Abstract
The utility model relates to an anticarcinogenic stepless temperature controlling protector capable of eliminating low frequency field for electric heating blankets. The utility model can thoroughly eliminate low frequency magnetic field produced by electric blankets and can also have stepless temperature controlling. Matched with an electric blanket directly, the use of the electric blanket gets safe, convenient and more comfortable. Scientists point out that low frequency field can induce cancers, about 30% of the cancerous patients are relevant to the low frequency field. A study on cancerous patients indicates that people whose sleep on electric blankets have a rate of inducing cancer 47% higher than people whose do not. The scientists, therefore, appeal for not using electric blankets. The utility model which thoroughly eliminates the low frequency field is capable of preventing cancers, curing diseases and keeping good health and has simple structure and low cost.
Description
The utility model relates to electric blanket frequency elimination anti-cancer stepless temperature regulating protector, particularly a kind ofly eliminates the electric blanket protector that low frequency magnetic field prevents that cancer from producing.Various electric blankets are adapted directly, but and stepless temperature regulating, be the electric blanket protector of guaranteeing that the health of human body diseases prevention is suitable for.
The electric blanket of people's use at present all exists low frequency alternating magnetic field.According to electronics reports of newspaper scientists: " low frequency magnetic field can bring out cancer, and nearly 30% cancer patient is relevant with extremely low frequency magnetic field ".
This novel purpose is that a kind of electric blanket protector will be provided, and it can eliminate the low frequency magnetic field that electric blanket produces, and prevents the generation of cancer, and can electrodelessly adjust.It is promptly convenient, more comfortable again safely that electric blanket is used.
Be achieved in that the order that this is novel
In alternating current circuit, bidirectional triode thyristor is subjected to electric capacity, potentiometer and bidirectional trigger diode to control its angle of flow, realizes the purpose of stepless temperature regulating.The potentiometer coupled switch is directly undertaken another open and close of surveying power supply.Be added in the AC side of drag flow bridge by the electric current of pressure regulation or not pressure regulation, the direct current behind the drag flow connects load socket at the pure direct current of output behind capacitor filtering, directly takes for electric blanket.Thereby eliminated the low frequency magnetic field that electric blanket produces, prevented the order ground of the production of cancer.
The drawing of accompanying drawing is described as follows:
Among the figure: 1,2 electric capacity, 3 bidirectional triode thyristors, 4 two-way triggering diodes, 5 potentiometers, 6 drag flow bridges, 7 switches, 10,11,12,13 drag flow bridge joint line ends, 15 sockets.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:
Among the figure: an end of electric capacity 1 links to each other with an end of bidirectional triode thyristor, meet power line A, diode 4 is sent out in the other end contact of electric capacity 1, one end of potentiometer 5, trigger the control utmost point of another termination bidirectional triode thyristor of diode, the other end of another termination bidirectional triode thyristor 3 of potentiometer 5 and 11 ends of drag flow bridge, regulator potentiometer changes the silicon controlled trigger point, exports electrodeless adjustable voltage.Power line b connects an end of switch 7, and 10 ends of 7 the other end and drag flow bridge 6 join, 12 ends of drag flow bridge 6 and the positive pole of electric capacity 2, and an end of socket 15 joins, 6 13 ends and the negative pole of electric capacity 2, the other end of socket 15 joins.Electric blanket is operated in the DC circuit.Thoroughly eliminated the harm of low frequency magnetic field to human body.
The utility model only has the following advantages compared to existing technology:
1, the utility model makes electric blanket can not produce low frequency magnetic field, thereby has solved the harmful effect of low frequency magnetic field to human body owing to adopt direct current supply, subtracts The generation of few cancer makes people's health more healthy.
2, adopt the bidirectional triode thyristor stepless pressure regulation, make the temperature of electric blanket be able to stepless regulating. Use of the present utility model, the i.e. safety that the performance of electric blanket becomes is again convenient, more comfortable.
3, owing to adopt stepless pressure regulation, freely select temperature, can save the energy, it is useless to reduce unnecessary wave.
