[0027] The refrigeration box will be described in detail below through specific embodiments:

[0028] Referring to Figures 1 to 3 The utility model provides a refrigeration box which comprises a box body 1, an inner container 2 and a shelf 4.

[0029] The inner container 2 is arranged in the box body 1, and a refrigeration air duct 3 is formed between the outer wall of the inner container 2 and the inner wall of the box body 1, the refrigeration air duct 3 can reduce the temperature of the gas passing through the refrigeration air duct 3 to form low-temperature gas, the inner container 2 forms a refrigeration cavity 21, the refrigeration cavity 21 is communicated with the refrigeration air duct 3 to transport low-temperature gas to the refrigeration cavity 21 through the refrigeration air duct 3, thereby reducing the temperature in the refrigeration cavity 21. Specifically, a certain gap can be reserved between the outer wall of the inner container 2 and the inner wall of the box body 1 to form the refrigeration air duct 3.

[0030] In specific implementation, the shelf 4 is arranged in the refrigeration cavity 21 and supported on the bottom wall of the refrigeration cavity 21, the bottom of the shelf 4 is provided with an air passage 41, the air passage 41 is communicated with the refrigeration air duct 3 to transport low-temperature gas to the air passage 41 through the refrigeration air duct 3, the shelf 4 is formed with a containing cavity 42 for placing medicines, and the containing cavity 42 is located above the air passage 41.

[0031] That is, the refrigeration air duct 3 and the refrigeration cavity 21 of the inner container 2 are communicated, and low-temperature gas can be transported to the refrigeration cavity 21 through the refrigeration air duct 3 to reduce the temperature in the refrigeration cavity 21. When the medicine is placed in the containing cavity 42 on the shelf 4, the air passing channel 41 is located between the bottom of the medicine and the bottom wall of the refrigeration cavity 21. By communicating the air passing channel 41 with the refrigeration air duct 3, the low-temperature gas can pass through the bottom of the medicine. Compared with the mode that the medicine directly contacts the bottom wall of the refrigeration cavity 21, the circulation performance of the low-temperature gas in the refrigeration cavity 21 can be improved, so that the medicine can fully contact the low-temperature gas, and at the same time, the temperature at the bottom of the shelf 4 can be reduced, thereby the temperature difference between the refrigeration cavity 21 and the bottom of the shelf 4 can be reduced, the cooling speed can be improved, and the refrigeration effect of the medicine in the refrigeration box can be further improved.

[0032] In some embodiments, referring to Figure 1 As shown in the figure, the bottom wall of the inner container 2 is provided with ventilation holes 22, and the ventilation holes 22 are correspondingly arranged with the air passing channel 41 to communicate the air passing channel 41 and the refrigeration air duct 3, so that the low-temperature gas cooled by the refrigeration air duct 3 can directly enter the air passing channel 41 through the ventilation holes 22, thereby improving the circulation performance of the gas in the refrigeration cavity 21 and the cooling speed.

[0033] Continuing to refer to Figure 1 As shown in the figure, the number of the air passing channel 41 and the ventilation hole 22 is multiple, and they are one-to-one correspondingly arranged, which can increase the contact area between the bottom of the shelf 4 and the low-temperature gas, and further improve the cooling effect.

[0034] In specific implementation, the air passing channel 41 is arranged to extend along a first direction, and a plurality of air passing channels 41 are arranged in sequence and spaced apart along a second direction, wherein the first direction and the second direction are arranged at an angle. Specifically, the first direction can be the length direction of the refrigeration box, and the second direction can be the width direction of the refrigeration box. In this way, the low-temperature gas can uniformly contact the bottom of the shelf 4, and the temperature of the bottom of the shelf 4 can be uniformly reduced to ensure the cooling effect.

[0035] Of course, the first direction and the second direction can also be other directions, and the present application does not limit this, as long as they can be communicated with the refrigeration air duct 3 to uniformly reduce the temperature of the bottom of the shelf 4.

[0036] Referring to Figure 1 As shown in the figure, the inner container 2 includes a bottom wall and four side walls, and the bottom wall and the four side walls jointly enclose the refrigeration cavity 21. The bottom wall, the side walls and the shelf 4 can be formed as an integrated structure, or can be respectively formed as separate structures, or can be arbitrarily combined to form a plurality of integrated modules, such as the combination of the bottom wall and one of the side walls as an integrated module, or the combination of the shelf 4 and the bottom wall as an integrated module, or the combination of the shelf 4 and one of the side walls as an integrated module. The present application does not limit this, and the specific arrangement can be made according to the actual installation requirements.

[0037] In some embodiments, the side wall and / or the bottom wall of the accommodating cavity 42 is / are a ventilation structure, that is, the side wall of the accommodating cavity 42 is a ventilation structure, or the bottom wall of the accommodating cavity 42 is a ventilation structure, or both the side wall and the bottom wall of the accommodating cavity 42 are ventilation structures. In this way, the low-temperature gas cooled by the refrigeration air duct 3 can enter the accommodating cavity 42, so that the medicine can be more fully contacted with the low-temperature gas, and the refrigeration effect of the medicine can be ensured.

[0038] In particular, the shelf 4 is a grid structure, and the grids on the grid structure can respectively form the air passing channels 41 to enable the low-temperature gas to pass through the bottom of the medicine, and form the ventilation structure on the side wall or the bottom wall of the accommodating cavity 42 to enable the medicine to be more fully contacted with the low-temperature gas, so that the flow performance of the low-temperature gas in the refrigeration cavity 21 can be increased, and the cooling speed can be improved.

[0039] In other embodiments, a plurality of ventilation grooves are formed on the shelf 4, and the ventilation grooves are communicated with the accommodating cavity 42, so that the side wall or the bottom wall of the accommodating cavity 42 can be formed as a ventilation structure. Of course, the side wall or the bottom wall of the accommodating cavity 42 can also be ventilated by other means, which is not limited in the present application and can be specifically set according to actual needs.

[0040] In some embodiments, referring to FIG. 1, the refrigeration air duct 3 is arranged in the refrigeration cavity 21, and the refrigeration air duct 3 is communicated with the refrigeration cavity 21. Figure 1 Specifically, the evaporator 5 is a finned evaporator.

[0041] That is, when the gas passes through the evaporator 5, heat exchange can be generated between the gas and the evaporator 5, the heat in the gas can be removed by the evaporator 5, and the temperature of the gas itself can be reduced to generate low-temperature gas. In particular, the evaporator 5 is fixed on the inner wall of the box body 1 or the outer wall of the inner container 2.

[0042] In some embodiments, the refrigeration air duct 3 is provided with a cold storage box 7, the cold storage box 7 is arranged in close contact with the evaporator 5, the cold storage box 7 forms a cavity therein, and the cavity is filled with a cold storage medium. The cold storage medium can absorb and release cold energy to adapt to two working modes of the refrigeration box.

[0043] Specifically, when stable power supply can be achieved, refrigeration can be achieved by the evaporator 5, the cold storage box 7 is arranged in close contact with the evaporator 5, and the evaporator 5 can simultaneously cool the air to achieve cooling of the refrigeration cavity 21 and cool the cold storage medium to enable the cold storage box 7 to have a cold storage function; when power is temporarily cut off or long-distance transportation is performed, the evaporator 5 stops refrigeration, the cold storage box 7 can release cold energy to reduce the temperature of the gas passing through the refrigeration air duct 3 by the cold storage box 7, the temperature rising speed in the refrigeration cavity 21 after power cut-off can be reduced, and the cold energy can also be returned to the evaporator 5 to reduce the temperature of the evaporator 5.

[0044] In specific implementation, referring to Figure 2 and Figure 3 , a support frame 23 is arranged on the outer wall of the inner container 2, and the cold storage box 7 is fixed on the support frame 23. The support frame 23 can be assembled integrally with the inner container 2, and the operation is simple.

[0045] In some embodiments, the distance between the outer wall of the inner container 2 and the inner wall of the box 1 is greater than or equal to 20 mm and less than or equal to 25 mm.

[0046] It can be understood that the distance between the outer wall of the inner container 2 and the inner wall of the box 1 should not be too large, so that the refrigeration cavity 21 can have a large enough space for storing medicines under the condition of limited overall size, and the volume of the refrigeration cavity 21 is not too small, that is, the distance between the outer wall of the inner container 2 and the inner wall of the box 1 should be less than or equal to 25 mm.

[0047] Further, in order to ensure the cooling efficiency, the distance between the outer wall of the inner container 2 and the inner wall of the box 1 should not be too small, so that enough air can pass through the refrigeration air duct 3 to generate a sufficient amount of low-temperature air to achieve the cooling of the refrigeration cavity 21, that is, the distance between the outer wall of the inner container 2 and the inner wall of the box 1 should be greater than or equal to 20 mm.

[0048] In some embodiments, the refrigeration air duct 3 has an air inlet 31 and an air outlet 32, and the refrigeration cavity 21, the air inlet 31, the air outlet 32 and the refrigeration cavity 21 form a gas circulation loop, and the gas circulation loop is provided with a fan 6. In this way, under the action of the fan 6, the gas can enter the refrigeration air duct 3 through the air inlet 31 in the refrigeration cavity 21, and can also enter the refrigeration cavity 21 through the air outlet 32 in the refrigeration air duct 3, that is, the gas can circulate in the gas circulation loop and circulate, and in the circulation process, the gas can also be cooled by the refrigeration air duct 3 to gradually reduce the temperature of the refrigeration cavity 21.

[0049] In specific implementation, the fan 6 can be arranged at the air inlet 31 to drive the gas to circulate in the gas circulation loop. Of course, the fan 6 can also be arranged at other positions of the gas circulation loop, and the present application does not make any limitation thereon, as long as it can drive the gas to circulate in the gas circulation loop to gradually generate low-temperature gas and reduce the temperature of the refrigeration cavity 21.

[0050] Specifically, referring to Figure 1 and Figure 2 , an opening can be directly provided on the inner container 2 to form the air inlet 31 or the air outlet 32, or the air inlet 31 or the air outlet 32 can be formed at the gap between the inner container 2 and the box 1, and the present application does not make any limitation thereon, which can be specifically arranged according to actual needs.

[0051] In some embodiments, with reference to Figure 1 As shown in the drawings, the refrigeration box further comprises a door body 8, which is arranged on the top of the box body 1 and can open and close the box body 1 to realize the taking and placing of the medicines. The top of the shelf 4 is arranged separately from the door body 8. In this way, the low-temperature gas cooled by the refrigeration air duct 3 can pass between the top of the shelf 4 and the door body 8 to further increase the flow performance of the low-temperature gas in the refrigeration cavity 21, so that the temperature of different areas in the refrigeration cavity 21 can be more uniform.

[0052] In specific implementation, the box body 1 and / or the door body 8 are provided with a heat preservation foaming layer, that is, the heat preservation foaming layer can be arranged on the box body 1, or the heat preservation foaming layer can be arranged on the door body 8, or the heat preservation foaming layer can be arranged on both the box body 1 and the door body 8 to enhance the cold preservation performance of the refrigeration cavity 21 as a whole and improve the product performance.
