Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a sewage tank structure and a floor washer. Background Art

[0002] Traditional floor washers rely on a floating ball to float up and block the water suction pipe. Not only can it not block, but it is also easy to cause water to be sucked into the water suction motor, and there may be debris in the sewage. Sucking into the water suction motor may cause blockage or damage to the water suction motor. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that traditional floor washers rely on a floating ball to float up and block the water suction pipe. Not only can it not block, but it is also easy to cause water to be sucked into the water suction motor, and there may be debris in the sewage. Sucking into the water suction motor may cause blockage or damage to the water suction motor.

[0004] To solve the above technical problem, the utility model provides a sewage tank structure, which includes a sewage tank, a cavity, a tank cover and a water suction motor. The upper part of the sewage tank is communicated with the upper part of the cavity. The air inlet of the water suction motor is communicated with the cavity. The tank cover covers above the sewage tank and the cavity, and the tank cover makes the sewage tank and the cavity airtight with the outside. The tank cover, the sewage tank and the cavity form a sealed cavity. When the water suction motor works, a negative pressure environment is formed in the sealed cavity, so that sewage can be sucked from the ground into the sewage tank.

[0005] Further, the cavity is arranged inside the sewage tank. The upper end of the cavity is open, and the upper end of the sewage tank is open. The upper end opening of the cavity is communicated with the upper end opening of the sewage tank. The water suction motor is communicated with the upper end opening of the cavity. When the water suction motor works, a negative pressure environment is formed in the sealed cavity formed by the sewage tank, the tank cover and the cavity, so that sewage can be sucked from the ground into the sewage tank.

[0006] Further, the cavity is arranged outside the sewage tank. The upper end of the cavity is open, and the upper end of the sewage tank is open. The upper end opening of the cavity is communicated with the upper end opening of the sewage tank. The water suction motor is communicated with the upper end opening of the cavity. When the water suction motor works, a negative pressure environment is formed in the sealed cavity formed by the sewage tank, the tank cover and the cavity, so that sewage can be sucked from the ground into the sewage tank. At the same time, the cavity is arranged outside the sewage tank, which further prevents the sewage and debris in the sewage tank from entering the water suction motor. At the same time, the cavity is arranged outside the sewage tank, preventing the sewage sucked into the sewage tank from splashing into the water suction motor when the sewage storage in the sewage tank is relatively high, causing blockage or damage to the water suction motor.

[0007] Further, an annular partition is provided inside the cavity. The water suction motor is communicated with the annular partition. The upper end of the annular partition is open, and the upper end of the sewage tank is open. The upper end opening of the annular partition is communicated with the upper end opening of the sewage tank. When the water suction motor works, a negative pressure environment is formed in the sealed cavity formed by the sewage tank, the tank cover and the cavity, so that sewage can be sucked from the ground into the sewage tank. At the same time, there is a chamber between the annular partition and the cavity. When sewage or sundries enter the cavity, the sundries and sewage will first enter this chamber and will not enter the water suction motor in a short time, causing blockage or damage to the water suction motor.

[0008] Further, the cavity includes a first cavity and a second cavity. A filter element is provided in the first cavity, and a filter screen cylinder is provided in the second cavity. The filter element provided in the first cavity filters the sewage or sundries entering the cavity for the first step, and the filter screen cylinder in the second cavity filters the sundries entering the cavity for the second step, further preventing sewage or sundries from entering the water suction motor and causing blockage or damage to the water suction motor.

[0009] Further, a baffle is also included. The baffle is arranged outside the cavity and the water suction motor. The two baffles form a groove. When sewage or sundries overflow from the sewage tank, the sewage or sundries will first enter this groove and will not enter the water suction motor in a short time, causing blockage or damage to the water suction motor.

[0010] Further, a controller is also included. A water level switch is provided at the opening inside the sewage tank. The water level switch is electrically connected to the controller, and the water suction motor is electrically connected to the controller. When the sewage liquid level in the sewage tank rises and contacts the water level switch, the water level switch sends a signal to the controller, and at the same time, the display light lights up to remind the staff. After receiving the signal sent by the water level switch, the controller controls the water suction motor to stop working.

[0011] Further, a detection element, a floating ball and a limiting plate are also included. The detection element is arranged at a position near the opening at the upper end inside the sewage tank. A limiting plate is arranged on one side of the detection element. The limiting plate is provided with holes. A floating ball is arranged between the limiting plate and the side wall of the sewage tank. When the sewage liquid level in the sewage tank rises, the floating ball moves upward under the constraint of the limiting plate at the same time. When the floating ball contacts the detection element, the controller receives the signal and controls the water suction motor to stop working at the same time. The holes are provided on the limiting plate to prevent the pressure on both sides of the limiting plate from being unequal and the water suction motor from working better.

[0012] Further, a drain plug is also included. The drain plug is arranged at the bottom of the sewage tank. The design of the drain plug enables the sewage and sundries in the sewage tank to be smoothly discharged after the floor washer completes the floor washing work.

[0013] Further, it also includes a box body. A transparent connecting pipe is arranged on the outer side of the box body close to the sewage tank. The design of the transparent connector enables the staff to detect the sewage storage in the sewage tank through the height of the liquid level in the transparent connector when performing floor washing work.
