Description

Technical Field

[0001] The invention relates to the technical field of daily-use water cups, and in particular to a water cup with a tea-water separation function. Background Art

[0002] The existing tea-water separation cup usually uses the lower part as a space for accommodating tea leaves and tea water, and hangs a basket-type teacup leakage device on the upper part, and separates tea leaves and tea water through the teacup leakage device when drinking. The disadvantage of this teacup is that the tea leaves are soaked for a long time and repeatedly, and the concentration of tea water cannot be controlled, which directly affects the taste and effect of the tea. At the beginning, the tea water is too strong and tastes bitter. After multiple brewing, the tea water is too light and tasteless. In addition, it will lead to the reduction of substances such as vitamin C and amino acids in the tea, reducing the nutritional value, and it is impossible to meet the requirements of tea tasting.

[0003] There are also some water cups that can separate tea and water in the prior art. For example, Chinese patent CN207444738U discloses a water cup, which includes a cup body, a tea-water separation device, and a driving device. A filter plate is provided in the cup body, and filter holes are provided on the filter plate. The tea-water separation device is provided on the filter plate. The driving device is a spiral driving mechanism. The tea-water separation device includes a water retaining plate. The driving device is connected to the water retaining plate. The spiral driving mechanism controls the lifting of the water retaining plate, thereby separating or closing the water retaining plate and the filter plate to achieve the separation of tea and water. This tea and water separation device mainly includes multiple sleeves and springs, etc., which can separate tea and water. When separating tea and water, the water retaining plate is mainly reset to the closed position by the elastic force of the spring. During the process, the water retaining plate moves up and down. When there are tea stems between the water retaining plate and the filter plate, the water retaining plate and the filter plate cannot be completely fitted together, and true tea and water separation cannot be achieved. In addition, this tea and water separation device cannot realize the opening and closing of the filter plate and the water retaining plate at a fixed point. When in use, it can only realize the opening and closing of the through hole by slowly rotating it, which is inconvenient to operate. Summary of the invention
