[0041] like Figure 1-Figure 3 As shown, an enzyme detection sampler includes a fixing seat 1, a fixing tube 2, a telescopic tube 3, and an adjusting mechanism.

[0042] A first flow channel 19 for the target liquid (the target liquid in this article refers to the culture liquid containing superoxide dismutase in the culture tank) to flow is formed in the fixing seat 1.

[0043] The fixed pipe 2 is detachably connected to the fixed seat 1, such as being threadedly connected to the fixed seat 1. After the fixed top pipe is removed from the fixed seat 1, it is convenient to subsequently clean the first flow channel 19 in the fixed seat 1 and the interior of the fixed pipe 2.

[0044] The telescopic tube 3 is slidably connected to the fixed tube 2 and partially extends to the outside of the fixed tube 2. A second flow channel 20 for the target liquid to flow is formed in the telescopic tube 3. When the fixed tube 2 is connected to the fixed seat 1, the second flow channel 20 is connected to the first flow channel 19.

[0045] The adjustment mechanism includes an adjustment motor 4, an adjustment screw 5, and an adjustment seat 6. The adjustment motor 4 is connected to the fixed seat 1 and is located on the side of the fixed seat 1 away from the fixed tube 2. One end of the adjustment screw 5 is connected to the motor shaft of the adjustment motor 4, and the other end extends into the fixed tube 2, and the adjustment screw 5 is rotatably connected to the fixed seat 1 through a bearing; the adjustment seat 6 is slidably connected to the telescopic tube 3, and a threaded hole is provided on the adjustment seat 6, and the thread passes through the adjustment seat 6 along the axial direction of the fixed tube 2. The adjustment screw 5 is threadedly connected to the threaded hole, so that the adjustment seat 6 is threadedly connected to the adjustment screw 5.

[0046] When the adjustment motor 4 is working, the motor shaft drives the adjustment screw 5 to rotate, so that the adjustment seat 6 drives the telescopic tube 3 to slide relative to the fixed tube 2, thereby adjusting the length of the telescopic tube 3 located outside the fixed tube 2, so that the end of the telescopic tube 3 away from the fixed seat 1 can be extended to the target depth position of the superoxide dismutase culture solution in the culture tank. When the vacuum device is working, the vacuum device reduces the pressure in the first flow channel 19, the inside of the fixed tube 2 and the second flow channel 20, so that the target liquid can enter the first flow channel 19 through the second flow channel 20 and the inside of the fixed tube 2 in turn to complete the sampling of the target liquid.

[0047] In one embodiment of the present application, a sealing surface 22 is provided on the fixing seat 1, and the sealing surface 22 is provided on a side of the fixing seat 1 close to the fixing tube 2. When the enzyme detection sampler is inserted into the culture tank through the sampling port of the culture tank for sampling, the sealing surface 22 abuts against the sampling port, so that the enzyme detection sampler seals the sampling port when sampling.

[0048] Along the axial direction of the fixed tube 2, the cross-sectional area of ​​the sealing surface 22 is gradually increased, and the cross-sectional area of ​​the sealing surface 22 away from the end of the fixed tube 2 is larger than the cross-sectional area of ​​the sealing surface 22 close to the end of the fixed tube 2. In one embodiment of the present application, the shape of the sealing surface 22 is circular. By gradually increasing the cross-sectional area of ​​the sealing surface 22, the sealing surface 22 can adapt to sampling ports of various sizes.

[0049] In one embodiment of the present application, when the adjustment seat 6 is cylindrical or disc-shaped, the adjustment mechanism further includes a limiting rod 7 .

[0050] Specifically, the limiting rod 7 is connected to a side of the fixing seat 1 close to the fixing tube 2 and extends into the fixing tube 2. Along the radial direction of the adjusting seat 6, the limiting rod 7 and the adjusting screw rod 5 are arranged in parallel and spaced apart. The adjusting seat 6 is provided with a limiting hole. The limiting hole penetrates the adjusting seat 6 axially along the fixing tube 2, and the limiting hole and the threaded hole are arranged at radial intervals along the adjusting seat 6. The limiting rod 7 is slidably connected in the limiting hole so that the adjusting seat 6 is slidably connected to the limiting rod 7 to prevent the adjusting seat 6 from rotating in the fixing tube 2.

[0051] In one implementation of the present application, the adjustment mechanism further includes a first limiting block 8 .

[0052] The first stopper 8 is connected to the end of the adjusting screw 5 away from the fixing seat 1, and the radial dimension of the first stopper 8 is greater than the radial dimension of the adjusting screw 5. When the adjusting seat 6 moves to the end of the adjusting screw 5 away from the fixing seat 1, the first stopper 8 is arranged at the end of the adjusting screw 5 away from the fixing seat 1 to prevent the adjusting seat 6 from falling off the adjusting screw 5.

[0053] In one implementation of the present application, the enzyme detection sampler further includes a switch mechanism connected to the side wall of the fixing seat 1 , the first flow channel 19 is provided with a first flow channel outlet 23 , and the switch mechanism is used to open or close the first flow channel outlet 23 .

[0054] Specifically, in the present application, the switch mechanism includes an adapter 9, a second limit block 13 and a driving handle 17. A connecting seat 18 is provided on the fixing seat 1, a first flow channel 19 is located in the connecting seat 18, and a first flow channel outlet 23 is provided on the first flow channel 19 and located in the connecting seat 18. The adapter 9 is threadedly connected to the first flow channel outlet 23 on the fixing seat 1. A third flow channel 21 is provided in the adapter 9, the third flow channel 21 is connected to the first flow channel 19 through the first flow channel outlet 23, and the third flow channel 21 is used to be connected to the vacuum device through a pipeline.

[0055] When the vacuum device is working, it reduces the pressure in the first flow channel 19, the interior of the fixed tube 2, the second flow channel 20, and the third flow channel 21, so that the target liquid enters the first flow channel 19 through the second flow channel 20 and the interior of the fixed tube 2 in sequence to complete the sampling of the target liquid.

[0056] The adapter 9 has an open position and a closed position, and a sealing groove 24 is provided in the first flow channel outlet 23. When the adapter 9 is in the open position, the adapter 9 is separated from the sealing groove 24, so that the third flow channel 21 is connected to the first flow channel outlet 23. When the adapter 9 is in the closed position, the adapter 9 abuts against the sealing groove 24, so that the sealing groove 24 closes the third flow channel 21.

[0057] The driving handle 17 is disposed on the adapter 9 and is used to drive the adapter 9 to rotate relative to the connecting seat 18 .

[0058] In one implementation of the present application, the adapter 9 is provided with a first abutting surface 11 in the shape of a truncated cone, wherein the cross-sectional area of ​​the first abutting surface 11 at one end close to the first flow channel liquid outlet 23 is smaller than the cross-sectional area of ​​the first abutting surface 11 at one end away from the first flow channel liquid outlet 23. The third flow channel liquid inlet 10 is provided on the first abutting surface 11.

[0059] The sealing groove 24 is provided with a second abutting surface 12 whose shape matches that of the first abutting surface 11. When the adapter 9 is in the closed position, the first abutting surface 11 abuts against the second abutting surface 12. The second abutting surface 12 closes the third flow channel liquid inlet 10. When the adapter 9 is in the open position, the first abutting surface 11 separates from the second abutting surface 12 to open the third flow channel liquid inlet 10, so that the third flow channel 21 is connected to the first flow channel 19 through the third flow channel liquid inlet 10.

[0060] In one embodiment of the present application, the adapter 9 is threadedly connected with a second limit block 13, and the second limit block 13 is protruded from the connecting member along the radial direction of the adapter 9. The connecting seat 18 is provided with a limit groove 14, and the limit groove 14 has a first limit end face 15 and a second limit end face 16; when the adapter 9 is in the open position, the second limit block 13 abuts against the first limit end face 15. When the adapter 9 is in the closed position, the second limit block 13 moves from the first limit end face 15 to the second limit end face 16 until the first abutting face 11 abuts against the second abutting face 12.

[0061] Working principle: When in use, the staff extends the enzyme detection sampler from the sampling hole into the culture tank, starts the adjustment motor 4 to drive the adjustment screw 5 to rotate, and the adjustment seat 6 threadedly connected to the adjustment screw 5 pushes the telescopic tube 3 to slide in the fixed tube 2 along the limit rod 7 under the action of the adjustment screw 5, until the end of the telescopic tube 3 away from the fixed seat 1 extends to the depth position of the superoxide dismutase culture solution to be sampled in the culture tank, and then rotates the drive handle 17 to make the adapter 9 in the open position, and the vacuum device starts to sample the superoxide dismutase culture solution at the target depth.

[0062] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
