Description

Technical Field

[0001] The present application relates to the technical field of floor scrubbers, and in particular to an adaptive water suction rake connection structure. Background Art

[0002] A floor scrubber is a device used to clean hard floors, such as tiles, marble, concrete, etc. It usually consists of one or more rotating brushes, a water suction system, a detergent spraying device, and a drive system. A floor scrubber can greatly improve cleaning efficiency, reduce labor intensity, and keep the floor clean and tidy. A floor scrubber usually consists of the following main components:

[0003] Chassis;

[0004] Brush disc / brush head: The brush disc or brush head of the floor scrubber is the part used to clean the floor. They are usually made of wear-resistant materials such as nylon or bristles, and are driven to rotate by an electric motor.

[0005] Suction rake: The suction rake is another important part of the floor scrubber, used to suck water and dirt from the cleaned floor into the machine's wastewater tank.

[0006] Water tank: A floor scrubber usually has a water tank to store water or detergent for cleaning.

[0007] Wastewater tank: The wastewater tank is used to collect wastewater and dirt absorbed by the floor scrubber.

[0008] Electric motor: The electric motor of the floor scrubber is used to drive the brush plate / brush head to rotate and the water suction rake to work.

[0009] Control panel: Floor scrubbers are usually equipped with a control panel to adjust and control the machine's operating parameters, such as brush disc / brush head speed, suction rake pressure, etc.

[0010] Wherein, the water suction rake is composed of two parts: the water suction rake and the connecting component connected to the rake body. It is an important component that connects, undertakes and supports the rake body to complete the water suction action.

[0011] Working principle: the inner cavity of the rake is connected to the sewage suction pipe, a certain vacuum degree is generated in the cavity, and the vacuum inner cavity completes the sewage suction work on the ground with sewage through the scraper strip.

[0012] According to the requirements of the terrain and the various conditions of the machine, the rake body needs to be connected with the components to provide support for multiple spatial position changes. That is, when working, the rake body descends to touch the ground, and when stopping the work, the rake body needs to leave the ground at a certain height to prevent the rake body from scraping the ground and avoiding obstacles.

[0013] The lifting and lowering of the rake body is usually achieved by using a swing rod that swings up and down, with one end of the swing rod fixed on the horizontal axis and the other end connected to the fixed rake body; the lifting and lowering of the rake body is achieved by controlling the swing of the swing rod through a motor. Since the rake body is fixed at the end of the swing rod, the rake body will swing with the swing rod during lifting and lowering, and the angle of the rake body (front and back tilt) will change; because the rubber strip of the water-absorbing rake must maintain a certain angle with the ground to achieve the best water absorption effect; and the above-mentioned swinging method makes the angle between the rubber strip of the water-absorbing rake and the ground too large, resulting in a reduced water absorption effect of the rake body, and it is impossible to completely remove stains and water stains on the ground, resulting in a poor cleaning effect. Utility Model Content

[0027] One end of the second connecting component is rotatably connected to the rotating shaft, and the other end is hinged to the connecting assembly.

[0028] By adopting the above technical solution, one end of the first connecting component is welded to the second connecting component to form an integral body, so that the driving assembly and the connecting assembly can indirectly rotate around the rotating shaft, thereby supporting the rake body supporting component connected to the second welding assembly to swing stably left and right.

[0029] Optionally, the connection component includes:

[0039] An elastic component, one end of which is hinged to the central axis, and the other end of which is hinged to the swing angle component;

[0040] At least two groups of elastic components are provided, and the elastic components are arranged in parallel.

[0041] By adopting the above technical scheme, the limiting part of the central axis limits the swing angle of the parallelogram linkage, so that when the parallelogram linkage swings, it does not contact the second connecting part, thereby reducing the wear of the parallelogram linkage; the limiting part of the central axis limits the swing angle of the swing angle component, and the elastic component applies a reaction force to the central axis, so that when the driving assembly drives the swing angle component to swing up and down, the rake body supporting component can still remain horizontal, thereby reducing the angle between the rubber strip of the water-absorbing rake and the ground, thereby improving the cleaning effect.

[0042] Optionally, an angle adjustment component is provided on one end of the elevation component away from the hinged end of the swing component, one end of the angle adjustment component is connected to the elevation component, and the other end is hinged to the swing component;

[0045] One end of the guide component is inserted into the swing angle component and is slidably connected with the swing angle component.

[0046] By adopting the above technical solution, an angle adjustment component is provided to cope with the problem that due to tolerance reasons of parts during the production and assembly process, the water suction rake may not be at the required ideal elevation angle in the initial assembled state. By providing the angle adjustment component, the elevation angle of the water suction rake can be adjusted, and by providing the guide component, the movement of the elevation component can be guided, and the stable rotation of the rake body support component can be supported.

[0047] Optionally, the angle adjustment component includes:

[0048] An adjusting screw, one end of which is hinged to the swing angle component, and the other end of which is passed through the elevation angle component and is slidably connected to the elevation angle component;

[0052] By adopting the above technical scheme, when it is necessary to reduce the angle between the water suction rake and the horizontal ground, the second fixed block is rotated to move away from the first fixed block, and then the first fixed block is rotated, the first fixed block pushes the end of the elevation angle component that is not hinged to the standard swing angle component close to the swing angle component, and the angle between the rake body support component and the horizontal ground gradually decreases, that is, the angle between the water suction rake and the horizontal ground gradually decreases until the first fixed block pushes the elevation angle component to press against the second fixed block, and the adjustment is completed; similarly, when it is necessary to increase the angle between the water suction rake and the horizontal ground, the first fixed block is first rotated to move away from the elevation angle component, and then the second fixed block is rotated, the second fixed block pushes the elevation angle component close to the first fixed block, until the elevation angle component presses against the first fixed block, and the adjustment is completed, and the angle between the water suction rake and the horizontal ground increases; the above scheme can stably adjust the elevation angle of the water suction rake, so as to deal with the fact that the water suction rake is not necessarily at the required ideal elevation angle in the initial state of assembly due to tolerance reasons of parts during the production and assembly process, and the elevation angle of the water suction rake can be adjusted by setting an angle adjustment component.

[0054] By adopting the above technical solution, the vacuum degree of the rake body of the water suction rake will change during operation, and the rubber strip of the rake body should maintain a fixed pressure on the ground during operation, so an excess pressure will be added in the design, part of which acts on the rubber strip. If the excess pressure is not dispersed, it is easy to cause damage to the rubber strip. The universal wheel can bear the pressure, achieve stable application of pressure and protect the rubber strip. At the same time, considering that the machine needs to turn, the water suction rake swings left and right on the horizontal plane when turning, and the universal wheel can just balance or solve this problem, so that the rake body of the floor scrubber can operate stably.

[0055] In summary, this application has at least the following beneficial effects:

[0056] 1. When operation is required, the driving assembly drives the second welding assembly to rotate, and the second welding assembly drives the rake body supporting component to swing, the water suction rake contacts the ground, and the driving assembly stops working; the two ends of the driving assembly are respectively connected to the first welding assembly and the second welding assembly, and the rake body supporting component is connected to the second rake body supporting component. When the driving assembly drives the second welding assembly to swing, the angle (front and back tilt) change of the rake body supporting component is reduced, thereby improving the problem that the angle offset between the rubber strip of the existing water suction rake and the ground is too large, resulting in a decrease in the water absorption effect of the rake body; in addition, during the movement, when the water suction rake encounters an obstacle, the first welding assembly swings left and right around the rotating shaft, so that the extrusion force between the water suction rake and the obstacle is reduced, thereby protecting the water suction rake and extending its service life.

[0057] 2. By setting up a parallel four-link, the parallel four-link has the ability to adjust the angle without changing the length, providing good stability, and being able to absorb and disperse the impact force fed back by the suction rake during operation, thereby protecting the suction rake.

[0058] 3. By setting the swing angle component, the elevation component, the first connecting component, the second connecting component and the parallel four-link, the components cooperate with each other and can stably swing left and right around the rotation axis. When the driving component drives the rake body support component to swing at an elevation angle, the rake body support component can maintain a certain horizontality, so that the angle between the rubber strip of the water-absorbing rake and the ground is reduced.

[0059] 4. The limit part of the central axis limits the swing angle of the parallelogram linkage so that the parallelogram linkage does not come into contact with the second connecting part when it swings, thereby reducing the wear of the parallelogram linkage; the limit part of the central axis limits the swing angle of the swing angle component, and the elastic component applies a reaction force to the central axis, so that when the driving assembly drives the swing angle component to swing up and down, the rake body supporting component can still remain horizontal, thereby reducing the angle between the rubber strip of the water-absorbing rake and the ground, thereby improving the cleaning effect.

[0060] 5. The angle adjustment component is provided to cope with the fact that due to tolerance reasons during the production and assembly process of parts, the water suction rake may not be at the required ideal elevation angle in the initial assembled state. By providing the angle adjustment component, the elevation angle of the water suction rake can be adjusted, and by providing the guide component, the movement of the elevation component can be guided, and the stable rotation of the support component of the rake body can be supported.

[0061] 6. The vacuum degree of the rake body of the water suction rake will change during operation, and the rubber strip of the rake body should maintain a fixed pressure on the ground during operation. Therefore, an excess pressure will be added in the design, part of which acts on the rubber strip. If the excess pressure is not dispersed, it will easily cause damage to the rubber strip. The universal wheel can bear the pressure, achieve stable application of pressure and protect the rubber strip. At the same time, considering that the machine needs to turn, the water suction rake swings left and right on the horizontal plane when turning, and the universal wheel can just balance or solve this problem, so that the rake body of the floor scrubber can operate stably.
