[0036] In a preferred embodiment, please refer to Figure 6 The first shaft assembly 800 includes a first spline inner shaft 801 and a first keyway outer shaft 804. A first shaft end plate 803 is fixedly disposed on the first spline inner shaft 801.

The two ends of the first tightening spring 802 are fixed between the first shaft end plate 803 and the second shaft end plate 805.

[0037] In this embodiment, the shaft of the first spline inner shaft 801 near the end of the first shaft end plate 803 is rotatably mounted on one side of the inner wall of the movable frame 100. By the push of the first clamping spring 802, the first keyway outer shaft 804 elastically pushes and slides on the first spline inner shaft 801.

[0040] In this embodiment, the drive ring frame 1001 is fixed on the outer ring of the third shaft end plate 903. The elastic force of the first clamping spring 802 is greater than that of the second clamping spring 904. Through the pushing of the first clamping spring 802, the roller 1005 on the drive ring frame 1001 abuts against the corrugated rail 1004. The corrugated rail 1004 is fixed in the seat groove on the inner wall of the movable frame 100.

[0041] The working principle of this invention is as follows: A soft bristle brush roller assembly 400 is provided inside the movable frame 100. The soft bristle brush roller assembly 400 is installed in the movable frame 100 by a push-and-lock snap-fit ​​mechanism via a first shaft assembly 800 and a second shaft assembly 900. When installing the soft bristle brush roller assembly 400, one end of the brush roller 501 is inserted into the first splined inner shaft 801 and pushed backward onto the first keyway outer shaft 804. At this time, it is necessary to ensure that the first keyway locking block 806 is locked in the brush roller keyway 503 at one end of the brush roller 501. During the process of pushing the first keyway outer shaft 804 backward, the first pressing spring 802 will be compressed. At the same time, the other end of the brush roller 501 is inserted into the second splined inner shaft 905. Push the second keyway outer shaft 901 upwards and backwards. At this time, it is necessary to ensure that the second keyway locking block 902 is locked in the brush roller keyway 503 at the other end of the brush roller 501. During the process of pushing the second keyway outer shaft 901 backwards, the second clamping spring 904 will be compressed. In this way, the soft bristle brush roller assembly 400 can be quickly installed and removed on the moving frame 100. At the same time, through this improved installation method, the brush roller assembly 500 has the function of lateral movement between the first shaft assembly 800 and the second shaft assembly 900. While moving laterally, it does not affect the axial drive of the first shaft assembly 800 and the second shaft assembly 900 on the brush roller assembly 500.

[0042] In use, the first shaft assembly 800 rotates, driving the brush roller assembly 500 to rotate. The rotation of the brush roller assembly 500, in turn, drives the rotation of multiple soft brush assemblies 600 on it, thus enabling the soft brush assemblies 600 to clean the floor or ground. Simultaneously with the rotation of the brush roller assembly 500, an auxiliary drive assembly 1000 is mounted on the second shaft assembly 900. The drive ring frame 1001 is fixed to the outer ring of the third shaft end plate 903. The elastic force of the first clamping spring 802 is greater than that of the second clamping spring 904. Through the pushing action of the first clamping spring 802, the rollers 1005 on the drive ring frame 1001 are driven... When the brush roller assembly 500 rotates, it contacts the corrugated track 1004. At this time, the roller 1005 moves back and forth on the concave and convex track of the corrugated track 1004. The brush roller assembly 500 then slides laterally back and forth between the first shaft assembly 800 and the second shaft assembly 900. In this way, the soft brush assembly 600 on the brush roller assembly 500 moves laterally, thereby realizing the lateral wiping action of the soft brush assembly 600. Through this technological improvement, the lateral wiping action of the soft brush assembly 600 is realized on the basis of the soft sweeping without adding extra power.

[0043] In use, the soft brush assembly 600 is locked onto the brush roller assembly 500 by a first pressing action of the implantation seat assembly 700, and the soft brush assembly 600 is unlocked from the brush roller assembly 500 by a second pressing action of the implantation seat assembly 700. This method facilitates the quick removal and installation of the soft brush assembly 600 from the brush roller assembly 500, and facilitates the rapid implantation, use, and replacement of the soft brush assembly 600 on the brush roller assembly 500. The specific installation and removal process is as follows: During installation, the soft brush assembly 600... The main arm 603 on the 0 is inserted into the implantation slot 701. At this time, the second conical slide 607 at the bottom of the support arm 604 first contacts the conical locking block 706. Due to the contact between the inclined surfaces, the conical locking block 706 is pressed backward and the push spring 707 is compressed. After the second conical slide 607 passes the conical locking block 706, the push spring 707 quickly returns to its original position and pushes the conical locking block 706 to its original position. At this time, the conical locking block 706 is locked between the second conical slide 607 and the first conical slide 605. In this way, the... The soft brush assembly 600 is quickly installed and locked onto the brush roller assembly 500. When disassembling, pressing the soft brush assembly 600 again causes the main arm 603 to slide into the insertion groove 701. At this time, the first conical slide 605 presses down on the conical locking block 706 and forces it back. When the first conical slide 605 passes the conical locking block 706, a combined structure with sloping surfaces on both the top and bottom is formed between the first and second conical slides 605. At this point, the soft brush assembly 600 is pulled outwards. At this time, the conical locking block 706 first slides on the upper slope of the first conical slide 605, and then slides against the lower slope of the second conical slide 607. Through this combined structure with slopes on both the upper and lower sides, the conical locking block 706 no longer locks the first conical slide 605 and the second conical slide 607, thereby enabling the soft brush assembly 600 to be quickly removed from the brush roller assembly 500. In this way, it is convenient to quickly replace and install the soft brush assembly 600 from the brush roller assembly 500, thus facilitating replacement after long-term wear.

[0044] It should be emphasized that the first shaft assembly 800 serves as the main drive shaft for driving the brush roller assembly 500. The first shaft assembly 800 is connected to the drive unit inside the movable frame 100. The specific driving method of the first shaft assembly 800 is conventional technology in the field, so it will not be described in detail. The second shaft assembly 900 serves as the auxiliary drive shaft for driving the brush roller assembly 500 and is rotatably mounted on the inner wall of the movable frame 100.

[0045] It should be emphasized that the soft brush bristles 602 are made of conductive yarn, which has wear-resistant and anti-static functions. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
