The coffee machine top cover 2 has a truncated cone groove 22 ; the gear adjustment ring 1 is limited in the truncated cone groove 22 and can rotate in the truncated cone groove 22 .

[0042] The present application is a powder adjusting device for a grinding coffee machine. The powder adjusting device has a simple structure. During the powder adjustment process, there is no need to use a linkage gear method. Instead, the powder adjustment function is achieved by fixing the two sides of the coffee machine top cover 2 up and down through the gear adjustment circle 1 and the powder adjusting connecting cover 3 and directly driving the powder adjusting circle 4 of the grinding bean assembly to rotate, thereby simplifying the entire adjustment assembly and saving time and effort in the powder adjustment process.

[0043] like Figure 1As shown, a sliding rod 31 is provided on one side of the powder mixing connection cover 3 close to the coffee machine top cover 2; the sliding rod 31 is slidably connected in the sliding limit groove 21. When the gear adjustment ring 1 is rotated, the powder mixing connection cover 3 and the gear adjustment ring 1 rotate as a whole relative to the coffee machine top cover 2, and the sliding rod 31 slides along the sliding limit groove 21. The sliding limit groove 21 plays a guiding and limiting role for the sliding rod 31, so that the sliding rod 31 can only slide along the stroke of the sliding limit groove 21. When the powder mixing connection cover 3 and the gear adjustment ring 1 rotate as a whole relative to the coffee machine top cover 2, the powder mixing connection cover 3 drives the powder mixing ring 4 of the grinding bean assembly to rotate, and the powder mixing ring 4 of the grinding bean assembly rotates, thereby realizing the grinding and mixing process.

[0044] like Figure 2 As shown, the sliding limit groove 21 includes a first arc groove 211 and a second arc groove 212; the first arc groove 211 and the second arc groove 212 have the same structure and the same stroke, and the sliding rod 31 includes a first sliding rod and a second sliding rod; the first sliding rod is slidably connected in the first arc groove 211; the second sliding rod is slidably connected in the second arc groove 212. When the gear adjustment ring 1 is rotated, the first sliding rod slides along the first arc groove 211, and the second sliding rod slides along the second arc groove 212. When the powder mixing connection cover 3 and the gear adjustment ring 1 are rotated relative to the coffee machine top cover 2 as a whole, the powder mixing connection cover 3 drives the powder mixing ring 4 of the grinding bean assembly to rotate, and the powder mixing ring 4 of the grinding bean assembly rotates, thereby realizing the grinding and mixing process.

[0045] As a preferred embodiment of the utility model, the first arc groove 211 and the second arc groove 212 are symmetrically arranged; the first sliding rod and the second sliding rod are symmetrically arranged. When the first sliding rod slides along the first arc groove 211 , the second sliding rod slides along the second arc groove 212 .

[0046] As a preferred embodiment of the utility model, the gear adjustment ring 1 is provided with a mounting hole 12, and the mounting hole 12 includes a first mounting hole and a second mounting hole; the first sliding rod is fixedly connected in the first mounting hole; and the second sliding rod is fixedly connected in the second mounting hole, so as to realize the fixed connection between the gear adjustment ring 1 and the powder mixing connection cover 3.
