DETAILED DESCRIPTION

[0034] The core of this utility model is to provide a fresh-keeping cup that can keep the fresh-keeping objects in the cup fresh for a longer time, and can monitor the temperature in the cup in real time to ensure that the fresh-keeping objects are at an optimal fresh-keeping temperature, so that users can feel more at ease and improve user experience.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The utility model provides a fresh-keeping cup. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, Figure 1 This is a schematic diagram of the outer shell and inner liner of an embodiment of a fresh-keeping cup provided by the utility model. Figure 2 This is a schematic diagram of the inner container of an embodiment of a fresh-keeping cup provided by the present invention. Figure 3This is an overall exploded view of an embodiment of a fresh-keeping cup provided by the present invention. The fresh-keeping cup comprises a heat-insulating outer shell 1 having an internal cavity 11 and a cup mouth 12. The cup mouth 12 is the opening portion of the internal cavity 11.

[0037] The inner liner 2 is detachably mounted in the inner cavity 11. Specifically, the inner liner 2 can be mounted in the inner cavity 11 via the cup opening 12. The inner liner 2 and the heat-insulating outer shell 1 may not be fixed together. The inner liner 2 can be taken out of or put into the inner cavity 11 of the heat-insulating outer shell 1. The heat-insulating outer shell 1 can isolate its inner cavity 11 from the external environment of the fresh-keeping cup, thereby avoiding heat exchange between the inside and outside of the fresh-keeping cup to a greater extent, thereby keeping the temperature inside the fresh-keeping cup longer and extending the shelf life. Figure 3 It can be seen that the inner container 2 has a first accommodating chamber 21 and a second accommodating chamber 22. The first accommodating chamber 21 is used to place a heat storage material, and the second accommodating chamber 22 is used to place a fresh-keeping object. This heat storage material is a new type of chemical material that can store thermal energy. It undergoes a phase change at a specific temperature (such as a phase change temperature) and absorbs or releases heat. It can be used to control the temperature of the surrounding environment or to store thermal energy. It stores heat or cold and releases it when needed to keep the fresh-keeping object in a suitable target temperature range, thereby achieving fresh-keeping. Taking the refrigerated preservation method as an example, the inner liner 2 can be taken out first and placed in a freezer to freeze the heat storage material therein, so that a large amount of cold energy can be stored in the heat storage material. Then, the inner liner 2 in this state is put back into the fresh-keeping cup, and the cold energy can be continuously released to the fresh-keeping object, thereby achieving the preservation of the fresh-keeping object. The situation where fresh-keeping at a higher temperature is required is similar, that is, a certain amount of warm heat can be stored in the heat storage material, so that the food can be kept warm and the user can take it out and eat it at any time. The specific situation is as in the above example and will not be repeated here.

[0038] The cup cover 13 is provided on the cup mouth 12 to seal the fresh-keeping cup. After the inner container and the fresh-keeping object are placed in the fresh-keeping cup, the cup cover 13 can be closed to isolate the internal environment of the fresh-keeping cup from the external environment and prevent heat or cold from being lost. The cup cover 13 and the cup mouth 12 can be sealed and fixed by a threaded connection.

[0039] The fresh-keeping cup also includes: a temperature detection component 3 and a display component 4 connected in communication, Figure 4 , Figure 4Schematic diagram of the composition of the temperature detection component and the display component. The temperature detection component 3 may include a first temperature sensor 31 for detecting the temperature of the second accommodating cavity 22. The display component 4 has a first temperature display module 41 for displaying the first temperature detected by the first temperature sensor 31. The first temperature display module 41 is arranged to face the outside of the fresh-keeping cup so that it is convenient for the user to see. In this case, the first temperature detected by the first temperature sensor 31 can be directly transmitted to the first temperature display module 41 for display. The user can directly see the temperature of the second accommodating cavity 22 from the outside of the fresh-keeping cup to more clearly understand the environment in which the fresh-keeping object is located at this time. If the temperature is not suitable, it is convenient to take corresponding measures in time to deal with it, so that the temperature inside the fresh-keeping cup can be effectively controlled. Specifically, the first The temperature sensor 31 is preferably installed on the inner side of the cup cover 13, so that the first temperature sensor 31 is located in the upper space of the internal environment of the inner liner 2. Temperature measurement from here will be faster, more convenient and relatively accurate. Compared with setting the first temperature sensor 41 in the inner liner 2, setting the first temperature sensor 41 in the cup cover 13 reduces the manufacturing difficulty. In some embodiments, the first temperature sensor 31 can also be installed in the inner liner 2, and this embodiment does not limit this. In addition, the display component 4 can be preferably installed on the cup cover 13, and the temperature data can be observed from the outer side of the cup cover 13, which improves the convenience of use. In some embodiments, the display component 4 can also be installed on the insulation shell, and a certain position of the insulation shell can be selected for installation according to actual needs. This embodiment does not limit this.

[0040] It can be seen from the above technical solution that in the embodiment of the above-mentioned fresh-keeping cup provided by the present invention, since it includes an inner liner 2 detachably mounted on the internal cavity 11 of the heat-insulating shell 1, the inner liner 2 has a first accommodating cavity 21 and a second accommodating cavity 22. The first accommodating cavity 21 is used to place a heat storage material, and the second accommodating cavity 22 is used to place a fresh-keeping object. Therefore, the inner liner 2 can be taken out and placed in a freezing device to freeze the heat storage material therein, and then the inner liner 2 can be put back into the heat-insulating shell 1, and the fresh-keeping object can be placed in the second accommodating cavity 22 of the inner liner 2, and the heat storage material can be used to refrigerate the fresh-keeping object, and the heat-insulating shell 1 can be used to avoid The cold air diffuses to the outside, so the preservation cup can be used to preserve the objects in the cup for a longer time. In addition, since it also includes a temperature detection component 3 and a display component 4 that are communicatively connected, the temperature detection component 3 includes a first temperature sensor 31 for detecting the temperature of the second accommodating cavity 22, and the display component 4 has a first temperature display module 41 for displaying the first temperature detected by the first temperature sensor 31. Therefore, the temperature in the cup can be monitored in real time to ensure that the objects are at an optimal preservation temperature. In this way, the user can understand the temperature data in the preservation cup in real time from the outside of the preservation cup, which makes the user more assured and improves the user experience.

[0041] In a specific embodiment of the above-mentioned fresh-keeping cup, reference Figure 5 , Figure 5 Schematic diagram of the connection between the control component, the temperature detection component and the display component. Based on the above embodiment, the temperature detection component 3 may further include a second temperature sensor 32 for detecting the external ambient temperature. The second temperature sensor 32 may be provided on the heat-insulating shell 1. Of course, in some embodiments, it may also be provided on the cup cover 13. As long as it can accurately detect the external ambient temperature of the fresh-keeping cup, there is no limitation here.

[0042] The display assembly 4 may further include a second temperature display module 42 for displaying the second temperature detected by the second temperature sensor 32. In this case, the user may also be aware of the external ambient temperature of the fresh-keeping cup, so as to facilitate self-assessment of whether the current ambient temperature conditions are suitable for placing breast milk in the fresh-keeping cup for preservation and to estimate the preservation effect. Furthermore, the second temperature sensor 32 and the second temperature display module 42 may preferably be arranged on the cup cover 13, which can be closer to other components, thereby facilitating communication connection, saving line costs, and making the overall structure more compact. When the user looks at the fresh-keeping cup, the line of sight is from top to bottom, which makes it easier to discover the second temperature. Of course, other locations may also be selected according to actual needs, such as the second temperature sensor 42 and the second temperature display module 42 being installed on the heat-insulating shell 1, which is not limited here.

[0043] Continue to refer Figure 5The fresh-keeping cup may further include a control component 5, which is communicatively connected to the first temperature sensor 31, the second temperature sensor 32, the first temperature display module 41, and the second temperature display module 42. The control component 5 includes a calculation module 51 for calculating the fresh-keeping period based on the first and second temperatures. The display component 4 also includes a fresh-keeping period display module 43 for displaying the fresh-keeping period. The fresh-keeping period display module 43 is communicatively connected to the calculation module 51. In this case, the calculation module 51 can simultaneously communicate with the first temperature sensor 31 and the second temperature sensor 32 to receive real-time data on the first and second temperatures. The calculation module 51 also communicates with the first and second temperature display modules 41 and 42 to transmit the data on the first and second temperatures, respectively. In this way, the first and second temperature data display modules 41 and 42 can display the data on the first and second temperatures, respectively. The calculation module 51 can also be communicatively connected to the fresh-keeping period display module 43 to directly display the calculated fresh-keeping period to the user, so that the user can understand the fresh-keeping period. For example, during the preservation process of milk, the cold air inside the inner liner 2 will inevitably exchange heat with the outside. Therefore, the refrigerated environment provided by the inner liner 2 to the milk will have the problem of gradually rising temperature. Especially when the external environment temperature of the preservation cup is high, the heat exchange causes a serious loss of cold energy, and the temperature inside the preservation cup rises. The high temperature easily leads to the breeding of bacteria. In order to avoid this problem, this embodiment can immediately collect the first temperature and the second temperature after the milk is placed in the preservation cup, and transmit them to the calculation module 51. The calculation module 51 can calculate the temperature difference between the two, calculate the rate of natural heat loss, and then calculate the time required to reach the preservation threshold temperature from the first temperature. This is the shelf life. For example, if the shelf life is 7 hours, the shelf life will be transmitted to the shelf life display module 43 and displayed to the user. At this time, the user can immediately know the shelf life. If the user knows that he cannot feed the milk to the baby within the current shelf life, he should take relevant measures, such as finding another place to place the shelf life cup in an environment with a lower temperature to avoid bacterial growth and deterioration. When it arrives at a new environment, the calculation module 51 can recalculate according to the second temperature of the external environment of the shelf life cup that is newly obtained, and display a new shelf life. It can be seen that this allows the user to understand the shelf life from the beginning, better avoid deterioration, and ensure the quality of the preserved object.

[0044] In another specific embodiment of the above-mentioned fresh-keeping cup, based on the above-mentioned specific embodiment, continue to refer to Figure 5 , further comprising a pressure sensing component 6 in communication with the control component 5, and the pressure sensing component 6 is disposed at a position where the cup cover 13 contacts the heat-insulating shell 1, and the pressure sensing component 6 is used to detect the pressure exerted on the cup cover 13;

[0045] The control component 5 further includes a timing module 52, which is in communication with the control component 5 and is configured to start counting the freshness preservation duration when the pressure reaches a predetermined threshold value, wherein the predetermined threshold value corresponds to the pressure when the cup lid is tightened, indicating that the cup lid is in a tightened state;

[0046] The display component 4 further includes a freshness-keeping duration display module 44 for displaying the freshness-keeping duration. The freshness-keeping duration display module 44 is in communication with the timing module 52 .

[0047] In this case, the timer can be automatically counted after the fresh-keeping object is placed, and the actual storage time (i.e., the fresh-keeping duration) can be displayed, so that the user can know the actual storage time more clearly. If the fresh-keeping duration exceeds a specific time, the user can throw away the fresh-keeping object if he thinks it has deteriorated after this time. It can be seen that this provides a more accurate basis for whether to keep the fresh-keeping object.

[0048] In another embodiment of the fresh-keeping cup, based on the above embodiment, an alarm component 7 in communication with the control component 5 may be further included. The alarm component 7 is configured to generate an alarm signal or a related reminder signal, such as a buzzer, voice prompt, or music, etc., when the difference between the fresh-keeping duration and the fresh-keeping expiration date is less than a preset threshold. For example, when the calculated fresh-keeping expiration date is 7 hours, if the actual fresh-keeping duration measured by the timing module reaches 5 hours, the difference between the two is 2 hours, and the preset threshold is 2 hours, an alarm signal may be generated to inform the user of the risk of the fresh-keeping item spoiling within 2 hours. This allows the user to take timely action to ensure the safety and health of the fresh-keeping item. Of course, this preset threshold can be input by the user and can be set to a larger or smaller value according to the user's needs. It can also be written into the control component 5 for direct user access. As can be seen, the fresh-keeping cup provided by this embodiment is more intelligent, allowing the user to know the accurate fresh-keeping time without having to calculate the time themselves, further improving the user experience.

[0049] Continue to refer Figure 2In a preferred embodiment of the aforementioned fresh-keeping cup, based on any of the four aforementioned embodiments, the inner liner 2 may include an inner barrel 23 and an outer barrel 24. In the radial direction (radial direction of the cylindrical barrel), the inner barrel 23 and the outer barrel 24 separate an annular, sealed first chamber 21. The first chamber 21 is used to hold a heat storage material. The inner barrel 22 includes a second chamber 22 for holding the fresh-keeping object. This allows for the release of cooling or heating to the second chamber 22 in a circumferential direction, ensuring a uniform temperature in the circumferential direction and ensuring a fresh-keeping effect. In this embodiment, the insulating outer shell 1, the inner barrel 23, and the outer barrel 24 are all cylindrical. In some embodiments, the insulating outer shell 1, the inner barrel 23, and the outer barrel 24 are not limited to cylindrical barrels and may also have a barrel-shaped cross-section with a triangular, quadrilateral, pentagonal, or other shape, but this is not a limitation of the present invention. In addition, the bottom walls of the inner liner barrel 23 and the outer liner barrel 24 can also be separated to fill the bottom of the inner liner 2 with heat storage material, rather than only filling the interlayer in the circumferential direction of the inner liner 2 with heat storage material.

[0050] refer to Figure 6 , Figure 6This is an exploded view of the inner liner. The contact area between the inner barrel 23 of the inner liner and the outer barrel 24 of the inner liner is preferably provided with a sealing ring 25. The sealing ring 25 matches the first accommodating cavity 21 between the inner barrel 23 of the inner liner and the outer barrel 24 of the inner liner, and is close to the cup cover 13, and / or the end of the inner liner 2 close to the cup cover 13 extends to form a covering ring 231. The covering ring 231 covers the first accommodating cavity 21 between the inner barrel 23 of the inner liner and the outer barrel 24 of the inner liner. In this way, when the inner barrel 23 of the inner liner and the outer barrel 24 of the inner liner are put together, it is possible to ensure that the contact area between the two has better sealing performance, better isolate the first accommodating cavity 21 and the external environment of the fresh-keeping cup, so that the heat inside the first accommodating cavity 21 is not easily exchanged with the external environment of the fresh-keeping cup, so that the heat of the internal heat storage material is released to a greater extent to the fresh-keeping object placed inside the inner liner 2, thereby improving the fresh-keeping effect. The heat storage material can preferably be blue ice, which is a An efficient cold storage carrier or heat storage carrier, blue ice is an excellent ice source after refrigeration, and there is also hot and cold blue ice, which can be used as a heat source after heating. Its advantage is that it does not produce water or other substances during use, and can be used an unlimited number of times. When the fresh-keeping cup is used to store milk, the inner liner can be taken out and placed in a freezing device to freeze the blue ice therein, and then the inner liner is put back into the fresh-keeping cup, and then milk and other foods that need to be preserved are put into the inner liner for preservation. When the fresh-keeping cup is used to store meals and other objects that require a warm environment, the inner liner can be taken out and placed in a heating device first, and the blue ice therein is heated to a certain temperature so that enough high-temperature heat is accumulated therein, and then the inner liner is put back into the fresh-keeping cup, and then the meal is put into the inner liner. In this way, the blue ice can continuously release high-temperature heat to the meal to maintain its warm state. Within the specified period, the user can take the warm meal at any time without reheating. The use of this solution of placing blue ice in the inner liner can make the fresh-keeping cup have more functions, and the cold storage or heat storage of the blue ice can be flexibly adjusted according to the required fresh-keeping temperature and fresh-keeping time. Furthermore, in order to improve the convenience of taking out and putting the inner liner into the fresh-keeping cup, the end of the inner liner 2 close to the cup cover 13 can also be preferably connected to a liner handle 26, so that the user can very conveniently carry this liner handle 26 to take the inner liner out or put it in, which can effectively prevent the user's hand from being too close to the inner liner and causing ice injury or burns, further improving the safety of the fresh-keeping cup. Of course, the shape of this liner handle 26 can be set to an arch, a convex shape or any other suitable shape, which is not limited here. Preferably, the surface of the liner handle 26 is flush with the inner barrel 23 of the inner liner or does not protrude from the inner barrel 23 of the inner liner, so as to ensure better sealing properties.

[0051] In another preferred embodiment of the above-mentioned fresh-keeping cup, the heat-insulating shell 1 can be a double-layer vacuum heat-insulating shell. Figure 3The insulating outer shell 1 includes an insulating outer layer 14 and an insulating inner layer 15. Both layers can be made of stainless steel and together form a vacuum interlayer. This vacuum state eliminates heat conduction, thereby significantly reducing the loss of heat from the fresh-keeping cup to the external environment. This prevents both internal cooling and heat loss. Of course, the material can be replaced with other insulating materials as needed, such as replacing stainless steel with glass, but this is not a limitation.

[0052] Preferably, the heat-insulating outer shell 1 may have a cup bottom 8 disposed opposite the cup opening 11, the cup opening 11 being no smaller than the cup bottom 8, and the outer periphery of the inner liner 2 matching the inner periphery of the heat-insulating outer shell 1. The above-mentioned dimensioning facilitates the insertion and removal of the inner liner 2 from the heat-insulating outer shell 1.

[0053] Preferably, the capacity of the above-mentioned insulation shell 1 can be 1L to 3L, such as 1L, 1.5L, 2L, 2.5L, 3L, etc., preferably 2L to 3L. The capacity of the inner liner 2 is smaller than the capacity of the insulation shell 1. The larger capacity inner liner is more in line with the user's preservation needs.

[0054] In addition, continue to refer to Figure 3 The bottom of the fresh-keeping cup can also include a cup body bottom cover 9, which is the bottom of the fresh-keeping cup itself exposed to the outside, and the above-mentioned cup bottom 8 is the bottom of the heat-insulating shell 1, so it is located inside the fresh-keeping cup. Generally, this cup bottom 8 cannot be seen from the outside, and the above-mentioned cup cover 13 can include a detachably connected cup cover side ring 131, an upper cover 132, and a cup cover handle 133. The cup cover side ring 131 and the upper cover 132 are detachably connected and enclosed to form a accommodating chamber. At least part of the display component 4, the control component 5 and the temperature detection component 3 are arranged in the accommodating chamber. Of course, other accessories can also be added according to actual needs, which is not limited here.

[0055] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
