Description

Technical Field

[0001] This disclosure relates to the field of daily necessities technology, specifically to a refrigerator cup. Background Technology

[0002] In daily life, some foods and medicines need to be refrigerated, such as breast milk and insulin, which require refrigeration at certain temperatures. Refrigerators are commonly used refrigeration devices, but when people go out and must carry certain foods or medicines that need to be stored at low temperatures, the refrigeration of these foods or medicines becomes a tricky problem.

[0003] Currently, portable refrigerated cups have appeared on the market. These refrigerated cups mainly consist of an outer cup, an inner cup for storing food or medicine, and a lid. A cold insulation layer is set between the inner and outer cups to keep the food or medicine in the inner cup at a low temperature, preventing the food or medicine from spoiling or becoming ineffective.

[0004] For example, CN220229617U discloses a portable refrigerator cup that can reduce temperature differences within a refrigerator cavity. The refrigerator cup in this design includes a cylindrical body with a cylindrical refrigerator cavity coaxial with the body. The height of the refrigerator cavity is greater than the length of any line segment on its horizontal cross-section. An insulation layer is tightly fitted to the outer wall of the refrigerator body, and a refrigeration device is provided to absorb heat from the refrigerator cavity and transfer it to the outside of the refrigerator body. This refrigeration device is electrically powered, and the cup body also includes a control panel, a cooling fan, and a display window.

[0005] For example, CN206187688U discloses a refrigerated cup comprising an outer cup body, an inner liner, and a lid. A sealed cavity is formed between the outer cup body and the inner liner to hold a chemical material packet and a chemical adsorption packet. The chemical material packet contains a substance that can achieve cooling through a chemical endothermic reaction. When the substance in the chemical material packet undergoes a chemical reaction, it absorbs a large amount of heat, which is then used to refrigerate the food or medicine inside the inner liner. This refrigerated cup has a simple structure and requires no electricity.

[0006] While the aforementioned or similar refrigerated cups achieve portability and improve user convenience, their cold-keeping effects vary, and the ability to maintain coldness continuously cannot be guaranteed, thus affecting the user experience. Utility Model Content

[0008] To achieve the above objectives, this disclosure provides a refrigerator cup, comprising:

[0009] The outer cup includes an inner cup wall and an outer cup wall sleeved on the inner cup wall. The gap between the inner cup wall and the outer cup wall forms a first vacuum structure, and the space enclosed by the inner cup wall forms a receiving cavity.

[0010] The cup lid is provided with a second vacuum structure, and the cup lid is used to seal the receiving cavity;

[0011] At least one independently sealed inner cup for containing substances requiring refrigeration, the inner cup being housed within the containing cavity; and

[0012] A refrigerated container, internally filled with a cold-keeping agent; the refrigerated container is disposed in the gap between the inner cup wall and the inner cup and at least surrounds the outer peripheral wall of the inner cup; the refrigerated container is recyclable.

[0013] Preferably, the cup lid includes a connecting part for connecting with the mouth of the outer cup and a sealing cavity, and the lower part of the sealing cavity is provided with a second sealing element for sealing connection with the inner cup wall.

[0014] More preferably, the inner cup wall forms an inclined surface that slopes towards the refrigerator cup, and the second seal has the same inclination angle as the inclined surface. The second seal achieves a seal at the inclined surface through compression deformation; or

[0015] The inner cup wall does not form the inclined surface, and the lower part of the sealing cavity is provided with a number of annular protrusions of the second sealing element along its circumference. The second sealing element achieves sealing at the inner cup wall through extrusion deformation.

[0016] Preferably, the refrigerator body includes several annular structures with openings at both ends, the annular structures are sleeved on the outside of the inner cup, and the annular structures are connected by stacking.

[0017] More preferably, one end of the annular structure has a protrusion and the other end has a notch, and when two adjacent annular structures are stacked, the protrusion of one annular structure is confined in the notch of the other annular structure.

[0018] Preferably, the refrigeration unit includes a plurality of compartments open at one end, wherein the opening of one compartment is detachably connected to the opening of another compartment;

[0019] The two chambers are connected to form a receiving space, which is used to receive one of the inner cups.

[0020] More preferably, half of the compartments have a plurality of engaging blocks along the circumference at the outer wall of the opening;

[0021] The other half of the compartments have circumferential openings on the inner wall of the openings to allow the locking blocks to slide into them;

[0022] The opening is connected to and penetrates the limiting part. When the locking block slides into the opening, rotating one of the compartments can cause the locking block to slide into the limiting part.

[0023] Preferably, the refrigerator body has a first airflow channel along the axial direction on its outer wall to widen the gap between it and the inner cup wall; and / or

[0024] The opening of the chamber is provided with a second airflow channel that connects to the interior of the containment space.

[0031] The technical solution claimed in this disclosure mainly achieves the following beneficial effects:

[0032] 1. In the refrigerated cup structure disclosed herein, the entire inner cup used for storing substances requiring refrigeration is completely surrounded by a refrigeration body. When the inner cup is placed into the receiving cavity of the outer cup, the vacuum layer of the outer cup further insulates the periphery and bottom of the inner cup. When the lid is closed, the hollow structure in the lid further insulates the top of the inner cup. Therefore, the inner cup is simultaneously subjected to triple insulation from the refrigeration body, the vacuum layer of the outer cup, and the vacuum layer of the lid, improving the refrigeration efficiency of the contents and extending the refrigeration storage time.

[0033] 2. The space inside the container cavity is sealed simultaneously by the connecting part on the lid and the second sealing element, which further isolates the heat exchange between the inside and outside of the refrigerator cup and improves the cold preservation and heat insulation effect.

[0034] 3. The vacuum component in the lid can further create a vacuum in the outer cup cavity and the space formed by the refrigerator body after the inner cup, refrigerator body, and outer cup are assembled. This isolates external heat from entering the cup, increases the cold insulation effect, improves the cold insulation efficiency of the contents in the inner cup, and extends its storage time.

Detailed Implementation

[0049] To make the objectives, technical solutions, and beneficial effects of the embodiments in this disclosure clearer, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0050] Example 1

[0051] This embodiment provides a refrigerator cup, such as Figure 1-9 As shown, it mainly consists of an outer cup 1, an inner cup 6, and a lid 5. The inner cup 6 is used to store food or medicine that needs to be stored at low temperatures, such as breast milk.

[0052] The outer cup 1 includes an inner cup wall 2 and an outer cup wall 3 fitted onto the inner cup wall 2. The gap between the inner cup wall 2 and the outer cup wall 3 is configured as a first vacuum structure, and the space enclosed by the inner cup wall 2 forms a receiving cavity 4. The cup lid 5 is provided with a second vacuum structure and is used to seal the receiving cavity 4.

[0053] The refrigerated cup in this embodiment has at least one independently sealed inner cup 6, which is housed in the receiving cavity 4, and its peripheral walls and bottom are surrounded by the vacuum structure of the outer cup 1.

[0054] Furthermore, the refrigerated cup in this embodiment also includes a recyclable refrigerated body 7. This refrigerated body 7 can be exemplarily configured as a double-layer structure, filled internally with a cold-keeping agent, such as a soluble polymer whose main components are low-polymerization sodium polyacrylate, polyvinyl alcohol, or polyacrylamide. Additionally, a partition or grid can be provided inside the refrigerated body to make the cold-keeping agent more evenly distributed while also enhancing the mechanical strength of the refrigerated body. The refrigerated body 7 is disposed in the gap between the inner cup wall 2 and the inner cup 6 and at least surrounds the outer peripheral wall of the inner cup 6. The refrigerated body 7 is in a clearance fit with the inner cup wall 2, and the inner cup 6 is also in a clearance fit with the refrigerated body 7. Both the refrigerated body 7 and the inner cup 6 can be removed from the receiving cavity 4.

[0055] In the refrigerated cup structure of this embodiment, the inner cup 6, used to store substances requiring refrigeration, is surrounded by the refrigeration body 7. When the inner cup 6 is placed into the receiving cavity 4 of the outer cup 1, the vacuum layer of the outer cup 1 provides further heat insulation to the periphery and bottom of the inner cup 6. When the lid 5 is closed, the hollow structure in the lid 5 provides further heat insulation to the top of the inner cup 6. Therefore, the inner cup 6 is simultaneously subjected to triple heat insulation and cold preservation effects from the refrigeration body 7, the vacuum layer of the outer cup 1, and the vacuum layer of the lid 5, improving the cold preservation efficiency of the substances inside and extending the refrigerated storage time.

[0056] In a preferred embodiment, such as Figure 9 As shown, the cup lid 5 includes a vacuum assembly for creating a vacuum environment inside the refrigerated cup, a power supply module 10, a control module 11, a display window 12, and a temperature sensing module 13. Exemplarily, the vacuum assembly consists of a vacuum pump 8 and a vacuum control valve 9 connected to the vacuum pump 8. The vacuum control valve 9 can be configured to connect to a button, allowing the user to control the start or de-vacuuming of the vacuum pump 8 by pressing the button. After the cup lid 5 is closed, the vacuum pump 8 connects to the receiving cavity 4 to extract air from the receiving cavity 4, creating a vacuum environment within it and preventing external heat from entering the cup, thus enhancing the heat insulation effect. Alternatively, an independent one-way valve can be selected to connect the receiving cavity 4 to the outside world, thereby de-vacuuming the receiving cavity 4.

[0057] The power supply module 10 (e.g., a rechargeable battery) supplies power to all electrical devices within the cup lid 5, and the temperature sensing module 13 (e.g., a temperature probe) detects the temperature of the containing cavity 4. The control module 11 (e.g., a PCB control board) is connected to the vacuum assembly, the display window 12 (screen), and the temperature sensing module 13. The display window 12 displays at least the temperature and vacuum level of the containing cavity 4 for user viewing. In this embodiment, the temperature sensing module 13, control module 11, and vacuum assembly are housed within the internal space of the cup lid 5 by compression. Alternatively, in another exemplary structure, the vacuum pump 8 may not be located inside the cup lid 5; the refrigerated cup can create a vacuum environment within it by connecting to an external vacuum device via a vacuum control valve 9.

[0058] In the exemplary structure, reference Figure 4 The second vacuum structure in the cup lid 5 includes a first vacuum region 14 and a second vacuum region 15. The first vacuum region 14 is arranged around the peripheral wall of the cup lid 5 and is located above the connection between the cup lid 5 and the outer cup 1. The second vacuum region 15 is configured such that when the receiving cavity 4 is sealed by the cup lid 5, the second vacuum region 15 is located directly above the top of the receiving cavity 4. The position of the second vacuum region 15 is lower than the first vacuum region 14, and the area of ​​the second vacuum region 15 is set as large as possible to reduce the gap between the vacuum region and the vacuum layer of the cup body, preventing external heat from entering the cup. Preferably, the bottom of the cup lid 5 may be provided with a first sealing element 16 for further sealing the second vacuum region inside the cup lid 5. A filter sheet is also provided below the second vacuum region 15. The filter sheet is used to filter the air in the receiving cavity during the vacuuming process to minimize the intake of dust and other impurities inside the cup into the vacuum pump. The double vacuum structure in the cup lid 5 further enhances the heat insulation effect.

[0059] In this embodiment, the vacuum component in the cup lid 5 can further create a vacuum in the accommodating cavity 4 of the outer cup 1 and the accommodating space 21 formed by the accommodating body 7 after the inner cup 6, the refrigeration body 7, and the outer cup 1 are assembled, thereby increasing the cold insulation effect, improving the cold insulation efficiency of the substance in the inner cup, and extending its storage time.

[0060] In one exemplary structure, the cup lid 5 is connected to the outer cup 1 by a thread; or, a flexible sealing structure (such as a silicone ring, not shown in the figure) can be provided along the circumference at the lower part of the cup lid 5. The diameter of the sealing structure is larger than the inner diameter of the cup opening of the outer cup 1. After the sealing structure enters the cup opening of the outer cup 1, it achieves the sealing of the receiving cavity 4 by extrusion deformation at the inner wall of the cup opening of the outer cup 1.

[0061] In a preferred configuration, the connection between the inner cup wall 2 and the outer cup wall 3 at the cup opening of the outer cup 1 also forms a vacuum region 27, which communicates with the first vacuum structure. Exemplarily, the cup lid 5 includes a connecting portion 28 for threaded or compression-sealed connection with the outer cup 1, and a closed cavity 29 for accommodating the aforementioned vacuum components, power supply module 10, control module 11, and temperature sensing module 13.

[0062] In another, more preferred configuration, the lid 5 and the inner cup wall 2 also form a sealing connection. For example, as shown... Figure 10-11 As shown, the inner cup wall 2 forms a slope 30 inclined towards the center of the refrigerated cup below the vacuum region 27. The lower part of the sealed cavity 29 has a second sealing element 31 that is sealed to the slope 30. The second sealing element 31 has an inclination angle adapted to the slope 30, and the second sealing element 31 achieves a seal at the slope 30 through compression deformation. The cone-shaped sealing structure between the inner cup wall 2 and the cup lid 5 seals the receiving cavity 4 while facilitating the opening of the cup lid 5.

[0063] In another exemplary structure, the inner cup wall 2 does not have a slope, and the lower part of the closed cavity 29 of the cup lid 5 is provided with several annular protrusions of the second sealing element 31 along its circumference. In this structure, the second sealing element 31 directly achieves a locking seal at the inner cup wall 2 through compression deformation, thereby sealing the receiving cavity 4. Of course, the conical sealing connection structure can also be combined with the locking sealing connection structure; for example, the locking sealing structure can be placed below the conical sealing structure.

[0064] In this embodiment, the second sealing element 31 can be made of an elastic material, such as silicone. By simultaneously sealing the space inside the receiving cavity 4 through the connecting part 28 on the cup lid 5 and the second sealing element 31, heat exchange between the inside and outside of the refrigerator cup is further isolated, improving the cold preservation and heat insulation effect.

[0065] In an exemplary structure, such as Figure 2-3 As shown, the refrigerator body 7 includes several annular structures 17 with openings at both ends. The annular structures 17 are fitted onto the outside of the inner cup 6, and the annular structures 17 are connected by stacking. For example, a protrusion 18 may be provided at one end of the annular structure 17, and a notch 19 may be provided at the other end. When two adjacent annular structures 17 are stacked, the protrusion 18 of one annular structure 17 is confined in the notch 19 of the other annular structure 17.

[0066] The process of using the refrigerator cup in this embodiment is as follows:

[0067] When it is necessary to refrigerate and preserve the substance, put the substance to be refrigerated into the inner cup 6 and seal the inner cup 6. Then put the sealed inner cup 6 into the receiving cavity 4 of the outer cup 1.

[0068] A ring structure 17, which has been pre-treated with low-temperature refrigeration (such as pre-refrigeration in a refrigerator), is placed on the outer shell of the inner cup 6 until the ring structure 17 is stacked to completely surround the peripheral wall of the inner cup 6. The refrigeration agent inside the ring structure 17 keeps the refrigerated substance at a low temperature.

[0069] The outer cup 1 is sealed by the cup lid 5. After the cup lid 5 is tightly fixed, the vacuum pump 8 is turned on to extract the air from the receiving cavity 4 and the refrigerator body 7, forming a vacuum environment inside the refrigerator cup.

[0070] Example 2

[0071] This embodiment provides a refrigerator cup, such as Figure 1-9 As shown, it mainly consists of an outer cup 1, an inner cup 6, and a lid 5. The inner cup 6 is used to store food or medicine that needs to be stored at low temperatures, such as breast milk.

[0072] The outer cup 1 includes an inner cup wall 2 and an outer cup wall 3 fitted onto the inner cup wall 2. The gap between the inner cup wall 2 and the outer cup wall 3 is configured as a first vacuum structure, and the space enclosed by the inner cup wall 2 forms a receiving cavity 4. The cup lid 5 is provided with a second vacuum structure and is used to seal the receiving cavity 4.

[0073] In this embodiment, the refrigerated cup has at least one independently sealed inner cup 6, which is housed in the receiving cavity 4, and its periphery and bottom are surrounded by the vacuum structure of the outer cup 1.

[0074] Furthermore, the refrigerated cup in this embodiment also includes a recyclable refrigerated body 7. This refrigerated body 7 can be exemplarily configured as a double-layer structure, filled internally with a cold-keeping agent, such as a soluble polymer whose main components are low-polymerization sodium polyacrylate, polyvinyl alcohol, or polyacrylamide. Additionally, a partition or grid can be provided inside the refrigerated body to make the cold-keeping agent more evenly distributed while also enhancing the mechanical strength of the refrigerated body. The refrigerated body 7 is disposed in the gap between the inner cup wall 2 and the inner cup 6 and at least surrounds the outer peripheral wall of the inner cup 6. The refrigerated body 7 is in a clearance fit with the inner cup wall 2, and the inner cup 6 is also in a clearance fit with the refrigerated body 7. Both the refrigerated body 7 and the inner cup 6 can be removed from the receiving cavity 4.

[0075] In the refrigerated cup structure of this embodiment, the inner cup 6, used to store substances requiring refrigeration, is surrounded by the refrigeration body 7. When the inner cup 6 is placed into the receiving cavity 4 of the outer cup 1, the vacuum layer of the outer cup 1 provides further heat insulation to the periphery and bottom of the inner cup 6. When the lid 5 is closed, the hollow structure in the lid 5 provides further heat insulation to the top of the inner cup 6. Therefore, the inner cup 6 is simultaneously subjected to triple heat insulation and cold preservation effects from the refrigeration body 7, the vacuum layer of the outer cup 1, and the vacuum layer of the lid 5, improving the cold preservation efficiency of the substances inside and extending the refrigerated storage time.

[0076] In a preferred embodiment, such as Figure 9 As shown, the cup lid 5 includes a vacuum assembly for creating a vacuum environment inside the refrigerated cup, a power supply module 10, a control module 11, a display window 12, and a temperature sensing module 13. Exemplarily, the vacuum assembly consists of a vacuum pump 8 and a vacuum control valve 9 connected to the vacuum pump 8. The vacuum control valve 9 can be configured to connect to a button, allowing the user to control the start or de-vacuuming of the vacuum pump 8 by pressing the button. After the cup lid 5 is closed, the vacuum pump 8 connects to the receiving cavity 4 to extract air from the receiving cavity 4, creating a vacuum environment within the receiving cavity 4 and enhancing the heat insulation effect. Alternatively, an independent one-way valve can be selected, allowing the receiving cavity 4 to connect to the outside world and thus de-vacuuming the receiving cavity 4.

[0077] The power supply module 10 (e.g., a rechargeable battery) supplies power to all electrical devices within the cup lid 5, and the temperature sensing module 13 (e.g., a temperature probe) detects the temperature of the containing cavity 4. The control module 11 (e.g., a PCB control board) is connected to the vacuum assembly, the display window 12, and the temperature sensing module 13. The display window 12 displays at least the temperature and vacuum level of the containing cavity 4 for user viewing. In this embodiment, the temperature sensing module 13, control module 11, and vacuum assembly are housed within the internal space of the cup lid 5 by compression. Alternatively, in another exemplary structure, the vacuum pump 8 may not be located inside the cup lid 5; the refrigerated cup can create a vacuum environment within it by connecting to an external vacuum device via a vacuum control valve 9.

[0078] In the exemplary structure, reference Figure 4 The second vacuum structure in the cup lid 5 includes a first vacuum region 14 and a second vacuum region 15. The first vacuum region 14 is arranged around the peripheral wall of the cup lid 5 and is located above the connection between the cup lid 5 and the outer cup 1. The second vacuum region 15 is configured such that when the receiving cavity 4 is sealed by the cup lid 5, the second vacuum region 15 is located directly above the top of the receiving cavity 4. The position of the second vacuum region 15 is lower than the first vacuum region 14, and the area of ​​the second vacuum region 15 is set as large as possible to reduce the gap between the vacuum region and the vacuum layer of the cup body, preventing external heat from entering the cup. Preferably, the bottom of the cup lid 5 may be provided with a first sealing element 16 for further sealing the second vacuum region inside the cup lid 5. A filter sheet is also provided below the second vacuum region 15. The filter sheet is used to filter the air in the receiving cavity during the vacuuming process to minimize the intake of dust and other impurities inside the cup into the vacuum pump. The double vacuum structure in the cup lid 5 further enhances the heat insulation effect.

[0079] In this embodiment, the vacuum component in the cup lid 5 can further create a vacuum in the accommodating cavity 4 of the outer cup 1 and the accommodating space 21 formed by the accommodating body 7 after the inner cup 6, the refrigeration body 7, and the outer cup 1 are assembled, thus isolating external heat from entering the cup, increasing the cold insulation effect, improving the cold insulation efficiency of the substance in the inner cup, and extending its storage time.

[0080] In one exemplary structure, the cup lid 5 is connected to the outer cup 1 by a thread; or, a flexible sealing structure (such as a silicone ring, not shown in the figure) can be provided along the circumference at the lower part of the cup lid 5. The diameter of the sealing structure is larger than the inner diameter of the cup opening of the outer cup 1. After the sealing structure enters the cup opening of the outer cup 1, it achieves the sealing of the receiving cavity 4 by extrusion deformation at the inner wall of the cup opening of the outer cup 1.

[0081] In a preferred configuration, the connection between the inner cup wall 2 and the outer cup wall 3 at the cup opening of the outer cup 1 also forms a vacuum region 27, which communicates with the first vacuum structure. Exemplarily, the cup lid 5 includes a connecting portion 28 for threaded or compression-sealed connection with the outer cup 1, and a closed cavity 29 for accommodating the aforementioned vacuum components, power supply module 10, control module 11, and temperature sensing module 13.

[0082] In another, more preferred configuration, the lid 5 and the inner cup wall 2 also form a sealing connection. For example, as shown... Figure 10-11 As shown, the inner cup wall 2 forms a slope 30 inclined towards the center of the refrigerated cup below the vacuum region 27. The lower part of the sealed cavity 29 has a second sealing element 31 that is sealed to the slope 30. The second sealing element 31 has an inclination angle adapted to the slope 30, and the second sealing element 31 achieves a seal at the slope 30 through compression deformation. The cone-shaped sealing structure between the inner cup wall 2 and the cup lid 5 seals the receiving cavity 4 while facilitating the opening of the cup lid 5.

[0083] In another exemplary structure, the inner cup wall 2 does not have a slope, and the lower part of the closed cavity 29 of the cup lid 5 is provided with several annular protrusions of the second sealing element 31 along its circumference. In this structure, the second sealing element 31 directly achieves a locking seal at the inner cup wall 2 through compression deformation, thereby sealing the receiving cavity 4. Of course, the conical sealing connection structure can also be combined with the locking sealing connection structure; for example, the locking sealing structure can be placed below the conical sealing structure.

[0084] In this embodiment, the second sealing element 31 can be made of an elastic material, such as silicone. The connecting portion 28 on the lid 5 and the second sealing element 31 simultaneously seal the space within the receiving cavity 4, further isolating heat exchange between the inside and outside of the refrigerator cup and improving the cold-keeping and heat-insulating effect. In a preferred embodiment, such as... Figure 4-8As shown, the refrigerator body 7 includes a plurality of compartments 20 with openings at one end. The opening of one compartment 20 is detachably connected to the opening of another compartment 20. When two compartments 20 are connected, they form a receiving space 21. Each receiving space 21 is used to receive an inner cup 6. The inner cup 6 is gap-connected to the inner wall of the compartment 20. The side walls, top, and bottom of the inner cup 6 are surrounded by the refrigerator body.

[0085] In the exemplary structure, half of the compartments 20 have a plurality of engaging blocks 22 along the circumference of the outer wall of the opening; the other half of the compartments 20 have an opening 23 along the circumference of the inner wall of the opening, allowing the engaging blocks 22 to slide into it. The opening 23 is connected to and communicates with a limiting part 24. When the engaging block 22 slides into the opening 23, rotating one of the compartments 20 can cause the engaging block 22 to slide into the limiting part 24, thereby fixing the two compartments 20 together.

[0086] Since the connection between the refrigerator body 7 and the inner cup wall 2, as well as between the inner cup 6 and the refrigerator body 7, is a gap connection, in order for the vacuum assembly to smoothly extract air from the receiving cavity 4 during operation, a first airflow channel 25 can be provided axially on the outer wall of the refrigerator body 7 to widen the gap between it and the inner cup wall 2. In an exemplary structure, several concave surfaces / grooves can be provided on the outer wall of the compartment to serve as the first airflow channel 25. Furthermore, a second airflow channel 26 connecting to the interior of the receiving space 21 can also be provided at the opening of the compartment 20, so that the air therein can also be smoothly extracted to form a vacuum environment. Any structure that can form a connection to the interior of the receiving space 21 at the opening after the two compartments 20 are connected can serve as the second airflow channel 26, which will not be elaborated further here.

[0087] The process of using the refrigerator cup in this embodiment is as follows:

[0088] When a substance needs to be refrigerated, place the substance into the inner cup 6 and seal the inner cup 6.

[0089] Place the sealed inner cup 6 into a compartment 20 that has been pre-treated at low temperature (e.g., pre-refrigerated in a refrigerator), cover it with another compartment that has also been pre-treated at low temperature, rotate one of the compartments so that the locking block of one compartment slides into the limiting part of the other compartment, so that the two compartments are fixedly connected at the opening.

[0090] The inner cup, which is entirely surrounded by two chambers, is placed into the receiving cavity 4 of the outer cup 1;

[0091] The outer cup 1 is sealed by the cup lid 5. After the cup lid 5 is tightly fixed, the vacuum pump 8 is turned on to extract the air from the receiving cavity 4 and the refrigerator body 7, forming a vacuum environment inside the refrigerator cup.
