When the pressure signal sensed by the pressure sensor 4 exceeds the preset value, the signal is transmitted to the controller, and the controller controls the driver to work. The power output end of the aforementioned driver is connected to the slag basket 2 for driving the slag basket 2 to drive the slag basket 2 to rotate around its own axis.

[0046] When draining in the water storage state, when the cover is opened, water will flow into the lower water chamber through the top opening of the lower water chamber, and the pressure sensor under the slag basket will sense the water pressure and drive the motor to operate. The motor drives the slag basket to rotate through the transmission mechanism. During the rotation process, the blades on the side walls of the slag basket can generate eddy currents and centrifugal force to quickly discharge the water in the slag basket. For daily drainage without water storage, when the cover is opened, the pressure of the flowing water can also be captured by the pressure sensor, and the motor can be activated to achieve drainage. The motor continuously drives the slag basket to rotate for a period of time, and the garbage in the filter basket can be centrifugally dried. After drying, the motor stops running, and the filter basket is lifted out to dump the dry garbage.
