Electric air valve

The utility model discloses an electric air valve which comprises a shell, at least two fan blades and a synchronizing mechanism. The fan blades are rotationally connected to the shell; the synchronizing mechanism comprises an electric driving assembly and a parallel connecting rod mechanism, the synchronizing mechanism is installed on the shell, and the electric driving assembly can drive the fanblades to rotate synchronously through the parallel connecting rod mechanism; the parallel connecting rod mechanism comprises a linkage rod and at least two connecting rods, the connecting rods correspond to the fan blades in a one-to-one mode, one end of each connecting rod is fixedly connected with the corresponding fan blade, the other end of each connecting rod is movably connected with the linkage rod, and therefore a parallel double-crank mechanism can be formed between any two fan blades. By arranging the synchronizing mechanism comprising the electric driving assembly and the parallelconnecting rod mechanism,
