Although the sealing effect can be ensured by the plurality of sealing rings 301, the sealing rings 301 are pulled by the water cooling tubes 2 and the air tubes 1 which move relatively due to the relative movement between the water cooling tubes 2 and the air tubes 1, so that the sealing rings 301 are intertwined, and the sealing structure 3 fails.

Seal structure 3 in this embodiment is through addding flat pad 302 between sealing washer 301, and flat pad 302 can separate sealing washer 301, and when water-cooling pipe 2 and trachea 1 dragged sealing washer 301, sealing washer 301 can not take place to entangle to guarantee sealed effect, avoid seal structure 3 to become invalid.
