The invention relates to a brewing vessel, in particular, a brewing vessel with a secondary filter.
Conventional brewing vessels, which are disclosed in Chinese Patents Nos CN 209090644 U and CN 207285792 U, only perform a single filtration and are unable to filter out coffee sediment in the coffee fluid thoroughly. When the diameter of filtration holes in a conventional brewing vessel is not properly designed, the coffee sediment may not be reliably blocked and will flow out along with the coffee fluid, or the coffee sediment may block the filtration holes and affect the filtering structure's filtering ability, or the concentration of cold brew made in the brewing vessel may be affected.
The main object of the present disclosure is to solve the above-mentioned problems caused by flaws of the conventional brewing vessel.
In order to achieve this object, the present invention provides a brewing vessel which comprises a brewing vessel body and an inner structure positioned in the brewing vessel body, wherein the inner structure is provided with a primary filter. The brewing vessel also comprises a secondary filter positioned relative to the inner structure. The mesh of the secondary filter has filtration holes smaller than that of the primary filter, and the secondary filter filters out at least some coffee sediment that failed to be filtered by the primary filter.
In some embodiments, the secondary filter is positioned at the bottom of the inner structure.
In some embodiments, the brewing vessel comprises an outer structure that encloses the inner structure therein and is connected to the secondary filter, and the outer structure restricts liquid flowing out the primary filter to flow through the secondary filter only.
In some embodiments, the distance between the bottom of the outer structure and the brewing vessel body is greater than the distance between the bottom of the inner structure and the brewing vessel body, and the secondary filter is positioned at a slanted angle.
In some embodiments, the distance between the bottom of the outer structure and the brewing vessel body is less than the distance between the bottom of the inner structure and the brewing vessel body, and the secondary filter is positioned at a slanted angle.
In some embodiments, the primary filter comprises a plurality of through-holes located along the surface of the inner structure, and the secondary filter is provided with a filter screen.
In some embodiments, the brewing vessel further comprises a base plate that is connected to the filter screen and positioned at the bottom of the inner structure.
In some embodiments, of the base plate and the bottom of the inner structure, at least one contains a connecting structure, and the inner structure can be selectively assembled with or disassembled from the base plate via the connecting structure.
Accordingly, the present invention has the following unique characteristics compared with conventional technology: at least some coffee sediment that is failed to be filtered by the primary filter is filtered out by the secondary filter.
The detailed description and technical contents of the present invention will now be provided with reference to the drawings.

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.
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
