As used in the specification of the embodiments of the utility model and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in fig. 1, an embodiment of the present utility model proposes a cleaning robot including a water tank 10, a water tank overflow detecting device, and a base station 100, the base station 100 including a control unit 20. The tank 10 may be a sewage tank. The control unit 20 may be a controller.
The water tank overflow detection device comprises a first magnetic piece 50, a first Hall sensor 60 and a floating piece 70, wherein the first magnetic piece 50 is arranged in the floating piece 70, the floating piece 70 is arranged in the water tank 10, and the first Hall sensor 60 is connected with the control unit 20. The float 70 floats on the water surface in the water tank 10, and when the water level in the water tank 10 reaches a preset overflow level, the first hall sensor 60 senses the first magnetic member 50 and transmits a first sensing signal to the control unit 20. The first sensing signal may be a digital signal or an analog signal, and is determined by the type of the first hall sensor 60. The first hall sensor 60 is provided in the cleaning robot, for example, may be provided in the base station 100.
The float 70 may be embodied as a float ball and the first magnetic member 50 may be embodied as a magnet. The float 70 floats on the water surface in the water tank 10, and moves up and down as the water surface changes up and down.
Working principle: when the water level of the water tank 10 reaches the overflow level, the first magnetic piece 50 is in the detection range of the first hall sensor 60, the first hall sensor 60 senses the first magnetic piece 50 and sends a first sensing signal to the control unit 20, and the control unit 20 judges that the water tank is overflowed and sends out prompt information to remind a user of treatment. When the water level of the water tank 10 does not reach the overflow level, the first magnetic member 50 is not within the detection range of the first hall sensor 60, the first hall sensor 60 does not sense the first magnetic member 50, and at this time, the first hall sensor 60 does not transmit the first sensing signal, so that the control unit 20 determines that the water tank 10 is not overflowed.
Meanwhile, in the embodiment of the utility model, the first magnetic member 50 is installed in the water tank 10, and the first hall sensor 60 is installed in the cleaning robot, so that no circuit is required to be arranged in the water tank 10, the influence of water vapor in the water tank on the circuit can be avoided, the safety is improved, and the service life of electronic components is prolonged.
According to the technical scheme of the embodiment of the utility model, the first magnetic piece 50 is arranged in the floating piece 70 in the water tank 10, when the water tank overflows, the first Hall sensor 60 can detect the first magnetic piece 50 and send a first induction signal to the control unit 20, at this time, the control unit 20 judges that the water tank overflows, sends out prompt information and reminds a user of processing, so that the water tank overflow detection function can be accurately realized.

The floating member 70 is provided with a sliding groove 90, and the sliding rail is embedded in the sliding groove 90. When the water level in the water tank 10 rises, the float 70 rises along the guide rail 80 under the buoyancy. When the water level in the tank 10 rises, the float 70 descends along the guide rail 80 by gravity. The guide rail 80 plays a guiding role, so that the floating member 70 can fixedly slide along the guide rail 80, and the phenomenon that the floating member 70 does not fixedly move in the water tank 10 to cause inaccurate detection is avoided.
Further, when the water level in the water tank 10 reaches the preset overflow level, the distance between the first magnetic member 50 and the first hall sensor 60 is smaller than or equal to the first maximum detection distance of the first hall sensor 60. The first maximum detection distance is determined by the type of the first hall sensor 60, typically 30mm. The first magnetic member 50 is within a maximum detection distance and is detectable by the first hall sensor 60.
In an embodiment of the present utility model, the first magnetic member 50 may be a magnet.

Because the utility model only needs to know whether the magnetic field exists or not to judge whether the water level of the water tank 10 reaches the overflow position, and only needs to reach the judgment threshold value of the magnetic field, a signal of 0 or 1 is output, and analog quantity output of accurately knowing the intensity of the magnetic field is not needed; bipolar detection can facilitate the production process without distinguishing between the north and south poles of the magnet.
Meanwhile, the output quantity of the first Hall sensor 60 which is digitally output is just provided with a judging buffer zone, and in the process of judging the rising of the water level, the first Hall sensor 60 is prevented from being continuously triggered due to the shaking of the water in the water tank, so that the actual application requirement is met.

When the water tank 10 is detached from the base station 100, the second magnetic member 30 is not within the detection range of the second hall sensor 40, and the second hall sensor 40 cannot sense the second magnetic member 30, and at this time, the second hall sensor 40 does not transmit the second sensing signal, whereby the control unit 20 determines that the water tank 10 is not in place.
According to the technical scheme of the embodiment of the utility model, the second magnetic piece 30 is arranged on the water tank 10, the second Hall sensor 40 is arranged on the base station 100, and when the water tank is in place, the second Hall sensor 40 can detect the second magnetic piece 30 and send a second induction signal to the control unit 20, so that the control unit 20 judges that the water tank is in place, and the water tank in-place detection function can be accurately realized.
