Description

Technical Field

[0001] This utility model relates to the field of electric heating comb technology, specifically an electric heating comb with a display screen. Background Technology

[0002] A heated comb is a personal care appliance with both drying and heating functions, primarily used for hair styling and care. It typically includes a comb plate that can be electrically heated to generate hot air, helping to quickly dry hair and create hairstyles. When using a heated comb, care should be taken not to overheat it to avoid damaging the hair, and it should be used under the guidance and advice of the manufacturer.

[0003] Because electric heated combs typically contain electronic components, cleaning them may not be as convenient as cleaning traditional combs. Traditional electric heated combs are extremely inconvenient to clean, requiring users to be extra careful to avoid water or cosmetics entering the circuitry. This invention reduces damage to internal electronic components by further disassembling and cleaning the comb teeth. A retractable structure is used inside the handle to reduce the risk of overheating during use. A touchscreen LED display screen is used to observe information such as the current temperature, working status, and set temperature. Therefore, we propose an electric heated comb with a display screen. Summary of the Invention
