Description

Technical Field

[0001] This utility model relates to the field of sample sampling technology, and in particular to a sample sampling device for detecting fungal toxins. Background Technology

[0002] Mycotoxins are toxic metabolites produced by certain fungi during their growth process. They pose a serious threat to the health of humans and animals. Mycotoxin detectors use advanced detection technology to quickly and accurately detect the content of mycotoxins in food. However, mycotoxins need to be extracted using a sampling device before detection.

[0003] Currently, mycotoxins are usually extracted by aspiration during sampling. However, the sampling device cannot control the extraction volume of mycotoxins, which can lead to excessive extraction and waste.

[0004] Meanwhile, in order to detect the fungal toxins after sampling, the fungal toxins need to be transferred. However, the holes in the sampling device that extract the fungal toxins can easily allow air to enter, causing fungal toxin contamination and thus reducing the detection quality of fungal toxins.

[0005] Therefore, we proposed a sample collection device for fungal toxin detection to address the problems mentioned above. Utility Model Content

[0006] By adjusting the height of the limiting ring, the extraction depth of the sampling tube can be controlled to prevent excessive extraction of mycotoxins and waste. Simultaneously, when the sampling tube is sampling mycotoxins, the first and second sealing plates can open due to the suction of the sampling tube, allowing the mycotoxins to be extracted into the tube. When the sampling tube is no longer extracting mycotoxins, the first and second sealing plates can close to seal the tube, preventing outside air from entering and contaminating the mycotoxins, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a sampling tube, a limiting mechanism, a first sealing mechanism, and a second sealing mechanism, wherein the limiting mechanism includes a limiting ring, which is sleeved on the outer surface of the sampling tube, and the limiting ring is used to control the amount of toxin extracted by the sampling tube, thereby preventing excessive toxin extraction and waste.

[0008] The first sealing mechanism includes a first sealing plate, and the second sealing mechanism includes a second sealing plate. The second sealing plate is installed in parallel with the first sealing plate. The first sealing plate and the second sealing plate are used to seal the extraction point of the sampling tube, so as to prevent outside air from entering the sampling tube and causing toxin contamination.

[0009] Preferably, the limiting mechanism further includes a sleeve, which is fixedly connected to the rear surface of the limiting ring, and a limiting rod is fitted inside the sleeve.

[0010] Preferably, the first sealing mechanism further includes a first rubber pad, which is connected to the side surface of the first sealing plate, and an interlocking seat is provided on the upper surface of the first sealing plate.

[0011] Preferably, the second sealing mechanism further includes a second rubber pad, which is connected to the second sealing plate. The upper surface of the second sealing plate is provided with a rubber sheet, which is fitted and connected to the fitting seat. Both the second sealing plate and the first sealing plate are made of rubber.

[0012] Preferably, the limiting ring is provided with a fastening mechanism, which includes a fastening rod. The bottom end of the fastening rod passes through the limiting ring and is fitted into the outer surface of the sampling tube. A friction pad is sleeved on the outer surface of the fastening rod, and a limiting block is fixedly connected to the top end of the fastening rod.

[0013] Preferably, the front end face of the sampling tube is provided with a connector, the connector is connected to a sampling head, and the inner wall of the sampling head is connected to a first rubber pad and a second rubber pad. The front surface of the sampling head is provided with a round hole, a piston block is fitted inside the sampling tube, a needle rod is provided on the rear surface of the piston block, a push plate is fixedly connected to the rear end face of the needle rod, and the push plate is fixedly connected to a limiting rod.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a limiting ring is pushed on the outer surface of the sampling tube. The movement of the limiting ring can drive the sleeve to move together. The movement of the sleeve allows the limiting rod to slide inside the sleeve. After the height of the limiting ring is adjusted, the fastening rod can be inserted through the limiting ring and extended into the outer surface of the sampling tube. The friction pad can increase the friction between the fastening rod and the limiting ring, so that the fastening rod can fix the limiting ring. When the pushing plate is pushing, the pushing plate can drive the limiting rod to slide inside the sleeve. The needle rod limits the depth of air escape in the sampling tube, so that the suction force can be controlled when the needle rod extracts fungal toxins.

[0016] 2. In this utility model, the first sealing plate and the second sealing plate can be fitted parallel to the round hole of the sampling head by the fitting of the rubber sheet and the fitting seat. When the needle rod is extracting fungal toxins, the first sealing plate and the second sealing plate are opened by the vacuum extraction setting in the sampling tube. The fungal toxins can be extracted into the sampling tube through the round hole of the sampling head for sampling. The rubber material of the first rubber pad and the second rubber pad has a certain elasticity, so the first rubber pad and the second rubber pad can pull the first sealing plate and the second sealing plate to return to their parallel fit and seal the round hole of the sampling tube, thereby preventing the outside air from entering the interior of the sampling tube and causing fungal toxin contamination.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 - Figure 4 As shown, it includes a sampling tube 1, a limiting mechanism 5, a first sealing mechanism 10, and a second sealing mechanism 11. The limiting mechanism 5 includes a limiting ring 501, which is sleeved on the outer surface of the sampling tube 1. The limiting ring 501 is used to control the amount of toxin extracted by the sampling tube 1, thereby preventing excessive toxin extraction and waste.

[0026] The first sealing mechanism 10 includes a first sealing plate 102, and the second sealing mechanism 11 includes a second sealing plate 112. The second sealing plate 112 is installed in parallel with the first sealing plate 102. The first sealing plate 102 and the second sealing plate 112 are used to seal the extraction point of the sampling tube 1 so as to prevent outside air from entering the sampling tube 1 and causing toxin contamination.

[0027] The overall effect of Embodiment 1 is as follows: When the sampling tube 1 is extracting mycotoxins, the sliding of the limiting ring 501 with the outer surface of the sampling tube 1 allows the height of the limiting ring 501 to be adjusted according to the volume of mycotoxins extracted. By adjusting the height of the limiting ring 501, the extraction depth of the sampling tube 1 can be adjusted and controlled to prevent excessive extraction of mycotoxins and waste. At the same time, when the sampling tube 1 is sampling mycotoxins, the first sealing plate 102 and the second sealing plate 112 can be opened by the suction of the sampling tube 1, allowing the mycotoxins to be extracted into the interior of the sampling tube 1. When the sampling tube 1 is no longer extracting mycotoxins, the first sealing plate 102 and the second sealing plate 112 can be closed to seal the sampling tube 1, preventing outside air from entering the mycotoxins and causing contamination.

[0028] Example 2, as Figure 1 - Figure 3As shown, the limiting mechanism 5 also includes a sleeve 502, which is fixedly connected to the rear surface of the limiting ring 501. A limiting rod 503 is fitted inside the sleeve 502. A fastening mechanism 9 is provided inside the limiting ring 501. The fastening mechanism 9 includes a fastening rod 901. The bottom end face of the fastening rod 901 passes through the limiting ring 501 and is fitted to the outer surface of the sampling tube 1. A friction pad 903 is sleeved on the outer surface of the fastening rod 901. A limiting block 902 is fixedly connected to the top end face of the fastening rod 901.

[0029] The overall effect of embodiment 2 is as follows: when the sampling tube 1 is extracting fungal toxins, the limiting ring 501 can be pushed on the outer surface of the sampling tube 1. The movement of the limiting ring 501 can drive the sleeve 502 to move together. The movement of the sleeve 502 allows the limiting rod 503 to slide inside the sleeve 502. After the height of the limiting ring 501 is adjusted, the fastening rod 901 can be extended through the limiting ring 501 into the outer surface of the sampling tube 1. The friction pad 903 can increase the friction between the fastening rod 901 and the limiting ring 501, so that the fastening rod 901 can fix the limiting ring 501. When the pushing plate 7 is pushing, the pushing plate 7 can drive the limiting rod 503 to slide inside the sleeve 502. The needle rod 6 limits the air discharge depth in the sampling tube 1, so that the suction force of the needle rod 6 can be controlled when extracting fungal toxins.

[0030] Example 3, as Figure 4 - Figure 5 The first sealing mechanism 10 also includes a first rubber pad 101, which is connected to the side surface of the first sealing plate 102. The upper surface of the first sealing plate 102 is provided with a fitting seat 103. The second sealing mechanism 11 also includes a second rubber pad 111, which is connected to the second sealing plate 112. The upper surface of the second sealing plate 112 is provided with a rubber sheet 113, which is fitted and connected to the fitting seat 103. Both the second sealing plate 112 and the first sealing plate 102 are made of rubber.

[0031] The overall effect achieved by embodiment 3 is as follows: the first sealing plate 102 and the second sealing plate 112 can seal the circular hole 4 parallel to and attached to the sampling head 3 by means of the rubber sheet 113 and the fitting seat 103. When the needle rod 6 is extracting fungal toxins, the first sealing plate 102 and the second sealing plate 112 are subjected to vacuum extraction in the sampling tube 1, which allows the first sealing plate 102 and the second sealing plate 112 to be opened, and the fungal toxins can be extracted. Sampling is performed by drawing samples into the sampling tube 1 through the round hole 4 of the sampling head 3. After the sampling tube 1 has finished extracting the fungal toxins, the rubber material of the first rubber pad 101 and the second rubber pad 111, which has a certain degree of elasticity, allows the first rubber pad 101 and the second rubber pad 111 to pull the first sealing plate 102 and the second sealing plate 112 back to their parallel fit, thereby sealing the round hole 4 of the sampling tube 1 and preventing outside air from entering the interior of the sampling tube 1 and causing fungal toxin contamination.

[0032] Example 4, as Figure 1 - Figure 2 As shown, the front end face of the sampling tube 1 is provided with a connector 2, and the connector 2 is connected to a sampling head 3. The inner wall of the sampling head 3 is connected to the first rubber pad 101 and the second rubber pad 111. The front surface of the sampling head 3 is provided with a round hole 4. The inside of the sampling tube 1 is fitted with a piston block 8. The rear surface of the piston block 8 is provided with a needle rod 6. The rear end face of the needle rod 6 is fixedly connected with a push plate 7, and the push plate 7 is fixedly connected with a limiting rod 503.

[0033] The effect achieved by the entire embodiment 4 is as follows: When sampling mycotoxins, the push plate 7 is pushed downward, so that the push plate 7 can drive the needle rod 6 and the piston block 8 to slide inside the sampling tube 1. By moving the piston block 8 downward, the air in the sampling tube 1 can be discharged through the gap at the parallel fit of the first sealing plate 102 and the second sealing plate 112. When the piston block 8 moves to the designated position, the push plate 7 can be pulled upward, so that the sampling tube 1 can extract mycotoxins. After the sampling tube 1 has been extracted, the needle rod 6 can be pulled out from the inside of the sampling tube 1, so that the limiting rod 503 can extend and separate from the inside of the sleeve 502, so that the mycotoxins inside the sampling tube 1 can be poured into the designated place for testing.

[0034] The working principle of the entire device is as follows: the limiting ring 501 is pushed on the outer surface of the sampling tube 1. The movement of the limiting ring 501 can drive the sleeve 502 to move together. The movement of the sleeve 502 allows the limiting rod 503 to slide inside the sleeve 502. After the height of the limiting ring 501 is adjusted, the fastening rod 901 can be inserted through the limiting ring 501 and extended into the outer surface of the sampling tube 1. The friction pad 903 can increase the friction between the fastening rod 901 and the limiting ring 501, so that the fastening rod 901 can fix the limiting ring 501.

[0035] Pushing the push plate 7 downwards allows it to drive the needle rod 6 and piston block 8 to slide inside the sampling tube 1. As the piston block 8 moves downwards, the air inside the sampling tube 1 can be discharged through the gap at the parallel fit between the first sealing plate 102 and the second sealing plate 112. When the piston block 8 moves to the designated position, the push plate 7 can be pulled upwards. The first sealing plate 102 and the second sealing plate 112 are vacuumed from inside the sampling tube 1, allowing them to open. The fungal toxins can then be drawn into the sampling tube 1 through the round hole 4 of the sampling head 3 for sampling. After the sampling tube 1 has been sampled, the needle rod 6 can be pulled out from inside the sampling tube 1, allowing the limiting rod 503 to extend and separate from the sleeve 502. This allows the fungal toxins inside the sampling tube 1 to be poured into a designated location for testing.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
