Description

double layer filter bowl

The invention relates to a beverage brewing device, especially a filter device for brewing coffee.

Coffee brewing can be divided into many different brewing methods according to the contact mode of water and ground coffee powder. The traditional drip method is to place coffee powder in a funnel-shaped filter paper, and then slowly pour hot water into the filter paper. , the hot water seeps through the coffee powder through gravity and drips through the filter paper into the container below, while the brewed coffee powder is left in the filter paper and discarded together with the filter paper after the brewing is completed. With the rising awareness of environmental protection, some industry players have developed reusable metal or plastic filters to replace traditional filter papers that can only be used once.

Coffee beans come in many different varieties, and brewing conditions will vary depending on the variety. When some types of coffee beans are brewed, the contact time between hot water and coffee powder needs to be controlled to be short in order to obtain a good flavor. That is to say, some types of coffee need to be brewed with a coarse mesh filter to avoid Make sure that the hot water can pass through the strainer quickly when brewing, so as to obtain a good extraction flavor.

However, when the mesh of the filter screen is relatively thick, a small amount of coffee powder will penetrate the filter screen with hot water, causing coffee grounds to appear in the brewed coffee, which affects the drinking taste of the coffee.

Therefore, the filtering device used for brewing coffee in the prior art really needs to be improved.

In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides a double-layer filter to filter out coffee grounds while maintaining the extracted flavor.

In order to achieve the above-mentioned creative purpose, the technical means adopted in this creation is to design a double-layer filter cup, which is used to set an upper opening of a container and to brew coffee powder. The double-layer filter cup includes: a container A fixing seat, which is used to be arranged on the upper opening of the container; the container fixing seat has at least one drain hole, and each of the at least one drain hole penetrates the container fixing seat up and down; an upper layer filter cup, which is arranged on the container The top surface of the fixing seat; the upper filter cup has an upper filter space, a spout and a plurality of upper fine filter holes; the spout is located on the top of the upper filter cup; the upper filter space is used to accommodate the coffee powder ; Each of the upper layer fine filter holes penetrates from the inner wall surface of the upper layer filter cup to the outer wall surface; the lower layer filter cup is arranged on the bottom surface of the container fixing seat; the lower layer filter cup has a lower layer filter space, an inlet port and a plurality of The lower filter hole; the inlet is located at the top of the lower filter cup; each lower filter hole penetrates from the inner wall surface of the lower filter cup to the outer wall surface; wherein, the width of each lower filter hole is smaller than that of the upper filter cup The width of the fine filter holes of the upper layer, and the width of each of the lower filter holes is smaller than the particle size of the coffee powder; wherein, the positions of the upper filter cup, the at least one discharge hole of the container fixing seat and the lower filter cup are corresponding, The liquid in the upper filter cup can flow into the lower filter cup sequentially through the upper fine filter holes, the at least one discharge hole of the container fixing seat and the inlet of the lower filter cup.
