[0023] Example 1
[0024] See figure 1 , figure 2 with image 3 As shown, the device is installed in a centrifugal fan volute 1 to form a centrifugal fan: including a drive motor 2, a volute 1, and an air inlet 6 arranged on the left side of the volute 1, and a tangent direction along the circular casing of the volute 1. The air outlet channel 7 is provided with a rotary air centrifugal force generating device in the volute 1, and the driving motor 2 drives the rotary air centrifugal force generating device to rotate, so that the air in the volute 1 generates centrifugal force, and the air on the side of the air inlet 6 The suction and outlet air channel 7, the rotary air centrifugal force generating device includes the spiral channel left side wall 3, the spiral channel right side wall 4, and a set of spiral channel partition walls 5. The spiral channel left side wall 3 is an annular plate, an annular plate The inner circular hole corresponds to the air inlet 6 of the volute 1,...
