How to exhaust the electric hand warmer? How to open the vent hole of warming hand treasure?

For many little girls, their hands and feet are cold in winter, so the small hand warming treasure is most popular with them. So do you know how to exhaust the charging hand warming treasure? How to deflate the electric hand warming treasure? Learn from Xiaobian!

The liquid in warm hand treasure is a kind of supersaturated solution, the specific composition is unknown. When flipping the sheet metal, friction is actually used to eliminate the unstable 'stable' state of supersaturated solution, so that the solution forms tiny crystal nucleus on the sheet metal surface and grows rapidly, consuming the supersaturated solute in the solution until the solution enters a stable saturated state. This process is exothermic. This is the principle of warm hand treasure.

After knowing the principle of warm hand treasure, many people will ask how to exhaust it. Let's take a look at the detailed operation steps.

1. When the warm hand treasure is charged and heated, just plug in the power for a few minutes, the gas in it will fill the warm hand treasure. The easiest way is to shake the warm hand treasure directly, so the gas will be discharged quickly, and the warm hand treasure will be flat again.

2. Use your fingernails to slowly open the vent hole of the electric heater. The vent is near the plug-in, a plastic nozzle. After that, the gas will be removed quickly, or it can be directly pulled out and heated.

3. When charging and adding, press a thing on the warming hand treasure. The weight should be between 500g and 700g, that is, a thing with a weight of more than half a Jin. This can directly reduce the occurrence of gas and is also conducive to gas discharge. Some hand warmers are equipped with clamps directly, which can not only prevent explosion, but also facilitate exhaust.

Matters needing attention

Exhaust can only be discharged when the hand warmer is not hot. The liquid inside is Gongshui, which is the fastest heated liquid, so it's Gongshui. It's not tap water, so don't overflow too much when exhausting.

Be careful not to hurt yourself.
