Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and more specifically, to a vacuum cleaner floor brush with an adjustable flatness of the roller brush surface. Background Art

[0002] Vacuum cleaners are widely used cleaning tools. The working principle of a vacuum cleaner is to drive the blades to rotate at high speed by an electric motor to generate a negative air pressure inside a sealed bracket to suck dust and debris. Common vacuum cleaners include horizontal, vertical, and handheld types. Handheld vacuum cleaners are widely used because of their small size, easy carrying and use.

[0003] The roller brush is one of the main components in the vacuum cleaner floor brush. A roller brush is usually provided in the floor brush to better gather debris. Since the styles of the surfaces to be cleaned are not uniform, when cleaning on an uneven ground, the existing roller brush cannot effectively remove the debris on the ground. Summary of the Invention

[0004] The purpose of the present invention is to provide a vacuum cleaner floor brush with an adjustable flatness of the roller brush surface, which can adjust the state of the cleaning sleeve according to the style of the surface to be cleaned, so as to achieve the purpose of improving the cleaning efficiency.

[0005] To achieve the above object, the present invention provides a vacuum cleaner floor brush with an adjustable flatness of the roller brush surface, including a driving roller, a cleaning sleeve, a fixing ring, a motor, a gear and a rack. The cleaning sleeve is sleeved on the driving roller. A plurality of pulling ropes are arranged on the cleaning sleeve. The pulling ropes are arranged along the circumferential direction of the cleaning sleeve. One end of the pulling rope is connected to the fixing ring, and the fixing ring is arranged at one end of the driving roller. The other end of the pulling rope is connected to the rack, and the rack is rotatably connected to the end of the driving roller opposite to the fixing ring. The motor is arranged on the driving roller, a gear is arranged on the motor, the gear meshes with the rack, and a locking screw is arranged on the rack.

[0006] As a further description of the above technical solution:

[0007] Through holes are arranged on the cleaning sleeve. The through holes are arranged along the length direction of the cleaning sleeve, and the pulling ropes are arranged through the through holes.

[0008] As a further description of the above technical solution:

[0009] Limiting grooves are arranged on the inner surface of the cleaning sleeve. The limiting grooves are arranged along the length direction of the cleaning sleeve, and the pulling ropes are bonded in the limiting grooves.

[0010] As a further description of the above technical solution:

[0011] An installation groove is provided on the driving roller, and the gear is rotatably connected in the installation groove.

[0012] As a further description of the above technical solution:

[0013] A fixing block is provided on the side of the rack, a screw hole is provided on the fixing block, and the locking screw is inserted into the screw hole.

[0014] As a further description of the above technical solution:

[0015] A plurality of first connection through holes are provided on the fixing ring, and the first connection through holes are arranged equidistantly along the circumference of the fixing ring.

[0016] As a further description of the above technical solution:

[0017] A plurality of second connection through holes are provided on the rack, and the second connection through holes are arranged equidistantly along the circumference of the rack.

[0018] As a further description of the above technical solution:

[0019] The pulling rope is a nylon rope.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: The rotation of the motor drives the rotation of the gear, and the rotation of the gear drives the rack to rotate around the driving roller. The rack intersects with the fixing ring at the other end of the driving roller, causing the pulling rope to start to twist, so that spiral folds are formed on the surface of the cleaning sleeve, thereby adjusting the effect of the cleaning sleeve on the ground, enabling the effect to be switched at any time, with good user experience and high cleaning efficiency. Specifically, when on a flat ground, the surface of the cleaning sleeve is flat. When there are many gaps on the surface to be cleaned, spiral folds are formed on the surface of the cleaning sleeve, so that the sundries in the gaps on the surface to be cleaned can be effectively removed, thereby improving the cleaning effect of the surface to be cleaned.

[0032] Please refer to Figures 1-3, the present invention provides a vacuum cleaner floor brush with adjustable flatness on the surface of the roller brush, including a driving roller 1, a cleaning sleeve 2, a fixing ring 3, a motor 4, a gear 5 and a rack 6. The cleaning sleeve 2 is sleeved on the driving roller 1. A plurality of pulling ropes 7 are arranged on the cleaning sleeve 2. The pulling ropes 7 are arranged along the circumferential direction of the cleaning sleeve 2. One end of the pulling rope 7 is connected to the fixing ring 3. The fixing ring 3 is arranged at one end of the driving roller 1. The other end of the pulling rope 7 is connected to the rack 6. The rack 6 is rotatably connected to the end of the driving roller 1 opposite to the fixing ring 3. The motor 4 is arranged on the driving roller 1. A gear 5 is arranged on the motor 4. The gear 5 meshes with the rack 6. A locking screw 8 is arranged on the rack 6.

[0033] Through holes are arranged on the cleaning sleeve 2. The through holes are arranged along the length direction of the cleaning sleeve 2. The pulling ropes 7 are arranged in the through holes. This can make the cleaning sleeve fixed more firmly.

[0034] A limiting groove is arranged on the inner surface of the cleaning sleeve 2. The limiting groove is arranged along the length direction of the cleaning sleeve 2. The pulling ropes 7 are bonded in the limiting groove. This can facilitate the installation and replacement of the cleaning sleeve.

[0035] An installation groove is arranged on the driving roller 1. The gear 5 is rotatably connected in the installation groove. This can prevent the gear from being displaced.

[0036] A fixing block 61 is arranged on the side of the rack 6. A screw hole is arranged on the fixing block 61. The locking screw 8 is arranged in the screw hole. When the motor runs, the locking screw is loosened to facilitate the rotation of the rack. When the motor does not work, the locking screw is tightened so that the locking screw abuts against the surface of the driving roller, avoiding the relative movement between the rack and the driving roller. Thus, the locking screw holds the rack, avoiding the rotation of the rack when the driving roller rotates, and thereby improving the cleaning efficiency.

[0037] A plurality of first connection through holes are arranged on the fixing ring 3. The first connection through holes are arranged equidistantly along the circumferential direction of the fixing ring 3. A plurality of second connection through holes are arranged on the rack 6. The second connection through holes are arranged equidistantly along the circumferential direction of the rack 6. This can facilitate the installation and disassembly of the pulling ropes and facilitate the adjustment of the tightness of the pulling ropes.

[0038] The pulling rope 7 is a nylon rope.

[0039] Working principle: When the cleaning sleeve is adjusted, first open the floor brush cover, loosen the locking screw, start the motor, the gear on the motor drives the rack to rotate, so that the cleaning sleeve forms a wrinkled structure, then turn off the motor, tighten the locking screw to fix the rack, and then start the floor brush motor to make the driving roller rotate for cleaning. Since the cleaning sleeve is uneven, the dust in the gap can be taken out, thereby improving the cleaning efficiency. When the cleaning sleeve returns to its original shape, open the floor brush cover, loosen the locking screw, start the motor, let the motor rotate back, and then tighten the locking screw. Therefore, in the present invention, the rotation of the motor drives the rotation of the gear, the rotation of the gear drives the rack to rotate around the driving roller, the rack intersects with the fixed ring at the other end of the driving roller, so that the pull rope starts to twist, thus forming a spiral wrinkle on the surface of the cleaning sleeve, further adjusting the effect of the cleaning sleeve on the ground, enabling the effect to be switched at any time, with good user experience and high cleaning efficiency.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
