[0002] As people's living standards continue to improve, their pursuit of food quality is also getting higher and higher. In order to store some foods for a longer time, transport them further, and keep them fresh and safe, quick-freezing storage is required to quickly freeze the foods.

[0003] After searching, the Chinese patent publication number is CN209512352U, which discloses an intelligent molecular quick-freezing storage, including a molecular quick-freezing storage body with an insulation layer, a refrigeration source placed outside the molecular quick-freezing storage body, a detection unit, an artificial intelligence control system, and an environmental parameter control component; the environmental parameter control component includes a spray evaporator and a quick-freezing storage circulating air unit; a quick-freezing door is provided on the molecular quick-freezing storage body, and a spray evaporator is installed on the side of the inner wall of the molecular quick-freezing storage body except for the side on which the quick-freezing door is provided; a quick-freezing storage circulating air unit is installed on the top surface of the molecular quick-freezing storage body, and the refrigeration source is connected to the spray evaporator through a pipeline; a detection unit is installed in the molecular quick-freezing storage body; the intelligent control system is connected to the above-mentioned detection unit, environmental parameter control component and refrigeration source; the intelligent control system controls the operation of the components connected thereto to cool the quick-freezing storage and 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, and then the material rack is placed in the quick-freezing room, and then the liquid nitrogen in the liquid nitrogen tank is sent to the liquid nitrogen evaporator, so that the liquid nitrogen is sprayed into the quick-freezing room to cool the items. However, in actual use, since the space of the quick-freezing room is fixed, and the number of items to be quick-frozen each time is often not fixed, when there are fewer quick-frozen items, more liquid nitrogen is sent into the quick-freezing room, and the liquid nitrogen cannot be fully used, which easily causes a waste of liquid nitrogen; when there are more quick-frozen items, the liquid nitrogen sent into the quick-freezing room is relatively less, and the quick-freezing of the items in the quick-freezing room becomes slower, affecting the quick-freezing efficiency. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention proposes an intelligent molecular quick-freezing storage and quick-freezing method. By controlling the operation of the driving motor, the output end of the driving motor is operated, and through the transmission of the driven gear, the transmission chain and the driving gear, multiple adjusting screws are rotated in the same direction, so that the connecting slide moves up and down inside the sliding groove, and the height of the support plate is adjusted. By moving the support plate upward, the space inside the box where the diffusion plate is located is reduced, so that the liquid nitrogen sprayed from the diffusion plate can be more concentratedly distributed around the items, thereby improving the freezing speed of the items and reducing the loss of liquid nitrogen.

The position of the partition plate is aligned with the top wall of the box body, and the partition plate is in contact with the inner wall of the diffuser plate.

[0017] In some embodiments, a plurality of spray holes are provided on the side wall of the diffuser plate, and the plurality of spray holes on the diffuser plate are distributed with the aperture becoming larger as they approach the bottom. An upper connecting groove is provided on the inner rear side wall of the upper spray groove, and lower connecting grooves are provided on the left and right side walls of the support plate.

[0018] In some embodiments, a support assembly is provided inside the box, and the support assembly includes:

[0019] Positioning grooves and support bars, wherein the positioning grooves are equidistantly provided on the top wall of the support plate, and the support bars are slidably installed inside the plurality of positioning grooves;

[0020] A strong magnetic plate is fixedly mounted on the inner bottom wall of the box, and the magnetic poles of the wall on one side close to the strong magnetic plate and the support bar are the same.

[0021] In some embodiments, the support assembly further comprises:

[0022] The limiting seat is fixedly installed on the bottom wall of the supporting bar.

[0023] In some embodiments, a plurality of ventilation holes are formed on the side walls of the support bar.

[0024] In some embodiments, a closing assembly is provided on the top of the box, and the closing assembly includes:

[0025] There are four fixed legs in total. The four fixed legs are divided into two groups and fixedly mounted on the left and right ends of the top wall of the box in a mirror-image manner. A rotating shaft is rotatably installed between two adjacent fixed legs. Limiting grooves are provided on the front and rear walls of the top interlayer of the box;

[0026] There are two sealing cloths, which are respectively fixed on the left and right ends of the top wall of the diffuser plate. The ends of the two sealing cloths away from the diffuser plate bypass the side walls of the rotating shaft and extend downward into the interior of the top interlayer of the box body. The front and rear ends of the sealing cloths are respectively located in the adjacent limit grooves.

[0027] In certain embodiments, the closure assembly further comprises:

[0028] There are multiple positioning blocks, top rods and connecting ropes. The multiple positioning blocks are respectively fixedly mounted on the front and rear side walls of the two sealing cloths. The top rod is arranged on the top of the box body. The bottom end of the top rod slides through the top wall of the box body. The bottom end of the top rod is fixedly mounted on the top wall of the support plate. The two ends of the connecting rope are respectively fixedly connected to the side walls of the two adjacent positioning blocks. A groove for accommodating the connecting rope is opened on the side wall of the top rod.

[0029] A quick-freezing method for an intelligent molecular quick-freezing library comprises the following steps:

[0030] Step 1: Open the door and place the items to be quick-frozen on the top of the support bar. Control the drive motor according to the height of the items to rotate the output end of the drive motor. Under the transmission of the driven gear, transmission chain and drive gear, the adjusting screw rotates to move the support plate up or down to adjust the space on the top of the support plate for placing items.

[0031] Step 2: When the support plate moves downward, the sealing cloth is pulled out from the inside of the box as the diffuser plate moves downward, increasing the gap between the two sealing cloths. As the distance between the support plate and the strong magnetic plate shortens, the repulsive force on the support bar becomes stronger, causing the support bar to move upward;

[0032] Step 3: When the support plate moves upward, the distance between the support plate and the top of the box body is shortened, the repulsive force on the support bar is weakened, and the distance between the items on the top of the support bar and the top wall of the support plate is reduced. The top rod moves upward with the support plate, and the top rod pushes the connecting rope, so that the two ends of the connecting rope move closer to the top rod. The two ends of the connecting rope therefore pull the two sealing cloths to move closer to each other, shortening the gap between the two sealing cloths;

[0033] Step 4: Close the door of the box, then open the external liquid nitrogen tank, and the liquid nitrogen enters the liquid nitrogen evaporator. The liquid nitrogen is made into mist through the liquid nitrogen evaporator and sent into the inside of the connecting pipe. The liquid nitrogen is sent into the inside of the diffusion plate, and then sent into the upper spray trough, lower spray trough and the inside of the box through multiple nozzles on the diffusion plate. The liquid nitrogen is sprayed from five directions: top, bottom, left, right and back of the items, and the items placed on the top of the support bar are quickly frozen.

[0034] Compared with the prior art, the present invention has the following significant advantages:

[0035] First, the present invention connects the output end of the external liquid nitrogen tank with the input end of the liquid nitrogen evaporator, and then connects the output end of the liquid nitrogen evaporator with the top ends of multiple connecting pipes, so that the liquid nitrogen is sent into the interior of the diffusion plate and is respectively sent into the upper spray slot, the lower spray slot and the interior of the box through multiple spray holes on the diffusion plate, so as to quickly freeze the objects placed on the top of the support plate; by controlling the operation of the driving motor, the output end of the driving motor is operated, and through the transmission of the driven gear, the transmission chain and the driving gear, the multiple adjusting screws are rotated in the same direction, so that the connecting slide plate moves up and down inside the sliding slot, thereby adjusting the height of the support plate, and the part of the diffusion plate inside the box is synchronously adjusted with the height of the support plate. When there are fewer objects placed inside the box, the support plate is moved upward to reduce the space inside the box where the diffusion plate is located, so that the liquid nitrogen sprayed from the diffusion plate can be more concentratedly distributed around the objects, thereby improving the freezing speed of the objects and reducing the loss of liquid nitrogen; and solves the problem of low utilization rate of liquid nitrogen in existing quick-freezing warehouses.

[0036] Second, the present invention fixes the position of the connecting pipe by means of a fixing bar and a fixing frame, and then divides the interior of the diffusion plate into two parts by means of a partition plate. At the same time, by fitting the partition plate to the inner side wall of the diffusion plate, the sliding of the diffusion plate is not hindered. Since the bottom end of the connecting pipe is inside the box, the liquid nitrogen output from the bottom end of the connecting pipe can only be inside the box, thereby preventing the liquid nitrogen from spraying out of the top of the box.

[0037] Thirdly, the present invention provides support bars on the top of the support plate, and utilizes the support bars to support the articles placed on the top of the support plate, thereby increasing the gap between the articles and the top wall of the support plate, facilitating the contact between the liquid nitrogen and the bottom wall of the articles, and allowing the liquid nitrogen on the top of the support plate to circulate through the ventilation holes, so that the liquid nitrogen can be more evenly distributed on the bottom of the articles. When the support bars move downward with the support plate, due to the mutual repulsion of the same magnetic poles, the shorter the distance between the support bars and the strong magnetic plate, the stronger the repulsive force on the support bars, and therefore the support bars will move upward, thereby increasing the space for the liquid nitrogen to flow at the bottom of the articles. The space for the liquid nitrogen to flow on the top of the support plate can be adjusted at any time according to the articles placed on the top of the support plate.

[0038] Fourthly, the present invention covers the top of the upper spray slot with a sealing cloth to limit the downward distribution range of the liquid nitrogen. The diffusion plate will move downward synchronously with the support plate to pull the two sealing cloths out from the interior of the box. The gap at the adjacent ends of the two sealing cloths will expand, and the two sealing cloths will be connected by a connecting rope. When the support plate moves upward, the top rod moves synchronously with the support plate, so that the top rod can push the connecting rope upward. The two ends of the connecting rope pull the two sealing cloths toward the interior of the box, so that the sealing cloth can re-seal the top of the upper spray slot, making it convenient for the device to adjust the range of liquid nitrogen discharge from the top according to the number of items.

[0051] The present invention provides an intelligent molecular quick-freezing library and quick-freezing method through improvement. The technical solution of the present invention is:

[0052] Example 1

[0053] like 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 component extending outside the box body 1 is arranged inside the box body 1. The diffusion component includes a support plate 31, a diffusion plate 32, a connecting pipe 33, a fixing strip 341, a fixing bracket 342, a partition plate 343, an upper spraying groove 35 and a lower spraying 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 spraying holes are formed on the side wall of the diffusion plate 32. The plurality of spraying holes on the diffusion plate 32 are distributed such that the hole diameter is larger closer 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 spraying grooves 35 and a plurality of lower spraying grooves 36. The plurality of upper spraying grooves 35 and the plurality of lower spraying grooves 36 are respectively formed on the inner top wall surface of the box body 1 and the top wall surface of the support plate 31. The upper spraying groove 35 and the lower spraying 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 formed on the rear side wall surface inside the upper spraying 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 formed 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. Feed the liquid nitrogen into the inside of the diffusion plate 32, and send it into the upper spraying groove 35, the lower spraying groove 36 and the inside of the box body 1 through the plurality of spraying 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 bracketThe 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 66. The driving motor 61 is fixedly mounted on the bottom end of the side wall of the box body 1. There are multiple sliding grooves 65, and multiple sliding grooves 65 are respectively opened on the inner wall of the box body 1. There are also multiple adjusting screws 62, and multiple adjusting screws 62 are respectively rotatably mounted inside the multiple sliding grooves 65. The bottom ends of the side walls of the multiple adjusting screws 62 are fixedly mounted with driven gears 63 of different heights. The output shaft of the driving motor 61 is fixedly mounted with multiple stacked driving gears 67, and the heights of the multiple driving gears 67 are respectively aligned with the heights of the multiple driven gears 63. There are multiple transmission chains 64, and the two driving gears 67 and the driven gear 63 on the same plane are connected through the transmission chain 64. There are multiple connecting slides 66 , multiple fixedly mounted on the side walls of the support plate 31, multiple connecting slides 66 are respectively located inside the multiple sliding grooves 65, and multiple connecting slides 66 are threadedly mounted on the side walls of the multiple adjusting screws 62; by controlling the operation of the drive motor 61, the output end of the drive motor 61 is operated, and through the transmission of the driven gear 63, the transmission chain 64 and the drive gear 67, the multiple adjusting screws 62 are rotated in the same direction, so that the connecting slides 66 move up and down inside the sliding grooves 65, thereby adjusting the height of the support plate 31. 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 support plate 31 is moved upward to reduce the space inside the box body 1 for the diffusion plate 32, 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.

[0054] like Figure 2-Figure 8As shown, in one embodiment, a support assembly is provided inside the box body 1, and the support assembly includes a positioning slot 41, a support bar 42, a limit seat 44 and a strong magnetic plate 45. There are a plurality of positioning slots 41, and a plurality of positioning slots 41 are equidistantly arranged on the top wall of the support plate 31. There are also a plurality of support bars 42, and a plurality of support bars 42 are slidably installed inside the plurality of positioning slots 41 respectively. A plurality of ventilation holes 43 are provided on the side walls of the plurality of support bars 42. The strong magnetic plate 45 is fixedly installed on the inner bottom wall of the box body 1, and the magnetic poles of the side wall close to the strong magnetic plate 45 and the support bar 42 are the same; by arranging the support bar 42 on the top of the support plate 31, the support bar 42 is used to support the items placed on the top of the support plate 31, thereby improving the connection between the items and the top of the support plate 31 The gap between the walls facilitates the contact between the liquid nitrogen and the bottom wall of the object. The liquid nitrogen on the top of the support plate 31 can circulate through the ventilation holes 43, so that the liquid nitrogen can be more evenly distributed on the bottom of the object. When the support bar 42 moves downward with the support plate 31, due to the mutual repulsion of the same magnetic poles, the shorter the distance between the support bar 42 and the strong magnetic plate 45, the stronger the repulsive force on the support bar 42, so it will move upward, increasing the space for the liquid nitrogen to flow at the bottom of the object. 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 object placed on the top of the support plate 31; the limit seat 44 is fixedly installed on the bottom wall of the support bar 42; the limit seat 44 limits the movement range of the support bar 42 to prevent the support bar 42 from detaching from the inside of the support plate 31.

[0055] like Figure 2-Figure 6As shown, in one embodiment, a closing assembly is provided on the top of the box body 1, and the closing assembly includes a fixed leg 51, a sealing cloth 53, a positioning block 54, a top rod 56 and a connecting rope 57. There are four fixed legs 51 in total, and the four fixed legs 51 are divided into two groups and fixedly mounted on the left and right ends of the top wall of the box body 1 in a mirror-image manner. A rotating shaft 52 is rotatably mounted between two adjacent fixed legs 51. Limiting grooves 55 are provided on the front and rear side walls of the interior of the top interlayer of the box body 1. There are two sealing cloths 53 in total, and the two sealing cloths 53 are fixedly mounted on the left and right ends of the top wall of the diffuser plate 32 respectively. The ends of the two sealing cloths 53 away from the diffuser plate 32 bypass the side wall of the rotating shaft 52 and extend downward into the interior of the top interlayer of the box body 1. The front and rear ends of the sealing cloth 53 are respectively The top of the upper spray slot 35 is covered by the sealing cloth 53 to limit the range of the liquid nitrogen distributed downward. Since the diffusion plate 32 is fixedly mounted 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 pulled out from the inside of the box body 1. A gap is therefore created at one end of the two sealing cloths 53 that are close to each other. The liquid nitrogen inside the upper interlayer of the box body 1 can only diffuse downward through the upper spray slot 35 close to the middle, concentrating the liquid nitrogen in the middle position inside the box body 1. When an object is placed in the middle position on the top of the support plate 31, the freezing of the object can be further accelerated. When more objects are placed on the top of the support plate 31, the upward movement of the support plate 31 The more the diffusion plate 32 pulls out the sealing cloth 53, the larger the range of diffusion of the liquid nitrogen inside the top interlayer of the box body 1 is, so that the device can be adjusted according to the distribution range of the items. There are a plurality of positioning blocks 54, which are fixedly mounted on the front and rear side walls of the two sealing cloths 53, and the positioning blocks 54 are slidably mounted inside the limiting grooves 55. There are two top rods 56, which are distributed at the front and rear ends of the top of the box body 1, and the bottom ends of the two top rods 56 slide through the top wall of the box body 1, and the bottom ends of the top rods 56 are fixedly mounted on the top wall of the support plate 31. There are also two connecting ropes 57, and the side walls of the top rods 56 are provided with grooves for accommodating the connecting ropes 57. The two connecting ropes 57 are fixedly mounted on the top wall of the support plate 31. The two ends of 7 are respectively fixedly connected to the side walls of two adjacent positioning blocks 54; the two sealing cloths 53 are connected by a connecting rope 57. When the support plate 31 moves upward, the top rod 56 moves synchronously with the support plate 31, and the top rod 56 can therefore push the connecting rope 57 to move upward. The two ends of the connecting rope 57 pull the two sealing cloths 53 toward the inside of the box body 1, so that the sealing cloth 53 can re-seal the top of the upper spray groove 35; the sealing cloth 53 and the connecting rope 57 are both made of polyurethane / rubber composite material; by utilizing the characteristics of the polyurethane / rubber composite material, the sealing cloth 53 and the connecting rope 57 can be deformed at low temperature, thereby avoiding the situation where the sealing cloth 53 and the connecting rope 57 are damaged due to the internal temperature of the box body 1 being too low.

[0056] Example 2

[0057] This embodiment discloses a quick-freezing method for an intelligent molecular quick-freezing library, comprising the following steps:

[0058] Step 1: Open the door 7 and place the items to be quick-frozen on the top of the support bar 42. Control the drive motor 61 according to the height of the items, so that the output end of the drive motor 61 rotates. Under the transmission of the driven gear 63, the transmission chain 64 and the drive gear 67, the adjustment screw 62 rotates, so that the support plate 31 moves upward or downward, and the space on the top of the support plate 31 that can be used to place items is adjusted;

[0059] Step 2: When the support plate 31 moves downward, the sealing cloth 53 is pulled out from the interior of the box body 1 as the diffuser plate 32 moves downward, increasing the gap between the two sealing cloths 53. As the distance between the support plate 31 and the strong magnetic plate 45 decreases, the repulsive force on the support bar 42 becomes stronger, causing the support bar 42 to move upward.

[0060] Step 3: When the support plate 31 moves upward, the distance between the support plate 31 and the top of the box body 1 is shortened, the repulsive force on the support bar 42 is weakened, and the distance between the items on the top of the support bar 42 and the top wall of the support plate 31 is shortened. The top rod 56 moves upward together with the support plate 31, and the top rod 56 pushes the connecting rope 57, so that the two ends of the connecting rope 57 move closer to the top rod 56. The two ends of the connecting rope 57 therefore pull the two sealing cloths 53 to move closer to each other, shortening the gap between the two sealing cloths 53;

[0061] Step 4: Close the door 7, then open the external liquid nitrogen tank, and allow the liquid nitrogen to enter the liquid nitrogen evaporator. The liquid nitrogen is transformed into mist by the liquid nitrogen evaporator and sent into the interior of the connecting pipe 33. The liquid nitrogen is sent into the interior of the diffuser plate 32, and then sent into the upper spray slot 35, the lower spray slot 36 and the interior of the box body 1 through multiple spray holes on the diffuser plate 32. The liquid nitrogen is sprayed from five directions: the top, bottom, left, right and rear sides of the objects, and the objects placed on the top of the support bar 42 are quickly frozen.

[0062] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.

7. A quick freezing method applied to the intelligent molecular quick freezing storehouse according to claim 6, characterized in that: The following steps are involved: Step 1: Open the door (7), place the items to be quick-frozen on the top of the support bar (42), control the drive motor (61) to work according to the height of the items, rotate the output end of the drive motor (61), and rotate the adjustment screw (62) under the transmission of the driven gear (63), the transmission chain (64) and the drive gear (67), so that the support plate (31) moves upward or downward, and adjusts the space on the top of the support plate (31) for placing items; Step 2: When the support plate (31) moves downward, the sealing cloth (53) is pulled out from the interior of the box (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) is shortened, the repulsive force on the support bar (42) becomes stronger, and the support bar (42) therefore moves upward; Step 3: When the support plate (31) moves upward, the distance between the support plate (31) and the top of the box body (1) is shortened, the repulsive force on the support bar (42) becomes weaker, and the distance between the items on the top of the support bar (42) and the top wall of the support plate (31) is shortened. The top rod (56) moves upward together with the support plate (31), and the top rod (56) pushes the connecting rope (57) so that the two ends of the connecting rope (57) are close to the top rod (56). The two ends of the connecting rope (57) therefore pull the two sealing cloths (53) to move toward the adjacent side, shortening the gap between the two sealing cloths (53); Step 4: Close the door (7) and then open the external liquid nitrogen tank. The liquid nitrogen enters the liquid nitrogen evaporator and is misted by the liquid nitrogen evaporator and sent to the inside of the connecting pipe (33). The liquid nitrogen is sent to the inside of the diffusion plate (32). Through the multiple spray holes on the diffusion plate (32), the liquid nitrogen is sent to the upper spray slot (35), the lower spray slot (36) and the inside of the box (1). The liquid nitrogen is sprayed from the top, bottom, left, right and rear sides of the objects to quickly freeze the objects placed on the top of the support bar (42).
