Abstract
Description
Technical Field
[0001] The utility model relates to a drinking utensil, in particular to a cup cover with the dual functions of heat preservation and heat dissipation. Background Art
[0002] The vacuum insulated cup has a continuous and efficient heat preservation function. When the water temperature in the cup is high, you cannot drink the water directly. There are generally the following ways to drink water:
[0003] One is to open the cup lid and allow the water in the cup to dissipate heat and cool down to a certain temperature before drinking the water. This method requires waiting for a period of time and cannot be used for immediate drinking.
[0004] The second method is to inject cold water into the cup to cool it down before drinking. This method requires that there is cold water around, which has limitations and will cause the hot water in the cup to not be able to keep warm for a long time.
[0005] The third method is to unscrew the cup lid, pour the water in the cup into the cup lid to cool it down before drinking. Compared with the first method, this method will shorten the waiting time. However, the cup lid of the existing vacuum insulated cup pot is generally a double-layer structure with an interlayer or a vacuum layer. Although the double-layer cup lid with an interlayer has a better heat dissipation and cooling function, its heat preservation performance is poor after it is screwed on the cup body; and the double-layer cup lid with a vacuum layer has a better heat preservation performance after being screwed on the cup body, but its heat dissipation performance is poor. After unscrewing it, pouring hot water in still requires waiting for a certain amount of time for it to cool down. These two types of cup lids cannot achieve both heat preservation and heat dissipation. In addition, the inner layer of the cup lid of the existing vacuum insulated cup pot is sometimes made of plastic. Plastic parts are easily produced by long-term exposure to high-temperature steam environment, which poses a certain hidden danger to the user's drinking water health. Utility Model Content
[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a cup cover with the dual functions of heat preservation and heat dissipation, so as to achieve both heat preservation and heat dissipation performance.
[0007] The utility model is realized through the following technical solutions:
[0008] A cup cover with the dual functions of heat preservation and heat dissipation includes a cup cover body, wherein the cup cover body forms a double-layer structure with an inner cover and an outer cover, the gap between the inner cover and the outer cover forms a heat-insulating interlayer, a separator is provided in the heat-insulating interlayer at the top of the cup cover body, the edge of the separator is fixed on the inner cover, the gap between the separator and the inner cover forms a vacuum cavity, and a gap is left between the top of the separator and the outer cover.
[0009] As a preferred embodiment of the above-mentioned cup lid, the cup lid body includes a top cover body section and an annular connecting section located below the top cover body end. A sealing ring is provided at the bottom end of the top cover body section of the cup lid body, and the sealing ring is used to achieve sealing between the cup lid body and the cup body mouth.
[0010] As a preferred solution of the above-mentioned cup cover, an internal thread structure is provided on the inner side of the annular connecting section of the cup cover body, and a threaded connection between the cup cover body and the cup body is achieved through the internal thread structure.
[0011] As a preferred solution of the above cup cover, the vacuum cavity can completely cover the sealing ring in the horizontal plane.
[0012] As a preferred solution of the above cup cover, the edge of the separator is bent downward to form a bent section, and the separator is fixed to the inner cover through the bent section of the edge.
[0013] As a preferred solution of the above cup cover, the outer cover, inner cover and separator are all made of metal.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] The utility model provides a cup cover with dual functions of heat preservation and heat dissipation. A vacuum chamber is provided on the top of the heat-insulating interlayer of the double-layer cup cover body, so that the cup cover can play a good heat-insulating role when it is closed. After the cup cover is opened and water is poured into the cup cover, the outer cover has a large surface area and a good heat dissipation effect, so the temperature of the water in the cup cover can be reduced relatively quickly, thereby taking into account the dual functions of heat preservation and heat dissipation.

DETAILED DESCRIPTION
[0020] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.
[0021] See also Figures 1 to 3 This embodiment discloses a cup lid with dual functions of heat preservation and heat dissipation, including a cup lid body 1. The cup lid body 1 forms a double-layer structure with an inner lid 2 and an outer lid 3. The gap between the inner lid 2 and the outer lid 3 forms a heat-insulating interlayer 4. A separator 5 is provided in the heat-insulating interlayer 4 at the top of the cup lid body 1. The edge of the separator 5 is fixed to the inner lid 2. The edge of the separator 5 is bent downward to form a bent section 6. The separator 5 is welded to the inner lid 2 via the bent section 6. The gap between the separator 5 and the inner lid 2 is evacuated to form a vacuum chamber 7, and a gap is left between the top of the separator 5 and the outer lid 3.
[0022] The cup lid body 1 includes a top cover section 8 and an annular connecting section 9 located below the top cover end. A sealing ring 10 is provided at the bottom end of the top cover section 8 of the cup lid body 1. A ring groove 12 is provided at the bottom end of the top cover section 8 of the cup lid body 1. The sealing ring 10 is embedded in the ring groove 12. The sealing ring 10 is used to seal the cup lid body 1 and the mouth of the cup body 13. The vacuum chamber 7 can completely cover the sealing ring 10 in the horizontal plane. An internal thread structure 11 is provided on the inner side of the annular connecting section 9 of the cup lid body 1, and the internal thread structure 11 is used to achieve a threaded connection between the cup lid body 1 and the cup body 13.
[0023] The outer cover 3, the inner cover 2 and the separator 5 are all made of metal, such as titanium, stainless steel and the like, thus avoiding the impact of conventional plastic parts on the drinking safety of drinkers.
[0024] When drinking water is not needed, the cup lid is screwed onto the cup body 13, and the sealing ring 10 inside the cup lid contacts the mouth of the cup body 13 to achieve a sealed closure of the mouth of the cup body 13, and the vacuum chamber 7 at the top of the cup lid plays a good heat preservation role, effectively keeping the water in the cup body 13 warm.
[0025] When drinking water is needed, the cup lid is unscrewed from the cup body 13 and the cup lid is inverted to be used as a cup. The hot water in the cup body 13 is poured into the cup lid. The hot water contacts the inner wall of the inner cover 2. The heat is transferred through the non-vacuum heat-insulating interlayer 4 and finally dissipated outward through the outer cover 3. Since the gap between the inner cover 2 and the outer cover 3 forms the heat-insulating interlayer 4, and there is a gap between the top of the partition 5 and the outer cover 3, the outer cover 3 has a large heat dissipation area and a good heat dissipation effect. When the hot water in the cup lid cools down to a suitable temperature, the water can be drunk. The above structure can effectively shorten the cooling time of the hot water, reduce the waiting time of the drinker, and improve the drinking experience. At the same time, the design of the inner and outer double-layer structure of the cup lid body 1 itself can prevent the outer cover 3 on the outside of the cup lid body 1 from being hot.
[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
