[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5This utility model provides a technical solution: a vacuum cleaner floor brush, including a housing 1, a cleaning brush 11 inside the housing 1, a movable component inside the housing 1, and a replaceable component inside the housing 1. The movable component includes a first vertical plate 21 fixedly connected to one side wall of the housing 1, a movable groove 22 formed on one side of the first vertical plate 21, a movable block 23 connected to the movable groove 22, a first screw 24 connected to the movable block 23, a first motor 25 fixedly connected to the top of the first screw 24, a movable seat 26 fixedly connected to one side of the movable block 23, and a support component for improving the moving stability of the movable seat 26. The first screw 24 is screwed to the movable block 23 and rotatably connected to the first vertical plate 21. The first motor 25 is fixedly connected to the first vertical plate 21. When the first motor 25 is started, the first screw 24 rotates, thereby driving the movable block 23. The vertical movement of the moving block 23 can drive the moving seat 26 to move vertically, which in turn can drive the cleaning brush 11 to move vertically, allowing it to be removed from the housing 1, thus facilitating the maintenance and replacement of the cleaning brush 11. The supporting components include a second vertical plate 51 fixedly connected to the inner wall of the housing 1 away from the first vertical plate 21, a support groove 52 opened on one side of the second vertical plate 51, and a support block 53 slidably connected to the support groove 52. The support block 53 is fixedly connected to the moving seat 26. When the moving seat 26 moves vertically, it can drive the support block 53 to move synchronously. The support block 53 can provide vertical support for the moving seat 26, preventing the moving seat 26 from tilting when moving vertically. The cleaning brush 11 is provided with a cleaning cotton 111 on the outside. The cleaning cotton 111 is fixedly connected to the cleaning brush 11. The cleaning cotton 111 can adhere to impurities on the ground, which can improve the cleaning performance.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5The replaceable components include a through-hole 31 at the bottom of the movable base 26, sliders 32 connected to both sides of the through-hole 31, a support plate 33 fixedly connected to the bottom of the sliders 32, a drive shaft 34 connected to the support plate 33, connection ports 35 on both sides of the cleaning brush 11, and a bidirectional screw 36 connected to the sliders 32. The bidirectional screw 36 is screwed to the sliders 32 and rotatably connected to the movable base 26. The sliders 32 are slidably connected to the through-hole 31, and the drive shaft 34 is rotatably connected to the support plate 33. Rotation of the bidirectional screw 36 can drive the two sliders 32 to move in opposite directions, thereby controlling the two support plates 33 to move in opposite directions, which in turn can drive the drive shaft 34 to move. When the drive shaft 34 disengages from the connection port 35, it can release the cleaning brush 11. When the drive shaft 34 is inserted into the connection port 35, it can move the cleaning brush 11. 1. For quick fixation, an anti-rotation groove 41 is provided on the inner wall of the connection port 35. An anti-rotation plate 42 is fixedly connected to the outer side of the drive shaft 34. The anti-rotation plate 42 is inserted into the anti-rotation groove 41. The anti-rotation plate 42 can be inserted into the anti-rotation groove 41 to ensure that the cleaning brush 11 can rotate synchronously when the drive shaft 34 rotates. A second motor 61 is fixedly connected to one end of the bidirectional screw 36. The second motor 61 is fixedly connected to the inner wall of the through port 31. The second motor 61 can easily drive the bidirectional screw 36 to rotate and provide power for the rotation of the bidirectional screw 36, which can improve the degree of automation. A third motor 71 is fixedly connected to one end of one of the drive shafts 34. The third motor 71 is fixedly connected to the support plate 33. The third motor 71 can easily drive the drive shaft 34 to rotate, which in turn can drive the cleaning brush 11 to rotate, making it easier to clean the floor.

[0026] Working principle: During operation, when the cleaning brush 11 needs to be replaced, the first motor 25 starts, which drives the first screw 24 to rotate. The rotation of the first screw 24 drives the moving block 23 to move down, which in turn drives the moving seat 26 to move down. The movement of the moving seat 26 moves the cleaning brush 11, removing it from the housing 1. Then, the second motor 61 starts, which drives the bidirectional screw 36 to rotate. The rotation of the bidirectional screw 36 drives the two sliders 32 to move to both sides. The movement of the sliders 32 moves the support plate 33, which in turn drives the drive shaft 34 to disengage from the connection port 35, allowing the cleaning brush 11 to be removed. Then, the connection ports 35 on both sides of the new cleaning brush 11 are aligned with the drive shaft 34, and the second motor 61 reverses. The first motor 25 reverses the first screw 24, which in turn moves the two sliders 32 toward the center. The drive shaft 34 is inserted into the connection port 35, and the anti-rotation plate 42 is simultaneously inserted into the anti-rotation groove 41, which can install and fix the cleaning brush 11. The first motor 25 reverses the first screw 24, which in turn moves the moving block 23 upward, which in turn moves the moving seat 26 upward, which in turn moves the cleaning brush 11 upward and resets it. The third motor 71 starts and drives the drive shaft 34 to rotate. Through the anti-rotation plate 42, the cleaning brush 11 can rotate synchronously, which can clean the ground. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
