[0030] Referring to Figures 1 to 5 As shown in the drawings, the present embodiment discloses an output effect replaceable intense pulsed light instrument, which comprises a host computer 1 and an output head 2 detachably connected to the host computer 1; one end surface of the output head 2 is provided with a light outlet 21, and the output head 2 is provided with a connecting plate 24, a flash mechanism 22 and a cooling mechanism 23 electrically connected to the connecting plate 24; the flash mechanism 22 is arranged opposite to the light outlet 21 and is used for outputting intense pulsed light; the cooling mechanism 23 is used for reducing the temperature of the end surface where the light outlet 21 of the output head 2 is located; the connecting plate 24 extends from the inside of the output head 2 to the side away from the light outlet 21, and the output end of the host computer 1 is provided with an interface 11, and the connecting plate 24 is plugged into the interface 11 to be electrically connected or separated from the host computer 1.

[0031] In implementation, the user can select a suitable output head 2 according to the target area of beauty treatment and the characteristics of the skin of the target area and the object, for example, a small-area strong pulsed light output head 2 is used to remove hair on the fingers, and for example, a large-area strong pulsed light output head 2 is used to remove hair on the limbs. Then, the suitable output head 2 is installed at the output end of the main machine 1, the connecting plate 24 is electrically connected to the main machine 1, and the main machine 1 controls the output head 2 to output the preset flash effect and cooling effect. The user can also replace the output head 2 in the case of user change to select the output head 2 used by the user.

[0032] The output effect of the strong pulsed light instrument of the embodiment can be changed. By integrating the flash mechanism 22 and the cooling mechanism 23 in the detachable output head 2, the output head 2 with different light outlet 21 sizes, flash effects, and cooling effects can be replaced to adjust the output effect, which is beneficial to meet the precise beauty and skin care needs of the user, such as removing excess hair, skin rejuvenation, acne and wrinkle removal, treating acne, treating capillary and reticular veins, treating fresh red nevus, treating scars, etc. At the same time, different output heads 2 with different light outlet 21 areas can be selected during use, without assembling accessories to adjust the light outlet area and interfering with the cooling mechanism 23, maintaining the reliability and effectiveness of the cooling effect, avoiding user thermal damage. The replaceable design of the output head 2 is suitable for the use scenario of one person one output head 2, which guarantees the hygiene of multiple users, so that family members or small group members can share one main machine 1 and match the exclusive output head 2 selected according to their own needs, avoiding cross infection. In addition, the output head 2 can be replaced when the output head 2 is used for a long time or damaged, which can increase the service life of the strong pulsed light instrument and improve its market competitiveness.

[0033] In further embodiments, the end of the output head 2 away from the light outlet 21 is provided with a plurality of buckles 25, and the output end of the main machine 1 is provided with a buckle slot 12 corresponding to the buckle 25, and the buckle 25 and the buckle slot 12 are connected or separated. Through the mechanical connection structure of the buckle 25 of the output head 2 and the buckle slot 12 of the main machine 1, the output head 2 and the main machine 1 are quickly physically fixed, and the plug-in of the connecting plate 24 and the interface 11 of the main machine 1 is matched to complete the mechanical connection and electrical connection of the output head 2 and the main machine 1, 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 board 24 to drive the flash mechanism 22 to output light energy according to the preset voltage and flash time. More specifically, the connecting board 24 is provided with detection resistors of different resistances, and the resistances of the detection resistors on different output heads 2 are different; after the host 1 is connected to the output head 2, the main control board 13 detects the voltage of the connecting board 24, and because different detection resistors correspond to different voltages, the host 1 can obtain the type and parameters of the output head 2 according to the detected voltage value; after the host 1 obtains the voltage value of the output head 2, the voltage of the energy storage capacitor on the connecting board 24 is changed or the corresponding pulse width is outputted through the change of the PWM parameter, so as to adjust the voltage or flash time of the lamp tube 222, and then the light output corresponds to the corresponding light energy, on the other hand, the main control board 13 can control the single-chip step-down converter on the connecting board 24 to adjust the power supply voltage of the cooling fin 232 and change the cooling power, so that the cooling effect and the light energy are matched. The arrangement of the main control board 13 and the connecting board 24 realizes the automatic identification of the type of the output head 2, and can synchronously adapt the flash and cooling parameters without manual adjustment, which is convenient to operate.

[0035] In a further embodiment, the interface 11 is electrically connected with the main control board 13; the connecting board 24 is provided with a gold finger, which is used for plugging with the interface 11 and realizing the electrical connection between the connecting board 24 and the main control board 13. It can be understood that the gold finger is a conductive contact piece assembly on the electronic hardware, which is composed of gold yellow contact pieces arranged like fingers, and the surface realizes signal transmission through gold plating or tin plating process, has the functions of anti-oxidation and reducing contact resistance, and can be used for plugging with the interface 11. Compared with the traditional wire connection, the plugging structure of the gold finger and the interface 11 has smaller contact resistance and higher power transmission efficiency, and can avoid the problem of unstable power supply of components caused by poor contact; at the same time, the plugging mode is convenient to operate, and when the user replaces the output head 2, the electrical connection can be completed only by plugging the gold finger with the interface 11, without additional wiring, so that the output head 2 is detachable and plug and play.

[0036] The traditional intense pulsed light instrument adopts a single filter 223 integrated in the main machine 1 and cannot be replaced, so it can only set a wide band of full coverage, increasing the risk of damage to the skin by invalid band intense pulsed light. Therefore, the intense pulsed light instrument of the embodiment is provided with an independent flash mechanism 22 on each output head 2, so that the user can replace the filter 223 by replacing the output head 2, achieve the expected beauty purpose while reducing the damage to the skin by invalid intense pulsed light of the required external band and excessive heat generated thereby. More specifically, the flash mechanism 22 of the embodiment comprises a bracket 221, a lamp tube 222, a filter 223 and a reflector 224; the reflector 224 is arranged in the output head 2, and the opening end of the reflector 224 is arranged opposite the light outlet 21; the filter 223 is arranged at the opening end of the reflector 224, and the lamp tube 222 is arranged 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 main machine 1 is triggered, the xenon gas in the lamp tube 222 is ionized to release intense pulsed light, the reflector 224 reflects the light 360° to the light outlet 21 to increase the light energy, and the light is filtered by the filter 223 to remove the invalid band and then output through the light outlet 21.

[0037] In a further embodiment, the cooling mechanism 23 comprises a heat sink 231, a refrigeration sheet 232 and a conduction piece 233; the heat sink 231 is arranged parallel to the flashing mechanism 22, the refrigeration sheet 232 is arranged at one end of the heat sink 231 close to the light outlet 21, and the refrigeration sheet 232 is electrically connected to the connecting plate 24; the conduction piece 233 is arranged on the end face of the output head 2 where the light outlet 21 is located, and is connected to the refrigeration sheet 232. More specifically, the refrigeration sheet 232 works on the principle of semiconductor temperature difference refrigeration, and is internally composed of a plurality of P-type semiconductors and N-type semiconductors arranged alternately, and obtains power supply from the host 1 through the connecting plate 24, and the connecting plate 24 is electrically connected to the main control board 13, and the main control board 13 is provided with a single-chip step-down converter to provide an adaptive working voltage for the refrigeration sheet 232; after being powered on, the internal electron flow of the refrigeration sheet 232 obtains energy, absorbs heat when passing through the P-type semiconductor from the negative electrode, and releases heat when reaching the N-type semiconductor, and the heat is transferred from one side to the other side every time a PN semiconductor module is passed through, forming a cold end and a hot end; preferably, the cold end and the hot end of the refrigeration sheet 232 are respectively composed of two pieces of insulating ceramic sheets, the cold end of the refrigeration sheet 232 is tightly connected to the conduction piece 233 to transfer coldness to the conduction piece 233 to achieve cooling, and the hot end is connected to the heat sink 231 to conduct heat out. The conduction piece 233 is arranged on the end face where the light outlet 21 is located, and can contact the user's skin to bring the user a cool experience; after the fan of the host 1 is started, the air flow can take away the heat of the heat sink 231 to achieve cooling of the conduction piece 233, thereby reducing the temperature of the end face where the light outlet 21 is located, and achieving the cold compress effect; in addition, arranging the heat sink 231 parallel to the flashing mechanism 22 can avoid mutual interference of heat between the two, ensure the heat dissipation efficiency of the hot end of the refrigeration sheet 232, and further maintain the stability of the cooling effect.

[0038] Preferably, the heat sink 231 is made of a metal material with good heat conduction performance; the heat sink 231 is provided with a plurality of heat dissipation fins 2311, and gaps exist between adjacent heat dissipation fins 2311. The gaps between adjacent heat dissipation fins 2311 increase the surface area of the heat sink 231, and further increase the heat dissipation area thereof; when the air output by the host 1 acts on the heat sink 231, the air can timely take away the heat on the heat sink 231 to ensure the cold compress effect of the cold compress sheet.

[0039] It can be understood that during the production stage, the light output area, cooling effect and flashing effect of each output head 2, i.e. the area of the light outlet 21, the type of the conduction piece 233 and the energy of the flashing mechanism 22, can be set according to actual needs, user preference and market demand.

[0040] In a further embodiment, the conducting member 233 is a cold compress or sapphire; the conducting member 233 is arranged side by side with the light outlet 21 or covers the light outlet 21. More specifically, the cold compress is made of a metal material with good thermal conductivity; the sapphire is made of an optical-grade sapphire crystal α-Al 2 O 3 material. Referring to Figure 4 The conducting member 233 of the output head 2 shown in the figure is a cold compress, which can quickly receive the cold energy transmitted by the cold end of the refrigeration sheet 232 and uniformly distribute it around the light outlet 21, and is arranged side by side with the light outlet 21, which can directly contact the skin to achieve cooling; referring to Figure 5 The conducting member 233 of the output head 2 shown in the figure is a sapphire, which has high thermal conductivity and light transmission, and can receive cold energy for skin cooling without affecting the penetration of intense pulsed light to the target area of the skin. Therefore, the sapphire can be arranged to cover the light outlet 21, and its area is larger than that of the light outlet 21, achieving a large-area cold compress effect. In specific implementation, users can choose output heads 2 with different conducting members 233 according to different use requirements. More specifically, the cold compress has low cost and fast cooling speed, and is suitable for areas with low light transmission requirement or small target area; the sapphire has good light transmission and high chemical stability, and is suitable for scenes that require intense pulsed light penetration or large target area; and both are directly adapted to the refrigeration sheet 232, so that the type of conducting member 233 can be switched by replacing the output head 2 without additional adjustment of the cooling mechanism 23.

[0041] In a further embodiment, the output head 2 is provided with an air inlet 26a, a first air outlet 26b and a second air outlet 26c on the end face away from the light outlet 21, and the output end of the main machine 1 is provided with an air outlet hole 15 and an air inlet hole 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 arranged opposite to the radiator 231; the air inlet 26a is used to guide the airflow into the output head 1, part of the airflow flows through the flash mechanism 22 and then leaves the output head 2 through the first air outlet 26b, and part of the airflow flows through the radiator 231 and then leaves the output head 2 through the second air outlet 26c. More specifically, referring to Figure 1As shown, when the output head 2 is connected to the host 1, the second air outlet 26c is exposed outside the host 1. It can be understood that the host 1 is provided with a fan. When the host 1 is working, the internal fan is started, and the external cold air enters the host 1 through the air inlet 16 of the host 1, and then flows into the output head 2 through the air inlet 26a of the output head 2. The airflow entering the output head 2 is divided into two paths: one path flows to the first air outlet 26b after passing through the flash mechanism 22, and then flows back to the host 1 through the air outlet 15 of the host 1 or is discharged, which can carry away the heat generated by the lamp tube 222 of the flash mechanism 22; the other path flows to the second air outlet 26c after passing through the radiator 231, and is directly discharged outside the output head 2, which can carry away the heat transferred to the radiator 231 by the hot end of the refrigeration sheet 232, thereby achieving heat dissipation of the flash mechanism 22 and the radiator 231. The airflow shunting design makes the heat dissipation paths of the flash mechanism 22 and the radiator 231 independent of each other, avoids the superposition of the heat of the lamp tube 222 and the heat of the radiator 231, and greatly improves the heat dissipation efficiency; the first air outlet 26b corresponds to the air outlet 15 of the host 1, and the airflow power can be enhanced by the fan of the host 1; the second air outlet 26c directly discharges hot air, reducing the retention of hot air in the output head 2; and the air inlets 26a and the first air outlets 26b are linearly distributed along the length direction of the flash mechanism 22, and the second air outlet 26c is arranged opposite to the radiator 231, so that the airflow covers uniformly in the output head 2, ensuring that there is no dead angle for heat dissipation.

[0042] In further embodiments, the output head 2 is further provided with an induction sheet 27, which is electrically connected to the connecting plate 24 and arranged at one end of the flash mechanism 22 close to the light outlet 21. More specifically, the induction sheet 27 is provided with a through hole in the center, so that the induction sheet 27 is arranged in a frame shape around the filter 223 of the flash mechanism 22, and then the strong pulsed light is sequentially output to the surface of the user's skin through the filter 223, the through hole and the light outlet 21. The induction sheet 27 is electrically connected to the main control board 13 of the host 1 through the connecting plate 24, and is arranged close to the light outlet 21. When the light outlet 21 of the output head 2 is attached to the skin, the induction sheet 27 contacts the skin and detects the skin contact signal, and transmits the signal to the host 1 through the connecting plate 24. After the host 1 receives the valid contact signal, the flash mechanism 22 is allowed to trigger the flash. If the skin contact signal is not detected or the contact is not close enough, the host 1 prohibits the flash mechanism 22 from working, so as to avoid the mis-triggering of the strong pulsed light and causing harm to the human body. Therefore, the arrangement of the induction sheet 27 not only can be attached to the skin during use, but also avoids interference with the flash mechanism 22, and effectively avoids the risk of mis-output of the strong pulsed light in a non-contact state, thereby improving the safety of the product in use.

[0043] In a further embodiment, the output head 2 is further provided with a light guide column 28 extending from the end face where the light outlet 21 is located to the other end; the main machine 1 is provided with a skin color recognition sensor 14, and when the output head 2 is connected to the main machine 1, the light guide column 28 is electrically connected to the skin color recognition sensor 14. It can be understood that one end of the light guide column 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 main machine 1; the skin color recognition sensor 14 is electrically connected to the main control panel 13. After the main machine 1 works, the white LED light on the skin color recognition sensor 14 works every time the light outlet 21 moves once, and the white light is transmitted through the light guide column 28 to illuminate the skin, and the original color light reflected by the skin is transmitted to the skin color recognition sensor 14 through the light guide column 28; the skin color recognition sensor 14 converts the red, green and blue light signals into corresponding frequency data according to the three primary color principle and transmits them to the main control panel 13; after the main control panel 13 reads the frequency information, it judges the skin color type, and then issues a gear command to adjust the light intensity of the flash mechanism 22, realizing the adaptation of different skin colors to different light power outputs. By adjusting the light power through skin color adaptation, the problem of skin burn by strong light when the skin color is dark and weak light that cannot achieve the beauty effect when the skin color is light can be prevented, and the light therapy effect and safety can be improved; the light guide column 28 is integrated in the output head 2, so that when the output head 2 is replaced, the skin color detection component does not need to be recalibrated, ensuring the detection stability.

[0044] The embodiment provides an intense pulsed light instrument with replaceable output effect, by integrating the flash mechanism and the cooling mechanism in the detachable output head, so that replacing the output head with different light outlet sizes, flash effects and cooling effects can realize the adjustment of the output effect, without assembling accessories to adjust the light emitting area and interfering with the cooling mechanism, thereby maintaining the reliability and effectiveness of the cooling effect and avoiding user thermal damage; and the replaceable design of the output head adapts to the use scene of one person one output head, thereby ensuring the hygiene degree of multiple people using.

[0045] The above only further illustrates the technical content of the present application by way of examples, so that the reader can more easily understand, but does not represent that the embodiments of the present application are limited to this, any technical extension or re-creation made according to the present application is protected by the present application.
