Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to a heating structure and an aerosol generating device. Background Technology

[0002] In the field of atomization technology, aerosol generating devices heat and atomize an aerosol generating matrix through a heating structure, thereby generating aerosols from the matrix. Specifically, the heating component in the aerosol generating device radiates energy to the aerosol generating matrix to produce aerosols. To achieve automatic heating of the aerosol generating device, a detection component consisting of a pair of annular detection elements is provided at the initial and final ends of the insertion path of the aerosol generating matrix. During the insertion or removal of the aerosol generating matrix from the heating component, the capacitance value of the detection component changes. The relative positional relationship between the aerosol generating matrix and the heating component can be determined based on the change in the electrical signal characterizing the capacitance value. However, since the change in capacitance value of the detection component is usually small, the detection sensitivity is low, which may lead to slow detection or missed / false detections.

[0027] In the field of atomization technology, aerosol generating devices heat and atomize an aerosol generating matrix through a heating structure, thereby generating aerosols from the aerosol generating matrix. Specifically, the heating component in the aerosol generating device radiates energy to the aerosol generating matrix to produce aerosols. To achieve automatic heating, the heating component has a pair of annular detection elements at the initial and final ends of the insertion path of the aerosol generating matrix. During the insertion or removal of the aerosol generating matrix from the heating component, the capacitance value of the detection elements changes. The relative positional relationship between the aerosol generating matrix and the heating component can be determined based on the change in the electrical signal characterizing the capacitance value. However, since the change in capacitance value of the detection elements is usually small, the detection sensitivity is low, which may lead to slow detection or missed / false detections. To solve this problem, this application provides a heating structure 100 (… Figures 1 to 3 (as shown) and aerosol generating device 1000 ( Figure 7 (As shown).

[0028] Please refer to this as well. Figure 1and Figure 2 In a first aspect, this application provides a heating structure 100. The heating structure 100 includes a support 10, a heating element 30, and a detection element 70. The support 10 has a receiving cavity 11, an inlet 131, and an outlet 1511, with the inlet 131 and outlet 1511 located at opposite ends of the receiving cavity 11. The heating element 30 is housed within the receiving cavity 11, and the sidewalls of the heating element 30 form an atomizing cavity 311 that is open at both ends and communicates with the inlet 131 and outlet 1511, respectively. The heating element 30 and the support 10 together form a loading cavity 111, which includes at least the atomizing cavity 311 and is configured to house an aerosol generating matrix 20. The outlet 1511 is the inlet for the aerosol generating matrix 20 to be inserted into the loading cavity 111, and the heating element 30 is configured to heat the aerosol generating matrix 20 to generate aerosols. The detection element 70 is disposed on the support 10 and surrounds the loading cavity 111. Along the longitudinal direction Z of the heating structure 100, the detection assembly 70 includes a first detection element 731 and a second detection element 733 spaced apart from each other and opposite to each other. Multiple microcapacitors are formed between the first detection element 731 and the second detection element 733, and these microcapacitors are electrically connected and together form an equivalent capacitance. The detection assembly 70 is configured to output an electrical signal characterizing the capacitance value of the equivalent capacitance. This electrical signal is used to determine the insertion / removal state of the aerosol generation matrix 20 in the loading cavity 111.

[0029] Specifically, the aerosol generating device 1000 is an apparatus that loads an aerosol generating matrix 20 and heats it to generate aerosols. The aerosol generating matrix 20 can be pulverized into fine particles by heating or ultrasonic vibration and mixed with air to form an aerosol. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating matrix 20 can be in a liquid state or a solid state (including fully solid and semi-solid). In the embodiments of this application, the aerosol generating matrix 20 is a long strip-shaped solid, which is inserted into the heating structure 100 of the aerosol generating device 100 during use.

[0030] The heating structure 100 is a structure that acts to heat an object to be heated, so that it is at least partially heated and its temperature rises. In this application, the heating structure 100 is a structure used to heat the aerosol generating matrix 20 to generate aerosols. The heating structure 100 can use different heating methods to heat the aerosol generating matrix 20, and correspondingly, the heating structure 100 includes different structures. In some embodiments, when the heating structure 100 uses electromagnetic waves to heat the aerosol generating matrix 20, the heating structure 100 includes an electromagnetic coil that can radiate electromagnetic waves to heat the aerosol generating matrix 20 and generate aerosols. In other embodiments, when the heating structure 100 uses microwaves to heat the aerosol generating matrix 20, the heating structure 100 includes a microwave generator that can radiate microwaves to heat the aerosol generating matrix 20 and generate aerosols. In some embodiments, where the heating structure 100 uses laser heating to generate the aerosol-forming matrix 20, the heating structure 100 includes a laser emitter that emits laser light to heat the aerosol-forming matrix 20 and generate aerosols. In still other embodiments, where the heating structure 100 uses infrared light to heat the aerosol-forming matrix 20, the heating structure 100 includes a heating element, a heating component, and an infrared radiation layer. The heat generated by the heating component causes the infrared radiation layer to emit infrared light, thereby heating the aerosol-forming matrix 20 and generating aerosols. This application uses the heating structure 100 using infrared light to heat the aerosol-forming matrix 20 as an example.

[0031] The support 10 is a structure in the heating structure 100 used to house components other than the support 10. Components other than the support 10, as used herein, include, but are not limited to, the heating element 30 and the heat insulation element. The shape of the outer contour of the cross-section of the support 10, cut by a plane perpendicular to the length direction Z of the heating structure 100, can be regular or irregular. Regular shapes, as used herein, include, but are not limited to, rectangles, circles, ellipses, triangles, and rectangles. The accommodating cavity 11 is a spatial structure in the heating structure 100 used to house at least some of the components other than the support 10. The shape of the accommodating cavity 11 corresponds to the outer contour shape of the support 10. Furthermore, the connection between the support 10 and the heating element 30, and between the support 10 and the detection element 70, can be either detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of methods such as abutment, screw connection, and snap-fit ​​connection. Non-detachable connections include, but are not limited to, one or more combinations of methods such as gluing, welding, and sintering. This definition will be used for detachable and non-detachable connections in the following text, and will not be elaborated further. Inlet 131 is a spatial structure that provides a channel for external gas to enter the loading chamber 111, and outlet 1511 is a spatial structure that provides a channel for substances (such as generated aerosols) in the loading chamber 111 to flow to the outside. Inlet 131 and outlet 1511 are located at opposite ends of the loading chamber 111 so that the loading chamber 111 can allow substances to flow in or out smoothly.

[0032] The heating element 30 is the specific component in the heating structure 100 used to generate heat. The heating element 30 is housed within the receiving cavity 11, and the bracket 10 provides support and protection for its installation. The heating element 30 has an open structure at both ends, and the structure formed by the side walls of the heating element 30 is an atomizing cavity 311. The atomizing cavity 311 is a spatial structure with open ends, and these two ends are respectively connected to the inlet 131 and the outlet 1511, so that at least a portion of the aerosol generating matrix 20 extends into the atomizing cavity 311, and the atomizing cavity 311 allows gas to flow in or out. The loading cavity 111 is a spatial structure for loading the aerosol generating matrix 20. The loading cavity 111 is formed by the heating component 30 and the support 10. It can be understood that the loading cavity 111 includes at least the atomizing cavity 311. During the process of loading the aerosol generating matrix 20 into the loading cavity 111, the aerosol generating matrix 20 is inserted into the loading cavity 111 through the outlet 1511 and at least partially extends into the atomizing cavity 311. At this time, the heating component 30 can heat it to generate aerosol.

[0033] The detection component 70 is used to detect the relative positional relationship between the aerosol generating matrix 20 and the loading cavity 111. The detection component 70 is mounted on the bracket 10 so that it can surround the loading cavity 111. The connection between the detection component 70 and the bracket 10 can be detachable or non-detachable. The detection component 70 includes a first detection element 731 and a second detection element 733. Along the longitudinal direction Z of the heating structure 100, the first detection element 731 and the second detection element 733 are spaced apart and opposite to each other. At this time, at least a portion of the structure of the first detection element 731 and at least a portion of the structure of the second detection element 733 respectively corresponds to an electrode plate, and there is a certain gap between them. The air inside the gap can act as a dielectric, thus forming multiple microcapacitors between the first detection element 731 and the second detection element 733. The capacitance of each microcapacitor is determined by the effective area of ​​each opposite electrode plate, the electrode spacing, and the dielectric constant of the dielectric. In this application, "multiple" refers to one or more, including but not limited to two, three, and four, etc. This definition will not be repeated hereafter. The aforementioned microcapacitors are electrically connected to each other and together form an equivalent capacitance. The capacitance value of the equivalent capacitance is the sum of the capacitance values ​​of each microcapacitor. The capacitance value between the first detection element 731 and the second detection element 733 is amplified through the microcapacitors, and changes in the equivalent capacitance can be detected sensitively.

[0034] Furthermore, the detection component 70 can output an electrical signal, which can be a voltage signal or a current signal, and is used to characterize the capacitance value of the equivalent capacitance. During the insertion of the aerosol generating matrix 20 into the loading cavity 111, at least a portion of the aerosol generating matrix 20 passes through the detection component 70 and corresponds to the detection area of ​​the detection component 70. Since the dielectric constant of the aerosol generating matrix 20 is different from that of air, the capacitance value of each microcapacitor will change, and correspondingly, the capacitance value of the equivalent capacitance will also change. Since the electrical signal can characterize the capacitance value of the equivalent capacitance, the change in the electrical signal of the detection component 70 can be used to determine whether the aerosol generating matrix 20 has been inserted into the loading cavity 111. Correspondingly, during the process of the aerosol generating matrix 20 being pulled out of the loading cavity 111, the aerosol generating matrix 20 that originally corresponded to the detection area of ​​the detection component 70 disappears, leaving only air (which may contain aerosols). Similarly, since the dielectric constant of the aerosol generating matrix 20 is different from that of air (which may contain aerosols), the capacitance value of each microcapacitor will also change. Consequently, the capacitance value of the equivalent capacitor will also change. Since the electrical signal can characterize the capacitance value of the equivalent capacitor, the change in the electrical signal of the detection component 70 can also be used to determine whether the aerosol generating matrix 20 has been pulled out of the loading cavity 111.

[0035] In the heating structure 100 of this application, the heating component 30 heats the aerosol generating matrix 20 inserted into the loading cavity 111 to generate an aerosol for the user to inhale. A detection component 70 is provided along the insertion path of the aerosol generating matrix 20 into the loading cavity 111. The detection component 70 is arranged around the loading cavity 111. The equivalent capacitance formed by the microcapacitors of the first detection element 731 and the second detection element 733 changes during the insertion of the aerosol generating matrix 20 into the loading cavity 111, and outputs an electrical signal characterizing the capacitance value of the equivalent capacitance. This electrical signal can be used to determine the insertion / removal state of the aerosol generating matrix 20 relative to the loading cavity 111. The microcapacitors in the detection component 70 result in high detection sensitivity, rapid detection, and accurate detection results. Therefore, the configuration of the detection component 70 enables the aerosol generating device 1000 to accurately detect the insertion / removal state and to decide whether to start or stop heating based on the determination of the insertion / removal state.

[0036] Please refer to Figures 1 to 3 In some embodiments, in the insertion direction of the aerosol generating matrix 20, the aerosol generating matrix 20 sequentially includes a mouthpiece section 23, a medium section 21, and a plug section 25. The loading cavity 111 is provided with a plug area 1111 corresponding to the plug section 25 and a mouthpiece area 1113 corresponding to the mouthpiece section 23. The detection component 70 includes a first detection component 71. The bracket 10 is provided with a first mounting area 133, which corresponds to the plug area 1111 in the direction X perpendicular to the length of the heating structure 100. The first detection component 71 is disposed in the first mounting area 133 and configured to output a first electrical signal, which is used to determine whether the aerosol generating matrix 20 is inserted into the loading cavity 111.

[0037] Specifically, in the above embodiment, the aerosol generating matrix 20 can be divided into multiple regions according to its position and function. In the direction in which the aerosol generating matrix 20 is inserted into the aerosol generating device 1000, the aerosol generating matrix 20 sequentially includes a mouthpiece section 23, a medium section 21, and a plug section 25. The mouthpiece section 23, the medium section 21, and the plug section 25 each have different dielectric constants. The mouthpiece section 23 is the part of the aerosol generating matrix 20 that is in direct contact with the user's mouth and is responsible for outputting aerosols. The mouthpiece section 23 can be further subdivided into a cooling section 233 and a filtering section 231. The filtering section 231 is closer to the user's mouth and is used to absorb or block condensate from entering the mouth; the cooling section 233 is used to isolate high temperatures, cool the aerosols, and prevent burns to the mouth. The medium section 21 is the part of the aerosol generating matrix 20 that carries the matrix components capable of generating aerosols. The plug section 25 is the end of the aerosol generating matrix 20 that seals the medium section 21, preventing matrix leakage and fixing the internal structure.

[0038] Along the length direction Z, the loading cavity 111 can also be divided into multiple regions. When the aerosol generating matrix 20 is stably inserted into the loading cavity 111, the region corresponding to the plug section 25 is defined as the plug region 1111, and the region corresponding to the mouthpiece section 23 is defined as the mouthpiece region 1113. The plug region 1111 and the mouthpiece region 1113 are spaced apart from each other and opposite each other along the length direction Z. When the aerosol generating matrix 20 is stably inserted into the aerosol generating device 1000, the plug section 25 is housed in the plug region 1111, and the mouthpiece section 23 is housed in the mouthpiece region 1113.

[0039] The first detection component 71 is used to detect whether the aerosol generating matrix 20 is inserted into the plug area 1111. Specifically, the first detection component 71 determines whether the aerosol generating matrix 20 is inserted into the plug area 1111 by detecting whether the plug section 25 of the aerosol generating matrix 20 is inserted into the loading cavity 111. The first mounting area 133 is the area on the bracket 10 used to mount the first detection component 71. In the direction X perpendicular to the length of the heating structure 100, the first mounting area 133 and the plug area 1111 are opposite to each other and correspond to each other. At this time, during the process of the plug section 25 being inserted into the plug area 1111, the dielectric constant of the dielectric in the equivalent capacitance of the first detection component 71 located in the first mounting area 133 changes, and the equivalent capacitance value changes. Since the first detection component 71 outputs a first electrical signal representing the real-time equivalent capacitance value, if at a certain moment the first electrical signal output by the first detection component 71 changes compared to the previous moment, and this change exceeds a predetermined range, it can be determined that the aerosol generating matrix 20 has been inserted into the loading cavity 111. Conversely, if the first electrical signal output by the first detection component 71 remains unchanged, or the change does not exceed a predetermined range, it can be determined that the aerosol generating matrix 20 has not been inserted into the loading cavity 111. Therefore, the heating structure 100 of this application can determine whether the aerosol generating matrix 20 has been inserted into the loading cavity 111 by using the first electrical signal output by the first detection component 71.

[0040] In summary, the first detection component 71 is located in the first installation area 133 to detect whether the plug section 25 of the aerosol generating matrix 20 is inserted in the plug area 1111. When the aerosol generating matrix 20 is inserted into the loading cavity 111, the first electrical signal output by the first detection component 71 changes, and this change exceeds a predetermined range. Therefore, the first detection component 71 can sensitively detect whether the aerosol generating matrix 20 is inserted into the loading cavity 111, which facilitates subsequent control of the aerosol generating device 1000 to automatically start heating and improves the intelligence of the aerosol generating device 1000.

[0041] Please refer to Figures 1 to 3In some embodiments, the detection component 70 includes a second detection component 73, and the bracket 10 has a second mounting area 155, which corresponds to the mouthpiece area 1113 in the direction perpendicular to the length of the heating structure 100. The second detection component 73 is disposed in the second mounting area 155 and configured to output a second electrical signal, which is used to determine whether the aerosol generating matrix 20 has been pulled out of the loading cavity 111.

[0042] Specifically, in the above embodiment, the second detection component 73 is used to detect whether the aerosol generating matrix 20 is pulled out of the loading cavity 111. Specifically, the second detection component 73 detects whether the mouthpiece segment 23 of the aerosol generating matrix 20 is pulled out of the mouthpiece area 1113. The second mounting area 155 is the area on the bracket 10 used to mount the second detection component 73. In the direction X perpendicular to the length of the heating structure 100, the second mounting area 155 and the mouthpiece area 1113 are opposite to each other and correspond to each other. At this time, during the process of the mouthpiece segment 23 being pulled out of the mouthpiece area 1113, the dielectric constant of the dielectric in the equivalent capacitance of the second detection component 73 disposed in the second mounting area 155 changes, and the equivalent capacitance value changes. Since the second detection component 73 outputs a second electrical signal representing the real-time equivalent capacitance value, if at a certain moment the second electrical signal output by the second detection component 73 changes compared to the previous moment, and this change exceeds a predetermined range, it can be determined that the aerosol generating matrix 20 has been removed from the loading cavity 111. Conversely, if the second electrical signal output by the second detection component 73 does not change, or the change does not exceed a predetermined range, it can be determined that the aerosol generating matrix 20 has not been removed from the loading cavity 111. Therefore, the heating structure 100 of this application can determine whether the aerosol generating matrix 20 has been removed from the loading cavity 111 by using the second electrical signal output by the second detection component 73.

[0043] In summary, the second detection component 73 is disposed in the second mounting area 155 to detect whether at least a portion of the mouthpiece segment 23 of the aerosol generating matrix 20 is pulled out in the mouthpiece area 1113. When it is determined that the aerosol generating matrix 20 has been pulled out of the loading cavity 111, the second electrical signal output by the second detection component 73 changes, and this change exceeds a predetermined range. Therefore, the second detection component 73 can sensitively detect whether the aerosol generating matrix 20 has been pulled out of the loading cavity 111, facilitating subsequent control of the aerosol generating device 1000 to automatically stop heating and improving the intelligence level of the aerosol generating device 1000.

[0044] Please refer to Figures 1 to 3In some embodiments, the heating element 30 has a first end 313 and a second end 315 opposite each other in the length direction Z, and the bracket 10 includes a first bracket 13 and a second bracket 15. The first bracket 13 corresponds to the first end 313 of the heating element 30, and an inlet 131 is disposed at the end of the first bracket 13 away from the second bracket 15. The second bracket 15 is connected to the first bracket 13 to form a receiving cavity 11, and the second bracket 15 corresponds to the second end 315 of the heating element 30, and an outlet 1511 is disposed at the end of the second bracket 15 away from the first bracket 13. When the detection component 70 includes a first detection component 71, the first detection component 71 is sleeved on the outer side wall of the first bracket 13; when the detection component 70 includes a second detection component 73, the second detection component 73 is sleeved on the outer side wall of the second bracket 15.

[0045] Specifically, the length direction Z of the heating structure 100 is the same as that of the aerosol generating device 1000. In the length direction Z, the heating element has a first end 313 corresponding to the inlet 131 and a second end 315 corresponding to the outlet 1511, with the first end 313 and the second end 315 facing each other. The first bracket 13 is the structure in the bracket 10 corresponding to the first end 313 of the heating component 30, with the inlet 131 located at the end of the first bracket 13 away from the heating component 30. The second bracket 15 is the structure in the bracket 10 corresponding to the second end 315 of the heating component 30, with the outlet 1511 located at the end of the second bracket 15 away from the heating component 30. The first bracket 13 and the second bracket 15 cooperate to install and support the heating component 30 and the detection component 70, etc., and together they form the receiving cavity 11. The second bracket 15 and the first bracket 13 are opposite each other in the length direction Z and are connected to each other. The connection between the second bracket 15 and the first bracket 13 can be either detachable or non-detachable.

[0046] When the detection assembly 70 includes a first detection assembly 71, the first detection assembly 71 is sleeved on the outer side of the side wall of the first support 13 and arranged around the plug area 1111 in the loading cavity 111 to detect whether the aerosol generating matrix 20 is inserted into the loading cavity 111. When the detection assembly 70 includes a second detection assembly 73, the second detection assembly 73 is sleeved on the outer side of the side wall of the second support 15 and arranged around the mouthpiece area 1113 in the loading cavity 111 to detect whether the aerosol generating matrix 20 is pulled out of the loading cavity 111. It can be understood that when the detection assembly 70 includes both the first detection assembly 71 and the second detection assembly 73, with the first detection assembly 71 sleeved on the outer side of the side wall of the first support 13 and the second detection assembly 73 sleeved on the outer side of the side wall of the second support 15, the detection assembly 70 can simultaneously detect whether the aerosol generating matrix 20 is inserted into the loading cavity 111 and whether the aerosol generating matrix 20 is pulled out of the loading cavity 111.

[0047] In summary, the bracket 10 includes a first bracket 13 and a second bracket 15, with the first detection component 71 fitted onto the first bracket 13 and / or the second detection component 73 fitted onto the second bracket 15. This allows for more flexible installation of the detection component 70 and the bracket 10. Since the areas of the first mounting area 133 and the second mounting area 155 are limited, the detection areas of the first detection component 71 and the second detection component 73 can be adjusted by adjusting the relationship between the first bracket 13 and the second bracket 15, without changing the relative position of the detection component 70 and the bracket 10. This makes the detection of the insertion / removal status of the aerosol generating matrix 20 by the heating component 30 more flexible and adjustable.

[0048] Please refer to Figure 3 In some embodiments, the first detection element 731 includes a first body portion 7311 and a first detection portion 7313. The first body portion 7311 includes a first side facing the second detection element 733, and the first detection portion 7313 is connected to the first body portion 7311 and located on the first side. The second detection element 733 includes a second detection portion 7333, and the second body portion 7331 includes a second side facing the first detection element 731. The second detection portion 7333 is connected to the second body portion 7331 and located on the second side. A plurality of microcapacitors are formed by at least one of the following: between the first detection portion 7313 and the second detection portion 7333, between the first detection portion 7313 and the second body portion 7331, and between the second detection portion 7333 and the first body portion 7311.

[0049] Specifically, please refer to Figures 4 to 6 The first body portion 7311 is the main body of the first detection element 731, and can be used to form a microcapacitor. The first detection portion 7313 is the part of the first detection element 731 used to form the microcapacitor. In the length direction Z, the first body portion 7311 includes a first side facing the second detection element 733, and the first detection portion 7313 is located on the first side of the first body portion 7311 and connected to it. The first body portion 7311 and the first detection portion 7313 can be an integral structure or separate structures. When the first body portion 7311 and the first detection portion 7313 are an integral structure, the structure of the first detection assembly 71 is simple, and the manufacturing process is simple. When the first body portion 7311 and the first detection portion 7313 are separate structures, they can be detachably connected or non-detachably connected, providing greater flexibility in their connection method.

[0050] Please continue reading. Figures 4 to 6The second body portion 7331 is the main body of the second detection element 733, and can be used to form a microcapacitor. The second detection portion 7333 is the part of the second detection element 733 used to form the microcapacitor. In the length direction Z, the second body portion 7331 includes a second side facing the first detection element 731, and the second detection portion 7333 is located on the second side of the second body portion 7331 and connected to it. The first side of the first body portion 7311 and the second side of the second body portion 7331 are opposite each other in the length direction Z. The second body portion 7331 and the second detection portion 7333 can be an integral structure or separate structures. When the second body portion 7331 and the second detection portion 7333 are an integral structure, the structure of the second detection assembly 73 is simple, and the manufacturing process is simple. When the second body portion 7331 and the second detection portion 7333 are separate structures, the second body portion 7331 and the second detection portion 7333 can be detachably connected or non-detachably connected, in which case the connection method is more flexible.

[0051] At this point, along the length direction Z, the structures with opposing planes that can cooperate with each other are: the first detection unit 7313 and the second detection unit 7333, the first detection unit 7313 and the second body unit 7331, and the second detection unit 7333 and the first body unit 7311. Therefore, the two opposing planes of the first detection unit 7313 and the second detection unit 7333 are equivalent to two plates, and these two planes, when spaced apart, can form a microcapacitor; similarly, the two opposing planes of the first detection unit 7313 and the second body unit 7331 are equivalent to two plates, and these two planes, when spaced apart, can also form a microcapacitor; and similarly, the two opposing planes of the first detection unit 7313 and the second body unit 7331 are equivalent to two plates, and these two planes, when spaced apart, can also form a microcapacitor. At this time, the plurality of microcapacitors at least partially include: a microcapacitor formed by the plane of the first detection unit 7313 facing the plane of the second detection unit 7333 and the plane of the second detection unit 7333 facing the first detection unit 7313, a microcapacitor formed by the plane of the first detection unit 7313 facing the plane of the second body unit 7331 and the plane of the second body unit 7331 facing the first detection unit 7313, and a microcapacitor formed by the plane of the first body unit 7311 facing the plane of the second detection unit 7333 and the plane of the second detection unit 7333 facing the first body unit 7311.

[0052] In summary, the first detection element 731 and the second detection element 733, which are spaced apart from each other in the Z-direction of length, can form multiple microcapacitors through the mutual cooperation of the first detection part 7313 and the second detection part 7333, the first detection part 7313 and the second body part 7331, and the second detection part 7333 and the first body part 7311. At this time, the change in equivalent capacitance of the detection component 70 (first detection component 71 and second detection component 73) when the dielectric constant changes is large, the detection sensitivity of the detection component 70 is good, and the detection component 70 can accurately detect the insertion and removal state of the aerosol generating matrix 20 in the loading cavity 111.

[0053] Please refer to Figures 3 to 6 In some embodiments, the first body portion 7311 includes a first end face 73111 facing the second detection element 733, the first end face 73111 being located on a first side, and the first detection portion 7313 consisting of a plurality of first protrusions 73131 spaced apart on the first end face 73111, with a first groove 73133 formed between adjacent first protrusions 73131. The second body portion 7331 includes a second end face 73311 facing the first detection element 731, the second end face 73311 being located on a second side, and the second detection portion 7333 consisting of a plurality of second protrusions 73331 spaced apart on the second end face 73311, with a second groove 73333 formed between adjacent second protrusions 73331. The first protrusion 73131 extends at least partially into the second groove 73333. The outer surfaces of the first protrusion 73131 and the inner surfaces of the second groove 73333 are spaced apart and opposite to each other, forming a microcapacitor with each outer surface of the first protrusion 73131 and the corresponding inner surface of the second groove 73333. The second protrusion 73331 also extends at least partially into the first groove 73133. The outer surfaces of the second protrusion 73331 and the inner surfaces of the first groove 73133 are spaced apart and opposite to each other, forming a microcapacitor with each outer surface of the second protrusion 73331 and the corresponding inner surface of the first groove 73133.

[0054] Specifically, the surface of the first body portion 7311 facing the second detection element 733 is the first end face 73111, which is located on the first side of the first body portion 7311. The first protrusion 73131 is a structure used to form the first detection portion 7313. On the first end face 73111, the first protrusions 73131 protrude from the first end face 73111 and are spaced apart from each other. The groove formed between any two adjacent first protrusions 73131 is the first groove 73133. It can be understood that the bottom of the first groove 73133 is at least a part of the first end face 73111. The shape and size of any two first protrusions 73131 are the same, and the shape and size of any two first grooves 73133 are also the same. This ensures that the changes in the multiple microcapacitors formed by the first detection portion 7313 are uniform, and the output first electrical signal (second electrical signal) is relatively regular.

[0055] The surface of the second body portion 7331 facing the first detection element 731 is the second end face 73311, located on the second side of the second body portion 7331. The second protrusions 73331 are structures used to form the second detection portion 7333. On the second end face 73311, the second protrusions 73331 protrude from the second end face 73311 and are spaced apart from each other. The groove formed between any two adjacent second protrusions 73331 is the second groove 73333. It can be understood that the bottom of the second groove 73333 is at least a portion of the second end face 73311. The shape and size of any two second protrusions 73331 are identical, and the shape and size of any two second grooves 73333 are also identical. This ensures that the changes in the multiple microcapacitors formed by the second detection portion 7333 are uniform, and the output first electrical signal (second electrical signal) is relatively regular.

[0056] Along the length direction Z, the first detection element 731 and the second detection element 733 cooperate with each other. Specifically, at least a portion of the first protrusion 73131 of the first detection element 731 extends into the second groove 73333 of the second detection element 733, and at least a portion of the second protrusion 73331 of the second detection element 733 extends into the first groove 73133 of the first detection element 731. At this time, each outer surface of the first protrusion 73131 and each inner surface of the second groove 73333 are spaced apart and opposite to each other, and each outer surface of the second protrusion 73331 and each inner surface of the first groove 73133 are spaced apart and opposite to each other. Therefore, each outer surface of the first protrusion 73131 and the corresponding inner surface of the second groove 73333 form multiple microcapacitors, and each outer surface of the second protrusion 73331 and the corresponding inner surface of the first groove 73133 also form multiple microcapacitors.

[0057] In summary, the first protrusion 73131 and the first groove 73133 of the first detection element 731 respectively cooperate with the second groove 73333 and the second protrusion 73331 of the second detection element 733. The outer surfaces of any two cooperating protrusions and the inner surfaces of the grooves are opposite to each other, forming a microcapacitor. At this time, the number of microcapacitors is relatively large, and the effective area of ​​the corresponding electrode plate is relatively large. Therefore, the capacitance change of the detection component 70 (first detection component 71 and second detection component 73) is relatively large when the dielectric constant changes. The detection sensitivity of the detection component 70 is good, and the detection component 70 can accurately detect the insertion and removal state of the aerosol generating matrix 20 in the loading cavity 111.

[0058] Please refer to Figure 3 and Figure 4 In some embodiments, the longitudinal section of the first protrusion 73131 and the longitudinal section of the second protrusion 73331 are both rectangular, and the longitudinal section is the section cut by the circumferential surface of the first detection element 731.

[0059] Specifically, in the above embodiment, the cross-sections of the first protrusion 73131 and the second protrusion 73331 intercepted by the circumferential surface of the first detection element 731 are defined as longitudinal sections. In this case, the longitudinal section of the first protrusion 73131 is rectangular, and the longitudinal section of the second protrusion 73331 is also rectangular. The dimensions of the longitudinal section of the first protrusion 73131 and the dimensions of the cross-section of the second protrusion 73331 can be the same or different.

[0060] Using a first protrusion 73131 and a first groove 73133, and a corresponding second protrusion 73331 and a second groove 73333 as the smallest unit for forming a microcapacitor in the detection component 70, with both the longitudinal section of the first protrusion 73131 and the longitudinal section of the second protrusion 73331 being rectangular, this smallest unit contains four mutually spaced and opposite planes: plane A1 on one side of the outer surface of the second protrusion 73331 and plane B1 on one side of the inner surface of the first groove 73133; plane A2 at the top of the outer surface of the second protrusion 73331 and plane B2 at the bottom of the inner surface of the first groove 73133; plane A3 on the other side of the outer surface of the second protrusion 73331 and plane B3 on the other side of the inner surface of the first groove 73133; and plane A4 at the bottom of the inner surface of the second groove 73333 and plane B4 at the top of the outer surface of the first protrusion 73131. At this time, the area of ​​the opposing planes between the first detection element 731 and the second detection element 733 is relatively large. Therefore, the capacitance change of the detection assembly 70 (first detection assembly 71 and second detection assembly 73) is relatively large when the dielectric constant changes, resulting in good detection sensitivity. The detection assembly 70 can accurately detect the insertion / removal state of the aerosol generating matrix 20 in the loading cavity 111. Simultaneously, the processing of the first protrusion 73131 and the second protrusion is simpler at this time, as is the processing of the detection assembly 70.

[0061] Please refer to Figure 3 and Figure 5 In some embodiments, the longitudinal section of the first protrusion 73131 and the longitudinal section of the second protrusion 73331 are both trapezoidal, and the longitudinal section is the section cut by the circumferential surface of the first detection element 731.

[0062] Specifically, when the longitudinal section of the first protrusion 73131 is trapezoidal and the longitudinal section of the second protrusion 73331 is trapezoidal, the dimensions of the longitudinal section of the first protrusion 73131 and the dimensions of the cross section of the second protrusion 73331 can be the same or different. Using a first protrusion 73131 and a first groove 73133, and a corresponding second protrusion 73331 and a second groove 73333 as the smallest unit for forming a microcapacitor in the detection component 70, when the longitudinal section of the first protrusion 73131 and the longitudinal section of the second protrusion 73331 are both trapezoidal, there are four mutually spaced and opposite planes in this smallest unit, namely, plane C1 on one side of the outer side of the second protrusion 73331 and plane D1 on one side of the inner side of the first groove 73133, plane C2 on the top of the outer side of the second protrusion 73331 and plane D2 on the bottom of the inner side of the first groove 73133, plane C3 on the other side of the outer side of the second protrusion 73331 and plane D3 on the other side of the inner side of the first groove 73133, and plane C4 on the bottom of the inner side of the second groove 73333 and plane D4 on the top of the outer side of the first protrusion 73131. At this time, the area of ​​the planes facing each other between the first detection element 731 and the second detection element 733 is relatively large. At this time, the capacitance change of the detection component 70 (first detection component 71 and second detection component 73) is relatively large when the dielectric constant changes, the detection sensitivity of the detection component 70 is good, and the detection component 70 can accurately detect the insertion and removal status of the aerosol generating matrix 20 in the loading cavity 111.

[0063] Please refer to Figure 3 and Figure 6 In some embodiments, the longitudinal section of the first protrusion 73131 and the longitudinal section of the second protrusion 73331 are both triangular, and the longitudinal section is the section cut by the circumferential surface of the first detection element 731.

[0064] Specifically, when both the first protrusion 73131 and the second protrusion 73331 have a triangular longitudinal section, the dimensions of the longitudinal section of the first protrusion 73131 and the cross-section of the second protrusion 73331 can be the same or different. Using a first protrusion 73131, a first groove 73133, and a corresponding second protrusion 73331 and a second groove 73333 as the smallest unit for forming a microcapacitor in the detection component 70, when both the longitudinal sections of the first protrusion 73131 and the second protrusion 73331 are triangular, this smallest unit contains two mutually spaced and opposite planes: plane E1 on one side of the outer surface of the second protrusion 73331 and plane F1 on one side of the inner surface of the first groove 73133; and plane E2 on the other side of the outer surface of the second protrusion 73331 and plane F2 on the other side of the inner surface of the first groove 73133. At this time, the area of ​​the opposing planes between the first detection element 731 and the second detection element 733 is moderate, which is suitable for application scenarios with low detection sensitivity requirements. At this time, when the dielectric constant corresponding to the detection components 70 (first detection component 71 and second detection component 73) changes, the capacitance changes, and the detection components 70 can detect the insertion and removal status of the aerosol generation matrix 20 in the loading cavity 111 more accurately.

[0065] Please refer to Figures 3 to 6 In some embodiments, the distance between each outer side of the second protrusion 73331 and each inner side of the first groove 73133 is greater than or equal to 0.18 mm and less than or equal to 0.22 mm.

[0066] Specifically, the spacing between the outer surfaces of the second protrusion 73331 and the inner surfaces of the first groove 73133 determines the spacing between the first detection element 731 and the second detection element 733, thereby affecting the electrode spacing parameter of each microcapacitor, and consequently affecting the capacitance value of the equivalent capacitor. The spacing between the outer surfaces of the second protrusion 73331 and the inner surfaces of the first groove 73133 can be, but is not limited to, any one or any two of 0.18mm, 0.184mm, 0.188mm, 0.192mm, 0.196mm, 0.20mm, 0.204mm, 0.208mm, 0.212mm, and 0.22mm. If the distance between the outer surfaces of the second protrusion 73331 and the inner surfaces of the first groove 73133 is less than 0.18 mm, the distance between the first detection element 731 and the second detection element 733 is too small. In this case, the capacitance value of the equivalent capacitor is too large, and the detection sensitivity of the detection component 70 (first detection component 71 and second detection component 73) is too high. Even a small disturbance can cause a change in the first electrical signal (second electrical signal), resulting in a high probability of false detection, and the heating component 30 cannot be engineered. If the distance between the outer surfaces of the second protrusion 73331 and the inner surfaces of the first groove 73133 is greater than 0.22 mm, the distance between the first detection element 731 and the second detection element 733 is too large. In this case, the capacitance value of the equivalent capacitor is too small, and the detection sensitivity of the detection component 70 (first detection component 71 and second detection component 73) is too low, making it impossible to accurately detect the insertion and removal status of the aerosol generating matrix 20. Therefore, the spacing between each outer side of the second protrusion 73331 and each inner side of the first groove 73133 is within the range mentioned above. The detection sensitivity of the detection component 70 (first detection component 71 and second detection component 73) is appropriate, and the detection component 70 can sensitively and accurately detect the insertion and removal status of the aerosol generating matrix 20 in the loading cavity 111.

[0067] Please refer to Figures 1 to 3 In some embodiments, the bracket 10 includes a protrusion, and the first body portion 7311 and / or the second body portion 7331 are provided with a notch, which is configured to engage with the protrusion.

[0068] Specifically, in the above embodiment, the protrusion protrudes from the surface of the bracket 10 to form a raised structure. When the first detection component 71 is disposed in the first mounting area 133, the surface of the bracket 10 is provided with a first protrusion 171, and the first body portion 7311 of the first detection component 71 is provided with a first notch 73113. At this time, the first notch 73113 can engage with the first protrusion 171, so that the first detection component 71 and the bracket 10 can be stably connected and cooperate with each other. The structural stability of the heating component 30 is good, and the first detection component 71 is not easy to move. Therefore, it is possible to more accurately detect whether the aerosol generating matrix 20 is inserted into the loading cavity 111.

[0069] With the second detection component 73 positioned in the second mounting area 155, the surface of the bracket 10 is provided with a second protrusion 173, and the second body portion 7331 of the second detection component 73 is provided with a second notch 73313. In this case, the second notch 73313 can engage with the second protrusion 173, allowing the second detection component 73 and the bracket 10 to be stably connected and cooperate with each other. This results in better structural stability of the heating component 30, and the second detection component 73 is less prone to displacement. Therefore, it is possible to more accurately detect whether the aerosol generating matrix 20 has been removed from the loading cavity 111.

[0070] With the first detection component 71 disposed in the first mounting area 133 and the second detection component 73 disposed in the second mounting area 155, the surface of the bracket 10 is provided with a first protrusion 171 and a second protrusion 173. At this time, the first body portion 7311 of the first detection component 71 is provided with a first notch 73113, and the second body portion 7331 of the second detection component 73 is provided with a second notch 73313. The first notch 73113 can engage with the first protrusion 171, allowing the first detection component 71 and the bracket 10 to be stably connected and cooperate; and the second notch 73313 can engage with the second protrusion 173, allowing the second detection component 73 and the bracket 10 to be stably connected and cooperate. Therefore, the heating component 30 has better structural stability, and the first detection component 71 and the second detection component 73 are less prone to displacement, thus enabling more accurate detection of the insertion and removal status of the aerosol generating matrix 20 in the loading cavity 111.

[0071] Please refer to Figures 1 to 3 In some embodiments, the heating structure 100 further includes an end heat insulation ring 51. The end heat insulation ring 51 is sandwiched between the heating component 30 and the support 10 along the length direction Z of the heating component 30. The end heat insulation ring 51 is used to prevent the heat generated by the heating component 30 from being transferred to the outside of the atomization cavity 311 along the length direction Z, and to seal the gap between the heating component 30 and the support 10.

[0072] Specifically, the end heat insulation ring 51 is a structure used to prevent the heat generated by the heating element 30 from being transmitted along the length direction Z of the aerosol generating device 1000. The end heat insulation ring 51 can be made of at least one of the following materials: rubber, silicone, or heat-resistant plastic. In the length direction Z of the heating element 30, the end heat insulation ring 51 is sandwiched between the heating element 30 and the support 10. The end heat insulation ring 51 and the heating element 30 can be detachably or non-detachably connected. Similarly, the end heat insulation ring 51 and the support 10 can also be detachably or non-detachably connected.

[0073] At this time, as the heat generated by the heating element 30 is transferred to the outside of the Z-atomization chamber 311 along its length, the end heat insulation ring 51 can isolate at least part of the heat, allowing more heat to act on the aerosol generating matrix 20. Furthermore, the end heat insulation ring 51 can seal the gap between the heating element 30 and the support 10, preventing the generated aerosol from leaking out of the gap to the outside of the heating element 30. Therefore, the end heat insulation ring 51 reduces the energy loss of the heating element 30, improves the energy utilization rate of the heating element 30, and prevents aerosol leakage to the outside of the heating element 30, preventing leaked aerosol from affecting the normal operation of other components and extending the service life of the aerosol generating device 1000 used in the heating structure 100.

[0074] In some examples, an end heat insulation ring 51 is sandwiched between the second end 315 and the bracket 10. In this case, at least a portion of the bracket 10, the end heat insulation ring 51, and the heating element 30 (the second end 315) are arranged sequentially in the length direction Z. The end heat insulation ring 51 is used to block the heat generated by the heating element 30 from being transferred to the outside of the atomizing chamber 311 through the second end 315, thereby reducing energy loss and improving the energy utilization rate of the heating element 30.

[0075] In other examples, an end heat insulation ring 51 is sandwiched between the first end 313 and the support 10. In this case, at least a portion of the support 10, the end heat insulation ring 51, and the heating element 30 (first end 313) are arranged sequentially along the length direction Z. The end heat insulation ring 51 is used to prevent the heat generated by the heating element 30 from being transferred to the outside of the atomizing chamber 311 through the first end 313. At this time, since air flows into the inlet 131 and aerosol with a certain temperature flows out of the outlet 1511, the temperature of the outlet 1511 is higher than that of the inlet 131, thus improving the energy utilization rate of the heating element 30.

[0076] In some other examples, end heat insulation rings 51 are sandwiched between the second end 315 and the support 10, and between the first end 313 and the support 10. In this case, along the length direction Z, the support 10 (one end), the (first) end heat insulation ring 51, the heating element 30, the (second) end heat insulation ring 51, and the support 10 (the other end) are arranged sequentially. The end heat insulation ring 51 is used to block the heat generated by the heating element 30 from being transferred to the outside of the atomizing chamber 311 through the second end 315 and the first end 313. In this case, compared with the case where the end heat insulation ring 51 is only set at one end of the heating element 30, the energy utilization rate of the heating element 30 is the highest when the end heat insulation ring 51 is set at both ends of the heating element 30. At this time, more aerosol can be generated and the generated aerosol has a better taste.

[0077] Please refer to Figures 1 to 3In some embodiments, the heating structure 100 further includes a heat shield 55. The heat shield 55 is fitted onto the outer side of the side wall of the support 10 and is used to prevent heat from being transferred along the outer side of the side wall of the support 10 in a direction away from the atomizing chamber 311.

[0078] Specifically, the heat insulation cover 55 is a structure used to prevent heat from being transferred along the outer side of the sidewall of the support 10 in a direction away from the atomizing cavity 311. The heat insulation cover 55 is sleeved on the support 10, specifically on the outer sidewall of the support 10. At this time, the heat insulation cover 55 has a large coverage area on the sidewall of the support 10. When the heat generated by the heating element 30 is transferred in the direction X perpendicular to the length direction Z in a direction away from the atomizing cavity 311, the heat insulation cover 55 can prevent the heat from being transferred to the outside of the heating structure 100. Therefore, the heating structure 100 of this application uses the heat insulation cover 55 to block the heat generated by the heating element 30 in a direction away from the atomizing cavity 311, thereby reducing the heat loss of the heating structure 100, improving the energy utilization rate, and generating more aerosol with a better taste.

[0079] Please refer to Figure 7 Secondly, this application provides an aerosol generating apparatus 1000. The aerosol generating apparatus 1000 includes a battery assembly 300 and a heating structure 100 as described in any embodiment, wherein the heating structure 100 is electrically connected to the battery assembly 300.

[0080] Specifically, in the above practical method, it should be noted that the specific structure and properties of the heating structure 100 in this embodiment are exactly the same as those in the above embodiments, and will not be explained again here. The aerosol generating device 1000 is a structure capable of generating aerosols by heating the aerosol generating matrix 20. The battery assembly 300 is used to provide electrical energy to the components in the aerosol generating device 1000 that require electricity (e.g., the heating structure 100), so that the heating structure 100 can heat the atomized aerosol generating matrix 20 to form an aerosol. For example, when the aerosol generating device 1000 is aspirated, the battery assembly 300 supplies power to the heating structure 100; in this case, the heating structure 100 heats the aerosol generating matrix 20 and generates aerosols. When the user does not aspirate the aerosol generating device 1000, the battery assembly 300 stops supplying power to the heating structure 100; in this case, the heating structure 100 does not heat the aerosol generating matrix 20. It should be noted that, in some embodiments, the battery assembly 300 can be a dry cell battery or a rechargeable battery. Rechargeable batteries include, but are not limited to, lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0081] In the aerosol generating apparatus 1000 of this application, the heating component 30 heats the aerosol generating matrix 20 inserted into the loading cavity 111 to generate aerosol for the user to inhale. A detection component 70 is provided along the insertion path of the aerosol generating matrix 20 into the loading cavity 111. The detection component 70 is arranged around the loading cavity 111. The equivalent capacitance formed by the microcapacitors of the first detection element 731 and the second detection element 733 changes during the insertion of the aerosol generating matrix 20 into the loading cavity 111, and outputs an electrical signal characterizing the capacitance value of the equivalent capacitance. This electrical signal can be used to determine the insertion / removal state of the aerosol generating matrix 20 relative to the loading cavity 111. The microcapacitors in the detection component 70 result in high detection sensitivity, rapid detection, and accurate detection results. Therefore, the configuration of the detection component 70 enables the aerosol generating apparatus 1000 to accurately detect the insertion / removal state and to decide whether to start or stop heating based on the determination of the insertion / removal state.

[0082] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
