In order to store some foods for a longer time and transport them farther, and also require freshness and safety, a quick-freezing storage is needed to perform quick-freezing treatment on the foods.

[0003] After retrieval, a Chinese patent with the publication number CN209512352U discloses an intelligent molecular quick-freezing storage, which includes a molecular quick-freezing storage body with a heat-insulating layer, a refrigeration source placed outside the molecular quick-freezing storage body, a detection unit, an artificial intelligence control system, and an environmental parameter regulation component; the environmental parameter regulation component includes a spray-type evaporator and a quick-freezing storage circulation fan group; a quick-freezing door is opened on the molecular quick-freezing storage body, and the side of the inner wall of the molecular quick-freezing storage body except the side where the quick-freezing door is opened is installed with a spray-type evaporator; a quick-freezing storage circulation fan group is installed on the top surface of the molecular quick-freezing storage body, and the refrigeration source is connected to the spray-type evaporator through a pipeline; a detection unit is installed inside the molecular quick-freezing storage body; the intelligent control system is connected to the above-mentioned detection unit, environmental parameter regulation component, and refrigeration source; the components connected thereto are controlled by the intelligent control system to cool the quick-freezing storage to achieve the purpose of quick-freezing.

[0004] In the above-mentioned prior art solution, the items to be frozen are placed on the material rack, then the material rack is placed in the quick-freezing storage, and then the liquid nitrogen in the liquid nitrogen tank is sent into the liquid nitrogen evaporator, so that the liquid nitrogen is sprayed into the quick-freezing storage to cool the items. However, in the actual use process, since the space of the quick-freezing storage is fixed, and the number of items frozen each time is often not fixed. When there are fewer items to be frozen, when more liquid nitrogen is sent into the quick-freezing storage, the liquid nitrogen cannot be fully utilized, which is easy to cause waste of liquid nitrogen; when there are more items to be frozen, the liquid nitrogen sent into the quick-freezing storage is relatively less, and the quick-freezing of the items inside the quick-freezing storage becomes slower, affecting the quick-freezing efficiency.

[0009] In some embodiments, a support component is arranged inside the box body, and the support component includes; A positioning groove and a support bar, the positioning grooves are equidistantly opened on the top wall surface of the support plate, and the support bar is slidably installed inside a plurality of positioning grooves; A strong magnetic plate, which is fixedly installed on the inner bottom wall surface of the box body, and the side wall surfaces of the strong magnetic plate and the support bar close to each other have the same magnetic poles.

[0010] In some embodiments, the support assembly further includes; A limit seat, which is fixedly installed on the bottom wall surface of the support bar.

[0011] In some embodiments, a plurality of ventilation holes are formed on the side wall of the support bar.

[0012] In some embodiments, a closing assembly is provided on the top of the box body, and the closing assembly includes; Fixed legs, there are four fixed legs in total, and the four fixed legs are divided into two groups and are fixedly installed at the left and right ends of the top wall surface of the box body in a mirror image manner. A rotating shaft is rotatably installed between two adjacent fixed legs, and limiting grooves are formed on the front and rear side wall surfaces inside the top sandwich of the box body; Sealing cloths, there are two sealing cloths in total, and the two sealing cloths are respectively fixedly installed at the left and right ends of the top wall surface of the diffusion plate. One ends of the two sealing cloths far away from the diffusion plate bypass the side wall of the rotating shaft and extend downward into the inside of the top sandwich of the box body, and the front and rear ends of the sealing cloths are respectively located inside the adjacent limiting grooves.

[0013] In some embodiments, the closing assembly further includes; Positioning blocks, ejector rods and connecting ropes. There are a plurality of positioning blocks in total, and the plurality of positioning blocks are respectively fixedly installed on the front, rear, left and right side wall surfaces of the two sealing cloths. The ejector rod is arranged on the top of the box body, the bottom end of the ejector rod slidably penetrates through the top wall surface of the box body and is fixedly installed on the top wall surface of the support plate, and two ends of the connecting rope are respectively fixedly connected to the side walls of two adjacent positioning blocks, and a groove for accommodating the connecting rope is formed on the side wall of the ejector rod.

[0014] A quick-freezing method for an intelligent molecular quick-freezing storage, including the following steps: The first step: Open the box door, place the items to be quick-frozen on the top end of the support bar, control the driving motor to work according to the height of the items, so that the output end of the driving motor rotates. Under the transmission of the driven gear, the transmission chain and the driving gear, the adjusting screw rotates, so that the support plate moves up or down, and adjusts the space on the top of the support plate where items can be placed; The second step: When the support plate moves downward, the sealing cloth is pulled out from the inside of the box body as the diffusion plate moves downward, increasing the gap between the two sealing cloths. Since the distance between the support plate and the strong magnetic plate is shortened, the repulsive force received by the support bar becomes stronger, and the support bar moves upward accordingly; Step 3: When the support plate moves upward, the distance between the support plate and the top inside the box body shortens, the repulsive force on the support bar weakens, the distance between the item on the top of the support bar and the top wall surface of the support plate decreases, the ejector rod moves upward together with the support plate, and thus the ejector rod pushes the connecting rope, causing the two ends of the connecting rope to approach the ejector rod. Therefore, the two ends of the connecting rope pull the two sealing cloths to move towards the same side, shortening the gap between the two sealing cloths; Step 4: Close the box door, then open the external liquid nitrogen tank. The liquid nitrogen enters the liquid nitrogen evaporator. The liquid nitrogen evaporator makes the liquid nitrogen into a mist state and sends it into the interior of the connecting pipe. The liquid nitrogen is sent into the interior of the diffusion plate and is respectively sent into the upper spray tank, the lower spray tank and the interior of the box body through multiple spray holes on the diffusion plate, so that the liquid nitrogen sprays out from the upper, lower, left, right and rear sides of the item, and quickly freezes the item placed on the top of the support bar.

[0015] Compared with the prior art, the remarkable advantages of the present invention are: First: In the present invention, the output end of the external liquid nitrogen tank is connected to the input end of the liquid nitrogen evaporator, and then the output end of the liquid nitrogen evaporator is connected to the tops of multiple connecting pipes. The liquid nitrogen is sent into the interior of the diffusion plate and is respectively sent into the upper spray tank, the lower spray tank and the interior of the box body through multiple spray holes on the diffusion plate, so as to quickly freeze the item placed on the top of the support plate; by controlling the operation of the driving motor, the output end of the driving motor works. Through the transmission of the driven gear, the transmission chain and the driving gear, multiple adjusting screws rotate in the same direction, so that the connecting slide plate moves up and down inside the sliding groove, thereby adjusting the height of the support plate. The part of the diffusion plate inside the box body is adjusted synchronously with the height of the support plate. When there are fewer items placed inside the box body, by moving the support plate upward, the space of the diffusion plate inside the box body is reduced, so that the liquid nitrogen sprayed out by the diffusion plate can be more concentrated around the item, improving the freezing speed of the item and reducing the loss of liquid nitrogen at the same time; this solves the problem of low utilization rate of liquid nitrogen in the existing quick-freezing storage.

[0016] Second: In the present invention, the position of the connecting pipe is fixed by the fixing strip and the fixing frame, and then the interior of the diffusion plate is divided into two parts by the partition plate. At the same time, since the partition plate is attached to the inner side wall of the diffusion plate, it will not interfere with the sliding of the diffusion plate. Since the bottom end of the connecting pipe is inside the box body, the liquid nitrogen output from the bottom end of the connecting pipe can only be inside the box body, avoiding the situation where the liquid nitrogen sprays out at the top of the box body.

[0017] Thirdly: In the present invention, by providing support bars on the top of the support plate, the items placed on the top of the support plate are supported by the support bars, increasing the gap between the items and the top wall surface of the support plate, facilitating the contact between liquid nitrogen and the bottom wall surface of the items. The liquid nitrogen on the top of the support plate can flow through the ventilation holes, enabling the liquid nitrogen to be more evenly distributed at the bottom of the items. When the support bars move downward together with the support plate, due to the repulsion between like magnetic poles, the shorter the distance between the support bars and the strong magnetic plate, the stronger the repulsive force received by the support bars, so they will move upward, increasing the space for the liquid nitrogen to flow at the bottom of the items. The space for the liquid nitrogen to flow on the top of the support plate can be adjusted at any time according to the items placed on the top of the support plate.

[0018] Fourthly: In the present invention, the top end of the upper spray groove is covered by a sealing cloth to limit the range of the downward distribution of liquid nitrogen. The diffusion plate will move downward synchronously with the support plate, pulling out the two sealing cloths from the inside of the box body. The gap between the adjacent ends of the two sealing cloths expands. The two sealing cloths are connected by a connecting rope. When the support plate moves upward, the ejector rod moves synchronously with the support plate, so the ejector rod can push the connecting rope upward. The two ends of the connecting rope pull the two sealing cloths to move into the inside of the box body, enabling the sealing cloth to re-seal the top end of the upper spray groove, facilitating the adjustment of the range of liquid nitrogen output at the top of the device according to the quantity of the items.

[0022] The present invention provides an intelligent molecular quick-freezing storage and a quick-freezing method by improvement. The technical solution of the present invention is as follows: Embodiment 1 As Figures 1-8As shown in the figure, an intelligent molecular quick-freezing storage includes a box body 1. A plurality of support legs 2 are fixedly installed on the bottom wall surface of the box body 1. Two box doors 7 are rotatably installed on the front side wall surface of the box body 1. The two box doors 7 facilitate the sealing of the interior of the box body 1. A liquid nitrogen tank and a liquid nitrogen evaporator are arranged outside the box body 1. A diffusion assembly extending outside the box body 1 is arranged inside the box body 1. The diffusion assembly includes a support plate 31, a diffusion plate 32, a connecting pipe 33, a fixing strip 341, a fixing frame 342, a partition plate 343, an upper spray groove 35 and a lower spray groove 36. The support plate 31 is slidably installed inside the box body 1. The diffusion plate 32 is in a "U" shape. The diffusion plate 32 slides through the top wall surface of the box body 1. The bottom end of the diffusion plate 32 is fixedly installed on the outer side wall of the support plate 31. A plurality of spray holes are opened on the side wall of the diffusion plate 32. The plurality of spray holes on the diffusion plate 32 are distributed such that the aperture is larger the closer it is to the bottom. There are a plurality of connecting pipes 33. The plurality of connecting pipes 33 slide through the top wall surface of the diffusion plate 32. The bottom end of the connecting pipe 33 is inside the box body 1. The top side plates of the box body 1 and the support plate 31 are both hollow. There are a plurality of upper spray grooves 35 and a plurality of lower spray grooves 36. The plurality of upper spray grooves 35 and the plurality of lower spray grooves 36 are respectively opened on the inner top wall surface of the box body 1 and the top wall surface of the support plate 31. The upper spray groove 35 and the lower spray groove 36 are respectively communicated with the top interlayer of the box body 1 and the hollow part inside the support plate 31. An upper communication groove 37 corresponding to the diffusion plate 32 is opened on the rear side wall surface inside the upper spray groove 35. The upper communication groove 37 is communicated with the top interlayer of the box body 1. Lower communication grooves 38 corresponding to the diffusion plate 32 are opened on the left and right side wall surfaces of the support plate 31. Connect the output end of the external liquid nitrogen tank to the input end of the liquid nitrogen evaporator, and then connect the output end of the liquid nitrogen evaporator to the top ends of the plurality of connecting pipes 33. Send the liquid nitrogen into the inside of the diffusion plate 32, and send it into the upper spray groove 35, the lower spray groove 36 and the inside of the box body 1 respectively through the plurality of spray holes on the diffusion plate 32 to quickly freeze the items placed on the top of the support plate 31. The fixing strip 341 is fixedly installed on the top wall surface of the box body 1. The fixing frame 342 is fixedly installed on the outer side wall top ends of the plurality of connecting pipes 33, and the fixing frame 342 is fixedly installed on the side wall of the fixing strip 341. The partition plate 343 is fixedly installed on the side wall of the connecting pipe 33. The position of the partition plate 343 is aligned with the top wall surface of the box body 1, and the partition plate 343 is attached to the inner side wall of the diffusion plate 32. Fix the position of the connecting pipe 33 through the fixing strip 341 and the fixing frame 342, and then divide the inside of the diffusion plate 32 into two parts through the partition plate 343. At the same time, since the partition plate 343 is attached to the inner side wall of the diffusion plate 32, it will not prevent the sliding of the diffusion plate 32. Since the bottom end of the connecting pipe 33 is inside the box body 1, the liquid nitrogen output from the bottom end of the connecting pipe 33 can only be inside the box body 1, avoiding the situation where the liquid nitrogen sprays out at the top of the box body 1.The outside of the box body 1 is provided with an adjustment component extending to the inside of the box body 1, and the adjustment component includes a driving motor 61, an adjusting screw 62, a transmission chain 64, a sliding groove 65 and a connecting slide plate 66. The driving motor 61 is fixedly installed at the bottom end of the side wall of the box body 1. There are a plurality of sliding grooves 65, and the plurality of sliding grooves 65 are respectively opened on the inner wall of the box body 1. There are also a plurality of adjusting screws 62, and the plurality of adjusting screws 62 are respectively rotatably installed inside the plurality of sliding grooves 65. The bottom ends of the side walls of the plurality of adjusting screws 62 are fixedly installed with driven gears 63 of different heights. The output shaft of the driving motor 61 is fixedly installed with a plurality of stacked driving gears 67, and the heights of the plurality of driving gears 67 are respectively aligned with the heights of the plurality of driven gears 63. There are a plurality of transmission chains 64, and two driving gears 67 and the driven gear 63 on the same plane are connected through the transmission chain 64. There are a plurality of connecting slide plates 66 , multiple fixedly mounted on the side wall of the support plate 31, multiple connecting slide plates 66 are respectively located inside the multiple sliding grooves 65, and multiple connecting slide plates 66 are threadedly mounted on the side walls of multiple adjusting screws 62; by controlling the drive motor 61 to work, the output end of the drive motor 61 works, and through the transmission of the driven gear 63, the transmission chain 64 and the drive gear 67, the multiple adjusting screws 62 rotate in the same direction, so that the connecting slide plates 66 move up and down inside the sliding grooves 65, thereby adjusting the height of the support plate 31, and the part of the diffusion plate 32 inside the box body 1 is adjusted synchronously with the height of the support plate 31. When there are fewer items placed inside the box body 1, the space inside the diffusion plate 32 is reduced by moving the support plate 31 upward, so that the liquid nitrogen sprayed from the diffusion plate 32 can be more concentratedly distributed around the items, thereby increasing the freezing speed of the items and reducing the loss of liquid nitrogen. ;

[0023] like Figures 2-8As shown, in one embodiment, a support assembly is provided inside the box body 1. The support assembly includes a positioning groove 41, a support bar 42, a limit seat 44, and a strong magnetic plate 45. There are multiple positioning grooves 41, and the multiple positioning grooves 41 are equidistantly formed on the top wall surface of the support plate 31. There are also multiple support bars 42, and the multiple support bars 42 are respectively slidably installed inside the multiple positioning grooves 41. Multiple ventilation holes 43 are formed on the side walls of the multiple support bars 42. The strong magnetic plate 45 is fixedly installed on the inner bottom wall surface of the box body 1, and the side wall surfaces of the strong magnetic plate 45 and the support bar 42 that are close to each other have the same magnetic poles. By providing the support bar 42 on the top of the support plate 31, the article placed on the top of the support plate 31 is supported by the support bar 42, the gap between the article and the top wall surface of the support plate 31 is increased, facilitating the contact between the liquid nitrogen and the bottom wall surface of the article. The liquid nitrogen on the top of the support plate 31 can flow through the ventilation holes 43, enabling the liquid nitrogen to be more evenly distributed at the bottom of the article. When the support bar 42 moves downward together with the support plate 31, due to the repulsion between the same magnetic poles, the shorter the distance between the support bar 42 and the strong magnetic plate 45, the stronger the repulsive force received by the support bar 42, so it will move upward, increasing the space for the liquid nitrogen to flow at the bottom of the article. The space for the liquid nitrogen to flow on the top of the support plate 31 can be adjusted at any time according to the article placed on the top of the support plate 31. The limit seat 44 is fixedly installed on the bottom wall surface of the support bar 42. The movement range of the support bar 42 is restricted by the limit seat 44 to prevent the support bar 42 from detaching from the inside of the support plate 31.

[0024] As Figures 2-6As shown, in one embodiment, a closing assembly is provided at the top of the box body 1. The closing assembly includes fixed legs 51, a sealing cloth 53, positioning blocks 54, ejector rods 56 and connecting ropes 57. There are four fixed legs 51 in total. The four fixed legs 51 are divided into two groups and are fixedly installed at the left and right ends of the top wall surface of the box body 1 in a mirror image. A rotating shaft 52 is rotatably installed between two adjacent fixed legs 51. Limiting grooves 55 are provided on the front and rear side walls inside the top sandwich layer of the box body 1. There are two sealing cloths 53 in total. The two sealing cloths 53 are respectively fixedly installed at the left and right ends of the top wall surface of the diffusion plate 32. One ends of the two sealing cloths 53 away from the diffusion plate 32 bypass the side wall of the rotating shaft 52 and extend downward into the inside of the top sandwich layer of the box body 1. The front and rear ends of the sealing cloth 53 are respectively located inside the adjacent limiting grooves 55. The top end of the upper spraying groove 35 is covered by the sealing cloth 53 to limit the downward distribution range of liquid nitrogen. Since the diffusion plate 32 is fixedly installed on the side wall of the support plate 31, the diffusion plate 32 will move downward synchronously with the support plate 31. When the diffusion plate 32 moves downward, the two sealing cloths 53 will be drawn out from the inside of the box body 1. A gap will be generated at the adjacent ends of the two sealing cloths 53. The liquid nitrogen inside the upper sandwich layer of the box body 1 can only diffuse downward through the upper spraying groove 35 near the middle, concentrating the liquid nitrogen at the middle position inside the box body 1. When an item is placed at the middle position on the top of the support plate 31, the freezing of the item can be further accelerated. When more items are placed on the top of the support plate 31, as the support plate 31 moves downward, the more the diffusion plate 32 pulls out the sealing cloth 53, and the larger the diffusion range of the liquid nitrogen inside the upper sandwich layer of the box body 1, which facilitates the adjustment of the device according to the distribution range of the items. There are multiple positioning blocks 54 in total. The multiple positioning blocks 54 are respectively fixedly installed on the front and rear side walls of the two sealing cloths 53, and the positioning blocks 54 are slidably installed inside the limiting grooves 55. There are two ejector rods 56 in total. The two ejector rods 56 are distributed at the front and rear ends of the top of the box body 1, and the bottom ends of the two ejector rods 56 slidably penetrate the top wall surface of the box body 1 and are fixedly installed on the top wall surface of the support plate 31. There are also two connecting ropes 57. Grooves for accommodating the connecting ropes 57 are provided on the side walls of the ejector rods 56. The two ends of the two connecting ropes 57 are respectively fixedly connected to the side walls of the adjacent two positioning blocks 54. The two sealing cloths 53 are connected by the connecting ropes 57. When the support plate 31 moves upward, the ejector rods 56 move synchronously with the support plate 31. Therefore, the ejector rods 56 can push the connecting ropes 57 upward. The two ends of the connecting ropes 57 pull the two sealing cloths 53 to move toward the inside of the box body 1, so that the sealing cloth 53 can re-seal the top end of the upper spraying groove 35. The sealing cloth 53 and the connecting ropes 57 are both made of polyurethane / rubber composite materials. By utilizing the characteristics of the polyurethane / rubber composite materials, the sealing cloth 53 and the connecting ropes 57 can deform at low temperatures, avoiding the situation that the sealing cloth 53 and the connecting ropes 57 are damaged due to the too low internal temperature of the box body 1.

[0025] Embodiment Two This embodiment discloses a quick-freezing method for an intelligent molecular quick-freezing storage, including the following steps: First step: Open the box door 7, place the items to be quick-frozen on the top of the support bar 42, control the driving motor 61 to work according to the height of the items, so that the output end of the driving motor 61 rotates. Driven by the driven gear 63, the transmission chain 64 and the driving gear 67, the adjusting screw 62 rotates, and the support plate 31 moves upward or downward to adjust the space for placing items at the top of the support plate 31; Second step: When the support plate 31 moves downward, the sealing cloth 53 is pulled out from the inside of the box body 1 as the diffusion plate 32 moves downward, increasing the gap between the two sealing cloths 53. Since the distance between the support plate 31 and the strong magnetic plate 45 shortens, the repulsive force on the support bar 42 becomes stronger, and the support bar 42 moves upward accordingly; Third step: When the support plate 31 moves upward, the distance between the support plate 31 and the top end inside the box body 1 shortens, the repulsive force on the support bar 42 becomes weaker, the distance between the items at the top of the support bar 42 and the top wall surface of the support plate 31 decreases, and the ejector rod 56 moves upward together with the support plate 31. Therefore, the ejector rod 56 pushes the connecting rope 57, causing the two ends of the connecting rope 57 to approach the ejector rod 56. Thus, the two ends of the connecting rope 57 pull the two sealing cloths 53 to move toward the adjacent side, shortening the gap between the two sealing cloths 53; Fourth step: Close the box door 7, then open the external liquid nitrogen tank. The liquid nitrogen enters the liquid nitrogen evaporator, and the liquid nitrogen is atomized by the liquid nitrogen evaporator and sent into the inside of the connecting pipe 33. The liquid nitrogen is sent into the inside of the diffusion plate 32 and respectively sent into the upper spray tank 35, the lower spray tank 36 and the inside of the box body 1 through multiple spray holes on the diffusion plate 32, so that the liquid nitrogen is ejected from the upper, lower, left, right and rear sides of the items to quickly freeze the items placed on the top of the support bar 42.
