[0003] When extracting and detecting food, the food sample needs to be extracted by extraction equipment, and after extraction, the extracted sample needs to be classified and stored to ensure the accuracy of the data after the extraction sample is detected. The existing extraction equipment storage device relies on test tubes to store samples, and then places them on a detection instrument for testing. Through multiple extraction and comparison, the advantages and disadvantages of the sample can be seen.

[0004] Daily food detection can ensure food safety. The objects of food safety detection include raw materials, semi-finished products, various additives, auxiliary materials and products, etc. The types of detection are various, the components are complex, and the types of detection methods are various. The detection items include routine physicochemical items, nutritional components, pesticide residues, food additives and non-food substances, food toxic substances, microorganisms, genetically modified products, etc. The detection items of microorganisms include non-pathogenic bacteria such as total bacterial count, Escherichia coli, coliform bacteria, lactic acid bacteria, and yeast; foodborne pathogenic bacteria such as Escherichia coli, Salmonella, Staphylococcus aureus, hemolytic streptococcus, and mononuclear cell proliferation Listeria. The above microorganisms can be transmitted by contact or carried by air. Food safety detection must be sampled, and if the sample is contaminated during sampling, the detection will be invalid, which will have a great impact.

[0005] A food detection sampling device is disclosed in Chinese Patent No. CN113933109B. A food detection sampling device relates to a food detection sampling device. To solve the problem that liquid food or raw materials are easily contaminated during food detection sampling. The food detection sampling device is composed of a control room and several sampling mechanisms. The present application can realize sterilization, drying, opening of the container, extraction of the liquid, sealing of the sampling tube of the storage container before sampling, and the whole sampling process can avoid sample contamination, remove possible microbial contamination sources, and ensure the accuracy or reliability of food detection.

[0026] The sealing cover is fixedly connected to the back of the storage box and is connected to the extrusion tube. The first limiting sleeve is fixedly connected to the lower part of the inner wall of the storage box, and the other side of the clamp is provided with anti-slip texture.

[0027] An extraction device and method for food testing, comprising the following steps:

[0028] S1. When it is necessary to store the sample, the sample tube should be placed in the storage box and the storage box should be fixed by the clamps inside the storage box to complete the storage.

[0029] S2. When storing samples and sample tubes, the electric push rod needs to be activated through the control panel to push the storage box upward. At this time, the storage box will contact and press the first cover plate through the push block at the rear. Since the first cover plate is connected to the protective shell through the first pin, the first cover plate will gradually flip along the first pin. When the storage box is fully extended inside the protective shell, the first cover plate will be in a 90-degree vertical position. At this time, the storage box can be opened by pulling the handle to store the sample tubes to be stored. Then, the sample information can be placed in the information insert.

[0030] S3. When the handle is pulled to flip the second cover, the second cover will pull the connecting rod through the first hinge and the second hinge during the flipping process. This causes the connecting rod to move upward and the sealing plate to move upward through the second hinge. As the sealing plate moves upward, it will seal the lower movable groove and the upper movable groove will be sealed by the accordion cloth. At the same time, when exchanging gas, the one-way valve can effectively prevent gas leakage in the storage box.

[0031] S4. When the second cover plate flips over, it pulls one end of the squeezing tube, causing the squeezing tube to gradually extend while drawing out the gas from the sealing cover and the second conduit. This allows the gas inside the second conduit to escape while drawing out the gas from the eight telescopic tubes, causing the telescopic tubes to contract rapidly and loosen their grip on the test tube. After the test tube is placed in, simply close the second cover plate, and the sealing plate will reset. The eight clamps will then contact and fix the sample test tube under the pressure of the telescopic tubes.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. The extraction equipment and method for food testing, by setting up a protective shell, cover plate assembly, control panel and push block, requires the control panel to activate the electric push rod when storing samples and sample tubes. The electric push rod pushes the storage box upward, and the first cover plate will gradually flip along the first pin shaft. When the storage box is fully extended from the protective shell, the storage box can be opened by pulling the handle to store the required sample tubes. Then, the sample information can be placed in the information insert. This allows the device to effectively classify and store the stored samples, avoiding the impact of test tube breakage or leakage on other stored samples during storage, and ensuring the safety of the device when storing samples.

[0034] 2. The extraction equipment and method for food testing, by setting up a sealing component, a protective component, and a one-way valve, ensures the internal sealing of the device by setting up a sealing plate that seals the lower movable groove when it moves upward, and the upper movable groove is sealed by a bellows cloth. At the same time, during gas exchange, the one-way valve can effectively prevent gas leakage in the storage tank, thereby ensuring the internal sealing of the device and preventing gas leakage. In addition, it can promptly prevent the spread of bacteria when the test tube is damaged, and can avoid the continuous injection of cooling gas due to gas leakage, thus improving the safety and environmental protection of the device.

[0035] 3. The extraction equipment and method for food testing, by setting up a clamping assembly, a second cover plate, and a storage box, allows the second cover plate to pull one end of the squeezing tube when it flips, causing the squeezing tube to gradually extend while simultaneously drawing gas from the sealing cover and the second conduit. This allows gas to escape from the second conduit while simultaneously drawing gas from the eight telescopic tubes, causing the telescopic tubes to contract rapidly and thus loosen the clamping of the test tube. After the test tube is placed in, simply closing the second cover plate resets the sealing plate, and the eight clamping plates will contact and fix the sample test tube under the pressure of the telescopic tubes. This allows the device to achieve the effect of loosening the test tube clamping when the second cover plate is opened and fixing the test tube when the second cover plate is closed. It can also fix test tubes of different sizes, reducing the difficulty of using the device and improving its automation level. Attached Figure Description

[0049] Example 1

[0050] like Figures 1-3 and Figure 6 As shown, the present invention provides a technical solution: an extraction device and method for food testing, comprising,

[0051] The protective mechanism 100 includes a protective housing 101, a cover assembly 102 disposed above the protective housing 101, a control panel 103, an information insert 105, and a cooling assembly 106, wherein the cooling assembly 106 is disposed behind the protective housing 101, the control panel 103 is disposed in front of the protective housing 101, and the information insert 105 is disposed on the protective housing 101; and,

[0052] The storage mechanism 200 includes a storage box 201, a sealing component 202 disposed above the storage box 201, a protective component 203 disposed inside the storage box 201, a limiting slide 204, a movable groove 205, and a gusseted cloth 206, wherein the gusseted cloth 206 is fixedly connected to the movable groove 205, and the limiting slide 204 is disposed on the back of the storage box 201.

[0053] Furthermore: the upper part of the protective housing 101 is fixedly connected to the lower part of the four cover plate assemblies 102. The front of the protective housing 101 is provided with four observation windows 104, and each of the four observation windows 104 is provided with transparent glass. The front of the four observation windows 104 is fixedly connected to the back of the four control panels 103 respectively. The upper part of the protective housing 101 is fixedly connected with four information inserts 105, and the positions of the four information inserts 105 correspond to the positions of the four observation windows 104 respectively. The back of the protective housing 101 is fixedly connected to the front of the cooling assembly 106. The cooling assembly 106 is connected to the four partitions inside the protective housing 101 through the first conduit 107 respectively. The lower part of the inner wall of the protective housing 101 is fixedly connected with four electric push rods 108. The lower part of the inner wall of the protective housing 101 is fixedly connected with several auxiliary brackets 109. The control panel 103 is electrically connected to the four electric push rods 108 and the cooling assembly 106 respectively through signals.

[0054] Because of the one-way valve 2010, the gas in the storage box 201 is difficult to enter the protective shell 101, thereby avoiding gas exchange or bacterial cross-infection among the multiple storage boxes 201 in the protective shell 101, and ensuring the safety of the device during use.

[0055] The cover assembly 102 includes a first cover 102a, with an adsorption block 102b fixedly connected to the lower part of the first cover 102a. Two first pins 102c are fixedly connected to one side of the first cover 102a. The first cover 102a is hinged to the upper part of the protective shell 101 via the two first pins 102c. Both first pins 102c are fixedly connected to the upper part of the protective shell 101. There are four storage boxes 201, and the upper parts of the four storage boxes 201 are respectively connected to four sealing assemblies 20. 2. Fixed connection: The lower part of the sealing component 202 is fixedly connected to the protective component 203. There are two limiting slide grooves 204, and both limiting slide grooves 204 are opened on the back of the storage box 201. The protective component 203 is slidably connected in the limiting slide groove 204. The first cover plate 102a is mutually attracted to the sealing component 202 through the adsorption block 102b. The four storage boxes 201 are all set in the protective shell 101. The four storage boxes 201 are respectively fixedly connected to the top of the four electric push rods 108.

[0056] In this embodiment, by setting up a protective shell 101, a cover assembly 102, a control panel 103, and a pusher block 209, when storing samples and sample tubes, the electric pusher rod 108 needs to be activated via the control panel 103 to push the storage box 201 upward. At this time, the storage box 201 will contact and press the first cover plate 102a via the pusher block 209. Since the first cover plate 102a is connected to the protective shell 101 via the first pin 102c, the first cover plate 102a will move along the first pin 102c. As the device gradually flips over, when the storage box 201 is fully extended from the protective shell 101, the first cover 102a will be in a 90-degree vertical position. At this time, the storage box 201 can be opened by pulling the handle 202b to store the sample tubes to be stored. Then, the sample information can be placed in the information insert 105. This allows the device to effectively classify and store the stored samples, avoiding the impact of test tube breakage or leakage on other stored samples during the storage process, thus ensuring the safety of the device when storing samples.

[0057] Example 2

[0058] Combined with appendix Figure 2 and attached Figure 4 It is concluded that: there are two movable slots 205, and both movable slots 205 are located on the back of the storage box 201. A gusseted cloth 206 is fixedly connected to the upper part of the inner wall of each movable slot 205, and the gusseted cloth 206 is snapped into the movable slot 205. The lower part of the sealing component 202 is fixedly connected to the extrusion tube 207, and the other end of the extrusion tube 207 is fixedly connected to the storage box 201. A clamping component 208 is fixedly connected to the back of the storage box 201, and the clamping component 208 communicates with the extrusion tube 207 through the storage box 201. The extrusion tube 207 is arc-shaped, and the other end of the clamping component 208... One side is fixedly connected to the lower part of the inner wall of the storage box 201. A push block 209 is fixedly connected to the back of the storage box 201. A one-way valve 2010 is provided on the back of the storage box 201. The sealing assembly 202 includes a second cover plate 202a. A handle 202b is fixedly connected to the upper part of the second cover plate 202a. A magnetic block 202c is provided outside the handle 202b. A second pin 202d is fixedly connected to the lower part of the second cover plate 202a. The second cover plate 202a is hinged to the upper part of the storage box 201 through the second pin 202d. The magnetic block 202c and the adsorption block 102b are attracted to each other.

[0059] When the second cover plate 202a is opened, the sealing plate 203e moves upward, which seals the one-way valve 2010 and the movable groove 205, making it difficult for the gas inside the protective shell 101 to enter the storage box 201, thereby reducing the leakage of low-temperature gas and improving the energy-saving effect of the device.

[0060] The protective assembly 203 includes two first hinges 203a, and each of the two first hinges 203a is fixedly connected to a connecting rod 203b. The other end of the connecting rod 203b is fixedly connected to a second hinge 203c. A fixing block 203d is fixedly connected to the outside of the second hinge 203c. The back of the fixing block 203d is fixedly connected to a sealing plate 203e. A limit slider 203f is provided on the front of the sealing plate 203e. The top of the first hinge 203a is fixedly connected to a second cover plate 202a. The second hinge 203c and the fixing block 203d are slidably connected in the movable groove 205. The top of the fixing block 203d is fixedly connected to the bottom of the accordion fabric 206. The limit slider 203f is slidably connected in the limit groove 204. The clamping assembly 208 includes a sealing cover 208a. One side of the sealing cover 208a is connected to two second conduits 208b. The two second conduits 208b are connected, and the other ends of the two second conduits 208b are connected to the same first limiting sleeve 208c. Several connecting pipes 208d are provided above the first limiting sleeve 208c. The first limiting sleeve 208c is connected to the second limiting sleeve 208e through several connecting pipes 208d. Four telescopic pipes 208f are fixedly connected inside the first limiting sleeve 208c and the second limiting sleeve 208e. The eight telescopic pipes 208f are respectively connected to the first limiting sleeve 208c and the second limiting sleeve 208e. The other ends of the eight telescopic pipes 208f are fixedly connected to clamps 208g. The sealing cover 208a is fixedly connected to the back of the storage box 201. The sealing cover 208a is connected to the extrusion pipe 207. The first limiting sleeve 208c is fixedly connected to the lower part of the inner wall of the storage box 201. The other side of the clamps 208g is provided with anti-slip texture.

[0061] In this embodiment: by setting a sealing component 202, a protective component 203, and a one-way valve 2010, when the handle 202b is pulled to flip the second cover plate 202a, the second cover plate 202a will pull the connecting rod 203b through the first hinge 203a and the second hinge 203c during the flipping process. This causes the connecting rod 203b to move upward, and at the same time, it drives the sealing plate 203e to move upward through the second hinge 203c. Since the sealing plate 203e will seal the lower movable groove 205 when it moves upward, and the upper movable groove 205 will be sealed by the accordion cloth 206, and at the same time, when exchanging gas, the one-way valve 2010 can effectively prevent gas leakage in the storage box 201, thereby ensuring the internal sealing of the device and preventing gas leakage. At the same time, it can promptly block the spread of bacteria when the test tube is damaged, and can avoid the continuous injection of cooling gas due to gas leakage, thus improving the environmental protection effect of the device.

[0062] Example 3

[0063] Combined with appendix Figure 5 and attached Figure 6 Therefore, we can conclude that:

[0064] An extraction device and method for food testing, comprising the following steps:

[0065] S1. When it is necessary to store the sample, the sample tube should be placed in the storage box 201 and the storage box 201 should be fixed by the clamp 208g inside the storage box 201 to complete the storage.

[0066] S2. When storing samples and sample tubes, the electric push rod 108 needs to be activated through the control panel 103 to push the storage box 201 upward. At this time, the storage box 201 will contact and press the first cover plate 102a through the push block 209 at the rear. Since the first cover plate 102a is connected to the protective shell 101 through the first pin 102c, the first cover plate 102a will gradually rotate along the first pin 102c. When the storage box 201 is fully extended from the protective shell 101, the first cover plate 102a will be in a 90-degree vertical position. At this time, the storage box 201 can be opened by pulling the handle 202b to store the sample tubes to be stored. Then, the sample information can be placed in the information insert plate 105.

[0067] S3. When the handle 202b is pulled to flip the second cover 202a, the second cover 202a will pull the connecting rod 203b through the first hinge 203a and the second hinge 203c during the flipping process. This causes the connecting rod 203b to move upward and drive the sealing plate 203e to move upward through the second hinge 203c. As the sealing plate 203e moves upward, it will seal the lower movable groove 205, and the upper movable groove 205 will be sealed by the accordion cloth 206. At the same time, when exchanging gas, the one-way valve 2010 can effectively prevent gas leakage in the storage box 201.

[0068] S4. When the second cover plate 202a flips, it pulls one end of the squeezing tube 207, causing the squeezing tube 207 to gradually extend while simultaneously drawing gas from the sealing cover 208a and the second conduit 208b. This allows gas to escape from the second conduit 208b and draws gas from the eight telescopic tubes 208f, causing the telescopic tubes 208f to contract rapidly, thus loosening the clamp on the test tube. After the test tube is placed in, simply closing the second cover plate 202a resets the sealing plate 203e, and the eight clamping plates 208g will contact and fix the sample test tube under the pressure of the telescopic tubes 208f. This allows the device to achieve the effect of loosening the test tube clamp by opening the second cover plate 202a and fixing the test tube by closing the second cover plate 202a. It can also fix test tubes of different sizes, reducing the difficulty of using the device and improving its automation level.

10. The method of using the extraction device for food testing as described in claim 9, characterized in that, The following usage steps are included: S1. When it is necessary to store the sample, the sample tube should be placed in the storage box (201) and the storage box (201) should be fixed by the clamp (208g) inside the storage box (201) to complete the storage. S2. When storing samples and sample tubes, the electric push rod (108) needs to be activated through the control panel (103) to push the storage box (201) upward. At this time, the storage box (201) will contact and squeeze the first cover plate (102a) through the push block (209) at the rear. Since the first cover plate (102a) is connected to the protective shell (101) through the first pin (102c), the first cover plate (102a) will gradually flip along the first pin (102c). When the storage box (201) is fully extended inside the protective shell (101), the first cover plate (102a) will be in a 90-degree vertical position. At this time, the storage box (201) can be opened by pulling the handle (202b) and the sample tubes to be stored can be stored. Then, the sample information can be put into the information insert (105). S3. When the handle (202b) is pulled to flip the second cover (202a), the second cover (202a) will pull the connecting rod (203b) through the first hinge (203a) and the second hinge (203c) during the flipping process. This causes the connecting rod (203b) to move upward and drive the sealing plate (203e) to move upward through the second hinge (203c). As the sealing plate (203e) moves upward, it will seal the lower movable groove (205) and the upper movable groove (205) will be sealed by the accordion cloth (206). At the same time, when exchanging gas, the one-way valve (2010) can effectively prevent gas leakage in the storage box (201). S4. When the second cover plate (202a) is flipped, the second cover plate (202a) will pull one end of the squeezing tube (207), causing the squeezing tube (207) to gradually extend while drawing gas from the sealing cover (208a) and the second conduit (208b). This causes the gas inside the second conduit (208b) to escape while drawing gas from the eight telescopic tubes (208f), causing the telescopic tubes (208f) to contract rapidly, thereby loosening the clamp on the test tube. After the test tube is placed in, simply close the second cover plate (202a), and the sealing plate (203e) will reset. The eight clamps (208g) will then contact and fix the sample test tube under the compression of the telescopic tubes (208f).
