During inhalation, external air enters from the air inlet 23 and is delivered to the heating element 40 through the air inlet channel 617; then, it passes through the heating element 40 and carries the aerosol generated by heating to be output from the aerosol output tube 111.

[0092] In an embodiment, the airflow channel is defined by a plurality of components. In an embodiment, the airflow channel substantially passes through the bracket 60 longitudinally.

[0093] according to Figures 3 to 9 As shown in , there is also arranged between the end cover 20 and the bracket 60:

[0094] The absorption element 70 is basically in the form of a sheet arranged perpendicular to the longitudinal direction of the atomizer 100; the absorption element 70 is porous, for example, made of porous fiber cotton or porous ceramics. The absorption element 70 is accommodated and retained in the end cap 20, and is arranged at intervals from the separation ridge 615 in the longitudinal direction, so as to receive and absorb the aerosol condensate that seeps out from the air inlet channel 617 of the separation ridge 615 to the distal end 120. The absorption element 70 is provided with a perforation 71, which is aligned with the air inlet 23 on the end cap 20, so that air can flow to the air inlet channel 617 through the perforation 71.

[0095] The outer surface of the absorption element 70 is also defined with at least one or more clamping grooves, so as to be used for clamping and fixing the absorption element 70 from the outside by the clamping structure arranged on the end cover 20 and / or the bracket 60 after assembly.

[0096] After assembly, the air cavity 66 is in air communication with the air inlet 23 and / or the air flow channel through the space between the absorbent element 70 and the dividing ridge 615 .

[0097] according to Figures 3 to 9 As shown in FIG. 1 , the outer surface of the bracket 60 is provided with

[0098] The first air groove 622 extending helically is arranged around the bracket 60; the first air groove 622 extending helically is arranged along the longitudinal extension of the bracket 60; the first air groove 622 extending helically is continuous;

[0099] The first dividing flange 621 is defined between adjacent spirals of the spirally extending first air groove 622; the first dividing flange 621 is also in the shape of a spirally extending shape arranged around the bracket 60, and the first dividing flange 621 is also continuous;

[0100] After assembly, the second sealing portion 82 of the sealing element 80 wraps around the first partition flange 621 and the first air groove 622 from the outside, thereby closing the first air groove 622 from the outside.

[0101] according to Figures 3 to 9 As shown in , the bracket 60 is also arranged with:

[0102] The communication hole 65 passes through the air cavity 66 to the first air groove 622, thereby connecting the first air groove 622 with the air cavity 66. Furthermore, the first air groove 622 is in air communication with the air flow channel through the communication hole 65 and the air cavity 66.

[0103] according to Figures 3 to 9 As shown in , the bracket 60 is also arranged with:

[0104] The ventilation channel 67 is formed on the outer surface of the bracket 60 and is close to or extends to the first end 610; the ventilation channel 67 connects the liquid storage chamber 112 with the first air groove 622, so as to balance the pressure in the liquid storage chamber 112. The ventilation channel 67 is arranged between the first air groove 622 and the first end 610. And, the ventilation channel 67 is arranged in the form of a capillary groove located on the outer surface of the bracket 60. In some embodiments, the width or depth of the ventilation channel 67 is about 0.3 to 2.0 mm in width and / or depth.

[0105] The ventilation channel 67 includes:

[0106] The first channel portion 671 and the second channel portion 672 are basically arranged in sequence in the circumferential direction of the bracket 60.

[0107] The first channel portion 671 is connected to the liquid storage chamber 112; the first channel portion 671 is designed or arranged to be a Tesla valve channel; the first channel portion 671 configured as a Tesla valve channel is advantageous in that it can minimize the leakage of the liquid matrix in the liquid storage chamber 112 from the first channel portion 671;

[0108] The second channel portion 672 is communicated with the first air groove 622 and is arranged to extend in a circuitous or bent manner in the longitudinal direction of the bracket 60 to further prevent the liquid matrix from leaking outward through the second channel portion 672 .

[0109] The second channel portion 672 of the ventilation channel 67 is connected to the communication hole 65 and / or the air cavity 66 through the spiral path provided by the first air groove 622. Figure 6 As shown by the middle arrow R5 , in use, the air in the air cavity 66 can flow to the ventilation channel 67 through the spiral path provided by the first air groove 622 .

[0110] When the negative pressure in the liquid storage chamber 112 exceeds a predetermined threshold, Figure 6 As shown by the middle arrow R3 , the air in the first air groove 622 passes through the second channel portion 672 and the first channel portion 671 of the ventilation channel 67 in sequence and enters the liquid storage chamber 112 , thereby alleviating the negative pressure in the liquid storage chamber 112 .

[0111] When the liquid storage chamber 112 is injected with an oversaturated liquid matrix during production or when the pressure in the liquid storage chamber 112 is greater than the external pressure during use, Figure 7 As shown, the liquid matrix in the liquid storage chamber 112 will flow outwards in sequence through the first channel portion 671 and the second channel portion 672 of the ventilation channel 67. Specifically, when the liquid matrix in the liquid storage chamber 112 flows into the first channel portion 671 of the Tesla valve channel, a plurality of tributaries R41 and tributaries R42 that merge in opposite directions are formed in the flow, thereby increasing the resistance of the liquid matrix to flow out through the first channel portion 671 on the one hand; and the second channel portion 672 provides a tortuous outflow path R43 for the liquid matrix in the longitudinal direction, which is beneficial for increasing the resistance of the liquid matrix to flow outwards.

[0112] Based on the asymmetric resistance characteristics of the Tesla valve channel, which is difficult to flow out and easy to flow in, it is more difficult for the liquid matrix to seep outward through the ventilation channel 67, and it is easier for the liquid matrix that flows outward to flow back to the liquid storage chamber 112 through the ventilation channel 67 when the internal and external pressures of the liquid storage chamber 112 change.

[0113] according to Figures 3 to 9 As shown in , the bracket 60 is also arranged with:

[0114] At least one or more second air grooves 624 extend circumferentially along the bracket 60; and multiple second air grooves 624 are arranged at intervals or non-continuously in the longitudinal direction; adjacent second air grooves 624 form air communication through the notches 625 on the second dividing flange 623 between them.

[0115] The second air groove 624 is arranged between the second channel portion 672 of the ventilation channel 67 and the first air groove 622, and the second channel portion 672 of the ventilation channel 67 is indirectly connected to the first air groove 622 through the second air groove 624. When the pressure in the liquid storage chamber 112 is greater than the external pressure, causing the liquid matrix to seep out of the ventilation channel 67, the second air groove 624 can be used to absorb or store the liquid matrix flowing out of the ventilation channel 67 to prevent the liquid matrix seeping out of the ventilation channel 67 from directly flowing into the spiral first air groove 622. Of course, the liquid matrix absorbed by the second air groove 624 can also flow back to the liquid storage chamber 112 via the ventilation channel 67 when the internal and external pressures of the liquid storage chamber 112 change.

[0116] according to Figure 6 and Figure 8 As shown, the spiral first air groove 622 is spaced apart from or avoided from the ventilation channel 67 in the longitudinal direction of the bracket 60. Also, at least one or more second air grooves 624 are not closed in the circumferential direction; in the longitudinal direction of the bracket 60, the ventilation channel 67 at least partially crosses the second air groove 624.

[0117] In some embodiments, according to Figure 6 and Figure 8 As shown, there are at least two ventilation channels 67 arranged on the outer surface of the bracket 60; the at least two ventilation channels 67 are arranged between the first end 610 and the second air groove 624 of the bracket 60. When the liquid matrix in the liquid storage chamber 112 flows outward through one of the ventilation channels 67, the other ventilation channel 67 provides a reflux path for the outflowing liquid matrix to flow back toward the liquid storage chamber 112.

[0118] In the embodiment, the ventilation channel 67 and / or the second air groove 624 are both wrapped and covered by the sealing element 80 from the outside.

[0119] Or in some other embodiments, the ventilation channel 67 and / or the first air groove 622 and / or the second air groove 624 may also be grooves formed or arranged on the inner surface of the sealing element 80. After assembly, the ventilation channel 67 and the like are formed between the bracket 60 and the sealing element 80.

[0120] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
