[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0037] 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.
[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0039] An aerosol generator is a special atomizing product containing an atomizing matrix. When in use, it is inserted into a matching atomizing device. The heater heats the aerosol generator, causing the atomizing matrix inside the aerosol generator to atomize and generate an aerosol. As the user draws in the aerosol generator, the aerosol moves with the airflow to the suction end.
[0040] The aerosol generating apparatus and atomizing device provided in this application, by providing a first clamping part and a second clamping part at intervals along a first direction in the receiving cavity of the support component, can clamp and fix different areas on the aerosol generating rod respectively through the first clamping part and the second clamping part when the aerosol generating rod is inserted into the receiving cavity, so as to form multiple clamping, which is beneficial to improve the assembly stability of the aerosol generating rod.
[0041] The following describes some embodiments of the aerosol generating apparatus and atomizing device provided in this application with reference to the accompanying drawings.
[0042] It should be noted that, for ease of description, in the following embodiments, the height direction of the atomizing device is taken as the first direction, the width direction of the atomizing device is taken as the second direction, and the thickness direction of the atomizing device is taken as the third direction.
[0043] An embodiment of the first aspect of this application provides an aerosol generating apparatus 100, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the device includes a support assembly 1 and a heating element 2. The support assembly 1 has a receiving cavity 15. In a first direction, one end of the receiving cavity 15 has a first opening 151, which allows an aerosol generating rod 500 to pass through and be inserted into the receiving cavity 15. The heating element 2 is disposed in the receiving cavity 15 to heat the aerosol generating rod 500, causing the atomizing matrix stored within the aerosol generating rod 500 to be atomized and generate aerosol. The support assembly 1 also has an air inlet channel 16. One end of the air inlet channel 16 communicates with the first opening 151, and the other end of the air inlet channel 16 communicates with the end of the receiving cavity 15 away from the first opening 151, allowing external air to enter the receiving cavity 15 through the first opening 151 and the air inlet channel 16. During the suction operation, the airflow can be drawn into the aerosol generating rod 500 and carry the generated aerosol towards the suction end. The first clamping part 111 and the second clamping part 131 are provided on the inner side wall of the receiving cavity 15 of the support component 1. The first clamping part 111 and the second clamping part 131 are spaced apart along the first direction so that when the aerosol generating rod 500 is inserted into the receiving cavity 15, multiple clamping of the aerosol generating rod 500 can be achieved so that the aerosol generating rod 500 remains stable.
[0044] It is understandable that in existing atomization devices, the clamping area of the aerosol generating rod is usually located above the atomization matrix storage area. However, during use, the clamping area is prone to deformation after being heated, causing the clamping to loosen and the aerosol generating rod to fall off.
[0045] The aerosol generating device 100 in this embodiment improves and optimizes the structure by using the first clamping part 111 and the second clamping part 131, which are spaced apart in the first direction in the receiving cavity 15, to clamp and fix different areas on the aerosol generating rod 500. This can effectively improve the assembly stability of the aerosol generating rod 500. Moreover, it can use the first opening 151 inserted into the aerosol generating rod 500 to introduce air. When applied to atomizing equipment, it is not necessary to set a corresponding air inlet on the main housing 410, which helps to simplify the structure.
[0046] It should be noted that in practical applications, one or more first clamping parts 111 or one or more second clamping parts 131 can be provided as needed. Both the first clamping parts 111 and the second clamping parts 131 can independently clamp and fix the aerosol generating rod 500.
[0047] In further embodiments of this application, such as Figure 1 , Figures 3 to 5As shown, in the aerosol generating device 100, the support assembly 1 includes a first sealing element 11, a heat insulation sleeve 12, and a support base 13. The first sealing element 11 has a through hole 110 extending in a first direction; the heat insulation sleeve 12 is disposed at one end of the first sealing element 11 in the first direction and is sealed to the first sealing element 11; the internal space of the heat insulation sleeve 12 corresponds to and communicates with the through hole 110 of the first sealing element 11, and the heating element 2 is disposed inside the heat insulation sleeve 12. The support base 13 is connected to the end of the heat insulation sleeve 12 away from the first sealing element 11, and the end of the support base 13 facing the first sealing element 11 has a slot 130, which corresponds to the interior of the heat insulation sleeve 12 and forms a receiving cavity 15 with the heat insulation sleeve 12 and the through hole 110. The outer end of the through hole 110 forms the first opening 151 of the receiving cavity 15. When in use, the aerosol generating rod 500 can pass through the through hole 110 and the heat insulation through hole and extend into the slot 130 of the support base 13; the bottom wall of the slot 130 is provided with a vent hole 132. When the suction action is performed, the airflow in the air intake channel 16 can pass through the vent hole 132 into the slot 130 and be sucked into the aerosol generating rod 500. The inner wall of the through hole 110 has a first contact 1111, which can abut against the side wall of the aerosol generating rod 500 to form a first clamping part 111, which can laterally clamp the area where the aerosol generating rod 500 passes through the through hole 110; the inner wall of the slot 130 has a second contact 1311, which can abut against the side wall of the aerosol generating rod 500 to form a second clamping part 131, which can laterally clamp the area where the aerosol generating rod 500 is inserted into the slot 130.
[0048] A first clamping portion 111 is formed by the first contact member 1111 within the first sealing member 11, and a second clamping portion 131 is formed by the second contact member 1311 in the support base 13. When the aerosol generating rod 500 is inserted into the receiving cavity 15, the second contact member 1311 forms an abutment clamp with the side wall near the inner end of the aerosol generating rod 500, and the first contact member 1111 forms an abutment clamp above the atomization matrix storage area of the aerosol generating rod 500, thereby forming a segmented clamping fixation, which can effectively enhance the assembly stability of the aerosol generating rod 500. During use, even if the clamping area corresponding to the first contact member 1111 in the aerosol generating rod 500 deforms due to heat, the second contact member 1311 can still clamp and fix the aerosol generating rod 500, thereby preventing the aerosol generating rod 500 from falling off.
[0049] It should be noted that in practical applications, the number of the first contact 1111 and the second contact 1311 can be set to one or more, and the specific number can be set according to the actual usage requirements.
[0050] In a specific example, such as Figures 3 to 6 In the example shown, there are multiple first contacts 1111, and these multiple first contacts 1111 are spaced apart in the circumferential direction of the through hole 110 to form abutment clamping at different positions in the circumferential direction of the aerosol generating rod 500. Preferably, the multiple first contacts 1111 are evenly arranged in the circumferential direction so that the force is relatively uniform when clamping the aerosol generating rod 500.
[0051] In a specific example, such as Figures 3 to 6 In the example, the first contact 1111 is specifically an elastic protrusion structure, which protrudes radially inward along the through hole 110. When the aerosol generating rod 500 passes through the through hole 110, the outer wall abuts against the elastic protrusion structure, and can exert a certain amount of pressure on the elastic protrusion structure in the radial direction, causing the elastic protrusion structure to undergo slight deformation and tend to return to its original shape, thereby forming an elastic clamping effect on the aerosol generating rod 500. Preferably, the first contact 1111 and the first sealing member 11 are integrally formed structures, and the whole is made of a material with a certain degree of elasticity, such as silicone. In particular, during the heating process, when the clamping area on the aerosol generating rod 500 corresponding to the first contact 1111 deforms due to heat, the elastic protrusion structure can produce a matching elastic deformation to maintain the abutment state with the aerosol generating rod 500, resulting in a better clamping effect.
[0052] Furthermore, in a specific example, such as Figures 3 to 5 as well as Figure 7 As shown, the second contact 1311 specifically adopts a rigid ridge structure, which protrudes inward in the radial direction of the slot 130 and extends along the first direction. When the aerosol generating rod 500 is inserted into the slot 130, the outer wall can form an abutment fit with the rigid ridge structure, so that the aerosol generating rod 500 is pressed in the radial direction, thereby forming a clamping fixation. It can be understood that since the part of the aerosol generating rod 500 inserted into the slot 130 is near the end and is not the area storing the atomizing matrix, this area generally does not need to be heated, so the possibility of deformation is small. Using a rigid ridge structure to abut and clamp this part can meet the usage requirements and is easy to process. Preferably, the rigid ridge structure can be integrally formed with the support base 13, for example, made of ceramic material.
[0053] In a specific example, such as Figures 3 to 5 as well as Figure 7As shown, within the slot 130 of the support base 13, a plurality of second contact elements 1311 are arranged at circumferential intervals to abut against different positions of the aerosol generating rod 500 in the circumferential direction, thereby forming a multi-point clamping and fixing of the aerosol generating rod 500 in the radial direction. Preferably, the plurality of second contact elements 1311 are evenly arranged in the circumferential direction, so that the force distribution is more uniform and the stability is better when clamping and fixing the aerosol generating rod 500.
[0054] Furthermore, such as Figures 3 to 5 as well as Figure 7 As shown, the second contact 1311 has a beveled structure at one end facing the first seal 11, and in the first direction, the beveled structure is inclined away from the first seal 11 to guide the aerosol generating rod 500 during insertion into the slot 130, so that the aerosol generating rod 500 can be easily aligned with the slot 130 and quickly inserted into the slot 130, which helps to simplify the operation.
[0055] In further embodiments of this application, such as Figures 3 to 5 as well as Figure 8 , Figure 9 As shown, a first abutment structure 121 is provided on the inner wall of the end of the heat insulation sleeve 12 facing the first sealing member 11, and the first abutment structure 121 is arranged along the circumference of the heat insulation sleeve 12; correspondingly, a second abutment structure 133 is provided on the inner wall of the slot 130 of the support base 13 facing the first sealing member 11, and the second abutment structure 133 is arranged along the circumference of the slot 130, and in the first direction, the second abutment structure 133 is arranged opposite to the first abutment structure 121. The heating element 2 specifically includes a heating tube 21, which is arranged in the heat insulation sleeve 12 along the first direction. One end of the heating tube 21 abuts against the first abutment structure 121, and the other end of the heating tube 21 extends into the slot 130 and abuts against the second abutment structure 133, so that the heating tube 21 is clamped from both ends by the first abutment structure 121 and the second abutment structure 133, so that the heating tube 21 is kept fixed. When the aerosol generating rod 500 is inserted into the receiving cavity 15, it can pass through the heating tube 21 and be inserted into the slot 130. The heating tube 21 can heat the aerosol generating rod 500 in the circumferential direction, so that the aerosol generating rod 500 is heated more evenly.
[0056] Specifically, such as Figure 5 and Figure 9 In the example, the first abutting structure 121 and the second abutting structure 133 can adopt an annular step structure to adapt to the shape of the heating tube 21; of course, the first abutting structure 121 and / or the second abutting structure 133 can also be set as circumferentially spaced protrusion structures according to actual needs, so as to abut the end of the heating tube 21, and also to fix and support the heating tube 21.
[0057] It should be noted that the heating element 2 is not limited to the heating tube 21 in the above embodiment, and may also be a heating plate, heating mesh or other structural forms as needed.
[0058] In one specific implementation, such as Figures 3 to 5 As shown, in the first direction, the end of the heat insulation sleeve 12 facing the first seal 11 is provided with a first mounting groove 122. At least a portion of the first seal 11 is disposed in the first mounting groove 122, and the first seal 11 is sealed and fitted with the inner sidewall of the first mounting groove 122 to form a sealed connection with the heat insulation sleeve 12 and to support and fix the first seal 11.
[0059] Furthermore, such as Figures 3 to 5 In the example, the support assembly 1 further includes a second seal 14. The second seal 14 is sealed to the end of the heat insulation sleeve 12 away from the first seal 11. A first air passage 161 is formed on the inner wall of the first seal 11, which communicates with the through hole 110 and extends through the end of the first seal 11 toward the heat insulation sleeve 12 in a first direction; correspondingly, a second air passage 162 is formed in the inner wall of the heat insulation sleeve 12, which communicates with the first air passage 161 to form an air intake passage 16. The second sealing member 14 blocks the other end of the second air passage 162, and there is a certain space between the second sealing member 14 and the support base 13, forming an air guide cavity 17; the air guide cavity 17 is connected to the vent hole 132, and a side opening 142 is provided on the side wall of the air guide cavity 17, and the side opening 142 is connected to the second air passage 162, so that the second air passage 162 is connected to the air guide cavity 17 through the side opening 142, and a relatively closed airflow space is formed. The airflow in the second air passage 162 can be turned through the side opening 142 and enter the air guide cavity 17, and then pass through the vent hole 132 into the interior of the aerosol generating rod 500 in the slot 130.
[0060] Furthermore, in a specific example, such as Figures 3 to 5 and Figure 9 As shown, the second airway 162 is specifically an annular airway, meaning it surrounds the receiving cavity 15. In the circumferential direction, the first airway 161 and the side opening 142 are spaced apart; that is, in the first direction, the first airway 161 and the side opening 142 are slightly misaligned. After the airflow enters the second airway 162 from the first airway 161, it needs to move a certain distance in the first direction while simultaneously moving a certain distance in the circumferential direction, forming a spiral motion, before entering the air guide cavity 17 through the side opening 142. Preferably, as... Figure 3 and Figure 4In the example, the side opening 142 is 90° away from the first air passage 161 in the circumferential direction, and a side opening 142 is provided on each of the opposite sides of the receiving cavity 15, so that after the airflow enters the second air passage 162, it needs to go around to the side of the receiving cavity 15 and can enter the air guide cavity 17 through the corresponding side opening 142. Moreover, air can be introduced at the same time through the two side openings 142, which is more efficient.
[0061] In one specific implementation, such as Figures 3 to 5 as well as Figure 10 As shown, in the first direction, the second sealing member 14 has a second mounting groove 141 at one end facing the first sealing member 11. The end of the heat insulation sleeve 12 away from the first sealing member 11 extends into the second mounting groove 141 and seals against the inner wall of the second mounting groove 141 to achieve a sealed connection with the second sealing member 14. Preferably, a side opening 142 is provided on the inner wall of the second mounting groove 141, and the side opening 142 is correspondingly provided with the second air passage 162 of the heat insulation sleeve 12. Correspondingly, the diameter between the end of the support base 13 inserted into the second mounting groove 141 and the bottom of the second mounting groove 141 forms an air guide cavity 17, so that the second air passage 162 communicates with the air guide cavity 17 through the side opening 142.
[0062] It should be noted that the second sealing element 14 in the above embodiments can be a flexible structure made of silicone material to improve assembly sealing and provide a cushioning effect. Sealing ridges can be provided on the inner wall of the second mounting groove 141 to enhance the sealing effect.
[0063] In further embodiments of this application, such as Figures 3 to 5 as well as Figure 11 As shown, the second seal 14 also has a sensor mounting groove 144. For example, a sensor mounting groove 144 is provided at the end of the second seal 14 away from the heat insulation sleeve 12, and an airflow sensor 3 is sealed and installed in the sensor mounting groove 144. Correspondingly, the second seal 14 has a flexible diaphragm 143, and the flexible diaphragm 143 separates the sensor mounting groove 144 and the air guide cavity 17 into two independent chambers; the flexible diaphragm 143 can deform and displace under the action of air pressure in the air guide cavity 17. When the user performs a suction action, the gas in the air guide cavity 17 is drawn into the aerosol generating rod 500 in the slot 130. Under the action of negative pressure, the flexible diaphragm 143 deforms and displaces towards the air guide cavity 17, and causes the air pressure in the sensor mounting groove 144 to change. At this time, the airflow sensor 3 senses the change in air pressure and generates a corresponding sensing signal as a characterization signal of the airflow movement in the air guide cavity 17. When the aerosol generating device 100 is applied to the atomizing device, the airflow sensor 3 can be electrically connected to the power supply component.

[0065] The following describes a specific example of the atomizing device 400 of this application with reference to the accompanying drawings.
[0066] like Figures 1 to 15 As shown, the atomizing device 400 is specifically a heat-not-burn atomizing device. The height direction is the first direction, the width direction is the second direction, and the thickness direction is the third direction. The top of the main unit housing 410 has an insertion port 411, as shown... Figures 3 to 5 as well as Figure 14 , Figure 15As shown, a support structure 430 is provided inside the main housing 410, and the support structure 430 divides the internal space of the main housing 410 into different chambers. The support assembly 1 of the aerosol generating device 100 includes a first sealing element 11, a heat insulation sleeve 12, a support base 13, and a second sealing element 14, which are arranged sequentially in a first direction. The bottom of the second sealing element 14 is connected to the support structure 430, and the bottom of the heat insulation sleeve 12 is inserted into the second mounting groove 141 of the second sealing element 14 and seals with the inner sidewall of the second mounting groove 141. The top of the heat insulation sleeve 12 has a first mounting groove 122, a portion of the first sealing element 11 is disposed in the first mounting groove 122 and seals with the inner sidewall of the first mounting groove 122, and the top of the first sealing element 11 abuts against the top wall of the main housing 410. The first sealing element 11 is specifically an annular silicone structure with a through hole 110 corresponding to the insertion port 411. Multiple flexible first contact elements 1111 are arranged circumferentially on the inner sidewall of the through hole 110 to form a first clamping part 111. A first air passage 161 is also provided on the inner sidewall of the first sealing element 11 facing the heat insulation sleeve 12. The first air passage 161 communicates with the through hole 110 and passes through the end of the first sealing element 11 away from the insertion port 411 in the first direction. The internal space of the heat insulation sleeve 12 is correspondingly arranged and communicates with the through hole 110. The support base 13 is disposed in the second mounting groove 141 and is correspondingly disposed at the end of the heat insulation sleeve 12 away from the first seal 11. Part of the support base 13 extends into the heat insulation sleeve 12 and forms a slot 130. The slot 130 communicates with the heat insulation sleeve 12 and the through hole 110 to form a receiving cavity 15. The aerosol generating rod 500 can pass through the insertion port 411, the through hole 110 and the heat insulation sleeve 12 in sequence and be inserted into the slot 130.
[0067] The inner wall of the heat insulation sleeve 12 facing the insertion port 411 has an annular first abutment structure 121. The end of the first abutment structure 121 away from the insertion port 411 along the first direction forms a stepped structure. The end of the first abutment structure 121 facing the insertion port 411 has a positioning protrusion 123, which is inserted and engaged with the corresponding positioning hole on the end face of the first seal 11 for easy assembly. A second air passage 162 surrounding the receiving cavity 15 is formed in the side wall of the heat insulation sleeve 12. The second air passage 162 is isolated from the receiving cavity 15, and the top of the second air passage 162 is connected to the first air passage 161 to form an air intake passage 16. The bottom of the second air passage 162 is an open structure and is sealed to the bottom wall of the second mounting groove 141. Two side openings 142 are formed on the inner side wall of the second mounting groove 141 near the bottom wall. The two side openings 142 are 180° apart in the circumferential direction, and each side opening 142 is 90° apart from the first air passage 161. An annular second abutment structure 133 is formed on the inner side wall of the slot 130, and the second abutment structure 133 is specifically in the form of a stepped structure. The inner side wall of the slot 130 also has a plurality of second contact members 1311 extending along the first direction. The second contact members 1311 are all hard convex structures, and the plurality of second contact members 1311 are evenly arranged in the circumferential direction of the slot 130. A plurality of vent holes 132 extending along the first direction are formed on the bottom wall of the slot 130. A venting cavity 17 is formed between the bottom of the support base 13 and the bottom wall of the second mounting groove 141, and the venting cavity 17 is connected to the side opening 142 and the vent hole 132. The heating element 2 specifically adopts the structure of a heating tube 21. The heating tube 21 is arranged in the heat insulation sleeve 12 along the first direction. One end of the heating tube 21 abuts against the first abutting structure 121, and the other end extends into the slot 130 and abuts against the second abutting structure 133. The outer wall of the heating tube 21 has a heating resistor and a lead structure 211. The lead structure 211 extends outward through the wire groove 134 on the outside of the support base 13 and the second sealing member 14.
[0068] like Figure 14 and Figure 15 In the example, the bottom of the second seal 14 has a sensor mounting groove 144, in which an airflow sensor 3 is sealed and installed. Correspondingly, the bottom wall of the second mounting groove 141 has a flexible diaphragm 143. The upper part of the flexible diaphragm 143 is an air guide cavity 17, and the lower part is a sensor cavity mounting groove. The flexible diaphragm 143 can deform and move under air pressure. The power supply assembly 420 is located in another cavity inside the main unit housing 410, specifically including a battery 421 and an electronic control board 422 that are electrically connected. The electronic control board 422 is provided with a control circuit and is electrically connected to the airflow sensor 3 and the pin structure 211 of the heating tube 21. The power supply state of the battery 421 to the heating tube 21 is controlled by the electronic control board 422.
[0069] When using, such as Figures 3 to 5 as well as Figure 14 , Figure 15 In the example, the aerosol generating rod 500 can be inserted through the insertion port 411 and through the heating tube 21 into the slot 130 of the support base 13. Multiple hard protruding structures on the inner sidewall of the slot 130 abut against and fix the aerosol generating rod 500 to the sidewall. At the same time, multiple first contact members 1111 on the inner sidewall of the through hole 110 of the first sealing member 11 abut against and fix the aerosol generating rod 500 through the through hole 110 to form a double clamping of the aerosol generating rod 500. When the user performs a suction action on the aerosol generating rod 500, the gas in the air guiding chamber 17 is drawn into the aerosol generating rod 500, creating a negative pressure in the air guiding chamber 17. Under the action of the negative pressure, the flexible diaphragm 143 deforms and moves towards the air guiding chamber 17, causing a change in the air pressure in the sensor mounting slot 144. This causes the airflow sensor 3 to sense and generate a sensing signal. The electronic control board 422 controls the battery 421 to supply power to the heating element 2 according to the sensing signal, so that the heating tube 21 heats up to heat the aerosol generating rod 500. At the same time, external air enters the first air passage 161 through the through hole 110, then enters the air guiding chamber 17 through the second air passage 162 and the side opening 142, and finally enters the slot 130 through the vent hole 132 and is drawn into the aerosol generating rod 500. The airflow mixes with the aerosol generated inside the aerosol generating rod 500 and flows towards the suction end of the aerosol generating rod 500.
[0070] In this embodiment, the atomizing device 400 uses a first contact 1111 on the inner wall of the through hole 110 and a second contact 1311 on the inner wall of the slot 130 to clamp and fix different areas on the aerosol generating rod 500, forming a double clamping. Moreover, the first contact 1111 has an elastic protrusion structure, so even if the corresponding clamping area on the aerosol generating rod 500 deforms to a certain extent due to heat, the first contact 1111 can still produce corresponding elastic deformation to maintain the clamping state. At the same time, the second contact 1311 adopts a hard convex ridge structure, which can squeeze and clamp the area near the inner end of the aerosol generating rod 500, so that the aerosol generating rod 500 maintains high assembly stability and is not easy to fall off during use. In addition, the atomizing device 400 can achieve air intake through the insertion port 411, without the need to set an additional air intake port on the main body housing 410, which is beneficial to simplify the structure and is easy to promote and apply.
[0071] Furthermore, the atomizing device 400 in this embodiment also has all the beneficial effects of the aerosol generating device 100 in any of the above embodiments, which will not be repeated here.
[0072] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
