Optionally, the predetermined distance is less than or equal to one third of the radius of the bowl-shaped structure. Like this, predetermine the radial third that the distance is greater than the alms bowl shape structure and can lead to the air current that jet 300 jetted out and the air-out of air conditioner apart from being far away, and then reduced the influence of the air current that jet 300 jetted out to the air-conditioner air-out, lead to the air-conditioner air-out can not take place the skew along with the air current that jet 300 jetted out, reduce the holistic air-out effect of air-conditioner, consequently will predetermine the distance and set up to be less than or equal to alms bowl shape structure radial third, not only can make the air current that jet 300 jetted out and the air-out of air-conditioner more close, the air-conditioner air-out also can take place the skew along with the air current that jet 300 jetted out, improve the holistic air-out effect of air-conditioner, and enable to form certain angle between the air current that jet 300 jetted out and the air-out of air-conditioner, the change of the whole air-out angle of better drive, thereby make the air-conditioner wholly possess diversified air-out mode.

It will be appreciated that the predetermined distance is the distance between the circumference of the bowl-shaped structure and the jet opening 300.

Alternatively, the rotating part 200 includes: an air flow path 201. The air flow passage 201 is provided inside the rotary part 200, and has one end communicating with the jet flow channel 100 and the other end communicating with the jet orifice 300. Thus, the jet flow channel 100 is communicated with the jet orifice 300 through the airflow passage 201, a flow path is provided for airflow between the jet flow channel 100 and the jet orifice 300, airflow conveying is facilitated, and meanwhile airflow in the jet flow channel 100 can rapidly flow to the jet orifice 300, and airflow flowing efficiency is improved.

Alternatively, the airflow passage 201 is offset from the center of the rotating portion 200 toward the periphery. In this way, the inlet of the airflow passage 201 is arranged at the center of the rotating portion 200, the inlet of the airflow passage 201 and the airflow passage 201 are always kept on the same axis in the rotating process of the rotating portion 200, the rotating portion 200 and the airflow passage 201 can be stably communicated in the rotating process, the stability of airflow flowing is improved, the airflow passage 201 deviates from the center of the rotating portion 200 to the periphery, the outlet of the airflow passage 201 can be enabled to face the jet orifice 300, airflow in the airflow passage 201 can be stably conveyed to the jet orifice 300, and the airflow flowing efficiency and the air outlet efficiency of the jet orifice are improved.

Optionally, the flow area of the airflow channel 201 from the fluidic channel 100 to the fluidic port 300 gradually decreases. Like this, because airflow flow area reduces gradually, make the air current through airflow channel 201 convert the dynamic pressure into by the static pressure, promote the air current velocity of flow, improve the air-out speed of efflux mouth 300, and then promote the efflux effect to flow area reduces gradually, can produce the funnel effect, makes the air current velocity of flow grow, has further promoted the efflux effect.

Optionally, the maximum flow area of the airflow passage 201 is greater than or equal to 2 times its minimum flow area and less than or equal to 4 times its minimum flow area. Thus, when the maximum flow area of the airflow passage 201 is smaller than 2 times of the minimum flow area, the difference between the maximum flow area and the minimum flow area of the airflow passage 201 is too small, the funnel effect generated by the airflow in the airflow passage 201 is weak, the efficiency of converting the static pressure into the dynamic pressure of the airflow is reduced, the airflow flow speed is increased slowly, the air outlet speed of the jet nozzle 300 is reduced, and the jet effect is reduced; when the maximum flow area of the airflow passage 201 is greater than 4 times of the minimum flow area, the difference between the maximum flow area and the minimum flow area of the airflow passage 201 is too large, so that the airflow flows to the minimum flow area too fast, airflow is gathered too fast, congestion is generated in the airflow passage 201, and wind resistance is too large, so that normal air outlet is influenced; therefore, the maximum flow area of the airflow passage 201 is set to be 2-4 times of the minimum flow area, so that the funnel effect is generated in the flowing process of the airflow in the airflow passage 201, the flowing speed of the airflow is improved, the wind resistance is reduced, and the air outlet is more stable.

Optionally, the maximum flow area of the airflow passage 201 is 3 times its minimum flow area. Thus, the funnel effect is generated in the flowing process of the airflow in the airflow passage 201 while the airflow in the airflow passage 201 stably flows, the flowing speed of the airflow is improved, and the jet effect is improved.

Optionally, the jet orifice 300 is an arc-shaped structure. Like this, can make the air current that jet orifice 300 jetted out become the arc surface form, increase jet orifice 300's air-out region, make jet orifice 300's air-out can be better drive the change of the whole air-out angle of air conditioner, make the air conditioner air-out take place the skew to promote the efflux effect.

Optionally, the radian of the arc-shaped structure of the jet orifice 300 is greater than or equal to pi/3 and less than or equal to 2 pi/3. Like this, when the radian of jet orifice 300 is less than pi/3, can make the jet orifice undersize, lead to the air current to locate the gathering at jet orifice 300, cause the air current to block up, can't jet out fast, thereby reduce jet velocity and efflux effect, when the radian of jet orifice 300 is greater than 2 pi/3, the air current flows too steadily, can't jet out at a high speed, the air current that leads to jet orifice 300 to jet out can't influence the whole air-out of air conditioner, the air-out effect has been reduced, set up the radian between pi/3 to 2 pi/3, the change of the whole air-out angle of drive air conditioner that makes the air-out ability of jet orifice 300 better, make the air-conditioner air-out take place the skew, thereby promote the efflux effect.
