[0003] The utility model with the publication number CN214631942U discloses a power supply connection structure of a vacuum cleaner floor brush. By using the dust cup provided with a first pin socket and a second pin as an energization transfer, it can ensure that the wire joints are in more stable and reliable contact, and the wires are routed inside the dust cup, which is safer and more reliable;

[0004] However, the above power supply connection structure for the vacuum cleaner floor brush still has the following problems in actual use: Although the conductive connection between the vacuum cleaner and the floor brush is realized through the first pin socket and the second pin, there is no effective positioning mechanism between the first pin socket and the second pin during the connection process, which makes it easy to cause misalignment and bending during installation and force application. At the same time, there is no effective locking mechanism between the vacuum cleaner and the floor brush, which may lead to easy detachment during use.

[0005] Therefore, we propose an electric brush structure of a vacuum cleaner to solve the problems mentioned above. Content of the Utility Model

[0026] Please refer to Figures 1 - 5 , the present invention provides the following technical solutions:

[0027] Embodiment 1: To solve the problems existing in the connection between the existing vacuum cleaner body 1 and the electric brush body 2, the following technical solutions are adopted in this embodiment. An electric brush structure of a vacuum cleaner includes a vacuum cleaner body 1 and an electric brush body 2 detachably installed at the left end of the vacuum cleaner body 1. An air intake insertion tube 3 for sucking dust is connected to the left end of the vacuum cleaner body 1, and a circulation insertion tube 4 for dust transportation is connected to the right end of the electric brush body 2. An electric plug-in component 9 is arranged above the right end of the electric brush body 2, and the right end length of the circulation insertion tube 4 is greater than the right end length of the electric plug-in component 9.

[0028] A power supply component 10 is arranged above the left end of the vacuum cleaner body 1, and the left end length of the power supply component 10 is less than the left end length of the air intake insertion tube 3. When the vacuum cleaner body 1 is connected to the electric brush body 2, positioning is achieved through the air intake insertion tube 3 and the circulation insertion tube 4. A positioning groove structure is arranged between the circulation insertion tube 4 at the right end of the electric brush body 2 and the electric plug-in component 9. When the air intake insertion tube 3 at the left end of the vacuum cleaner body 1 is installed, it is inserted into the positioning groove structure at the right end of the electric brush body 2. The positioning groove structure includes a locking protrusion 5 fixedly connected to the electric plug-in component 9 and arranged above the circulation insertion tube 4. A locking groove 6 is opened above the air intake insertion tube 3 at the left end of the vacuum cleaner body 1. Through the concave-convex locking and positioning between the locking groove 6 and the locking protrusion 5, the connection stability between the vacuum cleaner body 1 and the electric brush body 2 is improved.

[0029] As Figures 1 - 3 shown, when the vacuum cleaner body 1 needs to be connected to the electric brush body 2, first insert the protruding circulation insertion tube 4 at the right end of the electric brush body 2 into the protruding air intake insertion tube 3 at the left end of the vacuum cleaner body 1, so that the circulation insertion tube 4 enters the inside of the air intake insertion tube 3, and the air intake insertion tube 3 is sleeved outside the circulation insertion tube 4 to ensure an initial positioning and guiding effect.

[0030] At the same time, during the insertion process, the upper end of the air intake insertion tube 3 enters the positioning groove structure opened between the circulation insertion tube 4 at the right end of the electric brush body 2 and the electric plug-in component 9. The locking protrusion 5 fixedly installed on the bottom surface of the electric plug-in component 9 in the positioning groove structure abuts against the top surface of the air intake insertion tube 3 and enters the locking groove 6 opened above the air intake insertion tube 3, so as to lock and position between the vacuum cleaner body 1 and the electric brush body 2 through the locking groove 6 and the locking protrusion 5, thereby improving the connection stability during use.

[0031] Embodiment 2: To solve the problems existing in the connection between the existing vacuum cleaner body 1 and the electric brush body 2, the following technical solution is adopted in this embodiment.
