Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to a heating system and atomization equipment. Background Technology

[0002] Currently, heated non-combustible atomizing devices are used to heat aerosol generating rods inserted into a heating chamber, causing the atomizing matrix inside the aerosol generating rod to atomize and generate aerosols. Common aerosol generating rods are divided into several different types based on their internal structure. For example, one type of aerosol generating rod stores the atomizing matrix at the bottom (Type 1), while another type has a sponge structure at the bottom (Type 2). The optimal heating methods (e.g., heating temperature, heating time) differ between different types of aerosol generating rods. If the heating method is incompatible with the type of aerosol generating rod, it will affect the atomization effect of the atomizing matrix. However, existing atomizing devices can only identify whether the aerosol generating rod is properly assembled, making it difficult to effectively identify the type of aerosol generating rod. Therefore, they can only use the same heating method, which is not compatible with different types of aerosol generating rods, resulting in affected atomization effects. Utility Model Content

[0039] 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.

[0040] 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.

[0041] An aerosol generator is a special atomizing product containing an atomizing matrix. It is inserted into a matching heated non-combustible atomizing device, where a heating element heats the generator, causing the atomizing matrix inside to atomize and generate an aerosol. As the user draws air from the generator, the aerosol is carried to the suction end. Different types of aerosol generators have varying internal structures, and the storage location of the atomizing matrix also differs. For example, some have it at the bottom (the end inserted into the heating chamber), while others maintain a certain distance from the bottom (with a sponge at the bottom).

[0042] The heating system provided in this application employs a heating component with a detection component inside the heating chamber. The detection component can emit light along a preset path within the heating chamber and detect the light parameters at a target position along the preset path. When the aerosol generating rod is inserted into the heating chamber and affects the light at the target position, the different internal structures of the aerosol generating rod have different degrees of influence on the light. The controller can determine the specific type of the aerosol generating rod based on the light parameters detected by the detection component, thereby controlling the working state of the heating component to adapt the heating method to the specific type of the aerosol generating rod and improve the heating atomization efficiency.

[0043] The following describes some embodiments of the heating system and atomizing device provided in this application with reference to the accompanying drawings.

[0044] The first aspect of this application provides a heating system 100, such as... Figure 1 , Figure 2 , Figure 3 As shown, the heating system 100 includes a heating assembly 1, a detection assembly 2, and a controller 3. The heating assembly 1 has a heating chamber 131, one end of which is an insertion port 1311 in a first direction. The heating chamber 131 is used to accommodate the aerosol generating rod and to heat the aerosol generating rod inserted into the heating chamber 131, such as... Figure 4 and Figure 5 In the example, heating component 1 is communicatively connected to controller 3 to operate according to control commands from controller 3. Controller 3 can control heating component 1 to adopt different heating methods. Detection component 2 is disposed in heating cavity 131. Detection component 2 can emit light along a preset path within heating cavity 131 and detect light parameters (including but not limited to light intensity, luminous flux, and illuminance) at a target position along the preset path. Detection component 2 is communicatively connected to controller 3 and can send the detected light parameters to controller 3. Figure 4 and Figure 5In the example, when the aerosol generating rod 500 is inserted into the heating chamber 131, the aerosol generating rod 500 will pass through the preset path and affect the light on the preset path. The controller 3 identifies the type of the corresponding aerosol generating rod 500 according to the light parameters, and then controls the heating component 1 to heat in a heating method that is compatible with the aerosol generating rod 500.

[0045] It is understandable that different aerosol generating rods have different internal structures, and these structures also differ in their light transmittance. For example, the atomizing matrix stored in aerosol generating rods is usually a tobacco product, which has poor light transmittance and blocks most of the light. In contrast, the sponge in an aerosol generating rod has a porous structure that allows for relatively higher light transmittance, enabling some light to pass through. Therefore, when the measuring component is set to emit light along a preset path and detect the light parameters at a fixed target position, different types of aerosol generating rods inserted into the heating chamber will have different effects on the light along the preset path, resulting in different light parameters detected at the target position.

[0046] The heating system 100 in this embodiment has been improved and optimized in structure based on the above principle. A detection component 2 that can emit light along a preset path is set in the heating chamber 131. When the aerosol generating rod 500 is inserted into the heating chamber 131, the controller 3 can identify the type of aerosol generating rod 500 based on the different magnitudes of the light parameters detected by the detection component 2 at the target position. Then, the controller 1 can be controlled to adopt a heating method that is compatible with the aerosol generating rod 500, which can effectively improve the atomization effect and improve the user experience.

[0047] It should be noted that the heating component 1 can operate in different heating methods. For example, the heating temperature and heating time can be adjusted according to the type of aerosol generating rod, and local heating can be applied to different areas to reduce energy consumption and improve the heating and atomization efficiency of the atomizing matrix. In addition, in practical applications, the controller can be specifically set in the heating component or the detection component, or it can be set in other locations in the atomization device, such as the electronic control board of the power supply component.

[0048] In further embodiments of this application, such as Figures 1 to 5In the example, the heating chamber 131 of the heating assembly 1 has a first heating section 1312 at the end away from the insertion port 1311. The first heating section 1312 is used to accommodate the bottom end of the aerosol generating rod 500. That is, when the aerosol generating rod 500 is inserted into the heating chamber 131 and assembled in place, the bottom end of the aerosol generating rod 500 is located in the first heating section 1312 of the heating chamber 131. The detection component 2 specifically includes a light source emitter 21 and a light intensity detector 22. The light source emitter 21 and the light intensity detector 22 are spaced apart in the heating cavity 131. The path between the light source emitter 21 and the light intensity detector 22 is the preset path. The position of the light intensity detector 22 is the target position on the preset path. The light emitted by the light source emitter 21 can propagate along the preset path to the target position. The light intensity detector 22 is used to detect the light intensity at the target position. The preset path passes through the first heating section 1312 so that when the bottom end of the aerosol generating rod 500 is inserted into the first heating section 1312, it can affect the light on the preset path. The light intensity detected by the cover plate light intensity detector 22 at the target position allows the controller 3 to identify the type of the corresponding aerosol generating rod 500 based on the change in light intensity at the target position.

[0049] It is understandable that the structure of the bottom of commonly used aerosol generating rods varies depending on the type; for example, some have an atomizing matrix stored at the bottom (such as...). Figure 4 (as shown in the example), some have sponge at the bottom (such as...) Figure 5 (Example in the example) In this embodiment, the arrangement of the light intensity emitter and light intensity detector 22 is such that the preset path passes through the first heating section 1312 of the heating cavity 131, which corresponds to the bottom structure of the aerosol generating rod 500, so that the controller 3 can identify the type of the bottom structure of the aerosol generating rod 500 according to the change in light intensity.

[0050] It should be noted that the light source emitter 21 and the light intensity detector 22 can be located in the first heating section 1312 or outside the first heating section 1312, as long as the preset path formed between them passes through the first heating section 1312. The controller 3 can preset a type recognition model for the aerosol generating rod, which can perform calculations and recognition based on the input light parameters.

[0051] In further embodiments of this application, such as Figures 3 to 5 In the example, the light source emitter 21 and light intensity detector 22 of the detection component 2 are respectively located at the bottom of the heating cavity 131 and the other is located on the inner wall of the heating cavity 131 at a position corresponding to the first heating section 1312. Figure 4In the example shown, the light source emitter 21 is located at the bottom of the heating cavity 131, emitting light upwards. Correspondingly, the light intensity detector 22 is located on the inner wall of the heating cavity 131, within the first heating section 1312. The angle α between the line connecting the light source emitter 21 and the light intensity detector 22 and the horizontal plane is not less than a first preset angle, ensuring that the light intensity detector 22 is within the light-emitting range of the light source emitter 21. The preset path is the line connecting the light source emitter 21 and the light intensity detector 22, inclined to the vertical plane, with the light propagating from the bottom of the heating cavity 131 towards the inner wall. This arrangement fully utilizes the space at the bottom of the heating cavity 131, allowing for the placement of a light source emitter 21 with a larger light-emitting area, thereby increasing the light-emitting range. The first preset angle can be set according to the specific structural and dimensional design.

[0052] Of course, in practical applications, such as Figure 6 In the example, the light source emitter 21 can also be placed on the inner wall of the heating cavity 131, while the light intensity detector 22 is placed at the bottom of the heating cavity 131. In this case, the preset path is still an inclined line inclined to the vertical plane, but the light propagation direction is from the inner wall of the heating cavity 131 to the bottom.

[0053] Furthermore, such as Figure 7 In the example, the detection component 2 has multiple light intensity detectors 22, all of which are located on the inner wall of the heating cavity 131 and spaced circumferentially. The light source emitter 21 is correspondingly located at the bottom of the heating cavity 131, and the multiple light intensity detectors 22 are all within the illumination range of the light source emitter 21, realizing a one-to-many light emission detection mode to form multiple preset paths with different propagation directions, and each preset path passes through the first heating section 1312 of the heating cavity 131. When the bottom of the aerosol generating rod 500 is inserted into the first heating section 1312, the detection data of the multiple light intensity detectors 22 changes. The controller 3 makes a comprehensive judgment based on the data of the multiple light intensity detectors 22 to identify the type of the corresponding aerosol generating rod 500.

[0054] The controller 3 can perform comprehensive calculations on the received multiple detection data according to a preset model or program, such as making a judgment based on the average value of multiple detection data, or using the maximum or minimum value among multiple detection data as the basis for judgment.

[0055] The above method can increase the number of samples for type recognition by controller 3, thereby avoiding the phenomenon that anomalies in a single sample will affect the accuracy of the recognition results. This is conducive to further improving the recognition accuracy and enabling more precise recognition and heating operations for aerosol generating rod 500.

[0056] Of course, in practical applications, multiple light intensity detectors can also be set at the bottom of the heating cavity 131 and arranged in an array (e.g., a matrix or a ring array), while the light source emitter 21 is correspondingly set on the inner wall of the heating cavity 131. The light emission range of the light source emitter 21 can simultaneously cover multiple light intensity detectors 22, which can also realize a one-to-many light emission detection mode and improve recognition accuracy.

[0057] Furthermore, in another specific example, the number of light source emitters 21 in the detection component 2 can be set to multiple. These multiple light source emitters 21 can be arranged circumferentially at intervals on the inner wall of the heating cavity 131, while the light intensity detector 22 is correspondingly arranged at the bottom of the heating cavity 131. Multiple light source emitters 21 emit light from different angles to the light intensity detector 22, achieving a many-to-one light emission detection mode and forming multiple preset paths with propagation directions, thereby further increasing the illumination coverage. All preset paths pass through the first heating section 1312 of the heating cavity 131. When the bottom of the aerosol generating rod 500 is inserted into the first heating section 1312 of the heating cavity 131, the light on multiple preset paths is affected, and the light detection data of the light on multiple preset paths changes. The controller 3 makes a comprehensive judgment based on the multiple detection data to identify the type of the corresponding aerosol generating rod 500.

[0058] The above method can also increase the number of samples for type recognition by controller 3, thereby avoiding the phenomenon that anomalies in a single sample will affect the accuracy of the recognition results. This is conducive to further improving the recognition accuracy and enabling more precise recognition and heating operations for aerosol generating rod 500.

[0059] Of course, in practical applications, multiple light source emitters 21 can also be set at the bottom of the heating cavity 131 and arranged in an array (e.g., a matrix or a ring array), while the light intensity detector 22 is set on the inner wall of the heating cavity 131. The multiple light source emitters 21 can simultaneously cover the light intensity detector 22, which can also realize a many-to-one light emission detection mode and improve the recognition accuracy.

[0060] In another specific example, the detection component 2 can also be equipped with multiple light source emitters 21 and multiple light intensity detectors 22 at the same time, thereby forming a many-to-many light emission detection mode, which can further improve the accuracy of detection and recognition.

[0061] In further embodiments of this application, such as Figure 8As shown, the light source emitter 21 and light intensity detector 22 of the detection component 2 are both located on the inner wall of the heating cavity 131 at positions corresponding to the first heating section 1312, and are spaced apart in the circumferential direction; in the circumferential direction, the central angle b corresponding to the light source emitter 21 and the light intensity detector 22 is not less than a second preset angle, such as... Figure 9 The example in the text is to position the light intensity detector within the illumination range of the light source emitter 21. The second preset angle can be set according to the specific structure and size design. When the bottom of the aerosol generating rod 500 is inserted into the first heating section 1312 of the heating cavity 131, the preset path passes laterally through the first heating section 1312. This embodiment provides another way to set the detection component 2, eliminating the need to set the light source emitter 21 or light intensity detector 22 at the bottom of the heating cavity 131, making it suitable for situations where the space at the bottom of the heating cavity 131 is limited or interferes with other structures at the bottom.

[0062] Furthermore, in a specific example, such as Figure 9 As shown, the detection component 2 has multiple light intensity detectors 22, which, along with the light source emitter 21, are all located on the inner wall of the heating cavity 131 and spaced circumferentially. All light intensity detectors 22 are located within the illumination range of the light source emitter 21, achieving a one-to-many light emission detection mode to form multiple preset paths with different propagation directions. Each preset path passes through the first heating section 1312 of the heating cavity 131. When the bottom of the aerosol generating rod 500 is inserted into the first heating section 1312, the detection data of the multiple light intensity detectors 22 changes. The controller 3 makes a comprehensive judgment based on the data from the multiple light intensity detectors 22 to identify the type of the corresponding aerosol generating rod 500. This method increases the number of samples for type identification by the controller 3, thus avoiding the phenomenon that an abnormality in a single sample affects the accuracy of the identification result. This is beneficial for further improving identification accuracy and for more precise identification and heating operation of the aerosol generating rod 500.

[0063] Furthermore, in another specific example, such as Figure 10In the example, the number of light source emitters 21 in the detection component 2 can be set to multiple. Multiple light source emitters 21 and light intensity detectors 22 can be arranged circumferentially on the inner wall of the heating cavity 131. Multiple light source emitters 21 emit light from different angles to the light intensity detectors 22, achieving a many-to-one light emission detection mode and forming multiple preset paths with propagation directions, further increasing the illumination coverage. All preset paths pass through the first heating section 1312 of the heating cavity 131. When the bottom of the aerosol generating rod 500 is inserted into the first heating section 1312 of the heating cavity 131, the light on multiple preset paths is affected, and the light detection data of the light on multiple preset paths changes. The controller 3 makes a comprehensive judgment based on the multiple detection data to identify the type of the corresponding aerosol generating rod 500. The above method can also increase the number of samples for type recognition by controller 3, thereby avoiding the phenomenon that anomalies in a single sample will affect the accuracy of the recognition results. This is conducive to further improving the recognition accuracy and enabling more precise recognition and heating operations for aerosol generating rod 500.

[0064] In addition, in practical applications, the detection component 2 can also be equipped with multiple light source emitters 21 and multiple light intensity detectors 22 at the same time, thereby forming a many-to-many light emission detection mode, which can further improve the accuracy of detection and recognition.

[0065] Specifically, in a particular example, such as Figure 11 In the example, the light source emitter 21 of the detection component 2 is tilted toward the light intensity detector 22. For example, the light intensity detector 22 is located on the side wall of the heating cavity 131, and the light source emitter 21 is located at the bottom of the heating cavity 131. The light-emitting surface of the light source emitter 21 is tilted toward the side where the light intensity detector 22 is located relative to the vertical plane, so that the light-emitting surface of the light source emitter 21 forms a certain tilt angle with the vertical plane. This makes the light intensity detector 22 located in the area near the middle of the illumination range of the light source emitter 21, with better illumination conditions. When the aerosol generating rod 500 is inserted into the heating cavity 131, the influence on the light is more obvious, making the change in the detection data of the light intensity detector 22 more obvious.

[0066] In another specific example, such as Figures 3 to 8 In the example shown, in detection component 2, the light source emitter 21 specifically adopts an infrared light emitter to emit infrared light rays. Since infrared light is invisible and cannot be seen by the human eye, it can avoid the phenomenon of glare during use, which is beneficial to improving the user experience. The light intensity detector 22 can detect infrared light rays and detect the light intensity.

[0067] Of course, in practical applications, the light source emitter 21 can also be a visible light emitter, such as a light-emitting diode (LED), depending on actual needs.

[0068] In further embodiments of this application, such as Figure 1 , Figure 4 and Figure 12 As shown, in the heating system 100, the heating assembly 1 includes a support sleeve 11, a support base 12, and a heating element 13. The support sleeve 11 has a mounting cavity 111 extending along a first direction, and the heating element 13 is disposed in the mounting cavity 111 along the first direction. An abutment structure 112 is located on the inner wall of the support sleeve 11 near one end, and the abutment structure 112 abuts against one end of the heating element 13. The support base 12 is located at the end of the support sleeve 11 away from the abutment structure 112 and is detachably connected to the support sleeve 11. The end of the support base 12 facing the abutment structure 112 has a base connecting groove 123, which extends into the mounting cavity 111 and abuts against the end of the heating element 13 away from the abutment structure 112. Thus, the base connecting groove 123 and the abutment structure 112 clamp the two ends of the heating element 13 to fix it in place. The heating element 13 has a cylindrical structure to match the shape of the aerosol generating rod 500, and its sidewall has an electrical connection structure for electrical connection with the power supply component when used in an atomizing device. The internal space of the heating element 13 communicates with the internal space of the base connecting groove 123 to form a heating chamber 131. The first heating section 1312 is located in the base connecting groove 123, and correspondingly, the detection component 2 is disposed in the base connecting groove 123.

[0069] It should be noted that in practical applications, both the support sleeve 11 and the support base 12 are made of high-temperature resistant plastic material, such as PEEK (polyetheretherketone), which helps to improve service life and also facilitates processing, molding, and assembly. Figure 4 In the example, both the abutment structure 112 and the base connecting groove 123 adopt an annular structure to be compatible with the heating tube; the contact surface between the base connecting groove 123 and the heating tube 13 can be provided with a sealing structure 16, such as a silicone structure, to seal and buffer the heating tube 13.

[0070] Furthermore, in a specific example, such as Figure 4 In the example, a first mounting hole 1231 is provided on the inner sidewall of the base connecting groove 123, and a second mounting hole 1232 is provided on the bottom wall of the base connecting groove 123; of the light source emitter 21 and the light intensity detector 22 of the detection assembly 2, one is installed in the first mounting hole 1231 and the other is installed in the second mounting hole 1232, for example... Figure 4In the example, the light intensity detector 22 is installed in the first mounting hole 1231, and the light source emitter 21 is located in the second mounting hole 1232, so as to facilitate the assembly and fixation of the light source emitter 21 and the light intensity detector 22.

[0071] In another specific example, such as Figure 8 In the example, a plurality of first mounting slots are provided on the inner sidewall of the base connecting slot 123, and the plurality of first mounting slots are spaced apart along the circumference. The light source emitter 21 and the light intensity detector 22 of the detection component 2 are respectively installed in different first mounting slots to assemble and fix the light source emitter 21 and the light intensity detector 22.

[0072] In further embodiments of this application, such as Figures 4 to 8 In the example, the base connecting groove 123 of the support base 12 has multiple base protrusions 1233. The base protrusions 1233 are located at the connection between the bottom wall and the inner side wall of the base connecting groove 123, and the multiple base protrusions 1233 are spaced apart circumferentially. When the aerosol generating rod 500 is inserted into the heating chamber 131, the bottom end of the aerosol generating rod 500 abuts against the top surface of the multiple base protrusions 1233, so that a certain gap is maintained between the bottom surface of the aerosol generating rod 500 and the bottom wall of the base connecting groove 123, so as to avoid contact with the light source emitter 21 or light intensity detector 22 located on the bottom wall, and at the same time, a certain airflow channel is reserved to facilitate the airflow to enter the interior of the aerosol generating rod 500.

[0073] Furthermore, in a specific example, such as Figure 13 and Figure 14 In the example shown, the end of the support base 12 away from the abutment structure 112 has a snap-fit ​​structure 121. When the heating system 100 is applied in an atomizing device, it can form a snap-fit ​​engagement with the bracket structure of the atomizing device through the snap-fit ​​structure 121 to connect and fix the heating component 1. The number of snap-fit ​​structures 121 can be one or more. When multiple snap-fit ​​structures 121 are provided, such as... Figure 13 As shown in the diagram, the multiple snap-fit ​​structures 121 can adopt different structural forms to adapt to the mating structures on the bracket structure, thereby improving the stability of the snap-fit ​​engagement. The snap-fit ​​fixing method is simple to operate during assembly, has high assembly efficiency, and is easy to disassemble.

[0074] Furthermore, in a specific example, such as Figure 13 and Figure 14In the example, a lead wire fixing groove 122 is provided on the outer wall of the support base 12. When the heating system 100 is applied to the atomizing device, the lead wire fixing groove 122 is used to fix the lead wire of the power supply device, so as to prevent the lead wire from moving freely and interfering with other structures. The number of lead wire fixing grooves 122 can be two or more, depending on the actual use needs, and the specific number depends on the number of lead wires.

[0075] In further embodiments of this application, such as Figure 4 In the example, the heating assembly 1 also includes a heat insulation sleeve 14. The heat insulation sleeve 14 has a cylindrical structure and is disposed in the mounting cavity 111 of the support sleeve 11, covering the outside of the heating tube 13 to insulate the heating tube 13, thereby reducing the heat loss from the heating tube 13 and allowing the heat to be conducted as much as possible to the internal aerosol generating rod 500, further reducing heat loss and improving the heating efficiency of the aerosol generating rod 500. Specifically, in the first direction, the heat insulation sleeve 14 completely covers the heating tube 13 to increase the heat insulation coverage area. The heat insulation sleeve 14 can be made of insulating material to further enhance the insulation effect.

[0076] In further implementation of this application, such as Figure 4 and Figure 5 In the example, the heating assembly 1 also includes a fixing sleeve 15. The fixing sleeve 15 is located at the end of the support sleeve 11 away from the support base 12 and is fixedly connected to the support sleeve 11. The fixing sleeve 15 is a through-structure in a first direction to avoid obstructing the heating tube 13 and heating cavity 131 inside the support sleeve 11. The aerosol generating rod 500 can pass through the fixing sleeve 15 and into the heating cavity 131. The inner wall of the fixing sleeve 15 has multiple radial protrusions 151, which can be made of silicone and spaced circumferentially. When the aerosol generating rod 500 is inserted into the heating cavity 131, the radial protrusions 151 can abut against the sidewall of the aerosol generating rod 500 to fix it, preventing it from shaking and accidentally falling off during use. Figure 4 In the example, the fixed sleeve 15 has an annular slot structure 152 at one end facing the support sleeve 11. The size of the slot structure 152 is adapted to the end size of the support sleeve 11. The support sleeve 11 is partially inserted into the slot structure 152 to form a plug-in fit with the fixed sleeve 15, which facilitates assembly and disassembly.

[0077] In practical applications, such as Figure 4In the example, when the aerosol generating rod 500 is inserted into the heating chamber 131, there is a gap between the outer wall of the aerosol generating rod 500 and the inner wall of the heating tube 13 in the radial direction of the heating chamber 131, and there is also an air passage gap between the abutment structure 112 of the support sleeve 11 and the aerosol generating rod 500, so that the heating chamber 131 can exchange airflow with the outside atmosphere. When the user performs a suction action on the aerosol generating rod 500, a negative pressure can be generated in the heating chamber 131, and the outside air can enter the heating chamber 131 under the action of negative pressure, and flow into the base connecting groove 123 along the side of the aerosol generating rod 500, and then enter its interior from the bottom end of the aerosol generating rod 500, mix with the aerosol generated by the atomization of the atomizing matrix, and then flow to the suction end.

[0078] An embodiment of the second aspect of this application provides an atomizing device 400, such as... Figure 15 , Figure 16 and Figure 17 As shown, the atomizing device 400 includes a housing 410, a heating system 100 as described in any of the embodiments of the first aspect, and a power supply assembly 420. The housing 410 has a mounting opening 411 at one end in the first direction, for example... Figure 15 The housing 410 shown has an assembly port 411 at its top. Both the heating system 100 and the power supply assembly 420 are located inside the housing 410. The insertion port 1311 of the heating assembly 1 of the heating system 100 corresponds to the assembly port 411, allowing the heating chamber 131 of the assembly port 411 to communicate with it, enabling the aerosol generating rod 500 to be inserted into the heating chamber 131 of the heating assembly 1 through the assembly port 411. The power supply assembly 420 is electrically connected to the controller 3 to supply power to the heating assembly 1 under the control of the controller 3, enabling the heating assembly 1 to heat the aerosol generating rod 500 inserted into the heating chamber 131 when energized.

[0079] The following describes a specific example of the atomizing device 400 of this application with reference to the accompanying drawings.

[0080] like Figures 1 to 5 and Figures 15 to 17 As shown, the atomizing device 400 is specifically a heat-not-burning device. The housing 410 is assembled from multiple sub-housings 410 to facilitate the assembly of various internal components. The top of the housing 410 has an assembly port 411. The housing 410 has a support structure 412 inside, which divides the internal space of the housing 410 into two different chambers. The heating component 1 and the detection component 2 are located in the chamber above the support structure 412. The power supply component 420 includes an electrically connected battery 421 and an electronic control board 422. The battery 421 is located in the chamber below the support structure 412. The electronic control board 422 partially extends to the side of the heating component. The controller 3 is located on the electronic control board 422 and forms a control circuit.

[0081] like Figures 1 to 5 and Figures 15 to 17 As shown, the heating assembly 1 includes a support sleeve 11, a support base 12, a heating element 13, a heat insulation sleeve 14, and a fixing sleeve 15.

[0082] Specifically, the support sleeve 11 has a mounting cavity 111 extending along a first direction. The support base 12 is located at the bottom of the support sleeve 11, and the top of the support base 12 has a base connecting seat, which extends into the mounting cavity 111 and forms a detachable connection with the support sleeve 11. Both the support sleeve 11 and the support base 12 are made of high-temperature resistant PEEK material. The bottom end of the support base 12 has multiple snap-fit ​​structures 121, which engage with the mating structures on the bracket structure 412 to connect and fix the heating component 1 to the bracket structure 412. The fixing sleeve 15 is an annular structure and is located at the top of the support sleeve 11. The bottom end of the fixing sleeve 15 has an annular slot structure 152, into which the top of the support sleeve 11 is inserted to form a plug-in engagement with the fixing sleeve 15. The inner wall of the fixing sleeve 15 has multiple radially protruding structures 151 made of flexible material. The heat insulation sleeve 14 is located in the mounting cavity 111 and covers the outside of the heating tube 13.

[0083] The heating element 13 has a cylindrical structure and is disposed in the mounting cavity 111 of the support sleeve 11 along the first direction. The bottom end of the heating element 13 extends into the base connecting groove 123 to form an abutment with the support base 12. The inner side wall of the support sleeve 11 has an abutment structure 112 near the top end. The abutment structure 112 has an annular connecting groove. The top end of the heating element 13 extends into the connecting groove of the abutment structure 112 and forms an abutment with the abutment structure 112. The two ends of the heating element 13 are clamped and fixed by the abutment structure 112 and the support base. The internal space of the heating tube 13 is connected to the internal space of the base connecting groove 123 to form a heating cavity 131, and the base connecting groove 123 is formed with a first heating section 1312 of the heating cavity 131 for accommodating the bottom end of the aerosol generating rod 500; a first mounting hole 1231 is provided on the inner side wall of the base connecting groove 123 at a position corresponding to the first heating section 1312, and a second mounting hole 1232 is provided on the bottom wall of the base connecting groove 123.

[0084] The detection component 2 includes a light source emitter 21 and a light intensity detector 22. The light source emitter 21 is installed in a second mounting hole 1232 on the bottom wall of the base connecting groove 123, and the light intensity detector 22 is installed in a first mounting hole 1231 on the inner side wall of the base connecting groove 123. The angle α between the line connecting the light source emitter 21 and the light intensity detector 22 and the horizontal plane is not less than a first preset angle, so that the light intensity detector 22 is located within the light emission range of the light source emitter 21. A preset path is formed between the light source emitter 21 and the light intensity detector 22, and the light source emitter 21 can emit light along the preset path. The installation position of the light intensity detector 22 is the target position of the preset path, and the light intensity detector 22 can detect the light intensity at the target position. The controller 3 is communicatively connected to the detection component 2 to receive the detection data from the light intensity detector 22.

[0085] When the aerosol generating rod 500 is not inserted into the heating chamber 131, such as Figure 17 In the example, the light emitted by the light source emitter 21 can directly propagate along the preset path to the target position and be detected by the light intensity detector 22. The controller 3 identifies that there is no aerosol generating rod 500 in the heating cavity 131 based on the detection data of the light intensity detector 22, and controls the heating tube 13 of the heating component 1 to be in a shutdown state.

[0086] When the aerosol generating rod 500 is inserted into the heating chamber 131, as Figure 4 and Figure 5 In the example, the bottom end of the aerosol generating rod 500 is located in the first heating section 1312 of the base connecting groove 123, and affects the light on the preset path. The light intensity detector 22 detects the light intensity data at the target position, and the controller 3 calculates the detection data of the light intensity detector 22 and identifies the type of the corresponding aerosol generating rod 500, thereby controlling the heating tube 13 to adopt a heating method that is compatible with it, so that the atomizing matrix of the aerosol generating rod 500 can be fully atomized to improve the atomization effect.

[0087] Taking two common aerosol generating rods 500 as examples, type one has an atomizing matrix stored at the bottom, while type two has a sponge at the bottom. The light intensity at the output of the light source emitter 21 is used as the reference value C; when no aerosol generating rod 500 is inserted into the heating chamber 131, such as... Figure 17 In the example, the light intensity value detected by the light intensity detector 22 at the target location is within the range of 20% to 40% of the reference value C; when the aerosol generating rod 500 is inserted into the heating chamber 131, if the light intensity detector 22 detects that the light intensity data at the target location is within the range of 1% to 10% of the reference value C, then the controller 3 identifies the aerosol generating rod 500 as type two based on the light intensity data. Figure 5Example: If the light intensity detector 22 detects that the light intensity data at the target location is approximately equal to 0 or lower than 1% of the reference value C, the controller 3 identifies the aerosol generating rod 500 as Type 1 based on the detection data. Figure 4 Examples are shown in the text.

[0088] The atomizing device 400 in this embodiment can effectively identify different types of aerosol generating rods and control the heating component 1 to adopt a heating method that is compatible with the type of aerosol generating rod, so that the atomizing matrix can be quickly and fully atomized, thereby effectively improving the heating and atomization effect of the atomizing matrix and improving the user experience.

[0089] Furthermore, the atomizing device 400 in this embodiment also has all the beneficial effects of the heating system 100 in any of the above embodiments, which will not be repeated here.

[0090] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
