Cleaning robot

Abstract

A cleaning robot includes a housing including a cover, a base and a pair of lateral plates, a cleaning device and a driver. The cleaning device is mounted on the base to form a tilt angle with ground and includes a connecting member and a cleaning member connected to the connecting member. The cleaning member includes a water storage room mounted on the connecting member and a cleaning portion connected to the water storage room. The driver is mounted on the base and tightly fixed with the connecting member for driving the connecting member to rotate so that the cleaning member is following rotating with the connecting member. The cleaning portion can clean water marks or grease marks on the ground during the cleaning member rotation. Thus, users are not required to clean water marks or grease marks on the ground, thereby the convenience of users is improved.

         7 . The cleaning robot as claimed in  claim 4 , wherein the cleaning portion comprises a cleaning body, a receiving room positioned on a middle portion of the cleaning body for receiving the water storage body therein to form a water storage tank therebetween, and a cleaning cloth positioned on a bottom of the cleaning body. 
     
     
         8 . The cleaning robot as claimed in  claim 7 , wherein the receiving room comprises a receiving recess formed at a first bottom wall thereof, a bottom of the outer periphery of the water storage body inserted into the receiving recess and tightly fixed with the first bottom wall of the receiving recess to tightly connect the water storage room with the cleaning portion. 
     
     
         9 . The cleaning robot as claimed in  claim 8 , wherein the first bottom wall of the receiving room comprises an outlet opening for receiving at least one water seepage portion of the cleaning member therein, and water in the water storage tank can penetrate the cleaning cloth through the water seepage portion so that the cleaning cloth can clean the ground. 
     
     
         10 . The cleaning robot as claimed in  claim 9 , wherein the first bottom wall of the receiving room further comprises at least one retaining wall formed on a sidewall of the receiving recess for preventing the water seepage portion from blocking the outer periphery of the water storage body to tightly fix with the receiving recess. 
     
     
         11 . A cleaning robot comprising:
 a housing comprising a cover, an oval-shaped base connected to the cover, and a pair of lateral plates movably connected to the cover and the base, respectively, and surrounding around a corresponding long outside of the cover and the base;   a driver installed on an upper surface of the base and comprising a gear-box member movably mounted on a short side of the base, the gear-box member comprising a gear-box body fixed with the short side of the base and formed a tilt angle with ground or a lower wall of the base;   a cleaning device movably connected to a bottom surface of the base and tightly fixed with the gear-box body, the cleaning device comprising at least one connecting member movably connected to the base, and at least one cleaning member tightly fixed with the connecting member, the cleaning member defining an inclined contacting surface relative to the ground to form the tilt angle with the ground same as that of the gear-box body and the ground, and comprising a water storage room installed with the connecting member and a cleaning portion mounted on the water storage room; and   when the cleaning member obliquely rotating, a lowest point formed by the cleaning member and the ground created a high strength friction for driving the connecting member to rotate so as to the cleaning member follow rotating with the connecting member; and wherein   water in the water storage room can be immersed into a bottom of the cleaning portion to make the cleaning portion clean water marks or grease marks on the ground during the cleaning member rotation, and the pair of lateral plates can move relative to the base and transmit a signal to the driver which can drive the cleaning device to move for changing a movement direction of the cleaning robot when the pair of lateral plates is touched.
