Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tools, and in particular to a cleaning tool based on a mop cleaning bucket 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 cleaning tool based on a mop cleaning bucket that ensures that the water used to wash the mop is clean every time, in light of the existing technology.

[0010] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning tool based on a mop cleaning bucket, 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 has a clean water area, a washing area and a wastewater area that are independent of each other, the clean water area and the washing area are at least partially located in the wastewater area, the middle part of the clean water area and the washing area are connected by a water supply channel, the washing area is provided with a squeezing component that squeezes the wiping agent, and also includes a switch for opening and closing the water supply channel; the cleaning bucket is provided with a first water transfer channel for transferring the squeezed wastewater to the wastewater area.

[0011] Preferably, the top of the water purification zone is sealed, and 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 the water in the purification zone to be used more frequently. Of course, if too little water flows into the cleaning zone, it cannot guarantee that the water will be sufficient to submerge the items being wiped, affecting the cleaning effect. The height distance is between one-sixth and two-thirds of the height of the cleaning zone. During cleaning, the switch is turned on, and the purification zone supplies water to the cleaning zone through the water supply channel. Once the water in the cleaning zone has submerged the outlet of the water supply channel, due to the sealed top of the purification zone and atmospheric pressure, the purification zone stops supplying water to the cleaning zone. Therefore, the amount of water supplied each time is constant.

[0012] Preferably, the inlet of the water supply channel is located at the bottom of the water purification zone or at the lower part of the surrounding structure. The inlet of the water supply channel should be located as close as possible to the bottom of the squeezing area to ensure that the water in the purification zone is fully drained, resulting in high water purification efficiency.

[0013] Preferably, the water supply channel is horizontally arranged, or it is inclined downwards from the inlet end to the outlet end, or at least the top of the inlet end of the water supply channel is higher than the top of the outlet end. This facilitates air entry into the clean water area when the water supply channel drains water into the cleaning area, ensuring that water can be quickly discharged from the water supply channel.

[0014] To ensure the drainage speed of the water supply channel while avoiding excessive total drainage volume in a single operation, preferably, the height between the bottom and top of the water supply channel is less than one-third of the distance between the bottom of the water supply channel and the top of the clean water area. More preferably, it is about one-tenth.

[0015] To achieve a novel cleaning and wringing operation, the aforementioned cleaning area is equipped with a drain outlet for discharging wastewater from the cleaning area to the wastewater area. This drain outlet has an opening and closing element, forming the first water transfer channel. Opening the drain outlet drains all the water from the cleaning area. Then, moving the mop up and down causes the wiping material and the wringing component to squeeze out water directly from the drain outlet of the cleaning area. Specifically, during cleaning, the opening and closing element is in the closed state, the wringing component contacts the wiping material, and the squeezed wastewater is discharged back into the cleaning area, ensuring a constant supply of water for cleaning. During wringing, the opening and closing element is in the open state, and wastewater flows from the drain outlet to the wastewater area.

[0016] If the cross-sectional area of ​​the water supply channel is too small, the drainage speed will be low and the air intake speed will also be low; if it is too large, the single discharge volume will be too large, and the water in the clean water area will be filled in one time, resulting in too few cleaning times. Therefore, as a preferred option, the cross-sectional area of ​​the above-mentioned water supply channel is greater than 50 square millimeters and less than 800 square millimeters.

[0017] As a rotation, the aforementioned clean water zone and rinsing zone are at least partially located within the wastewater zone. This allows for a smaller overall volume of the cleaning tank; preferably, all or most of the clean water zone and rinsing zone are located within the wastewater zone.

[0018] As a specific implementation of the cleaning area and wastewater area, the aforementioned cleaning tank includes an outer tank, a first inner tank, and a second inner tank. The inner cavity of the outer tank constitutes the wastewater area, the inner cavity of the first inner tank constitutes the clean water area, and the inner cavity of the second inner tank constitutes the cleaning area. The first and second inner tanks are at least partially installed inside the outer tank. The outer tank, the first inner tank, and the second inner tank are independent components, which facilitates manufacturing. During assembly, it is only necessary to fix the first and second inner tanks into the outer tank. Alternatively, the cleaning area and the clean water area can be directly separated from each other inside the outer tank by a partition.

[0019] To ensure that the first and second inner tubs do not easily wobble 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 through hole communicating with the outside and its inner cavity. The second inner tub has a second insertion part on its side wall, with a second through hole communicating with the outside and its inner cavity. The second insertion part is inserted into the first through hole, which forms the water supply channel; alternatively, the first insertion part is inserted into the second through hole, which forms 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.

[0020] In a further improvement, a support component is provided between the bottom of the first inner tub and the inner bottom surface of the outer tub. This support component can be a support column located on the inner bottom surface of the outer tub and extending upwards, or a support column located on the bottom of the first inner tub and extending downwards, or a support column located on the inner wall of the outer tub and extending inwards to support the bottom of the first inner tub. Because the first and second inner tubs are arranged in a staggered manner, the support component provides support for the first inner tub, thereby more stably fixing the first inner tub inside the outer tub.

[0021] 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.

[0022] Preferably, the aforementioned water supply channel also functions as an air intake channel, allowing air to enter the space above the liquid surface in the clean water zone simultaneously with water being supplied to the cleaning zone, until the water in the cleaning zone submerges the outlet of the water supply channel. This better utilizes atmospheric pressure. Once the water in the cleaning zone submerges the outlet of the water supply channel, water supply to the cleaning zone ceases. When the water in the cleaning zone does not submerge the outlet of the water supply channel, and the switch is open, water from the clean water zone automatically supplies water to the cleaning zone. At the same time, air enters the space above the effective liquid surface in the clean water zone through the water supply channel, ensuring smooth water supply without the need for an additional air intake valve, resulting in a simpler structure. Alternatively, a one-way air intake valve could be installed in another location in the clean water zone, but this would complicate the structure.

[0023] Alternatively, a one-way air inlet valve may be provided on the wall or bottom of the aforementioned water purification zone, or on the cover or an associated third component, the one-way air inlet valve allowing only air from the outside to enter the space above the liquid surface of the water purification zone.

[0024] Alternatively, the bottom of the first inner tank is provided with a water inlet, and a one-way valve is installed at the water inlet. The water inlet is detachably installed at the water inlet end of the water supply channel, and the water inlet end of the water supply channel is provided with a push rod to open the one-way valve. Similar to the principle of a water dispenser tank, this makes it convenient to remove the first inner tank for water filling.

[0025] Furthermore, the cleaning bucket is equipped with a second water transfer channel to transfer the squeezed-out wastewater to the washing area. This allows the water transferred to the washing area via the second water transfer channel to only partially submerge the items being wiped on the mop head, thus reducing the amount of water used in a single wash and making this cleaning tool more water-efficient and environmentally friendly.

[0026] The two water transfer channels can be formed by the following structure: a diversion component is provided at the top of the cleaning area. This diversion component divides the water squeezed out from the wiping material into two parts. One part of the water flows to the sewage area to form the first water transfer channel, and the other part flows back to the wiping material to form the second water transfer channel. Of course, the diversion component can also be the same as the squeezing component.

[0027] Furthermore, the aforementioned wringing component is a wringing plate, and the wringing component is equipped with upwardly extending baffles. These baffles form a second water transfer channel above the wringing component. As the mop head moves downwards into the cleaning zone, the water in the second water transfer channel can be absorbed by the less moist cleaning material. The baffles can block some of the water squeezed off the cleaning material, thus forming the second water transfer channel. The water in the second water transfer channel flows back and can be absorbed by the less moist cleaning material. This means that the water in the cleaning zone can partially submerge the cleaning material, resulting in less water being used in a single cleaning cycle, making this cleaning tool more water-saving and environmentally friendly.

[0028] To further improve the process of transferring water from the cleaning area to the wastewater area, the aforementioned water-squeezing component has a recessed water storage tank. During the up-and-down movement of the mop head for cleaning, the water storage tank can collect some of the water squeezed off the wiping surface. After several washes, when the amount of water on the wiping surface is small and the energy of the squeezed water is insufficient to transfer it to the wastewater area via the first water transfer channel, the small amount of squeezed water will be stored in the water storage tank. The water in the water storage tank can be discharged to the wastewater area by swinging, or it can be discharged to the wastewater area through a drain hole at the bottom of the water storage tank.

[0029] To conserve water, preferably, the initial water level in the cleaning zone is when the water level exceeds the outlet of the water supply channel. With the mop head fully inside the cleaning zone, 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 second water transfer channel.

[0030] To quickly drain the water in the water storage tank to the sewage area, as an improvement, the aforementioned wringing component can swing. As the mop head moves upward away from the cleaning area, the mop head drives the wringing component to rotate in the opposite direction to the mop head, thereby draining the water in the water storage tank to the sewage area.

[0031] To enable the oscillation of the wringing component, the middle of the front and rear sides of the wringing component is pivotally mounted on or above the second inner tub. One edge of the wringing component is formed to scrape the wiping material. The scraping edge and the baffle are located on the left and right sides of the pivot, respectively. As the mop head moves downwards into the cleaning zone, the scraping edge oscillates downwards, and the baffle oscillates upwards, ensuring that water in the transition clean water zone flows back to the wiping material.

[0032] To ensure that the wringing component swings within a suitable angle range, a first limiting structure is included to limit the swing angle of the wringing component. During the downward movement of the mop head into the cleaning area, the wringing component flips forward to a first position and is blocked by the first limiting structure. If the forward flip angle is too large, water in the water storage tank may be discharged into the cleaning area. Therefore, the goal is to ensure that water in the water storage tank is not discharged into the cleaning area, but rather that as much water as possible is discharged into the wastewater area.

[0033] Preferably, the first limiting structure provides support for the dewatering component. Alternatively, it can provide support for the pivot.

[0034] Preferably, the ratio of the first volume of the cleaning zone to the second volume occupied by the cleaning zone below the water supply channel is 2 to 20. The optimal ratio is 4 to 6, where the ratio represents how many times the wiped items can be cleaned with the clean water in one tank of the cleaning zone.

[0035] Alternatively, the aforementioned switch can be turned on or off by rotating or moving horizontally.

[0036] Preferably, the switch moves downward to close the water supply channel, and moves upward to open the water supply channel. The mop works in conjunction with the switch, causing the switch to move downward as the mop moves downward. This structure automatically closes the switch by moving the mop downward, eliminating the need for manual closing and creating a more rational design that is linked to the mop.

[0037] 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.

[0038] To facilitate the user in turning on the switch, the upper end of the switch is provided with a groove or rib for operation.

[0039] To facilitate linkage with a mop, the switch is equipped with a linkage part that works in conjunction with the downward-moving mop.

[0040] To ensure that the switch does not move further after it has been lowered into position, the cleaning area is equipped with a stop that blocks the switch when it is lowered to close the water supply channel.

[0041] To prevent the first inner tub from swaying relative to the outer tub, as an improvement, the outer tub is provided with a third limiting structure to limit the first inner tub in the lateral and longitudinal directions.

[0042] Preferably, the aforementioned third limiting structure includes an inner shoulder blade on the inner wall of the outer barrel, a first limiting part protruding upward at the inner shoulder blade, and a second limiting part protruding laterally on the first inner barrel. The second limiting part rests on the inner shoulder blade, and the first limiting part forms a lateral obstruction to the second limiting part. The aforementioned third limiting structure has the advantages of simple structure and reliable limiting.

[0043] 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.

[0044] As an improvement, the aforementioned unit can be installed separately from the outer tank. Water can be added separately via the tap, which also facilitates cleaning of the outer tank.

[0045] The cleaning area described above is provided with at least two upward passages: a switch passage for the switch to pass through or a mop handle passage for the mop handle to pass through, and a mop board passage for the mop head to pass through.

[0046] Preferably, the cleaning area is provided with three upward channels: a switch channel for the switch to pass through, a mop handle channel for the mop handle to pass through, and a mop board channel for the mop board to pass through.

[0047] Preferably, the width of the aforementioned switch channel or the mop handle channel is smaller than the width of the mop board channel for the mop head. This reduces unnecessary volume and saves water.

[0048] Preferably, the outlet of the water supply channel is connected to the switch channel. The liquid flowing out of the outlet passes through the switch channel, then the mop handle channel, and finally into the mop board channel. This channel arrangement is reasonable and the structure is more compact.

[0049] As an improvement, the outer tub is equipped with a stop to limit the lower half of the second inner tub. The stop can be located on the inner bottom wall or inner side wall of the outer tub to prevent the second inner tub from shaking.

[0050] Preferably, the water supply channel is positioned away from the back panel of the mop head that enters the washing area. This makes the structure more compact; placing the water supply channel on the front or side would increase the area of ​​the bucket.

[0051] Preferably, the outlet of the water supply channel is located in the middle of the side wall of the second inner tub; the rear of the second inner tub has a boss, and the outlet of the water supply channel is located on the side wall of the boss. The position of the boss can form a channel for the mop handle to enter, constraining the mop handle and reducing excessive space in the washing area that is not used for washing the mop.

[0052] To prevent damage to the second inner tub from direct impact when the mop is used for cleaning, the second inner tub is further improved by providing support ribs and a cushioning pad. The height of the support ribs is higher than the height of the cushioning pad, and the cushioning pad extends out of the outer bottom surface of the second inner tub.

[0053] In a further improvement, the first and second inner tubs are fixed to the connecting component using screws or clips, and the connecting component is installed on the outer tub. During assembly, the two inner tubs can be pre-installed on the connecting component to ensure their relative positions are fixed, and then the connecting component can be fixed inside the outer tub, making assembly more convenient.

[0054] To ensure that even with a small amount of water, the highest water level in the cleaning zone rises as much as possible after the mop enters, at least one inner wall of the cleaning zone is partially inclined, so that the cleaning zone forms an flared shape from bottom to top.

[0055] To facilitate assembly and further improve the design, a mounting bracket is detachably connected to the top opening of the outer tub. The mounting bracket has a slot for the mop head to enter and communicate with the inner cavity of the second inner tub. The wringing component is located within the mounting bracket. The wringing component can be pre-installed on the mounting bracket, and then the mounting bracket can be installed on the outer tub. The slot on the mounting bracket provides restraint for the mop head's entry. The internal space of the mounting bracket can be considered part of the washing area.

[0056] To facilitate quick and easy installation of the mounting bracket onto the outer tub, the mounting bracket is further improved by incorporating a sliding slider. One of the slider and the corresponding inner wall of the outer tub has at least two protruding locking portions, while the other has at least two locking slots. The locking portions slide into the locking slots, detachably connecting the mounting bracket to the top opening of the outer tub. Alternatively, the mounting bracket can be secured using other methods, such as fasteners, welding, or snap-fit ​​connections.

[0057] As an improvement, one side of the mounting bracket abuts against the first inner tub. The mounting bracket serves to restrain the first inner tub.

[0058] To better clean the items being wiped, the second inner tub is equipped with bristle strips. These bristle strips facilitate the removal of hair and other dirt from the items. A recessed groove is provided below the mounting bracket for the bristle strips to enter. The two ends of the bristle strips abut against the sidewalls of the recessed groove to limit the movement of the mounting bracket. Additionally, the bristle strips also serve to constrain the mounting bracket.

[0059] To prevent water from splashing upwards out of the cleaning area when the mop head is lowered within the cleaning area, a water baffle is provided in the cleaning area, and the water baffle is located adjacent to the back plate of the mop head.

[0060] The second inner tub has an opening through which the mop head, mop handle, and switch can all pass.

[0061] When the mop head is rotated to a squeezing state, the mop head and the wringing component move vertically relative to each other, squeezing the wiping material once. The water supply channel is positioned away from the mop head.

[0062] When the mop handle moves the wiping material up and down and squeezes against the wringer, the wiping material does not come into contact with the baffle.

[0063] The switch is located between the water purification area and the water squeezing component.

[0064] As the mop moves downwards, the protrusion, groove, or connecting part of the switch comes into contact with the mop, causing the switch to move or rotate and shut off the water supply.

[0065] 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.

[0066] Preferably, the positioning structure includes a positioning plate fixed to the cleaning area, with a groove on the positioning plate. The sidewall of the groove has upper positioning points and lower positioning points spaced apart from each other. The switch has a protruding positioning part that enters the groove and can slide up and down. When the switch moves upward, the positioning part is above the upper positioning point, which blocks the downward movement of the positioning part. When the switch moves downward, the positioning part is below the lower positioning point, which blocks the upward movement of the positioning part. This positioning structure not only has a positioning function but also acts as a guide, achieving positioning through friction, eliminating the need for additional elastic components.

[0067] Compared with existing technologies, the advantages of this invention are as follows: During cleaning, turning on the switch allows the clean water zone to supply water to the cleaning zone via the water supply channel; after the water supply is complete, turning off the switch allows the mop head to enter the cleaning zone and move up and down, using the squeezing component to scrape and clean the object being wiped. Each time wastewater is squeezed from the object, it is transferred to the wastewater zone via the first water transfer channel. This process is repeated multiple times until all water in the cleaning zone is removed. A few more up-and-down movements of the mop head thoroughly squeeze out the water from the object. For the second cleaning, simply turn on the switch again and repeat the above steps. In summary, this cleaning tool ensures that only clean water is used each time the mop is washed, resulting in better cleaning performance and water conservation. One tank of clean water can provide enough water for multiple quantitative cleanings of the mop. Attached Figure Description

[0086] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0087] like Figures 1-17 The figure shown is a preferred embodiment of the present invention.

[0088] A cleaning tool based on a mop cleaning bucket 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. The mop head 3 is provided with a wiping material 4, which can be a fiber cloth or foam.

[0089] 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 1d, 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 1d 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 1d is located on the side wall of the boss 133. There is a height distance H between the water supply channel 1d 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 cleaning zone 1b is equipped with a squeezing component 5 that presses the wiping material 4. The cleaning zone 1b has three upward-facing 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 1d2 of the water supply channel 1d is connected to the switch channel 1b1. Liquid flowing out of the outlet 1d2 passes through the switch channel 1b1, then the mop handle channel 1b2, and finally flows 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.

[0090] The upper part of the water purification zone 1a is provided with a water inlet 1a1, and a cap 1a2 is provided to seal the water inlet 1a1. The water supply channel 1d also serves as an air inlet channel, so that while water is being injected into the cleaning zone 1b through the water supply channel 1d, air enters the space above the liquid surface in the water purification zone 1a through the water supply channel 1d until the water in the cleaning zone 1b submerges the outlet end 1d2 of the water supply channel 1d. 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 1d is 2 to 20.

[0091] It also includes a switch 6 for opening and closing the water supply channel 1d; the switch 6 moves downward to close the water supply channel 1d, and moves upward to open the water supply channel 1d. 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 1d. 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 1d.

[0092] The cleaning zone 1b is equipped with a positioning structure for positioning the switch 6 in an upward or downward position. The positioning structure includes a positioning plate 6a fixed to 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.

[0093] The cleaning tank 1 is equipped with a first water transfer channel D1 for transferring the squeezed-out sewage to the sewage area 1c.

[0094] The inlet end of the water supply channel 1d is located at the bottom of the water purification area 1a or at the lower part of its surrounding structure. The water supply channel 1d is horizontally positioned, or it is inclined downwards from the inlet end 1d1 towards the outlet end 1d2, or at least the top end 1d1 of the inlet end of the water supply channel 1d is higher than the top end 1d2. The height dimension h1 between the bottom and top of the water supply channel 1d is less than one-third of the distance h2 between the bottom of the water supply channel 1d and the top of the water purification area 1a. The cross-sectional area of ​​the water supply channel 1d is greater than 50 square millimeters and less than 800 square millimeters.

[0095] 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 constitutes the sewage zone 1c, the inner cavity of the first inner tub 12 constitutes the clean water zone 1a, and the inner cavity of the second inner tub 13 constitutes the cleaning zone 1b. The first inner tub 12 and the second inner tub 13 are at least partially installed inside the outer tub 11.

[0096] The first inner tub 12 has a first insertion part 121 on its side wall or bottom, and the first insertion part 121 has a first through hole 122 that connects to the outside and its inner cavity. The second inner tub 13 has a second insertion part 131 on its side wall, and the second insertion part 131 has a second through hole 132 that connects to the outside and its inner cavity. The second insertion part 131 is inserted into the first through hole 122, and the second through hole 132 constitutes the water supply channel 1d. Alternatively, the first insertion part 121 is inserted into the second through hole 132, and the first through hole 122 constitutes the water supply channel 1d.

[0097] The outer tub 11 is provided with a third limiting structure that limits the first inner tub 12 in both 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.

[0098] 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 7 by screws or snaps. The connecting component 7 is installed on the outer tub 11.

[0099] 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 first inner tub 12. The mounting bracket 9 has a spout 91 for the mop head 3 to enter and communicate with the inner cavity of the second inner tub 13, and a wringing component 5 is located within the mounting bracket 9. The mounting bracket 9 has a sliding slider 92. One of the slider 92 and the corresponding inner wall of the outer tub 11 has at least two side-protruding locking portions 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 portions 9a slide into the locking grooves 9b, detachably connecting the mounting bracket 9 to the top opening of the outer tub 11.

[0100] The cleaning tank 1 is also equipped with a second water transfer channel D2 for transferring the scraped-off wastewater to the cleaning area 1b.

[0101] The wringing component 5 is a wringing plate, and it has an upwardly extending baffle 51. The baffle 51 forms a second water transfer channel D2 above the wringing component. As the mop head 3 moves downward 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 wringing component 5 has a recessed water storage tank 52; during the up-and-down cleaning process of the mop head 3, the water storage tank 52 can catch some of the water squeezed off the wiping material 4.

[0102] The initial water level S1 is the water level in the cleaning zone 1b when it exceeds the outlet of the water supply channel 1d. When the mop head 3 is fully inside the cleaning zone 1b, the water level in the cleaning zone 1b rises to the second water level S2. The height of the wiping material 4 is higher than the second water level S2.

[0103] The wringing component 5 is oscillating. As the mop head 3 moves upward away from the cleaning area 1b, the mop head 3 drives the wringing component 5 to rotate in the opposite direction to the mop head 3, thereby draining the water in the water storage tank 52 into the wastewater area 1c. The middle of the front and rear sides of the wringing component 5 is pivotally mounted on or above the second inner tub 13. The edge of one side of the wringing component 5 is formed to scrape the wiping material 4. The scraping edge and the baffle are located on the left and right sides of the pivot, respectively.

[0104] It also includes a first limiting structure that limits the swing angle of the wringing component 5. As the mop head 3 moves downward into the cleaning zone 1b, the wringing component 5 flips forward to a first position and is blocked by the first limiting structure. The first limiting structure provides support for the wringing component 5.

[0105] The second inner tub 13 is provided with a bristle strip 8, and the mounting frame 9 is provided with a relief groove 93 for the bristle strip 8 to enter. The two ends of the bristle strip 8 abut against the side wall of the relief groove 93 to limit the mounting frame 9.

[0106] A water baffle 1b4 is provided in the cleaning area 1b, and the water baffle 1b4 is positioned away from the back plate of the mop head 3 that enters the cleaning area 1b.

[0107] The working principle and process of this cleaning tool embodiment are as follows:

[0108] like Figures 1-5 As shown, 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 1d. When the water in the cleaning zone 1b exceeds the outlet 1d2 of the water supply channel 1d, 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.

[0109] like Figures 6-10 As shown, after water supply is complete, switch 6 is turned off, and mop head 3 enters cleaning zone 1b. The water level in cleaning zone 1b when it exceeds the outlet 1d2 of water supply channel 1d is the initial water level S1. 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 material 4 is higher than the second water level S2. Moving mop head 3 up and down, the wringing component 5 squeezes and cleans the wiping material 4. Each time, the wastewater squeezed off the wiping material 4 is transferred to wastewater zone 1c through the first water transfer channel D1. As mop head 3 moves downward into cleaning zone 1b, the water in the second water transfer channel D2 flows back to the wiping material 4, allowing it to be absorbed by the wiping material 4 with less water content. This process is repeated multiple times until the water in cleaning zone 1b is completely transferred. After moving mop head 3 up and down a few more times, the wringing component 5 can fully squeeze the water off the wiping material 4. For the second cleaning, simply turn on switch 6 again and repeat the above steps.

[0110] 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.

[0111] 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.

[0112] like Figure 18 The following is a second embodiment of the present invention.

[0113] 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 squeezing component 5 contacts the wiping material 4, and the squeezed 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 1b6 to the wastewater zone 1c.

[0114] 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. They are merely for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model. 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 connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
