1. plays a sealing role: the apron can effectively prevent the glass pot and the pot seat from rubbing due to thermal expansion and cold contraction, thus avoiding water leakage of the pot body.
2. Reduce vibration: the rubber ring can absorb and disperse the vibration generated by the glass pot during heating, which makes the glass pot more stable in use and improves the use experience.
3. Provide support: the rubber ring can provide a certain support force, so that the glass jar can withstand the pressure generated during heating and prevent it from breaking due to unbearable pressure.
I hope the above answers can help you. Please feel free to let me know if you have any other questions.
