The fourth design of this application, on the basis that does not change the original structure of air conditioner, only can accomplish new trend and oxygen-enriched gas's input through setting up an air inlet adjusting device and switch, reduced manufacturing cost.

The fifth design of this application has set up filter equipment on air inlet unit 10 to filter the new trend that gets into indoorly, set up filter equipment in new trend pipeline 22, can reduce the filter screen area and can guarantee that outdoor new trend is whole to pass through filter equipment again simultaneously, have that the filter effect is good, advantage with low costs.

The sixth design of this application sets up the outside of HEPA filter screen 111, makes it be the ring-type, and the filter screen area reduces by a wide margin and can also guarantee that outdoor new trend is whole to flow through the HEPA filter screen simultaneously, has reduced manufacturing, use cost under the condition of guaranteeing the filter effect.

The seventh design of this application, the filtering action of just imitating filter screen and HEPA filter screen makes the new trend just filtered before getting into indoor set, has further reduced the indoor risk of pollutant entering.

The eighth concept of the present application, on the one hand, leads oxygen therapy pipeline 31 to new trend pipeline 22, has reduced oxygen therapy pipeline 31's length, and on the other hand is through setting up dehydrating unit at oxygen boosting output chamber 113 to this vapor that will carry in the oxygen-enriched gas gets rid of, thereby has ensured that oxygenation module 30 can last, the efficient is indoor transport clean oxygen-enriched gas.

The ninth idea of the present application is to dispose the dehumidifying device 16 in the oxygen-enriched output cavity 113 for dehumidifying the oxygen-enriched gas flowing through the oxygen-enriched output cavity 113, thereby avoiding the problems of mildewing and icing caused by water vapor in the oxygen pipeline 31.

The tenth idea of the present application is that the shape of the dehumidifying device 16 is a spiral structure, so that the contact area between the oxygen-enriched gas and the dehumidifying material can be increased as much as possible, and the dehumidifying efficiency can be improved.

In the eleventh aspect of the present invention, the heating body 17 is disposed in the oxygen-enriched output cavity 113 for heating the oxygen-enriched gas.

The twelfth concept of the present application, wear to establish heating member 17 in dehydrating unit 16, can make heating member 17 can carry out the even heating to dehydrating unit 16, avoid shortening its life because of the local thermal ageing who brings the 16 local positions of dehydrating unit because of the local heating is uneven.
