Description

Technical Field

[0001] The utility model belongs to the field of daily necessities production, in particular to a thermos cup with a phase change material adding structure. Background Art

[0002] In daily life, drinking boiled water is an essential part of maintaining human health, playing a vital role in improving quality of life and promoting healthy eating. Boiled water, due to its purity and absence of impurities, is widely considered an ideal source of drinking water. However, once water is heated to a boiling point, its high temperature is often unsuitable for direct drinking. Users typically need to wait for the water to cool naturally to a suitable drinking temperature. This process is not only time-consuming but also extremely inconvenient for users who urgently need to replenish their water, reducing the immediate drinking experience.

[0003] To improve this situation, a variety of products designed to quickly control hot water temperature have emerged on the market, meeting users' demand for convenient and efficient drinking water solutions. Among these, temperature control using phase change materials (PCMs) has become a research hotspot due to its high efficiency and environmental friendliness. PCMs can absorb and release large amounts of heat within a specific temperature range while maintaining a relatively stable temperature. This unique thermal property gives them broad potential for application in temperature control.

[0004] In existing water cup designs that use phase change materials for temperature control, the phase change material is often placed directly inside the cup, exchanging heat through direct contact with the water inside. While this arrangement can achieve a certain temperature control effect, the phase change material container may become damaged over time due to aging. Furthermore, the use and removal of the phase change material container during insertion into the cup increases the chance of damage. Once damaged, the phase change material may leak into the cup, contaminating the water and potentially posing a health threat to the user. If the phase change material is added to the cup body interlayer, a phase change material addition structure is required to ensure the addition of the phase change material and the thermal insulation and temperature control functions of the thermos cup. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a thermos cup with a phase change material adding structure. The phase change material adding structure adds the phase change material to the interlayer of the cup body to ensure the temperature control effect, while solving the problem in the prior art that the phase change material container is placed inside the water cup, which is inconvenient to take out and easy to damage, causing phase change material leakage.

[0006] To achieve the above-mentioned and other related purposes, the present invention provides a thermos cup with a phase change material added structure, comprising a cup body, wherein the cup body is a double-layer structure including a heat-uniform layer and a heat-insulating layer;

[0007] A temperature control element is arranged in the heat-uniform layer, and an adding structure for adding phase change material into the temperature control element is fixedly installed between the temperature control element and the inner wall of the cup body;

[0008] The heat insulation layer is sleeved on the outside of the heat uniforming layer.

[0009] Optionally, the temperature control component includes a phase change material container, and the top wall of the phase change material container is recessed inward to form a container groove for accommodating the fixed addition structure.

[0010] Optionally, the additional structure includes a phase change material injection tube and a uniform heating layer injection tube; the phase change material injection tube and the uniform heating layer injection tube are coaxially arranged, and the uniform heating layer injection tube is fixedly sleeved on the outside of the phase change material injection tube.

[0011] Optionally, the bottom end of the phase change material injection pipe is fixedly connected to the bottom wall of the accommodating tank, and the phase change material injection pipe is connected to the interior of the temperature control component; the top end of the phase change material injection pipe is arranged in the uniform heating layer injection pipe.

[0012] Optionally, the top of the uniform heating layer injection tube is fixedly connected to the bottom end of the inner wall of the cup body, and the uniform heating layer injection tube is connected to the interior of the inner wall of the cup body; the bottom end of the uniform heating layer injection tube is fixedly connected to the bottom of the phase change material injection tube.

[0013] Optionally, a heat conducting sheet is horizontally arranged inside the phase change material container, and there are multiple heat conducting sheets evenly distributed along the height direction of the temperature control component to form a multi-layer heat conducting structure.

[0014] Optionally, a heat conducting plate through hole is provided on the heat conducting plate to facilitate the flow and filling of the phase change material.

[0015] Optionally, a hydrophilic layer is arranged in the heat-uniform layer, and the hydrophilic layer is made of a capillary water-conducting material.

[0016] Optionally, a heat-insulating cover is further included, which is fixed on the top of the cup body.

[0017] As described above, the thermos cup with a phase change material added structure of the present invention has at least the following beneficial effects:

[0018] The utility model designs the cup body into a double-layer structure with an insulating layer arranged outside the uniform heat layer, and realizes rapid heat transfer by adding a temperature control component in the uniform heat layer. The fixed installation addition structure between the temperature control component and the inner wall of the cup body facilitates the addition of phase change material into the temperature control component. The phase change material cooperates with the uniform heat layer to transfer the heat of the water inside the cup body to the temperature control component, thereby completing the regulation of the drinking water temperature. In addition, the temperature control component is arranged in the uniform heat layer rather than in direct contact with the drinking water. This layout avoids the potential risk of contamination of the drinking water in the cup by the temperature control component, ensures the safety and hygiene of the drinking water, and solves the problem in the prior art that the phase change material container is placed inside the water cup, which is inconvenient to access and easy to be damaged, causing leakage of the phase change material.

[0019] The utility model designs the phase change material adding structure into a double-layer sleeve structure, including a phase change material injection pipe and a heat uniform layer injection pipe. The phase change material injection pipe is located inside the double-layer sleeve structure and is directly connected to the interior of the temperature control component, which facilitates the addition of phase change material (negative pressure addition or a built-in elbow to extend one end of the elbow into the top of the temperature control component to extract air), ensuring that the phase change material can be accurately and quickly injected into the interior of the temperature control component. The heat uniform layer injection pipe is sleeved on the outside of the phase change material injection pipe to form a compact double-layer sleeve structure. After the addition of the phase change material is completed, the phase change material injection pipe is closed, and a heat uniform medium (such as pure water) is added to the heat uniform layer injection pipe. After the addition is completed, it is closed and finally, the phase change characteristics of pure water (the volume expands when ice is frozen, and water starts to freeze from the end close to the bottom of the inner wall) are utilized by cooling the bottom end of the inner wall of the cup body to open the seals of the phase change material injection pipe and the heat uniform layer injection pipe. The heat uniform medium is exposed to the vacuum heat uniform layer to vaporize or liquefy and activate the working ability of the heat uniform layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figures 1 to 5The present invention provides a thermos cup with a phase change material adding structure, comprising a cup body 1, wherein the cup body 1 is a double-layer structure comprising a heat-uniform layer 2 and a heat-insulating layer 3; a temperature-controlling component 4 is arranged in the heat-uniform layer 2, and an adding structure for adding phase change material to the inside of the temperature-controlling component is fixedly installed between the temperature-controlling component 4 and the inner wall of the cup body 1; the heat-insulating layer 3 is sleeved on the outside of the heat-uniform layer 2. This application realizes rapid heat transfer by designing the cup body 1 into a double-layer structure in which the heat-uniform layer 2 is sleeved with the heat-insulating layer 3, and by adding the temperature-controlling component 4 in the heat-uniform layer 2. The fixedly installed adding structure between the temperature-controlling component 4 and the inner wall of the cup body 1 facilitates vacuuming and high-temperature brazing to seal the vacuum heat-insulating layer 3 and the heat-uniform layer 2. , the phase change material is added to the inside of the temperature control component 4 (which solves the problem that after the phase change material is filled, the uniform heat layer 2 and the heat insulation layer 3 are vacuumed and high-temperature brazed to seal the vacuum heat insulation layer 3 and the uniform heat layer 2, which may cause the phase change material to vaporize and cause an explosion). The phase change material cooperates with the uniform heat layer to transfer the heat of the water inside the cup body 1 to the temperature control component 4, thereby completing the regulation of the drinking water temperature. In addition, the temperature control component 4 is arranged in the uniform heat layer 2 instead of directly contacting the drinking water. This layout avoids the potential contamination risk of the temperature control component 4 to the drinking water in the cup, ensures the safety and hygiene of the drinking water, and solves the problem in the prior art that the phase change material container is placed inside the water cup, which is inconvenient to take and easy to damage, causing the phase change material to leak.

[0031] In this embodiment, please refer to Figure 1 and Figure 4The temperature control component 4 includes a phase change material container, the top wall of the phase change material container is recessed inward to form a container groove for accommodating a fixed addition structure, the addition structure includes a phase change material injection pipe 5 and a heat uniform layer injection pipe 6; the phase change material injection pipe 5 and the heat uniform layer injection pipe 6 are coaxially arranged, and the heat uniform layer injection pipe 6 is fixedly sleeved on the outside of the phase change material injection pipe 5, the bottom end of the phase change material injection pipe 5 is fixedly connected to the bottom wall of the container groove, and the phase change material injection pipe 5 is fixedly connected to the temperature control component 4 The top end of the phase change material injection tube 5 is arranged in the uniform heat layer injection tube 6, and the top end of the uniform heat layer injection tube 6 is fixedly connected to the bottom wall of the inner wall of the cup body 1, and the uniform heat layer injection tube 6 is connected to the inner wall of the cup body 1; the bottom end of the uniform heat layer injection tube 6 is fixedly connected to the bottom of the phase change material injection tube 5. The present application designs the phase change material addition structure into a double-layer sleeve structure, including the phase change material injection tube 5 and the uniform heat layer injection tube 6. The phase change material injection tube 5 is located in the double-layer sleeve structure. The interior of the structure is directly connected to the interior of the temperature control component 4, which is convenient for adding phase change material (negative pressure addition or built-in elbow to extend one end of the elbow into the top of the temperature control component 4 to extract air), ensuring that the phase change material can be accurately and quickly injected into the interior of the temperature control component 4. After the phase change material is added, the phase change material injection pipe 5 is welded and sealed through the sealing piece by laser welding. The uniform heat layer injection pipe 6 is sleeved on the outside of the phase change material injection pipe 5, forming a compact double-layer sleeve structure. A heat-distributing medium (such as pure water) is added to the injection tube 6. After the addition is completed, the pipe mouth of the heat-distributing layer injection tube is welded and sealed through a sealing piece by laser welding. Finally, by cooling the bottom of the inner wall of the cup body 1 and utilizing the phase change characteristics of pure water (the volume expands when it freezes, and the water starts to freeze from the end close to the bottom of the inner wall of the cup body 1), the sealing part (i.e., the brazing sealing part) of the phase change material injection tube 5 and the heat-distributing layer injection tube 6 is stretched open, and the heat-distributing medium is exposed to the vacuum heat-distributing layer to vaporize or liquefy and activate the working ability of the heat-distributing layer.

[0032] In this embodiment, please refer to Figure 1 and Figure 5, a heat conducting sheet 401 is horizontally arranged inside the temperature control part 4, and the heat conducting sheet 401 is multiple and evenly distributed along the height direction of the temperature control part 4 to form a multi-layer heat conducting mechanism, the inner section of the heat conducting sheet 401 is provided with an inner flange, and the outer end is provided with an outer flange, the inner flange is fixed on the outer side of the accommodating groove, and the outer flange is fixedly connected to the inner side of the side wall of the temperature control part 4, and a heat conducting sheet 401 through hole is opened on the heat conducting sheet 401 to facilitate the flow and filling of the phase change material. In this application, by adding multiple layers of heat conducting sheets 401 inside the temperature control part 4, the multi-layer heat conducting sheets 401 not only increase the heat dissipation area, but also Through its unique structural design, it achieves uniform distribution and rapid transfer of heat, making the cooling effect of the overall system more significant. The flange design of the heat conducting plate 401 increases the heat transfer area between the heat conducting plate 401 and the temperature control component 4, further accelerating the heat balance process inside the water cup and achieving rapid and stable cooling. Since heat is conducted and dissipated in a timely and efficient manner, the temperature gradient inside the phase change material is significantly reduced, avoiding the risk of material performance degradation or failure due to local overheating. This not only helps to extend the service life of the material, but also improves the operational stability and reliability of the entire system.

[0033] In this embodiment, please refer to Figure 1 and Figure 2 A hydrophilic layer is arranged in the uniform heating layer, and the hydrophilic layer is made of capillary water-conducting material, and the capillary water-conducting material is sintered copper mesh or sintered copper powder. The present application enhances the capillary force inside the uniform heating layer through the hydrophilic layer 101 made of sintered copper mesh or sintered copper powder, ensuring that pure water (heat-conducting medium) can quickly flow back to the evaporation section through capillary action after evaporation, forming a continuous and stable heat cycle. This self-circulation mechanism does not require external power to achieve continuous and efficient heat transmission, thereby improving the working stability and reliability of the uniform heating layer.

[0034] In this embodiment, please refer to Figure 1 The thermos cup with a phase change material added structure also includes an insulating cover, which is fixed on the top of the cup body 1. This application blocks the convection and conduction of heat between the thermos cup and the outside world through the insulating cover 7 and the vacuum insulation layer 3 of the cup body 1, so that the thermos cup can maintain the water temperature for a long time, reduce heat loss, and further extend the time that the drinking water is at a suitable drinking temperature.

[0035] In summary, the present invention overcomes various shortcomings in the prior art.
