Description

Technical Field

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

[0002] There are numerous patents related to mop buckets used for cleaning flat mops. A representative patent is Chinese utility model patent CN201821203889.3 (publication number CN209863678U), which 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. Moving it up and down squeezes the cleaning material, and the squeezed water is transferred to the water-holding area via a water transfer device. Because the amount of water squeezed out 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 during this 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.

[0003] The applicant of the aforementioned patent has also applied for many similar patents with different focuses of protection, but the core of them is that the mop bucket has an independent squeezing area and an independent water holding area, and the water squeezed out of the wiping material is transferred to the water holding area through a water transfer device.

[0004] This indicates that flat mop cleaning tools have the following drawbacks:

[0005] 1. Each time the wastewater is washed off the mop, it is discharged back into the water collection area, causing the water cup in the water collection area to become contaminated. The contaminated water in the water collection area then enters the squeezing area through the slow release mechanism, so the water used to wash the mop next time is not clean water, which affects the cleanliness of the mop.

[0006] 2. The amount of water released into the wringing zone through the slow-release mechanism each time cannot be quantitatively controlled. That is, the amount of water used to wash the mop each time is not fixed, and the water used to wash the mop may not fully submerge the objects being wiped, further affecting the cleanliness of the objects.

[0007] 3. The slow-release mechanism may be a small hole that cannot be closed. In this case, during the cleaning and squeezing process, the lower end of the wipe may always be soaked in water in the squeezing area, which will reduce the squeezing effect and prevent the wipe from being fully squeezed out.

[0008] In conclusion, the aforementioned cleaning tools for cleaning flat mops or sponge mops can be further improved. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a detachable squeeze flat mop cleaning tool that separates clean water and wastewater, making it possible to use clean water for each mop wash, in light of the above-mentioned existing technology.

[0010] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a detachable squeezing flat mop cleaning tool, including a mop bucket and a flat mop, the flat mop including a mop handle and a flat mop head movably connected to the mop handle, the flat mop head being provided with a wiping material; the mop bucket has an independent clean water area, an independent squeezing area, and an independent wastewater area; a squeezing device is installed on the mop bucket, and during washing and squeezing, the flat mop head is rotated to a state where washing and squeezing can be performed, and during washing and squeezing, the flat mop head moves and squeezes between the squeezing area and the squeezing device to move, squeeze, and squeeze the wiping material; the characteristic is that: the mop bucket includes a clean water bucket, a squeezing bucket, and a wastewater bucket, the space inside the clean water bucket forms the clean water area, the space inside the squeezing bucket forms the squeezing area, and the space in the wastewater bucket forms the wastewater area; the squeezing bucket is provided with a squeezing device for squeezing water, at least part of the squeezing bucket or the clean water bucket can be placed in the wastewater bucket, and at least one of the squeezing bucket or the clean water bucket can be separated from the wastewater bucket.

[0011] To achieve simultaneous cleaning and wringing within the wringer bucket, the aforementioned wringer bucket is equipped with a water transfer device for transferring the squeezed-out water to the wastewater bucket. During cleaning, the wringer bucket is filled with water. The flat mop head enters the wringer bucket and moves up and down, using the wringing device to scrape and clean the object being wiped. Each time wastewater is squeezed from the object, it is transferred to the wastewater area via the water transfer device. This process is repeated multiple times until all the water in the wringer bucket is removed. A few more up-and-down movements of the flat mop head then thoroughly wring out the water from the object.

[0012] Preferably, the water transfer device described above is a water flow channel. Of course, it can also be a pumping device.

[0013] As an improvement, the aforementioned extrusion device is a dewatering plate or a dewatering roller, with the water passage formed above the dewatering plate. No additional components are needed to form the water passage.

[0014] Further improvements include an upward-extending baffle on the wringer plate. The wringer plate and baffle form a return water channel. As the flat mop head moves downward into the wringer bucket, the water in the return water channel is absorbed by the object being wiped. The baffle blocks some of the water squeezed off the object, allowing the water transferred to the wringer bucket via the return water channel to moisten the upper part of the object being wiped on the flat mop head before it enters the wringer bucket. This means the water in the wringer bucket can partially submerge the object, resulting in less water being used per wash and making this cleaning tool more water-saving and environmentally friendly.

[0015] To further improve the system and ensure efficient transfer of water from the wringer to the wastewater tank, the wringer plate is designed to swing. The wringer plate has a recessed water storage trough. As the mop head moves downwards into the wringer, the water storage trough collects some of the water squeezed from the wiped surface. As the mop head moves upwards away from the wringer, it causes the wringer plate to rotate in the opposite direction, discharging the water from the storage trough into the wastewater tank. After several washes, when the amount of water on the wiped surface is reduced and the squeezed water lacks sufficient energy to be transferred to the wastewater tank via the water flow channel, the remaining water is stored in the storage trough. This water can be discharged into the wastewater tank via a swing mechanism or through a drain hole at the bottom of the storage trough.

[0016] To ensure the wringer swings within a suitable angle range, a limiting structure is included to restrict the swing angle of the wringer. As the flat mop head moves downwards into the wringer bucket, the wringer flips forward to a first position and is blocked by the limiting structure. If the forward flip angle is too large, water in the water storage tank may be drained into the wringer bucket. The goal is to ensure that water in the water storage tank is not drained into the wringer bucket, but rather that as much water as possible is drained into the wastewater bucket.

[0017] To achieve a metered water supply from the purified water tank to the squeezing tank, the purified water tank and the squeezing tank are connected by a water supply channel, which is controlled by a switch. The switch is turned on to supply water, and turned off once the required amount is supplied.

[0018] As an improvement, the switch is lowered to close the water supply channel, and raised to open it. The mop works in conjunction with the switch, causing the switch to move downwards as the mop moves downwards. This structure automatically closes the switch by lowering the mop, eliminating the need for manual closing and creating a linkage with the mop. The design is more rational and aligns with user habits.

[0019] In a further improvement, the switch is elongated and is constrained to the inner wall of the squeezing bucket by a ribbed guide structure. During the downward movement of the switch, the ribbed guide structure applies a force to the switch towards the outlet end of the water supply channel. This ribbed guide structure ensures the switch follows a predetermined trajectory and applies a force towards the outlet end of the water supply channel, allowing the switch to more effectively close the outlet end of the water supply channel and prevent leakage. Of course, the switch can also take other forms, such as a ball valve or other on / off switch structures.

[0020] To facilitate user operation, the upper end of the switch extends above the wringer bucket for operation, and the upper end of the switch has a groove or rib for operation. For easy linkage with a mop, the middle of the switch has a protruding linkage part that engages with the downward-moving mop.

[0021] To ensure that the switch does not move further after it has been lowered into position, the aforementioned squeezing bucket is equipped with a stop that blocks the switch when it is lowered to close the water supply channel.

[0022] To achieve automatic, metered water supply from one water purifier to another, the top of the aforementioned water purifier is sealed. Water supply to the squeezing bucket stops once the water in the squeezing bucket has submerged the outlet of the water supply channel. During cleaning, the switch is turned on, and the water purifier supplies water to the squeezing bucket via the water supply channel. Once the water in the squeezing bucket has submerged the outlet of the water supply channel, due to the sealed top of the water purifier and atmospheric pressure, the water purifier stops supplying water to the squeezing bucket, thus ensuring a consistent water volume each time.

[0023] Preferably, the water supply channel also functions as an air intake channel, allowing air to enter the space above the liquid surface in the purified water tank simultaneously with water being poured into the squeezing bucket, until the water in the squeezing bucket submerges the outlet of the water supply channel. This better utilizes atmospheric pressure. Once the water in the squeezing bucket submerges the outlet of the water supply channel, the purified water tank stops supplying water to the squeezing bucket. When the water in the squeezing bucket does not submerge the outlet of the water supply channel and the switch is open, water from the purified water tank automatically supplies water to the squeezing bucket. At the same time, air enters the space above the effective liquid surface in the purified water tank through the water supply channel, ensuring smooth water supply without the need for an additional air intake valve, resulting in a simpler structure. Of course, a one-way air intake valve could also be installed in another location on the purified water tank, but this would complicate the structure.

[0024] Preferably, the water supply channel is horizontally positioned, or it is inclined downwards from the inlet to the outlet, or at least the top of the inlet is higher than the top of the outlet. This facilitates air entry into the clean water tank when the water supply channel drains into the squeezing bucket, ensuring that water can be quickly discharged from the water supply channel.

[0025] Preferably, there is a height distance between the bottom of the water supply channel and the squeezing area. The smaller the height distance, the less water is needed to block the outlet of the water supply channel, allowing the water in the water purifier to be used more times; however, if too little water flows into the squeezing bucket, it cannot guarantee that the water will be sufficient to submerge the wiping material, affecting the cleaning effect. The height distance is between one-sixth and two-thirds of the height of the squeezing bucket.

[0026] To conserve water, preferably, the initial water level is set when the water in the wringer bucket covers the outlet of the water supply channel. With the flat mop head fully inside the wringer bucket, the water level rises to a second water level, and the height of the wiping material is higher than this second water level. The wiping material above the second water level is not wetted; this portion can be wetted by water transferred from the return water channel.

[0027] To ensure a sealed top, the water purifier consists of a barrel body with an open top and a lid, with the lid covering the opening of the barrel body to create a seal. Dividing the water purifier into two parts facilitates manufacturing.

[0028] To facilitate water filling, the bucket lid is equipped with a water inlet, which is sealed with a plug.

[0029] Preferably, the inlet of the water supply channel is located at the bottom of the water purifier tank or at the lower part of its surrounding structure. Positioning the inlet of the water supply channel at the bottom of the water purifier tank ensures that all water is completely drained, resulting in high water purification efficiency.

[0030] As an improvement, the side wall or bottom of the aforementioned water purifier bucket has a first insertion part, and the first insertion part has a first through hole communicating with the outside and its inner cavity. The side wall of the squeezing bucket has a second insertion part, and the second insertion part has a second through hole communicating with the outside and its inner cavity. The second insertion part is inserted into the first through hole, and the second through hole constitutes the water supply channel; alternatively, the first insertion part is inserted into the second through hole, and the first through hole constitutes the water supply channel. The water supply channel is formed by the interlocking insertion parts, ensuring that the water supply channel has a certain length. Of course, the water supply channel can also be a hole on the side wall.

[0031] To ensure that the water in the purified water tank can supply water to the squeezing water tank multiple times, the purified water tank and the squeezing water tank are staggered vertically.

[0032] In a further improvement, a support component is provided between the bottom of the purified water tank and the inner bottom surface of the wastewater tank. This support component can be a support column located on the inner bottom surface of the wastewater tank and extending upwards, or a support column located on the bottom of the purified water tank and extending downwards, or a support column located on the inner wall of the wastewater tank and extending inwards to support the bottom of the purified water tank. Because the purified water tank and the squeezing tank are arranged in a staggered manner, the support component provides support for the purified water tank, thereby more stably fixing the purified water tank inside the wastewater tank.

[0033] Compared with the prior art, the advantages of this utility model are: the sewage bucket, the clean water bucket and the clean water bucket are independent components, which is convenient for manufacturing. During assembly, it is only necessary to fix the clean water bucket and the clean water bucket into the sewage bucket. The clean water area, the squeezing area and the sewage area are independent of each other, which makes it possible to use clean water every time the mop is washed. Cleaning and squeezing can be completed only in the squeezing bucket. There is only one squeezing device, which reduces costs. Attached Figure Description

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] like Figures 1-13 The figure shown is a preferred embodiment of the present invention.

[0049] A detachable squeezing flat mop cleaning tool includes a mop bucket 1 and a flat mop. The flat mop includes a mop handle 2 and a flat mop head 3 movably connected to the mop handle 2. The flat mop head 3 is provided with a wiping material 4. The wiping material 4 can be a fiber cloth or foam.

[0050] The mop bucket 1 has an independent clean water area 1a, an independent wringing water area 1b, and an independent wastewater area 1c; the mop bucket 1 is equipped with a squeezing device. When cleaning and wringing water, the flat mop head 3 is rotated to a state where cleaning and wringing water can be performed. During cleaning and wringing water, the flat mop head 3 moves and squeezes between the wringing water area 1b and the squeezing device to move, squeeze, and wring water from the wiping material 4.

[0051] The mop bucket 1 includes a clean water bucket 11, a wringer bucket 12, and a wastewater bucket 13. The space inside the clean water bucket forms the clean water zone 1a, the space inside the wringer bucket 12 forms the wringer zone 1b, and the space in the wastewater bucket 13 forms the wastewater zone 1c. The wringer bucket 12 is provided with a squeezing device for squeezing water. At least part of the wringer bucket 12 or the clean water bucket 11 can be placed into the wastewater bucket 13, and at least one of the wringer bucket 12 or the clean water bucket 11 can be separated from the wastewater bucket 13.

[0052] The squeezing bucket 12 is equipped with a water transfer device for transferring the squeezed water to the wastewater bucket 13. The water transfer device is a water flow channel S1.

[0053] The squeezing device is a squeezing plate 5 or a squeezing roller, and the water passage S1 is formed above the squeezing plate 5. The squeezing plate 5 is provided with an upwardly extending baffle 51. The squeezing plate 5 and the baffle 51 form a return water passage S2. During the process of the flat mop head 3 entering the squeezing bucket 12 downward, the water in the return water passage S2 can be absorbed by the wiping material 4.

[0054] The wringer plate 5 is oscillating and has a recessed water storage tank 52. As the flat mop head 3 moves downwards into the wringer bucket 12, the water storage tank 52 collects some of the water squeezed from the wiping material 4. As the flat mop head 3 moves upwards away from the wringer bucket 12, the flat mop head 3 causes the wringer plate 5 to flip in the opposite direction to the flat mop head 3, thus draining the water in the water storage tank 52 into the wastewater bucket 13. The system also includes a limiting structure 7 to restrict the oscillation angle of the wringer plate 5. During the downward movement of the flat mop head 3 into the wringer bucket 12, the wringer plate 5 flips forward to a first position and is blocked by the limiting structure 7.

[0055] The water purification tank 11 and the squeezing tank 12 are connected by a water supply channel D, the inlet of which is located at the bottom of the water purification tank 11 or the lower part of its surrounding structure. The water purification tank 11 has a first insertion part 111 on its side wall or bottom, with a first through hole 112 connecting the outside to its inner cavity. The squeezing tank 12 has a second insertion part 121 on its side wall, with a second through hole 122 connecting the outside to its inner cavity. The second insertion part 121 is inserted into the first through hole 112, which constitutes the water supply channel D; alternatively, the first insertion part 111 is inserted into the second through hole 122, which constitutes the water supply channel D.

[0056] The water supply channel D is controlled by switch 6. Moving switch 6 downwards closes the water supply channel D, while moving switch 6 upwards opens it. The mop cooperates with switch 6, causing the switch 6 to move downwards as the mop moves downwards. Switch 6 is elongated and is constrained to the inner wall of the wringer 12 by a ribbed guide structure 8. During the downward movement of switch 6, the ribbed guide structure 8 applies a force to switch 6 towards the water outlet end of the water supply channel D. The upper end 61 of switch 6 extends above the wringer 12 for operation. The upper end 61 of switch 6 has a groove or rib for operation, and the middle of switch 6 has a protruding linkage part 62 that cooperates with the downward-moving mop. The wringer 12 has a stop part 10 that blocks the downward movement of switch 6 to close the water supply channel D.

[0057] The top of the water purification tank 11 is closed. The water purification tank 11 consists of a tank body 11a with an open top and a lid 11b. The lid 11b is placed over the opening of the tank body 11a to form a seal. The lid 11b is provided with a water inlet 11d, and a plug 11e is provided at the water inlet 11d to seal it.

[0058] After the water in the squeezing bucket 12 has submerged the outlet end of the water supply channel D, the water supply to the squeezing bucket 12 is stopped. The water supply channel D also serves as an air inlet channel, allowing air to enter the space above the liquid surface of the clean water bucket 1a through the water supply channel D while water is being injected into the squeezing bucket 121b, until the water in the squeezing bucket 12 submerges the outlet end D2 of the water supply channel D. The water supply channel D is horizontally arranged, or it is inclined downwards from the inlet end D1 towards the outlet end D2, or at least the top end D1 of the inlet end of the water supply channel D is higher than the top end D2 of the outlet end.

[0059] There is a height distance H between the bottom of the water supply channel D and the bottom of the squeezing area 1b. The water level in the squeezing bucket 12 when it is above the outlet of the water supply channel D is the initial water level height h1. When the flat mop head is fully inside the squeezing bucket 12, the water level in the squeezing bucket 12 rises to the second water level height h2, and the height of the wiping material 4 is higher than the second water level height h2.

[0060] The purified water tank and the squeezing tank 12 are staggered vertically. A support member 9 is provided between the bottom of the purified water tank 11 and the inner bottom surface of the sewage tank 13. The support member 9 is a support column provided on the inner bottom surface of the sewage tank 13 and extending upward, or a support column provided on the bottom of the purified water tank 11 and extending downward, or a support column provided on the inner wall of the sewage tank 13 and extending inward to support the bottom of the purified water tank 11.

[0061] The working principle and process of this cleaning tool embodiment are as follows:

[0062] During cleaning, first fill the water tank 11 with clean water and seal the top of the water tank 11. Turn on the switch 6, and the water tank 11 supplies water to the squeezing bucket 12 through the water supply channel D. When the water in the squeezing bucket 12 has submerged the outlet D2 of the water supply channel D, the water tank 11 will stop supplying water to the squeezing bucket 12 due to the sealing of the top of the water tank 11 and atmospheric pressure. Therefore, the amount of water supplied each time is constant.

[0063] After water supply is complete, switch 6 is turned off. The flat mop head 3 enters the wringer 12. The water level in the wringer 12 is the initial water level h1 when it exceeds the outlet D2 of the water supply channel D. When the flat mop head 3 is fully inside the wringer 12, the water level in the wringer 12 rises to the second water level h2, and the height of the wiping material 4 is higher than the second water level h2. The flat mop head 3 is moved up and down, and the wiping plate 5 is used to squeeze and clean the wiping material 4. Each time, the wastewater squeezed off the wiping material 4 is transferred to the wastewater tank 13 through the water flow channel S1. As the flat mop head 3 moves downward into the wringer 12, the water in the return water channel S2 flows back to the wiping material 4, so that it can be absorbed by the wiping material 4 with low water content. Repeat this process several times until all the water in the wringer 12 is removed. Then, move the flat mop head 3 up and down a few more times, and the wringer 5 will thoroughly squeeze the water out of the wiped item 4. For the second wash, simply turn on the switch 6 again and repeat the above steps.

[0064] After several washes, the amount of water on the wiping material 4 is small, and the energy of the squeezed water is insufficient to transfer it to the sewage tank 13 through the first water transfer channel D1. The small amount of squeezed water will be stored in the water storage tank 52. The water in the water storage tank 52 can be discharged to the sewage tank 13 by swinging, or it can be discharged to the sewage tank 13 by setting a drain hole at the bottom of the water storage tank 52 to the sewage area.

[0065] In summary, this cleaning tool can automatically supply a fixed amount of water for each cleaning session, ensuring that the water used to wash the mop is clean each time, resulting in better cleaning effect and water conservation. The amount of water in one water tank 11 can be used to clean the mop multiple times with a fixed amount of clean water.
