Detailed description of the specific implementation

[0031] The present application will be further described in detail below in conjunction with the drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and general technical knowledge in the art.

[0032] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners, and the operation steps involved in each embodiment can also be reordered or adjusted in an obvious manner for those skilled in the art. Therefore, the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are essential components and / or sequences.

[0033] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "coupling" used in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

A small deviation is allowed, and being approximately parallel, approximately perpendicular, etc. are all acceptable. For example, when A is parallel to B, it means that A is parallel to B or approximately parallel to B, and the included angle between A and B can be between 0° and 10°.

[0035] Please refer to Figures 1-4 , the present application provides a heat-not-burn device. The heat-not-burn device includes a main body 10, a cartridge 20, and a heating assembly 30. The heat-not-burn device is used to heat an aerosol-generating article 40. Among them, the aerosol-generating article 40 may include a fuming matrix section, and the fuming matrix section may include a fuming matrix and a wrapper for wrapping the fuming matrix. The fuming matrix may include at least one of tobacco-based and non-tobacco-based fuming substances. For example, the non-tobacco fuming substance may include fibers adsorbed with glycerin and propylene glycol, etc. In addition, the fuming matrix may also include other components. The aerosol-generating article 40 may also be a solid fuming matrix block. Herein, the "solid fuming matrix block" means that the whole fuming matrix block is a formed body, rather than a loose form such as bulk particles, bulk filaments, or bulk flakes. For example, the fuming matrix block may be formed by extruding or stamping the fuming matrix to form a formed body with a certain air permeability. The fuming matrix block may be solidified from a mixture of tobacco or non-tobacco plants, as well as fuming agents, polysaccharides, etc. The aerosol-generating article 40 of the present application may omit structures such as a cooling section for cooling and a filter section for filtering in the existing aerosol-generating article 40.

[0036] The main body 10 is the main part of the heat-not-burn device. As Figure 2 shown, the main body 10 is provided with an installation space 11 and an air outlet channel 12. Among them, the installation space 11 may be formed by structures such as a groove and a notch. The installation space 11 is provided with an installation opening 111, and the installation opening 111 and the air outlet of the air outlet channel 12 face different sides of the main body 10 respectively. Different sides of the main body 10 may refer to the top side, the front side, the left side, the right side, the rear side, and the bottom side. For example, in Figure 2 the embodiment, the orientation of the installation opening 111 is perpendicular to the side surface of the main body 10, and the orientation of the air outlet of the air outlet channel 12 is perpendicular to the top surface of the main body 10.

[0037] The cartridge 20 is detachably or movably disposed within the installation space 11, and the cartridge 20 can be detached or moved through the installation opening 111. At least one receiving cavity 21 is provided within the cartridge 20 for receiving the aerosol-generating article 40. The shape of the receiving cavity 21 can be adapted to the shape of the aerosol-generating article 40. For example, in Figure 2 In an embodiment, the aerosol-generating article 40 is generally cylindrical, and the shape of the receiving cavity 21 is also cylindrical. In one embodiment, the receiving cavity 21 is provided with an opening 211 through which the aerosol-generating article 40 can be inserted into or withdrawn from the receiving cavity 21 to facilitate the user to replace the aerosol-generating article 40 within the cartridge 20.

[0038] The receiving cavity 21 has a working state and a standby state, and the cartridge 20 can drive the receiving cavity 21 to switch between the working state and the standby state. When the receiving cavity 21 is in the working state, the receiving cavity 21 communicates with the air outlet passage 12 so that the aerosol generated by the aerosol-generating article 40 can flow out through the air outlet passage 12 for the user to use. Specifically, the opening 211 of the receiving cavity 21 can be docked with the inlet end of the air outlet passage 12, and the opening 211 of the receiving cavity 21 can serve as the outlet for the aerosol to flow out of the receiving cavity 21. In one embodiment, in order for the aerosol generated by the aerosol-generating article 40 to flow out of the air outlet passage 12 more easily, the axis of the receiving cavity 21 is parallel to or on the same straight line as the axis of the air outlet passage 12.

[0039] In one embodiment, as Figure 4 shown, an air inlet passage 13 is provided within the main body 10, and the air inlet passage 13 communicates with the receiving cavity 21 in the working state. The air flow passes through the air inlet passage 13 to the receiving cavity 21, and after carrying the aerosol generated by the aerosol-generating article 40, it flows out through the air outlet passage 12. The inlet of the air inlet passage 13 can be provided on the bottom surface of the main body 10 or on other surfaces of the main body 10, such as the side surface or the top surface.

[0040] The standby state of the receiving cavity 21 means that the receiving cavity 21 in the cartridge 20 is not in communication with the air outlet passage 12. In the standby state, the receiving cavity 21 in the cartridge 20 can be disposed inside the installation space 11, or the receiving cavity 21 in the cartridge 20 can be driven by the cartridge 20 to be disposed outside the installation space 11, so that the user can replace the aerosol-generating article 40 that has been exhausted in the receiving cavity 21.

[0041] As Figure 2 shown, only one receiving cavity 21 can be provided within the cartridge 20, that is, the heat-not-burn device is a single cartridge. As Figure 5As shown, at least two receiving cavities 21 can also be provided in the cartridge 20, that is, the heat-not-burn device is multi-cartridge. When the heat-not-burn device is multi-cartridge, each receiving cavity 21 in the cartridge 20 can accommodate an aerosol-generating article 40. Therefore, at least two aerosol-generating articles 40 can be accommodated in the multi-cartridge cartridge 20.

[0042] When the heat-not-burn device is multi-cartridge, when the cartridge 20 is installed in the installation space 11, one of the receiving cavities 21 is in the working state, and the other receiving cavities 21 are in the standby state. After the aerosol-generating article 40 in the working state is exhausted, the receiving cavity 21 where the aerosol-generating article 40 in the standby state in the cartridge 20 moves to communicate with the air outlet channel 12, so as to switch to the working state, so that the heat-not-burn device can continue to be used. The multi-cartridge heat-not-burn device enables the user to not need to frequently replenish the aerosol-generating article 40 into the cartridge 20, and more aerosol-generating articles 40 can be replenished at one time. The cartridge 20 can be rotated or slid relative to the main body 10 and other movable ways to make different receiving cavities 21 communicate with the air outlet channel 12, so that different receiving cavities 21 are in the working state.

[0043] As Figures 2-4 shown, the heating component 30 is arranged in the cartridge 20 and configured to heat the aerosol-generating article 40 in the receiving cavity 21 in the working state, so as to generate aerosol from the aerosol-generating article 40. By arranging the heating component 30 in the cartridge 20, the heating component 30 is closer to the aerosol-generating article 40 in the cartridge 20, which is beneficial to improving the energy utilization rate of the heating component 30. The cartridge 20 can be configured with heat-insulating materials to prevent the heat in the cartridge 20 from being transferred to the main body 10. And in the multi-cartridge embodiment, arranging the heating component 30 in the cartridge 20 makes it easier to configure corresponding heating components 30 for different receiving cavities 21.

[0044] The heat-not-burn device of the present application is provided with a cartridge 20, and the cartridge 20 containing the aerosol-generating article 40 can be arranged in the installation space 11 of the main body 10. An air outlet channel 12 is arranged in the main body 10, and the air outlet channel 12 of the main body 10 communicates with the receiving cavity 21 where the aerosol-generating article 40 is located, so that the aerosol generated by the aerosol-generating article 40 can flow out of the heat-not-burn device through the air outlet channel 12 for the user to suck. Thus, the air outlet channel 12 of the main body 10 can replace the cooling section and the filter section of the aerosol-generating article 40 and be reused repeatedly. Therefore, the heat-not-burn device can be adapted to the aerosol-generating article 40 provided with only a matrix section. The single-section aerosol-generating article 40 can reduce the cost for the user to use the heat-not-burn device compared with the multi-section aerosol-generating article 40 as a consumable, and is beneficial to environmental protection.

[0045] As Figure 3 andFigure 4 As shown, in one embodiment, the heat-not-burn device further includes a power supply assembly 50, and the power supply assembly 50 includes a connecting electrode group 51. In addition, the power supply assembly 50 may further include a power supply 52 and a controller. The power supply 52 and the controller may be disposed inside the main body 10, and both the power supply 52 and the controller are electrically connected to the connecting electrode group 51.

[0046] As Figure 3 and Figure 6 shown, the heating assembly 30 includes at least one electrode portion 31 corresponding to the accommodation cavity 21. When the accommodation cavity 21 is in a working state, the corresponding electrode portion 31 is in electrical contact with the connecting electrode group 51. Among them, the electrode portion 31 may include at least two electrodes, for example, it may include a first electrode and a second electrode. The connecting electrode group 51 may also include at least two connecting electrodes, for example, it may include a first connecting electrode and a second connecting electrode. Specifically, the electrode portion 31 may protrude from the surface of the cartridge case 20 facing the connecting electrode group 51 to facilitate electrical contact with the connecting electrode group 51. As Figure 2 and Figure 5 shown, one of the connecting electrode group 51 and the electrode portion 31 may be an elastic conductive member, so that the electrode portion 31 of the accommodation cavity 21 in the working state can be in elastic contact with the connecting electrode group 51. The elastic conductive member can make the electrical connection between the electrode portion 31 and the connecting electrode group 51 more stable. For example, in the embodiments of Figure 2 and Figure 5 , the connecting electrode group 51 has a structure of a spring piece.

[0047] As Figure 3 shown, when there is one accommodation cavity 21 in the cartridge case 20, the number of heating assemblies 30 may be one. This heating assembly 30 is provided with one electrode portion 31, and the electrode portion 31 is in electrical contact with the connecting electrode group 51, so that the power supply 52 can supply power to the heating assembly 30, and the controller can control the heating parameters of the heating assembly 30.

[0048] Of course, when there is one accommodation cavity 21 in the cartridge case 20, the number of heating assemblies 30 may also be at least two. Different types of heating assemblies 30 (such as energy field heating, resistance heating, etc.) can be used to heat the accommodation cavity 21. Therefore, the number of connecting electrode groups 51 may also be at least two, and different connecting electrode groups 51 are electrically connected to the electrode portions 31 of the corresponding heating assemblies 30. The power supply assembly 50 can control each heating assembly 30 to work simultaneously, or can control a certain heating assembly 30 to work alone.

[0049] As Figure 6As shown, when there are at least two receiving cavities 21 in the cartridge case 20, each receiving cavity 21 corresponds to at least one heating component 30, and each heating component 30 is provided with an electrode portion 31. The connecting electrode group 51 can be in electrical contact with the electrode portion 31 of the heating component 30 corresponding to the receiving cavity 21 in the working state. When the cartridge case 20 drives the receiving cavity 21 to move to switch different receiving cavities 21 to the working state, the cartridge case 20 simultaneously drives the electrode portions 31 corresponding to different receiving cavities 21 to be in electrical contact with the connecting electrode group 51. For example, in Figure 5 and Figure 6 In the embodiment, the number of receiving cavities 21 is three, the number of heating components 30 is three, and the three heating components 30 respectively correspond to the three receiving cavities 21 one by one. Each heating component 30 is provided with an electrode portion 31, and the number of connecting electrode groups 51 is one. The connecting electrode group 51 can be electrically connected to the electrode portion 31 corresponding to the receiving cavity 21 in the working state. Among them, each receiving cavity 21 can adopt heating components 30 of different or the same types (such as energy field heating, resistance heating, etc.), and a certain receiving cavity 21 can adopt one or more types (such as energy field heating, resistance heating, etc.) of heating components 30.

[0050] Such as Figure 4 and Figure 7 As shown, in one embodiment, the heating component 30 includes at least one heating element 32 corresponding to the receiving cavity 21. The heating element 32 is exposed in the corresponding receiving cavity 21 and is configured to be in contact with and installed in the aerosol generating article 40 received in the receiving cavity 21, so that the heat of the heating element 32 can be transferred to the aerosol generating article 40. The electrode portion 31 corresponding to the receiving cavity 21 is electrically connected to the corresponding heating element 32. Among them, the heating element 32 may have a pin portion 321, and the pin portion 321 is in contact with the electrode portion 31 for electrical connection. The heating element 32 being exposed in the corresponding receiving cavity 21 may mean that the heating element 32 is disposed inside the receiving cavity 21 and can accommodate the aerosol generating article 40. For example, as Figure 4 shown, the heating element 32 may be a heating tube, and the heating tube is disposed in the receiving cavity 21 and is used to accommodate the aerosol generating article 40; or, the internal space of the heating element 32 forms the receiving cavity 21. In addition, the heating element 32 may also be in the form of a heating sheet, a heating wire, a heating mesh, etc. Or, as Figure 7 shown, the heating element 32 is disposed inside the receiving cavity 21 and can be inserted into the inside of the aerosol generating article 40. For example, in Figure 7 , the heating element 32 may be a heating needle, and the heating needle can be inserted into the inside of the aerosol generating article 40. The structure for heating the aerosol generating article 40 in the form of resistive contact heating is relatively simple, has a low cost, and the process is relatively mature.

[0051] Such as Figure 8As shown, in one embodiment, the heating assembly 30 includes at least one generator 33 corresponding to the accommodation cavity 21. The generator 33 is configured to generate an energy field applied to the corresponding accommodation cavity 21 for heating the aerosol generating article 40 inside the accommodation cavity 21. The energy field generated by the generator 33 is configured to be applied only to the working position. The electrode portion 31 corresponding to the accommodation cavity 21 is electrically connected to the corresponding generator 33, wherein, as Figure 10 shown, the generator 33 may have a contact leg 331, and the contact leg 331 contacts the electrode portion 31 for electrical connection. As Figure 12 , 13 shown, in the multi-cartridge embodiment, the number of accommodation cavities 21 is at least two, and the accommodation cavities 21 are spaced apart. A barrier layer may be provided between the accommodation cavities 21. The barrier layer is configured to block the energy or heat of the energy field so that when the energy field is applied to the working accommodation cavity 21, heat or energy leakage from the corresponding accommodation cavity 21 to the aerosol generating article 40 in the standby state can be prevented.

[0052] In one embodiment, the generator 33 may include one or more of an infrared generator, a microwave generator, an ultrasonic generator, and an electromagnetic field generator. By configuring the heating assembly 30 as a generator 33 capable of generating an energy field, the heating assembly 30 can remotely heat the aerosol generating article 40 in the accommodation cavity 21 in a non-contact manner. Moreover, in radiation heating methods such as infrared radiation and microwave radiation, different from heat transfer heating, heat transfer in heat transfer heating takes a certain amount of time, which may result in uneven heating of various parts of the aerosol generating article 40. However, some energy fields can penetrate the aerosol generating article 40 and cause the aerosol generating article 40 to generate heat, enabling more uniform heating of various parts of the aerosol generating article 40.

[0053] In one embodiment, the generator 33 includes an infrared generator. The infrared generator can generate an infrared radiation field. The infrared generator can be a heating element capable of quickly generating heat and generating infrared rays, such as a quartz tube heating element, a ceramic heating element, a tungsten halogen lamp, an iodine tungsten lamp, etc. When the frequency of the incident infrared rays is equal to the natural frequency of the fuming matrix, resonance is likely to occur, which can first cause the vibration and rotation of the molecules and atoms of the fuming matrix, and then increase the amplitude of the movement of the fuming matrix molecules, thereby generating heat.

[0054] In one embodiment, the generator 33 includes a microwave generator that can generate a microwave radiation field. The microwave radiation can cause the temperature of the aerosol-forming substrate to rise by generating "internal frictional heat" through the high-frequency reciprocating motion of the dipole molecules inside the aerosol-forming substrate. Without any heat conduction process, the inside and outside of the aerosol-forming substrate can be heated and raised in temperature simultaneously, with a fast and uniform heating rate. Only a fraction or a few tenths of the energy consumption of traditional heating methods is required to achieve the heating purpose. In some embodiments, the microwave radiation generated by the microwave generator is directed towards the receiving cavity 21, and the cartridge case 20 between the microwave generator and the receiving cavity 21 has a transmissive portion through which the microwave radiation can pass.

[0055] In one embodiment, as Figure 8 shown, the heat-not-burn device further includes a reflection assembly 60. The reflection assembly 60 is disposed in the cartridge case 20 and on the periphery of the receiving cavity 21. The reflection assembly 60 is used to reflect and converge the energy field generated by the generator 33 to the receiving cavity 21 to improve the utilization efficiency of the energy field. In the multi-cartridge embodiment, each receiving cavity 21 can be configured with a set of the generator 33 and the reflection assembly 60. The reflection assembly 60 is used to reflect the energy field of the corresponding generator 33 to the corresponding receiving cavity 21. The reflection assembly 60 is generally applicable to heating methods such as microwave or infrared. The reflection assembly 60 can be, for example, made of metal, heat-insulating material with a metal coating, a mirror, etc., and the reflecting surface of the reflection assembly 60 can be provided with protrusions or depressions to increase the area of the reflecting surface.

[0056] In one embodiment, the generator 33 includes an ultrasonic generator that generates ultrasonic waves. When the ultrasonic waves pass through the aerosol-generating article 40, heat may be generated in the aerosol-generating article 40 under the combined action of mechanical friction, acoustic heating effect, and cavitation effect.

[0057] As Figures 9-13 shown, in one embodiment, the generator 33 includes an electromagnetic field generator that can generate an electromagnetic wave radiation field. Induction heating is a method of heating using eddy currents generated by an alternating magnetic field. For example, in one embodiment, the generator 33 includes at least one induction coil 332 corresponding to the receiving cavity 21, and the energy field is the alternating magnetic field generated by the induction coil 332.

[0058] The heat-not-burn device further includes at least one induction heating element corresponding to the receiving cavity 21, and the induction heating element generates heat in response to the corresponding energy field to contact and heat the aerosol-generating product 40 located in the corresponding receiving cavity 21. In one embodiment, the induction heating element includes a magnetic induction heating tube, which is made of a magnetic induction material and is disposed in the receiving cavity 21. The magnetic induction heating tube can be used to accommodate the aerosol-generating product 40, and the magnetic induction heating tube can induce an alternating magnetic field to generate heat to heat the aerosol-generating product 40 in the magnetic induction heating tube. In another embodiment, the induction heating element includes a magnetic induction needle, which is configured to be inserted into the aerosol-generating product 40 when the aerosol-generating product 40 is installed in the receiving cavity 21, so as to heat the aerosol-generating product 40.
