Abstract:
1. A water leak warning device comprising: a hollow body having an interior space and an outer surface, the hollow body having rigid walls comprising a top wall, a bottom wall and a side wall, the bottom wall having a circular bottom flat surface, the bottom flat surface having peripheral edges bordering the side wall, and the top wall having an upper flat surface, a lower flat surface and an aperture extending from said upper that surface to said lower flat surface thereby fluidly connecting said interior space to an external environment; a plurality of protruding elements having substantially equal height rooted on a lower end of the side wall as extensions of the side wall in a direction generally perpendicular to the bottom flat surface, wherein there are gaps between the protruding elements; two electrodes each having a first end and a second end, the first ends of the electrodes protruding out of the bottom flat surface in a direction generally perpendicular to the bottom flat surface, the second ends of the electrodes being enclosed in the interior space of the hollow body; a power supply irreplaceably enclosed in the interior space of the hollow body; a piezoelectric buzzer enclosed in the interior space of the hollow body, said piezoelectric buzzer being located such that a sound emitting hole of said piezoelectric buzzer is located proximate to said aperture through said top wall; an amplifier enclosed in the interior space of the hollow body; and wherein the electrodes, the power supply, the piezoelectric buzzer and the amplifier are operatively connected by conducting elements such that when the first ends of the two electrodes are connected by a conductive material, an audible signal is emitted by the piezoelectric buzzer.
