Water tank and cleaning equipment

The utility model discloses a water tank which comprises a water tank body, and the water tank body is installed at a water tank installation position of cleaning equipment in the non-vertical direction. A first inclined surface is arranged at the bottom of the water tank body; the height of the first inclined surface is gradually reduced along the mounting direction of the water tank. The cleaning equipment comprises a chassis body, and a water tank mounting position is arranged on the chassis body; the chassis body is provided with a third inclined surface, and the third inclined surface is located on the bottom surface of the water tank mounting position, matched with the first inclined surface and used for allowing the first inclined surface to slide along the third inclined surface when the water tank body is mounted. The gravity of the water tank forms stable component force in the installation direction, installation of the water tank is facilitated, and the water tank is prevented from falling off. 本实
