All other embodiments, which can be obtained by a person skilled in the art without any inventive effort, based on the embodiments provided by the present utility model, shall still fall within the scope of protection of the present utility model.
It should be noted that, in the description of the present utility model, terms such as "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships, which are based on the directions or positional relationships shown in the drawings, are merely for convenience of description, and do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Further, it should also be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements.

Further, the oxygen consumption switching device 320 is configured such that when one of the first outlet 3215 and the second outlet 3216 is shielded by the first oxygen consumption valve 322, the other is opened.

For example, a valve for controlling opening and closing of each of the first inlet 3213, the second inlet 3214, the first outlet 3215, and the second outlet 3216 is provided. For another example, the inlet chamber 3211 and the outlet chamber 3212 are configured as one chamber, and only so that only a portion of the gas within the oxygen-consuming housing 321 flows through the air regulating device 200.

The air conditioning principle of the air conditioning space 101 in the first embodiment of the present utility model will be described with reference to fig. 2 and 3.
When the conditioned space 101 needs to have its oxygen content reduced, the control device 300 shifts to the first control attitude. Specifically, oxygen-enriched valve 312 is caused to block first oxygen-enriched outlet 3112 and to open second oxygen-enriched outlet 3113; causing first oxygen consuming valve 322 to open first inlet 3213 and block second inlet 3214; causing the second oxygen consuming valve 323 to block the first outlet 3215 and open the second outlet 3216. The blower 400 is then energized to cause the blower 400 to drive the air to circulate between the conditioned space 101 and the oxygen consuming cavity 212. At the same time, the air conditioning apparatus 200 is energized such that the cathode membrane assembly 220 consumes oxygen in the oxygen consuming chamber 212 through an electrochemical reaction and generates oxygen at the anode plate 230. In this process, oxygen generated by the air conditioner 200 is discharged to the outside through the oxygen-enriched switching device 310.
When the air-conditioned space 101 needs to be increased in oxygen content, the control apparatus 300 shifts to the second control posture. Specifically, oxygen-enriched valve 312 is caused to open first oxygen-enriched outlet 3112 and to block second oxygen-enriched outlet 3113; causing first oxygen consuming valve 322 to block first inlet 3213 and open second inlet 3214; causing the second oxygen consuming valve 323 to open the first outlet 3215 and to block the second outlet 3216. Then, the blower 400 is energized to cause the blower 400 to drive the outside air into and out of the oxygen consuming cavity 212.
