[0034] For some examples, please refer to Figure 3 and Figure 4The atomizing body also includes a sealing seat 4.

[0037] In another embodiment, the heat exchange core 32 is not provided in the heating element 3, and the heating element 34 can also be fixed on the outer wall surface of the heating tube 31. The heating element 34 can be a heating film.

The heating element 3 may include a needle-type heating element, which is mounted on the sealing seat 4 and extends into the first cylinder 1.

[0040] In the embodiment of the present application, in order to reduce the aerosol in the atomization channel 11 from flowing back to the air inlet 15, please refer to Figure 3 The path indicated by the arrow in the figure is the reflux path of the aerosol. A first partition 12 and a second partition 21 are arranged in the air inlet channel 25. The first partition 12 is arranged on the outer cylinder wall of the first cylinder 1, and the first partition 12 extends toward the second cylinder 2. The second partition 21 is arranged on the inner cylinder wall of the second cylinder 2, and the second partition 21 extends toward the first cylinder 1. The first partition 12 and the second partition 21 are arranged at intervals in the extension direction of the atomization channel 11.

[0041] In one embodiment, please refer to Figure 3 and Figure 4 The first baffle 12 can be cantilevered in the air inlet channel 25, and the first baffle 12 is spaced apart from the wall of the second cylinder 2. The first baffle 12 can be an annular plate continuously arranged in the circumferential direction of the atomization channel 11. A first channel 13 is formed between the first baffle 12 and the wall of the second cylinder 2, and the first channel 13 is an annular channel. In another embodiment, part of the first baffle 12 can be arranged to contact or seal with the wall of the second cylinder 2, so that the first channel 13 forms an arc-shaped channel. A plurality of first channels 13 can be provided, and the plurality of first channels 13 are spaced apart from each other in the circumferential direction of the atomization channel 11.

[0042] In one embodiment, the second baffle 21 can be cantilevered in the air inlet channel 25, and the second baffle 21 is arranged at intervals from the wall of the first cylinder 1. The second baffle 21 can be an annular plate continuously arranged in the circumferential direction of the atomization channel 11. A second channel 23 is formed between the second baffle 21 and the wall of the first cylinder 1, and the second channel 23 is an annular channel. In another embodiment, a part of the second baffle 21 can be arranged to contact or seal with the wall of the first cylinder 1, so that the second channel 23 forms an arc channel. A plurality of second channels 23 can be provided, and the plurality of second channels 23 are arranged at intervals in the circumferential direction of the atomization channel 11.

[0043] In an embodiment where both the first channel 13 and the second channel 23 are annular channels, the first channel 13 and the second channel 23 may be staggered in the radial direction of the atomization channel 11, so that when the reflux aerosol passes through the first channel 13 and the second channel 23, the reflux aerosol can be deflected in the radial direction of the atomization channel 11 under the blocking effect of the first partition 12 and the second partition 21, thereby reducing the rate and reflux amount of the reflux aerosol by deflecting in the radial direction.

[0044] In the embodiment where both the first channel 13 and the second channel 23 are arc-shaped channels, it is also possible to set only the first channel 13 and the second channel 23 to be staggered in the circumferential direction of the atomizing channel 11, so that when the refluxed aerosol passes through the first channel 13 and the second channel 23, under the blocking effect of the first partition 12 and the second partition 21, the refluxed aerosol can be deflected in the circumferential direction of the atomizing channel 11, so that the rate and amount of refluxed aerosol can be reduced by the circumferential deflection. Of course, in other embodiments, it is also possible to set the first channel 13 and the second channel 23 to be staggered in the circumferential direction of the atomizing channel 11, and it is also possible to set them to be staggered in the radial direction, so that the refluxed aerosol can be deflected in the radial and circumferential direction of the atomizing channel 11 in the air inlet channel 25 under the blocking effect of the first partition 12 and the second partition 21, and the rate and amount of refluxed aerosol can be reduced by the circumferential and radial deflections at the same time. The reduction in the reflux rate and the reflux amount of the reflux aerosol helps to ensure that the air inlet channel 25 and the air inlet 15 are clean, and can reduce the impact of the reflux aerosol on the user's experience.

[0045] In one embodiment, in order to further reduce the rate and reflux amount of the reflux aerosol, a plurality of first baffles 12 and second baffles 21 may be provided, wherein the plurality of first baffles 12 are arranged at intervals in the extension direction of the atomization channel 11, and the plurality of second baffles 21 are arranged at intervals in the extension direction of the atomization channel 11, and the first baffles 12 and the second baffles 21 are arranged alternately in the extension direction of the atomization channel 11. In this way, when the reflux aerosol passes through the air inlet channel 25, under the blocking effect of the plurality of first baffles 12 and the plurality of second baffles 21, the reflux aerosol can be deflected multiple times in the radial direction and / or circumferential direction of the atomization channel 11, thereby further reducing the influence of the reflux aerosol on the user experience.

[0046] Of course, in other embodiments, if only two first partitions 12 are provided and only one second partition 21 is provided, or two second partitions 21 are provided and only one first partition 12 is provided, or both the first partition 12 and the second partition 21 are provided.

[0047] In one embodiment, please refer to Figure 2 and Figure 6 The air inlet 15 is arranged on the cylinder wall of the first cylinder 1, and there are multiple air inlet 15. The multiple air inlet 15 are arranged at intervals in the circumferential direction of the atomizing channel 11. The first partition 12 is an annular plate. The first cylinder 1 also has a baffle 14 connected to the first partition 12. The baffle 14 is arranged in the extending direction of the atomizing channel 11. The baffle 14 is perpendicular to the first partition 12. Multiple baffles 14 can be provided. Baffles 14 are provided between two adjacent air inlets 15 arranged in the circumferential direction of the atomizing channel 11. The baffle 14 can seal the first cylinder 1 and the second cylinder 2. After being matched, it contacts with the second cylinder 2, so that the multiple baffles 14 isolate the two adjacent air inlets 15 in the circumferential direction of the atomization channel 11, so as to avoid the aerosol cross-flow between the two adjacent air inlets 15. The baffle 14 can make the reflux aerosol bend in the circumferential direction of the atomization channel 11, which can also reduce the reflux rate of the reflux aerosol, reduce the amount of reflux aerosol overflowing from the air inlet 15, and help to reduce the condensed aerosol gathered at the air inlet 15, thereby helping to ensure the clean appearance of the atomization component 10, and then ensure the user's experience.

[0048] Of course, in other embodiments, if the baffle 14 is not provided, the reflux rate and reflux amount of the reflux aerosol can be reduced only by deflecting the flow between the first channel 13 and the second channel 23 .

[0049] In one embodiment, please refer to Figure 3 and Figure 4The support portion 24 arranged on the second cylinder 2 divides the air inlet channel 25 into a first air inlet chamber 251 and a second air inlet chamber 252. The first air inlet chamber 251 is connected to the air inlet port 15. A connecting hole 242 is provided on the support portion 24 to connect the first air inlet chamber 251 with the second air inlet chamber 252. The first air inlet chamber 251 connects the air inlet port 15 and the second air inlet chamber 252. The first partition plate 12 and the second partition plate 21 are both arranged in the first air inlet chamber 251.

[0050] The supporting portion 24 includes a connecting section 241 and a supporting section 243. The connecting section 241 extends from the wall of the second barrel 2 toward the atomizing channel 11 or toward the first barrel 1. The supporting section 243 is connected to the end of the connecting section 241. The supporting section 243 extends in the extension direction of the atomizing channel 11 and away from the air inlet 15. The end of the supporting section 243 has a hooking structure. The heating barrel 31 has an outer flange at its end in the extension direction facing the first barrel 1. The hooking structure and the outer flange support and cooperate in the extension direction of the atomizing channel 11 to achieve the installation and positioning of the heating barrel 31 in the second barrel 2.

[0051] The connecting hole 242 is disposed on the connecting section 241, and there are a plurality of connecting holes 242, and the plurality of connecting holes 242 are evenly spaced and arranged in the circumferential direction of the atomizing channel 11. In order to facilitate the processing and manufacturing of the second barrel 2, in one embodiment, please refer to Figures 3 to 5 A plurality of second baffles 21 are arranged, and the plurality of second baffles 21 are arranged at intervals in the circumferential direction of the atomization channel 11, and the outer contour shape size of the second baffle 21 is set to be the same as the outer contour shape size of the connecting hole 242, so that the second baffle 21 and the connecting section 241 are staggered in the circumferential direction of the atomization channel 11, and the connecting hole 242 and the gap 22 between two adjacent second baffles 21 arranged in the circumferential direction of the atomization channel 11 are staggered in the circumferential direction of the atomization channel 11, and the connecting hole 242 is also staggered in the radial direction of the atomization channel 11 with the second channel 23 between the second baffle 21 and the first cylinder 1, so that the reflux aerosol will be deflected in the circumferential direction and radial direction of the atomization channel 11 when passing through the connecting section 241 and the second baffle 21, thereby increasing the number of deflections of the reflux aerosol and further reducing the rate and reflux amount of the reflux aerosol.

[0052] Of course, in other embodiments, the second partition plate 21 can also be set as an annular partition plate, and only the connecting hole 242 and the second channel 23 are staggered in the radial direction of the atomizing channel 11, which can also reduce the rate and amount of the reflux aerosol to a certain extent. Of course, if the second channel 23 and the connecting hole 242 have an overlapping portion in the radial direction of the atomizing channel 11, this is also possible, and the rate and amount of the reflux aerosol can be reduced only by the deflection of the reflux aerosol between the first channel 13 and the second channel 23.

[0053] In another embodiment, a plurality of first baffles 12 may be provided, and the plurality of first baffles 12 may be spaced apart in the circumferential direction of the atomization channel 11, and the gaps between two adjacent first baffles 12 and the air inlet 15 may be staggered in the circumferential direction of the atomization channel 11, so that part of the reflux aerosol may be deflected in the circumferential direction of the atomization channel 11 when passing through the first baffle 12 and the air inlet 15, so as to increase the number of deflections of the reflux aerosol.

[0054] In one embodiment, the first partition 12 can be arranged to gradually move away from the air inlet 15 from the wall of the first cylinder 1 to the direction close to the second cylinder 2, and the second partition 21 can be arranged to gradually move away from the air inlet 15 from the wall of the second cylinder 2 to the direction close to the first cylinder 1, so that the first partition 12 and the second partition 21 can both form conical partitions, and the side of the first partition 12 facing the air inlet 15 and the side of the second partition 21 facing the air inlet 15 can guide the intake airflow to increase the flow rate of the intake airflow; and the structure of arranging the first partition 12 and the second partition 21 obliquely can also make the reflux aerosol have a deflection in the axial direction of the atomization channel 11 to further reduce the rate and reflux amount of the reflux aerosol.
