[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 brush head fixing structure of an electric cleaning brush, including an electric cleaning brush body 10, and a bristle fixing plate 20 for fixing bristles 30; a motor 11 is provided in the electric cleaning brush body 10, a plug-in portion 12 is fixed to the main shaft of the motor 11, a plug-in hole 21 is provided in the middle of the bristle fixing plate 20, a card slot 22 is provided on the inner side wall of the plug-in hole 21, and an elastic clip 13 is provided on the side wall of the plug-in portion 12, and when the plug-in portion 12 is inserted into the plug-in hole 21, the elastic clip 13 is snapped into the card slot 22.

[0021] like Figures 1 to 6 As shown, when the plug-in part 12 is inserted into the plug-in hole 21, the elastic buckle 13 is inserted into the card slot 22, the motor 11 drives the plug-in part 12 to rotate, and the plug-in part 12 drives the bristle fixing disk 20 to rotate; when the bristle fixing disk 20 needs to be replaced, the plug-in part 12 is taken out from the plug-in hole 21, and the plug-in part 12 is inserted into the plug-in hole 21 of another bristle fixing disk 20, so as to facilitate the replacement of the bristle fixing disk 20.

[0022] like Figures 1 to 6 As shown, the plug hole 21 is a polygonal hole, and the shape of the plug portion 12 matches the shape of the plug hole 21. The plug portion 12 is firmly fixed to the plug hole 21 to prevent the bristle fixing plate 20 from rotating relative to the plug portion 12.

[0023] like Figures 1 to 6 As shown, a groove 121 is provided on the side of the plug-in portion 12, and the elastic buckle 13 is located in the groove 121. The surface of the elastic buckle 13 protrudes out of the groove 121. When the plug-in portion 12 is inserted into the plug-in hole 21, the elastic buckle 13 is clamped into the clamping groove 22. The elastic buckle 13 has a certain elasticity, and the elastic buckle 13 can be clamped in the clamping groove 22. When the bristle fixing plate 20 needs to be replaced, the plug-in portion 12 is pulled out of the plug-in hole 21 under the action of external force, and the elastic buckle 13 is separated from the clamping groove 22.

[0024] like Figures 1 to 6 As shown, the plug hole 21 is a hexagonal hole, and the cross section of the plug portion 12 is a hexagonal shape.

[0025] like Figures 1 to 6 As shown, the elastic buckle 13 includes an elastic sheet 131 and a protrusion 132 arranged at the end of the elastic sheet 131. The cross-section of the protrusion 132 is triangular, and the upper end surface of the slot 22 is an inclined surface. When the plug-in portion 12 is inserted into the plug-in hole 21, the inclined surface of the protrusion 132 contacts the inclined surface of the slot 22.

[0026] The above is a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications are also considered to be within the protection scope of the present utility model.
