Technical Field
The invention relates to the field of flow dividers, in particular to a flow dividing structure and a bladeless fan.
Background
The existing bladeless fan generates airflow through the airflow generator, and the airflow is upwards and freely guided into the nozzle to be emitted outwards, so that the service life of the flow guide channel is easily shortened, and the airflow is unsmooth.
Accordingly, there is a need for a fan with a flow dividing structure and a bladeless fan to solve the above problems.
Disclosure of Invention
