Description

Technical Field

[0001] This utility model relates to the field of food storage technology, specifically to a food moisture-proof and fresh-keeping storage device. Background Technology

[0002] Food refers to substances that can be consumed or drunk by humans, including processed food, semi-finished products, and unprocessed food. In a home environment, food exposed to moisture will oxidize or become damp. When food becomes damp, microorganisms will multiply, oxidation will occur, and mold will grow, causing the food to spoil. When food is not stored, the high activity of enzymes, the excessively fast oxidation rate, and the problem of microbial contamination will affect the freshness of the food itself. Therefore, foods such as leftover sunflower seeds, French fries, or peanuts need to be stored.

[0003] While existing storage devices offer numerous advantages during use, they still suffer from the following problems: they cannot adjust the storage space according to the storage volume, resulting in excessive air being incorporated into the food during storage, which negatively impacts the food storage environment and affects the food storage effect. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a food moisture-proof and fresh-keeping storage device.

[0005] The technical solution adopted by this utility model to solve its technical problem is a food moisture-proof and fresh-keeping storage device, including a storage box, a cover plate and a bearing. The upper outer wall of the storage box is provided with a cover plate, and the bearing is interference-fitted inside the cover plate. The inner ring of the bearing is interference-fitted with a rotating shaft, and the lower outer wall of the rotating shaft is screwed with a threaded post. The bottom of the storage box is provided with a material support plate, and the upper outer wall of the material support plate is threaded with a rectangular array of vent pipes. The vent pipes have equidistant parallel vent holes inside.

[0006] By adopting the above technical solution, the vent pipe and vent holes can increase the gas exchange area of ​​the food inside the storage box, ensuring gas exchange between the stacked food, avoiding localized moisture accumulation, and improving the food storage effect. By rotating the shaft, the staff can drive the support plate to move vertically inside the storage box in conjunction with the threaded column and threaded sleeve, adjusting the position of the support plate inside the storage box to ensure that the storage space inside the storage box is adapted to the required storage amount, reducing the amount of moisture inside the storage box, reducing the impact of external gases on the food, and ensuring the storage quality of the food.

[0007] Specifically, the outer wall of the storage box is bonded with a rectangular array of card blocks, and the outer wall of the cover is bonded with a rectangular array of card sleeves. The card sleeves are connected to buckles by pins inside, and the buckles are engaged with the card blocks.

[0008] By adopting the above technical solution, the connection between the cover and the storage box can be ensured through the snap-fit ​​and snap-fit ​​force between the buckle and the buckle block, and the ease of disassembly and assembly of the cover can be ensured. The combination between the cover and the storage box can ensure the sealing of the inside of the storage box. Before disassembling the cover, the staff first unlocks the buckle and manually rotates the shaft to disengage the threaded column from the inside of the threaded sleeve, so that the cover can be disassembled.

[0009] Specifically, a feed inlet is provided on one side of the outer wall of the upper end of the cover plate, and a rubber plug is provided on the upper end of the inner wall of the feed inlet.

[0010] By adopting the above technical solution, users can put food into the cover through the inlet, or pour out the food by tilting the storage box to orient the inlet. The rubber plug can block the inlet, ensuring the airtightness of the storage box and achieving the purpose of food moisture prevention.

[0011] Specifically, a gas supply pipe is threadedly connected to one side of the upper outer wall of the cover plate, and a quick connector is threadedly connected to the upper outer wall of the gas supply pipe.

[0012] By adopting the above technical solution, users can connect the pipeline of the external nitrogen tank to the quick connector, thereby introducing nitrogen into the storage box through the gas supply pipe to replace the air inside the storage box, further reducing the moisture content inside the storage box, and achieving the purpose of food preservation through nitrogen.

[0013] Specifically, a handle is screwed to the outer wall of the upper end of the shaft, and the handle is located on the outer wall of the upper end of the cover plate.

[0014] By adopting the above technical solution, the user can easily rotate the shaft through the handle to make it rotate in a circular motion, thereby driving the threaded column to rotate accordingly.

[0015] Specifically, the upper outer wall of the bearing plate is integrally formed with a threaded sleeve, the threaded column is threadedly connected to the inside of the threaded sleeve, and a sealing ring is bonded and fixed to one side of the outer wall of the rotating shaft, the sealing ring being located at the upper end of the threaded column.

[0016] By adopting the above technical solution, the material receiving plate can be raised and lowered by rotating the handle through the cooperation of the threaded sleeve and the threaded column, thereby adjusting the storage space inside the storage box and reducing air residue. The sealing ring can block the gap between the rotating shaft and the threaded sleeve, preventing food from entering the threaded sleeve. The gap between the sealing ring and the threaded sleeve is 0.2mm, so the threaded sleeve will not cause wear to the sealing ring.

[0017] Specifically, a sealing gasket is bonded and fixed to the outer wall of the material support plate, and the sealing gasket is in contact with the inner wall of the storage box.

[0018] By adopting the above technical solution, the sealing gasket ensures the sealing between the material support plate and the storage box, ensures the sealing of the storage environment inside the storage box, and when the material support plate is removed from the storage box, the sealing gasket can scrape and clean the residual material adhering to the inner wall of the storage box.

[0019] The beneficial effects of this utility model are:

[0020] The food moisture-proof and fresh-keeping storage device of this utility model can drive the material support plate to move vertically inside the storage box by rotating the shaft, which works in conjunction with the threaded column and threaded sleeve. This adjusts the position of the material support plate inside the storage box, ensuring that the storage space inside the storage box is adapted to the required storage amount, reducing the amount of moisture inside the storage box, reducing the impact of external gases on the food, and ensuring the storage quality of the food.

[0021] The food moisture-proof and fresh-keeping storage device of this utility model can realize the lifting and lowering of the material receiving plate through the cooperation of the threaded sleeve and the threaded column, thereby adjusting the storage space inside the storage box and reducing residual air. It can also introduce nitrogen into the storage box through the gas supply pipe to replace the air inside the storage box, further reducing the moisture content inside the storage box, and achieving the purpose of food preservation through nitrogen.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the food moisture-proof and freshness-preserving storage device of this utility model includes a storage box 1, a cover plate 2, and a bearing 3. The upper outer wall of the storage box 1 is provided with a cover plate 2, and the bearing 3 is interference-fitted inside the cover plate 2. The inner ring of the bearing 3 is interference-fitted with a rotating shaft 31. The lower outer wall of the rotating shaft 31 is screwed with a threaded post 33. The bottom of the storage box 1 is provided with a material support plate 11. The upper outer wall of the material support plate 11 is threaded with a rectangular array of vent pipes 14. The vent pipes 14 have equidistant parallel vent holes 15 inside.

[0031] In use, the vent pipe 14, together with the vent hole 15, can realize the gas exchange area of ​​the food inside the storage box 1, ensure gas exchange between the stacked food, avoid local moisture accumulation, and improve the food storage effect. By rotating the shaft 31, the operator can drive the support plate 11 to move vertically inside the storage box 1 in conjunction with the threaded column 33 and the threaded sleeve 13, and adjust the position of the support plate 11 inside the storage box 1. This ensures that the storage space inside the storage box 1 is adapted to the required storage amount, reduces the amount of moisture inside the storage box 1, reduces the impact of external gas on the food, and ensures the food storage quality.

[0032] To maintain connection strength, for example, such as Figure 4 As shown, the outer wall of the storage box 1 is glued with a rectangular array of card blocks 16, and the outer wall of the cover plate 2 is glued with a rectangular array of card sleeves 25. The card sleeve 25 is connected to a buckle 26 by a pin, and the buckle 26 is engaged with the card block 16.

[0033] During use, the locking force between the buckle 26 and the locking block 16 ensures the stability of the connection between the cover plate 2 and the storage box 1, and also ensures the ease of disassembly and assembly of the cover plate 2. The connection between the cover plate 2 and the storage box 1 ensures the airtightness of the storage box 1. Before disassembling the cover plate 2, the operator first unlocks the buckle 26 and manually rotates the shaft 31 to disengage the threaded post 33 from the threaded sleeve 13, thereby enabling the disassembly of the cover plate 2.

[0034] For example, for feeding, such as Figure 4 As shown, a feed inlet 23 is provided on one side of the outer wall of the upper end of the cover plate 2, and a rubber plug 24 is provided on the upper end of the inner wall of the feed inlet 23.

[0035] In use, the user can put food into the cover plate 2 through the feed inlet 23, or pour out the food by tilting the storage box 1 so that the feed inlet 23 faces the direction. The rubber plug 24 can block the feed inlet 23 to ensure the airtightness of the storage box 1 and achieve the purpose of food moisture prevention.

[0036] For gas replacement, exemplarily, such as Figure 4 As shown, a gas supply pipe 21 is threadedly connected to one side of the upper outer wall of the cover plate 2, and a quick connector 22 is threadedly connected to the upper outer wall of the gas supply pipe 21.

[0037] When in use, the user can connect the pipeline of the external nitrogen tank to the quick connector 22, so that nitrogen can be introduced into the storage box 1 through the gas supply pipe 21 to replace the air inside the storage box 1, further reducing the moisture content inside the storage box 1, and achieving the purpose of food preservation through nitrogen.

[0038] To drive rotation, for example, such as Figure 5 As shown, a handle 32 is screwed to the outer wall of the upper end of the rotating shaft 31, and the handle 32 is located on the outer wall of the upper end of the cover plate 2.

[0039] When in use, the user can easily rotate the shaft 31 by using the handle 32 to make it rotate in a circular motion, thereby driving the threaded column 33 to rotate accordingly.

[0040] For position adjustment, for example, such as Figure 5 As shown, a threaded sleeve 13 is integrally formed on the outer wall of the upper end of the material support plate 11, and a threaded column 33 is threadedly connected to the inside of the threaded sleeve 13. A sealing ring 34 is bonded and fixed on one side of the outer wall of the rotating shaft 31, and the sealing ring 34 is located at the upper end of the threaded column 33.

[0041] During use, by rotating the handle 32, the material receiving plate 11 can be raised and lowered through the cooperation of the threaded sleeve 13 and the threaded post 33, thereby adjusting the storage space inside the storage box 1 and reducing air residue. The sealing ring 34 can block the gap between the rotating shaft 31 and the threaded sleeve 13, preventing food from entering the threaded sleeve 13. The gap between the sealing ring 34 and the threaded sleeve 13 is 0.2mm, so the threaded sleeve 13 will not cause wear to the sealing ring 34.

[0042] To cover the food, for example, such as Figure 5 As shown, a sealing gasket 12 is bonded and fixed to the outer wall of the material support plate 11, and the sealing gasket 12 is in contact with the inner wall of the storage box 1.

[0043] During use, the sealing gasket 12 ensures the sealing between the material support plate 11 and the storage box 1, and ensures the sealing of the internal storage environment of the storage box 1. When the material support plate 11 is removed from the storage box 1, the sealing gasket 12 can scrape and clean the residual material adhering to the inner wall of the storage box 1.

[0044] When this utility model is in use, the rotating handle 32 drives the threaded column 33 to rotate inside the threaded sleeve 13 according to the amount of food stored, so that the material support plate 11 rises or falls, adjusts the height of the storage space, and reduces air residue.

[0045] When replenishing a large amount of food, open the buckle 26, remove the cover plate 2, and place the food directly on the support plate 11. When replenishing a small amount of food, open the rubber plug 24 of the feed inlet 23 and pour the food in through the feed inlet 23.

[0046] When disassembling cover plate 2, first unlock buckle 26 and rotate handle 32 to disengage threaded post 33 from threaded sleeve 13, then cover plate 2 can be removed.

[0047] Connect the external nitrogen tank's pipeline to the quick connector 22, open the valve to inject nitrogen into the storage box 1, displacing the humid air. After the injection is complete, disconnect the connection. The quick connector 22's self-closing function blocks the gas supply pipe 21. The gas exchange inside the food can be optimized through the vent pipe 14 and the vent hole 15. The vent hole 15 adopts a through-hole design, and the size of the vent hole 15 is 0.3mm.
