[0024] Please refer to Figures 1-7 , the utility model provides the following technical scheme: a fast detachable electric brush,

[0025] Embodiment one: in order to solve the problem that the replacement mode of the brush in the prior art is mostly that multiple bolts at the connecting position of the brush and the base 2 are sequentially unscrewed with a tool, so that the brush can be disassembled and replaced, leading to a relatively time-consuming and laborious replacement mode, and the brush is generally in a bare state, leading to dust and impurities in the external environment being easily attached to the surface of the brush, thereby affecting the subsequent cleaning effect, therefore the following scheme is disclosed, and specific reference is made to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 , which comprises a handle part 1, the lower part of the handle part 1 is connected with a base 2, the bottom of the base 2 is provided with a brush body 3, and the upper part inside the handle part 1 is fixed with a motor 6; the inside of the handle part 1 is connected with a rotating rod 5 through a bearing, the top of the brush body 3 is fixedly connected with a mounting block 4, the bottom of the base 2 is provided with a mounting groove 7, the mounting block 4 and the mounting groove 7 are both provided in an inverted "T" shape, and are connected in a clamping mode between the mounting block 4 and the mounting groove 7, the upper part of the two sides of the mounting block 4 is provided with a limiting groove at equal intervals; the inside of the base 2 is connected with a limiting rod 8 at equal intervals on the left and right sides, the connecting position between the outside of the limiting rod 8 and the base 2 is provided with a return spring 9, one end of the limiting rod 8 extends out of the outside of the base 2, and the ends of every two limiting rods 8 are connected through a fixed plate, the limiting rod 8 corresponds to the position of the limiting groove, and is connected in a plug-in mode between the limiting rod 8 and the limiting groove.

[0026] When the brush body 3 is damaged after long-term use, the damaged brush body 3 needs to be replaced. At this time, the user only needs to pull the limiting rods 8 on both sides (the return springs 9 are in a compressed state), so that the limiting rods 8 are separated from the limiting grooves, the limiting of the mounting block 4 is released, and then the brush body 3 is pulled to the left, that is, it can be quickly disassembled from the base 2. Then, the new brush body 3 is clamped into the mounting groove 7 on the base 2 through the mounting block 4, the limiting rod 8 is reset under the elastic force of the return spring 9, and is inserted into the corresponding limiting groove. The limiting rod 8 can limit the mounting block 4 and complete the installation of the brush body 3, so as to facilitate the quick replacement of the brush body 3.

[0027] Example two: different from example one, the rotating rod 5 is driven to rotate by the motor in this embodiment, so that the rotating rod 5 drives the brush body 3 to rotate and clean the ground, thereby improving the cleaning efficiency and quality.
