[0049] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0050] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0051] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0052] Aerosol matrix can be heated and atomized to produce aerosols. In related technologies, the aerosol matrix consists of at least a matrix segment and a filter segment connected together. The matrix segment is a structure that can be heated to produce aerosols, and the filter segment can filter the aerosols. The temperature of the aerosols produced by the heated matrix segment is usually high, and the filter segment can also provide a certain degree of cooling as the aerosols pass through it. However, due to the limitation of the overall length of the aerosol matrix, the path of aerosol movement is relatively short, resulting in poor cooling effect and failing to meet the needs of normal user operation.

[0053] To address the aforementioned issues, this application provides a heat-not-burning device that directly heats and atomizes the matrix section, and cools the aerosol through a nozzle and a first air channel provided on the nozzle to improve the cooling effect, thereby enabling the generated aerosol to meet the user's needs.

[0054] In the following embodiments, the matrix segment can be an aerosol product in a solid form, such as a column, formed from a smoking material, or it can be a bulk smoking material. The smoking material can be tobacco or other plant materials that can generate aerosols when heated.

[0055] Referring to Figures 1-11, the heated non-combustible device provided in this application includes a nozzle assembly 10, a heating assembly 20, and a one-way valve 30.

[0056] The suction nozzle assembly 10 includes a suction nozzle 11, and a suction nozzle channel 111 and a first air passage 112 are formed inside the suction nozzle 11. The suction nozzle channel 111 extends through both ends of the suction nozzle 11 along its length. The first air passage 112 has an air inlet 113 that connects to the outside. Outside gas, which is air, can enter the first air passage 112 through the air inlet 113.

[0057] The nozzle 11 has a nozzle channel 111 that runs through its length, making it approximately cylindrical in shape. The first air passage 112 is usually located between the inner and outer walls of the cylindrical nozzle 11, and the corresponding air inlet 113 is formed on the outer wall of the cylindrical nozzle 11.

[0058] The heating assembly 20 has a receiving cavity 211 for containing an aerosol matrix. More specifically, the receiving cavity 211 contains a matrix segment of the aerosol matrix. The nozzle 11 can be mated with the heating assembly 20 so that the nozzle channel 111 communicates with the receiving cavity 211. The heating assembly 20 is used to heat the aerosol matrix contained in the receiving cavity 211 to generate an aerosol, and the nozzle channel 111 is used to output the aerosol.

[0059] Understandably, the receiving cavity 211 adopts a groove-shaped structure, so that when the nozzle 11 is connected and engaged with the heating component 20, one end of the nozzle channel 111 is in communication with the opening of the receiving cavity 211. The aerosol matrix segment is contained in the receiving cavity 211, and the matrix segment does not extend beyond the opening of the receiving cavity 211.

[0060] The one-way valve 30 includes a first valve body 31 and a second valve body 32. The first valve body 31 is connected to the nozzle 11, and the second valve body 32 is connected to the heating assembly 20. When the nozzle 11 and the heating assembly 20 are engaged, the first valve body 31 and the second valve body 32 form a one-way airway 300 that allows external gas to flow from the first airway 112 into the receiving cavity 211 in one direction (as shown in Figures 3 and 7). In other words, the two ends of the one-way airway 300 are interconnected with the receiving cavity 211 and the first airway 112.

[0061] It should be noted that when using this heated non-combustible device, the user draws air through the nozzle 11. The nozzle channel 111 creates a negative pressure in the receiving cavity 211. Due to the one-way air passage 300, the negative pressure in the receiving cavity 211 creates a negative pressure in the first air passage 112. External gas can then enter the first air passage 112 through the air inlet 113 and enter the receiving cavity 211 through the one-way air passage 300. The heating component 20 heats and atomizes the matrix section of the aerosol matrix to generate a high-temperature aerosol. This aerosol mixes with the external gas entering the receiving cavity 211 through the one-way air passage 300 and undergoes heat exchange, thereby cooling the generated high-temperature aerosol. The cooled aerosol can then be drawn out through the nozzle channel 111.

[0062] After the aerosol mixes and exchanges heat with the external gas, it achieves a primary cooling effect. Since the first air passage 112 is formed between the inner and outer walls of the columnar nozzle 11, as the aerosol is drawn out through the nozzle passage 111, it can also exchange heat with the external gas flowing through the first air passage 112 via the side wall of the nozzle 11, achieving a secondary cooling effect. Thus, the aerosol can be cooled to a temperature that meets the user's requirements.

[0063] Referring to Figures 1-4 and 8-11, the nozzle assembly 10 also includes a filter element 13. As shown in Figure 15, the nozzle 11 also has a first mounting groove 114 formed inside it. The first mounting groove 114 and the nozzle channel 111 are formed in a stepped hole shape. The first mounting groove 114 is formed at the end away from where the nozzle 11 connects with the heating assembly 20, and the opening of the first mounting groove 114 is located at the end of that end. The filter element 13 is installed in the first mounting groove 114, and can filter the aerosol as it is drawn out from the nozzle channel 111.

[0064] Filter element 13 is usually made of filter cotton or similar materials, which can filter out impurities such as moisture in aerosols to ensure the taste of aerosols.

[0065] Referring to Figures 1-4 and 8-11, the nozzle assembly 10 also includes a cooling air passage 12, which is disposed inside the nozzle channel 111. Specifically, as shown in Figure 16, a second mounting groove 115 is provided at the other end of the nozzle 11 away from the first mounting groove 114. The cooling air passage 12 is disposed in the second mounting groove 115. The second mounting groove 115 and the nozzle channel 111 are both formed into a stepped hole shape. During the process of aerosol being sucked out, it can be cooled by the cooling air passage 12 to further improve the cooling effect.

[0066] The cooling air duct 12 includes an aerosol collection chamber 121, an accelerating air duct 122, and an aerosol buffer chamber 123 connected in sequence. The aerosol collection chamber 121 and the receiving cavity 211 are interconnected when the nozzle 11 is connected to the heating component 20. The first air duct 111 is connected to the aerosol collection chamber 121. External gas enters the aerosol collection chamber 121 through the first air duct 112. The generated aerosol first enters the aerosol collection chamber 121 and mixes thoroughly with the external gas for heat exchange, achieving a rapid cooling effect. The accelerating air duct 122 can accelerate the flow of the cooled aerosol through the external gas to the aerosol buffer chamber 123, reducing suction resistance and improving the user experience. Afterward, it is filtered by the filter element 13 through the aerosol buffer chamber 123 and the nozzle channel 111.

[0067] The speed-increasing airway 122 typically adopts a variable-diameter tubular airway structure. The end of the speed-increasing airway 122 with a larger diameter is connected to the aerosol collection chamber 121, and the end of the speed-increasing airway 122 with a smaller diameter is connected to the aerosol buffer chamber 123, so as to achieve the purpose of speed increase.

[0068] As shown in Figures 1-4 and 8-11, a popping bead 131 can also be provided inside the filter element 13. Flavorings or other popping liquids can be added to these bead 131. Before use, the user can release the popping liquid by squeezing the filter element 13, thus enriching the aerosol's flavor. For example, if the flavoring is mint, the aerosol will have a minty taste.

[0069] Of course, other flavored popping bead liquids can also be added to the popping bead 131 to allow users to choose and meet their diverse needs.

[0070] Referring to Figures 5-7 and 12-14, the first valve body 31 is provided with a first one-way air passage groove 311, which extends through one side of the first valve body 31 in the length direction and one side in the height direction. The opening of the first one-way air passage groove 311 is located on one side of the first valve body 31 in the height direction. The second valve body 32 is provided with a second one-way air passage groove 321, which extends through one side of the second valve body 32 in the length direction and one side in the height direction. Similarly, the opening of the second one-way air passage groove 321 is located on one side of the second valve body 32 in the height direction. After the nozzle 11 is connected to the heating assembly 20, the first valve body 31 and the second valve body 32 are combined, and the first one-way air passage groove 311 through the height direction of the first valve body 31 and the second one-way air passage groove 321 through the height direction of the second valve body 32 are joined to form a one-way air passage 300. The first one-way air passage groove 311 through the length direction of the first valve body 31 and the second one-way air passage groove 321 through the length direction of the second valve body 32 are connected to the receiving cavity 211, so that one end of the one-way air passage 300 is connected to the receiving cavity 211.

[0071] To ensure that the other end of the one-way airway 300 can be connected to the first airway 112, as shown in Figures 5-7, 12, and 13, the first valve body 31 is also provided with a through hole 314 that penetrates the other side of its height direction. The through hole 314 is located at the other end of the first one-way airway groove 311 away from the side that penetrates the length direction of the first valve body 31. The through hole 314 is connected to the first one-way airway groove 311 and the first airway 112, thereby connecting the other end of the one-way airway 300 to the first airway 112.

[0072] It should be noted that the one-way valve 30 structure formed by the first valve body 31 and the second valve body 32 facilitates the cleaning of the first one-way air passage groove 311 and the second one-way air passage groove 321 on the first valve body 31 and the second valve body 32. For example, if the nozzle 11 and the heating assembly 20 are detachably connected, the first one-way air passage groove 311 and the second one-way air passage groove 321 can be cleaned when the nozzle 11 is separated from the heating assembly 20. For details on the specific connection method between the nozzle 11 and the heating assembly 20, please refer to subsequent embodiments.

[0073] As shown in Figures 5, 6 and 12, the first one-way air passage groove 311 and the second one-way air passage groove 321 have the structural form of a Tesla valve. Thus, the one-way air passage 300 formed by the combination of the first one-way air passage groove 311 and the second one-way air passage groove 321 is a Tesla valve, which can realize one-way fluid flow.

[0074] It should be noted that the first one-way air passage groove 311 penetrates one side of the first valve body 31 and the second one-way air passage groove 321 penetrates one side of the second valve body 32 to form the outlet end of the one-way air passage 300. The outlet end is connected to the receiving cavity 211, while the through hole 314 forms the inlet end of the one-way air passage 300. The inlet section is connected to the first air passage 112, which ensures that the external gas entering the first air passage 112 through the air inlet hole 113 can enter the receiving cavity 211 through the one-way air passage 300.

[0075] Understandably, one side of the second valve body 32 along its length should be kept basically flush with the receiving cavity 211 to ensure that the matrix segment can be smoothly placed into the receiving cavity 211.

[0076] Of course, the second valve body 32 and the heating assembly 20 can also be connected by a quick-release method. In this way, the extension position of the second valve body 32 is not limited. For example, one side of the second valve body 32 in the length direction can extend into the receiving cavity 211. The second valve body 32 can be quickly removed from the heating assembly 20 during the process of putting the substrate segment into the receiving cavity 211, and the second valve body 32 can be installed back in its original position after the substrate segment is put into the receiving cavity 211.

[0077] Referring to Figures 5, 6, and 12, a plurality of first one-way air passage grooves 311 are provided on one side of the first valve body 31, and a plurality of second one-way air passage grooves 321 are provided on one side of the second valve body 32. The plurality of first one-way air passage grooves 311 and the plurality of second one-way air passage grooves 321 correspond one-to-one, so that when the first valve body 31 and the second valve body 32 are combined, a plurality of one-way air passages 300 are formed to ensure that more external gas enters the receiving cavity 211, so that the high-temperature aerosol can be more fully mixed and cooled.

[0078] As shown in Figure 16, the first air passage 112 between the inner and outer walls of the suction nozzle 11 is arranged in the axial direction surrounding the suction nozzle 11, so that external gas can flow through the side walls of the suction nozzle 11. This increases the contact area between the aerosol and the air passage 112, thereby enhancing the heat exchange efficiency.

[0079] To ensure that external gas can smoothly enter the one-way airway 300 through the first airway 112, as shown in Figure 16, a first notch 116 is provided at the end of the nozzle 11 away from the first mounting groove 114. This first notch 116 communicates with the first airway 112, and the first valve body 31 is installed in the first notch 116. As shown in Figure 17, the heating assembly 20 is provided with a second notch 213, which communicates with the receiving cavity 211. The second valve body 32 is installed in the second notch 213. As shown in Figures 5, 6, and 12, the first one-way airway groove 311 penetrates the wall of the through hole 314 provided on the first valve body 31. Thus, after the nozzle 11 is connected to the heating assembly 20, the first airway 111 is indirectly connected to the receiving cavity 211 through the through hole 314 and the one-way airway 300 surrounded by the first one-way airway groove 311 and the second one-way airway groove 321.

[0080] Referring to Figures 5-7, the first valve body 31 has a first plane 315 along its height direction on one side, and the second valve body 32 has a second plane 322 along its height direction on one side. The first plane 315 and the second plane 322 fit together after the nozzle 11 and the heating assembly 20 are connected, which can play a certain sealing role to prevent excessive gaps from appearing between the first plane 315 and the second plane 322 after the first valve body 31 and the second valve body 32 are combined.

[0081] Among them, one side of the first plane 315 is the side where the first one-way air passage groove 311 passes through the first valve body 31, and one side of the second plane 322 is the side where the second one-way air passage groove 321 passes through the second valve body 32, with only the through hole 314 on the first valve body 31 remaining in communication with the first air passage 112.

[0082] One of the first valve body 31 and the second valve body 32 has a recessed portion. One of the first one-way air passage grooves 311 and 321 is located at the bottom of the recessed portion. After the suction nozzle 11 is connected to the heating assembly 20, at least one of the first valve body 31 and the second valve body 32 is at least partially embedded in the recessed portion. This arrangement allows the first valve body 31 and the second valve body 32 to be quickly and accurately connected during the connection process between the suction nozzle 11 and the heating assembly 20.

[0083] As shown in Figure 12, the recess is provided on the first valve body 31, and the first one-way air passage groove 311 is provided at the bottom of the recess. The second valve body 32 can be fully or partially embedded in the recess. For distinction, the recess in which the second valve body 32 is fully embedded is defined as the first recess 312, and the recess in which the second valve body 32 is partially embedded is defined as the second recess 313.

[0084] Referring to Figures 12 and 13, the first valve body 31 has a first recess 312, and a first one-way air passage groove 311 is disposed at the bottom of the first recess 312. The size of the first recess 312 is greater than or equal to the size of the second valve body 32. Thus, after the nozzle 11 is connected to the heating assembly 20, the second valve body 32 is embedded in the first recess 312.

[0085] Referring to Figures 12 and 14, the first valve body 31 has a second recess 313, and a first one-way air passage groove 311 is disposed at the bottom of the second recess 313. The size of the second recess 313 is smaller than the size of the second valve body 32. Thus, after the nozzle 11 is connected to the heating assembly 20, part of the second valve body 32 is embedded in the second recess 313.

[0086] A first recess 312 or a second recess 313 is provided on the first valve body 31, so that during the connection between the suction nozzle 11 and the heating assembly 20, all the second valve bodies 32 can be embedded in the first recess 312, or a portion of the second valve bodies 32 can be embedded in the second recess 313, which facilitates the quick and accurate docking of the first valve body 31 and the second valve body 32.

[0087] After the nozzle 11 is connected to the heating component 20, in order to further improve the sealing effect between the two, as shown in Figures 3 and 10, the heating non-combustible device provided in this application also includes a sealing component 40. The sealing component 40 is disposed between the heating component 20 and the nozzle 11 to seal the gap between the heating component 20 and the nozzle 11.

[0088] The sealing assembly 40 includes an annular sealing gasket 41, which is disposed between the heating assembly 20 and the suction nozzle 11, as shown in FIG18. The annular sealing gasket 41 has a hollow portion 411, which is used to avoid the first valve body 31 or the second valve body 32.

[0089] Referring again to Figures 1-4 and 8-11, the sealing assembly 40 also includes a sealing ring 42. The heat-not-burning device provided in this application also includes a cover 50 and a housing 60. The nozzle 11 is disposed through the cover 50, and the heating assembly 20 is disposed on the housing 60. The cover 50 is movably disposed on the housing 60 to open or close the opening of the receiving cavity 211. This allows for easy removal of the heated aerosol matrix from the receiving cavity 211 when the opening of the receiving cavity 211 is opened, or for the installation of unused aerosol matrix into the receiving cavity 211. The sealing ring 42 is disposed on the cover 50 or the housing 60 and surrounds the periphery of the nozzle 11 or the periphery of the opening of the receiving cavity 211 to seal the gap between the cover 50 and the housing 60.

[0090] Figures 4 and 11 show the cover 50 rotating relative to the housing 60 to open the cavity 211. Alternatively, the cover 50 can be slidably connected to the housing 60, which also opens the cavity 211.

[0091] Referring to Figures 3 and 10, an annular receiving groove 51 is provided on the cover 50 around the nozzle 11, and an annular mounting groove 61 is provided on the housing 60 around the opening of the receiving cavity 211. The sealing ring 42 is installed in the annular mounting groove 61. After the cover 50 and the housing 60 are connected, part of the sealing ring 42 is accommodated in the annular receiving groove 51, so that the sealing ring 42 is positioned by means of the annular receiving groove 51 and the annular mounting groove 61 to seal the gap between the cover 50 and the housing 60.

[0092] Referring again to Figures 1-4 and 8-11, the heating assembly 20 includes a heating cup 21, a receiving cavity 211 disposed within the heating cup 21, and the heating cup 21 connected to the nozzle 11. The heating cup 21 is provided with a second air passage 212, which is typically disposed between the inner and outer walls of the heating cup 21. One end of the second air passage 212 communicates with the receiving cavity 211, and the other end of the second air passage 212 communicates with the first air passage 112 when the heating cup 21 is connected to the nozzle 11.

[0093] As external gas enters the first air passage 112 through the air inlet 113 and then enters the receiving cavity 211 through the one-way air passage 300, a small portion of the external gas enters through the one-way air passage 300, while most of the external gas enters the receiving cavity 211 through one end of the second air passage 212. This portion of the external gas is more likely to form an aerosol.

[0094] Referring to Figures 3 and 10, the heating assembly 20 also includes a heating element 22, which is disposed inside the heating cup 21 and defines a receiving cavity 211 above the inner cavity of the heating cup 21. The heating element 22 has multiple heat exchange channels 221, one end of which is connected to one end of a second channel 212, and the other end of which is connected to the receiving cavity 211. In other words, the external gas is heated after passing through the heat exchange channels 221 and enters from the bottom of the receiving cavity 211 to heat the aerosol matrix with the heated external gas.

[0095] To facilitate the connection between the first air passage 112 and the second air passage 212 after the heating cup 21 and the nozzle 11 are connected, as shown in Figure 16, a plurality of first connecting holes 117 are provided on the end face of the nozzle 11 at the other end away from the first mounting groove 114. The first connecting holes 117 are connected to the first air passage 112. As shown in Figure 17, a plurality of second connecting holes 214 are provided on the end face of the heating cup 21 at the cup mouth. The second connecting holes 214 are connected to the second air passage 212. Furthermore, the plurality of first connecting holes 117 and the plurality of second connecting holes 214 correspond one-to-one. After the nozzle 11 and the heating cup 21 are connected, the first connecting holes 117 and the second connecting holes 214 can be connected to each other, thereby indirectly connecting the first air passage 112 and the second air passage 212.

[0096] It should be noted that after the suction nozzle 11 is connected to the heating cup 21, the sealing gasket 41 in the sealing assembly 40 is set between the suction nozzle 11 and the heating cup 21. Thus, as shown in Figure 18, a third connecting hole 412 is also provided on the sealing gasket 41, which can ensure that the first connecting hole 117 and the second connecting hole 214 are in a connected state.

[0097] In summary, the heated non-combustible device provided in this application allows external gas to enter the first air passage 112 through the air inlet 113 and then enter the receiving cavity 211 through the one-way air passage 300. This allows the aerosol to mix with the external gas entering through the one-way air passage 300 and exchange heat, achieving a primary cooling effect. Furthermore, during the aerosol output through the suction nozzle channel 111, it can also exchange heat with the external gas flowing through the first air passage 112 through the side wall of the suction nozzle 11, achieving a secondary cooling effect. Thus, the aerosol can be cooled to a temperature that meets the user's usage requirements.
