Is it safe to charge the water-filled hand warmer?
Because of the different heating devices, the liquid-filled hand warmer can be divided into two types: electrode type and heating wire. On the market, electrode hand warmers account for the vast majority. In the national standard “Safety of Household and Similar Electrical Appliances” promulgated in 2005, it is stipulated that “electrodes should not be used for heating liquids”. Since there is no product standard for hand warmers at present, strictly speaking, hand warmers that use electrode heating It is an unqualified product and has a great safety hazard.
Although both the electric heating wire type electric hot water bottle and the electrode type electric hot water bottle conduct heat through liquid, the water in the hand warmer using the heating wire is not charged, while the water in the electrode type hand warmer is charged. Yes, if the insulation layer of the hand warmer is not thick enough, or if the sealing port is not tight enough to cause water leakage, leakage may occur.
Precautions for safe use:
1. Apply before charging Carefully wipe off the water marks left on the bag body with a dry cloth to ensure dry charging.
2. When charging, do not turn the bag body over so that the power jack is facing down, and it is strictly forbidden to touch the power cord with wet objects.
3. It is strictly forbidden to charge when the water is not full or the air is not exhausted.
4. Be careful not to let water flow into the power supply hole of the bag body, otherwise it will cause a short circuit.
5. Do not pour out the water injected into the body-warming bag, otherwise add water and power on, and the warming bag will not heat up.
6. Do not knead, squeeze or throw the hand warmer bag.
How to fill the electric hand warmer with water
1. Filling with water
First choose the one that matches the funnel spiral Fill the empty bottle with about 1000 milliliters of water (preferably pure water), screw the water storage funnel into the bottle, grab the water storage port of the water bag and lift the water bag, insert the funnel mouth into the water storage port, and add water by squeezing. Remarks: Since there are baffles inside the water storage port, it may be cold and hard in winter. It is recommended that the funnel be inserted into the water storage port without too much force to prevent the funnel tube from breaking.
2. Exhaust
Pull out the funnel, lay the water bag flat on a flat surface, lift the periphery of the water storage port of the water bag, so that the air in the bag is concentrated in the The water injection port, and then gently press the body of the water bag to discharge the air in the bag until there is no air bubbles and water seeps out, and then plug the water plug. The stored water and the heat energy conversion accelerator in the bag are shaken to synthesize the heat-generating agent, which is permanently stored in the bag and must not be poured out.
3. Wipe dry
Wipe the water around the water storage port and the power cord socket and the wet place on the bag to ensure that it is dry before powering on. .
4. Power on
Slide open the power cover, insert the power cord plug into the power cord jack, and then turn on the power, the normal charging time is 8 -15 minutes, but it is better to feel moderate.
Remarks:
1. Insert the power cord jack into the jack of the water bag before turning on the power.
2. After charging, unplug the external power supply first, and then separate the power cord plug and water bag).
