Description

technical field [0001] The invention relates to the field of oxygen generators, in particular to a filter detection and maintenance device for a molecular sieve oxygen generator and the molecular sieve oxygen generator. Background technique [0002] Zeolite is the adsorption material of PSA molecular sieve oxygen generator, and it is also a very expensive consumable in oxygen generator. It needs to be replaced regularly. The life of zeolite is mainly determined by three factors: dust, humidity and temperature. Among them, dust has a great impact on the life of zeolite. During the use of the PSA oxygen generator, the dust in the air will be attached to the molecular sieve, thereby reducing the adsorption capacity, which will shorten the life of the zeolite, so there is a filter at the air intake end of the PSA molecular sieve oxygen generator, the purpose is to filter dust particles in the air.

Problems solved by technology

[0002] Zeolite is the adsorption material of PSA molecular sieve oxygen generator, and it is also a very expensive consumable in oxygen generator. It needs to be replaced regularly. The life of zeolite is mainly determined by dust, humidity and temperature Three major factors determine that dust has a great impact on the life of zeolite. During the use of PSA oxygen generator, the dust in the air will be attached to the molecular sieve, thereby reducing the adsorption capacity, which will shorten the life of zeolite. Therefore, PSA molecular sieve The air intake end of the oxygen machine has a filter, the purpose is to filter out the dust particles in the air

[0003]The filters at the intake end of the PSA molecular sieve oxygen generator are all disposable, and the replacement cycle is relatively short, which is a high-consumption consumable. The replacement cycle depends on the use environment. If there are many air dust particles in the use environment, the replacement cycle is very short, and if there are few air dust particles in the use environment, the replacement or cleaning cycle is relatively long

[0004]However, the existing PSA molecular sieve oxygen generator does not remind users that the dust particles in the environment are too high, which will affect the life of the molecular sieve oxygen generator; and , and will not detect the effectiveness of the dust filter, or alarm to remind the user to replace the filter. Once the filter is damaged or fails, it will cause zeolite loss and bring large economic losses

[0005]In addition, the existing PSA molecular sieve oxygen generator does not have the function of maintenance and automatic cleaning of the filter; the side of the filter intake is easy to accumulate dust After a long time, a large number of dust particles in the accumulated dust penetrate or adhere to the filter, which greatly reduces the life of the filter and increases the user's use cost
