2. Effectively save energy, there is a water seal and lifting mechanism inside the bucket, so there is no steam leakage.

3. The top of the bucket is provided with an overflow vent, which can effectively prevent the phenomenon of steam lock and air blockage (non-condensing high temperature air can also be excluded).
