Description

Technical Field

[0001] This utility model relates to the field of coffee grinder technology, and in particular to a coffee grinder. Background Technology

[0002] A coffee grinder (also known as a coffee grinder) is a device used to grind coffee beans into powder. The design principle of a coffee grinder is to use mechanical force to grind coffee beans into powder. The grinding disc is usually made of metal or ceramic, and its surface is full of fine grooves and teeth. The coffee beans are ground into the required powder by rotating the grinding disc. Some high-end coffee grinders are also equipped with special grinding disc designs to ensure that the ground coffee powder is uniform and fine.

[0003] Existing coffee machines can usually adjust the grind size as needed to meet different coffee preferences. The ground coffee powder is discharged through a powder tube for easy collection, avoiding scattering and environmental pollution caused by waste.

[0004] In actual use, the powder tube is located on the chamber. After the coffee powder is ground, it will be discharged through the powder tube. However, in actual use, coffee powder will inevitably remain in the chamber, which is difficult to clean and causes waste. When the grinder is not used for a long time, the coffee powder remaining inside will affect the quality of the coffee powder ground in the future. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5In one embodiment of this utility model, a coffee grinder is disclosed. Specifically, the grinder includes a combined support 1 and a body 2 mounted on the combined support 1. The combined support 1 has an H-shaped structure, and the body 2 is rotatably connected to the combined support 1 and its rotation position is locked by fasteners such as bolts. Furthermore, in this embodiment, a magnet is also embedded below the middle plate of the combined support 1. The design of this magnet enables magnetic positioning of the collector, thereby improving the convenience and reliability of the collector installation. A grinding assembly is installed inside the machine body 2, and a top cover 3 is installed on the top of the machine body 2. The top cover 3 and the machine body 2 are detachably connected by a fastening assembly. A feeding assembly is also provided on the top of the top cover 3. The machine body 2 has a powder outlet 21 on its side facing the grinding component. A powder outlet component is detachably connected to the outside of the machine body 2 at the powder outlet 21. The powder outlet component is also equipped with a plasma mounting position.

[0021] In some embodiments, the grinding assembly of the present invention includes a grinding chamber 4 fixedly installed in the body 2 by fasteners, and a driving component 5 is fixedly installed inside the body 2. Specifically, the driving component 5 in this embodiment is a motor, which is fixedly installed inside the body 2. Of course, the fasteners in this embodiment can also be bolts. The motor described in this embodiment is a DC brushless inverter motor, which optimizes the traditional problems of high energy consumption and high noise. With the help of ultra-quiet and high power, the grinding temperature can be controlled and reduced to restore the original flavor of different coffee beans.

[0022] The grinding chamber 4 is equipped with a grinding blade assembly, and the drive unit 5 is connected to the grinding blade assembly.

[0023] Specifically, the grinding tool assembly includes a lower tool holder 41 rotatably connected in the grinding chamber 4 and an upper tool holder 42 that slides and is circumferentially locked in the grinding chamber 4; A lower tool holder 43 is fixedly installed above the lower tool holder 41, and an upper tool holder 44 is fixedly installed below the upper tool holder 42. The shaft end of the drive component 5 passes through the lower tool holder 41 and is connected and fixed. A return spring is provided between the upper tool holder 42 and the grinding chamber 4. The return spring is installed below the upper tool holder 42 and is used to realize the backward and upward push reset of the upper tool holder 42. In addition, the circumferential locking in this utility model can be achieved by sliding groove and guide block sliding cooperation, which can prevent the upper tool holder 42 from rotating circumferentially.

[0024] The upper tool holder 42 passes through the middle of the lower tool holder 41. The shaft end of the drive component 5 is connected and fixed to the lower tool holder 41 by a reverse thread screw and a washer. The washer is located above the upper tool holder 42. During disassembly and maintenance, the lower tool holder 41 and the upper tool holder 42 can be disassembled by removing the reverse thread screw and the washer, which greatly improves the convenience of maintenance of the entire grinding tool assembly.

[0025] Based on the above embodiments, in this embodiment, the upper cover 3 is rotatably connected to a toothed disc 31, and the inner side of the toothed disc 31 is threadedly connected to upper and lower threaded sleeves 32. The upper and lower threaded sleeves 32 are circumferentially locked to the inner wall of the upper cover 3, and the upper and lower threaded sleeves 32 abut against the upper part of the grinding blade assembly. A rod 33 is rotatably connected to the side of the upper cover 3, and a drive toothed disc 34 that meshes with the toothed disc 31 is fixedly installed at the end of the rod 33.

[0026] Of course, the toothed disk 31 and the drive toothed disk 34 described in this embodiment adopt a bevel tooth structure design to achieve a vertical transmission design. In specific operation, the above-mentioned rod 33 can be rotated to make it rotate, and the drive toothed disk 34 can be rotated through the rod 33. By means of the meshing transmission relationship between the toothed disk 31 and the drive toothed disk 34, the rotation drive of the toothed disk 31 can be realized. Since the upper and lower threaded sleeves 32 are threadedly connected inside the gear disc 31 and slidably connected to the inner wall of the upper cover 3, the upper and lower threaded sleeves 32 can move up and down when the gear disc 31 rotates, thus abutting against the upper blade holder 42. By controlling the height of the upper blade holder 42, the distance between the upper and lower blade discs can be changed to grind coffee powder of different coarseness. The adjustment method is simple. Of course, in order to intuitively see the adjustment distance of the upper and lower cutter heads, the upper end of the toothed disc 31 in this utility model extends through to the top of the upper cover 3 and is fixedly installed with a scale ring 35. A scale sticker 36 is formed on the top of the upper cover 3 and on the outside of the scale ring 35. The scale ring 35 is provided with indicator points that cooperate with the scale sticker 36. An anti-spinning umbrella cap 37 is also fixedly installed inside the upper and lower screw sleeves 32.

[0027] In this embodiment, the scale ring 35 can be fixed to the upper side of the toothed disc 31 by bolts. When the toothed disc 31 is rotated for adjustment, the scale lines on the scale sticker 36 and the indicator points on the scale ring 35 indicate the grinding coarseness. In addition, this embodiment adopts the design of the anti-jumping bean umbrella cap 37 to avoid the problem of bean jumping during the grinding process. When coffee beans are added, the beans fall directly into the anti-jumping bean umbrella cap 37 and are evenly distributed between the two blades for grinding, which improves grinding efficiency, reduces grinding time, and enhances the stability and reliability of the grinding process.

[0028] In some embodiments, the feeding assembly of this invention passes through the scale ring 35 and through the bean inlet channel 39 of the upper cover 3. An air blowing pipe 310 is fixedly installed at the upper end of the bean inlet channel 39. An air blowing cover 311 is fastened to the port of the air blowing pipe 310. The bean inlet channel 39 is used to add beans during operation. When not in use, the air blowing pipe 310 can be plugged by inserting the air blowing cover 311.

[0029] Furthermore, in this utility model, the fastening assembly includes a plurality of limiting protrusions 38 formed on the bottom of the inner ring of the upper cover 3, and a plurality of slots 45 are provided on the outer side above the grinding chamber 4. The slots 45 are L-shaped, and the limiting protrusions 38 slide and engage in the slots 45.

[0030] Of course, in this embodiment, the multiple slots 45 and the limiting protrusions 38 are vertically opposite each other. During the actual installation, the upper cover 3 is placed on top of the grinding chamber 4, and the limiting protrusions 38 and the slots 45 are aligned and inserted. After insertion, the entire upper cover 3 is rotated until the limiting protrusions 38 slide to the other side of the L-shaped slots 45, thus achieving the vertical limitation of the upper cover 3.

[0031] Based on the above embodiments, the fastening assembly in this embodiment includes a sliding groove formed on the outer wall of the grinding chamber 4, a slider 46 slidably connected inside the sliding groove, an elastic element 47 fixedly connected between the slider 46 and the sliding groove, and a limiting groove 48 on the inner side of the upper cover 3 for locking and engaging with the slider 46.

[0032] Since the upper and lower positions of the upper cover 3 have been limited by the limiting protrusion 38 and the slot 45 in the above embodiment, the upper cover 3 can be circumferentially locked by using the slider 46 and the limiting groove 48 in this embodiment to prevent the upper cover 3 from detaching from the top of the grinding chamber 4 after rotation. In specific operation, after the upper cover 3 is rotated to the correct position, the slider 46 can be moved upward by the pushing force of the elastic element 47 until the upper end of the slider 46 slides and engages with the limiting groove 48 on the inner side of the upper cover 3, thus completing the circumferential locking and fixing of the upper cover 3. Furthermore, the powder dispensing assembly of this utility model includes an inner powder dispensing tube 22 and an outer powder dispensing tube 23 magnetically attached to the powder dispensing port 21. The outer powder dispensing tube 23 is sleeved on the outside of the inner powder dispensing tube 22. The plasma mounting positions are formed on both sides of the inside of the outer powder dispensing tube 23. A metal spring 24 is also installed at the powder dispensing port 21, which is used to generate a vibration effect. Of course, avoidance openings can also be provided at the inner powder dispensing tube 22 and the outer powder dispensing tube 23 to avoid affecting the magnetic connection between the inner powder dispensing tube 22 and the outer powder dispensing tube 23. During the powder discharge process, if there is any residual powder, it can be shaken into the powder receiving container by flicking the spring several times, so that the powder is discharged cleanly.

[0033] Based on the above embodiments, in this embodiment, a plasma block 25 is fixedly installed on the outside of the body 2, and a plasma release line 26 is installed on the plasma block 25. A PCB board 27 and a plasma generator 28 are also installed inside the body 2, and the plasma generator 28 is electrically connected to the PCB board 27.

[0034] Specifically, in this embodiment, the plasma generator 28 is electrically connected to the plasma release line 26, and the electrodes of the plasma release line 26 are electrically connected to the two plasma mounting positions respectively. After the power is turned on, the plasma generator 28 generates positive and negative ions, which are discharged from the powder outlet tube 22. After the positive and negative ions are neutralized, the excess negative ions can effectively eliminate the static electricity of the ground coffee powder, so that the coffee powder does not fly around and the powder is discharged smoothly.

[0035] In summary, during the grinding and powdering process, the powder dispensing component releases plasma, which effectively controls the electrostatic powder flying and adsorption generated during grinding. The powder particles fall directly into the powder receiving container. If there is any residual powder, it can be shaken off into the powder receiving container by tapping the metal spring 24 several times, so that the powder is dispensed cleanly. When cleaning the powder dispensing component, since the powder tube assembly is directly installed to the main body 2 using a magnetic attachment, the powder tube can be directly removed and installed, which is convenient and quick. In addition, the top cover 3 and the grinding chamber 4 are connected by a snap-fit ​​assembly. This structure allows for quick disassembly and assembly without the need for any auxiliary tools, enabling the replacement of universal-specification cutter heads and quick cleaning of the chamber.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
