FLAMEPROOF ELECTRONIC DEVICE

原文（中国語）

This disclosure is directed to a flameproof electronic device having a housing, an electronic assembly, and a thermal-expandable structure. The housing has a pair of vents. The electronic assembly is accommodated in the housing, at least a part of the electronic assembly is spaced from the housing to enclose a flow channel between the electronic component and an internal surface of the housing, and the flow channel communicates with the vent. The thermal-expandable structure covers the internal surface of the housing or an external surface of the electronic assembly. The heat-expandable structure expands to block the flow channel when being heated to greater than or equal to a predetermined temperature.
