The temperature sensor monitors the temperature inside the cooling chamber and the heating chamber in real time.

[0015] Preferably, the sample storage component includes a sample storage box, with a frustum-shaped insert rod fixedly connected to the four corners of the bottom surface of the sample storage box.

[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0043] Example 1: As Figure 1-7 As shown, this embodiment provides a food testing sample storage box, including an insulated box 100, a sealing cover 101 rotatably connected to the top surface of the insulated box 100, a partition plate 102 fixed inside the insulated box 100, two support blocks 103 fixed on the partition plate 102 in a symmetrical structure, a plurality of through holes 104 opened on the support blocks 103, a cooling chamber 200 and a heating chamber 300 are separated inside the insulated box 100 by the partition plate 102, and a sample storage component 400 is installed on the top surface of the support blocks 103;

[0044] A semiconductor cooling chip 105 is installed at the lower end of the partition plate 102. The cold end of the semiconductor cooling chip 105 abuts against a metal cooling block 106, and the hot end of the semiconductor cooling chip 105 abuts against a radiator 107. Multiple adjustment components 500 are connected to the heat preservation box 100.

[0045] The adjustment assembly 500 includes an intake pipe 501 and an exhaust pipe 502. The intake pipe 501 and the exhaust pipe 502 are respectively provided with slots 503. A movable sealing block 504 is inserted into the slot 503. An electric cylinder 506 is installed inside the intake pipe 501 and the exhaust pipe 502 respectively. One end of the piston rod of the electric cylinder 506 is fixedly connected to the movable sealing block 504.

[0046] The outer peripheral wall of the piston rod of the electric cylinder 506 is slidably connected to the corresponding intake pipe 501 and exhaust pipe 502. An L-shaped block 505 is fixedly installed on the electric cylinder 506, and the L-shaped block 505 is fixedly connected to the inner wall of the corresponding intake pipe 501 and exhaust pipe 502. The electric cylinder 506 is stably installed on the inner wall of the intake pipe 501 and exhaust pipe 502 through the L-shaped block 505. Its piston rod drives the movable sealing block 504 to slide in the pipe, thereby realizing the opening and closing control of the intake pipe 501 and exhaust pipe 502.

[0047] Two air inlet pipes 501 and two exhaust pipes 502 are provided. The two air inlet pipes 501 are installed at the rear end of the insulated box 100, and a filter screen 507 is inserted inside the air inlet pipe 501. The two exhaust pipes 502 are installed at the front end of the insulated box 100, and an exhaust fan 508 is installed inside the exhaust pipe 502. The filter screen 507 reduces the entry of external pollutants into the insulated box 100 and contaminates the samples, providing a cleaner and safer storage environment for food testing samples.

[0048] The bottom surface of the refrigeration chamber 200 is inclined. The front end of the refrigeration chamber 200 is connected to a drain pipe 201 with a valve. The outer peripheral wall of the drain pipe 201 is fixedly connected to the insulation box 100. Two temperature sensors 700 are installed on the upper part of the inner wall of the insulation box 100. The condensate will flow along the inclined bottom surface to the drain pipe 201 at the front end of the refrigeration chamber 200 and be discharged through the drain pipe 201. The temperature sensors 700 monitor the temperature inside the refrigeration chamber 200 and the heating chamber 300 in real time.

[0049] Working principle: When the semiconductor cooling chip 105 is energized, its cold end cools the air in the cooling chamber 200 through the metal cooling block 106, forming a low-temperature environment for storing fresh food samples; at the same time, the hot end transfers heat to the heating chamber 300 through the radiator 107, forming a dry environment suitable for storing dry goods samples; the insulated box 100 physically isolates the cooling chamber 200 and the heating chamber 300 through the partition plate 102 to prevent the cold and hot air from interfering with each other;

[0050] The adjustment component 500 controls the movement of the movable sealing block 504 via the electric cylinder 506 to open and close the intake pipe 501 and exhaust pipe 502. When temperature adjustment is required, the intake pipe 501 and exhaust pipe 502 of the corresponding area are opened to form airflow circulation. For example, when the temperature of the cooling chamber 200 is too high, the intake pipe 501 and exhaust pipe 502 corresponding to the cooling chamber 200 are closed, and the temperature is continuously reduced by the cold end of the semiconductor cooling chip 105. When the temperature of the heating chamber 300 is too low, the corresponding intake pipe 501 and exhaust pipe 502 of the heating chamber 300 are closed. The air inlet pipe 501 and the exhaust pipe 502 utilize the hot end of the semiconductor cooling chip 105 to dissipate heat and raise the temperature. When the temperature is too high, opening the corresponding air inlet pipe 501 and exhaust pipe 502 in the heating chamber 300 to form ventilation can complete the cooling. After placing the sample inside the sample storage component 400, it is placed inside the cooling chamber 200 or the heating chamber 300 at a suitable temperature, which facilitates the maintenance of the storage environment, is beneficial for the preservation of samples of different foods, reduces sample deterioration caused by unsuitable temperature, and improves the accuracy of the test results.

[0051] During temperature regulation, the electric cylinder 506 is securely installed on the inner wall of the intake pipe 501 and the exhaust pipe 502 via the L-shaped block 505. Its piston rod drives the movable sealing block 504 to slide inside the pipe, thereby controlling the opening and closing of the intake pipe 501 and the exhaust pipe 502. When the refrigeration chamber 200 or the heating chamber 300 needs to adjust the temperature, the two intake pipes 501 open, allowing outside air to pass through the filter screen 507 inside the intake pipe 501 to filter out dust, impurities, and other pollutants before entering the corresponding cavity inside the insulation box 100. The exhaust pipe 502, under the action of the exhaust fan 508, discharges the air from the cavity, thus achieving temperature regulation. The filter screen 507 reduces the entry of external pollutants into the insulation box 100 and contaminates the samples, providing a cleaner and safer storage environment for food testing samples.

[0052] The bottom surface of the refrigeration chamber 200 is designed with an inclined structure. When condensation is generated during the refrigeration process, the condensation will flow along the inclined bottom surface to the drain pipe 201 at the front end of the refrigeration chamber 200 under the action of gravity, and the condensation will be discharged through the drain pipe 201. Two temperature sensors 700 on the upper part of the inner wall of the insulation box 100 monitor the temperature in the refrigeration chamber 200 and the heating chamber 300 in real time, so as to control the electric cylinder 506 to adjust the opening and closing of the air inlet pipe 501 and the exhaust pipe 502 in a timely manner, ensuring that the temperature inside the chamber is stable within a suitable range, thus improving the efficiency and accuracy of temperature regulation.

[0053] Example 2: Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, based on Embodiment 1, the sample storage component 400 includes a sample storage box 401. A frustum-shaped insert rod 402 is fixedly connected to the four corners of the bottom surface of the sample storage box 401. The frustum-shaped insert rod 402 is inserted into the through hole 104. A gap is left between the bottom surface of the sample storage box 401 and the support block 103. Hot and cold air can circulate freely around the sample storage box 401 to achieve temperature control of the sample and ensure the temperature regulation effect.

[0054] The top surface of the sample storage box 401 abuts against a cover plate 403. Fasteners 404 are inserted into the four corners of the cover plate 403, and the threaded ends of the fasteners 404 are threadedly connected to the upper end of the sample storage box 401. The cover plate 403 covers the top surface of the sample storage box 401, and the fasteners 404 are used to thread-connect and fix the cover plate 403 to the sample storage box 401 to ensure that the sample is sealed and preserved.

[0055] The sealing cover 101 is fixedly connected to the insulated box 100 by a buckle 600. The bottom surface of the sealing cover 101 abuts against the top surface of the cover plate 403. A limiting groove 405 is provided on the top surface of the sealing cover 101. A connecting rod 406 is provided inside the limiting groove 405. A pin 407 is fixed at one end of the connecting rod 406. The outer peripheral walls of both ends of the pin 407 are rotatably connected to the cover plate 403. The connecting rod 406 and the pin 407 enable the cover plate 403 to rotate around the pin 407 as an axis during opening and closing, which facilitates the retrieval and placement of the sample storage box 401.

[0056] Multiple T-shaped blocks 408 are fixedly provided on the inner wall of the sample storage box 401. An adjusting block 409 is provided between two corresponding T-shaped blocks 408. T-shaped holes 410 are respectively opened at both ends of the adjusting block 409. The T-shaped holes 410 are inserted and engaged with the T-shaped blocks 408. The adjusting block 409 is slidably inserted into the T-shaped blocks 408 on the inner wall of the sample storage box 401 through the T-shaped holes 410 at both ends, thereby changing the position of the adjusting block 409 in the sample storage box 401 and thus flexibly adjusting the size of the sample storage space.

[0057] When storing samples, the samples are placed inside the sample storage box 401, and the top surface of the sample storage box 401 is covered by the cover plate 403. The cover plate 403 is then threadedly connected to the sample storage box 401 using fasteners 404 to ensure that the samples are sealed and preserved. Subsequently, the sample storage box 401 is inserted into the through holes 104 on the support block 103 using the frustum-shaped inserts 402 at the four corners of the bottom surface of the sample storage box 401. Since there is a gap between the bottom surface of the sample storage box 401 and the support block 103, hot and cold air can circulate freely around the sample storage box 401, thereby achieving temperature control of the samples and ensuring the temperature regulation effect.

[0058] When the sealing cover 101 is closed, the bottom surface of the sealing cover 101 abuts against the top surface of the cover plate 403, and the sealing cover 101 is fixedly connected to the insulated box 100 by the buckle 600, which further enhances the sealing performance of the sample storage box 401, helps to maintain the original characteristics of the sample, and improves the accuracy of the test results; the connecting rod 406 and the pin 407 in the limiting groove 405 allow the cover plate 403 to rotate around the pin 407 as the axis during the opening and closing process, which facilitates the taking and putting in of the sample storage box 401;

[0059] If it is necessary to adjust the internal space of the sample storage box 401 to accommodate samples of different sizes, the adjustment block 409 can be slidably inserted into the T-shaped block 408 on the inner wall of the sample storage box 401 through the T-shaped holes 410 at both ends, thereby changing the position of the adjustment block 409 in the sample storage box 401, thus flexibly adjusting the size of the sample storage space and improving the adaptability of the sample storage box 401 to samples of different specifications.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
