Description

Technical Field

[0001] This application relates to the field of heat storage technology, and in particular to a heat storage device and a refrigerated cup. Background Technology

[0002] Refrigerated containers can be used to store substances that need to be preserved at specific temperatures. For example, they can be used to store substances requiring low-temperature storage, such as breast milk and medicine. The contents of a refrigerated container are preserved at low temperatures by releasing cold air through a heat-storing material. In traditional refrigerated containers, the heat-storing material is stored in a single, integrated cavity. During freezing, this material tends to accumulate in large quantities at the bottom of the cavity, potentially causing the outer shell to burst due to excessive pressure, thus reducing the reliability of the heat-storing container. Utility Model Content

[0003] This application provides a heat storage device and a refrigerated cup, which aims to improve the problem of excessive local pressure in the heat storage shell.

[0004] To achieve the above-mentioned technical effects, one technical solution adopted in this application is: to provide a heat storage device for a refrigerated cup. The heat storage device includes a plurality of accommodating members arranged along a first direction. Each accommodating member includes a first wall and a second wall arranged opposite to each other. The first wall and the second wall are connected, and the first wall and the second wall enclose a cavity for accommodating heat storage material. The first direction extends along the depth direction of the refrigerated cup.

[0005] The heat storage device in this application example can be used as a cold source for a refrigerator cup to keep the contents of the refrigerator cup warm. This application uses a first wall and a second wall arranged opposite to each other to form a cavity for accommodating heat storage material, which can conveniently store the heat storage material in the cavity so that the refrigerator cup can be used to store a cold source. By using multiple accommodating members arranged along the first direction, the heat storage device can be divided into multiple heat storage units along the first direction to reduce the volume of a single heat storage unit and the amount of heat storage material in a single heat storage unit. This reduces the pressure on the bottom of the accommodating member when the heat storage material accumulates at the bottom of the accommodating member, thus reducing the problem that the bottom of the accommodating member is prone to bursting.

[0006] This application also proposes a refrigerator cup, comprising:

[0007] The cup body has a heat storage chamber inside; and

[0008] As described above, the heat storage device is located inside the heat storage chamber. Attached Figure Description

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0030] Refrigerated containers can store a certain amount of heat-storing material. When substances requiring low-temperature preservation, such as insulin and breast milk, are placed in the container, the heat-storing material can keep the contents warm, reducing the possibility of spoilage. In existing technologies, to facilitate the injection of the heat-storing material, a cavity is typically provided within the refrigerator container to hold it. However, because the heat-storing material tends to deposit at the bottom of the cavity after heat exchange, excessive pressure at the bottom of the refrigerator container can easily cause it to burst.

[0031] To address the aforementioned problems, this application proposes a heat storage device that can reduce the pressure at the bottom of a refrigerator cup. In this heat storage device, multiple accommodating components are formed by dividing the heat storage device into multiple accommodating components arranged along a first direction. Each accommodating component contains an independent heat storage unit. By reducing the amount of heat storage material stored in a single heat storage unit, the weight of the heat storage material in a single accommodating component is reduced while the surface area of ​​the lower surface of the accommodating component remains unchanged. This reduces the pressure of the heat storage material in a single accommodating component on the bottom of the accommodating component, thereby reducing the possibility of the refrigerator cup bursting.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The heat storage device 10 in this application example can be used in the refrigerator cup 100. The heat storage device 10 can be installed at a preset position inside the refrigerator cup 100 to release cold energy at the preset position inside the refrigerator cup 100 so that the contents of the refrigerator cup 100 maintain a preset temperature. In some examples, the refrigerator cup 100 has a depth direction, and the heat storage device 10 can be placed inside the refrigerator cup 100 along the depth direction of the refrigerator cup 100.

[0033] Please refer to the following: Figure 4 and Figure 5This application provides an example of a heat storage device 10 for a refrigerator cup 100. The refrigerator cup 100 has a depth direction. The heat storage device 10 includes a plurality of accommodating members 11 arranged along a first direction a. Each accommodating member 11 includes a first wall 111 and a second wall 112 disposed opposite to each other. The first wall 111 is connected to the second wall 112, and the first wall 111 and the second wall 112 enclose a cavity 113 for accommodating a heat storage material 30. The first direction a extends along the depth direction of the refrigerator cup 100.

[0034] The cavities 113 of the multiple accommodating members 11 can be used to accommodate the heat storage material 30. In this example, the materials of the multiple accommodating members 11 can be the same or different. Each accommodating member 11 includes a first wall 111 and a second wall 112 disposed opposite to each other, wherein a gap exists between the first wall 111 and the second wall 112 to form a cavity 113 for accommodating the heat storage material 30. The cavity 113 can be a cavity that is completely closed after the heat storage material 30 is injected. In this example, the first wall 111 and the second wall 112 can be enclosed to form a cuboid, a hollow cylinder, or other shapes. In some examples, the first wall 111 is fitted around the outer periphery of the second wall 112, so that the first wall 111 and the second wall 112 enclose a hollow cylindrical structure, forming an annular cavity 113 between the first wall 111 and the second wall 112.

[0035] Multiple accommodating elements 11 are arranged along the first direction a to achieve a regular distribution. In this example, the surfaces of the multiple accommodating elements 11 along the first direction a can be attached to or connected to each other, or the multiple accommodating elements 11 can be spaced apart along the first direction a. In this application example, the heat storage device 10 can be divided into multiple accommodating elements 11 of equal height along the first direction a, and the volume of the cavity 113 of each accommodating element 11 can be the same; in some examples, the heights of the multiple accommodating elements 11 along the first direction a can be unequal. In some examples, the bottom areas of the bottom surfaces of the multiple accommodating elements 11 along the first direction a can be equal. In some examples, the amount of heat storage material 30 injected into different accommodating elements 11 can be equal or unequal.

[0036] In this example, multiple accommodating members 11 are arranged along the first direction a to form a heat storage device 10, thus dividing the entire heat storage device 10 into multiple heat storage units. Under the premise that the total height of the refrigerator cup 100 remains unchanged, the amount of heat storage material 30 stored in a single heat storage unit will be less than the amount of heat storage material 30 in an existing integrated refrigerator cup 100. Users can arrange the heat storage device 10 in such a way as... Figure 3 and Figure 4When the container 11 is placed in the first direction 'a', and assuming the material of the container 11 remains unchanged, if the surface area of ​​the bottom of the container 11 remains unchanged, but the amount of heat storage material 30 in a single heat storage unit decreases, the pressure of the heat storage material 30 in a single heat storage unit on the bottom of the container 11 will decrease, thereby reducing the possibility of the bottom of the container 11 bursting. In some examples, arrows or other markings can be provided on the outer surface of the heat storage device 10 to inform the user of the optimal placement direction when freezing the heat storage device 10.

[0037] In this example, the cavity 113 of the accommodating component 11 is used to accommodate the heat storage material 30. In this example, the heat storage material 30 can be injected during the process of sealing the accommodating component 11, so that the filling of the heat storage material 30 can be completed simultaneously while sealing the accommodating component 11. In some examples, when forming the accommodating component 11, an injection port 114 for filling the heat storage material 30 can be reserved on the accommodating component 11, so that the injection operation can be carried out separately through other equipment and processes after the preparation of the accommodating component 11 is completed.

[0038] In some examples, at least one receiving element 11 is provided with an injection port 114, which connects to the cavity 113 of the corresponding receiving element 11. The injection port 114, connecting to the cavity 113, is used to connect an injection device for injecting the heat storage material 30 into the cavity 113. In this example, the injection port 114 can be a through hole formed in the receiving element 11. In some examples, after the operation of injecting the heat storage material 30 into the cavity 113 is completed, the injection port 114 can be sealed by a heat fusion process; in some examples, the injection port 114 can also be sealed by a sealing structure independent of the receiving element 11.

[0039] In some examples, at least one injection port 114 can be provided on each accommodating element 11, and heat storage material 30 can be injected into the corresponding accommodating element 11 through each injection port 114, so as to determine the injection amount of heat storage material 30 in a single accommodating element 11 according to the specific situation.

[0040] Please see Figure 5 and Figure 6In some examples, at least two adjacent accommodating elements 11 are interconnected by connecting segments 12. In this example, connecting two adjacent accommodating elements 11 by connecting segments 12 facilitates the simultaneous placement and removal of at least two accommodating elements 11. In this example, the connecting segment 12 may be made of the same material as the first wall 111 or the second wall 112, and at least one of the first wall 111 and the second wall 112 may be extended outward to form the connecting segment 12. In some examples, an intermediate connecting element may be additionally provided on two adjacent accommodating elements 11 as the connecting segment 12. In some examples, multiple accommodating elements 11 of the heat storage device 10 may be sequentially interconnected by connecting segments 12, so that the multiple accommodating elements 11 of the heat storage device 10 can form a single unit. In the examples of this application, when multiple independent connecting segments 12 are used to connect two adjacent accommodating elements 11, the volume and number of connecting segments 12 can be determined based on at least one of the following factors: the volume of the accommodating element 11, its installation position in the refrigerated cup, and the amount of heat storage material contained therein.

[0041] Please see Figure 6 In some examples, at least one connecting segment 12 has a through hole 121, which connects the cavities 113 of the two adjacent receiving members 11. The through hole 121 extends through the connecting segment 12, connecting the cavities 113 of the two adjacent receiving members 11, allowing the heat storage material 30 to enter the cavity 113 of the other receiving member 11 through the hole 121. In this example, by using the through hole 121 to connect the two adjacent receiving members 11, when injecting the heat storage material 30 through the injection port 114, the heat storage material 30 can be injected into at least two receiving members 11 through one injection port 114. The number of through holes 121 in this example can be one or more, and the number and diameter of the through holes 121 can be determined according to the type of heat storage material 30 and parameters such as the material and volume of the receiving members 11. In some examples, multiple accommodating elements 11 are connected to each other in sequence via connecting sections 12. The heat storage device 10 may be provided with only one injection port 114, through which heat storage material 30 is injected into multiple accommodating elements 11, thereby reducing the number of injection ports 114 opened on the heat storage device 10 and reducing the processing difficulty of the accommodating elements 11.

[0042] In some examples, the injection port 114 is located at one end of the heat storage device 10 along the first direction a, and multiple accommodating elements 11 are connected sequentially along the first direction a. In this example, since multiple accommodating elements 11 are connected sequentially along the first direction a, the heat storage material 30 can be injected into multiple accommodating elements 11 through only one injection port 114 located at one end of the heat storage device 10 along the first direction a. Therefore, it is necessary to open the injection port 114 at one end of the heat storage device 10 located in the first direction a. On the one hand, this helps to simplify the structure of the heat storage device 10. On the other hand, it can reduce the problem of affecting the structural strength of the corresponding accommodating elements 11 due to setting injection ports 114 on multiple accommodating elements 11. Furthermore, the heat storage material 30 in multiple cavities 113 can flow through the through hole 121, thereby reducing the problem of excessive amount of heat storage material 30 contained in a single cavity 113. In some examples, the axes of the connecting sections 12 between multiple accommodating elements 11 can be on the same straight line to facilitate opening multiple connecting sections 12 at the same position.

[0043] In some examples, the minimum inner diameter of the through-hole 121 furthest from the injection port 114 is smaller than that of the through-hole 121 closest to the injection port 114. In this example, the minimum inner diameter of the through-hole 121 closest to the injection port 114 is relatively larger than that furthest from the injection port 114. With the injection port 114 facing upwards, when the heat storage material 30 is injected, the heat storage material 30 flows sequentially along multiple through-holes 121 toward the end furthest from the injection port 114. Because the minimum inner diameter of the through-hole 121 in the connecting section 12 furthest from the injection port 114 is smaller than that in the end closest to the injection port 114, the flow rate of the heat storage material 30 toward the cavity 113 furthest from the injection port 114 is relatively slow. In this example, the end with the liquid injection port 114 can be used as the upper end of the heat storage device 10. When injecting liquid, the speed at which the heat storage material 30 enters the lowermost cavity 113 of the heat storage device 10 can be slowed down, thereby reducing the problem of excessive amount of heat storage material 30 contained in the lowermost cavity 113.

[0044] In some examples, at least a portion of the first wall 111 is made of a malleable material. In this example, a malleable material refers to a material that can undergo tensile deformation within a certain range under external force, and can return to its original shape when the external force disappears. Taking silicone as an example, when the first wall 111 is subjected to pressure from the heat storage material 30, the silicone portion of the first wall 111 can deform within a certain range to adaptively adjust according to the amount of heat storage material 30. Therefore, by using a first wall 111 with a malleable material in this example, the first wall 111 can have a certain range of deformation properties, thereby reducing the possibility of the first wall 111 cracking under pressure. In this example, the first wall 111 can be made entirely of a malleable material or partially of a malleable material.

[0045] In some examples, the difference from the previous example is that at least a portion of the second wall 112 is made of a malleable material. The technical effect of at least a portion of the second wall 112 being made of a malleable material in this example is the same as in the previous example, and will not be repeated here.

[0046] In some examples, both the first wall 111 and the second wall 112 comprise a malleable material. Optionally, the first wall 111 and the second wall 112 can be an integral structure made of malleable material. In this example, the first wall 111 and the second wall 112 can be enclosed to form a hollow structure that can deform under pressure. Taking silicone as an example, the first wall 111 and the second wall 112 can be enclosed to form a silicone capsule structure. When the heat storage material 30 gathers in a specific direction, the shape of the accommodating member 11 can be adaptively adjusted by the malleable properties of silicone to reduce the problem of bursting caused by excessive local stress on the rigid material of the accommodating member 11.

[0047] Please see Figure 7 In some examples, the heat storage device 10 also includes a housing 13, which includes a third wall 131 and a fourth wall 132 disposed opposite to each other. The third wall 131 and the fourth wall 132 are connected and enclose to form an inner cavity 133, and at least part of the receiving member 11 is disposed in the inner cavity 133.

[0048] The outer casing 13 is used to enclose at least one receiving element 11 to protect it. The outer casing 13 includes a third wall 131 and a fourth wall 132 disposed opposite to each other, connected to each other, with a gap between them to form an inner cavity 133. This inner cavity 133 can accommodate at least one receiving element 11. In this example, the volume of the inner cavity 133 can be adapted to the volume of the heat storage device 10. In some examples, multiple receiving elements 11 are disposed within the inner cavity 133, which can seal the outer casing 13 to form a closed structure. In some examples, the outer casing 13 can be made of a rigid material, such as stainless steel, which allows for shaping of the heat storage device 10 and forms a second sealing layer, thereby reducing the possibility of leakage of the heat storage material 30.

[0049] In some examples, the heat storage device 10 also includes a protective sleeve 14, which is fitted over the exterior of the housing 13. The protective sleeve 14 serves to insulate the exterior of the housing 13, reducing the risk of user injury due to excessively high or low surface temperatures of the housing 13. In some examples, at least a portion of the protective sleeve 14 is made of silicone, which improves its insulation performance and allows it to adhere more easily to the outer surface of the housing 13, reducing the likelihood of the protective sleeve 14 falling off.

[0050] Please see Figure 8 In some examples, at least one receiving member 11 is divided into multiple sub-receiving members 115 arranged along a second direction b, which is at an angle to the first direction a. In this example, the second direction b being at an angle to the first direction a means that the second direction b is not parallel to the first direction a. In this example, by dividing at least one receiving member 11 into multiple sub-receiving members 115 arranged along the second direction b, the possibility of the receiving member 11 bursting due to compression of the heat storage material 30 within a single heat storage unit can be reduced by further reducing the amount of heat storage material 30 contained within the unit.

[0051] In some examples, the first wall 111 and the second wall 112 are inner and outer sleeves, and at least part of the cavity 113 is arranged in a ring shape. In this example, the first wall 111 can be sleeved on the outer periphery of the second wall 112 so that the heat storage device 10 forms a hollow ring structure. When the heat storage device 10 is placed in the refrigerator cup 100, a ring-shaped heat storage area can be formed in the refrigerator cup 100. The contents such as baby bottles and insulin can be placed in the ring-shaped heat storage area to improve the temperature uniformity of the contents.

[0052] Please refer to the following: Figures 9 to 12In some examples, at least one of the first wall 111 and the second wall 112 has an injection port 114; a fastener 15 for sealing the injection port 114 is provided on the injection port 114. In this example, the injection port 114 may be provided on only one of the first wall 111 and the second wall 112, or the injection port 114 may be provided on both the first wall 111 and the second wall 112. The fastener 15 is provided on the injection port 114 to seal the injection port 114, so that the cavity 113 is in a closed state. In this example, the position of the injection port 114 may be determined according to the installation method and shape of the heat storage device 10. The fastener 15 may be fixed to the injection port 114 of the receiving member 11 by at least one of threaded connection, snap-fit ​​or pin connection.

[0053] Please see Figure 11 In some examples, an elastic seal 16 is provided between the fastener 15 and the injection port 114. The elastic seal 16 is used to seal the gap between the fastener 15 and the injection port 114. The elastic seal 16 can be a sealing gasket or other sealing material that can elastically deform under external force. The elastic seal 16 is disposed within the gap between the fastener 15 and the injection port 114 to seal the gap. In some examples, the fastener 15 can be connected to the injection port 114 by a threaded connection. When the fastener 15 is threaded onto the receiving member 11, the elastic seal 16 can be pressed between the fastener 15 and at least one inner wall surface of the injection port 114. In this example, by using a combination of the fastener 15 and the elastic seal 16, the problem of easy seal detachment caused by the existing use of elastic silicone as a seal to seal the injection port 114 can be avoided, which helps to improve the reliability of the seal of the injection port 114.

[0054] In some examples, the first wall 111 is fitted around the periphery of the second wall 112, and the injection port 114 is at least partially a through hole 121 formed on the first wall 111. In this example, the first wall 111 can be fitted around the periphery of the second wall 112 to form a hollow annular structure of the heat storage device 10. When the heat storage device 10 is placed inside the refrigerator cup 100, an annular heat storage area can be formed inside the refrigerator cup 100. The contents of the baby bottle, insulin, etc., can be placed in the annular heat storage area to improve the temperature uniformity of the contents. In this example, the injection port 114 is located on the first wall 111, which allows the heat storage material 30 to be injected into the cavity 113 from the outside of the heat storage device 10, thereby improving the convenience of injecting the heat storage material 30. In some examples, the distance between the injection port 114 and the two ends of the receiving member 11 along the first direction a is greater than zero, that is, the injection port 114 is not opened at the end of the receiving member 11 along the first direction a. After sealing the injection port 114, the influence of the fastener 15 on the adjacent receiving member 11 can be reduced, thereby facilitating the stacking and installation of adjacent receiving members 11.

[0055] In some examples, the heat storage device 10 also includes a protective sleeve 14, which is fitted around the periphery of the first wall 111. The protective sleeve 14 serves to insulate the exterior of the housing 11, reducing the risk of user injury due to excessively high or low surface temperatures of the housing 11. In some examples, the protective sleeve 14 is at least partially made of silicone, which improves its insulation effect and makes it easier for the protective sleeve 14 to adhere to the outer wall surface of the housing 11, reducing the possibility of the protective sleeve 14 falling off.

[0056] In some examples, the protective sleeve 14 covers at least the outer surface of the fastener 15 so that the protective sleeve 14 can be used to limit the fastener 15, which can further improve the reliability of the fastener 15 and reduce the impact of the exposed fastener 15 on the appearance of the heat storage device 10.

[0057] In some examples, the first wall 111 is fitted around the second wall 112, and the first wall 111 has an injection port 114. At least the first wall 111 is made of a rigid material. In this example, the first wall 111 is made of a rigid material, which improves the structural stability of the receiving member 11 and facilitates the opening of the injection port 114 on the first wall 111. It also makes it easier for the fastener 15 to engage with the first wall 111, reducing the possibility of the fastener 15 detaching from the injection port 114. In some examples, the second wall 112 can also be made of a rigid material to further enhance the structural strength of the receiving member 11. In some examples, both the first wall 111 and the second wall 112 can be made of stainless steel.

[0058] Please see Figure 12In some examples, multiple accommodating components 11 are arranged independently of each other, and the multiple accommodating components 11 are stacked along the first direction a. In this example, the multiple accommodating components 11 are arranged separately, and the number of accommodating components 11 to be installed can be determined according to the volume of the refrigeration cup 100, so that the heat storage device 10 can be easily assembled according to the actual situation.

[0059] Please see Figure 1 , Figure 2 and Figure 3 Based on the above-mentioned heat storage device 10, this application also proposes an example of a refrigerator cup 100, which includes a cup body 20 and a heat storage device 10 as in any of the above examples. A heat storage chamber 23 is provided inside the cup body 20, and the heat storage device 10 is disposed inside the heat storage chamber 23.

[0060] In this example, the shape and volume of the cup body 20 can be determined according to actual needs. The cup body 20 is at least partially hollow to form a heat storage cavity 23 for placing the heat storage device 10. After the heat storage device 10 is placed in the heat storage cavity 23, the heat storage device 10 can release heat or cold in the heat storage cavity 23 to keep the contents of the heat storage cavity 23 at a preset temperature.

[0061] In some examples, the cup body 20 includes a fifth wall 21 and a sixth wall 22 sleeved around the fifth wall 21, with a heat storage cavity 23 formed inside the fifth wall 21; there is a gap between the fifth wall 21 and the sixth wall 22. In this example, the gap between the fifth wall 21 and the sixth wall 22, and the inner and outer sleeves of the fifth wall 21 and the sixth wall 22, can form a double-layer wall structure for the cup body 20, thereby improving the heat preservation performance of the cup body 20.

[0062] In some examples, the cup body 20 is closed at one end along the first direction a, and the other end has an opening 24 for the heat storage device 10 to be inserted into the heat storage chamber 23. The refrigerator cup 100 also includes a lid 25, which is used to close the opening 24. The opening 24 can be used to place the heat storage device 10 and the contents that need to be kept warm. In this example, the opening 24 is located at one end of the cup body 20 along the first direction a, and multiple accommodating components 11 can be placed into the heat storage chamber 23 along the first direction a to facilitate the placement and removal of the heat storage device 10. The lid 25 is used to close the opening 24 to keep the heat storage chamber 23 closed, thereby further improving the heat preservation performance of the refrigerator cup 100. In some examples, a sealing ring 26 can be provided between the lid 25 and the cup body 20 to seal the gap between the lid 25 and the cup body 20, thereby reducing heat leakage. In some examples, a cushioning layer 27 may be provided at the end of the refrigerator cup 100 away from the opening 24. The cushioning layer 27 is used to cushion the heat storage device 10 to reduce the possibility of a hard collision between the heat storage device 10 and the bottom wall of the refrigerator cup 100. In this example, the cushioning layer 27 can be a cushioning structure such as a rubber pad or a sponge pad.

[0063] In some examples, the cup body 20 has a depth direction that is parallel to the first direction a, so as to facilitate the placement of the heat storage device 10 into the cup body 20 along the first direction a.

[0064] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
