[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0029] like Figures 1-6 As shown, this utility model proposes a double-layer coffee extraction structure, including a first cup body 100 and a second cup body 200. The first cup body 100 has a first filter area 101 on its cup wall and a hollow bottom with a fastener 102. The first filter area 101 includes multiple first filter holes 1011. The second cup body 200 is nested inside the first cup body 100 and fixedly connected to it. The second cup body 200 has a second filter area 201 on its cup wall, which includes multiple second filter holes 2011. The diameter of the second filter holes 2011 is smaller than that of the first filter holes 1011. The bottom of the second cup body 200 is recessed and has multiple third filter holes 202.
[0030] It should be noted that the first cup body 100 and the second cup body 200 are made of the same material, and the overall size of the second cup body 200 is smaller than that of the first cup body 100. When the second cup body 200 is nested inside the first cup body 100, the first filter zone 101 and the second filter zone 201 are opposite each other, ensuring that when the coffee powder is poured into the second cup body 200 and water is added for extraction, the coffee liquid can pass through the second filter zone 201 and the first filter zone 101 in sequence, achieving two extractions. It should be noted that the pore size of the second filter hole 2011 is smaller than that of the first filter hole 1011, which means that the coffee powder can be fully soaked in water inside the second cup body 200.
[0031] The bottom of the second cup body 200 is designed to be recessed, and the edge of the recessed bottom is designed to be angled so that when the coffee liquid drips to the bottom of the cup, it can be collected in the center of the bottom of the cup and filtered out from each of the third filter holes 202, so as to collect the extracted coffee liquid and prevent the coffee liquid from splashing to other places.
[0032] It should be added that when the second cup body 200 is placed inside the first cup body 100, the bottom of the second cup body 200 is placed inside the first cup body 100 and is higher than the bottom of the first cup body 100, so that the inner wall of the first cup body 100 surrounds the outer perimeter of the bottom of the second cup body 200. This is to prevent coffee liquid from splashing to the outside when it is filtered out from the third filter hole 202. Also, a buckle 102 is provided at the bottom of the first cup body 100 for connecting with the collection port of the corresponding coffee liquid collector, so that the cup wall of the first cup body 100 forms a delivery pipe to ensure that the coffee liquid flows directly into the coffee liquid collector.
[0033] In one embodiment of this application, the first cup body 100 and the second cup body 200 are integral structures to form an integral cup 300. It should be noted that the integral structure can be integrally molded / plasticized in terms of process, or it can be processed by secondary processing (such as welding the first cup body 100 and the second cup body 200 together).
[0034] In one embodiment of this application, the aperture of the first filter hole 1011 is in the range of 0.5mm-1.1mm, and the aperture of the second filter hole 2011 is in the range of 100 mesh-400 mesh.
[0035] It should be noted that the cup wall of the second cup body 200 adopts a filter structure, which uses small filter holes to regulate the water flow rate and avoid the water from contacting the coffee powder for too long or flowing too fast. This prevents excessive dissolution of bitterness and off-flavors, and extracts soluble substances such as aroma, sweetness, acidity, and oils. The first filter holes 1011 on the first cup body 100 are slightly larger than the second filter holes 2011 and are evenly distributed to ensure that the coffee liquid can flow out evenly and achieve uniform extraction of the entire coffee powder.
[0036] In one embodiment of this application, in order to ensure that the coffee powder can be fully mixed and soaked with water in the second cup body 200, the bottom edge of the first filter area 101 and the bottom edge of the second filter area 201 are aligned and higher than the bottom of the second cup body 200, so that there is a closed area in the integrated cup 300. In this area, the space for the coffee powder and water to be fully mixed is increased, and the residence time of the mixture of coffee powder and water in this space is delayed to ensure full soaking. Of course, the bottom edge of the first filter area 101 and the second filter area 201 can also completely cover the cup wall of the corresponding first cup body 100 and the cup wall of the second cup body 200. Alternatively, one filter area (the first filter area 101 or the second filter area 201) can completely cover the cup wall of the corresponding cup body (the first cup body 100 or the second cup body 200), while the other filter area only covers part of the cup wall of the corresponding cup body. The specific arrangement is determined according to the user's needs and is not limited here.
[0037] In one embodiment of this application, the double-layer coffee extraction structure further includes a lid 400 and a waterproof component 500. The lid 400 covers the opening of the integrated cup 300, and the waterproof component 500 is disposed between the outer wall of the lid 400 and the inner wall of the integrated cup 300. The lid 400 is provided with a filter structure 401 that connects to the inside of the integrated cup 300.
[0038] It should be noted that the opening of the integrated cup 300 has an outward-extending rim, and the edge of the lid 400 also has a lid rim. When the lid 400 closes the opening of the integrated cup 300, the lid rim adheres to the upper part of the rim, and the waterproof component 500 located on the outer wall of the lid 400 and the inner wall of the integrated cup 300 is compressed to fill the gap between the lid 400 and the integrated cup 300, thereby achieving a sealing effect on the inside of the integrated cup 300 and preventing the coffee liquid from overflowing. The lid 400 has a recessed design, and a filter structure 401 is provided in the middle. This filter structure 401 is a filter net-like structure that extends into the inside of the integrated cup 300 to filter large particles of impurities in the water, ensuring that the water used to brew the coffee powder is in a relatively clean state, thus ensuring the cleanliness and taste of the subsequent coffee liquid. The waterproof component 500 includes a silicone ring.
[0039] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
