A direction from the atomization mounting seat 13 towards the liquid storage member mounting seat 14 is a second direction Y. The first direction X is substantially perpendicular to the second direction Y. An angle between the first direction X and the second direction Y may range from 70° to 110°. In an embodiment shown in FIG. 1, the first direction X and the second direction Y are perpendicular to each other, i.e. the angle between the first direction X and the second direction Y is 90°. In another embodiment not shown in the figures, the angle between the first direction X and the second direction Y may be 75°, 95°, etc. In another exemplary embodiment of the present disclosure, the atomization assembly 15 is disposed at the atomization mounting seat 13, and the liquid storage member 20 is detachably mounted at the liquid storage member mounting seat 14. The air outlet 17 is formed at a top of the housing 10. The atomization assembly 15 is disposed below the air outlet 17. Smoke generated by the atomization assembly 15 is output from the air outlet 17.

[0029] As shown in FIG. 1, the atomization mounting seat 13 has an outer surface protruding in the first direction X to form a liquid inlet passage 16.
