Description

Technical Field

[0001] This utility model relates to the field of rapid and non-destructive testing technology for meat quality. More specifically, this utility model relates to a portable fluorescence detection device for meat quality. Background Technology

[0002] During the processing, storage, and logistics of livestock and poultry meat, spoilage and deterioration are easily occurring, leading not only to resource waste but also potential food safety issues. Therefore, the detection and monitoring of livestock and poultry meat quality is crucial. Timely monitoring of meat freshness and safety can effectively prevent food spoilage and food safety incidents. Traditional freshness evaluation methods primarily rely on sensory assessment, physicochemical testing, and microbiological testing; however, these methods suffer from high subjectivity, high cost, and time consumption. Fluorescence detection technology, with its excellent stability, high sensitivity, and extremely low detection limit, has been widely applied in various fields. In recent years, fluorescence sensors have shown great potential in food quality monitoring, bioimaging, and drug tracking, especially in meat quality detection, where technologies based on fluorescence recognition materials have demonstrated significant advantages. Research progress indicates that fluorescence methods have broad application prospects in food quality detection. Currently, fluorescence sensing technology has made some progress in detecting single samples or single indicators, but its performance still has room for improvement. Existing fluorescence sensing devices are typically complex in structure, large in size, and lack a high degree of integration.

[0025] like Figure 1-7 As shown, this utility model provides a portable meat quality fluorescence detection device, including a housing 100. The top of the housing 100 has a first opening 101. A mixing chamber communicating with the first opening 101 is provided inside the housing 100. A rotary mixer is installed in the mixing chamber. The rotary mixer includes a base 103 installed in the mixing chamber and a cylinder 104 rotatably installed on the top of the base 103. The cylinder 104 is connected to a motor. A telescopic tube 105 is coaxially inserted into the cylinder 104. The free end of the telescopic tube 105 extends movably out of the housing 100 through the first opening 101. A detachable swab tube 106 is matched and inserted into the telescopic tube 105. A matching sampling swab 107 is placed in the swab tube 106.

[0026] In the above technical solution, the portable meat quality fluorescence detection device aims to provide an extremely convenient portable meat quality fluorescence detection device. Its design is ingenious and compact, facilitating flexible use in various scenarios. The main body of the device consists of a housing 100, with a first opening 101 at the top. Inside the housing 100, a mixing chamber is provided, tightly communicating with the first opening 101. A rotary mixer is installed within the mixing chamber, including a base 103 stably mounted within the mixing chamber, providing stable support for the entire rotary mixer. A cylinder 104 is rotatably mounted on top of the base 103. The cylinder 104 is driven by a motor and can rotate at a precise speed, thereby achieving efficient mixing of the sample placed inside. A telescopic tube 105 is coaxially inserted into the cylinder 104. The telescopic tube 105 and the cylinder 104 can be connected via a cylinder or electric screw, allowing the telescopic tube 105 to be flexibly extended and retracted according to actual operational needs. The free end of the telescopic tube 105 extends movably through the housing 100 via the first opening 101. A detachable swab tube 106 is inserted into the top of the telescopic tube 105. A matching sampling swab 107 is placed inside the swab tube 106. In use, the test material is added to the swab tube 106, and the sample is collected using the sampling swab 107. After collection, the sampling swab 107 is placed in the swab tube 106, the telescopic tube 105 is pulled to extend it, and then the swab tube 106 and the sampling swab 107 are placed together into the telescopic tube 105. The motor is turned on to drive the cylinder 104 to rotate the telescopic tube 105 and the swab tube 106, realizing an automatic mixing process. In this technical solution, the rotary mixer, stably supported by the base 103, allows the cylinder 104 to rotate at a suitable speed, efficiently mixing the sample. This ensures thorough mixing of all components in the detection solution, providing a homogeneous sample for subsequent fluorescence detection and improving the accuracy and reliability of the results. The swab tube 106 containing the sample is directly inserted into the telescopic tube 105 without complex transfer operations, directly driving the detection solution to rotate and mix within the swab tube 106. After mixing, the swab tube 106 can be easily removed for subsequent processing, greatly simplifying the sample processing procedure and improving operational efficiency.

[0027] In another technical solution, the top of the housing 100 is further provided with a second opening 201 for the swab tube 106 to be inserted. A detection cavity 200 communicating with the second opening 201 is provided inside the housing 100. An inclined partition 202 is provided inside the detection cavity 200. A collimating optical element 203 for emitting detection light of different wavelengths is installed at the second opening 201. Dispersive elements 204 for refracting detection light of different wavelengths and a detector array 206 are installed at intervals on the inclined partition 202. A focusing optical element 205 is installed on the side wall of the detection cavity 200 opposite to the inclined partition 202. In this technical solution, a second opening 201 for the swab tube 106 to be inserted is also provided at the top of the housing 100. The size of this opening is precisely matched to the swab tube 106, ensuring that the swab tube 106 can be securely inserted, laying the foundation for subsequent detection procedures. Inside the housing 100, the detection cavity 200 is tightly communicated with the second opening 201. An obliquely arranged partition is installed inside the detection cavity 200. At the second opening 201, a collimating optical element 203, such as a fiber optic collimator, is installed to emit detection light of different wavelengths. This collimating optical element 203 can precisely adjust the light emitted from the light source into a parallel beam and emit it at a specific angle and direction, ensuring that the detection light accurately illuminates the sample. These detection lights of different wavelengths can excite the sample to produce fluorescence signals with different characteristics, providing crucial information for in-depth analysis of meat quality. A dispersive element 204 and a detector array 206 are installed on the oblique partition 202. The dispersive element 204, such as a grating, can precisely separate the mixed light reflected or scattered by the sample according to the wavelength characteristics of the light, allowing light of different wavelengths to propagate along specific paths. The detector array 206, such as a CMOS detector array, consists of multiple high-sensitivity detectors that can accurately capture the different wavelength light signals separated by the dispersive element 204 and convert them into electrical or digital signals for subsequent data processing and analysis. The dispersive element 204 and the detector array 206 work closely together to accurately analyze the sample fluorescence signal, providing rich and accurate data support for judging meat quality. A focusing optical element 205 is installed on the side wall opposite the inclined partition 202 inside the detection chamber 200. This focusing optical element 205, such as a lens or mirror, focuses the light signal after passing through the sample and the dispersive element 204, projecting it more concentratedly onto the detector array 206. This not only improves the detector's light signal capture efficiency but also enhances the signal strength and stability, thereby further improving the sensitivity and accuracy of the detection and ensuring that the equipment can accurately detect even the most subtle quality differences in meat.In use, the mixed swab tube 106 is inserted into the detection cavity 200 through the second opening 201, so that the parallel light beam emitted by the collimating optical element 203 accurately illuminates the swab tube 106. The mixed light after being reflected or scattered by the sample in the swab tube 106 is transmitted downward to the dispersive element 204 for precise separation. The separated light of different wavelengths is transmitted to the focusing optical element 205 for focusing, and then concentrated and projected into the detector array 206 for precise analysis of the fluorescence signal of the sample.

[0028] In another technical solution, the motor is installed inside the base 103, and the bottom of the cylinder 104 is coaxially fixed to the motor's shaft. In this technical solution, the coaxial fixed connection between the motor's shaft and the cylinder 104 ensures the stability and reliability of the equipment operation.

[0029] In another technical solution, a telescopic cylinder is installed on the inner bottom wall of the cylinder 104, and the piston rod of the telescopic cylinder is coaxially fixed to the bottom end of the telescopic tube 105. In this technical solution, the telescopic cylinder drives the telescopic tube 105 to extend and retract. When not in operation, the telescopic tube 105 retracts for easy storage and movement. When in operation, the telescopic tube 105 extends to facilitate insertion and fixation of the swab tube 106, improving the stability of rotational operation.

[0030] In another technical solution, a liquid storage tank 300 is further provided on the top of the housing 100. The liquid storage tank 300 stores the test liquid, and a sealing cover 301 is installed on the top of the liquid storage tank 300. In this technical solution, the liquid storage tank 300 is used to store the test liquid for convenient storage, and the sealing cover 301 is designed as an electric structure for convenient control of the switch.

[0031] In another technical solution, the swab tube 106 has a double-walled structure. In this technical solution, the outer wall surface of the swab tube 106 is in close contact with the inner wall of the telescopic tube 105, which facilitates the telescopic tube 105 to drive the swab tube 106 to rotate and improves the stability of rotational operation.

[0032] In another technical solution, the sampling swab 107 contains an extraction solution, and a swab head 108 is provided at the bottom of the sampling swab 107, while a tube cap 109 is provided at the top. In this technical solution, the sampling swab 107 contains an extraction solution, and the swab head 108 can be made of flocked material, sponge, or nylon. The extraction solution can be replaced by opening the tube cap 109.

[0033] In another technical solution, a display screen 400 is mounted on the center of one side surface of the housing 100. In this technical solution, the display screen 400 is connected to a battery and a detector array 206, etc., and is used to display test results and sample images, etc.

[0034] In another technical solution, multiple control buttons 500 are installed on the lower end of one side surface of the housing 100. In this technical solution, the control buttons 500 include a power on / off button, a control / detection button, a rotary mixer button, and a liquid storage tank switch button. A circuit board is installed inside the housing 100, containing a control module and a power module. The detection module stores a linear relationship model between the sample and fluorescence intensity-related parameters such as ATP / TVC / TVB-N. The control module is electrically connected to the control button power module, the telescopic cylinder, the motor, the sealing cover, the collimating optical element 203, the detector array 206, and the display screen 400. The power on / off button controls the power supply; the control / detection button controls the switching of various optical elements within the detection chamber 200; the rotary mixer button controls the switching of the telescopic cylinder and motor; and the liquid storage tank switch button controls the opening and closing of the sealing cover, making operation convenient and quick.

After collection, place the sampling swab 107 in the swab tube 106, start the telescopic cylinder or manually pull the telescopic tube 105 to extend it, and put the swab tube 106 together with the sampling swab 107 into the telescopic tube 105. Press the rotary mixer button to start the motor to drive the cylinder 104 to rotate the telescopic tube 105 and the swab tube 106, thereby realizing the automatic mixing process. After mixing, the swab tube 106 is inserted into the detection chamber 200 through the second opening 201. The control detection button is pressed to turn on the collimating optical element 203, which emits a parallel beam of light that accurately illuminates the swab tube 106. The mixed light after being reflected or scattered by the sample in the swab tube 106 is transmitted downward to the dispersive element 204 for precise separation. The separated light of different wavelengths is transmitted to the focusing optical element 205 for focusing, and then concentrated and projected into the detector array 206 to accurately analyze the fluorescence signal of the sample. The analysis result is transmitted to the display screen 400 for display, so that the user can obtain the test results in real time and understand the freshness of the sample in a timely manner.
