Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5 The present invention provides the following technical solution: A sampling device for food quality testing includes a sampling cylinder 1, a top cover 6 on the top of the sampling cylinder 1, a cutting mechanism 3 on the bottom of the top cover 6, a bottom cover 4 on the bottom of the sampling cylinder 1, and a support mechanism 9 on the bottom of the sampling cylinder 1. The cutting mechanism 3 includes a pressing block 301, a spring 302, a slide rod 303, and a cutting cylinder 304. The bottom of the pressing block 301 is fixedly connected to the top of the slide rod 303. The slide rod 303 is slidably inserted into the inside of the top cover 6. The spring 302 is movably sleeved on the surface of the slide rod 303. The top of the spring 302 contacts the bottom of the pressing block 301, and the bottom of the spring 302 contacts the top of the top cover 6. The top of the cutting cylinder 304 is fixedly connected to the bottom of the slide rod 303, and a blade is provided at the bottom of the cutting cylinder 304.
[0020] In this embodiment: When sampling vegetable leaves, the anti-slip block 2 of the sampling cylinder 1 is held and the bottom cover 4 is unscrewed. The anti-slip pad 902 is placed on a clean, flat surface to stabilize the sampling cylinder 1. The vegetable leaves are placed on the cutting pad 903, which is treated with food-grade epoxy resin. The anti-slip protrusions 10 of the pressing block 301 are pressed, which drives the sliding rod 303 to compress the spring 302, so that the blade at the bottom of the cutting cylinder 304 cuts the vegetable leaves. The blade is also treated with food-grade epoxy resin to ensure safety. After cutting, the pressing block 301 is released, and the spring 302 rebounds, bringing the vegetable pieces into the sampling cylinder 1 for storage. The rubber block 8 limits the sliding rod 303. The gaps are sealed to prevent bacteria from entering. Then, the bottom cover 4 is tightened to complete the sampling. During testing, the anti-slip block 2 is held and the top cover 6 is unscrewed. The vegetable pieces inside the cutting cylinder 304 can be picked out for pesticide residue and other safety tests. The entire sampling process for vegetable leaves does not require hand contact with the blade and sample, which not only ensures operational safety but also improves sample cleanliness and ensures the accuracy of test results. It solves the problem that some existing food sampling structures, especially when conducting quality testing on vegetable foods, are inconvenient and still require manual cutting with a blade, which is inefficient and prone to sample contamination.
[0021] Specifically, such as Figure 4 As shown, the support mechanism 9 includes a support frame 901, several anti-slip pads 902 and a cutting pad 903. The top of the support frame 901 is fixedly connected to the bottom of the sampling cylinder 1, the top of the anti-slip pads 902 is fixedly connected to the bottom of the support frame 901, and the bottom of the cutting pad 903 is fixedly connected to the surface of the support frame 901.
[0022] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the inner wall of the bottom cover 4 is threadedly connected to the surface of the sampling cylinder 1, and a screw block 5 is fixedly connected to the bottom of the bottom cover 4.
[0023] Specifically, such as Figure 2 As shown, anti-slip blocks 2 are fixedly connected to the surface of the sampling cylinder 1. There are several anti-slip blocks 2, which are evenly distributed on the surface of the sampling cylinder 1.
[0024] In this embodiment: the support mechanism 9 is connected to the sampling cylinder 1 through the support frame 901. The bottom anti-slip pad 902 increases the friction with the plane to prevent the sampling cylinder 1 from sliding and shifting during sampling, ensuring operational stability. The cutting pad 903 is treated with a thin coating of food-grade epoxy resin, which is safe and non-toxic and provides a flat cutting surface. The bottom cover 4 is threadedly connected to the sampling cylinder 1 and is fitted with a hand-held screw block 5, which facilitates quick disassembly and assembly of the bottom cover 4. The anti-slip blocks 2 on the surface of the sampling cylinder 1 are evenly distributed, making it convenient to hold the sampling cylinder 1 by hand and to rotate the bottom cover 4 and the top cover 6.
[0025] Specifically, such as Figure 3As shown, a rubber block 8 is fixedly sleeved on the surface of the slide bar 303, and the top of the rubber block 8 is in contact with the top of the inner wall of the top cover 6.
[0026] Specifically, such as Figure 2 As shown, the top of the pressing block 301 is fixedly connected with anti-slip protrusions 10, and the number of anti-slip protrusions 10 is several and they are evenly distributed on the top of the pressing block 301.
[0027] In this embodiment: the rubber block 8 on the surface of the slide bar 303 contacts the top of the inner wall of the top cover 6, which limits the stroke of the slide bar 303 when the spring 302 rebounds, preventing it from moving too high, and at the same time sealing the gap between the slide bar 303 and the top cover 6 to prevent bacteria from entering and contaminating the sample. The anti-slip protrusions 10 on the top of the pressing block 301 increase the friction when the hand presses, preventing slippage.
[0028] Specifically, such as Figure 2 and Figure 3 As shown, the inner wall of the top cover 6 is threadedly connected to the surface of the sampling cylinder 1, and a rubber anti-slip strip 7 is fixedly connected to the surface of the top cover 6. The number of rubber anti-slip strips 7 is several and they are evenly distributed on the surface of the top cover 6.
[0029] Specifically, such as Figure 3 and Figure 4 As shown, both the cutting cylinder 304 and the cutting pad 903 are treated with a thin coating of food-grade epoxy resin.
[0030] In this embodiment: the top cover 6 is threadedly connected to the sampling cylinder 1 and is provided with a rubber anti-slip strip 7, which facilitates opening and closing. The anti-slip strip increases the friction during rotation, making operation easier. The cutting cylinder 304 and the cutting pad 903 are treated with a thin coating of food-grade epoxy resin, which is chemically stable and does not react with vegetables, thus avoiding contamination of vegetable samples and ensuring sample purity and detection accuracy.
[0031] Working principle: When sampling vegetable leaves, first, by holding the anti-slip block 2 on the surface of the sampling cylinder 1, turn the screw block 5 at the bottom of the bottom cover 4 to unscrew the bottom cover 4 from the bottom of the sampling cylinder 1. At this time, place the anti-slip pad 902 on a clean flat surface. The anti-slip pad 902 increases the friction between the support frame 901 and the flat surface, ensuring the stability of the sampling cylinder 1 during the sampling process. Next, place the vegetable leaf to be sampled flat on top of the cutting pad 903 of the support mechanism 9. The cutting pad 903 is located on the surface of the support frame 901 and is treated with a thin coating of food-grade epoxy resin, which is safe and harmless and provides stability for the cutting process. After support, the operator presses the anti-slip protrusions 10 on the top of the pressing block 301 to increase the friction between the hand and the pressing block 301, making the pressing operation more stable. Under pressure, the pressing block 301 drives the sliding rod 303 to slide downwards inside the top cover 6. Simultaneously, the spring 302 sleeved on the surface of the sliding rod 303 is compressed, causing the cutting cylinder 304, fixedly connected to the bottom of the sliding rod 303, to move downwards. The blade at the bottom of the cutting cylinder 304 contacts and cuts the vegetable leaves. The blade is also treated with a thin coating of food-grade epoxy resin, ensuring no chemical reaction with the vegetables and guaranteeing the safety and purity of the sample. After cutting... The vegetable pieces remain inside the cutting cylinder 304. The operator releases the pressing block 301, causing the compressed spring 302 to rebound, pushing the sliding rod 303 and the cutting cylinder 304 upwards. At this point, the vegetable pieces are drawn into the sampling cylinder 1 for storage. The rubber block 8 limits the sliding rod 303, preventing it from moving excessively upwards. The rubber block 8 also seals the gap between the sliding rod 303 and the top cover 6, preventing bacteria from entering. Finally, the bottom cover 4 is screwed back onto the bottom of the sampling cylinder 1, completing the sampling operation. When the sample needs to be tested back in the laboratory, it can be retrieved by hand again. The anti-slip strip 2 on the surface of the sample cylinder 1 and the rubber anti-slip strip 7 on the surface of the top cover 6 are screwed on to open the top cover 6. The vegetable pieces can be picked out from the inside of the cutting cylinder 304 for safety testing such as pesticide residues. The entire sampling process does not require holding a blade or having your hands in contact with the cut vegetable pieces, which improves safety and sample cleanliness. It solves the problem that some existing food sampling structures, especially when conducting quality testing on vegetable foods, are inconvenient and still require manual cutting with a blade, which is inefficient and prone to sample contamination. In addition, the entire device can be washed and disinfected, making it convenient for reuse.
[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
