Cooling and temperature control cup lid

Abstract

The invention discloses a cooling and temperature control cup lid. The cup lid comprises a cup body and a cup lid body connected to a cup opening of the cup body in a sealed mode, the cup lid body comprises an inner ring body and an outer ring body which are coaxially distributed from inside to outside, an annular gap is formed between the inner ring body and the outer ring body, and a first heatconduction ring and a second heat conduction ring are sequentially arranged in the annular gap from bottom to top. The first heat conduction ring is fixedly connected with the annular gap in a sealedmode, the second heat conduction ring is connected with the annular gap in a sealed and sliding mode, the first heat conduction ring, the annular gap and the second heat conduction ring jointly form avacuum cavity, two iron blocks are symmetrically embedded in the lower end of the second heat conduction ring, and a displacement cavity and an expansion cavity are sequentially formed in the inner ring body from top to bottom. And a second permanent magnet plate is hermetically and slidably connected into the displacement cavity. The cooling and temperature control cup lid has the advantages that the vacuum cup exchanges heat with outside air when the water temperature is high until the water temperature is reduced to be within the suitable drinking temperature range, a vacuum cavity is formed to isolate heat transfer, and the cooling and temperature control effects are achieved.

Description

technical field [0001] The invention relates to the technical field of water cups, in particular to a temperature-lowering and temperature-controlling cup cover. Background technique [0002] People usually use water cups to hold hot water with higher temperature, and need to wait for it to cool naturally to drink in the suitable temperature of the mouth. This method has the following disadvantages: in the early stage of cooling, it is necessary to drink water intermittently to test the temperature, which is more troublesome, and there may be a danger of scalding the mouth; Appropriate temperature is also more troublesome, and it is easy to fall into dust during the exposure process. [0003] In order to solve the above-mentioned problems, we propose a cooling and temperature-controlling cup cover that is naturally cooled to a suitable drinking temperature and then kept warm. Contents of the invention [0004] The purpose of the present invention is to solve the problems...
