[0025] Furthermore, the inner diameter of the container 3 is larger than the diameter of the connecting groove 15, so that the test tube opening can abut against the upper surface of the base 2, thereby allowing the test tube to be placed inside the container 3. The inner wall of the connecting groove 15 is chamfered 12, which facilitates water flow into the water collection cover 16 through the base 2.
[0026] Furthermore, the top of the washing tube 4 is positioned higher than the top of the container tube 3, making it easier to remove the test tube.
[0027] Furthermore, two placement slots 14 are provided at the bottom of the container 3. The transmitter and receiver of the photoelectric sensor are respectively fixed in the two placement slots 14, so as to identify whether the test tube has been placed.
[0028] Furthermore, a water pump 11 is provided on the drain pipe 7 and the water pump 11 is fixedly installed on the receiving plate 10.

[0029] It is understood that the rotary connector 8 is existing technology, and the connectors at both ends of the rotary connector 8 can rotate relative to each other.
[0030] In this embodiment of the invention, photoelectric sensors are respectively installed in two placement slots 14 to identify whether the test tube has been placed. Water is delivered to the washing tube 4 through the water inlet pipe 9, and then sprayed into the test tube through the spray nozzle 6.
