[0040] Please refer to Figure 1 and Figure 2 A cleaning tank structure 100 according to an embodiment of the utility model includes a base 10, a drainage structure 22 and a scraper bar 26. A cleaning tank 12 is provided in the base 10. The bottom surface of the cleaning tank 12 includes a spiral surface 14. The spiral surface 14 includes a starting end 16 and a terminal end 18 arranged along the spiral direction of the spiral surface 14. The drainage structure 22 is connected to the terminal end 18. The scraper bar 26 is located in the cleaning tank 12, and the scraper bar 26 is connected to the starting end 16. The cleaning tank structure 100 is configured such that when a mop is placed on the scraper bar 26, the spiral surface 14 contacts the mop, and the spiral direction of the spiral surface 14 is consistent with the rotation direction of the mop.

[0041] In the above-mentioned cleaning tank structure 100, when the mop is placed on the scraper bar 26, the moving mop contacts the spiral surface 14, and the rotation direction of the mop can be consistent with the spiral direction of the spiral surface 14. Therefore, in the process of cleaning the mop, the mop can clean the spiral surface 14 from the starting end 16 to the ending end 18, and then the debris can be discharged into the drainage structure 22, thereby avoiding or reducing the debris remaining on the spiral surface 14, thereby avoiding the cleaning tank structure 100 from stinking or reducing the chance of the cleaning tank structure 100 stinking.

[0042] Combination Figure 6 In some embodiments, the cleaning tank structure 100 includes a base 10 , and a cleaning tank 12 is disposed in the base 10 .

[0043] Specifically, in Figure 1 In the embodiment, the base 10 may be similar to a long plate. Two cleaning tanks 12 may be arranged in the base 10, and the side walls of the two cleaning tanks 12 may be connected to each other, and the two cleaning tanks 12 are connected to each other. Each cleaning tank 12 may also be arranged independently. Two scraping strips 26 are arranged in each cleaning tank 12, and the two scraping strips 26 may be arranged at intervals.

[0044] Combination Figure 1 and Figure 6 , the cleaning tank 12 may be similar to a circular shape, and may be adapted to a circular mop, so that the mop can be cleaned in the cleaning tank 12. It can be understood that in one embodiment, when the rotation center of the mop remains unchanged, no matter the shape of the mop is a triangle, a quadrilateral or other polygon, the cleaning tank 12 may be set to be similar to a circular shape to match the mop. In another embodiment, when the rotation center of the mop changes, the cleaning tank 12 may be irregularly shaped, but the cleaning tank 12 matches the mop, so that the mop can be cleaned in the cleaning tank 12.

[0045] When the cleaning tank structure 100 is provided with only one cleaning tank 12, it can be matched with a cleaning robot with a mop. Figure 1 When the cleaning tank structure 100 is only provided with a cleaning tank 12 near the left side of the cleaning tank structure 100, a mop can rotate in the cleaning tank 12 along the counterclockwise direction R2. When the cleaning tank structure 100 is only provided with a cleaning tank 12 near the right side of the cleaning tank structure 100, a mop can rotate in the cleaning tank 12 along the clockwise direction R1.

[0046] When the cleaning tank structure 100 is provided with two cleaning tanks 12, it can be matched with two cleaning robots with mops. Figure 1 , the mop placed in the cleaning tank 12 near the left side of the cleaning tank structure 100 can rotate in the counterclockwise direction R2, and the mop placed in the cleaning tank 12 near the right side of the cleaning tank structure 100 can rotate in the clockwise direction R1.

[0047] Combination Figure 1 and Figure 2 , along the spiral direction K of the spiral surface 14, the spiral surface 14 may have two ends, one end is a starting end 16, and the other end is a terminal end 18. Along the height direction H of the cleaning tank structure 100, the spiral surface 14 may spirally extend from the upper part of the base 10 to the lower part of the base 10, so that the starting end 16 is close to the upper part of the base 10, the terminal end 18 is close to the lower part of the base 10, and the starting end 16 is located above the terminal end 18. The scraper 26 may be disposed in the cleaning tank 12 and may be connected to the starting end 16. The drainage structure 22 may be disposed in the cleaning tank 12 and may be connected to the terminal end 18. The height direction of the base 10 includes the up and down direction.

[0048] In one embodiment, when the mop of the cleaning robot needs to be cleaned, the mop can be placed on the scraper bar 26, and the cleaning robot can rotate the mop so that the scraper bar 26 scrapes and cleans the mop. While the scraper bar 26 scrapes and cleans the mop, the mop can contact the spiral surface 14, and then in the process of cleaning the mop, the mop can clean the spiral surface 14 from the starting end 16 to the ending end 18, and then the debris can be discharged into the drainage structure 22, so as to avoid or reduce the debris remaining on the spiral surface 14, and then avoid the smell of the cleaning tank structure 100 or reduce the probability of the smell of the cleaning tank structure 100.

[0049] In addition, in the existing water tank cleaning solution, the cleaning effect is not good, and stains will remain on the bottom of the water tank after cleaning, or parts need to be removed for cleaning, and regular cleaning is required, otherwise stains and other debris will accumulate and stink over a long period of time. That is to say, by comparison, in the present cleaning tank structure 100, when the mop is placed on the scraper bar 26, the rotation direction of the mop can be consistent with the spiral direction of the spiral surface 14, and then in the process of cleaning the mop, the mop can clean the spiral surface 14 from the starting end 16 to the ending end 18, and then the debris can be discharged into the drainage structure 22, avoiding or reducing the debris remaining on the spiral surface 14, and then avoiding the smell of the cleaning tank structure 100 or reducing the probability of the cleaning tank structure 100 smelling.

[0050] The cleaning tank structure 100 shown in the figure is provided with two cleaning tanks 12, which can be adapted to a cleaning robot with a double rotating disk cleaning member, and a mop can be provided at the bottom of each rotating disk cleaning member, and the rotating disk cleaning member can drive the mop to rotate, and the mop can be adapted to contact the spiral surface 14. It can be understood that in other embodiments, the cleaning tank structure 100 can also be provided with only one cleaning tank 12, which can be adapted to a cleaning robot with a single rotating disk cleaning member.

[0051] Please combine Figure 1 In some embodiments, the cleaning tank structure 100 includes a water inlet hole 32, at least two scraping bars 26 are provided in the cleaning tank 12, and the two adjacent scraping bars 26 and the bottom surface of the cleaning tank 12 form a water supply channel 34, which connects the water inlet hole 32 and the drainage structure 22.

[0052] In this way, the water inlet 32 ​​can deliver clean water through the water delivery channel 34 , and at the same time, the sewage after cleaning can be discharged from the drainage structure 22 through the water delivery channel 34 .

[0053] Specifically, in Figure 1In the embodiment, along the width direction D of the cleaning tank structure 100, the water inlet hole 32 may be provided at the rear side of the base 10, and two water inlet holes 32 may be provided, and the two water inlet holes 32 are symmetrically arranged. Along the height direction H of the cleaning tank structure 100, the drainage structure 22 is lower than the water inlet hole 32, and the water in the water inlet hole 32 is convenient to flow to the drainage structure 22. The water supply channel 34 may connect the edge of the water inlet hole 32 and the top of the drainage structure 22. The water supply channel 34 may be inclined from the water inlet hole 32 to the drainage structure 22. The width direction of the base 10 includes the front-back direction.

[0054] In one embodiment, the mop can rotate on the scraper bar 26. During the rotation, the mop can be soaked with clean water in the water supply channel 34. The scraper bar 26 can scrape and wash the soaked mop. The wastewater or stains and other debris after scraping and washing can flow into the drainage structure 22 through the water supply channel 34, so that the wastewater can be discharged through the drainage structure 22.

[0055] Please combine Figure 1 In some embodiments, the cleaning tank structure 100 includes a water outlet 36 , which is disposed on the bottom surface of the drainage structure 22 . The drainage structure 22 is provided with a drainage channel 24 , and the water supply channel 34 is connected to the water outlet 36 through the drainage channel 24 .

[0056] In this way, the sewage flowing into the drainage structure 22 can flow away through the water outlet 36 to prevent the sewage from being blocked in the drainage channel 24 .

[0057] Specifically, the water outlet 36 may be rectangular. The water outlet 36 may be provided on the bottom surface of the drainage structure 22, near the rear side of the base 10. The drainage structure 22 is provided with a drainage channel 24, and along the height direction H of the washing tank structure 100, the drainage channel 24 is located below the water supply channel 34. The water supply channel 34 is connected to the drainage channel 24, and the drainage channel 24 is connected to the water outlet 36.

[0058] In one embodiment, sewage and other debris after mopping can flow into the drainage channel 24 through the water supply channel 34. The drainage channel 24 is connected to the water outlet 36, so that the sewage flowing into the drainage structure 22 can flow away through the water outlet 36 to avoid sewage clogging in the drainage channel 24.

[0059] Furthermore, the drainage channel 24 may be inclined from an end away from the water outlet 36 toward an end close to the water outlet 36 , so that the sewage and other debris flowing into the drainage channel 24 can flow faster toward the water outlet 36 .

[0060] Please combine Figure 1 In some embodiments, the bottom surface of the cleaning tank 12 includes a slope 20, and the slope 20 and the spiral surface 14 are respectively located on opposite sides of the scraper 26 along the thickness direction. The slope 20 is set to be inclined downward from the side of the cleaning tank 12 toward the drainage structure 22.

[0061] In this way, when the debris cleaned by the mop falls on the inclined surface 20, the debris can be easily dropped into the drainage structure 22 and discharged.

[0062] Specifically, in Figure 1 In the embodiment, along the thickness direction V of the scraping strip 26, the inclined surface 20 and the spiral surface 14 can be arranged on the opposite sides of the two scraping strips 26, that is, the spiral surface 14 is arranged on the side of one scraping strip 26 opposite to the other scraping strip 26, and the inclined surface 20 is arranged on the side of the other scraping strip 26 opposite to the one scraping strip 26. The spiral surface 14 and the inclined surface 20 can be arranged on both sides of the water supply channel 34 respectively. The inclined surface 20 can be connected to a side of the cleaning tank 12 close to the rear side of the base 10. In one embodiment, during the process of rotating and cleaning, the mop can scrape and wash with a scraping strip 26 close to the inclined surface 20, and the scraped debris can fall on the inclined surface 20. By tilting the inclined surface 20 downward from the side of the cleaning tank 12 to the direction of the drainage structure 22, when the debris cleaned by the mop falls on the inclined surface 20, it is convenient for the debris to fall into the drainage structure 22 and be discharged.

[0063] Please combine Figure 1 , Figure 3 and Figure 4 In some embodiments, the two scrapers 26 that form the water supply channel 34 include a first scraper 28 and a second scraper 30. The first scraper 28 is connected to the starting end 16, and the second scraper 30 is located on the side of the first scraper 28 away from the starting end 16. Compared with the spiral surface 14, the height of the second scraper 30 is lower than the height of the first scraper 28.

[0064] Thus, the first scraper bar 28 is higher so that the debris on the mop can be scraped and washed on the water supply channel 34, which is convenient for draining the debris. The second scraper bar 30 is lower so that the debris on the mop can be scraped and washed on the inclined surface 20, reducing the probability of debris accumulating on the inclined surface 20.

[0065] Specifically, the first scraper bar 28 and the second scraper bar 30 can be disposed in the cleaning tank 12, one end of the first scraper bar 28 and the second scraper bar 30 can be connected to the edge opposite to the water inlet hole 32, and the other ends of the first scraper bar 28 and the second scraper bar 30 can be connected to the top of the drainage structure 22. The second scraper bar 30 is connected to the inclined surface 20.

[0066] Two cleaning grooves 12 are provided on the base 10, which can clean the mop of the cleaning robot with a double rotating disc cleaning member, and each of the double rotating disc cleaning members is provided with a mop. Along the length direction L of the cleaning groove structure 100, a mop can rotate counterclockwise in the cleaning groove 12 near the left side of the base 10. At this time, the counterclockwise rotation direction of the mop is consistent with the spiral direction K of the spiral surface 14 on the left side of the base 10. The first scraper 28 and the second scraper 30 can scrape the mop. Compared with the spiral surface 14, the first scraper 28 is higher, which can make the debris on the mop scraped on the water supply channel 34, thereby facilitating the removal of the debris. The second scraper 30 is lower, which can reduce the debris on the mop scraped on the inclined surface 20, thereby reducing the probability of debris accumulating on the inclined surface 20. It can be understood that along the length direction L of the cleaning tank structure 100, another mop can rotate clockwise in the cleaning tank 12 close to the right side of the base 10. At this time, the clockwise rotation direction of the mop is consistent with the spiral direction K of the spiral surface 14 on the right side of the base 10, so that the debris scraped by the first scraper 28 on the mop falls into the water supply channel 34, and the debris scraped by the second scraper 30 on the mop is reduced to fall on the inclined surface 20.

[0067] exist Figure 1 In the example, the clockwise rotation direction of the mop can be represented by R1, and the counterclockwise rotation direction of the mop can be represented by R2. Figure 4 In the embodiment, the height h2 of the second scraper bar 30 is lower than the height h1 of the first scraper bar 28. When the mop is different, the spiral direction of the spiral surface 14 is different. The spiral direction of the spiral surface 14 near the left side of the base 10 is consistent with R2, and the spiral direction of the spiral surface 14 near the right side of the base 10 is consistent with R1.

[0068] Please combine Figure 1 and Figure 3 In some embodiments, the cleaning tank structure 100 includes a protrusion 38, which is protruded upward on the spiral surface 14 in the axial direction of the spiral surface 14, and the protrusion 38 includes a blocking surface 40 facing the water supply channel 34, and the blocking surface 40 is spaced opposite to the opening of the water supply channel 34.

[0069] In this way, the blocking surface 40 can resist the sewage flowing out of the opening of the water supply channel 34, preventing the sewage from falling on the spiral surface 14 again, thereby avoiding secondary pollution.

[0070] Specifically, in Figure 3In the embodiment, the protrusion 38 may be similar to a cylindrical shape. The protrusion 38 may be convexly arranged on the spiral surface 14 along the axial direction O of the spiral surface 14. A blocking surface 40 may be formed on one side of the protrusion 38 facing the water supply channel 34. The blocking surface 40 is spaced opposite to the opening of the water supply channel 34. The lower end of the blocking surface 40 may be connected to the drainage channel 24. The opening of the water supply channel 34 may be connected to the top of the drainage structure 22. In one embodiment, during the cleaning process of the mop in the cleaning tank 12, the washed sewage may be discharged through the opening of the water supply channel 34. Since the water supply channel 34 is inclined from the water inlet 32 ​​to the drainage structure 22, the flow rate of the sewage flowing out of the opening of the water supply channel 34 is relatively large. There is no obstruction on the opposite side, and the sewage may flow to the spiral surface 14. However, by setting the blocking surface 40, the sewage flowing out of the opening of the water supply channel 34 can be blocked, thereby preventing the sewage from falling on the spiral surface 14 again, thereby avoiding secondary pollution.

[0071] Furthermore, the other side of the protrusion 38 may form a guide surface 42, which may be connected to the spiral surface 14. Sewage and other debris falling on the spiral surface 14 may be guided to flow into the drainage structure 22 through the guide surface 42 to prevent the debris from accumulating on the spiral surface 14. The guide surface 42 may be an arc surface.

[0072] Please combine Figure 1 and Figure 5 In some embodiments, the cleaning tank structure 100 includes a water outlet 36 and a filter 44 . The water outlet 36 is provided on the bottom surface of the drainage structure 22 , and the filter 44 is detachably accommodated in the water outlet 36 .

[0073] In this way, the filter element 44 can filter the sewage to avoid pipe blockage.

[0074] Specifically, in Figure 5 In the embodiment, the bottom of the filter element 44 may be provided with a through hole 46, and the through hole 46 is connected to the water outlet 36. In one embodiment, the sewage and debris after the mop scraping can fall into the drainage channel 24 through the water supply channel 34, the spiral surface 14 or the inclined surface 20, and then flow into the water outlet 36 through the drainage channel 24. The filter element 44 is set in the water outlet 36, and the debris can be left in the filter element 44 at this time, and the sewage can enter the water outlet 36 through the through hole 46 and be discharged, so that the sewage can be filtered to avoid pipe clogging. The debris accumulated in the filter element 44 can be regularly cleaned by disassembling the filter element 44. After cleaning, the filter element 44 is installed in the water outlet 36.

[0075] The number and shape of the through holes 46 are not specifically limited. The number of through holes 46 can be set to multiple, and the shape of the through holes 46 can be set not only to a circle but also to other shapes.

[0076] Please combine Figure 1 and Figure 4 In some embodiments, a handle 48 is provided on the filter element 44 .

[0077] In this way, the filter element 44 can be easily disassembled and assembled.

[0078] Specifically, a handle 48 may be protruded from the top of the filter element 44 along the width direction of the base 10. When the filter element 44 needs to be removed, the handle 48 may be grasped to facilitate the removal of the filter element 44. When the filter element 44 needs to be installed, the handle 48 may be grasped to facilitate the installation of the filter element 44 in the water outlet 36.

[0079] Please combine Figure 1 In some embodiments, the cleaning tank structure 100 includes a baffle 50 , and the baffle 50 and the base 10 form a cleaning tank 12 .

[0080] In this way, the blocking bar 50 can form the side wall of the cleaning tank 12 to ensure that the sewage after cleaning is within the range of the cleaning tank 12 and prevent the sewage from falling into other areas of the base 10.

[0081] Specifically, in Figure 1 In the embodiment, the cleaning tank structure 100 may be provided with an entrance, and the baffle 50 may be installed near the entrance. The baffle 50 may be in an arc shape, and the baffle 50 may form a side wall of the cleaning tank 12, and the baffle 50 and the base 10 may together enclose the cleaning tank 12. In one embodiment, when the mop rotates in the cleaning tank 12 for cleaning, the mop may drive the water to swing, and the baffle 50 may prevent the swinging water from splashing out of the cleaning tank 12, thereby ensuring that the sewage after cleaning is within the range of the cleaning tank 12, and preventing the sewage from falling on other areas of the base 10.

[0082] The material of the baffle bar 50 can be soft rubber, so that the baffle bar 50 has good softness, is easy to deform and can recover the deformation, thereby avoiding interference with the mopping assembly (not shown) of the cleaning robot and thus damaging the cleaning robot.

[0083] In some embodiments, the cleaning tank structure 100 includes a nano-layer (not shown), which is disposed on at least one of the bottom surface of the cleaning tank 12 and the circumferential side surface of the cleaning tank 12 .

[0084] In this way, the hydrophobic and oleophobic properties of the nanolayer can be utilized to reduce the amount of dirt attached to the bottom surface of the cleaning tank 12 and the circumferential side surfaces of the cleaning tank 12 .

[0085] Specifically, in one embodiment, the nano layer can be provided on the bottom surface of the cleaning tank 12. In one embodiment, the nano layer can be provided on the circumferential side surface of the cleaning tank 12, that is, the side surface of the baffle 50 close to the cleaning tank 12 and the side surface of the base 10 close to the cleaning tank 12. In one embodiment, the nano layer can be provided on the bottom surface of the cleaning tank 12 and on the circumferential side surface of the cleaning tank 12.

[0086] The nanolayer has hydrophobic and oleophobic properties. The nanolayer is disposed on the bottom surface of the cleaning tank 12 or the circumferential side of the cleaning tank 12, which greatly reduces the amount of dirt attached to the cleaning tank 12, slows down the odor of sewage, makes the cleaning tank 12 easy to clean, and greatly improves the user experience. The thickness and material of the nanolayer are not specifically limited. Optionally, the nanolayer may include an ultra-thin self-healing hydrophobic coating, and the thickness of the ultra-thin self-healing hydrophobic coating may be less than 100 nm (nanometer).

[0087] The nano-layer significantly improves the cleanliness of the cleaning tank 12, and its acid, alkali and corrosion resistance are not inferior to the surface performance of the raw materials of the cleaning tank 12. Moreover, the coating process of the nano-layer is cheaper than that of the super-hydrophobic coating, which is conducive to reducing costs. The nano-layer can effectively improve the cleanliness of the cleaning tank 12, and dirt is not easy to adhere to the cleaning tank 12, and bacteria are not easy to breed, making the cleaning tank 12 easy to clean and improving the user experience.

The cleaning robot may send the mop into the cleaning tank 12 through the climbing plate 56.

[0091] Please refer to Figure 1 and Figure 7 A cleaning device according to an embodiment of the present utility model includes a cleaning robot and a base station 200 according to any one of the above embodiments.

[0092] In the above cleaning device, when the mop is placed on the scraper bar 26, the moving mop contacts the spiral surface 14, and the rotation direction of the mop can be consistent with the spiral direction of the spiral surface 14. Therefore, in the process of cleaning the mop, the mop can clean the spiral surface 14 from the starting end 16 to the ending end 18, and then the debris can be discharged into the drainage structure 22, thereby avoiding or reducing the debris remaining on the spiral surface 14, thereby avoiding the smell of the cleaning tank structure 100 or reducing the probability of the smell of the cleaning tank structure 100.

[0093] Specifically, the cleaning robot includes a double-turntable cleaning robot and a single-turntable cleaning robot. Figure 1 In the illustrated embodiment, the cleaning tank structure 100 is adapted to a double-turntable cleaning robot. After cleaning, the cleaning robot can return to the base station 200 and place the mop in the cleaning tank 12 for cleaning. The base station 200 can also charge the cleaning robot. After the cleaning robot's mop is cleaned or the cleaning robot is charged, the cleaning robot can leave the base station 200 to continue cleaning, or stay at the base station 200 until waiting for the next cleaning instruction.
