A structure of steam swab comprises a rod assemblage and a base assemblage. The rod assemblage comprises a handle, a first sleeve, a second sleeve, a third sleeve, and a water tank. With a fastener set at the end, the handle and the two ends of each of the first, the second, and the third sleeves can be easily assembled to the rod assemblage. The second sleeve comprises a tank fastener base and a tank fastener ring to fasten the water tank. The base assemblage comprises a triangular lid, a steam chamber body, and a base. The triangular lid comprises a pivot connector, which can pivotally connect to the rod assemblage. An appropriate concave is set in each angle of the triangular lid to fix with a spring and a clamp. The steam chamber body and a power control unit are set in the base, and the triangular lid covers on the base to assemble the base assemblage. The base assemblage connects to the rod assemblage via the pivot connector to assemble the steam swab.
