[0033] The floor sweeping robot has practical functions such as self-cleaning, automatic water washing of the mop, drying of the mop, and automatic water replenishment for the main machine to continue the journey. In the related art, the base station cleans the mop through a self-cleaning tray with a built-in cleaning mop.

[0034] However, when the self-cleaning tray cleans the mop, stains will accumulate in the self-cleaning tray, which is not convenient for cleaning.

[0035] Please refer to Figure 1 and Figure 2 , a cleaning tank structure 10 according to an embodiment of the present utility model includes a cleaning tank 12 and a squeegee. The squeegee protrudes from the bottom surface of the cleaning tank 12. The squeegee includes a first portion 15 and a second portion 16. Compared with the bottom surface of the cleaning tank 12, the height of the second portion 16 is greater than the height of the first portion 15.

[0036] The cleaning tank structure 10 is configured such that when the mopping cloth is placed in the cleaning tank 12, the mopping cloth contacts the first part 15, the second part 16, and the bottom surface of the cleaning tank 12.

[0037] In the above-mentioned cleaning tank structure 10, the second part 16 is used to clean the mopping cloth, and the first part 15 can reduce the lifting height of the mopping cloth, to a certain extent reducing the gap between the mopping cloth and the bottom surface of the cleaning tank 12, so that the cleaning effect of the mopping cloth on the bottom surface of the cleaning tank 12 is good, and the accumulation of stains on the bottom surface of the cleaning tank 12 is reduced.

[0038] Specifically, the cleaning tank structure 10 is arranged in the base station for cleaning the mopping cloth of the cleaning robot.

[0039] The cleaning robot includes a body and a mopping cloth. The mopping cloth is installed at the bottom of the body. When the mopping cloth of this embodiment rotates, its rotation axis is substantially perpendicular to the bottom surface of the body.

[0040] When the cleaning tank structure 10 is provided with a single cleaning tank 12, it can be used in matching with a cleaning robot having a single mopping cloth. The single mopping cloth can rotate in the cleaning tank 12 in the clockwise direction or the counterclockwise direction, and the present utility model does not make specific limitations thereto.

[0041] When the cleaning tank structure 10 is provided with two cleaning tanks 12, it can be used in matching with a cleaning robot having two mopping cloths.

[0042] The rotation directions of the two mopping cloths respectively placed in the two cleaning tanks 12 during cleaning can be the same or different. In one embodiment, the mopping cloth placed in the left cleaning tank 12 can rotate in the clockwise direction, and the mopping cloth placed in the right cleaning tank 12 can rotate in the clockwise direction. In one embodiment, the mopping cloth placed in the left cleaning tank 12 can rotate in the counterclockwise direction, and the mopping cloth placed in the right cleaning tank 12 can rotate in the clockwise direction. The present utility model does not make specific limitations thereto.

[0043] The cleaning tank structure 10 includes a cleaning tank 12 and a scraping strip. The scraping strip protrudes from the bottom surface of the cleaning tank 12. The mopping cloth rotates in the cleaning tank 12 and contacts the first part 15, the second part 16 of the scraping strip, and the bottom surface of the cleaning tank 12.

[0044] The mopping cloth contacts the scraping strip. Since the scraping strip protrudes from the bottom surface of the cleaning tank 12 and is higher than the bottom surface of the cleaning tank 12, when the mopping cloth contacts the bottom surface of the cleaning tank 12, the contact pressure between the mopping cloth and the scraping strip is greater, and the scraping strip can scrape the surface of the mopping cloth when the mopping cloth rotates.

[0045] At the same time, the mopping cloth contacts the bottom surface of the cleaning tank 12, and can clean the bottom surface of the cleaning tank 12 when the mopping cloth rotates.

[0046] Since the squeegee strip is higher than the bottom surface of the cleaning tank 12, when the mop is placed in the cleaning tank 12, due to the interference of the squeegee strip, the mop cannot contact the bottom surface of the cleaning tank 12 at the positions around the squeegee strip, thus creating a cleaning dead zone at these positions.

[0047] Compared with the bottom surface of the cleaning tank 12, the height of the second part 16 is greater than the height of the first part 15. The second part 16 of the squeegee strip can be used to clean the mop, while the height of the first part 15 of the squeegee strip is reduced compared to the first part 15, enabling the mop to contact the bottom surface of the cleaning tank 12 at the positions around the first part 15 of the squeegee strip, thereby reducing the cleaning dead zone and ensuring the cleanliness of the bottom surface of the cleaning tank 12.

[0048] In summary, while the mop is being cleaned in the cleaning tank 12, it can contact and clean the bottom surface of the cleaning tank 12, to a certain extent avoiding the generation of cleaning dead zones on the bottom surface of the cleaning tank 12 during the cleaning of the mop.

[0049] Please refer to Figure 1 and Figure 2 , in some embodiments, the squeegee strip includes a first squeegee strip 14a and a second squeegee strip 14b. The first squeegee strip 14a and the second squeegee strip 14b are arranged at intervals. Along the rotation direction of the mop, the second part 16 of the second squeegee strip 14b is arranged behind the first part 15 of the first squeegee strip 14a, and the second part 16 of the first squeegee strip 14a is arranged behind the first part 15 of the second squeegee strip 14b.

[0050] In this way, the two squeegee strips clean the mop simultaneously, which is conducive to improving the cleaning efficiency.

[0051] Specifically, the first squeegee strip 14a and the second squeegee strip 14b are arranged at intervals. When the mop is in the cleaning tank, the second parts 16 of the first squeegee strip 14a and the second squeegee strip 14b clean the mop simultaneously. After the mop rotates half a circle, the first squeegee strip 14a and the second squeegee strip 14b can perform a full-area cleaning of the mop once. Thus, the cleaning efficiency of the mop can be improved.

[0052] Furthermore, the first part 15 of the first squeegee strip 14a is arranged opposite to the second part 16 of the second squeegee strip 14b, that is, along the rotation direction of the mop, as Figure 3 shown, when the mop rotates counterclockwise (direction R2) in the left cleaning tank, the second part 16 of the second squeegee strip 14b is arranged behind the first part 15 of the first squeegee strip 14a, and the second part 16 of the first squeegee strip 14a is arranged behind the first part 15 of the second squeegee strip 14b.

[0053] Compared with the bottom surface of the cleaning tank 12, the height of the second part 16 is greater than that of the first part 15, so that the height at which the mop contacts the first part 15 is reduced, and the contact pressure between the mop and the second part 16 is relatively greater, enabling the second part 16 to better clean the mop.

[0054] Please refer to Figure 1 , in some embodiments, the first squeegee 14a, the second squeegee 14b and the bottom surface of the cleaning tank 12 enclose a diversion channel 18. The cleaning tank structure 10 includes a drainage channel 20, a water inlet hole 22 and a water outlet hole 24. The water inlet hole 22 is connected to the water outlet hole 24 through the diversion channel 18 and the drainage channel 20 in sequence.

[0055] In this way, the diversion channel 18 can guide the sewage in the cleaning tank 12 to flow to the drainage channel 20 and flow out from the drainage channel 20, preventing the sewage from accumulating in the cleaning tank 12.

[0056] Specifically, the diversion channel 18 is connected to the drainage channel 20. The water inlet hole 22 is arranged on one side of the diversion channel 18, the other side of the diversion channel 18 is connected to the drainage channel 20, and the water outlet hole 24 is connected to the drainage channel 20.

[0057] The clean water flows from the water inlet hole 22 to the diversion channel 18. The mop is wetted by the clean water above the squeegee. The mop rotates and directly contacts the squeegee, enabling the squeegee to clean the mop. The second part 16 scrapes off the dirt and sewage on the mop together. Most of the sewage flows to the diversion channel 18 and then is discharged from the water outlet hole 24 through the drainage channel 20. In this way, the sewage can be prevented from remaining in the cleaning tank 12 to pollute the mop, achieving a better cleaning effect.

[0058] Please refer to Figure 1 , in one embodiment, the cleaning tank structure 10 further includes a water inlet channel 23. The water inlet channel 23 is connected to the second water inlet hole 22 and the diversion channel 18, and is used to divert the clean water flowing out of the second water inlet hole 22 into the cleaning tank 12. The structure of the water inlet channel 23 can be set according to the spatial layout of the base station and the cleaning tank structure 10, so that the cleaning tank structure 10 can be applicable to base stations of different volumes and designs.

[0059] Please refer to Figure 3 and Figure 4 , in some embodiments, the second part 16 forms a scraping surface 26 for cleaning the mop, and the rotation direction of the mop is opposite to the orientation of the scraping surface 26.

[0060] In this way, after the squeegee scrapes off the sewage on the mop, the sewage can directly flow into the diversion channel 18.

[0061] Specifically, the second part 16 has a scraping surface 26 that contacts and scrapes the mop. As Figure 4As shown, the facing direction of the scraping surface 26 for cleaning the mop of the second part 16 is opposite to the rotation direction of the mop, that is, when the mop rotates, it can contact the top of the scraping surface 26. When the top of the scraping surface 26 contacts the mop, there is a large frictional force, so as to achieve a better cleaning effect.

[0062] Furthermore, when the scraping strip includes a first scraping strip 14a and a second scraping strip 14b, a diversion channel 18 is formed by the first scraping strip 14a, the second scraping strip 14b and the bottom surface of the cleaning tank 12. The scraping surface 26 is arranged facing the diversion channel 18, and the rotation direction of the mop is opposite to the facing direction of the scraping surface 26. After the sewage on the mop is scraped off by the scraping strip, the sewage can directly flow into the diversion channel 18.

[0063] When the first scraping strip 14a and the second scraping strip 14b are arranged in the cleaning tank 12, as Figure 2 and Figure 3 shown, the first part 15 of the first scraping strip 14a and the second part 16 of the second scraping strip 14b are oppositely arranged on both sides of the diversion channel 18, and the second part 16 of the first scraping strip 14a and the first part 15 of the second scraping strip 14b are oppositely arranged on both sides of the diversion channel 18.

[0064] The rotation direction of the mop is opposite to the facing direction of the scraping surface 26. Taking the cleaning tank 12 on the left in Figure 2 as an example, the mop rotates counterclockwise in the cleaning tank 12, first passes through the first part 15 of the first scraping strip 14a, and then passes through the second part 16 of the second scraping strip 14b. When the mop passes through the first part 15 of the first scraping strip 14a, the dirt in the cleaning tank 12 can be brought into the diversion channel 18. When the mop passes through the second part 16 of the second scraping strip 14b, the dirt and sewage attached to the mop can be directly scraped off by the second part 16 and fall into the diversion channel 18.

[0065] After passing through the second part 16 of the second scraping strip 14b, the mop is relatively clean. At this time, the mop continues to rotate counterclockwise, and can clean the lower half of the bottom surface of the cleaning tank 12. When passing through the first part 15 of the second scraping strip 14b, the dirt falls into the diversion channel 18 from the first part 15 of the second scraping strip 14b.

[0066] Subsequently, the mop passes through the second part 16 of the first scraping strip 14a, and the dirt and sewage attached to the mop are scraped off and fall into the diversion channel 18. The mop continues to rotate counterclockwise, and can clean the upper half of the bottom surface of the cleaning tank 12. After the above actions are repeated many times, both the mop and the cleaning tank 12 can be cleaned.

[0067] At the same time, since the water flow rate in the diversion channel 18 is large, the diversion channel 18 can be flushed, so that it is not easy for dirt to remain and accumulate in the diversion channel 18.

[0068] In summary, while the mop is being cleaned in the cleaning tank 12, the bottom surface of the cleaning tank 12 can be cleaned, keeping the bottom surface of the cleaning tank 12 relatively clean. On the one hand, it is not easy to contaminate the mop after cleaning; on the other hand, it enables users not to frequently clean the cleaning tank 12.

[0069] Please refer to Figure 4 , in some embodiments, the diversion channel 18 includes a first section 28 and a second section 30 that are connected to each other in the direction from the water inlet hole 22 to the drainage channel 20, and the slope of the bottom surface of the first section 28 is smaller than the slope of the bottom surface of the second section 30.

[0070] In this way, the small slope of the bottom surface of the first section 28 is conducive to accumulating clear water to moisten the mop, and the large slope of the bottom surface of the second section 30 is conducive to quickly diverting the sewage to the drainage channel 20.

[0071] Specifically, the first section 28 of the diversion channel 18 is connected to the water inlet hole 22, and the water inlet hole 22 injects purified water into the diversion channel 18. The slope of the bottom surface of the first section 28 is smaller. After the purified water flows into the first section 28, the flow rate is relatively slow, so that the purified water can fully contact the mop and moisten the mop. The sewage scraped off by the second part 16 of the squeegee flows into the diversion channel 18 after contacting the mop. The slope of the bottom surface of the second section 30 is large, and the sewage can be quickly diverted to the drainage channel 20.

[0072] Furthermore, the slope of the bottom surface of the second section 30 is large, and the flow rate of the water in the second section 30 is fast. In this way, the water has a scouring effect on the inner wall of the second section 30 of the diversion channel 18, and to a certain extent, it can maintain the cleanliness of the diversion channel 18.

[0073] Please refer to Figure 4 , in some embodiments, the horizontal height h1 of the bottom surface of the drainage channel 20 on the side close to the diversion channel 18 is greater than the horizontal height h2 of the drainage channel 20 on the side close to the water outlet hole 24.

[0074] In this way, the diversion effect of the drainage channel 20 is good.

[0075] Specifically, the drainage channel 20 gradually decreases along the direction from the diversion channel 18 to the water outlet hole 24, which is conducive to the water approaching the water outlet hole 24 under the action of gravity. In this way, the drainage channel 20 can have a drainage effect on the sewage and is conducive to guiding the sewage to the water outlet hole 24.

[0076] Furthermore, the bottom surface of the drainage channel 20 is V-shaped or U-shaped, and the horizontal height at the middle position of the bottom surface of the drainage channel 20 is lower than the horizontal heights at the two side positions of the bottom surface of the drainage channel 20. In this way, the drainage channel 20 can have a better drainage effect on the sewage.

[0077] Please refer to Figure 4, in some embodiments, the horizontal height h3 of the bottom surface of the diversion channel 18 on the side close to the water inlet hole 22 is greater than the horizontal height h4 of the diversion channel 18 on the side close to the drainage channel 20.

[0078] In this way, the diversion channel 18 is inclined, which is conducive to guiding the water flow to the drainage channel 20 and the water outlet hole 24.

[0079] Specifically, after the purified water flows into the cleaning tank 12 from the water inlet hole 22, most of the purified water is absorbed by the mop in the cleaning tank 12, and a small part of the purified water flows to the drainage channel 20. During the process of cleaning the mop, the purified water becomes sewage after contacting the dirt on the mop, and is scraped off the mop by the second part 16 and flows into the diversion channel 18.

[0080] Since the horizontal height h3 of the bottom surface of the diversion channel 18 on the side close to the water inlet hole 22 is greater than the horizontal height h4 of the diversion channel 18 on the side close to the drainage channel 20, the sewage can spontaneously flow to the drainage channel 20 by gravity, avoiding the sewage from accumulating in the cleaning tank 12 and polluting the mop.

[0081] Please refer to Figure 2 and Figure 4 , in some embodiments, the cleaning tank structure 10 includes a filter member 32. The filter member 32 surrounds the periphery of the water outlet hole 24, and the filter member 32 is provided with through holes 33 to communicate the water outlet hole 24 and the drainage channel 20.

[0082] In this way, the filter member 32 can filter solid dirt and prevent the water outlet hole 24 from being blocked.

[0083] Specifically, the filter member 32 surrounds the periphery of the water outlet hole 24, and can filter the sewage flowing to the water outlet hole 24. The sewage may carry some hairs and solid dirt. The filter member 32 is provided with through holes 33 to communicate the water outlet hole 24 and the drainage channel 20. The sewage and small solid dirt can pass through the through holes 33 and be discharged from the water outlet hole 24. Some larger solid dirt can be intercepted by the filter member 32 outside the water outlet hole 24, avoiding the accumulation of larger solid dirt from blocking the water outlet hole 24 and causing a large amount of sewage to accumulate in the water outlet hole 24 and the drainage channel 20, and the sewage overflows from the cleaning tank 12 due to the inability to discharge the sewage.

[0084] Please refer to Figure 1 , in some embodiments, the cleaning tank structure 10 includes a retaining strip 34. The retaining strip 34 surrounds at least part of the drainage channel 20 to isolate the cleaning tank 12 and at least part of the drainage channel 20.

[0085] In this way, the retaining strip 34 can isolate the sewage from the cleaning tank 12 and prevent the sewage from flowing back into the cleaning tank 12.

[0086] Specifically, the retaining bar 34 surrounds one side of the drainage channel 20 close to the water outlet hole 24. When the sewage flows from the drainage channel 20 to the water outlet hole 24, the sewage can be cached in the area enclosed by the retaining bar 34 and the side wall of the drainage channel 20, waiting to be filtered. In this way, the capacity of the drainage channel 20 to hold sewage can be improved, preventing the sewage from flowing back into the cleaning tank 12 and overflowing from the cleaning tank 12.

[0087] Please refer to Figure 1 , in some embodiments, the cleaning tank structure 10 includes a liquid level detection device 36. The liquid level detection device 36 is arranged in the drainage channel 20 and is configured to send an alarm message when the water level in the drainage channel 20 reaches a preset height.

[0088] In this way, the sewage in the drainage channel 20 is detected. After the sewage accumulates to a certain extent, an alarm signal is triggered to prevent the sewage from overflowing.

[0089] Specifically, when the sewage flows from the drainage channel 20 to the water outlet hole 24, the sewage can be temporarily stored in the sewage caching area enclosed by the side wall of the drainage channel 20. The liquid level detection device 36 is arranged in the drainage channel 20 and sends an alarm message when the water level in the drainage channel 20 reaches a preset height.

[0090] Under the normal drainage capacity of the water outlet hole 24, the water level in the drainage channel 20 is lower than the preset height. Therefore, whether the water outlet hole 24 is blocked can be detected by the water level condition in the drainage channel 20. When the water level in the drainage channel 20 reaches the preset height, it can be considered that the water outlet hole 24 is blocked.

[0091] Optionally, the liquid level detection device 36 is arranged on the side wall of the drainage channel 20 close to the water outlet hole 24. The liquid level detection device 36 includes electrode plates, and the electrode plates include two independent electrodes. The two electrodes are placed at different heights on the side wall of the drainage channel 20. One of the electrodes is located at the preset height on the side wall, and the other electrode is located at the bottom of the drainage channel 20. If the sewage in the drainage channel 20 reaches the preset height, the two electrodes are conducted. At this time, the current in the circuit for detecting the water level changes, so that the liquid level detection device 36 can send an alarm message.

[0092] Optionally, the liquid level detection device 36 is arranged in the sewage caching area enclosed by the side wall of the drainage channel 20. The liquid level detection device 36 includes a float, and the float is placed in the sewage caching area. When the water level in the drainage channel 20 rises, the float rises accordingly. The liquid level detection device 36 can obtain the water level height in the drainage channel 20 by acquiring the rising height of the float.

[0093] In one embodiment, when the liquid level detection device 36 issues an alarm message, the base station stops supplying water to the cleaning tank 12. This can prevent water from overflowing from the cleaning tank 12 to the base station and the ground due to continuous water inflow into the cleaning tank 12 when the water outlet hole 24 is blocked.

[0094] In summary, the height of the second part 16 of the squeegee is greater than that of the first part 15. The second part 16 is used to clean the mop, and the first part 15 can reduce the lifting height of the mop, thereby reducing the gap between the mop and the bottom surface of the cleaning tank 12 to a certain extent. This can ensure good cleaning effect of the bottom surface of the cleaning tank 12 by the mop and reduce the accumulation of stains on the bottom surface of the cleaning tank 12.

[0095] Please refer to Figure 5 and Figure 6 A base station according to an embodiment of the present invention includes the cleaning tank structure 10 of any of the above embodiments.

[0096] In the above base station, the second part 16 is used to clean the mop, and the first part 15 can reduce the lifting height of the mop, thereby reducing the gap between the mop and the bottom surface of the cleaning tank 12 to a certain extent. This can ensure good cleaning effect of the bottom surface of the cleaning tank 12 by the mop and reduce the accumulation of stains on the bottom surface of the cleaning tank 12.

It can be understood that the cleaning tank structure 10 can be provided not only in the base station but also on other devices for cleaning components of other devices.

[0099] In the illustrated embodiment, the cleaning tank structure 10 can be used in cooperation with a double-rotary cleaning robot. After the cleaning is completed, the cleaning robot can return to the base station, place the mop in the cleaning tank 12 for cleaning, and at the same time, the base station can also perform operations such as charging and dust collection on the cleaning robot. After the mop of the cleaning robot is cleaned or the cleaning robot is charged, the cleaning robot can leave the base station to continue the cleaning work or stay at the base station until waiting for the next cleaning instruction.

[0100] Please refer to Figure 5 and Figure 6 , in some embodiments, the base station includes a mounting seat 40, and the cleaning tank structure 10 is detachably mounted on the mounting seat 40.

The user can take out the cleaning tank structure 10 from the base station for cleaning. In this way, it is more convenient to clean the cleaning tank structure 10, and it also avoids the accumulation of dirt in the cleaning tank structure 10 due to incomplete cleaning, which affects the cleaning effect of the mop.

[0103] In one embodiment, as Figure 5 shown, the cleaning tank structure 10 includes a handle 44, and the mounting base 40 includes an avoidance groove 46. When the cleaning tank structure 10 is clamped in the receiving groove 42, the handle 44 is located above the avoidance groove 46. When the user needs to take out the cleaning tank structure 10, the cleaning tank structure 10 can be taken out of the base station by applying an upward force by holding the handle 44. The avoidance groove 46 facilitates the user to hold the handle 44.
