[0036] ​​The application will be described in further detail below with specific reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the application can be practiced without some or all of these specific details.

However, it will be apparent to one skilled in the art that the application can be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order not to unnecessarily obscure the application.

[0037] 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 be sequentially adjusted or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0038] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0039] The heating non-combustion device provided by the application is applied to a shell with a removable cover, a heater with a through heat exchange hole is arranged in the air guide channel of the cup body, and a containing space for containing an aerosol product is defined by the heater and the cup body, so that when the air flow enters the cup body, the air flow is heated to form a hot air flow when passing through the heat exchange hole of the heater, and the aerosol product in the containing space is heated, thereby balancing the temperature difference of the air flow in different regions and making the heating more uniform, which is beneficial to improve the heating effect of the aerosol product.

[0040] The aerosol product described in the application can be a columnar smoking substrate without a filter and a cooling section, such as tobacco or non-tobacco plants, which can be directly carried on the heater for heating to generate an aerosol. The aerosol product is a gas-permeable structure with a loose microporous structure inside, and an axial hole can also be provided in the aerosol product to facilitate the outflow of the aerosol.

[0041] Some embodiments of the heating non-combustion device and the heating non-combustion system provided by the application will be described below with reference to the drawings.

[0042] In the embodiments of the first aspect of the application, a heating non-combustion device 100 is provided, as shown in Figure 1, Figure 2 and Figure 3 As shown, the heated non-combustible device 100 includes a cup body 11, a tube body 12, and a heater 13. The cup body 11 and the tube body 12 are correspondingly arranged in a first direction. The cup body 11 has a first open end 111 and a first closed end 112 that are oppositely arranged in the first direction. The cup body 11 has a gas guiding channel inside, and a plurality of gas guiding holes 116 extending in the first direction are opened in the side wall of the cup body 11. One end of the gas guiding hole 116 communicates with the first open end 111, and the other end communicates with the gas guiding channel. Correspondingly, the tube body 12 is through in the first direction and has a second open end 121 and a suction port 122 that are oppositely arranged in the first direction. The second open end 121 faces the cup body 11 and is correspondingly arranged with the first open end 111 so that the tube body 12 can communicate with the cup body 11 when it is connected. The suction port 122 is located on the tube body at the end away from the cup body 11. When the second opening end 121 is connected to the first opening end 111, the suction port 122 of the tube body 12 can be connected to the air guide channel 110 of the cup body 11, and the air guide hole 116 of the cup body 11 can be connected to the outside atmosphere through the tube body 12.

[0043] Among them, such as Figure 3 and Figure 4 In the example, heater 13 is disposed within the gas guiding channel 110 of cup body 11. The end of heater 13 facing the first opening end 111 defines a receiving space 1141 with cup body 11 for receiving aerosol products. The end of gas guiding hole 116 communicating with gas guiding channel 110 is located at the end of heater 13 away from receiving space 1141. Heater 13 has multiple heat exchange holes 1311, and each heat exchange hole 1311 is through a first direction. After airflow enters gas guiding channel 110 through gas guiding hole 116, it flows through heat exchange hole 1311 on heater to receiving space 1141. The airflow is heated as it passes through heat exchange hole 1311 to form hot airflow. After the hot airflow enters receiving space 1141, it heats aerosol products to generate corresponding aerosols. The aerosols can flow out from suction port 122 of tube body 12 with the airflow. Tube body 12 can cool the passing airflow.

[0044] It is understandable that in some heated non-combustible devices, if heaters are installed on the outer or bottom wall of the heating cup to heat the airflow, the heat conduction effect of the cup is difficult to improve effectively. Moreover, the airflow from different air vents impacts each other after entering the cup, which can easily lead to airflow turbulence. After the airflow is heated, there is a large temperature difference, resulting in uneven heating of the aerosol products.

[0045] The heating non-combustible device 100 in this embodiment improves and optimizes the structure by providing a heater 13 with multiple heat exchange holes 1311 inside the cup body 11. This allows the gas passing through the heat exchange holes 1311 to be heated to form a hot airflow, which then penetrates and heats the aerosol product inside the tube body 12. This effectively alleviates airflow turbulence, balances the temperature difference between different areas, and alleviates the problem of uneven heating, thus improving the heating effect of the aerosol product.

[0046] In practical applications, since the heater 13 can heat the airflow passing through the heat exchange hole 1311 to form a hot airflow in this embodiment, the heater 13 can contact the bottom of the aerosol product or a certain gap can be set between the heater 13 and the bottom of the aerosol product, both of which can achieve the heating effect of the aerosol product.

[0047] For example, the heater 13 may be in contact with the inner wall of the cup body 11, and the aerosol product may be in contact with or have a very small gap between its periphery and the inner wall of the cup body 11, so that the hot airflow can pass through the aerosol product as much as possible for heating.

[0048] It should be noted that the heat-not-burning device 100 in this embodiment adopts a split cup body 11 and tube body 12, which can be applied to a split-structure housing, such as a device structure with a lid-type housing. The cup body 11 is placed in the housing of the atomizing device, while the tube body 12 is installed in the lid of the atomizing device, so as to open or close as needed to facilitate the replacement of aerosol products. The cup body 11, tube body 12, and heater 13 are not limited to the following: Figures 1 to 4 The cylindrical structure shown can also be replaced with a prism structure or other structural forms depending on the specific application requirements.

[0049] In further embodiments of this application, such as Figure 3 , Figure 4 and Figure 5 As shown, the heater 13 includes a heat-conducting substrate 131 and a heating element 132. The heat-conducting substrate 131 has multiple heat exchange holes 1311 extending along a first direction, and each heat exchange hole 1311 extends along the first direction. The heating element 132 has a mesh structure and is circumferentially wrapped around the outer wall of the heat-conducting substrate 131. The heating element 132 can be electrically connected to a power supply component to generate heat when energized and to supply heat to the heat-conducting substrate 131. By setting the heating element 132 with a mesh structure, on the one hand, the coverage area of ​​the heating element 132 can be expanded, saving materials; on the other hand, heat conduction can be promoted, reducing energy consumption. Airflow can pass through the heat-conducting substrate 131 through different heat exchange holes 1311 and be heated to form a hot airflow to heat the aerosol product in the containing space 1141.

[0050] Furthermore, such as Figure 4 andFigure 5 In the example shown, the heating element 132 includes a positive electrode line 1321, a negative electrode line 1322, and a heating pattern 1323. The positive electrode line 1321 and the negative electrode line 1322 are spaced apart in a first direction. The heating pattern 1323 is located between the positive electrode line 1321 and the negative electrode line 1322, with one end of the heating pattern 1323 connected to the positive electrode line 1321 and the other end connected to the negative electrode line 1322 in the first direction, forming a mesh structure for the heating element 132. In application, the positive electrode line 1321 and the negative electrode line 1322 can be electrically connected to a power supply component to form a current-carrying circuit in the heating element 132, causing the heating pattern 1323 to generate heat. The positive electrode line 1321 and the negative electrode line 1322 can be configured as follows: Figure 5 The circuit structure shown in the figure, the spacing between the two and the shape of the heating pattern 1323 can be set according to different heat generation requirements.

[0051] Furthermore, in a specific implementation, such as Figure 5 , Figure 6 and Figure 7 In the example, the heating pattern 1323 includes multiple sets of first heating structures 1324 arranged sequentially in the circumferential direction. Each set of first heating structures 1324 is connected to a positive electrode line 1321 and a negative electrode line 1322, respectively. Each set of first heating structures 1324 includes multiple first heating units 1325 connected sequentially along a first direction. Specifically, a first heating unit 1325 adjacent to the positive electrode line 1321 in the first direction is connected to the positive electrode line 1321, and a first heating unit 1325 adjacent to the negative electrode line 1322 is connected to the negative electrode line 1322, forming a mesh-like heating structure. It should be noted that the number of sets of first heating structures 1324 and the number of first heating units 1325 in each set can be set according to the specific dimensions of the heating substrate; the first heating units 1325 are not limited to... Figures 5 to 7 The shape shown can also be other structural forms.

[0052] Furthermore, such as Figure 6 In the example, among the multiple sets of first heating structures 1324, at least one set is spaced apart in the circumferential direction, that is, there is a certain gap between at least one set of first heating structures 1324 and other first heating structures 1324 adjacent in the circumferential direction, and the two do not directly contact each other, so that the first heating structure 1324 forms a parallel relationship with other first heating structures 1324.

[0053] Furthermore, such as Figure 7In the example, the heating pattern 1323 also includes a connecting line 1330, which is located between at least two adjacent sets of first heating structures 1324, and the two ends of the connecting line 1330 are respectively connected to the positive electrode line 1321 and the negative electrode line 1322, for example. Figure 7 The connecting line 1330 extending along the first direction is shown in the figure; the adjacent first heating structure 1324 can be connected to the connecting line 1330 so that the adjacent first heating structures 1324 are connected in the circumferential direction as a whole.

[0054] In further embodiments of this application, such as Figures 5 to 7 In the example, each first heating unit 1325 of the heating pattern 1323 has a hollow structure, which can further reduce power consumption and increase heating temperature. Specifically, the first heating unit 1325 can adopt a closed pattern, for example... Figure 5 The structure shown is either elliptical or circular. Of course, the first heating unit 1325 can also adopt a non-enclosed structure, such as... Figure 6 and Figure 7 The X-shaped structure shown in the image.

[0055] Furthermore, such as Figures 4 to 7 In the example, the heating element 132 can be in the form of a flexible printed circuit, which is connected to the outer wall of the heat-conducting substrate 131 by printing and forms an integral structure.

[0056] In further embodiments of this application, such as Figures 5 to 8 In the example shown, multiple heat exchange holes 1311 on the heat-conducting substrate 131 are arranged in an array relative to the central axis of the heat-conducting substrate 131, so that the arrangement of the multiple heat exchange holes 1311 is more uniform, and the hot airflow generated by the gas passing through the multiple heat exchange holes 1311 is more uniformly distributed. The heat exchange holes 1311 can be made as follows: Figure 8 The arrangement of the heat exchange holes 1311 in a ring array, as shown, forms multiple concentric circles, thereby increasing the number of heat exchange holes 1311 within a limited space and improving heating efficiency. It should be noted that the arrangement of the heat exchange holes 1311 is not limited to... Figure 8 The ring array shown can also be configured as a matrix, specifically using an arrangement adapted to the shape of the heat-conducting substrate 131. For example, when the heat-conducting substrate 131 adopts a shape such as... Figure 7 and Figure 8 When the cylindrical structure is shown, the heat exchange holes 1311 are arranged in a ring array. When the heat-conducting substrate 131 is in the shape of a cube or cuboid, the heat exchange holes 1311 are arranged in a matrix, which is beneficial to further improve the space utilization, increase the number of heat exchange holes 1311, and make the distribution of heat exchange holes 1311 more uniform.

[0057] In further embodiments of this application, such as Figures 5 to 8 As shown, the porosity of the heat-conducting substrate 131 is set to 20% to 85%, meaning that the total volume of all heat exchange holes 1311 accounts for 20% to 85% of the volume within the three-dimensional space formed by the heat-conducting substrate 131. Furthermore, the porosity can be set within the range of 25% to 80%, for example, 60%, 65%, 70%, and 75%, effectively balancing the structural requirements of the heat-conducting substrate 131 with the heating requirements. In practical applications, different numbers of heat exchange holes 1311 can be set according to the specific dimensions of the heat-conducting substrate 131 to meet the aforementioned porosity requirements.

[0058] In further embodiments of this application, such as Figures 5 to 8 As shown, in the heat-conducting substrate 131, the ratio of the total volume of all heat exchange holes 1311 to the volume of the heat-conducting substrate 131 is in the range of 1:5.5 to 1:1.5 (including the values ​​at both ends). Here, the volume of the heat-conducting substrate 131 specifically refers to the solid volume (i.e., the volume of the solid excluding the heat exchange holes 1311). Further, the above volume ratio is in the range of 1:5 to 1:2, for example, 1:4.5, 1:4, 1:3.5, 1:3, 1:2.5. This can meet the structural requirements of the heat-conducting substrate 131 while simultaneously meeting the heating requirements. Specifically, different numbers of heat exchange holes 1311 can be set according to different dimensions of the heat-conducting substrate 131 to meet the above volume ratio requirements.

[0059] Furthermore, in a specific example, such as Figures 5 to 8 The total number of heat exchange holes 1311 can be 2N, where N is a positive integer. The diameter of the heat exchange holes 1311 can be set in the range of 0.1mm to 1mm. The shape of the heat exchange holes 1311 can be a circular hole as shown in the figure, or a square hole or other types of holes, such as regular polygonal holes, as needed. Furthermore, heat exchange holes 1311 of different shapes can be set simultaneously according to usage requirements, meaning that multiple heat exchange holes 1311 include two or more combinations of the aforementioned different hole shapes. For example, in one example, multiple heat exchange holes 1311 can be arranged in a ring array, with the outer ring of heat exchange holes 1311 using circular holes and the inner ring using square holes. This arrangement helps to fully utilize the limited space of the heat-conducting substrate 131, increase the number of heat exchange holes 1311, and make the arrangement of the heat exchange holes 1311 more uniform, thereby further increasing the generated hot air flow rate and enhancing the heating effect.

[0060] In further embodiments of this application, such as Figure 3 , Figure 4 and Figure 8 and Figure 9As shown, the air guiding channel 110 includes an air guiding chamber 113 and a heating chamber 114. In the first direction, the air guiding chamber 113 is located between the heating chamber 114 and the first closed end 112, and communicates with the heating chamber 114. The heating chamber 114 is also communicated with the first open end 111. The heater 13 is disposed in the heating chamber 114, and the receiving space 1141 for accommodating the aerosol product 300 is located in the heating chamber 114 near the first open end 111. The end of the air guiding hole 116 of the cup body 11 away from the first open end 111 communicates with the air guiding chamber 113. A flow guiding structure 14 is provided inside the air guiding cavity 113, and the flow guiding structure 14 is connected and fixed to the inner wall surface of the air guiding cavity 113 near the first closed end 112. The orthogonal projection of the flow guiding structure 14 is located between multiple air guiding holes 116, so as to block the air intake airflow from flowing laterally through the flow guiding structure 14, thereby separating the air intake airflow in different directions and guiding the airflow in different directions to flow towards the heat exchange hole 1311 of the heater 13.

[0061] Furthermore, the flow guiding structure 14 has a first flow guiding surface 141 on its side, for example... Figure 3 and Figure 4 In the example shown, the flow guiding structure 14 is inclined towards the bottom centerline of the heater 13 to guide the airflow to flow through different heat exchange holes 1311 of the heater 13. Laterally, the first flow guiding surface 141 faces one end of the air guide hole 116 that connects to the air guide cavity 113. When the airflow enters the air guide cavity 113 through the air guide hole 116 and flows laterally to the side of the flow guiding structure 14, it can change its flow direction under the guidance of the first flow guiding surface 141 and turn towards the heater 13 in a first direction. This allows the airflow to pass through different heat exchange holes 1311 on the heat-conducting substrate 131 and generate hot airflow after being heated. It is understood that airflow is prone to impact and turbulence when it encounters obstacles during its movement. The first flow guiding surface 141 guides the airflow, allowing it to change direction more smoothly, thus reducing airflow impact and preventing turbulence.

[0062] The first guide surface 141 can be configured in different forms according to actual usage requirements. For example, the first guide surface 141 can adopt the following form: Figure 9 and Figure 10 The diagram shows a smooth curved surface structure, with the first guide surface 141 extending continuously in the circumferential direction and surrounding the centerline of the heater 13 to enhance the guiding effect. This allows airflow from different directions to flow more smoothly towards the heater 13 under the guidance of the first guide surface 141, while also expanding the coverage area of ​​the first guide surface 141. Specifically, the first guide surface 141 can be designed as follows: Figure 9 The longitudinal section profile shown is a straight line structure, which can also be adopted as follows: Figure 10The longitudinal section shown is a concave curve to make the first guide surface 141 smoother and further enhance the stability of guiding the airflow. Of course, the guide structure 14 can also adopt other structural forms according to specific application requirements.

[0063] In further embodiments of this application, such as Figure 9 In the example, in the first direction, there is a first gap H between the flow guiding structure 14 and the heater 13. The interface between the air guiding cavity 113 and the heating cavity 114 in the first direction is a first interface 115. The inner sidewall of the cup body 11 extends to the first interface 115 and has a first gap h1 between it and the bottom wall. The air guiding hole 116 in the sidewall communicates with the air guiding cavity 113 through the first gap h1, so that the airflow in the air guiding hole 116 can smoothly enter the air guiding cavity 113. Correspondingly, in the first direction, the bottom surface of the heater 13 is higher than the bottom surface of the inner sidewall, that is, there is a second gap h2 between the bottom surface of the heater 13 and the first interface 115. It is understandable that when the gas in the air guide cavity 113 flows to the bottom surface of the heater 13 under the guidance of the flow guide structure 14, some of the airflow will inevitably flow laterally to the inner wall of the cup body 11. Due to the existence of the second gap h2, the airflow flowing to the inner wall can be further guided, so that the airflow turns and flows back to the air guide cavity 113, so as to prevent the airflow from flowing back to the air guide hole 116 and causing airflow turbulence.

[0064] In a further embodiment, such as Figure 10 In the example, the lateral edge of the air guide cavity 113 extends to one end of the air guide hole 116 near the first closed end 112 and communicates with the air guide hole 116, so that the orthographic projection of the air guide hole 116 in the first direction is entirely located within the air guide cavity 113; the lateral edge of the air guide cavity 113 also has a second guide surface 1131, so that when the airflow enters the air guide cavity 113 from the air guide hole 116, it can be guided by the second guide surface 1131, thereby flowing more gently along the side to the guide structure 14.

[0065] Furthermore, such as Figure 2 In the example, the air guide hole 116 can specifically adopt a triangular cross-section structure. Multiple air guide holes 116 are arranged at intervals along the circumference of the cup body 11, and the base of the triangle faces the inner wall of the air guide channel 110, while the vertex opposite to the base faces the outer wall of the air guide channel 110. This increases the heating area of ​​the airflow when it passes through the air guide hole 116, achieving a preheating effect and further improving the heating effect of the hot airflow.

[0066] In further embodiments of this application, such as Figure 9In the example shown, the inner wall of the heating chamber 114 of the cup body 11 has a support structure 117. The support structure 117 protrudes inward from the heating chamber 114, and the end of the heater 13 facing the air guide chamber 113 abuts against the support structure 117 to provide support for the heater 13. Specifically, the support structure 117 is located at the end of the heating chamber 114 near the air guide chamber 113. The support structure 117 can specifically adopt a design such as... Figure 9 The support block shown is in the form of a multi-point support for the heater 13, with multiple support blocks spaced apart in the circumferential direction of the heating cavity 114; or, the support structure 117 can also be configured as a continuous structure extending in the circumferential direction, so that a step-like structure is formed in the heating cavity 114, which can increase the contact area with the heater 13 and make the support more stable.

[0067] It should be noted that the above support structure 117 is only a preferred support method for the heater 13. In practical applications, other support methods can also be used. For example, at least part of the cross-sectional area of ​​the heating cavity 114 can be set to gradually decrease in the direction close to the air guide cavity 113 along the first direction. That is, part or all of the heating cavity 114 forms a similar trumpet-shaped constriction structure. The outer wall of the heater 13 can be snapped and fixed with the side wall of the heating cavity 114, and support the heater 13.

[0068] In further embodiments of this application, such as Figure 4 , Figure 9 and Figure 10 In the example, the air guide channel 110 is also provided with an air collecting plate 15, which covers the end of the heater 13 facing the first opening end 11. The air collecting plate 15 has multiple air collecting holes 151, which are correspondingly arranged with the heat exchange holes 1311 of the heater 13, so that the airflow can further pass through the air collecting holes 151 after passing through the heat exchange holes 1311. Specifically, the diameter of the air collecting holes 151 gradually decreases in the direction close to the tube body 12 along the first direction, so that the flow velocity of the hot airflow can be increased when it passes through the air collecting holes 151. Figure 9 In the example, when the aerosol article 300 is contained in the containment space 1141, the gas collecting plate 15 is located between the heater 13 and the aerosol article 300.

[0069] Furthermore, such as Figure 4 and Figure 9 In the example shown, the air collecting hole 151 is specifically in the form of a conical hole, and in the first direction, the ratio of the port areas at both ends of the air collecting hole 151 is in the range of 1:2 to 1:1.5. Of course, the end face shape of the air collecting hole 151 can also adopt other structural forms, such as circular, triangular, square or other polygonal shapes.

[0070] In further embodiments of this application, such as Figure 3and Figure 4 As shown, the tube body 12 has an air intake chamber 123 and a cooling chamber 124, and the air intake chamber 123 and the cooling chamber 124 are isolated from each other. The cooling chamber 124 is formed through the tube body 12 in a first direction and is connected to the suction port 122. The air intake chamber 123 is located in the side wall of the tube body 12 and is connected to the second opening end 121 and the outside atmosphere. The air intake chamber 123 is used for air intake, and the cooling chamber 124 is connected to the air intake chamber 123 at the second opening end 121. With the second opening end 121 of the tube body 12 aligned with the first opening end 111 of the cup body 11, the air inlet chamber 123 is connected to the air guide hole 116 of the cup body 11. Airflow entering the air inlet chamber 123 from the outside can pass through the air guide hole 116 of the cup body 11 and enter the air guide chamber 113. At the same time, the cooling chamber 124 is connected to the air guide channel 110 of the cup body 11, so that the hot airflow generated by heating inside the cup body 11 completes the heating of the aerosol product and then enters the cooling chamber 124 for corresponding cooling, so that the airflow temperature flowing to the suction port 122 drops to a suitable temperature and prevents scalding. Specifically, the air intake chamber 123 can adopt a ring-shaped sandwich structure, that is, the air intake chamber 123 surrounds the outside of the cooling chamber 124, and the cooling chamber 124 and the air intake chamber 123 form a nested arrangement so that the position of the air intake chamber 123 matches the air guide hole 116 of the cup body 11; an air inlet 1231 can be opened on the side wall of the air intake chamber 123 for air intake. For example, Figure 4 In the example shown, at least one cooling structure 125 is provided in the cooling cavity 124 for cooling the hot airflow. The cooling structure 125 can take different structural forms, such as... Figure 4 The constricted structure shown in the diagram has a gradually decreasing ventilation area of ​​the cooling structure 125 along the first direction away from the cup body 11, achieving a cooling effect on the hot airflow. Conversely, the end of the cooling structure 125 facing the suction port 122 is designed as an open form with a gradually increasing ventilation area, reducing the flow velocity after the airflow passes through. When multi-stage cooling is required, multiple cooling structures 125 can be spaced apart along the first direction within the cooling chamber 124 to meet actual cooling needs.

[0071] In further embodiments of this application, such as Figure 11 , Figure 12 and Figure 13As shown, the heated non-combustible device also includes a housing 21. In a first direction, one end of the housing 21 is an assembly end 211, and the assembly end 211 is connected to a movable cover 22. The cover 22 is capable of relative movement to either seal or expose the assembly end 211. A cup body 11 is connected to the assembly end 211, and a tube 12 passes through the cover 22. As shown in the example, the cup body 11 is installed inside the housing 21, and the first open end 111 is located at the assembly end 211. Correspondingly, the second open end 121 of the tube 12 is located at the end of the cover 22 facing the cup body 11, and the suction port 122 extends from the end of the cover 22 away from the housing 21.

[0072] Among them, such as Figure 1 , Figure 2 as well as Figure 11 In the example shown, the pipe body 12 has an air inlet 1231, which connects the air intake chamber 123 to the outside atmosphere, allowing airflow to enter the air intake chamber 123 through the air inlet 123. The air inlet 1231 can be located as follows: Figure 11 The side wall of the tube 12 shown is positioned near the suction port 122 so that the air inlet 1231 is exposed on the outside of the cover 22 to prevent blockage. The assembly end 211 has a first assembly hole 212, in which the cup body 11 is disposed. Correspondingly, the cover 22 has a second assembly hole 221 extending along a first direction, in which the tube 12 passes.

[0073] Before use, the cover 22 can be opened to expose the assembly end 211 and separate the cup body 11 from the tube body 12. At this time, the aerosol product 300 can be inserted into the receiving space 1141 of the cup body 11. During use, as follows... Figure 11 and Figure 13 In the example shown, the lid 22 is closed, and the assembly end 211 is sealed, at which point the cup body 11 is connected to the tube body 12. Airflow sequentially passes through the air inlet chamber 123 of the tube body 12 and the air guide hole 116 of the cup body 11, entering the air guide chamber 113. Guided by the flow guide structure 14, the airflow passes relatively evenly through different heat exchange holes 1311 on the heater 13 and is heated to form a hot airflow. Then, the hot airflow heats the aerosol product 300 assembled in the containing space 1141 to generate aerosol. When not in use, the lid 22 can be opened to replace the aerosol product with a different flavor.

[0074] Furthermore, in practical applications, the heating and non-burning device can also be equipped with a corresponding power supply component inside the housing according to the usage requirements. The power supply component is electrically connected to the heater to supply power to the heater so that the heater heats up when energized, and the gas passing through the heat exchange hole forms a hot gas flow.

[0075] It should be noted that the shapes of the shell 21 and the cover 22 are not limited to those of other types. Figure 11 and Figure 12 The example shown can be customized to other shapes and structures according to specific usage needs. The opening method of the cover 22 is not limited to... Figure 12 The flip-opening shown in the diagram involves rotating the connector 213 to form a rotatable connection between the cover 22 and the housing 21, thereby exposing the mounting end 211 of the housing 21 by flipping the cover 22 open. Of course, the cover 22 can also be opened by sliding or rotating. Additionally, as... Figure 12 and Figure 13 In the example, a locking element 214 adapted to the cover 22 can also be provided so that the cover 22 can be locked by the locking element 214 when the cover 22 is closed, so that the cover 22 can move freely and be accidentally opened.

[0076] An embodiment of the second aspect of this application provides a heating non-combustible combustion system, such as... Figure 9 and Figure 10 As shown, it includes an aerosol product 300 and a heating non-burning device 100 as described in any of the embodiments of the first aspect above. The cup body 11 of the heating non-burning device 100 has a receiving space 1141, and the aerosol product 300 is configured to be received in the receiving space 1141 of the cup body 11 so as to heat the aerosol product 300 by the heater 13 and the hot air flow generated therefrom, so that the aerosol product 300 generates an aerosol, which flows with the air flow to the suction port 122 of the tube body 12.

[0077] Among them, the aerosol product 300 and the cup body 11 of the heating non-burning device 100 can be detached and assembled, and can be disassembled and replaced according to the needs of use to meet the different taste requirements of users.

[0078] Furthermore, the heating non-burning system in this embodiment also has all the beneficial effects of the heating non-burning device in any of the first aspects described above, which will not be repeated here.

[0079] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
