Description

Technical Field

[0001] This invention relates to the field of monitoring box technology, specifically to a monitoring box for agricultural product transportation that can monitor temperature and humidity without electricity. Background Technology

[0002] Agricultural product transportation monitoring boxes are devices used to monitor and record environmental conditions of agricultural products during transportation. These monitoring boxes typically have temperature and humidity monitoring functions, which can monitor and record the temperature and humidity data inside the box in real time. This data is crucial for ensuring the quality and safety of agricultural products, because suitable temperature and humidity conditions play a decisive role in maintaining the freshness of agricultural products and preventing problems such as mold and rot.

[0003] Traditional monitoring boxes are subject to bumps and vibrations during transportation, leading to unstable power connections and affecting the power supply. When transporting long distances or for extended periods, the monitoring boxes need to operate continuously to maintain the freshness of agricultural products. Prolonged operation consumes a significant amount of electricity. Therefore, when the backup power supply is insufficient, resulting in power loss and equipment malfunction, the monitoring system cannot continue monitoring the transportation environment of agricultural products, such as key parameters like temperature and humidity. Furthermore, increased temperature and humidity can cause agricultural products to spoil, mold, or rot. Without power, the monitoring box cannot effectively alert outsiders to rising temperatures and humidity.

[0004] For transporting certain special fruits and vegetables, such as apples, pears, citrus fruits, tomatoes, and cucumbers, ventilation holes are required in the monitoring box to allow the produce to breathe. Adequate air circulation is necessary to maintain freshness and prevent spoilage. If the monitoring box loses power, it cannot continue monitoring the transport environment of the produce. Once spoiled and rotten produce is left unattended, the ventilation holes prevent timely control of pathogens and pests. Furthermore, the rotting process releases ethylene gas, a plant hormone that promotes fruit ripening and decay. These pathogens, pests, and gases accumulate in the storage environment and spread through the ventilation holes to produce outside the monitoring box, causing more produce to rot and accelerating the ripening and decay of produce around the monitoring box.

[0005] During transportation, vehicles encounter uneven road conditions, causing bumps and knocks that can damage the agricultural products in the monitoring box. This damages the epidermal cells of fruits and vegetables, disrupting cell integrity, accelerating respiration, and causing the fruits and vegetables to soften and change color. At the same time, the knocks and knocks can also damage the barriers of fruits and vegetables, making it easier for microorganisms to invade and multiply, producing softening enzymes, pigments, etc., leading to the spoilage of fruits and vegetables.

[0006] Therefore, a monitoring box for agricultural product transportation that can monitor temperature and humidity without electricity was proposed to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose an agricultural product transportation monitoring box with non-electric temperature and humidity monitoring, so as to solve the problem that the existing monitoring boxes cannot detect temperature and humidity for a long time and are not resistant to impacts.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an agricultural product transportation monitoring box with non-electrical temperature and humidity monitoring, comprising a monitoring box body, a box cover rotatably connected to the monitoring box body, fixed ventilation holes equidistantly through the surface of the monitoring box body, an inner liner inside the monitoring box body, the bottom of the inner wall of the inner liner being inclined, and the agricultural product transportation monitoring box with non-electrical temperature and humidity monitoring includes: a buffer shock absorption mechanism and a temperature and humidity detection mechanism, the buffer shock absorption mechanism being located between the bottom of the inner liner and the monitoring box body, and the temperature and humidity detection mechanism being located on both sides of the monitoring box body;

[0009] The buffer and shock absorption mechanism is used to prevent the vegetables and fruits inside the inner liner from being bumped or knocked during transportation;

[0010] The temperature and humidity detection mechanism is used to detect the temperature and humidity of the internal environment of the monitoring box and to serve as a warning.

[0011] Preferably, the buffer and shock absorption mechanism includes shock absorption springs, which are uniformly and fixedly connected to the bottom of both the monitoring box body and the inner liner. Sliding shafts are uniformly and fixedly connected to the bottom of the inner wall of the monitoring box body. Shock absorption tubes are symmetrically slidably connected to the two sliding shafts. A horizontal spring is fixedly connected between the two shock absorption tubes on the same side. Both horizontal springs are sleeved on the surface of the sliding shaft on the same side. A connecting rod is rotatably connected between the outer surface of the bottom of the inner liner and the shock absorption tube.

[0012] Preferably, the temperature and humidity detection mechanism includes a red warning plate. A first sliding groove is formed inside the monitoring box body, and the red warning plate is slidably connected to this first sliding groove. Movable ventilation holes are equidistantly formed on the surface of the red warning plate. Vertical springs are fixedly connected to both sides of the red warning plate, with the bottom ends of the springs fixedly connected to the monitoring box body. A guide rail is fixedly connected to the inner wall of the monitoring box body near the red warning plate. A sliding block is slidably connected to the guide rail, and a memory metal spring is fixedly connected between the sliding block and the top of the guide rail. A locking rod is fixedly connected to the lower end of the red warning plate. A first horizontal groove is formed inside the monitoring box body near the red warning plate, and a locking plate is slidably connected to this first horizontal groove. A compression spring is fixedly connected between the end of the locking plate away from the sliding block and the monitoring box body.

[0013] Preferably, a second sliding groove is provided on the side of the monitoring box body away from the red warning plate, and a blue warning plate is slidably connected in the second sliding groove. Auxiliary springs are fixedly connected to both sides of the blue warning plate, and the bottom end of the auxiliary springs is fixedly connected to the monitoring box body.

[0014] Preferably, a second horizontal groove is provided inside the monitoring box body on the side near the blue warning plate. A limiting spring is fixedly connected to both sides of the second horizontal groove, and a limiting block is fixedly connected to the end of each of the two limiting springs that are close to each other. A limiting plate is fixedly connected to the side of the blue warning plate near the second horizontal groove.

[0015] Preferably, a drain hole is provided at the lower end of the inner liner near the blue warning board, and the drain hole is connected to the inner liner. Slide rails are symmetrically fixedly connected to the lower end of the monitoring box body near the blue warning board, and a water storage tank is slidably connected between the two slide rails.

[0016] Preferably, a support plate is fixedly connected to the lower end of the monitoring box body, and a pry plate is rotatably connected to the top of the support plate. The end of the pry plate near the water storage tank abuts against the bottom of the water storage tank, and the end of the pry plate near the blue warning plate abuts against the bottom of the blue warning plate.

[0017] Compared with the prior art, the present invention provides an agricultural product transportation monitoring box with non-electric temperature and humidity monitoring, which has the following beneficial effects:

[0018] 1. Through the buffer and shock absorption mechanism, the combination of shock-absorbing springs and horizontal springs, this combination of horizontal and vertical shock absorption can more effectively reduce the resonance force of the mechanical system and prevent structural damage caused by the vibration support force reaching its limit. This is because the horizontal and vertical shock absorbers can work together to suppress vibrations in different directions, thereby reducing the possibility of resonance. Secondly, the combination of horizontal and vertical shock absorption can improve the stability and reliability of the monitoring box body. When the monitoring box body is subjected to impacts or vibrations from different directions, the buffer and shock absorption mechanism can effectively absorb and disperse these energies, reduce the damage to the inner liner, and extend the service life of the monitoring box body. This means that during the transportation of fruits and vegetables, no matter what direction of vibration or impact occurs during transportation, the fruits and vegetables can be fully protected. This greatly reduces the damage to fruits and vegetables caused by bumps during transportation and solves the problem of accelerated rotting of fruits and vegetables caused by bumps.

[0019] 2. The pop-up blue warning board in the temperature and humidity detection mechanism can serve as a warning to the personnel in charge of the vehicle. After seeing it, the personnel can clearly understand that the humidity inside the monitoring box has increased to a certain threshold. The personnel can take appropriate measures in time to help avoid problems such as mold and spoilage of agricultural products caused by excessive humidity, thus ensuring the quality and safety of agricultural products. At the same time, the inclined bottom of the inner liner can ensure that water will not accumulate inside the inner liner, greatly reducing the possibility of mold growth and maintaining the hygiene and safety of food.

[0020] 3. When the monitoring personnel see the red warning board pop up, they can quickly take corresponding measures to adjust the situation, thus avoiding the spoilage, mold, or rot of agricultural products caused by rising temperatures. Furthermore, since the temperature and humidity monitoring mechanism does not require a power supply, it can continuously monitor the temperature and humidity inside the monitoring box during long-distance transportation. This independence and reliability are especially important for the use of the monitoring box in remote areas, outdoor environments, or emergency situations.

[0021] 4. Simultaneously, the pop-up red warning panel effectively blocks the airflow between the monitoring box and the outside air through the fixed and movable ventilation holes. This solves the problem of pathogens and pests generated during the decay of agricultural products that require air circulation to maintain freshness, or the release of ethylene gas during the decay process, spreading to agricultural products outside the monitoring box through the fixed and movable ventilation holes, causing more agricultural products to rot and accelerating the ripening and decay process of agricultural products around the monitoring box.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0046] Embodiments of the present invention

[0047] Please refer to Figures 2 to 4 As shown:

[0048] To address the problems mentioned in the technical solutions, this application provides an agricultural product transportation monitoring box with non-electrical temperature and humidity monitoring, including a monitoring box body 1, a box cover 2 rotatably connected to the monitoring box body 1, fixed ventilation holes 21 equidistantly through the surface of the monitoring box body 1, and an inner liner 22 inside the monitoring box body 1, the bottom of the inner wall of the inner liner 22 being inclined. An agricultural product transportation monitoring box with non-electrical temperature and humidity monitoring includes: a buffer shock absorption mechanism and a temperature and humidity detection mechanism, the buffer shock absorption mechanism being located between the bottom of the inner liner 22 and the monitoring box body 1, and the temperature and humidity detection mechanism being located on both sides of the monitoring box body 1;

[0049] The cushioning and shock absorption mechanism is used to prevent vegetables and fruits inside the inner liner 22 from being bumped or knocked during transportation;

[0050] The temperature and humidity detection device is used to detect the temperature and humidity inside the monitoring box 1 and to serve as a warning.

[0051] The buffer and shock absorption mechanism includes shock absorption springs 301, which are uniformly and fixedly connected to the bottom of the monitoring box body 1 and the inner liner 22. Sliding shafts 302 are uniformly and fixedly connected to the bottom of the inner wall of the monitoring box body 1. Shock absorption tubes 303 are symmetrically slidably connected to the two sliding shafts 302. Horizontal springs 304 are fixedly connected between the two shock absorption tubes 303 on the same side. The two horizontal springs 304 are sleeved on the surface of the sliding shafts 302 on the same side. A connecting rod 305 is rotatably connected between the bottom outer surface of the inner liner 22 and the shock absorption tubes 303.

[0052] The inner liner 22 has an inclined bottom surface, and the shock-absorbing spring 301 is sleeved on the surface of the telescopic tube. The upper and lower ends of the telescopic tube are fixedly connected to the inner liner 22 and the monitoring box body 1, respectively. The telescopic tube is used to limit the direction of the monitoring box body 1 when it shakes, so as to ensure that the monitoring box body 1 can shake in the vertical direction.

[0053] In the existing technology, when the vehicle is transporting the monitoring box body 1, it will bump and jolt on the uneven road conditions. The bumps will cause the agricultural products in the monitoring box to collide and bruise. This will damage the epidermal cells of fruits and vegetables, which will destroy the integrity of the cells, accelerate respiration, and make the fruits and vegetables soft and discolored. At the same time, the collision will also damage the barrier of fruits and vegetables, making it easier for microorganisms to invade and multiply in large numbers, producing softening enzymes, pigments, etc., leading to the spoilage of fruits and vegetables.

[0054] Compared with the prior art, the implementation of this embodiment, through the damping of the inner liner 22 by the four damping springs 301 in the buffer mechanism, and the movement of the connecting rod 305 to compress the horizontal spring 304, the combination of horizontal and vertical damping effects can more effectively reduce the resonance force of the mechanical system and prevent structural damage caused by the vibration support force reaching its limit. This is because the horizontal and vertical dampers can work together to suppress vibrations in different directions, thereby reducing the possibility of resonance. Secondly, the combination of horizontal and vertical damping can improve the stability and reliability of the monitoring box body 1. When the monitoring box body 1 is subjected to impacts or vibrations from different directions, the buffer mechanism can effectively absorb and disperse these energies, reduce the damage to the inner liner 22, and extend the service life of the monitoring box body 1. This means that during the transportation of fruits and vegetables, no matter what direction of vibration or impact occurs during transportation, the fruits and vegetables can be fully protected. This greatly reduces the damage to fruits and vegetables caused by bumps during transportation and solves the problem of accelerated rotting of fruits and vegetables caused by collisions.

[0055] Further examples: Please refer to Figures 5 to 16 As shown:

[0056] The temperature and humidity detection mechanism includes a red warning plate 401. A first sliding groove is opened inside the monitoring box body 1. The red warning plate 401 is slidably connected to the first sliding groove opened inside the monitoring box body 1. Movable ventilation holes 419 are equidistantly opened on the surface of the red warning plate 401. Vertical springs 402 are fixedly connected to both sides of the red warning plate 401. The bottom end of the vertical springs 402 is fixedly connected to the monitoring box body 1. A guide rail 403 is fixedly connected to the inner wall of the monitoring box body 1 near the red warning plate 401. A sliding block 408 is slidably connected to the guide rail 403. A memory metal spring 404 is fixedly connected between the sliding block 408 and the top of the guide rail 403. A snap-fit ​​rod 405 is fixedly connected to the lower end of the red warning plate 401. A first horizontal groove is opened inside the monitoring box body 1 near the red warning plate 401. A snap-fit ​​plate 407 is slidably connected in the first horizontal groove. A compression spring 406 is fixedly connected between the end of the snap-fit ​​plate 407 away from the sliding block 408 and the monitoring box body 1.

[0057] A second slide groove is provided on the side of the monitoring box body 1 away from the red warning plate 401. A blue warning plate 409 is slidably connected in the second slide groove. Auxiliary springs 410 are fixedly connected to both sides of the blue warning plate 409. The bottom of the auxiliary springs 410 is fixedly connected to the monitoring box body 1.

[0058] The monitoring box body 1 has a second horizontal groove inside on the side near the blue warning plate 409. Both sides of the second horizontal groove are fixedly connected to a limiting spring 411. The ends of the two limiting springs 411 that are close to each other are fixedly connected to a limiting block 412. The side of the blue warning plate 409 near the second horizontal groove is fixedly connected to a limiting plate 413.

[0059] A drain hole 414 is provided at the lower end of the inner liner 22 near the blue warning plate 409. The drain hole 414 is connected to the inner liner 22. Slide rails 416 are symmetrically fixedly connected at the lower end of the monitoring box body 1 near the blue warning plate 409. A water storage tank 415 is slidably connected between the two slide rails 416.

[0060] A support plate 418 is fixedly connected to the lower end of the monitoring box body 1. A pry plate 417 is rotatably connected to the top of the support plate 418. The end of the pry plate 417 near the water storage tank 415 abuts against the bottom of the water storage tank 415, and the end of the pry plate 417 near the blue warning plate 409 abuts against the bottom of the blue warning plate 409.

[0061] Among them: the memory metal spring 404 is memory metal, which is mainly made of nickel-titanium alloy. At high temperature, this alloy can be molded into any desired shape, while at a lower temperature, the memory metal can be stretched. The temperature at which the memory metal deforms without being subjected to external force is called the wake-up temperature. The wake-up temperature of the memory metal can be set by the ratio of nickel to titanium. The fixed ventilation hole 21 on the red warning plate 401 is set to coincide with the fixed ventilation hole 21 on the monitoring box body 1.

[0062] In existing technologies, during long-distance transportation, the monitoring box faces the problem of insufficient backup power, leading to power outages and equipment malfunctions. This prevents the monitoring system from continuing to monitor the transportation environment of agricultural products, such as key parameters like temperature and humidity. Furthermore, increased temperature and humidity can cause agricultural products to spoil, mold, or rot. Without power, the monitoring box cannot effectively alert outsiders to rising temperatures and humidity. Additionally, for agricultural products requiring proper air circulation to maintain freshness and prevent spoilage, fixed ventilation holes 21 and movable ventilation holes 419 are provided, such as apples, pears, citrus fruits, and tomatoes. When agricultural products such as cucumbers spoil and rot, they are left unattended. Due to the fixed ventilation hole 21 and the movable ventilation hole 419, pathogens or pests generated by the rotting agricultural products cannot be controlled in a timely manner. At the same time, the agricultural products release ethylene gas during the rotting process. Ethylene is a plant hormone that can promote the ripening and rotting of fruits. These pathogens, pests and gases will accumulate in the storage environment. They will spread to agricultural products outside the monitoring box through the fixed ventilation hole 21 and the movable ventilation hole 419, causing more agricultural products to rot and accelerating the ripening and rotting process of agricultural products around the monitoring box.

[0063] Compared with the prior art, the implementation of this embodiment, through the temperature and humidity detection mechanism, can automatically pop up the red warning plate 401 and the blue warning plate 409. Moreover, the temperature and humidity detection mechanism does not require a power supply, which can continuously detect the temperature and humidity in the monitoring box 1 during long-distance transportation. This independence and reliability are particularly important for the use of the monitoring box 1 in remote areas, outdoor environments, or emergency situations. At the same time, by popping up the red warning plate 401, the air in the monitoring box 1 can be effectively blocked from flowing with the outside air through the fixed ventilation hole 21 and the movable ventilation hole 419. This solves the problem that pathogens and pests produced by the decay of agricultural products that require air circulation to maintain freshness, or ethylene gas released during the decay process, can spread to agricultural products outside the monitoring box through the fixed ventilation hole 21 or the movable ventilation hole 419, causing more agricultural products to rot and accelerating the ripening and decay process of agricultural products around the monitoring box.

[0064] The working principle of all the content in the above embodiments is as follows:

[0065] In the initial state: Fruits, vegetables, ice packs or ice cubes are placed in the inner liner 22, the monitoring box body 1 is in the cargo box of the transport vehicle, the lid 2 is closed, the vertical spring 402, the compression spring 406, the auxiliary spring 410 and the limiting spring 411 are all in the compressed state, no water has flowed into the water storage tank 415, the memory metal spring 404 is in the stretched state, the temperature in the monitoring box body 1 is not high enough to reach the wake-up temperature of the memory metal spring 404, and neither the blue warning plate 409 nor the red warning plate 401 has popped out.

[0066] The following describes the working process of the buffer and shock absorption mechanism to prevent damage to the vegetables and fruits inside the inner liner 22 caused by bumps during transportation of the monitoring box:

[0067] During the transportation of the monitoring box body 1, the vehicle may experience bumps and jolting on uneven road conditions, causing the monitoring box body 1 inside the vehicle to collide. This causes the inner liner 22 inside the monitoring box body 1 to shake. The shock-absorbing springs 301, fixedly connected to the bottom of the inner liner 22, are compressed. Because the shock-absorbing springs 301 are evenly distributed around the inner liner 22, they can more evenly distribute and absorb the energy generated by vibration, preventing damage or failure due to localized overload. Simultaneously, when the inner liner 22 shakes, the connecting rod 305, rotatably connected to the inner liner 22, can push the shock-absorbing tubes 303 to move. The shock-absorbing tubes 303 slide away from or towards each other on the sliding shaft 302. The horizontal springs 304 fixedly connected between the shock-absorbing tubes 303 are also compressed or stretched. This combination of horizontal and vertical shock absorption effects can more effectively... Reducing the resonance force of the mechanical system and preventing structural damage caused by the vibration support force reaching its limit is achieved because horizontal and vertical shock absorbers can work together to suppress vibrations in different directions, thereby reducing the possibility of resonance. Secondly, the combination of horizontal and vertical shock absorption can improve the stability and reliability of the monitoring box body 1. When the monitoring box body 1 is subjected to impacts or vibrations from different directions, the buffer shock absorption mechanism can effectively absorb and disperse these energies, reduce the damage to the inner liner 22, and extend the service life of the monitoring box body 1. This means that during the transportation of fruits and vegetables, no matter what direction of vibration or impact occurs during transportation, the fruits and vegetables can be fully protected. This greatly reduces the damage to fruits and vegetables caused by bumps during transportation and solves the problem of accelerated rotting of fruits and vegetables caused by collisions.

[0068] Please refer to the above work process. Figures 2 to 4 .

[0069] The following is the working process of the humidity and temperature detection agency detecting and issuing warnings regarding the humidity and temperature inside the monitoring box 1:

[0070] Before transportation, ice packs or ice cubes are placed in the inner liner 22 to extend the preservation time. During the long-term transportation of the monitoring box body 1, the outer packaging of the ice packs may be damaged due to bumps and knocks on the road, thus increasing the contact area between the ice packs and the external environment. Heat from the external environment can be more easily transferred to the inside of the ice packs, accelerating the melting process of the ice. Because the bottom of the inner liner 22 is sloping, water droplets generated by condensation on the surface of the ice packs, or water droplets flowing out from the broken ice packs, will flow from the sloping bottom of the inner liner 22 through the drain hole 414 into the water storage tank 415. This prevents the accumulation of water from providing a growth environment for bacteria and mold, which would accelerate the spoilage of vegetables and fruits. At this time, the water storage tank 415 will exert a force on the pry plate 417. As the ice pack or ice cube melts, the depth of water flowing into the water storage tank 415 increases, and the weight in the water storage tank 415 gradually increases. As the water volume in the water storage tank 415 gradually increases, the downward force exerted by the water storage tank 415 on the pry plate 417 gradually increases, and the upward force exerted by the pry plate 417 on the blue warning plate 409 also increases. This continues until the upward force of the blue warning plate 409 is sufficient to push the symmetrical limiting blocks 412 away from each other on the inclined surfaces of the limiting plate 413, which is fixedly connected to the blue warning plate 409. At this point, the limiting spring 411 is compressed. During the upward movement of the blue warning plate 409, after the limiting plate 413 passes between the symmetrical limiting blocks 412, the fixed surfaces on both sides of the blue warning plate 409... The auxiliary spring 410 is initially in a compressed state. Therefore, the compressed auxiliary spring 410 is no longer obstructed by the two limiting blocks 412. The auxiliary spring 410 releases its compressed elastic potential energy. The blue warning plate 409 is subjected to an upward elastic force by the auxiliary spring 410. Therefore, under the action of the elastic force of the auxiliary spring 410, the blue warning plate 409 pops out onto the upper surface of the monitoring box body 1. Since the blue warning plate 409 is blue, it can serve as a warning to the staff. After the supervisor sees it, they can clearly understand that the air humidity inside the monitoring box body 1 has increased to a certain threshold. This is because ice melting into water releases water vapor, which enters the air inside the refrigerator, causing the air humidity to rise. The pop-out of the blue warning sign 409 indicates that the ambient temperature inside the monitoring box 1 is continuously rising. The vegetables or fruits in the inner liner 22 will not spoil or rot in this temporarily elevated temperature environment. The staff can take timely measures to prevent mold and spoilage caused by excessive humidity, ensuring the quality and safety of the produce. Therefore, after seeing the blue warning sign 409 pop out, the staff will promptly remove the produce from the inner liner 22. After removing the produce, the staff will remove the inner liner 22 from the monitoring box 1, then slide the water tank 415 out of the slide rail 416, empty the water from the water tank 415, and then place the water tank 415 back between the slide rails 416. The inner liner 22 will then be placed back into the monitoring box 1.The supervisor then manually presses down the blue warning panel 409 until the restriction panel 413 is below the restriction block 412, restoring it to its initial state.

[0071] Furthermore, since the memory metal spring 404 is a memory metal, this means that the critical temperature at which fruits and vegetables will spoil and rot can be set as the activation temperature of the memory metal spring 404. Because different fruits and vegetables have different critical temperatures for spoilage, the activation temperature of the memory metal spring 404 can be set according to the type of fruits and vegetables being transported. Since the ice packs or ice cubes placed in the inner liner 22 will gradually melt, this means that the temperature inside the monitoring box body 1 will gradually rise. When the temperature inside the monitoring box body 1 reaches the critical temperature for spoilage of the fruits and vegetables in the inner liner 22, it means... This means that the ambient temperature inside the monitoring box 1 has reached the wake-up temperature of the memory metal spring 404. At this time, the memory metal spring 404 will deform, mainly due to the phase change within the memory metal material. The memory metal spring 404 will gradually contract and return to its unstretched state. The sliding block 408, which is fixedly connected to the lower end of the memory metal spring 404, will gradually rise. Since the sliding block 408 slides on the guide rail 403, this ensures that the sliding block 408 will not affect the deformation of the memory metal spring 404 due to the vehicle's swaying during bumpy rides. As the metal spring 404 continuously contracts, the sliding block 408 rises continuously, releasing its obstruction of the locking plate 407. Since a compression spring 406 is fixedly connected to the end of the locking plate 407 furthest from the sliding block 408, after the sliding block 408 releases its obstruction, the compression spring 406 pushes the locking plate 407 towards the sliding block 408. This releases the locking plate 407 from its engagement with the locking rod 405, meaning the red warning plate 401, fixedly connected to the locking rod 405, will activate on both sides of the vertical springs 402. Under the action of elasticity, the red warning plate 401 moves upward, and eventually the red warning plate 401 can pop out of the surface of the monitoring box body 1, which means that the ambient temperature in the monitoring box body 1 has reached the critical temperature for the vegetables and fruits to spoil. The supervisor can detect the temperature abnormality in time and take corresponding measures to adjust it quickly. Since the temperature and humidity detection mechanism does not require a power supply, it can continuously detect the temperature and humidity in the monitoring box body 1 during long-distance transportation. Moreover, this independence and reliability are particularly important for the use of the monitoring box body 1 in remote areas, outdoor environments or emergency situations.

[0072] Meanwhile, since the red warning plate 401 has a movable ventilation hole 419, after the red warning plate 401 pops out, the movable ventilation hole 419 on the red warning plate 401 no longer coincides with the fixed ventilation hole 21 on the monitoring box body 1. This means that the air inside the monitoring box body 1 no longer circulates with the outside air. After the guards finish processing the agricultural products in the inner liner 22, they will put ice packs and agricultural products back into the inner liner 22. After waiting for the temperature inside the monitoring box body 1 to drop below the activation temperature of the memory metal spring 404, the guards will first take out the inner liner 22. Then, before the temperature reaches the activation temperature of the memory metal spring 404, the guards will press the red warning plate 401 with one hand while pushing the sliding block down with the other hand. 408. The red warning plate 401 first returns to its initial state. Then, when the sliding block 408 returns to its initial position, it will push the locking plate 407 to move away from the sliding block 408 until the locking rod 405 and the locking plate 407 are locked together. The red warning plate 401 will no longer pop out. Finally, the inner liner 22 is placed into the monitoring box body 1, and the box cover 2 is closed to restore the monitoring box body 1 to its initial state. This solves the problem that pathogens and pests produced by the rotting of agricultural products that require air circulation to maintain freshness, or ethylene gas released during the rotting process, spread to agricultural products outside the monitoring box through the fixed ventilation hole 21 and the movable ventilation hole 419, causing more agricultural products to rot and accelerating the ripening and rotting process of agricultural products around the monitoring box.
