Oxygen uptake pipeline device for oxygen-enriched treadmill

The invention provides an oxygen uptake pipeline device for an oxygen-enriched treadmill, which comprises a treadmill main body, an oxygen generator mounted on the treadmill main body, and an oxygen uptake pipeline interface for conveying oxygen generated by the oxygen generator to the oxygen uptake pipeline device, the oxygen inhalation pipeline device comprises a wearing fixing part, an oxygen inhalation opening and a breather pipe used for conveying oxygen from an oxygen inhalation pipeline connector to the oxygen inhalation opening, and is characterized in that the breather pipe comprises a telescopic hose part, and the telescopic hose part is configured to be in an elongated state when the telescopic hose part is subjected to a pulling force; and when the pulling force is removed, the telescopic hose part is in a shortened state due to the elasticity of the telescopic hose part. When a body builder wears the oxygen uptake pipeline device to run, unsmooth ventilation or running influence caused by winding
