Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, and more specifically, to a vacuum-sealed storage and preservation device for rice. Background Technology

[0002] Rice is a grain obtained by processing paddy rice through hulling, milling, and other processes. It is one of the most important staple foods in the world. Currently, rice is easily affected by moisture, oxidation, and pests during storage, leading to nutrient loss and a deterioration in taste. Therefore, vacuum sealing devices are needed to remove air from the device, reduce the presence of oxygen and moisture, thereby inhibiting the growth of microorganisms and chemical reactions, delaying the deterioration of rice. In addition, vacuum sealing devices can also prevent pests from entering, ensuring that rice can remain fresh and nutritious even after long-term storage.

[0003] Current vacuum sealing devices first use a vacuum pump to extract air from the packaging, reducing oxygen content and inhibiting microbial growth and oxidation. Then, the sealing equipment ensures the packaging is completely sealed, usually through a sealing gasket. However, with prolonged use, taking a vacuum-sealed box as an example, the sealing gasket gradually loosens due to repeated opening and closing of the lid, further deteriorating the sealing effect. This requires operators to adjust or replace the gasket during use, making it difficult to achieve a stable seal and increasing the risk of rice becoming damp and oxidized. Therefore, improvements and optimizations are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a vacuum sealing storage and preservation device for rice, which has the advantages of high sealing effect and high sealing stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum-sealed storage and preservation device for rice, comprising a preservation box, a sealing cover, and a hinge. The top of the preservation box is provided with a sealing cover, and the preservation box and the sealing cover are rotatably connected by a hinge. A sealing groove is provided on the top of the inner wall of the preservation box, and a raised edge is provided on the bottom of the sealing cover. A sealing airbag is provided inside the raised edge, and a vacuum extraction port is provided on the top of the sealing cover.

[0006] The sealing cover has an inflatable chamber inside, a piston plate is movably installed inside the inflatable chamber, and a reciprocating screw is rotatably installed inside the inflatable chamber. The piston plate and the reciprocating screw are threaded together. A knob is rotatably installed on the top of the sealing cover.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, this utility model provides a vacuum-sealed storage and preservation device for rice, including a preservation box 1, a sealing cover 2 and a hinge 3. The top of the preservation box 1 is provided with the sealing cover 2, and the preservation box 1 and the sealing cover 2 are rotatably connected by the hinge 3. The top of the inner wall of the preservation box 1 is provided with a sealing groove 4, the bottom of the sealing cover 2 is provided with a raised edge 5, the inside of the raised edge 5 is provided with a sealing airbag 6, and the top of the sealing cover 2 is provided with a vacuum extraction port 31.

[0028] An air chamber 7 is provided inside the sealing cover 2. A piston plate 8 is movably installed inside the air chamber 7. A reciprocating screw 9 is rotatably installed inside the air chamber 7. The piston plate 8 and the reciprocating screw 9 are threaded together. A knob 10 is rotatably installed on the top of the sealing cover 2. The top of the reciprocating screw 9 passes through the sealing cover 2 and is fixedly connected to the knob 10. An air inlet 11 is provided on the top of the sealing cover 2. The air inlet 11 is connected to the air chamber 7. An air inlet 15 is provided at the bottom of the air chamber 7. The bottom of the air inlet 15 is connected to the sealing airbag 6.

[0029] When rice needs to be stored fresh, the staff first puts the rice into the inside of the preservation box 1, then closes the sealing lid 2. The staff then rotates knob 10, which drives the reciprocating screw 9 to rotate. The rotation of the reciprocating screw 9 causes the piston plate 8, which is threaded onto it, to move downwards. However, the inside of the inflation chamber 7 is sealed. When the piston plate 8 moves downwards, it pushes air downwards, further pushing the plug 16 downwards and opening the inflation port 15. At this time, air enters the sealed airbag 6 through the inflation port 15, causing the sealed airbag 6 to inflate. The expansion of the sealed airbag 6 causes it to abut against the sealing groove 4, filling and sealing the gap between the preservation box 1 and the sealing lid 2. Then, the staff extracts the air from the inside of the preservation box 1 through the vacuum extraction port 31, making the inside of the preservation box 1 a vacuum state to ensure the freshness of the rice. The staff can rotate the knob 10 multiple times to make the piston plate 8 move up and down inside the inflation chamber 7. When the piston plate 8 moves downward, air will enter the inside of the sealing airbag 6 through the inflation port 15. When the piston plate 8 moves upward, the plug 16 will be reset by the elastic potential energy of the spring 17, sealing the inflation port 15 again to prevent air leakage. The upward movement of the piston plate 8 will also draw outside air into the inside of the inflation chamber 7 through the air inlet 11. The staff can control the up and down movement of the piston plate 8 to control the expansion range of the sealing airbag 6 to ensure a firm and stable seal.

[0030] Rotating the knob 10 causes the piston plate 8 to move up and down. When the piston plate 8 moves downward, the air inside the inflation chamber 7 enters the sealing airbag 6 through the inflation port 15. When the piston plate 8 moves upward, the air inlet 11 replenishes the air inside the inflation chamber 7. Compared with traditional devices, this device ensures a stable seal between the preservation box 1 and the sealing cover 2 through the setting of the sealing airbag 6, and can adapt to different sealing requirements. More importantly, the inflated airbag can fit tightly against the sealing surface, forming a uniform pressure distribution and improving the sealing performance.

[0031] Among them, the right side of the sealing cover 2 is provided with a slot 21, and the top right side of the preservation box 1 is fixedly installed with a block 22, and the slot 21 and the block 22 are in corresponding positions.

[0032] The slot 21 has a telescopic groove 23 inside, and a wedge 24 is movably installed inside the telescopic groove 23. The wedge 24 and the telescopic groove 23 are elastically connected by a spring 3 25. The block 22 has a fixing groove 26 inside, and the wedge 24 abuts against the fixing groove 26 through the elastic potential energy of the spring 3 25.

[0033] When the sealing cover 2 is closed, the slot 21 and the block 22 engage with each other. When the sealing cover 2 is closed, the wedge 24 is squeezed into the telescopic groove 23 by the block 22. When the sealing cover 2 is fully closed, the wedge 24 will be reset outward by the elastic potential energy of the spring 3 25. At this time, the wedge 24 enters the fixed groove 26, thus completing the fixation of the sealing cover 2.

[0034] By pressing the sealing cap 2 downwards, the wedge 24 is squeezed into the telescopic groove 23. When the sealing cap 2 is on top of the refrigerator 1, the wedge 24 abuts against the fixing groove 26, thus fixing the sealing cap 2. Compared with traditional devices, this device can quickly close the sealing cap 2. When it is necessary to take out the rice, the wedge 24 is retracted into the telescopic groove 23 by pressing the button 30. Then, the staff can open the sealing cap 2, which effectively improves the efficiency of opening and closing and reduces the workload.

[0035] The air inlet 11 is fixedly installed with a fixing post 13. A plug 12 is movably sleeved on the top of the fixing post 13. The plug 12 and the fixing post 13 are elastically connected by a spring 14. The plug 12 seals the top of the air inlet 11.

[0036] The design of the air inlet 11 ensures that only outside air is allowed to enter the interior of the inflation chamber 7.

[0037] The inflation port 15 has a fixed post 18 inside, and a plug 16 is movably sleeved on the top of the fixed post 18. The plug 16 and the fixed post 18 are elastically connected by a spring 17, and the plug 16 seals the top of the inflation port 15.

[0038] The design of the inflation port 15 allows only the air inside the inflation chamber 7 to enter the sealed airbag 6 through the inflation port 15.

[0039] The protruding edge 5 and the sealing groove 4 are positioned corresponding to each other, and the sealing airbag 6 will enter the interior of the sealing groove 4 after expansion and abut against the inner wall of the sealing groove 4.

[0040] The expansion of the sealing airbag 6 ensures a firm and stable seal between the food storage box 1 and the sealing lid 2.

[0041] The outer wall of the food storage box 1 has an observation window 19, and the right side of the observation window 19 has a scale 20.

[0042] Staff can determine the amount of rice inside the preservation box 1 by observing window 19 and scale 20.

[0043] The outer wall of the fixing groove 26 is fixedly installed with a fixing cylinder 27, and a ejector pin 28 is movably installed inside the fixing cylinder 27. The left end of the ejector pin 28 extends through the fixing groove 26.

[0044] The ejector pin 28 and the outer wall of the fixing groove 26 are elastically connected by a spring 29. A button 30 is fixedly installed on the right end of the ejector pin 28, and the button 30 is located on the right side of the fixing cylinder 27.

[0045] When it is necessary to remove the rice, the staff introduces air into the inside of the preservation box 1 through the vacuum extraction port 31, and then presses the button 30. Pressing the button 30 will push the ejector pin 28 along the fixed cylinder 27. Further, the ejector pin 28 pushes the spring 3 25 into the inside of the telescopic groove 23. At this time, the staff can open the sealing cover 2.

[0046] Working principle and usage process of this utility model:

[0047] When rice needs to be stored fresh, the staff can first put the rice into the inside of the preservation box 1, and then close the sealing cover 2. When the sealing cover 2 is closed, the slot 21 and the block 22 engage with each other, and the wedge 24 is pressed into the telescopic groove 23 by the block 22. When the sealing cover 2 is fully closed, the wedge 24 will be reset outward by the elastic potential energy of the spring 3 25, and at this time the wedge 24 enters the fixed groove 26, completing the fixation of the sealing cover 2. Then the staff can rotate the knob 10 to rotate... The rotation of button 10 drives the reciprocating screw 9 to rotate. The rotation of the reciprocating screw 9 causes the piston plate 8, which is threadedly connected to it, to move downward. However, the inside of the inflation chamber 7 is sealed. When the piston plate 8 moves downward, it pushes the air downward, further pushing the plug 16 downward and opening the inflation port 15. At this time, air enters the interior of the sealing airbag 6 through the inflation port 15, causing the sealing airbag 6 to inflate. The expansion of the sealing airbag 6 causes it to abut against the sealing groove 4, filling the gap between the food storage box 1 and the sealing cover 2. After filling and sealing, the staff extracts the air from the inside of the preservation box 1 through the vacuum extraction port 31, creating a vacuum inside the preservation box 1 to ensure the freshness of the rice. The staff can rotate the knob 10 multiple times to move the piston plate 8 up and down inside the air filling chamber 7. When the piston plate 8 moves downward, air enters the sealing air bag 6 through the air filling port 15. When the piston plate 8 moves upward, the plug 16 will reset due to the elastic potential energy of the spring 17, resealing the air filling port 15 to prevent air leakage. The upward movement of the piston plate 8... The system draws outside air into the inflation chamber 7 through the air inlet 11. The operator can control the up and down movement of the piston plate 8 to control the expansion of the sealing airbag 6, ensuring a firm and stable seal. When the rice needs to be removed, the operator introduces air into the refrigerator 1 through the vacuum extraction port 31, and then presses the button 30. Pressing the button 30 will push the ejector pin 28 along the fixed cylinder 27. Further, the ejector pin 28 pushes the spring 3 25 into the telescopic groove 23, at which point the operator can open the sealing cover 2.
