The oxygen is discharged from the air pipe 2 at the top and enters the conduit 2. A small part of it enters the air pipe 2 through the pinhole on the balance valve and then enters the adsorption tower A8-10 to maintain the balance of the two adsorption towers. More oxygen passes through the one-way valve 8-14. And the three-way pipe, then enters the air pipe six to enter the bottom of the oxygen storage tank 8-5, and then flows upward from the air pipe three to enter the oxygen outlet pipe for use; after a period of time, the molecular sieve in the adsorption tower adsorbs more nitrogen, and the adsorption capacity decreases. At this time, the oxygen in the conduit two contains nitrogen, and the backflush valve 8-13 can be opened, and the oxygen enters the conduit one from the conduit two, and a part of the gas enters the upper part of the adsorption tower A8-10 through the air pipe one, and the nitrogen retained by the molecular sieve last use is backflushed. The backflush nitrogen enters the connecting pipe one 8-11 through the air pipe four, and then enters the nitrogen exhaust muffler 3 from the exhaust port through the outlet one of the four-way valve 8-13 for discharge. The generated oxygen is sent to the suction hood 2, sucked by the fan 17, and the mixed air enters the sterilization box 3, passes through the air purification and disinfection electric field, and the air purification and disinfection electric field is composed of a high-voltage electric wire mesh 18. The air first passes through here for voltage disinfection and sterilization, and then reaches the humidification water curtain 22. At this time, the water pump transports the pure water in the water tank 7 to the water diversion plate 20, and the water diversion plate 20 then diverts the pure water to the water curtain 22. The water curtain 22 is a honeycomb mesh structure. Water is dispersed from the upper water diversion trough 21 of the honeycomb mesh curtain and flows into the honeycomb mesh water curtain 22. The honeycomb mesh water curtain 22 is made of water-permeable paper. Wind force acts on the honeycomb mesh water curtain 22 to evaporate the water, and the moist wind is discharged from the air supply hole to humidify the room.

[0046] When the nitrogen exhaust silencer is in use, the gas to be exhausted by the molecular sieve enters the air intake pipe from the rubber hose and enters the air distribution chamber 8-24 in the shell, and is divided into two air flows and enters the air guide chamber 8-23 on both sides. In the air guide chamber 8-23, it passes through each air guide chamber in turn, and the flow rate is reduced by the baffle 8-20 in the air guide chamber, and then enters the tail gas chamber 8-22. In this process, the gas is discharged and silenced through the air outlet hole 8-18.

[0047] When installing and fixing, screw through the mounting hole in the mounting base of the nitrogen exhaust silencer, and then fix it on the outer side wall of the molecular sieve integrated tower.

[0048] In summary, the present invention integrates oxygen production, disinfection and humidification in one casing to reduce the volume. One part of the indoor air passes through the exhaust fan to the air purification and disinfection electric field, and the other part passes through the oxygen generator to separate the oxygen and then sends it to the exhaust fan. The mixed gas passes through the humidification water curtain and returns to the room, thereby achieving the effects of increasing the oxygen content, air sterilization and disinfection, and air humidification. In particular, it has multiple effects compared with air bacteria purification, plateau dry oxygen supplementation, chronic disease oxygen supplementation and indoor humidification.
