Further, the inlet end of the housing 1 is arranged with a partition 10.
The working principle of the invention is as follows: referring to fig. 4, in the vortex ring generating device based on the wind resistance rebound mechanism provided by the invention, initially, the fan blade air supply motor 3 is started, at this time, 4 fan blades 7 rotate around the fan blade air supply transmission shaft 4, and then, the dynamic wind resistance rebound driving motor 12 is started, the motor drives the main gear 5 to rotate, the main gear 5 rotates to drive 4 bevel gears 9 to rotate, and the fan blades 7 rotate around the wind resistance rebound transmission shaft 8. I.e. the fan blades 7 rotate themselves about the axis 8 while rotating about the main shaft 4. When the fan blades rotate around the shaft 8, when the fan blades 7 are inclined to the horizontal plane by a certain angle, the fan blades are stressed by wind in the longitudinal direction, and at the same time, due to the presence of the tooth-like structure 13, there will be a component of the longitudinal force in the direction of the axis 8, when this force component exceeds the tension of the spring guide (with the guide in the spring) 14, the tooth-like structures 13 will be forced apart from each other, and subsequently, because the fan blade 7 still has a certain inclination angle with the horizontal plane, the fan blade 7 is acted by the longitudinal force of air, because the spring guide rod 14 is coaxial with the shaft 8, so that the fan blade 7 rotates around the axis of the spring guide 14, and the inclination angle of the fan blade and the horizontal plane gradually decreases, when the horizontal inclination angle decreases to 0, because the tooth-shaped structure is already separated, the toothed structures are pulled back into engagement with one another only by the tension of the spring-guided rod 14 in the direction of the shaft 8 and subsequently continue to rotate by the bevel gear 9. Therefore, the cyclic process that the inclination angle of the fan blade and the water surface is gradually increased firstly and then is rapidly reduced to zero in the process that the fan blade 7 blows the air around the fan blade air transmission shaft 4, the inclination angle is maintained for a certain time, and then the inclination angle is gradually increased again is formed. When the fan blade 7 and the horizontal plane have a certain inclination angle, longitudinal wind can be generated, when the inclination angle is zero, the fan blade 7 does not generate wind in the longitudinal direction in the rotating process around the shaft 4, namely, the process can generate a section of intermittent air flow, then the intermittent air flow is curled through the reducing nozzle 11 to generate a vortex ring, the generation period is one, a vortex ring is generated when the inclination angle of the fan blade and the horizontal plane is zero, the device can continuously generate vortex ring ejection in the circulating process, and a large number of vortex rings can be rapidly generated.
The above is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereby, and therefore, the present invention is not limited by the scope of the claims.
