[0021] An embodiment of the present utility model provides a rapid freshness detection device for chilled fresh pork, as Figures 1-4 shown, the rapid freshness detection device for chilled fresh pork includes: a base 1; a conveyor belt 2, the conveyor belt 2 is installed on the top of the base 1, and the conveyor belt 2 is used for conveying chilled fresh pork; a plurality of cylinders 3, a plurality of the cylinders 3 are all fixed on the base 1; a protective housing 4, the protective housing 4 is installed on the output rods of the plurality of cylinders 3; an electronic nose 5, the electronic nose 5 is installed in the protective housing 4, and an air extraction probe 11 is provided at the bottom of the electronic nose 5; a fixed cylinder 10, the fixed cylinder 10 is fixed in the protective housing 4 and sleeved outside the air extraction probe 11, and an extension pipe extending to the outside is installed on the fixed cylinder 10; a cleaning assembly, the cleaning assembly is arranged on the base 1, and the cleaning assembly is used for cleaning the conveyor belt 2.

[0022] In this embodiment, the conveyor belt 2 is used to convey chilled fresh pork. The design of the conveyor belt 2 enables the pork to continuously and automatically pass through the detection area, improving the detection efficiency. The height and position of the protective shell 4 and the electronic nose 5 can be adjusted by the movement of the output rod of the cylinder 3, improving the flexibility and accuracy of the detection. The protective shell 4 is used to protect the internal electronic nose 5 from external interference and pollution. The electronic nose 5 extracts odor characteristic information using bionic olfactory technology and obtains a discrimination result through recognition methods and means. This technology can quickly and accurately judge the freshness of pork. The design of the fixed cylinder 10 and the extension pipe can ensure the freshness and purity of the sampled gas, avoiding the influence of the indoor environment on the detection result. Debris and dirt are likely to remain on the conveyor belt 2, and the setting of the cleaning component can ensure the cleanliness of the conveyor belt 2 and avoid its interference with the detection result.

[0023] In a further preferred embodiment of the present utility model, the cleaning component includes a water tank 14, a water pump 16, and a liquid spraying pipe 18. The water tank 14 is fixed on the top of the base 1. The water tank 14 is sleeved outside the conveyor belt 2. The water pump 16 is installed on the base 1 and is located inside the water tank 14. The liquid spraying pipe 18 is fixed at the liquid discharging end of the water pump 16. A plurality of spray heads are installed on the liquid spraying pipe 18, and all the spray heads are located directly below the conveyor belt 2.

[0024] In this embodiment, the design of the water tank 14 enables the water tank 14 to conveniently store the cleaning liquid and ensures that the cleaning liquid can directly act on the surface of the conveyor belt 2. The function of the water pump 16 is to extract the cleaning liquid in the water tank 14 and pressurize it to the liquid spraying pipe 18. When the conveyor belt 2 passes by, the spray heads can directly spray the cleaning liquid onto its surface to wash the conveyor belt 2.

[0025] In a further preferred embodiment of the present utility model, a brush rod 19 and a scraping plate 20 are fixed on the inner wall of the water tank 14. The brush rod 19 is in contact with the surface of the conveyor belt 2. Two silica gel sheets 21 are fixed on the top of the scraping plate 20, and both silica gel sheets 21 can be in contact with the bottom of the conveyor belt 2. The silica gel sheets 21 are used to scrape off moisture.

[0026] In this embodiment, when the conveyor belt 2 passes by, the brush rod 19 can assist in cleaning the surface of the conveyor belt 2 and removing stubborn stains and impurities attached to the surface. When the conveyor belt 2 passes by the scraping plate 20, the silica gel sheets 21 can effectively scrape off the moisture remaining at the bottom of the conveyor belt 2, ensuring that the conveyor belt 2 can remain dry in subsequent work and preventing the moisture from affecting the detection result.

[0027] In a further preferred embodiment of the present utility model, two baffles 15 are fixed to the top of the water tank 14, and the two baffles 15 are respectively in contact with both sides of the conveyor belt 2. Observation windows 13 are provided on both sides of the protective shell 4.

[0028] In this embodiment, the baffle 15 prevents the splashing and waste of the cleaning liquid, and at the same time prevents the pork from falling off the conveyor belt 2. The observation window 13 allows the operator to directly observe the working state and detection results of the electronic nose 5 without opening the protective shell 4, thereby improving the convenience and safety of operation.

[0029] In a further preferred embodiment of the present utility model, a blower 6 is installed on the top of the electronic nose 5. An exhaust pipe 7 and an intake pipe 8 are respectively fixed to the exhaust end and the intake end of the blower 6. The exhaust end of the exhaust pipe 7 extends into the fixed cylinder 10. Branch pipes 9 are installed on both the exhaust pipe 7 and the intake pipe 8, and both of the two branch pipes 9 extend to the outside of the room.

[0030] In this embodiment, the blower 6 is used to provide the power for gas flow. The intake pipe 8 cooperates with the branch pipe 9 to introduce fresh air from the outside of the room to keep the air in the protective shell 4 fresh. Only through the intake pipe 8 can the gas beside the chilled pork be extracted. The design of the branch pipe 9 can ensure the smooth flow of gas and avoid the pollution of the indoor environment.

[0031] In a further preferred embodiment of the present utility model, electric valves 12 are provided on both the exhaust pipe 7, the intake pipe 8 and the two branch pipes 9. The bottom of the protective shell 4 can be in contact with the top of the conveyor belt 2.

[0032] In this embodiment, the electric valve 12 can accurately control the gas flow to ensure the accuracy and controllability of gas flow during the detection process. The bottom of the protective shell 4 can be in contact with the top of the conveyor belt 2, which can ensure that a relatively enclosed space is formed between the protective shell 4 and the conveyor belt 2 during the detection process, reducing the interference of the external environment on the detection results.

[0033] In a further preferred embodiment of the present utility model, a filter sleeve 17 is sleeved on the liquid inlet end of the water pump 16. A sewage discharge pipe is installed on one side of the water tank 14, and a valve is provided on the sewage discharge pipe.

[0034] In this embodiment, the function of the filter sleeve 17 is to filter the cleaning liquid in the water tank 14 to prevent impurities from entering the water pump 16, ensure the normal operation of the water pump 16 and extend its service life. The design of the sewage discharge pipe and the valve thereon enables the user to conveniently discharge the sewage or impurities in the water tank 14 to keep the inside of the water tank 14 clean and hygienic.

[0035] In summary, compared with the related art, in this device, the detection environment of the electronic nose 5 is isolated by setting the protective shell 4 to prevent the mutual influence of the odors of chilled fresh pork from affecting the detection results. The conveyor belt 2 is provided to convey chilled fresh pork. The height of the protective shell 4 is adjusted by setting the cylinder 3, which can ensure that the pork can pass through normally when not being detected. The cleaning component is provided to clean the surface of the conveyor belt 2 to prevent the conveyor belt 2 from being contaminated by stale pork and then contaminating fresh pork again.
