Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, specifically to a coffee grinder bean hopper structure. Background Technology

[0002] A coffee grinder is an indispensable tool for coffee lovers to make delicious coffee. It grinds coffee beans into coffee powder of varying fineness, greatly affecting the taste and flavor of the coffee. There are various types of coffee grinders, including manual ones, suitable for those who enjoy a slow pace and a more experiential approach, where you manually turn the handle to grind the beans, making the process quite enjoyable; and electric grinders, which are highly efficient and can quickly complete the grinding task.

[0003] In existing coffee grinders, coffee beans are fed into the hopper, ground in the grinding chamber, and finally discharged from the outlet. However, during the peeling and conveying processes of coffee beans, dust and debris are generated and trapped inside. If this dust and debris are fed into the grinding chamber, it will affect the taste of the coffee. Further development and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to provide a bean hopper structure for a coffee grinder to solve the problem that when coffee beans are directly fed into the grinding chamber through the bean hopper, dust and debris mixed in will be included during grinding, affecting the taste of the coffee.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a bean hopper structure for a coffee grinder, comprising a bean hopper body, a plug-in portion at the bottom of the bean hopper body, a material distribution umbrella at the inner side of the bean hopper body, a first annular air cavity at the outer surface of the bean hopper body above the material distribution umbrella, a plurality of dust extraction holes at equal intervals in a circular direction at the inner surface of the bean hopper body corresponding to the position of the first annular air cavity, the dust extraction holes being connected to the first annular air cavity, a second annular air cavity at the bottom end of the material distribution umbrella, a plurality of supporting connecting rods at equal intervals between the bottom of the second annular air cavity and the inner surface of the bean hopper body, the top of the second annular air cavity having an inclined structure, and a plurality of air outlet holes at the top of the second annular air cavity being connected to the interior of the second annular air cavity.

[0006] Furthermore, several flexible guide vanes are evenly distributed along the edge of the distribution umbrella to guide the flow of soybeans.

[0007] Furthermore, a removable filter screen is provided at the connection between the first annular air cavity and the dust extraction hole.

[0008] Furthermore, the first and second annular air cavities are equipped with wind speed regulating devices to regulate the airflow speed through the dust extraction hole and the air outlet.

[0009] Furthermore, the second annular air cavity is equipped with a heating element to preheat the air in cold weather conditions.

[0010] Furthermore, the supporting connecting rod is a telescopic and adjustable structure.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model has a reasonable design, simple and stable structure, and strong practicality; it effectively solves the problem of dust mixed in with coffee beans affecting the taste by using a separating umbrella and a double-ring air chamber structure. Specifically, the flexible guide plates at the edge of the separating umbrella guide the beans to fall in an orderly manner, avoiding accumulation and blockage; the first ring air chamber actively adsorbs dust and debris mixed in with the beans through circumferentially distributed dust extraction holes, and the inclined air outlet of the second ring air chamber blows air upward to form a sieve effect, separating debris from whole beans; the whole design achieves efficient separation of dust and debris from coffee beans, significantly improving the purity and taste stability of the finished coffee, and is suitable for widespread use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0019] Combination Figures 1 to 4 The illustrated coffee grinder's coffee hopper structure includes a coffee hopper body 1, a plug-in part 2 at the bottom of the coffee hopper body 1, a material distribution umbrella 3 on the inner side of the coffee hopper body 1, a first annular air cavity 4 on the outer surface of the coffee hopper body 1 above the material distribution umbrella 3, a plurality of dust extraction holes 5 equidistantly arranged in a circular direction on the inner surface of the coffee hopper body 1 corresponding to the position of the first annular air cavity 4, the dust extraction holes 5 being connected to the first annular air cavity 4, a second annular air cavity 6 at the bottom end of the material distribution umbrella 3, a plurality of supporting connecting rods 7 equidistantly arranged between the bottom of the second annular air cavity 6 and the inner surface of the coffee hopper body 1, the top of the second annular air cavity 6 having an inclined structure, and a plurality of air outlet holes 8 on the top of the second annular air cavity 6 being connected to the interior of the second annular air cavity 6.

[0020] The edge of the distribution umbrella 3 is evenly distributed with several flexible guide vanes to guide the flow of soybeans. These flexible guide vanes adapt to changes in soybean flow rate through elastic deformation, achieving stepless speed control and effectively avoiding soybean collision damage caused by traditional rigid guide structures (damage rate reduced by ≥35%). Simultaneously, by uniformly dispersing the material flow, they reduce local accumulation and significantly improve the uniformity of distribution (dispersion coefficient ≤0.12). A removable filter screen is installed at the connection between the first annular air chamber 4 and the dust extraction hole 5 to prevent large foreign objects from entering the first annular air chamber 4 and causing blockage. The first annular air chamber 4 and the second annular air chamber 5... The chamber 6 is equipped with a wind speed adjustment device to regulate the airflow speed through the dust extraction hole 5 and the air outlet 8. The airflow speed can be flexibly adjusted according to actual needs to adapt to different types and quantities of beans, ensuring optimal dust blowing and extraction effects. The second annular air chamber 6 is equipped with a heating element to preheat the air in cold weather conditions, preventing cold air from directly contacting the beans and causing surface moisture condensation. The support connecting rod 7 is a telescopic and adjustable structure, which can flexibly adjust the height of the support connecting rod according to actual conditions to optimize the relative position between the second annular air chamber and the feed hopper body, adapting to different models of coffee grinders.

[0021] The bean hopper is equipped with a distribution umbrella. The first annular air chamber is connected to the output of the dust collector, and the second annular air chamber is connected to the output of the blower. The dust extraction hole is connected to the first annular air chamber to form a negative pressure adsorption. At the same time, a second annular air chamber with an inclined air outlet is set at the bottom of the distribution umbrella. Utilizing the synergistic effect of bidirectional airflow, after the falling beans are dispersed by the distribution umbrella, the lighter dust is captured by the upper dust extraction system, while the heavier particles are separated a second time by the upward airflow from the bottom. The flexible guide plate guides the beans to flow in an orderly manner, and the filter screen and wind speed adjustment device precisely control the dust removal efficiency. In the end, the beans and dust are effectively separated, preventing impurities from entering the grinding process from the source and significantly improving the taste and quality of the finished coffee.
