The utility model is achieved in that:

An electric heating sofa, including a main frame, a seat structure, fillers and outer fabrics, the filler is fixed with an electric heating wire wrapped with an insulating material, the armrest on the side of the sofa is equipped with a rechargeable battery, and the outer surface of the armrest of the sofa There is a switch connected in series with the heating wire and the rechargeable battery to form a circuit.

A protective circuit is further connected in series in the circuit formed by the series connection of the switch, the heating wire and the rechargeable battery.

A multi-stage adjustable temperature controller is provided at the junction of the sitting surface and the back of the sofa, and the temperature controller is connected to a circuit composed of a heating wire and a rechargeable battery.

The electric heating sofa of the utility model has the advantages of simple structure, safe and reliable use, can heat the sofa, can help people resist the cold, is especially suitable for elderly and weak people, and improves people's quality of life.

Description of drawings

Fig. 1 is a schematic diagram of a circuit principle of an electric heating sofa;

In the figure: 1 heating wire, 2 rechargeable battery, 3 switch, 4 temperature controller.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Please refer to Figure 1, an electric heating sofa, including a main frame, a seat structure, fillers and outer fabrics, the filler is fixed with an electric heating wire 1 wrapped with an insulating material, and a rechargeable battery 2 is installed in the armrest on the side of the sofa A switch 3 is connected in series with the heating wire 1 and the rechargeable battery 2 to form a circuit on the outer side of the armrest of the sofa.

A protection circuit is further connected in series in the loop formed by the switch 3 being connected in series with the heating wire 1 and the rechargeable battery 2 . The protection circuit may be a short circuit protection circuit such as a fuse. When the switch 2 is turned on, the heating wire 1 generates heat after being energized, thereby increasing the temperature of the sofa and playing the role of keeping warm and keeping out the cold.

A multi-stage adjustable temperature controller 4 is provided at the junction of the sitting surface and the back of the sofa, and the temperature controller 4 is connected to the loop formed by the heating wire 1 and the rechargeable battery 2 .

The temperature controller 4 includes: a temperature sampling circuit, a control circuit and a button display circuit, and the control circuit is connected to the temperature sampling circuit and the button display circuit respectively.

The utility model has the advantages of simple structure, convenient operation and use, and the sofa can be heated through the opening and closing of the switch, which can help people resist the cold, and is especially suitable for the elderly and weak. The temperature of the sofa can also be automatically adjusted through the temperature controller, so that the sofa can always maintain a suitable temperature.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
