About a year ago, Xiaomi released a bottle with 316L stainless steel liner, rotating thin mirror technology, heat retention for 12 hours, as well as cold retention and a capacity of 500ml; its price was 99 yuan, about 13 euros at the exchange rate. Well, today the new version of the Mijia Thermos Cup has been released, again priced at 99 yuan, with a similar appearance and the main difference being in the lid.
Xiaomi Mijia Thermos Cup with safer closing system released in China
In particular, a locking system is added to the lid of the Mijia Thermos so as to be able to lock the lid and prevent accidental opening. You will need to move the button to the left to unlock the lid and to the right to lock, in both cases you need to press lightly.
At the same time, Mijia has brought a more intuitive design for opening the lid, according to the brand it is now more difficult for the lid to fall to the ground when we go to drink.
As for the rest, the Thermos also uses 316L stainless steel casing with spin-thin technology, while the vacuum layer uses thin-wall laser welding technology. The capacity is 480ml, which is slightly less than the 500ml of the previous version, and weighs 225 grams, therefore slightly heavier than the 215 grams of the predecessor.
In terms of heat preservation performance on the other hand, a copper-plated reflective layer and vacuum thermal insulation layer design has been adopted, along with a brilliant electrolysis process of the inner tank that reflects the heat radiation back. Hence the copper reflective layer reduces radiation, while the vacuum thermal insulation layer blocks convection and heat conduction and delays heat dissipation. All this brings excellent long-term heat retention and the same with regard to cold.
Finally, going to the real numbers, Xiaomi carried out two 6-hour storage tests of hot drink and cold drink:
- Hot drink test: In an environment with an internal temperature of 20 ℃ ± 5 ℃, the cup was filled with 95 ℃ ± 1 ℃ hot water and closed the lid. After 6 hours, the water temperature was above 68 ℃.
- Cold drink test: in an environment with an internal temperature of 20 ℃ ± 5 ℃, you filled the cup with hot water to 20 ℃ ± 5 ℃ and closed the lid, After leaving it for 6 hours, the temperature of the 'water was less than 10 ℃.
