[0031] In order to clean the tuning fork terminal 22 more comprehensively, a water distribution ring 4 is arranged in the inner part of the flange pipe 11 and communicates with the cleaning jacket 3. The water distribution ring 4 can uniformly distribute the cleaning water. The water distribution ring 4 is sleeved on the tuning fork rod 21 and movably connected in the flange pipe 11. The inner ring of the water distribution ring 4 is the same as the outer diameter of the tuning fork rod 21. The outer ring of the water distribution ring 4 is the same as the inner diameter of the flange pipe 11. The water distribution ring 4 can slide on the tuning fork rod 21. The water distribution ring 4 is a hollow structure. The top of the water distribution ring 4 is provided with a water inlet hole 41. A self-sealing assembly is arranged on the water inlet hole 41. The self-sealing assembly comprises a sealing gasket 42 and a tension spring 5. The sealing gasket 42 is fixed on the top of the flange pipe 11 and used for sealing the water inlet hole 41. The tension spring 5 is fixedly arranged in the cleaning jacket 3 and used for pulling the water distribution ring 4. In the non-cleaning state, the water inlet hole 41 on the top of the water distribution ring 4 is tightly attached to the sealing gasket 42 under the action of the tension spring 5, so as to seal the water inlet hole 41. In the cleaning state, the water inlet hole 41 loses the sealing effect because the water inlet hole 41 is pressed downward by the water. The cleaning water enters the water distribution ring 4 through the water inlet hole 41. After cleaning, the water distribution ring 4 is lifted again under the action of the tension spring 5 to seal the water inlet hole 41, so as to realize the self-sealing of the water inlet hole 41.

The cleaning pipe 6 is provided with a cleaning hole 8 corresponding to one side of the tuning fork terminal 22. The cleaning holes 8 arranged around the tuning fork terminal 22 can better complete the cleaning effect. The cleaning hole 8 is inclined upward, so that the water flow in the cleaning hole 8 is inclined upward. The water flow inclined upward can form a downward thrust to assist the water flow to move the water distribution ring 4 downward. On the other hand, the water flow inclined upward in the cleaning hole 8 can better incline the viscous material in the tuning fork terminal 22, so as to avoid the viscous material remaining and make the cleaning more thorough.
