Description

A thermal insulation coaster

technical field

The utility model relates to a coaster, in particular to a thermal insulation coaster.

Background technique

In daily life, when people drink beverages such as hot water and coffee, they usually put a coaster under the cup, which can prevent the cup with a higher temperature from directly contacting the table top and protect the cup and the table top. However, since the temperature of the drink in the cup is higher than the ambient temperature, the drink will gradually cool down over time, especially when the temperature is low in winter, such a situation is more obvious. Drinking cold beverages in winter is more irritating to the human body, which is not conducive to human health. When the beverage in the cup becomes cold, people need to get up and then use other electrical appliances to heat it up. The existing heating coasters are usually realized by electric heating, and its structural design is often complicated, and it needs to be plugged in or charged to realize its heating and heat preservation function.

Contents of the invention

The purpose of the utility model is to provide a thermal insulation coaster designed by using the exothermic phenomenon in the chemical reaction process.

The utility model solves the defects that existing thermal insulation coasters have complicated structural design and need to rely on electric energy.

The technical scheme of the utility model is: a thermal insulation coaster, including a coaster body, the coaster body is disc-shaped; the upper opening of the coaster body is provided with a ring-shaped bottom edge; The ring-shaped bottom edge is made of heat insulating material; a circular groove is provided in the middle of the coaster body; the side wall and bottom of the circular groove are composite layer structures; the composite layer structure consists of an inner To the outside are the heat conduction layer, the heating layer and the heat insulation layer; the heating layer is a chemical heating layer, and the chemical heating layer is equipped with chemical preparations for reversible chemical reactions; the bottom of the coaster body is equipped with a non-slip layer. When a hot cup is placed in the groove of the thermal insulation coaster, the heat of the cup is conducted to the chemical heating layer through the heat conduction layer on the side wall and bottom of the groove, and the chemical preparation in the heating layer absorbs a certain amount of heat , an exothermic reaction occurs, and the heat generated by the reaction is transmitted to the cup through the heat-conducting layer, which can keep the cup warm for a certain period of time; when the cup is removed, as the coaster cools, the chemical agent in the heating layer generates A chemical reaction that is reversible with the previous exothermic reaction, allowing the chemical formulation to be used repeatedly.

The heat conduction layer is a metal thin film layer.

The anti-slip layer is a silicone anti-slip layer.

The heat insulation layer is made of polyurethane foam or phenolic resin foam.

The heat insulating material of the annular bottom edge is polyurethane foam or phenolic resin foam, which prevents hands from touching the hot coaster when taking and placing the cup.

The beneficial effects of the utility model are: compared with the prior art, the thermal insulation coaster provided by the utility model uses the heat generated by chemical reactions to keep the cup warm, does not need to use electric energy or charging, and has a very simple structural design.
