Abstract
The utility model provides an automatic power off electric blanket. A delay relay is arranged in a supply circuit of an electric blanket, a plurality of heating elements in series connection are mounted in an interlayer which is arranged in the electric blanket, and the heating elements are connected with the delay relay. The delay relay of the automatic power off electric blanket can be automatically powered off when the electric blanket is powered on for some time or reaches a certain temperature, so that troubles caused by excessively power on are avoided. The automatic power off electric blanket is simple in structure, convenient in use, low in power consumption and more environmental-friendly, and is capable of effectively reducing influences on human body.
Description
Technical field
The utility model relates to a kind of electric blanket, relates in particular to a kind of electric blanket that can cut off the power supply automatically.
Background technology
In winter, electric blanket is that we use article always, and in bed, Jiang Qipu can heat rapidly in bed, and it is more comfortable that we are slept, and the power consumption of electric blanket is little, and use cost is low; Volume is little, and is light and handy and be easy to carry, and deposits, and uses very convenient.
But electric blanket also has deficiency, if the electric blanket long-time heating can feel that temperature is too high by let us, and also dry, so not only influence our sleep, also can cause adverse influence to our skin; Can generate electromagnetic waves after the electric blanket energising, and human body is very responsive for electromagnetic wave, if electric blanket is in "on" position for a long time, makes us long-term be in the electromagnetic wave environment, also can endanger people's health; Be in for a long time under the energising duty, the circuit of electric blanket can produce aging, so also can cause the generation of contingency.
Electric blanket has brought easily to our life and has also brought us a series of urgent problems simultaneously.
The utility model content
The utility model provides a kind of electric blanket of automatic outage, is connected to time-delay relay on electric blanket, when the electric blanket use reaches certain hour, and outage automatically, the problem of having avoided the excessive energising of electric blanket to bring.
A kind of logical electric blanket of outage automatically of the utility model is crossed following technical scheme and is realized purpose:
A kind of electric blanket of automatic outage comprises the electric blanket as main body, wherein, is provided with time-delay relay in the power supply circuits of described electric blanket; Be provided with interlayer in the described electric blanket, a plurality of heatings are housed in the described interlayer, described a plurality of heatings are connected in series; Described heating is electrically connected with described time-delay relay.
The electric blanket of above-mentioned automatic outage, wherein, described heating comprises heat-resisting core, lectrothermal alloy wire and heat-resistant resin layer; Described lectrothermal alloy wire is entangled on the described heat-resisting core, and described heat-resistant resin layer is positioned at outermost layer.
The electric blanket of above-mentioned automatic outage, wherein, described time-delay relay is provided with time-controlling arrangement.
The electric blanket of above-mentioned automatic outage wherein, also is provided with temperature inductor in described electric blanket, described temperature inductor is provided with radio-signal transmitter.
