Solution of yin-yang cup

As we all know, because adults and children have different requirements for drinks, for example, adults prefer tea and children prefer drinks. If adults and children share a water cup, it is easy to infect children with bacteria, but it is inconvenient for adults to take two cups when they go out with their children. Yin-yang cup is a container with two cups, which effectively solves the above problems and has been widely used in daily life. The existing yin-yang cup comprises a cup body, wherein a placing cavity is arranged in the cup body, and a partition plate is arranged in the placing cavity, and the partition plate divides the placing cavity into an upper cavity and a lower cavity; The top and bottom ends of the cup body are respectively provided with an upper inlet and a lower inlet, and the upper inlet and the lower inlet are respectively provided with an upper cup cover and a lower cup cover, which are respectively communicated with the upper cavity and the lower cavity; When using the existing yin-yang cup, adult drinks are introduced into the upper cavity from the upper air inlet, and children's drinks are introduced into the lower cavity from the lower air inlet after the upper cup cover is screwed with the upper air inlet, and then the lower cup cover is screwed with the lower air inlet to realize the classified placement of adult and children's drinks; In use, it is found that the upper cavity and the lower cavity are inconvenient to clean because the partition plate is obliquely arranged in the placing cavity, which leads to low reliability in use; And its thermal insulation performance is poor, which affects the use effect and leads to low practicability.
