[0039] Reference Figure 1-Figure 14 A coffee machine, comprising a shell 1, a bracket 2, a main body 3, a water inlet sealing plate assembly 4 and a water outlet sealing plate assembly 5; the shell 1 has a first installation cavity 6, the first installation cavity 6 is provided with a first opening at the side, and the first opening is opened and closed by a detachable cover plate 8; the bracket 2 has a second installation cavity, the bracket 2 is detachably mounted in the first installation cavity 6, and the second installation cavity has a second opening; the main body 3 is detachably mounted on the second installation cavity 7, the main body 3 has a brewing cavity, and the two ends of the brewing cavity are respectively provided with a water inlet 9 and a water outlet 10, and the brewing cavity is provided with a water inlet 9 and a water outlet 10. The side of the cavity is provided with a material inlet 11 for coffee powder to enter; the main body 3 can enter and exit at the first opening and the second opening; the water inlet sealing plate assembly 4 includes a first sealing plate 12, a water inlet pipeline and a first power source 13, the first sealing plate 12 is movably installed in the main body 3, the first sealing plate 12 is configured to be able to open and close the water inlet 9, the first power source 13 is installed on the bracket 2, and the first power source 13 drives the first sealing plate 12 to move; the water outlet sealing plate assembly 5 is installed on the bracket 2, the output end of the water outlet sealing plate assembly 5 is configured to be able to slide in the brewing chamber, and the water outlet sealing plate assembly 5 has a water outlet channel 14.

[0040] The specific operating principle of the above embodiment is as follows: in the initial state, the first sealing plate 12 closes the water inlet 9, and the coffee powder enters from the feed inlet 11, and then the output end of the water outlet sealing plate assembly 5 moves into the brewing chamber, and cooperates with the first sealing plate 12 to form a closed cavity in the brewing chamber, and then high-temperature water is injected through the water inlet pipeline to brew the coffee powder. After brewing, the output end of the water outlet sealing plate assembly 5 continues to slide into the brewing chamber to squeeze the brewed coffee out of the water outlet channel 14. When assembling the above-mentioned embodiment, the main body 3, the water inlet sealing plate assembly 4 and the water outlet sealing plate assembly 5 can be first installed on the bracket 2, and then installed as a whole in the first installation cavity 76 after assembly. Compared with directly installing the main body 3, the water inlet sealing plate assembly 4 and the water outlet sealing plate assembly 5 into the shell 1, the assembly process can be optimized (if the main body 3, the water inlet sealing plate assembly 4 and the water outlet sealing plate assembly 5 are directly installed in the shell 1, it is necessary to work in the shell 1 for a long time, and the operating space in the shell 1 is not large, resulting in low work efficiency); in addition, the main body 3 can be moved out separately relative to the bracket 2, and the water outlet sealing plate assembly 5 and the first power source 13 are located on the bracket 2, which can simplify the structure of the main body 3 and reduce the size of the main body 3, making it convenient for the disassembly and assembly of the main body 3.

[0041] like Figure 3-Figure 6As shown, in some embodiments, the water inlet sealing plate assembly 4 further includes a driving plate 15 and an intermediate plate 16, one end of the driving plate 15 is rotatably mounted in the main body 3 through a first rotating shaft 17, the other end of the driving plate 15 is hinged to one end of the intermediate plate 16, and the other end of the intermediate plate 16 is hinged to the first sealing plate 12 through a second rotating shaft 18, a first guide groove 19 and a second guide groove 20 are provided on the inner side wall of the main body 3, the end of the second rotating shaft 18 is located in the first guide groove 19, a guide column 21 is provided on the first sealing plate 12, and the end of the guide column 21 is located in the second guide groove 20, and the first power source 13 drives the driving plate 15 to move. The driving plate 15, the intermediate plate 16 and the first sealing plate 12 are all located in the main body 3, and the motion trajectory of the first sealing plate 12 can be limited by combining the first guide groove 19 and the second guide groove 20. The setting of the driving plate 15 and the intermediate plate 16 can amplify the power output from the first power source 13, so as to provide sufficient power for the first sealing plate 12. The water inlet sealing plate assembly 4 has a simple and ingenious structure, occupies a small volume, is convenient for being separated from the first power source 13, and operates stably and reliably.

[0042] like Figure 3-Figure 6 As shown, in some embodiments, in order to facilitate the discharge of residues, the main body 3 includes an inclined section 22 and a horizontal section 23, the brewing chamber is located at the inclined section 22, the horizontal section 23 is connected to the water inlet 9, and a residue discharge port 24 is provided at the lower part of the connection, and the drive plate 15 and the middle plate 16 are located in the horizontal section 23 away from the end of the residue discharge port 24. After the coffee is brewed, the coffee residues are generally attached to the first sealing plate 12, so that when the first sealing plate 12 opens the water inlet 9, the coffee residues will automatically be discharged from the brewing chamber, and then leave the main body 3 from the residue discharge port 24, and then enter the waste bucket, which is located in the first installation cavity 76 and below the residue discharge port 24. After the waste bucket collects enough residues, it can be moved out and poured into a trash can and then put back to its original place. The above-mentioned embodiment of the main body 3 has a reasonable layout, which is conducive to the discharge of residues and simplifies the overall structure.

[0043] like Figure 3-Figure 6As shown, in some embodiments, the movement trajectory of the first sealing plate 12 can be designed by the shapes of the first guide groove 19 and the second guide groove 20. After brewing coffee, the coffee grounds need to be discharged. In order to discharge the coffee grounds smoothly, the first sealing plate 12 needs to be rotated to face the ground. For this purpose, the following design is made in this embodiment: the first guide groove 19 includes a first section and a second section connected to each other, the first section is parallel to the center line of the brewing chamber, and the angle between the second section and the first section is set to 90°-135°; the second guide groove 20 includes a third section and a fourth section connected to each other, the third section is parallel to the center line of the brewing chamber The angle between the third section and the fourth section is set to 90°-135°; under the limitation of the above-mentioned first guide groove 19 and the second guide groove 20, the first sealing plate 12 is close to the brewing chamber in a state perpendicular to the center line of the brewing chamber. After the first sealing plate 12 is fully opened, the first sealing plate 12 is tilted or vertically downward, so that the coffee grounds on the first sealing plate 12 can be discharged. The design of the first guide groove 19 and the second guide groove 20 can realize the first sealing plate 12 to run according to the set trajectory, which is very convenient. Compared with purely using a connecting rod structure to design the movement trajectory of the first sealing plate 12, it is simpler, saves parts, and saves internal space.

[0044] like Figure 3-Figure 6 As shown, in some embodiments, the first power source 13 includes a first motor 25 and a reducer 26, a connection hole 27 is provided at one end of the first rotating shaft 17 and the end of the first rotating shaft 17 extends outside the main body 3, the first motor 25 and the reducer 26 are installed on the bracket 2, the first motor 25 is connected to the input end of the reducer 26, and the output end of the reducer 26 is transmission-connected to the connection hole 27; the reducer 26 can be reduced by a worm gear or a gear box. The output end of the reducer 26 is connected to an output shaft 28, the output shaft 28 is rotatably installed on the bracket 2, and the output shaft 28 extends into the second mounting cavity 7. In this way, in the process of installing the main body 3 into the second installation cavity 7, the output shaft 28 is synchronously inserted into the connecting hole 27. The connecting hole 27 has a protrusion on the inner wall, and the output shaft 28 has a groove that cooperates with the protrusion on the outer wall. The protrusion and the groove cooperate to form a transmission connection. It can be seen from the above that the transmission connection between the first power source 13 and the first sealing plate 12 is very convenient. The first power source 13 is arranged on the bracket 2 and does not cause any adverse effects on the drive of the first sealing plate 12. The structure is very clever and practical.

[0045] like Figure 3-Figure 6As shown, in some embodiments, the water inlet pipeline includes a first interface 29, a pipeline, and a water inlet channel 30 arranged in the first sealing plate 12. The first interface 29 is arranged on the side wall of the main body 3, and the first interface 29 is connected with the water inlet channel 30 through the pipeline; the bracket 2 is provided with a second interface 31, and the second interface 31 extends into the second installation cavity 7. The first interface 29 and the second interface 31 are plug-in connection structures. The connection between the first interface 29 and the second interface 31 can be completed synchronously during the process of installing the main body 3 into the second installation cavity 7, which is very convenient. The pipeline is located in the main body 3, that is, the pipeline cannot be observed outside the main body 3, and there is no problem of disordered pipeline layout, which reduces the possibility of pipeline entanglement or scratching.

[0046] like Figure 3-Figure 6 As shown, in some embodiments, the water outlet sealing plate assembly 5 includes a second sealing plate 32 and a second power source 33. The second sealing plate 32 is slidably mounted on the bracket 2, the second power source 33 is mounted on the bracket 2, and the output end of the second power source 33 is transmission-connected with the second sealing plate 32; the water outlet channel 14 is arranged through the second sealing plate 32. The second power source 33 is arranged as a second motor, the bracket 2 is provided with a gear 34 rotatably arranged, the gear 34 is provided with a threaded hole, one side of the second sealing plate 32 is fixedly connected with a screw 64, the screw 64 is threadedly connected with the threaded hole, and the output end of the second motor is transmission-connected with the gear; the side wall of the screw 64 is provided with a third guide groove 35, the bracket 2 is provided with a limit block 36, the limit block 36 is inserted into the third guide groove 35, thereby limiting the rotation of the screw 64 relative to the bracket 2, so that the screw 64 can only slide relative to the bracket 2. The operating principle of the water outlet sealing plate assembly 5 of the above embodiment is as follows: the second motor works, and the second motor drives the gear to rotate through the reduction gear set, and the gear cooperates with the screw 64. Since the screw 64 cannot rotate, the screw 64 can only slide relative to the bracket 2, thereby driving the second sealing plate 32 to slide in the brewing chamber. Of course, it can be understood by those skilled in the art that the second power source 33 can also adopt other embodiments, such as a cylinder or an oil cylinder or a linear motor drive.

[0047] like Figure 2-Figure 6 As shown, in some embodiments, a limit plate 37 is rotatably provided on the bracket 2, and the limit plate 37 is configured to open and close the second opening; a micro switch 38 is also provided on the bracket 2, and the micro switch 38 is used to detect the state of the limit plate 37. When the limit plate 37 is in a position to open the second opening, the coffee machine cannot work. Only when the limit plate 37 is in a position to close the second opening, the coffee machine can work normally. The limit plate 37 can prevent the main body 3 from accidentally sliding out, ensuring the normal operation of the coffee machine.

[0048] like Figure 2As shown, in some embodiments, a third rotating shaft 39 is provided in the lower middle part of the cover plate 8, a sinker 40 is provided at the opening, and an outward positioning groove 41 is provided on the sinker 40, the third rotating shaft 39 cooperates with the positioning groove 41, and the sinker 40 located at the lower part of the positioning groove 41 shrinks toward the inner side of the shell 1, providing space for the lower end of the cover plate 8 to rotate toward the inside of the shell 1, and the upper end of the cover plate 8 and the sinker 40 are connected by magnetic force. In some embodiments, a magnet is provided at the upper end of the cover plate 8, and a patch is provided at the corresponding position of the magnet on the sinker 40; in order to achieve a more stable connection, a card hole is provided on the sinker 40, and a card hook is provided on the upper end of the cover plate 8; when the cover plate 8 needs to be removed, the lower part of the cover plate 8 (located below the third rotating shaft 39) is pressed by hand, and the cover plate 8 can rotate around the third rotating shaft 39, and then the card hook is disengaged from the card hole, and the upper end of the cover plate 8 is disengaged from the sinker 40. At this time, the upper end of the cover plate 8 can be grabbed, and the cover plate 8 can be moved out as a whole, and then the main body 3 can be taken in and put. The structure is very simple and ingenious.

[0049] like Figure 7-10 As shown, in some embodiments, a mounting hole 42 is further provided on the upper part of the housing 1, a circuit board 43 is provided at the bottom of the mounting hole 42, a light source 44 and a switch module are provided on the circuit board 43, a key assembly 45 and a light-transmitting plate 46 are further installed in the mounting hole 42, the key assembly 45 is located above the switch module, the light-transmitting plate 46 is annular, the light-transmitting plate 46 is provided around the key assembly 45, and the light-transmitting plate 46 is located above the light source 44. In the above embodiment, by providing a light source 44 on the circuit board 43, the light emitted by the light source 44 is guided to surround the key assembly 45 through the light-transmitting plate 46, and the key assembly 45 is illuminated. Even if the coffee machine is in a dark environment, the user can still clearly observe the key assembly 45, thereby reducing erroneous operations. The present invention has a simple and practical structure and a significant effect.

[0050] like Figure 7-10 As shown, in some embodiments, the light-transmitting plate 46 has a light-entering surface 47 and a light-emitting surface 48, and the light entering from the light-entering surface 47 can reach the light-emitting surface 48 after two reflections; the main purpose of the light source 44 is to illuminate the periphery of the key assembly 45, so the power requirement of the light source 44 is relatively low, so only a small number of light sources 44 are needed to achieve it. The small number of light sources 44 will inevitably lead to the problem of concentrated light output. In this embodiment, the light emitted by the light source 44 is reflected at least twice before being emitted, so that the light emitted from the light-emitting surface 48 is more uniform, soft and not dazzling, giving people a very comfortable feeling. Of course, those skilled in the art can understand that the number of reflections between the light entering from the light-entering surface 47 and reaching the light-emitting surface 48 can be adjusted according to actual conditions. If the power of the light source 44 is relatively high, three reflections or four reflections can be set, etc.

[0051] like Figure 7-10As shown, in some embodiments, the light-transmitting plate 46 includes a light-incoming section 49, a light-emitting section 50 and a middle section 51, and the light-incoming section 49, the light-emitting section 50 and the middle section 51 are all annular, the diameter of the light-incoming section 49 is larger than that of the light-emitting section 50, the light-incoming surface 47 is located at one end of the light-incoming section 49, the other end of the light-incoming section 49 is connected to one end of the light-emitting section 50 through the middle section 51, the light-emitting surface 48 is located at the other end of the light-emitting section 50, a first chamfer is provided on the outside of the corner formed by the connection between the light-incoming section 49 and the middle section 51, and a second chamfer is provided on the outside of the corner formed by the connection between the light-emitting section 50 and the middle section 51. In the above embodiment, the light emitted by the light source 44 enters from the light-incoming surface 47, is reflected at the first chamfer to enter the middle section 51, and then is reflected at the second chamfer to enter the light-emitting section 50, and then is emitted from the light-emitting surface 48. The light-transmitting plate 46 with the above structure is easy to process, easy to assemble, and has low cost. The shape of the light-transmitting plate 46 can be designed according to the shape of the key assembly 45. If the key assembly 45 is square, the light-transmitting plate 46 can be set in a square ring shape.

[0052] like Figure 7-10 As shown, in some embodiments, the key assembly 45 includes a support member 52, an upper plate of the housing 1 and a key body 53, a protective layer is provided between the support member and the circuit board, the protective layer 54 covers the circuit board 43, the support member 52 is mounted on the circuit board 43, the support member 52 is provided with an annular mounting groove corresponding to the light-transmitting plate 46, the key body 53 can be mounted on the support member 52 in a liftable manner, the upper plate covers the middle section 51, and the diameter of the mounting hole 42 is adapted to the outer diameter of the light-emitting section 50. In the above embodiments, the upper plate and the support member 52 can be used to install and fix the light-transmitting plate 46, and at the same time, the side of the light-transmitting plate 46 except the light-entering surface 47 and the light-emitting surface 48 can be shielded to prevent light from leaking out; of course, those skilled in the art can understand that other methods can also be used to prevent light from leaking out, for example, the side of the light-transmitting plate 46 except the light-entering surface 47 and the light-emitting surface 48 can be painted with opaque paint to prevent light from leaking out.

[0053] like Figure 7-10 As shown, in some embodiments, in order to allow the light emitted by the light source 44 to enter the light incident surface 47, the support member 52 is provided with an avoidance hole 55 corresponding to the light source 44; or the support member 52 is provided to be transparent at the position corresponding to the light source 44, or the entire support member 52 is provided to be transparent, which is conducive to one-time processing and molding.

[0054] Among them, the protective layer 54 can prevent the button body 53 from damaging the circuit board 43. In order to prevent the light decay from being too serious, the protective layer 54 is set to be transparent as a whole, which is conducive to one-time processing and forming. Of course, those skilled in the art can understand that the protective layer 54 only needs to be set to be transparent at the corresponding light source 44.

[0055] like Figure 11-Figure 14As shown, in some embodiments, a coffee outlet structure is provided on the side wall of the shell 1, and the coffee outlet structure includes a transfer chamber 56. The interior of the transfer chamber 56 is hollow. A coffee inlet 57 is provided at the upper portion of the transfer chamber 56, and a coffee outlet 58 is provided at the lower portion.
