Distance warning device for a male urinal
First Claim
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.

Abstract
A distance warning device for a male urinal comprises a casing, a detector provided at the front end of the casing, and a comparison circuit, a control circuit, and a warning indicator that are electrically connected with the detector. The detector detects the location of a human body. The comparison circuit then outputs a corresponding signal by means of comparison of the detection results. 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 has the warning indicator output a warning signal and has a flusher begin a first-phase flush to pre-wet the male urinal. When receiving a signal indicating that the human body is within the first distance, the control circuit stops the warning indicator. When the distance between the human body and the male urinal is equal to or longer than the second distance, the flusher begins the second-phase flush to wash the male urinal.
