In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0035] The cleaning device includes a cleaning robot and a base station. The cleaning robot is used to walk in the area to be cleaned and perform cleaning work, and can return to the base station for operations such as mopping cloth washing and charging. The intelligent sweeping, washing and mopping integrated robot is particularly favored by users because of its practical functions such as self-cleaning, automatic water washing of the mopping cloth, drying of the mopping cloth, and automatic water replenishment for the main body to continue the journey.

[0036] In the related art, the base station cleans the mopping cloth through a self-cleaning tray with a built-in cleaning mopping cloth. However, when the self-cleaning tray cleans the mopping cloth, it often uses water flow to rinse the mopping cloth, or controls the rotation of the mopping cloth to cooperate with the water flow for cleaning. The solid dirt attached to the mopping cloth cannot be effectively cleaned, resulting in low cleaning efficiency and incomplete cleaning.

[0037] Please refer to Figure 1 and Figure 2 As shown in FIGS. and, a cleaning tank structure 10 provided by an embodiment of the present invention includes a cleaning tank 12 and a cleaning member 14. The cleaning member 14 is located in the cleaning tank 12. The cleaning member 14 includes a scraping portion 16 and a combing portion 18. The scraping portion 16 and the combing portion 18 protrude from the bottom surface of the cleaning tank 12.

[0038] The cleaning tank structure 10 is configured such that when the mopping cloth is placed in the cleaning tank 12, the mopping cloth directly contacts the scraping portion 16 and the combing portion 18, so that the combing portion 18 combs the mopping cloth and the scraping portion 16 scrapes the mopping cloth.

[0039] For the above-mentioned cleaning tank structure 10, when the mopping cloth is cleaned in the cleaning tank 12, the mopping cloth contacts the scraping portion 16 and the combing portion 18, and the mopping cloth directly contacts the scraping portion 16 and the combing portion 18. The combing portion 18 combs the mopping cloth and the scraping portion 16 scrapes the mopping cloth, so that the cleaning of the mopping cloth by the cleaning tank structure 10 is more thorough and the cleaning efficiency is high.

[0040] Specifically, the cleaning tank structure 10 is disposed in the base station 100 for cleaning the mopping cloth of the cleaning robot.

[0041] 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.

[0042] In Figure 2In [the device], the cleaning tank 12 is similar to a circular shape and can be adapted to a mop in a circular shape, so that the mop can be cleaned in the cleaning tank 12. The cleaning tank 12 similar to a circular shape can also be adapted to a mop in a triangular shape. 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 triangular, quadrilateral or other polygons, the cleaning tank 12 can 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 can be in an irregular shape, but the cleaning tank 12 is adapted to the mop so that the mop can be cleaned in the cleaning tank 12.

[0043] When the cleaning tank structure 10 is provided with a single cleaning tank 12, it can be used in combination with a cleaning robot having a single mop. The single mop can rotate in the cleaning tank 12 in a clockwise or counterclockwise direction, and the present invention does not make specific limitations thereon.

[0044] When the cleaning tank structure 10 is provided with two cleaning tanks 12, it can be used in combination with a cleaning robot having two mops. The two mops placed in the two cleaning tanks 12 can rotate in the same direction or different directions during cleaning. In one embodiment, the mop placed in the left cleaning tank 12 can rotate clockwise, and the mop placed in the right cleaning tank 12 can rotate clockwise. In one embodiment, the mop placed in the left cleaning tank 12 can rotate counterclockwise, and the mop placed in the right cleaning tank 12 can rotate clockwise. The present invention does not make specific limitations thereon.

[0045] When the mop of the cleaning robot needs to be cleaned, the cleaning robot can enter the base station 100 for the cleaning process. When the mop is placed on the cleaning tank 12, the mop directly contacts the scraping part 16 and the combing part 18. The cleaning robot drives the mop to rotate, and the cleaning surface of the mop passes through the combing part 18 and the scraping part 16 in sequence in the cleaning tank 12. When the combing part 18 contacts the mop, it can comb the fluff on the surface of the mop. After the fluff is combed to be relatively fluffy, the fluff then passes through the scraping part 16. The scraping part 16 contacts the fluff on the surface of the mop and can scrape off the solid dirt attached to the fluff.

[0046] In some embodiments, along the rotation direction of the mop, the scraping part 16 is arranged behind the combing part 18.

[0047] In this way, the mop first passes through the combing part 18 and then through the scraping part 16, which can improve the cleaning effect and drying efficiency of the mop.

[0048] Specifically, along the rotation direction of the mop, the scraping part 16 is arranged behind the combing part 18, which can ensure that when the mop rotates in the cleaning tank 12, the fluff of the mop first contacts the combing part 18 and then passes through the scraping part 16.

[0049] The combing part 18 combs the mop, which can loosen the fluff of the mop and clean the solid dirt inside the fluff of the mop at the same time. Then the mop passes through the scraping and washing part 16, and the scraping and washing part 16 can scrape and clean the fluff of the mop. In this way, the scraping and washing part 16 can clean the mop more thoroughly. At the same time, after the mop is cleaned, the fluff combed by the combing part 18 is more fluffy and easier to dry in the drying stage. In this way, the cleaning effect of the mop and the drying efficiency can be improved.

[0050] In one embodiment, as Figure 2 shown, the cleaning tank structure 10 includes two cleaning tanks 12. The rotation directions of the two mops in the two cleaning tanks 12 during cleaning are related to the installation positions of the scraping and washing part and the combing part. For example, in combination with Figure 2 , the mop placed in the left cleaning tank 12 rotates counterclockwise, and the mop placed in the right cleaning tank 12 can rotate clockwise. In this way, along the rotation direction of the mop, it can be ensured that when the mop rotates in the cleaning tank 12, the fluff of the mop first contacts the combing part 18 and then passes through the scraping and washing part 16.

[0051] Taking the left cleaning tank 12 as an example, as Figure 2 shown, the left cleaning tank 12 includes a first cleaning member 14a and a second cleaning member 14b. The combing part 18 of the first cleaning member 14a and the scraping and washing part 16 of the second cleaning member 14b are arranged oppositely, and along the rotation direction of the mop (the R2 direction in the figure), the combing part 18 of the first cleaning member 14a is arranged in front of the scraping and washing part 16 of the second cleaning member 14b. The combing part 18 of the second cleaning member 14b is arranged in front of the scraping and washing part 16 of the first cleaning member 14a.

[0052] In other embodiments, as Figure 2 shown, along the rotation direction of the mop (the R2 direction in the figure), the combing part 18 of the first cleaning member 14a is located in front of the scraping and washing part 16 of the first cleaning member 14a, and the combing part 18 of the second cleaning member 14b is located in front of the scraping and washing part 16 of the second cleaning member 14b. In this way, it can also be realized that when the mop rotates in the cleaning tank 12, the fluff of the mop first contacts the combing part 18 and then passes through the scraping and washing part 16.

[0053] In some embodiments, the scraping surface 20 of the scraping and washing part 16 for cleaning the mop faces the direction opposite to the rotation direction of the mop.

[0054] In this way, when the mop rotates, it contacts the scraping surface 20 for cleaning on the scraping and washing part 16, and the cleaning effect is good.

[0055] Specifically, the scraping and washing part 16 has a scraping surface 20 that contacts and scrapes the mop. As Figure 3As shown, the scraping surface 20 of the scrubbing part 16 for cleaning the mop faces in a direction opposite to the rotation direction of the mop, that is, when the mop rotates, it can contact the top of the scraping surface 20. When the top of the scraping surface 20 contacts the mop, there is a large frictional force, so that a better cleaning effect can be achieved.

[0056] In some embodiments, the cleaning member 14 includes a first cleaning member 14a and a second cleaning member 14b. The first cleaning member 14a, the second cleaning member 14b and the bottom surface of the cleaning tank 12 enclose a diversion channel 28. The height of the combing part 18 of the first cleaning member 14a is less than or equal to the height of the scraping part 16 of the second cleaning member 14b, and the height of the combing part 18 of the second cleaning member 14b is less than or equal to the height of the scraping part 16 of the first cleaning member 14a.

[0057] In this way, when the mop is scraped in the cleaning tank 12, the scraping part 16 can clean the mop in the diameter direction of the mop.

[0058] Specifically, the first cleaning member 14a, the second cleaning member 14b and the bottom surface of the cleaning tank 12 enclose a diversion channel 28. The combing part 18 of the first cleaning member 14a and the scraping part 16 of the second cleaning member 14b are arranged opposite to each other, and along the rotation direction of the mop, the combing part 18 of the first cleaning member 14a is arranged in front of the scraping part 16 of the second cleaning member 14b. The combing part 18 of the second cleaning member 14b is arranged in front of the scraping part 16 of the first cleaning member 14a.

[0059] The height of the combing part 18 of the first cleaning member 14a is less than or equal to the height of the scraping part 16 of the second cleaning member 14b, and the height of the combing part 18 of the second cleaning member 14b is less than or equal to the height of the scraping part 16 of the first cleaning member 14a, so that when the mop rotates in the cleaning tank 12, it can contact the scraping part 16 of the first cleaning member 14a and the scraping part 16 of the second cleaning member 14b at the same time.

[0060] Thus, taking the circular mop as an example, when the mop rotates half a circle in the cleaning tank 12, the scraping part 16 of the first cleaning member 14a can clean half of the mop, and the scraping part 16 of the second cleaning member 14b can clean the other half of the mop. The scraping parts 16 of the first cleaning member 14a and the second cleaning member 14b clean the mop in the diameter direction of the mop at the same time. Thus, the cleaning efficiency of the mop can be improved.

[0061] In one embodiment, the combing part 18 includes a plurality of protrusions 22, and the average height of the plurality of protrusions 22 is less than or equal to the height of the scraping part 16 opposite thereto.

[0062] Further, the fluff of the mop first contacts the combing part 18 and then passes through the scraping and washing part 16, so that the scraped water can directly flow into the diversion channel 28 formed by the bottom surface of the cleaning part 14 and the cleaning tank 12.

[0063] Please refer to Figure 2 and Figure 3 , in some embodiments, the combing part 18 includes a plurality of protrusions 22, the scraping and washing part 16 includes a scraping strip 24, and the plurality of protrusions 22 are arranged in two rows along a direction parallel to the length direction of the scraping strip 24, and the two rows of the plurality of protrusions 22 are staggered.

[0064] In this way, the combing part 18 is used to comb the fluff of the mop and clean the inside of the fluff, and the staggered arrangement of the plurality of protrusions 22 makes the combing and cleaning effects better.

[0065] Specifically, the combing part 18 includes a plurality of protrusions 22. When the plurality of protrusions 22 contact the mop, the fluff of the mop can be combed and cleaned. The shape of the protrusions 22 includes, but is not limited to, strip-shaped, cylindrical, conical, prismatic or pyramidal, etc.

[0066] The scraping and washing part 16 includes a scraping strip 24. When the scraping strip 24 contacts the mop, the dirt on the mop can be scraped off together with the sewage, so as to achieve the purpose of cleaning the mop.

[0067] The plurality of protrusions 22 are arranged in two rows along a direction parallel to the length direction of the scraping and washing part 16, that is, the combing part 18 and the scraping and washing part 16 can be located on a straight line or arranged in parallel. The two rows of protrusions 22 are staggered, which can improve the combing effect of the protrusions 22.

[0068] In one embodiment, as Figure 3 shown, the protrusion 22 is conical, and the top of the protrusion 22 is processed into a hemispherical shape, so that the protrusion 22 can better clean the inside of the fluff of the mop and avoid scratching the mop at the same time.

[0069] Optionally, the scraping strip 24 and the protrusions 22 in the cleaning tank 12 can be integrally formed with the cleaning tank 12 as a whole. Optionally, the scraping strip 24 and the protrusions 22 can be arranged in the cleaning tank 12 by connection methods such as welding and gluing.

[0070] In some embodiments, the protrusion 22 is provided with a first water inlet hole.

[0071] In this way, when the mop passes through the combing part 18, the mop can be wetted and combed at the same time.

[0072] Specifically, the combing part 18 includes a plurality of protrusions 22. The protrusions 22 are provided with first water inlet holes, and the purified water can enter the cleaning tank 12 through the first water inlet holes. At the same time, when the mop is cleaned in the cleaning tank 12, it first passes through the combing part 18 and then through the scraping part 16. When the mop contacts the plurality of protrusions 22 of the combing part 18, water flows out of the first water inlet holes, which can moisten the mop. At the same time, the plurality of protrusions 22 comb the fluff of the mop. In this way, the cleaning efficiency can be improved.

[0073] Optionally, the first water inlet holes are opened at the tops of the plurality of protrusions 22, or the first water inlet holes are opened at the sides of the plurality of protrusions 22.

[0074] In one embodiment, the cleaning tank structure 10 is installed on the base station 100. A receiving groove 46 for accommodating the cleaning tank structure 10 is provided on the mounting base 44 of the base station 100. The water inlet pipe is arranged between the cleaning tank structure 10 and the receiving groove 46. The water inlet pipe is connected to an external purified water source and communicated with the first water inlet holes, so as to supply water to the first water inlet holes.

[0075] Furthermore, a booster pump is arranged on the water inlet pipe, which can increase the water outlet pressure of the first water inlet holes, so as to better moisten the mop.

[0076] Please refer to Figure 1 and Figure 2 , in some embodiments, the cleaning tank structure 10 includes a drainage channel 26 and a plurality of cleaning members 14. The plurality of cleaning members 14 and the bottom surface of the cleaning tank 12 enclose a diversion channel 28. The cleaning tank structure 10 includes a second water inlet hole 30 and a water outlet hole 32. The second water inlet hole 30 is communicated with the water outlet hole 32 through the diversion channel 28 and the drainage channel 26 in sequence.

[0077] In this way, the cleaning members 14 form the diversion channel 28, which can guide the sewage in the cleaning tank 12 to flow to the drainage channel 26 and flow out from the drainage channel 26, avoiding the accumulation of sewage in the cleaning tank 12.

[0078] Specifically, the cleaning tank structure 10 includes a plurality of cleaning members 14. The plurality of cleaning members 14 and the bottom surface of the cleaning tank 12 enclose a diversion channel 28. The diversion channel 28 is communicated with the drainage channel 26. The second water inlet hole 30 is arranged on one side of the diversion channel 28. The other side of the diversion channel 28 is communicated with the drainage channel 26, and the water outlet hole 32 is communicated with the drainage channel 26.

[0079] The purified water flows from the second water inlet hole 30 to the diversion channel 28. The mop is wetted by the purified water above the cleaning member 14. The mop rotates and directly contacts the cleaning member 14, so that the cleaning member 14 cleans the mop. The scraping part 16 scrapes off the dirt and sewage on the mop together. Most of the sewage flows to the diversion channel 28 and then is discharged from the water outlet hole 32 through the drainage channel 26. In this way, the sewage can be prevented from staying in the cleaning tank 12 to pollute the mop, and a better cleaning effect can be achieved.

[0080] Further, the scraping surface 20 of the scraping part 16 for cleaning the mop faces the direction opposite to the rotation direction of the mop. In this way, the scraping surface 20 can face the diversion channel 28. After the scraping strip 24 scrapes off the sewage on the mop, the sewage can directly flow into the diversion channel 28.

[0081] Please refer to Figure 2 , in one embodiment, the cleaning tank structure 10 further includes a water inlet channel 34. The water inlet channel 34 is communicated with the second water inlet hole 30 and the diversion channel 28. The water inlet channel 34 is used to divert the purified water flowing out of the second water inlet hole 30 into the cleaning tank 12. The structure of the water inlet channel 34 can be set according to the spatial layout of the base station 100 and the cleaning tank structure 10. In this way, the cleaning tank structure 10 can be applied to base stations 100 with different volumes and designs.

[0082] In one embodiment, the drainage channel 26 includes a drain pipe. One end of the drain pipe is communicated with the diversion channel 28, and the other end is communicated with the water outlet hole 32. The sewage enters the drain pipe from the diversion channel 28, and the drain pipe can collect the waste water and introduce it into the water outlet hole 32. In this way, the sewage can be better collected, and the situation that the sewage flows back to the cleaning tank 12 when a large amount of sewage accumulates in the drainage channel 26 can be avoided.

[0083] In some embodiments, the horizontal height h1 of the bottom surface of the drainage channel 26 on the side close to the diversion channel 28 is higher than the horizontal height h2 of the drainage channel 26 on the side close to the water outlet hole 32.

[0084] In this way, the drainage channel 26 has a good diversion effect.

[0085] Specifically, the drainage channel 26 gradually decreases along the direction from the diversion channel 28 to the water outlet hole 32, which is beneficial to the water flow approaching the water outlet hole 32 side under the action of gravity. In this way, the drainage channel 26 can have a diversion effect on the sewage and is conducive to guiding the sewage to the water outlet hole 32.

[0086] Further, the bottom surface of the drainage channel 26 is V-shaped or U-shaped, and the horizontal height of the middle position of the bottom surface of the drainage channel 26 is lower than the horizontal heights of the two side positions of the bottom surface of the drainage channel 26. In this way, the drainage channel 26 can have a better diversion effect on the sewage.

[0087] Please refer to Figure 3, in some embodiments, the bottom surface of the diversion channel 28 has a horizontal height h3 on the side close to the second water inlet 30 that is higher than the horizontal height h4 on the side of the diversion channel 28 close to the drainage channel 26.

[0088] In this way, the diversion channel 28 is inclined, which is conducive to guiding the water flow to the drainage channel 26 and the water outlet 32.

[0089] Specifically, after the purified water flows into the cleaning tank 12 from the second water inlet 30, most of the purified water is absorbed by the mop in the cleaning tank 12, and a small part of the purified water flows towards the drainage channel 26. During the process of cleaning the mop, the purified water becomes sewage after contacting the dirt on the mop, and is scraped off from the mop by the scraping part 16 and flows into the diversion channel 28.

[0090] Since the horizontal height h3 of the bottom surface of the diversion channel 28 on the side close to the second water inlet 30 is higher than the horizontal height h4 on the side of the diversion channel 28 close to the drainage channel 26, the sewage can spontaneously flow towards the drainage channel 26 by gravity, avoiding the sewage from accumulating in the cleaning tank 12 and polluting the mop.

[0091] Please refer to Figure 2 and Figure 3 , in some embodiments, the cleaning tank structure 10 includes a filter member 36. The filter member 36 surrounds the periphery of the water outlet 32, and the filter member 36 is provided with through holes 38 to communicate the water outlet 32 and the drainage channel 26.

[0092] In this way, the filter member 36 can filter solid dirt and prevent the water outlet 32 from being blocked.

[0093] Specifically, the filter member 36 surrounds the periphery of the water outlet 32, and can filter the sewage flowing towards the water outlet 32. The sewage may carry some hairs and solid dirt. The filter member 36 is provided with through holes 38 to communicate the water outlet 32 and the drainage channel 26. The sewage and small solid dirt can pass through the through holes 38 and be discharged from the water outlet 32. Some larger solid dirt can be intercepted by the filter member 36 outside the water outlet 32, preventing the larger solid dirt from accumulating and blocking the water outlet 32, causing a large amount of sewage to accumulate in the water outlet 32 and the drainage channel 26, and the sewage overflows from the cleaning tank 12 due to the inability to discharge the sewage.

[0094] Please refer to Figure 1 and Figure 2 , in some embodiments, the cleaning tank structure 10 includes a retaining strip 40. The retaining strip 40 surrounds at least part of the drainage channel 26 to isolate the cleaning tank 12 and at least part of the drainage channel 26.

[0095] In this way, the retaining strip 40 can isolate the sewage from the cleaning tank 12 and prevent the sewage from flowing back into the cleaning tank 12.

[0096] Specifically, the baffle 40 surrounds one side of the drainage channel 26 near the water outlet hole 32. When the sewage flows from the drainage channel 26 to the water outlet hole 32, the sewage can be buffered in the area surrounded by the baffle 40 and wait for filtration. In this way, the capacity of the drainage channel 26 to accommodate sewage can be improved, and it can prevent the sewage from flowing back into the cleaning tank 12 and overflowing from the cleaning tank 12.

[0097] Please refer to Figure 1 and Figure 2 , in some embodiments, the cleaning tank structure 10 includes a liquid level detection device 42. The liquid level detection device 42 is arranged on the baffle 40, and the liquid level detection device 42 is configured to send an alarm message when the water level in the drainage channel 26 reaches a preset height.

[0098] In this way, the sewage in the drainage channel 26 is detected. After the sewage accumulates to a certain extent, an alarm signal is triggered to prevent the sewage from overflowing.

[0099] Specifically, the baffle 40 surrounds one side of the drainage channel 26 near the water outlet hole 32. When the sewage flows from the drainage channel 26 to the water outlet hole 32, the sewage can be buffered in the area surrounded by the baffle 40. The liquid level detection device 42 is arranged on the baffle 40 and sends an alarm message when the water level in the drainage channel 26 reaches a preset height. Under the normal drainage capacity of the water outlet hole 32, the water level in the drainage channel 26 is lower than the preset height. Therefore, whether the water outlet hole 32 is blocked can be detected by the water level condition in the drainage channel 26. When the water level in the drainage channel 26 reaches the preset height, it can be considered that the water outlet hole 32 is blocked.

[0100] In one embodiment, when the liquid level detection device 42 sends an alarm message, the base station 100 stops supplying water to the cleaning tank 12. In this way, it can be avoided that when the water outlet hole 32 is blocked, the water overflows from the cleaning tank 12 to the base station 100 and the ground due to continuous water inflow in the cleaning tank 12.

[0101] In summary, when the mop is being cleaned in the cleaning tank 12, the mop is in direct contact with the scraping part 16 and the combing part 18, and the scraping part 16 and the combing part 18 clean the mop. A flow channel from the second water inlet hole 30 to the water outlet hole 32 is arranged in the cleaning tank structure 10, which can prevent the sewage from remaining in the cleaning tank 12 and polluting the mop, achieving a better cleaning effect. At the same time, liquid level detection is carried out at the water outlet. After the sewage accumulates to a certain extent, an alarm signal is triggered to prevent the sewage from overflowing.

[0102] Please refer to Figure 4 and Figure 5 , a base station 100 according to an embodiment of the present invention includes the cleaning tank structure 10 of any of the above embodiments.

[0103] For the above-mentioned base station 100, when the mopping cloth is being cleaned in the cleaning tank 12, the mopping cloth comes into contact with the scraping part 16 and the combing part 18. The mopping cloth directly contacts the scraping part 16 and the combing part 18. The combing part 18 combs the mopping cloth and enables the scraping part 16 to scrape the mopping cloth, thereby making the cleaning of the mopping cloth by the cleaning tank structure 10 more thorough and having a high cleaning efficiency.

[0104] Optionally, in one embodiment, the cleaning device may include the base station 100. In another embodiment, the cleaning device may include the base station 100 and a cleaning robot. The cleaning robot includes a double-rotary cleaning robot (with two mopping cloths) and a single-rotary cleaning robot (with a single mopping cloth). The rotation axis of the mopping cloth is perpendicular to the body of the cleaning robot.

[0105] In the figure, the base station 100 includes a housing 52. A receiving space 54 may be opened at a position near the bottom of the housing 52. The cleaning tank structure 10 may be installed in the receiving space 54, and the opening of the receiving space 54 may communicate with the external environment.

[0106] The base station 100 further includes a climbing plate 56. The climbing plate 56 may be connected to the edge of the receiving space 54 near the bottom of the base station 100. The cleaning robot may send the mopping cloth into the cleaning tank 12 through the climbing plate 56. It can be understood that the cleaning tank structure 10 may not only be provided in the base station 100, but also be provided on other devices for cleaning the components of other devices.

[0107] In the illustrated embodiment, the cleaning tank structure 10 may be used in cooperation with a double-rotary cleaning robot. After the cleaning robot finishes cleaning, it can return to the base station 100, place the mopping cloth in the cleaning tank 12 for cleaning, and at the same time, the base station 100 can also perform operations such as charging and dust collection on the cleaning robot. After the mopping cloth of the cleaning robot is cleaned or the cleaning robot is charged, the cleaning robot can leave the base station 100 to continue the cleaning work, or stay at the base station 100 until waiting for the next cleaning instruction.

[0108] Please refer to Figure 4 and Figure 5 , in some embodiments, the base station 100 includes a mounting base 44, and the cleaning tank structure 10 is detachably mounted on the mounting base 44.

[0109] In this way, the cleaning tank structure 10 is detachable, which is convenient for cleaning.

[0110] Specifically, a receiving groove 46 for accommodating the cleaning tank structure 10 is provided on the mounting base 44 of the base station 100, and the cleaning tank structure 10 is detachably clamped in the receiving groove 46. The user can take out the cleaning tank structure 10 from the base station 100 for cleaning, which is more convenient for cleaning the cleaning tank structure 10 and also avoids the accumulation of dirt in the cleaning tank structure 10 due to incomplete cleaning, thus affecting the cleaning effect of the mop.

[0111] In one embodiment, as Figure 4 shown, the cleaning tank structure 10 includes a handle 48, and the mounting base 44 includes an avoidance groove 50. When the cleaning tank structure 10 is clamped in the receiving groove 46, the handle 48 is located above the avoidance groove 50. 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 100 by applying an upward force by holding the handle 48. The avoidance groove 50 facilitates the user to hold the handle 48.
