Description

Technical Field

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

[0002] Most mop buckets for cleaning flat mops or foam flat mops require filling the bucket with water before placing the mop inside. Only the first rinse uses clean water; subsequent rinses use water that is slightly cleaner than the previous rinse. After cleaning, the mop is wrung out in a separate area. Numerous patents exist for mop buckets designed to clean flat mops. The core concept is that the mop bucket has separate wringing and water-holding areas. The water-holding area is used to clean the mop, while the wringing area is used to wring it dry. The water squeezed out of the mop is transferred to the water-holding area via a water transfer device.

[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] This type of flat mop cleaning tool has the following drawbacks: Each cleaning cycle requires a full water supply, necessitating refilling from the tap afterward. It lacks automatic water supply to the washing area, and the washing and wringing processes are separated into two distinct zones, requiring two separate operations to complete a single cleaning session, making the process inconvenient. Furthermore, wastewater from each cleaning cycle is discharged back into the water collection area, contaminating the water cup. This contaminated water then flows through the slow-release mechanism into the wringing area, meaning the water used for the next mop wash is not clean, affecting the cleanliness of the wiped items. The slow-release mechanism may have small, non-closable holes, meaning the lower part of the wiped item may remain soaked in water during the wringing process, resulting in poor wringing and incomplete drying.

[0005] In conclusion, the aforementioned flat mop cleaning tool can be further improved. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a cleaning tool for a flat mop that achieves automatic quantitative water supply and ensures that each cleaning operation uses clean water, in light of the above-mentioned existing technology. This cleaning tool can simultaneously clean and wring out the mop in one area, and uses less clean water each time, thus saving water.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning tool 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 the mop head is provided with a wiping agent; characterized in that: the cleaning bucket includes an outer bucket, a clean water bucket, and a washing bucket, wherein the clean water bucket and the washing bucket are at least partially installed inside the outer bucket, the outer wall of the washing bucket and the corresponding inner wall of the outer bucket abut against each other through a blocking part, the outer bucket provides support for the clean water bucket and the washing bucket, the top of the clean water bucket is closed, and the middle parts of the clean water bucket and the washing bucket are connected through a water supply channel, the water supply channel is controlled to open and close by a switch, and the inlet end of the water supply channel... Located at the bottom of the water tank or the lower part of the surrounding structure, the outlet end of the water supply channel is at a height distance from the bottom of the cleaning tank. The cleaning tank is equipped with a wringer to squeeze the wiping material. The lower end of the wiping material is sleeved or fastened to the back plate, and the bottom surface of the wiping material is adhered to the back plate. The mop head is rotated to a squeezing state that is basically parallel to the mop handle. In this state, the mop head and mop handle are inserted into the cleaning tank and move up and down. Above the wringer, a drainage channel is formed to discharge some of the water squeezed off the wiping material into the outer tank, and a return water channel is formed to return some of the water to the cleaning tank. The direction of water return and the direction of water discharge are opposite to each other.

[0008] To provide a simple and effective support for the clean water tank and the washing tank, the outer tank is equipped with a support column, support platform, or support frame to support the clean water tank and the washing tank. The support column, support platform, or support frame can extend upward from the bottom surface of the outer tank, or it can extend inward from the side wall of the outer tank. It can also be a component that is independently fixed inside the outer tank, or it can be fixed to the clean water tank and the washing tank.

[0009] To achieve a reasonable and simple structure for forming drainage and return water channels, preferably, the top surface of the dewatering plate has an upwardly extending baffle. The baffle and the dewatering plate together form the return water channel, with the upper end of the return water channel open and the end facing the wiping material inserted into the cleaning bucket also open. The area above the baffle forms the drainage channel. Only the baffle is needed to form drainage and return water channels on the dewatering plate, resulting in a simple structure that is easy to manufacture and assemble.

[0010] To fully transfer water from the cleaning tub to the outer tub, the aforementioned wringer is oscillating. The top surface of the wringer has a further recessed transition water storage cavity. The upward-oscillating wringer pours water from the transition water storage cavity into the outer tub. After several washes, when the amount of water on the wiped item is small and the energy of the squeezed water is insufficient to directly drain into the outer tub, the small amount of squeezed water is stored in the transition water storage cavity. This water can be drained into the outer tub via oscillation or through a drain hole at the bottom of the transition water storage cavity.

[0011] To ensure the squeegee swings within a suitable angle range, a limiting structure is included to restrict the swing angle range of the wringer. As the mop head descends into the cleaning tub, the wringer is prevented from flipping downwards by this limiting structure. If the forward flip angle is too large, water in the transition water storage chamber may be drained into the cleaning tub. Therefore, the goal is to ensure that as much water as possible in the transition water storage chamber is drained into the outer tub rather than into the cleaning tub.

[0012] To further conserve water, preferably, the initial water level is set when the water in the washing tub surpasses the outlet of the water supply channel. With the mop head fully inside the washing tub, the water level rises to a second water level. The height of the wiping material is higher than this second water level, allowing the water returning through the return channel to absorb the wiping material above this level. The wiping material above the second water level is not wetted; this portion can be wetted by the water returning from the diversion component.

[0013] As a further improvement, the aforementioned cleaning tub is equipped with a water baffle plate located below the wringer. This water baffle plate prevents water from entering the outer tub from below the wringer, ensuring that the water level in the cleaning tub is sufficient for multiple cleaning cycles.

[0014] To ensure that even with a small amount of water, the maximum water level in the washing tub rises as high as possible after the mop enters, at least one inner wall of the washing tub is partially inclined, so that the washing tub forms an flared shape from bottom to top.

[0015] To prevent water from splashing out from the top of the cleaning tub when the mop head is moved up and down, a water-stop plate is provided inside the cleaning tub, and the water-stop plate is positioned away from the back plate of the mop head that enters the cleaning tub.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the cleaning bucket includes an outer bucket, a clean water bucket, and a washing bucket that are independent of each other. The clean water bucket is filled with clean water. When washing, the switch is turned on, and the clean water bucket supplies water to the washing bucket through the water supply channel. Because the top of the clean water bucket is closed, when the water in the washing bucket exceeds the outlet of the water supply channel, the clean water bucket automatically stops supplying water to the washing bucket under atmospheric pressure. Therefore, the amount of water supplied each time is constant, and the height distance between the outlet of the water supply channel and the bottom of the washing bucket is the actual amount of water used for washing. Then, turn off the switch. Even if the liquid level drops, the clean water bucket will never supply water to the washing bucket. The mop head moves up and down inside the washing bucket, using the wringer to scrape and clean the items being wiped. Each time, some of the wastewater scraped off the items is drained to the outer bucket through the drain channel, while some wastewater flows back to the washing bucket through the return water channel to replenish and soak the items inside. This means that initially, the water in the washing bucket does not need to completely soak the items, thus saving water. Repeat the up-and-down movement of the mop until the water in the washing bucket is mostly drained through the drain channel, thoroughly squeezing out the water from the items. The washing and wringing process is completed within the washing tub, making wringing more convenient. The outer wall of the washing tub and the corresponding inner wall of the outer tub are abutted by a stop, preventing the washing tub from shaking during washing. The direction of water return and the direction of water discharge are opposite to each other, and the two are independent and do not interfere with each other. During the washing process, the corresponding inner wall of the washing tub supports the back plate of the mop head, ensuring the wringing board has the force to squeeze and wipe the objects, resulting in better wringing effect. For a second wash, simply open the opening and closing element again, and the clean water tub will supply water to the washing tub again through the water supply channel, and repeat the above operation to complete the second wash, ensuring that the mop is washed with clean water every time.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-12 The figure shown is a preferred embodiment of the present invention.

[0031] A cleaning tool 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, and the mop head 3 is provided with a wiping material 4. The wiping material 4 can be a fiber cloth or foam.

[0032] The cleaning tub 1 includes an outer tub 11, a clean water tub 12, and a washing tub 13. The clean water tub 12 and the washing tub 13 are at least partially installed inside the outer tub 11. The outer tub 11 has a support column, support platform, or support frame 8 that supports the clean water tub 12 and the washing tub 13. The support column, support platform, or support frame 8 can extend upward from the inner bottom surface of the outer tub 11, or it can extend inward from the side wall of the outer tub 11. It can also be a component that is independently fixed inside the outer tub 11, or it can be fixed to the clean water tub 12 and the washing tub 13. The outer wall of the washing tub 13 has a protruding stop portion 132 that abuts against the corresponding inner wall of the outer tub 11. One inner wall 132 of the washing tub 13 is at least partially inclined, so that the washing tub 13 forms a flared shape from bottom to top.

[0033] The top of the clean water bucket 12 is closed. The middle of the clean water bucket 12 and the washing bucket 13 are connected by a water supply channel D. The inlet of the water supply channel D is located at the bottom of the clean water bucket 12 or at the lower part of its surrounding structure. The outlet of the water supply channel D is at a height distance H from the bottom of the washing bucket 13. The washing bucket 13 is provided with a wringing plate 5 that squeezes the wiping material 4. The lower end of the wiping material 4 is fitted or fastened to the back plate, and the bottom surface of the wiping material 4 is adhered to the back plate. The mop head 3 is rotated to engage with the mop handle 2. In a basically parallel, compressible state, the mop head 3 and mop handle 2 are inserted together into the cleaning tub 13 and move up and down. The corresponding inner wall of the cleaning tub 13 supports the back plate 31 of the mop head 3. A drainage channel S1 is formed above the wringer 5 to drain a portion of the water squeezed off the wiping material 4 into the outer tub 11 and a return water channel S2 to return a portion of the water to the cleaning tub 13. The direction of water return and the direction of water discharge are opposite to each other. It also includes a switch 6 for opening and closing the water supply channel D.

[0034] The top surface of the wringer 5 has an upwardly extending baffle 51, which together with the wringer 5 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 cleaning tub 13. The area above the baffle forms the drainage channel S1.

[0035] The wringer plate 5 is oscillating, and its top surface has a further recessed transition water storage cavity 52. ​​The upward oscillating wringer plate 5 can pour the water from the transition water storage cavity 52 into the outer bucket 11. It also includes a limiting structure 7 that limits the oscillation angle range of the wringer plate 5. During the downward movement of the mop head 3 into the cleaning bucket 13, the wringer plate 5 is prevented from tilting downwards by the limiting structure 7.

[0036] When the water level in the cleaning tub 13 exceeds the outlet of the water supply channel D, the initial water level is h1. When the mop head 3 is fully inside the cleaning tub 13, the water level in the cleaning tub 13 rises to the second water level h2. The height of the wiping material 4 is higher than the second water level h2, and the water flowing back through the return channel S2 can be absorbed by the wiping material 4 which is higher than the second water level h2.

[0037] The cleaning tub 13 is equipped with a water-stop plate 133, which is positioned away from the back plate of the mop head 3 that enters the cleaning tub 13. The cleaning tub 13 is also equipped with a water-blocking plate 131, which is located below the wringer plate 5.

[0038] The cleaning tank 1 includes an outer tank 11, a clean water tank 12, and a washing tank 13, which are independent of each other. The clean water tank 11 is filled with clean water. When washing, the switch 6 is turned on, and the clean water tank 12 supplies water to the washing tank 13 through the water supply channel D. Because the top of the clean water tank 12 is closed, when the water in the washing tank 12 exceeds the outlet D1 of the water supply channel D, the clean water tank 12 will automatically stop supplying water to the washing tank 13 under atmospheric pressure. Therefore, the amount of water supplied each time is constant. The height distance H between the outlet D1 of the water supply channel D and the bottom of the washing tank 13 is the actual amount of water used for washing. Then, switch 6 is turned off. Even if the liquid level drops, the clean water tank 12 will never supply water to the cleaning tank 13. The mop head 3 moves up and down inside the cleaning tank 13, squeezing and cleaning the wiping material 4 through the wringer 5. Each time, some wastewater squeezed off the wiping material 4 is discharged into the cleaning tank 13 through the drain channel S1, and some wastewater flows back into the cleaning tank 13 through the return water channel S2 to replenish and wet the wiping material 4 inside the cleaning tank 13. This means that in the initial state, the water in the cleaning tank 13 does not need to fully wet the wiping material 4, thus saving water. After repeatedly moving the mop up and down several times, the amount of water on the wiping material 4 is small, and the energy of the squeezed water is insufficient to be directly discharged into the outer tank 11. The small amount of squeezed water will be stored in the transition water storage chamber 52. The water in the transition water storage chamber 52 can be discharged into the outer tank 11 by swinging, or it can be stored in the transition water storage chamber. The bottom of the water chamber 52 has a drain hole that drains into the outer tub 11. The water in the washing tub 13 is basically transferred away by the drain channel S1, which can fully squeeze the water out of the wiping object 4. The washing and squeezing are completed in just one washing tub 13, making the squeezing operation more convenient. The outer wall of the washing tub 13 and the corresponding inner wall of the outer tub 11 are abutted by the stop part 132, so that the washing tub 13 is not easy to shake during washing. The direction of water return and the direction of water discharge are opposite to each other, and the two are independent and do not interfere with each other. During the washing process, the corresponding inner wall of the washing tub 13 supports the back plate 31 of the mop head 3, which can ensure the force of the wringing plate 5 to squeeze and scrape the wiping object, and the squeezing effect is better. For the second washing, simply turn on the switch 6 again, and the clean water tub 12 supplies water to the washing tub 13 again through the water supply channel D, and repeat the above operation to complete the second washing, ensuring that the mop is washed with clean water every time.
