The laser beauty instrument is a device for burning human skin by using laser spots with controllable energy, thereby removing flaws such as spots on the skin.

An optical shaping system for a laser beauty instrument is disclosed in Chinese patent publication No. CN218181223U, which adopts two rod lenses to shape laser beams, but the price of the two rod lenses is higher, and a large space is needed for fixed installation, so that the production cost of the laser beauty instrument is higher. A novel optical-mechanical system with the Chinese patent publication number of CN208785607U, a back focus optimized optical focusing system with the Chinese patent publication number of CN208026990U, and related technologies are also disclosed, but the systems are complex, which is not beneficial to reducing the production cost.

The utility model provides a laser skin tendering instrument.

In one embodiment of the present utility model, the laser skin tender apparatus as shown in fig. 1 to 6 comprises:

a housing 10;

a power supply 20 provided in the casing 10; and

the laser module 30 comprises a mounting plate 31, an optical waveguide 32 and a laser 33, wherein the optical waveguide 32 is provided with an incident end face 321 and an emergent end face which are opposite, the emergent end face is exposed on the shell 10 and forms a treatment window 322, the treatment window 322 is used for abutting against skin, the mounting plate 31 is arranged on the shell 10 and is concavely formed with an arc face 311 towards one side of the optical waveguide 32, the incident end face 321 corresponds to the arc face 311 and is configured into a convex arc face structure, the laser 33 is electrically connected with the power supply 20, the laser 33 comprises a plurality of laser emergent pieces 331, the plurality of laser emergent pieces 331 are arranged on the arc face 311 at intervals and emit laser beams towards the incident end face 321, and a plurality of laser beams are converged on a convergence point at the outer side of the treatment window 322 after penetrating out of the optical waveguide 32.

According to the technical scheme, the plurality of laser beams emitted by the plurality of laser emitting pieces 331 are converged on one convergence point, so that the laser beams on the convergence point have higher energy, the high-energy laser beams are utilized to generate a thermal effect on the dermis of the skin, the laser energy is absorbed by collagen in the dermis, and the thermal effect of the laser promotes collagen regeneration, so that the aim of increasing skin elasticity is fulfilled. Compared with the use of lenses with higher cost for optical shaping of the laser beam, the technical scheme of the utility model is that the optical waveguide 32 is arranged on the optical path of the laser beam for optical shaping of the laser beam, and the treatment window 322 is formed on the emergent end surface of the optical waveguide 32, so that the energy of the formed light spot after the laser beam is emitted from the treatment window 322 is uniformly distributed and the energy density is higher. The multiple laser beams respectively emit from the arc surfaces and then enter the incident end surface of the convex arc surface structure of the optical waveguide, so that the multiple laser beams can still be converged on one focusing point after passing through the optical waveguide. According to the utility model, a plurality of laser beams are converged at one point through the arc-shaped surface 311, and the uniform light treatment of the laser beams is realized through the optical waveguide 32, so that the requirements of the laser 33 and an optical shaping system on the installation space are reduced, the volume of the laser skin care instrument is reduced, and the production cost of the laser skin care instrument is effectively reduced.

By mounting the laser emitting pieces 331 on the mounting plate 31 having the arc surface 311, and causing the plurality of laser emitting pieces 331 to be arranged at intervals on the arc surface 311 and emit laser beams toward a side away from the arc surface 311, the arc surface 311 converges the plurality of laser beams into one laser beam at a point outside the arc surface 311. To cause the laser beam to emit out of the treatment window 322, the arcuate surface 311 of the mounting plate 31 is recessed toward the treatment window 322 and the arcuate surface 311 is recessed toward the end remote from the mounting window.

Alternatively, the shape of the arc surface 311 is configured as a spherical surface with the center of the spherical surface located at the collection point, and the laser 33 irradiates a laser beam toward the center of the spherical surface. Generally, when the laser 33 is vertically installed on a spherical surface, a laser beam emitted from the laser 33 must pass through the center of the spherical surface, so that when the arc surface 311 is configured as a spherical surface and the laser 33 is installed vertically to the spherical surface, the position of the focus point is easily obtained, and it is convenient to vertically install the laser 33 on the spherical surface. The distance between the focal point and the mounting plate 31 can be controlled by controlling the radius of the sphere at this time. In other embodiments, the arc surface 311 may be configured as an ellipsoid or an arc structure composed of a plurality of stepped surfaces, and the position of the focusing point is adjusted by the orientation of the laser emergent member 331.

Optionally, a plurality of mounting holes are arranged on the arc-shaped surface 311 at intervals, the axis of each mounting hole is perpendicular to the arc-shaped surface 311, and the laser emergent piece 331 is embedded in each mounting hole. The laser emitting member 331 is vertically installed in the arc surface 311 such that the laser beam emitted from the laser emitting member 331 is directed toward the center of the arc surface 311. And the mounting hole with the axis perpendicular to the arc surface 311 is easily punched on the arc surface 311. In another embodiment, the arc surface 311 has no mounting hole, and the laser emitting member 331 is fixed on the arc surface 311 by glue. In other embodiments, the axis of the mounting hole may not be perpendicular to the arc surface 311, and the laser emergent member 331 may flexibly adjust the mounting angle on the arc surface 311 according to the required focusing point position.

In this scheme, the distance between the focusing points and the therapeutic window 322 is set as the irradiation depth, when the instrument is used, the therapeutic window 322 is abutted against the skin surface, and the irradiation depth corresponds to the depth of the light spot formed by shaping and converging the multiple laser beams emitted by the laser emergent piece 331 under the skin, namely the therapeutic depth of the laser skin tendering instrument. Without loss of generality, different irradiation depths have different therapeutic effects. For example, when the irradiation depth is in the range of 1.5mm to 4.5mm, the laser has a skin tendering effect, and when the irradiation depth is in the range of 4.5mm to 20mm, the laser has a fat reducing effect on the human body.

As shown in fig. 2, alternatively, the laser emitting member 331 is configured as laser beads 331a, a plurality of which are embedded in the mounting hole, and emit laser beams toward the incident end face. It can be understood that, assuming that the energy required for generating the thermal effect is constant, the more the number of the laser beads 31a is, the smaller the power requirement is allocated to each laser bead 331a, that is, the cost of the laser skin care apparatus can be reduced by using a plurality of low-power laser beads 331a to replace the high-power laser beads 331 a; and after a lot of experiments, the scheme of the utility model finds that when the treatment effect of the high-power laser lamp beads 331a is consistent with the utility model, the power of the plurality of low-power laser lamp beads 331a used in the utility model is smaller than the power of the high-power laser lamp beads 331a after being added, so that the energy consumed by the plurality of low-power laser lamp beads 331a used in the scheme is lower than the energy consumed by one high-power laser lamp bead 331 a.

As shown in fig. 6, optionally, the laser further includes a laser light source 333 and a beam splitter 332, where the laser emitting element is configured as an optical fiber guide 331b, the optical fiber guide 331b extends along the axis of the mounting hole, the laser light source 333 is configured to emit laser light, the laser light source 333, the beam splitter 332, the arc surface 311, and the incident end surface 321 are sequentially arranged along the emission direction of the laser light, and the beam splitter 332 is configured to split one laser beam emitted from the laser light source 333 into multiple parallel laser beams, and the multiple laser beams correspondingly irradiate the multiple optical fiber guides 331b. In this embodiment, the plurality of optical fiber guides 331b are embedded in the mounting hole, so that the laser light passing through the optical fiber guides 331b can be emitted toward the incident end surface and focused on a focusing point outside the treatment window 322. Thus, when the laser light source 333 fails, only one laser light source 333 needs to be removed, which is convenient for maintenance. The laser light source 333 is configured as a high-power laser lamp, and is capable of emitting a high-energy laser beam.

Optionally, the laser module 30 further includes an irradiation depth adjusting member 40, and the mounting plate 31 is movably connected to the casing 10 and is driven by the irradiation depth adjusting member 40 to approach or separate from the treatment window 322 so as to adjust the irradiation depth. In this embodiment, the irradiation depth is adjusted by moving the distance between the mounting plate 31 and the treatment window 322, so as to realize the conversion of different treatment effects when the laser skin tenderer works. One end of the irradiation depth adjusting member 40 is connected to the casing 10, and the other end is connected to the mounting plate 31 such that the mounting plate 31 can move on the casing 10. In this embodiment, the irradiation depth may be selected to be 1.5mm to 20mm. Thus, the movable range of the mounting plate is 0mm to 18.5mm. In other embodiments, the irradiation depth adjusting member 40 may not be provided, and the laser modules 30 may be provided in plurality and replaceable, each laser module 30 having a different irradiation depth therebetween.

Alternatively, the irradiation depth adjusting member 40 includes a linear motor 41 and a guide member 42, and the mounting plate 31 drives a push rod connected to the linear motor 41 and is slidably connected to the guide member 42 in a direction approaching or separating from the treatment window 322. I.e. the irradiation depth adjusting member 40 is a ball screw. In other embodiments, the irradiation depth adjusting member 40 includes a driving motor, a guide wheel at an output end of the driving motor, a guide rail, a roller clamped in the guide rail, and a synchronous belt connecting the guide wheel and the roller, wherein the driving motor drives the guide wheel to rotate, and the roller in the guide rail is driven to rotate by the synchronous belt connected with the guide wheel, so that the roller drives the driving motor to move on the guide rail.

Optionally, the laser skin care apparatus further includes a cooling module 50 and a cooling fan 60 disposed on the casing 10, the casing 10 is provided with a cooling channel 11 corresponding to the cooling fan 60, the cooling module 50 has a cold end and a hot end, the cold end is connected to a side surface of the optical waveguide 32, and the hot end is disposed in the cooling channel 11. Because the laser heats the skin when acting on the skin of the human body, in order to prevent the user from being burnt by the laser beam when using the laser skin tendering instrument, the skin of the human body needs to be cooled in time. The cold end of the refrigeration module 50 is connected with the side surface of the optical waveguide 32, so that the cold end cools the optical waveguide 32, and the cooled optical waveguide 32 is contacted with the skin of the human body through the treatment window 322, so that the temperature of the skin of the human body which is being warmed is reduced. Since the cooling module 50 can heat the hot end when the cold end is cooled, the hot end is arranged in the heat dissipation channel 11, which is helpful for timely reducing the internal temperature of the laser skin tender instrument during operation. In other embodiments, the refrigeration module 50 and the cooling fan 60 may not be provided, and the user may avoid skin burn by intermittently using the laser skin tenderer to naturally cool the skin.

Optionally, the refrigeration module 50 includes a semiconductor refrigeration sheet 51 and a heat transmitter 52 connected, a cold end is formed on the semiconductor refrigeration sheet 51, a hot end is formed on the heat transmitter 52, the semiconductor refrigeration sheet 51 is electrically connected with the power supply 20, the laser skin care apparatus further includes a heat dissipation fin 312 disposed on the heat dissipation channel 11, and the heat transmitter 52 is connected with the heat dissipation fin 312. Specifically, the cooling surface of the semiconductor cooling plate 51 is closely attached to the side surface of the optical waveguide 32, the heating surface of the semiconductor cooling plate 51 is closely attached to the heat transmitter 52, the semiconductor cooling plate 51 directly cools the optical waveguide 32, the heat transmitter 52 adopts a heat pipe, the heat of the semiconductor cooling plate 51 is rapidly transmitted to the heat dissipation fins 312, and the heat dissipation fins 312 exchange heat with air, so that the heat dissipation system is effectively simplified. In other embodiments, the refrigeration module 50 may also be cooled by condensate.

Optionally, the material of the optical waveguide 32 is configured as sapphire. In this embodiment, the optical waveguide 32 is made of sapphire, which is chemically resistant, high temperature resistant, high in hardness and better in freezing point effect. The semiconductor refrigerating sheet 51 is abutted against the side surface of the sapphire optical waveguide 32, and directly cools the sapphire, so that the temperature of the treatment window 322 is rapidly reduced, and the skin can be effectively cooled. In addition, the end face of the sapphire optical waveguide 32 is directly used as a treatment window 322, and the transmittance of a laser light path is as high as more than 90%. The sapphire is used as the optical waveguide 32 for optical path shaping, so that the optical path is simple and the light spots are uniform. Of course, in other embodiments, the material of the optical waveguide 32 may be configured as a material with thermal conductivity and light transmissibility, such as glass, and the laser emitting element 331 is directly adjacent to the glass treatment window 322, so that no light homogenizing and shaping of the optical waveguide 32 is required.

Optionally, the mounting plate 31 is further connected to a heat dissipating fin 312, and the material of the mounting plate 31 is configured as metal. The metal has good heat conduction property, and can transfer heat generated during operation of the laser emitting member 331 from the mounting plate 31 to the heat radiating fins 312, so as to perform good heat radiation effect on the laser 33. Of course, in other embodiments, the mounting plate 31 may be configured to dissipate heat without the heat dissipation fins 312 being connected thereto, and instead may have a structure extending into the heat dissipation channel 11; alternatively, the mounting plate 31 may be made of other materials, such as high thermal conductive plastic, graphite, and the like.

Alternatively, the laser beam wavelength of the laser 33 may be in the range of 610nm to 2000nm. The laser beam wavelength in the range can effectively play a role in the treatment of the human skin, such as cosmetology. Further alternatively, the laser beam wavelength of the laser 33 may take a value ranging from 630nm to 830nm, and the laser beam wavelength within this range is easy to achieve and consumes less energy.
