1. The chemical oxygen generator receives the reaction of chemical oxygen generator to the field chemical nitrogen generator to produce oxygen. It can be used only with an oxygen generator and oxygen generator. The domestic oxygen generator of this oxygen making example is expensive. It is necessary to continuously purchase oxygen making agent to make oxygen.

2、电子制氧机接纳的是将氛围中的氧气在溶液中通过氧化及还原制氧机析出氧气的要领，由于其耗电量大，易孕生其他有害气体，利用寿命短、操纵贫苦并且代价昂贵等缺点，如今厂家已经很少生产这种范例的制氧机。从制氧机原理来看，应该是差的一种范例。

2. The electronic oxygen generator accepts the key to release oxygen from the atmosphere in the solution through oxidation and reduction. Due to its large power consumption, easy to breed other harmful gases, short service life, poor operation and high cost, manufacturers have rarely produced this kind of oxygen generator. From the principle of oxygen generator, it should be an example of poor performance.

3、富氧膜制氧机是利用高分子膜的通透性网络氛围中的氧气，氮气，从而制取氧气的。不必要任何添加剂，也无需加水，能上电源，就可以吸氧。缺点便是孕生的氧气浓度只有百分之30，只能做一样通常的家庭氧保健，不克不及用来氧疗。

3. Oxygen enriched membrane oxygen generator uses the permeability of polymer membrane to remove nitrogen from the oxygen in the network atmosphere, so as to produce oxygen. There is no need for any additives, and there is no need to add water. If you can power on, you can absorb oxygen. The disadvantage is that the oxygen concentration of pregnancy is only 30%, which can only do the same common family oxygen health care, and can not be used for oxygen therapy.

4、分子筛制氧机接纳分子筛的吸附性能，通过物理原理，以大排量无油压缩机为动力，把氛围中的氮气与氧气举行分散，高浓度的氧气。

4. The molecular sieve oxygen generator accepts the adsorption performance of molecular sieve, and uses the large displacement oil-free compressor as the power through the physical principle to disperse the nitrogen and oxygen in the atmosphere to produce high concentration oxygen.
