[0002] Heating, ventilation and air conditioning (HVAC) engineering typically refers to heating engineering, ventilation and air conditioning engineering, and boiler and boiler room equipment engineering. HVAC vents are opening components in ventilation systems used to introduce fresh outdoor air or exhaust stale indoor air; they are key channels for achieving indoor and outdoor air exchange.

[0003] When in use, ventilation vents in HVAC engineering are usually vented with the air outlet facing downwards, and the air blows directly downwards, which may cause some discomfort to the staff and has poor practicality. At the same time, after long-term use, the surface of the ventilation vent may accumulate a lot of dust, which will reduce the ventilation efficiency and may also have an adverse effect on air quality.

Square plates are symmetrically fixedly connected to the outer surface of the vent device body. A take-up reel is rotatably connected to the outer surface of the square plates. A second remote control motor is fixedly connected to the outer surface of the square plates. One end of the output shaft of the second remote control motor is fixedly connected to the outer end of the take-up reel. The outer surface of the take-up reel is fixedly connected to...

An airflow adjustment component is installed inside the ventilation opening device body 1, and a reciprocating cleaning component is installed on the outer surface of the ventilation opening device body 1. The airflow adjustment component includes a first toothed plate 2. A through-hole groove 6 is opened on the outer surface of the ventilation opening device body 1, and the through-hole groove 6 is slidably connected to the outer surface of the first toothed plate 2.

A second gear 5 is fixedly connected to one end of the output shaft of the first remote control motor 3. By setting a first gear plate 2, the movement of the first gear plate 2 can drive multiple first gears 7 meshing with it to rotate synchronously. The rotation of the first gear 7 drives the rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the baffle 15 to adjust the angle. The outer surface of the second gear 5 meshes with the outer surface of the first gear plate 2. The outer surface of the first gear plate 2 meshes with the outer surface of the first gear 7, so that the second gear 5 can drive the first gear plate 2 to move and cause multiple first gears 7 meshing with it to rotate synchronously.

[0018] The reciprocating cleaning assembly includes a cleaning roller brush 11. A first groove 17 is formed on the outer surface of the vent device body 1. A first L-shaped plate 13 is slidably connected inside the first groove 17. The outer surface of the first L-shaped plate 13 is rotatably connected to the outer end of the cleaning roller brush 11. A spring 18 is fixedly connected to the inner side of the first groove 17. The end of the spring 18 away from the first groove 17 is fixedly connected to the outer surface of the first L-shaped plate 13. Square plates 21 are symmetrically fixedly connected to the outer surface of the vent device body 1. A take-up reel 20 is rotatably connected to the outer surface of the square plates 21. A second remote control motor 12 is fixedly connected to the outer surface of the square plates 21. One end of the output shaft of the second remote control motor 12 is fixedly connected to the outer end of the take-up reel 20. A pull rope 19 is fixedly connected to the outer surface of the take-up reel 20. A second L-shaped plate 10 is slidably connected to the outer surface of the vent device body 1. The end of the cleaning roller brush 11 away from the first L-shaped plate 13 is rotatably connected to the outer surface of the second L-shaped plate 10. By setting the cleaning roller brush 11, the cleaning roller brush 11 reciprocates while... The cleaning roller brush 11 rotates under the meshing transmission of the third gear 16 and the second toothed plate 14 to clean the main body 1 of the ventilation device. The end of the cleaning roller brush 11 near the first L-shaped plate 13 is fixedly connected to the third gear 16, and the top of the main body 1 of the ventilation device is fixedly connected to the second toothed plate 14, so that the third gear 16 and the second toothed plate 14 can mesh and transmit power. The outer surface of the main body 1 of the ventilation device is provided with a second sliding groove 9, and the interior of the second sliding groove 9 is slidably connected to the outer surface of the second L-shaped plate 10, so that the second L-shaped plate 10 can slide on the outer surface of the main body 1 of the ventilation device. The outer surface of the second toothed plate 14 meshes with the outer surface of the third gear 16, so that the third gear 16 can rotate when it moves. The outer surface of the cleaning roller brush 11 contacts the top of the main body 1 of the ventilation device, so that the cleaning roller brush 11 can clean the top of the main body 1 of the ventilation device. The end of the pulling rope 19 away from the take-up wheel 20 is fixedly connected to the outer surface of the first L-shaped plate 13, so that the pulling rope 19 can pull the first L-shaped plate 13 to move inside the first sliding groove 17.

[0019] Working principle: When in use, the operator starts the first remote control motor 3. The output shaft of the first remote control motor 3 rotates, which drives the second gear 5 to rotate. The rotation of the second gear 5 drives the first gear plate 2 to move. The movement of the first gear plate 2 drives the multiple first gears 7 meshing with it to rotate synchronously. The rotation of the first gears 7 drives the rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the baffle 15 to adjust the angle, thereby realizing the adjustment of the wind direction and avoiding the wind blowing directly downwards, which would cause discomfort to the operator and improve the practicality of the device.

[0020] When dust accumulates on the top of the vent device body 1 after prolonged use, the second remote control motor 12 is activated. The output shaft of the second remote control motor 12 reciprocates, driving the take-up reel 20 to rotate. As the take-up reel 20 winds up the pull rope 19, the pull rope 19 causes the first L-shaped plate 13 to slide within the first groove 17. The first L-shaped plate 13 then moves the cleaning roller brush 11, which cleans the top of the vent device body 1. Simultaneously, the movement of the first L-shaped plate 13 applies tension to the spring 18, causing the spring 18 to stretch. The movement of the cleaning roller brush 11 also drives the third gear 16 to move. The third gear 16 meshes with the second gear plate 14, causing the third gear 16 to rotate and drive the cleaning roller brush 11 to rotate. When the take-up reel 20 releases the pull rope 19, the tension of the spring 18 causes the first L-shaped plate 13 to slide in the first groove 17 in the opposite direction. The first L-shaped plate 13 drives the cleaning roller brush 11 to move in the opposite direction, so that the cleaning roller brush 11 can clean the top of the vent device body 1 back and forth, thereby improving the cleaning effect of the cleaning roller brush 11 on the top of the vent device body 1 and avoiding the situation where a large amount of dust adheres to the surface of the vent, which reduces the ventilation efficiency and has an adverse effect on the air quality.
