Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a food quality detection device. Background Art

[0002] In practical applications, food quality testing devices often require selecting appropriate detection principles and technologies based on specific testing needs and scenarios. For example, in agricultural product quality and safety monitoring, pesticide residue detectors, based on chemical and spectral analysis, may be used; livestock product quality and safety monitoring may utilize equipment such as veterinary drug residue detectors; and during food processing and production, a combination of multiple testing methods may be necessary to ensure food safety and quality.

[0003] The food safety detector is one of the many food quality testing devices. The food safety detector is mainly based on the combination of multiple analytical technologies and detection methods. Its workflow usually includes three main parts: sample processing, detection module, and data analysis. The detection module is the core part of the food safety detector and integrates a variety of detection technologies and sensors. These technologies include but are not limited to spectral analysis, electrochemical analysis, biosensing, etc. According to different detection requirements, the detection module will use different detection principles to efficiently and quickly identify and quantitatively analyze harmful substances in the sample. When conducting the test, food samples are collected according to the test requirements and appropriately pretreated as required, such as grinding, dilution, filtration, etc., to ensure that the sample is suitable for testing; the processed sample is placed in the sample slot or test tube according to the requirements of the instrument manual, and ensure that the sample is in full contact with the detection component.

[0004] In the existing technical solutions, after each test is completed, the food safety tester is cleaned and maintained to keep the instrument clean and in normal use condition; this includes cleaning the sample tank, sensors and other components, and replacing the used reagents and consumables; when cleaning, generally speaking, most people start from the outside of the instrument, such as the sample tank and other components, and then consider cleaning the more delicate internal components, such as sensors. Only in this way can the sample tank and sensors be manually cleaned in two times. Therefore, the existing cleaning method after each test is completed has the problems of cumbersome operation and large workload, resulting in a large waste of manpower and time. Summary of the Invention

[0005] The purpose of the present utility model is to provide a food quality detection device, which can greatly shorten the time required for the entire cleaning process by cleaning the sensor and the sample tank simultaneously; when the sample tank and the sensor are cleaned at the same time, the waiting time of the sequence is avoided, making the entire post-detection maintenance process more compact and efficient, thereby avoiding the problem that manual cleaning requires human participation, is time-consuming and requires additional labor costs, so as to solve the problems raised in the above-mentioned background technology.

When the sample tank and sensor are cleaned at the same time, the waiting time for the order of cleaning is avoided, making the entire post-test maintenance process more compact and efficient. The synchronous automatic cleaning operation greatly simplifies the operation process, reduces the skill requirements of the operator, and at the same time, reduces the operational errors caused by cumbersome operation steps. This can avoid the problem of manual cleaning requiring human intervention, which is time-consuming and requires additional labor costs;

[0017] 2. The utility model automatically cleans the sample slot and sensor through a cleaning spray, and automatically dries the sample slot after cleaning, which can improve operational efficiency and reduce errors and risks caused by manual intervention.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides a technical solution:

[0030] See also Figures 1 to 4A food quality testing device includes an assembly housing 1, with a sealing cover 2 rotatably mounted on the upper end surface of the assembly housing 1. Three sample slots 4 are mounted within the assembly housing 1, each of which is sealed and fixedly mounted with a sensor 6. A detection mechanism 3 is fixedly mounted within the assembly housing 1. The detection mechanism 3 is the core component of the food safety tester and integrates multiple detection technologies and sensors 6. These technologies include, but are not limited to, spectral analysis, electrochemical analysis, and biosensing. Depending on the different detection requirements, the detection module will adopt corresponding detection principles, such as using optical sensors to detect chemical changes in the sample, or using electrochemical sensors to measure changes in electrical parameters such as current and potential. During the detection process, the sensor 6 generates signals based on the chemical, physical, or biological characteristics of the sample. These signals may be optical signals, electrical signals, etc. The instrument captures these signals and converts them into processable digital signals for subsequent data analysis. The captured signals are processed using built-in software algorithms, including filtering, amplification, and digitization, to improve the signal-to-noise ratio and accuracy of the signals. Based on the processed signals, combined with a preset standard curve or model, the content or concentration of the substance to be tested in the sample is calculated. The calculated results are compared with the set safety standards or regulatory requirements to determine whether the food is qualified. The above is the existing technology and will not be described in detail. The bottom end of the sample tank 4 is connected to the electromagnetic discharge pipe 8. The interior of the assembly housing 1 is provided with an assembly groove 5 corresponding to the sealing cover 2. The assembly groove 5 is fixedly connected to the sample tank 4. The interior and exterior of the sample tank 4 are provided with a transmission component 9.

[0031] A cleaning assembly 7 is provided on the inside and outside of the sample slot 4. The cleaning assembly 7 includes a servo motor 701 fixedly mounted on the bottom end of the sample slot 4. A transmission shaft 702 is fixedly mounted on the power output end of the servo motor 701. Symmetrically distributed sensor cleaning racks 705 are fixedly mounted on the side walls of the transmission shaft 702. Second soft brushes 706 are fixedly mounted on the side walls of the sensor cleaning racks 705 that are close to each other. A slot wall cleaning rack 703 fixedly mounted on the shaft wall of the transmission shaft 702 is provided on the side facing away from each other. A first soft brush 704 is fixedly mounted on the side wall of the slot wall cleaning rack 703 close to the sample slot 4.

[0032] By adopting the above technical solution, when in use, the sealing cover 2 is rotated to open, so that the processed test sample can be placed in the sample slot 4. Through the contact between the sensor 6 in the sample slot 4 and the sample, the test data can be transmitted to the detection mechanism 3, and the sample can be tested by the detection mechanism 3. After the test is completed, the electromagnetic discharge pipe 8 is started, and the tested sample can be discharged through the electromagnetic discharge pipe 8. After each test is completed, the sample slot 4 and the sensor 6 of the food safety detector are cleaned, and the servo motor 701 is started. The servo motor 701 can drive the transmission shaft 702 to rotate. The rotation of the drive shaft 702 drives the sensor cleaning rack 705 and the tank wall cleaning rack 703 to rotate. The first soft brush 704 of the tank wall cleaning rack 703 engages with the inner wall of the sample tank 4, automatically cleaning the inner wall of the sample tank 4. Simultaneously, the sensor cleaning rack 705 is located above and below the sensor 6, and the second soft brush 706 of the sensor cleaning rack 705 engages with the end surface of the sensor 6, thereby cleaning the end surface of the sensor 6 through rotation. The simultaneous cleaning of the sensor 6 and the sample tank 4 significantly shortens the cleaning process. When the sample tank 4 and sensor 6 are cleaned simultaneously, the waiting time of the sequence is avoided, making the entire post-test maintenance process more compact and efficient. Synchronous cleaning ensures that the sample tank 4 and sensor 6 are cleaned immediately after the test is completed, preventing residue from lingering inside the device for an extended period of time and reducing the risk of cross-contamination. This is crucial for maintaining the accuracy and reliability of the device. The simultaneous automatic cleaning operation greatly simplifies the operation process, reduces the operator's skill requirements, and reduces the risk of operator errors caused by cumbersome procedures. This can avoid the problem of manual cleaning requiring human intervention, taking a long time and requiring additional labor costs.

[0033] Specifically, such as Figure 1 、 Figures 5 to 7As shown, the transmission component 9 includes a connecting sleeve 901 rotatably mounted on the outside of the bottom end of the transmission shaft 702, a transmission channel 903 is opened inside the transmission shaft 702, and a connecting hole 902 is opened on the outer wall of the transmission shaft 702 inside the connecting sleeve 901, and the connecting sleeve 901 is connected to the transmission channel 903 through the connecting hole 902; the transmission component 9 also includes a groove wall cleaning channel 904 opened inside the groove wall cleaning frame 703, and a plurality of first spray holes 905 are opened on the side wall of the groove wall cleaning frame 703 near the first soft brush 704; the sensor cleaning A sensor cleaning channel 906 is provided inside the cleaning frame 705, and a plurality of second spray holes 907 are provided on the side wall of the sensor cleaning frame 705 near the second soft brush 706; a side wall cleaning spray hole 908 is provided at the top end of the side wall of the sensor cleaning frame 705 located at the second soft brush 706, and the side wall cleaning spray hole 908 is interconnected with the transmission channel 903 through the sensor cleaning channel 906. A cleaning spray valve pipe 10 and a drying valve pipe 11 are installed on the side wall of the connecting sleeve 901, and the cleaning spray valve pipe 10 is located below the drying valve pipe 11.

[0034] By adopting the above technical solution, when in use, the cleaning spray valve tube 10 and the drying valve tube 11 are respectively connected to the cleaning spray supply tube and the hot air supply tube, so that the cleaning spray and hot air can be supplied to the sample tank 4 and the sensor 6 respectively. When cleaning is required, the solenoid valve on the cleaning spray valve tube 10 is opened to connect the cleaning spray valve tube 10 with the connecting sleeve 901, so that the cleaning spray can be transported to the transmission channel 903 through the connecting sleeve 901 and the connecting hole 902. At the same time, the transmission channel 903 is interconnected with the multiple first spray holes 905 on the tank wall cleaning rack 703. In this way, when the tank wall cleaning rack 703 rotates, the cleaning spray can be sprayed onto the first soft brush through the first spray hole 905 704, in the process of cleaning the first soft brush 704, the inner wall of the sample tank 4 is cleaned at the same time, thereby ensuring the cleaning effect of the inner wall of the sample tank 4. Similarly, the transmission channel 903 can be connected to the multiple second spray holes 907 on the sensor cleaning rack 705. When the sensor cleaning rack 705 rotates, the cleaning spray is sprayed onto the second soft brush 706 through the second spray hole 907. In the process of cleaning the second soft brush 706, the end face of the sensor 6 is cleaned at the same time, and the side wall cleaning spray hole 908 opened can directly spray the cleaning spray onto the inner wall of the sample tank 4 corresponding to the sensor 6, so that the flushing process of the sample tank 4 corresponding to the sensor 6 can be realized, thereby ensuring The effect of comprehensive cleaning of the interior of the sample tank 4 is that when the cleaning is completed, the electromagnetic discharge pipe 8 is opened, and the cleaned liquid can be discharged through the electromagnetic discharge pipe 8. At this time, the cleaning spray valve pipe 10 can be closed, and the drying valve pipe 11 is opened. The drying valve pipe 11 is connected to the hot air supply pipe, so that hot air can be sprayed into the sample tank 4 and the sensor 6 through the supply of the cleaning spray, so that the cleaned sample tank 4 and the sensor 6 can be quickly dried. In this way, the sample tank 4 and the sensor 6 are automatically cleaned by the cleaning spray, and the automatic drying process after cleaning is combined with the automatic drying process, which can improve the operating efficiency and reduce the errors and risks caused by manual intervention; and the cleaning spray usually contains high-efficiency cleaning ingredients , which can quickly dissolve and remove stains, grease and other residues on the surface of the sample slot 4 and the sensor 6; the cleaning spray can complete the cleaning task faster, and fast cleaning means that the operator can prepare for the next test faster, thereby improving work efficiency; and the cleaning spray can penetrate into the tiny gaps and hard-to-reach areas on the surface of the sample slot 4 and the sensor 6, thereby achieving more thorough cleaning; combined with the drying process, it can ensure that the moisture remaining on the sample slot 4 and the sensor 6 during the cleaning process is completely removed; in the scenario of continuous testing, the drying process is performed simultaneously after cleaning without additional waiting time; this helps to improve the overall detection efficiency and enable the equipment to be put into the next detection more quickly.

[0035] Working principle: When in use, connect the cleaning spray valve pipe 10 and the drying valve pipe 11 to the cleaning spray supply pipe and the hot air supply pipe respectively, so that the cleaning spray and hot air can be supplied to the sample tank 4 and the sensor 6 respectively. When cleaning is needed, start the servo motor 701. The servo motor 701 can drive the transmission shaft 702 to rotate. The rotation of the transmission shaft 702 can drive the sensor cleaning rack 705 and the tank wall cleaning rack 703 to rotate. The first soft brush 704 of the tank wall cleaning rack 703 fits the inner wall of the sample tank 4, thereby automatically cleaning the inner wall of the sample tank 4. At the same time, the sensor cleaning rack 70 5 is located on the upper and lower sides of the sensor 6, and the second soft brush 706 of the sensor cleaning frame 705 is in contact with the end surface of the sensor 6, so that the end surface of the sensor 6 can be cleaned by rotation. When the cleaning component 7 is started, the solenoid valve on the cleaning spray valve pipe 10 is opened synchronously, so that the cleaning spray valve pipe 10 is connected to the connecting sleeve 901, so that the cleaning spray can be transported to the transmission channel 903 through the connecting sleeve 901 and the connecting hole 902. At the same time, the transmission channel 903 is connected to the multiple first spraying holes 905 on the tank wall cleaning frame 703, so that when the tank wall cleaning frame 703 rotates, the cleaning spray can be sprayed into the transmission channel 903 through the connecting sleeve 901 and the connecting hole 902. The first spray hole 905 sprays the cleaning spray onto the first soft brush 704. During the cleaning process of the first soft brush 704, the inner wall of the sample tank 4 is cleaned at the same time, thereby ensuring the cleaning effect of the inner wall of the sample tank 4. Similarly, the transmission channel 903 can be connected to the multiple second spray holes 907 on the sensor cleaning rack 705. When the sensor cleaning rack 705 rotates, the cleaning spray is sprayed onto the second soft brush 706 through the second spray hole 907.
