[0002] In modern life and industrial production, ultraviolet (UV) and infrared (IR) radiation have a significant impact on people's lives and the operation of equipment. UV radiation has strong radioactivity, and long-term exposure to it can damage human skin and accelerate the aging of object surfaces. Infrared radiation, on the other hand, generates a large amount of heat, leading to increased indoor temperatures and increased energy consumption of cooling equipment such as air conditioners.

[0003] Currently, there are some products on the market designed to block ultraviolet and infrared rays, such as traditional heat-insulating glass. However, these products have certain limitations. Traditional heat-insulating glass mainly blocks infrared rays through methods such as coatings, but its effectiveness in blocking ultraviolet rays is poor, and it cannot be flexibly adjusted according to actual needs.

[0004] Therefore, a new type of ultraviolet and infrared photothermal regulation and isolation device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultraviolet and infrared photothermal regulation and isolation device to solve the problem that traditional heat-insulating glass mainly blocks infrared rays through coating and other methods, but its isolation effect on ultraviolet rays is not good and it cannot be flexibly adjusted according to actual needs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] For examples, please refer to Figure 1 - Figure 2 The ultraviolet and infrared photothermal regulation and isolation device shown in the figure includes an outer frame 1, and a photothermal regulation component is provided inside the outer frame 1 for automatically adjusting the photothermal transmittance.

[0022] The photothermal regulating component includes a photochromic molecule 21 and a thermochromic polymer 22. The photochromic molecule 21 is grafted onto the thermochromic polymer 22 chain to form a first film 2, which is disposed within the outer frame 1. When ultraviolet or infrared rays irradiate the first film 2, the photochromic molecule 21 is grafted onto the thermochromic polymer 22 chain, achieving a "photo-thermal" synergistic response. When irradiated by ultraviolet rays, spiropyran changes color and absorbs light energy. At the same time, PNIPAM undergoes a cloud point transition due to the increase in temperature, thereby absorbing and scattering more light, reducing the transmittance of ultraviolet and infrared rays, and enhancing the light-blocking effect. When there is no light, the temperature decreases, PNIPAM returns to transparency, the material's light transmittance increases, and the light transmittance is improved.

[0023] An insulating component is installed inside the outer frame 1 to further isolate ultraviolet and infrared rays;

[0024] The insulating component includes an ultraviolet absorbing layer 31 and an infrared reflective layer 32, which are bonded together to form a second film 3. The second film 3 is disposed inside the outer frame 1 and on the side wall of the first film 2. When light shines on the second film 3, titanium dioxide converts ultraviolet light into heat energy and dissipates it. The aluminum foil has a high reflectivity and reflects infrared light back, thereby reducing the transmission of infrared light and achieving effective regulation and isolation of ultraviolet and infrared light.

[0025] The outer frame 1 includes a frame 11 and a limiting cover 16. A fixing block 14 is fixedly installed inside the frame 11. A first transparent glass 13 is inserted into the frame 11. Glass glue is applied between the first transparent glass 13 and the fixing block 14. A rectangular pressure plate 12 is bonded to the frame 11 with glass glue. The rectangular pressure plate 12 is attached to the side wall of the first transparent glass 13. A first spring clamping seat 15 for clamping the first film 2 is fixedly installed inside the frame 11. A second spring clamping seat 19 for clamping the second film 3 is fixedly installed on the left side inside the limiting cover 16. A second transparent glass 110 is bonded to the right side inside the limiting cover 16 with glass glue.

[0026] The first film 2 is placed inside the first spring clamping seat 15 in the frame 11 and clamped by the first spring clamping seat 15. Then, glass glue is sprayed to fix the right end of the first transparent glass 13 to the left side of the fixing block 14. Glass glue is sprayed again to fix the rectangular pressure plate 12 inside the frame 11 and limit the left end of the first transparent glass 13, thus completing the fixation of the first transparent glass 13. The second film 3 is placed inside the second spring clamping seat 19 in the limiting cover 16 and clamped by the second spring clamping seat 19. Glass glue is sprayed to fix the second transparent glass 110 to the right end of the limiting cover 16. The limiting cover 16 is attached to the frame 11. The four sets of bolts 18 are rotated in the threaded holes 17 in sequence and the bolts 18 are threaded into the frame 11, thus combining the frame 11 and the limiting cover 16 to form the outer frame 1. The installed outer frame 1 is installed at the position where light and heat regulation and isolation are required.

[0027] Working principle:

[0028] First, place the first film 2 inside the first spring clamping seat 15 in the frame 11 and clamp the first film 2 using the first spring clamping seat 15. Then, spray glass glue to fix the right end of the first transparent glass 13 to the left side of the fixing block 14. Spray glass glue again to fix the rectangular pressure plate 12 inside the frame 11 and limit the left end of the first transparent glass 13, thus completing the fixation of the first transparent glass 13. Place the second film 3 inside the second spring clamping seat 19 in the limiting cover 16 and clamp the second film 3 using the second spring clamping seat 19. Spray glass glue to fix the second transparent glass 110 to the right end of the limiting cover 16. Attach the limiting cover 16 to the frame 11. Rotate the four sets of bolts 18 in the threaded holes 17 in sequence and thread the bolts 18 into the frame 11, thus combining the frame 11 and the limiting cover 16 to form the outer frame 1. Install the installed outer frame 1 at the location where light and heat regulation and isolation are required.

[0029] In practical use, when ultraviolet or infrared rays irradiate the first film 2, the photochromic molecule 21 is grafted onto the thermochromic polymer chain 22, achieving a "light-heat" synergistic response. When irradiated by ultraviolet rays, spiropyran changes color and absorbs light energy, while PNIPAM undergoes a cloud point transition due to temperature increase, thereby absorbing and scattering more light, reducing the transmittance of ultraviolet and infrared rays, and enhancing the light-blocking effect. When there is no light, the temperature decreases, PNIPAM returns to transparency, the material's light transmittance increases, and the light transmittance is improved. Through the photothermal adjustment component, the problem of traditional heat-insulating glass mainly blocking infrared rays through coating and other methods, but having poor isolation effect on ultraviolet rays and being unable to be flexibly adjusted according to actual needs is solved.

[0030] The isolation element is designed to further isolate ultraviolet and infrared rays; when light shines on the second film 3, titanium dioxide converts ultraviolet rays into heat energy and dissipates it; the aluminum foil has a high reflectivity, which reflects infrared rays back, thereby reducing the transmission of infrared rays and achieving effective regulation and isolation of ultraviolet and infrared rays.
