The resistance heating track is substantially in the form of a curved band structure extending in a circuitous manner.

In one embodiment provided in the present application, the structure of the atomizer 100 is optimized so that the rectangular porous body 21 is placed inside the cylindrical shell 12, and the liquid storage chamber 120 can accommodate a sufficient amount of liquid matrix. Compared with the arrangement of a cylindrical porous body inside the cylindrical shell 12, the atomization chamber of the porous body is easily blocked by condensed liquid. The columnar atomizer 100 is provided with a block-shaped porous body 21 , and a portion of the outer surface of the porous body 21 is configured as an atomization surface 211 , which can effectively reduce the problem of condensate accumulation on the atomization surface 211 .

The atomizer 100 further includes a sealing element 30 . The sealing element 30 is made of a flexible silicone material or a fiber material and is formed into a sleeve-shaped body. The sealing element 30 surrounds a portion of the liquid absorption surface 212 and the side surface 213 of the porous body 21 .

10 , in the embodiment of the present application, the spacing arrangement direction of the liquid storage chamber 120 and the air flow chamber 121 is defined as a first direction A, and the first direction A is perpendicular to the longitudinal direction C of the housing 12. The atomizer 100 also includes a second direction B, wherein the second direction B, the first direction A, and the longitudinal direction C of the housing 12 are perpendicular to each other.

2, 6 and 8, the porous body 21 is fixed in the inner cavity of the shell 12 along a direction perpendicular to the longitudinal direction of the shell 12. The length direction L of the porous body 21 is parallel to the second direction B. When the outer diameter of the atomizer 100 is small, the longer side of the porous body 21 with a larger size can be placed as close to the two side walls of the shell 12 as possible, which is conducive to placing the block-shaped porous body 21 into the inner cavity of the shell 12.

Furthermore, the liquid storage chamber 120 and the airflow chamber 121 are arranged at intervals along a direction perpendicular to the length direction of the porous body 21, which is conducive to staggering the airflow chamber 121 and the atomization surface 211 of the porous body 21, thereby reducing the accumulation of condensate on the atomization surface.

Therefore, the length of the porous body 21 plus the thickness of the outer wall of the sealing element 30 on both sides thereof is substantially the same as the inner diameter of the liquid reservoir sleeve 12. The sealing element 30 will be squeezed and deformed during installation, so the thickness of the two side walls of the sealing element 30 is relatively small, making the length of the porous body 21 very close to the inner diameter of the shell 12. When the inner diameter of the shell 12 is small, the block-shaped porous body 21 can also be fixed. In the inner cavity of the housing 12. For example, when the inner diameter of the housing 12 is 8.1 mm, the length of the porous body 21 is 6.8 mm.

When the porous body 21 is configured as an end face seal rather than a side face seal, the outer surface of the porous body 21 can be configured to directly contact the inner wall of the shell 12, and the length of the porous body 21 is configured to be substantially the same as the inner diameter of the shell 12.

In other optional examples, the porous body 21 may also be configured as an irregular cubic shape, for example, by providing grooves on the liquid absorption surface 212 .

Further, the inner diameter of the housing 12 can be set to 15 mm, 10 mm, 8 mm or 5 mm, or any range between the above values, or any value within 20. It should be noted that the inner diameter of the housing 12 mentioned in the present application is configured as the diameter of the housing 12.

Further, the ratio of the length of the porous body 21 to the inner diameter of the shell 12 is in the range of 0.6 to 0.9.

In some embodiments, the atomization surface 211 of the porous body 21 is offset from the projection surface of the airflow cavity 121 , and the condensate is mainly formed inside the airflow cavity 121 , so the condensate will not accumulate on the porous body 21 and will not affect the atomization performance of the ceramic core atomization assembly 20 .

A first partition wall 122 is disposed inside the housing 12 , and the first partition wall 122 is used to separate the liquid storage chamber 120 from the air flow chamber 121 .

The first partition wall 122 and the second partition wall 123 are perpendicular to each other, and the first partial partition wall 1221 and the second partial partition wall 1222 are respectively arranged on both sides of the second partition wall 123. The first partial partition wall 1221, the second partial partition wall 1222 and the second partition wall 123 enclose a receiving cavity for receiving the porous body 21.

As shown in Figures 2, 6 and 8, along the length direction of the porous body 21, the two outer walls of the sealing element 30 are in contact with the inner wall of the shell 10 respectively. As shown in Figures 3 and 7, along the thickness direction of the porous body 21, the other two outer walls of the sealing element 30 are in contact with the first partial partition wall 1221 and the second partial partition wall 1222 respectively.
