[0061] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0062] like Figure 1-Figure 10 As shown, an embodiment of the present invention provides a cleaning device 100, comprising a cleaning mechanism 101; a base 102, which is disposed at the bottom end of the cleaning mechanism 101, and a mop 103 is connected to the bottom end of the base 102; a cleaning strip 104, which is movably connected to the base 102, and the cleaning strip 104 is in close contact with the mop 103 located on the base 102; and a driving mechanism 105, which is connected to the cleaning strip 104 to drive the cleaning strip 104 to reciprocate along the plane direction of the outer surface of the mop 103. In some embodiments, the cleaning mechanism 101 comprises a cleaning member 1011 capable of absorbing dust, and a water tank is further disposed in the cleaning member 1011, which is in communication with the mop 103, and provides clean water to the mop 103 when mopping the floor, so as to wet the mop 103 and clean the floor. By adopting the above scheme, a cleaning scraper 104 that can be closely attached to the mop 103 is arranged on the base 102. The driving mechanism 105 can scrape off the dirty water and adhered garbage on the mop 103 when driving the cleaning scraper 104 to move back and forth, thereby solving the problem of secondary contamination of the floor by the mop 103 when mopping the floor.

[0063] In some embodiments, the base 102 is provided with two guide rails 1021 arranged along the moving direction of the cleaning strip 104 at both ends of the cleaning strip 104, and the cleaning strip 104 includes a moving portion 1041 arranged at both ends thereof and capable of fitting in the guide rails 1021.

With the above solution, the cooperation of the guide rails 1021 and the moving portion 1041 makes the reciprocating movement of the cleaning strip 104 more stable, thereby better scraping away the dirty water and adhered garbage on the mop 103.

[0064] In some embodiments, the cleaning strip 104 includes a first strip portion 1042 connected to the two moving portions 1041, and a second strip portion 1043 movably connected between the two first strip portions 1042; and the first strip portion 1042 can perform telescopic movement along the length direction of the second strip portion 1043. In some embodiments, the guide rail 1021 is arranged along the outer wall of the base 102; the maximum extension of the two first strip portions 1042 relative to the second strip portion 1043 is at least greater than the maximum distance between the two oppositely arranged outer walls of the base 102; the maximum retraction of the two first strip portions 1042 relative to the second strip portion 1043 is at least greater than the minimum distance between the two oppositely arranged outer walls of the base 102. In some embodiments, a cavity is provided inside the second scraper portion 1043, so that the ends of the two first scraper portions 1042 that are close to each other can be fitted into the cavity of the second scraper portion 1043; thereby, the first scraper portion 1042 can be telescopically moved relative to the second scraper portion 1043; so that in the process in which the driving mechanism 105 drives the moving portion 1041 to reciprocate along the guide rail 1021, the first scraper portion 1042 can be telescopic relative to the second scraper portion 1043, thereby adapting to bases 102 of different shapes and the mop 103 disposed on the base 102, thereby completely scraping off the sewage and adhered garbage on the mop 103, solving the problem of secondary contamination of the floor by the mop 103 when mopping the floor, and making it cleaner and more hygienic. The above scheme is adopted to set a telescopic connection between the first scraper portion 1042 and the second scraper portion 1043, which can adapt to bases 102 of different shapes and has a wide range of applicable scenarios.

[0065] In some embodiments, the driving mechanism 105 includes a driving motor 1051, and a transmission gear 1052 is connected to the output end of the driving motor 1051. The transmission gear 1052 is meshed with a gear matching portion 1053, and the gear matching portion 1053 is formed on a transmission shaft 1054. The transmission shaft 1054 can rotate around its own central axis; and the two ends of the transmission shaft 1054 are respectively connected to the moving parts 1041 of the two cleaning strips 104; the forward and reverse rotations of the transmission shaft 1054 can drive the moving parts 1041 to reciprocate. In some embodiments, the two ends of the transmission shaft 1054 are arranged near one end of the two guide rails 1021. In some embodiments, the transmission shaft 1054 is near the end where the two guide rails 1021 are spaced apart by the maximum distance, and the length of the transmission shaft 1054 is at least greater than the maximum distance between the two guide rails 1021. In some embodiments, the driving motor 1051 is disposed on the dirt cleaning member 1011, the transmission shaft 1054 is relatively disposed below the driving motor 1051, and the base 102 is provided with a support portion 1022 for supporting the transmission shaft 1054, and the support portion 1022 is concave downward to form a recessed portion 1022a that can fit the transmission shaft 1054, so that the transmission shaft 1054 can rotate around its own central axis. With the above solution, through the cooperation of the transmission gear 1052 and the gear matching portion 1053, the forward or reverse rotation of the driving motor 1051 can drive the transmission shaft 1054 to rotate forward or reverse around its own central axis; thereby, the connecting portion 1041c can be driven to reciprocate along the guide rail 1021, so as to drive the reciprocating movement of the cleaning scraper 104, and completely scrape off the sewage and adhered garbage on the mop 103.

[0066] In some embodiments, both ends of the transmission shaft 1054 are connected to a connecting piece 1055, one end of the connecting piece 1055 is connected to the transmission shaft 1054, and the other end is connected to the moving part 1041.

In some embodiments, the moving part 1041 is provided with two mounting holes 1041d, which are respectively used to connect the moving part and the tension spring 106; the moving part is wound on the transmission shaft 1054, and the end of the guide rail 1021 away from the transmission shaft 1054 protrudes upward to form a mounting seat 1021a, and one end of the tension spring 106 is connected to the mounting seat 1021a. With the above scheme, when the driving motor 1051 drives the transmission shaft 1054 to move in a direction away from the moving part 1041, the moving part will be continuously wound on the transmission shaft 1054 to drive the moving part 1041 to move along the guide rail 1021 toward the direction close to the transmission shaft 1054, thereby driving the cleaning scraper 104 to move toward the side of the maximum spacing distance of the guide rail 1021. In this process, the first scraper part 1042 extends relative to the second scraper part 1043, so that the length of the cleaning scraper 104 in the length direction continues to increase, and the tension spring 106 is connected to the second scraper part 1043. 106 is continuously stretched during the process; when the driving motor 1051 drives the transmission shaft 1054 to move in the direction close to the moving part 1041, the moving part is continuously released, and during the process, the elastic force of the tension spring 106 gives the moving part 1041 a force to move in the direction away from the transmission shaft 1054; so as to drive the cleaning scraper 104 to move toward the side of the minimum spacing distance of the guide rail 1021. During the process, the first scraper part 1042 retracts relative to the second scraper part 1043, so that the length of the cleaning scraper 104 is continuously shortened.

In some embodiments, the distance between the first movable portion 1041a and the second movable portion 1041b is greater than the thickness of the base 102 with the mop 103; and, the first movable portion 1041a and the base 102 are arranged at an interval, and the second movable portion 1041b is close to the mop 103, so that the cleaning strip 104 is close to the mop 103, and can completely scrape off the dirty water and adhered garbage on the mop 103.
