Description

Technical Field

[0001] The present application relates to the technical field of floor scrubbers, and in particular to a squeegee assembly and a floor scrubber. Background Art

[0002] Floor scrubbers are widely used in large-scale commercial and industrial cleaning scenarios. Combining vacuuming, mopping, and self-cleaning functions, they provide comprehensive floor cleaning in a single operation. Their powerful suction instantly removes dust, hair, and larger debris, leaving floors spotless. Their high-speed rotating brush can penetrate deep into crevices and easily tackle stubborn stains, offering greater cleaning power than traditional mops. The squeegee, the heart of the floor scrubber, directly impacts wastewater recovery efficiency and equipment stability.

[0003] The existing technology still has the following problems:

[0004] 1. The traditional fixed squeegee adopts a rigid structure. When facing uneven ground, the rubber strip does not fit the ground well enough, resulting in a high rate of sewage residue. In addition, the squeegee is prone to collide with obstacles when the floor scrubber is working, causing damage to the squeegee. In serious cases, it affects the instability of the internal parts of the floor scrubber, making it impossible for the floor scrubber to clean the ground.

[0005] 2. The cleaning components of existing floor scrubbers are mostly fixedly installed on the floor scrubbers. When on an inclined ground, the contact between the roller brush disc and the edge of the ground may be uneven. Stubborn stains on the inclined ground may be difficult to be completely removed due to the uneven pressure distribution of the roller brush disc. In addition, the roller brush disc is prone to large friction with the ground, which causes serious wear of the roller brush disc and reduces its service life. Summary of the Invention

The present invention can flexibly fix the squeegee on the floor scrubber through the squeegee assembly, so as to improve the adhesion between the adhesive strip and the ground and improve the sewage removal effect. When on an inclined ground, the contact between the roller brush plate and the edge of the ground may be uneven. The present invention can clean the inclined ground through the cleaning assembly, so that the roller brush plate is evenly stressed when cleaning the inclined ground.

The water-absorbing rubber strip 521 is slidably connected to the inner cavity of the grill 51, the second threaded rod 523 and the grill 51 are connected by threads, and the second spring 524 is located between the adjusting block 522 and the inner wall of the grill 51. By flexibly fixing the water-absorbing rubber strip 521 to the inner cavity of the grill 51, when the water-absorbing rubber strip 521 contacts the uneven ground, the water-absorbing rubber strip 521 and the ground are in contact. The surface fit is higher, which facilitates better removal of sewage. The position of the second threaded rod 523 in the inner cavity of the grill 51 is adjusted by rotating the second threaded rod 523. At this time, the water-absorbing rubber strip 521 is kept in close contact with the ground. At the same time, the adjusting block 522 generates an extrusion force on the second spring 524 on the second threaded rod 523, so that the adjusting block 522 can slide upward or downward on the second threaded rod 523, so that the water-absorbing rubber strip 521 can move when encountering a raised or sunken ground, keeping the bottom end of the water-absorbing rubber strip 521 in close contact with the ground, so that the water-absorbing rubber strip 521 can remove dirt from the raised or sunken ground.

In this way, the anti-collision mechanism 53 is first contacted with the obstacle, that is, the buffer wheel 531 contacts the obstacle first, and the guide cylinder 532 rotates in the inner cavity of the buffer wheel 531 to cooperate with the buffer wheel 531 to rotate on the floating ring 533, so as to guide the obstacle during the collision, thereby reducing the force generated by the collision. At the same time, the buffer wheel 531 is forced to drive the floating ring 533 in the inner cavity of the limit ring 537. At this time, the floating ring 533 drives the first sliding rod 534 to slide in the inner cavity of the slide groove 538. The sliding of the floating ring 533 drives the floating ring 533 to squeeze the third spring 535. Under the elastic force of the third spring 535, the buffer wheel 531 can have a buffering effect during the collision, reducing the subsequent vibration amplitude of the squeegee frame 51, thereby reducing the damage to the squeegee assembly during the collision.

[0037] Example 2:

[0038] Based on the inventive concept of the aforementioned embodiment 1, this application also provides a floor scrubber, please refer to Figure 1As shown, it includes a squeegee assembly, including a washing machine body 1 and a squeegee assembly, a buffer block 541 and an inner cavity of the washing machine body 1 are slidably connected, a second slide bar 542 and an inner cavity of the washing machine body 1 are slidably connected, a fourth spring 543 is located between the buffer block 541 and the inner wall of the washing machine body 1, an adjustment frame 5451 and an upper surface of the washing machine body 1 are fixedly connected, and the rack 51 is flexibly fixed to the washing machine body 1 through the buffer mechanism 54, so as to further reduce the damage of the squeegee assembly when it collides. When the anti-collision mechanism 53 or the rack 51 collides, the buffer block 541 is driven to move in the washing machine body 1 The inner cavity slides, at this time the buffer block 541 drives the second sliding rod 542 to slide in the inner cavity of the floor washing machine body 1 and squeezes the fourth spring 543. The elastic force of the fourth spring 543 causes the buffer block 541 to quickly reduce the shaking amplitude of the inner cavity of the floor washing machine body 1, so that the squeegee assembly can produce a certain floating shaking in the inner cavity of the floor washing machine body 1 when it is hit, while avoiding the damage of the squeegee assembly caused by rigidity. When the buffer block 541 moves during the collision, it drives the connecting frame 5441 to move, and the movement of the connecting frame 5441 drives the pressure rod 5442 to move, and the movement of the pressure rod 5442 drives the pressure rod 5442 to move. The force wheel 5443 rolls on the distance adjusting block 5453. When the squeegee assembly is hit strongly, the buffer block 541 is displaced greatly. At this time, the pressure wheel 5443 contacts the inclined surface of the distance adjusting block 5453, which squeezes the pressure wheel 5443. As a result, the pressure rod 5442 slides in the inner cavity of the connecting frame 5441, driving the slider 5445 to slide in the inner cavity of the connecting frame 5441 and squeezing the fifth spring 5444. The sliding of the slider 5445 drives the slider 5445 to squeeze the button 5446, causing the alarm 5447 to sound an alarm, reminding the staff that the squeegee assembly has been hit strongly. Attention should be paid to the impact, and the equipment can be checked. By rotating the third threaded rod 5452 to make the distance adjusting block 5453 slide on the adjustment frame 5451, the distance between the two distance adjusting blocks 5453 is adjusted, so that the buffer block 541 can be adjusted to produce squeezing on the inclined surface of the pressure wheel 5443 and the distance adjusting block 5453 under different shaking and floating conditions, so that the alarm distance can be adjusted according to needs, thereby improving the anti-collision effect of the squeegee assembly, reducing the damage to the squeegee assembly when colliding with an obstacle, reducing the impact of the floor scrubber during the collision, that is, reducing the turbulence of spare parts caused by the collision inside the floor scrubber.

A squeegee assembly is provided on the outer surface of the floor scrubber main body 1, and the bottom end of the conduit 4 is connected to the squeegee assembly. A vacuum pump is provided in the inner cavity of the floor scrubber main body 1, and the cleaning component 3 is driven to clean the ground through the work of the motor. The squeegee assembly generates negative pressure through the vacuum pump in the inner cavity of the floor scrubber main body 1 to form a sealed cavity with the ground. When the floor scrubber main body 1 moves forward, the sewage is quickly sucked into the sewage tank in the inner cavity of the floor scrubber main body 1 under the action of negative pressure to avoid secondary pollution caused by liquid residue.

[0040] See also Figure 1 and Figure 2 As shown, the cleaning assembly 3 includes a cleaning frame 31, the inner cavity of the cleaning frame 31 is rotatably connected to a roller brush disc 32, the roller brush disc 32 and the output end of the motor are sleeved, the outer surface of the cleaning frame 31 is connected to a first threaded bolt 33 by a thread, the bottom end of the first threaded bolt 33 is rollingly connected to a ball 34, which is mainly used to adjust the distance between the ball 34 and the ground, and a floating mechanism 35 is provided in the middle part of the upper surface of the cleaning frame 31, the upper surface of the floating mechanism 35 is fixedly connected to the lower surface of the floor scrubber body 1, and when cleaning the ground, the motor drives the roller brush disc 32 to rotate in the inner cavity of the cleaning frame 31, so that the roller brush disc 32 cleans the ground. The inclined ground causes the ball 34 to contact the ground, causing the floating mechanism 35 to tilt. The tilt of the floating mechanism 35 drives the cleaning frame 31 to tilt. The tilt of the cleaning frame 31 keeps the roller brush disc 32 in stable contact with the ground, so that the inclined ground can be cleaned evenly. The distance between the ball 34 and the ground is adjusted by rotating the position of the first threaded bolt 33 on the cleaning frame 31, and a slight gap is maintained between the ball 34 and the ground, so as not to hinder the contact between the roller brush disc 32 and the ground. At the same time, when encountering an inclined ground, the ball 34 can contact the ground, thereby driving the cleaning frame 31 to tilt, avoiding large wear of the roller brush disc 32 when cleaning the inclined ground.

[0041] See also Figure 2 and Figure 3The cam 352 is fixedly mounted on the top of the cleaning frame 31 and the cleaning frame 31 is fixedly mounted on the top of the cleaning frame 31. The cam 352 is fixedly mounted on the top of the cleaning frame 31 and the cleaning frame 31 is fixedly mounted on the top of the cleaning frame 31. The cam 352 is fixedly mounted on the top of the cleaning frame 31 and the cleaning frame 31 is fixedly mounted on the top of the cleaning frame 31. The cam 352 is fixedly mounted on the top of the cleaning frame 31 and the cleaning frame 31 is fixedly mounted on the top of the cleaning frame 31. The cam 352 is fixedly mounted on the top of the cleaning frame 31 and the cleaning frame 31 is fixedly mounted on the top of the cleaning frame 31. The spring force of the first spring 357 causes the elastic rod 358 to produce a uniform squeezing force on the floating block 351, so that the floating block 351 and the fixed block 354 remain parallel, thereby keeping the brush plate 32 parallel to the ground.

[0042] In summary, the cleaning component 3 is driven by the operation of the motor to clean the floor, and the squeegee component generates negative pressure through the vacuum pump in the inner cavity of the floor scrubber body 1 to form a sealed cavity with the floor. When the floor scrubber body 1 moves forward, the sewage is quickly sucked into the sewage tank in the inner cavity of the floor scrubber body 1 under the action of negative pressure to avoid secondary pollution caused by liquid residue. When cleaning the floor, the operation of the motor drives the roller brush plate 32 to rotate in the inner cavity of the cleaning frame 31, so that the roller brush plate 32 cleans the floor. When encountering an inclined floor, the ball 34 contacts the ground to cause the floating mechanism 35 to tilt. The tilt of the floating mechanism 35 drives the cleaning frame 31 to tilt. The tilt of the cleaning frame 31 keeps the roller brush plate 32 in stable contact with the floor, so that the inclined floor can be cleaned evenly. The bolt 33 is positioned at the cleaning frame 31 to adjust the distance between the ball 34 and the ground, maintaining a slight gap between the ball 34 and the ground, so as not to hinder the contact between the roller brush plate 32 and the ground. At the same time, when encountering an inclined ground, the ball 34 can contact the ground, thereby driving the cleaning frame 31 to tilt, avoiding large wear of the roller brush plate 32 when cleaning the inclined ground. The rubber strip mechanism 52 is used to flexibly connect with the rack 51 to facilitate better decontamination of uneven ground. The anti-collision mechanism 53 is used for side anti-collision to reduce the damage caused by the impact to the entire squeegee assembly. At the same time, the rack 51 is flexibly connected to the floor scrubber body 1 through the buffer mechanism 54 to reduce the damage caused by the impact to the entire equipment. At the same time, an alarm can be issued when a large impact occurs, so that the staff can troubleshoot the problem.
