Intelligent energy-saving electric heating blanket with shrapnel type pressure switch and method for controlling temperature

Abstract

The invention discloses an intelligent energy-saving electric heating carpet with washer type pressure switches and a temperature control method, which is characterized in that: a plurality of washer type pressure switches are arranged inside the electric heating carpet as a matrix, and apart from the heating wires, a direct current power supply of 5V is connected with one end of the washer type pressure switch, and a single-chip microcomputer control circuit with an outlet connected with the heating control circuit of the corresponding matrix is connected with the other end; the opening and disconnection of heating of the area arrayed as matrix are controlled by the single-chip microcomputer control circuit through the combination of the closure of washer type pressure switches. The invention has the advantage of saving electric energy with the precondition of satisfying the normal application requirement of users since the intelligent temperature controlling can be realized by the closure of washer type pressure switches arranged inside the electric heating carpet and pressed by the body through single-chip microcomputer control system, and having simple structure, high reliability and intellectualization.

Description

technical field [0001] The invention relates to an electric heating blanket, in particular to an intelligent energy-saving electric heating blanket controlled by a CPU using a shrapnel pressure switch matrix contact. Background technique [0002] The world's energy shortage has been a topic that has been concerned for many years in various fields all over the world, and many scientists from various countries are also working on the research of energy conservation. In the past, energy conservation and consumption reduction paid more attention to corporate behavior, and less attention was paid to energy conservation and consumption reduction in the lives of ordinary people. The continuity in time makes it have a great impact on the economical use of resources. It is urgent to raise awareness of energy conservation, use energy-saving products, participate in energy-saving actions, and let everyone become the protagonist of energy conservation and consumption reduction. It is u...
