Description

Insulated container with an extendable inner cup for heat dissipation Technical Field

[0001] The present application relates to a thermal insulation container with an inner cup that can be extended to dissipate heat. The application relates to a thermal insulation container with adjustable thermal conductivity as needed, particularly a container in which an inner cup that can dissipate heat is added to a stainless steel vacuum container such as a thermos cup or a thermos can. The heat dissipation is achieved by simply extending the inner cup, and a fixing module can be used to fix the inner cup and extend it, with only a portion of it exposed for heat dissipation. Background Art

[0002] In order to achieve better insulation effect, the thermos cups or flasks on the market usually have a two-layer shell and a vacuum in the middle of the two layers. However, as the insulation effect gets better and better, after being put into high-temperature water, the water will remain very hot for a long time. Although this is an advantage, if you need to drink the water directly, or start drinking after making tea or Chinese medicine, it will be very hot and you may have to wait a long time to swallow it smoothly.

[0003] To solve this problem, the thermos cup or flask needs to have a good heat-insulating effect when it needs to maintain heat, and when it needs to dissipate heat quickly like an ordinary teacup, it can also smoothly conduct the heat away. However, since these two things are originally in a contradictory state, there have been no relevant records or practical applications in relevant literature or market products so far.

[0004] Summary of the Invention

[0005] Some thermoses and flasks currently on the market still use single-layer insulation, while most others have adopted double-layer, vacuum-insulated technology to achieve thermal insulation or insulation. However, regardless of whether these containers use insulation or vacuum-insulated technology, the limitation of only being able to insulate is a significant problem in many applications. For example, when brewing scented or herbal tea, using a thermos that only insulates can lead to a long wait before the tea is ready. This is because these insulated cups are designed to insulate for as long as possible, typically maintaining temperatures above 90 degrees Celsius for over four hours. Therefore, many users resort to opening the lid to allow the tea in the cup to cool quickly. However, this often leads to accidental tipping over of the cup, causing the hot water to spill, which can be dangerous. Furthermore, if you fill a thermos with water and place it directly in the refrigerator, the low temperature of the refrigerator won't be able to exchange heat with the water inside the thermos due to the insulated design. Therefore, even if you leave it in the thermos for a long time, the water inside will have a hard time cooling down or even freezing. This is because the insulated design of the thermos prevents heat transfer between the thermos and the outside world, and the low temperature of the refrigerator can't penetrate the insulation layer. Therefore, even after being in the refrigerator for a while, the temperature of the water inside the thermos will still cool very slowly. Therefore, if users want to cool or freeze the water quickly, they can only open the lid before placing it in the refrigerator to cool. However, this will cause other odors from the refrigerator to enter the thermos, causing the flavors of different foods to cross-contaminate.

[0006] The main purpose of this application is to disclose a novel structural principle that can simultaneously solve these two mutually contradictory physical problems. The method is to add a layer of heat-dissipating inner cup in the stainless steel vacuum container of the thermos cup or thermos flask, and then smoothly execute the heat dissipation or insulation state by extending or retracting the inner cup, so that the thermos cup or thermos flask can have the traditional vacuum insulation performance when it is necessary to maintain heat; and when rapid heat dissipation is required, a simple structure can be used to allow the heat-dissipating inner cup to rise to a naked state. Without the protection of the vacuum insulation layer, the heat inside the inner cup can be dissipated by direct heat conduction from the shell.

[0007] To achieve this goal, the present application proposes several different implementation modes and embodiments. By setting different types of fixed module structures, the user can adjust the insulation type inside the insulation container by raising or lowering the inner cup.

[0008] The structure of this thermal insulation container is mainly composed of two different heat-conducting materials. The outer layer is usually made of two layers of stainless steel and is vacuum-insulated, while the inner cup is made of a material that can dissipate heat and usually adopts a single-layer structure. Therefore, when the inner cup is extended and exposed outside the vacuum insulation layer, the heat dissipation material of the inner cup can help heat to be quickly transferred to the outside, causing the temperature inside the container to drop rapidly; when the inner cup drops into the vacuum insulation layer, it turns back into the original traditional vacuum-insulated thermos cup, which can effectively block the conduction of heat, and because it is a true three-layer shell, it can insulate more effectively than traditional thermos cups with two-layer shells.

[0009] This innovative, though simple, design prevents hot tea from scalding and becoming uneatable in a typical thermos, or prevents ice from remaining unmelted. You can also turn the inner cup of a thermos or box to heat dissipation mode, place it in the refrigerator, and then return it to heat-insulating mode the next day, ensuring a full day of cold drinks. Furthermore, while in heat dissipation mode, users can still hold onto the vacuum-insulated outer shell, preventing burns.

[0010] To sum up, under such a structure, the use value of the original vacuum insulated thermos cup or insulation box can be greatly improved, and the technical solution of this application has many obvious advantages and effects compared with the existing technology that can only unilaterally insulate and keep warm. It can be expected that this application will have extremely high practical application value. Other specific and detailed implementation methods will be described below.

[0054] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0055] Please refer to Figure 1. The present application is a heat-insulating container with an extendable inner cup for heat dissipation, which includes an insulation shell 1, a heat-dissipating inner cup 2, a fixing module 3, and a cup cover 6. The insulation shell 1 is formed by at least one layer of insulation structure to form a container shape. It can be a common vacuum travel cup made of two layers of stainless steel, or a single-layer insulation box made of foam material. The main feature is that a heat-dissipating inner cup 2 can be placed in the container of the insulation shell 1. Since the heat-dissipating inner cup 2 is made of the opposite material to the insulation shell 1 and is composed of a heat-dissipating structure, its shell is usually a single-layer structure, which makes it easier to conduct heat out. The heat-dissipating inner cup 2 can be partially extended from the insulation shell 1, leaving a portion of the heat-dissipating inner cup 2 exposed. , to dissipate heat. When the heat dissipating liner cup 2 is partially extended, it can be temporarily locked on the thermal insulation shell 1 through the fixing module 3, so that the heat dissipating liner cup 2 will not fall down. Therefore, the heat dissipating liner cup 2 can dissipate heat to its contents directly through the heat dissipating material of the shell without opening the cup cover 6; and when the heat dissipating liner cup 2 is fully retracted into the thermal insulation shell 1, it can also be fixed by the fixing module 3, that is, traditional heat insulation, and at the same time, it will not shake or fall out of the heat dissipating liner cup 2 when carried. Overall, since the thermal insulation container has a three-layer shell, the thermal insulation efficiency of the three-layer shell will definitely be better than that of a traditional thermal insulation cup or thermal insulation box with only two layers of shell.

[0056] The heat-insulating shell 1 can be composed of at least two layers of stainless steel shells, an inner layer and an outer layer, with a hollow and sealed state between the two layers and evacuated to form a vacuum, so it has good heat insulation effect. However, when using a traditional vacuum insulation cup, a situation often occurs. That is, after putting high-temperature contents, such as boiling water to brew tea or herbal bags, once the lid is closed, due to the good heat preservation effect, the temperature inside is very hot even after being placed for more than 4 hours, and it is impossible to drink smoothly. This problem has troubled people for a long time. At present, it can only be solved by opening the lid, but this is easy to cause accidents such as spilling hot water or being contaminated by dropped objects. Moreover, when the lid is opened, it cannot be carried around, and closing the lid will cause a dilemma in which it cannot be cooled.

[0057] In the present application, the heat dissipation inner cup 2 can be partially extended outside the heat-insulating shell 1 to dissipate heat, or the whole cup can be taken out and placed, which can accelerate the heat dissipation. At this time, the cup cover 6 of the heat dissipation inner cup 2 does not need to be opened, thus avoiding the problems encountered by traditional vacuum insulation cups. In addition to the benefit of heat dissipation, extending a portion of the heat dissipation inner cup 2 outside the heat-insulating shell 1 also allows the heat-insulating shell 1 to be held by hand without being burned due to the heat-insulating properties of the heat-insulating shell 1. In order to allow the heat dissipation inner cup 2 to partially extend outside the heat-insulating shell 1 and not fall down due to gravity, a fixing module 3 is required. This fixing module 3 can be set inside or outside the heat-insulating shell 1 or the heat dissipation inner cup 2 or its cup cover 6, and can be composed of a snap-fit ​​structure, a tight clamping structure, a magnetic structure, or an elastic base structure.

[0058] Therefore, the following provides a detailed description of various embodiments of the various fixing modules 3. First, the most commonly used snap-on design is discussed. The fixing module 3 is ring-shaped and fits over the opening of the insulation shell 1. At least one snap-on design 8, which can be made of a non-slip material such as silicone, is provided around the inner periphery of the fixing module 3 to tightly clamp the heat dissipating liner 2. At least one control button, typically two, is provided around the outer periphery of the fixing module 3, allowing for easy finger-pressing. Pressing the control button 7 releases the snap-on design 8 from the heat dissipating liner 2, allowing it to partially or fully extend upward. Once partially extended, the control button 7 can be released to tightly clamp the heat dissipating liner 2 again, securing it in its partially exposed position. This exposed portion, free from the insulation protection of the vacuum insulation shell 1, can function as a heat dissipator. When heat dissipation is no longer required, the heat dissipating liner 2 can be returned to its original position, fully protected by the vacuum insulation shell 1 for insulation.

[0059] Please refer to Figures 2 and 3. In another embodiment, this fixing module 2 is arranged at the opening of the thermal insulation shell 1, and at least one buckle 8 is provided at the periphery thereof where it connects with the heat dissipation liner cup 2. Two positioning points 9 are provided around the heat dissipation liner cup 2. The positioning point 9 has a concave structure and can be engaged with the convex buckle 8. Therefore, when the heat dissipation liner cup 2 is partially extended, it can be fixed on the thermal insulation shell 1 and will not slide down. By pressing the control button 7, the buckle 8 can be disengaged from the positioning point 9, so that the heat dissipation liner cup 2 can be completely taken out or retracted into the thermal insulation shell 1. When the heat dissipation liner cup 2 is retracted into the thermal insulation shell 1, the heat insulation plate 5 under the cup mouth 4 can be used to allow the heat dissipation liner cup 2 to maintain complete insulation.

[0060] The heat dissipation liner cup 2 can be manually extended out of the heat-insulating shell 1, or manually retracted into the heat-insulating shell 1, wherein it can also be extended automatically, as shown in Figure 4, which is a spring module 11 provided at the bottom of the heat-insulating shell 1 container. When the control button 7 is pressed, the heat dissipation liner cup 2 can be automatically extended by the accumulated elastic force, and in order to avoid it from being extended too quickly, a buffer module 12 can be provided at the contact point with the heat-insulating shell 1. Through friction damping, or air vent speed limiting exhaust, or damping gears, the heat dissipation liner cup 2 can be slowly extended in a slow manner, and its heat dissipation material shell is exposed to the outside to perform heat dissipation 20. Subsequently, the heat dissipation liner cup 2 can be pressed back into the heat-insulating shell 1 by manual pressing, and then the heat dissipation liner cup 2 is automatically locked by the buckle 8 of the fixing module 3.

[0061] In another embodiment, please refer to Figure 5. The fixing module 3 is arranged at the bottom of the heat-insulating shell 1 container and is composed of an elastic base 10. The elastic base 10 is provided with a spring module 11 and a self-locking mechanism module 13 to form a self-locking elastic base 10. When the heat dissipation liner cup 2 is pressed downward, it can be automatically locked on the elastic base 10 at the bottom. When pressed again, it can be unlocked and the heat dissipation liner cup 2 is automatically extended by the force of the spring module 11. Therefore, there is no need to provide the buckle 8 and the control button 7. The buffer module 12 can also be used to allow the heat dissipation liner cup 2 to be slowly extended in a slow manner, and the shell of the heat dissipation material is exposed to the outside to perform heat dissipation 20.

[0062] Please refer to Figure 6, which shows another embodiment. The fixing module 3 adopts a tight clamping structure, so the heat dissipation liner cup 2 can be partially extended and fixed to the thermal insulation shell 1 by pressing or rotating. Among them, the rotation method is to set a spiral tightening mechanism 14 at the opening of the thermal insulation shell 1, and use the rotating thread to create a gradually shrinking opening, so that the heat dissipation liner cup 2 can be fixed to the thermal insulation shell 1 after being pulled out, similar to the telescopic fixing structure of a trekking pole. The biggest advantage of using this method is that there is no need for a positioning point 9, and the telescopic length of the heat dissipation liner cup 2 after being pulled out can be flexibly determined.

[0063] Please refer to Figure 7, which shows another embodiment. The fixing module 3 is provided at the lower end of the cup cover 6. Normally, the cup cover 6 can be locked to the cup cover locking ring 26 at the upper end of the heat-insulating shell 1, and the heat-dissipating inner cup 2 is also fixed within the heat-insulating shell 1. The cup cover 6 can be released from the lock of the heat-insulating shell 1 by rotating or pressing. In addition, the inner shell of the heat-insulating shell 1 can be provided with an inwardly concave slide rail 23 and a protruding platform 24. The outer side of the heat-dissipating inner cup 2 can be provided with a plurality of latches 25. By aligning the latches 25 with the slide rail 23, the heat-dissipating inner cup 2 can move up and down. When the heat-dissipating inner cup 2 moves upward to above the platform 24, it can be rotated left and right and then lowered so that the latches 25 can be placed on the platform 24. The heat-dissipating inner cup 2 can then be fixed in a partially extended state for heat dissipation. Alternatively, the latches 25 can be rotated again to align with the slide rail 23, and the heat-dissipating inner cup 2 can be moved back to the bottom.

[0064] The thermal insulation shell 1 or the heat dissipation inner cup 2 can be made of metal, ceramic, glass, plastic, graphene, wood, or foam material, or can be made of composite materials, such as metal plated with a layer of ceramic; and when the heat dissipation inner cup 2 is taken out, the thermal insulation shell 1 can also be used as another container, as shown in Figure 8, and the two can be made of different materials; for example, the thermal insulation shell is made of two layers of stainless steel material 21, and the heat dissipation inner cup is made of titanium alloy material 22 or ceramic material.

[0065] 9 and 10 , the cup cover 6 can tightly cover the heat dissipating inner cup 2 at the cup mouth 4 . A filter 30 can be provided inside the cup cover 6 or at the cup mouth 4 . The cup cover 6 can be provided with a flip-up switch 31 or an attached straw device 32 . The cup cover 6 can also be provided with a portable handle 33 .

[0066] As shown in Figure 11, the container shape formed by the heat-insulating shell 1 or the heat-dissipating inner cup 2 can be a heat-insulating cup, a heat-insulating box, a heat-insulating lunch box 34, a simmering pot, or a simmering pot 35. The heat-dissipating inner cup 2 can be extended in the direction of up and down movement or front and back and left and right movement. A simmering pot handle 36 can be provided on the outside of the heat-insulating shell 1.

[0067] As shown in FIG12 , the heat-insulating shell 1 may be provided with an electric heating and cooling module 40 , which can heat or cool the contents of the heat-dissipating inner cup 2 , and the cup cover 6 may be provided with a temperature display module 41 , which can instantly display the current internal temperature.

[0068] As can be seen from the above embodiments, compared with the prior art, the present application has the following advantages:

[0069] 1. None of the previously known vacuum insulated containers utilize an extendable inner cup to achieve convenient and rapid heat dissipation. Conventional vacuum insulated bottles often contain hot water, often resulting in the water being too hot. For those who need to cool the brewed beverage before drinking it, the only way to do so is to open the cup, which carries the risk of spilling the hot water. The present application cleverly utilizes an extendable inner cup to achieve this important function.

[0070] 2. In the current application field of thermos, it is not possible to put it into the refrigerator directly after filling it with water to obtain ice water. Due to the vacuum insulation, the low temperature outside cannot be transmitted into the interior, so the only way is to open the cup mouth, but this will cause the problem of refrigerator smell in the cup, or you have to use other containers to make ice water first, and then fill the ice water into the thermos when needed, which is very inconvenient. The present application can also use the method of extending the inner liner cup to directly refrigerate or freeze the contents of the thermos.

[0071] 3. In addition to simply achieving the functions of heat insulation or heat dissipation, this application can also fine-tune the heat-insulating time or heat conduction speed in the thermal insulation container by controlling the extension distance of the heat dissipation inner cup. This can produce more diverse applications, such as accurately controlling the temperature of drinking water after a few hours.

[0072] 4. This application adopts a very simple method, which solves the long-standing demand for heat dissipation of thermos cups. This can be very beneficial in industrial production because the cost will be very low, and there will be an opportunity to drive another innovation in the thermos cup industry. Because this demand has existed for a long time, but there has been no effective method, this application highlights its extremely high value.

[0073] In summary, through the above-mentioned implementation process, this application is a thermal insulation container with an extendable inner cup for heat dissipation, which has not been seen before in various documents or known commercial items. However, due to its ingenious and simple structure, easy implementation, and great effectiveness, this application is truly a progressive and novel thermal insulation container, which meets the application requirements for a patent, and thus an application is filed in accordance with the law.

[0074] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
