[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Example 1

[0034] refer to Figure 1 As shown, an embodiment of the present application provides a reagent refrigeration device 100 , which includes a storage module 110 , a refrigeration module 120 and a power module 130 .

[0035] Specifically, combined Figures 1 to 3As shown, the storage module 110 includes a heat preservation component 111, a refrigeration bin 112 and a positioning member 113, the heat preservation component 111 is connected to the refrigeration bin 112 and defines a storage space 114, the bottom surface of the refrigeration bin 112 is an inclined refrigeration surface 1121, the positioning member 113 is arranged in the storage space 114 and abuts against the refrigeration surface 1121, the positioning member 113 is provided with a plurality of positioning holes 1131, the center lines of the positioning holes 1131 are perpendicular to the refrigeration surface 1121, and the positioning holes 1131 are used to place the reagent bottle 200; the refrigeration module 120 is connected to the heat preservation component 111, and the refrigeration module 120 abuts against the side of the refrigeration surface 1121 away from the positioning member 113 ; The power module 130 is connected to the refrigeration module 120, and the storage module 110 is set to refrigerate the reagent bottle 200. The power module 130 supplies power to the refrigeration module 120. The bottom surface of the refrigeration bin 112 is an inclined refrigeration surface 1121. The refrigeration module 120 cools the reagent bottle 200 through the refrigeration surface 1121. The condensed water generated by the reagent refrigeration device 100 is collected by the inclined refrigeration bin 112 for unified processing. The positioning hole 1131 of the positioning member 113 is used to fix the reagent bottle 200. The insulation component 111 and the positioning member 113 can keep the temperature of the reagent bottle 200 constant and make the reagent bottle 200 in an inclined setting, so as to facilitate the liquid collection device to completely absorb the liquid in the reagent bottle 200. It should be noted that Figure 3 As shown, during the use of the reagent refrigeration device 100, the side of the accommodating space 114 away from the refrigeration module 120 is maintained in a horizontal position. At this time, the refrigeration surface 1121 is in an inclined state to facilitate the collection of the generated condensed water; when the center line of the positioning hole 1131 and the refrigeration surface 1121 are perpendicular to each other, that is, the reagent bottle 200 and the refrigeration surface 1121 remain in a vertical state, it is beneficial for the refrigeration surface 1121 to cool and refrigerate the reagent bottle 200, and at the same time, the reagent bottle 200 is in an inclined setting, and the liquid collection device absorbs the liquid in the reagent bottle 200 to reduce the reagent residue at the bottom of the reagent bottle 200.

[0036] In addition, refer to Figure 5 As shown, the power module 130 can use an external circuit to power the refrigeration module 120. The power module 130 can also use an energy storage battery pack to power the refrigeration module 120. The energy storage battery pack can be charged and used. The type of the energy storage battery pack is not specifically limited, such as lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, sodium batteries or solid-state batteries, etc., which have good portability and enable the power module 130 to provide a long period of continuous power supply capability, which is used to continuously cool the refrigeration module 120 and keep the reagent bottle 200 in a refrigerated state for a long time, thereby achieving a better refrigeration effect.

[0037] Optionally, refer to Figure 2 As shown, the insulation component 111 includes a first insulation component 1111, and the first insulation component 1111 is provided with a first opening 1111a. The refrigeration module 120 is passed through the opening and abuts against the refrigeration surface 1121. The first insulation component 1111 can enable the refrigeration module 120 to cool down the refrigeration surface 1121 through the first opening 1111a, thereby keeping the temperature of the reagent bottle 200 constant and achieving a refrigeration effect on the reagent bottle 200.

[0038] Optionally, combined Figure 1 and Figure 2 As shown, the insulation component 111 also includes a second insulation component, which is connected to the side of the first insulation component 1111 facing away from the refrigeration module 120, so that the second insulation component can limit the positioning component 113, and the second insulation component can be connected to or separated from the first insulation component 1111 to facilitate the installation and removal of the positioning component 113. The second insulation component is used to limit and position the positioning component 113 to prevent the positioning component 113 from escaping from the first opening 1111a, which affects the transportation and storage of the reagent bottle 200.

[0039] In this embodiment, the positioning member 113 can be separated from the accommodating space 114 to facilitate the disassembly of the positioning member 113. On the one hand, the positioning member 113 can be replaced, and on the other hand, it is easy to clean the positioning member 113, thereby reducing the situation where condensed water adheres to the positioning member 113, which has a better technical effect.

[0040] Alternatively, if Figure 1 As shown, the positioning member 113 is a positioning block, the accommodating space 114 is provided with a second opening 1141, and the positioning block can close the second opening 1141. The reagent bottle 200 on the positioning block is exposed to the outside through the second opening 1141, which is convenient for personnel to take.

[0041] It can be understood that the positioning block is detachably connected to the refrigeration bin 112 to facilitate replacement and cleaning of the positioning block. Exemplarily, the positioning block can be made of hollow insulation material. Accordingly, the positioning block can be made of hollow insulation material using a 3D printing process. The 3D printing process can be manufactured according to a preset shape structure, and is easy to shape for customized processing. The hollow insulation material has a lower air thermal conductivity and better insulation effect. The 3D printing material with a hollow structure can reduce the amount of raw materials used to reduce manufacturing costs. At this time, the positioning block has a hollow structure, which reduces heat exchange with the external space. At the same time, it has better thermal insulation performance and lighter weight, which improves the scope of application and meets the needs of various usage scenarios.

[0042] In summary, the reagent refrigeration device 100 is provided with a storage module 110 to refrigerate the reagent bottle 200, the power module 130 supplies power to the refrigeration module 120, the bottom surface of the refrigeration bin 112 is an inclined refrigeration surface 1121, the refrigeration module 120 cools the reagent bottle 200 through the refrigeration surface 1121, and the condensed water generated by the reagent refrigeration device 100 is collected by the inclined refrigeration bin 112 for unified processing, the positioning hole 1131 of the positioning member 113 is used to fix the reagent bottle 200, the positioning member 113 is detachable for replacement and cleaning of the positioning member 113, the insulation component 111 and the positioning member 113 can keep the temperature of the reagent bottle 200 constant and make the reagent bottle 200 in an inclined setting, so as to facilitate the liquid collection device to completely absorb the liquid in the reagent bottle 200 and reduce the residual liquid in the reagent bottle 200.

[0043] Example 2

[0044] refer to Figure 1 As shown, an embodiment of the present application provides another reagent cold storage device 100 , which includes a storage module 110 , a refrigeration module 120 and a power module 130 .

[0045] Specifically, combined Figures 1 to 3 As shown, the storage module 110 includes an insulation component 111, a refrigeration bin 112 and a positioning member 113. The insulation component 111 is connected to the refrigeration bin 112 and defines a storage space 114. The bottom surface of the refrigeration bin 112 is an inclined refrigeration surface 1121. The positioning member 113 is arranged in the storage space 114 and abuts against the refrigeration surface 1121. The positioning member 113 is provided with a plurality of positioning holes 1131. The center lines of the positioning holes 1131 are perpendicular to the refrigeration surface 1121. The positioning holes 1131 are used to place reagent bottles 200. The condensed water generated by the reagent refrigeration device 100 is collected by the inclined refrigeration bin 112 for unified processing. The positioning holes 1131 of the positioning member 113 are used to fix the reagent bottles 200.

[0046] Specifically, the refrigeration module 120 is connected to the insulation component 111, and the refrigeration module 120 abuts against the side of the refrigeration surface 1121 away from the positioning member 113; the power module 130 is connected to the refrigeration module 120, the storage module 110 is set to refrigerate the reagent bottle 200, and the power module 130 supplies power to the refrigeration module 120. The bottom surface of the refrigeration bin 112 is an inclined refrigeration surface 1121. The refrigeration module 120 cools the reagent bottle 200 through the refrigeration surface 1121. The insulation component 111 and the positioning member 113 can keep the temperature of the reagent bottle 200 constant and make the reagent bottle 200 in an inclined setting, so as to facilitate the liquid collection device to completely absorb the liquid in the reagent bottle 200.

[0047] It should be noted that if Figure 1 and Figure 2 As shown, during the use of the reagent refrigerator 100, the side of the accommodating space 114 away from the refrigeration module 120 is kept in a horizontal position. At this time, the refrigeration surface 1121 is in an inclined state to facilitate the collection of the generated condensed water.

[0048] In this embodiment, when the center line of the positioning hole 1131 and the refrigeration surface 1121 are perpendicular to each other, that is, the reagent bottle 200 and the refrigeration surface 1121 remain in a vertical state, the refrigeration surface 1121 is conducive to cooling and refrigerating the reagent bottle 200, and at the same time, the reagent bottle 200 is in an inclined setting, and the liquid collection device absorbs the liquid in the reagent bottle 200 to reduce the reagent residue at the bottom of the reagent bottle 200.

[0049] In this embodiment, reference Figure 1 As shown, the positioning hole 1131 has one or more shapes and sizes to accommodate reagent bottles 200 of different sizes. The positioning hole 1131 fixes and positions the reagent bottle 200 and can reduce the contact area between the reagent bottle 200 and the external air to ensure the refrigeration effect of the reagent bottle 200. Optionally, the positioning hole 1131 can also be set as a through hole, which can enable the reagent bottle 200 to contact the refrigeration surface 1121, thereby improving the refrigeration and insulation effect of the reagent bottle 200.

[0050] Optionally, refer to Figure 2 and Figure 3As shown, the insulation component 111 includes a first insulation component 1111, and the first insulation component 1111 is provided with a first opening 1111a. The refrigeration module 120 is inserted through the opening and abuts against the refrigeration surface 1121. The first insulation component 1111 can set the refrigeration surface 1121 of the refrigeration warehouse 112 through the first opening 1111a. The first insulation component 1111 insulates the refrigeration warehouse 112 and will not affect the refrigeration effect of the refrigeration module 120, so that the refrigeration module 120 cools down the refrigeration surface 1121, keeps the temperature of the reagent bottle 200 constant, and achieves a refrigeration effect on the reagent bottle 200.

[0051] Optionally, combined Figure 1 and Figure 2 As shown, the insulation component 111 also includes a second insulation component, which is connected to the side of the first insulation component 1111 away from the refrigeration module 120, so that the second insulation component can limit the positioning component 113, and the second insulation component can be connected or separated from the first insulation component 1111, so as to facilitate the installation and removal of the positioning component 113. The second insulation component is used to limit and position the positioning component 113 to avoid the positioning component 113 from falling out of the first opening 1111a, affecting the transportation and storage of the reagent bottle 200. Exemplarily, the second insulation component and the first insulation component 1111 can be connected by a clamping structure or by screw fixing.

[0052] Optionally, refer to Figure 2 and Figure 3 As shown, the refrigeration bin 112 of the dustpan structure is in contact with the positioning member 113 and the first heat-insulating member 1111, and the refrigeration bin 112 can be separated from the first heat-insulating member 1111. For example, the first heat-insulating member 1111 is a dustpan-shaped structure, so that the refrigeration bin 112 can be installed on the first heat-insulating member 1111. The first heat-insulating member 1111 and the positioning member 113 fix and limit the refrigeration bin 112. The refrigeration bin 112 and the first heat-insulating member 1111 can be separated and removed, so that the condensed water in the inclined refrigeration bin 112 can be collected for easy cleaning. For example, the first heat-insulating member 1111 is provided with a groove of a dustpan-shaped structure. When the refrigeration bin 112 is installed in the groove, the groove has an inclined surface, so that the opposite ends of the refrigeration bin 112 have different heights, and the opposite ends of the refrigeration bin 112 form an inclined surface, and the condensed water droplets flow to the lower part of the refrigeration bin 112 for collection.

[0053] It is worth noting that the combination Figure 1As shown, one end of the accommodating space 114 has an opening, which is convenient for placing the positioning member 113 in the accommodating space 114 and forming an open structure for the reagent refrigeration device 100 on which the reagent bottle 200 is placed, so that the reagent bottle 200 on the positioning member 113 can be taken more conveniently. Therefore, the reagent refrigeration device 100 is in an open environment, so that the reagent bottle 200 is exposed to the outside, and the refrigeration temperature of the reagent bottle 200 is kept constant, and the reagent refrigeration device 100 has a better refrigeration effect on the reagent bottle 200.

[0054] Optionally, the positioning member 113 is a positioning block, and the accommodating space 114 is provided with a second opening 1141. The positioning block can close the second opening 1141, and the reagent bottle 200 on the positioning block is exposed to the outside through the second opening 1141, so as to facilitate personnel to take it. Demonstratively, the second opening 1141 and the first opening 1111a are arranged relative to each other, and the second opening 1141 and the first opening 1111a are not parallel.

[0055] In one embodiment, specifically, referring to Figure 4 As shown, the refrigeration module 120 includes a cooling member 121 and a cooling sheet 122, one side of the cooling sheet 122 is connected to the cooling member 121, and the side of the cooling member 121 facing away from the cooling sheet 122 is connected to the cooling surface 1121, and the cooling sheet 122 cools the cooling surface 1121 of the refrigeration bin 112 through the cooling member 121, so as to achieve the effect of cooling and refrigerating the reagent bottle 200. Exemplarily, a heat-insulating material is filled between the refrigeration module 120 and the storage module 110, and the heat-insulating material can be a foaming glue.

[0056] It can be understood that the cooling plate 122 is a semiconductor cooling plate 122, which is a heat pump. When direct current passes through a thermocouple formed by two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the thermocouple respectively. That is, when one side of the cooling plate 122 is used for cooling, the other side of the cooling plate 122 will generate heat. The other side of the cooling plate 122 can be cooled and dissipated to improve the product performance of the cooling plate 122.

[0057] Alternatively, if Figure 1 and Figure 4 As shown, the refrigeration module 120 further includes a heat dissipation component 123 , which is connected to a side of the refrigeration fin 122 away from the cooling member 121 , and is used to dissipate heat and cool the other side of the refrigeration fin 122 .

[0058] Furthermore, the heat dissipation assembly 123 includes a radiator 1231 and a heat dissipation fan 1232. The heat dissipation fan 1232 is connected to the cooling fin 122 through the radiator 1231. The radiator 1231 dissipates heat and cools the heating surface of the cooling fin 122. The heat dissipation fan 1232 accelerates the air flow rate around the radiator 1231 to achieve the effect of heat dissipation and cooling. The radiator 1231 can be a copper tube radiator 1231, which has a better heat dissipation effect.

[0059] Optionally, refer to Figure 1 As shown, the refrigeration module 120 also includes a temperature sensor 124, which is connected to the refrigeration bin 112 and is disposed between the positioning member 113 and the refrigeration bin 112. The temperature sensor 124 is used to monitor the refrigeration temperature during refrigeration, and manage and control the refrigeration temperature of the reagent refrigeration device 100 through the refrigeration plate 122, and adjusts the refrigeration temperature according to the refrigeration temperature requirements of different reagents to keep the reagent refrigeration temperature in a constant temperature state.

[0062] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
