Description

Technical Field

[0001] This application relates to the field of tool and equipment technology, specifically to an electric planer. Background Technology

[0002] Currently, electric planers often shut down directly when they experience stalling or overcurrent protection issues. However, since the planer was planing wood or other target materials before stopping, the cutter shaft can easily get stuck with debris. If the cutter shaft rotates in one direction, the debris can completely jam it. In this case, a tool must be used to reverse the rotation of the cutter shaft to remove the debris, which is cumbersome, inefficient, and prone to safety issues, negatively impacting the user experience.

[0003] This section provides background information related to this application, which is not necessarily prior art. Summary of the Invention

[0004] One object of this application is to solve or at least alleviate some or all of the aforementioned problems. Therefore, one object of this application is to provide an electric planer.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides an electric planer, comprising:

[0029] A controller is used to control the operating status of a motor.

[0030] The mode selection component, located on the housing, is used to output mode setting commands to the controller when operated.

[0031] The controller is configured as follows:

[0032] In response to the mode setting command, the operating mode of the electric planer is set, and the operating mode includes at least one chip removal mode;

[0033] When the electric planer is in chip removal mode and the preset trigger conditions are met, the electric planer is controlled to perform the preset chip removal process.

[0034] In some embodiments, the electric planer further includes a mode indicator component; the mode indicator component is disposed on the housing and is used to indicate whether the electric planer is in chip removal mode.

[0035] In some embodiments, the operating mode includes n chip removal modes, and the mode selection component includes at least n mode selection buttons, each mode selection button corresponding to a different chip removal mode.

[0036] In some embodiments, the electric planer further includes a mode indicator assembly, which includes a plurality of mode indicator units disposed on the housing;

[0037] The multiple mode indicator units are used to indicate whether the electric planer is in the chip removal mode corresponding to the mode indicator unit.

[0038] In some embodiments, the operating modes include at least an automatic chip removal mode and an active chip removal mode.

[0039] In some embodiments, the controller is configured to:

[0040] When the electric planer changes from working state to stop state, determine whether the current operating mode is automatic chip removal mode;

[0041] If the current operating mode is automatic chip removal mode, the control motor drives the cutter shaft to rotate in the first direction; the first direction is the opposite direction of the cutter shaft rotation in the working state.

[0042] In some embodiments, the controller is configured to: when the electric planer enters a stopped state from the working state due to stall or overcurrent, determine whether the current operating mode is the first automatic chip removal mode;

[0043] If the current operating mode is the first automatic chip removal mode, then control the motor to drive the cutter shaft to rotate in the first direction.

[0044] In some embodiments, the controller is configured to:

[0045] When the electric planer responds to the stop command and enters the stop state from the working state, it determines whether the current operating mode is the second automatic chip removal mode.

[0046] If the current operating mode is the second automatic chip removal mode, then control the motor to drive the cutter shaft to rotate in the first direction.

[0047] In some embodiments, the control is further configured to:

[0048] When the electric planer enters the working state from the stopped state, determine whether the current operating mode is active chip removal mode.

[0049] If the current operating mode is active chip removal mode, then control the motor to drive the cutter shaft to rotate in the first direction.

[0050] Thirdly, this application also provides an electric planer, comprising:

[0051] case

[0052] A cutter shaft is disposed within a housing; the cutter shaft includes at least one planing section, the planing section including a planing blade and a planing groove;

[0053] The motor is used to drive the cutter shaft to rotate;

[0054] A controller is used to control the operating status of a motor.

[0055] The controller is configured as follows:

[0056] When the electric planer changes from working state to stop state, determine whether the electric planer is in chip removal operation mode;

[0057] If the electric planer is in chip removal mode, the control motor drives the cutter shaft to rotate at least a first angle in a first direction; wherein, the first direction is the opposite direction of the cutter shaft rotation in the working state, and the first angle is related to the curvature of the planing groove relative to the axis of the cutter shaft.

[0058] In some embodiments, the first angle is greater than or equal to the arc of the groove relative to the axis of the cutter shaft.

[0059] In some embodiments, the rotational speed of the cutter shaft when it rotates in a first direction is a first rotational speed; the first rotational speed is less than the rotational speed of the cutter shaft in the working state.

[0060] In some embodiments, the cutter shaft includes a plurality of planing sections, and along a first direction, the total arc of the cutter shaft axis relative to the planing groove of the first planing section to the planing groove of the last planing section is a first arc; the first angle is greater than or equal to the first arc.

[0061] In some embodiments, the controller is further configured to:

[0062] If the chip removal function is enabled in the operating mode, the control motor drives the cutter shaft to rotate intermittently multiple times in the first direction, and each rotation is at least the first angle.

[0063] In some embodiments, the number of times the cutter shaft rotates in the first direction is positively correlated with the continuous working time of the electric planer before it enters the stop state.

[0064] The advantages of this application are as follows: by driving the cutter shaft to rotate via the electric planer motor, the controller controls the motor's operating state. The controller is configured to determine whether the electric planer is in chip removal mode when it transitions from working to stopped state. When the electric planer is in chip removal mode, the controller controls the motor to drive the cutter shaft to rotate in the opposite direction to the cutting shaft rotation direction in working state. This allows the electric planer to automatically remove chips, reducing the possibility of the cutter shaft being jammed by waste chips. At the same time, it can alleviate the problem of a large amount of foreign matter and waste chips accumulating inside the electric planer when it stops, which makes it difficult to replace the cutter shaft. Thus, it helps to improve the working efficiency of the electric planer and the user experience. Attached Figure Description

For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0083] Figure 1 This is a perspective view of the electric planer provided in the embodiments of this application. Figure 2 This is a perspective view of the bottom of the electric planer provided in an embodiment of this application. Figure 3 This is a schematic diagram of the cutter shaft provided in an embodiment of this application. Figure 4 This is a diagram of the electrical control module of an electric planer provided in an embodiment of this application. (Refer to the reference...) Figures 1 to 4 As shown, the electric planer provided in this embodiment includes: a housing 1, a cutter shaft 3, a motor 2, and a controller 5. The cutter shaft 3 is disposed inside the housing 1 and includes at least one planing section 31. Each planing section 31 includes a planing blade 31a and a planing groove 31b. The planing blade 31a is used to plan wood or other target materials by being driven by the rotation of the cutter shaft 3 when the electric planer is working. The planing groove 31b is used to temporarily store and discharge planing waste. It is understood that when the electric planer is stopped from the working state, some waste may be located between the planing groove 31b and the planing blade 31a, which may prevent the waste from being discharged in time, thus preventing the cutter shaft 3 from continuing to rotate and causing the cutter shaft 3 to be jammed by the waste.

[0084] Motor 2 is used to drive the cutter shaft 3 to rotate in order to achieve the planing function.

[0085] Controller 5 is connected to the motor 2 and is used to control the operating state of motor 2. Controlling the operating state of motor 2 includes at least controlling its direction of rotation and / or speed. Furthermore, controller 5 can acquire the motor's operating parameters, including at least the motor's operating mode, speed and / or current, and operating time. The motor's operating mode includes at least one chip removal mode.

[0086] In this embodiment, the controller 5 is configured to: when the electric planer enters the stop state from the working state, determine whether the electric planer is in the chip removal mode; if the electric planer is in the chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in the first direction.

[0087] The working state of the electric planer can be understood as the state in which the controller 5 controls the motor 2 to rotate at a certain speed or power according to the user's input instructions. The stopped state of the electric planer can be understood as the state in which the motor 2 stops rotating. The transition of the electric planer from the working state to the stopped state refers to the process of the motor 2 stopping rotating.

[0088] Chip removal mode can be understood as the operating mode in which the chip removal function is activated. It is understood that an electric planer can be equipped with at least one operating mode in which the chip removal function is activated. The operating mode in which the chip removal function is activated is the operating mode that performs chip removal processing under certain conditions. In some embodiments, the chip removal mode includes, but is not limited to, at least one automatic chip removal mode and at least one active chip removal mode. The automatic chip removal mode is the operating mode in which chip removal processing is performed when the electric planer transitions from a working state to a stopped state, and the active chip removal mode is the operating mode in which chip removal processing is performed when the electric planer transitions from a stopped state to a working state. In some embodiments, the chip removal mode can be built into the controller 5 of the electric planer. In some embodiments, the chip removal mode can be set by user operation.

[0089] The first direction is opposite to the rotation direction of the cutter shaft 3 in the working state. For example, if the electric planer rotates clockwise in the working state to plan the target material, the first direction is counterclockwise. Conversely, if the electric planer rotates counterclockwise in the working state, the first direction is clockwise, so that waste chips can be discharged.

[0090] It is understood that when the control motor 2 drives the cutter shaft 3 to rotate in the first direction, it needs to rotate at least until the waste chips are completely discharged. In some embodiments, the controller 5 is configured to: if the electric planer is in chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in the first direction for a preset time and / or a preset angle.

[0091] The preset duration and preset angle can be customized by the user according to their needs, or preset based on the parameters of the cutter shaft 3. Specifically, the preset duration can be set so that the motor 2 drives the cutter shaft 3 to rotate at least 360° within the preset duration. Similarly, the preset angle should be greater than the angle corresponding to the total arc of the cutter shaft 3 axis relative to the groove 31b of the cutter shaft 3. This ensures that after the electric planer enters a stopped state, the angle of rotation of the cutter shaft in the first direction is at least greater than the angle required to expose all the grooves of the cutter shaft, thus guaranteeing that at least the waste chips inside the grooves of each cutter shaft have a chance to be discharged, rather than being constantly retained between the housing and the cutter shaft. Controlling the motor 2 to drive the cutter shaft 3 to rotate in the first direction for a preset duration and / or a preset angle can be understood as controlling the motor 2 to drive the cutter shaft 3 to rotate in the first direction for a preset duration, or controlling the motor 2 to drive the cutter shaft 3 to rotate in the first direction for a preset angle, or controlling the motor 2 to drive the cutter shaft 3 to rotate in the first direction for a preset duration within a preset angle. When the control motor 2 drives the cutter shaft 3 to rotate a preset angle in the first direction within a preset time, it actually limits the speed at which the motor 2 drives the cutter shaft 3 to rotate in the first direction.

[0092] In this embodiment, by driving the cutter shaft to rotate via the electric planer motor, the controller controls the motor's operating state. The controller is configured to determine whether the electric planer is in chip removal mode when it transitions from a working state to a stopped state. When the electric planer is in chip removal mode, the controller controls the motor to drive the cutter shaft to rotate in a first direction opposite to the rotation direction of the cutter shaft in the working state. This allows the electric planer to automatically remove chips, reducing the possibility of the cutter shaft being jammed by foreign objects. At the same time, it can alleviate the problem of a large amount of waste chips accumulating inside the electric planer when it stops, which makes it difficult to replace the cutter shaft. Thus, it is beneficial to improve the working efficiency of the electric planer and the user experience.

[0093] In some embodiments, when a stall or overcurrent is detected in the electric planer, the electric planer enters a stop state from the working state. At this time, the motor 2 can be controlled to drive the cutter shaft 3 to rotate in a first direction so that the electric planer can automatically remove waste chips. In some embodiments, in response to a stop command from the electric planer, the electric planer enters a stop state from the working state. At this time, the motor 2 can be controlled to drive the cutter shaft 3 to rotate in a first direction so that the electric planer can automatically remove waste chips.

[0094] In one scenario, the user actively controls the electric planer to switch from working to stopped mode. At this time, the planer's cutter shaft reverses, which facilitates the timely removal of debris from the planer groove. In another scenario, the electric planer switches from working to stopped mode due to blockage by debris or foreign objects. The reverse rotation of the planer's cutter shaft helps to expel debris and foreign objects from the planer groove, alleviating the blockage problem.

[0095] In some embodiments, the controller 5 is configured to: if the electric planer is in chip removal mode and the continuous working time of the electric planer before entering the stop state is greater than a first time, control the motor 2 to drive the cutter shaft 3 to rotate in a first direction.

[0096] The first duration can be built into the controller 5 of the electric planer. The first duration is greater than or equal to 0. In some embodiments, the first duration can be 0 minutes, that is, when the electric planer is in chip removal mode, there is no limit to the continuous working time of the electric planer before entering the stop state. As long as it enters the stop state from the working state, the control motor 2 drives the cutter shaft 3 to rotate in the first direction to remove waste chips, thereby minimizing the possibility of chip clogging. In some embodiments, the first duration can be 4 minutes, that is, when the electric planer is in chip removal mode, the continuous working time of the electric planer before entering the stop state is greater than 4 minutes before the control motor 2 drives the cutter shaft 3 to rotate in the first direction. Otherwise, the control motor 2 stops directly, thereby reducing energy consumption while effectively preventing chip clogging of the electric planer.

[0097] It is understandable that the greater the load on the electric planer, the more chips it produces, making it more prone to chip clogging. Therefore, in some embodiments, the controller 5 is configured to: if the electric planer is in chip removal mode and the cumulative high-load working time before entering the stop state is greater than a second duration, then control the motor 2 to drive the cutter shaft 3 to rotate in a first direction.

[0098] The second duration can also be built into the controller 5 of the electric planer. The second duration can be the same as or different from the first duration; this embodiment does not specifically limit this. In some embodiments, the second duration is 4 minutes. The high-load operating duration can be the duration during which the bus current of the electric planer exceeds a first current threshold while it is in operation. The first current threshold can be set according to the actual parameters of the electric planer. In some embodiments, the first current threshold can be 30A. Of course, other load parameters of the electric planer can also be used to determine the high load; this embodiment does not limit this.

[0099] Specifically, when the electric planer is in chip removal mode, if the cumulative high-load working time before the electric planer enters the stop state is greater than the second duration, it indicates that the electric planer is likely to have generated a large amount of waste chips. When the motor 2 restarts after stopping, chip blockage is likely to occur. At this time, the motor 2 can be controlled to drive the cutter shaft 3 to rotate in the first direction to perform chip removal when the electric planer enters the stop state, thereby reducing the degree of chip blockage and preventing a large amount of waste chips from remaining inside the electric planer when it stops, which would affect the subsequent use of the electric planer.

[0100] In some embodiments, the controller 5 is further configured to: when the electric planer enters the working state from the stopped state, determine whether the current operating mode of the electric planer is the active chip removal mode; if the electric planer is in the active chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in the first direction.

[0101] The transition of the electric planer from a stopped state to a working state can be understood as the controller 5 responding to the user's work command to control the motor 2 to operate. The user's work command can be, but is not limited to, controlling the electric planer to start working, for example, the user pressing the work switch.

[0102] Specifically, when the electric planer enters the working state from the stopped state, that is, when the controller 5 responds to the user's work command to control the motor 2 to run, it first determines whether the current operating mode of the electric planer is the active chip removal mode. When the electric planer is in the active chip removal mode, it controls the motor 2 to drive the cutter shaft 3 to rotate in the first direction to discharge the waste chips. This reduces the possibility that the electric planer will directly enter the working mode and be jammed by the waste chips when a large amount of waste chips are stuck in the gap of the cutter shaft 3, thereby further improving the user experience.

[0103] Figure 5 This is a control flowchart of an electric planer provided as an embodiment of this application. Specifically, refer to... Figure 5 As shown in the embodiments of this application, the control flow of the electric planer is as follows:

[0104] S110. When the electric planer enters the stop state from the working state, determine whether the electric planer is in the chip removal mode. If so, execute S120, S130 or S140.

[0105] In one alternative embodiment, when a stall or overcurrent is detected in the electric planer, the electric planer is controlled to switch from the working state to the stopped state; or, in response to a stop command from the electric planer, the electric planer is controlled to switch from the working state to the stopped state.

[0106] S120. If the electric planer is in chip removal mode and the continuous working time of the electric planer before entering the stop state is greater than the first duration, then control the motor to drive the cutter shaft to rotate in the first direction.

[0107] S130. If the electric planer is in chip removal mode and the cumulative high-load working time of the electric planer before entering the stop state is greater than the second duration, then control the motor to drive the cutter shaft to rotate in the first direction.

[0108] The high-load working time is the duration during which the bus current of the electric planer is greater than the first current threshold when it is in operation.

[0109] S140. If the electric planer is in active chip removal mode, the control motor drives the cutter shaft to rotate in the first direction.

[0110] The first direction is opposite to the direction of the tool axis rotation in the working state.

[0111] In one optional embodiment, when the control motor drives the cutter shaft to rotate in a first direction, the control motor drives the cutter shaft to rotate in the first direction for a preset duration and / or a preset angle.

[0112] Based on the same concept, this application also provides an electric planer. Figure 6 This is a diagram of the electrical control module of another electric planer provided in an embodiment of this application. (Continue to refer to...) Figures 1 to 3 ,as well as Figure 6 As shown, based on the above embodiment, the electric planer further includes a mode selection component 4, which is disposed on the housing. The controller 5 is connected to the mode selection component 4, and the mode selection component 4 is used to output mode setting commands to the controller 5 when operated. The mode setting component 4 includes at least one mode selection button 41, and the mode setting commands include, but are not limited to, an activation command for at least one chip removal mode.

[0113] In this embodiment, the controller 5 is configured to: in response to the mode setting command, set the operating mode of the electric planer; when the electric planer is in the chip removal mode and the preset triggering conditions are met, control the electric planer to perform preset chip removal processing.

[0114] The operating mode includes at least one chip removal mode. A chip removal mode can be understood as an operating mode that performs chip removal processing under certain conditions. A preset trigger condition can be understood as the trigger condition for the corresponding chip removal mode. In some embodiments, when the chip removal mode is automatic chip removal mode, the preset trigger condition is that the electric planer enters a stopped state from a working state. In some embodiments, when the chip removal mode is automatic chip removal mode, the preset trigger condition is that the electric planer enters a stopped state from a working state, and the continuous working time of the electric planer before entering the stopped state is greater than a first duration. In some embodiments, the preset trigger condition is that the electric planer enters a working state from a stopped state. The preset chip removal processing can be understood as the chip removal processing method corresponding to the corresponding chip removal mode. In some embodiments, the preset chip removal processing is controlling the motor 2 to drive the cutter shaft 3 to rotate in a first direction.

[0115] Specifically, the electric planer housing is equipped with a mode selection component 4, which the user can operate to output a mode setting command to the controller 5. The controller 5 then responds to this command, setting the electric planer's operating mode. When the electric planer is in chip removal mode and a preset trigger condition is met, the controller 5 controls the electric planer to perform a preset chip removal process, enabling the electric planer to perform chip removal under certain conditions, thereby reducing the possibility of the electric planer getting stuck in chips.

[0116] In some embodiments, the electric planer also includes a mode indicator component disposed on the housing, which is used to indicate whether the electric planer is in chip removal mode, so that the user can obtain the current operating mode of the electric planer in real time through the mode indicator component, so as to know in advance whether the electric planer will perform preset chip removal processing when the preset trigger conditions are met, thereby further improving the user experience.

[0117] The mode indicator component may include, but is not limited to, at least one indicator light, which indicates whether the electric planer is in chip removal mode and / or what chip removal mode the electric planer is in by illuminating the corresponding indicator light or by illuminating the indicator light with different colors.

[0118] In this embodiment, the operating mode of the electric planer is set by making the controller 5 respond to the mode setting command output when the mode selection component is operated. The operating mode includes at least one chip removal mode. When the electric planer is in the chip removal mode and the preset triggering conditions are met, the electric planer is controlled to perform preset chip removal processing. This allows the user to set the timing of the electric planer's chip removal processing, increases the interactivity of the electric planer, and thus helps to improve the user experience.

[0119] Understandably, mode selection button 41 can be set to one or more modes.

[0120] In some embodiments, when the electric planer is equipped with a mode selection button 41, the mode selection button 41 can output one or more mode setting commands. For example, when the electric planer's operating modes include n chip removal modes, each press of the mode selection button 41 outputs a mode setting command for the next chip removal mode, thereby causing the controller 5 to switch and set the corresponding operating mode. When the mode selection button 41 is pressed for the nth time, the nth mode setting command is output. Furthermore, it can be set that when the mode selection button 41 is pressed for the (n+1)th time, the same mode setting command is output as when the mode selection button 41 is pressed for the first time.

[0121] In some embodiments, when the electric planer is equipped with multiple mode selection buttons 41, for example, the operating mode includes n chip removal modes, the mode selection component 4 includes at least n mode selection buttons 41, each mode selection button 41 corresponding to a different chip removal mode. This allows the user to set the corresponding operating mode by simply pressing the corresponding mode selection button 41 when setting different chip removal modes, thereby making the mode selection more intuitive, improving the ease of operation, and further enhancing the user experience.

[0122] In some embodiments, the electric planer provided in this embodiment can also communicate with a terminal device via a network, so that the terminal device can perform corresponding operations to output mode setting instructions to the controller 5, making the operation of the electric planer more flexible and thus further improving the user experience.

[0123] The terminal device may include, but is not limited to, mobile phones, computers, or terminal remote controls. The network may include, but is not limited to, wired or wireless networks; this embodiment does not impose specific limitations on this, as long as it enables communication between the electric planer and the terminal device.

[0124] In some embodiments, when the electric planer includes n chip removal modes, the mode indicator component includes multiple mode indicator units disposed on the housing, and the multiple mode indicator units are respectively used to indicate whether the electric planer is in the chip removal mode corresponding to the mode indicator unit.

[0125] The mode indicator unit may include, but is not limited to, indicator lights. Each mode indicator unit corresponds one-to-one with a mode selection button 41, allowing each mode indicator unit to individually indicate its corresponding chip removal mode. By including multiple mode indicator units in the electric planer, and having each mode indicator unit indicate whether the electric planer is in its corresponding chip removal mode, users can more easily understand the current operating mode of the electric planer, i.e., which chip removal mode it is in, thereby further improving the user experience.

[0126] In some embodiments, the chip removal mode includes, but is not limited to, automatic chip removal mode and active chip removal mode.

[0127] The automatic chip removal mode can be understood as the operating mode that performs chip removal when the electric planer transitions from a working state to a stopped state. The active chip removal mode can be understood as the operating mode that performs chip removal when the electric planer transitions from a stopped state to a working state. By including both automatic and active chip removal modes, users can select the appropriate mode according to their actual needs, thereby further improving operational convenience and enhancing the user experience.

[0128] In some embodiments, the controller 5 is configured to: when the electric planer enters a stopped state from a working state, determine whether the current operating mode is an automatic chip removal mode; if the current operating mode is an automatic chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in a first direction. The first direction is the opposite direction to the rotation direction of the cutter shaft 3 in the working state.

[0129] Specifically, when the electric planer enters the stop state from the working state, it is determined whether the current operating mode is the automatic chip removal mode. If the current operating mode is the automatic chip removal mode, the electric planer performs chip removal processing, that is, it controls the motor 2 to drive the cutter shaft 3 to rotate in the first direction to discharge the waste chips.

[0130] In this embodiment, the automatic chip removal mode includes a first automatic chip removal mode and a second automatic chip removal mode.

[0131] In some embodiments, the controller 5 is further configured to: when the electric planer enters a stopped state from the working state due to stall or overcurrent, determine whether the current operating mode is the first automatic chip removal mode; if the current operating mode is the first automatic chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in the first direction.

[0132] In some embodiments, the controller 5 is configured to: when the electric planer responds to the stop command of the electric planer and enters the stop state from the working state, determine whether the current operating mode is the second automatic chip removal mode; if the current operating mode is the second automatic chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in the first direction.

[0133] The first automatic chip removal mode can be understood as the operating mode that performs chip removal when the electric planer stops due to stalling or overcurrent. The second chip removal mode can be understood as the operating mode that performs chip removal when the machine stops due to a user-input stop command. The duration or angle for which the control motor 2 drives the cutter shaft 3 to rotate in the first direction can be set according to actual needs. In the first and second automatic chip removal modes, the duration or angle for which the control motor 2 drives the cutter shaft 3 to rotate in the first direction can be different or the same. This embodiment does not impose specific limitations on this, as long as it achieves the core inventive point of this application.

[0134] In some embodiments, the controller 5 is further configured to: when the electric planer enters the working state from the stopped state, determine whether the current operating mode is the active chip removal mode; if the current operating mode is the active chip removal mode, control the motor 2 to drive the cutter shaft 3 to rotate in the first direction.

[0135] Specifically, when the electric planer enters the working state from the stopped state, it determines whether the current operating mode is active chip removal mode. If the current operating mode is active chip removal mode, the electric planer performs chip removal processing, that is, it controls the motor 2 to drive the cutter shaft 3 to rotate in the first direction to discharge the waste chips. This reduces the possibility that the electric planer will be jammed by waste chips when a large amount of waste chips get stuck in the gap of the cutter shaft 3 and directly enter the working mode, thereby further improving the user experience.

[0136] Figure 7 This is a control flowchart for another electric planer provided in an embodiment of this application. Specifically, refer to... Figure 7As shown in the embodiments of this application, the control flow of the electric planer is as follows:

[0137] S210. In response to the mode setting command output by the mode selection component, the operating mode of the electric planer is set.

[0138] Among them, the operating mode includes at least one chip removal mode.

[0139] In one optional embodiment, the operating modes include at least an automatic chip removal mode and an active chip removal mode.

[0140] S220. When the electric planer is in chip removal mode and the preset triggering conditions are met, control the electric planer to perform the preset chip removal process.

[0141] In an alternative embodiment, Figure 8 A control flowchart for another electric planer provided in this application embodiment is shown below. Figure 8 As shown, the control flow of the electric planer provided in this application embodiment specifically includes:

[0142] S210. In response to the mode setting command output by the mode selection component, the operating mode of the electric planer is set.

[0143] Among them, the operating mode includes at least one chip removal mode.

[0144] S221. When the electric planer enters the stop state from the working state, if the current operating mode is the first automatic chip removal mode, the motor is controlled to drive the cutter shaft to rotate in the first direction.

[0145] S222. If the current operating mode is the second automatic chip removal mode, then control the motor to drive the cutter shaft to rotate in the first direction.

[0146] S223. If the current operating mode is active chip removal mode, then control the motor to drive the cutter shaft to rotate in the first direction.

[0147] The first direction is the opposite direction to the rotation direction of the tool axis during operation.

[0148] Based on the same concept, this embodiment also provides an electric planer, which can be referenced further. Figures 1 to 4 As shown, the cutter shaft 3 of the electric planer includes at least one planing part 31, which includes a planing blade 31a and a planing groove 31b.

[0149] The cutter shaft 3 includes at least one planing part 31, which can be understood as the cutter shaft 3 including one or more planing parts 31. Figure 3The illustration only shows the case where the cutter shaft 3 includes two planing sections 31, and does not limit the number of planing sections 31 of the cutter shaft 3. Each planing section 31 includes a planing blade 31a and a planing groove 31b. The planing blade 31a is used to plan the target material such as wood when the electric planer is working, and the planing groove 31b is used to temporarily store and discharge planing waste.

[0150] In this embodiment, the controller 5 is configured to: when the electric planer enters the stop state from the working state, determine whether the electric planer is in the chip removal operation mode; if the electric planer is in the chip removal operation mode, control the motor 2 to drive the cutter shaft 3 to rotate at least a first angle in the first direction.

[0151] The first direction is the opposite direction to the rotation direction of the cutter shaft 3 in the working state, and the first angle is related to the curvature of the groove 31b relative to the axis of the cutter shaft 3. The curvature of the groove 31b relative to the axis of the cutter shaft 3 can be understood as the curvature occupied by the opening of the groove 31b on the outer circumference of the cutter shaft.

[0152] In some embodiments, the first angle is greater than or equal to the arc of the groove 31b relative to the axis of the cutter shaft 3.

[0153] It is understandable that when an electric planer enters a stopped state due to chip blockage, the cutter shaft is often rotated to a state where a certain groove is not exposed, and the planer's stoppage is most likely caused by chips in that groove. Therefore, by making the first angle greater than or equal to the arc of the groove 31b relative to the axis of the cutter shaft 3, the chips in the groove 31b can be discharged.

[0154] In some embodiments, when the cutter shaft 3 includes multiple planing sections 31, the total arc of the axis of the cutter shaft 3 relative to the planing groove 31b of the first planing section 31 to the planing groove 31b of the last planing section 31 along the first direction is a first arc, and the first angle is greater than or equal to the first arc. This ensures that when the control motor 2 drives the cutter shaft 3 to rotate by a first angle in the first direction, all planing grooves 31b in the cutter shaft 3 are exposed at least once. In this way, it can be guaranteed that each planing groove 31b in the cutter shaft 3 has the opportunity to discharge waste chips.

[0155] In some embodiments, the rotational speed of the cutter shaft 3 when rotating in the first direction is a first rotational speed, which is less than the rotational speed of the cutter shaft 3 in the working state. By reducing the rotational speed of the cutter shaft 3 when rotating in the first direction, i.e. the rotational speed during chip removal, on the one hand, a lower rotational speed is used to ensure that each planing groove is exposed for a longer time each time, increasing the time available for chip removal and making it easier to remove waste chips. On the other hand, when the cutter shaft removes chips at a lower rotational speed, the circumferential momentum of the discharged waste chips can be reduced, reducing the amplitude of the waste chips scattered, which facilitates subsequent cleaning of waste chips. Furthermore, when the electric planer removes chips, it is generally far away from the workpiece, and the cutter shaft is in a suspended state. Removing chips at a lower rotational speed can ensure the safety of the electric planer during chip removal, and at the same time, it can save energy consumption during chip removal to a certain extent.

[0156] In some embodiments, the controller 5 is further configured to: if in the operation mode with chip removal function enabled, control the motor 2 to drive the cutter shaft 3 to rotate intermittently multiple times in a first direction, and each rotation is at least a first angle.

[0157] Intermittently rotating multiple times in the first direction can be understood as having a certain time interval between each two rotations in the first direction. By controlling the electric planer to drive the cutter shaft 3 to rotate intermittently multiple times in the first direction during chip removal, and rotating at least a first angle each time, the amount of residual chips in the planer groove 31b after chip removal can be reduced. This further prevents chips from being hidden inside the electric planer when it stops, which is beneficial to further improving the user experience.

[0158] It should be noted that the longer the electric planer operates continuously, the more debris it produces, resulting in more debris remaining in the planing groove 31b, making it more difficult to remove the debris. Therefore, in some embodiments, the number of times the cutter shaft 3 rotates in the first direction is positively correlated with the continuous operating time of the electric planer before it enters the stop state.

[0159] The number of times the cutter shaft 3 rotates in the first direction is positively correlated with the continuous working time of the electric planer before it enters the stop state. This can be understood as the longer the continuous working time of the electric planer before it enters the stop state, the more times the cutter shaft 3 rotates in the first direction, and the stronger the ability to remove waste chips. Conversely, the shorter the continuous working time of the electric planer before it enters the stop state, the fewer times the cutter shaft 3 rotates in the first direction, and the weaker the ability to remove waste chips.

[0160] Specifically, by making the cutter shaft 3 rotate in the first direction a number of times, which is positively correlated with the continuous working time of the electric planer before it enters the stop state, the cutter shaft 3 can be rotated more times in the first direction when there are more and more chips in the planer groove 31b and they are more difficult to remove, thereby improving the chip removal capacity and further preventing chips from remaining in the electric planer when it stops. Conversely, when there are fewer chips in the planer groove 31b, the cutter shaft 3 can be rotated less times in the first direction, thereby reducing the energy and time consumed in chip removal and improving chip removal efficiency.

[0161] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
