Abstract
The invention discloses a direct-current non-radiative safety electric blanket, and belongs to the technical field of electric blankets, electric mattresses, electric heating cushions and electric heating bed pads. For a long time, the electric blanket is directly heated by a mains supply. As a power supply is provided with 50Hz oscillating voltage, a human body closely contacts with the electric blanket, a user sleeping on the electric blanket suffers from huge electromagnetic radiation when the electric blanket works, and harm to the human body is quite serious. The direct-current non-radiative safety electric blanket has the advantages that no electromagnetic radiation is generated on the periphery of the electric blanket by a direct-current power supply mode, and the human body cannot be harmed by the electromagnetic radiation.
Description
Technical field
Electric blanket, electric mattress, electro-thermal cushion, Electric heating bed mattress.
Background technology
For a long time, electric blanket all is directly to use civil power to heat.And civil power is voltage is about 220V, frequency is the alternating current about 50Hz.
The Alternating Current Power Supply aspect, because power supply is 50Hz concussion voltage, and the voltage of concussion will produce the electromagnetic wave of concussion, namely electromagnetic radiation around it, human body proximity contact electric blanket, the people who sleeps on electric blanket will bear huge electromagnetic radiation when electric blanket is worked.Very large to harm.
Summary of the invention
The radiationless safe electric blanket of direct current is characterized in that electric blanket adopts the direct current supply mode.
Galvanic characteristics are voltage constants, so do not have electromagnetic radiation to produce around it, and human body is not had hazards of electromagnetic radiation;
The specific embodiment: select the wire that heats of appropriate length, thickness, resistance in electric mattress, evenly to coil or connection in series-parallel, add dc low-voltage voltage at the two ends of wire, wire will generate heat, and whole electric mattress is warmed up, thereby plays the effect of end user's heating.
Claims (7)
1. an electric blanket is characterized in that adopting DC-voltage supply.
2. electric blanket as claimed in claim 1 is characterized in that adopting the mode of AC Electric Heater blanket heating wire parallel connection as heating circuit.
3. electric blanket as claimed in claim 1 is characterized in that adopting the mode of one or more low-resistance electric heated filament series connection as heating circuit.
4. electric blanket as claimed in claim 2 is characterized in that adopting the voltage dc source power supply that is lower than 50V.
5. electric blanket as claimed in claim 2 is characterized in that adopting the voltage dc source power supply that is higher than 50V.
6. electric blanket as claimed in claim 3 is characterized in that adopting the voltage dc source power supply that is lower than 50V.
7. electric blanket as claimed in claim 3 is characterized in that adopting the voltage dc source power supply that is higher than 50V.
