Description

Technical Field

[0001] The invention relates to the field of thermos cups, and in particular to a color-changing temperature-controlled cup. Background Art

[0002] The main function of a thermos cup is to keep the beverage in the cup warm. The thermos cups currently sold on the market are generally made of a silver-plated glass liner and a ceramic or stainless steel vacuum layer. The vacuum insulation layer is used to delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation. It has the following shortcomings: First, it only has the function of heat preservation, with a simple structure and a single function. It cannot display the temperature of the water in the thermos cup, and cannot serve as a reminder for people who have special requirements for water temperature; second, the water in the thermos cup cannot be quickly cooled to a suitable drinking temperature and cannot be drunk in a short time; third, the vacuum technology is generally used for heat preservation, which is not only expensive but also complicated in production process. In order to solve the above problems, more and more scientific researchers have proposed to apply phase change materials to thermos cups.

[0003] Phase change materials refer to substances that change their physical properties with temperature and can provide latent heat. Phase change materials have the ability to change their physical state within a certain temperature range. Taking solid-liquid phase change as an example, when heated to the melting temperature, a phase change from solid to liquid occurs. During the melting process, the phase change material absorbs and stores a large amount of latent heat; when the phase change material cools, the stored heat must be dissipated to the environment within a certain temperature range, and the reverse phase change from liquid to solid is performed. In these two phase change processes, the energy stored or released is called the latent heat of phase change. When the physical state changes, the temperature of the material itself remains almost unchanged before the phase change is completed, forming a wide temperature platform. Although the temperature remains unchanged, the latent heat absorbed or released is quite large.

[0004] The existing thermos cups all use phase change materials to achieve rapid cooling and extend the insulation time. Their shortcomings are that they cannot be manually adjusted and the temperature time period cannot be controlled. They can only cool at one point according to the properties of the phase change material and can only keep warm within a temperature range. Therefore, their applications are relatively single. They are suitable for keeping water warm, but not for brewing beverages such as green tea that have strict requirements on brewing temperature, brewing time and drinking temperature. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention proposes a color-changing temperature-controlled cup, and the specific technical solution is as follows:

[0006] A color-changing temperature-controlled cup comprises an outer shell, a cup cover arranged on the outer shell, an inner liner arranged in the outer shell, a plurality of groups of reversible temperature-sensitive color-changing sheets embedded in the outer shell, a plurality of groups of mounting grooves arranged between the outer shell and the inner liner, and a temperature-control board arranged in the mounting groove, wherein the temperature-control board comprises a mounting plate arranged in the mounting groove, a phase-change material layer arranged on one side of the mounting plate, and a first heat-insulating layer arranged on the other side of the mounting plate, and a second heat-insulating layer is arranged on the inner wall of the outer shell.

[0007] Preferably, the temperature sensing range and temperature sensing color of the reversible thermochromic film are different.

[0009] Preferably, a avoidance groove corresponding to the reversible thermochromic sheet is provided on the temperature control plate, and the reversible thermochromic sheet passes through the avoidance groove and is connected to the inner tank.

[0010] The present invention enables the reversible temperature-sensitive color-changing sheet to pass through the avoidance groove and directly contact the inner container, thereby improving the sensing accuracy of the reversible temperature-sensitive color-changing sheet and making the temperature display of the present invention more accurate and reliable.

[0011] Preferably, a bottom cover threadedly connected to the housing is provided at the bottom side of the housing and at the opening end of the mounting groove.

[0012] The present invention seals the temperature control plate and the inner tank in the installation groove by means of a bottom cover arranged on the bottom side of the shell, thereby improving the heat preservation performance of the present invention.

[0013] Preferably, a rotating handle is provided on the bottom side of the bottom cover.

[0014] In the present invention, the user can tighten the bottom cover or remove it from the bottom end of the shell by rotating the handle to the left or right.

[0015] Preferably, the temperature control plates are evenly distributed on the outside of the inner liner in a circumferential direction with the inner liner as the center.

[0016] The present invention evenly distributes the temperature control plates on the outer side of the inner liner in a circumferential direction with the inner liner as the center, so that the inner liner is wrapped in the temperature control plates to achieve the best temperature control effect.

[0017] Preferably, a handle is provided on the bottom side of the mounting plate.

[0018] The present invention facilitates the user to pull the temperature control plate out of the installation groove through the pull handle, thereby improving the practicality and convenience of the present invention.

[0020] The present invention enables the user to observe and understand the temperature of the liquid in the inner container more intuitively and specifically through the temperature mark.

[0021] Preferably, the inner side of the inner container is provided with scales.

[0022] The present invention provides scales on the inner side of the inner liner, so that medical staff and users can grasp the amount of liquid in the inner liner at any time by opening the cup cover, which is convenient for clinical recording.

[0023] Preferably, an electronic clock is provided on the outer side of the housing.

[0024] The present invention provides an electronic clock on the outer side of the shell, so that users can make timed reminders according to their own needs. When the time reaches the timed time of the electronic clock, the electronic clock can make a sound to remind the user.

[0025] The present invention has the following beneficial effects:

[0026] In the present invention, multiple groups of reversible thermochromic sheets embedded in the outer shell will reversibly change color to indicate the temperature as the temperature of the liquid in the inner tank changes. When the liquid reaches different temperatures, the reversible thermochromic sheets corresponding to the temperature sensing range and the instant temperature will show color, and the temperature sensing colors of the reversible thermochromic sheets are different, which helps the user understand the temperature change of the liquid. At the same time, the first thermal insulation layer and the second thermal insulation layer are provided. After the user knows the water temperature through the reversible thermochromic sheets, if it is high temperature, the first thermal insulation layer and the second thermal insulation layer can prevent burns, which is convenient to carry.

[0027] At the same time, the present invention arranges the phase change material layer and the first heat insulation layer relative to each other, and the user can flip the temperature control plate as needed, so that the inner liner can be in contact with the phase change material layer and can be sealed by the first heat insulation layer, thereby achieving the functions of controlling the temperature at a specific temperature point and keeping warm in a specific time period. In addition, the present invention reduces the temperature difference between the temperature inside the shell and the ambient temperature, slows down the temperature drop in the cup, and absorbs and stores part of the heat energy, which has the effect of replenishing heat energy and slows down the process of temperature drop in the cup.

[0038] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] See also Figures 1 to 4The present invention comprises a shell 1, a cup cover 2 arranged at the top of the shell 1, and an inner liner 3 arranged in the shell 1. The cross-sectional shape of the inner liner 3 is a regular hexagon and the cup cover 2 is threadedly connected to the shell 1 and is used to seal the inner liner 3, so as to achieve the effect of keeping the liquid in the inner liner 3 warm. An electronic clock 13 is arranged on the outside of the shell 1. The present invention enables users to make time reminders according to their own needs through the electronic clock 13 arranged on the outside of the shell 1. When the time reaches the timer time of the electronic clock, the electronic clock 13 can make a sound to remind the user. The model of the electronic clock 13 is an electronic watch commonly used in the prior art. It carries a power supply for energy supply and time reminder function, which improves the practicality and convenience of the present invention. Eight groups of reversible temperature-sensitive color-changing sheets 4 are embedded in the shell 1. The temperature sensing ranges and temperature sensing colors of the eight groups of reversible temperature-sensitive color-changing sheets 4 are different. A temperature mark 8 corresponding to the sensing temperature of the reversible temperature-sensitive color-changing sheets 4 is arranged on the outside of the shell 1, so that users can observe and understand the liquid temperature in the inner liner 3 more intuitively and specifically. In the present invention, multiple groups of reversible thermochromic sheets 4 embedded in the outer shell 1 will reversibly change color to indicate the temperature as the temperature of the liquid in the inner tank 3 changes. When the liquid reaches different temperatures, the reversible thermochromic sheets 4 corresponding to the temperature sensing range and the instantaneous temperature will show color, and the temperature sensing colors of the reversible thermochromic sheets 4 are different, which helps the user understand the temperature changes of the liquid.

[0040] See also Figure 1 and Figure 4 , eight groups of reversible thermochromic sheets 4 are injection molded by polypropylene transparent plastic mixed with thermochromic pigments, and the temperature-sensitive colors of the eight groups of reversible thermochromic sheets 4 are arranged in order of the cold and warm color tones, from the installation height from high to low, light blue, blue, green, purple, yellow, orange, red and dark red; the thermochromic temperatures are below 30°C, 30°C, 40°C, 50°C, 60°C, 70°C, 80°C and above 80°C, and are distributed on the housing 1 from bottom to top according to the color change temperature from low to high; when the temperature continues to rise, as the temperature rises, the color changes step by step according to the color change temperature of the thermochromic pigment. The thermochromic pigment in the present invention is prepared from an electron transfer type organic compound system, which is a type of organic color system with a special chemical structure. At a specific temperature, the molecular structure of the organic matter changes due to electron transfer, thereby achieving color change.

[0041] See also Figure 1 to Figure 2, eight groups of mounting grooves 5 are provided between the shell 1 and the liner 3, and a temperature control plate 6 for controlling the temperature of the liquid in the liner 3 is provided in the mounting groove 5. The eight groups of temperature control plates 6 are evenly distributed on the outer side of the liner 3 with the liner 3 as the center, so that the liner 3 is wrapped in the eight groups of temperature control plates 6 to achieve the best temperature control effect. In the present invention, the temperature control plate 6 in contact with the reversible thermochromic sheet 4 is provided with an avoidance groove 7 corresponding to the reversible thermochromic sheet 4, so that the reversible thermochromic sheet 4 can pass through the avoidance groove 7 and directly contact the liner 3, thereby improving the sensing accuracy of the reversible thermochromic sheet 4, and making the temperature display of the present invention more accurate and reliable. In addition, the four peripheral sides of the reversible thermochromic sheet 4 are coated with a heat-insulating material to prevent the temperature interference of the temperature control plate 6. A scale 31 is provided on the inner side of the liner 3. The present invention enables medical staff and users to grasp the amount of liquid in the liner 3 by opening the cup cover 2 at any time by setting the scale 31 on the inner side of the liner 3, which is convenient for medical staff to make clinical records.

[0042] See also Figure 2 to Figure 3 The temperature control board 6 includes a mounting plate 61 disposed in the mounting groove 5, a phase change material layer 62 disposed on one side of the mounting plate 61, and a first thermal insulation layer 63 disposed on the other side of the mounting plate 61. The inner wall of the outer shell 1 is provided with a second thermal insulation layer 12 for cooperating with the first thermal insulation layer 63 to isolate the heat of the phase change material layer 62. The present invention arranges the phase change material layer 62 and the first thermal insulation layer 63 relative to each other. The user can take out and flip the temperature control board 6 from the mounting groove 5 as needed, so that the inner tank 3 can be in contact with the phase change material layer 62 and can be sealed by the first thermal insulation layer 63, thereby achieving the functions of controlling the temperature at a specific temperature point and keeping the temperature in a specific time period. The first thermal insulation layer 63 and the second thermal insulation layer 12 are provided at the same time. After the user knows the water temperature through the reversible temperature-sensitive color-changing sheet 4, if it is high temperature, the first thermal insulation layer 63 and the second thermal insulation layer 12 can prevent burns, which is convenient to carry;

[0043] The material used for the phase change material layer 62 is an alloy phase change material or a non-metallic phase change material. The alloy phase change material is a gallium-based alloy, a bismuth-based alloy or a tin-based alloy with a melting point between 45°C and 65°C. The non-metallic phase change material is a paraffin material, a fatty acid / lipid, a hydrated salt, etc. with a melting temperature between 50°C and 65°C. And the preparation method of the phase change material layer 62 is: firstly prepare the alloy phase change material according to the formula ratio, and then melt the alloy phase change material in a vacuum induction melting furnace. Put the ingredients into a melting crucible, evacuate the vacuum induction melting furnace, wait until the pressure in the furnace is lower than 5×10-3Pa, then add an inert gas (nitrogen or argon) as a protective gas into the vacuum induction melting furnace, pressurize it to 0.5-0.8 atmospheres, and start power-on melting. After the melting is completed, cool it to room temperature, and then take out the alloy phase change material obtained by melting from the furnace. Use a water bath heating method to melt the alloy phase change material and pour it into a mold to finally form a finished product.

[0044] See also Figure 1 , a bottom cover 11 threadedly connected to the bottom side of the housing 1 and located at the open end of the mounting groove 5 is provided. The present invention seals the temperature control plate 6 and the inner tank 3 in the mounting groove 5 by the bottom cover 11 provided on the bottom side of the housing 1, thereby improving the heat preservation performance of the present invention during use and reducing heat loss. At the same time, a rotating handle 111 is provided on the bottom side of the bottom cover 11 for the user to rotate the bottom cover 11. The user can tighten the bottom cover 11 or remove it from the bottom end of the housing 1 by rotating the bottom cover 11 to the left or right. At the same time, a pull handle 611 is also provided on the bottom side of the mounting plate 61 for the user to pull the temperature control plate 6 out of the mounting groove 5, further improving the practicality and convenience of the present invention.

[0045] When the inner tank 3 is filled with hot drinks at a certain temperature, take 100°C boiling water for tea brewing as an example, first loosen the bottom cover 11 and take out the temperature control plate 6, so that the phase change material layer 62 on the temperature control plate 6 is in direct contact with the inner tank 3, and then tighten the bottom cover 11. At this time, the boiling water conducts heat to the phase change material layer 62. The phase change material layer 62 absorbs this heat energy, causing the liquid temperature in the inner tank 3 to drop rapidly. When the reversible temperature-sensitive color-changing sheet 4 with a sensing temperature of 80°C lights up red, it shows that the liquid temperature in the inner tank 3 has dropped to a suitable tea brewing temperature of 80°C, take out the temperature control plate 6, make the first heat insulation layer 63 on the temperature control plate 6 directly contact with the inner tank 3, and then tighten the bottom cover 11, add tea leaves to brew tea, and the brewing time is 5-10 minutes. At this time, since the first heat insulation layer 63 seals and surrounds the inner tank 3, the liquid temperature in the inner tank 3 can be maintained at 80°C. Finally, the temperature control plate 6 is taken out for the third time so that the phase change material layer 62 on the temperature control plate 6 is in direct contact with the inner pot 3. At this time, the phase change material layer 62 on the temperature control plate 6 continues to absorb heat until the temperature of the tea in the inner pot 3 continues to drop to the temperature range of 50°C-60°C, so that the temperature of the tea is not too high or too hot, and it is convenient to drink; and the phase change material layer 62 also continues to absorb, store, and release the heat energy released by the tea, and keeps the temperature of the tea in this temperature range suitable for human drinking for a long time.

[0046] In the present invention, the multiple groups of reversible thermochromic sheets 4 embedded in the outer shell 1 will reversibly change color to indicate the temperature as the temperature of the liquid in the inner liner 3 changes. When the liquid reaches different temperatures, the reversible thermochromic sheets 4 corresponding to the temperature sensing range and the instant temperature will show color, and the temperature sensing colors of the reversible thermochromic sheets 4 are different, which helps the user understand the temperature change of the liquid; at the same time, the present invention arranges the phase change material layer 62 and the first thermal insulation layer 63 relative to each other, and the user can flip the temperature control plate 6 as needed, so that the inner liner 3 can be in contact with the phase change material layer 62 and can be sealed by the first thermal insulation layer 63, thereby realizing the function of controlling the temperature at a specific temperature point and keeping warm in a specific time period, and the present invention reduces the temperature difference between the temperature in the outer shell 1 and the ambient temperature, slows down the temperature drop in the cup, and absorbs and stores part of the heat energy, which has the effect of replenishing heat energy and slows down the process of temperature drop in the cup.
