The invention relates to a mop wringer bucket, and more particularly to a wringer bucket with which the bundle of mop yarn can be both cleaned and dewatered.

2. Description of the Related Art

Mop is one of the cleaning tools used for cleaning a floor, and traditional wringer buckets are used for removing extra water from the mop, and the traditional wringer buckets generally squeeze fabrics of the mop to remove water on the mop fabrics. As disclosed in R.O.C. Pat. No. M338634, a wringer bucket 50 includes a casing 51, an installing portion 52, and a rotating unit 53, wherein the rotating unit 53 includes a retaining element, an axle, a transmission unit and a push rod unit, such that interactions between the aforementioned components drive a dewatering basket 54 in rotation to dewater the mop 60. However, the assembly of the wringer bucket 50 has its own basic drawbacks. That is, the wringer bucket 50 provides only a room 55 for cleaning the mop 60 in vertical direction.

In fact, the dirty mop 60 can't be really cleaned if it is only cleaned in the direction of Y−Y. In other words, the dirt attached to the mop yarn 61 can't be removed from the mop yarn 61 only in this way. Moreover, the effect to clean the mop yarn 61 with the conventional wringer bucket is limited.

Besides, the mop yarn 61 becomes dirtier due to its repeated contact with the dirt settled at the bottom of the conventional wringer bucket.

In addition, the handle of the conventional wringer bucket is placed at one side of the bucket, thereby occupying more space than the bucket. Therefore, it causes difficulties in storage, transportation, and packaging.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

First of all, referring to FIGS. 2 through 7, an embodiment of a mop wringer bucket in accordance with the invention includes a bucket 10, a dewatering basket 20, and a driving mechanism 30.

The bucket 10 includes an opening 11 at the top thereof. A cavity 12 is formed at the front side of the bottom of the bucket 10.

The dewatering basket 20 is installed within the bucket 10 above the cavity 12.

The driving mechanism 30 is positioned in the cavity 12 for driving the dewatering basket 20. The driving mechanism 30 includes a base 31, a toothed rack 32, a pedal 33, an arched rack 34, a primary bevel gear 35, a secondary bevel gear 36, and a pinion 38.

The base 31 includes two supports 311 at both sides thereof. A shaft hole 312 is formed at the top of the supports 311, respectively. Moreover, a first positioning hole 313 and a second positioning hole 314 are formed in the base 31. A guide slot 316 is defined by a plurality of confining pieces 315.

The toothed rack 32 is positioned on the base 31 and movable to and from within the guide slot 316. The toothed rack 32 includes at the front side thereof a first toothed portion 321 directed upwards and at the rear side thereof a second toothed portion 322 directed inwards at 90°. Besides, a return spring 323 is installed at the rear side of the toothed rack 32 for imparting a forward return force to the toothed rack 32.

The pedal 33 is provided with a bolt sleeve 331 at both sides of the front end thereof. Two cross bolts 332 fit into the bolt sleeves 331 in place. An extension member 333 is extended from one side of the pedal 33 toward its bottom. Meanwhile, an arched groove 334 is formed on the extension member 333.

The arched rack 34 is positioned at the internal rim of the extension member 333 and under the arched groove 334. The arched rack 34 includes a lower toothed portion 341 at the bottom side thereof and an upper toothed portion 342 at the bottom side thereof. The lower toothed portion 341 is engaged with the first toothed portion 321 of the toothed rack 32.

The primary bevel gear 35 is positioned parallel to the supports 311 and provided with an axial gear 351 adapted to engage with the upper toothed portion 342 at the external side of a shaft hole 352 of the primary bevel gear 35. A shaft 352 fitting into the shaft hole 352 is fixed on the supports 311 in place.

The secondary bevel gear 36 is secured by a long shaft 37 with its bottom portion fitting into the first positioning hole 313 of the base 31 such that the secondary bevel gear 36 is engaged with the primary bevel gear 35. The top of the long shaft 37 juts out of the cavity 12 and fits into a connection seat 21 at the bottom of the dewatering basket 20.

The pinion 38 is secured by a short shaft 39 with its bottom portion fitting into the second positioning hole 314 of the base 31. The top of the short shaft 39 juts out of the cavity 12 and fits into a connection seat 41 at the bottom of a cleaning plate 40 within the bucket 10 for imparting a rotary motion to the cleaning plate 40 in the bucket 10.

In, trampling the pedal 33, both the dewatering basket 20 and the cleaning plate 40 can be rotated by the arched rack 34, thereby achieving the cleaning and dewatering effects.

The action of the operation will be described as follows: In trampling the pedal 33, the pedal 33 rotates on the cross bolts 332 in the pedal bolt sleeves 331, thereby imparting a fan-shaped motion to the arched rack 34. At that time, the first toothed portion 321 of the toothed rack 32 will be driven by the lower toothed portion 341 in a linear and inward motion. At the same time, the second toothed portion 322 imparts a rotary motion to the pinion 38 and the short shaft 39, thereby driving the cleaning plate 40 at the internal bottom of the bucket 10 in rotation. As shown in FIG. 8, the mop 60 is placed on the top of the cleaning plate 40. The dirt attached to the mop yarn 61 will be removed under the stirring and kneading action for the cleaning purpose. Thereafter, as shown in FIG. 9, it is placed on the dewatering basket 20 for the dewatering purpose. At the same time, the axial gear 351 at the internal side of the primary bevel gear 35 is driven by the upper toothed portion 342, thereby imparting a rotary motion to the primary bevel gear 35. Meanwhile, the secondary bevel gear 36 is indirectly driven in rotation. Furthermore, the dewatering basket 20 at the top of the long shaft 37 will be rotated, thereby removing the mop yarn 61 under the influence of the centrifugal force.

The mop wringer bucket in accordance with the invention skillfully employs a driving mechanism 30 to impart a rotary motion to the cleaning plate 40 and the dewatering basket 20, thereby ensuring a practical use.

Another feature of the mop wringer bucket in accordance with the invention lies in that two pivot holes 13 are positioned at the front and rear ends of the opening of the bucket 10 such that projections 141 at the internal end of two symmetrical U-handles 14 fit into the pivot holes 13 to create a pivotal connection. Moreover, the U-handle 14 is provided with an extension portion 142 at the central and internal side thereof such that the U-handles 14 can be separately placed at both side rims of the opening when they horizontally lie down on the bucket 10. To the contrary, both of the U-handles 14 create a carrying handle when they are swiveled in a vertical position to contact with each other.

As shown in FIG. 10, the U-handles 14 are swiveled upward until they are in contact with each other when in use. To the contrary, they are lowered to be placed on the rim of the bucket 10 when not in use. In this way, less space will be occupied. Moreover, in cleaning the mop, the water within the bucket 10 is not easily escaped from the bucket 10, thereby fulfilling many functions.
