[0021] Example

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a built-in atmosphere-controlled fresh-keeping container device includes a container 1, a mounting cavity is arranged on the left side of the container 1, an inert gas box 3 is arranged inside the mounting cavity, an injection pipe 6 is arranged on the upper inner wall of the right side of the container 1, and a plurality of nozzles 601 are evenly arranged on the injection pipe 6. The injection pipe 6 is connected to the inert gas box 3 through a connecting pipe 4, and an air pump 5 is also arranged on the connecting pipe 4. When it is necessary to transport products such as fruits and vegetables for a long time, the air pump 5 pumps the inert gas in the inert gas box 3 into the injection pipe 6 through the connecting pipe 4, and then the injection pipe 6 is used to inject the inert gas into the inert gas box 3. The nozzle 601 on the pipe 6 sprays out, thereby spraying the inert gas into the interior of the container 1, thereby inhibiting the reproduction of microorganisms in the container 1, thereby ensuring the container 1 for long-term transportation of fruits and vegetables. The container 1 is also provided with an exhaust pipe, and the exhaust pipe is provided with a one-way valve 7. When the jet pipe 6 sprays the inert gas into the interior of the container 1, the inert gas sinks and squeezes the air upward, and the air is discharged through the exhaust pipe. Under the action of the one-way valve 7, the occurrence of gas reflux can be reduced, thereby ensuring the protection efficiency of the inert gas for fruits and vegetables.

[0023] A slide groove 8 is also provided on the inner wall at the lower right side of the container 1, and a slider 9 is slidably provided in the slide groove 8. A placement plate 10 is provided on the top of the slider 9. Under the action of the slide groove 8 and the slider 9, the placement plate 10 can be driven to move, thereby facilitating the staff to load and unload goods. A threaded rod 11 is also rotatably provided in the slide groove 8, and the threaded rod 11 passes through the slider 9 and is threadedly connected with the slider 9. At this time, rotating the threaded rod 11 can drive the slider 9 to move in the slide groove 8, thereby pushing the placement plate 10 out of the container 1. A rotating shaft 12 is also rotatably provided below the inert gas box 3 in the installation cavity, and a second bevel gear 14 is provided on the rotating shaft 12 through a key connection. A first bevel gear 13 is provided on the threaded rod 11 inside the installation cavity through a key connection. The first bevel gear 13 and the second bevel gear 14 are meshed with each other. At this time, rotating the rotating shaft 12 The threaded rod 11 can be driven to rotate by the second bevel gear 14 and the first bevel gear 13, so that the placement plate 10 can be pushed out from the inside of the container 1. A worm gear 15 is also provided on the rotating shaft 12 above the second bevel gear 14 through a key connection. A worm 16 is also rotatably provided inside the installation cavity. The worm 16 and the worm gear 15 are meshed with each other. At this time, rotating the worm 16 can drive the rotating shaft 12 to rotate through the worm gear 15, thereby driving the threaded rod 11 to rotate. In addition, because the worm gear 15 and the worm 16 have a self-locking function, the adjusted position of the placement plate 10 is limited, which makes it more convenient for the staff to load and unload goods. A motor 1601 is also provided inside the installation cavity. The power output shaft of the motor 1601 is connected to the worm 16 through a coupling. The worm gear 15 can be driven to rotate by the worm 16 using the motor 1601.

[0024] A heat dissipation hole is also provided on the upper wall of the container 1 above the installation cavity. A heat dissipation fan 18 is provided in the heat dissipation hole through a bracket 17. A heat dissipation mesh plate 19 is also provided on the heat dissipation hole. Under the action of the heat dissipation fan 18, the heat generated by the motor 1601 and the air pump 5 inside the installation cavity when they are working can be discharged, thereby reducing the impact of the excessive temperature inside the installation cavity on the container 1. Bumpers 101 are provided at the bottom and bottom of the container 1. Under the action of the bumpers 101, when the container 1 is stored, there is a certain gap between the containers 1 and 1, thereby facilitating the loading and unloading of the container 1.

[0025] A door 21 is also provided on the right side of the container 1 via a connecting rod 20 , and the airtightness of the container 1 is ensured by the door 21 .

[0026] In actual use, after the goods that need to be kept fresh are loaded, the air pump 5 is started to extract the inert gas from the inert gas box 3 and introduce it into the injection pipe 6 through the connecting pipe 4, and then sprayed out by the nozzle 601, so that the interior of the container 1 is filled with inert gas. With the injection of inert gas, the air inside the container 1 is gradually squeezed and moves upward, and the air is discharged through the exhaust pipe. Under the action of the one-way valve 7, the inert gas is prevented from flowing back. When it is necessary to load and unload goods, the motor 1601 can be started to drive the worm 16 to rotate through the worm gear 15, the rotating shaft 12, the first bevel gear 13 and the second bevel gear 14 to drive the threaded rod 11 to rotate, so that the slider 9 moves in the slide groove 8, and then the placement plate 10 is moved out of the container 1, so as to facilitate the loading and unloading of goods. In addition, because the motor 1601 and the air pump 5 will generate a certain amount of heat when working, the heat dissipation fan 18 can be used to discharge the generated heat.
