A misting fan includes a fan assembly including fan blades and a first electric motor for driving the fan blades to rotate; a body formed with a frame for supporting the fan assembly; and a nozzle disposed on the fan assembly and/or the body. The body is formed with a first accommodation cavity for water storage, and the first accommodation cavity is disposed around the fan assembly. In a circumferential direction, an angle of the first accommodation cavity around the fan assembly is greater than or equal to 180. The misting fan further includes a pump component for pumping water in the first accommodation cavity to the nozzle.

A turbine for a fluid-spraying device including a turbine body, and a rotor rotating a bowl relative to the body about an axis, the rotor being surrounded by the turbine body in a plane perpendicular to the common axis, the turbine body guiding the rotation of the rotor, the rotor being rotated by a stream of gas, the turbine body receiving the stream of gas at the outlet of the rotor, and delimiting at least one outlet duct configured to guide a first portion of the received stream into a space delimited in a plane perpendicular to the common axis by the bowl and a skirt.

A rotary atomizing coating device includes a main body including a rotary drive unit, and a bell cup attached to the rotary drive unit. The bell cup includes: a side surface portion extending toward a distal end in an axial direction of the rotary drive unit; a through hole configured to allow an inner surface and an outer surface of the side surface portion to communicate with each other and also configured to eject a coating material therethrough; and an outward protruding portion that is formed closer to the distal end in the axial direction than the through hole and protrudes more outward in a radial direction of an axis of the rotary drive unit than the side surface portion.
