A steam generating device includes a flat casing and a heating device is received in the casing. The heating device includes flanges which are engaged with grooves in the casing so as to define a lower space and an upper space between the heating device and the inner periphery of the casing. A seal is clamped between the heating device and casing to prevent foreign objects entering the casing. The heating device includes a chamber which is in communication with a hole defined in the bottom of the casing. Water is introduced into the lower space and steamized by the heating device, the steam enters into the upper space via passages and enters into the camber and blasts out from the hole of the casing. The steam travels a long path in the casing and is heated sufficiently so as to increase the efficiency for generating the steam.
