As we all know, the foot warmer is a kind of low-power heating equipment. At present, there are two kinds of foot warmers on the market: plug-in foot warmers and usb rechargeable foot warmers. There is a difference between the two. The former can't be inserted all the time, and the latter can.
Reason: Plug-in foot heater-direct power supply will lead to unlimited increase of heat during the use of the foot heater, which may easily lead to electric shock and burns, while usb interface will not, because the access ports are generally computers and charging treasures, and the output power of these products is very small, which can only play the role of heat preservation, so they can keep connected.
Correct use of foot warmers with plugs;
Generally, warm shoes are electrically heated by 12V and will not be plugged in when used. Generally, as long as it is not the third product, it is necessary to exhaust it in time, and unplug it immediately after charging, as long as someone is beside it when charging.
How to use the foot warmer?
1. Fill the water with a small funnel. The small funnel must be inserted into the water bag. When the faucet receives water, it must be a trickle, which is slowly poured into the water bag through a small funnel. If the indoor temperature is relatively low, it is best to use warm water, so it is easy to get into the bag.
2. The water in the water bag is 90% full, not too full; Be careful not to let water drop into the power socket, otherwise the indicator light will not light up;
3. Exhaust is very important. After filling with water, hold the water injection port tightly, and slowly squeeze the bag with the other hand until you see the water overflow, and then immediately plug the black plug. This step is very critical and security is at stake.
4. Dry the water on the surface of the foot warmer to ensure that there is no water in the power socket;
5. Gently shake the water injection bag to ensure that the liquid in the bag is shaken evenly;
6. Be sure to observe carefully after plugging in the power supply for charging. If the water injection bag bulges, immediately unplug the power switch, and then exhaust; If it is normal after charging, wait until it is heated before exhausting.
7. After charging, be sure to exhaust the air, and remember to plug the plug tightly to prevent water leakage and burns.
Matters needing attention in the use of foot warmer
1. If there are small protrusions in the bag during use, take out the plug and continue to exhaust.
2. When charging, the foot warmer should be placed in a horizontal place, not in a high place or sideways.
3, the foot warmer can only be used sitting, and must not be used by the whole person standing; The electric heating bag in the foot warmer can be used alone, which can be used to warm both hands and beds.
4. If children use foot warmers, it is best to have adult supervision to prevent unnecessary safety accidents caused by improper use, such as burns and electric shocks.
Analysis of common problems in the use of foot warmer
1, is the foot warmer safe?
The foot warmer has a patented explosion-proof design. When heated and expanded, if there is air inside, it will stop heating up. This is a real explosion-proof foot warmer.
2. Will it leak?
Unique sealing design, no water leakage. The customer should pay attention to the fact that the plug should be slightly inserted into the water injection port (cone) rather than flush with the surface to ensure that there is no gap when it is confirmed that there is basically no air inside and it can be used normally.
3. Why does the indicator light turn on and off?
The foot warmer does not work within the set temperature range, such as 60-70 degrees. Plug-in electric heating to 70 degrees, heating will automatically stop when the lights are turned off; Then the temperature gradually drops, and it doesn't heat up and the light doesn't light up after being plugged in for n times; It is not until it is below 60 degrees, such as 53 degrees, that the lights are turned on and heated normally.
4. Is the indicator light off or warming up?
Just finished pouring tap water, dry the surface, and plug in the lamp, which may be wrong. Tighten the socket of the new product and use a little force to ensure correct insertion.
5. Why is it warm instead of hot?
When there is air inside, it will expand when heated, and the explosion-proof device will start and stop heating up. Solution: when the air expands, take out the plug, grab the socket, insert the small funnel, gently squeeze the surface to exhaust, and then return to normal; Heating can be repeated-exhaust 1-2 times.
