[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Please also see Figures 1 to 6A floor scrubber brush plate pressure regulating device of this embodiment includes a lifting mechanism 1 and a brush plate mechanism 2. The brush plate mechanism 2 includes a fixed plate 133. A U-shaped bracket 22 is fixedly connected to the fixed plate 133. A counterweight frame 23 is fixedly connected to the U-shaped bracket 22. A counterweight block 24 is fixedly connected to the counterweight frame 23. The counterweight block 24 is used to increase the weight of the fixed block 5, so that when the fixed block 5 moves downward, the position of the fixed block 5 is adjusted through the movement of the output end of the electric push rod 12, thereby controlling the brush plate. The pressure of the brush plate in the mechanism 2 in contact with the ground and the setting of the counterweight block 24 increase the adjustable range of the pressure. The lifting mechanism 1 includes a fixed frame 11, an electric push rod 12 and a sliding assembly 13. The sliding assembly 13 includes a sliding rod 131 and two fixing parts 132. The sliding rod 131 is fixed between the two fixing parts 132. The fixing part 132 facilitates the fixing of the sliding rod 131, so that the sliding rod 131 can be adjusted to a position between the two fixing parts 132. The sliding rod 131 is slidably connected to the fixed frame 11. The electric push rod 12 is used to drive the slide bar 131 to move in the horizontal direction. A tension spring 3 is fixedly connected between the fixing portion 132 and the fixing frame 11. The setting of the tension spring 3 enables the fixed block 5 to move vertically downward by gravity when the output end of the electric push rod 12 is retracted, so that the slide bar 131 has a force toward the electric push rod 12 for the output end of the electric push rod 12. The tension spring 3 provides a force away from the electric push rod 12, which is used to reduce the slide bar 131 on the output end of the electric push rod 12 when the fixed block 5 is vertically downward. The influence of the electric push rod 12 can extend the service life of the electric push rod 12. A rope body 4 is fixedly connected between the two fixed parts 132. The rope body 4 is a rope. A fixed block 5 is fixedly connected to the rope body 4. Guide components 6 are respectively provided on the opposite sides of the fixed frame 11. The rope body 4 passes through the guide components 6 to make the fixed block 5 move in the vertical direction. A through hole 51 is opened on the fixed block 5. A fixed rod 221 is fixedly connected between the inner walls on both sides of the U-shaped bracket 22, and the fixed rod 221 passes through the through hole 51.

[0028] Reference Figure 2 The counterweight frame 23 has first waist-shaped holes 231 on opposite sides thereof, through which the fixing rod 221 passes. The first waist-shaped holes 231 are provided to facilitate installation of the counterweight frame 23 .

[0029] Reference Figure 1 , Figure 4 and Figure 6 The fixing portion 132 includes two fixing plates 133, and a second waist-shaped hole 134 is opened on the fixing plate 133, so that the fixing plate 133 is more convenient and stable for fixing the rope body 4 and the tension spring 3. One end of the tension spring 3 on the same side is fixedly connected between the two fixing plates 133, and the two ends of the sliding rod 131 pass through the corresponding second waist-shaped holes 134 respectively. The two ends of the sliding rod 131 are provided with threads and are fixedly connected to the fixing plate 133 by nuts.

[0030] Reference Figure 4 and Figure 5 Two opposite sides of the fixing frame 11 are respectively provided with sliding grooves 111 , and the sliding rod 131 is slidably connected with the sliding grooves 111 , and the sliding grooves 111 provide direction and support force for the movement of the sliding rod 131 .

[0031] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The guide assembly 6 includes a pressing plate 61, a pulley 62 is rotatably connected between the pressing plate 61 and the fixing frame 11, and the rope body 4 is wound around the pulley 62, through which transmission can be more conveniently achieved.

[0032] Reference Figure 5 and Figure 6 A limit block 7 is provided between the fixing plate 133 adjacent to the fixing frame 11 and the fixing frame 11. The limit block 7 is fixedly connected to the slide bar 131. The rope body 4 includes a first stretching section 41 and a second stretching section 42. The first stretching section 41 and the second stretching section 42 are the parts of the rope body 4 located between the pulley 62 and the fixing portion 132. The limit block 7 makes the first stretching section 41 and the second stretching section 42 parallel to each other, so that the first stretching section 41 and the second stretching section 42 slide stably on the pulley 62, and prevents the first stretching section 41 and the second stretching section 42 from sliding out of the pulley 62. The central axis position of the pulley 62 is lower than the position of the slide bar 131, so that the first stretching section 41 is parallel to the horizontal plane. The pulling force of the slide bar 131 on the first stretching section 41 and the second stretching section 42 is parallel to the horizontal plane, and the force is used more completely to prevent the decomposition of the force.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The fixed block 5 includes a positioning block 52 and a U-shaped connecting block 53. The positioning block 52 is fixedly connected in the U-shaped connecting block 53, and a through hole 51 is formed between the positioning block 52 and the bottom wall of the U-shaped connecting block 53. Using this structure to form the through hole 51 is more convenient and the processing is relatively simple.

[0034] Reference Figure 2 , Figure 4 and Figure 5 The positioning block 52 is divided into a first fitting block 521 and a second fitting block 522. The first fitting block 521 and the second fitting block 522 have first grooves 523 on opposite sides thereof. The two first grooves 523 form a space for the rope body 4 to pass through. The rope body 4 is passed through the first grooves 523, thereby solving the problem of difficulty in fixing the rope body 4 and the fixing block 5.

[0035] Reference Figure 4 and Figure 5The positioning block 52 is provided with second grooves 524 on both sides of the inner wall close to the U-shaped bracket 22, and the second grooves 524 are adapted to the rope body 4, and a curved surface transition is formed between the second grooves 524 and the through hole 51. The second grooves 524 are provided to reduce the friction between the rope body 4 and the fixing block 5 during the process of the rope body 4 lifting and lowering the fixing block 5, thereby extending the service life of the rope body 4.

[0036] Working principle: when the electric push rod 12 drives the slide bar 131 to move toward the end away from the electric push rod 12, the slide bar 131 pulls the rope body 4, and the rope body 4 moves the fixed block 5 upward through the pulley 62. When the electric push rod 12 drives the slide bar 131 to move toward the end close to the electric push rod 12, the fixed block 5 moves vertically downward by gravity. At this time, the tension spring 3 is stretched to reduce the force of the slide bar 131 against the output end of the electric push rod 12 toward the electric push rod 12. At this time, the pressure of the brush plate in the brush plate mechanism 2 on the ground is constantly changing. The electric push rod 12 is used to make the fixed block 5 rise and fall, so as to adjust the pressure of the brush plate on the ground.
