[0003] In the prior art, laser beauty devices change the focusing characteristics of the laser to turn the laser point into a light spot, use fast-axis and slow-axis compression lenses to focus the light spot, and change the angle of the reflector to achieve scanning.

[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] This embodiment provides a laser beauty device and a laser scanning device, such as Figure 1-Figure 3As shown, the laser beauty device includes a shell and a laser scanning device provided in this embodiment. Specifically, the shell includes an upper shell 10 and a lower shell 20, and the upper shell 10 and the lower shell 20 are detachably snap-fitted. The upper shell 10 and the lower shell 20 surround an inner cavity of the shell, and the laser scanning device is arranged in the inner cavity of the shell. The lower shell 20 is provided with a light outlet 201 connected to the inner cavity of the shell, and the emission light emitted by the laser scanning device can be emitted from the light outlet 201 to act on the position to be treated. It can be understood that the position to be treated can be but is not limited to the surface skin of the human body.

[0049] like Figure 4-Figure 8 As shown, the laser scanning device provided in this embodiment includes a laser 1, a mirror assembly 2 and a drive assembly 3. Among them, the laser 1 is used to emit laser light, the mirror assembly 2 is spaced apart from the laser 1, the reflective surface of the mirror assembly 2 is arranged opposite to the laser 1, and the mirror assembly 2 can reflect the emitted light emitted by the laser 1 to the position to be processed to achieve laser beauty. The drive assembly 3 includes a drive member 31 and a cam transmission structure, and the output end of the drive member 31 is connected to the mirror assembly 2 through the cam transmission structure. In this embodiment, the drive member 31 is preferably a drive motor, and its structure and principle are all prior art, which will not be repeated here. The output end of the drive member 31 can drive the mirror assembly 2 to move back and forth along the extension direction parallel to the emitted light of the laser 1, so that the reflected light of the mirror assembly 2 is reciprocated and scanned within a preset path. Figure 7 A path diagram showing the emitted light of the laser when the laser scanning device provided by the embodiment of the utility model is in the first working position; Figure 8 A path diagram of the laser light emitted when the laser scanning device provided by an embodiment of the utility model is in the second working position is shown. The arrow in the figure indicates the path direction of the light emitted by the laser 1. The reflector assembly 2 can change the path of the light emitted by the laser 1. Moving the reflector assembly 2 can make the reflected light scan back and forth between the first working position and the second working position.

[0050] In this embodiment, the reflected light of the reflector assembly 2 can be emitted from the light outlet 201, and the length of the light outlet 201 is not less than the length of the preset path. In other words, the moving distance of the reflector assembly 2 is related to the length of the light outlet 201. The longer the length of the light outlet 201 is, the greater the movable distance of the reflector assembly 2 is, the larger the area scanned by the reflected light in a single scan is, the larger the actual effective area of ​​the emitted light is, and the better the cosmetic effect is.

[0051] That is to say, compared with the laser beauty instrument that emits light in the entire window area, the laser beauty device provided in this embodiment realizes the scanning process by moving the reflector assembly 2, that is, a laser 1 with lower power can be used to achieve a larger scanning area, thereby increasing the actual effective area of ​​the laser, effectively improving the beauty efficiency and user experience.

[0052] Compared with the laser beauty device in the prior art that uses a moving laser to achieve laser scanning, the laser is generally fixed together with the heat dissipation device, and the movement of the laser needs to drive more structures to move at the same time, so the structural space required to be reserved inside the laser beauty device is large, and the drive motor also needs a larger torque to achieve driving, resulting in a waste of resources. The laser beauty device provided in this embodiment uses a cam transmission structure to achieve the movement of the reflector assembly 2, and the overall structure is simple, which helps to achieve the overall miniaturization of the device and improve portability.

[0053] Compared with the laser beauty device in the prior art that rotates the reflector to achieve laser scanning, the reflector usually only needs to rotate a small angle to achieve the scanning of the area by the beam, which is greatly affected by the assembly accuracy and movement accuracy. In this embodiment, the moving distance of the reflector assembly 2 can be designed by the cam transmission structure, and the intensity affected by the installation and movement accuracy is small.

[0054] Continue to refer to Figure 3 and Figure 5 The laser scanning device further comprises a mounting frame 4, on which the laser 1 and the reflector assembly 2 are arranged at intervals along the extending direction of the emitted light, the fixed end of the driving member 31 is fixedly connected to the mounting frame 4, and the output end of the driving member 31 is transmission-connected to the reflector assembly 2 through a cam transmission structure. The mounting frame 4 is arranged in the inner cavity of the housing and serves as a mounting carrier for the fixed installation of other components to improve the integrity and compactness of the laser scanning device.

[0055] Specifically, Figure 4 and Figure 5As shown, the cam transmission structure includes a transmission wheel 32, a guide rod 33 and a sliding member 34. The guide rod 33 is parallel to the extending direction of the emitted light, a sliding hole is provided on the mounting frame 4, the guide rod 33 is slidably penetrated through the sliding hole, and the sliding member 34 is respectively fixedly connected to the reflector assembly 2 and the guide rod 33. The transmission wheel 32 is connected to the output end of the driving member 31, a slider 321 is provided on the transmission wheel 32, the height direction of the slider 321 is parallel to the axial direction of the transmission wheel 32, a slide groove 341 is provided on the sliding member 34, the extending direction of the slide groove 341 forms an angle with the length direction of the guide rod 33, and the slider 321 is slidably arranged in the slide groove 341. When the output end of the driving member 31 drives the transmission wheel 32 to rotate, the slider 321 on the transmission wheel 32 slides in the slide groove 341, and drives the slider 34 and the guide rod 33 to slide forward and backward along the length direction of the sliding hole, thereby driving the reflector assembly 2 arranged on the slider 34 to move. In this embodiment, since the contact area between the slide 34 and the guide rod 33 is larger than the contact area between the guide rod 33 and the mounting frame 4, the slide 34 is easily stuck when it is subjected to force on one side when it moves. Therefore, two guide rods 33 are provided, and the two guide rods 33 are parallel, spaced and slidably provided on the mounting frame 4 to ensure the smooth movement of the guide rod 33, the slide 34 and the reflector assembly 2. During the rotation of the output end of the driving member 31, the laser 1 is continuously powered on to emit a line beam laser, so as to ensure that the reflector assembly 2 reflects the laser and performs scanning during the movement.

[0056] In this embodiment, if Figure 3 and Figure 4 As shown, the cam transmission structure is placed on the side of the inner cavity of the housing, which will not affect the optical system. At the same time, the slider 321 on the transmission wheel 32 is a cylindrical structure, and the slide groove 341 on the sliding member 34 is a long strip structure. The processing of the slider 321 and the slide groove 341 is simple, which is conducive to reducing the manufacturing cost. Furthermore, the relative movement of the slider 321 in the slide groove 341 is rolling, the friction force of rolling friction is small, and the wear during use is small, which can effectively increase the service life of the device.

[0057] It can be understood that the installation position of the slider 321 on the transmission wheel 32 determines the reciprocating distance of the slider 34 on the guide rod 33. When the slider 321 is set at the edge of the transmission wheel 32, the transmission wheel 32 rotates to drive the slider 34 to move, and the maximum reciprocating distance is equal to the diameter of the transmission wheel 32 minus the diameter of the slider 321. The closer the installation position of the slider 321 is to the center of the transmission wheel 32, the smaller the reciprocating distance of the slider 34.

[0058] Optionally, in this embodiment, the sliding member 34 is L-shaped, including a sliding portion and a connecting portion that are fixedly connected. The sliding portion is slidably sleeved outside the guide rod 33, and the sliding groove 341 is opened on the connecting portion, and the extending direction of the sliding groove 341 is perpendicular to the length direction of the guide rod 33.

[0059] Continue to refer to Figure 6-Figure 8 , the reflector assembly 2 includes a reflector 21 and a lens 22 arranged at intervals, the lens 22 is arranged between the laser 1 and the reflector 21, and the emitted light of the laser 1 is irradiated on the reflective surface of the reflector 21 after passing through the lens 22. The lens 22 can be used to adjust the emitted light emitted by the laser 1 so that the emitted light of the laser 1 meets the requirements of the incident light of the reflector 21. Of course, the lens 22 is not necessarily provided. If the emitted light of the laser 1 is directly incident on the reflector 21 and can meet the requirements of nursing and treatment after reflection, then the lens 22 is not required.

[0060] Alternatively, if Figure 2-Figure 5 As shown, the laser scanning device also includes a light output component 5, which includes a dielectric waveguide 51 and a light output mirror 52. The reflected light of the reflector assembly 2 passes through the dielectric waveguide 51 and the light output mirror 52 in sequence and acts on the position to be processed. The dielectric waveguide 51 and the light output mirror 52 can make the reflected light more uniform after multiple reflections therein. In this embodiment, the light output mirror 52 will be in close contact with the skin of the human body during use, and the light output mirror 52 can quickly cool down to reduce the burning sensation caused by the light and ensure comfort.

[0061] Preferably, the light-emitting mirror 52 is a sapphire mirror. Of course, the light-emitting mirror 52 can also be made of other crystal materials, such as K9 glass and crystal glass, etc., as long as the material satisfies the requirements of light-transmitting crystals.

[0062] Optionally, continue to refer to Figure 2-Figure 5 The laser scanning device further includes a heat dissipation component 6, which includes a fan 61, and the air outlet of the fan 61 faces the laser 1. The fan 61 cools the internal space of the housing, the laser 1, the drive component 3, etc. The fan 61 can be a centrifugal fan, an axial flow fan, a mixed flow fan, or a cross flow fan, which is not limited here.

[0063] Specifically, the heat dissipation assembly 6 also includes a heat dissipation block 62, which is thermally connected to the laser 1, and the air outlet of the fan 61 faces the heat dissipation block 62. The heat generated by the laser 1 can be transferred to the heat dissipation block 62 and dissipated by the fan 61, thereby achieving a cooling effect.

[0064] More specifically, the heat dissipation assembly 6 further includes a cooling fin 53. The cooling surface of the cooling fin 53 is thermally connected to the light output mirror 52, and the thermally conductive surface of the cooling fin 53 is thermally connected to the heat dissipation block 62. The cooling fin 53 may be a TEC semiconductor temperature difference cooling fin. During the operation of the cooling fin 53, as long as there is a temperature difference between the cold end of the cooling fin 53 and the hot end of the cooling fin 53, heat is continuously transferred, and the heat is transferred to the hot end of the cooling fin 53 and dissipated through the heat dissipation block 62.

[0065] More specifically, the heat dissipation assembly 6 further includes a heat conductive member 54. The heat conductive member 54 is disposed between the cooling surface of the cooling plate 53 and the light output mirror 52. The upper and lower end surfaces of the heat conductive member 54 are thermally coupled with the cold end of the cooling plate 53 and the light output mirror 52, respectively. The heat on the light output mirror 52 can be transferred to the cooling plate 53 through the heat conductive member 54, and then transferred to the heat dissipation block 62 for heat dissipation. Optionally, the heat conductive member 54 can be a sheet-shaped thermal pad or a sheet-shaped thermal conductive silicone grease.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
