The roller brush driving mechanism 3 drives the main roller brush 2 to rotate. The roller brush driving mechanism 3 and the main roller brush 2 are conventional technologies of sweepers and are not the invention points of this patent, so the specific principles are not described in detail. A left cleaning pad mechanism 4 and a right cleaning pad mechanism 5 are installed at the bottom of the large base plate 1. The left cleaning pad mechanism 4 has the same structure as the right cleaning pad mechanism 5. The left cleaning pad mechanism 4 is located on the left side of the main roller brush 2, and the right cleaning pad mechanism 5 is located on the right side of the main roller brush 2. A reciprocating driving mechanism 6 is installed above the large base plate 1.

The first motor seat 61 is fixedly installed above the large bottom plate 1, and the first motor 62 is installed on the side of the first motor seat 61. The first motor 62 drives the eccentric adjustment block 64 to rotate through the first synchronous belt assembly 63 (the synchronous belt assembly is composed of two synchronous wheels and a synchronous belt, one synchronous belt is installed on the output shaft of the first motor 62, and the other synchronous belt is installed on the input shaft of the eccentric adjustment block 64, and the two synchronous wheels are connected by a synchronous belt transmission). The eccentric adjustment block 64 drives the reciprocating base 66 to reciprocate in the left and right directions through the eccentric assembly 65. The left side of the reciprocating base 66 is connected to the left connecting plate 67, and the left cleaning pad mechanism 4 is installed below the left connecting plate 67. The right side of the reciprocating base 66 is connected to the right connecting plate 68, and the right cleaning pad mechanism 5 is installed below the right connecting plate 68.

[0024] like Figure 4 As shown, the eccentric assembly 65 includes an eccentric block 651, a choke shaft 652, a choke slide 653, a first slider 654, and a first guide rail 656. The eccentric block 651 is eccentrically installed in the eccentric adjustment block 64. The eccentric block 651 is connected to one end of the choke shaft 652, and the other end of the choke shaft 652 is rotatably connected to the choke slide 653. The first slider 654 is fixedly installed on the side of the choke slide 653, and the first slider 654 is slidably connected to the first guide rail 656. The first guide rail 656 is vertically installed in the middle position of the reciprocating base 66. When the eccentric block 651 rotates, the choke slide 653 will move up, down, left and right accordingly.

[0025] like Figure 5-7As shown, the left cleaning pad mechanism 4 includes a slide rail fixing member 41, a linear bearing 42, a guide column 43, a second guide rail 44, a second slider 45, a cleaning pad mounting plate 46, a pad 47, and a cleaning pad 48. A slide rail fixing member 41 is installed on the front and rear sides of the left connecting plate 67, and a linear bearing 42 is installed on the inner side of each slide rail fixing member 41. The linear bearing 42 is movably mounted on the guide column 43. The guide column 43 is installed at the bottom of the large bottom plate 1. The second guide rail 44 is installed on the outer side of the slide rail fixing member 41. The second guide rail 44 is slidably connected to the second slider 45.

A roller 412 is installed on the bottom plate of the pad 47, and the roller 412 extends into the air avoidance groove 48a. When the sweeper is placed on the ground for use, the cleaning pad 48 and the roller 412 contact the ground. Due to the guiding effect of the second guide rail 44 and the second slider 45, the cleaning pad mounting plate 46 will be pushed up to a high position by the ground. When the cleaning pad 48 reciprocates left and right, the cleaning pad mounting plate 46 will be slightly up and down due to the force, and the tension spring 411 pulls the cleaning pad mounting plate 46.
