For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] Refer to the following Figure 1-Figure 6 A coffee machine grinding bean adjustment ring mounting structure is described according to some embodiments of the present application.

[0027] The coffee machine in the present technical solution has a bean grinding device, including a grinding cylinder 1 and a grinding assembly 2. The grinding assembly is located in a grinding chamber 4 of the grinding cylinder 1. A channel is provided on one side of the grinding cylinder 1. The channel is connected to the bean box outlet of the coffee machine, and the coffee beans enter the grinding chamber 4 from the channel.

[0028] The grinding assembly 2 includes a dynamic grinding wheel 7 and a static grinding wheel 8. The dynamic grinding wheel 7 is connected to the driving device of the coffee machine. The static grinding wheel 8 is placed on a static grinding wheel seat 18. The static grinding wheel seat 18 is arranged at the bottom of the grinding chamber 4. There is a gap between the dynamic grinding wheel 7 and the static grinding wheel 8. The dynamic grinding wheel 7 rotates relative to the static grinding wheel 8 under the drive of the driving device, thereby grinding the coffee beans entering the grinding chamber 4 into coffee powder. The size of the gap between the dynamic grinding wheel 7 and the static grinding wheel 8 determines the coarseness of the ground coffee powder.

[0029] In order to change the gap between the dynamic grinding wheel 7 and the static grinding wheel 8, an adjusting ring 23 is provided on a threaded sleeve of the static grinding wheel 8, wherein the inner wall of the adjusting ring 23 is provided with a thread 26, and the outer wall of the static grinding wheel 8 is provided with a convex tooth 27 corresponding to the thread 26. By rotating the adjusting ring 23, the thread 26 rotates relative to the convex tooth 27, thereby driving the static grinding wheel 8 to move axially, thereby changing the gap between the dynamic grinding wheel 7 and the static grinding wheel 8.

[0030] A first supporting portion is provided on the inner surface of the static grinding wheel seat 18, and a second supporting portion is provided on the top inner surface of the grinding chamber 4. The lower surface of the adjusting ring 23 abuts against the first supporting portion, and the upper surface of the adjusting ring 23 abuts against the second supporting portion. The thread 26 of the adjusting ring 23 cooperates with the convex teeth of the static grinding wheel 8, thereby realizing a stable positioning installation of the upper, lower and both sides of the adjusting ring 23, so that the rotation of the static grinding wheel 8 adjusted by the adjusting ring 23 is stable, thereby realizing accurate and effective adjustment of the gap between the dynamic grinding wheel 7 and the static grinding wheel 8.

[0031] The first supporting part is an open convex ring 34 arranged on the inner surface of the static grinding wheel seat 18 , and the second supporting part is a plurality of supporting blocks 35 arranged circumferentially on the top inner surface of the grinding chamber 4 .

[0032] A sector-shaped guide groove 25 is further provided on the inner surface of the static grinding wheel seat 18 at the opening of the convex ring 34. The guide groove 25 is concentric with the convex ring 34, and the central angle of the sector-shaped guide groove 25 is less than 90°.

[0033] An outer adjustment ring 21 is provided below the static grinding wheel seat 18, and a positioning column 22 is provided on the inner bottom surface of the outer adjustment ring 21. The positioning column 22 passes through the guide groove 25 and extends into the positioning hole 24 at the bottom of the adjustment ring 23. Therefore, the adjustment ring 23 can be driven to rotate by rotating the outer adjustment ring 21. The central angle of the guide groove 25 is less than 90°, which can limit the rotation angle of the positioning column 22, thereby limiting the rotation angle of the adjustment ring 23, so that the gap between the dynamic grinding wheel 7 and the static grinding wheel 8 is controlled within a reasonable range, avoiding the collision and damage of the dynamic grinding wheel 7 and the static grinding wheel 8 caused by too small a gap, and also avoiding the influence of too large a gap on the brewing of coffee powder.

[0034] The bottom of the adjusting ring 23 is provided with an annular tooth surface 28, and the open convex ring 34 is provided with a marble seat 29, and a marble 30 is installed in the marble seat 29, and the marble 30 is in rolling contact with the annular tooth surface 28. Since the static grinding wheel seat 18 is fixed, the rolling contact between the marble 30 and the annular tooth surface 28 can more accurately realize the positioning and maintenance of the adjusting ring 23 during the rotation process.

[0035] When the adjusting ring 23 needs to be cleaned or replaced, the static grinding wheel seat 18 only needs to be removed from the bottom of the grinding chamber 4, and the adjusting ring 23 can be screwed out from the upper part of the static grinding wheel. The disassembly process is convenient and quick.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
