The concave annular surface portion 213 has a plurality of convex ribs 214 that are circumferentially surrounded and spaced apart from each other.
[0037] Refer to
[0038] Refer to Figure 3 、 Figure 4 And Figure 5, the flow guiding unit 3 is disposed on the bottom wall 11 and extends downward. In this embodiment, one end of the flow guiding unit 3 extends into the setting groove 113 and is detachably disposed at the joint portion 114 of the bottom wall 11. In this embodiment, the flow guiding unit 3 is used to guide water flow and includes a plurality of pipe bodies 31 that can be disassembled and assembled with each other. The pipe bodies 31 define a flow guiding space 30 that communicates the discharge port 115 with the outside. The suction gap 20, the gap 200, the concave hole 210, the suction port 131, the discharge port 115, and the flow guiding space 30 cooperate to define a flow path F for fluid flow.
[0039] Each of the pipe bodies 31 has a first end portion 312 formed with a first internal thread 311, a second end portion 314 opposite to the first end portion 312 and formed with a second external thread 313, and an extension portion 315 defined between the first end portion 312 and the second end portion 314. The first end portion 312 of one of the pipe bodies 31 of the flow guiding unit 3 is used to detachably engage with the joint portion 114 of the bottom wall 11, and the first end portions 312 of the other pipe bodies 31 are used to be screwed to the second end portions 314 of the adjacent pipe bodies 31. In this embodiment, one of the pipe bodies 31 is screwed to the first external thread 116 of the joint portion 114 through the first internal thread 311, and the other pipe bodies 31 are screwed to the second external threads 313 of the adjacent pipe bodies 31 through the first internal thread 311.
[0040] BCPI - 240334 Page 5 / 6
[0041] It should be noted that, in this embodiment, the number of the pipe bodies 31 is three, but it can also be one, two, or more than four, as long as the function that the pipe bodies 31 can be disassembled and assembled with each other can be achieved. The present invention is not limited thereto.
[0042] The pipe bodies 31 of this embodiment are connected to the joint portion 114 of the bottom wall 11 by screwing, and the structural stability is high. However, in other variations, the pipe bodies 31 can also be fixed to the joint portion 114 by other connection methods such as snap connection or fitting, and the present invention is not limited thereto.
[0043] When making brewed coffee, first, place this embodiment on the top of a container (not shown in the figure), and then fold a filter paper (not shown in the figure) along the conical surface 22 of the bump unit 2 and place it in the cup unit 1. Next, pour coffee powder (not shown in the figure) into the brewing space 10, and pour hot water along the inner peripheral surface 121 of the surrounding wall 12 and the conical surface 22 of the bump unit 2. The hot water flushes into the coffee powder and flows downward into the suction gap 20, and finally flows into the container along the flow channel F from the discharge port 115 and the diversion space 30, so as to obtain a uniformly extracted brewing liquid. In some applications, the utility model can also be used to make tea.
[0044] According to the principle that there is an attraction between liquid molecules, when water flows from the discharge port 115 into the diversion space 30, the diversion space 30 can guide the water flow and accelerate the discharge of the water flow. Therefore, this embodiment can effectively improve the flow rate of the water flow.
[0045] At the same time, this embodiment forms the suction gap 20 between the cup unit 1 and the bump unit 2, and uses the structural design that the suction port 131 is higher than the suction gap 20. Through the pressure difference caused by the height difference of the water level and the siphon principle of the attraction between liquid molecules, the liquid can be pushed to cross the highest suction port 131 and be discharged to the lower discharge port 115, so as to increase the outflow speed of the brewing liquid.
[0046] Through the above description, the advantages of the foregoing embodiments can be summarized as follows:
[0047] 1. Since there is an attraction between liquid molecules (such as water molecules), when water flows from the discharge port 115 into the diversion space 30, the diversion space 30 can guide the water flow and accelerate the discharge of the water flow. Therefore, the utility model can indeed achieve the effect of improving the flow rate of the water flow.
[0048] 2. Compared with the direct outflow of water from the discharge port 115, the diversion unit 3 of this embodiment can restrict the water flow direction and further prevent the splashing of the liquid.
[0049] 3. Since the coffee powder or tea leaves can be dispersed between the cup unit 1 and the bump unit 2, it can avoid the accumulation of coffee powder or tea leaves at the bottom of the cup unit 1, and use the structural design that the suction port 131 is higher than the suction gap 20. Through the pressure difference caused by the height difference of the water level BCPI - 240334 Page 6 / 6
[0050] and the siphon principle between liquid molecules, the outflow speed of the brewing liquid is increased, thereby improving the extraction uniformity.
[0051] The above are only the embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present utility model still fall within the scope of the present utility model.
