[0004] The above technical solution still has the following deficiencies during use: 1. The above technical solution stores fruits and vegetables through the box body. When the corresponding box body is pulled out and the corresponding fruits and vegetables are taken out, the device will reduce the storage amount of fruits and vegetables while the space occupied will not be reduced. Therefore, as the fruits and vegetables are continuously taken out, the device still occupies a large amount of space, affecting the storage of other fruits and vegetables in the later stage; 2. When the box 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 being unable to be effectively utilized.

[0015] In a possible design, a closed ring for closing the first through hole is slidably connected in the fixed column, and a connecting ear is fixed to an inner wall of one side of the closed ring, and a screw rod is passed through the inner thread of the connecting ear, and the cooperation between the screw rod and the connecting ear is used to control the lifting of the closed ring, and the bottom end of the screw rod rotates to extend into the liquid collecting tank and is rotatably connected to the bottom inner wall of the liquid collecting tank, and the outer wall fixed sleeve of the screw rod is provided with a first bevel gear, and a driving rod is rotatably connected in the liquid collecting tank through the base, and one end of the driving rod is fixed with a second bevel gear meshing with the first bevel gear, and the other end of the driving rod rotates to extend 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 in the fixed column entering the storage box, so as to control the temperature and humidity in the storage box, the screw rod is driven to rotate by rotating the driving rod, and the screw rod drives the closed ring to rise and fall, thereby being able to control the blocking area of ​​the closed ring to the first through hole, thereby completing the amount of air and water mist entering the storage box.

[0016] In the present application, a method for using a storage device for agricultural products and fruits and vegetables with precise temperature and humidity control and classifiable properties comprises the following steps: S1. According to the number of fruits and vegetables stored in the storage box, the distance between two adjacent baffles can be adjusted by rotating the baffles, 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 bottom plate. The threaded rod is driven by a motor to rotate, and the threaded rod drives the top plate to move down and close the top storage box. 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; 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; 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. 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.

[0017] Beneficial effects: In the present invention, the material-taking structure comprises two fixed rods penetrating the top plate, the outer walls of the two fixed rods are fixedly sleeved with levers, 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 threadedly connected to the threaded cylinder, and the top end of the threaded rod is rotatably connected to the bottom of the top plate; the control cavity is rotated to drive the lever to disengage from the U-shaped handle, and then the connecting plate and the fixed rod are driven to rise and fall to corresponding positions through the rotating column, and then the lever is clamped with the U-shaped handle again, and the top plate and the storage box are driven to move up through the cooperation of the motor and the threaded rod, so that the corresponding storage box can be taken out, and after taking it out, storage can continue, and after taking out the corresponding storage box, the overall height of the device is reduced, reducing the space occupancy rate; In the present invention, the fixing column is fixed with a first magnet through a connecting frame, the bottom inner wall of the top plate is fixed with a second conduit, the bottom inner wall of the fixing column is fixed with a first conduit, the first conduit and the second conduit are both fixed with a fixing ring, the top of the fixing ring is slid with a closing plate through a guide rod, and the bottom of the closing plate is fixed with a second magnet; a repulsive force is generated between the second magnet and the adjacent first magnet, thereby releasing the sealing of the first conduit and the second conduit, allowing air and water mist to enter the storage box in turn, completing the temperature and humidity control of fruits and vegetables, and in addition, after one of the storage boxes is taken out, the space for arranging cold air and water mist in the storage box is reduced, avoiding the waste of air and water mist; In the present invention, a closed ring is slidably connected in the fixed column, and a screw rod is penetrated through the inner wall of one side of the closed ring through a connecting ear thread. The bottom end of the screw rod rotates and extends into the liquid collecting tank. A driving rod is rotatably connected in the liquid collecting tank through the base, and the screw rod and the liquid guiding tube are meshed through the first bevel gear and the second bevel gear. The screw rod is driven to rotate by rotating the driving rod, and the screw rod drives the closed ring to rise and fall, thereby controlling the shielding area of ​​the closed ring to the first through hole, thereby completing the amount of air and water mist entering the storage box, thereby controlling the temperature and humidity in the storage box.

[0018] In the present invention, pairs of storage boxes can be flexibly stacked to complete the storage of fruits and vegetables, and after taking out any storage box, multiple storage boxes can still complete the storage operation, and their height can also be reduced to save space. In addition, as the number of storage boxes is reduced, the space for air and water mist to diffuse can be reduced, and the air and water mist can be fully utilized to avoid waste of air and water mist.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1 and Figure 2 , a storage device, relates to the field of storage technology, the device comprises a chassis 1, and a top plate 3 is provided 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 the two fixed cylinders 40, and the sliding rods 41 can slide stably in the fixed cylinders 40. The top ends 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 stably raised and lowered. 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 classified storage of agricultural products, fruits and vegetables, and the structures of the plurality of storage boxes 2 are the same.

[0023] Reference Figure 8 and Fig. 9In 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 and the control chamber 28 are connected by a hose 27. The bottom inner wall of the recovery tank 23 is fixed with an atomizer 26 by bolts, and 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 plate 31 and a cooling plate 32 by bolts, and the carbon resistance wire heating plate 31 can heat the air in the control chamber 28, and the cooling plate 32 can cool the air in the control chamber 28. Two circular holes are provided on the top of the top plate 3, and the circular holes are connected with the control chamber 28. Fans 30 are fixed in both circular holes by bolts, and the fan 30 can discharge the outside air into the control chamber 28.

[0024] When in use, the carbon resistance wire heating sheet 31, the cooling sheet 32 ​​and the fan 30 are started as needed, and the fan 30 injects the outside air into the control chamber 28, and the carbon resistance wire heating sheet 31 and the cooling sheet 32 ​​heat and cool the air as needed, 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 fixed 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, and 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 guide tube 34 and multiple fixed columns 4 to control the humidity in the storage box 2.

[0025] Reference Figure 3-Figure 9In 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 wall of the bottom of the storage box 2, a connection hole 8 is provided on the top of the fixed column 4, a connecting frame 10 is welded in the connecting hole 8, and a first magnet 9 is welded on the top of the connecting frame 10. A second conduit 34 is welded to the inner wall of the bottom of the top plate 3, a first conduit 11 is welded through the inner wall of the bottom 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 connecting hole 8 and the second conduit 34, so that air and water mist can flow through the multiple storage boxes 2 and the control cavity 28 between them. A fixing ring 12 is welded inside the first conduit 11 and the second conduit 34, and a plurality of guide rods 13 are welded on the top of the fixing ring 12. The outer wall of the plurality of guide rods 13 is 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 sealing of the corresponding first conduit 11 and the second conduit 34 by the fixing ring 12 and the closing plate 14. The outer wall of the fixing column 4 is provided with a plurality of first through holes 7 for allowing air and water mist to enter the storage box 2.

[0026] Specifically, after multiple storage boxes 2 are stacked and the top plate 3 is placed on the top of the topmost 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 closure of the first duct 11 and the second duct 34, allowing air and water mist to enter the storage box 2 in turn, completing the temperature and humidity control of fruits and vegetables.

[0027] Reference Figure 2 , Figure 8 and Fig.10In order to realize the convenient access and placement of the storage box 2, the device is provided with a material-retrieving structure. The material-retrieving structure includes two fixed rods 36 respectively passing through the two sides of the top plate 3, and the two fixed rods 36 are connected together above the top plate 3 by a connecting plate 35. A rotating column 38 is rotated through the connecting plate 35, and the rotating column 38 and the two fixed rods 36 are connected by a synchronous wheel and a synchronous belt. In other words, when the rotating column 38 rotates, it will drive the two fixed rods 36 to rotate synchronously. In order to ensure that the rotating column 38 can maintain a specific position when not subject to external force, we set a torsion spring 39 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 the 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 reset the rotating column 38. On the outer walls of the two fixed rods 36, we respectively set a lever 37 fixedly. At the same time, U-shaped handles 20 are fixed on both sides of the storage box 2. These U-shaped handles 20 are designed to engage with the lever 37, thereby achieving the engagement between the storage box 2 and the material extraction structure.

[0028] Reference Figure 8 In order to realize the lifting and lowering of the top plate 3 and the storage box 2, we fixed a threaded cylinder 42 on the top of the bottom plate 1, and 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 a motor is set in the top plate 3. The output shaft of the motor is connected to the top end of the threaded rod 43 to drive the threaded rod 43 to rotate in the threaded cylinder 42. When the threaded rod 43 rotates, the top plate 3 and the storage box 2 on the top plate 3 will be driven to rise or fall together.

[0029] Specifically, when we need to take out a storage box 2, we first rotate the rotating column 38 by external force, and the rotating column 38 drives the two fixed rods 36 and the lever 37 to rotate through the synchronous wheel and the synchronous belt, so that the lever 37 is disengaged from the U-shaped handle 20. Then, the connecting plate 35 and the fixed rod 36 are driven to rise and fall to the position above the storage box 2 of the fruits and vegetables to be taken out by the rotating column 38. At this time, the external force is released, and the rotating column 38 is reset and rotated under the action of the torsion spring 39, and the lever 37 is inserted into the corresponding U-shaped handle 20. Next, the threaded rod 43 is driven to rotate by the motor, and the threaded rod 43 drives the top plate 3 and the multiple storage boxes 2 above the storage box 2 of the fruits and vegetables to be taken out to move up together through the cooperation of the threaded cylinder 42, so that the corresponding storage box 2 can be taken out. After taking out, the threaded rod 43 is driven to rotate in the reverse direction by the motor, and the multiple storage boxes 2 are stacked again to continue storage. In this way, after taking out the corresponding storage box 2, the overall height of the device is reduced, which reduces the occupancy rate of the space.

[0030] Reference Figure 3 and Figure 4In addition, we also rotatably sleeve a plurality of 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 baffles 5, we can control the size of the storage space to meet the storage needs of agricultural products or fruits and vegetables of different sizes. On one side of one of the baffles 5, we fixedly embedded a temperature and humidity sensor 6 for real-time monitoring of the temperature and humidity in the storage box 2 to ensure that the agricultural products or fruits and vegetables can be stored under suitable temperature and humidity conditions.

[0031] Reference Figure 3 and Figure 8 In order to facilitate 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, in the recovery slot 23, we fixed a partition 24, and fixed an activated carbon layer 25 in the partition 24. The activated carbon layer 25 is designed to filter water, so that the atomizer 26 can atomize water later, and provide a suitable humidity environment for the agricultural products or fruits and vegetables in the storage box 2.

[0032] Reference Fig. 9 An air filter 29 is provided in the control chamber 28. The air filter 29 is fixed in the circular hole, and its function is to filter the air entering the control chamber 28 to remove pollutants such as dust and impurities. At the same time, a plurality of ultraviolet sterilization lamps 33 are fixed on the inner wall at the bottom of the control chamber 28. These ultraviolet sterilization lamps 33 can emit ultraviolet rays to sterilize the air in the control chamber 28, thereby further purifying the air and providing a cleaner storage environment for agricultural products and fruits and vegetables.

[0033] Reference 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.

[0034] 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.

[0035] Example 2: Reference Fig.11 and Fig.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.

[0036] 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.

[0037] A method for using a temperature and humidity precise control and classifiable agricultural product fruit and vegetable storage device, comprising the following steps: 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. 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; 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; S4, when it is necessary to take out the fruits and vegetables in the corresponding storage box 2, the rotating column 38 is rotated, and the rotating column 38 drives the fixed rod 36 and the lever 37 to rotate through the synchronous wheel and the synchronous belt, and the lever 37 is disengaged from the U-shaped handle 20, and then the connecting plate 35 and the fixed rod 36 are driven to rise and fall to the position above the storage box 2 for fruits and vegetables to be taken out through the rotating column 38, and the rotating column 38 is reset and rotated under the action of the torsion spring 39, and the lever 37 is inserted into the corresponding U-shaped handle 20, and then the threaded rod 43 is driven by the motor to rotate, and the top plate 3 and the multiple storage boxes 2 above the storage box 2 for fruits and vegetables to be taken out are driven 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, and the multiple storage boxes 2 are stacked again to continue storage, and after taking out the corresponding storage box 2, the overall height of the device is reduced, and the space occupancy rate is reduced, and after the corresponding storage box 2 is taken out, the space for cold air and water mist to be arranged in the storage box 2 is also reduced, so as to avoid waste of air and water mist; S5. When it is necessary to control the amount of air and water mist in the fixed column 4 entering the storage box 2 so as to control the temperature and humidity in the storage box 2, the drive rod 48 is rotated to drive the screw rod 46 to rotate in cooperation with the first bevel gear 47 and the second bevel gear 49. The screw rod 46 drives the closed ring 44 to rise and fall, thereby controlling the blocking area of ​​the closed ring 44 on the first through hole 7, thereby completing the amount of air and water mist entering the storage box 2.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the carbon wire heating plate 31, the cooling plate 32, the ultraviolet sterilization lamp 33, the fan 30, the temperature and humidity sensor 6 and the atomizer 26 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
