一种瓦斯报警矿灯
摘要：
一种瓦斯报警矿灯，利用原矿灯的蓄电池为电源在保持原矿灯各种性能的基础上，增加了报警性能。报警电路用微型元件组装在一块环形电路板上，然后用环氧树脂封固，装在原矿灯头内，在原开关轴下方增设一个复位开关，能使照明和报警电路齐通，或报警电路断照明电路通，或报警和照明电路齐断，该瓦斯报警矿灯，使用和维护方便，重量轻，耗电少，在照明、报警电路齐通时能工作11小时。
摘要（英）：

The utility model relates to a gas alarm miner's lamp. The gas alarm miner's lamp utilizes the accumulator of the original miner's lamp as the power source on the basis of the preservation of various performances of the original miner's lamp, and is additionally provided with the alarm performance. An alarm circuit is assembled on a circular circuit board by the microelement, is sealed by the epoxy resin, and is arranged on the original miner's lamp. The lower part of the original switch shaft is additionally provided with a reset switch. The reset switch causes that the illumination circuit and the alarm circuit are connected simultaneously, or the alarm circuit is disconnected and the illumination circuit connected, or the alarm circuit and the illumination circuit are disconnected simultaneously. The utility model has the advantages of convenient operation, light weight and less power consumption, and works for 11 hours when the illumination circuit and the alarm circuit are connected simultaneously.
