1. An air cleaning apparatus for a ventilation seat, the air cleaning apparatus comprising:
a housing including a flow path configured to allow air to move therethrough;
a photocatalyst located in the flow path of the housing and rotatably coupled to the housing to be rotatable with respect to the housing, the photocatalyst being integrally coupled to a rotating plate;
an ultraviolet light emitting diode (UV LED) fixed at the housing and configured to emit light of a light source toward the photocatalyst when power is supplied to the UV LED;
a motor coupled to the rotating plate and configured to generate power for rotating the rotating plate; and
a controller configured to control operation of the motor and power supply to the UV LED,
wherein the controller is configured to control the operation of the motor and the power supply to the UV LED by use of ignition-on or off signals of a vehicle, door lock and open signals, a signal of a seating sensor provided in the ventilation seat, and a voltage signal of a battery.
