Description

Technical Field

[0001] This application belongs to the field of coffee grinder technology, and particularly relates to a coffee grinder and a coffee powder filtering device. Background Technology

[0002] Existing coffee grinders often produce coffee powder containing a large amount of excessively fine particles. During brewing, these finely ground coffee particles extract significantly faster than those of normal-sized particles, leading to over-extraction of bitter and acidic components, thus affecting the coffee's flavor. Furthermore, when using pour-over coffee makers, excessively fine coffee particles can accumulate on the filter screen or filter paper, obstructing water flow and causing filter clogging, resulting in an unsmooth brewing process and negatively impacting the overall drinking experience.

[0003] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0004] This application provides a coffee grinder and a coffee powder filtering device to solve or alleviate one or more technical problems in the prior art.

[0005] The first aspect of this application provides a coffee grinder, comprising: Grinding assembly for receiving and grinding soybeans; A particle screening component is located below the grinding component. The particle screening component is provided with a plurality of filter holes, which are used to allow soybean powder no larger than itself to pass through. A receiving box, installed below the particle screening assembly, is used to hold soybean powder filtered by the particle screening assembly; The grinding component is detachably mounted above the particle screening component.

[0006] Optionally, the particle screening component has a slot around its periphery, and the grinding component has a protrusion corresponding to the slot, the protrusion being used to be engaged in the slot.

[0007] Optionally, the grinder may further include a handle drive assembly for driving the blades within the grinding assembly to rotate, thereby grinding the beans.

[0008] Optionally, the rotary drive assembly includes a drive handle, which is fixed above the grinding assembly and extends horizontally.

[0009] Optionally, the drive handle includes a curved portion that bends downward in a vertical direction.

[0010] Optionally, the rotary drive assembly further includes a grip portion fixed to one end of the drive handle away from the grinding assembly.

[0011] Optionally, the grinder further includes a fine particle size adjustment component located between the grinding component and the particle screening component, the fine particle size adjustment component being used to adjust the particle size of the ground beans by the grinding component.

[0012] A second aspect of this application provides a soybean flour filtering device, comprising components stacked sequentially from bottom to top: The receiving box has an opening at one end for holding soybean powder; A particle screening assembly is installed at the opening of the receiving box.

[0023] This application provides a coffee grinder and a coffee powder filter. This addresses the problem of coffee powder containing a large amount of excessively fine particles, which negatively impacts the taste of the coffee and disrupts the brewing process. Details are provided below.

[0024] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0025] Please see Figure 1 and with Figure 2 and Figure 3 For further reference, this application provides a coffee grinder, which includes a grinding assembly 10, a particle sorting assembly 20, and a receiving box 30. The following is a detailed description: The grinding assembly 10 is used to receive and grind soybeans. The grinding assembly 10 is detachably mounted above the particle screening assembly 20. In one embodiment, the grinding assembly 10 may include a motor, a drive shaft, and a grinding disc structure. The motor drives the drive shaft to rotate the grinding discs to grind the input soybeans. The spacing of the grinding discs is adjustable to control the fineness of the ground particles, thereby adapting to the particle size requirements of different brewing methods. The housing of the grinding assembly 10 may be made of metal or wear-resistant plastic and is detachably connected to the particle screening assembly 20 via threaded connections or snap-fit ​​structures, facilitating cleaning and maintenance by the user.

[0026] A particle screening component 20 is located below the grinding component 10. The particle screening component 20 has multiple filter holes for passing through soybean powder no larger than itself. In one embodiment, the particle screening component 20 may include a screen structure and a support frame. The screen structure may be made of fine stainless steel mesh, and its aperture range can be set according to different grinding precision requirements, for example, 200~600 micrometers.

[0027] A receiving box 30, installed below the particle screening assembly 20, is used to hold the soybean powder filtered by the particle screening assembly 20. In an optional embodiment, the particle screening assembly 20 has a slot around its periphery, and the grinding assembly 10 has a protrusion corresponding to the slot, the protrusion being used to engage within the slot. The receiving box 30 can be detachably installed below the particle screening assembly 20 by a pull-out design, allowing the user to easily remove it for use after grinding. The receiving box 30 can be made of transparent or semi-transparent material to allow observation of the collected amount. In some embodiments, an anti-static coating can be provided on the bottom of the receiving box 30 to prevent powder from adhering to the inner wall and affecting powder removal.

[0028] In practical applications, after grinding the coffee beans, the grinder can be shaken so that beans larger than the filter holes are retained above the particle screening component 20, while finer beans fall into the receiving box 30, thus separating coarse and fine powder. After grinding, the grinding component 10 can be removed, and the coffee beans retained on the particle screening component 20 can be used for brewing, thereby alleviating the problem of a large amount of overly fine powder mixed in with the coffee powder, which affects the taste of the coffee and makes the brewing process difficult.

[0029] In one optional embodiment, the grinder further includes a handle drive assembly for driving the blades within the grinding assembly 10 to rotate and grind the beans. The user manually drives the handle drive assembly to drive the blades within the grinding assembly 10 to perform cutting and grinding. In some embodiments, the handle drive assembly is also detachable, allowing it to be replaced with a motor drive assembly for different usage scenarios, thereby enabling switching between manual and electric operating modes.

[0030] Specifically, the rotary drive assembly includes a drive handle 41, which is fixed above the grinding assembly 10 and extends horizontally. Preferably, the length of the drive handle 41 can be designed according to torque requirements, specifically from 100mm to 250mm, so that the user can obtain better effort-saving effect when rotating manually.

[0031] Furthermore, in this embodiment, the drive handle 41 includes a curved portion 411, which bends downward in a vertical direction. The curved portion 411 may be located in the middle or at the end of the drive handle 41, forming a downward-extending arc or zigzag structure, making it more ergonomic, allowing the user to rotate more smoothly and effortlessly, and improving the user's operating posture and experience.

[0032] In an optional embodiment, the rotary drive assembly further includes a grip 43, which is fixed to the end of the drive handle 41 away from the grinding assembly 10. Specifically, the grip 43 may be cylindrical, spherical, or elliptical. Preferably, the grip 43 and the drive handle 41 are rotatably connected so that the user can rotate smoothly without changing hand posture during operation, thereby improving comfort. The surface of the grip 43 may have an anti-slip texture or be covered with a rubber layer to prevent slippage and enhance friction.

[0033] In an optional embodiment, the grinder further includes a fine particle size adjustment component 50, located between the grinding component 10 and the particle screening component 20. The fine particle size adjustment component 50 is used to adjust the particle size of the ground beans by the grinding component 10. In a specific embodiment, the fine particle size adjustment component 50 may include an adjustment ring, a limiting structure, and an elastic fitting component. The adjustment ring may be coaxially disposed below the grinding component 10 and connected to the grinding disc spacing. When the user rotates the adjustment ring, it can drive the grinding disc to move slightly in the vertical direction to change the grinding gap, thereby achieving precise control of the bean powder particle size.

[0034] Preferably, the adjusting ring may be provided with scale markings to indicate different grinding fineness levels, so that users can select the appropriate grinding degree according to the brewing method (such as espresso, pour-over or French press).

[0035] Please see Figure 2 and Figure 3 This application also provides a soybean flour filtering device, comprising the following components stacked sequentially from bottom to top: The receiving box 30 has an opening at one end for holding soybean powder.

[0036] The particle screening component 20 is installed at the opening of the receiving box 30. The particle screening component 20 is provided with a plurality of filter holes for allowing soybean powder no larger than itself to pass through.

[0037] The cover 60 is detachably placed on top of the particle screening component 20 and cooperates with the particle screening component 20 to form a soybean flour receiving cavity.

[0038] When the receiving box 30 contains the soybean powder, the soybean powder filtering device is inverted so that some of the soybean powder in the receiving box 30 enters the soybean powder receiving cavity.

[0039] In practical applications, the receiving box 30 contains ground coffee powder. After the lid 60 is placed on the particle screening component 20, the coffee powder filtering device can be inverted to filter out overly fine coffee powder into the lid, thus achieving the filtering effect.

[0040] In addition, the coffee bean filter can also be used with the coffee grinder mentioned above. When the lid 60 is not in use, the lid 60 can be fitted onto the bottom of the receiving box 30. When going out, coffee beans can be placed in the cavity formed by the lid 60 and the receiving box 30 for easy carrying.

[0041] It should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. The directional terms "inner" and "outer" refer to the inside or outside relative to the outline of the component itself. For example, if a device in the drawings is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0042] It should also be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this application refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.

[0043] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0044] It should also be noted that the above are merely preferred embodiments of this application and do not limit the scope of patent protection of this application.
