An electronic cigarette includes a power supply device, an atomizer, a liquid storage structure, a fluid transportation device, a casing and a mouthpiece. The atomizer includes an electric heater and a liquid conduit. The electric heater is disposed around liquid conduit. The liquid storage structure includes a liquid container for storing cigarette liquid. The fluid transportation device includes an input channel in communication with the liquid container and an output channel in communication with the liquid conduit. The cigarette liquid is transferred to the liquid conduit through the fluid transportation device at a certain amount. Consequently, an atomized vapor is generated. The casing has an inlet in communication with the atomizer through an airflow chamber. The inlet and the airflow chamber form an airflow path for an airflow to pass through. The mouthpiece is located at an end of the casing and in communication with the airflow path.

A diaphragm valve includes a valve body defining a fluid passageway, a diaphragm assembled with the valve body, and an annular metal valve seat disposed on the valve body surrounding the fluid passageway, the valve seat defining an inverted frustoconical seat sealing surface for sealing against the diaphragm when the diaphragm is in a closed position.

A first on-off valve (2) and a second on-off valve (3) each are a two-port valve. A first passage block (5) is provided with a first on-off valve-corresponding inflow passage (11) and a first on-off valve-corresponding outflow passage (12). A second passage block (6) is provided with a second on-off valve-corresponding inflow passage (14) and a second on-off valve-corresponding outflow passage (15). The second on-off valve-corresponding outflow passage (15) is in communication with an upstream side portion of the first on-off valve-corresponding outflow passage (12) via a communicating passage (13) formed in the first passage block (5). An orifice (20) is provided between the second on-off valve-corresponding outflow passage (15) and the communicating passage (13).
