Such as: the water temperatures required for making tea, making milk powder and making coffee have great difference, and the existing heat preservation device cannot meet various requirements of users.

SUMMERY OF THE UTILITY MODEL

In order to solve at least one of the above technical problems, the present application aims to provide a thermal insulation device.

In order to achieve the above object, according to one embodiment of the present application, there is provided an insulation apparatus including: the cup body is provided with an interlayer and at least one temperature mark, wherein one temperature mark is a reference temperature mark; and a lid configured to fit over the cup; phase transition heat preservation establishes in this interlayer for carry out the heat exchange with the liquid in this cup, this phase transition heat preservation includes at least one phase transition heat preservation portion, and one of them this phase transition heat preservation portion is for referring to phase transition heat preservation portion, and this phase transition heat preservation portion's phase change material's of referring to packing volume and this reference temperature sign satisfy following relation: and in the process that the reference liquid at the liquid level corresponding to the reference temperature mark is cooled to the temperature corresponding to the reference temperature mark, the phase-change material of the reference phase-change heat preservation part is changed from the first phase to the second phase.

The application provides a heat preservation utensil through set up the phase transition heat preservation in the intermediate layer of cup, utilizes the phase transition heat preservation to carry out the heat exchange with the liquid in the cup, changes the temperature of the liquid that pours into the cup into to make liquid can keep warm in the cup. And when the liquid in the cup is cooled to the temperature corresponding to the reference temperature mark, the phase-change material in the reference phase-change heat preservation part is changed from the first phase to the second phase, namely, the phase change is fully generated. Like this, the latent heat of phase transition of the phase change material who refers to phase transition heat preservation portion has obtained make full use of, can absorb more heat fast, and the liquid rapid cooling and the heat preservation in the cup of being convenient for. When the liquid in the cup is increased continuously, sensible heat can be utilized to exchange heat with the liquid in the cup by referring to the phase-change heat preservation part, so that the heat preservation temperature of the liquid in the cup is changed. Therefore, when the amount of liquid injected into the cup body is changed, the heat preservation temperature of the liquid in the cup body is also changed correspondingly, and the liquid with different heat preservation temperatures is obtained.

In other words, the heat preservation temperature of heat preservation utensil can be adjusted according to the liquid volume in the cup to the phase transition heat preservation layer, make same heat preservation utensil can have different heat preservation temperatures, then through adjusting the liquid volume of pouring into the cup, can obtain different heat preservation temperature's liquid, therefore be favorable to satisfying user's different user demands, the limitation that current phase transition heat preservation utensil only has single heat preservation temperature has effectively been overcome, interval selectivity of many temperatures is provided for the user, bring for the brand-new use of user and experience, can avoid the user to carry a plurality of cups, and reduce the user and wait for liquid refrigerated time, and it is more convenient to carry.

In addition, the phase-change heat-insulating layer is arranged in the interlayer and cannot contact with liquid in the cup body, so that the mode of insulating and cooling the liquid by utilizing the phase-change heat-insulating layer is safe and nontoxic. The phase-change material is widely available and low in price, and is beneficial to market popularization.

Wherein, reference liquid can be selected according to the application scene of heat preservation utensil, generally chooses the highest temperature liquid that contained liquid can reach under the ordinary pressure for use to when guaranteeing to pour into the liquid of other temperatures into the cup, also can rapid cooling and keep warm. Such as: when the heat preservation utensil is a vacuum cup and is mainly used for containing water, the reference liquid is boiling water with the temperature of 98-100 ℃; when the heat preservation utensil is a heat preservation soup box and is mainly used for containing soup liquid, the reference liquid is just boiled soup; when the heat preservation device is a heat preservation beverage cup and is mainly used for containing beverages (such as coffee, milk tea and the like), the reference liquid is a beverage which is just made.

It is worth to be noted that, through research, the existing phase-change heat preservation appliances are all filled with a single phase-change material excessively in the cup body, so that the phase-change material only undergoes phase change under the condition that the cup body is filled with liquid, and only latent heat is utilized to perform heat exchange with the liquid in the cup. Therefore, the heat preservation temperature is equal to the phase-change temperature of the phase-change material no matter how much liquid is injected into the cup, and the heat preservation can be carried out only at the phase-change temperature of the phase-change material. The scheme adopts a non-excessive filling mode, only under the condition that liquid in the cup is relatively less, the phase change material only changes phase, only utilizes latent heat to exchange heat with the liquid in the cup, and when the liquid in the cup is relatively more, the phase change material changes phase firstly, utilizes the latent heat of phase change to exchange heat with the liquid in the cup, and then utilizes sensible heat to exchange heat with the liquid in the cup, so that the liquid in the cup is kept at a temperature different from the phase change temperature of the liquid, and the multi-temperature control effect is realized.

In addition, the heat preservation device in the above embodiments provided by the present application may further have the following additional technical features:

in the above embodiment, the number of the temperature marks is at least two, a plurality of the temperature marks are arranged at intervals along the height direction of the cup body, and the reference temperature mark is the temperature mark with the lowest position.

A plurality of temperature signs have different position height, correspond different liquid level volume respectively, and the user of being convenient for rationally controls the liquid volume that pours into the cup according to the demand of oneself to improve user's use and experience. The temperature mark with the lowest position is selected as the reference temperature mark, when less liquid is injected into the cup, the temperature corresponding to the reference temperature mark can be kept, and when the liquid in the cup increases, the variation range of the heat preservation temperature is correspondingly increased, so that the temperature control interval of the heat preservation appliance is favorably increased.

In the above embodiment, the temperatures corresponding to a plurality of the temperature markers increase with the increase of the positions of the temperature markers; and marking the reference temperature marks as first temperature marks, wherein the plurality of temperature marks sequentially comprise the first temperature marks and second temperature marks according to the sequence of positions from low to high.

The higher the position of the temperature mark is, the higher the corresponding temperature is, so that the more the liquid amount in the cup is, the higher the heat preservation temperature of the heat preservation appliance is. When the liquid amount in the cup is more, the phase change heat preservation part absorbs the same heat, and the temperature of the liquid in the cup is reduced to be lower, so that the heat preservation temperature is higher. Therefore, the arrangement is reasonable, and the phase change latent heat and the phase change sensible heat of the phase change heat preservation part positioned at the lower position can be fully utilized to promote the heat exchange with the liquid in the cup.

In any of the above embodiments, the number of the phase change heat preservation parts is one.

In this scheme, phase change heat preservation portion can utilize comprehensively phase change latent heat and system sensible heat and liquid carries out the heat exchange in the cup to realize compound effect, make phase change heat preservation portion can how much carry out the interval regulation of many temperatures according to liquid, and then make the liquid of different liquid levels can have different heat preservation temperatures. Specifically, when less liquid is in the cup, the phase change heat preservation part carries out phase change, only latent heat is utilized to carry out heat exchange with the liquid in the cup, and the heat preservation temperature of the liquid is equal to the heat preservation temperature of the phase change heat preservation part; when the liquid in the cup is more, the phase-change heat preservation part can exchange heat with the liquid in the cup by utilizing sensible heat after phase change, so that the heat preservation temperature of the liquid is changed, and the heat preservation temperature of the liquid is not equal to the phase-change temperature of the phase-change heat preservation part. In addition, the amount of liquid in the cup is different, and the obtained heat preservation temperature is also different. Therefore, the multi-temperature interval selectivity of the heat preservation appliance is realized. Simultaneously, the phase transition heat preservation portion of this scheme only has one, and simple structure is favorable to reducing product cost, also is favorable to reducing product weight.

In the above embodiment, the phase transition temperature of the phase transition heat preservation part is equal to the temperature corresponding to the reference temperature mark; or the phase change temperature of the phase change heat preservation part is lower than the temperature corresponding to the reference temperature mark.

When the phase-change temperature of the phase-change heat preservation part is equal to the temperature corresponding to the reference temperature mark, the liquid level in the cup is ensured to be lower than or equal to the reference temperature mark, the phase-change heat preservation part only utilizes the phase-change latent heat to carry out heat exchange with the liquid in the cup, and the liquid in the cup can be preserved at the phase-change temperature of the phase-change heat preservation part, namely, the temperature corresponding to the reference temperature mark. Therefore, the user can optionally select the liquid amount lower than the reference temperature mark to be injected into the cup without worrying about the incapability of determining the temperature of the liquid in the cup, and the use comfort of the user is further improved.

Alternatively, the phase transition temperature of the phase transition heat retaining portion may be appropriately lower than the temperature corresponding to the reference temperature mark. Such as: the phase-change temperature of the phase-change heat preservation part is 38 ℃, the temperature corresponding to the reference temperature identification is 40 ℃, then the reference liquid of the liquid level corresponding to the reference temperature identification is cooled to 40 ℃, the phase-change material of the phase-change heat preservation part also completely changes phase, the heat of the liquid in the cup is rapidly absorbed, the sensible heat of the system is further utilized to exchange heat with the liquid in the cup, and finally the heat and the liquid in the cup reach 40 ℃ together. In this way, the selection range of the phase change material and the reference temperature marker is expanded.

In the above embodiment, the filling height of the phase change material of the phase change heat preservation part is located between the first temperature indicator and the second temperature indicator in the plurality of temperature indicators.

Can guarantee like this when the liquid level is less than first temperature sign in the cup, liquid can carry out the heat exchange with phase transition heat preservation portion fast in the cup, also guarantees simultaneously that phase transition heat preservation portion's phase change material's packing volume is enough to satisfy above-mentioned cooling heat retaining needs.

In the above embodiment, the temperature corresponding to the first temperature mark is 40 ℃; the second temperature indication corresponds to a temperature of 50 ℃.

The filling height of the phase-change material of the phase-change heat-preservation part is limited within the range from the temperature mark of 40 ℃ to the temperature mark of 50 ℃, so that the phase-change heat-preservation part can completely change phase when the liquid amount corresponds to the temperature mark of 40 ℃, the temperature of a system can quickly reach 40 ℃, and the phase-change heat-preservation part is suitable for being directly drunk by a user. And then when high-temperature liquid is continuously poured to reach the temperature mark of 50 ℃ and the temperature mark of 60 ℃, heat exchange is carried out in the system, so that the temperature equalization reaches 50 ℃ and 60 ℃ respectively, and the process is a structure of sensible heat exchange of the system and does not involve phase change latent heat storage. Therefore, the maximum filling height of the phase-change material is preferably set to be between 40 ℃ and 50 ℃, so that the phase-change heat storage process can be effectively and quickly carried out when high-temperature liquid is partially poured in.

In any of the above embodiments, the number of the phase-change heat-preserving parts is multiple, the multiple phase-change heat-preserving parts are distributed at intervals along the height direction of the cup body, and the phase-change temperatures of the multiple phase-change heat-preserving parts are increased along with the increase of the positions of the phase-change heat-preserving parts; the reference phase change heat preservation part is the phase change heat preservation part with the lowest position.

In this scheme, the phase transition heat preservation mainly utilizes a plurality of phase transition heat preservation portions to have different phase transition temperatures and realizes compound effect for the phase transition heat preservation has many phase transition temperature points, and then carries out the interval regulation of many temperatures, makes the liquid of different liquid levels can have different heat preservation temperatures. Specifically, a plurality of phase transition heat preservation portion have different phase transition temperature, and when the cup stood still on the mesa, the phase transition heat preservation portion below the liquid level all carried out the heat exchange with the liquid in the cup, then when the liquid level in the cup was lower, only corresponded one phase transition heat preservation portion of the below, mainly the phase transition heat preservation portion (refer to phase transition heat preservation portion promptly) of the below carried out the heat exchange with the interior liquid of cup, and then took place the phase transition, then the heat preservation temperature of liquid this moment corresponds the phase transition temperature of phase transition heat preservation portion of the below. When the liquid level in the cup is higher, when corresponding a plurality of phase transition heat preservation portion, a plurality of phase transition heat preservation portion all carry out the heat exchange with liquid in the cup, the liquid of different positions carries out heat exchange and the degree of heat exchange is different with the phase transition heat preservation portion that corresponds the position, also can carry out the heat exchange simultaneously between the liquid of different positions, this is equivalent to the liquid that a plurality of heat preservation temperature are different mixes, the heat preservation temperature of the liquid after the mixture that obtains can be between the highest temperature and minimum temperature, therefore the heat preservation temperature at this moment is different from the phase transition temperature that is located the phase transition heat preservation portion of below. In addition, the number of the phase-change heat preservation parts for exchanging heat with the liquid in the cup is different, and the heat preservation temperature of the obtained liquid is also different. Therefore, the multi-temperature interval selectivity of the heat preservation appliance is realized.

In other words, when the number of the phase change heat retaining parts is one, the phase change heat retaining part is referred to. When the quantity of phase transition heat preservation portion is a plurality of, a plurality of phase transition heat preservation portions arrange according to the direction of height of cup, and the phase transition heat preservation portion that leans on the bottom just refers to phase transition heat preservation portion. This scheme has carried out the sectional type to the latter phase transition heat preservation and has filled, and the height of each phase transition heat preservation portion can be the same, also can not be the same, also can partly be the same, specifically can be used for factors such as the specific heat capacity of splendid attire liquid according to the size of cup, cup reasonable design.

Wherein, the phase transition temperature of a plurality of phase transition heat preservation portions upwards risees gradually, then injects high temperature liquid into the cup, and when the liquid level in the cup was higher, the lower phase transition heat preservation portion of phase transition temperature and the higher phase transition heat preservation portion of phase transition temperature all can absorb the heat of liquid in the cup, and then takes place the phase transition for liquid rapid cooling in the cup, and then the user of being convenient for directly drinks, and the phase transition heat preservation portion under the liquid level can carry out long-time heat preservation to liquid in the cup. Therefore, the liquid can be insulated by fully utilizing the phase change latent heat of the phase change insulation part below the liquid surface no matter how much the liquid is in the cup body. Otherwise, if the higher phase transition heat preservation portion of phase transition temperature is arranged by lower, when the liquid level in the cup is higher, by arranging by lower and the higher phase transition heat preservation portion of phase transition temperature reaches balanced back at liquid temperature, because the holding temperature of liquid is less than the holding temperature of this phase transition heat preservation portion, this phase transition heat preservation portion can be to the interior liquid release heat of cup, and the temperature is reduced and the phase transition can not take place, does not make full use of this phase transition heat preservation portion's phase transition latent heat.

In addition, in the use process, the heat preservation utensil can be shaken to ensure that the liquid in the cup exchanges heat with the phase change heat preservation parts of all parts, thereby promoting the liquid in the cup to be quickly cooled and reach the balance temperature. After the temperature is reduced, when the heat preservation utensil is kept still on the table top, the liquid in the cup can only exchange heat with the phase change heat preservation part below the liquid level. When the liquid in the cup is more, the cup contains more heat, and the temperature is difficult to reduce; when the liquid in the cup is less, the heat contained in the cup is less, and the temperature is easier to reduce. Therefore, the phase change heat preservation part with lower phase change temperature is arranged at a relatively lower position, so that the low-temperature heat preservation of a small amount of liquid is facilitated; the phase-change heat-preservation part with higher phase-change temperature is arranged at the position which is relatively close to the upper part, so that the high-temperature heat preservation of a large amount of liquid is facilitated, the conception is ingenious, and the structure is reasonable.

In the above embodiment, the filling height of the phase change material of the reference phase change thermal insulation portion is lower than that of the second temperature indicator in the plurality of temperature indicators.

Therefore, when the liquid level in the cup is lower than the first temperature mark, the liquid in the cup mainly exchanges heat with the phase-change heat-preservation part located at the lowest position, and meanwhile, the filling amount of the phase-change material of the phase-change heat-preservation part located at the lowest position is enough to meet the requirements of temperature reduction and heat preservation.

In any of the above embodiments, the phase change heat preservation portion includes one of a binary or multi-element organic acid phase change material, a binary hydrated salt phase change material, and a binary or multi-element alloy phase change material.

The material is a common phase-change heat-insulating material, is widely available and has low price. The multi-temperature-regulation phase-change thermal insulation appliance can be obtained by reasonably selecting the phase-change thermal insulation material, reasonably proportioning and reasonably designing the filling amount.

Specifically, the phase-change heat-preservation part can comprise binary or polybasic organic acid, can be single phase-change material, such as stearic acid or paraffin, and can also be composite phase-change material, such as stearic acid-palmitic acid. The phase-change heat preservation part also comprises binary hydrated salt, which can be a single phase-change material, such as sodium acetate trihydrate, or a composite phase-change material, such as barium hydroxide octahydrate-magnesium chloride hexahydrate. The phase-change heat-preserving part can also comprise binary or multi-element alloy phase-change materials, such as Sn-Bi-In alloy and the like.

In any of the above embodiments, the phase transition temperature of the phase transition heat retaining portion is between 40 ℃ and 70 ℃.

The phase transition temperature of the phase transition heat-insulating layer is limited to be between 40 ℃ and 70 ℃, so that the heat-insulating temperature of the heat-insulating device is approximately between 40 ℃ and 70 ℃, and the heat-insulating device is suitable for being directly drunk by consumers. Of course, the phase transition temperature of the phase transition heat insulation layer is not limited to the range, and can be adjusted according to needs in the actual production process.

In any of the above embodiments, the cup body is provided with a visible window, the visible window is provided with a temperature label, and the temperature label is provided with a plurality of temperature marks; and/or a temperature sensing ink layer is arranged on the cup body and is used for displaying corresponding colors according to the temperature of liquid in the cup body; and/or the heat preservation device is provided with a temperature sensing electronic display which is used for displaying the temperature of the liquid in the cup body.

Set up visual window on the cup, the user can see the liquid level height in the cup through visual window. Establish the temperature label in visual window department, because the temperature label has a plurality of temperature signs that set up along the direction of height interval of cup, therefore the user observes the specific position that the liquid level height in the cup corresponds the temperature label through visual window, can learn the liquid temperature in the cup, is favorable to further improving user's use and experiences. Further, the viewing window may be made of transparent glass or plastic. Wherein the temperature indication includes but is not limited to: scale lines, temperature values, text, etc.

And the temperature-sensitive ink changes color, so that the cup body can display different colors, and a good decorative effect is achieved, thereby being beneficial to improving the attractiveness of the product and further improving the use experience of a user. Meanwhile, when the temperature of the temperature sensing ink layer does not change, the temperature of the liquid in the cup is balanced. Therefore, the temperature sensing ink layer can visually show whether the current temperature is balanced or not, and the user can be prevented from being scalded due to overhigh local temperature of the liquid. Such as: when the temperature-sensing ink layer shows blue, the liquid in the cup is indicated to be at low temperature; when the temperature sensing ink layer shows orange color, the liquid in the cup is at the medium temperature; when the temperature-sensing ink layer shows red, the liquid in the cup is indicated to be at high temperature. In addition, the temperature-sensing ink layer can avoid a visible window from being arranged on the cup body, so that the structure of the cup body is simplified, the processing technology of the cup body is simplified, and the product appearance is optimized. Wherein, the temperature sensing printing ink layer can be established at the local of cup, also can cover whole cup by a large scale. The temperature-sensing ink layer can be arranged on the outer wall surface of the interlayer, and the temperature of the phase-change heat-insulation layer in the interlayer is equal to the temperature of liquid in the cup, so that the temperature-sensing ink layer can indirectly sense the temperature of the liquid in the cup by sensing the temperature of the phase-change heat-insulation layer.

The temperature sensing electronic display can visually display the real-time temperature in the cup body, so that a user can know the accurate temperature of the liquid in the cup in time conveniently, and the detection precision is high. Meanwhile, when the temperature value displayed by the temperature sensing electronic display does not change, the temperature of the liquid in the cup is indicated to be balanced. Therefore, the temperature sensing electronic display can also visually show whether the current temperature is balanced or not, and is favorable for preventing the user from being scalded due to overhigh local temperature of the liquid. In addition, the adoption of the temperature-sensing electronic display can avoid the arrangement of a visible window on the cup body, thereby being beneficial to simplifying the structure of the cup body, simplifying the processing technology of the cup body and optimizing the appearance of a product.

Wherein, the three schemes are not influenced mutually, one of the schemes can be selected optionally, and the schemes can be combined freely. When the first time is selected, the product structure can be simplified, and the production cost can be reduced; when the combination is free, the users can be prompted from different angles, the use habits of different users can be favorably met, and the use comfort of the users is further improved. Such as: the temperature label is used with the temperature sensing ink layer or the temperature sensing electronic display in a combined mode, and a user can inject water into the cup body according to the needs of the user and the temperature label. After water is injected, the cup cover is covered, the cup body is fully shaken, and the heat exchange efficiency is improved.

Detailed Description

In order that the above objects, features and advantages of the present application can be more clearly understood, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.

The following describes an insulation device provided by some embodiments of the present application with reference to fig. 1 to 5.

The present application provides a thermal insulation device, as shown in fig. 1 and 4, including: cup 1, bowl cover 2 and phase transition heat preservation 3.

Specifically, the cup body 1 is provided with the interlayer 11, as shown in fig. 2, and the cup body 1 is provided with at least one temperature mark 131, wherein one temperature mark 131 is a reference temperature mark 1310.

The phase change insulating layer 3 is arranged in the interlayer 11 and used for exchanging heat with liquid in the cup body 1 as shown in figure 2.

The phase-change insulating layer 3 includes at least one phase-change insulating portion 31, wherein the phase-change insulating portion 31 refers to the phase-change insulating portion 311. And the filling amount of the phase-change material in the reference phase-change thermal insulation portion 311 and the reference temperature indicator 1310 satisfy the following relationship:

when the reference liquid at the liquid level corresponding to the reference temperature indicator 1310 is cooled to the temperature corresponding to the reference temperature indicator 1310, the phase-change material in the reference phase-change thermal insulation portion 311 changes from the first phase to the second phase. Such as: the first phase is a solid phase, and the second phase is a liquid phase; or the first phase is a solid phase and the second phase is a gas phase; or the first phase is a liquid phase and the second phase is a gas phase.

The application provides a heat preservation utensil through set up phase change heat preservation 3 in the intermediate layer 11 at cup 1, utilizes the liquid in phase change heat preservation 3 and the cup 1 to carry out the heat exchange, changes the temperature of the liquid that pours into in the cup 1 to make liquid can keep warm in cup 1.

When the reference liquid (e.g. hot water of 98-100 ℃) at the liquid level corresponding to the reference temperature mark 1310 is injected into the cup, and the temperature of the liquid in the cup is reduced to the temperature corresponding to the reference temperature mark 1310, the phase change material of the reference phase change heat preservation part 311 changes from the first phase to the second phase, that is, the phase change is fully performed. Thus, the latent heat of the phase change material referring to the phase change heat preservation part 311 is fully utilized, more heat can be absorbed quickly, and the liquid in the cup can be cooled and preserved conveniently and quickly. When the amount of liquid in the cup increases, the reference phase-change thermal insulation portion 311 may exchange heat with the liquid in the cup by sensible heat, thereby changing the thermal insulation temperature of the liquid in the cup. Therefore, when the amount of liquid injected into the cup body is changed, the heat preservation temperature of the liquid in the cup body is also changed correspondingly, and the liquid with different heat preservation temperatures is obtained.

In other words, phase change heat preservation 3 can be according to the heat preservation temperature of heat preservation utensil is adjusted to the liquid volume in the cup 1, make same heat preservation utensil can have different heat preservation temperatures, then through adjusting the liquid volume of pouring into in to the cup 1, can obtain the liquid of different heat preservation temperatures, therefore be favorable to satisfying user's different user demands, effectively overcome current phase change heat preservation utensil and only have the limitation of single heat preservation temperature, interval selectivity of multi-temperature is provided for the user, bring for the brand-new use of user and experience, can avoid the user to carry a plurality of cups, and reduce the user and wait for liquid refrigerated time, and it is more convenient to carry.

In addition, the phase-change heat-insulating layer 3 is arranged in the interlayer 11 and cannot contact with the liquid in the cup body 1, so that the mode of heat insulation and temperature reduction of the liquid by utilizing the phase-change heat-insulating layer 3 is safe and nontoxic. The phase-change material is widely available and low in price, and is beneficial to market popularization.

The reference liquid can be selected according to the application scene of the heat preservation appliance, and the highest temperature liquid which can be reached by the contained liquid under normal pressure is generally selected, so that the liquid can be quickly cooled and preserved when the liquid with other temperatures is injected into the cup. Such as: when the heat preservation utensil is a vacuum cup and is mainly used for containing water, the reference liquid is boiling water with the temperature of 98-100 ℃; when the heat preservation utensil is a heat preservation soup box and is mainly used for containing soup liquid, the reference liquid is just boiled soup; when the heat preservation device is a heat preservation beverage cup and is mainly used for containing beverages (such as coffee, milk tea and the like), the reference liquid is a beverage which is just made.

It is worth to be noted that, through research, the existing phase-change heat preservation devices are all that single phase-change materials are excessively filled in the cup body 1, so that under the condition that the cup body 1 is filled with liquid, the phase-change materials only change phase, and only latent heat is utilized to exchange heat with the liquid in the cup. Therefore, the heat preservation temperature is equal to the phase-change temperature of the phase-change material no matter how much liquid is injected into the cup, and the heat preservation can be carried out only at the phase-change temperature of the phase-change material. The scheme adopts a non-excessive filling mode, only under the condition that liquid in the cup is less, the phase change material only changes phase, only latent heat is utilized to exchange heat with the liquid in the cup, when the liquid in the cup is more, the phase change material changes phase firstly, and then sensible heat is utilized to exchange heat with the liquid in the cup, so that the liquid in the cup is kept at a temperature different from the phase change temperature of the liquid, and the multi-temperature control effect is realized.

Specifically, the number of the temperature markers 131 is one, and the temperature markers 131 are formed as reference temperature markers 1310; alternatively, the temperature indicator 131 is provided in plural numbers, the plural temperature indicators 131 are provided at intervals in the height direction of the cup body 1, and the temperature indicator 131 at the lowest position is formed as the reference temperature indicator 1310.

The number of the phase change heat retaining portions 31 is one, and the phase change heat retaining portions 31 are formed to refer to the phase change heat retaining portions 311; alternatively, the number of the phase change heat retaining portions 31 is plural, the plural phase change heat retaining portions 31 are provided at intervals in the height direction of the cup body 1, and the phase change heat retaining portion 31 at the lowest position is formed as the reference phase change heat retaining portion 311. Briefly described.

In short, the reference temperature indicator 1310 is the lowest-position temperature indicator 131, and the reference phase change heat retaining unit 311 is the lowest-position phase change heat retaining unit 31. The temperature mark 131 with the lowest position is selected as the reference temperature mark 1310, when less liquid is injected into the cup, the temperature corresponding to the reference temperature mark 1310 can be kept at the temperature, and when the amount of the liquid in the cup increases, the variation range of the heat-preservation temperature is correspondingly increased, so that the temperature control interval of the heat-preservation appliance is favorably increased. Because the liquid level of the liquid in the cup can automatically increase from bottom to top under the action of gravity, the liquid is firstly subjected to heat exchange with the phase change heat preservation part 31 with the lowest position. Therefore, the phase-change heat-preserving part 31 with the lowest position is selected as the reference phase-change heat-preserving part 311, and when the filling amount of the phase-change material of the reference phase-change heat-preserving part 311 is designed, the influence of other phase-change heat-preserving parts 31 is not easy to affect, and the product design is facilitated to be simplified.

In some embodiments, the cup body 1 is provided with at least one temperature indicator 131, the phase-change insulation layer 3 comprises at least one phase-change insulation part 31, and the filling amount of the phase-change material of the phase-change insulation part 31 located at the lowest position and the temperature indicator 131 located at the lowest position satisfy the following relationship:

when the temperature of the reference liquid at the liquid level corresponding to the temperature indicator 131 at the lowest position is decreased to the temperature corresponding to the temperature indicator 131 at the lowest position, the phase change material of the phase change heat preservation portion 31 at the lowest position completely changes phase.

Specifically, when the reference liquid (e.g., hot water of 98 to 100 ℃) is injected into the cup body 1 and the temperature indicator 131 at the lowest position of the liquid level of the reference liquid is located, the liquid in the cup mainly exchanges heat with the phase change heat retaining portion 31 located at the lowest position. When the liquid is cooled to the temperature corresponding to the lowest temperature mark 131, the phase change thermal insulation portion 31 located at the lowest position completely changes phase, so that the phase change thermal insulation portion 31 located at the lowest position exchanges heat with the liquid by using at least latent heat of phase change, and the heat stored by the latent heat of phase change is much greater than the sensible heat of the system, so that the liquid in the cup body 1 can quickly reach the temperature corresponding to the lowest temperature mark 131 at the position. When the liquid amount in the cup body 1 is continuously increased, the phase-change heat preservation part 31 at the lowest position can exchange heat with the liquid in the cup body 1 by utilizing system sensible heat, and when the number of the phase-change heat preservation parts 31 is increased, the phase-change heat preservation part 31 at the higher position can also obviously exchange heat with the liquid in the cup, so that the heat preservation temperature of the liquid in the cup body 1 is changed. Therefore, when the amount of liquid filled into the cup body 1 is changed, the heat preservation temperature of the liquid in the cup is also changed correspondingly, so that the liquid with different heat preservation temperatures is obtained.

In some embodiments of the present application, the number of temperature markers 131 is at least two, as shown in fig. 1. The plurality of temperature marks 131 are provided at intervals in the height direction of the cup body 1. The reference temperature indicator 1310 is the lowest temperature indicator 131.

A plurality of temperature sign 131 have different position height, correspond different liquid level volume respectively, and the user of being convenient for injects the liquid volume in the cup 1 according to the reasonable control of own demand to improve user's use and experience.

Further, the temperatures corresponding to the plurality of temperature markers 131 increase as the positions of the temperature markers 131 increase, as shown in fig. 1. The reference temperature indicator 1310 is denoted as a first temperature indicator 1311, and the plurality of temperature indicators 131 sequentially include the first temperature indicator 1311 and a second temperature indicator 1312 in descending order of position.

The higher the position of the temperature mark 131, the higher the corresponding temperature, and thus the more the amount of liquid in the cup, the higher the temperature of the warming instrument. As the amount of liquid in the cup increases, the phase change insulation 31 absorbs the same amount of heat, and the temperature of the liquid in the cup decreases, resulting in a higher insulation temperature. Therefore, the layout is reasonable, and the phase change latent heat and the phase change sensible heat of the phase change heat preservation part 31 at the lower position can be fully utilized to promote the heat exchange with the liquid in the cup.

In some embodiments, the number of phase change attemperation portions 31 is one, as shown in fig. 2.

In this scheme, phase change heat preservation portion 31 can utilize comprehensively phase change latent heat and system sensible heat and liquid carries out the heat exchange in the cup to realize compound effect, make phase change heat preservation portion 31 can how much carry out the interval regulation of many temperatures according to liquid, and then make the liquid of different liquid levels can have different heat preservation temperatures.

Specifically, when the liquid in the cup is less, the phase-change heat preservation part 31 changes phase, and only latent heat is utilized to exchange heat with the liquid in the cup, and the heat preservation temperature of the liquid is equal to the heat preservation temperature of the phase-change heat preservation part 31. When the liquid in the cup is more, after the phase change occurs in the phase change heat preservation part 31, sensible heat can be used for exchanging heat with the liquid in the cup, so that the heat preservation temperature of the liquid is changed, and the heat preservation temperature of the liquid is not equal to the phase change temperature of the phase change heat preservation part 31. In addition, the amount of liquid in the cup is different, and the obtained heat preservation temperature is also different. Therefore, the multi-temperature interval selectivity of the heat preservation appliance is realized.

Meanwhile, only one phase change heat preservation part 31 is arranged, the structure is simple, the product cost is favorably reduced, and the product weight is also favorably reduced.

In one embodiment, the phase transition temperature of the phase transition heat retaining portion 31 is equal to the temperature corresponding to the reference temperature indicator 1310. Or, the phase transition temperature of the phase transition heat retaining part 31 is equal to the temperature corresponding to the temperature indicator 131 located at the lowest position.

When the number of the temperature marks 131 is one, the temperature mark 131 is the reference temperature mark 1310, that is, the temperature mark 131 located at the lowest position. When the number of the temperature marks 131 is plural, the plural temperature marks 131 are arranged in the height direction of the cup body 1, and the lowermost temperature mark 131 is the temperature mark 131 at the lowermost position, that is, the reference temperature mark 1310.

When this scheme has guaranteed that the liquid level is less than or equal to the temperature sign 131 of lowest position in the cup, phase transition heat preservation portion 31 only utilizes the latent heat of phase transition and carries out the heat exchange with the interior liquid of cup, and the interior liquid of cup can both keep warm in the phase transition temperature department of this phase transition heat preservation portion 31, keeps warm promptly at the temperature that the temperature sign 131 of lowest position corresponds. Thus, the user can optionally select the liquid amount of the temperature mark 131 lower than the lowest position to be injected into the cup without worrying about the incapability of determining the temperature of the liquid in the cup, thereby further improving the use comfort of the user.

In another embodiment, the phase transition temperature of the phase transition heat retaining portion 31 is lower than the temperature corresponding to the reference temperature indicator 1310 (i.e., the temperature indicator 131 located at the lowest position).

The phase transition temperature of the phase transition heat retaining portion 31 may be appropriately lower than the temperature corresponding to the temperature indicator 131 at the lowest position. Such as: the phase transition temperature of the phase transition heat preservation portion 31 is 38 ℃, the temperature corresponding to the temperature mark 131 at the lowest position is 40 ℃, then the reference liquid at the liquid level corresponding to the temperature mark 131 at the lowest position is cooled to 40 ℃, the phase transition material of the phase transition heat preservation portion 31 also completely undergoes phase transition, the heat of the liquid in the cup is rapidly absorbed, the sensible heat of the system is utilized to exchange heat with the liquid in the cup, and finally the temperature and the liquid in the cup reach 40 ℃ together. In this way, it is advantageous to expand the selection range of the phase change material and the temperature marker 131 located at the lowermost position.

In the above embodiment, the filling level of the phase change material of the phase change insulation part 31 is located between the first temperature marker 1311 and the second temperature marker 1312 of the plurality of temperature markers 131.

Therefore, when the liquid level in the cup is lower than the first temperature mark 1311, the liquid in the cup can exchange heat with the phase-change heat preservation part 31 quickly, and meanwhile, the filling amount of the phase-change material of the phase-change heat preservation part 31 at the lowest position is enough to meet the requirements of temperature reduction and heat preservation.

In a particular embodiment, specifically, as shown in FIG. 1, the first temperature indicator 1311 corresponds to a temperature of 40 ℃. The second temperature indicator 1312 corresponds to a temperature of 50 ℃.

The filling height of the phase change material of the phase change heat preservation part 31 is limited in the range from the temperature mark 131 of 40 ℃ to the temperature mark 131 of 50 ℃, so that the phase change heat preservation part 31 can completely change the phase when the liquid amount corresponds to the temperature mark 131 of 40 ℃, the temperature of the system can quickly reach 40 ℃, and the phase change heat preservation part is suitable for being directly drunk by a user. And then when high-temperature liquid is continuously poured to the temperature marks 131 and 131 at 50 ℃ and 60 ℃, heat exchange is carried out in the system, so that the temperature equalization reaches 50 ℃ and 60 ℃ respectively, and the process is a structure of sensible heat exchange of the system and does not involve phase-change latent heat storage. Therefore, the maximum filling height of the phase-change material is preferably set to be between 40 ℃ and 50 ℃, so that the phase-change heat storage process can be effectively and quickly carried out when high-temperature liquid is partially poured in.

Wherein, the phase-change thermal insulation part 31 comprises at least two phase-change materials.

Alternatively, the phase change heat retaining portion 31 includes a phase change material.

Phase change heat preservation portion 31 can be single phase change material, and then the phase transition temperature of this phase change heat preservation portion 31 is fixed temperature, is convenient for design phase change material's packing volume according to factors such as the size of cup 1, the specific heat capacity that is used for splendid attire liquid to satisfy the demand of product, be favorable to simplifying the product design.

Phase transition heat preservation portion 31 also can include multiple phase transition material, and then the phase transition temperature of this phase transition heat preservation portion 31 has a plurality of phase transition points, is equivalent to a temperature interval, is favorable to increasing the quantity in the temperature interval of heat preservation utensil, provides more temperature choices for the user, further improves user's use and experiences.

In other embodiments of the present application, the number of the phase change heat retaining portions 31 is plural, as shown in fig. 5. The phase-change heat-preservation parts 31 are distributed at intervals along the height direction of the cup body 1, adjacent phase-change heat-preservation parts 31 are separated by the partition layer 32, and the phase-change temperature of the phase-change heat-preservation parts 31 rises along with the rise of the position of the phase-change heat-preservation part 31. The reference phase change heat retaining portion 311 is the phase change heat retaining portion 31 located at the lowest position.

Alternatively, when the number of the phase change heat retaining portions 31 is one, the phase change heat retaining portion 31 located at the lowest position is the reference phase change heat retaining portion 311. When the number of the phase-change heat-preserving portions 31 is plural, the plural phase-change heat-preserving portions 31 are arranged in the height direction of the cup body 1, and the phase-change heat-preserving portion 31 which is the lowermost position is the phase-change heat-preserving portion 31, that is, the reference phase-change heat-preserving portion 311.

In this scheme, phase change heat preservation 3 mainly utilizes a plurality of phase transition heat preservation portions 31 to have different phase transition temperatures and realizes compound effect for phase transition heat preservation 3 has many phase transition temperature points, and then carries out the interval regulation of many temperatures, makes the liquid of different liquid levels can have different heat preservation temperatures.

Specifically, the phase-change heat preservation portions 31 have different phase-change temperatures, and when the cup body 1 is placed on the table top, the phase-change heat preservation portions 31 below the liquid level exchange heat with the liquid in the cup body 1, and when the liquid level in the cup body 1 is low and only corresponds to one of the phase-change heat preservation portions 31 at the lowest position, mainly the phase-change heat preservation portion 31 at the lowest position (i.e., the phase-change heat preservation portion 311) exchanges heat with the liquid in the cup, so that phase change occurs, and the heat preservation temperature of the liquid at this time corresponds to the phase-change temperature of the phase-change heat preservation portion 31 at the.

When the liquid level in the cup body 1 is higher and corresponds to the phase-change heat preservation parts 31, the phase-change heat preservation parts 31 exchange heat with liquid in the cup, the liquid at different parts and the phase-change heat preservation parts 31 at corresponding positions exchange heat and the heat exchange degree is different, meanwhile, the liquid at different parts also exchange heat, which is equivalent to mixing of the liquids with different heat preservation temperatures, the obtained mixed liquid has the heat preservation temperature between the highest temperature and the lowest temperature, and therefore the heat preservation temperature at the moment is different from the phase-change temperature of the phase-change heat preservation part 31 at the lowest position. Further, the number of phase change heat retaining portions 31 that exchange heat with the liquid in the cup is different, and the heat retaining temperature of the obtained liquid is also different. Therefore, the multi-temperature interval selectivity of the heat preservation appliance is realized.

In other words, this scheme has carried out the sectional type to phase change heat preservation 3 and has filled, and each phase change heat preservation 31 highly can be the same, also can not be the same, also can be partly the same, specifically can be used for the specific heat capacity etc. factor rational design of splendid attire liquid according to cup 1's size, cup 1.

In one embodiment of the present application, the phase transition temperature of the phase transition heat preservation portions 31 increases in sequence along a direction close to the cup lid 2.

The phase transition temperature of a plurality of phase transition heat preservation portions 31 upwards risees gradually, then injects high temperature liquid into cup 1, and when the liquid level in the cup 1 was higher, the heat of liquid in the cup can all be absorbed to the lower phase transition heat preservation portion 31 of phase transition temperature and the higher phase transition heat preservation portion 31 of phase transition temperature, and then takes place the phase transition for liquid rapid cooling in the cup, and then the user of being convenient for directly drinks, and the liquid can carry out long-time heat preservation to liquid in the cup in the phase transition heat preservation portion 31 under the liquid level. Thus, the latent heat of phase change of the phase change heat retaining portion 31 below the liquid surface can be fully utilized to retain the heat of the liquid regardless of the amount of the liquid in the cup body 1.

Otherwise, if the phase change heat preservation part 31 with higher phase change temperature is arranged below, when the liquid level in the cup body 1 is higher, the phase change heat preservation part 31 which is arranged below and has higher phase change temperature reaches equilibrium at the liquid temperature, because the heat preservation temperature of the liquid is lower than the heat preservation temperature of the phase change heat preservation part 31, the phase change heat preservation part 31 can release heat to the liquid in the cup, the temperature is reduced without phase change, and the latent heat of phase change of the phase change heat preservation part 31 is not fully utilized.

In addition, in the using process, the heat preservation device can be shaken to enable the liquid in the cup to exchange heat with the phase change heat preservation parts 31 of all parts, so that the liquid in the cup is enabled to be rapidly cooled and reach the balance temperature. After the temperature is reduced, when the heat preservation device is placed on the table top, the liquid in the cup can only exchange heat with the phase change heat preservation part 31 below the liquid level. When the liquid in the cup is more, the cup contains more heat, and the temperature is difficult to reduce; when the liquid in the cup is less, the heat contained in the cup is less, and the temperature is easier to reduce. Therefore, the phase change heat preservation part 31 with lower phase change temperature is arranged at a relatively lower position, so that the low-temperature heat preservation of a small amount of liquid is facilitated; the phase change heat preservation part 31 with higher phase change temperature is arranged at the position which is relatively close to the upper part, so that the high-temperature heat preservation of a large amount of liquid is facilitated, the conception is ingenious, and the structure is reasonable.

Such as: the number of the phase-change heat preservation parts 31 is three, the phase-change temperature of the first phase-change heat preservation part 31 is 40 ℃, the phase-change temperature of the second phase-change heat preservation part 31 is 60 ℃, and the phase-change temperature of the third phase-change heat preservation part 31 is 70 ℃. When the liquid level is not higher than the first phase change heat preservation part 31, the heat preservation temperature of the liquid is 40 ℃; when the liquid level is between the second phase-change heat-preservation part 31 and the first phase-change heat-preservation part 31, the heat preservation temperature of the liquid is between 40 ℃ and 60 ℃; when the liquid level is between the second phase change heat preservation part 31 and the third phase change heat preservation part 31, the heat preservation temperature of the liquid is between 60 ℃ and 70 ℃.

In the above embodiment, the filling height of the phase change material with reference to the phase change holding part 311 (i.e., the phase change holding part 31 located at the lowest position) is lower than the second temperature indicator 131 among the plurality of temperature indicators 131.

Therefore, when the liquid level in the cup is lower than the first temperature mark 131, the liquid in the cup mainly exchanges heat with the phase-change heat-preserving part 31 located at the lowest position, and meanwhile, the filling amount of the phase-change material of the phase-change heat-preserving part 31 located at the lowest position is enough to meet the requirements of temperature reduction and heat preservation.

Wherein, at least one phase change heat preservation part 31 comprises at least two phase change materials.

Alternatively, at least one phase change insulation portion 31 includes a phase change material.

Alternatively, at least one phase change insulation part 31 includes at least two phase change materials, and at least one phase change insulation part 31 includes one phase change material.

Phase change heat preservation portion 31 can be single phase change material, and then the phase transition temperature of this phase change heat preservation portion 31 is fixed temperature, is convenient for design each phase change heat preservation portion 31's height according to factors such as the size of cup 1, the specific heat capacity that is used for splendid attire liquid to satisfy the demand of product, be favorable to simplifying the product design.

Because the quantity of phase change heat preservation portion 31 is a plurality of, each phase change heat preservation portion 31 separates each other, therefore the kind of the phase change material that each phase change heat preservation portion 31 includes is unrestricted, can rationally select as required.

In any of the above embodiments, further, the phase change heat preservation portion 31 includes one of a binary or multi-element organic acid phase change material, a binary hydrated salt phase change material, and a binary or multi-element alloy phase change material.

Specifically, the phase-change heat-preserving part 31 may include a binary or polybasic organic acid, and may be a single phase-change material, such as stearic acid or paraffin, or a composite phase-change material, such as stearic acid-palmitic acid. The phase-change heat preservation part 31 can also comprise binary hydrated salt, which can be a single phase-change material, such as sodium acetate trihydrate, or a composite phase-change material, such as barium hydroxide octahydrate-magnesium chloride hexahydrate. The phase change heat retaining portion 31 may also include a binary or multi-element alloy phase change material, such as an Sn-Bi-In alloy.

Of course, the phase change material used in the phase change heat preservation part 31 is not limited to the above scheme, and can be adjusted as required in the actual production process.

In any of the above embodiments, specifically, the phase transition temperature of the phase transition heat retaining portion 31 is between 40 ℃ and 70 ℃.

The phase transition temperature of the phase transition heat-insulating layer 3 is limited to 40 ℃ to 70 ℃, such as 40 ℃, 50 ℃, 60 ℃, 70 ℃, 80 ℃ and the like, so that the heat-insulating temperature of the heat-insulating device is approximately between 40 ℃ to 70 ℃, and the heat-insulating device is suitable for direct drinking of consumers.

In the following, a specific example is described by taking a vacuum cup as an example, and compared with the prior art.

The vacuum cup is a common article in life, generally is a water container made of glass or stainless steel and a vacuum layer, the top of the vacuum cup is tightly sealed by a cover, and the vacuum heat insulation layer can delay heat dissipation of liquid such as water and the like in the vacuum cup so as to achieve the purpose of heat preservation. Due to the heat insulation effect of vacuum heat preservation, hot water (about 95 ℃) is difficult to cool to the temperature which can be directly drunk, which brings inconvenience to the use.

Except for a vacuum heat preservation mode, the novel phase change heat preservation effect is obvious, and the phase change heat preservation utilizes solidification of a solid-liquid phase change material to achieve the heat preservation effect. It has a longer incubation time compared to vacuum incubation. However, the phase-change temperature of the cup based on the phase-change material can only be fixed at the temperature for heat preservation, and more drinkable temperatures cannot be provided, so that the application scene of the vacuum cup is limited.

In order to overcome the above disadvantages, the present example provides a novel multi-temperature regulating phase change thermal cup. Its typical advantages are as follows: (1) the thermos cup can lead the temperature of water in the cup to reach a corresponding temperature interval on a corresponding scale mark through adjusting the proportion and the filling amount of the phase-change material and researching a heat transfer system according to the needs of a user and pouring the amount of hot water, and can preserve heat in the temperature interval, thereby providing a brand-new and very good drinking experience for the user; (2) the selected heat preservation and cooling modes are safe and nontoxic; (3) the selected phase-change thermal insulation material is widely and easily available and has low price.

In order to achieve the purpose, the novel multi-temperature regulation phase change thermal cup comprises a thermal cup cover and a cup body, wherein the cup body is of a composite multilayer structure, and composite phase change materials are directly or sectionally filled in an interlayer of an inner wall, so that hot drinks can be subjected to heat exchange and temperature reduction within 30-60 s; a layer of heat preservation resin is arranged outside the cup body; the surface of the cup body is provided with a visual window, a temperature label (or temperature sensing ink or a temperature sensing electronic display) is stuck at the window, and when hot water is poured into a specified scale, the temperature of the hot water at 95 ℃ can be reduced to a temperature range of 40-70 ℃ and is kept for more than 4 hours.

The thermos cup of this example, rational in infrastructure, can be fine select the temperature of drink to satisfy the user and to the demand of the different temperature tastes of drink, can avoid the user to carry a plurality of cups, reduce and wait for the refrigerated time of drink, it is more convenient to carry, improves user experience and feels.

Specifically, a novel phase change thermos cup with multiple temperature regulation, as shown in fig. 1, includes: a heat preservation cup cover 2 and a cup body 1.

Wherein, the inner layer 21 of the heat-preservation cup cover 2 is made of polyethylene, polypropylene, polycarbonate or polymethyl methacrylate and other materials, and the outer layer 22 of the heat-preservation cup cover 2 is made of food-grade stainless steel; the inner layer 21 of the heat-preserving cup cover 2 can isolate the hot drink in the heat-preserving cup from the air and the outer layer 22 of the cup cover 2.

The cup body 1 is provided with an interlayer and is made of food-grade 304 stainless steel; the outer layer of the cup body 1 is compounded with a layer of resin material to realize heat preservation and heat insulation and enhance the hand feeling of holding. The interlayer 11 is filled with composite phase-change materials with phase-change temperature of 40-70 ℃, such as: binary or polybasic organic acid composite phase-change materials, binary hydrated salt composite phase-change materials, binary or polybasic low-temperature alloys and the like.

The cup body 1 is provided with a transparent visual window 12, and the edge of the window is attached with water temperature scales (namely a temperature label 13). When hot water is poured into the corresponding scale openings, the cup body is fully shaken for 1min, and then the water temperature is reduced to a corresponding temperature range, so that the aim of multi-temperature regulation, temperature reduction and temperature control is fulfilled. The window material is made of transparent glass or plastic.

Furthermore, the periphery of the window is attached with temperature sensing ink or a temperature sensing electronic display, so that whether the current temperature is balanced or not can be visually presented.

When the cup is used, high-temperature hot water (95 ℃) is poured into the vacuum cup according to corresponding scales, the cup cover 2 is tightly covered, the cup body is uniformly shaken for 1min, and then the water temperature is reduced to a corresponding temperature range, so that the aim of multi-temperature regulation, temperature reduction and temperature control is fulfilled. When the temperature sensing ink or the temperature sensing electronic display displays the corresponding temperature, the user can drink the temperature sensing ink or the temperature sensing electronic display by opening the cover, so that the overhigh local temperature caused by insufficient heat exchange is avoided.

Before multiple use, the cup body 1 needs to be cooled by cold water so as to prevent the internal heat from being released insufficiently and influencing the temperature regulation function.

So, the novel phase transition thermos cup that this example provided has following advantage:

(1) this thermos cup has overcome the limitation of the single phase transition temperature of traditional phase transition heat preservation portion, provides the interval selectivity of many temperatures, gives the user a brand-new very good experience of drinking water.

(2) The selected heat preservation and cooling modes are safe and nontoxic.

(3) The selected cooling material is widely available and has low price.

In short, the principle of this example is:

the vacuum cup with multiple temperature selectivity (40-70 ℃) is prepared by adopting the principle that the solid-liquid phase change material is subjected to phase change at the temperature higher than the phase change temperature to store the heat of the high-temperature hot water and the principle that the phase change material can continuously exchange heat with the high-temperature hot water after being completely subjected to phase change to increase the water temperature, and the hot water is subjected to cooling and heat preservation treatment.

By designing composite phase-change materials with different proportions or not excessively filling the phase-change materials, accurate multi-temperature interval temperature control is realized.

The temperature sensing ink has a temperature sensing color change effect at a specific temperature, and the temperature sensing electronic device can accurately display the real-time temperature.

The phase change material may be selected from the following materials: binary or polybasic organic acid, binary or polybasic hydrated salt and binary or polybasic low-temperature alloy composite phase-change material.
