Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generators, and particularly relates to an oxygen generator facilitating the loading and unloading of a filter screen. Background Art

[0002] At present, oxygen generators are more and more widely used. During the use of an oxygen generator, air cooling and heat dissipation are required for the oxygen generator. During the heat dissipation process of the oxygen generator, air needs to be inhaled from the outside. After dust and other impurities in the air enter the oxygen generator, the heat dissipation effect inside the oxygen generator will be affected, and noise is easily generated. Therefore, a filter screen is usually arranged at the air inlet of the oxygen generator to filter impurities.

[0003] However, the filter screen on the existing oxygen generator is integrally arranged on the oxygen generator or arranged inside the oxygen generator. It is not easy to take out the filter screen from the oxygen generator without disassembling the oxygen generator, and the loading and unloading of the filter screen are inconvenient.
