Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 3, it is the structural schematic diagram of the kitchen waste smashing device provided by the utility model. Kitchen garbage reducing mechanism includes a base 10, and one sets up grinding ring 20 on the base 10 to and one wears to establish strike hammer mechanism 30 in the grinding ring 20. It is contemplated that the kitchen waste shredder may further include other functional modules, such as an assembly module, a bin for receiving shredded material pieces, a bracket for supporting the base 10, a driving device for driving the hammer mechanism 30 to rotate, an electrical connection module, a control module, etc., which are well known to those skilled in the art and will not be described in detail herein.

The base 10 includes a sleeve 11, an inlet port 12 provided at one side of the sleeve 11, and an outlet port 13 provided at the other side of the sleeve 12. The sleeve 11 is cylindrical and is used for accommodating and fixing the grinding ring 20. Feed inlet 12 with discharge gate 13 is followed plumb line sets up to can be under the effect of gravity, kitchen garbage directly follows fall into in the feed inlet 12 among the grinding ring 20, and the rubbish after smashing can be followed automatically discharge gate 13 falls out. The sleeve 11 is provided with an opening 112 at one axial end thereof and a bearing hole 111 at the other axial end thereof. The grind ring 20 is inserted into the grind ring 20 through the opening 112, and it is contemplated that the opening 111 may also be provided with an end cap (not shown). The hammer mechanism 30 is provided in the bearing hole 111, and it is conceivable that a bearing or the like is provided in the bearing hole 111.

The grinding ring 20 is fixed in the sleeve 11 and one of the grinding rings 20 is radially parallel to the vertical line. The grinding ring 20 comprises a body 21, a plurality of discharge slots 22 arranged in the body 21, and two crushing slot groups 23 arranged on both sides of the discharge slots 22. The body 21 is annular and may be made of metal, and is fixed in the sleeve 11. The discharge slot holes 22 are provided with a plurality of holes and correspond to the discharge holes 13. The width of the discharge slot 22 determines how large the particle size of the crushed waste can fall out. In this embodiment, the grinding ring 20 has 5 discharge slots 22 and is arranged along the circumference of the body 21. And each of said discharge slots 22 extends in the axial direction of said body 21. Since the discharge slot 22 corresponds to the discharge hole 13, the discharge slot 22 is also disposed on the vertical line, specifically, the discharge slot 22 is disposed on the side facing the base along the vertical line.

The two comminution groove groups 23 can have the same structure and are located on both sides of the discharge slot 22. Each pulverizing groove group 23 includes a plurality of pulverizing grooves 231. A plurality of the pulverizing grooves 231 are provided at intervals. The contour line of the pulverizing groove 231 in a cross section perpendicular to the axial direction of the grinding ring 20 includes a straight line 232 and an arc line 233 connected to the straight line 232. The grinding groove 231 is formed by cutting the contour line of the grinding groove 231 in the axial direction of the grinding ring 22. The straight line 232 coincides with the radial direction of the grinding ring 20. The arc 233 is an arc whose center is not coincident with the center of the grinding ring 20, and the included angle between the diameter of the arc and the vertical line is an acute angle. On one side of the discharge slot 22 the arc 233 is between the straight line 232 and the discharge slot 22, and on the other side of the discharge slot 22 the straight line 232 is between the arc 233 and the discharge slot 22. On the axial section perpendicular to grind ring 22 the biggest central angle that crushing groove 231 of ejection of compact slotted hole 22 both sides has is greater than 180 degrees to make with on the inside wall of grind ring 20 adjacent with feed inlet 12 need not set up crushing groove 231, because can not reach in the effect of gravity kitchen garbage discharge port 12 side.

The grinding ring 20 further comprises at least one guide groove 24 disposed on the body 21, wherein the guide groove 24 is disposed on an inner side wall of the body 21, is opened along a circumferential direction, and is disposed on a side facing the opening. The guide groove 24 helps the kitchen waste to flow along the inner side wall of the grinding ring 20, so that the grinding efficiency can be improved.

The striking hammer mechanism 30 includes a bearing 31, at least two fixed disks 32 fixedly disposed on the bearing 31, and at least two striking hammers 33 disposed on the fixed disks 32. The bearing 31 is inserted and fixed in the bearing hole 111. The fixed disk 32 is fixed on the bearing 31 and is accommodated in the grinding ring 20. The fixed disk 32 is disposed in the middle of the grinding ring 20 in the axial direction thereof, so that the two striking hammers 33 are disposed on both sides of the fixed disk 32 in the axial direction thereof, respectively. The striking hammer 33 extends towards the center of the grinding ring 20 to form a certain cross section, so that the striking hammer 33 can rotate to push against and crush the kitchen waste. In the present embodiment, the striking hammers 33 have three. The maximum diameter between the at least two striking hammers 33 corresponds to the inner diameter of the grinding ring 20 to grind the ground garbage together with the grinding groove 231.

Compared with the prior art, the utility model provides a kitchen garbage reducing mechanism is owing to have grind ring 20, through the innovative design to this grind ring 20, grind ring 20 promptly and include a plurality of settings and be in ejection of compact slotted hole 22 on the body 21, and two settings are in the crushing bank of cells 23 of ejection of compact slotted hole 22 both sides. The contour line of the pulverizing groove 231 in a cross section perpendicular to the axial direction of the grinding ring 20 includes a straight line 232 and an arc line 233 connected to the straight line 232. The straight line 232 coincides with the radial direction of the grinding ring 20. On one side of the discharge slot 22 the arc 233 is between the straight line 232 and the discharge slot 22, and on the other side of the discharge slot 22 the straight line 232 is between the arc 233 and the discharge slot 22. Therefore, when the striking hammer 33 rotates, the kitchen waste firstly enters the crushing groove 231 along the arc 233, and then is clamped and struck by the straight line 232 between the striking hammer 33 and the crushing groove 231 to crush the kitchen waste, and as the kitchen waste contains more water or oil, the water or oil is driven by the striking hammer 33 to adjust and rotate so as to impact the kitchen waste clamped in the crushing groove 231, so that the kitchen waste can be circularly crushed.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
