Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, and more specifically, to a coffee grinder powder dispensing structure. Background Technology

[0002] A coffee grinder is a specialized device used to grind coffee beans into powders of varying coarseness, widely used in coffee making. Its core function is to break down whole coffee beans into powder suitable for brewing through mechanical grinding—different grind sizes correspond to different coffee brewing methods (e.g., espresso requires very fine grind, pour-over requires medium-coarse grind), directly affecting extraction efficiency and flavor profile. The grinding effect of a coffee grinder depends on its grinding precision (particle uniformity) and adjustability (the ability to precisely control the grind size), making it one of the key pieces of equipment determining coffee quality.

[0003] A coffee grinder's basic structure mainly consists of five core parts: first, the feeding device (such as a hopper) for storing coffee beans to be ground; second, the grinding assembly, which is the core working component, usually consisting of a pair of grinding discs (flat blades, conical blades, etc.) or grinding cores, which cut and grind coffee beans through relative rotation; third, the adjustment mechanism for controlling the spacing between the grinding discs, thereby adjusting the coarseness of the ground powder; fourth, the power system (motor) for providing driving force to the grinding assembly; and fifth, the discharging device (such as a powder hopper or powder outlet) for collecting the ground coffee powder.

[0004] However, existing coffee grinders still have significant limitations in practical use: when the ground coffee powder is discharged through the outlet, it easily clumps and accumulates on the inner wall of the outlet due to its light texture and easy adsorption, resulting in poor powder discharge. In this case, the operator needs to frequently tap the outlet to help the powder discharge, which not only increases the number of steps but may also affect the stability of the equipment due to improper tapping force, thus its overall practicality needs to be improved.

[0005] The existing technology, such as the one with patent number CN202422053179.9 and titled "A Coffee Grinder," also has the above-mentioned problems. Utility Model Content

[0027] Example

[0028] Please refer to Figures 1-4This application provides a powder dispensing structure for a coffee grinder, comprising: a mounting base 1, which has a powder dispensing channel 101, one end of which is a feed inlet for connecting to the hopper of the coffee grinder, and the other end of which is a discharge outlet configured to feed powder to a powder receiving container; an annular shaking cylinder 5, coaxially disposed within the powder dispensing channel 101, and capable of reciprocating between a first position and a second position along the axial direction of the powder dispensing channel 101; and a return spring 10, sleeved on the outer periphery of the annular shaking cylinder 5, with one end elastically engaged with the annular shaking cylinder 5 and the other end elastically engaged with the mounting base 1; wherein, when the return spring 10 is at its natural length, the annular shaking cylinder 5 is in the first position, and when the return spring 10 is in a compressed state, the upper... The annular shaking cylinder 5 is in the second position; and the actuating structure includes: a knob 2, rotatably disposed on the outer wall of the mounting base 1; a first actuating member 6, disposed on the outer wall of the annular shaking cylinder 5 and capable of reciprocating along with the annular shaking cylinder 5; and a second actuating member 8, disposed on the knob 2 and engaged with the first actuating member 6; wherein, when the knob 2 rotates one revolution, the second actuating member 8, in coordination with the first actuating member 6, drives the annular shaking cylinder 5 to complete at least one motion cycle, the motion cycle including: the annular shaking cylinder 5 moving from the first position to the second position to compress the return spring 10, and returning from the second position to the first position under the reset action of the return spring 10.

[0029] In the powder dispensing structure of this application, an annular shaking cylinder 5, which can reciprocate along the axis, is provided in the powder dispensing channel 101. A return spring 10 is sleeved on its outer circumference, and a toggle structure consisting of a knob 2, a first actuating member 6, and a second actuating member 8 is also included. When the knob 2 is rotated, the second actuating member 8 cooperates with the first actuating member 6 to drive the annular shaking cylinder 5 from a first position to a second position to compress the return spring 10. Then, under the action of the return spring 10, it returns to the first position, completing one motion cycle. One rotation of the knob 2 allows the annular shaking cylinder 5 to complete at least one motion cycle. Its advantages are: the reciprocating motion of the annular shaking cylinder 5 can vibrate the inner wall of the powder dispensing channel 101, preventing coffee powder from accumulating and clumping, solving the problem of poor powder dispensing, eliminating the need for manual tapping of the powder outlet, reducing operational steps, avoiding the impact of tapping on equipment stability, and improving practicality.

[0030] In a preferred embodiment, the second actuating member 8 is a toggle wheel, which is coaxially mounted on the knob 2 and has multiple arc-shaped actuating teeth; wherein, the mounting base 1 is provided with a sliding groove 9 adapted to the sliding of the first actuating member 6, the sliding groove 9 extends through to the outer wall of the mounting base 1, the first actuating member 6 extends out of the outer wall of the mounting base 1 through the sliding groove 9 and is adapted to the actuating action of the toggle wheel.

[0031] In the above embodiment, the second actuating element 8 is configured as an actuating wheel with multiple arc-shaped actuating teeth and coaxially mounted on the knob 2. The first actuating element 6 extends out and is adapted to the actuating wheel through the sliding groove 9 of the mounting base 1. The advantages are: the multiple arc-shaped actuating teeth can form a continuous and stable cooperation with the first actuating element 6 during the rotation of the knob 2, ensuring that the annular shaking cylinder 5 can efficiently complete the reciprocating sliding when the knob 2 is rotated; the arc-shaped structure can reduce mechanical wear and jamming during the actuation process and improve the smoothness of transmission; the sliding groove 9 provides a stable sliding guide for the first actuating element 6 and ensures the precise cooperation between the first actuating element 6 and the external actuating wheel. The overall structure is simple and the transmission is reliable, which further enhances the stability and service life of the powder dispensing structure.

[0032] Optionally, the number of the aforementioned arc-shaped actuating teeth is four, so that the annular shaking cylinder 5 can complete four motion cycles within one rotation cycle of the knob 2.

[0033] In a preferred embodiment, the actuating wheel is disposed on the side of the knob 2 facing the mounting base 1, and the outer side wall of the mounting base 1 is provided with a mounting groove 11 for accommodating the actuating wheel.

[0034] In the above embodiments, the mounting groove 11 can enclose and limit the actuation wheel, reducing the contamination of the mating parts of the actuation wheel and the first actuation element 6 by external dust, coffee powder and other impurities, and ensuring the cleanliness of the transmission structure; at the same time, the actuation wheel is embedded in the mounting groove 11, making the connection between the knob 2 and the mounting base 1 more compact, reducing the space occupied by the overall structure, avoiding damage to the actuation wheel by external collisions, and improving the integrity and durability of the structure.

[0035] In a preferred embodiment, a connecting shaft 7 is coaxially provided on the side of the knob 2 facing the mounting base 1, and the connecting shaft 7 is detachably engaged with the mounting base 1.

[0036] In the above embodiments, the detachable structure facilitates the removal of the knob 2 and the connected actuating wheel from the mounting base 1, making it convenient to clean, maintain or replace transmission components such as the actuating wheel and the first actuating element 6, reducing the difficulty of repair when transmission failures are caused by component wear and powder accumulation; at the same time, the coaxially arranged connecting shaft 7 can ensure the coaxiality of the knob 2 when rotating, avoiding the impact of installation offset on the matching accuracy of the actuating wheel and the first actuating element 6, and ensuring transmission stability.

[0037] In a preferred embodiment, the knob 2 is provided with a positioning through hole at its center, and the positioning through hole passes through the actuating wheel.

[0038] The connecting shaft 7 is a bolt, and the bolt's threaded portion passes through the positioning through hole and is threaded into the mounting base 1.

[0039] In the above embodiments, the positioning through hole can form a radial limit on the bolt and the actuating wheel, ensuring the coaxiality of the knob 2, the actuating wheel and the bolt, avoiding deviation during rotation, and ensuring the fitting accuracy of the actuating wheel and the first actuating component 6; the detachability of the bolt connection facilitates the disassembly and assembly of the knob 2 and the actuating wheel, making it convenient to clean or replace parts.

[0041] In the above embodiment, the receiving groove can embed the bolt head into the inside of the knob 2, avoiding the bolt head being exposed and affecting the overall aesthetics, while preventing external collisions from causing the bolt to loosen; the sealing cover 3 seals the receiving groove through threaded engagement, which can prevent coffee powder, dust and other impurities from entering the groove and the bolt connection part, avoiding the accumulation of impurities from affecting the bolt disassembly and assembly or causing the knob 2 to rotate and jam, ensuring the stability of the structure for long-term use.

[0042] As a preferred embodiment, the outer periphery of the knob 2 is provided with anti-slip texture 4.

[0043] In the above embodiment, the outer periphery of the knob 2 is provided with anti-slip texture 4. The advantages are: it can increase the friction between the operator's hand and the knob 2, avoid slippage when rotating the knob 2, and ensure that the operator can stably apply torque to drive the knob 2 to rotate; especially in the scenario where the operator's hand is covered with coffee powder (which is easy to cause slippage), the anti-slip texture 4 can improve the reliability and convenience of operation and ensure the driving effect of the annular shaking cylinder 5.

[0044] In a preferred embodiment, the mounting base 1 further includes a first annular positioning cylinder 102 and a second annular positioning cylinder 103. The first annular positioning cylinder 102 is coaxially disposed within the powder outlet channel 101, and an annular gap is formed between its outer wall and the inner wall of the powder outlet channel 101. The second annular positioning cylinder 103 is coaxially disposed at the discharge end of the powder outlet channel 101, and an annular platform 12 is coaxially disposed on the inner side of the end of the second annular positioning cylinder 103 away from the feed inlet. One end of the annular shaking cylinder 5 is slidably fitted within the annular gap, and the other end extends to the inner side of the second annular positioning cylinder 103. An annular groove is provided on the outer periphery of the annular shaking cylinder 5, and the annular platform 12 extends into the annular groove, forming an installation space together with the annular groove. The reset spring 10 is disposed within the installation space.

[0045] In the above embodiments, the dual positioning structure formed by the first annular positioning cylinder 102 and the second annular positioning cylinder 103 can provide precise guidance for the reciprocating sliding of the annular shaking cylinder 5, preventing radial offset or shaking of the annular shaking cylinder 5 during movement and ensuring movement stability; the annular groove on the outer periphery of the annular shaking cylinder 5 and the annular platform 12 of the second annular positioning cylinder 103 form an installation space and a built-in return spring 10, which can axially limit the return spring 10, preventing the spring from being misaligned or falling off during compression or reset. At the same time, the cooperation between the annular platform 12 and the annular groove limits the maximum sliding stroke of the annular shaking cylinder 5, avoiding excessive movement that could damage the components and improving the reliability of the overall structure.

[0046] In a preferred embodiment, the first annular positioning cylinder 102 and the second annular positioning cylinder 103 are both threadedly engaged with the powder outlet channel 101; wherein, the end of the annular groove away from the outlet penetrates the end face of the annular shaking cylinder 5, and the end of the sliding groove 9 away from the inlet penetrates the outer wall of the mounting base 1.

[0047] In the above embodiment, the first annular positioning cylinder 102 and the second annular positioning cylinder 103 are detachably connected to the powder outlet channel 101 by thread, so that the first annular positioning cylinder 102, the second annular positioning cylinder 103, the annular shaking cylinder 5 (together with the first actuating member 6) and the return spring 10 can be disassembled, which facilitates the inspection or replacement of components such as the annular shaking cylinder 5 and the return spring 10 inside the powder outlet channel 101.
