[0040] The present invention provides a cleaning robot 1 .

[0041] In the embodiment of the present invention, Figures 1 to 5 As shown, the cleaning robot 1 comprises:

[0042] A base station 10, wherein a receiving cavity 11 having an opening is provided on one side of the base station 10, a cleaning groove 111 is provided on a cavity wall of the receiving cavity 11 close to the bottom of the base station 10, and a limiting portion 13 is provided on the groove wall of the cleaning groove 111;

[0043] The main machine 20 is located in the accommodating chamber 11 and at one side of the cleaning tank 111. The main machine 20 includes a body 21 and a mopping mechanism 23. The mopping mechanism 23 includes a driving component 231 and a mopping cloth 233. One end of the driving component 231 is connected to the body 21, and the other end is connected to the mopping cloth 233 to drive the mopping cloth 233 to move closer to or away from the body 21.

[0044] The cleaning mechanism 30 includes a cleaning mesh cover 31 and a locking assembly 33. The locking assembly 33 includes a locking member 331 and an unlocking device 332. The cleaning mesh cover 31 is disposed in the cleaning tank 111.

The unlocking device 332 is disposed at the bottom of the cleaning tank 111 and is disposed corresponding to the cleaning mesh cover 31.

[0045] The host 20 has a cleaning state and a dehydration state. In the cleaning state, the driving component 231 drives the mop 233 to extend into the cleaning tank 111 to press the cleaning net cover 31 and push the locking piece 331 to lock with the limit part 13; in the dehydration state, the driving component 231 drives the mop 233 to extend out of the cleaning tank 111, the locking piece 331 and the limit part 13 are unlocked, and the unlocking device 332 pushes the cleaning mechanism 30 to extend out of the cleaning tank 111.

[0046] In this embodiment, a receiving chamber 11 with an opening is provided on one side of the base station 10, and a cleaning groove 111 is provided on a wall of the receiving chamber 11 near the bottom of the base station 10. The host 20 can enter and exit the opening of the receiving chamber 11. When entering the receiving chamber 11, it is located above the cleaning groove 111. The driving component 231 of the host 20 can drive the mop 233 to extend into the cleaning groove 111 to clean the mop 233, so that the cleaning robot 1 automatically cleans the mop 233. After cleaning the mop 233, the driving component 231 can drive the mop 233 to extend from the cleaning groove 111 and perform processes such as dehydration or drying.

[0047] The host 20 includes a body 21 and a mopping mechanism 23, and the mopping mechanism 23 includes a driving component 231 and a mop 233. One end of the driving component 231 is connected to the body 21, and the other end is driven to connect to the mop 233, so that the driving component 231 can drive the mop 233 to move or rotate, that is, it can drive the mop 233 to move in a direction close to or away from the body 21, and drive the mop 233 to rotate, so as to achieve the effect of the mop 233 extending and rotating relative to the body 21, and thus achieve the effect of the mop 233 entering and exiting the cleaning tank 111 and rotating to clean or rotate to mop. The driving component 231 can be a driving cooperation of the motor 2311 and the screw rod, the roller, the motor 2311 and the cylinder, the connecting rod, or the motor 2311 and the rack, the gear, which is not limited here.

[0048] The cleaning mechanism 30 includes a cleaning mesh cover 31 and a locking assembly 33. The cleaning mesh cover 31 may be provided with cleaning holes formed by a plurality of meshes, or may be cleaning holes formed by a plurality of racks, or may be mesh cleaning holes, which are not limited here. The locking assembly 33 includes a locking member 331 and an unlocking device 332, and the locking member 331 is movably connected to one end of the cleaning mesh cover 31 close to the cleaning tank 111 to lock or disengage with the limiting portion 13. The limiting portion 13 is arranged on the tank wall of the cleaning tank 111. It can be understood that the limiting portion 13 can be arranged on the side wall of the cleaning tank 111, that is, the limiting portion 13 can be a limiting hole, a limiting groove, etc., and the limiting portion 13 can also be arranged at the bottom of the cleaning tank 111, that is, the limiting portion 13 can be a limiting buckle, a limiting strip, etc. Further, the limiting portion 13 can also be a limiting protrusion, and a limiting hole, a limiting groove, a limiting buckle, etc. are arranged on the limiting protrusion. In this embodiment, the locking member 331 follows the cleaning net cover 31 to the position of the limiting portion 13 of the cleaning tank 111, and can be connected and locked with the limiting portion 13. The locking method can be plug-in limiting cooperation, buckle limiting cooperation, latch limiting cooperation, extrusion and holding limiting cooperation, etc. Further, the locking member 331 and the limiting portion 13 can also be set as magnetic suction members, and the locking member 331 and the limiting portion 13 can be magnetically connected by magnetism to achieve the effect of connecting and fixing the two, and the locking member 331 can also be locked and connected with the limiting portion 13. In this embodiment, the cleaning net cover 31 and the locking assembly 33 drive the mop 233 to press into the cleaning tank 111 through the driving assembly 231. The locking member 331 reaches the position of the limiting portion 13 and can be locked and connected with the limiting portion 13, thereby fixing the position of the locking member 331 relative to the limiting portion 13, and thereby fixing the position of the cleaning net cover 31 in the cleaning tank 111. Since the mop 233 is always in contact with the cleaning net cover 31, the rotation of the mop 233 can make the mop 233 rotate relative to the cleaning net cover 31. The contact between the mop 233 and the cleaning net cover 31 and the arrangement of the cleaning member on the cleaning net cover 31 can increase the friction between the mop 233 and the cleaning net cover 31, thereby facilitating the falling of dirt attached to the mop 233 and improving the cleaning effect of the mop 233. Further, when the locking member 331 and the limiting part 13 need to be unlocked after cleaning, an unlocking device 332 is required. The unlocking device 332 can be an elastic device, such as a spring, a spring, a torsion spring, etc., or it can be the cooperation of the motor 2311 and the connecting rod, and the motor 2311 drives the connecting rod to push the cleaning mechanism 30 out of the cleaning tank 111.Correspondingly, the locking element 331 is unlocked from the limiting part 13. For magnetic connection, plug-in connection, etc., the driving component 231 can directly drive the mop 233 to disengage from the cleaning tank 111, and the locking element 331 is separated from the limiting part 13 by the thrust of the unlocking device 332, thereby achieving the unlocking effect; for the buckle connection, latch connection, etc., the driving component 231 needs to first press a certain distance toward the direction of the mop 233, so that the locking element 331 and the limiting part 13 are located at the position to be unlocked, and then the mop 233 is driven to disengage from the cleaning tank 111, and the locking element 331 is separated from the limiting part 13 by the thrust of the unlocking device 332, thereby achieving the unlocking effect. After unlocking, the unlocking device 332 can further push the cleaning mechanism 30 to the initial position, thereby achieving the reset of the cleaning net cover 31 and the locking component 33.

[0049] In this embodiment, the cleaning steps of the mop 233 of the cleaning robot 1 are as follows: first, the host 20 enters the accommodating chamber 11 and is located above the cleaning tank 111. The driving component 231 drives the mop 233 to move downward, the mop 233 contacts the cleaning net cover 31 and continues to move downward to drive the locking component 33 to move downward, and the locking component 33 triggers the pressing unlocking device 332; the locking element 331 reaches the position of the limit part 13 and locks it, and the driving component 231 stops moving downward; the mop 233 starts to rotate and fits the cleaning net cover 31 in the cleaning tank 111 for cleaning; after cleaning, the driving component 231 drives the mop 233 to move down a distance and then move up or directly move up, the unlocking device 332 triggers and continuously presses the locking component 33, the locking element 331 is separated from the limit part 13, and the cleaning net cover 31 and the locking component 33 move up to the initial position. After the above steps are completed, it is a cleaning process of the mop 233.

[0050] The technical solution of the present invention is to set a mopping mechanism 23 located on the main body of the cleaning robot 1, and the mopping mechanism 23 includes a driving component 231 and a mop 233, and a cleaning mechanism 30 is set in the cleaning tank 111 of the base station 10, and the cleaning mechanism 30 includes a cleaning mesh cover 31 and a locking component 33, one end of the locking component 33 is connected to the cleaning mesh cover 31, and the other end is provided with a locking piece 331, the driving component 231 drives the mop 233 to move to push the cleaning mesh cover 31 to move and the locking piece 331 to lock or disengage from the limiting portion 13, the unlocking device 332 is arranged at the bottom of the cleaning tank 111, and is arranged corresponding to the cleaning mesh cover 31, so that the host 20 can drive the mop 233 to move through the driving component 231 to switch between the cleaning state and the dehydration state. When in the cleaning state, the driving component 231 drives the mop 233 to extend into the cleaning tank 111 to press against the cleaning net cover 31 and push the locking piece 331 to lock with the limiter 13, and the cleaning net cover 31 presses the unlocking device 332; when in the dehydration state, the driving component 231 drives the mop 233 to extend out of the cleaning tank 111 to detach from the cleaning net cover 31, the locking piece 331 is unlocked with the limiter 13, and the unlocking device 332 pushes the cleaning mechanism 30 to extend out of the cleaning tank 111. In the cleaning state, the mop 233 can abut against the cleaning net cover 31 to improve the cleaning effect; after cleaning, the mop 233 and the cleaning net cover 31 can be removed from the cleaning tank 111 to prevent the mop 233 from being continuously in the cleaning tank 111, so as to achieve the separation of the mop 233 from the sewage after cleaning and avoid secondary contamination of the mop 233.

[0051] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the locking assembly 33 also includes a pressing piece 333, the locking piece 331 is a latch, one end of the pressing piece 333 is movably inserted into the cleaning mesh cover 31, and is located on one side of the driving assembly 231, and the other end of the pressing piece 333 is connected to one end of the latch, and the driving assembly 231 presses the pressing piece 333 to move to push the other end of the latch to lock or disengage from the limiting portion 13.

[0052] The pressing member 333 may be a key, a button, etc. In the present embodiment, the pressing member 333 is a "T"-shaped key, that is, it includes two parts arranged vertically, the upper part is a disc, and the lower part is a long rod, one end of the long rod is movably inserted from the cleaning mesh cover 31 to the locking member 331, and one end of the disc is located on one side of the driving assembly 231, and the driving assembly 231 presses one end of the disc to drive one end of the long rod to move. Further, the locking member 331 is a latch, and the corresponding limiting portion 13 is a jack or slot, the middle part of the latch can be rotatably connected to the cleaning mesh cover 31, and one end of the latch is rotatably connected to one end of the long rod of the pressing member 333, and then when the pressing member 333 moves, one end of the latch rotates and then drives the other end to rotate relative to the cleaning mesh cover 31, and then the other end of the latch can rotate and be inserted into the limiting portion 13 or detach from the limiting portion 13, so that the driving assembly 231 drives the pressing member 333 to move and drive the locking member 331 to lock or detach from the limiting portion 13.

[0053] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the locking assembly 33 further includes a connecting shell 337, the bottom wall of the cleaning tank 111 is provided with a connecting slot 1111, the side wall of the connecting slot 1111 is provided with a limiting portion 13, one end of the connecting shell 337 is connected to the cleaning net cover 31, and the other end is movably arranged in the connecting slot 1111;

[0054] The latch is rotatably connected to the inner wall of the connecting shell 337, and the other end of the pressing member 333 is passed through the connecting shell 337 and is rotatably connected to one end of the latch. A connecting hole 3371 is provided on the side of the connecting shell 337, and the pressing member 333 pushes the latch to rotate so that the other end thereof passes through the connecting hole 3371 and is locked or disengaged from the limiting portion 13.

[0055] In this embodiment, one end of the connection shell 337 is connected to the cleaning net cover 31, and the other end is movably inserted into the connection groove 1111, one end of the long rod is movably inserted into the connection shell 337, and one end of the disc is located outside the connection shell 337. The latch is arranged in the connection shell 337, and the middle part of the latch is rotatably connected to the inner wall of the connection shell 337. A connection hole 3371 is provided on the side of the connection shell 337, and then the other end of the latch can be rotatably inserted into the connection hole 3371 and inserted into the limiting part 13 or separated from the limiting part 13, so that the driving component 231 drives the pressing member 333 to move and drive the locking member 331 to lock or separate from the limiting part 13. In addition, the connection shell 337 can have a fixing effect on the position of the button and the locking member 331, maintain the position of the button and the locking member 331, and then ensure the locking effect of the locking member 331 and the limiting part 13.

[0056] In one embodiment of the present invention, Figure 2 , Figure 3As shown, a mounting hole 311 is opened in the middle of the cleaning net cover 31, one end of the connecting shell 337 is connected to the hole wall of the mounting hole 311, and the locking assembly 33 also includes a first elastic member 335, which is sleeved on the pressing member 333 and located between one end of the pressing member 333 and one end of the connecting shell 337.

[0057] A mounting hole 311 is provided in the middle of the cleaning net cover 31, and one end of the connecting shell 337 is connected to the hole wall of the mounting hole 311. In this way, the connecting shell 337 can be fixed at the position of the cleaning net cover 31, and the locking component 33 can be passed through the cleaning net cover 31 and set in the connecting shell 337, so that the locking component 33 and the cleaning net cover 31 can move synchronously, thereby achieving the effect of keeping the locking component 33 fixed at the same time as the cleaning net cover 31 when being locked.

[0058] Furthermore, the locking assembly 33 also includes a first elastic member 335, which can be a spring, a spring sheet, etc. The first elastic member 335 is sleeved on the pressing member 333 and is located between one end of the pressing member 333 and one end of the connecting shell 337. Thus, the first elastic member 335 can have an elastic reset effect on the pressing member 333. When the driving assembly 231 is disengaged from the cleaning mechanism 30, the pressing member 333 can be automatically reset to facilitate pressing during the next cleaning. On the other hand, when the locking member 331 is a latch, the latch is disengaged from the connecting hole 3371 and the limiting portion 13 after the pressing member 333 is pressed down. In order to ensure that the latch can be automatically reinserted into the connecting hole 3371 and the limiting portion 13 after the pressing member 333 cancels the force, the first elastic member 335 can keep the latch automatically reinserted, so that the latch can be plugged into different limiting portions 13 when the locking assembly 33 is located at different positions, thereby ensuring the locking effect of the latch and the limiting portion 13.

[0059] In one embodiment of the present invention, Figures 2 to 5 As shown, the unlocking device 332 includes a support seat 3321 and a second elastic member 3323 . The support seat 3321 is disposed at the bottom of the connecting groove 1111 , and the second elastic member 3323 is disposed between the support seat 3321 and the bottom wall of the connecting groove 1111 .

[0060] The second elastic member 3323 may be a spring, a spring sheet, etc. The second elastic member 3323 is disposed between the support seat 3321 and the bottom wall of the connecting groove 1111. The support seat 3321 is disposed at the bottom of the connecting groove 1111, one end of which is connected to the second elastic member 3323, and the other end of which can abut against the downwardly moved connecting shell 337. When in the cleaning state, the downward movement of the connecting shell 337 can press down the support seat 3321, thereby compressing the second elastic member 3323; when the cleaning is completed, when the driving assembly 231 moves upward, the second elastic member 3323 is restored and exerts an upward thrust on the connecting shell 337, i.e., the locking assembly 33 and the cleaning net cover 31, thereby enabling the cleaning mechanism 30 to be moved upward for resetting, so that the cleaning net cover 31 can be separated from the cleaning groove 111, and the next cleaning can be achieved.

[0061] Furthermore, a mounting groove is provided at the bottom of the connecting groove 1111, and the cross-sectional shape of the mounting groove is larger than the cross-sectional shape of the connecting groove 1111 and is consistent with the cross-sectional shape of the supporting seat 3321, and the unlocking device 332 is arranged in the mounting groove. By setting the height of the mounting groove, the rebound height of the unlocking device 332 can be changed, thereby limiting the range of motion of the supporting seat 3321, limiting the rebound height, and limiting the thrust range of the unlocking device 332.
