Description

Technical Field

[0001] This utility model relates to the field of television eye protection technology, specifically to a television blue light protection eye protection device. Background Technology

[0002] Blue light is a high-energy short-wavelength light in the visible light spectrum. It can easily penetrate the lens of the eye and reach the retina, causing photochemical damage to the eye as a whole. It rapidly accelerates the oxidation process in the macula of the eye, causing great harm to the eye and leading to symptoms such as dry eyes, eye irritation, and eye pain.

[0003] Existing televisions retain a significant amount of blue light in their backlight artificial light source. While this blue light plays a crucial role in screen display and image generation, prolonged exposure to high levels of blue light can cause eye discomfort and even potential damage. This explains why televisions cause eye fatigue after extended use. Furthermore, some users, especially children, like to sit very close to the television screen, putting excessive strain on their eyes and keeping the eye muscles in a state of tension without rest. Over time, when looking at distant objects, the eye muscles cannot relax and may even spasm, ultimately leading to decreased vision. Therefore, this solution provides a blue light filtering eye protection device for televisions to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a blue light protection device for televisions is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A blue light blocking eye protection device for televisions includes a television casing. A display screen is fixedly installed at the front end of the television casing. A reflective layer is provided on the outer end of the display screen. A blue light absorbing sheet is provided on the outer end of the reflective layer. An anti-blue light film is provided on the outer end of the blue light absorbing sheet. A wear-resistant layer is provided on the outer end of the anti-blue light film. Lifting mechanisms are fixedly installed on both the left and right sides of the rear end of the television casing. An automatic roller shutter box is fixedly installed at the top of the television casing. A pull rod is provided at the lower exit of the automatic roller shutter box. A human body detector is fixedly installed at the top of the automatic roller shutter box.

[0007] Preferably, a pair of mounting brackets are fixedly connected to the middle of the rear end of the television casing, and several sets of reinforcing plates are provided on the inner side of the two mounting brackets.

[0008] Preferably, the automatic roller shutter box is internally equipped with a roller shutter and a return spring, with one end of the roller shutter fixedly connected to the return spring and the other end fixedly connected to the pull rod.

[0009] Preferably, the lifting mechanism includes a lifting motor, a mounting frame, and a threaded screw. The lifting motor and the mounting frame are both fixedly installed at the rear end of the television casing. The threaded screw is rotatably installed inside the mounting frame. The output end of the lifting motor passes through the interior of the mounting frame and is fixedly connected to a first bevel gear.

[0010] Preferably, a baffle is fixedly connected to the upper inner wall of the mounting frame, and the middle part of the baffle is rotatably connected to the surface of the threaded screw.

[0011] Preferably, the threaded screw has a movable block threadedly connected to its surface. The movable block is located on the lower side of the baffle, and a connecting frame is fixedly connected to one end of the movable block. A fixing rod is fixedly connected to the front end of the connecting frame, and the other end of the fixing rod is fixedly connected to the pull rod.

[0012] Compared with the prior art, this utility model proposes a blue light blocking and eye protection device for televisions, which has the following beneficial effects:

[0013] 1. In this utility model, the outer surface of the display screen is provided with a reflective layer, a blue light absorbing sheet, an anti-blue light film, and a wear-resistant layer. The reflective layer reflects blue light, which is then absorbed and filtered by the blue light absorbing sheet, especially shorter wavelength blue light, reducing the possibility of it entering the eyes. Finally, the anti-blue light film weakens the blue light, reducing its harm to the eyes while maintaining the image quality of the screen. The reflective layer, blue light absorbing sheet, and anti-blue light film work together to improve the overall blue light blocking effect and enhance the protection of the eyes. Simultaneously, the wear-resistant layer provides wear and scratch resistance, improving the scratch and wear resistance of the display screen surface.

[0014] 2. This utility model includes a human body detector, which contains an infrared human body detector. It identifies the human body by detecting the infrared radiation (heat) emitted by the human body, thereby determining whether a human body is present and the distance between the current position and the television. When a human body gets too close to the television screen, a reminder is issued through the display screen. If the reminder is ineffective, a lifting mechanism moves a lever down, which in turn moves the automatic roller blind inside the automatic roller blind box, causing the roller blind to block the television screen, thus preventing the user from watching and reducing the risk of myopia caused by watching television too closely for too long, achieving the effect of eye protection.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0023] Reference Figure 1-5As shown, a blue light protection device for televisions includes a television casing 1. A display screen 2 is fixedly installed at the front end of the television casing 1. A reflective layer 201 is provided on the outer end of the display screen 2. A blue light absorbing sheet 202 is provided on the outer end of the reflective layer 201. An anti-blue light film 203 is provided on the outer end of the blue light absorbing sheet 202. A wear-resistant layer 204 is provided on the outer end of the anti-blue light film 203. Lifting mechanisms 3 are fixedly installed on both the left and right sides of the rear end of the television casing 1. An automatic roller shutter box 4 is fixedly installed on the top of the television casing 1. A pull rod 401 is provided at the lower outlet of the automatic roller shutter box 4. A human body detector 5 is fixedly installed on the top of the automatic roller shutter box 4. The outer side of the display screen 2 in this device is provided with a reflective layer 201, a blue light absorbing sheet 202, an anti-blue light film 203, and a wear-resistant layer 204. The reflective layer 201 reflects blue light, and then the blue light absorbing sheet 202 absorbs and filters the blue light, especially the shorter wavelength blue light, reducing the possibility of it entering the eyes. Finally, the anti-blue light film 203 further weakens the blue light, reducing the damage of blue light to the eyes, while maintaining the image quality of the screen. Through the cooperation of the reflective layer 201, the blue light absorbing sheet 202, and the anti-blue light film 203, the overall anti-blue light effect can be improved, enhancing the protection of human eyes. Meanwhile, the wear-resistant layer 204 has wear-resistant and scratch-resistant effects, which can improve the scratch-resistant and wear-resistant effect of the surface of the display screen 2. At the same time, a human body detector 5 is set up, which has an infrared human body detector inside. It identifies the human body by detecting the infrared radiation (heat) emitted by the human body, and then determines whether there is a human body and the distance between the current position and the TV. When the human body is too close to the TV screen, the display screen 2 will issue a reminder. If the reminder is ineffective, the lifting mechanism 3 will drive the pull rod 401 to move down. The pull rod 401 will then drive the roller blind inside the automatic roller blind box 4, so that the roller blind will block the TV screen, thereby preventing the user from watching. This reduces the risk of myopia caused by watching TV too closely for too long, and achieves the effect of eye protection.

[0024] Specifically, in this embodiment, a pair of mounting brackets 6 are fixedly connected to the middle of the rear end of the television casing 1, and several sets of reinforcing plates 7 are provided on the inner side of the two mounting brackets 6. The television casing 1 can be mounted on a wall or other location using the mounting brackets 6.

[0025] Specifically, in this embodiment, the automatic roller shutter box 4 is internally equipped with a roller shutter and a return spring. One end of the roller shutter is fixedly connected to the return spring, and the other end is fixedly connected to the pull rod 401. The structure and working principle of the automatic roller shutter box 4 are similar to those of a measuring tape. When the roller shutter is pulled down by the pull rod 401, a force is applied to the return spring, which in turn causes the return spring to have a rebound force on the roller shutter. The rebound force of the return spring, in conjunction with the resetting of the lifting mechanism, allows the roller shutter to be rolled back quickly and smoothly, preventing it from getting stuck and ensuring the rapid retraction and ease of use of the roller shutter.

[0026] Specifically, in this embodiment, the lifting mechanism 3 includes a lifting motor 301, a mounting frame 302, and a threaded screw 306. Both the lifting motor 301 and the mounting frame 302 are fixedly mounted on the rear end of the television casing 1. The threaded screw 306 is rotatably mounted inside the mounting frame 302. The output end of the lifting motor 301 penetrates into the mounting frame 302 and is fixedly connected to a first bevel gear 303. The upper end of the first bevel gear 303 meshes with a second bevel gear 304, which is fixedly mounted on the upper end of the threaded screw 306. When a person gets too close to the television screen, a warning is issued via the display screen 2. If the warning is ineffective, the lifting mechanism 3 is activated, driving the first bevel gear 303 to rotate via the lifting motor 301. The first bevel gear 303 then drives the second bevel gear 304 to rotate, and the second bevel gear 304 then drives the threaded screw 306 to rotate.

[0027] Specifically, in this embodiment, a baffle 305 is fixedly connected to the upper inner wall of the mounting frame 302, and the middle part of the baffle 305 is rotatably connected to the surface of the threaded screw 306. The baffle 305 is used to limit the movement of the moving block 307, thereby protecting the safety of the two bevel gears and preventing the bevel gears from being impacted by the moving block 307.

[0028] Specifically, in this embodiment, a movable block 307 is threadedly connected to the surface of the threaded screw 306. The movable block 307 is located on the lower side of the baffle 305, and a connecting frame 308 is fixedly connected to one end of the movable block 307. A fixing rod 309 is fixedly connected to the front end of the connecting frame 308, and the other end of the fixing rod 309 is fixedly connected to the pull rod 401. When the threaded screw 306 rotates, it drives the movable block 307 to move up and down on the surface of the threaded screw 306. When the movable block 307 moves downward, it drives the pull rod 401 to move downward through the connecting frame 309. The pull rod 401 then drives the roller blind in the automatic roller blind box 4 to pull down, so that the roller blind blocks the screen of the TV, thereby preventing the user from watching and reducing the risk of myopia caused by watching TV too closely for too long, achieving the effect of eye protection.

[0029] The working principle of this invention is as follows: The outer side of the display screen 2 of this device is provided with a reflective layer 201, a blue light absorbing sheet 202, an anti-blue light film 203, and a wear-resistant layer 204. When the television is in use, the light emitted from the light source at the back panel passes through the display screen and then sequentially through the reflective layer 201, the blue light absorbing sheet 202, the anti-blue light film 203, and the wear-resistant layer 204. The reflective layer 201 reflects the blue light, and then the blue light absorbing sheet 202 absorbs and filters the blue light, especially shorter wavelengths, reducing the possibility of it entering the eyes. Finally, the anti-blue light film 203 further weakens the blue light, reducing its harm to the eyes while maintaining the image quality of the screen. The reflective layer 201, the blue light absorbing sheet 202, and the anti-blue light film 203 work together to improve the overall blue light protection effect and enhance the protection of the eyes. Simultaneously, the wear-resistant layer 204 has wear-resistant and scratch-resistant properties, improving the scratch and wear resistance of the display screen 2 surface.

[0030] Meanwhile, a human body detector 5 is installed, which contains an infrared human body detector. It identifies the human body by detecting the infrared radiation (heat) emitted by the human body, and then determines whether the human body is present and the distance between the current position and the television. When the human body gets too close to the television screen, a reminder is issued through the display screen 2. If the reminder is ineffective, the lifting mechanism 3 is activated. The lifting motor 301 drives the first bevel gear 303 to rotate, which in turn drives the second bevel gear 304 to rotate. The second bevel gear 304 in turn drives the threaded screw 306 to rotate, which in turn drives the moving block 307 to move up and down on the surface of the threaded screw 306. When the moving block 307 moves downward, the connecting bracket 309 drives the pull rod 401 to move downward. The pull rod 401 in turn drives the roller blind in the automatic roller blind box 4 to pull down, so that the roller blind blocks the television screen, thereby preventing the user from watching and reducing the risk of myopia caused by watching television too closely for too long, thus achieving the effect of eye protection.
