Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, and more specifically, to a structure for recycling wastewater from a cleaning roller cloth and a floor scrubber. Background Technology

[0002] With the development of technology, more and more smart home appliances are entering our lives. Among them, intelligent robotic vacuum cleaners are one of the most common smart home appliances in modern households. Using machine intelligence to replace manual cleaning and automatically clean the floors of a room is called an intelligent robotic vacuum cleaner. Intelligent robotic vacuum cleaners have evolved from random cleaning and planned cleaning to navigation-based mapping cleaning, and now to the three-in-one function of vacuuming, sweeping, and mopping. Their functions include sweeping, vacuuming, and mopping, making them an essential floor cleaning tool for modern homes, offices, and other spaces.

[0003] Some existing sweepers include a roller cloth, a water spraying mechanism for spraying water onto the roller cloth, and a recycling mechanism for collecting wastewater from the roller cloth. The recycling mechanism includes a scraper, a wastewater trough, and a wastewater pump. The scraper scrapes the wastewater from the roller cloth into the wastewater trough, and then the wastewater pump pumps it into the wastewater chamber of the sweeper. In order to collect the wastewater scraped off the roller cloth by the scraper, the wastewater trough needs to be set to be equal to or similar in length to the scraper. Longer wastewater troughs are more difficult to manufacture and have a more complex structure, resulting in higher production costs. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a wastewater recovery structure for a cleaning roller cloth, suitable for installation on a machine body. The machine body has a mop roller at its bottom, and a roller cloth is attached to the outer circumference of the mop roller. The wastewater recovery structure includes a wastewater recovery mechanism for recovering wastewater from the roller cloth. This mechanism includes a scraper, a wastewater extraction trough, a wastewater extraction device, and a wastewater chamber. The wastewater extraction trough is located above the scraper and communicates with the wastewater extraction device. The scraper abuts against the roller cloth. When the mop roller rotates, the scraper scrapes the wastewater from the roller cloth to its upper side, guiding the wastewater along its extension direction to the wastewater extraction trough. The wastewater extraction device extracts the wastewater from the wastewater extraction trough into the wastewater chamber. This wastewater recovery structure for a cleaning roller cloth, equipped with a water spraying mechanism and a wastewater recovery mechanism, can automatically clean the mop cloth while cleaning the floor, preventing secondary pollution of the floor due to untimely mop cleaning, improving cleaning efficiency, and providing a superior user experience.

[0005] Optionally, a receiving space for accommodating sewage is formed between the upper side of the scraper and the machine body, and the part of the roller cloth that contacts the scraper is the contact part. When the mop roller rotates, the contact part scrapes downward relative to the scraper.

[0006] Optionally, the receiving space is a groove provided on the upper side of the scraper, and the receiving space is provided with a guide slope near the inner groove wall of the roller cloth.

[0007] Optionally, the lower part of the sewage extraction tank extends to the bottom of the inner groove, and the machine body is provided with a connecting cavity for connecting the sewage extraction tank and the sewage extraction device.

[0008] Optionally, the scraper is elongated and extends along the axial direction of the mop roller. A baffle is provided on the machine body, and the baffle is connected to one end of the scraper. The receiving space is formed on one side of the baffle, and the sewage extraction tank is located at the end of the receiving space away from the baffle.

[0009] Optionally, the scraper bar has a toothed portion on the side near the roller cloth, the toothed portion being used to scrape water against the roller cloth; the toothed portion includes a first inclined surface and a second inclined surface, the included angle between the first inclined surface and the second inclined surface being 60°-120°.

[0010] Optionally, a reinforcing rib is provided between the lower side of the scraper and the machine body.

[0011] Optionally, the wastewater recovery structure for the washing roller cloth further includes a water spraying mechanism for spraying water to clean the roller cloth. The water spraying mechanism includes a water tank, a clean water pump, and a water spray nozzle.

[0012] Optionally, multiple water spray nozzles are provided along the axial direction of the mop roller, and the water spray nozzles are located on the lower side of the scraper; the water tank is detachably mounted on the machine body, the wastewater chamber is located on the water tank, and the water tank is provided with a clean water chamber separated from the wastewater chamber, the clean water chamber being used to store the clean water.

[0013] Compared to existing technologies, the wastewater recovery structure for the cleaning roller cloth in this invention is simple in structure and low in production cost. It is equipped with a water spraying mechanism and a wastewater recovery mechanism, which can automatically clean the mop cloth while cleaning the floor, preventing secondary pollution caused by untimely mop cleaning, improving cleaning efficiency, and providing a better user experience. The wastewater is guided to the wastewater extraction tank by the scraper's own structure, allowing for a shorter tank length, reducing manufacturing difficulty, and simplifying the structure. The wastewater extraction tank is located at the end of the containing space away from the baffle wall, ensuring that wastewater in the containing space can only flow along... The scraper guides the wastewater to the sewage extraction tank for discharge, preventing sewage from leaking out of the containment space and becoming unrecoverable, ensuring reliable sewage recovery.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] See Figures 1-13This utility model embodiment provides a structure for recycling wastewater from a cleaning roller cloth, suitable for installation on a machine body 1. A mopping roller 2 is located at the bottom of the machine body 1, and a roller cloth 21 is mounted on the outer circumference of the mopping roller 2. The structure includes a water spraying mechanism for cleaning the roller cloth 21 and a wastewater recycling mechanism for recycling wastewater from the roller cloth 21. The wastewater recycling mechanism includes a scraper 41, a wastewater extraction trough 42, a wastewater extraction device 43, and a wastewater chamber 44. The wastewater extraction trough 42 is located above the scraper 41 and is connected to the wastewater extraction device 43. The scraper 41 abuts against the roller cloth 21, causing the roller cloth 21 to become concave, thereby squeezing out the wastewater from the roller cloth 21. When the mopping roller 2 rotates, the scraper 41 scrapes the wastewater from the roller cloth 21 to its upper side. The scraper 41 guides the wastewater on the upper side along its own length to the wastewater extraction tank 42. The wastewater extraction device 43 then extracts the wastewater from the wastewater extraction tank 42 into the wastewater chamber 44, thereby achieving the function of automatic wastewater recycling. By guiding the wastewater to the wastewater extraction tank 42 through the structure of the scraper 41 itself, the length of the wastewater extraction tank 42 can be set to be shorter, reducing processing difficulty and simplifying the structure. The water spraying mechanism and the wastewater recycling mechanism work together to automatically clean the mop 21, achieving the function of cleaning the floor and cleaning the mop 21 at the same time. This utility model has a simple structure and low production cost for cleaning mop and recycling wastewater. It is equipped with a water spraying mechanism and a wastewater recycling mechanism, which can automatically clean the mop while cleaning the floor, avoiding secondary pollution of the floor due to untimely mop cleaning, improving the cleaning effect, and providing a better user experience.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8A receiving space 45 for accommodating sewage is formed between the upper side of the scraper 41 and the machine body 1. The part of the roller cloth 21 that contacts the scraper 41 is the contact part 211. When the mop roller 2 rotates, the contact part 211 scrapes downward (slanted downward or directly downward) relative to the scraper 41 so that the sewage scraped out by the roller cloth 21 can be retained on the upper side of the scraper 41. The receiving space 45 is a groove provided on the upper side of the scraper 41. A guide slope 451 is provided on the inner groove wall of the receiving space 45 near the roller cloth 21 to facilitate the guidance and retention of the sewage scraped out by the scraper 41 in the upper groove. The sewage retained in the groove is guided along the extension direction of the scraper 41 to the sewage extraction tank 42 and is extracted by the sewage extraction device 43. The sewage chamber 44 is used to automatically recycle sewage. The lower part of the sewage extraction tank 42 extends to the bottom of the inner groove to extract sewage from the groove, ensuring thorough sewage extraction. The body 1 is provided with a connecting cavity 12 for connecting the sewage extraction tank 42 and the sewage extraction device 43. The lower opening of the sewage extraction tank 42 is provided with a guide slope 421 for guiding sewage to the connecting cavity 12. The connecting cavity 12 of this invention only needs to buffer the sewage extracted from the shorter sewage extraction tank 42, so the connecting cavity 12 can also be set smaller and the structure is compact. In the prior art, a longer sewage tank requires a correspondingly larger connecting cavity, which occupies a large space and has a higher production cost. Figure 7 In the middle, the mop roller 2 rotates clockwise.

[0034] See Figures 1-3 The scraper 41 is long and extends along the axial direction of the mop roller 2. A baffle 11 is provided on the machine body 1. The baffle 11 is integrally connected to one end of the scraper 41. The accommodating space 45 is formed on one side of the baffle 11. The sewage extraction tank 42 is located at the end of the accommodating space 45 away from the baffle 11, so that the sewage in the accommodating space 45 can only be guided to the sewage extraction tank 42 along the scraper 41 and discharged, avoiding the problem of sewage in the accommodating space 45 leaking out from other parts and not being able to be recycled. The sewage recycling is reliable. A control board is provided on the machine body 1. The control board controls the operation of the clean water pump and the sewage extraction device. The clean water pump intermittently sprays water to wet the cleaning roller cloth. After wetting, the sewage is scraped out and then extracted and recycled by the sewage extraction device.

[0035] See Figure 3 , Figure 4 , Figure 7 and Figure 8The scraper 41 has a toothed portion 412 on the side near the roller cloth 21. The toothed portion 412 is used to press against the roller cloth 21 to scrape water. The scraping effect is good because the toothed portion 412 squeezes the roller cloth 21. The toothed portion 412 includes a first inclined surface 413 and a second inclined surface 414. The included angle A between the first inclined surface 413 and the second inclined surface 414 is 60°-120°. In this embodiment, the included angle A is a right angle or close to a right angle. The included angle A should not be set too small, which would cause the toothed portion 412 to be too sharp and puncture the roller cloth 21. The included angle A should also not be set too large, which would cause the problem of poor squeezing and scraping effect on the roller cloth 21.

[0036] See Figures 1-3 A reinforcing rib 415 is provided between the lower side of the scraper 41 and the machine body 1. Multiple reinforcing ribs are provided along the extension direction of the scraper 41 to increase its strength, making it less susceptible to deformation under pressure from the roller cloth 21, thus ensuring reliable water removal. If the scraper 41 is not strong enough and is deformed under pressure, the water removal effect will be poor. The water spraying mechanism includes a water tank 31, a clean water pump 32, and a spray nozzle 33. The inlet of the clean water pump 32 is connected to the water tank 31 via a pipeline, and the outlet of the clean water pump 32... It is connected to the water nozzle 33 through a pipeline; the clean water pump 32 is used to transport the clean water in the water tank 31 to the water nozzle 33 and spray it towards the roller cloth 21 to clean the roller cloth 21; the clean water sprayed onto the roller cloth 21 with dirt will form sewage, and the scraper 41 will scrape this sewage away from the roller cloth 21 to realize the function of automatically cleaning the roller cloth 21 and recycling sewage; the sewage extraction device is the sewage pump 43, and can also be set as other structures such as air bag, air pump, etc. to provide suction.

[0037] See Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13Multiple water spray nozzles 33 are arranged along the axial direction of the mop roller 2, making the water spray on the roller cloth 21 more even and improving the cleaning effect. The water spray nozzles 33 are located on the lower side of the scraper 41. The wastewater scraped off the roller cloth 21 by the scraper 41 is retained on the upper side of the scraper 41. The part of the roller cloth 21 that rotates to the water spray nozzle 33 is the relatively clean part after the wastewater has been scraped off. At this time, water is sprayed to wet the clean part. The wetted part is rotated to contact the ground to realize the mopping function. The water tank 31 is detachably installed on the machine body 1, and the wastewater chamber 44 is installed on the water tank 31. The water tank 31 is equipped with a clear water chamber 311, which is separated from the sewage chamber 44. The clear water chamber 311 is used to store clear water. Clear water and sewage are stored through two chambers (clear water chamber and sewage chamber) of a water tank. The structure is compact, and it is easy to pour out sewage and add clear water after the water tank is disassembled. The water tank 31 is equipped with a sewage inlet valve 5, and the body 1 is equipped with a sewage inlet 312 connected to the sewage extraction device 43. The sewage inlet valve 5 includes a first spring 50, a first valve core 51, and a sewage outlet 52 connected to the sewage chamber 44. After the water tank 31 is removed, the first spring 50 drives the first valve core 51. A valve core 51 is closed downwards to prevent sewage leakage. The machine body 1 is equipped with a first guide post 13 for upward opening of the first valve core 51. When the water tank 31 is installed on the machine body 1, the first valve core 51 is opened by the first guide post 13 to connect the sewage outlet 52 with the sewage inlet 312. At this time, the sewage extraction device 43 works to extract the sewage scraped by the roller cloth into the sewage chamber 44. A clean water outlet valve 6 is provided on the water tank 31, and a clean water outlet 313 connected to the clean water pump 32 is provided on the machine body 1. The clean water outlet valve 6 includes a second spring 60, a second valve core 61, and a connection to the clean water pump 32. The water chamber 311 is connected to the clean water extraction pipe 63. One end of the clean water extraction pipe 63 is connected to the bottom of the clean water chamber 311. After the water tank 31 is removed, the second spring 60 drives the second valve core 61 to close downwards to prevent the leakage of clean water. The machine body 1 is provided with a second guide post 14 for opening the second valve core 61. When the water tank 31 is installed on the machine body 1, the second valve core 61 is opened by the second guide post 14 so that the clean water extraction pipe 63 is connected to the clean water outlet 313. At this time, the clean water pump 32 works to extract the clean water in the clean water chamber 311 and spray it onto the roller cloth from the spray nozzle 33 for cleaning.

[0038] This utility model features a wastewater recovery structure for a cleaning roller cloth, equipped with a water spraying mechanism and a wastewater recovery mechanism. It automatically cleans the mop cloth while cleaning the floor, preventing secondary pollution caused by untimely mop cleaning, improving cleaning efficiency, and providing a superior user experience. The wastewater extraction tank is located at the end of the containing space away from the baffle, ensuring that wastewater in the containing space can only be discharged through the extraction tank along the scraper blade, preventing leakage and ensuring reliable wastewater recovery. The scraper blade has protruding teeth on the side near the roller cloth, which compress the roller cloth for effective water scraping. Reinforcing ribs are installed between the lower side of the scraper blade and the machine body, with multiple ribs extending along the blade's direction, increasing its strength and preventing deformation from the roller cloth, thus ensuring reliable water scraping. A water tank with two chambers stores clean water and wastewater, resulting in a compact structure. The water tank can be disassembled for easy emptying of wastewater and addition of clean water.
