Embodiment

Figure l is the structural representation from the fan of the utility model of device forward observation; Fig. 2 is the side view of the fan shown in the figure l; Fig. 3 is that Fig. 4 is the sectional view along the B-B line institute intercepting of fan shown in Figure 2 along the sectional view of the A-A line institute intercepting of the fan shown in the figure l.Can find out that from Fig. 1, Fig. 2, Fig. 3 and Fig. 4 this kind fan comprises base 1 and is arranged on the nozzle 2 on the base 1; Base 1 comprises base portion 3 and is positioned at the main body 4 on the base portion 3; Main body 4 comprises main body 4a and following main body 4b, and main body 4 comprises impeller chimney 10, is positioned at the impeller 11 of impeller chimney and the motor 12 of drives impeller rotation work; Nozzle 2 comprises inner passage 7, relief opening 8 with annular and about the opening 6 of axis X symmetry.

It can also be seen that from Fig. 2 and Fig. 4 base 1 also comprises the rotating shaft 9 that parallels with axis Y, rotating shaft 9 comprises first rotating shaft 9a and second rotating shaft 9b, and last main body 4a is 9 rotating certain angle around the shaft.

It can also be seen that from Fig. 3 and Fig. 4 near the surface 13 that last main body 4a is positioned at the lower end is the ball face, in the rotation process of last main body 4a, last main body 4a contacts with following main body 4b through surperficial 13.In the present embodiment, last main body 4a in rotation process all with following main body 4b fluid-tight engagement, its in the gap of junction point less than 1 millimeter.

Fig. 5 be fan shown in Figure 1 at the side view that turns to a certain position forward, Fig. 6 is that fan shown in Figure 1 is rotating back to the side view of a certain position.From Fig. 5 and Fig. 6, find out easily, after last main body 4a 9 rotations around the shaft, the air-out direction of nozzle 2 is changed on vertical plane, and in last main body 4a rotation and nonrotational process, the lower end of last main body 4a is positioned at the inside of main body 4b down all the time.Under various user modes, the overall appearance of fan is all better like this.

During the utility model work; Air gets in the main body 4 from the intake grill 5 that is arranged on down on the body wall; The air flow-producing device that includes impeller chimney that is positioned at main body converts the air that gets into into high pressure draught, and this high pressure draught is admitted in the inner passage 7 of nozzle 2, and the air communication that inner passage 7 is received is crossed relief opening 8 and launched; Entrainmented through opening 6 by the air-flow of launching from relief opening from the fan air outside; The air-flow of being launched from relief opening 8 constitutes the total air flow of output forward with the air-flow that is entrainmented, and last main body 4a 9 rotates around the shaft, make main body 4a with respect to following main body 4b never oblique position tilt to oblique position; Can change the orientation of the air-flow that nozzle 2 exported, to satisfy user's demands of different.

In the present embodiment, following main body 4b can swing around the rotating shaft that parallels with axis Z with respect to base portion 3, and promptly main body is swung with respect to base portion, and the air-out direction of nozzle 2 is changed on horizontal plane.

Although showed and described the embodiment who thinks preferred the utility model at present, obvious, those skilled in the art can carry out various changes and improvement, and does not deviate from the scope of the utility model that is limited appended claims.
