[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a lychee preservation device includes a cabinet 11, with a cabinet door 12 hinged to the side of the cabinet 11 and a latch installed between the cabinet door 12 and the cabinet 11; multiple pairs of guide rails 14 are fixedly connected to the inner wall of the cabinet 11; a water tank 15 is installed at the bottom of the cabinet 11, and a heat exchange pipe 17 is installed inside the water tank 15. The heat exchange pipe 17 has a U-shaped structure. A fan 16 is installed on the side of the water tank 15, and the air inlet of the fan 16 is fixedly connected to the heat exchange pipe 17; multiple casters 13 are installed at the bottom of the cabinet 11; an air guide plate 21 is installed on the inner wall of the cabinet 11, and a cold air flow channel 22 is formed between the air guide plate 21 and the inner wall of the cabinet 11; multiple through slots 23 are opened on the side of the air guide plate 21; and the air outlet of the fan 16 is connected to the cold air flow channel 22.

[0024] During use, the bottom of the cabinet 11 is equipped with casters 13 for easy transport. The guide rails 14 inside the cabinet 11 are used for layering the lychee mesh frames. The water tank 15 is used to store an ice-water mixture. Then, the heat exchange tubes 17 are inserted into the water tank 15. The fan 16 drives the airflow to pass through the heat exchange tubes 17, thereby facilitating the cooling of the air and improving the heat exchange effect. With the above structure, it is possible to facilitate the low-temperature storage of lychees during temporary transport. The use of an ice-water mixture for cooling reduces the power requirements of the compressor. The fan 16 is powered by an external battery module or a 5V / 12V DC fan 16. During use, multiple air guide plates 21 are installed on the inner side wall of the cabinet 11. The cold air blown out by the fan 16 enters the cold air flow channel 22 connected to the air outlet, flows in the cold air flow channel 22, and is then blown out from the through slot 23, thereby improving the uniformity of cold air distribution and facilitating the cooling of the lychee mesh frames located above.

[0025] Furthermore, such as Figure 1-5 As shown, a partition 6 is installed inside the water tank 15, which separates the medicine chamber 62 and the cooling chamber 61. The heat exchange tube 17 is located inside the cooling chamber 61. A submersible pump 31 is installed inside the medicine chamber 62. A delivery pipe 32 is installed at the outlet of the submersible pump 31. Multiple atomizing nozzles 33 are installed on the delivery pipe 32, and the atomizing nozzles 33 are located on the side of the guide rail 14. A water receiving plate 4 is hinged to the top of the water tank 15. The water receiving plate 4 is inclined, and the bottom of the water receiving plate 4 is located above the medicine chamber 62.

[0026] During use, the medicine chamber 62 stores antibacterial agent, which is then drawn out by the submersible pump 31 and delivered to multiple atomizing nozzles 33 via the delivery pipe 32. The atomizing nozzles 33 spray the medicine mist into the inside of the lychee mesh frame. The antibacterial agent can inhibit bacterial growth, extend shelf life, and facilitate use. A water receiving plate 4 is fixed to the bottom of the cabinet 11. The water receiving plate 4 is inclined and guides the collected medicine back into the medicine chamber 62. The hinged water receiving plate 4 can be rotated upwards to open. The submersible pump 31 is a 23W SUNSUN XQP-1500 submersible pump 31, the fan 16 is a waterproof fan 16, and the heat exchange tube 17 is a metal tube.

[0027] Furthermore, such as Figure 1-5 As shown, a plurality of fins 5 are fixed to the surface of the heat exchange tube 17, and the plurality of fins 5 are evenly distributed along the surface of the heat exchange tube 17. The fins 5 are located inside the cooling chamber 61. The partition 6 is a metal plate and is arranged in a corrugated structure.

[0028] During use, multiple fins 5 are uniformly fixed on the heat exchange tube 17. The fins 5 are located inside the cooling chamber 61 and come into contact with ice water for continuous cooling. The partition 6 is a metal plate, which is used for mixed heat transfer between the cooling chamber 61 and the medicine chamber 62 to achieve continuous cooling.

[0029] Furthermore, such as Figure 1-5 As shown, the interior of the cabinet 11 is filled with an insulating board, and a battery module is installed on the cabinet 11. The battery module is used to power the diving mask and the fan 16 inside, and the insulating board is used for heat insulation of the cabinet 11.

[0030] Working principle: During use, the bottom of the cabinet 11 is equipped with casters 13 for easy transportation. The guide rails 14 inside the cabinet 11 are used for layered installation of the lychee mesh frame. The water tank 15 is used to store the ice-water mixture. Then, the heat exchange tube 17 is inserted into the water tank 15. The fan 16 drives the airflow to move, and the airflow passes through the heat exchange tube 17 to facilitate cooling of the air and improve the heat exchange effect. With the above structure, it is possible to facilitate the low-temperature storage of lychees during temporary transportation. The ice-water mixture is used for cooling, which reduces the power supply requirements of the compressor. The fan 16 is powered by an external battery module or a 5V / 12V DC fan 16 can be selected.

[0031] During use, multiple air guide plates 21 are installed on the inner wall of the cabinet 11. The cold air blown out by the fan 16 enters the cold air flow channel 22 connected to the air outlet, flows within the cold air flow channel 22, and is then blown out from the through groove 23. This improves the uniformity of cold air distribution and facilitates cooling of the lychee net frame located above. During use, the medicine chamber 62 stores antibacterial agent, which is then drawn out by the submersible pump 31 and delivered to multiple atomizing nozzles 33 via the delivery pipe 32. The atomizing nozzles 33 spray the medicine mist into the lychee net frame. The antibacterial agent inhibits bacterial growth, extends shelf life, and facilitates use. A water receiving plate 4 is fixed to the bottom of the cabinet 11. The water receiving plate 4 is inclined and guides the collected medicine back into the medicine chamber 62. The hinged water receiving plate 4 can be rotated upwards to open. The submersible pump 31 is a 23W SUNSUN pump. The XQP-1500 submersible pump 31 uses a waterproof fan 16, and the heat exchange tube 17 is a metal tube. During use, multiple fins 5 are evenly fixed on the heat exchange tube 17. The fins 5 are located inside the cooling chamber 61 and come into contact with ice water for continuous cooling. The partition 6 is a metal plate, which is used for mixed heat transfer between the cooling chamber 61 and the medicine chamber 62 to achieve continuous cooling.
