The tray structure 20 is mounted on the support frame 10 and has a consumable carrying area. The recycling structure 30 is adjacent to the support frame 10 and includes a frame 31, a mounting beam 32 movably mounted on the frame 31, and a drive structure 33 mounted on the frame 31 and driving the mounting beam 32. The mounting beam 32 has multiple recycling rods 34 spaced horizontally, each recycling rod 34 having an airflow channel.

The width of the notch structure 41 is greater than the diameter of the recovery rod 34. The mounting beam 32 has a working position that cooperates with the support plate structure 20 and a separating position that cooperates with the peeling structure 40. When the mounting beam 32 is in the working position, the recovery rod 34 and the support plate structure 20 can move closer or further apart.

The above structure saves the space occupied by the consumable recycling device, and improves the space utilization rate of the nucleic acid detection analyzer.

[0039] It should be noted that the mounting beam 32 can move between the stripping structure 40 and the supporting plate structure 20, so that the mounting beam 32 can be switched between the working position and the separation position.

[0040] It should be further noted that in the embodiment, one of the magnetic rod sleeve 90 or the recycling rod 34 is provided with a clamping groove, and the other is provided with a clamping protrusion, the recycling rod 34 extends into the magnetic rod sleeve 90 and presses the magnetic rod sleeve 90, and the magnetic rod sleeve 90 is connected with the recycling rod 34 in a clamping manner. Of course, in other embodiments, the magnetic rod sleeve 90 and the recycling rod 34 can also be inserted together in an interference fit. Specifically, as Figure 1 and Figure 2As shown, in this embodiment, the peeling structure 40 and the pallet structure 20 are spaced apart in a first preset direction. The opening of the notch structure 41 faces the pallet structure 20. The frame 31 includes a fixed plate 311 and a movable plate 312 movably disposed on the fixed plate 311 along the first preset direction. The mounting beam 32 is movably disposed on the movable plate 312 along the vertical direction. The driving structure 33 includes a horizontal driving structure 331 and a vertical driving structure 332. The horizontal driving structure 331 is disposed between the fixed plate 311 and the movable plate 312 to drive the movement of the movable plate 312. The vertical driving structure 332 is disposed between the movable plate 312 and the mounting beam 32 to drive the movement of the mounting beam 32. In the above structure, the horizontal driving structure 331 of the driving structure 33 can drive the mounting beam 32 to move in the first preset direction, thereby enabling the mounting beam 32 to move between the working position and the separation position. The mounting beam 32 is mounted on the movable plate via a vertical drive structure 332. The vertical drive structure 332 can move the mounting beam 32 vertically, allowing the recovery rod 34 to extend into and out of the nucleic acid extraction plate 100. It also drives the movement of the recovery rod 34, enabling cooperation between the recovery rod 34 and the stripping structure 40. This structure is simple, provides stable drive, and helps improve the automation level of the consumable recycling device.

[0041] like Figure 2 As shown, in this embodiment, the support frame 10 includes a guide shell 11 and a vertical plate 12 disposed on the side of the guide shell 11. The guide shell 11 has a recycling channel, a peeling structure 40 is disposed at the inlet of the recycling channel, and a support plate structure 20 is disposed on the vertical plate 12. In the above structure, the guide shell 11 has a recycling channel, and the peeled magnetic rod sleeve 90 can slide down along the recycling channel into the collection box for centralized recycling, which facilitates subsequent processing of the magnetic rod sleeve 90.

[0042] It should be noted that the support frame 10 can be an integral structure or a separate structure. In this embodiment, the upright plate 12 and the guide shell 11 are set separately, and the support frame 10 is a separate structure. Of course, in other embodiments, the upright plate 12 and the guide shell 11 can also be an integral structure, that is, the upright plate 12 and the guide shell 11 are connected.

[0043] like Figure 1 and Figure 3As shown in the embodiment, the tray structure 20 is movably arranged on the bearing plate 12 in the vertical direction, and the consumable recycling device further comprises a separation frame 50 arranged on the bearing frame 10, and the separation frame 50 is provided with a avoiding hole through which the tray structure 20 passes downward. In the above structure, after the magnetic rod sleeve 90 in the nucleic acid extraction plate 100 and the waste liquid recycling are completed, the tray structure 20 can be driven to move downward until the tray structure 20 passes downward from the avoiding hole of the separation structure, and the nucleic acid extraction plate 100 can be left on the separation frame 50, thereby facilitating the recycling of the nucleic acid extraction plate 100.

[0044] As shown in the embodiment, Figure 1 , Figure 3 and Figure 4 , the consumable recycling device further comprises a stop structure 60 movably arranged on the vertical plate 12, the stop structure 60 has a stop position below the tray structure 20 and an avoiding position staggered with the tray structure 20, and when the mounting beam 32 is in the working position, the stop structure 60 is in the stop position to support the tray structure 20. In the above structure, since the recycling rod 34 needs to press the magnetic rod sleeve 90 downward when connecting the magnetic rod sleeve 90, so that the magnetic rod sleeve 90 is fixed on the recycling rod 34 in interference, the tray structure 20 needs to bear the pressure of the recycling rod 34. The present application provides the stop structure 60 on the vertical plate 12, and when the mounting beam 32 is in the working position, the stop structure 60 is in the stop position to support the tray structure 20, thereby ensuring the bearing capacity of the tray structure 20.

[0045] Specifically, as shown in the embodiment, Figure 1 , Figure 3 and Figure 4 , the stop structure 60 comprises a driving motor 61 arranged on the vertical plate 12 and a swing piece 62, the first end of the swing piece 62 is drivingly connected with the pivot shaft of the driving motor 61, the second end of the swing piece 62 has a stop position and an avoiding position, and the driving motor 61 can drive the second end of the swing piece 62 to move between the stop position and the avoiding position. In the above structure, the driving motor 61 can drive the swing piece 62 to swing, when the recycling rod 34 is connected with the magnetic rod sleeve 90, the second end of the swing piece 62 is first rotated to the stop position, then the tray structure 20 is abutted with the second end of the swing piece 62, and then the recycling operation of the magnetic rod sleeve 90 can be started. When the recycling of the magnetic rod sleeve 90 in the nucleic acid extraction plate 100 and the waste liquid is completed, the second end of the swing piece 62 can be driven to rotate to the avoiding position, at this time, the tray structure 20 can move downward and leave the nucleic acid extraction plate 100 on the separation frame 50, thereby recycling the nucleic acid extraction plate 100. As shown in the embodiment, Figure 1 , Figure 3 and Figure 4As shown in the drawings, in this embodiment, the driving motor 61 is arranged on the vertical plate 12, and the vertical plate 12 is further provided with an arc-shaped guide groove 121, and the second end of the swing piece 62 is provided with a support rod 621 which can slide in the arc-shaped guide groove 121. In the above structure, the arc-shaped guide groove 121 can guide the movement of the second end of the swing piece 62, so that the second end of the swing piece 62 can stably move between the stop position and the avoiding position.

[0046] It should be noted that the driving motor 61 and the supporting plate structure 20 are located on the first side of the vertical plate 12, the rotating shaft of the driving motor 61 penetrates the vertical plate 12 and extends to the second side of the vertical plate 12, the first end of the swing piece 62 is located on the second side of the vertical plate 12 and is drivingly connected with the rotating shaft of the driving motor 61, the second end of the swing piece 62 is provided with the support rod 621, the support rod 621 penetrates to the first side of the vertical plate 12 through the arc-shaped guide groove 121, and forms a stop cooperation with the supporting plate structure 20.

In the above structure, the pushing structure can push the nucleic acid extraction plate 100 on the separating frame 50 away from the separating frame 50, which can facilitate recycling of the nucleic acid extraction plate 100, and can also empty the position on the separating frame 50, thereby facilitating recycling of the subsequent nucleic acid extraction plate 100.

[0048] As shown in the drawings, Figure 3 In this embodiment, the supporting plate structure 20 is provided with a limiting structure for limiting the consumable. In the above structure, the limiting structure can increase the stability of the nucleic acid extraction plate 100 placed on the supporting plate structure 20.

[0049] As shown in the drawings, Figure 3 In this embodiment, the limiting structure comprises a plurality of limiting columns 71 arranged on the supporting plate structure 20. The plurality of limiting columns 71 can be inserted and matched with the insertion holes at the bottom of the nucleic acid extraction plate 100, so that the nucleic acid extraction plate 100 can be stably fixed on the supporting plate structure 20.

[0050] As shown in the drawings, Figure 3 In this embodiment, the limiting structure further comprises a magnetic attraction structure 72 arranged on the supporting plate structure 20. In the above structure, the magnetic attraction structure 72 can be magnetically attracted to the magnetic beads in the nucleic acid extraction plate 100, so that the magnetic beads can be adsorbed at the bottom of the nucleic acid extraction plate 100, preventing the magnetic beads from blocking the air flow channel of the recycling rod 34 when the recycling rod 34 sucks the waste liquid in the nucleic acid extraction plate 100.

[0051] AsFigure 1 and Figure 2 As shown in FIG. 13, in the embodiment, the recovery rod 34 includes a first rod section 341 connected with the mounting beam 32 and a second rod section 342 located below the first rod section 341, the diameter of the first rod section 341 is larger than that of the second rod section 342, a variable diameter portion with a diameter gradually decreasing from top to bottom is arranged on the first rod section 341, and the airflow channel penetrates through the first rod section 341 and the second rod section 342. In the above structure, since the recovery rod 34 needs to be connected with the magnetic rod sleeve 90, the diameter of the first rod section 341 is set to be larger and the variable diameter portion is arranged on the first rod section 341, so that the magnetic rod sleeve 90 can be inserted on the recovery rod 34. The diameter of the second rod section 342 is set to be smaller, so that the second rod section 342 can smoothly extend into the nucleic acid extraction plate 100.

[0052] As shown in FIG. 14, it is also needed to be explained that the bottom of the second rod section 342 is provided with a plurality of notches 3421, so that when the bottom of the second rod section 342 is in contact with the inner wall of the nucleic acid extraction plate 100, the airflow channel will not be blocked, thereby ensuring that the waste liquid in the nucleic acid extraction plate 100 can be completely sucked. Figure 6 The application also provides a nucleic acid detection analyzer, and an embodiment of the nucleic acid detection analyzer includes a consumable recovery device, and the consumable recovery device is the above-described consumable recovery device. In the above structure, since the consumable recovery device has the advantages of high integration and small space occupation, the nucleic acid detection analyzer with the consumable recovery device also has the above advantages.
