Abstract
A multi-purposed pneumatic tube connector, which is incorporated in a pneumatic system to create a second passageway, includes a main member and an electromagnetic valve. The main member has a main tunnel, a first tunnel, a second tunnel, an inter-tunnel, and a sub-tunnel. The second tunnel is normally communicated with the main tunnel. The inter-tunnel is communicated with the main tunnel, in which a control end of the electromagnetic valve is inserted. The inter-tunnel is communicated with the first tunnel through the sub-tunnel, and the electromagnetic valve may control the communication of the main tunnel and the first tunnel.
