Description:

FIELD OF THE INVENTION

The present invention relates to a mop dewatering device, in particular to a mop dewatering device with effort-saving and good dewatering effects.

BACKGROUND OF THE INVENTION

A wet mop can be divided into a sponge mop and a brush mop according to the type of its mop head. A piece of sponge is installed at the sponge mop head and can be squeezed to remove water from the mop to facilitate the mop dewatering process. However, the sponge generally comes with a limited range of expansion, and thus it is more difficult for users to mop dead corners of a floor. As to the brush mop head made of rags, cotton, or any other water absorbent material, the brush can be deformed or expanded to mop and clean dead corners, but the brush mop head is more difficult to dewater.

A traditional brush mop head requires users to squeeze water by hands, not only involving hard labor, but also causing a sanitary issue. Therefore, related manufacturers developed a mop dehydrator with a plastic basket, such that the brush mop head can be placed in the plastic basket, and users can squeeze the brush by turning the brush mop head. However, the squeezing effect of the traditional brush mop is poor, and the brush still contains lots of water after the squeezes. Furthermore, the plastic basket is installed at the rim of a bucket and users often turn over the whole bucket of water by applying non-uniform or excessively large forces during the process of squeezing the brush mop head. Obviously, the traditional mop heads require improvements.

In view of the aforementioned shortcomings of the conventional manufacturing machine, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a mop dewatering device with a design capable of achieving the effort-saving and good dewatering effects.

SUMMARY OF THE INVENTION

Therefore, it is a primary objective of the present invention to provide a mop dewatering device to achieve the effort-saving and good dewatering effects.

To achieve the foregoing objective, the present invention discloses a mop dewatering device, comprising: a first space, a second space interconnected with the first space, a dewatering drum and a dewatering control unit installed in the first space, and the dewatering drum including a plurality of drainage slots for draining water out from the first space and the second space; characterized in that the dewatering control unit comprises: a base; a pedal; a transmission base, disposed on the base, for producing a displacement when the pedal is operated and moved, and resuming the pedal to its original position by an elastic element; a transmission element, installed on the transmission base; a first gear, coupled to the transmission element; a second gear, coupled to the first gear; a transmission shaft, having an end installed on the base, and another end fixed to the bottom of the dewatering drum; and a one-way rotating bearing, sheathed and installed at an end of the transmission shaft, and coupled to the second gear.

To make it easier for the examiner to understand the objects, characteristics and effects of this invention, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.

FIG. 2 is a cross-sectional view of the present invention;

FIG. 3 is a perspective view of an internal structure of the present invention;

FIG. 4 is a schematic view of an operation of the present invention; and

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

With reference to FIGS. 1 to 3 for an exploded view, a perspective view and a schematic view of an internal structure of a mop dewatering device in accordance with the present invention respectively, the mop dewatering device comprises a dewatering drum 13 and a dewatering control unit 14. The dewatering control unit 14 comprises a base 141, a pedal 142, a transmission base 143, a transmission element 144, a first gear 145, a second gear 146, a one-way rotating bearing 147, a transmission shaft 148 and an elastic element 149. The transmission base 143 is installed on the base 141, for producing a displacement when the pedal 142 is operated and moved, and resuming the pedal 142 to its original position by an elastic element 149. An end of the elastic element 149 is coupled to the transmission base 143, and another end is coupled to a convex surface 1411 disposed on the base 141, such that when the pedal 142 is pressed down to push the transmission base 143 forward to produce a displacement, the position of connecting the elastic element 149 with the convex surface 1411 remains unchanged, so that when the transmission base 143 is moved forward, the elastic element 149 will be extended as well. After the downward pressing force of the pedal 142 disappears, the elasticity of the elastic element 149 will pull the transmission base 143 back to its original position and push the pedal 142 back to its start position again. The transmission element 144 is installed on the transmission base 143 and coupled to the first gear 145, and the first gear 145 is coupled to the second gear 146. An end of the transmission shaft 148 is disposed on the base 141, and another end is fixed to the bottom of the dewatering drum 13. The one-way rotating bearing 147 is sheathed and installed at an end of the transmission shaft 148 and coupled to the second gear 146.

Since the rotating transmission shaft 148 drives the dewatering drum 13 to rotate together, and it is insufficient to use the base 141 to fix the transmission shaft 148 and the dewatering drum 13, therefore a fixing element 150 is sheathed onto the transmission shaft 148 for fixing the fixing element 150 to the bottom of the first space (not shown in the figure) to prevent the transmission shaft 148 from sliding sideway during its rotation, and enhance the structural stability. Since the fixing element 150 is sheathed onto the transmission shaft 148, therefore the rotation of the transmission shaft 148 will not be affected, and the fixing element 150 is a bearing.

With reference to FIGS. 4 and 5 for schematic views of the operation of the present invention, the mop dewatering device 10 of the invention comprises a first space (not shown in the figure), a second space 11 interconnected with the first space, a dewatering drum 13 and a dewatering control unit 14 installed in the first space, wherein the dewatering drum 13 includes a plurality of drainage slots 131 for draining water out from the first space (not shown in the figure) and the second space 11. If a user wants to dewater the mop 20, the user can put the mop 20 into the dewatering drum 13 and uses the dewatering control unit 14 to turn the dewatering drum 13 and drive the mop 20 to rotate, such that the rotation squeezes the mop 20 in the dewatering drum 13 to achieve the mop dewatering effect. The water separated from the mop 20 drains through the plurality of drainage slots 131 disposed at the periphery of the dewatering drum 13 and flows into the first space (not shown in the figure). Since the first space (not shown in the figure) is interconnected with the second space 11, the water can be discharged into the second space 11 for a temporary storage to increase the water storage of the mop dewatering device 10. If the user wants to dewater the mop, the user can put the mop 20 in the dewatering drum 13 and steps the user's foot on the pedal 142, such that the pedal 142 is pressed down to push the transmission base 143 to move forward and produce a displacement. The transmission element 144 installed on the transmission base 143 drives the first gear 145, the second gear 146, the one-way rotating bearing 147 and the transmission shaft 148 to rotate sequentially. When the transmission base 143 resumes its original position, the transmission element 144 drives the first gear 145 and the second gear 146 to rotate clockwise. Since the one-way rotating bearing 147 is rotated in a single direction and will not rotated in a reverse direction, therefore the transmission shaft 148 will not be rotated in a reverse direction. When the transmission shaft 148 is driven to rotate, the dewatering drum 13 is driven to rotate and squeeze the mop 20 rapidly.

If the user releases the pedal 142, the elastic element 149 will be extended to resume the pedal 142 and the transmission base 143 to their original positions, so that the user can step on the pedal 142 again and enhance the force of rotating and squeezing the mop 20. After the aforementioned procedure is repeated for several times, the mop 20 can be rotated and dewatered completely. Since the force applied by the user's foot is much larger than the force applied by the user's hand, the dewatering effect of the mop 20 is much better than the dewatering effect by squeezing the mop 20 by hands. The mop dewatering device 10 of the invention not only dewaters the mop efficiently, but also avoids getting the user's hands dirty.

When a user rinses a mop, the user usually has to go back to a place where water is available or carries a bucket of water to the working floor, but a bucket generally does not come with a dewatering design, and thus the user has to dry the mop by squeezing the mop by hands. In addition to the poor dewatering effect, the user's hands may also get dirty. If clean water is stored in the second space 11, the user can rinse the mop in the second space 11, and uses the aforementioned mop dewatering method to dewater the mop, and then the user can continue mopping without going back to the place where water is available, so as to enhance the mopping efficiency.

The mop dewatering device 10 of the invention further comprises a handle 12 for facilitating users to carry the mop dewatering device 10 to a place where water is available or carry the mop dewatering device 10 to a desired mopping floor.

In summation of the description above, the present invention provides a feasible design and complies with patent application requirements, and thus is duly filed for patent application.

While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
