Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine detection technology, specifically relating to a device for rapid detection of aflatoxin in traditional Chinese medicinal materials. Background Technology

[0002] Aflatoxin is a difuran ring toxin produced by certain strains of Aspergillus flavus and Aspergillus parasiticus. It is extremely toxic and carcinogenic, posing a serious threat to the quality and safety of traditional Chinese medicine (TCM) materials. Aflatoxin is a common mycotoxin in TCM materials, with extremely high toxicity. Long-term intake may cause serious harm to health. Therefore, rapid detection of aflatoxin in TCM materials is crucial for ensuring food safety. Based on this, a rapid detection device for aflatoxin in TCM materials was designed. This device can greatly improve the efficiency of TCM safety testing, reduce human factors and time delays in traditional laboratory testing, and ensure the health and safety of consumers.

[0003] However, existing technologies still suffer from low automation and cumbersome operating procedures. Furthermore, current testing relies on laboratory equipment, requiring manual extraction and transfer of samples, which is time-consuming and cannot provide rapid on-site quantification. Utility Model Content

[0004] The purpose of this invention is to provide a device for rapid detection of aflatoxin in Chinese medicinal materials, so as to solve the problems of cumbersome operation and long detection time in the existing technology.

[0007] A detection box, wherein the detection box is disposed inside the outer shell, and a flexible lever is provided at the front end of the detection box;

[0008] A reciprocating mechanism is disposed on one side inside the housing. The reciprocating mechanism includes a slider, which is fixedly connected to the detection box and used to drive the detection box to move horizontally.

[0009] An extraction mechanism is disposed above the moving path of the detection box and includes an extraction bottle and a valve assembly for controlling the opening and closing of the flow tube;

[0011] A spectrometer is located at the end of the movement path of the detection box, with a detection opening on its side and a display screen.

[0012] When the detection box moves to the bottom of the extraction bottle, its lever triggers the flow tube to open, and after receiving the extract, it moves to the spectrometer detection position.

[0013] In a preferred embodiment, the reciprocating mechanism further includes a stepper motor, which is fixedly connected to the outer wall of the housing. A synchronous pulley is fixedly connected to the output end of the stepper motor, and a synchronous belt is provided around the synchronous pulley. Another synchronous pulley is provided at the other end of the synchronous belt, and the two synchronous pulleys rotate synchronously through the synchronous belt.

[0014] In a preferred embodiment, the timing belt is internally connected to a retaining tooth, which is fixedly connected to the slider. A sliding rod is fixedly connected inside the housing, and the slider is slidably connected to the outer wall of the sliding rod.

[0015] In a preferred embodiment, the extraction mechanism includes a support frame disposed within a housing and coaxial with the spectrometer, a flow tube disposed below the extraction bottle, and a valve assembly disposed between the extraction bottle and the lever.

[0016] In a preferred embodiment, in the valve assembly, the lever passes through a sleeve, the sleeve is fixedly connected to the outer wall of the extraction bottle, one end of the lever is provided with a limiting bead, the outer sleeve of the lever is provided with a spring, one end of the spring is fixedly connected to the lever, and the other end abuts against the extraction bottle.

[0019] The technical effects achieved by this utility model are as follows:

[0020] This utility model discloses a rapid detection device for aflatoxin in traditional Chinese medicine. By setting up a reciprocating mechanism, a stepper motor drives a synchronous wheel to rotate. When the synchronous wheel rotates, a synchronous belt drives a slider to move, which in turn moves the detection box.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0035] like Figures 1-3 As shown, a rapid detection device for aflatoxin in traditional Chinese medicine includes a housing 1, and further includes:

[0036] The detection box 3 is installed inside the outer shell 1, and the front end of the detection box 3 is provided with a flexible lever 31;

[0037] A reciprocating mechanism 2 is disposed on one side inside the housing 1. The reciprocating mechanism 2 includes a slider 25, which is fixedly connected to the detection box 3 and is used to drive the detection box 3 to move horizontally.

[0038] Extraction mechanism 4 is located above the moving path of detection box 3 and includes extraction bottle 41 and valve assembly for controlling the opening and closing of flow tube 42;

[0039] The storage bottle 5 is connected to the extraction bottle 41 via the inlet pipe 45, and the storage bottle 5 has a built-in water pump.

[0040] The spectrometer 6 is located at the end of the moving path of the detection box 3, with a detection opening on the side and a display screen 61.

[0041] When the detection box 3 moves to the bottom of the extraction bottle 41, its lever 31 triggers the lever 43 to open the flow tube 42, and after receiving the extract, it moves to the detection position of the spectrometer 6.

[0042] In the above embodiment, when the device is needed, the herb to be tested is first crushed into powder. Then, the operator places filter paper into the extraction bottle 41, followed by the herb powder. The water pump in the storage bottle 5 is then activated, allowing the extractant in the storage bottle 5 to enter the extraction bottle 41 through the inlet pipe 45 and combine with the herb powder to form an extract. The reciprocating mechanism 2 moves the detection box 3. When the detection box 3 is moved to below the extraction bottle 41, the lever 31 at the front of the detection box 3 contacts the lever 43. As the detection box 3 continues to move, the lever 31 pushes the lever 43 to the right, simultaneously compressing the spring 433 to contract it. When the lever 43 moves to the right, the lever 43... The through hole on the 3 connects to the extraction bottle 41 and the flow tube 42, allowing the extract in the extraction bottle 41 to flow through the flow tube 42 to the detection box 3. At this time, the stepper motor 21 is stopped by the external control system. After the extract is discharged, the stepper motor 21 is started again to move the detection box 3 to the right. Since the material of the lever 31 is relatively soft, after the detection box 3 moves to the right position, the lever 31 deforms and slides across the lever 43. At this time, the resistance of the spring 433 disappears, and the lever 43 is reset by the spring 433. After the detection box 3 moves to the right into the upper opening of the spectrometer 6, the stepper motor 21 is stopped. At this time, the spectrometer 6 is started to measure the extract, and the measured result is displayed on the display screen 61.

[0043] It should be further explained that the start-up process of the stepper motor 21 and the spectrometer 6 is set by a fixed program through an external control system to control their opening and closing, so as to ensure that the detection liquid can be detected as soon as the detection box 3 is driven into the spectrometer 6, and can also be shut down in time after the detection is completed. The release time of the stepper motor 21 and the extraction liquid is also controlled by the external control system to control the stop time of the stepper motor 21, so as to ensure that there is enough extraction liquid in the detection box 3.

[0044] like Figure 3 - Figure 4 As shown, the reciprocating mechanism 2 also includes a stepper motor 21, which is fixedly connected to the outer wall of the housing 1. A synchronous pulley 22 is fixedly connected to the output end of the stepper motor 21. A synchronous belt 23 is provided on the outer sleeve of the synchronous pulley 22. Another synchronous pulley 22 is provided at the other end of the synchronous belt 23. The two synchronous pulleys 22 rotate synchronously through the synchronous belt 23. A retaining tooth 24 is engaged inside the synchronous belt 23. The retaining tooth 24 is fixedly connected to the slider 25. A slide rod 26 is fixedly connected inside the housing 1. The slider 25 is slidably connected to the outer wall of the slide rod 26.

[0045] In the above embodiment, two slide bars 26 are provided on the front side of the synchronous belt 23. The slide bars 26 can not only limit the slider 25 to prevent the slider 25 from overturning, but also provide partial load-bearing function for the slider 25 when it slides. This can reduce the weight borne by the synchronous belt 23 and allow the synchronous belt 23 to drive the pre-engaged teeth 24 to move without obstruction.

[0046] Furthermore, the stepper motor 21 is controlled to rotate forward and backward by an external control system, thereby enabling the detection box 3 to move back and forth left and right to perform multiple detections.

[0047] like Figure 5 As shown, the extraction mechanism 4 includes a support 44, which is disposed inside the housing 1 and is on the same axis as the spectrometer 6. A flow tube 42 is disposed below the extraction bottle 41, and a valve assembly is disposed between the extraction bottle 41 and the lever 43.

[0048] In the above embodiment, the top of the extraction bottle 41 is set to be semi-open, which makes it convenient for the staff to add the Chinese medicine powder and filter paper into the extraction bottle 41 at the beginning of the test. The flow tube 42 has an inclined slope, which facilitates the flow of the solution and also plays a guiding role, so that the liquid outlet is closer to the test box 3 and prevents the support 44 from affecting the travel of the test box 3.

[0049] Furthermore, when the valve assembly is opened, a liquid delivery channel is formed between the extraction bottle 41, the valve assembly, and the flow tube 42, allowing the solution in the extraction bottle 41 to flow into the detection box 3.

[0050] like Figure 2 , Figure 6 and Figure 7 As shown, in the valve assembly, the lever 43 passes through the sleeve 432, the sleeve 432 is fixedly connected to the outer wall of the extraction bottle 41, one end of the lever 43 is provided with a limiting bead 431, and the outer sleeve of the lever 43 is provided with a spring 433, one end of the spring 433 is fixedly connected to the lever 43, and the other end abuts against the extraction bottle 41.

[0051] In the above embodiment, a through hole with a diameter equivalent to the lower end of the extraction bottle 41 and the inner diameter of the flow tube 42 is provided at the horizontal section of the lever 43 for solution flow; wherein, the lever 43 is inclined, and the front end of the lever 43, that is, the lowest end, is inclined towards the detection box 3, so that the lever 31 can contact it and open the infusion channel.

[0052] like Figure 7 As shown, the lever 31 of the detection box 3 is made of a deformable flexible material, and can be disengaged from the lever 43 by deformation during reset.

[0053] In the above embodiment, the material of the paddle 31 is deformable and has sufficient hardness to move the lever 43. After the paddle is moved, the reaction force applied by the lever 43 is sufficient to deform the paddle 31, causing the lever 43 to disengage from the paddle 31.

[0054] like Figure 3 As shown, the water pump built into the storage bottle 5 is connected to the inlet pipe 45 and is used to pump the extractant into the extraction bottle 41.

[0055] In the above embodiment, the extractant in the storage bottle 5 is transported into the extraction bottle 41 by a water pump without manual intervention.

[0056] The working principle of this utility model is as follows: When the device is needed, the herbs to be tested are first crushed into powder. Then, the operator places filter paper into the extraction bottle 41, followed by the herbal powder. The water pump in the storage bottle 5 is then activated, drawing the extractant from the storage bottle 5 into the extraction bottle 41 through the inlet pipe 45 to combine with the herbal powder and generate an extract. Then, the stepper motor 21 is activated. When the stepper motor 21 is working, it drives the synchronous pulley 22 to rotate. As the synchronous pulley 22 rotates, the synchronous belt mounted on it... 23 drives another synchronous wheel 22 to rotate, which in turn drives the slider 25 to move horizontally along the axis through the locking teeth 24, thereby moving the detection box 3. During the movement, a sliding rod 26 slides inside the slider 25 to ensure that the slider 25 does not deviate in the horizontal axis direction, while also sharing the weight of the slider 25 and the detection box 3. When the detection box 3 is moved to below the extraction bottle 41, the paddle 31 set in front of the detection box 3 contacts the lever 43. As the detection box 3 continues to move, the paddle 31 pushes the lever 43 to move to the right, while compressing the spring 433 to contract the spring 433. When lever 43 moves to the right, the through hole on lever 43 connects with extraction bottle 41 and flow tube 42, allowing the extract in extraction bottle 41 to flow through flow tube 42 to detection box 3. At this time, the stepper motor 21 is stopped by the external control system to discharge the extract. After the extract is discharged, the stepper motor 21 is restarted to move detection box 3 to the right. Since the material of lever 31 is relatively soft, after detection box 3 moves to the right position, lever 31 deforms and slides across lever 43. At this time, the resistance of spring 433 disappears, and the spring 433 rebounds to restore lever 43 to its original position. The device is positioned to prevent leakage of residual waste in the extraction bottle 41, and a limiting bead 431 is provided at one end of the lever 43 to prevent the lever 43 from slipping during reset. After the detection box 3 moves to the right into the upper opening of the spectrometer 6, the stepper motor 21 is stopped. At this time, the spectrometer 6 is started to measure the extract, and the measured results are displayed on the display screen 61. This device can not only automatically detect, but also directly measure the content of aflatoxin in the medicinal material by using the spectrometer 6 to detect the spectral reaction of aflatoxin. It can achieve rapid real-time detection without complicated sample processing.

[0057] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
