Novel electric hot water bag

Abstract

The invention discloses a novel electric hot water bag, comprising a water bag, an air vent, a liquid and a power plug, wherein the water bag is composed of an inner layer and an outer layer; a heater arranged at the inner layer of the water bag is connected with a conductive jack arranged at the outer layer through a lead; a timer is arranged between the heater and the conductive jack; a thermal insulating fabric layer is filled between the inner layer and the outer layer of the water bag; and the thermal insulating fabric layer is made of a far-infrared negative oxygen ion material. The novel electric hot water bag is characterized in that the timer is arranged on the heater to achieve the safety and explosion prevention purposes. The thermal insulating fabric layer filled between the inner layer and the outer layer of the water bag is capable of slowing down heat dissipation and extending the use time of the hot water bag, thereby achieving the effect of long-time heat preservation. Besides, the novel electric hot water bag is simple in structure, safe, convenient and practicable.

Description

technical field [0001] The invention relates to a hot water bag, in particular to a novel electric hot water bag with good thermal insulation effect and safe use. Background technique [0002] In the cold winter, people often use hot water bags to keep warm, or use hot water bags to compress wounds, massage the body, etc. With the development of science and technology, a new type of hot water bag, namely electric hot water bag, has appeared on the market. It can heat the heat-prone substances inside through an electric heating device, eliminating the trouble of repeatedly pouring hot water, so it is more and more popular among people. But there are following disadvantages in the electric hot water bag sold on the market: [0003] 1. The shell of the existing electric hot water bag is generally made of PVC nylon. During repeated charging and use, it is easy to cause the water bag to continue to be heated due to the failure of the temperature controller during repeated charg...

AI Technical Summary

Problems solved by technology

[0003] 1. The shell of the existing electric hot water bag is generally made of PVC nylon. During repeated charging and use, it is easy to cause the water bag to continue to be heated due to the failure of the temperature controller during repeated charging. At the same time, pressure is generated inside the water bag. When the pressure exceeds the water bag When the pressure limit that it can withstand, the water bag will explode and cause a safety accident

[0004] 2. The electric hot water bag uses heat transfer to warm people. Due to the limited heat source in the bag, the temperature supplied to the human body by the electric hot water bag will change from high temperature to low temperature, and finally cool down gradually, and the heat preservation effect is poor.
