The air outlet device provided by the invention comprises an air duct provided with a first passing opening; the power assembly is arranged in the air duct and comprises fan blades and a power piece which are connected, and the power piece is suitable for driving the fan blades to rotate in the opposite first rotating direction or the second rotating direction; the first net cover is arranged at one end of the air duct, is arranged corresponding to the air outlet direction when the fan blades are in the first rotating direction and comprises a first grid area which is arranged in a fan ring or ring shape, a grid structure on the first grid area is obliquely arranged in the first rotating direction, and the corresponding inclination angle between the grid structure and the air outlet direction of the air duct is beta; and the corresponding inclination angle beta of each grid structure on the first grid area is gradually increased along the first rotation direction, and beta is greater than 0 and less than or equal to 30 degrees. According to tests, after the arrangement mode is adopted, the wind scattering range is widened, meanwhile, the wind resistance of outlet wind passing through the first net cover is reduced, the influence of the wind speed and the wind quantity of the outlet wind is small, and the defects that in the prior art, when a grid structure on the outer side of a circulating fan achieves the wind scattering function, the wind resistance is too large, and the wind feeling of the outlet wind is influenced are effectively overcome.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to an air outlet device. Background technique [0002] Compared with the floor fan, the circulation fan has added structures such as turbine blades and diffuser air ducts, which can let the wind blow out in a spiral shape along a certain direction. With the stirring of the fan blades, a spiral columnar wind can finally be formed, and its wind speed is high. , Long air supply distance, more suitable for circulating indoor air, more and more favored by consumers. [0003] The high-speed spiral blowing of the circulation fan, while the air supply is concentrated, also reduces the air outlet range of the circulation fan, which affects the user's experience. In the prior art, the grille structure used for air outlet on the outside of the fan can be adjusted to block the part The air outlet duct diffuses the air, but it will greatly increase the wind resistance of the air outlet and reduce ...
