Generally speaking, a normal person should not drink less than 2000 ml of water every day. When drinking water, the temperature is too high to exceed 65 degrees, which will lead to mucosal damage. If the mucosa is injured for a long time, it is easy to cause cancer of the esophagus or oral mucosa, so try to keep the temperature of the water at about 55 degrees.

Especially when driving in winter and summer, due to the lack of water caused by the air conditioner in the car, it is necessary to replenish water in time. A cup of hot tea in winter and a cup of ice drink in summer are particularly comfortable.
However, the water temperature of products such as thermos cups is relatively average, and it basically takes a long time to reach the appropriate drinking temperature. Once the water temperature is low, we can only drink cold water in winter.

This cold and warm water cup does not mean that the cup can keep warm and cold, but we provide it with a base that can cool and heat. Through setting, we can control the water temperature at the temperature you want. We can pour mineral water, add a tea bag to turn it into a cup of hot tea, or add freeze-drying to turn it into a cup of cold extraction, or just want a cup of warm water that can be drunk, there is no need to open the lid and wait for the water in the thermos cup to cool down, let alone drink the cold mineral water left on the door panel in the winter morning because there is no hot water.
For the sake of driving safety, we designed the cup cover to be opened with one hand, which can ensure that we have at least one hand on the steering wheel, drinking water without affecting safety, and at the same time keeping our eyes fixed on the front. The black rubber ring can ensure that we will not hurt our hands because the water temperature is too high.
