Description

Technical Field

[0001] The utility model relates to the technical field of thermos cups, in particular to a heat storage solar water cup suitable for high-cold areas. Background Art

[0002] With the development of science and technology, the types and functions of water cups have become more and more abundant and powerful. Among them, the invention of the thermos cup allows us to drink comfortable hot water even in the cold outdoors. However, for outdoor areas with extreme environments, such as the high altitude and cold Qinghai-Tibet Plateau, existing thermos cups have some shortcomings. Traditional thermos cups use internal and external layers and a vacuum in the middle to block heat dissipation. They can only keep water warm. When drinking water is urgently needed, it cannot quickly cool the hot water to a temperature suitable for people.

[0003] In recent years, thermostatic water cups have appeared, such as the phase change thermostatic cup in patent application number CN201510292654, which adds phase change heat storage material between the inner and outer layers. When hot water is added, the solid material in the interlayer absorbs heat and melts into liquid, cooling the water in the inner layer to a temperature suitable for human drinking.

[0004] However, in the high and cold outdoors, if you stay for too long, the water in the thermos will also become cold, and in an emergency, you need to get snow to make water. Therefore, it is further hoped that the thermos can have a heating function, but there is currently a lack of such products. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the water in the thermos cup will also become cold if it stays in the cold outdoors for too long, thereby providing a heat storage solar water cup suitable for cold areas.

[0006] In order to solve the above technical problems, the utility model provides a heat storage solar water cup suitable for high-cold areas, comprising: a cup body, the cup body comprising an outer wall, a middle wall, and an inner wall, the outer wall being a transparent part, the middle wall being provided with a solar thermal part, a phase change heat storage cavity being formed between the middle wall and the inner wall, the phase change heat storage cavity being provided with a phase change heat storage material, the inner wall being provided with a water storage chamber, the water storage chamber being used for storing water; a cup cover, arranged at the top of the cup body; a base, arranged at the bottom of the cup body, the base being provided with an electric heating part, and the electric heating part being arranged at the bottom of the middle wall.

[0007] Furthermore, a vacuum insulation cavity is formed between the outer wall and the middle wall, and the solar thermal component is located in the vacuum insulation cavity.

[0008] Furthermore, the solar thermal component is a heat-absorbing coating or a flexible photovoltaic panel.

[0009] Furthermore, the heat-absorbing coating is a black nickel coating, a black chromium coating, a carbon black coating, or a graphene coating.

[0010] Furthermore, the middle wall and the inner wall are made of stainless steel or aluminum alloy, titanium or ceramic.

[0011] Furthermore, the outer wall is made of acrylic plate or glass.

[0012] Furthermore, a receiving cavity is provided on the base, and the electric heating element is arranged in the receiving cavity.

[0013] Furthermore, the electric heating element includes an electric heating plate and an interface, the electric heating plate is arranged at the bottom of the middle wall, and the interface is connected to the electric heating plate.

[0014] Furthermore, it also includes a cup mouth, which is arranged on the top of the cup body and connected to the cup cover.

[0015] Furthermore, the cup cover, the cup mouth, and the base are made of organic polymer material.

[0016] The technical solution of the utility model has the following advantages:

[0017] The utility model provides a heat storage solar water cup suitable for use in high-cold areas, comprising: a cup body, the cup body comprising an outer wall, a middle wall, and an inner wall, the outer wall being a transparent part, the middle wall being provided with a solar thermal part, a phase change heat storage cavity being formed between the middle wall and the inner wall, the phase change heat storage cavity being provided with a phase change heat storage material, the inner wall being provided with a water storage chamber, the water storage chamber being used for storing water; a cup cover being provided at the top of the cup body; a base being provided at the bottom of the cup body, the base being provided with an electric heating part, and the electric heating part being provided at the bottom of the middle wall.

[0018] When cooling or keeping warm, open the cup lid, pour boiling water into the water storage chamber, cover the cup lid and shake it. At this time, the heat is conducted to the phase change heat storage cavity through the inner wall, and the phase change heat storage material filled in the phase change heat storage cavity absorbs heat and undergoes phase change, thereby storing the heat of the boiling water. On the one hand, the boiling water is quickly cooled to a temperature of about 40 to 55°C, which is suitable for drinking; on the other hand, the heat will continue to be conducted to the middle wall. At this time, the outermost wall can block long-wave radiation, thereby minimizing heat dissipation.

[0019] By setting the cup body as a transparent part, the water cup can absorb sunlight from all directions without dead angles, that is, the sunlight passes through the outer wall and enters the solar thermal part of the middle wall; when the water needs to be heated, the sunlight is absorbed by the solar thermal part and converted into heat, and the heat is conducted through the middle wall, the phase change heat storage material, the inner wall, and heats the cold water in the water storage chamber. When the water temperature reaches the melting point of the phase change material, the phase change heat storage material no longer continues to heat the water, so the water temperature will not be too high. When there is no external power supply, the cup can rely on solar energy for heating, which is suitable for outdoor activities such as border patrols and outdoor adventures in high-altitude areas. When there is an external power supply, the middle wall can be heated by the electric heating element, and then the heat is transferred to the phase change heat storage material and the inner wall, thereby heating the cold water in the water storage chamber.

[0020] This heat storage solar water cup suitable for alpine areas has both cooling and heat preservation functions. The phase change heat storage material is set so that the water temperature can be quickly adjusted to a suitable drinking temperature after adding boiling water. In addition, food-grade dyes are added to the phase change heat storage material. If the water cup is damaged, the color will change significantly to prevent users from eating it by mistake. In addition, the cup is provided with solar thermal components and electric heating components, which can be charged to heat water; when there is no power supply, the water cup can be placed in the sun to heat the water, and due to the presence of the phase change heat storage cavity and the phase change heat storage material, heat can be stored and heat loss can be reduced, which is suitable for outdoor use in alpine areas. At the same time, this heat storage solar water cup suitable for alpine areas has a simple structure and is easy to produce, process and use in practice.

[0033] See also Figure 1 to Figure 2 As shown, the utility model provides a heat storage solar water cup suitable for high-cold areas, comprising: a cup body 1, the cup body 1 comprising an outer wall 2, a middle wall 3, and an inner wall 4, the outer wall 2 being a transparent part, the middle wall 3 being provided with a solar thermal part 5, a phase change heat storage cavity 6 being formed between the middle wall 3 and the inner wall 4, the phase change heat storage cavity 6 being provided with a phase change heat storage material, the inner wall 4 being provided with a water storage chamber 7, the water storage chamber 7 being used for storing water; a cup cover 8, arranged at the top of the cup body 1; a base 9, arranged at the bottom of the cup body 1, the base 9 being provided with an electric heating part, the electric heating part being arranged at the bottom of the middle wall 3.

[0034] When cooling or keeping warm, open the cup cover 8, pour boiled water into the water storage chamber 7, cover the cup cover 8 and shake it. At this time, the heat is transferred to the phase change heat storage cavity 6 through the inner wall 4, and the phase change heat storage material filled in the phase change heat storage cavity 6 absorbs the heat and undergoes phase change, thereby storing the heat of the boiled water. On the one hand, the boiled water is quickly cooled to a temperature of about 40 to 55°C, which is suitable for drinking; on the other hand, the heat will continue to be transferred to the middle wall 3. At this time, the outermost wall 2 can block long-wave radiation, thereby minimizing heat dissipation.

[0035] By setting the cup body 1 as a transparent part, the water cup can absorb sunlight from all directions without dead angles, that is, the sunlight passes through the outer wall 2 and enters the solar thermal component 5 of the middle wall 3; when it is necessary to heat the water, the sunlight is absorbed by the solar thermal component 5 and converted into heat, and the heat is conducted through the middle wall 3, the phase change heat storage material, the inner wall 4, and heats the cold water in the water storage chamber 7. When the water temperature reaches the melting point of the phase change material, the phase change heat storage material no longer continues to heat the water, so the water temperature will not be too high. When there is no external power supply, the cup can rely on solar energy for heating, and is suitable for outdoor activities such as border patrols in high-cold areas and outdoor adventures. When there is an external power supply, the middle wall 3 can be heated by an electric heater, and then the heat is transferred to the phase change heat storage material and the inner wall 4, thereby heating the cold water in the water storage chamber 7.

[0036] The heat storage solar water cup suitable for alpine areas has the dual functions of cooling and heat preservation. The phase change heat storage material is set so that the water temperature can be quickly adjusted to a suitable drinking temperature after adding boiled water. In addition, food-grade dyes are added to the phase change heat storage material. If the water cup is damaged, obvious color changes can occur to prevent users from eating it by mistake. In addition, the cup is provided with a solar thermal element 5 and an electric heating element, which can be charged to heat water; when there is no power supply, the water cup can be placed in the sun to heat the water, and due to the presence of the phase change heat storage cavity 6 and the phase change heat storage material, heat can be stored and heat loss can be reduced, which is suitable for outdoor use in alpine areas. At the same time, the heat storage solar water cup suitable for alpine areas has a simple structure and is easy to produce, process and use in practice.

[0037] The phase change heat storage material includes a phase change material and a high thermal conductivity additive. The phase change material includes but is not limited to: solid-liquid phase change materials of crystalline hydrated salts, paraffins, fatty acids and their derivatives, solid-solid phase change materials of polyols and polyethylene, etc.; the high thermal conductivity additive includes but is not limited to: metal nanoparticles, carbon nanotubes, graphene, porous thermal conductive media, thermal conductive microcapsules, etc.

[0038] The metal salt crystalline hydrate includes calcium chloride hexahydrate, sodium thiosulfate pentahydrate and sodium sulfate decahydrate.

[0039] A vacuum insulation cavity 10 is formed between the outer wall 2 and the middle wall 3, and the solar thermal element 5 is located in the vacuum insulation cavity 10. The vacuum insulation cavity 10 can block heat conduction, so that the water can maintain a suitable drinking temperature for a long time. At the same time, the setting of the vacuum insulation cavity 10 can protect the solar thermal element 5, prevent the solar thermal element 5 from being damaged, and ensure the service life of the solar thermal element 5.

[0040] Specifically, the solar thermal element 5 is a heat absorbing coating or a flexible photovoltaic panel, wherein the heat absorbing coating is a black nickel coating, a black chromium coating, a carbon black coating or a graphene coating.

[0041] Flexible photovoltaic panels are made of amorphous silicon or copper indium gallium selenide thin films, cadmium telluride, perovskite, nickel chromium oxynitride film, titanium nitride, and aluminum nitride.

[0042] In this embodiment, the middle wall 3 and the inner wall 4 are made of stainless steel or aluminum alloy, titanium, or ceramic, thereby increasing the thermal conductivity and thermal efficiency of the inner wall 4 and the middle wall 3 .

[0043] Specifically, the stainless steel material is food grade stainless steel material.

[0044] The outer wall 2 is made of acrylic plate or glass. Meanwhile, the outer surface of the outer wall 2 can also be anti-slip.

[0045] The thermal conductivity of acrylic sheet is less than 0.15W / (mK).

[0046] In some optional embodiments, a receiving cavity 11 is provided on the base 9 , and the electric heating element is provided in the receiving cavity 11 .

[0047] Specifically, the electric heating element includes an electric heating plate 12 and an interface 13, wherein the electric heating plate 12 is disposed at the bottom of the middle wall 3, and the interface 13 is connected to the electric heating plate 12. When there is an external power supply, the middle wall 3 can be heated by the electric heating element, and then the heat is transferred to the phase change heat storage material and the inner wall 4, thereby heating the cold water in the water storage chamber 7.

[0048] In some optional embodiments, the heat storage solar water cup suitable for use in high-cold areas further includes a cup mouth 14 , which is disposed on the top of the cup body 1 , and is connected to the cup cover 8 .

[0049] Specifically, the cup mouth 14 is connected to the outer wall 2, the middle wall 3, and the inner wall 4, and the inner wall 4 of the cup mouth 14 is in the same plane as the inner wall 4 of the cup body 1. At the same time, an external thread can be provided on the outer wall 2 of the cup mouth 14, so that the cup mouth 14 can be connected to the cup cover 8. Of course, the cup mouth 14 can also be connected to the cup cover 8 by snapping.

[0050] In this embodiment, the cup cover 8, the cup mouth 14, and the base 9 are made of organic polymer material, which can significantly reduce the heat conduction through them and achieve long-term heat preservation. Specifically, the organic polymer can be a plastic product or a fiber product.

[0051] The operating principle of this heat storage solar water cup suitable for high-cold areas is as follows:

[0052] When cooling or keeping warm, open the cup cover 8, pour boiled water into the water storage chamber 7, cover the cup cover 8 and shake it. At this time, the heat is conducted to the phase change heat storage cavity 6 through the inner wall 4. The phase change heat storage material filled in the phase change heat storage cavity 6 absorbs heat and undergoes phase change, thereby storing the heat of the boiled water. On the one hand, the boiled water is quickly cooled to a temperature of about 40 to 55°C, which is suitable for drinking. On the other hand, the heat will continue to be conducted to the middle wall 3, and the existence of the vacuum insulation cavity 10 blocks the heat conduction. The heat can only be dissipated by thermal radiation. At this time, the outermost wall 2 can hinder long-wave radiation, thereby minimizing the heat dissipation as much as possible.

[0053] When hot water is needed, add cold water or ice and snow into the water storage chamber 7, cover the cup cover 8, insert the power supply into the interface 13, and the electric heating plate 12 generates heat after power is turned on; if there is no power supply, put the cup upside down in the sunlight. Since the entire outer wall 2 is a transparent acrylic plate, the water cup can absorb sunlight from all directions without dead angles. The short-wave radiation of the sun passes through the acrylic plate, is absorbed by the solar thermal element 5 and converted into heat. The heat is conducted through the middle wall 3, the phase change heat storage material, and the inner wall 4 to heat the cold water in the water storage chamber 7. When the water temperature reaches the melting point of the phase change material, the phase change heat storage material no longer continues to heat the water, so the water temperature will not be too high. When there is no external power supply, the cup can rely on solar energy to achieve heating, which is suitable for outdoor activities such as border patrols and outdoor adventures in high-altitude areas.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
