Mop wringer bucket

Abstract

A mop wringer bucket substantially comprising a bucket, a dewatering basket within the bucket, and a driving mechanism for driving the dewatering basket. The driving mechanism imparts a rotary motion to a cleaning plate at the bottom of the bucket such that the dirt attached to the mop yarn will be effectively removed under the stirring and kneading action of the cleaning plate. Thereafter, the mop yarn is placed in the dewatering basket of the same bucket, and the water absorbed by the mop yarn is removed by the centrifugal force, thereby enhancing the cleaning effect. In addition, the symmetrical U-handles specially designed at both sides of the bucket can be horizontally disposed on the rim of the bucket or swiveled to contact with each other to create one carrying handle, thereby achieving the space-saving effect and preventing the water from escaping from the bucket.

1 . A mop wringer bucket, comprising:
 a) a bucket having an opening at the top thereof, a cavity being formed at the front side of the bottom of the bucket;   b) a dewatering basket installed within the bucket above the cavity; and   c) a driving mechanism positioned in the cavity for driving the dewatering basket;   
       wherein the driving mechanism includes:
 i) a base having two supports at both side thereof, a shaft hole being formed at the top of the supports, respectively, a first positioning hole and a second positioning hole being formed in the base, a guide slot being defined by a plurality of confining pieces; 
 ii) a toothed rack positioned on the base and movable to and from within the guide slot, the toothed rack having at the front side thereof a first toothed portion directed upwards and at the rear side thereof a second toothed portion directed inwards at 90°, a return spring being installed at the rear side of the toothed rack for imparting a forward return force to the toothed rack; 
 iii) a pedal provided with a bolt sleeve at both sides of the front end thereof, two cross bolts fitting into the bolt sleeves in place, an extension member being extended from one side of the pedal toward its bottom, an arched groove being formed on the extension member; 
 iv) an arched rack positioned at the internal rim of the extension member and under the arched groove, the arched rack having a lower toothed portion at the bottom side thereof and an upper toothed portion at the bottom side thereof, the lower toothed portion being engaged with the first toothed portion of the toothed rack; 
 v) a primary bevel gear positioned parallel to the supports and provided with an axial gear adapted to engage with the upper toothed portion at the external side of a shaft hole of the primary bevel gear, a shaft fitting into the shaft hole being fixed on the supports in place; 
 vi) a secondary bevel gear is secured by a long shaft with its bottom portion fitting into the first positioning hole of the base such that the secondary bevel gear is engaged with the primary bevel gear, the top of the long shaft jutting out of the cavity and fitting into a connection seat at the bottom of the dewatering basket; and 
 vii) a pinion secured by a short shaft with its bottom portion fitting into the second positioning hole of the base, the top of the short shaft jutting out of the cavity and fitting into a connection seat at the bottom of a cleaning plate within the bucket for imparting a rotary motion to the cleaning plate in the bucket, 
 
       whereby, in trampling the pedal, both the dewatering basket and the cleaning plate can be rotated by the arched rack, thereby achieving the cleaning and dewatering effects. 
     
     
         2 . The mop wringer bucket as recited in  claim 1  wherein two pivot holes are positioned at the front and rear ends of the opening of the bucket such that projections at the internal end of two symmetrical U-handles fit into the pivot holes to create a pivotal connection, and wherein the U-handle is provided with an extension portion at the central and internal side thereof such that the U-handles can be separately placed at both side rims of the opening when they horizontally lie down on the bucket, and wherein both of the U-handles create a carrying handle when they are swiveled in a vertical position to contact with each other. 
     
     
         3 . The mop wringer bucket as recited in  claim 1  wherein the surface of the cleaning plate is provided with a plurality of radial ribs.
