Technical Field

[0001] The present invention relates to the technical field of laser treatment equipment, and in particular to a household laser freckle removal and anti-aging beauty instrument. Background Art

[0002] With the rapid development of society, people are under increasing pressure in life. As they age and stay up late to work overtime, the skin on their faces will become more and more loose. Coupled with unhealthy diet and damage from the environment (ultraviolet rays, air pollution, etc.), the skin ages. Aging skin is prone to symptoms such as nasolabial folds, cysts at the corners of the mouth, unclear jaw lines, double chins, and drooping apple muscles.

[0003] The most common home skin rejuvenation device on the market is the IPL photon skin rejuvenation device. (IPL) Intense Pulsed Light or Pulsed Intense Light is a broad-spectrum light formed by focusing and filtering a very high-intensity light source. Its essence is an incoherent ordinary light rather than a laser.

[0004] In order to penetrate deeper layers of the skin, the energy generated by IPL needs to be increased, so a high-power IPL is needed.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: When performing skin treatment, the circuit board controls the laser to emit laser light. The laser light passes through the optical waveguide, and the optical waveguide converges the laser light. Then the converged laser light passes through the treatment head to reach the skin. Under the same laser and IPL volume, the energy generated by the laser is greater than that generated by the IPL. Therefore, without increasing the volume of the outer shell, using the laser can generate higher energy and can perform deeper treatment on the skin; the fan blows the radiator, and the air flow takes away the heat transferred from the radiator, which can dissipate the heat of the treatment head and the laser; When using the skin rejuvenation device, the treatment head is brought close to the user's skin. When the four conductive columns come into contact with the skin, the conductive columns transmit signals to the annular circuit board, and the annular circuit board controls the laser to emit laser light. If not all in contact, the laser does not emit laser light; The upper cover and lower cover of the optical waveguide wrap the laser to prevent dust from contacting the laser and causing pollution to the laser; by using the shape setting of the optical waveguide, the parallel light beam generated by the laser is transformed into a circular light spot through the optical waveguide, making the laser more concentrated. The size of the treatment head is designed to be relatively compact, which is more convenient for treating facial skin; When dissipating the heat of the laser, the laser transfers heat to the upper base, and the upper base then transfers the heat to the first heat sink fin group and the second heat sink fin group through the first heat pipe and the second heat pipe. The fan blows away the heat, and thus the temperature of the laser can be reduced; The TEC transfers heat between the connection shell and the upper base. The fan blows the first heat sink fin group, and the first heat sink fin group realizes the temperature reduction of the upper base through the heat pipe effect of the first heat pipe. Heat transfer occurs between the upper base and the connection shell, reducing the temperature of the treatment head. When the treatment head and the lens contact the skin, it has a freezing point effect, making the treatment more comfortable; When treating the skin, to provide a better experience for the patient, under the action of the TEC, the treatment head has a freezing point experience when treating the patient's skin. When the temperature of the treatment head rises, the second temperature sensor receives the temperature rise signal and controls the fan to increase the rotation speed through the circuit board. Utilizing the heat pipe effect, the temperature of the TEC is reduced, and the temperature of the treatment head also decreases accordingly, enabling real-time cooling, protecting the patient's skin, and enhancing the patient's experience; when the temperature of the laser rises, the first temperature sensor receives the temperature rise signal and also controls the fan to increase the rotation speed through the circuit board. Utilizing the heat pipe effect, the temperature of the upper base is reduced, and the temperature of the laser also decreases accordingly, enabling real-time cooling and protecting the laser; Laser uses the photothermal effect to treat the skin. Without damaging the normal structure of the skin, it can improve the skin's metabolic capacity. Laser has a fixed wavelength. The wavelength of the laser is long and the penetration is deep. Especially when the laser wavelength is 1064nm, 1064nm is a near-infrared laser, which can be absorbed by melanin, water and hemoglobin at the same time. The 1064nm pulse width technology can penetrate deep into the fat layer, increase dermal collagen, effectively whiten and rejuvenate the skin, accelerate the metabolism of deep-layer melanin in the skin, improve skin pigmentation and dark spots, brighten and whiten the skin, stimulate the regeneration of dermal collagen, shrink pores, improve skin problems such as fine lines and nasolabial folds, make the skin fair, bright and younger, and make the skin brighten the skin tone, improve the skin texture, deeply resist allergies, lift and tighten.

[0036] The optical waveguide upper cover 41 and the optical waveguide lower cover 42 wrap the laser 5 to prevent dust from contacting the laser 5 and causing pollution to the laser 5; the shape of the optical waveguide 3 is used to convert the parallel light beam generated by the laser 5 into a circular light spot through the optical waveguide 3, making the laser more concentrated. The design size of the treatment head 2 is relatively compact, which is more convenient for treating facial skin.

[0037] The radiator 6 is made of aluminum alloy. The radiator 6 includes an upper base 61, a lower base 62, a first heat pipe 63, a second heat pipe 64, a first heat sink fin group 65 and a second heat sink fin group 66. Both the upper base 61 and the lower base 62 are installed in the housing 1. The first heat pipe 63 and the second heat pipe 64 are integrally formed on the same side surface of the lower base 62.

An installation groove 611 is provided on the side surface of the upper base 61 away from the lower base 62. The optical waveguide upper cover 41 is connected to the side surface of the upper base 61 away from the lower base 62.

One end of the optical waveguide 3 close to the laser 5 is attached to the bottom surface of the installation groove 611. The optical waveguide upper cover 41 and the upper base 61 clamp the optical waveguide 3.

[0038] When dissipating heat from the laser 5, the laser 5 transfers heat to the upper base 61, and then the upper base 61 transfers the heat to the first heat sink fin group 65 and the second heat sink fin group 66 through the first heat pipe 63 and the second heat pipe 64.

The first heat sink fin group 65 cools the upper base 61 through the heat pipe effect of the first heat pipe 63. Heat is transferred between the upper base 61 and the connection shell 22, reducing the temperature of the connection shell 22. Since the mounting ring 21 and the connection shell 22 are integrally designed, the temperature of the mounting ring 21 also decreases, resulting in an ice point effect when the mounting ring 21 and the lens 23 contact the skin, making the treatment more comfortable.

The first temperature sensor 612 and the second temperature sensor 222 transmit the collected temperature to the circuit board 8. The circuit board 8 processes and identifies the signal, and then transmits a signal to the fan 7 to control the rotation speed of the fan 7. When the temperature is too high, the rotation speed of the fan 7 increases. When the temperature is relatively low, the rotation speed of the fan 7 is small or even does not rotate, and it is in the standby mute state. When treating the skin, for a better experience of the patient, under the action of the TEC 27, the treatment head 2 has a freezing point experience when treating the patient's skin. When the temperature of the treatment head 2 rises, the second temperature sensor 222 receives the temperature rise signal, and controls the fan 7 to increase the rotation speed through the circuit board 8. Utilizing the heat pipe effect, the temperature of the TEC 27 is reduced, and the temperature of the treatment head 2 also decreases accordingly, enabling real-time cooling, protecting the patient's skin, and enhancing the patient experience. When the temperature of the laser 5 rises, the first temperature sensor 612 receives the temperature rise signal, and also controls the fan 7 to increase the rotation speed through the circuit board 8. Utilizing the heat pipe effect, the temperature of the upper base 61 is reduced, and the temperature of the laser 5 also decreases accordingly, enabling real-time cooling, protecting the laser 5.

The circuit board 8 is connected to the lower base 62 of the radiator 6. The optical waveguide 3 is installed in the optical waveguide cover 4. The laser 5 is installed in the optical waveguide cover 4, so that the radiator 6, the optical waveguide 3, the laser 5 and the circuit board 8 form an integral component, becoming the most core components, facilitating production, installation, debugging and maintenance.

[0047] A lamp board 411 is installed on the side of the upper optical waveguide cover 41 away from the lower optical waveguide cover 42. The lamp board 411 is close to the side of the upper optical waveguide cover 41 and is surface-mounted with RGB three-color LED high-brightness lamp beads. The irradiation direction is perpendicular to the light source output direction of the laser 5. The light of the RGB three-color LED high-brightness lamp beads passes through the upper optical waveguide cover 41, uses the optical waveguide 3 for optical path shaping and light guiding, and is output through the treatment window of the optical waveguide 3. The treatment area is exactly the same as the light source spot. Since the treatment laser of the laser 5 is 1064 nm, which is invisible light and difficult to identify the treatment area, under the irradiation of the RGB three-color LED high-brightness lamp beads, full-color output can be achieved to meet the customized requirements. By increasing the output of visible light from the treatment window as an indication, it is indicated that the spot shape coincides with the area being treated, and the user can directly observe the treatment area, thereby effectively avoiding the defects of repeated treatment in some areas and missed treatment in some areas. The visible light can be realized by surface-mounting LED lamp beads on the circuit board 8, with simple technology, low cost, and full-color indication light can be output through the RGB three-color lamp beads.

[0048] The specific parameter requirements of the laser 5 in the embodiment of the present application are as follows: The laser wavelength range of laser 5 is 500-2000nm, and the optimal wavelength is 1064nm; the peak power range of laser 5 is 1W-200W, and the optimal power is 30W; the laser pulse width range of laser 5 is 1ms-900ms, and the optimal pulse width is 400ms; the energy density of laser 5 is 10J / cm 2 ; Laser 5 can be a single wavelength or a combination of multiple wavelengths.

[0049] Laser uses the photothermal effect to treat the skin, improving the skin's metabolic capacity without destroying the skin's normal structure. Laser has a fixed wavelength, a long wavelength, and deep penetration, especially when the laser wavelength is 1064nm, 1064nm is a near-infrared laser, which can be absorbed by melanin, water, and hemoglobin at the same time. The 1064nm pulse width technology can penetrate deep into the fat layer, increase dermal collagen, and effectively whiten and rejuvenate the skin, accelerate the metabolism of deep melanin in the skin, improve pigmentation, brighten and whiten the skin, stimulate the regeneration of collagen in the dermis, shrink pores, improve fine lines, nasolabial folds and other skin problems, make the skin white, translucent and younger, make the skin brighter, improve skin texture, deeply anti-allergic, and lift and tighten.

[0050] The implementation principle of a home-use laser freckle removal and anti-aging beauty instrument in an embodiment of the present application is as follows: when performing skin treatment, the circuit board 8 controls the laser 5 to emit laser, the laser passes through the optical waveguide 3, the optical waveguide 3 collects the laser, and then the collected laser passes through the treatment head 2 to reach the skin. Under the same volume of the laser 5 and IPL, the energy generated by the laser is greater than the energy generated by the IPL. Therefore, without increasing the volume of the outer shell 1, the use of the laser 5 can generate higher energy and can perform deeper treatment on the skin; the fan 7 blows the radiator 6, and the airflow takes away the heat transferred from the radiator 6, which can dissipate heat for the treatment head 2 and the laser 5.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
