Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a highly integrated micro floor scrubber. Background Art

[0002] Mini floor scrubbers, a type of cleaning equipment, are widely used for floor cleaning in public places such as shopping malls, train stations, and airports due to their small size and flexible operation. However, existing mini floor scrubbers on the market lack cleaning capacity, transferability, operational flexibility, and ease of use. They struggle to achieve comprehensive functionality and sometimes lack some features.

[0003] To address the aforementioned issues with micro-floor scrubbers, the approach is typically to independently optimize and improve each functional module of the scrubber. However, this approach only involves performance improvements or structural changes to individual modules, without considering the overall structural rationality of the entire machine. Improving one module often results in a weakening of another module, complicating the overall structure of the scrubber and reducing coordination between the various functional modules, which in turn affects the overall performance of the scrubber. Furthermore, due to volume limitations, when multiple modules are improved and combined, they can easily become oversized, failing to achieve a high degree of integration and coordinated optimization between the various functional modules of the micro-floor scrubber, making it difficult for the scrubber to achieve optimal overall performance.

When working, the side of the chassis body 1 facing away from the integrated water tank assembly is the bottom side of the chassis body 1, and the integrated water tank assembly is detachably connected to the top of the chassis body 1, and the bottom side of the chassis body 1 is the working side. An empty slot 23 for inserting the cleaning assembly is provided on the side of the integrated water tank assembly close to the chassis body 1, and a lifting wheel assembly is also provided on the chassis body 1, which can lift the chassis body 1, and the lifting wheel assembly is staggered with the cleaning assembly. The lifting wheel assembly is staggered with the cleaning assembly, and a water suction assembly is connected to the side of the chassis body 1 facing away from the integrated water tank assembly, and the water suction assembly is connected to the integrated water tank assembly. Walking wheels 11 are rotatably connected on both sides of the chassis body 1.

[0043] The cleaning component is inserted into the empty slot 23 of the integrated water tank assembly. The lifting wheel assembly can save the overall equipment space after the floor scrubber is dislocated. Therefore, the floor scrubber can have cleaning ability, operational flexibility and transfer ability, and the structure of the floor scrubber is simplified, thereby ensuring the integrated setting of the modules of the floor scrubber while improving the coordination between the modules of the floor scrubber.

A one-way valve 241 is provided at the water outlet 24, and an internal water channel is provided on the chassis body 1. When the water tank body 2 is installed on the chassis body 1, the water outlet 24 is connected to the internal water channel, so that water flows automatically. When the water tank body 2 is separated from the chassis body 1, the one-way valve 241 makes the water outlet 24 sealed and watertight. The water outlet 24 and the internal water channel are close to the cleaning component. A water inlet 25 is provided on the inner wall of the second cavity 22. The water inlet 25 is close to the water absorption component and is connected to the water absorption component. A water tank cover 27 is installed at the opening of the second cavity 22.

[0045] The water tank 2 can simultaneously have the function of storing sewage and clean water, reducing the space occupied by the water tank 2 and improving space utilization. Integration can reduce the number of parts and manufacturing materials, reduce manufacturing costs, and can make full use of the space of the floor scrubber for water storage, effectively reducing the size of the floor scrubber and effectively increasing the actual usable volume of the water tank, simplifying the structure of the floor scrubber, and improving the coordination between the various modules of the floor scrubber. While draining water for cleaning, it will be accompanied by water absorption, so that the water tank 2 is always kept with water, so that the floor scrubber maintains a certain weight, thereby maintaining walking stability. The first cavity 21 can be used to store clean water and the second cavity 22 can be used to store sewage. When the user wants to clean sewage and add clean water, he only needs to pour the sewage out of the second cavity 22 and inject the clean water into the first cavity 21 through the water inlet, thereby improving operation convenience and efficiency.

[0060] Reference Figure 10 and Figure 11The cleaning assembly includes a cleaning drive member 6, a cleaning brush buckle 61 and a cleaning brush member. The cleaning drive member 6 is a motor. There are two cleaning drive members 6. The two cleaning drive members 6 are arranged in the horizontal direction. The two cleaning drive members 6 are symmetrically arranged. The cleaning drive member 6 is arranged on the side of the chassis body 1 close to the water tank body 2. A bracket 64 is installed on the cleaning drive member 6. The bracket 64 is connected to the chassis body 1 by bolts. A flexible buffer block 65 is provided on the bracket 64. The flexible buffer block 65 is located between the chassis body 1 and the bracket 6 4, it plays a supporting and shock-absorbing role. The cleaning drive member 6 is inserted into the empty slot 23 of the water tank body 2. There are two cleaning brush buckles 61. The cleaning brush buckle 61 is set at the driving end of the cleaning drive member 6. The cleaning brush buckle 61 and the cleaning drive member 6 are assembled one to one. The cleaning brush buckle 61 is located on the side of the chassis body 1 away from the water tank body 2. There are two cleaning brush members. The cleaning brush member and the cleaning brush buckle 61 are detachably connected. The cleaning brush member and the cleaning brush buckle 61 are assembled one to one, and the positions of the two cleaning brush members are close to each other.

[0061] When cleaning is required, the cleaning drive 6 drives the cleaning brush buckle 61 to rotate, driving the cleaning brush to rotate, thereby sweeping the floor, and draining the clean water in the first cavity 21 through the internal water channel of the chassis body 1 to achieve floor cleaning.

[0062] The cleaning brush assembly includes a brush disc 62 and bristles 63. In this embodiment, the total number of brush discs 62 is two, and the brush discs 62 are arranged in a horizontal direction. The brush discs 62 are installed on the cleaning brush buckle 61 by a magnet or a metal elastic buckle. In this embodiment, the brush disc 62 is sucked onto the cleaning brush buckle 61 by a magnet. At the same time, a buckle block is provided on the cleaning brush buckle 61, and the buckle block is engaged with the brush disc 62, which drives the brush disc 62 to rotate and reduce the slipping and falling of the brush disc 62. The bristles 63 are evenly distributed on the brush disc 62. The two brush discs 62 are positioned close to each other, and the two brush discs 62 are inclined to the side close to each other. The bristles 63 between the two brush discs 62 are crossed with each other. In the working state, the pressure of the bristles 63 close to each other between the two brush discs 62 on the ground is greater than the pressure of the bristles 63 of the two brush discs 62 away from each other on the ground.

[0063] During operation, the cleaning brush buckle 61 drives the brush disc 62 to rotate, so that the bristles 63 sweep the ground. At the same time, due to the inclination of the brush disc 62, the pressure of the bristles 63 in the middle of the bottom of the floor scrubber on the ground is greater than the pressure on the two sides of the bottom of the floor scrubber. Therefore, the two brush discs 62 can be rotated in opposite directions toward the middle position, thereby driving the floor scrubber to move forward, realizing the effect of automatic forward movement of the floor scrubber, reducing the need for manpower to push forward. The staff only needs to control the forward direction, and there is no need to add a structure to drive the walking wheel 11 to rotate, which is convenient for the staff to work.

[0064] Reference Figure 1 and Figure 12The lifting wheel assembly includes a pedal member 7, a connecting rod transmission member, a lifting shaft 71 and a steering wheel 72. A connecting seat 16 is provided on the chassis body 1. The pedal member 7 is rotatably connected to the connecting seat 16. The rotation axis of the pedal member 7 and the connecting seat 16 extends horizontally. The pedal member 7 is block-shaped, and a pedal 73 is connected to one side of the pedal member 7. The connecting rod transmission member is rotatably connected to the pedal member 7. The end of the connecting rod transmission member away from the pedal member 7 is connected to the lifting shaft 71, and the steering wheel 72 is a universal wheel. The steering wheel 72 is rotatably connected to the bottom end of the lifting shaft 71. The steering wheel 72 is located on the side of the chassis body 1 away from the water tank body 2. The steering wheel 72 can rotate around the axis of the lifting shaft 71 as a whole. The pedal member 7 and the connecting rod transmission member are used to drive the lifting shaft 71 to move up and down. The lifting of the lifting shaft 71 can make the steering wheel 72 close to or away from the chassis body 1.

[0065] When cleaning is required, the foot pedal 7 can be rotated to drive the lifting shaft 71 to rise through the connecting rod transmission part, so that the bristles 63 of the brush plate 62 are in contact with the ground, thereby starting the cleaning drive part 6 to drive the cleaning brush buckle 61 to rotate for cleaning. When cleaning is completed or the floor scrubber needs to change locations, the foot pedal 7 is rotated in the opposite direction to drive the lifting shaft 71 to descend through the connecting rod transmission part, so that the steering wheel 72 is away from the chassis body 1, thereby lifting the chassis body 1 and making the bristles 63 of the brush plate 62 away from the ground. At this time, only the steering wheel 72 and the walking wheel 11 are in contact with the ground, so that the position of the entire machine can be transferred by pushing or dragging it manually.

[0066] The connecting rod transmission member includes a lifting connecting rod 74, a lifting connecting plate 75, a lifting transmission shaft 76 and a first connecting rod frame 77. The lifting connecting rod 74 is staggered with the cleaning drive member 6. One end of the lifting connecting rod 74 is rotatably connected to the side of the foot pedal 7 away from the pedal 73. One end of the lifting connecting plate 75 is rotatably connected to the end of the lifting connecting rod 74 away from the foot pedal 7. The rotation axes of the rotating points at both ends of the lifting connecting rod 74 are parallel to the rotation axes of the foot pedal 7 and the connecting seat 16. The connection point of the lifting connecting rod 74 and the foot pedal 7 is staggered from the connection point of the foot pedal 7 and the connecting seat 16. The lifting transmission shaft 76 is rotatably connected to the chassis body 1. The extension direction of the lifting transmission shaft 76 is parallel to the foot pedal 7 and the connecting seat 1 6, the rotation axis of the lifting transmission shaft 76 itself is parallel to the extension direction of the lifting transmission shaft 76, one end of the lifting transmission shaft 76 is fixedly connected to the end of the lifting connecting plate 75 away from the lifting link 74, and the other end is fixedly connected to the first connecting rod frame 77, the end of the first connecting rod frame 77 away from the chassis body 1 is rotatably connected to the lifting shaft 71, the rotation axis of the first connecting rod frame 77 and the chassis body 1 is parallel to the rotation axis of the foot pedal 7 and the connecting seat 16, the first connecting rod frame 77 is rotatably connected to the chassis body 1, the rotation axis of the first connecting rod frame 77 and the chassis body 1 coincides with the rotation axis of the lifting transmission shaft 76 itself, and the first connecting rod frame 77 can drive the lifting shaft 71 to move up and down by rotation.

[0067] The lifting link 74 pushes the lifting connecting plate 75 away from the foot pedal 7, and the first connecting rod frame 77 is rotated downward by the lifting transmission shaft 76, so that the lifting shaft 71 drops and the steering wheel 72 moves away from the chassis body 1 and then contacts the ground, thereby lifting the chassis body 1 so that the bristles 63 of the brush disc 62 are away from the ground and switching to the transition mode.

[0068] The second link frame 78 is rotatably connected to one side of the chassis body 1 close to the first link frame 77 . The end of the second link frame 78 away from the chassis body 1 is rotatably connected to the lifting shaft 71 . The second link frame 78 is parallel to the first link frame 77 .

[0069] The first connecting rod frame 77, the second connecting rod frame 78, the lifting shaft 71 and the chassis body 1 can form a parallelogram structure. When the first connecting rod frame 77 rotates, the second connecting rod frame 78 rotates synchronously, so that the direction of the lifting shaft 71 remains unchanged during the lifting process, thereby maintaining the stability of the floor scrubber.

[0070] The implementation principle of a highly integrated micro floor scrubber according to an embodiment of the present application is as follows: the floor scrubber can be placed on the ground. When working, the cleaning drive member 6 drives the brush disc 62 and the bristles 63 to clean the ground. During the process, the clean water loaded in the first cavity 21 can flow to the ground, thereby facilitating the cleaning work. After cleaning, the sewage on the ground can be swept and scraped by the fixed rubber strip 45, and the sewage is sucked into the second cavity 22. When it is necessary to change the site, the foot pedal 7 can be rotated, the steering wheel 72 can be lowered, and the chassis body 1 can be lifted up, so that the cleaning component and the water absorption component are away from the ground, reducing the friction between the floor scrubber and the bottom surface, and facilitating the use of the transfer. The cleaning drive member 6 is inserted into the empty slot 23 of the water tank body 2. After the lifting wheel assembly is misaligned, the overall equipment space can be saved, so that the floor scrubber can have cleaning ability, operational flexibility, transfer ability, and good noise reduction ability, simplifying the structure of the floor scrubber, and the various components can also cooperate with each other to achieve better use effect, thereby ensuring the integrated setting of the various modules of the floor scrubber while improving the coordination between the various module components of the floor scrubber.

[0071] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and do not limit the scope of protection of the present application in turn. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
