As shown in fig. 1 and fig. 2, a multiline laser control method provided in an embodiment of the present invention includes:

s10, when an operation instruction is detected, sending a first control signal and a second control signal; the first control signal is used to control the laser 10 to emit an initial beam 101 towards the optically transparent member 20.

In this embodiment, the operation instruction may be an operation instruction of a user, for example, an on instruction, and when the main controller 40 receives the operation instruction of the user, the main controller 40 may output the first control signal and the second control signal at the same time; it can be understood that, when the laser depilating apparatus is applied to a depilating apparatus, the main controller 40 may be forced to output the first control signal and the second control signal at the same time when the depilating apparatus is turned on, so as to control the laser 10 to start, and the main controller 40 may also output an operation instruction through an external device, for example, the mobile phone APP may output an operation instruction through the mobile phone APP when the mobile phone APP interacts with the depilating apparatus.

The specific implementation manner of the step S10 includes sending a timing pulse to the voltage amplifier 50 when an operation instruction of the user is detected; in response to the timing pulses, the voltage amplifier 50 is controlled to output an excitation voltage to the laser 10 to cause the laser 10 to emit an initial beam 101.

In this embodiment, the excitation voltage refers to a voltage that when the voltage rises to a certain value, the gas in the gas-emitting device is excited to emit light, and this voltage is called the excitation voltage; therefore, the main controller 40 sends a timing pulse to the voltage amplifier 50, so as to control the voltage amplifier 50 by the main controller 40, and when the voltage amplifier 50 receives a signal of the timing pulse, the voltage amplifier 50 is controlled to output an excitation voltage to the laser 10, so that the laser 10 sends an initial light beam 101; optionally, the laser 10 may adopt a semiconductor laser 10, and the semiconductor laser 10 has the characteristics of wide wavelength range, simple manufacture, low cost, easy mass production, and the like, so that the quality of the emitted initial light beam 101 is improved very high, and the overall power consumption can be reduced.

S20, controlling the light-transmitting member 20 to deflect at a predetermined frequency according to the second control signal when the initial light beam 101 is emitted, so that the initial light beam 101 refracts and deflects through the light-transmitting member 20 to form the target light beam.

In this embodiment, the target beam is formed as a multi-line beam, and the first control signal and the second control signal may be performed simultaneously, or the first control signal may be triggered first and then the second control signal may be triggered; when the initial light beam 101 irradiates towards the light-transmitting member 20, the main controller 40 can simultaneously output a second control signal to deflect the light-transmitting member 20 or after the initial light beam 101 irradiates, the main controller 40 outputs the second control signal to control the deflection of the light-transmitting member 20; wherein, the light-transmitting member 20 is a semi-cylindrical lens, and the light-transmitting member 20 deflects around its axial direction by an angle, that is, when the initial light beam 101 irradiates on the light-transmitting member 20, because the position of the laser 10 is not changed, the light-transmitting member 20 rotates around its axial direction to deflect, so that the initial light beam 101 forms a multi-line synchronous irradiation under the refraction deflection effect of the light-transmitting member 20, and the area of the laser beam irradiating on the skin is larger.

The specific implementation manner of step S20 includes sending a power control command to the power controller 60 when the initial light beam 101 is sent out; controlling the relay 301 to be switched on or off according to a predetermined frequency according to the control instruction; when the relay 301 is turned on or off at a predetermined frequency, the light-transmitting member 20 is angularly deflected with the relay 301 at the predetermined frequency.

In this embodiment, 4 relays 301 may be provided, and are respectively close to four corner points of the light-transmitting member 20, when two of the relays 301 are turned on, the other two relays 301 may be controlled to be turned off, so that when two of the relays 301 are turned on, the light-transmitting member 20 deflects towards the direction in which the two relays 301 are turned on, and thus, the main controller 40 controls the relays 301 in a circulating manner, thereby realizing the clockwise and counterclockwise circulating deflection control of the light-transmitting member 20, so that the amount of beams refracted and deflected by the initial beam 101 is more, and the irradiation effect is better; in a preferred embodiment, the predetermined frequency is 2-10 times per second, and the deflection angle may be 25-40 degrees, wherein the predetermined frequency and the deflection angle may be set according to actual requirements, for example, the predetermined frequency may be 3 times per second, 6 times per second, and the deflection angle may be 30 degrees, which is not limited herein.

The multiline laser control method provided by the invention can send out a first control signal and a second control signal when an operation instruction is detected, and control the light-transmitting piece 20 to deflect at a preset frequency according to the second control signal when the initial light beam 101 is sent out, so that the initial light beam 101 is refracted and deflected by the light-transmitting piece 20 to form a target light beam, and when the multiline laser control method is applied to a depilating instrument, the area of the skin irradiated by the laser beam can be larger, and multiline synchronous irradiation can be realized by expanding a light outlet of the depilating instrument, so that the irradiation effect is better, and the depilating efficiency can be improved.
