The invention discloses a self-inflating anti-drowning swim ring. Compressed air pockets are arranged on the left side and the right side of the self-inflating anti-drowning swim ring; a locking device is arranged at the back end of the self-inflating anti-drowning swim ring; a sealed area is formed between the two compressed air pockets at the front end; a circuit control system is placed in the sealed area; two square aluminum air cylinders are fixed in front of the sealed area; an inflating valve is arranged between the air cylinders; and a rebreather suction nozzle is connected in front of the valve. The suction nozzle can be taken off after being rotated for 90 DEG; the inflating valve is opened after the suction nozzle is taken off; and the air cylinders begin to rapidly inflate the air pockets. Meanwhile, when a water pressure sensor detects that the water pressure reaches a set maximum value, the inflating valve is automatically opened to inflate the air pockets. The self-inflating anti-drowning swim ring disclosed by the invention is advantaged in that the self-inflating anti-drowning swim ring is convenient to wear and almost has no influence on swinging; and the self-inflating anti-drowning swim ring has a self-saving function due to being provided with inflating equipment and breathing equipment.
