Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner floor brush for preventing hair entanglement. Background Technique

[0002] A vacuum cleaner is a machine that uses an electric motor to generate air negative pressure to suck dust debris. When the vacuum cleaner sucks dust debris from the ground, a vacuum cleaner floor brush needs to be installed on the vacuum cleaner for direct contact with the ground, and the dust, dirt, etc. on the ground are sucked into the vacuum cleaner through the rotation and friction of the brush head.

[0003] In the prior art, as disclosed in Chinese Patent CN206354985U, a vacuum cleaner and a knife brush for preventing hair entanglement are disclosed. The knife brush includes a blade seat and blades arranged in the blade seat. The upper part of the blade seat is set as a brush tooth structure arranged at intervals. The blades pass through all the brush teeth in the length direction of the blade seat, and the part of the blade between every two adjacent brush teeth is higher than the tooth root of the brush teeth and forms an edge for cutting hair.

[0004] Although the above patent prevents the problem of hair entanglement by installing blades in the vacuum cleaner floor brush to cut the hair wound on the roller, the blades will also consume the brush on the roller during use. Therefore, the roller needs to be replaced after a period of use. However, there is no disassembly structure in the above patent. When the brush on the roller cannot be used, only the whole vacuum cleaner floor brush can be replaced, resulting in waste of resources. Content of the Utility Model

The outer surface of the connecting column 4 is rotatably connected with a rotating cylinder 5. The outer surface of the rotating cylinder 5 is slidably clamped with a rotating brush 10. By rotating the dismantling column 2, the first fixing thread 6 and the second fixing thread 7 are respectively removed along the threads of the second thread groove 9 and the first thread groove 8, the dismantling column 2 is pulled out, and then the rotating brush 10 is slid out from the rotating cylinder 5. A new rotating brush 10 is slidably clamped on the rotating cylinder 5. The connecting column 4 and the dismantling column 2 are inserted into the vacuum cleaner floor brush housing 1, and the dismantling column 2 is rotated in the reverse direction to fix the connecting column 4 and the dismantling column 2 in the vacuum cleaner floor brush housing 1, so as to realize the replacement of the rotating brush 10. This structure is simple, the operation is convenient, and the replacement is rapid, which can prevent waste of resources caused by replacing the whole vacuum cleaner floor brush.

[0022] As Figure 1 - Figure 3 shown, the other side of the dismantling column 2 is fixedly connected with a rotating rod 3. Through the structural design of the rotating rod 3, it is convenient for the user to rotate the dismantling column 2.

[0023] As Figure 1 and Figure 3As shown in the figure, one side of the outer surface of the vacuum cleaner floor brush housing 1 is rotatably connected to a first connecting cylinder 14. One side of the outer surface of the first connecting cylinder 14 is rotatably connected to a second connecting cylinder 15. One end of the second connecting cylinder 15 is fixedly communicated with a hose 13. The other end of the hose 13 is fixedly communicated with one side of the vacuum cleaner floor brush housing 1. Through the structural design of the first connecting cylinder 14 and the second connecting cylinder 15, it is convenient for the user to adjust the position of the vacuum cleaner floor brush on the ground.

[0024] As Figure 1 , Figure 3 and Figure 5 As shown in the figure, on the other side of the outer surface of the vacuum cleaner floor brush housing 1, there is a fixedly connected mounting bracket 11. Inside the mounting bracket 11, there is a blade 18. The outer surface of the mounting bracket 11 is threadedly connected with a plurality of fixing bolts 12. One ends of the fixing bolts 12 are all threadedly connected with one side of the blade 18. Through the structural design of the blade 18, when the vacuum cleaner floor brush is in use, the roller brush 10 rotates, and the hair wound on the roller brush 10 is cut off by the blade 18 during the rotation of the roller brush 10, thereby preventing hair entanglement and affecting the cleaning effect of the vacuum cleaner on the ground.
