Referring to fig. 1, a grinding mechanism includes: the grinding device comprises a shell 100, a driving assembly, a spin sealing structure 500 and a locking structure, wherein a grinding device 170 is arranged in the shell 100, and a feed inlet 180 is formed in the shell 100; the drive assembly is coupled to the grinding tool 170 and is capable of driving the grinding tool 170 to rotate relative to the housing 100; the rotary sealing structure 500 is arranged between the driving assembly and the shell 100, the driving assembly can rotationally extend into the shell 100 and seal the feed inlet 180 through the rotary sealing structure 500, the relative angles of the driving assembly and the rotary sealing structure 500 are fixed when the driving assembly seals the feed inlet 180, and the locking structure is arranged between the driving assembly and the rotary sealing structure 500; the locking structure can secure the drive assembly to the housing 100 to reduce or prevent relative play between the two. When the driving assembly rotates to extend into the feeding hole 180, the feeding hole 180 is closed by the rotary sealing structure 500, so that the food in the shell 100 is prevented from falling out of the feeding hole 180 during grinding. Moreover, the locking structure will fix the driving assembly and the housing 100 when the driving assembly achieves the sealing effect of the feed inlet 180, so that the relative angle between the driving assembly and the grinding tool 170 is relatively fixed when the driving assembly contacts the grinding tool 170, and the relative movement between the driving assembly and the grinding tool 170 is reduced or even prevented, so that the driving assembly can be stably and accurately connected with the grinding tool 170.

Specifically, the driving assembly comprises a driving motor (not shown in the figure), and a connecting piece is connected to an output shaft of the driving motor; the grinding tool 170 is connected with a connecting shaft (not shown in the figure), an irregular shaft section is arranged on the connecting shaft, and a groove matched with the irregular shaft section in shape is arranged on the connecting piece; the irregular shaft segments can be inserted into the grooves as the drive assembly is rotated into the housing 100.

In certain embodiments, referring to fig. 2, the drive assembly includes a housing 200, and the spin seal 500 includes an annular step 510 disposed in a middle portion of the housing 200, the annular step 510 being inclined with respect to a cross-section of the housing 200; the casing 100 is provided with an inclined end surface 520 inclined relative to the cross section of the casing, the inclined end surface 520 is parallel to the annular step 510, the feeding port 180 is located on the inclined end surface 520, and the inclined end surface 520 can abut against the annular step 510 and enable the annular step 510 to seal the feeding port 180. When the housing 200 is inserted into the feed opening 180, the annular step 510 will abut against the beveled end surface 520. Since the annular step 510 and the inclined end surface 520 are both inclined, when the angles of the housing 200 and the casing 100 are different, the bottommost end of the annular step 510 cannot abut against the bottommost end of the inclined end surface 520. Then, the gravity of the housing 200 will drive the annular step 510 to rotate, so that the bottommost end of the annular step 510 rotates to the bottommost end of the inclined end surface 520, and the relative positioning of the housing 200 and the housing 100 is completed, so that the driving assembly can be stably and accurately connected with the grinding apparatus 170. In addition, the inlet 180 provided on the inclined end surface 520 has a larger area than the arrangement mode provided on the cross section, so that the efficiency of feeding food materials can be increased.

In some embodiments, referring to fig. 2, the driving assembly includes a housing 200, the locking structure includes a latch 150 and a latch 250, one of the latch 150 and the latch 250 is disposed on the housing 200, and the other is disposed in the housing 100; the part of the housing 200 extends into the housing 100, and the clamping block 150 is slidably clamped in the clamping groove 250. The engagement of the detent 250 and the detent 150 further limits the relative movement between the housing 200 and the housing 100, thereby effectively limiting the angle between the housing 200 and the housing 100, and further ensuring that the drive assembly is stably and accurately coupled to the grinding tool 170.

Specifically, the housing 200 is divided into an upper portion and a lower portion by an annular step 510, the lower portion is projected into the housing 100, and the card slot 250 is located on the housing 200.

The expanding portion 255 allows the latch 150 to slide into the latch groove 250 more easily from the end surface of the housing 200, and directly limits and guides the relative movement between the housing 200 and the case 100 by the limiting portion 253, so that the latch 150 will slide in a rotational direction against the annular step 510 under the guidance of the limiting portion 253, and the housing 200 and the case 100 are relatively positioned and fixed.

It is envisioned that the clamping groove 250 may be located in the feeding hole 180, and the clamping block 150 is disposed on a side wall of the clamping groove 250. The specific embodiments may be adjusted accordingly according to the actual situation, and are not limited herein.
