[0075] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0076] like Figures 1-2 As shown, the coffee machine includes a cup body 200, with a heating zone at one end and an extraction zone at the other end. An outer cup 300 is also provided outside the extraction zone to hold the extracted coffee. A sealing structure exists between the extraction zone and the cup body 200. To improve the sealing effect and facilitate installation, a water circuit structure for the coffee machine is designed, as follows: Figures 2-4 As shown, it includes a mounting bracket 8 and a sealing element 9 disposed at the bottom of the mounting bracket 8. The mounting bracket 8 has a water supply channel 81 and a mounting hole 83. The mounting bracket 8 also has a snap-fit ​​groove 84 on the outside of the channel 81. The mounting hole 83 is used to assemble the mounting bracket 8 onto the cup body 200 by means of screws or ultrasonic welding.

[0077] Meanwhile, the sealing element 9 is used to seal between the mounting frame 8 and the extraction zone, and the sealing element 9 has a through hole 93 corresponding to the channel 81, and the sealing element 9 has a locking block 91 corresponding to the mounting hole 83, and the sealing element 9 has a locking part 92 corresponding to the locking groove 84.

[0078] Therefore, in actual use, a single sealing element 9 simultaneously seals the mounting bracket 8 and the extraction zone, as well as the mounting hole 83, achieving multiple functions with a single component and making installation more convenient. Furthermore, the sealing element 9 and the mounting bracket 8 have multiple connections, making it less prone to falling off.

[0079] Furthermore, in order to increase the outlet diameter, the mounting bracket 8 has at least one overflow trough 82 that communicates with the channel 81. Therefore, in actual use, the overflow trough 82 increases the outlet diameter, resulting in faster water output and better compatibility with the extraction zone.

[0080] The utility model discloses still protect a kind of coffee machine, it includes cup body 200, and cup body 200 one end is provided with heating area, and cup body 200 other end is provided with extraction area, and extraction area and cup body 200 between being provided with the waterway structure of any one described above, while extraction area includes mounting seat 3 and upper cover 2, and mounting seat 3 and upper cover 2 between are detachably connected, and mounting seat 3 is formed with the placing cavity for placing capsule or coffee powder on it.

[0081] Wherein the structure between upper cover 2 and waterway structure is: first mounting frame 8 is set to cup body 200 one end, and sealing piece one 9 is located between mounting frame 8 and upper cover 2. While upper cover 2 top is provided with recess 22, and recess 22 is provided with several water inlet holes 23 for water flow, and sealing piece one 9 bottom is provided with sealing surface, and sealing surface and recess 22 bottom surface abut and are located outside water inlet hole 23 to avoid water flowing outward. Thus in actual use process, by the setting of recess 22 to avoid interference with other components, compared with plane, the setting of recess 22 can also limit the water to a certain extent, avoid flowing to other orientation. And sealing surface and recess 22 bottom surface abut and are located outside water inlet hole 23 to avoid water flowing outward.

[0082] While the structure between mounting seat 3 and upper cover 2 is various, such as adapting movable puncture needle 10, such as adapting extraction bin 6, or adapting the combination of burst plate 80 and puncture needle 10.

[0083] First, when mounting seat 3 and upper cover 2 adapt the combination of burst plate 80 and puncture needle 10, as shown in Figures 15-17 , first, upper cover 2 bottom is set in mounting seat 3, and upper cover 2 is built-in puncture needle 10, and mounting seat 3 is provided with burst plate 80 below upper cover 2.

[0084] While mounting seat 3 inner wall is provided with limit block one, and the upper surface of limit block one is wavy, and upper cover 2 bottom outside is provided with limit slot corresponding to limit block one.

[0085] Thus in actual use process, by the adaptation of limit block one and limit slot to limit the mutual rotation between mounting seat 3 and upper cover 2.

[0086] Second, when mounting seat 3 and upper cover 2 adapt movable puncture needle 10, as shown in Figures 5-9 , mounting plate one 4 is provided between upper cover 2 and mounting seat 3, and puncture needle 10 is provided between upper cover 2 and mounting plate one 4, and upper cover 2 is provided with several water inlet holes 23.

[0087] Meanwhile, the mounting plate 14 has a cavity below the water inlet hole 23, and a channel 2 41 communicating with it is provided in the cavity. The bottom of the puncture needle 10 is moved and installed in the channel 2 41, and the top of the puncture needle 10 passes through the upper cover 2 and protrudes. A channel 3 101 for water supply is provided in the middle of the puncture needle 10, and a side opening 102 is provided on the side wall of the puncture needle 10. The side opening 102 is used to connect the cavity and the channel 3 101.

[0088] Therefore, in actual use, when water flows to the mounting plate 4, it can enter the channel 101 from the side opening 102 and then flow into the capsule 90, thus greatly reducing the situation of water stagnating on the mounting plate 4.

[0089] The number of side openings 102 can be selected according to the actual situation. For example, both sides of the puncture needle 10 are provided with side openings 102 that communicate with the channel 3 101, and the two side openings 102 are symmetrically arranged. Moreover, the top of the puncture needle 10 passes through the upper cover 2 and is exposed by passing through the through hole 3 of the upper cover 2.

[0090] Furthermore, to prevent excessive water inflow, channel 2 41 is designed to be formed by at least two protruding plates 42, with gaps between adjacent protruding plates 42. Therefore, in actual use, the protruding plates 42 and the gaps achieve water diversion. The number of protruding plates 42 can be selected according to actual conditions; for example, mounting plate 4 may have four protruding plates 42 on the outside of channel 2 41.

[0091] Meanwhile, corresponding to the channel 81 above, the diameter of the puncture needle 10 is larger than the aperture of the channel 81, and the channel 81 and the overflow groove 82 form a cross-shaped water outlet structure. Moreover, the shape of this water outlet structure is different from that of the puncture needle 10. In this way, when the assembly is completed and the top cover 3 is installed on the mounting bracket 8, the puncture needle 10 is subjected to force and moves downward, so that the tip of the puncture needle 10 initially punctures the surface of the capsule 90, thereby facilitating subsequent extraction.

[0092] After extraction is complete, the top cover 3 and other structures can be removed from the mounting bracket 8. At this time, the puncture needle 10 will automatically retract after losing the pushing force. The position of the puncture needle 10 after restoration is important. If it is not fully restored to the inside, it will be exposed and cause scratches to the user.

[0093] Therefore, as Figure 6 As shown, mounting plate 4 has a boss 43 below channel 2 41, and the boss 43 has a through hole 2 44 communicating with channel 2 41. A spring 100 is provided between the boss 43 and the puncture needle 10, and the bottom of the puncture needle 10 is located in the through hole 2 44 under the action of the spring 100.

[0094] Therefore, in actual use, the length of the second channel 41 can be increased by the convex 43, so as to avoid the situation that the reset piercing needle 10 is still exposed after passing through the mounting plate 1, thereby avoiding the piercing needle 10 causing scratches to the user. Moreover, in order to avoid the spring 100 from falling off the second channel 41, the caliber size of the through hole 44 is designed to be smaller than the caliber size of the second channel 41.

[0095] Meanwhile, the piercing needle 10 is provided with a limiting plate 103 outside, and the spring 100 is located between the bottom of the limiting plate 103 and the convex 43, and the top of the limiting plate 103 can abut against the upper cover 2 to limit the movement range of the piercing needle 10. Therefore, in actual use, the limiting plate 103 can realize one thing with multiple uses, that is, it can limit and press the spring 100, and also limit the movement range of the piercing needle 10.

[0096] Secondly, the sealing ring is arranged between the inner wall of the upper cover 2 and the outer wall of the mounting plate 1, and the upper cover 2 and the mounting plate 1 are connected by screws. Meanwhile, the upper cover 2 is provided with a baffle 26, and the mounting plate 1 is provided with a support plate 45, and the inner wall of the support plate 45 is surrounded to form a cavity, and the support plate 45 is located in the baffle 26 and is provided with a sealing ring between the upper cover 3.

[0097] As shown in Figure 7 and Figure 8 , the inner wall of the upper cover 2 and the outer wall of the mounting plate 3 are detachably connected. Moreover, the detachable connection structure is various, which can be threaded connection or rotating buckle, so the specific structure can be that the inner wall of the upper cover 3 and the outer wall of the mounting plate 3 are connected by threads.

[0098] Alternatively, the inner wall of the upper cover 2 is provided with a sliding groove 24, one side of the sliding groove 24 is opened, and the sliding groove 24 is provided with a clamping groove 241, and the outer wall of the mounting plate 3 is provided with a sliding block 31. Therefore, in actual use, the sliding block 31 enters the sliding groove 24 from the opening and moves in the sliding groove 24, and the sliding block 31 is provided with a convex 311 corresponding to the clamping groove 241, which is limited by the matching of the clamping groove 241 and the convex 311, and when disassembling, a larger force is applied to remove the limit to separate the upper cover 2 and the mounting plate 3.

[0099] Secondly, the capsule 90 that can be placed in the mounting base 3 is a commercially available aluminum capsule, such as DG capsules, Nestlé capsules, or Starbucks capsules. Each capsule has a different internal structure. For example, Nestlé capsules are entirely sealed and contain coffee powder, while DG capsules, compared to Nestlé capsules, have an internal filter structure with filter holes at the bottom. The attached diagram shows the bottom shell of a DG capsule. When a DG capsule is placed in the mounting base 3, after the puncturing needle 10 punctures the top of the capsule 90, the coffee liquid will flow out from the filter holes at the bottom and exit from the outlet of the mounting base 3.

[0100] Meanwhile, other structures are as follows: First, a sealing ring is provided between the outer wall of the capsule 90 and the inner wall of the mounting base 3. Furthermore, a connecting plate 901 is provided on the outer side of the top of the capsule 90, and a step is provided on the inner wall of the top cover 2. The connecting plate 901 is located between the step and the mounting base 3, and the bottom of the mounting plate 4 abuts against the connecting plate 901.

[0101] Then, when the mounting base 3 and the upper cover 2 are compatible, the extraction chamber 6 is used, such as Figures 10-14 As shown, an extraction chamber 6 is provided between the upper cover 2 and the mounting base 3. The upper cover 2 includes a main body and a flange 21 located on the outer side of the top of the main body. The bottom of the main body is located inside the extraction chamber 6, and the bottom of the extraction chamber 6 is located inside the mounting base 3.

[0102] Meanwhile, the top of the extraction chamber 6 is bent outward to form a connecting part 61, and the connecting part 61 is located between the bottom of the flange 21 and the top of the mounting base 3. Furthermore, an elastic member 20 is provided between the outer wall of the extraction chamber 6 and the mounting base 3, and at least one protrusion 201 is provided on the inner wall of the elastic member 20, and the protrusion 201 cooperates with the outer side of the main body to abut against the extraction chamber 6.

[0103] Therefore, in actual use, by positioning the connecting part 61 between the bottom of the flange 21 and the top of the mounting base 3, and combining the protrusion 201 with the outer side of the main body, the side wall of the extraction chamber 6 is squeezed, thereby preventing the extraction chamber 6 from becoming loose. Moreover, the outer side of the main body is in close contact with the side wall of the extraction chamber 6, thus achieving a seal.

[0104] The number of protrusions 201 can be selected according to the actual situation. For example, the inner wall of the elastic element 20 can be provided with three protrusions 201, and the elastic element 20 can be opened. Moreover, the edge of the upper cover 2 that contacts the inner wall of the extraction chamber 6 can be aligned, or it can protrude slightly, as long as it fits the inner wall of the extraction chamber 6.

[0105] Meanwhile, the mounting structure of the elastic member 20 is that a mounting groove 32 is formed in the inner wall of the mounting seat 3 to place the elastic member 20. Moreover, a seal is arranged between the extraction bin 6 and the upper cover 2, and the sealing position is not limited. If the stability of the extraction bin 1 is better, a sealing ring can be arranged between the inner wall of the extraction bin 1 and the upper cover 2, and the protruding part 201 and the sealing ring are located on both sides of the side wall of the extraction bin 6, and the protruding part 201 and the sealing ring are matched to abut against the extraction bin 6.

[0106] Secondly, the extraction bin 6 can be made of metal to reduce the contact of coffee liquid with plastic. Moreover, the volume specifications of the extraction bin 1 can be different, and the extraction bin 6 can be large and small, and the height of the large bin is higher than that of the small bin, so that it can be suitable for coffee powder of different weights. For example, the small bin is suitable for 8-12g powder, and the large bin is suitable for 16g powder.

[0107] Meanwhile, the specific structure of the extraction bin 6 can be various. For example, the extraction bin 6 is a powder bowl with a plurality of liquid outlet holes at the bottom. Moreover, it can be a split structure, that is, it includes a bin body 62 and a receiving plate 63. The split structure is used to ensure the stability of the extraction pressure on the basis of bearing coffee powder, that is, the receiving plate 63 passes through the hole to discharge liquid and release pressure.

[0108] When the extraction bin 1 adopts the powder bowl, the diameter of the liquid outlet hole at the bottom of the powder bowl is about 0.3mm. At this time, the coffee liquid can also be extracted in a gradual pressure relief manner, but this method is more suitable for experienced operators.

[0109] When the extraction bin 1 adopts the split structure, that is, the extraction bin 1 includes a bin body 62 and a receiving plate 63 arranged in the bin body 62, and the receiving plate 63 is used to place coffee powder and is provided with a plurality of holes to pass water, and the bin body 62 is provided with a liquid outlet 621 at the bottom.

[0110] The receiving plate 63 is provided with a placing groove 631 to place coffee powder, and the diameters of the holes and the liquid outlet 621 are about 0.3mm. Under this diameter range, when hot water with water pressure enters the extraction bin 6 from the upper cover 2, the hot water will press the coffee powder to achieve pressure extraction, and the pressure is relatively stable during the process, so it is more suitable for beginners.

[0111] Moreover, the connection structure between the receiving plate 63 and the bin body 62 is that the outer side wall of the receiving plate 63 is welded with the inner side wall of the extraction bin 1.

[0112] Meanwhile, the mounting structure of the receiving plate 63 can be optimized, that is, a soft rubber ring 64 is arranged between the receiving plate 63 and the bin body 62, the soft rubber ring 64 is provided with a connecting groove 641 to place the bottom of the receiving plate 63, and a limiting plate two 632 is arranged at the top outer side of the receiving plate 63, and the bottom of the limiting plate two 632 abuts against the top of the soft rubber ring 64.

[0113] Therefore, in actual use, the soft rubber ring 64 ensures that the connection of the receiving plate 63 is not welded, making it detachable and easy to clean. Furthermore, to facilitate the removal of the receiving plate 63 and the soft rubber ring 64, an opening can be made in the limiting plate 632.

[0114] Furthermore, the structure of the soft rubber ring 64 can be optimized. Specifically, a soft rubber ring 64 is provided between the receiving plate 63 and the chamber 62, and the soft rubber ring 64 has a connecting groove 641 for the bottom of the receiving plate 63 to be placed. The top of the soft rubber ring 64 is provided with a second protrusion 642, and a limiting plate 632 is provided on the outer side of the top of the receiving plate 63. The limiting plate 632 is bent into a snap-fit ​​groove 633 corresponding to the second protrusion 642.

[0115] Therefore, in actual use, the matching of the second snap-fit ​​groove 633 and the second protrusion 642 makes the connection between the receiving plate 63 and the soft rubber ring 64 more stable, and the limit plate 632 will have a gap with the inner wall of the chamber 62 after bending, which makes it easy to remove the receiving plate 63 and the soft rubber ring 64.

[0116] like Figures 10-14 As shown, in order to better cooperate with the water circuit of the coffee machine to achieve extraction, a water outlet screen 28 is provided at the bottom of the top cover 2 below the water inlet 23. The pore diameter of the water outlet screen 28 is about 0.3mm, so it can separate multiple water channels and also prevent coffee powder and coffee liquid from splashing during the extraction process. At the same time, the installation structure of the water outlet screen 28 is versatile. It can be placed directly in a groove and secured with screws, or it can be snapped on with a clip 25 and then secured with screws.

[0117] Meanwhile, the structure related to the second card block 25 is as follows: First, the bottom of the upper cover 2 is provided with the second card block 25, and the water outlet net 28 is provided with a card hole 281 corresponding to the second card block 25.

[0118] The second card block 25 and the upper cover 2 are formed in a secondary process, and there are multiple second card blocks. The secondary forming refers to the technology of obtaining the final shape of the product by re-forming the profile obtained by one-time forming of polymer materials such as plates, sheets, rods and tubes under certain conditions.

[0119] Therefore, in actual use, when the water outlet screen 28 is installed on the upper cover 2, the second clip 25 is inserted into the clip hole 281 so that the water outlet screen 28 is in contact with the bottom surface of the upper cover 2. At the same time, in order to make the installation of the water outlet screen 28 more stable, screws are set to tighten it. Moreover, the bottom of the upper cover 2 is provided with a support column 27, which supports the water outlet screen 28. The bottom of the upper cover 2 is flat and flush with the edge, so as to better fit with the water outlet screen 28.

[0120] And the structure that cooperates with the waterway of the coffee machine is optimized, namely the water inlet net 29. The specific structure is that: first, the water inlet net 29 is arranged on the upper side of the water inlet hole 23 of the upper cover 2, or the water inlet net 29 and the water outlet net 28 are arranged on the upper and lower sides of the water inlet hole 23 respectively, and the upper surface of the water inlet net 29 is in the same plane with the bottom surface of the groove 22.

[0121] Therefore, in actual use, since the upper surface of the water inlet net 8 is in the same plane with the bottom surface of the groove 22, the surface is smooth, which is beneficial to the flow of water. At this time, if the water inlet net 29 is used alone on the upper cover 2, the water inlet net 29 plays the role of water inlet and water separation. If the water inlet net 29 and the water outlet net 28 are used simultaneously on the upper cover 2, both of them can play the role of water separation, which is beneficial to the stability of the extraction pressure.

[0122] The water inlet net 29 is made of metal, and the diameter of the holes on the water inlet net 29 is about 0.3mm. When the water inlet net 29 and the water outlet net 28 are used simultaneously on the upper cover 2, the diameters of the holes on the water inlet net 29 and the water outlet net 28 are consistent. Therefore, on the basis of not hindering the flow of hot water, the pressure in the extraction chamber 1 can be prevented from being released too quickly to a certain extent, and the metal water inlet net 29 is easy to clean.

[0123] Meanwhile, the structure between the upper cover 2 and the water inlet net 29 is that: first, the groove 22 is provided with an assembly groove 221, and the inner wall of the assembly groove 221 is provided with a protrusion 222. Therefore, in actual use, the water inlet net 29 is located in the assembly groove 221, and a clamping groove 291 is arranged corresponding to the protrusion 222.

[0124] Meanwhile, in order to make the installation more stable, a connecting column is arranged, which passes through the water inlet net 29, the upper cover 2 and the water outlet net 28, so as to arrange the water inlet net 29 and the water outlet net 28 on the upper cover 2. The connecting column can be two components, such as a bolt and a nut, or a rivet structure.

[0125] As shown in Figure 11 In order to separate the extraction chamber 6 and the upper cover 2, a gap is arranged between the extraction chamber 6 and the upper cover 2, so as to facilitate the fingers or nails to enter.

[0126] The gap can be formed by arranging an abutting block on the bottom of the turning edge 21, and the connecting part 61 is located between the abutting block and the top of the mounting seat 3, so that the mounting seat 3 and the turning edge 21 have a gap.

[0127] Alternatively, the gap can be formed by bending the connecting part 61 to form a protrusion 65, and the protrusion 65 is located between the turning edge 21 and the top of the mounting seat 3, so that the mounting seat 3 and the turning edge 21 have a gap.

[0128] As shown in Figures 23-28 The structure of the heating zone: first, the heating zone comprises a cup body 5 and a lid 7, and the lid 7 comprises an outer lid 71 and an inner lid 72 arranged at the bottom opening of the outer lid 71, and a sealing member two 73 is arranged between the outer lid 71 and the inner lid 72, and the inner lid 72 is provided with an opening to expose the sealing member two 73, and the exposed part of the sealing member two 73 is provided with a gap 731, and the gap 731 is forced to open.

[0129] Meanwhile, the outer lid 71 is provided with at least one air hole one 711 at the top, and the air hole one 711 is in communication with the inner side of the sealing member two 73.

[0130] Therefore, in actual use, through the arrangement of the gap 731, it can be closed when not in use, at this time, the closed gap 731 can prevent water vapor from overflowing, and when ventilation is needed, the gap 731 is forced to open, and the air hole 711 is in communication with the inner side of the sealing member two 73, thereby forming an air flow channel. Compared with only relying on the gap, the flowability of the utility model is better, the exhaust effect is better, and a guide column is not needed, thereby simplifying the structure.

[0131] Meanwhile, the gap 731 itself has the shape that: first, the cross section of the gap 731 is V-shaped, and the opening of the V-shaped is arranged at the side of the sealing member two 73 close to the cup body 5, that is, small at the top and large at the bottom. The large bottom is to facilitate the entry of gas, and the small top is to minimize the exhaust of gas when closed.

[0132] As shown in Figure 23 In the air flow channel, a flow splitting and limiting structure is further arranged, wherein the flow splitting structure is that: first, at least two second flanges 712 are arranged on the inner side of the outer lid 71, and a flow splitting opening 713 is arranged between the two adjacent second flanges 712.

[0133] Therefore, in actual use, through the arrangement of the flow splitting opening 713, the gas can be split to the vicinity close to the air hole 711, thereby facilitating the exhaust of the gas.

[0134] Meanwhile, the flow limiting structure is that: first, a second baffle 714 is arranged on the inner side of the outer lid 71, the top of the second baffle 714 is located outside the air hole 711, and the bottom of the second baffle 714 abuts against the sealing member two 73.

[0135] Therefore, in actual use, the second baffle 714 has multiple uses. Since the top of the second baffle 714 is located outside the air hole 711, the gas is limited from flowing to the range outside the air hole 711, and since the bottom of the second baffle 714 abuts against the sealing member 73, the sealing member 73 can be extruded to ensure the stability of the installation of the sealing member 73.

[0136] As shown in Figure 2As shown, the mounting structure of the second sealing member 73: first, the second sealing member 73 includes a visible part 732 and a connecting part 733 outside the visible part 732, and the visible part 732 is provided with a gap 731, and the inner cover 72 is provided with a hole to expose the visible part 732, and the inner side of the inner cover 72 is provided with a mounting groove 721 for placing the connecting part 733.

[0137] Therefore, in actual use, the sealing member 73 is placed on the inner side of the inner cover 72, at which time the connecting part 733 is located in the mounting groove 721, and the visible part 732 is exposed through the hole of the inner cover 72.

[0138] At the same time, the bottom of the second baffle 714 is in abutment with the connecting part 733 and is matched with the mounting groove 721 to press and limit the connecting part 733, thereby ensuring stable installation. Moreover, in order to make the installation more stable, the mounting groove 721 is provided with a protrusion 722, and the protrusion 722 is in interference fit with the second sealing member 73. In addition to this sealing, the water cup body 5 and the cover 7 are also provided with a third sealing member to prevent gas from flowing in other directions.

[0139] Secondly, the outer cover 71 and the inner cover 72 are connected by buckling, that is, the inner wall of the outer cover 71 is provided with a buckle 715, and the outer side of the inner cover 72 is provided with a clamping groove 723 corresponding to the buckle 715. Compared with the existing screw connection, the buckle connection is more convenient and convenient to install.

[0140] As shown in the drawings, Figure 28 It can be seen that the bottom or side wall of the water cup body 5 is provided with a heating plate 1. The conventional design is to fix the ceramic heating sheet with glue, but this heating method has low heat efficiency, slow heat transfer, and uneven heat transfer, and the ceramic sheet is also easy to break.

[0141] Therefore, the heating plate 1 of the utility model is made of metal and printed with a heating body, and the heating body adopts a heating wire 11, and the two ends of the heating wire 11 are provided with a wiring body 12. At the same time, the water cup body 5 and the heating plate 1 are welded. Because metal has good conductivity and is firm and durable, such as aluminum plate, and the printed heating wire 11 is not easy to be damaged by large current, so the service life is longer and it is not easy to be damaged.

[0142] The coverage and path of the heating wire 11 are not limited, and can be set as needed. At the same time, the wiring body 32 can be connected by a solder pad, or can be a terminal post, or can also be a spring contact.

[0143] At the same time, the heating plate 1 is provided with a thermistor 13, and the conventional design is to paste a thermistor 13 with tin foil paper, so that the temperature control is delayed and not accurate.

[0144] Therefore, the thermistor 13 of this utility model is directly welded to the heating plate 3, so that the temperature is more real-time and accurate.

[0145] like Figures 26-28 As shown, the existing structure of the water cup body 5 is that the assembly frame 30 extends its claws to hold the edge of the support ring located below the water cup body 5. Therefore, there is an additional support ring component here. Furthermore, the circuit board 3 40 is directly set on the top of the assembly frame 30 and located directly below the water cup body 5. Therefore, the heat generated during heating will affect the circuit board 3 40.

[0146] In this regard, the present invention adopts a different structure. First, an assembly rack 30 is provided inside the cup body 200, and the assembly rack 30 includes a support 301 and a mounting plate 302 disposed on the support 301, and a circuit board 40 is disposed between the support 301 and the mounting plate 302.

[0147] Therefore, in actual use, there is a mounting plate 2 302 on top of circuit board 3 40, which can insulate heat and thus protect circuit board 3 40.

[0148] At the same time, the mounting plate 2 302 is provided with at least two plug-in interfaces 303, and the inner wall of the plug-in interface 303 is provided with a protrusion 304. The heating area includes the water cup body 5, and the outer side of the water cup body 5 is provided with at least two connecting plates 51. The bottom of the connecting plate 51 is located inside the plug-in interface 303 and a snap-fit ​​hole 511 is opened corresponding to the protrusion 304.

[0149] Therefore, in actual use, the bottom of the connecting plate 51 is located inside the insertion interface 303, and the protrusion 304 is matched with the snap-fit ​​hole 511, so that the water cup body 5 is set on the mounting plate 302.

[0150] Compared to claws, plates and protrusions are easier to form, and the absence of a support ring simplifies the structure.

[0151] In order to make the installation more stable and to avoid the heating plate 1 at the bottom from sticking to other components, at least one support block 305 is provided on the mounting plate 302, and the support block 305 includes a side plate 306 and a pad 307 disposed on one side of the side plate 306.

[0152] Therefore, in actual use, the pad 307 is located at the bottom of the water cup body 5, thus preventing the heating plate 1 from touching other parts. At the same time, the side plate 306 is attached to the outside of the water cup body 5, thus preventing the water cup body 1 from tilting. In addition to being located at the bottom of the water cup body 5, the heating plate 1 is also located on the outer wall of the water cup body 5, in which case the heating plate 5 will be adapted to the side plate 306.

[0153] like Figures 18-22As shown, since the motor and the heating plate 5 generate heat during operation, and also generate heat during charging, a ventilation structure is required, but a waterproof structure is also required to prevent water from entering. The charging assembly 50 and the key assembly 60 are close to the heat generating place, so it is more appropriate to set them in the charging assembly 50 and the key assembly 60, but since the key assembly 60 is not convenient to punch, it is set in the charging assembly 50.

[0154] The specific structure is as follows: Figure 18 As shown, the cup body 200 is provided with a charging assembly 50 on one side, and the charging assembly is located on one side of the heating area, and the charging assembly 50 includes a circuit board one 501, a mounting member 502 and a silica gel cover 503. The mounting member 502 is arranged on the cup body 200, and the inner and outer sides of the mounting member 502 are connected with the circuit board one 501 and the silica gel cover 503 respectively.

[0155] At the same time, the circuit board one 501 is provided with a charging connector 504, and the mounting member 502 is provided with an opening to expose the charging connector 504, and the mounting member 502 is provided with a ventilation hole two 505 on one side of the charging connector 504, and the inner side of the mounting member 502 is provided with a waterproof and breathable film 506 corresponding to the ventilation hole two 505.

[0156] Therefore, in actual use, by locating the charging assembly 50 on one side of the heating area and providing the waterproof and breathable film 506, the heat generated by the heating area and the charging assembly 50 is discharged through the waterproof and breathable film 506, and at the same time of ventilation, water is also avoided to be introduced into the cup body 200. Moreover, the charging assembly 50 is located on one side of the cup body 200, so the heat generated in the cup body 200, such as the motor, is also discharged through the waterproof and breathable member.

[0157] The charging connector 504 can adopt a type-c interface, and the waterproof and breathable film 24 is a new type of high polymer waterproof material. The existing structure has the principle that the spacing between gas molecules is large, and in the diffusion process, it can pass through the holes of the waterproof and breathable film 24. The spacing between liquid molecules is smaller than the spacing of the holes, and under the action of surface tension, the liquid molecules cannot pass through the waterproof and breathable film 24, that is, the waterproof effect is achieved.

[0158] At the same time, as shown in Figures 18-19 The specific structure of the charging assembly 50 is as follows: first, the circuit board one 501 is provided with a wiring terminal one 507, and the circuit board three 40 is provided with a wiring terminal two 401, and the wiring terminal one 507 and the wiring terminal two 401 are connected through a wire.

[0159] The third circuit board 40 is a main circuit board for controlling the operation of various components of the coffee machine, and is connected to the terminal 507 and the terminal 401 through wires to achieve electrical connection between the third circuit board 10 and the first circuit board 501. Therefore, compared with the existing coffee machine which only has one main circuit board, the first circuit board 501 is an independent structure relative to the third circuit board 40, so that the position of the first circuit board 501 is closer to the sealing ring and the waterproof and breathable film 506, which can better achieve the functions of air permeability and waterproofness.

[0160] Secondly, the structure of the silica gel cover 503 is as follows: firstly, the silica gel cover 503 is provided with a plug-in ring 5031 corresponding to the charging connector 504, and the plug-in ring 5031 is provided to achieve the function of sealing and waterproofness.

[0161] Meanwhile, the silica gel cover 503 is provided with a clamping column 5032 on the inner side, and the mounting piece 502 is provided with a connecting hole 5021 corresponding to the clamping column 5032, and the outer side of one end of the clamping column 5032 passing through the connecting hole 5021 is provided with a limiting block 5033, and the length and width dimensions of the limiting block 5033 are greater than the length and width dimensions of the connecting hole 5021.

[0162] Therefore, in actual use, the silica gel cover 503 and the mounting piece 502 are connected by the clamping column 5032 passing through the connecting hole 5021, and the clamping column 5032 is prevented from being separated from the connecting hole by the limiting block 5033 abutting against the inner side of the mounting piece 502.

[0163] Then, the structure of the mounting piece 502 is as follows: firstly, the cup body 200 is provided with a mounting hole two for placing the charging assembly 50, and a sealing ring is arranged between the inner wall of the mounting hole two and the outer side of the mounting piece 502, and the inner wall of the mounting hole two is provided with a convex strip two, and the inner side of the mounting piece 502 is provided with a clamping plate 5023, and the outer side of the clamping plate 5023 is provided with a clamping block three 5024, and the side of the clamping block three 5024 close to the mounting piece 502 abuts against the convex strip two.

[0164] Therefore, in actual use, the sealing ring is provided to achieve the function of sealing and waterproofness, so as to improve the waterproof level, and the cup body 200 and the mounting piece 502 are connected by the clamping block three 5024 abutting against the convex strip two.

[0165] Meanwhile, the connection structure between the mounting piece 502 and the first circuit board 501 is as follows: firstly, the mounting piece 502 is provided with a hollow mounting column 5022 on the inner side, and the first circuit board 501 is provided with a hole 5012 corresponding to the mounting column, and a fastener passes through the hole 5012 and penetrates into the mounting column 5022 to achieve the connection between the mounting piece 502 and the first circuit board 501. The fastener is a screw.

[0166] And before the fastener connection, need preliminary positioning, its structure is: first install piece 502 is provided with column 5025, and the circuit board one 501 is correspondingly provided with assembly hole 5011.

[0167] Thus in actual use, through the column 5025 and the assembly hole 5011 are adapted to realize connection, and before the fastener connection, install column 5022 and hole 5012 are preliminary positioned and aligned.

[0168] As shown in Figure 20 In order to better seal waterproof effect, the key assembly 60 structure is also optimized, and the specific structure is: first cup body 200 the other side is provided with key assembly 60, and cup body 200 is provided with circuit board two 70 inside key assembly 60, and key assembly 60 includes light transmission piece one 601 and press plate 602 provided on light transmission piece one 601, and circuit board two 70 is provided with button 701 corresponding to press plate 602, and light transmission piece one 601 has elasticity and is twice injection molded with cup body 200.

[0169] Thus in actual use, through the light transmission piece one 601 and the cup body 200 twice injection molding, so that the light transmission piece one 601 and the cup body 200 are actually integrated structure without seam or gap, compared with the split structure of the key, the cup body is assembled by gluing or buckle, the sealing waterproof effect of twice injection molding is better, and the waterproof level is higher than that of the existing coffee machine.

[0170] Among them, twice injection molding is a kind of plastic material in the first plastic mold forming, taking out the formed parts, and then injecting the same or another kind of plastic material into the second forming mold.

[0171] And the button 701 generally will match the reminder light, so the circuit board two 70 is provided with illuminant 702, and in order to better seal waterproof effect, the cup body 200 is provided with light transmission piece two 603 corresponding to the illuminant 702, and the light transmission piece two 603 and the cup body 200 are twice injection molded.

[0172] As shown in Figures 20-22 The specific structure of the key assembly 60 is: it also includes decorative ring 604, and the light transmission piece one 601 is provided with decorative ring 604 outside. At the same time, the structure between the decorative ring 604 and the light transmission piece one 601 is: first, the light transmission piece one 601 is provided with convex ring 6011, and the convex ring 6011 is provided with convex plate 6012 outside, and the decorative ring 604 is sleeved outside the convex ring 6011, and the convex plate 6012 is located between the decorative ring 604 and the cup body 200.

[0173] Second, the structure between the decorative ring 604 and the cup body 200 is: first, the cup body 200 is provided with a glue groove three outside the light-transmitting piece one 601, and the inner side of the decorative ring 604 is located in the glue groove three.

[0174] Then, the structure between the pressing plate 602 and the light-transmitting piece one 601 is: first, the light-transmitting piece one 601 is provided with a convex ring 6011, and the light-transmitting piece one 601 is provided with a mounting portion 6013 in the convex ring 6011, and the inner side of the pressing plate 602 is provided with a mounting groove three 6021 corresponding to the mounting portion 6013, and the top of the mounting portion 6013 is provided with a glue groove one 6014, and the inner side wall of the convex ring 6011 and the outer side wall of the mounting portion 6013 are the glue groove two 6015.

[0175] Therefore, in the actual use process, the pressing plate 602 is first sleeved and clamped and fixed by glue, wherein the sleeved and clamped structure is that the mounting portion 6013 is matched with the mounting groove three 6021, and here the mounting portion 6013 can be different in diameter from top to bottom, so as to limit the position of the pressing plate 602.

[0176] Moreover, the glue groove one 6014 and the glue groove two 6015 are provided, so that two places are pasted, and the pressing plate 602 is installed more stably.

[0177] The above shows and describes the basic principle and main characteristics of the utility model and the advantages of the utility model. 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, and these changes and improvements all fall within the scope of the utility model.
