The second filtering film 311 is made of non-woven fabric or filter paper, and can filter the tea soup for the second time.

The capsule extraction principle of the capsule with the pressure brewing tea is as follows: water flow enters the top cover 2 through the capsule water inlet and is sprayed to tea leaves in the capsule body 1 from the plurality of spraying holes 241 of the spraying structure 24, and the tea leaves are soaked uniformly and rapidly. As the water inflow increases, the pressure in the inner cavity 11 of the capsule body 1 increases gradually, and the pressure of the sealing ball 412 for sealing against the abutment column 4213 increases. When the pressure is increased to a preset value, the plurality of easy-breaking parts 4211 deform, the thin-wall parts of the plurality of easy-breaking parts 4211 are fractured under the continuous pressure action of the sealing ball 412, at the moment, the sealing ball 412 is separated from the upper through hole 4131 of the sleeve 411, the brewed tea soup rapidly flows out from the thin-wall fracture part of the easy-breaking part 4211 through the first filtering membrane 131 and the sealing channel 413 of the sleeve 411, and is discharged from the liquid outlet channel 31 after passing through the second filtering membrane 311 to enter a tea set received below. Meanwhile, due to the small fracture gap of the breakable part 4211, when the tea leaves are brewed for the second brewing, the third brewing and the subsequent brewing, certain extraction pressure is still provided, and the extraction pressure is lower than the first brewing pressure, which is consistent with the brewing process of the original tea leaves.

The utility model discloses not only can satisfy the required difference of different tealeaves and dash and steep pressure, can also satisfy and press the bubble many times and dash and steep, accomplished really that a tea dashes and steeps many times and all can obtain a cup of high-quality tea soup. Has ingenious structure and production feasibility, and makes a contribution to the progress of automatic brewing of the Chinese raw leaf tea.
