The present invention discloses an air-explosion type
underwater air efficient extraction device, comprising a
vaporization chamber arranged in a vertical direction, a tapered cover connected to the top of the
vaporization chamber, a gas collecting cover arranged above the tapered cover, a gas output
pipe connected to the top of the gas collecting cover, a
gas collecting tube connected to the gas output
pipe arranged in the gas collecting cover, air holes evenly arranged on the side wall of the
gas collecting tube, a gas collecting cover arranged at the bottom of the
gas collecting tube, and an air-explosion mechanism arranged on the
vaporization chamber; the air-explosion mechanism comprises a water inlet arranged on one side of the vaporization chamber, a water outlet arranged on the other side of the vaporization chamber directly opposite to the water inlet, a waterproof driving motor fixedly arranged on the side of the vaporization chamber, the driving motor connected to a driving shaft, and the driving shaft connected to a
propeller driving water to flow from the water inlet to the water outlet. Through the above arrangement, it can extract air from the water efficiently and quickly, thereby meeting the
oxygen demand of people working and living
underwater, thereby expanding the space for
human life.
