The isolation structure comprises a motor housing 72, and after being connected with the lower shell 14, the dry-wet motor 71 is isolated from other parts, so that water or water vapor is prevented from entering the motor housing 72. Winder 10 is installed in winder installing support 101, and winder installing support 101 includes upper bracket and lower carriage, but lower carriage and motor dustcoat 72 integrated into one piece, and lower carriage detachable sets up in upper bracket department, and both form a comparatively sealed installation space, and winder installing support 101 sets up in the one end of motor dustcoat 72, and the impeller of motor is kept away from to this end, can ensure that winder 10 keeps away from water or steam.

The heating device 32, the first water pump 31, the second water pump 42, and the like are disposed above the motor housing 72. The second water pump 42 is different from the first water pump 31, and the liquid pressure at the water outlet of the first water pump 31 is larger than that at the water outlet of the second water pump 42 because the liquid pressure in the instant heating boiler is larger. A cleaning head 9 is in fluid communication with the suction conduit via a hose 8, the cleaning head 9 comprising a handle and a suction nozzle. The first nozzle 33 is disposed between the suction nozzle and the handle, and the second nozzle 41 is disposed between the handle and the first nozzle 33.

Referring to fig. 1 and 24, fig. 24 is a schematic structural view of the cleaning head. The cleaning head 9 is in fluid communication with the suction line 6 via a hose 8. The cleaning head 9 includes a handle 92, a housing extending forwardly of the handle 92, and defining an elongated suction nozzle 91 at a forward end thereof for increasing the suction of the nozzle 91 to draw water stains from the surface to be cleaned into the recovery tank 5. The housing further defines an installation space for accommodating a part of the supply line of the cleaning liquid supply system. Referring to the drawings, the position between the suction nozzle 91 and the handle 92 is provided with bristles 93 where the first nozzle 33 is disposed. The first nozzle 33 sprays steam or heated fluid in the bristle extending direction.

In order to maintain the convenience of use, a part of the first pipeline 3 and a part of the second pipeline 4 are both provided inside the hose 8. I.e. the conduits from the housing 1 to the cleaning head 9, are provided in the hose 8 so that the user is not exposed to the outside during use.

The side wall of the housing 1 is also provided with a hanger for placing the cleaning head 9.

While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
