[0042] The existing cleaning device mostly also has the function of spraying water mist to the surface to be cleaned for mopping. At this time, in order to avoid the solid garbage remaining on the roller brush from adhering to the wet surface to be cleaned when the cleaning device mops the surface to be cleaned, the existing cleaning device mostly adopts lifting the roller brush in the main machine to prevent the roller brush from contacting the surface to be cleaned when the cleaning device mops the surface to be cleaned, thereby avoiding the solid garbage remaining on the roller brush from adhering to the surface to be cleaned after mopping, and ensuring that the cleaning device can achieve good cleaning effect. However, by lifting the roller brush in the main machine to realize the avoidance of the roller brush, the cleaning groove in the main machine for accommodating the roller brush is still in open setting, and the roller brush is not well shielded, so that the solid garbage on the roller brush is easy to fall on the cleaned surface when the cleaning device shakes. In addition, the lifting range of the roller brush in the main machine is limited, and when the cleaning device passes through the surface with exposed structure such as clean carpet or blanket, the exposed fluff on the carpet or blanket is easy to contact the roller brush through the slot of the cleaning groove, so that the garbage adhered to the roller brush adheres to the clean surface, affecting the cleaning effect of the cleaning device and reducing the practicability of the cleaning device.

[0043] Reference Figures 1 to 12 In the embodiment of the present application, the cleaning device 100 comprises a main machine 10, a roller brush 30 and a shield 50. The main machine 10 has a working surface provided with a cleaning groove 11. The roller brush 30 is rotatably arranged in the cleaning groove 11 and partially exposed to the slot of the cleaning groove 11. The shield 50 is arranged on the main machine 10 and can open at least part of the slot of the cleaning groove 11 or close the slot of the cleaning groove 11.

[0044] It can be understood that the cleaning device 100 can be a sweeper, a mop-washing integrated machine or a cleaning robot, etc., at this time, the working surface of the main machine 10 can be the surface corresponding to the ground, table top or other surface to be cleaned when the cleaning device 100 is normally operating, the cleaning groove 11 can be formed by directly grooving on the working surface, or by inlaying a groove structure on the working surface, the rolling brush 30 can be driven to rotate in the cleaning groove 11, so that the part of the rolling brush 30 exposed to the slot of the cleaning groove 11 can directly rotate on the surface to be cleaned, and then the garbage on the surface to be cleaned can be swept, and the garbage swept by the rolling brush 30 can be sucked and collected by the suction device communicating with the working surface in the main machine 10, so as to achieve the purpose of cleaning the surface to be cleaned. At this time, the cover 50 can be installed in the cleaning groove 11 or on the outer circumferential side of the cleaning groove 11 in the main machine 10, and the cover 50 can be movably arranged in the main machine 10, or the cover 50 can be slidably arranged on the working surface of the main machine 10 and arranged close to the slot of the cleaning groove 11, so that the cover 50 can move towards or away from the slot of the cleaning groove 11, and the cover 50 can open at least part of the slot of the cleaning groove 11 or completely close the slot of the cleaning groove 11. Thus, when the cleaning device 100 cleans the surface to be cleaned by using the rolling brush 30, the cover 50 can be accommodated in the main machine 10 to open the slot of the cleaning groove 11, so that the rolling brush 30 can rotate on the surface to be cleaned for cleaning; when the cleaning device 100 needs to wet-wash or mop-wash the surface to be cleaned, the cover 50 can be moved to the slot of the cleaning groove 11, so that the cover 50 closes the slot of the cleaning groove 11, so that the cover 50 and the cleaning groove 11 can form a space with a certain airtightness, and the rolling brush 30 can be accommodated in the space formed by the cover 50 and the cleaning groove 11, so that the rolling brush 30 can be isolated from the surface to be cleaned when the cleaning device 100 wet-washes or mop-washes the surface to be cleaned, so as to effectively prevent dust or garbage attached to the rolling brush 30 from falling and adhering to the surface to be cleaned, so that the cleaning device 100 can better mop-wash the surface to be cleaned, and the good cleaning effect of the cleaning device 100 is ensured.

[0045] By installing the cover 50 close to the inner or outer wall of the cleaning tank 11, the area occupied by the cover 50 within the main unit 10 can be effectively reduced. Compared to raising the roller brush 30 within the main unit 10 to avoid the surface to be cleaned, by using the cover 50 to shield the roller brush 30 during mopping, it is not necessary to provide a large space within the main unit 10 to accommodate the roller brush 30, allowing the roller brush 30 to be completely contained within the main unit 10 during mopping, thus effectively reducing the area occupied by the roller brush 30 within the main unit 10. At the same time, the cover 50 can completely enclose the roller brush 30 during mopping, effectively preventing debris attached to the roller brush 30 from falling onto the surface to be cleaned, thereby ensuring a good cleaning effect of the cleaning device 100 and improving the practicality and structural reliability of the cleaning device 100.

[0046] Secondly, when the cleaning device 100 is also equipped with mopping tools such as a mop for cleaning the surface, a cover 50 can be installed in the space within the main unit 10 where the mopping tools are housed. This allows the cover 50 to conceal the mopping tools when the cleaning device 100 uses the roller brush 30 for cleaning. This helps prevent the mopping tools with residual dirt from contacting and contaminating the surface, thus affecting the cleaning effect of the cleaning device 100. It also prevents the clean mopping tools from becoming contaminated during the cleaning or placement process, ensuring a better cleaning effect. Furthermore, the cover 50 provides a degree of airtightness, preventing the spread of odors from the dirty mopping tools after cleaning. It also helps to shield noise during the cleaning and drying process, achieving a certain noise reduction effect and further improving the structural reliability and practicality of the cleaning device 100.

[0047] The technical scheme of the present application sets the shield 50 in the main machine 10, and the shield 50 can move on the main machine 10, so that the shield 50 can open at least part of the slot of the cleaning groove 11 or close the slot of the cleaning groove 11, and then when the cleaning device 100 cleans the surface to be cleaned, the shield 50 can open the slot of the cleaning groove 11, so that the roller brush 30 is exposed to the slot of the cleaning groove 11 to sweep the garbage on the surface to be cleaned to realize the cleaning of the surface to be cleaned. When the cleaning device 100 needs to mop the surface to be cleaned, the shield 50 can close the slot of the cleaning groove 11, so that the shield 50 surrounds the roller brush 30 to isolate the roller brush 30 from the surface to be cleaned, which can prevent the garbage attached to the roller brush 30 from falling and being adsorbed on the surface to be cleaned after mopping, thereby improving the cleaning effect of the cleaning device 100 and improving the structural reliability of the cleaning device 100. Compared with the method of lifting the roller brush 30 in the cleaning groove 11 to avoid the surface to be cleaned, the use of the shield 50 to shield the roller brush 30 can also reduce the occupied space of the roller brush 30 in the main machine 10, facilitate the miniaturization design of the cleaning device 100, and further improve the practicability of the cleaning device 100.

[0048] In an embodiment of the present application, when the shield 50 opens at least part of the slot of the cleaning groove 11, the shield 50 is located between the roller brush 30 and the inner wall of the cleaning groove 11, and the rotation center axis of the shield 50 does not coincide with the rotation center axis of the roller brush 30. When the shield 50 closes the slot of the cleaning groove 11, the roller brush 30 abuts against the side of the shield 50 facing the roller brush 30.

[0049] After the cleaning device 100 completes the cleaning of the surface to be cleaned, the shield 50 can be rotated to close the slot of the cleaning groove 11, and the roller brush 30 can abut against the side of the shield 50 facing the roller brush 30. At this time, the roller brush 30 can be rotated on the shield 50, so that the roller brush 30 and the shield 50 can be scraped with each other, thereby scraping off the garbage attached to the roller brush 30 and the side of the shield 50 facing the roller brush 30, so that the garbage scraped off can be removed by the dirt suction device in the main machine 10, thereby realizing the self-cleaning of the roller brush 30 and the shield 50, and the user does not need to disassemble the roller brush 30 and the shield 50 to manually clean the roller brush 30, the shield 50 and the inner wall of the cleaning groove 11, thereby improving the operation experience of the cleaning device 100, making the user's use more comfortable, and further improving the practicability and structural reliability of the cleaning device 100.

[0050] The rotation center axis of the cover 50 is not overlapped with the rotation center axis of the roller brush 30, that is, the rotation center of the cover 50 is arranged eccentrically with the rotation center of the roller brush 30, so that when the cover 50 is turned to open the slot of the cleaning tank 11, the side of the cover 50 facing the roller brush 30 has a certain distance from the roller brush 30, so that the cover 50 can avoid the roller brush 30 to rotate and sweep the garbage on the surface to be cleaned, and the normal operation of the cleaning device 100 is ensured; and when the cover 50 is turned to close the slot of the cleaning tank 11, the roller brush 30 can better abut against the side of the cover 50 facing the roller brush 30, so that the self-cleaning function of the roller brush 30 and the cover 50 can be well realized, and the overall structural stability and reliability of the cleaning device 100 are further improved.

[0051] Further, the rotation center axis of the cover 50 is located above the rotation center axis of the roller brush 30. In this embodiment, by arranging the rotation center axis of the cover 50 above the rotation center axis of the roller brush 30, the cross section of the rotation track of the cover 50 and the cross section of the rotation track of the roller brush 30 are in a certain overlapping eccentric circular shape, which is beneficial to better enable the cover 50 to be located between the inner wall of the slot of the cleaning tank 11 and the roller brush 30 when the cover 50 is turned to open the slot of the cleaning tank 11, and to enable the cover 50 to have a certain distance from the roller brush 30 to avoid the rotation of the roller brush 30; at the same time, the cover 50 can better abut against the roller brush 30 when the cover 50 is turned to close the slot of the cleaning tank 11, so that the cleaning device 100 can better realize a certain self-cleaning function, and the use requirements of the user are met.

[0052] Further, the side of the cover 50 facing the roller brush 30 is provided with a scraping member 515, which abuts against the roller brush 30 when the cover 50 closes the slot of the cleaning tank 11. In this embodiment, by arranging the scraping member 515 on the side of the cover 50 facing the roller brush 30, the roller brush 30 can directly abut against the scraping member 515 when the cover 50 is turned to close the slot of the cleaning tank 11, which is beneficial to increase the contact area of the cover 50 and the roller brush 30 by using the scraping member 515, so that the scraping member 515 can better scrape the garbage attached to the roller brush 30, realize better self-cleaning effect, and further reduce the cleaning frequency of the user on the roller brush 30 and the cover 50, so that the user has a better use experience, and the practicality and structural reliability of the cleaning device 100 are further improved. The scraping member 515 can be a plurality of scraping grooves recessed on the cover 50, so that the bristles on the roller brush 30 can be shaken by the scraping grooves during rotation to shake off the dust or garbage debris attached to the roller brush 30; or the scraping member 515 can be a block structure or a columnar structure embedded on the cleaning cover, so that the scraping member 515 can directly scrape off the garbage attached to the roller brush 30 during the rotation of the roller brush 30, and realize the self-cleaning function of the cleaning device 100.

[0053] Further, the scraping member 515 comprises a plurality of protruding contacts which are arranged at intervals on the side of the cover 50 facing the roller brush 30. In the embodiment, the scraping member 515 can be formed by inlaying a plurality of protruding contacts on the side of the cover 50 facing the roller brush 30, so that the plurality of protruding contacts arranged at intervals can further increase the frequency of mutual scraping of the cover and the roller brush 30, thereby facilitating better mutual cleaning of the cover 50 and the roller brush 30, achieving better self-cleaning effect, so that the user does not need to regularly clean the cover 50 and the roller brush 30 of the cleaning device 100, further improving the practicability and structural reliability of the cleaning device 100. The protruding contacts can also be formed by an integrated process with the cover 50, which facilitates more stable and reliable overall structure of the cover 50, improves the structural strength of the cover 50, and further makes the direct abutment and scraping of the cover 50 and the roller brush 30 more stable and reliable, further improving the self-cleaning effect of the cleaning device 100.

[0054] With reference to Figures 2 to 9 In an embodiment of the present application, the cover 50 is rotatably arranged in the cleaning tank 11, and the cover 50 opens at least part of the slot of the cleaning tank 11 or closes the slot of the cleaning tank 11 during rotation.

[0055] In the embodiment, the cover 50 can be arranged in the cleaning tank 11, and the cover 50 can open at least part of the slot of the cleaning tank 11 or completely close the slot of the cleaning tank 11 by rotating the cover 50 in the cleaning tank 11. By rotatably arranging the cover 50 in the cleaning tank 11, the cover 50 can be well accommodated on the inner wall of the slot of the cleaning tank 11 when opening the slot of the cleaning tank 11, which facilitates better reduction of the occupied area of the cover 50 on the main machine 10. Further, the cross-sectional shape of the cleaning tank 11 can be circular, and at this time, the cross-sectional shape of the cover 50 can also be circular, so that the cover 50 can better fit the inner wall of the slot of the cleaning tank 11, further reducing the occupied area of the cover 50 on the main machine 10, and also enabling the cover 50 to better surround the roller brush 30 when closing the slot of the cleaning tank 11, further avoiding the garbage attached to the roller brush 30 from falling on the surface to be cleaned, thereby affecting the cleaning effect of the cleaning device 100.

[0056] Secondly, by arranging the cover 50 in the cleaning tank 11, the cover 50 can be located between the inner wall of the slot of the cleaning tank 11 and the roller brush 30 when opening the slot of the cleaning tank 11, and thus the garbage not sucked by the roller brush 30 can be attached to the cover 50 when the roller brush 30 sweeps the surface to be cleaned, thereby avoiding the garbage from being attached to the inner wall of the slot of the cleaning tank 11, so that the user can directly clean by disassembling the cover 50 and the roller brush 30 in daily maintenance, facilitating daily cleaning and maintenance of the user, and making the user have a better use experience.

[0057] Further, with reference toFigure 2 、 Figure 4 、 Figure 6 and Figure 7 In one embodiment of the present application, the main body 10 is provided with a collecting cavity 13, the cleaning tank 11 is provided with a suction opening 111 communicating with the collecting cavity 13, and the cover 50 opens at least part of the suction opening 111 or closes the suction opening 111 during rotation.

[0058] It can be understood that in daily use, the dirt collecting cavity 13 in the host 10 can suck up the garbage swept up by the roller brush 30 through the garbage suction port 111 and temporarily store and collect the garbage, and a base station can be provided in the cleaning device to park and charge the cleaning device 100 and recover the garbage collected by the cleaning device 100 and the like, so that the cleaning device 100 can discharge the garbage temporarily stored in the dirt collecting cavity 13 in the base station, so that the cleaning device 100 can better continuously operate. The host 10 and the base station can be provided with a fan or a pump or the like negative pressure suction device, so that the cleaning device 100 can form a suction air flow at the dirt collecting cavity 13 and the garbage suction port 111 by using the negative pressure suction device during cleaning, so as to collect the garbage on the surface to be cleaned through the garbage suction port into the dirt collecting cavity 13 to realize the recovery and temporary storage of the garbage. By arranging the garbage suction port 111 on the cleaning tank 11, the roller brush 30 rotating in the cleaning tank 11 can better drive the swept garbage to the garbage suction port 111 to be sucked by the dirt collecting cavity 13, so as to ensure that the cleaning device 100 has good cleaning effect. At this time, the cover 50 rotating in the cleaning tank 11 can pass through the garbage suction port 111 during rotation, so that the cover 50 can shield the garbage suction port 111 during rotation, and then the cover 50 can open at least part of the garbage suction port 111 or close the garbage suction port 111, so that when the cleaning device 100 sweeps the surface to be cleaned, the cover 50 can be adjusted by rotating the cover 50 to shield part of the garbage suction port 111 to adjust the air inlet size of the garbage suction port 111, and under the action of the same wind force, the smaller the air inlet size of the garbage suction port 111, the greater the air flow pressure passing through the garbage suction port 111, so that reducing the size of the garbage suction port 111 by using the cover 50 can form stronger garbage suction force, so that the garbage swept up by the roller brush 30 can be better sucked into the dirt collecting cavity 13 through the garbage suction port 111, to achieve better cleaning effect. At the same time, when the cleaning device 100 cleans the surface to be cleaned, the flow direction of the garbage suction air flow is in turn through the tank opening of the cleaning tank 11, the garbage suction port 111 and the dirt collecting cavity 13, and at this time, the cover 50 can be opened at least part of the tank opening of the cleaning tank 11 by rotating the cover 50, so as to adjust the size of the tank opening of the cleaning tank 11 by using the cover 50, and then the air inlet size of the tank opening of the cleaning tank 11 can be adjusted, so as to adjust the flow rate and pressure of the garbage suction air flow, which is conducive to improving the negative pressure adsorption effect of the cleaning device 100 during cleaning, and better sucking the garbage on the surface to be cleaned. Among them, the user can adjust the rotation angle of the cover 50 according to the actual use requirement, so that the size of the garbage suction port 111 or the tank opening of the cleaning tank 11 can better suck the garbage with larger volume while ensuring that the dirt collecting cavity 13 has better garbage suction force, so that the cleaning device 100 can better meet the use requirement of the user, and further improve the cleaning effect of the cleaning device 100.And, the size of the air inlet of the suction port or the slot of the cleaning tank 11 is adjusted by the shield 50 to adjust the negative pressure adsorption of the cleaning device 100. Compared with adjusting the power of the negative pressure adsorption device on the main machine 10 to adjust the negative pressure adsorption of the cleaning device, the method is beneficial to better reduce the components of the cleaning device 100, effectively simplify the overall structure of the cleaning device 100, facilitate the miniaturization design of the cleaning device 100, and further improve the structural reliability and practicality of the cleaning device 100.

[0059] Secondly, when the base station recycles the garbage temporarily stored in the garbage collecting cavity 13, the negative pressure suction device in the base station can form a suction air flow in the garbage collecting cavity, and the negative pressure suction device on the main machine 10 can form a sewage air flow in the garbage collecting cavity. Under the synergistic effect of the two air flows, the garbage in the garbage collecting cavity 13 can be driven by the air flow to pass through the sewage port on the main machine 10 and be discharged into the base station for recycling. At this time, by completely closing the sewage port 111 or the slot of the cleaning tank 11 by the shield 50, the air flow can be prevented from overflowing through the sewage port 111 or the slot of the cleaning tank 11 when the cleaning device 100 discharges sewage, so that the cleaning device 100 and the main machine 10 can be better sealed to form a one-way sewage air flow. In this way, the garbage in the garbage collecting cavity 13 can be better discharged from the sewage port along the air flow, which is beneficial to better improve the air flow velocity and pressure in the garbage collecting cavity 13 during sewage discharge, so that the garbage temporarily stored in the garbage collecting cavity 13 can be more completely recycled into the base station. At the same time, the garbage in the garbage collecting cavity 13 is prevented from leaking into the cleaning tank 11 through the sewage port 111 during sewage discharge, the cleanliness of the cleaning device 100 is ensured, and the practicality and structural reliability of the cleaning device 100 are further improved.

[0060] Further, with reference to Figure 2 、 Figures 4 to 7 In an embodiment of the present application, the shield 50 is provided with an avoiding port 511 which is communicated with the sewage port 111 when the shield 50 opens the slot of the cleaning tank 11.

[0061] In the embodiment, in order to make the shield 50 can more fully shield the roller brush 30 when the cleaning device 100 performs mopping on the surface to be cleaned, the shield 50 can be arranged corresponding to the inner wall of the cleaning tank 11, so that the shield 50 can have a larger overall size, and then the shield 50 can better completely close the slot opening of the cleaning tank 11, so that the roller brush 30 is completely surrounded by the shield 50 and the cleaning tank 11, which is beneficial to better isolate the roller brush 30 from the surface to be cleaned when the cleaning device 100 performs mopping. At this time, by arranging the avoiding opening 511 on the shield 50, the avoiding opening 511 can correspond to the dirt suction opening 111 in the cleaning tank 11 when the shield 50 completely opens the slot opening of the cleaning tank 11, and then the cleaning device 100 can better suck the garbage into the dirt collecting cavity 13 when cleaning, and the cleaning effect of the cleaning device 100 is guaranteed. During the process of rotating the shield 50 to close the slot opening of the cleaning tank 11, the avoiding opening 511 can gradually move with the rotation of the shield 50, and at this time, the part of the avoiding opening 511 communicated with the dirt suction opening 111 gradually decreases, and then the purpose of adjusting the air inlet size of the dirt suction opening 111 by rotating the shield 50 is achieved, so that the cleaning device 100 can better recycle the garbage swept by the roller brush 30 into the dirt collecting cavity 13, and the practicability and structural reliability of the cleaning device 100 are further improved.

[0062] Further, with reference to Figure 2 、 Figures 4 to 7 In an embodiment of the present application, the shield 50 is provided with a first sealing structure around the periphery of the avoiding opening 511, and the first sealing structure abuts against the inner wall of the cleaning tank 11. Alternatively, the inner wall of the cleaning tank 11 is provided with a second sealing structure 113 around the periphery of the dirt suction opening 111, and the second sealing structure 113 abuts against the side of the shield 50 facing the inner wall of the cleaning tank 11.

[0063] In the embodiment, by arranging the first sealing structure on the shield 50, the first sealing structure is arranged around the periphery of the avoiding opening 511, and the first sealing structure abuts against the inner wall of the cleaning tank 11, so that the gap between the shield 50 and the inner wall of the cleaning tank 11 can be sealed by the first sealing structure, so that the dirt suction airflow in the dirt collecting cavity 13 can flow better at the dirt suction opening 111 and the avoiding opening 511, and the airflow entering the gap between the shield 50 and the cleaning tank 11 is reduced, which is beneficial to better improve the flow rate and pressure of the dirt suction airflow, and at the same time, the garbage is prevented from being accumulated in the gap between the shield 50 and the cleaning tank 11 along the dirt suction airflow, and the practicability and structural reliability of the cleaning device 100 are further improved.

[0064] Similarly, by arranging the second sealing structure 113 on the inner wall of the cleaning tank 11, the second sealing structure 113 is arranged around the periphery of the exhaust port 111, and the second sealing structure 113 is arranged on the side of the cover 50 facing the inner wall of the cleaning tank 11. The second sealing structure 113 can block the gap between the cover 50 and the inner wall of the cleaning tank 11, so that the exhaust gas flow in the dirt collecting chamber 13 can flow better at the exhaust port 111 and the escape port 511, reducing the flow of gas into the gap between the cover 50 and the cleaning tank 11. It is beneficial to better improve the flow rate and pressure of the exhaust gas flow, while avoiding the accumulation of garbage along the exhaust gas flow in the gap between the cover 50 and the cleaning tank 11, further improving the practicability and structural reliability of the cleaning device 100.

[0065] The first sealing structure and the second sealing structure 113 can be made of rubber, silicone and other sealing gels with certain elasticity, so that the first sealing structure and the second sealing structure 113 can better abut on the inner wall of the cleaning tank 11 or the cover 50 to achieve better sealing effect. When the cover 50 rotates in the cleaning tank 11, the first sealing structure or the second sealing structure 113 can be compressed to avoid the rotation of the cover 50, ensuring the normal operation of the cleaning device 100, and further improving the structural stability and reliability of the cleaning device 100.

[0066] Referring to Figures 2 to 7 In an embodiment of the present application, the cover 50 is provided with a sealing member 513 connected to the side of the cover 50 facing the inner wall of the cleaning tank 11 and abutting the inner wall of the cleaning tank 11 when the cover 50 rotates in the cleaning tank 11.

[0067] In this embodiment, the sealing member 513 arranged on the cover 50 can effectively block the gap between the cover 50 and the inner wall of the cleaning tank 11, which is beneficial to prevent the garbage swept up by the roller brush 30 from being blocked between the cover 50 and the inner wall of the cleaning tank 11 when the roller brush 30 cleans the surface to be cleaned. The garbage can better concentrate on the exhaust port 111 and be sucked into the dirt collecting chamber 13, so that the user does not need to disassemble the cover 50 to clean the outer wall of the cover 50 and the inner wall of the cleaning tank 11 after the cleaning device 100 operates for a period of time, which improves the user's experience.

[0068] Meanwhile, the sealing piece 513 can abut against the inner wall of the cleaning tank 11 when the cover 50 rotates in the cleaning tank 11, and the sealing piece 513 can tightly abut against and scrape the inner wall of the cleaning tank 11, so that the cover 50 can clean the inner wall of the cleaning tank 11 when rotating, and the self-cleaning function of the cleaning tank 11 is achieved, which is beneficial to better reduce the daily maintenance and cleaning burden of the user, better the use experience of the user, and further improve the practicality of the cleaning device 100.

[0069] The sealing piece 513 can be made of a sealing gel material such as silica gel or rubber, and can be arranged along the length direction of the cover 50, so that the sealing piece 513 can be arranged in multiple strip-shaped sealing pieces arranged at intervals on the outer wall of the cover 50 or a sealing block arranged between the cover 50 and the cleaning tank 11, so that the sealing piece 513 can better block the gap between the cover 50 and the cleaning tank 11, and further reduce the accumulation of garbage between the cover 50 and the inner wall of the cleaning tank 11.

[0070] Referring to Figure 5 , Figure 8 , Figure 9 , Figure 11a and Figure 11b , in an embodiment of the present application, the side wall of the cleaning tank 11 is provided with a limiting hole 115, and the opposite sides of the cover 50 are respectively provided with a fixing cylinder 517, the fixing cylinder 517 is rotatably inserted into the limiting hole 115, and the two ends of the roller brush 30 are respectively arranged in the fixing cylinders 517 on the opposite sides of the cover 50.

At this time, the hollow cylinder-shaped fixing cylinder 517 structure is used as the rotation center of the cover 50, and the two ends of the roller brush 30 are arranged in the fixing cylinders 517 on the opposite sides of the cover 50, which effectively avoids the mutual interference of the roller brush 30 and the cover 50 when they rotate in the cleaning tank 11, so that the roller brush 30 and the cover 50 can both rotate in the cleaning tank 11, the normal cleaning of the roller brush 30 is ensured, and the cover 50 can be stably rotated to close the slot of the cleaning tank 11 to shield the roller brush 30, which further improves the structural stability and reliability of the cleaning device 100, and ensures the normal operation of the cleaning device 100.

[0072] The limiting hole 115 can be a through hole penetrating the groove side wall of the cleaning groove 11, and in this case, the two ends of the rolling brush 30 can be connected to the driving device arranged in the main machine 10 through the fixing cylinder 517 and the limiting hole 115, so as to realize the rotation of the rolling brush 30 in the cleaning groove 11. Alternatively, the limiting hole 115 can be a blind hole structure, and the rolling brush 30 can be inserted on the blind plate at one end of the limiting hole 115 through the fixing hole, and the rolling brush 30 is driven to rotate in the cleaning groove 11 by the driving device.

[0073] Further, with reference to Figure 8 、 Figure 9 、 Figure 11a 、 Figure 11b In an embodiment of the present application, the main machine 10 is provided with a first driving source 15, the first driving source 15 is provided with a rotating rod 151, one end of the rotating rod 151 away from the first driving source 15 is arranged in the limiting hole 115, one end of the rolling brush 30 is rotatably inserted into the groove side wall of the cleaning groove 11 through the fixing cylinder 517 on one side of the cover 50, the other end of the rolling brush 30 is connected with the rotating rod 151 through the fixing cylinder 517 on the other side of the cover 50, and the first driving source 15 drives the rotating rod 151 to drive the rolling brush 30 to rotate.

[0074] In the embodiment, one end of the rolling brush 30 can be rotatably inserted into one groove side wall of the cleaning groove 11 through the fixing cylinder 517 on one side of the cover 50, and in this case, the first driving source 15 is arranged in the main machine 10, and the rotating rod 151 connected with the first driving source 15 is arranged in the other groove side wall of the cleaning groove 11 and connected with the other end of the rolling brush 30, so that the rolling brush 30 can be well limited in the cleaning groove 11, and the rotating rod 151 can be well driven by the first driving source 15 to drive the rolling brush 30 to make a circular motion in the cleaning groove 11. Since the hollow cylinder structure of the fixing cylinder 517 is used, the two ends of the rolling brush 30 can be stably and independently rotated by being arranged in the fixing cylinder 517, so that the cover 50 and the rolling brush 30 can be independently rotated, the mutual interference between the cover 50 and the rolling brush 30 is avoided, and the overall structural stability and reliability of the cleaning device 100 are further improved.

[0075] Further, with reference to Figures 8 to 10In one embodiment of the present application, the fixed cylinder 517 is provided with first clamping teeth 5171 towards the inner wall of the rolling brush 30, and the first driving source 15 is further provided with a ratchet wheel 153, which is arranged in the fixed cylinder 517.

The second clamping teeth 1535 are swingably connected to the outer circumferential side of the rotating wheel 1531 and connected to the elastic member 1533. When the rotating wheel 1531 rotates in the first rotating direction, the second clamping teeth 1535 clamp the first clamping teeth 5171. When the rotating wheel 1531 rotates in the second rotating direction, the second clamping teeth 1535 compress the elastic member 1533 to avoid the first clamping teeth 5171.

[0076] In the embodiment, the first driving source 15 can drive the cover 50 through the gear connection between the ratchet wheel 153 and the fixed cylinder 517 by setting the ratchet wheel 153 on the rotating rod 151 and setting the ratchet wheel 153 in the fixed cylinder 517. When the cleaning device 100 needs to clean the surface to be cleaned, the first driving source 15 can first drive the rotating rod 151 to rotate in the first rotation direction, at this time, the second clamping tooth 1535 on the ratchet wheel 153 can be clamped and fixed with the first clamping tooth 5171, so that the first driving source 15 can drive the ratchet wheel 153 to rotate through the rotating rod 151, and make the ratchet wheel 153 drive the cover 50 to rotate through the second clamping tooth 1535, and then the first driving source 15 can drive the cover 50 to rotate to open the slot of the cleaning groove 11, so that the roller brush 30 can be exposed in the slot of the cleaning groove 11, and then the first driving source 15 drives the rotating rod 151 to rotate in the second rotation direction, at this time, the second clamping tooth 1535 can be clamped and fixed with the first clamping tooth 5171 in the rotating process of the ratchet wheel 153, and the second clamping tooth 1535 can be pushed and compressed by the first clamping tooth 5171 to avoid the first clamping tooth 5171 in the rotating process, and then the cover 50 can be kept in the cleaning groove 11 without moving, so that the first driving source 15 can drive the roller brush 30 to rotate through the rotating rod 151, and the cleaning function of the cleaning device 100 can be realized. When the cleaning device 100 needs to mop and wash the surface to be cleaned, the first driving source 15 can drive the rotating rod 151 to rotate in the first rotation direction again, so that the cover 50 can close the slot of the cleaning groove 11 under the driving of the ratchet wheel 153, and the cover 50 can isolate the roller brush 30 from the surface to be cleaned to ensure the mopping effect of the cleaning device 100. Under the action of the ratchet wheel 153, the cleaning device 100 can drive the cover 50 and the roller brush 30 by using a single driving device, which effectively reduces the driving device in the cleaning device 100, facilitates the reduction of the component setting of the cleaning device 100, is conducive to better realizing the miniaturization design of the cleaning device 100, reduces the production cost of the cleaning device 100, and further improves the practicability and structural reliability of the cleaning device 100.
