Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, and more specifically, to a ventilation exhaust port with adjustable angle. Background Art

[0002] Exhaust vents are used in many fields. Their main function is to ensure the circulation of indoor air by adjusting the air volume and direction, discharge polluted air, and keep the indoor environment clean and comfortable.

[0003] Existing exhaust vents also have certain disadvantages when in use. First, the lack of adjustability of exhaust vents does greatly limit their flexibility in practical applications. Under different environmental conditions, the demand for ventilation volume may be different. For example, in the cold winter, if the ventilation volume is too large, it may cause the indoor heat to be lost too quickly, increasing the heating cost; while in the hot summer, if the ventilation volume is insufficient, it will cause the indoor temperature to be too high, affecting the living comfort. However, since the existing exhaust vents are not adjustable, we cannot adjust the air volume and wind direction according to actual needs, which undoubtedly brings great difficulties to the control of the indoor environment. Secondly, non-adjustable exhaust vents may also cause energy efficiency problems. In some cases, we may not need a lot of ventilation, but because the vent cannot be adjusted, it will still run at a fixed air volume and wind direction, which will not only cause energy waste, but also may increase operating costs. Especially in some places that need to run for a long time, such as offices, shopping malls, etc., this phenomenon of energy waste may be more obvious. In addition, non-adjustable exhaust vents may also have a negative impact on indoor air quality. If the ventilation volume is too large, it may bring outdoor pollutants into the room, affecting the indoor air quality; if the ventilation volume is insufficient, the indoor polluted air cannot be discharged in time, resulting in a decrease in indoor air quality. In this case, even if exhaust vents are installed, the expected ventilation effect cannot be achieved. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model uses the power of the motor to rotate the slave gear meshing with the main gear, and the rotation of the slave gear drives the connecting belts 1 to 8 to rotate, thereby driving the nine blades to adjust their angles. Compared with the traditional device, this device can more accurately point to the area that needs to be exhausted, so as to more effectively exhaust the indoor air.

At this time, the reaction force of the spring 2 resets the handle. Compared with the traditional device, this device can be operated quickly and simply when the filter plate needs to be cleaned or replaced, thereby reducing the workload and downtime of maintenance personnel. At the same time, the rapid replacement of the filter plate can ensure the continuous and efficient operation of the ventilation system, maintain the circulation of indoor air, and avoid the accumulated dust and dirt that may damage the ventilation duct and shorten its service life.

Compared with the traditional device, this device can more accurately point to the area that needs to be exhausted, so as to more effectively exhaust the indoor air.

[0037] When installing the filter plate 25, after sliding the card plate 20 on the side of the filter plate 25 from the inside of the groove 17 to the deepest part, the card plate 20 is pushed into the inside of the slide groove 18 for clamping after being subjected to the reaction force of the spring 19. When the filter plate 25 needs to be replaced, the staff pushes the handle 23, and the movable rod 22 moves forward inside the circular hole 21, thereby pushing the card plate 20 so that the spring 19 is in a compressed state and the filter plate 25 is taken out. At the same time, the reaction force of the spring 24 will reset the handle 23.
