[0015] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0016] Embodiment: As shown in the attached Figure 1 , the present utility model relates to a structure of a portable coffee brewing utensil, including a cup body 1, a filter cup 2, and an upper cover 3 arranged in sequence from bottom to top. Both the upper and lower ends of the filter cup 2 are open. The bottom end of the filter cup 2 is threadedly connected to the cup body 1, and the top end is threadedly connected to the upper cover 3. The outer diameter of the filter cup 2 gradually increases from top to bottom, and the outer shape of the filter cup 2 can be frustum-shaped. A conical space for placing the filter paper 4 is provided inside the filter cup 2. The outer diameter of the top of the filter cup 2 is smaller than the inner diameter of the open top of the cup body 1, and the outer diameter of the bottom is larger than the inner diameter of the open top of the cup body 1. After connecting the cup body 1, the filter cup 2, and the upper cover 3 in sequence from top to bottom, a coffee cup container is formed. After removing the upper cover 3 from the filter cup 2 and then removing the filter cup 2 from the cup body 1, the top end of the filter cup 2 can be inserted into the cup body 1 with the top end facing down.

[0017] Preferably, in order to ensure the sealing performance of the connection between the cup body and the filter cup, the top of the cup body 1 is provided with a first external thread, the bottom of the filter cup 2 is provided with a first internal thread adapted to the first external thread, and a first sealing ring 5 is provided above the first internal thread.

[0018] Preferably, in order to ensure the sealing performance of the connection between the upper cover and the filter cup, a second external thread is provided at the top of the filter cup 2, a second internal thread adapted to the second external thread is provided on the upper cover 3, and a second sealing ring 6 is provided on the upper side of the second internal thread.

[0019] Preferably, a plurality of external support feet 7 are evenly arranged along the circumferential direction of the outer wall of the filter cup 2 in the middle of the outer wall of the filter cup 2. The distance between the outer end of the external support foot 7 and the axis of the filter cup 2 gradually increases from top to bottom. The maximum distance value between the outer end of the external support foot 7 and the axis of the filter cup 2 is greater than the inner diameter of the top opening of the cup body 1, and the minimum distance value between the outer end of the external support foot 7 and the axis of the filter cup 2 is less than the inner diameter of the top opening of the cup body 1. When the top end of the filter cup 2 is inserted downward into the cup body 1, the external support foot 7 abuts against the inner wall of the top opening of the cup body 1, so that an air circulation gap is left between the top opening of the cup body 1 and the filter cup 2, which is convenient for the brewing of coffee powder.

[0020] Preferably, a plurality of internal support feet are evenly arranged along the circumferential direction of the inner wall of the conical space on the inner wall of the conical space. The distance between the internal support foot and the axis of the filter cup 2 gradually increases from top to bottom. After the top end of the filter cup 2 is inserted downward into the cup body 1, the filter paper 4 is placed in the conical space, and the internal support foot provides support for the filter paper 4, so that an air circulation gap is left between the filter paper and the inner wall of the conical space, which is convenient for the brewing of coffee powder.

[0021] When the utility model is in use, first unscrew the upper cover 3, then unscrew the filter cup 2, then turn the filter cup 2 by 180°, insert the top end of the filter cup 2 into the cup body 1, first put the cake-shaped filter paper 4 and the ground coffee powder into the conical space of the filter cup 2, start brewing coffee. After the coffee brewing is completed, remove the filter cup 2, pour out the filter paper 4 and coffee residues, reinstall the filter cup 2 on the cup body 1 through thread fit, and drink the coffee through the top opening of the filter cup. When the external support foot 7 is arranged on the outside of the filter cup 1, the external support foot 7 supports on the top edge of the cup body 1.
