Abstract

The invention relates to a safety protection device for electric appliance charging. A fireproof curtain is fixedly mounted on the side wall of a top plate of a U-shaped charging bracket through an arranged electromagnetic chuck; two parallel sliding rails are arranged at the lower end of a base, the base can slide along sliding rails through pulleys at the bottom end, the front ends and the rear ends of the sliding rails are connected through connecting rods, a spring fixing seat is arranged on the connecting rod at the front end, a pull rope fixing seat is arranged on the connecting rod at the rear end, and a spring fixer is arranged at the lower end of the base. A spring is installed between the spring fixing base and the spring fixing device, a metal pull rope is arranged between the spring fixing device and the pull rope fixing base, and a magnetic power-off trip is arranged between the metal pull rope and the spring fixing device. The design is scientific and reasonable, when the charging electric appliance is in short circuit or fire danger, fire extinguishing treatment can be conducted in the first time, the charging electric appliance is made to be far away from the charging power source, the larger fire risk is avoided, and the charging safety is improved.

Description

Technical field [0001] The present invention belongs to the technical field of electrical safety, relates to electrical charging apparatus, particularly to a charging electrical safety devices. Background technique [0002] With the development of intelligent, people's lives have entered the era of intelligent, also called intelligent life. Intelligent household appliances can be seen everywhere, such as intelligent robots, intelligent sweeping machines, smart phones and smart appliances and so on. [0003] Most of the smart appliances that need to be charged before use, so it can not avoid lengthy charging, when charging existing smart appliances are charged by a charger connected to the charging power outlet, did not make any protective measures . [0004] Since a long time charge, people can not always keep by the appliance; when the ambient temperature is high, the aging or overheating during charging, charging smart appliances such as short circuit or fire hazard will occur ...
