Patent ID: 8336398

Claim:
A flow monitoring pipe connection, comprising: a main body; an inner sleeve mounted in the main body and having a first end formed with a receiving chamber, a second end formed with a flow channel and a mediate portion provided with a separation wall connected between the receiving chamber and the flow channel; a water inlet connector mounted on a first end of the main body and connected to the receiving chamber of the inner sleeve; a water outlet connector mounted on a second end of the main body and connected to the flow channel of the inner sleeve; a circuit board mounted on the main body; a control panel mounted on the main body and aligning with the circuit board; at least one battery mounted on the main body and electrically connected with the circuit board by at least one electric wire to supply an electric power to the circuit board; a cover mounted on the main body to support the battery; a magnetically activated detector mounted on the separation wall of the inner sleeve and electrically connected with the circuit board to transmit a detected signal to the circuit board; an impeller rotatably mounted in the receiving chamber of the inner sleeve and disposed between the separation wall of the inner sleeve and the water inlet connector; and a magnetic member mounted on the impeller to rotate in concert with the impeller and movable to align with the detector; wherein the circuit board has a surface provided with a display and a control switch; the control panel has a surface provided with a window aligning with the display of the circuit board and a push button abutting the control switch of the circuit board; the separation wall of the inner sleeve has a periphery formed with a plurality of connecting holes connected between the receiving chamber and the flow channel and has a central portion formed with a shaft hole; the water inlet connector has an end portion having a periphery formed with a plurality of connecting bores and having a central portion formed with a shaft bore; the impeller has a periphery formed with a plurality of conducting holes connected between the connecting holes of the separation wall and the connecting bores of the water inlet connector; the impeller has a central portion provided with a rotation shaft having a first end rotatably mounted in the shaft hole of the separation wall and a second end rotatably mounted in the shaft bore of the water inlet connector.
