Description

Technical Field

[0001] This utility model relates to the field of chainsaw technology, and more specifically, to a chainsaw. Background Technology

[0002] Currently, chainsaws are widely used cutting tools, primarily for cutting materials such as wood, concrete, bricks, and stone. Their core cutting principle relies on the lateral movement of blades arranged in a staggered pattern on a chain to achieve the cutting function.

[0003] In existing technology, when a chainsaw is working, the friction between the chain and the workpiece, as well as the contact between the chain and other components, generate a significant amount of heat. To ensure the chainsaw operates normally and to extend its service life, a lubrication system is typically used to dissipate heat and reduce friction.

[0004] However, when faced with specific cutting materials or working conditions, users cannot adjust the amount of oil pumped in a timely manner or control the amount of oil pumped within a certain range according to actual needs. This limits the flexibility of using the chainsaw and affects cutting efficiency and user experience. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a chainsaw that solves the problem that the lubrication system pump oil volume cannot be adjusted according to actual needs in the prior art.

[0006] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0007] A chainsaw includes: a cutting assembly comprising a drive unit and a cutting structure driven and connected to the drive unit; a lubrication system comprising a liquid supply device and a pump body, the pump body being used to pump lubricating medium stored in the liquid supply device into the cutting assembly; and a pump volume adjustment assembly comprising a first adjustment structure electrically connected to the pump body, the first adjustment structure having multiple adjustment modes, the different adjustment modes of the first adjustment structure corresponding to different pump volumes. By adding a pump volume adjustment assembly to the chainsaw, the first adjustment structure being electrically connected to the pump body, the first adjustment structure having multiple adjustment modes, and the first adjustment structure corresponding to different pump volumes in different adjustment modes, it is ensured that the lubrication system can provide an appropriate supply of lubricating medium when the chainsaw is cutting different materials (such as dry wood, wet wood, ice, hard plastic, etc.), avoiding the problems of insufficient or excessive lubrication, effectively extending the service life of the cutting assembly and the performance of the chain, and thus solving the problem in the prior art where the pump volume of the lubrication system is difficult to adjust according to actual needs. In this way, the multiple adjustment modes of the first adjustment structure provide users with more flexible operating options, allowing them to adjust the pump oil volume at any time according to actual needs, which not only improves the cutting efficiency of the chainsaw but also enhances the user experience for operators.

[0008] Furthermore, the chainsaw also includes a chain speed adjustment component, comprising a second adjustment structure electrically connected to a drive unit. The second adjustment structure has multiple speed adjustment modes, each corresponding to a different output power of the drive unit, thereby adjusting the chain speed of the cutting structure. The second adjustment structure provides multiple speed adjustment modes, each with a different output power of the drive unit, directly affecting the chain speed of the cutting structure. This allows users to precisely adjust the chain speed based on factors such as material hardness, moisture content, and cutting difficulty to achieve optimal cutting results and efficiency.

[0009] Furthermore, the first adjustment mechanism is a button or a knob; and / or, the second adjustment mechanism is a button or a knob. Using the button or knob, users can instantly change the pump oil volume and / or chain speed without complex menu navigation or setting adjustments, ensuring efficient switching between different cutting tasks. Simultaneously, the knob offers fine-tuning capabilities, allowing users to fine-tune between multiple preset modes for more precise control of the pump oil volume and / or chain speed, especially when fine-tuning is required to adapt to specific materials or working conditions.

[0010] Furthermore, the chainsaw also includes a display panel, with the first and second adjustment structures spaced apart on the panel. The display panel integrates feedback on oil pump volume and chain speed adjustment. Through intuitive displays on the panel (such as output power bar, chain speed indicator, and oil pump mode indicator), users can clearly understand the chainsaw's current working status and settings, allowing for more precise operation via the first and second adjustment structures, thus improving work efficiency and safety. Simultaneously, the spaced arrangement of the first and second adjustment structures on the display panel clearly defines the operating area, reducing the possibility of misoperation.

[0011] Furthermore, the first adjustment structure is a first button, allowing switching between different adjustment modes of the first adjustment structure by pressing the first button; and / or, the second adjustment structure is a second button, allowing switching between different speed adjustment modes of the second adjustment structure by pressing the second button. Switching between different adjustment modes of the first adjustment structure by pressing the first button and switching between different speed adjustment modes of the second adjustment structure by pressing the second button reduces the operational difficulty for staff and improves the user experience.

[0012] Furthermore, the chainsaw also includes: a control module electrically connected to both the drive unit and the pump body; and a power supply module supplying power to the drive unit, control module, and / or pump body. When the power supply module's charge level is less than or equal to a preset charge level, the control module controls the drive unit to operate the cutting structure at a minimum chain speed. When the power supply module's charge level falls below the preset charge level, the control module automatically adjusts the drive unit's output to ensure the cutting structure operates at the minimum chain speed. This intelligent energy management strategy ensures that the chainsaw can still operate safely when the power is insufficient, preventing accidental injury or equipment damage caused by sudden power outages.

[0013] Furthermore, the first adjustment structure also features a shut-off mode and multiple flow adjustment modes, including an economic mode, a normal mode, and an enhanced mode that sequentially increase the pump's delivery capacity. These modes are switched between by repeatedly pressing the first button. Users can select the most suitable pumping mode based on the characteristics of the cutting material and the specific needs of the working environment. The economic mode is suitable for low-load or low-friction cutting, the normal mode is suitable for most ordinary working conditions, the enhanced mode provides sufficient lubrication for high-load or high-friction situations, and the shut-off mode completely stops pumping, avoiding unnecessary lubrication and lubricant waste, providing high flexibility and control precision.

[0014] Furthermore, along the direction of adjustment where the pump output gradually increases or decreases, the output difference between two adjacent adjustment modes is consistent. By setting a consistent output difference, users can achieve more precise control when adjusting the pump oil volume, avoiding over- or under-lubrication problems caused by irregular output changes, and ensuring optimal lubrication for the chain and cutting section under any operating conditions. Simultaneously, the uniform adjustment step size makes the adjustment process more intuitive; users can easily determine the current pump oil volume based on the information on the display panel without complex calculations or estimations, improving operational convenience and efficiency.

[0015] Furthermore, multiple speed adjustment modes include a low-speed mode, a medium-speed mode, and a high-speed mode, with the chain speed increasing sequentially. When the chainsaw is in its initial state, the chain speed adjustment component is in low-speed mode. By repeatedly pressing the second button, the chain speed adjustment component can switch between medium-speed, high-speed, and low-speed modes. Users can switch between the three chain speed modes with simple button operations according to the actual working environment and cutting needs. The low-speed mode is suitable for fine cutting or low-load work, the medium-speed mode is suitable for most regular cutting tasks, and the high-speed mode is for high-load or fast-cutting scenarios. This flexibility improves the chainsaw's adaptability and efficiency under different working conditions. At the same time, the information on the display panel allows users to clearly understand the current chain speed mode, helping them make more accurate operating decisions. The user-friendly interface and intuitive information enhance the user experience.

[0016] Furthermore, along the speed adjustment direction where the chain speed gradually increases or decreases, the chain speed difference between two adjacent speed adjustment modes is consistent. This consistent chain speed difference provides more precise speed adjustment capabilities, allowing users to control the chainsaw's chain speed more accurately to adapt to cutting materials of varying hardness or density, thereby improving cutting precision and efficiency. Simultaneously, the consistent chain speed difference simplifies the user's operation of the chain speed adjustment components (such as the second button), enabling users to easily predict chain speed changes after each button press, thus improving operational convenience and user-friendliness.

[0017] Furthermore, the drive device is a motor, and the chainsaw also includes: a first detection device, which detects the operating parameters of the motor. If the operating parameters exceed a first preset range, the chainsaw is determined to be under load; if the operating parameters are within the first preset range and remain for a first time period t1, the chainsaw is determined to be under no-load. Alternatively, the first detection device detects the working parameters of the cutting structure. If the working parameters exceed a second preset range, the chainsaw is determined to be under load; if the working parameters are within the second preset range and remain for a second time period t2, the chainsaw is determined to be under no-load. The operating parameters include at least one of current, motor speed, motor duty cycle, and motor temperature; the working parameters include at least one of chain temperature, chain vibration frequency, and chain vibration amplitude. The first detection device can monitor the operating parameters of the motor or the working parameters of the cutting structure in real time, quickly identifying the load state of the chainsaw. When the load increases, the chainsaw can adjust its operating parameters in a timely manner, such as increasing the pump oil volume or increasing the chain speed, to ensure cutting efficiency and equipment safety, and reduce wear on the chain and motor.

[0018] Furthermore, the chainsaw also includes: a first display device for displaying the current speed adjustment mode of the chain speed adjustment component; and / or, a second display device for displaying the current flow rate adjustment mode of the pump volume adjustment component. The first and second display devices provide real-time visual feedback to the user, clearly displaying the chainsaw's current chain speed mode and pump volume mode, enabling the user to immediately understand the chainsaw's working status and avoiding inefficiencies or safety accidents caused by misoperation or uncertainty about the equipment's status.

[0019] Furthermore, the lubrication system also includes: a second detection device for detecting the amount of lubricating medium in the supply device; an alarm module; and a control module connected to both the second detection device and the alarm module. When the detection value of the second detection device is less than or equal to a preset value, the control module controls the alarm module to issue an alarm signal. The second detection device monitors the lubricating medium level in the supply device in real time. When the detection value drops to a preset low threshold, the control module triggers the alarm module, promptly alerting the user to insufficient lubricating medium. This helps users replenish lubricating medium in advance, preventing overheating, increased wear, or performance degradation due to insufficient lubrication, thus extending the chainsaw's service life.

[0020] Furthermore, the lubrication system also includes: a first pipeline, through which the outlet of the liquid supply device is connected to the input end of the pump body; and a second pipeline, through which the output end of the pump body is connected; wherein, the second detection device is installed within the first pipeline. Directly connecting the liquid supply device to the pump body via the first pipeline ensures the continuity of the lubricating medium from storage to transmission to final application, reducing delays and losses during transport. This guarantees timely and accurate lubrication of the chainsaw in any speed control mode, improving the service life of the chain and guide plates, and reducing frictional losses.

[0021] Furthermore, the first adjustment structure is a first knob, and the pump volume adjustment assembly also includes a volume adjustment module, which is set in the control circuit of the pump body. A first ring resistor is provided at the end of the first knob. The first ring resistor rotates synchronously with the first knob, and the volume adjustment input terminal of the volume adjustment module is contacted with the first ring resistor. And / or, the second adjustment structure is a second knob, and the chain speed adjustment assembly also includes a speed adjustment module, which is set in the control circuit of the drive device. A second ring resistor is provided at the end of the second knob. The second ring resistor rotates synchronously with the second knob, and the speed adjustment input terminal of the speed adjustment module is contacted with the second ring resistor.

[0022] To achieve the above objectives, another embodiment of this utility model provides the following technical solution:

[0023] A chainsaw includes: a cutting assembly comprising a drive unit and a cutting structure driven and connected to the drive unit; a lubrication system comprising a supply device and a pump body, the pump body being used to pump lubricating medium stored in the supply device to the cutting assembly; a pump volume adjustment assembly comprising a first adjustment structure electrically connected to the pump body, the first adjustment structure having a closed mode and multiple adjustment modes, different adjustment modes of the first adjustment structure corresponding to different delivery volumes of the pump body; a chain speed adjustment assembly comprising a second adjustment structure electrically connected to the drive unit, the second adjustment structure having multiple speed adjustment modes, different speed adjustment modes of the second adjustment structure corresponding to different output power of the drive unit to adjust the chain speed of the cutting structure; and a control module that matches the adjustment mode of the pump volume adjustment assembly with the speed adjustment mode of the chain speed adjustment assembly. The control module can intelligently match the adjustment mode of the pump volume adjustment assembly with the speed adjustment mode of the chain speed adjustment assembly, ensuring a dynamic balance between the chain speed and the pump oil volume, thereby avoiding insufficient or excessive lubrication caused by mismatch between the pump oil volume and the chain speed, improving the chainsaw cutting efficiency and reducing energy waste. Meanwhile, the first adjustment structure (pump volume adjustment component) and the second adjustment structure (chain speed adjustment component) allow users to flexibly switch between the off mode and multiple volume and speed adjustment modes, meeting the personalized operation requirements of different cutting needs and working environments, and enhancing the versatility and adaptability of the chainsaw.

[0024] Furthermore, the drive device is a motor, and the chainsaw also includes: a first detection device, which detects the operating parameters of the motor. If the operating parameters exceed a first preset range, the chainsaw is determined to be under load; if the operating parameters are within the first preset range and remain for a first time period t1, the chainsaw is determined to be under no-load. Alternatively, the first detection device detects the working parameters of the cutting structure. If the working parameters exceed a second preset range, the chainsaw is determined to be under load; if the working parameters are within the second preset range and remain for a second time period t2, the chainsaw is determined to be under no-load. The operating parameters include at least one of current, motor speed, motor duty cycle, and motor temperature; the working parameters include at least one of chain temperature, chain vibration frequency, and chain vibration amplitude. The first detection device can monitor the operating parameters of the motor or the working parameters of the cutting structure in real time, quickly identifying the load state of the chainsaw. When the load increases, the chainsaw can adjust its operating parameters in a timely manner, such as increasing the pump oil volume or increasing the chain speed, to ensure cutting efficiency and equipment safety, and reduce wear on the chain and motor.

[0025] Furthermore, when the chainsaw is under load, multiple speed control modes and multiple flow rate control modes are set one-to-one and positively correlated. Under load, the matched chain speed and pump oil volume can avoid energy waste. There is no need for excessive pump oil volume to cope with low chain speed working conditions, and vice versa. This helps to optimize energy utilization while ensuring equipment performance and reducing operating costs.

[0026] Furthermore, multiple flow adjustment modes include an economic mode, a normal mode, and an enhanced mode, where the pump's delivery capacity increases sequentially. By pressing the first adjustment structure repeatedly, the pump flow adjustment component can switch between these modes: economic, normal, enhanced, and off. Users can select the most suitable pumping mode based on the characteristics of the cutting material and the specific needs of the working environment. The economic mode is suitable for low-load or low-friction cutting; the normal mode is suitable for most ordinary working conditions; the enhanced mode provides sufficient lubrication for high-load or high-friction situations; and the off mode completely stops pumping, avoiding unnecessary lubrication and lubricant waste, providing high flexibility and control precision.

[0027] Furthermore, multiple speed adjustment modes include a low-speed mode, a medium-speed mode, and a high-speed mode, with the chain speed increasing sequentially. When the chainsaw is in its initial state, the chain speed adjustment component is in low-speed mode. By repeatedly pressing the second adjustment mechanism, the chain speed adjustment component can switch between medium-speed, high-speed, and low-speed modes. Users can switch between the three chain speed modes with simple button operations according to the actual working environment and cutting needs. The low-speed mode is suitable for fine cutting or low-load work, the medium-speed mode is suitable for most regular cutting tasks, and the high-speed mode is for high-load or fast-cutting scenarios. This flexibility improves the chainsaw's adaptability and efficiency under different working conditions. At the same time, the information on the display panel allows users to clearly understand the current chain speed mode, helping them make more accurate operating decisions. The user-friendly interface and intuitive information enhance the user experience.

[0028] This invention offers the following advantages: By adding a pump volume adjustment component to the chainsaw, with the first adjustment structure electrically connected to the pump body, and the first adjustment structure having multiple adjustment modes, the pump body delivers different volumes under each mode. This ensures that the lubrication system provides the appropriate lubricant supply when the chainsaw cuts different materials (such as dry wood, wet wood, ice, hard plastic, etc.), avoiding insufficient or excessive lubrication. This effectively extends the service life of the cutting components and the performance of the chain, thus solving the problem in existing technologies where the pump volume of the lubrication system cannot be adjusted according to actual needs. In this way, the multiple adjustment modes of the first adjustment structure provide users with more flexible operating options, allowing them to adjust the pump volume at any time according to actual needs. This not only improves the cutting efficiency of the chainsaw but also enhances the user experience. Attached Figure Description

[0042] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0043] To address the problem that existing technologies often fail to adjust the oil pump volume of the lubrication system according to actual needs, this invention provides a chainsaw.

[0044] To achieve the above objectives, the technical solution provided in Embodiment 1 of this utility model is as follows:

[0045] like Figures 1 to 3 As shown, this utility model provides a chainsaw, including a cutting assembly, a lubrication system 10, and a pump volume adjustment assembly. The cutting assembly includes a drive device and a cutting structure driven and connected to the drive device. The lubrication system 10 includes a liquid supply device 11 and a pump body 12, which pumps the lubricating medium stored in the liquid supply device 11 into the cutting assembly. The pump volume adjustment assembly includes a first adjustment structure 40, which is electrically connected to the pump body 12. The first adjustment structure 40 has multiple adjustment modes, and different adjustment modes of the first adjustment structure 40 correspond to different delivery volumes of the pump body 12.

[0046] By applying the technical solution of this embodiment, a pump volume adjustment component is added to the chainsaw. The first adjustment structure 40 and the pump body 12 are electrically connected. The first adjustment structure 40 has multiple adjustment modes, and the pump volume of the pump body 12 is different in different adjustment modes. This ensures that the lubrication system 10 can provide just the right amount of lubricating medium when the chainsaw is cutting different materials (such as dry wood, wet wood, ice, hard plastic, etc.), avoiding the problems of insufficient or excessive lubrication. This effectively extends the service life of the cutting components and the performance of the chain, thereby solving the problem in the prior art where it is easy to work but impossible to adjust the pump oil volume of the lubrication system according to actual needs. In this way, the multiple adjustment modes of the first adjustment structure 40 provide users with more flexible operating options, allowing them to adjust the pump oil volume at any time according to actual needs. This not only improves the cutting efficiency of the chainsaw but also enhances the user experience for operators.

[0047] Specifically, when a chainsaw cuts dry wood and wet wood, the load is relatively small when cutting dry wood, but the amount of lubricating oil required is relatively large; the load is relatively high when cutting wet wood, but the amount of lubricating oil required is relatively small; the load is large when cutting ice, but the amount of lubricating oil required is small; when cutting materials that generate dust, the debris carries away a large amount of lubricating oil, so even with a small load, the amount of lubricating oil required is relatively high; when cutting hard materials, such as hard plastics, although the load is large, the amount of lubricating oil required is not particularly high, but if too much oil is pumped, oil splattering is likely to occur.

[0048] In this embodiment, the adjustment mode does not change automatically due to changes in chain speed. The adjustment mode can only be switched by pressing the first adjustment structure 40 to meet the needs of diverse scenarios or working conditions.

[0049] In this embodiment, the first adjustment structure 40 is electrically connected to the control module, and the control module is electrically connected to the pump body 12, so as to realize the electrical connection between the first adjustment structure 40 and the pump body 12.

[0050] like Figure 1 and Figure 2 As shown, the chainsaw also includes a chain speed adjustment component. This component includes a second adjustment structure 30, which is electrically connected to the drive unit. The second adjustment structure 30 has multiple speed adjustment modes, each corresponding to a different output power of the drive unit, thus adjusting the chain speed of the cutting structure. In this way, the second adjustment structure 30 provides multiple speed adjustment modes, each with a different output power of the drive unit, directly affecting the chain speed of the cutting structure. This allows users to precisely adjust the chain speed according to factors such as material hardness, moisture content, and cutting difficulty to achieve optimal cutting results and efficiency.

[0051] In this embodiment, when the chainsaw is under low load or cutting softer materials, the user can select a low output power mode to reduce the chain speed, thereby reducing energy consumption and extending the chainsaw's service life. When the chainsaw is under high load or requires rapid cutting, a high output power mode can be selected to increase the chain speed to meet higher work demands while ensuring sufficient power for the chainsaw. Thus, the multiple speed adjustment modes of the second adjustment structure 30 provide users with a wide range of chain speed adjustments, allowing the chainsaw to adapt to more diverse working environments and user needs. Users can quickly switch chain speeds according to actual conditions, improving operational flexibility and convenience.

[0052] Optionally, the first adjustment structure 40 is a button or a knob; and / or, the second adjustment structure 30 is a button or a knob. In this way, users can instantly change the pump oil volume and / or chain speed via the button or knob, without the need for complex menu navigation or setting adjustments, ensuring efficient switching of the chainsaw between different cutting tasks. At the same time, the knob has fine-tuning capabilities, allowing users to fine-tune between multiple preset modes to achieve more precise control of the pump oil volume and / or chain speed, especially when fine-tuning is required to adapt to specific materials or working conditions.

[0053] In this embodiment, the first adjustment structure 40 is a first button and the second adjustment structure 30 is a second button, so that the pump oil volume can be adjusted by pressing the first button and the chain speed can be adjusted by pressing the second button, thereby reducing the difficulty of operation for the operator and improving the user experience.

[0054] Specifically, the chain speed is adjusted to three levels via the second button: 18m / s, 22m / s, and 26m / s. The chainsaw operates in low speed mode (18m / s) by default when powered on. Pressing the second button once switches to medium speed mode, pressing it a second time switches to high speed mode, and pressing it a third time returns to low speed mode, repeating this process. When the battery level drops below 20%, the chain speed automatically switches to low speed mode to extend battery life.

[0055] likeFigure 1 and Figure 2 As shown, the chainsaw also includes a display panel 20, with a first adjustment structure 40 and a second adjustment structure 30 spaced apart on the display panel 20. In this way, the display panel 20 integrates feedback information on oil pump volume and chain speed adjustment. Through the intuitive displays on the display panel 20 (such as output power energy bar, chain speed gear indicator, oil pump mode indicator, etc.), the user can clearly understand the current working status and settings of the chainsaw, thereby operating it more accurately through the first adjustment structure 40 and the second adjustment structure 30, improving work efficiency and safety. At the same time, the spaced arrangement of the first adjustment structure 40 and the second adjustment structure 30 on the display panel 20 clearly delineates the operating area, reducing the possibility of misoperation.

[0056] In this embodiment, the user can monitor the chainsaw's operating parameters in real time, such as battery power, chain speed, and oil pumping volume, through the display panel 20. The instant feedback of this information allows the user to adjust the oil pumping volume or chain speed in a timely manner according to work needs, so as to adapt to different cutting materials and working conditions and achieve intelligent operation.

[0057] In this embodiment, the first adjustment structure 40 is a first button, allowing switching between different adjustment modes of the first adjustment structure 40 by pressing the first button; and / or, the second adjustment structure 30 is a second button, allowing switching between different speed adjustment modes of the second adjustment structure 30 by pressing the second button. Thus, switching between different adjustment modes of the first adjustment structure 40 by pressing the first button and switching between different speed adjustment modes of the second adjustment structure 30 by pressing the second button reduces the operational difficulty for staff and improves the user experience.

[0058] Optionally, the chainsaw also includes a control module and a power supply module. The control module is electrically connected to both the drive unit and the pump body 12. The power supply module supplies power to the drive unit, the control module, and / or the pump body 12. When the power supply module's charge is less than or equal to a preset charge value, the control module controls the drive unit to operate the cutting structure at the minimum chain speed. Thus, when the power supply module's charge falls below the preset charge value, the control module automatically adjusts the drive unit's output to ensure the cutting structure operates at the minimum chain speed. This intelligent energy management strategy ensures that the chainsaw can still operate safely when the power is insufficient, preventing accidental injury or equipment damage due to sudden power outages.

[0059] In this embodiment, the power supply module supplies power to the drive device and the control module. The drive power for the pump body 12 is provided by the control module, and the power supply for the control module is provided by the power supply module. This electrical connection between the control module, the drive device, and the pump body 12 enables integrated control of the system, simplifies the chainsaw's operation, and improves the overall performance of the equipment and the user's operating experience.

[0060] Optionally, the power supply module is a battery pack.

[0061] In this embodiment, the first adjustment structure 40 also has a shut-off mode. Multiple flow adjustment modes include an economic mode, a normal mode, and an enhanced mode, where the pump body 12's delivery volume increases sequentially. By pressing the first button repeatedly, the pump volume adjustment component can switch between these modes. This allows the user to select the most suitable pumping mode based on the characteristics of the cutting material and the specific needs of the working environment. The economic mode is suitable for low-load or low-friction cutting; the normal mode is suitable for most ordinary working conditions; the enhanced mode provides sufficient lubrication for high-load or high-friction situations; and the shut-off mode completely stops pumping, avoiding unnecessary lubrication and lubricant waste, providing high flexibility and control precision.

[0062] Specifically, the economy mode significantly reduces lubricant consumption, especially when cutting dry materials or operating under light loads. It effectively saves lubricant, reduces energy waste, and extends the operating time after each refill or full tank. For users who frequently use chainsaws, this translates to considerable cost savings. Furthermore, switching between pumping modes, including the off mode, can be accomplished by repeatedly pressing a single first button. This simplifies the user interface, reduces operational complexity, and allows users to easily adjust the pumping volume even when wearing protective gear or with hand impairments, improving operational convenience and efficiency.

[0063] In this embodiment, the output difference between two adjacent adjustment modes is consistent along the direction of gradually increasing or decreasing output of the pump body 12. This consistent output difference allows for more precise control when adjusting the pump oil volume, avoiding over- or under-lubrication issues caused by irregular output changes, and ensuring optimal lubrication for the chain and cutting section under any operating conditions. Simultaneously, the uniform adjustment step size makes the adjustment process more intuitive; users can easily determine the current pump oil volume based on the information on the display panel 20 without complex calculations or estimations, improving operational convenience and efficiency.

[0064] In this embodiment, multiple speed adjustment modes include a low-speed mode, a medium-speed mode, and a high-speed mode, with the chain speed increasing sequentially. When the chainsaw is in its initial state, the chain speed adjustment component is in low-speed mode. By repeatedly pressing the second button, the chain speed adjustment component can switch between medium-speed, high-speed, and low-speed modes. This allows the user to switch between the three chain speed modes with simple button operations according to the actual working environment and cutting needs. The low-speed mode is suitable for fine cutting or low-load work, the medium-speed mode is suitable for most regular cutting tasks, and the high-speed mode is for high-load or fast-cutting scenarios. This flexibility improves the chainsaw's adaptability and efficiency under different working conditions. Simultaneously, the information on the display panel 20 allows the user to clearly understand the current chain speed mode, helping them make more accurate operational decisions. The user-friendly interface and intuitive information enhance the user experience.

[0065] Specifically, the low-speed mode is the default mode when starting the chainsaw, which can effectively prevent sudden high-speed operation during startup, reduce vibration and noise during startup, and protect the operator from accidental injury. At the same time, the chain speed adjustment in high-speed mode ensures that the chain can maintain sufficient speed when handling hard materials or high-density wood, reducing the risk of saw jamming or springback.

[0066] In this embodiment, the chain speed difference between two adjacent speed adjustment modes is consistent along the speed adjustment direction where the chain speed gradually increases or decreases. This consistent chain speed difference provides more precise speed adjustment capability, allowing users to control the chainsaw's chain speed more accurately to adapt to cutting materials of different hardness or density, thereby improving cutting precision and efficiency. Simultaneously, the consistent chain speed difference simplifies the user's operation of the chain speed adjustment components (such as the second button), allowing users to easily predict the chain speed change after each button press, improving operational convenience and user-friendliness.

[0067] Optionally, the drive device is a motor, and the chainsaw also includes a first detection device. The first detection device detects the motor's operating parameters. If the operating parameters exceed a first preset range, the chainsaw is determined to be under load; if the operating parameters are within the first preset range and remain for a first time period t1, the chainsaw is determined to be under no-load. Alternatively, the first detection device detects the working parameters of the cutting structure. If the working parameters exceed a second preset range, the chainsaw is determined to be under load; if the working parameters are within the second preset range and remain for a second time period t2, the chainsaw is determined to be under no-load. The operating parameters include at least one of current, motor speed, motor duty cycle, and motor temperature; the working parameters include at least one of chain temperature, chain vibration frequency, and chain vibration amplitude. In this way, the first detection device can monitor the motor's operating parameters or the cutting structure's working parameters in real time, quickly identifying the chainsaw's load state. When the load increases, the chainsaw can adjust its operating parameters in a timely manner, such as increasing the pump oil volume or increasing the chain speed, to ensure cutting efficiency and equipment safety, and reduce wear on the chain and motor.

[0068] In this embodiment, under no-load conditions, the chainsaw can automatically adjust to a low-energy mode, such as reducing the pump oil volume or slowing down the chain speed, to avoid wasting energy when there is no cutting operation. This not only extends the battery or fuel life and reduces operating costs, but also reduces energy consumption, reflecting the design concept of environmental protection and energy saving. Thus, monitoring motor operating parameters, such as current, speed, and temperature, helps prevent overload, overheating, and other situations that may lead to equipment failure or accidents, enhancing the chainsaw's safety performance under various working conditions. Simultaneously, monitoring chain operating parameters can promptly detect chain abnormalities, such as excessively high temperature or abnormally increased vibration, further improving operational safety.

[0069] Specifically, after the chainsaw is turned on, it operates in low-speed mode. Pressing the first button activates the chainsaw's oil pump function. Simultaneously, the control module detects the current chain speed and pumps oil in normal mode, ensuring lubricating oil is delivered to the guide plate and chain as soon as the chain begins to move. This reduces friction and wear, improves cutting efficiency, and extends chain life. When the chainsaw is not under load or in operation, the operator can press the first button at any time to turn off the oil pump function, preventing excessive oil pumping and dripping under no-load conditions. Alternatively, after the chainsaw starts pumping oil, the control module actively detects the chainsaw's operating status. If the oil pump function remains in an no-load state after startup and for a period of time (t), it automatically shuts off. If a load state is detected, the current oil pumping mode is maintained, continuing to pump oil for the chainsaw.

[0070] Optionally, the chainsaw further includes a first display device for displaying the current speed adjustment mode of the chain speed adjustment component; and / or, the chainsaw further includes a second display device for displaying the current flow rate adjustment mode of the pump volume adjustment component. In this way, the first and second display devices provide the user with real-time visual feedback, clearly displaying the chainsaw's current chain speed mode and pump volume mode, enabling the user to immediately understand the chainsaw's working status and avoiding inefficiencies or safety accidents caused by misoperation or uncertainty about the equipment's status.

[0071] Optionally, the first display device and / or the second display device is a display screen.

[0072] In this embodiment, the chainsaw also includes a first display device and a second display device. The first display device is used to display the current speed adjustment mode of the chain speed adjustment component, and the second display device is used to display the current volume adjustment mode of the pump volume adjustment component.

[0073] like Figure 3 As shown, the lubrication system 10 also includes a second detection device 50, an alarm module, and a control module. The second detection device 50 detects the amount of lubricating medium in the supply device 11. The control module is connected to both the second detection device 50 and the alarm module; when the detected value of the second detection device 50 is less than or equal to a preset value, the control module controls the alarm module to issue an alarm signal. Thus, the second detection device 50 monitors the lubricating medium level in the supply device 11 in real time. When the detected value drops to a preset low threshold, the control module triggers the alarm module, promptly alerting the user to insufficient lubricating medium. This helps the user replenish the lubricating medium in advance, avoiding overheating, increased wear, or performance degradation due to insufficient lubrication, and extending the service life of the chainsaw.

[0074] Optionally, the alarm signal may be an audible signal and / or a photoelectric signal.

[0075] In this embodiment, the consumption rate of the lubricating medium may vary under different working conditions and cutting materials. The real-time monitoring function of the second detection device 50 enables the chainsaw to maintain optimal lubrication in various working environments, improving the environmental adaptability and versatility of the equipment.

[0076] like Figure 3As shown, the lubrication system 10 also includes a first pipeline 60 and a second pipeline 70. The outlet of the liquid supply device 11 is connected to the input end of the pump body 12 through the first pipeline 60, and the output end of the pump body 12 is connected to the second pipeline 70. The second detection device 50 is located within the first pipeline 60. In this way, by directly connecting the liquid supply device 11 and the pump body 12 through the first pipeline 60, the continuity of the lubricating medium from storage to transmission to final application is ensured, reducing delays and losses during the transportation process. This guarantees timely and accurate lubrication of the chainsaw in any speed control mode, improves the service life of the chain and guide plate, and reduces frictional wear.

[0077] Specifically, the second detection device 50 is installed within the first pipeline 60, enabling real-time monitoring of the lubricating medium flow, including flow rate and liquid level. This allows for effective identification of whether the lubricating medium is sufficient and whether there are leaks or blockages, helping the chainsaw maintain optimal lubrication under any operating conditions and preventing equipment damage due to insufficient lubricant. Simultaneously, when the second detection device 50 detects that the lubricating medium level is below a preset value, it quickly triggers an alarm mechanism through the control module, reminding the user to replenish the lubricating medium promptly. This rapid response mechanism prevents the chain and guide plates from operating without lubrication, reducing sudden equipment failures and improving operational continuity and safety.

[0078] To achieve the above objectives, the technical solution provided in Embodiment 2 of this utility model is as follows:

[0079] In this embodiment, the chainsaw includes a cutting assembly, a lubrication system 10, a pump volume adjustment assembly, a chain speed adjustment assembly, and a control module. The cutting assembly includes a drive unit and a cutting structure driven and connected to the drive unit. The lubrication system 10 includes a liquid supply device 11 and a pump body 12, which pumps the lubricating medium stored in the liquid supply device 11 into the cutting assembly. The pump volume adjustment assembly includes a first adjustment structure 40, electrically connected to the pump body 12. The first adjustment structure 40 has a closed mode and multiple adjustment modes, with different adjustment modes corresponding to different delivery volumes from the pump body 12. The chain speed adjustment assembly includes a second adjustment structure 30, electrically connected to the drive unit. The second adjustment structure 30 has multiple speed adjustment modes, with different speed adjustment modes corresponding to different output power of the drive unit, thereby adjusting the chain speed of the cutting structure. The control module matches the adjustment mode of the pump volume adjustment assembly with the speed adjustment mode of the chain speed adjustment assembly.

[0080] By applying the technical solution of this embodiment, the control module can intelligently match the adjustment mode of the pump volume adjustment component according to the speed adjustment mode of the chain speed adjustment component, ensuring a dynamic balance between the chain speed and the pump oil volume. This avoids insufficient or excessive lubrication caused by a mismatch between the pump oil volume and the chain speed, improving the chainsaw cutting efficiency and reducing energy waste. Simultaneously, the first adjustment structure 40 (pump volume adjustment component) and the second adjustment structure 30 (chain speed adjustment component) allow users to flexibly switch between a closed mode and various adjustment modes, meeting the personalized operation requirements of different cutting needs and working environments, and enhancing the chainsaw's versatility and adaptability.

[0081] In this embodiment, the driving device is a motor, and the chainsaw also includes a first detection device. The first detection device detects the motor's operating parameters. If the operating parameters exceed a first preset range, the chainsaw is determined to be under load; if the operating parameters are within the first preset range and remain for a first time period t1, the chainsaw is determined to be under no-load. Alternatively, the first detection device detects the working parameters of the cutting structure. If the working parameters exceed a second preset range, the chainsaw is determined to be under load; if the working parameters are within the second preset range and remain for a second time period t2, the chainsaw is determined to be under no-load. The operating parameters include at least one of current, motor speed, motor duty cycle, and motor temperature; the working parameters include at least one of chain temperature, chain vibration frequency, and chain vibration amplitude. Thus, the first detection device can monitor the motor's operating parameters or the cutting structure's working parameters in real time, quickly identifying the chainsaw's load state. When the load increases, the chainsaw can adjust its operating parameters promptly, such as increasing the pump oil volume or increasing the chain speed, to ensure cutting efficiency and equipment safety, and reduce wear on the chain and motor.

[0082] In this embodiment, when the chainsaw is under load, multiple speed control modes and multiple flow rate control modes are set one-to-one and positively correlated. This ensures that the matched chain speed and oil pump volume prevent energy waste under load. Excessive oil pumping is unnecessary for low chain speed operation, and vice versa. This helps to optimize energy utilization while ensuring equipment performance, thus reducing operating costs.

[0083] In this embodiment, multiple flow adjustment modes include an economic mode, a normal mode, and an enhanced mode, where the pump body 12 sequentially increases its delivery capacity. This is achieved by repeatedly pressing the first adjustment structure 40, causing the pump flow adjustment component to switch between these modes. This allows the user to select the most suitable pumping mode based on the characteristics of the cutting material and the specific requirements of the working environment. The economic mode is suitable for low-load or low-friction cutting; the normal mode is suitable for most ordinary working conditions; the enhanced mode provides sufficient lubrication for high-load or high-friction situations; and the enhanced mode completely stops pumping, avoiding unnecessary lubrication and lubricant waste, thus providing high flexibility and control precision.

[0084] In this embodiment, multiple speed adjustment modes include a low-speed mode, a medium-speed mode, and a high-speed mode with progressively increasing chain speeds. When the chainsaw is in its initial state, the chain speed adjustment component is in low-speed mode. By repeatedly pressing the second adjustment structure 30, the chain speed adjustment component can switch between medium-speed, high-speed, and low-speed modes. This allows the user to switch between the three chain speed modes with simple button operations, depending on the actual working environment and cutting needs. The low-speed mode is suitable for fine cutting or low-load work, the medium-speed mode is suitable for most regular cutting tasks, and the high-speed mode is for high-load or fast-cutting scenarios. This flexibility improves the chainsaw's adaptability and efficiency under different working conditions. Simultaneously, the information on the display panel allows the user to clearly understand the current chain speed mode, helping them make more accurate operational decisions. The user-friendly interface and intuitive information enhance the user experience.

[0085] Specifically, when the chainsaw enters a load or working state, the chainsaw adaptively matches the current adjustment mode to the economy mode (ECO mode). When the operator presses the second button, the chain speed switches to the medium speed mode (22m / s), and the matching adjustment mode automatically switches to the normal mode (Normal mode). When the operator presses the second button again, the chain speed switches to the high speed mode (26m / s), and the matching adjustment mode automatically switches to the enhanced mode (Turbo mode). Pressing the second button again returns to the low speed mode, and the adjustment mode also returns to the economy mode (ECO mode).

[0086] To achieve the above objectives, the technical solution provided in Embodiment 3 of this utility model is as follows:

[0087] In this embodiment, the first adjustment structure 40 is a button and the second adjustment structure 30 is a knob, so that the pump oil volume can be adjusted by pressing the button and the chain speed can be adjusted by turning the knob, thereby reducing the difficulty of operation for the operator and improving the user experience.

[0088] To achieve the above objectives, the technical solution provided in Embodiment 4 of this utility model is as follows:

[0092] To achieve the above objectives, the technical solution provided in Embodiment Six of this utility model is as follows:

[0093] In this embodiment, the chainsaw also includes a control module and a power supply module. The control module is electrically connected to both the drive unit and the pump body 12. The power supply module supplies power to the drive unit, the control module, and the pump body 12. Thus, the pump body 12 is powered through the power supply module to ensure stable operation.

[0094] To achieve the above objectives, the technical solution provided in Embodiment Seven of this utility model is as follows:

[0095] Optionally, the first adjustment structure 40 is a first knob, and the pump volume adjustment assembly further includes a volume adjustment module. The volume adjustment module is located in the control circuit of the pump body 12. A first ring resistor is provided at the end of the first knob. The first ring resistor rotates synchronously with the first knob, and the volume adjustment input terminal of the volume adjustment module is in contact with the first ring resistor. And / or, the second adjustment structure 30 is a second knob, and the chain speed adjustment assembly further includes a speed adjustment module. The speed adjustment module is located in the control circuit of the drive device. A second ring resistor is provided at the end of the second knob. The second ring resistor rotates synchronously with the second knob, and the speed adjustment input terminal of the speed adjustment module is in contact with the second ring resistor. In this way, the above configuration can achieve stepless adjustment of the chain speed and pump oil volume, thereby improving the adjustment accuracy.

[0096] In this embodiment, the first adjustment structure 40 is a first knob and the second adjustment structure 30 is a second knob, so that the chainsaw can be infinitely speed-adjusted by the first knob and the pump body 12 can be infinitely volume-adjusted by the second knob.

[0097] Specifically, the first and second ring resistors change synchronously with the rotation of the knob, forming a direct conversion from physical operation to electronic signal. The quantity adjustment module and speed control module, connected to these ring resistors via contact points, can precisely adjust the pump's delivery volume and the drive unit's output power according to the knob position, thereby achieving fine-grained control of the chainsaw's operating status. Simultaneously, the chainsaw employs a combined design of the first knob, the first ring resistor, and the quantity adjustment module, as well as the second knob, the second ring resistor, and the speed control module, achieving precise control and dynamic matching of pump oil volume and chain speed. This improves the equipment's efficiency, safety, and adaptability, while also reducing maintenance costs.

[0098] To achieve the above objectives, the technical solution provided in Embodiment 8 of this utility model is as follows:

[0099] In this embodiment, the chainsaw also includes a third detection device for detecting the load on the chainsaw.

[0100] Specifically, in each speed control mode, the pumping volume of the pump body 12 is controlled according to the detection value of the third detection device. That is, the greater the load of the chainsaw, the more oil is pumped, and the smaller the load of the chainsaw, the less oil is pumped, so as to achieve precise and stepless adjustment of the oil pumping volume of the chainsaw.

[0101] In this embodiment, the pumping oil volume corresponding to the economy mode is (10-8) mL / min, the pumping oil volume corresponding to the normal mode is (12-10) mL / min, and the pumping oil volume corresponding to the enhanced mode is (14-12) mL / min. Specifically, when the chainsaw is in low-speed mode, pressing the first button for the first time adjusts the volume adjustment mode to economy mode, and the pumping oil volume ranges from 8-10 mL / min; when the chainsaw is in medium-speed mode, pressing the first button for the second time adjusts the volume adjustment mode to normal mode, and the pumping oil volume ranges from 10-12 mL / min; when the chainsaw is in high-speed mode, pressing the first button for the third time adjusts the volume adjustment mode to enhanced mode, and the pumping oil volume ranges from 12-14 mL / min.

[0102] To achieve the above objectives, the technical solution provided in Embodiment Nine of this utility model is as follows:

[0103] In this embodiment, the chainsaw also includes a fourth detection device for detecting the trigger press amount of the chainsaw.

[0104] Specifically, in each speed control mode, the pumping volume of the pump body is controlled according to the detection value of the fourth detection device. That is, the greater the trigger press, the more oil is pumped, and the smaller the trigger press, the less oil is pumped, so as to achieve precise and stepless adjustment of the pumping volume. The effective adjustable stroke range of the trigger press is 20%-80%, with the first 20% being the idle stroke and the duty cycle being 100% after 80%.

[0105] In this embodiment, the pumping volume corresponding to the economy mode is (10-8) mL / min, the pumping volume corresponding to the normal mode is (12-10) mL / min, and the pumping volume corresponding to the enhanced mode is (14-12) mL / min. Specifically, the trigger pressing volume range is adjustable. When the trigger pressing volume is between 20-40%, pressing the first button for the first time adjusts the volume adjustment mode to economy mode, and the pumping volume range is 8-10 mL / min; when the trigger pressing volume is between 40-60%, pressing the first button for the second time adjusts the volume adjustment mode to normal mode, and the pumping volume range is 10-12 mL / min; when the trigger pressing volume is between 60-80%, pressing the first button for the third time adjusts the volume adjustment mode to enhanced mode, and the pumping volume range is 12-14 mL / min.

By adding a pump volume adjustment assembly to the chainsaw, with the first adjustment structure electrically connected to the pump body and having multiple adjustment modes, the first adjustment structure corresponding to different delivery volumes of the pump body in different adjustment modes ensures that the lubrication system can provide an appropriate supply of lubricating medium when the chainsaw cuts different materials (such as dry wood, wet wood, ice, hard plastic, etc.), avoiding problems of insufficient or excessive lubrication, effectively extending the service life of the cutting assembly and the performance of the chain, and thus solving the problem in the prior art where the pump volume of the lubrication system is difficult to adjust according to actual needs. In this way, the multiple adjustment modes of the first adjustment structure provide users with more flexible operating options, allowing them to adjust the pump oil volume at any time according to actual needs, which not only improves the cutting efficiency of the chainsaw but also enhances the user experience for operators.
