The first blade disc 210 is provided with a feed port 211 communicating with the grinding gap. Rotating the first blade disc 210 can drive the first blade disc 210 to move toward or away from the second blade disc 220 to adjust the grinding gap. The drive device 300 is disposed on the support 100 and driven to the second blade disc 220. The drive device 300 can drive the second blade disc 220 to adjust the grinding gap. The second cutter head 220 rotates. The adjustment assembly 400 includes a base 410, an adjustment member 420, a transmission structure 430, a locking structure 440, and an elastic member 450. The base 410 is disposed on the support 100. The adjustment member 420 is slidably connected to the base 410. The elastic member 450 is disposed between the support 100 and the adjustment member 420. The transmission structure 430 is disposed between the first cutter head 210 and the adjustment member 420. The locking structure 440 is disposed between the adjustment member 420 and the base 410. The elastic member 450 can drive the adjustment member 420 to slide upward to a first position. In the first position, the locking structure 440 can restrict the rotation of the adjustment member 420. When the adjustment member 420 is driven to slide downward to a second position, the locking structure 440 is released from locking. Rotating the adjustment member 420 can drive the first cutter head 210 to rotate through the transmission structure 430. Users can press the adjusting member 420 to switch between the first and second positions. The elastic member 450 can automatically drive the adjusting member 420 back to the first position and lock it. In the first position, the locking structure 440 can cooperate to lock and restrict the rotation of the adjusting member 420, thereby restricting the rotation of the first cutter head 210. When adjustment is needed, simply press the adjusting member 420 to the second position. At this time, the locking structure 440 is unlocked, and the adjusting member 420 can rotate freely to drive the first cutter head 210 to rotate and adjust the grinding gap. This can avoid wear on the locking structure 440, so that the adjusting component 400 can be used stably for a long time.

[0033] Specifically, the first cutter head 210 and the second cutter head 220 can be configured as annular flat cutter heads, and the driving device 300 can be configured as a drive motor. The motor can be driven to rotate the second cutter head 220 through a gear transmission mechanism. The first cutter head 210 is fixed, thereby enabling relative rotation between the first cutter head 210 and the second cutter head 220 to achieve grinding. The first cutter head 210 is located at the top, the feed port 211 can be located in the middle of the first cutter head 210, and the discharge port 120 can be located on the side of the support 100 and communicate with the grinding gap.

The transmission structure 430 of disc 210 is not limited here. The elastic element 450 drives the adjusting element 420 to remain in the first position. In the first position, the locking structure 440 restricts the rotation of the adjusting element 420, thereby restricting the rotation of the first cutting disc 210 to maintain a stable grinding gap. When adjusting, the user only needs to press the adjusting element 420 to the second position. At this time, the adjusting element 420 can be rotated, and the first cutting disc 210 can be driven to rotate to adjust the grinding gap. It can be understood that a scale can be set on the adjusting element 420. After the adjustment is completed, the user can release the hand, and the elastic element 450 can automatically drive the adjusting element 420 to return to the first position, which is convenient for operation and can also avoid wear of the locking structure 440.

[0034] It is also understandable that the first cutter head 210 and the second cutter head 220 can also be set as conical cutter heads.

The cover plate 520 is installed on the top of the guide trough body 510 to define the discharge guide cavity. The baffle plate 530 is provided at the discharge port 120 and is used to block the powder from being discharged from the discharge port 120. Specifically, the inclined sidewall of the guide trough 510 can guide the powder to discharge downwards, while the cover plate 520 can block the top opening of the guide trough 510 and limit the material guiding cavity. The baffle can block the static electricity flying powder to reduce the random flying of powder and facilitate powder discharge. The detachable cover plate 520 can facilitate the maintenance of the baffle plate 530. After removing the cover plate 520, it is easy to adjust the position of the baffle plate 530 or replace the baffle plate 530, which is convenient for maintenance.

[0042] Reference Figure 3 In some embodiments of this utility model, one end of the baffle 530 is disposed at the top of the discharge port 120, and the other end extends obliquely in a downward direction away from the discharge port 120. Specifically, the baffle 530 can be obliquely disposed at the front of the discharge port 120 to guide the powder downwards for easy powder discharge.

[0043] It is conceivable that the baffle 530 can be made of metal and can be connected to the machine housing. The housing is grounded, and the baffle 530 can discharge the static electricity of the flying powder, which can reduce the powder adsorption in the guide groove due to static electricity and enable precise powder dispensing.

[0044] According to a second aspect embodiment of the present invention, a coffee machine includes a coffee machine employing the above-described grinding assembly. By employing the above-described grinding assembly, the coffee machine can easily adjust the grind size, reduce wear on the locking structure 440, reduce the occurrence of malfunctions, and enable the coffee machine to be used stably for a long time.
