Steam cleaner

Abstract

A steam cleaner includes a water pump to supply water from a water tank to a heater, and the heater heats it up to become steam to be shot out of a base so as to be used for washing a floor. The steam cleaner also has a water volume button for controlling operating frequency of the water pump to change steam volume to be shot out, by handling of a switch button fixed on a handle to control start and close of washing and operating condition. The grip of the handle is pivotally connected to the base with no limited stages so that the handle can be inclined to one of numerous angles to suit to the height of a user for conveniently using the steam cleaner. And a support base is provided for the steam cleaner to rest thereon for storing away when not used.

         2 . The steam cleaner as claimed as  claim 1 , wherein said steel rod has a tube joint fixed around a lower end, said tube joint has a center hole provided with opposite ribs, a connect rod inserting in said center hole of said tube joint and having opposite grooves formed in the rod body to engage said ribs of said tube joint, said rod body having its lower end fitted with a projecting edge and an engage head extending from a bottom end of the projecting edge, a gap formed between said projection edge and said engage head; said switch having one side combined with a L-shaped slide plate, said slide plate having a combine hole at top and a stopper extending down from one side of said combine hole, said engage head of said connect rod passing through said combine hole of said slide plate to have its passing length limited by said projecting edge, said gap of said connect rod being equal to the thickness of said slide plate, said connect rod rotating with said steel rod to the same direction for the same angle until said engage head is blocked by the stopper, which means that the engage head is already positioned in place, said steel rod already firmly connected with said plastic rod, said switch button related with said switch for \mutual movement.  
     
     
         3 . The steam cleaner as claimed in  claim 1 , wherein said plastic rod has a pivot formed respectively on two opposite sides of a lower end, and said base body has two curved grooves formed two sides of said recess and an inverted U-shaped fixing member, said fixing member having a curved engage groove respectively formed at two sides to match with said engage grooves of said recess so as to be used as a pivot hole for said pivots of said plastic rod to fit therein so that said plastic rod is combined pivotally with said base body.  
     
     
         4 . The steam cleaner as claimed in  claim 1 , wherein said transmission unit consists of said motor, a spindle gear, two transmitting gears, two pinions, two connect gears and two rotating discs, said motor having a spindle fixed with said spindle gear, said spindle gear engaging a first one of said two transmitting gear, said first transmitting gear engaging a second of said two transmitting gear, said second transmitting gear having a shaft fixed with said two pinions, said two pinions respectively engaging said two connect gears, said connect gears having a shaft respectively connected with a shaft of said two rotating discs, said rotating discs indirectly rotated by said motor,  
     
     
         5 . The steam cleaner as claimed in  claim 1 , wherein a valve is used instead of said water pump for controlling water coming from said water tank to enter said heater for heated up to steam.  
     
     
         6 . The steam cleaner as claimed in  claim 5 , wherein heater has a metal block, a heating tube embedded in said metal block, and a tube route provided in the interior of said metal block, the water stored in said water tank flowing into said tube route of said heater if said valve is opened, the water in said tube route heated up by said heating tube to become steam to be shot out of the shoot holes of said steam guide tube.  
     
     
         7 . The steam cleaner as claimed in  claim 1 , wherein a support is further provided under said base, having the same shape and size as that of said base so that said steam cleaner may be placed on said support base when not used and may be stored away.  
     
     
         8 . The steam cleaner as claimed in  claim 1 , wherein said grip and said steel rod respectively have a wire hook for a cleaner cord to be wound around and between them.
