[0002] A coffee machine is a device used to make coffee. It extracts the flavor and aroma of coffee by heating water and passing it through coffee powder. The extraction cup (also called a coffee pot or coffee cup) is a container in the coffee machine used to receive the extracted coffee liquid. Usually, the coffee powder is placed in the extraction cup, compacted, and water is slowly passed through it to extract high-concentration coffee liquid from the bottom of the extraction cup.

[0003] After the coffee liquid is extracted from the existing extraction cup, the coffee powder needs to be poured out from the extraction cup. After the powder is poured out, coffee powder will remain in the extraction cup, and the inside of the extraction cup needs to be cleaned with clean water or a cleaning tool, which is time-consuming and labor-intensive. Summary of the invention

[0022] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, an extraction cup for a coffee machine comprises a cup body 1, a rotating component 2 is installed in the cup body 1, and an extraction component 3 for extracting coffee liquid is installed in the rotating component 2 so as to be movable in a lifting manner.

[0024] In this embodiment, the extraction component 3 movably installed in the rotating component 2 is used to realize the coffee liquid extraction function. At the same time, the lifting and lowering movement of the extraction component 3 can be used to push the coffee powder and residue out of the cup body 1 of the extraction cup to complete the work of quickly cleaning the residue.

[0025] Furthermore, the rotating component 2 is a hollow structure, and is divided into an external part 4 exposed at the top of the cup body 1 and an internal part 5 installed inside the cup body 1, and the inner wall of the internal part 5 is provided with a thread 6. By screwing the external part 4, the rotating component 2 can be rotated, and the extraction component 3 installed in the internal part 5 of the rotating component 2 will move up and down in the vertical direction as the rotating component 2 rotates.

[0026] Furthermore, the extraction component 3 is a hollow structure, the interior of which is a liquid channel 7, the outer wall of the extraction component 3 is provided with a spiral groove 8 that cooperates with the thread 6, and the lower part of the outer wall of the extraction component 3 is also vertically provided with a plurality of positioning grooves 9. The spiral groove 8 on the outside of the extraction component 3 cooperates with the thread 6 on the inner wall of the built-in part 5, and when the rotating component 2 rotates, the thread 6 rotates accordingly, thereby linking the extraction component 3.

[0027] Furthermore, a filter screen 10 is fixedly arranged at the top opening of the extraction component 3, and a guide plate 11 is provided inside the extraction component 3 near the opening, and the center of the guide plate 11 is connected to the liquid channel 7. The guide plate 11 facilitates the extraction of the coffee liquid into the liquid channel 7.

[0028] Furthermore, a limiting ring 12 is integrally provided on the outer wall of the bottom of the built-in portion 5 .

[0029] Furthermore, the inner wall of the cup body 1 is provided with a limiting groove 13 for engaging with the limiting ring 12, and the lower part of the inner wall of the cup body 1 is also provided with a plurality of fixing bars 14 that slide with the positioning groove 9. The rotating part 2 is stably installed in the cup body 1 through the limiting ring 12, so that the rotating part 2 will not fall off from the cup body 1 when rotating; by providing the fixing bar 14 at the lower part of the inner wall of the cup body 1, and slidingly matching the fixing bar 14 with the vertically arranged positioning groove 9 arranged on the outer wall of the extraction part 3, it can be ensured that the extraction part 3 will not rotate with the rotating part 2 when the rotating part 2 rotates, thereby affecting its function of moving in the vertical direction.

[0030] Furthermore, the rotating part 2 is installed in the cup body 1 through the limiting ring 12, and the extraction part 3 is movably installed in the rotating part 2 through the spiral groove 8. When the rotating part 2 rotates, the extraction part 3 can move in the vertical direction due to the mutual cooperation between the thread 6 provided on the inner wall of the built-in part 5 and the spiral groove 8 on the outer wall of the extraction part 3. By rotating the rotating part 2 in different directions, the moving direction of the extraction part 3 in the vertical direction can be controlled.

[0031] Furthermore, the radius of the extraction component 3 is consistent with the radius of the hollow part of the rotating component 2 and the lower part of the cup body 1. The extraction component 3 is in a state of being in contact with the inner wall of the rotating component 2 and the cup body 1, so that when the extraction component 3 rises to push the powder residue out of the cup body 1, no powder residue will remain on the inner wall of the rotating component 2.

[0032] The working process and principle of the utility model are as follows:

[0033] Under normal conditions, the extraction component 3 is stored in a position near the lower part of the rotating component 2, and the positioning groove 9 on the outside of the extraction component 3 and the fixing strip 14 on the inner wall of the cup body 1 slide with each other. At this time, a certain volume of cavity is reserved in the rotating component 2 for placing coffee powder. After the coffee powder is compacted, hot water is added to extract the coffee liquid, and the coffee liquid flows to the guide plate 11 through the filter 10 provided on the extraction component 3. After being guided by the guide plate 11, the coffee liquid is discharged downward from the liquid channel 7. When the coffee liquid extraction is completed, the coffee powder residue needs to be cleaned. The rotating component 2 is rotated to make the rotating component 2 drive the extraction component 3 to rise, and the compacted powder residue mass is pushed out of the cup body 1. When the filter 10 is flush with the top of the rotating component 2, the powder residue mass can be cleaned. In the process of the extraction component 3 rising, the coffee powder residue on the inner wall of the rotating component 2 is pushed out together, so that quick cleaning can be achieved.

[0034] When the extraction component 3 needs to be cleaned separately, the rotating component 2 can be rotated to make the extraction component 3 rise and expose the top of the rotating component 2, and then the rotating component 2 can be kept stationary, and the extraction component 3 can be manually rotated to make the spiral groove 8 on the outer wall of the extraction component 3 gradually disengage from the thread 6 on the inner wall of the rotating component 2, and the extraction component 3 can be disassembled.

[0035] The above detailed description of the specific implementation of the utility model is only used as an example. The utility model is not limited to the specific implementation described above. The technicians in the industry should understand that the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
