[0028] For ease of use, a cup 6 is sleeved on the lower end of the body 1. A cavity 61 with an upper opening is provided in the cup 6. The upper opening of the cavity 61 is non-circular, and the non-circular opening can be a polygon. In this embodiment, it is a quadrilateral. Of course, the corners of the quadrilateral have chamfers and are not a pure quadrilateral. A non-circular supporting end 18 is provided on the lower end of the body 1 to match the opening of the cavity 61. The supporting end 18 is slightly smaller than the cavity 61, so that the supporting end 18 can be inserted into the cup 6. The shape of the non-circular supporting end 18 matches the opening of the cavity 61. The connecting groove 12 is provided in the non-circular supporting end 18. A supporting notch 19 is provided on the supporting end 18. The supporting notch 19 is provided at the corner. There are four supporting notches 19. When the cup 6 is pulled out of the sleeved state of the body 1 and rotated a certain angle relative to the body 1, the supporting notch 19 presses against the edge of the opening of the cavity 61 so that the cup 6 supports the body 1. Due to the non-circular shape, after the cup 6 is rotated, the corners of the cup 6 and the corners of the supporting end 18 are misaligned, thereby achieving support. Taking this embodiment as an example, the cup 6 and the support end 18 are both quadrilaterals. After the cup 6 is rotated 45 degrees (such as Figure 5 As shown in the figure, the corners of the cup 6 and the support end 18 are misaligned, so that the two cannot be directly inserted. Therefore, the support end 18 can be pressed against the opening of the cup 6, and the cup 6 supports the entire coffee machine. In this state, the head 3 is separated from the bottom of the cup 6 by a certain distance, which facilitates the flow of coffee into the cup 6. In this way, when brewing, the coffee can automatically flow into the cup 6, and there is no need to manually hold the coffee machine, which is convenient to use.
