Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, and in particular to an adjustable angle powder outlet structure and a coffee grinder including the same. Background Technology

[0002] With the increasing popularity of coffee culture in both home and commercial settings, electric coffee grinders, as key equipment in the coffee preparation process, are facing ever-increasing demands in terms of functionality, ease of use, cleanliness, and production efficiency. Current coffee grinders generally include basic components such as a motor, burr (or grinding disc) assembly, bean hopper, powder outlet (or powder outlet tube), and housing and control structure.

[0003] Traditional coffee grinders design the powder outlet at a fixed angle (e.g., vertically downward or slightly tilted) to prioritize simplicity and low manufacturing cost. However, in practical applications with various powder receiving containers (such as those of different heights, diameters, or cup shapes), the fixed-angle design often leads to powder splashing, scattering, or sticking to the container's outer wall when it falls into the container, reducing the powder's hit rate and increasing cleaning workload. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes an adjustable angle powder outlet structure and a coffee grinder containing the structure, which can solve the problem that the powder outlet tube of the current coffee grinder cannot be adapted to the use of various powder receiving containers of different capacities and heights.

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

[0006] This utility model provides an adjustable-angle powder dispensing structure, including a main body, a powder dispensing tube, and an angle adjustment mechanism. One end of the powder dispensing tube is rotatably mounted on the main body, and the angle adjustment mechanism is mounted on the main body. The actuating end of the angle adjustment mechanism drives the powder dispensing tube to rotate and fix relative to the horizontal plane within a predetermined angle range.

[0007] The preferred technical solution of this utility model is that the angle adjustment mechanism includes an adjustment fixing frame fixed on the main body and an adjustment bracket that is movably cooperated with the adjustment fixing frame. One end of the adjustment bracket is in contact with the powder outlet pipe, and the angle adjustment is achieved by the displacement of the bracket relative to the adjustment fixing frame acting on the powder outlet pipe.

[0008] The preferred technical solution of this utility model is that the adjusting bracket is located below the powder outlet pipe, and the adjusting bracket is provided with a support opening that matches the outer contour of the powder outlet pipe for supporting the powder outlet pipe.

[0009] The preferred technical solution of this utility model is that a limiting structure is provided between the adjusting bracket and the adjusting fixing frame, which is used to fix the adjusting bracket in multiple different preset positions.

[0010] The preferred technical solution of this utility model is that the limiting structure includes a gear protrusion on the adjusting bracket and multiple gear grooves on the adjusting fixing frame, wherein the gear protrusion can selectively engage with gear grooves of different heights.

[0011] The preferred technical solution of this utility model is that the adjustment bracket is further provided with a guide rod, and the adjustment fixing frame is provided with a guide groove for the guide rod to slide. The guide rod and the guide groove slide together to guide the movement trajectory of the adjustment bracket.

[0012] The preferred technical solution of this utility model is that the gear shift protrusions are symmetrically arranged on both sides of the adjustment bracket, and the guide rod is located between the gear shift protrusions on both sides.

[0013] The preferred technical solution of this utility model is that the outer side of the adjusting bracket is provided with a protruding plate for applying force.

[0014] The preferred technical solution of this utility model is that the main body is provided with a powder outlet tube fixing frame, and the powder outlet tube fixing frame is provided with symmetrical positioning protrusions on both sides inside. The powder outlet tube is provided with positioning holes at corresponding positions. The sizes of the positioning protrusions and the positioning holes are matched so that the powder outlet tube and the powder outlet tube fixing frame are hinged together.

[0015] This utility model provides a coffee grinder, including the adjustable angle powder outlet structure described in the above technical solution.

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

[0017] This invention proposes an adjustable-angle powder outlet structure and a coffee grinder containing the same. One end of the powder outlet tube is rotatably mounted on the main body and is equipped with an angle adjustment mechanism that drives the powder outlet tube to rotate and fix within a predetermined angle range relative to the horizontal plane. The angle can be manually adjusted by pushing and pulling the powder outlet tube, or precisely adjusted with the aid of a tool via a micro-motion device. It is compatible with various containers, from low cups to tall pots, thereby significantly reducing powder splashing, improving the powder drop hit rate, and facilitating quick adjustment and cleaning maintenance for users. This solves the problem that the powder outlet tubes of current coffee grinders cannot be adapted to various powder receiving containers of different capacities and heights.

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This embodiment provides an adjustable-angle powder dispensing structure, such as... Figure 1-6As shown, the system includes a main body 1, a powder outlet pipe 2, and an angle adjustment mechanism 3. One end of the powder outlet pipe 2 is rotatably mounted on the main body 1. The angle adjustment mechanism 3 is mounted on the main body 1, and its actuating end drives the powder outlet pipe 2 to rotate and fix it relative to the horizontal plane within a predetermined angle range. This solution effectively solves the problem that the powder outlet pipe cannot adapt to various capacity and height powder receiving containers by working together with the main body, the powder outlet pipe, and the angle adjustment mechanism: one end of the powder outlet pipe is rotatably mounted on the main body by pivot or hinge, ensuring that the powder outlet pipe has a reliable bearing and positioning foundation in the radial and axial directions; the angle adjustment mechanism can be composed of a fixed frame and an adjustable bracket that can be guided up and down, realizing the controllable lifting and tilting of the powder outlet end along a predetermined angle range; or the powder outlet pipe can be hinged to the main body through a damping structure to achieve angle adjustment and relative fixation; or even the powder outlet pipe can be electrically driven to adjust the angle. The angle adjustment mechanism of this technical solution can be manually adjusted by pushing and pulling the powder outlet tube, or it can be precisely adjusted with the aid of a tool through a micro-motion device. It is suitable for a variety of containers, from low cups to tall pots, thereby significantly reducing powder splashing, improving the powder drop hit rate, and facilitating quick adjustment and cleaning maintenance for users.

[0031] Preferably, the angle adjustment mechanism 3 includes an adjustment fixing frame 31 fixed to the main body 1 and an adjustment bracket 32 ​​that movably cooperates with the adjustment fixing frame 31. One end of the adjustment bracket 32 ​​contacts the powder outlet pipe 2, and the angle adjustment is achieved by its displacement relative to the adjustment fixing frame 31 acting on the powder outlet pipe 2. This preferred structure clearly separates the load-bearing and guiding functions of angle control: the adjustment fixing frame is fixed to the main body as a base, bearing the operating load and installation tolerances; the adjustment bracket, as a moving part, directly acts on the powder outlet pipe to achieve angle change. This can be achieved by using upper / lower guide grooves with guide pins, or a hinge + guide rail combination, allowing the adjustment bracket to move along a smooth and controllable trajectory; one end of the bracket presses against the outer surface of the powder outlet pipe through a support or contact surface for support or drive. To ensure reliable positioning, an elastic positioning element or stop structure can be integrated between the fixing frame and the bracket to quickly return to its original position and maintain the angle after the operating force is released.

[0032] Preferably, the adjusting bracket 32 ​​is located below the powder outlet pipe 2. The adjusting bracket 32 ​​has a support portion 321 that matches the outer contour of the powder outlet pipe 2 to support the powder outlet pipe 2. In this technical solution, the support portion below the powder outlet pipe can directly support the powder outlet pipe, making the angle adjustment operation smoother. The support portion can be a semi-circular groove or a padded contact surface. The inner lining material can be a wear-resistant plastic (such as POM) to reduce wear, and an installation tolerance (e.g., 0.1–0.5 mm) is allowed to balance assembly convenience and positioning accuracy.

[0033] Preferably, a limiting structure is provided between the adjusting bracket 32 ​​and the adjusting fixing bracket 31 to fix the adjusting bracket 32 ​​in multiple different preset positions. This simple structure achieves rapid and repeatable angle positioning. Specifically: The limiting structure is a component or mechanism used to mechanically lock the bracket at several preset positions; common forms include stops, positioning pins, or toothed grooves. Implementation involves creating a series of vertical stop grooves on the fixing bracket and setting corresponding protrusions or elastic buckles on the adjusting bracket; when the bracket moves to a certain groove position, the protrusion automatically engages and is locked by damping or spring force. This structure can be combined with a micro-slope self-access design to reduce assembly force, and the locking force can be controlled through material selection and geometric fit to ensure no dislodgement under operational vibration. Users can complete angle switching with simple manual actions or a few tools, and each switch results in high powder outlet angle accuracy and good repeatability, significantly improving user experience and reducing process fluctuations caused by adjustments.

[0034] Specifically, the limiting structure of this embodiment includes a stop protrusion 322 on the adjusting bracket 32 ​​and multiple stop grooves 311 on the adjusting fixing frame 31. The stop protrusion 322 can selectively engage with stop grooves 311 of different heights. Here, the stop protrusion is a protrusion on the adjusting bracket used to engage with the stop grooves of the adjusting fixing frame. Preferably, symmetrically arranged protrusion / groove pairs can be used to disperse locking stress and improve anti-overturning ability. Through precise tolerance control (e.g., fit clearance 0.1–0.3 mm) and material elasticity selection (e.g., POM or spring steel), the locking force can resist vibration and is easy to manually release for vertical adjustment. Multiple stop selections meet the requirements of different container heights. The above-mentioned locking mechanism has good anti-loosening properties, and the structure is easy to injection mold or stamp, which is beneficial for industrialization and cost control.

[0035] Preferably, the adjusting bracket 32 ​​is further provided with a guide rod 323, and the adjusting fixing frame 31 is provided with a guide groove 312 for the guide rod 323 to slide. The guide rod 323 and the guide groove 312 slide together to guide the movement trajectory of the adjusting bracket 32. Here, the guide rod is a columnar guide fixed on the adjusting bracket and extending axially; the guide groove is a corresponding elongated hole or groove on the adjusting fixing frame, providing a guide channel for the guide rod. The implementation can be a metal guide post with a plastic guide groove or vice versa, to take into account both wear resistance and lubrication. A lubricant channel or bushing can be added in the guide groove to reduce friction; the shape of the guide groove can be rectangular. This guiding fit significantly improves the linearity and repeatability of the adjusting action, reduces jamming caused by uneven friction or assembly errors, and achieves smooth and non-loose guidance through appropriate clearance design, thereby making the powder outlet angle adjustment more convenient and the positioning more reliable.

[0036] Preferably, the shift protrusions 322 are symmetrically arranged on both sides of the adjusting bracket 32, and the guide rod 323 is located between the shift protrusions 322 on both sides. The above-mentioned symmetrical structure can further improve the stability and positioning accuracy of the structure, enhance the anti-loosening ability when the angle is locked, improve the overall vibration resistance, and facilitate mass production.

[0037] Preferably, the outer side of the adjustment bracket 32 ​​is provided with a protruding plate 324 for applying force. 7. Providing a protruding plate for applying force on the outer side of the adjustment bracket is preferred because it significantly improves ergonomics and ease of adjustment. The protruding plate here is a flat or curved surface protruding from the outer side of the adjustment bracket to allow for hand-held or tool-applied force application. By expanding the grip surface, it reduces the difficulty of operation and the error rate during user adjustment, improves adjustment speed and experience, and facilitates power transmission or remote control in optional mechanical assistance situations (such as in conjunction with a micro motor), enhancing the product's versatility in various application scenarios.

[0038] Preferably, a powder outlet pipe fixing bracket 4 is installed on the main body 1. The powder outlet pipe fixing bracket 4 has symmetrically arranged positioning protrusions 41 on both sides inside. A corresponding positioning hole 21 is provided on the powder outlet pipe 2. The dimensions of the positioning protrusions 41 and the positioning holes 21 match, allowing the powder outlet pipe 2 and the powder outlet pipe fixing bracket 4 to be hinged. Specifically, the powder outlet pipe fixing bracket 4 is provided with an elastic strip 43, which can be deformed outwards by applying appropriate force and return to its original position after the force is applied. The positioning protrusions 41 are located on the inner side of the elastic strip 43. Using the positioning protrusions and positioning holes to achieve the hinge is preferred because it provides a reliable pivot connection and facilitates assembly and positioning. Furthermore, placing the positioning protrusions 41 on the elastic strip 43 makes it easier to install and remove the powder outlet pipe by simply applying force and inserting / removing it. Preferably, the positioning protrusion has a smooth protrusion structure, which makes it easier to insert and install the powder outlet pipe into the powder outlet pipe fixing frame by means of a sleeve. The positioning hole is a corresponding hole on the powder outlet pipe or its bushing. The smooth protrusion structure and the hole form a rotating connection, so that the powder outlet pipe has a controllable rotation axis when adjusted, which facilitates the coordinated work of the support and the adjustment bracket, simplifies the assembly and maintenance of the production line, and facilitates the replacement of standardized parts.

[0039] Furthermore, a positioning groove 22 is provided on the powder outlet pipe 2 and is inserted into and engaged with the positioning plate 42 on the powder outlet pipe fixing bracket 4 to limit the radial position or prevent rotation. This structure effectively constrains the radial and torque while ensuring the degree of freedom of rotation. The positioning plate adopts an insert with a small chamfer, which has a guiding function when inserted and forms a stable fit after assembly. The material can be wear-resistant plastic to balance durability and low noise.

[0040] Example 2

[0041] This embodiment provides a coffee grinder, such as... Figure 7As shown, the grinder includes the adjustable-angle powder dispensing structure of Embodiment 1, and also includes a limiting sleeve 5 to restrict excessive rotation of the powder dispensing tube 2. A powder cup holder 6 is provided below the powder dispensing tube 2 of the grinder to fix the powder cup. The grinder shown in this embodiment further preferably adds a "limiting sleeve" and a "powder cup holder" to the adjustable-angle powder dispensing structure of Embodiment 1 to improve positioning reliability and user adaptability: The "limiting sleeve" refers to the annular protective sleeve fitted around the powder dispensing tube, so that when the powder dispensing tube reaches the preset maximum / minimum tilt angle, the stop surface of the sleeve directly bears the force to prevent excessive rotation of the powder dispensing tube (avoiding overload or misalignment of the hinge); The "powder cup holder" refers to a bracket component installed below the powder dispensing tube with adjustable height and clamping diameter, used to quickly fix powder containers of various capacities and heights and ensure that their center is coaxial with the powder dispensing port.
