Figure l is the schematic diagram of the fan of the present invention from device forward observation, and Fig. 2 is the side view of fan shown in Fig. 1, and Fig. 3 shows the internal structure of fan shown in Fig. 1.In as can be seen from Fig. 1 to Fig. 3, the nozzle 1 that this kind of fan comprises pedestal 2 and arrange on the base 2; The base portion 10 that pedestal 2 comprises Base body 9 and is positioned at below Base body, Base body 9 has sidewall, and sidewall comprises air inlet 11, and air inlet 11 is the form of grid hole; Base body 9 comprises impeller chimney 8, is positioned at the motor 7 of the impeller 6 of impeller chimney and drives impeller rotary work, impeller 6 comprise general conical wheel hub, be connected to the multiple blade on wheel hub and be connected to the guard shield 15 of outer ledge of multiple blade, motor 7 is fixed on fixed block 14, fixed block 14 is connected with the diffuser 13 being positioned at impeller 6 downstream, and diffuser 13 is fixed on impeller chimney 8; Nozzle 1 comprises annular cavity 4, multiple relief opening 5, the chamber wall 3 limiting cavity 4 and relief opening 5 and the circular base slab 16 fixing with chamber wall 3, portion's chamber-separating wall of circular base slab 16 and chamber wall 3 integrally, annular cavity 4 is about axis X almost symmetry, annular cavity 4 is arranged around circular base slab 16, and relief opening 5 is positioned at the front end place of annular cavity 4; The chamber wall 3 of annular cavity 4 and circular base slab 16 are all made by transparent plexiglass; The diameter of this nozzle is about 300mm, and annular cavity 4 is about 100mm along the degree of depth in axis X direction, and the diameter of circular base slab is 250mm, thickness is 3mm; Relief opening 5 is slot-shaped relief opening, is about 1mm at the width in its outlet port, has fixed block 12 between two adjacent slits shape relief openings, can limit the width of relief opening like this and is fixed together by relative chamber wall.
In the present embodiment, the chamber wall 3 of annular cavity 4 is fixedly connected with circular base slab 16, defines firm structure and has distinctive aesthetic feeling; Because nozzle is made by transparent plexiglass, the stop of nozzle to natural light or artificial light is little, is conducive to user and carries out work or reading, also can show the internal structure of nozzle, be conducive to improving the attractive in appearance of fan further.
In the present embodiment, Base body 9 can swing by opposed base wall 10, Base body 9 comprises top base main body 9a and bottom base main body 9b, and top base main body 9a can slide into oblique position relative to bottom base main body 9b, such fan can in the horizontal direction or vertical direction regulate the orientation of air-out.
During this kind of fan work, be positioned at motor 7 drives impeller 6 rotary work of pedestal 2, air can be drawn into from the air inlet 11 be positioned at Base body 9, the air entered in Base body 9 is admitted in the annular cavity 4 of nozzle 1 after boosting, and spray by relief opening 5, from nozzle exterior air the air-flow that sprays by relief opening 5 entrainment, the air-flow be ejected and formed the total air flow penetrated forward from nozzle by the air-flow entrainmented.
Fig. 4 illustrates second embodiment of fan of the present invention.In the present embodiment, the chamber wall 3 of annular cavity 4 is also all made by transparent plexiglass with circular base slab 16.Easily find out from Fig. 4, the embodiment shown in the present embodiment to Fig. 1 is similar, and just the nozzle 1 of the present embodiment is provided with opaque red paint coating 18 on transparent circular base slab 16, thus defines a heart-shaped pattern.
Easy discovery, transparent host material arranges pattern or word etc. that opaque coating or translucent coating are easy to be formed various beauty, can form different visual effects.Its pattern or word can be diversified, and its change is apparent.
Fig. 5 illustrates the 3rd embodiment of fan of the present invention.In the present embodiment, the chamber wall 3 of annular cavity 4 is also all made by transparent plexiglass with circular base slab 16.Easily find out from Fig. 5, the embodiment shown in the present embodiment to Fig. 1 is also similar, just the nozzle 1 of the present embodiment be provided with on transparent circular base slab 16 four can be ventilative perforation 19.
Fig. 6 illustrates the 4th embodiment of fan of the present invention.In the present embodiment, the chamber wall 3 of annular cavity 4 is also all made by transparent plexiglass with circular base slab 16.Easily find out from Fig. 6, the embodiment shown in the present embodiment to Fig. 5 is similar, and just the nozzle 1 of the present embodiment is provided with the circular overlay 17 with four perforation 19 more than on transparent circular base slab 16.
In the present embodiment, circular base slab 16 also there is perforation 19(same on circular overlay 17 not shown in FIG.), this circular overlay 17 is connected with circular base slab 16 by rotary member 20, its rotary member 20 is the screw of band nut, so circular overlay 17 can opposing circular dunnage 16 rotate, thus the punch position on circular overlay 17 is changed relative to the punch position on circular base slab 16.When circular overlay 17 opposing circular dunnage 16 turns to a certain position, the air flow energy around nozzle is simultaneously through the perforation on circular base slab and the perforation on circular overlay; When circular overlay opposing circular dunnage turns to another location, the air-flow around nozzle can not simultaneously through the perforation on circular base slab and the perforation on circular overlay; So just can meet that dunnage is ventilated sometimes, nonventilated demand sometimes.
The present invention is not limited to the detailed description provided above.Those skilled in the art should be understood that deformation program of the present invention.
