Intelligent passive oxygen supply and humidifying device used for oxygen making machine and oxygen supply system

The invention discloses an intelligent passive oxygen supply and humidifying device used for an oxygen making machine and an oxygen supply system. The intelligent passive oxygen supply and humidifying device comprises a humidifying cup, a sealing cover, an air inlet duct, an air outlet pipe, a humidifying degree adjusting sleeve, a micro differential pressure sensor and a plurality of micropores used for distributing and humidifying oxygen; the humidifying cup is connected with the sealing cover; the top end of the air inlet duct is connected with an air inlet in the top part of the sealing cover; the lower part of the air inlet duct is immersed in humidifying fluid; the humidifying degree adjusting sleeve movably sleeves the outer side wall of the air inlet duct; the micropores are evenly formed in the air inlet duct; the air outlet pipe is arranged on the sealing cover. In such a manner, the utilization rate of the oxygen is increased by the intelligent passive oxygen supply and humidifying device used for
