[0032] According to an optional embodiment of the present invention, the floating block 28 is made of PE, which has a low density, is water-resistant and non-toxic.

[0033] According to an optional embodiment of the present invention, a processing module is provided in the housing 1. The processing module is used for data analysis and component control.

[0034] According to an optional embodiment of the present invention, a temperature sensor is embedded in the inner wall of the fresh-keeping cavity 2. The temperature sensor is used to obtain temperature data in real time. The temperature sensor and the refrigeration device 4 are electrically connected to the processing module respectively.

[0035] According to an optional embodiment of the present invention, a friction layer 12 is fixedly connected to the bottom wall of the box body 1. The friction layer 12 prevents the box body 1 from sliding, and the friction layer 12 can be made of silicone or sponge.

[0036] Implementation process:

[0037] Open the cover 3, add cold water 5 into the fresh-keeping cavity 2, and then place the bag 6 packed with litchi in the cold water 5. The bag 6 can effectively block water evaporation, reduce the rate of water loss from the litchi skin, prevent the skin from drying and browning, thereby prolonging the freshness and taste of the fruit. The cold water 5 can reduce the ambient temperature of the litchi, inhibit the respiration and metabolic activities of the litchi, delay the aging and corruption of the fruit, inhibit the oxidation process of the litchi, keep the skin red, and keep the freshness of the litchi better than ordinary refrigeration. In addition, the cold water 5 can provide a good buffering and shock-absorbing effect on the litchi when it is bumpy during transportation, preventing the litchi from being damaged by bumps.

[0038] Then close the cover body 3, insert the limiting wedge block 42 and the fixing block 43 on one of the boxes 1 into the connecting channel 31 and the connecting cavity 30 of the other box 1, the inclined surface of the limiting wedge block 42 pushes the inclined surface of the sliding wedge block 36, and the sliding wedge block 36 overcomes the magnetic repulsion of the third permanent magnet block 34 and moves upward, after the limiting wedge block 42 moves to the left of the sliding wedge block 36, the sliding wedge block 36 moves downward and resets under the magnetic repulsion of the third permanent magnet block 34, thereby limiting the limiting wedge block 42, completing the connection and fixation between adjacent boxes 1, preventing relative movement between adjacent boxes 1, and improving transportation stability.

[0039] When bumps occur during transportation, the mass ball 9 will swing left and right. When the mass ball 9 swings to the right, it will push the slider 10 and the push bar 11 to overcome the elastic force of the first elastic member 26 and move to the right. The push bar 11 pushes one of the permanent magnets 14 to rotate until one end of a permanent magnet 14 on the left side of the permanent magnet 14 abuts against the bottom wall of the push bar 11, thereby causing the rotating column 13, the first transmission wheel 16, the transmission belt 17, the first gear 19, and the second transmission wheel 18 to rotate clockwise, and the first gear 19 drives the second gear 20 and the extension rod 2 1. The linkage rod 22 rotates counterclockwise by a small angle. When the mass ball 9 swings to the left, the mass ball 9 separates from the slider 10. The slider 10 moves left and resets under the elastic force of the first elastic member 26. Then the magnetic force of the fixed permanent magnet block 15 magnetically attracts a permanent magnet piece 14 closest to the fixed permanent magnet block 15, so that the permanent magnet piece 14 rotates clockwise and becomes vertical. The permanent magnet piece 14 that was previously against the bottom wall of the push bar 11 also rotates clockwise and becomes vertical, so that it can be pushed by the push bar 11 later.

[0040] The mass ball 9 swings back and forth, so that the push bar 11 pushes different permanent magnet sheets 14, so that the linkage rod 22 rotates intermittently. When the linkage rod 22 rotates, it will drive the linkage frame 23 to move back and forth intermittently up and down. After the linkage frame 23 moves up, the bag 6 will be deformed, and the cold water 5 will increase the contact area with the outer wall of the bag 6. At the same time, the lychees in the middle of the bag 6 will move closer to the left and right sides of the bag 6, so that more cold energy is transferred to the lychees originally in the middle of the bag 6, thereby improving the uniformity of cooling the lychees and preventing the lychees originally in the middle of the bag 6 from being insufficiently cooled, resulting in a decrease in the preservation effect. After the top rod 25 descends, the bag 6 will return to a shape close to its original shape, and the position of the lychees in the bag 6 will change, preventing the lychees from staying in the same position for too long, thereby improving the uniformity of cooling the lychees.

[0041] The temperature sensor can obtain the temperature of the cold water 5 in real time, so that the processing module can control the working state of the refrigeration device 4 in real time to control the temperature of the cold water 5 within a suitable range.

[0042] When it is necessary to release the connection between adjacent boxes 1, it is only necessary to take out the bag 6, the liquid level of the cold water 5 drops, the floating block 28 and the first permanent magnet block 29 move down, the first permanent magnet block 29 moves down to below the thin plate 41, and the second permanent magnet block 33 loses the magnetic attraction of the first permanent magnet block 29. The second permanent magnet block 33, the connecting block 32, and the third permanent magnet block 34 move right under the elastic force of the second elastic member 35, and the fourth permanent magnet 37 loses the magnetic repulsion of the third permanent magnet block 34. The sliding wedge block 36, the fourth permanent magnet 37, and the sliding plate 38 move upward under the elastic force of the third elastic member 39, and the limiting wedge block 42 can be moved right to make the limiting wedge block 42 and the fixed block 43 disengage from the connecting cavity 30, thereby completing the disconnection of the two adjacent boxes 1, which is convenient and quick, and does not require the aid of other tools.

[0043] The present invention can utilize the bag 6 and cold water 5 to realize the functions of refrigerating, preserving and locking water for litchi, delaying the aging and corruption of litchi fruits, inhibiting the oxidation process of litchi, keeping the peel rosy, and maintaining the freshness of litchi better than ordinary refrigeration; the power generated during transportation bumps causes the mass ball 9 to swing, so that the top rod 25 slowly moves up and down through a series of linkages, thereby improving the uniformity of cooling of the litchi in the bag 6, preventing some litchi from not being effectively refrigerated and resulting in a decrease in the freshness-preserving effect, and better maintaining the quality of the litchi.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
