[0026] 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.

[0027] 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).

[0028] This application discloses an atomizing component that can be used in atomizing equipment employing a heating-non-combustion method to heat aerosol products.

[0029] Please refer to Figures 2 and 3. The atomizing assembly includes a heating cylinder 100, a heat insulation cylinder 200, and a base 300. The internal channel of the heating cylinder 100 is a heating channel 101, which communicates with an opening 412 on the atomizing body 400 in the atomizing device. Aerosol products can enter the heating channel 101 through the opening 412. In some embodiments, the heating cylinder 100 can heat the aerosol products in the heating channel 101 by providing a heating film or heating wire on the outer wall of the cylinder, or the heating cylinder 100 itself can be made of conductive ceramic material, and the heating cylinder 100 generates heat after being energized to heat the aerosol products. The heating cylinder 100 has an inlet end and an outlet end located at both ends in the extending direction of the heating channel 101. Airflow can enter the heating channel 101 from the inlet end and exit sequentially along the outlet end and the opening 412 of the atomizing body 400.

[0030] In some embodiments, referring to Figure 2, the heat insulation cylinder 200 is generally cylindrical and is located radially outside the heating cylinder 100. The heat insulation cylinder 200 can be arranged coaxially with the heating cylinder 100. The two ends of the heat insulation cylinder 200 in the extension direction of the heating channel 101 are a first end near the inlet end of the heating cylinder 100 and a second end near the outlet end of the heating cylinder 100, respectively. The first end of the heat insulation cylinder 200 extends radially toward the heating cylinder 100 to abut against the outlet end of the heating cylinder 100 in the extension direction of the heating channel 101.

[0031] In some embodiments, referring to Figure 2, the wall of the heat insulation cylinder 200 has an air inlet channel 250 arranged in the extending direction of the heating channel 101. The air inlet channel 250 may include an annular channel arranged around the heating cylinder 100, or it may be multiple arc-shaped channels, with adjacent arc-shaped channels spaced apart in the circumferential direction of the heating cylinder 100. The first end of the heat insulation cylinder 200 has an outward protrusion 231 arranged away from the air inlet channel 250 in the extending direction of the heating channel 101. The outward protrusion 231 is provided with an air inlet 2311 communicating with the air inlet channel 250. The atomizing body 400 of the corresponding atomizing device is provided with a perforation 413. The outward protrusion 231 can be inserted into the perforation 413 of the atomizing body 400 in the extending direction of the heating channel 101, so that the air inlet 2311 is exposed outside the atomizing body 400, facilitating the entry of external air into the air inlet channel 250 from the air inlet 2311.

[0032] In some embodiments, referring to Figure 2, the base 300 is located on the side where the inlet end of the heating cylinder 100 is located in the extending direction of the heating channel 101. The base 300 and the heat insulation cylinder 200 can clamp and fix the two ends of the heating cylinder 100 in the extending direction of the heating channel 101 to fix the position of the heating cylinder 100 in the atomizing assembly in the extending direction of the heating channel 101. Both the heat insulation cylinder 200 and the base 300 can be provided with mounting grooves facing the heating channel 101 in the extending direction of the heating channel 101. The inlet end and outlet end of the heating cylinder 100 are respectively located in the corresponding mounting grooves. The sidewall of the mounting groove cooperates with the outer sidewall of the heating cylinder 100 to restrict the fixation of the heating cylinder 100 in the plane perpendicular to the extending direction of the heating channel 101 in the atomizing assembly.

[0033] The base 300 is also sealed to the heat insulation cylinder 200, such as the inner wall of the heat insulation cylinder 200 or the outer wall of the heat insulation cylinder 200. In this way, the base 300, the heat insulation cylinder 200 and the heating cylinder 100 can be enclosed to form a heat insulation cavity 340 arranged around the heating cylinder 100. The heat insulation cavity 340 can reduce the heat transferred outward in the radial direction of the heating cylinder 100, thereby reducing heat loss and reducing the energy consumption of the atomizing component.

[0034] The base 300 has a connecting air cavity 330 inside. The connecting air cavity 330 can be arranged in the radial direction of the heating cylinder 100. In the radial direction of the heating cylinder 100, the outer radial end of the connecting air cavity 330 is connected to the air inlet channel 250, and the center of the connecting air cavity 330 is connected to the heating channel 101. In this way, the external airflow can enter the air inlet channel 250 from the air inlet 2311, and then enter the heating channel 101 from the air inlet channel 250 along the connecting air cavity 330. It mixes with the aerosol generated after the aerosol product is heated, and is discharged along the opening 412 of the atomizing body 400. Since the air inlet 2311 and the connecting air chamber 330 are located at both ends of the air inlet channel 250 in the extension direction of the heating channel 101, and the air inlet channel 250 corresponds to the position of the heating channel 101 in the extension direction of the heating channel 101, when the atomizing device is in use, the opening 412 on the atomizing body 400 usually faces upward, that is, the outlet end of the heating cylinder 100 is located above the inlet end. In this way, the airflow entering the air inlet channel 250 from the air inlet 2311 first flows downward to the bottom of the heating channel 101, then rises along the heating channel 101, and finally exits from the opening 412 of the atomizing body 400. The condensate in the heating channel 101 will enter the connecting air chamber 330 under the action of gravity, which can reduce the condensate flowing back along the air inlet channel 250, thereby reducing the probability of condensate leakage from the air inlet 2311.

[0035] In some embodiments, the heat insulation cylinder 200 and the base 300 can be an integral structure to facilitate the assembly of the atomizing component. To facilitate the fixing of the entire atomizing component within the atomizing body 400, in some embodiments, referring to Figure 3, the heat insulation cylinder 200 may have a limiting structure arranged in the extending direction of the heating channel 101. Correspondingly, a limiting engagement structure that cooperates with the limiting structure needs to be provided on the atomizing body 400. The limiting structure and the limiting engagement structure cooperate to fix the position of the atomizing component in the plane perpendicular to the extending direction of the heating channel 101, ensuring that the heating channel 101 in the atomizing component is coaxial with the opening 412 of the atomizing body 400.

[0036] Specifically, in one embodiment, referring to Figure 3, a limiting structure may be provided, including a limiting protrusion 211, and a limiting mating structure may be provided on the atomizing body 400, including a limiting recess 411. The limiting protrusion 211 may be a protruding post, and the limiting recess 411 may be a groove. The protruding post and the groove mate to achieve the assembly of the atomizing component and the atomizing body 400, which helps to fix the position of the atomizing component in the plane extending in the vertical heating channel 101 within the atomizing body 400. Of course, it is also possible to set the protruding post on the atomizing body 400 and the groove on the heat insulation cylinder 200.

[0037] In one embodiment, referring to Figure 2, a limiting structure and a limiting engagement structure can be provided, one of which is a hook 421, and the other is a slot or through hole 2211 that engages with the hook 421. For example, in one example, the hook 421 is set on the atomizing body 400, and the slot or through hole 2211 is set on the heat insulation cylinder 200. The slot opening is set towards the opening 412 of the atomizing body 400 or towards the air inlet 2311 of the atomizing component in the extending direction of the heating channel 101. The hook 421 engages with the slot, and the position of the hook 421 is limited by the side wall of the slot. Alternatively, the through hole 2211 is arranged in the extending direction of the heating channel 101, and the hook 421 passes through the through hole 2211 and engages with the end face of the through hole 2211, and the position of the hook 421 is limited by the side wall of the through hole 2211.

[0038] Please refer to Figure 2. In one embodiment, the protrusion 231 provided on the heat insulation cylinder 200 can also serve as a limiting structure to cooperate with the perforation 413 on the atomizing body 400 to ensure that the position of the atomizing component is fixed within the atomizing body 400.

[0039] In other embodiments, a positioning ring can be provided at the opening 412 of the atomizing body 400, so that the positioning ring is inserted into the first end opening of the heat insulation cylinder 200, thereby achieving coaxiality between the heating channel 101 and the opening 412 of the atomizing body 400.

[0040] In some embodiments, multiple limiting structures are provided on the heat insulation cylinder 200, such as two, three or more. The multiple limiting structures can be evenly arranged at intervals in the circumferential direction of the heating cylinder 100 to improve the assembly accuracy and positional accuracy of the atomizing component in the atomizing body 400.

[0041] Correspondingly, multiple protrusions 231 can be provided on the heat insulation cylinder 200. Multiple protrusions 231 are evenly spaced in the circumferential direction of the heating cylinder 100 to increase the number of air inlets 2311 in the atomizing assembly and ensure uniform air intake in the air intake channel 250 and the heating channel 101.

[0042] In some embodiments, referring to Figure 2, the heat insulation cylinder 200 can be configured as a split structure. The heat insulation cylinder 200 includes an inner cylinder 210, an outer cylinder 220, and a first sealing element 230. The inner cylinder 210 is located inside the outer cylinder 220 in the radial direction of the heating cylinder 100. The inner cylinder 210 and the outer cylinder 220 are arranged coaxially. Both the inner cylinder 210 and the outer cylinder 220 can be generally cylindrical. The inner cylinder 210 extends toward the heating cylinder 100 from the end of the atomizing body 400 opening 412 in its extension direction, so as to be clamped at both ends of the heating cylinder 100 with the base 300 in the extension direction of the heating channel 101. The inner cylinder 210, the base 300, and the heating cylinder 100 enclose to form a heat insulation cavity 340. The inner cylinder 210 can be made of high-temperature resistant plastic material, and the outer cylinder 220 can be made of metal material or plastic material.

[0043] The first sealing element 230 is located at the first end of the heat insulation cylinder 200 in the extending direction of the heating channel 101. The first sealing element 230 is sealed and fitted with the inner cylinder 210 and the outer cylinder 220 respectively. As in one embodiment, referring to FIG2, the first sealing element 230 has an annular structure. The first sealing element 230 has a first inner ring portion 232 and a first outer ring portion 233. The first outer ring portion 233 is connected to the radially outer side of the first inner ring portion 232. The first inner ring portion 232 can abut against the end of the inner cylinder 210 in the extending direction of the heating channel 101 to achieve a sealed fit with the inner cylinder 210. The first outer ring portion 233 extends toward the base 300 in the extending direction of the heating channel 101. The radially inner side of the first outer ring portion 233 has a plurality of annular protrusions. The first outer ring portion 233 is located on the radially outer side of the outer cylinder 220. The first outer ring portion 233 is sealed and fitted with the outer cylinder 220 through the plurality of annular protrusions.

[0044] In embodiments where the limiting structure includes a limiting protrusion 211 or a limiting groove, please refer to Figure 3. The limiting structure can be provided on the inner cylinder 210 or on the outer cylinder 220. Correspondingly, a sealing hole 234 is provided on the first sealing member 230. The limiting protrusion 211 and the sealing hole 234 are sealed together. The limiting protrusion 211 passes through the sealing hole 234 and cooperates with the limiting recess 411.

[0045] In embodiments where the limiting structure includes a slot or through hole 2211, please refer to Figure 2. A radially extending lug 221 can be provided on the outer wall surface of the outer cylinder 220. The limiting structure, such as the through hole 2211, is provided on the lug 221 to cooperate with the hook 421 arranged on the atomizing body 400 facing the lug 221.

[0046] In some embodiments, please refer to FIG2, the protrusion 231 on the heat insulation cylinder 200 may be disposed on the first sealing member 230, the first sealing member 230, the inner cylinder 210 and the outer cylinder 220 surround to form an air inlet cavity 240, the air inlet cavity 240 may be an annular cavity or may also include multiple arc-shaped cavities arranged at intervals around the heating cylinder 100, and the air inlet 2311 communicates with the air inlet channel 250 through the air inlet cavity 240.

[0047] To increase the air intake, in one embodiment, a radially penetrating hole can be provided on the first inner ring portion 232 as a gas inlet. The airflow entering the atomizing body 400 from the opening 412 can enter the air intake chamber 240 from the gas inlet on the first inner ring portion 232 to increase the air intake of the atomizing component.

[0048] The air intake channel 250 is located between the inner cylinder 210 and the outer cylinder 220. In one embodiment, the air intake channel 250 may include an annular channel or may also include multiple arc-shaped channels arranged at intervals around the heating cylinder 100. When the air intake channel 250 includes multiple arc-shaped channels, the number of arc-shaped channels is equal to or less than the number of arc-shaped cavities to ensure that each arc-shaped channel can be connected to the air intake port 2311 through the arc-shaped cavity.

[0049] In some embodiments, in order to ensure the shape of the arc-shaped channel, one of the inner cylinder 210 and the outer cylinder 220 is provided with a positioning protrusion 212 and the other with a positioning recess 222. The positioning protrusion 212 and the positioning recess 222 cooperate to limit the relative position of the inner cylinder 210 and the outer cylinder 220 in the circumferential direction of the heating cylinder 100.

[0050] Referring to Figure 4, in one embodiment, the positioning protrusion 212 can be disposed at the end of the inner cylinder 210. The positioning protrusions 212 can be arranged in pairs, and the two pairs of positioning protrusions 212 are connected in the circumferential direction of the heating cylinder 100 to facilitate the setting of a parting surface on the inner cylinder 210 and to facilitate the processing and manufacturing of the inner cylinder 210. There are multiple pairs of positioning protrusions 212, such as two pairs. The two pairs of positioning protrusions 212 are arranged in the radial direction of the heating cylinder 100, which helps to fix the position of the inner cylinder 210 inside the outer cylinder 220. The positioning recess 222 is disposed at the end of the outer cylinder 220. Corresponding to the positioning recess 222, a dovetail-shaped guide rib 223 is provided between the two positioning recesses 222 arranged in pairs. The dovetail-shaped guide rib 223 can cooperate with the dovetail-shaped groove between the two positioning protrusions 212 arranged in pairs to limit the relative swaying of the inner cylinder 210 and the outer cylinder 220 in the radial direction of the heating cylinder 100. A protruding rib 2231 can also be provided on the side of the dovetail-shaped guide rib 223. The protruding rib 2231 presses against the side of the positioning protrusion 212 in the circumferential direction of the heating cylinder 100 to limit the relative swaying of the inner cylinder 210 and the outer cylinder 220 in the circumferential direction of the heating cylinder 100.

[0051] In some embodiments, the air intake channel 250 includes an annular channel. To increase the flow area of ​​the air intake channel 250, referring to Figure 3, the size of the positioning protrusion 212 is smaller than the size of the inner cylinder 210 in the extension direction of the heating channel 101. Multiple positioning protrusions 212 can be provided at intervals in the extension direction of the heating channel 101, or the sum of the sizes of multiple positioning protrusions 212 in the extension direction of the heating channel 101 can be smaller than the size of the inner cylinder 210. In this way, an annular channel can be formed between the inner cylinder 210 and the outer cylinder 220 in the extension direction of the heating channel 101 where no positioning protrusions 212 and positioning recesses 222 are provided, thereby increasing the flow cross-sectional area of ​​the air intake channel 250 and ensuring the flow rate of the air intake channel 250.

[0052] Of course, in other embodiments, the positioning protrusion 212 and the positioning recess 222 may also penetrate the inner cylinder 210 and the outer cylinder 220 in the extending direction of the heating channel 101, so that the air intake channel 250 includes two arc-shaped channels arranged circumferentially upwards in the heating cylinder 100.

[0053] In one embodiment, the first sealing element 230 may further include a sealing ring. The inner cylinder 210 and the outer cylinder 220 are sealed together by the sealing ring. The inner cylinder 210 is inserted into the outer cylinder 220 by the sealing ring. The inner cylinder 210 and the outer cylinder 220 are engaged by a positioning protrusion 212 and a positioning recess 222 to ensure the relative position between the inner cylinder 210 and the outer cylinder 220. A radially extending portion can be provided at the end of the inner cylinder 210 and / or the outer cylinder 220, and the outer protrusion 231 can be disposed on this radially extending portion to achieve communication between the air inlet 2311 and the air intake channel 250. Of course, in this embodiment, the first sealing element 230 does not have a sealing hole 234, and the limiting protrusion 211 can directly engage with the limiting recess 411.

[0054] In some embodiments, referring to Figure 2, the base 300 can be configured as a split structure, including a base 310 and a second sealing member 320. The base 310 abuts against the end of the opposite opening 412 of the heating cylinder 100 in the extending direction of the heating channel 101. The base 310 and the inner cylinder 210 are clamped and fixed at both ends of the heating cylinder 100 in the extending direction of the heating channel 101. The base 310 can be sealed and inserted into the inner cylinder 210. A sealing ring is installed on the outer peripheral surface of the base 310, and the base 310 is connected to the inner cylinder through the sealing ring. The inner circumferential surface of the 210 is sealed. The base 310, the inner cylinder 210 and the heating cylinder 100 enclose and form a heat insulation cavity 340. The base 310 has a radial protrusion 311 and the end of the inner cylinder 210 has a notch 213. The radial protrusion 311 and the notch 213 cooperate to limit the relative position of the base 310 and the inner cylinder 210 in the circumferential direction of the heating cylinder 100. The base 310 has a groove that communicates with the heating channel 101. The bottom wall of the groove is provided with a plurality of spaced through holes that penetrate the base 310 in the extending direction of the heating channel 101.

[0055] The second seal 320 is located on the side of the base 310 facing away from the heating cylinder 100 in the extending direction of the heating channel 101. The second seal 320 has an annular structure and has a second inner ring portion 321 and a second outer ring portion 322. The second inner ring portion 321 is connected to the radially outer side of the second outer ring portion 322. The second inner ring portion 321 abuts against the base 310 in the extending direction of the heating channel 101, and the second outer ring portion 322 faces the heating cylinder 100 in the extending direction of the heating channel 101. Extending in the direction of the heating cylinder 100, the second outer ring portion 322 has multiple annular protrusions on its radially inner side. The second outer ring portion 322 is located on the radially outer side of the outer cylinder 220. The second outer ring portion 322 is sealed to the outer cylinder 220 through multiple annular protrusions. The outer cylinder 220 is provided with a radially inner protrusion 224 at the notch 213 position of the inner cylinder 210. The radially inner protrusion 224 can abut against the base 310 in the extending direction of the heating channel 101 to prevent the base 310 from falling out of the inner cylinder 210.

[0056] The second sealing element 320, outer cylinder 220, inner cylinder 210 and base 310 enclose a cavity. The second inner ring 321 has a notch that communicates with the cavity, so as to form a communicating air cavity 330 between the base 310 and the second sealing element 320. The air inlet channel 250 between the inner cylinder 210 and the outer cylinder 220 can communicate with the heating channel 101 through the communicating air cavity 330 and the through hole on the base 310.

[0057] In one embodiment, the second seal 320 is made of rubber material and has a thin-walled portion 324 arranged corresponding to the heating channel 101 in the extending direction of the heating channel 101. The second seal 320 also has an annular sealing portion 323 extending away from the heating channel 101. The atomizing body 400 has a sealing protrusion 422, which seals against the annular sealing portion 323 to form an induction chamber 3 between the atomizing body 400 and the second seal 320. 25. The side wall of the annular sealing part 323 has a mounting hole 3231 for mounting a pressure sensor. The mounting hole 3231 communicates with the sensing air chamber 325. The thin-walled part 324 is located radially inside the annular sealing part 323. The thin-walled part 324 is located between the communicating air chamber 330 and the sensing air chamber 325. The thin-walled part 324 is located on one side of the heating channel 101 in the extending direction of the heating channel 101. The thin-walled part 324 can deform according to the change of air pressure in the communicating air chamber 330.

[0058] When the atomizing device is in operation, during suction, the airflow enters the heating channel 101 from the air inlet 2311, the air inlet channel 250, and the connecting air chamber 330. A negative pressure is generated in the connecting air chamber 330. Under the action of the negative pressure, the thin-walled part 324 protrudes towards the heating channel 101. The air pressure sensor is triggered when the air pressure changes in the sensing air chamber 325, and the atomizing component starts to work. When not suctioning, the pressure in the connecting air chamber 330 and the sensing air chamber 325 are equal, and the thin-walled part 324 protrudes towards the sensing air chamber 325 under the action of gravity.

[0059] This application also discloses an atomizing device, which includes an atomizing body 400 and an atomizing component as described in any of the above embodiments. Referring to Figures 1 to 3, the atomizing body 400 includes an atomizing shell 410, which has a cavity. The atomizing component is installed in the cavity. The atomizing shell 410 has an opening 412 communicating with the heating channel 101. The atomizing shell 410 has a perforation 413 communicating with the cavity. The perforation 413 is located near the opening 412. The outward protrusion 231 of the heat insulation cylinder 200 is located in the perforation 413, so that the air inlet 2311 is exposed on the atomizing shell 410, which facilitates the entry of external air into the air intake channel 250 along the air inlet 2311. The atomizing shell 410 has a split structure to facilitate the processing of the atomizing shell 410. A limiting fit structure that cooperates with the upper limit structure of the heat insulation cylinder 200 is provided on the atomizing shell 410.

[0060] In one embodiment, the atomizing body 400 further includes a support 420, which is installed within the cavity of the atomizing housing 410. The support 420 and the atomizing assembly are arranged in the extending direction of the heating channel 101. In embodiments where the limiting structure includes a slot or through hole 2211, a hook 421 may be provided on the support 420, extending towards the atomizing assembly to engage with the slot or through hole 2211 on the heat insulation cylinder 200.

[0061] A sealing protrusion 422 is disposed on the bracket 420 and is disposed toward the atomizing component in the extending direction of the heating channel 101 to facilitate cooperation with the annular sealing portion 323 on the second seal 320.
