The invention provides an aviation nozzle. The fixed end of a motor is connected with a drip-proof check valve. A spherical valve element connected with the liquid inlet end of a liquid flowing channel in a separable mode is arranged in a cavity. The spherical valve element is elastically connected with the other end of the cavity through a spring. A plurality of centrifugal fluted discs are arranged on the other side of the motor in a rotating mode. A conical face is arranged on a circular base of each centrifugal fluted disc. A plurality of etching grooves arranged along the bus are formed in the inner side of each conical face. A nut is fixed into each centrifugal fluted disc. The check valve is connected with a transfer tube which penetrates through the center of the motor and the bases of the centrifugal fluted discs. A transfer opening is formed in the portion, located in each centrifugal fluted disc, of the transfer tube. A solution switch can be controlled through pressure without installing electromagnetic valves, and the control steps are reduced and are convenient and easy; centrifugal fluted discs of different numbers and transfer tubes of different lengths can be selected according to demands to adjust the fogdrop size, the atomizing effect is good, and adjustability is high.
