Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cleaning tools, especially a device suitable for cleaning flat mop or foamed cotton flat mop. BACKGROUND

[0002] The mop cleaning barrel for cleaning flat mop or foamed cotton flat mop mostly needs to fill water in the barrel body, and then the mop is put in for cleaning. Only the first time is clean water, and the next time is the second clean water after cleaning. After cleaning, the wringing operation is carried out in another area. There are many patents of mop barrels for cleaning flat mop, and the core is that the mop barrel has independent wringing area and independent water holding area. The water holding area is used for cleaning the mop, and the wringing area is used for wringing the mop. The water squeezed out by the wiping object is transferred to the water holding area through the water transfer device.

[0003] For example, the Chinese utility model patent with patent number CN201821203889.3 (publication number CN209863678U) discloses a flat mop tool, which comprises a mop barrel and a flat mop. The mop barrel has independent wringing area and independent water holding area. The barrel body of the wringing area is provided with a squeezing device. The flat mop comprises a wiping object, a mop rod, and a flat mop plate connected to the lower end of the mop rod. During use, the flat mop is rotated to a state where it can be squeezed, and then the squeezing device is inserted into the wringing area. The wiping object is squeezed by the squeezing device through up and down movement. The water squeezed out by the wiping object is transferred to the water holding area through the water transfer device. Because the amount of water squeezed out by the wiping object is greater than the amount of water entering the squeezing area from the water holding area through the slow-release mechanism, the water in the wringing area can be basically completely transferred to the water holding area after multiple reciprocations. The wiping object is also wrung out during this process. Then the water in the water holding area enters the wringing area through the slow-release mechanism. After the flat mop is used for mopping and the wiping object is dirty, it can enter the wringing area for wringing and cleaning.

[0004] This flat mop cleaning tool has the following defects: each cleaning operation is full of water, and the water needs to be refilled from the faucet after the operation is completed. It cannot automatically supply water to the cleaning area. Cleaning and wringing are divided into two areas, and two operations in different areas are needed to complete one cleaning work. The cleaning operation is not convenient. In addition, the sewage washed off from the wiping object each time is discharged back to the water holding area, which pollutes the water cup in the water holding area. The polluted water in the water holding area enters the wringing area through the slow-release mechanism, so that the water used for cleaning the mop the next time is not clean water, which affects the cleaning of the wiping object.

[0005] In summary, the aforementioned flat mop cleaning tool can be further improved. UTILITY MODEL CONTENTS

[0006] The technical problem to be solved by this utility model is to provide a device for a cleaning flat mop that completes the washing and wringing operations in the same area, ensures that the water used for each washing and wringing is clean water, and can automatically provide a quantitative amount of clean water each time, 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 device for cleaning a flat mop, 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; the cleaning bucket has a clean water area, a washing area and a wastewater area that are independent of each other; characterized in that: the middle part of the clean water area and the washing area are connected by a water supply channel, the water supply channel is controlled to open and close by a switch, the top of the clean water area is closed, the water supply channel also serves as an air intake channel, so that while water is injected into the washing area by the water supply channel, air enters the clean water area through the water supply channel until the water in the washing area submerges the outlet of the water supply channel; the length of the automatic water storage area of ​​the washing area is L1, the width of the automatic water storage area of ​​the washing area is L2, and L1 is greater than L2; the bottom of the washing area is provided with a support component that supports the bottom end of the mop head entering therein, and the washing area is provided with a support component that supports the bottom end of the mop head entering therein. The wiping material forms a squeezing plate, which has a scraping edge for scraping water off the wiping material. At one end of the wiping plate away from the scraping edge, there is an upward-extending water-blocking wall. The lower end of the wiping material is fitted or fastened to the back plate of the mop head, and the bottom surface of the wiping material is adhered to the back plate of the mop head. The mop head rotates to a squeezing state that is substantially 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, scraping the wiping material through the squeezing plate. As the mop head moves downward into the cleaning area, the top surface of the squeezing plate forms a water-guiding surface that slopes downward from the water-blocking wall towards the scraping edge. The outlet of the water supply channel is located below the water-guiding surface. The water-blocking wall blocks some of the water scraped off the wiping material and allows it to flow back towards the cleaning bucket along the water-guiding surface. Some of the water scraped off the wiping material passes over the water-blocking wall and flows into the wastewater area.

[0008] To achieve a relatively simple structure for supporting the mop head, the aforementioned support components are support columns, support platforms, or support frames located within the cleaning area.

[0009] The aforementioned support components are positioned below the outlet end of the water supply channel.

[0010] To ensure that the wringer can better squeeze and scrape the object being wiped when the mop head moves downward, and at the same time, to reduce the friction between the wringer and the object being wiped when the mop head moves upward, the wringer can swing. The wringer also includes a limiting structure that limits the swing angle range of the wringer. When the mop head moves downward into the cleaning area, the wringer is blocked by the limiting structure and cannot be flipped downward.

[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 maintain the overall aesthetic appearance of the handle-handled cleaning bucket, the outer bucket is equipped with a pressure cap that forms a constraint on the upper ends of the first and second inner buckets. An opening can be made in the pressure cap to connect with the second inner bucket, and this opening can serve as part of the cleaning area. A wringer can be installed within the opening.

[0013] 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.

[0014] Preferably, the initial water level is reached when the water in the cleaning zone surpasses 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, thus reducing the amount of water used in each cleaning cycle.

[0015] To improve the water supply channel's ability to stably intake air while supplying water, and to ensure that water can be quickly discharged from the water supply channel, preferably, the water supply channel is set horizontally, or the water supply channel is set inclined downwards from the water inlet end to the water outlet end, or at least the top of the water inlet end of the water supply channel is higher than the top of the water outlet end.

[0016] Compared with existing technologies, 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. Because the top of the clean water zone is closed, when the switch is turned on during cleaning, the clean water zone supplies water to the washing zone through the water supply channel. At the same time, air enters the clean water zone above the liquid surface through the water supply channel. When the water in the washing zone exceeds the outlet of the water supply channel, the clean water zone automatically stops supplying water to the washing zone under atmospheric pressure. Therefore, the amount of water supplied each time is constant. Then the switch is turned off, and the mop head moves up and down in the washing zone, using the wringer to scrape and clean the object being wiped. The lower end of the object is fitted or fastened to the back plate of the mop head, and the bottom surface of the object is adhered to the back plate of the mop head. In this way, during the downward movement of the mop head, the lower end of the object, because it is fitted or fastened to the back plate of the mop head, will not warp under the scraping action of the wringer, ensuring smooth and unobstructed cleaning operation. The water-blocking wall prevents a small amount of water squeezed off the cleaning surface from the surface and directs it back towards the cleaning area, wetting the cleaning surface. This means that initially, the water in the cleaning area does not need to completely wet the cleaning surface, saving water. Most of the water squeezed off the cleaning surface flows over the water-blocking wall into the wastewater area. By repeatedly moving the mop up and down until the water in the cleaning area is basically removed, the water on the cleaning surface can be thoroughly squeezed out. Cleaning and squeezing are completed in only one cleaning area, making the squeezing 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 again through the water supply channel, repeating the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.

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

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

[0035] A device for cleaning 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, which can be a fiber cloth or foam.

[0036] The cleaning tank has three independent areas: a clean water zone 1a, a cleaning zone 1b, and a wastewater zone 1c. The clean water zone 1a and the cleaning zone 1b are connected by a water supply channel D, which is controlled by a switch 6. The top of the clean water zone 1a is closed. The water supply channel D also serves as an air intake channel, allowing air to enter the clean water zone 1a through the water supply channel D while water is being supplied to the cleaning zone 1b, until the water in the cleaning zone 1b submerges the outlet end D2 of the water supply channel D. The length of the automatic water storage area in the cleaning zone 1b is L1, and the width of the automatic water storage area in the cleaning zone 1b is L2, where L1 is greater than L2. The water supply channel D is horizontally positioned, or it is inclined downwards from the inlet end D1 towards the outlet end D2, or at least the top of the inlet end D1 of the water supply channel D is higher than the top of the outlet end D2.

[0037] The bottom of the cleaning zone 1b is provided with a support component 7 that supports the bottom end of the mop head 3 that enters therein. The position of the support component 7 is lower than the position of the water outlet D2 of the water supply channel D. The support component 7 is a support column, support platform or support frame provided in the cleaning zone 1b.

[0038] The cleaning area 1b is provided with a wringer 6 that squeezes the wiping material 4. The wringer 6 has a scraping edge 53 for scraping water from the wiping material 4. The wringer 6 has an upwardly extending water-blocking wall 51 at the end away from the scraping edge 53. The wringer 6 can swing and also includes a limiting structure 8 that limits the swing angle range of the wringer 6. When the mop head 3 enters the cleaning area 1b downward, the wringer 6 is blocked by the limiting structure 8 and cannot be flipped downward.

[0039] The lower end of the wiping material 4 is fitted or fastened to the 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 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 wiping material 4 is squeezed and scraped by the wringer 5. As the mop head 3 moves downward into the cleaning zone 1b, the top surface of the wringer 6 forms a water guide surface 63 that is inclined downward from the water-blocking wall 51 towards the scraping edge 53. The outlet of the water supply channel D is located below the water guide surface 63. The water-blocking wall 51 blocks some of the water scraped off the wiping material 4 and flows back along the water guide surface 63 towards the cleaning bucket. Some of the water scraped off the wiping material 4 passes over the water-blocking wall 51 and flows into the sewage zone 1c.

[0040] The water level in the cleaning zone 1b is the initial water level h1 when it exceeds the outlet of the water supply channel D. 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 h2, and the height of the wiping material 4 is higher than the second water level h2.

[0041] 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. The outer tub 11 is provided with a pressure cap that forms a constraint on the upper ends of the first inner tub 12 and the second inner tub 13. At least partially, one inner wall of the second inner tub 13 is inclined, so that the cleaning zone 1b forms a flared shape from bottom to top.

[0042] The cleaning tank 1 has three independent clean water zones: 1a, 1b, and 1c. Clean water is added to the clean water zone 1a. Because the top of the clean water zone 1a is closed, when the switch 6 is turned on during cleaning, the clean water zone 1a supplies water to the 1b through the water supply channel D. At the same time, air enters the clean water zone 1a above the liquid surface through the water supply channel D. When the water in the 1b has submerged the outlet D2 of the water supply channel D, the clean water zone 1a automatically stops supplying water to the 1b under atmospheric pressure. Therefore, the amount of water supplied each time is constant. Then, switch 6 is turned off, and mop head 3 moves up and down in cleaning area 1b. The wiping plate 6 is used to squeeze and clean the wiping material 4. The lower end of the wiping material 4 is fitted or fastened to the back plate 31 of mop head 3, and the bottom surface of the wiping material 4 is adhered to the back plate 31 of mop head 3. In this way, during the downward movement of mop head 3, the lower end of the wiping material 4 will not be warped under the squeezing edge 53 of the squeezing plate 6 because it is fitted or fastened to the back plate 31 of mop head 3, thus ensuring that the cleaning operation is smooth and without jamming. The water-blocking wall 51 blocks a small portion of the water squeezed off the wiping material 4 and directs it back along the water guide surface 63 towards the cleaning area 1b, wetting the wiping material 4 within it. This means that in the initial state, the water in the cleaning area 1b does not need to fully wet the wiping material 4, thus saving water. Most of the water squeezed off the wiping material 4 flows over the water-blocking wall 51 and into the wastewater area 1c. By repeatedly moving the mop up and down until the water in the cleaning area 1b is basically removed, the water on the wiping material 4 can be fully squeezed out. 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 1a supplies water to the cleaning area again through the water supply channel D, repeating the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned.
