[0003] For example, the invention published with the publication number CN118872872B discloses a fruit and vegetable drying storage device for storing agricultural products.

[0004] The above technical solutions still have the following deficiencies in the use process:

[0005] 1. The above technical solution stores fruits and vegetables through a box body. When the corresponding box body is pulled out and the corresponding fruits and vegetables are taken out, while the storage capacity of the fruits and vegetables is reduced, the occupied space of the device will not decrease. Therefore, as the fruits and vegetables are continuously taken away, the device still occupies a large amount of space, affecting the storage of other fruits and vegetables in the later stage;

[0006] 2. When the box body is taken out and the amount of fruits and vegetables decreases, the cold air or water mist in the device still fills the entire air duct, resulting in a large amount of cold air or water mist not being effectively utilized.

[0007] In view of the above problems, the present invention document proposes an agricultural product and fruit and vegetable storage device and method with precise temperature and humidity control and classification ability. Summary of the Invention

[0014] In a possible design, the temperature and humidity control structure includes a recovery tank and a control chamber respectively arranged inside the chassis and the top plate. The recovery tank and the control chamber are connected through a hose. An atomizer is fixed on the inner wall of the bottom of the recovery tank and is used to atomize the water in the recovery tank and discharge it into the control chamber through the hose. A carbon resistance wire heating sheet and a refrigerating sheet are fixed on the inner wall of the top of the control chamber and are used to heat and refrigerate the air in the control chamber. Two round holes are arranged on the top of the top plate and are connected to the control chamber. Two fans are fixed in the two round holes respectively and are used to inject external air into the control chamber; According to needs, the carbon resistance wire heating sheet and the refrigerating sheet are started. The fans inject external air into the control chamber. The carbon resistance wire heating sheet and the refrigerating sheet heat and refrigerate the air according to needs. The air in the control chamber enters the fixed column and is discharged into the storage box through the first through hole to control the temperature of the fruits and vegetables in the storage box; The atomizer atomizes the filtered water. The atomized water droplets enter the control chamber through the hose, and then enter the corresponding storage boxes respectively through the cooperation of the second conduit and a plurality of fixed columns to control the humidity in the storage boxes.

[0015] In a possible design, the connection structure includes a fixed column fixed on the inner wall of the bottom of the storage box. A communication hole is arranged at the top of the fixed column. A connection frame is fixed in the communication hole. A first magnet is fixed at the top of the connection frame. A second conduit is fixed on the inner wall of the bottom of the top plate. The inner wall of the bottom of the fixed column is fixedly penetrated by a first conduit, and the bottom end of the first conduit is fixedly penetrated through the storage box. The first conduit cooperates with the adjacent communication hole and the second conduit. Fixed rings are fixed in both the first conduit and the second conduit. A plurality of guide rods are fixed on the top of each fixed ring. The outer walls of the plurality of guide rods are slidably sleeved with the same closing plate. A second magnet is fixed at the bottom of the closing plate, and a repulsive force is generated between the second magnet and the adjacent first magnet to release the closing of the corresponding first conduit and second conduit by the fixed ring and the closing plate. A plurality of first through holes are arranged on the outer wall of the fixed column and are used to allow air and water mist to enter the storage box; After a plurality of storage boxes are stacked and the top plate is placed on the top of the uppermost storage box, a repulsive force is generated between the second magnet and the adjacent first magnet, so as to be able to release the closing of the first conduit and the second conduit, and enable air and water mist to enter the storage box in sequence to complete the temperature and humidity control of the fruits and vegetables.

[0016] In a possible design, the material taking structure includes two fixed rods penetrating through the top plate. The outer walls of the two fixed rods are sleeved with the same connecting plate. A same rotating column is rotatably penetrated through the connecting plate. The rotating column is connected to the two fixed rods through synchronous pulleys and synchronous belts. A torsion spring fixedly connected to the bottom of the connecting plate is sleeved on the outer wall of the rotating column. The bottom end of the torsion spring is fixedly connected to the outer wall of the rotating column. The outer walls of the two fixed rods are fixedly sleeved with shift rods. U-shaped handles are fixed on both sides of the storage box, and the U-shaped handles are engaged with the shift rods for clamping with the corresponding storage box. A threaded cylinder is fixed on the top of the chassis. A threaded rod is screwed in the threaded cylinder. The top end of the threaded rod is rotatably connected to the bottom of the top plate. A motor for driving the threaded rod to rotate is arranged in the top plate. The cooperation of the threaded cylinder and the threaded rod is used to drive the top plate and the corresponding storage box to rise; the rotating column drives the fixed rod and the shift rod to rotate through the synchronous pulley and the synchronous belt. The shift rod disengages from the U-shaped handle, and then the rotating column drives the connecting plate and the fixed rod to lift to a position above the storage box where the fruits and vegetables to be taken out are located. The rotating column rotates back under the action of the torsion spring, and the shift rod is inserted into the corresponding U-shaped handle. Then, the motor drives the threaded rod to rotate, driving the top plate and multiple storage boxes above the storage box where the fruits and vegetables to be taken out are located to move upward, so that the corresponding storage box can be taken out. After taking out, the threaded rod rotates reversely, stacking the multiple storage boxes again for continuous storage. After taking out the corresponding storage box, the overall height of the device is reduced, reducing the space occupancy rate.

[0017] In a possible design, a plurality of baffle plates are rotatably sleeved on the outer wall of the fixed column. A storage space is formed between adjacent two baffle plates and the storage box. The plurality of baffle plates cooperate to control the size of the storage space. A temperature and humidity sensor is fixedly embedded on one side of one of the baffle plates for real-time monitoring of the temperature and humidity in the storage box.

[0018] In a possible design, a label slot is arranged on one side of the storage box for placing a label of the type of fruits and vegetables stored in the storage box. A partition is fixed in the recovery tank. An activated carbon layer is fixed in the partition for filtering water, facilitating the atomizer to atomize the water in the later stage.

[0019] In a possible design, an air filter screen is fixed in the round hole for filtering the air entering the control cavity. A plurality of ultraviolet germicidal lamps are fixed on the bottom inner wall of the control cavity for sterilizing the air in the control cavity.

[0020] In a possible design, liquid collecting grooves are provided in multiple storage boxes, a plurality of liquid leakage holes are provided on the inner bottom walls of the multiple storage boxes, and the liquid leakage holes communicate with the liquid collecting grooves. Liquid guiding pipes are fixed in the multiple storage boxes, the bottom ends of the liquid guiding pipes extend into the liquid collecting grooves, the top ends of the liquid guiding pipes extend above the storage boxes, a connection hole is provided at the bottom of the storage box, and the connection hole is docked with the adjacent liquid guiding pipe, which is convenient for guiding the accumulated water in the liquid collecting groove downward and can also position two adjacent storage boxes. A collecting pipe communicating with the recovery groove is fixed in the chassis, the top end of the collecting pipe extends above the chassis and is communicated with the adjacent connection hole, and is used for guiding the accumulated water in the lowermost liquid collecting groove back to the recovery groove; when stacking multiple storage boxes, the multiple storage boxes can be stacked neatly by docking the liquid guiding pipe with the adjacent connection hole, and the accumulated water in the multiple storage boxes can be gathered and discharged into the recovery groove for recycling the accumulated water.

[0021] In a possible design, a closing ring for closing the first through hole is slidably connected in the fixed column, a connecting ear is fixed on one inner wall of the closing ring, a lead screw is threadedly penetrated through the connecting ear, and the cooperation between the lead screw and the connecting ear is used to control the lifting of the closing ring. The bottom end of the lead screw rotates and extends into the liquid collecting groove and is rotatably connected to the inner bottom wall of the liquid collecting groove. A first bevel gear is fixedly sleeved on the outer wall of the lead screw. A driving rod is rotatably connected in the liquid collecting groove through a base. A second bevel gear meshing with the first bevel gear is fixed at one end of the driving rod. The other end of the driving rod rotates and extends to one side of the storage box and is fixed with a handle; when it is necessary to control the amount of air and water mist entering the storage box in the fixed column so as to control the temperature and humidity in the storage box, the lead screw is rotated by rotating the driving rod, the lead screw drives the closing ring to lift, and further the shielding area of the closing ring for the first through hole can be controlled, so as to complete the control of the amount of air and water mist entering the storage box.

[0022] In this application, a method for using an agricultural product and fruit and vegetable storage device with precise temperature and humidity control and classification includes the following steps:

[0023] S1. According to the number of fruits and vegetables stored in the storage box, by rotating the baffle, the distance between two adjacent baffles can be adjusted, so that different numbers of fruits and vegetables can be placed. Then, multiple storage boxes are stacked from top to bottom and placed on the top of the chassis, and the motor drives the threaded rod to rotate, and the threaded rod drives the top plate to move downward to close the uppermost storage box;

[0024] S2. In addition, the temperature and humidity in the storage box can be monitored in real time through the temperature and humidity sensor. When the temperature needs to be controlled, the carbon resistance wire heating plate and the cooling plate are started as needed, and the fan injects the outside air into the control chamber. The carbon resistance wire heating plate heats the air, and the cooling plate cools the air. Since the top plate is placed on the top storage box, a repulsive force is generated between the first magnet in the second conduit and the adjacent second magnet, so that the closing plate and the second magnet move upward, and the closing plate and the fixing ring release the closing of the second conduit. At this time, the air in the control chamber enters the fixing column and is discharged into the storage box through the first through hole, so that the temperature of the fruits and vegetables in the storage box is controlled;

[0025] S3. When humidity control is performed, the activated carbon layer filters the water in the recovery tank, and the atomizer atomizes the filtered water. The atomized water droplets enter the control cavity through the hose, and then enter the corresponding storage boxes through the cooperation of the second guide tube and multiple fixed columns to control the humidity in the storage box. When there is too much water in the storage box, it flows into the liquid collecting tank through the leakage hole, and the water can be collected in the recovery tank for recycling through the cooperation of the liquid guide tube, the connecting hole and the collection tube; when drying is required, the air is heated by the carbon resistance wire heating sheet and the air is injected into the storage box in turn, and the moisture is discharged into the recovery tank through the leakage hole, the liquid collecting tank, the liquid guide tube and the collection tube to complete the drying of fruits and vegetables;

[0026] S4. When it is necessary to take out the fruits and vegetables in the corresponding storage box, the rotating column is rotated. The rotating column drives the fixed rod and the lever to rotate through the synchronous wheel and the synchronous belt. The lever is disengaged from the U-shaped handle, and then the connecting plate and the fixed rod are driven to rise and fall to the position above the storage box for the fruits and vegetables to be taken out through the rotating column. The rotating column is reset and rotated under the action of the torsion spring, and the lever is inserted into the corresponding U-shaped handle. Then, the threaded rod is driven by the motor to rotate, and the top plate and multiple storage boxes above the storage box for the fruits and vegetables to be taken out are driven to move upward, so that the corresponding storage box can be taken out. After taking out, the threaded rod rotates in the opposite direction, and the multiple storage boxes are stacked again to continue storage. After taking out the corresponding storage box, the overall height of the device is reduced, and the space occupancy rate is reduced. After the corresponding storage box is taken out, the space for arranging cold air and water mist in the storage box is also reduced, so as to avoid waste of air and water mist.

[0027] S5. When it is necessary to control the amount of air and water mist in the fixed column entering the storage box, so as to control the temperature and humidity in the storage box, the drive rod is rotated to drive the screw to rotate with the cooperation of the first bevel gear and the second bevel gear. The screw drives the closed ring to rise and fall, and then the blocking area of the closed ring to the first through hole can be controlled, thereby completing the amount of air and water mist entering the storage box.

[0028] Beneficial effects: In the present invention, the material taking structure includes two fixing rods passing through the top plate. The outer walls of both fixing rods are fixedly sleeved with dial rods. U-shaped handles are fixed on both sides of the storage box. A threaded cylinder is fixed on the top of the chassis. A threaded rod is in threaded connection with the threaded cylinder. The top end of the threaded rod is rotatably connected to the bottom of the top plate. The rotation control cavity drives the dial rod to disengage from the U-shaped handle, and then drives the connecting plate and the fixing rod to lift to the corresponding position through the rotating column. After that, the dial rod is clamped with the U-shaped handle again. The motor and the threaded rod cooperate to drive the top plate and the storage box to move upward, so that the corresponding storage box can be taken out. After taking out, storage can continue. After taking out the corresponding storage box, the overall height of the device is reduced, reducing the space occupancy rate;

[0029] In the present invention, a first magnet is fixed to the fixed column through a connecting frame. A second conduit is fixed to the inner wall of the bottom of the top plate. A first conduit is fixedly penetrated through the inner wall of the bottom of the fixed column. Fixed rings are fixed in both the first conduit and the second conduit. Sealing plates are slid on the top of the fixed rings through guide rods. A second magnet is fixed to the bottom of the sealing plate. A repulsive force is generated between the second magnet and the adjacent first magnet, which can release the sealing of the first conduit and the second conduit, enabling air and water mist to enter the storage box in sequence to complete the temperature and humidity control of fruits and vegetables. In addition, after one of the storage boxes is taken out, the space for the arrangement of cold air and water mist in the storage box is reduced, avoiding waste of air and water mist;

[0030] In the present invention, a sealing ring is slidably connected in the fixed column. A lead screw is threaded through the inner wall of one side of the sealing ring through a connecting ear. The bottom end of the lead screw rotates and extends into the liquid collecting tank. A driving rod is rotatably connected to the liquid collecting tank through a base. The lead screw and the liquid guide pipe are engaged through a first bevel gear and a second bevel gear. By rotating the driving rod to drive the lead screw to rotate, the lead screw drives the sealing ring to lift, thereby controlling the shielding area of the sealing ring for the first through hole, and thus completing the amount of air and water mist entering the storage box to control the temperature and humidity in the storage box.

[0031] In the present invention, multiple storage boxes can be stacked flexibly to complete the storage of fruits and vegetables. After taking out any one of the storage boxes, the multiple storage boxes can still complete the storage operation, and the height can also be reduced to save space. In addition, as the number of storage boxes decreases, the space for the diffusion of air and water mist can be reduced, making full use of air and water mist and avoiding waste of air and water mist.

Specific implementation manner

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Refer to Figure 1 and Figure 2 , a storage device, which relates to the technical field of storage. The device includes a chassis 1, and a top plate 3 is arranged above the chassis 1. Fixed cylinders 40 are welded on both sides of the top of the chassis 1, and sliding rods 41 are slidably connected in both fixed cylinders 40, and the sliding rods 41 can stably slide in the fixed cylinders 40. The tops of the two sliding rods 41 are fixed to the bottom of the top plate 3 by bolts, so that the top plate 3 can be lifted and lowered stably. A plurality of storage boxes 2 are placed between the chassis 1 and the top plate 3, and the plurality of storage boxes 2 are stacked in sequence from top to bottom, and the storage boxes 2 are located between the two fixed cylinders 40. The storage boxes 2 are used for classifying and storing agricultural products and fruits and vegetables, and the structures of the plurality of storage boxes 2 are the same.

[0047] Refer to Figure 8 and Figure 9, in order to achieve precise control of temperature and humidity, the device is provided with a temperature and humidity control structure. The temperature and humidity control structure includes a recovery tank 23 and a control chamber 28 respectively arranged in the chassis 1 and the top plate 3. The recovery tank 23 is used to collect and store moisture, and the recovery tank 23 is communicated with the control chamber 28 through a hose 27. The bottom inner wall of the recovery tank 23 is fixed with an atomizer 26 by bolts. The atomizer 26 can atomize the moisture in the recovery tank 23 and discharge the atomized water droplets into the control chamber 28 through the hose 27. The top inner wall of the control chamber 28 is respectively fixed with a carbon resistance wire heating sheet 31 and a refrigerating sheet 32 by bolts. The carbon resistance wire heating sheet 31 can heat the air in the control chamber 28, and the refrigerating sheet 32 can cool the air in the control chamber 28. The top of the top plate 3 is provided with two round holes, and the round holes are communicated with the control chamber 28. Two fans 30 are fixed in the two round holes by bolts. The fans 30 can discharge the outside air into the control chamber 28.

[0048] During use, the carbon resistance wire heating sheet 31, the refrigerating sheet 32 and the fans 30 are started according to needs. The fans 30 inject the outside air into the control chamber 28. The carbon resistance wire heating sheet 31 and the refrigerating sheet 32 heat and cool the air according to needs, so as to control the temperature in the control chamber 28. The air in the control chamber 28 enters the storage box 2 through the fixing column 4 to control the temperature of the fruits and vegetables in the storage box 2. At the same time, the atomizer 26 atomizes the filtered water. The atomized water droplets enter the control chamber 28 through the hose 27, and then enter the corresponding storage boxes 2 respectively through the cooperation of the second conduit 34 and multiple fixing columns 4 to control the humidity in the storage boxes 2.

[0049] Refer to Figures 3 - 9, in order to achieve the connection between multiple storage boxes 2, the device is provided with a connection structure. The connection structure includes a fixed column 4 welded to the inner bottom wall of the storage box 2. A communication hole 8 is provided at the top of the fixed column 4. A connection frame 10 is welded in the communication hole 8, and a first magnet 9 is welded to the top of the connection frame 10. A second conduit 34 is welded to the inner bottom wall of the top plate 3. A first conduit 11 is welded through and penetrates the inner bottom wall of the fixed column 4, and the bottom end of the first conduit 11 is welded through the bottom of the storage box 2. The first conduit 11 cooperates with the adjacent communication hole 8 and the second conduit 34, so that air and water mist can flow in multiple storage boxes 2 and the control cavity 28 therebetween. Fixed rings 12 are welded in both the first conduit 11 and the second conduit 34. A plurality of guide rods 13 are welded to the top of each fixed ring 12. The outer walls of the plurality of guide rods 13 are slidably sleeved with the same closing plate 14, and the closing plate 14 is used to close the first conduit 11 and the second conduit 34. A second magnet 15 is welded to the bottom of the closing plate 14, and a repulsive force is generated between the second magnet 15 and the adjacent first magnet 9. When the top plate 3 is placed on the top of the storage box 2 and multiple storage boxes 2 are stacked, the repulsive force between the second magnet 15 and the first magnet 9 can push the closing plate 14 to slide, thereby releasing the closing of the corresponding first conduit 11 and second conduit 34 by the fixed ring 12 and the closing plate 14. A plurality of first through holes 7 are provided on the outer wall of the fixed column 4 for allowing air and water mist to enter the storage box 2.

[0050] Specifically, after multiple storage boxes 2 are stacked and the top plate 3 is placed on the top of the uppermost storage box 2, a repulsive force is generated between the second magnet 15 and the adjacent first magnet 9, pushing the closing plate 14 to slide, thereby releasing the closing of the first conduit 11 and the second conduit 34, enabling air and water mist to enter the storage box 2 in sequence to complete the temperature and humidity control of fruits and vegetables.

[0051] Refer to Figure 2 , Figure 8 and Figure 10, To facilitate the convenient removal and placement of the storage box 2, a material taking structure is provided for the device. The material taking structure includes two fixed rods 36 respectively penetrating through both sides of the top plate 3. These two fixed rods 36 are connected together above the top plate 3 through a connecting plate 35. A rotating column 38 is rotatably penetrated through the connecting plate 35. The rotating column 38 is drivingly connected to both fixed rods 36 through synchronous pulleys and synchronous belts. That is to say, when the rotating column 38 rotates, it will drive the two fixed rods 36 to rotate synchronously. To ensure that the rotating column 38 can maintain a specific position when not affected by external forces, a torsion spring 39 is sleeved on the outer wall of the rotating column 38. The top end of the torsion spring 39 is fixedly connected to the bottom of the connecting plate 35, and the bottom end of the torsion spring 39 is fixedly connected to the outer wall of the rotating column 38. In this way, when an external force acts on the rotating column 38 to make it rotate, once the external force disappears, the elastic force of the torsion spring 39 will cause the rotating column 38 to reset. On the outer walls of the two fixed rods 36, a lever 37 is respectively fixedly sleeved. At the same time, on both sides of the storage box 2, U-shaped handles 20 are fixed. These U-shaped handles 20 are designed to be engaged with the levers 37, so as to realize the clamping connection between the storage box 2 and the material taking structure.

[0052] Refer to Figure 8 , To realize the lifting and lowering of the top plate 3 and the storage box 2, a threaded cylinder 42 is fixed on the top of the chassis 1. A threaded rod 43 is threadedly connected to the threaded cylinder 42. The top end of the threaded rod 43 is rotatably connected to the bottom of the top plate 3. And in the top plate 3, a motor is provided. The output shaft of this motor is connected to the top end of the threaded rod 43 and is used to drive the threaded rod 43 to rotate in the threaded cylinder 42. When the threaded rod 43 rotates, it will drive the top plate 3 and the storage box 2 on the top plate 3 to rise or fall together.

[0053] Specifically, when we need to take out a certain storage box 2, first, rotate the rotating column 38 by an external force. The rotating column 38 drives the two fixed rods 36 and the levers 37 to rotate through synchronous pulleys and synchronous belts, so that the lever 37 disengages from the U-shaped handle 20. Then, drive the connecting plate 35 and the fixed rods 36 to rise and fall to a position above the storage box 2 containing the fruits and vegetables to be taken out through the rotating column 38. At this time, release the external force, and the rotating column 38 rotates back under the action of the torsion spring 39, and the lever 37 is inserted into the corresponding U-shaped handle 20. Next, drive the threaded rod 43 to rotate through the motor. The threaded rod 43 drives the top plate 3 and multiple storage boxes 2 above the storage box 2 containing the fruits and vegetables to be taken out to move upward together through the cooperation of the threaded cylinder 42, so that the corresponding storage box 2 can be taken out. After taking out, drive the threaded rod 43 to rotate reversely through the motor, stack the multiple storage boxes 2 again, and continue to store. In this way, after taking out the corresponding storage box 2, the overall height of the device is reduced, reducing the space occupancy rate.

[0054] Refer to Figure 3 and Figure 4, In addition, we also rotatably sleeved multiple baffles 5 on the outer wall of the fixed column 4, and a storage space is formed between two adjacent baffles 5 and the storage box 2. By adjusting the position of the baffle 5, we can control the size of the storage space to meet the storage requirements of agricultural products or fruits and vegetables of different sizes. On one side of one of the baffles 5, we fixedly installed a temperature and humidity sensor 6 to monitor the temperature and humidity inside the storage box 2 in real time, ensuring that agricultural products or fruits and vegetables can be stored under suitable temperature and humidity conditions.

[0055] Refer to Figure 3 and Figure 8 , For the convenience of management, we set a label slot 21 on one side of the storage box 2 for placing labels of the types of fruits and vegetables stored in the storage box 2. In this way, we can quickly identify the types of agricultural products or fruits and vegetables stored in each storage box 2. In addition, inside the recovery slot 23, we fixed a partition 24 and fixed an activated carbon layer 25 inside the partition 24. The activated carbon layer 25 is designed to filter water, facilitating the later atomizer 26 to atomize the water and providing a suitable humidity environment for the agricultural products or fruits and vegetables in the storage box 2.

[0056] Refer to Figure 9 , An air filter screen 29 is provided in the control cavity 28. The air filter screen 29 is fixed in the round hole, and its function is to filter the air entering the control cavity 28 to remove pollutants such as dust and impurities. At the same time, on the bottom inner wall of the control cavity 28, multiple ultraviolet germicidal lamps 33 are fixed. These ultraviolet germicidal lamps 33 can emit ultraviolet rays to sterilize the air in the control cavity 28, thereby further purifying the air and providing a cleaner storage environment for agricultural products and fruits and vegetables.

[0057] Refer to Figure 2 , Figure 7 and Figure 8, a plurality of storage boxes 2 are provided with a liquid collecting trough 16. The liquid collecting trough 16 is located at the bottom of the storage box 2 and is used to collect the accumulated water that may be generated during the storage of agricultural products and fruits and vegetables. At the same time, the bottom inner wall of the storage box 2 is provided with a plurality of leakage holes 17, which are connected to the liquid collecting trough 16, so that the accumulated water can flow smoothly into the liquid collecting trough 16. In addition, a liquid guide tube 18 is fixed in each storage box 2, and the bottom end of the liquid guide tube 18 extends into the liquid collecting trough 16, and the top end extends to the top of the storage box 2. At the bottom of the storage box 2, a connecting hole 19 is also provided, and the connecting hole 19 is connected to the adjacent liquid guide tube 18. This design is convenient for guiding the accumulated water in the upper liquid collecting trough 16 to the lower liquid collecting trough 16 through the liquid guide tube 18, and can also position two adjacent storage boxes 2 to ensure that they are stacked neatly. In the chassis 1, a collecting pipe 22 connected to the recovery tank 23 is fixed. The top end of the collecting pipe 22 extends to the top of the chassis 1 and is connected to the connecting hole 19 of the bottom storage box 2. In this way, the accumulated water in the bottom liquid collecting tank 16 can be guided back to the recovery tank 23 through the collecting pipe 22 to achieve the recycling of the accumulated water.

[0058] Through the above specific implementation methods, the present invention realizes a storage device for agricultural products and fruits and vegetables with precise temperature and humidity control and classifiable functions. The device has a simple structure and is easy to operate. It can achieve precise temperature and humidity control of agricultural products and fruits and vegetables, thereby improving the preservation effect of agricultural products and fruits and vegetables.

[0059] Example 2: Reference Figure 11 and Figure 12 , improved on the basis of Example 1: a closed ring 44 is slidably connected in the fixed column 4, and the closed ring 44 is used to close the first through hole 7. A connecting ear 45 is fixed to the inner wall of one side of the closed ring 44, and a screw 46 is passed through the inner thread of the connecting ear 45. By rotating the screw 46, the lifting and lowering of the closed ring 44 can be controlled. The bottom end of the screw 46 rotates and extends into the liquid collecting tank 16 and is rotatably connected to the bottom inner wall of the liquid collecting tank 16, and the outer wall of the screw 46 is fixedly sleeved with a first bevel gear 47. In the liquid collecting tank 16, a driving rod 48 is rotatably connected through the base, and one end of the driving rod 48 is fixed with a second bevel gear 49 meshing with the first bevel gear 47, and the other end is rotatably extended to one side of the storage box 2 and fixed with a handle.

[0060] When it is necessary to control the amount of air and water mist in the fixed column 4 entering the storage box 2 to control the temperature and humidity in the storage box 2, the operator can turn the handle to drive the driving rod 48 to rotate. The driving rod 48 drives the first bevel gear 47 to rotate through the second bevel gear 49, thereby driving the screw rod 46 to rotate. The rotation of the screw rod 46 will drive the closed ring 44 to rise and fall, thereby changing the shielding area of the closed ring 44 to the first through hole 7. By adjusting the shielding area, the amount of air and water mist entering the storage box 2 can be controlled, thereby achieving precise control of the temperature and humidity in the storage box 2.

[0061] A method for using a temperature and humidity precise control and classifiable agricultural product fruit and vegetable storage device, comprising the following steps:

[0062] S1. According to the number of fruits and vegetables stored in the storage box 2, the distance between two adjacent baffles 5 can be adjusted by rotating the baffles 5, so that different numbers of fruits and vegetables can be placed. Then, multiple storage boxes 2 are stacked from top to bottom and placed on the top of the bottom plate 1. The threaded rod 43 is driven by the motor to rotate, and the threaded rod 43 drives the top plate 3 to move down and close the top storage box 2.

[0063] S2. In addition, the temperature and humidity in the storage box 2 can be monitored in real time through the temperature and humidity sensor 6. When the temperature needs to be controlled, the carbon resistance wire heating plate 31 and the cooling plate 32 are started as needed, and the fan 30 injects the outside air into the control chamber 28. The carbon resistance wire heating plate 31 heats the air, and the cooling plate 32 cools the air. Since the top plate 3 is placed on the top storage box 2, a repulsive force is generated between the first magnet 9 in the second conduit 34 and the adjacent second magnet 15, so that the closing plate 14 and the second magnet 15 move upward, and the closing plate 14 and the fixing ring 12 release the closing of the second conduit 34. At this time, the air in the control chamber 28 enters the fixing column 4 and is discharged into the storage box 2 through the first through hole 7, so that the temperature of the fruits and vegetables in the storage box 2 is controlled;

[0064] S3. When humidity control is performed, the activated carbon layer 25 filters the water in the recovery tank 23, and the atomizer 26 atomizes the filtered water. The atomized water droplets enter the control chamber 28 through the hose 27, and then enter the corresponding storage box 2 through the cooperation of the second guide tube 34 and the plurality of fixed columns 4, so as to control the humidity in the storage box 2. When there is too much water in the storage box 2, it flows into the liquid collecting tank 16 through the leakage hole 17, and the water can be collected in the recovery tank 23 for recycling through the cooperation of the liquid guide tube 18, the connecting hole 19 and the collecting tube 22; when drying is required, the air is heated by the carbon resistance wire heating sheet 31 and the air is injected into the storage box 2 in sequence, and the moisture is discharged into the recovery tank 23 through the leakage hole 17, the liquid collecting tank 16, the liquid guide tube 18 and the collecting tube 22, so as to complete the drying of fruits and vegetables;

[0065] S4. When it is necessary to take out the fruits and vegetables in the corresponding storage box 2, rotate the rotating column 38. The rotating column 38 drives the fixed rod 36 and the lever 37 to rotate through the synchronous pulley and the synchronous belt. The lever 37 disengages from the U-shaped handle 20, and then drives the connecting plate 35 and the fixed rod 36 to rise and fall to a position above the storage box 2 where the fruits and vegetables to be taken out are located through the rotating column 38. The rotating column 38 rotates back under the action of the torsion spring 39, and the lever 37 is inserted into the corresponding U-shaped handle 20. Then, the motor drives the threaded rod 43 to rotate, driving the top plate 3 and multiple storage boxes 2 above the storage box 2 where the fruits and vegetables to be taken out are located to move upward, so that the corresponding storage box 2 can be taken out. After taking out, the threaded rod 43 rotates in the reverse direction to stack the multiple storage boxes 2 again for continuous storage. Moreover, after taking out the corresponding storage box 2, the overall height of the device decreases, reducing the space occupancy rate. Also, after taking out the corresponding storage box 2, the space for the distribution of cold air and water mist in the storage box 2 is similarly reduced, avoiding the waste of air and water mist;

[0066] S5. When it is necessary to control the amount of air and water mist entering the storage box 2 in the fixed column 4, so as to control the temperature and humidity in the storage box 2, rotate the driving rod 48. Under the cooperation of the first bevel gear 47 and the second bevel gear 49, drive the lead screw 46 to rotate. The lead screw 46 drives the closing ring 44 to rise and fall, and then can control the shielding area of the closing ring 44 for the first through hole 7, thereby completing the control of the amount of air and water mist entering the storage box 2.

[0067] However, as is well known to those skilled in the art, the working principles and wiring methods of the carbon resistance wire heating sheet 31, the refrigeration sheet 32, the ultraviolet germicidal lamp 33, the fan 30, the temperature and humidity sensor 6, and the atomizer 26 are common knowledge. They all belong to conventional means or well-known common sense, and will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

A method of using an agricultural product and fruit and vegetable storage device with precise temperature and humidity control and classification, which is applied to an agricultural product and fruit and vegetable storage device with precise temperature and humidity control and classification described in claim 9, characterized in that, The following steps are involved: S1. According to the quantity of fruits and vegetables stored in the storage box (2), the distance between two adjacent baffles (5) can be adjusted by rotating the baffle (5), so that different quantities of fruits and vegetables can be placed. Then, a plurality of storage boxes (2) are stacked in sequence from top to bottom and placed on the top of the bottom plate (1). The threaded rod (43) is driven to rotate by a motor, and the threaded rod (43) drives the top plate (3) to move downward and close the top storage box (2); S2. In addition, the temperature and humidity in the storage box (2) can be monitored in real time through the temperature and humidity sensor (6). When the temperature needs to be controlled, the carbon resistance wire heating plate (31) and the cooling plate (32) are started as required, and the fan (30) injects external air into the control chamber (28). According to the requirements, the carbon resistance wire heating plate (31) heats the air and the cooling plate (32) cools the air. Since the top plate (3) is placed on the top storage box (2), a repulsive force is generated between the first magnet (9) in the second conduit (34) and the adjacent second magnet (15), thereby causing the closing plate (14) and the second magnet (15) to move upward, thereby releasing the closing plate (14) and the fixing ring (12) from closing the second conduit (34). At this time, the air in the control chamber (28) enters the fixing column (4) and is discharged into the storage box (2) through the first through hole (7), thereby controlling the temperature of the fruits and vegetables in the storage box (2); S3. When humidity control is performed, the activated carbon layer (25) filters the water in the recovery tank (23), and the atomizer (26) atomizes the filtered water. The atomized water droplets enter the control chamber (28) through the hose (27), and then enter the corresponding storage boxes (2) through the cooperation of the second conduit (34) and the plurality of fixed columns (4) to control the humidity in the storage box (2). When there is too much water in the storage box (2), the water droplets flow out through the leakage hole (17). The air is then passed into the liquid collecting tank (16), and the water is collected into the recovery tank (23) for recycling through the cooperation of the liquid guide tube (18), the connecting hole (19) and the collecting tube (22); when drying is required, the air is heated by the carbon resistance wire heating plate (31) and the air is sequentially injected into the storage box (2), and the moisture is discharged into the recovery tank (23) through the liquid leakage hole (17), the liquid collecting tank (16), the liquid guide tube (18) and the collecting tube (22), thereby completing the drying of the fruits and vegetables; S4.

The rotating column (38) drives the fixed rod (36) and the lever (37) to rotate through the synchronous wheel and the synchronous belt. The lever (37) is disengaged from the U-shaped handle (20). Then, the rotating column (38) drives the connecting plate (35) and the fixed rod (36) to rise and fall to a position above the storage box (2) of the fruits and vegetables to be taken out. The rotating column (38) is reset and rotated under the action of the torsion spring (39). The lever (37) is inserted into the corresponding U-shaped handle (20). Then, the lever (37) is electrically driven to move the connecting plate (35) and the fixed rod (36). The machine drives the threaded rod (43) to rotate, driving the top plate (3) and the plurality of storage boxes (2) above the storage box (2) for fruits and vegetables to be taken out to move upward, so that the corresponding storage box (2) can be taken out, and after taking out, the threaded rod (43) rotates in the opposite direction to stack the plurality of storage boxes (2) again to continue storage, and after taking out the corresponding storage box (2), the overall height of the device is reduced, reducing the space occupancy rate, and after the corresponding storage box (2) is taken out, the space for arranging cold air and water mist in the storage box (2) is also reduced, avoiding waste of air and water mist; S5.

The lead screw (46) drives the sealing ring (44) to move up and down, and then the shielding area of the first through hole (7) by the sealing ring (44) can be controlled, thereby completing the control of the amount of air and water mist entering the storage box (2).
