According to the statistics of the China Consumer Association, there are not a few cases of injuries caused by the use of electrode type hand warmers. In fact, as early as 2010, the General Administration of quality supervision, inspection and Quarantine promulgated the special requirements for safe thermal storage electric hand warmers for household and similar electrical appliances, which explicitly stipulates that the sale of electrode type hot water bags that are very easy to cause safety accidents is prohibited. However, it is worrisome that the electrode type hand warmers that are currently banned from sale are still in circulation in the market.
What are the risks of using electrode type heating bags
Professor Ke Baozhong, senior engineer of the Department of electrical control of Guangxi Institute of technology, said that the electrode type heating water bag on the market actually uses the conductive liquid as a resistor through the electrode, and generates heat by heating the resistor; The electric heating wire type hot water bag uses the electric heating wire in the bag as a conductor, generates heat by the electric heating wire, and then conducts heat to the liquid. The electrode type hot water bag relies on the direct contact between the positive and negative electrodes and the liquid to conduct heat. In this way, the solution in the hot water bag is in a conductive state, and the consequences of leakage are very serious.
Professor Ke added that whether it is an electrode type or an electric heating wire type heating bag, there is a temperature controller inside. If the temperature controller fails, there will be two situations: one is to cause the failure of the warm water bag, and the other is to boil the liquid in the warm water bag. Once the internal pressure exceeds the capacity of the warm water bag, it will explode.
39 health.com reminds users to keep their eyes bright when shopping for rechargeable products. They should try their best to choose electric heating wire type or electric heating tube type hand warmers with brand quality assurance, or choose more traditional hot water bags as intimate heating products.
what is the difference between electrode type hand warmer, electric wire type or electric tube type hand warmer
According to the report of Zhongguancun Science and technology channel, it is actually very simple to distinguish electrode type, electric heating wire type and electric heating tube type hand warmers, as long as you touch them with your hands: the inside of electric heating wire type or electric heating tube type water warmers is a mesh wire structure or a U-shaped tubular structure, while electrode type water warmers can generally touch two metal electrodes.
In the process of charging with the warm hand treasure, in case of liquid leakage and excessive expansion, cut off the power supply immediately and stop using it. It is worth noting that the service life of warm hand treasure is generally 1-2 years. If it exceeds this time, it is better to replace it.
