[0002] This application claims priority to Chinese Patent Application No. 2024110446296, filed on July 31, 2024, entitled "Heated Non-combustible Aerosol Generating Device and Heated Non-combustible System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of heat-not-burning technology, specifically to a heat-not-burning aerosol generating device and a heat-not-burning system. Background Technology

[0004] Aerosol generators that use a heating-non-combustion method typically have a accommodating cavity for inserting aerosol products. The aerosol products also have a filtration section, a cooling section, and a matrix section. During the insertion of the aerosol product into the accommodating cavity, the heating needle of the aerosol generator is inserted into the matrix section of the aerosol product. In subsequent use, the matrix section can be heated directly to generate aerosol for the user.

[0005] After the effective substances in the matrix section are consumed, the aerosol product needs to be removed from the containment cavity. During the removal process, debris and other residues are easily generated in the containment cavity. These residues adhere to the heating needle and the cavity wall, making them inconvenient to clean. Summary of the Invention

[0009] A receiving chamber has an installation cavity and an air inlet communicating with the installation cavity. The air inlet is located on the outer peripheral surface of the receiving chamber. The installation cavity is used to install aerosol products. The receiving chamber is movably or detachably installed in the side recess. The receiving chamber has an installation position and a working position. When the receiving chamber is in the working position, the air inlet is sealed and connected to the gas outlet, and the installation cavity is communicating with the aerosol outlet. When the receiving chamber is in the installation position, the installation cavity is located outside the side recess.

[0010] In one embodiment, the containment chamber has a mezzanine space surrounding the mounting cavity, the mezzanine space connecting the air inlet and the mounting cavity.

[0011] In one embodiment, the mounting cavity extends in the first direction; one end of the mounting cavity away from the aerosol outlet in the first direction is connected to the interlayer space, and the other end is used to connect to the aerosol outlet when the mounting cavity is in the working position.

[0012] In one embodiment, the receiving chamber includes a receiving shell and a receiving cylinder, the receiving cylinder being disposed inside the receiving shell, the air inlet being located on the receiving shell, the interlayer space being located between the receiving shell and the receiving cylinder, and the mounting cavity being located inside the receiving cylinder;

[0013] The accommodating cylinder has an open end and a closed end located at both ends in the first direction. The open end is connected to the accommodating shell and is used to communicate with the aerosol outlet. The closed end is arranged at a distance from the accommodating shell and has a first inlet communicating with the interlayer space and the mounting cavity.

[0014] In one embodiment, the closed end is located on the side of the air inlet opposite to the aerosol outflow channel in the first direction, and a second inlet communicating between the interlayer space and the mounting cavity is provided on the side wall of the accommodating cylinder.

[0015] In one embodiment, there are multiple second inlets, each of which is arranged circumferentially around the mounting cavity.

[0016] In one embodiment, the opening diameter of the second inlet is smaller than the opening diameter of the first inlet; or, the total opening area of ​​the second inlet is smaller than the total opening area of ​​the first inlet.

[0017] In one embodiment, there are multiple mounting cavities, with adjacent mounting cavities spaced apart in the circumferential direction of the receiving chamber; when the receiving chamber is in the working position, only one mounting cavity connects the air inlet and the aerosol outlet.

[0018] In one embodiment, there are multiple air inlets, each mounting cavity is connected to one air inlet, and two adjacent air inlets are arranged at intervals in the circumferential direction of the containment chamber; when the containment chamber is in the working position, one of the air inlets is connected to the aerosol outlet through the corresponding mounting cavity.

[0027] 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.

[0028] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0029] 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).

[0030] This application provides a heated non-combustible aerosol generator to solve the problem in existing aerosol generators where debris generated on the heating needle and the cavity wall of the receiving chamber after removing the aerosol product 3 is inconvenient to clean.

[0031] Please refer to Figures 1 and 2. The heated non-combustible aerosol generator (hereinafter referred to as the aerosol generator) of this application includes a main unit 1 and a housing 2. The main unit 1 includes a heating element 11. The main unit 1 has an air inlet channel 12 and an aerosol outlet channel 14 extending in a first direction. The first direction can be understood as the height direction or the up-down direction when the aerosol generator is in use. The heating element 11 can be disposed in the air inlet channel 12. The heating element 11 can heat the airflow flowing through the heating element 11 in the air inlet channel 12. Multiple through holes can be provided on the heating element 11. When the airflow passes through the through holes of the heating element 11, it receives the heat of the heating element 11 to form a hot airflow.

[0032] The main unit 1 has a side recess 16, which can be understood as a notch on the side of the aerosol generator when in use. The bottom wall of the side recess 16 extends in a first direction. The side recess 16 may have two side walls arranged in the vertical direction to facilitate the machining of the outer contour of the entire main unit 1. The aerosol outlet channel 14 is located on the upper side of the side recess 16. The side wall on the upper side of the side recess 16 has an aerosol outlet 15 that communicates with the aerosol outlet channel 14. The bottom wall of the side recess 16 has a gas outlet 13 that communicates with the air inlet channel 12.

[0033] As in one embodiment, referring to Figure 2, the air intake channel 12 can be located on one side of the side recess 16 in the horizontal direction, that is, the arrangement direction of the air intake channel 12 and the side recess 16 is perpendicular to the first direction. This helps to reduce the size of the entire aerosol generator in the first direction and helps to achieve the miniaturization design of the entire aerosol generator. Alternatively, the air intake channel 12 can be set as a straight structure, with the extension direction of the air intake channel 12 perpendicular to the first direction. This can reduce the length of the air intake channel 12, that is, reduce the flow path of the hot air and reduce heat loss. Or in other embodiments, in order to avoid the installation of other structures such as the battery cell 4 on the host 1, the air intake channel 12 can be set as a bent structure, or the extension direction of the straight air intake channel 12 can be set to have an angle of less than 90° with the first direction.

[0034] The receiving chamber 2 is movably or detachably installed within the side recess 16. The receiving chamber 2 has an installation position and a working position. When in the installation position, the receiving chamber 2 is located outside the side recess 16; when in the working position, the receiving chamber 2 is located within the side recess 16. In one embodiment, one of the receiving chamber 2 and the main unit 1 has a sliding groove extending in a horizontal direction perpendicular to the first direction, and the other has a slider. The sliding groove and the slider cooperate to facilitate the installation and removal of the receiving chamber 2 within the side recess 16 of the main unit 1. A limiting protrusion can be provided at one end of the sliding groove to prevent the receiving chamber 2 from dislodging from the side recess 16 when the receiving chamber 2 is in the working position, through an interference fit between the limiting protrusion and the slider. In another embodiment, the receiving chamber 2 can be rotatably mounted within the side recess 16 via a rotating shaft. The rotating shaft is rotatably mounted on the side wall of the side recess 16, and the receiving chamber 2 can rotate around the rotating shaft to switch between the working position and the installation position.

[0035] The outer contour shape of the containment chamber 2 can be generally cylindrical or other irregularly shaped structures that fill the side recess 16. The containment chamber 2 has a mounting cavity 225 and an air inlet 211 communicating with the mounting cavity 225. The air inlet 211 can be provided on the outer peripheral surface of the containment chamber 2. The outer peripheral surface of the containment chamber 2 can be understood as the cylindrical surface of the cylindrical structure of the containment chamber 2, or it can also be understood as the outer contour surface of the containment chamber 2 extending along the first direction. The mounting cavity 225 of the containment chamber 2 is used to install the aerosol product 3. The aerosol product 3 is detachably installed in the mounting cavity 225. When the containment chamber 2 is in the installation position, the aerosol product 3 can be removed from the mounting cavity 225.

[0036] When the containment chamber 2 is in the working position, it is located within the side recess 16, with its walls fitting against the side walls of the recess 16. This ensures that the opening of the mounting cavity 225 corresponds to and communicates with the aerosol outlet 15 of the main unit 1. The air inlet 211 of the containment chamber 2 is sealed to the gas outlet 13 of the main unit 1. A sealing groove 131 can be provided on the main unit 1, surrounding the gas outlet 13. A sealing ring 132 is installed within the sealing groove 131. When the containment chamber 2 is in the mounting position, the sealing ring 132 protrudes from the opening of the sealing groove 131. When the containment chamber 2 is in the working position, the sealing ring 132 is squeezed and deformed by the containment chamber 2 to achieve a sealed connection between the air inlet 211 on the containment chamber 2 and the gas outlet 13 of the main unit 1. When the containment chamber 2 is in the working position, the hot air flow formed by the heating element 11 flowing through the air inlet channel 12 enters the mounting cavity 225 of the containment chamber 2 from the gas outlet 13 and the air inlet 211, heating the aerosol product 3 to generate aerosol. The aerosol enters the aerosol outlet 15 of the main unit 1 from the mounting cavity 225 and is sucked out of the main unit 1 along the aerosol outflow channel 14.

[0037] In the aerosol generating device disclosed in this application embodiment, the heating element 11 is disposed on the main unit 1, and the aerosol product 3 is heated by a hot airflow. This avoids direct contact between the heating element 11 and the aerosol product, and prevents the generation of debris or other residues on the heating element 11 when the aerosol product 3 is removed. Furthermore, the receiving chamber 2, on which the aerosol product 3 is installed, is movably or detachably installed in the side recess 16 of the main unit 1. The user can remove the aerosol product when the receiving chamber 2 is in the installation position and the entire receiving chamber 2 and the installation cavity 225 are outside the side recess 16. This facilitates the cleaning of the entire receiving chamber 2 and the installation cavity 225, and avoids the condensate residue formed by the backflow of aerosol in the installation cavity 225, thus improving the user experience.

[0038] In one embodiment, referring to Figure 2, the receiving chamber 2 may be provided with a mezzanine space 23 surrounding the mounting cavity 225. The mezzanine space 23 is arranged around the mounting cavity 225 and connects the air inlet 211 and the mounting cavity 225. The hot airflow entering the receiving chamber 2 from the air inlet 211 first enters the mezzanine space 23. By storing part of the hot airflow in the mezzanine space 23, on the one hand, the mezzanine space 23 can serve as a buffer space to ensure continuous air supply in the mounting cavity 225. The mezzanine space 23 can also serve as a heat insulation space to reduce the heat transfer of the hot airflow outward. On the other hand, the hot airflow in the mezzanine space 23 can preheat the aerosol product 3 in the mounting cavity 225 to accelerate the aerosol generation rate during the initial use of the aerosol product 3.

[0039] In another embodiment, the interlayer space 23 can be omitted, and the internal space of the containment chamber 2 can be set to form an installation cavity 225. The air inlet 211 of the containment chamber 2 is directly connected to the installation cavity 225, and the opening of the installation cavity 225 is connected to the aerosol outlet 15 when the containment chamber 2 is in the working position.

[0040] In some embodiments, in order to achieve sufficient heating of the aerosol product 3 and increase the contact area between the hot airflow and the aerosol product 3, please continue to refer to FIG2, the mounting cavity 225 is configured such that one end of its extension direction is connected to the interlayer space 23, and the other end is connected to the aerosol outlet 15 when the receiving chamber 2 is in the working position; furthermore, in order to facilitate the installation of the receiving chamber 2 in the aerosol generating device, the mounting cavity 225 can be arranged to extend in the first direction; of course, in other embodiments, under the condition of sufficient installation space, the extension direction of the mounting cavity 225 can also be set to be perpendicular to the first direction. In an embodiment where the mounting cavity 225 extends in the first direction, the end of the mounting cavity 225 near the aerosol outlet channel 14 in the first direction is connected to the aerosol outlet 15 when the receiving chamber 2 is in the working position, and the end away from the aerosol outlet channel 14 is connected to the interlayer space 23. In this way, the hot airflow entering the interlayer space 23 from the air inlet 211 enters the mounting cavity 225 from the bottom in the first direction, heats the aerosol product 3, and causes the generated aerosol to enter the aerosol outlet channel 14 from the opening at the top of the mounting cavity 225.

[0041] As in one embodiment, referring to Figure 2, the receiving chamber 2 may include a receiving shell 21 and a receiving cylinder 22. The receiving shell 21 is generally a cylindrical shell structure extending in a first direction. The receiving cylinder 22 is located inside the receiving shell 21 and extends in the first direction. An air inlet 211 is located on the receiving shell 21, and a sandwich space 23 is located between the receiving shell 21 and the receiving cylinder 22. The receiving cylinder 22 has an open end 221 and a closed end 222 located at both ends in the first direction. The internal space of the receiving cylinder 22 forms an installation cavity 225. The open end 221 of the receiving cylinder 22 is located between its closed end 222 and the aerosol outlet 15. The open end 221 of the receiving cylinder 22 is connected to the end of the receiving shell 21 near the aerosol outlet 15 in the first direction. When the receiving chamber 2 is in the working position, the open end 221 of the receiving cylinder 22 corresponds to and communicates with the aerosol outlet 15, allowing air to pass through the aerosol outlet of the main unit 1. A sealing ring is provided around the opening 15. When the receiving chamber 2 is in the working position, the sealing ring is squeezed by the opening edge of the receiving cylinder 22 to achieve a sealed connection between the opening of the receiving cylinder 22 and the aerosol outlet 15. The end face of the closed end 222 can be spaced apart from the receiving shell 21 in the first direction. The mounting cavity 225 is connected to the interlayer space 23 at the closed end 222 of the receiving cylinder 22. A first inlet 223 can be provided on the end face of the closed end 222 so that the interlayer space 23 is connected to the mounting cavity 225 through the first inlet 223.

[0042] In other embodiments, the end face of the closed end 222 of the accommodating cylinder 22 can be fitted with the housing 21; or both ends of the accommodating cylinder 22 in the first direction are open ends, wherein the open end near the aerosol outlet 15 is connected to the housing 21, and the open end away from the aerosol outlet 15 is fitted with the housing 21. In these embodiments, the first inlet 223 can be set on the outer peripheral surface of the end of the accommodating cylinder 22 away from the aerosol outlet 15 in the first direction. After the aerosol product 3 is installed in the mounting cavity 225, the aerosol product 3 and the first inlet 223 are arranged in the first direction. The hot airflow entering the mounting cavity 225 from the first inlet 223 can enter the aerosol product 3 along one end of the aerosol product 3 in the first direction to heat the aerosol product 3.

[0043] In some embodiments, referring to Figure 2, the closed end 222 of the accommodating cylinder 22 is positioned in the first direction on the side of the air inlet 211 on the housing 21 facing away from the aerosol outlet 15. This allows the hot airflow entering the interlayer space 23 from the air inlet 211 to first flow in the first direction away from the aerosol outlet 15 to the closed end 222 of the accommodating cylinder 22, and then enter the mounting cavity 225 along the first inlet 223. During this flow, the heat from the hot airflow is transferred along the cylinder wall of the accommodating cylinder 22 to the aerosol product 3, thus preheating the aerosol product 3 and reducing the waiting time for the aerosol product 3 to generate aerosol for the first time. In other embodiments, the closed end 222 of the accommodating cylinder 22 can also be positioned in the first direction between the air inlet 211 and the aerosol outlet 15 on the housing 21, or the closed end 222 can be positioned in the first direction corresponding to the position of the air inlet 211; these are also feasible.

[0044] To increase the air intake of the mounting cavity 225 per unit time and further shorten the waiting time for the aerosol product 3 to generate aerosol for the first time, in one embodiment, referring to Figure 2, a second inlet 224 connecting the interlayer space 23 and the mounting cavity 225 can be provided on the side wall of the accommodating cylinder 22. The second inlet 224 can be directly opposite the air inlet 211 on the housing 21, or the second inlet 224 and the air inlet 211 can be at the same height in the first direction. This can reduce the path length of the hot airflow from the air inlet 211 to the mounting cavity 225, thus shortening the waiting time for aerosol. The hot airflow passes through the aerosol product 3 from bottom to top through the first inlet 223, which can heat every part of the aerosol product 3 to generate aerosol. The hot airflow can also enter from all sides of the aerosol product 3 through the second inlet 224, which can further improve the heating sufficiency of the aerosol product 3 and increase the concentration of the first aerosol breath inhaled by the user.

[0045] In embodiments where a first inlet 223 and / or a second inlet 224 are provided on the accommodating cylinder 22, in order to increase the air intake of the mounting cavity 225 per unit time, multiple first inlets 223 and second inlets 224 are provided, such as two, three, or more than four. Two adjacent first inlets 223 are spaced apart on the end face of the closed end 222 of the accommodating cylinder 22, or two adjacent first inlets 223 are spaced apart circumferentially on the accommodating cylinder 22; two adjacent second inlets 224 are also spaced apart circumferentially on the accommodating cylinder 22. Alternatively, in other embodiments, the cylinder wall of the accommodating cylinder 22 can be directly configured as a hollow structure with multiple through holes, with the through holes on the end face of the closed end 222 forming the first inlet 223, and the through holes on the side wall of the accommodating cylinder 22 forming the second inlet 224.

[0046] In an embodiment where a first inlet 223 and a second inlet 224 are provided on the container cylinder 22, the first inlet 223 of the closed end 222 of the container cylinder 22 is the main air inlet with a large flow rate. The hot air flow for heating enters the aerosol product 3 from bottom to top, which can ensure the contact area between the aerosol product 3 and the hot air flow, and achieve sufficient heating of the aerosol product 3. The second inlet 224 is an auxiliary air inlet with a smaller flow rate. It can preheat the circumferential part of the aerosol product 3 with a small flow rate of hot air in advance, so that when the aerosol product 3 is heated by the hot air flow of the first inlet 223, aerosol can be generated more quickly. In one embodiment, there may be one first inlet 223 and one second inlet 224, and both the first inlet 223 and the second inlet 224 are circular holes, with the opening diameter of the first inlet 223 being larger than the opening diameter of the second inlet 224. In another embodiment, the shape and number of the first inlet 223 and the second inlet 224 are not limited, nor are the shape and size of each first inlet 223 or second inlet 224 required to be the same, as long as the total opening area of ​​the first inlet 223 is greater than the total opening area of ​​the second inlet 224.

[0047] In some embodiments, the housing 2 has multiple mounting cavities 225, and the number of aerosol products 3 in the aerosol generating device can be increased by loading multiple aerosol products 3 into the housing 2 at one time.

[0048] In one embodiment, the housing 2 has multiple mounting cavities 225, such as three, namely a first mounting cavity, a second mounting cavity, and a third mounting cavity. The housing 2 has only one air inlet 211, which is only connected to the first mounting cavity. When the housing 2 is in the working position, the air inlet 211 is connected to the aerosol outlet 15 through the first mounting cavity. The second and third mounting cavities can be used only as storage cavities for the aerosol product 3.

[0049] In the initial state, the aerosol generating device has three aerosol products 3: the first aerosol product is installed in the first mounting cavity, the second aerosol product is installed in the second mounting cavity, and the third aerosol product is installed in the third mounting cavity. Since only the first mounting cavity is connected to the air inlet 211 and the aerosol outlet 15, after the first aerosol product in the first mounting cavity is consumed, the second aerosol product in the second mounting cavity can be taken out and inserted into the first mounting cavity to heat the second aerosol product; after the second aerosol product is consumed, the third aerosol product in the third mounting cavity can be taken out and inserted into the first mounting cavity to heat the third aerosol product.

[0050] In another embodiment, referring to Figure 3, the housing 21 can also be set as a cylindrical housing, and the housing 21 has multiple air inlets 211. Multiple mounting cavities and multiple air inlets 211 are arranged at intervals in the circumferential direction of the housing 21. The housing 21 has a partition between two adjacent housing cylinders 22. The space between two adjacent partitions in the circumferential direction and between the housing cylinders 22 and the housing 21 forms a sandwich space 23. The number and position of the sandwich spaces 23 correspond one-to-one with the number and position of the housing cylinders 22 and the number and position of the air inlets 211. The air inlets 211 can communicate with the mounting cavities 225 in the corresponding housing cylinders 22 through the corresponding sandwich spaces 23.

[0051] When the containment chamber 2 is in the working position, only one mounting cavity 225 and the corresponding air inlet 211 connect the gas outlet 13 and the aerosol outlet 15. In this way, the containment chamber 2 has multiple working positions that connect different mounting cavities 225 to the air inlet 211 and the aerosol outlet 15. By rotating the containment chamber 2 around its central axis, the containment chamber 2 can be switched between different working positions, realizing the switching of different aerosol products 3 in different mounting cavities 225 between the air inlet 211 and the aerosol outlet 15. This satisfies the requirement that only one aerosol product 3 can participate in the aerosol generation work at a time. In this way, multiple aerosol products can be drawn after one filling, without the need to insert aerosol products after each drawing, and without frequently switching the containment chamber 2 to the mounting position. Different working positions and different aerosol products 3 can be changed directly when the containment chamber 2 is in the side recess 16.

[0052] Of course, in some other embodiments, only one air inlet 211 is provided on the housing 21, and multiple housing cylinders 22 are provided inside the housing 21. Multiple housing cylinders 22 can be rotatably installed inside the housing 21. Multiple housing cylinders 22 have operating ends that extend out of the housing 21. By moving the operating ends in the circumferential direction of the housing 21, different housing cylinders 22 can be aligned with the aerosol outlet 15 in the first direction. In this way, the aerosol product 3 can be replaced without frequently switching the position of the housing 2.

[0053] This application embodiment also provides a heat-not-burning system. Please refer to Figure 2. The heat-not-burning system includes the heat-not-burning aerosol generating device of any of the above embodiments, and also includes an aerosol product 3. The mounting cavity 225 in the aerosol generating device is a cylindrical cavity, and the aerosol product 3 is a cylindrical structure adapted to the shape of the mounting cavity 225. The aerosol product 3 and the mounting cavity 225 are interference-fitted, which can prevent the hot airflow from being sucked out of the aerosol outlet channel 14 in the mounting cavity 225 without passing through the aerosol product 3, thereby reducing the probability of the user being burned.

[0054] The aerosol product 3 includes an aerosol matrix made of a material capable of generating aerosols when heated. The aerosol matrix can be filamentous, sheet-like, or granular. The dimensions of the aerosol matrix in the first direction are equal to the dimensions of the aerosol product 3 in the first direction. Alternatively, in other embodiments, the dimensions of the aerosol product 3 in the first direction can be larger than the dimensions of the aerosol matrix in the first direction. The aerosol product 3 may also include a flavoring substance that can alter the aerosol odor to meet user needs and improve the user experience.

[0055] 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.
