Description

Technical Field

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

[0002] A sweeping machine is a type of machine that uses brushes or other methods to suck up debris from the floor and collect it into its own dustbin, thus completing the floor cleaning function. Existing walk-behind sweepers have complex structures; if the handle is too short, it's inconvenient to operate; if the handle is too long, it's 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 joints in existing sweepers are located at the connection between the handle and the body, and their low position results in a large operating radius when the handle swings up and down or left and right, making it very inconvenient to use in confined spaces. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art, so that the operating radius is small when the handle swings up and down or left and right, making it very convenient to use in a narrow space; at the same time, it can also lock the up and down swing or left and right swing of the handle; and when not in use, it occupies a small area in the retracted state, which can protect the bristles and water scraper from deformation.

[0004] This utility model discloses a novel floor scrubbing machine, comprising a first handle and a machine body. The bottom end of the first handle is movably connected to the machine body via an adapter unit. The adapter unit comprises 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 connecting seat also includes a locking device and a first handle. The locking device includes a spring seat and a top rod located within the spring seat that can move up and down. A rack is provided at the top of the top rod, which can mesh with the gear body. A return spring is provided between the top rod and the spring seat. The first handle is movably fixed to the top rod, with one end fixed to the machine body. Moving the other end of the first handle allows the top rod to move and mesh with the gear body. This adapter unit can swing up and down, and is the first adapter unit.

[0005] The aforementioned novel floor scrubber also includes a second handle, which is connected to the first handle via an adapter unit. This adapter unit is capable of swinging left and right and serves as the second adapter unit. The second adapter unit is equipped with a second handle that allows the push rod to displace and engage with the gear body.

[0006] The aforementioned novel floor scrubber has support casters fixedly installed on the top surface of the machine body.

[0007] The aforementioned novel floor scrubber has a support plate on the top or bottom side of the machine body, which, in conjunction with the support casters, allows the machine body to stand upright.

[0008] This invention divides the handle into two parts and the universal joint into two adapter units for vertical and horizontal swing. This reduces the swing radius of the handle, making it convenient to use in confined spaces. A locking device in the adapter unit allows for locking the handle during either vertical or horizontal swing. Support casters and a support plate on the body allow the machine to be folded up and stood upright, preventing pressure on the bristles and squeegee when not in use, thus preventing deformation and extending their service life.

[0016] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7The illustration shows an embodiment of this utility model. It includes a first handle 1A and a body 2. The bottom end of the first handle 1A is movably connected to the body 2 via an adapter unit 3. The body 2 is equipped with brush bristles 21 and a squeegee 22 for cleaning. The adapter unit 3 includes a connecting seat 31 fixed to the body 2 and a gear body 32 fixed to the end of the first handle 1A. The gear body 32 is rotatably connected to the connecting seat 31 via a rotating shaft 33. The connecting seat 31 also has a locking buckle device and a first handle 4. The locking buckle device includes a spring seat 311 and a handle located at... The spring seat 311 contains a vertically movable push rod 312. A rack 3121 is located at the top of the push rod 312, which meshes with the gear body 32. A return spring 313 is provided between the push rod 312 and the spring seat 311. A shift fork 314 also engages with the push rod 312. The first handle 4 is movably fixed to the body 2 and can be moved by the shift fork 314. Moving the other end of the first handle 4 causes the push rod 312 to displace and mesh with the gear body 32. The adapter unit 3, which can swing up and down, is the first adapter unit 3A. Thus, when the first handle 1A is in a suitable position, the first handle 4 can be stepped down. The first handle 4 moves the shift fork 314 to release the lock, and the push rod 312 meshes with the gear body 32 under the action of the return spring 313. At this time, the vertical swing direction (X-axis direction) of the first handle 1A is locked.

[0018] This utility model of a floor scrubber also includes a second handle 1B, which is connected to the first handle 1A via an adapter unit 3. This adapter unit 3, capable of left-right swing (Y-axis direction), is set at a 90° angle to the direction of the first adapter unit 3A. The first adapter unit 3A swings up and down (X-axis direction), while the second adapter unit 3B swings left and right (Y-axis direction). The second adapter unit 3B is equipped with a second handle 5, which can be used to move a fork to displace the push rod and engage or disengage it with the gear body, enabling swinging or locking.

[0019] Furthermore, the floor scrubber of this invention is equipped with support casters 23 fixed to the top surface of its body 2. This allows the operator to easily control the direction, moving forward or backward.

[0020] Furthermore, the floor scrubber of this invention has a support plate 24 on the top or bottom side of the machine body 2. The support plate 24 cooperates with the support casters 23 to allow the machine body 2 to be folded up and placed upright. In this state, it occupies less space and can better protect the brush bristles 21 and the squeegee 22 from deformation, thus extending the service life of the brush bristles 21 and the squeegee 22.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
