Embodiment 1
[0028] Such as Figure 1 to Figure 4 As shown, the water tank assembly for on-line cleaning and sterilization of needle irrigation in this embodiment includes a cleaning water tank 1, a cleaning medium input pipeline 2 and a cleaning medium discharge pipeline 3, and a discharge switching valve is arranged on the cleaning medium discharge pipeline 3 15. The cleaning water tank 1 is provided with a cleaning medium channel 4 and a needle irrigation chamber 5 into which the irrigation needle 8 can be inserted. The inlet end of the cleaning medium channel 4 is connected with the cleaning medium input pipeline 2 , and the outlet end of the needle irrigation cleaning chamber 5 is connected with the cleaning medium discharge pipeline 3 . The cleaning medium channel 4 is provided with a plurality of nozzles 7 leading to the needle irrigation cleaning chamber 5 along the length of the channel. The nozzles 7 face the irrigation needles 8 in the needle irrigation cleaning chamber 5 and ca...
Embodiment 2
[0034] Such as Figure 5 As shown, the water tank assembly for on-line cleaning and sterilization of needle irrigation in this embodiment includes a cleaning water tank 1, a cleaning medium input pipeline 2 and a cleaning medium discharge pipeline 3, and a discharge switching valve is arranged on the cleaning medium discharge pipeline 3 15. The cleaning water tank 1 is provided with a cleaning medium channel 4 and a needle irrigation chamber 5 into which the irrigation needle 8 can be inserted. The inlet end of the cleaning medium channel 4 is connected with the cleaning medium input pipeline 2 , and the outlet end of the needle irrigation cleaning chamber 5 is connected with the cleaning medium discharge pipeline 3 . The cleaning medium channel 4 is provided with a plurality of water passage holes 6 leading to the needle irrigation cleaning chamber 5 along the length of the passage. The water passage holes 6 face the irrigation needles 8 in the needle irrigation cleaning cham...
Embodiment 3
[0039] Such as Figure 6 As mentioned above, the water tank assembly for on-line cleaning and sterilization of irrigation needles in this embodiment is basically the same in structure as that of Embodiment 2, the difference is that the cover plate 18 is fixedly connected with the irrigation needle 8 and cleaned at the irrigation needle 8 The hour cover is arranged on the box body 17 , and the box body 17 is provided with a second sealing member 21 for sealing with the cover plate 18 . The water tank of this form has a simpler sealing structure.
[0040] In this embodiment, the box body 17 is provided with a locking mechanism 22 for locking the cover plate 18 on the box body 17 when the cover plate 18 is set on the box body 17. The locking mechanism 22 is a conventional The conventional locking structure will not be repeated here.
[0041] When filling the filling needle 8, since the cover plate 18 and the filling needle 8 are fixedly connected as one, the cover plate 18 and ...
