Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tools, and in particular to a set 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 to wring out the water and clean it.

[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 set of cleaning flat mops that realizes automatic quantitative water supply and ensures that clean water is used in every cleaning operation, in order to address the above-mentioned existing technology. This set can complete the cleaning and wringing of the mop in one area at the same time, and the amount of clean water used for each cleaning is small, thus saving water.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a set of cleaning flat mops, including 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 top of the clean water bucket is closed, the bucket wall of the clean water bucket is provided with multiple spaced reinforcing ribs, the middle parts of the clean water bucket and the washing bucket are connected by a water supply channel, the inlet end of the water supply channel is located at the bottom of the clean water bucket or the lower part of the surrounding body, and the outlet of the water supply channel is... There is a height distance between the end of the mop and the bottom of the cleaning tub. The cleaning tub is equipped with a wringer plate that squeezes the wiping material. The outlet end of the water supply channel is located below the wringer plate. The mop head and mop handle are inserted into the cleaning tub and move up and down. The inner wall of the cleaning tub supports the back plate of the mop head. The wringer plate performs a squeezing operation on the wiping material. A drainage channel is formed above the wringer plate to discharge a portion of the water squeezed off the wiping material into the outer tub, and a return water channel is formed to return a portion of the water to the cleaning tub. The direction of water return and the direction of water discharge are opposite to each other. The system also includes a switch for opening and closing the water supply channel.

[0008] To achieve a reasonable and simple structure for forming drainage and return water channels, preferably, the top surface of the aforementioned 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. Simply adding a baffle to the dewatering plate forms both drainage and return water channels, resulting in a simple structure that is easy to manufacture and assemble.

[0009] 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.

[0010] 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.

[0011] 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, where the height of the wiping material is higher than this second water level. The water returning through the return channel can absorb the wiping material above the second water 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.

[0012] 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.

[0013] To prevent water from splashing out from the top of the cleaning tub when the mop head is moved up and down, a water baffle is provided inside the cleaning tub, and the water baffle is positioned away from the back plate of the mop head entering the cleaning tub.

[0014] To facilitate assembly and ensure that the clean water tank and the washing tank do not wobble relative to the outer tank, further improvements have been made to allow the clean water tank and the washing tank to be interlocked before being installed into the outer tank.

[0015] In a further improvement, a pressure cap is fixed to the opening of the outer bucket. The pressure cap has a first through-hole for exposing the clean water bucket and a second through-hole communicating with the inner cavity of the cleaning bucket. The second through-hole forms part of the inner cavity of the cleaning bucket, and the wringer is disposed within the second through-hole. The pressure cap serves to improve the appearance of the entire outer bucket opening and also to restrain the clean water bucket and the cleaning bucket. In addition, the wringer can be pre-assembled onto the pressure cap, and then the pressure cap can be fixed to the outer bucket opening to complete the installation.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] 1. The clean water tank is filled with clean water. During cleaning, turn on the switch, and the clean water tank supplies water to the cleaning tank through the water supply channel. This creates a vacuum above the liquid surface in the clean water tank, and atmospheric pressure exerts a large pressure on the clean water tank. When the water in the cleaning tank exceeds the outlet of the water supply channel, the clean water tank automatically stops supplying water to the cleaning tank under atmospheric pressure. Therefore, the amount of water supplied each time is constant. The height distance between the outlet of the water supply channel and the bottom of the cleaning tank is the actual amount of water used for cleaning.

[0018] 2. During use, atmospheric pressure exerts a large pressure on the water bucket, making it prone to deformation. To increase the strength of the water bucket, multiple reinforcing ribs are provided on the bucket wall at intervals.

[0019] 3. When the switch is turned off, even if the liquid level drops, the clean water bucket will not supply water to the cleaning bucket. The mop head moves up and down inside the cleaning bucket, and the inner wall of the cleaning bucket supports the back plate of the mop head, ensuring sufficient squeezing force between the wringer and the wiped items. Squeezing the wiped items with the wringer will result in better cleaning. Each time, some of the wastewater squeezed off the wiped items will drain to the outer bucket through the drain channel, and some wastewater will flow back to the cleaning bucket through the return water channel to replenish and soak the wiped items in the cleaning bucket. This means that in the initial state, the water in the cleaning bucket does not need to fully soak the wiped items, thus saving water.

[0020] 4. Move the mop up and down repeatedly until the water in the cleaning bucket is mostly removed by the drain channel. This will allow you to thoroughly wring out the water from the wiped items. The cleaning and wringing process is completed in just one cleaning bucket, making the wringing 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 turn on the switch again, and the clean water bucket will supply water to the cleaning bucket again through the water supply channel. Repeat the above operation to complete the second cleaning, ensuring that the mop is cleaned with clean water every time. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-16 The figure shown is a preferred embodiment of the present invention.

[0039] A cleaning flat mop set 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.

[0040] 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 clean water tub 12 and the washing tub 13 are interlocked before being installed inside the outer tub 11. A pressure cap 8 is fixed to the opening end of the outer tub 11. The pressure cap 8 has a first through-hole 81 that exposes the clean water tub 12 and a second through-hole 82 that communicates with the inner cavity of the washing tub 13. The second through-hole 82 forms part of the inner cavity of the washing tub 13. The wringer 5 is disposed inside the second through-hole 82.

[0041] The inner wall of the cleaning tub 13 is at least partially inclined, so that the cleaning tub 13 forms an flared shape from bottom to top. A water baffle 131 is provided inside the cleaning tub 13, and the water baffle 131 is positioned away from the back plate of the mop head 3 that enters the cleaning tub 13.

[0042] The top of the clean water bucket 12 is closed, and the bucket wall of the clean water bucket 12 is provided with multiple spaced reinforcing ribs 121. The middle of the clean water bucket 12 and the cleaning bucket 13 are connected by a water supply channel D. The inlet end D1 of the water supply channel D is located at the bottom of the clean water bucket 12 or the lower part of its surrounding body. The outlet end D2 of the water supply channel D is at a height distance H from the bottom of the cleaning bucket 13. The cleaning bucket 13 is provided with a squeezing plate 5 that squeezes the wiping material 4. The outlet end D2 of the water supply channel D is located below the squeezing plate 5.

[0043] The mop head 3 and mop handle 2 are inserted into the cleaning tub 13 and move up and down. The inner wall of the cleaning tub 13 supports the back plate 31 of the mop head 3. The wringer 5 performs a squeezing operation on the wiping object 4. A drainage channel S1 is formed above the wringer 5 to drain a portion of the water squeezed off the wiping object 4 into the outer tub 11, and a portion of the water flows back into the cleaning tub 13 through a return water channel S2. The direction of water return and the direction of water discharge are opposite to each other. The cleaning tub 13 also includes a switch 6 for opening and closing the water supply channel D.

[0044] 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 facing the wiping material 4 inserted into the cleaning tub 13 is also open. The area above the baffle 51 forms the drainage channel S1. The wringer 5 is swayable, and its top surface has a further recessed transition water storage cavity 52. ​​The upwardly swaying wringer 5 can pour the water from the transition water storage cavity 52 into the outer tub 11. A limiting structure 7 is also included to limit the swaying angle range of the wringer 5. During the downward insertion of the mop head 3 into the cleaning tub 13, the wringer 5 is prevented from tilting downward by the limiting structure 7.

[0045] The initial water level height h1 is when the water in the cleaning tub 13 is above the outlet of the water supply channel D. 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 height h2. The height of the wiping material 4 is higher than the second water level height h2. The water returning through the return channel S2 can be absorbed by the wiping material 4, which is higher than the second water level height h2.

[0046] The clean water tank 12 is used to fill with clean water. During cleaning, when the switch 6 is turned on, the clean water tank 12 supplies water to the cleaning tank 13 through the water supply channel D, which can create a vacuum above the liquid surface in the clean water tank 12. Atmospheric pressure exerts a large pressure on the clean water tank 12. To ensure strength, the tank wall of the clean water tank 12 is provided with multiple spaced reinforcing ribs 121. When the water in the cleaning tank 13 exceeds the outlet end of the water supply channel D, the clean water tank 12 automatically stops supplying water to the cleaning tank 13 under the action of atmospheric pressure. Therefore, the amount of water supplied each time is constant. The height distance H between the outlet end D2 of the water supply channel D and the bottom of the cleaning tank 13 is the actual amount of water used for cleaning.

[0047] When 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. The inner wall of the cleaning tank 13 supports the back plate 31 of the mop head 3, ensuring sufficient squeezing force between the wringer 5 and the wiping object 4. The cleaning effect is better when the wringer 6 squeezes and scrapes the wiping object 4. Each time, some of the wastewater squeezed off the wiping object 4 is discharged to the outer tank 11 through the drain channel S1, and some wastewater flows back to the cleaning tank 13 through the return water channel S2 to replenish and wet the wiping object 4 in the cleaning tank 13. This means that in the initial state, the water in the cleaning tank 13 does not need to meet the condition of fully wetting the wiping object, thus saving water.

[0048] By repeatedly moving the mop up and down until the water in the cleaning bucket 13 is basically transferred away by the drain channel S1, the water on the wiped item 4 can be fully squeezed out. The cleaning and squeezing are completed in just one cleaning bucket 13, making the squeezing operation more convenient. 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. For the second cleaning, simply turn on the switch 6 again, and the clean water bucket 12 will supply water to the cleaning bucket 13 again through the water supply channel D, and repeat the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.
