Abstract
The utility model provides a direct current magnetotherapy electric blanket, its technical essential is: a direct current rectification power supply is connected between the alternating current power supply and the electric heating wire, and the electric heating wire is arranged on the blanket surface according to a spiral rule. After the power supply is switched on, the direct current flows through the electric heating wire, and the electric blanket heats. In addition, according to the right-hand spiral law, a direct-current weak magnetic field exists in the vertical direction of the blanket surface, the center of the direct-current weak magnetic field is strongest, and the direct-current weak magnetic field has certain magnetic therapy effect on a human body. It can eliminate the alternating magnetic field existing around the electric blanket. Eliminating the interference of the human body. The utility model discloses be fit for the family and use when heating winter.
Description
The utility model belongs to a kind of electric blanket, particularly a kind of electric blanket that adopts direct current supply.
General electric blanket all is an Alternating Current Power Supply, therefore there is alternating electromagnetic field at the electric blanket surrounding space, after the people lies on this blanket, in human body, generate alternating current, like this human body vegetative nerve and bioelectricity are had interference effect, the long-term use can make people's spirit produce dysphoria, even have difficulty in going to sleep, unsound people feels more obvious to heart.
The purpose of this utility model provides a kind of DC electrothermal blanket that can avoid above-mentioned deficiency.
The purpose of this utility model is achieved in that between AC power and heating wire, is connected with dc rectification power, and heating wire is pressed the wiring of spiral rule in the blanket.After the energized, direct current flows through heating wire, electric blanket heating.In addition, by right-hand screw rule, with blanket face vertical direction on, have a direct current low-intensity magnetic field, this magnetic field center is the strongest, and human body is had certain magnetotherapy effect.
Be described further below in conjunction with accompanying drawing.
Fig. 1 is an electrical schematic diagram of the present utility model.
Fig. 2 is the utility model structural representation.
Fig. 3 is the cutaway view of Fig. 2 along the A-A line.
Referring to Fig. 1, DC power supply adopts four diode D2-D5 to form bridge rectifier, powers to heating wire RL.Referring to Fig. 2, heating wire 4 is pressed the spiral rule in evenly wiring on 3 in the blanket, the end of a thread (negative pole) of inner lane need be drawn, link the DC power supply 2 that is positioned at the blanket angle, for preventing lead-out wire and heating wire, be surrounded by glass fibre conduit 5 and Fire-retarded blanket 6(in the outside of lead-out wire) referring to Fig. 3 owing to the overheated short circuit phenomenon that produces.Open switch 1 during use, through rectifier power source, direct current flows through heating wire, the heating wire heating, simultaneously with blanket face vertical direction, there is the low-intensity magnetic field of a direct current, human body is had certain magnetotherapy effect, particularly have certain curative effect hypertension, bronchitis, arthritis and nerve are weak.
In order to strengthen magnetic therapy effect, also can on the blanket face, place a permanent magnet pieces consistent at the human body privileged site with the utility model magnetic direction.
Compared with prior art, the utility model has been eliminated the friendship magnetic field that exists around the electric blanket, has got rid of it to the interference of human body, rebulid the direct current low-intensity magnetic field, so it also will produce certain magnetic therapy effect to human body.
Claims (2)
1, a kind of direct current electric heating blanket for magnetic therapy is made up of blanket face and heating wire, it is characterized in that: between AC power and heating wire, be connected with dc rectification power, heating wire is pressed the wiring of spiral rule on the blanket face.
2, direct current electric heating blanket for magnetic therapy according to claim 1 is characterized in that: the appearance by the lead-out wire of inner lane after the spiral wiring is surrounded by glass fibre conduit and Fire-retarded blanket.
