Separate control electric heating pad

Abstract

The invention relates to a separate control electric heating pad. At least one layer of first needle-punched cotton unit and a second needle-punched cotton unit are attached to and matched with the surface of the inner wall of a cloth sleeve body, wherein at least one layer of first non-woven fabric unit is attached to and matched with the inner wall of the first needle-punched cotton unit; and correspondingly, at least one layer of second non-woven fabric unit is attached to and matched with the inner wall of the second needle-punched cotton unit, and at least one layer of third needle-punched cotton unit is attached and matched between the second non-woven fabric unit and the first non-woven fabric unit; an interface block is matched with and installed on one edge of the cloth sleeve body, and the inner end of the interface block is connected with a temperature sensing line and a heating line; heat generation and temperature sensation are separately controlled, and the multi-section temperature control is realized by the mode; the cloth sleeve body is made of waterproofing materials, the appearance of the cloth sleeve body can be cleaned by water scrubbing with simple operation. With regard to particular use, the pad can be used for warming and preserving heat of the waist, the neck, hands, legs and many other parts of a human body, can be used for the partial hot compress of the human body, has auxiliary effects on treating damp diseases, arthritis, scapulohumeral periarthritis and lumbar intervertebral disc protrusion and has the function of automatic temperature control.

Description

technical field [0001] The invention relates to the technical field of heating pads, in particular to a separately controlled heating pad. Background technique [0002] With the continuous improvement of people's living standards, people have invented heating pads using the principle of electric energy heating. The heating pads are easy to carry and take heat, so they have been widely used. A New Convenient and Practical Heating Pad" (Notice No. CN2568151Y) has such a design; it includes a jacket, a heating wire, an inner pad, several temperature switches and their controllers, and the heating wire and temperature switches are fixed on the inner pad. Inside, and the heating wire is connected in series with several temperature switches and connected to the controller. The design is simple in structure and has few components. Due to the continuous rotation during use, its structural strength is not enough, so it cannot guarantee a long service life; rate of occurrence, and p...
