Description

Technical Field

[0001] This utility model relates to the field of hand-cranked coffee grinders, and more particularly to a quick-release hand-cranked coffee grinder housing with a high grip structure. Background Technology

[0002] A hand-cranked coffee grinder is a manually operated coffee grinding tool that grinds coffee beans using mechanical principles. It is practical, classic, and preserves the original flavor and aroma of the coffee beans. When the grinder is manually rotated, the grinding discs begin to turn and, relying on internal pressure, adhere tightly to the coffee beans, applying downward force to compress and grind them. The coffee grounds are then collected by the screw into the coffee grounds collector. This grinding method is natural and stable, better preserving the flavor and aroma of the coffee beans. Hand-cranked coffee grinders are small, lightweight, and portable, making them ideal for travel, camping, and outdoor activities. They do not rely on electricity and can be used anywhere, increasing flexibility and convenience. Compared to electric grinders, hand-cranked coffee grinders are generally more affordable, suitable for consumers with limited budgets.

[0003] In existing technology, hand-cranked coffee grinders generally include a detachable first outer cylinder and a second outer cylinder. Corresponding structures are installed inside the cylinders, with one outer cylinder serving as a collection chamber for the ground coffee powder and the other housing a grinding disc assembly to form a grinding chamber. However, in practical use, the following shortcomings exist: Since both the first and second outer cylinders are circular, additional structures such as silicone sleeves are typically required to ensure proper stress distribution during grinding. Furthermore, due to the frequent need to empty the coffee powder, the detachable structure between the first and second outer cylinders needs to be used frequently. Conventional threaded structures require complex steps and are time-consuming to disassemble. Therefore, a more rationally designed solution is urgently needed to address the shortcomings and drawbacks of the existing technology. Utility Model Content

[0004] In view of the technical problems of existing hand-cranked coffee grinders, the outer cylinder is a simple cylindrical structure which leads to poor grip and the disassembly of the outer cylinder is not convenient, this utility model provides a solution.

[0028] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0029] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0030] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0031] To address the aforementioned technical problems, this application provides a quick-release hand-cranked coffee grinder housing with a high grip structure. Please refer to the attached document. Figure 1 To be continued Figure 6 The device includes a first housing 1 and a second housing 2. The first housing 1 has a polygonal cross-sectional profile and a powder storage compartment 11 is formed inside. The second housing 2 has a polygonal cross-sectional profile that matches the cross-sectional profile of the first housing 1 and a grinding compartment for assembling the grinding assembly is formed inside. The first housing 1 and the second housing 2 are detachably connected. In the locked assembly state, the first housing 1 and the second housing 2 together form a flush profile surface.

[0032] The following describes the solution of this application in conjunction with specific implementation methods: First, as those skilled in the art know, in use, this application requires the corresponding installation of a grinding assembly inside the second housing 2, and is connected to one of the grinding blades in the grinding assembly via a rocker arm. During use, the user holds the first housing 1 and the second housing 2 in their locked state with one hand, while driving the rocker arm with the other. Due to its polygonal profile design, the user can easily achieve the grinding action without slipping. Specifically, by rotating the rocker arm to drive the grinding blade to rotate, the grinding blade and the other grinding blade generate relative motion, thereby enabling the coffee beans between the two grinding blades to be ground until processed into coffee powder of the desired particle size. Coffee powder flows from the powder outlet at the end of the second housing 2 into the powder storage compartment 11 of the first housing 1. After grinding, the user releases the lock between the first housing 1 and the second housing 2, allowing the powder storage compartment 11 in the first housing 1 to be exposed. This enables the ground coffee powder to be introduced into a specific component in a fixture, such as a moka pot, pour-over kettle, or espresso machine. The locking structure can be a screw, snap-fit, pin, or magnetic lock. It can be seen that designing the first housing 1 and the second housing 2 into a polygonal shape allows for greater force exertion through the polygonal edges during disassembly and assembly, eliminating the need for additional force structures such as silicone rings or stripes, thus greatly simplifying the structure.

[0033] As a specific implementation scheme, the polygon has at least 4 sides. It's easy to understand why a triangular shape isn't used instead of a polygon with 3 sides; while a triangular shape can generate good grip, it's difficult for the user to achieve a full-body fit, leading to discomfort and a reduced user experience. Having at least 4 sides provides a better grip. In a further embodiment, the polygon preferably has 4 sides. The second housing 2 also has a locking ring 21 on its end face, the diameter of which is smaller than the minimum width of the second housing 2. The outer ring of the locking ring 21 has flanges 22 corresponding to the straight surfaces of the second housing 2. The inner wall of the first housing 1 forms an active area 12 at the corners for the flanges 22 to slide in or out. The surface area is provided with a snap-fit ​​groove 13; in the locked assembly state, the flange 22 is fitted into the snap-fit ​​groove 13; during use, the user holds the first housing 1 with one hand and the second housing 2 with the other hand. At this time, the four sides of the second housing 2 are aligned with the four corners of the first housing 1, and the flange 22 can slide into the expected position through the movable area 12. The first housing 1 and the second housing 2 are rotated relative to each other by external force, and the flange 22 rotates accordingly to the snap-fit ​​groove 13, thereby achieving the locking between the first housing 1 and the second housing 2. The first housing 1 and the second housing 2 form a complete and smooth outer wall surface, and there will be no misalignment; with the cooperation of the movable area 12 and the snap-fit ​​groove 13, the assembly of the first housing 1 and the second housing 2 is simpler and more convenient.

[0034] In a specific embodiment, the first housing 1 has a first step 14 formed according to its inner wall contour. The platform of the first step 14 forms a notch that exposes the locking area. The locking area is located at the position of the first step 14 corresponding to the straight surface of the first housing 1. It also includes a top ring 18, which is fixed to the platform of the first step so that the locking area forms a snap-fit ​​groove 13. The top ring can be assembled on the first step by a suitable screw structure or plug-in structure. The first step and the top ring cooperate to form the snap-fit ​​groove 13. This solution is relatively simple and can greatly reduce the processing difficulty. In a further embodiment, the bottom of the snap-fit ​​groove 13 (also the locking area) 13 is an arc surface. The wall thickness formed by the arc surface gradually decreases in the locking direction. The side of the flange 22 that contacts the locking area 13 is a curved surface. The setting of the curved surface and the arc surface can play a good guiding sliding effect, so that the flange 22 can move well in the locking area.

[0035] In a further embodiment, a second step 16 is formed on the side of the locking area away from the notch 15, and the platform of the second step 16 is provided with a locking recess 17; the flange 22 is also provided with a locking ball 23 on the side near the first housing 1; in the locked assembly state, the locking ball 23 partially extends into the locking recess 17; through the mutual cooperation of the locking ball 23 and the locking recess 17, the locking ball 23 is always in contact with the second step 16 during the process. When the user rotates the first housing 1 and the second housing 2 to the locked position, the locking ball 23 extends into the locking recess 17 and generates corresponding vibration and sound feedback, so that the user can know whether the expected locked position has been reached; on the other hand, the locking ball 23 and the locking recess 17 can also play a mutual locking role, avoiding the situation where the first housing 1 and the second housing 2 become relatively loose.

[0036] In this embodiment, the side of the locking ring 21 away from the second housing 2 is also provided with an assembly ring 24, which is used to fix or assemble the grinding assembly; in a further embodiment, the assembly ring 24 and the locking ring 21 are connected by a threaded structure.

[0037] In this embodiment, the second housing 2 is also provided with a middle cylinder 27 fixed by a fixing arm 25, and a bean drop channel 26 connecting the grinding chamber is formed between any two adjacent fixing arms 25; the middle cylinder 27 is used for the extension of the force end of the rocker arm; in order to fully demonstrate the portability of the hand-cranked coffee grinder, the hand-crank arm is generally detachable and installable. In this case, the installation of the hand-crank arm and the coaxial driving function are realized through the middle cylinder 27.

[0038] In this embodiment, the edges of both the first housing 1 and the second housing 2 are provided with chamfers 3, which reduces the harm to the user from the edges when the user exerts force to grip, and the design of the chamfers 3 will not significantly reduce the grip force, which is more in line with the solution of this application.

[0039] The advantages of this utility model are:

[0040] By designing the first and second housings into polygonal shapes, greater force can be generated by the edges of the polygons during disassembly and assembly, eliminating the need for additional force-bearing structures such as silicone rings or stripes, thus greatly simplifying the structure.

[0041] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
