Description

Technical Field

[0001] The utility model relates to the technical field of thermos cups, in particular to a warm water cup based on shape memory alloy. Background Art

[0002] In winter, thermos cups are indispensable in people's daily life. However, most thermos cups on the market focus on long-term heat preservation, which means that from the time boiling water is poured into the thermos cup to the time people drink it, it has always maintained a high temperature and is not suitable for people to drink directly. People need to pour out the water from the thermos cup to cool it down, which is very inconvenient. A warm water cup that can dissipate heat at high temperatures and has excellent heat preservation effect after reaching a suitable temperature will definitely bring more convenience to people's lives. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a warm water cup based on shape memory alloy to solve the above problems.

[0004] Based on the above purpose, the utility model provides a warm water cup based on shape memory alloy, including a cup body, the cup body comprising:

[0005] An inner cup layer, wherein the outer wall of the inner cup layer is sleeved with a shape memory alloy layer, and the inner wall of the shape memory alloy layer is fixedly connected to the outer wall of the inner cup layer;

[0006] An outer interlayer is sleeved on the outer wall of the shape memory alloy layer, and an energy absorbing layer is filled in the outer interlayer;

[0007] When the inner cup layer is cooled to below the transformation temperature of the shape memory alloy layer, the outer wall of the shape memory alloy layer does not contact the inner wall of the outer interlayer, and a vacuum layer is left between the outer wall of the shape memory alloy layer and the inner wall of the outer interlayer.

[0008] As an optional implementation, the shape memory alloy layer contacts the outer interlayer when deformed by heat.

[0009] As an optional implementation, the energy absorbing layer is pure water with a large specific heat capacity.

[0010] As an optional implementation, one of the materials of the outer interlayer and the inner cup layer is 304 food grade stainless steel.

[0011] Beneficial effects of the utility model:

[0012] The utility model utilizes the characteristics that the shape memory alloy layer will be in different shapes at different temperatures and the process is reversible. Through the transition of the shape memory alloy in the outer interlayer between the fully filled and incompletely filled states, the automatic switching of the heat of the water is realized. In conjunction with the energy absorbing layer, the water in the cup body can dissipate heat at a higher water temperature and keep warm at a lower water temperature.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] like Figure 1 , Figure 2 As shown, a warm water cup based on shape memory alloy includes a cup body 1, and the cup body 1 includes:

[0021] An inner cup layer 2, wherein the outer wall of the inner cup layer 2 is sleeved with a shape memory alloy layer 3, and the inner wall of the shape memory alloy layer 3 is fixedly connected to the outer wall of the inner cup layer 2;

[0022] An outer interlayer 4 is sleeved on the outer wall of the shape memory alloy layer 3, and an energy absorbing layer 5 is filled in the outer interlayer 4;

[0023] When the temperature of the inner cup layer 2 is lowered to below the transformation temperature of the shape memory alloy layer 3, the outer wall of the shape memory alloy layer 3 does not contact the inner wall of the outer interlayer 4, and a vacuum layer is left between the outer wall of the shape memory alloy layer 3 and the inner wall of the outer interlayer 4;

[0024] In this embodiment, when the user pours boiling water into the inner cup layer 2, the heat of the boiling water will be transferred from the inner cup layer 2 to the shape memory alloy layer 3. As the temperature rises above the transformation temperature of the shape memory alloy, the shape memory alloy layer 3 will deform and expand. Then the shape memory alloy layer 3 will contact the outer interlayer 4 and transfer the heat to the outer interlayer 4, thereby cooling the boiling water in the inner cup layer 2.

[0025] When the boiling water in the inner cup layer 2 cools down to below the transformation temperature of the shape memory alloy layer, the shape memory alloy shrinks. At this time, a vacuum layer is left between the outer wall of the shape memory alloy layer 3 and the inner wall of the outer interlayer 4, and heat is difficult to transfer to the outer interlayer 4, thereby producing the effect of keeping the water in the cup warm.

[0026] As an optional implementation, Figure 1 As shown, the shape memory alloy layer 3 contacts the outer interlayer 4 when deformed by heat;

[0027] In this way, when the temperature rises above the transformation temperature of the shape memory alloy, the shape memory alloy layer 3 deforms and expands, and then the shape memory alloy layer 3 contacts the outer interlayer 4 and transfers heat to the outer interlayer 4, thereby cooling the boiling water in the inner cup layer 2.

[0028] As an optional implementation, the energy absorbing layer 5 is pure water with a large specific heat capacity;

[0029] In this way, water has a larger specific heat capacity and is low in cost. Absorbing the same amount of heat will result in a smaller temperature rise. The presence of pure water can prevent the outermost layer from being too hot during heat dissipation, making it difficult to hold.

[0030] As an optional embodiment, one of the materials of the outer interlayer 4 and the inner cup layer 2 is 304 food grade stainless steel.

[0031] In this way, 304 food-grade stainless steel can effectively transfer heat and serve as a qualified container.

[0032] A person skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
