Description

Technical Field

[0001] This utility model relates to a floor cleaning device, and more particularly to a hand-held floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning tool suitable for hard floors that uses brushes to scrub the floor while simultaneously removing wastewater from the site. Existing walk-behind floor scrubbers have complex structures; a short handle makes operation inconvenient, while a long handle makes it difficult to clean corners or areas under tables and chairs. To address this, universal joints are installed at the connection between the handle and the body to allow for handle adjustment and facilitate cleaning. However, the universal joint on existing floor scrubbers is located at the connection between the handle and the body, and its low position results in a large operating radius when the handle swings up and down or left and right, which is very inconvenient when used in confined spaces. Furthermore, when not in use and idle, the handle and body cannot be properly stored, taking up considerable space and making placement difficult. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. By improving the handle, the operating radius is smaller when the handle swings up and down or left and right, making it very convenient to use in narrow spaces. At the same time, part of the handle can be attached to the body, so that it occupies less space when not in use and can protect the bristles and water scraper from deformation.

[0004] This utility model discloses a floor scrubbing machine, comprising a machine body and an operating handle connected to the machine body. The operating handle includes a handle rod and an operating handle panel. The machine body includes a disc-shaped brush device for scrubbing the floor, a clean water tank and clean water pipeline for supplying clean water to the brush device, a squeegee for collecting wastewater and a wastewater pipeline for sucking wastewater into the wastewater tank, a first motor for powering the brush device, a vacuum pump for absorbing wastewater, and a battery for powering the first motor and the vacuum pump. The vacuum pump is connected to the wastewater pipeline. The machine body also includes support wheels for movement. The clean water tank is located at the bottom near the brush device. The wastewater tank is located above the clean water tank. The handle is characterized by comprising a first handle and a second handle. The first handle has a bent portion. A mounting groove is provided in the machine body, and a machine body fixing seat is provided in the mounting groove. The bottom end of the first handle is movably connected to the machine body fixing seat via a first adapter unit that swings up and down. The upper end of the first handle is connected to the second handle via a second adapter unit that swings left and right. The adapter unit includes a connecting seat fixed to the machine body and a gear body fixed to the end of the first handle. The gear body is rotatably connected to the connecting seat via a rotating shaft. The bent portion of the first handle and the second handle can conform to the outer surface of the wastewater tank.

[0005] The aforementioned floor scrubbing machine also has a locking device on the outer surface of the wastewater tank for fixing the second handle.

[0006] In the aforementioned floor scrubber, the support wheel is located at the lower left and extends outwards, and a rubber pad is also provided on the left side of the machine body. The rubber pad and the support wheel constitute the support foot of the floor scrubber when it is idle.

[0007] In the aforementioned floor scrubbing machine, the bottom edge of the squeegee is close to the ground, and the squeegee, the bottom surface of the machine body, and the ground form a sealed space, with the wastewater pipe connected to this sealed space.

[0008] This invention divides the handle into two parts, with the first handle having a bent section that fits snugly against the machine body. In the non-working state, it occupies a small area and protects the bristles and squeegee from deformation. Support casters and rubber pads on the machine body allow it to be folded up and placed upright, ensuring the bristles and squeegee are not subjected to pressure when not in use, thus preventing deformation and extending their service life.
