[0003] For example, the patent with announcement number CN211876295U discloses a fresh air and air conditioning mixed air supply system, which includes a first air supply pipe, a second air supply pipe is arranged on one side of the first air supply pipe, a positioning retaining ring is fixedly installed on the first air supply pipe and the second air supply pipe, a locking sleeve is movably sleeved on the first air supply pipe and the second air supply pipe, a same air supply pipe connecting pipe is movably installed on one end of the first air supply pipe and the second air supply pipe close to each other, a filter screen installation port is opened on one side of the air supply pipe connecting pipe, and a filter screen installation port is fixedly installed in the filter screen installation port The net fixing ring makes the pull ring contact with the fixing groove on the connecting block, and presses the U-shaped locking handle downward to squeeze the sealing ring and the inner wall of the air supply duct connecting pipe, which can achieve a good sealing effect.

However, the device only has the functions of quick disassembly and filtering and cannot be adjusted according to different work requirements. For this reason, we propose a low-energy air supply device powered by a fresh air air conditioner. Utility Model Content
