AI Technical Summary
Existing one-way valves have long valve bodies, which prevent the blades from opening fully, affecting airflow and increasing material costs.
The design employs multiple blades, with the blade width slightly larger than the distance between the rotating shafts. The rotating shafts are parallel and perpendicular to the long axis of the elliptical airflow channel. The blades open under the thrust of the airflow to achieve a fully open state, thus shortening the valve body length.
It achieves full opening of the airflow channel, reduces valve body length and material costs, and improves airflow and versatility.

Abstract
Claims
1. A one-way valve for air flow comprising a valve body, characterised in that: The valve body is a pipe. One end of the valve body extends outward to form an annular flange plate. Several mounting holes are arranged in a spaced array on the annular flange plate. The other end of the valve body extends inward to form an annular connecting plate. An airflow channel is formed between the annular connecting plates. Several connecting seats are arranged at intervals on both sides of the annular connecting plate inside the valve body. The connecting seats on both sides correspond one to one. A rotating shaft is rotatably arranged between two corresponding connecting seats. One of the rotating shafts is located at the end of the annular connecting plate. Each rotating shaft is provided with a blade. One end of the blade is fixedly connected to the rotating shaft. The other end of the blade extends to the end of the annular connecting plate or the adjacent connecting shaft. When all the blades are closed, the airflow channel is blocked.
2. A one-way valve according to claim 1, wherein: The airflow channel formed by the annular connecting plate has an elliptical cross-sectional shape, all connecting shafts are parallel, and the connecting shafts are perpendicular to the major axis of the ellipse of the airflow channel, with one of the rotating shafts located at the end of the major axis of the ellipse.
3. A one-way valve according to claim 1 or 2, characterised in that: All blades have the same width, and the width of each blade is slightly greater than the distance between two adjacent shafts.
