Abstract

An automatic flushing device for a flush toilet comprising an infrared sensor (231) and an electronic circuit connected with the infrared sensor (231), which is possible to sense the length of time the toilet has been used and to actuate the electronic circuit to energize a coil (24) to move magnetically up a round block (31) connected with a rhonboidal (3 ball (35) normally blocking an outlet (4) of a tank for three different lengths of time and accordingly for flushing water in three different volumes out of the outlet (4) <IMAGE>
