The mixing drive 800 and the mixing valve 801 are disposed at the base 701 of the support 70 and are connected to the transfer member 650 through an external pipeline (not shown in the figure).

[0045] The mixing component 80 enables automatic and uniform mixing of the sample and washing solution in the third liquid storage unit 62, avoiding the uneven mixing and concentration errors caused by traditional manual shaking; the control mechanism of the mixing valve 801 enables the mixing operation to be performed immediately after volume adjustment, without the need for manual equipment switching, reducing operation steps and time, improving the continuity of the experimental process and the consistency of results, thereby improving detection accuracy and experimental efficiency.

[0046] like Figure 2 and Figure 4 As shown, Figure 4 yes Figure 2 A schematic diagram of the clamping assembly structure in the rinsing and transfer mechanism of the embodiment is shown. The rinsing and transfer mechanism 1 further includes a clamping assembly 81, which includes a clamping member 810, a clamping moving member 811, and a clamping connecting member 812. The clamping moving member 811 is disposed on the bracket 70, and the clamping connecting member 812 connects the clamping member 810 and the clamping moving member 811. The clamping member 810 is used to clamp and transfer the second liquid storage container 60 and / or the third liquid storage container 62. In some embodiments, the clamping moving member 811 is fixed on the base 701 of the bracket 70 to change the position of the clamping member 810. The clamping connecting member 812 mechanically connects the clamping member 810 and the clamping moving member 811 to transmit motion. The clamping member 810 is used to clamp and transfer the third liquid storage container 62. The clamping member 810 may be, but is not limited to, a claw structure.

[0047] like Figure 2and Figure 4 As shown, the clamping and moving member 811 includes a first-direction clamping and moving member 8110, a second-direction clamping and moving member 8111, and a third-direction clamping and moving member 8112. The first-direction clamping and moving member 8110 is fixed between the base 701 and the test tube placement surface 700. The first-direction clamping and moving member 8110 drives the second-direction clamping and moving member 8111 along the first direction ( Figure 2 The second direction clamping moving part 8111 moves along the second direction (X direction), and the third direction clamping moving part 8112 drives the third direction clamping moving part 8112 along the second direction (X direction). Figure 2 The third-party clamping moving part 8112 moves along the third-party direction (Y direction), and the clamping connecting part 812 drives the clamping connecting part 812 along the third-party direction (Y direction). Figure 2 The clamping connector 812 moves along the first direction (Z direction), thereby causing the clamping connector 810 to move along the first direction (Z direction). Figure 2 (Central X direction), Second direction ( Figure 2 (Y-direction) and third-party direction ( Figure 2 In some embodiments, because the clamping moving member 811 needs to precisely grip a single second reservoir 60 or third reservoir 62, the clamping moving member 811 needs to be able to drive the clamping member 810 in the first direction (Z direction). Figure 2 (Central X direction), Second direction ( Figure 2 (Y-direction) and third-party direction ( Figure 2 In the Z-direction, the first direction clamping moving part 8110, the second direction clamping moving part 8111, and the third direction clamping moving part 8112 are nested linear slide module structures.

[0048] like Figure 2 and Figure 5 As shown, Figure 5 yes Figure 2The embodiment shows a schematic diagram of the clamping component structure in the rinsing and transferring mechanism. The rinsing and transferring mechanism 1 also includes a first cleaning component 82 and a second cleaning component 83. The first cleaning component 82 and the second cleaning component 83 are disposed on the test tube placement surface 700. The first cleaning component 82 is provided with a first cleaning tank 820, and the second cleaning component 83 is provided with a second cleaning tank 830. The first cleaning tank 820 is used to clean the rinsing and transferring component 640, and the second cleaning tank 830 is used to clean the transferring component 650. In some embodiments, a first cleaning component 82 is disposed on the test tube placement surface 700 and equipped with a first cleaning tank 820, which is specifically used for containing and cleaning the rinsing component 640; a second cleaning component 83 is also disposed on the test tube placement surface 700 and equipped with a second cleaning tank 830, which is specifically used for containing and cleaning the transfer component 650; the first cleaning tank 820 is designed as a shallow, slender cylindrical structure with an upward opening, and its number is the same as the number of rinsing components 640, with an overflow hole at the bottom to guide the waste liquid to be automatically discharged; the second cleaning tank 830 adopts a similar shallow, slender cylindrical design and is specifically used for cleaning the transfer component 650, with a drain channel and drain port at the bottom to allow waste liquid to be discharged. This independent arrangement ensures that the rinsing component 640 and the transfer component 650 are physically isolated during the cleaning process, and the cleaning liquids will not mix with each other, avoiding cross-contamination.

[0049] like Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the integrated spray and suction mechanism according to an embodiment of this application. Figure 7 yes Figure 6The schematic cross-sectional view of the embodiment at point BB shows that the integrated spray-suction mechanism includes: a second liquid storage unit 60, a housing assembly 10, a suction assembly 50, and a supply assembly 51. The second liquid storage unit 60 is a container for storing a transfer liquid, which can be a sample or a mixture of a sample and a washing solution. The second liquid storage unit 60 may be filled with liquid or left empty. In some embodiments, the housing assembly 10 has a receiving space 12 for transferring and storing the washing solution. In some embodiments, the suction assembly 50 includes a first conduit 500 that passes through the housing assembly. The housing assembly 10 is disposed within the second liquid storage unit 60. The suction assembly 50 draws liquid from the second liquid storage unit 60 through the first pipe 500. The supply assembly 51 includes a third pipe 510 and a second pipe 11. A gap 5100 is provided between the second pipe 11 and the first pipe 500. The second pipe 11 and the third pipe 510 are located at both ends of the housing assembly 10 and are connected but do not enter the accommodating space 12. The second pipe 11 is provided with one or more liquid outlets 30, and the first pipe 500 is provided with a liquid inlet 5000. The supply assembly 51 releases liquid into the second liquid storage unit 60 through the gap 5100 and the liquid outlets 30. By directly passing the first pipe 500 through the housing assembly 10 into the second liquid storage unit 60, the liquid in the second liquid storage unit 60 is drawn in. The third pipe 510 is connected to the accommodating space 12 in the housing assembly 10, so that the liquid in the third pipe 510 is transported through the gap 5100 between the first pipe 500 and the second pipe 11. This arrangement can make the most of the space in the housing assembly 10 without having to add another pipe for transporting the cleaning solution. In order to ensure that the second pipe 11 can fully spray the cleaning solution onto the side wall of the second liquid storage unit 60, a certain height difference is set between the liquid inlet 5000 and the liquid outlet 30.

[0050] like Figure 6 , Figure 7 and Figure 12 As shown, Figure 12 yes Figure 7 A partial cross-sectional view of the embodiment shows a first channel 110 within the first conduit 500. In some embodiments, to ensure that the first conduit 500 can fully draw in the sample or a mixture of sample and washing solution from the second liquid reservoir 60, the first channel 110 extends into the second liquid reservoir 60 near its bottom, forming a gap 5100 between the outer wall of the first conduit 500 and the inner wall of the second conduit 11. In some embodiments, the second conduit 11 is a sleeve outside the first conduit 500, with a portion of the first conduit 500 disposed within the second conduit 11. By providing the second conduit 11, two flow channels are separated inside and outside the first conduit 500. Wherein, F1 is a schematic diagram of the liquid flow direction within the second conduit 11, and F2 is a schematic diagram of the liquid flow direction within the first conduit 500.

[0051] Because the wetting solution and sample need to be precisely controlled in this experiment, the size of the second liquid storage component 60 is usually small. In some embodiments, the diameter of the housing assembly 10 ranges from 30mm to 50mm, and the diameter range of the housing assembly 10 can be, but is not limited to, 33mm, 37mm, 41mm, 45mm, etc. At the same time, because the size of the integrated spray and suction mechanism is small, the drive device for controlling the integrated spray and suction mechanism is not located inside the housing assembly 10, thereby achieving cost control and size simplification.

[0052] like Figure 7 and Figure 8 As shown, Figure 8 yes Figure 6 The exploded structural diagram of the embodiment shows that the shell assembly 10 further includes a connecting assembly 20, which includes a first connecting portion 200, a second connecting portion 201, and a third connecting portion 202. The connecting assembly 20 is used to connect and protect the first pipeline 500, the second pipeline 11, and the third pipeline 510. The second connecting portion 201 is disposed between the first connecting portion 200 and the second pipeline 11, and the first connecting portion 200 is disposed on the side of the second connecting portion 201 facing away from the second liquid storage device 60. In some embodiments, the first connecting portion 200 and the second connecting portion 201 enclose a receiving space 12. The second pipeline 11 and the first pipeline 500 communicate with the receiving space 12. Liquid enters the gap 5100 through the receiving space 12, thereby entering the second liquid storage device 60. The receiving space 12 can buffer and store a certain amount of liquid.

[0053] In some embodiments, a control valve is also provided on the third pipeline 510, wherein the control valve is used to control the discharge of liquid from the third pipeline 510 into the accommodating space 12 and the gap 5100. The addition of the control valve can flexibly and more accurately control the volume of liquid dispensed into the accommodating space 12.

[0054] like Figure 8 and Figure 9 As shown, Figure 9 yes Figure 6 The third embodiment shows an exploded structural diagram of the connection part being separated. A first opening 2000 and a second opening 2001 are provided on the first connection part 200. A first pipe 500 passes through the accommodating space 12 through the first opening 2000. A third pipe 510 connects to the second opening 2001, and the liquid in the third pipe 510 enters the accommodating space 12 through the second opening 2001. In some embodiments, the first opening 2000 and the second opening 2001 penetrate the first connection part 200, and the first pipe 500 passes through the first opening 2000 to enter the accommodating space 12, while the third pipe 510 connects to the opening of the second opening 2001 and does not enter the accommodating space 12, thereby separating the supply and suction.

[0055] like Figure 8 and Figure 9 As shown, the connecting component 20 also includes a third connecting part 202. The third connecting part 202 is disposed on the side of the first connecting part 200 opposite to the second connecting part 201. The third connecting part 202 is used to fix the first pipe 500 and the third pipe 510. In some embodiments, the first opening 2000 and the second opening 2001 pass through the third connecting part 202. The third connecting part 202 is provided with a fixing groove that matches the size of the first pipe 500 and the third pipe 510, so that the first pipe 500 and the third pipe 510 will not be offset in position when they are working.

[0056] like Figure 10 , Figure 11 and Figure 13 As shown, Figure 10 yes Figure 6 Schematic diagram of the exploded structure of the second liquid storage component separation in the embodiment. Figure 11 yes Figure 7 An enlarged structural diagram of the embodiment at point A. Figure 13 yes Figure 7Another partial cross-sectional view of the embodiment shows that, in order to make the connection between the washing components more stable and to configure the liquid dispensing method more flexible, the housing assembly 10 also includes a first fixing member 40 and a second fixing member 910; wherein, the first fixing member 40 is disposed at the top end of the second pipe 11 on the side opposite to the connecting assembly 20, and the first fixing member 40 is the nozzle of the second pipe 11, and also serves to fix the first pipe 500; in some embodiments, the first fixing member 40 is provided with a second channel 410 and a third channel 411; wherein the second channel 410 The gap 5100 and the third channel 411 are connected. The third channel 411 is located on the side of the second channel 410 away from the gap 5100. There is a certain distance between the second channel 410 and the first pipe 500, that is, the second channel 410 and the first pipe 500 are not in close contact. The third channel 411 and the first pipe 500 are in close contact. The first pipe 500 enters the second liquid storage device 60 through the third pipe 510. The second channel 410 is used to discharge the liquid from the third pipe 510. At the same time, the third channel 411 is used to fix the first pipe 500. To ensure that the liquid can be evenly discharged from the second channel 410, an outlet 30 is provided on the outer wall of the first fixing member 40. The outlet 30 connects the second channel 410 and the second liquid storage member 60 outside the first fixing member 40. Multiple outlets 30 are provided on the outer wall of the first fixing member 40 so that the liquid in the second pipeline 11 can be evenly discharged through the second channel 410. At the same time, the outlets 30 can be flexibly set so that the first fixing member 40 can be flexibly adjusted according to the liquid discharge requirements. Making the third channel 411 and the first pipeline 500 in close contact can prevent the liquid supplied by the third pipeline 510 from contacting the suction port of the first pipeline 500 and causing contamination before entering the second liquid storage member 60.

[0057] like Figure 10 As shown, the second fixing member 910 is disposed between the connecting assembly 20 and the second pipeline 11, and the first fixing member 40 is used to fix the second pipeline 11. In some embodiments, the first fixing member 40 and the second fixing member 910 are fixed to the second pipeline 11 by heat shrink tubing. Firstly, PTFE heat shrink tubing is a hydrophobic and corrosion-resistant material, and using PTFE heat shrink tubing for heat shrink fixing can reduce the liquid residue between pipelines.

[0058] like Figure 14 , Figure 15 and Figure 16 As shown, Figure 14 This is a schematic diagram of the structure of the volume-regulating washing and transfer device according to an embodiment of this application.

In some embodiments, the volume-fixing and rinsing transfer device 2 further includes a housing with an opening and closing component. When volume fixing is required, the opening and closing component opens, and the clamping component 81 clamps the third liquid storage container 62 to be fixed to the fixing component 910. After the opening and closing component closes, the camera moving component 930 drives the camera component 931 to observe the volume fixing. Manual or automatic liquid addition can be performed until the volume fixing mark is reached. After the volume fixing is completed, the opening and closing component opens, the clamping component 810 clamps the third liquid storage container 62 back to the test tube receiving surface, and then the transfer component 650 is moved into the third liquid storage container 62, and the mixing component 80 is used to mix it.

[0059] like Figure 17 As shown, Figure 17 This is a schematic flowchart of a sample washing, transfer, and volume-adjusting method according to an embodiment of this application.

[0060] S101 Step 2: The transfer drive 651 is activated to transfer the washing solution and sample mixture in the second reservoir 60 to the transfer unit 650, and then to the third reservoir 62 through the transfer unit 650; in some embodiments, the transfer drive 651 transfers the washing solution and sample mixture in the second reservoir 60 after washing through the second pipeline 11 in the washing unit 640.

[0061] S102 The rinsing moving part 6412 moves the rinsing part 640 to the first cleaning part 82 for cleaning, and the transfer driving part 651 drives the transfer part 650 into the second cleaning part 83 for cleaning.

[0062] Step 3 of S103: After the sample transfer is completed, volume adjustment is performed. The clamping assembly 81 transfers the third liquid storage unit 62 to the fixing unit 910. The volume adjustment light source 922 is turned on and the camera 931 locates the graduation line of the third liquid storage unit 62. The volume adjustment drive 921 drives the volume adjustment unit 920 to add volume adjustment liquid into the third liquid storage unit 62. The camera 931 observes the liquid level position in real time, automatically judges the distance between the liquid level and the graduation line, and adjusts the liquid addition speed in real time. When the depression of the liquid level in the third liquid storage unit 62 is tangent to the graduation line, the liquid addition is stopped.

[0063] Step 4 of S104: The clamping assembly 81 clamps the third liquid storage unit 62 after it has been brought to a fixed volume onto the test tube placement surface 700. The transfer moving part 6521 drives the transfer part 650 to move to the third liquid storage unit 62. The mixing valve 801 is switched and the mixing drive part 800 is started to mix the mixed liquid in the third liquid storage unit 62.

[0064] S105 The rinsing moving part 6412 moves the rinsing part 640 to the first cleaning part 82 for cleaning, and the transfer driving part 651 drives the transfer part 650 into the second cleaning part 83 for cleaning.
