Abstract
The utility model relates to a secondary air intake device for purifying tail gas of a motorcycle. A one-way valve and a flow control valve are integrated in a seat body. A T-shaped airflow channel is arranged in the seat body. The one-way valve is formed from a reed and a limiting plate fixed on one end of a base arranged at the lower part of the seat body. A stop valve is formed from a platform and a sealing cover arranged on an air path in the seat body. A slide shaft is inserted into a right slide way, and the sealing cover is fixedly arranged on the left end of the sliding shaft. The sealing cover and the platform can keep a distance by a spring between the sealing cover and the seat body. The right air path is closed by a membrane, and the right air path and the membrane are closed by a membrane chamber cover to form the flow control valve. An air intake pipe and an air filter of the device are connected. A water outlet pipe is connected with an air draining port. A flow control pipe is communicated with an engine intake path. When an air draining system is in negative pressure, a one-way valve is opened. Inversely, the one-way valve is closed. When a motorcycle is decelerated rapidly, the inner part of the diaphragm chamber is in negative pressure. The membrane drives the slide shaft to move right to close the left air path. No air enters the one-way valve, and the exposure phenomenon is eliminated. The device has the advantages of short flow path of air flow between two valves, large flow capacity, sensitive response, high reliability, small size and low cost.
