Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to a puncture-type sampling detection device. Background Technology

[0002] As consumers increasingly demand food safety and quality, how to quickly and accurately determine the freshness of food, especially for large or whole foods such as meat and fruit, has become a key issue in the industry.

[0003] The existing methods for detecting food spoilage mainly fall into the following categories:

[0004] 1) Laboratory analysis methods, such as microbial culture and chemical composition analysis, are accurate, but the equipment is expensive, time-consuming, and complicated to operate, which cannot meet the needs of rapid on-site testing.

[0005] 2) Sensory evaluation method, which is to judge by sight, smell, touch, etc. This method is highly subjective, unreliable, and cannot detect the early stage of decay or internal deterioration.

[0006] 3) Portable testing equipment: Some existing portable devices indirectly determine the freshness of food by detecting volatile gases (spoilage gases) in the surrounding environment. However, existing portable testing equipment has a significant drawback: they can only detect gases on the surface of the food or inside the packaging, and cannot know the true condition inside the food, especially deep inside.

[0007] Extensive practical experience shows that the spoilage of many foods begins from the internal core, and surface test results are often lagging and misleading.

[0008] To address the aforementioned surface detection issues, existing technologies employ probes to pierce and detect the degree of food spoilage. However, the sensing element in these piercing detection methods is located at the tip of the probe, making it highly susceptible to damage and contamination during repeated piercing of solid food, resulting in short lifespan and poor reliability.

[0009] Therefore, there is an urgent need for a long-life detection device that can quickly and conveniently penetrate the interior of food for in-situ detection. Utility Model Content

[0075] Preferably, the power supply assembly 3 further includes a housing 31 ( Figure 9 (shown) and battery box 32 ( Figure 10 As shown in the diagram, the battery compartment 32 is disposed within the housing 31. For example, the housing 31 and the battery compartment 32 are snap-fitted together. Figures 9-11 As shown, the outer casing 31 and the battery box 32 are connected by a card plate and a card slot.

[0110] The above provides several embodiments of the detection components of the puncture sampling detection device, but this invention is not limited to these. This invention can employ various detection components such as fluorescence detection components, colorimetric detection components, electrochemical detection components, image detection components, and video detection components.

The puncture component 2, detection chamber 11, detection box 12, and circuit board 4 (microprocessor 41, processor 43, data transceiver module, etc.) can all be quickly replaced, facilitating maintenance and upgrades.

[0111] The following are several specific embodiments of the puncture-type sampling and detection device described in this utility model, applicable to various scenarios:

[0112] Example 1

[0113] The puncture sampling detection device is used to detect internal spoilage in food, and includes a main body 1, a detection chamber 11, a detection box 12, a puncture assembly 2, a fluorescence detection assembly, a power supply assembly 3, and a circuit board 4.

[0114] The main body 1 has a hollow structure, the detection chamber 11 is disposed inside the hollow structure, and the detection box 12 is detachably connected to the detection chamber 11.

[0115] The puncture assembly 2 includes a probe 21, which is detachably connected to the main body 1 and is a hollow probe 21, and is connected to the detection chamber 11.

[0116] The fluorescence detection component includes a fluorescent material, an ultraviolet light-emitting diode (UV-LED), and an RGB color sensor. The fluorescent material is disposed within the detection chamber 12, and the UV-LED and RGB color sensor are respectively disposed on both sides of the detection chamber 11. The UV-LED is focused on the fluorescent material. To minimize interference from stray light from the light source, the UV-LED and the RGB color sensor are positioned at a 90° angle. ° The RGB color sensor is positioned on both sides of the detection chamber 11 and captures the fluorescence signal in real time, decomposing it into the intensity values ​​of the three basic color channels 22: red (R), green (G), and blue (B).

[0117] The circuit board 4 is equipped with a microprocessor 41, a database 42, and a processor 43. The microprocessor 41 is configured to receive the detection signal from the color sensor and process it to generate detection data corresponding to the detection indicators. The database 42 is configured to store one or more standard data corresponding to one or more detection results. The processor 43 is configured to receive the detection data output by the microprocessor 41, retrieve the standard data stored in the database 42, and compare the detection data and the standard data to output the detection result corresponding to the detection data. For example, the built-in microprocessor 41 obtains the R, G, and B intensity values ​​through the RGB color sensor, but does not analyze and measure the total fluorescence intensity. Instead, it analyzes the relative proportions and changes of the three values ​​of R, G, and B (different data ranges correspond to different detection results) or their combinations to form a color fingerprint. The processor 43 compares the color fingerprint obtained by the microprocessor 41 with the standard data (corresponding to different degrees and types of decay) pre-stored in the database 42 and outputs the detection result. For example, different detection levels can be divided according to non-decay, slightly decayed, and heavily decayed, and different detection levels can also be divided according to "fresh," "slightly decayed," and "severely decayed."

[0118] The battery assembly includes a housing 31, a battery compartment 32, a battery cover 33, and a button 34. The housing 31 has an open side, and the other side of the housing 31 has a snap-fit ​​(e.g., a screw thread) for connecting to the main body 1. The other side of the housing 31 also has a through hole 20 for mounting the button 34. The button 34 is configured to control the switching of the ultraviolet light-emitting diode and the power supply. The battery compartment 32 has an open side in the same direction as the housing 31. A circuit board 4 is mounted between the housing 31 and the battery compartment 32. The battery cover 33 covers the open side.

[0119] The aforementioned puncture sampling and detection device includes a hollow puncture probe 21 and a sealed detection chamber 11 connected to the rear end of the probe 21. The detection chamber 11 contains replaceable fluorescent material, and the outside of the detection chamber 11 is equipped with an ultraviolet light-emitting diode and an RGB color sensor. The detection chamber 11, the detection box 12, the ultraviolet light-emitting diode and the RGB color sensor are all housed in the main body 1, which is conducive to the miniaturization of the device and enables it to be handheld, which is beneficial for handheld and portable detection.

[0120] The aforementioned puncture sampling and detection device inserts probe 21 into the meat product. When the putrefactive gas enters the detection chamber 11 through the needle, the ultraviolet light-emitting diode is activated to excite the fluorescent material, the RGB color sensor 111 collects the fluorescence signal, and the processor 43 automatically analyzes and outputs the degree of putrefaction.

[0121] The above provides a specific embodiment of a puncture sampling detection device for detecting internal spoilage in food. An ultraviolet LED light source is placed inside the detection chamber 11, serving as both an excitation source 112 for fluorescent materials and disinfection. However, this invention is not limited to this; the UV-LED can be replaced with a white LED, and the detection module can be loaded with colorimetric materials such as pH indicators. Furthermore, the sensing material 121 for food spoilage detection is not limited to fluorescent materials; it can also be ZnO quantum dots, carbon quantum dots, graphene quantum dots, specific organic fluorescent dyes, fluorescent metal-organic frameworks (MOFs), nano-silver, colorimetric gels, etc. One or more sensing materials 121 can be used. Furthermore, the aforementioned puncture sampling and detection device can be configured with multiple probes 21, multiple channels 22, multiple detection chambers 11 and / or multiple detection boxes 12 to simultaneously detect the spoilage of food at different depths or in different parts.

[0122] In one feasible embodiment, the circuit board 4 is provided with one or more of the following: a signal amplifier, an ADC converter, an analog divider, a digital logic device, and a color fingerprint register. The signal amplifier amplifies the signal of the RGB color sensor 111, the ADC converter converts the signal into a digital signal, the analog divider obtains the relative proportions of the three values ​​of R, G, and B, the digital logic device logically combines the relative proportions and changes to form a color fingerprint, and the color fingerprint register stores the color fingerprint.

[0124] The puncture-type sampling and detection device described in this utility model has the following advantages:

[0125] First, the detection is accurate and reliable: by sampling directly from deep inside the food through the puncture component, the problem of lag and uncertainty in surface detection is fundamentally solved, and the food can be accurately reflected in terms of spoilage.

[0126] Second, the equipment is robust and durable: all the delicate optical components and sensing materials are protected inside the robust body, and only the hard metal probes come into contact with the outside world, which greatly improves the durability and service life of the equipment.

[0127] Third, it is convenient to use and low in cost: it adopts a replaceable modular test box design, which allows users to easily replace consumables themselves, and the main unit of the device can be reused for a long time, which greatly reduces the cost of a single test.

[0128] Fourth, the results are multi-dimensional and intelligent: the innovative RGB color analysis method, compared to traditional monochrome intensity or grayscale analysis, can extract more dimensional information and distinguish the stage and even type of spoilage. Combined with wireless communication capabilities, data management and traceability can be achieved. In other words, this invention can achieve multi-dimensional RGB fluorescence analysis, a novel food analysis based on the "color fingerprint" of the R, G, and B channels of fluorescence signals, which can obtain richer and more accurate spoilage information compared to traditional detection methods.

[0129] Fifth, it has a wide range of applications: it is suitable for rapid, non-destructive (minimally destructive) on-site testing of large pieces of food in multiple fields such as meat processing, fruit storage, supermarket retail, and customs inspection and quarantine.

[0130] In summary, the puncture sampling and detection device of this utility model can quickly and conveniently penetrate into the interior of food for in-situ detection, and is a sturdy, durable, and reliable portable detection device.
