Description

TECHNICAL FIELD

[0001] The utility model belongs to the depilation technical field, concretely relates to a galvanometer control device for depilation instrument. BACKGROUND

[0002] Laser depilation is the use of the "selective photothermal effect" of laser, and the laser of specific wavelength is used to pass through the epidermis and directly irradiate the hair follicle. The melanin of hair follicle and hair shaft selectively absorbs light energy, and the heat effect generated thereby causes the hair follicle to necrose, so that the hair no longer grows. The effect of laser depilation is irreversible due to the process of heat absorption and necrosis of the hair follicle, and it also does not damage the normal skin tissue. Therefore, laser depilation can achieve the effect of permanent depilation. With the continuous improvement of the quality of life, more and more people begin to pay attention to maintenance and beauty, and hope that their skin is delicate, smooth and elastic. Therefore, a large number of beauty instruments have emerged.

[0003] At present, when a femtosecond laser is used, in order to avoid laser divergence and ensure that the laser directly irradiates the hair follicle, the laser beam is often shaped, for example, the deflection scanning control can be performed by a galvanometer. The galvanometer controls the deflection angle and direction of the light beam by mechanical vibration, and realizes the accurate regulation and control of the laser beam. The lens is connected with the galvanometer motor, and the galvanometer motor is an excellent vector scanning device. It drives the laser reflecting lens to realize the beam guidance in a limited swing angle range. Since the galvanometer is a fast and precise machine, it is required to have a larger acceleration from one working state to another. In this way, the idle time of scanning is infinitely small, and the fast response performance of the galvanometer is better.

[0004] The utility model discloses a kind of connection structure of scanning galvanometer motor output shaft and galvanometer lens, and lens is connected with scanning motor output shaft by connecting piece, and scanning efficiency mainly depends on the response speed of scanning motor, if directly applied in laser depilation direction, with certain limitation.

[0005] Therefore, the present scheme proposes a kind of galvanometer control device for depilation instrument, solves the technical problem of how to improve the fast response performance of galvanometer. UTILITY MODEL CONTENT
