DETAILED DESCRIPTION

[0022] Intense pulsed light photon rejuvenation devices used at home or in hospitals are mainly used for photon treatment of the skin. However, the surface conditions of different parts of the human skin are different. For example, some parts have spots, some have heavy red bloodshot cheeks, some have larger pores in and around the nostrils, and some have longer hair at the corners of the lips.

[0023] Therefore, the intense pulsed light photon skin rejuvenation device needs to output pulsed light of different bands to cope with different skin conditions. In the prior art, it is usually necessary to manually switch the output head of the intense pulsed light photon skin rejuvenation device (that is, replace the filter), which makes the use of the intense pulsed light photon skin rejuvenation device very troublesome.

[0024] See also Figure 1-Figure 4 In order to solve the problem of difficult head switching of existing intense pulsed light photon skin rejuvenation devices, the present application provides a photon skin rejuvenation device, which includes a shell 100, a rotating bracket 310, a first motor 330, a control module (not shown), a sensing and recognition module, a pulse light output module 340 and a plurality of filters 320. The rotating bracket 310, the first motor 330, the control module, the pulse light output module 340 and the plurality of filters 320 are all arranged in the shell 100, and the sensing and recognition module is arranged on the outside of the shell 100.

[0025] Among them, the pulse light output module 340 can output strong pulse light with a wavelength of 500nm-1200nm. The basic principle of the filter 320 is: using its specific optical material and structure, only light in a specific wavelength range can pass through the filter 320, and light of other wavelengths is blocked or absorbed.

[0026] The plurality of filters 320 are respectively arranged on different sides of the rotating bracket 310, and the rotating bracket 310 is connected to the output end of the first motor 330. In addition, the control module is respectively electrically connected to the pulse light output module 340, the sensing recognition module and the first motor 330, and the sensing recognition module is used to sense and recognize different skin states, and can transmit the corresponding skin state information to the control module, so that the control module can control the first motor 330 to drive the rotating bracket 310 to drive the plurality of filters 320 to rotate at different angles, and the control module can control the pulse light output module 340 to emit strong pulse light of different wavelengths through different filters 320.

[0027] Specifically, photon therapy mainly includes photon therapy in four wavelength bands: 420nm, 540nm, 570nm and 650nm. Among them, photons with a wavelength of 570nm are often used to treat freckles, seborrheic keratosis (age spots), solar lentigo (commonly known as sun spots) and some melasma, etc.; photons with a wavelength of 540nm are used to treat telangiectasia (commonly known as red blood streaks), rosacea and some hemangiomas, etc.; photons with a wavelength of 420nm are often used to treat moderate to severe inflammatory acne; photons with a wavelength of 650nm are often used to treat hirsutism and those who need hair removal.

[0028] Therefore, in this embodiment, the rotating bracket 310 is tetrahedral, and the four-band filters 320 are respectively arranged on the four sides of the rotating bracket 310. A pulse light output module 340 (not shown) and a reflector (not shown) are provided inside the rotating bracket 310. The reflector can reflect the strong pulse light output by the pulse light output module 340 to the corresponding filter 320.

[0029] Furthermore, both ends of the rotating bracket 310 are tapered, which is convenient for installing the rotating bracket 310 .

[0030] Specifically, in one embodiment, if Figure 2 As shown, the sensing and identifying module includes an image sensor 410 , which can automatically sample and identify the skin surface so that the control module can control the first motor 330 to rotate.

[0031] Image sensor 410 has a high resolution and can quickly and accurately identify features on the skin surface.

[0032] In another embodiment, if Figure 2 As shown, the sensing identification module includes an impedance sensor 420, which can convert changes in non-electrical physical quantities on the skin surface into changes in resistance values, and output the changed electrical signals to the control module so that the control module can control the rotation of the first motor 330.

[0033] Specifically, the impedance sensor 420 includes a capacitive impedance sensor, an inductive impedance sensor, and a piezoelectric impedance sensor. The capacitive impedance sensor is a sensor that uses a change in capacitance value for measurement. When the physical quantity to be measured changes, factors such as the capacitor spacing and the plate area can be changed to change the capacitance value, thereby obtaining the desired measurement value. For example, a capacitive impedance sensor can be used to measure physical quantities such as temperature, humidity, and pressure on the skin surface.

[0034] An inductive impedance sensor is a sensor that uses changes in inductance to perform measurements. When the measured physical quantity changes, factors such as the structure of the inductor and the shape of the coil can be changed to change the inductance value and obtain the desired measurement value. For example, inductive impedance sensors can be used to measure physical quantities such as current, displacement, and velocity.

[0035] A piezoelectric impedance sensor is a sensor that uses the piezoelectric effect for measurement. When the measured physical quantity changes, factors such as the shape or size of the piezoelectric crystal can be changed to change the charge distribution and obtain the desired measurement value. For example, a piezoelectric impedance sensor can be used to measure physical quantities such as pressure, weight, and acceleration.

[0036] It should be noted that, in other embodiments, the sensing and identification module may also be a combination of the image sensor 410 and the impedance sensor 420 , both of which will greatly improve the sensing accuracy of the sensing and identification module.

[0037] When the photon skin rejuvenation device is in use, the user can aim the output end of the photon skin rejuvenation device at the skin surface, and the control module controls the pulse light output module 340 to preheat the skin surface at 3 watts for 5 seconds, so that the temperature of the skin surface is greater than the minimum critical value. Of course, in other cases, the pulse light output module 340 can also preheat the skin surface at other powers for other times, for example, the pulse light output module 340 preheats the skin surface at 2 watts for 7.5 seconds.

[0038] In one embodiment, if Figure 2 As shown, the photon rejuvenation device also includes a temperature sensor 430, which is electrically connected to the control module. When the temperature sensor 430 detects that the temperature value of the skin surface is lower than the standard value, the control module can control the pulse light output module 340 to increase the duty cycle of the output intense pulse light to increase the power of the pulse light output module 340 to heat the skin surface.

[0039] When the temperature sensor 430 detects that the temperature value of the skin surface is greater than the standard value, the control module can control the pulse light output module 340 to reduce the duty cycle of the output intense pulse light to reduce the power of the pulse light output module 340 to heat the skin surface.

[0040] Specifically, the standard value may be any value within the range of 20°C-50°C.

[0041] This setting allows the skin to be treated with intense pulsed light at the most suitable temperature, greatly improving the skin treatment effect.

[0042] Furthermore, in one embodiment, the photon rejuvenation device also includes a cooling module (not shown), and the control module is electrically connected to the cooling module. When the temperature sensor 430 detects that the temperature value of the skin surface is greater than or equal to the maximum warning value, the control module can control the cooling module to cool the skin surface, wherein the maximum warning value is greater than the standard value.

[0043] Such an arrangement can quickly avoid skin burns, thereby effectively protecting the healer.

[0044] More specifically, the refrigeration module may be a fan or a sprayer, etc., which are not listed here one by one.

[0045] In one embodiment, if Figure 2As shown, the photon skin rejuvenation device also includes a water-oil bomb sensor 440, which is used to test the water content of the skin. In addition, the water-oil bomb sensor 440 is electrically connected to the control module. When the water content of a certain part of the skin is less than the reference value, it also means that the elasticity of the skin is poor. The water-oil bomb sensor 440 can transmit the water content information of the skin to the control module, and display the water content of the skin through the control module to remind the user to extend the stay time of the photon skin rejuvenation device on the skin at that place.

[0046] It should be noted that the working principle of the water-oil elastic sensor 440 is to utilize the electrophysiological characteristics of the skin to change synchronously with the change of the epidermal hydration condition, and indirectly reflect the skin water content by measuring the electrophysiological parameters.

[0047] In addition, the oil content of the skin can be calculated through the moisture test results. The approximate conversion relationship is: 10%-35% water content corresponds to 20%-63% oil content, 35%-60% water content corresponds to 33%-17% oil content, and water content greater than 60% means the oil content is around 20%.

[0048] The photon skin rejuvenation device provided in this application can use the image sensor 410, the impedance sensor 420, the temperature sensor 430 and the water-oil elastic sensor 440 to deeply treat the problems on the skin surface and control the treatment time to achieve precise skin care. In addition, the temperature sensor 430 can also be linked with the refrigeration module to achieve rapid feedback of the skin surface temperature and rapid cooling to prevent skin burns.

[0049] When encountering skin in different states, the sensing recognition module can automatically recognize the surface state of the skin, and directly control the rotation of the first motor 330 through the control module, so that the rotating bracket 310 changes the position of the filter 320, and then outputs the corresponding wavelength of intense pulsed light. From the above, it can be seen that the photon skin rejuvenation device provided by the present application can not only automatically switch the filter 320, but also automatically recognize the skin state and automatically adjust the output wavelength according to the actual skin state. Therefore, the photon skin rejuvenation device provided by the present application is not only easy to use but also highly intelligent, which greatly improves the user experience.

[0050] In one embodiment, if Figure 2 and Figure 4 As shown, the photon skin rejuvenation device also includes a contact piece 510 and a radio frequency electrode 520. The contact piece 510 is arranged at the head of the photon skin rejuvenation device so that the intense pulsed light can be emitted outward through the contact piece 510. The radio frequency electrode 520 is electrically connected to the control module, and the radio frequency electrode 520 is arranged on the peripheral side of the contact piece 510.

[0051] Specifically, the radio frequency electrode 520 is mainly used to heat the collagen under the skin, so that the face is firm and wrinkles can be removed. The radio frequency electrode 520 can be used in combination with the pulse light output module 340. First, the strong pulse light can be used to quickly reduce the skin impedance. Then, the radio frequency can quickly enter the dermis to heat the collagen and make it proliferate, so as to achieve the effect of firming the skin.

[0052] Since the contact sheet 510 and the radio frequency electrode 520 are likely to directly contact the skin, they are easily contaminated with bacteria or viruses.

[0053] Therefore, in one embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the photon skin rejuvenation device also includes a base 200, and the head of the photon skin rejuvenation device can be inserted into the base 200, and can be charged through the base 200. In this way, on the one hand, the photon skin rejuvenation device itself can be installed and positioned, and on the other hand, before use, the user can press the sterilization mode to use the sterilization function of the intense pulsed light itself. The intense pulsed light can sterilize the head of the photon skin rejuvenation device (including the contact piece 510 and the radio frequency electrode 520), thereby ensuring that the head of the photon skin rejuvenation device is clean and sterile. In addition, an intense pulsed light with a wavelength of 420nm is usually used for sterilization.

[0054] In one embodiment, if Figure 2-Figure 4 As shown, the photon rejuvenation device also includes a battery 600, a fan 700 and a partition assembly 110. The partition assembly 110 is arranged in the shell 100 and is surrounded by the shell 100 to form an air duct 120. One end of the air duct 120 is connected to the fan 700, and the other end is connected to the battery 600. In addition, the pulse light output module 340 is arranged in the air duct 120. The shell 100 is provided with an air inlet 130 connected to the air duct 120. The fan 700 can drive external air to blow toward the battery 600 through the air inlet 130 and the air duct 120.

[0055] It should be noted that the photorejuvenation device can also be plugged in and used without the battery 600.

[0056] Since the pulse light output module 340 is disposed in the air duct 120, when the temperature is low in winter, the pulse light output module 340 can heat the air in the air duct 120 and blow the hot air toward the battery 600 to improve the problem of poor charging of the battery 600 in a low temperature state. In addition, heating the entire housing 100 of the photorejuvenation device through the air duct 120 can also improve the problem of being cold when holding the housing 100.

[0057] Specifically, in one embodiment, if Figure 2-Figure 4As shown, the battery 600 and the pulse light output module 340 are respectively arranged at the two ends of the shell 100, the fan 700 is arranged between the battery 600 and the pulse light output module 340, that is, the fan 700 is arranged in the middle part of the shell 100, and the air duct 120 is arranged on the inner peripheral side of the shell 100, that is, the air duct 120 is clamped between the outer peripheral side of the fan 700 and the inner wall of the shell 100.

[0058] Such a layout can increase the travel of the air duct 120 , which is beneficial for the hot air in the air duct 120 to heat the entire housing 100 .

[0059] But it is not limited thereto. In other embodiments, the battery 600 may be disposed between the fan 700 and the pulse light output module 340 .

[0060] Furthermore, the inner surface of the contact piece 510 is also connected to the air duct 120, so that hot air can heat the RF electrode 520 and the contact piece 510, thereby preventing the head of the photorejuvenation device from feeling cold.

[0061] Further, in one embodiment, if Figure 3 As shown, the photon skin rejuvenation device further includes a second motor 810, a screw 820 and a valve 830. The second motor 810 is electrically connected to the control module. One end of the screw 820 is connected to the output end of the second motor 810, and the other end is movably threaded with the valve 830. The valve 830 is movably inserted into the air duct 120, and the second motor 810 can control the screw 820 to rotate to push the valve 830 to open or close the air duct 120.

[0062] In this way, when the battery 600 or the housing 100 reaches an optimal temperature (usually 25° C.), the valve 830 can close the air duct 120 to prevent the battery 600 or the housing 100 from being overheated.

[0063] Furthermore, the housing 100 is provided with an air outlet (not shown) connected to the air duct 120. When the valve 830 closes the air duct 120, the wind in the air duct 120 can be discharged into the atmosphere through the air outlet.
