The lower part of the moving push rod 1 is provided with a thrust floating ball 7, the thrust floating ball 7 is positioned in the water tank 13, the moving push rod 1 is sleeved with a check ring 8, the check ring comprises a first check ring and a second check ring, and the upper end of the moving push rod 1, which is positioned on the thrust floating ball 7, is sleeved with the first check ring. The limiting pin 9 is arranged on the moving push rod 1, the limiting pin 9 comprises a first limiting pin and a second limiting pin, the first limiting pin is arranged on the moving push rod 1, the first limiting pin is located above the first thrust floating ball 7, the first limiting pin limits the first retaining ring to move upwards on the moving push rod 1, the second retaining ring is sleeved below the thrust floating ball 7 on the moving push rod 1, the second limiting pin is arranged on the moving push rod 1, the second limiting pin limits the second retaining ring to move downwards on the moving push rod 1, the thrust floating ball 7 is sleeved on the moving push rod 1, the first retaining ring limits the upward movement of the thrust floating ball 7 on the moving push rod 1, and the second retaining ring limits the downward movement of the thrust floating ball 7 on the moving push rod 1.

The lateral part of mount pad 2 sets up on-off switch 5, and on-off switch 5 is connected with electrical apparatus control box 12, sets up motion arm 4 on the on-off switch 5, and the one end of motion arm 4 is rotated and is installed on mount pad 2, and the other end overlap joint of motion arm 4 is in the upper end of motion push rod 1. The upper end surface of the motion push rod 1 is a convex cambered surface, so that the contact resistance between the motion push rod and the motion arm 4 is reduced. The moving push rod 1 moves upward to push the moving arm 4 to rotate clockwise, thereby switching the on-off switch 5 to the on state. The moving push rod 1 moves downwards, and the moving arm 4 rotates anticlockwise under the action of gravity, so that the on-off switch 5 is switched to a normally open state.

Preferably, a contact lever 41 is disposed at one end of the moving arm 4, and during the clockwise rotation of the moving arm 4, the contact lever 41 pushes the gate rod 51 of the on-off switch 5 to close the circuit. The return spring 52 on the brake lever 51 is compressed, and in the process of counterclockwise rotation of the moving arm 4, the abutting lever 41 gradually reduces the acting force on the brake lever 51, the brake lever 51 is restored to the natural state position under the action of the return spring 52, and the on-off switch 5 is in the normally open state.

In addition, conflict pole 41 also can be connected with brake lever 51, cancel return spring 52, the in-process that the water level rose to the gap, and motion arm 4 drove conflict pole 41 and rotates, and brake lever 51 is last to set up spout 43 along length direction, and conflict pole 41 passes through axis of rotation 42 sliding connection in the spout 43 of brake lever 51, and conflict pole 41 promotes brake lever 51 and closes a floodgate, and on-off switch 5 switches on, and in-process that the water level descends, motion arm 4 drives conflict pole 41 counter-rotation, and conflict pole 41 pulling brake lever 51 breaks a floodgate, and on-off switch 5 breaks off.

The water inlet pipe of the water tank 13 is provided with a water tank water inlet electric valve 11, and the water tank water inlet electric valve 11 is connected with an electric appliance control box 12. An overflow pipe 10 with a downward opening is arranged at the overflow opening of the water tank 13.

The working principle is as follows: when the water level of the water tank 13 is at the normal liquid level position, the moving push rod 1 is at the descending position, the radial baffle 6 clings to the tank body of the water tank 13 to limit the moving push rod 1 to continue moving downwards, at the moment, the buffer spring 3 is in the stretching state, the moving arm 4 is in the relieving state, the on-off switch 5 is in the normally open state, and the water tank water inlet electric valve 11 is in the normally open state.

Once the water level exceeds the upper limit water level, the water level firstly touches the thrust floating ball 7 before reaching the overflow water level, under the buoyancy action of water, the floating ball 7 drives the moving push rod 1 to move upwards and pushes the moving arm 4 to move, so that the on-off switch 5 is switched to a conducting state, and meanwhile, the moving push rod 1 compresses the buffer spring 3, so that the instantaneous impact force generated in the moving process of the push rod is relieved.

When the on-off switch 5 is turned on, a signal is transmitted to the water inlet electric valve 11 of the water tank and is switched from a normally open state to a closed state, so that water is not filled into the water tank 13, and the water tank 13 is prevented from overflowing. In addition, when the on-off switch 5 is switched on, the audible and visual alarm system is started, the alarm lamp flickers, and the buzzer gives out an alarm sound. And after the alarm is released, the liquid level over-limit early warning device is restored to the initial state.

The above description has been made in detail only for the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art, and all such changes are intended to be encompassed by the present invention.
