I. What’s the matter with the hot water bag when it is charging?
There are three types of hot water bags, one is an electric heating wire type electric heating bag, and the other is an electrode type There are electric heating bags, and there is also an electric heating cake. Among them, the electrode type electric heating bag has been banned due to the great potential safety hazard.
The buzzing sound of electric heaters is generally seen in liquid electric heaters, because the liquid inside boils after charging. During the heating process, it is normal for the electric heating wire type electric heater to expand slightly, or to emit a heating sound, which can be improved by shaking the bag body slightly, and at the same time, the heat storage can be increased evenly. If you are using an electrode type electric heater, it is recommended to cut off the power supply as soon as possible to avoid safety accidents.
Is it normal for the hot water bottle to charge and expand?
The reason for the charge and expansion of the hot water bottle is that the water inside the hot water bottle is not our ordinary domestic water, but is mixed with impurities The water becomes the conductor of electricity, and if the water in the bag contains too many impurities, the excess impurities will be electrolyzed to generate a large amount of gas when the concentration is high, which will cause the hot water bag to expand. To put it simply, a stable chemical reaction will generate precipitates and gases, so it is not difficult to explain that the charging hot water bag will bulge after a period of time.
Therefore, it is normal for the hot water bottle to charge and expand, as long as the expansion is not too severe, it will not affect the use. However, it should be noted that if the hot water bottle expands greatly when charged, it is not a normal phenomenon, and the power supply needs to be disconnected in time.
3. How long is the life of the electric heating bag?
There is a thermostat inside the electric heating bag. It may fail. If the thermostat fails, the electric hot water bottle may explode due to too long charging time, so the service life of the hot water bottle is generally not long.
The service life of a regular hand warmer is generally 2 to 3 years, and it is more appropriate to replace it after two years. That is to say, the hand warmer is not a seasonal item and does not need to be replaced every year. , the hand warmer bought last year can be used again this year if it is properly kept. Of course, for the sake of safety, it is not impossible to change one every year, but it is best not to use the hand warmer for more than 3 years, so as to avoid accidents due to expired use.
However, it should be noted that due to a large number of non-certified products and inferior electric hot water bottle products on the market, many electric hot water bottles do not have additional outer packaging, and the material ranges from 10 yuan to 40 yuan. It is basically worn out in one winter, and some even break down in less than one winter. It is rarely used for the second year. This kind of electric hot water bottle is more considered to be a seasonal product that is changed every year, and it is not recommended to use it. .
In addition, I would like to remind everyone here that qualified hand warmers have outer packaging, and the outer packaging is marked with the manufacturer, factory address, contact number and 3C product certification mark, etc. For the sake of safety, it is better to buy Qualified products are better.
