[0015] figure 1 It is a schematic diagram of the principle of the method of the present invention. see figure 1 The method for improving the suction capacity and distance of the suction port in the present invention is to set a number of jet nozzles 2 around the suction port driven by the power source to rotate around the suction port and to eject jets. The axis of the jet nozzle is inclined to the axis of the suction port. Jet flow is air flow (or steam or gas-liquid mixture).
[0016] figure 2 , image 3 It is a schematic diagram of the device structure of the present invention. see Figure 2 ~ Figure 3 The device of the present invention comprises an exhaust pipe 1A, an exhaust fan 1B installed at the outlet of the exhaust pipe, which is successively installed on the outer periphery of the exhaust pipe and is installed on the exhaust pipe through an outsourced rotary bearing 9, a gear reduction transmission mechanism 12 and a worm gear reducer 11. The rotating bellow...
