It's getting colder and colder. Many families are using hot water bags. Now there is a kind of electric water bag on the market. It will be hot after being electrified for a while, so there is no need to boil water. But this kind of electric water bag will have gas expansion phenomenon when it is electrified and heated, so it needs to release some air to be safe. How to exhaust properly?
How to exhaust the electric water bag
1. When it is found that the charging hot water bag is heated after charging, if it is too drum or there is a "Dong Dong" sound when shaking, it needs to exhaust.
2. The exhaust port is usually near the plug-in. There is a plastic nozzle with the word "exhaust" written on it. The word is very small and needs to be carefully read.
3. When deflating, put the plastic nozzle upward and gently pry it out with a small stick (blunt head, preferably oral liquid pipette, screwdriver, etc.).
4. At the same time, gently pressing the bag will make the sound of deflating. If some liquid comes out of the bag, it will not need to be put again until the next time there is air.
There are two kinds of electric water bag, each with different working principles
1. Electrode type hot water bag
The electrode type hot water bag has serious safety risks: because the electrolyte solution is in the charged working state, once the leakage occurs, there will be electric shock risk; in addition, because the electrode is directly in contact with the liquid, the efficiency of electric energy conversion into heat energy is high, and there is no temperature control device. After the hot water bag is electrified, it will easily explode.
2. Electric wire hot water bag
The heating body of the electric heating wire type hot water bag is not in direct contact with the liquid, and the coil is also separated by the insulator and the liquid to ensure the safety.
Precautions for using electric water bag:
1. If it is just exhausted, dry it before charging.
2. When charging, don't put it in the quilt, on the easy burning objects, or the place where the water may flow to the power supply (to prevent the leakage of the water flowing to the place after the hot water bag bursts).
3. When charging, do not leave, in case of any situation, cut off the power supply.
4. Because want to charge, have hot water, so quality wants to assure, had better be to buy electric heating wire type hot water bag in regular market, and want to keep good invoice.
5. If there is any problem, please stop the electric water bag immediately.
Purchase of electric water bag:
The working principle of the electric heating water bag is to heat the internal liquid through the heating body. The heating body is divided into electrode type and electric heating wire type. The electrode type electric heating water bag is easy to cause short circuit or explosion after being electrified due to its direct contact with water and no temperature control device. It is easy to leak electricity after bursting. It has been confirmed that there is a serious potential safety hazard and has been banned from sale.
How to identify whether the electric water bag is electrode type? As long as you pinch the heater in the hot water bag, if the heater is not big, it is electrode type. If you can obviously touch a plastic coil device with a diameter of 78 cm, it is the electric heating wire hot water bag. When choosing, choose to have overheat, overpressure protection device.
