▎ 摘　　要

NOVELTY - The element has graphene heating sheet group (1), connecting lead (2), temperature protection switch (4) and protective sleeve (5). The connecting lead is provided with an inter-chip connecting lead and a power supply connecting lead (3). The graphene heating sheets have the same power density. The multiple graphene heating pieces are connected in series or in parallel through sheet connecting wires. The temperature protection switches are located on the graphene heating piece. The thermistor switch is connected in a series with the graphene heat sheet group. The protective sleeve is provided with a sheet connection wire and a thermistor. One end of the thermistor is led out to the outside of the protective sleeve through the power supply connection lead. USE - Graphene heating element for smart toilet seat cushion. ADVANTAGE - The rated voltage, rated power, and external dimensions can be customized to meet the requirements of toilet seats of different shapes and sizes. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic view of graphene heating element for smart toilet seat cushion. (Drawing includes non-English language text).
