The present disclosure relates to the technical field of tea
brewing devices, and more particularly, to a beverage
brewing device. The beverage
brewing device comprises a kettle body, a heating disc, and a tea-leaf basket. The heating disc and the tea-leaf basket are located in the kettle body and an air cylinder mechanism is fixed in the kettle body. A moving
piston is arranged in an inner cavity of the air cylinder mechanism, and the
piston is connected to the tea-leaf basket. The air cylinder mechanism is connected to an
air pump, which is used for conveying a driving gas to the air cylinder mechanism. The
piston is driven by the driving gas, thereby driving the tea-leaf basket to move in the kettle body. The air cylinder mechanism may automatically drive the tea-leaf basket to move up and down, achieving a simple structure and a low cost.
