Description

Technical Field

[0001] This invention belongs to the technical field of refrigeration equipment, and relates to a categorized storage refrigeration device, particularly an animal sample categorized storage refrigeration device. Background Technology

[0002] When studying animal populations, diets, migrations, and pollution, it is necessary to collect animal feces, hair, feathers, molted skin, eggshells, blood, saliva, and urine for DNA analysis, hormone level determination, and diet analysis. During collection, staff need to carry a refrigerated box to the animal habitat, then refrigerate the collected animal samples, and finally return them to the research center for testing.

[0003] Conventional refrigerated boxes present several challenges in the field collection and preservation of animal samples. For instance, storing different animal samples in the same area can easily lead to cross-contamination. When searching for or retrieving different types of collection boxes or test tubes containing feces, hair, feathers, molted skin, eggshells, blood, saliva, and urine, the need to reach to the bottom of the box increases the opening area and time required. This allows fallen leaves, grass clippings, dust, pollen, and even small insects to easily be blown into the box by the wind, contaminating test tubes, collection boxes, and the inner walls of the box, thus affecting subsequent testing. Furthermore, the batteries and refrigeration units are heavy, making it difficult for staff to carry the refrigerated boxes. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an animal sample classification, storage, and refrigeration device. The technical problem this invention aims to solve is: how to achieve effortless carrying, effectively prevent cross-contamination, reduce the opening area of ​​the box and the time required, and prevent external debris from contaminating test tubes, collection boxes, and the inner wall of the shell, thus affecting subsequent testing.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An animal sample classification and storage refrigeration device includes a box shell with a lid movably attached to the top, characterized in that a power supply component is provided at the bottom of the box shell, and a barrier component and a classification and storage component are arranged from high to low inside the box shell, a non-powered cooling component is provided inside the classification and storage component, and an electric cooling component is provided at one end of the box shell.

[0007] The power supply component includes a battery pack fixed inside the battery protective casing;

[0008] The electric cooling assembly includes a semiconductor refrigeration chip assembly. The power input terminal of the semiconductor refrigeration chip assembly is fixedly connected to a power cord, and the other end of the power cord is plugged into and fixed to a battery pack via a plug. The cooling surface of the semiconductor refrigeration chip assembly is fixedly provided with a cold-conducting plate, and the other side of the cold-conducting plate is fixedly provided with two contact plates. The heating surface of the semiconductor refrigeration chip assembly is fixedly provided with a heat sink.

[0009] The barrier assembly includes two transparent folding plates. A movable rod is fixed to one end of each transparent folding plate, and a fixed rod is fixed to the other end of each transparent folding plate. The fixed rod is fixed to the top of the inner walls on both sides of the housing. A second permanent magnet is fixed to the other end of the movable rod, and a pull rod is fixed to the top of the movable rod. An elastic rope is fixed between the pull rod and the fixed rod. Two first permanent magnets are fixed to the inner walls at both ends of the housing along their vertical centerline. The first permanent magnets and the second permanent magnets are magnetically attracted to each other.

[0010] The classified storage component includes a first refrigerated frame and a second refrigerated frame placed inside the box shell. The first refrigerated frame and the second refrigerated frame are each provided with a contact groove on an adjacent side end. Two through holes are provided at one end of the box shell. The contact plate is slidably connected to the inside of the contact groove through the through holes.

[0011] The working principle of this invention is as follows: After arriving at the animal habitat, the power cord is unplugged, causing the battery protective shell to separate from the semiconductor cooling chip assembly. Then, the heat sink is pulled to cause the contact plate to disengage from the contact groove, causing the electric cooling component to separate from the housing and the power supply component. Then, the housing is moved to detach from the battery protective shell, thus completing the disassembly of the power supply component and the electric cooling component. The housing is then carried to the animal where the sample needs to be collected, thereby enabling the animal sample classification, storage, and refrigeration device to be used. When carrying it, the power supply component and the electric cooling component can be detached, making it easier to carry.

[0012] During collection, open the box lid, then pull the movable rod above the first refrigerated frame to separate the second permanent magnet from the first permanent magnet. At this point, the elastic rope pulls the movable rod closer to the fixed rod, causing the transparent folding plate to fold and retract. This allows you to remove the test tubes inside the first refrigerated frame and collect animal blood, urine, and saliva into the test tubes. After placing the test tubes inside the first refrigerated frame, close the barrier component above the first refrigerated frame and open the barrier component above the second refrigerated frame to collect animal feces, hair, feathers, etc. Solid materials such as molted skin and eggshells are placed into the collection box, which is then placed inside the second refrigeration frame. The barrier component above the second refrigeration frame is then closed, and the box lid is closed before returning with the box. This allows the animal sample classification and storage refrigeration device to collect and store samples in batches. Adaptive sealing of the first and second refrigeration frames effectively prevents fallen leaves, soil, and other field debris from easily falling into the unused or inconspicuous first or second refrigeration frames during the collection process, thus preventing contamination of the collected animal samples.

[0013] The top four corners of the battery protective shell are evenly fixed with four positioning blocks, and the bottom four corners of the shell are evenly opened with four positioning slots. The positioning blocks are movably engaged with the positioning slots. A USB interface and a power cord plug interface are opened on one side of the battery protective shell.

[0014] With the above structure, the moving housing drives the positioning block to insert along the positioning groove, thus completing the connection and installation of the housing and the battery protection shell, thereby facilitating installation. The USB interface and the power cord plug interface can charge the battery pack inside the battery protection shell through multiple methods.

[0015] A cooling fan is fixedly mounted on the other side of the heat sink, and a heat-insulating protective sleeve is fitted and fixed around the outer walls of the semiconductor cooling chip assembly.

[0016] With the above structure, when the semiconductor cooling chip group is powered on, the cold source is transferred to the interior of the classified storage component along the cooling surface, the cold conduction plate and the contact plate, and the heat source is transferred to the interior of the heat sink along the heating surface to complete the heat dissipation. The heat dissipation fan blows away the heat to increase the heat dissipation effect. The heat insulation protective cover facilitates heat preservation and protection of the semiconductor cooling chip group.

[0017] Two elastic bands are fixed at the bottom of the box lid, and the elastic bands have snap-fit ​​holes inside. Two snap-fit ​​blocks are fixed at the top of both sides of the box shell. The elastic bands are movably snapped into the snap-fit ​​blocks through the snap-fit ​​holes. Two connecting plates are fixed at the middle of both sides of the box shell. A rotating frame is rotatably connected inside the connecting plate, and a handle is fixed at the other end of the rotating frame. The two handles are movably snapped into each other through snap-fit ​​components.

[0018] With the above structure, when sealing the case, press the lid and pull the elastic band to make the snap hole and snap block snap together and fix it, thus completing the sealing and increasing the sealing stability of the case. When carrying the case, rotate the rotating frame to fix the two handles together, and then pull the handles to carry the case, increasing portability.

[0019] The top of the inner wall at both ends of the housing has four evenly spaced grooves, and the two moving rods slide inside the four grooves.

[0020] The above structure uses a sliding groove to limit the position of the moving rod, preventing it from shifting downwards due to gravity when the rod is opened.

[0021] The non-powered cooling assembly includes two non-powered cooling frames, each being a hollow frame with a rectangular cross-section. Each non-powered cooling frame has a cold source placement slot inside, and a heat-absorbing material is placed inside the cold source placement slot. One non-powered cooling frame is fixed inside a first refrigeration frame, and the other non-powered cooling frame is fixed inside a second refrigeration frame. The bottom inner wall of the first refrigeration frame has multiple test tube slots, and a fixing frame is fixed to the bottom inner wall of the first refrigeration frame. Multiple test tube rings are fixed to the outside of the fixing frame. A partition frame is fixed to the bottom inner wall of the second refrigeration frame.

[0022] With the above structure, the electric cooling component works to cool the sample, and the heat-absorbing material inside the cold source placement tank absorbs and stores the cold source. After the power supply component and the electric cooling component are separated, the heat-absorbing material can be heated and cooled, ensuring that the collection box inside the partition frame and the test tubes inside the test tube slot and test tube ring reach the required temperature, preventing the collected animal samples from deteriorating due to high temperature during the carrying and transfer process after collection.

[0023] The first and second refrigerated frames are each fixed with a sliding assembly at opposite ends. The sliding assembly includes a fixed plate and a first toothed plate fixed to one end of the first refrigerated frame. A roller assembly is rotatably connected inside the fixed plate, and the rollers of the roller assembly are rotatably connected to the inner wall of the box. The sliding assembly also includes a second toothed plate. A gear is meshed between the second toothed plate and the first toothed plate. A rotating shaft is fixed at one end of the gear and rotates on the inner wall of the box. A limiting groove is opened at the bottom end of the second toothed plate, and a limiting rod slides inside the limiting groove. A partition is fixed to the bottom inner wall of the box. The bottom end of the limiting rod is fixed to the top end of the partition. An L-shaped dividing rod is fixed to the top end of the second toothed plate. An inclined surface is opened at the top end of the side of the second permanent magnet near the first permanent magnet.

[0024] Using the above structure, the roller assembly, fixing plate, and box shell work together to limit the position of the first and second refrigeration frames, reducing the friction when the first and second refrigeration frames move upward. The upward movement of the first and second refrigeration frames causes the first toothed plate to move upward, which in turn causes the gear to rotate. At the same time, the rotation of the gear causes the second toothed plate to move downward, which in turn causes the L-shaped dividing rod to move downward, separating the second permanent magnet and the first permanent magnet. This allows the first and second refrigeration frames to move upward, which in turn causes the corresponding blocking components to open adaptively without the need for manual opening by the staff. This makes the animal sample classification and storage refrigeration device easy to use.

[0025] An air damper is fixed to the top of the fixed plate, and an mounting plate is fixed to the top of the air damper. The mounting plate is fixed to the corresponding position on the inner wall of the housing.

[0026] With the above structure, the air damper absorbs and slows down the moving force on the first and second refrigeration frames at the corresponding positions, thereby ensuring smooth movement.

[0027] It also includes a control component, which includes a battery-driven motor fixed to the inner wall of the bottom end of the housing and two pulleys. A transmission belt is meshed between the two pulleys. One end of one pulley is fixed to the output end of the battery-driven motor. One end of the other pulley is fixed to a round rod, and the other end of the round rod rotates on the inner wall of the housing. The other end of the pulley is fixed to a lead screw, and an internally threaded sleeve is screwed onto the outer cylindrical surface of the lead screw. A connecting frame is fixed to the outer wall of the internally threaded sleeve, and a positioning rod slides inside the connecting frame. The two ends of the positioning rod are fixed to the bottom of the inner walls at both ends of the housing. A second pressing block is fixed to the top of the connecting frame. Both of the two second pressing blocks have inclined surfaces on their adjacent sides. A first pressing block is fixed to the bottom of both the first and second refrigeration frames. Both of the two first pressing blocks have inclined surfaces on their opposing sides. The first pressing block abuts against the second pressing block. Two moving holes are opened inside the partition, and the first pressing block slides inside the moving holes.

[0028] Using the above structure, the battery drives the motor to work and, in conjunction with the pulley and transmission belt, drives the lead screw to rotate. The rotation of the lead screw causes the internal threaded sleeve to move along the lead screw under the limiting state of the connecting frame and the positioning rod. This causes the second extrusion block to extrude or detach from the first extrusion block. By controlling the forward and reverse rotation of the battery-driven motor, the first extrusion block is driven to move upward or remain stationary. This causes the first and second refrigeration frames at the corresponding positions to move upward or remain stationary, making it convenient for staff to pick up and store test tubes or collection boxes during collection.

[0029] The bottom of the enclosure is provided with a battery interface, and the top of the battery protective shell is fixed with a battery plug, which is movably connected to the battery interface. A control panel is fixed on one side of the enclosure, and a temperature sensor is fixed in the middle of the bottom of the enclosure cover. The control panel is electrically connected to the semiconductor cooling chip group, the cooling fan, the temperature sensor and the battery drive motor through a processor controller.

[0030] With the above structure, the electrical energy of the battery pack can be used to charge the battery of the battery drive motor through the battery plug, battery interface and external wires, ensuring the normal operation of the battery drive motor.

[0031] Compared with existing technologies, this animal sample classification, storage, and refrigeration device has the following advantages:

[0032] This invention, by setting up detachable power supply components and electric cooling components, and in conjunction with a dual-cold source structure (electric cooling component and non-powered cooling component), enables the animal sample classification and storage refrigeration device to detach the power supply components and electric cooling components when carrying, making it easier to carry and preventing the animal samples from deteriorating due to high temperatures during the carrying and transfer process after collection.

[0033] This invention utilizes a categorized barrier component and a categorized storage component. An electrically driven mechanism lifts the categorized storage component, which in turn opens the corresponding barrier component. This allows the animal sample categorization and storage refrigeration device to collect and store samples in batches. The first and second refrigeration frames are adaptively sealed, and a transparent folding plate is used to prevent the need to reach to the bottom of the box, which would increase the opening area and time required for searching. This prevents fallen leaves, grass clippings, dust, pollen, and even small insects from being easily blown into the box by the wind, contaminating test tubes, collection boxes, and the inner wall of the shell, thus preventing interference with subsequent testing.

[0048] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0049] like Figures 1-13 As shown, the animal sample classification, storage and refrigeration device includes a box shell 301 with a box cover 304 movably attached to the top. The device is characterized in that a power supply component is provided at the bottom of the box shell 301, and a barrier component and a classification and storage component are provided inside the box shell 301 from high to low. A non-powered cooling component is provided inside the classification and storage component, and an electric cooling component is provided at one end of the box shell 301.

[0050] The power supply components include a battery pack fixed inside the battery protective casing 101;

[0051] The electric cooling assembly includes a semiconductor cooling chip assembly 201. A power cord 102 is fixedly connected to the power input terminal of the semiconductor cooling chip assembly 201, and the other end of the power cord 102 is plugged into and fixed to the battery pack via a plug. A cold-conducting plate 202 is fixedly provided on the cooling surface of the semiconductor cooling chip assembly 201, and two contact plates 203 are fixedly provided on the other side of the cold-conducting plate 202. A heat sink 204 is fixedly provided on the heating surface of the semiconductor cooling chip assembly 201.

[0052] The barrier assembly includes two transparent folding plates 403. A movable rod 401 is fixed at one end of the transparent folding plate 403, and a fixed rod 402 is fixed at the other end of the transparent folding plate 403. The fixed rod 402 is fixed to the top of the inner walls on both sides of the housing 301. A second permanent magnet 406 is fixed at the other end of the movable rod 401, and a pull rod 404 is fixed at the top of the movable rod 401. An elastic rope 405 is fixed between the pull rod 404 and the fixed rod 402. Two first permanent magnets 340 are fixed along the vertical centerline of the inner walls at both ends of the housing 301. The first permanent magnets 340 and the second permanent magnets 406 are magnetically attracted to each other.

[0053] The categorized storage component includes a first refrigerated frame 501 and a second refrigerated frame 502 placed inside the casing 301. Each of the first refrigerated frame 501 and the second refrigerated frame 502 has a contact groove 503 on one side of an adjacent side. One end of the casing 301 has two through holes 302. The contact plate 203 is slidably connected to the inside of the contact groove 503 through the through holes 302.

[0054] Upon arrival at the animal habitat, unplug the power cord 102 to separate the battery protective case 101 from the semiconductor cooling chip assembly 201. Then, pull the heat sink 204 to disengage the contact plate 203 from the contact groove 503, thus separating the electric cooling component from the housing 301 and the power supply component. Then, move the housing 301 to detach it from the battery protective case 101 to complete the disassembly of the power supply component and the electric cooling component. Then, carry the housing 301 to the animal where the sample needs to be collected, thereby enabling the animal sample classification, storage, and refrigeration device to be used. When carrying it, the power supply component and the electric cooling component can be detached, making it easier to carry.

[0055] During collection, open the box lid 304, then pull the movable rod 401 above the first refrigeration frame 501 to separate the second permanent magnet 406 from the first permanent magnet 340. At this time, under the elastic force of the elastic rope 405, pull the movable rod 401 to a position close to the fixed rod 402, causing the transparent folding plate 403 to fold and retract. The test tubes inside the first refrigeration frame 501 can then be removed to collect animal blood, urine, and saliva. After placing the test tubes inside the first refrigeration frame 501, close the barrier component above the first refrigeration frame 501 and open the barrier component above the second refrigeration frame 502 to collect animal samples. Solid materials such as feces, hair, feathers, molted skin, and eggshells are collected into the collection box. The collection box is then placed inside the second refrigeration frame 502, and the barrier component above the second refrigeration frame 502 is closed. Finally, the box lid 304 is closed, and the box shell 301 can be carried back. This allows the animal sample classification and storage refrigeration device to collect and store samples in batches. The first refrigeration frame 501 and the second refrigeration frame 502 are adaptively sealed to effectively prevent fallen leaves, soil, and other impurities from the wild from easily falling into the unused and inconspicuous first refrigeration frame 501 or second refrigeration frame 502 during the collection process, thereby contaminating the collected animal samples.

[0056] Four positioning blocks 104 are evenly fixed at the four corners of the top of the battery protective case 101, and four positioning grooves 310 are evenly opened at the four corners of the bottom of the case 301. The positioning blocks 104 are movably engaged with the positioning grooves 310. A USB interface 105 and a wire plug interface 106 are opened on one side of the battery protective case 101.

[0057] In this embodiment, the movable housing 301 drives the positioning block 104 to be inserted along the positioning groove 310, thereby completing the connection and installation of the housing 301 and the battery protection housing 101, thus facilitating installation. The USB interface 105 and the wire plug interface 106 can charge the battery pack inside the battery protection housing 101 through multiple pathways.

[0058] A cooling fan 205 is fixedly mounted on the other side of the heat sink 204, and a heat insulation protective sleeve 206 is fixedly fitted around the outer wall of the semiconductor cooling chip assembly 201.

[0059] In this embodiment, when the semiconductor cooling chip assembly 201 is powered on, the cold source is transferred to the interior of the classified storage component along the cooling surface, the cold conduction plate 202 and the contact plate 203, and the heat source is transferred to the interior of the heat sink 204 along the heating surface to complete the heat dissipation. The heat dissipation fan 205 blows away the heat to increase the heat dissipation effect. The heat insulation protective sleeve 206 facilitates heat preservation and protection of the semiconductor cooling chip assembly 201.

[0060] Two elastic bands 305 are fixed at the bottom of the lid 304. The elastic bands 305 have snap-fit ​​holes 306 inside. Two snap-fit ​​blocks 330 are fixed at the top of both sides of the shell 301. The elastic bands 305 are movably snapped into the snap-fit ​​blocks 330 through the snap-fit ​​holes 306. Two connecting plates 307 are fixed at the middle of both sides of the shell 301. A rotating frame 308 is rotatably connected inside the connecting plate 307. A handle 309 is fixed at the other end of the rotating frame 308. The two handles 309 are movably snapped into each other through snap-fit ​​components.

[0061] In this embodiment, when sealing the case 301, press the case cover 304 and pull the elastic band 305 to make the snap hole 306 snap and fix with the snap block 330, thus completing the sealing and increasing the sealing stability of the case cover 304. When carrying the case 301, rotate the rotating frame 308 to fix the two handles 309 together, and then pull the handles 309 to carry the case 301, increasing portability.

[0062] Four sliding grooves 360 are evenly provided on the top of the inner walls at both ends of the housing 301, and two moving rods 401 slide inside the four sliding grooves 360.

[0063] In this embodiment, the position of the moving rod 401 is limited by the slide groove 360 ​​to prevent the moving rod 401 from moving downward due to gravity when it is opened.

[0064] The non-powered cooling assembly includes two non-powered cooling frames 504, each being a hollow frame with a rectangular cross-section. A cold source placement slot 505 is provided inside each non-powered cooling frame 504, and heat-absorbing material is placed inside the cold source placement slot 505. One non-powered cooling frame 504 is fixed inside the first refrigeration frame 501, and the other non-powered cooling frame 504 is fixed inside the second refrigeration frame 502. Multiple test tube slots 507 are provided on the inner wall of the bottom end of the first refrigeration frame 501, and a fixing frame 506 is fixed to the inner wall of the bottom end of the first refrigeration frame 501. Multiple test tube rings 508 are fixed to the outside of the fixing frame 506. A partition frame 509 is fixed to the inner wall of the bottom end of the second refrigeration frame 502.

[0065] In this embodiment, the electric cooling component operates to cool the sample. The heat-absorbing material inside the cold source placement slot 505 absorbs and stores the cold source. After the power supply component and the electric cooling component are separated, the heat-absorbing material can be heated and cooled, ensuring that the collection box inside the separator 509 and the test tubes inside the test tube slot 507 and test tube ring 508 reach the required temperature, preventing the collected animal samples from deteriorating due to high temperature during the carrying and transfer process after collection.

[0066] Both the first refrigerated frame 501 and the second refrigerated frame 502 have sliding components fixed at opposite ends. Each sliding component includes a fixed plate 510 and a first toothed plate 515 fixed to one end of the first refrigerated frame 501. A roller assembly 511 is rotatably connected inside the fixed plate 510, and the rollers of the roller assembly 511 are in rolling contact with the inner wall of the housing 301. The sliding component also includes a second toothed plate 518, and a gear 516 meshes between the second toothed plate 518 and the first toothed plate 515. A rotating shaft 517 is fixed at one end of the 6, and the rotating shaft 517 rotates on the inner wall of the housing 301. A limiting groove 519 is opened at the bottom end of the second toothed plate 518, and a limiting rod 350 slides inside the limiting groove 519. A partition 380 is fixed on the bottom inner wall of the housing 301, and the bottom end of the limiting rod 350 is fixed to the top end of the partition 380. An L-shaped dividing rod 520 is fixed at the top end of the second toothed plate 518. An inclined surface is opened on the top end of the side of the second permanent magnet 406 near the first permanent magnet 340.

[0067] In this embodiment, the roller assembly 511, the fixing plate 510, and the housing 301 work together to limit the positions of the first refrigeration frame 501 and the second refrigeration frame 502, reducing the friction when the first refrigeration frame 501 and the second refrigeration frame 502 move upward. The upward movement of the first refrigeration frame 501 and the second refrigeration frame 502 drives the first toothed plate 515 to move upward, thereby causing the gear 516 to rotate. At the same time, the rotation of the gear 516 drives the second toothed plate 518 to move downward. The downward movement of the second toothed plate 518 drives the L-shaped dividing rod 520 to move downward, separating the second permanent magnet 406 and the first permanent magnet 340. This allows the first refrigeration frame 501 and the second refrigeration frame 502 to move upward, which can adaptively open the corresponding blocking components without requiring manual opening by staff. This makes the animal sample classification and storage refrigeration device easy to use.

[0068] An air damper 512 is fixed to the top of the fixed plate 510, and an mounting plate 513 is fixed to the top of the air damper 512. The mounting plate 513 is fixed to the corresponding position on the inner wall of the housing 301.

[0069] In this embodiment, the air damper 512 works to absorb and reduce the moving force on the first refrigerator frame 501 and the second refrigerator frame 502 at the corresponding positions, thereby ensuring their smooth movement.

[0070] It also includes a control assembly, which includes a battery-driven motor 601 fixed to the inner wall of the bottom end of the housing 301 and two pulleys 602. A drive belt 605 is meshed between the two pulleys 602. One end of one pulley 602 is fixedly connected to the output end of the battery-driven motor 601. A round rod 604 is fixedly attached to one end of the other pulley 602, and the other end of the round rod 604 rotates on the inner wall of the housing 301. A lead screw 603 is fixedly attached to the other end of the pulley 602, and an internally threaded sleeve 606 is screwed onto the outer cylindrical surface of the lead screw 603. A connecting bracket 607 is fixedly attached to the outer wall of the internally threaded sleeve 606. Furthermore, a positioning rod 609 slides inside the connecting frame 607, with both ends of the positioning rod 609 fixed to the bottom of the inner walls at both ends of the housing 301. A second pressing block 608 is fixed at the top of the connecting frame 607, and a slope is opened on the side of the two second pressing blocks 608 that are close to each other. A first pressing block 514 is fixed at the bottom of the first refrigeration frame 501 and the second refrigeration frame 502, and a slope is opened on the side of the two first pressing blocks 514 that are opposite to each other. The first pressing block 514 abuts against the second pressing block 608. Two moving holes 370 are opened inside the partition 380, and the first pressing block 514 slides inside the moving holes 370.

[0071] In this embodiment, the battery-driven motor 601 works in conjunction with the pulley 602 and the transmission belt 605 to drive the lead screw 603 to rotate. The rotation of the lead screw 603 drives the internal threaded sleeve 606 to move along the lead screw 603 under the limited state of the connecting frame 607 and the positioning rod 609. This causes the second pressing block 608 to press against or detach from the first pressing block 514. By controlling the forward and reverse rotation of the battery-driven motor 601, the first pressing block 514 is driven to move upward or remain stationary. This causes the first refrigeration frame 501 and the second refrigeration frame 502 at the corresponding positions to move upward or remain stationary, making it convenient for staff to pick up and store test tubes or collection boxes during collection.

[0072] A battery interface 303 is provided at the bottom of the housing 301, and a battery plug 103 is fixed at the top of the battery protective shell 101. The battery plug 103 is movably connected to the battery interface 303. A control panel 320 is fixed on one side of the housing 301, and a temperature sensor is fixed in the middle of the bottom of the cover 304. The control panel 320 is electrically connected to the semiconductor cooling chip group 201, the cooling fan 205, the temperature sensor, and the battery drive motor 601 through the processor controller.

[0073] In this embodiment, the electrical energy of the battery pack can charge the battery of the battery drive motor 601 along the battery plug 103, battery interface 303 and external wires, ensuring that the battery drive motor 601 works normally.

[0074] Working principle of the invention:

[0075] Before collection, unplug the power cord 102 to separate the battery protective case 101 from the semiconductor cooling chip assembly 201. Then pull the heat sink 204 to move the contact plate 203 away from the contact groove 503, so that the electric cooling component is separated from the box 301 and the power supply component. Then move the box 301 to separate it from the battery protective case 101 to complete the disassembly of the power supply component and the electric cooling component. Then pull the handle 309 to carry the box 301 to the animal to be collected.

[0076] During collection, rotating the rotating frame 308 resets the handle 309, then pulling up the elastic band 305 separates the snap-fit ​​hole 306 from the snap-fit ​​block 330. Then, opening the box cover 304 allows the control panel 320 to drive the battery-powered motor 601. The battery-powered motor 601, in conjunction with the pulley 602 and transmission belt 605, drives the lead screw 603 to rotate. This rotation of the lead screw 603 causes the internal threaded sleeve 606 to move forward along the lead screw 603 under the limiting conditions of the connecting frame 607 and the positioning rod 609. This, in turn, causes the second pressing block 608 to press against the first pressing block 514, causing the first pressing block 514 and the first refrigerated frame 501 to move upwards. At this time, the first refrigerated frame 501... The upward movement of 01 causes the first toothed plate 515 to move upward, which in turn causes the gear 516 to rotate. At the same time, the rotation of the gear 516 causes the second toothed plate 518 to move downward. The downward movement of the second toothed plate 518 causes the L-shaped dividing rod 520 to move downward, separating the second permanent magnet 406 and the first permanent magnet 340. At this time, under the elastic force of the elastic rope 405, the moving rod 401 is pulled to move to a position close to the fixed rod 402, thereby causing the transparent folding plate 403 to fold and retract. The test tube inside the first refrigeration frame 501 can then be taken out to collect animal blood, urine, and saliva into the test tube (the same applies when collecting animal samples that need to be placed inside the collection box).

[0077] After collection, place the test tubes inside the test tube slot 507 and test tube ring 508, drive the battery drive motor 601 to reverse so that the second squeezing block 608 is separated from the first squeezing block 514, then press the first refrigeration frame 501 down to reset, close the barrier component, and finally pick up the box cover 304 to seal the box shell 301. The box shell 301 can then be carried back. After returning, the box shell 301, power supply component and electric cooling component can be installed, thus completing the collection, storage and transfer.

[0078] In summary, by setting up detachable power supply and electric cooling components, and in conjunction with a dual-cold source structure, this animal sample classification and storage refrigeration device allows the power supply and electric cooling components to be detached when carried, making it easier to carry.

[0079] By using a classified barrier component and a classified storage component, the classified storage component is lifted by an electric drive, which in turn drives the corresponding barrier component to open. This allows the animal sample classified storage and refrigeration device to collect and store samples in batches. The first refrigeration frame 501 and the second refrigeration frame 502 are adaptively sealed to effectively prevent fallen leaves, soil and other impurities from the field from falling into the unused and inconspicuous first refrigeration frame 501 or second refrigeration frame 502 during the collection process, thus contaminating the collected animal samples. At the same time, it is easy to operate and convenient to handle and store.
