Abstract
There is provided a device attached to the flush valve of an existing stool and adapted for automatically carrying out flushing. This automatic flushing device comprises: a first sensor section for detecting approach and withdrawal of the human body; a second sensor section having a predetermined sensing range and operative to output a detection signal when a portion of the human body exists within the sensing range; a signal processing circuit operative to output a drive signal when the first sensor section detects withdrawal of the human body after more than a predetermined time is passed from the time point when the first sensor section detects approach of the human body, or when the second sensor section outputs the detection signal; an electromagnetic valve mechanism for opening an electromagnetic valve when the drive signal is outputted from the signal processing circuit; and attachment means adapted for accommodating the first and second sensor sections, the signal processing circuit and the electromagnetic valve mechanism, and for attaching them to an existing flush valve.
