Oxygen generating device

An oxygen generating device, comprising:

• a housing comprising a first sidewall and a second sidewall;
• a device chamber disposed within the housing and provided with a second side plate adjacent to the second sidewall;
• a compressor chamber disposed within the housing, wherein the compressor chamber internally accommodates a compressor and is located below the device chamber and in communication with the device chamber;
• an air intake module disposed on the first sidewall, wherein the air intake module is configured to introduce a cooling airflow into the housing and to supply air to the compressor;
• a cooling air duct comprising a first air inlet, a first air duct, a second air duct, and a second air inlet, wherein the first air inlet is disposed on the air intake module for introducing the cooling airflow, the first air duct is connected to the first air inlet and located between a top wall of the housing and a top plate of the device chamber, the second air duct is connected to the first air duct and located between the second sidewall and the second side plate, and the second air inlet is provided on the second side plate and configured to introduce the cooling airflow from the second air duct into the device chamber;
• and
• an exhaust silencing device disposed at a bottom of the compressor chamber, wherein the exhaust silencing device internally forms an exhaust silencing chamber, a silencing air inlet is disposed at a top of the exhaust silencing device to communicate the compressor chamber with the exhaust silencing chamber, and a silencing air outlet is disposed on a bottom of the exhaust silencing device to discharge airflow from the exhaust silencing chamber out of the oxygen generating device.
