Description

Technical Field

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

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

[0003] For example, Chinese utility model patent CN201821203889.3 (publication number CN209863678U) discloses a flat mop tool, including a mop bucket and a flat mop. The mop bucket has a separate wringing area and a separate water-holding area, and the wringing area is equipped with a squeezing device. The flat mop includes a cleaning material, a mop handle, and a flat mop plate connected to the lower end of the mop handle. In use, the flat mop is rotated to a squeezing state, and then the squeezing device is inserted into the wringing area. The mop moves up and down to squeeze the cleaning material, and the squeezed water is transferred to the water-holding area through a water transfer device. Since the amount of water squeezed out when the cleaning material is squeezed is greater than the amount of water entering the wringing area from the water-holding area through the slow-release mechanism, after multiple repetitions, almost all the water in the wringing area can be transferred to the water-holding area, and the cleaning material is also squeezed dry in the process. Afterwards, the water in the water-holding area enters the wringing area through the slow-release mechanism. When the flat mop gets dirty, it can then enter the wringing area for wringing and cleaning.

[0004] This type of flat mop has the following drawbacks: It requires a full water supply for each cleaning cycle, necessitating refilling from the tap afterward. It lacks automatic water supply to the washing area, and the washing and wringing processes are separated into two distinct zones, requiring two separate operations to complete each cleaning session, making it inconvenient. Furthermore, the wastewater washed off the surfaces is drained back into the water collection area, contaminating the water cup. This contaminated water then flows through the slow-release mechanism into the wringing area, meaning the water used for the next mop wash is not clean, affecting the overall cleanliness of the surfaces.

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

[0006] The technical problem to be solved by this utility model is to provide a cleaning device with a flat mop that can fully wet and clean the wiping object and complete the cleaning and wringing operations in the same area, in light of the above-mentioned existing technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaner with a flat mop, comprising a cleaning bucket and a mop, wherein the mop includes a mop head rotatably connected to the lower end of the mop handle, and the mop head is provided with a wiping agent; characterized in that: the cleaning bucket includes an outer bucket, a clean water bucket, and a washing bucket, wherein the clean water bucket and the washing bucket are at least partially installed inside the outer bucket, the bottom of the washing bucket is provided with a support member that supports the bottom end of the mop head entering therein, and the middle parts of the clean water bucket and the washing bucket are connected by a water supply channel, wherein the water inlet end of the water supply channel is located at... The water supply channel is controlled by a switch at the bottom of the clean water bucket or the lower part of the surrounding body. The cleaning bucket is equipped with a wringing plate that squeezes the wiping material. The wringing plate is located above the water supply channel. When the switch is turned on, the clean water bucket fills the cleaning bucket with water. After the water is filled, the switch is turned off. The mop head moves and squeezes the wiping material between the wringing plate in the same position to move the wiping material and squeeze out water. The wiping material needs to be moved up and down at least twice by the mop handle for most of the liquid from the clean water bucket to be transferred from the cleaning bucket to the outer bucket.

[0008] Preferably, the switch is elongated, with its upper end extending above the cleaning area for operation. The upper end of the switch has a groove or rib for operation. Lowering the switch closes the water supply channel, while raising it opens it. The exposed cleaning tub at the upper end facilitates user operation by lifting the switch. Since the flat mop head also moves up and down during cleaning, lowering the switch to close the water supply channel better coordinates with the mop head's movement.

[0009] In a further improvement, the switch is constrained to the inner wall of the squeezing zone by a ribbed guide structure. The guide groove in the ribbed guide structure is located on one of the inner wall of the squeezing zone and the side wall of the switch component, while the guide rib in the ribbed guide structure is located on the other of the inner wall of the squeezing zone and the side wall of the switch component. The ribbed guide structure allows the switch to run along a predetermined trajectory and applies a force to the switch component towards the outlet end of the water supply channel, enabling the switch component to better close the outlet end of the water supply channel and prevent leakage.

[0010] To further ensure that the switch component keeps the outlet end of the water supply channel closed, as an improvement, the aforementioned squeezing area is provided with an upwardly protruding boss that guides the lower end of the switch component. The boss applies a force to the lower end of the switch component in a direction close to the outlet end of the water supply channel.

[0011] To simplify the operation process and eliminate the need for additional action when closing the switch, it is preferable that the switch has a protruding linkage part that can be triggered by a mop head inserted into the cleaning tub to move downward.

[0012] Further improvements include the formation of a drainage channel above the wringer to drain some of the water squeezed from the wiped item into the outer bucket and a return channel to return the water to the washing bucket. During washing, the flat mop head moves up and down inside the washing bucket, using the wringer to scrape and clean the wiped item. Each time, some wastewater squeezed from the wiped item flows into the outer bucket through the drainage channel, while some wastewater flows back to the washing bucket through the return channel, replenishing the wiping item in the washing bucket. This means that initially, the water in the washing bucket does not need to completely wet the wiped item, saving water or allowing for multiple applications of water to wet the item.

[0013] To ensure optimal water return timing, the water return channel can switch between a recirculation state and a non-recirculation state as the mop head moves up and down. When the mop head is lowered, it is in a wringing state, and the recirculation precisely replenishes the moisture on the wiped items. When the mop head is raised, the recirculation stops, avoiding the need to replenish moisture on wiped items that do not require it.

[0014] To achieve a reasonable and simple structure for forming the return water channel, preferably, the aforementioned wringer has a scraping edge for scraping water from the wiping material. The end of the wringer away from the scraping edge has an upward-extending baffle wall. The baffle wall and the wringer together form the return water channel, with the upper end open and the end facing the wiping material inserted into the washing tub also open. Only the baffle wall is needed to form both the drainage and return channels on the wringer, eliminating the need for additional components. This simple structure facilitates manufacturing and assembly.

[0015] To form a drainage channel using a reasonable and simple structure, the area above the aforementioned water-retaining wall forms the drainage channel.

[0016] As an improvement, the aforementioned wringer is provided with pivots on both the front and rear sides. The wringer is pivotally connected to the washing tub and can swing. This structure allows the squeezing edge of the wringer to swing up and down. When the squeezing edge swings downward to a near-horizontal position, it gets closer to the object being wiped, resulting in greater pressure and easier wringing. When the squeezing edge swings upward, it moves further away from the object, making it easier for the flat mop head to disengage from the squeezing port. The squeezing edge and the water-blocking wall are located on the left and right sides of the pivot. When the mop head enters the washing tub downward, the wringer swings until the squeezing edge is below the pivot, and the return water channel is in a return water state. When the mop head leaves the washing tub upward, the wringer swings until the squeezing edge is above the pivot, and the return water channel is in a state that prevents return water.

[0017] To fully transfer water from the cleaning tub to the wastewater area, the top surface of the wringer has a further recessed transition water storage cavity. The upward-swinging wringer pours water from the transition water storage cavity into the outer tub. After several washes, when the amount of water on the wiped items is small and the energy of the squeezed water is insufficient to directly drain into the outer tub, the small amount of squeezed water is stored in the transition water storage cavity. This water can be drained into the outer tub by swinging, or it can be drained into the outer tub through a drain hole at the bottom of the transition water storage cavity. The system also includes a limiting structure to restrict the swing angle range of the wringer. As the mop head descends into the cleaning tub, the wringer is prevented from tilting downwards by the limiting structure.

[0018] Further improvements include the inclusion of support ribs and a buffer pad. The buffer block is fixed to the bottom surface of the cleaning tub, and the buffer pad extends beyond the outer bottom surface of the cleaning tub and contacts the inner bottom surface of the outer tub. The support ribs are located on the inner bottom surface of the cleaning tub, and their height is higher than that of the buffer pad. During the cleaning process, the mop head first contacts the support ribs. After being subjected to force, the cleaning tub undergoes a slight downward movement, at which point the mop head contacts the buffer pad. Since the buffer pad is made of rubber, direct impact from the mop head would damage it. The cleaning tub then transmits the force to the buffer pad, which then contacts the outer tub, thus preventing direct, hard impact from the mop head on both the cleaning tub and the outer tub, protecting them.

[0019] To achieve automatic, metered water supply, the top of the aforementioned clean water tank is sealed, and the water supply channel also serves as an air intake channel. This allows air to enter the enclosed space above the liquid surface in the cleaning tank through the water supply channel while water is being poured into the cleaning tank, until the water in the cleaning tank submerges the outlet of the water supply channel. Because the top of the clean water tank is sealed, a vacuum is created above the liquid surface inside the tank. Once the water in the cleaning tank has submerged the outlet of the water supply channel, atmospheric pressure causes the clean water tank to automatically stop supplying water to the cleaning tank. Therefore, the amount of water supplied each time is constant, and the height distance between the outlet of the water supply channel and the bottom of the cleaning tank represents the actual amount of water used for cleaning.

[0020] To facilitate smooth air intake while supplying water, the water supply channel is set horizontally, or the water supply channel is set 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.

[0021] To achieve a seamless connection between the clean water tank and the washing tank, as an improvement, the clean water tank has a first insertion part on its side wall or bottom, with a first through hole connecting the outside to its inner cavity. The washing tank has a second insertion part on its side wall, with a second through hole connecting the outside to 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.

[0022] To increase the strength of the wringer opening and prevent deformation, the opening of the aforementioned cleaning bucket has an outward-flared reinforcing flange, and the top of the reinforcing flange has an upward-extending water-retaining rib. The water-retaining rib prevents water from flowing out excessively between the wringer plate and the wringer opening, thus avoiding the need for multiple mop head movements to remove all the water from the wringer.

[0023] Compared with existing technologies, the advantages of this invention are as follows: The clean water bucket is filled with clean water. During washing, the switch is turned on, and the clean water bucket supplies water to the washing bucket through the water supply channel. After the water is filled, the switch is turned off. The mop head moves and squeezes between the mop head and the wringer plate in the same position to move and squeeze the water from the object being wiped. The mop handle needs to move the object up and down at least twice to transfer most of the liquid from the clean water bucket to the outer bucket, ensuring that the object is fully soaked and repeatedly squeezed by the wringer plate for better cleaning. Repeatedly moving the mop up and down until the water in the washing bucket is mostly transferred out completely allows the water on the object to be thoroughly squeezed dry. Washing and squeezing are completed in just one washing bucket, making the squeezing operation more convenient. For a second wash, simply turn the switch on again, and the clean water bucket supplies water to the washing bucket through the water supply channel, repeating the above operation to complete the second wash, ensuring that the mop is always washed with clean water.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1-14 The figure shown is a preferred embodiment of the present invention.

[0040] A cleaner with a flat mop includes a cleaning bucket 1 and a mop. The mop includes a mop head 3 rotatably connected to the lower end of the mop handle 2. The mop head 3 is provided with a wiping material 4. The wiping material 4 can be a fiber cloth or foam.

[0041] The cleaning tub 1 includes an outer tub 11, a clean water tub 12, and a washing tub 13. The clean water tub 12 and the washing tub 13 are at least partially installed inside the outer tub 11. The opening of the washing tub 13 has an outwardly flared reinforcing flange 131, and the top of the reinforcing flange 131 has an upwardly extending water-blocking rib 132. The bottom of the washing tub 13 is provided with a support member 9 that supports the bottom end of the mop head 3 that enters therein. The support member 9 includes a support rib 91 and a buffer pad 92. The buffer pad 92 is fixed to the bottom surface of the washing tub 13, extends out of the outer bottom surface of the washing tub 13 and contacts the inner bottom surface of the outer tub 11. The support rib 91 is located on the inner bottom surface of the washing tub 13, and the height of the support rib 91 is higher than the height of the buffer pad 92.

[0042] The middle parts of the clean water bucket 12 and the washing bucket 13 are connected by a water supply channel D. The water inlet of the water supply channel D is located at the bottom of the clean water bucket 12 or at the lower part of its surrounding structure. The water supply channel D is controlled to open and close by a switch 6. The washing bucket 13 is provided with a wringing plate 5 that squeezes the wiping material 4. The wringing plate 5 is located above the water supply channel D. When the switch 6 is turned on, the clean water bucket 12 fills the washing bucket 13 with water. After the water is filled, the switch 6 is turned off. The mop head 3 moves and squeezes the wiping material 4 between the wringing plate 5 in the same position, thereby moving and squeezing the water out of the wiping material 4. The wiping material 4 needs to be moved up and down at least twice by the mop handle for the water in the washing bucket 13 to transfer most of the liquid from the clean water bucket 12 to the outer bucket 11.

[0043] The switch 6 is elongated, with its upper end extending above the cleaning area for operation. The upper end of the switch 6 has a groove or rib for operation. Moving the switch 6 downwards closes the water supply channel D, while moving it upwards opens the water supply channel D. The switch 6 has a protruding linkage part 61 that can be triggered downwards by a mop head 3 inserted into the cleaning tub 13.

[0044] The switch 6 is constrained to the inner wall of the cleaning tub 13 by a ribbed guide structure 10. The guide groove 101 in the ribbed guide structure 10 is located on one of the inner wall of the squeezing area 1a and the side wall of the switch 6, and the guide rib 102 in the ribbed guide structure 10 is located on the other of the inner wall of the squeezing area 1a and the side wall of the switch 6. The cleaning tub 13 has an upwardly protruding boss 103 that guides the lower end of the switch 6. The boss 103 applies a force to the lower end of the switch 6 in a direction close to the outlet end D2 of the water supply channel D.

[0045] Above the wringer 5, a drainage channel S1 is formed to drain a portion of the water squeezed off the wiping material 4 into the outer bucket 11, and a water return channel S2 is formed to return a portion of the water to the washing bucket 13. The water return channel S2 can switch between the state of water return and non-return as the mop head 3 moves up and down.

[0046] The wringer 5 has a scraping edge 51 for scraping water from the wiping material 4. At one end of the wringer 5 away from the scraping edge, there is an upwardly extending baffle wall 52. The baffle wall 52 and the wringer 5 together form the return water channel S2. The upper end of the return water channel S2 is open, and the end of the return water channel S2 facing the wiping material 4 inserted into the washing tub 13 is also open. The area above the baffle wall 52 forms the drainage channel S1.

[0047] The wringer 5 has pivots 53 on both the front and rear sides. The wringer 5 is pivotally connected to the washing tub 13 via the pivots 53 and can swing. The scraping edge 51 and the water-blocking wall 52 are located on the left and right sides of the pivots 53. When the mop head 3 enters the washing tub 13 downwards, the wringer 5 swings until the scraping edge 51 is below the pivots 53, and the return water channel S2 is in the return water state. When the mop head 3 leaves the washing tub 13 upwards, the wringer 5 swings until the scraping edge 51 is above the pivots 53, and the return water channel S2 is in the anti-return water state.

[0048] The top surface of the wringer 5 has a further recessed transition water storage cavity 54. The upward swinging wringer 5 can pour the water in the transition water storage cavity 54 into the outer bucket 11. It also includes a limiting structure 7 that limits the swing angle range of the wringer 5. When the mop head 3 enters the washing bucket 13 downward, the wringer 5 is blocked by the limiting structure 7 and cannot be flipped downward.

[0049] The top of the clean water tank 12 is closed. The water supply channel D also serves as an air inlet channel, allowing air to enter the enclosed space above the liquid surface in the cleaning tank 13 through the water supply channel D while water is being poured into the cleaning tank 13, until the water in the cleaning tank 13 submerges the outlet D2 of the water supply channel D. The water supply channel D is horizontally positioned, or it is inclined downwards from the inlet D1 towards the outlet D2, or at least the top of the inlet D1 of the water supply channel D is higher than the top of the outlet D2.

[0050] The clean water tank 12 has a first insertion part 8a on its side wall or bottom, and the first insertion part 8a has a first through hole 8a1 that connects to the outside and its inner cavity. The cleaning tank 13 has a second insertion part 8b on its side wall, and the second insertion part 8b has a second through hole 8b1 that connects to the outside and its inner cavity. The second insertion part 8b is inserted into the first through hole 8a1, and the second through hole 8b1 constitutes the water supply channel D. Alternatively, the first insertion part 8a is inserted into the second through hole 8b1, and the first through hole 8a1 constitutes the water supply channel D.

[0051] The clean water bucket 12 is filled with clean water. During cleaning, the switch 6 is turned on, and the clean water bucket 12 supplies water to the cleaning bucket 13 through the water supply channel D. After the water is filled, the switch 6 is turned off. The mop head 3 moves and squeezes between the mop head and the wringer 5 in the same position to move and squeeze the water off the wiping surface 4. The mop head 2 needs to move the wiping surface 4 up and down at least twice to transfer most of the cleaning water from the clean water bucket 12 to the outer bucket 11. This ensures that the wiping surface 4 is fully soaked and squeezed by the wringer 5 multiple times for better cleaning. The mop is moved up and down repeatedly until the water in the cleaning bucket 13 is basically transferred out, and the water on the wiping surface 4 is fully squeezed dry. Cleaning and squeezing are completed in only one cleaning bucket 13, making the squeezing operation more convenient. For the second cleaning, simply turn on the switch again, and the clean water bucket 12 supplies water to the cleaning bucket 13 through the water supply channel D again, and repeat the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.
