[0053] Figure 1 A schematic diagram of the structure of a sample injection device for an analyzer system according to an embodiment of the present application is shown. Figure 2 A circuit block diagram of a sample injection device for an analyzer system according to an embodiment of the present application is shown.

[0054] See also Figure 1 and Figure 2 An embodiment of the present application provides a sample injection device for an analyzer system, wherein the analyzer system includes an analyzer body 10, and the analyzer body 10 includes a housing 110, a display screen 120, and a titration cell 130. The display screen 120 is provided on the housing 110 and is used to display a sample injection prompt message, indicating that the sample can be put into the titration cell 130 at this time.

[0055] Taking the analyzer system as a reducing sugar analyzer system as an example for description, the titration cell 130 is used to perform titration analysis of the sample to calculate the reducing sugar content of the sample.

[0056] The analyzer body 10 also includes a titration pump (not shown in the figure) and a photometric sensor (not shown in the figure), etc., and the analyzer system is used to determine the reducing sugar content as an example for explanation. When the sample is added to the titration cell 130, the titration pump drips a titration solution (such as Fehling's AB reagent) into the titration cell 130 until the titration reaction reaches the reducing sugar endpoint. When the titration reaction reaches the reducing sugar endpoint, the photometric sensor is used to determine that the titration reaction has reached the reducing sugar endpoint based on the detected absorbance jump information, and the titration pump is triggered to stop dripping the titration solution. The reducing sugar content of the sample can be calculated based on the volume of the consumed titration solution. The analyzer body 10 also includes a calculation module (not shown in the figure), which is used to calculate the reducing sugar content of the sample based on the volume of the consumed titration solution. The display screen 120 is electrically connected to the calculation module and is used to display the analysis result of the sample, that is, to display the reducing sugar content of the sample. Before the sample is added to the titration cell 130, the display screen 120 is also used to display the sample injection prompt information to indicate that the sample needs to be dripped into the titration cell 130 at this time.

[0057] The sample injection device includes a visual recognition device 20, a sample injection mechanism 30, a sample holder 41 and a controller 50. The sample holder 41 is provided with a sample tube 42 for accommodating a sample, and the sample injection mechanism 30 includes a sampling needle 310 located at the top side of the sample holder 41, and the sampling needle 310 is configured to absorb or release the sample in the sample tube 42.

[0058] The controller 50 is electrically connected to the visual recognition device 20 and the sample injection mechanism 30 respectively. The visual recognition device 20 is used to obtain the sample injection prompt information displayed on the display screen 120. The controller 50 is used to control the sample injection mechanism 30 to be in a starting state according to the sample injection prompt information obtained by the visual recognition device 20, so that the sampling needle 310 can extend into the sample tube 42 to be tested and absorb the sample in the sample tube 42, and the sampling needle 310 can release the absorbed sample into the titration cell 130.

[0059] The sampling needle 310 is configured to be able to absorb or release the sample in the sample tube 42. The sampling needle 310 can absorb the sample in the sample tube 42 by means of a negative pressure pump or other pumps, and when it is necessary to release it into the titration tank 130, the vacuum state of the sampling needle 310 is released or other pumps are reversed to press out the sample in the sample tube 42 to release the sample.

[0060] “The sampling needle 310 is configured to release the sucked sample into the titration cell 130 ”, which means that the sampling needle 310 is driven by a driving member to move into the titration cell 130 , and then the sample is released by a negative pressure pump or other pumps; or the sample is directly drawn into the titration cell 130 by a pump.

[0061] In this way, when the visual recognition device 20 receives the sample injection prompt information displayed on the display screen 120, it indicates that the sample can be added to the titration cell 130 at this time. At this time, the controller 50 is used to control the injection mechanism 30 to be in the starting state according to the sample injection prompt information obtained by the visual recognition device 20, so that the injection mechanism 30 is started, and then the sampling needle 310 can absorb the sample in the sample tube 42, and can release the absorbed sample to the titration cell 130, so that the analyzer system can measure the sample added to the titration cell 130. Therefore, the use of the injection device can realize automatic sample injection, which can save the on-duty personnel set for the injection prompt information, save manpower, and improve the automation level of the analyzer system.

[0062] In some embodiments, see Figure 1 and Figure 2 , and refer to Figure 3 The sample injection mechanism 30 further includes a lifting drive 320 and a rotating drive 330 electrically connected to the controller 50, respectively. The lifting drive 320 is connected to the sampling needle 310 to drive the sampling needle 310 to move along the first direction F1. The rotating drive 330 is connected to the lifting drive 320. The rotating drive 330 is used to drive the lifting drive 320 and the sampling needle 310 to rotate around a first preset axis parallel to the first direction F1, so as to rotate the sampling needle 310 to the top of the titration cell 130, the sample tube 42 or the cleaning tank 611 described below. The first direction F1 is parallel to the top of the sample holder 41 and points to the bottom of the sample holder 41.

[0063] Specifically, the first direction F1 is parallel to the up-down direction.

[0064] Specifically, the controller 50 includes a control module 530 electrically connected to the lifting driving member 320 and the rotating driving member 330 respectively.

[0065] Optionally, see Figure 1 and Figure 3The rotating driving member 330 includes a first rotating motor 331, and the sampling mechanism 30 also includes a first driving wheel 332, a first driven wheel 333 and a first belt 334. The first driving wheel 332 is arranged on the output end of the first rotating motor 331, and the first driven wheel 333 is connected to the first driven wheel 333 through the first belt 334. The first driven wheel 333 is connected to the sampling needle 310 through the second mounting seat 360, and the lifting driving member 320 is arranged on the second mounting seat 360.

[0066] Optionally, the sample injection mechanism 30 further includes a first mounting seat 335, a first rotary motor 331 is disposed on the first mounting seat 335, an output shaft of the first rotary motor 331 passes through the top of the first mounting seat 335, and is connected to the first driving wheel 332. The first driven wheel 333 is rotatably disposed on the first mounting seat 335 around the first rotation axis.

[0067] The lifting drive member 320 may include a motor or a cylinder. Specifically, the lifting drive member 320 includes a third driving motor 321 and a first screw rod 322 disposed on the output end of the third driving motor 321. The first screw rod 322 is used to convert the rotational motion of the output end of the third driving motor 321 into the linear motion of the sampling needle 310 along the first direction F1. The injection mechanism 30 also includes two guide rods 370 disposed on the second mounting seat 360. The sampling needle 310 is configured to be able to move relative to the guide rods 370 along the first direction F1, which is conducive to improving the stability of the sampling needle 310 moving along the first direction F1. The injection mechanism 30 also includes a needle seat 380, one end of the needle seat 380 is connected to the top of the sampling needle 310, and the other end of the needle seat 380 is slidably connected to the guide rod 370 along the first direction F1 and is threadedly connected to the first screw rod 322.

[0068] After the sampling mechanism 30 is started, if the sampling needle 310 is located above the sample tube 42, the sampling needle 310 can be driven to move downward along the first direction F1 by the lifting drive member 320, and then the sampling needle 310 can be driven to extend into the sample in the sample tube 42, and the sampling needle 310 can be used to absorb the sample, and then the sampling needle 310 can be driven to move upward along the first direction F1 by the lifting drive member 320, and then the lifting drive member 320 and the sampling needle 310 can be driven to rotate around the first preset axis by the rotating drive member 330, and then the sampling needle 310 can be rotated to the top of the titration cell 130, and then the sampling needle 310 can be driven to move downward along the first direction F1 by the lifting drive member 320 to extend into the titration cell 130, and then the sample absorbed by the sampling needle 310 is released into the titration cell 130 by the sampling needle 310, and thus the automatic sampling operation of the sample in the sample tube 42 is completed.

[0069] Of course, the present application is not limited to this. In other embodiments, the injection mechanism 30 may also include a pump for injection, one end of the pump is connected to the sampling needle 310, and the other end is connected to the titration cell 130, and the pump is electrically connected to the controller 50. When the visual recognition device 20 receives the sample injection prompt information displayed on the display screen 120, the controller 50 controls the operation of the pump, and the pump releases the sample in the sample tube 42 into the titration cell 130 through the sampling needle 310, and can also complete the automatic injection operation of the sample in the sample tube 42.

[0070] In some embodiments, see Figure 1 , and refer to Figure 4 The sampling device also includes a cleaning mechanism 60 for cleaning the sampling needle 310 . The cleaning mechanism 60 is located below the path of the sampling needle 310 rotating around the first preset axis, so that the rotary drive member 330 can drive the sampling needle 310 to rotate above the cleaning mechanism 60 .

[0071] Specifically, the sampling needle 310 has a sampling station, an injection station and a cleaning station arranged at intervals around a first preset axis. The sampling needle 310 also has a first station located at the top side of the sampling station along the first direction F1, a second station located at the top side of the injection station along the first direction F1, and a third station located at the top side of the cleaning station along the first direction F1.

[0072] In this way, after the sampling mechanism 30 is started, if the sampling needle 310 is located at the first station, the sampling needle 310 can be driven by the lifting drive 320 to move downward along the first direction F1 to the sampling station, so that the sampling needle 310 can be inserted into the sample in the sample tube 42 (that is, when the sampling needle 310 is at the sampling station, the sampling needle 310 is inserted into the sample in the sample tube 42), the sampling needle 310 can be used to absorb the sample, and then the sampling needle 310 can be driven by the lifting drive 320 to move upward along the first direction F1, and then the lifting drive 320 and the sampling tube 42 can be driven by the rotating drive 330. The needle 310 rotates around the first preset axis, and then the sampling needle 310 can be rotated to the second position, so that the sampling needle 310 can be located above the titration pool 130, and then the sampling needle 310 is driven by the lifting drive 320 to move downward along the first direction F1 to the injection position, so that the sampling needle 310 can be extended into the titration pool 130 (that is, when the sampling needle 310 is in the injection position, the sampling needle 310 extends into the titration pool 130), and then the sample sucked by the sampling needle 310 is released into the titration pool 130, thereby completing the automatic injection operation of the sample in the sample tube 42.

[0073] After the automatic sampling of the sample is completed, the sampling needle 310 can be cleaned. Specifically, the rotary drive member 330 can drive the lifting drive member 320 and the sampling needle 310 to rotate around the first preset axis, so that the sampling needle 310 can be rotated from the second station to the third station, and then the lifting drive member 320 can drive the sampling needle 310 to move downward along the first direction F1 to the cleaning station, so that the sampling needle 310 can be extended into the cleaning mechanism 60 (that is, when the sampling needle 310 is in the cleaning station, the sampling needle 310 is extended into the cleaning mechanism 60), so as to use the cleaning mechanism 60 to clean the sampling needle 310, so as to better use the sampling needle 310 for the next automatic sampling of the sample.

[0074] In some embodiments, Figure 4 As shown, the cleaning mechanism 60 has a cleaning groove 611 for cleaning the sampling needle 310, and an overflow groove 621 arranged around the cleaning groove 611, and a first cleaning pipe 630 and a liquid outlet pipe 640 respectively connected to the cleaning groove 611 are provided on the side wall of the cleaning groove 611, and an overflow pipe 650 connected to the overflow groove 621 is provided on the overflow groove 621.

[0075] Specifically, the cleaning mechanism 60 includes a first surrounding wall 610 and a second surrounding wall 620 disposed around the first surrounding wall 610 . The first surrounding wall 610 defines a cleaning groove 611 , and the second surrounding wall 620 defines an overflow groove 621 .

[0076] When the sampling needle 310 is in the cleaning position, the sampling needle 310 extends into the cleaning tank 611 .

[0077] When the sampling needle 310 needs to be cleaned, the sampling needle 310 can be driven by the injection mechanism 30 to extend into the cleaning groove 611, and the sampling needle 310 can be cleaned using the cleaning liquid in the first cleaning tube 630. The cleaned liquid can be discharged through the liquid outlet tube 640. Since the overflow groove 621 is arranged around the cleaning groove 611, part of the cleaned liquid can flow into the overflow groove 621 and be discharged through the overflow tube 650, which can effectively prevent the cleaning liquid from overflowing the cleaning mechanism 60 and contaminating or damaging other components of the injection device.

[0078] In some embodiments, along the first direction F1, the portion of the cleaning tank 611 connected to the first cleaning pipe 630 is higher than the portion of the cleaning tank 611 connected to the liquid outlet pipe 640, and the cleaning mechanism 60 also includes a cleaning pump 660, which is connected to the end of the liquid outlet pipe 640 away from the cleaning tank 611. In this way, the cleaning pump 660 can be used to pump the cleaning liquid in the first cleaning pipe 630 into the cleaning tank 611, and the liquid after cleaning can be automatically discharged from the liquid outlet pipe 640 located at the bottom side of the first cleaning pipe 630.

[0079] See also Figure 5The injection mechanism 30 also includes an injection valve 340 and an injection pump 350. The injection valve 340 has a first port 341 connected to the sampling needle 310, and a second port 342 connected to the injection pump 350. The injection valve 340 has a first connection state. When the injection valve 340 is in the first connection state, the first port 341 of the injection valve 340 is connected to the second port 342.

[0080] When the sampling needle 310 extends into the sample tube 42, that is, when the sampling needle 310 is located at the sampling station, the sampling needle 310 can absorb the sample from the sample tube 42 through the injection pump 350. When the sampling needle 310 extends into the titration cell 130, that is, when the sampling needle 310 is located at the injection station, the injection pump 350 can be used to pump the sample absorbed by the sampling needle 310 into the titration cell 130.

[0081] In some embodiments, the injection pump 350 is a syringe pump, see Figure 6 The injection pump includes a stepper motor 351, a second screw rod 352 and a syringe 353. The output end of the stepper motor 351 is connected to the piston of the syringe 353 through the second screw rod 352. The stepper motor 351 drives the second screw rod 352 to rotate, and the rotational motion of the output end of the stepper motor 351 can be converted into a linear motion of the second screw rod 352, thereby pushing the piston of the syringe 353 to perform automatic injection operation, thereby realizing high-precision, smooth and pulsation-free liquid transmission and realizing quantitative injection of samples.

[0082] The injection device also includes a second cleaning pipe 70, and the injection valve 340 also has a third port 343 connected to the second cleaning pipe 70. The injection valve 340 also has a second connection state. When the injection valve 340 is in the second connection state, the second port 342 of the injection valve 340 is connected to the third port 343.

[0083] When the sampling needle 310 needs to be cleaned, the injection valve 340 can be placed in the second connected state first. At this time, the second port 342 of the injection valve 340 is connected to the third port 343, so that the injection pump 350 can absorb the cleaning liquid from the second cleaning pipe 70. Then, the injection valve 340 is placed in the first connected state. At this time, the first port 341 is connected to the second port 342, so that the injection pump 350 can be connected to the sampling needle 310, and then the cleaning liquid absorbed by the injection pump 350 can be pumped into the sampling needle 310, so that the inner wall 312 of the sampling needle 310 can be well cleaned, and the cleaned liquid can be discharged through the above-mentioned liquid outlet pipe 640 and overflow pipe 650.

[0084] Specifically, when the sampling needle 310 extends into the sample tube 42, that is, when the sampling needle 310 is located at the sampling station, the injection valve 340 can be placed in the second connection state, and a section of cleaning liquid will be sucked into the injection pump 350, and then the injection valve 340 is placed in the first connection state, and a section of air, a section of sample (part of the sample in the sample tube 42) and a section of air will be sucked into the injection pump 350, so that a four-section distribution (cleaning liquid-air-sample-air) is formed in the injection pump 350. When the sampling needle 310 extends into the titration cell 130, that is, when the sampling needle 310 is located at the sampling station, the injection pump 350 is used to pump the sample sucked by the sampling needle 310 into the titration cell 130. Then, the sampling needle 310 is cleaned. The rotary drive member 330 can drive the lifting drive member 320 and the sampling needle 310 to rotate around the first preset axis, so that the sampling needle 310 can be rotated from the second station to the third station, and then the lifting drive member 320 can drive the sampling needle 310 to move downward along the first direction F1 to the cleaning station, so that the sampling needle 310 can be extended into the cleaning mechanism 60, and the cleaning pump 660 can be used to pump the cleaning liquid in the first cleaning pipe 630 into the cleaning tank 611 to clean the outer wall 311 of the sampling needle 310, and the cleaning liquid sucked by the injection pump 350 can be pumped into the sampling needle 310. After the cleaning liquid sucked by the injection pump 350 is discharged, the injection valve 340 is placed in the second connected state, and the injection pump 350 can pump the cleaning liquid from the second cleaning pipe 70 into the sampling needle 310, so that the inner wall 312 of the sampling needle 310 can be well cleaned.

The controller 50 includes a first storage module 510 electrically connected to the label identifier 80, and a second storage module 520 electrically connected to the visual recognition device 20. The first storage module 510 is used to store the label information of the sample tube 42, the visual recognition device 20 is used to obtain the analysis results of the sample in the sample tube 42, and the second storage module 520 is used to store the analysis results of the sample in the sample tube 42.

The second acquisition module 2102 is electrically connected to the second storage module 520.

[0091] In this embodiment, the visual recognition device 20 further includes a control module 530, which is electrically connected to the first acquisition module 2101 and the sample injection mechanism 30, respectively. Specifically, the control module 530 is electrically connected to the lifting drive member 320 and the rotating drive member 330 of the sample injection mechanism 30. The control module 530 is used to control the output of the lifting drive member 320 and the rotating drive member 330 according to the sample injection prompt information obtained by the control module 530.

[0092] In this embodiment, the controller 50 also includes a data upload module 540, which is electrically connected to the first storage module 510, the second storage module 520 and the control module 530 respectively.

[0093] In this way, after the label identifier 80 obtains the label information of the sample tube 42, the first storage module 510 of the controller 50 stores the label information of the sample tube 42, and then the first acquisition module 2101 of the visual recognition device 20 and the injection mechanism 30 are used to realize automatic injection of the sample of the sample tube 42, and the second acquisition module 2102 is used to obtain the analysis result of the sample displayed on the display screen 120, and the data upload module 540 can be used to upload the label information of the sample tube 42 and the analysis result of the sample in the sample tube 42 to the database corresponding to the controller 50, so as to obtain the label information of the sample tube 42 and the analysis result of the sample in the sample tube 42 through the database, and the corresponding collection of information such as the source of the sample and the analysis result can be realized, so as to clearly understand the analysis result of the sample of the corresponding source.

[0094] In some embodiments, see Figure 1 , and refer to Figure 7 The sample holder 41 is provided with a plurality of sample tubes 42 spaced apart around a second preset axis. The sampling device further comprises a rotating mechanism 43 connected to the sample holder 41 to drive the sample holder 41 and all the sample tubes 42 to rotate around the second preset axis.

[0095] Taking "the sampling needle 310 has a sampling position, and when the sampling needle 310 is at the sampling position, the sampling needle 310 extends into the sample tube 42 at station a No. 1" as an example, the sample tube 42 at station a No. 2 or station n (n is a positive integer except 1) can be driven to rotate to station a No. 1 by the rotating mechanism 43, and then the injection device can be used to realize automatic injection of samples in multiple sample tubes 42 respectively.

[0096] Illustratively, n is 20, 30 or 40.

[0097] Optionally, the rotating mechanism 43 includes a second rotating motor 431, a second driving wheel 432, a second driven wheel 433 and a second belt 434. The second driving wheel 432 is arranged on the output end of the second rotating motor 431. The second driving wheel 432 is connected to the second driven wheel 433 through the second belt 434. The second driven wheel 433 is arranged around the second rotation axis and is coaxially arranged with the bottom of the sample holder 41. Multiple sample tubes 42 are respectively fixed on the top of the sample holder 41 and are arranged at equal intervals around the second rotation axis.

[0098] In this way, the second rotating motor 431 can drive the sample holder 41 and the multiple sample tubes 42 to rotate around the second rotating axis, so that any sample tube 42 can be rotated to the No. 1 station a, so as to realize automatic injection of samples in the multiple sample tubes 42 respectively.

[0099] See also Figure 8 The sample introduction device also includes a base 91, which has a receiving cavity 911. The rotating mechanism 43 is arranged in the receiving cavity 911, and the output end of the second rotating motor 431 of the rotating mechanism 43 is connected to the sample holder 41. The base 91 is provided with a channel for at least partially accommodating and penetrating along the first direction. The channel is communicated with the receiving cavity 911 so that the output end of the second rotating motor 431 of the rotating mechanism 43 is connected to the sample holder 41.

[0100] The rotating mechanism 43 further includes a third mounting seat 435 disposed in the base 91 , and the second rotating motor 431 is disposed on the third mounting seat 435 .

[0101] The sample injection mechanism 30, the cleaning mechanism 60 and the label identifier 80 are arranged on the top side of the base 91, which can improve the integrity of the sample injection device.

[0102] The sampling device also includes a power supply 92 arranged in the accommodating cavity 911, and a power switch arranged on the outside of the base 91. The power supply 92 is electrically connected to the sampling mechanism 30, the controller 50, the cleaning mechanism 60 and the label identifier 80 through the power switch to provide power to the sampling mechanism 30, the controller 50, the cleaning mechanism 60 and the label identifier 80 and other components that require power.

[0103] The sample injection device also includes a power indicator light 93 connected in series with the power supply 92 and the power switch. During the process of the power supply providing power to the sample injection mechanism 30, the controller 50, the cleaning mechanism 60 and the label identifier 80 and other components requiring power, the power indicator light 93 is in a lighted state.

[0104] The sampling device also includes an emergency stop switch 94, which is used to stop the sampling device in an emergency when a fault or collision occurs during operation, so as to protect the device motor or personal safety.

[0105] The sample injection device also includes a cooling fan 95 disposed in the receiving chamber 911, which can be used to dissipate heat from electrical components such as the power supply 92 and the second rotating motor 431 in the receiving chamber 911, which is beneficial to improving the life and reliability of the sample injection device.

[0106] In some embodiments, see Figure 9-11 The display screen 120 is disposed on the shell 110, and the visual recognition device 20 includes a mounting frame 210 and a camera 220. The mounting frame 210 is disposed on the shell 110, and the camera 220 is disposed on the mounting frame 210, and the camera 220 is set toward the display screen 120 to obtain the picture information displayed on the display screen 120.

[0107] The screen information displayed on the display screen 120 may include sample injection prompt information, sample process data information, and sample analysis results.

[0108] When the display screen 120 displays the sampling prompt information of the sample to be tested, it indicates that the sample to be tested needs to be added into the titration cell 130 at this time. The camera 220 can be used to obtain the picture information displayed on the display screen 120, that is, the camera 220 can be used to obtain the sampling prompt information of the sample to be tested, and then the sampling mechanism 30 is triggered to be in the starting state, and then the sampling mechanism 30 can be used to add the sample to be tested into the titration cell, and then automatic sampling of the sample to be tested can be realized, which solves the problem that the automatic sampling action instruction cannot be triggered, reduces the on-duty personnel set up for sampling, saves manpower, and can also improve the automation level of the analyzer system.

[0109] In some embodiments, the camera 220 is spaced apart from the display screen 120 along the second direction F2, and the camera 220 is configured to be rotatable relative to the mounting bracket 210 around an axis parallel to the third direction F3, and the first direction F1, the second direction F2 and the third direction F3 intersect each other.

[0110] Optionally, the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. For example, the first direction F1 is parallel to the thickness direction of the shell 110, such as the up and down direction; the second direction F2 is parallel to the length direction of the shell 110, such as the front and back direction; the third direction F3 is parallel to the width direction of the shell 110, such as the left and right direction.

[0111] In this way, the angle of the camera 220 relative to the surface of the display screen 120 can be adjusted, so that the angle at which the camera 220 photographs the display screen 120 can be conveniently adjusted to better obtain image information of the display screen 120 .

[0112] In some embodiments, the mounting frame 210 includes two side frames 211 respectively arranged on opposite sides of the shell 110 along the third direction F3, and the visual recognition device 20 also includes a camera mounting seat 230 and at least two connecting seats 240, the connecting seats 240 are correspondingly arranged on the side frames 211, the camera 220 is arranged on the camera mounting seat 230, and the two ends of the camera mounting seat 230 along the third direction F3 are respectively detachably connected to two of the connecting seats 240.

[0113] There may be two connection seats 240, which are arranged on the side frames 211 in a one-to-one correspondence, or three connection seats 240, in which one side frame 211 is provided with one connection seat 240, and the other side frame 211 is provided with two connection seats 240 arranged in sequence along the third direction F3. No specific limitation is made here.

[0114] The connection between the camera mounting bracket 230 and the connecting bracket 240 can be removed, and the camera mounting bracket 230 can be rotated relative to the side frame 211 around an axis parallel to the third direction F3, so that the angle at which the camera 220 shoots the display screen 120 can be well adjusted; after adjusting the angle at which the camera 220 shoots the display screen 120, the two ends of the camera mounting bracket 230 along the third direction F3 are respectively connected to two of the connecting brackets 240, and the camera 220 is fixed at a suitable shooting angle to better obtain the image information of the display screen 120.

[0115] In some embodiments of the visual recognition device, a first connecting hole is provided on the connecting seat 240, and second connecting holes corresponding to the first connecting hole are respectively provided on opposite sides of the camera mounting seat 230 along the third direction F3, and the camera mounting seat 230 is detachably connected to the corresponding connecting seat 240 by means of the second connecting hole and the corresponding first connecting hole.

[0116] Optionally, both the first connection hole and the second connection hole are extended along the third direction F3.

[0117] For example, the first connection hole and the second connection hole are both configured as threaded holes, so that the camera mounting seat 230 can be connected to the corresponding connection seat 240 by bolts matched with the threaded holes, and the two ends of the camera mounting seat 230 along the third direction F3 can be respectively connected to two of the connection seats 240. Of course, the present application is not limited thereto, and the first connection hole and the second connection hole can also be jacks, so that the camera mounting seat 230 can be connected to the corresponding connection seat 240 by bolts matched with the jacks, and the two ends of the camera mounting seat 230 along the third direction F3 can also be respectively connected to two of the connection seats 240.

[0118] In some embodiments, the camera 220 is detachably mounted on the camera mounting base 230 .

[0119] The camera 220 may be directly disposed on the camera mounting seat 230 , or the camera 220 may be indirectly disposed on the camera mounting seat 230 , which is not specifically limited herein.

[0120] The camera 220 can be detachably mounted on the camera mounting seat 230 by means of threaded connection or snap connection, so as to facilitate disassembly or replacement of the camera 220 .

[0121] For example, the camera 220 is detachably mounted on the camera mounting base 230 via a fixing block 250 .

[0122] The fixing block 250 is configured to be movable relative to the camera mounting base 230 along the third direction F3. The fixing block 250 is connected to the camera 220 via a first bolt (not shown), and the fixing block 250 is connected to the camera mounting base 230 via a second bolt (not shown). Figure 5 , the first threaded hole on the fixing block 250 is adapted to the second bolt, see Figure 6 The camera mounting seat 230 is provided with a first oblong hole extending along the third direction F3, and the second bolt is penetrated through the first threaded hole and the first oblong hole and locked by a corresponding nut, so as to realize the connection between the fixing block 250 and the camera mounting seat 230. The position of the fixing block 250 on the first oblong hole along the third direction F3 can be adjusted as needed, thereby adjusting the position of the fixing block 250 relative to the camera mounting seat 230 along the third direction F3, and thereby adjusting the position of the camera 220 relative to the display screen 120 along the third direction F3, so that the camera 220 can better obtain the picture information of the display screen 120.

[0123] In some embodiments, the visual recognition device 20 also includes two damping shafts 270 corresponding one to one with the side frame 211, and the damping shaft 270 is arranged between the side of the corresponding side frame 211 close to the display screen 120 along the second direction F2 and the corresponding connecting seat 240, so that the camera mounting seat 230 is rotatably arranged on the side frame 211 around an axis parallel to the third direction F3 through the damping shaft 270.

[0124] In this way, the whole composed of the camera 220, the camera mounting seat 230, the connecting seat 240 and other components can be rotated around the side of the side frame 211 close to the display screen 120 and around the axis parallel to the third direction F3, and most of the structure of the visual recognition device 20 can be flipped around the axis parallel to the third direction F3 to the top of the display screen 120, so as to free up space for setting up components such as the camera 220 when the visual recognition device 20 is not needed for sample injection operations, and to facilitate the cleaning of the titration cell 130 on the shell 110.

[0125] In some embodiments, the visual recognition device 20 further includes a light shielding hood 280 , and the housing 110 and the light shielding hood 280 define a light shielding space for accommodating the display screen 120 and the camera 220 .

[0126] The light-shielding space can be used to form a darkroom environment for the display screen 120 and the camera 220 , which is more conducive to improving the accuracy of visual recognition performed by the camera 220 .

[0127] In some embodiments, the shell 110 has a carrying portion 111 for partially carrying the shading hood 280, and a side wall portion 112 connected to the top side of the carrying portion 111, and the display screen 120 is disposed on the side wall portion 112, and the carrying portion 111, the side wall portion 112 and the shading hood 280 enclose a shading space.

[0128] In this way, the supporting portion 111 can be used to support the shading cover 280 to improve the installation stability of the shading cover 280. At the same time, the shading space can also be used to form a darkroom environment for the display screen 120 and the camera 220, which is more conducive to improving the accuracy of visual recognition by the camera 220.

[0129] It should be noted that the titration cell 130 is located outside the light-shielding space, which does not affect the use of the titration cell 130 and facilitates regular cleaning of the titration cell 130 .

[0130] In some embodiments, a side of the light shielding cover 280 facing the side wall portion 112 is provided with a avoiding opening 281 communicating with the light shielding space, and the avoiding opening 281 is located above the housing 110 .

[0131] The avoidance opening 281 of the light shield 280 can be utilized to improve the convenience of the overall rotation of the camera 220, the camera mounting socket 230, the connecting socket 240 and other components around the side of the side frame 211 close to the display screen 120 and around the axis parallel to the third direction F3, so as to prevent most of the structure of the visual recognition device 20 from colliding with the light shield 280 during the flipping process around the axis parallel to the third direction F3. It should be noted that the avoidance opening 281 is relatively small and will not cause inaccurate interpretation due to serious light leakage in a dark room environment.

[0132] In some embodiments, a line opening 282 communicating with the light shielding space is defined on a side of the light shielding cover 280 away from the side wall portion 112 along the second direction F2.

[0133] In this way, the power cord of the camera 220 can be passed through the wire opening 282, which facilitates the power on and use of the camera 220, and does not require the light shielding cover 280 to be opened, thereby reducing the impact on the interpretation of the visual recognition device 20. In addition, the operator also observes the information displayed on the display screen 120 through the wire opening 282.

[0134] In some embodiments, the visual recognition device 20 also includes a first connecting frame 291, which is connected between the camera 220 and the mounting frame 210 along the third direction F3, and the light shield 280 is snap-connected to the first connecting frame 291 on one side facing the side wall portion 112.

[0136] Specifically, a slot 283 is defined on one side of the light shield 280 facing the side wall portion 112 , and a portion of the first connecting frame 291 is engaged in the slot 283 .

[0137] The first connecting frame 291 can be used to improve the installation stability of the light shield 280, which is conducive to more stably using the light shield 280 to improve the accuracy of visual recognition by the camera 220. Optionally, the visual recognition device 20 also includes a first connecting plate 293 and a second connecting plate 294, the first connecting plate 293 is connected between the first connecting frame 291 and one of the connecting seats 240, and the second connecting plate 294 is connected between the second connecting frame 292 and the other connecting seat 240.

[0138] Optionally, the connection seat 240 is configured to be movable along the second direction F2 relative to the corresponding side frame 211. Specifically, one connection seat 240 is configured to be movable along the second direction F2 relative to the first connection plate 293, and the other connection seat 240 is configured to be movable along the second direction F2 relative to the second connection plate 294.

[0139] Optionally, the visual recognition device 20 also includes a first support rod 261 and a second support rod 262 respectively arranged on the two side frames 211, the first connecting frame 291 is provided with a first limiting groove adapted to the first support rod 261 and with the groove facing downward, and the second connecting frame 292 is provided with a second limiting groove adapted to the second support rod 262 and with the groove facing downward.

[0140] Specifically, the first support rod 261 passes through the notch of the first limiting groove and extends into the first limiting groove, and the groove side wall of the first limiting groove is provided with two first through holes arranged opposite to each other along the second direction F2, and the first support rod 261 passes through the two first through holes in sequence along the second direction F2.

[0142] In this way, the first support rod 261 and the first limiting groove adapted thereto can be used to improve the stability of the first connecting frame 291 and play a role in supporting the first connecting frame 291. The second support rod 262 and the second limiting groove adapted thereto can also be used to improve the stability of the second connecting frame 292 and play a role in supporting the second connecting frame 292, thereby improving the installation stability of the camera 220.
