Abstract
The utility model relates to an electric heating cushion, which belongs to the heating device field of small household electric appliance. An ordinary heating wire which is sheathed with a plastic outer sleeve is positioned and fixed in the inner side of the flange of a circular (square) rigid foam plastic pad, and a power supply with less than 12V is adopted to supply power for the heating wire. The length of the heating wire is set according to the surface temperature of the heat conservation temperature reaching 40 DEG C required by the human body. The electric heating cushion has simple structure, safe use and less power consumption, and the utility model has certain curative effect on sciatica.
Description
The electric heating cushion is to belong to the device that is used for warming oneself in the small household appliances technical field.
It is alternating current (AC) directly-powered that commercially available electric blanket adopts 220V usually in prior art, in case the electric leakage of electric blanket plastic insulating layer cracking meets accident easily, in addition, the heat energy utilization rate is lower in actual applications for electric blanket.
The purpose of the present utility model is in order to overcome the shortcoming of prior art, designs a kind of employing 12V low-tension supply power supply, AC and DC all can, safe in utilization, the electric heating cushion of power consumptive province.
For achieving the above object, the technical solution of the utility model is to adopt the general plastic wrapper heating wire of common electric blanket to place the flange inner at circle (or square) rigid foam edge, adopt the following low-voltage power supply of 12V, by control heating wire resistance (length) surface temperature is set in about 40C, to adapt to human body insulation needs.
The utility model adopts the 12V low-voltage power supply, alternating current-direct current and common stabilized voltage power supply all can, safe in utilization, power consumption is 5W only, in the winter of cold, cushion is placed in the face of stepping on, the people sits on cushions very warm, comfortable and energy-conservation, this electric heating cushion structure is simple, and the sciatica patient is had certain curative effect.
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is further described:
Fig. 1 is the utility model structure principle chart
Fig. 2 is an electric heating cushion profile
As Fig. 1, shown in Figure 2, concrete enforcement of the present utility model is that a flange (3) is made at the outer rim place of a circle (or square) rigid foam pad (1), and the heating wire (2) that will have plastic wrapper again places flange (3) inboard fixing.Heating wire (2) is connected to≤and the temperature that the power supply of 12V (AC and DC all can) will reach 40 ℃ of warming needs of human body according to surface temperature sets the length of heating wire (2).
Claims (1)
1, a kind of electric heating cushion is to be made of heating wire that is with plastic outer sleeve (2) and rigid foam pad (1), it is characterized in that making flange (3) at the outer rim place of garden shape (or square) rigid foam pad (1), the heating wire (2) that is with plastic wrapper places flange (3) inboard fixing.
