Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0027] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0028] An embodiment of the present application discloses an atomization assembly, which can be used in an atomization device that adopts a heat-without-combustion method to achieve heating of an aerosol product.

[0029] Please refer to Figure 2 and Figure 3 The atomizing assembly includes a heating tube 100, an insulating tube 200 and a base 300. The internal channel of the heating tube 100 is a heating channel 101. The heating channel 101 is used to communicate with the opening 412 on the atomizing body 400 in the atomizing device. The aerosol product can enter the heating channel 101 from the opening 412. In some embodiments, the heating tube 100 can be implemented by providing a heating film or heating wire on the outer wall of the cylinder to heat the aerosol product in the heating channel 101, or the heating tube 100 itself can be made of conductive ceramic material. When the heating tube 100 is powered on, it generates heat to heat the aerosol product. The heating tube 100 has an inlet end and an outlet end located at both ends of the heating channel 101 in the extension direction of the heating channel 101. The airflow can enter the heating channel 101 from the inlet end and be discharged along the outlet end and the opening 412 of the atomizing body 400 in sequence.

[0030] For some examples, please refer to Figure 2 The insulating tube 200 is generally a cylindrical structure. The insulating tube 200 is located radially outside the heating tube 100. The insulating tube 200 can be arranged coaxially with the heating tube 100. The two ends of the insulating tube 200 in the extension direction of the heating channel 101 are respectively a first end close to the inlet end of the heating tube 100 and a second end close to the outlet end of the heating tube 100. The first end of the insulating tube 200 extends toward the heating tube 100 in the radial direction of the heating tube 100 so as to abut against the outlet end of the heating tube 100 in the extension direction of the heating channel 101.

[0031] For some embodiments, please refer to Figure 2The wall of the heat-insulating cylinder 200 has an air inlet channel 250 arranged in the extension direction of the heating channel 101. The air inlet channel 250 may include an annular channel arranged around the heating cylinder 100, or may also be a plurality of arc-shaped channels, with two adjacent arc-shaped channels spaced apart in the circumferential direction of the heating cylinder 100. The first end of the heat-insulating cylinder 200 has an outer protrusion 231 arranged in the extension direction of the heating channel 101 facing away from the air inlet channel 250. The outer protrusion 231 is provided with an air inlet port 2311 communicating with the air inlet channel 250. The corresponding atomizing device's atomizing body 400 is provided with a through-hole 413. The outer protrusion 231 can be inserted into the through-hole 413 of the atomizing body 400 in the extension direction of the heating channel 101, so that the air inlet port 2311 is exposed to the atomizing body 400, making it convenient for external air to enter the air inlet channel 250 from the air inlet port 2311.

[0032] For some embodiments, please refer to Figure 2 The base 300 is located on the side of the inlet end of the heating tube 100 in the extension direction of the heating channel 101. The base 300 and the insulation tube 200 can clamp and fix the two ends of the heating tube 100 in the extension direction of the heating channel 101, so as to achieve the fixation of the position of the heating tube 100 in the extension direction of the heating channel 101 in the atomization assembly. Both the insulation tube 200 and the base 300 can be provided with mounting grooves facing the heating channel 101 in the extension direction of the heating channel 101. The inlet end and the outlet end of the heating tube 100 are respectively located in the corresponding mounting grooves. The side walls of the mounting grooves cooperate with the outer side walls of the heating tube 100 to limit the fixation of the position of the heating tube 100 in the atomization assembly in a plane perpendicular to the extension direction of the heating channel 101.

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

[0034] A connecting air cavity 330 is formed inside the base 300. The connecting air cavity 330 can be arranged in the radial direction of the heating tube 100. In the radial direction of the heating tube 100, the radial outer 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 port 2311, and then enter the heating channel 101 along the connecting air cavity 330 from the air inlet channel 250, mix with the aerosol generated after the aerosol product is heated, and be discharged along the opening 412 of the atomizing body 400. Since the air inlet 2311 and the connecting air cavity 330 are located at both ends of the air inlet channel 250 in the extension direction of the heating channel 101, 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 is usually facing upward, that is, the outlet end of the heating tube 100 is located on the upper side of 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 ascends along the heating channel 101, and finally is discharged from the opening 412 of the atomizing body 400. The condensate in the heating channel 101 will enter the connecting air cavity 330 under the action of gravity, which can reduce the condensate backflowing along the air inlet channel 250, thereby reducing the probability of condensate leaking from the air inlet 2311.

[0035] In some embodiments, the heat-insulating cylinder 200 and the base 300 can be an integrated structure to facilitate the assembly of the atomizing assembly. In order to facilitate the fixation of the position of the entire atomizing assembly in the atomizing body 400, in some embodiments, please refer to Figure 3 The insulation tube 200 can be provided with a limiting structure arranged in the extension direction of the heating channel 101. Correspondingly, a limiting matching structure that cooperates with the limiting structure needs to be provided on the atomizing body 400. The limiting structure cooperates with the limiting matching structure to determine the position of the atomizing assembly in the plane perpendicular to the extension direction of the heating channel 101, ensuring that the heating channel 101 in the atomizing assembly is coaxial with the opening 412 of the atomizing body 400.

[0036] Specifically, in one embodiment, please refer to Figure 3 The limiting structure may include a limiting protrusion 211, and the upper limiting matching structure on the atomizer body 400 includes a limiting recess 411. The limiting protrusion 211 may be a convex column, and the limiting recess 411 may be a groove. The convex column and the groove cooperate to achieve the assembly of the atomizer assembly and the atomizer body 400, which helps to fix the position of the atomizer assembly in the atomizer body 400 in a plane perpendicular to the extension direction of the heating channel 101. Of course, if the convex column is set on the atomizer body 400, the groove can also be set on the insulation cylinder 200.

[0037] In one embodiment, please refer to Figure 2, one of the limiting structure and the limiting matching structure can also be set as a hook 421, and the other is a slot or through hole 2211 that matches 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 insulation tube 200. The notch of the slot is set in the extension direction of the heating channel 101 toward the opening 412 of the atomizing body 400 or toward the air inlet 2311 of the atomizing assembly. The hook 421 is snap-fitted with the slot, and the position of the hook 421 is limited by the side wall of the slot, or the through hole 2211 is arranged in the extension direction of the heating channel 101, the hook 421 passes through the through hole 2211 and is snap-fitted 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 outer protrusion 231 provided on the insulation tube 200 can also serve as a limiting structure to cooperate with the through hole 413 on the atomizing body 400 to ensure that the position of the atomizing assembly is fixed in the atomizing body 400.

[0039] In other embodiments, a positioning ring may be provided at the opening 412 of the atomizing body 400 so as to be plugged into the first end opening of the thermal insulation tube 200 to achieve coaxiality between the heating channel 101 and the opening 412 of the atomizing body 400 .

[0040] In some embodiments, there are multiple limiting structures on the insulation tube 200, such as two, three or more than four. The multiple limiting structures can be evenly spaced around the circumference of the heating tube 100 to improve the assembly accuracy and positioning accuracy of the atomization assembly in the atomization body 400.

[0041] Correspondingly, multiple protrusions 231 can also be set on the insulation tube 200, and the multiple protrusions 231 are evenly spaced around the circumference of the heating tube 100 to increase the number of air inlets 2311 in the atomization assembly to ensure uniform air intake in the air inlet channel 250 and the heating channel 101.

[0042] For some examples, please refer to Figure 2The insulation tube 200 can be set as a split structure. The insulation tube 200 includes an inner tube body 210, an outer tube body 220 and a first sealing member 230. The inner tube body 210 is located inside the outer tube body 220 in the radial direction of the heating tube 100. The inner tube body 210 and the outer tube body 220 are arranged coaxially. The inner tube body 210 and the outer tube body 220 can both be roughly cylindrical structures. The inner tube body 210 extends toward the heating tube 100 at the end of the opening 412 of the atomizing body 400 in its extension direction, so as to be clamped at both ends of the heating tube 100 with the base 300 in the extension direction of the heating channel 101. The inner tube body 210, the base 300 and the heating tube 100 enclose a heat-insulating cavity 340. The inner tube body 210 can be made of a high-temperature resistant plastic material, and the outer tube body 220 can be made of a metal material or a plastic material.

[0043] The first sealing member 230 is located at the first end of the heat-insulating cylinder 200 in the extending direction of the heating channel 101, and the first sealing member 230 is respectively sealed with the inner cylinder 210 and the outer cylinder 220. Figure 2 The first sealing member 230 has an annular structure and has a first inner ring portion 232 and a first outer ring portion 233. The first outer ring portion 233 is connected to the radial outer side of the first inner ring portion 232. The first inner ring portion 232 can be abutted against the end of the inner cylinder 210 in the extension direction of the heating channel 101 to achieve sealing cooperation with the inner cylinder 210. The first outer ring portion 233 extends toward the base 300 in the extension direction of the heating channel 101. The radial 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 radial outer side of the outer cylinder 220. The first outer ring portion 233 is sealed with the outer cylinder 220 through a plurality of annular protrusions.

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

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

[0046] For some examples, please refer to Figure 2The outer protrusion 231 on the insulation tube 200 can be set on the first sealing member 230. The first sealing member 230, the inner tube body 210 and the outer tube body 220 enclose an air intake cavity 240. The air intake cavity 240 can be an annular cavity or can also include a plurality of arc-shaped cavities arranged at intervals in the circumferential direction of the heating tube 100. The air inlet 2311 is connected to the air intake channel 250 through the air intake cavity 240.

[0047] In order to increase the air intake, in one embodiment, a radially penetrating hole can be provided on the first inner ring portion 232 to serve as a gas inlet. The airflow entering the atomizing body 400 from the opening 412 of the atomizing body 400 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 inlet channel 250 is located between the inner cylinder 210 and the outer cylinder 220. In one embodiment, the air inlet channel 250 may include an annular channel or may also include a plurality of arc channels arranged at intervals in the circumferential direction of the heating cylinder 100. When the air inlet channel 250 includes a plurality of arc channels, the number of arc channels is equal to or less than the number of arc cavities to ensure that each arc channel can be connected to the air inlet 2311 through the arc cavity.

[0049] In some embodiments, in order to ensure the shape of the arc channel, one of the inner cylinder 210 and the outer cylinder 220 is provided with a positioning protrusion 212, and the other is provided 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] Please refer to Figure 4 In one embodiment, a positioning protrusion 212 can be provided at the end of the inner cylinder 210, and the positioning protrusions 212 can be arranged in pairs. The two positioning protrusions 212 arranged in pairs 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 the processing and manufacturing of the inner cylinder 210. There are multiple pairs of positioning protrusions 212, such as two pairs, which are arranged in the radial direction of the heating cylinder 100, which helps to fix the position of the inner cylinder 210 in the outer cylinder 220; the positioning recess 222 is provided at the end of the outer cylinder 220, and the positioning protrusion 212 is connected to the positioning recess 222. Corresponding to the positioning recesses 222, a dovetail-shaped guide rib 223 is provided between the two positioning recesses 222 arranged in pairs, and 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 shaking of the inner cylinder 210 and the outer cylinder 220 in the radial direction of the heating cylinder 100. A convex rib 2231 can also be provided on the side of the dovetail-shaped guide rib 223, and the convex rib 2231 is pressed against the side of the positioning protrusion 212 in the circumferential direction of the heating cylinder 100 to limit the relative shaking 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 inlet passage 250 includes an annular passage. To increase the flow area of the air inlet passage 250, please refer to Figure 3 , arranged in the extension direction of the heating channel 101, the size of the positioning protrusion 212 is smaller than the size of the inner cylinder 210; the positioning protrusion 212 can be arranged in a plurality of intervals in the extension direction of the heating channel 101, and can also be arranged in the extension direction of the heating channel 101, and the sum of the sizes of the plurality of positioning protrusions 212 is smaller than the size of the inner cylinder 210, so that an annular channel can be formed between the inner cylinder 210 and the outer cylinder 220 where the positioning protrusion 212 and the positioning recess 222 are not arranged in the extension direction of the heating channel 101, so as to increase the flow cross-sectional area of the air intake channel 250 and ensure the flow rate of the air intake channel 250.

[0052] Of course, in other embodiments, the positioning protrusion 212 and the positioning recess 222 can also pass through the inner cylinder 210 and the outer cylinder 220 in the extension direction of the heating channel 101, so that the air intake channel 250 includes two arc-shaped channels arranged at intervals in the circumferential direction of the heating cylinder 100.

[0053] In one embodiment, the first sealing member 230 may further include a sealing ring. The inner cylinder 210 and the outer cylinder 220 are sealed together via the sealing ring.
