Description

Filter cup

Technical Field

The present utility model relates to a filter for a coffee or tea maker, and in particular to a filter bowl.

Background

When the filtered coffee is brewed by hand, the flavor of the extracted coffee is affected by the factors of coffee powder, the temperature of the hot water to be brewed, the flow rate of the hot water, and the like.

Referring to fig. 1, a coffee filter cup 1 disclosed in taiwan patent publication No. TWM622010U includes a cup body 11 having a conical inner surface 111, and a cup holder 12 fixed to a bottom side of the cup body 11. When brewing coffee, a filter paper 13 is placed in the cup 11, and then coffee powder is placed in the cup and the coffee powder in the cup 11 is showered with hot water along the conical inner surface 111 of the cup, so that the hot water naturally flows downwards by gravity. Since the coffee powder is accumulated at the bottom of the cup 11, the coffee powder at the bottom of the center of the cup 11 is not easily washed by hot water, so that the extraction is not easily uniform, and the flavor and taste of the extracted coffee are to be improved.

Detailed Description

Referring to fig. 2 to 4, an embodiment of the filter bowl of the present utility model includes a bowl unit 2 and a bump unit 3.

The cup unit 2 includes a bottom wall 21, a surrounding wall 22 extending upward and outward from the bottom wall 21 in a height direction L, and a convex portion 23 extending upward from the center of the bottom wall 21.

The bottom wall 21 has a discharge opening 211. The convex portion 23 has a suction port 231 which is higher than the discharge port 211 and is spatially communicated with the discharge port 211. The discharge port 211 of the present embodiment is aligned with the suction port 231.

Referring to fig. 3-5, the surrounding wall 22 is frusto-conical and has an oppositely disposed outer surface 221 and an inner surface 222. The inner surface 222 has a plurality of first guide grooves 223 arranged at intervals and staggered with each other along the circumferential direction angle, and a plurality of second guide grooves 224 arranged between the first guide grooves 223 at intervals and staggered with each other along the circumferential direction angle. Each first flow guiding groove 223 is opened at the top edge of the surrounding wall 22, and the length of each first flow guiding groove 223 is greater than the length of each second flow guiding groove 224.

Referring to fig. 2 to 4, the bump unit 3 is detachably disposed in the cup unit 2, and cooperates with the cup unit 2 to define a brewing space 20 having a ring shape. The bump unit 3 includes a bump body 31 sleeved on the protruding portion 23, and a plurality of supporting portions 32 disposed on the bump body 31 and abutting against the bottom wall 21.

The bump body 31 is a cone, and has a bottom surface 311 facing the bottom wall 21, and a tapered surface 312 tapering upward from the bottom surface 311.

The bottom surface 311 is formed with a concave hole 313 sleeved on the convex portion 23, and a circular gap 310 is formed between the concave hole 313 and the convex portion 23 and is in fluid communication with the suction inlet 231.

Referring to fig. 3 to 5, the tapered surface 312 is formed with a plurality of inner flow guide grooves 314 angularly offset from each other in the circumferential direction, and the groove width of each inner flow guide groove 314 is tapered from bottom to top. In this embodiment, the angle of the tapered surface 312 is between 50 ° and 70 °, and the angle of the tapered surface 312 is between 60 ° and 62 °.

Referring to fig. 4 to 6, the supporting portions 32 are disposed on the bottom surface 311 of the bump body 31, it should be noted that each supporting portion 32 is substantially a bump, and the supporting portions 32 raise the bump body 31 and form a suction gap 30 between the cup unit 2 and the bump body 31, which is lower than the suction opening 231. The suction gap 30, the gap 310, the concave hole 313, the suction port 231, and the discharge port 211 cooperatively define a fluid flow path F through which fluid flows.

When brewing coffee, the present embodiment is first placed on top of a container (not shown), and then a filter paper (not shown) is concavely folded along the tapered surface 312 of the bump unit 3 and placed in the cup unit 2. Next, coffee powder (not shown) is poured into the brewing space 20 and hot water is poured along the inner surface 222 of the surrounding wall 22 and the conical surface 312 of the bump body 31. The hot water is poured into the coffee powder, flows downwards into the suction gap 30 through the first diversion trench 223, the second diversion trench 224 and the inner diversion trench 314, and finally flows into the container from the discharge port 211 along the flow path F, so as to obtain the infusion liquid with uniform extraction.

The suction gap 30 is formed between the cup unit 2 and the bump unit 3, and the suction inlet 231 is higher than the suction gap 30, and the liquid can be pushed to pass over the suction inlet 231 at the highest point and be discharged to the discharge outlet 211 at the low point by utilizing the siphon principle of the pressure difference caused by the height of the water level and the attractive force between liquid molecules, so that the outflow speed of the brewing liquid can be increased.

It should be noted that, when the hot water is showered, the user can selectively flow the hot water through one of the first diversion trench 223, the second diversion trench 224, or the inner diversion trench 314 according to the baking degree of the coffee powder, so as to properly adjust the flow rate of the hot water, thereby making the extracted flavor better. In some applications, the present utility model can also be used to brew tea leaves.

From the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. since the coffee powder or tea can be dispersed between the cup unit 2 and the bump unit 3, the coffee powder or tea can be prevented from being accumulated at the bottom of the cup unit 2, and the suction inlet 231 is higher than the suction gap 30 by the structural design, and the outflow speed of the brewing liquid is improved by the siphon principle of the pressure difference caused by the height of the water level and the attraction between liquid molecules, thereby improving the uniformity of extraction.

2. The user can selectively flow the hot water through the first guide groove 223, the second guide groove 224, or one part of the inner guide groove 314 according to the baking degree of the coffee powder, so that the coffee powder with different baking degrees can have the best taste by properly adjusting the flow rate of the hot water.

The foregoing is merely illustrative of the present utility model and is not intended to limit the scope of the utility model, which is defined by the appended claims and their equivalents.
