Described fan can be desk fan, can be wall fan, can be ceiling fan, can be flooring fan, can also be the fan of other type.
Description of drawings
Figure l is the front schematic view of fan of the present invention.
Fig. 2 is the side view of fan shown in Figure 1.
Fig. 3 is that the fan shown in the figure l is along the sectional view of A-A line intercepting.
Fig. 4 has showed second embodiment of fan of the present invention.
Fig. 5 has showed the 3rd embodiment of fan of the present invention.
Embodiment
Figure l is that Fig. 2 is the side view of the fan shown in the figure l from the schematic diagram of fan of the present invention of device forward observation, and Fig. 3 is the fan shown in the figure l along the sectional view that A-the A line intercepts.Can find out from Fig. 1 to Fig. 3, this fan comprises pedestal 1, is arranged on nozzle 2 and the globe 16 that is connected with nozzle on the pedestal 1; Pedestal 1 comprises base portion 3 and the main body 4 that is positioned on the base portion 3, and main body 4 can swing with respect to base portion 3; Main body 4 comprises the member that is used to form by the air-flow of described nozzle, described member comprises impeller chimney 11, is positioned at the impeller 12 of impeller chimney and the motor 13 of drives impeller rotary work, described main body 4 comprises main body 4a and the lower main body 4b with suction port 5, and upper main body 4a can slide with respect to lower main body 4b make its inclination; Nozzle 2 comprises inner passage 7, relief opening 8, rotatingshaft 17 and limits interior side body 9 and the outside housing 10 of inner passage 7 and relief opening 8, interior side body 9 comprises that guiding surface 14 that next-door neighbour's relief opening 8 arranges and next-door neighbour's guiding surface 14 arrange opens surface 15, nozzle 2 defines an opening 6 that is positioned at central authorities, and opening 6 has the axis X that is positioned at central part; Globe 16 is positioned at the middle and lower part of opening 6 and is rotationally connected with on the rotatingshaft 17.
In the present embodiment, opening 6 is roughly circle, and the height of its opening is about 250mm; Globe 16 is spherical, and its diameter is about 80mm; The distance of the underpart of the underpart of opening 6 and globe 16 is about 4mm.
During fan work of the present invention, air enters in the main body 4 from the suction port 5 on the main body 4, the member that is used to form the air-flow by described nozzle is converted to the higher air-flow of air pressure with the air that enters, this air-flow that has boosted is admitted in the inner passage 7 of nozzle 2, and the air-flow that inner passage 7 receives is by relief opening 8 emissions, air from the fan outside is entrainmented by opening 6 by the air-flow of launching from relief opening, consists of the forward total air flow of output from relief opening 8 air-flow of launching and the air-flow that is entrainmented; The globe 16 that is arranged in opening 6 moving axis 17 that can rotate under the drive of the air-flow of exporting rotates, so this globe 16 working state that can show geographic information and fan, has significantly improved the appreciation effect of whole fan.
