[0046] This utility model provides a coffee machine 100. For details, please refer to [link / reference needed]. Figure 1 and Figure 2 In this embodiment, the coffee machine 100 includes a main body 1 and a bean hopper assembly 2. The main body 1 has a receiving groove 11 with its opening facing upwards, and a first through hole 12 is provided at the bottom of the receiving groove 11. The bean hopper assembly 2 is detachably disposed in the receiving groove 11 from the opening of the receiving groove 11. The bean hopper assembly 2 includes a bean hopper body 21, and a hopper opening and a bean outlet communicating with the inner cavity of the bean hopper body 21. The bean outlet extends out of the receiving groove 11 from the first through hole 12. At least a portion of the bean hopper body 21 can be exposed from the opening of the receiving groove 11 and protrude from the main body 1, and the hopper opening is exposed outside the main body 1.

[0047] In this embodiment, the bean hopper assembly 2 can be used to store coffee beans. The coffee machine 100 can automatically feed coffee beans by taking them from the bean hopper assembly 2. A receiving slot 11 is provided on the top of the main body 1, with the opening of the receiving slot 11 facing upwards. The bean hopper assembly 2 is detachably disposed in the receiving slot 11 from the opening of the receiving slot 11. Thus, when placing the bean hopper assembly 2, the bottom of the bean hopper assembly 2 can be inserted into the receiving slot 11, and under its own weight, the bean hopper assembly 2 can fall smoothly into the receiving slot 11. Since at least a portion of the bean hopper body 21 is exposed outside the receiving slot 11 and protrudes from the main body 1, when removing the bean hopper assembly 2, it can be held and operated on the part of the bean hopper body 21 exposed outside the main body 1 to remove the bean hopper assembly 2 from the opening of the receiving slot 11. The bean hopper assembly 2 is easier to put into and take out of the main body 1, which makes cleaning and maintenance of the bean hopper assembly 2 more convenient. Furthermore, the opening of the bean hopper body 21 is exposed outside the main body 1 of the equipment, directly located on the outside of the main body 1. When loading beans, there is no need to disassemble or open the main body 1 of the equipment; coffee beans can be directly loaded through the opening, making the operation simpler and more convenient. It also makes it easier to observe the storage status of coffee beans inside the bean hopper body 21, thus simplifying coffee bean management.

[0048] The main body 1 of the device includes, but is not limited to, a housing, a grinding structure disposed within the housing, and a brewing structure. The housing is generally square in shape. When the coffee machine 100 is operating normally, the side with the liquid outlet is designated as the front, and the bean hopper assembly 2 is located on top of the main body 1. The grinding structure is located inside the housing, and preferably below the bean hopper assembly 2, for receiving coffee beans flowing from the outlet of the bean hopper assembly 2 and for grinding the coffee beans. Unless otherwise specified, all descriptions of orientation in this invention refer to the above description.

[0049] The housing includes a top plate, a receiving groove 11 formed on the top plate and recessed downward from the top plate toward the interior of the housing. The top plate has a planar area on one side of the receiving groove 11, which can be supported on a portion of the outer wall of the bean hopper assembly 2, such that at least a portion of the bean hopper assembly 2 can be exposed from the top of the device body 1 and is securely fixed.

[0050] It is understandable that the main body of the equipment 1 and the bean hopper component 2 can be connected and limited by a snap-fit ​​structure, magnetic structure, or screw connection structure, so that the bean hopper component 2 can be placed stably and reliably on the main body of the equipment 1.

[0051] There are multiple ways to connect the main body 1 of the device to the bean hopper component 2. Preferably, it combines... Figures 1 to 3As shown, a first enclosure 15 is provided on the main body 1, and the first enclosure 15 is arranged around the outer periphery of the opening of the receiving groove 11. The first enclosure 15 can be arranged in a full circle or a half circle. A second enclosure 251 is provided on the bean hopper assembly 2, and the second enclosure 251 is arranged around the outer periphery of the bean outlet. The shape of the second enclosure 251 can match the shape of the first enclosure 15, or the second enclosure 251 can at least partially fit with the first enclosure 15. The second enclosure 251 is sleeved on the inner side of the first enclosure 15 and forms a stop fit with the first enclosure 15 in the radial direction along the opening of the receiving groove 11. The first enclosure 15 limits the second enclosure 251 in the horizontal direction, thereby limiting the bean hopper assembly 2 in the horizontal direction.

[0052] The bean hopper assembly 2 sinks into the receiving groove 11 under its own weight. Without external force, the bean hopper assembly 2 will not detach from the receiving groove 11, thus restricting it vertically to the main body 1. Therefore, through the cooperation of the receiving groove 11, the first enclosure 15, and the second enclosure 251, the bean hopper assembly 2 is completely confined to the main body 1, making the loading and unloading of the bean hopper assembly 2 simpler and less strenuous. Furthermore, the bean outlet can protrude from the end of the second enclosure 251, allowing it to better extend into the first through hole 12 of the receiving groove 11, resulting in more directional bean dispensing and facilitating the connection between the grinding structure and the bean outlet.

[0053] Preferably, such as Figure 4 As shown, the first enclosure 15 is arranged in a complete ring shape, and the second enclosure 251 is also arranged in a complete ring shape, so that all parts of the circumference of the bean hopper assembly 2 can be restricted by the first enclosure 15, and the bean hopper assembly 2 is less likely to tip over after being placed on the main body of the equipment 1, making it more stable.

[0054] Furthermore, combined Figure 4 and Figure 5 As shown, the bean hopper assembly 2 also includes a ring-shaped shield 25. The shield 25 surrounds the outside of the bean hopper body 21, allowing the hopper opening of the bean hopper body 21 to extend from the upper end of the shield 25 and the bean outlet of the bean hopper body 21 to extend from the lower end of the shield 25. A second enclosure 251 is located at the bottom of the shield 25, restricting the horizontal movement of the shield 25 by the first enclosure 15, thereby restricting the horizontal movement of the entire bean hopper assembly 2. By covering the outside of the bean hopper body 21 with the shield 25, the appearance of the bean hopper body 21 is made more aesthetically pleasing. Moreover, by placing the second enclosure 251 on the shield 25, the shield 25 can be better connected to the equipment body 1 without affecting the internal cavity space of the bean hopper body 21, making the structure of the bean hopper body 21 simpler and thus easier to manufacture.

[0055] The opening of the bean hopper body 21 is roughly square to match the overall shape of the device body 1, allowing for a larger opening and easier pouring of coffee beans. In one embodiment, as... Figure 6 As shown, a partition 22 is provided in the inner cavity of the bean hopper body 21. The partition 22 divides the inner cavity of the bean hopper body 21 into a first compartment 23 and a second compartment 24. The first compartment 23 and the second compartment 24 can be used to store coffee beans of the same type or different types.

[0056] The first chamber 23 has a first opening and a first bean outlet 231 communicating with its inner cavity. Coffee beans can enter the first chamber 23 through the first opening, and the first bean outlet 231 is used to discharge coffee beans from the first chamber 23. The second chamber 24 has a second opening and a second bean outlet 241 communicating with its inner cavity. Coffee beans can enter the second chamber 24 through the second opening, and the second bean outlet 241 is used to discharge coffee beans from the second chamber 24.

[0057] Combination Figure 6 and Figure 7 As shown, the wall of the first chamber 23 extends at an incline toward the first bean outlet 231, so that the first bean outlet 231 is located at the lowest point of the first chamber 23. Therefore, after the coffee beans enter the first chamber 23, the coffee beans can roll down along the wall of the first chamber 23 and move toward the first bean outlet 231, so that the coffee beans can fall out of the first bean outlet 231 better, and will not accumulate in the first chamber 23, causing beans to get stuck. Similarly, the walls of the second chamber 24 are inclined and extend towards the second bean outlet 241, so that the second bean outlet 241 is located at the lowest point of the second chamber 24. After the coffee beans enter the second chamber 24, they can roll down along the walls of the second chamber 24 and move towards the second bean outlet 241, so that the coffee beans can fall out of the second bean outlet 241 more easily and will not accumulate in the second chamber 24, causing beans to get stuck.

[0058] Preferably, the first bean outlet 231 and the second bean outlet 241 are located on the same horizontal plane, so that the bean outlet positions are more consistent, thereby better connecting with the bean receiving device.

[0059] Since different types of coffee require different quantities of coffee beans to produce, it is preferable to combine [the following] to better control the amount of coffee beans dispensed from the first chamber 23 and the second chamber 24. Figure 6 and Figure 8 As shown, the bean hopper assembly 2 also includes a first bean outlet channel 232, a second bean outlet channel 242, a first cover 234, and a second cover 244.

[0060] The first bean outlet channel 232 connects the first chamber 23 and the first bean outlet 231. The first bean outlet channel 232 extends the bean outlet path, allowing the first bean outlet 231 to better extend beyond the shield 25 and connect with the grinding structure. The second bean outlet channel 242 connects the second chamber 24 and the second bean outlet 241. The second bean outlet channel 242 extends the bean outlet path, allowing the second bean outlet 241 to better extend beyond the shield 25 and connect with the grinding structure. Preferably, both the first bean outlet channel 232 and the second bean outlet channel 242 extend vertically to ensure smooth bean dispensing. The first cover 234 is movably disposed outside the bean chamber body 21 and can block and open the first bean outlet channel 232. The first cover 234 can be located at any position on the first bean outlet channel 232. By blocking or opening the first bean outlet channel 232, the opening or closing of the first bean outlet 231 is controlled. The second cover 244 is movably disposed outside the bean hopper body 21 and can block and open the second bean outlet channel 242. The second cover 244 can be disposed at any position in the second bean outlet channel 242. By blocking or opening the second bean outlet channel 242, the opening or closing of the second bean outlet 241 can be controlled. This makes it easier to control the amount of beans dispensed from the first bean outlet 231 and the second bean outlet 241, thereby better ensuring the taste of the coffee.

[0061] Two first through holes 12 are provided, both located at the bottom of the receiving groove 11. The bottom of the receiving groove 11 is the side opposite to its opening. The first bean outlet channel 232 and the second bean outlet channel 242 are respectively inserted into the two first through holes 12, and the first bean outlet 231 and the second bean outlet 241 can extend from their respective first through holes 12. The first bean outlet 231 and the second bean outlet 241 are located outside the receiving groove 11 to facilitate connection with the bean grinding structure.

[0062] In one embodiment, the first cover 234 and the second cover 244 can be arranged to move asynchronously. The first cover 234 and the second cover 244 can be manually driven. Alternatively, the first cover 234 can be driven to move by a first driving component, and the second cover 244 can be driven to move by a second driving component. The first driving component drives the first cover 234 to rotate or translate, thereby opening or blocking the first bean outlet channel 232. The second driving component drives the second cover 244 to rotate or translate, thereby opening or blocking the second bean outlet channel 242. The first cover 234 and the second cover 244 operate independently to control the bean dispensing from the first chamber 23 and the second chamber 24 respectively, achieving flexible control of bean dispensing.

[0063] In another embodiment, the first cover 234 and the second cover 244 are arranged to move synchronously. When the first cover 234 blocks the first bean outlet channel 232, the second cover 244 blocks the second bean outlet channel 242. When the first cover 234 opens the first bean outlet channel 232, the second cover 244 opens the second bean outlet channel 242. The first bean outlet 231 and the second bean outlet 241 open or close simultaneously. Two grinding structures can be correspondingly provided within the coffee machine 100, respectively connected to the first bean outlet 231 and the second bean outlet 241. This allows coffee beans in both chambers to fall into the two grinding structures simultaneously when the first and second bean outlets 231 and 241 are open. The two grinding structures can operate simultaneously, improving efficiency and increasing coffee-making efficiency.

[0064] When the first cover 234 and the second cover 244 are in a synchronous moving state, preferably, both the first bean outlet 231 and the second bean outlet 241 are located close to the partition 22, and the closer distance between the first bean outlet 231 and the second bean outlet 241 facilitates the connection between the first cover 234 and the second cover 244. Wherein, combined with Figures 6 to 8 As shown, the bean hopper assembly 2 also includes a drive gear 26, a transmission gear 27, and a drive handle 28. The drive gear 26 is rotatably located on the outside of the bean hopper body 21 and is connected to the first cover 234. The rotation of the drive gear 26 causes the first cover 234 to rotate as well. The transmission gear 27 meshes with the drive gear 26 and is connected to the second cover 244. The rotation of the transmission gear 27 causes the second cover 244 to rotate as well. One end of the drive handle 28 is located inside the first hopper body 23, and the other end of the drive handle 28 is connected to the drive gear 26. By driving the drive handle 28 to rotate, the drive gear 26 can rotate, causing the first cover 234 to rotate. At the same time, under the action of the drive gear 26, the transmission gear 27 can be driven to rotate, thereby causing the second cover 244 to rotate as well. The structure is simple and can realize the simultaneous opening and closing of the first cover 234 and the second cover 244, thus improving the bean dispensing efficiency.

[0065] When both the first cover 234 and the second cover 244 are closed, they are located inside the receiving groove. This ensures that when the bean hopper assembly 2 is removed from the main body 1, the first cover 234 and the second cover 244 are less likely to interfere with the top plate. Furthermore, when the bean hopper assembly 2 is removed, the first cover 234 and the second cover 244 are kept closed, preventing coffee beans from spilling out of the bean hopper main body 21.

[0066] Combined again Figure 6 and Figure 8As shown, a first clearance hole 233 is provided on the side wall of the first bean outlet channel 232, and a second clearance hole 243 is provided on the side wall of the second bean outlet channel 242. The wall of the receiving groove 11 is provided with a second through hole 13 corresponding to the first clearance hole 233, and a third through hole 14 corresponding to the second clearance hole 243. When the first cover 234 is in the position where the first bean outlet channel 232 is open, the first cover 234 can pass through the first clearance hole 233 and the second through hole 13, and the first cover 234 can rotate to the outside of the receiving groove 11 to open the first bean outlet channel 232. When the second cover 244 is in the position where the second bean outlet channel 242 is open, the second cover 244 can pass through the second clearance hole 243 and the third through hole 14, and the second cover 244 can rotate to the outside of the receiving groove 11 to open the second bean outlet channel 242. The first cover 234 and the second cover 244 have sufficient space to move around, and the receiving slot 11 can fit more closely to the bean hopper assembly 2, resulting in a more compact structure and less space occupation.

[0067] Moreover, both the transmission gear 27 and the drive gear 26 have semi-circular teeth, causing the first cover 234 and the second cover 244 to reciprocate between the open and closed states.

[0068] In addition, two limiting protrusions are provided on the outer side wall of the receiving groove 11. When in the open state, the transmission gear 27 and the drive gear 26 respectively form a stop engagement with the two limiting protrusions in the rotation direction to limit the opening degree of the first cover 234 and the second cover 244.

[0069] In one embodiment, at least a portion of the shield 25 is spaced apart from the outer side of the bean hopper body 21 to form a sandwich layer. At least one side of the shield 25 is provided with an air inlet 252, which is connected to the sandwich layer and exposed outside the receiving groove 11, so that external airflow can better enter the sandwich layer from the air inlet 252.

[0070] Combination Figure 4 and Figure 5 As shown, the coffee machine 100 also includes a heat dissipation channel 31 located outside the receiving slot 11, and a heat dissipation component 32 located within the heat dissipation channel 31. The heat dissipation channel 31 is adapted to connect the interlayer and the heating components (such as the bean grinding structure and / or various driving components) within the main body 1. The heat dissipation component 32 is used to guide airflow from the air inlet 252 into the interlayer, and through the interlayer into the heat dissipation channel 31 to flow towards the heating components, thereby better dissipating heat from the heating components and ensuring that the coffee machine 100 can work better. The heat dissipation component 32 may be equipped with a cooling fan. The heat dissipation channel 31 extends vertically, and the cooling fan is located at one end of the heat dissipation channel 31 near the interlayer and near the air inlet 252, allowing external cold airflow to enter the heat dissipation channel 31 more quickly, improving heat dissipation efficiency.

[0071] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
