Technical Field

[0001] The utility model relates to the field of floor scrubbers, in particular to a water tank float induction device for a floor scrubber. Background Art

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while sucking up sewage and taking the sewage away from the site. It has the advantages of environmental protection, energy saving and high efficiency, and is mainly divided into semi-automatic floor scrubbers, fully automatic floor scrubbers, push-type floor scrubbers and ride-on floor scrubbers.

[0003] For existing floor scrubbers, after filling with clean water, a certain amount of clean water needs to be added and then the filling is stopped. During the whole process, the operator needs to constantly observe the water level in the water tank to prevent the waste of clean water caused by excessive filling and overflow. There are also transparent liquid level tubes installed on the side wall of the water tank to observe the water level. However, after the clean water in the water tank reaches a certain amount, it is necessary to manually block the water inlet of the water tank to prevent the clean water from overflowing.

[0016] The utility model has the following beneficial effects:

[0017] 1. Before filling the empty water tank with clean water, the annular floating ball is located at the bottom of the water tank. When filling the water tank with clean water through the diversion box later, the annular floating ball will rise along the positioning column as the liquid level inside the water tank rises. When the top of the annular floating ball touches the annular plate, the annular plate will be pushed upward by the annular floating ball. During the upward movement of the annular plate, the two connecting rods connected to its top and the linkage column connected to the outer wall of the top of the connecting rod move along the linkage groove formed inside the U-shaped plate, so that the two U-shaped plates and the connecting blocks respectively connected thereto and the partition plates connected to the other ends of the connecting blocks move relatively closer until the two partition plates are mutually engaged, blocking the clean water from entering the water tank through the diversion box, eliminating the need for the operator to continuously observe the water level, preventing the clean water from being overfilled and overflowing, with simple operation and convenient and fast filling. For existing floor scrubbers, after introducing clean water, a certain amount of clean water needs to be filled and then the filling is stopped. The operator needs to constantly observe the water level in the water tank throughout the process to prevent the clean water from being overfilled and overflowing, resulting in waste of clean water. There are also some that install a transparent liquid level tube on the side wall of the water tank to observe the water level. However, after the clean water inside the water tank reaches a certain amount, it is necessary to manually block the water inlet of the water tank to prevent the clean water from overflowing. This floor scrubber eliminates the need for the operator to continuously observe the water level, prevents the clean water from being overfilled and overflowing, has simple operation and is convenient and fast to fill.

[0018] 2. By connecting a rectangular plate to the outer wall of the annular plate, when the annular plate is completely pushed into the annular groove by the upward movement of the annular floating ball, the rectangular plate is simultaneously located inside the rectangular groove, and at this time, the pressing block connected to the top of the rectangular plate contacts the contact switch at the bottom of the buzzer, causing the buzzer to alarm and remind the operator to close the water valve. A plurality of limiting grooves are provided on the outer wall of the positioning column, and at the same time, a plurality of limiting columns are connected to the inner wall of the annular floating ball. When the annular floating ball rises, the plurality of limiting columns on the inner wall move along the plurality of limiting grooves respectively, making the rising of the annular floating ball more stable.
