A floor brush as shown in fig. 1-3, which comprises a floor brush body 1, and an elbow pipe assembly 2 rotatably connected with the floor brush body 1. Wherein:

the brush body 1 is provided with a suction channel 10. Specifically, the method comprises the following steps: the floor brush main body 1 comprises a base 11 and an upper cover 12 covering the upper part of the base 11, wherein a suction opening 110 is formed in the base 11, one end of a suction channel 10 is communicated with the suction opening 110, and the other end of the suction channel 10 is communicated with the elbow assembly. In this embodiment: the base 11 is provided with a rotation connecting portion 111, and the rotation connecting portion 111 is used for being rotatably connected with the elbow assembly.

The bent pipe component 2 extends into the floor brush main body 1 from the rear part of the floor brush main body 1 and is rotatably connected with the floor brush main body 1. Specifically, the method comprises the following steps: the elbow assembly 2 includes an elbow bracket 20, and a pipe body 21 disposed on the elbow bracket 20, the pipe body 21 being communicated with the other end of the suction passage 10. In this embodiment: the elbow support 20 includes an elbow main body 200 and an elbow connection member 201, the elbow connection member 201 is located on two sides of the pipe body 21 and extends to the front portion of the elbow main body 200, one end of the elbow connection member 201 is fixed to the elbow main body 200, the other end of the elbow connection member 201 is provided with a rotation connection portion 202, and the rotation connection portion 202 is used for being rotatably connected to the floor brush main body 1.

In this embodiment: the rotation connecting portion 111 of base 11 adopts the shaft hole, and the rotation connecting portion 202 of return bend connecting piece 201 adopts the pivot, and return bend connecting piece 201 of return bend subassembly 2 stretches into to inside the scrubbing brush main part 1, and the pivot of return bend connecting piece 201 and the shaft hole cooperation of base 11 for return bend support 20 can relatively scrubbing brush main part 1 rotates on the upper and lower direction, and the headspace between base 11, the upper cover 12 of scrubbing brush main part 1 allows return bend support 20 to relatively scrub brush main part 1 and realize rotating. In addition, rollers 22 are connected to both sides of one end of the elbow connector 201 as shown.

The floor brush further comprises a rotation limiting part 3 for limiting the upward rotation of the elbow support 20 relative to the floor brush main body 1, and the rotation limiting part 3 is arranged between the floor brush main body 1 and the elbow support 20.

In this embodiment: the upper cover 12 is provided with two fixing opening portions 120, one end of the rotation limiting member 3 is mounted on the fixing opening portion 120 of the upper cover 12, and if the rotation limiting member is clamped in the fixing opening portion 120, the other end of the rotation limiting member 3 abuts against the upper surface of the elbow connecting member 201 of the elbow bracket 20.
