Abstract: The present invention provides a brush wheel typed nebulizer, comprising: a drive device; a spiral pump, including a body, an outer sleeve, in which the outer periphery of the body is installed with at least a helicoid member closely attached to an inner sleeve having a flow opening inside the outer sleeve; a brush wheel, configured with multiple implant holes and having brush hairs forming at least a ditch; a sleeve lid, on which a notch is configured in correspondence with the end of the brush hair, and an inner bulge acting conjunctively with the end of the brush hair and having multiple guide grooves. With such a design, it is possible to fling off the highly viscous liquid attached on the brush hair to create atomized liquid of extremely tiny microdrops.
