The role of getters
The suction piece in the thermos cup is actually a special valve device. When we tighten the cover of the thermos cup, the suction sheet will automatically inflate, forming a sealed air sac, making it difficult for the air inside the thermos cup to flow, so as to achieve the effect of heat preservation. The suction plate seals the body of the cup to prevent hot air and bubbles from leaking out of the mouth or lid, thereby extending the holding time and reducing temperature loss.
Two, the advantages of getters
1. Better insulation effect: the suction sheet can effectively isolate the temperature difference between inside and outside, making the insulation effect more excellent.
2. Stronger leak-proof function: The sealing performance of the suction piece is very good, which can effectively prevent the hot water from overflowing from the mouth of the cup.
3. Stronger exhaust function: A small amount of gas will be produced in the thermos cup, and the suction sheet can help to discharge these gases smoothly.
