Description

Technical Field

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

[0002] With the continuous progress of society and the improvement of science and technology, mechanical intelligent cleaning life has become a social trend. A floor scrubber is a cleaning machine suitable for cleaning hard floors while sucking out sewage and taking it away from the site. It has the advantages of environmental protection, energy saving, and high efficiency.

[0003] The existing methods of controlling the working pressure of the floor washing disc of the floor washing machine are: one is to rely on the weight of the floor washing disc itself, but the disadvantage is that there is only one pressure level, which cannot adapt to different cleaning sites; the second is to rely on the weight of the floor washing disc itself, and at the same time add a mechanical pressure device (such as a gas spring, etc.) to achieve two working pressure options. The disadvantage is that the pressure device needs to be manually pressurized or released, and there are only two optional pressure levels; the third is to lift and pressurize the electric push rod, and its control method is to detect the working current of the floor washing disc to the ground to control the extension and retraction of the push rod to implement pressure changes, but the disadvantage is that the working pressure of the floor washing disc is unstable, and the working pressure will fluctuate with the changes in the smoothness and flatness of the ground, resulting in the actual working pressure being greater on the smoother and flatter the ground, and the actual working pressure being smaller on the rougher and unevener the ground, and the flexibility of adjusting the working pressure of the floor washing disc is low. Summary of the invention

[0004] In order to improve the flexibility of adjusting the working pressure of a floor scrubber, the present application provides a cleaning floor scrubber.

[0005] The present application provides a cleaning floor washing method, which adopts the following technical solution:

[0006] A cleaning floor scrubber comprises a base frame, a brush disc frame is provided on one side of the base frame, a lifting arm is rotatably connected to the base frame, a lifting drive member for driving the lifting arm to rotate is provided on the base frame, an active cavity for the lifting arm to move into is opened on the brush disc frame, the inner top wall of the active cavity is located in the swinging path of the lifting arm, a pressure member is provided on the lifting arm, the pressure member is connected to the brush disc frame, a brush disc assembly is provided on the brush disc frame, an anti-tilt lifting assembly is connected to the base frame, and the anti-tilt lifting assembly is connected to the brush disc frame.

[0007] By adopting the above technical solution, the base frame can be installed at the bottom of the floor scrubber so that the lifting arm is in contact with the inner top wall of the movable chamber. When working, the driving end of the lifting drive member is extended to make the lifting arm swing downward, and the brush disc frame presses the brush disc assembly on the ground under the action of gravity, so that the ground can be cleaned by the brush disc assembly. At this time, the working pressure on the ground is the gravity of the floor scrubber itself. When pressurization is required, the driving end of the lifting drive member continues to drive the lifting arm to swing downward, and a downward force is applied to the brush disc frame through the pressure member, thereby pressurizing the ground. When further pressurization is required, the lifting arm is continued to be driven to swing downward, and the pressure on the ground is further increased through the pressure member. Therefore, the working pressure of the floor scrubber on the ground can be flexibly adjusted according to usage requirements, thereby improving the flexibility of adjusting the working pressure.

[0008] Optionally, a sliding hole is formed on the side wall of the lifting arm, a sliding sleeve is connected to the driving end of the lifting drive member, and the sliding sleeve is slidably connected to the sliding hole.

[0009] By adopting the above technical solution, when the brush disc assembly is worn during the cleaning process, the brush disc frame drops due to gravity, the lifting arm gradually swings downward, the sliding sleeve and the sliding hole slide relative to each other, so that the brush disc assembly contacts the ground, so that the floor washing disc is still pressed on the ground with its own weight, thereby achieving working pressure compensation.

[0010] Optionally, the anti-tilt lifting assembly includes a first lifting arm and a second lifting arm, one end of the first lifting arm and one end of the second lifting arm are both rotatably connected to the side wall of the base frame, one end of the first lifting arm away from the base frame and one end of the second lifting arm away from the base frame are both rotatably connected to the side wall of the brush plate frame, and the rotation connection point of the first lifting arm and the rotation connection point of the second lifting arm form a parallelogram.

[0011] By adopting the above technical solution, the tilting of the brush plate frame during lifting and lowering can be reduced, thereby ensuring the stability of the working angle of the brush plate assembly.

[0012] Optionally, the pressure member includes a pressure spring, one end of which is connected to the lifting arm, and the other end of which is connected to the top of the brush plate frame.

[0013] By adopting the above technical solution, when the lifting arm swings downward, a downward force is applied to the brush plate frame through the pressure spring, thereby pressurizing the ground.

[0014] Optionally, a protective baffle is provided on the side wall of the brush plate frame, and a protective baffle pad is clamped on the side wall of the protective baffle.

[0015] By adopting the above technical solution, the brush plate frame can be less likely to be damaged.

[0016] Optionally, the side wall of the brush plate frame is rotatably connected to a connecting rod, the number of the connecting rods is at least two, and the protective baffle frame is connected to the connecting rod.

[0017] By adopting the above technical solution, when passing through a raised terrain, the protective baffle frame collides with the raised terrain and then moves upward under the action of the connecting rod, thereby reducing the situation of being stuck by the ground.

[0018] Optionally, the brush plate assembly includes a brush plate driving member and a movable brush plate, the brush plate driving member is arranged on the brush plate frame, the movable brush plate is arranged at the bottom of the brush plate frame, and the brush plate driving member can be used to drive the movable brush plate to rotate.

[0019] By adopting the above technical solution, after the brush disc frame is lowered, the brush disc driving member can drive the movable brush disc to rotate, thereby cleaning the floor.

[0020] Optionally, a driving end of the brush disc driving member is connected to a mounting frame, and a brush buckle is provided on the movable brush disc, and the brush buckle is snap-connected with the mounting frame.

[0021] By adopting the above technical solution, the convenience of disassembling and assembling the movable brush plate is improved.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The base frame can be installed at the bottom of the floor scrubber so that the lifting arm abuts against the inner top wall of the active chamber. When working, the driving end of the lifting driving member extends to swing the lifting arm downward. The brush disc frame presses the brush disc assembly on the ground under the action of gravity, so that the ground can be cleaned by the brush disc assembly. At this time, the working pressure on the ground is the gravity of the floor scrubber itself. When pressure is required, the driving end of the lifting driving member continues to drive the lifting arm to swing downward, and a downward force is applied to the brush disc frame through the pressure member, thereby pressurizing the ground. When further pressure is required, the lifting arm continues to swing downward, and the pressure on the ground is further increased through the pressure member. Therefore, the working pressure of the floor scrubber on the ground can be flexibly adjusted according to the use requirements, thereby improving the flexibility of adjusting the working pressure;

[0024] 2. When the brush disc assembly is worn during the cleaning process, the brush disc frame drops due to gravity, the lifting arm gradually swings downward, the sliding sleeve and the sliding hole slide relative to each other, so that the brush disc assembly contacts the ground, so that the floor scrubber is still pressed on the ground with its own weight, thereby achieving working pressure compensation;

[0025] 3. When the lifting arm swings downward, a downward force is applied to the brush plate frame through the pressure spring, thereby pressurizing the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The embodiment of the present application discloses a cleaning dishwashing machine.

[0036] Reference Figure 1 and Figure 2A floor cleaning dish, comprising a base frame 1, a brush plate frame 8 is provided on one side of the base frame 1, the brush plate frame 8 comprises a top frame part and a bottom frame part, the top frame part is fixed to the top of the bottom frame part, the side wall of the base frame 1 is rotatably connected with a lifting arm 6, the rotation axis of the lifting arm 6 extends in the horizontal direction, the lifting arm 6 can swing around the connection point between the base frame 1 and the lifting arm 6, the side wall of the base frame 1 is rotatably connected with a lifting drive member 2 for driving the lifting arm 6 to rotate, the lifting drive member 2 is an electric push rod, the lifting drive member 2 is located above the lifting arm 6, and the side wall of the top frame part of the brush plate frame 8 is provided with a lifting drive member 2 for driving the lifting arm 6 to rotate. An active cavity 81 is provided for the lifting arm 6 to move into, and the lifting arm 6 can swing in the active cavity 81. The inner top wall of the active cavity 81 is located in the swinging path of the lifting arm 6. The top side of the end of the lifting arm 6 away from the base frame 1 can abut against the inner top wall of the active cavity 81 by swinging. A pressure piece is provided on the lifting arm 6, and the end of the pressure piece away from the lifting arm 6 is connected to the top frame part of the brush disc frame 8. The bottom plate part of the brush disc frame 8 is provided with a brush disc assembly. The side wall of the base frame 1 is connected to an anti-tilt lifting assembly. The end of the anti-tilt lifting assembly away from the base frame 1 is connected to the top frame part of the brush disc frame 8.

[0037] The base frame 1 can be installed at the bottom of the floor scrubber for use. In the standby state, the lifting arm 6 abuts against the inner top wall of the active chamber 81. When work is required, the driving end of the lifting drive member 2 can be extended to make the lifting arm 6 swing downward. At the same time, the brush disc frame 8 moves downward under the action of gravity, so that the brush disc assembly contacts the ground, so that the ground is cleaned by the brush disc assembly. At this time, the pressure of the brush disc assembly on the ground is the gravity of the floor scrubber itself. The working pressure at this time is the first gear working pressure. When the pressure on the ground needs to be increased, the driving end of the lifting drive member 2 can be further extended to make the lifting arm 6 swing downward away from the active chamber 81. The inner top wall applies a downward force to the brush disc frame 8 through the pressure-applying member, thereby increasing the pressure of the brush disc assembly on the ground, thereby reaching the second-level working pressure. When the pressure needs to be further increased, the driving end of the lifting drive member 2 can continue to extend, and the lifting arm 6 can continue to swing downward, and a greater force can be applied through the pressure-applying member. When the lifting arm 6 reaches the maximum swing angle, it can be pressed downward on the top side of the bottom plate of the brush disc frame 8, which can further increase the downward force applied to the brush disc frame 8, thereby reaching the third-level working pressure, so that the working pressure of the floor scrubber on the ground can be changed according to different usage requirements, and the adjustment flexibility is high.

[0038] When the work is finished or the scrubbing pan is to be raised, the driving end of the lifting drive member 2 is gradually retracted, and the lifting arm 6 gradually swings upward under the action of the lifting drive member 2. The lifting arm 6 swings upward, and the top side of the end of the lifting arm 6 away from the base frame 1 contacts the inner top wall of the movable cavity 81. At this time, the lifting arm 6 lifts the brush plate frame 8 upward through the inner top wall of the movable cavity 81, thereby lifting the scrubbing pan off the ground and reducing the driving resistance of the scrubber.

[0039] Reference Figure 2 and Figure 3 A sliding hole 61 is provided on the side wall of the lifting arm 6, and the sliding hole 61 is a waist-shaped hole. A sliding sleeve 21 is connected to the driving end of the lifting drive member 2, and the sliding sleeve 21 is slidingly connected to the sliding hole 61. The sliding sleeve 21 is installed on the telescopic rod of the lifting drive member 2 through bolts and nuts, and the bolts and nuts restrict the sliding sleeve 21 in the sliding hole 61.

[0040] When working under the first-gear working pressure, the driving end of the lifting drive member 2 is extended, and the sliding sleeve 21 slides to the side of the sliding hole 61 away from the base frame 1. When the brush plate assembly is worn during cleaning the floor, the brush plate frame 8 gradually descends under the action of gravity. At this time, the inner top wall of the movable cavity 81 exerts downward pressure on the lifting arm 6, causing the lifting arm 6 to gradually swing downward, causing the sliding sleeve 21 to gradually move to the side of the sliding hole 61 close to the base frame 1, so that the floor washing plate is still pressed on the ground with its own weight, thereby achieving working pressure compensation, so that the first-gear working pressure of the floor washing plate can be roughly maintained at its own weight, ensuring that the first-gear working pressure is constant, and when the sliding sleeve 21 is abutted against the side wall of the sliding hole 61 close to the base frame 1, it indicates that the maximum compensation state has been reached, and the brush plate assembly needs to be replaced.

[0041] Reference Figure 2 and Figure 4 The anti-tilt lifting assembly includes a first lifting arm 3 and a second lifting arm 5, one end of the first lifting arm 3 and one end of the second lifting arm 5 are both rotatably connected to the side wall of the base frame 1, one end of the first lifting arm 3 away from the base frame 1 and one end of the second lifting arm 5 away from the base frame 1 are both rotatably connected to the side wall of the top frame of the brush plate frame 8, the extension direction of the rotation axis of the rotation connection point of the first lifting arm 3 and the extension direction of the rotation axis of the rotation connection point of the second lifting arm 5 are both parallel to the extension direction of the rotation axis of the lifting arm 6, the two rotation connection points of the first lifting arm 3 and the two rotation connection points of the second lifting arm 5 form a parallelogram, which can reduce the tilt of the brush plate frame 8 during lifting and lowering, and ensure that the working angle of the brush plate assembly remains unchanged.

[0042] Reference Figure 2 and Figure 3 The pressure-applying member includes a pressure spring 4, one end of the pressure spring 4 is connected to the end of the lifting arm 6 away from the base frame 1, and the other end is connected to the top of the top frame of the brush disc frame 8. When switching the second-level working pressure and the third-level working pressure, the lifting arm 6 swings downward to extend the pressure spring 4, and the pressure spring 4 can apply a downward pulling force to the brush disc frame 8, thereby increasing the force on the ground.

[0043] Reference Figure 1 and Figure 5The side wall of the brush disc frame 8 is provided with a protective guard frame 82, and the side wall of the protective guard frame 82 is connected with a clamping clip 83. The protective guard frame 82 is provided with a protective guard pad 84 through the clamping clip 83. The protective guard frame 82 and the protective guard pad 84 can provide protection for the chassis of the brush disc frame 8 and reduce the situation where the brush disc frame 8 is damaged.

[0044] The side wall of the chassis of the brush disc frame 8 is rotatably connected to a connecting rod 85, and the number of connecting rods 85 is at least two. The connecting rods 85 are parallel to each other, and the protective guard frame 82 is rotatably connected to the connecting rod 85 away from the brush disc frame 8. The bottom of the protective guard frame 82 is rotatably connected to a roller. When the floor washing disc passes through a raised terrain, the ground can push the bottom of the protective guard frame 82 and the protective guard pad 84 upward, so that the protective guard frame 82 and the protective guard pad 84 move upward, so that the floor washing machine can pass through the raised terrain smoothly, reduce the situation where the floor washing disc is stuck by the ground, and reduce the damage to the protective guard frame 82.

[0045] Reference Figure 1 and Figure 6 The brush plate assembly includes a brush plate driving member 71 and a movable brush plate 7. The brush plate driving member 71 is a motor. The brush plate driving member 71 is arranged on the top of the chassis of the brush plate frame 8. The movable brush plate 7 is arranged at the bottom of the brush plate frame 8. Bristles are arranged at the bottom of the movable brush plate 7. The brush plate driving member 71 can be used to drive the movable brush plate 7 to rotate. The driving end of the brush plate driving member 71 is connected to the movable brush plate 7.

[0046] After the brush plate frame 8 is lowered, the bristles at the bottom of the movable brush plate 7 contact the ground, so that the brush plate driving member 71 drives the movable brush plate 7 to rotate, and the ground can be cleaned. When the bristles at the bottom of the movable brush plate 7 are worn, pressure compensation is performed through the sliding sleeve 21 and the sliding hole 61.

[0047] The driving end of the brush plate driving member 71 is connected to a mounting bracket 72, and the mounting bracket 72 is rotatably connected to the bottom of the chassis of the brush plate frame 8. A brush buckle 73 is installed on the top of the movable brush plate 7, and the brush buckle 73 is snap-connected with the bottom of the mounting bracket 72. The snap-connection method can make the movable brush plate 7 easier to assemble and disassemble, thereby improving the convenience of disassembly and assembly of the movable brush plate 7.

[0048] The implementation principle of a cleaning floor scrubber according to an embodiment of the present application is as follows: when the floor scrubber is working, the driving end of the lifting driving member 2 is extended to cause the lifting arm 6 to swing downward, and the brush disc frame 8 presses the movable brush disc 7 against the ground under the action of gravity, so that the ground can be cleaned by the movable brush disc 7. At this time, the pressure of the floor scrubber on the ground is the gravity of the floor scrubber itself. When pressure is required, the driving end of the lifting driving member 2 continues to drive the lifting arm 6 to swing downward, and a downward force is applied to the brush disc frame 8 through the pressure spring 4, thereby pressurizing the ground. When further pressure is required, the lifting arm 6 continues to be driven to swing downward to further increase the pressure on the ground. When the lifting arm 6 reaches the maximum downward swing distance, the lifting arm 6 can be pressed on the top side of the chassis of the brush disc frame 8 to achieve the effect of further pressurization.

[0049] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
