Description

Technical Field

[0001] This invention relates to the technical field of garbage disposer blade assembly components, and more specifically, to a garbage disposer blade assembly. Background Technology

[0002] Kitchen garbage disposers are typically installed under the kitchen sink. A motor drives a blade to break down food waste into small particles, which mix with water and are then flushed down the drain to decompose naturally. This eliminates the various hassles associated with food waste, significantly improving the quality of life for residents.

[0003] In practical applications, the blade assembly of a garbage disposal unit is its core structure, determining the effectiveness of garbage disposal. Kitchen waste usually contains a mixture of difficult-to-process items, mainly categorized into two types: first, hard waste, such as bones and fruit pits; and second, highly resilient waste, such as meat skin and roots. Existing garbage disposal units are inefficient at processing these types of waste, finding it difficult or even impossible to handle them. Summary of the Invention

[0004] The purpose of this invention is to provide a garbage disposal blade assembly that incorporates components such as agitators and tearing teeth. Through a uniquely designed hammering and cutting structure involving the interaction of a fixed blade cylinder and a rotatable blade disc, this assembly can crush hard garbage and cut highly resilient garbage.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A garbage disposal blade assembly includes a cylindrical fixed blade cylinder and a circular rotating blade disc. The outer side of the blade cylinder is provided with several rows of protruding vertical strips, which are embedded in slots inside the garbage disposal liner, so that the blade cylinder is fixedly suspended above the blade disc. The inner side of the blade cylinder is provided with several rows of protruding teeth, wherein each row of protruding teeth includes a first protruding tooth, a second protruding tooth, and a third protruding tooth and a fourth protruding tooth forming a concave-convex blade, arranged from top to bottom. The lower part of the blade cylinder is provided with several spaced oblique teeth.

[0006] As a further optimization of this solution, a motor shaft is connected at the center of the cutter head, two rotating hammers are symmetrically arranged at the center of the circle above the cutter head, and several agitators are symmetrically arranged at the center of the circle above the cutter head outside the rotation range of the rotating hammers. The rotating holes of the rotating hammers are rotated and fitted onto rivets, and the bottom of the rivets is fixed to the cutter head. Several vertical cutting blades are evenly arranged around the upper perimeter of the cutter head, and several horizontal cutting blades are evenly arranged around the lower perimeter of the cutter head.

[0007] As a further optimization of this solution, the distance between the circumferential edge of the cutter disc and the inner side of the cutter cylinder is 0.01-2 mm, the distance between the vertical blade of the vertical cutter and the oblique teeth of the cutter cylinder is 0.01-2 mm, the distance between the upper blade of the vertical cutter and the lower blade of the fourth protruding tooth is 0.01-2 mm, and the distance between the upper blade of the transverse cutter and the lower blade of the oblique teeth of the cutter cylinder is 0.01-2 mm.

[0008] As a further optimization of this solution, the rotating hammer includes an upper hammer head, a vertical connecting strip, and a lower hammer head, wherein the furthest point of rotation of the upper and lower hammer heads is flush with the circumference of the cutter head.

[0009] As a further optimization of this solution, the upper hammer head of the rotating hammer strikes the grooved edge formed by the lower edge of the third protruding tooth and the upper edge of the fourth protruding tooth on the inner side of the blade cylinder. The distance between the upper edge of the upper hammer head and the lower edge of the third protruding tooth is 0.01-2 mm, the distance between the lower edge of the upper hammer head and the upper edge of the fourth protruding tooth is 0.01-2 mm, the distance between the vertical edge of the vertical connecting strip and the protruding edge of the fourth protruding tooth is 0.01-2 mm, and the distance between the lower hammer head and the oblique teeth of the blade cylinder is 0.01-2 mm.

[0010] As a further optimization of this solution, four externally rotating turbine blades are symmetrically and evenly distributed at the center of the lower circle of the cutter head, which generate external rotation force when the cutter head rotates forward.

[0011] Compared with existing technologies, the beneficial effects of the present invention are as follows: In this invention, the waste is initially treated by the agitator blade and the tearing teeth of the blade cylinder. When the agitator blade rotates, the waste is agitated and pushed to the edge by centrifugal force. When the waste reaches the inside of the blade cylinder, the tearing teeth will initially tear the rotating waste.

[0012] This invention utilizes a unique and original hammering structure: the rotating hammer interacts with the grooves formed by the third and fourth protruding teeth on the inner side of the fixed blade cylinder. During operation, the blade disc is driven to rotate at high speed by the motor shaft, and the two rotating hammers also rotate at high speed along with the blade disc. As the blade disc rotates, the debris is pushed towards the inside of the blade cylinder under centrifugal force, becoming lodged in the rows of protruding teeth on the inner side of the blade cylinder. The upper hammer head of the rotating hammer rotates at high speed through the grooves formed by the third and fourth protruding teeth, quickly breaking up the hard debris stuck in the grooves. The lower hammer head of the rotating hammer also rotates at high speed, breaking up hard debris protruding outwards from the oblique tooth gaps of the blade cylinder. The vertical connecting strip edge between the upper and lower hammer heads and the vertical edge edge of the fourth protruding tooth also simultaneously act to break up the debris.

[0013] This invention employs a unique cutting structure, namely, the interaction of a vertical cutting blade, a horizontal cutting blade, and helical teeth on the cutter barrel. When the cutter head rotates at high speed, the vertical cutting blade and the helical teeth generate a shearing force, which is far greater than ordinary shearing force, enabling rapid and effective cutting of highly tough waste. The horizontal cutting blade, along with the lower edge of the helical teeth, performs a secondary cut as the waste passes through the gaps between the helical teeth and is discharged downwards.

[0014] In this invention, the gap between the oblique teeth is the necessary channel for the waste to be discharged downwards, and we control the particle size of the waste by controlling the size of the gap. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of the invention easier to understand, the invention will be further explained below with reference to specific illustrations.

[0017] To address the problem that existing blades are not effective at processing hard waste, such as bones and fruit pits, as well as highly resilient waste, such as skin and roots; like Figures 1 to 3 As shown, the garbage disposal blade assembly of this application includes a cylindrical fixed blade cylinder 1 and a circular rotating blade disc. The outer side of the blade cylinder 1 is provided with several rows of protruding vertical strips 8. The protruding vertical strips 8 are embedded in the slots inside the garbage disposal inner liner so that the blade cylinder 1 is fixedly suspended above the blade disc. The inner side of the blade cylinder 1 is provided with several rows of protruding teeth. Each row of protruding teeth includes a first protruding tooth 12 and a second protruding tooth arranged from top to bottom for tearing, and a third protruding tooth 13 and a fourth protruding tooth 14 forming a concave-convex blade. The lower part of the blade cylinder 1 is provided with several spaced oblique teeth 9. The motor shaft 5 is connected at the center of the cutter head. Two rotating hammers 4 are symmetrically arranged at the center of the two circles above the cutter head. Several stirring blades 6 are symmetrically arranged at the center of the two circles above the cutter head outside the rotation range of the rotating hammers 4. The rotating holes of the rotating hammers 4 are rotated and fitted onto the rivets 3. The bottom of the rivets 3 is fixed to the cutter head. Several vertical cutting blades 7 are evenly arranged around the four edges of the upper part 2 of the blade disc, and several horizontal cutting blades 11 are evenly arranged around the outer edges of the lower part 10 of the blade disc; The distance between the circumferential edge of the cutter head and the inner side of the cutter tube 1 is 0.01-2 mm. The distance between the vertical blade of the vertical cutter 7 and the oblique tooth 9 of the cutter tube 1 is 0.01-2 mm. The distance between the upper blade of the vertical cutter 7 and the lower blade of the fourth protruding tooth 14 is 0.01-2 mm. The distance between the upper blade of the transverse cutter 11 and the lower blade of the oblique tooth 9 of the cutter tube 1 is 0.01-2 mm.

[0018] like Figures 4 to 6 As shown, the rotating hammer 4 includes an upper hammer head 41, a vertical connecting bar 43, and a lower hammer head 42. The furthest point of rotation of the upper and lower hammer heads is flush with the circumference of the cutter head. The upper hammer head 41 of the rotating hammer 4 rotates and strikes the grooved edge formed by the lower edge of the third protruding tooth 13 and the upper edge of the fourth protruding tooth 14 on the inner side of the cutter cylinder 1. The distance between the upper edge of the upper hammer head 41 and the lower edge of the third protruding tooth 13 is 0.01-2 mm, the distance between the lower edge of the upper hammer head 41 and the upper edge of the fourth protruding tooth 14 is 0.01-2 mm, the distance between the vertical edge of the vertical connecting bar 43 and the protruding edge of the fourth protruding tooth 14 is 0.01-2 mm, and the distance between the lower hammer head 42 and the oblique tooth 9 of the cutter cylinder 1 is 0.01-2 mm.

[0019] like Figure 7 As shown, four externally rotating turbine blades 15 are symmetrically and evenly distributed at the center of the circle 10 below the cutter head, generating external rotation force when the cutter head rotates forward.

[0020] Specifically, when the cutter head rotates at high speed, the water inlet system starts to inlet water, and the agitator 6 will quickly agitate and cut the garbage. The first protruding teeth 12 and the second protruding teeth around the perimeter will initially tear the garbage. Under the action of centrifugal force, the garbage is pushed upward to the edge of the rotating cutter head and the inside of the cutter cylinder 1, and stuck in the rows of protruding teeth on the inside of the cutter cylinder 1. The upper hammer head 41 of the rotating hammer 4 rotates at high speed and passes through the groove formed by the lower edge of the third protruding tooth 13 and the upper edge of the fourth protruding tooth 14, which can quickly break up hard garbage. The lower hammer head 42 of the rotating hammer 4 can also rotate at high speed and break up the hard garbage that is stuck in the gap of the oblique teeth 9 of the cutter cylinder 1. The vertical edge of the vertical connecting strip 43 between the upper and lower hammer heads and the vertical edge of the fourth protruding tooth 14 interact to break up the garbage.

[0021] At the same time, when the cutter head rotates at high speed, the vertical cutter 7 and the oblique tooth 9 form a strong shearing force, which can quickly and effectively cut high-toughness waste. When the waste passes through the gap of the oblique tooth 9 and is discharged downward, the horizontal cutter 11 and the lower edge of the oblique tooth 9 cut the waste a second time. Subsequently, the treated waste particles and water mix and enter the cutter head below 10, and are quickly discharged by the outer rotating turbine blades 15 of the cutter head below 10.

[0022] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
