Description

Technical Field

[0001] The present application relates to the field of aerosol generation technology, and in particular, to an aerosol generating product and an aerosol generating system. Background Art

[0002] Aerosol-generating products can generate aerosols only when baked and heated, and can effectively reduce the generation of harmful substances compared to traditional combustion products.

[0003] Aerosol-generating products are typically inserted into the receiving cavity of a heat-not-burn device for user use. When conventional aerosol-generating products are inserted into a receiving cavity containing a central heating element, the substrate segments of the products are squeezed and damaged by the insertion of the central heating element. This results in the substrate in contact with the central heating element adhering to the surface of the central heating element when the aerosol-generating product is removed, and the substrate may fall out and remain in the receiving cavity. Therefore, before the next use of the heat-not-burn device, the user must clean the receiving cavity and the central heating element. Utility Model Content

DETAILED DESCRIPTION

[0051] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0053] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0054] See also Figure 1-2 As shown, the present application provides an aerosol generating article 100, which generates aerosol under the action of heating and baking. Figure 1The dotted line with an arrow in the middle represents the movement path of the airflow during suction. Figure 1 and Figure 2 The horizontal line in the figure is the dividing line between the matrix segment and the functional segment.

[0055] Furthermore, the aerosol-generating article 100 includes a substrate segment 10 and a functional segment 20. The functional segment 20 is connected to the substrate segment 10. The substrate segment 10 houses an aerosol-generating substrate 11. The aerosol-generating substrate 11 generates the aerosol under the action of heating and baking, and flows out of the aerosol-generating article 100 through the functional segment 20.

[0056] Furthermore, the matrix segment 10 is structured to have a central hole 12 and a receiving chamber 13 that are separated from each other. The receiving chamber 13 is arranged around the central hole 12. The central hole 12 is used to receive the central heating element, and the receiving chamber 13 receives the aerosol generating matrix 11.

[0057] Furthermore, when the aerosol-generating article 100 is inserted along the substrate segment 10 into the receiving cavity of a heat-not-burn device, the central heating element within the receiving cavity will be inserted into the central hole 12, thereby preventing the central heating element from damaging the structure of the receiving chamber 13 and, consequently, from directly contacting the aerosol-generating substrate 11 within the receiving chamber 13. This prevents the aerosol-generating substrate 11 from adhering to the central heating element or falling into the receiving cavity when the aerosol-generating article 100 is removed from the receiving cavity. Thus, the heat-not-burn device can be used directly when the user reuses it.

[0058] Furthermore, the functional section 20 is constructed with a separate airflow channel 21 and an air intake chamber 22. The air intake chamber 22 is arranged around the airflow channel 21, and the airflow channel 21 is connected to the central hole 12, and the air intake chamber 22 is connected to the receiving chamber 13. The outer wall of the air intake chamber 22 is provided with an air intake hole 43.

[0059] Furthermore, air can pass between the central hole 12 and the receiving chamber 13 , so that aerosol generated in the receiving chamber 13 can enter the central hole 12 and move toward the airflow channel 21 .

[0060] During inhalation, at least a portion of the external air enters the air inlet chamber 22 through the air inlet hole 43, mixes with the formed aerosol in the receiving chamber 13, enters the central hole 12, and flows out of the central hole 12 toward the air flow channel for inhalation by the user. By providing the air inlet hole 43 on the outer wall of the air inlet chamber 22, the external air can cool the functional section 20 when entering the air inlet chamber 22, thereby preventing the user from burning their mouth when inhaling through the functional section 20.

[0061] Please continue reading Figure 1-2 As shown, the aerosol-generating article 100 includes an inner cover layer 30 , an outer cover layer 40 , a first end-sealing layer 50 and a second end-sealing layer 60 .

[0062] The inner covering layer 30 is configured to form the interconnected central hole 12 and the air flow channel 21. In some embodiments, the inner covering layer 30 can be formed by winding and enclosing to form the central hole 12 and the air flow channel 21. The central hole 12 and the air flow channel 21 are coaxially arranged and have the same diameter.

[0063] The outer covering layer 40 is disposed around the outer periphery of the inner covering layer 30, and the outer covering layer 40 and the inner covering layer 30 define a first opening 41 and a second opening 42 that are oppositely disposed. The first opening 41 is located outside the airflow channel 21 away from the central hole 12 and communicates with the air inlet chamber 22. The second opening 42 is located outside the central hole 12 away from the airflow channel 21 and communicates with the receiving chamber 13.

[0064] Furthermore, the first end-sealing layer 50 is closed at the first opening 41 , and the first end-sealing layer 50 , the inner cladding layer 30 , and the outer cladding layer 40 define and form the air inlet chamber 22 .

[0065] The second end-sealing layer 60 closes the second opening 42, and the second end-sealing layer 60, the inner cladding layer 30, and the outer cladding layer 40 define the receiving chamber 13. In some embodiments, the second end-sealing layer 60 may also close the opening of the central hole 12 away from the air flow channel 21.

[0066] Furthermore, the air inlet holes 43 are provided on the outer covering layer 40. In some embodiments, the air inlet holes 43 are arranged at intervals along the circumference of the outer covering layer 40 so that the external air enters the air inlet chamber 22 evenly.

[0067] Furthermore, the inner covering layer 30 and the outer covering layer 40 can be made of materials such as pure hemp fiber high-temperature resistant paper, hemp fiber-containing high-temperature resistant paper (hemp fiber mixed with a small amount of wood pulp fiber), aluminum foil composite paper (one side is aluminum foil and the other side is pure hemp or hemp fiber-containing paper), carbon fiber tube, glass fiber tube, perforated thin-walled metal tube, etc.

[0068] Furthermore, the inner covering layer 30 includes a first section 31 and a second section 32 connected to each other. The first section 31 is configured to form the air flow channel 21, and the second section 32 is configured to form the central hole 12.

[0069] The outer covering layer 40 includes a third section 44 and a fourth section 45 that are connected to each other. The third section 44 is disposed around the outside of the first section 31 and, together with the first section 31 and the first end-sealing layer 50, defines the air inlet chamber 22. The fourth section 45 is disposed around the outside of the second section 32 and, together with the second section 32 and the second end-sealing layer 60, defines the receiving chamber 13.

[0070] Furthermore, the first section 31 is not air-permeable, while the second section 32 is air-permeable; or the first section 31 is poorly air-permeable, while the second section 32 is significantly more air-permeable than the first section 31. Under the action of suction, the air entering the air inlet chamber 22 first passes through the receiving chamber 13, mixes with the formed aerosol in the receiving chamber 13, then passes through the second section 32 to enter the central hole 12, and then flows out of the air flow channel 21 for inhalation by the user.

[0071] In a first embodiment, the inner coating 30 is made of a breathable material. To prevent gas within the air inlet chamber 22 from directly entering the airflow channel 21 through the first section 31, the first section 31 may be covered with a sealing layer to prevent the first section 31 from being breathable. Alternatively, the first section 31 may be coated with a volatile coating, such as solid flavoring, gelatin, beeswax, modified chitosan, glyceride, glycerol gel, etc. During use, the central heating element directly heats the second section 32, while the first section 31 is heated solely by heat transfer and aerosol flow. Consequently, the temperature of the second section 32 drops significantly higher than that of the first section 31, causing the coating on the second section 32 to evaporate rapidly, thereby rendering the second section 32 breathable.

[0072] In the second embodiment, the inner covering layer 30 is made of an airtight material. To ensure that the aerosol generated in the receiving chamber 13 can enter the central hole 12 from the second section 32 , a plurality of air holes can be evenly opened on the second section 32 .

[0073] Further, see Figure 3-7 As shown, the aerosol generating article 100 further comprises a support structure which supports the functional section 20 so that the air inlet chamber 22 of the functional section 20 can ensure smooth entry of external air and the air flow channel 21 can ensure smooth flow of aerosol.

[0074] Further, see Figure 3-4 As shown, in the first embodiment, the supporting structure is a breathable filling material 71, and the breathable filling material 71 is filled in the air intake bin 22, so that the air intake bin 22 is effectively supported by the filling.

[0075] Furthermore, the breathable filling material 71 can be acetate fiber, hemp fiber, pre-oxidized silk, carbon fiber, metal aluminum fiber, or a mixture of the above fibers; it can also be porous graphite, cordierite porous material, mullite porous material, metal ceramic porous material, or a mixture of the above materials loaded with phase change material (not limited to polylactic acid, high-temperature paraffin particles).

[0076] See also Figure 3 As shown, in one embodiment, the breathable filling material 71 is at least partially in contact with the inner cover layer 30 and the outer cover layer 40. For example, the breathable filling material 71 is spaced a certain distance from the end of the receiving bin 13 away from the second opening 42; or, the breathable filling material 71 is spaced a certain distance from the first opening 41; or, the filling material is spaced a certain distance from both the second opening and the end of the receiving bin 13 away from the second opening 42.

[0077] See also Figure 4 As shown, in another embodiment, the breathable filling material 71 fills the air inlet bin 22 .

[0078] By providing the breathable filling material 71 , the speed at which the aerosol in the receiving chamber 13 moves toward the air inlet chamber 22 can be effectively reduced, so that the aerosol in the receiving chamber 13 can more fully pass through the second section 32 and enter the central hole 12 .

[0079] See also Figure 5 As shown, in the second embodiment, the support structure is supported within the air intake chamber 22. The support structure includes a first support portion 721, a second support portion 722, and a connecting portion 723. The connecting portion 723 is connected between the first support portion 721 and the second support portion 722, and the first support portion 721 abuts the inner cladding layer 30, while the second support portion 722 abuts the outer cladding layer 40.

[0080] In this embodiment, the support structure is made of a hard material. For example, the support structure can be a metal sheet, food-grade hard plastic, etc. The metal sheet can be copper foil, copper foil with an oxidation coating (copper foil surface plated with silver or gold or coated with a dense oxide layer), multi-layer laminated metal foil (with an interlayer of copper foil and an outer layer of aluminum foil, stainless steel foil, or silver foil), aluminum foil, aluminum bronze foil, titanium-aluminum composite foil, titanium foil, etc.

[0081] By providing the support structure, not only can the functional section 20 be effectively supported to ensure the normal use of the air inlet bin 22 and the air flow channel 21, but the support structure can also be used to absorb the heat on the first section 31, thereby cooling the functional section 20 and conducting this part of the heat to the air inlet bin 22 to preheat the air entering the air inlet bin 22, thereby improving the heating efficiency of the aerosol generating matrix 11 in the receiving bin 13, so as to avoid burning the mouth when the user inhales.

[0082] Furthermore, in one embodiment, the first support portion 721 may be wrapped around the outer peripheral side of the first section 31, so that while supporting the air inlet bin 22, it can also seal the first section 31, thereby preventing the aerosol entering the air inlet bin 22 from directly entering the air flow channel 21 from the first section 31.

[0083] Furthermore, the second support portion 722 is provided with an air guide hole 7221 , and the air guide hole 7221 is connected between the air inlet hole 43 and the air inlet bin 22 . External air passing through the air inlet hole 43 will enter the air inlet bin 22 through the air guide hole 7221 .

[0084] Furthermore, the connecting portion 723 is located in the air inlet chamber 22 and is spaced a certain distance from the first opening 41. The first supporting portion 721 extends from the connecting portion 723 toward the matrix segment 10 and abuts against and covers the outer periphery of the inner cladding layer 30.

[0085] Preferably, in this embodiment, the first supporting portion 721 abuts against and covers the outer circumference of the first section 31 .

[0086] Furthermore, in one embodiment, the first support portion 721 abuts against the inner cladding layer 30 and is located in the air inlet bin 22 , so that the support structure is located in the air inlet bin 22 .

[0087] In another embodiment, the first support portion 721 abuts against the inner cladding layer 30 and is located in the air flow channel 21 , so that the first support portion 721 can more efficiently absorb the heat in the air flow channel 21 and transfer it to the air inlet chamber 22 .

[0088] See also Figure 6 As shown, in the third embodiment, the support structure includes a breathable filling material 71 and a heat conductor 73. The breathable filling material 71 is filled in the air inlet bin 22 and is at least partially in contact with the inner cladding layer 30 and the outer cladding layer 40. The heat conductor 73 is disposed through the first section 31 and is at least partially located in the air flow channel 21 and at least partially located in the air inlet bin 22.

[0089] Furthermore, the heat conducting member 73 includes a first heat conducting portion 731, a second heat conducting portion 732, and a third heat conducting portion 733. The second heat conducting portion 732 passes through the inner cladding layer 30 and is connected between the first heat conducting portion 731 and the third heat conducting portion 733. The first heat conducting portion 731 is located in the air flow channel 21, and the third heat conducting portion 733 is located in the air inlet chamber 22 and contacts the breathable filling material 71.

[0090] In this embodiment, the heat in the air flow channel 21 is conducted to the breathable filling material 71 located in the air inlet bin 22 through the heat conductor 73, so that the heat that is penetrated will heat the breathable filling material 71, and then the air flowing through the breathable filling material 71 is preheated, so as to make full use of the heat emitted by the central heating element to efficiently heat the aerosol generating matrix 11.

[0091] See also Figure 7 As shown, in the fourth embodiment, the support structure includes a breathable filling material 71 and a heat-conducting and water-permeable member 74. The breathable filling material 71 is filled in the air inlet bin 22 and is at least partially in contact with the inner cladding layer 30 and the outer cladding layer 40. The heat-conducting and water-permeable member 74 is embedded in the first section 31 and is at least partially located in the air flow channel 21 and at least partially located in the air inlet bin 22.

[0092] Furthermore, the heat-conducting and water-permeable member 74 is provided between the air flow channel 21 and the air inlet bin 22 , and the inner surface of the heat-conducting and water-permeable member 74 is located in the air flow channel 21 , and the outer surface of the heat-conducting and water-permeable member 74 is in contact with the breathable filling material 71 .

[0093] Furthermore, the heat-conductive and water-permeable component 74 includes a heat-conductive layer 741 and a water-permeable hole 742 provided on the heat-conductive layer 741. The heat-conductive layer 741 is embedded in the first section 31. In the process of the heat-conductive layer 741 absorbing the heat in the air flow channel 21 and conducting it to the breathable filling material 71, condensed water will be generated in the air flow channel 21. The generated condensed water will flow toward the center hole 12 and pass through the heat-conductive layer 741 into the air inlet bin 22 when flowing through the water-permeable hole 742, thereby preventing the condensed water from directly sliding into the receiving cavity of the heating without combustion device.

[0094] In some embodiments, a water-absorbing material, such as absorbent cotton, may be embedded in the water-permeable hole 742 to allow the condensed water on the inner wall of the air flow channel 21 to smoothly pass through the heat-conducting layer 741 and enter the air inlet bin 22 .

[0095] Further, see Figure 8-12 As shown, the functional section 20 includes a filter layer 23, which is filled at least within the air flow channel 21 and is used to filter the aerosol. The filter layer 23 can be made of acetate fiber or a fiber material containing zeolite or activated carbon.

[0096] See also Figure 8 As shown, in the first embodiment, the filter layer 23 is only filled in the air flow channel 21 and is close to the first opening 41 .

[0097] Furthermore, a partition layer 14 is provided within the airflow channel 21, and is disposed radially along the airflow channel 21 and adjacent to the first opening 41. The filter layer 23 is received within the airflow channel 21 and abuts against a side of the partition layer 14 away from the central hole 12, and the partition layer 14 is provided with an air hole 141.

[0098] See also Figure 9-12 As shown, in a second embodiment, the filter layer 23 is located at the end of the functional segment 20 away from the matrix segment 10. The filter layer 23 includes a first portion 231 and a second portion 232. The second portion 232 is disposed around the first portion 231. The first portion 231 fills the airflow channel 21, while the second portion 232 fills the air inlet chamber 22, forming the first end-capping layer 50.

[0099] Further, in one embodiment, please refer to Figure 13As shown, a waterproof, breathable layer 80 is provided within the air inlet chamber 22. The waterproof, breathable layer 80 divides the air inlet chamber 22 into a first chamber 221 and a second chamber 222. The first chamber 221 communicates with the air inlet hole 43, and the second chamber 222 communicates with the receiving chamber 13. Aerosol moving from the receiving chamber 13 to the second chamber 222 can directly pass through the first section 31 into the airflow channel 21 and flow outward within the airflow channel 21 away from the central hole 12.

[0100] The condensed water entering the first chamber 221 from the air flow channel 21 will be collected in the first chamber 221 under the obstruction of the waterproof and breathable layer 80. This prevents the collected condensed water from entering the receiving chamber 13 and causing the aerosol generating substrate 11 to become damp, thereby affecting the heating efficiency and use effect.

[0101] In addition, by providing the waterproof and breathable layer 80, when the aerosol generating product 100 is not in use, it is possible to prevent water vapor carried in the air entering the air inlet chamber 22 through the air inlet hole 43 from entering the receiving chamber 13, causing the aerosol generating matrix 11 in the receiving chamber 13 to become damp.

[0102] Furthermore, before the aerosol-generating article 100 is used, the air inlet 43 is hidden on the outer covering layer 40 and isolates the air inlet chamber 22 from the outside world, so as to prevent the outside air carrying water vapor from entering the air inlet chamber 22 and moving into the receiving chamber 13, thereby causing the aerosol-generating article 100 in the receiving chamber 13 to become damp.

[0103] In the first embodiment, a puncture member is provided in the air inlet chamber 22. During suction, the outer covering layer 40 moves toward the puncture member due to negative pressure and is punctured by the puncture member to form the air inlet hole 43.

[0104] In a second embodiment, a puncture element is provided within the air inlet chamber 22. Before inhalation, the outer covering layer 40 moves toward the puncture element under the pressure of an external force and is punctured by the puncture element, thereby forming the air inlet hole 43. In this embodiment, before inhalation, the user can hold the matrix segment 10 and press the outer covering layer 40 in the area where the puncture element is located, thereby puncturing the outer covering layer 40 and forming the air inlet hole 43.

[0105] In the third embodiment, the outer cover layer 40 has a weak area. When suction is applied, the weak area ruptures due to negative pressure to form the air inlet 43.

[0106] On the other hand, the present application also provides an aerosol-generating system, comprising the aforementioned aerosol-generating article 100. Therefore, the aerosol-generating system also possesses all the technical effects of the aerosol-generating article 100. The aerosol-generating system further comprises a central heating element, which is configured to be inserted into the central hole 12 and heat the aerosol-generating substrate 11 contained in the containing chamber 13.

[0107] Since the technical effects of the aerosol generating product have been described in detail above, they will not be repeated here.

[0108] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0109] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0110] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
