Detailed Description

The following describes the present invention with reference to the following embodiments.

As shown in the figures 1-2 of the drawings,

a helical tooth grinding ring for a food waste disposer comprises a helical tooth grinding ring 11 and a metal grinding ring 12 which is integrated with the helical tooth grinding ring in the axial direction, wherein the inner wall of the metal grinding ring is provided with a plurality of convex teeth 14,

the helical tooth grinding ring comprises a ring body, wherein a plurality of strip-shaped holes 13 are formed in the circumferential direction of the ring body to form the helical tooth grinding ring, and the length direction of the strip-shaped holes and the axial included angle a of the ring body meet the following relations: a is more than 0 and less than 90 degrees.

The intervals of the adjacent strip-shaped holes in the circumferential direction are the same.

Bar hole compares with the circular port, under the same specification, like under length, the bar hole is little because of its width, and the bar hole quantity that distributes in the circumference is far more than the circular port, improves crushing effect, and under the same width, the length in bar hole is far greater than the circular port, and the food waste that is located the bar hole is big with the area of smashing the tool bit contact, helps improving crushing effect, improves crushing efficiency.

In the technical scheme, the grinding ring of the oblique teeth is provided with the whole circle of oblique teeth, the oblique teeth are not provided with the cutting edges, the better grinding effect can be maintained all the time, the abrasion is not needed, the service life of the blade is prolonged, the width of the oblique teeth is about 3 mm, the length of the oblique teeth is about 20 mm, the inclination is about 15 degrees of the central angle of the grinding ring, when the grinding ring is used for grinding, the garbage is scattered all around when the grinding disc rotates and enters the oblique tooth grooves of the grinding ring, the oblique tooth grooves and the grinding cutter heads on the grinding disc are in a scissor shape to shear the garbage, the grinding speed of the garbage is accelerated, and a downward progressive function is given to the garbage, so that the garbage discharging speed is accelerated, the food garbage can be discharged into a sewer under the action of centrifugal force, and the contact time of the food garbage and the blade is longer, so that the centrifugal force of the food garbage and the blade can be correspondingly increased under the action of inertia, thereby greatly improving the efficiency of crushing the garbage; the main work of the convex teeth is as the movement track of the rotation of the crushing disc which is used for interfering the garbage crushing, thereby reducing the rotation speed of the garbage in the crushing cavity and reducing the crushing noise.

Wherein, the axial height of the grinding ring is equal to or slightly less than the height of the inner wall of the crushing cavity body for assembling the grinding ring.

Through adopting foretell high design for after grinding ring and crushing chamber main part assembly, the upper portion that smashes chamber main part inner wall can be protected to the metal grinding ring part, thereby the life of guarantee crushing chamber main part improves the intensity in whole crushing chamber.

For the assembly of the grinding ring and the crushing cavity body, the following is specified:

the traditional main structure of the crushing cavity is an upper and a lower split shell structures, so that the problems of high processing technology requirement and poor waterproof and sound insulation effects at the sealing position after assembly exist, the specific reason is shown in patent CN105170231B, in the patent document, the patent document is combined with the attached figure 3 of the specification, the number of the main structure is modified at the position, wherein 1 refers to an upper shell, 2 refers to a lower shell, 3 refers to a feeding port component mounting base which is equivalent to a feeding port component mounting base in the application, 4 refers to a feeding port which is equivalent to a feeding port component in the application, the figure can judge that the feeding port component mounting base and the upper end of the upper shell are of an integral structure, the upper shell and the lower shell are of a split structure, the upper shell and the lower shell are fixed by a plurality of screws in the circumferential direction, the matching position of the upper shell and the lower shell is sealed by a sealing ring (obtained by disassembling products sold in the market), and the fixing mode has a distance between, the sealing ring is small in stress between two adjacent screws at the screw fixing position, inconsistent in sealing and poor in sealing effect, so that when the sealing ring is used, water flows out from the sealing position easily, the sound insulation effect is poor, the matching requirements of the upper shell and the lower shell are high, the needed manufacturing process is complex, and the cost is high.

For matching the utility model discloses a grinding ring, on the above-mentioned basis of smashing chamber major structure, has the following design of smashing the chamber major structure.

As shown in fig. 4-6, the crushing chamber main body 5 comprises an upper shell and a lower shell, the upper shell and the lower shell are integrally formed to form the crushing chamber main body, and the upper end of the upper shell is an opening structure for installing the feeding port assembly installation seat 6. The feeding port component mounting seat is provided with a feeding port component 7.

Smash chamber major structure and adopt upper and lower casing integrated into one piece's design, separate dog-house subassembly mount pad and last casing and install again for garrulous chamber major part has the antidetonation, gives sound insulation, and is waterproof, has improved the life who smashes chamber major part and peripheral accessory greatly, has overcome waterproof problem.

A cylinder 8 is integrally formed on the inner wall of the main body of the crushing cavity, an internal thread hole is arranged on the axial direction of the cylinder and extends downwards from the upper end surface of the cylinder,

the screw 10 passes through the through hole on the feeding port component mounting seat to be connected with an internal thread hole so as to fixedly connect the feeding port component mounting seat with the crushing cavity main body.

The cylinder built-in mounting structure ensures the consistency of the crushing cavity main body in appearance.

The upper shell and the lower shell are made of metal materials, the metal materials are integrally formed through die casting, the shock resistance and the sound insulation effects of the crushing cavity main body are further enhanced, and the hard plastic injection molding and integral forming can be adopted.

On the basis of the scheme, in order to ensure the strength of the crushing cavity main body, the inner wall of the crushing cavity main body is also provided with a plurality of reinforcing ribs 9.

It will be apparent to those skilled in the art that modifications and variations can be made in the above-described embodiments, or some features of the invention may be substituted by equivalents, without departing from the spirit or scope of the invention.
