DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The detailed description and technical contents of the present invention will now be provided with reference to the drawings.

[0019] Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the present invention provides a brewing vessel 10 which is used for brewing, cold-brewing or infusing coffee or tea. Further, the brewing vessel 10 comprises a brewing vessel body 11 and an inner structure 12. The brewing vessel body 11 is not the focus of the present invention and can be designed by one skilled in the relevant art based on experience or user requirements, so it will not be described in detail herein. The inner structure 12 is positioned in the brewing vessel body 11, and the inner structure 12 can be selectively taken out from the brewing vessel body 11. The inner structure 12 is provided with a primary filter 121 for performing a primary filtration in the brewing vessel 10, and the primary filter 121 comprises a plurality of through-holes 122 located on the surface of the inner structure 12 as shown in FIG. 3. Further, the brewing vessel 10 includes a secondary filter 13 which is positioned relative to the inner structure 12, and the filtering function of the secondary filter 13 is the same as that of the primary filter 121. In some embodiments, the secondary filter 13 is provided with a filter screen which includes a mesh with filtration holes smaller than the plurality of through-holes 122 of the primary filter 121.

[0020] Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 4, an embodiment of the brewing vessel 10 is described herein. In this embodiment, as an example, the brewing vessel is used to brew coffee. First, the inner structure 12 is filled with coffee grounds 20, and the brewing vessel body 11 is filled with water. After a period of time, the primary filter 121 of the inner structure 12 preliminarily filters the coffee grounds 20 and causes a coffee fluid 22 to seep out, with the coffee fluid 22 containing at least some coffee sediment 21. Thereafter, the secondary filter 13 secondarily filters the at least some coffee sediment 21 out of the coffee fluid 22 via the mesh, so that the filtered coffee fluid 22 is purer as it contains less coffee sediment 21. That is, the secondary filter 13 filters the at least some coffee sediment 21 which failed to be filtered by the primary filter 121, therefore overcoming a flaw of conventional brewing vessels.

[0021] In this embodiment, the secondary filter 13 is positioned between the brewing vessel body 11 and the inner structure 12, and one end of the secondary filter 13 is connected to the inner structure 12. In one embodiment, the secondary filter 13 is positioned at the bottom of the inner structure 12.

[0022] In one embodiment, the brewing vessel 10 further comprises an outer structure 14 enclosing the inner structure 12 therein. The outer structure 14 is connected to one end of the secondary filter 13 which is not connected to the inner structure 12, and the outer structure 14 restricts the coffee fluid 22 flowing out the primary filter 121 to flow through the secondary filter 13 only. Further, the distance between the bottom of the outer structure 14 and the brewing vessel body 11 is greater than the distance between the bottom of the inner structure 12 and the brewing vessel body 11, as shown in FIG. 2. In another embodiment, the distance between the bottom of the outer structure 14 and the brewing vessel body 11 is less than the distance between the bottom of the inner structure 12 and the brewing vessel body 11, as shown in FIG. 3. Additionally, two ends of the secondary filter 13 are respectively connected with the outer structure 14 and the inner structure 12, so that the secondary filter 13 is positioned at a slanted angle.

[0023] Referring to FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, the brewing vessel 10 further comprises a base plate 131 that is connected to the secondary filter 13 and is positioned at the bottom of the inner structure 12. In one embodiment in which the inner structure 12 does not include a sealing cover, the base plate 131 can be implemented as the sealing cover. In one embodiment in which the inner structure 12 includes the sealing cover, the base plate 131 is provided corresponding to the sealing cover. Further, in one embodiment, at least one of the base plate 131 and the bottom of the inner structure 12 contains a connecting structure 132 that is used for assembling the base plate 131 and the inner structure 12 together. In this embodiment, the base plate 131 and the inner structure 12 can be assembled with and disassembled from each other through a spiral design of the connecting structure 132 as shown in FIG. 5.
