The operation steps are cumbersome and time-consuming. Moreover, the transfer process may be affected by external contamination or temperature fluctuations, which reduces the accuracy and timeliness of the test results. This needs to be improved. Therefore, a visual milk milk quality sampling and testing equipment is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A visual milk quality sampling and testing device includes a sampling tube 1, a piston ring 2 slidably disposed inside the sampling tube 1, a sealing disk 3 fixedly mounted on the top surface of the piston ring 2, a display 4 fixedly mounted on the top surface of the sealing disk 3, a detection probe 5 fixedly mounted on the bottom surface of the sealing disk 3, the detection probe 5 being electrically connected to the display 4 and located in the middle of the piston ring 2, a vertical rod 6 fixedly mounted on the top of the display 4, a circular plate 7 fixedly mounted on the top of the vertical rod 6, a valve 8 disposed at the bottom end of the sampling tube 1, an electric push rod 9 fixedly mounted on the side of the sampling tube 1, and the circular plate 7 disposed at the end of the output shaft of the electric push rod 9.

[0033] When sampling and testing milk, the operator inserts the sampling tube 1 into the milk and activates the electric push rod 9 on the side of the sampling tube 1. The output shaft of the electric push rod 9 pushes the circular plate 7 to move vertically upward. The circular plate 7 drives the display 4, the sealing plate 3, and the piston ring 2 to slide upward inside the sampling tube 1 through the vertical rod 6. As the piston ring 2 moves upward, a negative pressure is formed inside the sampling tube 1. Under the action of the external atmospheric pressure, the milk pushes open the valve 8 at the bottom of the sampling tube 1 and is drawn into the sampling tube 1. After the sample is extracted, the entire device is taken out. The valve 8 seals the bottom of the sampling tube 1 to prevent milk leakage and contamination.

[0034] After the milk sample is drawn into the sampling tube 1, the entire device is inverted so that the detection probe 5 is immersed in the milk sample, and various quality data of the milk are detected in real time. The detection data is then transmitted to the display 4 for intuitive display.

[0035] By setting up the sampling tube 1, piston ring 2, sealing plate 3, display 4, detection probe 5, vertical rod 6, circular plate 7, valve 8, and electric push rod 9 to work together, this utility model integrates sampling and detection, enabling rapid sampling and detection of milk, effectively improving detection accuracy and efficiency. The device has a simple overall structure, is easy to operate, and is highly practical.

[0036] A plug block 10 is fixedly installed on the side of the circular plate 7, and a connecting block 11 is fixedly installed at the end of the output shaft of the electric push rod 9. The connecting block 11 is directly opposite the plug block 10, and the size of the connecting block 11 is adapted to the size of the plug block 10. The plug block 10 and the connecting block 11 are fixedly installed by a hand-tightening screw 12.

[0037] The insert block 10 fixedly installed on the side of the circular plate 7 and the connecting block 11 at the end of the output shaft of the electric push rod 9 are matched in size and can be quickly and accurately connected. The operator can fix the two by hand-tightening the screw 12 to form an automatic sampling mode in which the electric push rod 9 drives the circular plate 7. If it is necessary to switch to manual sampling mode, the operator can loosen the hand-tightening screw 12, separate the insert block 10 and the connecting block 11, and directly press or lift the circular plate 7 manually. The piston ring 2 is driven up and down by the vertical rod 6 to complete the sampling. This allows the device to flexibly switch between automatic and manual operation to adapt to different scenario requirements.

[0038] Sampling tube 1 is configured as a two-section tube, with the two sections connected by threads;

[0039] The sampling tube 1 is set in two sections, and the two sections are connected by threads. The operator can rotate the two sections of the sampling tube 1 to separate them. The two sections of the sampling tube 1 can be rinsed or soaked for disinfection after separation. After cleaning, the two sections of the sampling tube 1 are realigned with the threads and tightened to restore the integrity of the device.

[0040] A handle 13 is provided on the top side of the sampling tube 1, and the handle 13 is threadedly connected to the sampling tube 1.

[0041] During sampling, the operator can hold the handle 13 to hold the device more stably, making it easier to insert the sampling tube 1 into the milk for sampling. When the handle 13 is no longer needed, the operator can rotate the handle 13 to loosen its threaded connection with the sampling tube 1, thereby removing the handle 13 from the sampling tube 1 for easy storage.

[0042] A gap is provided between the detection probe 5 and the inner wall of the piston ring 2;

[0043] A gap is provided between the detection probe 5 and the inner wall of the piston ring 2, so that the extracted milk sample can completely surround the detection probe 5, which can more accurately detect various quality indicators of milk and improve the accuracy of detection.

[0044] The sampling tube 1 has graduations on its side;

[0045] The sampling tube 1 has a scale on its side, which allows operators to clearly understand the milk sampling volume by observing the scale, thus meeting the sampling volume requirements of different testing needs.

[0046] Working principle:

[0047] When sampling and testing milk, the operator inserts the sampling tube 1 into the milk and activates the electric push rod 9 on the side of the sampling tube 1. The output shaft of the electric push rod 9 pushes the circular plate 7 to move vertically upward. The circular plate 7 drives the display 4, the sealing plate 3, and the piston ring 2 to slide upward inside the sampling tube 1 through the vertical rod 6. As the piston ring 2 moves upward, a negative pressure is formed inside the sampling tube 1. Under the action of the external atmospheric pressure, the milk pushes open the valve 8 at the bottom of the sampling tube 1 and is drawn into the sampling tube 1. After the sample is extracted, the entire device is taken out. The valve 8 seals the bottom of the sampling tube 1 to prevent milk leakage and contamination.

[0048] After the milk sample is drawn into the sampling tube 1, the entire device is inverted so that the detection probe 5 is immersed in the milk sample, and various quality data of the milk are detected in real time. The detection data is then transmitted to the display 4 for intuitive display.

[0049] By setting up the sampling tube 1, piston ring 2, sealing plate 3, display 4, detection probe 5, vertical rod 6, circular plate 7, valve 8, and electric push rod 9 to work together, this utility model integrates sampling and detection, which can quickly sample and detect milk, effectively improve the accuracy and efficiency of detection. The overall structure of the device is simple, easy to operate, and highly practical.

[0050] in,

[0051] The insert block 10 fixedly installed on the side of the circular plate 7 and the connecting block 11 at the end of the output shaft of the electric push rod 9 are matched in size and can be quickly and accurately connected. The operator can fix the two by hand-tightening the screw 12 to form an automatic sampling mode in which the electric push rod 9 drives the circular plate 7. If it is necessary to switch to manual sampling mode, the operator can loosen the hand-tightening screw 12, separate the insert block 10 and the connecting block 11, and directly press or lift the circular plate 7 manually. The piston ring 2 is driven up and down by the vertical rod 6 to complete the sampling. The device can flexibly switch between automatic and manual operation to adapt to different scenario requirements.

[0052] The sampling tube 1 is set in two sections and the two sections are connected by threads. The operator can rotate the two sections of the sampling tube 1 to separate them. The two sections of the sampling tube 1 can be rinsed or soaked for disinfection after separation. After cleaning, the two sections of the sampling tube 1 can be realigned with the threads and tightened to restore the integrity of the device.

[0053] When performing sampling, the operator can hold the handle 13 to hold the entire device more stably, making it easier to insert the sampling tube 1 into the milk for sampling. When the handle 13 is no longer needed, the operator can rotate the handle 13 to loosen its threaded connection with the sampling tube 1, thereby removing the handle 13 from the sampling tube 1 for easy storage.

[0054] A gap is provided between the detection probe 5 and the inner wall of the piston ring 2, so that the extracted milk sample can completely cover the detection probe 5, which can more accurately detect various quality indicators of milk and improve the accuracy of detection.

[0055] The sampling tube 1 has a scale on its side, which allows operators to clearly understand the milk sampling volume by observing the scale, thus meeting the sampling volume requirements of different testing needs.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
