[0036] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.
[0037] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0039] This utility model proposes an extraction coffee machine 100, such as... Figures 1 to 3 As shown, it includes: a main body 1, an extraction cap 3, a filter assembly 4, and an immersion container 5. The main body 1 has a powder outlet. The immersion container 5 is detachably installed in the main body 1 and has a first chamber 51. The filter assembly 4 is detachably disposed in the first chamber 51 and has a second chamber 413. The extraction cap 3 is installed on the immersion container 5 and has a powder inlet 31, a water inlet 32, and at least one water inlet 33. The water inlet 33 is disposed in the water inlet 32 and the water inlet 32 is connected to the second chamber 413 through the water inlet 33. The powder outlet is connected to the second chamber 413 through the powder inlet 31.
[0040] Specifically, after the grinding assembly 2 grinds the coffee beans, the coffee powder enters from the powder outlet to the powder inlet 31 and falls into the second chamber 413 of the filter assembly 4, which is installed in the first chamber 51. By adding hot or cold water to the water inlet 32, the hot or cold water enters the second chamber 413 through the water inlet 33 and soaks and extracts the coffee powder in the second chamber 413, thus realizing the hot and cold extraction operation of coffee. In this coffee machine 100, the extraction cover 3 has a powder inlet 31 and a water inlet 32, with the water inlet 33 located in the water inlet 32. This allows the coffee powder and water to enter the second chamber 413 sequentially through the extraction cover 3, eliminating the need for separate grinding and extraction operations on two separate devices, thus improving the cumbersome operation of existing coffee machines 100 during extraction. The filter assembly 4 is used to filter coffee grounds, and the extracted coffee liquid is placed in the first chamber 51 of the steeping container 5 for people to take out and enjoy.
[0041] Preferred, such as Figure 4 and Figure 5As shown, the water inlet 32 extends circumferentially along the powder inlet 31, forming an enclosed structure. The water inlet 33 is located on the bottom wall of the water inlet 32. Specifically, since the water inlet 32 extends circumferentially along the powder inlet 31, the powder inlet 31 is located within the enclosed structure. Coffee powder falls from the powder inlet 31 into the second chamber 413, forming an upwardly protruding pile of powder in the second chamber 413. Water from the water inlet 32 flows into the second chamber 413 through the water inlet 33, flowing circumferentially along the powder pile. This allows water to seep from the periphery of the powder pile into its center, preventing the powder pile from being scattered and preventing coffee powder from splashing outside the second chamber 413. It also facilitates the soaking of the powder pile with water, further enhancing coffee extraction.
[0042] Preferred, such as Figure 5 As shown, the water inlet 32 has a symmetrical structure; there are multiple water inlets 33, which are distributed circumferentially along the water inlet 32. Specifically, by setting multiple water inlets 33 and the water inlet 32 having a symmetrical structure, when water from the water inlet 32 flows into the second chamber 413 through the multiple water inlets 33, the water flow area around the coffee grounds in the second chamber 413 is basically consistent, ensuring uniform contact between the coffee grounds and water, thereby further improving extraction efficiency. In this embodiment, the multiple water inlets 33 can be equidistantly arranged, so that the water inlet points around the coffee grounds are relatively even, allowing water to flow from the outside of the coffee grounds to the center of the coffee grounds. Moreover, the presence of multiple water inlets 33 around the coffee grounds inlet 31 allows the water required for brewing to be evenly distributed into the coffee grounds, achieving uniform soaking of the coffee grounds and improving the coffee flavor.
[0043] In some embodiments, as Figure 5 As shown, the water inlet tank 32 has a protrusion 321 and an expansion portion 322. The protrusion 321 communicates with the expansion portion 322. The protrusion 321 is close to the powder inlet 31 and has at least one water inlet 33. The expansion portion 322 is away from the powder inlet 31 and has at least one water inlet 33. Specifically, because the protrusion 321 is close to the powder inlet 31 and the expansion portion 322 is away from the powder inlet 31, water from the protrusion 321 flows into the second chamber 413 through the water inlet 33, and water from the expansion portion 322 flows into the second chamber 413 through the water inlet 33. Figure 5 As can be seen, the water flow in the protruding part 321 will be closer to the middle of the coffee grounds, while the water flow in the outward expansion part 322 will be closer to the edge of the coffee grounds. This can further ensure that the water required for brewing is evenly distributed in the coffee grounds.
[0044] In some embodiments, as Figure 2 and Figure 4As shown, the filter assembly 4 includes a first filter element 41 and a second filter element 42, which are detachably fitted to the steeping container 5. The mesh opening area of the first filter element 41 is smaller than that of the second filter element 42. Specifically, both the first filter element 41 and the second filter element 42 have a second chamber 413. When water flows into the second chamber 413 of the first filter element 41, and the mesh opening area of the first filter element 41 is smaller than that of the second filter element 42, the time for water to flow out of the first filter element 41 is longer than the time for water to flow out of the second filter element 42. The mesh is used to prevent coffee powder from being discharged into the second chamber 413 of the first filter element 41 and the second filter element 42. After the water comes into full contact with the coffee powder in the second chamber 413, it forms coffee liquid, which is then discharged through the mesh. The first filter element 41 is used to extract cold coffee, and the second filter element 42 is used to extract hot coffee. When cold extraction is required, the first filter element 41 is placed in the steeping container 5 to increase the time the water spends in the second chamber 413, so that the cold water and coffee powder are fully and evenly steeped, thus improving the taste of the coffee. When hot extraction is required, the second filter element 42 is placed in the steeping container 5 to reduce the time the water spends in the second chamber 413, thus improving the efficiency of hot extraction.
[0045] Preferred, such as Figure 6 As shown, the first filter 41 includes a first mesh portion 411 and a blocking portion 412. The first mesh portion 411 is installed at the lower end of the blocking portion 412. Specifically, since the first mesh portion 411 is at the bottom of the blocking portion 412, water flows out through the first mesh portion 411 into the first chamber 51. The blocking portion 412 increases the area of the non-mesh portion in the first filter element 41, blocking the water in the second chamber 413, further increasing the residence time of water in the second chamber 413, and preventing water from flowing out of the first filter element 41 quickly.
[0046] Preferred, such as Figure 2 and Figure 4 As shown, the filter assembly 4 has an inverted conical columnar structure. The top of the filter assembly 4 is designed to abut against the top of the soaking container 5, and the bottom of the filter assembly 4 is housed within the first chamber 51. Specifically, both the first filter element 41 and the second filter element 42 are funnel-shaped, simply to reduce the mesh area at their bottom, in order to guide and control the liquid flow, making the second chamber 413 a gradually narrowing channel. The liquid enters through the wide opening of the funnel and then flows out from the narrow opening.
[0047] Preferably, the outer diameter of the top of the filter assembly 4 is larger than the outer diameter of the water inlet trough 32. Specifically, this can increase the top area of the second chamber 413, so that the water inlets 33 of the water inlet trough 32 are all located in the second chamber 413, preventing water from flowing out of the second chamber 413.
[0048] Preferred, such as Figure 7 As shown, the second filter element 42 includes a second mesh portion 421, which is disposed on the side wall of the second filter element 42 to increase the mesh area for hot extraction by the coffee machine 100.
[0049] Preferably, the main body 1 includes a shell 11, a support 12, and a grinding assembly 2. The shell 11 is mounted on the support 12, the grinding assembly 2 is mounted inside the shell 11, and the powder outlet is located on the grinding assembly 2. The steeping container 5 is detachably connected to the support 12. Specifically, the grinding assembly 2 is used to grind coffee beans into coffee powder. The coffee powder enters the second chamber 413 of the filter assembly 4 from the powder inlet 31. The support 12 is used to support the steeping container 5 so that the coffee powder is steeped in hot or cold water in the steeping container 5 to form coffee liquid.
