1. A distance warning device for a male urinal, comprising:

  • a casing;

    a detector, provided at the front end of the casing, for detecting the location of a human body;

    a comparison circuit, electrically connected with the detector, for comparing and outputting a signal indicating that the distance between the human body and the male urinal is shorter than a first distance or is between the first distance and a second distance; and

    a control circuit, electrically connected with the comparison circuit, where when receiving a signal indicating that the distance from the human body to the male urinal is between the first distance and the second distance, the control circuit controls a warning indicator to output a warning signal and to have a flusher begin a first-phase flush to pre-wet the male urinal;

    when receiving a signal indicating that the distance between the human body and the male urinal is smaller than the first distance, the control circuit stops the warning indicator; and

    when receiving a signal indicating that the distance between the human body and the male urinal is equal to or longer than the second distance, the control circuit controls via a processor the flusher to begin a second-phase flush to wash the male urinal.
