[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a heating and ventilation device for a heated building, including a housing 1, a first air duct 2 fixedly connected to one side of the housing 1, a fan 3 installed inside the first air duct 2, a filter screen 5 installed inside the first air duct 2, a plug-in block 6 symmetrically arranged at the lower end of the filter screen 5, a plug-in groove 7 symmetrically opened at the bottom of the first air duct 2, a telescopic rod 8 fixedly connected inside the plug-in groove 7, a snap-fit ​​block 9 fixedly connected to one end of the telescopic rod 8, a moving rod 10 fixedly connected to the lower end of the snap-fit ​​block 9, a spring 11 provided on the outer surface of the moving rod 10, and a pressing block 12 fixedly connected to one side of the moving rod 10. By setting the plug-in block 6, the plug-in groove 7, the telescopic rod 8, the snap-fit ​​block 9, the moving rod 10, the spring 11, and the pressing block 12, it is convenient to disassemble and assemble the filter screen 5, and thus convenient to replace it. The operation is simple and improves the convenience for the staff.

[0025] A heating pipe 15 is fixedly connected to one side of the first air duct 2. A one-way valve 16 is installed inside the heating pipe 15. Several heating plates 17 are installed inside the housing 1. A second air duct 18 is fixedly connected to one side of the housing 1. An installation rod 19 is fixedly connected to one side of the first air duct 2. An installation groove 20 is opened on one side of the installation rod 19. A drive motor 21 is fixedly connected inside the installation groove 20. A threaded rod 22 is fixedly connected to the output shaft of the drive motor 21. A threaded block 23 is threadedly connected to the outer surface of the threaded rod 22. A brush plate 25 is fixedly connected to one side of the threaded block 23. By setting up the installation rod 19, installation groove 20, drive motor 21, threaded rod 22, and threaded block 23, the brush plate 25 is driven to rewind, automatically cleaning the surface of the filter screen 5 and reducing labor intensity.

[0026] A limiting block 13 is fixedly connected to the lower end of the moving rod 10 to limit the moving distance of the moving rod 10. A limiting plate 4 is fixedly connected to the upper end of the filter screen plate 5. A guide block 14 is fixedly connected inside the first air duct 2 to facilitate the guidance of the brushed dust. A bearing 24 is fixedly connected to the lower end of the threaded rod 22. The bearing 24 is fixed to the bottom of the mounting groove 20. By setting the bearing 24, the rotation of the threaded rod 22 is facilitated. One side of the threaded block 23 is slidably connected to the side wall of the mounting groove 20 to prevent the threaded block 23 from rotating. The filter screen plate 5 is engaged with the first air duct 2 through the insertion block 6, the snap-fit ​​block 9, the moving rod 10, the spring 11, and the pressing block 12.

[0027] Working principle: When in use, power is connected, and fan 3 is started. Fan 3 draws in outside air, which is filtered through filter plate 5 and then mixed with hot air drawn from the room into the heating pipe 15 for preheating. The air then enters the housing 1 and is heated by heating plate 17 before entering the building through the second air duct 18 for heating. When the surface of filter plate 5 needs cleaning, drive motor 21 is started. Drive motor 21 drives threaded rod 22 to rotate, which in turn moves threaded block 23. Threaded block 23 moves brush plate 25 up and down to clean dust from the surface of filter plate 5. When filter plate 5 needs maintenance or replacement, press pressing block 12. Pressing block 12 causes spring 11 to contract, simultaneously moving moving rod 10. The snap-fit ​​block 9 moves, pressing the telescopic rod 8 to retract it. At the same time, the snap-fit ​​block 9 moves to disengage from the plug-in block 6, releasing the plug-in block 6. The limiting plate 4 can then be lifted to disassemble the filter screen 5. After maintenance or replacement of the filter screen 5, the filter screen 5 is placed into the first air duct 2, and the plug-in block 6 is inserted into the plug-in slot 7. The plug-in block 6 presses against the inclined surface of the snap-fit ​​block 9, causing the snap-fit ​​block 9 to move and press the telescopic rod 8. Simultaneously, the moving rod 10 moves, causing the pressing block 12 to move and the spring 11 to retract. When the plug-in block 6 is inserted to the bottom, the telescopic rod 8 and the spring 11 return to their original positions, thereby moving the moving rod 10 and the snap-fit ​​block 9. The snap-fit ​​block 9 engages with the plug-in block 6, completing the installation of the filter screen 5.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
