Abstract
An automatic flush device is provided that is mounted in a water tank. The automatic flush device includes an inlet control module, a lever module for discharging water and a tank module. The inlet control module includes an inlet element linked to the inlet tube and a solenoid valve set at the inlet element. The lever module for discharging water has a cup connected with the solenoid valve by a filling tube. An electronic sensing controller controls the opening and closing of the solenoid valve to fill water into the cup. When the cup is full of water, the lever unbalances and slants to control the flushing of the water tank. Therefore, it is easy to control water current while requiring minimal power, thereby saving electric energy.

An automatic flush device mounted in a water tank and adapted to receive an outside signal and to control flushing, comprising:
- a water filling control module comprising:
- a water filling part configured to receive water;
- a solenoid valve for controlling a flow of water;
- a water filling tube connected with the solenoid valve;
- and
- an electric sensing controller for receiving an outside signal;
- a lever module comprising:
- a supporting member;
- a lever mounted on the supporting member;
- a cup mounted at a first end of the lever, the cup being fluidly connected with the water filling tube;
- and
- a lifting member set at a second end of the lever;
- an outlet plug connected to the lifting member, and
- a floater for controlling a water level in the water tank.
An automatic flush device mounted in a water tank, comprising:
- a water filling control module comprising:
- a pipe line linked to a water filling tube;
- a solenoid valve set at the pipe line to control a flow of water from the pipe line to the water filling tube;
- a cup rotationally coupled to a lever module for discharging water, wherein the cup is fluidly connected to the water filling tube;
- a tank module;
- and
- an electronic sensing controller for controlling an opening and a closing of the solenoid valve to selectively fill water into the cup, wherein when the cup is full of water, the lever slants to control the flushing of the water tank.
