Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0030] The singular forms “a” and “the” used in this specification and the appended claims include plural references unless otherwise expressly stated herein. It should be noted that the term “or” is generally used to include the meaning of “or / and” unless otherwise expressly stated herein.

[0031] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0032] The first embodiment of this invention relates to a portable electric cutting tool, which can perform cutting operations via shears mounted on it, such as electric pruning shears. Figure 1 As shown, the portable electric knife includes: a control module 10, and a first triggering device 11, a second triggering device 12, and a scissor assembly, all of which are communicatively connected to the control module 10. The first triggering device 11 and the second triggering device 12 are both operable buttons mounted on the outer casing of the portable electric knife.

[0033] In addition, the portable electric cutting tool also includes a power module 14 and a power switch 15. The power module 14 is electrically connected to the control module 10, and the power switch 15 is communicatively connected to the control module 10. The power module 14 is used to supply power to the various modules in the portable electric cutting tool so that the portable electric cutting tool can work normally. It can be a battery pack that is detachably mounted on the portable electric cutting tool. The control module 10 can control the power supply of the portable electric cutting tool to turn on or off according to the detected on or off state of the power switch 15. The power switch 15 can be a push-button switch.

[0034] The scissor assembly includes a drive module 131, a moving blade 132, and a fixed blade 133. The drive module 131 is communicatively connected to the control module 10, and the drive module 131 is mechanically connected to the moving blade 132 (not shown in the figure). The fixed blade 133 is fixed on the housing of the portable electric knife, and the moving blade 132 is fixed on the housing of the portable electric knife and can rotate around the pivot.

[0035] The drive module 131 is used to drive the moving blade 132 to open and close relative to the fixed blade 133. That is, the drive module 131 can drive the moving blade 132 to rotate around the rotating shaft and move toward the fixed blade 133 to perform shearing activities.

[0036] The first triggering device 11 is used to receive operation signals and send them to the control module 10. The operation signals are used to control the operation of the scissor assembly. Specifically, the first triggering device 11 can receive user operations, generate operation signals and send them to the control module 10. The control module 10 controls the scissor assembly to perform cutting activities based on the operation signals. That is, the control module 10 controls the drive module 131 to drive the moving blade 132 to rotate around the rotating shaft and move towards the fixed blade 133 to perform cutting activities.

[0037] The second triggering device 12 is used to receive the trigger signal and send it to the control module 10. In one example, the second triggering device 12 can be a triggering device on a portable electric tool that is dedicated to triggering the portable electric tool to a preset function mode, that is, the second triggering device 12 does not perform work control on the portable electric tool.

[0038] In another example, the second triggering device 12 can be another triggering device in the portable electric tool besides the first triggering device 11. That is, the triggering signal of the second triggering device 12 is used to control the portable electric tool to perform the function corresponding to the second triggering device. When the second triggering device 12 is triggered alone, it can be used to control the operation of the portable electric tool.

[0039] Specifically, the duration for which the second triggering device is triggered to control the portable electric tool to perform the function corresponding to the second triggering device can be set to differ from the duration for which the second triggering device is triggered in a preset signal combination. This distinguishes between the triggering of the second triggering device's own function and the triggering of the preset function corresponding to the preset signal combination, enabling independent triggering of the two functions and avoiding mutual interference. For example, if the duration for which the second triggering device is triggered to control the portable electric tool to perform the function corresponding to the second triggering device is set to be longer than the duration for which the second triggering device is triggered in the preset signal combination, then when the function corresponding to the preset signal combination is triggered, the function corresponding to the second triggering device will not be triggered.

[0040] In this embodiment, the control module 10 is used to execute a preset function corresponding to the preset signal combination when the combination of the received operation signal and trigger signal matches the preset signal combination.

[0041] Specifically, the control module 10 can be a processing unit with computing capabilities, such as a controller or a microprocessor. The control module 10 is configured with at least one preset signal combination, and each preset signal combination corresponds to a preset function. When multiple preset signal combinations are set, each preset signal combination can be configured to correspond to a different preset function, thereby enabling the triggering of multiple preset function modes. However, it is not limited to this; each preset function can also be configured to correspond to multiple preset signal combinations, that is, the same preset function can be triggered through multiple preset signal combinations.

[0042] The preset functions include any one or any combination of the following: controlling the portable electric knife to enter the working state, controlling the portable electric knife to enter the sleep state, controlling the portable electric knife to enter the power-off state, and adjusting the blade angle α of the scissor assembly (i.e., adjusting...). Figure 1 When the scissor assembly is not in operation, the blade angle α is...

[0043] In this embodiment, the triggering method of the first triggering device 11 and the second triggering device 12 refers to the process from when the triggering device (the first triggering device and the second triggering device) is triggered until it is no longer triggered. Common triggering methods include, but are not limited to: a short single press, a short double press, a long single press, and a long double press. A short press indicates a press lasting less than 2 seconds, preferably less than 1 second. A long press indicates a press lasting longer than 2 seconds. A single press indicates that the same triggering device is triggered only once (either a short press or a long press), meaning that two adjacent presses are triggered by different triggering devices. A double press indicates that the same triggering device is triggered multiple times consecutively (either a short press or a long press).

[0044] For the received combination of operation signal and trigger signal, control module 10 compares the current combination with a preset signal combination to determine whether to execute the preset function. Control module 10 sets different comparison methods based on different preset signal combinations.

[0045] In one example, the preset signal combination includes: an operation signal and a trigger signal being triggered simultaneously. That is, the control module 10 detects that the first trigger device and the second trigger device are triggered simultaneously. For example, while detecting the second trigger device being triggered (e.g., a long press or a short press), it also detects that the first trigger device is triggered. Specifically, it can be that while detecting the second trigger device being short-pressed, it detects that the first trigger device is clicked. When the control module 10 receives the operation signal and the trigger signal simultaneously, it executes the preset function corresponding to the preset signal combination and enters the preset function mode.

[0046] In another example, the preset signal combination includes: receiving an operation signal obtained by triggering the first triggering device in a first manner and a trigger signal obtained by triggering the second triggering device in a second manner, respectively. The first manner and the second manner can be the same or different; specifically, they can be divided into the following two types:

[0047] In the first scenario, while the first triggering device is being triggered in the first manner, the second triggering device is being triggered in the second manner. For example, when the first triggering device is detected to be pressed for a long time, the second triggering device is detected to be pressed for a short time or for a long time, or when the second triggering device is detected to be pressed for a long time, the first triggering device is clicked or double-clicked.

[0048] The second type is that after the first triggering device is triggered in the first manner, the second triggering device is triggered in the second manner; for example, after the first triggering device is detected to be clicked or double-clicked, the second triggering device is detected to be long-pressed or short-pressed.

[0049] The control module 10 compares the current combination with the preset signal combination in two ways:

[0050] Method 1: When there is no restriction on the order of operation signal and trigger signal in the preset signal combination, taking the control module 10 first detecting that the first touch device is triggered to receive the operation signal as an example, if the triggering method of the received operation signal is different from the preset triggering method of the operation signal in each preset signal combination, the preset function mode will not be entered, and the control module 10 will only control the scissors assembly to perform cutting activities based on the operation signal.

[0051] If the triggering mode of the received operation signal is the same as the preset triggering mode of the operation signal in one or more preset signal combinations, the control module 10 marks these one or more preset signal combinations. After detecting that the second triggering device has been triggered and received a trigger signal, the triggering mode of the trigger signal is compared with the preset triggering modes of the trigger signals in the marked preset signal combinations. If the triggering mode of the trigger signal is different from the preset triggering modes of the trigger signals in each marked preset signal combination, the preset function will not be entered, and the control module 10 will perform corresponding actions based on the trigger signal. If the triggering mode of the trigger signal is the same as the preset triggering mode of the trigger signal in one of the marked preset signal combinations, the preset function corresponding to the preset signal combination with the same triggering mode will be executed, and the preset function mode will be entered.

[0052] Method 2: When there are restrictions on the order of operation signals and trigger signals in the preset signal combinations, taking the control module 10 detecting the first touch device being triggered to receive the operation signal as an example, the preset signal combination that receives the operation signal first is selected from all preset signal combinations, and the triggering method of the received operation signal is compared with the preset triggering method of the operation signal in each selected preset signal combination. If the triggering method of the received operation signal is different from the preset triggering method of the operation signal in each selected preset signal combination, the preset function mode will not be entered, and the control module 10 will only control the scissors assembly to perform cutting activities based on the operation signal.

[0053] If the triggering mode of the received operation signal is the same as the preset triggering mode of the operation signal in one or more selected preset signal combinations, the control module 10 marks these one or more preset signal combinations. After detecting that the second triggering device has been triggered and received a trigger signal, the triggering mode of the trigger signal is compared with the preset triggering mode of the trigger signal in each of the marked preset signal combinations. If the triggering mode of the trigger signal is different from the preset triggering mode of the trigger signal in each of the marked preset signal combinations, the preset function will not be entered, and the control module 10 will perform corresponding actions based on the trigger signal. If the triggering mode of the trigger signal is the same as the preset triggering mode of the trigger signal in one of the marked preset signal combinations, the preset function corresponding to the preset signal combination with the same triggering mode will be executed, and the preset function mode will be entered.

[0054] In one example, the control module 10 executes a preset function corresponding to the preset signal combination when the combination of the received operation signal and trigger signal within a preset time period matches a preset signal combination. Specifically, the control module 10 sets a preset time period. When the combination of the operation signal and trigger signal matches the preset signal combination, it must ensure that the entire triggering time from the start to the end of triggering by the two triggering devices (the first triggering device) is less than or equal to this preset time period before executing the preset function corresponding to the preset signal combination. If the entire triggering time is longer than the preset time period, the preset function corresponding to the preset signal combination will not be executed. The preset time period can be configured by the user, for example, less than 5 seconds, preferably less than 3 seconds.

[0055] In one embodiment, please refer to Figure 2 The first triggering device 11 includes an information acquisition module 111 that is communicatively connected to the control module 10, and an operating trigger 112.

[0056] The signal acquisition module 111 is used to acquire operation information indicating that the operating trigger 112 is pressed and send it to the control module 10. Specifically, when the signal acquisition module 111 detects that the operating trigger 112 is pressed, it sends operation information indicating that the operating trigger 112 is pressed to the control module 10. When the control module 10 receives the operation information indicating that the operating trigger 112 is pressed, it controls the blades in the scissor assembly to close and cut. When the signal acquisition module 111 detects that the operating trigger 112 is released, it sends operation information indicating that the operating trigger 112 is released to the control module 10. When the control module 10 receives the operation information indicating that the operating trigger 112 is released, it controls the blades in the scissor assembly to open.

[0057] The signal acquisition module 111 is also used to detect the opening and closing position of the blade in the scissor assembly. The signal acquisition module 11 sends information characterizing the opening and closing position of the blade (e.g., opening and closing angle) to the control module 10. The control module 10 can then monitor the scissor assembly in real time to ensure it is working properly and can adjust the opening and closing angle of the blade based on this information, allowing the user to adjust the angle according to their needs. The portable electric scissor can have multiple signal acquisition modules 111, each corresponding to a specific opening and closing angle. When the user selects an opening angle, the corresponding signal acquisition module 111 is activated. A magnet is mounted on the moving blade 132 of the scissor assembly. When the moving blade 132 rotates, the magnet moves close to the signal acquisition module 111, which is in operation. The signal acquisition module 111 sends the received magnetic signal to the control module 10, which then controls the drive module 131 to stop moving. If the control module 10 does not receive the magnetic signal sent by the signal acquisition module 111 within a set time (e.g., 1 second) after the trigger 112 is pressed, the control module 10 determines that the portable electric tool is working abnormally and issues a set alarm signal, such as a buzzer sound or a voice prompt.

[0058] In this embodiment, the signal acquisition module 111 includes a Hall sensor. The signal acquisition module 111 may also include a magnetoresistive sensor, a potentiometer-based system, an inductive, capacitive, optical system, or a magnetic system that includes fixed and movable components arranged differently.

[0059] In one embodiment, please refer to Figure 3 The portable electric cutting tool also includes a safety switch 16 disposed on the first triggering device 11 and rotatable about a rotation axis.

[0060] The safety switch 16 is used to limit the first triggering device 11 when it is not rotated or pressed, so that the first triggering device 11 cannot be triggered.

[0061] The safety switch 16 is used to release the limit on the first triggering device 11 when it is rotated and pressed, so that the first triggering device 11 can be triggered.

[0062] Incorporating a safety switch in a portable electric cutting tool to limit the first triggering device can further enhance the safety of operating the tool and prevent safety hazards caused by misoperation by non-professional operators.

[0063] In addition, Figure 3 In this example, taking the power switch 15 of a portable electric knife as the second triggering device 12, the preset function mode can be triggered by the combination of the first triggering device 11 (i.e. the aforementioned operating trigger 112) and the power switch 15.

[0064] Specifically, the duration for which the power switch 15 is triggered to control the power-off of the portable electric tool can be set to differ from the duration for which the power switch is triggered in a preset signal combination. This prevents the triggering of the preset function corresponding to the preset signal combination from affecting the triggering of the power-off function of the portable electric tool controlled by the power switch 15. For example, the preset function corresponding to the preset signal combination is that the portable electric tool enters the power-off state when the power switch 15 is pressed and held for 5 seconds, or when the power switch 15 is pressed and held for 2 seconds.

[0065] In one example, the duration for which the power switch 15 is triggered to turn off the power to the portable electric tool is longer than the duration for which the power switch is triggered in a preset signal combination. For example, the preset function corresponding to the preset signal combination is that the portable electric tool enters the off state when the power switch 15 is pressed for 1 second or 3 seconds, or when the power switch 15 is pressed for 5 seconds.

[0066] In one example, please refer to Figure 4 The portable electric cutting tool includes a power-off state (i.e., power-off) and a working state. The preset signal combination is an operation signal of the operating trigger 112 being pressed for 1 second and a trigger signal of the power switch 15 being pressed for 2 seconds. The preset function corresponding to this preset signal combination is to control the portable electric cutting tool to enter the power-off state.

[0067] In step S10, the portable electric cutter is in the off state. At this time, even when the trigger 112 is pressed, the portable electric cutter will not perform any cutting activity. In step S11, when the control module 10 detects that the power switch 15 has been briefly pressed, it enters the working state. At this time, when the trigger 112 is pressed, the portable electric cutter will perform normal cutting activity, and the blade of the portable electric cutter is initially open. In step S12, when the trigger 112 is pressed, the blade closes. In step S13, when the trigger 112 is released, the blade opens. When the control module 10 detects an operation signal lasting 1 second and a trigger signal lasting 2 seconds, it executes the preset function of controlling the portable electric cutter to enter the off state, that is, controlling the portable electric cutter to enter the off state from the working state. Additionally, the control module 10 can be set to detect when the portable electric cutter has been pressed for a certain period of time (…). Figure 2 (Taking 60 seconds as an example) When there is no operation and no signal is detected, the portable electric tool is controlled to switch from the working state to the off state; or, when the power switch 15 is detected to be pressed and held for 4 seconds, the portable electric tool is controlled to switch from the working state to the off state.

[0068] In another example, please refer to Figure 5 The portable electric cutting tool includes a power off state (i.e., power off), a standby state, a working state, and a sleep state. The preset signal combination is a trigger signal of the power switch 15 being pressed and held for 2 seconds and an operation signal of the operation trigger 112 being clicked. The preset function corresponding to this preset signal combination is to control the portable electric cutting tool to switch between standby state, working state, and sleep state.

[0069] In step S20, the portable electric cutter is in the off state. At this time, even if the operating trigger 112 is pressed, the portable electric cutter will not perform any cutting activity. In step S21, when the control module 10 detects that the power switch 15 has been briefly pressed, it enters the standby state. At this time, even if the operating trigger 112 is pressed, the portable electric cutter still cannot perform any cutting activity, but some basic parameter settings can be made. In step S22, when the control module 10 detects a single-click operation signal and a trigger signal lasting 2 seconds, combined with the portable electric cutter being in the standby state, it executes the preset function to control the portable electric cutter to enter the working state. The control module 10 controls the portable electric cutter to enter the working state. At this time, when the operating trigger 112 is pressed, the portable electric cutter will perform normal cutting activity. The blade of the portable electric cutter is initially open. When the operating trigger 112 is pressed in step S23, the blade is closed. When the operating trigger 112 is released in step S24, the blade is open.

[0070] In step S22, when the portable electric tool is in working state, the control module 10, upon detecting a single-click operation signal and a trigger signal lasting 2 seconds, executes a preset function to control the portable electric tool to enter a sleep state, in conjunction with the portable electric tool being in working state.

[0071] In step S25, when the portable electric tool is in a dormant state, the control module 10, upon detecting a single-click operation signal and a trigger signal lasting 2 seconds, combines the dormant state status of the portable electric tool with the preset function of controlling the portable electric tool to enter the working state.

[0072] In addition, when the portable electric tool is in operation, the control module 10 can be configured to detect when the portable electric tool is in operation for a certain period of time ( Figure 2 When no signal is detected for 60 seconds (for example), the control module 10 controls the portable electric tool to enter a sleep state; and when the control module 10 detects that the portable electric tool has been in a sleep state for another period of time (taking 60 seconds as an example), the control module 10 controls the portable electric tool to enter a sleep state. Figure 2 (Taking 10 minutes as an example) When no signal is detected, the portable electric tool is controlled to enter the power-off state. The control module 10 will also control the portable electric tool to enter the power-off state when it detects that the power switch 15 is pressed and held for 4 seconds.

[0073] In this embodiment, a combination of two triggering devices is used to control the portable electric knife to enter a preset function mode. Since there are two triggering devices that need to be operated separately, the user needs to use both hands to complete the control operation to enter the preset function mode. Compared with operating a single triggering device to enter the preset function mode, this reduces the safety hazards during operation and improves safety. It also reduces the possibility of accidentally entering the preset function mode and improves the user experience.

[0074] The second embodiment of the present invention relates to a control method applied to the control module of the portable electric tool in the first embodiment. For a detailed description of the portable electric tool, please refer to the first embodiment.

[0075] The specific flow of the control method in this embodiment is as follows: Figure 6 As shown.

[0076] Step 101: In response to the operation signal sent when the first triggering device is triggered, control the scissor assembly to work.

[0077] Step 102: Receive the trigger signal sent when the second triggering device is triggered.

[0078] Step 103: If the combination of the received operation signal and trigger signal matches the preset signal combination, execute the preset function corresponding to the preset signal combination.

[0079] In one embodiment, step 103 includes: if the combination of operation signal and trigger signal received within a preset time period matches a preset signal combination, executing a preset function corresponding to the preset signal combination.

[0080] In another embodiment, the preset signal combination includes any one or any combination of the following: receiving an operation signal and a trigger signal at the same time, and / or receiving an operation signal obtained by triggering a first triggering device in a first manner and a trigger signal obtained by triggering a second triggering device in a second manner; for example: the preset signal combination is receiving an operation signal and a trigger signal at the same time, then step 103 includes: if an operation signal and a trigger signal are received at the same time, executing a preset function corresponding to the preset signal combination; as another example: the preset signal combination is receiving an operation signal obtained by triggering a first triggering device in a first manner and a trigger signal obtained by triggering a second triggering device in a second manner, then step 103 includes: if an operation signal obtained by triggering a first triggering device in a first manner and a trigger signal obtained by triggering a second triggering device in a second manner are received, executing a preset function corresponding to the preset signal combination.

[0081] The preset signal combination includes: receiving an operation signal and a trigger signal simultaneously, and receiving an operation signal obtained by triggering a first triggering device in a first manner and a trigger signal obtained by triggering a second triggering device in a second manner; both of these methods can be used to trigger the execution of a preset function corresponding to the preset signal combination. Since the first embodiment and this embodiment correspond to each other, this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment remain valid in this embodiment, and the technical effects achievable in the first embodiment can also be achieved in this embodiment. To reduce repetition, they will not be repeated here. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.
