111 side of axis is each provided with an impeller sets 12, so that cross flow fan 1 can be realized the bi-directional expansion of impeller sets 12, thus through-flow wind
Machine 1 has multiple operating modes, to user with multifarious selection, further increases user experience.Using extension shaft 112 to two
Moving impellers (122a and 122b) are limited and are oriented to, and can realize all right one way or the other movable vane in the case where not changing impeller blade
It is rotated synchronously between wheel (122a and 122b) and fixed impeller 121, guiding and limit effect are preferable.Using the second driving motor
Two moving impellers (122a and 122b) is shunk in 1231 band movable reels 1232 and the rotation of wirerope 1233, so that cross flow fan 1 is stretched
Compression process is smooth efficiently.The mode for using conducting slip ring 1211 to power for the second driving motor 1231 avoids the second driving electricity
Material winds and the case where breaking appearance, ensure that the service life of cross flow fan 1 caused by machine 1231 is powered by wire rod.
It should be noted that above-mentioned preferred embodiment is only intended to illustrate the principle of the present invention, it is not intended that in limit
Protection scope of the present invention processed.Under the premise of without departing from the principle of the invention, those skilled in the art can be to above-mentioned setting side
Formula is adjusted, so that the present invention can be suitable for more specifical application scenarios.
For example, in a kind of interchangeable embodiment, although what the first driving motor 11 in present embodiment used
It is dual-axle motor, but this set form is not unalterable, those skilled in the art can use the motor of other forms,
As long as the motor can drive impeller sets 12 to rotate.For example, in addition to dual-axle motor, it can also be using common uniaxial motor
As the first driving motor 11, but correspondingly, cross flow fan 1 is merely able to realize unilateral stretch.
For another example, in another alternatively embodiment, the quantity of moving impellers is not unalterable, art technology
