Abstract
The utility model relates to an electrically heating pad, wherein, a plurality of electrically heating wires with high degree of insulation are distributed evenly in the interlayer of a fabric pad. Both ends of the electrically heating wires are connected with the multi-shift regulating switch of a thermostat through electric plug-ins. Multi-channel safe and low voltage output wires are arranged on a secondary coil of a transformer and are correspondingly connected with the shift contacts of the multi-shift regulating switch respectively; wherein the safe and low voltage output wire of the highest voltage is connected with a power switch, a rectifier cell VD, a resistance R2 and a relay J in series; the power switch is connected with a power indicator and a resistance R1 in parallel. The utility model has the advantages of 15 to 24V safety voltage, short circuit protection, safe and reliable use, and auxiliary medical functions of multi-shift temperature adjusting and promoting the local blood circulation.
Description
Technical field
The utility model relates to a kind of electrical home appliances, particularly a kind of electric pad.
Background technology
The heating wire of existing electric blanket or electric pad is 220 volts of alternating currents that directly pass to without step-down rectifier, and it is complete to feel unwell; Temperature adjustment has only two grades of height, and the temperature adjustment gear is few.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of electric pad that adopts safe voltage, many grades of temperature adjustments.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electric pad, its high-intensity heating wire is distributed in the interlayer of fabric pad, and the two ends of heating wire link by many grades of regulating switch of electric plug and thermosistor, the corresponding binding of output lead of the latter and transformer.The power inleting terminal of transformer is provided with fuse, transships instant cut-off protection when overheated.The secondary coil of transformer be provided with 2-6 road safety low-voltage output lead and respectively with the corresponding binding in the gear contact of many grades of regulating switch, wherein the safe low-voltage output lead of ceiling voltage is connected with power switch, rectifier cell VD, resistance R 2 and relay J, and power switch is in parallel with power supply indicator and resistance R 1.Two outputs of many grades of regulating switch and socket link, and in parallel with electric pilot lamp and resistance R 3.
The beneficial effects of the utility model are: it is after transformer isolation, and output is unloaded for 15-24V exchanges safe voltage, gives high-intensity heating wire power supply after rectification.Electric pad is put in bed, replaced hot-water bottle can warm up pin, also can make the warm cushion of electricity.The highest warming temperature can reach 85 ℃, because of being local heat, so can promote the local blood circulation, as positions such as waist, shoulder, pin, therefore also can doing medical assistance and use.Its power is 6-12W, and heat supply is concentrated and efficient is high; Be provided with short-circuit protection, safe and reliable during use, have many grades of temperature adjustment functions simultaneously, easy to use, the inner bag softness is durable in use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment is shown in Fig. 1-2: a kind of electric pad, and its high-intensity heating wire 2 is distributed in the interlayer of fabric pad 1, and the two ends of heating wire 2 link by the many grades of regulating switch 4 of plug 9 and socket 10 and thermosistor 3.The power inleting terminal of transformer 6 primary coils is provided with fuse 11, transships instant cut-off protection when overheated.After the pin of transformer 6 inserts supply socket, its secondary coil is exported four groups and is exchanged safe low-voltage, and respectively with the corresponding binding in four gear contacts of many grades of regulating switch 4, wherein ceiling voltage is that 24 volts output lead is connected with power switch 8, rectifier cell VD, resistance R 2 and relay J, and power switch 8 is in parallel with power supply indicator 7 and resistance R 1.Two outputs of many grades of regulating switch 4 and socket 10 link, and in parallel with electric pilot lamp 5 and resistance R 3.
After transformer 6 is connected power supply, light LED 17, show that transformer 6 has the power supply input; After pressing power switch SB 8, the relay J adhesive, while J1-1 closure, LED 17 extinguishes.Stir many grades of regulating switch 4 and import contact 1,2,3 or 4 by zero point to low-voltage, electric pilot lamp LED2 5 is bright, and electric pad is started working, and temperature raises by shelves by 1 to 4, and the highest warming temperature is controlled at 85 ℃.Output is if any short circuit in the work, and relay just opens circuit immediately, thereby plays the safeguard protection effect.
