The process of extracting coffee powder by hot water through the built-in filter basket 110 and then directly flowing into the coffee cup is generally adopted. However, the coffee machine has certain defects in the extraction process of the coffee powder. Since the hot water directly flows into the coffee cup after being extracted through the coffee powder, it can be understood that the closing structure of the liquid outlet 112 of the filter basket 110 is opened by gravity, so that the extraction is not thorough enough, and the concentration of the coffee cannot be flexibly adjusted.

[0052] The following will be described in combination with Figures 1-9 The extraction device for the coffee machine and the coffee machine of the utility model embodiment are described. In the utility model embodiment, the coffee machine includes the above-mentioned extraction device for the coffee machine.

[0056] Therefore, it can be understood that the coffee powder is placed in the extraction cavity 111 and extracted by hot water, the coffee liquid discharge time is controlled by the switch under the same powder-water ratio, the change of the coffee concentration is realized, and the coffee powder extraction is more sufficient.

[0057] Specifically, referring to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , in the embodiment of the utility model, the sealing mechanism 200 is movably arranged in the extraction assembly 100. By movably arranging the sealing mechanism 200, a more flexible and convenient control mode can be provided for the user, so that the position or state of the sealing mechanism 200 can be adjusted at any time according to the needs, which can help to optimize the space utilization.

[0060] Among them, the sealing part 221 abuts against the liquid outlet 112 at the first position, the actuating mechanism 300 drives the transmission part 211 at the second position, and the sealing part 221 can move with the sealing mechanism 200 to have a gap between the liquid outlet 112.

[0061] With the above structure, by pushing the actuating mechanism 300 to move, the actuating mechanism 300 is in transmission cooperation with the transmission part 211 to drive the blocking mechanism 200 to move, when the blocking mechanism 200 moves to the sealing part 221 and the liquid outlet 112 has a gap, to open the liquid outlet 112, the extraction liquid, that is, the coffee liquid, can flow into the liquid outlet 112 through the gap to flow to the coffee cup through the liquid outlet 112; on the contrary, when the actuating mechanism 300 is pushed to move reversely, the blocking mechanism 200 moves to the sealing part 221 and the liquid outlet 112 abuts, that is, the sealing part 221 abuts the inner edge of the liquid outlet 112, thereby blocking the coffee liquid from flowing out through the liquid outlet 112, the user can accurately control the start and end of the liquid outlet, control the extraction time, avoid unnecessary waste, the structure is simple, and the operation is convenient.

[0062] Specifically, referring to Figure 2 , Figure 3 , Figure 5 and Figure 6 , in the embodiment of the utility model, the blocking mechanism 200 includes the blocking piece 210 and the sealing piece 220, the blocking piece 210 is movably arranged on the filter basket 110 and the base 120 of the extraction assembly 100, and the blocking piece 210 is arranged corresponding to the liquid outlet 112, the transmission part 211 is formed on the blocking piece 210, the sealing piece 220 is arranged on the blocking piece 210, and the sealing piece 220 is arranged in the extraction cavity 111, wherein the transmission part 211 is arranged on the blocking piece 210, and the sealing part 221 is arranged on the sealing piece 220.

[0063] With the above structure, the blocking piece 210 can be movably arranged on the extraction assembly 100 and arranged corresponding to the liquid outlet 112, and the above design enables the blocking piece 210 to move to a relative position cooperating with the liquid outlet 112 according to the transmission of the actuating mechanism 300 and the transmission part 211, so that the sealing part 221 of the sealing piece 220 cooperates with the liquid outlet 112 to open or close.

[0068] It should be further noted that in the embodiment of the utility model, the above-mentioned plugging piece 210 and sealing piece 220 are detachably connected by sleeving. The cross-sectional area formed by the cooperation of the above-mentioned sealing ring and the plugging piece 210 is greater than the cross-sectional area of the liquid outlet 112, so as to avoid the separation of the plugging mechanism 200 from the extraction assembly 100 and ensure the stable opening and closing control. Of course, it can be understood that in the embodiment of the utility model, the cross-sectional area of the above-mentioned plugging piece 210 corresponding to the liquid outlet 112 is smaller than the cross-sectional area of the liquid outlet 112, so as to facilitate the quick disassembly and maintenance of the plugging piece 210 after the sealing piece 220 is disassembled, and the operation is convenient.

[0069] Of course, in some embodiments, the above-mentioned plugging piece 210 and sealing piece 220 can also be an integral molding structure. The plugging piece 210 and the sealing piece 220 are simultaneously injection molded during injection molding, or the plugging piece 210 is simultaneously formed with the transmission part 211 and the sealing part 221, which is not limited here.
