For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Combine the following Figures 1 to 8 , through specific embodiments and application scenarios, a pork freshness detection device provided by the embodiment of the utility model is described in detail.

[0034] like Figure 1 and Figure 2 As shown, the utility model provides a pork freshness detection device, comprising: a housing 1, a collection device, a processing device and a display device 14. The display device 14 is fixed to the outer surface of the housing 1, and the processing device is located inside the housing 1.

[0035] The collection device includes a fluorescence collector. A fluorescence reaction component 12 is placed in the housing 1 for generating a fluorescence response with the ammonia volatilized from pork. A fluorescence probe of the fluorescence collector is fixed inside the housing 1 for collecting the fluorescence information of the fluorescence reaction component 12.

[0036] The fluorescence collector is electrically connected to the processing device, and the processing device is electrically connected to the display device 14 .

[0037] It is understandable that the traditional method of testing the freshness of pork is the sensory evaluation method, which mainly requires inspectors to judge the freshness of pork from the perspectives of vision, smell, touch and taste. This method is simple and convenient, and does not require the use of other tools and indicators, but it has relatively high requirements for the experience of the inspector. In addition, factors such as the age and physical condition of the staff will also affect the inspection results. It is highly subjective and cannot objectively monitor the freshness of pork.

[0038] It is understandable that pork will volatilize ammonia during storage. The pork freshness detection device provided by the utility model mainly determines the freshness of pork by collecting the concentration of ammonia volatilized by pork. Figure 1 , Figure 2 and Figure 3 As shown, the housing 1 is rectangular. The housing 1 is small in size and can be easily carried. Figure 1 , Figure 4 and Figure 5 As shown, the housing 1 is provided with a detachable film box 11. The film box 11 is provided with a receiving groove. The fluorescent reaction element 12 is received in the receiving groove.

[0039] The fluorescent reaction element 12 can generate a fluorescent response with ammonia in the air, and can present different fluorescent signals as the concentration of ammonia in the air changes. The housing 1 is provided with a plurality of vents. The plurality of vents are connected to the outside world so that ammonia in the air can enter the housing 1 and react with the fluorescent reaction element 12. Optionally, the fluorescent reaction element 12 can be a nitrogen-doped graphene quantum dot thin film fluorescent electrode with a diameter of 2.5 cm.

[0040] Furthermore, the fluorescence collector is arranged inside the housing 1, and the probe of the fluorescence collector extends to the film box 11 to collect the fluorescence information of the fluorescence reaction element 12. The fluorescence collector can convert the fluorescence information from an optical signal into an electrical signal. Optionally, the fluorescence collector can be a fluorescence sensor.

[0041] The processing device is electrically connected to the fluorescence collector and can perform calculation and analysis on the electrical signal and determine the freshness parameters of the pork. Figure 1 and Figure 3As shown, the display device 14 is mounted on the outer surface of the housing 1 and is electrically connected to the processing device. The display device 14 is used to display the freshness parameters of the pork. Optionally, the display device 14 can be a liquid crystal display screen.

[0042] When in use, the pork freshness detection device and the pork can be placed in a closed space, such as a refrigerator or a cabinet. The ammonia volatilized by the pork enters the interior of the housing 1 through the vent. The fluorescent reaction element 12 responds to the ammonia with fluorescence. At the same time, the fluorescence collector collects the fluorescence information of the fluorescent reaction element 12 and sends the fluorescence information to the processing device. The processing device determines the freshness parameters of the pork based on the fluorescence information. The display device 14 can display the freshness parameters of the pork for the user to view.

[0043] The utility model provides a pork freshness detection device. A fluorescent reaction piece 12 is arranged in an outer shell 1. Ammonia volatilized by pork can enter the inner part of the outer shell 1 and react with the fluorescent reaction piece 12. The fluorescent reaction piece 12 can present different fluorescent responses according to the concentration change of the ammonia. A fluorescent probe of a fluorescent collector is fixed inside the outer shell 1 and is used to collect fluorescent information of the fluorescent reaction piece 12. A processing device is electrically connected to the fluorescent collector and can determine the freshness parameter of the pork according to the fluorescent information. A display device 14 is electrically connected to the processing device and is used to display the freshness parameter of the pork for users to view. Users can detect the freshness of the pork in real time, which is very convenient and is conducive to promotion in real life.

[0044] The pork freshness detection device provided by the utility model further comprises a light source excitation component. The light source excitation component comprises a timer 18 and an ultraviolet lamp. The timer 18 is located on the outer surface of the housing, the ultraviolet lamp is located inside the housing 1, the timer 18 is electrically connected to the ultraviolet lamp, and the fluorescent reaction element 12 is within the irradiation range of the ultraviolet lamp.

[0045] It is understandable that the ultraviolet lamp is fixed inside the housing 1, and its irradiation field is toward the fluorescent reaction part 12. The ultraviolet lamp is used to emit ultraviolet rays to the fluorescent reaction part 12, and when the fluorescent reaction part 12 absorbs ultraviolet rays, it will emit fluorescence. Under the irradiation of the ultraviolet lamp, the fluorescent reaction part 12 responds to the ammonia volatilized by the pork, and can present different fluorescent brightness according to the concentration of ammonia. At this time, the fluorescence collector collects the fluorescence information of the fluorescent reaction part 12 in real time, and the processing device processes the fluorescence information to determine the freshness parameters of the pork. Optionally, the ultraviolet lamp is a 365nm ultraviolet lamp.

[0046] The timer 18 is installed inside the housing 1. The timer 18 is electrically connected to the ultraviolet lamp and can control the working time of the ultraviolet lamp. For example, when the ultraviolet lamp continuously irradiates the fluorescent reaction element 12 for two hours, the fluorescent reaction element 12 absorbs enough ultraviolet rays and the ultraviolet lamp can be turned off. After the ultraviolet lamp is turned off, the fluorescent reaction element 12 shows a change in brightness based on the concentration of ammonia.

[0047] Furthermore, if Figure 3 As shown, the light source excitation assembly further includes an excitation switch 13. The excitation switch 13 is fixed to the outer surface of the housing 1, and the excitation switch 13 is electrically connected to the timer 18.

[0048] It is understandable that if Figure 1 and Figure 3 As shown, the excitation switch 13 is arranged on the outer surface of the housing 1. The excitation switch 13 is electrically connected to the timer 18, and is used to control the on or off of the timer 18, thereby controlling the turning on and off of the ultraviolet lamp. The display screen 14 of the timer 18 is arranged on the outer surface of the housing 1, and is located on the same side of the housing 1 as the display device 14, so that the user can check the irradiation time of the ultraviolet lamp.

[0049] like Figure 2 and Figure 6 As shown, the outer surface of the housing 1 is provided with a first charging interface 15, and the first charging interface 15 is electrically connected to the timer 18 to power the timer 18. Optionally, the first charging interface 15 can be connected to a 12V power supply. The first charging interface 15 can be a USB interface, a Type-C interface, or a Light interface.

[0050] The temperature and humidity environment in which the pork is located has a great influence on maintaining its freshness. Furthermore, the collection device also includes a temperature and humidity sensor. The probe of the temperature and humidity sensor is fixed inside the housing 1, and is used to collect temperature and humidity information of the environment in which the pork is located. The temperature and humidity sensor is electrically connected to the processing device, and can send the temperature and humidity information to the processing device. The processing device is electrically connected to the display device 14, and can feed back the temperature and humidity information to the display device 14 for display. Thus, the temperature and humidity information of the environment in which the pork is located and its freshness parameters can be displayed accordingly in the display device 14. The user can understand the changes in the freshness of the pork under different temperatures and humidities.

[0051] Specifically, the processing device includes a control switch 16 and a main control board. Figure 1 and Figure 5 As shown, the control switch 16 is located on the outer surface of the housing 1, the control switch 16 is electrically connected to the main control board, and the temperature and humidity sensor, the fluorescence collector and the display device 14 are all electrically connected to the main control board.

[0052] It is understandable that the main control board can be a printed circuit board (PCB) known in the art, and the main control board is installed inside the housing 1. The control switch 16 is electrically connected to the main control board and is used to control the processing device, the temperature and humidity sensor, the fluorescence collector and the display device 14 to be turned on or off.

[0053] like Figure 1 and Figure 3 As shown, the pork freshness detection device provided by the utility model further includes a plurality of function keys 17. The plurality of function keys 17 are all located on the outer surface of the housing 1, and the function keys 17 are electrically connected to the timer 18 for inputting control parameters into the timer 18.

[0054] It is understandable that the multiple function keys 17 are located on the same side of the housing 1 to facilitate user operation. The multiple function keys 17 are arranged side by side. Each function key 17 is electrically connected to the main control board and is used to input control parameters to the main control board. For example, the function key 17 can be a timing key. The user presses the timing key to set the collection time of the fluorescence collector and the temperature and humidity sensor.

[0055] In some embodiments, the pork freshness detection device provided by the present invention further includes an alarm device 5. Figure 1 As shown, the alarm device 5 is fixed to the housing 1, and the alarm device 5 is electrically connected to the main control board. The main control board determines whether the current freshness parameter exceeds the threshold value based on the fluorescence information collected by the fluorescence collector. When the freshness parameter exceeds the threshold value, the main control board controls the alarm device 5 to sound an alarm to remind the user that the freshness of the pork does not meet the standard.

[0056] Optionally, the alarm device 5 is a buzzer.

[0057] Specifically, the pork freshness detection device provided by the utility model further includes a lithium battery. The lithium battery is located in the housing 1.

[0058] Figure 7 and Figure 8 They are the left and right views of the pork freshness detection equipment. Figure 7 As shown, the housing 1 is provided with a second charging interface 19, which is electrically connected to the lithium battery for charging the lithium battery. The lithium battery is connected to the power supply interface of the main control board to power the main control board and various components. Optionally, the second charging interface 19 can be a USB interface, a Type-C interface or a Light interface.

[0059] In some embodiments, the pork freshness detection device further comprises a wireless communication module. The communication interface of the wireless communication module is electrically connected to the main control board for communication with an external electronic device or computer. The main control board can send the pork freshness parameters to an external electronic device or computer through the wireless communication module for user reference.

[0060] Optionally, the wireless communication module can be a Bluetooth module, a WIFI module, a 5G module, etc. The wireless communication module is configured with an antenna, which sends radio frequency signals to the base station antenna and receives electromagnetic wave signals from the base station antenna, thereby realizing the connection between the pork freshness detection device and the external communication network. Figure 7 As shown, the housing 1 is provided with a connection hole 101 communicating with the outside. The wireless communication module is located in the connection hole 101 to ensure the communication quality of the antenna. In a specific embodiment, the wireless communication module is a wifi serial port module of the esp8266 model.

[0061] In the case where the wireless communication module is a Bluetooth module, the Bluetooth module is connected to the main control board. The Bluetooth module is adapted to the Bluetooth component on the external electronic device. Data is transmitted between the Bluetooth module and the Bluetooth component through wireless Bluetooth technology, so that the main control board sends the freshness parameter to the electronic device, and the external electronic device remotely controls the pork freshness detection device.
