By embedding the first heating mesh 121 and the second heating mesh 122 of the planar structure in the pipe wall of the porous ceramic 11, the first heating mesh 121 and the second heating mesh 122 are positioned in the area of the upper plane 111a of the inner wall of the through hole 111, so that the first heating mesh 121 and the second heating mesh 122 are conformal with the shape of the upper plane 111a of the inner wall of the through hole 111, and the problem that the porous ceramic 11 and the heating mesh 12 deform during co-firing can be avoided; and the first and second heat generating mesh sheets 121 and 122 are provided, so that the first and second heat generating mesh sheets 121 and 122 may alternately generate heat when generating heat, so that carbon deposition on the heat generating mesh sheets 12 may be reduced to avoid clogging of the porous ceramic 11.

Further, one end of the first heat generating mesh 121 and one end of the second heat generating mesh 122 are connected to each other. So that heat transfer can be performed between the first heat generating mesh 121 and the second heat generating mesh 122, that is, one of the first heat generating mesh 121 and the second heat generating mesh 122 is used as a heat conductor when in operation, and the other is used as a heat conductor, so that heat on the porous ceramic 11 is uniformly distributed.

In this embodiment, the heat generating mesh 12 includes a first electrode lead 123, a second electrode lead 124 and a third electrode lead 125, the first electrode lead 123 is located at one end of the first heat generating mesh 121 far away from the second heat generating mesh 122, the second electrode lead 124 is located between the first heat generating mesh 121 and the second heat generating mesh 122, the first heat generating mesh 121 and the second heat generating mesh 122 share the second electrode lead 124, and the third electrode lead 125 is located at one end of the second heat generating mesh 122 far away from the first heat generating mesh 121.

As shown in fig. 6 and 7, the atomizer provided in the second embodiment of the present utility model is substantially the same as that in the first embodiment (fig. 4 and 5), except that in the present embodiment:

the atomizer 10 further includes a heat conductive member 14, wherein the heat conductive member 14 is embedded in the wall of the porous ceramic 11 and is located in other areas than the heating mesh 12, i.e., the heat conductive member 14 is disposed in other areas of the wall of the porous ceramic 11 where the heating mesh 12 is not disposed, so that deformation caused by different thermal expansion coefficients of other areas of the porous ceramic 11 where the heating mesh 12 is not disposed and the areas where the heating mesh 12 is disposed when the porous ceramic 11 is sintered can be avoided.

Further, the heat conducting member 14 is in a grid-shaped arc structure, the inner wall of the through hole 111 is provided with an arc surface 111b, and the heat conducting member 14 is located in the area of the arc surface 111b, so that the shape of the heat conducting member 14 is conformal with the shape of the arc surface 111b on the inner wall of the through hole 111, and deformation of the sintered porous ceramic 11 is avoided.
