[0002] A fresh air machine is an effective air purification device that can circulate indoor air. On the one hand, it discharges the dirty air indoors outdoors, and on the other hand, it inputs the fresh air outdoors into the room after measures such as sterilization and filtration, so that the air in the room is fresh and clean at all times. The fresh air machine uses the fresh air convection technology to achieve convection of indoor air through independent air supply and air induction, so as to maximize the replacement of indoor air.
[0003] However, the air volume of the fresh air introduction device on the existing air duct machine cannot be adjusted, and its applicability is relatively low. Secondly, the filter screen on the general air duct machine is mostly installed inside the main unit of the air duct machine to filter impurities in the air such as dust and fluff. When the fresh air filter screen is used for too long, there will be situations such as clogging, so the filter screen needs to be replaced regularly to ensure the filtering effect. However, when replacing the fresh air filter screen, the main unit needs to be disassembled, and the filter screen is not easy to take out, making the replacement of the filter screen a difficult problem, time-consuming and laborious, and the replacement efficiency is low. For this reason, we propose a fresh air introduction device for efficient refrigeration to solve the above problems. Content of the Utility Model
