The oxygen concentrator is a common oxygen collecting device, and the working principle of the oxygen concentrator is that a zeolite molecular sieve is used as an adsorbent, and nitrogen in air is adsorbed and released by utilizing the principles of pressurized adsorption and reduced pressure desorption, so that oxygen collection and concentration improvement are completed. The zeolite molecular sieve has super strong adsorption performance and strong adsorption performance because molecular attraction acts on a 'surface force' generated on the surface of a solid, when a fluid flows through the zeolite molecular sieve, some molecules in the fluid collide the surface of an adsorbent due to irregular movement, molecular concentration is generated on the surface, and the number of the molecules in the fluid is reduced to the purposes of separation and removal. Since the adsorption does not change chemically, the zeolite molecular sieve has the adsorption capacity as long as the molecules concentrated on the surface are tried to be driven away, and the process is the reverse process of the adsorption and is called a desorption or regeneration process. Zeolitic molecular sieves also have strong ion exchange properties, which refer to a process of compensating for cation exchange outside the framework. The pore size of zeolite molecular sieves can be changed by ion exchange to change their properties. After ion exchange, the number, size and position of cations are changed, for example, after high-valence cations exchange low-valence cations, the number of cations in the zeolite molecular sieve is reduced, and the position is always vacant, so that the pore diameter of the zeolite molecular sieve is enlarged; when the ions with larger radius exchange the ions with smaller radius, the holes are easily blocked to a certain extent, so that the effective aperture begins to be reduced.
