AI Technical Summary
Technical Problem
The filter of existing oxygen concentrators is prone to seal failure and gas leakage when repeatedly disassembled and cleaned, affecting the sealing performance.
Method used
The system uses an I-shaped cylindrical sleeve and a gas distribution device inside the sleeve to filter oxygen through the filter screen. It also uses an adjustment device and a flow guiding component to change the airflow direction, thereby achieving the cleaning and sealing of the filter screen.
Benefits of technology
It achieves effective oxygen filtration and filter cleaning, prevents dust from entering the airway, maintains the device's airtightness, and avoids gas leakage.

Abstract
This invention belongs to the field of medical device technology, and specifically discloses an air filtration device for an oxygen concentrator, including a sleeve. The top and bottom of the sleeve are connected to end tubes. A cap is fixed to the top of the sleeve, and the inner side of the cap is fixed to the outer surface of the end tubes. A drain pipe is connected to one side of the cap. An I-shaped sleeve is rotatably installed inside the sleeve, and its top and bottom are slidably and sealingly fitted to the inner top and bottom surfaces of the sleeve. In this invention, oxygen generated by the oxygen concentrator is filtered through a filter opening on a metal cover inside the sleeve. An air distribution device inside the sleeve can change the direction of internal airflow. An adjustment device can change the working state of the air distribution device, controlling its filtration of oxygen and cleaning of the filter opening. A flow guiding component can guide the airflow and also close the mounting slot to prevent dust from falling into the airway when cleaning the filter opening.
