Description

Technical Field

[0001] The present invention relates to the technical field of laser treatment equipment, in particular to a home-use laser freckle removal 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 jawline, double chin, and downward shift of the apple muscles.

[0003] The most common home rejuvenation device on the market is the IPL photon 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. However, the corresponding skin rejuvenation device will be designed to be larger and more bulky, which makes the treatment of facial skin extremely inconvenient and not suitable for home use.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During skin treatment, the circuit board controls the laser to emit laser light, which then passes through the optical waveguide and is collected by the optical waveguide. The collected laser light then passes through the treatment head and reaches 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 size of the housing, the laser can generate higher energy and provide deeper skin treatment. The fan blows the heat sink, and the airflow carries away the heat transferred from the heat sink, which can dissipate heat from the treatment head and laser.

[0029] 2. When using the skin rejuvenation device, place the treatment head close to the user's skin. When the four conductive pillars touch the skin, the conductive pillars transmit signals to the ring circuit board, which controls the laser to emit laser light. If not all of them touch the skin, the laser will not emit laser light.

[0030] 3. The upper and lower optical waveguide covers enclose the laser to prevent dust from contacting the laser and causing contamination. The shape of the optical waveguide transforms the parallel beam generated by the laser into a circular spot through the optical waveguide, making the laser more concentrated. The treatment head is designed to be relatively compact, making it easier to treat facial skin.

[0031] 4. When cooling the laser, the laser transfers heat to the upper base, which then transfers the heat to the first and second heat pipes through the first and second heat pipes. The fan blows away the heat, thereby cooling the laser.

[0032] 5. TEC transfers heat between the connecting shell and the upper base. The fan blows the first heat dissipation fin group, which cools the upper base through the heat pipe effect of the first heat pipe. Heat is transferred between the upper base and the connecting shell, reducing the temperature of the treatment head. When the treatment head and lens come into contact with the skin, they have a freezing point effect, making the treatment more comfortable.

[0033] 6. During skin treatment, to provide patients with a better experience, the TEC (Transistor-Electrolyte-Control) (TEC) allows the treatment head to provide a freezing point experience when treating the patient's skin. When the temperature of the treatment head rises, the second temperature sensor receives a temperature increase signal and controls the fan to increase its speed through the circuit board. This utilizes the heat pipe effect to lower the TEC temperature, thereby lowering the temperature of the treatment head. This provides real-time cooling, protects the patient's skin, and enhances the patient experience. When the laser temperature rises, the first temperature sensor receives a temperature increase signal and controls the fan to increase its speed through the circuit board. This utilizes the heat pipe effect to lower the temperature of the upper base, thereby lowering the temperature of the laser. This provides real-time cooling, protecting the laser.

[0034] 7. Laser uses the photothermal effect to treat the skin, improving the skin's metabolic capacity without destroying the normal structure of the skin; laser has a fixed wavelength, the laser wavelength is long, and the penetration is deep, especially when the laser wavelength is 1064nm, 1064nm is a near-infrared laser, it 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, lift and tighten.

The circuit board 8 is electrically connected to the fan 7.

[0046] During skin treatment, the circuit board 8 controls the laser 5 to emit laser light, which passes through the optical waveguide 3, which collects the laser light. The collected laser light then 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 light is greater than the energy generated by the IPL. Therefore, without increasing the volume of the housing 1, the use of the laser 5 can generate higher energy and can provide deeper treatment to 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 from the treatment head 2 and the laser 5.

A lens 23 is embedded on the side of the mounting ring 21 close to the connecting shell 22. The laser passes through the lens. 23; Four mounting holes 211 are provided on the mounting ring 21, and the four mounting holes 211 are arranged around the mounting ring 21. An insulating sleeve 24 is embedded in the inner wall of the mounting hole 211, and a conductive column 25 is passed through the insulating sleeve 24. The conductive column 25 is a copper guide column. An annular circuit board 26 is provided on the side of the mounting ring 21 close to the connecting shell 22, and an insulating layer is coated on the side of the mounting ring 21 close to the annular circuit board 26. The end of the conductive column 25 is connected to the annular circuit board 26, and the end of the conductive column 25 away from the annular circuit board 26 contacts the user's skin.

[0049] When using the skin rejuvenation device, the treatment head 2 is placed close to the user's skin. When the four conductive columns 25 touch the skin, the conductive columns 25 transmit signals to the ring circuit board 26, and the ring circuit board 26 controls the laser 5 to emit laser light. If not all of them touch the skin, the laser 5 will not emit laser light.

[0050] The optical waveguide cover 4 includes an optical waveguide upper cover 41 and an optical waveguide lower cover 42. The optical waveguide upper cover 41 is connected to the optical waveguide lower cover 42. The laser 5 is installed between the optical waveguide upper cover 41 and the optical waveguide lower cover 42. The optical waveguide upper cover 41 and the optical waveguide lower cover 42 seal the laser 5. The emitting end of the laser 5 is rectangular. Multiple parallel light beams are emitted from the laser 5. All parallel light beams are located in the same plane. One section of the optical waveguide 3 is installed on the inner wall of the connecting shell 22, and the other section of the optical waveguide 3 is installed on the inner wall of the optical waveguide upper cover 41. The optical waveguide 3 is located between the laser 5 and the lens 23. One end of the optical waveguide 3 is rectangular, and the other end of the optical waveguide 3 is circular. The rectangular end face of the optical waveguide 3 is close to the rectangular end face of the laser 5, and the circular end face of the optical waveguide 3 is aligned with the lens 23.

[0051] 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 setting 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.

[0052] 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 dissipation fin group 65 and a second heat dissipation fin group 66. The upper base 61 and the lower base 62 are both installed in the housing 1. The first heat pipe 63 and the second heat pipe 64 are both integrally formed on the same side of the lower base 62.

Connected to the same side of the upper base 61, the fan 7 is inserted between the first heat dissipation fin group 65 and the second heat dissipation fin group 66; the upper base 61 is arranged in the mounting groove 611 on the side away from the lower base 62, the optical waveguide upper cover 41 is connected to the side of the upper base 61 away from the lower base 62, the optical waveguide lower cover 42 is attached to the inner wall of the mounting groove 611, the emitting end of the laser 5 is located on the top surface of the optical waveguide lower cover 42, and the other end of the laser 5 is attached to the side of the upper base 61 away from the lower base 62; the end of the optical waveguide 3 close to the laser 5 is attached to the bottom surface of the mounting groove 611, and the optical waveguide upper cover 41 and the upper base 61 clamp the optical waveguide 3.

[0053] When the laser 5 is being cooled, the laser 5 transfers heat to the upper base 61 , and the upper base 61 then transfers the heat to the first heat dissipation fin group 65 and the second heat dissipation fin group 66 through the first heat pipe 63 and the second heat pipe 64 .

[0055] TEC27 transfers heat between the connecting shell 22 and the upper base 61, and the fan 7 blows the first heat dissipation fin group 65. The first heat dissipation 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 connecting shell 22, so that the temperature of the connecting shell 22 is reduced. Because the mounting ring 21 and the connecting shell 22 are designed as an integral whole, the temperature of the mounting ring 21 will also be reduced, so that when the mounting ring 21 and the lens 23 contact the skin, there is a freezing point effect, and the treatment is more comfortable.

[0057] The fan 7 is started to draw air in from the air inlet 122 and blow it out from the air outlet 111, taking away the heat on the first heat dissipation fin group 65 and the second heat dissipation fin group 66. Since the fins of the first heat dissipation fin group 65 and the fin surfaces of the second heat dissipation fin group 66 are provided with rough protrusions, the air flow is easily retained between the fins, so that the flowing air flow can take away more heat.

When the temperature is too high, the speed of the fan 7 increases. When the temperature is low, the speed of the fan 7 is small, or even does not rotate, and is in a standby silent state; when treating the skin, in order to give the patient a better experience Now, under the action of TEC27, 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 a temperature increase signal, and controls the fan 7 to increase the speed through the circuit board 8.

[0062] A light board 411 is mounted on the side of the optical waveguide cover 41, away from the optical waveguide cover 42. This board is close to the side of the optical waveguide cover 41, and is equipped with an RGB tri-color LED high-brightness lamp bead. The illumination direction is perpendicular to the output direction of the laser light source 5.

The light is output through the treatment window of the optical waveguide 3, and the treatment area is completely consistent with the light source spot. Since the treatment laser of the laser 5 is 1064nm, which is invisible light and difficult to identify the treatment area, the RGB tri-color LED high-brightness lamp bead can achieve full-color output, meeting customized needs. By adding visible light output from the treatment window as an indicator, the indicator spot shape coincides with the area being treated, and the user can directly observe the treatment area, effectively avoiding the defects of repeated treatment in some areas and missing treatment in others. The visible light can be achieved using the SMD LED lamp bead on the circuit board 8, which is simple to process and inexpensive. Moreover, the RGB tri-color lamp bead can output full-color indicator light.

[0063] The specific parameter requirements of the laser 5 in the embodiment of the present application are as follows:

[0064] The laser wavelength range of laser 5 is 500-2000nm, with an optimal wavelength of 1064nm; the peak power range of laser 5 is 1W-200W, with an optimal power of 30W; the laser pulse width range of laser 5 is 1ms-900ms, with an optimal pulse width of 400ms; the energy density of laser 5 is 10J / cm 2 ; The laser 5 can be a single wavelength or a combination of multiple wavelengths.

[0065] 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 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, lift and tighten.

[0066] The implementation principle of a home laser freckle removal beauty device 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 laser 5 and IPL volume, the energy generated by the laser is greater than the energy generated by the IPL. Therefore, without increasing the volume of the housing 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.

[0067] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
