When the atomizer 1 is assembled, the following steps may be employed:

(1) firstly, the seal sleeve 13 is sleeved on the atomization component 12;

(2) plugging the combined assembly of the gland 13 and the atomizing assembly 12 into the nest 142 of the upper housing 14;

(3) then, the upper seat body 14 is covered on the lower seat body 11, and the hook 148 of the atomizing assembly of the upper seat body 14 is buckled on the

clamping parts

1122 and 1132 of the lower seat body 11, so that the buckling connection between the upper seat body 14 and the lower seat body 11 is realized; meanwhile, the electrode lead of the atomizing assembly 12 is electrically connected with the electrode post 1114 on the lower seat 11;

(4) then the sleeve body 15 is sleeved on the upper seat body 14 to complete the assembly of the atomizing unit 10;

Thus, the air flow path in the atomizer 1 is as indicated by the arrows in fig. 7: air first enters the first air inlet passage through the second air inlet holes 2120 and the first air inlet holes 157, and then enters the atomizing chamber 110 through the through holes 1120 to be mixed with the aerosol. The aerosol air mixture then enters the first outlet channel through the through holes 1130 and then enters the second inlet channel 143. Then enters the annular upper seat body connecting channel and then enters the second air outlet channel 1466. And finally into the air flow duct 22 and finally out of the atomiser 1 via the air outlet 210. The tobacco liquid in the liquid storage cavity 23 sequentially passes through the liquid inlet hole 155 of the sleeve body 15 and the liquid channel 144 of the upper seat body 14, enters the groove 120 of the atomizing assembly 12, and contacts with the liquid absorbing surface, so that the liquid is guided.

In some embodiments, the second air inlet hole 2120 is located higher than the atomizing chamber 110, which can better prevent the leakage smoke from flowing out of the second air inlet hole 2120 under normal use condition. The bottom of the whole airflow channel of the atomizer 1 is substantially U-shaped, and the airflow direction at the position of the atomizing cavity 110 is parallel to the atomizing surface 1211 of the atomizing assembly 12, so that the smoke atomized by the atomizing surface 1211 is more easily carried away.

The porous ceramic body 121 is substantially bowl-shaped, and on the one hand, the overall height is high enough to facilitate the installation of the atomizing assembly 12 and the arrangement of the sealing sleeve 115; on the other hand, the distance from the liquid suction surface to the atomization surface 1211 is ensured to be close enough to ensure the atomization effect when the installation is convenient.

The inner surfaces of the grooves 1210 form the wicking surface of the porous ceramic body 121 and the grooves 1210 may increase the wicking area facilitating transport of the aerosol-generating substrate. The central portion 1212 of the porous ceramic body 121 is recessed towards the first surface 1211 to form an atomizing surface 1213 having an arcuate cross-section for receiving the heating element 122 for heating and atomizing the aerosol-generating substrate. It is to be understood that the porous ceramic body 121 is not limited to a rectangular parallelepiped shape, and may have other suitable shapes such as a cylindrical shape.

The porous ceramic body 121 may further include a pair of retaining walls 1214, wherein the retaining walls 1214 are respectively disposed on two opposite long sides of the atomizing surface 1213 to further block the heating element 122 and prevent the heating element 122 from tilting during the molding process of the atomizing assembly 12.

The heat generating element 122 may be formed integrally by pressing or the like using a metal heat generating sheet in some embodiments, and may include a first conductive portion 1221 having a flat plate shape, a second conductive portion 1223 having a flat plate shape, and an arc-shaped plate-shaped heat generating portion 1222 located between the first conductive portion 1221 and the second conductive portion 1223, where the arc-shaped plate-shaped heat generating portion 1222 is partially or completely embedded on the atomizing surface 1213 of the porous ceramic body 121, so as to compress the heat generating element when the porous ceramic body shrinks during the sintering process, and prevent the heat generating portion 1222 from tilting. Preferably, the heat generating portion 1222 is hollowed out in an S-shape to improve distribution of convenient thermal resistance.

The heat generating element 122 may include a pair of first fixing parts 1224 and a pair of second fixing parts 1225 in some embodiments; the pair of first fixing parts 1224 are sheet-shaped and are respectively vertically disposed on two opposite sides of the first conductive part 1221; the pair of second fixing portions 1225 are sheet-shaped and vertically disposed on two opposite sides of the second conductive portion 1222, respectively.
