The invention discloses a
fire protection self-rescue
respirator, and belongs to the field of fie protection survival equipment. The
fire protection self-rescue
respirator comprises an expiration tube, an inspiration tube, a
breathing mask, an
oxygen reaction cavity, a cooling cavity, a storage cavity and a
water storage cavity. Both the inspiration tube and the
oxygen reaction cavity are arrangedin the cooling cavity, the
oxygen reaction cavity is a spiral thin tube, the upper end of the oxygen reaction cavity is connected with the expiration tube, KO2 is stored in the storage cavity, the bottom of the storage cavity communicates with the side where the upper end of the oxygen reaction cavity is located, and a feed adjusting mechanism is arranged at the communicating position. The lowerend of the oxygen reaction cavity communicates with the
water storage cavity, one side of the
water storage cavity is provided with a
water supply pipe connected to the side where the upper end of theoxygen reaction cavity is located, and the
water supply pipe is provided with a small water pump. By means of the
fire protection self-rescue
respirator, the supply condition of oxygen reaction raw materials in an oxygen reaction tank can be controlled, the CO2 quantity inspired during inspiration can be reduced, the oxygen inspiration effect for a user can be ensured, the O2 output is adjustableand controllable, the
cooling effect of O2 can be optimized, application functions are more perfect, and the practical value is high.
