Pulverization module and pulverization method

Abstract

The present disclosure provides a pulverizing module and a pulverizing method. The pulverizing module comprises a pulverizing bin, a first grinding part and a second grinding part. The pulverizing bin is provided with a mounting cavity and a discharge hole, and the first grinding part is arranged in the mounting cavity. The second grinding part is arranged in the mounting cavity and is arranged opposite to the first grinding part and can rotate relative to the first grinding part. The distance between the second grinding part and the first grinding part is adjustable, and a pulverizing area is formed between the second grinding part and the first grinding part, and the pulverizing area is in communication with the discharge hole. In the grinding process, hard objects in the garbage will move with the grinding force, so that the hard objects have a grinding effect on the hair and have a hair pulverizing effect. Since the powder can be discharged through the discharge hole, the adjustment of the distance between the first grinding part and the second grinding part is avoided after the powder is accumulated, so that the distance between the first grinding part and the second grinding part can be smaller than the diameter of the hair, and the first grinding part and the second grinding part can also grind the hair into powder.

Description

Technical Field

[0001] This disclosure relates to the technical field of cleaning equipment, and in particular to a pulverizing module and pulverizing method. Background Technology

[0002] Cleaning equipment such as robotic vacuum cleaners suck up garbage into the dust collection box during the cleaning process. After completing the cleaning task, the cleaning equipment returns to the base station. The base station uses negative pressure suction to transfer the garbage in the dust collection box to the installation cavity. Then, the shredding module is activated to crush the garbage. After shredding, water is injected into the installation cavity to mix the crushed garbage with water to form sewage. Finally, the sewage is discharged through the sewage channel, which can be the outlet of the shredding module, a sewer, etc.

[0003] However, hair is often mixed in with ground waste, and the relevant shredding module cuts the hair by rotating blades. Due to the good toughness and ductility of hair, although the blades can cut it into small pieces, they cannot pulverize it into powder. Unshredded hair easily tangles or adheres to the inner wall of the sewage channel during the sewage discharge process, resulting in poor sewage discharge and easy blockage of the sewage channel.

[0004] It should be noted that the information disclosed in the background section above is intended to enhance the understanding of the background of this disclosure, and therefore may contain information that does not constitute prior art. Summary of the Invention

[0005] The purpose of this disclosure is to overcome at least one of the above-mentioned technical defects and to provide a pulverizing module and pulverizing method that achieves hair pulverization through grinding, improves the smoothness of sewage discharge, and inhibits the blockage of sewage discharge channels.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] In a first aspect, embodiments of this disclosure provide a crushing module, comprising:

[0008] The crushing chamber is equipped with an installation cavity and a discharge port;

[0009] A first grinding element is disposed within the mounting cavity; and

[0010] The second grinding element is disposed in the mounting cavity and is arranged opposite to the first grinding element and can rotate relative to it. The distance between the second grinding element and the first grinding element is adjustable. A pulverizing zone is formed between the second grinding element and the first grinding element, and the pulverizing zone is connected to the discharge hole.

[0011] In some embodiments, the crushing module further includes a cutting tool rotatably disposed within the crushing zone.

[0012] In some embodiments, the second grinding element is provided with a mounting hole, the cutting tool is rotatably disposed in the mounting hole and at least partially located in the grinding zone, and the cutting tool can retract into the mounting hole.

[0013] In some embodiments, the discharge hole includes an indirect discharge hole, the second grinding element is provided with a connecting hole, the crushing zone, the mounting hole, the connecting hole and the indirect discharge hole are connected in sequence, and the cutting tool scrapes the crushed material in the mounting hole into the connecting hole when it rotates.

[0014] In some embodiments, the cutting tool is rotatably connected to the second grinding member, causing the cutting tool to rotate; the second grinding member is rotatably disposed within the mounting cavity, causing the cutting tool to also revolve around the rotation center of the second grinding member.

[0015] In some embodiments, the center of rotation of the second grinding element passes through the cutting range of the cutting tool; and / or,

[0016] The cutting range of the cutting tool covers the outer circumference of the second grinding workpiece.

[0017] In some embodiments, the discharge port includes an indirect discharge port, and the first grinding element and / or the second grinding element are provided with a connecting hole, wherein the pulverizing zone, the connecting hole, and the indirect discharge port are sequentially connected; and / or,

[0018] The discharge port includes a direct discharge port, which is connected to the bottom of the crushing zone and is located on the outer periphery of the crushing zone.

[0019] In some embodiments, the first grinding element or the second grinding element includes: a base disposed in the mounting cavity, an elastic buffer, and a movable grinding disc;

[0020] The elastic buffer is connected to the base and the movable grinding disc respectively. The elastic buffer is compressed during grinding, and the movable grinding disc is used to grind the waste.

[0021] Secondly, this disclosure provides a pulverizing method, which uses a pulverizing module from any of the above embodiments for pulverizing, the pulverizing method comprising:

[0022] S101. Control the first grinding element and the second grinding element to rotate relative to each other;

[0023] S103. Control the distance between the first grinding element and the second grinding element to decrease, and obtain the grinding pressure;

[0024] S105. When the grinding pressure is equal to the preset pressure, control the distance between the first grinding element and the second grinding element to stop decreasing;

[0025] S107. When the grinding pressure is less than the preset pressure, return to step S103.

[0026] In some embodiments, in step S107, when the duration of the grinding pressure equal to the preset pressure is greater than the preset duration, the first grinding element and the second grinding element are controlled to stop rotating relative to each other, and the distance between the first grinding element and the second grinding element is adjusted to the initial distance; and / or,

[0027] After step S103, the pulverizing method further includes: S104, obtaining the reduction value of the distance between the first grinding piece and the second grinding piece in real time, and when the reduction amount of the distance is equal to the preset reduction value, controlling the first grinding piece and the second grinding piece to stop rotating relative to each other, and adjusting the distance between the first grinding piece and the second grinding piece to the initial distance.

[0028] Compared with the prior art, this disclosure has at least the following advantages:

[0029] The aforementioned pulverizing module contains waste in the pulverizing zone, and the waste can be pulverized during the relative rotation of the first and second grinding parts. The distance between the first and second grinding parts is adjustable. During the pulverizing process, the distance between the first and second grinding parts gradually decreases, so that the distance between them is adapted to the volume of the waste, thereby maintaining the pulverizing pressure at the preset pressure and improving the pulverizing efficiency.

[0030] Since the garbage usually contains hard objects such as wood chips, gravel, and stones, during the relative rotation of the first and second grinding parts, the hard objects in the garbage will move with the grinding force, so that the hard objects have a grinding effect on the hair, and then the hard objects grind the hair into powder, which can achieve the effect of crushing the hair, improving the smoothness of sewage discharge and inhibiting the blockage of sewage channels.

[0031] Since the discharge hole is connected to the grinding zone, the powder generated during the grinding process can be discharged through the discharge hole to avoid the powder from accumulating and hindering the adjustment of the distance between the first grinding piece and the second grinding piece. This allows the distance between the first grinding piece and the second grinding piece to be smaller than the diameter of a hair, so that the first grinding piece and the second grinding piece can also grind the hair into powder, achieving the effect of crushing the hair, improving the smoothness of sewage discharge, and inhibiting the blockage of the sewage discharge channel.

[0032] In the above-described pulverization method, during the grinding process, the distance between the first and second grinding elements is controlled to decrease, and grinding pressure is acquired. When the grinding pressure equals a preset pressure, the distance between the first and second grinding elements is stopped from decreasing. When the grinding pressure is less than the preset pressure, the distance between the first and second grinding elements is controlled to decrease again. Thus, by acquiring and adjusting the grinding pressure, the grinding pressure is maintained at the preset pressure, improving grinding efficiency and consequently, pulverization efficiency.

Detailed Implementation

[0043] To facilitate understanding of this disclosure, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this disclosure are shown in the drawings. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide the reader with a more thorough and complete understanding.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] As described in the background section, cleaning equipment such as robotic vacuum cleaners sucks garbage into a dust collection box during the cleaning process. After completing the cleaning task, the cleaning equipment returns to the base station, which uses negative pressure suction to transfer the garbage in the dust collection box to the installation cavity. Then, the shredding module is activated to crush the garbage. After shredding, water is injected into the installation cavity to mix the crushed garbage with the water to form wastewater. Finally, the wastewater is discharged through a sewage channel, which can be the outlet of the shredding module, a sewer, or the like.

[0047] However, hair is often mixed in with ground waste, and the relevant shredding module cuts the hair by rotating blades. Due to the good toughness and ductility of hair, although the blades can cut it into small pieces, they cannot pulverize it into powder. Unshredded hair easily tangles or adheres to the inner wall of the sewage channel during the sewage discharge process, resulting in poor sewage discharge and easy blockage of the sewage channel.

[0048] To overcome at least one of the above-mentioned technical defects, this disclosure provides a pulverizing module, including a pulverizing chamber, a first grinding element, and a second grinding element. The pulverizing chamber has an installation cavity and a discharge hole, and the first grinding element is disposed in the installation cavity. The second grinding element is disposed in the installation cavity and is arranged opposite to the first grinding element and can rotate relative to it. The distance between the second grinding element and the first grinding element is adjustable, and a pulverizing zone is formed between the second grinding element and the first grinding element. The pulverizing zone is connected to the discharge hole.

[0049] The aforementioned pulverizing module contains waste in the pulverizing zone, and the waste can be pulverized during the relative rotation of the first and second grinding parts. The distance between the first and second grinding parts is adjustable. During the pulverizing process, the distance between the first and second grinding parts gradually decreases, so that the distance between them is adapted to the volume of the waste, thereby maintaining the pulverizing pressure at the preset pressure and improving the pulverizing efficiency.

[0050] Since the garbage usually contains hard objects such as wood chips, gravel, and stones, during the relative rotation of the first and second grinding parts, the hard objects in the garbage will move with the grinding force, so that the hard objects have a grinding effect on the hair, and then the hard objects grind the hair into powder, which can achieve the effect of crushing the hair, improving the smoothness of sewage discharge and inhibiting the blockage of sewage channels.

[0051] Since the discharge hole is connected to the grinding zone, the powder generated during the grinding process can be discharged through the discharge hole to avoid the powder from accumulating and hindering the adjustment of the distance between the first grinding piece and the second grinding piece. This allows the distance between the first grinding piece and the second grinding piece to be smaller than the diameter of a hair, so that the first grinding piece and the second grinding piece can also grind the hair into powder, achieving the effect of crushing the hair, improving the smoothness of sewage discharge, and inhibiting the blockage of the sewage discharge channel.

[0052] This disclosure also provides a pulverizing method, which uses the above-mentioned pulverizing module for pulverizing. The pulverizing method includes: S101, controlling the first grinding element and the second grinding element to rotate relative to each other; S103, controlling the distance between the first grinding element and the second grinding element to decrease and obtaining grinding pressure; S105, when the grinding pressure is equal to the preset pressure, controlling the distance between the first grinding element and the second grinding element to stop decreasing; S107, when the grinding pressure is less than the preset pressure, returning to step S103.

[0053] In the above-described pulverization method, during the grinding process, the distance between the first and second grinding elements is controlled to decrease, and grinding pressure is acquired. When the grinding pressure equals a preset pressure, the distance between the first and second grinding elements is stopped from decreasing. When the grinding pressure is less than the preset pressure, the distance between the first and second grinding elements is controlled to decrease again. Thus, by acquiring and adjusting the grinding pressure, the grinding pressure is maintained at the preset pressure, improving grinding efficiency and consequently, pulverization efficiency.

[0054] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0055] like Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a pulverizing module 10, including a pulverizing chamber 110, a first grinding element 130, and a second grinding element 150. The pulverizing chamber 110 is provided with a mounting cavity 111 and a discharge hole 113, and the discharge hole 113 is connected to the mounting cavity 111.

[0056] A first grinding element 130 and a second grinding element 150 are disposed within the mounting cavity 111. The first grinding element 130 and the second grinding element 150 are arranged opposite each other and are rotatable relative to each other. The distance between the first grinding element 130 and the second grinding element 150 is adjustable, meaning the grinding thickness between them is adjustable. This allows the space within the pulverizing zone 115 to be adjusted according to the volume of the waste, thereby maintaining the grinding pressure of the first grinding element 130 and the second grinding element 150 at a preset pressure. A pulverizing zone 115 is formed between the first grinding element 130 and the second grinding element 150, which is used to hold the waste. The first grinding element 130 and the second grinding element 150 grind the waste together when rotating relative to each other. The pulverizing zone 115 is connected to a discharge hole 113, which is used to discharge the pulverized powder.

[0057] It can be understood that "the grinding pressure is maintained at the preset pressure" can mean that the preset pressure is maintained throughout the grinding process; or it can mean that the preset pressure is maintained intermittently during the grinding process, for example, maintaining the preset pressure for 1 minute and then stopping; stopping for 10 seconds and then maintaining the preset pressure for 1 minute again, and so on until the machine stops or for a certain period of time.

[0058] In this embodiment, the working principle of the crushing module 10 is as follows:

[0059] 1. Preparation stage: The distance between the first grinding part 130 and the second grinding part 150 is at its maximum value, and both the first grinding part 130 and the second grinding part 150 are stationary.

[0060] 2. Feeding stage: Waste enters the crushing zone 115 through the feed hole (not shown in the figure). Waste can be sucked into the crushing zone 115 by negative pressure, or it can be manually poured into the crushing zone 115. When feeding by negative pressure, the discharge hole 113 is closed.

[0061] 3. Crushing stage: The feed hole is closed, and the discharge hole 113 is in an open state or intermittently open state, so that the powder formed by crushing can be discharged through the discharge hole 113; the first grinding piece 130 and the second grinding piece 150 rotate relative to each other to grind the waste in the crushing zone 115. After grinding and cutting, the waste gradually becomes finer, so that its volume gradually decreases, and the powder formed by crushing can be discharged through the discharge hole 113. Therefore, during the grinding and cutting process, the distance between the first grinding piece 130 and the second grinding piece 150 is gradually reduced to keep the grinding pressure at the preset pressure, so as to improve the grinding efficiency and cutting effect.

[0062] The aforementioned pulverizing module contains waste in the pulverizing zone 115, which can grind the waste during the relative rotation of the first grinding element 130 and the second grinding element 150. The distance between the first grinding element 130 and the second grinding element 150 is adjustable. During the grinding process, the distance between the first grinding element 130 and the second grinding element 150 gradually decreases, so that the distance between the two is adapted to the volume of the waste, thereby maintaining the grinding pressure at the preset pressure and improving the grinding efficiency.

[0063] Since the garbage usually contains hard objects such as wood chips, gravel, and stones, during the relative rotation of the first grinding part 130 and the second grinding part 150, the hard objects in the garbage will move with the grinding force, so that the hard objects have a grinding effect on the hair, and then the hard objects grind the hair into powder, which can achieve the effect of crushing the hair, improving the smoothness of sewage discharge and inhibiting the blockage of sewage discharge channels.

[0064] Since the discharge hole 113 is connected to the grinding zone 115, the powder generated during the grinding process can be discharged through the discharge hole 113 to avoid the powder accumulating and obstructing the adjustment of the gap between the first grinding element 130 and the second grinding element 150. This allows the gap between the first grinding element 130 and the second grinding element 150 to be smaller than the diameter of a hair, so that the first grinding element 130 and the second grinding element 150 can also grind the hair into powder, achieving the effect of crushing hair, improving the smoothness of sewage discharge, and inhibiting the blockage of the sewage discharge channel.

[0065] like Figure 2As shown, in some embodiments, the crushing module 10 further includes a cutting tool 170, which is rotatably disposed within the crushing zone 115. Specifically, at least a portion of the cutting portion 173 of the cutting tool 170 is rotatably disposed within the crushing zone 115. By cutting the waste within the crushing zone 115 with the cutting tool 170, a cutting operation is added on top of grinding, thereby improving the crushing efficiency of the waste.

[0066] like Figure 2 As shown, in some embodiments, the second grinding member 150 is provided with a mounting hole 151, and the cutting tool 170 is rotatably disposed in the mounting hole 151 and at least partially located in the crushing zone 115, so that the cutting tool 170 can cut the waste in the crushing zone 115 and the cutting tool 170 can retract into the mounting hole 151.

[0067] It is understood that as the distance between the first grinding element 130 and the second grinding element 150 decreases, i.e., the grinding thickness decreases, interference will occur when the grinding thickness decreases to less than the size of the cutting tool 170 protruding from the crushing zone 115. To avoid the aforementioned interference problem, in this embodiment, the cutting tool 170 is configured to retract into the mounting hole 151 to prevent the cutting tool 170 from blocking the reduction of the grinding thickness to less than the diameter of a hair.

[0068] like Figure 2 As shown, in some embodiments, the cutting tool 170 includes a cutter head 171 and a cutting portion 173. The cutter head 171 is rotatably disposed within a mounting hole 151 and is configured to retract into the mounting hole 151. The cutting portion 173 is fixedly connected to the cutter head 171, and at least a portion of the cutting portion 173 is located within a shredding zone 115 to cut debris within the shredding zone 115. Preferably, the cutting portion 173 is a milling cutter. Of course, in other embodiments, the cutting portion 173 can also be a cutting blade or other existing cutting tools.

[0069] like Figures 2 to 4 As shown, in some embodiments, the discharge hole 113 includes an indirect discharge hole 1131, and the second grinding element 150 is provided with a connecting hole 152. The grinding zone 115, the mounting hole 151, the connecting hole 152, and the indirect discharge hole 1131 are sequentially connected. When the cutting tool 170 rotates, it scrapes the pulverized material in the mounting hole 151 into the connecting hole 152. In this embodiment, the cutting tool 170, in addition to cutting the waste, also assists in discharging the pulverized material. The pulverized material enters the mounting hole 151, and when the cutting tool 170 rotates, it scrapes the waste in the mounting hole 141 into the connecting hole 152, allowing the waste to be discharged to the outside through the connecting hole 152 and the indirect discharge hole 1131. It can be understood that the discharge of pulverized material can be achieved by negative pressure or by flushing water towards the mounting hole 151.

[0070] like Figure 2 and Figure 4 As shown, preferably, the outer peripheral side of the second grinding part 150 is provided with a connecting hole 152.

[0071] like Figure 3 As shown, in some embodiments, there are multiple indirect drainage holes 1131, which are spaced apart along the circumference of the crushing chamber 110. Preferably, the multiple indirect drainage holes 1131 are evenly arranged along the circumference of the crushing chamber 110.

[0072] like Figure 2 As shown, the crushing module 10 further includes a collecting ring 260, which is sleeved on the outer periphery of the crushing chamber 110. The inner side of the collecting ring 260 is provided with a collecting groove 261, which communicates with each indirect discharge hole 1131. For example... Figure 1 As shown, the collecting ring 260 is further provided with an external discharge hole 262, which is connected to the collecting groove 261.

[0073] In this embodiment, since multiple inter-spacing discharge holes 1131 are arranged circumferentially along the grinding chamber 110, the connecting hole 152 can discharge the pulverized material multiple times with each rotation of the second grinding element 150, thus improving the powder discharge efficiency. The pulverized material from the multiple inter-spacing discharge holes 1131 is collected in the collecting groove 261 by the collecting ring 260 and discharged to the outside through the external discharge hole 262, thus centrally processing the pulverized material and improving the convenience and efficiency of pulverized material processing.

[0074] In some embodiments, the collecting groove 261 is also connected to the direct discharge hole 1312, so that the pulverized material discharged from the direct discharge hole 1312 can also be discharged through the external discharge hole 262, which improves the integration of powder processing and further improves the convenience and efficiency of powder processing.

[0075] like Figure 4 As shown, in some embodiments, the cutting tool 170 is rotatably connected to the second grinding member 150, causing the cutting tool 170 to rotate; the second grinding member 150 is rotatably disposed within the mounting cavity 111, causing the cutting tool 170 to also revolve around the rotation center of the second grinding member 150. In this embodiment, since the cutting tool 170 is rotatably disposed on the second grinding member 150, and the second grinding member 150 is rotatably disposed within the mounting cavity 111, the cutting tool 170 can revolve around the rotation center of the second grinding member 150. This allows the cutting tool 170 to not only rotate on its own axis but also revolve around the center, thus enabling the cutting tool 170 to cut waste not only through rotation but also through revolve. By combining these two actions, the cutting efficiency is improved, thereby increasing the crushing efficiency.

[0076] like Figure 4As shown, in some embodiments, the rotational speed of the cutting tool 170 is greater than or less than the rotational speed of the second grinding element 150, that is, there is a rotational speed difference between the cutting tool 170 and the second grinding element 150. Therefore, during the cutting process of the cutting tool 170, the second grinding element 150 hinders the movement of the waste along the rotational direction of the cutting tool 170, reduces the force-removing effect of the waste movement, that is, increases the speed difference between the waste and the cutting tool 170, making it easier for the cutting tool 170 to cut the waste, thereby improving the cutting effect and the crushing effect.

[0077] like Figure 5 and Figure 6 As shown, in some embodiments, the crushing module 10 further includes a rotation drive device 210 and a transmission device 230. The rotation drive device 210 and the transmission device 230 are located outside the crushing zone 115. The transmission device 230 is connected to the power output end of the rotation drive device 210. The transmission device 230 drives the cutting tool 170 to rotate relative to the second grinding element 150, and also drives the second grinding element 150 to rotate. In this embodiment, the rotation drive device 210 is a conventional output torque drive device.

[0078] like Figure 6 As shown, in some embodiments, the transmission device 230 includes a sun gear 231, a planetary gear 233, and an internal gear ring 235. The sun gear 231 is fixedly connected to the power output shaft of the rotation drive device 210. The planetary gear 233 meshes with the sun gear 231 and is also coaxially and fixedly connected to the cutting tool 170. The internal gear ring 235 is fixedly connected to the grinding chamber 110 and meshes with the planetary gear 233. Since the cutting tool 170 is rotatably mounted on the second grinding element 150, the second grinding element 150 acts as a planet carrier, and the planetary gear 233 drives the second grinding element 150 to rotate during its revolution. The revolution speed of the planetary gear 233 is greater than or less than its rotational speed, i.e., the revolution speed of the planetary gear 233 is not equal to its rotational speed. Preferably, the cutting tool 170 rotates within the mounting hole 151.

[0079] In this embodiment, since the planetary gear 233 is fixedly connected to the cutting tool 170, the rotational speed of the planetary gear 233 is equal to the rotational speed of the cutting tool 170. Since the second grinding piece 150 is equivalent to a planet carrier, the revolution speed of the planetary gear 233 is equal to the rotational speed of the second grinding piece 150. Since the rotational speed of the planetary gear 233 is not equal to the revolution speed of the planetary gear 233, the rotational speed of the cutting tool 170 is not equal to the rotational speed of the second grinding piece 150, that is, there is a speed difference between the cutting tool 170 and the second grinding piece 150.

[0080] It should be noted that the revolution speed of planetary gear 233 is greater or less than its rotation speed, which is a conventional technique that can be achieved by relying on the tooth ratio.

[0081] In some embodiments, the pulverizing module 10 includes a revolution drive (not shown) for driving the second grinding element 150 to rotate. The pulverizing module 10 also includes a rotation drive (not shown) for driving the cutting tool 170 to rotate within the mounting hole 151. In this embodiment, the rotational speeds of the revolution drive and the rotation drive are adjusted to create a difference in rotational speed between the second grinding element 150 and the cutting tool 170. Both the revolution drive and the rotation drive are conventional torque-output drive devices.

[0082] like Figure 6 As shown, in some embodiments, the pulverizing module 10 further includes a retractable elastic element 190, which is located within the mounting hole 151 and abuts against both the second grinding element 150 and the cutting tool 170, allowing the cutting tool 170 to retract into the mounting hole 151. In this embodiment, when the second grinding element 150 directly abuts against the cutting tool 170, as the second grinding element 150 continues to approach the first grinding element 130, it pushes the cutting tool 170 into the mounting hole 151. The cutting tool 170 moves synchronously with the second grinding element 150, compressing the retractable elastic element 190 and preventing the cutting tool 170 from affecting the grinding thickness adjustment. After grinding is completed, the second grinding element 150 moves away from the first grinding element 130, and simultaneously, the retractable elastic element 190 elastically recovers to push the cutting tool 170 back to the pulverizing zone 115.

[0083] It is understood that the retraction elastic element 190 can be a spring, an air cushion, a rubber component, or other existing elastic structure.

[0084] In some embodiments, the crushing module 10 further includes a retraction drive device (not shown), which is offset from the crushing zone 115. The power output end of the retraction drive device is connected to the cutting tool 170, and the retraction drive device is used to drive the cutting tool 170 to retract into the mounting hole 151. In this embodiment, the retraction drive device is a conventional linear drive device, and its details are not described in this disclosure.

[0085] like Figure 4As shown, in some embodiments, the rotation center of the second grinding element 150 passes through the cutting range of the cutting tool 170, such that the cutting range of the cutting tool 170 covers the rotation center of the second grinding element 150. This ensures that after one revolution of the cutting tool 170, its cutting range covers the center of the second grinding element 150, avoiding any dead angles at the center and improving the crushing effect. Furthermore, since it is only necessary for the rotation center of the second grinding element 150 to pass through the cutting range of the cutting tool 170, without requiring the rotation center of the second grinding element 150 to pass through any specific position on the cutting tool 170, the machining and installation accuracy requirements for the second grinding element 150 and the cutting tool 170 are reduced, thereby lowering the cost of the crushing module 10.

[0086] like Figure 4 As shown, in some embodiments, the cutting range of the cutting tool 170 covers the outer circumference of the second grinding member 150, so that the cutting tool 170 can cover the periphery of the second grinding member 150, avoiding the existence of cutting dead angles at the periphery of the second grinding member 150 and improving the crushing effect.

[0087] In some embodiments, the cutting range of the cutting tool 170 is tangent to the outer circumference of the second grinding member 150. In other embodiments, the cutting range of the cutting tool 170 protrudes beyond the outer circumference of the second grinding member 150.

[0088] like Figure 4 As shown, in some embodiments, there are multiple cutting tools 170. The rotation center of the second grinding element 150 passes through the cutting range of one of the cutting tools 170, so that after each revolution of the cutting tool 170, the cutting range can cover the center of the second grinding element 150, avoiding cutting dead angles at the center of the second grinding element 150 and improving the crushing effect. Furthermore, the machining accuracy requirements and installation accuracy requirements of the second grinding element 150 and the cutting tool 170 can be reduced, thereby reducing the cost of the crushing module 10. In addition, multiple cutting tools 170 can improve cutting efficiency, thereby improving crushing efficiency.

[0089] like Figure 4 As shown, in some embodiments, there are multiple cutting tools 170, and the cutting range of at least one cutting tool 170 covers the outer circumference of the second grinding member 150, so that the cutting tool 170 can cover the periphery of the second grinding member 150, avoiding cutting dead angles at the periphery of the second grinding member 150 and improving the crushing effect. In addition, multiple cutting tools 170 can improve cutting efficiency, thereby improving crushing efficiency.

[0090] like Figure 2As shown, in some embodiments, the mounting cavity 111 is cylindrical, and the first grinding member 130 and the second grinding member 150 are respectively sleeved on the inner wall of the mounting cavity 111, that is, the outer peripheral walls of the first grinding member 130 and the second grinding member 150 are in contact with the inner wall of the mounting cavity 111, and the first grinding member 130 and the second grinding member 150 are arranged opposite each other and have the same diameter.

[0091] In this embodiment, when the rotation center of the second grinding element 150 passes through the cutting range of the cutting tool 170, after the cutting tool 170 rotates one revolution, the cutting range can cover the center of the crushing area 115, avoiding cutting dead corners at the center of the crushing area 115 and improving the crushing effect. When the cutting range of the cutting tool 170 covers the outer circumference of the second grinding element 150, the cutting tool 170 can cover the periphery of the crushing area 115, avoiding cutting dead corners at the periphery of the second grinding element 150 and improving the crushing effect.

[0092] like Figure 3 and Figure 4 As shown, in some embodiments, the discharge hole 113 includes an indirect discharge hole 1131, and the first grinding element 130 and / or the second grinding element 150 are provided with a connecting hole 152, that is, at least one of the first grinding element 130 and the second grinding element 150 is provided with a connecting hole 152. The crushing zone 115, the connecting hole 152 and the indirect discharge hole 1131 are connected in sequence, and the crushed material can be discharged to the outside in sequence through the connecting hole 152 and the indirect discharge hole 1131.

[0093] like Figure 3 As shown, in some embodiments, the discharge hole 113 includes a direct discharge hole 1132, which is connected to the bottom of the grinding zone 115 and is located on the outer periphery of the grinding zone 115. This allows the centrifugal force generated by grinding and cutting to throw the powder into the direct discharge hole 1132, thereby allowing the powder to be discharged to the outside from the direct discharge hole 1132 under the action of centrifugal force.

[0094] In some embodiments, in order to achieve a powder discharge rate greater than or equal to the powder settling rate, the direct discharge hole 1132 is flushed with high-pressure water after each period of pulverization.

[0095] In some embodiments, in order to achieve a powder discharge rate greater than or equal to the powder settling rate, after each period of pulverization, the powder is directly discharged through the negative pressure suction hole 1132.

[0096] like Figure 3 As shown, in some embodiments, there are multiple direct discharge holes 1132, and multiple direct discharge holes 1132 are arranged in an array to improve the efficiency of powder discharge.

[0097] like Figure 3As shown, in some embodiments, the shredding module 10 further includes a sealing device 180 for sealing the direct discharge port 1132. In this embodiment, the sealing device 180 seals the direct discharge port 1132 before the waste is sucked into the shredding chamber 110 by negative pressure. After the waste is sucked in, the sealing device 180 opens the direct discharge port 1132.

[0098] like Figure 3 As shown, in some embodiments, the blocking device 180 includes a blocking drive mechanism (not shown) and multiple blocking rods 181. The blocking drive mechanism is a conventional linear drive mechanism. Each blocking rod 181 is fixedly connected to the power output end of the blocking drive mechanism. The multiple blocking rods 181 are used to be inserted into multiple direct drain holes 1132 respectively to achieve the effect of blocking multiple direct drain holes 1132. When it is necessary to block the direct drain holes 1132, the blocking drive mechanism drives the multiple blocking rods 181 to be inserted into the multiple direct drain holes 1132 one by one. When it is not necessary to block the direct drain holes 1132, the blocking drive mechanism drives each blocking rod 181 to leave the corresponding direct drain hole 1132.

[0099] like Figure 5 and Figure 7 As shown, in some embodiments, the first grinding element 130 or the second grinding element 150 includes: a base 131 disposed in the mounting cavity 111, an elastic buffer 133, a movable grinding disc 135, and a locator (not shown), wherein the movable grinding disc 135 is used to grind waste. Specifically, one of the first grinding element 130 and the second grinding element 150 includes the base 131, the elastic buffer 133, the movable grinding disc 135, and the locator disposed in the mounting cavity 111. The base 131, the elastic buffer 133, the movable grinding disc 135, and the locator are movable in the axial direction of the grinding chamber 110. The other includes a fixed grinding disc 150a, which is fixedly disposed in the axial direction of the grinding chamber 110. The fixed grinding disc 150a and the movable grinding disc 135 are rotatable relative to each other, so that the movable grinding disc 135 and the fixed grinding disc 150a grind the waste together. The distance between the fixed grinding disc 150a and the movable grinding disc 135 is adjustable, so that the fixed grinding disc 150a and the movable grinding disc 135 can be adapted to the volume of the waste.

[0100] Furthermore, the elastic buffer 133 is connected to both the base 131 and the movable grinding disc 135, allowing the movable grinding disc 135 to be elastically connected to the base 131 via the elastic buffer 133. The base 131 can then move the movable grinding disc 135 via the elastic buffer 133. A positioner is located between the base 131 and the movable grinding disc 135, and is mounted on the base 131, allowing the positioner to move with the base 131. The movable grinding disc 135 is used to trigger the positioner.

[0101] It is understandable that when the pressure on the movable grinding disc 135 and the fixed grinding disc 150a is too high, the debris in the crushing zone 115 will become too dense, resulting in excessive resistance when the movable grinding disc 135 and the fixed grinding disc 150a rotate relative to each other. The cutting tool 170 also experiences significant resistance during cutting, leading to poor grinding and cutting effects, and making the cutting tool 170 more prone to breakage. Conversely, insufficient pressure results in excessive voids in the crushing zone 115, causing debris to splatter, similarly resulting in poor grinding and cutting effects. Therefore, to improve the crushing effect, the pressure needs to be maintained at a preset level.

[0102] like Figure 5 As shown, in this embodiment, in the initial state, the base 131 moves close to the fixed grinding disc 150a. The base 131 drives the movable grinding disc 135 to move through the elastic buffer 133, so as to reduce the distance between the movable grinding disc 135 and the fixed grinding disc 150a. At this time, the movable grinding disc 135 does not trigger the positioner. As the distance between the two decreases, the garbage in the crushing zone 115 gradually becomes denser. The moving speed of the base 131 is greater than the moving speed of the movable grinding disc 135, so that the distance between the base 131 and the movable grinding disc 135 gradually decreases. Simultaneously, the compression of the elastic buffer 133 gradually increases, and the pressure on the movable grinding disc 135 also gradually increases.

[0103] Since the positioner is installed on the base 131, the distance between it and the movable grinding disc 135 gradually decreases, causing the movable grinding disc 135 to gradually approach the trigger position and finally reach the trigger position and trigger the positioner. When the positioner is triggered by the movable grinding disc 135, the elastic force of the elastic buffer 133 acting on the movable grinding disc 135 increases to the preset elastic force, and the pressure (i.e., grinding pressure) on the movable grinding disc 135 just reaches the preset pressure, for example, the pressure of 10 kg. At this time, the base 131 stops moving.

[0104] When the base 131 stops approaching the fixed grinding disc 150a, as the movable grinding disc 135 continues to rotate relative to the fixed grinding disc 150a, the waste is further crushed and refined, and the volume of the waste gradually decreases. As the volume of the waste decreases, the elastic buffer 133 gradually extends and pushes the movable grinding disc 135 closer to the fixed grinding disc 150a. The elastic force of the elastic buffer 133 gradually decreases. When the volume of the waste decreases by a certain amount, the movable grinding disc 135 completely leaves the trigger position, the positioner switches to the disconnected state, and the pressure on the movable grinding disc 135 is less than the preset pressure.

[0105] When the positioner switches to the off state, the base 131 moves closer to the fixed grinding disc 150a again. The moving speed of the base 131 is greater than the moving speed of the movable grinding disc 135. Simultaneously, the compression of the elastic buffer 133 gradually increases, the pressure on the movable grinding disc 135 gradually increases, and the distance between the positioner and the movable grinding disc 135 gradually decreases.

[0106] The above process is repeated until the pulverization operation is completed.

[0107] It should be emphasized that when the locator is in the triggered state, the base 131 stops moving, the crushing operation continues, and the volume of waste continues to decrease. However, this will not immediately cause the movable grinding disc 135 to completely disengage from the triggered position. The locator can remain in the triggered state for a period of time until the volume of waste decreases to a certain extent, at which point the movable grinding disc 135 can completely disengage from the triggered position, allowing the locator to switch to the disconnected state.

[0108] In this embodiment, the preset pressure can be a specific value or a range of values. The on / off state of the positioner determines whether the pressure on the movable grinding disc 135 has reached the preset pressure. When the movable grinding disc 135 triggers the positioner, the pressure on the movable grinding disc 135 is equal to the preset pressure; when the movable grinding disc 135 does not trigger the positioner, the pressure on the movable grinding disc 135 is less than the preset pressure. Whenever the pressure on the movable grinding disc 135 is less than the preset pressure, the base 131 moves closer to the fixed grinding disc 150a, increasing the compression of the elastic buffer 133, thereby increasing the pressure on the movable grinding disc 135 to the preset pressure; whenever the pressure on the movable grinding disc 135 equals the preset pressure, the base 131 stops, maintaining the pressure on the movable grinding disc 135 at the preset pressure. Thus, through the coordinated operation of the base 131, the elastic buffer 133, the positioner, and the movable grinding disc 135, the movable grinding disc 135 is ensured to work under the preset pressure, that is, the grinding pressure is ensured to be maintained at the preset pressure, which improves the grinding efficiency and cutting efficiency, thereby improving the crushing efficiency. At the same time, it suppresses the risk of the cutting tool 170 breaking and improves the service life of the cutting tool 170.

[0109] like Figure 5 and Figure 7 As shown, in some embodiments, the first grinding element 130 includes a base 131 disposed within the mounting cavity 111, an elastic buffer 133, a movable grinding disc 135, and a positioner. The second grinding element 150 includes a fixed grinding disc 150a, the movable grinding disc 135 is movable in the axial direction of the grinding chamber 110, and the fixed grinding disc 150a is immovable in the axial direction of the grinding chamber 110. In this embodiment, the base 131, through the elastic buffer 133, moves the movable grinding disc 135 closer to the fixed grinding disc 150a, thereby reducing the distance between the first grinding element 130 and the second grinding element 150 solely through the movement of the movable grinding disc 135.

[0110] It is understood that the elastic buffer 133 can be a spring, an air cushion, a rubber component, or other existing elastic structures. The positioner can also be a photoelectric sensor, a contact sensor, or other existing components for triggering positioning; for example, in some embodiments, the positioner is a linear sliding positioner.

[0111] like Figure 5 As shown, in some embodiments, the crushing module 10 further includes a distance adjustment device 250. The base 131 is connected to the power output end of the distance adjustment device 250. The distance adjustment device 250 is used to drive the base 131 to move in order to adjust the distance between the base 131 and the fixed grinding disc 150a, and to adjust the distance between the movable grinding disc 135 and the fixed grinding disc 150a.

[0112] like Figure 7 As shown, in some embodiments, the adjusting device 250 includes an output gear (not shown), a threaded sleeve 251, and a screw 252. The output gear is rotatably disposed outside the crushing chamber 110, and the threaded sleeve 251 is rotatably disposed outside the crushing chamber 110. A driven gear 2511 is fixedly disposed on the outer periphery of the threaded sleeve 251, and the driven gear 2511 meshes with the output gear. The screw 252 passes through the threaded sleeve 251 and is threadedly connected to the threaded sleeve 251. A limiting block protrudes from the inner side of the threaded sleeve 251, and a limiting groove is recessed along the axial direction of the screw 252 on the outer side of the screw 252. The limiting block slides within the limiting groove. Through the cooperation of the limiting block and the limiting groove, the rotation of the screw 252 is prevented, and the rotation of the threaded sleeve 251 is converted into the axial movement of the screw 252. In this embodiment, the output gear drives the screw sleeve 251 to rotate, and the screw sleeve 251 drives the screw 252 to move axially. By adjusting the rotation direction of the screw sleeve 251, the movement direction of the screw 252 can be adjusted. Furthermore, the torque adjustment device 250 also includes a power adjustment mechanism, which is a device for adjusting the output torque of a conventional power mechanism.

[0113] Of course, in other embodiments, the pitch adjustment device 250 may also be a cylinder or other existing linear drive device.

[0114] like Figure 2 and Figure 3 As shown, in some embodiments, the pulverizing module 10 includes a pulverizing chamber 110, a first grinding element 130, a second grinding element 150, and a cutting tool 170. The pulverizing chamber 110 is provided with a mounting cavity 111 and a direct discharge hole 1132, which communicates with the mounting cavity 111. The aperture of the direct discharge hole 1132 is such that only powder can pass through, and the aperture size that allows only powder to pass through is a conventional technology.

[0115] A first grinding element 130 and a second grinding element 150 are disposed within the mounting cavity 111. The second grinding element 150 and the first grinding element 130 are arranged opposite to each other and can rotate relative to each other. A pulverizing zone 115 is formed between the second grinding element 150 and the first grinding element 130. The pulverizing zone 115 is used to hold waste, and the first grinding element 130 and the second grinding element 150 grind the waste together. The bottom of the pulverizing zone 115 is connected to a direct discharge hole 1132, and the direct discharge hole 1132 is located on the outer periphery of the pulverizing zone 115. The distance between the second grinding element 150 and the first grinding element 130 is adjustable, that is, the grinding thickness between the second grinding element 150 and the first grinding element 130 is adjustable, so that the space in the pulverizing zone 115 can be adjusted according to the volume of waste, thereby keeping the grinding pressure of the first grinding element 130 and the second grinding element 150 at a preset grinding pressure.

[0116] The second grinding element 150 has a mounting hole 151, and a cutting tool 170 is rotatably disposed within the mounting hole 151. At least a portion of the cutting tool 170 is located within the pulverizing zone 115 to cut debris within the pulverizing zone 115. The distance between the second grinding element 150 and the first grinding element 130 is adjustable, ensuring that the cutting pressure of the cutting tool 170 is maintained at a preset cutting pressure. The cutting tool 170 is configured to retract into the mounting hole 151. As the distance between the first grinding element 130 and the second grinding element 150 decreases, i.e., the grinding thickness decreases, interference will occur when the grinding thickness decreases to less than the size of the cutting tool 170 protruding from the pulverizing zone 115. To avoid this interference problem, the cutting tool 170 is configured to retract into the mounting hole 151 to prevent the cutting tool 170 from obstructing the reduction of the grinding thickness to less than the diameter of a hair.

[0117] In this embodiment, the working principle of the crushing module 10 is as follows:

[0118] 1. Preparation stage: The distance between the first grinding part 130 and the second grinding part 150 is at its maximum value, and the first grinding part 130, the second grinding part 150 and the cutting tool 170 are all stationary.

[0119] 2. Feeding stage: Waste enters the crushing zone 115 formed between the first grinding element 130 and the second grinding element 150 through the feeding hole. The waste can be sucked into the mounting cavity 111 by negative pressure, or it can be manually poured into the crushing zone 115. When feeding by negative pressure, the direct discharge hole 1132 is closed.

[0120] 3. Crushing Stage: The feed hole is closed, while the discharge hole 1132 is either open or intermittently open. The first grinding element 130 and the second grinding element 150 rotate relative to each other to grind the waste in the crushing zone 115, and the cutting tool 170 rotates to cut the waste. The waste gradually becomes finer after grinding and cutting, reducing its volume. Therefore, during the grinding and cutting process, the distance between the first grinding element 130 and the second grinding element 150 is gradually reduced to maintain the grinding pressure and cutting pressure at the preset levels, thereby improving grinding efficiency and cutting effect. It is understood that the preset pressure cannot be set too high to avoid the cutting tool 170 easily breaking due to excessive pressure.

[0121] In this process, the waste is gradually pulverized, generating powder within the pulverizing zone 115. Although the powder particles are small, their density is greater than air and more compact than large, porous pieces of waste. Under the influence of gravity, they sink along the gaps in the larger pieces of waste and eventually accumulate at the bottom of the pulverizing zone 115. The relative rotation of the first grinding element 130 and the second grinding element 150, as well as the relative rotation of the cutting tool 170, generates centrifugal force. Since the direct discharge hole 1132 is connected to the bottom of the pulverizing zone 115 and is located on the outer periphery of the pulverizing zone 115, the powder at the bottom of the pulverizing zone 115 can pass through the direct discharge hole 1132 under centrifugal force. 2. Discharge allows for simultaneous pulverization and powder discharge, with the discharge speed being greater than or equal to the powder settling speed, preventing the deposited powder layer from hindering the adjustment of the grinding thickness. Furthermore, as the distance between the first grinding element 130 and the second grinding element 150 decreases, the distance between them will be less than the size of the cutting tool 170 protruding from the pulverization area 115. Since the cutting tool 170 can retract into the mounting hole 151, it avoids hindering the adjustment of the grinding thickness. Therefore, neither the settled powder layer nor the cutting tool 170 will hinder the adjustment of the grinding thickness, ensuring that the grinding thickness can be adjusted to a value smaller than the diameter of a hair, allowing the hair to be pulverized.

[0122] It is understandable that the space of the crushing zone 115 gradually decreases as the volume of waste decreases, making the space within the crushing zone 115 relatively compact. Therefore, the violent stirring and airflow impact during the crushing process are insufficient to lift the powder or the amount lifted is small, and will not affect the discharge of powder by centrifugal force.

[0123] 4. Reset stage: When the distance between the first grinding element 130 and the second grinding element 150 can no longer be reduced, the waste has been fully crushed. The first grinding element 130, the second grinding element 150 and the cutting tool 170 all stop. The distance between the first grinding element 130 and the second grinding element 150 is reset to the maximum value. The cutting tool 170 is reset to the state of protruding from the crushing zone 115.

[0124] The aforementioned shredding module 10 not only cuts the waste with the cutting tool 170, but also grinds the waste together with the first grinding element 130 and the second grinding element 150, so that the waste undergoes both cutting and grinding. Since the distance between the first grinding element 130 and the second grinding element 150 is adjustable, that is, the grinding thickness is adjustable, the grinding pressure is maintained at a preset grinding pressure, and the cutting pressure is maintained at a preset cutting pressure. In this way, the waste is not only ground with a preset grinding pressure, but also cut with a preset cutting pressure, which improves the efficiency of waste shredding.

[0125] Because the cutting pressure can be maintained at the preset cutting pressure, excessive pressure on the cutting tool 170 is avoided, the cutting tool 170 is prevented from breaking, and the service life of the cutting tool 170 is extended.

[0126] During the grinding and cutting process, the waste is gradually pulverized, generating powder within the pulverizing zone 115. Although the powder particles are small, their density is greater than air and more compact than large, porous pieces of waste. Under the influence of gravity, they sink along the gaps in the larger pieces of waste and eventually accumulate at the bottom of the pulverizing zone 115. The relative rotation of the first grinding element 130 and the second grinding element 150, as well as the relative rotation of the cutting tool 170, generates centrifugal force. Since the direct discharge hole 1132 is connected to the bottom of the pulverizing zone 115 and is located on the outer periphery of the pulverizing zone 115, under centrifugal force, the powder... The powder at the bottom of the crushing zone 115 can be discharged through the direct discharge hole 1132, allowing crushing and powder discharge to proceed simultaneously. The powder discharge speed can be greater than or equal to the powder settling speed, preventing the deposited powder layer from hindering the adjustment of the grinding thickness. In addition, since the cutting tool 170 can retract into the mounting hole 151, the cutting tool 170 is prevented from hindering the adjustment of the grinding thickness. Thus, neither the settled powder layer nor the cutting tool 170 will hinder the adjustment of the grinding thickness, ensuring that the grinding thickness can be adjusted to a value smaller than the diameter of a hair, so that the hair can be crushed, improving the smoothness of the sewage discharge and inhibiting the blockage of the sewage discharge channel.

[0127] This disclosure also provides a processing base station, including a housing and a shredding module of any of the above embodiments. The housing is provided with a mounting cavity and a return area. The shredding module is installed in the mounting cavity, and the return area is used to dock cleaning equipment. It is understood that the cleaning equipment can be a sweeping robot, a mopping robot, a floor washing robot, a sweeping and mopping robot, or other existing cleaning robots.

[0128] like Figure 8 As shown, this disclosure also provides a pulverizing method, which uses the pulverizing module of any of the above embodiments for pulverizing. The pulverizing method includes:

[0129] S101, Control the relative rotation of the first grinding piece and the second grinding piece.

[0130] In this embodiment, the first grinding element and the second grinding element are controlled to rotate relative to each other, so that the first grinding element and the second grinding element grind the waste together. To achieve grinding, the first grinding element can be stationary while the second grinding element rotates; the first grinding element can rotate while the second grinding element is stationary; both the first and second grinding elements can rotate, but in opposite directions; or both the first and second grinding elements can rotate in the same direction, but at different speeds.

[0131] S103. Control the distance between the first grinding element and the second grinding element to decrease, and obtain the grinding pressure.

[0132] In this embodiment, the distance between the first and second grinding elements is reduced to adapt the distance between them to the volume of the waste. Furthermore, the grinding pressure is acquired using existing sensors to check the value of the grinding pressure.

[0133] S105. When the grinding pressure is equal to the preset pressure, control the distance between the first grinding piece and the second grinding piece to stop decreasing.

[0134] In this embodiment, the grinding pressure is the pressure exerted on both the first and second grinding elements. When the grinding pressure reaches a preset pressure, such as 10 kg, the distance between the first and second grinding elements is controlled to stop decreasing.

[0135] S107. When the grinding pressure is less than the preset pressure, return to step S103.

[0136] When the grinding pressure is less than the preset pressure, the grinding effect deteriorates. The process returns to step S103 to reduce the distance between the first grinding element and the second grinding element, thereby increasing the grinding pressure to improve the grinding effect.

[0137] In the above-described pulverizing method, during the grinding process, the distance between the first and second grinding elements is controlled to decrease, and grinding pressure is acquired. When the grinding pressure equals a preset pressure, the distance between the first and second grinding elements is stopped from decreasing. When the grinding pressure is less than the preset pressure, the distance between the first and second grinding elements is controlled to decrease again. Thus, by acquiring and adjusting the grinding pressure, the grinding pressure is maintained at the preset pressure, improving grinding efficiency and consequently, pulverizing efficiency.

[0138] In some embodiments, prior to step S101, the pulverizing method further includes adjusting the distance between the first grinding element and the second grinding element to its maximum value. In this embodiment, adjusting the distance between the first grinding element and the second grinding element to its maximum value maximizes the space of the pulverizing zone, thereby allowing the pulverizing zone to accommodate more waste.

[0139] In some embodiments, in step S107, when the duration of the grinding pressure equal to the preset pressure is greater than the preset duration, the first grinding element and the second grinding element are controlled to stop rotating relative to each other, and the distance between the first grinding element and the second grinding element is adjusted to the initial distance.

[0140] In this embodiment, when the grinding pressure is equal to the preset pressure for a duration longer than the preset duration, it means that the waste cannot be further crushed, that is, the crushing operation has been completed. At this time, the crushing module is reset, that is, the first grinding piece and the second grinding piece are stopped from rotating relative to each other, and the distance between the first grinding piece and the second grinding piece is adjusted to the initial distance, so that the crushing module ends the crushing work in time, reducing the idling time and improving the crushing efficiency.

[0141] In some embodiments, after step S103, the pulverizing method further includes: S104, obtaining the reduction value of the distance between the first grinding element and the second grinding element in real time, and when the reduction amount of the distance is equal to the preset reduction value, controlling the first grinding element and the second grinding element to stop rotating relative to each other, and adjusting the distance between the first grinding element and the second grinding element to the initial distance.

[0142] In this embodiment, when the distance between the first grinding element and the second grinding element decreases, the distance between the first grinding element and the second grinding element is at its minimum value, that is, the first grinding element and the second grinding element are in contact, and there is no waste in the crushing zone. The first grinding element and the second grinding element are controlled to stop rotating relative to each other, and the distance between the first grinding element and the second grinding element is adjusted to the initial distance to avoid the crushing module from running idle and improve the crushing efficiency.

[0143] In some embodiments, the first grinding element includes: a base, an elastic buffer, a movable grinding disc, and a positioner, all disposed within a mounting cavity. The elastic buffer is connected to both the base and the movable grinding disc. The base is axially movable within the grinding chamber, allowing it to drive the movable grinding disc via the elastic buffer. The positioner is mounted on the base. The second grinding element includes a fixed grinding disc, which is immovable along the axial direction of the grinding chamber (i.e., the fixed grinding disc is fixed axially within the grinding chamber). The movable grinding disc is positioned opposite the fixed grinding disc, forming a grinding zone between them. Rotation of at least one of the movable and / or fixed grinding discs allows relative rotation between the movable and fixed grinding discs. Driven by the base, the movable grinding disc can move axially and approach the fixed grinding disc, making the distance between them adjustable. Specifically, the base, through the elastic buffer, drives the movable grinding disc closer to the fixed grinding disc, reducing the distance between the first and second grinding elements solely through the movement of the movable grinding disc.

[0144] Further, step S103 specifically involves: reducing the distance between the base and the movable grinding disc, thereby reducing the distance between the movable grinding disc and the fixed grinding disc; and determining whether the grinding pressure has reached the preset pressure through the positioner.

[0145] In this embodiment, initially, the base moves closer to the fixed grinding disc, and the base, through an elastic buffer, drives the movable grinding disc to move, reducing the distance between the movable and fixed grinding discs. At this time, the movable grinding disc does not trigger the positioner. As the distance between them decreases, the waste in the crushing zone gradually compacts, and the base's moving speed exceeds that of the movable grinding disc, causing the distance between the base and the movable grinding disc to gradually decrease. Simultaneously, the compression of the elastic buffer gradually increases, and the pressure on the movable grinding disc also gradually increases. Since the positioner is installed on the base, its distance from the movable grinding disc also gradually decreases, causing the movable grinding disc to enter the trigger position and trigger the positioner. When the positioner is triggered, it can be determined that the grinding pressure has reached the preset pressure.

[0146] Furthermore, step S105 specifically involves: when the movable grinding disc triggers the positioner, the distance between the control base and the movable grinding disc stops decreasing.

[0147] In this embodiment, when the movable grinding disc triggers the positioner, the compression of the elastic buffer reaches a preset length, and the grinding pressure reaches a preset pressure, such as 10 kg. At this point, the distance between the control base and the movable grinding disc stops decreasing. As the distance between the base and the movable grinding disc stops decreasing, the waste is further refined as the movable grinding disc and the fixed grinding disc continue to rotate relative to each other, and the volume of the waste gradually decreases. As the volume of the waste decreases, the elastic buffer gradually extends and pushes the movable grinding disc away from the positioner. The elastic force of the elastic buffer gradually decreases. When the volume of the waste decreases by a certain amount, the movable grinding disc completely leaves the trigger position, the positioner switches to the disconnected state, and the pressure on the movable grinding disc is less than the preset pressure.

[0148] Furthermore, step S107 specifically involves returning to step S103 when the locator switches to the disconnected state.

[0149] In this embodiment, when the positioner switches to the disconnected position, the compression and elasticity of the elastic buffer decrease, and the grinding pressure is less than the preset pressure. At this time, the process returns to step S103, and the distance between the control base and the movable grinding disc continues to decrease.

[0150] In the pulverizing method of the previous embodiment, the on / off state of the positioner determines whether the grinding pressure has reached the preset pressure. When the movable grinding disc triggers the positioner, the grinding pressure equals the preset pressure; when the movable grinding disc does not trigger the positioner, the grinding pressure is less than the preset pressure. Whenever the grinding pressure is less than the preset pressure, the base moves closer to the fixed grinding disc, increasing the compression of the elastic buffer, thereby increasing the grinding pressure to the preset pressure, and decreasing the distance between the movable and fixed grinding discs; whenever the grinding pressure equals the preset pressure, the base stops, maintaining the grinding pressure at the preset pressure. Thus, through the coordinated operation of the base, elastic buffer, positioner, and movable grinding disc, the grinding pressure is maintained at the preset pressure, improving grinding and cutting efficiency, thereby increasing pulverizing efficiency, while simultaneously suppressing the risk of cutting tool breakage and extending the service life of the cutting tools.

[0151] Compared with the prior art, this disclosure has at least the following advantages:

[0152] The aforementioned pulverizing module contains waste in the pulverizing zone, and the waste can be pulverized during the relative rotation of the first and second grinding parts. The distance between the first and second grinding parts is adjustable. During the pulverizing process, the distance between the first and second grinding parts gradually decreases, so that the distance between them is adapted to the volume of the waste, thereby maintaining the pulverizing pressure at the preset pressure and improving the pulverizing efficiency.

[0153] Since the garbage usually contains hard objects such as wood chips, gravel, and stones, during the relative rotation of the first and second grinding parts, the hard objects in the garbage will move with the grinding force, so that the hard objects have a grinding effect on the hair, and then the hard objects grind the hair into powder, which can achieve the effect of crushing the hair, improving the smoothness of sewage discharge and inhibiting the blockage of sewage channels.

[0154] Since the discharge hole is connected to the grinding zone, the powder generated during the grinding process can be discharged through the discharge hole to avoid the powder from accumulating and hindering the adjustment of the distance between the first grinding piece and the second grinding piece. This allows the distance between the first grinding piece and the second grinding piece to be smaller than the diameter of a hair, so that the first grinding piece and the second grinding piece can also grind the hair into powder, achieving the effect of crushing the hair, improving the smoothness of sewage discharge, and inhibiting the blockage of the sewage discharge channel.

[0155] In the above-described pulverizing method, during the grinding process, the distance between the first and second grinding elements is controlled to decrease, and grinding pressure is acquired. When the grinding pressure equals a preset pressure, the distance between the first and second grinding elements is stopped from decreasing. When the grinding pressure is less than the preset pressure, the distance between the first and second grinding elements is controlled to decrease again. Thus, by acquiring and adjusting the grinding pressure, the grinding pressure is maintained at the preset pressure, improving grinding efficiency and consequently, pulverizing efficiency.

[0156] It should be noted that, without causing logical conflicts or technical contradictions, the various embodiments of this disclosure can be combined with each other to form new embodiments; and, each embodiment, including new embodiments and original embodiments, can be further combined with some technical features of other embodiments.

[0157] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these are all implicitly contained within this disclosure.
