  • the main pipe in the second pipe 30 can move forward and backward relative to the first pipe 31, when the main pipe 30 moves forward, i.e, the main pipe 30 moves far away from the first pipe 31, the flared portion 221 also moves far away from the first pipe 31, the gap between the flared portion 221 and the plug core 313 is increased and thereby the amount of water entering the main pipe from the main water outlet pipe 8 is increased, i.e., the amount of water outlet from the jet nozzle 11 is increased; when the main pipe 30 moves backward, i.e, the main pipe 30 moves close to the first pipe31 , the flared portion 221 moves close to the first pipe 31, the gap between the flared portion 221 and the plug core 313 is decreased and thereby the amount of the water entering the main pipe 30 from the main water outlet pipe 8 is decreased, i.e, the amount of water outlet from the jet nozzle 11 is decreased.
  • the forward and backward movement of the main pipe 30 in the second pipe relative to the first pipe is realized by rotating the main pipe 30.
  • the above-described main pipe 30 is formed by two pipe sections by ultrasonic welding, one end of one pipe section (i.e., the first segment 22 in Fig. 11 ) has the flared portion 221, the outer surface of the other end of one pipe section (i.e., the first segment 22 in Fig. 11 ) has a threaded section which is screwed to the auxiliary pipe 26, and the outer surface of the other pipe section (i.e., the first segment 27 in Fig. 11 ) has a rotating part 301 protruding radially. Rotating the rotating part 301 to rotate the main pipe 30 and thereby the main pipe 30 move forward and backward relative to the auxiliary pipe 26 and the first pipe31.
  • the inner pipe wall 311, the flaring part 221, the outer pipe wall 312, and the arc pipe wall 261 on the auxiliary pipe 26 enclose to form an air inlet space which communicates with the interior of the main pipe and communicates with the inlet pipe 12 in the control pipeline 6.
  • An adjustment switch for adjusting air inlet volume is included on the inlet pipe 12. This embodiment may increase the pressure of the water and adjust the jet effect of the jet connector 11 by adjusting the air inlet volume.
  • a seal ring 28 and a seal pad 29 are included at the connection of the first pipe 31 and the outlet pipe 8.
  • a sealing ring 25 is included at the inner side surface of the inner pipe wall of the first pipe. The arrangements of the seal ring 28, the seal pad 29 and the sealing ring 25 are all used for sealing the connections between various pathways for better sealing.
  • This embodiment is an application example of embodiments 1 to 8.
  • the swimming training apparatus in the above embodiments may all be included in an overground pool or an underground pool.
  • Fig. 15 shows the swimming training apparatus according to embodiment 1 being applied to an underground pool 200.
  • Fig. 16 shows the swimming training apparatus according to embodiment 1 being applied to an overground pool 3.
  • Fig. 17 shows the swimming training apparatus according to embodiment 2 being applied to an overground water pool 3, and the support plate 33 being supported on the inner wall of the overground pool.
  • the separation of the drive mechanism and the pumping execution mechanism ensures the separation of water and power of the swimming training apparatus and thus ensures the safety in use of the swimming training apparatus. Therefore, the invention effectively overcomes the defects in the prior art and has high industry values.
