Description

Double filter bowl

The present invention relates to a coffee filter device, in particular to a double-filtered filter cup having a better extraction concentration and a filtration diversion effect.

According to the conventional method of manual foaming and brewing coffee, the filter cup with a plurality of perforations on the bottom is placed on the cup, and the filter paper folded into a funnel is placed in the filter cup, and then The appropriate amount of coffee powder is placed in the filter paper, and then the hot water of the predetermined temperature is slowly poured onto the coffee powder, and the coffee liquid is extracted, and the coffee liquid is gradually dripped into the cup by the perforation of the filter paper and the filter bowl. It is available for drinking. The filter paper used in the extraction of coffee is mainly used to block coffee grounds, and can absorb the grease in coffee, which is very convenient to use. However, since filter paper is made of ordinary paper, it is made of plants such as trees. It is less environmentally friendly. Even if it is recycled from recycled paper, it still increases the cost of recycling. It is obviously still improved.

In view of the above situation, the creator invested a lot of time to study relevant knowledge, and compared various advantages and disadvantages, research and development of related products, and after many experiments and tests, finally launched a structure of double-layer filter filter cup. Improve the above-mentioned missing to meet the needs of the public.

The main purpose of this creation is to provide a special arrangement and aperture difference of two kinds of filter holes inside and outside, to improve the filtration speed, and to effectively keep the impurities of the coffee liquid in the filter cup, to avoid clogging the filter hole and increasing the filtering effect.

Another object of the present invention is to provide a structure that can enlarge or reduce the outer diameter of the filter tank. When the outer diameter of the filter tank is enlarged, the cup can be brewed across the cup body, and when the outer diameter of the filter tank is reduced, it can be easily stored in the cup. The internal design of the body provides convenient brewing and storage.

In order to achieve the above object, a double-filtered filter bowl is provided, comprising: a first filter outer layer, which has a tapered outer ring which is hollow at both ends and has a large upper and lower sides, and the ring wall is formed with a majority from top to bottom. The first filter inner layer is a woven mesh, which is correspondingly attached to the inner ring surface of the first filter outer layer, and the mesh of the woven mesh is smaller than the long outer perforation of the first filter outer layer; The two ends are vented, and the inside of the receiving groove is provided with a receiving groove, and the lower end of the receiving groove is downwardly contracted with a conical connecting portion which can be attached to the inner side of the upper opening of the first filtering inner layer, so that the upper end of the first filtering inner layer The part is sandwiched between the connecting portion and the upper end of the first filtering outer layer; a base is a circular cup shape, and has a groove inside, and the groove is provided with a connecting portion which can be attached to the inner annular surface of the lower end of the first filtering inner layer, The lower end of the first filter inner layer is partially sandwiched between the connecting portion and the lower end of the first filter outer layer, and a second filter outer layer having a plurality of circular perforations is formed on the bottom surface of the groove of the base; a second filter inner layer is a woven mesh , which is attached to the top surface of the second filter outer layer in the base. The mesh of the mesh has a smaller diameter than the circular perforation of the second filter outer layer; and a fixing ring piece is attached to the top surface of the second filter inner layer in a ring shape; thus, the double hole of the filter cup and the bottom have a difference in aperture The structure of the layer filtration achieves the effect of better coffee filtration.

A further technical feature of the present invention is that the flow guiding hole on the first filter outer ring wall is one of an inclined shape, a straight shape, a circular arc shape, a curved arc shape, a wave shape, an S shape, and a zigzag shape.

The technical feature of the present invention is that the filter tank is covered with a plastic sleeve along the outer surface, the plastic sleeve has a thread at the lower end, the threaded screw is provided with a loop, and the upper end of the loop has a plurality of claws, and the loop rotates upward. The paw can be extended to an outer diameter larger than the outer diameter of the upper end of the plastic sleeve, and the downward rotation can retract the paw to its original size.

A further technical feature of the present invention is that the inner side wall of the filter tank is provided with a plurality of fixing convex portions.

Based on the above technical features described in this creation, the main advantages of this creation are: (1) the special arrangement of the diversion holes and the aperture difference between the inner and outer layers of the filter cup and the bottom and the outer layer, resulting in tension With the guiding effect, the filtration speed is increased, and the impurities of the coffee liquid are effectively retained in the filter bowl, thereby avoiding clogging of the filter hole and increasing the filtering effect, thereby achieving the best extraction and dripping coffee effect. (2) The filter tank of the creation filter cup can enlarge the outer diameter to be stacked on the upper end of the cup for brewing, or the outer diameter can be reduced and stored in the inside of the cup body to provide convenient brewing and storage. Therefore, this creation can be said to be a kind of practical and progressive creation, which is worthy of promotion by the industry and publicized to the public.
