The embodiment provides an automatic sampling system, including advancing kind subassembly, sampling needle subassembly, carrying liquid subassembly and washing liquid subassembly, wherein advance the position distribution and the relation of connection of kind subassembly, sampling needle subassembly, carrying liquid subassembly and washing liquid subassembly and be conventional technical means, this application is no longer repeated.
As shown in fig. 1, the cleaning solution assembly of the present embodiment includes a fountain type cleaning apparatus including an overflow tank 1 and a cleaning cup 2 disposed in the overflow tank 1. The cleaning cup 2 is open, and the top of the cleaning cup is provided with an opening 21; the bottom of the cleaning cup 2 is provided with a liquid inlet interface which is communicated to a cleaning liquid supply container 4 through a liquid inlet pipe 3. The liquid inlet pipe 3 is provided with a sample injection pump 5 for continuously pumping the cleaning liquid to the cleaning cup 2.
Adopt the spring formula belt cleaning device of this embodiment, utilize the feed liquor pump to continue to pump the washing liquid in washing liquid supply container 4 to washing cup 2, the washing liquid upwards flows and overflows from the opening 21 of washing cup 2 from the bottom of washing cup 2, forms the effect of spring promptly for the washing liquid in the washing cup 2 has the mobility.
After the sampling needle 10 stretches into the cleaning cup 2, the sampling needle 10 absorbs the cleaning liquid in the cleaning cup 2 to wash the inner wall of the sampling needle 10, and the flowing cleaning liquid can directly wash the outer wall of the sampling needle 10. Compared with the traditional cleaning mode, the present embodiment can directly utilize the cleaning liquid with high cleanliness to clean the inner wall and the outer wall of the sampling needle 10 respectively. And because the washing liquid continues to flow into from the bottom of wasing cup 2 and washs cup 2, the washing liquid that is located the below can promote the washing liquid of its top and upwards flow for wash cup 2 can in time be discharged to the washing liquid after having washd sampling needle 10, with the cleanliness of the washing liquid of guaranteeing to wash in the cup 2, help improving the cleaning performance of sampling needle 10.
In the present embodiment, the cleaning solution overflowing from the opening 21 can flow into the overflow chute 1, and the bottom of the overflow chute 1 is provided with a waste discharge interface, and the waste discharge interface and the cleaning cup 2 are distributed at intervals, that is, the waste discharge interface is located outside the cleaning cup 2. The waste discharge port is communicated to a waste liquid tank through a waste discharge pipe 6.
