Abstract

The invention relates to a water cup with a liquid crystal temperature card and a manufacturing method of the water cup, the water cup is provided with the liquid crystal temperature card, and the liquid crystal temperature card is composed of two transparent films and a plurality of polymer dispersed liquid crystal thermosensitive dimming films which are arranged in sequence between the two transparent films. The liquid crystal in the transparent film has different clearing point temperatures; the polymer dispersed liquid crystal thermosensitive dimming films comprise liquid crystals, ultraviolet curing polymers and spacers, wherein the average refractive indexes of the ultraviolet curing polymers are similar to that of the liquid crystals; the liquid crystals are long-pitch cholesteric liquid crystals, the pitch of the liquid crystals is more than 0.5 micron, and when the average refractive index of the liquid crystals is 1.6-1.64, the refractive indexes of the corresponding ultraviolet curing polymers are 1.6-1.64. On the premise that the temperature is displayed, the water cup is lower in cost, does not need electrical devices, and is wider in application range.

Description

technical field [0001] The invention belongs to the technical field of manufacturing a water cup with a temperature display function, in particular to a water cup with a passive non-electronic display liquid crystal temperature card and a manufacturing method thereof. Background technique [0002] Thermos cups are very commonly used household appliances. Ordinary thermos cups, whether it is a glass vacuum interlayer thermos cup or a stainless steel vacuum interlayer thermos cup, because there is no temperature indication function, it will cause tea or hot water drinking in use. Inconvenience. Technology has changed life. In order to make the thermos cup have a temperature display function, various smart cups have emerged as the times require. There are already a number of patented thermos cups with touch screen LCD display on the market. However, because these products are active display devices (displays with battery circuits, etc.), the technology is complicated, the manu...
