Description

Technical Field

[0001] This utility model belongs to the field of ventilation equipment technology, specifically relating to a solar-powered ventilation system for doors and windows. Background Technology

[0002] Currently, ventilation in door and window areas mainly relies on natural ventilation or traditional mains-powered exhaust systems, which have significant technical drawbacks. On the one hand, natural ventilation is constrained by environmental factors such as outdoor wind speed and indoor-outdoor temperature differences, resulting in slow air exchange speed and low efficiency. This makes it difficult to meet the needs of rapid indoor air renewal in modern enclosed buildings, easily leading to the accumulation of pollutants such as formaldehyde and odors, affecting indoor air quality. On the other hand, traditional mains-powered exhaust systems continuously consume grid power, resulting in high operating costs, failing to meet the environmental trend of energy conservation and emission reduction, and also presenting problems such as complex wiring and installation limitations due to power supply location constraints.

[0015] This utility model provides, for example Figure 1-5 The illustrated door and window solar-powered ventilation system includes an electrical structure and a ventilation structure. The electrical structure consists of a mounting plate 1 and a solar panel 7. The mounting plate 1 can be installed on the wall on one side of the door or window. A connecting rod 2 is fixed to the outer wall of one side of the mounting plate 1. A connecting seat 3 is fixed to one end of the connecting rod 2, and a positioning post 4 is fixed inside the connecting seat 3. An mounting rod 5, which is fixedly connected to the solar panel 7, is rotatably connected to the positioning post 4. A threaded groove is opened on the outer wall of the positioning post 4, and a positioning ring 6 is threadedly connected to the positioning post 4. A through hole is opened on the outer wall of one side of the connecting seat 3 for the positioning ring 6 to move. The rotatable mounting rod 5 can adjust the angle of the solar panel 7. At the same time, rotating the positioning ring 6 makes the positioning ring 6 fit tightly against one side of the mounting rod 5, which can fix the position of the mounting rod 5 and the solar panel 7 and ensure the stability of the solar panel 7 when it is working. The exhaust structure consists of an outer casing 8 and multiple exhaust fans 12 installed inside the outer casing 8. The outer casing 8 can be installed on a window frame. The lower half of the outer casing 8 has a receiving cavity, and a storage battery 9 and a control box 10 are installed inside the receiving cavity. The storage battery 9 is connected to a solar panel 7 via wires. The solar panel 7 generates electricity to power the exhaust fans 12, eliminating the need for mains power, making it more energy-efficient and environmentally friendly. At the same time, the solar panel 7 generates electricity to charge the storage battery 9, which can store excess electrical energy and continuously power the exhaust fans 12 when the weather is bad. The control box 10 contains a controller and a signal receiver. The signal receiver can receive control signals from an external remote control to achieve remote control of the exhaust fans 12. The lower half of the outer wall of the outer casing 8 has a through groove, and a protective plate 11 is fixed to the outer wall of the outer casing 8 to cover the through groove. The through groove facilitates the installation and maintenance of the storage battery 9 and the control box 10, and the protective plate 11 can prevent dust and water. The outer casing 8 has an external ventilation plate 13 and an internal ventilation plate 14 on both sides. A metal insect screen 15 is installed inside both the external ventilation plate 13 and the internal ventilation plate 14. Two mounting holes are opened on the outer walls of both sides of the outer casing 8. Magnetic blocks 16 for adsorbing the external ventilation plate 13 and the internal ventilation plate 14 are fixed in the mounting holes. The magnetic blocks 16 adsorb the external ventilation plate 13 and the internal ventilation plate 14, which facilitates quick installation and removal of the external ventilation plate 13 and the internal ventilation plate 14. It is also convenient to clean and replace the metal insect screen 15 later. Multiple limiting blocks 17 are fixed on one side of the outer wall of the external ventilation plate 13. A sealing plate 18 is movably connected inside the limiting block 17. In rainy or snowy weather, the sealing plate 18 is inserted into the limiting block 17.

[0018] Working principle: The solar-powered ventilation system for doors and windows first fixes the mounting plate 1 to the wall on one side of the door and window, and then installs the outer shell 8 in the reserved position of the window frame. Then, the angle of the solar panel 7 is adjusted, the mounting rod 5 is rotated to rotate around the positioning post 4 to the best position for receiving light, and then the positioning ring 6 is rotated to move along the threaded groove of the positioning post 4 until the positioning ring 6 is tightly attached to the mounting rod 5, thereby fixing the angle of the solar panel 7. The solar panel 7 converts solar energy into electrical energy under sunlight. Part of it directly powers the exhaust fan 12 inside the outer casing 8 to meet the real-time ventilation needs. Excess electrical energy is transmitted through wires to the battery 9 in the cavity of the outer casing 8 for storage. When there is insufficient sunlight, such as on cloudy days or in the evening, the battery 9 automatically powers the system to ensure the continuous and stable ventilation function. The external remote control sends a command to the signal receiver inside the control box 10. The signal receiver transmits the command to the controller, which drives multiple exhaust fans 12 to start synchronously. The indoor polluted air enters the interior of the outer shell 8 through the inner ventilation plate 14 and is then discharged to the outside through the outer ventilation plate 13, forming a rapid air circulation. During this period, the metal insect screen 15 of the outer ventilation plate 13 and the inner ventilation plate 14 prevents mosquitoes and debris from entering. When encountering rainy or snowy weather, the sealing plate 18 is inserted into the limiting block 17 of the outer vent plate 13. The protective plate 11 supports the sealing plate 18, thereby sealing the outer shell 8 and preventing rain and snow from entering. At the same time, the protective plate 11 blocks the through groove to prevent dust from entering the receiving cavity and affecting the operation of the components.
