The invention provides a toilet flushing device suitable for a railway vehicle and a working method. The toilet flushing device comprises a first air supply device, a first electromagnetic valve, a vent valve, an external exhaust port, a water supply device, a water inlet valve, a water tank, a liquid level sensor, a control panel, a flushing button, a second air supply device, a second electromagnetic valve, a flushing valve and a toilet. The control panel is connected with the first electromagnetic valve, the water inlet valve, the liquid level sensor, the flushing button and the second electromagnetic valve; the first electromagnetic valve is installed between the air supply device and the water tank and connected through an air pipe. The water inlet valve is installed between the water supply device and the water tank and connected through a water pipe. The second electromagnetic valve is mounted between the second air supply device and the flushing valve and is connected through an air pipe; the flushing valve is arranged between the water tank and the toilet stool and is connected through a water pipe; the vent valve is installed between the air supply device and the water tank, and the vehicle exterior exhaust port is connected with the water tank through the vent valve. Automatic water replenishing of the water supercharging device can be achieved, and the problem that water flows for a long time due to valve clamping stagnation is avoided.
