Description

Technical Field

[0001] The present invention relates to the technical field of thawing, 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 phase change to lower the liquid position, but the phase change process is uncontrollable, which directly leads to the liquid temperature after cooling being too high or too low, and cannot meet user 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 heat exchange chamber, located between the first container body and the second container body, at least partially located at the bottom of the second container body; a vapor-liquid phase change medium, arranged in the heat exchange chamber; wherein the bottom wall of the second container body is provided with a first position and a second position, the first position is lower than the second position, and when the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium is located at the first position.

[0008] The container proposed in the present invention includes a first container body, a second container body, a heat exchange chamber, and a vapor-liquid phase change medium. 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 heat exchange chamber is located between the first and second container bodies and contains the vapor-liquid phase change medium.

[0009] The bottom wall of the second container body is provided with a first position and a second position, wherein the first position is lower than the second position. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium is located at the first position, such that the liquid vapor-liquid phase change medium is in contact with the first position and the liquid vapor-liquid phase change medium is separated from the second position.

[0010] In particular, by optimizing the bottom wall of the second container body, the strength and hardness of the second container body can be improved, which helps to extend the service life of the second container body. Furthermore, because the bottom wall of the second container body has first and second positions with different heights, the space of the heat exchange chamber can be adjusted, achieving adjustable filling volume of the vapor-liquid phase change medium and greater flexibility.

[0011] Specifically, during use, the user can place high-temperature food or liquid in the second container body. By shaking the container, the contact area between the vapor-liquid phase change medium and the second container body can be changed, thereby adjusting the heat transfer efficiency of the vapor-liquid phase change medium and achieving controllable cooling. After the user shakes the container, the container is in operation, and the vapor-liquid phase change medium contacts a large area of ​​the second container body. Due to the high-temperature food or liquid placed in the second container body, the temperature of the second container body is higher, while the temperature of the first container body is relatively lower, generally equal to room temperature. Therefore, after the vapor-liquid phase change medium contacts the second container body, it absorbs heat from the second container body and undergoes a vaporization reaction to become a gaseous medium. The gaseous medium transfers heat to the first container body and undergoes a liquefaction reaction to become a liquid medium, thereby cooling the food or liquid in the second container body. At the same time, the heat released by the heat transfer medium to the first container body increases the temperature of the first container body, thereby achieving the container's hand-warming function.

[0012] Specifically, when the container is in a static state, a first location on the bottom wall of the second container body contacts the liquid vapor-liquid phase change medium, and only this first location contacts the liquid vapor-liquid phase change medium. At this point, a small amount of heat from the second container body is transferred to the liquid vapor-liquid phase change medium, raising the temperature of the entire bottom of the container. This allows the user to sense the temperature of the food or liquid in the second container body by the temperature at the bottom of the container. Furthermore, it also indicates to the user that the food or liquid in the second container body is too hot, prompting the user to shake the container to cool it down.

[0013] In addition, if the temperature at the bottom of the container does not rise significantly or is consistent with the room temperature, it means that the temperature of the food or liquid in the second container body is appropriate. At this time, the user can determine that there is no need to shake the container to cool the food or liquid in the second container body.

[0014] Moreover, when the container is in a stationary state, only a small portion of the liquid vapor-liquid phase change medium is in contact with the second container body, ensuring less heat exchange between the vapor-liquid phase change medium and the food or liquid in the second container body, which can slow down the heat loss of the food or liquid in the second container body, so that the container has a certain heat preservation effect without the user shaking the container.

[0015] In addition, the bottom wall of the second container body is designed to have different heights. When the user shakes the container, the shaking force can be adjusted to control the contact between the liquid vapor-liquid phase change medium and the bottom wall of the second container body at different heights, or the contact between the liquid vapor-liquid phase change medium and the side wall of the second container body can be controlled to adjust the contact area between the liquid vapor-liquid phase change medium and the second container body, thereby improving the controllability of heat exchange between the vapor-liquid phase change medium and the second container body, making it easier for users to use in daily life.

[0016] Moreover, the vapor-liquid phase change is drastic and rapid, which can absorb and release a large amount of heat instantly. The heat transfer efficiency far exceeds the heat conduction of ordinary solids or liquids, so that the vapor-liquid 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 transfer effect, increases the cooling rate of the food or liquid in the second container body, and the heating rate of the first container body. At the same time, the vapor-liquid phase change medium can be fully recycled, which is more environmentally friendly and economical.

[0017] Therefore, the container proposed in the present invention makes full use of the vapor-liquid phase change of the vapor-liquid phase change medium, can instantly absorb and release a large amount of heat, accelerates the rate of the entire heat conduction, greatly improves the heat exchange efficiency of the container, and at the same time realizes the controllability of heat exchange; and, by optimizing the shape of the bottom wall of the second container body, the strength and hardness of the second container body are improved, so that the space of the heat exchange chamber is adjustable, and the filling volume of the vapor-liquid phase change medium is adjustable, which is more flexible.

[0018] The container according to the above technical solution of the present invention may also have the following additional technical features:

[0019] In the above technical solution, the bottom wall of the second container body is provided with a first wall surface, which is inclined relative to the horizontal plane; the first position and the second position are at least located at different heights of the first wall surface.

[0020] In this technical solution, the bottom wall of the second container body is provided with a first wall surface. The first wall surface is inclined relative to a horizontal plane to ensure that the first bottom wall is an inclined wall surface. The first position and the second position are at least located at different heights of the first wall surface to ensure that the first position and the second position are at different heights. Specifically, the first position and the second position can be located at opposite ends of the first wall surface to ensure a sufficient height difference between the first position and the second position.

[0021] That is, in this technical solution, the bottom wall of the second container body includes an inclined surface (i.e., an inclined first wall), and the relatively lower end of the inclined surface is used as the first position, and the higher end of the inclined surface is used as the second position. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium is in the first position, so that the liquid vapor-liquid phase change medium is exactly at the lower end of the inclined surface, ensuring that only a small portion of the liquid vapor-liquid phase change medium is in contact with the second container body when the container is in a static state, so that a small amount of heat is exchanged between the food or liquid in the second container body and the vapor-liquid phase change medium, so that the user can sense whether to shake the container by the temperature at the bottom of the container to cool the food or liquid in the second container body. In addition, when the user shakes the container to cool the food or liquid in the second container body, the degree of cooling can be controlled by the shaking force, thereby achieving controllability of whether to cool and the degree of cooling.

[0022] In any of the above technical solutions, the bottom wall of the second container body is also provided with a connected second wall surface, the second wall surface is connected to the first wall surface, and the second wall surface is inclined compared to the horizontal plane; one of the first position and the second position is located at the connection between the first wall surface and the second wall surface, and the other of the first position and the second position is located on the first wall surface and / or the second wall surface.

[0023] In this technical solution, the bottom wall of the second container body is further provided with a second wall surface connected thereto. The second wall surface is connected to the first wall surface, and the second wall surface is inclined relative to the horizontal plane. That is, in this technical solution, the bottom wall of the second container body includes two inclined surfaces (i.e., the inclined first wall surface and the inclined second wall surface). When the height of the connection position of the two inclined surfaces is low, the connection point of the first wall surface and the second wall surface is used as the above-mentioned first position; when the height of the connection position of the two inclined surfaces is high, the connection point of the first wall surface and the second wall surface is used as the above-mentioned second position. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium is in the first position, so that the liquid vapor-liquid phase change medium is exactly in the first position.

[0024] In any of the above technical solutions, the second wall is connected to the lower end of the first wall; the first position is located at the connection between the first wall and the second wall, and the second position is located at the end of the first wall away from the second wall and / or the end of the second wall away from the first wall.

[0025] In this technical solution, the second wall is connected to the lower end of the first wall. That is, the junction between the first and second walls is located lower, and the first and second walls form a V-shaped distribution. Thus, the junction between the first and second walls serves as the first position, and the end of the first wall away from the second wall and / or the end of the second wall away from the first wall serve as the second position.

[0026] Specifically, when the container is stationary, the surface of the liquid vapor-liquid phase change medium contacts the middle of the bottom wall of the second container body and is separated from the two ends of the bottom wall of the second container body. This minimizes the contact area between the liquid vapor-liquid phase change medium and the second container body when the container is stationary. This increases the contact area between the liquid vapor-liquid phase change medium and the second container body when the container is stationary, further intensifying the intensity of the vapor-liquid phase change reaction and achieving efficient cooling of the liquid or food in the second container body.

[0027] Furthermore, when the container is stationary, only a small portion of the liquid vapor-liquid phase change medium contacts the middle or sides of the second container body, allowing for minimal heat exchange between the food or liquid in the second container body and the vapor-liquid phase change medium, ensuring uniform heat exchange. Furthermore, the user can use the temperature at the bottom of the container to determine whether to shake the container to cool the food or liquid inside. Furthermore, when shaking the container to cool the food or liquid inside, the user can control the degree of cooling by adjusting the shaking force, achieving controllable cooling.

[0028] In any of the above technical solutions, the second wall is connected to the higher end of the first wall; the second position is located at the connection between the first wall and the second wall, and the first position is located at the end of the first wall away from the second wall, and the end of the second wall away from the first wall.

[0029] In this technical solution, the second wall is connected to the higher end of the first wall. That is, the junction between the first and second walls is higher, and the first and second walls form an inverted V-shape. Thus, the junction between the first and second walls serves as the second position, while the end of the first wall facing away from the second wall and the end of the second wall facing away from the first wall serve as the first position.

[0030] That is, when the container is in a static state, the liquid surface of the liquid vapor-liquid phase change medium contacts the two ends of the bottom wall of the second container body and is separated from the middle portion of the bottom wall of the second container body, ensuring that the contact area between the liquid vapor-liquid phase change medium and the second container body is minimized when the container is in a static state. Thus, when the user shakes the container, the contact area between the liquid vapor-liquid phase change medium and the second container body increases, thereby intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body. Furthermore, when the user shakes the container, the heat of the food or liquid in the second container body is quickly transferred to the first container body. The user can quickly sense the temperature of the food or liquid in the second container body through the temperature of the first container body, making it easier to adjust the shaking force and stop shaking the container in a timely manner. In any of the above technical solutions, the bottom wall of the second container body is further provided with a first arc, which connects the first wall surface and the second wall surface and protrudes toward the bottom wall of the first container body; the first position is located on the first arc.

[0031] In this technical solution, the bottom wall of the second container body is further provided with a first arc. The second wall is connected to the lower end of the first wall, and the first arc is connected to the first wall and the second wall, and protrudes toward one side of the bottom wall of the first container body; in addition, the first position is located on the first arc. In particular, by providing the above-mentioned first arc, a smooth transition is ensured at the connection between the first wall and the second wall, and a sharp point is avoided at the connection between the first wall and the second wall, which is beneficial to improving the strength of the connection between the first wall and the second wall. In addition, the first position is located on the first arc, which can ensure that the contact area between the second container body and the liquid vapor-liquid phase change medium is appropriate, thereby ensuring that when the container is in a static state, the liquid vapor-liquid phase change medium is in small contact with the second container body.

[0032] In any of the above technical solutions, the bottom wall of the first container body is provided with a second arc, and the second arc protrudes toward the first arc.

[0033] In this technical solution, a second arc is provided on the bottom wall of the first container body, wherein the second arc is opposite to the first arc and is located directly below the first arc, and is convex toward one side of the first arc.

[0034] In any of the above technical solutions, the bottom wall of the second container body is provided with an arcuate wall surface, one of the first position and the second position is located in the middle of the arcuate wall surface, and the other of the first position and the second position is located at both ends of the arcuate wall surface.

[0035] In this technical solution, the bottom wall of the second container body is provided with a curved wall surface. That is, this technical solution optimizes the bottom wall of the second container body, and the bottom wall of the second container body includes a curved wall surface to ensure that the height of the bottom wall of the second container body is unequal, so that the lower position of the curved wall surface is directly used as the above-mentioned first position, and the higher position of the curved wall surface is used as the above-mentioned second position. This ensures that when the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium is at the first position, so that the liquid vapor-liquid phase change medium is exactly at the lower position of the curved wall surface. In addition, the curved wall surface is conducive to improving the heat transfer effect between the second container body and the vapor-liquid phase change medium, and is convenient for timely sensing the temperature of the liquid or food in the second container body.

[0036] In addition, when the curved wall surface of the bottom wall of the second container body protrudes toward the bottom wall of the first container body, and the second arc of the bottom wall of the first container body protrudes toward the bottom wall of the second container body, the distance between the curved wall surface and the second arc can be further reduced, thereby increasing the heat transfer at the curved wall surface, so that the heat is transferred from the curved wall surface to the second arc, further improving the accuracy of the user's perception of the temperature inside the container, and at the same time making it easier for the user to quickly perceive the temperature inside the container.

[0037] In any of the above technical solutions, the middle of the arcuate wall protrudes toward the top of the second container body; the second position is located in the middle of the arcuate wall, and the first position is located at both ends of the arcuate wall.

[0038] In this technical solution, the middle portion of the curved wall protrudes toward the top of the second container body. That is, the middle portion of the annular wall is positioned higher, while the ends of the curved wall are positioned lower. Thus, the second position is located in the middle of the curved wall, and the first position is located at the ends of the curved wall.

[0039] Specifically, when the container is stationary, the surface of the liquid vapor-liquid phase change medium contacts both ends of the bottom wall of the second container body and separates from the middle portion of the bottom wall of the second container body. This minimizes the contact area between the liquid vapor-liquid phase change medium and the second container body when the container is stationary. This increases the contact area between the liquid vapor-liquid phase change medium and the second container body when the container is stationary, further intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body.

[0040] In any of the above technical solutions, the middle of the arc-shaped wall protrudes toward the bottom of the second container body; the first position is located in the middle of the arc-shaped wall, and the second position is located at both ends of the arc-shaped wall.

[0041] In this technical solution, the middle portion of the curved wall protrudes toward the bottom of the second container body. That is, the ends of the annular wall are positioned higher, while the middle portion of the curved wall is positioned lower. Thus, the second position is located at the ends of the curved wall, while the first position is located in the middle portion of the curved wall.

[0042] Specifically, when the container is stationary, the surface of the liquid vapor-liquid phase change medium contacts the middle of the bottom wall of the second container body and is separated from the two ends of the bottom wall of the second container body. This minimizes the contact area between the liquid vapor-liquid phase change medium and the second container body when the container is stationary. This increases the contact area between the liquid vapor-liquid phase change medium and the second container body when the container is stationary, further intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body.

[0043] In any of the above technical solutions, the boiling point of the vapor-liquid phase change medium is greater than or equal to 40°C and less than or equal to 60°C.

[0044] In this technical solution, the boiling point of the vapor-liquid phase change medium determines the temperature of the food or liquid in the second container body after heat exchange, which indirectly determines the heat exchange effect of the food or liquid in the second container body. Under normal circumstances, warm water at 40°C to 60°C is most suitable for human drinking. Because the present invention uses a vapor-liquid 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, it effectively ensures the temperature of the hot water after heat exchange in the second container body, and ensures that the hot water after heat exchange is suitable for users to drink directly. In addition, the use of a vapor-liquid phase change medium with a boiling point of 40°C to 60°C is conducive to improving the user's suitability for drinking water, allowing users to drink warm water of a suitable temperature in a timely manner after shaking the container, and can improve the user's perception of the food or liquid in the second container body.

[0045] In any of the above technical solutions, when the container is in a static state, the ratio of the volume of the liquid vapor-liquid phase change medium to the volume of the heat exchange chamber is less than or equal to 1 / 4.

[0046] In this technical solution, the amount of vapor-liquid phase change medium directly affects the intensity of the vapor-liquid phase change, and thus the heat exchange capacity of the vapor-liquid phase change medium. When the container is stationary, the present invention ensures that the ratio of the volume of the liquid vapor-liquid phase change medium to the volume of the heat exchange chamber is less than or equal to 1 / 4. Properly designing the amount of vapor-liquid phase change medium ensures a cooling effect on the food or liquid in the second container while preventing the first container from becoming scalding due to excessive heat exchange. Setting the ratio of the volume of the liquid vapor-liquid phase change medium to the volume of the heat exchange chamber to be less than or equal to 1 / 4 can ensure that when the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium is at a first position, thereby ensuring that the liquid vapor-liquid phase change medium is in contact with the first position of the bottom wall of the second container body, and ensuring that the liquid vapor-liquid phase change medium is separated from the second position of the bottom wall of the second container body, thereby ensuring that when the container is in a static state, a part of the bottom of the second container body is in contact with the liquid vapor-liquid phase change medium for heat exchange.

[0047] Specifically, the optimal hand-warming temperature range is 40°C to 60°C. Overheating the first container body can easily burn your 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 heat exchange chamber is less than or equal to 1 / 4 effectively keeps the first container body within the 40°C to 60°C temperature range, achieving optimal heat exchange and hand-warming results.

[0048] In any of the above technical solutions, when the container is in a static state, the mass ratio of the liquid vapor-liquid phase change medium to the first container body is greater than or equal to 1:17.

[0049] In this technical solution, a greater mass of the liquid vapor-liquid phase change medium indicates that the liquid vapor-liquid phase change medium can transfer more heat during a vapor-liquid phase change, which in turn means that the liquid vapor-liquid phase change medium can absorb more heat from the food or liquid in the second container body, resulting in a higher cooling effect on the food or liquid in the second container body. Furthermore, the mass ratio of the liquid vapor-liquid phase change medium to the first container body is greater than or equal to 1:17, ensuring that the liquid level of the liquid vapor-liquid phase change medium is at a first position when the container is in a static state. This ensures that the liquid vapor-liquid phase change medium is in contact with the first position of the bottom wall of the second container body while also separating from the second position of the bottom wall of the second container body. This ensures that a portion of the bottom of the second container body is in contact with the liquid vapor-liquid phase change medium for heat exchange when the container is in a static state.

[0050] Therefore, the present invention optimizes the mass ratio of the liquid vapor-liquid phase change medium to the first container body, ensuring that the mass ratio is greater than or equal to 1:17. This ensures that sufficient vapor-liquid phase change medium continuously exchanges heat with the second container body and the first container body during the vapor-liquid phase change process, ensuring that the vapor-liquid phase change is not reduced due to condensation and aggregation, thereby ensuring the cooling efficiency of the second container body and the heating efficiency of the first container body.

[0051] In any of the above technical solutions, the wall thickness of the first container body is greater than or equal to 0.4 mm.

[0052] In this technical solution, by setting the wall thickness of the first container body to be greater than or equal to 0.4 mm, the critical load of the first container body can be increased, thereby ensuring the strength of the first container body, preventing deformation of the first container body due to structural instability, and extending the service life of the first container body and the entire container. In particular, when the user shakes the container, the liquid vapor-liquid phase change medium is converted to a gaseous vapor-liquid phase change medium, which will cause the pressure in the heat exchange chamber to increase. Setting the wall thickness of the first container body to be greater than or equal to 0.4 mm can ensure the strength of the first container body, thereby ensuring the stability of the first container body.

[0053] In any of the above technical solutions, the wall thickness of the second container body is greater than or equal to 0.5 mm.

[0054] In this technical solution, on the basis of ensuring that the bottom wall of the second container body has a first position and a second position of unequal heights, the wall thickness of the second container body is ensured to be greater than or equal to 0.5 mm. In this way, by setting the wall thickness of the second container body to be greater than or equal to 0.5 mm, the critical load of the second container body can be increased, especially the critical load of the bottom of the second container body, thereby ensuring the strength of the second container body, avoiding deformation of the second container body due to structural instability, and improving the service life of the second container body and the entire container. In particular, when the user shakes the container, the conversion of the liquid vapor-liquid phase change medium into a gaseous vapor-liquid phase change medium will cause the pressure in the heat exchange chamber to increase. Setting the wall thickness of the second container body to be greater than or equal to 0.5 mm can ensure the strength of the second container body, thereby ensuring the stability of the second container body.

[0055] In any of the above technical solutions, the bottom wall of the first container body is provided with reinforcing ribs.

[0056] In this technical solution, when a user shakes the container, the liquid vapor-liquid phase change medium transforms into a gaseous vapor-liquid phase change medium, causing the pressure within the heat exchange chamber to increase, thereby increasing the load on the first container body. Therefore, this technical solution provides reinforcing ribs on the bottom wall of the first container body to increase its strength and prevent deformation. Specifically, the bottom wall of the first container body is partially bent to form the reinforcing ribs.

[0057] Furthermore, when the middle portion of the curved wall protrudes toward the top of the second container body, the strength of the middle portion of the curved wall is relatively weak. In this case, providing the aforementioned reinforcing rib at a location on the first container body corresponding to the middle portion of the curved wall effectively improves the strength of the entire container at that location, thereby ensuring the service life of the container.

[0058] In any of the above technical solutions, a gasket is provided at the bottom of the first container body.

[0059] In this technical solution, the container further includes a gasket, which is disposed at the bottom of the first container body. The first container body can contact the placement position through the gasket, so that the gasket effectively protects the first container body and prevents the bottom of the first container body from being deformed due to collision.

[0060] In any of the above technical solutions, the gasket is a silicone gasket.

[0061] In this technical solution, the gasket is a silicone gasket. Its excellent elasticity ensures elastic contact between the first container body and the placement position, preventing rigid contact between the two. Furthermore, the silicone gasket exhibits excellent heat resistance and stability, ensuring good stability even when the user places hot liquids or food into the second container body. Furthermore, the silicone gasket is relatively inexpensive, helping to reduce the cost of the container.

[0062] In any of the above technical solutions, the thickness of the gasket is greater than or equal to 1 mm.

[0063] In this technical solution, the gasket has a thickness of greater than or equal to 1 mm. This ensures that the gasket provides support for the first container body while also providing a good isolation effect, separating the first container body from the placement location. This prevents damage to the placement location when high-temperature liquids or food are placed in the container.

[0064] In any of the above technical solutions, a sealed interlayer is formed between the first container body and the second container body, and the sealed interlayer forms a heat exchange chamber.

[0065] In this technical solution, the first and second container bodies have different sizes. After the container is assembled, the second container body is located inside the first container body, and a sealed interlayer is formed between the first and second container bodies. This invention directly uses the sealed interlayer between the first and second container bodies as a heat exchange chamber, which greatly simplifies the container structure. Furthermore, using the sealed interlayer as the heat exchange chamber ensures the heat exchange chamber's sealing properties, ensuring that the vapor-liquid phase change medium remains stably within the heat exchange chamber.

[0066] In any of the above technical solutions, the container is a water cup; the container also includes a cup cover, which is arranged on the first container body.

[0067] In this technical solution, the container is a water cup that can be used to hold hot water. The cup cools the water through a vapor-liquid phase change medium, allowing the user to drink the water at the appropriate temperature in a timely manner. Furthermore, the container includes a cup lid, which is attached to the first container body to prevent dust and other impurities from falling into the second container body and to prevent hot water from splashing out when the user shakes the cup.

[0068] In any of the above technical solutions, the vapor-liquid phase change medium includes dichloromethane.

[0069] In this technical solution, the vapor-liquid phase change medium includes dichloromethane. Dichloromethane exhibits excellent vapor-liquid phase transition properties, absorbing heat from the second container during the phase transition, thereby cooling the food and liquid within the second container. Furthermore, dichloromethane has a boiling point of approximately 39°C, ensuring that the food or liquid remains at a suitable temperature after cooling.

[0080] 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.

[0081] 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.

[0082] Refer to the following Figures 1 to 6 Containers provided according to some embodiments of the present invention are described below.

[0083] like Figure 1 、 Figure 3 and Figure 6 As shown, the first embodiment of the present invention provides a container, including: a first container body 102 , a second container body 104 , a heat exchange chamber 106 and a vapor-liquid phase change medium 108 .

[0084] Among them, Figure 1 、 Figure 3 and Figure 6 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 food or liquid. A heat exchange chamber 106 is located between the first container body 102 and the second container body 104, at least partially located at the bottom of the second container body 104. A vapor-liquid phase change medium 108 is disposed within the heat exchange chamber 106.

[0085] like Figure 1 、 Figure 3 and Figure 6As shown, the bottom wall of the second container body 104 is provided with a first position 110 and a second position 112, and the first position 110 is lower than the second position 112. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is located at the first position 110, so that the liquid vapor-liquid phase change medium 108 is just in contact with the first position 110, and the liquid vapor-liquid phase change medium 108 is separated from the second position 112.

[0086] In particular, by optimizing the bottom wall of the second container body 104, the strength and hardness of the second container body 104 can be improved, which is beneficial for extending the service life of the second container body 104. Furthermore, because the bottom wall of the second container body 104 has the first position 110 and the second position 112 of different heights, the space of the heat exchange chamber 106 is adjustable, and the filling volume of the vapor-liquid phase change medium 108 can be adjusted, providing greater flexibility.

[0087] During use of the container, the user can place high-temperature food or liquid in the second container body 104, and can change the contact area between the vapor-liquid phase change medium 108 and the second container body 104 by shaking the container, thereby adjusting the heat transfer efficiency of the vapor-liquid phase change medium 108 and achieving controllable cooling.

[0088] Specifically, after the user shakes the container, it enters the operating state, and the vapor-liquid phase change medium 108 makes large-area contact with the second container body 104. Because the second container body 104 contains high-temperature food or liquid, the temperature of the second container body 104 is relatively high, while the temperature of the first container body 102 is relatively low, generally at room temperature. Therefore, after the vapor-liquid phase change medium 108 comes into contact with the second container body 104, it absorbs heat from the second container body 104 and undergoes a vaporization reaction to become a gaseous medium. The gaseous medium then transfers heat to the first container body 102, undergoing a liquefaction reaction to become a liquid medium, thereby cooling the food or liquid in the second container body 104. Simultaneously, the heat released by the heat transfer medium to the first container body 102 raises the temperature of the first container body 102, thereby achieving the container's hand-warming function.

[0089] In particular, when the container is in a static state, a first portion 110 of the bottom wall of the second container body 104 is in contact with the liquid vapor-liquid phase change medium 108, and only the first portion 110 is in contact with the liquid vapor-liquid phase change medium 108. At this point, a small amount of heat from the second container body 104 is transferred to the liquid vapor-liquid phase change medium 108, causing the temperature of the entire bottom of the container to rise. This allows the user to sense the temperature of the food or liquid in the second container body 104 by the temperature at the bottom of the container. Furthermore, it also indicates to the user that the temperature of the food or liquid in the second container body 104 is high, prompting the user to shake the container to cool it down.

[0090] In addition, if the temperature at the bottom of the container does not rise significantly or is consistent with the room temperature, it means that the temperature of the food or liquid in the second container body 104 is appropriate. At this time, the user can determine that there is no need to shake the container to cool the food or liquid in the second container body 104.

[0091] Moreover, when the container is in a stationary state, only a small portion of the liquid vapor-liquid phase change medium 108 is in contact with the second container body 104, ensuring that the heat exchange between the vapor-liquid phase change medium 108 and the food or liquid in the second container body 104 is small, which can slow down the heat loss of the food or liquid in the second container body 104, so that the container has a certain insulation effect without the user shaking the container.

[0092] In addition, the bottom wall of the second container body 104 is designed to have different heights. When the user shakes the container, the shaking force can be adjusted to control the contact between the liquid vapor-liquid phase change medium 108 and the bottom wall of the second container body 104 at different heights, or the contact between the liquid vapor-liquid phase change medium 108 and the side wall of the second container body 104 can be controlled to adjust the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104, thereby improving the controllability of heat exchange between the vapor-liquid phase change medium 108 and the second container body 104, making it easier for users to use in daily life.

[0093] Moreover, the vapor-liquid phase change is drastic and rapid, and can absorb and release a large amount of heat instantly. The heat exchange efficiency far exceeds the heat conduction of ordinary solids or liquids, so that the vapor-liquid phase change medium 108 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 food or liquid in the second container body 104, and increases the heating rate of the first container body 102. At the same time, the vapor-liquid phase change medium 108 can be fully recycled, which is more environmentally friendly and economical.

[0094] Therefore, the container proposed in this embodiment makes full use of the vapor-liquid phase change of the vapor-liquid 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, by optimizing the shape of the bottom wall of the second container body 104, the strength and hardness of the second container body 104 are improved, so that the space of the heat exchange chamber 106 is adjustable, and the filling volume of the vapor-liquid phase change medium 108 is adjustable, which is more flexible.

[0095] The second embodiment of the present invention provides a container, which, based on the first embodiment, further comprises:

[0096] like Figure 1 and Figure 2 As shown, the bottom wall of the second container body 104 is provided with a first wall surface 114. The first wall surface 114 is inclined relative to the horizontal plane to ensure that the first bottom wall is an inclined wall surface. The first position 110 and the second position 112 are at least located at different heights of the first wall surface 114 to ensure that the first position 110 and the second position 112 are at different heights. Specifically, the first position 110 and the second position 112 can be located at opposite ends of the first wall surface 114 to ensure a sufficient height difference between the first position 110 and the second position 112.

[0097] That is, in this embodiment, the bottom wall of the second container body 104 includes an inclined surface (i.e., an inclined first wall 114), with the relatively lower end of the inclined surface serving as the first position 110, and the higher end of the inclined surface serving as the second position 112. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is positioned at the first position 110, such that the liquid vapor-liquid phase change medium 108 is located precisely at the lower end of the inclined surface. This ensures that only a small portion of the liquid vapor-liquid phase change medium 108 is in contact with the second container body 104 when the container is in a static state, allowing a small amount of heat exchange to occur between the food or liquid in the second container body 104 and the vapor-liquid phase change medium 108. This allows the user to determine whether to shake the container based on the temperature at the bottom of the container to cool the food or liquid in the second container body 104. Furthermore, when the user shakes the container to cool the food or liquid in the second container body 104 , the degree of cooling can be controlled by the shaking force, thereby achieving controllability of whether to cool the food or liquid and the degree of cooling.

[0098] In addition, the container proposed in this embodiment has all the beneficial effects of the container in Example 1. It can fully utilize the vapor-liquid phase change of the vapor-liquid phase change medium 108 to reduce the temperature of the food or liquid in the second container body 104. In addition, the entire phase change is controllable, and the filling volume of the vapor-liquid phase change medium 108 is adjustable, which is more flexible.

[0099] The third embodiment of the present invention provides a container, which, based on the first embodiment, further comprises:

[0100] like Figure 1 and Figure 2 As shown, the bottom wall of the second container body 104 is provided with a first wall surface 114 and a second wall surface 116. The first wall surface 114 is inclined relative to the horizontal plane, and the second wall surface 116 is connected to the first wall surface 114 and is inclined relative to the horizontal plane. One of the first position 110 and the second position 112 is located at the connection between the first wall surface 114 and the second wall surface 116, and the other of the first position 110 and the second position 112 is located on the first wall surface 114 and / or the second wall surface 116.

[0101] The bottom wall of the second container body 104 is further provided with a connected second wall surface 116. The second wall surface 116 is connected to the first wall surface 114 and is inclined relative to the horizontal plane. That is, in this embodiment, the bottom wall of the second container body 104 includes two inclined surfaces (i.e., the inclined first wall surface 114 and the second wall surface 116).

[0102] When the height of the connection between the two inclined surfaces is relatively low, the connection between the first wall 114 and the second wall 116 is used as the first position 110. When the height of the connection between the two inclined surfaces is relatively high, the connection between the first wall 114 and the second wall 116 is used as the second position 112. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is at the first position 110, so that the liquid vapor-liquid phase change medium 108 is exactly at the first position 110.

[0103] In this embodiment, Figure 1 and Figure 2 As shown, the second wall 116 may be connected to the lower end of the first wall 114. That is, the connection between the first wall 114 and the second wall 116 is located lower, and the first wall 114 and the second wall 116 are arranged in a V-shape. Thus, the connection between the first wall 114 and the second wall 116 serves as the first position 110, and the end of the first wall 114 away from the second wall 116 and / or the end of the second wall 116 away from the first wall 114 serves as the second position 112.

[0104] That is, when the container is in a static state, the surface of the liquid vapor-liquid phase change medium 108 contacts the middle portion of the bottom wall of the second container body 104 and is separated from the two ends of the bottom wall of the second container body 104. This ensures that when the container is in a static state, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 is minimized. Thus, when the user shakes the container, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 increases, further intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body 104.

[0105] Furthermore, when the container is stationary, only a small portion of the liquid vapor-liquid phase change medium 108 contacts the center or sides of the second container body 104. This allows for minimal heat exchange between the food or liquid in the second container body 104 and the vapor-liquid phase change medium 108, ensuring uniform heat exchange. Furthermore, the user can use the temperature at the bottom of the container to determine whether to shake the container to cool the food or liquid in the second container body 104. Furthermore, when shaking the container to cool the food or liquid in the second container body 104, the user can control the degree of cooling by adjusting the shaking force, achieving controllable cooling.

[0106] In this embodiment, the second wall 116 can be connected to the higher end of the first wall 114. That is, the connection between the first wall 114 and the second wall 116 is located higher, and the first wall 114 and the second wall 116 are arranged in an inverted V shape (this configuration is not shown in the figure). In this way, the connection between the first wall 114 and the second wall 116 is used as the second position 112, and the end of the first wall 114 away from the second wall 116 and the end of the second wall 116 away from the first wall 114 are used as the first position 110.

[0107] That is, when the container is in a static state, the liquid surface of the liquid vapor-liquid phase change medium 108 contacts both ends of the bottom wall of the second container body 104 and is separated from the middle portion of the bottom wall of the second container body 104. This ensures that when the container is in a static state, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 is minimized. Thus, when the user shakes the container, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 increases, further intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body 104. Furthermore, when the user shakes the container, the heat from the food or liquid in the second container body 104 is rapidly transferred to the first container body 102. The user can quickly sense the temperature of the food or liquid in the second container body 104 through the temperature of the first container body 102, making it easier to adjust the shaking intensity and stop shaking the container promptly.

[0108] In addition, the container proposed in this embodiment has all the beneficial effects of the container in Example 1. It can fully utilize the vapor-liquid phase change of the vapor-liquid phase change medium 108 to reduce the temperature of the food or liquid in the second container body 104. In addition, the entire phase change is controllable, and the filling volume of the vapor-liquid phase change medium 108 is adjustable, which is more flexible.

[0109] The fourth embodiment of the present invention provides a container, which, based on the third embodiment, further comprises:

[0110] like Figure 2 As shown, the bottom wall of the second container body 104 is further provided with a first arc 118. The second wall 116 is connected to the lower end of the first wall 114, and the first arc 118 is connected to the first and second walls 114, 116, and protrudes toward the bottom wall of the first container body 102. Furthermore, the first position 110 is located on the first arc 118. In particular, the provision of the first arc 118 ensures a smooth transition between the first and second walls 114, 116, avoiding a sharp point at the connection between the first and second walls 114, 116, and facilitating the strength of the connection between the first and second walls 114, 116. In addition, the first position 110 is located on the first arc 118, which can ensure that the contact area between the second container body 104 and the liquid vapor-liquid phase change medium 108 is appropriate, thereby ensuring that when the container is in a static state, the liquid vapor-liquid phase change medium 108 is in small contact with the second container body 104.

[0111] In this embodiment, further, Figure 2 As shown, a second arc 120 is provided on the bottom wall of the first container body 102. The second arc 120 is opposite to the first arc 118 and is located directly below the first arc 118. The second arc 120 is provided to bulge toward one side of the first arc 118.

[0112] In addition, the container proposed in this embodiment has all the beneficial effects of the container in Example 1. It can fully utilize the vapor-liquid phase change of the vapor-liquid phase change medium 108 to reduce the temperature of the food or liquid in the second container body 104. In addition, the entire phase change is controllable, and the filling volume of the vapor-liquid phase change medium 108 is adjustable, which is more flexible.

[0113] The fifth embodiment of the present invention provides a container, which further comprises:

[0114] like Figure 3 、 Figure 4 and Figure 6As shown, the bottom wall of the second container body 104 is provided with a curved wall surface 122. That is, this embodiment optimizes the bottom wall of the second container body 104. The curved wall surface 122 ensures that the bottom wall height of the second container body 104 is uneven, so that the lower position of the curved wall surface 122 is directly used as the first position 110, and the higher position of the curved wall surface 122 is used as the second position 112. This ensures that when the container is in a static state, the liquid level of the vapor-liquid phase change medium 108 is at the first position 110, so that the liquid vapor-liquid phase change medium 108 is exactly at the lower position of the curved wall surface 122. In addition, the curved wall surface 122 helps improve the heat transfer effect between the second container body 104 and the vapor-liquid phase change medium 108, and facilitates timely sensing of the temperature of the liquid or food in the second container body 104.

[0115] In this embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the middle portion of the curved wall 122 may be convex toward the top of the second container body 104. That is, the middle portion of the annular wall is positioned higher, while the ends of the curved wall 122 are positioned lower. Thus, the second position 112 is located in the middle portion of the curved wall 122, and the first position 110 is located at both ends of the curved wall 122.

[0116] That is, when the container is in a static state, the surface of the liquid vapor-liquid phase change medium 108 contacts both ends of the bottom wall of the second container body 104 and is separated from the middle portion of the bottom wall of the second container body 104. This ensures that when the container is in a static state, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 is minimized. Thus, when the user shakes the container, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 increases, further intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body 104.

[0117] In this embodiment, the middle portion of the curved wall 122 may be convex toward the bottom of the second container body 104. That is, the ends of the annular wall are positioned higher, while the middle portion of the curved wall 122 is positioned lower (this configuration is not shown in the figure). Thus, the second position 112 is located at the ends of the curved wall 122, and the first position 110 is located in the middle portion of the curved wall 122.

[0118] That is, when the container is in a static state, the surface of the liquid vapor-liquid phase change medium 108 contacts the middle portion of the bottom wall of the second container body 104 and is separated from the two ends of the bottom wall of the second container body 104. This ensures that when the container is in a static state, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 is minimized. Thus, when the user shakes the container, the contact area between the liquid vapor-liquid phase change medium 108 and the second container body 104 increases, further intensifying the intensity of the vapor-liquid phase change, thereby achieving efficient cooling of the liquid or food in the second container body 104.

[0119] In addition, the container proposed in this embodiment has all the beneficial effects of the container in Example 1. It can fully utilize the vapor-liquid phase change of the vapor-liquid phase change medium 108 to reduce the temperature of the food or liquid in the second container body 104. In addition, the entire phase change is controllable, and the filling volume of the vapor-liquid phase change medium 108 is adjustable, which is more flexible.

[0120] In addition, when the curved wall surface 122 of the bottom wall of the second container body 104 protrudes toward the bottom wall of the first container body 102, and the second arc 120 of the bottom wall of the first container body 102 protrudes toward the bottom wall of the second container body 104, the distance between the curved wall surface 122 and the second arc 120 can be further reduced, thereby increasing the heat transfer at the curved wall surface 122, so that heat is transferred from the curved wall surface 122 to the second arc 120, further improving the accuracy of the user's perception of the temperature inside the container, and at the same time making it easier for the user to quickly perceive the temperature inside the container.

[0121] On the basis of Examples 1 to 5, the boiling point of the vapor-liquid phase change medium 108 further determines the temperature of the food or liquid in the second container body 104 after heat exchange, which indirectly determines the heat exchange effect of the food or liquid in the second container body 104. Generally speaking, warm water between 40°C and 60°C is most suitable for human consumption. Because the present invention uses a vapor-liquid 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, it effectively ensures the temperature of the hot water in the second container body 104 after heat exchange, ensuring that the hot water after heat exchange is suitable for direct drinking by the user. In addition, the use of a vapor-liquid phase change medium 108 with a boiling point between 40°C and 60°C is conducive to improving the user's suitability for drinking water, allowing the user to promptly drink warm water at an appropriate temperature after shaking the container, and can improve the user's perception of the food or liquid in the second container body 104.

[0122] In a specific embodiment, the boiling point of the vapor-liquid phase change medium 108 may be 40° C., 45° C., 50° C., 55° C., 60° C., etc., which is not specifically limited here and can be understood by those skilled in the art.

[0123] Further, based on Examples 1 to 5, the amount of vapor-liquid phase change medium 108 directly affects the intensity of the vapor-liquid phase change, and thus the heat exchange capacity of the vapor-liquid phase change medium 108. When the container is in a static state, the present invention ensures that the ratio of the volume of the liquid vapor-liquid phase change medium 108 to the volume of the heat exchange chamber 106 is less than or equal to 1 / 4. Properly designing the amount of vapor-liquid phase change medium 108 ensures a cooling effect on the food or liquid in the second container body 104 while preventing the first container body 102 from becoming scalding due to excessive heat exchange.

[0124] Specifically, the optimal hand-warming temperature range is 40°C to 60°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 to the volume of the heat exchange chamber 106 is less than or equal to 1 / 4 effectively ensures that the first container body 102 remains within the 40°C to 60°C temperature range, achieving the optimal heat exchange and hand-warming effect.

[0125] In addition, by setting the ratio of the volume of the liquid vapor-liquid phase change medium 108 to the volume of the heat exchange chamber 106 to be less than or equal to 1 / 4, it can be ensured that when the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is at the first position 110, which ensures that the liquid vapor-liquid phase change medium 108 is in contact with the first position 110 of the bottom wall of the second container body 104, and ensures that the liquid vapor-liquid phase change medium 108 is separated from the second position 112 of the bottom wall of the second container body 104, thereby ensuring that when the container is in a static state, a part of the bottom of the second container body 104 is in contact with the liquid vapor-liquid phase change medium 108 for heat exchange.

[0126] In a specific embodiment, the ratio of the volume of the liquid phase change medium to the volume of the heat exchange chamber 106 can be 1 / 4, 1 / 5, 1 / 6, 1 / 7, etc., which is not specifically limited here and can be understood by those skilled in the art.

[0127] On the basis of the first to fifth embodiments, further, as Figure 5 As shown, a greater mass of the liquid vapor-liquid phase change medium 108 indicates that the liquid vapor-liquid phase change medium 108 can transfer more heat when a vapor-liquid phase change occurs, which also means that the liquid vapor-liquid phase change medium 108 can absorb more heat from the food or liquid in the second container body 104, and thus a higher cooling effect on the food or liquid in the second container body 104.

[0128] Therefore, the present invention optimizes the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102, ensuring that the mass ratio is greater than or equal to 1:17. This ensures that sufficient vapor-liquid phase change medium 108 continuously exchanges heat with the second container body 104 and the first container body 102 during the vapor-liquid phase change process of the vapor-liquid phase change medium 108, ensuring that the vapor-liquid phase change is not reduced due to condensation and aggregation, thereby ensuring the cooling efficiency of the second container body 104 and the heating efficiency of the first container body 102.

[0129] In addition, the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102 is greater than or equal to 1:17, which can ensure that when the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is at the first position 110, thereby ensuring that the liquid vapor-liquid phase change medium 108 is in contact with the first position 110 of the bottom wall of the second container body 104, and ensuring that the liquid vapor-liquid phase change medium 108 is separated from the second position 112 of the bottom wall of the second container body 104, thereby ensuring that when the container is in a static state, a part of the bottom of the second container body 104 is in contact with the liquid vapor-liquid phase change medium 108 for heat exchange.

[0130] In a specific embodiment, the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102 can be 1:17, 1:16, 1:15, 1:14, 1:13, 1:12, etc., which is not specifically limited here and can be understood by those skilled in the art.

[0131] In a specific embodiment, the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102 is further explained by taking the example that the complete phase change process of the liquid vapor-liquid phase change medium 108 requires the temperature of the first container body 102 to be raised from room temperature (25±5°C) to (60±5)°C.

[0132] For example, the vapor-liquid phase change medium 108 is composed of dichloromethane, and the first container body 102 is a stainless steel container. Assuming a container volume of 200 ml, the total mass of the first container body 102 is approximately 80 g. If the temperature of the first container body 102 rises by 35°C, the specific heat capacity of stainless steel (0°C to 100°C) is 0.50 J·g⁻¹K⁻¹, requiring a total of 1400 J. Dichloromethane has a boiling point of 39.8°C, a latent heat of vaporization of 330 J / g, and a specific heat capacity (liquid state from 20°C to 40°C) of 0.28 J·g⁻¹K⁻¹, requiring 4.5 g of dichloromethane to fill the container. Therefore, the mass ratio of the liquid dichloromethane to the first container body 102 is at least 1:17.

[0133] It should be noted that the above detailed explanation of the technical solution of the present invention is based solely on the example of a 200 ml container, using methylene chloride as the vapor-liquid phase change medium 108, a stainless steel container as the first container body 102, and a container volume. In actual production, the vapor-liquid phase change medium 108 is not limited to methylene chloride, and the first container body 102 is not limited to stainless steel containers. Accordingly, the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102 can be adjusted based on actual conditions.

[0134] On the basis of the first to fifth embodiments, further, as Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the wall thickness of the first container body 102 is greater than or equal to 0.4 mm. This increases the critical load of the first container body 102, thereby ensuring the strength of the first container body 102, preventing deformation of the first container body 102 due to structural instability, and extending the service life of the first container body 102 and the entire container. In particular, when the user shakes the container, the liquid vapor-liquid phase change medium 108 transforms into a gaseous vapor-liquid phase change medium 108, causing the pressure within the heat exchange chamber 106 to increase. Setting the wall thickness of the first container body 102 to greater than or equal to 0.4 mm can ensure the strength of the first container body 102, thereby ensuring its stability.

[0135] In a specific embodiment, the wall thickness of the first container body 102 can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.5 mm, 2 mm, etc., without any specific limitation herein, as long as the strength and service life of the first container body 102 are guaranteed. In a specific embodiment, the wall thickness of the first container body 102 should be less than or equal to 3 cm.

[0136] On the basis of the first to fifth embodiments, further, as Figure 1 、 Figure 3 and Figure 6As shown, while ensuring that the bottom wall of the second container body 104 has first and second locations 110 and 112 of unequal heights, the wall thickness of the second container body 104 is ensured to be greater than or equal to 0.5 mm. Thus, by setting the wall thickness of the second container body 104 to be greater than or equal to 0.5 mm, the critical load of the second container body 104, particularly the critical load at the bottom of the second container body 104, can be increased. This in turn ensures the strength of the second container body 104, prevents deformation of the second container body 104 due to structural instability, and increases the service life of the second container body 104 and the entire container. In particular, when a user shakes the container, the liquid vapor-liquid phase change medium 108 converts to a gaseous vapor-liquid phase change medium 108, causing the pressure within the heat exchange chamber 106 to increase. Setting the wall thickness of the second container body 104 to be greater than or equal to 0.5 mm ensures the strength and stability of the second container body 104.

[0137] In a specific embodiment, the wall thickness of the second container body 104 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.5 mm, 2 mm, etc., without any specific limitation herein, as long as the strength and service life of the second container body 104 are guaranteed. In a specific embodiment, the wall thickness of the second container body 104 should be less than or equal to 3 cm.

[0138] On the basis of the first to fifth embodiments, further, as Figure 6 As shown, when a user shakes the container, the liquid vapor-liquid phase change medium 108 transforms into a gaseous vapor-liquid phase change medium 108, causing the pressure within the heat exchange chamber 106 to increase, thereby increasing the load on the first container body 102. Therefore, in this embodiment, reinforcing ribs 128 are provided on the bottom wall of the first container body 102 to enhance the strength of the first container body 102 and prevent deformation of the first container body 102. Specifically, the bottom wall of the first container body 102 is partially bent to form the reinforcing ribs 128.

[0139] Furthermore, when the middle portion of the curved wall 122 protrudes toward the top of the second container body 104, the strength of the middle portion of the curved wall 122 is relatively weak. In this case, providing the aforementioned reinforcing rib 128 at a location on the first container body 102 corresponding to the middle portion of the curved wall 122 effectively improves the strength of the entire container at that location, thereby ensuring the service life of the container.

[0140] On the basis of the first to fifth embodiments, further, as Figure 1 、 Figure 2 and Figure 6As shown, the container further includes a gasket 126. The gasket 126 is disposed at the bottom of the first container body 102. The first container body 102 can contact the placement position through the gasket 126. In this way, the gasket 126 effectively protects the first container body 102 and prevents the bottom of the first container body 102 from being deformed due to collision.

[0141] Specifically, if Figure 2 and Figure 6 As shown, the gasket 126 is a silicone gasket. The silicone gasket has excellent elasticity, ensuring elastic contact between the first container body 102 and the placement position, avoiding rigid contact between the two. Furthermore, the silicone gasket has excellent heat resistance and stability, ensuring good stability when the user adds hot liquids or food to the second container body 104. Furthermore, the silicone gasket is relatively inexpensive, which helps reduce the cost of the container.

[0142] Specifically, if Figure 2 and Figure 6 As shown, the thickness of the gasket 126 is greater than or equal to 1 mm. This ensures that the gasket 126 provides support for the first container body 102 while also providing a good isolation effect, separating the first container body 102 from the storage area. This prevents the storage area from being damaged by the high temperature when high-temperature liquids or food are placed in the container.

[0143] In a specific embodiment, the thickness of the gasket 126 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc., and is not specifically limited here. As long as it can protect the container, it is feasible. In a specific embodiment, the thickness of the gasket 126 should be less than or equal to 2 cm.

[0144] On the basis of the first to fifth embodiments, further, as Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the first container body 102 and the second container body 104 have different sizes. After the container is assembled, the second container body 104 is located inside the first container body 102, and a sealed interlayer is formed between the first container body 102 and the second container body 104. The present invention directly uses the sealed interlayer between the first container body 102 and the second container body 104 as the heat exchange chamber 106, which greatly simplifies the container structure. Furthermore, using the sealed interlayer as the heat exchange chamber 106 ensures the sealing of the heat exchange chamber 106 and ensures that the vapor-liquid phase change medium 108 is stably located within the heat exchange chamber 106.

[0145] On the basis of the first to fifth embodiments, further, as Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the container is a water cup and can be used to hold hot water. The water is cooled by the vapor-liquid phase change medium 108, allowing the user to drink the water at a suitable temperature in a timely manner. In addition, the container also includes a cup cover 124. The cup cover 124 is provided on the first container body 102 to prevent external dust and other impurities from falling into the second container body 104. It also prevents the hot water in the second container body 104 from splashing when the user shakes the cup.

[0146] In addition to Examples 1 to 5, the vapor-liquid phase change medium 108 includes dichloromethane. Dichloromethane exhibits excellent vapor-liquid phase transition properties and absorbs heat from the second container body 104 during the vapor-liquid phase transition, thereby cooling the food and liquid within the second container body 104. Furthermore, the boiling point of dichloromethane is approximately 39°C, ensuring that the cooled food or liquid remains at a suitable temperature.

[0147] like Figure 1 、 Figure 3 and Figure 6 As shown, the first embodiment of the present invention provides a container comprising: a first container body 102, a second container body 104, a heat exchange chamber 106, and a vapor-liquid phase change medium 108. The second container body 104 is disposed within the first container body 102, and the interior of the second container body 104 can be used to store food or liquid. The heat exchange chamber 106 is located between the first and second container bodies 102, 104, and contains the vapor-liquid phase change medium 108. The bottom wall of the second container body 104 is defined by a first position 110 and a second position 112, with the first position 110 being lower than the second position 112. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is located at the first position 110, such that the liquid vapor-liquid phase change medium 108 is in contact with the first position 110 and separated from the second position 112.

[0148] In this embodiment, Figure 1 and Figure 2 As shown, the bottom wall of the second container body 104 may include an inclined surface (i.e., an inclined first wall 114), and the relatively lower end of the inclined surface is used as the first position 110, and the higher end of the inclined surface is used as the second position 112.

[0149] In this embodiment, Figure 1 and Figure 2As shown, the bottom wall of the second container body 104 may include two inclined surfaces (i.e., a first wall 114 and a second wall 116 arranged at an angle). When the height of the connection between the two inclined surfaces is relatively low, the connection between the first wall 114 and the second wall 116 serves as the first position 110. When the height of the connection between the two inclined surfaces is relatively high, the connection between the first wall 114 and the second wall 116 serves as the second position 112. When the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is at the first position 110, so that the liquid vapor-liquid phase change medium 108 is exactly at the first position 110. In addition, the bottom wall of the second container body 104 is further provided with a first arc 118. The second wall 116 is connected to the lower end of the first wall 114. The first arc 118 connects to the first wall 114 and the second wall 116 and protrudes toward the bottom wall of the first container body 102. The first position 110 is located on the first arc 118. In addition, a second arc 120 is provided on the bottom wall of the first container body 102 . The second arc 120 is opposite to the first arc 118 and is located directly below the first arc 118 . The second arc 120 is provided to protrude toward one side of the first arc 118 .

[0150] In this embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the bottom wall of the second container body 104 may include a curved wall surface 122 to ensure that the bottom wall height of the second container body 104 is uneven. The lower position of the curved wall surface 122 is directly designated as the first position 110, and the higher position of the curved wall surface 122 is designated as the second position 112. This ensures that when the container is in a static state, the liquid level of the liquid vapor-liquid phase change medium 108 is at the first position 110, so that the liquid vapor-liquid phase change medium 108 is located at the lower position of the curved wall surface 122. Specifically, the middle portion of the curved wall surface 122 may protrude toward the top of the second container body 104. That is, the middle portion of the annular wall surface is higher, while the ends of the curved wall surface 122 are lower. Thus, the second position 112 is located in the middle of the curved wall surface 122, and the first position 110 is located at the ends of the curved wall surface 122. Specifically, the middle portion of the curved wall 122 may be convex toward the bottom of the second container body 104. That is, the ends of the annular wall are positioned higher, while the middle portion of the curved wall 122 is positioned lower. Thus, the second position 112 is located at the ends of the curved wall 122, and the first position 110 is located at the middle portion of the curved wall 122.

[0151] In this embodiment, further, this embodiment uses a vapor-liquid 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, which effectively ensures the temperature of the hot water after heat exchange in the second container body 104, and ensures that the hot water after heat exchange is suitable for users to drink directly.

[0152] In this embodiment, further, this embodiment ensures that the ratio of the volume of the vapor-liquid phase change medium 108 in the liquid state to the volume of the heat exchange chamber 106 is less than or equal to 1 / 4. The reasonable design of the amount of the vapor-liquid phase change medium 108 ensures the cooling effect on the food or liquid in the second container body 104 on the one hand, and at the same time avoids the situation where the first container body 102 is scalded due to excessive heat exchange.

[0153] In this embodiment, the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102 is further optimized to ensure that the mass ratio of the liquid vapor-liquid phase change medium 108 to the first container body 102 is greater than or equal to 1:17. This ensures that the vapor-liquid phase change is not reduced due to condensation and aggregation, thereby ensuring the cooling efficiency of the second container body 104 and the heating efficiency of the first container body 102.

[0154] In this embodiment, further, Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the wall thickness of the first container body 102 is greater than or equal to 0.4 mm, and the wall thickness of the second container body 104 is greater than or equal to 0.5 mm. In addition, the bottom wall of the first container body 102 is provided with reinforcing ribs 128 to enhance the strength of the first container body 102 and prevent deformation of the first container body 102.

[0155] In this embodiment, further, Figure 2 and Figure 6 As shown, a gasket 126 is provided at the bottom of the first container body 102. The gasket 126 effectively protects the first container body 102 and prevents the bottom of the first container body 102 from deformation due to collisions. Specifically, the gasket 126 is a silicone gasket. In addition, the thickness of the gasket 126 is greater than or equal to 1 mm.

[0156] In this embodiment, further, Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, the first container body 102 and the second container body 104 have different sizes. After the container is assembled, the second container body 104 is located inside the first container body 102, and a sealed interlayer is formed between the first container body 102 and the second container body 104. The first container body 102 and the second container body 104 have different sizes. After the container is assembled, the second container body 104 is located inside the first container body 102, and a sealed interlayer is formed between the first container body 102 and the second container body 104.

[0157] In this embodiment, further, Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the container is a water cup and can be used to hold hot water. The water is cooled by the vapor-liquid phase change medium 108, allowing the user to drink the water at a suitable temperature in a timely manner. In addition, the container also includes a cup cover 124. The cup cover 124 is provided on the first container body 102 to prevent external dust and other impurities from falling into the second container body 104. It also prevents the hot water in the second container body 104 from splashing when the user shakes the cup.

[0158] In this embodiment, further, the vapor-liquid phase change medium 108 includes dichloromethane.

[0159] like Figure 1 、 Figure 3 and Figure 6 As shown, the container proposed in this embodiment improves the strength and hardness of the second container body 104 by optimizing the bottom wall of the second container body 104, thereby increasing the service life of the second container body 104. Furthermore, because the bottom wall of the second container body 104 has first and second positions 110 and 112 of varying heights, the space of the heat exchange chamber 106 is adjustable, enabling adjustable filling volume of the vapor-liquid phase change medium 108 and providing greater flexibility. Furthermore, during use, the user can place high-temperature food or liquids in the second container body 104 and shake the container to change the contact area between the vapor-liquid phase change medium 108 and the second container body 104, thereby adjusting the heat transfer efficiency of the vapor-liquid phase change medium 108 and achieving controllable cooling.

[0160] Specifically, after the user shakes the container, it enters the operating state, and the vapor-liquid phase change medium 108 makes large-area contact with the second container body 104. Because the second container body 104 contains high-temperature food or liquid, the temperature of the second container body 104 is relatively high, while the temperature of the first container body 102 is relatively low, generally at room temperature. Therefore, after the vapor-liquid phase change medium 108 comes into contact with the second container body 104, it absorbs heat from the second container body 104 and undergoes a vaporization reaction to become a gaseous medium. The gaseous medium then transfers heat to the first container body 102, undergoing a liquefaction reaction to become a liquid medium, thereby cooling the food or liquid in the second container body 104. Simultaneously, the heat released by the heat transfer medium to the first container body 102 raises the temperature of the first container body 102, thereby achieving the container's hand-warming function.

[0161] Moreover, the vapor-liquid phase change is drastic and rapid, and can absorb and release a large amount of heat instantly. The heat exchange efficiency far exceeds the heat conduction of ordinary solids or liquids, so that the vapor-liquid phase change medium 108 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 food or liquid in the second container body 104, and increases the heating rate of the first container body 102. At the same time, the vapor-liquid phase change medium 108 can be fully recycled, which is more environmentally friendly and economical.

[0162] Therefore, the container proposed in this specific embodiment fully utilizes the vapor-liquid phase change of the vapor-liquid phase change medium 108, can instantly absorb and release a large amount of heat, accelerates the rate of the entire heat conduction, and greatly improves the heat exchange efficiency of the container; and, by optimizing the shape of the bottom wall of the second container body 104, the strength and hardness of the second container body 104 are improved, so that the space of the heat exchange chamber 106 is adjustable, and the filling volume of the vapor-liquid phase change medium 108 is adjustable, which is more flexible.

[0163] In a specific embodiment, a container such as a water cup is an essential item for holding drinking liquids. When hot water is poured into a water cup, it often takes a long time to cool to the appropriate drinking temperature. This often results in people being unable to drink water because the water in the cup is too hot when they are in a hurry, causing significant inconvenience. To quickly cool the liquid in the cup, a related technique employs a stirring rod and a micromotor within the cavity. The micromotor drives the stirring rod to stir the liquid within the cavity, thereby rapidly dissipating the heat from the liquid. However, this cooling method results in a complex structure for the water cup and high production costs.

[0164] The second specific embodiment of the present invention provides a container with a simple structure, convenient cooling and low cost, which can effectively solve the above technical problems.

[0165] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the container proposed in this embodiment can achieve rapid heat exchange through vapor-liquid phase change. The container includes a cup lid 124, a first container body 102, and a second container body 104. A sealed interlayer is provided between the first container body 102 and the second container body 104, forming a heat exchange chamber 106. A liquid vapor-liquid phase change medium 108 is disposed within the heat exchange chamber 106, which is used to transfer heat from the second container body 104 to the first container body 102. In this way, by setting the container as a first container body 102 and a second container body 104, a vapor-liquid phase change medium 108 is set in the heat exchange chamber 106 between the first container body 102 and the second container body 104; when hot water is poured into the second container body 104, the liquid vapor-liquid phase change medium 108 will quickly transfer the heat in the second container body 104 to the first container body 102, so that the hot water in the second container body 104 is cooled, and the outside of the first container body 102 has functions such as heating and warming hands. The structure is very simple, the heat exchange speed is fast and the cost is low.

[0166] The container proposed in this specific embodiment has at least the following typical advantages: first, the heat exchange chamber 106 is provided with a vapor-liquid phase change medium 108, and heat exchange is performed by utilizing vapor-liquid phase changes, and the heat exchange process is uniform and efficient; second, the vapor-liquid phase change medium 108 is safe, pollution-free, and reusable; third, the vapor-liquid phase change medium 108 is widely available and relatively low in price.

[0167] In a specific embodiment, Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, the container includes a cup cover 124, a first container body 102 and a second container body 104, the second container body 104 is arranged in the second container body 104, a heat exchange chamber 106 is formed between the first container body 102 and the second container body 104, and a vapor-liquid phase change medium 108 is arranged in the heat exchange chamber 106.

[0168] In a specific embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, the bottom wall of the second container body 104 is provided with a first position 110 and a second position 112, with the first position 110 being lower than the second position 112. By shaking the container, the user can adjust the interface area between the vapor-liquid phase change medium 108 and the second container body 104, thereby adjusting the heat transfer rate. When the container is stationary, the vapor-liquid phase change medium 108 is a low-boiling-point liquid, such as dichloromethane. The vapor-liquid phase change medium 108 achieves heat transfer through vapor-liquid phase changes.

[0169] In a specific embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the bottom wall of the second container body 104 is provided with a first position 110 and a second position 112, and the first position 110 is lower than the second position 112. When the container is in a static state, the liquid vapor-liquid phase change medium 108 is at the bottom of the second container body 104 and contacts the first position 110 of the bottom wall of the second container body 104. At this time, the vapor-liquid phase change medium 108 has a small amount of contact with the second container body 104, and the vapor-liquid phase change occurs slowly; after the user shakes the container, the vapor-liquid phase change medium 108 fully contacts the side walls and side walls of the second container body 104, thereby accelerating the operation of the vapor-liquid phase change medium 108 and ensuring the heat transfer efficiency of the vapor-liquid phase change.

[0170] In a specific embodiment, the boiling point of the vapor-liquid phase change medium 108 is generally 40° C. to 60° C.; when the container is in a static state, the ratio of the volume of the liquid vapor-liquid phase change medium 108 to the volume of the heat exchange chamber 106 is less than or equal to 1 / 4.

[0171] In a specific embodiment, when the container is in operation, hot water is poured into the second container body 104 (hot water is used here as an example to further explain the container proposed by the present invention, and does not mean that the container proposed by the present invention can only hold hot water), and then the container is shaken to ensure that the vapor-liquid phase change medium 108 in the heat exchange chamber 106 is in full contact with the second container body 104. Because the boiling point of the vapor-liquid phase change medium 108 is lower than the temperature of the second container body 104, the second container body 104 will undergo a vaporization reaction and absorb heat from the second container body 104; the gaseous vapor-liquid phase change medium 108 will release heat and condense into a liquid medium when it encounters the first container body 102 with a lower temperature. The heat of the second container body 104 is then transferred to the first container body 102, thereby cooling the second container body 104 and the hot water, and simultaneously realizing the hand-warming function of the container.

[0172] In addition, a small amount of the liquid medium produced by condensation adheres to the side wall of the first container body 102, while most of it slides down the side wall of the first container body 102 and settles on the side wall of the second container body 104. The bottom wall of the second container body 104 is provided with a first position 110 and a second position 112 of different heights. When the container is in a static state, the liquid vapor-liquid phase change medium 108 contacts the first position 110. At this time, the contact area between the vapor-liquid phase change medium 108 and the second container body 104 is small, and the heat transfer reaction occurs relatively slowly. By shaking the container, the heat transfer efficiency can be accelerated. In this way, the controllability of the vapor-liquid phase change is achieved. In addition, the entire heat transfer process fully utilizes the characteristic that the vapor-liquid phase change can instantly absorb and release a large amount of heat energy, accelerating the rate of heat conduction and greatly improving the heat exchange efficiency.

[0173] In addition, the vapor-liquid phase change medium 108 can be an organic low-boiling point substance with a boiling point generally between 40°C and 60°C, such as dichloromethane; after the liquid vapor-liquid phase change medium 108 is completely reacted, the temperature of the first container body 102 can be raised from room temperature (25±5°C) to (60±5)°C.

[0174] In a specific embodiment, the thickness of the first container body 102 is 0.4 mm, and the phase change medium is methylene chloride. Assuming a container volume of 200 ml, the total mass of the first container body 102 is approximately 80 g. If the temperature of the first container body 102 rises by 35°C, the specific heat capacity of stainless steel (0-100°C) is 0.50 J·g⁻¹K⁻¹, requiring a total of 1400 J. Methylene chloride has a boiling point of 39.8°C, a latent heat of vaporization of 330 J / g, and a specific heat capacity (liquid state, 20-40°C) of 0.28 J·g⁻¹K⁻¹, requiring 4.5 g of methylene chloride to fill the container. In other words, when the container is stationary, the mass of the liquid vapor-liquid phase change medium 108 should be at least 1:17 relative to the mass of the first container body 102.

[0175] In addition, the wall thickness of the first container body 102 is greater than or equal to 0.4 mm, which increases the critical load of the first container body 102 and thus ensures the strength of the first container body 102. The wall thickness of the second container body 104 is greater than or equal to 0.5 mm, which increases the critical load of the second container body 104 and thus ensures the strength of the second container body 104. Reinforcing ribs 128 are provided on the bottom wall of the first container body 102 to increase the strength of the first container body 102 and prevent deformation of the first container body 102. A gasket 126 is provided at the bottom of the first container body 102 to prevent deformation of the bottom of the first container body 102 due to collision. The gasket 126 is a silicone gasket, and the thickness of the gasket 126 is greater than or equal to 1 mm.
