Description

Technical Field

[0001] The present application relates to the field of cupware, and in particular to a pulley-type stroke amplification mechanism for a cup cover, a cup cover and a tea brewing cup. Background Art

[0002] A tea brewing cup is a cup used for brewing tea in daily life. In order to improve the convenience of brewing tea, a tea compartment is usually placed in the cup, and tea leaves are placed in the tea compartment to brew tea. However, after the tea leaves are placed in the tea compartment of the tea brewing cup, they are soaked in water for a long time, and the concentration of the tea cannot be well controlled. Long-term soaking is likely to affect the taste of the tea.

[0003] In order to improve the problem of poor control of tea concentration, there are some tea-brewing cups with tea-water separation structures on the market. A magnetic attraction structure and a switch are set on the cup lid of the tea-brewing cup, and a tea compartment that can be magnetically attracted to the magnetic attraction structure is placed in the tea-brewing cup. When in use, the tea compartment is magnetically attracted to the cup lid by turning the cup over, thereby separating the tea compartment from the tea. When it is time to brew tea, the switch on the cup lid is rotated to cancel the magnetic attraction between the cup lid and the tea compartment, and tea can be brewed again.

[0004] However, for some larger tea cups, a tea cup filled with water has a certain weight, and it is not easy to flip the tea cup, which reduces the convenience of using the tea cup. Therefore, the applicant proposes a tea cup with a traction mechanism, which controls the tea compartment by winding the traction belt of the traction mechanism. When it is not necessary to make tea, the traction belt is rolled up along the cover body, so that the tea compartment is separated from the tea; when it is necessary to make tea again, the traction belt is unwound along the cover body, so that the tea compartment falls into the tea and continues to make tea. However, when the traction belt is pulled, the pulling range of the traction belt is large, and the operation convenience is low. Utility Model Content
