Optionally, with continued reference to fig. 1, the laser beauty treatment apparatus 10 may further comprise: an optical lens 600; the housing 100 may include a light-transmissive opening 110; the vertical projection of the plurality of laser chips 300 on the substrate 200 has an overlap with the vertical projection of the light-transmitting opening 110 on the substrate 200; the optical lens 600 is arranged at the position of the light-transmitting opening 110, and the vertical projection of the plurality of laser chips 300 on the substrate 200 is positioned in the vertical projection of the optical lens 600 on the substrate 200; the optical lens 600 is used to change the transmission direction of the laser signal emitted from each laser chip 300.

As shown in fig. 1 and 2, a certain interval is inevitably present between two adjacent laser chips 300, and since the laser signal has a high directivity during transmission, a certain gap may be present between two laser signals of two adjacent laser chips 300, so that when the laser signal reaches the skin surface 20, a hollow area that is not irradiated may be present, and the cosmetic effect is affected. To avoid the above problem, the embodiment of the present invention provides the optical lens 600 on the light emitting side of the laser chip 300.

On the basis of the above embodiments, the embodiment of the present invention further provides another control method for a laser beauty instrument, and fig. 7 is a flowchart illustrating the control method for another laser beauty instrument according to the embodiment of the present invention. As shown in fig. 7, the method for controlling a laser beauty instrument further includes:

s210, the control module receives a mode selection instruction, wherein the mode selection instruction comprises an area scanning mode instruction.

It can be understood that the laser beauty mode can be divided into a plurality of beauty items, such as an area scanning item, a scanning speed item, a laser intensity item, a laser model item, etc.; the laser model item can be understood as the selectable laser wavelength, for example, the laser depilation can be selected to be 808nm, and the laser skin-tendering can be selected to be 1064 nm; the laser intensity item can be selected laser pulse width and current magnitude, for example, the laser pulse width can be 10ms-600ms, and the current magnitude can be 5A-100A; the scanning speed item can be understood as the switching speed among a plurality of laser array areas in the scanning process, and can also include the irradiation time of the laser chip in each laser array area, and the like; the area scanning item can be understood as a preset combined mode of a plurality of laser array areas. The scanning area items can comprise various area scanning mode instructions, the scanning speed items can comprise various scanning speed mode instructions, the laser intensity items can comprise various laser intensity mode instructions, the laser model items can comprise various laser signal mode instructions, namely, a user can combine various beauty treatment items according to actual requirements, and the control module can receive various mode selection instructions.

And S230, each driving module drives the laser chips electrically connected with the driving module to emit laser signals in a preset sequence.

The particular region scan pattern command corresponds to a particular partition combination pattern. When the beauty treatment item selected by the user comprises a scanning area item, the mode selection instruction received by the control module comprises an area scanning mode instruction, namely, a specific subarea combination mode can be determined. For example, as shown in table 1, the laser array region of the group combination mode may be one laser array region, or may include a plurality of different laser array regions. The control module can preset the scanning sequence of different laser array areas according to a specific mode selection instruction, and sends control signals to the driving modules corresponding to the selected laser array areas according to the preset sequence, so that the sequential lighting of the laser chips of the selected laser array areas is realized. In addition, the scanning speed item can be matched, the appropriate switching speed and the irradiation time of the laser chip in each laser array area are selected, and the partition sequential scanning of different laser array areas is realized.

S240, judging whether the control module receives a mode switching instruction or a shutdown instruction; if yes, go to S250; if not, the process returns to the step S220.

And S250, executing a mode switching instruction or shutting down.

The control module can send control signals to each driving module according to a preset sequence according to the region scanning selection instruction so as to control the partition scanning of different laser array regions in sequence; the control module receives a mode switching instruction or a shutdown instruction, and the control module switches to a next mode selection instruction or executes the shutdown instruction; when the control module does not receive the mode switching instruction or the shutdown instruction, the control module repeats the preset sequence and sends control signals to each driving module according to the preset sequence again so as to realize the subarea scanning and the multiple scanning of different laser array areas.

Illustratively, referring to table 1 and fig. 2, when the user selects the mode 123, the preset sequence includes a first time period, a second time period, and a third time period that are chronologically set. In a first time period, the control module sends a control signal to the driving module corresponding to the first laser array region 211, so that the laser chip 300 in the first laser array region 211 firstly generates a laser signal; in a second time period, the control module sends a control signal to the driving module corresponding to the second laser array area 212, and stops sending the control signal to the driving module corresponding to the first laser array area 211, so that the laser chip 300 in the second laser array area 212 generates a laser signal; in a third time period, the control module sends a control signal to the driving module corresponding to the third laser array area 213, stops sending the control signal to the driving module corresponding to the second laser array area 212, and generates a laser signal by the laser chip 300 in the third laser array area 213; when the switching instruction or the shutdown instruction is not received, the control module repeatedly executes the preset sequence, that is, the control signal … … is sent to the driving module corresponding to the first laser array region 211 again until the control module receives the mode switching instruction or the shutdown instruction, which needs to be described.

In order to achieve a cosmetic effect, a user usually irradiates the same position with laser for a long time, and often feels pain, so that the user experience is poor.
