The container body 1 of the present embodiment is preferably a cube or a rectangular parallelepiped, and both side walls of the partition plate 2 are connected to both adjacent side walls of the container body 1, respectively, and the shape of the container body 1 is not limited to the rectangular parallelepiped shape shown in the drawing, and may be a regular shape such as a cylindrical shape or a polygonal column shape.

In this embodiment, a cleaning cup 5 is disposed in the cleaning liquid tank 3, and a cleaning liquid waste outlet 31 is disposed at the bottom of the cleaning liquid tank 3 and outside the cleaning cup 5, that is, the cleaning liquid waste outlet 31 and the cleaning cup 5 are disposed at an interval. The top of the cleaning cup 5 is provided with an opening, and the bottom of the cleaning cup 5 is provided with a cleaning liquid inlet and a cleaning liquid outlet. And pipe joints are respectively arranged at the cleaning liquid inlet and the cleaning liquid outlet to connect pipelines. The cleaning liquid is supplied into the cleaning cup 5 through the cleaning liquid inlet, and the cleaning liquid in the cleaning cup 5 can be discharged through the cleaning liquid outlet to replace the cleaning liquid in the cleaning cup 5. When the cleaning liquid in the cleaning cup 5 is large, the cleaning liquid overflows from the top of the cleaning cup 5 into the cleaning liquid tank 3, and the cleaning liquid overflowing from the cleaning cup 5 into the cleaning liquid tank 3 can be discharged through the cleaning liquid discharge port 31.

In this embodiment, the bottom of the liquid carrying tank 4 is provided with a liquid carrying supply outlet 41, the liquid carrying supply outlet 41 is provided with a liquid carrying joint 42, the liquid carrying joint 42 is provided with a liquid carrying inlet and a liquid carrying outlet, and the liquid carrying supply tank 4 can be supplied with the liquid carrying through the liquid carrying supply joint 42 or the liquid carrying in the liquid carrying tank 4 can be discharged.

In the embodiment, the cleaning tank and the current-carrying tank are integrated in the container body 1, and the container body 1 is arranged on the main body bracket of the automatic sample introduction system, so that the requirements of cleaning the sampling needle and supplying carrier liquid can be met. Compared with the traditional split type cleaning assembly and the current-carrying assembly, the liquid-carrying groove and the cleaning groove of the integrated assembly of the embodiment have fewer assembling parts, simple structure and convenient installation.

As shown in fig. 3, the cleaning cup 5 and the cleaning liquid tank 3 in this embodiment are of an assembly structure, and a through hole is formed at the bottom of the cleaning liquid tank 3, and the through hole includes a large hole located above, a small hole located below, and a step end face located between the large hole and the small hole. The cleaning cup 5 comprises a cup body 51, a primary shaft shoulder 52 formed on the side wall of the cup body 51 and a secondary shaft shoulder 53 formed on the side wall of the primary shaft shoulder 52 in sequence from top to bottom.

A cleaning cup 5 extends into the cleaning tank from the lower part of the cleaning tank 3, a primary shaft shoulder 52 on the cleaning cup 5 is abutted against the end face of the step, and a secondary shaft shoulder 53 on the cleaning cup 5 is abutted against the bottom wall of the cleaning tank 3. In this embodiment, the side wall 12 of the container body 1 extends downward to form a receiving space below the bottom wall 11 for receiving the secondary shoulder 53 and the liquid carrying joint 42. In order to ensure the sealing between the cleaning cup 5 and the cleaning liquid tank 3, a sealing ring is arranged between the primary shaft shoulder 52 and the step end face. In some embodiments, the cleaning cup 5 and the cleaning tank may be integrally formed.

In the present embodiment, an overflow structure 6 is further disposed in the cleaning liquid tank 3, and the overflow structure 6 is located outside the cleaning cup 5, i.e. the overflow structure 6 is spaced from the cleaning cup 5. The overflow structure 6 comprises a boss 61 protruding out of the bottom of the cleaning liquid tank 3, an overflow hole 62 is formed in the boss 61, and the overflow hole 62 penetrates through the bottom of the cleaning liquid tank 3 from the boss 61. In this embodiment, for easy opening, an overflow hole 62 vertically penetrates the bottom of the cleaning liquid tank 3 from the top of the boss 61. In some embodiments, the overflow holes 62 may extend from the side wall of the boss 61 through the bottom of the cleaning liquid tank 3. If the cleaning liquid in the cleaning liquid tank 3 can not be discharged quickly through the cleaning liquid waste discharge port 31, after the liquid level in the cleaning liquid tank 3 exceeds the overflow hole 62, the cleaning liquid can be discharged through the overflow hole 62, and the cleaning liquid is prevented from overflowing the container body 1. In the cleaning liquid tank 3, the opening of the overflow hole 62 may be higher than the bottom of the cleaning liquid tank 3, and the height difference between the opening of the overflow hole 62 and the bottom of the cleaning liquid tank 3 may be designed according to actual requirements.

The upper parts of the cleaning liquid tank 3 and the carrier liquid tank 4 of the present embodiment have a communicating structure, as shown in fig. 3 and 4, the top of the partition board 2 of the present embodiment is lower than the top of the side wall 12, and the communicating structure is a part where the partition board 2 and the side wall 12 form a height difference. Because the cleaning liquid tank 3 and the liquid carrying tank 4 are formed by the partition board 2 in a separating way, and part of the side walls of the cleaning liquid tank 3 and the liquid carrying tank 4 are both formed by the partition board 2, when the height difference exists between the top of the partition board 2 and the top of the side wall 12, the cleaning liquid tank 3 and the liquid carrying tank 4 are communicated with the part of the height difference formed between the partition board 2 and the side wall 12.

The partition plate 2 and the overflow structure 6 in the cleaning liquid tank 3 are used in cooperation, when the cleaning liquid in the cleaning liquid tank 3 is too much, the cleaning liquid in the cleaning liquid tank 3 cannot flow into the liquid carrying tank 4 beyond the partition plate 2, and the liquid carrying in the liquid carrying tank 4 is ensured not to be polluted by the cleaning liquid. When the carrier liquid in the carrier liquid tank 4 is excessive, the carrier liquid can flow into the cleaning liquid tank 3 through the partition plate 2. The carrier liquid in the cleaning liquid tank 3 can be discharged from the cleaning liquid waste discharge port 31 and the overflow hole 62, and the carrier liquid is prevented from overflowing from the side wall 12 of the container body 1.

It should be noted that the communication structure of the present application is not limited to the structure described in the present embodiment, and in some embodiments, the partition plate 2 is disposed at the same height as the side wall 12 of the container body 1, and the cleaning liquid tank 3 and the liquid carrying tank 4 are communicated by forming a through hole in the partition plate 2.

As shown in FIG. 3, the top of the cleaning cup 5 of the present embodiment is higher than the top of the partition plate 2. Because there is the difference in height at the top of wasing cup 5 and the top of baffle 2, when the carrier liquid in carrier liquid groove 4 floods baffle 2, the carrier liquid can't take place to mix through the top of wasing cup 5 and the washing liquid in wasing cup 5, avoids the washing liquid to be polluted by the carrier liquid.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
