[0027] An embodiment of the present invention is shown in conjunction with the accompanying drawings.
[0028] Example 1:
[0029] Please see Figures 1-3 This is the first embodiment of the present utility model.
[0030] This embodiment provides a fruit preservation device, including a transport box assembly 1, a protective assembly 4 detachably connected to the transport box assembly 1, and a cooling assembly 3 for cooling the transport box assembly 1.
[0031] The shipping container assembly 1 includes: a foam box body 101;
[0032] The cooling component 3 includes: two dry ice storage slots 301 fixed inside the foam box body 101; a dry ice vent 303 opened on the side of the dry ice storage slot 301 near the vertical center line of the foam box body 101; a bottom connecting rod 304 fixed to the bottom of the foam box body 101; side connecting rods 302 fixed on the left and right sides of the bottom connecting rod 304; and a side air supply hole 305 opened on the side of the side connecting rod 302.
[0033] Specifically, the top of the dry ice storage tank 301 is provided with a removable cover plate. The dry ice storage tank 301 is connected to the side connecting rod 302 through the bottom connecting rod 304, and the side connecting rod 302 is connected to the foam box body 101 through the side air supply hole 305.
[0034] Furthermore, the dry ice placed in the dry ice storage tank 301, after sublimation, can be discharged into the center of the foam box 101 through the dry ice vent 303, and at the same time, it can also be transported into the foam box 101 through the side air supply hole 305 via the bottom connecting rod 304 and the side connecting rod 302.
[0035] Specifically, the transport box assembly 1 also includes: a central support column 102 fixed at the center of the foam box body 101; and four corner support columns 103 fixed at the four corners inside the foam box body 101.
[0036] Furthermore, the central support column 102 is used to support the protective component 4, and the height of the central support column 102 is greater than the height of the dry ice storage tank 301.
[0037] Specifically, the top of the foam box 101 is detachably connected to a box cover 2, and there is a gap between the box cover 2 and the foam box 101, so it is not completely sealed.
[0038] Furthermore, the carbon dioxide gas produced by the sublimation of dry ice can be discharged through the gap between the box lid 2 and the foam box body 101, thus preventing the foam box body 101 from being in a high carbon dioxide content environment.
[0039] In this embodiment, after dry ice is stored in the dry ice storage tank 301 by the cooling component 3, the dry ice storage tank 301 is sealed by the cover plate. The carbon dioxide gas generated by the dry ice is discharged into the center of the foam box 101 through the dry ice vent 303. At the same time, a part of the carbon dioxide can be transported to the inside of the foam box 101 through the side air inlet 305 through the bottom connecting rod 304 and the side connecting rod 302. The carbon dioxide gas can reach the center and the side, avoiding the center temperature being too high and affecting the low temperature preservation effect on the fruit.
[0040] Example 2:
[0041] Please see Figures 3-5 This is the second embodiment of the present utility model.
[0042] Specifically, the protective component 4 includes: a first layer plate 401 disposed inside the lower part of the foam box body 101; a second layer plate 404 disposed above the first layer plate 401; and a flow hole 402 formed inside the first layer plate 401 and the second layer plate 404.
[0043] Furthermore, the first plate 401 and the second plate 404 are used to place fruit, and the carbon dioxide at the bottom can circulate through the flow hole 402, thereby achieving cooling in the center.
[0044] Specifically, the protection component 4 also includes: connecting rods 406 fixed to the four bottom corners of the first layer plate 401; and limiting rods 408 fixed to the four top corners of the first layer plate 401.
[0045] Furthermore, the connecting rods 406 on the first layer plate 401 can be inserted into the four corner support columns 103 to install the first layer plate 401.
[0046] Specifically, the protective component 4 also includes: shelf support rods 407 fixed to the four bottom corners of the second shelf 404; fruit placement compartments 403 fixed to the top of the first shelf 401 and the second shelf 404; and a central support member 405 disposed between the fruit placement compartments 403.
[0047] Furthermore, the fruit compartment 403 has a hexagonal structure. When fruit is placed between the fruit compartments 403, it can deform to a certain extent according to the shape of the fruit. Foam cotton or similar materials can be filled between the outer side of the fruit compartment 403 and the central support 405 to provide a certain degree of protection. The fruit compartment 403 can be made of polyethylene foam, bubble wrap, etc.
[0048] Specifically, the connecting rod 406 penetrates the interior of the four corner support columns 103, and the limiting rod 408 penetrates the bottom of the shelf support rod 407.
[0049] Furthermore, the second layer plate 404 is supported by the layer plate support rod 407 inserted outside the limiting rod 408.
[0050] In this embodiment, by setting a first layer plate 401 and a second layer plate 404, two layers of fruit can be placed. Fruit placement grids 403 are set above both the first layer plate 401 and the second layer plate 404. The fruit placement grids 403 have a hexagonal structure. When fruit is placed between the fruit placement grids 403, it can deform to a certain extent according to the shape of the fruit. Foam cotton or similar materials can be filled between the outer side of the fruit placement grids 403 and the middle support member 405 to play a certain protective role.
[0051] Working principle: Based on the required temperature of the fruit, it can be placed in a suitable position inside the foam box 101. The temperature of the first shelf 401 is lower than that of the second shelf 404. The side connecting rod 302 is adapted to the height of the first shelf 401 and the second shelf 404. Dry ice is placed inside the dry ice storage tank 301 and sealed with a cover. The carbon dioxide gas generated by the dry ice is discharged from the dry ice vent 303 into the center of the foam box 101 and can rise to the first shelf 401 and the second shelf 404 through the flow hole 402. Meanwhile, a portion of carbon dioxide can be transported to the interior of the foam box 101 through the side air inlet 305 via the bottom connecting rod 304 and the side connecting rod 302. The carbon dioxide gas can reach the center and side positions, avoiding the center temperature being too high and affecting the low-temperature preservation effect on the fruit. The fruit is placed between the fruit placement compartments 403, and can deform to a certain extent according to the shape of the fruit. Foam cotton can be filled between the outer side of the fruit placement compartments 403 and the middle support member 405. The middle support member 405 has an X-shaped structure and can deform.
[0052] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
