The exhaust hole of the hot water bottle is used to discharge the air inside, and the new buy does not need to vent, open the exhaust hole to discharge excess gas when exhaust is.

When the hot water bottle is heated, water steam is generated, and it has long been long. It is much larger than when I bought it. Especially when heating, it will be rising, because it is full of air, this time needs it. It's easy to get dangerous.

When opening the exhaust hole exhaust, pay attention to the pressing air, do not force too much, such as the water level, stop pressing, otherwise it will extrude the water inside. To extrude the air inside regularly, it is prone to hazard.
