[0037] Compared with the traditional working status display method, this power tool status display method has added multiple functions, which can clearly remind users in a striking way, and at the same time provide better visual effects for the display of a single working status, and has a wide range of applications.
[0038] In one embodiment of the present disclosure, see Figure 1 and Figure 2 , a plurality of light-isolating areas 6 are evenly distributed in the light-isolating cover 1, and the light sources 3 are located in the light-isolating areas 6. In this way, the plurality of light sources 3 are isolated by the light-isolating cover 1 and the light-isolating areas 6 therein, so that the light interference between adjacent light sources 3 in adjacent light-isolating areas 6 can be avoided, and the light sources 3 can be prevented from being damaged by external collision.
[0039] Optionally, a plurality of display holes 7 connected to the light isolation area 6 are evenly distributed on the top wall of the light isolation cover 1. In this way, the light source 3 in the light isolation area 6 is displayed through the display holes 7, so that all light sources 3 in the same light isolation area 6 can be displayed at the same position.
[0040] Furthermore, by using the display hole 7 to display all the light sources 3 in the corresponding light isolation area 6, various states and display modes can be observed visually from the appearance, and various states and display modes can be distinguished easily.
[0041] In an example, four light-isolating areas 6 are evenly distributed in the light-isolating cover 1 .
[0042] In one embodiment of the present disclosure, the light source 3 is an LED light source, and at least two LED light sources are arranged in any light isolation area 6. In this way, different working states and working modes of the power tool can be displayed in a variety of different ways through two or more LED light sources.
[0043] In one example, the LED light source may be a monochromatic LED lamp.
[0044] In another example, the LED light source may be a dual-color LED lamp.
[0045] Optionally, the LED light source in the same light-isolating area 6 can display different color modes such as single color, double color or combination color. In this way, the electric tool can realize display modes such as single color, double color or combination color.

[0047] In one embodiment of the present disclosure, see Figure 4 , the light source 3 is an RGB light source; and one RGB light source is arranged in any light-isolating area 6. In this way, different working states and working modes of the power tool can be displayed in a variety of different ways through the RGB light source.
[0048] In one example, the RGB light source may be a monochromatic RGB lamp.
[0049] In another example, the RGB light source may be a dual-color RGB lamp.
[0050] Optionally, the RGB light source in the same light-isolating area 6 can display different color modes such as single color, double color or combined color. In this way, the electric tool can realize display modes such as single color, double color or combined color.
[0051] In one example, an RGB lamp is disposed in any light-isolating area 6 , and an RGB lamp can display different modes such as single color, double color or combination color.
[0052] In one embodiment of the present disclosure, see Figure 1 A display surface sticker 8 is provided on the top of the light-isolating cover 1. In this way, it is convenient for the user to visually view and distinguish various states and display modes of the electric tool.
[0053] In one embodiment of the present disclosure, see Figure 1 The single-chip computer system 5 includes a single-chip computer 9 and a logic chip 10. The single-chip computer 9 is electrically connected to the button 4, and the logic chip 10 is electrically connected to the single-chip computer 9 and the light source 3 respectively; the single-chip computer 9 controls the lighting or extinguishing and brightness of the light source 3 through the logic chip 10. In this way, the single-chip computer 9 and the logic chip 10 form a hardware circuit, and through program control, electronic impact simulates mechanical impact and realizes synchronous control of multiple light sources 3.
[0054] In one example, the logic chip 10 is a 74 series logic chip.
[0055] In one embodiment of the present disclosure, see Figure 5 , 8 LED lights are arranged in the light shield 1, the single chip microcomputer 9 is connected to the 74 series logic chip 10, and the single chip microcomputer 9 is connected to the button 4 ( Figure 4The middle button is marked with SW), the logic chip 10 is connected to the 8-way LED lights, and the signal is input through the button 4. After the single-chip microcomputer 9 receives the signal, the single-chip microcomputer 9 controls the power tool to enter the corresponding working state. The single-chip microcomputer 9 synchronously controls the 8-way LED lights through the 74 series logic chip 10, so that the 8-way LED lights are turned on or off, or the brightness changes, so as to display the working state.
[0056] In another embodiment of the present disclosure, see Figure 6 , 4 RGB lights are arranged in the light shield 1, the single chip microcomputer 9 is connected to the 74 series logic chip 10, and the single chip microcomputer 9 is connected to the button 4 ( Figure 5 The middle button is marked with SW), the logic chip 10 is connected to 4 RGB lights, and a signal is input through button 4. After the single-chip microcomputer 9 receives the signal, the single-chip microcomputer 9 controls the power tool to enter the corresponding working state. The single-chip microcomputer 9 synchronously controls the 4 RGB lights through the 74 series logic chip 10, so that the 4 RGB lights are turned on or off, or the brightness changes, so as to display the working state.
[0057] The disclosed embodiment also provides a control method of a device based on the power tool status display mode, see Figure 7 , including the following steps: Step 1: the user presses the button 4; Step 2: obtaining the level state of the button 4; Step 3: judging the user's operation according to the level state and entering the next control state; Step 4: the logic chip 10 controls the light source 3 to display according to the control state.
[0058] In the disclosed embodiment, the user presses the button 4, causing the level state of the button 4 to change. The level state of the button 4 is detected by the single-chip microcomputer 9, that is, the single-chip microcomputer 9 reads the high and low levels when the button 4 is pressed or released. The single-chip microcomputer 9 determines the user's operation based on the change in the level state of the button 4, that is, the pressing duration and number of times the button 4 is pressed are determined based on the change in the level state of the button 4, and then the user's control operation is determined, so that the power tool changes its working state or working mode. The logic chip 10 synchronously controls the light source 3 to change according to the determination result of the single-chip microcomputer 9, so as to display the working state or working mode of the power tool.
[0059] In one example, the number of key 4 is one.
[0060] In another example, the number of keys 4 is at least two.
[0061] In one embodiment of the present disclosure, step 2 includes: the button 4 is in a low level state after being pressed, and is in a high level state after being released. In this way, the single-chip microcomputer 9 can accurately read the level change when the button 4 is pressed or released, and then the single-chip microcomputer 9 can accurately determine the user's operation and realize accurate adjustment of the working mode of the power tool.
[0062] In one embodiment of the present disclosure, step 3 includes: if the pressing time of button 4 is less than 200 milliseconds, it is determined as a short press; if the short press is repeated within 200 milliseconds after the short press ends, it is determined as a double press; if the pressing time of button 4 is greater than 200 milliseconds, it is determined as a long press. In this way, the working state of the power tool can be changed by short press, long press, double press, etc., and the user operation is flexible and simple.
[0063] Optionally, the single-chip computer 9 detects the electrical level state of the key 4 once every millisecond. When the key 4 is pressed, the single-chip computer 9 receives a low-level signal, and the counter in the single-chip computer 9 starts counting. When it is recorded that the key 4 is pressed for 10 milliseconds, the single-chip computer 9 determines that the key 4 has been pressed. At this time, the counter is cleared and starts counting again. When it is recorded that the key 4 is pressed for less than 200 milliseconds, the pressing of the key 4 is judged as a short press.
[0064] Furthermore, if another short press operation is performed within 200 milliseconds after the short press is completed, the two presses of the button 4 are determined as double clicks.
[0065] Furthermore, if after the counter is cleared and restarted to count, if it is recorded that the time when the button 4 is pressed is greater than 200 milliseconds, the pressing of the button 4 is determined as a long press.
[0066] In the above embodiment, the single chip microcomputer 9 adjusts the working state or working mode of the power tool according to the user's short press, double press, or long press operation, which is simple and flexible to operate and realizes autonomous control of the operating state of the power tool.
[0067] In one embodiment of the present disclosure, step 4 includes: the logic chip 10 controls the lighting or extinguishing of the light source 3; the logic chip 10 controls the brightness of the light source 3. In this way, the display state of the light source 3 can be adjusted by the logic chip 10, so that the display of different working states of the power tool can be realized, which is eye-catching and clear, and convenient for users to view accurately.
[0068] In one example, the light source 3 is an LED lamp, and the logic chip 10 controls the output of multiple high and low levels according to the change of the level state of the key 4 detected by the single-chip microcomputer 9 to control the lighting or extinguishing of the LED lamp.
[0069] In another example, the light source 3 is an LED lamp, and the logic chip 10 controls the output PWM pulse according to the change of the level state of the key 4 detected by the single chip microcomputer 9 to control the brightness of the LED lamp.
[0070] In the disclosed embodiment, at least two LED lights or one RGB light in any light-isolating area 6 can realize flashing, flowing, breathing and other combination display modes under the control of the single-chip microcomputer 9 and the logic chip 10, thereby realizing a diversified way of reminding the user of different working states and working modes.
[0071] In one embodiment of the present disclosure, the inventor takes one of the currently used control modes as an example, and the control mode has the following control states:

[0081] Function editing state: In the function editing state, the initialization data of each working state and mode of the power tool can be edited;
[0082] The editing modes include:
[0083] (1) Speed Editing Mode: The maximum speed can be adjusted by a short press of button 4. The mode is visually indicated by the combination of different colored LED lights and the brightness change of the breathing light. The mode is locked and switched to the next state by short pressing button 4 twice.
[0084] (2) Acceleration curve duration editing mode: The acceleration curve duration can be adjusted by short pressing button 4; the mode visual prompt is achieved by coordinating the brightness changes of LED lights of different colors and breathing lights; the mode is locked and switched to the next state by short pressing button 4 twice.

[0088] To sum up, the above functions are only examples at present. The actual functions are more diversified and no further examples will be given.
[0089] In the above embodiment, the gun-type low-power electric tool adopts this control method. When the button 4 is short pressed once, the working state can be switched in rotation; when the button 4 is short pressed twice, it can be switched to the next mode cycle; when the button 4 is long pressed once, the working state can be switched in rotation again. When the button 4 is short pressed three times, the current working state can be locked or released; when the working state is locked, the user can freely edit the speed, torque value, acceleration curvature by short pressing the button 4, and store the edited values in the memory module of the single-chip computer 9; when the working state is released, the electric tool is started, and the operating state is the working state edited by the user. The above description is only one of the composite control display methods.
