Description

Technical Field

[0001] This invention relates to the field of food waste disposal technology in the kitchen, and in particular to a waste disposer. Background Technology

[0002] When people wash pots and pans, garbage often flows directly into the sewer with the water. Over time, this can clog the sewers, causing significant inconvenience to households. The emergence of kitchen garbage disposers has solved this problem. A kitchen garbage disposer is a household kitchen appliance that uses a motor to drive a grinding disc, causing the garbage to impact, cut, and rub against the grinding parts on the disc, thereby reducing the volume of the garbage and allowing it to be directly disposed of through the sewer.

[0003] Most garbage disposers on the market are single-layer grinding discs, which do not grind the garbage sufficiently. The resulting garbage particles are relatively large and easily clog the drain. Alternatively, a serrated blade is assembled under the single-layer grinding disc, but this blade can only cut some fibrous materials and has little impact on the size of the garbage particles.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a garbage disposer that can perform layered grinding. By setting multiple grinding discs, the efficiency and quality of garbage disposal are improved, and the ground garbage particles are made finer, thus avoiding clogging of the sewer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A garbage disposal unit includes a grinding chamber, a grinding device disposed in the grinding chamber, and a drive shaft connected to the grinding device. The grinding device includes at least one grinding ring and at least two grinding discs. The grinding ring and the grinding discs are arranged to rotate relative to each other. The grinding discs are arranged sequentially along the axial direction of the drive shaft. At least two grinding discs cooperate with one grinding ring to grind garbage.

[0008] In the above solution, by setting a grinding ring and multiple grinding discs in the grinding chamber, the food waste is ground step by step, making the grinding more thorough and the ground waste particles finer, thus avoiding clogging the sewer.

[0009] Furthermore, as the waste is processed sequentially through the grinding discs, the channels for the flow of waste grinding particles in each grinding disc working area gradually narrow.

[0010] Preferably, the diameters of the various grinding discs increase sequentially.

[0011] In the above scheme, by strictly limiting the size of the channel through which the waste grinding particles flow from each work area to the next work area, the waste is fully ground in each work area, ultimately forming finer waste grinding particles, thus preventing blockage of the sewer.

[0012] Furthermore, each of the grinding discs is mounted on a drive shaft, and the drive shaft drives each grinding disc to rotate;

[0013] Preferably, the grinding ring is disposed on the outer periphery of each grinding disc;

[0014] Preferably, the grinding ring is installed on the inner wall of the grinding chamber, and the outer peripheral edge of each grinding disc forms a gap with the inner wall of the grinding ring.

[0015] Furthermore, the grinding device includes a first grinding disc, a second grinding disc, and a common grinding ring. The first grinding disc is located above the second grinding disc.

[0018] Preferably, the first grinding hole and the second grinding hole have equal axial lengths;

[0022] Preferably, the grinding element on the second grinding disc includes a grinding hammer arranged radially along the second grinding disc. The grinding hammer is movably connected to the second grinding disc via a connector and reciprocates radially along the second grinding disc.

[0023] Preferably, the grinding hammer on the second grinding disc includes a hammer head and a hammer handle. A through hole is provided on the hammer handle. One end of the connector is installed on the grinding disc, and the other end passes through the through hole to limit the grinding hammer to reciprocate radially along the second grinding disc.

[0024] In the above scheme, by setting a grinding hammer that reciprocates radially along the second grinding disc, the grinding hammer and the grinding ring grind the waste grinding particles, thereby improving the grinding efficiency.

[0025] Furthermore, the grinding hammer on the second grinding disc is configured such that the hammer handle faces the center of the second grinding disc and the hammer head faces the outer periphery of the second grinding disc, and the range of motion of the hammer head is limited to the second grinding disc;

[0028] Preferably, the second grinding disc has two grinding hammers arranged in a centrally symmetrical manner.

[0029] Furthermore, both the first and second grinding discs are provided with grinding elements for grinding waste. The first grinding disc includes at least two types of grinding elements, which are any two of the following: a grinding hammer, a convex bulge, and a cutting blade. Each type of grinding element consists of two pieces, which are arranged alternately and at intervals in the circumferential direction.

[0034] Preferably, the convex bulge includes a central convexity and three peripheral convexities arranged around the central convexity. The three peripheral convexities are respectively connected to the central convexity. The bottom surfaces of the central convexity and the three peripheral convexities are all connected to the upper surface of the first grinding disc. The highest point of each of the three peripheral convexities is lower than the highest point of the central convexity.

[0035] Furthermore, two sets of drainage holes are provided on the first grinding disc, each set of drainage holes corresponds to each grinding hammer, and each set of drainage holes and each convex bulge are respectively arranged on both sides of the grinding hammer along the circumferential direction.

[0037] The following beneficial effects are achieved by adopting the technical solution described in this invention:

[0038] The garbage disposer provided by this invention grinds food waste step by step by setting a grinding ring and multiple grinding discs in the grinding chamber. This avoids the ineffective grinding caused by garbage of different sizes piling up together, making the grinding more thorough and the resulting garbage particles finer, thus preventing blockage of the sewer.

[0039] The garbage disposer provided by this invention strictly limits the size of the channel through which the garbage grinding particles flow from each working zone to the next working zone, so that the garbage is fully ground in each working zone, ultimately forming finer garbage grinding particles and preventing the sewer from being blocked.

[0046] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0048] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] like Figure 1 As shown, a garbage disposal unit includes a grinding chamber 2, a grinding device disposed in the grinding chamber 2, and a drive shaft 51 connected to the grinding device. The grinding device includes at least one grinding ring and at least two grinding discs. The grinding ring and the grinding discs are arranged to rotate relative to each other. Each grinding disc is arranged sequentially along the axial direction of the drive shaft 51. At least two grinding discs cooperate with one grinding ring to grind garbage.

[0051] Specifically, the garbage disposer is fixed to the lower part of the water storage tank 1. The upper part of the garbage disposer includes a grinding chamber 2, and the lower part includes a motor 5. The drive shaft 51 of the motor 5 extends axially toward the grinding chamber 2 and is located at the center of the grinding chamber 2. The central axis of the drive shaft 51 coincides with the central axis of the grinding chamber 2. A grinding device connected to the drive shaft 51 is installed inside the grinding chamber 2. The grinding device includes multiple grinding rings and multiple grinding discs. The grinding rings and grinding discs are arranged to rotate relative to each other. The central axis of the grinding rings coincides with the central axis of the grinding chamber 2. Each grinding disc is arranged sequentially along the axial direction of the drive shaft 51. The multiple grinding discs cooperate with one grinding ring to grind the garbage in the working area.

[0052] This invention uses multiple grinding discs in conjunction with a grinding ring to gradually grind food waste, improving waste disposal efficiency and preventing waste of different sizes from accumulating together and failing to grind effectively. This results in more thorough grinding, finer grinding particles, and avoids clogging sewers.

[0053] Different grinding discs, in conjunction with the corresponding grinding rings, grind the waste in each grinding disc's working zone into different volumes, allowing for more thorough grinding. For example, waste must be ground to a specific size in each grinding disc's working zone before flowing into the next grinding disc's working zone for further grinding. To further enhance waste grinding, in this embodiment of the invention, along the sequence of waste passing through the grinding discs, the channels for the flow of waste grinding particles in each grinding disc's working zone gradually narrow, while the diameter of each grinding disc gradually increases.

[0054] The grinding ring and grinding disc rotate relative to each other, and their interaction grinds the waste. This relative rotation can be either the grinding disc rotating around the central axis of the grinding chamber 2, the grinding ring rotating around the central axis of the grinding chamber 2, or both rotating around the central axis of the grinding chamber 2. In a preferred embodiment, the grinding disc rotates around the central axis of the grinding chamber 2. To enable this rotation, the central axis of the grinding disc coincides with the central axis of the grinding chamber 2. Each grinding disc is mounted on a drive shaft 51, which drives the grinding discs to rotate. The grinding ring is positioned on the outer periphery of each grinding disc and mounted on the inner wall of the grinding chamber 2. A gap is formed between the outer edge of each grinding disc and the inner wall of the grinding ring, allowing the ground waste particles to flow into the working area of ​​the next grinding disc. Since the diameter of each grinding disc increases progressively from top to bottom, the gap between the outer edge of each grinding disc and the inner wall of the grinding ring also decreases progressively from top to bottom. This results in a progressively narrower channel for the waste particles to flow into the next grinding disc's working area, ensuring thorough grinding of the waste within each grinding disc's working area.

[0055] The following description uses a grinding device consisting of a grinding ring and two grinding discs as an example to illustrate the specific structure of the grinding device.

[0056] In an embodiment of the present invention, the grinding device of the garbage disposer includes a first grinding disc 41, a second grinding disc 42, and a common grinding ring 3. The first grinding disc 41 is located above the second grinding disc 42. The first grinding disc 41 and the common grinding ring 3 cooperate to perform preliminary processing of the garbage. The second grinding disc 42 and the common grinding ring 3 cooperate to further process the garbage after preliminary processing.

[0057] Specifically, such as Figure 3 and Figure 4As shown, both the first grinding disc 41 and the second grinding disc 42 have mounting holes at their centers. The drive shaft 51 passes through the mounting holes at the centers of the second grinding disc 42 and the first grinding disc 41 from bottom to top, so that the second grinding disc 42 and the first grinding disc 41 are mounted on the drive shaft 51. The common grinding ring 3 is fixed to the inner wall of the grinding chamber 2. The drive shaft 51 drives the first grinding disc 41 and the second grinding disc 42 to rotate. The first grinding disc 41 cooperates with the common grinding ring 3 to perform preliminary grinding of the garbage, forming relatively large garbage grinding particles. These garbage grinding particles flow to the working area where the second grinding disc 42 is located. The second grinding disc 42 cooperates with the common grinding ring 3 to further grind the garbage grinding particles, making the garbage grinding particles smaller.

[0058] like Figure 1 and Figure 2 As shown, the common grinding ring 3 has two sets of grinding holes, namely the first grinding hole 31 and the second grinding hole 32, which are evenly distributed on the peripheral wall of the common grinding ring 3. The first grinding hole 31 is located at the upper middle end of the common grinding ring 3, and the second grinding hole 32 is located at the lower end of the common grinding ring 3. The first grinding hole 31 is wider than the second grinding hole 32. The sum of the axial lengths of the first grinding hole 31 and the second grinding hole 32 is equal to or greater than half of the axial length of the common grinding ring 3. The first grinding hole 31 and the second grinding hole 32 have equal axial lengths. Compared with other parts of the common grinding ring 3, the grinding holes are equivalent to the cutting teeth on the common grinding ring 3, which can cut the garbage thrown onto it. The sum of the axial lengths of the first grinding hole 31 and the second grinding hole 32 is equal to or greater than half of the axial length of the common grinding ring 3, that is, the axial lengths of the first grinding hole 31 and the second grinding hole 32 are relatively long, which is equivalent to the length of the cutting teeth on the common grinding ring 3 being relatively long, which is more conducive to cutting garbage.

[0059] The plane containing the first grinding disc 41 intersects with the first grinding hole 31, meaning the lower end face of the first grinding hole 31 is at a lower height than the lower end face of the first grinding disc 41. The plane containing the first grinding disc 41 divides the first grinding hole 31 into upper and lower parts. Preferably, the axial length of the upper part is equal to or greater than twice the axial length of the lower part. Thus, the lower part of the first grinding hole 31 is located within the working area of ​​the second grinding disc 42. When the waste grinding particles flowing from the working area of ​​the first grinding disc 41 enter the working area of ​​the second grinding disc 42, they can be further ground by this part of the grinding hole when they are thrown onto it, without needing to flow onto the second grinding disc 42 or the second grinding hole 32 for further grinding, thus improving grinding efficiency. Furthermore, the waste in the working area of ​​the first grinding disc 41 is raw waste, which is the most difficult to grind compared to the waste in the working areas of other grinding discs. The axial length of the upper part of the first grinding hole 31 is longer than the axial length of the lower part, ensuring the grinding quality and efficiency within the working area of ​​the first grinding disc 41.

[0060] The lower end face of the second grinding hole 32 is on the same horizontal plane as the lower end face or the upper end face of the second grinding disk 42. Preferably, the lower end face of the second grinding hole 32 is on the same horizontal plane as the lower end face of the second grinding disk 42. In this way, the common grinding ring 3 opposite to the working area of ​​the second grinding disk 42 has grinding holes at both the upper and lower parts. The waste grinding particles flowing into the working area of ​​the second grinding disk 42 are already relatively small. Under the action of centrifugal force, they will be thrown onto the common grinding ring 3 opposite to the working area of ​​the second grinding disk 42. The common grinding ring 3 has grinding holes at both the upper and lower parts, which makes the further grinding of waste grinding particles faster and improves grinding efficiency.

[0061] As an alternative, the grinding ring does not have grinding holes, but the inner wall of the grinding ring is uniformly decorated with raised or spiral patterns, which can further grind the waste.

[0062] Waste flows from the water storage tank 1 into the working area of ​​the first grinding disc 41 and is initially ground, forming relatively large waste grinding particles that can flow out of the working area of ​​the first grinding disc 41. These waste grinding particles flow into the working area of ​​the second grinding disc 42 and are further ground, forming finer waste grinding particles that can flow out of the working area of ​​the second grinding disc 42. The finer waste grinding particles flow out of the working area of ​​the second grinding disc 42 and are discharged into the sewer. The working areas of both the first grinding disc 41 and the second grinding disc 42 have channels for the waste grinding particles to flow to the next working area. The first grinding disc 41 is provided with several first through holes for the waste grinding particles to pass through, and the second grinding disc 42 is provided with several second through holes for the waste grinding particles to pass through. The diameter of the second through holes is smaller than the diameter of the first through holes. The first through holes on the first grinding disc 41 for the passage of the waste grinding particles are drainage holes provided on the first grinding disc 41, and the second through holes on the second grinding disc 42 for the passage of the waste grinding particles are drainage holes provided on the second grinding disc 42. The drainage holes on the first grinding disc 41 are wider than the drainage holes on the second grinding disc 42.

[0063] The working area of ​​the first grinding disc 41, through which the waste grinding particles flow to the working area of ​​the second grinding disc 42, also includes the first grinding hole 31, the gap formed by the inner wall of the common grinding ring 3 and the outer peripheral edge of the first grinding disc 41, and the working area of ​​the second grinding disc 42, through which the waste grinding particles flow to the next grinding disc working area or the sewer, also includes the second grinding hole 32, the gap formed by the inner wall of the common grinding ring 3 and the outer peripheral edge of the second grinding disc 42. The first grinding hole 31 is wider than the second grinding hole 32, and the gap formed by the inner wall of the common grinding ring 3 and the outer peripheral edge of the first grinding disc 41 is wider than the gap formed by the inner wall of the grinding ring and the outer peripheral edge of the second grinding disc 42. In an embodiment of the present invention, the width of the channel in the working area of ​​the first grinding disc 41 for the flow of waste grinding particles to the working area of ​​the second grinding disc 42 is 4-5 mm, and the width of the channel in the working area of ​​the second grinding disc 42 for the flow of waste grinding particles to the next working area of ​​the grinding disc or the sewer is 2-3 mm. Preferably, the channel in the working area of ​​the first grinding disc 41 for the flow of waste grinding particles to the working area of ​​the second grinding disc 42 is 5 mm, and the channel in the working area of ​​the second grinding disc 42 for the flow of waste grinding particles to the next working area or the sewer is 2 mm. That is, the gaps formed by the drain hole, the first grinding hole 31, the inner wall of the common grinding ring 3, and the outer periphery of the first grinding disc 41 are all 5 mm, and the gaps formed by the drain hole, the second grinding hole 32, the inner wall of the common grinding ring 3, and the outer periphery of the second grinding disc 42 are all 2 mm. By strictly limiting the size of the channel in each working area for the flow of waste grinding particles to the next working area, the waste is fully ground in each working area, ultimately forming finer waste grinding particles, preventing clogging of the sewer.

[0064] Both the first grinding disc 41 and the second grinding disc 42 are provided with grinding components for grinding waste. The grinding components on the second grinding disc 42 include grinding hammers arranged radially along the second grinding disc 42. The grinding hammers are movably connected to the second grinding disc 42 through a connector 4214 and reciprocate radially along the second grinding disc 42.

[0065] Specifically, both the first grinding disc 41 and the second grinding disc 42 are equipped with grinding hammers. The second grinding disc 42 has two grinding hammers, which are arranged symmetrically at the center (see [reference]). Figure 3 The grinding hammers on the second grinding disc 42 are the third grinding hammer 421 and the fourth grinding hammer 422, respectively. The specific settings of the grinding hammers on the second grinding disc 42 will be explained below, taking the third grinding hammer 421 as an example.

[0066] The third grinding hammer 421 includes a handle 4212 and a head 4211. A through hole 4213 is provided on the handle 4212. One end of a connector 4214 is mounted on the grinding disc, and the other end passes through the through hole 4213, limiting the grinding hammer's radial reciprocating motion along the second grinding disc 42. The radial length of the cross-section of the connector 4214 passing through the through hole 4213 is smaller than the radial length of the cross-section of the through hole 4213, allowing the third grinding hammer 421 to move radially along the second grinding disc 42. A preferred embodiment of the connector 4214 is a rivet.

[0067] The projection of through hole 4213 onto the horizontal plane where the second grinding disk 42 is located is a composite graphic (see reference). Figure 3 The rivet includes a rectangle and two arc segments. The two arc segments are connected to the two widths of the rectangle and extend away from the rectangle. The length of the rectangle extends radially along the second grinding disk 42. The length of the rivet head along the radial direction of the second grinding disk 42 is greater than the length of the through hole 4213 along the radial direction of the second grinding disk 42.

[0068] The second grinding disc 42 can also be provided with corresponding through holes. The connector 4214 passes through the hammer handle 4212 and the through holes of the second grinding disc 42 to connect the third grinding hammer 421 to the second grinding disc 42.

[0069] As an alternative, the connector 4214 can be a bolt, and the projection of the through hole 4213 onto the horizontal plane where the second grinding disc 42 is located is elliptical.

[0070] The grinding hammer on the second grinding disc 42 is positioned such that the hammer handle 4212 faces the center of the second grinding disc 42, and the hammer head 4211 faces the outer periphery of the second grinding disc 42. The movement range of the hammer head 4211 is limited to the second grinding disc 42, meaning that the hammer head 4211 does not cross the outer periphery of the grinding disc. When the third grinding hammer 421 reciprocates radially along the second grinding disc 42, the entire hammer head 4211 remains on the second grinding disc 42, and its end does not move above the gap formed between the outer edge of the second grinding disc 42 and the grinding ring. The projection of the end face of the hammer head 4211 of the third grinding hammer 421, near the common grinding ring, onto the horizontal plane where the second grinding disc 42 is located, is an arc-shaped curve segment, and the arc-shaped curve segment has the same center as the common grinding ring 3. In this way, the end face of the hammer head 4211 of the third grinding hammer 421 cooperates with the grinding ring to further and thoroughly grind the waste grinding particles that fall into it, ensuring that the ground waste grinding particles are finer, thus improving grinding efficiency and grinding quality. In order to increase the area between the end face of the hammer head 4211 of the third grinding hammer 421 and the inner wall of the grinding ring, the hammer head 4211 of the third grinding hammer 421 is larger than the hammer head 4211 set on the first grinding disc 41, so that the end face of the hammer head 4211 of the third grinding hammer 421 and the grinding ring can better cooperate for grinding.

[0071] The fourth grinding hammer 422 has the same structure as the third grinding hammer 421.

[0072] like Figure 3 As shown, multiple rows of drainage holes are evenly arranged on the second grinding disc 42, with each row of drainage holes arranged radially around the central through hole.

[0073] The first grinding disc 41 includes at least two types of grinding components, which are any two of grinding hammers, convex humps, and cutting blades. Each type of grinding component consists of two pieces, which are arranged alternately in the circumferential direction. Preferably, the grinding components on the first grinding disc 41 include two grinding hammers, two convex humps, and two cutting blades. The convex humps are located between the grinding hammers and the cutting blades. The two grinding hammers are arranged in a centrally symmetrical manner, and / or the two convex humps are arranged in a centrally symmetrical manner, and / or the two cutting blades are arranged in a centrally symmetrical manner.

[0074] Specifically, a first grinding hammer 411, a second grinding hammer 412, a first convex 413, a second convex 414, a first cutting blade 415, and a second cutting blade 416 are disposed on the first grinding disc 41. The first grinding hammer 411 and the second grinding hammer 412 are rotatably disposed on the first grinding disc 41, while the first convex 413 and the second convex 414, the first cutting blade 415, and the second cutting blade 416 are fixed to the first grinding disc 41. The first grinding hammer 411 and the second grinding hammer 412 are symmetrically arranged around the center of the first grinding disc 41, the first convex 413 and the second convex 414 are symmetrically arranged around the center of the first grinding disc 41, and the first cutting blade 415 and the second cutting blade 416 are symmetrically arranged around the center of the first grinding disc 41.

[0075] The line connecting the two grinding hammers and the line connecting the two cutting blades are perpendicular to each other. That is, the first grinding hammer 411, the second grinding hammer 412, the first cutting blade 415 and the second cutting blade 416 are located at four positions that can divide the first grinding disc 41 into four equal parts. In this way, the probability of the garbage in the working area of ​​the first grinding disc 41 being hammered or cut can be increased, thereby improving the grinding efficiency.

[0076] The first grinding hammer 411 is adjacent to the first protrusion 413, and the first grinding hammer 411 is relatively close to the first protrusion 413, while it is relatively far from the second protrusion 414. The total area occupied by the adjacent first grinding hammer 411 and the first protrusion 413 on the upper surface of the first grinding disc 41 is less than one-quarter of the area of ​​the upper surface of the first grinding disc 41. The same applies to the second grinding hammer 412 and the second protrusion 414. The first grinding hammer 411 and the first protrusion 413 are relatively close, and they work together to repeatedly hammer the waste. At the same time, since the first grinding hammer 411 and the second grinding hammer 412 can rotate freely, they will avoid hard objects when they encounter them. At this time, the first protrusion 413 and the second protrusion 414, which are close to the first grinding hammer 411 and the second grinding hammer 412 respectively, can hammer the hard objects, thereby improving the grinding efficiency of the first grinding device for food waste.

[0077] The first convex bulge 413 consists of a central bulge and three peripheral bulges surrounding the central bulge. The three peripheral bulges are connected to the central bulge, and the bottom surfaces of both the central bulge and the three peripheral bulges are connected to the upper surface of the first grinding disc 41. The highest point of each of the three peripheral bulges is lower than the highest point of the central bulge, and the highest points of the three peripheral bulges are located at their points of contact with the central bulge. The surfaces of both the central bulge and the three peripheral bulges are curved surfaces; visually, they appear to be part of a sphere. Compared to a single convex bulge, this design of the first convex bulge 413 increases the impact area with food waste, enabling more effective impact. The second convex bulge 414 has the same design as the first convex bulge 413.

[0078] Two sets of drainage holes are provided on the first grinding disc 41. Each set of drainage holes corresponds to each grinding hammer. Each set of drainage holes and each convex bulge are respectively set on both sides of the grinding hammer along the circumferential direction.

[0079] Specifically, the first grinding disc 41 is provided with a first set of drainage holes 417 and a second set of drainage holes 418. The first set of drainage holes 417 is located near the side of the first grinding hammer 411 away from the first protrusion 413, and the second set of drainage holes 418 is located near the side of the second grinding hammer 412 away from the second protrusion 414. Each set of drainage holes contains 6-8 holes. This arrangement allows qualified waste grinding particles, after being crushed by the grinding hammer and the protrusion, to quickly flow from the drainage holes onto the second grinding device.

[0080] Waste enters the working area of ​​the first grinding disc 41 through the water storage tank 1. After being processed by the grinding hammer, protrusion, cutting blade, the first grinding disc 41, and the common grinding ring 3 including the upper part of the first grinding hole 31, the waste is turned into 4-5mm waste grinding particles. These particles enter the working area of ​​the second grinding disc 42 through the water leakage hole on the first grinding disc 41, the first grinding hole 31, and the gap between the first grinding disc 41 and the common grinding ring 3. After being processed by the grinding hammer, the second grinding disc 42, and the common grinding ring 3 including the lower part of the first grinding hole 31 and the second grinding hole 32, the waste grinding particles are ground into even smaller 2-3mm particles. Finally, these particles flow out through the water leakage hole on the second grinding disc, the second grinding hole 32, and the gap between the second grinding disc 42 and the common grinding ring 3 and are discharged into the sewer. If the garbage grinding particles are larger than 5mm, they will continue to be ground in the working area of ​​the first grinding disc 41 until they are ground into garbage grinding particles smaller than or equal to 5mm before they can enter the working area of ​​the second grinding disc 42. Similarly, the garbage grinding particles flowing into the working area of ​​the second grinding disc 42 must be ground into garbage grinding particles smaller than or equal to 2mm before they can flow out of the working area of ​​the second grinding disc 42 and be discharged into the sewer.

[0081] In an embodiment of the present invention, a third grinding disc may be provided below the second grinding disc 42. The third grinding disc is fixed on the drive shaft 51. The third grinding disc cooperates with the common grinding ring 3 to further process the waste grinding particles. Preferably, the third grinding disc is provided with grinding hammers and drainage holes. The grinding hammers on the third grinding disc are provided in the same way as the grinding hammers on the second grinding disc 42.

[0082] Alternatively, in an embodiment of the present invention, a second grinding ring and a third grinding disc located below the second grinding disc 42 may be included. The third grinding disc is fixed on the drive shaft 51, and the second grinding ring is disposed on the outer periphery of the third grinding disc and installed on the inner wall of the grinding chamber 2. The second grinding ring and the third grinding disc cooperate to further process the waste grinding particles.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
