Description

Technical Field

[0001] The utility model relates to the technical field of food microorganism detection, in particular to a sampling device for food microorganism detection. Background Art

[0002] Food microbial testing is a testing method that uses the theories and methods of microbiology to examine the types, quantity, properties of microorganisms in food and their effects on human health, in order to determine whether the food meets quality standards. Food microbial testing is an important and indispensable part of food quality management. It can effectively prevent or reduce the occurrence of food zoonoses and protect people's health. In real life, when conducting microbial testing on some meat foods, sampling is required first. When sampling, first use a cotton swab to dip the meat, and then transfer the sampled cotton swab to the sample placement container for sealing. Since the cotton swab dipped in meat cannot be directly sealed and placed after sampling, the cotton swab may be contaminated during the process of transferring the sampled cotton swab for sealing, which may affect the subsequent test data. Therefore, a sampling device for food microbial testing is proposed to address the above problems. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. A sampling device for food microorganism detection, through the piston plate, piston box, connecting pipe, baffle, sleeve rod, push-pull rod, placement box, slider and cotton swab, when sampling in the process of meat microorganism detection through the device, the piston box and the piston plate are pressed to slide, and gas is further pressed into the sleeve rod through the connecting pipe. At this time, the air pressure in the sleeve rod will increase, and then the fixed block will drive the limit block at the top of the inner rod to move upward, so that the baffle can be pushed open by the push-pull rod, and then the piston box is pushed up, and the cotton swab in the slider is further pushed out of the placement box through the fixed rod. When the cotton swab is removed, the sampling operation can be performed through the cotton swab in the slider when the pressure on the piston box is released. When the sampling is completed, the baffle is opened by pressing the piston box again, and then the piston box is pushed down to collect the cotton swab in the placement box and then the push on the piston box is released, so that the baffle is further blocked at the top inner side of the placement box, and the cotton swab after sampling can be directly transferred to the placement box and sealed. By directly transferring the cotton swab after sampling to the placement box and sealing it, the cotton swab after sampling can be avoided from external contamination to the greatest extent, thereby ensuring the accuracy of subsequent test data.

[0022] Example 2

[0023] like Figure 2-3 As shown, in order to solve the problem of being inconvenient to remove the cotton swab 3 from the slider 2, the outer bottom end of the cotton swab 3 is in contact with a resistance sleeve 4, and the resistance sleeve 4 is fixedly connected to the slider 2. The resistance sleeve 4 is made of rubber. By inserting the cotton swab 3 into the rubber resistance sleeve 4 fixed in the slider 2, it is convenient to remove the cotton swab 3 from the slider 2 later.

[0024] Example 3

[0025] like Figure 2-3 As shown, in order to solve the problem that it is inconvenient to automatically reset the piston box 7 when the pressure on the piston box 7 is released, a spring 8 is fixedly connected to the right end of the piston plate 6, and the other end of the spring 8 is fixedly connected to the piston box 7. When the pressure on the piston box 7 is released, the elastic force of the spring 8 in the compressed state is restored, which facilitates the automatic reset of the piston box 7.

[0026] Example 4

[0027] like Figure 1-3 As shown, in order to solve the problem of inconvenience in positioning the cotton swab 3 that is moved out of the placement box 1, a piston block 9 is slidably connected to the bottom inner end of the slider 2, and a clamping block 10 that penetrates the slider 2 is fixedly connected to the left end of the piston block 9, and the clamping block 10 is slidably connected to the slider 2, and the clamping block 10 is clamped and connected to the placement box 1, and an air pipe 11 is connected to the bottom left end of the piston box 7, and the other end of the air pipe 11 is connected to the slider 2. After pressing and pushing the piston box 7 to make the slider 2 drive the cotton swab 3 to be moved out of the placement box 1, by releasing the pressure on the piston box 7, the gas extracted from the slider 2 is further pressed back into the slider 2 through the air pipe 11, so that the piston block 8 drives the clamping block 10 to be clamped together with the placement box 1 again, which facilitates the positioning of the cotton swab 3 that is moved out of the placement box 1.

[0028] Example 5

[0029] like Figure 1-4As shown, in order to solve the problem that it is inconvenient to open the baffle 18 during the sampling operation, the top of the piston box 7 is connected to a connecting pipe 12, and the other end of the connecting pipe 12 is connected to a sleeve rod 13 fixedly connected to the placement box 1, and a fixed block 14 is slidably connected to the inner side of the sleeve rod 13, and the top of the fixed block 14 is fixedly connected to an inner rod 15 that penetrates the sleeve rod 13, and the top of the inner rod 15 is fixedly connected to a limit block 16 that is slidably connected to the placement box 1, and the right end of the limit block 16 is rotatably connected to a push-pull rod 17 through a rotating shaft, and the other end of the push-pull rod 17 is rotatably connected to the baffle 18 through the rotating shaft. When the sampling operation is performed, by pressing the piston box 7, gas is further pressed into the sleeve rod 13 through the connecting pipe 12, so that the fixed block 14 drives the limit block 16 at the top of the inner rod 15 to move upward, which facilitates pushing the baffle 18 open by the push-pull rod 17.

[0030] In this embodiment, when sampling during the meat microorganism detection process is performed through the device, the piston box 7 is pressed to compress the spring 8 and slide with the piston plate 6, and gas is further pressed into the sleeve rod 13 through the connecting pipe 12, and the gas at the bottom inner side of the slider 2 is extracted through the air pipe 11. At this time, the air pressure in the sleeve rod 13 will increase, and then the fixed block 14 will drive the limit block 16 at the top of the inner rod 15 to move upward, and further push the baffle 18 through the push-pull rod 17. At the same time, the piston block 9 will also drive the card block 10 to slide to the right, further disengaging the card block 10 from the placement box 1, and then push the piston box 7 upward, and further push the cotton swab 3 in the slider 2 out of the placement box 1 through the fixed rod 5. After the piston box 7 can no longer be pushed, the pressure on the piston box 7 is released. At this time, the baffle 18 will contact with the cotton swab 3 during the resetting process, and the card block 10 will contact with the cotton swab 3 during the resetting process. The placement box 1 is stuck together, thereby realizing the positioning of the cotton swab 3 pushed out of the placement box 1. After completing the above operations, the cotton swab 3 in the slider 2 is used to dip the meat for sampling. When the sampling is completed, the baffle 18 is opened by pressing the piston box 7 again, and the card block 10 is disengaged from the placement box 1, and then the piston box 7 is pushed downward, further driving the cotton swab 3 in the slider 2 to move downward, and the sampled cotton swab 3 can be directly transferred to the placement box 1. Then, after the cotton swab 3 is transferred to the placement box 1, the pressing on the piston box 7 is released again to make the card block 10 stuck together with the placement box 1 again, and the baffle 18 is reset to block the top inner side of the placement box 1, so that the sampled cotton swab 3 is directly sealed and placed when the sampling operation is completed, so as to avoid the cotton swab 3 after sampling from being contaminated by the outside to the greatest extent, and ensure the accuracy of subsequent detection data.
