[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0028] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an intelligent electric hair clipper includes a main unit 1 and a blade head 2 on the main unit 1. The main unit 1 includes a housing 10, and a circuit board 11 is disposed in the housing 10. The circuit board 11 is provided with an intelligent chip 12, a tactile switch 13, a processor 14, and a power supply 15. A drive source 16 is connected to the end face of the circuit board 11. The intelligent chip 12 and the tactile switch 13 are electrically connected to the circuit board 11, and the processor 15 is electrically connected to the circuit board 11. The power supply 15 provides power to the circuit board 11, the intelligent chip 12, the tactile switch 13, and the processor 14.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on the embodiment, the circuit board 11 is a PCB circuit board, which has good assemblability and reliability and is easy to use.

[0030] Example 3: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on Embodiment 1 or Embodiment 2, the smart chip 12 uses an accelerometer, and the processor 14 uses a main control MCU. The accelerometer can measure the acceleration generated when the user moves and the acceleration changes due to gravity. By detecting the acceleration, the current direction and angle of the hair clipper, as well as its movement speed, direction of movement, or vibration, can be calculated. By setting different computer states, the current direction, angle, and speed of the hair clipper can be determined, and the system can be configured to provide different feedback for different states. When the clipper is detected to have fallen, the control stops the rotation of the clippers to prevent damage to the blades and other components. When the user's movement speed is detected to be too fast, the motor speed is adjusted from 6000 rpm to match the user's movement speed, maintaining a range of 6000-15000 rpm. The faster the user moves, the higher the speed, ensuring that the cutting speed increases synchronously when the user moves too quickly, preventing hair pulling and pain. Simultaneously, when the user is cutting hair at a steady, slower pace, the speed remains stable to avoid wasting electricity, noise, or vibration caused by inappropriate speeds, thus improving the user experience.

[0031] Example 4: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, based on Embodiment 1, Embodiment 2, or Embodiment 3, it can be further described that it also includes a charging interface 17 (charging interface PCBA) disposed on the circuit board 11, and the power supply 15 is a storage battery, which is more conducive to charging and thus improves the usage time.

[0032] Example 5: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4, further, an alarm 18 is provided on the circuit board 11. The alarm 18 is a buzzer. When the user's haircutting speed exceeds a preset speed threshold, the circuit board 11 controls the buzzer to sound, thus alerting the user. It is also worth noting that a display screen 19 is provided on the housing 10. The display screen 19 is connected to the circuit board 11 and the power supply 15. The power supply 15 provides power to the display screen 19, while the circuit board 11 provides power to the display screen 18. Furthermore, the display screen 19 uses interactive methods such as prompts or flashing lights for alerting. In this invention, the display screen 19 can show the current tilt angle of the hair clipper, making it convenient for users to read intuitively and improving the human-computer interaction experience. For example, the angle can be displayed in various ways; in this example, the angle value 191 is printed on the housing 10, and the display screen 19 shows an arrow 192 indicating the corresponding angle value 191 on the housing 10. It is also worth emphasizing that in this invention, the smart chip 12, tactile switch 13, processor 14, power supply 15, charging interface 16, buzzer, and display screen 19 are all soldered and fixed to the circuit board 11, and all of these components are electrically connected to the circuit board 11.

[0033] Example 6: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, based on Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, or Embodiment 5, the housing 10 includes an upper housing 101 and a lower housing 102. A button 103 is provided on the upper housing 101, and the button 103 is electrically connected to the tactile switch 13 (in this embodiment, the button 103 includes operation button one and operation button two). The blade portion 2 is installed at the front end of the upper housing 101 and the lower housing 102, and a tail cover 104 is installed at the rear end of the upper housing 101 and the lower housing 102. The tail cover 104 is fixed to the rear end of the upper housing 101 and the lower housing 102 by a snap-fit ​​method, serving to fix the housing 10 and for aesthetic purposes. It is worth noting that the button 103 is movably assembled on the upper housing 101 by a snap-fit ​​method, and the button 103 is in contact with the tactile switch 13. It is also worth noting that the circuit board 11 is fixed to the housing 10 by screws. Finally, it should be emphasized that the outer surface of the housing 10 is covered with a protective shell 105, which on the one hand helps to fix the upper shell 101 and the lower shell 102 into the housing 10, and on the other hand provides protection.

[0034] Example 7: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, or Embodiment 6, the drive source 16 is a motor. The motor is fixed in the housing 10 by a fixing bracket 161, and the fixing bracket 161 and the motor are fixed by screws. The motor is connected to the circuit board 11 through wires, and the circuit board 11 controls the motor to stop rotating to prevent damage to the blade and other structures in the cutter head 2. It should also be noted that the motor is provided with a swing arm 162, which contacts the cutter head 2.

[0035] Example 8: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, based on Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, Embodiment 6, or Embodiment 7, the cutter head portion 2 includes a fixed cutter 21 disposed on the front end of the housing 10, a movable cutter 22 disposed on the fixed cutter 21, and a torsion spring 23 disposed between the movable cutter 22 and the housing 10. The elastic force of the torsion spring 23 presses the movable cutter 22, so that the movable cutter 22 and the fixed cutter 21 are always in contact under the pressure of the torsion spring 23, and it also plays the role of limiting the movement range of the movable cutter 22 and damping vibration. Specifically, the torsion spring 23 includes a body 231, with a spring arm 232 at one end and a root 233 at the other end. The spring arm 232 is assembled with the moving blade 22, and the root 233 is fixed to the housing 10 by a snap-fit. The fixed blade 21 is detachably fixed to the housing 10 by a snap-fit. The moving blade 22 is assembled on the moving blade 21 and abuts against the inner surface of the moving blade 21. It is worth emphasizing that the moving blade 21 is provided with a transmission interface 211, which contacts the rocker arm 162, thus transmitting power.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, pressing button 103 activates the corresponding tactile switch 13, triggering it to begin operation. The main control chip MCU controls the circuit board 11, which transmits current from the power supply 15 to the drive source 16 via the circuit board 11 and wires. Since the drive source 16 is a motor, it rotates at a speed of 6000 rpm. The motor's swing arm 162 drives the moving blade 22 in a linear reciprocating motion. This linear reciprocating motion of the moving blade 22 relative to the fixed blade 21 cuts the hair entering the blade teeth, thus achieving the hair-cutting and hair-shaping functions. The intelligent chip 12 uses an accelerometer, which measures the acceleration generated during user movement and the acceleration caused by gravity. Speed ​​changes are detected by measuring acceleration to calculate the current direction, angle, speed, direction, and vibration of the clipper. Computer settings for different states allow for the determination of the clipper's current direction, angle, and speed, with different feedback mechanisms for each state. For example, if the clipper is detected to be falling, the motor is stopped to prevent damage to the blades and other components. If the user's instantaneous movement speed is detected to be too fast, the motor speed is adjusted from 6000 rpm to match the user's movement speed, maintaining a range of 6000-15000 rpm. The faster the user's movement, the higher the motor speed, ensuring proper trimming even during rapid movements. The speed can be increased synchronously to avoid pain caused by pulling hair. Simultaneously, when the user cuts hair at a steady, slower speed, the rotation speed remains stable to avoid power waste, noise, and vibration caused by inappropriate rotation speeds, thus improving the user experience. If the user's hair-cutting speed exceeds a preset speed threshold, the invention controls the alarm 18 to sound, or the display screen 19 to prompt or flash an light to remind the user. The display screen 19 can display the current tilt angle of the hair clipper for easy and intuitive reading, enhancing the human-computer interaction experience. The angle can be displayed in various ways; for example, in this example, the angle value 191 is printed on the upper shell 101, and the display screen 19 shows an arrow 192 indicating the corresponding angle value 191 on the outer shell. Pressing... Button 103 activates the corresponding touch switch 13 to enter the angle setting mode. In this mode, the user can set any angle as the direction of linear movement. If the user deviates from this angle during haircutting, the invention will be triggered, and the buzzer will sound, the display screen 19 will display a prompt, or the light will flash to remind the user. This helps the user to cut a haircut with an accurate straight line, such as bangs, buzz cut, slicked-back hair, and a straight nape of the neck. When finished using the hair clipper, pressing button 103 will turn off the power and enter standby mode. In standby mode, when the user picks up the hair clipper, the accelerometer will detect the change in acceleration and control the display screen 19 to display information such as battery level. When the user needs to charge the clipper, the charging cable can be inserted into the charging port 16.

[0037] This invention utilizes an accelerometer to measure the acceleration generated when a user moves, as well as the acceleration caused by gravity. By detecting the acceleration, the current direction and angle of the hair clipper, as well as the movement speed and direction, can be calculated. The angle and movement speed information can be displayed on the display screen 19 or sent to the user's mobile terminal (such as a smartphone or other smart device). The user can see the angle of their haircut in real time to help the hairdresser control the hairstyle. This invention addresses the shortcomings of existing electric hair clippers, which only offer basic trimming functions and lack the ability to detect and provide feedback on the clipper's position and orientation. Utilizing an accelerometer, the invention detects the clipper's speed and direction relative to gravity to determine if it is in a falling state. When a fall is detected, the motor is instantly stopped to prevent damage to the blades and internal structure. This overcomes the limitation of traditional hair clippers that can only be controlled by a switch or button, preventing damage to the blades caused by the motor continuing to operate during a fall. The invention uses an accelerometer to detect the clipper's speed and controls the motor to accelerate at a matched speed. This ensures that if the user moves too quickly, the trimming speed increases synchronously to avoid pulling and causing pain. Simultaneously, the motor speed remains stable when the user moves at a steady, slower pace, avoiding power waste, noise, and vibration caused by inappropriate speeds, thus improving the user experience. If the user's movement speed exceeds a preset speed threshold, the system will activate a buzzer, display a warning, or flash an indicator light. The interactive method reminds users, which helps to solve the problem of the constant speed of traditional hair clippers, avoiding the problem of hair being pulled and causing pain when the user moves too fast. This invention allows users to preset custom movement directions and trajectories, and uses an accelerometer to sense the angle and speed of the hair clipper. When the user deviates from the preset trajectory or direction, it will remind the user through sound, display screen, or indicator light, thereby helping the user to cut accurate straight hairstyles, such as bangs, buzz cuts, slicked-back hair, and nape of the neck, etc. It can realize the function of users correcting the direction when cutting their own hair, which solves the problem that traditional hair clippers can only rely on the user's technique and experience to control the straight line, horizontal line or other specific trajectory, avoiding the possibility of haircutting errors and ruining the hairstyle. The accelerometer of this invention can detect any form of acceleration change. When the user picks up the product, the accelerometer reacts and instantly lights up the display screen (screen and indicator light, displaying battery level, etc.), while traditional hair clippers require pressing a switch to wake up the machine.
