Energy-saving electric blanket with continuous warmth keeping function

Abstract

The invention discloses an energy-saving electric blanket with a continuous warmth keeping function, comprising an electric blanket body and a timing circuit connected with an external power supply, wherein the electric blanket body is provided with an upper electric blanket region and a lower electric blanket region; the upper electric blanket region is respectively provided with a first heating resistance wire and a first control circuit; the lower electric blanket region is respectively provided with a second heating resistance wire and a second control circuit; the first control circuit is connected with the first heating resistance wire; the second control circuit is connected with the second heating resistance wire; the input ends of the first control circuit and the second control circuit are connected with the timing circuit after being connected in parallel, and the output ends of the first control circuit and the second control circuit are connected with the external power supply after being connected in parallel; and the timing circuit which is an RC (Remote Control) circuit is also internally provided with a circuit control switch for controlling the whole internal circuit. The energy-saving electric blanket is provided with the upper electric blanket region and the lower electric blanket region and is also provided with the timing circuit, so that not only the warmth keeping function of the electric blanket is optimized, but also the energy source is saved.

Description

technical field [0001] The invention relates to an electric heating blanket, in particular to an energy-saving electric heating blanket with the function of continuously keeping warm. Background technique [0002] At present, the electric blanket has become a kind of requisite daily necessities in people's life, but there are several larger defects in the current electric blanket: 1. The electric blanket is easy to catch fire when used for a long time, which affects the health , but also a waste of electricity; 2. If people only energize the electric blanket before going to bed, so that the electric blanket is preheated for a period of time, and then disconnect the power supply after going to bed, although this can avoid physical discomfort, but sleep until the middle of the night, the electric blanket Basically all the heat will be lost, losing the function of keeping warm. Contents of the invention [0003] The purpose of the present invention is to provide an energy-s...
