  • Patent number: 9149171
    Abstract: A lever-type mop has a base, a cleaning unit, a connecting seat and a rod. The cleaning unit is attached on the bottom of the base. The rod is connected pivotally to the base through the connecting seat. The base has notches and the rod has a corresponding limiting protrusion. A bucket operated in coordination with the lever-type mop has an inclined surface and a straining board mounted under the inclined surface. When straining the cleaning unit, the base and the cleaning unit are put on the straining board and the rod is pivoted downward. With the abutting forces from the limiting protrusion and the inclined surface on opposite sides, the cleaning unit is squeezed. Therefore, the mop and the bucket have simple structures to achieve the purpose of squeezing the cleaning unit without touching the cleaning unit directly by the user's hand.
