[0042] The embodiment also provides an adjusting method based on the diving gas proportioning adjusting device 100, which comprises the following steps: when the diver carries the breathing nozzle 8 to dive, the depth sensor 9 judges the diving depth according to the water pressure, and transmits the data to the controller 28, the oxygen concentration required at the current diving depth is calculated by an algorithm formula in the controller 28, the algorithm formula is: oxygen concentration x (diving depth / 10 + atmospheric pressure) x 100 = conventional diving oxygen partial pressure, and the conventional diving oxygen partial pressure is 160 kpa; the controller 28 controls the adjusting mechanism according to the oxygen concentration required at the current diving depth, drives the three-way proportional valve 5 to rotate, and then controls the oxygen concentration of the diving gas guided into the storage component 6.

[0046] Specifically, when diving, the pawl 27 is in contact with the ratchet wheel 26, at this time the transmission rod 19 can only rotate in one direction, that is, only the air hose 7 can be released, and the pawl 27 cooperates with the ratchet wheel 26 to prevent the transmission rod 19 from accidentally winding the air hose 7 when the diver is diving. When floating, the pawl 27 is separated from the ratchet wheel 26, at this time the rotation of the transmission rod 19 is no longer limited, and then the air hose 7 can be wound by rotating the transmission rod 19.
