[0027] Further, the lower end of base 1 is fixedly connected with an anti-skid layer.

[0028] Press assembly 3 includes sealing plug 31 movably connected on the upper side of the inner surface of brewing cup 2, lower pressing part 32 fixedly connected in the middle of sealing plug 31, and rotating part 33 rotatably connected in the middle of lower pressing part 32.

[0029] As Figure 3 And Figure 4 Indicated, lower pressing part 32 includes shell 321 fixedly connected in the middle of sealing plug 31, rotating grooves 322 are formed on the upper side and the lower side of the inner surface of shell 321, and pressing plate 323 is fixedly connected to the upper end of shell 321.

[0030] As Figure 3As shown, the rotating part 33 includes a rotating rod 331 rotatably connected to the inner surface of the housing 321. Limiting rings 332 are fixedly connected to the upper and lower sides of the outer surface of the rotating rod 331, and a handle 333 is fixedly connected to the upper end of the rotating rod 331.

[0031] Specifically, both limiting rings 332 are rotatably connected in a rotating groove 322 that is close to each other.

[0032] Furthermore, a spring 34 is fixedly connected to the upper end of the sealing plug 31 and the lower end of the pressure plate 323, and the spring 34 is sleeved on the upper side of the outer surface of the housing 321.

[0033] In this embodiment, the pressing component 3 is removed from the brewing cup 2, and an appropriate amount of ground coffee powder and hot water are poured into the brewing cup 2. The pressing component 3 and the stirring component 4 are then placed back into the brewing cup 2. The sealing plug 31 fixes the pressing component 3 to the brewing cup 2. Then, the pressure plate 323 is pressed downwards, and the pressure plate 323 moves the housing 321 downwards. The housing 321 pushes the support 5 and the filter screen 6 downwards to separate the coffee grounds and coffee liquid. After separation, the coffee liquid can be poured out of the brewing cup 2. Finally, the pressing component 3 can be removed to clean the coffee grounds in the brewing cup 2.

[0034] Example 2

[0035] Based on Example 1, this embodiment adds a stirring component 4, which can stir the coffee powder and water before pressing and filtering, so that the coffee powder can be fully extracted and the taste of the coffee can be improved.

[0036] like Figure 5 As shown, the stirring assembly 4 includes a threaded rod 41 connected to the lower side of the inner surface of the housing 321.

[0039] Different filter screen materials and aperture will affect the extraction effect and taste of coffee, for example, metal filter screen can retain more coffee oil and fine powder, making coffee taste more complex and rich; while filter paper can filter out most of the oil and particles, making coffee clearer, so you can choose the appropriate filter screen to get the best coffee brewing taste.

[0040] Meanwhile, during use, the filter screen 6 will be worn out, and regular replacement of the filter screen 6 can ensure the filter pressing effect of the device.

[0041] The working principle of the utility model is as follows: firstly, the pressing assembly 3 and the stirring assembly 4 are taken out from the brewing cup 2, and then a proper amount of ground coffee powder and hot water are poured into the brewing cup 2 in sequence, the pressing assembly 3 and the stirring assembly 4 are put into the brewing cup 2 again, the sealing plug 31 fixes the pressing assembly 3 and the brewing cup 2, then the handle 333 is rotated, the handle 333 drives the stirring assembly 4 to rotate, the connecting rod one 44 stirs the coffee powder and water, so that the coffee powder is fully extracted, then the pressing plate 323 is pressed downward, the pressing plate 323 drives the shell 321 to move downward, the shell 321 pushes the support 5 and the filter screen 6 to move downward, so as to separate the coffee residue and the coffee liquid, after the separation is completed, the coffee liquid can be poured out from the brewing cup 2, finally, the pressing assembly 3 and the stirring assembly 4 can be taken out, and the coffee residue in the brewing cup 2 is cleaned;

[0042] When it is necessary to replace the filter screen 6, the threaded rod 41 can be rotated, the threaded rod 41 is taken out from the shell 321, a new filter screen 6 is replaced, and then the threaded rod 41 is fixed with the shell 321.

[0043] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, the above examples and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
