AI Technical Summary

Technical Problem

Existing laser hair removal devices cannot accurately obtain skin color information, resulting in low accuracy and reliability of laser activation, and failing to meet users' safety requirements.

Method used

The system employs a detection component and a first detector. The detection component includes a cooling head. The detector emits RGB light signals or monochromatic light signals towards the reflector to obtain skin color information. It also confirms that the detection component is in contact with the skin through contact capacitance signals. The controller determines the working status of the laser based on the reflection signal and capacitance signal.

Benefits of technology

It improves the accuracy of contact detection in laser hair removal devices, ensuring accurate laser startup and safe use, avoiding accidental triggering, and providing a comfortable treatment experience.

Abstract

The utility model provides a laser hair removal device, and relates to the technical field of medical cosmetology. The device comprises a base, and a detection assembly, a first detector, a controller and a laser which are arranged on the base, wherein the detection assembly, the first detector and the laser are electrically connected with the controller respectively; the first detector emits an RGB optical signal to the reflector so as to obtain skin color information of human skin according to a first reflected signal which is reflected back, or emits a first monochromatic light signal to the reflector and receives a second reflected signal which is reflected back so as to confirm that a detection surface where the first detector is located is in contact with the reflector; the detection assembly obtains a contact capacitance signal after contacting with the reflector to confirm that the contacted reflector is the human skin; and the controller outputs the received skin color information and judges that the laser can enter a working state or controls the laser to stop working according to the received second reflection signal and the contact capacitance signal. The laser hair removal device is high in contact judgment accuracy and capable of obtaining skin color information of human skin.
