Patent ID: 8324533

Claim:
A dual-person electric heating blanket comprising: a receiving bag, said receiving bag is provided therein with a first heating wire and a second heating wire juxtaposed with each other, said first and second heating wires are connected with a controller box which includes a signal receiver end and two control circuits with which heating temperatures of said two sets of heating wires are controlled respectively; and a remote controller including an electric circuit board being electrically connected, a pattern interface, a switchable switch and a signal emitting end, wherein said circuit board is provided therewith a first circuit and a second circuit, said pattern interface has thereat a first and a second position juxtaposed with each other, said first position has thereat a first pattern, and said second position has thereat a second pattern, said first and said second circuits are respectively connected with said first and second patterns; wherein said switchable switch includes a first raised plate, a second raised plate, an inversed U shaped first conductor, an inversed U shaped second conductor and a metallic ball, said first and said second raised plates are juxtaposed with each other, and a slit is formed between said first and said second raised plates, said first and said second conductors are juxtaposed with each other, one leg of said first conductor and one leg of said second conductor are respectively connected to said first raised plates, while another leg of said first conductor and another leg of said second conductor are respectively connected to said second raised plates; while said metallic ball is placed between said first and said second conductors on said first and said second raised plates; thereby, when a user faces to a front or a rear end of said receiving bag, by switching between said first and said second circuits with said switchable switch, said first pattern corresponds to said first heating wire and said second pattern corresponds to said second heating wire, and by emitting control signal from said signal emitting end, heating temperatures of said two sets of heating wires are controlled respectively.
