[0043] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0044] Example 1:

[0045] like Figure 1 As shown, a coffee machine is presented, which includes a cup body 10 and a mounting bracket 9 at one end of the cup body 10. The mounting bracket 9 is connected to a powder extraction assembly, and a cup 30 is provided on the outside of the powder extraction assembly to receive the extracted coffee.

[0046] Meanwhile, the specific structure of the coffee powder extraction assembly is as follows: it includes a top cover 1 and an extraction chamber 2, with a coffee bowl 3 positioned between the top cover 1 and the extraction chamber 2, and a pressing part 11 on the outside of the top cover 1. Furthermore, the bottom structure of the coffee bowl 3 is as follows: the coffee bowl 3 has several filter holes with a diameter of approximately 0.3 mm, and the coffee bowl 3 can hold at least 10g of coffee powder. A sealing ring 41 is positioned between the bottom of the coffee bowl 3 and the extraction chamber 2, and the sealing ring 41 is located outside the filter holes.

[0047] Thus in actual use, the water is prevented from flowing to other places by the sealing ring 41 and the cooperation between the sealing ring 41 and the filter hole.

[0048] Secondly, the structure of the top of the powder bowl 3 is as follows: firstly, the top of the powder bowl 3 is provided with a mounting portion 31, and the mounting portion 31 is located between the pressing portion 11 and the top of the extraction chamber 2, and a connecting groove 311 is formed in the bottom of the mounting portion 31 and corresponds to the top of the extraction chamber 2.

[0049] Thus in actual use, the powder bowl 3 is connected and limited by the extrusion of the pressing portion 11 and the top of the extraction chamber 2 on the mounting portion 31, and secondly, in order to make the connection more stable, the connecting groove 311 is formed in the bottom of the mounting portion 31, so as to be matched with the top of the extraction chamber 2.

[0050] Moreover, compared with the plate-shaped filter screen, the installation of the powder bowl 3 is convenient, and the powder bowl 3 can be directly placed in the correct direction without multiple adjustments and tilting, and the powder bowl 3 itself is difficult to move in the extraction chamber 2. Moreover, the powder bowl 3 is made of metal, so compared with the plate-shaped filter screen, the contact between water and plastic parts can be greatly reduced.

[0051] Secondly, in order to make the installation of the powder bowl 3 more stable, the elastic member two 7 is arranged, and the specific structure is as follows: Figure 3 As shown in the figure, firstly, the upper cover 1 comprises a main body two and a pressing portion 11 located on the outer side of the top of the main body two, and the inner wall of the extraction chamber 2 is provided with the elastic member two 7, and the inner wall of the elastic member two 7 is provided with at least one protruding portion 71, and the protruding portion 71 cooperates with the outer side of the main body two to abut against the powder bowl 3.

[0052] Thus in actual use, the protruding portion 71 cooperates with the outer side of the main body two to abut against the powder bowl 3, so as to make the installation of the powder bowl 3 more stable.

[0053] The installation of the elastic member two 7 is that the inner wall of the extraction chamber 2 is grooved to place the elastic member two 7. Moreover, the outer side of the main body two is further provided with a sealing ring two 44, and the protruding portion 71 and the sealing ring two 44 are located on both sides of the side wall of the powder bowl 3, and the protruding portion 71 and the sealing ring two 44 are matched to abut against the powder bowl 3, so as to make the installation of the powder bowl 3 more stable.

[0054] It should be noted that the above-mentioned way of stably installing the powder bowl 3 in the extraction chamber 2 by the elastic member two 7 is a detachable assembly way, and in addition to this way, the powder bowl 3 can be fixed in the extraction chamber 2 by welding, interference fit and other ways.

[0055] As shown in the figure, Figures 3-6As shown, the installation structure of the sealing ring 41 is as follows: First, the bottom of the extraction chamber 2 is provided with a liquid outlet 21, and the bottom surface of the extraction chamber 2 is provided with an installation groove 22 outside the liquid outlet 21, and the sealing ring 41 is located in the installation groove 22.

[0056] Meanwhile, the structure of the sealing ring 41 itself is as follows: First, the sealing ring 41 includes a main body 411 and a protrusion 412 set on the top of the main body 411. The protrusion 412 is located outside several filter holes and contacts the bottom of the powder bowl 3. The inner and outer sides of the protrusion 412 are both inclined surfaces, and the inclined surfaces are inclined towards the liquid outlet 21.

[0057] Therefore, in actual use, since the bottom of the powder bowl 3 generally does not directly and completely contact the inner bottom surface of the extraction chamber 2, the protrusion 412 is designed to make up for this gap. Moreover, it is set at an angle and faces the liquid outlet 21, which can increase the contact area between the liquid and the sealing ring 41, thereby playing a buffering role.

[0058] Furthermore, in order to save costs, the upper and lower parts of the main body 411 can be made to be different. Therefore, the outer side of the upper part of the main body 411 abuts against the inner side wall of the mounting groove 22, and the lower part is smaller than the upper part.

[0059] like Figures 3-10 As shown, hot water comes out from the mounting bracket 9 and flows out through the top cover 1, the portafilter 3, the extraction chamber 2 and the base 5. A structure is set between the extraction chamber 2 and the base 5 to control whether the liquid flows out, thereby effectively preventing residual coffee in the extraction chamber 2 from seeping out and causing stains to the outside, thus making it easy to clean and maintain.

[0060] The specific structure is as follows: First, the present invention also includes a base 5, and the extraction chamber 2 is located between the upper cover 1 and the base 5. The bottom of the extraction chamber 2 is provided with a liquid outlet 21, and the bottom of the base 5 is provided with a liquid outlet hole 51 corresponding to the liquid outlet 21. Furthermore, an elastic element 61 is provided between the extraction chamber 2 and the base 5, and a plug 62 is provided on the elastic element 61 corresponding to the liquid outlet 21.

[0061] Therefore, in actual use, the top of the stopper 62 is located inside the liquid outlet 21 under the action of the elastic element 61, so that the liquid outlet 21 and the liquid outlet 51 are not connected. The water applies force to the stopper 62, causing the stopper 62 to move down and thus connect the liquid outlet 21 and the liquid outlet 51.

[0062] The structure of the elastic element 61 is as follows: First, a bottom cover 63 is provided between the extraction chamber 2 and the base 5, and the bottom cover 63 has an outlet 632 corresponding to the liquid outlet 21. The elastic element 61 is located between the bottom cover 63 and the extraction chamber 2, and the movement of the plug 62 can control whether the liquid outlet 21 and the outlet 632 are connected.

[0063] This is because in actual use, the base 5 will be provided with a burst plate 20, when the extraction bin 2 and the powder bowl 3 are removed and the capsule is placed, the burst plate 20 will play a role in puncturing the capsule. Therefore, in order to avoid the influence of the elastic piece 61 on the burst plate 20, the bottom cover 63 is provided to separate the elastic piece 61 and the burst plate 20.

[0064] At the same time, the bottom cover 63 is provided with at least two placing grooves 631, and the elastic piece 61 includes a connecting portion 611 and a spring piece 612 located outside the connecting portion 611, and the connecting portion 611 is provided with a plug 62 corresponding to the outlet 21, and the spring piece 612 is inclinedly arranged, and the end of the spring piece 612 away from the connecting portion 611 is located in the placing groove 631.

[0065] Therefore, in actual use, by locating the end of the spring piece 612 away from the connecting portion 611 in the placing groove 631, the relative rotation is limited, and in order to install more stably, four spring pieces 612 can be provided.

[0066] Moreover, the structure between the plug 62 and the connecting portion 611 is that: first, the plug 62 is provided with a clamping block 621 at the bottom, and the connecting portion 611 is provided with a hole corresponding thereto, and the outer side of the bottom cover 63 is provided with a sealing piece 42. The bottom surface of the sealing piece 42 is provided in a stepped surface, which can increase the contact area with the burst plate 20, thereby preventing water from flowing to other places.

[0067] As shown in the figure, Figures 3-10 The related structure of the upper cover 1 is that: first, the upper cover 1 is provided with a hole 12 for water flow, and the upper cover 1 is provided with a water inlet net 81 and a water outlet net 82 on the upper and lower sides of the hole 12, and the hole diameter of the water inlet net 81 and the water outlet net 82 is about 0.3mm.

[0068] Therefore, in actual use, by providing the water inlet net 81 and the water outlet net 82, the function of separating multiple water paths can be achieved, and during the extraction process, it can also block the coffee powder and coffee liquid that may splash.

[0069] The installation of the water inlet net 81 is that: first, the upper cover 1 is provided with a placing groove 13, and the placing groove 13 is provided with a protrusion 131, and the water inlet net 81 is placed in the placing groove 13 and provided with a clamping groove 811 corresponding to the protrusion 131.

[0070] Moreover, the installation of the water outlet net 82 is that: first, the bottom of the upper cover 1 is provided with a protrusion 14, and the water outlet net 82 is provided with a clamping hole 821 corresponding to the protrusion 14, and the bottom of the upper cover 1 is further provided with a support column 15 on one side of the water outlet net 82, thereby supporting the water outlet net 82.

[0071] And in order to connect more stably, screws or the like can be provided for fastening.

[0072] As shown in Figure 14 and Figure 15 The structure between the mounting frame 9 and the upper cover 1 is that: first, the mounting frame 9 is provided with a channel 91 for water flow, and the upper cover 1 is provided with a hole 12, and the mounting frame 9 is provided with a sealing piece one 45 on the side close to the upper cover 1.

[0073] Meanwhile, the mounting frame 9 is provided with a mounting hole 92, and the mounting frame 9 is provided with a clamping groove 93 on the outside of the channel 91, and the sealing piece one 45 is provided with a clamping block 451 corresponding to the mounting hole 92, and the sealing piece one 45 is provided with a clamping part 452 corresponding to the clamping groove 93, and the sealing piece one 45 is provided with a through hole 453 corresponding to the channel 91. Moreover, the bottom of the sealing piece one 45 is provided with a sealing surface, and the sealing surface abuts against the upper cover 1 and is located outside the hole 12 to avoid water flowing outward.

[0074] Therefore, in actual use, compared with separately providing a sealing piece for the mounting hole 92 and the channel 91, the utility model realizes two sealing by one sealing piece one 45, that is, one piece is used for multiple purposes, so the structure is more simplified, and the installation is more convenient.

[0075] Embodiment two: the embodiment is basically the same as embodiment one, and the difference lies in the structure of the plug and the position and assembly relationship, as shown in Figures 11-13 The plug in embodiment two adopts a structure of plug two 64, and the plug two 64 is arranged in the base 5, and at this time, the extraction bin 2 is not provided with the plug one 62, the elastic piece one 61 and the bottom cover 63.

[0076] Specifically, the outlet hole 51 on the base 5 is built-in with the plug two 64, the plug two 64 is provided with a gap 641, the gap 641 is in a closed state, and the gap 641 is forced to open.

[0077] Therefore, when not in use, the gap 641 is in a closed state, and when hot water flows down, the gap 641 is forced to open.

[0078] Meanwhile, the structure of the plug two 64 is that: first, the top of the plug two 64 is provided with a groove 642 in communication with the gap 641, so as to reduce the thickness of the gap 641, and then the gap 641 is more convenient to open. Moreover, the plug two 64 is provided with an assembly part 643 on the side, and the base 5 is provided with an assembly groove corresponding to the assembly part 643, so that the assembly part 643 and the assembly groove are matched to realize the installation.

[0079] Secondly, the bottom outer side of the extraction bin 2 is provided with a sealing piece three 43, and the bottom surface of the sealing piece three 43 is provided in a stepped surface, which can increase the contact area with the expansion plate 20, thereby preventing water from flowing to other places. Specifically, the sealing piece three 43 and the extraction bin 2 are detachably fixedly connected, and the sealing piece three 43 is provided with a limiting groove on the surface, which is matched with the locking shackle ring of the extraction bin 2. Therefore, when assembling, only the limiting groove on the sealing piece three 43 is clamped with the locking shackle ring, so that the sealing piece three 43 is convenient to install or replace. Figure 11 As can be seen, the bottom of the extraction bin 2 is formed with a locking shackle ring arranged in a ring shape, and the surface of the sealing piece three 43 is provided with a limiting groove matched with the locking shackle ring. Therefore, when assembling, only the limiting groove on the sealing piece three 43 is clamped with the locking shackle ring, so that the sealing piece three 43 is convenient to install or replace.

[0080] The basic principle and main characteristics of the utility model and the advantages of the utility model are shown and described above. Meanwhile, the utility model is not limited by the above-mentioned embodiments, so that various changes and improvements of the utility model can be made without departing from the principle and scope of the utility model.
