AI Technical Summary

Technical Problem

The air intake filters of the existing oxygen generator are external, which leads to an increase in the overall volume of the oxygen generator, poor appearance quality, and the grille structure at the air intake port is not conducive to appearance optimization.

Method used

A hidden air intake structure is adopted, and a hidden air intake port is formed by setting an air intake groove and an air intake cover on the outer shell of the oxygen generator, and a first filter is provided in the air intake cavity, so that the appearance quality is optimized while space occupation is reduced.

Benefits of technology

It improves the appearance quality of the oxygen generator, has a compact structure, reduces space occupation, enhances market competitiveness, and ensures airflow cleanliness through filters.

Abstract

The utility model discloses an oxygen generator air inlet structure and an oxygen generator, and the oxygen generator air inlet structure comprises an air inlet groove arranged on an outer shell of the oxygen generator; the air inlet cover covers the open end of the air inlet groove; the air inlet cavity is defined by the air inlet groove and the air inlet cover; the first filtering piece is arranged in the air inlet cavity; a first air inlet used for leading in external air is formed between the air inlet cover and the groove wall of the air inlet groove in a surrounding mode. And an opening through which gas in the gas inlet cavity flows out is formed in the groove bottom of the gas inlet groove. The air inlet groove and the air inlet cover are arranged, so that a hidden air inlet structure is formed, and the appearance quality of the oxygen generator can be improved; and the air inlet structure is directly arranged in the shell, so that the structure is compact, the occupied space is reduced, and the market competitiveness is improved. The first filtering piece is arranged in the air inlet cavity and used for filtering air flowing in from the outside, dust and other impurities carried in the air are prevented from entering the shell, and the cleanliness of airflow entering the shell is guaranteed.
