[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0029] The present invention will be further described below with reference to the embodiments.
[0030] In some embodiments, please refer to the appendix of the specification. Figure 1-6 A dual-temperature zone cold storage trolley cold chain logistics box includes a storage box 110, and a cooling mechanism 120 is provided on the surface of the storage box 110 for cooling the interior of the storage box 110:
[0031] The partition structure 200 includes a partition plate 210 fixedly connected to the inner wall of the storage box 110, one side of the partition plate 210 and the interior of the storage box 110 form a first temperature zone, and the other side of the partition plate 210 and the interior of the storage box 110 form a second temperature zone, a channel 250 is opened on the surface of the partition plate 210, two symmetrically distributed mounting bars 230 are fixedly connected to one side of the partition plate 210, and a door body 240 for blocking the channel 250 is slidably connected between the two mounting bars 230, and an auxiliary component 220 for guiding the cooling airflow in the first temperature zone into the second temperature zone is provided on the surface of the partition plate 210, and a sealing bag 2406 is embedded and installed on the side of the door body 240 close to the partition plate 210.
[0032] In an embodiment of the present invention, the cooling air flow is introduced into the first temperature zone through the cooling mechanism 120 for heat exchange and then introduced into the second temperature zone through the auxiliary component 220. After the door body 240 blocks the channel 250, the first temperature zone and the second temperature zone can only be connected through the auxiliary component 220.
[0033] In an embodiment of the present invention, the cooling air flow is introduced into the first temperature zone for heat exchange and then introduced into the second temperature zone through the auxiliary component 220, so that the temperature in the first temperature zone is lower than the temperature in the second temperature zone. By opening the door body 240, it is convenient to place the items to be stored in the first temperature zone. After closing, the connection between the first temperature zone and the second temperature zone is reduced, and the cooling gas is prevented from flowing through this area, thereby increasing the residence time of the cooling gas in the first temperature zone and enhancing the cooling effect in the first temperature zone.
[0034] In one example of the present invention, the space of the first temperature zone is smaller than that of the second temperature zone, so that the cold energy carried by the cooling gas is more concentrated, thereby forming a lower temperature storage condition inside the first temperature zone than inside the second temperature zone. The partition plate 210 and the door body 240 can cut off the channel 250 connecting the first temperature zone and the second temperature zone, reducing the dissipation of cold energy in the first temperature zone to the second temperature zone, thereby improving the refrigeration effect.
[0035] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, a connecting cavity 2401 is opened inside the door body 240, and an extrusion plate 2403 is slidably connected to the inside of the connecting cavity 2401. One side of the extrusion plate 2403 is fixedly connected to a uniformly distributed connecting rod 2405, and the other end of the connecting rod 2405 passes through the door body 240 and is fixedly connected to the pressure plate 2402.
[0036] A storage chamber is formed between the side of the extrusion plate 2403 away from the connecting rod 2405 and the interior of the connecting chamber 2401. The interior of the storage chamber is filled with inert gas. A uniformly distributed first spring 2404 is fixedly connected between the other side of the extrusion plate 2403 and the inner wall of the connecting chamber 2401.
[0037] The surface of the sealing bag 2406 is connected to a conduit 2407 , and the other end of the conduit 2407 is connected to the air storage chamber.
[0038] In an embodiment of the present invention, during the closing process of the door body 240, the inner wall of the storage box 110 is used to squeeze the pressure plate 2402 so that it can fit the surface of the door body 240. During this process, the pressure plate 2402 drives the connecting rod 2405 to shrink to the inside of the connecting cavity 2401, which can drive the extrusion plate 2403 to squeeze the inert gas stored in the storage cavity. The squeezed inert gas can be injected into the interior of the sealing bag 2406 through the conduit 2407, causing it to bulge and fit the surface of the partition plate 210.
[0039] In an embodiment of the present invention, the bulging sealing bag 2406 is used to strengthen the surface of the partition plate 210 and reduce the gap between the door body 240 and the partition plate 210 after closing. Compared with the traditional separation method, this method can reduce the dissipation of cold energy through the gap to the second temperature zone, thereby strengthening the isolation effect between the first temperature zone and the second temperature zone.
[0040] In some embodiments, as Figure 3 、 Figure 4 and Figure 6As shown, as a preferred embodiment of the present invention, the auxiliary component 220 includes a connecting plate 2201 embedded and installed on the surface of the partition plate 210, and the surface of the connecting plate 2201 is provided with evenly distributed mounting holes. The side of the connecting plate 2201 close to the first temperature zone is fixedly connected to a connecting shell 2204, and the surface of the connecting shell 2204 is provided with evenly distributed through holes 2205.
[0041] The inner wall of the mounting hole is fixedly connected with a mounting plate 2202, and the side of the mounting plate 2202 close to the connecting shell 2204 is fixedly connected with a mounting column 2207. The surface of the mounting column 2207 is slidably connected with a sealing plate 2208, and the outer side of the sealing plate 2208 is slidably connected to the inner wall of the mounting hole.
[0042] A second spring 2209 is fixedly connected to the surface of the sealing plate 2208 , and the other side of the second spring 2209 is fixedly connected to the surface of the mounting plate 2202 . A through groove 2210 is provided on the surface of the mounting column 2207 between the sealing plate 2208 and the mounting plate 2202 .
[0043] The inner wall of the connecting plate 2201 is rotatably connected to a rotating shaft 2203, one end of the rotating shaft 2203 passes through the connecting shell 2204 and is fixedly connected to a scraper 2206 in contact with the surface of the connecting shell 2204, and the other end of the rotating shaft 2203 passes through the connecting plate 2201 and is fixedly connected to a knob.
[0044] In the embodiment of the present invention, as the amount of cooling gas injected into the first temperature zone increases, the cooling gas can pass through the through hole 2205 and enter the interior of the mounting hole. Under the action of the gas pressure, the sealing plate 2208 is pushed to slide along the inner wall of the mounting post 2207 and compress the second spring 2209. When the sealing plate 2208 moves to the middle of the through groove 2210, the gas can pass through the through groove 2210 and bypass the sealing plate 2208 into the interior of the second temperature zone.
[0045] The rotating shaft 2203 can be driven to rotate by rotating the knob, and during this process, the scraper 2206 can be driven to rotate along the surface of the connecting shell 2204.
[0046] In the embodiment of the present invention, the setting of the auxiliary component 220 can prevent the gas from flowing from the second temperature zone to the first temperature zone, and prevent the temperature in the second temperature zone from interfering with the temperature in the first temperature zone, thereby improving the refrigeration effect in the first temperature zone and strengthening the isolation effect. At the same time, the scraper 2206 can be rotated to clean the surface of the connecting shell 2204, reducing blockage caused by ice.
[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
