[0047] Embodiment

[0048] Reference Figures 1-4 In the present embodiment, a coffee machine brewing device 10 is proposed, comprising a brewing cup 100, a holder 200 and a filter 300.

[0049] As Figure 5 and Figure 6 shown, the brewing cup 100 comprises a chamber 110, and the holder 200 is slidably arranged in the chamber 110. The chamber 110 is provided with a first opening 120 and a second opening 130 at two ends respectively. Among them, the holder 200, the filter 300 and the coffee powder are all put into or taken out of the chamber 110 through the first opening 120.

[0050] The filter 300 is arranged on the holder 200. Among them, inside the chamber 110, a powder cavity 101 for accommodating coffee powder is formed between the filter 300 and the first opening 120.

[0051] The holder 200 is slidably arranged in the chamber 110, wherein the holder 200 is used to slide relative to the chamber 110 so that the coffee powder can be pushed out of the first opening 120 by the holder 200.

[0052] Referring to Figure 7 and Figure 8 , the coffee powder is filled into the powder cavity 101 between the filter 300 and the first opening 120 through the first opening 120, and forms a powder cake 102 after being pressed; the high-temperature and high-pressure water liquid enters the powder cavity 101 through the first opening 120, and realizes the extraction of the coffee powder under the cooperation of the filter 300, so as to obtain concentrated coffee liquid; after the coffee making is completed, the holder 200 can be pushed by hand or tool through the second opening 130, so that the holder 200 slides towards the first opening 120. During the movement of the holder 200, the filter 300 moves synchronously, and at the same time, the filter 300 also pushes the powder cake 102 to move synchronously; when the holder 200 is pushed to slide a certain distance relative to the brewing cup 100, the powder cake 102 will be pushed out of the first opening 120.

[0053] In the process of pushing the cake 102, the cake 102 is not subjected to vibration or stirring, so that the cake 102 can maintain integrity and maintain the initial shape. Since the cake 102 can be obtained, it is beneficial to evaluate the coffee making.

[0054] Since the cake 102 is cleaned by pushing, the knocking method is no longer needed, thereby protecting the coffee maker brewing device 10, effectively prolonging the service life of the coffee maker brewing device 10, and avoiding deformation or damage of the coffee maker brewing device 10 due to knocking.

[0055] As shown in Figure 5 In this embodiment, the chamber 110 includes a first cavity 111 and a second cavity 112, the bottom of the first cavity 111 is in communication with the top of the second cavity 112, the first opening 120 is provided at the top of the first cavity 111, and the second opening 130 is provided at the bottom of the second cavity 112.

[0056] The first cavity 111 and the second cavity 112 are directly communicated, wherein the bottom surface of the first cavity 111 and the top surface of the second cavity 112 are coplanar.

[0057] The bracket 200 includes a first component 210 and a second component 220, the first component 210 is used to be installed in the first cavity 111, and the second component 220 is used to be installed in the second cavity 112. The first component 210 is slidably connected with the first cavity 111, and the second component 220 is slidably connected with the second cavity 112.

[0058] The filter 300 is arranged on the first component 210. The powder cavity 101 is located in the interior of the first cavity 111.

[0059] The cross-sectional area of the first cavity 111 is greater than the cross-sectional area of the second cavity 112, wherein the bottom surface of the first cavity 111 is used to support the first component 210. The bottom surface of the first cavity 111 is an annular surface.

[0060] The cross-sectional shape of the first cavity 111 is circular, elliptical or polygonal, and the cross-sectional shape of the second cavity 112 is circular, elliptical or polygonal.

[0061] In this embodiment, the cross-sectional shape of the first cavity 111 and the second cavity 112 is circular, specifically, the first cavity 111 and the second cavity 112 are both cylindrical structures, and are coaxially arranged. The outer contour of the first component 210 and the second component 220 is also a cylindrical structure, and the outer diameter of the first component 210 is greater than the outer diameter of the second component 220.

[0062] In other embodiments, the shapes of the first cavity 111 and the second cavity 112 can be set as needed. For example, the cross-sectional shape of the first cavity 111 can be set to an ellipse or a polygon, and the cross-sectional shape of the second cavity 112 can be set to an ellipse or a polygon. Among them, polygons include triangles, quadrilaterals, pentagons, hexagons, etc.

[0063] Reference Figure 5 and Figure 6 As shown, an elastic sealing element 230 is fitted onto the outer wall of the second component 220. The sealing element 230 is used to seal against the inner wall of the second cavity 112. The sealing element 230 can be a sealing ring made of rubber, silicone, or other elastic materials.

[0064] like Figures 9-10 As shown, a mounting groove 221 is provided on the outer wall of the second component 220. The mounting groove 221 has an annular structure and is arranged circumferentially along the outer wall of the second component 220. A sealing element 230 is disposed in the mounting groove 221, and a portion of the sealing element 230 protrudes outside the mounting groove 221. First, the sealing element 230 is installed in the mounting groove 221 of the second component 220. When the second component 220 is inserted into the second cavity 112, the portion of the sealing element 230 protruding outside the mounting groove 221 contacts the inner wall of the second cavity 112 and undergoes elastic deformation, thereby achieving a seal.

[0065] like Figure 9 As shown, one end of the support 200 is provided with a cavity 240, and a support protrusion 250 is provided within the cavity 240 to support the filter element 300. There are multiple support protrusions 250, and any two adjacent support protrusions 250 are spaced apart, thereby ensuring that the coffee liquid can flow smoothly and drain without obstruction. In this embodiment, the cavity 240 is located at the top of the first component 210.

[0066] The cross-sectional shape of the support protrusion 250 can be arc-shaped, polygonal, circular, elliptical, etc. The number of support protrusions 250 can be set as needed, but it must ensure that it can provide stable support for the filter element 300 and prevent the filter element 300 from shifting or deforming due to pressure. The height of the support protrusion 250 can be the same as the depth of the cavity 240.

[0067] In this embodiment, the cross-sectional shape of the support protrusion 250 is arc-shaped, and a certain number of support protrusions 250 are distributed in both the radial direction along the cavity 240 and the circumferential direction parallel to the cavity 240.

[0068] The bracket 200 is provided with a drainage through hole 260, which is arranged along the axial direction of the bracket 200. The drainage through hole 260 is in communication with the recessed cavity 240. The drainage through hole 260 penetrates the first component 210 and the second component 220, and in the Figure 6 In the embodiment, the drainage through hole 260 is a stepped hole.

[0069] The coffee liquid flows into the recessed cavity 240 after passing through the filter 300, and then flows to the drainage through hole 260, so as to be discharged. Since the second component 220 is sealed and matched with the inner wall of the second cavity 112 through the sealing member 230, the liquid (including water and coffee liquid) can be ensured to be discharged from the drainage through hole 260 after passing through the filter 300, and will not leak from the gap between the second component 220 and the second cavity 112. The filter 300 can be a filter screen, wherein a plurality of filter screen holes are arranged on the filter 300, and the filter screen holes are used for the coffee liquid to flow through.

[0070] As shown in Figure 9 and Figure 11 The bracket 200 is provided with a positioning structure 270, and the filter 300 is provided with a matching structure 310 corresponding to the positioning structure 270. The positioning structure 270 is used to cooperate with the corresponding matching structure 310 to position the filter 300. The positioning structure 270 and the matching structure 310 are matched with each other to realize the positioning of the filter 300 on the bracket 200.

[0071] In the positioning structure 270 and the matching structure 310, one is a groove body and the other is a column body, wherein the column body is used to be inserted into the groove body.

[0072] The positioning structure 270 can be arranged in the recessed cavity 240, and the matching structure 310 can be arranged on the outer periphery of the filter 300. The matching structure 310 can be arranged in an annular array about the center of the filter 300.

[0073] The positioning structure 270 and the matching structure 310 are fixedly connected. The positioning structure 270 and the matching structure 310 can be fixedly connected by using a fixing mode such as fusion, welding or adhesion according to the materials of the bracket 200 and the filter 300.

[0074] The brewing cup 100 is provided with a handle 400, so as to facilitate the user to hold.
