[0002] In modern building environments, fresh air systems are key devices for ensuring indoor air quality, and their performance and reliability directly affect the comfort and health of living or working spaces. The fan module, as the core component of the fresh air system, is responsible for driving airflow and achieving the exchange and circulation of indoor and outdoor air. However, the designs of fresh air systems widely used in the current market generally face a technical challenge: the disassembly and assembly process of the fan module is complex and difficult to operate.

[0003] Traditional fresh air system designs often deeply integrate the fan module into the body, using welding or other connection methods that are difficult to release quickly. While this design ensures structural stability to a certain extent, it causes great inconvenience to technicians during routine maintenance, troubleshooting, or replacement and upgrade of the fan module. The disassembly and assembly process not only requires specialized tools and equipment but also consumes a lot of time and manpower, increasing maintenance costs and reducing work efficiency. Utility Model Content

[0012] As a further improvement and optimization of this solution, each of the air cavities has at least one rear support on its inner wall, and each of the fan modules has at least one rear support leg on the side away from the inspection port. The side of the rear support leg away from the front support is longitudinally limited and matched with the rear support.

[0013] As a further improvement and optimization of this solution, multiple reinforcing plates are formed between the fan module and the rear support leg and the front support leg, respectively.

[0014] As a further improvement and optimization of this solution, the front bracket / rear bracket is located on the top inner wall / bottom inner wall of the air cavity.

[0015] As a further improvement and optimization of this solution, the rear bracket forms a socket, the rear support leg is inserted into the socket, and is longitudinally limited to the inner wall of the socket.
