Description

Technical Field

[0001] This utility model relates to the field of floor cleaning equipment technology, and in particular to a four-bar linkage dual-brush type floor cleaning structure assembly. Background Technology

[0002] In the field of floor cleaning equipment, the cleaning efficiency, ease of operation, and stability of the floor scrubbing assembly are the core technical indicators. Traditional floor scrubbing equipment mostly adopts a single brush or symmetrical dual brush layout, which can achieve basic scrubbing functions, but has many technical pain points. Existing equipment generally faces the problem of high manual pushing load. Its brushes are mostly set horizontally, and the friction force against the ground is unidirectional. It can only provide cleaning force but cannot form forward auxiliary traction force, which requires operators to continuously apply pushing force, especially in large-area cleaning scenarios where the labor intensity is extremely high. Furthermore, some dual-brush cleaning devices suffer from structural design flaws, leading to uneven force distribution on both sides during cleaning. This causes the device to tilt to one side, affecting the straightness of the cleaning path and the consistency of cleaning quality. Although some devices attempt to adjust the brush height using a lifting mechanism, most employ a single lever or simple hinge design, resulting in insufficient lifting stability and difficulty in adapting to cleaning needs with varying floor flatness. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a four-link dual-brush floor cleaning structure assembly, which solves the technical problems of existing floor cleaning equipment, such as high manual pushing load, lack of forward traction, and uneven force distribution on the left and right sides of the dual-brush structure leading to equipment deviation, affecting the straightness of the cleaning path and the consistency of cleaning quality. It can generate forward traction while cleaning the floor, saving physical strength, and achieve the purpose of left and right balance of the equipment by changing the magnitude and direction of the brush friction vector.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a four-link double-brush floor scrubbing structure assembly, including a floor scrubber, a brush plate cover is provided in the lower middle part of the floor scrubber, motors are symmetrically installed on both sides of the top of the brush plate cover, and the motor connecting shaft passes through the brush plate cover and is connected to a flange, a brush buckle is installed at the bottom of the flange, and a brush for scrubbing the floor is fixedly connected to the bottom of the brush buckle, and double connecting rods are respectively installed on the connecting frame on the motor base on both sides of the top of the brush plate cover by bolts, and the ends of the two double connecting rods are respectively rotatably connected to both sides of the floor scrubber by axle pins, and a single connecting rod is installed at the bottom of the connecting frame by bolts, and a foot pedal lifting rod is connected to one side of the single connecting rod by bolts.

[0005] A further improvement is that the brush cover has a sloping stepped structure, and the two symmetrically arranged brushes are inclined towards the middle of the brush cover.

[0006] A further improvement is that a water-retaining skirt is fixedly connected to the bottom of the brush cover, and water-retaining bristles are provided on both sides of the water-retaining skirt.

[0007] A further improvement is that the water-blocking skirt is a hollow shell structure adapted to the brush disc cover, and its height is lower than the height of the brush.

[0008] A further improvement is that the foot pedal lifting rod includes a connecting rod that is bolted to a single connecting rod. The end of the connecting rod is rotatably connected to the floor scrubber via a pivot pin. A rotating rod is bolted to the end of the connecting rod, and a foot pedal is fixed to the end of the rotating rod.

[0009] A further improvement is that the motor is electrically connected to the main control unit on the floor scrubber.

[0010] By employing the above technical solution, this utility model provides a four-link dual-brush floor scrubbing structure assembly, which has at least the following beneficial effects: 1. This utility model uses two motors to drive the flange and the brushes on the bottom brush buckle to rotate inward relative to each other, thereby achieving the cleaning work of the ground. Because the brush disc cover adopts a sloping step structure, the two brushes are tilted at a certain angle to the middle, changing the magnitude and direction of the frictional force vector on the ground, thereby achieving the left and right balance of the machine and the forward traction force, helping the machine to move forward easily and solving the problem of heavy manual pushing.

[0011] 2. This utility model uses a foot pedal to drive the rotating rod downwards, which, based on the lever principle, drives the connecting rod to rotate on the floor scrubber. This, in turn, drives the brush cover to rise and fall via a single connecting rod, thereby achieving height adjustment of the brush cover to meet the cleaning needs of different floors.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Addressing the issues of existing floor cleaning equipment, such as high manual pushing load, lack of forward traction, and uneven force distribution in the dual-brush structure leading to equipment deviation and affecting the straightness of the cleaning path and consistency of cleaning quality, this embodiment provides a four-link dual-brush floor cleaning structure assembly. This assembly generates forward traction while cleaning, saving physical effort, and achieves lateral balance by changing the magnitude and direction of the brush friction vector. Please refer to... Figures 1-4 The four-link dual-brush floor scrubbing assembly includes a floor scrubber 1. A brush plate cover 2 is located at the lower middle part of the floor scrubber 1. Motors 3 are symmetrically installed on both sides of the top of the brush plate cover 2. The connecting shaft of the motor 3 passes through the brush plate cover 2 and is connected to a flange 4. A brush buckle 5 is installed at the bottom of the flange 4. A brush 6 for scrubbing the floor is fixed to the bottom of the brush buckle 5. Double connecting rods 7 are installed on the connecting frame on the motor base on both sides of the top of the brush plate cover 2 by bolts. The ends of the two double connecting rods 7 are rotatably connected to both sides of the floor scrubber 1 by axle pins. A single connecting rod 8 is installed at the bottom of the connecting frame by bolts. A foot pedal lifting rod 9 is connected to one side of the single connecting rod 8 by bolts.

[0017] The brush cover 2 has a sloping stepped structure, and two symmetrically arranged brushes 6 are inclined towards the middle of the brush cover 2. The two motors 3 are started simultaneously to drive the flange 4 and the brushes 6 on the bottom brush buckle 5 to rotate inward relative to each other, thereby realizing the scrubbing work of the ground. Because the brush cover 2 adopts a sloping stepped structure, the two brushes 6 are tilted at a certain angle towards the middle of the two brushes, changing the magnitude and direction of the friction vector on the ground, thereby realizing the left and right balance of the machine and the forward traction force, helping the machine to move forward easily and solving the problem of heavy manual pushing. In conjunction with the foot pedal lifting rod 9 and the linkage of double connecting rod 7 and single connecting rod 8, the brush cover 2 is driven to lift and lower as a whole to adapt to the cleaning requirements of different ground.

[0018] To prevent the brush 6 from flinging dirt and contaminating the surrounding area during the floor washing process, a water-blocking skirt 10 is fixed to the bottom of the brush cover 2, and water-blocking bristles are provided on both sides of the water-blocking skirt 10.

[0019] The water-blocking skirt 10 is a hollow shell structure that is adapted to the brush cover 2, and its height is lower than that of the brush 6. The water-blocking skirt 10 intercepts the stains that are flung off by the brush 6 during the floor washing process, preventing the stains from being flung to the surrounding area. Together with the water-blocking bristles, it further limits the problem of local stains overflowing from the gaps of the water-blocking skirt 10.

[0020] Specifically, the foot-operated lifting rod 9 includes a connecting rod 91 connected to a single connecting rod 8 by bolts. The end of the connecting rod 91 is rotatably connected to the floor scrubber 1 by a pivot pin. A rotating rod 92 is installed at the end of the connecting rod 91 by bolts, and a foot pedal 93 is fixedly connected to the end of the rotating rod 92. Stepping on the foot pedal 93 causes the rotating rod 92 to press down, which, according to the lever principle, causes the connecting rod 91 to rotate on the floor scrubber 1. This, in turn, causes the brush cover 2 to rise and fall through the single connecting rod 8, thereby achieving height adjustment of the brush cover 2 to adapt to the cleaning needs of different floors.

[0021] Specifically, motor 3 is electrically connected to the main control unit on floor scrubber 1; the main control unit on floor scrubber 1 controls the speed of motor 3 to adapt to the cleaning needs of different floors.
