A sun gear 33 corresponding to the driving unit 20 is fixed, and a one-way bearing 330 is disposed between the sun gear 33 and the rotating shaft 31, and the bottom of the rotating shaft 31 is pivotally mounted on the driving unit 20 through the self-lubricating bushing 34.

As shown in FIG. 4, FIG. 5 and FIG. 6, the driving unit 20 includes a base 21, a brake member 23, and a slide. The movable member 25 and the planetary acceleration group 26 are locked to the bottom of the installation space 13 of the barrel 10, and the base 21 is formed with a shaft seat for receiving the self-lubricating sleeve 34 at the bottom end corresponding to the rotating shaft 31. 210, and the two sides of the base 21 respectively have a rising relative support frame 22, the two support frames 22 are formed with an upright card slot 220 at the inner side of the opposite wall surface, and the brake member 23 utilizes the shafts on both sides. 233 is pivotally disposed between the top ends of the two support frames 22, and the brake member 23 has a pedal portion 231 for stepping outward and a pushing portion 232 for pushing the slider 25 inwardly, and the support frame 22 and the brake member 23 are interposed between the shafts The rod 233 is sleeved with a torsion spring 234, so that the brake member 23 can generate an upwardly resetting spring preload after being stepped down, and the bottom end of the braking member 23 is different from the pedal portion 231. 235.

Furthermore, the base 21 has two inverted L-shaped guide vanes 24 opposite to the sliding space 240, and the sliding member 25 linearly slides in the sliding space 240, and the opposite sides of the sliding member 25 are formed with opposite limits on the guide rails. a fin 250 under the flap 24, and the slider 25 is formed with a rack portion 251 on a side edge of the rotating shaft 31 corresponding to the water unit 30, and the slider 25 is formed with a pivot frame corresponding to one end of the stopper 23 The slot 252, the pivot frame slot 252 is pivotable to the abutting portion 232 of the brake member 23, and the brake member 23 is coupled to the slider 25.

The planetary acceleration group 26 is pivotally provided with a wheel body 27 on the rotating shaft 31. The top surface of the wheel body 27 is formed with three-lobed arc-shaped limiting protrusions 275, and is formed between adjacent limiting protrusions 275. The wheeled space 276 is slightly rounded, so that the wheel body 27 can be respectively pivoted with the planetary gears 28 by using the respective rotating spaces 276, and the planetary gears 28 can simultaneously mesh with the sun gear 33 of the rotating shaft 31, and the wheel body The top surface of the inner tooth cover body 270 is formed with an inner tooth edge that can be engaged with the outer edge of each of the planetary gears 28, and the center of the top surface of the inner tooth cover body 270 has an upward extending direction. a protruding shaft portion 271, and a waterproof sleeve 272 is disposed between the protruding shaft portion 271 and the rotating shaft 31. Further, a peripheral edge of the inner tooth cover body 270 has a strip 274 corresponding to the slot 220 of the two side support brackets 22, so that the inner tooth cover The body 270 can be positioned and not rotated, and the lower portion of the wheel body 27 is formed with a smaller diameter rod portion 273 which meshes with the rack portion 251 of the slider 25 to cause the slider 25 to be displaced by the brake member 23. The brake member 23 can compress the torsion spring 234 to generate a return preload. Thereby, the group constitutes a mop dehydration with high acceleration rotation stability and improved operation convenience.

Through the above structural design, in the actual application, as shown in FIG. 4, FIG. 5 and FIG. 6, under normal conditions, the brake member 23 of the driving unit 20 is returned to the pre-stress by the torsion spring 234, so that The pedal portion 231 of the movable member 23 is tilted upward, and the common synchronous driving slider 25 is positioned at the front end of the base 21.

In operation, as shown in FIGS. 7 and 8, the user first places the mop set of the mop in the drain basket 35 of the drowning unit 30 of the tub 10, and then pedals the brake member of the drive unit 20 with one foot. 23 pedal portion 231, the brake member 23 pushing portion 232 can push the slider 25 to slide relative to the base 21 by the pivotal relationship of the pivot block 235 and the pivot frame groove 252, and the rack portion 251 of the slider 25 Engaging with the lower rod portion 273 of the wheel body 27 of the drive unit 20, the inner tooth cover 270 of the wheel body 27 can be rotated relative to the wheel body 27, and the wheel body 27 can pass through the planetary gear 28, the sun gear 33 and the one-way bearing 330. The drain basket 35 is driven indirectly by the shaft 31, and when the brake member 23 is acted upon by the torsion spring 234, the slider 25 is simultaneously brought back and moved back, and since the slider 25 can rotate the wheel body 27 in the reverse direction, the sun gear is passed through the sun gear. The design of the one-way bearing 330 of 33 causes the sun gear 33 to idling between the rotating shaft 31 and does not cause the rotating shaft 31 of the drain basket 35 to rotate in the reverse direction, so that the drain basket 35 can only rotate in one direction.

Thus, after the brake member 23 is reciprocally stepped on, the rotational speed of the wheel body 27 can be gradually increased, and since the wheel body 27 can move the sun on the rotating shaft 31 through the large-diameter inner tooth cover body 270 and the two or more planetary gears 28 The gear 33 can increase the speed ratio thereof, so that the rotating shaft 31 can accelerate the rotation, thereby driving the drain basket 35 of the water sloshing unit 30 to rotate at a high speed, so that the moisture of the mop group placed inside the drain basket 35 can be extracted by centrifugal force. The purpose of dehydration is that the driving force mainly uses the planetary acceleration group 26, so the driving force is distributed on the periphery of the rotating shaft 31, and there is no one-sided stress phenomenon, which greatly improves the stability of the operation, and the speed is much higher than the existing products. Therefore, the dehydration efficiency can be improved, and the sloshing phenomenon during operation is small, and the problem that the component is loosened does not occur, so that the service life can be prolonged.
