[0017] In order to explain the idea and purpose of the present application, the present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", "left", "right", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] like Figures 1 to 6As shown, the embodiment of the present application provides a rotation structure of an electric cleaning brush, including a brush handle 10, a brush head 20 and a connecting section 30, and also includes an angle adjustment structure 40, the inner side surface of the angle adjustment structure 40 is alternately provided with a plurality of positioning grooves 41, the bottom of the brush handle 10 is rotatably connected to the angle adjustment structure 40, the outer side surface of the bottom of the brush handle 10 is provided with a fixing groove 11 in the vertical direction, a latch 12 and a compression spring 13 are provided in the fixing groove 11, one end of the compression spring 13 is connected to the top of the fixing groove 11, and the other end of the compression spring 13 is connected to the latch 12, the latch 12 is inserted into the positioning groove 41, the angle adjustment structure 40 is fixedly connected to the top of the connecting section 30, the bottom of the connecting section 30 is connected to the brush head 20, and when the brush handle 10 is rotated, the latch 12 is inserted into adjacent positioning grooves 41 in sequence.

[0021] like Figures 1 to 6 As shown, there are two angle adjustment structures 40, which are respectively arranged at both sides of the bottom of the brush handle 10. Under the action of the compression spring 13, the bottom of the latch 12 is inserted into the positioning groove 41, and the brush handle 10 and the connecting section 30 are relatively fixed. When the brush handle 10 is rotated, the bottom of the latch 12 enters the next positioning groove 41, and the brush handle 10 and the connecting section 30 are relatively fixed.
