[0043] Figure 10 A schematic diagram of a control system according to other embodiments of the present invention is shown. Detailed Implementation

[0044] To facilitate understanding of the present invention, several exemplary embodiments will be described below in conjunction with the accompanying drawings. It will be understood by those skilled in the art that the embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0045] According to one aspect of the invention, Figure 1A and 1B A schematic diagram of a shredding apparatus according to some embodiments of the present invention is shown. The shredding apparatus may be, for example, a shredder, device, machine, etc., for processing or handling materials. The materials may be undesirable substances present in a particular situation or location, such as garden waste, including but not limited to branches, fallen leaves, weeds, and man-made undesirable items such as waste paper, debris, etc.

[0046] As shown, the pulverizing device includes a pulverizing section 110 and a collecting section 180. The pulverizing section 110 is used to pulverize materials, and the collecting section 180 is generally disposed below and communicates with the pulverizing section 110 for receiving or containing the pulverized materials. As an example, the collecting section 180 is configured as a box or cassette type. Other suitable configurations are also possible.

[0047] The crushing unit 110 includes a housing 120. The housing 120 has an inlet 122, and a crushing mechanism (not shown) is provided in the housing 120. During operation, material enters the housing 120 through the inlet 122 and is then processed by the crushing mechanism.

[0048] Optionally, when not in use, the pulverizing part 110 can be housed in the collecting part 180. This state can be referred to as the housing state of the pulverizing device or pulverizing mechanism, while the state during normal operation of the pulverizing device can be referred to as the working state. In the housing state, most or all of the pulverizing part 110 can be accommodated in the space of the collecting part 180, which is advantageous for storage, transportation, etc. Not only does it save space, but it also protects the pulverizing part 110. For example, it can prevent or mitigate the entry or contact of undesirable substances such as water, chemicals, and atmospheres into or with the pulverizing part 110. This is beneficial for protecting the mechanical parts, electrical components, wiring, etc., and can also extend the service life of the pulverizing device.

[0049] Switching the pulverizer section 110 from its operating state to its receiving state can be achieved in various ways. As an example, a suitable positioning or locking mechanism (not shown) is provided on the top 182 of the collecting section 180. In the operating state, the positioning mechanism positions or locks the pulverizer section 110. The top 182 is also provided with an elastic member 186 (e.g., a pair of torsion springs). Figure 1A Only one is shown; the other is obscured by the housing. The elastic member 186 facilitates the positioning of the pulverizer portion 110, but at the same time allows the pulverizer portion 110 to pivot about the axis PP'. To switch the pulverizer portion 110 to the receiving state, the positioning mechanism can be operated to release the positioning, and then the pulverizer portion 110 can be folded into the collection portion 180 around PP'.

[0050] A power unit, such as an electric motor, can be housed within the housing 120 to power the crushing mechanism. A power supply cover 132 is provided on the housing 120. The power supply cover 132 can be provided independently or as part of the housing 120 to increase the compactness and streamlined design. The power supply cover 132, either alone or together with the housing 120, defines a power supply chamber. The power supply chamber can be used to house a power supply device, such as a battery pack or battery array, for providing power to the power unit. A safety key can also be provided in the power supply chamber to prevent unintended accidental activation of the power supply device.

[0051] Figure 1C Battery pack 134 is shown. Battery pack 134 can be used, for example, in... Figure 1A The pulverizing device is housed within the power supply chamber. For ease of description, the battery pack 134 is shown as a cuboid with length, width, and height L, W, and H, respectively, where L is greater than W and H. In the pulverizing device, the battery pack 134 can be configured vertically or horizontally. In a vertical configuration, the long side L of the battery pack 134 is approximately equal to... Figure 1A The y-direction shown is parallel. In a laterally configured configuration, the long side L of the battery pack 134 is approximately parallel to... Figure 1B The z-direction shown is parallel. In other words, the long side L of the battery pack 134 is approximately parallel to the pivot axis PP' of the crushing body section 110.

[0052] In some embodiments, a lateral configuration of the battery pack is advantageous. This, for example, prevents unwanted obstruction during the switching of the crushing section from its operational state to its containment state. In other words, the switching process can be completed without removing the battery pack.

[0053] Alternatively, a user interface or user interface 140 may be provided on the housing 120. Figure 1B This allows users to easily interact with the pulverizing device. For example, user interface 140 can display one or more statuses of the pulverizing device to the user, such as power level or blockage status. Furthermore, user interface 140 can allow the user to input one or more variables to manipulate the pulverizing device.

[0054] According to another aspect of the invention, Figure 2 A schematic diagram of a pulverizing mechanism according to some embodiments of the present invention is shown. The pulverizing mechanism may, for example, be... Figure 1A and 1B A specific embodiment of the crushing device shown, comprising the crushing mechanism disposed within its housing.

[0055] like Figure 2As shown, the crushing mechanism includes a crushing component 210 and an adjusting component 220. The material to be crushed rests against the adjusting component 220. The crushing component 210 performs a crushing operation, such as cutting, on the material resting against the adjusting component 220. The adjusting component 220 and the crushing component 210 define an operating space or operating gap 230 for the crushing operation. The size of this operating space 230 can be adjusted by relative movement between the adjusting component 220 and the crushing component 210. In some embodiments, at least a portion of the adjusting component 220 is movable relative to the crushing component 210, thereby changing the size of the operating space 230.

[0056] The crushing component 210 is made of a material with a certain hardness and has functions such as cutting, crushing, or tearing. The crushing component 210, for example, has an edge sized to perform one or more functions such as cutting, crushing, or tearing. In this embodiment, the crushing component 210 is illustrated as a rolling cutter configuration with six blades or edges that rotates counterclockwise in direction C during operation. Other suitable crushing component configurations are also possible.

[0057] The operating space 230 can be understood, for example, as the permissible operating space between the crushing component and the adjusting component when the material passes through the crushing mechanism. Depending on actual needs, different physical quantities can be used to characterize the operating space 230. For example, the operating space 230 can be characterized by the shortest distance D between the adjusting component 220 and the crushing component 210. The operating space 230 affects the crushing operation of the material. For example, material with a permissible size (e.g., diameter) smaller than D passes through the crushing mechanism without being processed. That is, for a smaller operating space corresponding to a smaller distance D, the size of the processed material is generally smaller in one or more dimensions. In an ideal situation, the size of the processed material in at least one direction does not exceed D.

[0058] The adjusting member 220 can move toward or away from the crushing member 210, thereby adjusting the operating space 230. In some embodiments, the crushing member 210 may also be configured to move toward or away from the adjusting member 220. The adjusting member 220 may be configured to move entirely relative to the crushing member 210, or only a portion of it may be configured to move relative to the crushing member 210. This movement may be linear, rotational, or a combination of both. For example, in some embodiments, the adjusting member includes a plate member that is operatively movable, for example, one end of the plate member may be pivotally rotatable.

[0059] Adjustment component 220 can be operated manually or electrically. Optionally, by way of example, Figure 2The drive component 240 is shown. The drive component 240 is coupled to the adjustment component 220, thereby enabling the adjustment component 220 to move relative to the crushing component 210 during operation.

[0060] When the drive adjustment component 220 is driven, the drive component 240 itself performs linear motion, rotational motion, or a combination of both. The drive component 240 can be operated manually, electrically, or both, allowing the user to choose the method as needed. For example, in some embodiments, the drive component 240 is connected to the output of a motor via a transmission system, so that the drive component 240 can be operated by means of a motor.

[0061] One or more embodiments herein recognize that, in practice, adjustments to the operating space are necessary. This may be for various reasons, such as the size of the material. Furthermore, one or more embodiments herein recognize that, with use of the crushing mechanism and / or over time, the operating space may change due to component wear, which can reduce the effectiveness of the crushing operation. Other reasons are also possible. In these cases, appropriate adjustment of the operating space is advantageous for improving the effectiveness of the crushing operation. The apparatus, mechanism, system, or method according to this embodiment and one or more embodiments below are also advantageous in this respect, among other advantages.

[0062] Figure 3A and 3B A schematic diagram of a pulverizing mechanism according to some embodiments of the present invention is shown. The pulverizing mechanism shown may be, for example, […]. Figure 2 A specific embodiment of the crushing mechanism. The crushing mechanism shown can, for example, be used in... Figure 1A and 1B In the crushing device shown.

[0063] exist Figure 3A In the middle, the crushing component 310 and the adjusting component 320 define the operating space 330A. The adjusting component 320 may be disposed in the housing of the crushing device (e.g., Figure 1A The adjustment component 320 is plate-shaped, with its first end 322 fixed to the inner wall of the crushing device housing (not shown) via a pivot P, and its second end 324 suspended and rotatable relative to the pivot P.

[0064] The drive component 340 is exemplified as a helical component, such as a bolt. The drive component 340 includes a knob 342 and a screw 344 connected to the knob 342. One end of the screw 344, away from the knob 342, is coupled to a second end 324 of the adjusting component 320 to drive movement of the second end 324 and provide support for the second end 324. The screw 344 can be connected to or disconnected from the second end 324. In some embodiments, connection is advantageous to... Figure 3A For example, this allows the second end 324 to be pivoted to the left, thus providing greater flexibility in adjusting the operating space.

[0065] The drive component 340 is coupled to the housing of the crushing device (for simplicity, Figure 3A and 3B Only a portion of the housing 360 is shown; more specifically, the screw 344 passes through a hole (not shown) in the housing 360. That is, the knob 342 is outside the housing of the crushing device, while components such as the crushing element 310 and the adjustment element 320 are located inside the housing of the crushing device, thereby allowing personnel to operate the adjustment elements from outside the crushing device to adjust the operating space without having to open the housing.

[0066] The screw 344 has threads, and the area where the housing contacts the screw 344 (i.e., the inner wall of the hole) also has threads. The threads on the inner wall of the hole match the threads on the screw 344, so that the drive component 340 can be fixed or locked when the knob 342 is not rotated. When the knob 342 is rotated, depending on the direction of rotation, the screw 344 moves in the positive or negative direction of x, thereby causing the second end 324 of the adjusting component 320 to move closer to or further away from the crushing component 310.

[0067] and Figure 3A In comparison, Figure 3B As the screw 344 rotates along the x-direction, the second end 324 contacts the tip A of one of the blades of the crushing component 310. The operating space 330B decreases relative to the operating space 330A.

[0068] In some other embodiments, the knob is not configured to rotate, but rather to be pressed (e.g. Figure 3A (along the positive x-direction) or pulling (e.g.) Figure 3A The adjustment component is driven by operating along the negative x-direction. In this case, the driving component only performs linear motion and does not rotate during operation.

[0069] Figure 4 A schematic diagram of a pulverizing mechanism according to other embodiments of the present invention is shown. Figure 4In this configuration, the crushing component 410 and the adjusting component 420 define an operating space 430. The driving component 440 is coupled to the adjusting component 420 to drive the adjusting component 420 in a direction parallel to the x-axis.

[0070] exist Figure 4 The locking component 450 is shown. The locking component 450 can switch the driving component 440 between a first state and a second state. The first state is, for example, a locked state, and the second state is, for example, an unlocked state. In the locked state, the driving component 440 is prohibited from driving the adjustment component 420, and in the unlocked state, it is allowed to drive the adjustment component 420. This prevents undesirable changes to the operating space 430 due to accidental touch.

[0071] In some embodiments, the locking member 450 is exemplified as a quick-release mechanism. A first state is, for example, a fine-tuning or micro-tuning state, and a second state is, for example, a coarse-tuning state. The locking member 450 can switch the drive member 440 between the fine-tuning and coarse-tuning states. In the fine-tuning state, the drive member 440 can adjust the operating space 430 at a slower rate. In the coarse-tuning state, the drive member 440 can adjust the operating space 430 at a faster rate. In some embodiments, the locking member 450 is coupled to the drive member 440 via a base 460. The base 460 is coupled to a portion 470 of the housing of the crushing device, and the base 460 itself may also be configured as part of the housing 470.

[0072] Locking member 450 and driving member 440 pass through corresponding holes in base 460. Driving member 440 has a first thread, and one end 452 of locking member 450 has a second thread. At the positions of the corresponding holes, both the first and second threads are exposed to the inner walls of the corresponding holes. At the bottom end 442 of driving member 440, the second thread engages with the first thread, thereby placing driving member 440 in a locked or fine-tuned state (in...). Figure 4 In the diagram, for clarity, bottom end 442 and end 452 are separated (in the locked state, they are actually engaged). To unlock or coarsely adjust the drive component 440, the locking component 450 can be moved downwards in the y-direction (e.g., pressed or pushed) to disengage the second thread from the first thread. In the unlocked state, the drive component 440 can move freely in the x-direction (e.g., linear movement, or a combination of rotation and linear movement).

[0073] Figure 5A and 5B A schematic diagram of a pulverizing apparatus according to other embodiments of the present invention is shown. The pulverizing apparatus may, for example, be... Figure 1A and 1B A specific embodiment of the pulverizing device shown.

[0074] The pulverizing device includes a pulverizing body 510 and a collecting part 580. The pulverizing body 510 has a pulverizing mechanism inside its housing 520, for example, refer to... Figures 2 to 4 The crushing mechanism exemplified by any of these embodiments. A window 560 is provided on at least a portion of the housing 520. Through the window 560, at least a portion of the operating space is visually visible from the outside of the housing 520, which may be visible over a wide angular range or at a specific angle. Thus, the internal situation can be viewed without opening the housing, which is advantageous for operation.

[0075] Optionally, as illustrated, window 560 is provided with a cover 562. Figure 5B For clarity, the cover 562 is moved outside the crushing device. The cover 562 is configured to cover or expose the window 560 by sliding (e.g., parallel sliding) or rotating (e.g., pivoting). The cover 562 prevents material from being ejected from the window 560 during operation, posing a hazard to personnel and requiring recollection. In some cases, the cover 562 may also prevent external objects from entering the housing, thereby protecting internal components or operations.

[0076] According to another aspect of the invention, Figure 6 A schematic diagram of a control system according to some embodiments of the present invention is shown. This control system can, for example, be used to control a reference... Figure 1A , 1B The crushing devices of 5A and 5B are controlled. In this description, the terms "control of the crushing device" and "control of the crushing mechanism" have some overlap in meaning, and in some cases, they express the same or essentially the same meaning.

[0077] like Figure 6 As shown, the control system includes a detection circuit 610 and a control circuit 620. The detection circuit 610 can be used to detect contact between the adjusting component and the crushing component of the crushing device. The control circuit 620 can be used to respond when the detection circuit detects contact. The response includes, for example, moving the adjusting component away from the crushing component, urgently stopping the crushing component, or de-energizing the crushing device. This control system can operate continuously when the crushing device is in operation, or it can operate selectively when the crushing device is not in operation.

[0078] Contact between the adjusting components and the crushing components is undesirable, as it can cause damage, wear, and operational hazards. This control system can better avoid or reduce undesirable contact between the two components and take timely measures when such contact occurs, thereby improving safety and benefiting the lifespan of the equipment. On the other hand, excessive operating space between the adjusting components and the crushing components is also undesirable, as it can affect the crushing effect or lead to reduced crushing efficiency. This control system can better assist in adjusting or controlling the size of the operating space, thereby continuously ensuring the efficient operation of the crushing device.

[0079] also, Figure 6 The control system shown can be mounted on one or more circuit boards of the crushing device, integrated into the crushing device's circuitry as part of the circuitry, or it can be configured as a separate circuit module that electrically communicates with other circuitry systems of the crushing device. In some embodiments, at least a portion of the control system can also be physically located outside the crushing device, communicating with the crushing device via wired or wireless means.

[0080] Figure 7 A schematic diagram of a control system according to yet another embodiment of the present invention is shown. Figure 7 The system shown is, for example, Figure 6 This is a specific implementation of the control system shown.

[0081] like Figure 7 As shown, the control system includes a detection circuit 710 and a control circuit 720. The detection circuit 710 includes a sensor 712 for sensing the magnitude of the generated electrical signal. As an example, the sensor 712 is a current sensor for sensing the magnitude of the current flowing through it. The crushing component and the adjusting component of the crushing device are configured as part of the detection circuit 710, and when they come into contact, the detection circuit 710 forms a closed loop, thereby causing a significant increase in current or a peak. In some embodiments, the sensor 712 is a voltage sensor for sensing a voltage or level signal. As an example, the crushing component and the adjusting component of the crushing device are configured as part of the detection circuit 710, and when they come into contact, the detection circuit 710 forms a closed loop, thereby the voltage sensor detects a changed voltage signal, such as an increase in voltage or a voltage peak. This can be achieved, for example, by detecting the terminal voltage of an element (e.g., a resistive element) connected in the detection circuit. It is also possible to detect the voltage of other circuit elements or circuit nodes. Other types of sensors are also possible. In some embodiments, the contact or relative position of the crushing component and the adjusting component of the crushing device is monitored by detecting electrical signals other than voltage and current.

[0082] In some embodiments, when the crushing component and the adjusting component come into contact, the crushing component continues to rotate for various reasons (e.g., its own inertia or system settings), and the contact is intermittent, resulting in one or more current spikes, one or more voltage spikes, or other detectable electrical signals in the detection circuit. Spikes typically represent an increase in the amplitude of a physical quantity. Current spikes or voltage spikes can be positive or negative.

[0083] The control circuit 720 receives detection results from the detection circuit 710, such as current or voltage values, analyzes the detection results, and responds accordingly. For example, when the analysis indicates that the crushing component and the adjusting component are in contact, a control signal is issued to stop providing power to the crushing component.

[0084] The control circuit 720 determines whether contact has occurred through appropriate analysis. For example, if a certain number (e.g., 2, 5, 10, or more) of current spikes occur within a certain time period (e.g., within seconds or millimeters), the control circuit 720 determines that contact has occurred. Alternatively, the electrical signal can be compared to a predetermined threshold, and contact can be determined based on the comparison result. For example, in some embodiments, the control circuit 720 compares the detected current value to a predetermined current threshold; if the current value is greater than the predetermined current threshold, contact is considered to have occurred. Similarly, if a certain number (e.g., 2, 5, 10, or more) of low-level signals occur within a certain time period (e.g., within seconds or millimeters), the control circuit 720 determines that contact has occurred. In some embodiments, the control circuit 720 compares the detected voltage value to a predetermined voltage threshold; if the voltage value is greater than the predetermined voltage threshold, contact is considered to have occurred. Other criteria for determining contact are also possible.

[0085] Although the example described here is the detection of an increase in current or voltage, in some embodiments, it is also possible to determine the occurrence of contact by detecting a decrease in current or voltage, with appropriate circuit design.

[0086] exist Figure 7 The control system shown also includes an alarm circuit 730. When the crushing component and the adjusting component come into contact, the alarm circuit 730 can emit an alarm signal. The alarm signal can be used to alert the user or to trigger an internal circuit response, thereby increasing operational safety. The alarm signal can be a visual signal, such as color, flashing lights, or combinations thereof. The alarm signal can also be an audible signal, such as a long beep, a short beep, etc. In some embodiments, the alarm circuit emits both audible and visual signals simultaneously to further enhance the alarm effect and increase applicability to different users (e.g., users with visual or hearing impairments).

[0087] In addition, the control system shown also includes a user interface 740 to facilitate interaction with the user. As an example, the user interface 740 includes a calibration mode 741, reverse operation 742, contact 743, blockage 744, overload 745, power level 746, and operating speed 747. As an example, calibration mode 741 can be used to place the crushing device in calibration mode, thereby activating the detection circuit; reverse operation 742 can be used to reverse the operation of the crushing component; contact 743 can be used to indicate contact between the crushing component and the adjustment component; blockage 744 can be used to indicate blockage of the operating space (e.g., due to reduced crushing efficiency); overload 745 can be used to indicate overload of the crushing device (e.g., due to excessive material); power level 746 can be used to indicate the power level of the crushing device's power supply (e.g., battery pack); and operating speed 747 can be used to change the operating speed of the crushing component.

[0088] These exemplary user interfaces can be buttons, icons, or other suitable forms. One or more of the user interfaces can be used to receive user input, thereby manipulating one or more components or physical quantities of the crushing device, such as calibration mode 741, operating speed 747, etc. One or more of the user interfaces can be used to provide output to the user, such as displaying the status or parameters of one or more components of the crushing device, such as contact 743, overload 745, etc. When displayed as output, it can take an appropriate form, such as color, multiple color combinations and changes, flashing, color bar length and changes, etc., and may also be accompanied by sound signals.

[0089] In some embodiments, the power supply to the crushing device is automatically cut off when triggered, for example, by contact 743 or overload 745. When triggered, for example, by blockage 744, the crushing component is automatically reversed, or rotated alternately in both directions for a period of time to perform anti-blockage operation.

[0090] According to another aspect of the invention, Figure 8 A flowchart illustrating a control method according to some embodiments of the present invention is shown. The illustrated control method can, for example, be used to manipulate... Figure 6 or Figure 7 The control system described. The illustrated control method can be used, for example, for a reference... Figure 1A , 1B The crushing devices 5A and 5B are controlled or operated.

[0091] In box 82, it is detected whether the adjusting component of the pulverizing device is in contact with the pulverizing component. This can be done, for example, by detecting the current or voltage value of the circuit and determining whether the contact has occurred using the current value or current curve, or the voltage value or voltage curve. Optionally, the pulverizing component and the adjusting component are electrically part of the circuit being detected, which is advantageous for reducing circuit complexity. This detection can occur during operation of the pulverizing device or can be initiated by entering a calibration mode.

[0092] In block 84, a response is initiated upon the occurrence of contact. For example, an alarm signal is issued upon detection of contact between the adjusting component and the crushing component; the alarm signal may be a visual signal, an audible signal, or a combination of both. In some embodiments, the crushing device is switched to normal mode. Upon detection of such contact, power to the crushing mechanism is stopped, for example, by disconnecting battery power to the motor or by disconnecting the electrical connection between the motor and the crushing mechanism.

[0093] In some embodiments, the pulverizing device is switched to calibration mode, and then the pulverizing component is stopped or reversed (i.e., the direction of operation of the pulverizing component is opposite to that in normal mode), and the distance between the adjusting component and the pulverizing component is adjusted automatically or manually.

[0094] In some embodiments, the crushing device must first be placed in calibration mode before the operating space can be adjusted, although this requirement is unnecessary for some other embodiments.

[0095] Figure 9 A flowchart illustrating a control method according to further embodiments of the present invention is provided. The illustrated method may be, for example, […]. Figure 8 A specific implementation of the illustrated method.

[0096] In box 90, the crushing device is switched from a first mode to a second mode. In the first mode, the crushing component rotates in a first direction of rotation; in the second mode, the crushing component rotates in a second direction of rotation opposite to the first direction of rotation. The first mode is, for example, a normal mode, and the second mode is, for example, a calibration mode. The first direction of rotation is, for example, counterclockwise, and the second direction of rotation is, for example, clockwise. The switching operation can be achieved, for example, by triggering the calibration mode button on the user interface.

[0097] In box 92, the adjusting component is automatically or manually driven to move at least a portion of it toward the crushing component, thereby reducing the operating space. The adjusting component and the crushing component are, for example, references... Figure 2 , 3A One of the adjustment components and one of the crushing components illustrated in 3B and 4.

[0098] In box 94, check whether the adjusting component is in contact with the crushing component. For example, it can be done by... Figure 6 or Figure 7 The illustrated control system performs the detection. In block 96, upon this contact, power to the crushing component is stopped (if the crushing component is reversing). This can be achieved, for example, by... Figure 6 or Figure 7 The illustrated control circuit issues a command to disconnect the power supply to the motor. In block 98, at least a portion of the adjusting component is moved away from the crushing component, either automatically or manually, to increase the operating space. In automatic mode, it moves a predetermined distance away. In manual mode, the user can observe the operating space through window 560. Thus, the adjusting component is no longer in contact with the crushing component, and the operating space can be adjusted to a suitable level according to actual needs.
