[0002] .Coffee, as a beverage, has become very popular. For fresh coffee, coffee beans are usually ground into coffee powder first, and then the coffee powder is filtered and extracted with filter paper to obtain coffee liquid. Currently, only conical filter paper is placed on the filter cup, and then the coffee powder is poured onto the filter paper and rinsed with warm water. Since the bottom of the filter paper is conical, the thickness of the coffee powder layer tends to increase and become clogged easily. At the same time, the contact surface between the coffee powder and the filter paper is only the fan-shaped surface of the filter paper, with a small contact area. The water takes a long time to pass through, resulting in a low extraction rate and a long extraction time, which greatly affects the taste of the coffee. Summary of the invention

[0005] Furthermore, two adjacent bumps have different thicknesses.

[0006] Furthermore, the bumps include bumps of two thicknesses, and the bumps of the two thicknesses are staggered.

[0007] Furthermore, the inner bottom plate protrudes upward, and the upper end surface of the inner bottom plate is higher than the upper end surface of the support frame.

[0008] Preferably, the side wall of the annular groove extends downward to form an extension ring, one end of the support frame is connected to the extension ring, and the lower end surface of the inner bottom plate is higher than the upper end surface of the support frame.

[0018] The utility model is described in detail below with reference to the accompanying drawings. Figures 1 to 3 shown.

[0019] Example 1: See Figure 1 , Figure 2 A coffee filter cup, comprising: a cup bottom 1, an annular groove 5 is provided in the middle of the cup bottom 1, an inner bottom plate 6 is formed inside the annular groove 5, at least three support frames 4 are connected between the inner bottom plate 6 and the cup bottom 1, the inner side wall of the annular groove 5 extends upward to form an inverted cone-shaped cup body 2, and the inner side surface of the cup body 2 is provided with a plurality of inwardly protruding bumps 3, and the side surfaces of the bumps 3 are arranged in an arc shape.

[0020] When the present technical solution is used, the coffee filter cup is placed above the extraction cup, the cup bottom 1 is overlapped on the extraction cup, the inner bottom plate 6 is located above the opening of the extraction cup, and the filter paper is surrounded in a cone shape; the lower end of the filter paper abuts against the support frame 4 and the side of the lower end of the filter paper abuts against the side wall of the inner bottom plate 6, and the upper end of the filter paper fits or is close to the side of the cup body 2; because the inner side of the cup body 2 is provided with a plurality of protrusions 3, the inner side area of ​​the cup body 2 is increased, and the contact area between the filter paper and the cup body 2 is increased; secondly, due to the setting of the protrusions 3, when the inner side of the cup body 2 abuts against the filter paper, the filter paper is wavy, and the filter paper is subjected to different abutment forces of the inner side in different areas, and there are more or less gaps between the filter paper and the side wall of the cup body 2; so that the filter paper has a certain air permeability while fitting the side wall, and the obstruction of the coffee liquid circulation is relatively small. The extraction time of the coffee liquid is optimized, which is conducive to improving the taste of the coffee extract.

[0021] Furthermore, two adjacent bumps 3 have different thicknesses.

[0022] The thickness of the protrusions of two adjacent protrusions 3 is set to be different. When the filter paper is attached to the cup body 2, the undulation height of the filter paper is different, resulting in a change in the curvature of the bending of the filter paper. Since the filter paper has a certain thickness, the bending shrinkage degrees of the front and back sides of the filter paper are different after the filter paper is bent, and the filter paper cannot completely fit tightly against the side wall of the cup body 2; further expanding the gap between the filter paper and the side wall of the cup body 2.

[0023] It should be noted that the thickness of the protrusion 3 is a relative thickness. In a certain cross section of the cup body 2, the distance between the farthest point of the protrusion 3 and the side edge of the cup body 2 is the thickness of the protrusion 3. The protrusion 3 is also set in a cone shape. The comparison of thickness is the comparison on the same horizontal cross section, which is parallel to the bottom surface of the cup bottom 1.

[0024] Furthermore, the bumps 3 include bumps 3 of two thicknesses, and the bumps 3 of the two thicknesses are staggered.

[0025] By setting two thicknesses of the protrusions 3 and setting them in the wrong way, so that the positions of the protrusions 3 are set high and low, the filter paper can fit the wall of the cup and have air permeability, and the flow of coffee liquid is not blocked, which greatly improves the brewing efficiency and the flavor of the coffee liquid extraction.

[0026] Furthermore, the inner bottom plate 6 protrudes upward, and the upper end surface of the inner bottom plate 6 is higher than the upper end surface of the support frame 4 .

[0027] The inner bottom plate 6 is raised upward to form a height difference between the inner bottom plate 6 and the support frame 4, and a gap is formed between the inner bottom plate 6 and the side wall of the cup body 2, and the lower end of the filter paper can be inserted into the gap; the contact area between the lower end of the filter paper and the inner bottom plate 6 is larger and more fitted.

[0028] Preferably, the side wall of the annular groove 5 extends downward to form an extension ring 7 , one end of the support frame 4 is connected to the extension ring 7 , and the lower end surface of the inner bottom plate 6 is higher than the upper end surface of the support frame 4 .

[0029] The support frame 4 is designed to be positioned relatively low, so that the thickness of the inner bottom plate 6 can be increased, and the contact surface between the filter paper and the inner bottom plate 6 can be further increased; at the same time, it is beneficial to the circulation of the coffee liquid. At the same time, preferably, the width of the gap is equivalent to the thickness of the filter paper, which is beneficial to fix the lower end of the filter paper.

[0030] Furthermore, the middle portion of the inner bottom plate 6 is convex upward.

[0031] The middle part of the inner bottom plate 6 is raised so that coffee liquid will not be deposited on the inner bottom plate 6 .

[0032] Furthermore, four support frames 4 are connected between the inner bottom plate 6 and the cup bottom 1 .

[0033] In order to increase the bearing points at the lower end of the filter paper, the technical solution provides four support frames 4 .

[0034] Furthermore, the periphery of the cup bottom 1 extends downward to form a limiting ring 8 .

[0035] After the limiting ring 8 is formed, when combined with the extraction cup, the limiting ring 8 is sleeved on the outside of the extraction cup to prevent the cup bottom 1 from moving relative to the extraction cup or detaching from the extraction cup.

[0036] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
