1. A fan comprising: a body comprising at least one first air inlet and a fan motor unit for generating an airflow, wherein the fan motor unit comprises an impeller, a motor and an air-output three-way seat; and a nozzle connected to the body, wherein the nozzle is configured to receive the airflow from the body and emit the airflow, the nozzle comprises a nozzle body and at least one third air outlet, and the nozzle body is inverted U-shaped; wherein, the air-output three-way seat comprises at least one second air inlet located at an air-output side of the impeller, a first air outlet connected to the nozzle, a second air outlet connected to the nozzle, and an air-splitting wall body for splitting the airflow passing through the at least one second air inlet of the air-output three-way seat and then guiding the airflow to the first air outlet and the second air outlet, respectively, wherein, two ends of the nozzle body are connected to the first air outlet and the second air outlet, respectively; wherein, the airflow passes through an air-input shroud and the fan motor unit in sequence in a gravity direction, and then enters the nozzle, wherein within the nozzle, the airflow at least moves along a direction opposite to the gravity direction and then is emitted out of the nozzle; the at least one first air inlet of the body is located on an upper portion of the body in the gravity direction, the first and second air outlets of the body are located on a lower portion of the body in the gravity direction, the fan motor unit is located in an area between the at least one first air inlet of the body and the first and second air outlets of the body, a position of the fan motor unit overlaps a position of the nozzle in the gravity direction, the motor is located above the air-output three-way seat in the gravity direction, and an axis of the motor and an axis of the at least one first second air inlet extend in the gravity direction.
