Description

Technical Field

[0001] This invention relates to the field of kitchen waste treatment technology, specifically to a household shredder with anti-clogging feed. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the amount of kitchen waste generated by households has been increasing year by year. Kitchen waste mainly includes leftover food, fruit and vegetable peels, cores, bones, eggshells and other organic waste. It is characterized by high water content, high organic matter content, easy rotting and odor. If it is not treated in time, it will not only breed mosquitoes and produce odors, but also have an adverse impact on the hygiene of the family kitchen environment. It will also put great pressure on the collection and transportation of urban domestic waste. Therefore, more and more families are choosing to install household kitchen waste disposers under the kitchen sink. Through mechanical grinding, kitchen waste is crushed into fine particles and discharged into the sewer pipe with the water flow, realizing the reduction of waste at the source and convenient treatment.

[0003] Existing household food waste disposers typically include components such as a feeding port, a grinding chamber, a drive motor, and a grinding disc. The feeding port is connected to the sink drain. After the user puts the food waste into the feeding port, the waste falls into the grinding chamber under gravity. The motor drives the grinding disc to rotate at high speed. Through centrifugal force, the waste moves relative to the grinding ring on the side of the grinding chamber, thereby achieving shearing, grinding, and pulverizing of the waste. The fine particles formed by grinding are flushed by water and enter the drain pipe through the discharge port at the bottom of the grinding chamber, and are eventually discharged.

[0004] In existing technologies, the feeding port is usually a simple straight cylinder structure. When users put in a large amount or long strips of kitchen waste at once, the waste tends to accumulate and compact in the center of the feeding port, forming a blockage. This prevents the material from falling smoothly into the grinding chamber, requiring manual stirring and assistance, which affects the user experience. The grinding disc and motor shaft are mostly rigidly connected. When processing high-fiber waste, the fibers tend to get tangled on the disc or shaft and are difficult to detach on their own, increasing the motor load and causing the motor to jam or even burn out. This limits the equipment's ability to process complex kitchen waste. Therefore, a household grinder with anti-clogging feeding is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a household food waste disposer with anti-clogging feeding mechanism, which solves the problem that when users put in a large amount or long strips of kitchen waste at once, the waste tends to accumulate and compact in the center of the feeding port, causing blockages.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a household pulverizer with anti-clogging feeding, comprising a grinding chamber, a water outlet pipe fixedly connected to the outside of the grinding chamber, a water inlet pipe fixedly connected to the outside of the grinding chamber, a metering mechanism provided at the top of the water inlet pipe, a self-compensating mechanism provided at the top of the metering mechanism, a dispersion mechanism provided inside the grinding chamber, a motor installed at the bottom of the grinding chamber, and a cutter disc fixedly connected to the drive end of the motor; The evacuation mechanism includes a fixed plate, the outer side of which is disposed on the inner wall of the grinding chamber. A spiral rod is rotatably connected to the top of the fixed plate, and a cone head is fixedly connected to the top of the spiral rod. A release component is disposed at the bottom of the cutter disc.

[0007] Preferably, the detachment assembly includes a bellows, the top end of which is fixedly connected to the bottom end of the cutter head, and an electric cylinder is provided inside the bellows, with a spring sleeved on the outer side of the drive end of the electric cylinder.

[0008] Preferably, the bottom end of the first spring abuts against the top end of the electric cylinder, and the top end of the first spring abuts against the bottom end of the cutter head.

[0009] Preferably, the metering mechanism includes a water wheel, which is disposed inside the water inlet pipe. A planetary gear set is disposed at the top of the water wheel. A metering chamber is fixedly connected to the output end of the planetary gear set. A housing is disposed on the outside of the planetary gear set. A single-hole partition is fixedly connected to the top of the housing. A feed pipe is fixedly connected to the bottom end of the single-hole partition.

[0010] Preferably, the self-repairing mechanism includes a single-hole partition plate II, the bottom end of which is disposed at the top of the quantitative hopper, a material hopper is fixedly connected to the top of the single-hole partition plate II, a lower pressure plate is slidably connected inside the material hopper, and a spring II is disposed inside the material hopper.

[0011] Preferably, the bottom end of the second spring abuts against the top end of the lower pressure plate, and the top end of the second spring abuts against the inner wall of the hopper.

[0012] Preferably, the silo contains an enzyme preparation, which is a complex enzyme comprising lipase, cellulase and protease.

[0013] Preferably, a sealing ring is fitted on the outer side of the lower pressure plate to prevent enzyme preparation leakage.

[0014] Preferably, the drive end of the motor is connected to the cutter head via a spline.

[0015] Preferably, the through hole of the second single-hole partition is offset from the direction of the feed pipe.

[0016] This invention provides a household grinder with anti-clogging feed. It has the following beneficial effects: 1. This invention features a dispersion mechanism consisting of a cone and a spiral rod at the feed inlet. The falling kitchen waste first contacts the cone, is actively dispersed, and evenly dispersed along the cone surface to prevent the material from accumulating and clogging in the center of the feed inlet. Combined with the impact of water on the inclined blades of the spiral rod, a rotational torque is generated under the action of gravity and impact force, causing the spiral rod to rotate autonomously. The dispersed material is then transported downward in an orderly manner along the spiral channel and smoothly enters the grinding chamber, achieving orderly conveying and initial dispersion of the material and preventing feed blockage.

[0017] 2. In this invention, water flows through the inlet pipe, driving the water wheel to rotate. The power of the water wheel is reduced by the planetary gear set, which drives the quantitative chamber to rotate slowly. When the independent chamber of the quantitative chamber rotates to align with the single-hole partition, the compound enzyme stored in the chamber falls into the inlet pipe through the feed pipe and enters the grinding chamber with the flowing water source, realizing the quantitative and timed release of the enzyme preparation, decomposing the residual oil, cellulose and protein inside the grinding chamber, preventing the pipe from solidifying and clogging, and reducing the entanglement of fibers on the blade disc.

[0018] 3. This invention utilizes the combined force of spring elasticity and material gravity to drive the lower pressure plate to continuously push enzyme powder towards the discharge port. When the cavity of the quantitative silo rotates to align with the through hole of the second single-hole partition, the enzyme powder automatically falls into the cavity under pressure for replenishment. The through hole of the second single-hole partition is offset from the direction of the discharge pipe, ensuring that the two are not in a continuous state with the quantitative silo at the same time, thus ensuring that replenishment and discharge do not interfere with each other. The sealing ring sleeved on the outside of the lower pressure plate prevents enzyme powder leakage, ensuring that the cavity of the quantitative silo can continuously receive enzyme powder replenishment and reducing the manual replenishment cycle.

[0019] 4. This invention connects the motor drive end to the cutter disc using a spline, enabling the cutter disc to float up and down. The electric cylinder drives the cutter disc to move up and down, and the axial displacement loosens and removes the plastic and debris wrapped around the cutter disc. The flexible corrugated pipe serves as an outer protection, and together with the springs, the cutter disc provides a reset function, causing the cutter disc to reciprocate during the floating process. Combined with the flushing effect of the high-pressure water flow inside the grinding chamber, the remaining plastic and debris are quickly carried out, achieving self-cleaning of the cutter disc and improving the equipment's ability to process plastic kitchen waste.

Detailed Implementation

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 4This invention provides a household food waste disposer with anti-clogging feeding mechanism, including a grinding chamber 1. The grinding chamber 1 serves as the main supporting structure, providing a closed and stable working space for grinding, mixing, and temporarily storing kitchen waste, preventing kitchen waste from splashing out and sewage from leaking, while also reducing operating noise. A water outlet pipe 2 is fixedly connected to the outside of the grinding chamber 1, connecting the bottom of the grinding chamber 1 to external drainage, providing a smooth discharge channel for the fine kitchen waste mixed with the enzymatic hydrolysis products, preventing kitchen waste from accumulating at the bottom of the chamber and causing odor, and ensuring continuous and stable operation of the equipment. A water inlet pipe 3 is fixedly connected to the outside of the grinding chamber 1, with one end connected to a household water inlet pipe. The tap water pipe leads directly to the inside of the grinding chamber 1 at the other end, providing a stable water flow during equipment operation. This helps to push the material downwards and flush the chamber wall, reducing material residue and adhesion. A metering mechanism 5 is installed at the top of the water inlet pipe 3. The metering mechanism 5 uses the water flow from the water inlet pipe 3 as a power source to realize the timed and quantitative dispensing of the compound enzyme preparation. This avoids waste caused by adding too much enzyme powder or insufficient enzyme addition, which would affect the decomposition effect and ensure continuous, stable and efficient enzymatic hydrolysis. A self-replenishing mechanism 6 is installed at the top of the metering mechanism 5. The self-replenishing mechanism 6 realizes automatic replenishment of the enzyme preparation, eliminating the need for frequent manual feeding, reducing maintenance frequency and improving ease of use.

[0024] The grinding chamber 1 is equipped with a dispersion mechanism 4, which is located at the core position directly below the feed inlet. The dispersion mechanism 4 uses a cone head 43 to divert and guide the flow of food waste through a spiral to prevent the accumulation and blockage of food waste, allowing the food waste to enter the grinding area in an orderly and stable manner. A motor 7 is fixedly installed at the bottom of the grinding chamber 1. As the core power component, the motor 7 provides a stable driving force for the high-speed rotation of the cutter disc 8, ensuring sufficient crushing and grinding force. The drive end of the motor 7 is fixedly connected to the cutter disc 8. The high-speed rotation of the cutter disc 8 forms a strong cutting and grinding action, which quickly crushes and refines the input food waste, allowing it to be discharged smoothly through the water outlet pipe 2, avoiding blockage of the pipe caused by large particles. The drive end of the motor 7 is connected to the cutter disc 8 through a spline. The spline connection structure allows the cutter disc 8 to float slightly in the axial direction, which does not affect the normal crushing operation and can also achieve untangling and loosening by floating up and down when entanglement occurs. Combined with the water flow flushing, it can quickly clean up debris and improve the equipment's anti-entanglement and anti-blockage capabilities.

[0025] Please see the appendix Figure 2 To be continued Figure 3The evacuation mechanism 4 includes a fixing plate 41, which is fixedly installed on the inner wall of the grinding chamber 1. The fixing plate 41 is centrally located and securely connected, providing a stable and reliable support point for the spiral rod 42, ensuring smooth rotation and long-term operation of the spiral rod 42. The outer side of the fixing plate 41 is tightly fitted to the inner wall of the grinding chamber 1. The top of the fixing plate 41 is rotatably connected to the spiral rod 42. Under the combined action of the gravity of the falling waste and the impact of the water flow from the inlet pipe 3, the spiral rod 42 rotates autonomously without additional power. When the spiral rod 42 rotates, it forms a smooth downward spiral channel, orderly guiding and dispersing the concentrated falling kitchen waste, preventing excessive accumulation of materials in certain areas and causing blockages. A cone head 43 is fixedly connected to the top of the feed inlet 2. The cone head 43 has a cone-shaped structure that is pointed at the top and wide at the bottom. It is located at the center of the feed inlet. When kitchen waste is put in from above, it first contacts the cone head 43. The cone surface disperses the concentrated falling material evenly in all directions to prevent it from accumulating in the center. This allows the material to enter the spiral rod 42 area in a dispersed state, further reducing the risk of blockage. The bottom of the cutter head 8 is equipped with a release component 44. By driving the cutter head 8 to float up and down in the axial direction, the flexible materials such as plastic wrapped around the cutter shaft and cutter head 8 can be quickly loosened and peeled off. This avoids long-term wrapping that leads to increased load and motor 7 overheating and shutdown failure, thus improving the equipment's ability to process complex kitchen waste.

[0026] Please see the appendix Figure 4 To be continued Figure 6 The detachment component 44 includes a bellows 441, which is made of a flexible, waterproof, and wear-resistant material, forming a closed and flexible protective structure. The bellows 441 can float up and down with the cutter disc 8 and freely extend and deform, which can prevent water, material debris, and oil from entering the electric cylinder 442, preventing short circuits, corrosion, and jamming, while not restricting the axial floating of the cutter disc 8, ensuring smooth untangling. The electric cylinder 442 is installed inside the bellows 441. The output end of the electric cylinder 442 is fixedly connected to the bottom of the cutter disc 8, controlling the up and down displacement of the cutter disc 8, so that the plastic and other wrapped materials on the cutter disc 8 can be detached. A spring 443 is sleeved on the outside of the drive end of the electric cylinder 442. The bottom end of the spring 443 is stably abutted against the top end of the electric cylinder 442, and the top end is stably abutted against the bottom end of the cutter disc 8. When the electric cylinder 442 retracts, it provides a uniform and gentle elastic restoring force, so that the cutter disc 8 can quickly and smoothly return to the normal working position, ensuring continuous crushing operation.

[0027] Please see the appendix Figure 7 To be continued Figure 9The quantitative mechanism 5 includes a water wheel 52, which is installed in the water flow channel inside the water inlet pipe 3. Under the continuous flow of tap water, it rotates autonomously, converting the water flow power into rotational mechanical energy. A planetary gear set 55 is installed at the top of the water wheel 52. The planetary gear set 55 converts the high rotational speed of the water wheel 52 into a low output speed, making the quantitative chamber 53 rotate more slowly and evenly, ensuring the proper dispensing of the enzyme preparation and preventing uncontrolled dispensing due to excessive speed. The output end of the planetary gear set 55 is fixedly connected to the quantitative chamber 53. The quantitative chamber 53 is evenly divided into multiple independent sealed chambers with the same capacity. Each chamber is specifically designed for single-quantity storage of the compound enzyme preparation, ensuring consistent enzyme quantity each time it is dispensed, achieving high-precision quantitative dispensing. The planetary gear set 55... An outer shell 51 is provided on the outside, which encloses the internal planetary gear set 55 to prevent the planetary gear set 55 from getting damp, water, or dust, and to ensure the stable operation of the planetary gear set 55. A single-hole partition 56 is fixedly connected to the top of the outer shell 51. The single-hole partition 56 has a discharge through hole, and the position of the through hole is aligned with the rotation path of the chamber of the quantitative chamber 53. When the chamber of the quantitative chamber 53 rotates to coincide with the through hole, the enzyme preparation flows out. It is in a closed state by default, realizing strict fixed-point quantitative control. A discharge pipe 54 is fixedly connected to the bottom of the single-hole partition 56. The upper end of the discharge pipe 54 is connected to the through hole of the single-hole partition 56, and the lower end is directly connected to the center of the water inlet pipe 3, so that the falling enzyme preparation falls into the center of the water flow, is evenly mixed with the water flow, and is then flushed into the grinding chamber 1.

[0028] Please see the appendix Figure 7 To be continued Figure 9The self-replenishing mechanism 6 includes a second single-hole partition 62, whose structure matches that of the first single-hole partition 56. It also has a feeding through-hole, the position of which is aligned with the rotation path of the quantitative chamber 53, but angularly offset from the through-hole of the discharge pipe 54. This ensures that feeding and discharge do not occur simultaneously, preventing cross-contamination, leakage, and excessive feeding. The bottom end of the second single-hole partition 62 is attached to the top end of the quantitative chamber 53, ensuring that it does not affect the normal rotation of the quantitative chamber 53 and that the enzyme preparation only falls when aligned. The top end of the second single-hole partition 62... A fixed connection is made to a hopper 61, which is a large-capacity cylindrical sealed storage cavity containing sufficient compound enzyme preparations to meet the needs of long-term continuous use and reduce the frequency of manual opening for adding and cleaning. A sliding lower pressure plate 64 is connected inside the hopper 61. The shape of the lower pressure plate 64 matches the internal aperture of the hopper 61, and under the combined action of gravity and elastic force, it always maintains a downward pressing state, continuously pushing the enzyme preparations towards the outlet to ensure that the outlet is always full of enzyme powder. A second spring 63 is installed inside the hopper 61. The top end of the device abuts against the inner top wall of the hopper 61, and the bottom end abuts against the top of the lower pressure plate 64, continuously providing gentle downward pressure to push the lower pressure plate 64 downward steadily, avoiding material shortages and ensuring the continuous and reliable self-replenishment function. The hopper 61 contains a compound enzyme preparation, including lipase, cellulase, and protease, which can decompose the grease and fibrous proteins in kitchen waste, making them less prone to coagulation and entanglement on the cutter disc 8, reducing the risk of pipe blockage and entanglement on the cutter disc 8, and also reducing odor generation. A sealing ring 65 is fixedly sleeved on the outer side of the lower pressure plate 64. The sealing ring 65 fits against the inner wall of the hopper 61, sealing the gap between the lower pressure plate 64 and the hopper 61, preventing enzyme powder from leaking upwards from the gap into the spring 63 area and causing jamming, thus ensuring the stable operation of the pushing mechanism. The through hole of the single-hole partition 62 and the through hole of the discharge pipe 54 are designed with a staggered layout, so that the feeding channel and the discharge channel are not connected to the quantitative hopper 53 at the same time, avoiding enzyme powder from falling directly from the feed hopper 61 into the water inlet pipe 3 and causing uncontrolled discharge, thus ensuring the quantitative dispensing of enzyme powder.

[0029] Working principle: A dispersion mechanism 4 is set at the feed inlet of the crusher. After the kitchen waste is put into the feed inlet, the falling kitchen waste is actively dispersed after contacting the cone head 43, and evenly dispersed to the surrounding area along the cone surface to avoid the material from accumulating in the center of the feed inlet and forming a blockage. Then, with the water source impacting the inclined surface of the blade of the screw rod 42, a rotational torque is generated under the action of gravity and impact force, causing the screw rod 42 to rotate autonomously. The dispersed material is conveyed downward along the spiral channel formed by the screw rod 42 and smoothly enters the grinding chamber 1, realizing the orderly conveying and initial dispersion of the material and preventing feed blockage.

[0030] A water inlet pipe 3 is connected to the outside of the grinding chamber 1. A metering mechanism 5 is installed at the top of the water inlet pipe 3. When water flows through the water inlet pipe 3, it drives the water wheel 52 inside the pipe to rotate. The power of the water wheel 52 is reduced by the planetary gear set 55 and then transmitted to the metering chamber 53, causing it to rotate slowly and synchronously. The inside of the metering chamber 53 is divided into multiple independent chambers. Each chamber stores a small amount of compound enzyme. The compound enzyme is a combination of lipase, cellulase and protease. When the chamber of the metering chamber 53 rotates to align with the single-hole partition 56, the feed pipe 54 is fixed at the bottom of the single-hole partition 56. The compound enzyme in the chamber falls into the water inlet pipe 3 through the feed pipe 54 and enters the grinding chamber 1 with the flowing water, realizing the quantitative and timed release of the enzyme preparation. The released compound enzyme will decompose the residual oil, cellulose and protein in the grinding chamber 1, prevent solidification and blockage of the pipe and reduce the entanglement of fibers on the blade disc 8, reduce the odor generated by kitchen waste residue, and improve grinding efficiency and equipment service life.

[0031] Sufficient compound enzymes are stored inside the hopper 61. The hopper 61 is equipped with a pushing structure consisting of a spring 63 and a pressure plate 64. Under the combined action of the spring force and the weight of the material, the pressure plate 64 continuously pushes the enzyme powder towards the outlet of the hopper 61. The outlet of the hopper 61 is connected to the chamber of the quantitative hopper 53 through a single-hole partition 62. When the empty chamber of the quantitative hopper 53 rotates to align with the through hole of the single-hole partition 62, the enzyme powder will automatically fall into the chamber under pressure for replenishment. The through hole of the single-hole partition 62 is offset from the direction of the feed pipe 54, so that the two are not in a continuous state with the quantitative hopper 53 at the same time. A sealing ring 65 is fitted on the outside of the pressure plate 64 to prevent enzyme powder from leaking into the top pushing mechanism, ensuring that the chamber of the quantitative hopper 53 can continuously receive enzyme powder replenishment and reducing the manual replenishment cycle.

[0032] Kitchen waste entering the grinding chamber 1 is pulverized and ground at high speed by the blade disc 8 driven by the motor 7. The ground material is discharged through the water outlet pipe 2. The drive end of the motor 7 is connected to the blade disc 8 through a spline, which can achieve slight up and down floating. The plastic wrapped around the motor 7 is detached by axial displacement. The blade disc 8 is driven up and down by the electric cylinder 442. The flexible corrugated pipe 441 serves as the outer protection. With the spring 443 resetting the top blade disc 8, the blade disc 8 floats and changes. Combined with the internal high-pressure water flow, the remaining plastic and debris are quickly flushed out, improving the equipment's processing of plastic kitchen waste.
