The invention relates to a safety helmet type individual escaping device for
gas explosion under a coalmine. The safety helmet type individual escaping device comprises an automatic
oxygen respirator, a safety helmet and a control part. A shell of the automatic
oxygen respirator is internally provided with an
oxygen cylinder, a filter, a pressure reducing valve, a one-way valve, a CO2 absorbent and the like; an
electromagnetic valve is connected with a leather bag; a gas duct is connected with the one-way valve which is connected a central blank
pipe in the CO2 absorbent; the leather bag is folded in a upper cover; and the bottom of the shell is enclosed. The safety helmet comprises a helmet body, a helmet lining, a
breather pipe, a
breather hose and the like; the
breather pipe is connected with an output pipe of the
electromagnetic valve on the
oxygen cylinder; and the breather hose is connected with a face contacting
mask. In the invention, an early warning
signal sent by an early warning network is received through a super-regenerative type
receiver module, and is decoded and amplified to an on-off controller to control the opening of the
electromagnetic valve which opens the
oxygen cylinder and is connected with the face contacting
mask through the breather pipe for supplying oxygen; meanwhile a
buzzer HA gives out an alarming sound; and a user manually pulls down the face contacting
mask to mouth and
nose positions. The invention gains precious time for escaping.
