Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a container. Background Art

[0002] Cups and other containers are essential for holding drinking liquids. When hot water is poured into a cup, it often takes a long time to cool down to the appropriate drinking temperature. This often leads to people being unable to drink water because the water in the cup is too hot when they are in a hurry, causing a lot of inconvenience.

[0003] To quickly cool the liquid in a cup, a related technique involves installing a stirring rod and a micromotor inside the cavity. The micromotor drives the stirring rod to stir the liquid, thereby rapidly dissipating the heat. However, this cooling method results in a more complex structure and higher production costs.

[0004] In addition, the related art uses a phase change reaction to lower the liquid position, but the process of the phase change reaction is uncontrollable, which directly leads to the temperature of the liquid after cooling being too high or too low, and cannot meet the user's needs. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, the present invention provides a container.

[0007] The present invention provides a container, comprising: a first container body; a second container body, arranged in the first container body; a phase change chamber, located between the first container body and the second container body; a phase change medium, arranged in the phase change chamber; and a closed medium, arranged in the phase change chamber, wherein when the container is in a static state, the liquid phase change medium and the second container body are isolated from each other by the closed medium; wherein, when the container is in a working state, the liquid phase change medium can contact with the second container body and vaporize, and the gaseous phase change medium can contact with the first container body and liquefy.

[0008] The container proposed by the present invention includes a first container body, a second container body, a phase change chamber, a phase change medium, and a sealing medium. The phase change medium is a gas-liquid phase change medium, which is liquid at room temperature. The second container body is disposed within the first container body, and the interior of the second container body can be used to store food or liquids. The phase change chamber is located between the first and second container bodies, and the phase change medium and the sealing medium are disposed within the phase change chamber. When the container is in a static state, the phase change medium is present at the bottom of the phase change chamber, and the sealing medium is isolated between the liquid phase change medium and the second container body.

[0009] When the user shakes the container, the phase change medium flows in the phase change chamber and contacts the second container body. The liquid phase change medium absorbs heat from the second container body and vaporizes into gas. Correspondingly, the gaseous phase change medium contacts the first container body and releases heat to liquefy into liquid. This cycle is repeated to cool the food or liquid in the second container body and realize the hand-warming function of the container.

[0010] In particular, since the phase change medium is a gas-liquid phase change medium and can vaporize and liquefy, this ensures that the gas-liquid phase change of the phase change medium is intense and rapid, and its efficiency far exceeds the heat conduction of ordinary solids or liquids, so that the phase change medium can absorb a large amount of heat when vaporizing and release a large amount of heat when liquefying, which greatly improves the heat exchange effect, increases the cooling rate of the hot water in the second container body and the heating rate of the first container body. At the same time, the phase change medium can be fully recycled, which is more environmentally friendly and economical.

[0011] Furthermore, when the container is in a static state, the sealing medium can isolate the liquid phase-change medium from the second container body. This ensures that the liquid phase-change medium's surface does not contact the second container body, and further isolates the liquid phase-change medium from the second container body through the sealing medium, preventing heat exchange between the liquid phase-change medium and the second container body, further improving the controllability of the cooling process.

[0012] It should be noted that the aforementioned operating state refers to the situation where a user places a hot liquid or food in the second container body, and the phase change medium is used to lower the temperature of the liquid or food. While the container is in the operating state, the user shakes the container to break through the enclosing medium and come into contact with the second container body, causing the phase change medium to undergo a continuous phase change reaction. Correspondingly, the aforementioned static state refers to the situation where the container is in a stable state, with the phase change medium separated from the second container body and the enclosing medium isolated between them. At this point, the phase change medium is liquid and does not undergo a phase change reaction.

[0013] Therefore, the container proposed by the present invention fully utilizes the gas-liquid phase change of the phase change material, can instantly absorb and release a large amount of heat, accelerate the rate of heat conduction, and greatly improve the heat exchange efficiency of the container; and can enhance the controllability of the phase change reaction through the closed medium, on the one hand, ensuring the temperature of the liquid or food after cooling, and on the other hand, preventing the user from accidentally touching the container and causing the phase change medium to undergo a phase change reaction.

[0014] The container according to the above technical solution of the present invention may also have the following additional technical features:

[0015] In the above technical solution, when the container is in a static state, the liquid level of the liquid phase change medium is lower than the outer bottom wall of the second container body.

[0016] In this technical solution, only a fixed amount of phase-change medium is contained within the phase-change chamber. When the container is in a static state, the liquid level of the phase-change medium is kept below the outer bottom wall of the second container body, creating a gap between the liquid level and the outer bottom wall of the second container body. Thus, when the container is in a static state, the liquid phase-change medium is separated from the second container body. Even if hot water is present within the second container body, the phase-change medium will not vaporize, achieving controllable cooling. Specifically, when a user needs to lower the temperature of the hot water within the second container body using the phase-change medium, they simply shake the container to bring the liquid phase-change medium into contact with the second container body.

[0017] In any of the above technical solutions, the container further includes an isolating member, which is disposed at the bottom of the second container body, and a flow gap is provided between the isolating member and the inner side wall of the first container body; wherein the isolating member defines a closed medium.

[0018] In this technical solution, the container also includes a separator, which serves as a sealing medium. Specifically, the separator is located at the bottom of the second container body. When the container is in a static state, the liquid phase-change medium is located at the bottom of the separator, ensuring that the separator effectively isolates the second container body from the phase change liquid.

[0019] In addition, there is a flow gap between the isolation piece and the inner wall of the first container body; when the user shakes the container, the liquid phase change medium under the isolation piece can flow through the flow gap and contact the second container body to vaporize, and the vapor phase change medium contacts the first container body to liquefy, and the above-mentioned vaporization and liquefaction continue, thereby reducing the low temperature of the liquid in the second container body and achieving the hand-warming effect of the container.

[0020] In any of the above technical solutions, the sealing medium is a solid medium, the solid medium is arranged at the bottom of the second container body, or the density of the solid medium is less than the density of the liquid phase change medium, and an overflow port is provided on the solid medium.

[0021] In this technical solution, the enclosed medium is a solid medium with an overflow port provided therein. The solid medium can be directly disposed at the bottom of the second container body, thereby isolating the second container body from the liquid phase-change medium through the fixed solid medium. Alternatively, the solid medium can be made less dense than the liquid phase-change medium, allowing the solid medium to float above the liquid phase-change medium, thereby isolating the second container body from the liquid phase-change medium through the floating solid medium.

[0022] Specifically, when the user shakes the container, the liquid phase change medium under the isolation piece can flow through the flow port of the solid medium and contact the second container body to vaporize, and the vapor phase change medium contacts the first container body to liquefy, and the above-mentioned vaporization and liquefaction continue, thereby reducing the low temperature of the liquid in the second container body and achieving the hand-warming effect of the container.

[0023] In any of the above technical solutions, the thermal conductivity of the solid medium is less than or equal to 0.81 W / (mK).

[0024] In this technical solution, to ensure good thermal insulation of the enclosed medium, the thermal conductivity of the solid medium is designed to be less than or equal to 0.81 W / (mK). This way, when the container is stationary, the isolation medium provides excellent thermal insulation between the second container body and the liquid phase-change medium, preventing heat from transferring from the second container body to the liquid phase-change medium. This also ensures that, without the user shaking the container, the phase-change medium will not lower the temperature of the liquid or food inside the second container body through a phase change reaction, thus achieving controllable cooling.

[0025] In any of the above technical solutions, the sealing medium is a liquid medium, the liquid medium is immiscible with the liquid phase change medium, and the density of the liquid medium is lower than the density of the liquid phase change medium.

[0026] In this technical solution, the enclosed medium is a liquid medium. The liquid medium is immiscible with the liquid phase-change medium, thereby ensuring that the enclosed medium and the liquid phase-change medium exist in layers. Furthermore, the density of the liquid medium is lower than that of the liquid phase-change medium, ensuring that the enclosed medium is located on top of the phase-change medium. The enclosed medium thereby isolates the second container body from the liquid phase-change medium.

[0027] Specifically, when the container is stationary, the enclosed medium and the liquid phase-change medium exist as separate layers, with the enclosed medium located between the liquid phase-change medium and the second container body, providing isolation. When the user shakes the container, the liquid phase-change medium at the bottom breaks through the enclosed medium at the top and comes into contact with the second container body, vaporizing. The vaporized phase-change medium then liquefies upon contact with the first container body. This continuous vaporization and liquefaction process lowers the temperature of the liquid in the second container body and provides the container's hand-warming effect.

[0028] In any of the above technical solutions, the boiling point of the liquid medium is higher than the boiling point of the liquid phase change medium.

[0029] In this technical solution, the boiling point of the liquid medium is higher than that of the liquid phase-change medium. This ensures that the boiling point of the enclosed medium is higher than that of the liquid phase-change medium. This ensures that when the user shakes the container and the liquid phase-change medium vaporizes within the phase-change chamber, the vaporized phase-change medium does not cause the enclosed medium to vaporize as well. This ensures that the enclosed medium remains stable within the phase-change chamber and, when the container is once again at rest, the enclosed medium can still isolate the liquid phase-change medium from the second container body.

[0030] In any of the above technical solutions, the phase change chamber is located on the circumference and bottom of the second container body; when the container is in a static state, the liquid phase change medium is located at the bottom of the second container body, and there is a gap between it and the outer bottom wall of the second container body, and the closed medium is at least located within the gap.

[0031] In this technical solution, a phase change chamber is formed on the circumferential side and bottom of the second container body; in a static state, the liquid phase change medium is located at the bottom of the second container body, and there is a gap between the liquid phase change medium and the outer bottom wall of the second container body, and the closed medium is at least located in the gap to achieve an isolation effect or.

[0032] When the user shakes the container, the liquid phase change medium flows to the side of the second container body and contacts the second container body. At this time, vaporization and liquefaction can occur on the side of the second container body, while lowering the temperature of the hot water in the second container body. The contact area between the liquid phase change medium and the second container body is increased to further intensify the intensity of vaporization. At the same time, the gaseous phase change medium is ensured to contact the side wall of the first container body, ensuring the temperature of the part held by the user, thereby achieving the effect of warming the hands.

[0033] In any of the above technical solutions, the ratio of the volume of the liquid phase change medium to the volume of the phase change chamber is greater than or equal to 35% and less than or equal to 45%.

[0034] In this technical solution, the amount of phase-change medium directly affects the intensity of the gas-liquid phase transition, and thus the heat transfer capacity of the phase-change material. This invention ensures that the ratio of the volume of the liquid phase-change medium to the volume of the phase-change chamber is greater than or equal to 35% and less than or equal to 45%. Properly designing the amount of phase-change medium ensures a cooling effect on the hot water in the second container while preventing the first container from becoming too hot due to excessive heat exchange.

[0035] Specifically, the optimal hand-warming temperature range is 45°C to 55°C. Overheating the first container body can easily burn hands, while overcooling the first container body will not be effective enough. Ensuring that the ratio of the volume of the liquid phase-change medium to the volume of the phase-change chamber is greater than or equal to 35% and less than or equal to 45% effectively keeps the first container body within the 45°C to 55°C temperature range, achieving optimal heat exchange and hand-warming results.

[0036] In any of the above technical solutions, the boiling point of the liquid phase change medium is greater than or equal to 40°C and less than or equal to 60°C.

[0037] In this technical solution, the boiling point of the liquid phase-change medium determines the temperature of the hot water in the second container after heat exchange, indirectly determining the heat exchange efficiency of the hot water in the second container. Generally, warm water between 40°C and 60°C is most suitable for human consumption. Because the present invention uses a phase-change medium with a boiling point greater than or equal to 40°C and less than or equal to 60°C for heat exchange, the temperature of the hot water in the second container after heat exchange is effectively guaranteed, ensuring that the hot water is suitable for direct drinking by the user.

[0038] In any of the above technical solutions, when the container is in a static state, the liquid level of the partially enclosed medium located on the peripheral side of the second container body is higher than or flush with the outer bottom wall of the second container body.

[0039] In this technical solution, the sealing medium exists both below and to the sides of the second container body. Furthermore, when the container is in a static state, the liquid level of the portion of the sealing medium located around the second container body is higher than or flush with the outer bottom wall of the second container body. This ensures that the portion of the sealing medium located below the second container body abuts the outer bottom wall of the second container body, while also ensuring that the sealing medium located to the sides of the second container body can also block the phase change medium.

[0040] In any of the above technical solutions, the ratio of the total volume of the liquid phase change medium and the sealing medium to the volume of the phase change chamber is greater than or equal to 40% and less than or equal to 50%.

[0041] In this technical solution, the combined volume of the liquid phase-change medium and the enclosing medium directly influences the intensity of the gas-liquid phase transition, and thus the heat exchange capacity of the phase-change material. This invention ensures that the ratio of the combined volume of the liquid phase-change medium and the enclosing medium to the volume of the phase-change chamber is greater than or equal to 40% and less than or equal to 50%. By rationally designing the amount of phase-change medium and the enclosing medium, it ensures a cooling effect on the hot water in the second container body while preventing the first container body from becoming too hot due to excessive heat exchange.

[0042] Specifically, the optimal hand-warming temperature range is 45°C to 55°C. Overheating the first container body can easily burn your hands, while overcooling the first container body will not be effective enough. Properly designing the combined volume of the phase-change medium and the enclosed medium can effectively ensure that the first container body remains within the 45°C to 55°C temperature range, achieving optimal heat exchange and hand-warming results.

[0043] In any of the above technical solutions, the first container body is a heat-conducting body.

[0044] In this technical solution, the first container body is a heat-conducting body to ensure that the heat generated when the phase change medium is liquefied can be quickly transferred to the first container body, so as to quickly increase the temperature of the first container body and achieve the effect of quickly warming the hands.

[0045] In any of the above technical solutions, the second container body is a heat-conducting body.

[0046] In this technical solution, the second container body is a heat-conducting body to ensure that the heat of the hot water inside the second container body can be quickly transferred to the second container body, so that the phase change medium is vaporized.

[0047] Specifically, the first container body and the second container body may be metal container bodies.

[0048] In any of the above technical solutions, the outer side wall of the second container body is provided with a vaporization surface.

[0049] In this technical solution, the outer side wall of the second container body is provided with a vaporization surface, so that the phase change medium can be vaporized when in contact with the vaporization surface to absorb the second container body.

[0050] In any of the above technical solutions, a liquefied surface is provided on the inner side wall of the first container body.

[0051] In this technical solution, the inner side wall of the first container body is provided with a liquefaction surface, so that the phase change medium can be liquefied when it contacts the liquefaction surface, thereby releasing heat to the first container body.

[0052] In any of the above technical solutions, the inner side wall of the first container body is provided with a guide surface, and the liquid phase change medium flows back from the guide surface to the bottom of the phase change chamber.

[0053] In this technical solution, the inner sidewall of the first container body is provided with a flow-guiding surface. This flow-guiding surface extends to the bottom of the phase-change chamber. Thus, when the gaseous phase-change medium contacts the inner sidewall of the first container body and condenses into liquid, the liquid phase-change medium flows back from the flow-guiding surface to the bottom of the phase-change chamber, enabling the phase-change medium to be recovered and reused.

[0054] In any of the above technical solutions, the phase change chamber is a sealed interlayer, and the first container body and the second container body form a sealed interlayer.

[0055] In this technical solution, the phase change chamber is a sealed interlayer, and the sealed interlayer is directly defined and formed by the first container body and the second container body, which can greatly simplify the structure of the container and facilitate processing and manufacturing.

[0056] In any of the above technical solutions, a receiving chamber is provided in the second container body, and the phase change medium is located on the circumference and bottom of the receiving chamber.

[0057] In this technical solution, a accommodating chamber is provided in the second container body, which can be used to place hot water, etc.; the phase change medium is located on the side and bottom of the accommodating chamber to ensure that the phase change medium can fully contact and exchange heat with the second container body.

[0058] In any of the above technical solutions, the container further includes a cover, which can be covered on the first container body or the second container body.

[0059] In this technical solution, the container further comprises a cover, which can be arranged on the first container body or the second container body to prevent dust from falling into the receiving chamber of the second container body and to prevent heat loss in the receiving chamber.

[0060] Specifically, the container proposed by the present invention can be a water cup.

[0061] Additional aspects and advantages of the invention will become apparent from the description which follows, or may be learned by practice of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments with reference to the accompanying drawings, in which:

[0063] Figure 1 It is a structural schematic diagram of a container according to an embodiment of the present invention;

[0064] Figure 2 yes Figure 1 A partial enlarged view of point A of the container shown.

[0065] in, Figure 1 and Figure 2 The corresponding relationship between the reference numerals and component names is as follows:

[0066] 102 first container body, 104 second container body, 106 phase change chamber, 108 phase change medium, 110 sealing medium, 112 vaporization surface, 114 liquefaction surface, 116 containing chamber, 118 cover. DETAILED DESCRIPTION

[0067] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0069] Refer to the following Figure 1 and Figure 2 Containers provided according to some embodiments of the present invention are described below.

[0070] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention proposes a container, including: a first container body 102, a second container body 104, a phase change chamber 106, a phase change medium 108 and a sealing medium 110; the phase change medium 108 is a gas-liquid phase change medium, and the phase change medium 108 is liquid at room temperature.

[0071] Among them, Figure 1 and Figure 2 As shown, the second container body 104 is disposed within the first container body 102. The interior of the second container body 104 can be used to store hot water, etc. A phase change chamber 106 is located between the first container body 102 and the second container body 104. A phase change medium 108 and a sealing medium 110 are disposed within the phase change chamber 106. When the container is in a static state, the phase change medium 108 is located at the bottom of the phase change chamber 106, and the sealing medium 110 is separated between the liquid phase change medium 108 and the second container body 104.

[0072] When the user shakes the container, the phase change medium 108 flows in the phase change chamber 106 and contacts the second container body 104. The liquid phase change medium 108 absorbs heat from the second container body 104 and vaporizes into gas. Correspondingly, the gaseous phase change medium 108 contacts the first container body 102 and can release heat and liquefy into liquid. This cycle is repeated to cool the hot water in the second container body 104 and realize the hand warming function of the container.

[0073] In particular, since the phase change medium 108 is a gas-liquid phase change medium and can vaporize and liquefy, this ensures that the gas-liquid phase change of the phase change medium 108 is intense and rapid, and its efficiency far exceeds the heat conduction of ordinary solids or liquids. This allows the phase change medium 108 to absorb a large amount of heat when vaporizing and release a large amount of heat when liquefying, greatly improving the heat exchange effect, increasing the cooling rate of the hot water in the second container body 104 and the heating rate of the first container body 102. At the same time, the phase change medium 108 can be fully recycled, which is more environmentally friendly and economical.

[0074] And, as Figure 1 and Figure 2 As shown, when the container is in a static state, the sealing medium 110 can isolate the liquid phase change medium 108 from the second container body 104. In this way, on the basis of ensuring that the liquid surface of the liquid phase change medium 108 does not contact the second container body 104, the liquid phase change medium 108 is further isolated from the second container body 104 by the sealing medium 110, thereby preventing the liquid phase change medium 108 from contacting and exchanging heat with the second container body 104, further improving the controllability of the temperature reduction.

[0075] It should be noted here that the above-mentioned working state means that the user places a liquid or food with a higher temperature in the second container body 104, and the temperature of the liquid or food may need to be lowered through the phase change medium 108; when the container is in the working state, the user needs to shake the container so that the container breaks through the sealing medium 110 and contacts the second container body 104, and the phase change medium 108 continuously undergoes a phase change reaction.

[0076] Correspondingly, the above-mentioned static state means that the container is in a stable state, and the phase change medium 108 is separated from the second container body 104, and the sealing medium 110 is isolated between the phase change medium 108 and the second container body 104. At this time, the phase change medium 108 is liquid and does not undergo phase change reaction.

[0077] In addition, the present invention is explained only by taking hot water in the second container body 104 as an example, but the actual application is not limited to hot water, which is understandable to those skilled in the art.

[0078] Therefore, the container proposed in the present invention fully utilizes the gas-liquid phase change of the phase change medium 108, can instantly absorb and release a large amount of heat, accelerate the rate of the entire heat conduction, and greatly improve the heat exchange efficiency of the container; and can improve the controllability of the phase change reaction through the closed medium 110, on the one hand, ensuring the temperature of the liquid or food after cooling, and on the other hand, preventing the user from accidentally touching the container and causing the phase change reaction of the phase change medium 108.

[0079] In some embodiments, the phase change medium 108 may be methylene chloride, ethanol, or the like; and the sealing medium 110 may be water, honeycomb ceramics, wick ceramics, aerogel film, or the like.

[0080] like Figure 1 and Figure 2 As shown, the second embodiment of the present invention provides a container, which further comprises:

[0081] There is only a fixed amount of phase change medium 108 in the phase change chamber 106, and it is ensured that when the container is in a static state, the liquid level of the liquid phase change medium 108 is lower than the outer bottom wall of the second container body 104, so that there is a gap between the liquid level of the liquid phase change medium 108 and the outer bottom wall of the second container body 104.

[0082] Thus, when the container is stationary, the liquid phase-change medium 108 is separated from the second container body 104. Even if hot water is present in the second container body 104, the phase-change medium 108 will not vaporize, thus achieving controllable cooling. Specifically, when the user needs to lower the temperature of the hot water in the second container body 104 using the phase-change medium 108, they simply shake the container to bring the liquid phase-change medium 108 into contact with the second container body 104.

[0083] like Figure 1 and Figure 2 As shown, the third embodiment of the present invention provides a container, which further comprises:

[0084] The container also includes a separator (not shown), which serves as a sealing medium 110. Specifically, the separator is disposed at the bottom of the second container body 104; when the container is in a static state, the liquid phase change medium 108 is located at the bottom of the separator, ensuring that the separator effectively isolates the second container body 104 from the liquid phase change medium.

[0085] In addition, there is a flow gap between the isolation piece and the inner wall of the first container body 102; when the user shakes the container, the liquid phase change medium 108 under the isolation piece can flow through the flow gap and contact the second container body 104 to vaporize, and the vaporous phase change medium 108 contacts the first container body 102 to liquefy, and the above-mentioned vaporization and liquefaction continue, thereby reducing the low temperature of the liquid in the second container body 104 and achieving the hand-warming effect of the container.

[0086] In a specific embodiment, the sealing medium 110 can be made of honeycomb ceramics, wick ceramics, etc.

[0087] like Figure 1 and Figure 2As shown, the fourth embodiment of the present invention provides a container, which further comprises:

[0088] The sealing medium 110 is a solid medium with an overflow port. The solid medium can be placed directly on the bottom of the second container body 104 to isolate the second container body 104 from the liquid phase-change medium 108. Alternatively, the solid medium can be placed with a density less than that of the liquid phase-change medium 108 to float above the liquid phase-change medium 108. This allows the floating solid medium to isolate the second container body 104 from the liquid phase-change medium 108.

[0089] Specifically, when the user shakes the container, the liquid phase change medium 108 under the isolation piece can flow through the flow port of the solid medium and contact the second container body 104 to vaporize, and the vapor phase change medium 108 contacts the first container body 102 to liquefy, and the above-mentioned vaporization and liquefaction continue, thereby reducing the low temperature of the liquid in the second container body 104 and achieving the hand-warming effect of the container.

[0090] In a specific embodiment, the solid medium may be a honeycomb medium having multiple pores and low thermal conductivity.

[0091] In this embodiment, to ensure good thermal insulation of the enclosed medium 110, the thermal conductivity of the solid medium is designed to be less than or equal to 0.81 W / (mK). Thus, when the container is in a static state, the isolation medium provides good thermal insulation between the second container body 104 and the liquid phase-change medium 108, ensuring that heat within the second container body 104 is not transferred to the liquid phase-change medium 108. This also ensures that, if the user does not shake the container, the phase-change medium 108 does not lower the temperature of the liquid or food within the second container body 104 through a phase change reaction, thereby achieving controllable cooling.

[0092] In a specific embodiment, the thermal conductivity of the solid medium can be 0.10W / (mK), 0.20W / (mK), 0.30W / (mK), 0.40W / (mK), 0.50W / (mK), 0.60W / (mK), 0.70W / (mK), 0.80W / (mK), 0.81W / (mK), etc., and those skilled in the art can design it according to actual needs.

[0093] In a specific embodiment, the sealing medium 110 can be made of honeycomb ceramics, wick ceramics, aerogel film, etc.

[0094] like Figure 1 and Figure 2 As shown, the fifth embodiment of the present invention provides a container, which further comprises:

[0095] like Figure 1 and Figure 2 As shown, the sealing medium 110 is a liquid medium. The liquid medium is immiscible with the liquid phase-change medium 108, thereby ensuring that the sealing medium 110 and the liquid phase-change medium 108 exist in layers. The density of the liquid medium is also lower than that of the liquid phase-change medium 108, ensuring that the sealing medium 110 is located on top of the phase-change medium 108. The sealing medium 110 thus achieves the function of isolating the second container body 104 from the liquid phase-change medium 108.

[0096] Specifically, when the container is stationary, the sealing medium 110 and the liquid phase-change medium 108 are separated by layers, and the sealing medium 110 is located between the liquid phase-change medium 108 and the second container body 104, providing isolation. When the user shakes the container, the liquid phase-change medium 108 at the bottom breaks through the sealing medium 110 at the top and comes into contact with the second container body 104, vaporizing. The vaporized phase-change medium 108 then comes into contact with the first container body 102, liquefying. This continuous vaporization and liquefaction process lowers the temperature of the liquid in the second container body 104 and provides the container's hand-warming effect.

[0097] In a specific embodiment, the sealing medium 110 is incompatible with the liquid phase-change medium 108, meaning that the sealing medium 110 does not physically or chemically react with the phase-change medium 108, thereby exhibiting excellent chemical incompatibility. Furthermore, the sealing medium 110 also must not physically or chemically react with the first container body 102 and the second container body 104, thereby exhibiting excellent chemical incompatibility.

[0098] In this embodiment, the boiling point of the liquid medium is further higher than that of the liquid phase-change medium 108. In other words, the boiling point of the enclosed medium 110 is ensured to be higher than that of the liquid phase-change medium 108. Thus, when the user shakes the container and the liquid phase-change medium 108 vaporizes within the phase-change chamber 106, the vaporous phase-change medium 108 does not cause the enclosed medium 110 to vaporize. This ensures that the enclosed medium 110 remains stable within the phase-change chamber 106 and that, when the container is again placed in a static state, the enclosed medium 110 can still function to isolate the liquid phase-change medium 108 from the second container body 104.

[0099] In this embodiment, further, Figure 2As shown, the amount of phase change medium 108 directly affects the intensity of the gas-liquid phase transition, and thus the heat exchange capacity of the phase change medium 108. This embodiment ensures that the ratio of the volume of the liquid phase change medium 108 to the volume of the phase change chamber 106 is greater than or equal to 35% and less than or equal to 45%. Properly designing the amount of phase change medium 108 ensures a cooling effect on the hot water in the second container body 104 while preventing the first container body 102 from becoming too hot due to excessive heat exchange.

[0100] Specifically, the optimal hand-warming temperature range is 45°C to 55°C. If the first container body 102 is overheated, it can easily burn your hands, while if it is too cold, the hand-warming effect is insufficient. Ensuring that the ratio of the volume of the liquid phase-change medium 108 to the volume of the phase-change chamber 106 is greater than or equal to 35% and less than or equal to 45% effectively maintains the first container body 102 within the temperature range of 45°C to 55°C, achieving optimal heat exchange and hand-warming effects.

[0101] In this embodiment, the boiling point of the liquid phase-change medium 108 further determines the temperature of the hot water in the second container body 104 after heat exchange, which indirectly determines the heat exchange efficiency of the hot water in the second container body 104. Generally, warm water between 40°C and 60°C is most suitable for human consumption. Because this embodiment uses a phase-change medium 108 with a boiling point greater than or equal to 40°C and less than or equal to 60°C for heat exchange, the temperature of the hot water in the second container body 104 after heat exchange is effectively guaranteed, ensuring that the hot water after heat exchange is suitable for direct drinking by the user.

[0102] In a specific embodiment, the ratio of the volume of the liquid phase change medium 108 to the volume of the phase change chamber 106 can be 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, etc., and those skilled in the art can design it according to actual needs.

[0103] In this embodiment, further, Figure 1 and Figure 2 As shown, the total volume of the liquid phase change medium 108 and the enclosed medium 110 directly affects the intensity of the gas-liquid phase transition, and thus the heat exchange capacity of the phase change medium 108. This embodiment ensures that the ratio of the total volume of the liquid phase change medium 108 and the enclosed medium 110 to the volume of the phase change chamber 106 is greater than or equal to 40% and less than or equal to 50%. Reasonable design of the amount of phase change medium 108 and the enclosed medium 110 ensures a cooling effect on the hot water in the second container body 104 while preventing the first container body 102 from becoming too hot due to excessive heat exchange.

[0104] Specifically, the optimal hand-warming temperature range is 45°C to 55°C. If the first container body 102 is overheated, it can easily burn your hands, while if it is too cold, the hand-warming effect is insufficient. However, in this embodiment, the combined volume of the phase-change medium 108 and the sealing medium 110 is rationally designed to effectively ensure that the first container body 102 remains within the temperature range of 45°C to 55°C, achieving the optimal heat exchange and hand-warming effect.

[0105] In a specific embodiment, the ratio of the total volume of the liquid phase change medium 108 and the sealing medium 110 to the volume of the phase change chamber 106 can be 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, etc., and those skilled in the art can design it according to actual needs.

[0106] On the basis of the first to fifth embodiments, preferably, Figure 1 and Figure 2 As shown, the first container body 102 is a heat-conducting body to ensure that the heat generated when the phase change medium 108 is liquefied can be quickly transferred to the first container body 102 to quickly increase the temperature of the first container body 102 and achieve a quick hand warming effect.

[0107] On the basis of the first to fifth embodiments, preferably, Figure 1 and Figure 2 As shown, the second container body 104 is a heat-conducting body to ensure that the heat of the hot water inside the second container body 104 can be quickly transferred to the second container body 104 , so that the phase change medium 108 is vaporized.

[0108] In a specific embodiment, the first container body 102 and the second container body 104 can be metal container bodies.

[0109] On the basis of the first to fifth embodiments, preferably, Figure 1 and Figure 2 As shown, the outer side wall of the second container body 104 is provided with a vaporization surface 112 , so that the phase change medium 108 can be vaporized when in contact with the vaporization surface 112 to absorb the second container body 104 .

[0110] In a specific embodiment, the outer wall of the second container body 104 can be directly used as the vaporization surface 112 .

[0111] On the basis of the first to fifth embodiments, further, as Figure 1 As shown, the inner sidewall of the first container body 102 is provided with a liquefaction surface 114 , so that the phase change medium 108 can be liquefied when in contact with the liquefaction surface 114 to release heat to the first container body 102 .

[0112] In a specific embodiment, the inner wall of the first container body 102 can be directly used as the liquefaction surface 114 .

[0113] On the basis of the first to fifth embodiments, preferably, Figure 1 As shown, the inner sidewall of the first container body 102 is provided with a guide surface. The guide surface extends to the bottom of the phase change chamber 106. Thus, when the gaseous phase change medium 108 contacts the inner sidewall of the first container body 102 and condenses into liquid, the liquid phase change medium 108 flows back from the guide surface to the bottom of the phase change chamber 106, thereby enabling the phase change medium 108 to be recovered and reused.

[0114] In a specific embodiment, the inner sidewall of the first container body 102 can be directly used as a flow guide surface.

[0115] On the basis of the first to fifth embodiments, preferably, Figure 1 As shown, the phase change chamber 106 is a sealed interlayer, and the sealed interlayer is directly defined and formed by the first container body 102 and the second container body 104, which can greatly simplify the structure of the container and facilitate processing and manufacturing.

[0116] On the basis of the first to fifth embodiments, further, as Figure 1 As shown, a accommodating chamber 116 is provided in the second container body 104, and the accommodating chamber 116 can be used to place hot water, etc.; the phase change medium 108 is located on the side and bottom of the accommodating chamber 116 to ensure that the phase change medium 108 can fully contact and exchange heat with the second container body 104.

[0117] On the basis of the first to fifth embodiments, preferably, Figure 1 As shown, the container further includes a cover 118, which can be provided on the first container body 102 or the second container body 104. On the one hand, the cover 118 prevents dust from falling into the receiving chamber 116 of the second container body 104, and on the other hand, it prevents heat loss in the receiving chamber 116.

[0118] In a specific embodiment, the container provided by the present invention may be a water cup.

[0119] like Figure 1 and Figure 2 As shown, a specific embodiment of the present invention proposes a container that achieves efficient heat exchange through phase change technology, wherein the container includes a cover 118, a first container body 102 and a second container body 104, the first container body 102 is arranged on the outside of the second container body 104, and forms a phase change chamber 106 with the second container body 104, and the phase change chamber 106 has a liquid medium in it, and the liquid medium is used to transfer the heat of the second container body 104 to the first container body 102.

[0120] When hot water is poured into the second container body 104, the liquid medium quickly transfers the heat from the second container body 104 to the first container body 102, cooling the hot water in the second container body 104. The first container body 102 then provides functions such as heating and hand warming. The structure is very simple, the heat exchange rate is fast, and the cost is low. The liquid medium can be a phase change medium 108, or a combination of a phase change medium 108 and a sealing medium 110.

[0121] In a specific embodiment, Figure 1 and Figure 2 As shown, the present invention provides a highly efficient heat exchange container that can quickly and effectively reduce the temperature of boiling water in the second container body 104 while simultaneously generating heat in the first container body 102 for hand warming and other functions, with a more convenient structure. The container includes a lid 118, a first container body 102, and a second container body 104. The first container body 102 is sleeved onto the outside of the second container body 104 and, together with the second container body 104, forms a phase change chamber 106 containing a liquid medium; the liquid medium includes a phase change medium 108 and a sealing medium 110.

[0122] Preferably, phase change medium 108 transfers heat through a gas-liquid phase transition. Enclosed medium 110 inhibits operation of phase change medium 108 when heat transfer is not required, ensuring controllable phase change heat transfer. The boiling point of phase change medium 108 is generally between 40°C and 60°C, and the density of enclosed medium 110 is less than that of phase change medium 108.

[0123] Preferably, when the container is at rest, Figure 1 and Figure 2 As shown, the liquid medium is located at the bottom of the phase change chamber 106 and abuts against the outer bottom wall of the second container body 104. The sealing medium 110 is located between the phase change medium 108 and the outer bottom wall of the second container body 104 to ensure that the phase change medium 108 does not work.

[0124] Specifically, the boiling point of phase change medium 108 is generally between 40°C and 60°C, and the total volume of the liquid medium accounts for 2 / 5 to 1 / 2 of the total volume of phase change chamber 106. The specific space ratio can be selected based on actual conditions. Preferably, the optimal hand warming temperature range should be between 45°C and 55°C. Too hot will easily burn the hands, while too cold will not be effective enough.

[0125] In a specific embodiment, the boiling point of the phase change medium 108 can be 40° C., 42° C., 45° C., 48° C., 50° C., 52° C., 55° C., 58° C., 60° C., etc., and those skilled in the art can design it according to actual conditions.

[0126] In a specific embodiment, Figure 1 and Figure 2As shown, taking the second container body 104 filled with 100°C boiling water as an example, after shaking the container for 5 to 10 seconds, 3 to 5 temperature measurement points are evenly distributed from top to bottom in the first container, and the average temperature of these temperature measurement points is used as the test temperature. (Specifically, the container does not need to be inverted; it only needs to be naturally swung left and right to ensure that the phase change medium 108 in the phase change chamber 106 can contact the bottom of the second container body 104. The number of shaking times is selected to be 3 to 5.) The cooling and heat transfer effects are shown in Table 1.

[0127] Therefore, in the present application, when the ratio of the volume of the sealed medium 110 to the volume of the phase change chamber 106 is 5%, the ratio of the volume of the liquid phase change medium 108 to the volume of the phase change chamber 106 is selected to be greater than or equal to 35% and less than or equal to 45%, so as to ensure that the side wall temperature of the first container body 102 is between 45°C and 55°C after heat exchange, so as to ensure the optimal hand-warming temperature.

[0128] Specifically, the "phase change medium ratio" in Table 1 is the ratio of the volume of the liquid phase change medium 108 to the volume of the phase change chamber 106, the "closed medium ratio" is the ratio of the volume of the closed medium 110 to the volume of the phase change chamber 106, and the "liquid medium ratio" is the ratio of the total volume of the liquid phase change medium 108 and the closed medium 110 to the volume of the phase change chamber 106.

[0129] Table 1

[0130]

[0131] When the user uses the container, boiling water is poured into the second container body 104 and the container is shaken. The phase change medium 108 in the phase change chamber 106 contacts the second container body 104 to break through the closed medium 110. Since the boiling point of the liquid phase change medium 108 is lower than the temperature of the outer wall of the second container body 104, the liquid phase change medium 108 will vaporize to form a gaseous medium; when the gaseous phase change medium 108 encounters the low temperature area inside the first container body 102, it will release heat and condense into a liquid medium, thereby transferring the heat of the second container body 104 to the first container body 102, realizing the process of cooling the second container body 104 and heating the first container body 102. The condensed liquid medium slides down the inner wall of the first container body 102 and settles to the bottom of the phase change chamber 106. Since the density of the sealing medium 110 is less than that of the phase change medium 108 and the two are immiscible, the sealing medium 110 will gradually form a sealing layer above the phase change medium 108, again blocking the connection between the phase change medium 108 and the second container body 104, and isolating the phase change process from occurring.

[0132] When the user uses the container next time, they continue to shake the container, repeating the cycle to fully exchange the heat between the second container body 104 and the first container body 102. The entire heat exchange process utilizes the phase change process of the gas-liquid phase change medium, which can instantly absorb and release a large amount of heat energy. This accelerates the rate of heat conduction and greatly improves heat exchange efficiency.

[0133] Therefore, the phase change medium 108 filled in the phase change chamber 106 of the container proposed by the present invention is a gas-liquid phase change medium, the heat exchange process is uniform and efficient, the selected heat exchange method is safe and pollution-free, the selected phase change medium 108 is widely available and relatively low in price, and can quickly and effectively reduce the temperature of the boiling water in the first container body 102, while making the second container body 104 heat up and have functions such as warming hands, and the structure is more convenient.
