Abstract

The invention relates to the technical field of automobile manufacturing, in particular to a graphene electric heating defrosting hand-scraper. The graphene electric heating defrosting hand-scraper comprises a scraper handle, a scraper frame and a scraper head, wherein the scraper head comprises a soft scraper layer, a graphene heating layer and a liner layer, the scraper head is nested on the scraper frame, a heating electrode communicates with a storage battery in the scraper handle through a brush contact of the scraper head and a scraping contact of the scraper frame, and the hand-scraperscraper head is heated through the graphene heating layer; and a heating circuit is controlled by a control device arranged on the scraper handle, and the battery is charged by a charging device. According to the graphene electric heating defrosting hand-scraper, a graphene heating film in the scraper head is instantly heated to melt and remove frost on automobile glass, so that the graphene electric heating defrosting hand-scraper is simple, rapid and effective and is easy to replace and maintain, and people can drive conveniently in the morning in winter.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a graphene electric heating defrosting hand scraper. Background technique [0002] When the outdoor temperature is low in winter, the car glass is often covered with a layer of ice crystals. If you urgently need to go out to do errands in the morning, it will take a long time to melt the frost covering the glass through the slow heating of the car air conditioner, which is labor-intensive, fuel-intensive and time-consuming. In an emergency, people often use hot water to defrost, apply hot towels or scrape to defrost, and the use of hot water to defrost often causes the glass to break due to the sharp increase in temperature difference. Using hot towels to apply and wipe is not only very troublesome but also often Because the temperature is too low to repeatedly freeze, it is neither thorough nor convenient to use a scraper to defrost. People have been looking f...
