Description

An automatic light-sensing lifting device for curtains Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to an automatic light-sensing lifting device for curtains. Background Technology

[0002] Curtains are a common household item, serving both decorative and functional purposes, including sunshade, heat insulation, and light regulation. Existing curtains are mainly divided into two types: manual and electric. Manual curtains include manual opening and closing curtains and manual beaded roller blinds, while electric curtains include electric opening and closing curtains and electric roller blinds. Whether manual or electric, curtains require manual operation and cannot automatically rise or fall according to the intensity of external light.

[0003] A search revealed Chinese patent CN218683679U, which discloses an automatic light-sensing lifting device, including an electric lifting curtain. The electric lifting curtain is fixedly installed on the inner wall of a wall. A box is located at the top of the electric lifting curtain, and the bottom of the box is fixedly connected to the surface of the wall. A controller is located at the bottom of the inner cavity of the box. A partition is fixedly connected inside the box, and a light sensor is located at the top of the partition. A transparent cover is fitted over the surface of the box, and a square frame is fixedly connected to the surface of the box, with the surface of the square frame contacting the inner wall of the transparent cover. The output of the light sensor is electrically connected to the input of the controller, and the output of the controller is electrically connected to the input of the electric lifting curtain. This technical solution mainly relies on the light sensor to detect light and send a detection signal to the controller. After receiving the information, the controller starts the electric lifting curtain, which automatically rolls up. When the light sensor no longer detects light, the electric lifting curtain unfolds. However, this solution still has shortcomings in practical use:

[0004] The light sensor is fixedly installed inside the box, and the light it senses only comes from the area above the box. If the light in this area cannot accurately represent the lighting conditions of the entire room, it may cause the curtains to be controlled in a way that does not meet the actual needs. Since the position of the light sensor is fixed, once it is installed, its sensing position cannot be adjusted. Summary of the Invention

[0005] This utility model provides an automatic light-sensing lifting device for curtains, which solves the problem in related technologies where the light sensor is fixedly installed in the box and the sensing position cannot be adjusted, which may cause the light it senses to be unable to accurately represent the light conditions of the entire room, thus making the curtain control not meet the actual needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic light-sensing lifting device for curtains, comprising a housing containing an electric curtain;

[0007] A frame is mounted on the housing, and a rotating air blowing assembly is disposed inside the frame. Photosensitive components are mounted at both ends of the rotating air blowing assembly. A driving component is mounted on the frame to drive the rotating air blowing assembly to move along its length and to cause the photosensitive components to flip.

[0008] An air supply assembly is mounted on the frame to supply air to the rotating air blowing assembly, and the rotating air blowing assembly is used to blow gas toward the photosensitive assembly.

[0009] Preferably, the rotating air blowing assembly includes a hollow slider, which is slidably disposed within the frame and driven to move by a drive component. A horizontally arranged rotating rod is rotatably connected to the hollow slider. Two photosensitive components are respectively installed at both ends of the rotating rod. A rack is installed on the side of the frame, and a gear that meshes with the rack is fixed on the rotating rod.

[0010] Preferably, the photosensitive component includes a transparent tube and a light sensor. The two transparent tubes are respectively installed at both ends of the rotating rod. The light sensor is installed inside the transparent tube. An opening is formed on the transparent tube, and a sealing plug is sealed inside the opening.

[0011] Preferably, the hollow slider has a cavity inside, and air holes communicating with the cavity are opened on both sides of the hollow slider, with the air holes on both sides of the hollow slider facing the two transparent cylinders respectively.

[0012] Preferably, the air supply assembly includes a miniature air pump and an air supply hose. Two loading blocks are symmetrically mounted on the housing. The frame is mounted on the two loading blocks. The miniature air pump is mounted on one loading block. The two ends of the air supply hose are respectively connected to the air outlet of the miniature air pump and the bottom of the hollow slider.

[0013] Preferably, the driving component includes an electric slide rail, which is mounted on the top of the frame. The hollow slider is connected to the driving end of the electric slide rail and is driven by the electric slide rail to move along the length of the frame.

[0014] Preferably, a controller is installed at the end of the frame, and the electric curtain, electric sliding rail, and miniature air pump are all electrically connected to the controller.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention places the photosensitive components on both sides of the rotating air blowing component on the frame indoors and outdoors, respectively. In use, the two photosensitive components can sense the outdoor light and indoor light respectively, and then compare them to control the raising and lowering of the electric curtains. This design effectively solves the problem that traditional light sensors can only sense the light in the area above the box and cannot accurately represent the light situation of the entire room. As a result, the raising and lowering of the electric curtains can be controlled more precisely, making them more in line with actual light needs. This improves the accuracy and practicality of electric curtain control and provides users with a more comfortable and reasonable light adjustment environment.

[0017] In summer and winter, the angle of sunlight will change. When the light sensed by the photosensitive component of this invention is lower than the preset threshold, the rotating air blowing component can be driven to move along the length of the frame by the driving component. When the rotating air blowing component moves, it can cause the photosensitive component to flip. This process not only changes the position of the photosensitive component, but also adjusts its angle, so that it can flexibly adapt to different light angles according to seasonal changes, ensuring that the photosensitive component is always in the best light-sensing position, reducing the problem of frequent maintenance or replacement due to inaccurate light sensing caused by seasonal changes.

[0018] During use, dust easily accumulates on the surface of the photosensitive component of this invention. When the rotating air blowing component drives the photosensitive component to flip, gas can be guided into the rotating air blowing component through the air supply component, and then blown onto the photosensitive component through the rotating air blowing component. During the flipping process, the dust on the surface of the photosensitive component is cleaned. This automatic cleaning function does not require manual intervention and can effectively maintain the cleanliness of the surface of the photosensitive component, thereby ensuring that its photosensitive accuracy is always at a high level. This improves the stability and accuracy of the curtain control system, reduces photosensitive errors caused by dust accumulation, and enhances the user experience. Attached Figure Description

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] As shown in Figures 1, 2, 3, 4, and 5, an automatic light-sensing lifting device for curtains includes a housing 1 that houses an electric curtain 101.

[0028] A frame 2 is mounted on the housing 1. A rotating air blowing assembly 3 is disposed inside the frame 2. Photosensitive components 4 are mounted on both ends of the rotating air blowing assembly 3. A drive component is mounted on the frame 2 to drive the rotating air blowing assembly 3 to move along its length and to cause the photosensitive components 4 to flip.

[0029] An air supply assembly 5 is installed on the frame 2 to supply air to the rotating air blowing assembly 3, and the rotating air blowing assembly 3 is used to blow gas toward the photosensitive assembly 4.

[0030] During operation, the drive unit is activated, pushing the rotating air blowing assembly 3 to move within the frame 2, which in turn moves and flips the photosensitive assemblies 4 at both ends, allowing the photosensitive assemblies 4 to sense light at different positions and angles. The air supply assembly 5 supplies air to the rotating air blowing assembly 3, which blows the air towards the photosensitive assemblies 4, cleaning the dust on the surface of the photosensitive assemblies 4 and ensuring their light sensing accuracy. This design allows the photosensitive assemblies 4 to sense light more comprehensively and accurately, and also has an automatic cleaning function, improving the reliability of the device for light sensing and curtain control.

[0031] In a specific embodiment, the rotating air blowing assembly 3 includes a hollow slider 31, which is slidably disposed in the frame 2 and driven to move by a driving component. A horizontally arranged rotating rod 32 is rotatably connected to the hollow slider 31. Two photosensitive components 4 are respectively installed at both ends of the rotating rod 32. A rack 23 is installed on the side of the frame 2, and a gear 33 that meshes with the rack 23 is fixed on the rotating rod 32.

[0032] When the driving component pushes the hollow slider 31 to move along the frame 2, the gear 33 will roll on the rack 23. Since the gear 33 is fixed to the rotating rod 32, the rotating rod 32 will rotate with the rolling of the gear 33, thereby driving the photosensitive components 4 installed at both ends of the rotating rod 32 to flip. The flip angle of the photosensitive components 4 can be precisely controlled, ensuring that the photosensitive components 4 can be adjusted to the appropriate angle to sense light in different usage scenarios, thus improving the adaptability of the device to different lighting environments.

[0033] In a specific embodiment, the photosensitive component 4 includes a transparent tube 41 and a photosensitive sensor 42. The two transparent tubes 41 are respectively installed at both ends of the rotating rod 32. The photosensitive sensor 42 is installed inside the transparent tube 41. An opening is provided on the transparent tube 41, and a sealing plug 43 is sealed inside the opening.

[0034] The light sensor 42 is a key component for sensing light. The transparent tube 41 provides protection for the light sensor 42 and ensures that light can pass through the tube wall and be sensed by the light sensor 42. The sealing plug 43 can prevent dust, moisture and other impurities from entering the interior of the transparent tube 41 and affecting the normal operation of the light sensor 42, thus ensuring the light sensing accuracy and service life of the light sensor 42. During the operation of the device, the light sensor 42 converts the sensed light intensity into an electrical signal, providing data for the subsequent control of the raising and lowering of the electric curtain 101.

[0035] In a specific embodiment, a cavity is provided inside the hollow slider 31, and air holes 34 communicating with the cavity are provided on both sides of the hollow slider 31. The air holes 34 on both sides of the hollow slider 31 face the two transparent cylinders 41 respectively.

[0036] When the air supply component 5 supplies air to the hollow slider 31, the air enters the cavity of the hollow slider 31 and is then blown out from the air blowing holes 34 on both sides, directly blowing onto the surface of the transparent cylinder 41, that is, blowing onto the light sensor 42 installed inside the transparent cylinder 41. As the rotating air blowing component 3 drives the photosensitive component 4 to flip, the continuously blown air can blow off the dust on the surface of the transparent cylinder 41, preventing dust accumulation from affecting the light sensor 42's sensing of light, ensuring that the light sensor 42 can always accurately sense the light intensity, and maintaining the accuracy of the device's light sensing and curtain control.

[0037] In a specific embodiment, the air supply component 5 includes a micro air pump 51 and an air supply hose 52. Two loading blocks 102 are symmetrically installed on the housing 1. The frame 2 is installed on the two loading blocks 102. The micro air pump 51 is installed on one loading block 102. The two ends of the air supply hose 52 are respectively connected to the air outlet of the micro air pump 51 and the bottom of the hollow slider 31.

[0038] After the micro air pump 51 is started, it generates pressure to compress air and delivers it to the hollow slider 31 through the air supply hose 52. The air supply hose 52 ensures that the gas can be stably and smoothly transmitted from the micro air pump 51 to the hollow slider 31. Through this air supply method, a stable air source is provided for the rotating air blowing assembly 3, so that the air blowing hole 34 can continuously blow out gas, clean the dust on the surface of the photosensitive assembly 4, maintain the automatic cleaning function of the device, and ensure the long-term stable operation of the device.

[0039] In a specific embodiment, the driving component includes an electric slide rail 22, which is installed on the top of the frame 2. The hollow slider 31 is connected to the driving end of the electric slide rail 22 and is driven by the electric slide rail 22 to move along the length direction of the frame 2.

[0040] When the electric slide rail 22 is powered on, its drive end begins to move, driving the hollow slider 31 connected to it to move along the length of the frame 2. The electric slide rail 22 can control the moving speed and position of the hollow slider 31, thereby controlling the movement of the rotating air blowing component 3, realizing the adjustment of the position and angle of the photosensitive component 4, meeting the needs of light sensing in different environments, and improving the flexibility and accuracy of the device in light sensing.

[0041] In a specific embodiment, a controller 21 is installed at the end of the frame 2, and the electric curtain 101, electric slide rail 22, and miniature air pump 51 are all electrically connected to the controller 21.

[0042] The controller 21 is the core of the entire device. The light sensor 42 transmits the light intensity signal it senses to the controller 21. The controller 21 analyzes and processes the signal. When it determines that the position or angle of the photosensitive component 4 needs to be adjusted, the controller 21 sends a command to the electric slide rail 22 to start the electric slide rail 22, which drives the rotating air blowing component 3 and the photosensitive component 4 to move and flip. When it is necessary to clean the dust on the surface of the photosensitive component 4, the controller 21 controls the micro air pump 51 to start supplying air. When it is determined that the electric curtain 101 needs to be raised or lowered based on the comparison of indoor and outdoor light intensity fed back by the light sensor 42, the controller 21 sends a control command to the electric curtain 101 to realize the automatic raising and lowering of the electric curtain 101. Through the centralized control of the controller 21, all components work together to ensure that the entire device can operate automatically and accurately according to changes in light.

[0043] The specific principle of this utility model is as follows:

[0044] When this automatic light-sensing lifting device for curtains is working, firstly, the light sensor 42 transmits the indoor and outdoor light intensity signal to the controller 21. If the difference between indoor and outdoor light intensity reaches a preset value and the electric curtain 101 needs to be adjusted, the controller 21 sends a command to the electric curtain 101, and the electric curtain 101 makes the corresponding lifting action.

[0045] If the light intensity sensed by the light sensor 42 is lower than the preset threshold, the position and angle of the photosensitive component 4 need to be adjusted. The controller 21 controls the electric slide rail 22 to start. The drive end of the electric slide rail 22 drives the hollow slider 31 to move within the frame 2. The gear 33 on the hollow slider 31 rolls on the rack 23, causing the rotating rod 32 to rotate, so that the photosensitive components 4 installed at both ends of the rotating rod 32 flip, changing their position and angle to better sense the light.

[0046] During the flipping process of the photosensitive component 4, the controller 21 controls the micro air pump 51 to start. The micro air pump 51 supplies air to the hollow slider 31 through the air supply hose 52. After the air enters the cavity of the hollow slider 31, it is blown out from the air blowing hole 34 and blown towards the transparent tube 41 to clean the dust on the surface of the photosensitive sensor 42.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
