Oxygen generation system with ultralow leakage point dehydration function

The invention discloses an oxygen generation system with ultralow leakage point dehydration, and particularly relates to the technical field of oxygen generation systems, the oxygen generation system comprises an oxygen generation outer tank, a tank cover is fixedly mounted at the top end of the oxygen generation outer tank, and an inner cylinder base is arranged at the bottom of the inner side of the oxygen generation outer tank. A gas control mechanism is used in cooperation, gas enters a gas control outer pipe through a gas inlet end, the gas pressure in the gas control outer pipe is increased, a gas control bottom frame is driven to vertically move upwards in the gas control outer pipe, a plurality of gas control top cylinders are driven to move upwards, the tops of the gas control top cylinders are separated from gas control through grooves, a plurality of exhaust through holes are formed in dehydration adsorbents, and gas control springs are extruded; and gas is guided into the pretreatment cavity throu
