The present invention has following good effect: fan of the present invention and be used for the base of fan, and it is simple in structure, is easy to batch production; In addition, this kind fan and be used for the base of fan, rotate and nonrotational process in, its overall appearance is all better.
Description of drawings
Figure l is the schematic representation of fan of the present invention.
Fig. 2 is the side view of the fan shown in the figure l.
Fig. 3 is the sectional view that A-the A line intercepts along the fan shown in the figure l.
Fig. 4 is the sectional view that B-the B line intercepts along fan shown in Figure 2.
Fig. 5 is that fan shown in Figure 1 is at the side view that turns to forward a certain position.
Fig. 6 is that fan shown in Figure 1 is rotating back to the side view of a certain position.
Embodiment
Figure l is the structural representation from the fan of the present invention 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 that B-the B line intercepts along fan shown in Figure 2 along the sectional view that A-the A line intercepts 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 the nozzle 2 that is arranged on the base 1; Base 1 comprises base portion 3 and the main body 4 that is positioned on the base portion 3; Main body 4 comprises main body 4a and lower 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 upper main body 4a can 9 rotate certain angle around the shaft.
It can also be seen that from Fig. 3 and Fig. 4 near the surface 13 that upper main body 4a is positioned at the lower end is Surface of Sphere, in the rotation process of upper main body 4a, upper main body 4a contacts with lower main body 4b by surperficial 13.In the present embodiment, upper main body 4a in rotation process all with lower 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 forward a certain position, 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 around the shaft 9 rotations of upper main body 4a, the air-out direction of nozzle 2 is changed at vertical plane, and in upper main body 4a rotation and nonrotational process, the lower end of upper main body 4a is positioned at the inside of lower main body 4b all the time.Under various use states, the overall appearance of fan is all better like this.
During apparatus of the present invention work, air enters in the main body 4 from the intake grill 5 that is arranged on the lower main body wall, the air flow-producing device that includes impeller chimney that is positioned at main body is converted to high pressure draught with the air that enters, this high pressure draught 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 the fan outside is entrainmented by opening 6 by the air-flow of launching from relief opening, consist of the forward total air flow of output from relief opening 8 air-flow of launching and the air-flow that is entrainmented, upper main body 4a 9 rotates around the shaft, make main body 4a with respect to lower main body 4b never oblique position tilt to oblique position, can change the orientation of the air-flow that nozzle 2 exports, to satisfy user's different requirements.
