[0034] Example 2

[0035] See also Figures 1 to 5 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

The fixed frame 31 is screwed together with the support plate 21 and the fan 32 by screws. The fan 32 is started to suck the airflow, and the airflow is transported into the limiting ring 23. Then, the airflow in the limiting ring 23 is ejected from the air outlet 332, the air pressure in the limiting ring 23 is reduced, and the gas in the limiting ring 23 flows and enters the limiting ring 23, thereby increasing the airflow flow effect in the limiting ring 23.

[0036] In this embodiment, an annular flow cavity is provided inside the circulation ring 33, and the outlet end of the fan 32 is connected with the flow cavity of the circulation ring 33 through a pipeline.
