ABSTRACT:
An automatic flushing apparatus includes an electromagnetic valve, an electrical controlling apparatus in conjunction with the electromagnetic valve for effecting an automatic flushing operation. A first closed tank communicates to the outlet tube of the electromagnetic valve. An upright cylindrical tank is connected to the first closed tank and has a tube member extending inwardly from a central opening at the top end of the cylindrical tank. A piston member is slidably received in the tube member and is biased by a coil spring. A second closed tank contains an antiseptic solution and communicates to the tube member of the cylindrical tank by means of a connecting pipe. The connecting pipe has a branch pipe with an elastic rubber nipple member connected to the first closed tank. A check valve assembly is provided in the connecting pipe, which permits the antiseptic solution to flow from the second closed tank into the connecting pipe when the piston member is moved downward. The antiseptic solution in the connecting pipe is squeezed into the first closed tank through the nipple member when the piston member is forced upward against the biasing force of the coil spring.
