AI Technical Summary
Existing connection boxes have limited functionality and poor applicability when adapting to different types of air handling units, which increases manufacturing costs and difficulty.
Design a connecting box with a first state and a second state. In the first state, it provides a filter installation position to filter air. In the second state, it achieves thermal insulation through insulation components. The outer contour and air cavity size remain unchanged in both states. It has universal parts to adapt to different scenarios.
The application and functionality of the connection box have been improved, manufacturing costs and manufacturing difficulty have been reduced, and air cleanliness and transportation efficiency have been improved at the same time.
