Description

Technical Field

[0001] This utility model relates to the field of liquid container technology, and in particular to a double-layer vacuum heat-reflective insulated cup. Background Technology

[0002] As a portable insulated container, the core principle of a thermos flask lies in its structural design and material selection to slow down heat loss through conduction, convection, and radiation, thereby achieving its heat preservation or cold preservation function. Early insulated containers mostly used single-layer metal materials, which had limited heat preservation effects; modern thermos flasks generally use a double-layer stainless steel structure, significantly reducing the impact of heat conduction and convection by creating a vacuum between the inner and outer layers, making them the mainstream product in the market.

[0003] Double-walled vacuum insulated cups effectively block heat conduction and convection through the vacuum layer between the inner and outer layers, significantly improving their heat retention performance. While the vacuum layer suppresses conduction and convection, it cannot completely block heat radiation. Experiments show that in high or low temperature environments, heat can still penetrate the vacuum layer through infrared radiation, causing the heat retention effect to rapidly diminish over time. The current drawback of double-walled vacuum insulated cups is that their design only optimizes for heat conduction and convection, neglecting the crucial impact of heat radiation on heat retention performance. Because there is no medium in a vacuum environment, heat radiation becomes the primary heat dissipation pathway. Utility Model Content

[0004] The technical problem to be solved by this invention is heat loss caused by thermal radiation penetration. This invention provides a double-layer vacuum heat-reflective thermos cup to solve the above problem.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a double-layer vacuum heat-reflective thermos cup, including an inner liner, an outer liner and a cup lid. The inner liner is fixedly connected to the top of the outer liner, and the cup lid is threadedly connected to the top of the outer liner. A metal coating layer is laid on the inner side of the outer liner. A cavity is provided on the inner side of the cup lid, and the metal coating layer is laid in the cavity. The metal coating layer is used to reflect infrared radiation. A pressure relief component is provided in the cup lid to connect the inside and outside of the inner liner.

[0006] A further preferred embodiment of this utility model is as follows: the pressure relief assembly includes an air supply pipe, which is slidably connected inside the cup lid. The bottom of the air supply pipe passes through the bottom plate of the cup lid and the metal coating layer laid inside. A pressure relief port is opened on the side wall of the cup lid. Both the upper and lower ends of the air supply pipe have exhaust ports, and the air supply pipe is hollow inside to connect the two exhaust ports. The upper exhaust port is connected to the pressure relief port, and the lower exhaust port is connected to the inner liner. An operating plate is connected to the top of the pressure relief port. A return spring is sleeved on the upper end of the air supply pipe. One end of the return spring is connected to the cup lid, and the other end is connected to the operating plate.

[0007] A further preferred embodiment of this utility model is: a hollow shell is provided on the outer liner at a distance, the top end of the hollow shell is fixedly connected to the outer liner, and the heat insulation cotton is filled in the gap between the hollow shell and the outer liner.

[0008] A further preferred embodiment of this utility model is: an anti-accidental touch ring is connected to the top of the cup lid, and the anti-accidental touch ring surrounds the operation panel.

[0009] A further preferred embodiment of this utility model is as follows: a telescopic pad is provided inside the anti-accidental touch ring, the top of the telescopic pad is connected to the outer ring of the operation plate, the bottom of the telescopic pad is connected to the top surface of the cup lid, and the telescopic pad wraps around the reset spring.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] This embodiment mainly describes the structure of the thermos cup, as follows: A double-walled vacuum heat-reflective insulated cup, such as Figures 1-4 As shown, the device includes an inner liner 1, an outer liner 2, a metal coating layer 3, a cup lid 4, and a pressure relief assembly. The inner liner 1 and the outer liner 2 are fixedly connected at their top ends. The interlayer between the inner liner 1 and the outer liner 2 is vacuumed during connection. The function of this vacuum environment is to block the heat conduction and convection of the air medium, which significantly reduces the efficiency of heat transfer through the physical medium. The cup lid 4 is threadedly connected to the top of the outer liner 2. The inner side of the outer liner 2 is covered with a metal coating layer 3. The inner side of the cup lid 4 is provided with a cavity, and the cavity is covered with a metal coating layer 3. The metal coating layer 3 is used to reflect infrared radiation and reduce heat transfer through radiation. The cup lid 4 is provided with a pressure relief assembly for connecting the inside and outside of the inner liner 1.

[0020] like Figure 3 and Figure 4As shown, the pressure relief assembly includes an air supply pipe 51, an operating plate 7, and a return spring 8. The air supply pipe 51 is slidably connected inside the cup lid 4. The bottom of the air supply pipe 51 passes through the bottom plate of the cup lid 4 and the metal coating layer 3 laid inside. The side wall of the cup lid 4 has a pressure relief port 5. Both the upper and lower ends of the air supply pipe 51 have exhaust ports 6. The air supply pipe 51 is hollow inside to connect the two exhaust ports 6. The upper exhaust port 6 is connected to the pressure relief port 5, and the lower exhaust port 6 is connected to the inner liner 1, realizing the one-way discharge of high-pressure gas from the inner liner 1 to the outside. The top of the pressure relief port 5 is connected to the operating plate 7. The upper end of the air supply pipe 51 is fitted with a return spring 8. One end of the return spring 8 is connected to the cup lid 4, and the other end is connected to the operating plate 7, realizing the automatic reset of the air supply pipe 51 and automatically closing the air pressure channel after pressure relief.

[0021] like Figure 1 and Figure 2 As shown, it also includes a hollow shell 9 and heat insulation cotton 10. The hollow shell 9 is sleeved on the outer liner 2 at intervals. The top of the hollow shell 9 is fixedly connected to the outer liner 2. The gap between the hollow shell 9 and the outer liner 2 is filled with heat insulation cotton 10 to form an external heat insulation layer, reducing the influence of external temperature on the conduction of heat to the outer liner 2.

[0022] like Figure 1 and Figure 3 As shown, it also includes an anti-accidental touch ring 11. The anti-accidental touch ring 11 is connected to the top of the cup lid 4 and surrounds the operation panel 7.

[0023] like Figure 3 As shown, it also includes a telescopic pad 12. The telescopic pad 12 is provided inside the anti-accidental touch ring 11. The top of the telescopic pad 12 is connected to the outer ring of the operation plate 7, and the bottom of the telescopic pad 12 is connected to the top surface of the cup lid 4. The telescopic pad 12 wraps around the reset spring 8.

[0024] like Figure 3 As shown, it also includes an identification card 13, which is connected to the top surface of the operation panel 7.

[0025] like Figure 3 As shown, it also includes a sealing gasket 14. The bottom of the air supply pipe 51 is connected to the sealing gasket 14. The sealing gasket 14 fits with the opening at the bottom of the cup lid 4 to form a secondary sealing structure.

[0026] like Figure 1 As shown, it also includes an anti-slip pad 15, and the cavity shell 9 is covered with an anti-slip pad 15.

[0027] After the user pours hot water into the inner liner 1 and tightens the lid 4, the heat preservation mechanism is immediately activated: the vacuum jacket blocks heat conduction and convection through the air medium, and the metal coating layer 3 further suppresses heat radiation transmission by reflecting infrared radiation. At this time, the cavity shell 9 and the insulation cotton 10 form a double heat insulation barrier, reducing the influence of the external environment on the temperature of the outer liner 2, keeping the outer liner 2 and the metal coating layer 3 at a relatively stable temperature, and preventing the outer liner 2 from becoming too cold and accelerating the loss of internal heat.

[0028] When water vapor evaporation causes the air pressure in the inner liner 1 to rise, the lid 4 is pushed upwards slightly by the internal air pressure. This action is converted into a tight seal on the top of the outer liner 2 through the threaded structure, indirectly enhancing the sealing effect between the lid 4 and the outer liner 2. However, this phenomenon also means that greater frictional resistance needs to be overcome when loosening the lid 4 later.

[0029] Before drinking, a pressure relief operation must be performed: the user presses down the control panel 7 vertically, and the identification card 13 simultaneously indicates the correct operating direction through text or images. The control panel 7 drives the air supply pipe 51 to slide downwards, with the bottom of the air supply pipe 51 inserted into the area above the liquid surface of the inner tank 1, while simultaneously compressing the return spring 8 and the telescopic pad 12. At this time, the exhaust port 6 at the bottom of the air supply pipe 51 is connected to the inside of the inner tank 1, and the exhaust port 6 at the top forms a passage with the outside air through the pressure relief port 5, allowing the high-pressure gas in the inner tank 1 to be discharged through the hollow channel of the air supply pipe 51. During operation, the anti-accidental contact ring 11 physically limits the control panel 7 to prevent tilting and avoid liquid leakage.

[0030] After the operating plate 7 is released, the elastic potential energy of the return spring 8 is released, pushing the operating plate 7 back and causing the air supply pipe 51 to slide upwards and reset along the inner wall of the cup lid 4. When the air supply pipe 51 moves to the initial position, the upper and lower walls of the cup lid 4 respectively block the exhaust ports 6 at both ends of the air supply pipe 51, cutting off the internal and external air pressure exchange channel. At the same time, the sealing gasket 14 at the bottom of the air supply pipe 51 fits tightly with the opening at the bottom of the cup lid 4, forming a secondary sealing structure and completely blocking the liquid leakage path.

[0031] After depressurization, the user can easily unscrew the cup lid 4. The anti-slip pad 15 on the outside of the cup lid 4 increases friction to help the user easily complete the opening and closing action. At the same time, the continuous heat insulation effect of the cavity shell 9 and the heat insulation cotton 10 ensures that the cup body temperature is suitable during operation, improving the user experience.
