Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a self-cleaning mopping mechanism. Background Art

[0002] Currently, the most common household mopping systems on the market use fully automated mopping technology. These solutions all involve attaching a mopping cloth to the bottom of a mobile, self-navigating platform. Water then slowly seeps through a sump above the mopping cloth to replenish the mopping process. This solution keeps the mopping cloth moist during movement, thereby absorbing fine dust from the floor.

[0003] When facing the outdoor surface that needs to be cleaned over a large area, the existing household mopping structure has problems such as the mopping cloth needing to be replaced frequently. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to:

[0005] 1. Provide a mopping structure with a self-cleaning function, so that it can clean the mopping cloth during work and extend the effective working time of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A self-cleaning mopping mechanism comprises a frame, a drive roller assembly, a squeezing roller, a drive device, a cleaning device, a mop belt, and an adjustment device. The drive roller assembly is mounted on the frame, the mop belt is sleeved on the drive roller assembly and driven by the drive roller assembly to generate relative friction with the ground surface, the drive device is connected to the drive roller assembly, and the mop belt passes between the squeezing roller and the drive roller assembly.

[0008] The cleaning device includes a water collection tank, the cleaning device is arranged in the water collection tank, the third roller is located in the water collection tank, the adjustment device is arranged on the frame, and the movable end of the adjustment device is connected to the third roller

[0009] This solution uses a water collection tank to soak the mop belt with water-absorbed dirt, so that the dirt enters the sewage in the water collection tank, thereby achieving a self-cleaning function for the mop belt.

[0010] Preferably, the driving roller group includes a first roller, a second roller, a third roller, a fourth roller and a fifth roller, and the first roller, the second roller, the third roller, the fourth roller, the fifth roller and the water-squeezing roller are arranged parallel to each other, and the first roller, the second roller, the third roller, the fourth roller, the fifth roller and the water-squeezing roller are all rotatably connected to the frame, and the mop belt is sequentially mounted on the first roller, the second roller, the third roller, the fourth roller and the fifth roller, and the mop belt passes between the water-squeezing roller and the fifth roller.

[0011] Optionally, the driving device includes a synchronous belt and a driving motor, the output end of the driving motor is connected to the synchronous belt, and the synchronous belt is connected to the fifth roller.

[0012] Optionally, the cleaning device also includes a spraying device and a filtering device, the water collection tank is arranged in the middle of the frame, the position of the filtering device corresponds to the position of the fifth roller, the spraying device has at least two spraying systems, at least one spraying system of the spraying device is connected to the filtering device, and at least one spraying system of the spraying device is connected to the clean water tank.

[0013] This solution uses a spray device combined with a filter device to perform a secondary rinse on the mop belt. Specifically, technicians can use existing components such as water pumps, pipes, and nozzles in the existing technology to assemble a spray system that meets the requirements of this solution.

[0014] Optionally, a sewage outlet is also provided at the bottom of the water collecting tank.

[0015] The drain outlet is mainly used to discharge sludge and debris from the bottom of the sump. When using it, ensure that there is enough sewage in the sump to flush the sludge into the drain outlet. You can also open this structure during sewage discharge to manually return the sludge to the drain outlet and remove the debris.

[0016] Optionally, the first roller, the second roller, the third roller, the fourth roller, and the fifth roller are all provided with V-shaped grooves.

[0017] The V-groove design is mainly used to reduce the slippage between the mopping belt and the roller, and at the same time reduce the deviation of the mopping belt.

[0018] Optionally, the tip direction of the V-groove on the fifth roller is opposite to the rotation direction of the fifth roller.

[0019] In addition to the above-mentioned effect of reducing slippage, the V-groove on the fifth roller also cooperates with the water squeezing roller to produce the effect of converging water flow during squeezing.

[0020] Optionally, the adjusting device is further provided with a comb fence, and the position of the comb fence corresponds to the position of the mop belt.

[0021] The comb fence in this solution can scrape off the filaments and dirt on the mop belt when the comb fence produces relative friction with the mop belt.

[0022] The beneficial technical effects of the utility model are as follows: the mop belt with water-absorbed dirt is immersed in the water collection tank, so that the dirt enters the sewage in the water collection tank, thereby realizing the self-cleaning function of the mop belt; the mop belt is rinsed twice by the spray device combined with the filtering device.

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0030] Example 1

[0031] Reference Figure 1-4As shown, a self-cleaning mopping mechanism includes a frame 1, a first roller 2, a second roller 3, a third roller 4, a fourth roller 5, a fifth roller 6, a water squeezing roller 7, a driving device, a cleaning device, a mop belt 8 and an adjusting device 9.

[0032] The first roller 2, the second roller 3, the third roller 4, the fourth roller 5, the fifth roller 6, and the squeeze roller 7 are arranged parallel to each other and are all rotatably connected to the frame 1. The mop belt 8 is sequentially sleeved on the first roller 2, the second roller 3, the third roller 4, the fourth roller 5, the fifth roller 6, and the squeeze roller 7. The mop belt 8 passes between the squeeze roller 7 and the fifth roller 6. The moisture content in the mop belt 8 can be controlled by adjusting the spacing between the squeeze roller 7 and the fifth roller 6. The specific adjustment method can refer to the existing spacing adjustment device.

[0033] The first roller 2 , the second roller 3 , the third roller 4 , the fourth roller 5 and the fifth roller 6 are all provided with V-shaped grooves, which are mainly used to increase the maximum static friction between them and the mop belt 8 and reduce the slippage between them and the mop belt 8 .

[0034] The driving device includes a synchronous belt 11 and a driving motor 10 . The output end of the driving motor 10 is connected to the synchronous belt 11 . The synchronous belt 11 is connected to the fifth roller 6 and transmits the power of the driving motor 10 to the fifth roller 6 .

[0035] The cleaning device includes a sump 12, a spray device 13, and a filter device 14. The sump 12 is located in the middle of the frame 1. The aforementioned fourth roller 5 extends into the sump 12 via a crank, submerging the mop belt 8 passing through the fourth roller 5 below the liquid level in the sump 12. The adjustment device 9 is used to adjust the relative height of the fourth roller 5 relative to the frame 1, while also tightening and correcting the mop belt 8. The filter device 14 is installed within the sump 12 to purify the wastewater and can specifically be a filter plate with a dirt adsorption function. The spray device 13 is installed within the sump 12 and extracts water from the sump 12 to clean the mop belt 8. Specifically, the spray device 13 uses filtered water for an initial cleansing of the mop belt 8, followed by a secondary cleansing of the mop belt 8 using clean water from an external clean water tank 12. A drain outlet 16 is provided at the bottom of the sump 12 to remove deposited debris and sludge.

[0036] Before installing this structure on the mopping machine, the support leg 15 with rollers should be fixed on the frame 1 and its height should be adapted to ensure that the ground surface contacts the mopping belt 8 while not contacting the first roller 2 and the second roller 3.

[0037] During operation, the mop belt 8 between the first and second rollers 2 and 3 contacts the ground surface and, through its relative motion with the ground, removes dirt, cleaning the surface. The dirt-laden mop belt 8 rotates, passing through the second, third, and fourth rollers 3, 4, and 5. Passing the fourth roller 5, it immerses in the sewage in the sump 12, where some dirt is removed. Then, between the fourth and fifth rollers 5 and 6, a spraying device 13 extracts filtered sewage from the filter 14 for a first rinse of the mop belt 8. Then, the spraying device 13 extracts clean water from the clean water tank 12 for a second rinse of the mop belt 8. The mop belt 8 then enters the space between the fifth roller 6 and the squeeze roller 7, where it is squeezed to adjust its moisture content. Finally, it returns to the first roller 2 to clean the ground surface. During the squeeze process, the water expelled from the mop belt 8 falls into the filter 14. Passing the fifth roller 6, it is squeezed by the squeeze roller 7, causing the sewage to fall into the filter 14 for filtration.

[0038] After the mopping machine has been operating for a period of time, it is necessary to open the sewage outlet 16 to discharge the sewage, debris and sludge in the sump 12 .

[0039] Example 2

[0040] Reference Figure 5 As shown, the difference from Example 1 lies in that one roller is omitted in the technical solution of Example 2. Specifically, the second roller 3 is removed and the first roller is moved directly below the water collection trough 12. A cover plate 17 is installed above the entire device as part of the frame 1, and a comb fence 18 is installed between the connection between the adjustment device 9 and the fourth roller 5. The cover plate shields the water collection trough 12 and provides a mounting base for part of the adjustment device 9 and the height adjustment structure of the water squeeze roller 7. The comb fence 18 scrapes filaments and dirt off the mop belt. The cover plate 17 and comb fence 18 can also be used in the solution of Example 1, producing the same effect.

[0041] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
