In use, the fecal sample to be tested is stored in a sampling tube on the sample rack 2, and the sample propulsion component 3 drives the sample rack 2 to move on the base 1, thereby realizing the automatic injection of the fecal sample to be tested.

[0031] Based on the above structure, the automatic sample introduction module arranges the sample rack 2 in an orderly manner on the base 1, and drives the sample rack 2 to move through the sample propulsion component 3, so as to realize the automatic introduction of the fecal sample to be tested, ensuring the orderliness and automation of the sample introduction operation, shortening the time of the sample introduction process, and improving the processing efficiency.

[0032] like Figure 4 As shown, in some embodiments of this application, the sample propulsion component 3 includes a first driving member 31 and a first deflector 32 connected to the first driving member 31. The first driving member 31 is used to drive the first deflector 32 to move, thereby driving the sample holder 2 to move, so as to realize the automatic injection of the fecal sample to be tested. The injection process does not require manual intervention, ensuring the accuracy and efficiency of fecal sample transmission.

[0033] Specifically, the first driving component 31 uses mechanical structures such as worm gear, motor transmission, and electric telescopic rod to drive the first lever 32 to move.

[0034] In some embodiments of this application, the automatic sample feeding module further includes a sample pushing component 4, which is disposed on a base 1 at the front end of the sample pushing component 3, and is used to move the sample holder 2 to the sample pushing component 3.

[0035] like Figure 2 As shown, in some embodiments of this application, the sample pushing component 4 includes a second driving member 41 disposed on the base 1 and a second dial plate 42 and a sensing member 43 connected to the second driving member 41. The sensing member 43 is used to detect whether there is a sample holder 2.

[0036] In this embodiment, the sensing element 43 is specifically a through-beam photoelectric switch, a reflective photoelectric switch, etc. The second driving element 41 uses a mechanical structure such as a worm gear, motor transmission, and electric telescopic rod to drive the second dial plate 42 to move. The user places multiple sample racks 2 on the base 1 and detects the presence of sample racks 2 through the sensing element 43. When a sample rack 2 is present, the sensing element 43 sends the detection result to the control terminal of the second driving element 41, controlling the second driving element 41 to start, driving the second dial plate 42 to move, and thus driving the sample racks 2 to move.

[0037] like Figure 2 , Figure 3 As shown, in some embodiments of this application, the base 1 is provided with a positioning protrusion 11 extending along the moving direction of the second lever 42, and the bottom of the sample holder 2 is provided with a positioning groove 21 that cooperates with the positioning protrusion 11.

[0038] In this embodiment, the positioning protrusion 11 is accommodated in the positioning groove 21 to prevent the sample holder 2 from shifting when it moves under the action of the second lever 42, thus ensuring the stability of the sample holder 2 when it moves.

[0039] In some embodiments of this application, the base 1 is further provided with a positioning plate 12 extending along the moving direction of the second lever 42, and the sample rack 2 is provided with a positioning groove 22 that cooperates with the positioning plate 12.

[0040] In this embodiment, the positioning groove 22 is located on the side of the sample rack 2, and the positioning plate 12 is positioned in a position corresponding to the positioning groove 22. The positioning plate 12 is inserted into the positioning groove 22, and the positioning protrusion 11 is accommodated in the positioning groove 21, which can further ensure the stability of the sample rack 2 when it moves.

[0041] In some embodiments of this application, the automatic sample introduction module further includes a sample ejection component 5, which is disposed on the base 1 at the rear end of the sample propulsion component 3. The sample ejection component 5 is used to move the sample rack 2 outside the automatic sample introduction module to avoid the sample rack 2 from accumulating on the sample propulsion component 3 and hindering the subsequent propulsion of the sample rack 2, thereby improving the efficiency of the sample rack 2 propulsion.

[0042] like Figure 5 As shown, in some embodiments of this application, the sample ejection component 5 includes a third drive member 51 and a third dial plate 52 connected to the third drive member 51. The third drive member 51 is used to drive the third dial plate 52 to move, thereby driving the sample holder 2 to move.

[0043] Specifically, the third drive component 51 uses mechanical structures such as worm gear, motor transmission, and electric telescopic rod to drive the third lever 52 to move.

[0044] In some embodiments of this application, the sample ejection component 5 further includes a sensor, which is disposed at one end of the third dial 52 on the forward path away from the sample push component 3. The sensor is a through-beam photoelectric switch, a reflective photoelectric switch, etc. When the sensor detects a sample rack, it indicates that the sample ejection component 5 is full of sample racks 2, reminding the user to remove the sample racks 2 piled on the sample ejection component 5.

[0045] In some embodiments of this application, the first driving component 31 includes a mounting plate 311, a drive motor 312, a driving wheel 313, a driven wheel 314, and a conveyor belt 315. The mounting plate 311 is disposed on the base 1. The drive motor 312, the driving wheel 313, and the driven wheel 314 are disposed on the mounting plate 311. The output shaft of the drive motor 312 is connected to the axis of the driving wheel 313. The driving wheel 313 is connected to the driven wheel 314 through the conveyor belt 315. The conveyor belt 315 is connected to the first lever 32.

[0046] The first driving member 31, the second driving member 41 and the third driving member 51 may have the same or different structures. When the three driving members have the same structure, the conveyor belt 315 in the second driving member 41 is connected to the second dial plate 42, and the conveyor belt 315 in the third driving member 51 is connected to the third dial plate 52.

[0047] In this embodiment, the first baffle 32, the second baffle 42, and the third baffle 52 are all fixedly connected to the conveyor belt 315. When in use, the drive motor 312 starts, driving the drive wheel 313 and the driven wheel 314 to rotate, which in turn drives the conveyor belt 315 and the first baffle 32, the second baffle 42, and the third baffle 52 to move, pushing the sample holder 2 that is in contact with the first baffle 32, the second baffle 42, and the third baffle 52 to move, thereby realizing the pushing, pushing, and pushing out of the fecal sample to be tested.

[0048] Specifically, the first baffle plate 32, the second baffle plate 42, and the third baffle plate 52 are connected to the conveyor belt 315 via connectors. In order to improve the stability of the movement of the first baffle plate 32, the second baffle plate 42, and the third baffle plate 52, a guide rail is provided on the mounting plate 311, and a guide block that cooperates with the guide rail is provided on the connector.

[0049] The specific method for using the automatic sample injection module provided in this embodiment is as follows:

[0050] Before use, the user places the sampling tube containing the fecal sample on the sample rack 2, and then arranges multiple sample racks 2 sequentially on the base 1. The positioning plate 12 on the side of the base 1 is accommodated in the positioning groove 22 on the side of the sample rack 2, and the positioning protrusion 11 on the base 1 is accommodated in the positioning groove 21. The sensor 43 is activated to detect whether there is a sample rack 2 on the base 1. If there is, the sensor 43 sends the detection result to the control terminal of the second drive unit 41, which controls the drive motor 312 in the second drive unit 41 to start, drive the active wheel 313 and the driven wheel 314 to rotate, and then drive the conveyor belt 315 and the second baffle 42 to move, pushing the sample rack 2 to the sample propulsion assembly 3.

[0051] When the drive motor 312 in the sample propulsion assembly 3 starts, it drives the drive wheel 313 and the driven wheel 314 to rotate, which in turn drives the conveyor belt 315 and the first baffle 32 to move, pushing the sample holder 2 to the sample ejection assembly 5; when the drive motor 312 in the sample ejection assembly 5 starts, it drives the drive wheel 313 and the driven wheel 314 to rotate, which in turn drives the conveyor belt 315 and the third baffle 52 to move, pushing the sample holder 2 to the outside of the automatic sample feeding module, thereby realizing the automatic feeding and ejection of the fecal sample to be tested and improving the efficiency of fecal analysis.
