component 120 to discharge aerosol even when there is no new outside air flow. After the aerosol enters the airflow channel 131, it can first flow around the axis for a certain distance before flowing outward along the axis. During the process of the aerosol flowing around the axis, it can play a role in cooling the aerosol and achieve heat dissipation of the aerosol.

[0042] In this embodiment, the vortex axis region of the airflow channel 131 is part of the aerosol channel 1311, which is connected to the outlet end of the aerosol generating component 120. It can be understood that the aerosol channel 131 is a portion of the airflow channel 131 through which aerosols in the aerosol generating component 120 pass. The airflow velocity in the vortex axis region 1312 of the airflow channel 131 is relatively high, and the suction force is strong. By connecting the vortex axis region 1312 of the airflow channel 131 to the outlet end of the aerosol generating component 120, aerosols can be more easily drawn into the aerosol channel 1311, and the aerosols are discharged outwards through the aerosol channel 1311.

[0043] Understandably, the airflow channel 131 is at least aligned with the outlet of the aerosol generating component 120, with the region of the vortex axis 1312 aligned with the outlet of the aerosol generating component 120. In this embodiment, the outlet of the aerosol generating component 120 may also cover the portion outside the region of the vortex axis 1312, expanding the outlet of the aerosol to be discharged into the airflow channel 131. After entering the airflow channel 131, the aerosol may flow around the vortex axis 1312 for a certain distance before being discharged. When the aerosol flows around the vortex axis 1312, a cooling effect of the aerosol can be achieved.

[0044] In this embodiment, the airflow channel 131 is formed by a guide member 130, which is disposed inside the housing 110. The cross-section of the guide member 130 is spiral-shaped. Specifically, the cross-section of the guide member 130 is arranged in an Archimedean spiral pattern. It can be understood that the guide member 130 can be assembled inside the housing 110 or integrally formed inside the housing 110.

[0045] In one embodiment, the cross-section of the guide 130 is spiral, and the spacing between adjacent layers of the spiral cross-section gradually decreases from the outside to the inside. That is, the closer to the center of the spiral, the smaller the spacing between adjacent layers. The airflow channel 131 gradually narrows from the outside to the inside, so that the outside air is gradually compressed when it flows around the axis of the airflow channel 131 in a spiral. The compressed air can increase the absorption effect of aerosol.

[0046] In some embodiments, the flow guide 130 can be selected from sheets composed of metal foil, polymer sheets, and non-porous paper or cardboard. It can also be selected from sheets composed of any one of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil. After the aerosol enters the airflow channel 131, the flow guide can absorb the heat of the aerosol, thereby achieving a cooling output of the aerosol. In some embodiments, the flow guide 130 can also be made of a phase change material.

[0047] In this embodiment, the air inlet 111 is disposed on the side wall of the housing 110 and is correspondingly disposed with the guide 130. Specifically, the air inlet 111 and the guide 130 are located at the same horizontal height, which reduces the path of air from the air inlet 111 to the airflow channel 131 and improves the efficiency of forming vortex airflow.

[0048] In this embodiment, there are multiple air inlets 111. These multiple air inlets 111 can be arranged to surround the outer side of the housing 110, and / or arranged to be distributed along the axial direction of the housing 110. Multiple air inlets can improve the efficiency of air entering the airflow channel 131. It should be noted that "multiple" in this application specifically refers to a number greater than one.

[0049] In some embodiments, when multiple air inlets 111 are arranged to be distributed along the axial direction of the housing 110, the multiple air inlets 111 can be arranged to face the air inlet end 1313 of the airflow channel 131, that is, the multiple air inlets 111 are arranged to face the outermost opening of the guide member 130, thereby shortening the path of outside air into the airflow channel 131.

[0050] In some embodiments, when multiple air inlets 111 are arranged to be distributed along the axial direction of the housing 110, the spacing between adjacent air inlets 111 can be arranged to gradually increase from bottom to top along the axial direction, forming a denser arrangement at the bottom and a sparser arrangement at the top. This allows the lower air inlets 111 to have a larger air intake and the upper air inlets 111 to have a smaller air intake, thereby balancing the concentration and temperature of the aerosol and preventing the aerosol from being diluted due to excessive air intake, which would affect the user's taste.

[0051] In some other embodiments, the number of air inlets 111 may be set to one. When the number of air inlets 111 is set to one, the efficiency of air entering the airflow channel 131 can be improved by increasing the area of ​​the air inlet 111.

[0052] In this embodiment, the aerosol generation component 120 includes a heating element 121 and an aerosol generation substrate 122. The aerosol generation substrate 122 is in contact with the heating element 121, and the heating element 121 is used to heat the aerosol generation substrate 122 to form an aerosol.

[0053] In this embodiment, the heating element 121 is made of metal material. The heating element 121 generates heat through electromagnetic induction heating. The aerosol generating substrate 122 comes into contact with the heating element 121 and generates aerosol after receiving the heat from the heating element 121.

[0054] Of course, in other embodiments, to adapt to the heating methods of different products, the heating element 121 can also be composed of a tube made of ceramic or other materials with high thermal conductivity and a heating wire, with the heating wire attached to the inner wall of the tube or embedded inside the tube. After the heating wire is energized, it heats the ceramic tube, thereby achieving self-heating of the heating element 121.

[0055] Furthermore, in this embodiment, the heating element 121 is a tubular structure with an open top. The aerosol generating substrate 122 is in contact with the outer wall of the heating element 121, and the inner cavity of the heating element 121 is connected to the airflow channel 131 through the top opening of the heating element 121. In this embodiment, after the aerosol generating substrate 122 generates aerosol, as the amount of aerosol gradually increases, the aerosol will overflow into the inner cavity of the heating element 121. The inner cavity of the heating element 121 serves to store the aerosol and to concentrate and guide the outflow of the aerosol.

[0056] In this embodiment, the top opening of the heating element 121 connects with the airflow channel 131, allowing the inner cavity of the heating element 121 to communicate with the airflow channel 131 through the top opening. The vortex airflow formed in the airflow channel 131 can draw out the aerosol overflowing into the inner cavity of the heating element 121, thereby achieving natural aerosol intake. The tubular heating element 121 can collect and store the overflowing aerosol during the intervals when the user inhales the aerosol. When the aerosol is drawn out, it is more concentrated, resulting in a better taste. Moreover, this natural aerosol intake method ensures that the drawn-out aerosol is generated after the aerosol generating substrate 122 is fully heated, effectively reducing the output of harmful substances and protecting the health of consumers. It is understood that in this embodiment, the top opening of the heating element 121 is the air outlet of the aerosol generating component 120.

[0057] Furthermore, in order to enhance the guiding effect of the heating element 121 on aerosols, the heating element 121 can be configured as an inverted trumpet-shaped tube that is narrow at the top and wide at the bottom, or an inverted cone-shaped guide tube can be formed at the top of the heating element 121 so that the aerosols can be collected in the inner cavity of the heating element 121 and then enter the airflow channel 131.

[0058] In this embodiment, the heating element 121 and the aerosol generating substrate 122 are coaxially arranged. The heating element 121, which is coaxially arranged with the aerosol generating substrate 122, is centrally located within the aerosol generating substrate 122, ensuring uniform heating of the aerosol generating substrate 122.

[0059] In this embodiment, the heating element 121 and the flow guide 130 are coaxially arranged.

[0060] In this embodiment, the tubular heating element 121 has a circular cross-section. In other embodiments, the cross-section of the tubular heating element 121 may also be polygonal, triangular, cross-shaped, or star-shaped.

[0061] Of course, in some other embodiments, the heating element 121 can also be a sheet structure. The sheet structure heating element 121 contacts the aerosol generating substrate 122, causing the aerosol generating substrate 122 to generate aerosol. The aerosol can be extracted by directly overflowing from the aerosol generating substrate 122 into the airflow channel 131.

[0062] In this embodiment, the sidewall of the heating element 121 is provided with vent holes 1211, which communicate with the inner cavity of the heating element 121 and allow aerosols in the aerosol generation substrate 122 to pass through. Specifically, there are multiple vent holes 1211, which are arranged along the length of the heating element 121. These multiple vent holes 1211 are distributed on the sidewall of the heating element 121, allowing aerosols to enter the inner cavity of the heating element 121 through the vent holes 1211.

[0063] In this embodiment, the vent 1211 is a circular hole. Of course, in other embodiments, the vent 1211 can also be an elliptical hole, a triangular hole, a polygonal hole, or an irregularly shaped hole. Multiple vents 1211 can be uniformly formed using one of these shapes, and vents 1211 of different shapes can be combined onto a single heating element 121. The shape of the vent 1211 mentioned above specifically refers to the cross-sectional shape of the vent 1211.

[0064] Of course, in other embodiments, the heating element 121 can also be made of a breathable metal product, such as metal felt. When the heating element 121 is made of metal felt, due to the large porosity of the material of the heating element 121, the ventilation holes 1211 can be omitted from the side wall of the tubular heating element 121, and the aerosol can directly overflow into the inner cavity of the heating element 121 through the tube wall of the heating element 121.

[0065] In this embodiment, the aerosol generating substrate 122 and the airflow channel 131 are sealed together. Specifically, by sealing the aerosol generating substrate 122 and the airflow channel 131, the aerosol generating substrate 122 is isolated from the airflow channel 131, ensuring that the aerosol overflows into the inner cavity of the heating element 121 before entering the aerosol channel 1311. This achieves concentrated guidance of the aerosol, allowing it to be collected and then discharged outwards, thus improving the inhalation experience.

[0066] In this embodiment, a third air-blocking component 170 is provided between the aerosol generating substrate 122 and the airflow channel 131. The third air-blocking component 170 is connected around the outside of the heating element 121, and is used to isolate the top of the aerosol generating substrate 122 from the airflow channel 131. The third air-blocking component 170 enables the aerosol to flow along a preset trajectory: first overflowing from the aerosol generating substrate 122 into the inner cavity of the heating element 121, and then entering the airflow channel 131 from the inner cavity of the heating element 121.

[0067] In one embodiment, the aerosol generating article further includes a first gas-blocking component 140, which is disposed at the end of the aerosol generating assembly 120 away from the airflow channel 131. The first gas-blocking component 140 is used to isolate the aerosol generating assembly 120 from the outside environment. Specifically, in this embodiment, the first gas-blocking component 140 seals the end of the aerosol generating assembly 120 away from the airflow channel 131. The first gas-blocking component 140 is specifically disposed at the bottom end of the aerosol generating assembly 120. The first gas-blocking component 140 is used to seal the bottom end of the aerosol generating substrate 122 and the bottom end of the heating element 121. The airflow channel 131 is located at the top end of the heating element 121.

[0068] Of course, in other embodiments, the bottom of the housing 110 can be made into an integral sealed structure to isolate the bottom of the aerosol generating assembly 120 from the outside. This application does not specifically limit the sealing method of the end of the aerosol generating assembly 120 away from the aerosol channel 1311, as long as the end of the aerosol generating assembly 120 away from the aerosol channel 1311 is separated from the outside.

[0069] In one embodiment, the aerosol generating article further includes a filter 150 located downstream of the airflow channel 131. Specifically, under suction, the aerosol enters the filter 150 from the airflow channel 131. After large aerosol particles are filtered out by the filter 150, the aerosol is discharged. The filter 150 makes the discharged aerosol finer.

[0070] In this embodiment, the aerosol generating product further includes a second gas-blocking component 160, which is disposed between the airflow channel 131 and the filter 150. The second gas-blocking component 160 is provided with a connecting channel 161, which is connected to the airflow channel 131. The filter 150 is connected to the end of the connecting channel 161 away from the airflow channel 131.

[0071] In this embodiment, the connecting channel 161 is located downstream of the airflow channel 131 and is connected to the air outlet end of the aerosol channel 1311. The second air-blocking component 160 is used to block the airflow outside the vortex axis region of the airflow channel 131 from entering the filter 150, so that the airflow in the airflow channel 131 can flow along the flow trajectory enclosed by the guide component 130, thereby forming a vortex airflow. The connecting channel 161 of the second air-blocking component 160 is used to collect the aerosol and then flow it to the filter 150.

[0072] In this embodiment, the connecting channel 161 is funnel-shaped. Specifically, the diameter of the filter channel near the airflow channel 131 is smaller than the diameter of the end away from the airflow channel 131.

[0073] In some embodiments, the funnel-shaped connecting channel 161 can also be combined with the vortex formed by compressed air to improve the absorption effect of aerosols.

[0074] In this embodiment, the housing 110 is in the shape of a rod. The housing 110 can be made of paper or other insulating, non-magnetic, high-temperature resistant materials.

[0075] Based on the above-described aerosol-generating articles, this application also provides an aerosol-generating system, see reference. Figure 6 The aerosol generation system includes a housing 200, a power supply component 400, an induction coil 300, and an aerosol generation product as described in Embodiment 1. The power supply component 400 and the induction coil 300 are both disposed inside the housing 200. The power supply component 400 is electrically connected to the induction coil 300. The aerosol generation product can be inserted into the interior of the housing 200.

[0076] When the aerosol generating article is inserted into the housing 200, the induction coil 300 surrounds the outside of the aerosol generating component 120 of the aerosol generating article.

[0077] Compared with the prior art, the aerosol generation system provided in this application can carry out aerosols without the outside air passing through the aerosol generation component 120, avoiding the influence of the outside air on the heating temperature of the aerosol generation component 120. The aerosol generation component 120 can have a better temperature storage effect, allowing the heating temperature of the aerosol generation component 120 to be higher (up to 350°C), resulting in better atomization and further enhancing the flavor of the aerosol. Since the air inlet 111 is located on the side wall of the shell 110 of the aerosol generation product, the airflow no longer needs to enter the aerosol generation component 120 from the bottom of the shell 110 of the aerosol generation product before being discharged outward. The air inlet 111 can be located above the side wall of the shell 110 of the aerosol generation component 120, eliminating the need for an air intake channel inside the outer shell 200, which is beneficial for the miniaturization of the outer shell 200 of the aerosol generation system.

[0078] In this embodiment, the aerosol generation system also includes a bracket 500, which is disposed inside the housing 200. The bracket 500 has a slot, the shape of which is adapted to the shape of the aerosol generation product. The bracket 500 is used to support the aerosol generation product inserted into the housing 200.

[0079] In this embodiment, the aerosol generation system further includes a magnetic shielding plate 600, which is connected to the outer casing 200 and disposed between the induction coil 300 and the outer casing 200. The magnetic shielding plate 600 isolates the induction coil 300 from the outside environment, preventing the induction coil 300 from generating a magnetic attraction force on external objects during operation. The magnetic shielding plate 600 also prevents the induction coil 300 from being affected by external objects, allowing the magnetic field generated by the induction coil 300 to be more concentrated inside the aerosol generation system.

[0080] In this embodiment, the aerosol generation system further includes a charging circuit board 700.

1. An aerosol-generating product, characterized in that, include: Shell and aerosol generation components; The interior of the housing is provided with an airflow channel, and the side wall of the housing is provided with an air inlet. The airflow channel is connected to the outside atmosphere through the air inlet. The airflow channel is formed by a guide member, which is disposed inside the housing and has a spiral cross-section. The airflow channel is vortex-shaped, and the central region of the vortex axis of the airflow channel is an aerosol channel. The aerosol channel is connected to the air outlet of the aerosol generation component. The aerosol generating component is disposed inside the housing. The airflow channel is located downstream of the aerosol generating component. The airflow channel is used to allow outside air to enter the airflow channel under suction, and to form a vortex airflow downstream of the aerosol generating component. The vortex airflow makes the air pressure in the airflow channel lower than the air pressure in the aerosol generating component, thus creating a pressure difference between the airflow channel and the aerosol generating component. The vortex airflow draws out the aerosol in the aerosol generating component to remove the aerosol from the aerosol generating component. The end of the aerosol generating component away from the aerosol channel is sealed.

2. The aerosol-generating product according to claim 1, characterized in that, The aerosol generation assembly includes a heating element and an aerosol generation substrate, wherein the aerosol generation substrate is in contact with the heating element, and the heating element is used to heat the aerosol generation substrate to form an aerosol.

The second air-blocking component has a connecting channel that communicates with the airflow channel. The filter nozzle is connected to the end of the connecting channel away from the airflow channel. The second air-blocking component is used to block the airflow outside the vortex axis region of the airflow channel from entering the filter nozzle, so that the airflow in the airflow channel can flow according to the flow trajectory enclosed by the guide component, thereby forming a vortex airflow. The connecting channel of the second air-blocking component is used to collect the aerosol and then flow it to the filter nozzle.

9. An aerosol generation system, characterized in that, The device includes a housing, a power supply component, an induction coil, and an aerosol generating article as described in any one of claims 1-8, wherein the power supply component and the induction coil are both disposed within the housing, the power supply component is electrically connected to the induction coil, and the aerosol generating article can be inserted into the interior of the housing.
