They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] See Figure 1-Figure 7 The utility model discloses a bean silo installation structure, including a bean silo and a mounting assembly. The bean silo includes a bean silo body 10 and a bean silo base 20, and the bean silo body 10 is rotatably installed on the bean silo base 20. An outlet and an opening and closing assembly are provided at the bottom end of the bean silo body 10. When the bean silo body 10 rotates relative to the bean silo base 20, the opening and closing assembly can be linked to open or close the outlet of the bean silo body 10.

[0032] Specifically, a first connection portion is provided on the bean hopper base 20. The mounting assembly includes a mounting base 30 and a linkage ring 40. The linkage ring 40 is rotatably mounted on the mounting base 30 and is provided with a locking portion. Furthermore, a second connection portion and a locking member are provided on the mounting base 30. The second connection portion is detachably connected to the first connection portion to connect the mounting base 30 to the bean hopper body 10. The locking member is movable toward or away from the locking member. When approaching the locking member, the locking member locks with the locking member. After the bean hopper body 10 is connected to the mounting base 30, the locking member is pressed against the bean hopper body 10, moving the locking member away from the locking member and unlocking it.

[0033] Based on the above structure, when using the bean silo mounting structure of the present invention, the bean silo body 10 and the bean silo base 20 are rotated and assembled, and then the first connection portion of the bean silo base 20 corresponds to the second connection portion of the mounting seat 30. In this way, the bean silo base 20 is connected to the second connection portion of the mounting seat 30 through the first connection portion, thereby realizing the connection between the bean silo base 20 and the mounting seat 30.

[0034] After the bean hopper base 20 is installed on the mounting seat 30, the bean hopper body 10 can press the locking piece on the mounting seat 30, so that the locking piece and the locking portion of the locking ring are disengaged. Since the bean hopper base 20 is connected to the mounting seat 30, and the linkage ring 40 rotates the mounting seat 30 before unlocking, after the bean hopper base 20 is assembled to the mounting seat 30, the linkage ring 40 is pressed by the bean hopper body 10 to unlock it, and then it is linked to the bean hopper body 10. At this time, the bean hopper body 10 can be rotated, and the bean hopper body 10 can drive the linkage ring 40 to rotate together.

[0035] It should be noted that the bean hopper is generally installed above the grinding chamber of a structure such as a coffee machine or a bean grinder. Therefore, when cleaning the blade disc inside the machine base, the bean hopper must be removed. After the bean hopper is removed, the bean hopper body 10 that controls the opening or closing of the opening and closing assembly of the bean hopper is prone to rotation under external force. At this time, the opening and closing assembly is not in a closed state or a fully open state. After the bean hopper is reassembled, the bean hopper body 10 needs to be readjusted to bring the opening and closing assembly to the initial state of full opening or full closing.

[0036] In this embodiment, after the bean hopper base 20 is installed into the mounting seat 30, the first connecting portion and the second connecting portion are aligned before installation. At the same time, the bean hopper body 10 can be linked with the linkage ring 40 of the mounting seat 30 after the bean hopper base 20 is installed. That is, the bean hopper body 10 is installed at the corresponding position each time, and the position of the bean hopper body 10 is aligned each time before it can be rotated. There is no need to adjust the position of the bean hopper body 10 separately. That is, the position of the bean hopper body 10 when the bean hopper base 20 is installed or removed is at the position where the first connecting portion and the second connecting portion are connected, thereby realizing positioning and disassembly.

[0037] Furthermore, the locking member includes a locking rod 51 and an elastic component 52. The corresponding locking portion is a locking hole. The locking rod 51 is connected to the mounting base 30 via the elastic component 52. The elastic component 52 can provide an elastic stress, which drives the locking rod 51 toward the locking hole. The locking rod 51 can be pressed by the bean hopper body 10 to compress the elastic component 52.

[0038] Based on this structure, after the bean hopper is detached from the mounting base 30, the locking rod 51 loses the pressure of the bean hopper body 10, and the elastic component 52 returns to its original position. The elastic stress provided by the locking rod 51 drives the locking rod 51 to extend into the locking hole. In this way, the linkage ring 40 is locked and cannot rotate relative to the mounting base 30. The linkage ring 40 can be locked in the detached position of the bean hopper.

[0039] After the bean hopper is installed on the mounting base 30 again, the first connection portion of the bean hopper base 20 corresponds to the position of the second connection portion of the mounting base 30, and the first connection portion of the bean hopper base 20 is assembled correspondingly with the second connection portion of the mounting base 30. After the bean hopper base 20 is installed, the bean hopper body 10 presses the locking rod 51, driving the locking rod 51 out of the locking hole position, and the linkage ring 40 can be linked with the bean hopper body 10, and the bean hopper body 10 can rotate.

[0040] It should be noted that the locking rod 51 can only be extended to the locking hole and locked when the linkage ring 40 is rotated to the position where the locking hole corresponds to the locking rod 51 again. At this time, the bean hopper can be detached. That is, each locking and unlocking is at the corresponding position, so that the disassembly and assembly positions of the bean hopper are the same.

[0041] Furthermore, a linkage member 12 is specifically provided on the bean hopper body 10. When the bean hopper body 10 is connected to the mounting base 30, the linkage member 12 can press the locking rod 51 and interlock with the linkage ring 40. Thus, after the first connecting portion of the bean hopper base 20 is connected to the second connecting portion of the mounting base 30, the linkage member 12 of the bean hopper body 10 can correspondingly press the locking rod 51 and interlock with the linkage ring 40. In other words, while the locking rod 51 is unlocked by the linkage member 12, the bean hopper body 10 and the linkage ring 40 are also interlocked via the linkage member 12. After unlocking, the linkage ring 40 synchronizes with the rotation of the bean hopper body 10.

[0042] Furthermore, a positioning groove 42 can be provided on the linkage ring 40, and a locking hole can be provided in the positioning groove 42. The locking hole can correspond to the locking rod 51 when the linkage ring 40 rotates, so that the locking rod 51 is locked into the locking hole; the linkage part 12 is inserted into the positioning groove 42 and presses the locking rod 51 after the bean hopper body 10 is installed on the mounting seat 30.

[0043] In this way, after the bean hopper is installed in the mounting seat 30, the first connecting part of the bean hopper body 10 is connected to the second connecting part of the mounting seat 30, and at the same time, the linkage part 12 of the bean hopper body 10 can be snapped into the positioning groove 42. During the process of snapping into the positioning groove 42, the locking rod 51 in the positioning groove 42 can be pushed away from the locking hole to unlock the linkage ring 40. At the same time, the linkage of the linkage ring 40 and the bean hopper body 10 is achieved through the snap connection between the linkage part 12 and the positioning groove 42.

[0044] It should be noted that if the positioning slot 42 is not provided on the linkage ring 40, the locking rod 51 can be directly extended from the linkage ring 40. After the bean hopper base 20 is installed in the mounting seat 30, the bean hopper body 10 can be installed to press against the protruding locking rod 51, and linkage can also be achieved through magnetic attraction. That is, a magnetic attraction structure is provided at the corresponding pressing position. Alternatively, a notch can be provided on the bean hopper body 10, and a protrusion can be provided on the linkage ring 40. After the bean hopper base 20 is installed, the end face of the bean hopper body 10 directly presses against the protruding locking rod 51, and the protrusion fits into the notch of the bean hopper body 10, thereby achieving linkage between the two.

[0045] Furthermore, a positioning notch 32 can be provided on the mounting seat 30. The positioning notch 32 corresponds to the positioning groove 42 when the linkage ring 40 rotates, and the linkage member 12 is inserted into the positioning groove 42 through the positioning notch 32. That is, when the bean hopper base 20 is installed into the mounting seat 30, the linkage member 12 of the bean hopper body 10 can also be positioned and inserted through the positioning notch 32 and be inserted into the positioning groove 42 of the linkage ring 40. The positioning notch 32 avoids the structure of the linkage member 12, thereby preventing interference during the installation of the bean hopper body 10 and ensuring smooth assembly and disassembly.

[0046] The positioning notch 32 is used for installation positioning. The linkage member 12 of the bean hopper body 10 can only be installed when it rotates to the position corresponding to the positioning notch 32 of the linkage member 12, thus realizing installation linkage. In this way, the position of each installation or removal is consistent, realizing positioning and disassembly.

[0047] Furthermore, the linkage 12 includes a first positioning arm 121 and a second positioning arm 122, and a positioning rib 43 can be provided in the positioning groove 42. The above-mentioned positioning rib 43 divides the positioning groove 42 into a first groove section and a second groove section, and the locking hole is provided in the first groove section. The first positioning arm 121 is inserted into the first groove section and is used to press the locking rod 51, and the second positioning arm 122 is inserted into the second groove section.

[0048] In this embodiment, the linkage member 12 forms a pressing structure and a linkage structure with the first positioning arm 121 and the second positioning arm 122 respectively. During the installation of the bean hopper body 10, the first positioning arm 121 can penetrate through the positioning notch 32 and be stuck in the first groove section to press the locking rod 51, while the second positioning arm 122 is stuck in the second groove section. That is, the first positioning arm 121 realizes pressing, and the second positioning arm 122 realizes linkage, and the pressing action and the linkage action are synchronized.

[0049] Furthermore, the top ends of the first positioning arm 121 and the second positioning arm 122 are connected by a connecting arm 123; the connecting arm 123 can abut against the top end of the positioning rib 43. During the installation of the bean hopper body 10, the first positioning arm 121 and the second positioning arm 122 are respectively limited by the first groove section and the second groove section, so that the connecting arm 123 abuts against the top end of the positioning rib 43 to achieve positioning, indicating that the assembly is in place, and the bean hopper assembly in place prompt function is activated.

[0050] Furthermore, a limiting notch 21 is provided on the bean silo base 20, and a limiting protrusion 31 is correspondingly provided on the mounting seat 30. When the bean silo base 20 and the mounting seat 30 are assembled, the bean silo base 20 is installed into the mounting seat 30, and the limiting protrusion 31 on the mounting seat 30 is snapped into the limiting notch 21. Based on this structure, the limiting notch 21 is the first connecting part, and the limiting protrusion 31 is the second connecting part.

[0051] Of course, the first connecting portion and the second connecting portion can also be implemented by a snap-on connection method, or a spring pin structure and a pin hole structure, as long as a detachable connection structure between the mounting seat 30 and the bean hopper base 20 can be achieved.

[0052] Furthermore, in this embodiment, a touch sheet 41 may be provided on the linkage ring 40 , and a corresponding touch switch may be provided on the mounting seat 30 . The touch sheet 41 may touch the touch switch when the linkage ring 40 rotates.

[0053] The bean hopper is typically mounted above the grinding chamber of a coffee machine or bean grinder. Only after the bean hopper is fully assembled can the bean hopper's opening and closing assembly be opened to initiate bean grinding. To prevent the burr disc from being accidentally activated after the bean hopper is removed, a touch switch for activating the burr disc is positioned within the rotational path of the linkage ring 40. Activation occurs only when the touch pad 41 of the linkage ring 40 is rotated and contacts the touch switch. In other words, only after the bean hopper is assembled to the mounting base 30 and the linkage ring 40 is unlocked by the pressure of the bean hopper body 10 can the hopper body 10 drive the linkage ring 40 to rotate. Once the linkage ring 40 rotates, the touch pad 41 contacts the touch switch, activating the burr disc.

[0054] After the bean hopper is detached, the linkage ring 40 rotates to a state where the touch sheet 41 is disengaged from the touch switch, and the locking hole of the linkage ring 40 is locked correspondingly to the locking piece. After the bean hopper is detached, the linkage ring 40 is locked and cannot move, so the touch sheet 41 will not be accidentally touched.

[0055] Furthermore, the opening and closing assembly of this embodiment includes at least three opening and closing blades 11. These three opening and closing blades 11 can cooperate to form a closed structure by rotating toward each other, and can open the opening by rotating away from each other. Specifically, the opening and closing blades 11 are rotatably connected to the bean hopper body 10. Guide grooves 111 are provided on the opening and closing blades 11, and guide posts 22 are provided on the bean hopper base 20. The guide posts 22 slidably engage the guide grooves 111 and guide the rotation of the opening and closing blades 11 during sliding to open or close the opening.

[0056] The guide groove 111 is an arc groove. When the bean hopper body 10 rotates, the bean hopper body 10 rotates relative to the bean hopper base 20, and the guide column 22 of the bean hopper base 20 slides in the guide groove 111, that is, slides along an arc trajectory, thereby guiding the opening and closing blades 11 to open or close.

[0057] Example 2,

[0058] A coffee machine includes the bean hopper mounting structure of Example 1. The mounting base 30 of the bean hopper mounting structure can be fixedly connected to the machine base or formed by the machine base. After the bean hopper mounting structure is assembled to the coffee machine, the opening of the bean hopper body 10 corresponds to the grinding chamber of the coffee machine. When grinding coffee beans, the bean hopper body 10 is rotated, and the opening of the bean hopper body 10 is opened by the opening and closing assembly. The coffee beans in the bean hopper fall into the grinding chamber of the coffee machine, and the drive structure of the coffee machine drives the cutter assembly to grind the coffee beans.

[0059] It should be noted that the function structure and principle of the specific blade disc mounting structure for the coffee machine are the same as those in Example 1, and the other structures of the coffee machine are all existing technologies and will not be described in detail here.

[0060] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
