Description

Technical Field

[0001] This invention relates to the field of food detection sensor technology, and more specifically, to a food detection device with multiple sampling functions. Background Technology

[0002] In the fields of food safety supervision and routine quality inspection, it is often necessary to conduct batch testing of the composition and physicochemical indicators of a large number of fluid or semi-fluid food samples. Since different types of food or different testing items for the same food often require specific types of sensor probes, current food testing work largely relies on manual operation. This means that testers must manually change the corresponding testing instruments or sensor probes for different samples one by one. When faced with large-scale, mixed testing of various types of sampling cups, this traditional method is not only inefficient but also highly susceptible to human error leading to mismatches between samples and testing items. Although some testing institutions have introduced multi-axis robotic arms to grasp different probes for automated point-of-care testing, these flexible devices generally suffer from high costs, large size, and complex control logic, making them difficult to widely adopt in small and medium-sized testing laboratories or high-frequency rapid testing scenarios.

[0003] Furthermore, existing multifunctional automated food testing devices suffer from significant deficiencies in their cross-contamination protection and cleaning mechanisms during actual operation. On one hand, after the sensor probe is inserted into highly viscous food liquid for testing, residual liquid and dirt inevitably adhere to its surface. Current conventional automatic rinsing devices cannot effectively remove residual water droplets from the probe surface after cleaning, and prolonged water droplet adhesion can easily lead to corrosion. On the other hand, non-stationary sampling cups are prone to centrifugal tilting or liquid surface sloshing during base transport and the start / stop process of testing. If positioning is off, the delicate sensor that has descended is easily damaged by impact with the cup wall.

[0004] Therefore, the present invention provides a food testing device with multiple sampling functions to solve the above problems. Summary of the Invention

[0005] To overcome the above-mentioned defects, the present invention provides a food testing device with multiple sampling functions, which solves the problems of low detection efficiency caused by the inability of existing food testing equipment to intelligently identify and automatically switch sensors according to samples, and the problem that residual moisture on the probe surface after cleaning can easily lead to corrosion of the detection head.

[0006] According to one aspect, at least one embodiment of the present invention provides a food testing device with multiple sampling functions, comprising: The base has a turntable for placing sampling cups rotatably mounted on its top wall. The base is equipped with a drive mechanism that drives the turntable to rotate intermittently. A touch screen control panel is mounted on the top of the base via a column.

The smart sensor detection component is used to detect fluid food in a sampling cup. A cleaning component is installed at the bottom of the smart sensor detection component, and the cleaning component is used to clean the smart sensor detection component after detection.

[0007] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, the top wall of the turntable is symmetrically provided with placement grooves that match the sampling cups, the inner wall of the placement grooves is symmetrically provided with installation grooves, and a limiting mechanism for clamping the sampling cups is installed in the installation grooves.

The squeezing block is slidably installed in the corresponding mounting groove. The side wall of the squeezing block is fixedly connected to the inner side wall of the mounting groove by the No. 3 spring. The top of the clamping end of the squeezing block is inclined.

[0009] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, the intelligent sensor detection component includes an n-shaped frame and an electric telescopic rod. The n-shaped frame is fixed to the side wall of the base by a mounting bracket. An mounting cylinder is slidably installed inside the n-shaped frame. Guide grooves are provided on both inner walls of the n-shaped frame. Guide blocks are symmetrically fixed on both sides of the top of the outer wall of the mounting cylinder, and several limiting grooves are symmetrically opened on the inner wall of the mounting cylinder. A pressing control mechanism is installed at the center of the mounting cylinder. The guide block is slidably installed in the corresponding guide groove; The electric telescopic rod is fixed in the middle of the top wall of the n-shaped frame, and the movable end of the bottom of the electric telescopic rod slides through the top wall of the n-shaped frame and the top wall of the mounting cylinder and is fixedly connected to the center position of the top wall of the pressing control mechanism. Each of the limiting slide grooves is fixed with a vertically arranged guide shaft, and a limiting slider is slidably installed in the limiting slide groove. The guide shaft slides through the limiting slider, and a No. 1 spring is sleeved on the outside of the guide shaft. The No. 1 spring is fixed between the bottom wall of the limiting slider and the bottom wall of the limiting groove. The sensor body is fixed to the side wall of the limiting slider via a connecting shaft, and an integrated detection head is installed at the bottom of the sensor body.

[0010] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, the pressing control mechanism includes a mounting block, the mounting block is fixed on the bottom movable end of the electric telescopic rod, and a storage groove is provided on the side wall of the mounting block corresponding to the position of the sensor body, and a rotating plate is rotatably installed in the storage groove; The bottom end of the rotating plate is rotatably mounted on the bottom of the storage slot, and a sliding block is rotatably mounted on the inner side of the rotating plate via a connecting plate; The sliding block is slidably installed in the storage slot, and an optical axis slides through the center of the sliding block. A ring-shaped magnetic block is fixed at the top of the sliding block. A second spring is fitted on the outer side of the optical axis, and an electromagnet is installed at the top of the optical axis; The second spring is fixed between the bottom wall of the sliding block and the bottom wall of the storage groove; The electromagnet and the magnetic block share the same magnetic pole at the end that is close to each other.

[0011] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, the bottom of the side wall of the mounting cylinder is provided with thread teeth, and the bottom wall of the mounting cylinder is provided with a through hole corresponding to the position of the detection head.

[0012] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, the cleaning component includes a threaded cap, the threaded cap is matched with the thread teeth at the bottom of the mounting cylinder, a storage groove is provided on the bottom wall of the inner cavity at the top of the threaded cap, and a ring tube is installed at the bottom of the side wall of the threaded cap. The storage tank contains an absorbent sponge, and the bottom wall of the storage tank has several arc-shaped through grooves corresponding to the position of the detection head. The outer wall of the ring tube is fixedly connected to a connecting pipe, and the inner wall of the ring tube is fixedly connected to a plurality of nozzles extending to the inner cavity of the bottom of the threaded cap. The bottom inner cavity of the threaded cap is fixed with an annular baffle that matches the top of the sampling cup, and the top wall of the annular baffle is inclined.

[0013] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, a drive slot and a motor slot are provided inside the base corresponding to the position of the drive mechanism.

[0014] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, the driving mechanism includes an active dial, a driven groove wheel and a drive motor, the active dial is rotatably mounted on the bottom wall of the drive groove, and the active dial is matched with the driven groove wheel; A mounting sleeve is fixed at the center of the top wall of the driven groove wheel. The top of the mounting sleeve passes through the top wall of the drive groove through a bearing and is fixedly connected to the center of the bottom wall of the turntable. The bottom of the column slides through the turntable, the driven groove wheel and the mounting sleeve and is fixed on the bottom wall of the drive groove. The drive motor is fixed inside the motor slot, and the power shaft of the drive motor passes through the top wall of the motor slot via a bearing and is fixedly connected to the bottom wall axis of the active dial.

[0015] For example, in a food testing device with multiple sampling functions provided in at least one embodiment of the present invention, a transparent label insert is installed on the side wall of the sampling cup.

[0016] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, a Geneva mechanism consisting of an active dial and a driven Geneva wheel within the base converts the rotation of the drive motor into intermittent, equal-step rotation of the turntable. Combined with a limiting mechanism within the turntable's placement slot, this mechanism stably limits the placement of the sampling cup, preventing it from shaking during start-up and shutdown, and ensuring that the detection head of the intelligent sensor detection component does not touch or damage the side wall of the sampling cup during inspection. Simultaneously, a camera, in conjunction with a label insert on the side wall of the sampling cup, extracts image features. The system automatically determines the current sample's detection requirements and then individually controls the corresponding electromagnet in the pressing control mechanism to be energized. Utilizing the physical principle of like magnetic poles repulsion, the electromagnet at a specific station repels the magnetic block downwards, pushing the concealed rotating plate in the corresponding storage slot to a horizontal state. Subsequently, in conjunction with the overall downward movement of the electric telescopic rod, a purely mechanical interference structure vertically pushes out and presses the required sensor probe into the corresponding sampling cup, perfectly avoiding complex robotic arm reversal control. The overall structure is simplified and offers excellent protection.

[0017] 2. In this invention, a cleaning component with a ring nozzle, an arc-shaped channel, a water-absorbing sponge, and an annular baffle is installed at the bottom of the intelligent sensor detection component. During the process of the sensor being lifted and reset by the No. 1 spring after a single sampling detection, the probe can be rinsed by the nozzle. During the process of the sensor detection probe continuing to retract upward after being sprayed, the sponge's squeezing friction and capillary water absorption characteristics are used to scrape off and dry the tiny water droplets remaining on the outer surface of the probe, which can effectively prevent the detection head from being corroded by water droplets remaining on the surface of the detection head for a long time.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Example

[0026] refer to Figure 1 , Figure 2 , Figure 8 and Figure 9This embodiment provides a food testing device with multiple sampling functions, including a base 1. A turntable 2 for placing sampling cups 10 is rotatably mounted on the top wall of the base 1. Since the testing of different food samples requires a certain independent dwell time, a drive mechanism is provided inside the base 1 to achieve intermittent rotation and transmission of the turntable 2. A drive groove 13 and a motor groove 14 are provided inside the base 1 corresponding to the position of the drive mechanism. The drive mechanism specifically includes an active dial 16, a driven groove wheel 17, and a drive motor 19. The active dial 16 is rotatably mounted on the bottom wall of the drive groove 13, and the driven groove wheel 17 matches the active dial 16 to form an intermittent transmission mechanism. A mounting sleeve 18 is fixed at the center of the top wall of the driven groove wheel 17. The top of the mounting sleeve 18 passes through the top wall of the drive groove 13 through a bearing and is fixedly connected to the center of the bottom wall of the turntable 2. The drive motor 19 is fixed in the motor groove 14, and its power shaft passes through the top wall of the motor groove 14 through a bearing and is fixedly connected to the center of the bottom wall of the active dial 16. During operation, the drive motor 19 rotates, and the continuous rotational motion is converted into the equally divided intermittent rotation of the turntable 2 through the grooved wheel mechanism, so that the sampling cup 10 can accurately stop at the detection station in front.

[0027] Furthermore, a touchscreen control panel 4 is mounted on top of the base 1 via a column 3. The bottom end of the column 3 slides through the turntable 2, the driven groove wheel 17, and the mounting sleeve 18 and is fixed to the bottom wall of the drive groove 13, providing stable support for the central control unit. At the front end of the base 1, a camera 12 for preliminary information collection is fixed via a mounting plate 11. Correspondingly, a transparent label insert 22 is installed on the side wall of the sampling cup 10 for placing labels with barcodes indicating the food type and testing items.

[0028] To ensure the absolute stability of the sampling cup 10 during rotation and testing, the top wall of the turntable 2 is symmetrically provided with placement grooves 8 that match the sampling cup 10. The inner wall of the placement grooves 8 is symmetrically provided with mounting grooves 15, and a limiting mechanism 9 is installed within the mounting grooves 15. The limiting mechanism 9 includes a pressing block 91 and a third spring 92. The pressing block 91 is slidably installed within the mounting groove 15 and elastically connected to the inner wall by the third spring 92. The top of the clamping end of the pressing block 91 is inclined. When the operator presses down to place the sampling cup 10, the bottom of the cup body forces the pressing block 91 to retract outwards along the inclined surface. After the cup body falls in, the restoring force of the third spring 92 causes the pressing block 91 to tightly clamp the outer wall of the sampling cup 10, ensuring the stability of the sampling cup 10. Example

[0029] refer to Figures 2-7 Based on Example 1, this embodiment focuses on detailing the internal components and linkage relationship of the intelligent sensor detection component 6 and the cleaning component 7 of this device.

[0030] The intelligent sensor detection assembly 6 is fixed to the side wall of the base 1 by the mounting bracket 5. It includes an n-shaped bracket 61 and an electric telescopic rod 65 located at the top. A mounting cylinder 62 is slidably installed inside the n-shaped bracket 61. With the cooperation of the guide block 63 and the guide groove 64, the mounting cylinder 62 can only slide in the vertical direction. Several limiting grooves 67 are symmetrically opened on the inner wall of the mounting cylinder 62, and corresponding limiting sliders 69 are slidably installed. A guide shaft 68 passes vertically through the limiting slider 69, and a No. 1 spring 610 is sleeved between the bottom wall of the limiting slider 69 and the bottom of the groove. Multiple sets of sensor bodies 612 for different components are fixed to the side wall of the limiting slider 69 by the connecting shaft 611. The bottom end of the sensor body 612 has an integrated detection head 613.

[0031] To enable independent selection and pressing operation for specific types of sensors, a pressing control mechanism 66 is installed at the center of the mounting cylinder 62. The movable end of the electric telescopic rod 65 vertically passes through and is fixedly connected to the mounting block 661 of the pressing control mechanism 66. The side wall of the mounting block 661 has a storage slot 662 corresponding to the position of each sensor body 612. A rotating plate 663 is rotatably installed in the slot. The inner side of the rotating plate 663 is hinged to a sliding block 665 that can extend and retract within the storage slot 662 via a connecting plate 664. A fixed optical axis 666 runs longitudinally through the center of the sliding block 665. An annular magnetic block 668 is fixed on the top surface of the sliding block 665, and an electromagnet 669 is installed at the top of the optical axis 666. The two are kept in an elastic pushing state by a second spring 667. The magnetic poles of the electromagnet 669 and the magnetic block 668 are set as the same magnetic poles.

[0032] In addition, to avoid cross-contamination during multiple tests, a cleaning component 7 is connected to the bottom of the mounting cylinder 62. The bottom wall of the mounting cylinder 62 has through holes 21 corresponding to the protrusions of each test head 613, and the bottom side wall has threads 20 for screwing onto a threaded cap 71. The threaded cap 71 has a storage groove 72 inside, containing a single piece of absorbent sponge 73, and an arc-shaped through groove 74 is formed on the bottom wall corresponding to the absorbent sponge 73. An annular pipe 75 is installed on the outer ring of the side wall of the threaded cap 71, connected to an external water source via a connecting pipe 77, allowing water to be sprayed at high pressure from multiple nozzles 76 on the inner wall of the annular pipe 75 into the inner cavity at the bottom of the threaded cap. An annular baffle 78 at the bottom of the inner cavity is inclined with the outer side higher than the inner side and matches the top edge of the sampling cup 10, allowing the rinsed water to fall into the sampling cup 10 along the annular baffle 78. Example

[0033] This embodiment further describes in detail the complete workflow of the device when performing automated intelligent detection and self-cleaning of various types of food.

[0034] In operation, the turntable 2 rotates intermittently under the drive of the bottom groove wheel mechanism, and smoothly transports the sampling cup 10 containing the liquid food to be tested to the front detection station of the camera 12.

[0035] The camera 12 records and identifies the label in the label insert 22 on the side wall of the sampling cup 10 in real time. The built-in system of the touch screen control panel 4 quickly compares and processes the data to determine the type of sample in the current sampling cup 10 and decides which one or more sensor bodies 612 should be matched with the sample for data detection.

[0036] Based on detection decisions, the system individually energizes the electromagnet 669 corresponding to this sensor in the press control mechanism 66. According to the magnetic principle of like poles repelling each other, the electromagnet 669 generates a strong repulsive force on the magnetic block 668 below. This repulsive force overcomes the elastic force of the second spring 667, forcing the sliding block 665 to slide downwards along the optical axis 666. The sliding block 665 then pulls the connecting plate 664, folding and rotating the connected rotating plate 663 from a vertically concealed state to a horizontally outward protruding state. At this time, the rotating plates 663 of the other unenergized electromagnet groups remain retracted in the storage slot 662.

[0037] The system controls the electric telescopic rod 65 to begin extending downwards at a uniform speed. During the extension of the electric telescopic rod 65, the mounting cylinder 62 first moves downwards under its own weight until the annular baffle 78 on the threaded cap 71 abuts against the top of the sampling cup 10. The electric telescopic rod 65 continues to extend, thereby driving the mounting block 661 to descend along the mounting cylinder 62. At this time, the rotating plate 663, which is in a horizontal state, can abut against the top of the corresponding sensor body 612. As it continues to press down, the corresponding limit slider 69 overcomes the elastic force of the first spring 610 and slides downwards along the guide shaft 68, pushing the corresponding detection head 613 downwards in sequence, passing through the through hole 21, the absorbent sponge 73, and the arc-shaped through groove 74, and accurately inserting it into the food solution in the sampling cup 10 below for static reading, completing the targeted detection project, and displaying the results through the touch screen control panel 4.

[0038] After the test is completed, the reset and cleaning process begins. The electric telescopic rod 65 retracts and rises automatically according to the instructions. After the pressure from above is released, the limit slider 69 moves the detection head 613 upward under the elastic force of the first spring 610. When the detection head 613 leaves the food liquid surface and enters the inner cavity of the cleaning component 7, external water is simultaneously injected into the ring pipe 75 under high pressure from the connecting pipe 77. Then, it is sprayed from the densely distributed nozzles 76 onto the outer surface of the detection head 613 to peel off the attached viscous food liquid and residue. The rinsed water flows into the sampling cup 10 along with the ring baffle 78 and is removed together with the sampling cup 10 when the staff removes it later. During the process of the detection head 613 continuing to move upward and completely reset, there are still cleaning water droplets on its outer wall. Since it must pass through the storage tank 72 in the opposite direction, the highly absorbent sponge 73 can fully wipe and absorb the water attached to the outer wall of the detection head 613 to ensure that the sensor probe is dry. Finally, the electromagnet 669 is de-energized, and the rotating plate 663 retracts to its original position under the action of the second spring. The equipment then awaits the next sample level determination and sampling test. Simultaneously, the cleaning component 7 can be periodically removed, and the absorbent sponge 73 can be replaced to ensure effective drying.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
