Floor cleaner and water sink structure thereof
The present invention provides a floor cleaner and a water sink structure thereof. In the present invention, a water sink is formed on a surface of a cleaning cylinder by a rotating roller, and a conventional water sink structure formed by a shell water sink and a filter screen is not required, so that the structure is simpler. Since a water outlet conduit and a water pumping conduit are arranged vertically to the surface of the cleaning cylinder, water is discharged and pumped on a surface of an outer sponge layer, the water supply and water pumping systems will not be blocked, and the water discharge effect and the water pumping effect are better.
1. A water sink structure for a floor cleaner, characterized by comprising a cleaning cylinder and a rotating roller, wherein the rotating roller is disposed on a front side of the cleaning cylinder in parallel and forms an included angle with an upper end of the cleaning cylinder; the included angle between the rotating roller and the cleaning cylinder forms a water sink on a surface of the cleaning cylinder; the rotating roller squeezes the surface of the cleaning cylinder; a water outlet conduit is provided at one end of the water sink, while a water pumping conduit is provided at the other end thereof; and, both the water outlet conduit and the water pumping conduit are arranged vertically to the surface of the cleaning cylinder.
2. The water sink structure for a floor cleaner according to claim 1 , characterized by further comprising a driving device; one end of the rotating roller is in driving connection to the driving device; and, the driving device drives the rotating roller to rotate and brings the cleaning cylinder to roll towards the front side.
3. The water sink structure for a floor cleaner according to claim 2 , characterized in that the driving device is a driving motor.
4. The water sink structure for a floor cleaner according to claim 1 , characterized by further comprising a fixed frame, two ends of the cleaning cylinder and the rotating roller being rotatably connected to the fixed frame.
5. The water sink structure for a floor cleaner according to claim 1 , characterized in that the cleaning cylinder comprises a sleeve, an inner sponge layer and an outer sponge layer, the inner sponge layer is sleeved on a surface of the sleeve, and the outer sponge layer is sleeved on a surface of the inner sponge layer.
6. The water sink structure for a floor cleaner according to claim 5 , characterized in that the inner sponge layer is a water-repellent sponge layer, the outer sponge layer is a water-absorbent sponge layer, and the thickness of the outer sponge layer is less than that of the inner sponge layer.
7. The water sink structure for a floor cleaner according to claim 1 , characterized in that a distance from the water pumping conduit to the surface of the cleaning cylinder is 0.2 mm to 2.0 mm.
8. A floor cleaner using the water sink structure according to claim 1 .
