[0029] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar reference numerals. 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 the general technical knowledge in the art.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to 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.

[0031] The serial numbers assigned to the components in this text, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0032] The heat-not-burn device generally consists of a main body and a carrier. Among them, the carrier is fixedly installed on the main body. An insertion cavity is provided on the carrier, and an installation channel communicating with the insertion cavity is also provided on the main body. A heating element is provided inside the insertion cavity. Inserting the aerosol-generating substrate into the insertion cavity through the installation channel can make the heating element insert into the aerosol-generating substrate. As Figure 1 shown, the aerosol-generating substrate 1 generally consists of a filter section 2, a cooling section 3, and a substrate section 4. After the aerosol-generating substrate is inserted into the insertion cavity, the heating element inserts into the substrate section 4. The substrate section 4 is formed by smoking materials such as tobacco and a smoking agent. The substrate section 4 is heated by the heating element, so that the volatile compounds in the substrate section generate aerosol. The aerosol is cooled by the cooling section 3 and filtered by the filter section 2 before being inhaled by the user.

[0033] When replacing the aerosol-generating substrate, it is necessary to remove the aerosol-generating substrate originally inserted into the insertion cavity. During the removal process, residues such as debris generated after heating of the substrate section will remain in the insertion cavity under the action of the heating element. Due to the narrow and long space of the insertion cavity, it is difficult to clean the residues.

[0034] See Figures 2 - 6 shown, the heat-not-burn device provided in this application includes a main body 10 and a carrier 20.

[0035] A notch 11 is provided on one side of the main body 10. An air intake channel 12 and an air outlet channel 13 are provided inside the main body 10. Both the air intake channel 12 and the air outlet channel 13 communicate with the notch 11.

[0036] In this embodiment, the intake channel 12 allows external air to enter, and the outlet channel 13 allows the aerosol to be output along with the airflow generated by the entering external air. The intake channel 12 has a first inlet 121 and a first outlet 122, and the outlet channel 13 has a second inlet 131 and a second outlet 132. Among them, the first outlet 122 is one end of the intake channel 12 facing the notch 11, and the second inlet 131 is one end of the outlet channel 13 facing the notch 11. The first inlet 121 is the inlet for external air to enter, and the first outlet 122 is the outlet for the external air to enter the aerosol generating matrix 100 after entering. After the external air passes through the first outlet 122, it enters the aerosol generating matrix through the second inlet 131, and the generated aerosol flows out from the second outlet 132.

[0037] The carrier 20 is detachably installed in the notch 11. In a specific embodiment, the carrier 20 can be installed in the notch 11 in a sliding, rotating or other ways.

[0038] The carrier 20 is provided with a receiving cavity 21 for receiving the aerosol generating matrix 100 without a filter section. Usually, the aerosol generating matrix is composed of a filter section, a cooling section and a matrix section. In this application, the aerosol generating matrix without a filter section is adopted, which can achieve the purpose of saving material costs.

[0039] In one embodiment, the aerosol generating matrix 100 without a matrix section can be only a matrix section or a matrix section including a cooling section, which is specifically selected according to actual needs and is not limited herein.

[0040] Among them, the matrix section can include tobacco or non-tobacco plants, can also include a smoke generator, and can also add or mix materials with fragrance enhancement to enrich the smell of the generated aerosol.

[0041] Of course, it is not difficult to understand that fragrance enhancement materials with different scents can be added or mixed into different aerosol generating matrices 100 to meet the usage requirements of different users.

[0042] In this embodiment, a first air through hole 22 is provided at the bottom of the receiving cavity 21. After the carrier 20 is loaded into the notch 11, the first air through hole 22 can communicate with one end of the intake channel 12 facing the notch 11, and the opening 211 of the receiving cavity 21 can communicate with the outlet channel 13. Specifically, after the carrier 20 is loaded into the notch 11, the first air through hole 22 communicates with the first outlet 122 of the intake channel 12, and the opening 211 of the receiving cavity 21 communicates with the second inlet 131 of the outlet channel 13.

[0043] A suction nozzle 14 is further provided on the main body 10. The suction nozzle 14 has a suction nozzle channel 141, and the suction nozzle channel 141 communicates with the air outlet channel 13. In one embodiment, the suction nozzle 14 is detachably or fixedly connected to the main body 10. In actual use, after the carrier 20 loaded with the aerosol generating matrix 100 without a filter section in the accommodation cavity 21 is installed into the notch 11, the user sucks through the suction nozzle 14. Through the suction nozzle channel 141, the air outlet channel 13, and the aerosol generating matrix 100, a negative pressure is generated in the air inlet channel 12, so that external air enters the air inlet channel 12 through the first inlet 121 of the air inlet channel 12 and forms an air flow. The air flow flows through the aerosol generating matrix 100, and the aerosol generated by the aerosol generating matrix 100 is output through the air outlet channel 13 and the suction nozzle channel 141 for the user to use.

[0044] In the heat-not-burn device provided by the present application, after the aerosol generating matrix 100 is used up, the carrier 20 can be detached from the notch 11 of the main body 10, and the consumed aerosol generating matrix can be removed. If there are residues remaining in the accommodation cavity after the aerosol generating matrix is removed, tools can be used to clean the residues. Compared with the conventional method in which the carrier 20 is integrally integrated inside the main body 10, the heat-not-burn device of the present application can facilitate the cleaning of the residues in the accommodation cavity 21 and is convenient for the user to operate.

[0045] To heat the aerosol generating matrix 100, as shown in Figure 3 and Figure 4 shown, the heat-not-burn device provided in this embodiment further includes a heating component 30, and the heating component 30 is used to heat the aerosol generating matrix 100 in the accommodation cavity 21 of the carrier 20. As shown in Figure 3 shown, the heating component 30 is disposed inside the carrier 20 and around the accommodation cavity 21.

[0046] As shown in Figure 3 shown, the heating component 30 may include a heating element 31 having a needle-shaped, rod-shaped or columnar structure, such as a contact heating body or a non-contact heating body. Exemplarily, the heating component 30 is a contact heating body. The heating element 31 is disposed at the notch 11 of the main body 10 and partially extends into the notch 11. Correspondingly, an insertion port is provided on the carrier 20, and the insertion port is arranged around the accommodation cavity 21 of the carrier 20. After the carrier 20 is installed into the notch 11, the part of the heating element 31 extending into the notch 11 is inserted into the insertion port, so that the heating element 31 can heat the accommodation cavity 21, and the heat generated by the heating is conducted to the aerosol generating matrix 100 through the accommodation cavity 21.

[0047] In this embodiment, the heating element 31 is a heating structure that can generate heat under the action of electric energy, such as a heating wire or a heating structure provided with a heating wire. An energy supply unit 15 is further provided inside the main body 10, and the energy supply unit 15 is electrically connected to the heating element 31 of the heating assembly 30 to supply electric energy to the heating element 31.

[0048] The energy supply unit 15 can be a rechargeable battery to facilitate the use of this heat-not-burn device.

[0049] In some embodiments, the aerosol generating substrate 100 can also be heated by a hot air flow. Refer to Figure 4 As shown, the heating assembly 30 is disposed in the intake passage 12 and can form a high-temperature air flow for the external air entering through the intake passage 12. Specifically, the high-temperature air generated after heating the heating assembly 31 can enter the accommodation cavity 21 from the first through hole 22 to heat the aerosol generating substrate 100 in the accommodation cavity 21.

[0050] The heating assembly 30 disposed in the intake passage 12 can be a honeycomb ceramic heating element or a metal heating resistance wire, etc., as long as it can quickly heat the entering external air.

[0051] When heating the aerosol generating substrate 100 with a high-temperature air flow, to ensure uniform heating, continue to refer to Figure 4 As shown, in this embodiment, the carrier 20 includes an inner cylinder 23, an outer cylinder 24, and a sandwich space 25 formed between the inner cylinder 23 and the outer cylinder 24. An accommodation cavity 21 is formed inside the inner cylinder 23. The bottom of the inner cylinder 23 is suspended inside the outer cylinder 24, and a first through hole 22 is formed at the bottom of the inner cylinder 23. The outer cylinder 24 is provided with an air inlet 241 communicating the sandwich space 25 with the intake passage 12. The air flow heated by the heating assembly 30 enters the sandwich space 25 through the air inlet 241 and enters the accommodation cavity 21 through the first through hole 22. Since the sandwich space 24 surrounds the accommodation cavity 21, circumferential heating of the accommodation cavity 21 can be realized to uniformly heat the aerosol generating substrate 100.

[0052] In this embodiment, a plurality of second air through holes 231 are provided at intervals in the circumferential direction on the side wall of the inner cylinder 23, and the second air through holes 231 are provided on the side of the inner cylinder 23 away from the cavity opening 211. In one embodiment, the gas flow rate entering from each of the second air through holes 231 is less than the gas flow rate entering from the first air through hole 22, so that the first air through hole 22 is the main air inlet channel, and the second air through hole 231 is the auxiliary air inlet channel. The second air through hole 231 is used for auxiliary heating. For example, the aperture of the second air through hole 231 can be smaller than that of the first air through hole 22. Since a part of the hot air flows into the aerosol generating matrix 100 from bottom to top through the first air through hole 22, and another part of the hot air radially enters the aerosol generating matrix 100 through the second air through holes 231 around the inner cylinder 23, the hot air can fully contact the aerosol generating matrix 100, thereby realizing the full heating of the aerosol generating matrix 100.

[0053] During the process that the aerosol generated by the aerosol generating matrix 100 flows out from the air outlet channel 13 and the intake air flow enters from the air inlet channel 12, due to the assembly gap between the carrier 20 and the notch 11, in order to prevent the aerosol or air flow from leaking, the heat-not-burn device provided in this embodiment further includes a sealing assembly 40, as Figure 3 and Figure 4 shown, the sealing assembly 40 is hermetically arranged between one side of the carrier 20 facing the first outlet 122 of the air inlet channel 12 and / or one side of the carrier 20 facing the second inlet 131 of the air outlet channel 13 and the notch 11.

[0054] In one embodiment, as Figure 1 shown, the notch 11 has at least three wall surfaces, namely a top wall surface 111, a bottom wall surface 112 and a side wall surface 113. In this embodiment, the first outlet 122 of the air inlet channel 12 is located on the bottom wall surface 112 of the notch 11, and the first inlet 131 of the air outlet channel 13 is located on the top wall surface 111 of the notch 11. Then, the sealing assembly 40 is arranged between one side of the carrier 20 facing the top wall surface 111 and the top wall surface 111, and / or the sealing assembly 40 is arranged between one side of the carrier 20 facing the bottom wall surface 112 and the bottom wall surface 112, and then it is sealed by the sealing assembly 40.

[0055] Of course, it is not difficult to understand that in order to avoid the first outlet 122 and the first inlet 131, the sealing assembly 40 is preferably a sealing ring structure, and this sealing ring structure is preferably made of high-temperature resistant materials such as high-temperature silica gel. The gap is sealed by deformation. At the same time, through the deformation of the sealing ring structure, an interference fit connection relationship can also be formed between the carrier 20 and the notch 11 to prevent the carrier 20 from falling off from the notch 11 and improve the installation stability of the carrier 20.

[0056] In one embodiment, for the carrier 20 structure formed by the inner cylinder 23, the outer cylinder 24, and the interlayer space 25 described above, since the air inlet 241 is provided on the outer cylinder 24, the sealing component 40 should also avoid this air inlet 241. Refer to Figure 5 As shown, an avoidance opening 41 is provided on the sealing component 40. This avoidance opening 41 is directly opposite to the air inlet 241, so that the heating air flow can enter the air inlet 241 through the avoidance opening 41.

[0057] In this embodiment, the first inlet 121 of the air inlet passage 12 is opened on the side or end face of the main body 10. For example, the first inlet 121 of the air inlet passage 12 can be opened on the top surface, bottom surface, and side surface of the main body 10. In actual use, the user holds the side of the main body 10 to use it. To prevent the user's hand from blocking the first inlet 121, the first inlet 121 is preferably provided on the top surface, bottom surface, and other parts of the main body 10.

[0058] Refer to Figure 6 As shown, the air inlet passage 12 has at least one air flow path 123. The extending direction of this air flow path 123 is consistent with the notch 11 along the height direction of the main body 10 (such as Figure 6 the double arrow in the vertical direction shown), that is, the setting of this air flow path 123 is along with the notch 11 along the height direction of the main body 10.

[0059] When the heating component 30 heats the aerosol generating matrix 100 in the accommodation cavity 21, part of the heat will be conducted to the main body 10. The setting of the air flow path 123 can preheat the external air entering through the first inlet 121, thus reducing the power consumption of the heating component 30. At the same time, after the external air exchanges heat with the heat conducted to the main body 10 through the air flow path 123, it can also cool down the main body 10 to prevent the user from being uncomfortable due to excessive temperature when holding it.

[0060] In this embodiment, the air flow path 123 is linear. Of course, in other embodiments, the air flow path 123 can also be spiral, curved, etc., to increase the contact area with the main body 10 and improve the heat exchange effect with the main body 10.

[0061] During the output process of the aerosol through the air outlet passage 13, it is necessary to ensure that the air outlet passage 13 and the accommodation cavity 21 are on the same straight line. If the air outlet passage 13 is curved, etc., the aerosol will condense when contacting the passage wall of the air outlet passage 13 during the transmission process, and the condensate will flow back into the accommodation cavity 21, causing the problem of aerosol having a burnt smell.

[0062] For the convenience of users, in this embodiment, a plurality of accommodation cavities 21 may be provided on the carrier 20. The carrier 20 has a plurality of installation states within the notch 11. In different installation states, one end of the intake passage 12 facing the notch 11 and the outlet passage 13 can be respectively docked and communicated with both ends of one of the accommodation cavities 21, so that the aerosol generating matrix 100 in different accommodation cavities 21 can be used in different installation states.

[0063] Of course, aerosol generating matrices 100 with different matrices may also be provided in the plurality of accommodation cavities 21, and the user can select the corresponding aerosol generating matrix 100 according to actual needs.

[0064] As Figure 2 shown, this embodiment also provides a heat-not-burn system, which includes an aerosol generating matrix 100 and the heat-not-burn device in the above embodiment. The aerosol generating matrix 100 does not include a filter section, and it can be a matrix section or a matrix section including a cooling section.

[0065] In summary, for the heat-not-burn device and the heat-not-burn system provided in this application, after the aerosol generating matrix is used up, the carrier can be disassembled from the notch of the main body, and the consumed aerosol generating matrix can be removed. After removal, residues still remain in the accommodation cavity, and tools can be used to clean the residues. Compared with the conventional connection method in which the carrier is integrally integrated into the main body, it is convenient to clean the residues in the accommodation cavity and facilitates user operation.

[0066] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
