After the at least one partition 24 is disposed in the cavity 25, the cavity 25 may be divided into a main flow channel 26 and at least one backflow channel 27, two ends of the main flow channel 26 are respectively disposed opposite to the air inlet 21 and the air outlet 22, an inlet 240 of the backflow channel 27 is defined between one end of the partition 24 adjacent to the air outlet 22 and the housing 23, and an outlet 241 of the backflow channel 27 is defined between one end of the partition 24 adjacent to the air inlet 21 and the housing 23. That is, when the air flow enters the main flow channel 26 through the air inlet 21, the air flow will flow toward the air outlet 22, and when the air flow flows to the air outlet 22, a part of the air flow enters the return flow channel 27 from the inlet 240 of the return flow channel 27 due to the blocking of the housing 23, and then returns to the main flow channel 26 from the outlet 241 of the return flow channel 27.

Deflection airflow swirl effect: as shown in fig. 2, after the deflected airflow approaches the lower partition 24, due to the "coanda" effect, part of the airflow will move along the lower partition 24, and the main airflow moves near the surface of the lower partition 24, meanwhile, the airflow in the return channel 27 will flow in the reverse direction at the upper partition 24 along the direction of the air inlet 21, generating a scroll effect, which will further push the main airflow to one side of the lower partition 24, and at the same time, generate a downward deflection speed at the air outlet 22.
The main air flow is pushed to one side of the baffle 24 at the lower end, and the flow rate of the air flow at the inlet 240 of the return channel 27 at the side is larger than that of the air flow at the inlet 240 of the return channel 27 at the upper end, so that the main air flow deflection effect and the deflected air flow scroll effect occur at the opposite side, and thus, upward and downward periodic flows are generated at the air outlet 22, and the self-oscillation effect is generated.
Specifically, as shown in fig. 1 and 2, the at least one partition 24 further includes: the first air guiding section 243 extends in a direction away from the air outlet 22, the first air guiding section 243 is obliquely arranged in a direction towards the main flow passage 26, the second air guiding section 244 extends in a direction away from the air inlet 21, the second air guiding section 244 is obliquely arranged in a direction towards the main flow passage 26, an outlet 241 of the return flow passage 27 is defined between the first air guiding section 243 and the casing 23, an inlet 240 of the return flow passage 27 is defined between the second air guiding section 244 and the casing 23, and the first arc-shaped air guiding section 242 is connected between the first air guiding section 243 and the second air guiding section 244.
The first air guiding section 243 extends in a direction away from the air outlet 22, and the first air guiding section 243 is obliquely arranged in a direction towards the main flow passage 26, so that it can be ensured that the air flow is deflected along the first air guiding section 243 after entering the cavity 25, the second air guiding section 244 extends in a direction away from the air inlet 21, and the second air guiding section 244 is obliquely arranged in a direction towards the main flow passage 26, so that the air flow can be guided to the air outlet 22 along the second air guiding section 244 more conveniently, and then the air flow is guided out from the air outlet 22. The first air guiding section 243 and the casing 23 define therebetween an outlet 241 of the return channel 27, the second air guiding section 244 and the casing 23 define therebetween an inlet 240 of the return channel 27, and a part of the air flow can enter the return channel 27 from between the second air guiding section 244 and the casing 23 and then return to the main flow channel 26 from between the first air guiding section 243 and the casing 23. The first arc-shaped flow guiding section 242 is connected between the first flow guiding section 243 and the second flow guiding section 244, and the first arc-shaped flow guiding section 242 is not tangent to the first flow guiding section 243, that is, the airflow can expand outward along the first arc-shaped flow guiding section 242 after moving along the first flow guiding section 243, so that the airflow generates a scroll effect high pressure area along the first arc-shaped flow guiding section 242, and pushes the main airflow to the opposite side partition plate 24, so that the main airflow generates a bending direction.
