Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, and in particular to a coffee hopper feeding structure and a coffee grinder containing the same. Background Technology

[0002] Existing home or commercial coffee machines typically use a removable bean hopper for adding beans and cleaning. The connection between the bean hopper and the main unit is usually a snap-fit, clip, or simple screw-on structure. The feed inlet is often blocked by a single baffle, slide valve, or cap.

[0003] However, when users need to clean the coffee beans, they often forget to close the bean hopper baffle when they take out the bean hopper, causing the coffee beans inside the hopper to fall everywhere, increasing the user's cleaning time, wasting coffee beans, and bringing a bad user experience. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a bean hopper feeding structure and a coffee grinder containing the same, which can solve the problem that coffee beans often spill from the feed inlet when users take out the bean hopper because they forget to close the bean hopper baffle.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a soybean hopper feeding structure, including a soybean hopper body with a feed inlet, a baffle assembly movably mounted on the soybean hopper body for opening or closing the feed inlet, a main unit with a soybean hopper fixing part, and a linkage mechanism. The linkage mechanism includes a baffle fixing frame mounted on the baffle assembly and a main unit fastener mounted on the soybean hopper fixing part. The soybean hopper body is detachably mounted on the soybean hopper fixing part by rotation. When the soybean hopper body is screwed into the soybean hopper fixing part to the working position, the main unit fastener constrains the baffle fixing frame to fix the baffle assembly relative to the main unit, and at the same time, the soybean hopper body rotates relative to the baffle assembly, opening the feed inlet. When the soybean hopper body rotates in the opposite direction to the removal position, the main unit fastener continues to constrain the baffle fixing frame to rotate in the opposite direction relative to the baffle assembly, closing the feed inlet. At this time, the soybean hopper body can be removed.

[0007] The preferred technical solution of this utility model is that a shielding part is provided at the feed inlet, the bottom of the baffle fixing frame and the bean hopper body are fixedly connected, and the baffle assembly is rotatably connected to the baffle fixing frame.

[0008] The preferred technical solution of this utility model is that a connecting hole is provided on the bottom of the bean hopper body, and a matching connecting post is provided on the baffle assembly. The connecting post passes through the connecting hole and is connected by fasteners, so that the baffle assembly is rotatably connected to the bean hopper body.

[0009] The preferred technical solution of this utility model is that the shielding part has a symmetrical fan-shaped structure, and the baffle of the baffle assembly has a symmetrical fan-shaped structure.

[0010] The preferred technical solution of this utility model is that the main unit fastening includes a first main unit fastening and a second main unit fastening symmetrically arranged on the outer edge of the main unit feeding port. A screw-in area is provided below the first main unit fastening and the second main unit fastening for the bean bin fastening of the bean bin body to be screwed in and fixed.

[0011] The preferred technical solution of this utility model is that an anti-misalignment structure is provided below the second main unit buckle to prevent the bean hopper body from being screwed in in the wrong direction.

[0012] The preferred technical solution of this utility model is that the shielding part has an upward arched structure.

[0013] The preferred technical solution of this utility model is that a bean hopper cover is also provided on the bean hopper body.

[0014] The preferred technical solution of this utility model is that the material of the bean hopper body is a transparent material.

[0015] The present invention provides a coffee grinder, including the bean hopper feeding structure described in the above technical solution.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes a bean hopper feeding structure and a coffee grinder including the same. The bean hopper body is provided with a feeding port and a movable baffle assembly. The baffle assembly is connected to a linkage mechanism through a baffle fixing frame. The main unit is provided with a bean hopper fixing part, and the fixing part has a main unit fastener as a linkage hub. The bean hopper body is installed on the bean hopper fixing part in a detachable screw-in and screw-out manner. When the bean hopper is screwed into the working position (i.e., locked), the main unit fastener constrains the baffle fixing frame, fixing the position of the baffle assembly relative to the main unit, while the bean hopper body continues to rotate relative to it. This relative rotation pulls the baffle open or rotates it to the open position of the feeding port, completing the bean feeding. When the user rotates the bean hopper in the opposite direction to the removal position, the main unit fastener continues to constrain the baffle fixing frame, causing the baffle assembly to rotate in the opposite direction. This causes the feeding port to automatically return to the closed position (the position blocked by the baffle assembly) before the bean hopper is removed from the main unit. Then the bean hopper body can be safely removed, thus solving the problem that users often forget to close the bean hopper baffle when removing the bean hopper, resulting in coffee beans spilling from the feeding port.

Detailed Implementation

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] This embodiment provides a soybean hopper feeding structure, such as... Figure 1-10 As shown, for ease of observation, the accompanying drawings in the instruction manual only show the part of the main unit 3 including the bean hopper fixing part. Figure 3-4 The soybean hopper cover is omitted from the description. The soybean hopper feeding structure includes a soybean hopper body 1 with a feed inlet 11, a baffle assembly 2 movably mounted on the soybean hopper body 1 for opening or closing the feed inlet 11, a main unit 3 with a soybean hopper fixing part 31, and a linkage mechanism. The linkage mechanism includes a baffle fixing frame 41 mounted on the baffle assembly 2 and a main unit fastener 42 mounted on the soybean hopper fixing part 31. The baffle fixing frame 41 is fixedly connected to the bottom of the soybean hopper body 1, and the soybean hopper body 1 is detachable by rotation. The bean hopper is mounted on the bean hopper fixing part 31. When the bean hopper body 1 is screwed into the bean hopper fixing part 31 to the working position, the main unit fastener 42 constrains the baffle fixing frame 41, fixing the baffle assembly 2 relative to the main unit 3. At the same time, the bean hopper body 1 rotates relative to the baffle assembly 2, opening the feed port 11. When the bean hopper body 1 rotates in the opposite direction to the removal position, the main unit fastener 42 continues to constrain the baffle fixing frame 41 to rotate in the opposite direction relative to the baffle assembly 2, closing the feed port 11. At this time, the bean hopper body 1 can be removed. The technical solution of this embodiment rigidly couples the "opening / closing" action of the bean hopper with the installation and removal action of the bean hopper through mechanical linkage, thereby completely avoiding the problem of coffee beans spilling from the feed port when the user forgets to close the baffle when removing the bean hopper. Specifically, the bean hopper body is equipped with a feed inlet and a movable baffle assembly. The baffle assembly is connected to the linkage mechanism via a baffle fixing frame. The main unit has a bean hopper fixing part, and the fixing part has a main unit fastener as a linkage hub. The bean hopper body is installed on the bean hopper fixing part in a detachable screw-in and screw-out manner. When the bean hopper is screwed into the working position (i.e., locked), the main unit fastener constrains the baffle fixing frame, fixing the position of the baffle assembly relative to the main unit, while the bean hopper body continues to rotate relative to it. This relative rotation pulls the baffle open or rotates it to the open position of the feed inlet, completing the bean feeding. When the user rotates the bean hopper in the opposite direction to the removal position, the main unit fastener continues to constrain the baffle fixing frame, causing the baffle assembly to rotate in the opposite direction, so that the feed inlet automatically returns to the closed position (the position blocked by the baffle assembly) before the bean hopper is removed from the main unit. Then the bean hopper body can be safely removed.

[0034] Specifically, a shielding part 12 is provided at the feed inlet 11, and the baffle fixing frame 41 is fixedly connected to the bottom of the bean hopper body 1. The baffle assembly 2 is rotatably connected to the baffle fixing frame 41. Here, the "shielding part" refers to the protrusion or plate located around the feed inlet, which is used to guide and block the flow of particles. It and the baffle assembly together form a double closed interface to ensure that the support point maintains its relative position as the bean hopper moves as a whole.

[0035] Specifically, the bottom of the bean hopper body 1 is provided with a connecting hole 13, and the baffle assembly 2 is provided with a matching connecting post 21. The connecting post 21 passes through the connecting hole 13 and is connected by a fastener 5, so that the baffle assembly 2 is rotatably connected to the bean hopper body 1. This shaft connection provides a clear kinematic pair interface, making the rotation center of the baffle precise, the rotational resistance controllable, and less prone to lateral backlash, thereby ensuring that the baffle can maintain good sealing and positioning even after long-term use; at the same time, the structure is easy to disassemble and repair, the replacement cost of consumable parts is low, and the wear resistance is improved by selecting appropriate materials and surface treatments (such as nickel plating, hardening layer), reducing the risk of bean spillage caused by shaft wear or loose fasteners.

[0036] Preferably, the shielding part 12 has a symmetrical fan-shaped structure, and the baffle 22 of the baffle assembly 2 also has a symmetrical fan-shaped structure. The symmetrical fan-shaped structure design is the preferred structure in terms of geometric fit, force balance, and particle flow control. The symmetrical fan shape ensures that the force exerted by the baffle during opening / closing is evenly distributed on both sides, avoiding jamming or edge leakage caused by uneven loading; the gradual opening of the fan shape allows the particle flow to pass smoothly without instantaneous impact, which helps stabilize the feeding speed and reduce particle rebound and retention; when closed, the overlapping arcs form a sealed circle, creating a good sealing interface, improving overall sealing performance and user experience, while also resulting in a more harmonious and aesthetically pleasing appearance.

[0037] Preferably, the main unit fastener 42 includes a first main unit fastener 421 and a second main unit fastener 422 symmetrically arranged on the outer edge of the main unit 3's discharge port. A screw-in area 423 is provided below the first main unit fastener 421 and the second main unit fastener 422 for the bean hopper fastener 411 of the bean hopper body 1 to be screwed in and fixed. Specifically, the first main unit fastener 421 and the second main unit fastener 422 are left-right symmetrical arc-shaped protrusions formed on the outer edge of the main unit's discharge port. A gap is left between the two arc-shaped protrusions for the bean hopper fastener to pass through when installed downwards. After the user rotates the bean hopper fastener at a certain angle, it enters the screw-in area, thus achieving the engagement of the bean hopper fastener. Furthermore, since the bean hopper fastener is located relatively above the baffle fixing frame, the baffle fixing frame is constrained by the first and second main unit fasteners, ensuring that the baffle assembly remains fixed relative to the main unit during the rotation of the bean hopper body.

[0038] Preferably, a mis-proof structure 424 is also provided below the second main unit latch 422 to prevent incorrect orientation during installation of the bean hopper body 1. Here, "mis-proof structure" refers to any geometric structure that can prevent or indicate incorrect installation, such as keys, stepped holes, one-way bosses, etc. In this embodiment, a protruding structure is added below the second main unit latch to prevent the bean hopper latch from entering the screw-in area in the wrong direction; only the correct orientation can allow it to enter the screw-in area smoothly.

[0039] Preferably, the shielding part 12 has an upward arched structure. "Upward arched structure" refers to the shielding part forming an arched surface of a certain height along its longitudinal direction, with its center higher than both ends. Thin-walled reinforcing ribs can be added inside the arch to improve local rigidity; the surface is smooth to reduce particle retention. This structure guides the beans in the bean bin towards the feed inlet as much as possible, reducing retention near the feed inlet.

[0040] Preferably, the bean hopper body 1 is also provided with a bean hopper cover 6. The bean hopper cover can block the entry of external moisture, dust and odors, delay the oxidation and moisture absorption of coffee beans, thereby reducing the blockage of the feed inlet caused by bean clumping or moisture absorption; in addition, the presence of the cover forms a second layer of protection during the assembly and disassembly of the bean hopper, preventing the beans from leaking out from the top of the bean hopper body.

[0041] Preferably, the material of the bean hopper body 1 is transparent. Choosing a transparent material for the bean hopper body is a preferred solution aimed at improving visual monitoring and user interaction. "Transparent material" typically refers to food-grade engineering plastics such as polycarbonate (PC) or acrylic (PMMA), which possess excellent light transmittance and mechanical strength, while ensuring that the material meets food contact safety standards (e.g., no phthalate additives). Using a transparent material allows users to visually monitor the amount of beans, avoiding overflow or abnormal dispensing caused by overfilling. Transparency also facilitates timely handling of cleaning, inspection of baffle mating surfaces, or discovery of foreign objects, improving maintenance convenience and overall product aesthetics, thus enhancing both functionality and user experience.
