Description

Technical Field

[0001] This invention relates to the field of container lid technology, specifically to a steplessly adjustable manual heat dissipation container lid. Background Technology

[0002] Container lids are common components used to seal container openings. Their main functions include protecting the contents from external environmental contamination, preventing accidental spillage during movement or pouring, and maintaining heat or cold within the container to a certain extent. In applications requiring lowering the temperature of the contents, such as when holding hot drinks, hot soup, or chemical reagents that need rapid cooling, users typically desire containers with active heat dissipation capabilities to shorten waiting times.

[0003] Currently, common designs for traditional container lids to achieve heat dissipation include vents that can be opened and closed, independent cooling fans, or fully detachable lid structures. For example, some thermos lids have push-button or rotary spout switches that provide a seal when closed and allow for some ventilation when open; other lids are designed with a fully threaded structure, requiring the user to unscrew the entire lid to expose the container opening to the environment for rapid heat dissipation. These existing technologies alleviate the problem of excessively high contents temperatures to some extent.

[0004] However, the aforementioned existing technology still has the following drawbacks: In order to start or accelerate the heat dissipation process, the user must fully open the container lid, or at least open it to a large, fixed opening. This "open-lid" heat dissipation method allows the inside of the container to be directly and extensively connected to the external environment, making it easy for dust, microorganisms, or other impurities in the environment to fall into the container and contaminate the contents. At the same time, when the container tilts or is accidentally touched during the heat dissipation process, there is a risk that the internal liquid or solid contents may spill or splash from the large opening, causing not only waste but also potential safety issues such as burns or environmental pollution. Summary of the Invention

[0005] The purpose of this invention is to provide a steplessly adjustable manual heat dissipation container lid to solve the problem in the prior art where the container lid needs to be opened during heat dissipation, which leads to the easy entry of external impurities and the easy spillage of contents.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solution: a steplessly adjustable manual heat dissipation container cover, including a base for connecting with a container, a heat-conducting component for thermal contact with the inside of the container is disposed through the base, and the top end of the heat-conducting component is located above the base. The top of the base is provided with a movable cover that can cover the heat-conducting component, and an adjustment component is installed between the movable cover and the heat-conducting component. The adjustment component is used to control the movable cover to slide up and down along the outer side wall of the heat-conducting component, thereby controlling the contact area between the heat-conducting component and the external environment.

[0007] The base includes a first annular cover with a through hole, a first cavity, and a first insulation layer. The through hole is disposed through the top of the first annular cover, the heat-conducting component is disposed through the through hole, and the heat-conducting component is fixedly connected to the inner wall of the through hole. The first cavity is disposed inside the first annular cover, and the first insulation layer is filled inside the first cavity.

[0008] The heat-conducting component includes a heat-conducting outer cover, strip-shaped channels, and a heat-conducting inner cover. The heat-conducting outer cover is disposed through the base, and the heat-conducting inner cover is slidably inserted into the heat-conducting outer cover. The heat-conducting inner cover and the heat-conducting outer cover are interference-fitted. Several strip-shaped channels are distributed circumferentially along the side wall of the heat-conducting outer cover located above the base.

[0009] The movable cover includes a second annular cover, a second cavity, and a second insulation layer. The second annular cover is slidably sleeved with a heat-conducting component, the second cavity is disposed inside the second annular cover, and the second insulation layer is filled and disposed inside the second cavity.

[0010] The adjustment assembly includes a screw and an internally threaded cylinder. The internally threaded cylinder passes through the top center of the heat-conducting outer cover and is fixedly connected to the heat-conducting outer cover. The screw is installed at the center of the upper surface inside the movable cover and is threadedly connected to the internally threaded cylinder.

[0011] An annular hole is opened at the top center of the heat-conducting inner cover for the internal threaded cylinder to pass through, and an annular piston is fixedly installed in the annular hole. The heat-conducting inner cover is slidably sleeved with the internal threaded cylinder through the annular piston.

[0012] The internally threaded cylinder passes through the top of the heat-conducting inner cover, and the bottom end of the internally threaded cylinder is located inside the heat-conducting outer cover. A stop is installed at the bottom end of the internally threaded cylinder to prevent the heat-conducting inner cover from separating from the internally threaded cylinder.

[0013] A sealing gasket is provided inside the first annular cover, and the sealing gasket is fitted onto the outer wall of the heat-conducting component near the bottom.

[0014] When the movable cover completely covers the heat-conducting component, the distance between the bottom end and the top end of the heat-conducting component is less than the length of the screw.

[0015] A rubber ring is provided on the inner wall of the heat-conducting inner cover near the bottom end, and an annular notch is opened along the bottom edge of the heat-conducting outer cover, and a matching sealing ring is installed at the annular notch.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. This invention utilizes a heat-conducting component that penetrates the base, allowing it to come into thermal contact with the container's interior and transfer heat from the container's interior to the exterior of the lid. Simultaneously, a movable lid is positioned on top of the base to cover the heat-conducting component, with an adjustment mechanism installed between the lid and the component. The user can manually operate the adjustment mechanism to control the movable lid's sliding and raising / lowering along the outer wall of the heat-conducting component, thus steplessly adjusting the area of ​​the component exposed to the external environment. When the lid completely covers the component, it isolates it from the outside environment, achieving heat preservation. As the lid gradually rises, the exposed area of ​​the component gradually increases, and the heat dissipation rate continuously increases. Throughout the heat dissipation process, the lid remains sealed to the container, eliminating the need to open the lid or expose the container opening. This effectively prevents external dust, microorganisms, and other impurities from entering the container, while also preventing spillage or splashing of contents when the container is tilted or bumped, significantly improving safety.

[0017] 2. This invention uses a heat-conducting component as a fixed channel for heat transfer from the inside of the container to the outside, and utilizes an adjusting component to drive the movable lid to move up and down continuously relative to the heat-conducting component, thereby controlling the heat exchange area between the heat-conducting component and the outside air in a continuously varying manner. This structure breaks away from the conventional thinking that container lids must be completely removed or opened significantly to accelerate heat dissipation, achieving free adjustment of the heat dissipation rate while the lid is always in a closed installation state. It fundamentally solves the two major technical problems of impurity intrusion and content leakage caused by opening the lid for heat dissipation. It has the functions of heat preservation, dust prevention, spill prevention, and stepless heat dissipation, and its structure is compact and easy to operate. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1 Traditional container lids, when needed to accelerate heat dissipation, typically require the lid to be fully opened, or at least opened to a large, fixed opening, creating direct, large-area communication between the container's interior and the external environment. While this method accelerates heat dissipation, it allows dust, microorganisms, or other impurities from the environment to easily fall into the container, contaminating the contents. Furthermore, if the container tilts or is accidentally touched during heat dissipation, the internal liquid or solid contents can easily spill or splash from the large opening, posing safety risks.

[0022] like Figure 1 This embodiment provides a steplessly adjustable manual heat dissipation container cover, including a base 100 for connecting to a container. A heat-conducting element 200 for thermal contact with the inside of the container is disposed through the base 100, and the top of the heat-conducting element 200 is located above the base 100. The top of the base 100 is provided with a movable cover 300 that can cover the heat-conducting element 200, and an adjustment component 400 is installed between the movable cover 300 and the heat-conducting element 200. The adjustment component 400 is used to control the movable cover 300 to slide up and down along the outer side wall of the heat-conducting element 200, thereby controlling the contact area between the heat-conducting element 200 and the external environment.

[0023] The working principle of the heat sink cover: Figure 1 As shown, the user manually operates the adjustment component 400, which drives the movable cover 300 to slide up and down relative to the heat-conducting component 200 along its outer side wall. When the movable cover 300 completely covers the heat-conducting component 200, the side wall area of ​​the heat-conducting component 200 exposed to the external environment is minimized, the heat conducted from the inside of the container to its upper part is difficult to dissipate to the environment, the heat dissipation rate is the lowest, and the container is in a heat preservation state. like Figure 2 As shown, when the user drives the movable cover 300 to gradually rise through the adjustment component 400, the side wall of the heat-conducting component 200 above the base 100 is gradually exposed, and its contact area with the outside air continuously increases. The heat dissipated from the surface of the heat-conducting component 200 per unit time increases accordingly, thereby achieving a stepless increase in heat dissipation rate. During the entire lifting process, the base 100 always maintains a sealed connection with the container, and the opening of the container is not opened. Therefore, external impurities cannot enter the container, and the contents will not spill out. At the same time, the user can stop the movable cover 300 at any height position according to actual needs to obtain the required heat dissipation speed.

[0024] It should be emphasized that the core improvement of this embodiment lies in the following: using the heat-conducting component 200 as a fixed channel for heat transfer from the inside of the container to the outside, and using the adjusting component 400 to drive the movable lid 300 to move up and down continuously relative to the heat-conducting component 200, thereby controlling the heat exchange area between the heat-conducting component 200 and the outside air in a continuously changing manner. This structure breaks away from the conventional mindset that the container lid must be completely removed or opened significantly to accelerate heat dissipation, and realizes free adjustment of the heat dissipation rate while the lid is always in a closed installation state. It fundamentally solves the two major technical problems of impurity intrusion and content leakage caused by opening the lid for heat dissipation, and has the functions of heat preservation, dust prevention, spill prevention and stepless heat dissipation. The structure is compact and easy to operate.

[0025] It should be noted that this application does not limit the connection method between the base 100 and the container. Specifically, it can be connected to the container opening using methods such as threads, snap-fit, or interference fit. The following only provides threaded connection methods for reference, such as... Figure 1 and Figure 3 The base 100 is an annular cap structure, and its inner wall is provided with threads for connection with the container.

[0026] like Figure 4 and Figure 6 In this embodiment, the base 100 includes a first annular cover 102 with a through hole 101, a first cavity 103, and a first insulation layer 104. The through hole 101 is disposed through the top of the first annular cover 102, and the heat-conducting element 200 is disposed through the through hole 101. The heat-conducting element 200 is fixedly connected to the inner wall of the through hole 101. This ensures that the heat-conducting element 200 is stably installed on the base 100, preventing loosening while ensuring that heat is effectively conducted upward from the inside of the container through the heat-conducting element 200. The first cavity 103 is disposed inside the first annular cover 102, and the first insulation layer 104 is filled inside the first cavity 103. The first insulation layer 104 can significantly reduce the heat loss from the base 100 to the outside, preventing the heat inside the container from being unnecessarily lost from the edge of the cover, thereby maintaining a good insulation effect when the movable cover 300 completely covers the heat-conducting element 200.

[0027] like Figure 1 and Figure 6 In this embodiment, the movable cover 300 includes a second annular cover 301, a second cavity 302, and a second insulation layer 303. The second annular cover 301 is slidably sleeved with the heat-conducting component 200, which ensures that the movable cover 300 can smoothly rise and fall along the outer wall of the heat-conducting component 200 to achieve stepless adjustment of the heat dissipation area, and also ensures that the two fit tightly to ensure the heat conduction effect. The second cavity 302 is disposed inside the second annular cover 301, and the second insulation layer 303 is filled inside the second cavity 302. The second insulation layer 303 can effectively block the heat transferred upward by the heat-conducting component 200 when the movable cover 300 covers the heat-conducting component 200, effectively reducing heat loss.

[0028] like Figure 1 and Figure 6 In this embodiment, the adjusting component 400 includes a screw 401 and an internally threaded cylinder 402. The internally threaded cylinder 402 passes through the top center of the heat-conducting outer cover 201 and is fixedly connected to the heat-conducting outer cover 201. The screw 401 is installed at the center of the upper inner surface of the movable cover 300 and is threadedly connected to the internally threaded cylinder 402. This ensures that when the user rotates the movable cover 300 to raise it until the heat-conducting component 200 is fully exposed to the external environment, the screw 401 still maintains effective thread engagement with the internally threaded cylinder 402 and does not disengage, thereby maximizing the heat dissipation area and further improving the heat dissipation effect.

[0029] The working principle of the adjustment component 400 is as follows: Figure 1 and Figure 6 The user manually rotates the movable cover 300, causing the screw 401 fixed at the center of its inner upper surface to rotate. Since the screw 401 is threadedly connected to the internal threaded cylinder 402 fixed at the center of the top of the heat-conducting outer cover 201, and the internal threaded cylinder 402 is stationary relative to the heat-conducting outer cover 201, the screw 401 generates axial displacement during rotation, thereby driving the movable cover 300 to slide along the outer wall of the heat-conducting outer cover 201. When the screw 401 rotates in the forward direction, the movable cover 300 rises, increasing the area of ​​the side wall of the heat-conducting outer cover 201 exposed to the outside, thus increasing the heat dissipation rate. When rotating in the reverse direction, the movable cover 300 falls, reducing the exposed area and decreasing the heat dissipation rate. The self-locking characteristic of the threaded engagement allows the movable cover 300 to be continuously and precisely stopped at any height, thereby achieving continuous and precise adjustment of the heat dissipation rate. Throughout the process, the base 100 remains sealed to the container, preventing impurities from entering and contents from spilling.

[0030] like Figure 3 and Figure 6In this embodiment, a sealing gasket 500 is provided inside the first annular cover 102, and the sealing gasket 500 is fitted onto the outer wall of the heat-conducting component 200 near the bottom. The sealing gasket 500 can be pressed tightly when the first annular cover 102 is connected to the container opening, filling the tiny gaps between the first annular cover 102, the inner wall of the container, and the heat-conducting component 200, thereby ensuring the sealing performance after the first annular cover 102 is connected to the container, effectively preventing the contents of the container from leaking from the edge of the cover during pouring or shaking, and also preventing external gas or impurities from entering the container from the connection point.

[0031] like Figure 6 In this embodiment, when the movable cover 300 completely covers the heat-conducting component 200, the distance between its bottom end and the top end of the heat-conducting component 200 is less than the length of the screw 401. This ensures that when the user rotates the movable cover 300 to its maximum height (i.e., the bottom end of the movable cover 300 is higher than the top end of the heat-conducting component 200, so that the heat-conducting component 200 is completely exposed to the external environment), the screw 401 always maintains effective thread engagement with the internal threaded cylinder 402 and will not disengage.

[0032] Example 2 It is understandable that in Embodiment 1, the height of the heat-conducting component 200 is fixed, and the length of its bottom end extending into the container is also fixed. To achieve good heat dissipation, the heat-conducting component 200 typically needs to be in direct contact with the contents of the container to utilize the heat capacity of the contents for efficient heat transfer. However, in actual use, the contents of the container are not always full. For example, when the container contains only half a cup or less of hot beverage or soup, the fixed-height heat-conducting component 200 may not be able to contact the liquid surface, causing heat to rely primarily on air conduction, significantly reducing heat dissipation efficiency and thus greatly affecting the heat dissipation effect.

[0033] like Figures 1 to 3 To solve the above problems, the heat-conducting component 200 includes a heat-conducting outer cover 201, a strip-shaped through groove 202, and a heat-conducting inner cover 203. The heat-conducting outer cover 201 is disposed through the base 100, and the heat-conducting inner cover 203 is slidably inserted into the heat-conducting outer cover 201. The heat-conducting inner cover 203 and the heat-conducting outer cover 201 are interference-fitted. Several strip-shaped through grooves 202 are distributed circumferentially along the side wall of the heat-conducting outer cover 201 above the base 100.

[0034] Working principle of heat-conducting component 200: such as Figure 5The heat-conducting outer cover 201 is installed through the base 100, with its bottom end in thermal contact with the inside of the container, conducting the heat of the contents upwards along the heat-conducting outer cover 201; the heat-conducting inner cover 203 is slidably inserted into the heat-conducting outer cover 201 and the two are interference-fitted. When the liquid level of the contents of the container is low, the user can manually push the heat-conducting inner cover 203 downwards to extend it from the bottom of the heat-conducting outer cover 201, thereby extending the total length of the heat-conducting component 200 to contact the contents at a lower liquid level. The interference fit ensures that the heat-conducting inner cover 203 remains in the extended position by friction when there is no external force; if Several strip-shaped channels 202 are distributed circumferentially along the side wall of the heat-conducting outer cover 201 above the base 100. These strip-shaped channels 202 not only increase the contact area between the heat-conducting outer cover 201 and the outside air, but also form a vertical air convection channel. When the movable cover 300 rises to expose the strip-shaped channels 202, hot air can flow along the strip-shaped channels 202 and dissipate, thereby significantly improving the heat dissipation efficiency. At the same time, the sliding insertion structure between the heat-conducting inner cover 203 and the heat-conducting outer cover 201 allows the overall height of the heat-conducting component 200 to be flexibly adjusted according to the actual liquid level.

[0035] It should be emphasized that the core improvement of this embodiment lies in the design of the heat-conducting component 200, which includes a heat-conducting outer cover 201, strip-shaped channels 202, and a heat-conducting inner cover 203 that can slide along its inner wall and is interference-fitted. When the liquid level in the container is low, the user can manually push the heat-conducting inner cover 203 downward to extend it from the bottom of the heat-conducting outer cover 201, thereby extending the total length of the heat-conducting component 200 to directly contact the contents and ensure unobstructed heat conduction path. At the same time, the heat-conducting outer cover 201 has several strip-shaped channels 202 circumferentially opened on the side wall above the base 100, which increases the heat dissipation area and forms a vertical convection channel. Combined with the lifting and lowering adjustment of the movable cover 300, efficient air convection heat dissipation can be achieved. This structure overcomes the technical defect of poor heat dissipation effect of the existing fixed-height heat-conducting component 200 in the non-full cup state, enabling the container cover to adapt to different liquid levels and ensuring that the heat dissipation effect is always stable and reliable without changing the sealing connection between the base and the container.

[0036] like Figures 5 to 6 In this embodiment, an annular hole is opened at the top center of the heat-conducting inner cover 203 for the internally threaded cylinder 402 to pass through, and an annular piston 204 is fixedly installed in the annular hole. The heat-conducting inner cover 203 is slidably sleeved with the internally threaded cylinder 402 through the annular piston 204. When the heat-conducting inner cover 203 slides up and down relative to the internally threaded cylinder 402, the annular piston 204 always maintains a sealed contact with the outer wall of the internally threaded cylinder 402, preventing the liquid in the container from seeping into the interior of the heat-conducting outer cover 201 through the gap between the heat-conducting inner cover 203 and the internally threaded cylinder 402. This achieves the expansion and contraction adjustment of the heat-conducting inner cover 203 while maintaining the sealing performance of the container lid, preventing leakage of contents or external impurities from entering the container through this path.

[0037] like Figure 6In this embodiment, the internally threaded cylinder 402 passes through the top of the heat-conducting inner cover 203, and the bottom end of the internally threaded cylinder 402 is located inside the heat-conducting outer cover 201. A stop 403 is installed at the bottom end of the internally threaded cylinder 402 to prevent the heat-conducting inner cover 203 from detaching from the internally threaded cylinder 402. The stop 403 can abut against its top inner wall or annular piston 204 when the heat-conducting inner cover 203 extends downward to its limit position, thereby limiting the maximum downward stroke of the heat-conducting inner cover 203, preventing the heat-conducting inner cover 203 from completely slipping off the internally threaded cylinder 402, ensuring that the heat-conducting inner cover 203 always maintains a sliding sleeve relationship with the internally threaded cylinder 402, and improving the reliability and safety of the telescopic adjustment structure.

[0038] like Figure 6 In this embodiment, a rubber ring 205 is provided on the inner wall of the heat-conducting inner cover 203 near its bottom end, and an annular notch is provided along the edge of the bottom end of the heat-conducting outer cover 201, with a matching sealing ring 206 installed at the annular notch. It should be noted that when it is necessary to further extend the total length of the heat-conducting component 200 to contact the contents at extremely low liquid levels, the user can take another annular heat-conducting component and insert it into the heat-conducting inner cover 203 from below. The rubber ring 205 is interference-fitted with the inserted component and provides friction, so that the inserted component will not fall off by itself under the action of gravity, thereby flexibly increasing the heat-conducting length. The bottom end of the heat-conducting outer cover 201 has an annular notch along the edge, and a matching sealing ring 206 is installed at the annular notch. During the process of the heat-conducting inner cover 203 sliding up and down relative to the heat-conducting outer cover 201, the sealing ring 206 always maintains elastic compression and sealing with the outer wall of the heat-conducting inner cover 203, preventing the liquid in the container from leaking outward along the sliding gap between the heat-conducting inner cover 203 and the heat-conducting outer cover 201, and ensuring that the overall sealing performance of the container lid is not affected during the extension and retraction adjustment.

[0039] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
