The invention relates to an electric vehicle charger with fireproof performance, which comprises a shell with an inner cavity, a circuit board and a fan are arranged in the inner cavity, the circuit board is provided with a socket, the fan is provided with a first power supply plug, the first power supply plug of the fan is inserted into the socket, and one end of the shell is provided with a vent hole opposite to the fan. A controller, a sealing assembly and an air exhaust assembly are further included, a flame sensor is arranged in the inner cavity, the controller is used for receiving a flame signal of the flame sensor to control the sealing assembly to block the air vent, and the air exhaust assembly is used for conducting air exhaust operation on the inner cavity after the air vent is blocked. If the interior of the battery car charger is on fire, the flame sensor detects a flame signal and then transmits the flame signal to the controller, the controller controls the sealing assembly to block the ventilation opening, at the moment, no oxygen for combustion is supplemented in the inner cavity, meanwhile, the air exhaust assembly conducts air exhaust operation on the inner cavity, the oxygen content in the inner cavity can be further reduced, and the service life of the battery car charger is prolonged. And flame extinguishing is accelerated.
本申请涉及一种具有防火性能的电动车充电器,包括带有内腔的壳体,内腔内安装有电路板和风扇,电路板上设有插口,风扇上具有第一供电插头,风扇的第一供电插头插接在插口上,壳体的一端开设有正对风扇的通气口,还包括控制器、密封组件和抽气组件,内腔内设有火焰传感器,控制器用于接收火焰传感器的火焰信号,来控制密封组件封堵通气口,抽气组件用于在通气孔封堵后对内腔进行抽气操作。如果电瓶车充电器内部发生着火,火焰传感器检测到火焰信号后传递给控制器,控制器控制密封组件封堵通气口,此时内腔不会再有可供燃烧的氧气补充,同时抽气组件再对内腔进行抽气操作,能够进一步减小内腔中的氧气含量,加快火焰熄灭。
