Embodiment Construction

[0007] In winter, the electric thermal bag is widely used, and it is convenient to heat and keep warm for a long time. There are also many deficiencies: for example, due to weak links such as power connectors and water injection ports, when the temperature of the thermal bag changes greatly, there must be air and water leakage and entry. When the heat preservation bag is at low temperature, the heat storage material inside the heat preservation bag shrinks in volume, forming a negative pressure, which will inhale air. If the air is not released from the water injection port at any time, it will easily explode due to expansion during electric heating, which will cause electric shock or A scald accident occurs, and the safety is poor; after the heat preservation bag is heated, the heat storage material expands, the internal pressure increases, and the internal moisture also leaks, so water injection is often required. Repeated deflation and water injection will make the water in...

Abstract

The invention discloses a warm keeping bag. The warm keeping bag is composed of a warm keeping bag body and heat storage materials surrounded by the warm keeping bag body in a sealed mode. The warm keeping bag can be heated externally and is sealed. The heat storage materials of the warm keeping bag are composed of water, grease, magnetic powder and electric conduction metal powder, and can be heated by heat sources such as an external induction cooker, a microwave oven and an infrared bulb or be heated by being exposed in the sun, and then the heat storage materials can reach the needed temperature. The sealed warm keeping bag is not provided with a circuit, so that no circuit fault occurs; weak links such as filling holes and electric connectors do not exist, so that water filling and air exhaust are not required. The sealed warm keeping bag which is heated by the external heat sources has the advantages of being simple in structure, low in price, safe, reliable, long in service life, convenient and comfortable to use, capable of being widely used for living heating and medical care, and the like.

Description

technical field [0001] The invention relates to a warm-keeping article for daily life and medical treatment, in particular to a warm-keeping bag heated from the outside. Background technique [0002] Electric thermal bags are widely used, convenient for heating, and keep warm for a long time. Also there are many deficiencies: due to being provided with weak links such as power connectors and air vents, when the temperature of the thermal bag varies greatly, there must be air entering and moisture leakage. Air will be sucked in at low temperature, and it is often necessary to release the air; internal moisture will also leak at high temperature, and water injection is often required; repeated deflation and water injection will make the water injection hole less tightly sealed. Both the circuit and the connector are in the corrosive electro-hydraulic, which often breaks down, shortens the life, and virtually increases the cost of use. Although a thermal bag heated from exter...
