Description

Technical Field

[0001] This invention relates to the field of waste shredding technology, specifically an energy-saving shredder for kitchen waste disposal. Background Technology

[0002] Kitchen waste disposers are commonly used environmental protection equipment in modern homes and restaurants. Their core function is to pulverize kitchen waste and discharge it through the sewer to reduce the volume of waste and the frequency of cleaning. Existing kitchen waste disposers generally adopt a double-roller twisted structure, in which the blades on the two rollers bite and shear each other to break down the waste. However, the pulverizing rollers in the existing technology are usually rigidly installed, that is, both pulverizing rollers are fixed on the frame by bearing seats, which cannot produce any elastic displacement during the pulverizing process. This results in high energy consumption during the operation of the equipment, which makes it difficult to meet the requirements of energy-saving kitchens for low power consumption and high efficiency.

[0003] This rigid structure has obvious drawbacks in practical use: when encountering hard waste such as bones and fruit pits during the crushing process, the rigid crushing roller cannot buffer the impact load by yielding, which can easily lead to the breakage of the blades, deformation of the roller shaft, or even motor overload and jamming, affecting the service life and operational reliability of the equipment. At the same time, for soft waste such as vegetables and fruit peels, the rigid crushing roller lacks flexible buffering capacity and cannot adaptively adjust the biting force according to the characteristics of the waste, resulting in the soft waste being over-crushed. The motor is in a high-load state for a long time, which not only increases unnecessary energy consumption, but also aggravates the wear of the blade surface due to continuous strong shearing action, shortens the maintenance cycle, and further increases the overall operating cost of the energy-saving kitchen.

[0004] Therefore, we provide an energy-efficient kitchen waste shredder to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving shredder for kitchen waste disposal, so as to solve the problems mentioned in the background art.

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

[0007] An energy-saving kitchen waste shredder includes a machine body with a material guide trough installed inside the machine body. A mounting frame is installed on the machine body, and a rigid shredding roller and a flexible shredding roller arranged in parallel and penetrating the machine body are rotatably mounted on the mounting frame. The flexible shredding roller is slidably mounted on the mounting frame. Shredding blades for shredding waste are respectively installed on the rigid shredding roller and the flexible shredding roller. The rigid shredding roller and the flexible shredding roller are connected by a transmission component, so that when the flexible shredding roller rotates, it can drive the rigid shredding roller to rotate synchronously through the transmission component. The flexible crushing roller is provided with transmission shaft sleeves rotatably mounted on the mounting frame at both ends. A drive shaft and a driven sleeve are movably inserted into the transmission shaft sleeve. The drive shaft and the driven sleeve are engaged by a snap-fit ​​structure, so that when the driven sleeve rotates, the snap-fit ​​structure can drive the drive shaft to rotate synchronously. A flexible component is provided between the driven sleeve and the transmission shaft sleeve. The flexible component applies elastic force to the driven sleeve, so that the driven sleeve can always maintain a snap-fit ​​state with the drive shaft. A bearing seat is connected between the drive shaft and the flexible crushing roller. The driven sleeve and the transmission shaft sleeve are fitted by a keyway structure, so that when the transmission shaft sleeve rotates, it can drive the driven sleeve to rotate synchronously. The driven sleeve can slide axially relative to the transmission shaft sleeve. The drive shaft and the flexible crushing roller are fitted by a gear structure, so that when the drive shaft rotates, it can drive the flexible crushing roller to rotate synchronously.

[0008] An energy-saving kitchen waste shredder as described above: a geared motor is mounted on the mounting frame, and one of the drive shaft sleeves is mounted on the output end of the geared motor and driven to rotate by the geared motor.

[0009] As described above, an energy-saving kitchen waste shredder has two grooves on the mounting frame, which slide in cooperation with the two ends of the flexible shredding roller.

[0010] An energy-saving kitchen waste shredder as described above: the transmission assembly includes a drive arm and a driven arm. One end of the drive arm is rotatably mounted on a flexible shredding roller, and one end of the driven arm is rotatably mounted on a rigid shredding roller. The other end of the drive arm and the other end of the driven arm are hinged to each other. A drive gear is rotatably mounted on one end of the drive arm on the flexible shredding roller, and a driven gear is rotatably mounted on one end of the driven arm on the rigid shredding roller. An intermediate gear is rotatably mounted at the hinge point between the other end of the drive arm and the other end of the driven arm. The intermediate gear meshes with the drive gear. A reversing gear is rotatably mounted on the driven arm, and both sides of the reversing gear mesh with the intermediate gear and the driven gear, respectively.

[0011] As described above, an energy-saving kitchen waste shredder is provided: the keyway structure includes multiple flat keys that are equally spaced along the circumference of the driven sleeve and installed on the driven sleeve; multiple keyways that are equally spaced along the circumference of the drive shaft sleeve are provided on the drive shaft sleeve; and the flat keys slide in conjunction with the keyways.

[0012] An energy-saving kitchen waste shredder as described above: the snap-fit ​​structure includes a gentle snap-fit ​​block and a steep snap-fit ​​block installed at the end of the drive shaft; one end face of the driven sleeve is an inclined surface that fits against the surface of the gentle snap-fit ​​block; the driven sleeve has a gentle snap-fit ​​groove that movably engages with the gentle snap-fit ​​block; an inner snap-fit ​​seat is installed inside the driven sleeve; one end face of the inner snap-fit ​​seat is an inclined surface that fits against the surface of the steep snap-fit ​​block; the inner snap-fit ​​seat has a steep snap-fit ​​groove that movably engages with the steep snap-fit ​​block. The slope of the inclined surface at the end of the driven sleeve is less than the slope of the steep groove.

[0013] An energy-saving kitchen waste shredder as described above: the flexible component includes a telescopic guide rod, the two ends of which are respectively connected to the inner wall of the driven sleeve and the transmission shaft sleeve, and a buffer spring is sleeved on the outer periphery of the telescopic guide rod, the two ends of which are respectively connected to the inner wall of the driven sleeve and the transmission shaft sleeve.

[0014] An energy-saving kitchen waste shredder as described above: the gear structure includes a driving bevel gear mounted on a drive shaft and a driven bevel gear mounted on a flexible shredding roller, wherein the driven bevel gear meshes with the driving bevel gear.

[0015] An energy-saving kitchen waste shredder as described above: the top of the machine body is hinged with a cover plate.

[0016] An energy-saving kitchen waste shredder as described above: the bottom of the machine body is equipped with a discharge pipe that communicates with the inside of the machine body.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a flexible component, the driven sleeve can slide axially within the transmission shaft sleeve and maintain a snap-fit ​​state with the drive shaft. When the crushing roller encounters hard waste such as bones or fruit pits, the driven sleeve can overcome the elasticity of the flexible component and slide backward, driving the drive shaft and the flexible crushing roller to move backward together. This increases the interlocking gap between the two rollers instantaneously, allowing the hard waste to pass through smoothly without getting stuck. This effectively avoids the risks of blade breakage, roller deformation, and motor overload burnout, and effectively improves the working reliability and service life of the equipment. Furthermore, this invention creates a two-stage flexible buffer mechanism by setting the slope of the driven sleeve end to be less than that of the steep groove. When processing soft waste such as vegetables and fruit peels, the gentler block only contacts the slope of the driven sleeve end, resulting in less pressure on the flexible component and providing a first-stage flexible buffer, allowing the soft waste to be moderately crushed without over-crushing. When processing hard waste such as bones, the steeper block further engages inside the steep groove, resulting in greater compression of the flexible component and providing a second-stage flexible buffer, enabling the hard waste to be effectively crushed as well. This adaptive, graded buffer structure allows the crushing roller to automatically adjust its biting force and flexibility according to the hardness of the waste, avoiding over-crushing of soft waste and long-term high-load operation of the motor, effectively reducing energy consumption. It also reduces unnecessary wear on the blade surface, extends the maintenance cycle, and lowers the overall operating cost of the energy-efficient kitchen. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1-10 As an embodiment of the present invention, an energy-saving kitchen waste shredder includes a body 1, a guide trough 2 installed inside the body 1, a mounting frame 3 installed on the body 1, and a rigid shredding roller 4 and a flexible shredding roller 5 arranged in parallel and penetrating the body 1 rotatably mounted on the mounting frame 3. The flexible shredding roller 5 is slidably mounted on the mounting frame 3. Shredding blades 6 for shredding waste are respectively installed on the rigid shredding roller 4 and the flexible shredding roller 5. The rigid shredding roller 4 and the flexible shredding roller 5 are connected by a transmission component, so that when the flexible shredding roller 5 rotates, it can drive the rigid shredding roller 4 to rotate synchronously through the transmission component. The flexible crushing roller 5 has a drive shaft sleeve 13 rotatably mounted on the mounting frame 3 at both ends. A drive shaft 14 and a driven sleeve 18 are movably inserted into the drive shaft sleeve 13. The drive shaft 14 and the driven sleeve 18 are engaged by a snap-fit ​​structure, so that when the driven sleeve 18 rotates, it can drive the drive shaft 14 to rotate synchronously through the snap-fit ​​structure. A flexible component is provided between the driven sleeve 18 and the drive shaft sleeve 13. The flexible component applies elastic force to the driven sleeve 18, so that the driven sleeve 18 can always maintain a snap-fit ​​state with the drive shaft 14. A bearing seat 15 is connected between the drive shaft 14 and the flexible crushing roller 5. The driven sleeve 18 and the transmission shaft sleeve 13 are connected by a keyway structure, so that when the transmission shaft sleeve 13 rotates, it can drive the driven sleeve 18 to rotate synchronously. The driven sleeve 18 can slide axially relative to the transmission shaft sleeve 13. The drive shaft 14 and the flexible crushing roller 5 are connected by a gear structure, so that when the drive shaft 14 rotates, it can drive the flexible crushing roller 5 to rotate synchronously through the gear structure.

[0031] In this embodiment, during use, the transmission shaft sleeve 13 is driven to rotate by an external drive device. The transmission shaft sleeve 13 drives the driven sleeve 18 to rotate synchronously through a keyway structure. The driven sleeve 18 drives the drive shaft 14 to rotate synchronously through a snap-fit ​​structure. The drive shaft 14 drives the flexible crushing roller 5 to rotate synchronously through a gear structure. The flexible crushing roller 5 drives the rigid crushing roller 4 to rotate synchronously through a transmission assembly. This achieves the crushing teeth 6 on the rigid crushing roller 4 and the flexible crushing roller 5 to crush the waste. After being guided by the guide chute 2, the waste falls into the crushing teeth 6 between the rigid crushing roller 4 and the flexible crushing roller 5, where it is sheared and crushed by the rotating crushing teeth 6. During the crushing process, when encountering hard objects such as bones and fruit pits... When hard waste is being crushed, the waste exerts a reverse thrust on the flexible crushing roller 5, causing the flexible crushing roller 5 to slide along the mounting frame 3. At the same time, it drives the drive shaft 14 and the driven sleeve 18 to move away from the rigid crushing roller 4. The meshing gap between the two rollers increases, allowing hard waste to pass through without getting stuck. During this process, the driven sleeve 18 overcomes the elastic force of the flexible component and slides axially relative to the drive shaft sleeve 13. However, due to the existence of the snap-fit ​​structure, the driven sleeve 18 and the drive shaft 14 always remain in a snap-fit ​​state, and the power transmission is not interrupted. When the hard waste passes through, the elastic force of the flexible component pushes the driven sleeve 18 to reset, driving the drive shaft 14 and the flexible crushing roller 5 back to the initial position and restoring the normal crushing gap.

[0032] As a further embodiment of the present invention, a geared motor 28 is mounted on the mounting bracket 3, and one of the transmission shaft sleeves 13 is mounted on the output end of the geared motor 28 and driven to rotate by the geared motor 28.

[0033] In this embodiment, the output end of the geared motor 28 is directly connected to one of the transmission shaft sleeves 13, providing rotational power to the transmission shaft sleeve 13 on that side. After the geared motor 28 is started to drive the transmission shaft sleeve 13 to rotate, it drives the flexible crushing roller 5 to rotate in sequence through the keyway structure, snap-fit ​​structure, gear structure and transmission assembly, thereby cooperating with the rigid crushing roller 4 to achieve the crushing operation.

[0034] As a further embodiment of the present invention, the mounting frame 3 has two sliding grooves 7, which are respectively slidably engaged with the two ends of the flexible crushing roller 5.

[0035] In this embodiment, two grooves 7 are located at both ends of the flexible crushing roller 5 and slide in cooperation with both ends of the flexible crushing roller 5. When the flexible crushing roller 5 is subjected to the reverse thrust of hard waste, the flexible crushing roller 5 can slide along the grooves 7 in a direction away from the rigid crushing roller 4, ensuring that the process of increasing the gap between the two rollers is smooth and the position movement is not biased, while providing guidance for the reset of the flexible crushing roller 5.

[0036] As a further embodiment of the present invention, the transmission assembly includes a drive arm 8 and a driven arm 9. One end of the drive arm 8 is rotatably mounted on a flexible crushing roller 5, and one end of the driven arm 9 is rotatably mounted on a rigid crushing roller 4. The other end of the drive arm 8 and the other end of the driven arm 9 are hinged to each other. A drive gear 11 is rotatably mounted on one end of the drive arm 8 on the flexible crushing roller 5, and a driven gear 12 is rotatably mounted on one end of the driven arm 9 on the rigid crushing roller 4. An intermediate gear 10 is rotatably mounted at the hinge point between the other end of the drive arm 8 and the other end of the driven arm 9. The intermediate gear 10 meshes with the drive gear 11. A reversing gear 31 is rotatably mounted on the driven arm 9, and the two sides of the reversing gear 31 mesh with the intermediate gear 10 and the driven gear 12, respectively.

[0037] In this embodiment, when the flexible crushing roller 5 moves, it drives the drive arm 8 to swing. The drive arm 8 drives the driven arm 9 to swing through the hinge point. When the flexible crushing roller 5 rotates, it drives the drive gear 11 to rotate. The drive gear 11 rotates, which drives the intermediate gear 10 to rotate. The intermediate gear 10 rotates, which drives the reversing gear 31 to rotate. The reversing gear 31 rotates, which drives the driven gear 12 to rotate. This, in turn, drives the rigid crushing roller 4 to rotate synchronously in the opposite direction. Through the synchronous reverse rotation of the flexible crushing roller 5 and the rigid crushing roller 4, the crushing blades 6 crush the waste. During the process of the flexible crushing roller 5 sliding backward along the mounting frame 3, the transmission assembly can still maintain the continuity of power transmission through the hinge structure of the drive arm 8 and the driven arm 9 and the gear meshing, ensuring that the two rollers always rotate synchronously in the opposite direction.

[0038] As a further embodiment of the present invention, the keyway structure includes a plurality of flat keys 22 installed on the driven sleeve 18 and distributed at equal angular intervals along the circumference of the driven sleeve 18, and a plurality of keyways 21 distributed at equal angular intervals along the circumference of the drive shaft sleeve 13 are provided on the drive shaft sleeve 13, and the flat keys 22 and the keyways 21 are slidably engaged.

[0039] In this embodiment, multiple flat keys 22 and keyways 21 are slidably engaged in a one-to-one correspondence, so that when the drive shaft sleeve 13 rotates, it can reliably drive the driven sleeve 18 to rotate synchronously, while allowing the driven sleeve 18 to slide freely along the axial direction of the drive shaft sleeve 13, thereby achieving decoupling of power transmission and axial retraction.

[0040] As a further embodiment of the present invention, the snap-fit ​​structure includes a smooth snap-fit ​​block 24 and a steep snap-fit ​​block 25 installed at the end of the drive shaft 14. One end face of the driven sleeve 18 is an inclined surface that fits against the surface of the smooth snap-fit ​​block 24. A smooth snap-fit ​​groove 27 is provided on the driven sleeve 18 to be movably fitted with the smooth snap-fit ​​block 24. An inner snap-fit ​​seat 23 is installed inside the driven sleeve 18. One end face of the inner snap-fit ​​seat 23 is an inclined surface that fits against the surface of the steep snap-fit ​​block 25. A steep snap-fit ​​groove 26 is provided on the inner snap-fit ​​seat 23 to be movably fitted with the steep snap-fit ​​block 25. Among them, the slope of the inclined surface at the end of the driven sleeve 18 is less than the slope of the steep groove 26.

[0041] In this embodiment, the snap-fit ​​structure realizes the torque transmission and graded buffering functions between the drive shaft 14 and the driven sleeve 18. The gentle snap-fit ​​block 24 fits against the gentle slope at the end of the driven sleeve 18 to form the first-level snap-fit. When the driven sleeve 18 rotates, it can drive the drive shaft 14 to rotate. The steep snap-fit ​​block 25 fits against the steep groove 26 on the inner snap-fit ​​seat 23 to form the second-level snap-fit. Since the slope of the end slope of the driven sleeve 18 is less than the slope of the steep groove 26, when crushing vegetables and other waste, it is only necessary to snap-fit ​​the gentle snap-fit ​​block 24 with the end face of the driven sleeve 18. When the drive shaft 14 rotates and is subjected to axial thrust, the gentle snap-fit ​​block 24 first slides along the gentle slope, and then... The component is slightly compressed, providing a first-level flexible buffer. When crushing hard waste such as bones, the thrust increases, rotating the drive shaft 14 and engaging the steep locking block 25 into the steep locking groove 26. The smooth locking block 24 is embedded into the smooth locking groove 27. At this time, the buffer spring 20 is further compressed, and the biting force between the drive shaft 14 and the driven sleeve 18 also increases. When the drive shaft 14 rotates and is subjected to axial thrust, the smooth locking block 24 slides along the steep slope of the steep locking groove 26, providing a second-level flexible buffer. This structure achieves the effect of automatically adjusting the buffering force according to the hardness of the waste, avoiding the problem of accelerated wear of the blades and high power consumption caused by continuously using a high-flexibility buffer structure.

[0042] As a further embodiment of the present invention, the flexible component includes a telescopic guide rod 19, the two ends of which are respectively connected to the inner walls of the driven sleeve 18 and the transmission shaft sleeve 13, and a buffer spring 20 is sleeved on the outer periphery of the telescopic guide rod 19, the two ends of which are respectively connected to the inner walls of the driven sleeve 18 and the transmission shaft sleeve 13.

[0043] In this embodiment, the telescopic guide rod 19 serves as a guide and support, ensuring that the driven sleeve 18 moves smoothly and without wobbling during axial sliding. The buffer spring 20 is sleeved on the outer periphery of the telescopic guide rod 19, providing the main elastic restoring force. When the driven sleeve 18 is subjected to axial thrust, the buffer spring 20 is compressed and stores energy. When the thrust disappears, the buffer spring 20 releases its elastic force to push the driven sleeve 18 back to its original position. Together, they constitute a flexible component. The telescopic guide rod 19 ensures the accuracy of the movement direction, and the buffer spring 20 provides the elastic force required for buffering and resetting, ensuring that the driven sleeve 18 is subjected to uniform force and moves smoothly during axial sliding.

[0044] As a further embodiment of the present invention, the gear structure includes a driving bevel gear 17 mounted on the drive shaft 14 and a driven bevel gear 16 mounted on the flexible crushing roller 5, wherein the driven bevel gear 16 meshes with the driving bevel gear 17.

[0045] In this embodiment, the driving bevel gear 17 and the driven bevel gear 16 mesh with each other. When the drive shaft 14 rotates, the flexible crushing roller 5 is driven to rotate synchronously through the meshing of the driving bevel gear 17 and the driven bevel gear 16, thereby realizing the transmission of power from the drive shaft 14 to the flexible crushing roller 5.

[0046] As a further embodiment of the present invention, a cover plate 29 is hinged to the top of the body 1.

[0047] In this embodiment, the cover plate 29 is used to close the upper opening of the crushing chamber. When in use, the cover plate 29 is opened to put in the garbage. During the crushing process, the cover plate 29 is closed to prevent the garbage from splashing. It also serves as sound insulation and safety protection.

[0048] As a further embodiment of the present invention, a discharge pipe 30 communicating with the interior of the machine body 1 is installed at the bottom of the machine body 1.

[0049] In this embodiment, the discharge pipe 30 is connected to the inside of the crushing chamber. The garbage particles crushed by the crushing blades 6 fall under the action of gravity and are discharged into the sewer or collection container through the discharge pipe 30, thus completing the entire crushing process.

[0050] The working principle of this invention is as follows: When in use, the geared motor 28 is started to drive one of the transmission shaft sleeves 13 to rotate. The transmission shaft sleeve 13 drives the driven sleeve 18 to rotate synchronously through the keyway structure. The driven sleeve 18 drives the drive shaft 14 to rotate synchronously through the snap-fit ​​structure. The drive shaft 14 drives the flexible crushing roller 5 to rotate synchronously through the gear structure. The flexible crushing roller 5 drives the rigid crushing roller 4 to rotate synchronously in the opposite direction through the transmission assembly, thereby realizing that the crushing blades 6 on the rigid crushing roller 4 and the flexible crushing roller 5 shear and crush the garbage. Specifically, after being guided by the feed chute 2, the waste falls into the crushing teeth 6 between the rigid crushing roller 4 and the flexible crushing roller 5. The rotating crushing teeth 6 shear and crush the waste. The power transmission path of the transmission component is as follows: when the flexible crushing roller 5 rotates, it drives the drive gear 11 to rotate. The drive gear 11 drives the intermediate gear 10 to rotate. The intermediate gear 10 drives the reversing gear 31 to rotate. The reversing gear 31 drives the driven gear 12 to rotate, which in turn drives the rigid crushing roller 4 to rotate synchronously in the opposite direction. At the same time, when the flexible crushing roller 5 slides along the slide groove 7, it drives the drive arm 8 to swing. The drive arm 8 drives the driven arm 9 to swing through the hinge point. This linkage structure ensures that the flexible crushing roller 5 can still maintain synchronous reverse operation with the rigid crushing roller 4 during the sliding process. During the crushing process, when encountering soft waste such as vegetables and fruit peels, only one level of flexible buffering is needed to complete the crushing. At this time, the smooth locking block 24 fits and engages with the smooth inclined surface at the end of the driven sleeve 18, forming the first-level engagement state. When the drive shaft 14 rotates and is subjected to axial thrust, the smooth locking block 24 slides along the smooth inclined surface, and the buffer spring 20 in the flexible component is slightly compressed, providing a first-level strength of flexible buffering. This buffering force is small and sufficient to absorb the slight impact during the crushing process of soft waste, so that the soft waste is moderately crushed without being over-crushed, while avoiding long-term high-load operation of the motor and reducing energy consumption. When encountering hard waste such as bones and fruit pits, the waste exerts a large reverse thrust on the flexible crushing roller 5, causing the flexible crushing roller 5 to slide away from the rigid crushing roller 4 along the slide groove 7. At the same time, it drives the drive shaft 14 and the driven sleeve 18 to move away from the rigid crushing roller 4 together, increasing the meshing gap between the two rollers. During this process, the thrust further increases, causing the drive shaft 14 to rotate and the steep locking block 25 to be locked into the steep locking groove 26. At the same time, the gentle locking block 24 is embedded into the gentle locking groove 27, forming a second-level locking state. At this time, the buffer spring 20 is further compressed, and the meshing force between the drive shaft 14 and the driven sleeve 18 also increases. When the drive shaft 14 rotates and is subjected to axial thrust, the gentle locking block 24 slides along the steep slope of the steep locking groove 26, providing a second-level flexible buffer. This buffer force is large and can effectively absorb the large impact load during the crushing process of hard waste, allowing the hard waste to pass smoothly without getting stuck. This effectively avoids the risks of blade breakage, roller deformation, and motor overload burnout. During the two-stage buffering process described above, due to the presence of the snap-fit ​​structure, the driven sleeve 18 and the drive shaft 14 remain in a snap-fit ​​state, ensuring uninterrupted power transmission. The flat key 22 and keyway 21 in the keyway structure slide together to ensure that the driven sleeve 18 can reliably rotate synchronously when the drive shaft sleeve 13 rotates, while allowing the driven sleeve 18 to slide freely along the axial direction, thus decoupling power transmission and axial retraction. The telescopic guide rod 19 in the flexible component plays a guiding and supporting role, ensuring that the driven sleeve 18 moves smoothly and without wobbling when sliding axially. The buffer spring 20 provides elastic restoring force. When the driven sleeve 18 is subjected to axial thrust, it is compressed and stores energy. When the thrust disappears, the elastic force is released to push the driven sleeve 18 to reset. After crushing, the garbage particles fall under the influence of gravity and are discharged into the sewer or collection container through the discharge pipe 30, completing the entire crushing process. Throughout the operation, the cover plate 29 is used to seal the upper opening of the crushing chamber to prevent garbage from splashing, and also serves as sound insulation and safety protection.

[0051] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
