Description

Technical Field

[0001] This application relates to the field of electric blanket technology, specifically a fireproof electric blanket. Background Technology

[0002] An electric blanket, also known as an electric mattress, is a contact-type electric heating appliance. It incorporates specially made, high-insulation soft-cord heating elements woven or sewn into the blanket in a serpentine pattern. When powered on, it generates heat and is mainly used to raise the temperature inside the blanket while people sleep. It can also be used to dehumidify bedding. It consumes little electricity, has adjustable temperature, is convenient to use, and is widely used. It has a history of over 100 years.

[0003] An existing patent (publication number: CN220493170U) discloses an electric blanket, relating to the field of home textile technology. Its key technical features include a front blanket surface and a back blanket surface, with heating wires positioned between them. The heating wires are arranged in a serpentine pattern, and both ends of the heating wires are electrically connected to a control switch. Non-woven adhesive tape is provided at both ends of the heating wires to fix them to the back blanket surface. The surface of the back blanket surface is woven with fixing parts for allowing the heating wires to pass through and for limiting their position. This invention, through weaving, forms fixing parts on the back blanket surface to accommodate and limit the heating wires. This allows the heating wires to be fixed immediately after being inserted in a serpentine pattern, eliminating the need for manual sewing and saving production steps. Furthermore, the waterproof sleeve around the heating wires prevents sweat and other liquids from seeping into the electric blanket, which could cause leakage, thus ensuring the safety of the electric blanket during use.

[0004] The above-mentioned document can prevent sweat and other liquids from seeping into the electric blanket during use, which could cause leakage of electricity in the heating wire. However, its overall fire resistance is poor, and it lacks overheat protection and fire prevention capabilities. Utility Model Content

[0015] Through the above methods, the combination of graphene and textile fibers can be used to develop fabrics with multiple functions such as heat storage and warmth retention, light absorption and heat generation, far-infrared emission, waterproofing, moisture permeability, antibacterial and bacteriostatic properties, moisture absorption and wicking, and antistatic properties.

[0016] Furthermore, the first protective sleeve is made of polytetrafluoroethylene.

[0017] Through the above scheme, polytetrafluoroethylene exhibits excellent corrosion resistance, insulation properties, and high-temperature resistance, thereby improving the insulation of the heating wire body.

[0019] Through the above solutions, polyurethane exhibits high electrical insulation properties, wear resistance, and heat resistance, thereby improving its overall fire resistance.

[0020] Furthermore, the third protective sleeve is made of polyethylene.

[0021] Through the above method, polyethylene has good electrical insulation properties and heat resistance, and the cost is relatively low.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This fireproof electric blanket improves overall fire resistance and flame retardancy by combining a first protective layer and a second protective layer. By filling the hose with organic fire-retardant material, a chemical reaction occurs at high temperatures, releasing non-flammable gases, thereby diluting the concentration of flammable gases, reducing the combustion temperature, achieving flame retardancy, and thus improving overall fire resistance.
