Description

Technical Field

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

[0002] After food is produced in a food factory, in order to ensure that the produced food meets the legal safety, quality and standard requirements, food samples will be analyzed and inspected through food testing equipment. Food testing is one of the important measures to protect the health and rights of consumers;

[0003] When testing food, in order to improve the accuracy of food testing, the food testing device will perform various tests on the food, such as spectral analysis, odor detection, etc. Among them, odor detection uses an electronic nose to distinguish the odor characteristics of different foods, detect the freshness of food, quality control, and detect possible food contamination or deterioration;

[0004] During the process of the above-mentioned food detection device actually performing food detection through an electronic nose, it was found that when the food detection device detects multiple food samples, the odor of the previously detected food samples will remain near the electronic nose, affecting the accuracy of subsequent food sample detection. At the same time, after the food samples are placed, the odor will overflow and affect the surrounding food samples, which is not conducive to the continuous detection of food samples.

[0005] In summary, there is a need for a food testing device that is conducive to continuous testing. Utility Model Content

[0024] Embodiment 1

[0025] In order to solve the technical problems in the background technology, a food detection device which is conducive to continuous detection is provided as follows:

[0026] Combination Figure 1-Figure 4As shown, the utility model provides a food detection device that is conducive to continuous detection, including an installation box 1, a detection mechanism 2 for detecting food samples is provided on the top surface of the installation box 1, a sample pushing mechanism 3 is provided in the middle of the installation box 1, and the sample pushing mechanism 3 can continuously send a placing mechanism 4 for placing food samples into the detection mechanism 2, so that the food detection device can continuously detect food, and a placing mechanism 4 for placing food samples is provided inside the sample pushing mechanism 3, and the placing mechanism 4 can place food samples that need to be detected to avoid the situation where the odor of the food samples overflows and affects the detection accuracy of the food detection device. The detection mechanism 2 includes a detection box 21, a mounting frame 22, an electronic nose 23 and a cross plate 24. An inlet and outlet groove is provided on the side of the bottom of the detection box 21. The opening of the inlet and outlet groove is convenient for the sample pushing mechanism 3 to send the placing mechanism 4 for placing food samples to the bottom of the electronic nose 23 for detection. A mounting frame 22 is provided on the upper inner side of the detection box 21 The rack 22 is provided with an electronic nose 23 on the bottom surface of the middle part of the mounting rack 22. The electronic nose 23 can distinguish the smell characteristics of the food sample and identify possible food contamination, corruption or authenticity problems. A horizontal plate 24 is provided below the electronic nose 23. An air guide port 25 is provided in the middle of the horizontal plate 24. The air guide port 25 can guide the gas volatilized by the food sample in the sample placement mechanism 4 to the detection position of the electronic pen. The air guide port 25 is located below the electronic nose 23. The sample pushing mechanism 3 includes a motor 31, a turntable 32 and a mounting port 33. The motor 31 is provided inside the mounting box 1. The motor 31 can provide power for the rotation of the turntable 32. The output end of the motor 31 is provided with a turntable 32. The turntable 32 is located on the top surface of the mounting box 1. The edge of the turntable 32 is provided with a mounting port 33. The mounting ports 33 are distributed in a ring. The mounting ports 33 distributed in a ring are convenient for placing multiple sample placement mechanisms 4, which is beneficial for the food detection device to continuously detect multiple food samples.

[0027] In this embodiment, the sample placing mechanism 4 is located inside the installation opening 33. A plurality of sample placing mechanisms 4 are provided above the installation box 1. The sample placing mechanisms 4 are provided corresponding to the installation opening 33. The sample placing mechanism 4 placed inside the installation opening 33 enables the sample placing mechanism 4 to follow the rotation and movement of the turntable 32 when the food detection device performs food detection.

[0028] In this embodiment, the sample placing mechanism 4 includes a sample placing tube 41, a tube cover 42, a baffle 1 43 and a baffle 2 44. A tube cover 42 is provided on the top of the sample placing tube 41, and the tube cover 42 is snap-connected with the sample placing tube 41. Vents are provided on the inner bottom of the sample placing tube 41 and inside the tube cover 42. The vents are arranged in a ring inside the tube cover 42 and at the bottom of the sample placing tube 41. A baffle 1 43 is provided on the top of the vent. The baffle 1 43 is rotatably hinged to the vent. The baffle 1 43 rotatably hinged to the vent can seal and isolate the gas volatilized from the food sample inside the sample placing tube 41. At the same time, when the placing mechanism performs food detection, the vent is opened by rotating to bring the volatilized gas from the food sample into contact with the electronic nose 23 for detection.

[0029] The implementation principle of the first embodiment is as follows: when the food detection device performs food detection, the food sample is placed in the sample placing mechanism 4, then the motor 31 in the sample pushing mechanism 3 drives the turntable 32 to rotate, and the sample placing mechanism 4 in the mounting port 33 will follow the turntable 32 to rotate and move to the inside of the detection box 21 of the detection mechanism 2, then the electric fan 14 inside the mounting box 1 will send air into the sample placing mechanism 4, and the air will push the baffle 1 43 to open the vent, so that the air can flow in the sample placing tube 41 and push the volatilized gas of the food sample in the sample placing tube 41 to contact with the electronic nose 23, so as to achieve the effect of detecting food, and during the detection process, the motor 31 in the sample pushing mechanism 3 drives the turntable 32 to rotate continuously, so as to sequentially send the sample placing mechanism 4 containing the food sample to the inside of the detection box 21 for detection, thereby facilitating the food detection device to continuously detect multiple food samples.

[0030] Embodiment 2

[0031] like Figure 1-Figure 3 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0032] In order to enable the wearable component to be carried around, the present embodiment provides the following design:

[0033] An air outlet box 26 is provided on the top side of the detection box 21, and a detection area is formed below the horizontal plate 24. The height of the detection area is the same as that of the sample placing mechanism 4. The detection area with the same height as that of the sample placing mechanism 4 can ensure that the gas in the sample placing mechanism 4 enters the top of the horizontal plate 24 through the air guide port 25 in the middle of the horizontal plate 24 and contacts the electronic nose 23 for detection;

[0034] In this embodiment, a partition 11 is provided inside the installation box 1, an air intake filter 12 is provided on the side of the installation box 1, a mounting plate 13 is provided on the side of the air intake filter 12, and an electric fan 14 is provided in the middle of the mounting plate 13. The setting of the electric fan 14 can provide power for the gas flow inside the installation box 1, so that air can enter the lofting mechanism 4;

[0035] As an improvement of the above scheme, an air intake area is formed between the partition 11 and the mounting plate 13, and an upper air port 15 is opened at the top of the air intake area. The upper air port 15 can deliver the air in the air intake area from the bottom of the lofting mechanism 4 into the interior of the lofting mechanism 4. The upper air port 15 is arranged corresponding to the air guide port 25. The diameter of the air guide port 25 is smaller than the diameter of the lofting tube 41. The air guide port 25 smaller than the diameter of the lofting tube 41 can ensure that the air stably enters the interior of the lofting tube 41.

[0036] The implementation principle of the second embodiment is as follows: when the food detection device performs food detection, the electric fan 14 works to draw air from the outside of the installation box 1 into the air intake area through the air intake filter 12. Then, the air in the air intake area flows upward from the upper air port 15 into the sampler tube 41 of the sampler mechanism 4. Then, the air is mixed with the gas volatilized from the food sample in the sampler tube 41 and contacts the electronic nose 23 through the air guide port 25. After the electronic nose 23 detects the gas volatilized from the food sample, the air is discharged from the device through the air outlet box 26. After the food sample is detected, the electric fan 14 drives the air to flow continuously again, which can discharge the gas of the food sample remaining in the detection box 21, thereby facilitating the device to continuously perform food detection.
