[0015] In order to further understand the content of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. Embodiment 1

[0016] This embodiment provides Figure 1-3 A laser beauty hand tool 1 with an anti-mistouch function is shown, comprising a grip portion 2, on which is provided a button 3 for controlling the laser energy output of the hand tool 1; the grip portion 2 is also provided with a touch piece 4 for sensing human body contact, and a control module 6 with a sensing capacitor 5 is provided under the touch piece 4, and the control module 6 is also provided with a circuit for cutting off the laser energy supply.

[0017] The touch piece 4 in this embodiment is equivalent to the safety of the key 3. Only when the touch piece 4 detects human skin, the operation of the key 3 can be executed.

[0018] The contact piece 4 is adjacent to the button 3 . When the hand tool 1 is held, the button 3 is pressed by the index finger and the contact piece 4 is contacted by the middle finger.

[0019] When the user operates the hand tool 1 during use, he first grasps the grip portion 2 and places his index finger on the button 3 , while the middle finger contacts the contact piece 4 .

[0020] When the user points the treatment head at the skin and presses button 3, if the touch piece 4 detects the skin (middle finger), the system determines it as a normal operation and allows the treatment head to work.

[0021] If the touch sheet 4 does not sense the skin during use, it is determined as a risk of accidental touch, and the button 3 becomes ineffective, and the treatment head stops working.

[0022] The system will continuously monitor the status of the hand tool 1 and the user's operating intention. If normal operation is not detected within a certain period of time, the power supply of the hand tool 1 will be automatically turned off to ensure safety. Embodiment 2

[0023] like Figure 1-3 As shown, the second embodiment provides a laser beauty system with an anti-mistouch function, comprising a hand tool 1, and a button 3 and a touch sheet 4 provided on a gripping portion 2 of the hand tool 1, wherein the button 3 is used to control the output of laser energy of the hand tool 1; A control module 6 is provided on the gripping portion 2 of the hand tool 1. The control module 6 is provided with an inductive capacitor 5 and is located below the touch sheet 4. The inductive capacitor 5 is used to receive a touch signal and send it to a host. The host receives the touch signal and sends instructions to the control module 6 to control the output of the laser energy of the hand tool 1. Embodiment 3

[0024] like Figure 1 ,2 As shown in FIG. 4 , this embodiment 3 provides a method for preventing accidental touch of a laser beauty system with an accidental touch prevention function as described in embodiment 2, and the method comprises the following steps: Step 1, first detect the state of the contact piece 4; Step 2, secondly, detect the state of button 3; When it is detected that the contact sheet 4 is not pressed in step 1 and the button 3 is not pressed in step 2, the laser energy output is not allowed; it is determined that no operation is currently being performed, and if there is laser output, the laser output is disconnected; When it is detected that the contact piece 4 is pressed in step 1, but the button 3 is not pressed, it is determined that the doctor has grasped the gripping portion 2 of the handpiece 1 and is ready to start treatment; then the button state in step 2 is continuously detected until it is detected that the button state in step 2 is pressed, allowing the laser energy to be output; When it is detected that the touch sheet 4 is not pressed in step 1, and the button 3 is pressed in step 2, laser energy output is not allowed, and it is determined that the current operation is an incorrect touch. The hand tool 1 sends the corresponding error flag to the host and re-checks steps 1 and 2. At the same time, if there is currently laser output, the laser output is disconnected, and then steps 1 and 2 are re-checked.

[0025] After determining the state of touch piece 4, the signal state of button 3 is re-detected and filtered. When the current state of button 3 is pressed and the host state is ready, it is judged that the doctor has started treatment, and laser output is performed according to the parameters set by the host; if button 3 is not pressed, it is judged that the doctor is still preparing. At this time, if there is laser output, the laser output needs to be disconnected and the touch piece 4 state detection process is returned to re-detect the state of touch piece 4 to confirm that the doctor is always in the state of preparing to start treatment (that is, the state of touch piece 4 is always pressed).

[0026] During the treatment, the status of the touch piece 4 and the button 3 are detected in real time. When the touch piece 4 is not disconnected and the button 3 is disconnected, the treatment is judged to be over, that is, the doctor actively releases the button 3. At this time, the laser output is disconnected and returns to the initial state, and a new round of detection is started; when the touch piece 4 is disconnected, it is judged to be an abnormal disconnection state. At this time, the laser output is disconnected and returns to the initial state, and the handpiece sends the corresponding error flag to the host.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
