Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of portable oxygen generators, and in particular relates to a portable oxygen generator. Background Art
[0002] Currently, there is a portable oxygen concentrator for elderly people who need medical care or in plateau areas. The user carries the oxygen concentrator on his body and uses a connecting tube to inhale the oxygen separated by the oxygen concentrator into the nasal cavity to achieve the adsorption of rich oxygen, ensure the blood oxygen content in the body, and it is convenient for use in a variety of places.
[0003] At present, in the use of portable oxygen concentrators, it is necessary to use them in a state where the molecular sieve is not saturated, and the molecular sieve is one of the main structures of the oxygen concentrator. The principle of molecular sieve oxygen production is based on the characteristics of gas adsorption and desorption. Generally speaking, molecular sieves have a strong affinity and can adsorb certain specific gas molecules on their surface. When oxygen and nitrogen in the air pass through the molecular sieve, nitrogen molecules are larger than oxygen molecules and are easily adsorbed by the molecular sieve, while oxygen is relatively less adsorbed. When the pressure is reduced, the molecular sieve releases the adsorbed helium to obtain an oxygen-rich airflow. During use, the molecular sieve needs to be replaced regularly. During the replacement, the operator first removes the outer shell of the oxygen concentrator, and removes the cylinder cover, pressure spring and filter cotton containing the molecular sieve in turn, and then dumps the molecular sieve and replaces it with a new one.
[0004] In the prior art, when replacing the molecular sieve of the oxygen generator, there are the following disadvantages: 1. When loading new molecular sieves into the placement cylinder, the operator needs to pour the molecular sieves while knocking on the cylinder wall to ensure that the molecular sieves are loaded densely. This step needs to be repeated. After pouring a certain thickness, a certain knocking is performed. During the entire replacement process, multiple knockings are required, which reduces the loading efficiency of the molecular sieve. At the same time, the operator cannot ensure the knocking strength. Too much force will damage the cylinder wall, and too little force will not ensure the compaction effect between the molecular sieves.
[0005] 2. After replacing the molecular sieve, the operator installs the filter cotton and the pressure spring into the placement cylinder in turn, and then tightens the cylinder cover with bolts. When tightening the cylinder cover, the stress of the pressure spring needs to be resisted to shrink the pressure spring, so that the installation requires a certain amount of force to press the cylinder cover, and the bolts need to be installed diagonally. This installation is inefficient and cumbersome, which brings inconvenience to the operator and the oxygen concentrator. Summary of the invention
