Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] This utility model embodiment discloses a quick-release device for a coffee grinder, such as... Figure 1-10 As shown, it includes: an adjusting plate 1, an adjusting cam 2, a fixed plate 3 and a base 4. The fixed plate 3 is sleeved on the outer wall of the base 4. The base 4 is internally threaded with an adjusting shaft 5 that is fixedly connected to the adjusting cam 2. The base 4 is sleeved with a first bearing 6. The end of the adjusting shaft 5 away from the adjusting cam 2 is sleeved with a second bearing 7.

[0036] The adjusting disc 1 and the adjusting cam 2 are detachably connected. The adjusting disc 1 is used to drive the adjusting cam 2 to rotate so that the adjusting shaft 5 can adjust the distance between the grinder blades. The fixing disc 3 is used to be threaded onto the grinder.

[0037] It should be noted that the adjusting plate 1 and the adjusting cam 2 are detachably connected. Since the fixed plate 3 is threaded onto the coffee grinder, it provides a quick-release device for the coffee grinder, which facilitates quick disassembly and assembly, thereby making it convenient to clean the coffee grinder and replace the blades.

[0038] like Figure 1-5 As shown, one end of the adjusting shaft 5 relative to the second bearing 7 is inserted into the moving cutter head module 400, and a fixing screw 8 threadedly connected to the adjusting shaft 5 is embedded on the adjusting cam 2. It should be noted that the fixing screw 8 facilitates the fixed connection between the adjusting cam 2 and the adjusting shaft 5; the rotation of the adjusting disc 1 drives the adjusting cam 2 to rotate. Since the adjusting cam 2 is fixedly connected to the adjusting shaft 5, the adjusting cam 2 drives the adjusting shaft 5 to rotate, thereby adjusting the distance between the cutter heads.

[0039] like Figure 1-5 As shown, the base 4 is provided with a positioning boss 41 that contacts the first bearing 6. It should be noted that the positioning boss 41 is used to position and install the first bearing 6.

[0040] like Figure 3 and Figure 4 As shown, the adjusting disc 1 has ribs 11 inside, and the outer wall of the adjusting cam 2 has several slots 21 evenly distributed along its circumference. The ribs 11 are inserted into the slots 21. It should be noted that, due to the insertion and engagement of the ribs 11 and the slots 21, the adjusting disc 1 can smoothly drive the adjusting cam 2 to rotate.

[0041] like Figure 3 and Figure 4 As shown, the outer wall of the adjusting plate 1 is provided with protrusions 12, and the base 4 is provided with straight grooves 42 and annular grooves 43 that are interconnected. It should be noted that the protrusions 12 of the adjusting plate 1 pass through the straight grooves 42 and enter the annular grooves 43, so that the adjusting plate 1 and the base 4 are rotated and limited; due to the insertion and cooperation of the ribs 11 and the slots 21, the adjusting plate 1 can smoothly drive the adjusting protrusions 2 to rotate.

[0042] like Figure 3 and Figure 4 As shown, there are two protrusions 12 and two straight grooves 42. It should be noted that, since there are two protrusions 12 and two straight grooves 42, the adjustment disk 1 can be rotated and limited. The two protrusions 12 can be symmetrically distributed or asymmetrically distributed. The number of protrusions 12 can also be set to multiple. The one-to-one correspondence between the protrusions 12 and the straight grooves 42 ensures that the adjustment disk 1 can only be taken out from the base 4 in the preset direction.

[0043] like Figure 6-10 As shown, the adjusting disc 1 has a built-in magnet 9, and the adjusting cam 2 is made of magnetic material; or, the adjusting disc 1 is made of magnetic material, and the adjusting cam 2 has a built-in magnetic block. It should be noted that the adjusting disc 1 and the adjusting cam 2 are magnetically connected, which facilitates quick assembly and disassembly of the adjusting disc 1.

[0044] like Figure 8 and Figure 9 As shown, the adjustment plate 1 has an installation slot, and the magnet 9 is fixedly installed in the installation slot.

[0045] like Figure 8 and Figure 9 As shown, the outer wall of the adjusting cam 2 has a groove 22. It should be noted that the quick-release mechanism can be configured with markings on the base 4 and alignment lines on the adjusting disc 1; or markings can be made on the adjusting disc 1 and graduation lines on the base 4. The groove 22 allows the user to easily rotate the adjusting cam 2, enabling the quick-release device to return to zero quickly.

[0046] For example, when zeroing, first, align the scale line on the adjustment disc 1 with the 0 position on the base 4; second, remove the adjustment disc 1 along the axial direction to disengage it from the quick-release device; then, hold the groove 22 and rotate the adjustment cam 2 until any desired cutter head spacing or zero point is reached (the definition of zero point is: the cutter head moves back 1-2 marks after cutting); finally, align the protrusion 12 of the adjustment disc 1 with the straight groove 42 of the base 4, and install the adjustment disc 1 along the axial direction so that the protrusion 12 of the adjustment disc 1 enters the annular groove 43 of the base 4. During assembly, the rib 11 of the adjustment disc 1 will engage with the slot 21 of the adjustment cam 2, thus completing the zeroing operation.

[0047] like Figure 1-10 As shown, the first bearing 6 is fixedly sleeved with the base 4, and the second bearing 7 is fixedly sleeved with the adjusting shaft 5. It should be noted that, because the first bearing 6 is fixedly sleeved with the base 4 and the second bearing 7 is fixedly sleeved with the adjusting shaft 5, axial rotation of the first bearing 6 relative to the base 4 and axial rotation of the second bearing 7 relative to the adjusting shaft 5 can be prevented.

[0048] For example, the assembly process of the quick-release device of the first type of coffee grinder is as follows:

[0049] First, the first bearing 6 is assembled onto the outer ring of the base 4 by strong pressure. The first bearing 6 is positioned by the positioning boss 41 on the outer side of the base 4. The assembly of the first bearing 6 and the base 4 can also be done by applying glue, snap rings, etc., so that there is no relative movement between the first bearing 6 and the inner ring of the base 4 in the axial direction. Then, the fixing plate 3 is assembled onto the outer ring of the first bearing 6 by strong pressure, glue, snap rings, etc., so that there is no relative movement between the fixing plate 3 and the outer ring of the first bearing 6 in the axial direction.

[0050] Next, the second bearing 7 is fixed to the adjusting screw by force or by applying adhesive. Then, the adjusting screw (along with the second bearing 7) is installed into the screw hole in the center of the base 4, and the adjusting cam 2 is installed onto the adjusting screw. Finally, the adjusting cam 2 and the adjusting screw are locked together as a single unit using screws. Finally, the protrusion 12 of the adjusting disc 1 is aligned with the straight groove 42 of the base 4, and the adjusting disc 1 is installed axially until the protrusion 12 of the adjusting disc 1 enters the annular groove 43 of the base 4. During assembly, the ribs 11 of the adjusting disc 1 will engage with the slots 21 of the adjusting cam 2.

[0051] After the quick-release device is assembled, it can be installed on the coffee grinder. During installation, hold the fixing plate 3 with your hand, bring the quick-release device close to the coffee grinder body, and rotate it at a certain angle so that the base 4 is engaged with the positioning pin on the coffee grinder. You can feel the quick-release device moving along the axial direction to complete the positioning. Then rotate the fixing plate 3 so that the threads on the fixing plate 3 engage with the threads on the coffee grinder until it is tightened.

[0052] Working principle: The adjusting plate 1 and the adjusting cam 2 are detachably connected. Since the fixed plate 3 is threaded onto the grinder, it provides a quick-release device for the grinder, which facilitates quick disassembly and assembly, and makes it easy to clean the grinder and replace the blades.

[0053] Coffee grinder working principle: Coffee beans fall from the bean hopper 100 into the grinding chamber 200. When the machine is started, the grinding motor 300 drives the moving blade module 400 to rotate. The moving blade module 400 and the fixed blade 401 fixed on the grinding chamber 200 form relative motion, thereby achieving the grinding effect. After grinding, the coffee powder falls into the powder receiving cup 600 through the powder outlet 500.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
