Claim Text:
1. A brewing container with a double-layer filtering structure, comprising: a base centrally formed with a through groove, the through groove being provided therein with a plurality of first blocks extending in a radial direction of the through groove; a water-stopping member matching the through groove in configuration, the water-stopping member having a bottom concavely provided with a plurality of inclined guiding surfaces, each said inclined guiding surface having an end located at a bottom end of the water-stopping member and an opposite second end spaced from the bottom end of the water-stopping member by a predetermined depth, the predetermined depth matching a configuration of each said first block such that, when the water-stopping member is positioned in the through groove, each said first block abuts against the second end of a corresponding one of the inclined guiding surfaces, the water-stopping member further having a top provided with a water-stopping rod and with at least one second block, the water-stopping member being vertically penetrated by a plurality of flow channels; a cup having a top formed with an upper opening and a bottom formed with a lower opening, the upper opening being in communication with the lower opening such that a receiving space is formed in the cup, the bottom of the cup being provided with a downwardly extending engaging wall, the engaging wall being provided with at least one engaging groove, wherein when the engaging wall abuts against the base, the engaging groove is engageable with the second block such that the base, the water-stopping member, and the cup jointly form a single unit, and when the first blocks of the base respectively abut against the second ends of the inclined guiding surfaces, a top end of the water-stopping rod seals the lower opening, but the second block does not abut against a top edge of the engaging groove; and a filtering device including a lower filtering element and an upper filtering element, the lower filtering element having a bottom to be mounted at a bottom of the receiving space such that a first filtering space is formed between the lower filtering element and the lower opening, the upper filtering element having a bottom to be mounted at a top of the lower filtering element such that a second filtering space is formed between the upper filtering element and the lower filtering element, wherein when the cup is rotated, the cup drives the water-stopping member to rotate, and with the inclined guiding surfaces respectively abutting against the first blocks, the water-stopping member is pushed by the first blocks and moved upward such that the top end of the water-stopping rod separates from the lower opening, allowing the lower opening to communicate with the flow channels.
