[0018] As Figures 1-6 shown, the utility model discloses a liftable cleaning device for floor cleaning robot.

[0019] This cleaning device contains the base 1 and the cover plate 2 of mutual splicing, and the combination of base 1 and cover plate 2 is composed of the cavity of placing inner retraction mechanism, and the bottom of cavity is open structure, and one end of inner retraction mechanism is set in the cavity through bearing;

[0020] The inner retraction mechanism comprises an inner core 3, a connecting plate 4, and an outer shell 5 sleeved on the inner core 3, one end of the outer shell 5 is connected with the cloth assembly, the other end is an open structure, the inner core 3 is located in the outer shell 5, and the connecting plate 4 is arranged on the open structure and connected with the outer shell 5, wherein a plurality of threaded grooves 51 are arranged in the outer shell 5, a plurality of inclined sliding blocks 31 are arranged on the outer circumferential surface of the inner core 3, the inclined sliding blocks 31 are in sliding connection with the threaded grooves 51, and a limiting portion 41 abutting against the inclined sliding blocks 31 is arranged on the connecting plate 4; the purpose is to integrate the functions of the mechanism for driving the cloth assembly to lift and the mechanism for driving the cloth assembly to rotate, so that the use of the two mechanisms can be saved, and the structure of the cleaning device is more simple, practical and low in cost.

[0021] The specific use process of the extension is as follows: the inner core 3 is reversely rotated to separate the outer shell 5 from the inner core 3, the outer shell 5 moves close to the ground, and when the inner core 3 is reversely rotated, the inclined sliding blocks 31 on the circumferential surface of the inner core 3 will touch the limiting portion 41 at the end of the threaded groove 51 and apply pressure to the limiting portion 41, the limiting portion 41 is arranged on the connecting plate 4, and the connecting plate 4 is connected with the outer shell 5, so that the entire outer shell 5 is rotated to drive the cloth assembly to rotate.
