## Abstract

A brewing device includes a supporting ring having a ring body adapted to be disposed on an inner surface of a container, and an inner magnetic member fixed in the ring body. A filter is disposed on and supported by the ring body and is movable along with the ring body. An operator includes an operator body adapted to be disposed on an outer surface of the container and is adapted to be movable relative to the container, and an outer magnetic member fixed in the operator body and magnetically engaging the inner magnetic member. The operator is operable to move the supporting ring and the filter upwardly and downwardly relative to the container.

## Claims

### Claim 1

A brewing device for engaging a container and for brewing a brewable material, said brewing device comprising:
a supporting ring including a ring body adapted to be disposed movably on an inner surface of the container, and an inner magnetic member fixed in said ring body;
a filter disposed on and supported by said ring body and movable along with said ring body; and
an operator including an operator body that is adapted to be disposed on an outer surface of the container and that is adapted to be movable upwardly and downwardly relative to the container, and an outer magnetic member fixed in said operator body and magnetically engaging said inner magnetic member, said operator being operable to move said supporting ring and said filter upwardly and downwardly relative to the container. 20

### Claim 2 (depends on 1)

The brewing device as claimed in claim 1, further comprising a slide rail that is adapted to be fixed to the outer surface of the container and that is adapted to extend along the length of the container, said operator body being slidably engaged with said slide rail.

### Claim 3 (depends on 1)

The brewing device as claimed in claim 1, wherein said ring body has a thickness that gradually decreases from a side that is proximate to said operator to another side that is distal from said operator.

### Claim 4 (depends on 1)

The brewing device as claimed in claim 1, wherein said ring body is formed with at least one airtight space.

### Claim 5

A brewing machine for brewing a brew-able material, comprising:
a container; and
a brewing device including
a supporting ring including a ring body disposed movably on an inner surface of said container, and an inner magnetic member fixed in said ring body,
a filter disposed on and supported by said ring body and movable along with said ring body; and
an operator including an operator body that is disposed on an outer surface of said container and that is movable upwardly and downwardly relative to said container, and an outer magnetic member fixed in said operator body and magnetically engaging said inner magnetic member, said operator being operable to move said supporting ring and said filter upwardly and downwardly relative to said container.

### Claim 6 (depends on 5)

The brewing machine as claimed in claim 5, wherein said brewing device further includes a slide rail that is fixed to said outer surface of said container and that extends along the length of said container, said operator body being slidably engaged with said slide rail.

### Claim 7 (depends on 5)

The brewing machine as claimed in claim 5, wherein said ring body has a thickness that gradually decreases from a side that is proximate to said operator to another side that is distal from said operator.

### Claim 8 (depends on 5)

The brewing machine as claimed in claim 5, wherein said ring body is formed with at least one airtight space.
