the third gear 502 is engaged with the second gear 506, the second gear 506 is fixedly connected with one end of the second connecting rod 507, the other end of the second connecting rod 507 is fixedly connected with one end of the third connecting rod 508, and the other end of the third connecting rod 508 can be configured above the outlet of the water outlet pipe 407;

the structural body composed of the two sets of the first link 503, the first slider 504, and the first guide rail 505 is disposed symmetrically with respect to the axis of the third gear 502.

According to the invention, the second rotating shaft 307 rotates around the axis of the first rotating shaft 206, so that the fifth rotating shaft 501 revolves around the axis of the first rotating shaft 206, and the second gear ring 506 rotates around the axis of the first rotating shaft 206, so that the first connecting rod 503 drives the first sliding block 504 to move left and right, the water outlet pipe 407 swings, the relative volume of water sprayed out is increased, the contact area with air is increased, the oxygen content of water is increased, and the second gear ring 506 drives the third connecting rod 508 to hit the water sprayed out of the water outlet pipe 407 in the rotating process, so that the water is beaten into fine water drops, and the oxygen content is further increased.

The second connecting rod 507 and the third connecting rod 508 are symmetrically disposed about the axis of the first rotating shaft 206.

Wherein, a person skilled in the art can adjust the position of the motor 201 as required, in order to prevent the second connecting rod 507 from interfering with the motor 201 and the first belt 204 and the second belt 402, the diameter of the second gear ring 506 is larger than the distance from the motor 201 to the first rotating shaft 206, the motor 201 is embedded in the second gear ring 506 and is not in contact with the teeth of the second gear ring 506, and the service life of the motor 201 is protected.

As a further explanation of this example, referring to fig. 8, the first rotating shaft 206 and the second rotating shaft 207 are arranged perpendicularly to each other in the longitudinal direction.

The present invention ensures that the second rotation shaft 207 rotates around the first rotation shaft 206.

As a further explanation of this example, with reference to fig. 7, the outlet pipe 407 is shaped like an L.

The present invention ensures that the outlet pipe 407 sprays water out of the water surface and back into the pool.

As a further explanation of this example, with reference to fig. 7, the end of the inlet pipe 406 is provided with a sieve.

The intake pipe 406 of the present invention prevents the intake of fish.

For further explanation of this example, referring to fig. 6 to 7, the first slider 504 is dovetail-shaped, and the first guide rail 505 has a dovetail groove.

According to the invention, the first slider 504 is matched with the dovetail groove of the first guide rail 505, so that the first slider 504 does not move left and right and does not move longitudinally.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
