Description
Technical field
The present invention relates to a kind of fan.Especially, but not in exclusive manner, the present invention relates to a kind of domestic fan, as family expenses desk fan, for increasing air circulation and Air Flow in indoor, office and other environment.
Background technique
Traditional domestic fan generally includes motor and is driven the one group of blade or the impeller that are rotated by motor.This group blade is usually located in cage, and this cage allows air stream to pass, but but stops human body to touch the blade of rotation.But in some cases, this kind of fan also exists human body and touches the danger of this group rotation blade.
On November 15th, 1949, U.S. Pat 2488467 discloses a kind of fan that does not expose fan blade, this kind of fan comprises pedestal and is arranged on the ring nozzle on pedestal, the fan blade that pedestal comprises motor and driven by motor, the fan blade of rotation provides air-flow to ring nozzle, this kind of ring nozzle comprise annular outer cover, be positioned at cavity, the relief opening of annular outer cover and be positioned at the opening of ring nozzle central part, is transported in cavity and is deflated mouthful spray from the air-flow of pedestal.This kind of fan provides comparatively uniform air-flow and improved the Security using.But the pedestal of this kind of fan is larger, in nozzle, the transmission loss of air-flow is larger.
Summary of the invention
The present invention aims to provide a kind of improved fan to overcome above-mentioned defect of the prior art.The object of the invention is to provide-the less and shapely fan of kind of air-flow transmission loss; Another object of the present invention is will provide a kind of can show the internal structure of nozzle and reduce the fan that light stops.
