| 摘要 |
The present invention is directed to a passive water leak detector 100 comprising a self-contained power source (112,fig.2), a moisture sensor pad 114, an audible / visual alarm 116, and a casing housing the power source, the moisture sensor pad and the alarm. The water detector activates the alarm using the self-contained power source when the moisture sensor pad detects a predetermined level of moisture in a surrounding environment of the water detector. The casing comprises a substantially elongate body 104 having an upper, free end 106, and, a ceiling-abutting plate 108 connected to a lower end of the elongate body 104. The advantage of providing the water detector having a substantially elongate body is that the water detector can be quickly and easily installed in a ceiling by inserting the free end of the water detector through a hole in the ceiling so that a majority of the elongate body is situated above the ceiling, hidden from view, with substantially only the ceiling abutting plate on view. The water detector 100 may further comprise deformable clips (122,fig.1) for securing the detector in a ceiling board. The elongate body 104 may be cylindrical or conical. |
