Abstract

A vapor generation device and a susceptor thereof are disclosed. The susceptor is in a blade shape extending in an axial direction of a cavity, and includes: a first part having a first size in a thickness direction, and a second part having a second size in the thickness direction, the second size being greater than the first size. An accommodation cavity extending in the axial direction is further arranged in the second part, and the accommodation cavity is configured to accommodate or encapsulate a temperature sensor that senses a temperature of the susceptor. The vapor generation device and the susceptor of this application encapsulates or accommodates the temperature sensor in the susceptor. Hence, a sensing part may be basically insulated from the impact of the magnetic field, and the susceptor and the temperature sensor may be integrated to increase stability of mounting and accuracy of temperature detecting.
