Description

Filter device for brewing beverages

technical field

The utility model relates to a filter device for brewing beverages, in particular to a filter device suitable for hand-brewed coffee or tea leaves, which can avoid the use of filter paper, make the cleaning of the filter cup more rapid and convenient, and be beneficial to human health. filter device.

Background technique

Take pour over coffee or tea leaves as an example. Generally, coffee is brewed by putting coffee powder or tea leaves into a filter cup and then adding boiling water. For the convenience of drinking, hand-brewed coffee or tea is usually used, but to brew a satisfactory cup of coffee or tea, some brewing steps and procedures are necessary, such as using a small-mouth pot that can effectively control the size and stability of the water column At the same time, it is necessary to prevent the water column from breaking and to circle when brewing, and the length of brewing time will affect the drinking quality of coffee or tea. When the brewing time is too short, the taste of coffee or tea is not enough, and the If soaked for too long, it will have a bitter taste.

Fig. 1 shows one of the common hand-brew beverage sets 10 for brewing coffee or tea leaves on the market, which basically includes a beverage container 11 and a beverage filter cup that can be placed on the top spout of the beverage container 11 12. The beverage filter cup 12 is shaped like a hollow funnel, and is provided with a receiving surface 13 for placing on the top surface of the beverage container 11 to form a complete set of hand-brewed tea or coffee beverage set 10 . When the hand-brewed beverage group 10 is hand-brewed coffee or tea leaves, a filter paper 14 can be selected inside the beverage filter cup 12, and the ground coffee powder or bagged tea leaves and coffee 15 can be put into the cup, and then can The boiled water poured from the narrow-mouth pot 16 is brewed through the beverage filter cup 12 and then flows into the beverage container 11 below. However, to brew coffee or tea leaves in this way, filter paper 14 must be used, which is not only wasteful and not environmentally friendly, but this type of filter paper 14 for hand-brewed beverages usually contains chemical components or is made through a bleaching process, which is harmful to the human body. Health can take its toll.

To brew a satisfying cup of coffee drink as an example, basically the freshly roasted coffee beans must be stored in a moisture-proof box for about 20 days, and before brewing, they need to be ground into specific fine-grained coffee powder and heated at a specific temperature The boiled water is brewed for a specific time with the above-mentioned narrow mouth pot 16 at different heights and directions. For the brewing of this type of coffee powder, another filter method is to use another coffee filter cup holder 20 as shown in Figure 2 and Figure 2A to brew coffee or tea. The cup holder 20 is mainly provided with a funnel-shaped filter 23 between an upper cup ring 21 and a lower cup ring 22 , and an outlet 24 is provided at the lower cup ring 22 . In order to form a proper filtration time, as shown in FIG. 2A , the above-mentioned funnel-shaped filter screen 23 is usually a double-layer structure with an inner layer 231 and an outer layer 232 . But this type of double-layer funnel-shaped filter screen 23 will produce grease between the inner layer 231 and the outer layer 232 after repeated use. And the interlayer grease between the outer layer 232 must be cleaned with citric acid or baking soda powder, which will also have adverse effects on human health.

Utility model content

In order to achieve the above purpose, the utility model discloses a filter device for brewing beverages, which includes a beverage brewing group, and the beverage brewing group is provided with a filter cup; the filter cup is provided with at least one top opening and a bottom surface , the bottom surface is provided with at least one water outlet; it is characterized in that:

A filtering device is positioned inside the filter cup in accordance with the shape of the inner surface of the bottom surface, and is located above the water outlet; the filtering device includes a filter screen, an inner positioning frame, and a frame larger than the inner positioning frame The outer positioning frame, the filter screen forms a filter surface, and the skirt portion located on the periphery of the filter surface; the filter screen is sleeved on the inner positioning frame, so that the above-mentioned filter surface is positioned on the inner positioning frame A filter layer is formed above, and the above-mentioned skirt part is covered on the outer surface of the inner positioning frame, and the outer positioning frame is inserted into the combination so that the skirt part is sandwiched and positioned between the inner positioning frame and the outer Position between frame pieces.

Wherein, the inner positioning frame and the outer positioning frame are respectively provided with a plurality of permeable holes.

Thus, the filter screen of the present invention is sleeved on the inner positioning frame, so that the above-mentioned filtering surface forms a filter layer above the inner positioning frame, and the above-mentioned skirt part is covered on the outer surface of the inner positioning frame. , the outer positioning frame is inserted into the combination so that the skirt part is clamped and positioned between the inner positioning frame and the outer positioning frame; thus no need to use filter paper, and the cleaning of the filter screen is more efficient fast and convenient.

In a preferred embodiment, the inner positioning frame and the outer positioning frame are respectively provided with a plurality of permeable holes, so that the brewed beverage passes through the filter surface on the front side of the filter screen and through the skirt part through the permeable holes of the outer positioning frame on the side. After passing through the water permeable hole of the inner positioning frame, the water drips from the water outlet and is collected in the beverage container.

Wherein, the aperture size of the water permeable hole can be selected and set according to the brewing and filtering speed.
