DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1 for a winger bucket 100 in accordance with the present invention, the winger bucket 100 comprises a bucket body 10, having a top surface substantially in a form of an opening 11, and a bottom surface having a internal space 12 at a lateral side; a dewatering basket 20, having a plurality of dewatering holes disposed at the periphery and the dewatering basket 20 being disposed in opposition to the top of the internal space 12; a propelling unit 30, being installed in the internal space 12, for propelling the dewatering basket 20. In the preferred embodiment, the winger basket 100 further comprises a handle 13 for facilitating users to carry the winger bucket 100.
With reference to FIGS. 2 to 3B, the propelling unit 30 further comprises a base 31, having two supporting shafts 311 and forming a first hole 313 and a second hole 314, wherein the supporting shafts 311 disposed on both sides of the base 31, two axial holes 312 being formed in opposition on the top of the supporting shafts 311; a big gear wheel 32, wherein a linked bevel gear 321 disposed on the top of the big wheel 32, and the big gear wheel 32 positioned on the first hole 313 by an fixing axle 322; a pail pedal 33, having an axial tube 331 therein, the pail pedal 33 positioned on the axial hole 312 by a screw 332, and a positioning surface 333 stretched from a side of the pail pedal 33 toward the bottom; a circular arc gear wheel 34, fixed onto the positioning surface 333, wherein the circular arc gear wheel 34 meshed with the bevel gear 321; a return spring 35, disposed on the axial tube 312, wherein a first extremity 351 positioned on the supporting shaft 311 and the second extremity 352 positioned on the pail pedal 33; a rotating axle 36, the bottom 361 of the rotating axle 36 installed on the second hole 314 by an assisting element 363 and the top 362 of the rotating axle 36 connected with the dewatering basket 20, for rotating the dewatering basket 20 freely; a small gear wheel 37, installed in the middle of the rotating axle 36 nevertheless the motion of the small gear wheel 37 and the rotating axle 36 do not rotate synchronously, the small gear wheel 37 meshed with the big gear wheel 32 thus driven by the big gear wheel 32; and an unilateral bearing device 38, installed on the rotating axle under the small gear wheel 37, driven in one direction by the small gear wheel 37 thus rotating the rotating axle 36 and the dewatering basket 20 in the same direction. In the preferred embodiment, the propelling unit 30 further comprises a fixed element 323 installed under the bottom of the big gear wheel 32.
With reference to FIGS. 4 and 5 provide the enlarged views of a portion of the present invention. Users step onto the pail pedal 33 and force the on the circular gear wheel 34 thus rotates the bevel gear 321 in the R1 direction. At the same time, the big gear wheel rotates in the R1 direction. Then, the small gear wheel 37 meshes with and is driven by the big gear wheel 32 rotating in the R2 direction. The unilateral bearing device 38 then rotates in the R2 direction and also drives the rotating axle 36 rotating in the same direction.
After users stop to step onto the pail pedal 33, as shown in FIG. 5, based on the stretch of the return spring 35 and the counterforce, the circular gear wheel 34 goes back to the original place thus rotates the bevel gear 321 and the big gear wheel 32 in R3 direction. The small gear wheel 37 then rotates in the R4 direction, wherein the unilateral bearing device 38 still rotates in the same direction, the R2 direction thus the rotating axle 36 spins in the original direction, the R2 direction. In this way, the dewatering basket 20 always spins in the same direction.
With reference to FIG. 6 provides a schematic perspective view of combining a mop 40 with the present invention. When users put the mop 40 into the dewatering basket 20, the centrifugation of the rotating dewatering basket 20 helps to remove water from the mop 40.
By adjusting the length of the circular gear wheel makes the present invention in different sizes thus fits more needs.
In the wringer bucket of the present invention, the rotating axle allows the dewatering basket to rotate freely. The structure is simple, so that the winger bucket will not be worn out easily with using time.
In addition, the structure helps users to save the force while users step on the pail pedal thus the users' feel more satisfies while using the present invention.
Many changes and modifications in the above-described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
