[0039] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0040] 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.

[0041] 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.

[0042] Please see Figures 1-8 This utility model discloses a quick-release grinding disc assembly for a convenient coffee bean grinder, comprising a main body 1, a motor 5, a bean inlet 6, a powder outlet 7, and a grinding chamber 2. The motor 5 is fixedly mounted in the main body 1. One end of the grinding chamber 2 is fixedly connected to the main body 1, and the other end has an opening. The bean inlet 6 and the powder outlet 7 are mounted on the cylindrical surface of the grinding chamber 2 and communicate with the inner cavity of the grinding chamber 2. It also includes a grinding disc assembly 3 controlled by the motor 5, which is detachably connected to the grinding disc assembly along the axial direction of the output shaft of the motor 5. The grinding chamber 2 is equipped with an adjusting pressure ring assembly 4 at its opening for adjusting and locking the grinding disc assembly 3. The adjusting pressure ring assembly 4 is movably connected to the grinding chamber 2. The grinding disc assembly 3 can be completely disassembled to the outside of the grinding chamber 2 along the axial direction of the output shaft of the motor 5, which facilitates the cleaning of residual coffee powder inside the grinding disc assembly 3 and the maintenance of the parts, making the daily maintenance of the coffee grinder more convenient and efficient. When reassembling, the grinding disc assembly 3 can be locked by adjusting the pressure ring assembly 4, and the diameter of the coffee powder ground by the grinding disc assembly 3 can be adjusted.

[0043] The working principle of this utility model is as follows:

[0044] When disassembling and cleaning this product, first rotate the adjusting pressure ring assembly 4 off the grinding chamber 2 to separate it from the grinding chamber 2, allowing the grinding disc assembly 3 to be completely removed. After removing the grinding disc assembly 3, pull out the pins on the fixed grinding disc chamber 31 and the fixed seat 341 to release the axial restriction between them, thus separating the fixed grinding disc chamber 31 and the fixed seat 341. Then, the grinding disc assembly 3 can be directly cleaned and maintained. Subsequent assembly only requires sequential installation, and then aligning and inserting the positioning clip 3412 on the fixed seat 341. The positioning slot 313 of the grinding disc chamber 31 is then fixed by inserting a pin into the pin through hole 312 and the fixing hole. Finally, the threaded seat 342 is threaded to the main body 1 of the machine and the adjusting pressure ring assembly 4 is installed. The bean transfer rod 322 is equipped with a telescopic spring 10. When the adjusting pressure ring assembly 4 is rotated to adjust the tightness, the telescopic spring 10 will be squeezed or stretched, changing the axial position of the bean transfer rod 322, thereby adjusting the axial position of the moving grinding disc 321 and the gap between the moving grinding disc 321 and the fixed grinding disc 311, and changing the coarseness of the coffee powder.

[0045] In this embodiment, the grinding disc assembly 3 includes a fixed grinding disc chamber 31 and a screw-driven movable grinding disc component 32, a bearing movable component 33, and an adjusting thread component 34, which are sequentially axially connected and disposed within the cavity of the fixed grinding disc chamber 31. One end of the screw-driven movable grinding disc component 32 is sleeved on the output shaft of the motor 5. The end of the adjusting thread component 34 away from the bearing movable component 33 is movably connected to the adjusting pressure ring assembly 4. The adjusting pressure ring assembly 4 is used to control the coarseness of the coffee powder ground by the screw-driven movable grinding disc component 32. The axial position of the thread component 34 is adjusted to control the grinding space gap of the screw-driven movable grinding disc component 32. The bearing movable component 33 mainly plays an auxiliary role in rotation, making the rotation of the screw-driven movable grinding disc component 32 and the adjusting thread component 34 smoother.

[0046] In this embodiment, the screw-driven movable grinding disc component 32 includes a fixed grinding disc 311, a movable grinding disc 321, a bean transfer rod 322, and a connecting rod 323, all disposed within the fixed grinding disc chamber 31. The fixed grinding disc 311 is fixedly disposed within the fixed grinding disc chamber 31. The bean transfer rod 322, the connecting rod 323, and the movable grinding disc 321 are sequentially and coaxially fixedly connected and controlled by the output shaft of the motor 5. A telescopic spring 10 is also provided in the inner cavity of the bean transfer rod 322, and a fixed baffle 9 is also provided at one end of the bean transfer rod 322 near the motor 5. The fixed baffle 9 is sleeved on the output shaft of the motor 5. One end of the telescopic spring 10 abuts against the fixed baffle 9, and the other end abuts against the inner wall surface of the bean transfer rod 322. The adjusting pressure ring assembly 4 controls the fixed grinding disc 311 and the movable grinding disc by adjusting the threaded component 34. The gap between 321; wherein, the cylindrical surface of the bean conveying rod 322 is formed with a threaded structure. When coffee beans enter, the bean conveying rod 322 rotates and drives the coffee beans to move towards the moving grinding disc 321 and the fixed grinding disc 311. After the coffee beans are fed into the space between the moving grinding disc 321 and the fixed grinding disc 311, the bean conveying rod 322 also drives the moving grinding disc 321 to rotate, so that the coffee beans are squeezed by the moving grinding disc 321 and the fixed grinding disc 311, and then ground into coffee powder. By adjusting the size of the gap between the moving grinding disc 321 and the fixed grinding disc 311, the coarseness of the ground coffee powder can be adjusted. The ground coffee powder flows out from the gap to the powder outlet 7. The telescopic spring 10 can also reduce the vibration generated by the grinding disc, improve the grinding stability of the coffee grinder and the uniformity of the coffee powder.

[0047] In this embodiment, the adjusting pressure ring assembly 4 includes a scale locking ring 41 and a threaded ring 42, with the scale locking ring 41 fixedly sleeved on the threaded ring 42; the grinding chamber 2 has a threaded structure at one open end, and the threaded ring 42 is threadedly connected to the grinding chamber 2 to limit the movement of the grinding assembly; the adjusting threaded component 34 includes a fixed seat 341 and a threaded seat 342, with the fixed seat 341 sleeved on the threaded seat 342 and threadedly connected, the inner end face of the scale locking ring 41 having a connecting hole 411, and the end face of the threaded seat 342 having a connecting post that engages with the connecting hole 411; a fixed baffle 9 is sleeved on the output shaft of the motor 5, and a telescopic spring 10 is provided inside the screw movable grinding disc component 32, with one end of the telescopic spring 10 abutting against the screw movable grinding disc component 32. The other end abuts against the fixed baffle 9; the scale locking ring 41 controls the axial distance of the threaded seat 342 by rotating through the connecting column, so that the threaded seat 342 squeezes or releases the bearing movable part 33, indirectly controlling the extension or contraction of the telescopic spring 10. The telescopic spring 10 then adjusts the gap between the fixed grinding disc 311 and the moving grinding disc 321. Due to the elasticity of the telescopic spring 10, when the threaded seat 342 changes its own axial distance, the telescopic spring will change the axial position of the bean transfer rod 322 due to the squeezing or moving away of the threaded seat 342, thereby controlling the size of the gap between the moving grinding disc 321 and the fixed grinding disc 311. The fixed baffle 9 plays the role of abutting and blocking, ensuring that the elasticity of the telescopic spring 10 is only released in the direction of the threaded seat 342.

[0048] In this embodiment, the fixed seat 341 is sleeved inside the fixed grinding disc chamber 31. The cylindrical surfaces of the fixed seat 341 and the fixed grinding disc chamber 31 are respectively provided with at least one fixed through hole 3411 and a pin through hole 312 with opposite positions. When the external pin is inserted into the pin through hole 312 of the fixed grinding disc chamber 31 and the fixed through hole 3411 of the fixed seat 341, the axial movement of the fixed grinding disc chamber 31 and the fixed seat 341 is restricted. The fixed grinding disc chamber 31 and the fixed seat 341 are fixedly assembled by inserting the pin into the pin through hole 312 and the fixed through hole 3411 of both. The fixed assembly of the grinding disc assembly 3 is achieved by removing the pin and releasing the fixed fit between the two. Then, the fixed grinding disc chamber 31, the screw movable grinding disc component 32, the bearing movable component 33 and the adjusting thread component 34 are disassembled and separated, realizing a quick-release separation component. This facilitates the cleaning of residual coffee powder inside the grinding disc assembly 3, making the daily maintenance of the coffee grinder more convenient and efficient.

[0049] In this embodiment, the inner wall of the fixed grinding disc chamber 31 is provided with a positioning slot 313, and the outer wall of the fixed seat 341 is provided with a positioning block 3412. The fixed seat 341 is embedded in the fixed grinding disc chamber 31. The rotation between the fixed grinding disc chamber 31 and the fixed seat 341 is restricted by the cooperation of the positioning slot 313 and the positioning block 3412. This can further ensure that the assembly between the fixed grinding disc chamber 31 and the fixed seat 341 is stable and tight, and ensure the overall assembly stability of the grinding disc assembly 3.

[0050] In this embodiment, an abutment ring 421 is formed on the outer wall of the threaded ring 42. The size of the abutment ring 421 is larger than the opening of the main body 1. When the threaded seat 342 is threadedly connected to the main body 1, the abutment ring 421 abuts against the end face of the main body 1. The abutment ring 421 can ensure that when the adjusting pressure ring assembly 4 is locked, it prevents the threaded ring 42 from rotating excessively and disengaging from the threaded structure on the grinding chamber 2, which would cause the screw to jam.

[0051] In this embodiment, the movable bearing 33 includes a movable ring 331, a bearing 332, and a movable bearing 333. One end of the screw movable grinding disc 32 is fitted with the movable ring 331. The end of the movable ring 331 away from the motor 5 extends to form a bearing 332 portion 3311. The bearing 332 is sleeved on the bearing 332 portion 3311, and the movable bearing 333 is sleeved on the bearing 332. At least one connecting block 3413 is formed on the inner wall of the fixed seat 341. The cylindrical surface of the movable ring 331 has a connecting notch 3331 that matches the connecting block 3413. The fixed seat 341 is fixedly connected to the movable ring 331 through the connecting block 3413 and the connecting notch 3331. When the motor 5 starts, the transmission rod 322 drives the connecting rod 323 to rotate. At the same time, the movable ring 331 fitted with the connecting rod 323 is also driven to rotate. The addition of the bearing 332 makes the rotation of the movable ring 331 smoother.

[0052] In this embodiment, the grinding chamber 2 is provided with at least one threaded hole 21 at one end near the motor 5, and the motor 5 is provided with a connecting through hole 51 that is adapted to the threaded hole 21; the external bolt is threadedly connected to the threaded hole 21 through the connecting through hole 51 so that the motor 5 is fixed on the grinding chamber 2.

[0053] In this embodiment, the main body 1 is provided with a control knob 8 that is electrically connected to the motor 5. The control knob 8 is used to adjust the speed of the motor 5.

[0054] The advantages of this utility model are:

[0055] This invention, through its modular quick-release design and intelligent control, not only enables rapid disassembly of the grinding disc assembly, reducing the time cost for users to maintain and clean the product, but also significantly simplifies the cleaning and maintenance process through its integrated detachable structure, making product disassembly easier and more convenient in daily maintenance and cleaning of the grinding disc assembly. At the same time, the coordinated adjustment mechanism of the telescopic spring and motor speed effectively improves grinding stability and coffee powder uniformity, balancing professional-grade grinding precision with ease of use in home settings, thus solving the core pain points of traditional coffee grinders, such as cumbersome maintenance and troublesome disassembly and installation.

[0056] 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.
