Description

Technical Field

[0001] The present invention relates to a heat-insulating container with an inner cup that can be extended to dissipate heat, and is a heat-insulating container that can adjust thermal conductivity as needed, and in particular to a heat-insulating container in which an inner cup that can dissipate heat is added to a stainless steel vacuum container such as a heat-insulating cup or a heat-insulating can, and heat is dissipated by simply extending the inner cup, and a fixing module can be used to fix and extend the inner cup, with only a portion of the inner cup exposed to dissipate heat. 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 at a very high temperature for a long time. Although this is an advantage, if you want 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 must have a good heat-insulating effect when it is necessary to maintain heat, and be able to smoothly conduct heat away when it is necessary to dissipate heat quickly like a normal teacup. However, since these two things are originally in a contradictory state, there have been no relevant records or practical applications in existing literature or market products so far. Summary of the invention

[0004] Some thermos cups or flasks on the market still use single-layer insulation materials, while most others have already used double-layer and vacuum insulation technology to achieve insulation or heat insulation. However, regardless of whether these insulation containers use insulation materials or vacuum insulation technology, the limitation of only being able to insulate is very troubling in many applications. For example, when users are brewing flower tea or Chinese herbal tea, if they use a thermos cup that can only insulate, a situation will arise, that is, the user will have to wait a long time before drinking the brewed tea, because these insulated cups are designed to insulate for as long as possible, usually maintaining a temperature of more than 90 degrees for more than 4 hours. Therefore, many users have to open the lid to allow the tea in the thermos cup to cool down quickly, but in this way, they will often accidentally knock over the cup and let the hot water spill out, which is sometimes unavoidable and dangerous. In addition, if you want to put water in a thermos cup and then put it directly into the refrigerator, at this time, since the thermos container is an insulated design, the low temperature of the refrigerator cannot exchange heat with the water temperature inside the thermos cup. Therefore, even if it is left for a long time, it is difficult to lower the temperature of the water in the cup or even freeze it. This is because the insulated thermos cup design prevents mutual heat conduction, that is, the heat in the thermos cup cannot be exchanged to the outside, and the low temperature of the refrigerator cannot enter the cup through the insulation layer of the thermos cup. Therefore, even if it is placed in the refrigerator for a period of time, the water temperature in the thermos cup will still drop very slowly. Therefore, if the user wants to cool or freeze the water quickly, he can only open the cup lid first and then put it in the refrigerator to cool it down, but this will cause other odors in the refrigerator to enter the thermos cup, resulting in the problem of different foods tasting each other.

[0005] The main purpose of the present invention is to disclose a novel structural principle that can solve these two mutually contradictory physical problems at the same time. The method is to add a layer of heat-dissipating inner liner 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 liner 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 liner cup to rise to a naked state. Without the protection of the vacuum insulation layer, the heat inside the inner liner cup can be dissipated by direct heat conduction from the shell.

[0006] To achieve this object, the present invention 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.

[0007] 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 the 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 real three-layer shell, it can insulate more effectively than traditional thermos cups with two-layer shells.

[0008] This innovative structure, although simple, can prevent hot tea from being too hot to drink in a regular thermos cup, or prevent the ice cubes in the cup from not melting. You can also raise the inner cup of the thermos cup or the thermos box to the heat dissipation mode, put it in the refrigerator, take it out the next day and lower it to the heat-insulating mode, so that you can have cold drinks all day long. In addition, when it is raised to the heat dissipation mode, you can still hold the vacuum heat-insulating shell to prevent the user from getting burned.

[0009] To sum up, under such a structure, the use value of the original vacuum insulated cup or insulation box can be greatly improved, and the technical solution of the present invention has many obvious advantages and effects compared with the existing technology that can only unilaterally insulate and keep warm. It can be expected that the present invention will have extremely high practical application value. Other specific and detailed implementation methods will be described as follows.

[0053] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0054] See also Figure 1 As shown, the present invention is a heat-insulating container with an inner cup that can be extended to dissipate heat, comprising a heat-insulating shell 1, a heat-dissipating inner cup 2, a fixing module 3, and a cup cover 6. The heat-insulating shell 1 is formed of at least one layer of heat-insulating structure to form a container shape, which can be a common vacuum travel cup made of two layers of stainless steel, or a heat-insulating box made of a single-layer foaming material, etc., mainly in that a heat-dissipating inner cup 2 can be placed in the container of the heat-insulating shell 1, and because the heat-dissipating inner cup 2 is made of the opposite material to the heat-insulating shell 1 and is composed of a heat-dissipating structure, its shell is usually a single-layer structure, which is easier to conduct heat out, and the heat-dissipating inner cup 2 can be partially extended from the heat-insulating shell 1, so that a part of the heat-dissipating inner cup 2 is exposed to improve heat dissipation. When the heat dissipation liner cup 2 is partially extended, it can be temporarily locked on the heat preservation shell 1 through the fixing module 3, so that the heat dissipation liner cup 2 will not fall down. Therefore, the heat dissipation liner cup 2 can directly dissipate the heat of its contents through the heat dissipation material of the shell without opening the cup cover 6; and when the heat dissipation liner cup 2 is completely retracted into the heat preservation shell 1, it can also be fixed by the fixing module 3, that is, traditional heat insulation and heat preservation, and at the same time, the heat dissipation liner cup 2 will not shake or fall out when carried. On the whole, since the heat preservation container has a three-layer shell, the heat preservation efficiency of the three-layer shell will definitely be better than that of the traditional heat preservation cup or heat preservation box with only two layers of shell.

[0055] 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 flask, a situation often occurs. After putting in high-temperature contents, such as boiling water to brew tea or herb bags, once the lid is closed, due to the good heat preservation effect, even if it is placed for more than 4 hours, the temperature inside is very hot and cannot be drunk 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 the temperature cannot be reduced.

[0056] In the present invention, the heat dissipation inner cup 2 can be partially extended out of the heat preservation 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, so the problems encountered by the traditional vacuum insulation cup can be avoided. In addition to the benefit of heat dissipation, the heat dissipation inner cup 2 is partially extended out of the heat preservation shell 1. Due to the heat insulation characteristics of the heat preservation shell 1, the heat preservation shell 1 can be held by hand without being burned. In order to allow the heat dissipation inner cup 2 to partially extend out of the heat preservation shell 1 and not fall down due to gravity, a fixing module 3 is required. This fixing module 3 can be set in the heat preservation shell 1 or the heat dissipation inner cup 2 or inside or outside its cup cover 6, and can be composed of a snap structure, a tight clamp structure, a magnetic structure, or an elastic base structure.

[0057] Therefore, the following is a detailed description of the various embodiments of the various fixing modules 3. First, the most commonly used buckle structure is used. The fixing module 3 is in the shape of a ring and can be fitted on the opening of the heat-insulating shell 1. At least one buckle 8 is provided around the inner ring of the fixing module 3, which can be made of anti-slip materials such as silicone and can tightly clamp the heat-dissipating liner cup 2. At least one control button is provided around the outer ring of the fixing module 3, which can usually be two, so that it is convenient to press each other with fingers. By pressing the control button 7, the buckle 8 can release the heat-dissipating liner cup 2, so that the heat-dissipating liner cup 2 can be extended upward in part or in full, and when a part is extended, the control button 7 can be released to tightly clamp the heat-dissipating liner cup 2 again, so that it is fixed in a partially exposed state. This exposed part, because there is no heat insulation protection of the vacuum heat-insulating shell 1, can perform the heat dissipation function. When heat dissipation is not needed, the heat-dissipating liner cup 2 only needs to be pushed back to its original position, and it can be completely protected by the vacuum heat-insulating shell 1 to perform the heat insulation function.

[0058] See also Figure 2 and Figure 3In another embodiment, the fixing module 2 is arranged at the opening of the heat-insulating shell 1, and at least one buckle 8 is provided at the periphery thereof where it is connected to the heat-insulating inner cup 2. Two positioning points 9 are provided around the heat-insulating inner cup 2. The positioning points 9 have a concave structure and can be engaged with the convex buckle 8. Therefore, when the heat-insulating inner cup 2 is partially extended, it can be fixed on the heat-insulating 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-insulating inner cup 2 can be completely taken out or retracted into the heat-insulating shell 1. When the heat-insulating inner cup 2 is retracted into the heat-insulating shell 1, the heat-insulating plate 5 under the cup mouth 4 can be used to allow the heat-insulating inner cup 2 to maintain complete heat insulation.

[0059] The heat dissipation inner 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, see Figure 4 As shown, a spring module 11 is provided at the bottom of the heat-insulating shell 1 container. When the control button 7 is pressed, the heat-dissipating liner cup 2 can be automatically extended by the accumulated elastic force, and in order to avoid extending 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-dissipating liner cup 2 can be slowly extended in a slow manner, and the shell of the heat-dissipating material is exposed to the outside to perform heat dissipation 20. Subsequently, the heat-dissipating liner cup 2 can be pressed back into the heat-insulating shell 1 by manual pressing, and then the heat-dissipating liner cup 2 can be automatically locked through the buckle 8 of the fixing module 3.

[0060] In another embodiment, see 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 it is 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. Among them, the heat dissipation liner cup 2 can also be slowly extended in a slow manner through the buffer module 12, and its heat dissipation material shell is exposed to the outside to perform heat dissipation 20.

[0061] See also Figure 6, is another embodiment, the fixing module 3 adopts a tight clamping structure, so the heat dissipation liner cup 2 can be partially extended and fixed on the thermal insulation shell 1 by pressing or rotating. Among them, the rotation method is to set a spiral pressing 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 on the thermal insulation shell 1 after being pulled out, similar to the zoom 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.

[0062] See also Figure 7 , is another embodiment, the fixing module 3 is arranged at the lower end of the cup cover 6, and the cup cover 6 can be locked on the cup cover locking ring 26 at the upper end of the heat-insulating shell 1 at ordinary times, and the heat-dissipating liner cup 2 is also fixed in 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, and the outer side of the heat-dissipating liner cup 2 can be provided with a plurality of latches 25. By aligning the latches 25 with the slide rail 23, the heat-dissipating liner cup 2 can move up and down. When the heat-dissipating liner cup 2 moves upward to the top of the platform 24, it can be rotated left and right and then put down, so that the latches 25 can be placed on the platform 24, and the heat-dissipating liner cup 2 can be fixed in a partially extended state for heat dissipation, or the latches 25 can be rotated again to align with the slide rail 23, and the heat-dissipating liner cup 2 can be moved back to the bottom.

[0063] The heat-insulating shell 1 or the heat-dissipating 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-dissipating inner cup 2 is taken out, the heat-insulating shell 1 can also be used as another container, such as Figure 8 As shown, the two can be made of different materials; for example, the heat-insulating shell is made of two layers of stainless steel material 21, and the heat-dissipating liner cup is made of titanium alloy material 22 or ceramic material.

[0064] See also Fig. 9 and Fig.10 The cup cover 6 can tightly cover the heat dissipation 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 a straw device 32. The cup cover 6 can also be provided with a portable handle 33.

[0065] like Fig.11As shown, the container shape formed by the heat-insulating shell 1 or the heat-dissipating inner cup 2 can be a heat-insulating cup, or a heat-insulating box, or a heat-insulating lunchbox 34, or a simmering pot, or a simmering pot 35. The heat-dissipating inner cup 2 can extend in an up-and-down direction or in a forward-and-backward and left-and-right direction. A simmering pot handle 36 can be provided on the outside of the heat-insulating shell 1.

[0066] like Fig.12 As shown, the heat preservation shell 1 may be provided with an electric heating and cooling module 40, which can heat or cool the contents of the heat dissipation liner cup 2, and the cup cover 6 may be provided with a temperature display module 41, which can instantly display the current internal temperature.

[0067] It can be seen from the above embodiments that compared with the prior art, the present invention has the following advantages:

[0068] 1. In all the known vacuum insulation containers, there is no method of using an extendable inner cup to achieve convenient and rapid heat dissipation. Compared with the previous use of vacuum insulation cups to hold hot water, people often drink too hot water. For the needs of cooling down the beverage before drinking it, the only way to cool it down is to open the cup mouth, but doing so will cause the risk of spilling the hot water. The present invention can cleverly use the extendable inner cup to achieve this important function.

[0069] 2. In the current application field of thermos cups, it is not possible to put them directly into the refrigerator to obtain ice water after filling them with water, because the low temperature outside cannot be conducted into the interior due to vacuum insulation, so the mouth of the cup can only be opened, but this will cause the problem of refrigerator odor in the cup, or other containers have to be used to make ice water first, and then fill the ice water into the thermos cup when needed, which is very inconvenient. The present invention can also use the method of extending the inner liner cup to directly refrigerate or freeze the contents of the thermos cup.

[0070] 3. In addition to simply achieving the function of heat insulation or heat dissipation, the present invention can also fine-tune the heat insulation time or heat conduction speed in the thermal insulation container by controlling the distance that the heat dissipation inner cup extends, which can produce more different applications, such as accurately controlling the temperature of the water you drink a few hours later.

[0071] 4. The present invention adopts a very simple method, which solves the long-standing demand for heat dissipation of thermos bottles. This can be very beneficial in industrial production because the cost will be very low and there will be a chance to drive another innovation in the thermos bottle industry. Because this demand has existed for a long time, but there has been no effective method, the present invention highlights its extremely high value.

[0072] In summary, through the above-mentioned implementation process, the present invention is a heat-insulating container with an inner cup that can extend to dissipate heat, which has not been seen in various documents and known commercial items before. However, due to its ingenious and simple structure and easy implementation, it can bring great benefits. Therefore, the present invention is truly a progressive and novel heat-insulating container, which meets the application requirements for invention patents, and therefore an application is filed in accordance with the law.

[0073] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
