Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Referring to fig. 1 to 5, the cutter head assembly of the garbage disposer comprises a cutter head 20, and a movable cutter body 25 and a boss which are arranged on the cutter head 20, wherein the cutter head 20 is located below a grinding ring 10 of the garbage disposer and can rotate relative to the grinding ring 10 under the driving of a corresponding motor (not shown), specifically, the grinding ring 10 is covered above to form a grinding cavity for grinding garbage materials, and a grinding hole is arranged on an annular wall of the grinding ring 10. Still be equipped with clamping ring 30 on the last border of grinding ring 10, wherein, clamping ring 30 shelves on the last port of grinding ring 10, and the interior border of this clamping ring 30 has a plurality of inwards extended and turns over the upright tooth 31 of rolling over the formation upwards along the circumferencial direction interval arrangement, and this setting up of tooth can disperse and the breakage when the rubbish material of big volume gets into the grinding chamber.

In order to fully crush the garbage materials in the grinding ring 10, a first boss 23 and a second boss 24 are further arranged on the upper surface of the cutter disc 20, the first boss 23 is obliquely turned upwards and extends from the upper surface of the cutter disc 20, and the second boss 24 is vertically turned upwards and extends from the upper surface of the cutter disc 20. Specifically, there are a plurality of first bosses 23 and a plurality of second bosses 24, and they are all arranged at intervals along the circumferential direction of the cutter disc 20, and more specifically, the first bosses 23 are located inside the second bosses 24, that is, the distance from the position of the first bosses 23 to the axial line of the cutter disc 20 is smaller than the distance from the position of the second bosses 24 to the axial line of the cutter disc 20, as shown in detail in fig. 5.

With continued reference to fig. 5, the cutter head 20 is provided with a movable cutter body 25, and the movable cutter body 25 is hinged to the cutter head 20 to be capable of rotating 360 degrees relative to the cutter head 20. The cutter head that is equipped with on the cutter head still is equipped with step portion 250, and the setting of step portion 250 can provide a plurality of cutting edge portions to the movable cutter body 25 is rotating the in-process, and step portion 250 on the cutter head can form the cutting cooperation with first boss 23 and/or second boss 24, improves the crushing effect of rubbish material.

Referring to fig. 3 and 4, the bottom of the cutter disc 20 is further provided with a cutting disc 40 which can rotate along with the cutter disc 20, the outer periphery of the cutting disc 40 is circumferentially provided with a plurality of cutting teeth extending outwards, and at least part of each cutting tooth 41 is exposed out of the outer edge of the cutter disc 20 so as to cut the material entering the drainage chamber along with the water flow. Specifically, in the present embodiment, the cutting teeth on the cutting disk 40 include a first cutting tooth 41 extending obliquely upward and a second cutting tooth 42 extending obliquely downward, wherein the first cutting tooth 41 and the second cutting tooth 42 are sequentially arranged at intervals along the circumferential direction of the cutting disk 40, that is, one of any two adjacent cutting teeth is the first cutting tooth 41, and the other one is the second cutting tooth 42. Because the first cutting teeth 41 and the second cutting teeth 42 are respectively inclined upwards and downwards, long fiber materials falling into the drainage chamber can be cut off for multiple times, and the problem of blockage of a sewer pipe is effectively avoided.

Referring to fig. 2, the outer edge of the cutter head 20 in this embodiment is folded upwards to form an annular flange 21, the annular flange 21 can form a cutting fit with the lower edge of the grinding ring 10, specifically, the lower edge of the grinding ring 10 can be inserted into the annular flange 21, and a channel 100 for garbage to flow through is formed between the annular flange 21 and the annular flange 21, specifically, the annular flange 21 of the cutter head 20 is located outside the lower edge of the grinding ring 10, during operation, the garbage crushed in the grinding ring 10 flows out from the lower edge of the grinding ring 10, then flows through the channel between the grinding ring 10 and the annular flange 21, and then flows into a drainage chamber through the annular flange 21 (the flow path of the garbage material is detailed in fig. 4).

In order to further improve the cutting efficiency between the annular flanging 21 of the cutter head 20 and the grinding ring 10 and further ensure that the garbage materials are effectively cut off in the process of flowing out of the grinding ring 10 from the inside of the grinding ring 10, a plurality of third cutting teeth 22 are arranged on the annular flanging 21 at intervals along the circumferential direction, correspondingly, the inner wall of each slot hole 11 is also provided with a fourth cutting tooth 12, therefore, in the rotating process of the cutter head 20, the long fiber materials passing through the slot hole 11 can be cut not only through the slot hole 11 and the edge of the annular flanging 21, but also through the fourth cutting teeth 12 in the slot hole 11 and the third cutting teeth 22 of the annular flanging 21, and the crushing effect of the garbage disposer is effectively improved.

The cutting disc arranged at the bottom of the cutter disc can rotate along with the cutter disc, when corresponding materials flow out of the grinding ring along with water flow and enter the drainage chamber, the materials can be cut again by the cutting disc arranged at the bottom of the cutter disc, the crushing effect of garbage materials is effectively improved, particularly, the arrangement of the first cutting teeth extending upwards in an inclined mode and the second cutting teeth extending downwards in an inclined mode on the cutting disc lengthens the cutting range of the peripheral edge of the cutting disc in the up-down direction, namely, an effective cutting interval can be formed between the highest point of the first cutting teeth and the lowest point of the second cutting teeth on the peripheral edge of the cutting disc, and long fiber materials can be effectively cut off by the first cutting teeth or/and the second cutting teeth when flowing out of the grinding cavity and falling into the cutting interval, so that the problem of blockage of a sewer pipe is solved.
