Insulated container

Abstract

This utility model discloses a heat-insulating cylinder, including a cylinder cover, an outer cylinder shell, an aluminum cylinder, a heat-insulating sleeve, and a refrigeration component. The lower part of the outer cylinder shell is provided with multiple air outlets arranged in a ring. The aluminum cylinder is installed inside the outer cylinder shell. The heat-insulating sleeve is fitted onto the aluminum cylinder and is located between the aluminum cylinder and the inner wall of the outer cylinder shell. The refrigeration component is installed inside the outer cylinder shell and contacts the bottom of the aluminum cylinder. The refrigeration component provides a cooling effect to the interior of the aluminum cylinder, ensuring that the interior of the aluminum cylinder maintains a low-temperature environment. During the cooling process, the refrigeration component generates a large amount of heat.

This prevents heat accumulation inside the outer shell from affecting the cooling effect of the refrigeration component and ensures that the service life of the refrigeration component is not affected by prolonged exposure to high temperatures.

Description

Technical Field

[0001] This utility model relates to the field of thermal insulation materials, and in particular to a thermal insulation cylinder. Background Technology

[0002] When people go out, they often need to carry a lot of food, including but not limited to beverages, water, milk, coffee, tea, etc. Some foods need to be stored at low temperatures. In hot environments, drinking water can be cooled down before drinking. When taking infants out, breast milk also needs to be stored at low temperatures to prevent it from spoiling very easily at room temperature.

[0003] To meet these needs, people carry cryogenic storage items such as thermos cups and bottles when they go out. However, existing insulation equipment is susceptible to temperature fluctuations due to external environmental factors, which can affect the preservation effect. In addition, the refrigeration devices of existing cryogenic storage items generate a lot of heat during use, so it is necessary to remove the generated heat from the cryogenic storage items in a timely manner to prevent this heat from interfering with the temperature inside the cryogenic storage items.

The heat-insulating sleeve isolates the aluminum cylinder from heat exchange with the external space, enabling the aluminum cylinder to maintain a stable low-temperature environment, avoiding the influence of external ambient temperature, and improving the preservation effect.

[0005] According to some embodiments of the present invention, the outer shell includes a first shell and a second shell, the second shell is installed at the bottom of the first shell, a cap is installed at the top opening of the first shell, and the aluminum cylinder is located inside the first shell. According to some embodiments of this utility model, in order to ensure a stable connection between the first cylindrical shell and the second cylindrical shell, an mounting ring groove is provided at the top opening of the second cylindrical shell. The bottom edge of the first cylindrical shell is inserted into the mounting ring groove, and the first cylindrical shell and the second cylindrical shell can be further connected by screws.

[0006] According to some embodiments of the present invention, a support frame is installed at the top opening of the second cylinder shell. The support frame includes a chassis and a frame disposed on the top surface of the chassis. The edge of the chassis is connected to the mounting ring groove. The bottom of the aluminum cylinder is supported on the frame to support the aluminum cylinder and ensure the stability of the aluminum cylinder after assembly.

[0007] According to some embodiments of this utility model, a cold storage block is installed inside the frame, with the top surface of the cold storage block in contact with the bottom of the aluminum cylinder and the bottom surface of the cold storage block in contact with the refrigeration component, so that the cold energy generated by the refrigeration component is stored by the cold storage block.

[0008] According to some embodiments of this utility model, a mounting base is installed at the top opening of the first cylindrical shell. The mounting base can be detachably mounted on the cylindrical cover. At the same time, the mounting base can press the aluminum cylinder onto the frame to ensure the stability of the aluminum cylinder after installation.

[0009] According to some embodiments of this utility model, the mounting base is provided with a first contact surface, and the first contact surface is provided with an internal thread. The cylinder cover is provided with an external thread, which is used to engage with the internal thread to achieve a stable connection between the cylinder cover and the mounting base.

[0010] According to some embodiments of this utility model, a first sealing ring is fitted onto the cylinder cover, and after the cylinder cover is installed, the first sealing ring is tightly attached to the first contact surface.

[0011] According to some embodiments of this utility model, a second contact surface is also provided on the mounting base, and a second sealing ring is fitted on the mounting base. The bottom of the second sealing ring contacts the second contact surface. After the cylinder cover is installed, the top of the second sealing ring contacts the edge of the cylinder cover opening, so that the first sealing ring and the second sealing ring cooperate with each other to achieve double sealing and further enhance the sealing.

[0012] According to some embodiments of this utility model, to prevent cold air from diffusing outward from the cap, aluminum foil is adhered and fixed to the bottom of the inner cavity of the cap. The aluminum foil has good reflectivity and can reflect some heat. Simultaneously, polyurethane foam blocks are also filled inside the cap, positioned above the aluminum foil. According to some embodiments of the present invention, an air outlet grille is provided on the shell wall of the second shell, and multiple air inlets are also provided at the bottom of the second shell. External cold air enters the second shell through the air inlets, exchanges heat with the refrigeration components, and is discharged from the air outlet grille.

[0013] According to some embodiments of the present invention, the cooling component includes a semiconductor cooling chip, a heat sink, and a cooling fan. The semiconductor cooling chip is in contact with the bottom of the cold storage block, the heat sink is in close contact with the bottom of the semiconductor cooling chip, and the cooling fan is fixed to the bottom of the second cylindrical shell. The cooling fan is located below the heat sink and above the air inlet.

[0014] According to some embodiments of the present invention, the insulation sleeve includes, from the inside out, an aerogel felt layer, an aluminum foil layer, and a polyurethane foam layer. The aerogel felt layer wraps around the aluminum cylinder, and the aluminum foil layer is sandwiched between the aerogel felt layer and the polyurethane foam layer.

[0015] According to some embodiments of this utility model, the space between the aluminum cylinder and the inner wall of the first cylinder shell is relatively small, and the aerogel felt, while having the same heat insulation effect as other heat insulation materials, is much thinner than other heat insulation materials, so that while taking into account space utilization and reducing thickness, a good heat insulation effect can be guaranteed.

[0016] This utility model has at least the following beneficial effects: 1. The cooling component is installed inside the outer shell and contacts the bottom of the aluminum cylinder. The cooling component provides a cooling effect to the inside of the aluminum cylinder, ensuring that the inside of the aluminum cylinder maintains a low temperature environment. During the cooling process, the cooling component generates a lot of heat. To improve the heat dissipation effect, the cooling component is surrounded by an air outlet, so that the heat inside the outer shell can be quickly dissipated to the external environment, avoiding the accumulation of heat inside the outer shell that affects the cooling effect of the cooling component, and ensuring that the service life of the cooling component is not affected by long-term exposure to high temperature environments.

[0017] 2. During refrigeration, the cold storage block absorbs and stores cold energy, thereby creating a stable low-temperature environment inside the aluminum cylinder. At the same time, when the refrigeration components are not working, the cold storage block slowly releases cold energy, extending the cooling time of the aluminum cylinder.

[0018] 3. Because the polyurethane foam blocks completely fill the inner cavity of the cylinder cover, there are no gaps in the inner cavity of the cylinder cover. In addition, the polyurethane foam blocks have excellent thermal insulation properties. Through the cooperation between the polyurethane foam blocks and the aluminum foil paper, they jointly isolate the external heat entering through the cylinder cover, ensuring that the low temperature environment inside the aluminum cylinder remains stable.

[0019] 4. Furthermore, the aluminum foil layer reflects heat, and the polyurethane foam layer fills the gap between the aluminum cylinder and the inner wall of the first cylinder shell to achieve the best heat preservation and insulation effect.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0024] Reference Figures 1 to 4 The insulation cylinder includes a cylinder cover 100, an outer cylinder shell 200, an aluminum cylinder 300, a heat insulation sleeve 400, and a refrigeration component 500. The cylinder cover 100 is detachably installed at the top opening of the outer cylinder shell 200, and multiple air outlets 201 are provided at the lower part of the outer cylinder shell 200, which are arranged in a ring. The aluminum cylinder 300 is installed inside the outer cylinder shell 200. The heat insulation sleeve 400 is fitted onto the aluminum cylinder 300, and the heat insulation sleeve 400 is located between the aluminum cylinder 300 and the inner wall of the outer cylinder shell 200. The heat insulation sleeve 400 isolates the aluminum cylinder 300 from the external space, so that the aluminum cylinder 300 can maintain a stable low temperature environment, avoid the influence of the external ambient temperature, and improve the preservation effect.

[0025] The cooling component 500 is installed inside the outer shell 200 and is in contact with the bottom of the aluminum cylinder 300. The cooling component 500 provides a cooling effect to the inside of the aluminum cylinder 300, ensuring that the inside of the aluminum cylinder 300 maintains a low temperature environment. During the cooling process, the cooling component 500 generates a large amount of heat. To improve the heat dissipation effect, the cooling component 500 is surrounded by the air outlet 201, so that the heat inside the outer shell 200 can be quickly dissipated to the external environment, avoiding the accumulation of heat inside the outer shell and affecting the cooling effect of the cooling component 500. This ensures that the service life of the cooling component 500 will not be affected by long-term exposure to high temperature environments.

[0026] Reference Figure 4 The outer shell 200 includes a first shell 210 and a second shell 220. The second shell 220 is installed at the bottom of the first shell 210. A cap 100 is installed at the top opening of the first shell 210. The aluminum cylinder 300 is located inside the first shell 210. To ensure a stable connection between the first cylindrical shell 210 and the second cylindrical shell 220, an mounting annular groove 221 is provided at the top opening of the second cylindrical shell 220. The bottom edge of the first cylindrical shell 210 is inserted into the mounting annular groove 221, and the first cylindrical shell 210 and the second cylindrical shell 220 can be further connected by screws.

[0027] Reference Figure 4 , 6 7 to 9, a support frame 230 is installed at the top opening of the second cylindrical shell 220. The support frame 230 includes a chassis 231 and a frame 232 set on the top surface of the chassis 231. The edge of the chassis 231 is connected to the mounting ring groove 221. The frame 232 supports the bottom of the aluminum cylinder 300 to support the aluminum cylinder 300 and ensure the stability of the aluminum cylinder 300 after assembly.

[0028] Meanwhile, a cold storage block 600 is installed inside the frame 232. The top surface of the cold storage block 600 is in contact with the bottom of the aluminum cylinder 300, and the bottom surface of the cold storage block 600 is in contact with the refrigeration component 500, so that the cold energy generated by the refrigeration component 500 is stored by the cold storage block 600.

[0029] During refrigeration, the cold storage block 600 absorbs and stores cold energy, thereby creating a stable low-temperature environment inside the aluminum cylinder 300. At the same time, when the refrigeration component 500 is not working, the cold storage block 600 slowly releases cold energy, extending the cold retention time of the aluminum cylinder 300.

[0030] Reference Figure 4 , 5 A mounting base 240 is installed at the top opening of the first cylindrical shell 210. The mounting base 240 can be detachably mounted on the cylindrical cover 100. At the same time, the mounting base 240 can press the aluminum cylinder 300 onto the frame 232 to ensure the stability of the aluminum cylinder 300 after installation.

[0031] The mounting base 240 is provided with a first contact surface 241, and the first contact surface 241 is provided with an internal thread. The cylinder cover 100 is provided with an external thread, which is used to engage with the internal thread to achieve a stable connection between the cylinder cover 100 and the mounting base 240.

[0032] Reference Figure 5 As shown, in order to further improve the sealing of the inner cavity of the aluminum cylinder 300 and avoid the loss of cold energy, a first sealing ring 700 is fitted on the cylinder cover 100. After the cylinder cover 100 is installed, the first sealing ring 700 is tightly attached to the first contact surface 241.

[0033] Meanwhile, a second contact surface 242 is also provided on the mounting base 240, and a second sealing ring 800 is fitted on the mounting base 240. The bottom of the second sealing ring 800 contacts the second contact surface 242. After the cylinder cover 100 is installed, the top of the second sealing ring 800 contacts the edge of the cover opening of the cylinder cover 100, so that the first sealing ring 700 and the second sealing ring 800 cooperate with each other to achieve double sealing and further enhance the sealing.

[0034] To prevent cold energy from diffusing outward from the cover 100, a cover cavity 101 is provided in the cover 100. An aluminum foil 110 is attached and fixed to the bottom of the cover cavity 101. The aluminum foil 110 has good reflectivity and can reflect some heat. At the same time, a polyurethane foam block 120 is also filled in the inner cavity of the cover 100, and the polyurethane foam block 120 is located above the aluminum foil 110.

[0035] Since the polyurethane foam block 120 fills the inner cavity of the cylinder cover 100 completely, there are no gaps in the inner cavity of the cylinder cover 100. In addition, the polyurethane foam block 120 has excellent thermal insulation performance. Through the cooperation between the polyurethane foam block 120 and the aluminum foil 110, they jointly insulate the external heat and ensure that the low temperature environment inside the aluminum cylinder 300 remains stable.

[0036] Reference Figure 9 As shown, specifically, an air outlet 201 is provided on the shell wall of the second shell 220, and multiple air inlets 202 are also provided at the bottom of the second shell 220. External cold air enters the second shell 220 through the air inlets 202, exchanges heat with the refrigeration component 500, and is discharged from the air outlet 201.

[0037] Specifically, the cooling component 500 includes a thermoelectric cooler 510, a heat sink 520, and a cooling fan 530. The thermoelectric cooler 510 is in contact with the bottom of the cold storage block 600, the heat sink 520 is in close contact with the bottom of the thermoelectric cooler 510, and the cooling fan 530 is fixed to the bottom of the second cylindrical shell 220. The cooling fan 530 is located below the heat sink 520 and above the air inlet 202.

[0038] Reference Figure 2 , 4 As shown, when the semiconductor cooling chip 510 starts working, its cold end contacts the cold storage block 600 or the aluminum cylinder 300, and its hot end contacts the heat sink 520. Heat is transferred to the heat sink 520, and the cooling fan 530 blows the cold air that enters through the air inlet 202 toward the heat sink 520. After the cold air completes the heat exchange at the heat sink 520, it is discharged through the air outlet 201 to complete the heat dissipation process. Since the heat sink 520 is surrounded by the air outlet 201, the hot air generated after the heat exchange is completed can be quickly discharged outward from the second shell 220, improving the heat dissipation efficiency.

[0039] Reference Figure 5 As shown, the insulation jacket 400 includes, from the inside out, an aerogel felt layer 410, an aluminum foil layer 420, and a polyurethane foam layer 430. The aerogel felt layer 410 wraps around the aluminum cylinder 300, the aluminum foil layer 420 is sandwiched between the aerogel felt layer 410 and the polyurethane foam layer 430, and the polyurethane foam layer 430 is filled between the aerogel felt layer 410 and the first cylinder shell 210, as well as between the bottom of the aluminum cylinder 300 and the chassis 231, thus achieving full-enclosure insulation of the aluminum cylinder 300.

[0040] To ensure product portability, the product's size is limited. Therefore, the space between the aluminum cylinder 300 and the inner wall of the first cylinder shell 210 is small. While the aerogel felt has the same thermal insulation effect as other insulation materials, its thickness is much thinner. This allows for good thermal insulation while balancing space utilization and reducing thickness.

[0041] Furthermore, the aluminum foil layer 420 reflects heat due to its reflectivity, while the polyurethane foam layer 430 fills the gap between the aluminum cylinder 300 and the inner wall of the first cylinder shell 210, thus achieving the best heat preservation and insulation effect.
