[0035] The above technical solution can be used to conveniently and stably fix the storage tank 3 on the bracket 1. When in use, the insert tube 4 at the bottom of the storage tank 3 is aligned with the slot 2 of the bracket 1 and inserted into the liquid inlet cavity 28 of the socket 7. In order to ensure that the storage tank 3 does not shake, the mechanical claw mechanism 6 is used to fix the outer edge plate 5 on the side of the storage tank 3.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, the quick-connect assembly includes:

[0037] A socket 7 is provided with a liquid inlet cavity 28 and a discharge cavity 22, and the socket 7 is provided at the upper end of the bottom plate 26. A liquid infusion tube 8 is connected between the discharge cavity 22 and the liquid inlet. A partition for separating the liquid inlet cavity 28 and the discharge cavity 22 is provided in the socket 7, and a penetration groove 24 is provided on the partition. A liquid flow controller is connected to the liquid infusion tube 8 to control the flow of the test solution in the liquid infusion tube 8 to achieve quantitative delivery;

[0038] A cannula 4 is provided with a guide groove 25, one end of the cannula 4 is connected to the liquid outlet, and the guide groove 25 and the penetration groove 24 form an infusion channel;

[0039] A first sealing assembly for blocking the guide groove 25; specifically, the first sealing assembly includes: a guide column 18 slidably disposed in the guide groove 25, a first piston plate 17 being disposed at one end of the guide column 18, the first piston plate 17 being used to block the guide groove 25; a first elastic member 19 for pushing the first piston plate 17 to block the guide groove 25; and a top column 20 disposed at the upper end of the partition plate for resisting the guide column 18;

[0040] A second sealing component for blocking the penetration groove 24. When the other end of the cannula 4 is inserted into the liquid inlet cavity 28, the first sealing component and the second sealing component successively open the guide groove 25 and the penetration groove 24, so that the infusion channel is connected; specifically, the second sealing component includes: a second piston plate 21 arranged in the discharge cavity 22, the second piston plate 21 is used to block the penetration groove 24; a guide rod 23 arranged on the surface of the second piston plate 21, the guide rod 23 is slidably connected to the socket 7; a second elastic member for pushing the second piston plate 21 to block the penetration groove 24, one end of the second elastic member is arranged in the discharge cavity 22, and the other end of the second elastic member abuts against the second piston plate 21;

[0041] The above technical solution can avoid mixing air when installing or replacing the storage tank 3. When the cannula 4 is inserted into the socket 7, the top column 20 and the guide column 18 are gradually fitted together. At the same time, the bottom of the cannula 4 will contact the guide rod 23, thereby applying downward pressure to the second piston plate 21. As the cannula 4 continues to penetrate into the liquid chamber 28, the second piston plate 21 moves downward first, so that the second piston plate 21 opens the penetration groove 24. At this time, the top column 20 and the guide column 18 fit together, thereby applying upward pressure to the first piston plate 17, so that the first piston plate 17 is pushed upward. The guide groove 25 and the air inlet groove 16 are opened. At this time, the test solution in the storage tank 3 enters the liquid inlet cavity 28 through the guide groove 25, and then is sent to the discharge cavity 22 through the penetration groove 24, and the test solution is sent to the reactor 9 through the infusion tube 8. Therefore, in order to open the infusion channel, the first sealing component and the second sealing component must work normally at the same time to ensure that the test solution enters the reactor 9, that is, both the guide groove 25 and the penetration groove 24 need to be opened, with a double protection structure to prevent air from entering the reactor 9 when the storage tank 3 is docked and installed with the socket 7.

[0042] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, the first sealing assembly also includes: an air intake pipe 15 with an opening at one end, the opening of the air intake pipe 15 is connected to the guide groove 25, an air intake groove 16 is opened on the surface of the air intake pipe 15, one end of the first elastic member 19 is connected to the inner wall of the air intake pipe 15, the other end of the first elastic member 19 is in contact with the first piston plate 17, and the first piston plate 17 blocks the air intake groove 16 before being lifted by the guide column 18;

[0043] The above technical solution can have a triple protection structure. During the process of inserting the cannula 4 into the socket 7, the top column 20 fits with the guide column 18, thereby applying upward pressure to the first piston plate 17, so that the first piston plate 17 moves up to open the guide groove 25 and the air inlet groove 16. At this time, the test solution in the storage tank 3 flows into the guide groove 25 through the air inlet groove 16 on the surface of the air inlet pipe 15, and the test solution enters the liquid inlet cavity 28, and then the test solution is sent to the discharge cavity 22 through the penetration groove 24, and the test solution is sent to the reactor 9 through the infusion tube 8. Therefore, in order to open the infusion channel, the first sealing component and the second sealing component must work normally at the same time to ensure that the test solution enters the reactor 9, that is, the air inlet groove 16, the guide groove 25 and the penetration groove 24 are all opened, with a double protection structure to better prevent air from entering the reactor 9 when the storage tank 3 is docked and installed with the socket 7.

[0044] Further, such as Figure 3 As shown, the conveying device also includes: a sealing ring 13 with a slide rod 10 at one end, the slide rod 10 is slidably matched with a slide groove 11 opened inside the socket 7, and the sealing ring 13 is consistent with the cannula 4; a third elastic member 12 is arranged in the slide groove 11, and the third elastic member 12 is used to push the slide rod 10 to move toward the storage tank 3 so that the sealing ring 13 and the cannula 4 are fully fitted; a sealing cover 14 is arranged between the sealing ring 13 and the socket 7;

[0045] The adoption of the above technical solution can further improve the sealing performance of the connection between the socket 7 and the cannula 4. In order to further improve the sealing performance between the socket 7 and the cannula 4, a sealing ring 13 is provided. When the cannula 4 is inserted into the liquid inlet cavity 28 of the socket 7, the third elastic member 12 will exert an upward elastic force on the slide rod 10, so that the sealing ring 13 fits with the cannula 4. In order to ensure that the sealing ring 13 fits stably with the cannula 4, the side of the cannula 4 should be provided with a certain inclination angle.

[0046] Working principle: When in use, first align the cannula 4 at the bottom of the storage tank 3 with the slot 2 of the bracket 1, so that the cannula 4 is inserted into the liquid inlet cavity 28 of the socket 7. In order to ensure that the storage tank 3 does not shake, the outer edge plate 5 on the side of the storage tank 3 is fixed by the mechanical claw mechanism 6. In the process of inserting the cannula 4 into the socket 7, the top column 20 and the guide column 18 gradually fit together, and at the same time, the bottom of the cannula 4 will resist the guide rod 23, thereby exerting downward pressure on the second piston plate 21. As the cannula 4 continues to penetrate into the liquid inlet cavity, the top column 20 and the guide column 18 gradually fit together. The second piston plate 21 first moves downward, so that the second piston plate 21 opens the penetration groove 24. At this time, the top column 20 fits with the guide column 18, thereby applying upward pressure to the first piston plate 17, so that the first piston plate 17 moves upward to open the guide groove 25 and the air inlet groove 16. At this time, the test solution in the storage tank 3 flows into the guide groove 25 through the air inlet groove 16 on the surface of the air inlet pipe 15, and then the test solution is sent to the discharge cavity 22 through the penetration groove 24, and the test solution is sent to the reactor 9 through the infusion tube 8;

[0047] In order to further improve the sealing between the socket 7 and the cannula 4, a sealing ring 13 is provided. When the cannula 4 is inserted into the liquid inlet cavity 28 of the socket 7, the third elastic member 12 will exert an upward elastic force on the slide rod 10, so that the sealing ring 13 fits with the cannula 4. In order to ensure that the sealing ring 13 fits stably with the cannula 4, the side of the cannula 4 should be provided with a certain inclination angle.
