High-efficiency minitype molecular sieve tank

Abstract

The invention discloses a high-efficiency minitype molecular sieve tank. An inner cylinder and a central gas pipe are embedded into the inside of an outer cylinder from outside to inside; the lower part of the outer cylinder is connected with an outer cylinder pedestal; the upper part of the outer cylinder pedestal is provided with a communicating groove, and the lower part is provided with a gas inlet which communicates with the communicating groove; an inner cylinder pedestal, which is fixedly connected with the inner cylinder, is embedded in the communicating groove; the top of the inner cylinder pedestal is provided with a filter tank, and the edge is provided with a filter gas hole; a gap between the outer cylinder and inner cylinder communicates with the communicating groove through the filter gas hole and outer cylinder pedestal; the lower end of the central gas pipe is fixed to the inside of a filter tub; the upper part of the outer cylinder is connected with an outer cylinder top cover; the outer cylinder top cover is provided with a gas outlet; the upper end of the central gas pipe is fixedly connected with the outer cylinder top cover; the upper part of the central gas pipe communicates with the gas outlet, and the lower part communicates with the filter tub; the inner cylinder and outer cylinder are respectively filled with a molecular sieve; the top of the molecular sieve is compacted by an internal gland; and a spring is arranged between the internal gland and the outer cylinder top cover. The high-efficiency minitype molecular sieve tank has the advantages of high oxygen production efficiency and small size, and is convenient to carry and easy to demount and remount.

Description

technical field [0001] The invention relates to the field of medical and health care equipment, and more specifically relates to a high-efficiency small molecular sieve tank. Background technique [0002] With the improvement of economic life, the awareness of environmental health has also been continuously improved. People have a deeper understanding of health care. Oxygen therapy and health care have become the health needs of more and more families. Some people with altitude sickness, the elderly or aerobic patients are more The most important thing is that it is necessary to supplement oxygen conveniently and quickly outdoors. [0003] However, most of the oxygen concentrators in the market cannot be carried around, and the noise is high. Portable oxygen concentrators need a lighter and more compact design and an efficient molecular sieve utilization structure, which requires portable oxygen concentrators to have small and efficient DC compressors. And an oxygen generat...

[0003] However, most of the oxygen concentrators in the market cannot be carried around, and the noise is high. Portable oxygen concentrators need a lighter and more compact design and an efficient molecular sieve utilization structure. This requires portable oxygen concentrators to have small and efficient DC compressors. And an oxygen generating unit with a miniaturized structure
