In some alternative embodiments, as shown in fig. 7 to 9, a plurality of flow guiding channels 301 are provided on the annular exhaust hood 300, and the flow area of the inlet of each flow guiding channel 301 is the same as the flow area of the jet opening 201. Like this, under the condition that annular air-out cover 300 was installed and is used on air-conditioning outlet, the air current water conservancy diversion that water conservancy diversion passageway 301 erupted to efflux mouth 201, the air-out air current that drives the air conditioner through the air current that efflux mouth 201 erupted takes place to squint, because the flow area of the entry of water conservancy diversion passageway 301 is the same with the flow area of efflux mouth 201, the air current that efflux mouth 201 erupted can be unobstructed gets into in the water conservancy diversion passageway 301, thereby the change of the whole air-out of better drive air conditioner, and then make the air conditioner wholly have diversified air-out mode, satisfy people to the diversified demand of air-out mode.

Optionally, the inner annular surface 302 of the annular exhaust hood 300 is disposed in an inclined or arc shape, and the inner annular surface 302 thereof defines the trumpet-shaped channel 500. Like this, under the condition that annular goes out fan housing 300 and installs the use on the air outlet of air conditioner, the air current of air conditioner air outlet department flows out through annular play fan housing 300, goes out the interior anchor ring 302 of fan housing 300 through the annular and carries out the gathering water conservancy diversion to the air-out air current of air conditioner, and the interior anchor ring 302 of annular play fan housing 300 also can be to the air current water conservancy diversion that jet 201 erupted, and the air current that makes jet 201 erupt drives the air-out air current of air conditioner takes place the skew, improves the whole air-out effect of air conditioner.

Optionally, the trumpet channel 500 comprises: a wide opening 501 and a narrow opening 502. The annular air outlet cover 300 corresponding to the thick opening 501 is rotatably connected with the rotating part 200. Thus, the airflow at the air outlet of the air conditioner enters the trumpet-shaped channel 500 through the thick opening 501 and flows out through the thin opening 502 under the action of the gathering and guiding of the inner annular surface 302 of the annular air outlet cover 300, and the air outlet effect of the air conditioner is improved.

Optionally, the plurality of flow guiding channels 301 are disposed on the inner annular surface 302 of the annular exhaust hood 300 and are uniformly distributed along the inner annular surface 302 thereof. Like this, drive the rotatory fluidic in-process of efflux mouth 201 at rotating part 200, the air current that efflux mouth 201 jetted can be even get into water conservancy diversion passageway 301 in, drive air conditioner air-out air current through water conservancy diversion passageway 301 water conservancy diversion after the skew takes place, make the air conditioner whole have the air-out more even of diversified air-out mode.

Optionally, the flow guide channel 301 extends from a wide mouth 501 of the trumpet channel 500 to a narrow mouth 502 thereof. Like this, make water conservancy diversion passageway 301 can make the air current that jet opening 201 erupted from trumpet-shaped passageway 500 thick mouthful 501 department to thin mouthful 502 department water conservancy diversion, make the air current that jet opening 201 erupted can be better drive air conditioner air-out air current and take place the skew to the change of the whole air-out of better drive air conditioner, and then make the air conditioner whole have diversified air-out mode.

Optionally, the shape of the inlet of the flow guide channel 301 is the same as the shape of the jet orifice 201. Like this, the entry that makes water conservancy diversion passageway 301 also is fan ring shape setting, makes the flow area of water conservancy diversion passageway 301 entry the same with the flow area of efflux mouth 201, and the air current that efflux mouth 201 erupted can be unobstructed gets into in the water conservancy diversion passageway 301 to the change of the whole air-out of better drive air conditioner, and then make the air conditioner whole have diversified air-out mode, satisfy people to the diversified demand of air-out mode.

Optionally, four flow guide channels 301 are provided, and the radian of the corresponding fan-shaped annular structure at the inlet of the flow guide channel 301 is one fourth of pi. Like this, make four even the setting in the interior anchor ring 302 of annular air-out cover 300 of water conservancy diversion passageway 301, and the flow area of the entry of water conservancy diversion passageway 301 is moderate, the air current that jet orifice 201 erupted can unobstructed entry into water conservancy diversion passageway 301, when the rotary part 200 rotated the position of difference, jet orifice 201 and the water conservancy diversion passageway 301 intercommunication efflux of difference, can be according to the change jet position in user's position, thereby change the holistic air-out direction of air conditioner, make the air conditioner whole have manifold air-out mode.

Optionally, four diversion channels 301 are sequentially disposed on the inner annular surface 302 of the annular exhaust hood 300 at the positions corresponding to 12 o 'clock, 3 o' clock, 6 o 'clock and 9 o' clock. Like this, under the condition that this fluidic device installed the use on air-conditioning outlet, can make through the rotation of rotating part 200 according to user's position that jet 201 and 12 o ' clock, 3 o ' clock, one intercommunication in the water conservancy diversion passageway 301 in the position that 6 o ' clock and 9 o ' clock correspond, make the air-out air current orientation of air conditioner or reverse user's position skew, improved user's experience.

Alternatively, the flow area of the flow guide passage 301 gradually decreases from one end communicating with the jet port 201 to the other end. Like this, dynamic pressure turns into the static pressure gradually when making the air current that jet 201 erupted flow through water conservancy diversion passageway 301, and the dynamic pressure increase of the air current that flows through water conservancy diversion passageway 301 has improved the air supply distance, and the air current velocity of flow improves, easily drives air conditioner air-out air current and takes place the skew to the change of the whole air-out of better drive air conditioner, and then make the air conditioner whole have diversified air-out mode, satisfy people to the diversified demand of air-out mode.

Alternatively, the flow area of the flow guide channel 301 decreases from the wide opening 501 of the trumpet channel 500 to the narrow opening 502 thereof. Like this, make the flow area of water conservancy diversion passageway 301 reduce to its thin mouthful 502 department by the thick mouth 501 department of tubaeform passageway 500 gradually, thereby dynamic pressure turns into the static pressure gradually when making the air current that jet 201 erupted flow through water conservancy diversion passageway 301, the dynamic pressure increase of the air current that flows through water conservancy diversion passageway 301, the air supply distance has been improved, and the air current velocity of flow improves, easily drive the air conditioner air-out air current and take place the skew, thereby the change of the whole air-out of better drive air conditioner, and then make the air conditioner wholly have diversified air-out mode, satisfy people to the diversified demand of air-out mode.
