[0063] Specific embodiments of the present invention will be described in more detail below with reference to the drawings.

[0064] As shown in Figure 1, the coffee machine includes a machine body 20, a heating area at one end of the machine body 20, a mounting frame 1 at the other end of the machine body 2, a brewing assembly built into the mounting frame 1, and a cup 10 for receiving the brewed coffee mounted on the outside of the mounting frame 1. The machine body 20 also houses a water pump for moving water from the heating area to the brewing assembly, as well as a main circuit board for controlling the operation of each component, and an anti-slip ring 201 may be fitted on the outside of the machine body 20 to make it easier for the user to grip and prevent the hand from slipping.

[0065] In addition, in conventional structures, the position of the cup 10 is generally fixed and cannot be flexibly adjusted, whereas in the present invention, an adjustment assembly is provided to allow the cup 10 to move, and the specific structure is as follows: First, the expandable container assembly includes a mounting frame 1 and a cup 10 fitted to the outside of the mounting frame 1. The space between the cup 10 and the mounting frame 1 is a storage space for storing liquid, and an adjustment assembly is provided between the mounting frame 1 and the cup 10 to expand or contract the storage space.

[0066] Therefore, by installing an adjustment assembly to expand or shrink the storage space during actual use, the size of the storage space can be adjusted, and it can be flexibly adjusted according to actual conditions, and the storage space can be reduced when not in use, making it easier to carry. Furthermore, the adjustment assembly can be adapted not only to coffee machines but also to other drinking cups.

[0067] Here, the structure of the adjustment assembly can be varied. For example, the adjustment assembly may include a grooved rail 21 and a first slider 22, and the first slider 22 performs adjustment by moving within the grooved rail 21. Furthermore, the positions of the grooved rail 21 and the first slider 22 are not fixed, and may be provided on the mounting frame 1 or on the cup 10.

[0068] Therefore, the adjustment assembly has two types of structures, namely, the groove rail 21 is installed on the outside of the mounting frame 1, and the first slider 22 is located inside the cup 10, and the first slider 22 is located inside the groove rail 21 and slides along the groove rail 21 to adjust the position of the cup 10 and expand or contract the storage space.

[0069] Alternatively, the groove rail 21 is provided inside the cup 10, and the first slider 22 is located outside the mounting frame 1, and the first slider 22 is located inside the groove rail 21 and slides along the groove rail 21, thereby adjusting the position of the mounting frame 1 to expand or reduce the storage space.

[0070] 1, the specific structures of the grooved rail 21 and the first slider 22 are as follows: First, there are at least two grooved rails 21, which correspond one-to-one to the first sliders 22. The grooved rail 21 includes a first lateral segment 211, a second lateral segment 212, and a connecting segment 213 for connecting the first lateral segment 211 and the second lateral segment 212. In actual use, the first slider 22 moves back and forth between the two lateral segments along the connecting segment 213 to expand or reduce the storage space.

[0071] Next, details of other structures will be described by taking as an example a structure in which the groove rail 21 is provided on the outside of the mounting frame 1 and the first slider 22 is located inside the cup 10. First, a first stopper 241 is built into the first horizontal segment 211, and a first locking groove 221 is formed in the first slider 22 corresponding to the first stopper 241. Therefore, during actual use, the first stopper 241 and the first locking groove 221 are fitted together to restrict the movement of the cup 10, and further, movement of the cup 10 can be prevented when not in use.

[0072] Furthermore, since the angle formed between the lower side of the first horizontal segment 211 and the connecting segment 213 is 90° or more, the connecting segment 213 may be a straight line, a diagonal line, or a spiral.

[0073] An arc-shaped segment is provided between the upper side of each second lateral segment 212 and the connecting segment 213, so that two adjacent second lateral segments 212 do not communicate with each other. Therefore, in actual use, the arc-shaped segment can reduce wear, and because two adjacent second lateral segments 212 do not communicate with each other, it can be seen that the first slider 22 has moved to a more accurate position when it abuts against the inner wall of the second lateral segment 212. Next, the length of the second lateral segment 212 is longer than that of the first slider 22, which makes it easier for the first slider 22 to move, and the length of the second lateral segment 212 is shorter than an equal unit of the circumference of the mounting frame 1 or cup 10, so that two adjacent second lateral segments 212 do not communicate with each other.

[0074] As shown in Fig. 1, for easier use, the cup 10 is made of a transparent or opaque material, allowing the adjustment assembly to be seen and easier to operate. A third seal ring 36 is provided between the mounting frame 1 and the cup 10, and a notch 361 for exhaust is provided on the outside of the third seal ring 36 to prevent excessive internal air pressure. The notch 361 is formed by providing a second protrusion on the outside of the third seal ring 36, and the notch 361 is provided between two adjacent second protrusions.

[0075] As shown in Figures 2 to 15, the brewing assembly includes a water inlet seat 41 and a base 45, and the structure between the water inlet seat 41 and the base 45 can be various, for example, it can be fitted to the powder pot outer bowl 42, or it can be fitted to the powder bowl 43, or it can be fitted to a fitting break-off plate 49, etc.

[0076] When the extraction assembly has the third structure, this third extraction assembly is used to extract Nespresso capsules and capsules of the same size, that is, the water inlet seat 41 and the base 45 are fitted with a combination of a push-break plate 49 and a piercing needle 446, that is, the piercing needle 446 first pierces the top of the capsule to let water in, and the push-break plate 49 pierces the bottom of the capsule to let water out, as shown in Figures 16 and 17, first, the water inlet seat 41 is a capsule pot water inlet seat, and the capsule pot water inlet seat An extraction capsule pot is formed between the seat and the base 45, a push-break plate 49 is provided within the extraction capsule pot, the push-break plate 49 is provided on the base 45, the capsule pot water inlet seat forms a first cavity that fits the coffee capsule, a piercing needle 446 is provided at the upper end of the capsule pot water inlet seat, the capsule pot water inlet seat is fitted into the base 45 to clamp the edge of the capsule, and a fifth sealing member 37 is further provided between the water inlet seat 41 and the push-break plate 49 to prevent the liquid from flowing in other directions.

[0077] A third stopper with a wavy upper surface is provided on the inner wall of base 45, and a first position limiting groove corresponding to the third stopper is formed on the outer bottom surface of water inlet seat 41. During actual use, the engagement between the third stopper and the first position limiting groove limits the relative rotation of water inlet seat 41 and base 45.

[0078] As shown in Figures 18 to 22, when the extraction assembly has the fourth structure, it includes a piercing assembly, which specifically includes a water inlet seat 41, a second mounting plate 44, and a piercing needle 446 located between the water inlet seat 41 and the second mounting plate 44, and the water inlet seat 41 has a plurality of water inlets 412 for allowing water to flow through.

[0079] Next, the second mounting plate 44 has a second cavity opened below the water inlet 412, a second passage 441 communicating with the second cavity is provided within the second cavity, the bottom of the piercing needle 446 is movably provided within the second passage 441, and the top of the piercing needle 446 penetrates the water inlet seat 41 and is exposed. Also, a third passage 4461 for circulating water is opened in the middle of the piercing needle 446, and a side port 4462 for communicating the second cavity with the third passage 4461 is opened in the side wall of the piercing needle 446.

[0080] Therefore, during actual use, when water flows into the second mounting plate 44, it can enter the third passage 4461 from the side port 4462 and then flow into the capsule 70, thereby significantly reducing the accumulation of water on the second mounting plate 44.

[0081] Here, the number of side ports 4462 can be selected according to the actual situation. For example, a side port 4462 communicating with the third passage 4461 is opened on both sides of the piercing needle 446, and the two side ports 4462 are arranged symmetrically.

[0082] To prevent excessive water from seeping in, the second passage 441 is designed to be formed by surrounding at least two third protruding plates 442, with a gap between two adjacent third protruding plates 442. Therefore, in actual use, the third protruding plates 442 and the gaps are used to realize flow separation, and the number of third protruding plates 442 can be selected according to actual conditions. For example, the second mounting plate 44 has four third protruding plates 442 on the outside of the second passage 441.

[0083] Furthermore, during actual use, the second mounting plate 44 is positioned within the water inlet seat 41 and is attached and fixed by screws, and the water inlet seat 41 needs to be removed from the base 45 in order to place the capsule within the base 45. Therefore, the position of the piercing needle 446 after it has returned is important; if it does not return completely to the inside, it may be exposed and injure the user.

[0084] For this reason, the second mounting plate 44 has a boss 443 below the second passage 441, and the boss 443 has a second through hole 444 communicating with the second passage 441. A spring 447 is provided between the boss 443 and the piercing needle 446, and the bottom of the piercing needle 446 is positioned within the second through hole 444 by the action of the spring 447.

[0085] Therefore, in actual use, the installation of the boss 443 can increase the length of the second passage 441, thereby preventing the piercing needle 446 from penetrating through the second mounting plate 44 and being exposed even after returning, and further preventing the piercing needle 446 from injuring the user.

[0086] In addition, in order to prevent the spring 447 from falling out of the second passage 441, the diameter of the second through-hole 444 is designed to be smaller than the diameter of the second passage 441.

[0087] In addition, a position limiting plate 4463 is provided on the outside of the piercing needle 446, and a spring 447 is located between the bottom of the position limiting plate 4463 and the boss 443, and the top of the position limiting plate 4463 can abut against the water inlet seat 41, thereby limiting the movement range of the piercing needle 446.

[0088] Therefore, in actual use, the installation of the position limiting plate 4463 can realize the multiple uses of one component, that is, it can limit the spring 447 and press the spring 447, while further limiting the movement range of the piercing needle 446.

[0089] As shown in Figure 4, the structure of water inlet seat 41 is as follows: First, a first groove 416 is formed at the top of water inlet seat 41, a third through-hole is formed at the bottom of first groove 416 to allow piercing needle 446 to pass through, and first groove 416 has a water inlet 412 formed outside the third through-hole.

[0090] Therefore, in actual use, the installation of the first groove 416 can avoid interference with other components, and compared to a flat surface, the installation of the first groove 416 can further restrict the position of water and prevent it from flowing in other directions.

[0091] 19 and 20, the sealing structure is as follows: First, a fourth seal ring 381 is provided between the inner wall of the water inlet seat 41 and the outer wall of the second mounting plate 44. The water inlet seat 41 and the second mounting plate 44 are connected with screws.

[0092] In addition, a first baffle 418 is provided within the water inlet seat 41, a support plate 445 is provided on the second mounting plate 44, the inner wall of the support plate 445 is surrounded to form a cavity, and the support plate 445 is positioned within the first baffle 418 and a fifth seal ring 382 is provided between the support plate 445 and the water inlet seat 41.

[0093] When the extraction assembly is of the fourth structure, it further includes a base 45 and a break-through assembly as described in any one of the above, wherein the base 45 has a mounting cavity formed therein for placing the capsule 70, a liquid outlet is opened at the bottom of the base 45, the top of the base 45 is located within the water inlet seat 41, the second mounting plate 44 is located between the base 45 and the water inlet seat 41, and the inner wall of the water inlet seat 41 and the outer wall of the base 45 are removably connected.

[0094] The removable connection structure here can be various, and can be a threaded connection or a rotary snap fit, and therefore, as a specific structure, a threaded connection can be used between the inner wall of the water inlet seat 41 and the outer wall of the base 45.

[0095] Alternatively, a slide groove 417 with one side open is formed on the inner wall of the water inlet seat 41, a sixth locking groove 4171 is formed within the slide groove 417, and a second slider 452 is provided on the outer wall of the base 45.

[0096] Therefore, during actual use, the second slider 452 enters the slide groove 417 through the opening and moves along the slide groove 417. The second slider 452 has a fifth protrusion 4521 that corresponds to the sixth locking groove 4171. Rotation is restricted by the engagement between the sixth locking groove 4171 and the fifth protrusion 4521. When removal is required, a large force can be applied to release the position restriction, allowing the water inlet seat 41 and base 45 to be separated.

[0097] The capsule 70 that can be placed on the base 45 is a commercially available aluminum capsule, such as a DG capsule, a Nestle capsule, or a Starbucks capsule. The internal structure of each capsule is different. For example, the Nestle capsule is entirely sealed and contains ground coffee, while the DG capsule has a filtering structure attached to its interior and a filtering hole at its bottom. Therefore, different structures can be selected for the base 45 depending on the capsule.

[0098] The drawing shows the base of the DG capsule, and when the DG capsule is placed in the base 45, the piercing needle 446 pierces the top of the capsule 70, and the coffee liquid flows out through the filter hole at the bottom and out of the second liquid outlet 451 of the base 45.

[0099] As another structural feature, a sixth seal ring 383 is provided between the outer wall of the base 45 and the inner wall of the water inlet seat 41. A second connecting plate 701 is provided on the outside of the top of the capsule 70, and a step is provided on the inner wall of the water inlet seat 41. The second connecting plate 701 is positioned between the step and the base 45, and the bottom of the second mounting plate 44 abuts against the second connecting plate 701.

[0100] When the extraction assembly is of the fourth structure, the mounting frame of the coffee machine body that is compatible with it preferably has a first passage 11 through which water flows, and at least one overflow groove that communicates with the first passage 11.

[0101] Therefore, in actual use, the overflow groove is provided to enlarge the drainage diameter, allowing for faster drainage and accommodating multiple water inlets 412.

[0102] It should be noted that the diameter of the first passage 11 is smaller than the diameter of the piercing needle 446, and the first passage 11, together with the overflow groove, forms a drainage structure in the shape of a cross, which is different in shape from the piercing needle 446. Thus, after the assembled brewing structure is attached to the mounting frame 1 of the coffee machine via the water inlet seat 41, the piercing needle 446, while connected to the drainage structure, is pressed by the drainage structure, and the tip of the piercing needle 446 initially pierces the surface of the capsule 70, facilitating subsequent brewing. After brewing is completed, when the brewing structure is removed from the mounting frame 118, the piercing needle 446 loses its pressing force and automatically retracts, hiding within the boss 443.

[0103] Therefore, in an application scenario in which a user extracts coffee using a capsule, a DG capsule will be used as an example. When a capsule 70 is placed in the base 45 and the piercing assembly is placed in a coffee machine, the piercing needle 446 of the piercing assembly initially moves downward due to the mounting frame 1 and then moves further downward due to the force of the water, piercing the capsule 70 and achieving further pressure extraction. It should be noted that because the DG capsule has a capsule structure with a pressure retention function, coffee liquid can be extracted without using the base 45. Alternatively, a corresponding base 45 can be selected depending on the type of capsule. For example, the base 45 may further adopt the cup in the utility model application number 2021221884101.

[0104] 2 to 9, the brewing assembly has a first structure, which is used for brewing ground coffee. That is, the space between the water inlet seat 41 and the base 45 is adapted to fit the combination of the powder pot outer bowl 42 and the powder bowl 43. The coffee powder enters the powder bowl 43 without passing through the filtering holes of the powder bowl 43, and the powder bowl 43 can accommodate at least 10g of ground coffee. The specific structure is as follows: the water inlet seat 41 is the powder pot water inlet seat, and the brewed powder pot or brewed capsule pot is formed between the powder pot water inlet seat and the base 45, respectively. The brewed powder pot is provided with the powder pot outer bowl 42 containing the powder bowl 43. The water inlet seat 41 covers the powder bowl 43 and is fitted into the powder pot outer bowl 42 to sandwich the powder bowl 43.

[0105] The structure of the powder bowl 43 is as follows: First, a pressing part 411 is provided on the outside of the water inlet seat 41, and a plurality of filter holes are provided at the bottom of the powder bowl 43. The bottom of the powder bowl 43 is located within the outer bowl 42 of the powder pot, and a first sealing ring 31 is provided between the powder bowl 43 and the outer bowl 42 of the powder pot, and the first sealing ring 31 is located outside the plurality of filter holes. Therefore, in actual use, the first sealing ring 31 and its combination with the filter holes prevent water from flowing to other areas.

[0106] The structure related to the top of powder bowl 43 is as follows: First, a first connecting part 431 is provided on the outside of the top of powder bowl 43, and first connecting part 431 is located between pressing part 411 and the top of powder pot outer bowl 42. A connecting groove 4311 is formed at the bottom of first connecting part 431 to correspond to the top of powder pot outer bowl 42. In actual use, the pressing part 411 and the top of powder pot outer bowl 42 press first connecting part 431 to connect and limit the position of powder bowl 43. Second, to make the connection more stable, a connecting groove 4311 is further formed at the bottom of first connecting part 431, which engages with the top of powder pot outer bowl 42.

[0107] Furthermore, compared to a plate-shaped filter, powder bowl 43 is easier to install, and if the orientation is correctly adjusted, powder can be directly poured into the powder pot without tilting, and powder bowl 43 itself is less likely to move within powder pot outer bowl 42. Furthermore, because powder bowl 43 is made of metal, contact between water and plastic components can be significantly reduced compared to a plate-shaped filter.

[0108] Next, in order to mount powder bowl 43 more stably, second elastic member 47 is provided, and its specific structure is as follows: As shown in Figures 3 to 5, first, water inlet seat 41 includes a second body and a pressing part 411 located on the top outer side of the second body. Second elastic member 47 is provided on the inner wall of outer bowl 42 of the powder pot. At least one protrusion 471 is provided on the inner wall of second elastic member 47. Protrusion 471 is fitted on the outside of the second body and abuts against powder bowl 43.

[0109] Therefore, in actual use, the protrusion 471 is fitted onto the outside of the second body and abuts against the powder bowl 43, so that the powder bowl 43 is more stably attached.

[0110] Here, second elastic member 47 is attached as follows: a groove is formed on the inner wall of outer bowl 42 of the powder pot to accommodate second elastic member 47. Second seal ring 34 is further provided on the outside of the second body, and protrusions 471 and second seal ring 34 are located on both sides of the side wall of powder bowl 43. Protrusions 471 and second seal ring 34 are engaged with powder bowl 43, making powder bowl 43 more stable.

[0111] It should be noted that the method of stably mounting the powder bowl 43 in the powder pot outer bowl 42 by the second elastic member 47 is a removable assembly method, and in addition to this method, the powder bowl 43 can also be fixed to the powder pot outer bowl 42 by other methods such as welding, interference fitting, etc.

[0112] 3 to 5, the mounting structure of the first seal ring 31 is as follows: First, a first liquid outlet 421 is formed at the bottom of the outer bowl 42 of the powder pot, and a first mounting groove 422 is formed on the inner bottom surface of the outer bowl 42 of the powder pot outside the first liquid outlet 421, and the first seal ring 31 is positioned in the first mounting groove 422.

[0113] The structure of first seal ring 31 itself is as follows: First seal ring 31 includes first body 311 and first protrusion 312 provided on the top of first body 311. First protrusion 312 is located outside the plurality of filter holes and contacts the bottom of powder bowl 43. Both the inner and outer sides of first protrusion 312 are inclined surfaces that slope toward first liquid outlet 421.

[0114] Therefore, in actual use, the bottom of the powder bowl 43 generally does not come into direct and complete contact with the inner bottom surface of the powder pot outer bowl 42. The first protrusion 312 is arranged to conveniently fill this gap, and is also arranged at an angle toward the first liquid outlet 421, thereby increasing the contact area between the liquid and the first sealing ring 31 and further providing a buffering effect.

[0115] In addition, to save costs, the upper and lower dimensions of the first body 411 may be different. In this case, the outer side of the upper part of the first body 311 must abut against the inner wall of the first mounting groove 422, and the lower dimension must be smaller than the upper dimension.

[0116] As shown in Figures 3 to 9, hot water flows out from the mounting frame 1 through the water inlet seat 41, the powder bowl 43, the powder pot outer bowl 42, and the base 45. A structure for controlling the flow of liquid is provided between the powder pot outer bowl 42 and the base 45, which effectively prevents the coffee remaining in the powder pot outer bowl 42 from seeping out, prevents the exterior from getting dirty, and makes cleaning and maintenance easier.

[0117] The specific structure is as follows: First, a first liquid outlet 421 is formed at the bottom of the powder pot outer bowl 42, a second liquid outlet 451 is formed at the bottom of the base 45 corresponding to the first liquid outlet 421, a first elastic member 461 is provided between the powder pot outer bowl 42 and the base 45, and a first closure 462 is provided on the first elastic member 461 corresponding to the first liquid outlet 421.

[0118] Therefore, during actual use, the top of the first closer 462 is positioned within the first liquid outlet 421 due to the action of the first elastic member 461, so that the first liquid outlet 421 and the second liquid outlet 451 are not connected, and when water applies force to the first closer 462 and moves the first closer 462 downward, the first liquid outlet 421 and the second liquid outlet 451 become connected.

[0119] The structure of the first elastic member 461 is as follows: a bottom cover 463 is provided between the outer bowl 42 of the powder pot and the base 45, and an outlet 4632 is formed on the bottom cover 463 in correspondence with the first liquid outlet 421. The first elastic member 461 is located between the bottom cover 463 and the outer bowl 42 of the powder pot, and the movement of the first closer 462 controls the communication between the first liquid outlet 421 and the outlet 4632.

[0120] This is because, in actual use, when a capsule is placed after removing powder pot outer bowl 42 and powder bowl 43, break-through plate 49 is provided on base 45, and breaks through the capsule. Therefore, to prevent the first elastic member 461 from affecting break-through plate 49, a bottom cover 463 is provided to separate first elastic member 461 and break-through plate 49.

[0121] In addition, at least two positioning grooves 4631 are opened in the bottom cover 463, and the first elastic member 461 includes a second connection portion 4611 and an elastic piece 4612 located outside the second connection portion 4611, and the second connection portion 4611 has a first closure 462 corresponding to the first liquid outlet 421, and the elastic piece 4612 is inclined, and its end away from the second connection portion 4611 is located in the positioning groove 4631.

[0122] Therefore, in actual use, the end of the elastic piece 4612 far from the second connection portion 4611 is positioned within the positioning groove 4631 to limit relative rotation and make the installation more stable, so that four elastic pieces 4612 may be provided.

[0123] The structure between the first closer 462 and the second connecting part 4611 is as follows: First, a fastening block 4621 is provided at the bottom of the first closer 462, a corresponding hole is opened in the second connecting part 4611, and a second sealing member 32 is provided on the outside of the bottom cover 463. Here, the bottom surface of the second sealing member 32 is formed as a stepped surface, which increases the contact area with the push-break plate 49 and prevents water from flowing to other parts.

[0124] As shown in Figures 8 and 9, the structure related to water inlet seat 41 is as follows: First, water inlet seat 41 has water inlet 412 for circulating water, and water inlet seat 41 is provided with water inlet mesh 481 and drainage mesh 482 on both the top and bottom of water inlet 412, with the holes on water inlet mesh 481 and drainage mesh 482 having a diameter of approximately 0.3 mm. In actual use, water inlet mesh 481 and drainage mesh 482 serve to separate the water into multiple channels and also to block coffee grounds and liquid that may splash out during brewing.

[0125] Here, the water inlet mesh 481 is installed as follows: First, a receiving groove 413 is formed in the water inlet seat 41, a first bump 4131 is provided in the receiving groove 413, the water inlet mesh 481 is placed in the receiving groove 413, and a third locking groove 4811 is opened corresponding to the first bump 4131. The drainage mesh 482 is installed as follows: First, a second bump 414 is formed on the bottom of the water inlet seat 41, and a locking hole 4821 is opened in the drainage mesh 482 corresponding to the second bump 414. A support column 415 is further provided on one side of the drainage mesh 482 at the bottom of the water inlet seat 41, which provides support for the drainage mesh 482.

[0126] To make the connection more stable, the connection may be fastened with screws or the like.

[0127] To facilitate the extraction, several additional structures are added during the coffee pouring process. First, the present invention further includes a powder receiving ring 50 that is fastened to the edge of the powder bowl 43. When ground coffee powder needs to be poured into the powder bowl 43, the powder receiving ring 50 is simply attached to the powder bowl 43. Because coffee powder is loose, pouring more than 10g of coffee powder directly into the powder bowl 43 will inevitably spill out. However, the powder receiving ring 43 increases the space for the coffee powder, making it easier to pour a single dose of coffee powder into the powder bowl 43. Then, the powder bowl 43 is shaken on the table and the coffee powder is pressed with a powder press, making it easier to pour all of the coffee powder into the powder bowl 43.

[0128] The structure between powder receiving ring 50 and powder bowl 43 is as follows: powder receiving ring 50 includes a contact portion 501 and a second mounting portion 502 disposed on the outside of contact portion 501. A third bump 503 is disposed on the inside of second mounting portion 502, and the side wall located outside connecting groove 4311 of first connecting portion 431 is the side edge. In actual use, the bottom of contact portion 501 contacts the top surface of first connecting portion 431, and the top surface of third bump 503 engages with the bottom of the side edge, thereby achieving attachment of powder receiving ring 50.

[0129] The present invention further includes a folding spoon 60, one of whose functions is to receive coffee beans or coffee powder and another function is to act as a powder presser. The specific structure is as follows: First, the folding spoon 60 includes a spoon body 601 and a spoon handle 602 rotatably mounted on the spoon body 601. The spoon body 601 is positioned in the powder bowl 43 and can be used to press the coffee powder therein.

[0130] The folding spoon 60 can be locked when opened, and the specific structure is as follows: the end of the spoon handle 602 rotatably connected to the spoon body 601 adopts a shaft hole rotation structure, and a second protrusion 605 is provided on the outside of this end, and a fifth locking groove 606 is opened on the spoon body 601 corresponding to the second protrusion 605. Therefore, during actual use, the second protrusion 605 and the fifth locking groove 606 are fitted together, thereby restricting the rotation of the spoon handle 602 after opening.

[0131] The folding spoon 60 has a position restriction structure after folding as follows: First, a third protrusion 603 is provided on the inside of one end of the spoon handle 602, and a second locking groove 604 is opened in the spoon body 601 corresponding to the third protrusion 603. Therefore, during actual use, the third protrusion 603 and the second locking groove 604 fit together to restrict the rotation of the spoon handle 602 after folding.

[0132] Next, the folding spoon 60 occupies a small space after folding and can be placed almost completely inside the powder bowl 43. As shown in Figure 12, the folding spoon 60, powder receiving ring 50, and powder pot outer bowl 42 can be stacked to reduce the space required, making them easier to carry and pack when users go out. The folding spoon 60 and powder receiving ring 50 can also be placed inside the heated water tank body 82, reducing the space required, making them easier to carry and pack when users go out.

[0133] As shown in Figures 10 and 11, the extraction assembly is of the second structure, and the difference between the second structure and the first structure lies in the structure, position, and assembly relationship of the closure. The closure structure in the second structure employs a second closure 464, which is located in the base 45. In this case, the powder pot outer bowl 42 does not have a first closure 462, a first elastic member 461, and a bottom cover 463.

[0134] Specifically, second closure 464 is built into second liquid outlet 451 on base 45, and second closure 464 has first gap 4641 formed therein, which is in a closed state and opens when force is applied. Therefore, when not in use, first gap 4641 is in a closed state, and when it comes into contact with hot water, it opens when force is applied.

[0135] The second closer 464 has the following structure: First, a second groove 4642 communicating with the first gap 4641 is formed at the top of the second closer 464, thereby reducing the thickness of that portion of the first gap 4641 and making it easier to open the first gap 4641. An assembly part 4643 is provided on the periphery of the second closer 464, and an assembly groove is formed in the base 45 corresponding to the assembly part 4643, so that installation is achieved by fitting the assembly part 4643 into the assembly groove.

[0136] Next, a third seal 33 is provided on the outside of the bottom of the powder pot outer bowl 42. The bottom surface of the third seal 33 is stepped, increasing the contact area with the break-through plate 49 and preventing water from flowing to other locations. Specifically, the third seal 33 and the powder pot outer bowl 42 are removably and fixedly connected. As can be seen in FIG. 10, a ring-shaped locking shackle is formed on the bottom of the powder pot outer bowl 42, and a second position-limiting groove is formed on the surface of the third seal 33 to engage with the locking shackle. Therefore, during assembly, it is only necessary to engage the second position-limiting groove on the third seal 33 with the locking shackle, making it easy to install or replace the third seal 33.

[0137] As shown in Figure 23, the structure between the mounting frame 1 and the water inlet seat 41 is as follows: First, a first passage 11 for circulating water is opened in the mounting frame 1, a water inlet port 412 is opened in the water inlet seat 41, and a first seal member 35 is provided on the side of the mounting frame 1 closest to the water inlet seat 41.

[0138] The mounting frame 1 has a first mounting hole 12, and the mounting frame 1 has an engagement groove 13 formed on the outside of the first passage 11. The first seal member 35 has a first engagement block 351 provided in correspondence with the first mounting hole 12, a first engagement portion 352 provided in correspondence with the engagement groove 13, and a first through-hole 353 provided in correspondence with the first passage 11. Next, the bottom of the first seal member 35 is provided with a sealing surface that abuts against the water inlet seat 41 and is positioned outside the water inlet 412 to prevent water from flowing outward.

[0139] Therefore, while in actual use, a single seal is provided for both the first mounting hole 12 and the first passage 11, the present invention uses a single first seal 35 to seal two locations, thereby realizing multi-purpose use of a single member, thus simplifying the structure and making installation easier. Furthermore, to avoid interference with the first seal 35, a first groove 416 is provided in the water inlet seat 41.

[0140] As shown in Figures 24, 28, and 29, the heating area is structured as follows. First, the heating area includes a heated water tank body 82 and a lid 7. The lid 7 includes an outer lid 71 and an inner lid 72 attached to the bottom opening of the outer lid 71. A fourth seal member 73 is attached between the outer lid 71 and the inner lid 72. A hole is formed in the inner lid 72 to expose the fourth seal member 73. A second gap 731 is formed in the exposed portion of the fourth seal member 73, and the second gap 731 opens when a force is applied. At least one first vent hole 711 is formed in the top of the outer lid 71, and the first vent hole 711 communicates with the inside of the fourth seal member 73.

[0141] Therefore, in actual use, the second gap 731 is provided, which closes when not in use, and the closed second gap 731 can prevent water vapor from leaking out. When ventilation is required, the second gap 731 opens under force, and the first ventilation hole 711 communicates with the inside of the fourth sealing member 73, creating a passage for air to circulate. Compared to relying solely on gaps, the present invention has higher fluidity and better exhaust effect, does not require a guide column, and simplifies the structure.

[0142] The shape of second gap 731 itself is as follows: First, the cross section of second gap 731 is V-shaped, and the V-shaped opening is provided on the side of fourth seal member 73 closer to heated water tank body 82; that is, the upper part is smaller and the lower part is larger. The purpose of making the lower part larger here is to make it easier for gas to enter, and the purpose of making the upper part smaller is to reduce gas emissions as much as possible when closed.

[0143] 24, 25, and 29, a flow dividing and flow restricting structure is further provided within the air passage, and the flow dividing structure is as follows: First, at least two second protruding plates 712 are provided on the inside of outer cover 71, and a flow dividing port 713 is provided between two adjacent second protruding plates 712. Therefore, during actual use, the provision of flow dividing port 713 allows gas to be diverted near first air vent 711, making it easier to discharge the gas.

[0144] The flow restriction structure is as follows: First, a second baffle 714 is provided inside the outer cover 71, with the top of the second baffle 714 located outside the first vent hole 711 and the bottom of the second baffle 714 abutting against the fourth seal member 73. In actual use, the second baffle 714 is multi-purpose, and its top is located outside the first vent hole 711, restricting gas from flowing beyond the first vent hole 711. At the same time, the bottom of the second baffle 714 abuts against the seal member 73, pressing against the seal member 73 and ensuring the stable installation of the seal member 73.

[0145] 28, the mounting structure of the fourth seal member 73 is as follows: First, the fourth seal member 73 includes an exposed portion 732 and a third connecting portion 733 located outside the exposed portion 732. A second gap 731 is formed in the exposed portion 732. A hole is formed in the inner lid 72 to expose the exposed portion 732. A second mounting groove 721 is formed on the inside of the inner lid 72 for disposing the third connecting portion 733. Therefore, in actual use, the seal member 73 is first disposed inside the inner lid 72. At this time, the third connecting portion 733 is located in the second mounting groove 721, and the exposed portion 732 is exposed through the opening in the inner lid 72.

[0146] The bottom of the second baffle 714 abuts against the third connecting portion 733 and fits into the second mounting groove 721 to press and restrict the third connecting portion 733, thereby ensuring stability of the installation. To further stabilize the installation, a first protrusion 722 is provided in the second mounting groove 721, and the first protrusion 722 and the fourth seal member 73 are tightly fitted together. In addition to this sealing, the heated water tank body 82 and the lid 7 are also provided with a seal member 6 to prevent gas from flowing in other directions.

[0147] Next, the outer cover 71 and the inner cover 72 are connected by a snap fit, i.e., a locking member 715 is provided on the inner wall of the outer cover 71, and a third locking groove 723 is provided on the outside of the inner cover 72 corresponding to the locking member 715. Compared with conventional screw connections, installation using a snap fit connection is easier and more convenient.

[0148] As shown in Figure 32, a heating plate 81 is installed on the bottom or side wall of the heated water tank body 82. A common design is a ceramic heating piece fixed with adhesive. This heating method has low thermal efficiency, slow and uneven heat transfer, and the ceramic pieces are prone to shattering. For this reason, the heating plate 81 of the present invention is made of metal and has a printed heating element. The heating element uses a heating wire 811, and tangential elements 812 are attached to both ends of the heating wire 811. The heated water tank body 82 and the heating plate 81 are welded together. This is because metals such as aluminum plates have high conductivity, are strong and durable, and the printed heating wire 811 is not easily burned by large currents, resulting in a longer service life and less damage.

[0149] Here, the coverage and path of the heating wire 811 are not specifically limited and can be set as needed. The tangent body 812 can be installed in the form of a land tangent, a tangent column, or even an elastic strip contact. The heating plate 81 is also provided with a thermistor 813. In a typical design, the thermistor 813 is attached with aluminum foil, which causes delays and inaccuracies in temperature control. Therefore, the thermistor 813 of the present invention is directly welded to the heating plate 81, which allows for more real-time and accurate temperature control.

[0150] As shown in Figures 30 and 31, the mounting structure of the heated water tank body 82 in the conventional structure is that claws extend from the assembly frame 9 and engage with the edge of the support ring located below the heated water tank body 82. Therefore, a support ring is added here, and the third circuit board 30 is directly installed on the top of the assembly frame 9 and located directly below the heated water tank body 82, so that the heat generated during heating affects the third circuit board 30.

[0151] In contrast, the present invention adopts a different structure. First, an assembly frame 9 is installed inside the machine body 20, and includes a bracket 91 and a first mounting plate 92 attached to the bracket 91. A third circuit board 30 is installed between the bracket 91 and the first mounting plate 92. Therefore, during actual use, the presence of a first mounting plate 92 above the third circuit board 30 can insulate against heat and further protect the third circuit board 30.

[0152] Furthermore, the first mounting plate 92 is provided with at least two insertion holes 93, the inner walls of the insertion holes 93 are provided with fourth protrusions 94, and the heated water tank body 82 is provided with at least two first connecting plates 821 on the outside, the bottoms of the first connecting plates 821 being located within the insertion holes 93 and the engaging holes 822 being opened corresponding to the fourth protrusions 94. Therefore, during actual use, the bottoms of the first connecting plates 821 are located within the insertion holes 93 and the fourth protrusions 94 are fitted into the engaging holes 822, thereby mounting the heated water tank body 82 on the first mounting plate 92. Furthermore, compared to claws, molding the plate members and protrusions is easier, and the structure is simplified because there is no support ring structure.

[0153] To ensure a more stable installation and prevent the heating plate 81 located at the bottom from sticking to other components, the first mounting plate 92 is provided with at least one support block 95, which includes a side plate 96 and a pad 97 provided on one side of the side plate 96. In actual use, the pad 97 is located at the bottom of the heated water tank body 82 to prevent the heating plate 81 from sticking to other components, and the side plate 96 is attached to the outside of the heated water tank body 82 to prevent the heated water tank body 82 from tilting. In addition to being located at the bottom of the heated water tank body 82, the heating plate 81 may also be located on the outer wall of the heated water tank body 82, in which case the heating plate 81 engages with the side plate 96.

[0154] 24 to 27, the motor and heating plate 81 generate heat during operation and also generate heat during charging, so a ventilation structure is required, but a waterproof structure is also required to prevent water from getting in. Since the charging assembly 5 and key assembly 6 are close to the heat generation points, it is more appropriate to install the heater on the charging assembly 5 and key assembly 6, but since it is difficult to drill holes in the key assembly 6, it is installed on the charging assembly 5.

[0155] The specific structure is as follows: As shown in Fig. 25, a charging assembly 5 is provided on one side of the machine body 20, and the charging assembly is located on one side of the heating area and includes a first circuit board 51, a mounting member 52, and a silica gel cover 53. The mounting member 52 is provided on the machine body 20, and the first circuit board 51 and the silica gel cover 53 are respectively connected to the inner and outer sides of the mounting member 52.

[0156] Furthermore, a charging connector 54 is provided on the first circuit board 51, and a hole is formed in the mounting member 52 to expose the charging connector 54. The mounting member 52 has a second ventilation hole 55 on one side of the charging connector 54, and a waterproof, breathable film 56 is provided on the inside of the mounting member 52 in correspondence with the second ventilation hole 55. Therefore, during actual use, the charging assembly 5 is located on one side of the heating area and the waterproof, breathable film 56 is provided, so that heat generated by the heating area and the charging assembly 5 is discharged and ventilated through the waterproof, breathable film 56, further preventing water from being introduced into the machine body 20. Furthermore, because the charging assembly 5 is located on one side of the machine body 20, heat generated within the machine body 20, such as heat from the motor, is also discharged through the waterproof, breathable member.

[0157] Here, the charging connector 54 may use a Type-C interface, and the waterproof and breathable film 56 is a novel polymer waterproof material with a conventional structure. The principle is as follows: the distance between gas molecules is large, allowing them to penetrate the pores of the waterproof and breathable film 56 during diffusion. The distance between liquid molecules is smaller than the pore distance, and the liquid molecules cannot penetrate the waterproof and breathable film 56 due to the effect of surface tension, thus achieving a waterproof function.

[0158] The specific structure of the charging assembly 5 is as follows: First, a first tangent terminal 57 is provided on the first circuit board 51, and a second tangent terminal 301 is provided on the third circuit board 30, and the first tangent terminal 57 and the second tangent terminal 301 are connected by an electric wire.

[0159] Here, third circuit board 30 is the main circuit board for controlling the operation of each component of the coffee machine, and first junction terminal 57 and second junction terminal 301 are connected by electric wires to achieve electrical connection between third circuit board 30 and first circuit board 51. Therefore, compared to conventional coffee machines which only have one main circuit board, first circuit board 51 has an independent structure from third circuit board 30, and as such, first circuit board 51 is positioned closer to the sealing ring and waterproof / breathable film 56, thereby achieving better ventilation and waterproofing.

[0160] Next, the structure related to the silica gel cover 53 is as follows: First, the silica gel cover 53 is provided with a plug ring 531 corresponding to the charging connector 54, and the installation of the plug ring 531 serves to seal and waterproof the cover.

[0161] An attachment column 532 is provided inside the silica gel cover 53, and a connection hole 521 is provided in the attachment member 52 corresponding to the attachment column 532. A second stopper 533 is provided on the outer side of the end of the attachment column 532 that passes through the connection hole 521, and the length and width of the second stopper 533 are greater than the length and width of the connection hole 521. Therefore, in actual use, the attachment column 532 passes through the connection hole 521 to connect the silica gel cover 53 and the attachment member 52, and the second stopper 533 abuts against the inside of the attachment member 52 to prevent the attachment column 532 from coming off the connection hole.

[0162] The structure related to the mounting member 52 is as follows: First, a second mounting hole for disposing the charging assembly 5 is formed in the machine body 20, a seal ring 7 is provided between the inner wall of the second mounting hole and the outside of the mounting member 52, a third ridge is provided on the inner wall of the second mounting hole, a locking plate 523 is provided on the inside of the mounting member 52, a third locking block 524 is provided on the outside of the locking plate 523, and the side of the third locking block 524 closest to the mounting member 52 abuts against the third ridge. Therefore, in actual use, the installation of the seal ring plays a role in sealing and waterproofing, improving the waterproof level, and the machine body 20 and the mounting member 52 are connected when the third locking block 5245 abuts against the third ridge.

[0163] The connection structure between the mounting member 52 and the first circuit board 51 is as follows: First, a hollow mounting column 522 is provided inside the mounting member 52, and holes 512 are opened in the first circuit board 51 corresponding to the mounting column. Fastening members pass through the holes 512 and enter the mounting column 522, thereby connecting the mounting member 52 and the first circuit board 51. Here, the fastening members are screws.

[0164] Furthermore, before connecting with fastening members, initial positioning is required, and the structure is as follows: First, a column 525 is provided on the mounting member 52, and an assembly hole 511 is provided in the first circuit board 51 corresponding to the column. Therefore, in actual use, the column 525 and the assembly hole 511 are fitted together to achieve connection, and before connecting with fastening members, the mounting column 522 and the hole 512 are initially positioned and aligned.

[0165] 26, to improve the sealing and waterproofing effect, the structure of the key assembly 6 is further optimized, and the specific structure is as follows: First, the key assembly 6 is installed on the other side of the machine body 20, and the machine body 20 is installed with a second circuit board 40 inside the key assembly 6, which includes a first light-transmitting member 61 and a pressing plate 62 installed on the first light-transmitting member 61, and a button 401 is installed on the second circuit board 40 corresponding to the pressing plate 62, and the first light-transmitting member 61 is elastic and is secondarily injection molded with the machine body 20.

[0166] Therefore, during actual use, as a result of secondary injection molding of the first light-transmitting member 61 and the machine body 20, the first light-transmitting member 61 and the machine body 20 form an integral structure with essentially no seams or gaps. Compared to conventional coffee machines, in which the key and the machine body are separate structures assembled by methods such as adhesive injection or snap fitting, the sealing and waterproof effect achieved by secondary injection molding is higher, and the waterproof level is higher than that of conventional coffee machines.

[0167] Here, secondary injection molding is a process in which a plastic raw material is molded into a primary plastic mold, the molded part is then removed, placed into a secondary mold, and the same or a different type of plastic material is injected again to mold the part.

[0168] In addition, since the button 401 is generally combined with an indicator lamp, an illuminant 402 is provided on the second circuit board 40, and in order to further enhance the sealing and waterproof effect, a second light-transmitting member 63 is provided on the machine body 20 corresponding to the illuminant 402, and the second light-transmitting member 63 and the machine body 20 are secondary injection molded.

[0169] As shown in Figures 26 and 27, the specific structure of the key assembly 6 further includes a decorative ring 64 provided on the outside of the first light-transmitting member 61. The structure between the decorative ring 64 and the first light-transmitting member 61 is as follows: First, a protruding ring 611 is provided on the first light-transmitting member 61, and a first protruding plate 612 is provided on the outside of the protruding ring 611. The decorative ring 64 is fitted on the outside of the protruding ring 611, and the first protruding plate 612 is located between the decorative ring 64 and the machine body 20.

[0170] The structure between the decorative ring 64 and the machine body 20 is as follows: First, the machine body 20 has a third adhesive groove on the outer side of the first light-transmitting member 61, and the inner side of the decorative ring 64 is located within the third adhesive groove.

[0171] Next, the structure between the pressure plate 62 and the first light transmitting member 61 is as follows: First, a protruding ring 611 is provided on the first light transmitting member 61, and the first light transmitting member 61 has a first mounting portion 613 provided within the protruding ring 611. A third mounting groove 621 is opened on the inside of the pressure plate 62 corresponding to the first mounting portion 613, a first adhesive groove 614 is opened at the top of the first mounting portion 613, and a second adhesive groove 615 is formed between the inner wall of the protruding ring 611 and the outer wall of the first mounting portion 613.

[0172] Therefore, in actual use, the pressure plate 62 is fitted and then fixed with adhesive, and the fitting structure is such that the first mounting portion 613 fits into the third mounting groove 621, and the upper and lower diameters of the first mounting portion 613 can be different, thereby limiting the placement position of the pressure plate 62. In addition, the first adhesive groove 614 and the second adhesive groove 615 are provided, which realizes two-point attachment and further stably attaches the pressure plate 62.

[0173] The above has shown and described the basic principles, main features and advantages of the present invention, and the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the principles and scope of the present invention, and all such changes and modifications are within the scope of the present utility model registration claims.
