[0002] Insulated containers are widely used in daily life. One type of insulated container, in addition to its conventional insulation function, also has a heat dissipation function. Specifically, to improve the speed of heat dissipation, this type of insulated container has vents at both the bottom and top of the outer shell. When heat dissipation is needed, the vents are opened to allow outside air to enter through the bottom vent and exit through the top vent, carrying away internal heat. A fan is also included to accelerate airflow.

[0003] Although the above-mentioned insulated container can achieve rapid heat dissipation, the space of the vacuum layer of the insulated container is compressed and the heat preservation area of ​​the vacuum layer is reduced by setting one of the vents on the upper part of the outer shell and configuring a drive component to open or close the upper vent. This results in a significant decrease in the heat preservation effect of the insulated container when it is in the heat preservation state. Utility Model Content

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

[0020] This invention provides a heat-insulating container with a rapid heat dissipation airflow, including a lid, an inner liner, an outer shell, a heat dissipation structure, a fan, and a damper assembly. The heat dissipation structure is fixedly connected to the inner liner; the fan is fixedly installed at the bottom of the inner liner, dividing the bottom space of the inner liner into an upper chamber and a lower chamber. Two sets of damper assemblies are configured, one set communicating with the upper chamber and the other with the lower chamber. Each damper assembly includes a ventilation hole and a damper. The ventilation hole connects the upper or lower chamber to the external environment, and the damper can selectively open or close the ventilation hole. Specifically, when rapid heat dissipation of the liquid inside the inner liner is required, the damper is opened to connect the ventilation hole with the upper and lower chambers, forming an airflow channel. The fan is turned on to accelerate airflow, allowing air to enter through the ventilation hole of one damper assembly, flow through the heat dissipation structure to carry away heat, and then exit through the ventilation hole of the other damper assembly after being accelerated by the fan. When heat preservation is required, the fan and damper assembly are turned off, and the ventilation hole is no longer connected to the upper and lower chambers, thus disconnecting the airflow channel. By incorporating ventilation holes and dampers, air ducts are formed between the ventilation holes and the upper and lower chambers. A fan accelerates airflow through these ducts, rapidly carrying away heat from the heat dissipation structure, thus quickly lowering the temperature of the liquid inside the inner liner. This method boasts high heat dissipation efficiency and a short cooling time. Furthermore, by placing both damper assemblies at the bottom of the inner liner, the insulation area of ​​the vacuum chamber is maximized, thereby ensuring the insulation effect of the insulated container.

[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] Example 1

[0046] like Figures 1 to 7 As shown in the figure, Embodiment 1 of this utility model provides a heat-insulating container with a rapid heat dissipation air duct, specifically including a lid 11, an inner liner 12, an outer shell 13, a heat dissipation structure, a fan 2, and a damper assembly 3. The inner liner 12 is used to store liquid, and the lid 11 is used to seal the inner liner 12. The lid 11 is threadedly connected to the outer shell 13 to facilitate opening or sealing the inner liner 12. A vacuum cavity is provided between the outer shell 13 and the inner liner 12.

[0047] Specifically, such as Figure 2 , Figure 5 and Figure 7 As shown, the heat dissipation structure is fixedly connected to the inner liner 12. The heat dissipation structure is made of thermally conductive material and can absorb the heat of the liquid inside the inner liner 12. The fan 2 is fixedly installed at the bottom of the inner liner 12, dividing the bottom space of the inner liner 12 into an upper chamber and a lower chamber. Two sets of damper assemblies 3 are configured. One set of damper assemblies 3 communicates with the upper chamber, and the other set communicates with the lower chamber. The damper assembly 3 includes a ventilation hole 31 and a damper 32. The ventilation hole 31 is used to connect the upper chamber or the lower chamber with the external environment, and the damper 32 can selectively open or close the ventilation hole 31. In detail, when it is necessary to quickly dissipate heat from the liquid inside the inner liner 12, the damper 32 is opened to connect the ventilation hole 31 with the upper and lower chambers to form an air duct. The fan 2 is turned on to accelerate the airflow, allowing air to enter through the ventilation hole 31 of one damper assembly 3, flow through the heat dissipation structure to carry away heat, and after being accelerated by the fan 2, flow out through the ventilation hole 31 of the other damper assembly 3. When heat preservation is required, fan 2 and damper assembly 3 are turned off, and ventilation hole 31 is not connected to the upper and lower chambers, thus disconnecting the air duct. By setting ventilation hole 31 and damper 32, an air duct is formed between ventilation hole 31 and the upper and lower chambers. Fan 2 accelerates airflow through the air duct and quickly removes heat from the heat dissipation structure, thereby rapidly reducing the liquid temperature inside the inner liner 12. Compared to existing heat preservation containers, this method has high heat dissipation efficiency and requires less heat dissipation time. By placing both damper assemblies 3 at the bottom of the inner liner, the installation space of the vacuum chamber is not compressed, thus ensuring the heat preservation area of ​​the vacuum chamber and consequently the heat preservation effect of the heat preservation container.

[0048] Specifically, in this embodiment, such as Figure 2 and Figure 3 As shown, the inner wall of the outer shell 13 and the outer wall of the inner liner 12 form a vacuum cavity, and the heat dissipation structure is fixedly connected to the bottom wall of the inner liner 12. Further, the heat dissipation structure includes a first heat dissipation plate 41 and a second heat dissipation plate 42 connected together. The first heat dissipation plate 41 is connected to the bottom wall of the inner liner 12, and multiple second heat dissipation plates 42 are arranged in parallel and spaced apart. More specifically, the first heat dissipation plate 41 is a circular plate, detachably connected to the inner liner 12. The multiple second heat dissipation plates 42 are all elongated plates, and each second heat dissipation plate 42 is perpendicular to the first heat dissipation plate 41. Two adjacent second heat dissipation plates 42 and the first heat dissipation plate 41 form a flow channel. Multiple flow channels are provided, and one end of each flow channel faces the damper assembly 3 located in the upper cavity. This arrangement allows the flow channel to guide air, enabling rapid air circulation to remove heat from the heat dissipation structure. Furthermore, the arrangement of the second heat dissipation plates 42 effectively increases the contact area between the air and the heat dissipation structure, thereby improving the heat dissipation effect.

[0049] Optionally, multiple second heat sinks 42 are arranged at an angle to the first heat sink 41. This arrangement, compared to a vertical arrangement of the second heat sinks 42, allows for a larger effective contact area with the air, thereby improving heat dissipation efficiency.

[0050] Preferably, such as Figure 1 and Figure 2 As shown, the insulated container also includes a base 8, which is detachably fixed to the outer shell 13. The base 8 and the inner liner 12 form a receiving cavity, and the fan 2 is disposed within the receiving cavity, dividing the receiving cavity into an upper cavity and a lower cavity. Two mounting holes are provided on the peripheral wall of the base 8, and two damper assemblies 3 are installed in the two mounting holes in a corresponding manner.

[0051] Specifically, such as Figure 4 As shown, the fan 2 includes a fan 2 body and a mounting plate 22. The mounting plate 22 is a circular plate and is fixedly installed in the accommodating cavity. A through hole is provided at the center of the mounting plate 22, and the fan 2 body is located at the through hole.

[0052] Preferably, such as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the damper assembly 3 also includes an air box 33 and a drive assembly 34. Specifically, the air box 33 is embedded in the mounting hole of the base 8. After the air box 33 is inserted into place, it is detachably fixed to the base 8 by fasteners. Ventilation holes 31 are opened on the outer wall of the air box 33, and multiple ventilation holes 31 are configured. After the air box 33 is fixed in place, the outer wall of the air box 33 is flush with the outer wall of the base 8, thereby improving the sealing between the damper assembly 3 and the base 8, ensuring the heat preservation effect of the heat preservation container, and making the heat preservation container more aesthetically pleasing. More specifically, the damper 32 is integrally equipped with a rotating shaft 321. The damper 32 is rotatably mounted in the air box 33 via the rotating shaft 321. The drive assembly 34 is fixedly mounted in the air box 33. The drive assembly 34 includes a drive motor 341, a worm gear 342, and a worm 343. The drive motor 341 is connected to the worm 343, the worm gear 342 is fixedly connected to one end of the rotating shaft 321, and the worm 343 meshes with the worm gear 342. By setting the drive motor 341 and the worm gear 342 and worm 343 transmission, the rotation of the damper 32 can be realized more conveniently. In addition, the worm gear 342 and worm 343 transmission has a self-locking characteristic, thereby ensuring that the damper 32 will not be rotated by other forces when it is closed or open, thus ensuring the heat preservation and heat dissipation effect of the insulation container.

[0053] As an alternative, the turbine and worm 343 can be replaced with two meshing bevel gears, one of which is fitted onto one end of the rotating shaft 321, and the other bevel gear is fixedly connected to the output end of the drive motor 341, which can also achieve the purpose of driving the damper 32 to rotate.

[0054] More specifically, such as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a partition 35 is provided inside the air box 33, dividing the internal space of the air box 33 into a ventilation chamber and a drive chamber. An air damper 32 is located in the ventilation chamber, and a ventilation hole 31 communicates with the ventilation chamber. A drive assembly 34 is located in the drive chamber. The partition 35 has a shaft hole, through which one end of a rotating shaft 321 extends into the drive chamber and is fixedly connected to a worm gear 342. A limit groove 3211 is provided on the portion of the rotating shaft 321 located in the drive chamber, and a limit block 351 engages with the limit groove 3211. Specifically, during operation, the drive motor 341 drives the worm gear 343 to rotate clockwise or counterclockwise. The worm gear 342 and the worm gear 343 drive the rotating shaft 321 fixedly connected to the worm gear 342 to rotate, thereby rotating the air damper 32 and switching between the closed and open states of the air damper 32. Preferably, the two ends of the extending direction of the limiting groove 3211 correspond to the closed state and the maximum opening state of the damper 32, respectively. The limiting groove 3211, in cooperation with the limiting block 351, restricts the rotation range of the damper 32, ensuring that no air infiltration occurs when the damper 32 is closed, thus guaranteeing the insulation effect of the insulation container. When the damper 32 is at its maximum opening, the resistance to air entry or exit is minimized, allowing the insulation container to dissipate heat with maximum efficiency. Specifically, in this embodiment, when the damper 32 is closed, it is perpendicular to the bottom wall of the base 8; when the damper 32 is at its maximum opening, it is parallel to the bottom wall of the base 8.

[0055] Preferably, in order to further ensure the insulation effect of the insulated container, such as... Figure 5 and Figure 6 As shown, the damper assembly 3 also includes a sealing ring 36, which surrounds the damper 32 and is fixedly connected to the inner wall of the ventilation cavity. This arrangement prevents air from seeping into the ventilation cavity through the gap between the damper 32 and the ventilation cavity when the damper 32 is closed, thus avoiding any impact on the insulation performance of the insulated container. Specifically, the sealing ring 36 can be made of flexible insulation materials such as rubber or foam, which further enhances the insulation effect of the insulated container.

[0056] Preferably, such as Figure 2 and Figure 3As shown, a semiconductor cooling chip 5 is sandwiched between the heat dissipation structure and the bottom wall of the inner liner 12. The semiconductor cooling chip 5 can help lower the temperature of the liquid inside the inner liner 12, and can lower the temperature inside the inner liner 12 to below the external ambient temperature. This configuration can improve the heat dissipation efficiency of the insulated container. In addition, the semiconductor cooling chip 5 also has a heating function. In cold winters, due to the low temperature of the external environment, the temperature of the liquid inside the inner liner 12 is often lower than the normal drinking temperature range. At this time, the semiconductor cooling chip 5 heats the liquid in the inner liner 12 to reach a suitable drinking temperature range. This configuration enriches the functions of the insulated container and improves the user experience.

[0057] Preferably, such as Figure 1 , Figure 2 and Figure 6 As shown, the insulated container also includes a controller 71, a display screen 72, a temperature sensor 73, and a switch button 74. The temperature sensor 73 is installed on the bottom wall of the inner liner 12. The thermoelectric cooler 5, fan 2, drive motor 341, temperature sensor 73, display screen 72, and switch button 74 are all electrically connected to the controller 71. Specifically, the controller 71 is located in the lower cavity of the base 8 and is a PCBA board. The display screen 72 and switch button 74 are installed on the peripheral wall of the base 8. The display screen 72 can be a touch screen. In detail, during operation, the heat dissipation function is activated by the switch button 74. The temperature sensor 73 can detect the temperature of the liquid inside the inner liner 12 in real time and transmit the temperature information to the controller 71. The controller 71 receives the temperature information and transmits it to the display screen 72, which displays the temperature of the liquid inside the inner liner 12 in real time. In addition, the touch screen can be used to control the thermoelectric cooler 5 to turn on, cool or heat, control the fan 2 to turn on or off, and control the working status of the drive motor 341. When the temperature of the liquid inside the inner liner 12 reaches the expected temperature, the heat dissipation function is deactivated by the switch button 74. This setup allows for real-time monitoring of the liquid temperature inside the inner liner 12, facilitating user control over the activation time of the heat dissipation function of the insulated container and making the container more intelligent.

[0058] Optionally, the insulated container also includes a battery and a charging connector connected to the battery. Both the battery and the charging connector are fixedly installed within the accommodating cavity. The battery is charged via the charging connector and provides power to components such as the controller 71 and the drive motor 341. This configuration improves the portability of the insulated container. Alternatively, in other embodiments, the controller 71 can be connected to an external power outlet via a wire.

[0059] It should be explained in detail that, in this embodiment, as Figure 2 , Figure 3 and Figure 7As shown, air enters the lower cavity through the ventilation hole 31 of the damper assembly 3, which is connected to the lower cavity. In the lower cavity, air can carry away some of the heat from the controller 71 and the battery, ensuring the working state of the controller 71 and the battery. Then, the air is drawn into the upper cavity by the fan 2. The fan 2 blows the air to the second heat sink 42 and the first heat sink 41. Most of the air moves along the flow channel to the ventilation hole 31 located in the upper cavity. In this process, the air carries away the heat from the second heat sink 42 and the first heat sink 41. Finally, the air flows out to the external environment through the ventilation hole 31 of the damper assembly 3 located in the upper cavity.

[0060] Example 2

[0061] To avoid redundancy, this embodiment only describes the features that differ from Embodiment 1. For example... Figures 8 to 10 As shown in the diagram, in this embodiment, an intermediate shell 14 is provided between the outer shell 13 and the inner liner 12. A vacuum cavity is provided between the intermediate shell 14 and the outer shell 13. The intermediate shell 14 has a receiving cavity, and the inner liner 12 is disposed in the receiving cavity. The heat dissipation structure is heat dissipation fins 43, which extend along the height direction of the inner liner 12. Multiple heat dissipation fins 43 are arranged, and the multiple heat dissipation fins 43 are distributed at intervals along the circumference of the inner liner 12. Specifically, the upper cavity is connected to the receiving cavity.

[0062] Preferably, a baffle plate 6 is installed on the peripheral wall of the inner liner 12. The baffle plate 6 is used to separate the damper assembly 3 disposed in the upper cavity from the air outlet of the fan 2. Specifically, as shown in the figure... Figures 8 to 10 As shown, the baffle 6 includes an arc-shaped plate 61 and two strip plates 62 connected to both ends of the arc-shaped plate 61. The upper end of the arc-shaped plate 61 is fixedly connected to the bottom wall of the inner liner 12, and the lower end is fixedly connected to the mounting plate 22 of the fan 2. The two strip plates 62 extend vertically upward and are spaced apart from the inner top wall of the intermediate shell 14. The two ends of the strip plates 62 in the width direction are respectively connected to the outer peripheral wall of the inner liner 12 and the inner peripheral wall of the intermediate shell 14. With this configuration, due to the blocking effect of the baffle 6, after the air enters the upper cavity from the lower cavity, the air can only move upward in the vertical direction and contact a portion of the heat dissipation fins 43 to remove its heat. Then, at the top of the cavity where there is no baffle 6, the air changes direction and moves downward in the vertical direction to contact another portion of the heat dissipation fins 43 to remove its heat, and finally flows out to the external environment through the ventilation hole 31 located in the upper cavity. This configuration ensures that the air can fully contact the heat dissipation fins 43, thereby ensuring the heat dissipation efficiency of the insulation container.
