| Zusammenfassung: | The utility model relates to a mining smoke sensor shell with a sealing platform, the mining smoke sensor shell manufactured by a casting process. An annular sealing platform is arranged on a circuit board fixing platform of a lower shell, the sealing platform is located above the smoke chamber, a U-shaped annular sealing ring sleeves the sealing platform, the circuit board is fixed on the circuit board fixing platform by an insulated terminal, and a smoke detector on the circuit board stretches to the smoke chamber. The sealing platform and the U-shaped annular seal ring on the sealing platform can effectively isolate the water vapor and corrosive gas to avoid the damage to the circuit board. |
