MOP DEWATERING DEVICE
A mop dewatering device includes a first space, a second space interconnected with the first space, a dewatering drum and a dewatering control unit installed in the first space. The dewatering drum includes drainage slots for draining water out from the first and second spaces. The dewatering control unit includes 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. Thus, the invention can achieve the effort-saving and good dewatering effects.
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 INVENTIONA 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 INVENTIONTherefore, 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.
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
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
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.
