[0069] For the purposes, technical solutions and advantages of the embodiments of the present utility model to be clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0070] Embodiment 1

[0071] This embodiment provides a coffee extraction cup, as Figure 1 and Figure 2 shown, which includes an outer cup 1 and a pressure filtration assembly that can slide along the inner wall of the outer cup 1. The pressure filtration assembly includes a pressing part and a filtering part provided below the pressing part. The filtering part and the outer cup 1 enclose a pressure filtration space for the solvent to leach the solid raw material to make a leaching solution;

[0072] In this embodiment, the solvent includes but is not limited to water and milk, and the solid raw material can be coffee powder;

[0073] The filtering part includes a support body, a filter sheet 3, and a coarse filtering part 4 that are sequentially arranged from the cup mouth to the cup bottom of the outer cup 1. The support body and the coarse filtering part 4 are both provided with mesh holes. The mesh number of the support body allows the leaching solution to pass through. The mesh number of the filter sheet 3 is greater than that of the coarse filtering part 4. The support body is arranged on the pressing part, and the filter sheet 3 is arranged in the accommodation space surrounded by the support body and the coarse filtering part 4;

[0074] Pour coffee powder and solvent into the outer cup 1, mix and brew them in proportion according to personal taste to obtain a leaching solution with coffee powder, and then insert the pressure filtration assembly into the outer cup 1. Press down the pressing part to drive the pressure filtration assembly to descend along the inner wall of the outer cup 1, forcing the leaching solution to rise above the filtering part through the filtering part from the pressure filtration space.

[0075] For the coffee extraction cup provided in this embodiment, by pressing down the pressing part, the filtering part descends. After the coarse filtering part 4 of the filtering part preliminarily filters the leaching solution, it is secondarily filtered through the filter sheet 3 with a larger mesh number to effectively remove coffee powder. The mesh holes provided on the support body enable the leaching solution that has been secondarily filtered to pass through the support body. The user directly drinks the secondarily filtered leaching solution through the outer cup 1, improving the user's drinking experience; at the same time, the filtration of coffee powder is divided into primary filtration and secondary filtration, which not only improves the filtration efficiency but also disperses the downward pressure resistance, making it easier for the user to perform the downward pressing operation.

[0076] In a specific embodiment, as Figure 1 and Figure 2 shown, both ends of the outer cup 1 are open, and the bottom of the outer cup 1 is provided with a detachable end cap 10;

[0077] Since coffee powder will deposit at the bottom of the outer cup 1 and is inconvenient to clean, a threaded end cap 10 is provided at the bottom of the outer cup 1 for easy disassembly and cleaning (a food-grade silicone sealing ring can be provided on the end cap 10 according to actual needs to prevent leakage).

[0078] In a specific embodiment, the filter sheet 3 is selected from a metal filter screen, filter paper, filter cotton, or non-woven fabric. The metal filter screen is preferably a stainless steel filter screen. The filter sheet 3 can be adjusted according to actual needs. The filter paper and filter cotton have a larger mesh number and better filtering effect. Correspondingly, the resistance during pressing is greater and the operation is more laborious. In order to reduce the resistance during pressing, a metal filter screen or non-woven fabric with a smaller mesh number can be used as the filter sheet 3.

[0079] In a specific embodiment, as Figure 1 and Figure 2 shown, the pressing part is an inner cup 9. Both ends of the inner cup 9 are through. The inner cup 9 can slide along the inner wall of the outer cup 1, and a pressing part sealing ring 16 is provided between the inner cup 9 and the outer cup 1;

[0080] In this embodiment, as Figure 5As shown, a pressing piece sealing ring 16 is fixed on the outer periphery of the inner cup 9. The pressing piece sealing ring 16 can ensure that when the inner cup 9 is pressed down, the leachate does not escape from the gap between the inner cup 9 and the outer cup 1, and at the same time ensure that the pressure does not leak from the gap between the inner cup 9 and the outer cup 1, so that the leachate can smoothly pass through the filter part from the filter press space and rise to above the filter part.

[0081] In a specific embodiment, Figure 1 and Figure 2 As shown, the support body is a filter disc 11, as shown Figure 3 and Figure 4 As shown, the filter disc 11 includes a disc body 1101. After the coarse filter part 4 is inserted into the disc body 1101, the outer periphery of the coarse filter part 4 can be engaged with the inner wall of the disc body 1101. The disc body 1101 is provided with an outer edge 1102, and the bottom of the disc body 1101 is provided with mesh holes.

[0082] After the filter disc 11 is inserted into the inner cup 9, the outer edge 1102 abuts against the bottom of the inner cup 9. In this embodiment, a support body sealing ring 17 is provided on the outer periphery of the filter disc 11 to prevent the filter disc 11 from falling off the inner cup 9, and the leachate does not escape from the gap between the inner cup 9 and the filter disc 11. At the same time, it ensures that the pressure does not leak from the gap between the inner cup 9 and the filter disc 11, so that the leachate can smoothly pass through the filter part from the filter pressure space and rise to above the filter part.

[0083] In a specific embodiment, Figure 7 and Figure 8 As shown, the coarse filter portion 4 is provided with an isolation protrusion 5 on one side close to the filter disc 3, and a handle 6 is provided on the other side of the coarse filter portion 4. The isolation protrusion 5 is used to prevent the filter disc 3 from being completely attached to the coarse filter portion 4, so as to prevent the filter disc 3 and the coarse filter portion 4 from being adhered to each other by the coffee powder soaked after filtration and unable to be separated. By providing the handle 6, it is convenient for the user to pull the coarse filter portion 4 out of the support body;

[0084] In this embodiment, if Figure 6 As shown, the handle 6 and the isolating protrusion 5 are made of food-grade silicone, and the handle 6 and the isolating protrusion 5 are integrally formed, and a slot 18 is provided between the two. The coarse filter part 4 is a stainless steel filter mesh fixed with reinforcing ribs 19, and a sealing ring can be sleeved on the outer periphery of the coarse filter part 4 to prevent it from falling off the supporting body. A through hole is opened in the middle of the coarse filter part 4, and the handle 6 passes through the through hole from one side of the coarse filter part 4 and exits from the other side, so that the handle 6 and the isolating protrusion 5 are connected to the coarse filter part 4 through the slot 18.

[0085] Example 2

[0086] This embodiment provides a coffee extraction cup, such as Figure 9 and Figure 10As shown, the main structure of this embodiment is similar to that of Embodiment 1. The difference between this embodiment and Embodiment 1 lies in the following point:

[0087] In Embodiment 1, as Figure 1 shown, the support body is the filter disc 11. The disc body 1101 of the filter disc 11 only needs to ensure that it can accommodate the filter sheet 3 and the coarse filter part 4, and the depth is relatively shallow.

[0088] In this embodiment, the support body is a commercially available coffee powder bowl 14. The coffee powder bowl 14 can accommodate a coffee powder cake and has a greater depth than the filter disc 11. After the coarse filter part 4 is inserted into the coffee powder bowl 14, the outer periphery of the coarse filter part 4 can be snap-fitted with the inner wall of the coffee powder bowl 14;

[0089] After the coffee powder bowl 14 is inserted into the inner cup 9, the rim of the coffee powder bowl 14 abuts against the bottom of the inner cup 9. In this embodiment, a support body sealing ring 17 is sleeved on the outer periphery of the coffee powder bowl 14, which can prevent the coffee powder bowl 14 from falling off the inner cup 9, prevent the leaching liquid from running out from the gap between the inner cup 9 and the coffee powder bowl 14, and at the same time ensure that the pressure does not leak from the gap between the inner cup 9 and the coffee powder bowl 14, so that the leaching liquid can smoothly pass through the filter part from the pressure filtration space and rise above the filter part.

[0090] When making Italian espresso extracted using a coffee powder cake, the coffee powder bowl 14 can be removed from the inner cup 9, the coffee powder cake can be compacted in the coffee powder bowl 14, the filter sheet 3 and the coarse filter part 4 are not installed during use, the coffee powder bowl 14 is directly inserted into the bottom end of the inner cup 9, hot water is added to the outer cup 1, the inner cup 9 is inserted into the outer cup 1, and the inner cup 9 is pressed down, so that the hot water extracts the coffee powder cake in the coffee powder bowl 14 under the action of pressure.
