Description

Flat mop cleaning tools Technical Field

[0001] This invention belongs to the technical field of cleaning tools, and in particular to a flat mop cleaning tool suitable for cleaning fiber cloth flat mops or foam cotton 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 protection focuses, 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 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. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to provide a flat mop cleaning tool that ensures that the water used to clean the mop is clean every time it is washed, and that the washing and wringing operations can be completed in the same location, in light of the above-mentioned existing technology.

[0010] The first technical solution adopted by the present invention to solve the above-mentioned technical problem is: a flat mop cleaning tool, comprising a cleaning bucket and a mop, the mop including a mop head rotatably connected to the lower end of the mop handle, the mop head being provided with a wiping agent; characterized in that: the cleaning bucket has independent clean water area, washing area and wastewater area, the cleaning bucket is provided with a first opening for the mop head to pass through, and a first squeezing component to squeeze the wiping agent, the first opening corresponding to the washing area, the mop head can enter the washing area after passing through the first opening, the clean water area and the washing area are connected by a water supply channel, the water supply channel being controlled by a switch to open and close; cleaning The bucket is equipped with a first water transfer channel to transfer the squeezed-out wastewater to the wastewater area. The operation of the mop head in the cleaning area is divided into two time periods. In the first time period, there is an appropriate amount of clean water in the cleaning area. The mop head is moved up and down several times, and the clean water in the cleaning area cleans the wiped object. During the operation, the water in the cleaning area is gradually discharged to the wastewater area through the first water transfer channel. The first wringing component squeezes the wiped object to complete the cleaning. In the second time period, the water in the cleaning area is basically discharged to the wastewater area. The mop head is moved up and down several times again, and the first wringing component squeezes the wiped object to complete the drying.

[0011] Preferably, after the water purification zone supplies a fixed amount of water to the cleaning zone via the water supply channel, the switch closes the water supply channel. This fixed water supply allows for a more accurate determination of how many cleaning uses a full water supply in the purification zone can provide.

[0012] To achieve automatic, quantitative water supply, a key improvement is the sealing of the top of the aforementioned water purification zone. Simultaneously, air enters the space above the liquid surface in the water purification zone through the water supply channel, continuing until the water in the cleaning zone surpasses the outlet or inlet of the water supply channel, at which point the water supply automatically stops. During cleaning, the switch is turned on, and the water purification zone supplies water to the cleaning zone via the water supply channel. Once the water in the cleaning zone surpasses the outlet of the water supply channel, the sealed top of the water purification zone, under atmospheric pressure, stops supplying water to the cleaning zone. Therefore, the amount of water supplied each time is constant, and the water supply automatically stops.

[0013] Preferably, there is a height distance between the water supply channel and the bottom of the cleaning zone. The smaller the height distance, the less water is needed to block the outlet of the water supply channel, allowing for more frequent water reuse in the cleaning zone. However, if too little water flows into the cleaning zone, it cannot guarantee sufficient immersion of the cleaning material, affecting the cleaning effect. To conserve water, preferably, the initial water level is when the water in the cleaning zone exceeds the outlet or inlet of the water supply channel. With the mop head fully inside the cleaning zone, the water level rises to a second water level, where the height of the cleaning material is higher than the second water level. The cleaning material above the second water level is not wetted; this portion can be wetted by water transferred from the return water channel.

[0014] As an improvement, a water inlet is provided at the top of the aforementioned water purification zone, and a cap is provided to seal the water inlet. The water inlet facilitates the filling of water into the water purification zone, while the cap ensures that the top of the water purification zone is sealed.

[0015] Furthermore, the cleaning zone includes a water return channel that redirects some of the water squeezed off the cleaning surface back to the surface. The water transferred through this channel can moisten the upper part of the surface on the mop head entering the cleaning zone, meaning the water in the cleaning zone can partially submerge the surface. This reduces the amount of water used in a single cleaning cycle, making this cleaning tool more water-efficient and environmentally friendly.

[0016] Preferably, as the mop head moves downward, the water returning from the water return transfer channel wets the object being wiped from bottom to top. This water return transfer channel ensures complete wetting of the object being wiped, as the mop head typically moves downward quickly, so most of the returning water wets the head end of the object.

[0017] Preferably, the aforementioned water return transfer channel is located above the first squeezing component. The first squeezing component has a baffle, or a baffle is provided on the component for mounting the first squeezing component, or a baffle is located above the cleaning area. A portion of the water squeezed off the wiping material is blocked by the baffle and then passes through the water return transfer channel to wet the wiping material again. Because the water return transfer channel is located above the first squeezing component, the water return path is shorter, allowing for faster return to the wiping material and wetting of the wiping material above the first squeezing component.

[0018] Preferably, the first wringing component is a wringing plate, and each of the baffles forms a water return transfer channel above the first wringing component. As the mop head moves downwards into the cleaning area, the water in the water return transfer channel is absorbed by the wiping material with a lower water content. The baffles can block some of the water squeezed off the wiping material, thus forming the water return transfer channel. Of course, the water return channel can also adopt other structural methods, but combining it with the wringing plate is more reasonable.

[0019] To further improve the system and ensure efficient transfer of water from the cleaning zone to the wastewater zone, the first wringing component features a recessed water storage tank. During the up-and-down movement of the mop head, this tank collects some of the water squeezed from the surface. After several washes, when the amount of water on the surface decreases and the squeezed water lacks sufficient energy to be transferred to the wastewater zone via the first water transfer channel, the small amount of water squeezed out is stored in the water storage tank. This water can then be discharged to the wastewater zone via the oscillating motion of the first wringing component. As the mop head moves upward away from the cleaning zone, it causes the first wringing component to rotate in the opposite direction, discharging the water from the storage tank away from the cleaning zone. Alternatively, a drain hole can be provided at the bottom of the storage tank to drain the water into the wastewater zone.

[0020] To enable the first wringing component to swing, the middle of its front and rear sides is pivotally mounted on the cleaning area. An edge on one side of the first wringing component is formed to scrape the object being wiped. The scraping edge and baffle are located on the left and right sides of the pivot, respectively. As the mop head moves downwards into the cleaning area, the scraping edge swings downwards, and the baffle swings upwards, ensuring that water in the return water transfer channel flows back to the object being wiped.

[0021] Further improvements include providing at least two positioning positions for the switch. In the first positioning position, the switch is in the open position, and in the second positioning position, the switch is in the closed position. This ensures that the lower end of the switch is clearly positioned in either the open or closed position, preventing the switch from easily actuating to the closed position when in the open position, and vice versa. Alternatively, a stepless positioning method can be used. The key is that when the switch is in either the open or closed position, the positioning device must apply a positioning force to the switch. This positioning force can be clamping force, frictional force, elastic force, or latching force, etc.

[0022] Preferably, the mop works in conjunction with the switch, so that the downward movement of the mop causes the switch to move in the direction of closing the water supply. The switch automatically turns off by the downward movement of the mop, eliminating the need for manual operation and creating a more rational design that links the mop to the switch.

[0023] Preferably, the switch is lowered to close the water supply channel, and raised to open the water supply channel. This makes operation more convenient.

[0024] To facilitate linkage with a mop, the switch is equipped with a linkage part that works in conjunction with the downward-moving mop.

[0025] In a further improvement, the aforementioned switch is constrained to the inner wall of the cleaning area 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, enabling the switch to better 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.

[0026] Furthermore, the cleaning zone is equipped with a positioning structure to hold the switch in an upward or downward position. This prevents the switch from moving easily and requires a certain amount of force to move it up or down.

[0027] To facilitate assembly and further improve the design, a mounting bracket is connected to the top opening of the outer barrel, and the first through-hole is located on the mounting bracket.

[0028] To meet the different needs of different customers for the degree of squeezing of the wiping material, the cleaning bucket is further improved by providing a second opening for the mop head to pass through. The second opening is located outside the cleaning area, and a second squeezing component is provided inside the second opening to squeeze the wiping material.

[0029] If the user feels the mop isn't sufficiently wrung out after washing in the cleaning area, they can detach the mop head from the first opening, insert it into the second opening, and move it up and down repeatedly. The second wringing component will then reciprocate and squeeze the surface, thoroughly removing the water. This further wringing is done in an area separate from and outside the cleaning area, without interference, resulting in a more effective wringing process compared to wringing within the cleaning area.

[0030] To ensure the wringing operation is completed in a separate area, as an improvement, the cleaning bucket also has a wringing zone independent of the clean water zone and the washing zone. The second opening corresponds to the wringing zone, and the mop head can enter the wringing zone after passing through the second opening. The independent wringing zone is beneficial for maintaining a basically water-free environment, allowing the wiped items to be squeezed out more thoroughly.

[0031] Further improvements include a second water transfer channel to transfer water squeezed off the wiped item by the second wringing component to the outside of the wringing area. The second water transfer channel ensures that water squeezed off the wiped item will not remain in the wringing area, resulting in better wringing effect of the mop head within the wringing area. A lifting protrusion can also be provided at the bottom of the wringing area so that even if a small amount of water flows into the wringing area, it will be located below the lifting protrusion and will not wet the wiped item at the bottom of the mop head.

[0032] Preferably, the second water transfer channel has a first channel extending forward and backward, and a second channel located on one side of the first channel and extending towards the sewage area, the second channel being connected to the first channel. The second channels on both sides enable rapid and efficient drainage.

[0033] As an improvement, the second channel is inclined downwards from the first channel towards the sewage area. This ensures that water drains smoothly through the second channel.

[0034] To make the operation of this cleaning tool more user-friendly, a linkage component for opening the switch is provided outside the first opening. Ideally, the linkage component can be triggered by a mop entering the second opening to open the switch. This allows the mop to pre-trigger the linkage component and open the switch during the wringing process, supplying water from the clean water zone to the washing zone for the next cleaning use, without requiring additional operation to open the switch.

[0035] To facilitate the linkage component being triggered by the mop, as an improvement, the linkage component includes a triggering component extending to the second through-hole. This triggering component is kinetically connected to the switch. The triggering component can be triggered by the mop entering the second through-hole, causing the triggering component to move and drive the switch upward to open the water supply channel.

[0036] Preferably, the triggering component is movable left and right. The triggering component has a connecting rod and a trigger head protruding outward from the connecting rod. The trigger head extends to a second through-hole, and the connecting rod is connected to the switch. The connecting rod moves towards the switch along with the trigger head, causing the switch to move upward. The aforementioned linkage components are rationally arranged and can move smoothly, making it easier to open the switch.

[0037] As a transmission connection method between the connecting rod and the switch, the connecting rod and the switch are connected by a groove-protrusion mating structure. The groove in the groove-protrusion mating structure is provided on one of the connecting rod and the switch, and the protrusion in the groove-protrusion mating structure is provided on the other of the connecting rod and the switch. The protrusion is inserted into the groove and can slide along the groove.

[0038] To facilitate the downward movement of the mop head and the left and right movement of the trigger head, the top surface of the trigger head has a sloping section.

[0039] Preferably, a contact wall is provided on one side of the second opening, which supports the mop head passing through the second opening. The starting position of the inclined section is located behind the contact wall. The contact wall can be a rib with intermittent protrusions, or an arc-shaped or circular protrusion. This fit ensures that the downward movement of the mop head can contact the inclined section, thereby ensuring that the downward movement of the mop head drives the triggering component to move laterally.

[0040] To facilitate assembly and further improve the design, a mounting bracket is connected to the top opening of the outer barrel, and the first and second through holes are located on the mounting bracket.

[0041] As a specific implementation of the clean water area, cleaning area, and wastewater area, the cleaning bucket includes an outer bucket, a first inner bucket, and a second inner bucket. The inner cavity of the outer bucket constitutes the wastewater area, the inner cavity of the first inner bucket constitutes the clean water area, and the inner cavity of the second inner bucket constitutes the cleaning area. The first inner bucket and the second inner bucket are at least partially installed inside the outer bucket.

[0042] As one specific implementation of the clean water zone, washing zone, wringing zone, and wastewater zone, the aforementioned cleaning bucket includes an outer bucket, a first inner bucket, and a second inner bucket. The first and second inner buckets are at least partially installed inside the outer bucket. The inner cavity of the outer bucket constitutes the wastewater zone, the inner cavity of the first inner bucket constitutes the clean water zone, and the inner cavity of the second inner bucket constitutes the washing zone. The outer bucket forms the exterior of both the clean water zone and the washing zone. A second opening corresponds to the inner cavity of the outer bucket, and the bottom of the outer bucket is provided with a support platform that supports the bottom of the mop head passing through the second opening. The inner cavity of the outer bucket constitutes the wringing zone.

[0043] As a second specific implementation of the clean water area, washing area, squeezing area, and wastewater area, the cleaning bucket includes an outer bucket, a first inner bucket, and a second inner bucket. The outer bucket is provided with a partition that divides the outer bucket into a squeezing area and a wastewater area. The first inner bucket and the second inner bucket are at least partially installed in the wastewater area of ​​the outer bucket. The inner cavity of the first inner bucket constitutes the clean water area, and the inner cavity of the second inner bucket constitutes the washing area.

[0044] To ensure a stable connection between the two inner tubs and facilitate assembly, the first and second inner tubs are fitted together to form a unit, which can be detached from the outer tub. This unit can be moved to the faucet for independent water filling and also facilitates cleaning of the outer tub.

[0045] To ensure that the first and second inner tubs do not easily sway relative to the outer tub during cleaning operations, as an improvement, the first inner tub has a first insertion part on its side wall or bottom, with a first water passage hole connecting the outside to its inner cavity. The second inner tub has a second insertion part on its side wall, with a second water passage hole connecting the outside to its inner cavity. The second insertion part is inserted into the first water passage hole, which constitutes the water supply channel; alternatively, the first insertion part is inserted into the second water passage hole, which constitutes the water supply channel. Furthermore, 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.

[0046] Compared with existing technologies, the advantages of this invention are as follows: During cleaning, the switch is turned on, and water from the clean water zone to the cleaning zone is supplied through the water supply channel; after the water supply is complete, the switch is turned off, and the mop head enters the cleaning zone through the first opening and moves up and down. The operation of the mop head in the cleaning zone is divided into two time periods. In the first time period, there is an appropriate amount of clean water in the cleaning zone. The mop head is moved up and down multiple times, and the clean water in the cleaning zone cleans the wiped object. During the operation, the water in the cleaning zone is gradually discharged to the wastewater zone through the first water transfer channel, and the first wringing component squeezes the wiped object to complete the cleaning. In the second time period, the water in the cleaning zone is basically discharged to the wastewater zone, and the mop head is moved up and down multiple times again, and the first wringing component squeezes the wiped object to complete the wringing. For the second cleaning, simply turn on the switch again and repeat the above steps. In summary, this cleaning tool can ensure that the water used to clean the mop is always clean water, and can complete the cleaning and wringing operations in the same location (cleaning zone), eliminating the need for an additional wringing zone, and allowing for a more compact cleaning bucket.

[0082] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0083] A flat mop cleaning tool includes a cleaning bucket 1 and a mop. The mop includes a mop head 3 rotatably connected to the lower end of a mop handle 2. The mop head 3 includes an adapter thereon. A wiping material 4 is provided on the mop head 3. The lower end of the wiping material 4 is sleeved or fastened to a 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. The wiping material 4 can be a fiber cloth or foam.

[0084] The cleaning tub has three independent zones: a clean water zone 1a, a washing zone 1b, and a wastewater zone 1c. The top of the clean water zone 1a is closed. The clean water zone 1a and the washing zone 1b are connected by a water supply channel E, which is positioned away from the back panel of the mop head 3 that enters the washing zone 1b. The outlet of the water supply channel E is located in the middle of the side wall of the second inner tub 13. The rear of the second inner tub 13 has a boss 133, and the outlet of the water supply channel E is located on the side wall of the boss 133. There is a height distance H between the water supply channel E and the bottom of the washing zone 1b, which is between one-sixth and two-thirds of the height of the washing zone 1b. The height of the washing zone 1a is greater than the maximum width of the water supply channel E. The volume of the clean water zone 1a is greater than twice the volume of the washing zone 1b when the water level reaches the outlet E2 of the water supply channel E.

[0085] The cleaning zone 1b is equipped with a first squeezing component 5a that squeezes the wiping material 4. The cleaning zone 1b has three upward channels: a switch channel 1b1 for the switch 6, a mop handle channel 1b2 for the mop handle, and a mop board channel 1b3 for the mop board. The water outlet E2 of the water supply channel E is connected to the switch channel 1b1. Liquid flowing out of the outlet E2 passes through the switch channel 1b1, then to the mop handle channel 1b2, and finally into the mop board channel 1b3. At least partially, one inner wall of the cleaning zone 1b is inclined, forming an flared shape from bottom to top. A water baffle 1b4 is provided within the cleaning zone 1b, adjacent to the back plate of the mop head 3.

[0086] A water inlet 1a1 is located at the upper part of the water purification zone 1a, and a cap 1a2 is used to seal the water inlet 1a1. The water supply channel E also serves as an air intake channel, allowing air to enter the space above the liquid surface in the water purification zone 1a through the water supply channel E while water is being supplied to the cleaning zone 1b, until the water in the cleaning zone 1b submerges the outlet E2 of the water supply channel E. The ratio of the first volume of the cleaning zone 1b to the second volume occupied by the cleaning zone 1b below the water supply channel E is 2 to 20.

[0087] It also includes a switch 6 for opening and closing the water supply channel E; the switch 6 moves downward to close the water supply channel E, and moves upward to open the water supply channel E. The mop cooperates with the switch 6, so that the downward movement of the mop drives the switch 6 downward. The switch 6 is elongated and is constrained to the inner wall of the cleaning area 1b by a ribbed guide structure 64. During the downward movement of the switch 6, the ribbed guide structure 64 applies a force to the switch 6 in the direction of approaching the water outlet end of the water supply channel E. The upper end of the switch 6 has a groove 61 or a rib for operation and extends above the cleaning area 1b. The middle part of the switch 6 has an outwardly protruding linkage part 62 that cooperates with the downward-moving mop. The cleaning area 1b has a stop part 10 that blocks the downward movement of the switch 6 to close the water supply channel E.

[0088] The cleaning zone 1b is equipped with a positioning structure for positioning the switch 6 in an upward or downward position. In the upward position, the switch 6 is in the open state, and in the downward position, the switch 6 is in the closed state. The positioning structure includes a positioning plate 6a fixed on the cleaning zone 1b. The positioning plate 6a has a sliding groove 6a1. The side wall of the sliding groove 6a1 has upper positioning points 6a2 and lower positioning points 6a3 that are spaced apart from each other. The switch 6 has a protruding positioning part 63 that enters the sliding groove 6a1 and can slide up and down. When the switch 6 moves upward, the positioning part 63 is located above the upper positioning point 6a2, and the upper positioning point 6a2 blocks the downward movement of the positioning part 63. When the switch 6 moves downward, the positioning part 63 is located below the lower positioning point 6a3, and the lower positioning point 6a3 blocks the upward movement of the positioning part 63.

[0089] The cleaning tank 1 is equipped with a first water transfer channel D1 for transferring the squeezed-out sewage to the sewage area 1c.

[0090] The inlet end of the water supply channel E is located at the bottom of the water purification zone 1a or at the lower part of its surrounding structure. The water supply channel E is horizontally positioned, or it is inclined downwards from the inlet end E1 towards the outlet end E2, or at least the top end E1 of the inlet end of the water supply channel E is higher than the top end E2. The height dimension h1 between the bottom and top of the water supply channel E is less than one-third of the distance h2 between the bottom of the water supply channel E and the top of the water purification zone 1a. The cross-sectional area of ​​the water supply channel E is greater than 50 square millimeters and less than 800 square millimeters.

[0091] In this embodiment, the cleaning tub 1 includes an outer tub 11, a first inner tub 12, and a second inner tub 13. The inner cavity of the outer tub 11 forms a wastewater zone 1c, and the inner cavity of the first inner tub 12 forms a clean water zone 1a. The top of the first inner tub 12 is open, and an observation cover 15, at least partially made of transparent material, is provided at the opening for sealing. The observation cover 15 is ultrasonically welded or fastened to the first inner tub 12. The inner cavity of the second inner tub 13 forms a cleaning zone 1b. The first inner tub 12 and the second inner tub 13 are at least partially installed inside the outer tub 11. The first inner tub 12 has raised reinforcing ribs 123 formed on its wall. The opening of the second inner tub 13 has an outwardly turned reinforcing flange 133, and the top of the reinforcing flange 133 has an upwardly extending water-blocking rib 134.

[0092] The first inner tub 12 has a first insertion part 121 on its side wall or bottom. The first insertion part 121 has a first water passage hole 122 that connects the outside to its inner cavity. The second inner tub 13 has a second insertion part 131 on its side wall. The second insertion part 131 has a second water passage hole 132 that connects the outside to its inner cavity. The second insertion part 131 is inserted into the first water passage hole 122, and the second water passage hole 132 constitutes the water supply channel E. Alternatively, the first insertion part 121 is inserted into the second water passage hole 132, and the first water passage hole 122 constitutes the water supply channel E.

[0093] The outer tub 11 is provided with a third limiting structure that limits the first inner tub 12 in the lateral and longitudinal directions. The third limiting structure includes an inner shoulder 112 on the inner wall of the outer tub 11, a first limiting part 113 that protrudes upward at the inner shoulder 112, and a second limiting part 123 that protrudes laterally on the first inner tub 12. The second limiting part 123 rests on the inner shoulder 112, and the first limiting part 113 forms a lateral obstruction to the second limiting part 123.

[0094] The first inner tub 12 and the second inner tub 13 are fitted together to form a unit. The second inner tub 13 is provided with a support rib 134 and a buffer pad 135. The height of the support rib 134 is higher than the height of the buffer pad 135, and the buffer pad 135 extends out of the outer bottom surface of the second inner tub 13. The first inner tub 12 and the second inner tub 13 are fixed to the connecting component 10a by screws or snaps, and the connecting component 10a is installed on the outer tub 11.

[0095] A mounting bracket 9 is detachably connected to the top opening of the outer tub 11, with one side of the mounting bracket 9 abutting against the clean water tub 12. The mounting bracket 9 has a squeegee 91 for the mop head 3 to enter and communicate with the inner cavity of the washing tub 13, and the first wringing component 5a is located inside the mounting bracket 9. The mounting bracket 9 is provided with a sliding slider 92, and one of the slider 92 and the corresponding inner wall of the outer tub 11 has at least two side-protruding locking parts 9a, and the other of the slider 92 and the corresponding inner wall of the outer tub 11 has at least two locking grooves 9b. The locking parts 9a slide into the locking grooves 9b to detachably connect the mounting bracket 9 to the top opening of the outer tub 11.

[0096] The cleaning tank 1 is also equipped with a second water transfer channel D2 for transferring the squeezed-off wastewater to the cleaning area 1b. The first water transfer channel D1 is located above the second water transfer channel D2. The water on the wiping material 4 squeezed off by the first squeezing member 5a flows to the second water transfer channel D2 and returns to the cleaning area 1b via the same or similar path.

[0097] The first squeezing component 5a is a squeezing plate. The first squeezing component 5a has an upwardly extending baffle 51, which forms the second water transfer channel D2 above the first squeezing component. During the downward movement of the mop head 3 into the cleaning area 1b, the water in the second water transfer channel D2 can be absorbed by the wiping material 4, which has a relatively low water content. The first squeezing component 5a has a recessed water storage tank 52; during the up-and-down movement of the mop head 3 for cleaning, the water storage tank 52 can collect some of the water squeezed off the wiping material 4. Some of the water squeezed out by the downward movement of the mop head 3 flows outward through the first water transfer channel D1, and some water enters the water storage tank 52. At least during one pulling and squeezing process, the amount of water flowing outward is greater than the amount of water entering the water storage tank 52.

[0098] The water level in the cleaning zone 1b, when it exceeds the outlet of the water supply channel E, is the initial water level S1. The initial water level S1 is one-quarter to one-half the height of the mop head 3 when it is in the cleaning state. When the mop head 3 is fully inside the cleaning zone 1b, the water level rises to the second water level S2, and the height of the wiping material 4 is higher than the second water level S2. The second water level S2 is greater than or equal to two-thirds of the height of the wiping material 4.

[0099] The first wringing component 5a can swing. As the mop head 3 moves upward away from the cleaning area 1b, the mop head 3 drives the first wringing component 5a to flip in the opposite direction to the mop head 3, discharging the water in the water storage tank 52 into the sewage area 1c. The middle of the front and rear sides of the first wringing component 5a is pivotally mounted on or above the second inner tub 13. The edge of one side of the first wringing component 5a is formed to squeeze and scrape the wiping material 4. The squeezing edge and the baffle are located on the left and right sides of the pivot, respectively.

[0100] It also includes a first limiting structure that limits the swing angle of the first wringing component 5a. As the mop head 3 moves downward into the cleaning area 1b, the first wringing component 5a flips forward to a first position and is blocked by the first limiting structure. The first limiting structure provides support for the first wringing component 5a.

[0101] The second inner tub 13 is provided with a brush strip 7, and the lower part of the mounting frame 9 is provided with a relief groove 93 for the brush strip 7 to enter. The two ends of the brush strip 7 abut against the side wall of the relief groove 93 to limit the mounting frame 9.

[0102] The working principle and process of this cleaning tool embodiment are as follows:

[0103] As shown in Figures 1-5, during cleaning, clean water is first injected into the clean water zone 1a, and the top of the clean water zone 1a is sealed. Switch 6 is turned on, and the clean water zone 1a supplies water to the cleaning zone 1b through the water supply channel E. When the water in the cleaning zone 1b has submerged the outlet E2 of the water supply channel E, the clean water zone 1a stops supplying water to the cleaning zone 1b due to the sealing of the top of the clean water zone 1a and the action of atmospheric pressure. Therefore, the amount of water supplied each time is constant. The quantitative water volume entering the cleaning zone 1b is the volume defined by the horizontal height corresponding to the top of the water supply channel E and the bottom of the cleaning zone 1b.

[0104] As shown in Figures 6-10, after the water supply is completed, switch 6 is turned off, and mop head 3 enters the cleaning zone 1b. The water level in cleaning zone 1b is the initial water level S1 when it exceeds the outlet E2 of the water supply channel E. When mop head 3 is fully inside cleaning zone 1b, the water level in cleaning zone 1b rises to the second water level S2, and the height of the wiping object 4 is higher than the second water level S2. Moving mop head 3 up and down, the first squeezing component 5a is used to squeeze and clean the wiping object 4. Each time the wastewater squeezed off the wiping object 4 is transferred to the wastewater zone 1c through the first water transfer channel D1, the wiping object 4 needs to be moved up and down at least twice by the mop handle for most of the liquid from the first inner tub 12 to be transferred from the second inner tub 13 to the outer tub 11.

[0105] As the mop head 3 moves downwards into the cleaning zone 1b, water in the second water transfer channel D2 flows back to the wiping surface 4. As the mop head 3 moves downwards, some of the water squeezed off the wiping surface 4 is absorbed from bottom to top through the second water transfer channel D2, allowing it to be absorbed by the relatively dry wiping surface 4. This process is repeated until all the water in the cleaning zone 1b is transferred. After a few more up-and-down movements of the mop head 3, the first wringing component 5a can thoroughly squeeze out the water from the wiping surface 4. During at least part of the cleaning process, water is transferred simultaneously from the first water transfer channel to the wastewater chamber and from the second water transfer channel D2 to the cleaning zone, with the water flow rate of the first water transfer channel D1 being greater than that of the second water transfer channel D2. For the second cleaning, simply turn on the switch 6 again and repeat the above steps.

[0106] 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 area 1c via 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 area 1c by swinging, or it can be discharged to the sewage area 1c by setting a drain hole at the bottom of the water storage tank 52.

[0107] 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 tank of clean water can be used to clean the mop multiple times.

[0108] Figure 18 shows the second embodiment of the present invention.

[0109] The difference between this embodiment and the first embodiment is that the cleaning zone 1b is provided with a drain outlet 1b6 for discharging wastewater from the cleaning zone 1b to the wastewater zone 1c. The drain outlet 1b6 is equipped with an opening and closing element 1b5, and the drain outlet 1b6 constitutes the first water transfer channel D1. During cleaning, the opening and closing element 1b5 is in the closed state, the first squeezing component 5a contacts the wiping material 4, and the squeezed-off wastewater is discharged back to the cleaning zone 1b. When the material is squeezed dry, the opening and closing element 1b5 is in the open state, and the wastewater is discharged from the drain outlet 1b5 to the wastewater zone 1c.

[0110] Figures 19 to 34 show the third embodiment of the present invention.

[0111] The difference between this embodiment and the first rod embodiment is that the cleaning bucket 1 also has a wringing area 1d independent of the clean water area 1a and the washing area 1b. A wringing opening 94 for the mop head 3 to pass through is provided above the wringing area 1d. The wringing opening 94 is mounted on the mounting bracket 9, and a second wringing component 5b is provided on the wringing opening 94 to squeeze the wiping material 4. A third water transfer channel D3 is also included to transfer the water squeezed off the wiping material 4 by the second wringing component 5b to the wastewater area 1c. The second wringing component 5b is located higher than the first wringing component 5a.

[0112] A linkage component 8 for opening the switch 6 is provided outside the cleaning area 1b. The linkage component 8 can be triggered by a mop entering the wringer 94 to open the switch 6. The linkage component 8 includes a triggering component; the triggering component can move left and right, and has a connecting rod 81 and a trigger head 82 protruding outward from the connecting rod 81. The connecting rod 81 is connected to the switch 6, and the connecting rod 81 moves towards the switch with the trigger head 82, causing the switch 6 to move upward. The connecting rod 81 and the switch 6 are connected by a groove-protrusion fitting structure. The groove 9a in the groove-protrusion fitting structure is provided on one of the connecting rod 81 and the switch 6, and the protrusion 9b in the groove-protrusion fitting structure is provided on the other of the connecting rod 81 and the switch. The protrusion 9b is inserted into the groove 9a and can slide along the groove 9a. The top surface of the trigger head 82 has a slope section 821. A contact wall 941 is provided on one side of the wringer opening 94. The contact wall 941 can support the mop head 3 passing through the wringer opening 94. The starting position of the inclined section 821 is located behind the contact wall 941.

[0113] The third water transfer channel D3 has a first channel D31 extending forward and backward on both sides. The third water transfer channel D3 also has a second channel D32 located on both sides of the first channel D31 and extending towards the sewage zone 1c. The second channel D32 is connected to the first channel D31. The second channel D32 is inclined downward from the first channel D31 towards the sewage zone 1c.

[0114] The cleaning tub 1 includes an outer tub 11, a first inner tub 12, and a second inner tub 13. The outer tub is provided with a partition 14, which divides the outer tub 11 into a squeezing area 1d and a wastewater area 1c. The first inner tub 12 and the second inner tub 13 are at least partially installed in the wastewater area 1c of the outer tub 11. The inner cavity of the first inner tub 12 constitutes the clean water area 1a, and the inner cavity of the second inner tub 13 constitutes the cleaning area 1b.

[0115] Of course, the cleaning bucket can also have the following structure: the cleaning bucket 1 includes an outer bucket 11, a first inner bucket 12, a second inner bucket 13 and a third inner bucket, the first inner bucket 12, the second inner bucket 13 and the third inner bucket are at least partially installed in the outer bucket 11, the inner cavity of the first inner bucket 12 constitutes the clean water zone 1a, the inner cavity of the second inner bucket 13 constitutes the washing zone 1b, the inner cavity of the third inner bucket constitutes the squeezing zone 1c, and the outer bucket 11 constitutes the wastewater zone 1d.

[0116] Figure 35 shows the fourth embodiment of the present invention.

[0117] The difference between this embodiment and the first embodiment is that there is no independent squeezing area. The cleaning bucket 1 includes an outer bucket 11, a first inner bucket 12 and a second inner bucket 13. The first inner bucket 12 and the second inner bucket 13 are at least partially installed inside the outer bucket 11 of the outer bucket 11. The inner cavity of the first inner bucket 12 constitutes the water purification area 1a, and the inner cavity of the second inner bucket 13 constitutes the cleaning area 1b. The outer bucket 11 constitutes the exterior of the water purification area 1a and the cleaning area 1b. The second opening 6b corresponds to the inner cavity of the outer bucket 11. The bottom of the outer bucket 11 is provided with a support platform 111 that supports the bottom of the mop head 3 passing through the second opening 6b.

[0118] Because the support platform 111 is raised inside the outer tub 11, the area inside the outer tub 11 below the support platform 111 forms a true wastewater storage area. Water transferred through the second water transfer channel D2 via the mop head 3 through the second opening 6b flows into the area inside the outer tub 11 below the support platform 111, thereby completing further squeezing. The second opening 6b and the support platform 111 constitute a squeezing area similar to that in the first embodiment.

[0119] It should be noted that in the description of this embodiment, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.
