Description

Technical Field

[0001] The present invention relates to the technical field of food detection, and in particular to an intelligent food safety detection device and a detection method thereof. Background Art

[0002] The primary purpose of food safety testing is to ensure that food does not contain harmful substances, such as bacteria, viruses, toxins, heavy metals, pesticide residues, etc., which may cause serious harm to human health. Through strict testing, these problematic foods can be discovered and dealt with in a timely manner, thus avoiding diseases and health problems caused by consumers eating unsafe foods.

[0003] A food safety detection device disclosed in a patent application with reference publication (announcement) number CN219675972U controls the drive motor by manually pressing a three-speed switch. Pressing the three-speed switch to one side connects the drive motor to the positive and negative poles of the power supply, so that the output shaft of the drive motor rotates in one direction and drives the worm to rotate, and drives the worm wheel to rotate in one direction, thereby driving the control panel to rotate and form an angle with the upper surface of the food detection device body and face the operator.

[0004] A comprehensive analysis of the above patents reveals the following defects:

[0005] In the above patent application, after the test is completed, the food testing liquid still remains in the test tank and needs to be cleaned manually by the staff. However, the space of the test tank is relatively small, resulting in limited operating space for tools and hands during cleaning, and rapid cleaning cannot be performed. Secondly, when cleaning the test tank, multiple steps such as disconnecting the power supply, disassembling some devices, cleaning, wiping, etc. are required, and the self-cleaning operation of the detection device cannot be achieved. This not only increases the labor intensity of the staff, but the long-term cleaning operation will also affect the continuous use of the detection device and reduce the detection efficiency.

[0006] Therefore, the present invention proposes an intelligent food safety detection device and a detection method thereof which can automatically clean after food safety detection without manual intervention, so as to solve the above-mentioned defects. Summary of the invention

[0063] The embodiment of the present invention also provides a detection method of an intelligent food safety detection device, the method comprising the following steps:

[0064] Step 1. First, weigh the food to be tested quantitatively, crush it and put it into a beaker, and inject an appropriate amount of test liquid according to the amount of the crushed food sample to be tested, and use a glass rod to mix the food powder sample and the test liquid evenly; the test liquid is also called a reagent or indicator, which is commonly used to detect, analyze or measure the chemical substances of specific ingredients or pollutants in food. The test liquid can undergo specific chemical reactions with the target ingredients in the food to produce color changes, precipitation, gas or other observable phenomena, thereby helping the tester to judge the quality, safety or compliance of the food; according to the different test objects, you can choose which test liquid to use or whether to use the test liquid.

[0065] Step 2: Take two portions of the same amount of the mixture of the food powder sample to be tested and the test liquid and place them at different test positions in the test mechanism 5, and then close the drying mechanism 8; the specific process is: in order to illustrate the credibility of the food test result, two portions of the same amount of the food to be tested are tested at the same time; during the test, take out two test object storage tubes 54 respectively, and the taking out process is: since the initial state of the multiple test object storage tubes 54 is that they are all clamped by the annular airbag 535, the screw 58 is rotated counterclockwise, and since the screw 58 The screw rod 58 is threadedly connected to the protective plate and is rotationally connected to the piston 57. Therefore, rotating the screw rod 58 counterclockwise will pull the piston 57 upward. As the piston 57 moves upward, the air inside the annular airbag 535 is gradually drawn into the air chamber 55 through the air inlet pipe 536 and the air supply hose 56. After the annular airbag 535 loses air, its volume gradually decreases, and the binding effect on the detection object storage tube 54 is lost. At this time, the required number of detection object storage tubes 54 are pulled out upward, and equal amounts of gas are injected into the two detection object storage tubes 54 respectively. The mixture of the food powder sample to be tested and the test liquid is then placed in the locking assembly 53 at the corresponding position. When placing, the bottom end of the test object storage tube 54 is inserted from the top of the annular frame 2 534. The test object storage tube 54 passes through the annular frame 2 534 and the annular frame 1 533 in sequence and then reaches the top of the support plate 539 until it abuts against the top of the support plate 539. At this time, the screw 58 is rotated clockwise to push the piston 57 down along the inner wall of the air chamber 55. The air inside the air chamber 55 passes through the air supply hose 56 and the air intake hose 56. The tube 536 enters into the two annular airbags 535. As the amount of air in the annular airbags 535 increases, the volume of the annular airbags 535 gradually increases, and the detection object storage tube 54 is "bound" inside the annular airbags 535. The friction between the detection object storage tube 54 and the annular airbags 535 can ensure that the detection object storage tube 54 will not be separated when the locking assembly 53 is inverted as a whole. At this time, the top of the detection object storage tube 54 and the top of the through slot 52 are on the same horizontal plane, and the detection head at the bottom of the detection probe 6 is slightly higher than the top of the turntable 51.

[0066] Step 3: Click the control button on the touch screen 3 to control the detection mechanism 5 to start the detection. The detection mechanism 5 rotates at a low speed and intermittently in the installation slot 4. The position loaded with the mixture of the food powder sample to be detected and the detection liquid passes through the detection probe 6 in turn. The detection probe 6 detects the food powder sample in the detection mechanism 5, and the detection result is displayed on the touch screen 3. The specific process is as follows: It should be noted that the initial positions of the multiple locking components 53 are not directly below the detection probe 6 and the driving plate 7. A locking mechanism is provided on the output shaft of the micro servo motor 595. When the micro servo motor 595 is running, the locking of the output shaft of the micro servo motor 595 can be automatically released. When the micro servo motor 595 stops running, the locking mechanism can immediately complete the locking of the output shaft of the micro servo motor 595 to prevent the turntable 51 from accidentally rotating and causing the position of the multiple detection object storage tubes 54 to shift. The friction force of the rotary damper 5312 on the transmission shaft 5311 can ensure that the transmission shaft 5311 will not rotate when the support plate 539 is subjected to the force of the driving plate 7 or the top block 5911.

[0067] At this time, click the control button on the touch screen 3 to start the micro servo motor 595. Since the micro servo motor 595 has been programmed, the micro servo motor 595 drives the turntable 51 to rotate in a low-speed, intermittent, and clockwise direction;

[0068] The micro servo motor 595 drives the turntable 51 at the initial position to rotate. When one of the detection object storage tubes 54 rotates to meet the top block 5911, the top opening of the detection object storage tube 54 is just located directly below the detection probe 6. The top block 5911 pushes the support plate 539 to move up quickly. Since the lifting plate 538 and the annular frame 2 534 are connected by the top rod 5310, the annular frame 2 534 is moved up while the support plate 539 moves up. That is, the annular airbag 535, the air inlet pipe 536, the lifting plate 538, the support plate 539, the top rod 5310 and the detection object storage tube 54 inside it move up as a whole. The spring 537 is compressed, and the detection end at the bottom of the detection probe 6 is inserted into the detection object storage tube 54 as it moves up. At this time, the micro servo motor 595 enters a ten-second interval, and the detection probe 6 transmits the detected data to the touch screen 3 for display.

[0069] Step 4: After the detection operation is completed, the part of the detection mechanism 5 loaded with the detection food powder sample and the detection liquid mixture continues to rotate and change position, and after meeting the flushing component, the detection mechanism 5 is flushed under the drive of the driving plate 7; the specific process is: after the interval time ends, the micro servo motor 595 continues to drive the turntable 51 to rotate clockwise, and after the bottom end of the support plate 539 is separated from the top end of the top block 5911, the elastic force of the spring 537 pushes the annular frame 534 to move down quickly to the original position. During this period, since the detection probe 6 is located in the middle position of the opening of the detection object storage tube 54 during the detection period, at the moment when the support plate 539 and the top block 5911 are separated, the detection end of the detection probe 6 will not interfere with the detection object storage tube 54;

[0070] When the turntable 51 continues to rotate, the gear 5313 and the arc-shaped rack 593 meet and mesh. During the meshing period, the arc-shaped rack 593 drives the gear 5313 to overcome the resistance of the rotary damper 5312 and rotate 180 degrees. Since the air inlet pipe 536, the turntable 51 and the air supply hose 56 are all sealed and rotatably connected, the rotation of the gear 5313 drives the locking assembly 53 to rotate 180 degrees as a whole, that is, the detection object storage tube 54 is in an inverted state. During this process, the detection food located in the detection object storage tube 54 is dumped into the wastewater collection box 10. Then, the inverted locking assembly 53 continues to rotate to the bottom of the driving plate 7. The bottom of the driving plate 7 pushes the support plate 539 to move downward instantly, and the bottom end opening of the detection object storage tube 54 is completely pressed on the sealing rubber sleeve 597. At the top of the detection object storage tube 54, the sealing rubber sleeve 597 and the arc-shaped slideway 596 form a closed space inside the detection object storage tube 54. At this time, the nozzle 598 and the liquid discharge port 599 are covered in the detection object storage tube 54. The micro servo motor 595 enters a ten-second interval again. At the moment when the detection object storage tube 54 is pressed on the top of the sealing rubber sleeve 597, the touch switch 5910 located inside the sealing rubber sleeve 597 is triggered at the same time. The water pump 11 enters a working state under the control of the touch switch 5910. The water pump 11 extracts clean water from the clean water tank 12 and inputs it into the nozzle 598 through a pipeline. The water flow impacts the inner wall of the detection object storage tube 54 at a high speed. The food waste remaining on the inner wall of the detection object storage tube 54 enters the liquid discharge port 599 with the water flow and falls into the wastewater collection tank 10 for storage under the action of gravity.

[0071] Step 5: Click the start control button for controlling the drying mechanism 8 on the touch screen 3, and the drying mechanism 8 blows hot air to the detection mechanism 5 to dry the rinsed position; the specific process is: after the rinsing is completed, the turntable 51 continues to rotate, and the moment the support plate 539 and the bottom of the driving plate 7 are separated, the spring 537 pushes the whole composed of the annular frame 534, the annular airbag 535, the air inlet pipe 536, the lifting plate 538, the support plate 539, and the push rod 5310 to move up quickly. During this period, the nozzle 598 will not The detection object storage tube 54 interferes, and the water pump 11 is immediately controlled to be turned off after the pressure on the top of the touch switch 5910 is lost; when the turntable 51 continues to rotate, the gear 5313 and the arc rack 2 594 are meshed, and the arc rack 2 594 drives the gear 5313 to continue to rotate 180 degrees, and the detection object storage tube 54 returns to the original state from the inverted state, until the micro servo motor 595 drives the turntable 51 to rotate one circle and returns to the original state again, and then the micro servo motor 595 is turned off, and the detection of the food sample is ended;

[0072] Next, the hot air blower 82 is turned on by means of the touch button of the drying mechanism 8 on the touch display screen 3. The hot air generated by the hot air blower 82 is blown onto the multiple detection object storage tubes 54 through the multiple air outlets 83. The water stains remaining on the inner walls of the detection object storage tubes 54 are evaporated by the heat, and the detection object storage tubes 54 are dried.
