Abstract
The utility model relates to an electric heating thermal insulating cushion comprising an electric heating cushion and a temperature-regulated circuit, wherein the electric heating cushion is formed through uniformly arranging an electric-heat wire 2 between two layers of face fabric 1, and the temperature-regulated circuit is formed through connecting one end of the electric-heat 2 with one end of a power supply plug CT, connecting the other end of the electric-heat wire with the anode of a diode D in one circuit and one end of a switch K2 in the other circuit, connecting the other end of the switch 2 with the cathode of the diode D in one circuit and one end of a switch K1 in the other circuit, and connecting the other end of the switch K1 with the other end of the power supply plug CT. The cushion has the characteristics of simple structure, small volume, light weight, convenient carry and the like, when the cushion is needed for strengthening warm for old people or patients, the cushion can be used only through being arranged on a seat, and putting through a power supply, thereby the cushion is very convenient.
Description
Technical field
The utility model relates to a kind of electrothermal cushion in daily living article field.
Background technology
The elderly or patient need to strengthen warming in the winter time, this class crowd is more with sitting posture, also can increase bearing burdens of the elderly or patient if adopt to increase the mode of cotton dress, as utilize air-conditioning or electric heater to heat up to increase energy resource consumption again but also can have influence on other staff's normal life.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of electrothermal cushion is provided.Its technical scheme is: be made up of electric heating cushion and thermoregulation circuit; Wherein form the electric heating cushion by accompanying evenly distributed heating wire 2 in the middle of the two-layer lining 1; An end that connects attaching plug CT by heating wire 2 one ends, heating wire 2 other ends one tunnel connect the positive pole of diode D, another road connects an end of K switch 2, the other end one tunnel of K switch 2 connects the negative pole of diode D, another road connects an end of K switch 1, and the other end of K switch 1 connects the thermoregulation circuit of the other end composition of attaching plug CT.
The utlity model has simple in structure, characteristics such as volume is little, in light weight, easy to carry, the elderly or patient need to strengthen to sit down on the thing to sit on as long as place it in when warming in the winter time, connect power supply and get final product, and be very convenient.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment.
The specific embodiment
Be further described below in conjunction with accompanying drawing: form by electric heating cushion and thermoregulation circuit; Wherein form the electric heating cushion by accompanying evenly distributed heating wire 2 in the middle of the two-layer lining 1; An end that connects attaching plug CT by heating wire 2 one ends, heating wire 2 other ends one tunnel connect the positive pole of diode D, another road connects an end of K switch 2, the other end one tunnel of K switch 2 connects the negative pole of diode D, another road connects an end of K switch 1, and the other end of K switch 1 connects the thermoregulation circuit of the other end composition of attaching plug CT.
During use, plug is inserted power supply, Closing Switch K1 and K2, heating wire 2 can total head heat, and treats that temperature rising back cut-off switch K2 can be incubated, and K switch 2 closures are high temperature, are broken as low temperature, to be suitable for the use down of each environment.
Claims (1)
