Detailed Description

As shown in figure 1 and figure 2, the heat-insulating cup sleeve made of the phase-change material consists of an elastic groove silica gel inner sleeve 1, a strip-shaped gas-liquid phase change capsule 2 and an annular silica gel cup sleeve 3, and the production and processing method of the heat-insulating cup sleeve is described as follows:

1. manufacturing an elastic groove silica gel inner sleeve 1: uniformly stirring liquid silica gel and a curing agent at a ratio of 50: 1 at normal temperature, opening a special die for the customized elastic groove silica gel inner sleeve, pouring the uniformly stirred silica gel liquid into a die box, curing at 60-80 ℃ for 2 hours, and taking out to prepare an elastic groove silica gel inner sleeve 1;

2. preparing a strip-shaped gas-liquid phase change capsule 2: manufacturing a phase change capsule 4 empty shell on a special silica gel capsule forming machine, putting a solid-state liquid-phase material into the empty shell under a low-temperature condition, and sealing a gap at the periphery of the empty shell;

3. manufacturing an annular silica gel cup sleeve 3: manufacturing an annular silica gel cup sleeve 3; uniformly stirring liquid silica gel and a curing agent at a ratio of 50: 1 at normal temperature, opening a special mould for the annular silica gel cup sleeve, pouring the uniformly stirred silica gel liquid into a mould box, curing at 60-80 ℃ for 2 hours, and taking out to prepare an annular silica gel cup sleeve 3;

4. assembling a cup sleeve: assembling the manufactured elastic groove silica gel inner sleeve 1, the strip-shaped gas-liquid phase change capsule 2 and the annular silica gel cup sleeve 3; firstly, coating a layer of adhesive in each vertical strip-shaped groove of the elastic groove silica gel inner sleeve 1, vertically arranging strip-shaped gas-liquid phase change capsules 2 one by one and bonding the capsules in the vertical strip-shaped grooves, coating a layer of adhesive on the outer surfaces of the strip-shaped gas-liquid phase change capsules 2 after firm bonding, sleeving the annular silica gel cup sleeve 3 outside the strip-shaped gas-liquid phase change capsules 2 which are bonded with the elastic groove silica gel inner sleeve 1 into a whole, and manufacturing the heat insulation water cup sleeve made of the phase change material after the inner side of the annular silica gel cup sleeve 3 is firmly bonded with the outer surfaces of the strip-shaped gas-liquid phase change capsules 2.

Referring to fig. 2, fig. 3, fig. 4 and fig. 5, the invention provides a heat-insulating cup cover made of phase-change material, and the swimming method and the working principle process thereof are explained as follows:

when the temperature is lower than 40 ℃ in a normal temperature environment, the phase change material stored in the phase change capsule presents a small solid volume, the strip-shaped gas-liquid phase change capsule 2 is flatly attached to the annular silica gel cup sleeve 3 in a large area, when 100 ℃ boiled water is poured into the cup, heat is conducted to the strip-shaped gas-liquid phase change capsule 2 through the cup wall, the temperature is raised to be higher than 60 ℃, the phase change reaction is generated after the phase change material in the phase change capsule absorbs heat, the phase change material is converted from the original solid state to a liquid state, the temperature is continuously raised to be higher than 60 ℃ to 80 ℃, the liquid phase change material is converted into a gas state and sublimated into a gas state, the capsule volume is rapidly expanded, the flat state is expanded into a circular state, the annular silica gel cup sleeve 3 is jacked, the attaching area is reduced by two thirds, an air gap is generated, most of the heat transmitted from the surface of the bottle wall can not be transmitted to the upper surface of the annular, the accumulated heat is not conducted outwards through the annular silica gel cup sleeve 3 any more, and the comfortable effect that the cup sleeve is not hot when being held by a hand is achieved.

When the temperature of water in the cup is reduced to be below 80 ℃, the phase change material in the strip-shaped gas-liquid phase change capsule 2 generates reverse phase change reaction after heat dissipation and is gradually changed from a gas state to a liquid state, when the temperature of water in the cup is reduced to be below 60 ℃ to ambient temperature, the phase change material is gradually restored to a solid state, the volume is reduced to be the original size, the strip-shaped gas-liquid phase change capsule 2 is changed back to a flat state, the contact area with the surface of the annular silica gel cup sleeve 3 is increased, when boiled water is poured into the cup again, the solid-liquid-gas three-phase circulation process is continuously repeated, and the circulation is repeated, so that the design purpose that the cup sleeve is not hot when the cup.
