[0002] Fire doors are used to maintain the fire resistance integrity of fire escape routes and provide escape routes. Their purpose is to ensure that people escaping in the fire escape routes are protected from the threat of fire within a reasonable period of time, including blocking thick smoke and heat. Energy-saving electric door closers are door control products that use electric motors as drive devices to control the opening and closing of doors. They are energy-saving, environmentally friendly, intelligent, and convenient. They use sensors, controllers and other components to automate the opening and closing of doors, which not only improves the efficiency of door use, but also effectively saves energy consumption.
[0003] Some existing energy-saving electric door closers require continuous power supply to maintain the limit position when in the normally open state, which consumes a lot of power and increases the system load. In addition, in the event of an emergency fire, the corridor is usually powered off and lacks a backup light source for reminder function, which is more dangerous at night. Utility Model Content
