Embodiment

Figure l is that Fig. 2 is the side view of the fan shown in figure l from the structural representation of the fan of the present invention of device forward observation, and Fig. 3 is the sectional view intercepting along A-A line of scheming the fan shown in l.From Fig. 1, Fig. 2 and Fig. 3, can find out, this fan comprises base 1 and is arranged on the nozzle 2 on base 1; Base 1 comprises base portion 3 and has the main body 4 of air flow-producing device; Described air flow-producing device comprises impeller chimney 16, is positioned at the impeller 17 of impeller chimney and the motor 18 of drives impeller rotary work; Main body 4 comprises main body 4a and lower main body 4b, and main body 4 comprises

shell

19a, 19b, and lower main body 4b comprises the intake grill 5 being arranged on shell 19b; Nozzle 2 comprises having annular inner passage 7 and relief opening 8, and nozzle 2 defines central opening 6.

With reference to figure 6 and Fig. 7, upper main body 4a also comprises that first housing 10, the first housings 10 with the first opening 11 are positioned at the underpart of main body 4a and fix with shell 19a; Lower main body 4b comprises that upper end portion and shell 19b that second housing 13, the second housings 13 with the second opening 14 are positioned at lower main body 4b fix, and lower main body 4b also comprises the noise reduction member 9 being connected with the second housing 13, and this noise reduction member is annular; Main body 4 also comprises for upper main body 4a is remained on to the interlocking structure on lower main body 4b, and this interlocking structure comprises two the first locking components 12 that are positioned on the first housing 10 and is positioned at two the second locking components 15 on the second housing 13; The first locking component 12 of this interlocking structure and the second locking component 13 can make main body 4a with respect to lower main body 4b slide make its never oblique position tilt to oblique position.

From Fig. 1, Fig. 2 and Fig. 3, can also see, upper main body 4a and lower main body 4b have outer surface, and when upper main body 4a is with respect to lower main body 4b during in oblique position not, the anastomosis part of described outer surface is substantially flush.

In the present embodiment, main body 4 can swing with respect to base portion 3, thereby can regulate the air-out orientation of fan.

Fig. 4 is that the fan shown in Fig. 1 is being tilted forward to the side view of a certain position, and Fig. 5 is that the fan shown in Fig. 1 is receding to the side view of a certain position.From Fig. 4 and Fig. 5, easily find out, upper main body 4a can make the air-out direction of nozzle 2 change on vertical plane after sliding with respect to lower main body 4b.

During apparatus of the present invention work, the intake grill 5 of air from shell 19b enters in main body 4, the air flow-producing device that comprises impeller that is positioned at main body is converted to by the air entering the air-flow that air pressure is higher, this air-flow having boosted is admitted in the inner passage 7 of nozzle 2, and the air-flow that inner passage 7 receives is launched by relief opening 8, air from fan outside is entrainmented by central opening 6 by the air-flow of launching from relief opening, the air-flow of launching from relief opening 8 forms the total air flow of output forward with the air-flow being entrainmented, upper main body 4a is with respect to the slip of lower main body 4b, can change the orientation of the air-flow that nozzle 2 exports, because main body 4 comprises noise reduction member 9, the noise that can effectively absorb or decay and produced by air flow-producing device.

Although shown and described and thought at present preferred embodiments of the invention, apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from scope of the present invention as defined in appended claims.
