Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a water squeezing roller and structure for a floor mopping machine. Background Art

[0002] The water squeezing roller is a component in a floor mopping machine and a cleaning machine, and is generally used to separate sewage from a water absorbing material. Specifically, it rotates synchronously with a rotating roller attached with a water absorbing material, and squeezes the water absorbing material to make the sewage fall off the water absorbing material.

[0003] For example, a self-cleaning floor sweeping and mopping all-in-one machine disclosed in Chinese Patent Application Publication No. CN208301596U, which was published on January 1, 2019, includes a machine body, a drive system, a floor sweeping mechanism, a floor mopping mechanism and wheels; the machine body includes a housing and a hand push rod installed at the rear side of the housing; the drive system includes a servo motor, a belt pulley, a transmission belt and a cross transmission belt; the floor sweeping mechanism is placed at the front end of the machine body and includes a brush roller and a dustbin. A belt pulley is provided on the brush roller and is connected to the servo motor through a transmission belt. The dustbin is installed at the rear side of the brush roller and is provided with a handle and can be pulled out from one side of the housing; the floor mopping mechanism is placed behind the floor sweeping mechanism and includes a water spraying device, a cotton swab roller and a water squeezing device. A belt pulley is provided on the cotton swab roller and is connected to the servo motor through a cross transmission belt. The water spraying device is installed above the cotton swab roller, and the water squeezing device is installed at the rear side of the cotton swab roller; the wheels are installed at the bottom end of the machine body. It is proposed in its specification that when the cotton swab roller rotates, it will also drive the rotation of the hard roller, and the hard roller will exert a squeezing force on the cotton swab, thereby squeezing out the sewage absorbed from the ground and flowing it into the sewage tank through a drainage plate for unified treatment.

[0004] It can be seen that in the prior art, a drainage plate is required to guide the sewage into the sewage tank. The design of the drainage plate requires additional installation space and installation procedures, and it is not easy to lead out the sewage. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is as follows:

[0006] First, to provide a water squeezing roller and structure, by arranging a filter screen on the water squeezing roller and cooperating with a diversion groove, the squeezed sewage can be smoothly introduced into a sewage collection device, improving the cleaning effect, reducing the manufacturing cost and reducing the manufacturing process.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A water squeezing roller structure for a floor mopping machine, comprising a frame, a water squeezing roller, a mopping roller, a clean water washing device and a sewage recycling device. The water squeezing roller and the mopping roller are both rotatably connected to the frame. The mopping roller is driven by a motor. The position of the clean water washing device corresponds to the position of the mopping roller, and the position of the sewage recycling device corresponds to the position of the water squeezing roller. A plurality of diversion grooves are provided on the water squeezing roller, and the diversion grooves are spirally distributed on the water squeezing roller.

[0008] Preferably, a filter screen is wrapped outside the water squeezing roller.

[0009] In this design, through the design of the spiral diversion grooves on the water squeezing roller, the sewage is converged in the diversion grooves and guided to a designated position, and then concentrated and dropped into the sewage tank of the sewage recycling device. Compared with the prior art where the sewage tank needs to cover the entire area below the water squeezing roller and the contact part between the mopping roller and the water squeezing roller, the sewage tank in this design only needs to cover a part of the area below the water squeezing roller.

[0010] In the above solution, the mopping roller is driven by a motor, and the water squeezing roller is driven to rotate by the friction belt between it and the mopping roller.

[0011] Preferably, the diversion grooves on the water squeezing roller are designed in sections, forming V-shaped grooves on the basis of the spiral distribution.

[0012] Optionally, an adjusting mechanism is further provided on the frame. One end of the adjusting mechanism for adjusting the relative distance between the water squeezing roller and the mopping roller is connected to the water squeezing roller, and the other end of the adjusting mechanism is fixedly connected to the frame.

[0013] Optionally, the adjusting mechanism includes a sliding plate and an adjusting device. The sliding plate is connected to both ends of the water squeezing roller, and the sliding plate is slidably connected to the frame. The fixed end of the adjusting device is fixedly connected to the frame, and the movable end of the adjusting device is fixedly connected to the sliding plate.

[0014] Optionally, the mopping roller is a hollow circular tube.

[0015] Optionally, a plurality of water absorption cloths are wrapped outside the mopping roller.

[0016] Optionally, the water absorption cloth is a long fiber strip cloth.

[0017] Optionally, there can be two or more pairs of combinations of the water squeezing roller and the mopping roller, and the motor drives the mopping roller through a belt.

[0018] The beneficial technical effects of the present utility model are as follows: Through the design of the spiral diversion grooves on the water squeezing roller, sewage is converged in the diversion grooves and guided to a specified position, and then concentrated and dropped into the sewage tank of the sewage recycling device.

The sliding plate 6 is slidably connected to the frame 1. The fixed end of the adjusting device 7 is fixedly connected to the frame 1, and the movable end of the adjusting device 7 is fixedly connected to the sliding plate 6.

[0028] The mopping roller 3 is a hollow circular tube, and several water-absorbing cloths 8 are wrapped around the outside of the mopping roller 3. The water-absorbing cloths 8 are long fiber strip cloths. The mopping roller 3 is driven by a motor 9. The position of the clean water washing device 4 corresponds to the position of the mopping roller 3 and is used to spray clean water onto the water-absorbing cloths 8. Part of the position of the sewage recycling device 5 is directly below the water squeezing roller 2.

[0029] Several diversion grooves 11 are provided on the water squeezing roller 2, and the diversion grooves 11 are spirally distributed on the water squeezing roller 2. The diversion grooves 11 on the water squeezing roller 2 are designed in sections and form V-shaped grooves on the basis of the spiral distribution.
