[0051] In addition, it should be noted that the grinding device of the utility model is also applicable to a separately arranged bean grinder or other powder grinding device. As long as it involves a powder grinding device, it belongs to the protection scope of the application, which is not limited here.

[0052] Preferably, the first cleaning bristles 221 in the cleaning cylinder 22 are adapted to the shape of the outer wall of the inner cutter head 12. In the embodiment of the utility model, the inner cutter head 12 is an inner conical cutter head with a narrow upper part and a wide lower part, and the first cleaning bristles 221 are conical in shape. In this way, the first cleaning bristles 221 can better clean the residual residues and powder adhered to the inner cutter head 12, and the cleaning effect is better.

[0053] In the embodiment of the utility model, the first cleaning bristles 221 and the second cleaning bristles 241 are provided in multiple groups. The multiple groups of first cleaning bristles 221 are annularly arranged on the inner side wall of the cleaning cylinder 22, and the multiple groups of second cleaning bristles 241 are annularly arranged on the bottom wall of the powder sweeping cylinder 24.

[0054] Referring again to Figures 2-3 and Figure 5 The outer side wall of the powder sweeping cylinder 24 is also provided with at least one group of third cleaning bristles 242 for contacting the inner side wall of the grinding cavity 11. Preferably, the third cleaning bristles 242 are provided in multiple groups, and the multiple groups of third cleaning bristles 242 are annularly arranged on the outer side wall of the powder sweeping cylinder 24.

[0055] Therefore, by arranging the third cleaning bristles 242, when the powder sweeping plate 13 rotates and drives the powder sweeping cylinder 24 to rotate, the third cleaning bristles 242 can sweep a small amount of residual powder adhered to the inner side wall of the grinding cavity 11 to fall to the bottom of the grinding cavity 11, and finally be swept out by the second cleaning bristles 241, thereby ensuring the cleanliness of the grinding cavity 11.

[0056] Further, the powder sweeping cylinder 24 is rotatably arranged on the cleaning cylinder 22 through a clamping structure, which includes an annular clamping groove 224 arranged on the outer side wall of the cleaning cylinder 22 and a plurality of clamping hooks 243 arranged on the top of the powder sweeping cylinder 24, the plurality of clamping hooks 243 are clamped into the annular clamping groove 224 and can rotate along the annular clamping groove 224, thereby realizing the rotational connection between the two.

[0057] Referring to Figure 3 and Figure 6 The cutter cleaning assembly 2 is detachably screwed to the grinding cavity 11 of the machine body 1 through the mounting seat 21; specifically, the mounting seat 21 and the grinding cavity 11 of the machine body 1 are detachably connected through a clamping structure, which includes a sliding groove 213 and a sliding block 14 that are clamped and matched with each other, the sliding groove 213 is arranged on the outer bottom wall of the mounting seat 21, and the sliding block 14 is arranged on the inner side wall of the grinding cavity 11 of the machine body 1, wherein the sliding groove 213 is further provided with a protrusion 2131, and the sliding block 14 is further provided with a recess 141; thus, when the mounting seat 21 is screwed to the grinding cavity 11 through the sliding clamping connection of the sliding groove 213 and the sliding block 14 until the protrusion 2131 on the sliding groove 213 is clamped with the recess 141 on the sliding block 14, the mounting seat 21 is screwed in place at this time.

[0058] Of course, it should be noted that in other embodiments, the positions of the sliding groove 213, the sliding block 14, the protrusion 2131 and the recess 141 can be interchanged, which can also achieve the same technical effect, and are not limited here.

[0059] Further, the machine body 1 is further provided with a controller, a driving device and a sensing element, the driving device drives the powder sweeping plate 13 and the inner cutter 12 to rotate simultaneously; the driving device and the sensing element are electrically connected with the controller.

In this way, the cutter assembly can be started without the cutter cleaning assembly 2 being assembled in place, thereby ensuring the safety of the user.

[0060] In the embodiment, the sensing part is a micro switch, which is in transmission cooperation with the trigger block 214 through the connecting rod 15. The grinding cavity 11 is provided with an avoiding groove 16 for avoiding the trigger block 214. One end of the connecting rod 15 extends out of the avoiding groove 16 to cooperate with the trigger block 214.

[0061] Further, the mounting seat 21 is provided with a through groove 211 and a mounting groove 212 communicated with the through groove 211. The cleaning cylinder 22 is arranged in the through groove 211. The mounting groove 212 is provided with a limiting device 23 for limiting the moving position of the cleaning cylinder 22.

[0062] Specifically, the limiting device 23 comprises a mounting bracket 231 fixed in the mounting groove 212, a pressing rod 232 movably arranged in the mounting bracket 231, a limiting block 233 movably arranged in the mounting bracket 231, a first elastic member 234 arranged in the mounting bracket 231 and abuttingly cooperating with the limiting block 233, and a second elastic member 235 arranged in the mounting bracket 231 and abuttingly cooperating with the pressing rod 232. The limiting block 233 and the pressing rod 232 are in transmission cooperation through a slope. When the pressing rod 232 is driven to move downward, the limiting block 233 can be driven to move inward in the horizontal direction by overcoming the elastic force of the first elastic member 234 through the slope.

[0063] In addition, the outer side wall of the cleaning cylinder 22 is provided with two limiting grooves 223 arranged in an upper and lower interval. Under the action of the elastic force of the first elastic member 234, the limiting block 233 can be driven to horizontally extend out until being aligned with the limiting grooves 223. Then, the limiting block 233 is clamped into the limiting grooves 223 to limit and fix the cleaning cylinder 22. When the pressing rod 232 is driven to move downward, the limiting block 233 can be driven to move inward in the horizontal direction by overcoming the elastic force of the first elastic member 234 through the slope, so that the limiting block 233 is separated from the limiting grooves 223. At this time, the cleaning cylinder 22 can move upward and downward.

[0064] Under the action of the elastic force of the second elastic member 235, one end of the pressing rod 232 can extend out of the mounting bracket 231 for being pressed by a user. When the pressing rod 232 is pressed by the user, the pressing rod 232 can be driven to move by overcoming the elastic force of the second elastic member 235. When the user releases the external force, the pressing rod 232 can be reset by the elastic force of the second elastic member 235.

[0065] Thus, when the pressing rod 232 is pressed and the cleaning cylinder 22 is moved downwards until the limiting block 233 is clamped into the limiting clamping groove 223 at the lower part, at this time, the cleaning cylinder 22 completely covers the outside of the inner cutter head 12, and the first cleaning brush 221 in the cleaning cylinder 22 contacts the outer wall of the inner cutter head 12, at this time, the second cleaning brush 241 on the bottom wall of the powder sweeping cylinder 24 is arranged around the outer periphery of the powder sweeping plate 13, and the second cleaning brush 241 contacts the bottom of the grinding cavity 11; when the pressing rod 232 is pressed and the cleaning cylinder 22 is moved upwards until the limiting block 233 is clamped into the limiting clamping groove 223 at the upper part, at this time, the cleaning cylinder 22 is separated from the inner cutter head 12.

[0066] In the embodiment, the first elastic member 234 and the second elastic member 235 are both springs.

[0067] In addition, the outer side wall of the cleaning cylinder 22 is also provided with a guide sliding groove 222 extending in the height direction, and the two limiting clamping grooves 223 are located in the guide sliding groove 222, and the limiting block 233 is partially clamped into the guide sliding groove 222 and is in sliding clamping cooperation with the guide sliding groove 222.

[0068] Thus, the cleaning cylinder 22 can be moved up and down through the sliding guide cooperation of the guide sliding groove 222 and the limiting block 233, thereby improving the moving stability.
