FIELD OF THE INVENTION
The present invention relates to a mop bucket, and in particular to a mop bucket cleaning and squeezing a flat mop, and a cleaning tool set using the mop bucket.
DESCRIPTION OF THE PRIOR ART
In the prior art, there are three approaches for squeezing a flat mop. The first approach is by stepping on the pedal to squeeze a mop fabric on the flat mop. In this approach, a foot-operated squeezing device is provided on a mop bucket; the foot-operated squeezing device comprises a squeezing basket built-in the mop bucket and a pedal hinged to an upper portion of the mop bucket and arranged in opposite to the squeezing basket; and, the pedal and the squeezing basket form a squeezing space. During squeezing, the mop fabric on a mop plate of the flat mop should be detached firstly, the mop fabric is then placed into the squeezing space, and the squeezing space is shrunk by stepping on the pedal so as to squeeze water from the mop fabric. In this squeezing approach, a foot-operated squeezing device with a complicated structure needs to be designed, and the cost is thus relatively high; moreover, during squeezing, the mop fabric needs to be detached, and a pedaling operation needs to be performed by a foot, so that the operation is inconvenient.
The second approach is by centrifugal rotation. In this approach, a hand-operated rotary mop rod is used. During squeezing, two ends of a mop plate of a flat mop need to be bent and then placed into a squeezing water section in a mop bucket and then the mop rod is pressed down, so that the mop plate of the flat mop is centrifugally rotated for squeezing. In this squeezing approach, the mop plate of the flat mop needs to be designed as a bendable structure, the structure is complicated, and such a squeezing approach requires a hand-operated rotary mop rod so that the cost is relatively high.
The third approach is by pushing manually and squeezing. For example, Chinese Utility Model Patents CN201171658Y (Patent No.: ZL200720192814.5), CN203074606U (Patent No.: ZL201320019718.6), CN204146974U (Patent No.: ZL201420624020.1) and the like, disclosed a kind of flat mop, which comprises a mop rod, a flat mop plate movably connected onto the mop rod, a wiper disposed on the flat mop plate, and a squeezing mechanism disposed on the mop rod. The wiper on the flat mop plate is squeezed and cleaned by the relative movement and squeezing between the squeezing mechanism and the flat mop plate. This approach has the following disadvantages: during squeezing, it is necessary to hold the mop rod by one hand and the squeezing mechanism by the other hand to achieve the relative movement and squeezing between the squeezing mechanism and the flat mop plate by pushing or pulling the squeezing mechanism with a single hand. Therefore, the squeezing operation is very strenuous and this approach results in low practicability and low user experience.
At present, there is no mop bucket which is suitable for a flat mop and can achieve both functions of cleaning and squeezing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
To enable a further understanding of the present invention content of the invention herein, refer to the detailed description of the invention and the accompanying drawings below:
Embodiment 1 of the Mop Bucket of the Present Invention
FIG. 1-FIG. 11 show a first embodiment of the mop bucket for cleaning and squeezing a flat mop. The mop bucket comprises a bucket body 1 and two squeezing devices 7 disposed on the bucket body 1. The bucket body 1 is divided into two volumes, one volume defined as a squeezing water section 5 and the other volume defined as a cleaning section 6, which are separated with each other and respectively located at two different positions, the two squeezing devices 7 are respectively disposed at the squeezing water section 5 and the cleaning section 6. The mop bucket is used together with a flat mop 2; the flat mop 2 comprises a mop rod 3, a mop head 4 rotatably attached to the mop rod 3, and a wiper disposed on the mop head 4. As shown in FIG. 2, the wiper can be disposed on a front surface and/or a rear surface of the mop head 4. When the mop head 4 of the flat mop 2 is removably inserted into one of squeezing device 7, the squeezing device 7 presses against the wiper on the mop head 4 and scrapes the wiper on the mop head 4 repetitively, so as to clean the wiper or make the wiper be squeezed.
The detail structure of the squeezing device 7 can be anyone of the following six embodiments.
Embodiment 1 of the Squeezing Device of the Present Invention
FIG. 3 shows a first embodiment of the squeezing device, the squeezing device 7 comprises a frame 9 and a squeezer 11; the frame 9 has a squeezing port 10 for receiving the mop head 4. The squeezer 11 is disposed adjacent to the squeezing port 10 and exposed out of the squeezing port 10. In this embodiment, the squeezer 11 is a squeezing roller which is fixed on the squeezing port 10. That is, the width of the squeezing port 10 remains unchanged. After the mop head 4 is inserted into the squeezing port 10, the squeezer 11 can press the wiper on the mop head 4 to scrape the wiper.
Embodiment 2 of the Squeezing Device of the Present Invention
FIG. 4 shows Embodiment 2 of the squeezing device, the difference between the squeezing device of Embodiment 2 and of Embodiment 1 is that, the squeezer 11 is a squeezing strip movably connected to the squeezing port 10. That is, during cleaning and squeezing, the width of the squeezing port 10 can be changed by moving the squeezing strip, so that the wiper on the mop head 4 is scraped. Specifically, the squeezing strip is movably connected to the squeezing port 10 of the frame 9 via an elastic device which is a spring 14. That is, the squeezing strip is connected to the frame 9 via the spring 14, so that the squeezer 11 is somewhat elastic. Meanwhile, a squeezing strip 12 and a brush column 13 are disposed on the squeezing strip. The cross-section of the squeezing strip 12 is approximately arch-shaped. The squeezing strip 12 plays a primary squeezing role, and the brush column 13 plays an auxiliary squeezing role. During squeezing, the mop head 4 can be more smoothly inserted into the squeezing port 10 and the wiper on the mop head 4 can be squeezed by the squeezing strip 12 and the brush column 13, so that the wiper on the mop head 4 can be better cleaned and wrung.
Embodiment 3 of the Squeezing Device of the Present Invention
FIG. 5 shows Embodiment 3 of the squeezing device, the difference between the squeezing device of Embodiment 3 and of Embodiment 1 is that, the squeezer 11 is a squeezing strip fixed on the frame 9. Specifically, a squeezing strip 12 and a brush column 13 are disposed on the squeezing strip, and the cross-section of the squeezing strip 12 is approximately U-shaped.
Embodiment 4 of the Squeezing Device of the Present Invention
FIG. 6 shows Embodiment 4 of the squeezing device, the difference between the squeezing device of Embodiment 4 and of Embodiment 1 is that, the squeezer 11 is a squeezing strip disposed in the squeezing port 10. Specifically, a squeezing strip 12 is disposed on the squeezing strip, and the squeezing strip 12 is a squeezing ridge.
Embodiment 5 of the Squeezing Device of the Present Invention
FIG. 7 shows Embodiment 5 of the squeezing device, the difference between the squeezing device of Embodiment 5 and of Embodiment 4 is that, a brush column 13 is disposed on the squeezing strip.
Embodiment 6 of the Squeezing Device of the Present Invention
FIG. 8 shows Embodiment 6 of the squeezing device, the difference between the squeezing device of Embodiment 6 and of Embodiment 2 is the movably mounting manner of the squeezer. That is, the frame 9 has an inclined groove, and the squeezer 11 is movably positioned in the groove and can move along the inclined groove, so that the way of changing the width of the squeezing port is different. Specifically, the squeezer 11 is a squeezing strip; protruded sliders 15 are disposed at two ends of the squeezing strip; and correspondingly, an oblique slide rail 16 matched with the sliders 15 are disposed on the frame 9; the sliders 15 are disposed in the oblique slide rail 16 and can slide within the oblique slide rail 16 so as to move the squeezer 11, so that the width of the squeezing port 10 can be changed during cleaning and squeezing of the mop head 4.
In this embodiment, a baffle 8 is disposed inside the bucket body 1 so that the cleaning section 6 and the squeezing water section 5 are physically separated with each other in the bucket body 1. At least one squeezing device 7 is disposed at the cleaning section 6, and at least one squeezing device 7 is disposed at the squeezing water section 5. As shown in FIG. 1, one squeezing device 7 is disposed at each of the cleaning section 6 and the squeezing water section 5, wherein the squeezing device 7 within the cleaning section 6 is used for squeezing and cleaning the wiper on the mop head 4 and the squeezing device 7 within the squeezing water section 5 is used for squeezing and squeezing the wiper on the mop head 4.
As shown in FIG. 9, two squeezing devices 7 of Embodiment 6 are disposed at the cleaning section 6 and the squeezing water section 5, and the two squeezing devices 7 are arranged in parallel and located on two sides of the squeezing port 10, respectively, so that the cleaning and squeezing effects are enhanced.
In order to prevent the mop head 4 of the flat mop 2 from directly coming into contact with the bottom of the mop bucket, a buffer for the flat mop 2 is disposed within the squeezing water section 5 and/or the cleaning section 6 of the bucket body 1. As shown in FIG. 10, the buffer is a spring-loaded device disposed on a bottom of the bucket body 1; the spring-loaded device comprises an ejected spring 17 with a lower end and an upper end and a rebound carrier 18; a fixed sleeve 19 is disposed on the bottom of the cleaning section 6 and the squeezing water section 5, and the rebound carrier 18 is sheathed within the fixed sleeve 19; the bottom of the ejected spring 17 is fixed relative to the bucket body 1, while the top of the ejected spring 17 presses against the rebound carrier. During cleaning and squeezing, the mop head 4 is ejected onto the rebound carrier 18 so that the mop head is cushioned by the elasticity of the ejected spring 17.
During squeezing within the squeezing water section 5, the wrung water is retained within the squeezing water section 5, so that a certain water level is formed within the squeezing water section 5. In order to prevent the mop head 4 from coming into contact with the wrung water during squeezing to influence the squeezing effect, as shown in FIG. 11, an enclosure frame 25 is disposed on the bottom of the squeezing water section 5, and the enclosure frame 25 further comprises a upper end surface and a guide port 25a inclined downward on the upper end surface. In this way, during squeezing, the mop head 4 is pressed down and inserted into the enclosure frame 25; a very large amount of the wrung water falls outside the enclosure frame 25, with only a very small amount of water falling into the enclosure frame 25; and the wiper on the mop head 4 absorb this very small amount of water again. In this way, after multiple repetitions of squeezing, the wiper is wrung better.
In practical applications, the mop head 4 is rotated to a cleaning and squeezing state, that is, the mop head 4 is rotated to be parallel to the mop rod 3 (or not parallel to the mop rod 3), so that the mop head 4 is inserted into the squeezing port 10. Specifically, in the cleaning state, the mop head 4 is moved and squeezed between the cleaning section 6 and the squeezer 11 of the squeezing device 7 so as to squeeze and clean the wiper. In the squeezing state, the mop head 4 is moved and squeezed between the squeezing water section 5 and the squeezer 11 of the squeezing device 7 so as to squeeze and squeeze the wiper. In addition, when the mop head 4 is pressed down, the mop head directly comes into contact with the buffer, so that the mop head 4 can be prevented from directly coming into contact with the bottom of the bucket body 1. Accordingly, the mop head is cushioned, and it is more convenient for the cleaning and squeezing operations.
In order to achieve better cleaning and squeezing effects, generally, the mop head 4 moves vertically relatively to the squeezing device 7, that is, the mop head 4 moves up and down in its axial direction. Therefore, relative movement is generated between the mop head 4 and the squeezing device 7, so that the wiper on the mop head 4 moves in relative to and against the squeezer 11 of the squeezing device 7 for cleaning or squeezing. During cleaning or squeezing, the mop rod 3 can be held and pressed down by two hands, so that the operation is very convenient and labor-saving.
To easily rotate the mop head 4, a counter weight for assisting in rotating the mop head 4 is disposed on the mop head 4 so that the mop head 4 can be rotated more easily due to the gravity of the counter weight.

When the mop head 4 is inserted into the squeezing space for squeezing, the first support functions to support and position the mop head 4 so as to prevent the mop head 4 from warping or skewing during squeezing. It is to be noted that, when the first support mechanism is used, the first support will not always be in contact with the mop head during squeezing.
Or, FIG. 50 shows a fourth kind of squeezing device, where the first support is a pair of guide plates 12″ transversely extending from a side surface of the bucket body 1, and guide slots are formed on two sides of the flow mop head. When the mop head 4 is inserted into the squeezing space, the pair of guide plates 12″ are inserted into the guide slots so as to support and position the mop head 4.
In this embodiment, in order to prevent the wrung water from retaining in the squeezing water section 5, a water flow device for transferring water in the squeezing water section 5 to the cleaning section 6 is disposed within the squeezing water section 5. The water flow device can be an existing water pumping device which directly pumps water on the bottom of the squeezing water section to the cleaning section. In this embodiment, the water flow device is a water flow passage 13″ communicating the squeezing water section 5 and the cleaning section 6, and the water flow passage 13″ is disposed over the squeezing water section 5 and the cleaning section 6. As shown in FIGS. 48-52, when the squeezer 7″ is disposed on the frame 8″, the water flow passage 13″ can be directly disposed on the frame 8″; and, when the squeezer 7″ is directly disposed on the mop bucket, the water flow passenger 13″ can be disposed in other ways.
The cleaning device comprises a cleaner 14″ for squeezing and scraping the wiper on the mop head 4 and a second support opposite to the cleaner 14″; the cleaner 14″ is directly or indirectly disposed on the bucket body 1, and the second support is directly disposed on the bucket body 1; the space between the cleaner 14″ and the second support is defined as a cleaning space; and, During cleaning, the mop head 4 is switched to the cleaning state, when the mop head 4 is inserted into the cleaning space, the wiper on the mop head 4 can move relatively to the cleaner 14″ and be squeezed by the cleaner 14″.
Switching the mop head 4 to the cleaning state generally is rotating the mop head 4 to be parallel to or approximately parallel to the mop rod 3, so that the mop head 4 can be smoothly moved up and down in the cleaning interlayer for squeezing. The specific shape and structure of the cleaner 14″ can be in various forms. For example, the cleaner 14″ is a cleaning scraper, a cleaning brush, cleaning teeth or soft cleaning rubber.
The cleaner 14″ can be directly disposed on the bucket body 1. For example, the cleaner is a cleaning scraper. Two ends of the cleaner are directly inserted into two side surfaces of the mop bucket, and the cleaner is directly connected to the mop bucket. Or, when the cleaner is a cleaning brush, cleaning teeth, soft cleaning rubber or in other structures, the cleaning brush, the cleaning teeth, the soft cleaning rubber and the like can be directly disposed on the wall of the mop bucket.
The cleaner 14″ can also be indirectly disposed on the bucket body 1. For example, FIG. 53-FIG. 58 show a first kind to sixth kind of cleaning devices, where the cleaner 14″ is disposed on a cleaning frame 15″ and the cleaning frame 15″ is then disposed on the bucket body 1.
The specific structure of the second support will not be limited as long as the second support can support and position the mop head 4 inserted into the squeezing layer. For example, FIG. 53 shows a first kind of cleaning device, where the second support is a pair of support ribs 9″ longitudinally extending from an end surface of the bucket body 1; FIG. 54 shows a second kind of cleaning device, where the second support is a pair of support ribs 9″ transversely extending from a side surface of the bucket body 1; FIG. 56 shows a fourth kind of cleaning device, where the second support is a pair of support frames 10″ longitudinally extending from an end surface of the bucket body 1, with a roller 11″ being disposed at a tail end of each of the support frames 10″; FIG. 57 shows a fifth kind of cleaning device, where the second support is a pair of support frames 10″ transversely extending from a side surface of the bucket body 1, with a roller 11″ being disposed on each of the support frames 10″; FIG. 58 shows a sixth kind of cleaning device, where the second support is a pair of support frames 10″ longitudinally extending from an end surface of the bucket body, with a pair of springs 16″ and a pair of elastic blocks 17″ being disposed in each of the support frames 10″, the springs 16″ acting on the elastic blocks 17″ to allow portions of the elastic blocks 17″ to rebound from the tail end of the support frames 10″; or, the second support is the wall of the mop bucket opposite to the cleaner 14″. When the mop head 4 is inserted into the cleaning interlayer for cleaning, the second support functions to support and position the mop head 4 so as to prevent the mop head 4 from warping or skewing during cleaning. It is to be noted that, when the second support mechanism is used, the second support will not always be in contact with the mop head 4 during cleaning.
Or, FIG. 55 shows a third kind of cleaning device, where the second support is a pair of guide plates 12″ transversely extending from a side surface of the bucket body 1, and guide slots are formed on two sides of the flow mop head 4. When the mop head 4 is inserted into the cleaning interlayer, the pair of guide plates 12″ are inserted into the guide slots so as to support and position the mop head 4.
