Background technique

In addition to the rich aroma and delicate flavor, coffee has the effect of boosting the spirit. The quality of life of modern people has improved, and the level of food, clothing, housing and transportation in daily life has gradually increased. Therefore, the roasting degree and brewing method of coffee are exquisite. The pursuit of coffee has become a trend. Among them, hand-brewed ground coffee with a mellow and rich flavor is the most popular among the public. In the prior art, hand-brewing coffee is to use a filter product placed on a filter cup holder, put the ground coffee powder into the filter product of the filter cup holder, and then pour hot water into the filter product in the filter cup holder Inside, the hot water slowly passes through the coffee powder to become coffee liquid, the coffee liquid flows out of the filter product and drips into the cup, the coffee powder forms coffee grounds and stays on the filter product, and then the filter product and coffee grounds are taken out from the filter cup holder.

Filter paper, filter cloth and filter screen are commonly used in the aforementioned filtering products. Among them, the filter paper and filter cloth have small pores, and the coffee grounds will concentrate on the bottom of the filter paper and filter cloth, and block the pores of the filter paper and filter cloth. , causing the extraction time to be too long, making the coffee liquid too strong and bitter, and the filter paper and filter cloth will absorb and filter the oil in the coffee liquid, so that the taste of the coffee liquid will lose its smooth taste and appear more sour. , the filter paper is a one-time commodity, so the filter paper will be consumed every time you make coffee by hand, causing the problem of garbage.

In addition, there are two main types of filter mesh, woven and etched. The woven filter mesh is woven from the warp and weft of a plurality of steel wires, and a rectangular mesh is formed between the warp and the weft. The mesh of this type of woven filter is large. Not only the filtering effect is not good, but some coffee grounds will flow down through the mesh during filtering, so that the coffee liquid contains fine powder. It is not easy to clean, and it is easy to accumulate residues or dirt, which makes the overall appearance easy to appear dirty and unsanitary, and makes it difficult for users to use.

The etching filter is made of a sheet-shaped stainless steel material with a plurality of holes by etching technology, and then the stainless steel sheet with countless holes is formed into a conical shape; however, due to the practical limitations of etching technology, the holes formed can no longer be formed. It is further refined, and its holes are evenly arranged, so its filtering effect is also not good. During filtering, some coffee grounds will flow down through the holes, so that the coffee liquid contains more fine particles. When drinking the coffee liquid , the throat will be attached to the fine particles, and there is an uncomfortable feeling.

SUMMARY OF THE INVENTION

In view of the above-mentioned shortcomings of the filter products used for filtering coffee in the prior art, the present invention provides a coffee filter cup, the coffee filter cup is in the shape of a cone with a large upper and a small lower, a conical surface is arranged on the periphery, and a lower end of the conical surface is arranged with a Bottom cap, the conical surface is provided with a plurality of top-to-bottom forward lines and a plurality of top-to-bottom reverse lines, and is divided by the plurality of forward lines and the plurality of reverse lines. a lead-out space, a V-shaped area tapered from top to bottom is formed in the lower part of the lead-out blocks, and a plurality of holes formed by etching are arranged in the lead-out blocks. The outward-facing side of the grooves is provided with a forward guide groove, and the outward-facing side of the spaced reverse grooves is provided with a reverse guide groove, and the forward guide groove intersects with the reverse guide groove to form a plurality of continuous guide grooves. Type guide channel.

The main purpose of the coffee filter cup of the present invention is that it can obtain a better filtering effect, which can not only retain the oil in the coffee liquid, but also reduce the flow of coffee grounds down through the holes, greatly reduce the fine particles contained in the coffee liquid, and obtain the consistency of the coffee liquid. The right, great-tasting coffee liquid.
