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

Abstract

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 the oxygen making machine and the oxygen supply system, disclosed by the invention, and power consumption, noise, size and the like of the oxygen making machine are further reduced; the intelligent passive oxygen supply and humidifying device further has the advantages of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of oxygen supply devices, in particular to an intelligent passive oxygen supply and humidification device for an oxygen generator and an oxygen supply system. Background technique [0002] At present, the oxygen generator or other oxygen supply adopts the continuous flow oxygen supply mode, and the oxygen supply is continuously supplied when the user breathes. If an ordinary pressure sensor is used to detect whether the user is inhaling, the humidification and oxygen supply cannot be achieved; and conventional humidification The cup cannot adjust the degree of humidification of the output oxygen. [0003] In the continuous oxygen supply mode, the volume and power consumption of the preparation are required to be large enough. For example, the minimum power consumption of 3L and 5L oxygen generators is 230W and 330W, the weight is about 15kg, and the noise is above 42dB; another example is the medical oxygen supply sys...

[0003] In the continuous oxygen supply mode, the volume and power consumption of the preparation are required to be large enough. For example, the minimum power consumption of 3L and 5L oxygen generators is 230W and 330W, the weight is about 15kg, and the noise is above 42dB; another example is the medical oxygen supply system, ordinary users After the oxygen supply is turned on, the oxygen will continue to be released regardless of whether the user is inhaling oxygen or not, resulting in a waste of resources; even if the pulse oxygen supply is achieved by the ordinary low-pressure detection method, it is still impossible to simultaneously detect the user's inhalation state and wetness. The purpose of oxygenation, the user can only inhale dry oxygen, poor experience
