Description

Technical Field

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

[0002] There are numerous patents related to mop buckets used for cleaning flat mops. A representative patent is Chinese utility model patent CN201821203889.3 (publication number CN209863678U), which discloses a flat mop tool including a mop bucket and a flat mop. The mop bucket has a separate wringing area and a separate water-holding area, and the wringing area is equipped with a squeezing device. The flat mop includes a cleaning material, a mop handle, and a flat mop plate connected to the lower end of the mop handle. In use, the flat mop is rotated to a squeezing state, and then the squeezing device is inserted into the wringing area. Moving it up and down squeezes the cleaning material, and the squeezed water is transferred to the water-holding area via a water transfer device. Because the amount of water squeezed out is greater than the amount of water entering the wringing area from the water-holding area through the slow-release mechanism, after multiple repetitions, almost all the water in the wringing area can be transferred to the water-holding area, and the cleaning material is also squeezed dry during this process. Afterwards, the water in the water-holding area enters the wringing area through the slow-release mechanism. When the flat mop gets dirty, it can then enter the wringing area for wringing and cleaning.

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

[0004] The flat mop cleaning tool has the following drawbacks: Washing and wringing are separated into two areas, requiring two separate operations to complete one cleaning task, making the cleaning process inconvenient. Furthermore, the wastewater washed off the mop each time 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 cleanliness of the mop. The slow-release mechanism may have small holes that cannot be closed, meaning that during the cleaning and wringing process, the lower part of the mop may remain soaked in water from the wringing area, resulting in poor wringing and incomplete drying.

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

[0006] The technical problem to be solved by this utility model is to provide a cleaning device that ensures clean water for each cleaning operation, can complete cleaning and wringing in one area at the same time, and allows for smooth cleaning and wringing operations, in light of the above-mentioned existing technology. This cleaning device also reduces the amount of water used for each cleaning operation, thus saving water.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning device for 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; the mop head and the mop handle can be positioned by a positioning device to keep the mop head in a cleaning and wringing state; when mopping, the mop head is disengaged from the control of the positioning device and rotates to the mopping state; characterized in that: the cleaning bucket has a clean water area, a cleaning area and a wastewater area that are independent of each other; the clean water area and the cleaning area are connected by a water supply channel in the middle, and the cleaning area is provided with a device that squeezes the wiping agent. The water-squeezing component is located below the water-squeezing component. It also includes a switch for opening and closing the water-squeezing channel. The switch has a protruding linkage that can be triggered by a mop head inserted into the cleaning area to move downwards. The mop head rotates to a squeezing state that is basically parallel to the mop handle. In this state, the mop head and mop handle are inserted into the cleaning area and move up and down. The inner wall of the cleaning area supports the back plate of the mop head. The water-squeezing component squeezes and scrapes the wiping material. The cleaning area also has a drainage channel for draining the water squeezed from the wiping material to the wastewater area and a return channel for returning to the cleaning area.

[0008] Preferably, the aforementioned wringing component is plate-shaped and oscillating. The front of the wringing component forms a scraper section whose thickness decreases from back to front. At least behind the top surface of the wringing component, an upwardly extending baffle is provided. The drainage channel is formed above the baffle, and the front of the baffle and the top surface of the wringing component together form the return channel. The scraper section, whose thickness decreases from back to front, is more effective at removing dirt from the wiped object. The baffle obstructs the water flow, causing it to flow back to the cleaning area. The limited height of the baffle allows some of the water squeezed off the wiped object to pass over the baffle, thus forming the drainage channel.

[0009] To facilitate quick installation of the squeezing component into the cleaning area and its ability to swing, the squeezing component is provided with pivots on both the left and right sides. The squeezing component is pivotally connected to the cleaning tank via the pivots and can swing. The scraper and baffle are located on the front and rear sides of the pivots.

[0010] To ensure the wringing component swings within a suitable angle range, a limiting structure is included to restrict the swing angle range of the wringing component. When the mop head enters the cleaning chamber downwards, the wringing component is prevented from flipping downwards by the limiting structure; similarly, when the mop head leaves the cleaning chamber upwards, the wringing component is prevented from flipping upwards by the limiting structure. A downward-swinging wringing component allows the scraper to get closer to the object being wiped, resulting in better wiping performance. Conversely, an upward-flipping wringing component keeps the scraper further away from the object, facilitating mop head detachment.

[0011] Alternatively, 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 zone, the inner cavity of the first inner tank constitutes the clean water zone, and the inner cavity of the second inner tank constitutes the washing zone. The first and second inner tanks are at least partially installed inside the outer tank. This design better isolates the outer tank from the two inner tanks, preventing wastewater from the outer tank from entering the two inner tanks. Alternatively, a partition can be installed inside the outer tank to divide it into a clean water zone, a washing zone, and a wastewater zone.

[0012] To ensure that even with a small amount of water, the maximum water level in the washing area rises as high as possible after the mop enters, at least part of the inner wall of the second inner tub is inclined, creating an flared shape in the washing area from bottom to top. This allows for the immersion of as many items as possible in the washing area with relatively little water.

[0013] Preferably, the switch is elongated, with its upper end extending above the cleaning area for operation. Lowering the switch closes the water supply channel, while raising it opens it. The switch automatically closes when the mop moves down, eliminating the need for manual operation and allowing for better coordination with the mop – a more rational design.

[0014] In a further improvement, the switch is constrained to the inner wall of the cleaning zone by a ribbed guide structure. The guide groove in the ribbed guide structure is located on one of the inner wall of the cleaning zone and the side wall of the switch, while the guide rib in the ribbed guide structure is located on the other. 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.

[0015] To ensure that the switch does not move further after it has been lowered into position, the inner wall of the cleaning area is provided with a stop that blocks the switch when it is lowered to close the water supply channel.

[0016] Compared with the prior art, the advantages of this utility model are as follows: The cleaning bucket has independent clean water zone, washing zone, and wastewater zone. The clean water zone is filled with clean water. During washing, when the switch is turned on, the clean water zone supplies water to the washing zone through the water supply channel. The mop head rotates to a squeezing state that is basically parallel to the mop handle. The mop head and mop handle can be positioned by a positioning device to keep the mop head in the washing and squeezing state, ensuring that the mop head does not shake during the cleaning process and remains in a vertical position. In this state, the mop head and mop handle are inserted into the washing zone. The mop head triggers the linkage on the switch, the switch closes the water supply channel, and the mop head moves up and down in the washing zone. Because the inner wall of the washing zone supports the back plate of the mop head, the squeezing component has a greater contact force with the wiping object. The water component scrapes and cleans the items being wiped. Most of the wastewater scraped off the items is drained into the wastewater area through the drain channel, while a small portion flows back into the cleaning area through the return channel to soak the items there. This means that initially, the water in the cleaning area does not need to completely soak the items, thus saving water. By repeatedly moving the mop up and down until the water in the cleaning area is mostly transferred away through the drain channel, the items can be thoroughly dried. Cleaning and drying are completed in just one cleaning area, making the wringing operation more convenient. For the second cleaning, simply turn on the switch again, and the clean water area will supply water to the cleaning area through the water supply channel, repeating the above operation to complete the second cleaning, ensuring that the mop is cleaned with clean water each time.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-16 The figure shown is a preferred embodiment of the present invention.

[0035] A cleaning appliance for 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 a mop handle 2. The mop head 3 is provided with a wiping material 4, which can be a microfiber cloth or foam. The mop head 3 is kept in a cleaning and wringing state by a positioning device; when mopping, the mop head 3 is disengaged from the control of the positioning device and rotates to the mopping state.

[0036] The cleaning tank 1 has three independent areas: a clean water zone 1a, a washing zone 1b, and a wastewater zone 1c. The clean water zone 1a and the washing zone 1b are connected by a water supply channel D. The washing zone 1b is equipped with a squeezing component 5 that squeezes the wiping material 4. The outlet end of the water supply channel D is located below the squeezing component 5. The squeezing component 5 is plate-shaped and can swing. The front part of the squeezing component 5 forms a scraper part 51 whose thickness decreases from back to front. At least behind the top surface of the squeezing component 5, there is an upwardly extending baffle 52. The drainage channel S1 is formed above the baffle 52. The front of the baffle 52 and the top surface of the squeezing component 5 form the return channel S2. Pivots 53 are provided on the left and right sides of the squeezing component 5. The squeezing component 5 is pivotally connected to the cleaning tank through the pivots 53 and can swing. The scraper part 51 and the baffle 52 are located on the front and rear sides of the pivots 53. It also includes a limiting structure 7 that limits the swing angle range of the wringing component 5. When the mop head 3 enters the cleaning chamber downwards, the wringing component 5 is blocked by the limiting structure 7 and cannot be flipped downwards. When the mop head 3 leaves the cleaning chamber upwards, the wringing component 5 is blocked by the limiting structure 7 and cannot be flipped upwards.

[0037] It also includes a switch 6 for opening and closing the water supply channel D. The switch 6 has a protruding linkage part 61 that can be triggered to move downward by a mop head 3 inserted into the cleaning area 1b. The switch 6 is elongated, with its upper end extending above the cleaning area 1b for operation. Moving the switch 6 downward closes the water supply channel D, and moving the switch 6 upward opens the water supply channel D. The switch 6 is constrained to the inner wall of the cleaning area 1b by a ribbed guide structure 8. The guide groove 8a in the ribbed guide structure 8 is provided on one of the inner wall of the cleaning area 1b and the side wall of the switch 6, and the guide rib 8b in the ribbed guide structure 8 is provided on the other of the inner wall of the cleaning area 1b and the side wall of the switch 6. During the downward movement of the switch 6, the ribbed guide structure 8 applies a force to the switch 6 in the direction of approaching the water outlet D2 of the water supply channel D. The inner wall of the cleaning area 1b has a stop part 1b1 that blocks the downward movement of the switch 6 to close the water supply channel D.

[0038] The mop head 3 is rotated to a squeezeable state that is basically parallel to the mop handle 2. In this state, the mop head 3 and the mop handle 2 are inserted into the cleaning zone 1b and move up and down. The inner wall of the cleaning zone 1b supports the back plate of the mop head 3. The water squeezing component 5 is used to squeeze and scrape the wiping material 4. The cleaning zone 1b is also provided with a drainage channel S1 for draining the water squeezed off the wiping material 4 to the sewage zone 1c and a return channel S2 for returning to the cleaning zone 1b.

[0039] 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 the wastewater zone 1c, the inner cavity of the first inner tub 12 forms the clean water zone 1a, and the inner cavity of the second inner tub 13 forms 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. One inner wall of the second inner tub 13 is at least partially inclined, so that the cleaning zone 1b forms a flared shape from bottom to top.

[0040] The cleaning bucket 1 has three independent zones: a clean water zone 1a, a washing zone 1b, and a wastewater zone 1c. Clean water is added to the clean water zone 1a. During washing, switch 6 is turned on, and water from the clean water zone 1a to the washing zone 1b is supplied via the water supply channel D. The mop head 3 rotates to a squeezing state that is essentially parallel to the mop handle 2. A positioning device keeps the mop head 3 in a washing and squeezing state, ensuring it remains vertical and doesn't wobble during cleaning. In this state, the mop head 3 and mop handle 2 are inserted into the washing zone 1b. The mop head 3 triggers the linkage 61 on switch 6, closing the water supply channel D. The mop head 3 moves up and down within the washing zone 1b. Because the inner wall of the washing zone 1b supports the back plate 31 of the mop head 3, the squeezing component 5 has greater contact force with the wiping material 4. 5. The mop is scraped and cleaned by squeezing. Most of the wastewater squeezed from the mop 4 is discharged to the wastewater area 1c through the drain channel S1, and a small part of the wastewater flows back to the cleaning area 1b through the return channel S2 to soak the mop 4. This means that in the initial state, the water in the cleaning area 1b does not need to fully soak the mop 4, which saves water. The mop is moved up and down repeatedly until the water in the cleaning area 1b is basically transferred by the drain channel S1, which can fully squeeze the water out of the mop 4. The cleaning and squeezing are completed in only one cleaning area 1b, making the water squeezing operation more convenient. For the second cleaning, simply turn on the switch 6 again, and the clean water area supplies water to the cleaning area 1b again through the water supply channel D, and repeat the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.
