in some embodiments, the fan 100 further includes an air outlet fan 130, the conditioning fan 140 and the airflow conditioning assembly 120 are disposed in the first air duct 112a, the air outlet fan 130 is disposed in the second air duct 112b, and the conditioning fan 140 is mainly configured to enable external air to enter the first air duct 112a, and at least one of heating, filtering and humidifying the air in the first air duct 112a by the airflow conditioning assembly 120. The air processed by the air flow adjusting assembly 120 enters the second air duct 112b under the action of the air outlet fan 130 and is blown out from the first air outlet 113 b.

The adjusting fan 140 is mainly used for introducing external air into the first air duct 112a, so that the air entering the first air duct 112a can pass through the airflow adjusting assembly 120 to be adjusted at a certain flow rate, the flow rate of the air after being adjusted can be partially attenuated, under the action of the air outlet fan 130, the air in the first air duct 112a enters the second air duct 112b and is blown out from the first air outlet 113b after being energized by the air outlet fan 130, the air outlet distance and the air outlet quantity of the whole fan 100 are improved, and accordingly the air feeling of a user is improved.

In this embodiment of the present application, the first air duct 112a and the second air duct 112b separate the adjusting function from the air outlet function, and the adjusting fan 140 mainly serves to introduce the external air into the first air duct 112a, so that the air entering the first air duct 112a has a certain flow rate and can be adjusted by the air flow adjusting assembly 120 without other external forces. The air flow rate of the air after passing through the air flow adjusting assembly 120 is lost, under the action of the air outlet fan 130, the air in the first air channel 112a enters the second air channel 112b, the air flow rate and the air outlet quantity of the air are improved through the air outlet fan 130, so that the air blown out from the first air outlet 113b has the flow rate, and the air outlet distance and the air outlet quantity are improved.
