Description

Technical Field

[0001] This application relates to the field of blind technology, specifically a rainproof blind. Background Technology

[0002] Venetian blinds are a type of window that originated in China and has a long history and cultural significance. In ancient times, venetian blinds were called straight-lattice windows or horizontal-lattice windows, and were usually made of wood or bamboo. They were mainly used for decoration and ventilation. Modern venetian blinds are mostly made of materials such as zinc steel and aluminum alloy, and have more functionality and decoration.

[0003] Existing venetian blinds often have poor sealing between the slats, allowing rainwater to easily seep into the room through the gaps. They also require manual closing and cannot be closed in time during rainfall, resulting in poor rain protection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a rainproof louver that can seal adjacent louvers and the gap between the louvers and the window frame, optimizing the sealing effect of the louver. It can also automatically close during rainfall to prevent rainwater from entering the room through the louvers. It requires no manual operation, saving manpower, and improves the waterproof effect of the louvers. This solves the problems of existing louvers, which often have poor sealing between the louvers, allowing rainwater to easily enter the room through the gaps between the louvers, and require manual closing, making it difficult to close in time during rainfall and resulting in poor rainproof performance.

[0005] To achieve the above objectives, this application provides the following technical solution: a rainproof louver, comprising an outer frame, wherein equidistantly arranged rotating shafts are rotatably connected inside the outer frame, and louvers are fixedly sleeved on the outer circumferential surface of each rotating shaft, and mating plates are fixedly connected at the top and bottom diagonal positions of each louver, and adjacent louvers are tightly fitted together by the mating plates, and a sealing strip is fixedly connected to the inner wall of each mating plate.

[0006] The outer frame houses a motor, with an output shaft at the top of the motor rotatably connected to equidistantly arranged worm gears. A worm is fixedly fitted onto the outer circumference of each shaft, and the worm gears are connected to the worm wheels. A rain sensor is located on the back of the outer frame, and a controller is located inside the outer frame. Two side plates are located on the inner wall of the outer frame, with a sealing sheet fixedly connected to the side of each side plate near the louvers. Equidistantly arranged fixing plates are fixedly connected to the inner wall of the outer frame, with a sliding rod slidably inserted into the interior of each fixing plate. The end of the sliding rod near the side plate is fixedly connected to the outer surface of the side plate. Springs are provided between the fixing plates and the side plates.

[0007] The above solution addresses the issue that existing venetian blinds often have poor sealing between the slats, allowing rainwater to easily seep into the room through the gaps. Furthermore, they require manual closing and cannot be closed promptly during rainfall, resulting in poor rain protection. By installing butt joint plates at the top and bottom diagonally of the slats, and sealing strips on the inner walls of these plates, adjacent slats can be tightly sealed. Spring-loaded side plates and sealing sheets on both sides of the inner wall of the outer frame further seal the sides of the slats, optimizing the sealing effect. Finally, by incorporating rain sensors, controllers, motors, worm gears, and worm shafts, the blinds automatically close during rainfall, preventing rainwater from entering the room without manual intervention, saving manpower and improving the waterproofing effect.

[0008] Furthermore, the raindrop sensor is electrically connected to the controller, and the motor is electrically connected to the controller.

[0009] Through the above scheme, the raindrop sensor can detect rainwater in real time and feed the detection results back to the controller. The controller then controls the motor based on the information fed back by the raindrop sensor. When it rains, after receiving the rainfall information fed back by the raindrop sensor, the controller immediately starts the motor to drive the worm gear to rotate. The worm gear drives the rotating shaft and louvers to rotate and close through the worm.

[0010] Furthermore, the outer frame has side compartments inside, and the motor, worm gear, worm, and controller are all located inside the side compartments.

[0011] The above solution allows the motor, worm gear, worm, and controller to be housed inside the side compartment, facilitating the inspection and maintenance of each component.

[0012] Furthermore, a door panel is hinged to the front of the side compartment, and an observation window is provided inside the door panel.

[0013] The above solution can separate the components inside the side compartment from the outside through the door panel, protect the components inside the side compartment, and observe the working status inside the side compartment through the observation window.

[0014] Furthermore, a lock is provided on the front of the door panel, and the door panel is fixedly connected to the outer frame through the lock.

[0015] The above solution allows for the use of locks to secure the door panel and outer frame, preventing the door panel from opening and closing easily.

[0016] Furthermore, a lower sealing plate is fixedly connected to the inner bottom wall of the outer frame, a mating plate is fixedly connected to the top of the lower sealing plate, and a sealing strip is fixedly connected to the inner wall of the mating plate at the top of the lower sealing plate. The lower sealing plate is tightly fitted to the bottom of the lowest louver through the mating plate at its top.

[0017] The above solution seals the bottom of the louvers with the lower sealing plate and the connecting plate at its top, preventing rainwater from seeping in from the bottom of the louvers.

[0018] Furthermore, an upper sealing plate is fixedly connected to the inner top wall of the outer frame, a mating plate is fixedly connected to the bottom of the upper sealing plate, and a sealing strip is fixedly connected to the inner wall of the bottom mating plate of the upper sealing plate. The upper sealing plate is tightly fitted to the top of the uppermost louver through its bottom mating plate.

[0019] The above solution seals the top of the louvers with the upper sealing plate and the bottom mating plate, preventing rainwater from seeping in from the top of the louvers.

[0020] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each slide rod, and the limiting ring is located at the end of the fixed plate away from the louver.

[0021] The above method restricts the sliding rod, preventing it from easily detaching from the fixed plate and improving the stability of the sliding rod and side plate movement.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This rainproof louver features interlocking plates at the top and bottom diagonally of the louvers, along with sealing strips on the inner walls of these plates. This ensures a tight seal between adjacent louvers. Spring-loaded side plates and sealing sheets on both sides of the inner wall of the outer frame further enhance the seal, optimizing the louver's sealing performance. A rain sensor, controller, motor, worm gear, and worm shaft automatically close the louvers during rainfall, preventing rainwater from entering the room. This eliminates the need for manual operation, saving manpower and improving the waterproofing effect. It solves the problems of poor sealing and the inability to automatically close during rainfall, resulting in inadequate rain protection in existing louvers. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figure 1 , Figure 5 and Figure 9 In this embodiment, a rainproof louver includes an outer frame 1. The inner side of the outer frame 1 is rotatably connected with equidistantly arranged pivots 2. Each pivot 2 has a louver 3 fixedly fitted onto its outer circumferential surface. Each louver 3 has a mating plate 4 fixedly connected to its top and bottom diagonal positions. Adjacent louvers 3 are tightly fitted together through the mating plates 4. Each mating plate 4 has a sealing strip fixedly connected to its inner wall.

[0038] Please see Figure 2 , Figure 4 and Figure 5 The outer frame 1 has a motor 5 inside, and the top of the motor 5 is rotatably connected to equidistant worm gears 6 through an output shaft. Each rotating shaft 2 has a worm 7 fixedly sleeved on its outer circumference, and the worm 7 is connected to the worm gear 6 for transmission. The back of the outer frame 1 has a raindrop sensor 8, and the outer frame 1 has a controller 9 inside.

[0039] Please see Figure 2 , Figure 3 and Figure 7 The inner wall of the outer frame 1 is provided with two side plates 10. Each side plate 10 is fixedly connected to a sealing sheet on the side near the louver 3. The inner wall of the outer frame 1 is fixedly connected with equidistant fixed plates 11. Each fixed plate 11 is slidably inserted with a slide rod 12 inside. The end of the slide rod 12 near the side plate 10 is fixedly connected to the outer surface of the side plate 10. A spring 13 is provided between the fixed plate 11 and the side plate 10.

[0040] Please see Figure 2 , Figure 4 and Figure 5 The raindrop sensor 8 is electrically connected to the controller 9, and the motor 5 is electrically connected to the controller 9. The raindrop sensor 8 can detect rainwater in real time and feed back the detection results to the controller 9. The controller 9 then controls the motor 5 based on the information fed back by the raindrop sensor 8. When it rains, after receiving the rainfall information fed back by the raindrop sensor 8, the controller 9 immediately starts the motor 5 to drive the worm gear 6 to rotate. The worm gear 6 drives the rotating shaft 2 and the louvers 3 to rotate and close through the worm 7.

[0041] Please see Figure 1 , Figure 4 and Figure 5 The outer frame 1 has a side compartment 14 inside, where the motor 5, worm gear 6, worm 7, and controller 9 are all located. This arrangement facilitates the inspection and maintenance of each component.

[0042] Please see Figure 1 The side compartment 14 is hinged to a door panel 15 on the front. The door panel 15 has an observation window 16 inside. The door panel 15 can be used to separate the components inside the side compartment 14 from the outside, thus protecting the components inside the side compartment 14. The operation status inside the side compartment 14 can be observed through the observation window 16.

[0043] Please see Figure 1 The door panel 15 is provided with a lock 17 on the front. The door panel 15 is fixedly connected to the outer frame 1 through the lock 17. The lock 17 can fix the door panel 15 and the outer frame 1, preventing the door panel 15 from being opened and closed easily.

[0044] Please see Figure 4 , Figure 6 and Figure 10The bottom inner wall of the outer frame 1 is fixedly connected to a lower sealing plate 18, and the top of the lower sealing plate 18 is fixedly connected to a mating plate 4. A sealing strip is fixedly connected to the inner wall of the mating plate 4 at the top of the lower sealing plate 18. The lower sealing plate 18 is tightly fitted to the bottom of the lowest louver 3 through the mating plate 4 at its top. The bottom of the louver is sealed by the lower sealing plate 18 and the mating plate 4 at its top, preventing rainwater from seeping in from the bottom of the louver.

[0045] Please see Figure 4 , Figure 6 and Figure 8 An upper sealing plate 19 is fixedly connected to the inner top wall of the outer frame 1. A mating plate 4 is fixedly connected to the bottom of the upper sealing plate 19. A sealing strip is fixedly connected to the inner wall of the mating plate 4 at the bottom of the upper sealing plate 19. The upper sealing plate 19 is tightly fitted to the top of the uppermost louver 3 through the mating plate 4 at its bottom. The top of the louver is sealed by the upper sealing plate 19 and the mating plate 4 at its bottom to prevent rainwater from seeping in from the top of the louver.

[0046] Please see Figure 2 and Figure 7 Each slide rod 12 has a limiting ring 20 fixedly sleeved on its outer circumference. The limiting ring 20 is located at the end of the fixed plate 11 away from the louver 3 to restrict the slide rod 12, prevent the slide rod 12 from easily falling off the fixed plate 11, and improve the stability of the movement of the slide rod 12 and the side plate 10.

[0047] This embodiment of a rainproof louver features a butt plate 4 at the top and bottom diagonally of the louver 3, and a sealing strip on the inner wall of the butt plate 4, ensuring a tight seal between adjacent louvers 3. Side plates 10, restrained by springs 13, and sealing sheets are installed on both sides of the inner wall of the outer frame 1, ensuring a seal on both sides of the louver 3, thus optimizing the louver's sealing effect. Furthermore, a rain sensor 8, controller 9, motor 5, worm gear 6, and worm 7 are incorporated to automatically close the louver during rainfall, preventing rainwater from entering the room through the louver. This eliminates the need for manual operation, saving manpower and improving the waterproof effect of the louver. It solves the problems of poor sealing and inability to automatically close during rainfall, resulting in poor rainproof performance in existing louvers.

[0048] It should be noted that the louvers 3 and the connecting plate 4 are integrally formed, which facilitates production and assembly.

[0049] The working principle of the above embodiments is as follows:

[0050] The controller 9 is electrically connected to an external control device, which can issue commands to the controller 9. The controller 9 then controls the starting and stopping of the motor 5. When the motor 5 starts, it drives the worm gear 6 to rotate via its output shaft. The worm gear 6, in turn, drives the rotating shaft 2 and the louvers 3 to rotate synchronously via the worm 7, thereby controlling the opening and closing and the opening angle of the louvers 3. The rain sensor 8 can detect rainwater in real time and feed the detection results back to the controller 9. The controller 9 then controls the motor 5 based on the information from the rain sensor 8. When it rains, the controller 9 receives the rainfall information from the rain sensor 8 and immediately starts the motor 5 to drive the worm gear 6. The rotation of the blinds causes them to close automatically without manual operation, thus optimizing their rainproof performance. The interlocking plates 4 at the top and bottom of the blinds 3, along with the sealing strips on the inner walls of the interlocking plates 4, ensure that adjacent blinds 3 fit tightly together, optimizing the sealing effect between the blinds 3. When the blinds 3 open, they push the side plates 10 and the sealing strips to move. The side plates 10 compress the springs 13, and the springs 13 exert a reaction force on the side plates 10 with their own elasticity, causing the side plates 10 to automatically move the sealing strips back and fit tightly against both sides of the blinds 3 when the blinds 3 are closed, sealing both sides of the blinds 3 and further optimizing the sealing and rainproof performance of the blinds.
