Description

Technical Field

[0001] This utility model relates to the field of beauty and skincare instrument technology, and more specifically to a strong pulsed light instrument with interchangeable output effects. Background Technology

[0002] With the increasing sophistication of the beauty and skincare industry, different groups of people have developed personalized and precise requirements for the energy, wavelength, and light emission area of ​​Intense Pulsed Light (IPL) beauty devices due to their skin type, the areas being treated, and their specific needs. However, IPL releases a large amount of heat energy instantaneously during operation. If heat dissipation is not timely, it can easily cause a sudden rise in skin temperature, leading to burning, stinging, or even skin damage.

[0003] Currently, mainstream instruments typically employ one of two solutions to address this issue: First, they integrate a cooling module into the main unit to generate low temperatures that contact the skin and alleviate heat damage. However, these instruments require external accessories to adjust the light output area, and these accessories can disrupt the contact between the cooling component and the skin, causing the cooling function to fail and putting the user back at risk of heat damage. Second, they integrate filters into pluggable accessories to achieve wavelength switching. However, the cooling component is fixed and cannot be replaced. Since the cooling component needs to directly contact the skin, it is prone to leaving contaminants when shared by multiple people, posing a risk of cross-infection and limiting the instrument's application in homes, small groups, and other similar settings.

[0004] Therefore, existing high-intensity pulsed light instruments cannot simultaneously achieve adjustable light output parameters, reliable cooling effect, and hygienic use. There is an urgent need for a new solution to achieve synergistic optimization of these three aspects and address the industry's pain points. Utility Model Content

[0015] In one embodiment, the host computer is provided with a main control board, which can detect the voltage of the connecting board to drive the flashing mechanism to output light energy according to a preset voltage and flashing time.

[0016] In one embodiment, the flash mechanism includes: a bracket, a lamp tube, a filter, and a reflector; the reflector is disposed inside the output head, and the open end of the reflector is positioned directly opposite the light outlet; the filter is disposed at the open end of the reflector, and the lamp tube is disposed between the filter and the reflector; one end of the bracket is connected to the lamp tube, and the other end is electrically connected to the connecting plate.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0030] See Figures 1 to 5 As shown, this embodiment discloses a high-intensity pulsed light instrument with interchangeable output effects, which includes: a main unit 1 and an output head 2 detachably connected to the main unit 1; one end face of the output head 2 is provided with a light outlet 21, and the output head 2 is provided with a connecting plate 24 and a flash mechanism 22 and a cooling mechanism 23 electrically connected to the connecting plate 24; the flash mechanism 22 is arranged facing the light outlet 21 and is used to output high-intensity pulsed light; the cooling mechanism 23 is used to reduce the temperature of the end face of the light outlet 21 of the output head 2; the connecting plate 24 extends from the inside of the output head 2 to the side away from the light outlet 21, the output end of the main unit 1 is provided with an interface 11, and the connecting plate 24 is plugged into and unplugged into the interface 11 to be electrically connected or disconnected from the main unit 1.

[0031] In practice, users can select the appropriate output head 2 according to the target area of ​​the beauty treatment and the characteristics of the skin and the target object. For example, a strong pulse light output head 2 with a small light-emitting area is used to remove hair from the fingers, while a strong pulse light output head 2 with a large light-emitting area is used to remove hair from the limbs. Then, the appropriate output head 2 is installed on the output end of the host 1, and its connection plate 24 is electrically connected to the host 1, so that the host 1 controls the output head 2 to output the preset flashing effect and cooling effect. Users can also replace the output head 2 to select the output head 2 they want to use if the user changes.

[0032] This embodiment of the high-intensity pulsed light (HIPL) instrument with interchangeable output effects integrates the flash mechanism 22 and cooling mechanism 23 into a detachable output head 2. This allows for adjustment of the output effect by changing the size of the output port 21, the flash effect, and the cooling effect of the output head 2. This caters to users' precise beauty and skincare needs, such as removing unwanted hair, rejuvenating skin, treating acne and wrinkles, treating acne vulgaris, treating capillaries and reticular veins, treating port-wine stains, and treating scars. Furthermore, during use, users can select output heads 2 with different output port 21 areas without the need for assembly. The adjustable light-emitting area of ​​the accessory interferes with the cooling mechanism 23, maintaining the reliability and effectiveness of the cooling effect and avoiding thermal damage to the user. Furthermore, the replaceable design of the output head 2 is suitable for use scenarios where one person uses one output head 2, ensuring hygiene for multiple users. This allows family members or small groups to share one main unit 1 and use their own dedicated output head 2, avoiding cross-infection. In addition, it is convenient for users to replace the output head 2 when it is used for a long time or when it is damaged, which can extend the service life of the intense pulsed light instrument and improve its market competitiveness.

[0033] In a further embodiment, the end of the output head 2 furthest from the light outlet 21 is provided with several latches 25, and the output end of the host 1 is provided with a slot 12 corresponding to the latches 25. The latches 25 engage or disengage with the slots 12. Through the mechanical engagement structure between the latches 25 of the output head 2 and the slots 12 of the host 1, the output head 2 and the host 1 are quickly and physically fixed. At the same time, in conjunction with the insertion and removal of the connecting plate 24 and the interface 11 of the host 1, the mechanical and electrical connections between the output head 2 and the host 1 are double-fixed, ensuring that the output head 2 does not loosen and the electrical connection is stable during use.

[0034] In a further embodiment, the host 1 is provided with a main control board 13, which can detect the voltage of the connecting plate 24 to drive the flashing mechanism 22 to output light energy according to a preset voltage and flashing time. More specifically, the connecting plate 24 is provided with detection resistors of different resistance values, and the resistance values ​​of the detection resistors on different output heads 2 are different. After the host 1 connects to the output head 2, the main control board 13 detects the voltage of the connecting plate 24. Since different detection resistors correspond to different voltages, the host 1 can obtain the type and parameters of the output head 2 based on the detected voltage value. After obtaining the voltage value of the output head 2, the host 1 controls the voltage of the energy storage capacitor on the connecting plate 24 or makes it output a corresponding pulse width by changing the PWM parameters, thereby adjusting the voltage or flashing time of the lamp tube 222, and thus making the lamp output corresponding light energy. On the other hand, the main control board 13 can control the single-chip step-down converter on the connecting plate 24, adjust the power supply voltage of the cooling chip 232, change its cooling power, and make the cooling effect match the light energy. The setup of the main control board 13 and the connection board 24 enables automatic identification of the output head type 2 and can synchronously adapt to flash and cooling parameters without manual adjustment, making operation convenient.

[0035] In a further embodiment, interface 11 is electrically connected to main control board 13; the connecting board 24 is provided with gold fingers, which are used to plug into interface 11 and realize the electrical connection between connecting board 24 and main control board 13. It can be understood that gold fingers are conductive contact components in electronic hardware, composed of gold-colored contacts arranged in a finger-like shape. The surface is plated with gold or tin to achieve signal transmission, and has the functions of anti-oxidation and reducing contact resistance, enabling them to be used for plugging into interface 11. Compared with traditional wire connections, the plugging structure of gold fingers and interface 11 has lower contact resistance and higher power transmission efficiency, avoiding unstable power supply to components due to poor contact. At the same time, the plugging method is convenient to operate; when the user replaces output head 2, electrical connection can be completed simply by plugging and unplugging the gold fingers and interface 11, without the need for additional wiring, making output head 2 detachable and plug-and-play.

[0036] Traditional intense pulsed light (IPL) devices use a single filter 223 integrated into the main unit 1, which cannot be replaced. This limits the application to a wide-band coverage, increasing the risk of skin damage from ineffective wavelengths of IPL. Therefore, the IPL device of this embodiment features an independent flash mechanism 22 on each output head 2. This allows users to replace the filter 223 by changing the output head 2, achieving the desired cosmetic effect while reducing the damage to the skin from ineffective wavelengths of IPL and excessive heat generated outside the desired wavelength range. More specifically, the flash mechanism 22 of this embodiment includes: a bracket 221, a lamp tube 222, a filter 223, and a reflector 224; the reflector 224 is disposed inside the output head 2, and the open end of the reflector 224 is positioned directly opposite the light outlet 21; the filter 223 is disposed at the open end of the reflector 224, and the lamp tube 222 is disposed between the filter 223 and the reflector 224; one end of the bracket 221 is connected to the lamp tube 222, and the other end is electrically connected to the connecting plate 24. The bracket 221 fixes the lamp tube 222 and supplies power through the connecting plate 24. When the host 1 is triggered, the xenon gas in the lamp tube 222 ionizes and releases strong pulse light. The reflector 224 reflects the light 360° to the light outlet 21 to increase the light energy. After the filter 223 filters out invalid wavelengths, the light is output through the light outlet 21.

[0037] In a further embodiment, the cooling mechanism 23 includes: a heat sink 231, a cooling element 232, and a conductive element 233; the heat sink 231 is arranged in parallel with the flashing mechanism 22, the cooling element 232 is disposed at one end of the heat sink 231 near the light outlet 21, and the cooling element 232 is electrically connected to the connecting plate 24; the conductive element 233 is disposed on the end face of the output head 2 where the light outlet 21 is located, and is connected to the cooling element 232. More specifically, the cooling chip 232 operates on the principle of semiconductor thermoelectric cooling. It consists of multiple alternating P-type and N-type semiconductors. It receives power from the host 1 through the connecting board 24, which is electrically connected to the main control board 13. The main control board 13 is equipped with a single-chip step-down converter that can provide the appropriate operating voltage for the cooling chip 232. After being powered on, the electron flow inside the cooling chip 232 gains energy. Starting from the negative electrode, it absorbs heat when passing through the P-type semiconductor and releases heat when reaching the N-type semiconductor. Each time it passes through a PN semiconductor module, the heat is transferred from one side to the other, forming a cold end and a hot end. Preferably, the cold end and the hot end of the cooling chip 232 are each composed of two insulating ceramic sheets. The cold end of the cooling chip 232 is tightly connected to the conductive element 233 to transfer the cooling energy to the conductive element 233 to achieve cooling. The hot end is connected to the heat sink 231 to conduct heat away. The conductive element 233 is located on the end face of the light outlet 21, which can contact the user's skin and bring a cool experience to the user; after the host 1 starts the fan, it enters the air-cooling mode, and the airflow can carry away the heat of the heat sink 231, thereby cooling the conductive element 233 and reducing the temperature of the end face of the light outlet 21, achieving a cooling effect; in addition, the heat sink 231 and the flash mechanism 22 are arranged side by side to avoid mutual interference of their heat, ensure the heat dissipation efficiency of the hot end of the cooling chip 232, and thus maintain the stability of the cooling effect.

[0038] Preferably, the radiator 231 is made of a metal material with good thermal conductivity; the radiator 231 is provided with a plurality of heat dissipation fins 2311, and there are gaps between adjacent heat dissipation fins 2311. The gaps between adjacent heat dissipation fins 2311 increase the surface area of ​​the radiator 231, thereby increasing its heat dissipation area. When the air output by the host 1 acts on the radiator 231, the air can carry away the heat on the radiator 231 in time, so as to ensure the cooling effect of the cooling pad.

[0039] Understandably, during the production stage, the light-emitting area, cooling effect, and flashing effect of each output head 2, namely the area of ​​the light-emitting port 21, the type of the conductive component 233, and the energy of the flashing mechanism 22, can all be set according to actual needs, user preferences, and market demand.

[0040] In a further embodiment, the conductive element 233 is a cooling pad or sapphire; the conductive element 233 is arranged alongside or covers the light outlet 21. More specifically, the cooling pad is made of a metal material with good thermal conductivity; the sapphire is made of optical-grade sapphire crystal α-Al₂O₃ material. See also Figure 4 The output head 2 shown has a conductive element 233 that functions as a cooling pad. When the conductive element 233 functions as a cooling pad, it can quickly receive the cold energy transferred from the cold end of the cooling element 232 and distribute it evenly near the light outlet 21. It is also arranged parallel to the light outlet 21, allowing direct contact with the skin for cooling. (See also...) Figure 5 The output head 2 shown has a sapphire conductive element 233. Sapphire has both high thermal conductivity and light transmittance. While receiving cooling energy to cool the skin, it does not affect the penetration of the intense pulsed light to the target area of ​​the skin. Therefore, the sapphire can cover the light outlet 21, and its area is larger than the area of ​​the light outlet 21, achieving a large-area cooling effect. In specific implementation, users can choose output heads 2 equipped with different conductive elements 233 according to different usage needs. More specifically, the cooling pad has a lower cost and faster cooling speed, and is suitable for areas with low light transmittance requirements or small target areas. Sapphire has good light transmittance and high chemical stability, and is suitable for scenarios that require intense pulsed light penetration or large target areas. Both are directly compatible with the cooling pad 232. Changing the output head 2 can switch the type of conductive element 233 without additional adjustment of the cooling mechanism 23.

[0041] In a further embodiment, the end face of the output head 2 away from the light emission port 21 is provided with an air inlet 26a, a first air outlet 26b, and a second air outlet 26c. The output end of the host 1 is provided with an air outlet 15 and an air inlet 16 corresponding to the air inlet 26a and the first air outlet 26b. The air inlet 26a and the first air outlet 26b are linearly distributed along the length direction of the flash mechanism 22, and the second air outlet 26c is positioned directly opposite the heat sink 231. The air inlet 26a is used to guide airflow into the output head 1. Part of the airflow flows through the flash mechanism 22 and leaves the output head 2 through the first air outlet 26b, and part of the airflow flows through the heat sink 231 and leaves the output head 2 through the second air outlet 26c. More specifically, see Figure 1As shown, when the output head 2 is connected to the main unit 1, the second air outlet 26c is exposed outside the main unit 1. It is understood that the main unit 1 has a fan inside. When the main unit 1 is working, the internal fan starts, and external cold air enters through the air inlet 16 of the main unit 1, and then flows into the output head 2 through the air inlet 26a. The airflow entering the output head 2 is divided into two paths: one path passes through the flash mechanism 22 and flows to the first air outlet 26b, then flows back to the main unit 1 or is discharged through the air outlet 15 of the main unit 1, carrying away the heat generated by the lamp tube 222 in the flash mechanism 22; the other path passes through the heat sink 231 and flows to the second air outlet 26c, directly discharging outside the output head 2, carrying away the heat transferred from the hot end of the cooling element 232 to the heat sink 231, thus achieving heat dissipation between the flash mechanism 22 and the heat sink 231. The airflow diversion design makes the heat dissipation paths of the flash mechanism 22 and the heat sink 231 independent, avoiding the superposition of heat from the lamp tube 222 and the heat sink 231, and greatly improving the heat dissipation efficiency. The first air outlet 26b corresponds to the air outlet 15 of the host 1, and can enhance the airflow power with the help of the host 1 fan. The second air outlet 26c directly exhausts hot air, reducing the retention of hot air in the output head 2. In addition, the air inlet 26a and the first air outlet 26b are linearly distributed along the length of the flash mechanism 22, and the second air outlet 26c is set directly opposite the heat sink 231, so that the airflow is evenly covered in the output head 2, ensuring that there are no dead corners in heat dissipation.

[0042] In a further embodiment, the output head 2 is further provided with a sensing plate 27, which is electrically connected to the connecting plate 24 and located at the end of the flash mechanism 22 near the light outlet 21. More specifically, the sensing plate 27 has a through hole in its center, so that the sensing plate 27 is frame-shaped and arranged on the outer periphery of the filter 223 of the flash mechanism 22, thereby allowing the strong pulse light to be output to the user's skin surface sequentially through the filter 223, the through hole, and the light outlet 21. The sensing plate 27 is electrically connected to the main control board 13 of the host 1 through the connecting plate 24 and is located near the light outlet 21. When the light outlet 21 of the output head 2 is in contact with the skin, the sensing plate 27 contacts the skin and detects the skin contact signal, and transmits the signal to the host 1 through the connecting plate 24. Only after the host 1 receives a valid contact signal will it allow the flash mechanism 22 to trigger the flash. If no skin contact signal is detected or the contact is not tight, the host 1 will prevent the flash mechanism 22 from working to avoid the strong pulse light from being accidentally triggered and causing harm to the human body. Therefore, the sensor 27 is designed to fit snugly against the skin during use, avoid interference with the flash mechanism 22, and effectively mitigate the risk of erroneous output of strong pulse light in non-contact mode, thus improving product safety.

[0043] In a further embodiment, the output head 2 is also provided with a light guide post 28, which extends from the end face where the light outlet 21 is located to the other end; the host 1 is provided with a skin color recognition sensor 14, and when the output head 2 is connected to the host 1, the light guide post 28 is electrically connected to the skin color recognition sensor 14. It can be understood that one end of the light guide post 28 extends out of the end face of the light outlet 21 and contacts the skin, and the other end is connected to the skin color recognition sensor 14 of the host 1; the skin color recognition sensor 14 is electrically connected to the main control board 13. After the main unit 1 starts working, each time the light outlet 21 moves, the white LED on the skin tone recognition sensor 14 activates, transmitting white light through the light guide column 28 to illuminate the skin. The primary color light reflected by the skin is transmitted to the skin tone recognition sensor 14 via the light guide column 28. Based on the principle of three primary colors, the skin tone recognition sensor 14 converts the red, green, and blue light signals into corresponding frequency data and transmits them to the main control board 13. After reading the frequency information, the main control board 13 determines the skin color type and then issues a power level command to adjust the light intensity of the flash mechanism 22, achieving different light power outputs for different skin tones. This skin tone adaptive light power adjustment prevents the problem of strong light burning the skin when the skin is darker, and weak light failing to achieve the desired cosmetic effect when the skin is lighter, improving both the phototherapy effect and safety. Since the light guide column 28 is integrated into the output head 2, there is no need to recalibrate the skin tone detection component when replacing the output head 2, ensuring detection stability.

[0044] This embodiment provides a high-intensity pulsed light instrument with interchangeable output effects. By integrating the flash mechanism and cooling mechanism into a detachable output head, the output effect can be adjusted by changing the output head with different light output size, flash effect, and cooling effect. There is no need to install accessories to adjust the light output area, which would interfere with the cooling mechanism, thus maintaining the reliability and effectiveness of the cooling effect and avoiding thermal damage to the user. Moreover, the interchangeable output head design is suitable for use scenarios where one person uses one output head, ensuring hygiene for multiple users.
