The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
The depilating instrument (also called depilating device) is a very explosive depilating product in recent years, and can quickly and safely act on epidermal hair follicles to achieve depilation. The principle of the hair removal instrument is that laser or strong pulse light penetrates through the epidermis of a human body and reaches hair follicles, and melanin in the hair follicles absorbs the energy of the light to generate instant high temperature, so that the hair is burnt and withered and enters a dormant period, and the effect of inhibiting the growth of sweat hair is achieved.
At present, when the conventional depilating instrument is used for polishing and depilating, the polishing cannot be continuously and quickly performed. Because the capacitor supplied by the light-emitting tube needs a certain time to charge after discharging, the time is different according to the capacitance of the capacitor, and the conventional depilating instrument is about 500 milliseconds to 1 second. In the process of capacitor charging, if a user triggers the light-emitting tube, the voltage provided by the capacitor cannot meet the requirement of the light-emitting tube due to the fact that the capacitor is not charged, and the depilator can generate missed flashing.
Based on this, the present embodiment provides a depilating apparatus and a control method thereof, in which multiple sets of charge and discharge units are adopted, and the multiple sets of charge and discharge units are controlled by a switch to sequentially switch charge and discharge, and when the light is continuously and rapidly turned on, one set of charge and discharge units discharges electricity, and the other set of charge and discharge units discharges electricity; meanwhile, the power supply module charges the discharged charge-discharge unit, and so on; therefore, continuous and rapid polishing is realized, missed flashing is avoided, the polishing efficiency is improved, and the user experience is improved.

Each set of the charge and discharge units 12 alternately discharges to the light emitting tube 13 in sequence, and the control of the charge and discharge units 12 after discharge to charge means that: for example, after the first group of charge and discharge units discharge to the light emitting tube 13, the control module 15 controls the second group of charge and discharge units to discharge to the light emitting tube 13, and simultaneously controls the power module 11 to charge the first group of charge and discharge units, after the first group of charge and discharge units charge, the control module 15 waits for the control module 15 to control the second group of charge and discharge units to discharge to the light emitting tube 13 again after the second group of charge and discharge units discharge, and simultaneously the control module 15 controls the second group of charge and discharge units to charge.
