Airway structure and corresponding oxygen generator using same

Abstract

The invention provides an airway structure and a corresponding oxygen generator using the same. The airway structure includes an outer shell body, an inner shell body, an air guiding member and a fanassembly, wherein air inlet holes are formed in the side surface of the outer shell body, the inner shell body is arranged in the outer shell body, and airflow space is formed between the outer wall of the outer shell body and the inner wall of the inner shell body; the airflow space is divided into an airflow channel by a muffler assembly, an air inlet is formed in the inner shell body, and the air guiding member is disposed outside a first casing; and one end of an air guiding cavity of the air guiding member communicates with the inner cavity of the inner shell body, the other end communicates with the outside, and a fan assembly is disposed in the air guiding cavity, and is used for accelerating discharge of the air. According to the airway structure, the inner shell body is arranged in the outer shell body, and the airflow space is divided into the airflow channel by the muffler assembly, so that the air is prevented from channeling, and noise is reduced; and at the same time, theair is also discharged through the air guiding member, and the heat dissipation efficiency is high.

Description

technical field [0001] The invention relates to the field of oxygen generators, in particular to an airway structure and a corresponding oxygen generator. Background technique [0002] Oxygen is a necessary substance for people to survive. It plays an important role in medical first aid or rehabilitation. Oxygen generator is a machine that uses air separation technology to produce oxygen. Power, press the air into the molecular sieve, so as to separate the nitrogen and oxygen in the air to obtain oxygen, the whole oxygen production process is a physical adsorption process, no chemical reaction, no pollution to the environment. [0003] Among them, the compressor of the oxygen generator in the prior art will generate heat during the working process. At the same time, because the volume of many oxygen generators is getting smaller and smaller, and the heat dissipation is not good, the temperature is easy to rise and the product is easy to burn out. The problem is, in addition...
