Detailed implementation manners

[0041] The technical solution of the present application will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit the implementation manner of this application.

[0043] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the meaning of "a plurality" is two or more. The terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0044] First, the embodiment of the present application provides a laser beauty module, which can be applied to beauty equipment and stimulate the regeneration of skin collagen by emitting a laser beam of a certain wavelength to achieve the purpose of beauty or treatment. Please refer to Figure 1 , the laser beauty module includes a laser component 10 and an optical lens component 20. Among them, the laser component 10 is used to generate a laser beam; the optical lens component 20 is used to adjust the laser beam into a laser dot matrix with a certain density and size.

[0045] Specifically, the laser assembly 10 includes a laser 11 and a driving module 12. The laser 11 is preferably a semiconductor laser, and its wavelength is not limited. For example, the laser 11 can be a laser with a wavelength of 1440 nm to provide functions such as removing acne marks and reducing wrinkles; the laser 11 can also be a laser with a wavelength of 650 nm to promote cell metabolism and accelerate blood circulation; the laser 11 can also be a laser of other wavelength types, and corresponding designs can be made according to the main function. One or more lasers 11 can be provided to emit one or multiple laser beams.

[0046] The driving module 12 is electrically connected to the laser 11 and is used to control the pulse width and output level of the laser 11. The pulse width determines the time scanning frequency of the dot matrix laser. By adjusting the pulse width, the time when the dot matrix laser irradiates the user's skin can be correspondingly adjusted to reduce the user's pain. Different output levels correspond to different powers at which the laser 11 operates. By adjusting the output level of the laser 11, the laser dot matrix can be made to move quickly or slowly on the skin surface during beauty operations to obtain the same or similar physical sensations in accordance with the user's habits, thereby improving the user experience.

[0047] The optical lens assembly 20 includes an astigmatic lens 21, a condenser lens 22, a collimating lens 23, and a focusing lens 24. The astigmatic lens 21, the condenser lens 22, the collimating lens 23, and the focusing lens 24 are arranged in sequence on the optical axis along the light-emitting direction of the laser. Among them, the astigmatic lens 21 is correspondingly arranged with the laser 11 and is used to expand a beam or multiple beams of laser emitted by the laser 11 into a scattered surface laser; the condenser lens 22 is correspondingly arranged with the astigmatic lens 21 and is used to control the laser passing through the astigmatic lens 21 within a certain emission range and emission angle so that it irradiates the collimating lens 23; the collimating lens 23 is correspondingly arranged with the condenser lens 22 and is used to convert the laser at different angles passing through the condenser lens 22 into multiple parallel and equally spaced dot matrix lasers; the focusing lens 24 is correspondingly arranged with the collimating lens 23 and is used to adjust the spot size of the dot matrix laser.

[0048] Specifically, the astigmatic lens 21 can be a biconcave lens, and the laser expansion angle can be adjusted by setting the curvatures on both sides of the astigmatic lens 21.

[0049] The condenser lens 22 can be a plano-convex lens, so that the laser passing through the astigmatic lens 21 is emitted from the condenser lens 22 at a preset angle and range, and the emission range and emission angle of the scattered surface laser can be adjusted by setting the curvature on one side of the condenser lens 22.

[0050] Please refer to Figure 2The light-rectifying lens 23 has a light incident surface and a light emitting surface, wherein a plurality of incident portions 231 for allowing laser light to pass through are provided on the light incident surface, and a plurality of light-rectifying portions 232 corresponding to the incident portions 231 are provided on the light emitting surface. Laser light can only be incident on the light-rectifying lens 23 from the incident portions 231. The plurality of incident portions 231 can separate the scattered laser light to form a plurality of beams. When each laser beam is incident on the corresponding light-rectifying portion 232, refraction occurs, so that the laser light is emitted at a preset angle. The plurality of incident portions 231 cooperate with the light-rectifying portions 232 corresponding thereto to form a plurality of parallel dot matrix laser beams. Preferably, a reflective member 233 is attached to the light incident surface, and the reflective member 233 may be a reflective sticker. The area on the light incident surface not covered by the reflective member forms an incident portion 231, for example, a plurality of incident portions 231 in the form of small holes are formed. In this way, when the laser is incident on the reflective sticker, it is blocked to form diffusion and cannot pass through the light-correcting lens 23. When the laser is incident on the area on the light incident surface not covered by the reflective sticker, that is, the incident portion 231, it can smoothly pass through the light incident surface and then be emitted from the light-correcting portion 232. The light-correcting portion 232 may be a convex lens-like structure convexly arranged on the light-exiting surface, or a concave lens-like structure concavely arranged on the light-exiting surface, or an irregular structure, etc. Correspondingly, the incident portion 231 may be located at the focal position of the light-correcting portion 232 of the convex lens structure, or the laser light path incident through the incident portion 231 passes through the focal position of the light-correcting portion 232 of the concave lens structure, etc. The specific structure may be designed accordingly according to the actual situation, and it is only necessary to meet the requirement that the dot matrix lasers formed by the plurality of light-correcting portions 232 are emitted in parallel.

[0051] The focusing lens 24 may be a convex lens or a concave lens. By adjusting the distance between the focusing lens 24 and the light-correcting lens 23, the spot size of the dot-matrix laser formed by the light-correcting lens 23 may be further adjusted to reach a preset size. Preferably, the focusing lens 24 may be fixedly arranged so that the dot-matrix laser is emitted with a preset spot size, or may be movable relative to the light-correcting lens 23 so that the user can actively adjust the spot size, which is not limited here.

[0052] In this way, by setting the arrangement density of the whole light part 232, the density of the fractional laser can be adjusted. For example, a dense fractional array can be set to increase the cosmetic treatment area, so that more cells in the skin absorb the laser, and the cosmetic treatment effect is better. By setting the focusing lens 24, the spot size of the fractional laser can be controlled. For example, a very small spot can be formed to achieve a minimally invasive and non-invasive effect, and each fractional laser beam has greater energy, and the user experience is better.

[0053] Preferably, multiple light-correcting parts 231 can be arranged in a uniform array to form parallel and equally spaced dot matrix lasers, so that the energy of the dot matrix lasers irradiated on the skin is consistent, thereby improving the uniformity of the cosmetic treatment; the spot diameter formed by each beam of dot matrix laser obtained through the focusing lens 24 is preferably 50-150um.

[0054] Furthermore, a condenser aluminum sheet may be provided on the astigmatic lens 21 and / or the condenser lens 22. The condenser aluminum sheet is wrapped around a partial surface of the astigmatic lens 21 and / or the condenser lens 22. Since both the astigmatic lens 21 and the condenser lens 22 are lenses, by wrapping the condenser aluminum sheet around the peripheral surfaces of the astigmatic lens 21 and the condenser lens 22, the light path is blocked and reflected when it hits the condenser aluminum sheet, and will not be directly emitted, thereby reducing the optical path loss through the astigmatic lens 21 and the condenser lens 22. At the same time, the condenser aluminum sheet can serve as a support structure for the astigmatic lens 21 and the condenser lens 22, facilitating the installation and fixation of the astigmatic lens 21 and the condenser lens 22.

[0055] In addition, an embodiment of the present application further provides a laser beauty device for home laser beauty treatment. Please refer to Figure 3 FIG., the laser beauty device includes the aforementioned laser beauty module, and further includes a housing, a main control module 30, a power supply component 40, a refrigeration component 50, a heat dissipation component 60, an attachment component 70, and an interaction component 80.

[0056] Among them, the housing is the outer shell of the laser beauty device. The housing can be made of, but not limited to, a plastic housing, a fiberglass housing, or a metal housing, etc., for the user to hold and operate the laser beauty device. An optical outlet is provided on the housing. The optical outlet is used for the dot matrix laser formed by the laser beauty module to be emitted, and the dot matrix laser is irradiated onto the skin area, thereby achieving the effect of laser beauty. The main control module 30 is disposed inside the housing and can be an integrated circuit board or an integrated chip, which is used to send control signals to each component to control the start and stop of each electronic component.

[0057] The power supply assembly 40 is disposed inside the housing and includes a storage battery 41, a power control module 42, and a charging protection module 43. Among them, the storage battery 41 can be a battery or a battery pack made of various materials such as lithium batteries and lead-acid batteries, and is used to provide power for the operation of the laser beauty device. The power control module 42 can be electrically connected to the main control module 30, the laser assembly 10, the refrigeration assembly 50, and the heat dissipation module 60, and controls the output voltage and output path of the storage battery 41 through circuit and chip design. There are data communication and power transmission functions between the power control module 42 and the main control module 30. The working voltages required by each electronic component may be different, but the voltage required for the main control module 30 to start is generally a standard voltage. The power control module 42 can output a standard voltage to the main control module 30 to power on the main control module 30. The main control module 30 sends a control signal to the power control module 42, and the power control module 42 performs voltage conversion processing on the voltage output by the storage battery 41 according to the control signal and then outputs the working voltage to the target component. The charging protection module 43 is electrically connected to the power control module 42 to provide protection for the input of the external power supply or the charging process, preventing phenomena such as overcurrent, overvoltage, static electricity, and surge. The charging protection module 43 can implement a step-down rectification function through an internal chip. For example, the voltage of the external AC power supply is reduced to a first voltage through a voltage transformation chip, and the alternating current of the first voltage is processed into direct current of the battery charging voltage through a rectification step-down chip and output to the storage battery 41 to charge the storage battery 41. It should be noted that in other embodiments, the storage battery 41 may not be provided, and power can be directly connected to an external power supply to provide power for the operation of the laser beauty device.

[0058] The refrigeration component 50 is disposed inside the housing and includes a first thermoelectric cooler 51, a refrigeration control module 52, and a cooler heat sink 53. Since the threshold current and output optical power of the laser 11 are restricted by the operating temperature, temperature changes will affect the emission wavelength and mode characteristics of the laser 11. The refrigeration component 50 is used to provide a good heat dissipation and constant temperature environment to ensure the stable operation of the laser 11. Among them, the first thermoelectric cooler 51 realizes heating or cooling of the constant temperature environment. When a direct current passes through it, one end absorbs heat and the other end releases heat. Its heating, cooling, and working efficiency are determined by the direction and magnitude of the current. Multiple first thermoelectric coolers 51 can be provided and are all attached to the laser 11. The working temperature of the laser 11 is controlled by the heat absorption or heat release of the first thermoelectric cooler 51. The refrigeration control module 52 is electrically connected to the first thermoelectric cooler 51, and the direction and magnitude of the current flowing through the first thermoelectric cooler 51 can be controlled through the internal circuit design, thereby controlling the working state of the first thermoelectric cooler 51. The cooler heat sink 53 is attached to the first thermoelectric cooler 51 and is used to dissipate heat from the first thermoelectric cooler 51 to improve the temperature control effect of the first thermoelectric cooler 51 and extend the service life of the first thermoelectric cooler 51. The cooler heat sink 53 can be a fin structure. After the heat of the first thermoelectric cooler 51 is transferred to the cooler heat sink 53, heat exchange with air is carried out for heat dissipation. The material of the cooler heat sink 53 can be selected from common high thermal conductivity metals such as copper, aluminum, and ceramics.

[0059] The heat dissipation component 60 is disposed inside the housing and includes a heat conduction member 61 and a fan 62. The heat dissipation component 60 is used for the overall heat dissipation of the laser beauty device, specifically mainly for the heat dissipation of the laser 11 and the cooler heat sink 53. Among them, the heat conduction member 61 can be attached to the laser 11 to conduct the heat generated by the laser 11 to the heat conduction member 61. The heat conduction member 61 can also be selected from common high thermal conductivity metals such as copper, aluminum, and ceramics; the fan 62 is used to generate an air flow, and the air flow can carry the heat of the heat conduction member 61 and the cooler heat sink 53 out of the housing to achieve the heat dissipation function, further improving the temperature control effect on the laser 11, and thus improving the working stability of the laser 11.

[0060] The attachment component 70 includes a sapphire lens 71 and a second semiconductor refrigerating sheet 72. The sapphire lens 71 is arranged at the light outlet of the housing and is used to directly contact the user's skin. By selecting sapphire material with strong ice feeling, it can reduce the burning sensation when contacting the user's skin, not hurt the skin. At the same time, the sapphire has a large hardness, which can further reduce the daily wear of the contact surface with the skin. The second semiconductor refrigerating sheet 72 is arranged in the housing. The second semiconductor refrigerating sheet 72 has a cold end surface for absorbing heat and refrigerating. The cold end surface is attached to the sapphire lens 71, and the cold flow generated by the cold end surface can be transmitted to the sapphire lens 71 to cool the sapphire lens 71, so that there is no burning sensation when the sapphire lens 71 contacts the skin, and at the same time, it can play an analgesic role on the skin.

[0061] The interaction component 80 is used for human-computer interaction and can improve the user experience. The interaction component 80 can specifically include components such as buttons, indicator lights, screens, vibration motors, buzzers, speakers, etc. Each component is electrically connected to the main control module 30. For example, the working gear of the laser 11 can be controlled by operating the button; the working gear or the power of the energy storage battery 41 can be viewed through the indicator light or the screen; the user's operations such as adjusting the gear can be feedback through the vibration motor, buzzer or speaker, thereby improving the user experience.

[0062] In summary, for the laser beauty module and the laser beauty instrument of the embodiment of the present application, multiple parallel and equally spaced dot matrix lasers are formed through the cooperation between the astigmatic lens 21, the condenser lens 22, the light shaping lens 23 and the focusing lens 24 of the optical lens assembly 20; the spot density of the dot matrix laser can be adjusted by setting the arrangement density of the light shaping part 232. For example, a dense dot matrix is set to increase the beauty treatment area, so that more cells on the skin absorb the laser, and the beauty treatment effect is better; the spot size of the dot matrix laser can be controlled by setting the focusing lens 24. For example, an extremely small spot can be formed to achieve the effect of minimally invasive and non-invasive, and the energy of each dot matrix laser is greater, and the user experience is better.

[0063] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the element.

[0064] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
