The invention relates to a
hand tool for
hair removal by
laser light. The
hand tool includes a
hand tool housing and a hand tool core, the
handle tool housing is of a detachable structure with an opening in the front end, and the
handle core is disposed in the
handle tool housing and includes an annular structure, a light transmitting layer, a
laser device and a negative pressure channel; the
laser device emits light to the front end through the light transmitting layer, at least one negative pressure suction hole is formed in the top of the annular structure and connected with the negative pressure channel, and during work, a vacuum negative pressure space is formed among the annular structure, the light transmitting layer, the inner wall of the housing and the
skin. The structure designis ingenious, a vacuum negative pressure technology and a
laser technology are used and combined, the
skin is sucked into the opening of the front end of the hand tool housing instantly, vacuum negative pressure directly acts on the treated
skin and instantaneously blocks transmission of pain information, the laser device instantaneously emits the
laser light, and the
laser light enters the
subcutaneous tissue of the skin to destroy the black tissue of the hair, so that the effect of rapid and painless
hair removal by the
laser light is achieved without the need of injecting anesthetics in advance, the problem of
cross infection is avoided, and meanwhile, the
hair removal effect and hair removal efficiency are enhanced.
