Abstract

The utility model relates to a disposable self-cooling and self-heating patch, which relates to the designing and manufacturing technology of self-cooling or self-heating devices. The utility model comprises a cavity, small cavities, connecting components and heat insulating layers, wherein the cavity is divided into the small cavities which are provided with chemicals and the heat insulating layers, and the connecting components are arranged among the small cavities filled with chemicals. The utility model aims at solving the problem of self cooling and self heating of substances in time. When the connecting component is artificially opened, chemicals between the small cavities generate a chemical reaction to absorb heat or release heat to obtain a self-cooling or a self-heating effect. The disposable self-cooling and self-heating patch is attached outside a draw can to make liquid in the draw can cooled or heated. If the disposable self-cooling and self-heating patch is attached outside a wine bottle, the wine in the wine bottle can be cooled or heated; the utility model can also be used in local parts which need to be cooled or heated, and is a good family article for tourism.

Description

Disposable self-cooling is from heat posted

(1) technical field:

The utility model relates to instant self cooling or self-heating Design of device and manufacturing technology.

(2) background technology:

Have now in the bottom of built-in-opener catalyst chamber is set, in catalyst chamber, be divided into two cavitys, in each cavity, load onto chemical substance, between two cavitys connecting device is arranged.After opening connecting device, make two chemical substances in the cavity produce reaction, absorb or emit heat, reach instant self cooling autotermic effect, make material cooling or intensification in the built-in-opener, satisfy people's life requirement, its shortcoming is: built-in-opener is made cavity complex process, waste material.

(3) summary of the invention:

The utility model solves emphatically object is carried out self cooling immediately, autotermic problem.

The technical solution of the utility model is: be made of cavity, little cavity, transom and heat-insulation layer, be separated into little cavity in cavity, chemical substance and heat-insulation layer are housed in little cavity, being equipped with between the little cavity of chemical substance has transom.

The utility model beneficial effect is: when artificially transom being opened, make between the chemical substance between the little cavity chemical reaction takes place, produce neither endothermic nor exothermic, reach self cooling or autotermic effect.These subsides are sticked on outside the built-in-opener, can make liquid cooling or heating in the built-in-opener.As stick on the bottle external enwergy and make wine cooling or heating, also can be applicable to the local place that needs cooling or heating, be the good articles for use of tourism household.

(5) specific embodiment:

Embodiment 1

This disposable self-cooling pastes as Fig. 1, Fig. 2, shown in Figure 3, constitute by cavity, little cavity, transom and heat-insulation layer, in cavity 1, be separated into

loculus body

2,3,4 nitric acid ammonia is housed in loculus body 2, in loculus body 3, water is housed, in outer loculus body 4, heat-insulation layer is housed.Transom is arranged being equipped with on the little cavity of water, transom is to paste adhesive plaster 6 on the opening 5 of little cavity, fixedly backguy 7 on the adhesive plaster, and cavity is drawn in backguy.Instant glue is set outside cavity.Whole subsides are bonded at outside the built-in-opener, open transom, move the water to flow in the nitric acid ammoniacal substance, endothermic heat of reaction is lowered the temperature built-in-opener immediately.Can make people drink ice-cold beverage with these self cooling subsides.

Embodiment 2

Disposable self-cooling pastes, and as shown in Figure 4, the compound of potassium nitrite and potassium nitrate is housed in loculus body 2, and all the other are identical with embodiment 1.

Embodiment 3

Disposable from heat posted, in loculus body 2, calcium oxide is housed, all the other are identical with embodiment 1.
