Problems solved by technology

The main disadvantage of this kind of electric hot water bag is that the gas generated when it is heated by electricity will not be discharged automatically, and the cover plug on the water injection port on the surface of the hot water bag must be manually opened to release the gas, which is inconvenient and unsafe. The gas inside increases with repeated heating, and the pressure is too high to cause the hot water bag to burst, causing an accident
[0003] As the improvement of the above-mentioned hot water bag, Chinese utility model patent: ZL02223120.X discloses a kind of "explosion-proof electric hot water bag" (its publication number: CN

Abstract

This invention relates to anti-explosion electrical water bag, which comprises sealed soft bag, liquid as memory medium and heating element, wherein, the said bad is set with electrical socket with protection switch and ring; the protection switch is connected to the heating element; one end of string is fixed on bag inner wall with other end connected to second end of protection switch and push bar.

Description

Technical field [0001] The invention relates to an electric hot water bottle, in particular to an explosion-proof electric hot water bottle. Background technique [0002] At present, the commercially available electric hot water bottle has a sealed bag made of PVC nylon silk. The bag is filled with water and two rod-shaped heating electrodes are placed in the bag. The electrodes are connected to a power supply socket on the surface of the hot water bottle. One of the electrodes There is also a temperature limit relay connected in series with the power supply socket. After the power is turned on, the water between the two electrode rods has a certain resistance. The water acts as a load to convert electrical energy into heat, and the water temperature rises. When the water temperature reaches the upper limit temperature of the temperature limit relay , The temperature limit relay will automatically cut off the power to complete a work process. The main disadvantage of this kind of...
