In the embodiment of the utility model, the inner cutter head 12 is an inner conical cutter head with narrow upper part and wide lower part, and the shape of the cleaning brush 221 is conical. In this way, the cleaning brush 221 can better clean the residues adhered to the inner cutter head 12, and the cleaning effect is better.

[0046] In the embodiment of the utility model, the cleaning brush 221 is provided in multiple groups, and the multiple groups of cleaning brushes 221 are annularly arranged on the inner side wall of the cleaning cylinder 22. In this way, the multiple groups of cleaning brushes 221 can improve the cleaning frequency of the inner cutter head 12, thereby further improving the cleaning effect of the inner cutter head 12.

[0047] Referring to Figure 3 and Figure 6 , the cleaning assembly 2 is detachably screwed into the grinding cavity 11 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, the clamping structure includes a sliding groove 213 and a sliding block 14 that are clamped and matched with each other, the sliding groove 213 is formed 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 convex point 2131, and the sliding block 14 is further provided with a concave point 141; in this way, when the mounting seat 21 is screwed into the grinding cavity 11 through the sliding clamping of the sliding groove 213 and the sliding block 14 until the convex point 2131 on the sliding groove 213 is clamped with the concave point 141 on the sliding block 14, the mounting seat 21 is screwed into place at this time.

[0048] Of course, it should be noted that in other embodiments, the positions of the sliding groove 213, the sliding block 14, the convex point 2131 and the concave point 141 can be interchanged, which can also achieve the same technical effect, which is not limited here.

[0049] Further, the machine body 1 is provided with a controller (not shown in the figure) and a sensing element (not shown in the figure) electrically connected with the controller, and the outer side wall of the mounting seat 21 is provided with a trigger block 214, when the mounting seat 21 is screwed into the grinding cavity 11 and is in place, the trigger block 214 can trigger the sensing element, at this time the sensing element sends a signal to the controller, and the controller can judge that the cleaning assembly 2 is assembled in place; then the controller can start the cutter head assembly and the powder sweeping plate 13 to move to realize the cleaning operation, thereby avoiding starting the cutter head assembly when the cleaning assembly 2 is not assembled in place, thereby ensuring the safety of the user.

[0050] In the embodiment, the sensing member is a micro switch, the micro switch 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, and one end of the connecting rod 15 extends out of the avoiding groove 16 to cooperate with the trigger block 214.

[0052] 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 and movable up and down, a limiting block 233 movably arranged in the mounting bracket 231 and movable horizontally, a first elastic member 234 arranged in the mounting bracket 231 and in abutting cooperation with the limiting block 233, and a second elastic member 235 arranged in the mounting bracket 231 and in abutting cooperation with the pressing rod 232; wherein 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 overcome the elastic force of the first elastic member 234 and shrink inwardly along the horizontal direction through the slope.

[0053] In addition, the outer side wall of the cleaning cylinder 22 is provided with two limiting block grooves 223 arranged in an up-down interval, under 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 block groove 223, at this time, the limiting block 233 is clamped into the limiting block groove 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 overcome the elastic force of the first elastic member 234 and shrink inwardly along the horizontal direction through the slope, so that the limiting block 233 is separated from the limiting block groove 223, at this time, the cleaning cylinder 22 can move up and down.

[0054] Under 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 the user, when the user presses the pressing rod 232, the pressing rod 232 can overcome the elastic force of the second elastic member 235 and move, when the user releases the external force, at this time, the pressing rod 232 can rebound and reset under the elastic force of the second elastic member 235.

[0055] 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 cleaning brush 221 in the cleaning cylinder 22 contacts the outer wall of the inner cutter head 12; 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.

[0056] In the embodiment, the first elastic member 234 and the second elastic member 235 are both springs.

[0057] 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.
