Graphene conductive non-woven fabric replaces traditional circuits on electric blankets mainly through the following methods:
Firstly. Structure and Connection Method
1. Heating element integration: Graphene conductive non-woven fabric is used as the heating layer to replace the alloy resistance wire and other circuit structures in traditional electric blankets. During the manufacturing process, graphene conductive non-woven fabric is combined with insulating fabric, etc. For instance, graphene paste is coated on a soft substrate (such as polyester fiber non-woven fabric), and then combined with conductive materials like copper (for example, copper wires are fixed on both sides of the graphene heating sheet) to form an integrated heating unit. There is no need for the serpentine wiring like traditional circuits. Heat is generated through the inherent conductive and heating properties of the non-woven fabric.
2. Simplified circuit connection: Traditional circuits require complex wiring to connect resistance wires into a loop. Graphene conductive non-woven fabric can be led out through simple electrodes (such as the copper wires mentioned above), connecting both sides of the non-woven fabric or specific areas to power lines and control devices. Multiple graphene heating units (if zoned) can be connected to the circuit in parallel or series with wires, simplifying the wiring process and reducing line nodes Reduce the risk of malfunction.
Secondly, functional realization substitution
1. Heating and temperature control: Traditional circuits generate heat through resistance wires. Graphene conductive non-woven fabric generates heat by taking advantage of its excellent electrical conductivity and electrothermal conversion characteristics, and can also control temperature more precisely. Temperature sensors can be set up in the non-woven fabric zones, in combination with control devices (including transformers, zone switches, etc.), to control the temperature of different areas (chest and abdomen, lower limbs) separately, replacing the traditional single circuit or simple zone temperature control. This results in a faster response, more uniform temperature control, and avoids local overheating or overcooling.
2. Safety performance optimization: Traditional circuit resistance wires have the risks of breakage, short circuit, leakage and fire. Graphene conductive non-woven fabric is resistant to bending and has good stability, and is less likely to break due to folding and other reasons. Some can be powered at low voltage (such as 36V, 12V), which is much lower than the traditional 220V and safer. It can also be combined with insulating cloth and fire-retardant materials to enhance insulation and fire resistance performance, and replace traditional line safety guarantee methods in terms of materials and structure.
Thirdly. Changes in production and usage processes
1. Production and manufacturing: Traditional circuits require the weaving and sewing of resistance wires into the blanket body, which is a complex process. Graphene conductive non-woven fabric can be first made into heating sheets (bonded inside insulating fabric, etc.) and used as a single component to be spliced with the anti-slip layer, decorative layer, etc. of electric blankets, simplifying the production process, improving production efficiency, and facilitating large-scale production.
2. Usage and maintenance: Traditional circuit electric blankets are difficult to clean and prone to damage due to the resistance wires being sensitive to breakage and water. Graphene conductive non-woven fabric electric blankets (some products) support overall machine washing. Due to their stable structure, water washing is less likely to affect the conductive and heat-generating performance, solving the problem of traditional circuit water washing and enhancing the convenience of use and product lifespan.
In simple terms, it takes advantage of the inherent characteristics of graphene conductive non-woven fabric, such as its conductive heat generation, easy integration, and excellent performance, to replace the wiring, heat generation, and temperature control functions of traditionalelectric blankets throughout the entire process from structure, function to production and use. It can also optimize safety and convenience performance.
