Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to a heating non-combustible device and a heating non-combustible system. Background Technology

[0002] In related technologies, heated non-combustible devices are generally used to heat aerosol-generating products to produce aerosols. In the structure of heated non-combustible devices using natural smoke cigarettes (NSCS), the heating element contacts the outer surface of the aerosol-generating product. The tobacco heating area naturally generates aerosols under low-oxygen conditions. The aerosols diffuse into the aerobic area and are then extracted through an air intake at the downstream end of the aerosol-generating product.

[0003] During the heating process of aerosol-generated products, gaps exist around the aerosol-generated products and heating tubes, resulting in poor contact between the heating tubes and the aerosol-generated products and affecting their fixation. Simultaneously, during user suction, cold air can enter the heated non-combustible equipment through these gaps, affecting heat conduction and causing temperature deviations, which in turn leads to technical problems such as difficulty in controlling the equipment's power. Utility Model Content

[0004] This application provides a heat-not-burning device and a heat-not-burning system to solve the technical problem of difficult power control of the heat-not-burning device and the heat-not-burning system, and can control the actual temperature of the generated aerosol within a small error range from the required temperature.

[0005] In one embodiment, a heat-not-burning device is provided for heating an aerosol-generating product with an air inlet on its outer periphery;

[0006] The heated non-combustible device includes a main body and a sealing element. The main body has a heating chamber with one end open. The sealing element is detachably sealed to the open end of the heating chamber. The sealing element has a mounting hole that communicates with the heating chamber. The mounting hole allows the aerosol generating product to pass through and enter the heating chamber. The wall of the mounting hole seals the outer peripheral surface of the aerosol generating product, so that the air inlet is located outside the heated non-combustible device.

[0007] In one embodiment, at least one of the body and the seal has or is provided with a connection structure;

[0008] The connection structure includes an elastic snap-fit ​​part, which is located in one of the main body and the seal, and the other of the main body and the seal is engaged and fixed with the elastic snap-fit ​​part.

[0009] In one embodiment, the elastic snap-fit ​​part includes an annular base and a plurality of spring pieces. The first end of the spring piece is connected to the annular base, and the second end of the spring piece is closer to the center of the annular base than the inner circumferential surface of the annular base. The plurality of spring pieces are spaced apart along the circumference of the annular base. The annular base is installed on the main body, and the sealing element is inserted into the annular base and the main body. The second ends of the plurality of spring pieces are snapped onto the outer circumferential surface of the sealing element.

[0010] In one embodiment, the connection structure further includes a slot, which is located in the other of the main body and the seal, and the elastic buckle is engaged and fixed with the slot.

[0011] In one embodiment, the elastic buckle is an elastic protrusion formed on the outer periphery of the sealing ring, the slot is provided on the cavity wall of the heating cavity and communicates with the heating cavity, and the slot also has an opening facing the sealing element for the elastic protrusion to be inserted, the elastic protrusion and the slot correspond one-to-one and are interference fit.

[0012] In one embodiment, the sealing element includes a rigid body portion and a flexible sealing portion disposed at one end of the rigid body portion, a mounting hole penetrating the flexible sealing portion and the rigid body portion, the flexible sealing portion being inserted into the heating chamber, and the rigid body portion abutting against the end face of the main body.

[0013] The slot is located on the outer circumferential surface of the main body, and the opening of the slot is radially away from the center of the heating cavity. The elastic latch is a claw located on the rigid main body, and there are at least two claws. The claws have hooks for engaging the slot. The claws are distributed circumferentially along the mounting hole. Along the radial direction of the mounting hole, the claws are spaced apart from the flexible sealing part, and the hooks face the flexible sealing part.

[0014] In one embodiment, the main body is provided with a first guide hole that connects to the heating cavity in the radial direction. The elastic buckle part includes a first elastic member and a supporting member. Both the first elastic member and the supporting member are disposed in the first guide hole. One end of the first elastic member acts on the main body, and the other end of the first elastic member acts on the supporting member, driving the supporting member to extend into the heating cavity and elastically abut against the sealing member.

[0015] The connection structure also includes a drive assembly, which is located on the main body and contacts the abutment. The drive assembly can drive the abutment to overcome the force of the first elastic member and move away from the heating chamber so as to remove the seal.

[0016] In one embodiment, the main body is further provided with a second guide hole, which is located at one end of the main body along the axial direction of the heating cavity, and the second guide hole is connected to the first guide hole;

[0017] The driving assembly includes a second elastic element and a driving element. The driving element is inserted into the second guide hole. One end of the second elastic element acts on the main body, and the other end of the second elastic element acts on the driving element. The driving element and the supporting element are provided with matching wedge surfaces. Under the drive of external force, the driving element can move in the direction of penetrating the first guide hole and drive the supporting element to move away from the heating cavity under the action of the wedge surface. The second elastic element is used to reset the driving element after the external force is removed.

[0018] In one embodiment, the heated non-combustible device further includes a heating element for heating the aerosol-generating article, the heating element being disposed within a heating chamber, the heating element having a receiving hole for inserting the aerosol-generating article, and a sealing element being disposed at one axial end of the heating element and located outside the receiving hole.

[0019] In one embodiment, a heat-not-burning system is provided, including an aerosol generating article and the heat-not-burning device described in the above embodiment. The aerosol generating article includes a matrix section and a cooling section and a filter section located downstream of the matrix section in sequence. At least one of the cooling section and the filter section has an air inlet on its outer periphery. The matrix section can be inserted into a heating chamber and heated to generate aerosol. A sealing element forms a seal with the outer peripheral surface of the aerosol generating article, and the air inlet is located outside the heat-not-burning device. Outside air can enter the aerosol generating article through the air inlet and carry away the aerosol generated by the matrix section.

[0020] According to the heated non-combustible device of the above embodiment, the air inlet is directly formed on the aerosol generating product. After the aerosol generating product is installed in place, the air inlet is directly connected to the outside. The aerosol generating product has a matrix section inserted into the heating chamber of the main body. When the matrix section of the aerosol generating product is heated, it can generate aerosol. There is a certain distance between the air inlet and the matrix section of the aerosol generating product. When the user inhales, outside air enters the aerosol generating product through the air inlet on the aerosol generating product. The heated aerosol mixes with the incoming air on its way to the user's mouth, allowing the aerosol to cool to a suitable temperature before being inhaled by the user.

[0021] By incorporating a detachable seal that can be assembled with the main body, the seal can form a tight seal with the wall of the heating chamber and the outer surface of the aerosol-generating product. External air cannot enter the heating chamber through the gap between the main body and the aerosol-generating product. This ensures that the temperature difference between the actual temperature of the matrix section of the aerosol-generating product and the heating temperature supplied by the non-combustible heating device can be kept within a small range, solving the technical problem of power control difficulties. Furthermore, the seal can be removed from the main body for easy replacement. After removal, the user can directly clean the heating chamber and the seal, which helps ensure reliable sealing during use. Attached Figure Description

[0037] 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.

[0038] 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.

[0039] 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).

[0040] This application provides a heating non-combustible device for heating an aerosol generating product with an air inlet on its outer periphery, so that the aerosol matrix inside the aerosol generating product forms an aerosol.

[0041] Please refer to Figures 1-12 The heated non-combustible device 100 includes a main body 110 and a sealing element 120. The main body 110 has a heating chamber 111 with one end open. The sealing element 120 is detachably sealed to the open end of the heating chamber 111. The sealing element 120 has a mounting hole 121 communicating with the heating chamber 111. The mounting hole 121 allows the aerosol generating product 200 to pass through and enter the heating chamber 111. The hole wall of the mounting hole 121 seals the outer peripheral surface of the aerosol generating product 200. The air inlet of the aerosol generating product 200 is located outside the heated non-combustible device 100 so that outside air can enter the interior of the aerosol generating product 200 through the air inlet of the aerosol generating product 200.

[0042] A detachable connection is formed between the main body 110 and the seal 120. In other words, the main body 110 and the seal 120 are connected in the first state, and detached from each other in the second state. The first state is the state of normal assembly, awaiting installation of the aerosol-generated product 200, and the second state is the unassembled state. For example, see reference... Figure 4 and Figure 5 , Figure 6 and Figure 7 .

[0043] Compared to the heated non-combustible device 100 in related technologies, the heated non-combustible device 100 of this embodiment does not have an air inlet on the main body 110. Instead, the air inlet is directly formed on the aerosol generating product 200. After the aerosol generating product 200 is installed, the air inlet is located outside the heated non-combustible device and directly connected to the outside. The matrix section 230 of the aerosol generating product 200 is inserted into the heating chamber 111 of the main body 110. Along the aerosol flow direction when the user inhales, the matrix section 230 of the aerosol generating product 200 is upstream of the aerosol generating product 200, the air inlet of the aerosol generating product 200 is downstream of the matrix section, and the filter section 250 on the aerosol generating product 200 is downstream of the air inlet.

[0044] When the user inhales, the aerosol is heated by the heating non-combustible device 100, and aerosol can be generated in the matrix section 230 of the aerosol generating product 200. Outside air enters the aerosol generating product 200 through the air inlet on the aerosol generating product 200. The generated aerosol mixes with the air on its way to the user's mouth, so that the aerosol is cooled to a suitable temperature and finally inhaled by the user.

[0045] By providing a seal 120 that is detachably assembled with the main body 110, on the one hand, the seal 120 can simultaneously form a sealing fit with the cavity wall of the heating chamber 111 of the main body 110 and the outer peripheral surface of the aerosol generating product 200. External air cannot enter the heating chamber 111 through the gap between the main body 110 and the aerosol generating product 200, thus preventing the temperature of the matrix section 230 of the aerosol generating product from dropping. This helps to control the temperature difference between the actual temperature of the heating area of ​​the aerosol generating product and the heating temperature of the heating non-combustible device 100 within a small range, ensuring that the actual heating curve of the heating non-combustible system 1000 is basically consistent with the ideal heating curve, solving the technical problem of difficult power control. On the other hand, the seal 120 can be removed from the main body 110, facilitating the replacement of the seal 120. After removing the seal 120, the user can directly clean the heating chamber 111 of the main body 110 and the seal 120, which effectively helps to ensure the reliability of the seal during use.

[0046] It should be noted that this application does not limit the structure of the main body 110 and the sealing element 120 or the specific scheme of the detachable connection. It can be any feasible quick-release assembly scheme in the related technology, as long as it can realize the assembly and disassembly of the main body 110 and the sealing element 120.

[0047] In one embodiment, please refer to Figures 3-12 To facilitate assembly and disassembly, at least one of the main body 110 and the seal 120 has or is provided with a connecting structure, and the main body 110 and the seal 120 are detachably connected through the connecting structure. Here, "has or is provided with a connecting structure 130" means that in some embodiments, the connecting structure 130 can be an independent component, mechanically connected to the corresponding main body 110 or seal 120, corresponding to the aforementioned "provided". In other embodiments, the connecting structure 130 can also be a component, that is, a part of the corresponding main body 110 or seal 120, corresponding to the aforementioned "has". "At least one of the main body 110 and the seal 120 has or is provided with a connecting structure 130" includes several scenarios: the connecting structure 130 on the main body 110 is connected to the body of the seal 120, or the body of the main body 110 is connected to the connecting structure 130 on the seal 120, or the connecting structure 130 on the main body 110 is connected to the connecting structure 130 on the seal 120.

[0048] In one embodiment, please refer to Figures 3-12The connection structure 130 may include an elastic snap-fit ​​part 140, which is disposed on one of the main body 110 and the seal 120. The other of the main body 110 and the seal 120 is engaged and fixed with the elastic snap-fit ​​part 140. The elasticity of the elastic snap-fit ​​part 140 enables the assembly and disassembly of the seal more quickly and conveniently. At the same time, it can also enhance the connection stability between the main body 110 and the seal 120, so that the main body 110 and the seal 120 can remain relatively fixed, which helps to avoid sealing failure caused by changes in the relative position between the main body 110 and the seal 120.

[0049] In one embodiment, please refer to Figure 3 and Figure 4 The elastic snap-fit ​​part 140 includes an annular base 141 and a plurality of spring pieces 142. The first end of the spring piece 142 is connected to the annular base 141, and the second end of the spring piece 142 is closer to the center of the annular base 141 than the inner circumferential surface of the annular base 141. The plurality of spring pieces 142 are spaced apart along the circumference of the annular base 141. The annular base 141 is installed on the main body 110. The sealing member 120 is inserted into the annular base 141 and the main body 110, and the second ends of the plurality of spring pieces 142 are held on the outer circumferential surface of the sealing member 120. During the process of inserting or removing the seal 120 into or out of the heating cavity 111 of the main body 110, the spring piece 142 contacts the outer surface of the seal 120 and is slightly deformed in the direction away from the seal 120 due to the compression of the seal 120. After the seal 120 is installed in place, the seal 120 contacts the spring piece 142 and the cavity wall of the heating cavity 111. Multiple spring pieces 142 hug the seal 120 spring piece 142 ring in the radial direction of the seal 120. There is a certain static friction between the spring piece 142 and the seal 120, which can enhance the connection stability between the main body 110 and the seal 120.

[0050] In one embodiment, please refer to Figures 5-12 The connecting structure 130 also includes a slot 150, which is located in the other of the main body 110 and the seal 120. The elastic snap-fit ​​portion 140 is engaged and fixed with the slot 150. By adding a slot 150 that matches the elastic snap-fit ​​portion 140, the slot 150 can limit the seal 120 in the direction in which the seal 120 moves away from the main body 110, thereby increasing the connection stability between the seal 120 and the main body 110. When it is necessary to remove the seal 120 from the main body 110, the elastic snap-fit ​​portion 140 can be manually moved away from the slot 150.

[0051] In one embodiment, please refer to Figures 5-7The elastic buckle 140 is an elastic protrusion 143 formed on the outer periphery of the seal 120. The slot 150 is provided on the cavity wall of the heating cavity 111 of the main body 110 and communicates with the heating cavity 111. The slot 150 also has an opening facing the seal 120 for the elastic protrusion 143 to be inserted. The elastic protrusion 143 and the slot 150 correspond one-to-one and are interference-fitted. During the process of the seal 120 being inserted into the heating cavity 111 of the main body 110 and the seal 120 slidingly engaging with the main body 110, the elastic protrusion 143 is inserted into the slot 150 and slides with the slot 150. The seal 120 is a flexible and deformable component, and the elastic protrusion 143 is also elastic and deformable. The elastic protrusion 143 and the slot 150 are shaped and interference-fitted, allowing the user to easily disassemble or replace the seal 120.

[0052] In one embodiment, for ease of installation, the seal 120 and the elastic protrusion 143 can be made of a material with a high elastic coefficient. In order to make the seal 120 more securely installed on the main body 110, each groove surface of the slot 150 can be interference-fitted with the elastic protrusion 143, so that the elastic protrusion 143 cannot be dislodged from the slot 150 without a large external force.

[0053] In one embodiment, the seal 120 and the elastic protrusions 143 thereon can be made of a high-temperature resistant elastic material, thereby ensuring that the overall shape and size of the seal 120 remain basically unchanged after long-term use, thus improving the aging resistance of the seal 120 and extending its service life. The number of elastic protrusions 143 can be multiple, for example, 2 to 8, and the multiple elastic protrusions 143 are evenly distributed along the circumference of the seal 120 to ensure that the seal 120 is subjected to uniform force at all points after being installed on the main body 110.

[0054] In one embodiment, the elastic latch 140 can also be an elastic claw 144. One of the elastic claw 144 and the slot 150 is located on the main body 110, and the other of the elastic claw 144 and the slot 150 is located on the seal 120. The axial positioning between the main body 110 and the seal 120 is achieved by the cooperation of the elastic claw 144 and the slot 150, so as to restrict the seal 120 from detaching from the main body 110. When it is necessary to remove the seal 120 from the main body 110, the elastic claw 144 can be manually pried to disengage from the slot 150.

[0055] In one embodiment, please refer to Figure 8 and Figure 9The slot 150 is located on the outer peripheral surface of the main body 110. The opening of the slot 150 is radially away from the center of the heating cavity 111. The main body 110 is a rigid component. By opening the slot 150 on the outer surface of the main body 110, the slot 150 will not deform due to compression when it engages with the elastic snap-fit ​​part 140. In order to smoothly install the elastic snap-fit ​​part 140 on the sealing member 120, the sealing member 120 includes a rigid body part 122 and a flexible sealing part 123 located at one end of the rigid body part 122. The mounting hole 121 passes through the flexible sealing part 123 and the rigid body part 122. The flexible sealing part 123 is used to seal the gap between the main body 110 and the aerosol generating product 200. The elastic latching part 140 is a latch 144 provided on the rigid body part 122. There are at least two latches 144. The latches 144 have a certain elastic deformation capability. The latches 144 have hook parts 1441 for engaging the latching groove 150. The latches 144 are distributed circumferentially along the mounting hole 121. Along the radial direction of the mounting hole 121, the latches 144 are spaced apart from the flexible sealing part 123. The hook parts 1441 face the flexible sealing part 123, and the flexible sealing part 123 can be inserted. Located inside the heating chamber 111, the rigid body part 122 abuts against the end face of the main body 110, and the hook part 1441 extends into the slot 150 and engages with the slot 150 to restrict the axial movement of the seal 120 in the direction away from the main body 110. Since the slot 150 is exposed on the side of the main body 110, the claw 144 is also exposed, making it easy for the user to pry the claw 144 so that the hook part 1441 can be disengaged from the slot 150, and then the seal 120 can be moved away from the main body 110.

[0056] In one embodiment, please refer to Figures 10-12 The main body 110 is provided with a first guide hole 112 that connects to the heating cavity 111 in the radial direction. The elastic buckle part 140 includes a first elastic member 145 and a retaining member 146. Both the first elastic member 145 and the retaining member 146 are provided in the first guide hole 112. One end of the first elastic member 145 acts on the main body 110, and the other end of the first elastic member 145 acts on the retaining member 146. Under the elastic force of the first elastic member 145, the retaining member 146 extends into the heating cavity 111 and elastically abuts against the outer periphery of the sealing member 120, so as to position the sealing member 120 by the external force acting on the sealing member 120 in the radial direction, thereby enhancing the connection stability between the main body 110 and the sealing member 120.

[0057] Please refer to Figure 10The number of elastic buckle portions 140 can be multiple. At this time, the number of first guide holes 112 is also multiple. The multiple first guide holes 112 are evenly spaced apart. One elastic buckle portion 140 is provided in one first guide hole 112. Then, the multiple elastic buckle portions 140 evenly distributed in the circumference of the seal 120 stably hold the seal 120, so that the seal 120 is evenly stressed at all places after it is installed on the main body 110.

[0058] In one embodiment, please refer to Figure 11 and Figure 12 The connecting structure 130 also includes a driving assembly 160, which is located on the main body 110 and contacts the supporting member 146. The driving assembly 160 can drive the supporting member 146 to overcome the force of the first elastic member 145 and move away from the heating chamber 111 so as to remove the sealing member 120. At this time, there is no force or very little force between the supporting member 146 and the sealing member 120, and the user can easily remove the sealing member 120, thereby achieving quick disassembly of the main body 110 and the sealing member 120.

[0059] The drive assembly 160 can be any feasible mechanical transmission scheme, such as a multi-link mechanism transmission scheme, a gear and rack transmission scheme, etc. The mechanical connection transmission scheme has a simple structure and is easy for users to operate.

[0060] In one embodiment, please refer to Figure 11 and Figure 12 The main body 110 is also provided with a second guide hole 113, which is located at one end of the main body 110 along the axial direction of the heating cavity 111 and is connected to the first guide hole 112. The driving assembly 160 includes a second elastic member 161 and a driving member 162. The driving member 162 is inserted into the second guide hole 113. One end of the second elastic member 161 acts on the main body 110, and the other end of the second elastic member 161 acts on the driving member 162. The second elastic member 161 is used to reset the driving member 162 after the external force is removed. The driving member 162 and the supporting member 146 are provided with matching wedge surfaces. Under the drive of external force, the driving member 162 can move in the direction of penetrating the first guide hole 112 and drive the supporting member 146 away from the heating cavity 111 under the action of the wedge surfaces. By utilizing the interlocking of the wedge surfaces, the movement of the drive member 162 can be controlled to drive the abutment member 146 to move away from the heating chamber 111 against the force of the first elastic member 145, thereby causing the abutment member 146 to disengage from the seal member 120. After the external force applied to the drive member 162 is removed, the abutment member 146 and the drive member 162 can be reset under the action of the first elastic member 145 and the second elastic member 161, so that the abutment member 146 returns to its initial position inside the heating chamber 111.

[0061] In one embodiment, please refer to Figure 11 and Figure 12 The sealing element 120 is a rigid component. The connecting structure 130 also includes a groove 150 on the outer wall of the sealing element 120. The supporting member 146 is inserted into the groove 150. The groove 150 on the outer side of the rigid sealing element 120 prevents deformation due to compression when it engages with the supporting member 146, ensuring alignment between the supporting member 146 and the groove after assembly. The mounting hole 121 of the sealing element 120 has a flexible annular protrusion 124 on its wall. The annular protrusion 124 can be formed on the rigid sealing element 120 using any feasible method from related technologies, such as adhesive bonding or injection molding; this embodiment is not limited to any particular method. The annular protrusion 124 forms a sealing fit with the outer peripheral surface of the aerosol generating product 200, and the seal 120 and the main body 110 are basically sealed. The annular protrusion 124 plays the main sealing role. When the user inhales the aerosol, the outside air can only enter the aerosol generating product 200 through the air inlet 210, thereby achieving a better sealing effect.

[0062] In one embodiment, the connecting structure 130 may further include a first threaded portion and a second threaded portion. The first threaded portion is disposed on the main body 110, and the second threaded portion is disposed on the seal 120. The first threaded portion and the second threaded portion are connected to fix the main body 110 and the seal 120. That is, the main body 110 and the seal 120 are detachably connected by a threaded connection. Rotating the seal 120 in the forward direction will cause the second threaded portion on the seal 120 to gradually engage with the first threaded portion on the main body 110. Rotating the seal 120 in the reverse direction will remove the seal 120 from the main body 110.

[0063] In one embodiment, please refer to Figure 5 and Figure 6 A flexible annular protrusion 124 may also be provided on the wall of the mounting hole 121 of the seal 120, and the annular protrusion 124 seals the gap between the wall of the mounting hole 121 and the aerosol generating product 200.

[0064] In one embodiment, in order to solve the problem of weakened sealing effect caused by the detachable connection between the main body 110 and the sealing element 120, the heated non-combustible device 100 may further include a sealing gasket disposed between the sealing element 120 and the main body 110. The thickness of the sealing gasket may be 0.1mm to 1mm, and the material of the sealing gasket may be high-temperature resistant rubber or any other feasible material to ensure the sealing effect.

[0065] In one embodiment, please refer to Figure 2 , Figure 6 and Figure 11The heated non-combustible device 100 also includes a heating element 170, which is disposed within the heating chamber 111. The heating element 170 has a receiving hole 171 for inserting the aerosol generating article 200. The heating element 170 is used to heat the inserted heated aerosol generating article 200. A sealing element 120 is disposed at one axial end of the heating element 170 and located outside the receiving hole 171, so that the sealing element 120 does not extend into the direct heating area of ​​the heating element 170, effectively preventing the sealing element 120 from being heated to a high temperature, thereby effectively extending the service life of the sealing element 120.

[0066] In one embodiment, please refer to Figure 6 The heating element 170 is in the shape of a round tube. Its receiving hole 171 and the mounting hole 121 of the sealing element 120 are both round holes that match the shape of the aerosol generating article 200. The hole wall of the mounting hole 121 can be aligned with the hole wall of the receiving hole 171. Only the annular protrusion 124 protrudes slightly inward to abut and seal the outer peripheral surface of the aerosol generating article 200.

[0067] Based on the same concept, this application also provides a heat-not-burning system 1000, including an aerosol generating article 200 and the heat-not-burning device 100 in the above embodiments. Please refer to... Figure 1 and Figure 2 The aerosol generating product 200 includes a matrix section 230 and a cooling section 240 and a filter section 250 located downstream of the matrix section 230. At least one of the cooling section 240 and the filter section 250 has an air inlet 210 on its outer periphery. The matrix section 230 can be inserted into the heating chamber 111 and heated to generate aerosol. The sealing member 120 forms a seal with the outer peripheral surface of the aerosol generating product 200, and the air inlet 210 is located outside the heating non-combustible device 100. Outside air can enter the aerosol generating product 200 through the air inlet 210 and carry out the aerosol generated by the matrix section 230 when the user evacuates.

[0068] The interior of the substrate segment 230 has a porous and breathable structure. The substrate segment 230 can be made from tobacco or non-tobacco plants, such as tea leaves. The substrate segment 230 can generate aerosols when heated.

[0069] The cooling section 240 can cool the flowing aerosol. The specific method by which the cooling section 240 achieves cooling is not limited in this embodiment. For example, in some embodiments, it can be achieved by extending the flow path of the aerosol in the cooling section 240, or the cooling section 240 can incorporate elements or materials with cooling functions. Those skilled in the art can make adaptive adjustments according to actual needs. The filter section 250 has an internally permeable structure, such as cellulose acetate or polypropylene fiber.

[0070] In one embodiment, please refer to Figure 1 and Figure 2 The cooling section 240 is a pipe section, and at least part of the cooling section 240 is located outside the heating non-combustible device 100. The filter section 250 is entirely located outside the heating non-combustible device 100. The air inlet is located on the cooling section 240 to utilize air to cool the aerosol.

[0071] In one embodiment, please refer to Figure 1 and Figure 2 The aerosol generating product 200 may also have a plug section 220, which is connected to the end of the matrix section 230 away from the cooling section 240 and the filter section 250. The plug section 220 is used to seal the end of the matrix section 230 away from the cooling section 240 and the filter section 250. The plug section 220 can be made of high-density plant fiber or other airtight or low-permeability materials to achieve an airtight or essentially airtight effect, so that the air intake of the aerosol generating product 200 is only achieved through the air inlet 210, thereby achieving NSCS. In addition, the plug section 220 can also prevent aerosol condensate or matrix residue from falling into the heating chamber 111, which is beneficial to the cleaning and normal use of the heated non-combustible device 100.

[0072] It should be noted that since the sealing element 120 can already enable the aerosol generating product 200 to only enter through the air inlet 210, in some embodiments, the aerosol generating product 200 may not have the plug section 220. However, having the plug section 220 can reduce the impact of aerosol condensate or matrix residue on the heating non-combustible device 100, and eliminate the need for subsequent cleaning of the heating chamber 111.

[0073] For any structural or functional components of the heated non-combustible device 100 and the heated non-combustible system 1000 that are not mentioned or described in detail, please refer to relevant technologies. For example, the power supply used to supply power to the heated non-combustible device 100 in the heated non-combustible system 1000, etc., will not be described in detail in the embodiments of this application.

[0074] In summary, the heating non-combustible device 100 and the heating non-combustible system 1000 provided in this application have at least the following beneficial effects:

[0075] By providing a seal 120 that is detachably assembled with the main body 110, on the one hand, the seal 120 can form a sealed fit with the cavity wall of the heating chamber 111 of the main body 110 and the outer peripheral surface of the aerosol generating product 200. External air cannot enter the heating chamber 111 through the gap between the main body 110 and the aerosol generating product 200. The temperature of the matrix section 230 of the aerosol generating product 200 is basically unaffected by the external environment. The temperature difference between the actual temperature of the matrix section 230 and the heating temperature of the heating non-combustible device 100 can be controlled within a small value, so that the actual heating curve of the heating non-combustible system 1000 is basically consistent with the ideal heating curve, thus solving the technical problem of difficult power control. On the other hand, the seal 120 can be removed from the main body 110, which facilitates the replacement of the seal 120. After removing the seal 120, the user can directly clean the heating chamber 111 of the main body 110 and the seal 120, which helps to ensure the reliability of the seal during use.

[0076] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
