Embodiment
As shown in Figure 1 to Figure 3, another kind of electric fan of the present utility model comprises supply air system 1, support 2, base 3, framework 6, first positive stop 4, supply air system 1 is installed on the base 3 by support 2, its medium-height trestle 2 upwards stretches out from the both sides of supply air system 1 from base 3, is connected from both sides by framework 6 and supply air system 1; Framework 2 is a loop configuration, the link 7 that distributes by bilateral symmetry be installed in support 2 in; Link 7 and support 2 Spielpassung, with framework 6 secure fit, framework 6 can be done rotation up and down for the axle center by link 7 in support 2; First positive stop 4, being used for is being axle center spacing when realizing rotation with link 7, and an end is fixed on the edge of framework 6, and the other end is vertical protruding and axially vertical with framework 6, and the spacing of external part and support 2 is not more than the width of this external part;
Supply air system 1 comprises the fan page or leaf 11 of housing 10, motor driven, is installed in the framework 6;
When supply air system 1 when being a plurality of, be installed in the inside of framework 6 by the link 9 that is symmetrically distributed up and down; Link 9 and framework 6 Spielpassung, with supply air system 1 secure fit, supply air system 1 can link 9 be done left rotation and right rotation for the axle center in framework 6; When supply air system 1 and framework 6 were connected to one, supply air system 1 can be that rotation is up and down done in the axle center in support 2 with link 9 with framework 6;
Simultaneously, be provided with second positive stop 8 on the circumferential edge of housing 10, being used in supply air system 1 is axle center spacing when carrying out left rotation and right rotation with link 9; Second positive stop, 8 one ends are fixed on the housing 10, and the other end is vertical protruding and axially vertical with housing 10, and the height of external part is not less than the height of framework 6, and are not more than the width of this external part with the spacing of framework 6;
First positive stop 4, second positive stop 8 can the be separately positioned on position corresponding with link 7, link 9;
Be to improve the configuration performance of link, be provided with rubber column 13 in framework 6 and link 7 corresponding positions, rubber column 22 is connected cooperation with link 7; Housing 10 and link 9 corresponding positions are provided with rubber column 14, and rubber column 14 is connected cooperation with link 9.
Link 5,7,9 can be bearing pin or structures such as rivet or adjustable bolt.
As Fig. 1, Fig. 2, shown in Figure 3, the supply air system 1 of this fan has three:
A plurality of independent agencies that will have said structure are assembled on the same foot rest, promptly three supply air system 1a, 1b, 1c are connected with framework 6a, 6b, 6c by link 9a, 9b, 9c respectively, be connected with support 2 respectively by framework 6a, 6b, 6c again, framework 6a, 6b, 6c are connected with support 2 by link 7a, 7b, 7c, and forming a desk fan has three independent supply air systems; These three independent supply air system 1a, 1b, 1c can do about up and down 145 ° separately separately and face upward and bow, about about 145 ° of spinning movements, by the control switch control that is installed on support or the base.
This fan spinfunction explanation:
By manual tune supply air system 1a, make it around link 9a to right rotation, when rotating about 145 °, the second positive stop 8a and framework 6a produce constructive interference, and restriction supply air system 1a continues to constitute spacing to right rotation, make supply air system 1a be parked in this position, air-supply to the right;
Manual tune supply air system 1b makes it around link 9b to anticlockwise, when rotating about 145 ° again, the second positive stop 8b and framework 6b produce constructive interference, and restriction supply air system 1b continues to form spacing to anticlockwise, supply air system 1b is stopped, to the left air-supply in this position;
At last, manual tune supply air system 1c makes it to rotate up around link 9c again, rotate about 145 when spending, the first positive stop 4c and framework 6c produce constructive interference, and restriction supply air system 1c continues to rotate up, form spacingly, supply air system 1c is stopped, and be tilted to air-supply.
If wish that lower position is strengthened air-supply can be rotated down supply air system, can realize air-supply more by force to lower position.
At this moment, air-supply in the scope about this fan has been realized about 270 °, the air-flow that each supply air system produces can not form the phase mutual interference, this air-supply is for constant, but compare with the electric fan of existing hunt, overcome the discontinuity of multi-direction air-supply, really realized multi-direction multi-angle air-supply.
