[0032] Reference Figure 1-4 , an air circulation cold storage, is used for constant temperature and humidity storage of goods. In order to facilitate the ventilation of the cold storage, avoid the accumulation of harmful gases, and prevent the entry of external hot air when materials are in and out.

[0033] The air circulation cold storage comprises a cold storage body 1, a refrigeration box 2, a rotating drum 6 and a fixed box 3;

[0034] The wall of the cold storage body 1 is provided with insulation material, the refrigeration box 2 is arranged inside the cold storage body 1, and the inside of the refrigeration box 2 is provided with a refrigerator 5 and a fan, the refrigerator 5 is an evaporative condenser, and an air compressor is provided outside the cold storage body 1. The air compressor is connected to the refrigerator 5 to provide refrigerant to the refrigerator 5, so that under the action of the fan, the refrigeration box 2 blows out cold air to cool the inside of the cold storage body 1.

[0035] An openable cold storage door 101 and an installation port are provided on one side wall of the cold storage body 1. The installation port is located above the cold storage door 101. The fixed box 3 is fixed inside the installation port, and the sealing of the connection between the fixed box 3 and the cold storage body 1 must be ensured. Since the fixed box 3 is arranged inside the installation port, one end of the fixed box 3 is located inside the cold storage body 1, and the other end is located outside the cold storage body 1. The fixed box 3 is provided with a first through hole 301 and a fourth through hole 304 on one side located outside the cold storage body 1, and a second through hole 302 and a third through hole 303 on one side located inside the cold storage body 1. The first through hole 301 and the second through hole 302 are respectively located on both sides of the bottom surface of the fixed box 3, and the third through hole 303 and the fourth through hole 304 are respectively located on the top of the two side surfaces of the fixed box 3. The fixed box 3 is rotatably connected to the inside with a rotating plate 4. When the rotating plate 4 is rotated to a horizontal state, the fixed box 3 can be The first through hole 301 and the second through hole 302 are connected, and the third through hole 303 and the fourth through hole 304 are connected. At this time, since the external air can enter the fixed box 3 through the first through hole 301, and then enter the refrigerating box 2 through the second through hole 302 connected to the refrigerating box 2 for cooling, the cold air enters the cold storage body 1, and the gas inside the cold storage body 1 will be discharged through the third through hole 303 and the fourth through hole 304 in turn, so as to avoid the accumulation of harmful gases inside the cold storage body 1. When the rotating plate 4 rotates to a vertical state, the second through hole 302 and the third through hole 303 are connected. Therefore, at this time, the air inside the cold storage body 1 will enter the fixed box 3 through the third through hole 303, and then enter the refrigerating box 2 through the second through hole 302 for cooling, so that the cold air circulates into the cold storage body 1 to ensure the storage temperature inside the cold storage body 1.

[0036] Since the rubber strips 8 are fixedly connected to the inner walls of the four sides of the fixed box 3, the ends of the rotating plate 4 are arc-shaped, and the ends of the rotating plate 4 are adapted to the rubber strips 8, so that when the rotating plate 4 is rotated to a horizontal state or a vertical state, its ends are in close contact with the rubber strips 8, thereby ensuring the sealing and facilitating air flow, and a first rotating shaft 401 and a first servo motor are provided inside the fixed box 3, the output shaft of the first servo motor is connected to the first rotating shaft 401, and the first rotating shaft 401 is connected to the rotating plate 4, so that the rotation of the rotating plate 4 can be controlled by the first servo motor, so that the cold storage is ventilated with the outside or the air inside the cold storage is circulated. When the cold storage is ventilated with the outside, since the fixed box 3 is provided with a filter 9 at the first through hole 301, the external air will first be filtered by the filter 9 and then enter the inside of the cold storage body 1, thereby preventing foreign matter such as dust from entering the cold storage body 1.

[0037] A second rotating shaft 601 and a second servo motor are provided at the outlet of the refrigerating box 2. The output shaft of the second servo motor is connected to the second rotating shaft 601. The second rotating shaft 601 is connected to the rotating drum 6, so that the second servo motor drives the rotating drum 6 to rotate. A strip opening is provided on the rotating drum 6 and is connected to the refrigerating box 2. The rotating drum 6 is provided with an air guide port 602 at the air outlet. The cold air inside the refrigerating box 2 can enter the rotating drum 6 through the strip opening and be ejected through the air guide port 602. Since the rotating drum 6 is located above the cold storage door 101, when the second servo motor drives the rotating drum 6 to rotate, the air guide port 602 can be made to face downward to the cold storage door 101. At this time, when the cold storage door 101 is opened for loading and unloading, the air flows downward to form a wind curtain, thereby effectively preventing external hot air from entering the cold storage body 1. After the cold storage door 101 is closed, the rotating drum 6 can be driven to rotate by the second servo motor so that the air guide port 602 faces the center position of the cold storage body 1, so that the cold air covers the materials, which is convenient for the storage of materials.

[0038] In addition, in order to facilitate the air circulation inside the cold storage body 1, an exhaust pipe 7 is provided at the internal top of the cold storage body 1, and a plurality of exhaust ports 701 are arranged at the bottom of the exhaust pipe 7. One end of the exhaust pipe 7 is connected to the third through hole 303. The air inside the cold storage body 1 will be sucked in through the plurality of exhaust ports 701 and then enter the fixed box 3. The plurality of exhaust ports 701 are provided so that the air at various positions inside the cold storage body 1 can evenly enter the exhaust pipe 7, thereby facilitating the overall circulation of the air inside the cold storage body 1.

[0039] The working principle of the air circulation cold storage:

[0040] When the cold storage needs to be connected to the outside for ventilation, the first servo motor drives the first rotating shaft 401 to rotate, thereby controlling the rotating plate 4 to rotate to a horizontal state, and the rotating plate 4 divides the fixed box 3 into two upper and lower spaces. At this time, the first through hole 301 and the second through hole 302 are connected, and the third through hole 303 is connected with the fourth through hole 304. External air enters the lower space of the fixed box 3 through the first through hole 301, and then enters the refrigeration box 2 through the second through hole 302 connected to the refrigeration box 2, and is cooled by the refrigerator 5 inside the refrigeration box 2. Then, the cold air is allowed to enter the rotating cylinder 6 through the fan, and finally, the cold air enters the cold storage body 1 through the air guide port 602, and the gas inside the cold storage body 1 will enter the exhaust cylinder 7 through multiple exhaust ports 701, and then enter the upper space of the fixed box 3 through the third through hole 303, and finally be discharged to the outside through the fourth through hole 304, thereby avoiding the accumulation of harmful gases inside the cold storage body 1;

[0041] When the cold storage performs air circulation, the first servo motor drives the first rotating shaft 401 to rotate, thereby controlling the rotating plate 4 to rotate to a vertical state, and the rotating plate 4 divides the fixed box 3 into two spaces on the left and right, and the second through hole 302 is connected to the third through hole 303. At this time, the air inside the cold storage body 1 will enter the exhaust cylinder 7 through the multiple air suction ports 701, and then enter the left space of the fixed box 3 through the third through hole 303, and then enter the refrigeration box 2 through the second through hole 302 for cooling, and then the cold air is allowed to enter the rotating cylinder 6 through the fan, and finally the cold air enters the cold storage body 1 through the air guide port 602, so that the cold air circulates into the cold storage body 1 to ensure the storage temperature inside the cold storage body 1;

[0042] When the goods are in and out of the warehouse, since the rotating cylinder 6 is located above the cold storage door 101, the second rotating shaft 601 is rotated by the second servo motor, and the second rotating shaft 601 drives the rotating cylinder 6 to rotate, so that the air guide port 602 is downward toward the cold storage door 101. At this time, when the cold storage door 101 is opened to enter and exit the goods, the air flows downward to form an air curtain, thereby effectively preventing external hot air from entering the cold storage body 1. After the cold storage door 101 is closed, the rotating cylinder 6 can be driven by the second servo motor to rotate, so that the air guide port 602 is toward the center of the cold storage body 1, so that the cold air covers the materials, which is convenient for the storage of materials.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
