Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tools, and in particular, it is a tool suitable for cleaning flat mops or foam flat mops. Background Technology

[0002] For cleaning flat mops or foam flat mops, most mop buckets need to be filled with water before placing the mop in for cleaning. Only the first cleaning uses clean water; subsequent cleanings use water that is slightly cleaner than the previous cleaning. After cleaning, the mop should be wrung out in another area.

[0003] For example, Chinese utility model patent CN201821203889.3 (publication number CN209863678U) discloses a flat mop tool, including a mop bucket and a flat mop. The mop bucket has a separate wringing area and a separate water-holding area, and the wringing area is equipped with a squeezing device. The flat mop includes a cleaning material, a mop handle, and a flat mop plate connected to the lower end of the mop handle. In use, the flat mop is rotated to a squeezing state, and then the squeezing device is inserted into the wringing area. The mop moves up and down to squeeze the cleaning material, and the squeezed water is transferred to the water-holding area through a water transfer device. Since the amount of water squeezed out when the cleaning material is squeezed is greater than the amount of water entering the wringing area from the water-holding area through the slow-release mechanism, after multiple repetitions, almost all the water in the wringing area can be transferred to the water-holding area, and the cleaning material is also squeezed dry in the process. Afterwards, the water in the water-holding area enters the wringing area through the slow-release mechanism. When the flat mop gets dirty, it can then enter the wringing area for wringing and cleaning.

[0004] While the aforementioned patent allows for cleaning and wringing operations within the same area (the wringing zone), the wastewater washed off the mop each time is discharged back into the water collection area, contaminating the water cup in that area. This contaminated water then enters the wringing zone via a slow-release mechanism, meaning the water used for the next mop wash is not clean, affecting the cleanliness of the mop. Furthermore, the amount of water released into the wringing zone each time through the slow-release mechanism cannot be precisely controlled; the amount of water used to wash the mop is not fixed, and the water may not fully submerge the mop, further affecting its cleanliness.

[0005] In conclusion, how to achieve automatic quantitative water supply is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a tool for cleaning flat mops that ensures that each cleaning operation uses clean water and uses less water per cleaning operation, and that the cleaning operation is completed in only one area, in light of the above-mentioned existing technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning device for a flat mop, comprising a cleaning bucket and a mop, wherein the mop includes a mop head rotatably connected to the lower end of the mop handle, and a wiping agent is provided on the mop head; the cleaning bucket has a first chamber, a second chamber, and a third chamber that are independent of each other; characterized in that: the first chamber and the second chamber are connected by a flow channel, the flow channel is provided with an opening and closing element, the first chamber is used to add and store clean water, the second chamber is used to receive the clean water flowing in through the flow channel and allow the mop head to enter for cleaning, and the lower end of the wiping agent is sleeved or fastened to the back plate of the mop head; The third chamber is used to collect some of the wastewater squeezed off the wiping material. The second chamber is equipped with a scraper plate, which is located above the flow channel. Above the scraper plate, a drainage channel is formed to discharge some of the water squeezed off the wiping material into the third chamber, and a return channel is formed to return some of the water to the second chamber. The direction of water return and the direction of water discharge are opposite to each other. The bottom surface of the wiping material is attached to the back plate of the mop head. The mop head is rotated to a squeezeable state that is basically parallel to the mop handle. In this state, the mop head and the mop handle are inserted into the second chamber and move up and down, squeezing the wiping material through the scraper plate.

[0008] To ensure a reasonable layout, the drainage channel is located above the return water channel, and at least partially connected to the return water channel. Alternatively, the drainage channel can be located below the return water channel, for example, by creating a drainage hole below the return water channel that drains into the third chamber; the drainage hole constitutes the drainage channel.

[0009] To rationally form drainage and return water channels, the top surface of the aforementioned scraper has an upwardly extending enclosure, which together with the scraper forms the return water channel. The upper end of the return water channel is open, and the end of the return water channel facing the wiping material inserted into the second cavity is also open. The area above the enclosure forms the drainage channel.

[0010] Preferably, the aforementioned enclosure has a rear wall, a left side wall, and a right side wall. The semi-enclosed enclosure allows water from the return channel to be concentrated and transferred onto the object being wiped. Of course, it is also possible to have only a rear wall.

[0011] To fully transfer water from the second chamber to the third chamber, the aforementioned scraper can swing. The top surface of the scraper has a further recessed transition water storage chamber. The upward swinging scraper can pour the water from the transition water storage chamber into the third chamber. After several washes, the amount of water on the wiped item is small, and the energy of the squeezed water is insufficient to directly drain into the third chamber. In this case, the small amount of squeezed water will be stored in the transition water storage chamber. The water in the transition water storage chamber can be drained into the third chamber by swinging, or a drain hole can be provided at the bottom of the transition water storage chamber to drain into the outer tub or other places.

[0012] To ensure the scraper blade swings within a suitable angle range, a limiting structure is included to restrict the swing angle range of the scraper blade. During the downward movement of the mop head into the second chamber, the scraper blade is prevented from flipping downwards by the limiting structure. If the scraper blade flips forward at too large an angle, water in the transition water storage chamber may be drained into the second chamber. The goal is to ensure that water in the transition water storage chamber does not drain into the second chamber, but rather drains as much as possible into the third chamber. Furthermore, an excessively large forward flip angle can also affect the scraping action of the scraper blade on the wiping material.

[0013] To facilitate quick rotation and installation of the extrusion scraper into the second cavity, pivots are provided on both the front and rear sides of the extrusion scraper, and the extrusion scraper is rotatably installed into the second cavity via the pivots.

[0014] Compared with the prior art, the advantages of this utility model are as follows: The cleaning bucket has three independent chambers: a first chamber, a second chamber, and a third chamber. The first chamber is filled with clean water. During cleaning, the opening and closing element is opened, and the first chamber supplies water to the second chamber through the flow channel. Because the top of the first chamber is closed, when the water in the second chamber exceeds the outlet of the flow channel, the first chamber automatically stops supplying water to the second chamber under atmospheric pressure. Therefore, the amount of water supplied each time is constant. Then, the opening and closing element is closed. Even if the liquid level drops, the first chamber will never supply water to the second chamber. The mop head moves up and down in the second chamber, using a scraper to scrape and clean the object being wiped. The lower end of the object is fitted or fastened to the back plate of the mop head, and the bottom surface of the object is adhered to the back plate of the mop head. In this way, during the downward movement of the mop head, the lower end of the object, fitted or fastened to the back plate of the mop head, will not warp under the scraping action of the scraper, ensuring smooth and unobstructed cleaning operation. Each time the wastewater is squeezed off the cleaning surface, some of it flows through the drain channel to the third chamber, while some flows back through the return channel to the second chamber to replenish the cleaning surface. This means that initially, the water in the second chamber does not need to completely soak the cleaning surface, thus saving water. By repeatedly moving the mop up and down until the water in the second chamber is mostly removed by the drain channel, the water on the cleaning surface can be thoroughly squeezed out. The cleaning and squeezing are completed in just one second chamber, making the squeezing operation more convenient. The direction of water return and the direction of water discharge are opposite to each other, and they are independent and do not interfere with each other. For the second cleaning, simply open the opening and closing element again, and the first chamber will supply water to the second chamber again through the flow channel, and the above operation will be repeated to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-16The figure shown is a preferred embodiment of the present invention.

[0033] A cleaning device for a flat mop includes a cleaning bucket 1 and a mop. The mop includes a mop head 3 rotatably connected to the lower end of the mop handle 2. The mop head 3 is provided with a wiping material 4, which can be a fiber cloth or foam.

[0034] The cleaning bucket 1 has three independent chambers: a first chamber 1a, a second chamber 1b, and a third chamber 1c. The first chamber 1a and the second chamber 1b are connected by a flow channel D, which is equipped with an opening and closing element 5. The first chamber 1a is used to add and store clean water, and the second chamber 1b is used to receive the clean water flowing in through the flow channel D and to allow the mop head 3 to enter for cleaning. The lower end of the wiping material 4 is fitted or fastened to the back plate 31 of the mop head 3. The third chamber 1c is used to receive some of the wastewater squeezed off from the wiping material 4. The second chamber 1b is equipped with a scraper 6, which is located above the flow channel D.

[0035] Above the scraper 6, a drainage channel S1 is formed to drain a portion of the water scraped off the wiping material 4 into the third chamber 1c, and a return water channel S2 is formed to return a portion of the water to the second chamber 1b. The direction of water return and water discharge are opposite to each other. The bottom surface of the wiping material 4 is adhered to the back plate 31 of the mop head 3. The mop head 3 is rotated to a squeezeable state that is basically parallel to the mop handle 2. In this state, the mop head 3 and the mop handle 2 are inserted into the second chamber 1b and move up and down, scraping the wiping material 4 by the scraper 5. The drainage channel S1 is located above the return water channel S2, and the drainage channel S1 is at least partially connected to the return water channel S2.

[0036] The top surface of the scraper 6 has an upwardly extending surrounding plate 61, which, together with the scraper 6, forms the return water channel S2. The upper end of the return water channel S2 is open, and the end of the return water channel S2 is open towards the wiping material 4 inserted into the second cavity 1b. The area above the surrounding plate 61 forms the drainage channel S1. The surrounding plate 61 has a rear wall 611, a left side wall 612, and a right side wall 613.

[0037] The scraper blade 6 is oscillating, and pivots 63 are provided on its front and rear sides. The scraper blade 6 is rotatably mounted in the second cavity 1b via the pivots 63. The top surface of the scraper blade 6 has a further recessed transition water storage cavity 62. The upward oscillating scraper blade 6 can pour the water in the transition water storage cavity 62 into the third cavity 1c. A limiting structure 7 is also included to limit the oscillation angle range of the scraper blade 6. During the downward movement of the mop head 3 into the second cavity 1b, the scraper blade 6 is prevented from tilting downward by the limiting structure 7.

[0038] During cleaning, the opening and closing element 6 is opened, and water is supplied from the first chamber 1a to the second chamber 1b through the flow channel D. Then, the opening and closing element 5 is closed. Even if the liquid level drops, the first chamber 1a will never supply water to the second chamber 1b. The mop head 3 moves up and down in the second chamber 1b and uses the scraper 6 to scrape and clean the wiping material 4. The lower end of the wiping material 4 is fitted or fastened to the back plate 31 of the mop head 3, and the bottom surface of the wiping material 4 is adhered to the back plate 31 of the mop head 3. In this way, during the downward movement of the mop head 3, the lower end of the wiping material 4 will not warp under the action of the scraper 6 because it is fitted or fastened to the back plate 31 of the mop head 3, ensuring that the cleaning operation is smooth and without jamming. Each time, some wastewater is squeezed off the wiping material 4 and discharged into the third chamber 1c through the drain channel S1. Some wastewater flows back into the second chamber 1b through the return water channel S2 to replenish and wet the wiping material 4 in the second chamber 1b. This means that in the initial state, the water in the second chamber 1b does not need to fully wet the wiping material 4, thus saving water. By repeatedly moving the mop up and down until the water in the second chamber 1b is basically transferred away by the drain channel S1, the water on the wiping material 4 can be fully squeezed out. The cleaning and squeezing are completed in only one second chamber 1b, making the water squeezing operation more convenient. The direction of water return and the direction of water discharge are opposite to each other and do not interfere with each other. For the second cleaning, simply open the opening and closing element 6 again, and the first chamber 1a supplies water to the second chamber 1b again through the flow channel D, and repeat the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.
