Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, specifically to a coffee grinder adjustment scale ring. Background Technology

[0002] Coffee grinders have graduated markings on the dial, allowing users to adjust the grind size by rotating the dial. Some grinders also have a reference mark; when the graduated marking aligns with the reference mark, the grinder will operate at the corresponding grind size.

[0003] Currently, coffee grinders have markings on the dial. However, during assembly or use, errors often occur between the numerical markings and the reference markings, leading to inaccurate adjustments to the grind size. Due to this error, users find it difficult to accurately adjust the grind size according to the markings. Inaccurate markings result in coffee powder that is too coarse or too fine, failing to achieve the desired extraction effect and severely impacting the taste and quality of the coffee, thus reducing the precision of the grinding process in coffee making.

[0004] In light of this, we are introducing an adjustable scale ring for coffee grinders. Utility Model Content

[0005] The purpose of this invention is to provide an adjustment scale ring for a coffee grinder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment scale ring for a coffee grinder, comprising: an adjustment ring, a fixing ring, and a copper insert;

[0007] The bottom of the adjustment ring is provided with a scale ring, and the surface of the scale ring is provided with scale lines at equal intervals. The scale lines and the scale ring are integrally formed.

[0008] The graduated ring is fitted onto the surface of the fixed ring, and the surface of the fixed ring is provided with a lower ring circle. The lower ring circle and the fixed ring are integrally formed, and the diameter of the lower ring circle is slightly larger than the diameter of the fixed ring. A step is formed at the joint between the lower ring circle and the fixed ring.

[0009] The copper insert is disposed on the surface of the fixing ring, and a fixing structure is provided inside the copper insert. The copper insert is fixed to the surface of the fixing ring by the screws of the fixing structure to complete the installation.

[0010] Preferably, the fixing structure includes a screw hole between the copper insert and the fixing ring. The screw hole, the copper insert, and the fixing ring are integrally formed. The screw is connected to the bottom of the copper insert. The screw passes through the screw hole inside the copper insert and extends into the interior of the fixing ring to form a fixation. An adjustment structure is provided inside the lower ring circle.

[0011] Preferably, the adjustment structure includes a cylindrical groove inside the lower ring, the cylindrical groove and the lower ring being integrally formed, a spring being connected inside the cylindrical groove, a steel ball being connected to one side of the spring, and axial semi-circular grooves for inserting and aligning the steel balls being equally spaced inside the scale ring, the axial semi-circular grooves facilitating the insertion of the steel balls, and the axial semi-circular grooves and the scale ring being integrally formed.

[0012] Preferably, the inner wall of the scale ring is provided with an inverted step, and the inverted step and the scale ring are integrally formed.

[0013] Preferably, the bottom outer wall of the copper insert is provided with threads, the threads and the copper insert are integrally formed, and the threads are connected to the bean inlet port of the grinder, so the copper insert can move up and down along the threads.

[0014] Preferably, the surface of the adjusting ring is connected to an anti-slip part, which increases the friction and makes it easier for the user to apply force to rotate the adjusting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By rotating the scale ring and the adjustment ring separately, and by the cooperation of the spring and steel ball of the elastic adjustment component with the axial semi-circular groove, the value of the scale ring can be arbitrarily aligned with the marking symbol. This design effectively avoids the error of the scale value, and the user can more accurately adjust the grind fineness according to the type of coffee or personal drinking needs, thus improving the accuracy of the grinding process in coffee making.

[0017] (2) By adjusting the spring and steel ball in the structure and the axial semi-circular groove on the inner wall of the scale ring, the steel ball is embedded in the axial semi-circular groove during the adjustment process, which can effectively prevent the adjustment ring from rotating accidentally, ensuring that the position after adjustment is stable and will not easily change the grinding fineness due to external forces or other factors, thus ensuring the stability and consistency of the coffee grinding process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a coffee grinder adjustment scale ring, including: an adjustment ring 1, a scale ring 2 is provided at the bottom of the adjustment ring 1, and scale lines 15 are provided at equal intervals on the surface of the scale ring 2;

[0024] A fixing ring 3, the scale ring 2 is fitted on the surface of the fixing ring 3, and a lower ring circle 13 is provided on the surface of the fixing ring 3;

[0025] A copper insert 4 is disposed on the surface of a fixing ring 3. The copper insert 4 has a fixing structure inside. The copper insert 4 is fixed to the surface of the fixing ring 3 by screws 7 of the fixing structure to complete the installation.

[0026] The fixing structure includes a screw hole 9 between the copper insert 4 and the fixing ring 3. The screw hole 9, the copper insert 4, and the fixing ring 3 are integrally formed. The screw 7 is connected to the bottom of the copper insert 4. The screw 7 passes through the screw hole 9 inside the copper insert 4 and extends into the interior of the fixing ring 3 to form a fixation. The lower ring circle 13 is provided with an adjustment structure inside.

[0027] The adjustment structure includes a cylindrical groove 8 inside the lower ring 13, which is integrally formed with the lower ring 13. A spring 6 is connected inside the cylindrical groove 8, and a steel ball 5 is connected to one side of the spring 6. An axial semi-circular groove 12 for inserting and aligning the steel ball 5 is provided at equal intervals inside the scale ring 2. The axial semi-circular groove 12 facilitates the insertion of the steel ball 5, and the axial semi-circular groove 12 is integrally formed with the scale ring 2.

[0028] The inner wall of the scale ring 2 is provided with an inverted step 14, and the inverted step 14 and the scale ring 2 are integrally formed.

[0029] The bottom outer wall of the copper insert 4 is provided with a thread 10. The thread 10 and the copper insert 4 are integrally formed and connected to the bean inlet port of the grinder. Therefore, the copper insert 4 can move up and down along the thread 10.

[0030] The surface of the adjustment ring 1 is connected to an anti-slip part 11, which increases the friction and makes it easier for the user to apply force to rotate the adjustment ring 1.

[0031] Specifically, when using the coffee grinder, first place the scale ring 2 on the surface of the lower ring circle 13 of the fixing ring 3. The step 14 on the inner wall of the scale ring 2 engages with the step formed at the joint of the surface of the fixing ring 3, initially fixing the position of the scale ring 2. Next, place the copper insert 4 on the surface of the fixing ring 3. The copper insert 4 and the fixing ring 3 have corresponding screw holes 9. Connect the screw 7 to the bottom of the copper insert 4, so that it passes through the screw hole 9 inside the copper insert 4 and extends into the inside of the fixing ring 3, thereby firmly fixing the copper insert 4 on the fixing ring 3 and completing the installation of the entire adjustment scale ring 2. At this time, the thread 10 on the outer wall of the bottom of the copper insert 4 is used to connect with the bean inlet port of the grinder.

[0032] When it is necessary to adjust the coarseness of the coffee powder, the user can do so by rotating the adjustment ring 1. Since the surface of the adjustment ring 1 is connected to the anti-slip part 11, the friction is increased, making it easier for the user to apply force to rotate the adjustment ring 1. The adjustment ring 1 is relatively independent from the scale ring 2. When the adjustment ring 1 rotates, it will not directly drive the scale ring 2 to rotate. The rotation of the adjustment ring 1 will cause the copper insert 4 connected to it to move on the fixed ring 3. Because the thread 10 on the bottom outer wall of the copper insert 4 is connected to the bean inlet port of the grinder, the copper insert 4 moves up and down along the thread 10.

[0033] During the adjustment process, the adjustment structure inside the lower ring circle 13 of the fixed ring 3 plays a key role. A spring 6 and a steel ball 5 are placed in the cylindrical groove 8 inside the lower ring circle 13. The spring 6 always applies a pushing force to the steel ball 5, so that the steel ball 5 is tightly pressed against the axial semi-circular groove 12 on the inner wall of the scale ring 2. The axial semi-circular grooves 12 distributed at equal intervals on the inner wall of the scale ring 2 allow the steel ball 5 to be precisely inserted and aligned with it at different positions. When the adjustment ring 1 moves the copper insert 4 to the appropriate position, the steel ball 5 will be embedded into the corresponding axial semi-circular groove 12 under the elastic force of the spring 6, realizing the positioning of the adjustment ring 1 and ensuring the stability of the adjustment of the adjustment ring 1. At the same time, the scale lines 15 set at equal intervals on the surface of the scale ring 2 can clearly show the current coarseness setting. By observing the correspondence between the marks on the adjustment ring 1 and the scale lines 15 on the scale ring 2, the user can accurately control the rotation amplitude of the adjustment ring 1, and thus accurately adjust the coarseness of the ground coffee powder.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
