Cleaning device

Abstract

A cleaning device is provided, which includes a body mechanism, a chassis body, a cleaning assembly, a water tank, and a negative pressure source. A lower end of the body mechanism is rotatably connected to a middle of the chassis body. The cleaning assembly is arranged below the chassis body. The water tank includes a sewage tank and a clean water tank capable of supplying water for cleaning. At least one of the clean water tank and the sewage tank is arranged on the chassis body. The negative pressure source is capable of sucking dirt generated by the cleaning assembly into the sewage tank during cleaning.

         6 . The cleaning device of  claim 5 , wherein,
 an extension direction of the first guiding side wall is the same as the installation direction, or an extension direction of the first guiding side wall forms an angle of less than 10° with the installation direction;   and/or,   the first guiding side wall is one of two first guiding side walls; the two first guiding side walls are arranged to face each other, and a distance between the two first guiding side walls gradually decreases along the installation direction; or, the two first guiding side walls are arranged to face away from each other, and a distance between the two first guiding side walls gradually increases along the installation direction.   
     
     
         7 . The cleaning device of  claim 5 , wherein,
 each side of two sides of the water tank body is provided with the first guiding side wall; or, the first guiding side wall is one of at least two first guiding side walls.   
     
     
         8 . The cleaning device of  claim 1 , wherein,
 the chassis body is provided with a third inclined surface, the third inclined surface is located at a bottom of the water tank installation position, the third inclined surface is matched with the first inclined surface, and the first inclined surface slides along the third inclined surface during installation of the water tank body.   
     
     
         9 . The cleaning device of  claim 8 , wherein,
 a flat surface is connected to an end of the first inclined surface facing away from the installation direction of the water tank and an end of the second inclined surface facing away from the installation direction of the water tank.   
     
     
         10 . The cleaning device of  claim 8 , wherein,
 the chassis body is provided with a fourth inclined surface, the fourth inclined surface is located at a top of the water tank installation position, and the fourth inclined surface is matched with the third inclined surface.   
     
     
         11 . The cleaning device of  claim 8 , wherein,
 part of a bottom of the water tank installation position is protruded upward to form the third inclined surface.   
     
     
         12 . The cleaning device of  claim 8 , wherein,
 the first inclined surface is one of two first inclined surfaces, and the third inclined surface is one of two third inclined surfaces;   one of the two first inclined surfaces and one of the two third inclined surfaces are arranged on a left side of the water tank installation position, and the other one of the two first inclined surfaces and the other one of the two third inclined surfaces are arranged on a right side of the water tank installation position.   
     
     
         13 . The cleaning device of  claim 8 , wherein,
 a roller installation space is defined under the third inclined surface for installation of a first roller body.   
     
     
         14 . The cleaning device of  claim 5 , wherein,
