Description

Technical Field

[0001] The utility model relates to the technical field of litchi freezing and fresh-keeping boxes, in particular to a litchi freezing and fresh-keeping box capable of adjusting humidity. Background Art

[0002] During frozen transportation, lychees are usually stored and transported in fresh-keeping boxes. The fresh-keeping boxes can prevent moisture from escaping and act as a seal to prevent lychees from losing their original flavor during storage. At the same time, they can isolate the air and prevent lychees from oxidation.

[0003] In the prior art, during frozen transportation of lychees, the fresh-keeping boxes used are relatively simple in structure and only have a storage function. During transportation and storage of lychees, ice cubes are placed in the fresh-keeping boxes to keep the lychees fresh. However, the ice cubes melt over time, and the melted water remains in the fresh-keeping boxes and cannot be cleaned in time, which accelerates the melting of the ice cubes. Moreover, under the influence of external temperature, the humidity inside the fresh-keeping box increases, which also accelerates the melting of the ice cubes and reduces the preservation effect of the lychees.

[0004] Therefore, a lychee freezing and fresh-keeping box with adjustable humidity is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a lychee frozen fresh-keeping box with adjustable humidity, comprising: a fresh-keeping box, a water leakage plate fixedly installed on the bottom of the inner cavity of the fresh-keeping box, a partition provided on the inner cavity of the fresh-keeping box, a humidity sensor fixedly embedded on one side of the inner cavity of the fresh-keeping box, an exhaust device provided on one side of the fresh-keeping box, a cover installed on the top of the fresh-keeping box, and a control panel fixedly installed on one side of the fresh-keeping box.

[0007] As a preferred embodiment, a mounting frame is fixedly installed around the inner cavity of the fresh-keeping box, a drain port is provided at the bottom of one side of the fresh-keeping box, and a soft plug is movably embedded in the drain port.

[0008] As a preferred embodiment, a cross mounting frame is fixedly installed in the middle of the surface of the water leakage plate, a connecting rod is fixedly installed on the top of the cross mounting frame, and a water leakage pipe is connected through the bottom of the water leakage plate.

[0009] As a preferred embodiment, the bottom of the partition is movably installed on the top of the mounting frame surface, the partition is movably sleeved on the surface of the connecting rod, and multiple partitions are installed through the top of the partition, and multiple leakage holes are opened on the surfaces of the partition and the multiple partitions.

[0010] As a preferred embodiment, the exhaust device includes an air barrier and an exhaust pipe, one side of the air barrier is fixedly installed on one side of the fresh-keeping box, one end of the exhaust pipe is installed through one side of the fresh-keeping box, the other end of the exhaust pipe passes through one side of the air barrier and is connected to a micro exhaust fan, one side of the micro exhaust fan is fixedly installed on one side inside the air barrier, a connecting pipe is installed through the other side of the air barrier, and one end of the connecting pipe is connected to a check valve.

[0011] As a preferred embodiment, a sealing gasket is fixedly installed on the bottom of the cover plate, a rotating knob is installed on the top of the cover plate through a bearing, a threaded sleeve is fixedly connected to the bottom of the rotating knob, and a lifting rod is installed on the top of the cover plate.

[0012] As a preferred embodiment, the sealing gasket is movably embedded in the inner side of the fresh-keeping box, and the threaded sleeve is threadedly sleeved on the surface of the connecting rod.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. The utility model is used for frozen storage and transportation of lychees. First, the partition is taken out, and ice cubes of a certain height are placed on the surface of the leaking plate. Then, the partition is placed on the surface of the installation frame. An appropriate amount of ice cubes are added to the inside of each compartment again. After lychees are placed on the surface of the partition, the cover is placed on the top of the fresh-keeping box, the threaded sleeve is aligned with the connecting rod, and the rotary knob is rotated to thread the threaded sleeve and the connecting rod. As the threaded sleeve rotates, the cover is driven to move downward, squeezing the sealing gasket to fit the top of the fresh-keeping box to form a seal. After the ice cubes inside the fresh-keeping box melt, the water will flow along the surface of the leaking plate to the leaking pipe, and then flow from the leaking pipe to the bottom of the inner cavity of the fresh-keeping box. The melted ice water can be released by pulling out the soft plug in the drain port to prevent the ice cubes from being soaked in water and melting faster.

[0015] 2. The utility model has a humidity sensor installed inside the fresh-keeping box to detect the humidity inside the fresh-keeping box. The parameters are set through the control panel. When the humidity sensor detects that the humidity inside the fresh-keeping box exceeds the set maximum value and transmits it to the control panel, the control panel will start the micro-exhaust fan. The micro-exhaust fan generates suction and will extract the moisture in the fresh-keeping box through the exhaust pipe and discharge it to the outside through the connecting pipe and the check valve. The micro-exhaust fan will automatically stop after a certain period of time, and the check valve will reset to block the outside air from entering the air isolation chamber. The humidity inside the fresh-keeping box is adjusted by the exhaust device to avoid excessive humidity inside the fresh-keeping box to accelerate the melting of ice cubes, thereby improving the frozen preservation function of litchi.
