[0023] The present application embodiment provides a sample box displacement state detection device, such as Figures 1 to 3 The sample box displacement state detection device includes a socket sleeve 10, two beam sensors and an electric control device 30.
[0024] Both ends of the bell-and-spigot pipe 10 are used to be connected to the delivery pipe 60. Specifically, the ends of the two delivery pipes 60 are respectively inserted into the bell-and-spigot pipe 10 from both ends thereof.
[0025] Both through-beam sensors are mounted radially on the socket 10, with their axes coinciding. The two through-beam sensors include a light-emitting sensor 20a and a light-receiving sensor 20b. The light-emitting sensor 20a emits light, while the light-receiving sensor 20b receives the light emitted by the light-emitting sensor 20a. When the sample box 70 passes through the socket 10, the sample box 70 blocks the light emitted by the light-emitting sensor 20a. It should be noted that the light emitted by the light-emitting sensor 20a can be either visible or invisible light.
[0026] Exemplarily, both of the two opposing beam sensors are optical fiber sensors, which can achieve microsecond-level detection and can quickly detect the fast-moving sample box 70 .
[0027] The electronic control device 30 is electrically connected to the light emitting sensor 20a and the light receiving sensor 20b, and is configured to control the light emitting sensor 20a to emit light, receive signals from the light receiving sensor 20b, and determine whether the sample box 70 has passed through the socket 10 based on the signals from the light receiving sensor 20b. For example, the electronic control device 30 may be a programmable logic controller.
[0028] When the sample box displacement state detection device is in operation, the electronic control device 30 controls the light emitting sensor 20a to emit light, and the light receiving sensor 20b receives the light and transmits the signal to the electronic control device 30. When the sample box 70 moves in the conveying pipe 60 and passes through the bell-and-spigot 10, the sample box 70 blocks the light emitted by the light emitting sensor 20a, and the light receiving sensor 20b sends an interrupt signal. After receiving the interrupt signal from the light receiving sensor 20b, the electronic control device 30 can determine that the sample box 70 has passed through the bell-and-spigot 10. Therefore, the sample box displacement state detection device can detect the displacement state of the sample box 70.
[0029] like Figure 1 As shown, in the embodiment of the present application, the bell-and-spigot socket 10 includes a sleeve 11 and two fixed tubes 12. Both ends of the sleeve 11 are used to connect to the delivery pipe 60. The sleeve 11 has two first through holes 14 radially defined therein, with the axes of the two first through holes 14 coinciding. The two fixed tubes 12 are connected to the sleeve 11 and aligned with the two first through holes 14, respectively. A light-emitting sensor 20a and a light-receiving sensor 20b are respectively mounted within the two fixed tubes 12.
[0030] like Figure 2As shown, when the sample box 70 does not pass through the sleeve 11, the light emitted by the light sensor 20a passes through the inner cavity of the socket sleeve 10 and is received by the light receiving sensor 20b, which sends a signal to the electronic control device 30; Figure 3 As shown, when the sample box 70 passes through the sleeve 11 , the sample box 70 blocks the light emitted by the light-emitting sensor 20 a , the light-receiving sensor 20 b cannot receive the light, and the light-receiving sensor 20 b sends an interrupt signal to the electronic control device 30 .
[0031] For example, Figure 1 As shown, one end of the two fixing tubes 12 is installed in the two first through holes 14 respectively, and the light emitting sensor 20 a and the light receiving sensor 20 b are inserted and fixed from the other ends of the two fixing tubes 12 respectively.
[0032] Further, continue to refer to Figure 1 The socket sleeve 10 also includes a positioning ring 13, which is coaxially arranged on the inner wall of the sleeve 11. The positioning ring 13 is provided with two second through holes 15 corresponding to the two first through holes 14 respectively; and the thickness of the positioning ring 13 is equal to the thickness of the conveying pipe 60.
[0033] When the ends of the two delivery pipes 60 extend into the cannula 11 from either end, they abut against the end surface of the positioning ring 13. The positioning ring 13 positions the delivery pipes 60 relative to the cannula 11, preventing the two delivery pipes 60 from blocking the light-emitting sensor 20a and the light-receiving sensor 20b. Furthermore, the positioning ring 13 is equal in thickness to the delivery pipes 60, enabling the sample cartridge 70 to pass smoothly through the positioning ring 13.
[0034] Exemplarily, the positioning ring 13 is integrally connected to the sleeve 11 .
[0035] like Figure 2 and Figure 3 As shown, the sample box displacement state detection device provided in the embodiment of the present application further includes an indicator light 40, which is electrically connected to the electronic control device 30; wherein, when the electronic control device 30 receives an interrupt signal from the light receiving sensor 20b, it controls the indicator light 40 to light up.
[0036] A plurality of sample box displacement state detection devices are installed on the conveying pipe 60 , and the staff can determine the movement route and current position of the sample box 70 by observing the indicator light 40 . Figure 2 It shows that when the sample box 70 moves in the conveying pipe 60 and does not pass through the socket 10, the two beam sensors do not detect the sample box 70, and the indicator light 40 is off; Figure 3It shows that when the sample box 70 passes through the socket 10, the two through-beam sensors detect the sample box 70, and the electric control device 30 controls the indicator light 40 to light up.
[0037] Because the sample cartridge 70 moves rapidly within the delivery conduit 60, to facilitate detection of the sample cartridge 70, the electronic control device 30 is configured to initiate a shutdown delay when receiving an interrupt signal from the light sensor 20b. The shutdown delay refers to the time between when the electronic control device 30 no longer receives the interrupt signal and when it actually shuts off the indicator light 40. During this time, the indicator light 40 remains operational until the delay expires.
[0038] like Figure 1 As shown, the sample cartridge displacement state detection device provided in the embodiment of the present application further includes a sealing ring 50, which is mounted on the inner wall of the bell-and-spigot 10 and is used to seal the bell-and-spigot 10 and the delivery pipe 60. Since the sample cartridge 70 is propelled in the delivery pipe 60 by airflow, the sealing ring 50 can prevent air leakage between the bell-and-spigot 10 and the delivery pipe 60, ensuring that the sample cartridge 70 can pass smoothly through the bell-and-spigot 10.
[0039] The sample box displacement state detection device provided in the embodiment of the present application also includes two lenses, which are respectively arranged in the two second through holes 15. The side surfaces of the two lenses are respectively close to the inner walls of the two second through holes 15, and the inner end faces of the two lenses are arc surfaces and are coaxially arranged with the inner wall surface of the positioning ring 13.
[0040] Light emitted by luminescence sensor 20a passes through two lenses and is then received by light-receiving sensor 20b. These two lenses isolate second through-hole 15 and the inner cavity of fixed tube 12 from the inner cavity of cannula 11. This prevents the airflow that propels sample cartridge 70 from entering second through-hole 15 and fixed tube 12, thus preventing gas from leaking from fixed tube 12. Furthermore, this prevents airflow from entering second through-hole 15 and fixed tube 12 and affecting the movement of sample cartridge 70.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
