STEAM FLOOR SCRUBBER

WIPO Patent Application WO/2017/084609

A1

A steam floor scrubber, comprising a scrubber body (100), a rotating shaft joint assembly (200) and a steam nozzle assembly (300) disposed on the scrubber body (100), the rotating shaft joint assembly (200) comprising a rotating shaft portion (205), and the scrubber body (100) being capable of flipped up or down by rotating about the rotating shaft portion (205); the steam nozzle assembly (300) mainly comprising a base (310), and nozzles (317) formed inside of the base (310) and facing the top and bottom sides of the scrubber body (100) respectively, each nozzle (317) being provided with a flexible switch, such that only the nozzles (317) on the side of the scrubber body (100) that faces the floor blow out steam during operations. By means of the steam nozzles having different operating states, and by virtue of steam pressure, weight of a steel ball (314) and compression spring force of a steel ball spring (315), the direction of flow of the steam may be altered, and the steam may be isolated, such that, when one side is in use, steam leakage from the other side is non-existent or negligible, thereby improving the efficiency of cleaning and at the same time conserving energy.
