Abstract

The invention relates to a water wetting automatic alarm quilt cover which comprises a quilt cover body and an alarm device. The quilt cover body comprises warps and wefts. The wefts are arranged in a plurality of front face electric conduction weft sections, a plurality of non-electric-conduction weft sections and a plurality of back face electric conduction weft sections. The front face electric conduction weft sections and the back face electric conduction weft sections are arranged in a staggered mode. The electric conduction wefts and warps of the front face electric conduction weft sections float on the front face of the quilt cover body after being interwoven. The electric conduction wefts and warps of the back face electric conduction weft sections float on the back face of the quilt cover body after being interwoven. All the electric conduction wefts of the front face electric conduction weft sections are connected. All the electric conduction warps of the back face electric conduction weft sections are connected. The alarm device is connected among the front face electric conduction weft sections and the back face electric conduction weft sections. When the quilt cover is wetted by water, whether an alarm is given or not is determined by the change of resistance value between the electric conduction wefts of the front face electric conduction weft sections and the electric conduction wefts of the back face electric conduction weft sections, and convenience is brought to home life.
